DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on an example of an embodiment. The body hair treatment apparatus in the illustrated example is an electric razor that cuts body hair (hair), and includes a body hair processing unit 6 that performs body hair cutting processing. Main body 1, a cover 2 detachably or detachably disposed on the outer surface of the main body 1, a treatment agent container 3 filled with a treatment agent for body hair treatment, and a pressure applied to the treatment agent container 3. The pressurizing unit 4 discharges the treatment agent from the discharge unit 5 located in the vicinity of the hair processing unit 6 of the main body 1.
[0011]
First, the main body 1 will be described. The main body 1 is a cylindrical housing 10 in which a driving motor 11 and a battery 12 as a power source are housed via a chassis 18, and the hair processing unit 6 located at the upper end thereof. Is provided with two sets of net blades 61 composed of a net-shaped outer blade and an inner blade that is reciprocally driven, and one set of slit blades 62 composed of a slit-shaped outer blade and an inner blade that is reciprocally driven. Each of these inner blades is connected to a driver 14 for converting the rotation of the motor 11 into a reciprocating motion and a driver 15 for a slit blade. In the figure, 19 is a switch for turning on and off the motor 11.
[0012]
A cover 2 is detachably disposed on one surface of the main body 1, a discharge unit 5 is disposed in an upper part of a space between the main body 1 and the cover 2, and a pressurizing unit 4 and a processing agent container are disposed in the lower part. 3 are arranged.
[0013]
The treatment agent container 3 here is formed as a vertically long bag having flexibility, and has a connection port 30 at its upper end.
[0014]
Further, the pressurizing means 4 in this example uses a pressing plate 40 that sandwiches the treatment agent container 3 with the inner surface of the cover 2, a pair of upper and lower compression coil springs 41, 41, and a spring. The pressing plate 40 is urged by the springs 41 and 41 and the actuators 42 and 42 disposed between the outer surface of the main body 1 and the pressing plate 40, and the pressing plate 40 is the inner surface of the cover 2. For this reason, when the processing agent container 3 is disposed between the cover 2 and the pressing plate 40, the processing agent container 3 is always pressurized.
[0015]
6 and 12, the actuator 42 includes a spring 420 and links 421 and 422, and a connecting shaft 423 that connects the links 421 and 422 is formed by a pair of left and right actuators 42 and 42. The connecting shaft 423 protrudes toward the holding plate 40 by the biasing of one end of the link 421 by the spring 420.
[0016]
As shown in FIGS. 7 to 9, the discharge unit 5 includes a base 57, a head unit 50 including a rib 501 that slide-engages with an arc-shaped groove 572 on the side surface of the base 57, and the base 57 and the head unit 50. Springs 55, 55 that are disposed between the springs 55, 55 for urging the head unit 50 upward, a movable body 52 that is disposed in the head unit 50 so as to be movable up and down, and a lower part of the head unit 50. a receiving member 54 are a tube 56 having a connecting at which flexibility between the connection port 540 and the base 57 of the receiving member 54, respectively distribution to a plurality of discharge ports 500 provided on the upper end surface of the head portion 50 The upper opening diameter d1 of the discharge port 500 is smaller than the diameter D of the ball 51, and the lower opening diameter d2 of the discharge port 500 is larger than the diameter D of the ball 51. Between By the movable member 52 is urged upward by a spring 53 which is, each ball 51 of the is received rotatably.
[0017]
Further, the shaft portion 520 that protrudes below the movable body 52 penetrates the receiving member 54 and protrudes below the connection port 540, and functions as a check valve 521 at the lower end portion of the shaft portion 520. An O-ring is attached. In the figure, reference numeral 541 denotes an O-ring for sealing between the outer periphery of the receiving member 54 and the inner periphery of the head portion 50, and 560 is formed of a flexible rubber body and is disposed in the tube 56. A tube core 561 having a smaller flow passage cross-sectional area is arranged in the base 57, and the flow rate of the processing agent is reduced by reducing the cross-sectional area of the internal flow passage from the lower connection port 570 in the base 57 to the tube 56. A hollow pipe 571 to be fixed is an O-ring which is attached to the outer periphery of the connection port 570 to which the connection port 30 of the treatment agent container 3 is detachably connected and seals with the connection port 30.
[0018]
In the discharge unit 5, the head unit 50 is urged upward by a spring 55 with respect to the base 57, and the movable body 52 and the ball 51 are urged upward with respect to the head unit 50 . In the state, the check valve 521 is closed and the ball 51 closes the discharge port 500. If the upper end of the head unit 50 is pressed against the skin, the ball 51 and the movable body 52 are spring-loaded as shown in FIG. The processing agent in the processing agent container 3 pressurized by the pressurizing means 4 is connected to the connection port 30, sinking against 53 and opening the discharge port 500 and opening the check valve 521. It is discharged to the outside from the discharge port 500 through the space between the outer surface through the the tube 56 base 57, the grooves of which open check valve 521 and the head portion 50 the inner surface and the movable member 51 is formed from . If the upper end of the head unit 50 is further pressed against the skin, a float operation in which the head unit 50 sinks against the spring 55 is performed.
