  The outer peripheral surface of the overhanging portion 126 is formed as an outer convex curved surface.

  A plurality of convex portions 137 or concave portions are formed along the outer peripheral surface of the overhang portion 126.

  A heat source 111 having a cylindrical heat supply surface 134 is disposed along the rotation axis P of the roller 109.

  The beauty instrument according to the present invention includes a skin contact body 2 including rolling elements 29 and 109 capable of rolling on the skin surface, and a heat source 3 and 111 for heating or cooling at least a part of the skin contact body 2. According to this, the skin contact body 2 heated or cooled by the heat source 3 or 111 is pressed against the skin surface in parallel with rolling the rolling elements 29 and 109 on the skin surface to apply pressure stimulation. In addition, thermal stimulation (thermal stimulation or cold stimulation) can be applied to the skin surface. As described above, according to the beauty appliance according to the present invention, various stimuli can be applied as compared with the conventional beauty appliance that applies only the pressure stimulus to the skin surface, and therefore, the beauty treatment can be effectively performed. it can.

  When the ball 29 as a rolling element is supported by the heat receiving body 28, the heat from the heat source 3 can be conducted to the ball 29 through the heat receiving body 28 to heat or cool the ball 29. By rolling the ball 29 on the skin surface, pressure stimulation and thermal stimulation can be simultaneously applied by the ball 29. By making the pressure stimulus and the heat stimulus imparting body the same, it is possible to simultaneously apply two stimuli to one place on the skin surface at a pinpoint. Further, when the ball 29 is free to rotate in all directions, the heat transmitted from the heat receiving body 28 to the ball 29 can be transmitted to the skin surface without unevenness. When the ball 29 is rotated only around one rotation axis, it is difficult to transmit the heat of the portion to the skin surface by touching the pole of the ball 29 or the vicinity thereof to the skin surface.

  When a skin stimulation surface 42 is provided on the outer surface of the heat receiving body 28 and the skin is stimulated by the ball 29 and the skin stimulation surface 42, pressure stimulation by rolling the ball 29 on the skin surface, and the skin surface to the skin. Pressure stimulation by rubbing on the stimulation surface 42 can be applied, and pressure stimulation applied to the skin surface can be diversified.

  A ball holding recess 38 for freely supporting the ball 29 is provided in the inner recess 35 formed in the heat receiving body 28, and the recess 38 contacts the surface of the ball 29 in a point contact or line contact manner. As a result, the sliding resistance when the ball 29 rolls can be reduced, and the ball 29 can be smoothly rolled on the skin surface.

  When the depth dimension T1 of the ball holding recess 38 is set to be less than half of the diameter R of the ball 29, the space between the wall surface of the ball holding recess 38 and the surface of the ball 29 is reduced, and the air layer interposed therebetween is thinned. Therefore, the efficiency of heat conduction from the wall surface of the ball holding recess 38 to the ball 29 can be improved.

  If the distance T3 in the front-rear direction from the heat receiving surface 32 to the inner back surface of the housing recess 35 is set to be smaller than the diameter R of the ball 29, the heat transfer wall 31 sandwiched between the heat receiving surface 32 and the inner back surface of the housing recess 35. The heat receiving body 28 can be reduced in weight, and the heat of the heat source 3 can be quickly transmitted to the inner back surface of the housing recess 35.

  When the depth dimension T1 of the ball holding recess 38 is set smaller than the distance T2 from the heat receiving surface 32 to the inner back surface of the ball holding recess 38, the distance between the wall surface of the ball holding recess 38 and the surface of the ball 29 is reduced. Since the air layer interposed therebetween can be thinned, the efficiency of heat conduction from the wall surface of the ball holding recess 38 to the ball 29 can be improved.

  If the inner back corner of the housing recess 35 is formed in a partial spherical shape, the distance between the inner back corner of the housing recess 35 and the surface of the ball 29 can be reduced, and the air layer interposed therebetween can be made thinner. Further, the efficiency of heat conduction from the inner back corner of the housing recess 35 to the ball 29 can be improved.

  When the inner back corner of the ball holding recess 38 is formed in a partial spherical shape, the distance between the inner back corner of the ball holding recess 38 and the surface of the ball 29 can be reduced, and the air layer interposed therebetween can be made thinner. Therefore, the efficiency of heat conduction from the inner and inner corners of the ball holding recess 38 to the ball 29 can be improved.

  When the accommodation recess 35 having the narrow ball window 64 and the insertion port 65 is formed in the heat receiving body 28 and the ball 29 is enclosed in the accommodation recess 35 by the lids 62 and 63 that close the insertion port 65, the ball 29 is moved to the ball window 64 or It can be reliably prevented from coming out of the insertion port 65. Further, the ball 29 can be supported with high accuracy while simplifying the structure of the heat receiving body 28.

  When the heat source 3 and the electrical component unit 4 are incorporated in the main body case 1, the skin contact body 2 can be separated from the heat source 3 and the electrical component unit 4 when the skin contact body 2 is removed from the main body case 1. The washing operation of the skin contact body 2 can be facilitated.

  When the heat receiving surface 32 of the skin contact body 2 and the heat supply surface 49 of the heat source 3 are intimately biased by the elastic bodies 6 and 75, the heat conduction efficiency from the heat source 3 to the skin contact body 2 can be improved.

  When the elastic body 6 that closely urges the heat source 3 toward the skin contact body 2 is incorporated in the main body case 1, the structure of the skin contact body 2 is simplified and the skin contact body 2 in a state separated from the main body case 1 is handled. Can be facilitated.

  When the elastic body 75 that closely urges the heat receiving body 28 toward the heat source 3 is provided on the skin contact body 2 side, the assembly structure of the heat source 3 to the body case 1 is simplified, and the cost is reduced accordingly. Can do. In particular, fixing the heat source 3 to the main body case 1 can well prevent the heat source 3 from being damaged and poor conduction with the electrical component unit 4.

  If the heat transfer convex part 70 and the heat transfer recessed part 71 which mutually engage are provided in the contact surface of the heat source 3 and the skin contact body 2, compared with the case where the said contact surface is made into a flat surface, the heat source 3 and the skin contact body 2 Therefore, the heat conduction efficiency from the heat source 3 to the skin contact body 2 can be improved.

  When the heat source 3 is fixed to the heat receiving body 28 of the skin contact body 2, the heat receiving body 28 and the heat source 3 are securely brought into close contact with each other, and the heat transfer from the heat source 3 to the heat receiving body 28 can be performed satisfactorily.

  When the skin contact body 2 also serving as a skin electrode and the grip electrode 58 provided in the main body case 1 supply current to the skin surface via the human body, current stimulation can be applied to the skin surface in addition to pressure stimulation and thermal stimulation. It is possible to perform more diverse and effective cosmetic treatment on the skin surface. In the present invention, the current stimulation is not limited to the stimulation by the weak current, but includes the ion introduction processing and the ion derivation processing. Furthermore, the muscle current is set at a higher voltage than that during the ion introduction processing or the ion derivation processing. It is a concept that includes stimuli.

  If the ball 29 is also used as a skin electrode, the skin contact body 2 can be simplified compared with the case where a skin electrode is provided separately from the ball 29, and the cost can be reduced accordingly.

  Since the spring 104 that moves and urges the ball 29 toward the ball window 102 is stably adhered to the ball 29 by its own elasticity, the ball 29 and the lead wire 106 are electrically connected via the spring 104. Thus, it is possible to reliably prevent the energization failure between the ball 29 and the lead wire 106.

  When one end of the spring 104 is received by the heat transfer plate 47 of the heat source 3, the ball 29 can be stably supported by the other end of the spring 104. Further, since heat can be supplied from the heat transfer plate 47 to the ball 29 via the spring 104 to heat or cool the ball 29, the ball 29 and the ball 29 and the heat transfer structure can be separated from the spring 104. The structure around the heat transfer plate 47 can be simplified, and the cost can be reduced accordingly.

