Description

  The present invention relates to a massage nozzle and a massage device, and more particularly to a massage nozzle and a massage device that can generate a negative pressure by a swirling flow of water and cause a suction pressure to act on the body.

  Massage devices that massage the surface of the body's skin and activate blood circulation for the purpose of beauty and health promotion are widely used. As such a conventional massager, for example, an electric shoulder pad, a waist pad, a device that uses a suction port that is in a reduced pressure state, and the like are known.

  As a massaging apparatus using water, an opening for introducing a pressurized liquid in the inner tangential direction into a cylindrical body with one end closed and the other end opened, and outside air at the central position of the cylindrical body at the closed end. There has been devised a massager that is provided with an opening to be introduced, and further provided with a guide tube on the outside of the cylindrical body so as to be sucked in the vicinity of the water outlet (for example, see Patent Document 1). In this invention, the discharged water flows in a direction reversed by the guide tube, so that the body can be sucked in a state where the negative pressure portion in the vicinity of the water discharge port is enlarged.

Moreover, the suction washing device which provides the outflow part opened by the front part side of the expanded guide part and discharges discharged water is disclosed (for example, patent document 2).
Furthermore, a massage washer using a suction action by a swirling flow has been disclosed (for example, Patent Document 3) in which a steam / water separator plate is provided to enable use in the air.

  In the case of a massager that uses a swirling flow of water, there is a problem that water scatters around from the water outlet. For example, when the massage device described in Patent Document 1 is used in the air, there is little scattering of water while the guide tube is applied to the skin, but when the guide tube is separated from the skin, the water discharge is There is a problem that it is scattered in a conical shape and uncomfortable because it unnecessarily wets the user, the person around him or the bathroom wall. Similar problems also occur in the suction washer described in Patent Document 2.

  On the other hand, in the case of the massage washer described in Patent Document 3, the swirl flow spouting portion and the suction portion are separated by the air / water separator plate, and the swirl flow passing through the passage hole of the flow-through plate is provided at the tip. Spattering is prevented by hitting the prevention curved part. However, in the case of this massage washer, since the water discharge part and the suction part are separated, the overall length is long and the suction force is also reduced, and effects such as pressing and vibration caused by the swirling flow do not act on the skin. Further, the suction part is smaller than the spout and has a small area on which the suction force acts. Furthermore, since the suction port sticks to the skin, there is a problem that it is difficult to move the massager body.

  The present invention has been made in view of these problems, and its purpose is that even when it is opened to the atmosphere, there is no scattering of water to the surroundings, and suction of a large area is possible. Also in the case of moving, it is providing the massage nozzle which can move smoothly, and a massage apparatus using the same.

In order to achieve the above object, the first massage nozzle of the present invention is provided so as to form a swirling flow in the room and to discharge the swirling flow to form a negative pressure region. A swirling chamber having a water outlet, and a water spray plate provided at a tip of the water outlet, having an opening in the center and having a plurality of water holes around the opening, and water is discharged from the water outlet. The swirl component of the water flow discharged from the sprinkling hole is suppressed more than the swirl component of the water flow discharged from the spout and discharged from the opening, and the user is released by the water discharged from the opening and the plurality of sprinkling holes. A water film is formed between the treatment site and the water spray plate, and the treatment site of the user can be sucked into the opening .

  According to the above configuration, since the suction massage is realized by providing the opening serving as the suction port, the swirling flow is rectified by the water spray hole and discharged in a shower shape. Can be suppressed. Moreover, since the water spray hole which has a rectification | straightening effect | action is provided in the front-end | tip of the spout, a swirl flow can be brought closer to a to-be-processed part, and the massage effect by a swirl flow can be acquired. Furthermore, since shower-like water discharge is obtained from the water spray holes in the open state, it can be used as a normal shower head.

Further, the second massage nozzle of the present invention comprises a water inlet provided to form a swirl flow in the room, and a water discharge port provided to discharge the swirl flow and form a negative pressure region. A swirl chamber having a substantially cylindrical guide portion that protrudes from the spout, and provided at the tip of the guide portion, having an opening at the center, and having a plurality of water spray holes around the opening. A swirling component of the water flow discharged from the spout and discharged from the sprinkling hole is suppressed more than the swirl component of the water flow discharged from the spout and discharged from the opening; The water discharged from the plurality of water spray holes can be sucked toward the opening of the user's treatment site while forming a water film between the treatment site of the user and the tip of the guide portion. and said that the content was.

  Also in the said structure, the effect similar to the massage nozzle mentioned above is acquired by providing a watering board. Furthermore, according to the said structure, scattering of the swirling flow discharge | released from the water outlet can be suppressed more effectively by providing a guide part. Furthermore, if the guide part is detachable, a suction force, a stimulation feeling, a suction area, etc. according to the user's preference can be selected and used as appropriate.

  Here, if the opening is larger than the spout, a suction region can be sufficiently secured, and a massage effect and a biological effect can be enhanced. Furthermore, the massage nozzle body can be formed in a compact manner, and the handling becomes easy.

  In addition, if a rectifying plate provided on the surface of the water spray plate facing the water discharge port or the inner peripheral wall of the guide portion is further provided, the rectifying plate plays the role of a stationary blade and further enhances the rectifying effect. be able to.

  Moreover, the said guide part makes the half of the difference of the diameter of the said water outlet and the diameter of the said opening of the watering board L1, and the angle which the water discharge flow discharged from the said water outlet forms with respect to the surface containing the said water outlet If it is assumed that the length from the spout to the water spray plate is not less than (L1 × tan θ), the swirling flow discharged from the spout is surely Colliding with the inner peripheral wall or watering plate of the guide part, the rectifying effect is ensured.

  Further, in the second massage nozzle, a substantially disc-shaped stopper having an opening in the center, and a substantially cylindrical ring portion projecting substantially perpendicularly to the stopper from a peripheral edge of the opening of the stopper, If the movable element having the movable element is movably provided in the guide portion, it is possible to enhance both the scattering prevention effect and the suction massage effect according to the position of the movable element.

A swirl chamber having a water inlet provided to form a swirl flow in the room, and a water discharge port provided to discharge the swirl flow to form a negative pressure region, than the water discharge port. A substantially cylindrical guide portion provided to protrude, and a water spray plate provided at the tip of the guide portion, having an opening in the center and having a plurality of water spray holes around the opening, and having an opening in the center A mover having a substantially disc-shaped stopper and a substantially cylindrical ring portion projecting substantially perpendicularly to the stopper from the periphery of the opening of the stopper is movable in the guide portion. Provided, the guide portion is L2 which is half the difference between the diameter of the water outlet and the diameter of the opening of the stopper, and an angle formed by a water discharge flow discharged from the water outlet with respect to a surface including the water outlet When θ is θ, from the water outlet in the open water discharge state Further, if the length to the stopper is projected so as to be equal to or greater than (L2 × tan θ), the swirling flow discharged from the water outlet is surely the inner peripheral wall of the guide portion, the water spray plate, or the movable plate. Colliding with the child, the rectification effect is secured.

  On the other hand, in the first massage nozzle, a substantially disc-shaped stopper having an opening in the center, and a substantially cylindrical ring portion protruding substantially perpendicularly to the stopper from the periphery of the opening of the stopper, If the movable element having the movable element is movably provided in the swirl chamber, it is possible to enhance both the scattering prevention effect and the suction massage effect according to the position of the movable element.

  Here, if the maximum outer dimension of the stopper is larger than the opening of the water spray plate, there is no fear that the mover will fall out of the guide portion, and the handling becomes easy.

  In addition, if the ring portion is provided so as to be able to protrude from the opening of the water spray plate, the protrusion height of the ring portion can be easily changed by allocating the ring portion to the treated portion, thereby preventing scattering. An advantageous state and a state advantageous for suction massage can be appropriately switched and used.

  In addition, if the water spray plate further includes a peripheral protrusion that protrudes from the peripheral edge of the opening of the water spray plate toward the water discharge port, the swirling water discharge is the water spray plate at the time of non-contact with the target site. It is possible to suppress overflowing from the opening and scattering, and the rectifying effect is enhanced. On the other hand, at the time of contact with the non-processed portion, the swirling flow can overflow beyond the peripheral protrusion, so that a massage effect by “twisting” or “vibration” due to the swirling flow can be obtained.

  On the other hand, the massage device of the present invention comprises water supply means and any one of the massage nozzles described above, and supplies water to the swirl chamber from the water supply means via the water inlet of the massage nozzle. Is characterized in that suction massage using a negative pressure portion formed at the water discharge port of the massage nozzle can be performed.

  According to the above-described configuration, it is possible to prevent scattering of discharged water at the time of non-contact and can be used as a normal shower. Further, in suction massage, it is possible to provide a massage device that can smoothly move many parts of a human body over a wide range. it can.

