(Embodiment 1)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The beauty device according to the present embodiment repeatedly presses and picks up the skin by reciprocating the surface of the skin with the ball (contact part) pressed against the skin. Thereby, it is possible to perform skin massage.

As shown in FIG. 1, this beauty apparatus includes a handle 10, a pair of

balls

13A and 13B, a heater 131 that heats the

balls

13A and 13B, and

vibration devices

121A and 121B. The beauty device also includes a battery (power source) 111 and a drive circuit board 112 that receives power supply from the battery 111 and drives the heater 131 and the

vibration devices

121A and 121B. The handle 10 includes a grip portion 11 that is gripped by a user when in use, and support

portions

12A and 12B that support the pair of

balls

13A and 13B, respectively.

The gripping part 11 is formed of a synthetic resin or the like and is a box having an outer shape that is substantially Y-shaped. A power switch 14 for turning on and off the heater 131 and the vibration devices 121 A and 121 B is provided in a part of the grip portion 11. When the user grips the grip portion 11, the power switch 14 is pressed by the user's palm or the like and is turned on.

The

support portions

12A and 12B have

balls

13A and 13B rotatably provided at one end portion, and the other end portion is supported swingably by the grip portion 11. As shown in FIG. 2, the support portion 12 A is fixed to the grip portion 11 via a vibration isolation member 17. The vibration isolation member 17 is made of an elastic material such as rubber, and transmission of vibration of the support portion 12A to the grip portion 11 is suppressed. Similarly to the support portion 12A, the support portion 12B is also fixed to the grip portion 11 via the vibration isolating member 17.

The

balls

13A and 13B are made of isotropic high density graphite and are substantially spherical. The

balls

13A and 13B are manufactured by a manufacturing method similar to the manufacturing method of “carbon molded body” described in, for example, the document: Japanese Patent Application Laid-Open No. 2012-100777. As shown in FIG. 1, the

balls

13A and 13B are rotatable around the rotation axes J11 and J12, respectively. The ball 13A has a recessed portion 132A that is partially recessed along the ball rotation axis J11. The ball 13 A is fixed to the support portion 12 A via the bearing 15 at the opening end portion of the recess portion 132 A. Also, the ball 13B has the same structure as the ball 13A and is fixed to the support portion 12B via a bearing.

The heater 131 heats the ball 13A to a temperature equal to or higher than a preset reference temperature. The reference temperature is set to 37 ° C. ± 1 ° C., for example. The heater 131 is composed of a constant temperature heating element having an automatic temperature control function, such as a PTC (Positive Temperature Coefficient) thermistor. In addition, as the heater 131, you may be comprised from the series circuit of the PTC thermistor arrange | positioned around a resistance heater and a resistance heater, for example. Since the heater 131 is configured using a PTC thermistor having an automatic temperature control function, it is not necessary to provide a temperature control function to the drive circuit board 112. Therefore, there is an advantage that the configuration of the drive circuit board 112 can be simplified. Moreover, the heater 131 is arrange | positioned inside the hollow part 132A of the ball | bowl 13A, as shown in FIG. As a result, the heat generated in the heater 131 can be efficiently transmitted to the rotor 13A, so that the loss of power supplied from the drive circuit board 112 to the heater 131 can be reduced.

As shown in FIG. 1, the vibration devices 121 A and 121 B are disposed inside the support portions 12 A and 12 B of the handle 10. As shown in FIG. 2, the vibration device 121 A includes a motor 122, an eccentric weight 123, and a casing 124. The eccentric weight 123 is fixed to the shaft 122b of the motor 122. The main body 122 a of the motor 122 is fixed to the casing 124. The casing 124 is fixed to the support portion 12 A via the fixing member 16. The fixing member 16 is made of a resin material having higher rigidity than rubber. When the motor 122 operates, the eccentric weight 123 fixed to the shaft 122b rotates to generate vibration. The vibration generated by the vibration device 121A is transmitted to the ball 13A via the fixing member 16 and the support portion 12A, and the ball 13A vibrates. The vibration device 121B has the same configuration as that of the vibration device 121A. The vibration generated by the vibration device 121B is transmitted to the ball 13B, and the ball 13B vibrates. On the other hand, since the vibration isolating member 17 is interposed between the

support portions

12A and 12B and the grip portion 11, vibration generated by the

vibration devices

121A and 121B is difficult to be transmitted to the grip portion 11. Thereby, at the time of use of a beauty device, the discomfort given to a user by vibration of grasping part 11 can be reduced.

