  On the other hand, as shown in FIG. 1 and FIG. 8, the head portion main body 60 of the treatment head portion 12 attached to the lower end portion of the apparatus main body portion 11 is a cover portion 61 attached to close the lower end opening of the main body housing 13. And a head base portion 62 attached to the cover portion 61.

  The treatment element 70 is provided on the lower surface of the cover 61 so as to be movable relative to the head base 62 (the main body 100).

  In the present embodiment, the treatment element 70 includes four (plural) treatment elements 70A to 70D provided at four places (a plurality of places) in the lower surface portion of the cover portion 61. In addition, in this Embodiment, what made each treatment child 70A-70D the same shape is illustrated.

  Specifically, each of the treatment elements 70A to 70D (the treatment element 70) has a connecting portion 80 connected to a final output shaft (driving shaft) 56 described later, and a lower side of the connecting portion 80 (opposite to the driving shaft) And a treatment projection 95 disposed on the placement surface 91 a of the placement unit 91.

  The connecting portion 80 also includes a substantially cylindrical treatment element base 81 and a bottomed cylindrical treatment element base portion 82 to which the treatment element base 81 is attached.

  Further, in the present embodiment, the four (plural) treatment elements 70A to 70D are provided on the lower surface of the cover 61 so as to eccentrically rotate in different phases. As described above, by eccentrically rotating the plurality of treatment elements 70A to 70D in different phases around the central axis, the treatment elements 70A to 70D are carried to the downstream side in the movement direction X while sandwiching the scalp. It is made to be driven.

  In the scalp care device 10 having such a treatment element 70, for example, when the user applies the scalp care device 10 to his / her side, the movement direction X is the lift-up direction (direction toward the top of the head) Holding in such a way as to become a preferred use example.

  Therefore, in the present embodiment, when gripping the scalp care device 10, with the palm facing the gripping surface 15, the three fingers or four fingers other than the thumb of the hand are the arch portion 14 and the gripping surface 15 It is assumed to be inserted along the finger insertion direction ID (see the arrow in FIG. 1 etc.) in the finger insertion hole 16 between the two.

  When the scalp care device 10 is gripped by the assumed gripping method, the longitudinal direction of the three or four fingers of the gripping hand becomes parallel to the movement direction X. Furthermore, the direction of the fingertips of three or four fingers holding the hand coincides with the movement direction X of the scalp care device 10.

  Therefore, when the user places the plurality of treatment elements 70A to 70D on the right side and the left side of the head with the finger tips holding the scalp care device 10 facing upward and performs scalp massage, The operating direction X of the treatment elements 70A to 70D is the lift-up direction.

  On the other hand, when the user wants to massage the back of the head in a lift-up direction, etc., if the user takes a massage posture in which the hand is turned over to the back of the head (or over the shoulder) Direction X) is downward. In such a case, it is preferable to hold the scalp care device 10 by inserting three or four fingers from the opposite side of the finger insertion direction ID so that the movement direction X is the lift-up direction.

  As described above, in any case, in order to perform scalp massage so that the movement direction X is the lift-up direction, it is necessary to recognize which direction the movement direction X is. In the embodiment, by making the extending direction of the arch portion 14 orthogonal to the operating direction X, it is easily recognized that the direction perpendicular to the extending direction from the extending direction of the arch portion 14 is the operating direction X. I am able to do it.

  Furthermore, in order to allow the motion direction X of the scalp care device 10 to be recognized up to that direction, it is necessary for the user to recognize that the arrow direction shown in FIG. 1 is the finger insertion direction ID. In this embodiment, in order to make the user recognize that the direction indicated by the arrow in FIG. 1 is the finger insertion direction ID, in addition to the device in the extending direction of the arch portion 14, the inner circumferential surface of the arch portion 14 and The shape of the gripping surface 15 is devised.

  Here, each surface which comprises the outer peripheral surface of the main body housing 13 is defined as follows.