  According to the present invention, even when opened to the atmosphere, there is no scattering of water to the surroundings, suction of a large area is possible, even when moving in contact with the skin, it can move smoothly, It is possible to provide a massage nozzle that can be used as a normal shower head and a massage device using the same.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 are schematic views showing a massage nozzle according to an embodiment of the present invention. 1 is a perspective view of the massage nozzle 1, FIG. 2 is a front view, FIG. 3 is a cross-sectional view taken along line AA in FIG. 2, and FIG. 4 is an end view taken along line BB in FIG. is there.
The massage nozzle 1 of the present embodiment has a turning part 2 and a connection part 4. The swivel unit 2 includes a swirl chamber 8 that is surrounded by the peripheral side wall 8W and has a substantially circular cross section. One end of the swirl chamber 8 is opened to form a water discharge port 7.
A water inlet 6 is provided on the peripheral side wall 8W. Water is introduced from the water inlet 6 in a substantially tangential direction of the peripheral side wall 8W of the swirl chamber 8 to form a swirl flow CF along the peripheral side wall 8W. The connecting portion 4 is provided with an introduction path 5 that is open to communicate with the water inlet portion 6.
On the other hand, a water spray plate 12 is provided at the tip of the spout 7. The water spray plate 12 is provided with an opening 12b at the center thereof, and a plurality of water spray holes 12a are provided around the opening 12b.

  In order to efficiently form the swirl flow CF in the swirl chamber 8, it is desirable that the water inlet 6 is opened in the tangential direction of the peripheral wall 8W of the swirl chamber. However, the swirl flow CF is formed even when the water inlet 6 is not accurately opened in the tangential direction with respect to the peripheral side wall 8W and there is a “deviation” from the tangential direction in the opening direction or the opening position. It only has to be done.

  Here, as shown in FIG. 4, the “water inlet 6” includes a water inlet 6 </ b> A that substantially determines the introduction direction of the water flow introduced into the swirl chamber 8, and an opening in the swirl chamber 8 of the water inlet 6 </ b> A. And the water inlet 6B which is an end. In the case of the massage nozzle 1 of this specific example, the direction of introduction of the water flow introduced into the swirl chamber 8 is the direction of the arrow S. Therefore, the water intake channel 6A corresponds to a water channel provided in the direction of the arrow S. Further, the water inlet 6 </ b> B corresponds to the boundary between the water channel and the swirl chamber 8.

If the connection part 4 is provided with a screw etc. like a general shower head, for example, it can connect with water piping, such as a hose, and is convenient.
On the other hand, you may form between the turning part 2 and the watering board 12 so that attachment or detachment is possible. If the swivel unit 2 and the water spray plate 12 are detachable, the water spray plate 12 can be freely exchanged according to the user's preference and the like, as will be described in detail later, the desired suction area and torsional vibration You can choose a feeling of stimulation. In addition, attachment / detachment or replacement of a mover 20 (not shown), which will be described in detail later, becomes easy.

As a mechanism for attaching and detaching the water spray plate 12, various types such as a screw fitting or a fitting mechanism between an L-shaped groove and a projection can be used as appropriate. However, in order to prevent dropping or loosening due to the swirling flow, it is desirable to use a mechanism that is fixed (tightened) by rotation in the same direction as the swirling flow.
For normal users, it is psychologically natural to rotate right when fixing, so it is advisable to provide the water inlet 6 so that the swirling flow turns right. In this way, it is easy to attach and detach, and inadvertent dropping due to swirling flow can be prevented.

FIG. 5 is a schematic cross-sectional view illustrating a state where water is supplied to the massage nozzle 1 of the present embodiment. FIG. 6 is a schematic cross-sectional view showing a state in which massage is performed by the massage nozzle 1.
Water sent from a water supply means (not shown) passes through the introduction path 5 in the connection part 4 and is introduced from the water inlet part 6 in the swirl part 2 to the swirl chamber 8. At this time, since the water inlet 6 is opened in the tangential direction of the swirl chamber 8, the water introduced into the swirl chamber 8 forms a swirl flow CF. The swirl flow CF reaches the water spout 7 while swirling along the peripheral side wall 8 </ b> W and reaches the water spray plate 12.
At this time, a negative pressure portion is generated near the center of the swirl chamber 8 due to the centrifugal force of the swirl flow CF. A force F to be pulled in (hereinafter referred to as “swing suction force”) is generated.

  On the other hand, the swirl flow that has reached the water spray plate 12 is discharged forward from the water spray holes 12a as shown by an arrow A1 in FIG. That is, the swirl component of the swirl flow CF is suppressed, and a discharge water flow that is converged as if it were a normal shower is obtained. Therefore, for example, even when the massage nozzle 1 is inadvertently opened to the atmosphere while being used in the bath water, the problem of swirling water spouting can be solved. Furthermore, this massage nozzle 1 can be used as a normal shower head when suction massage is not performed, and is very convenient.

  Next, the state of massaging will be described. As shown in FIG. 6, the swirl suction force F generated by the swirl flow CF acts on the treatment target 210 of the user by lightly contacting the massage nozzle 1. To do. As a result, it is possible to efficiently apply a suction force to the treatment site 210 and obtain a high suction massage effect.

On the other hand, a homogeneous water flow A1 discharged from the water spray hole 12a is formed between the treatment site 210 and the water spray plate 12. Furthermore, when the amount of water of the swirling flow CF exceeds the amount of water discharged from the sprinkling holes 12a, the water flow B1 overflowing from the opening 12b also forms a water film.
The to-be-processed part 210 is pressed like a donut by the water film formed by these water streams A1 and B1, and the central part is sucked into the opening 12b by the strong suction force F, and is effectively deformed in three dimensions. Get a massage. That is, the to-be-processed part 210 receives simultaneously the pressing force in the periphery and the strong suction force in the center. Furthermore, vibration is given to the to-be-processed part 210 by water flow A1 or water flow B1. Thereby, the to-be-processed part 210 deform | transforms three-dimensionally and receives the effect | action of "squeezing and unraveling" by vibration.

  Further, since the water film formed by the water streams A1 and B1 is always interposed between the water spray plate 12 and the site to be treated 210, the massage nozzle 1 is applied to the site to be treated 210 and sucked. The massage nozzle 1 can be smoothly moved as it is, and the site to be treated 210 can be sucked and massaged over a wide range.

  Here, if the ratio of the area of the opening 12b with respect to the water discharge port 7 is reduced, it becomes easy to relatively increase the amount of discharge from the water spray holes 12a provided around the opening 12b. That is, it is possible to increase the ratio of water discharged in a shower form from the water spray holes 12a and decrease the ratio of the amount of water overflowing from the openings 12b. As a result, it becomes easy to further increase the concentration of water discharged from the massage nozzle 1.

FIG. 7 is a photograph showing the result of a water discharge experiment using a massage nozzle prototyped by the present inventors. The structural parameters and operating conditions of the massage nozzle 1 shown here are as follows.

Internal diameter of swirl chamber 8 60mmφ
Length of swirl chamber 8 45mm
Size of water inlet 6 42 mm ²
Diameter of spout 7 60mmφ
Sprinkler 12 thickness 3 mm
Water spout 12a diameter 3mmφ
Number of sprinkling holes 12a 48 Diameter of opening 12b 52mmφ
Supply water volume 30 liters / minute

As shown in FIG. 7, it can be seen that the swirl component of the swirl flow is suppressed, and water is discharged in a shower shape toward the front from the sprinkling holes 12 a. In this state, when the massage nozzle 1 is lightly applied to the treatment site of the human body, the suction force by the swirling flow CF acts, and a very effective suction massage can be carried out along with the pressure and vibration effect due to water discharge. It was.

  Furthermore, since a homogeneous water film is formed by the water flow discharged from the sprinkling holes 12a and the openings 12b, the massage nozzle 1 is smoothly applied while the massage nozzle 1 is applied to the treatment site 210 and suction massage is performed. The desired range can be freely sucked and massaged.

  As described above, according to the present invention, when water is discharged in a state of being open to the atmosphere, a discharge water stream focused in a shower shape can be formed. As a result, it is possible to solve the problem that the discharged water is scattered around, and it can be used as a normal shower head. That is, according to the present invention, the shower and the suction massage can be used properly with one massage nozzle, which is very convenient.

Next, the massage nozzle provided with the guide part will be described.
FIG. 8 thru | or FIG. 10 is a schematic diagram showing the massage nozzle concerning the 2nd Embodiment of this invention. That is, FIG. 8 is a perspective view of the massage nozzle 1, FIG. 9 is a front view, and FIG. 10 is a sectional view taken along line AA in FIG. 10 is the same as FIG. 4.

