[0018] The following detailed description of the embodiments is provided with reference to the accompanying drawings. However, unnecessary detailed descriptions are sometimes omitted. For example, detailed descriptions of well-known matters or repeated descriptions of substantially the same structures are sometimes omitted. In addition, the accompanying drawings and the following descriptions 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.

[0019] Figure 1 It is a perspective view of the cosmetics device 1 which concerns on one embodiment. Figure 2 This is a plan view of the beauty device 1 when the mask body 10 is seen from the side worn on the face of the user. Figure 3This is an exploded view of the cosmetic device 1 when the mask body 10 is viewed from the side worn on the face of the user.

[0020] The beauty device 1 is a device that provides beauty effects by passing an electric current through the skin of the face as electrical stimulation, in which at least a portion of the beauty device 1 is worn on the face of the user. In addition, a beauty device that is worn on the face of the user, such as the beauty device 1, is sometimes referred to as a wearable beauty device or a beauty mask.

[0021] The beauty device 1 includes a mask body 10, a treatment structure 20, and a controller 30. Hereinafter, the top and bottom of the mask body 10 correspond to the upper side or the lower side in the plumb direction, based on the state in which the user of the beauty device 1 is facing straight ahead in a standing position or a sitting position. In addition, the left and right sides of the mask body 10 correspond to the left cheek side or the right cheek side of the user's face.

[0022] The mask body 10 is worn on the user's face when the user uses the beauty device 1. The material of the mask body 10 is an elastic material such as silicone rubber. Therefore, the mask body 10 is an elastic body with softness as a whole. When worn on the face, its inner surface 10a deforms to follow the shape of the face, thereby fitting closely to the face. The inner surface 10a is the side of the mask body 10 facing the face when in use. In addition, in this embodiment, the mask body 10 has a shape that can cover almost all areas of the face except the eyes, nostrils, and mouth.

[0023] First, the mask body 10 has a first exposure hole 11, a second exposure hole 12, and a third exposure hole 13 as hole portions, wherein the first exposure hole 11 is a pair of left and right holes. The first exposure hole 11 is formed at the upper portion of the mask body 10, so that the user's eyes are exposed to the outside when the mask body 10 is worn on the face. The second exposure hole 12 is formed below the first exposure hole 11 of the mask body 10, so that the user's nostrils are exposed to the outside when the mask body 10 is worn on the face. The third exposure hole 13 is formed below the second exposure hole 12 of the mask body 10, so that the user's mouth is exposed to the outside when the mask body 10 is worn on the face.

[0024] In addition, the mask body 10 has a cheek cover portion 14, a forehead cover portion 15, a chin cover portion 16, and a nose cover portion 17 as a cover portion covering the face. First, the forehead cover portion 15 is located above the first exposure hole 11 of the mask body 10, and contacts the forehead of the user when the mask body 10 is worn on the face. The chin cover portion 16 is located below the third exposure hole 13 of the mask body 10, and contacts the chin of the user when the mask body 10 is worn on the face. The nose cover portion 17 is located above the second exposure hole 12 in the mask body 10 so that the second exposure hole 12 is inclined outward and opens downward, and contacts the nose of the user when the mask body 10 is worn on the face. Moreover, there is one cheek covering part 14 below the first exposure hole 11 and on the left and right sides of the nose covering part 17, the second exposure hole 12, the third exposure hole 13 and the chin covering part 16, and faces one of the left and right cheeks of the user when the mask body 10 is worn on the face.

[0025] In addition, the mask body 10 has a receiving portion 14a for receiving and holding the treatment structure 20 at a portion of the inner surface 10a that becomes the cheek cover portion 14. The receiving portion 14a is provided at each of the cheek cover portions 14 on the left and right sides of the mask body 10. A groove portion 14b communicating with the receiving portion 14a may also be formed in the mask body 10. The groove portion 14b is used to receive a portion of the cable 33 connected to the treatment structure 20.

[0026] Furthermore, the mask body 10 has a belt 18 that is wound around the head to maintain the wearing position when worn on the face. The belt 18 includes: a first belt-shaped body 18a, which is connected to one of the left and right sides of the mask body 10; and a second belt-shaped body 18b, which is connected to the other of the left and right sides of the mask body 10. The first belt-shaped body 18a has a first surface connector 18c on the front end side. On the other hand, the second belt-shaped body 18b has a second surface connector 18d on the front end side. When the user wears the mask body 10 on the face, the first belt-shaped body 18a and the second belt-shaped body 18b are wound around the head from the side, and the first surface connector 18c and the second surface connector 18d are connected on the back of the head. As a result, the belt 18 can be applied to the mask body 10 while allowing the mask body 10 to be worn on the face.

