[0010] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted.

[0011] It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] As shown in FIG. 1, the facial beauty device 1 according to this embodiment includes a mask body 10 that can be attached to the face, and a treatment structure 20 that is provided on the mask body 10 and is capable of performing skin treatment.

[0013] In this embodiment, the treatment structure 20 is supplied with power to operate, so that the treatment structure 20 performs a treatment on the skin.

[0014] Specifically, the facial beauty device 1 includes a controller 100, and the controller 100 is electrically connected to the treatment structure 20 so that power is supplied to the treatment structure 20.

[0015] In this embodiment, controller 100 comprises a controller body 110 and a cap 120 that is removably attached to controller body 110.

[0016] Here, the controller main body 110 incorporates a battery 130 as a power supply unit that supplies power (electricity) to the treatment structure 20 (the electrode section 40 and the heating section 30 described below), and a control board 140 as a control unit that controls the electrode section 40 and the heating section 30. The battery 130 is electrically connected to the control board 140, and the control board 140 is electrically connected to a connector 111 provided on the controller main body 110. The controller main body 110 also includes a switch button 150 for turning the power on and off, and controlling the output level and operation timing of the electrode section 40, etc.

[0017] On the other hand, the cap 120 is provided with a connector (not shown) that detachably fits into the connector 111 of the controller body 110. One end of a cable 101 electrically connected to the treatment structure 20 is attached to this connector (not shown). That is, the cable 101 is electrically connected to a connector (not shown) of the cap 120.

[0018] By engaging the connector of the cap 120 with the connector 111 of the controller body 110, the treatment structure 20 is electrically connected to the battery 130 and control board 140 built into the controller body 110 via the cable 101.

[0019] In this embodiment, the treatment structure 20 and the cable 101 cannot be detached from each other, but it is also possible to configure the treatment structure 20 and the cable 101 to be detachable from each other. In addition, it is also possible to provide a power switch or the like on the treatment structure 20 itself.

[0020] In addition, in this embodiment, as shown in Figure 2, the treatment structure 20 is removably attached to the mask body 10, and by removing the treatment structure 20 from the mask body 10, the mask body 10 and the treatment structure 20 can be cared for separately.

[0021] The mask body 10 can be made of a material such as silicone rubber and has flexibility. In this manner, in the present embodiment, the mask body 10 is made flexible so that it can be deformed to follow the shape of the face when worn on the face. In this manner, when the mask body 10 is worn on the face, the inner surface 10a of the mask body 10 (the surface facing the face when in use) can be more reliably attached to the face.

[0022] In this embodiment, a pair of left and right first exposure holes 11 are formed in the upper part of the mask body 10, and one second exposure hole 12 is formed in the center in the left-right direction below the pair of left and right first exposure holes 11. And one third exposure hole 13 is formed below the second exposure hole 12.

[0023] By forming such exposure holes in the mask body 10, when the mask body 10 is worn on the face, the eyes are exposed through the first exposure hole 11, the nostrils are exposed through the second exposure hole 12, and the mouth is exposed through the third exposure hole 13.

[0024] In addition, the portion located above the first exposure hole 11 of the mask body 10 constitutes a forehead covering portion 15 that can come into contact with the forehead when worn, and the portion located below the third exposure hole 13 constitutes a chin covering portion 16 that can come into contact with the chin when worn.

[0025] In this embodiment, the second exposure hole 12 is formed to open obliquely downward, and the portion located above the second exposure hole 12 serves as a nose covering portion 17 that can come into contact with the nose when worn. The portions located below the first exposure hole 11 and on both the left and right sides of the nose covering portion 17, the second exposure hole 12, the third exposure hole 13, and the chin covering portion 16 serve as cheek covering portions 14 that can come into contact with the cheeks when worn. A pair of cheek covering portions 14 are formed on both the left and right sides of the mask body 10.

[0026] In this manner, in this embodiment, when the facial beauty device 1 is in use, almost all areas of the face except for the eyes, nostrils, and mouth are covered by the mask body 10.

[0027] Furthermore, in this embodiment, a storage section 141 for storing and holding the treatment structure 20 is provided in a portion that becomes the cheek covering section 14 on the inner surface (the surface facing the face during use) 10a of the mask body 10. In this manner, in this embodiment, a pair of treatment structures 20 is provided, and the pair of treatment structures 20 are attached to the cheek covering sections 14 on both the left and right sides of the inner surface 10a of the mask body 10. Also, a groove section 142 communicating with the storage section 141 is formed in each of the cheek covering sections 14, and the cable 101 connected to the treatment structure 20 is stored and held in this groove section 142.