  First, the surface on the extension base end side where the arch portion 14 extends (arch installation surface) is defined as the side surfaces 13b and 13b, respectively. And the surface located on the downstream side of the operation direction X of the treatment head 12 is the surface facing the front 13 c of the apparatus body 11 and the surface 13 c facing the front 13 c of the device body 11 and located upstream of the operation direction X of the treatment head 12 The face is defined as the back face 13d.

  Hereinafter, the device of said shape is demonstrated.

  The upper surface of the device body 11, that is, the gripping surface 15 (upper surface of the main body) on which the user places the abdomen and palm of the finger when gripping is convex in the side view shown in FIGS. 2 (c) and 2 (d). It is formed to be an arc-shaped surface.

  That is, the front upper end portion 13e on the front surface 13c side of the upper surface 11b (gripping surface 15) of the device body 11 and the rear upper end portion 13f on the rear surface 13d side of the upper surface 11b are the operating direction X on the upper surface 11b (finger insertion direction ID It is arranged at a lower position than the upper surface central portion 15a which is the central portion of.

  As described above, in the present embodiment, the gripping surface 15 is formed to be a convex arc-shaped surface that can be easily gripped by the palm when the palm or the like is placed on the gripping surface 15 and gripped. Is easy to grip the scalp care device 10.

  The grip surface 15 which is an example of the housing outer surface formed in a convex arc shape is a surface of a portion located on the finger insertion direction ID side (the entrance side of the finger insertion direction ID) with respect to the upper surface center portion 15a in the finger insertion direction ID. The curvature of the surface of the portion located on the opposite side (outlet side) of the finger insertion direction ID is larger than the curvature of.

  By doing this, when a finger is inserted from an inappropriate direction opposite to the finger insertion direction ID, the palm placed on the gripping surface 15 can be made to feel uncomfortable due to the difference in the curvature of the gripping surface 15 There is.

  As a result, the user recognizes that the insertion direction is inappropriate from the sense of incongruity of the palm placed on the gripping surface 15, and the user can reinsert the finger from the appropriate finger insertion direction ID. It is possible for a person to hold the scalp care device 10 by an appropriate holding method.

  Furthermore, as shown in FIGS. 2 (c), 2 (d) and 3 on the gripping surface 15, which is an example of the main body outer surface facing the arch portion 14, the operating direction X side of the treatment elements 70A to 70D. When viewed from above, a convex portion 15 c that bulges into a convex curved surface is formed. The convex portion 15 c is formed at the central portion of the surface of the portion of the grip surface 15 located on the entrance side of the finger insertion direction ID.

  Then, when the user places the palm along the convex arc shape of the gripping surface 15 and holds the scalp care device 10 with a finger, the convex portion 15 c is placed on the central portion of the palm placed on the gripping surface 15. It is formed in the position corresponding to the hollow that can be formed to be a convex shape corresponding to the concave shape of the hollow of the palm.

  By this, when the user holds the scalp care device 10 in an appropriate state, the holding surface 15 can be naturally surrounded by the palm. Therefore, when the insertion direction of the user's finger is inappropriate, it can be recognized from the sense of incongruity of the palm when holding the upper part of the device body 11 that the insertion direction is improper.

  With this configuration, the user can more easily recognize the movement direction X of the treatment elements 70A to 70D, and can hold the scalp care device 10 by an appropriate holding method.

  Further, as shown in FIGS. 2 (a), 2 (b) and 3, the grip surface 15 (upper surface of the main body) is a concave in which the central portion 15b in the width direction is concave when viewed from the front surface 13c and the back surface 13d. It is formed to have an arc shape.

  By doing this, the central portion in the width direction of the finger insertion hole 16 formed between the arch portion 14 and the gripping surface 15 is made relatively wide in the vertical direction.