  If the plurality of balls 29 are arranged inside the outline of the skin stimulation surfaces 42 and 43, the plurality of balls 29 and the skin stimulation surfaces 42 and 43 can be simultaneously pressed against the skin surface. Accordingly, it is possible to apply pressure stimulation by simultaneously rolling a plurality of balls 29 on the skin surface, and to apply pressure stimulation and thermal stimulation by rubbing the skin surface with the skin stimulation surfaces 42 and 43. A variety of stimuli can be applied simultaneously.

  If the shape connecting the centers of the balls 29 arranged in the skin stimulation surfaces 42 and 43 is formed into a regular polygonal shape, it is possible to improve the design of the beauty instrument and increase its commercial value. In addition, when a plurality of balls 29 are rolled on the skin surface, it is possible to apply pressure stimulation by pinching the skin surface with two adjacent balls 29 and applying a pressure stimulation provided by the beauty tool. Can be diversified.

  When the shape connecting the centers of the respective balls 29 arranged in the skin stimulation surfaces 42 and 43 is formed in a trapezoidal shape, when the plurality of balls 29 are rolled on the skin surface, It is possible to apply pressure stimulation by pinching the surface and diversify the pressure stimulation applied by the beauty tool. If the balls 29 are arranged in a trapezoidal shape, the distance between two adjacent balls 29 can be diversified. That is, the distance between the two balls 29 arranged at both ends of the upper base of the trapezoid and the two balls 29 arranged at both ends of the lower base are different. The two balls 29 having a relatively small interval can pinch the skin surface relatively strongly, and the two balls 29 having a relatively large interval can pinch the skin surface relatively weakly. That is, a plurality of pressure stimuli with different strengths can be applied to the skin surface.

  Since the pressure stimulation applied to the skin surface by the balls 29 is relatively large, the balls 29 are concentrated by making the sum of the projected areas of the exposed portions of the balls 29 smaller than the areas of the skin stimulation surfaces 42 and 43. It can avoid and the pressure stimulus which the whole skin contact body 2 provides to a skin surface can be made into the moderate thing which is not too strong.

  According to the beauty tool in which the two rollers 109 as the rolling elements are arranged adjacent to each other, pressure stimulation can be applied to a human body part such as a hand or an arm inserted between the two rollers 109. When the projecting end portion 123, the outer convex bulging portion 124, the inner concave constricted portion 125, and the overhanging portion 126 are formed in the order of description from the projecting end side to the base end side of the roller 109, two adjacent rollers 109 are formed. The facing interval of can be varied depending on the location. A human body part can be pinched relatively strongly at a place where the interval is relatively small, and a human body part can be pinched relatively weakly at a part where the interval is relatively large. That is, the pressure stimulus can be increased or decreased.

  When the minimum facing distance W1 of the bulging part 124 of the two rollers 109, the maximum facing distance W2 of the constricted part 125, and the minimum facing distance W3 of the overhanging part 126 are set to a relationship of inequality W3 <W1 <W2. The bulging portion 124 and the overhanging portion 126 can be simultaneously brought into contact with a human body part such as a hand or an arm inserted between the rollers 109 from the protruding end side. Accordingly, it is possible to simultaneously apply pressure stimulation by pinching the human body part with both bulging portions 124 and pressure stimulation by rubbing the human body part with both overhanging portions 126.

  When the outer diameter R2 of the overhanging portion 126 is set smaller than the outer diameter R1 of the head 121, the overhanging portion 126 is prevented from contacting and interfering with the hand gripping the main body case 1 and the like. The usability of the instrument can be improved.

  If the outer peripheral surface of the overhanging portion 126 is formed as an outwardly convex curved surface, the skin contact of the overhanging portion 126 with respect to a human body part such as a hand or an arm can be made smooth, and the fit of the overhanging portion 126 can be improved. .

  When a plurality of convex portions 137 or concave portions are formed along the outer peripheral surface of the overhanging portion 126, the roller 109 rotates along the skin surface, so that the convex portion 137 with respect to the skin surface in contact with the overhanging portion 126. Or a pressure stimulus can be given one after another by a recessed part. Thereby, the pressure stimulation by rubbing a human body part with the overhang | projection part 126 can be improved.

  When the heat receiving body 120 that conducts the heat of the heat source 111 to the roller 109 includes the heat receiving piece 133 that elastically adheres to the heat supply surface 134 of the heat source 111 and rotates together with the roller 109, In this case, the heat of the heat source 111 can be reliably conducted to the heat receiving body 120 to heat or cool the roller 109.

  When the sliding terminal 135 elastically contacting the current supply surface 136 of the internal electrode 117 is fixed to the inner surface of the roller 109, the current supply from the internal electrode 117 to the roller 109 is always ensured even during the rotation of the roller 109. And it can be performed well.

  When each roller 109 is supported so as to be movable along the rotation axis P, the facing distance between the two rollers 109 can be changed depending on the movement position. Therefore, the beauty tool of the present invention can be applied to a plurality of human body parts having different thicknesses such as palms, arms, and thighs. Specifically, both rollers 109 are moved so as to match the thickness of the human body part to be applied, the facing distance is adjusted, the part is sandwiched by both rollers 109, and the beauty tool is reciprocated along the skin surface. By making it move, a pressure stimulus can be given to the said site | part.

  From the protruding end 123 of the roller 109 toward the base end side, when the outer convex bulging portion 124, the inner concave constricted portion 125, and the protruding portion 126 are formed in the order of description, the two adjacent rollers 109 face each other. The interval can vary depending on the location. A human body part can be pinched relatively strongly at a place where the interval is relatively small, and a human body part can be pinched relatively weakly at a part where the interval is relatively large. That is, the pressure stimulus can be increased or decreased. In addition, the user prefers a plurality of human body parts having different thicknesses in combination with the fact that the two rollers 109 can be moved along the rotation axis P to change the facing distance between the two rollers 109. Pressure stimulation can be applied with strength.

  When the outer diameter R2 of the overhanging portion 126 is set to be smaller than the outer diameter R1 of the head 121, the overhanging with respect to the hand holding the main body case 1 or the like, particularly when the roller 109 is moved to the proximal end side. It is possible to eliminate the contact interference of the part 126 and improve the usability of the beauty tool.

  When each roller 109 is composed of a first divided body 147 and a second divided body 148, and the first divided body 147 is supported so as to be movable along the rotation axis P, the facing interval between the first divided bodies 147 can be freely changed. it can. Therefore, the beauty tool of the present invention can be applied to a plurality of human body parts having different thicknesses such as palms, arms, and thighs. Specifically, the first divided body 147 is moved so as to match the thickness of the human body part to be applied, the facing interval is adjusted, and the corresponding part is moved by the bulging portions 124 of both the first divided bodies 147. By sandwiching and reciprocating the beauty tool along the skin surface, pressure stimulation can be applied to the site. At the same time, the overhanging portion 126 of the second divided body 148 away from the first divided body 147 can be brought into contact with the skin surface to apply pressure stimulation. That is, according to the present invention, pressure stimulation can be simultaneously applied to the wide range of the skin surface by the two divided bodies 147 and 148.

  If the first divided body 147 and the second divided body 148 can be rotated independently of each other, when the divided bodies 147 and 148 are reciprocated along the skin surface, the divided bodies 147 and 148 are brought into contact with the skin surface. Therefore, it is possible to eliminate the occurrence of large friction between the divided bodies 147 and 148 and the skin surface, and to smoothly reciprocate the divided bodies 147 and 148 along the skin surface.