[0028] A belt 18 is connected to the mask body 10, and the mask body 10 is attached to the face by wrapping the belt 18 around the head.

[0029] In this embodiment, the belt 18 includes a first band 181 connected to one of the left and right sides of the mask body 10, and a second band 182 connected to the other of the left and right sides of the mask body 10.

[0030] In this embodiment, a first hook-and-loop fastener 1811 and a second hook-and-loop fastener 1821 are formed on the tip side of first strap-shaped body 181 and the tip side of second strap-shaped body 182, respectively. When mask body 10 is to be worn on the face, first strap-shaped body 181 and second strap-shaped body 182 are wrapped around the head from the sides, and first hook-and-loop fastener 1811 and second hook-and-loop fastener 1821 are engaged on the back of the head. In this way, mask body 10 can be worn on the face while applying a desired pulling force to mask body 10.

[0031] In this manner, in this embodiment, the mask body 10 can be worn on the face by operating a set of belts 18 provided on the mask body 10. Also, in this embodiment, the mask body 10 can be worn on the face simply by engaging the first hook-and-loop fastener 1811 with the second hook-and-loop fastener 1821. In other words, the mask body 10 can be worn on the face with a single simple operation.

[0032] However, if the mask body 10 is configured to be worn on the face using only one set of belts 18 provided on the left and right sides, there is a risk that the mask body 10 may shift in position in the vertical direction.

[0033] In particular, in the facial beauty device 1 according to the present embodiment, since the pair of treatment structures 20 are attached to the mask body 10, there is a risk that the weight of the treatment structures 20 will cause the mask body 10 to shift downward.

[0034] Therefore, in the present embodiment, the mask body 10 can be more easily attached to the face, and the mask body 10 is prevented from shifting downward.

[0035] Specifically, the facial beauty device 1 is provided with a position shift suppression portion that can contact the unevenness of the face from above and suppress downward position shift of the mask body 10.

[0036] In this embodiment, the forehead covering portion 15 functions as a position shift prevention portion.

[0037] Specifically, the shape of the forehead covering part 15 of the mask body 10 corresponds to the shape of the forehead in a natural state (when the mask body 10 is not attached to the face). That is, as shown in Fig. 8, the forehead covering part 15 has a curved part 151 that protrudes forward, so that the forehead covering part 15 can be closely attached to a forehead that has a convex shape that protrudes forward.

[0038] This curved portion 151 is formed with an apex 151a that protrudes furthest forward in the center in the vertical direction, and the curved portion 151 has an upper curved portion 1511 located above the apex 151a, and a lower curved portion 1512 located below the apex 151a.

[0039] The forehead covering portion 15 is configured so that the creeping distance in the left-right direction becomes shorter from the center toward the upper end in the vertical direction. Specifically, the shape of the upper curved portion 1511 is configured so that the creeping distance in the left-right direction becomes shorter from the apex 151a toward the upper end 1511a. That is, as shown in FIG. 1, the creeping distance in the left-right direction of the upper curved portion 1511 is longest at the apex 151a, and shortest at the upper end 1511a, i.e., creeping distance L1 in the left-right direction.

[0040] In this way, when the mask body 10 is placed on the face, the upper curved portion 1511 comes into contact with the upper part of the forehead, which is one of the facial irregularities, from above, and the pulling force applied to the upper curved portion 1511 at this time increases with increasing upward force. By placing the mask body 10 on the face with a relatively large pulling force applied to the upper end portion 1511a, the upper curved portion 1511 suppresses downward displacement of the mask body 10.

[0041] In this embodiment, when the mask body 10 is attached to the face, the top portion 151a is made to contact the convex part of the forehead of the face to be treated. Therefore, the facial beauty device 1 according to this embodiment is a mask-type facial beauty device provided with a structure (treatment structure 20) for performing treatment on the face, and has a structure in which the creeping distance in the left-right direction from the convex part of the forehead of the face to be treated to the upper end of the mask is short.