The drive circuit board 112 includes a heater drive circuit (heater drive unit) 112a that drives the heater 131, and a vibration device drive circuit (vibration device drive unit) 112b that drives the vibration device 121A. The heater drive circuit 112a is connected to the heater 131 via a power supply line L1 laid inside the support portion 12A. The vibration device drive circuit 112b is connected to the

vibration devices

121A and 121B via power supply lines L21 and L22. The heater drive circuit 112 a is configured by a DC-DC converter that boosts or lowers the voltage input from the battery 111 and outputs the boosted voltage to the heater 131. The vibration device drive circuit 112b is also configured by a DC-DC converter that boosts or decreases the voltage input from the battery 111 and outputs the voltage to the

vibration devices

121A and 121B. The power switch 14 is inserted in the power supply path from the battery 111 to the heater drive circuit 112a and the vibration device drive circuit 112b.

Next, a method for using the beauty device according to the present embodiment will be described. First, the grip part 11 of the handle 10 of the beauty apparatus is gripped. Then, the power switch 14 is pressed and turned on, and the heater 131 and the

vibration devices

121A and 121B operate. Thereby, the ball 13A is heated to a temperature equal to or higher than the reference temperature, and both the

balls

13A and 13B vibrate. Then, with the

balls

13A and 13B pressed against the skin, the beauty device is reciprocated in the direction indicated by the arrow AR2 in FIG. This makes it possible to repeatedly press and pick the skin while warming the skin with far infrared rays emitted from the heated ball 13A and applying vibration to the skin.

As described above, according to the beauty device according to the present embodiment, the ball 13A is formed from isotropic high-density graphite, and the heater 131 warms the ball 13A. Accordingly, by reciprocating the surface of the skin with the ball 13A pressed against the skin, the skin can be massaged while warming the skin with the far infrared rays emitted from the ball 13A. Therefore, the effect of promoting blood circulation in the skin can be enhanced.

(Embodiment 2)
The beauty device according to the present embodiment includes a cooler that cools the ball (second contact portion) 13B in addition to the heater 131 that heats the ball (first contact portion) 13A. The skin can be given a cool feeling by being brought into contact with the skin.

As shown in FIG. 3, the beauty device includes a cooler 232 and a heat sink 218 for releasing heat discharged from the cooler 232 to the outside. In FIG. 3, the same components as those in the first embodiment are denoted by the same reference numerals. The driving circuit board 212 of the beauty device receives the power supply from the battery 111 and drives the cooler 232. By providing the heat sink 218 in this manner, heat discharged from the cooler 232 is prevented from accumulating in the beauty apparatus, and the cooling efficiency of the balls 13B by the cooler 232 is improved.

The handle 210 includes the grip portion 11 and

support portions

12A and 212B. A window 212a for exposing a part of the heat sink 218 is formed in a part of the support 212B. A part of the grip 11 is provided with a slide type changeover switch 214 for switching between a state in which the heater 131 is operated and a state in which the cooler 232 is operated. When the knob portion 214a of the changeover switch 214 is slid to the upper side in FIG. 3, the heater 131 is activated, and when the knob portion 214a is slid to the lower side in FIG. 3, the cooler 232 is activated. . FIG. 3 shows a state where the cooler 232 operates.

As shown in FIG. 4, the ball 13 B has a recessed portion 132 B that is recessed along the rotation axis J 12 of the ball 13 B. In FIG. 4, the same components as those in the first embodiment are denoted by the same reference numerals. In addition, a heat insulating member 219 for shielding heat transfer between the recessed portion 132B and the heat sink 218 is disposed at the tip of the support portion 212B.

