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

[0011] 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 of this embodiment comprises a mask body 10 that can be attached to the face, and a treatment structure 20 that is attached to 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 it, so that the treatment structure 20 performs a treatment on the skin.

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

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

[0016] Here, the controller main body 110 has built-in a battery 130 as a power supply unit that supplies power (electricity) to the treatment structure 20 (the electrode unit 40 and the heating unit 30, which will be described later), and a control board 140 as a control unit that controls the electrode unit 40 and the heating unit 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 has a switch button 150 that controls the power on / off, the output level and operation timing of the electrode unit 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 main body 110. One end of a cable 101 electrically connected to the treatment structure 20 is attached to this connector (not shown). In other words, the cable 101 is electrically connected to a connector (not shown) of the cap 120.

[0018] Then, by fitting the connector of the cap 120 into the connector 111 of the controller main body 110, the treatment structure 20 is electrically connected to the battery 130 and control board 140 built into the controller main 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. Also, it is 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 detachably 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 is flexible. In this embodiment, the mask body 10 is flexible so that it can deform to conform to the shape of the face when worn on the face. This allows the inner surface 10a of the mask body 10 (the surface facing the face during use) to be more reliably fitted to the face when worn on 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 part of the mask body 10 located above the first exposure hole 11 is a forehead covering part 15 that can come into contact with the forehead when worn, and the part located below the third exposure hole 13 is a chin covering part 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 is 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, the mask body 10 covers almost all areas of the face except for the eyes, nostrils, and mouth.

[0027] Furthermore, in this embodiment, a storage section 141 that stores and holds the treatment structure 20 is provided in a region that will become the cheek covering section 14 on the inner surface 10a (the surface that faces the face during use) of the mask main body 10. In this way, 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 main body 10, respectively. Also, a groove section 142 that communicates 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 comprises 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, first and second hook-and-loop fasteners 1811 and 1821 are formed on the tip of first strap 181 and the tip of second strap 182, respectively. When wearing mask body 10 on the face, first strap 181 and second strap 182 are wrapped around the head from the sides, and first and second hook-and-loop fasteners 1811 and 1821 are engaged at the back of the head. This allows mask body 10 to be worn on the face while applying a desired pulling force to mask body 10.

[0031] As described above, 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 this embodiment, since the pair of treatment structures 20 are attached to the mask body 10, the weight of the treatment structures 20 may cause the mask body 10 to shift downward.

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

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

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

[0037] Specifically, the shape of the forehead covering part 15 of the mask body 10 is designed to correspond 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 fitted to a forehead that has a convex shape that protrudes forward.

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

[0039] The forehead covering portion 15 is configured so that the creeping distance in the left-right direction decreases 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 decreases 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 such that the creeping distance L1 at the apex 151a is the longest and the creeping distance L2 at the upper end 1511a is the shortest.

[0040] By doing so, when the mask body 10 is worn on the face, the upper curved portion 1511 comes into contact from above with the upper part of the forehead, which is one of the facial irregularities, and the pulling force applied to the upper curved portion 1511 at this time increases upward. Then, by wearing 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 prevents the mask body 10 from shifting downward.

[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) that performs treatment on the face, and has a structure that shortens the creeping distance in the left-right direction from the convex part of the forehead of the face to be treated to the top end of the mask.

[0042] In this embodiment, the shape of the chin covering part 16 is designed to protrude downward and forward so that it can fit the lower jaw. This allows a space 16a for accommodating the lower jaw to be formed on the inner surface 10a side of the mask body 10. Furthermore, in this embodiment, the size of the chin covering part 16 is slightly smaller than the size of a typical 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] Furthermore, in this embodiment, the portion of the mask body 10 that comes into contact with the chin is made more flexible than the portions 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 wearing the mask body 10, 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 material. Therefore, the chin covering portion 16, which is the portion of the mask body 10 that comes into contact with the chin, is also made of an elastic material. In this manner, in this embodiment, the chin covering portion 16 is made of an elastic material, thereby imparting flexibility to the chin covering portion 16. Such an elastic material can be formed using, for example, rubber, carbon nanotubes, springs, viscoelastic substances, etc.

