Along with the float operation of the rubbing body 77, the heat generating unit 2 and the head case 9 float and apply a rubbing stimulus 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 thermal stimulation head 15 is fixed to the head case 9. The rubbing body 77 is formed of a sphere that is rotatably supported by the rubbing body holder 76. In a state where thermal stimulation and rubbing stimulation are simultaneously applied to the skin surface, a strong rubbing stimulation is applied by the thermal stimulation head 15 and a weak rubbing stimulation is applied by the rubbing body 77.

  As shown in FIG. 14, the first virtual plane H <b> 1 passing through the top of the rubbing body 77 is positioned above the head virtual plane H passing through the top of the thermal stimulation head 15.

  The rubbing body 77 is supported by the rubbing body holder 76 so as to be able to float 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. As shown in FIG. 14, in the float position, the second virtual plane H <b> 2 that passes through the top of the rubbing body 77 is positioned the same as or below the head virtual plane H that passes through the top of the thermal stimulation head 15.

  As shown in FIG. 13, the area of the skin contact surface 25 of the thermal stimulation 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.

  The area of one rubbing body 77 in plan view is smaller than the area of the skin contact surface 25 of the thermal stimulation head 15. However, the total area of the plurality of rubbing bodies 77 in plan view is set larger than the area of the skin contact surface 25 of the thermal stimulation head 15.

  When comparing the curvature of the skin contact surface 25 of the thermal stimulation 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.

  The 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 at the bottom of the rubbing body holder 76, and the lower peripheral surface of the rubbing body 77 is exposed to the lower 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 rubbing body holder 76 and the shoulder part 48 of the head case 9.

  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.

  A skin electrode 65 for supplying current to the skin surface is provided. The skin electrode 65 also serves as the thermal stimulation head 15. The cotton mat C covering the outer surface of the thermal stimulation head 15 is pressed and fixed by the rubbing body holder 76 of the stimulus applying tool B attached to the attachment unit 50.

  In the beauty instrument according to the present invention, the thermal stimulation head 15 and the thermoelectric conversion element 17 are sandwiched and fixed by the main body case 1 and the heat sink 16. The conversion element 17 can be securely 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, and the thermoelectric conversion element 17 which are indispensable for applying heat stimulation, unnecessary parts are omitted as compared with the conventional beauty instruments, and the heat generating structure is formed. The structure can be simplified and made compact, and along with this, it is possible to reduce the size and size of the beauty device provided with the heat generating structure. Furthermore, since the heat conducted from the thermoelectric conversion element 17 to the heat sink 16 is conducted to the main body case 1 via the fastening screw 69 and can be radiated on the surface of the main body case 1, the heat dissipation effect by the heat sink 16 can be improved. For example, when the heat is conducted from the thermoelectric conversion element 17 to the heat sink 16, a part of the heat can be conducted to the main body case 1 through the fastening screw 69, so that the temperature rise of the heat sink 16 is suppressed and the heat dissipation effect is obtained. It can be improved.

  When the overhanging wall 22 is provided around the thermal stimulation head 15 and the spacer 18 is disposed between the thermal stimulation head 15 and the heat sink 16, the overhanging wall 22 is formed in a state where the heat sink 16 is fastened by the sink fastening screw 69. The assembly seat 44 and the spacer 18 can be clamped and fixed. Therefore, when the thermal stimulation head 15 is assembled to the head case 9 together with the thermoelectric conversion element 17 and the spacer 18, the thermal stimulation head 15 can be reliably prevented from wobbling and the head 15 can be securely fixed. . The spacer 18 is provided to protect the thermoelectric conversion element 17 and to prevent the thermoelectric conversion element 17 from moving when the beauty instrument receives a drop impact.

  The reason why the exhaust heat opening 39 for releasing heat is formed in the cylindrical wall of the spacer 18 surrounding the thermoelectric conversion element 17 is as follows. For example, when the operation of the Peltier element 17 is stopped while 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. However, if the exhaust heat opening 39 is formed in the cylindrical wall of the spacer 18, it is possible to quickly release the feedback heat from the exhaust heat opening 39 and prevent the Peltier element 17 from overheating.