  In the massage nozzle 1 of the present embodiment, a ring-shaped guide portion 10 is provided on the outer side of the spout 7 via a flange 9. A water spray plate 12 is provided at the tip of the guide portion 10. The water spray plate 12 is provided with an opening 12b at the center thereof, and a plurality of water spray holes 12a are provided around the opening 12b.

  Here, as shown in FIG. 10, if the diameter X2 of the opening 12b of the water spray plate 12 is larger than the diameter X1 of the spout 7, the suction area can be sufficiently secured, and the massage effect and the biological effect can be secured. Can be increased. Furthermore, the massage nozzle body can be formed in a compact manner, and the handling becomes easy.

  You may detachably form at least any one between the turning part 2 and the flange 9, between the flange 9 and the guide part 10, and between the guide part 10 and the watering board 12. FIG. For example, if the swivel unit 2 and the flange 9 are detachable, the flange 9 (including the guide unit 10 and the watering plate 12) can be freely replaced according to the user's preference and the like, which will be described in detail later. In this way, it is possible to select a feeling of stimulation such as a desired suction force or torsional vibration. In addition, attachment / detachment or replacement of a mover 20 (not shown), which will be described in detail later, becomes easy.

As a mechanism for attaching and detaching the flange 9, the guide portion 10, and the watering plate 12, various types such as a screw fitting or a fitting mechanism between an L-shaped groove and a protrusion can be appropriately used. However, in order to prevent dropping or loosening due to the swirling flow, it is desirable to use a mechanism that is fixed (tightened) by rotation in the same direction as the swirling flow.
Further, as described above with reference to FIGS. 1 to 4, it is psychologically natural for a normal user to rotate right when fixing, so that the water intake portion 6 is provided so that the swirling flow turns right. Good. In this way, it is easy to attach and detach, and inadvertent dropping due to swirling flow can be prevented.

FIG. 11 is a schematic cross-sectional view illustrating a state where water is supplied to the massage nozzle 1 of the present embodiment. FIG. 12 is a schematic cross-sectional view showing a state in which massage is performed by the massage nozzle 1.
That is, the water introduced from the water inlet 6 into the swirl chamber 8 forms a swirl flow CF. The swirling flow CF reaches the water discharge port 7 while swirling along the peripheral side wall 8W, and further reaches the water spray plate 12 while swirling the inner peripheral wall 10W of the guide portion 10 provided on the outer side.
Also at this time, since the negative pressure portion is generated near the center of the swirl chamber 8 and the guide portion 10 due to the centrifugal force of the swirl flow CF, the inside of the swirl chamber 8 extends from the outside of the massage nozzle 1 along the central axis of the opening 12b. A swirling suction force F is generated to try to pull in.

  On the other hand, the swirl flow that has reached the water spray plate 12 is discharged forward from the water spray holes 12a as shown by an arrow A1 in FIG. That is, the swirl component of the swirl flow CF is suppressed, and a discharge water flow that is converged as if it were a normal shower is obtained.

  In order to reliably suppress the scattering of the swirling flow CF in the present invention, first, before the swirling flow CF discharged from the water discharge port 7 reaches the opening 12b, the inner peripheral wall 10W of the guide portion 10 or the watering plate 12 is used. It is necessary to collide with. For this purpose, as shown in FIG. 10, half of the difference between the diameter of the water outlet 7 and the diameter of the opening 12 b is L1, and the water discharge A discharged from the water outlet 7 is on the surface including the water outlet 7. It is desirable to project the guide portion 10 so that the length from the spout 7 to the water spray plate 12 is equal to or greater than (L1 × tan θ), where θ is the angle formed by the operator.

  Next, the state of massaging will be described. As shown in FIG. 12, when the massage nozzle 1 is brought into light contact, the swirl suction force F generated by the swirl flow CF acts on the treatment target 210 of the user. To do. As a result, it is possible to efficiently apply a suction force to the treatment site 210 and obtain a high suction massage effect.

  Also in the present embodiment, a homogeneous water flow A1 discharged from the sprinkling holes 12a is formed between the site to be treated 210 and the sprinkling plate 12. Furthermore, when the amount of water of the swirling flow CF exceeds the amount of water discharged from the sprinkling holes 12a, the water flow B1 overflowing from the opening 12b also forms a water film. The to-be-processed part 210 is pressed like a donut by the water film formed by these water streams A1 and B1, and the central part is sucked into the opening 12b by the strong suction force F, and is effectively deformed in three dimensions. Get a massage. That is, the to-be-processed part 210 receives simultaneously the pressing force in the periphery and the strong suction force in the center. Furthermore, vibration is given to the to-be-processed part 210 by water flow A1 or water flow B1. Thereby, the to-be-processed part 210 deform | transforms three-dimensionally and receives the effect | action of "squeezing and unraveling" by vibration.

  Further, since the water film formed by the water streams A1 and B1 is always interposed between the water spray plate 12 and the site to be treated 210, the massage nozzle 1 is applied to the site to be treated 210 and sucked. The massage nozzle 1 can be smoothly moved as it is, and the site to be treated 210 can be sucked and massaged over a wide range.

  In the present embodiment, by making the area of the opening 12b larger than the spout 7, it is possible to sufficiently secure a region where the swirl suction force F acts, and to give an effective deformation to the treated portion 210. High massage effect can be obtained. Furthermore, by making the opening 12b larger than the water discharge port 7, the main body of the massage nozzle (the housing part forming the swirl chamber 8) can be made compact while ensuring the suction area determined by the opening 12b, and the effect is easy to handle. Can also be obtained.

  However, the present embodiment is not limited to this specific example. That is, the area of the water outlet 7 and the opening 12b may be substantially the same, or the area of the opening 12b may be smaller than the area of the water outlet 7. When the ratio of the area of the opening 12b to the water discharge port 7 is reduced, it becomes easy to relatively increase the amount of discharge from the water spray holes 12a provided around the opening 12b. That is, it is possible to increase the ratio of water discharged in a shower form from the water spray holes 12a and decrease the ratio of the amount of water overflowing from the openings 12b. As a result, it becomes easy to further increase the concentration of water discharged from the massage nozzle 1.

FIG. 13 is a photograph showing the results of a water discharge experiment using a massage nozzle made by the present inventor. The structural parameters and operating conditions of the massage nozzle 1 shown here are as follows.

Internal diameter of swirl chamber 8 45mmφ
Length of swirl chamber 8 45mm
Size of water inlet 6 42 mm ²
Diameter of spout 7 45mmφ
Inner diameter of guide part 10 71mmφ
Guide part 10 length 15mm
Sprinkler 12 thickness 3 mm
Water spray hole 12a diameter 4mmφ
Number of sprinkling holes 12a 40 Diameter of opening 12b 50mmφ
Supply water volume 28.6 liters / minute

First, FIG. 13A shows a state in which the guide portion 10 is removed and water is discharged from the water outlet 7. It can be seen that the swirling flow CF is scattered from the spout 7 at a wide angle and discharged to the surroundings.

  Next, FIG.13 (b) represents the state which attached the ring-shaped guide part 10 and made it discharge. It can be seen that the swirling flow CF discharged from the spout 7 collides with the guide portion 10 and is somewhat converged, and the scattering angle is slightly reduced and scattered while swirling.

  Next, FIG.13 (c) represents the state which attached the watering board 12 and made it discharge. By attaching the watering plate 12, the swirling component of the swirling flow is suppressed, and it can be seen that water is discharged in a shower shape from the watering hole 12a toward the front. In this state, when the massage nozzle 1 is lightly applied to the treatment site of the human body, the suction force by the swirling flow CF acts, and a very effective suction massage can be carried out along with the pressure and vibration effect due to water discharge. It was.

  Furthermore, since a homogeneous water film is formed by the water flow discharged from the sprinkling holes 12a and the openings 12b, the massage nozzle 1 is smoothly applied while the massage nozzle 1 is applied to the treatment site 210 and suction massage is performed. The desired range can be freely sucked and massaged.

  As described above, also in the present embodiment, when water is discharged in a state of being opened to the atmosphere, a discharge water stream that is focused in a shower shape can be formed. As a result, it is possible to solve the problem that the discharged water is scattered around, and it can be used as a normal shower head. That is, according to the present embodiment, the shower and the suction massage can be used properly by one massage nozzle, which is very convenient.

Next, the rectification effect of the water spray holes 12a provided in the massage nozzle 1 of the present embodiment will be described.
FIG. 14 is a conceptual diagram illustrating a water flow formed in the massage nozzle 1 of the present embodiment. That is, the water that has entered the swirl chamber 8 forms a swirl flow CF, reaches the sprinkling plate 12 while swirling the inner peripheral wall 10W of the guide portion 10, and is discharged from the sprinkling holes 12a. The water discharged from the sprinkling holes 12a forms a water stream that is converged in a direction substantially perpendicular to the opening 12b as indicated by the arrow A1.

