[0003] [Patent Document 1] Japanese Patent Application Publication No. 2017-221564 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned beauty device, the Peltier element is located away from the vibration plate, which reduces the efficiency of heat transfer from the Peltier element to the vibration plate. On the other hand, if the Peltier element is attached to the vibration plate together with the vibrator, there is a risk that the vibration of the vibration plate will be uneven depending on the position of the vibrator.

[0005] The present invention has been made in consideration of these points, and aims to appropriately adjust the temperature and vibration of the head of a beauty device. [Means for solving the problem]

[0006] In one aspect of the present invention, a cosmetic device is provided that includes a cylindrical head that can come into contact with the skin on the surface of one end in the axial direction, a temperature adjustment body that is fixed to the back surface of the one end of the head opposite the surface and heats the head, a flange portion that extends outward from the other axial end of the head, and a vibrator that is fixed to the flange portion and vibrates the head.

[0007] The flange portion may extend in an annular shape from the other end of the cylindrical head, and the vibrator may have an annular shape.

[0008] The head may further comprise a housing having an opening in which the head is attached, and the flange portion may be engaged with an engaged portion provided in the opening.

[0009] The flange portion may have an engagement surface that engages with the engaged portion, and a fixing surface that is located on the opposite side to the engagement surface and to which the vibrator is fixed.

[0010] The temperature adjusting body may further include a metal heat absorbing block capable of cooling the head, located on the opposite side of the temperature adjusting body from the one end, and absorbing heat from the temperature adjusting body.

[0011] The axial length of the heat absorbing block may be greater than the axial length of the head, and the vibrator may surround the heat absorbing block.

[0012] The heat absorbing device may further include a heat conductive material sandwiched between the heat absorbing block and the temperature adjusting body, for conducting heat from the temperature adjusting body to the heat absorbing block.

[0013] In addition, the end face of one axial end of the heat absorption block faces the temperature adjustment body, and the other axial end of the heat absorption block is not supported by any other member, and the heat absorption block may further include a resin material filling the gap between the outer peripheral surface of the one axial end of the heat absorption block, the inner peripheral surface of the head, and the back surface of the one axial end. [Effects of the Invention]

[0014] According to the present invention, it is possible to appropriately adjust the temperature and vibration of the head of the cosmetic device. [Brief explanation of the drawings]

[0016] <Beauty device configuration> The configuration of a beauty device 1 according to one embodiment will be described with reference to FIGS. Fig. 1 is a perspective view showing a beauty device 1 according to one embodiment. Fig. 2 is a schematic diagram showing the internal configuration of the beauty device 1. Figs. 3 and 4 are perspective views showing the configuration of a head 20 and its surroundings. Fig. 5 is a schematic diagram showing the cross-sectional configuration of the head 20 and its surroundings. Fig. 6 is a schematic diagram showing the head 20, vibrator 30, temperature adjuster 40, and heat absorbing block 45 in a separated state.

[0017] The beauty device 1 is used for beautifying the skin of a user. The beauty device 1 has the function of applying ultrasonic vibrations to the skin of the user, heating the skin, and cooling the skin. Applying ultrasonic vibrations to the skin has the effect of activating metabolism and promoting blood circulation. The beauty device 1 is sized so that the user can hold it in one hand.

[0018] As shown in FIG. 2, the cosmetic device 1 includes a housing 10, a head 20, a vibrator 30, a temperature adjuster 40, a heat absorbing block 45, a heat conductive material 48, a battery 80, and a control board 90.

[0019] The housing 10 is made of, for example, resin. As shown in FIG. 1, the housing 10 has a structure in which an upper case 11 and a lower case 12 are stacked on top of each other. As shown in FIG. 2, a control board 90 and the like are provided in the internal space surrounded by the upper case 11 and the lower case 12. An operation switch 18 that is operated by the user is provided on the lower case 12 side. For example, the operation switch 18 includes a switch that selects the operation of the vibrator 30. The operation switch 18 also includes a switch that selects a heating mode for heating the head 20 and a switch that selects a cooling mode for cooling the head 20.

[0020] The housing 10 has an attachment portion 13 for detachably attaching the head 20. As shown in FIG. 2, the attachment portion 13 is provided at one longitudinal end of the lower case 12. An opening 14 is provided at the tip of the attachment portion 13, into which the head 20 is attached. A circular opening having the same outer shape as the head 20 is formed in the opening 14. An engaged portion 16 with which the head 20 engages is provided at the edge of the opening 14.

[0021] The head 20 is the part that comes into contact with the user's skin. The surface 21a of the tip 21, which is one end in the axial direction of the head 20, can come into contact with the skin. The head 20 is made of a metal with high thermal conductivity (titanium, for example). The head 20 is formed into a cylindrical shape from a metal plate. Specifically, the head 20 has a hat shape. The head 20 has a flange portion 22 that is attached to the opening 14.