[0042] In this embodiment, the shape of the chin covering part 16 is made to protrude downward and forward so that it can fit the lower jaw. This makes it possible to form a space 16a for accommodating the lower jaw on the inner surface 10a side of the mask body 10. Furthermore, in this embodiment, the size of the chin covering part 16 is made slightly smaller than the size of a general lower jaw, so that the chin covering part 16 can fit the lower jaw better when the mask body 10 is worn on the face.

[0043] In this embodiment, the portion of the mask body 10 that comes into contact with the chin is made more flexible than the portions of the mask body 10 that come into contact with other parts of the face. That is, the chin covering portion 16 is made more flexible than the other portions of the mask body 10. This improves the fit around the chin when the mask body 10 is worn, and further improves the usability of the facial beauty device 1.

[0044] In this embodiment, as described above, the mask body 10 is formed using a material such as silicone rubber, so that the entire mask body 10 is made of an elastic body. Therefore, the chin covering part 16, which is the part of the mask body 10 that comes into contact with the chin, is also made of an elastic body. In this manner, in this embodiment, the chin covering part 16 is made of an elastic body, so that the chin covering part 16 has flexibility. Such an elastic body can be formed using, for example, rubber, carbon nanotubes, springs, viscoelastic substances, and the like.

[0045] Furthermore, in this embodiment, the thickness of the mask body 10 at the portion where the chin comes into contact is reduced, thereby improving the flexibility of the portion of the mask body 10 where the chin comes into contact. Specifically, the chin covering portion 16 has a thin portion 162 that is thinner than other portions of the mask body 10. In this embodiment, the entire chin covering portion 16 is made to be the thin portion 162. This improves the flexibility of the chin covering portion 16.

[0046] In this embodiment, the chin covering part 16, which is the part of the mask body 10 that comes into contact with the chin, is configured to have a shape that turns outward from the mask. Specifically, as shown in Fig. 8, the lower end of the chin covering part 16 is formed with a turned-out part 161 that is turned outward, and the rounded part of the turned-out part 161 is configured as a skin contact surface 161a that can come into contact with the skin.

[0047] This prevents the edge portion from touching the chin when the mask body 10 is worn, improving the feel of the mask body 10 against the skin when worn.

[0048] Next, a description will be given of a specific configuration of the treatment structure 20. In this embodiment, the pair of left and right treatment structures 20 have the same structure.

[0049] The treatment structure 20 includes a flexible silicone pad 50, and one electrode portion 40 and one heater 60 are held on the silicone pad 50.

[0050] 9, the silicon pad 50 is provided with a substantially disk-shaped electrode holding wall 510 that is disposed in the center and extends along the inner surface 10a of the mask body 10 when attached to the mask body 10. The electrode portion 40 is attached to the electrode holding wall 510.

[0051] The silicon pad 50 also includes a heater holding wall 530 that is disposed radially outward of the electrode holding wall 510 so as to surround the outer periphery of the electrode holding wall 510 and that holds the heater 60. The silicon pad 50 also includes a connecting wall 520 that connects the electrode holding wall 510 and the heater holding wall 530. The connecting wall 520 is substantially U-shaped and can be deformed to follow the relative movement of the electrode unit 40.

[0052] The heater holding wall 530 includes a covering wall 531 that extends along the inner surface 10a of the mask body 10 when attached to the mask body 10 and covers the heater 60 from the inside (skin side).

[0053] The heater holding wall 530 is connected to the inner peripheral end of the covering wall 531 and includes an inner peripheral folded wall 532 that is folded back radially outward from the outer side in the thickness direction (the side opposite to the skin side). The heater holding wall 530 is connected to the outer peripheral end of the covering wall 531 and includes an outer peripheral folded wall 533 that is folded back radially inward from the outer side in the thickness direction (the side opposite to the skin side). The heater 60 is held on the silicon pad 50 by the covering wall 531, the inner peripheral folded wall 532, and the outer peripheral folded wall 533.

[0054] In this manner, in this embodiment, the surface of the covering wall 531 is exposed when attached to the mask body 10, and the exposed surface of the covering wall 531 is the skin contact surface 531a that can be brought into contact with the skin. By bringing the skin contact surface 531a into contact with the skin, the heat of the heater 60 is transferred to the skin from the skin contact surface (skin side surface) 531a. Therefore, in this embodiment, the part of the treatment structure 20 where the heater 60 is arranged is the heating section 30 that functions as a heat generating body section, and the skin contact surface 531a is the skin side surface of the heating section 30.

