  The float structure includes a float frame 96 that surrounds the periphery of the connecting portion 75, and a float shaft 99 that is attached to the connecting portion 75 and supports the float frame 96 so as to be tiltable. A plurality of rubbing bodies 77 and rubbing body holders 76 are provided on the float frame 96.

  The functional head 15 is a thermal stimulation head 15 that can apply thermal stimulation or cold stimulation to the skin surface. With the thermal stimulation head 15 heated to a temperature higher than the temperature of the rubbing body 77 or with the thermal stimulation head 15 cooled to a temperature lower than the temperature of the rubbing body 77, the thermal stimulation head 15 and the rubbing body 77 are placed on the skin surface. By acting simultaneously, heat stimulus and rubbing stimulus are simultaneously given to the skin surface.

  The rubbing body 77 is elastically supported by a float spring 90 provided in the rubbing body holder 76.

  The rubbing body 77 is formed of a sphere that is rotatably supported by the rubbing body holder 76. In a state where the functional head 15 and the rubbing body 77 are simultaneously applied to the skin surface, the functional head 15 gives a strong rubbing stimulus and the rubbing body 77 gives a weak rubbing stimulus.

  The first virtual plane H 1 passing through the top of the rubbing body 77 is positioned above the head virtual plane H passing through the top of the functional head 15.

  The rubbing body 77 is supported by the rubbing body holder 76 so as to be floatable up and down, and is pushed up and biased by the float spring 90. The rubbing body 77 can float up and down between a standby position pushed up by the float spring 90 and a float position pushed down against the biasing force of the float spring 90. In the float position, the second imaginary plane H2 passing through the top of the rubbing body 77 is positioned the same as or below the head imaginary plane H passing through the top of the thermal stimulation head 15.

  The area of the skin contact surface 25 of the functional head 15 is set larger than the area of one rubbing body 77 in plan view.

  A plurality of rubbing bodies 77 made of a spherical body are rotatably supported by a rubbing body holder 76.

  Although the area of one rubbing body 77 in plan view is smaller than the area of the skin contact surface 25 of the functional head 15, the total area of the plurality of rubbing bodies 77 in plan view is the area of the skin contact surface 25 of the functional head 15. It is set larger.

  When comparing the curvature of the skin contact surface 25 of the functional head 15 formed in an upwardly curved shape with the curvature of the rubbing body 77 made of a sphere, the former curvature is set smaller than the latter curvature, and the latter curvature is set larger than the former curvature. It is.

  A rubbing body 77 is rotatably supported by a rubbing body holder 76. The rubbing body 77 is received by a plurality of receiving arms 87 provided integrally with the rubbing body holder 76 and provided at the bottom of the rubbing body holder 76. Thus, the rubbing body 77 is elastically supported by the plurality of receiving arms 87.

  A rubbing body 77 is rotatably supported by a rubbing body holder 76. The rubbing body 77 is received by a plurality of receiving arms 87 provided on the bottom of the rubbing body holder 76, and the peripheral surface of the rubbing body 77 is exposed to the bottom surface side of the rubbing body holder 76.

  In a state where the connection part 75 of the stimulus applying tool B is attached to the attachment part 50, a water passing space S is secured between the bottom surface of the rubbing body holder 76 and the main body case 1.

  The connection part 75 of the stimulus imparting device B is composed of a plurality of connection legs 79, and a water passage opening is provided between the connection legs 79 adjacent in the circumferential direction.

  The functional head 15 is a skin electrode 65 that supplies current to the skin surface. The impregnated body C covering the outer surface of the skin electrode 65 is fixed by the stimulus applying tool B mounted on the mounting portion 50.

  In the small electric appliance according to the present invention, when the rubbing body 114 for applying the rubbing stimulus to the skin surface is provided adjacent to the heat stimulating head 15 for applying the heat stimulus to the skin surface, the heat stimulating head 15 and the rubbing body. 114 can be rubbed and moved simultaneously on the skin surface, and the action of the thermal stimulation head 15 and the rub stimulation can be simultaneously applied to the skin surface. For example, in a state in which a rubbing stimulus is applied by the rubbing body 77 while warming the skin surface with the thermal stimulation head 15, physical stimulation can be applied to the skin surface while promoting blood circulation by the thermal stimulation. Further, in a state in which the thermal stimulation head 15 applies a cold stimulus to the skin surface while applying a thermal stimulus to the skin surface, a physical stimulus can be applied to the skin surface while the facial skin is tightened by the cold thermal stimulus. When the rubbing body 114 is a ball 114 that is rotatably supported, the touch (contact feeling) of the rubbing body 77 on the skin surface can be made soft and gentle.

  In the small electric appliance, by providing the attachment unit 50 with the stimulus imparting tool B that imparts a rubbing stimulus to the skin surface, a rubbing stimulus can be imparted to the skin surface separately from the action of the functional head 15. The phrase “stimulation applicator B is provided in the mounting portion 50” includes a configuration in which the stimulus applicator B is fixed to the mounting portion 50 in an inseparable manner. For example, the functional head 15 or the head 15 is If the supporting case body (a part of the main body case 1) is used as the mounting portion 50 and the stimulating device B is detachably mounted on the mounting portion 50, the stimulating device B is connected to the main body case 1 in a stable state. it can. This is because the structural strength of the mounting portion 50 is strengthened by mounting the mounting portion 50 on the functional head 15 having a higher rigidity than other parts, or the case body that supports the head 15, and the mounting portion 50 is mounted. This is because the stimulus applying tool B can be firmly supported. The reason why the functional head 15 is high in rigidity is that it is directly applied to the skin surface and is subjected to stress, so that its thickness is increased, or a metal material is used to improve the function. Because. Inevitably, the case body (a part of the main body case 1) that supports it also has high rigidity.

  When the rubbing body 77 is provided on the stimulus applying tool B, the function head 15 and the rubbing stimulus are applied to the skin surface by rubbing and moving while the functional head 15 and the rubbing body 77 are simultaneously applied to the skin surface. Can be given at the same time. For example, in a state in which a rubbing stimulus is applied by the rubbing body 77 while warming the skin surface with the functional head 15, physical stimulation can be applied to the skin surface while promoting blood circulation by the thermal stimulus. Further, in the state where the scrub body 77 gives a rubbing stimulus while applying cold heat to the skin surface with the functional head 15, it is possible to give a physical stimulus to the skin surface while tightening the facial skin by the cold heat stimulus.