[0022] As shown in Fig. 5, the flange portion 22 extends outward from the other axial end of the head 20. Specifically, the flange portion 22 extends radially outward from the other end. As shown in Fig. 6, the flange portion 22 extends in an annular shape from the other end of the cylindrical head 20. The flange portion 22 engages with the engaged portion 16 provided in the opening 14.

[0023] The flange portion 22 has an engagement surface 23 that engages with the engaged portion 16, and a fixing surface 24 to which the vibrator 30 is fixed. A packing 26 serving as a seal member is provided between the engagement surface 23 and the engaged portion 16. The fixing surface 24 is a surface located opposite the engagement surface 23.

[0024] The vibrator 30 is, for example, an ultrasonic vibrator, and vibrates the head 20. The vibrator 30 is, for example, made of a piezoelectric element. Ultrasonic vibrations generated from the vibrator 30 are transmitted to the user's skin via the head 20. The vibrator 30 has a circular ring shape as shown in FIG. 6. The vibrator 30 is provided in a position facing the flange portion 22 of the head 20 as shown in FIG. 5, and vibrates the flange portion 22. An insulating plate 35 is provided between the vibrator 30 and the flange portion 22.

[0025] The vibrator 30 has a circular ring shape similar to the flange portion 22, and therefore vibrates the entire flange portion 22. By vibrating the entire flange portion 22, uneven vibration does not occur in the head 20, and the head 20 tends to vibrate uniformly.

[0026] The vibrator 30 is fixed to the fixing surface 24 of the flange portion 22. Specifically, the vibrator 30 is fixed to the fixing surface 24 with an insulating plate 35 sandwiched therebetween. By fixing the vibrator 30 to the flange portion 22 that engages with the engaged portion 16 of the housing 10, the space around the flange portion 22 can be effectively utilized to arrange the vibrator 30, and therefore the head 20 that protrudes from the housing 10 can be made smaller (in other words, the outer diameter of the head 20 can be reduced).

[0027] The temperature adjuster 40 is a thermoelectric element, and one example is a Peltier element. The temperature adjuster 40 heats the head 20. Specifically, the temperature adjuster 40 heats the tip 21 of the head 20. The temperature adjuster 40 can also cool the tip 21 of the head 20. Specifically, the head 20 is heated by the heat generation effect of the temperature adjuster 40, and the head 20 is cooled by the heat absorption effect of the temperature adjuster 40.

[0028] The temperature adjusting member 40 is in contact with the head 20. Specifically, as shown in Fig. 5, the temperature adjusting member 40 is fixed to the back surface 21b opposite to the front surface 21a (the surface that comes into contact with the user's skin) of the tip portion 21 of the head 20. By having the temperature adjusting member 40 in direct contact with the head 20 in this way, the efficiency of heat transfer is improved, and the temperature adjusting member 40 can efficiently heat and cool the head 20.

[0029] The heat absorption block 45 has the function of absorbing heat from the temperature adjustment body 40. Specifically, the heat absorption block 45 absorbs heat from the temperature adjustment body 40 when the temperature adjustment body 40 absorbs heat from the head 20. In this embodiment, in order to provide the heat absorption block 45, a cooling fan is not provided inside the housing 10. In other words, the heat absorption block 45 functions as a fan. Since a fan is not provided inside the housing 10, there is no need to provide an inlet through which the fan draws in air and an outlet through which air is discharged in the housing 10, thereby improving the design of the housing 10. Furthermore, since there is no inlet, it is possible to prevent water from entering from the outside via the inlet.

[0030] The heat absorption block 45 is a metal block. The heat absorption block 45 is larger than the head 20. Specifically, the axial length of the heat absorption block 45 is larger than the axial length of the head 20. By providing such a large heat absorption block 45, the heat absorption block 45 can appropriately absorb the heat of the temperature adjustment body 40 even if the heat absorption time by the temperature adjustment body 40 becomes long.

[0031] 5, the heat absorption block 45 is provided on the opposite side of the temperature adjustment body 40 from the tip portion 21 of the head 20. Specifically, an end face 46 of one axial end of the heat absorption block 45 faces the temperature adjustment body 40. As a result, the heat absorption block 45 absorbs heat from the temperature adjustment body 40 via the end face 46 of one end.

[0032] The heat absorption block 45 is fixed to the head 20 via the temperature adjusting member 40. Specifically, one axial end of the heat absorption block 45 is fixed to the head 20 via the temperature adjusting member 40. On the other hand, the other axial end of the heat absorption block 45 is not supported by any other member. Specifically, as shown in FIG. 5 , the other end of the heat absorption block 45 is spaced apart from the support plate 72 that supports the motor 70. Therefore, the heat absorption block 45 is cantilevered by the head 20.

[0033] 5, the other axial end of the heat absorption block 45 is located further inside the housing 10 than the flange portion 22 of the head 20. The heat absorption block 45 is surrounded by the vibrator 30 fixed to the flange portion 22. Specifically, the center portion of the heat absorption block 45 in the axial direction is surrounded by the vibrator 30.