  Here, in order that the water discharged from the water sprinkling hole 12a is not scattered in the turning direction as represented by the arrow A2 in the same figure but is discharged in the direction of the arrow A1, the water sprinkling hole 12a has a rectifying effect. Is needed.

  FIG. 15 is a partially enlarged cross-sectional view showing a portion of the water spray hole 12a. The swirl flow CF swirling around the inner peripheral wall 10W of the guide portion 10 is obliquely incident on the sprinkling holes 12a while maintaining the swirl component.

  Here, as shown in FIG. 15A, if the thickness T of the water spray plate 12 is small with respect to the diameter D of the water spray hole 12a, one of the swirling flow CF incident obliquely to the water spray hole 12a will be described. The part passes without colliding with the side wall of the water spray hole 12a. That is, the rectifying action on the swirling flow CF is not sufficient, and the water discharged from the water sprinkling holes 12a tends to scatter around.

  On the other hand, as shown in FIG. 15B, when the thickness T is increased with respect to the diameter D of the water spray hole 12a, all of the swirling flow CF incident obliquely to the water spray hole 12a is dispersed. , The swirl component is absorbed and released substantially vertically forward as indicated by the arrow A1. That is, the water spray hole 12a exhibits a rectifying action, and can suppress the swirl component of the swirling flow CF to be discharged as a water flow focused in the direction of the arrow A1.

  FIG. 16 is a photograph showing a part of the result of examining the rectifying effect of the water spray holes. The massage nozzle 1 represented here has the same structural parameters as those described above with reference to FIG. 13, except that the thickness of the water spray plate 12 is appropriately changed.

FIG. 16A shows the discharge water flow when the water spray plate 12 has a thickness of 1 mm. Since the water flow discharged from the sprinkling holes 12a is inclined in the swirling direction of the swirling flow, it can be seen that the discharged water flow is scattered. That is, it turns out that the turning component is not suppressed.
FIG. 16B shows the discharge water flow when the thickness of the water spray plate 12 is 2 mm. The water flow discharged from the sprinkling holes 12a is directed in a direction substantially perpendicular to the opening 12b, and the discharged water flow is converged. That is, it can be seen that the swirl component of the swirl flow is suppressed.
FIG. 16C shows the discharge water flow when the thickness of the water spray plate 12 is 3 mm. The water flow discharged from the sprinkling holes 12a is oriented in a direction perpendicular to the opening 12b, and the discharged water flow is sufficiently concentrated. That is, it turns out that the sprinkling hole 12a exhibits a sufficient rectification effect and the swirl component is suppressed.

FIG. 17 is a photograph showing a part of the result of examining the rectifying effect of the water spray holes in another massage nozzle. The massage nozzle 1 represented here has the same structural parameters as those described above with reference to FIG. 13 except for the following points.

Guide part 10 length 25 mm
Sprinkler 12 thickness 1mm, 2mm, 3mm
Diameter of opening 12b 60mmφ

FIG. 17A shows the discharge water flow when the thickness of the water spray plate 12 is 1 mm. In the same manner as described above with reference to FIG. 16 (a), the water flow discharged from the sprinkling holes 12a is inclined in the swirling direction of the swirling flow, so that the discharged water flow is scattered and the swirling component is not suppressed. I understand that. FIG. 17B shows the discharge water flow when the water spray plate 12 has a thickness of 2 mm. It can be seen that the water flow discharged from the sprinkling holes 12a converges in a direction substantially perpendicular to the opening 12b, and the swirl component of the swirl flow is suppressed.
FIG. 17C shows a discharge water flow when the thickness of the water spray plate 12 is 3 mm. The water flow discharged from the water sprinkling holes 12a is further concentrated toward the front, and it can be seen that the rectifying effect of the water sprinkling holes 12a is enhanced. Note that the discharge flow shown in FIGS. 17B and 17C has a water flow component scattered at a slightly wider angle than that shown in FIGS. 16B and 16C. The reason is considered to be due to the difference in the size of the opening 12b. This point will be described in detail later with reference to FIGS.

Next, FIG.17 (d) uses the water spray plate 12 with a thickness of 3 mm, and as shown in FIG. 18, discharge | release in the massage nozzle which connected two adjacent watering holes 12a and formed one watering hole 12L. Represents a water stream. In this case, since the opening length W of the sprinkling hole 12L as seen in the swirling direction of the swirling flow is increased, the rectifying effect on the swirling flow is greatly reduced. As a result, as shown in FIG. 17D, it can be seen that the water flow discharged from the sprinkling holes 12L is greatly inclined in the swirling direction.
In addition, although this inventor implemented the same experiment by making the length of the guide part 10 into 15 mm, the result was substantially the same as what was represented to Fig.17 (a)-(d).

  As described above, it is understood that the rectifying action of the water spray holes 12a is important in order to focus the water flow discharged from the massage nozzle 1 of the present invention. That is, as shown in FIG. 15, the larger the ratio of the thickness T of the water spray plate 12 to the opening diameter D of the water spray hole 12a (the length of the swirl flow as viewed in the swirl direction), the higher the rectifying effect is obtained. A turning component can be suppressed.

In order to suppress the swirling component of the swirling flow, a rectifying plate may be provided.
FIG. 19 is a perspective view schematically illustrating an example of a current plate.
That is, by providing the rectifying plate 14 that protrudes on the back surface side of the water spray plate 12 (side near the water discharge port 7), the swirl component of the swirl flow CF is suppressed, and the water flow that is focused in the vertical direction is discharged from the water spray holes 12a. Can be made. Such a current plate may be provided on the peripheral side wall of the guide portion 10 or the like. If the height of the rectifying plate 14 is lowered and the rectifying plate 14 is disposed at a position closer to the water spray plate 12, the swirl flow can be maintained up to a position closer to the water spray plate 12, and the object sucked from the opening 12b of the water spray plate 12 can be maintained. The effect of the swirling flow can be given to the processing portion 210 more strongly.

Next, the water flow that overflows from the opening 12b in the massage nozzle 1 of the present invention will be described.
FIG. 20 is a conceptual diagram showing a water flow formed in the massage nozzle 1 of the present invention. That is, the swirling flow CF that has reached the water spray plate 12 is suppressed in its swirling component by the rectifying action of the water sprinkling holes 12a, and is discharged in a direction substantially perpendicular to the opening 12b as indicated by the arrow A1. However, when the amount of water supplied to the nozzle exceeds the amount of water discharged from the sprinkling holes 12a, it overflows from the opening 12b as a water discharge flow B1. Since the discharged water flow B1 has a swirling component, it is scattered around as shown in FIG.
The amount of the water flow B1 discharged from the opening 12b depends on the size of the opening 12b. That is, when the opening 12b is large, the water flow B1 tends to increase.

FIG. 21 is a photograph showing changes in the water discharge flow depending on the size of the opening 12b.
The figure (a) represents the discharge | release water flow in the massage nozzle 1 whose diameter of the opening 12b is 50 mmphi. On the other hand, FIG. 7B shows the discharge water flow in the massage nozzle 1 in which the diameter of the opening 12b is 60 mmφ.
As the diameter increases, the ratio of the swirling water flow B1 discharged from the opening 12b increases. For this reason, it turns out that the scattering component contained in discharge | emission water flow increases. In the case of the massage nozzle 1 of the present invention, since the curtain of the water flow A1 discharged in the shower shape from the water spray hole 12a is formed, the water flow B1 having the scattering component tends to be blocked by the curtain of the water flow A1. . And if water flow B1 becomes strong, the curtain of water flow A1 will be pierced and the discharged water discharge flow will be formed.

However, in the present invention, it is not necessary to completely suppress the swirling water flow B1, and it can be determined as appropriate according to the characteristics and applications required of the massage nozzle. That is, as described above with reference to FIG. 12, the water flow B <b> 1 discharged from the opening 12 b gives physical stimulation such as “twist” or “vibration” due to the swirl component to the processing target 210. As a result, it is possible to further enhance the massage effect. Furthermore, the water flow B1 forms a homogeneous water film on the surface of the water spray plate 12, and protects the surface of the treated portion 210. As a result, there is also an effect that the massage nozzle 1 can be smoothly moved while the massage nozzle 1 is applied and sucked, and a wide range of suction massage can be performed freely.
That is, if the water flow B1 discharged from the opening 12b is maintained to such an extent that the water discharge does not scatter widely, a higher massage effect may be obtained.

  As one of means for suppressing the water flow B1 discharged from the opening 12b, there is a method of providing a peripheral protrusion on the back side of the water spray plate 12.