  According to the stimulating device B composed of the connecting portion 75, the rubbing body holder 76, and the spherical rubbing body 77 rotatably supported by the holder 76, the rubbing body 77 rotates (rolls) along the skin surface. By doing so, a rubbing stimulus can be given. Therefore, the touch (feeling of touch) of the rubbing body 77 on the skin surface is soft and gentle so that a more delicate rubbing stimulus can be applied to the skin surface, and gentle massage even on delicate skin surfaces that are sensitive to external stimuli. Can do. The “at least one spherical rubbing body 77 supported rotatably” does not mean only a ball that rolls in all directions, but an axis that is rounded so that the skin contact surface is hemispherical. The body may be structured to be supported by the rubbing body holder so as to be rotatable about the axis of the shaft body. Preferably, the ball that rolls in all directions makes the touch (contact feeling) on the skin surface softer and gentler, and can give a more delicate rubbing stimulus to the skin surface. Then, a ball structure is given as a specific example.

  If the rubbing body 77 has a float structure provided between the rubbing body 77 and the connecting portion 75 and is supported so as to be floatable with respect to the main body case 1, the rubbing body 77 floats. It is possible to prevent the rubbing stimulus from acting excessively on the skin surface, and to make the touch (contact feeling) of the rubbing body 77 to the skin surface softer and gentler. In addition, since the rubbing body 77 floats following the three-dimensional skin surface change, it is possible to effectively impart rubbing stimulation by the rubbing body 77 to the skin surface.

  When the rubbing body holder 76 is supported by a float structure provided between the rubbing body holder 76 and the connecting portion 75, the structure of the structure for designing the float structure is compared with the case where only the rubbing body 77 floats. Optimization of the float structure can be promoted by expanding the degree of freedom of design such as the degree of freedom, the amount of displacement at the time of float, or the elastic deformation force accompanying the displacement.

  According to the float structure including the flexible body 90 provided between the rubbing body holder 76 and the connecting portion 75, the float structure can be simplified and the manufacturing cost of the stimulus applying tool B can be reduced. This is because the flexible body 90 also serves as at least a part of the support structure of the rubbing body holder 76, so that the support structure including the flexible body 90 is simplified and the float structure is simplified, and the stimulation is applied accordingly. This is because the component parts of the tool B can be minimized.

  In the stimulus applying tool B including the plurality of rubbing bodies 77 and the rubbing body holder 76, when one rubbing body 77 floats, if the remaining rubbing body 77 is float-moved in the opposite direction, one rubbing body 77 sinks. Since the other rubbing body 77 is lifted up by that much and the skin surface can be pressed, it is possible to appropriately impart a rubbing stimulus even on a skin surface having a large undulation.

  The float structure including a float frame 96 that surrounds the connection portion 75 and a plurality of float springs 90 that urge the float frame 96 back to the neutral position floats the float frame 96 in all directions around the connection portion 75. Can be moved. In the stimulus applying tool B having such a float structure, if a plurality of rubbing bodies 77 and rubbing body holders 76 are provided on the float frame 96, the fulcrum position when the float frame 96 tilts changes in a complex manner. Therefore, the rubbing body 77 tilting trajectory can be changed in a complicated manner. Accordingly, the movement mode of the float frame 96 is changed variously depending on the difference in how the rubbing body 77 is applied to the skin surface, and the degree of rubbing stimulus strength and the change of the part to which the rubbing stimulus is applied are diversified. A rub stimulus can be applied. Further, it is possible to appropriately impart a rubbing stimulus even on a skin surface having a large undulation.

  In the float structure in which the float frame 96 is supported by the float shaft 99 so as to be tiltable up and down, if a plurality of rubbing bodies 77 and a rubbing body holder 76 are provided on the float frame 96, the remaining rubbing when one rubbing body 77 tilts the float. The body 77 can be floated in the opposite direction. In other words, it is possible to diversify the rubbing stimulus acting on the skin surface by tilting the float frame 96 in a seesaw shape. Therefore, by selecting a state in which the rubbing stimulus is applied to the skin surface with only one rubbing body 77 and a state in which the rubbing stimulus is imparted to the skin surface with the plurality of rubbing bodies 77, the difference in skin region and the skin state are selected. Different rubbing stimuli can be applied according to the difference of the user or according to the user's preference. Further, it is possible to appropriately impart a rubbing stimulus even on a skin surface having a large undulation.

  With the thermal stimulation head 15 heated to a temperature higher than the temperature of the rubbing body 77 or with the thermal stimulation head 15 cooled to a temperature lower than the temperature of the rubbing body 77, the thermal stimulation head 15 and the rubbing body 77 are placed on the skin surface. When the thermal stimulation and rubbing stimulation are simultaneously applied to the skin surface by acting simultaneously, physical stimulation can be applied while promoting blood circulation on the skin surface, or physical stimulation can be applied while tightening the skin surface.

  If the rubbing body 77 is elastically supported by the float spring 90 provided in the rubbing body holder 76, the rubbing body 77 can be elastically supported by a weak spring force, and thus the touch (feeling of contact) of the rubbing body 77 with respect to the skin surface can be achieved. It can also be soft and gentle.

  When the functional head 15 and the rubbing body 77 are simultaneously applied to the skin surface, the functional head 15 gives a strong rubbing stimulus and the rubbing body 77 gives a weak rubbing stimulus. By properly using the functional head 15 and the rubbing body 77 according to the difference, rubbing stimulation according to the user's preference can be given to the skin surface.

  When the first virtual plane H1 passing through the top of the rubbing body 77 is positioned above the head virtual plane H passing through the top of the functional head 15, the first virtual plane H1 and the head virtual plane H are flush with each other. Only in the state, the action by the functional head 15 and the rubbing stimulus by the rubbing body 77 can be simultaneously applied to the skin surface. At this time, since the spring force of the float spring 90 acts on the rubbing body 77, the rubbing body 77 is securely adhered to the skin surface, and the rubbing stimulus when the rubbing body 77 rolls is applied to the skin surface. it can.

  In the float position, if the second virtual plane H2 passing through the top of the rubbing body 77 is positioned at or below the head virtual plane H passing through the top of the functional head 15, the rubbing body 77 is placed on the skin surface. It can be prevented from being excessively pressed, and the touch to the skin surface of the rubbing body 77 can be made soft and gentle so that a more delicate rubbing stimulus can be applied to the skin surface.

  When the area of the skin contact surface 25 of the functional head 15 is set to be larger than the area of one rubbing body 77 in plan view, the function of the functional head 15 is allowed to act on the skin surface with the skin contact surface 25 having a large area. However, the rubbing body 77 with a small area can rub the skin surface. According to such a small electric appliance, the function of the functional head 15 can be applied mainly to the skin surface. The rubbing stimulation by the rubbing body 77 is incidental.

  When a plurality of rubbing bodies 77 composed of spheres (balls) are rotatably supported by a rubbing body holder 76, the touch (feeling of contact) of the rubbing body 77 with respect to the skin surface is soft and gentle, and more delicate rubbing stimulation Can be applied to the skin surface, and even gentle skin surfaces sensitive to external stimuli can be gently massaged.