[0055] Furthermore, in this embodiment, the outer circumferential folded wall 533 is connected to the outer circumferential end of the covering wall 531 and includes an inner horizontal wall 5331 that extends along the inner surface 10a of the mask body 10 when attached to the mask body 10. The outer circumferential folded wall 533 is connected to the inner circumferential end of the inner horizontal wall 5331 and includes an inclined wall 5332 that inclines outward in the thickness direction as it moves radially inward. The outer circumferential folded wall 533 is connected to the inner circumferential end of the inclined wall 5332 and includes a vertical wall 5333 that extends in the thickness direction. The outer circumferential folded wall 533 is connected to the outer end of the vertical wall 5333 in the thickness direction and includes an outer horizontal wall 5334 that extends along the inner surface 10a of the mask body 10 when attached to the mask body 10.

[0056] The silicon pad 50 having such a structure is attached to a housing 70 having rigidity.

[0057] In this embodiment, the housing 70 includes a main body 710 disposed on the outside in the thickness direction, and a pressing plate 720 for attaching the silicone pad 50 to the housing 70. The main body 710 and the pressing plate 720 sandwich the outer lateral wall 5334, thereby allowing the silicone pad 50 to be attached to the housing 70. The main body 710 and the pressing plate 720 are fixed together with screws (not shown).

[0058] Furthermore, in this embodiment, an engagement protrusion 721 is provided on the outer periphery of the pressing plate 720, and this engagement protrusion 721 is removably engaged with an engagement groove 141a formed in the storage section 141, so that the treatment structure 20 is removably attached to the mask body 10.

[0059] The electrode section 40 includes an electrode body 410 and an electrode holding section 420 that holds the electrode body 410. The electrode body 410 can be formed using, for example, a titanium alloy, and includes a plate-shaped electrode 411 and a platform electrode 412 that is disposed inside the plate-shaped electrode 411.

[0060] The plate electrode 411 is fixed to the electrode holding portion 420 via an O-ring 440, and the gap between the plate electrode 411 and the electrode holding portion 420 is sealed by the O-ring 440. On the other hand, the pedestal electrode 412 is fixed to an attachment rib 421 provided on the electrode holding portion 420. At this time, the O-ring 430 seals the gap between the pedestal electrode 412 and the electrode holding portion 420.

[0061] The electrode section 40 also includes an attachment plate 460, and the electrode holding wall 510 of the silicon pad 50 is sandwiched between the attachment plate 460 and the electrode holding section 420, thereby allowing the electrode section 40 to be attached to the silicon pad 50. The attachment plate 460 and the electrode holding section 420 are fixed together with screws (not shown).

[0062] In the present embodiment, the attachment plate 460 and the electrode holding portion 420 have rigidity, and the electrode portion 40 itself is also configured to have rigidity.

[0063] When the electrode body 410 is attached to the mask body 10, the surface of the electrode body 410 (the plate electrode 411 and the platform electrode 412) is exposed, and the exposed surface of the electrode body 410 is the skin contact surface 410a that can be brought into contact with the skin. By bringing the skin contact surface 410a into contact with the skin, an electric current can be passed through the skin. Therefore, in this embodiment, the skin contact surface 410a of the treatment structure 20 is the surface of the electrode section 40 on the skin side.

[0064] In this manner, in the present embodiment, with the treatment structure 20 attached to the mask body 10, the heating section 30 is provided on the mask body 10 in a state where it does not overlap with the electrode section 40 when viewed along the thickness direction of the mask body 10. This allows the facial beauty device 1 to be made thinner and lighter.

[0065] Furthermore, in this embodiment, the heating unit 30 is provided on the mask body 10 in a state in which it surrounds the periphery of the electrode unit 40. This allows the user to feel warmth not only in the area where the heating unit 30 is located, but also in the area where the electrode unit 40 is present, when using the facial beauty device 1. In other words, by surrounding the periphery of the electrode unit 40 with the heating unit 30, it is possible to feel warmth over a wider area by heating a relatively narrow area, and it is possible to efficiently transmit the warmth to the skin using a relatively small amount of energy.