  FIG. 22 is a schematic cross-sectional view showing a massage nozzle having a peripheral protrusion on the water spray plate 12. Moreover, FIG. 23 is the perspective view which looked at the watering board 12 of this massage nozzle 1 from the back surface side.

  In this specific example, a peripheral protrusion 15 that protrudes from the periphery of the opening 12b in the direction of the spout 7 is provided. By providing such a peripheral protrusion 15, it is possible to suppress the swirling flow that has reached the water spray plate 12 from overflowing from the opening 12 b. In other words, the peripheral protrusion 15 serves as a “weir” for preventing the swirling flow from overflowing from the opening 12b.

FIG. 24 is a photograph showing the effect of the peripheral protrusion 15.
The massage nozzle 1 used here has the same structural parameters as those described above with reference to FIG. 13 except that the length of the guide portion 10 is 25 mm and the diameter of the opening 12b is 58 mmφ.

FIG. 24A shows the discharge water flow when the peripheral protrusion 15 is not provided. A slightly scattered water flow component is observed mixed with the water flow discharged in a shower form from the water spray holes 12a. This is considered to be a component of the water stream B1 that breaks through the curtain of the water stream A1.
FIG. 24B shows the discharge water flow when the peripheral protrusion 15 having a rising height of 2.5 mm from the back surface of the water spray plate 12 is provided. It can be seen that by providing the peripheral protrusion 15, the scattered components contained in the discharged water flow are clearly reduced. That is, the swirl water flow B1 discharged from the opening 12b is suppressed.

  FIG. 24C shows the discharge water flow when the peripheral protrusion 15 having a rising height of 5 mm is provided. It can be seen that by increasing the height of the peripheral protrusion 15, the scattering component contained in the discharged water flow is further suppressed. That is, the swirl water flow B1 discharged from the opening 12b is further suppressed.

  As described above, according to the present invention, the balance between the water flow A1 discharged from the sprinkling hole 12a and the water flow B1 discharged from the opening 12b is adjusted by adjusting the presence or height of the peripheral protrusion 15 or the height thereof. Can be adjusted. Therefore, for example, when it is desired to suppress the scattering of the discharged water flow as much as possible in the open state, the height of the peripheral protrusion 15 may be increased to suppress the water flow B1 discharged from the opening 12b. On the other hand, in suction massage, when it is desired to increase the effect of loosening such as “twisting” and “vibration” by the swirling flow, the height of the peripheral protrusion 15 is reduced or not provided, so that the water flow B1 is reduced. Increase it.

Next, a massage nozzle in which a mover is provided inside the guide part or swirl chamber will be described.
FIG. 25 is a front view of the massage nozzle according to the embodiment of the present invention.
Moreover, FIG.26 and FIG.27 is a perspective view of the massage nozzle of this embodiment, respectively. FIG. 28 is a perspective view showing a mover provided in the massage nozzle of the present embodiment, and FIGS. 29 to 31 are cross-sectional views taken along line AA in FIG. In these drawings, elements similar to those described above with reference to FIGS. 1 to 24 are denoted by the same reference numerals, and detailed description thereof is omitted.

In this specific example, a mover 20 is provided in the guide portion 10. The mover 20 is not fixed, and can move freely in a space defined by the flange 9, the guide portion 10, and the water spray plate 12.
Note that the present invention is not limited to this specific example, and the movable element 20 can be similarly provided in a massage nozzle not provided with the guide portion 10 as described above with reference to FIGS. That is, as shown in FIG. 1 to FIG. 7, when the water spray plate 12 is provided at the tip of the spout 7, by providing the movable element 20 in the swirl chamber 8, various kinds of details described below are provided. The effect can be obtained similarly.
As shown in FIG. 28, the mover 20 includes a substantially disk-shaped stopper 20c having an opening at the center and a cylindrical ring portion 20a rising from the opening end. The stopper 20c is formed to be slightly larger than the opening 12b of the water spray plate 12, and does not come out of the opening 12b during normal handling. Moreover, the outer dimension of the stopper 20c is defined so as not to substantially block the water spray hole 12a.

  Furthermore, as shown in FIG. 30, if the maximum outer dimension X3 of the stopper 20c is larger than the diameter X2 of the opening 12b of the water spray plate, the mover 20 may drop out of the guide portion 10. It is easy to handle.

  The use state of the massage nozzle 1 of the present embodiment will be described with reference to FIG. When water is supplied from a water supply means (not shown) to the massage nozzle 1, a swirl flow CF is formed in the swirl chamber 8. The swirling flow CF swirls along the inner peripheral wall 10 </ b> W of the guide portion 10 from the water outlet 7 and reaches the watering plate 12. At this time, the mover 20 comes into contact with the back surface of the water spray plate 12 due to the pressure of the swirling flow CF, and the cylindrical ring portion 20 a protrudes outward from the opening 12 b of the water spray plate 12. At this time, the movable element 20 receives a substantially uniform pressing force toward the center from the inner peripheral wall 10W of the guide portion by the swirling flow CF, and is disposed substantially coaxially with the swirling axis Z of the swirling flow CF. That is, the mover 20 abuts against the back surface of the water spray plate 12 at a substantially equidistant position when viewed from the inner peripheral wall 10W of the guide portion.

  At this time, the stopper 20c does not substantially block the water spray hole 12a provided in the water spray plate 12, and the swirling flow CF that has reached the water spray plate 12 is discharged from the water spray hole 12a in a shower shape. And by providing the mover 20, the opening 12b of the water spray plate can be made substantially small, and the scattering of the swirling flow can be more efficiently suppressed. That is, in the state shown in FIG. 29, the size of the opening of the watering plate is equal to the size of the opening of the stopper 20c. That is, the opening of the watering plate can be reduced. As a result, it is possible to enhance the effect of the “dam” that blocks the scattering of the swirling flow, and as described above with reference to FIG. 21, the scattering of water from the opening of the water spray plate (the opening of the ring portion 20a) can be more reliably suppressed. .

Furthermore, in the state where the mover 20 is arranged as shown in FIG. 29, the thickness of the stopper 20c has the same effect as the peripheral protrusion 15 described above with reference to FIGS.
On the other hand, the swirling water flow that overflows the opening 12b of the water spray plate 12 is released in the direction of the arrow C1 in FIG. 29, but collides with the inner wall of the ring portion 20a to suppress the swirling component, so that a wide angle splash is generated. Can be prevented.
As described above, when the mover 20 is provided, scattering of the swirling flow from the opening 12b of the water spray plate can be more effectively suppressed in the open water discharge state as shown in FIG.

  In this state, a negative pressure region due to the swirling flow CF is formed inside the ring portion 20a. Therefore, when the part to be processed 210 is brought closer, as shown in FIG. 30, the part 210 is sucked into the ring portion 20a and massage can be performed. At this time, a water film is formed between the treated portion 210 and the tip of the ring portion 20a by the water flow C1 overflowing from the inside of the ring portion 20a, and the treated portion 210 is protected. Moreover, the to-be-processed site | part 210 receives pressing force with the water flow A1 discharge | released from the watering hole 12a provided in the outer side, and a massage effect is further accelerated | stimulated.

Further, when the user slightly increases the force of pressing the massage nozzle 1, as shown in FIG. 31, the mover 20 moves backward against the pressure of the swirling flow CF, and is wider by the opening 12 b of the water spray plate 12. The site to be treated 210 can be aspirated. At this time, as described above with reference to FIG. 12, a pressing force acts on the processing target 210 by the water streams A1 and B1, and the processing target 210 is protected by the water film formed by these water flows.
That is, in the state where the mover 20 is pushed into the guide portion 10 (or the swirl chamber 8), the area of the opening of the water spray plate can be increased, and the suction effect (biological effect) can be enhanced. At the same time, since the amount of water (B1) overflowing from the opening of the water spray plate increases, the effect of forming a water film on the front surface of the water spray plate 12 increases, and the mobility of the nozzle can be improved. As can be seen from a comparison with the state shown in FIG. 29, when the mover 20 is provided, the opening of the watering plate can be reduced in the open water discharge state, and the opening of the watering plate can be increased in the suction massage state, depending on the use state. Thus, these states can be automatically switched.

  At this time, the mover 20 rotates and vibrates due to the swirling action of the swirling flow CF, and gives a physical stimulus to the processing target 210. For this reason, the to-be-processed part 210 receives the stimulus from the needle | mover 20 in addition to the "twist" and "vibration" by the turning flow CF, and the massage effect is further accelerated | stimulated.

FIG. 32 is a photograph showing the scattering prevention effect by the mover 20.
The massage nozzle used here has the same structural parameters as those described above with reference to FIG. 13 except that the length of the guide portion 10 is 25 mm and the diameter of the opening 12b of the water spray plate 12 is 60 mmφ. . Here, the diameter of the stopper 20c of the mover 20 is 62 mmφ, the opening diameter is 44 mmφ, the outer diameter of the ring portion 20 a is 48 mmφ, and the inner diameter is 44 mmφ.