  Although the area of one rubbing body 77 in plan view is smaller than the area of the skin contact surface 25 of the functional head 15, the total area of the plurality of rubbing bodies 77 in plan view is the area of the skin contact surface 25 of the functional head 15. If it is set larger, when the action of the functional head 15 and the rubbing stimulus are simultaneously applied to the skin surface, the rubbing stimulus can be given mainly to the skin surface. At the same time, the function of the function head 15 can be applied.

  When comparing the curvature of the skin contact surface 25 of the functional head 15 formed in an upwardly curved shape with the curvature of the rubbing body 77 made of a sphere, the former curvature is set smaller than the latter curvature, and the latter curvature is set larger than the former curvature. Then, the contact opportunity between the skin contact surface 25 and the skin surface can be increased more than the contact opportunity between the rubbing body 77 and the skin surface, and the action of the skin contact surface 25 can be accurately given to the skin surface.

  If the rubbing body 77 is integrated with the rubbing body holder 76 and elastically supported by a plurality of receiving arms 87 provided on the bottom of the rubbing body holder 76, a support structure can be configured at low cost.

  When the rubbing body 77 is received by a plurality of receiving arms 87 provided on the bottom of the rubbing body holder 76 and the peripheral surface on the bottom surface side of the rubbing body 77 is exposed to the bottom surface side of the rubbing body holder 76, the stimulus applying device The discharge of the cleaning liquid when cleaning B can be facilitated. Further, since cleaning can be performed while pouring cleaning water from the upper peripheral surface of the rubbing body 77 or the bottom surface side of the rubbing body holder 76 at the time of cleaning, the entire surface of the rubbing body 77 can be surely cleaned.

  In a state where the connecting portion 75 of the stimulus applying tool B is mounted on the mounting portion 50, if a water passing space S is secured between the bottom surface of the rubbing body holder 76 and the main body case 1, the rubbing body 77 and the rubbing body holder The washing water that has flowed down from 76 can be reliably drained from the water flow space S. Further, it is possible to improve the ventilation of the rubbing body 77 and the rubbing body holder 76 after the cleaning, thereby promoting drying.

  When the connecting portion 75 of the stimulus applying tool B is composed of a plurality of connecting legs 79 and a water passage opening is provided between the connecting legs 79 adjacent in the circumferential direction, cleaning is performed along the connecting legs 79 and the mounting portion 50. It is possible to prevent the cleaning water from staying around the connecting leg 79 and the mounting portion 50 by causing the water to flow down quickly.

  When the impregnating body C that covers the outer surface of the skin electrode 65 is pressed and fixed with the stimulus applying tool B mounted on the mounting portion 50, there is no need to separately prepare a fixing tool for fixing the impregnating body C, The configuration can be simplified. Therefore, the periphery of the skin electrode 65 can be made compact, and usability can be improved.

The heat radiating fin 28 protrudes greatly downward from the sink block 27 with its lower end entering the inside of the front and rear cases 10 and 11, and the total surface area is increased to increase the heat conducted to the sink block 27. Or cold heat can be radiated effectively. The fastening seat 29 is formed with a screw insertion hole 33 having a vertically penetrating shape, and an engagement recess 34 having a tunnel cross-sectional shape is formed in the upper end thereof. The plan view shape of the heat transfer section 30 is made to coincide with the cross-sectional shape of the head shaft 21, and the plan view shape of the heat receiving table 31 is formed in a rectangular shape slightly larger than the outer shape of the Peltier element 17.

  The Peltier element 17 is a commercially available heat generating module having a thin rectangular parallelepiped shape, and a heat transfer sheet 35 made of silicone resin is disposed on the upper and lower surfaces thereof. By supplying a DC driving current to the Peltier element 17, for example, the element upper surface side can generate heat and heat can be absorbed from the element lower surface, and by reversing the polarity of the driving current, the element lower surface side can generate heat and the element Heat absorption can be performed from the upper surface. Such a difference in operation mode can be switched by turning on the power button 4 and then turning on the heat switching button 5 once or turning it on twice.

  The spacer 18 is formed of a square frame-shaped plastic molded product surrounding the periphery of the Peltier element 17, and a vertically long positioning rib 38 is integrally provided at the center of the front surface thereof. As shown in FIGS. 1 and 8, when the heat generating unit 2 is assembled to the head case 9, the periphery of the Peltier element 17 is covered with a spacer 18 in a sealed manner. Therefore, for example, when the operation of the Peltier element 17 is stopped from the state in which the thermal stimulation head 15 is heated by the Peltier element 17, the Peltier element 17 may be overheated by feedback heat conducted from the thermal stimulation head 15 having a large heat capacity. is there. In order to quickly release such feedback heat, groove-shaped exhaust heat openings 39 for heat release are formed at a total of four corners of the square frame spacer 18. The groove formed in the front wall of the spacer 18 is a groove for passing the power supply lead led out from the Peltier element 17, and this groove also exerts a heat release function like the exhaust heat opening 39. Further, protrusions 40 are provided on the peripheral wall excluding the front wall of the spacer 18 and the upper surface of the positioning rib 38 to prevent the upper surfaces of the spacer 18 and the positioning rib 38 from coming into close contact with the lower surface of the thermal stimulation head 15. Is prevented from conducting to the spacer 18 side. In order to effectively perform such heat insulation, the spacer 18 is preferably formed of a plastic material that is difficult to conduct heat.

  The head case 9 has a terrace-like shape including an upper head cylinder wall 42 having a cross-sectional shape similar to that of the head shaft 21 and a lower round cylindrical connection cylinder wall 43 that is slightly larger than the upper cylinder wall 42. Made of plastic molding. In order to assemble the heat generating unit 2 into the head case 9 with a simpler structure, an assembly seat 44 for receiving the overhanging wall 22 of the thermal stimulation head 15 is formed at the upper end of the head cylinder wall 42, and the center of the assembly seat 44 is formed. A head opening 45 is formed in the head. Screw bosses 46 for fastening the sink block 27 are integrally formed on the left and right sides of the inner surface of the connecting cylinder wall 43. As shown in FIG. 9, vertical ribs 47 for absorbing dimensional errors are formed at five locations around the screw boss 46. A shoulder 48 is formed between the head cylinder wall 42 and the connection cylinder wall 43, and a connection groove 49 is formed at the lower end of the connection cylinder wall 43 so as to be held between the front and rear cases 10 and 11. In the state where the heat generating unit 2 is assembled to the head case 9, since the previous vertical rib 47 contacts the engaging recess 34, the peripheral surface of the screw boss 46 is in close contact with the inner peripheral surface of the engaging recess 34. Absent. In this embodiment, the head tube wall 42 also serves as the mounting portion 50 for attaching and detaching a stimulus applying tool B described later.