  When the engagement recess 34 is provided in the fastening seat 29 of the heat sink 16 and the fastening seat 29 is fastened with the sink fastening screw 69 in a state where the engagement recess 34 is engaged with the screw boss 46 of the main body case 1, the heat sink 16 is moved back and forth and left and right. Can be fixed in a positioned state. Accordingly, the heat sink 16 can be fastened to the screw boss 46 accurately and firmly.

  When the heat dissipating fins 28 of the heat sink 16 are arranged between the left and right case screw bosses 55 and the left and right side surfaces of the heat dissipating fins 28 are received by the tilt regulating body 60 attached to the case screw boss 55, the heat sink 16 is attached to the gripping case 8. Can be prevented from being assembled in a tilted state. Therefore, it is possible to eliminate the variation in the quality of the beauty tool by always setting the assembly position and the assembly posture of the heat sink 16 and the gripping case 8 to be appropriate.

  When the tilt restricting body 60 is formed of an elastic material, when the radiating fin 28 is thermally expanded or thermally contracted, the deformation of the radiating fin 28 can be absorbed by being compressed or expanded and deformed. Therefore, even when the radiation fin 28 is thermally expanded or contracted due to the polarity of the drive current supplied to the thermoelectric conversion element 17, the thermal deformation of the radiation fin 28 is caused by the deformation of the tilt regulating body 60. It is possible to support the radiation fin 28 in a stable state while absorbing and preventing deformation stress from acting on the radiation fin 28.

  When the stimulus applying tool B is detachably fitted to the mounting portion 50 provided in the thermal stimulation head 15 or the head case 9, the stimulus applying tool B can be connected to the main body case 1 in a stable state. This is because the structural strength of the mounting portion 50 is strengthened by providing the mounting portion 50 on the heat stimulation head 15 that is rigid compared to other parts or the head case 9 that supports the head 15. This is because the attached stimulus imparting tool B can be firmly supported.

  When the stimulus applying device B is provided with the rubbing body 77, the thermal stimulation head 15 and the rubbing body 77 are rubbed and moved simultaneously with the skin surface, whereby the thermal stimulation and the rubbing stimulation are simultaneously applied to the skin surface. Can be granted. 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.

  According to the stimulus applicator 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 is rubbed by rotating along the skin surface. Can provide irritation. 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.

  When the rubbing body 77 is floatably supported with respect to the main body case 1 with a float structure, the rubbing body 77 floats to prevent the rubbing stimulus by the rubbing body 77 from acting excessively on the skin surface. The touch (feeling of contact) on the skin surface of the rubbing body 77 can be made 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.

  In a beauty tool that supports the rubbing body holder 76 with a float structure provided between the rubbing body holder 76 and the connecting portion 75, the rubbing body holder 76 floats to float the rubbing body 77. Therefore, compared with the case where only the rubbing body 77 floats, the degree of freedom in designing the float structure, the amount of displacement during the float, or the degree of freedom in design such as the elastic deformation force accompanying the displacement is increased. , Can promote the optimization of the float structure.

  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 a plurality of rubbing bodies 77 and rubbing body holders 76, when one rubbing body 77 floats, if the remaining rubbing body 77 is float-moved in the opposite direction, rubbing stimulation acting on the skin surface is generated. Can be diversified. Specifically, since 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 a plurality of rubbing bodies 77 can be selected, the difference in the part of the skin surface Different rubbing stimuli can be applied according to the difference in the skin condition or according to the user's preference.

  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 tilt trajectory of the rubbing body 77 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.

  In the float structure in which the float frame 96 is tiltably supported by the float shaft 99, when a plurality of rubbing bodies 77 and a rubbing body holder 76 are provided on the float frame 96, when one rubbing body 77 tilts the float, the remaining rubbing 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.

  In the beauty tool in which the entire heat generating unit 2 including the heat sink 16 is accommodated in the head case 9, the head case 9 is supported by the gripping case 8 so as to be floatable, and is pushed up and biased by the head float spring 106. Further, the stimulating device B is constituted by the connecting portion 75 attached to the head case 9 and the rubbing body holder 76 that supports the rubbing body 77, and the rubbing body 77 is supported by the rubbing body holder 76 in a floatable manner. The lift spring 90 is used to push up and bias. According to such a beauty tool, the heat generating unit 2 and the head case 9 can be floated up and down together with the floating operation of the rubbing body 77, so that the frictional stimulation by the heat generating unit 2 can be reduced.