  If the roller 109 can be expanded and contracted in the radial direction, the strength of the force that pinches the human body part between the two rollers 109 can be adjusted to the user's preference by adjusting the facing distance between the two rollers 109. .

First Embodiment FIGS. 1 to 5 show a first embodiment of a beauty tool according to the present invention. In the present invention, front / rear, left / right, and upper / lower follow the cross arrows shown in the figure and the front / rear, left / right, and upper / lower indications shown near each arrow. 1 and 2, the beauty tool includes a vertically long main body case 1 that also serves as a grip, a skin contact body 2 that is disposed on the upper front of the main body case 1, and a Peltier unit (heat source) that heats or cools the skin contact body 2. 3 and an electrical component unit 4 for controlling the driving state of the Peltier unit 3 and the like.

  The skin contact body 2 is provided detachably with respect to the main body case 1, and the Peltier unit 3 and the electrical component unit 4 are incorporated in the main body case 1. The Peltier unit 3 is disposed behind the skin contact body 2, and the front surface of the Peltier unit 3 is exposed from the heat transfer window 5 formed in the upper front portion of the main body case 1 so as to face the rear surface of the skin contact body 2. Yes. The Peltier unit 3 is assembled so as to be movable back and forth with respect to the main body case 1. The pair of upper and lower springs (elastic bodies) 6 incorporated in the main body case 1 are in close contact and urged toward the skin contact body 2. It is.

  The electrical component unit 4 is composed of two batteries 9 housed in the lower part of the main body case 1 and a control board 10, and a pair of upper and lower switches 11 and 12 on the front surface of the control board 10 and a beauty tool. A display unit 13 for displaying the operation state is mounted. The upper switch 11 is a power switch for turning on / off the supply of drive current from the battery 9 to the Peltier unit 3 and the like, and the lower switch 12 is a mode switch for switching the operation mode of the beauty tool. Switch. The display unit 13 is composed of four LEDs arranged side by side. Both the switches 11 and 12 and the display unit 13 face an opening formed in the lower front portion of the main body case 1, and these openings are covered with a thin decorative sheet 14 attached to the main body case 1 from the outer surface side. ing. As for the decorative sheet 14, at least the part facing the display unit 13 has translucency.

  As shown in FIGS. 2 and 3, a front U-shaped mounting portion 17 to which the skin contact body 2 is mounted protrudes from the front upper portion of the main body case 1. The mounting portion 17 includes a loading groove 18 whose front surface and upper surface are opened. The skin contact body 2 is attached to and detached from the main body case 1 by inserting and removing the skin contact body 2 from the upper surface opening. be able to. On the left and right surfaces of the loading groove 18, protrusions 19 extending in the vertical direction are formed, and on the left and right side surfaces of the skin contact body 2, insertion grooves 20 that engage with the protrusions 19 are formed. . At the upper end of the front surface of the main body case 1, a lock tool 21 for maintaining the skin contact body 2 in the mounted state is provided. The locking device 21 is assembled to the main body case 1 so as to be movable back and forth, and is urged to move forward by a spring 22 incorporated in the main body case 1.

  When the upper end of the protrusion 19 is inserted into the lower end of the insertion groove 20 of the skin contact body 2 and the skin contact body 2 is slid downward along the left and right surfaces of the loading groove 18, the skin contact body 2 is attached to the mounting portion 17. Can be attached to. During the mounting operation, the lock 21 and the Peltier unit 3 are pushed backward by the skin contact body 2. When the entire skin contact body 2 passes through the front of the lock tool 21, the lock tool 21 is urged by the spring 22 to return to the front, and engages with a step portion 24 formed on the upper edge of the skin contact body 2. . Due to the engagement of the locking device 21 and the stepped portion 24, the upward contact of the skin contact body 2 is restricted. When removing the skin contact body 2 from the mounting portion 17, the skin contact body 2 is slid upward in a state where the lock tool 21 is moved backward against the biasing force of the spring 22, and the upper surface opening of the loading groove 18 is opened. The skin contact body 2 is extracted from.

  The skin contact body 2 includes a heat receiving body 28 that receives heat or cold from the Peltier unit 3, six spherical balls (rolling bodies) 29 that are supported by the heat receiving body 28 so as to be freely rotatable, and a heat receiving body 28. The ball cover 30 is configured to cooperate to hold the ball 29. The heat receiving body 28 as a whole is formed in a square block shape whose front and rear dimensions are smaller than the vertical and horizontal dimensions. The aforementioned insertion groove 20 is formed on the left and right side surfaces of the heat receiving body 28, and the step portion 24 is formed on the upper corner of the rear surface of the heat receiving body 28. A heat transfer wall 31 facing the Peltier unit 3 is provided on the rear surface side of the heat receiver 28, and the heat receiving surface 32 of the wall 31 is in close contact with the heat supply surface 49 on the front surface of the Peltier unit 3. Accepts heat or cold.

  The balls 29 are arranged in a lattice pattern of three in the vertical direction and two in the horizontal direction on the front side of the skin contact body 2. Specifically, the same number of receiving recesses 35 as the balls 29, that is, six receiving recesses 35 are formed on the front surface of the heat receiving body 28, and one ball 29 is stored in each receiving recess 35. The ball cover 30 includes a rectangular frame-shaped peripheral frame 36 that extends along the peripheral edge of the front surface of the heat receiving body 28, and six ring-shaped holding frames 37 that are disposed along the front edge of each housing recess 35. As shown in FIG. 4, the inner diameter of each holding frame 37 is smaller than the diameter R of the ball 29. The inner peripheral edge of each holding frame 37 is in contact with the front surface of the ball 29 over the entire circumference, and the front end of the ball 29 projects forward from the inside of the holding frame 37. A ball holding recess 38 having a smaller diameter than the recess 35 is formed on the inner back surface of each receiving recess 35, and the periphery of the ball holding recess 38 abuts the surface of the rear portion of the ball 29 over the entire circumference. ing. In this way, by supporting the front and rear surfaces of the ball 29 with the peripheral edges of the holding frame 37 and the ball holding recess 38, the ball 29 in all directions (front and rear direction, left and right direction and up and down direction) with respect to the heat receiving body 28 and the ball cover 30. Movement is restricted. Each ball 29 is housed in the housing recess 35 in such a state that it can only rotate in all directions (rotation around the center of the ball 29).

  The ball holding recess 38 is provided on the inner back surface of the receiving recess 35, and the ball 29 is supported by the edge of the recess 38. The reason why the receiving recess 35 and the ball 29 are in a line contact state is that the ball 29 rotates when the ball 29 rotates. This is to reduce dynamic resistance. The holding frame 37 and the ball 29 are also in a line contact state so that a large sliding resistance is not generated between the both 37 and 29. On the other hand, if the contact area between the housing recess 35 and the ball 29 is reduced, the heat conduction efficiency from the heat receiving body 28 to the ball 29 is reduced. To compensate for this, the inner back corner of the ball holding recess 38 is not provided. It was formed in a partial spherical shape, and the inner and inner corners of the accommodation recess 35 facing the rear half of the ball 29 were also formed in a partial spherical shape. Thereby, since the space | interval of the inner back corner part of the ball | bowl holding | maintenance recessed part 38 and the accommodation recessed part 35 and the surface of the ball | bowl 29 can be made small and the layer of the air interposed in between can be made thin, The heat conduction efficiency can be improved.