  As described above, the thermistor 51 is disposed in the hole 24 inside the thermal stimulation head 15. In this embodiment, an NTC thermistor whose resistance value decreases as the temperature rises is used as the thermistor 51, and the thermistor 51 is held by the sensor holder 52 fitted in the hole 24 (see FIG. 7). As shown in FIG. 4, the sensor holder 52 formed of silicone resin has a lower end in close contact with the Peltier element 17 via the heat transfer sheet 35, and a peripheral surface thereof is in close contact with the inner surface of the hole 24. The Peltier element 17 and the thermal stimulation head 15 function as a heat conductor that transfers heat to the thermistor 51.

  The front case 10 and the rear case 11 that constitute the gripping case 8 are each composed of a half case that is divided into the front and rear that constitute the grip portion of the main body case 1, and are engaged with the connecting groove 49 of the head case 9 at the upper ends of the two cases. A semicircular connecting rib 54 is formed. In addition, case screw bosses 55 for fastening the rear case 11 are formed at four positions on the inner surface of the front case 10, and four pieces corresponding to the case screw bosses 55 are formed on the upper and lower sides of the case wall of the rear case 11. The screw insertion hole 56 is formed. On the inner surface of the front case 10, a control board 13 and a socket 57 for connecting a power supply plug led out from the charger are assembled. Reference numeral 58 denotes a connection pin provided in the socket 57.

  As shown in FIG. 1, among the four case screw bosses 55, a pair of upper and left case screw bosses 55 are mounted in a state in which a tilt regulating body 60 that regulates the tilt of the heat sink 16 is fitted. . The tilt restricting body 60 is formed of a rubber, silicone resin, elastically deformable porous resin or the like in the shape of a tunnel cross section, and a mounting hole 61 that fits around the case screw boss 55 near the center. Is provided. Further, a flat fin receiving surface 62 is provided on the peripheral surface of the tilt restricting body 60 that faces the heat radiation fin 28 of the heat sink 16.

  An electrical stimulation structure is provided to perform a cosmetic process for ion derivation and ion introduction. In FIG. 11, the electrical stimulation structure is weak to the first electrode (skin electrode) 65 that contacts the skin surface, the second electrode (grip electrode) 66 provided at the rear part of the main body case 1, and these electrodes 65 and 66. A control circuit for supplying a pulse current is used. In this embodiment, the first electrode 65 is formed by using the thermal stimulation head 15. That is, the thermal stimulation head 15 also serves as the first electrode 65. A control circuit (not shown) is mounted on the control board 13 and supplies a pulse current with one of the first electrode 65 and the second electrode 66 having a positive polarity and the other having a negative polarity. The second electrode 66 is formed by pressing a titanium plate into a curved shape that is easy to grip. Here, the electrical stimulation is a concept that includes electrical muscle stimulation that is set higher than the voltage at the time of ion introduction and ion derivation, in addition to ion introduction and ion derivation. In the case of this electrical muscle stimulation, a small electric appliance is used as a treatment device.

  The heat generating unit 2 is assembled to the head case 9 in the following manner. When assembling, the thermistor 51 and the sensor holder 52 are mounted on the head shaft 21 in advance, and the O-ring 68 is mounted on the base end portion of the head shaft 21. As shown in FIG. 6, the Peltier element 17 is assembled with the heat transfer sheet 35 on the upper surface of the heat receiving table of the sink block 27, and the spacer 18 is assembled to the sink block 27. Next, the thermal stimulation head 15 is inserted into the head opening 45 from the inner surface side of the head case 9 so that the skin contact surface 25 protrudes above the head case 9. Further, the Peltier element 17 and the spacer 18 are assembled together with the heat sink 16, the spacer 18 is attached to the heat transfer portion 23 of the thermal stimulation head 15, and the fastening seat 29 of the sink block 27 is joined to the screw boss 46 of the head case 9. Then, the screw boss 46 and the engaging recess 34 are engaged. In this state, the heat generating unit 2 can be integrated with the head case 9 by screwing two screws (sink fastening screws) 69 into the screw boss 46 as shown in FIG.

  As described above, when the body case 1 and the heat sink 16 are used to fix and hold the thermal stimulation head 15, the thermoelectric conversion element 17, and the spacer 18, the heat sink 16 is simply fastened to the body case 1 with the screw 69. The persons 15, 17 and 18 can be firmly fixed at the same time. Accordingly, all of the components of the heat generating structure can be securely fastened and fixed with a simpler structure, and the assembling work can be saved accordingly.

  In addition, since the heat generating structure is configured by the heat stimulation head 15, the heat sink 16, the thermoelectric conversion element 17, and the spacer 18 which are indispensable for applying the heat stimulation, unnecessary parts are omitted as compared with conventional beauty instruments. Thus, the structure of the heat generating structure can be simplified and made compact, and accordingly, the beauty device including the heat generating structure can be made smaller and more compact. Furthermore, since the heat conducted from the thermoelectric conversion element 17 to the heat sink 16 can be conducted to the main body case 1 via the screws 69 and radiated on the surface of the main body case 1, the heat radiation effect by the heat sink 16 can be improved.

  Further, the engagement recess 34 provided in the fastening seat 29 of the sink block 27 is engaged with the screw boss 46 of the head case 9 so that the screw 69 is screwed into the screw boss 46 in a state where the heat sink 16 is positioned in the front, rear, left and right directions. The fastening of the heat sink 16 to the screw boss 46 can be performed accurately and firmly. Further, in a state where the engaging recess 34 is engaged with the screw boss 46, the protrusions of the vertical ribs 47 abut against the engaging recess 34 to absorb the dimensional variation, so that the heat sink 16 is always properly attached to the head case 9. Can be fixed to.

  The thermal stimulation head 15 fixed to the head case 9 is pressed by the spacer 18 and the heat sink 16, and the overhanging wall 22 is pressed against the assembly seat 44 via the O-ring 68. Is received by the inner surface of the head tube wall 42. Further, the Peltier element 17 is sandwiched and fixed between the heat receiving table 31 of the heat sink 16 and the heat transfer section 23 of the thermal stimulation head 15. That is, the thermal stimulation head 15 and the Peltier element 17 are fixed and held by the heat sink 16 and the spacer 18 fastened to the head case 9 and the same case. Finally, the connecting ribs 54 of the front case 10 and the rear case 11 to which the secondary battery 12 and the control board 13 are assembled are engaged with the connecting grooves 49 of the head case 9, and as shown in FIG. The assembly of the main body A can be completed by screwing a screw (case fastening screw) 70 into the case screw boss 55. In this state, both side surfaces of the heat radiation fin 28 of the heat sink 16 are received by the fin receiving surfaces 62 of the tilt regulating body 60. Therefore, when the radiating fin 28 is thermally expanded or thermally contracted, the deformation of the radiating fin 28 can be absorbed by the tilt regulating body 60 being compressed or expanded.