As shown in FIG. 3, the cooler 232 cools the other balls 13 B excluding the balls (first balls) 13 A heated by the heater 131. As shown in FIG. 4, the cooler 232 includes a Peltier element 232a and a heat transfer section 232b. The Peltier element 232a is a flat plate-like thermoelectric conversion element that utilizes the Peltier effect that heat is biased when current flows through a junction between two kinds of metals or semiconductors. As this Peltier element 232a, for example, an element in which the temperature difference between the heat absorbing portion 232c and the heat generating portion 232d when current is passed is about 30 ° C. can be employed. The heat transfer part 232b is formed in a rod shape from a metal such as copper or graphite. The heat transfer portion 232b is disposed inside the hollow portion 132B of the ball 13B, and a part of the heat transfer portion 232b is in contact with the heat absorption portion 232c of the Peltier element 232a. Thereby, the heat absorption part 232c of the Peltier element 232a is thermally coupled via the air present in the ball 13B, the heat transfer part 232b, and the recess part 132B. Further, since the heat transfer part 232b is arranged inside the hollow part 132B of the ball 13B, the heat of the ball 13B can be efficiently transferred to the heat transfer part 232b. Therefore, loss of power supplied from the drive circuit board 212 to the Peltier element 232a can be reduced.

The heat sink 218 is formed of a metal such as copper or graphite, and is in contact with the heat generating portion 232d of the Peltier element 232a and a part thereof is exposed to the outside. A thermistor (not shown) for controlling the temperature of the heat absorbing portion 232c of the Peltier element 232a is disposed in the vicinity of the contact portion between the heat sink 218 and the heat generating portion 232d of the Peltier element 232a. In addition, the heat sink 218 may be comprised from the laminated body formed by laminating | stacking the graphite sheet formed, for example from the expanded graphite.

The drive circuit board 212 includes a heater drive circuit 112a, a vibration device drive circuit 112b, and a cooler drive circuit (cooler drive unit) 112c. The cooler driving circuit 112 c receives power supply from the battery 111 and drives the cooler 232. The cooler drive circuit 112c is connected to the Peltier element 232a via the power supply line L3 laid inside the support portion 12B. The cooler driving circuit 112c includes a DC-DC converter that boosts or lowers the voltage input from the battery 111 and outputs the boosted voltage to the Peltier element 232a, and a control circuit that controls on / off of the DC-DC converter. The control circuit controls the DC-DC converter on and off based on the resistance value of the thermistor for temperature control of the heat absorption part 232c of the Peltier element 232a, so that the temperature of the heat absorption part 232c is in a temperature range of, for example, 8 ° C to 20 ° C To maintain.

When the power switch 14 is turned on, the changeover switch 214 connects the output terminal on the high potential side of the battery 111 between the input terminal on the high potential side of the heater drive circuit 112a and the input terminal on the high potential side of the cooler drive circuit 112c. It is provided so as to be electrically connected to either. Thereby, the changeover switch 214 switches the power supply destination of the battery 111 to either the heater drive circuit 112a or the cooler drive circuit 112c when the user performs a slide operation.

Next, a method for using the beauty device according to the present embodiment will be described. In the state where the knob portion 214a of the changeover switch 214 is slid to the upper side in FIG. 3, the grip portion 11 of the handle 10 of the beauty device is gripped. Then, the power switch 14 is turned on, and the heater 131 and the

vibration devices

121A and 121B are activated. On the other hand, the grip part 11 of the handle 10 of the beauty device is gripped in a state in which the knob part 214a of the changeover switch 214 is slid downward in FIG. Then, the power switch 14 is turned on, and the cooler 232 and the

vibration devices

121A and 121B are activated. As a result, the ball 13B is cooled and both the

balls

13A and 13B vibrate. Then, with the

balls

13A and 13B pressed against the skin, the beauty device is reciprocated in the direction indicated by the arrow AR2 in FIG. Accordingly, the skin can be repeatedly pressed and picked up while vibration is applied to the skin while the skin is cooled by the cooled balls 13B.

As described above, the beauty device according to the present embodiment includes the cooler 232 that cools the ball 13B. Accordingly, by reciprocating the surface of the skin with the ball 13B pressed against the skin, the skin can be massaged while cooling the skin with the ball 13B. Therefore, for example, when a beauty device is used in a hot summer season, there is an advantage that the user can comfortably massage by giving a cool feeling to the user's skin.