  Here, the central portion 15 b forms a concave arc shape in the widthwise central portion of the gripping surface 15, and the concave arc shaped surface portion extends from the upper central portion 15 a of the gripping surface 15 both forward and backward. It extends. In the central portion 15b, the center line of the grip surface 15 extending from the upper surface central portion 15a to the front upper end portion 13e (the width center line of the concave arc-shaped central portion 15b) is convex.

  By doing this, when the user grips the scalp care device 10 in an appropriate state, the gripping surface 15 can be naturally surrounded by the finger, and the operation of the treatment elements 70A to 70D can be more easily performed. It becomes possible to recognize the direction X.

  Further, as shown in FIGS. 2A and 2B, in the width direction orthogonal to the operation direction X, the side end 13g serving as the root of the arch portion 14 is closer to the upper surface center 15a of the gripping surface 15. Is also placed in high position. By doing this, the gripping surface 15 is made to have a surface shape matching the palm shape.

  Similarly to the cover 61, the treatment element base 82 can also be made of a flexible member such as an elastomer. In the present embodiment, the treatment element base portion 82 and the cover portion 61 are integrally formed.

  And as shown in FIG. 6, the following deformation part 61d of the cover part 61 is provided in the circumference | surroundings of the treatment element base part 82 which comprises treatment element 70A-70D. The following deformation portion 61d has a concave shape that opens on the treatment projection 95 side of the treatment elements 70A to 70D, and is configured to be elastically deformed in the direction orthogonal to the vertical direction (axial direction). By doing this, when the treatment element base 81 moves in the direction perpendicular to the vertical direction (drive shaft direction) by the treatment element base 81, the following deformation portion 61d follows the operation of the treatment element base 82. I am trying to deform. The following deformation portion 61d may be in the form of a bellows.

  Further, the treatment element base portion 82 is provided with fitting convex portions 82a (see FIG. 14) fitted to the plurality of concave portions 81c formed on the distal end side of the treatment element base 81.

  In the present embodiment, the concave portion 81 c is filled with the resin member constituting the cover portion 61 and the treatment element base portion 82 in a state in which the treatment element base 81 is disposed in the mold. What shape | molded the fitting convex part 82a so that it may become a shape corresponding to 81c is illustrated. That is, the two-part molding illustrates the treatment element base 81, the treatment element base portion 82 and the cover portion 61 as an integral part joined by the resin material filled in the concave portion 81c.

  As described above, in the present embodiment, the connecting portion 80 in which the treatment element base 81 and the treatment element base portion 82 are integrally formed is connected to the final output shaft (drive shaft) 56.

  And the arrangement | positioning part 91 which has the arrangement | positioning surface 91a in which the treatment processus | protrusion 95 is arrange | positioned is detachably attached to the downward direction (an opposite side to a drive shaft) of this connection part 80. FIG.

  A plurality of treatment projections 95 extend downward from the arrangement surface 91 a of the arrangement portion 91, and three small diameter projections 95 a are formed at the tip of each treatment projection 95.

  Further, in the present embodiment, the treatment projection structure 90 is formed by integrating the placement portion 91 and the treatment projection 95, and the treatment projection structure 90 can be detachably attached to the connection portion 80. There is. Specifically, the treatment projection structure 90 is formed by press-fixing the fitting projection 94 formed to extend upward to the treatment projection structure 90 in the fitting recess 82 b of the treatment element base portion 82. Are attached to the connecting portion 80.

  By doing this, the treatment projection structure 90 is easily attached by the connecting portion 80.

  Furthermore, in the present embodiment, the treatment projection structure 90 is formed by two-color molding of different materials having different rigidity.

  Specifically, as shown in FIG. 16, FIG. 17, FIG. 19 and FIG. 20, the surgical projection structure 90 is a core material 71 having a rigidity (relatively high rigidity) formed using a resin material or the like. And a cover 72 which is formed to have elasticity using an elastomer material or the like and covers the core material 71. Thus, in the present embodiment, the rigidity of the cover 72 is lower than that of the core material 71.