  12 to 14, the stimulus applying tool B includes a connecting portion 75 that is attached to and detached from the mounting portion 50 (head cylinder wall 42) of the head case 9, and a ball holder that is integrally provided at three locations around the upper portion of the connecting portion 75. A (rubbing body holder) 76 and a plastic ball (rubbing body) 77 rotatably supported by the ball holder 76 are provided. The connecting portion 75 is integrally provided with a connecting end wall 78 at the upper end and three connecting legs 79 protruding downward from the periphery of the connecting end wall 78, and the head shaft 21 is provided at the center of the connecting end wall 78. A shaft passage 80 for passing through is formed. Since there is an opening between the connecting legs 79 adjacent in the circumferential direction, the stimulus applying tool B can be reduced in weight by the amount of the opening. In a state in which the stimulus imparting tool B is mounted on the head cylinder wall 42, each connecting leg 79 engages with a cylindrical wall portion where the top of the head cylinder wall 42 is rounded in an elastically deformed state. The connecting portion 75 and the ball holder (rubbing body holder) 76 are made of plastic in this embodiment, but may be made of metal.

  The ball holder 76 is formed by two holding cylinder walls 82 having a long circumference divided by a slit 81 and two holding cylinder walls 83 having a short circumference, and the inner surfaces of these holding cylinder walls 82 and 83. Three pairs of retaining claws 84 are formed at the upper end of each. As shown in FIG. 13, the retaining claw 84 is formed facing the slit 81. The diameter of the imaginary circle passing through the inner surfaces of the holding cylinder walls 82 and 83 is slightly larger than the sphere diameter of the ball 77, and the diameter of the imaginary circle passing through the claw end of the retaining claw 84 is slightly smaller than the sphere diameter of the ball 77. It is set. Thereby, the ball 77 in use can give a rubbing stimulus while rotating along the skin surface. Note that the ball 77 can be mounted inside the ball holder 76 by pushing in the holding cylindrical walls 82 and 83 while being elastically deformed in an expanded shape.

  The stimulus imparting tool B also serves as a fixing tool for fixing and holding the sheet-like impregnated body C that covers the surface of the skin contact surface 25, and the lower end of the total of six short holding cylinder walls 83 and the connecting portion. The peripheral edge of the impregnated body C is clamped and fixed in cooperation with the head cylinder wall 42 and the head shaft 21 of the head case 9 by a part of the connection end wall 78 of 75 (see FIG. 14). The impregnation body C may be fixedly held only by the ball holder 76 or by the connecting portion 75 alone. In short, it is only necessary that the impregnated body C can be fixed by the stimulus applying tool B. As described above, by supporting the ball 77 with the three pairs of retaining claws 84, the lower peripheral surface of the ball 77 is exposed on the lower surface side of the ball holder 76. Therefore, the surface of the ball 77 can be thoroughly cleaned when the stimulus applying tool B is cleaned. The impregnated body C is formed by forming cloth, cotton (absorbent cotton), sponge, nonwoven fabric or the like into a sheet. As described above, when the impregnated body C covering the outer surface of the skin electrode 65 is pressed and fixed by the connecting portion 75 or / and the rubbing body holder 76 of the stimulus applying tool B mounted on the mounting portion 50, the impregnated body C is fixed. It is not necessary to prepare a fixing tool to be prepared separately, and the configuration around the skin electrode 65 can be simplified. Therefore, the periphery of the skin electrode 65 can be made compact, and usability can be improved. In this embodiment, the impregnation body C is sandwiched and fixed by the stimulus applying tool B, the head case 9 and the thermal stimulation head 15, but the impregnation body C can be sandwiched and fixed only by the stimulus applying tool B and the head case 9. Alternatively, the impregnated body C can be clamped and fixed only by the stimulus applying tool B and the thermal stimulation head 15. In short, the impregnated body C only needs to be sandwiched and fixed between the stimulus applying tool B and the main body A.

  In order to support the ball 77 with respect to the main body case 1 so that it can float up and down, a float structure is provided. The float structure includes three elastically deformable receiving arms 87 that are integrally provided on the bottom of each ball holder 76. The receiving arm 87 is continuous with the lower end wall of the previous slit 81 and is extended obliquely downward toward the center of the ball holder 76, and obliquely directed from the lower end of the arm base 88 toward the center of the ball holder 76. The ball 77 is elastically supported by receiving the lower peripheral surface of the ball 77 attached to the ball holder 76 at the tip of the support arm 89. Since both the arm base 88 and the support arm 89 extend in an oblique direction to increase the overall length of the receiving arm 87, plastic deformation is unlikely to occur, and elastic force (spring force) can be maintained even when subjected to a large pressing force. . Thus, by elastically supporting the lower peripheral surface of the ball 77 with the free ends of the three receiving arms 87 that can be elastically deformed, the ball 77 can be rolled in all directions, and the ball 77 and the receiving arm By making point contact with 87, rolling resistance can be reduced, and the ball 77 can be smoothly rotated on the skin surface. Therefore, the receiving arm 87 in this embodiment also serves as a float spring (flexible body) 90 that pushes up and biases the ball 77. During use, the ball 77 can float up and down between a standby position pushed up by the receiving arm 87 and a float position pushed down against the urging force of the receiving arm 87. When any of the three balls 77 receives the skin reaction force, the ball 77 sinks to the bottom surface side of the ball holder 76 against the spring force of the float spring 90 and touches the skin surface of the rubbing body 77 (contact feeling). Can be soft and gentle. As shown in FIG. 14, the balls 77 supported in the ball holders 76 are all at the same height in a direction orthogonal to the skin contact surface 25 or in the same direction as the axial direction of the thermal stimulation head 15. Regarding the material of the receiving arm 87, since each ball holder 76 is made of plastic, the receiving arm 87 integrated therewith is also made of plastic. The ball holder 76 and the receiving arm 87 may be made of metal such as stainless steel.