  FIG. 32A shows a case where the mover 20 is not provided. At this time, as described above with reference to FIG. 21B, it can be seen that there are many scattered components due to the swirling water flow discharged from the opening 12 b of the water spray plate 12.

  FIG. 32B shows a case where the mover 20 is provided. It can be seen that by providing the mover 20, the swirl component of the swirling water flow discharged from the opening 12b of the water spray plate 12 is suppressed, and a converged discharged water flow with little scattering is obtained. In this state, when the massage nozzle 1 was brought close to the site to be treated, effective suction massage could be performed as described above with reference to FIG. 30 or FIG.

  FIG. 33 is a schematic cross-sectional view illustrating a modified example of the massage nozzle having the mover 20. That is, in the present modification, the mover 20 is provided, and the peripheral protrusion 15 is provided on the back surface side of the watering plate 12. As described above with reference to FIGS. 22 to 24, by providing the peripheral protrusion 15, the balance between the water flow A1 discharged from the water spray hole 12a and the water flow B1 discharged from the opening 12b of the water spray plate 12 can be adjusted. That is, it is possible to appropriately balance the prevention of scattering in the open water discharge state and the effect of the swirling flow in the suction massage.

  Further, by further providing the mover 20, it is possible to achieve both prevention of scattering and promotion of the massage effect in suction massage at a higher level.

  In the case where the mover 20 is provided, in order to surely suppress the scattering of the swirling flow CF, first, the swirling flow CF discharged from the water discharge port 7 needs to collide with the stopper 20c. is there. For this purpose, as shown in FIG. 33, half of the difference between the diameter of the water discharge port 7 and the diameter of the opening of the stopper 20 c is L2, and the surface of the water discharge A discharged from the water discharge port 7 includes the water discharge port 7. It is desirable to project the guide portion 10 so that the length from the water outlet to the stopper 20c is equal to or greater than (L2 × tan θ) when the angle formed with respect to is θ is θ. . Here, the “open water discharge state” refers to a state in which the swirl flow is discharged without applying the massage nozzle 1 to the site to be treated. At this time, the stopper 20c of the mover 20 is It is substantially coaxial and is in contact with the back surface or peripheral protrusion 15 of the water spray plate 12.

  25 to 33 exemplify the ring portion 20a of the mover 20 having a substantially cylindrical shape, the present invention is not limited to this. That is, the ring portion 20a may be formed in an “expanded shape” in which the opening expands toward the tip, or conversely, may be formed in a “tip-drawer shape” in which the opening narrows toward the tip. When the ring portion 20a is formed in an “expanded shape”, the opening of the stopper 20c is smaller than the opening at the tip of the ring portion 20a. On the other hand, in the case where the ring portion 20c is formed in a “tip-drawer shape”, the opening of the stopper 20c is larger than the opening at the tip of the ring portion 20a. In any of these cases, it is desirable to determine the relational expression based on the opening of the stopper 20c.

  FIG. 34 is a schematic cross-sectional view illustrating a second modification of the massage nozzle provided with the mover 20. That is, in this modification, the mover 20 is urged toward the water spray plate 12 by the spring 18. If it does in this way, the mover 20 will be contact | abutted and hold | maintained at the back surface of the watering board 12 in the state positioned in the center so that the watering hole 12a may not be plugged up in an unloaded state. That is, by providing the spring 18, the movable element 20 can be more reliably brought into contact with the water spray plate 12 during open water discharge, and the rectifying effect of the movable element 20 can be more reliably obtained.

  In addition, when carrying out suction massage, it is possible to perform suction massage through the ring portion 20a as shown in FIG. 30 by lightly touching the site to be treated. The child 20 retreats against the spring 18 and the pressure of the swirling flow CF, and as shown in FIG. 31, a wide range of suction massage is possible through the opening 12b of the water spray plate 12.

  In the present invention, instead of urging the mover 20 by the spring 18, for example, the position of the mover 20 may be adjustable by a mechanical vertical adjustment mechanism. That is, the mover 20 is provided in the guide portion 10 and the position thereof can be adjusted as appropriate by a lever, a button, or the like. The state shown in FIGS. 29 to 30, the state shown in FIG. Can be maintained. Moreover, it is good to provide the mechanism positioned in the center vicinity so that the stopper 20c may not block the water spray hole 12a in the state which the needle | mover 20 contact | abutted to the water spray plate 12. FIG.

Next, the result of measuring the suction pressure of the massage nozzle 1 of the present invention will be described.
FIGS. 35 to 39 and FIGS. 40 to 44 are schematic views showing the two types of massage nozzles 1 that were experimentally evaluated by the inventors.
35 is a perspective view of the massage nozzle 1 (sample 1), FIG. 36 is a front view, FIG. 37 is a top view, FIG. 38 is a side view, and FIG. 39 (a) is AA in FIG. It is line sectional drawing and the figure (b) is a mimetic diagram showing the shape of the water intake part 6.
40 is a perspective view of the massage nozzle 1 (sample 2), FIG. 41 is a front view, FIG. 42 is a top view, FIG. 43 is a side view, and FIG. 44 is a cross-sectional view taken along line AA in FIG. It is.
In these drawings, elements similar to those described above with reference to FIGS. 1 to 34 are denoted by the same reference numerals, and detailed description thereof is omitted.

The massage nozzle of Sample 1 shown in FIGS. 35 to 39 has the mover 20, and the massage nozzle of Sample 2 shown in FIGS. 40 to 44 does not have the mover.
In the massage nozzles of Samples 1 and 2, the nozzle body, that is, the swivel unit 2 and the connection unit 4 are integrally formed of an opaque resin. Moreover, the flange 9, the guide part 10, and the watering board 12 are integrally formed with transparent resin, and are being fixed with the adhesive agent with respect to the main body (swivel part 2).

  On the other hand, the mover 20 of the massage nozzle of the sample 1 is made of rubber. As shown in the size of each part in FIG. 39, the inner diameter of the opening 12b of the water spray plate 12 is 58 millimeters, whereas the outer dimension of the stopper 20c of the mover is 64 millimeters. By forming the mover 20 from rubber, it can be easily elastically deformed and inserted into and removed from the guide portion 10 through the opening 12b.

  Further, as will be described later with reference to FIG. 48, the water inlet 6 has a width (3.8) in a direction perpendicular to the swirling axis of the swirling flow CF when viewed from the direction facing the water inflow direction. The width in the direction parallel to the pivot axis (11.8 millimeters) is larger than that of millimeters). With such a flat shape, the swirl flow CF can be developed efficiently. In addition, a rubber anti-slip 2S is provided on the back side of the swivel unit 2 so as to be easily held by the user and to be familiar with the hand.

On the other hand, the watering plate 12 is provided with 40 watering holes 12a having a diameter of 4 millimeters. The diameter (PCD) of the circle formed by the center of these watering holes 12a is 66 millimeters. As can be seen from FIG. 39, when the mover 20 is at the center of the opening 12b of the water spray plate 12, the stopper 20c of the mover overlaps the water spray hole 12a by about 1 millimeter.
When the water discharge state was confirmed in the massage nozzle of Sample 1 configured in this way, good shower water discharge was realized. That is, it has been found that even if the stopper 20c of the mover and the water spray hole 12a overlap somewhat, the water spray hole 12a is not substantially blocked. By forming the mover stopper 20c to be large, the mover 20 can be reliably pushed forward by the water flow of the swirling flow CF in a state where the massage nozzle 1 is discharged in the atmosphere (open discharge state).

Further, even when the center axis of the mover 20 is deviated from the turning axis, a “gap” is unlikely to be generated between the stopper 20 c and the opening 12 b of the water spray plate 12. That is, the effect of the “dam” by the stopper 20c can be ensured. As a result, it is possible to reliably obtain a rectifying effect by discharging water from the water spray holes 12a.
In addition, since the mover receives the force ahead of the nozzle more reliably during massage, vibration stimulation to the site to be processed can be made more reliable.

  In addition, if the mover stopper 20c is formed larger, a part of the mover stopper 20c tends to affect the swirling flow CF. That is, the flow of the swirl flow CF is changed by the movement of the mover 20, and the suction region can be dynamically changed. That is, the distribution of the negative pressure region (suction region) changes according to the movement of the mover 20, and the massage effect is further enhanced by the vibration effect, the twist effect, and the like.