  When the thermal stimulation head 15 is heated to a temperature higher than the temperature of the rubbing body 77 and the thermal stimulation and the rubbing stimulation are simultaneously applied to the skin surface, physical stimulation can be applied while promoting blood circulation on the skin surface. . In the case where the thermal stimulation head 15 is cooled to a temperature lower than the temperature of the rubbing body 77 and the cold stimulation and the rubbing stimulation are simultaneously applied to the skin surface, physical stimulation can be applied while tightening the skin surface.

  When the rubbing body 77 is elastically supported by the float spring 90 provided in the rubbing body holder 76, in addition to the float action of the float structure, the float action by elastic deformation of the float spring 90 can be exhibited. Accordingly, it is possible to prevent the rubbing stimulus by the rubbing body 77 from acting on the skin surface excessively, and to make the touch (contact feeling) of the rubbing body 77 to the skin surface further soft and gentle.

  According to the beauty instrument in which heat or cold is applied to the skin surface by the heat stimulation head 15 fixed to the head case 9, and the rubbing body 77 made of a sphere is rotatably supported by the rubbing body holder 76, the skin surface is heated and stimulated. In the state where the rubbing stimulus is simultaneously applied, a strong rubbing stimulus can be imparted by the thermal stimulation head 15 and a weak rubbing stimulus can be imparted by the rubbing body 77. This is because the frictional resistance generated between the rubbing body 77 and the skin surface is sufficiently smaller than the frictional resistance generated between the thermal stimulation head 15 and the skin surface. Accordingly, by properly using the thermal stimulation head 15 and the rubbing body 77 in accordance with the difference in the part of the skin surface and the skin state, it is possible to apply the 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 thermal stimulation head 15, the first virtual plane H1 and the head virtual plane H are flush with each other. Only in this state, thermal stimulation by the thermal stimulation head 15 and rubbing stimulation 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.

  When the second virtual plane H2 passing through the top of the rubbing body 77 is positioned at the same position as or below the head virtual plane H passing through the top of the thermal stimulation head 15 at the float position, the second virtual plane H2 acts on the rubbing body 77. The skin reaction force can be made the same as or slightly smaller than the skin reaction force acting on the top of the thermal stimulation head 15. Therefore, it is possible to prevent the rubbing body 77 from being excessively pressed against the skin surface, and to make the touch of the rubbing body 77 with respect to the skin surface soft and gentle, thereby giving a more delicate rubbing stimulus to the skin surface.

  When the area of the skin contact surface 25 of the thermal stimulation head 15 is set to be larger than the area of the single rubbing body 77, the skin contact surface 25 having a large area gives thermal stimulation to the skin surface, while the rubbing body 77 having a small area is used. Can rub the skin surface. According to such a beauty instrument, since a rubbing stimulus can be applied incidentally while reliably applying a thermal stimulus or a cool stimulus to the skin surface, a thermal stimulus can be mainly applied to the skin surface.

  When a plurality of rubbing bodies 77 made of spheres are rotatably supported by a rubbing body holder 76, the rubbing stimulus is applied to the skin surface by only one rubbing body 77, and the rubbing stimulation is applied to the skin surface by the plurality of rubbing bodies 77. Since the state to be applied can be selected, different rubbing stimuli can be applied according to the difference in the part of the skin surface, the difference in the skin state, or according to the user's preference.

  The area of one rubbing body 77 in plan view was made smaller than the area of the skin contact surface 25 of the thermal stimulation head 15. Furthermore, the total area of the plurality of rubbing bodies 77 in plan view was set larger than the area of the skin contact surface 25 of the thermal stimulation head 15. According to such a beauty tool, when the thermal stimulus and the rubbing stimulus are simultaneously applied to the skin surface, the stimulation degree of the rubbing stimulus by the rubbing body 77 is made larger than the stimulation degree of the thermal stimulus by the thermal stimulus head 15, A physical stimulus can be given mainly to the surface.