(Embodiment 3)
The beauty device according to the present embodiment is configured to include the heater 131 as in the beauty device described in the first embodiment, and includes a non-contact power supply module that supplies power to the heater 131.

In FIG. 5, the same reference numerals as those in FIG. In addition, the heater 131 is fixed to the ball 13 A via a heat transfer member 334. The heat transfer member 334 is provided so as to fill a region between the inner wall of the recessed portion 132 A and the outer surface of the heater 131. The heat transfer member 334 is made of, for example, an adhesive containing a silicone resin or a metal filler. Thereby, compared with the structure which has a space | gap between the inner wall of the hollow part 132A, and the outer surface of the heater 131 like the beauty apparatus which concerns on Embodiment 1, the thermal coupling strength of the heater 131 and the ball | bowl 13A is strengthened. be able to.

The non-contact power supply module 330 supplies power by a so-called electromagnetic induction method. The power feeding unit 333 supplies the power supplied from the heater driving unit 112a to the power receiving unit 332 in a non-contact manner. As shown in FIG. 6, the power feeding unit 333 includes an inverter circuit 333a connected to the heater drive circuit 112a and a coil L301 to which alternating current is supplied from the inverter circuit 333a. The inverter circuit 333a converts the direct current supplied from the heater drive circuit 112a into alternating current and outputs the alternating current to the coil L301.

The power reception unit 332 is electrically connected to the heater 131 and supplies the received power to the heater 131. The power receiving unit 332 includes a coil L302 that is magnetically coupled to the coil L301, a resonance capacitor C1 that is connected in parallel to the coil L302, a rectifier circuit BR, and a smoothing capacitor C2. A heater 131 is connected between both ends of the capacitor C2. The alternating current generated in the coil L301 is rectified by the rectifier circuit BR and smoothed by the smoothing capacitor C2.

As described above, the beauty device according to the present embodiment can rotate the heater 131 connected to the power receiving unit 332 with respect to the power feeding unit 333 fixed to the support unit 12A. Thereby, since the heater 131 can be fixed to the ball 13A via the heat transfer member 334, the thermal coupling strength between the heater 131 and the ball 13A can be increased. Therefore, since the heat transfer efficiency from the heater 131 to the ball 13A is improved, there is an advantage that power consumption in the heater 131 can be reduced.

(Embodiment 4)
The beauty device according to the present embodiment includes a cooler 432, a non-contact power supply module that supplies power to the cooler 432, and a cooling fan that releases heat discharged from the cooler 432 to the outside. .

As shown in FIG. 7, this beauty device includes a non-contact power supply module 430 having a power reception unit 433 and a power supply unit 434, and a cooling fan 435. In FIG. 7, the same reference numerals as those in FIG. 3 are assigned to the same configurations as those in the second embodiment. The cooler 432 includes a Peltier element 232a and a heat transfer unit 432b. The cooler 432 is fixed to the ball 13B in a state where a part of the heat transfer portion 432b is in surface contact with the inner wall of the recess portion 132B of the ball 13B. The heat transfer part 432b is made of a metal such as copper or graphite. Thereby, compared with the structure which has a space | gap between the inner wall of hollow part 132A, and the outer surface of the heat-transfer part 232b like the beauty apparatus which concerns on Embodiment 2, the heat coupling | bond part of the heat-transfer part 232b and the ball | bowl 13B is compared. Strength can be increased.

The power reception unit 433 is electrically connected to the cooler 432 and supplies the received power to the cooler 432. The power feeding unit 434 supplies the power supplied from the cooler driving unit 112c to the power receiving unit 433 in a non-contact manner. The circuit configurations of the power receiving unit 433 and the power feeding unit 434 are the same as the circuit configurations of the power receiving unit 332 and the power feeding unit 333 illustrated in FIG. 6, respectively. The non-contact power supply module 430 corresponds to a configuration in which the heater 131 is replaced with the Peltier element 232a and the heater driving circuit 112a is replaced with the cooler driving circuit 112c in the circuit diagram shown in FIG.