  FIG. 14 shows a state in which the stimulus applying tool B is mounted on the head cylinder wall 42. The first virtual plane H1 passing through the top of the ball 77 in this state is positioned above the head virtual plane H passing through the top of the thermal stimulation head 15, that is, the top of the skin contact surface 25. In addition, at the float position where the ball 77 receives the skin reaction force and sinks to the maximum extent into the ball holder 76 while elastically deforming the receiving arm 87, the second virtual plane H2 passing through the top of the ball 77 is skin contact. It is located below the head virtual plane H passing through the top of the surface 25. A water passage space S is secured between the ball holder 76 and the shoulder portion 48 of the head case 9, and the provision of the space S facilitates the discharge of cleaning water. Further, in the state where the stimulus applying tool B is mounted on the head cylinder wall 42, as shown by the phantom line (two-dot chain line) in FIG. The balls 77 are arranged adjacent to each other. The balls 77 are arranged so that the circumferential distances are equal. Further, the balls 77 are arranged so that the radial distances are equal. As described above, when the ball 77 that rolls in all directions is provided adjacent to the thermal stimulation head 15, when the functional head 15 is moved in contact with the skin, the movement resistance is reduced, and thus the user is reduced. Can move the thermal stimulation head 15 with a weak force. Furthermore, if the first virtual plane H1 passing through the top of the ball 77 is positioned above the head virtual plane H passing through the top of the thermal stimulation head 15, the movement becomes even easier. In particular, if a plurality of balls 77 are arranged around the thermal stimulation head 15 at the same height in the circumferential direction, movement in all directions is further facilitated, and the thermal stimulation head 15 is inappropriate for the skin surface. It is possible to make contact without any significant tilting. More preferably, a plurality of rolling balls 77 are evenly arranged in the circumferential direction around the thermal stimulation head 15. That is, a rollable ball 77 is provided adjacent to the functional head 15, and three balls 77 are provided so as to surround the functional head 15. Each ball 77 is arranged so as to form an equilateral triangle when the balls 77 are connected by a straight line. Specifically, the balls 77 are arranged so as to form an equilateral triangle when the balls 77 are connected in a straight line as viewed in a plan view, that is, from the side facing the skin contact surface 25 of the functional head 15. Further, since the rolling ball 77 is elastically supported and floatable, an excessive load is not imposed on the skin surface. Even if the head virtual plane H is below the first virtual plane H 1 passing through the top of the ball 77 and the ball 77 does not float with respect to the ball holder 76, the skin pressed by the ball 77 Since the surface is concave and the ball 77 sinks against the skin surface, the skin contact surface 25 of the thermal stimulation head 15 can easily contact the skin surface.

  The relationship between the skin contact surface 25 and the ball 77 is set as follows. The area of the skin contact surface 25 is set larger than the area of one ball 77 in plan view, but the total area of the three balls 77 in plan view is set larger than the area of the skin contact surface 25. is there. Whereas the curvature of the skin contact surface 215 formed in an upwardly curved shape is set small, the curvature of the ball 77 is set large. According to such a stimulus applying tool B, a strong rubbing stimulus can be given to the skin surface with the thermal stimulation head 15, and a local weak rubbing stimulus can be given to the skin surface with the ball 77.

  The beauty device configured as described above is configured by simultaneously rubbing the face skin (skin surface) with the skin contact surface 25 of the head shaft 21 and the ball 77 in a state where the stimulus imparting tool B is mounted on the head cylinder wall 42. A physical stimulus can be applied to the surface. An ion introduction mode or an ion derivation mode in which a weak pulse current is supplied to the first electrode 65 and the second electrode 66 in a state where the impregnated body C impregnated with a cosmetic liquid is attached to the surface of the skin contact surface 25 With this, electrical stimulation can be applied to the skin surface. Further, the heat or cold generated by the Peltier element 17 can be conducted to the thermal stimulation head 15, and the skin surface can be stimulated in the thermal stimulation mode in which thermal stimulation is applied to the skin surface or in the cold stimulation mode. Since the stimulus imparting device B is detachably attached to the main body portion A, when no rubbing stimulus is required, the stimulus imparting device B is removed from the main body portion A and separated, thereby separating the heat stimulus head (function The head 15 can be used alone. This facilitates partial care of the skin.

  In the ion introduction mode, the power button 4 is turned on and then the ion switching button 6 is turned on, so that the left indicator lamp 6a is turned on toward FIG. A voltage with the second electrode 66 having a positive polarity is applied to both electrodes 65 and 66 from the control circuit. In this state, the gripping case 8 including the second electrode 66 is gripped, and the first electrode 65 is applied to the skin surface to be cared for through the impregnated body C impregnated with the cosmetic liquid. Can be supplied, and the moisturizing component of the cosmetic liquid can penetrate into the skin. Also, by impregnating the impregnated body C and the ball 77 against the skin surface and rubbing it, ion introduction is performed and the moisturizing component of the cosmetic liquid is infiltrated into the skin, and a gentle rubbing stimulus by the ball 77 is given to exert a massage effect. it can. In the case where the cosmetic liquid is applied to the skin surface in advance, the impregnated body C can be omitted and the first electrode 65 can be directly brought into contact with the skin surface for ion introduction.

  In the ion derivation mode, the power button 4 is turned on, and then the ion switching button 6 is turned on twice. As a result, the right indicator lamp 6b is turned on as shown in FIG. A voltage having the polarity and the second electrode 66 having a negative polarity is applied to both electrodes 65 and 66 from the control circuit. In this state, the gripping case 8 including the second electrode 66 is gripped, and the first electrode 65 is applied to the skin surface to be cared for through the impregnated body C impregnated with the cosmetic liquid. And fine dirt on the skin can be adhered to the impregnated body C. Further, by impregnating the impregnated body C and the ball 77 against the skin surface and rubbing, gentle rubbing stimulation by the ball 77 can be given while performing ion derivation to remove fine dirt on the skin surface. At this time, it is possible to extend the facial skin while applying gentle rubbing stimulation by the ball 77 to promote the discharge of fine dirt. Further, the massage effect can be exhibited by the rubbing stimulation of the ball 77.

  In the thermal stimulation mode, the power button 4 is turned on, and then the heat switching button 5 is turned on, so that the left indicator lamp 5a is turned on toward FIG. 2, and the thermal generated by the Peltier device 17 is heated. Conducted to the head 15. At this time, the cold generated by the Peltier element 17 is conducted to the sink block 27 and radiated from the radiation fins 28. In this way, with the thermal stimulation head 15 heated to a temperature higher than the temperature of the ball 77, the skin contact surface 25 of the thermal stimulation head 15 and the ball 77 are simultaneously applied to the skin surface and rubbed, thereby thermally stimulating the skin surface. And rub stimulation can be applied simultaneously to promote blood circulation. In the thermal stimulation mode, a strong rubbing stimulus is applied to the skin contact surface 25 of the thermal stimulation head 15 and a weak rubbing stimulus is applied to the ball 77. In addition, the contraction deformation of the radiation fin 28 at the time of radiating cold heat is absorbed by the tilt regulating body 60 being expanded and deformed.