[0045] Furthermore, in this embodiment, the thickness of the mask body 10 at the portion that comes into contact with the chin is reduced, thereby improving the flexibility of the portion of the mask body 10 that comes into contact with the chin. 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 have the thin portion 162. This improves the flexibility of the chin covering portion 16.

[0046] In this embodiment, chin covering portion 16, which is the portion of mask body 10 that comes into contact with the chin, has a shape that turns outward from the mask. Specifically, as shown in Fig. 8, chin covering portion 16 has a turned-out portion 161 at the lower end thereof that is bent so that the tip faces outward, and the rounded portion of turned-out portion 161 is made into skin contact surface 161a that can come into contact with the skin.

[0047] This prevents the edge portion from touching the chin when wearing the mask body 10, making it possible to make the mask body 10 feel more comfortable against the skin when worn.

[0048] Next, we will explain the 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 this silicone pad 50 holds one electrode portion 40 and one heater 60.

[0050] 9, the silicone 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 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 the skin side). The heater 60 is held on the silicone pad 50 by the covering wall 531, the inner peripheral folded wall 532, and the outer peripheral folded wall 533.

[0054] As described above, 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 serves as the skin contact surface 531a that can be brought into contact with the skin. By bringing this 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 portion of the treatment structure 20 where the heater 60 is arranged serves as the heating unit 30 that functions as a heat generating element, and the skin contact surface 531a serves as the skin-side surface of the heating unit 30.

[0055] Furthermore, in this embodiment, the outer peripheral folded wall 533 is connected to the outer peripheral 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 peripheral folded wall 533 is connected to the inner peripheral end of the inner horizontal wall 5331 and includes an inclined wall 5332 that slopes outward in the thickness direction as it extends radially inward. The outer peripheral folded wall 533 is connected to the inner peripheral end of the inclined wall 5332 and includes a vertical wall 5333 that extends in the thickness direction. The outer peripheral 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 presser plate 720 that attaches the silicone pad 50 to the housing 70. The main body 710 and the presser plate 720 sandwich the outer lateral wall 5334, thereby attaching the silicone pad 50 to the housing 70. The main body 710 and the presser 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 pressure plate 720, and by removably engaging this engagement protrusion 721 with an engagement groove 141a formed in the storage section 141, the treatment structure 20 can be removably attached to the mask body 10.

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

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

[0061] The electrode unit 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 unit 420, thereby allowing the electrode unit 40 to be attached to the silicon pad 50. The attachment plate 460 and the electrode holding unit 420 are fixed together with screws (not shown).

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

[0063] When attached to the mask body 10, the surfaces of the electrode body 410 (the plate-shaped electrode 411 and the platform-shaped electrode 412) are exposed, and the exposed surfaces of the electrode body 410 form the skin contact surface 410a that can be brought into contact with the skin. By bringing this skin contact surface 410a into contact with the skin, it is possible to pass a current 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 this embodiment, with the treatment structure 20 attached to the mask body 10, the heating unit 30 is provided on the mask body 10 in a state where it does not overlap with the electrode unit 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 makes it possible 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 small area, and it is possible to transmit warmth to the skin efficiently with a relatively small amount of energy.

[0066] In this embodiment, at least one of the skin-contacting surface (skin-side surface) 531a of the heating unit 30 and the skin-contacting surface (skin-side surface) 410a of the electrode unit 40 is flexible. This configuration can be achieved, for example, by configuring the electrode unit 40 or the heating unit (heat generating unit) 30 with a flexible structure that curves to fit the curves of the face. By providing flexibility to at least one of these surfaces, the skin-contacting surface (skin-side surface) 531a of the heating unit 30 or the skin-contacting surface (skin-side surface) 410a of the electrode unit 40 can be more reliably fitted to the skin during use of the facial beauty device 1. This can improve the user's comfort during treatment and improve penetration performance during 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. This gives flexibility to the skin contact surface (skin side surface) 531a of the heating unit 30.