As shown in FIG. 8, the power receiving unit 433 has a substantially annular shape disposed so as to surround the substantially disc-shaped Peltier element 232 a. The power receiving coil L422 is disposed along the circumferential direction of the power receiving unit 433. The power receiving unit 433 rotates around the axis J12 together with the Peltier element 232a. On the other hand, the coil (not shown) of the power feeding unit 434 is arranged so that the central axis thereof substantially coincides with the central axis of the coil L422.

The fan 435 is composed of a small axial flow fan, and as shown in FIG. 7, is operated to receive power supply from the cooler drive circuit 112c and is arranged to blow air to the heat generating portion 232d of the Peltier element 232a. The fan 435 is attached to an opening 412b provided in a part of the support 412B. A vent hole 412a is provided in a portion of the support portion 412B that faces the opening 412b. The air discharged from the fan 435 flows to the vent hole 412a through the vicinity of the heat generating portion 232d of the Peltier element 232a. Thereby, the heat generating part 232d of the Peltier element 232a is cooled by exchanging heat with the air discharged from the fan 435.

As described above, since the beauty device according to the present embodiment has a configuration that does not include a heat sink, there is an advantage that the weight can be reduced. Further, since the thermal coupling strength between the heat transfer portion 432b of the cooler 432 and the ball 13B can be increased, the heat transfer efficiency from the ball 13B to the heat transfer portion 432b is improved, and consequently the power consumption in the cooler 432 is reduced. There is an advantage that reduction can be achieved.

Alternatively, the ball may have a metal layer formed on the surface of the substrate by metal plating. According to this structure, there exists an advantage that the designability of a ball and by extension, the designability of the beauty device whole improve. In addition, when the surface of the ball body is coated with a DLC book film, there is an advantage that rough skin is suppressed because the burden on the skin during massage is reduced.

Further, the surface of the ball made of isotropic graphite has a silver-based inorganic antibacterial agent made of an inorganic ion exchanger carrying silver ions (for example, a silver-based inorganic antibacterial agent “NOVALON (registered trademark)” manufactured by Toagosei Co., Ltd.). ) May be covered with a film of dispersed material. As the material in which the silver-based inorganic antibacterial agent is dispersed, a resin material such as an acrylic resin or a polypropylene resin can be employed. The proportion of the silver-based inorganic antibacterial agent contained in the coating film may be about 1%. According to this configuration, since the growth of fungi such as Escherichia coli and Salmonella on the ball surface can be suppressed, there is an advantage that the ball surface can be kept clean.

In the third and fourth embodiments, the example of the beauty device including both the heater 131 and the

coolers

232 and 432 has been described. However, the beauty device is not limited thereto, and may be a beauty device including only the

coolers

232 and 432, for example.

Embodiments 3 and 4 have described examples in which the non-contact

power supply modules

330 and 430 supply power by a so-called electromagnetic induction method, but the power supply method is not limited to this. For example, a non-contact power supply module that supplies power by a so-called electric field coupling method, a so-called magnetic field resonance method, or a so-called radio wave method may be employed.

In the fifth embodiment, the surface of the ball formed from isotropic graphite has been subjected to blasting, and the structure in which the deodorant mainly composed of an artificial enzyme is adsorbed on the surface has been described. However, the present invention is not limited to this, and the ball surface may not be blasted and the deodorant may not be adsorbed. Even in this configuration, by reciprocating the surface of the skin with the ball pressed against the skin, the skin can be massaged while warming the skin with far infrared rays emitted from the ball. Therefore, the effect of promoting blood circulation in the skin can be enhanced.

In each of the embodiments, the example in which the

balls

13A and 13B are formed from isotropic graphite has been described. However, the present invention is not limited thereto, and for example, the

balls

13A and 13B are formed from a composite material of carbon powder and a resin material. May be. As this composite material, for example, a composite material containing 60 to 80% by weight of carbon powder can be adopted. In this case, the

balls

13A and 13B can be manufactured using an injection molding method. Further, the

balls

13A and 13B may be formed, for example, by sintering a mixture of carbon fibers and a resin material.

As mentioned above, although each embodiment and modification of this invention (including what was written in the description, the same is true hereafter) were described, this invention is not limited to these. The present invention includes a combination of the embodiments and modifications as appropriate, and a modification appropriately added thereto.