[0034] 5, the heat conductive material 48 is sandwiched between the heat absorption block 45 and the temperature adjustment body 40. The heat conductive material 48 is made of a material that conducts heat, and conducts the heat of the temperature adjustment body 40 to the heat absorption block 45. The heat conductive material 48 is made of, for example, an adhesive sheet, and fixes the heat absorption block 45 and the temperature adjustment body 40 together.

[0035] The battery 80 is a rechargeable storage battery, and supplies power to each part of the cosmetic device 1. The control board 90 controls the operation of the cosmetic device 1. For example, the control board 90 operates the vibrator 30 to vibrate the head 20. The control board 90 also operates the temperature adjuster 40 to execute a heating mode for heating the head 20 and a cooling mode for cooling the head 20.

[0036] <Regarding the positional relationship between the vibrator 30, the temperature adjusting body 40, and the heat absorbing block 45> As described above, the temperature adjusting member 40 is in contact with the rear surface 21b of the tip portion 21 of the head 20 in order to efficiently heat and cool the head 20. In order to more efficiently heat and cool the head 20, it is desirable to provide the temperature adjusting member 40 over a wide area of ​​the rear surface 21b.

[0037] If the temperature adjuster 40 is provided on the back surface 21b of the tip portion 21 of the head 20, it is difficult to secure space on the back surface 21b to provide the vibrator 30. It may be possible to arrange the vibrator 30 in the limited space on the back surface 21b, but in this case, disposing the vibrator 30 in a portion of the space is likely to cause uneven vibration of the head 20 by the vibrator 30. Furthermore, if the temperature adjuster 40 and the vibrator 30 are provided on the back surface, there is a risk that the temperature adjuster 40 will move away from the head 20 when the vibrator 30 vibrates.

[0038] In contrast, in this embodiment, the vibrator 30 is provided on a flange portion 22 formed at the other end of the head 20, away from the tip (one end in the axial direction). In this case, the vibrator 30 can be disposed even if the tip of the head 20 is made smaller. Furthermore, since the vibrator 30 vibrates the flange portion 22, the entire head 20 vibrates uniformly, thereby suppressing the occurrence of uneven vibration. Furthermore, since the vibrator 30 is separated from the temperature adjusting body 40, it is possible to suppress the vibration of the vibrator 30 being transmitted to the temperature adjusting body 40 and causing adverse effects (for example, the temperature adjusting body 40 becoming separated from the head 20, making it impossible for the temperature adjusting body 40 to properly heat or cool the head 20). Furthermore, the thermal response time of the head 20 can be accelerated.

[0039] Furthermore, in this embodiment, the vibrator 30 is arranged to surround the heat absorption block 45. As a result, even if the heat absorption block 45 is lengthened to increase the heat absorption efficiency, the heat absorption block 45 does not interfere with the vibrator 30. On the other hand, even if the vibrator 30 is arranged to surround the heat absorption block 45, it is easy to vibrate the head 20 uniformly by vibrating the flange portion 22.

[0040] <Modification> In the above description, one axial end of the heat absorption block 45 is fixed to the head 20 via the temperature adjustment body 40, but this is not limiting. For example, as in the modified example shown in Fig. 7, a resin material 60 may be provided around one axial end of the heat absorption block 45 to fix it to the head 20.

[0041] 7 is a schematic diagram showing a modified example, in which an end face 46 on one axial end side of the heat absorption block 45 is fixed to the temperature adjustment body 40, and in addition, a resin material 60 is provided around one axial end of the heat absorption block 45.

[0042] 7, the resin material 60 fills the gap between the outer peripheral surface 47 of one end of the heat absorbing block 45, the inner peripheral surface 21c of the head 20, and the back surface 21b of the tip portion 21. For example, the resin material 60 is filled in tightly between the outer peripheral surface 47 of the heat absorbing block 45 and the inner peripheral surface 21c and back surface 21b of the head 20. As a result, one end of the heat absorbing block 45 is supported by the resin material 60, so that the heat absorbing block 45 does not displace even when the vibrator 30 vibrates, and the heat absorbing block 45 can easily maintain contact with the temperature adjuster 40. In particular, when the other axial end of the heat absorbing block 45 is not supported, providing the resin material 60 more effectively maintains the heat absorbing block 45 in a stable position.

[0043] <Effects of this embodiment> The cosmetic device 1 of the above-described embodiment has a temperature adjusting body 40 fixed to the back surface 21b of the tip portion 21 of the cylindrical head 20 to heat the head 20, a flange portion 22 extending outward from the other axial end of the head 20, and a vibrator 30 fixed to the flange portion 22 to vibrate the head 20. This allows the vibrator 30 to be appropriately positioned even when the temperature adjuster 40 is provided on the back surface 21b of the small head 20. Furthermore, the vibrator 30 vibrates the flange portion 22, causing the entire head 20 to vibrate uniformly, thereby preventing uneven vibration. As a result, temperature adjustment by the temperature adjuster 40 of the head 20 and vibration by the vibrator 30 can be performed appropriately.

For example, all or part of the device can be configured by functionally or physically distributing or integrating any unit. Furthermore, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention.