The inventor measured the suction pressure of these massage nozzles.
FIG. 45 is a schematic diagram showing a measurement method performed by the present inventors.
That is, a pressure receiving plate 300 provided with a small hole 300a was disposed in front of the massage nozzle 1, and the pressure -P in the small hole was measured with a manometer. The measurement was performed with the massage nozzle 1 submerged in water, and the distance between the front surface of the water spray plate 12 and the pressure receiving plate 300 was 7 millimeters for both Sample 1 and Sample 2. Further, the pressure receiving plate 300 was 90 mm square, and the small hole 300a was 2 mm in diameter. In this measurement, the mover 20 was rotated in the guide portion 10 as shown in FIG.
The small hole 300 a is provided at the center of the pressure receiving plate 300 and is arranged so as to correspond to the central axis of the massage nozzle 1. In this measurement, the flow rate Q and the pressure P supplied to the massage nozzle 1 were measured.

  FIG. 46 is a PQ graph showing the relationship between the flow rate Q and the pressure P supplied to each sample. At this time, even if the water spray plate 12 was removed and the guide portion 10 was exposed, or the guide portion 10 and the flange 9 were removed and the water outlet 7 was exposed, the PQ graphs were almost the same. That is, it can be seen that the pressure loss hardly increases even if the flange 9, the guide portion 10, the water spray plate 12, the movable element 20 and the like are added. This is considered to mean that most of the pressure loss in the massage nozzle 1 occurs in the formation of the swirl flow CF in the swirl chamber 8, and the efficiency due to the provision of the watering plate 12 and the movable element 20. It means that the drop is very small.

FIG. 47 is a graph showing the suction pressure measured in the small hole 300a of the pressure receiving plate 300. FIG. In this graph, the triangle and square plots are actual measurement values of the respective samples, and the curve represents the actual measurement value by quadratic curve approximation.
In the case of the massage nozzles of Samples 1 and 2, a suction pressure of 3000 to 9000 Pascals was obtained at a flow rate of 17 to 28 liters per minute, and a good suction feeling could be obtained.
As a result of simultaneous experience evaluation by a plurality of subjects, when the flow rate is less than 10 liters per minute, the mover 20 moves but the feeling of stimulation is poor. On the other hand, when the flow rate is 43 liters or more per minute, the mover 20 moves. There was a tendency that the stimulation by the rotational shear force became stronger. Summing up the results of the sensation evaluation of many subjects, moderate stimulation was often obtained when the flow rate was 15 liters per minute or more. In addition, it is considered that a water pump of about 50 to 200 watts is often used in ordinary home use. From this viewpoint, the upper limit of the flow rate is about 30 liters per minute.

  High-power water pumps are somewhat unsuitable for home use due to slightly increased noise, but can be used in esthetic salons and medical applications, and have a strong massage effect due to a large flow rate and high It is possible to give a biological effect, a strong stimulation, and the like.

  Next, the shape of the water inlet 6 of the massage nozzle 1 of the present invention will be described. That is, in order to obtain a strong suction force in the present invention, it is important to efficiently develop the swirl flow CF along the peripheral side wall 8W in the swirl chamber 8. For this purpose, a method of forming the opening of the water inlet 6 in a flat shape is effective.

  FIG. 48 is a schematic diagram showing the massage nozzle 1 formed by this method.

That is, FIG. 4A is a cross-sectional view similar to that shown in FIG. 4, and FIG. 4B is a cross-sectional view taken along the line DD.
As shown in FIG. 48, in the case of this massage nozzle, the width W2 of the swirling flow CF in the direction perpendicular to the swirling axis Z when viewed from the direction facing the water entering direction (arrow S) with respect to the swirling chamber 8. The width W1 in the direction parallel to the turning axis Z is formed to be larger than that. In other words, the water inlet direction with respect to the swirl chamber 8 is greater than the width W2 of the water inlet section 6 along the direction perpendicular to the water inlet direction (arrow S) into the swirl chamber 8 and perpendicular to the swirl axis Z of the swirl flow CF. The width W1 of the water inlet 6 along the direction perpendicular to the swirl flow and parallel to the swirl axis Z is formed to be larger. By forming the water inlet 6 in this manner, a swirl flow can be efficiently developed in the swirl chamber 8. As a result, a uniform and strong swirl flow CF is formed from the peripheral side wall 8W of the swirl chamber along the inner peripheral wall 10W of the guide portion and discharged from the sprinkling holes 12a, thereby preventing the discharge water flow from being scattered efficiently and efficiently. A suction pressure is obtained. Further, a swirl flow CF along the peripheral wall is formed, and water discharge from the opening 12b of the water spray plate and the opening of the mover 20 is reduced, thereby improving the rectifying effect.

  Here, it is not necessary to maintain the relationship between the above-described widths W1 and W2 over the entire water inlet 6, and the relationship between the above-described widths W1 and W2 only needs to be established at only a part thereof. . For example, in view of the degree of influence on the swirling flow, it is desirable that the relationship between the widths W1 and W2 described above be established at or near the water inlet 6B. In order to reduce pressure loss, the water inlet 6A is provided as the inlet 5 It is desirable to communicate smoothly from water to the water inlet 6B.

  Next, the shape of the swirl chamber 8 of the massage nozzle 1 of the present invention will be described. In the present invention, the swirl chamber 8 can have a single substantially cylindrical space that opens straight toward the water outlet 7. That is, in the massage nozzle 1 illustrated in FIG. 3, FIG. 48 and the like, the inner diameter of the swirl chamber 8 and the opening diameter of the water discharge port 7 are substantially the same, Not provided. If such a substantially single cylindrical shape is adopted as the form of the swirl chamber 8, the pressure loss of the water flow can be reduced as compared with the case where the “squeezing part” is provided in the vicinity of the water discharge port 7. The flow rate obtained with respect to the pressure can be increased. As a result, the flow rate of the swirling flow CF can be increased and a strong suction pressing action can be obtained.

  Furthermore, such a single cylindrical swirl chamber is very easy to manufacture and can reduce costs. When the suction massage nozzle 1 of this specific example is formed by a resin injection molding technique (injection molding) or the like, the shape of the swirl chamber 8 may be provided with a “taper”. That is, in order to mold the resin in the mold and then smoothly pull out the mold protrusion for forming the inner space of the swirl chamber 8, the swirl chamber 8 is not uniform in inner diameter but slightly toward the water outlet 7. It is desirable that the inner diameter be increased. The present invention includes those having such a tapered swirl chamber 8.

  On the other hand, in the present invention, a part or the whole of the swirl chamber 8 may be conical. For example, in the vicinity of the water discharge port of the swirl chamber 8, it is possible to provide a “throttle portion” whose inner diameter gradually decreases.

FIG. 49 is a schematic diagram showing a specific example in which the “throttle portion” is provided on the flange 9.
In the case of the specific example shown in FIG. 49A, a narrowed portion 8 </ b> N whose inner diameter gradually decreases toward the water discharge port 7 is provided in the flange 9 portion.
On the other hand, in the specific example shown in FIG. 49 (b), the narrowed portion 8 </ b> N is formed longer than the plate thickness of the flange 9.

Next, the modification of the water intake part 6 of the massage nozzle 1 of this invention is demonstrated.
FIG. 50 is a schematic cross-sectional view showing a modified example of the water inlet 6 of the massage nozzle of the present invention. That is, this figure is a cross-sectional view showing the water inlet 6 of the massage nozzle, as in FIG. In the massage nozzle of this specific example, a pair of water intake portions 6 are provided. Each of these water inlets 6 introduces water from an introduction passage 5 formed in an annular shape outside the swirl chamber 8 in a direction substantially tangential to the peripheral side wall 8W. By providing a plurality of water inlets 6 in this manner, even when the total water inlet area is the same, the center position of the opening of each water inlet 6 can be arranged away from the swirl axis of the swirl flow CF. it can. In this way, the swirl flow CF can be efficiently formed. Further, when the plurality of water intake portions 6 are evenly arranged on the peripheral wall of the peripheral side wall 8W, the swirl axis of the swirl flow CF can be matched with the central axis of the swirl chamber 8. Therefore, a swirl flow CF is formed along the peripheral wall, and water discharge from the opening 12b of the water spray plate and the opening of the movable element 20 is reduced. Further, the distribution of the swirl flow CF becomes more uniform, and water discharge from the water spray holes 12a is reduced. Since it becomes more uniform, the rectification effect is improved.

The massage nozzle of the present invention has been described above with reference to FIGS.
In the present invention, in any of these massage nozzles, at least a part can be formed of a transparent material. That is, at least one of the guide part 10, the turning part 2, the flange 9, the watering plate 12, and the movable element 20 can be formed of a transparent material. Moreover, not all of these elements may be formed of a transparent material, but only a part thereof may be formed of a transparent material.

  For example, by forming at least a part of the guide portion 10 with a transparent material, the suction state of the site to be processed 210 can be reliably confirmed visually.