  The core 71 is a placement side core 71 a that becomes a part of the placement part 91 when the treatment projection structure 90 is formed, and a treatment that becomes a part of the treatment projection 95 when the treatment projection structure 90 is formed. A projection side core member 71b is provided, and the treatment projection side core member 71b and the arrangement portion side core member 71a are integrally formed.

  The cover 72 is an arrangement portion side cover 72a which is a part of the placement portion 91 when the treatment projection structure 90 is formed, and a treatment projection side which is a part of the treatment projection 95 when the treatment projection structure 90 is formed. A cover 72b is provided, and the treatment projection side cover 72b and the placement portion side cover 72a are integrally formed.

  Then, by forming the cover 72 in two colors so as to cover the surface of the core material 71, a treatment projection structure 90 in which the core material 71 and the cover 72 are integrated is formed. Therefore, in the present embodiment, the placement portion 92 and the treatment projection 95 are integrally formed.

  The fitting protrusion 94 described above is formed on the placement-portion-side core 71 a of the core 71, and the cover 72 is not formed on the fitting protrusion 94.

  As described above, the treatment projection structure 90 is formed by two-color molding using different materials having different rigidity, and the treatment projection 95 is optimized based on the followability to the curved surface shape of the scalp while the rigidity of the placement portion 91 is optimized. It is possible to make settings such as optimizing the stiffness of the treatment based on the comfort of the operation sense. That is, each stiffness can be optimized from another point of view.

  Although in the present embodiment, the treatment protrusion 95 is also formed with the core member 71 (the treatment projection side core member 71b), the core member 71 is formed only in the placement portion 91. And the entire treatment projection 95 may be formed only by the cover 72.

  The cover 72 may be removable from the core 71 so that the cover 72 can be removed for cleaning or replacement. In this case, it is also possible to fix the core 71 in a state where it can not be removed to the connecting portion 80, and only the cover 72 can be detachably attached.

  In addition, it is also possible to fix the entire treatment element 70 in a state where it can not be removed from the main body portion 100 or the head base portion 62.

  Here, in the present embodiment, the number of the treatment projections 95 disposed on the placement surface 91a is increased to further enhance the treatment effect of the scalp.

  However, if the number of treatment projections 95 is increased without changing the area of the arrangement surface 91a, the arrangement density of the projections becomes high, and there is a possibility that hair etc. may be entangled at the time of use, so the arrangement density increases. It is preferable to be able to increase the number of treatment projections 95 while suppressing the

  In addition, if the connecting portion 80 itself is enlarged, it is possible to increase the number of the treatment projections 95 while suppressing an increase in the arrangement density, but in such a configuration, the apparatus becomes larger. It will

  Therefore, in the present embodiment, only the placement portion 91 in the portion excluding the treatment projection 95 of the treatment element 70 from the lower end portion (position portion side end portion) 80a of the connection portion 80 in a direction intersecting the drive shaft. By extending it, the area of the arrangement surface 91 a is increased to increase the number of treatment projections 95. By doing so, the number of the treatment projections 95 can be increased while suppressing the increase in size of the device and suppressing the decrease in the distance between the treatment projections.

  As described above, in the present embodiment, the placement portion main body 92 covering the lower end portion (the placement portion side end portion) 80 a of the connection portion 80 when the placement portion 91 is viewed from the vertical direction (drive shaft direction); And an extending portion 93 protruding outward from the lower end portion (arrangement portion side end portion) 80a.

  The placement portion main body 92 is formed to have the same diameter as the outer peripheral diameter of the lower end surface 80b of the connection portion 80, and the entire lower end surface 80b is disposed when viewed from the vertical direction (drive shaft direction). It is made to be covered by the main part body 92.

  On the other hand, the extending portion 93 is formed so as to protrude radially outward from the outer peripheral edge portion of the placement portion main body 92.

  The arrangement surface 91 a is formed by the arrangement portion main body side surface 92 a of the arrangement portion main body 92 and the extension portion side surface 93 a of the extension portion 93.