  In the thermal stimulation mode, the power button 4 is turned on, and then the heat switching button 5 is turned on twice. As a result, the right indicator lamp 5b is turned on as shown in FIG. Conducted to the thermal stimulation head 15. Further, the heat generated by the Peltier element 17 is conducted to the sink block 27 and is radiated from the radiation fins 28. In this way, with the thermal stimulation head 15 cooled to a temperature lower than the temperature of the ball 77, the skin contact surface 25 of the thermal stimulation head 15 and the ball 77 are simultaneously applied to the skin surface and rubbed to thereby cool the skin surface. The skin surface can be tightened by simultaneously applying rubbing stimulation. In the cool heat stimulation mode, a strong rubbing stimulus is applied to the skin contact surface 25 of the heat stimulating head 15, and a weak rubbing stimulus is applied to the ball 77. In addition, the expansion deformation of the radiation fin 28 when the heat is radiated is absorbed by the tilt regulating body 60 being contracted and deformed.

  In each of the stimulation modes described above, it is possible to prevent the ball 77 from floating up and down between the standby position and the float position, and the rubbing stimulation by the ball 77 from acting excessively on the skin surface. Therefore, the touch (contact feeling) on the skin surface of the ball 77 can be made softer and gentler than a beauty instrument that does not have a float structure. Further, since the ball 77 floats up and down following the three-dimensional skin surface change, it is possible to effectively impart the rubbing stimulus by the ball 77 to the skin surface. Further, since the heat generated by the thermoelectric conversion element 17 as well as the cold generated by the thermoelectric conversion element 17 can be applied to the skin surface by the thermal stimulation head 15, the thermal stimulation on the skin surface can be diversified to improve the beauty effect. The ion derivation mode, the ion introduction mode, the thermal stimulation mode, and the thermal stimulation mode can be operated independently, but can be simultaneously driven in a state where the combination is changed. Specifically, when the power button 4 is in the on state, pressing the ion switching button 6 once enters the ion introduction mode, pressing the ion switching button 6 twice enters the ion derivation mode, and pressing the ion switching button 6 three times. Current supply to the electrodes 65 and 66 is turned off. When the power button 4 is in the on state, pressing the heat switching button 5 once enters the thermal stimulation mode, pressing the heat switching button 5 twice enters the cold stimulation mode, and pressing the heat switching button 5 three times causes Peltier. The current supply to the element 17 is turned off. As described above, each mode of the ion derivation mode, the ion introduction mode, the thermal stimulation mode, and the cold stimulation mode can be operated independently. In addition, in the ion introduction mode, either the thermal stimulation mode or the cold stimulation mode can be operated simultaneously. Similarly, in the ion derivation mode, either the thermal stimulation mode or the cold stimulation mode can be operated simultaneously. it can. In this way, the beauty tool can be switched to eight types of operation patterns.

  In this embodiment, the functional head 15 is a multi-functional type that is a thermal stimulation head 15 that can apply thermal stimulation or cold stimulation to the skin surface and an electrode head 15 (skin electrode 65) that can apply electrical stimulation to the skin surface. However, it may be a multifunctional functional head 15 in which a vibrator or a piezoelectric element is provided in the head and a function capable of imparting sonic vibration or ultrasonic vibration to the skin surface is added. Conversely, a functional head 15 having a simple structure in which the above-described functions are mounted as a single function may be used.

  In the beauty device having the above-described configuration, the stimulus imparting tool B that imparts a rubbing stimulus to the skin surface is provided in the mounting portion 50, whereby a rubbing stimulus can be imparted to the skin surface separately from the action of the functional head 15. The phrase “stimulation applicator B is provided in the mounting portion 50” includes a configuration in which the stimulus applicator B is fixed to the mounting portion 50 in an inseparable manner. For example, the functional head 15 or the head 15 is If the supporting body (a part of the main body case 1 such as the head case 9 and the gripping case 8) is used as the mounting portion 50 and the stimulus applying tool B is detachably mounted thereto, the stimulus applying tool B is attached to the main body case 1. Can be connected in a stable state. This is because the structural strength of the mounting part 50 is strengthened by attaching the mounting part 50 to the heat stimulation head 15 having a higher rigidity than the other parts, or the case body that supports the head 15, and the mounting part 50 is attached to the same. This is because the stimulated applicator B can be firmly supported. The reason why the functional head 15 is high in rigidity is that it is directly applied to the skin surface and is subjected to stress, so that its thickness is increased, or a metal material is used to improve the function. Because. Inevitably, the case body (a part of the main body case 1) that supports it also has high rigidity. Further, the above-mentioned “configuration in which the functional head 15 or the case body supporting the head 15 is used as the mounting portion 50 and the stimulus applicator B is detachably mounted” is the complete example of the stimulus applicator B as in this embodiment. A part of the stimulus applicator B is attached to the main body case 1 via a hinge, and the use form adjacent to the functional head 15 and the stimulus applicator B are rotated from the use form. The state may be changed between a non-use form located at a position separated from the functional head 15. The latter attachment / detachment structure can surely prevent the stimulus applying tool B from being lost.

  Further, when the stimulus applying tool B is provided with the rubbing body 77, the function head 15 and the rubbing body 77 can be rubbed and moved while simultaneously acting on the skin surface. A rubbing stimulus can be applied simultaneously. For example, in a state in which a rubbing stimulus is applied by the rubbing body 77 while warming the skin surface with the thermal stimulation head 15, physical stimulation can be applied to the skin surface while promoting blood circulation by the thermal stimulation. Further, in a state in which the thermal stimulation head 15 applies a cold stimulus to the skin surface while applying a thermal stimulus to the skin surface, a physical stimulus can be applied to the skin surface while the facial skin is tightened by the cold thermal stimulus.

  Further, according to the stimulus applying tool B configured by the connecting portion 75, the rubbing body holder 76, and the spherical rubbing body 77 rotatably supported by the holder 76, the rubbing body 77 rotates along the skin surface. It can give a rubbing stimulus. Therefore, the touch (feeling of touch) of the rubbing body 77 on the skin surface is soft and gentle so that a more delicate rubbing stimulus can be applied to the skin surface, and gentle massage even on delicate skin surfaces that are sensitive to external stimuli. Can do.

  Further, the thermal stimulation head 15 and the rubbing body 77 are skinned in a state where the thermal stimulation head 15 is heated to a temperature higher than the temperature of the rubbing body 77 or in a state where the thermal stimulation head 15 is cooled to a temperature lower than the temperature of the rubbing body 77. Applying thermal stimulation and rubbing stimulation to the skin surface at the same time can apply physical stimulation while promoting blood circulation on the skin surface, or can apply physical stimulation while tightening the skin surface. .

  Further, when the rubbing body 77 is elastically supported so as to be floatable by a float spring 90 provided in the rubbing body holder 76, the rubbing body 77 can be elastically supported by a weak spring force, so that the rubbing body 77 touches the skin surface. (Contact feeling) can be further soft and gentle.