  FIG. 51 is a schematic diagram illustrating a massage nozzle in which the guide unit 10 and the movable element 20 provided therein are formed of a transparent material. In the case of this specific example, the tip of the processing target 210 sucked into the guide part 10 and the movable element 20 can be observed from the outside with the naked eye.

  According to the results of the inventor's trial examination, when the guide portion 10 is made transparent, in many cases, the subject confirms with the naked eye that a displacement much larger than the feeling received from the skin is obtained. There were many surprises. That is, when suction massage is performed using the massage nozzle of the present invention, the actual amount of displacement observed visually is often much larger than the sensation received from the skin. By confirming this displacement with the naked eye, it is possible to obtain a sense of expectation, a sense of reliability, a sense of security, etc., and to enhance the massage effect and other various biological effects.

  Furthermore, since the movement of the mover 20 can be visually confirmed, the movement state can be confirmed, and a sense of expectation, reliability, and a sense of security can be obtained, and a massage effect and various other biological effects can be enhanced. It becomes.

  In this case, the entire guide unit 10 does not have to be transparent, as long as the deformation state of the site to be processed can be confirmed with the naked eye. Further, the material does not necessarily need to be colorless and transparent, and may be colored transparent or translucent as long as the inside can be identified with the naked eye. On the other hand, when the flange 9 and the water spray plate 12 are formed of a transparent material together with the guide portion 10, the above-described confirmation effect is further increased.

  Moreover, only a part of the swivel unit 2 (for example, a side surface or a bottom surface) may be formed of a transparent material. As a result, the state of the skin drawn into the swirl chamber from the spout can be visually confirmed, and the deformation state of the skin can be visually observed from an oblique direction or the front in addition to the visual observation from the lateral direction. Further increase.

  Next, the massage device of the present invention using these massage nozzles will be described.

  That is, by combining the massage nozzle of the present invention described above with reference to FIGS. 1 to 51 with a water supply means or the like, a massage device capable of performing suction massage is realized.

FIG.52 and FIG.53 is the schematic diagram which looked at the 1st Example of the massage apparatus of this invention from the diagonal front side and the diagonal back side, respectively.
FIG. 54 is a block diagram showing the main configuration of the massage apparatus.

  That is, when the massage device of the present embodiment is viewed from the outside, it has a housing 70, a flexible hose 30 extending from the front surface, and the massage nozzle 1 provided at the tip thereof. The housing 70 is appropriately provided with a power switch 72, a flow rate adjusting valve 74, a water intake 76, a holding hole 78, a power cord 80, and the like. A water supply means 50 is accommodated in the housing 70. The water supply means 50 incorporates, for example, an electric water supply pump that has been subjected to water resistance treatment, and sends water (hot water) taken from the water intake 76 to the massage nozzle 1 via the flexible hose 30. For example, the water pump may be supplied with AC or DC power from the outside of the housing 70, or may be supplied with a power source such as a rechargeable battery built in the housing 70. In any case, a predetermined water-resistant treatment is appropriately performed so that it can be used safely by being immersed in hot water in the bathtub.

On the other hand, the massage nozzle 1 has an appearance similar to a shower head as illustrated in FIG. The massage nozzle 1 </ b> A shown in the figure has a shape suitable for use with the vicinity of the tip as a “wasking”. The massage nozzle 1B has a shape suitable for holding and using its root portion like a normal shower head.
As described above with reference to FIGS. 1 to 51, these massage nozzles 1 (1A, 1B) can discharge a water stream focused in a shower shape from the water spray holes 12a in the open state, thereby preventing spattering of the discharged water.

  FIG. 55 is a schematic diagram for explaining a use state of the massage apparatus of the present embodiment. That is, the user 200 can install the massage device of the present invention in the bathtub 100 with hot water 110 and operate the massage nozzle 1 while sitting on the housing 70. At this time, as described above with reference to FIG. 6 and FIG. 30, the front surface of the water spray plate 12 or the tip of the movable element 20 is covered with the water film formed by the water flows A <b> 1 and B <b> 1. The surface is always protected by a homogeneous water film. For this reason, the human body does not receive excessive frictional resistance from the massage nozzle 1, has no unpleasant irritation, and has an excellent feeling of use. When used in a state of being immersed in water (hot water) in the bathtub, it is possible to suppress the formation of an air layer (cavity) in the swirl chamber 8 that lowers the suction force, which is more effective. Moreover, the water-saving effect is also high at the point which circulates and uses the hot water 110 in the bathtub 100. FIG.

  According to the massage apparatus of the present embodiment, as described above with reference to FIGS. 1 to 51, a shower-like converged discharge water flow is formed in the open state. Therefore, even if the massage nozzle 1 is inadvertently exposed to the atmosphere during suction massage in the hot water 110 of the bathtub as shown in FIG. 55, the discharged water does not scatter around and the discomfort is eliminated. And a comfortable suction massage becomes possible. Furthermore, the massage nozzle 1 can be used as a normal shower head, which is very convenient.

  Further, in the case of the present embodiment, the massage nozzle 1 is connected to the housing 70 by the flexible hose 30, so that the massage nozzle 1 can be flexibly and freely applied to any part of the user's body to be treated. You can hit it.

  Further, according to the present embodiment, the user 200 can operate the massage nozzle 1 while sitting on the compact casing 70. As a result, the user 200 can always perform a suction massage in a relaxed state. Furthermore, even in the case of sucking and massaging the upper body, for example, the second arm from the armpit, it is possible to operate the massage nozzle 1 while being immersed in the hot water 110 of the bathtub. In addition, the hips and back of the thighs that are difficult to treat will float from the bottom of the bathtub due to sitting, creating a space for treatment, and even the lower body, for example, the back of the hips and thighs, will be massaged evenly. be able to. Therefore, it is possible to promote the discharge of the waste products and improve the cellulite to normal fats by loosening the “cellulite (scraps of fat and fat)” that is easily attached to these parts. As a result, the “tightening effect” of the human body is obtained.

FIG. 56 is a schematic view showing a second embodiment of the massage device of the present invention. In this figure, the same elements as those described above with reference to FIGS. 1 to 55 are denoted by the same reference numerals, and detailed description thereof is omitted.
The massage device of the present embodiment is also a massage device housed in the housing 70 and can be used by being installed on the edge of the bathtub 100 in the bathroom, that is, the “apron”. That is, a water supply means 50 such as a pump is built in the housing 70, and water (hot water) in the bathtub is drawn up through the intake pipe 152 and sent to the switching valve 140. The switching valve 140 can switch the water supply path to either the nozzle pipe 154 or the bubble flow discharge pipe 156. The water sent to the nozzle pipe 154 is sent to the massage nozzle 1 and suction massage can be performed. On the other hand, when water is sent to the bubbling flow discharge pipe 156, air is mixed through the intake cock 170, and a bubbling bath can be carried out.

  By adopting such a configuration, it becomes possible to use the bubble bath and the suction massage at the same time in the capacity range of the water supply means 50, and the comfort is increased. Further, by appropriately switching between water supply to the bubble flow discharge pipe 156 and water supply to the massage nozzle 1, the bubble bath and the suction massage can be switched according to the preference of the user.

  Then, as described above with reference to FIGS. 1 to 51, a shower-like concentrated discharge water flow is formed in the open state. Therefore, even if the massage nozzle 1 is inadvertently exposed to the atmosphere during suction massage in the hot water (water) in the bathtub 100, the discharged water does not scatter around and is uncomfortable. This makes it possible to perform a comfortable suction massage. Furthermore, the massage nozzle 1 can be used as a normal shower head, which is very convenient.

Therefore, it is possible to receive a suction and pressure massage. At this time, the massage nozzle 1 may be submerged or may be exposed above hot water. However, when the massage nozzle 1 is submerged, air is not taken into the swirl chamber 8, so that a stronger suction massage can be received.
On the other hand, as shown in FIG. 57 (b), the massage nozzle 1 can be removed from the nozzle housing 120 and used. In the present embodiment, since the massage nozzle 1 is connected by the flexible hose 30, the user can move the massage nozzle 1 to a free position and use it by hitting the treatment site.

  Also in this embodiment, hot water (water) in the bathtub 100 is supplied to the massage nozzle 1 by the water supply means 50. That is, the water-saving effect is high in that the hot water in the bathtub 100 is circulated and used. As described above with reference to FIGS. 1 to 51, according to the massage nozzle 1 of the present invention, a shower-like converged discharge water flow is formed in the open state. Therefore, even when the massage nozzle 1 is inadvertently exposed to the atmosphere during the suction massage in the hot water of the bathtub 100, the discharged water does not scatter to the surroundings, and uncomfortable feeling is eliminated and comfortable. Suction massage is possible. Furthermore, the massage nozzle 1 can be used as a normal shower head, which is very convenient.