  The depth dimension T1 of the ball holding recess 38 is set to be smaller than the distance T2 in the front-rear direction from the heat receiving surface 32 to the inner back surface of the ball holding recess 38 (T1 <T2). The depth dimension T1 is set smaller than the radius of the ball 29 (T1 <R / 2). Thus, by reducing the depth dimension T1 of the ball holding recess 38, the distance between the wall surface of the ball holding recess 38 and the surface of the ball 29 can be reduced, and the air layer interposed therebetween can be made thinner. Therefore, the efficiency of heat conduction to the ball 29 can be improved. The distance T3 (T3 = T1 + T2) in the front-rear direction from the heat receiving surface 32 to the inner back surface of the housing recess 35, that is, the front-rear thickness of the heat transfer wall 31 is set smaller than the diameter R of the ball 29. As a result, the heat transfer wall 31 can be made thin, the heat receiving body 28 can be reduced in weight, and the heat of the Peltier unit 3 can be quickly transferred to the inner back surface of the housing recess 35 and the wall surface of the ball holding recess 38.

  In FIG. 2, each holding frame 37 of the ball cover 30 is connected to the upper and lower horizontal frames of the holding frame 37 or the peripheral frame 36 adjacent to each other in the vertical direction. A vertically long window portion 41 surrounded by the holding frame 37 is formed. From each window part 41, the front surface of the heat receiving body 28 is exposed, and the said front surface comprises the skin stimulation surface 42 which provides thermal stimulation to the skin surface. Since a part of the heat conducted from the Peltier unit 3 to the heat receiving body 28 is conducted to the ball cover 30, the front surface of the ball cover 30 also constitutes the skin stimulation surface 43. The skin 28 and 43 of the heat receiving body 28 and the ball cover 30 are flush with each other (see FIG. 4). Each of the heat receiving body 28, the ball 29, and the ball cover 30 constituting the skin contact body 2 can be formed of a metal material having high thermal conductivity. Specific examples of the metal material include titanium, aluminum, and alloys thereof. Can be mentioned. The heat receiving body 28 can be formed by cutting a die-cast molded product or an extruded molded product.

  The ball cover 30 may be formed from a plastic material. In this case, the ball cover 30 can be manufactured at a lower cost than that made of metal, and the design can be improved by applying various coloring. There is also an advantage that a plurality of types of beauty instruments having different designs of the ball cover 30 can be easily serialized. On the other hand, since the plastic ball cover 30 is inferior in thermal conductivity to the metal heat receiving body 28 and the ball 29, in this case, the ratio of the skin stimulation surface 43 occupying the front surface of the skin contact body 2 is reduced. Instead, it is preferable to increase the ratio of the skin stimulation surface 42 and the balls 29 of the heat receiver 28. As will be described later, the skin stimulation surface 43 of the metal ball cover 30 functions as a current supply surface that applies current stimulation to the skin surface, similarly to the skin stimulation surface 42 and the ball 29 of the heat receiving body 28. The skin stimulation surface 43 when the ball cover 30 is formed of a plastic material does not function as a current supply surface.

  3 and 4, the Peltier unit 3 includes a rectangular Peltier element 45 arranged with the heat generation surface and the heat absorption surface facing forward, a rectangular frame-shaped element holder 46 surrounding the periphery of the Peltier element 45, and a Peltier element The heat transfer plate 47 is in the form of a rectangular plate placed in close contact with the front surface of 45 and the heat sink 48 placed in close contact with the rear surface of the Peltier element 45. The heat transfer plate 47 and the heat sink 48 are made of a metal material such as aluminum having a high thermal conductivity. The front surface of the heat transfer plate 47 constitutes a heat supply surface 49 that is in close contact with the heat receiving surface 32 of the skin contact body 2. The upper and lower portions of the rear surface of the heat sink 48 are urged forward by the spring 6 described above, and in a state where the skin contact body 2 is separated, the upper and lower ends of the heat sink 48 are a pair of upper and lower provided on the main body case 1. By being received by the stopper 50, further forward movement of the Peltier unit 3 is restricted. The upper stopper 50 also serves as a spring receiver that receives the rear end of the spring 22 for the locking device 21.

  In FIG. 1, a fan 53 for supplying heat exchange air to the heat sink 48 is disposed behind the heat sink 48, and the rear wall upper portion of the main body case 1 facing the fan 53 and the bottom wall of the main body case 1. Are formed with vents 54 and 55 each having a mesh-like filter. When the fan 53 is driven, air is taken into the main body case 1 from the lower vent 55 provided in the bottom wall, and the heat-exchanged air that has passed through the heat sink 48 passes through the upper vent 54 provided in the upper portion of the rear wall. It is discharged out of case 1. It is also possible to rotate the fan 53 in the reverse direction to suck air from the upper vent 54 and exhaust air from the lower vent 55.

  When a driving current is supplied to the Peltier element 45 to generate heat on the front surface, the skin contact body 2 can be heated via the heat transfer plate 47. In this case, the rear surface of the Peltier element 45 becomes an endothermic surface, and cold heat is released into the air through the heat sink 48. When the drive current supplied to the Peltier element 45 is reversed and the front surface of the element 45 is a heat absorbing surface, the skin contact body 2 can be cooled via the heat transfer plate 47. In this case, the rear surface of the Peltier element 45 becomes a heat generating surface, and the heat is released into the air through the heat sink 48. At this time, by driving the fan 53, heat exchange between the heat sink 48 and air can be promoted.

  The skin contact body 2 according to the present embodiment also functions as a skin electrode that supplies a weak skin stimulation current to the skin surface. On the control board 10 described above, a current adjustment circuit for generating a pulse current is mounted, and the circuit and the skin contact body 2 are electrically connected. Specifically, the lead-out end of the lead wire (not shown) derived from the current adjustment circuit is connected to the rear surface of the heat transfer plate 47 of the Peltier unit 3, and the pulse current generated by the current adjustment circuit is the lead wire. And supplied to the skin contact body 2 through the heat transfer plate 47. The lead wire lead-out end is connected to the rear surface of the heat transfer plate 47 in order to prevent the lead wire from being exposed to the outer surface of the main body case 1 when the skin contact body 2 is removed from the mounting portion 17. A grip electrode 58 to which a pulse current having a polarity opposite to that of the skin contact body 2 is supplied is exposed on the rear surface of the main body case 1 and on the left and right side surfaces, and a current adjusting circuit for the grip electrode 58 and the control board 10 is exposed. Are also connected by lead wires (not shown).

  As shown in FIG. 3, an ion generator 59 is built in the main body case 1 so as to face the upper vent 54. The ion generator 59 includes a needle-like discharge electrode 60 and a ring-shaped counter electrode 61 surrounding the discharge electrode 60. When a high voltage is applied between the electrodes 60 and 61, the ion generator 59 generates corona discharge. In this configuration, electrons are emitted from the discharge electrode 60. The emitted electrons combine with oxygen molecules present in the space to become ionic species (negative or positive charged molecular species), and ions (negative ions or positive ions) when water molecules bind to these ionic species. ) This ion has the effect of adhering to hair and skin and increasing its water content. The ions are released from the upper vent 54 to the outside of the main body case 1 on the wind generated by the fan 53. The filter attached to the upper vent 54 has a relatively large mesh so as not to inhibit the release of ions. On the other hand, since the mesh is formed smaller than the thickness of the finger, it is possible to prevent the fingertip from accidentally touching the ion generator 59 or the fan 53 with a filter, and thus the safety of the beauty tool is ensured. ing.

  The beauty tool according to the present embodiment starts to be driven by a single operation of the power switch 11 and stops when the switch 11 is operated again. Specifically, as shown in FIG. 5, when the power switch 11 is pressed while the beauty tool is stopped, a drive current is supplied from the control board 10 to the Peltier element 45, the fan 53, and the ion generator 59, A pulse current is supplied to the skin contact body 2 and the grip electrode 58. When the power switch 11 is pressed in the driving state of the beauty tool, the supply of all the driving current and pulse current is stopped. In addition, the beauty tool according to the present embodiment includes a “heat mode” for heating the skin contact body 2, a “cooling mode” for cooling the skin contact body 2, and an “ion introduction mode” for negatively charging the skin contact body 2, In addition, it is possible to operate in the “ion derivation mode” in which the skin contact body 2 is positively charged, and the user selects one of the thermal mode and the thermal mode, and selects one of the ion introduction mode and the ion derivation mode. Can do. Specifically, the operation mode is switched in the order of “thermal / ion introduction mode”, “cooling / ion introduction mode”, “thermal / ion derivation mode”, and “cooling / ion derivation mode” by pressing the mode switch 12. be able to. The four LEDs constituting the display unit 13 indicate, from the top, the heating mode, the cooling mode, the ion introduction mode, and the ion derivation mode, and the two LEDs corresponding to the selected operation mode are lit. It has become.