[0019]
Since it is constantly pressurized processing container 3 by the pressurizing means 4, although the treatment agent is always extruded and toward the head portion 50 of the discharge portion 5, not pressing the upper surface of the head portion 50 to the skin In this case, the treatment agent is not discharged. Moreover, even if it uses it not only upward but downward or sideways, the discharge amount of a processing agent does not change, and it can apply | coat a processing agent to skin uniformly. The adjustment screw 29 shown in FIGS. 2, 3 and 8 is for adjusting the discharge amount of the processing agent, and its tip protrudes into the internal flow path of the base 57 of the discharge portion 5.
[0020]
FIG. 12 shows a state when the processing agent in the processing agent container 3 is reduced, and FIGS. 13 to 15 show states when all the processing agent is discharged. When the processing agent is exhausted in this way, as shown in FIG. 14, the pressing plate 40 pushes the detection switch 49 attached to the main body 1 to switch the contact point, so that the control drive circuit in the main body 1 is mounted on the substrate 13. Since the light-emitting diode 130 mounted on the LED is turned on and this lighting can be visually recognized through the light transmitting portion of the cover 2, the user can know that it is time to replace the treatment agent container 3.
As shown in FIG. 11, the pressing plate 40 is larger than the width of the processing agent container 3, and positioning locking portions 105 and 106 for positioning with respect to the main body 1 are also located outside the processing agent container 3. . This is because the remaining amount of the processing agent in the processing agent container 3 can be reduced. For the same reason, the surface of the pressure plate 40 that contacts the treatment agent container 3 has the same shape as the inner surface of the cover 2. Further, the portion between the upper end of the pressing plate 40 and the connection port 30 made of a rigid body of the treatment agent container 3 connected to the connection port 570 of the discharge unit 5 is a portion that cannot be squeezed by the pressing plate 40, With respect to this portion, as shown in FIG. 13, the rib 17 as the protruding portion is protruded from the main body 1 and the cover 2 so as to narrow the space between the main body and the cover. 3 is to reduce the cross-sectional area of said portion.
[0021]
Furthermore, with respect to the pair of upper and lower springs 41 and 41 that pressurize the treatment agent container 3, the lower spring 41 may be strengthened. This is because the processing agent can be pushed out from the lower end side of the processing agent container 3.
[0022]
The treatment agent container 3 is replaced by removing the cover 2 by pushing the detachable button 20 on the cover 2 against the spring bias to release the engagement with the main body 1, and removing the old treatment agent container 3, and then replacing the treatment agent container 3 with a new one. This is performed by connecting the connection port 30 of the treatment agent container 3 to the connection port 570 of the discharge unit 5 and mounting the cover 2 again. Since the total volume of the flow path from the treatment agent container 3 to the discharge port 500 and the cross-sectional area of the flow path are made small, the amount of wasteful treatment agent staying in the discharge portion 5 is small. Even when the agent container 3 is loaded and used, the treatment agent is immediately discharged.
[0023]
The pressurizing means 4 may be provided on the cover 2 side. That is, as shown in FIGS. 16 and 17, the spring 41 and the pressing plate 40 are attached to the inner surface of the cover 2 so as to press the treatment agent container 3 toward the outer surface of the main body 1. Even in this case, if the cover 2 is removed (opened), the pressurizing means 4 is separated from the treatment agent container 3 at the same time as the cover 2, so that the new treatment agent container 3 is attached so as to follow the outer surface of the main body 1. The replacement of the treatment agent container 3 is easy. However, the pressurizing means 4 is preferably on the main body 1 side. Even when the removed cover 2 is dropped, the pressurizing means 4 is not damaged, and vibration during driving of the motor 11 is transmitted to the pressurizing means 4, and the vibration is caused by the frictional resistance of the pressurizing means 4. This is because the processing agent is discharged smoothly.
[0024]
FIG. 18 shows a structure in which the pressing means 4 is provided on the outer surface of the main body 1 and the switch handle 46 is attached to the cover 2. As the switch handle 46 is slid, the contact driving unit 47 arranged along the inner surface of the cover 2 turns the contact on and off.
[0025]
FIG. 19 shows another example of the treatment agent container 3. The treatment agent container 3 here is formed of a non-flexible material having a structure in which a part is crushed by the pressurizing means 4. The pressing plate 40 may constitute the outer shell of the container 3.
[0026]
20 and 21 show the cap 8 for protecting the hair processing section 6 of the main body 1 that also protects the upper end of the head section 50 of the ejection section 5. The cap 8 is shaped so as not to interfere with the cover 2 when the cover 2 is attached / detached, so that the upper end of the body hair treatment unit 6 and the head unit 50 are protected while the cap 8 is attached. Exchanges can be made.
[0027]
In the above example, the main body 1 is provided with the shaving body hair treatment unit 6. However, as shown in FIG. 22, the hair removal claw 71 that is driven to open and close by the hair removal block 70 that is rotationally driven by the motor 75 is provided. The provided hair removal treatment unit 7 for hair removal may be provided.
[0028]