[0069] As described above, in this embodiment, the heating section (heat generating section) 30 is made of a flexible structure, and has a structure that can bend 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 of the mask body 10. This configuration can be achieved, for example, by floating the electrode unit 40 or the heating unit (heat generating unit) 30 with a structural spring, thereby providing a structure that fits the curved surface of the face. By floating at least one of them, the heating unit 30 or the electrode unit 40 can be more reliably brought into contact with the skin when the facial beauty device 1 is in use.

[0071] In this embodiment, both the heating unit 30 and the electrode unit 40 are provided on the mask body 10 in a state in which they can move relatively (float) in the thickness direction of the mask body 10. At this time, the heating unit 30 and the electrode unit 40 are allowed to move relatively (float) separately in the thickness direction of the mask body 10. This allows the float amount (distance of relative movement) and float load (contact pressure on the skin) of the heating unit 30 and the float amount (distance of relative movement) and float load (contact pressure on the skin) of the electrode unit 40 to be set to appropriate values. Thus, in this embodiment, the electrode unit 40 and the heating unit (heat generating unit) 30 are separate structures, and each has its own 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 lateral 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 lateral 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 lateral wall 5331 and the pressing plate 720 is the floating amount (the distance of relative movement) of the heating unit 30. In this embodiment, the floating amount (the distance of relative movement) of the heating unit 30 is set to about 2 mm.

[0074] In this embodiment, the electrode unit 40 is held by the electrode holding wall 510 of the silicone pad 50. A space S2 that allows the electrode unit 40 to float is formed between the mounting plate 460 and the main body 710. A contact pressure spring 450 is provided at the outer end of the electrode unit 40 in the thickness direction, and a spring retainer 712 that supports the contact pressure spring 450 is formed at the inner end of the main body 710 in the thickness direction. This provides a floating structure for the electrode unit 40. The main body 710 is provided with an air hole 711 for venting air from the space S2. When the electrode unit 40 is floated, the air from the space S2 is discharged from the air hole 711. This allows the electrode unit 40 to float more smoothly. Furthermore, in this embodiment, the air hole 711 is blocked by a filter 730. This filter 730 allows air to pass through but not water. By adopting such a configuration, the watertightness of the treatment structure 20 is ensured, and the electrode section 40 can be made to float more smoothly.

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

[0076] In this embodiment, when the mask body 10 is worn on the face, the electrode unit 40 contacts the skin before the heating unit 30, so that the electrode unit 40 can be more reliably brought into contact with the skin and current can flow through the skin. That is, in this embodiment, in a natural state, the skin contact surface (skin-side surface) 410a of the electrode unit 40 protrudes inward in the thickness direction beyond the skin contact surface (skin-side surface) 531a of the heating unit 30. Therefore, in this embodiment, the float amount (distance of relative movement) of the electrode unit 40 is set to be greater than the float amount (distance of relative movement) of the heating unit 30. Specifically, the float amount (distance of relative movement) of the electrode unit 40 is set to be approximately 3.5 mm.

[0077] The facial beauty device 1 configured as above can be used, for example, as follows.

[0078] First, the connector of the cap 120 is fitted into the connector 111 of the controller main body 110, so that the treatment structure 20 is electrically connected to the battery 130 and control board 140 built into the controller main body 110 via the cable 101. Next, the pair of treatment structures 20 is attached to the mask main body 10. This completes the facial beauty device 1 shown in FIG. 1. Then, with the inner surface 10a of the mask main body 10 in contact with a face moistened with lotion or the like, the first strap 181 and the second strap 182 are wrapped around the head while being pulled from the sides 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 main body 10 is fitted to the face while applying a desired pulling force to the mask main body 10.