[0066] In this embodiment, at least one of the skin contact surface (skin side surface) 531a of the heating unit 30 and the skin contact surface (skin side surface) 410a of the electrode unit 40 is flexible. Such a configuration can be formed, for example, by making the electrode unit 40 or the heating unit (heat generating unit) 30 a flexible structure and making it have a structure that curves according to the curved surface of the face shape. By making at least one of the surfaces flexible, it is possible to more reliably make the skin contact surface (skin side surface) 531a of the heating unit 30 or the skin contact surface (skin side surface) 410a of the electrode unit 40 adhere to the skin when the facial beauty device 1 is used. In this way, it is possible to improve the comfort of the user during treatment and improve the penetration performance in the transdermal penetration treatment, for example.

[0067] In this embodiment, the skin contact surface (skin side surface) 531a of the heating part 30 is made flexible.

[0068] Specifically, a flexible sheet heater 620 is attached to a flexible sheet-like heater base 610 to form a flexible heater 60. This flexible heater 60 is then held by a heater holding wall 530 of a flexible silicone pad 50 to form the heating unit 30. In this way, the skin contact surface (skin side surface) 531a of the heating unit 30 is made flexible.

[0069] In this manner, in this embodiment, the heating section (heat generating section) 30 is configured with a flexible structure, and has a structure that curves to fit the curved surface of the face shape.

[0070] Furthermore, in this embodiment, at least one of the heating unit 30 and the electrode unit 40 is provided on the mask body 10 in a state in which it can move (float) relative to the thickness direction of the mask body 10. This configuration can be formed, for example, by floating the electrode unit 40 or the heating unit (heat generating unit) 30 with a structural spring, so as to have a structure that fits the curved surface of the face shape. By floating at least one of them, the heating unit 30 and the electrode unit 40 can be more reliably brought into contact with the skin when the facial beauty device 1 is used.

[0071] In this embodiment, both the heating section 30 and the electrode section 40 are provided on the mask body 10 in a state in which they can move (float) relatively in the thickness direction of the mask body 10. At this time, the heating section 30 and the electrode section 40 are allowed to move (float) relatively in the thickness direction of the mask body 10 separately. This allows the float amount (distance of relative movement) and float load (contact pressure on the skin) of the heating section 30 and the float amount (distance of relative movement) and float load (contact pressure on the skin) of the electrode section 40 to be set to suitable values. Thus, in this embodiment, the electrode section 40 and the heating section (heat generating section) 30 are separate structures, and each has an individual float structure, float amount, or float load to fit the face.

[0072] Specifically, the outer circumferential folded wall 533 of the silicone pad 50 is provided with an inclined wall 5332, and the outer side wall 5334 of the outer circumferential folded wall 533 is sandwiched between the main body 710 and the pressing plate 720, thereby attaching the silicone pad 50 to the housing 70. In this way, a space S1 that allows the heating unit 30 to float is formed between the inner side wall 5331 and the pressing plate 720. The outer circumferential folded wall 533 functions as a leaf spring, thereby forming a floating structure for the heating unit 30.

[0073] At this time, the distance between the inner side wall 5331 and the pressing plate 720 is the float amount (the distance of relative movement) of the heating unit 30. In this embodiment, the float amount (the distance of relative movement) of the heating unit 30 is set to about 2 mm.

[0074] In this embodiment, the electrode section 40 is held by the electrode holding wall 510 of the silicon pad 50. At this time, a space S2 that allows the electrode section 40 to float is formed between the mounting plate 460 and the main body section 710. A contact pressure spring 450 is provided at the outer end of the electrode section 40 in the thickness direction, and a spring receiver 712 that receives the contact pressure spring 450 is formed at the inner end of the main body section 710 in the thickness direction. In this way, a float structure of the electrode section 40 is formed. Note that the main body section 710 is provided with an air hole 711 for releasing air in the space S2 to the outside, and when the electrode section 40 is floated, the air in the space S2 is discharged to the outside from the air hole 711. In this way, the electrode section 40 can be floated more smoothly. Furthermore, in this embodiment, the air hole 711 is blocked by a filter 730. This filter 730 has a function of passing air but not passing water. With this configuration, the electrode section 40 can be made to float more smoothly while ensuring the watertightness of the treatment structure 20.

[0075] In this embodiment, the distance between the attachment plate 460 and the main body portion 710 is the amount of float of the electrode portion 40 (the distance of relative movement).