  When the curvature of the skin contact surface 25 of the thermal stimulation head 15 is set to be smaller than the curvature of the rubbing body 77, the contact opportunity between the skin contact surface 25 and the skin surface is increased more than the contact opportunity between the rubbing body 77 and the skin surface. Thus, the heat stimulation by the skin contact surface 25 can be accurately applied to the skin surface.

  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 lower peripheral surface of the rubbing body 77 is exposed to the lower surface side of the rubbing body holder 76, the stimulus applying tool B is washed. It is possible to facilitate the discharge of the cleaning liquid. Moreover, since it can wash | clean while pouring washing water from the upper peripheral surface of the rubbing body 77 or the exposed surface of a lower surface at the time of washing | cleaning, the whole surface of the rubbing body 77 can be wash | cleaned reliably.

  In a state where the connecting portion 75 is mounted on the mounting portion 50, if a water passing space S is secured between the rubbing body holder 76 and the shoulder portion 48 of the head case 9, it flows down from the rubbing body 77 and the rubbing body holder 76. The washed water 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.

  According to the stimulus applicator B in which the connecting portion 75 is constituted by a plurality of connecting legs 79 and a water passage opening is provided between the connecting legs 79 adjacent in the circumferential direction, the weight of the stimulus applicator B by the amount of the water passage opening. To reduce weight. Further, when the main body A is configured to be washable with water, the cleaning water is allowed to flow down quickly along the connecting leg 79 and the mounting portion 50, and the cleaning water flows to the peripheral portion of the connecting leg 79 and the mounting portion 50. It can prevent staying.

  According to the beauty instrument having the skin electrode 65 for supplying current to the skin surface and the thermal stimulation head 15 also serving as the skin electrode 65, electrical stimulation such as ion derivation action and ion introduction action is applied to the skin face. However, a rubbing stimulus can be applied with the stimulus applying tool B. Therefore, it is possible to obtain a beauty instrument having a variety of beauty functions capable of exerting further massage action by thermal stimulation by the thermal stimulation head 15, electrical stimulation by both electrodes 65 and 66, and rubbing stimulation of the stimulus applying tool B. If the thermal stimulation head 15 also serves as the skin electrode 65, it is not necessary to provide the skin electrode 65 in the heat generating unit 2, so that the structure of the beauty tool can be simplified. Furthermore, according to the beauty tool in which the cotton mat C covering the outer surface of the thermal stimulation head 15 is pressed and fixed with the rubbing body holder 76, the structure of the heat generating unit 2 can be further simplified, and the manufacturing cost of the beauty tool can be further reduced.

  The thermal stimulation head 15 is made of an aluminum die-cast molded product having excellent thermal conductivity. The head shaft 21 occupies most of the heat stimulation head 15, and a flange-shaped protruding wall 22 formed on the lower peripheral surface of the head shaft 21. The heat transfer portion 23 is provided integrally with the protruding wall 22 so as to protrude downward. The head shaft 21 is formed in a cross-sectional shape in which each apex of an equilateral triangle is rounded, a hole 24 for accommodating a thermistor 51 to be described later is formed inside the shaft, and a skin contact surface 25 is in an upwardly curved shape on the top of the shaft. Is formed. By providing the overhanging wall 22 below the head shaft 21, the overhanging wall 22 can be received and supported by the mounting seat 44 provided in the head case 9 when the heat stimulation head 15 is assembled. The head 15 can be securely fixed by preventing the head 15 from wobbling.

  In FIG. 5, the heat sink 16 is made of an aluminum die-cast molded product having excellent thermal conductivity, and includes a rectangular parallelepiped sink block 27, and a plurality of radiating fins 28 provided on the back and bottom surfaces of the sink block 27, A fastening seat 29 provided on both the left and right sides of the sink block 27, a heat transfer section 30 and a heat receiving table 31 provided on the upper surface of the sink block 27 are integrally provided. In the center of the front surface of the sink block 27, a vertical positioning groove 32 for positioning the spacer 18 is formed.

  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.

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.