  In the thermal / ion introduction mode, a drive current is supplied from the control board 10 to the Peltier element 45, the fan 53, and the ion generator 59, a negative polarity pulse current is supplied to the skin contact body 2, and the grip electrode 58 is positively added. A polarity pulse current is supplied (see FIG. 5). In this operation mode, the front surface of the Peltier element 45 is a heat generating surface, and the heat is conducted to the skin contact body 2 through the heat transfer plate 47. Cold heat generated from the rear surface (heat absorption surface) of the Peltier element 45 is conducted to the heat sink 48 and is released into the air by heat exchange air generated by the fan 53. In the skin contact body 2, the heat is first conducted from the heat receiving surface 32 to the heat transfer wall 31, and then the heat is conducted to the front portion of the heat receiving body 28, the ball 29, and the ball cover 30.

  Grasping the lower half of the main body case 1, pressing the front surface of the heated skin contact body 2 against the skin surface, and reciprocating along the skin surface, the ball 29 rolls on the skin surface and the skin surface Pressure stimulation and thermal stimulation can be applied to the skin, and at the same time, the skin surface can be rubbed with the skin stimulation surfaces 42 and 43 around the ball 29 to apply pressure stimulation and thermal stimulation to the skin surface. Furthermore, current stimulation can be applied to the skin surface by a negative polarity pulse current supplied to the skin contact body 2. Current stimulation to the skin surface is performed by supplying current to the skin surface from the surface of the ball 29 and the skin stimulation surfaces 42 and 43. If a cosmetic liquid such as a skin lotion is applied to the skin surface, the moisturizing effect can be enhanced by allowing the cosmetic liquid to penetrate the skin surface.

  On the other hand, the air around the ion generator 59 is cooled by the heat sink 48 and becomes air having a temperature lower than room temperature. This air has a higher relative humidity than the surroundings, and the proportion of water molecules in the air is large. That is, ion species generated around the ion generator 59 are likely to bind to water molecules, and therefore ions are difficult to disappear for a long time. The generated ions are carried from the upper vent 54 to the outside of the main body case 1 by wind at a temperature lower than room temperature. When ions are carried by low-temperature wind, the thermal kinetic energy of the ions is reduced, and the water molecules that make up the ions can be prevented from being dispersed as much as possible, thus preventing the disappearance of ions over a long period of time. . Thereby, the reach | attainment distance of ion becomes long and more ions can be made to adhere to hair and skin. When taking care of a beauty target (skin, hair, scalp, etc.) with these ions (increasing the amount of moisture), it is preferable to change the main body case 1 serving as a grip so that the upper vent 54 faces the beauty target.

  In the cooling / ion introduction mode, the current supplied to the Peltier element 45 is in the opposite direction to the above-described heating / ion introduction mode, and the front surface of the element 45 becomes the endothermic surface and the skin contact body 2 is cooled. The When the front surface of the skin contact body 2 is pressed against the skin surface and reciprocated along the skin surface, pressure stimulation and cooling stimulation by the ball 29 and the skin stimulation surfaces 42 and 43 can be applied to the skin surface. The heat generated from the rear surface (heat generating surface) of the Peltier element 45 is conducted to the heat sink 48 and is released into the air by the heat exchange air generated by the fan 53. The heat exchange air that passes through the heat sink 48 and blows out from the upper vent 54 is air that is hotter than room temperature, and contains ions as in the case of the thermal / ion introduction mode. Accordingly, when the beauty appliance is driven with the upper vent 54 facing the beauty object (skin, hair, scalp, etc.), it can be cared for (heat amount is increased) while applying a thermal stimulus to the beauty object. . The other points are the same as the thermal / ion introduction mode.

  In the thermal / ion derivation mode, the pulse current supplied to the skin contact body 2 and the grip electrode 58 is in the opposite direction to the above-described thermal / ion introduction mode. That is, a positive polarity pulse current is supplied to the skin contact body 2, and a negative polarity pulse current is supplied to the grip electrode 58. When a positive polarity pulse current is supplied to the skin contact body 2, current stimulation can be applied to the skin surface and fine dirt entering the pores of the skin surface can be adsorbed. In addition, negative ions generated by the ion generator 59 are attracted to the positively charged skin surface by pressing the skin contact body 2. The negative ions generated by the ion generator 59 are released from the upper vent 54 out of the main body case 1 on the heat exchange air, and then are applied to the skin surface along the lines of electric force formed toward the skin surface. Attracted. The other points are the same as the thermal / ion introduction mode. The description of the cooling / ion derivation mode is omitted. Also in the thermal / ion derivation mode and the cold / ion derivation mode, ions having an effect of increasing the amount of water are generated around the ion generator 59 and are generated from the upper vent 54 as in the previous thermal / ion introduction mode. Released. However, in the ion derivation mode, since negative ions are attracted to the positively charged skin surface, it is not always necessary to change the main body case 1 to face the upper vent 54.

  As described above, according to the beauty instrument according to the present embodiment, the ball 29 is rolled on the skin surface to apply pressure stimulation, and the ball 29 is subjected to thermal stimulation (thermal stimulation or Cold stimulation can be applied, and at the same time, the skin surface can be rubbed with the skin stimulation surfaces 42 and 43 around the ball 29 to apply pressure stimulation and thermal stimulation to the skin surface. Furthermore, current stimulation can be applied to the skin surface by a pulse current supplied to the skin contact body 2, and a cosmetic treatment of ion introduction or ion derivation can be performed. As described above, according to the beauty tool according to the present embodiment, various stimuli can be applied as compared with the conventional beauty tool that applies only the pressure stimulus to the skin surface, and thus the beauty process is effectively performed. be able to.

(2nd Example) FIG.6 and FIG.7 has shown 2nd Example of the beauty tool based on this invention, and the structure of the skin contact body 2 differs from 1st Example. In this embodiment, a pair of upper and lower lids 62 and 63 are prepared instead of the ball cover 30 of the first embodiment, and the skin contact body 2 is constituted by the lids 62 and 63, the heat receiving body 28 and the six balls 29. . On the front surface of the heat receiving body 28, a pair of left and right vertically accommodating recesses 35 are provided, and three balls 29 are accommodated in each of the recesses 35. The heat receiving body 28 and the housing recess 35 have a vertical dimension equal to three times the diameter R of the ball 29. A ball holding recess 38 formed of a vertically long groove is provided on the inner back surface of each receiving recess 35. The heat receiving body 28 is made of an extruded product, and the housing recess 35 and the ball holding recess 38 are formed over the entire length of the heat receiving body 28 in the vertical direction. A vertically long rectangular ball window 64 is formed at the front end of the housing recess 35, and the front end of each ball 29 is exposed outward from the ball window 64. Since the left and right widths of the ball window 64 are set to be smaller than the diameter R of the ball 29, each ball 29 does not escape forward from the ball window 64.