[0079] Then, the switch button 150 of the controller 100 is operated to turn on the power. This generates a potential difference between the pair of electrode units 40, causing a current (weak current) to flow from one electrode unit 40 to the other electrode unit 40. Furthermore, the heater 60 is heated, and heat is transferred from the heating unit 30 to the skin. At this time, since the face is moistened with lotion or the like, a weak current flows throughout the face via the lotion or the like.

[0080] The skin is warmed by the heating unit 30, and an electric current (weak current) is passed through the skin by the electrode unit 40, thereby allowing the beauty ingredients contained in the lotion or the like to penetrate the skin more effectively.

[0081] Furthermore, by using a mask-type facial beauty device 1 as in this embodiment, evaporation of moisture from the skin can be suppressed, allowing current to be passed through the skin more reliably and beauty ingredients to penetrate the skin more effectively.

[0082] As such, 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 that can be used to treat the face, a heating unit (heat generating unit) 30 that is arranged to surround the electrodes, a battery (electricity supply unit) 130 that supplies power (electricity) to the electrode unit 40 and the heating unit (heat generating unit) 30, and a control board (control unit) 140 that controls the electrode unit 40 and the heating unit (heat generating unit) 30, and uses the electrode unit 40 and the heating unit (heat generating 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 so that the temperature is such that the polymer can easily penetrate during the facial treatment.

[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 raised to approximately 40.0°C to 43.0°C, making it easier for the beauty ingredients to penetrate the skin in high 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 is such that the polymer can easily penetrate during facial treatment.

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

[0087] It is also possible to facilitate the penetration of cosmetic ingredients into the skin as polymers 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 reversal period (a period during which the polarity of the left and right electrodes changes between + and -) of 9 seconds to the electrode unit 40. This facilitates the penetration of cosmetic ingredients into the skin as polymers.

[0088] [Actions and Effects] The following describes the characteristic configuration of the facial beauty device shown in the above embodiment and the effects obtained thereby.

[0089] (1) The facial beauty device 1 shown in the above embodiment comprises a mask body 10 that can be worn on the face, a heating unit 30 that is provided on the mask body 10 and capable of warming the skin, and an electrode unit 40 that is provided on the mask body 10 and capable of passing an electric current through the skin. The heating unit 30 is provided on the mask body 10 in a manner that does not overlap with the electrode unit 40 when viewed along the thickness direction of the mask body 10.

[0090] In this way, in the facial beauty device 1 shown in this embodiment, the heating unit 30 and the electrode unit 40 are provided on the mask body 10 in a state where they do not overlap in the thickness direction of the mask body 10. In this way, there is no part on the mask body 10 where the heating unit 30 and the electrode unit 40 are stacked, so the facial beauty device 1 can be made thinner.

[0091] Therefore, with the facial beauty device 1 shown in the above embodiment, it is possible to make the device thinner.

[0092] Furthermore, by not stacking the heating section 30 and the electrode section 40 on the mask body 10, the weight of the heating section 30 and the electrode section 40 provided on the mask body 10 can be reduced, thereby making the beauty device 1 lighter.

[0093] (2) The heating unit 30 may be provided on the mask body 10 so as to surround the periphery of the electrode unit 40 .

[0094] This makes it possible 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 located. That is, it becomes possible to feel warmth in an area larger than the area to be heated. In other words, it becomes possible to limit the area where the heating unit 30 is located without impairing the feeling of warmth. In this way, by surrounding the electrode unit 40 with the heating unit 30, it becomes possible to feel warmth in a wider area by heating a relatively small area, and therefore it becomes possible to efficiently transmit warmth to the skin with relatively little energy.

[0095] (3) 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 may be flexible.

[0096] This allows 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 to be more reliably in close contact with the skin when using the facial beauty device 1. As a result, it is possible to improve the comfort of the user during treatment and improve the penetration performance in transdermal penetration treatment, for example.

[0097] (4) Furthermore, at least one of the heating unit 30 and the electrode unit 40 may be provided on the mask body 10 in a state in which it can move relatively in the thickness direction of the mask body 10 .