[0076] Here, in this embodiment, when the mask body 10 is attached to the face, the electrode section 40 is made to come into contact with the skin before the heating section 30, so that the electrode section 40 can be more reliably brought into contact with the skin to allow a current to flow through the skin. That is, in this embodiment, in a natural state, the skin contact surface (skin side surface) 410a of the electrode section 40 is made to protrude inward in the thickness direction from the skin contact surface (skin side surface) 531a of the heating section 30. Therefore, in this embodiment, the float amount (distance of relative movement) of the electrode section 40 is made to be greater than the float amount (distance of relative movement) of the heating section 30. Specifically, the float amount (distance of relative movement) of the electrode section 40 is made to be about 3.5 mm.

[0077] The facial beauty device 1 having such a configuration can be used, for example, in the following manner.

[0078] First, the connector of the cap 120 is fitted into the connector 111 of the controller body 110 so that the treatment structure 20 is electrically connected to the battery 130 and the control board 140 built into the controller body 110 via the cable 101. Next, the pair of treatment structures 20 are attached to the mask body 10. In this way, the facial beauty device 1 shown in FIG. 1 is obtained. Thereafter, with the inner surface 10a of the mask body 10 in contact with the face moistened with lotion or the like, the first belt-shaped body 181 and the second belt-shaped body 182 are wrapped around the head while being pulled from the side to the rear, and the first hook-and-loop fastener 1811 and the second hook-and-loop fastener 1821 are engaged at the back of the head. In this way, the mask body 10 is attached to the face while applying a desired pulling force to the mask body 10.

[0079] Then, the switch button 150 of the controller 100 is operated to turn on the power. Then, a potential difference is generated between the pair of electrode parts 40, and a current (weak current) flows from one electrode part 40 to the other electrode part 40. Also, the heater 60 is heated, and heat is transferred from the heating part 30 to the skin. At this time, since the face is moistened with lotion or the like, a weak current flows over the entire face via the lotion or the like.

[0080] By warming the skin with the heating section 30 and passing a current (weak current) through the skin with the electrode section 40, the beauty ingredients contained in the lotion or the like are more effectively absorbed into the skin.

[0081] Furthermore, by using a mask-type facial beauty device 1 as in this embodiment, it is possible to prevent moisture from evaporating from the skin, so that electric current can be passed through the skin more reliably, and beauty ingredients can be more effectively absorbed into the skin.

[0082] In this way, the facial beauty device 1 of this embodiment is a mask-type facial beauty device that has an electrode unit 40 with a pair of electrodes capable of treating the face, a heating unit (heating element unit) 30 arranged to surround the electrodes, a battery (electricity supply unit) 130 that supplies power (electricity) to the electrode unit 40 and the heating unit (heating element unit) 30, and a control board (control unit) 140 that controls the electrode unit 40 and the heating unit (heating element unit) 30, and uses the electrode unit 40 and the heating unit (heating element unit) 30 to treat the face while heating it.

[0083] At this time, it is preferable that the control board (control unit) 140 controls the temperature of the heating unit (heat generating unit) 30 during facial treatment so that the temperature becomes such that the polymer can easily permeate.

[0084] For example, if the temperature of the heating section (heat generating section) 30 is maintained in the range of 39.0°C to 41.8°C during facial treatment, the temperature of the face can be set to approximately 40.0°C to 43.0°C, making it easier for the beauty ingredients to penetrate the skin in polymer form.

[0085] Furthermore, the control board (control unit) 140 can also control the electrode unit 40 so that the output level or operation timing during facial treatment facilitates polymer permeation.

[0086] For example, the effective value (output level) of the maximum current applied to the electrode portion 40 can be set to 0.25 mArms. This makes it easier for the beauty ingredient to penetrate the skin in a polymeric form.

[0087] It is also possible to facilitate polymer penetration of the beauty ingredient into the skin by intermittently passing a current through the electrode unit 40. For example, it is possible to output a rectangular pulse wave with a frequency of 3 kHz, a duty ratio of 50%, and a polarity inversion period (a period during which the polarity of the left and right electrodes is switched between + / -) of 9 seconds to the electrode unit 40. This makes it possible to facilitate polymer penetration of the beauty ingredient into the skin.

[0088] [Actions and Effects] The characteristic configuration of the facial beauty device shown in the above embodiment and the effects obtained thereby will be described below.