  On the upper and lower surfaces of the heat receiving body 28, insertion holes 65 for inserting the balls 29 into the receiving recesses 35 are formed. When three balls 29 are inserted into the receiving recesses 35 from the insertion openings 65 and the lids 62 and 63 are fixed to the upper and lower surfaces of the heat receiving body 28 to close the insertion openings 65, the balls 29 are sealed in the receiving recesses 35. Thus, the skin contact body 2 according to the present embodiment can be obtained. A pair of left and right fixing protrusions 66 for fixing the lids 62 and 63 to the heat receiving body 28 protrude from the inner surfaces of the lids 62 and 63 (surfaces facing the heat receiving body 28). A vertically long insertion groove 67 into which the fixing protrusion 66 is inserted is formed on the side surface. The insertion groove 20 that engages with the protrusion 19 of the mounting portion 17 includes a long groove 20a formed on the left and right side surfaces of the heat receiving body 28 and a short groove 20b formed on the left and right end portions of the lids 62 and 63. The The fitting groove 67 and the long groove 20a are also formed over the entire length of the heat receiving body 28 in the vertical direction. The step portion 24 that engages with the locking device 21 is formed at the upper corner of the rear surface of the upper lid 62.

  As shown in FIG. 6A, each ball 29 is accommodated in the accommodating recess 35 in a state of abutting with the vertically adjacent balls 29, and the upper and lower three balls 29 are vertically moved by a pair of upper and lower lids 62 and 63. The vertical movement of each ball 29 with respect to the heat receiving body 28 is restricted. In addition, two left and right portions of the front portion of each ball 29 abut on the edge of the ball window 64 (point contact), and two left and right portions of the rear portion abut on the edge of the ball holding recess 38 (point contact). The play of each ball 29 in the horizontal direction (front-rear direction and left-right direction) with respect to the heat receiving body 28 is restricted. Each ball 29 is accommodated in the accommodating recess 35 in a state where only the rotation in all directions is possible. The pair of upper and lower lids 62 and 63 are in contact with the balls 29 with a force that does not prevent the rotation of the balls 29 by pressing them. Since others are the same as those of the first embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted.

  As a modification of the present embodiment, a vertical restricting projection that abuts the ball 29 is provided on the inner surface of at least one of the lids 62 and 63, and the vertical movement of the ball 29 can be regulated by the projection. . In this case, the heat receiving body 28 and the housing recess 35 have a vertical dimension larger than three times the diameter R of the ball 29. In the form in which the ball 29 is in direct contact with the inner surfaces of the lids 62 and 63, when the lids 62 and 63 are curved and deformed outwardly over time, the balls 29 come into surface contact with the lids 62 and 63 to cause sliding resistance. However, in the embodiment in which the restricting protrusion is brought into contact with the ball 29, the ball 29 is in point contact with the restricting protrusion even when the lids 62 and 63 are curved and deformed outwardly. The sliding resistance does not increase.

(3rd Example) FIG. 8 and FIG. 9 has shown 3rd Example of the beauty tool which concerns on this invention, and the structure of the skin contact body 2 is a little different from 2nd Example. Specifically, the insertion port 65 is formed only on the lower surface of the heat receiving member 28, and the lid 63 that closes the insertion port 65 is fixed only on the lower surface of the heat receiving member 28. In addition, the transverse cross section of each receiving recess 35 is formed in a dominant arc shape slightly larger in diameter than the ball 29 so as to allow slight movement of each ball 29 in the receiving recess 35. However, since the left and right widths of the ball window 64 are set to be smaller than the diameter R of the ball 29, each ball 29 does not escape forward from the ball window 64. When the diameters of the ball 29 and the housing recess 35 are made different, the surface of the ball 29 and the wall surface of the housing recess 35 are in a point contact state, and the sliding resistance when the ball 29 is idle can be reduced. The ball holding recess 38 according to the second embodiment is omitted. Since others are the same as those of the second embodiment, the same reference numerals are assigned to the same members and the description thereof is omitted.

After forming, the heat receiving surface 32 and the heat supply surface 49 were constituted by uneven surfaces. If the heat receiving surface 32 and the heat supply surface 49 are configured as an uneven surface, the heat transfer area of the heat receiving body 28 and the heat transfer plate 47 can be increased as compared with the case where both surfaces 32 and 49 are flat surfaces. The heat transfer efficiency from the heat plate 47 to the heat receiving body 28, that is, from the Peltier unit 3 to the skin contact body 2 can be improved. Since others are the same as those of the first embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted.

The heat transfer convex portion 70 and the heat transfer concave portion 71 according to the present invention may be in close contact with each other only as in this embodiment, or may be entirely opposed to each other with a gap between them. May be in close contact with each other. When the heat transfer convex portion 70 and the heat transfer concave portion 71 are brought into close contact with each other without a gap, the efficiency of heat conduction from the heat transfer plate 47 to the heat receiving body 28 can be further improved. As a modification of the present embodiment, the heat transfer concave portion 71 can be formed on the heat transfer plate 47, and the heat transfer convex portion 70 can be formed on the heat receiving body 28. Further, the heat transfer convex portions 70 and the heat transfer concave portions 71 can be alternately formed on the heat transfer plate 47 and the heat receiving body 28. The cross-sectional shape of the heat transfer convex portion 70 and the heat transfer concave portion 71 is not limited to a polygonal shape such as a trapezoid, but may be a shape including a curved line such as a semicircular shape or a bow shape.

The heat transfer plate 47 is locked to the peripheral edge portion of the heat transfer window 5 as in the fifth embodiment, and thereby the relative movement of the Peltier unit 3 with respect to the main body case 1 is restricted. The mounting portion 17 of the main body case 1 is formed of a cylindrical wall that opens forward, and the inner diameter of the mounting portion 17 is slightly larger than the outer diameter of the heat receiving body 28. When the rear portion of the skin contact body 2 is inserted into the mounting portion 17 and rotated clockwise with respect to the Peltier unit 3, the screw shaft 83 is screwed into the screw hole 82 and the skin contact body 2 is mounted and fixed to the mounting portion 17. be able to. When the attached skin contact body 2 is rotated counterclockwise, the screw shaft 83 is separated from the screw hole 82 and the skin contact body 2 can be removed from the attachment portion 17.

  In the mounted state of the skin contact body 2, the peripheral surface of the screw shaft 83 is in close contact with the peripheral surface of the screw hole 82, and the front end surface of the screw shaft 83 is opposed to the rear end portion of the ball 29 with a slight gap. . Accordingly, the heat conducted from the Peltier element 45 to the screw shaft 83 through the heat transfer plate 47 is conducted from the peripheral surface of the screw shaft 83 to the peripheral surface of the screw hole 82 and from the tip surface of the screw shaft 83 through the air. And is conducted to the surface of the ball 29. The screw shaft 83 and the screw hole 82 also serve as the heat transfer convex portion 70 and the heat transfer concave portion 71 described in the fourth embodiment. A space surrounded by the tip surface of the screw shaft 83 and the screw hole 82 constitutes a ball holding recess 38 for the ball 29. The heat conducted from the heat transfer plate 47 to the screw shaft 83 is only a part of the heat conducted from the Peltier element 45 to the heat transfer plate 47, and most of the heat conducted to the heat transfer plate 47 is the heat transfer plate 47. To the heat receiving body 28. Since others are the same as those of the first embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted. Also in this embodiment, since the Peltier unit 3 is fixed to the main body case 1 in the same manner as the fifth embodiment, the Peltier unit 3 is damaged or poor conduction occurs between the Peltier unit 3 and the control board 10. Can be well prevented.

(Seventh Embodiment) FIG. 13 shows a beauty tool according to a seventh embodiment of the present invention. The skin contact body 2 is attached and detached via a bayonet structure provided between the skin contact body 2 and the mounting portion 17. This is different from the sixth embodiment. The bayonet structure includes a pair of bayonet claws 86 provided on the heat receiving body 28 of the skin contact body 2 and an annular bayonet wall 87 provided on the mounting portion 17. Specifically, the bayonet claws 86 project from the opposing positions on the peripheral surface of the disk-shaped heat receiving body 28, respectively. The bayonet wall 87 is formed inwardly at the front end of the mounting portion 17 formed of a cylindrical wall, and grooves 88 for allowing the bayonet claws 86 to pass back and forth are formed at positions opposed to the inner peripheral edge thereof.