  By doing this, the area of the arrangement surface 91a in a state viewed from the vertical direction (drive shaft direction) can be increased, and the treatment projection is compared to the case where the treatment projection 95 is disposed in the lower end surface 80b of the connecting portion 80. The number of 95 can be increased. In the present embodiment, eight treatment projections 95 having the same shape are arranged on the arrangement surface 91a.

  Furthermore, in the present embodiment, the extension portion 93 protrudes in the direction opposite to the center CP of the main body portion 100 when viewed from the vertical direction (drive shaft direction).

  Specifically, when viewed from the vertical direction (drive shaft direction), the center of the placement portion main body 92 (final output shaft 56: the centers P1 to P4 of the treatment element base portion 82 to be described later) passes through; The extended portion 93 is formed only in an area outside the straight line orthogonal to the straight line connecting the center of the main body 100 and the center CP of the main body 100 (a semicircular portion on the outer side in the diagonal direction of the main body 100).

  As described above, in the present embodiment, in the arrangement portion 91, the distance R2 from the final output shaft (drive shaft) 56 to the outer end 91c is larger than the distance R1 to the inner end 91b.

  That is, the placement section 91 is configured such that the longest distance from the final output shaft (drive shaft) 56 to the end is larger on the outer peripheral side of the main body than on the CP side of the main body.

  Furthermore, in the present embodiment, the outer peripheral edge of the extending portion 93 is formed so as to draw a circular arc.

  Further, in the present embodiment, the placement portion 91 is inclined so that the outer side of the center CP side of the main body portion 100 is separated from the main body portion 100.

  At this time, in a state where the distal end of the treatment projection 95 is directed upward, the arrangement surface 91 a is inclined so that the center CP side of the main body 100 is downward.

  Furthermore, in the present embodiment, as shown in FIGS. 19 and 20, the extending portion side surface 93a is more inclined than the placement portion main body side surface 92a (the lower end surface 80b in the state of being attached to the connecting portion 80). And the angle between the

  In this way, the tip of each treatment projection 95 can be inclined without changing the length of each treatment projection 95, and the virtual surface formed by the tip of each treatment projection 95 can be made close to the shape of the scalp curved surface. Will be able to

  By the way, if the arrangement surface 91a is enlarged and the number of treatment projections 95 is increased, the contact point between the tip of the treatment projections 95 and the curved surface of the scalp is increased, resulting in geometrically excessive restraint and the tip position of the treatment projections 95 It may be difficult to fit on the scalp surface.

  Therefore, in the present embodiment, the inclination of the arrangement surface 91a is slightly larger than that of the real head, and the arrangement surface 91a is made to have elasticity in the vertical direction (the drive axis direction).

  As described above, by providing elasticity in the vertical direction (drive shaft direction) to the disposition surface 91a having a slope slightly larger than the real head, the followability of the tip position of the treatment projection 95 to the head shape is improved. Can. As a result, the tip position of the treatment projection 95 can be easily fitted to the curved surface of the scalp.

  Further, in the present embodiment, the outer peripheral end of the extending portion 93 is positioned above the head portion main body 60 with the distal end of the treatment projection 95 directed upward.

  With this configuration, when the treatment elements 70A to 70D are rotated, interference between the extension portions 93 can be suppressed. Furthermore, interference of the extension portion 93 with the head portion body 60 can be suppressed. As a result, the area of the arrangement surface 91a can be greatly expanded.

  In addition, if it is possible to prevent the extension portion 93 from interfering with the head portion main body 60, the extension portion 93 is provided outside the head portion main body 60 when the treatment elements 70A to 70D are rotated. The treatment range can be expanded without increasing the size of the apparatus (main body 100) (see FIG. 21A).

  In addition, although the thing using the treatment projection structure 90 which integrated the arrangement | positioning part 91 and the treatment process projection 95 was illustrated in this Embodiment, forming the arrangement | positioning part 91 and the treatment projection 95 with another components Is also possible.