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 Peltier element 17, and the spacer 18 which are indispensable for applying heat stimulation, unnecessary parts are omitted as compared with conventional beauty instruments, The structure of the heat generating structure can be simplified and made compact, and in accordance with this, the beauty device including the heat generating structure can be made smaller and more compact. Furthermore, since the heat conducted from the Peltier element 17 to the heat sink 16 can be conducted to the main body case 1 via the screw 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 ball holders (rubbing) provided at three locations around the upper portion of the connecting portion 75. Body holder) 76 and a plastic ball (rubbed body) 77 rotatably supported by the ball holder 76. The connecting portion 75 includes 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 so that the head shaft 21 can be passed through the center of the connecting end wall 78. The shaft opening 80 is formed. As shown in FIG. 14, there is a water passage opening 85 between the connecting legs 79 adjacent in the circumferential direction, and the washing water can be effectively flowed down, and the stimulus applicator B is lightened by the amount of the water passage opening 85. Can be 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 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 mat fixing tool for fixing and holding the cotton mat C covering the surface of the skin contact surface 25, and the cotton mat C is formed at the lower end of a total of six short holding cylinder walls 83. The periphery is clamped and fixed (see FIG. 14). 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.

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 provided at 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 continuously extended obliquely downward, and the support arm 89 is provided obliquely upward from the lower end of the arm base 88.
The lower peripheral surface of the ball 77 attached to the ball holder 76 is received by the tip of the support arm portion 89. 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.

  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.

  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. The curvature of the ball 77 is set large while the curvature of the skin contact surface 25 formed in an upwardly curved shape is set small. 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. Specifically, an ion introduction mode in which a weak pulse current is supplied to the first electrode 65 and the second electrode 66 in a state where the cotton mat C impregnated with a cosmetic liquid is attached to the surface of the skin contact surface 25, or Electric stimulation can be applied to the skin surface in the ion derivation mode. 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.

  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 cotton mat C and the ball 77 are applied to the face skin and rubbed, so that ion introduction can be performed and the moisturizing component of the cosmetic liquid can penetrate into the skin. At the time of ion introduction, gentle rubbing stimulation by the ball 77 can be applied to exert a massage effect. Further, a weak current can be supplied to the skin surface by grasping the gripping case 8 including the second electrode 66 and applying the first electrode 65 to the face skin to be cared for. At this time, since the first electrode 65 has a positive polarity and the second electrode 66 has a negative polarity, the cotton mat C and the ball 77 are rubbed against the face skin (skin surface) to irritate the skin surface in the ion derivation mode. Can be granted.

  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, by applying the cotton mat C and the ball 77 to the face skin and rubbing it, ions can be derived and fine stains on the face skin can be removed. At the time of deriving ions, 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. By grasping the gripping case 8 including the second electrode 66 and applying the first electrode 65 to the face skin to be cared for, a weak current can be supplied to the skin surface. At this time, since the first electrode 65 has a positive polarity and the second electrode 66 has a negative polarity, the cotton mat C and the ball 77 are rubbed against the face skin (skin surface) to irritate the skin surface in the ion derivation mode. Can be granted.

  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 face skin and rubbed to heat the skin surface. Applying and rubbing stimulation at the same time can promote blood circulation and activate facial skin. 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 heat stimulation head 15 cooled to a temperature lower than the temperature of the ball 77, the skin contact surface 25 of the heat stimulation head 15 and the ball 77 are simultaneously applied to the face skin and rubbed to thereby cool the skin surface. Applying and rubbing stimulation at the same time can tighten the facial skin. 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 Peltier element 17 as well as the heat generated by the Peltier element 17 can be applied to the skin surface by the thermal stimulation head 15, the thermal effect 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 the first embodiment, a plurality of receiving arms 87 are provided on the rubbing body holder 76, and the ball (rubbing body) 77 is float-supported by using this as a float spring 90. However, the receiving arms 87 may be provided on the rubbing body 77 side. it can. For example, the rubbing body 77 is formed of a cylindrical body (tubular body) having a hemispherical rubbing surface, and a receiving arm 87 is integrally provided at the lower end thereof. Further, a receiving wall is provided below the holding cylinder walls 82 and 83, and the free end of the receiving arm 87 is supported by the receiving wall.