[0098] This allows the heating unit 30 and the electrode unit 40 to be in more reliable contact with the skin when using the facial beauty device 1. As a result, it is possible to improve the comfort of the user during treatment and improve the penetration performance of transdermal penetration treatment, for example.

[0099] (5) The heating unit 30 may be provided on the mask body 10 in a state in which it can move relatively in the thickness direction of the mask body 10. The electrode unit 40 may be provided on the mask body 10 separately from the heating unit 30 in a state in which it can move relatively in the thickness direction of the mask body 10.

[0100] This makes it possible to set appropriate values ​​for the float amount (distance of relative movement) and float load (contact pressure on the skin) of the heating unit 30 and the float amount (distance of relative movement) and float load (contact pressure on the skin) of the electrode unit 40. As a result, it becomes possible to improve the comfort of the user during treatment and improve the penetration performance in transdermal penetration treatment, for example.

[0101] (6) The device may further include a control board (control unit) 140 that controls the electrode unit 40 and the heating unit 30. The control board (control unit) 140 may then control the temperature of the heating unit 30 during facial treatment so that the temperature is such that the polymer can easily penetrate.

[0102] This will further improve the permeability during percutaneous permeation treatment.

[0103] (7) The device may further include a control board (control unit) 140 that controls the electrode unit 40 and the heating unit 30. The control board (control unit) 140 may then control the electrode unit 40 so that the output level or operation timing during facial treatment facilitates polymer penetration.

[0104] This also makes it possible to further improve the permeability during percutaneous permeation treatment.

[0105] [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.

[0106] For example, in the above embodiment, the facial beauty device 1 is exemplified as having the heating unit 30 and the electrode unit 40 detachably attached to the mask body 10, but this is not limited to this. For example, the facial beauty device 1 may be configured so that at least one of the heating unit 30 and the electrode unit 40 is attached to the mask body 10 in a non-detachable manner.

[0107] In addition, in the above embodiment, the heated region is a part of the area of ​​the mask body 10 where the electrode section 40 is not arranged, but it is also possible to use the entire area of ​​the mask body 10 where the electrode section 40 is not arranged as the heated region. This makes it possible to heat a wider range of skin, thereby further improving the effect of the skin treatment.

[0108] Furthermore, in the above embodiment, a facial beauty device 1 is exemplified in which both the heating unit 30 and the electrode unit 40 are made to float (move relative to each other), but it is also possible to make at least one of the heating unit 30 and the electrode unit 40 float (move relative to each other).

[0109] Furthermore, in the above embodiment, a facial beauty device 1 is exemplified in which the heating unit 30 and the electrode unit 40 are individually floated (moved relative to each other), but it is also possible to make the electrode unit 40 float (move relative to each other) in conjunction with the floating (movement relative to each other) of the heating unit 30.

[0110] In addition, in the above embodiment, the facial beauty device 1 is exemplified in which the electrode unit 40 has rigidity, but it is also possible to make the electrode unit 40 flexible by using, for example, conductive rubber, etc. In this case, the heating unit 30 may be flexible or rigid.

[0111] In the above embodiment, the facial beauty device 1 is exemplified as one in which the treatment structure 20 heats and energizes the skin, but it is also possible to configure the facial beauty device 1 to have a treatment structure that can achieve other treatment effects. Examples of other treatment effects include hyperthermia, low-frequency treatment, iontophoresis, microcurrent (weak current therapy), EMS (Electrical Muscle Stimulation), phototherapy, and ultrasonic treatment. It is also possible to configure a treatment structure that can achieve two or more of these treatment effects.

[0112] Also, different types of treatment structures may be attached to the mask body.

[0113] In addition, the specifications of the heating unit, electrode unit, and other details (shape, size, layout, etc.) can be changed as appropriate. [Industrial Applicability]

[0114] As described above, the facial beauty device according to the present disclosure can be made thinner, and therefore can be used in a variety of facial beauty devices, including those for home and commercial use. [Explanation of symbols]