  At this time, the treatment projection 95 may be detachably attached to the placement portion 91, or the treatment projection 95 may be fixed to the placement portion 91 in a state where it can not be removed. In addition, the placement portion 91 can be detachably attached to the connection portion 80, or the placement portion 91 can be fixed to the connection portion 80 in a state where it can not be removed.

  When the treatment projection 95 is detachably attached to the placement portion 91, a plurality of kinds of treatment projections may be prepared and appropriately changed according to the preference of the user.

  Moreover, it is also possible to integrally form the placement portion 91 and the treatment projection 95 using the same material. At this time, it is preferable that the placement portion 91 and the treatment projection 95 be formed of a flexible member such as an elastomer as in the case of the cover portion 61, and the placement surface 91a have elasticity in the drive axis direction.

  The one-piece molded article (the treatment projection structure) can also be detachably attached to the connecting portion 80, or can be fixed to the connecting portion 80 in a non-removable state.

  Next, the operation of the scalp care device 10 configured as described above will be described.

  The extending direction of the arch portion 14 provided in the scalp care device 10 is orthogonal to the operation direction X of the scalp care device 10, and the user moves from the extending direction of the arch portion 14 to the operating direction X Can be recognized.

  Then, for example, in the case of normal use such as scalp care of the temporal region, three fingers or four fingers are inserted into the finger insertion holes 16 from the finger insertion direction ID, and the upper surface portion of the device body 11 is gripped. According to the gripping method during normal use, the thumb is located on the operation panel portion 20 side, so it is possible to operate the switch operating member 22 using the thumb of the gripped hand.

  Then, when the switch operation member 22 is pressed, the power is switched from the off state to the on state, and the motor 32 is driven to rotate the treatment elements 70A to 70D.

  When the treatment projections 95 (small-diameter projections 95a) of the rotating treatment members 70A to 70D are brought into contact with the scalp, the user's scalp is moved according to the movement of the treatment projections 95, and the scalp is care (massage) Be done. At this time, each of the treatment elements 70A to 70D operates so as to move the scalp in one direction based on the operation of the gears 42 and 46A to 46D and the arrangement relationship of the rotary base 55.

  Next, rotation operation of each of the treatment elements 70A to 70D provided in the scalp care device 10 will be described mainly with reference to FIG. In FIG. 21, the direction orthogonal to the paper surface corresponds to the vertical direction, and the horizontal direction in FIG. 21 is described as the horizontal direction of the scalp care device 10, and the vertical direction in FIG.

  The four treatment elements 70A to 70D are connected to the connecting shaft 47 arranged in a substantially square shape in plan view through the rotary base 55, the final output shaft (drive shaft) 56 and the treatment element base 81, respectively. They are arranged at positions forming four vertices of a substantially square in a bottom view (bottom view).

  Among them, the treatment elements 70A and 70B adjacent to each other in the front-rear direction rotate counterclockwise with the centers P1 and P2 of their treatment element base portions 82 about 180 degrees out of phase with each other about the connecting shafts 47.

  On the other hand, the treatment elements 70C and 70D adjacent to each other in the front-rear direction rotate clockwise with the centers P3 and P4 of their treatment element base portions 82 about 180 degrees out of phase with each other about the connecting shafts 47.

  In the state where the treatment elements 70A to 70D are respectively connected to the final output shaft (drive shaft) 56, the centers P1 to P4 of the treatment element base portion 82 are the final output shafts to which the treatment elements 70A to 70D are connected ( The drive shaft substantially coincides with the drive shaft 56.

  Further, in the treatment elements 70A and 70C (the treatment elements 70B and 70D) adjacent to each other in the left-right direction, the centers P1 and P3 (P2 and P4) of the treatment element base portions 82 thereof are perpendicular to the vertical bisector L. Rotate to be line symmetrical.