  The Peltier unit 3 is assembled so as to be movable back and forth with respect to the main body case 1 in the same manner as in the first embodiment. The pair of left and right springs 6 incorporated in the main body case 1 moves forward, that is, the skin contact body 2. It is urging closely toward. A round shaft-shaped heat transfer convex portion 70 projects from the center of the front surface of the heat transfer plate 47 of the Peltier unit 3, and a round hole that engages the heat transfer convex portion 70 at the center of the rear surface of the heat receiving body 28. A heat transfer recess 71 is formed. The heat transfer concave portion 71 communicates with the housing concave portion 35 in the front-rear direction, and the front end surface of the heat transfer convex portion 70 faces the rear end portion of the ball 29 with a slight gap. In the mounted state of the skin contact body 2, a space surrounded by the tip surface of the heat transfer convex portion 70 and the heat transfer concave portion 71 constitutes a ball holding concave portion 38 for the ball 29.

  In order to attach the skin contact body 2 to the mounting portion 17, the bayonet claw 86 and the groove 88 are aligned in the circumferential direction, and the skin contact body 2 is inserted into the mounting portion 17 from the front. After passing, the skin contact body 2 is rotated to one side. Thereby, both the bayonet claws 86 are positioned behind the bayonet wall 87, and the skin contact body 2 can be prevented from coming out forward. In order to remove the skin contact body 2 from the mounting part 17, the skin contact body 2 is rotated in the direction opposite to that when the skin contact body 2 is mounted, and the circumferential position of the bayonet claw 86 and the groove 88 is aligned.

It is accepted. That is, the skin contact body 2 is float-supported by the spring 6 integrally with the Peltier unit 3. When the skin contact body 2 is floated back and forth, it becomes easy to make the skin contact body 2 conform to the unevenness of the skin surface, thereby reducing the load and stress on the skin surface. Since others are the same as in the sixth embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.

(Eighth Embodiment) FIGS. 14 to 17 show an eighth embodiment of a beauty instrument according to the present invention, in which an attachment 90 including a skin contact body 2 and a Peltier unit 3 is detachably attached to the main body case 1. The point of attaching to is greatly different from the first embodiment. The electrical component unit 4 is housed in the main body case 1, and the supply of drive current from the electrical component unit 4 to the Peltier unit 3 and the supply of pulse current from the electrical component unit 4 to the skin contact body 2 will be described later. This is performed via the connector groups 96 and 97.

  The attachment 90A according to the present embodiment includes a box-shaped head case 91 to which the skin contact body 2 and the Peltier unit 3 are assembled. As shown in FIG. 16, a head opening 92 is formed in the front wall of the head case 91, and the front portion of the skin contact body 2 is exposed outward from the head opening 92. The Peltier unit 3 is disposed behind the skin contact body 2 and is entirely accommodated in the head case 91. The front surface (heat supply surface 49) of the heat transfer plate 47 of the Peltier unit 3 and the rear surface (heat reception surface 32) of the heat receiving body 28 of the skin contact body 2 are in close contact with each other in front and back. In the present embodiment, the Peltier unit 3 is fixed to the skin contact body 2 so that the both surfaces 49 and 32 are brought into close contact with each other, and the heat transfer from the heat transfer plate 47 to the heat receiving body 28 can be performed satisfactorily. A head vent 93 having a mesh-like filter is formed on the rear wall of the head case 91 facing the heat sink 48 in the front-rear direction. The fan 53 and the ion generator 59 disposed behind the heat sink 48 in the first embodiment are not shown.

  A square cylindrical mounting recess 94 that opens downward is formed at the lower end of the head case 91, and a mounting projection 95 that can be engaged with the mounting recess 94 is formed at the upper end of the main body case 1. It is. Connector groups 96 and 97 including three connectors 96 </ b> A to 96 </ b> C and 97 </ b> A to 97 </ b> C are provided on the upper and lower walls of the mounting recess 94 and the mounting protrusion 95, respectively. In this embodiment, the connectors 96A to 96C on the mounting concave portion 94 side are male, and the connectors 97A to 97C on the mounting convex portion 95 are female. Of the three pairs, two pairs of connectors 96A, 97A, 96B, and 97B electrically connect the Peltier element 45 and the control board 10, and the other pair of connectors 96C and 97C are skin contact bodies 2 that also serve as skin electrodes. And the control board 10 (current adjustment circuit) are electrically connected (see FIG. 17). The lead wire 106 extending from the pulse current supply connector 96C is connected to the heat transfer plate 47, and the pulse current is supplied from the lead wire 106 to the skin contact body 2 via the heat transfer plate 47. In the skin contact body 2, the pulse current is supplied from the heat receiving body 28 to the skin surface through the ball 29, or from the heat receiving body 28 to the skin surface through the ball cover 30, or from the skin stimulation surface 42 of the heat receiving body 28 to the skin surface. Supplied. However, as described in the first embodiment, the ball cover 30 can be formed of a plastic material in consideration of cost and design. Since no current flows in the ball cover 30 in this case, the pulse current Is supplied to the skin surface from the heat receiving body 28 through the ball 29 or from the skin stimulation surface 42 of the heat receiving body 28.

  When the mounting concave portion 94 is externally fitted to the mounting convex portion 95, the male connectors 96A to 96C are connected to the corresponding female connectors 97A to 97C. Further, the lock tool 98 incorporated in the main body case 1 penetrates the cylindrical wall of the mounting convex portion 95 outwardly, and engages with a lock hole 99 provided in the cylindrical wall of the mounting concave portion 94, thereby the main body. The mounting state of the head case 91 with respect to the case 1 is maintained. Since others are the same as those of the first embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted.

Ninth Embodiment FIGS. 18 to 20 show a ninth embodiment of the present invention in which the structure of the attachment 90 is changed. The skin contact body 2 of the attachment 90 </ b> B according to the present embodiment includes a disk-shaped heat receiving body 28 disposed inside the head opening 92 of the head case 91, and a front surface side of the heat receiving body 28. The ball cover 30 is exposed to the outer side, and the three balls 29 held between the heat receiving body 28 and the ball cover 30 are configured. Three ball windows 102 having a smaller diameter than the ball 29 are formed on the front wall of the ball cover 30, and the front end portion of the ball 29 protrudes forward from each ball window 102.

  Specifically, the ball cover 30 is formed in a round dish shape whose rear surface is open, and the open end, that is, the rear end, is in close contact with the front surface of the heat receiving body 28. Thereby, heat conduction from the heat receiving body 28 to the ball cover 30 is favorably performed. Each of the heat receiving body 28, the ball 29, and the ball cover 30 constituting the skin contact body 2 is made of a metal material having a high thermal conductivity, as in the first embodiment. The front surface of the ball cover 30 constitutes a skin stimulation surface 43, and a part of the heat or cold conducted from the heat receiving body 28 to the ball cover 30 is released from the skin stimulation surface 43.