[0089] (1) The facial beauty device shown in the above embodiment includes a mask body 10 that can be worn on the face, and a treatment structure 20 that is provided on the mask body 10 and can perform skin treatment. Furthermore, the facial beauty device 1 includes a pair of belts 18 that are connected to the left and right sides of the mask body 10 and can wear the mask body 10 on the face, and a position shift suppression unit that can contact the unevenness of the face from above and suppress downward position shift of the mask body 10.

[0090] In this way, in the facial beauty device 1 shown in this embodiment, the mask body 10 is attached to the face by a set of belts 18. Therefore, the mask body can be attached to the face with a single operation, and the mask body can be attached to the face more easily. Furthermore, the facial beauty device 1 shown in this embodiment is equipped with a position shift suppression part that can contact the unevenness of the face from above and suppress the downward position shift of the mask body 10. Therefore, it is possible to suppress the mask body 10 from shifting downward.

[0091] In this way, the facial beauty device 1 shown in the above embodiment makes it easier to attach the mask body 10 to the face, and also makes it possible to prevent the mask body 10 from shifting downward.

[0092] (2) The mask body 10 may have a forehead covering portion 15 that can come into contact with the forehead. The forehead covering portion 15 may be configured so that the creeping distance in the left-right direction becomes shorter from the center in the up-down direction toward the upper end, and the displacement suppression portion may have the forehead covering portion 15.

[0093] This makes it possible to prevent the mask body 10 from shifting downward with a simpler configuration.

[0094] (3) The mask body 10 may have a chin covering portion 16 that can come into contact with the chin, and the chin covering portion 16 may be made more flexible than other portions of the mask body 10.

[0095] This makes it possible to improve the fit around the chin when the mask body 10 is worn, and thus makes it possible to further improve the usability of the facial beauty device 1.

[0096] (4) The chin covering portion 16 may also have a thin portion 162 that is thinner than other portions of the mask body 10.

[0097] This makes it easier to manufacture the chin covering portion 16 which is more flexible than the other portions of the mask body 10.

[0098] (5) In addition, a bent portion 161 is formed at the lower end of the chin covering portion 16 with the tip facing outward, and the rounded portion of the bent portion 161 may be made to serve as a skin contact surface 161a that can come into contact with the skin.

[0099] In this way, it is possible to prevent the edge portion from touching the chin when wearing the mask body 10. As a result, it is possible to improve the feel of the mask body 10 against the skin when worn.

[0100] [others] The facial beauty device according to the present disclosure has been described above, but it is not limited to this description, and it will be obvious to those skilled in the art that various modifications and improvements are possible.

[0101] For example, in the above embodiment, the facial beauty device 1 is exemplified in which the treatment structure 20 heats and energizes the skin, but it is also possible to make the facial beauty device 1 equipped with a treatment structure capable of obtaining other treatment effects. Note that other treatment effects include, for example, hyperthermia, low-frequency treatment, iontophoresis, microcurrent (weak current therapy), EMS (Electrical Muscle Stimulation), phototherapy, ultrasonic treatment, etc. It is also possible to make the treatment structure capable of exerting two or more of these treatment effects.

[0102] Also, different types of treatment structures may be attached to the mask body.

[0103] In the above embodiment, the facial beauty device 1 is exemplified in which the forehead covering part 15 functions as a position shift suppression part, but the present invention is not limited to this. For example, the mask body 10 may be prevented from shifting downward by a structure in which the nose covering part is provided with a nose pad, a structure in which a hook is provided between the nose and the upper lip, a structure in which holes are drilled in the belt 18 so that the mask body 10 can be hooked on the ears, or the like. In addition, it is also possible to use a structure in which these are combined in any desired manner.

[0104] In the above embodiment, the facial beauty device 1 is exemplified in which the chin covering part 16 is provided with flexibility by providing the thin part 162 in the chin covering part 16, but the present invention is not limited to this. For example, the chin covering part 16 can be made flexible by forming the chin covering part 16 from a material that is more flexible than other parts.

[0105] In addition, the specifications of the mask body, treatment structure, and other details (shape, size, layout, etc.) can be changed as appropriate. [Industrial Applicability]

[0106] As described above, the facial beauty device according to the present disclosure allows the mask body to be more easily attached to the face and prevents the mask body from shifting downward, and therefore can be used in a variety of facial beauty devices, including those for home and commercial use.