  In addition, when the functional head 15 and the rubbing body 77 are simultaneously applied to the skin surface, when the functional head 15 imparts a strong rubbing stimulus and the rubbing body 77 imparts a weak rubbing stimulus, the difference in the skin surface area and the skin By properly using the functional head 15 and the rubbing body 77 according to the difference in state, it is possible to impart a rubbing stimulus according to the user's preference to the skin surface.

  When the first virtual plane H1 passing through the top of the rubbing body 77 is positioned above the head virtual plane H passing through the top of the functional head 15, the first virtual plane H1 and the head virtual plane H are flush with each other. Only in this state, the action by the functional head 15 and the rubbing stimulus by the rubbing body 77 can be simultaneously applied to the skin surface. At this time, since the spring force of the float spring 90 acts on the rubbing body 77, the rubbing body 77 is securely adhered to the skin surface, and the rubbing stimulus when the rubbing body 77 rolls is applied to the skin surface. it can. If the ball 77 that rolls in all directions is provided adjacent to the functional head 15, as another effect, the user moves along the skin surface while the functional head 15 is in contact with the skin. Becomes easy.

  In addition, when the second virtual plane H2 passing through the top of the rubbing body 77 is positioned at the same level as or below the head virtual plane H passing through the top of the functional head 15 at the float position, the rubbing body 77 is By preventing excessive pressing on the surface, the touch of the rubbing body 77 against the skin surface can be made soft and gentle, and a more delicate rubbing stimulus can be applied to the skin surface.

  Further, when the area of the skin contact surface 25 of the functional head 15 is set to be larger than the area of one rubbing body 77 in plan view, the function of the functional head 15 can be applied to the skin surface with the skin contact surface 25 having a large area. While acting, rubbing stimulation can be given to the skin surface with the rubbing body 77 having a small area. According to such a beauty tool, the function of the functional head 15 can be made to act mainly on the skin surface. The rubbing stimulation by the rubbing body 77 is incidental.

  Further, when a plurality of rubbing bodies 77 made of a sphere are rotatably supported by the rubbing body holder 76, the touch (feeling of contact) on the skin surface of the rubbing body 77 is soft and gentle, and more delicate rubbing stimulation is provided. It can be applied to the skin and can be gently massaged even on delicate skin that is sensitive to external stimuli.

  The area of one rubbing body 77 in plan view is smaller than the area of the skin contact surface 25 of the functional head 15, but the total area of the plurality of rubbing bodies 77 in plan view is the skin contact surface 25 of the functional head 15. If the area is set to be larger than the area, when the action of the functional head 15 and the rubbing stimulus are simultaneously applied to the skin surface, the rubbing stimulus can be mainly given to the skin surface. At the same time, the function of the function head 15 can be applied.

  Further, when comparing the curvature of the skin contact surface 25 of the functional head 15 formed in an upwardly curved shape and the curvature of the rubbing body 77 made of a sphere, the former curvature is set smaller than the latter curvature, and the latter curvature is smaller than the former curvature. If it is set to be large, the contact opportunity between the skin contact surface 25 and the skin surface is made larger than the contact opportunity between the rubbing body 77 and the skin surface, and the action of the skin contact surface 25 can be accurately given to the skin surface.

  Further, when the rubbing body 77 is elastically supported by the plurality of receiving arms 87 provided integrally with the rubbing body holder 76 and provided on the bottom of the rubbing body holder 76, a support structure can be configured at low cost.

  Further, when the rubbing body 77 is received by the plurality of receiving arms 87 provided on the bottom of the rubbing body holder 76 and the peripheral surface on the bottom surface side of the rubbing body 77 is exposed to the bottom surface side of the rubbing body holder 76, The discharge of the cleaning liquid when cleaning the applicator B can be facilitated. Further, since cleaning can be performed while pouring cleaning water from the upper peripheral surface of the rubbing body 77 or the bottom surface side of the rubbing body holder 76 at the time of cleaning, the entire surface of the rubbing body 77 can be surely cleaned.

  In addition, in a state where the connecting portion 75 of the stimulus applying tool B is mounted on the mounting portion 50, if a water passing space S is secured between the bottom surface of the rubbing body holder 76 and the main body case 1, the rubbing body 77 and the rubbing body The wash water that has flowed down from the body holder 76 can be reliably drained from the water flow space S. Further, it is possible to improve the ventilation of the rubbing body 77 and the rubbing body holder 76 after the cleaning, thereby promoting drying.

  In addition, when the connection portion 75 of the stimulus imparting device B is configured by a plurality of connection legs 79 and a water passage opening is provided between the connection legs 79 adjacent in the circumferential direction, the connection legs 79 and the attachment portion 50 are provided. Accordingly, the washing water can be caused to flow down quickly, and the washing water can be prevented from staying around the connecting leg 79 and the mounting portion 50.

  Further, when the impregnation body C that covers the outer surface of the skin electrode 65 is pressed and fixed with the stimulus applying tool B mounted on the mounting portion 50, it is not necessary to separately prepare a fixing tool for fixing the impregnation body C, and the skin electrode 65. The surrounding configuration can be simplified. Therefore, the periphery of the skin electrode 65 can be made compact, and usability can be improved.

There, a ring-shaped connecting portion 75 attached to the head cylinder wall 42, a ring-shaped float frame 96 surrounding the periphery of the connecting portion 75, and three ball holders 76 provided at three locations around the float frame 96. The stimulus imparting tool B is composed of the ball 77 and the like. The float structure is arranged between the previous float frame 96, the connecting portion 75 and the float frame 96, six float springs 90 for returning and urging the float frame 96 to the neutral state, and the periphery of the connecting portion 75. It is constituted by a frame support wall 101 or the like that is formed overhanging. The float spring 90 is formed of a compression coil spring, and its upper end is received by a spring receiving ring 102 fixed to the upper portion of the connecting portion 75, and its lower end is received by a ring-shaped float seat 103 protruding from the lower inner surface of the float frame 96.

It sinks into the holder 113 and gives a rubbing stimulus in cooperation with the ball 77 while rotating along the skin surface. As described above, when the ball 114 is arranged on the thermal stimulation head 15, the skin contact surface 25 rubs the skin surface to apply the thermal stimulation, and at the same time, the ball 114 rubs the skin surface to which the thermal stimulation has been applied. Since stimulation can be imparted, the beauty effect can be further improved by the synergistic effect of thermal stimulation and rubbing stimulation. In the free state, the first virtual plane H1 passing through the top of the balls 77 and 114 is positioned above the head virtual plane H passing through the top of the skin contact surface 25. Further, at the float position where the balls 77 and 114 are subjected to the skin reaction force and sink to the maximum extent in the ball holders 76 and 113, the second virtual plane H2 passing through the tops of the balls 77 and 114 is the skin contact surface 25.