  In the heat receiving body 28, three through holes 103 having a smaller diameter than the balls 29 are formed corresponding to the three balls 29. Each through-hole 103 accommodates a spring 104 that supports the ball 29 and moves and urges it toward the front (outward) ball window 102. Each spring 104 is formed of a metal coil spring having conductivity, and its front and rear ends are each formed in a ring shape. The ring-shaped portion at the rear end of the spring 104 is received on the front surface of the heat transfer plate 47. The ring-shaped portion at the front end of the spring 104 constitutes a seat for receiving the rear end portion of the ball 29, and supports the ball 29 in a state where the entire length is in contact with the surface of the rear portion of the ball 29, that is, in a line contact state. To do. In this embodiment, the ring-shaped part is formed in a perfect circle. More precisely, the end of the metal wire constituting the spring 104 is formed in a dominant arc shape having a slight gap in the circumferential direction. The ring shape is not limited to a perfect circle, but is a concept including a non-perfect circle such as a superior arc in which a part of the circumference is divided or an ellipse. If the rear end portion of the ball 29 fits into the ring-shaped portion of the spring 104, the posture of the ball 29 can be stabilized. Further, if the ring 104 is provided on the spring 104 to directly support the ball 29, it is not necessary to interpose a member for supporting the ball 29 between the spring 104 and the cost can be reduced accordingly.

  In a normal state, the ball 29 is received at the periphery of the ball window 102 provided in the ball cover 30. When the ball 29 comes into contact with the skin surface or the like and is pushed backward (inward), the ball 29 is received by a front spreading taper receiving seat 105 formed at the front end of the through-hole 103. That is, the ball 29 can float back and forth by a gap in the front-rear direction between the ball 29 and the seat 105 in a normal state. If the ball 29 is supported in such a manner that it can float, the ball 29 can be sunk inward even if it is strongly pressed against the skin surface, so that the contact feeling of the ball 29 with the skin surface should be soft and gentle. Can do.

  Each spring 104 functions as a heat transfer body that conducts heat of the heat transfer plate 47 to the balls 29 and also functions as a pulse current supply body. Each spring 104 is connected to a lead wire 106 extending from one connector 96 </ b> C provided in the mounting recess 94. A connector 97 </ b> C on the mounting convex portion 95 side that is paired with the connector 96 </ b> C is electrically connected to a current adjustment circuit that generates a pulse current mounted on the control board 10. Therefore, the pulse current generated by the current adjustment circuit of the control board 10 is supplied from the male and female connectors 97C and 96C to the ball 29 serving also as the skin electrode through the lead wire 106 and the spring 104 in this order. Since the spring 104 stably adheres to the ball 29 due to its own elasticity, by electrically connecting the lead wire 106 and the ball 29 via the spring 104, poor conduction between the ball 29 and the lead wire 106 is achieved. Can be surely prevented. Since the ball 29 is supported in a line contact state by the ring-shaped portion of the spring 104, the contact state of both the members 29 and 104 can be stabilized, and this also causes a poor conduction between the ball 29 and the lead wire 106. Can be reliably prevented. When the contact state between the two members 29 and 104 is stabilized, heat conduction from the heat transfer plate 47 to the ball 29 via the spring 104 can be performed well. Further, when the ball 29 is completely fitted in the ring-shaped portion of the spring 104, the contact state between the ball 29 and the spring 104 is surely maintained despite the rotation of the ball 29, thereby preventing a poor conduction. Can do.

  The shape connecting the centers of the three balls 29 in the skin stimulation surface 43 is an equilateral triangle, and the interval between the two adjacent balls 29 is the same. When the front surface of the skin contact body 2 according to the present embodiment is pressed against the skin surface and reciprocated along the skin surface, a pressure stimulus is applied to the skin surface by the rolling balls 29, and the adjacent 2 Pressure stimulation is also given to the skin surface by pinching the skin surface with the individual balls 29. Since others are the same as those of the eighth embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted.

  As a modification of the present embodiment, four balls 29 can be arranged on each vertex of a virtual square in the skin stimulation surface 43. In addition, five balls 29 can be arranged on each vertex of a regular pentagon imaginary in the skin stimulation surface 43. Further, six balls 29 can be arranged on each vertex of a regular hexagon virtually within the skin stimulation surface 43.

(Tenth Embodiment) FIG. 21 shows a tenth embodiment of the present invention in which the structure of the attachment 90 is changed. The attachment 90C according to the present embodiment is different from the attachment 90B according to the ninth embodiment in the arrangement of the balls 29 in the skin contact body 2. Specifically, each ball 29 is arranged so that the shape connecting the centers of the four balls 29 becomes a trapezoid. This trapezoid is an isosceles trapezoid whose upper base is longer than the lower base. Comparing the interval between two adjacent balls 29, the interval between the two balls 29 arranged at both ends of the lower bottom (first interval) is the shortest, and then the two balls 29 arranged at both ends of the hypotenuse. The distance between the two balls 29 arranged at both ends of the upper base (third distance) is the longest.

  The two balls 29 adjacent at the first interval can pinch the skin surface relatively strongly, and the two balls 29 adjacent at the second interval can weaken the skin surface with a weaker force. According to the two balls 29 adjacent to each other at the third interval, the skin surface can be pinched with a weaker force. That is, a plurality of pressure stimuli with different strengths can be applied to the skin surface. Since others are the same as those of the ninth embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted.

  In the ninth and tenth embodiments, as shown in FIGS. 18 and 21, the balls 29 are dispersedly arranged on the front surface of the skin contact body 2, and the sum total of the front projected areas of the exposed portions of the balls 29 is determined as the skin stimulation surface 43. It was set sufficiently smaller than the area. Since the pressure stimulus applied to the skin surface by the balls 29 is relatively large, avoiding the crowding of the balls 29 as in both embodiments, the pressure stimulus applied to the skin surface by the entire skin contact body 2 is too strong. There can be no reasonable ones.

Eleventh Embodiment FIGS. 22 to 24 show an eleventh embodiment of the present invention in which the structure of the attachment 90 is changed. The attachment 90D according to the present embodiment is greatly different from the attachments 90A to 90C in that the skin contact body 2 includes a round bottom saddle type roller (rolling element) 109 instead of the ball 29. Specifically, the attachment 90D includes a base body 110 provided with a mounting recess 94, a pair of left and right heater units (heat sources) 111 disposed so as to protrude from the upper surface of the base body 110, and each heater unit 111. And a skin contact body 2 to be covered. Each heater unit 111 is formed in a round bar shape, and the entire skin contact body 2 including the roller 109 is rotatably supported around the central axis of the unit 111. The central axes of the roller 109 and the heater unit 111 coincide with each other, and this central axis functions as the rotation axis P of the roller 109. The rotation axis P of each roller 109 is tilted forward with respect to the central axis Q in the vertical direction of the main body case 1. In this embodiment, the forward tilt angle α of the rotation axis P with respect to the central axis Q is 50 degrees. did. Further, the crossing angle β of the left and right rotation axes P in the plane including the left and right rotation axes P was set to 100 degrees. The entire attachment 90D is symmetric with respect to the central axis Q.

  Next, the structure of the heater unit 111 and the skin contact body 2 will be described. In this description, the center axis of the roller 109 and the heater unit 111 (the rotation axis of the roller 109) is displayed in accordance with the arrows and the vertical display shown in FIG. The extending direction of P) is defined as the vertical direction, and the protruding end side of the roller 109 and the heater unit 111 is defined as the upper side and the proximal end side is defined as the lower side. The heater unit 111 includes an elongated cylindrical heat transfer cylinder 114 that opens downward, and a heater 115 that is housed in the inner part of the heat transfer cylinder 114. The heat transfer cylinder 114 is formed from a metal material having high thermal conductivity and conductivity. A step portion 116 for connecting and fixing the heat transfer tube 114 to the base body 110 is formed at the lower end of the heat transfer tube 114. The heater 115 is connected to connectors 96A and 96B (see FIG. 22) for supplying drive current provided in the mounting recess 94 with lead wires. A lead wire 106 extending from the connector 96C for supplying pulse current is connected to the inner peripheral surface of the heat transfer cylinder 114 (see FIG. 24). That is, the heat transfer cylinder 114 also serves as the internal electrode 117 that receives the supply of the pulse current from the current adjustment circuit of the control board 10.