[0027] The treatment structure 20 is operated by being supplied with power, thereby performing treatment on the user's skin. In the present embodiment, there are two treatment structures 20. The first treatment structure 20a on one side is mounted on the receiving portion 14a provided on the left cheek cover 14. The second treatment structure 20b on the other side is mounted on the receiving portion 14a provided on the right cheek cover 14. The first treatment structure 20a and the second treatment structure 20b have the same structure and are symmetrical to each other.

[0028] The treatment structure 20 is detachable from the mask body 10. The user can perform maintenance on the mask body 10 and the treatment structure 20 separately by removing the treatment structure 20 from the storage portion 14a. However, the treatment structure 20 may be provided integrally with the mask body 10.

[0029] The treatment structure 20 includes an electrode group 22, a silicon gasket 23, and a housing 24, wherein the electrode group 22 includes two or more electrodes 21. Hereinafter, the electrode group 22 included in the first treatment structure 20a is referred to as a first electrode group 22a, and the electrode group 22 included in the second treatment structure 20b is referred to as a second electrode group 22b.

[0030] As an example, the electrode group 22 includes four electrodes 21, namely, a first electrode 21a, a second electrode 21b, a third electrode 21c, and a fourth electrode 21d. The electrode 21 is made of, for example, a titanium alloy and has a so-called button-shaped shape including a flat portion that contacts the user's skin. In addition, in the present embodiment, the planar shape of the electrode 21 is circular, but may be other shapes.

[0031] Each electrode 21 can be set to a positive electrode or a negative electrode, that is, GND. When at least one electrode 21 is set to a positive electrode and at least one electrode 21 other than the positive electrode is set to a negative electrode, a potential difference is generated between the electrodes 21. Then, by energizing the electrodes 21 while the electrode group 22 is in contact with the skin, an alternating current with a specific frequency is applied to the skin.

[0032] In addition, in one treatment structure 20, a plurality of electrodes 21 are respectively configured to straddle different facial muscles of the user when the mask body 10 is worn on the face. The four electrodes 21 in this embodiment are respectively configured to straddle the orbicularis oculi, zygomaticus major, zygomaticus minor, and levator labii superioris of the user. For example, the first electrode 21a may also be configured near the lateral canthus. The second electrode 21b may also be configured near the medial canthus. The third electrode 21c may also be configured near the corner of the mouth. In addition, the fourth electrode 21d may also be configured at the position closest to the jaw.

[0033] The silicon gasket 23 is provided at a portion of the treatment structure 20 that directly faces the face when the mask body 10 is worn on the face. The surface shape of the silicon gasket 23 that faces the face is roughly disk-shaped along the inner surface 10a of the mask body 10. The silicon gasket 23 is soft, so it is not easy to cause discomfort to the user even if it contacts the face. In addition, the silicon gasket 23 has a plurality of through holes 23a, and the plurality of through holes 23a match the configuration of each electrode 21 so that a portion of the electrode 21 that contacts the user's face is exposed in a convex shape.

[0034] The outer shell 24 is made of resin, for example, and holds the electrode group 22 and the silicon spacer 23. When the treatment structure 20 is mounted on the housing portion 14a of the mask body 10, a portion of the outer shell 24 engages with a portion of the housing portion 14a.

[0035] The controller 30 supplies power to the electrode group 22 provided in the treatment structure 20 by the operation of the user, and controls the operation of the treatment structure 20. The controller 30 includes a controller body 31, a cover 32, and a cable 33, for example.

[0036] The controller body 31 includes a battery 34 as a power supply unit, a control substrate 35 on which a control unit 35a is mounted, and a switch button 36 as an operating unit. The battery 34 is electrically connected to the control substrate 35. A portion of the control substrate 35 is electrically connected to a connector 37 exposed to the outside from the controller body 31. The switch button 36 is operated by a user at least when the power is turned on and off, or when the first mode and the second mode described in detail below are switched. In addition, the control unit 35a is not limited to a specially designed hardware circuit to realize its function, and its function can also be realized by a processor executing a program stored in a memory.

[0037] The cover 32 covers the connector 37 provided on the controller body 31 and is detachably mounted on the controller body 31. When the cover 32 is mounted on the controller body 31, a connector (not shown) provided inside the cover 32 is fitted with the connector 37 of the controller body 31.

[0038] The cable 33 electrically connects the electrode group 22 provided in the treatment structure 20 to the controller 30. One end of the cable 33 is connected to the electrode group 22, and the other end of the cable 33 is connected to the connector of the cover 32. The electrode group 22 is electrically connected to the battery 34 and the control board 35 built into the controller body 31 via the cable 33.

[0039] The above-mentioned configuration of the controller 30 is an example. For example, the cable 33 may be detachably attached to the treatment structure 20. In addition, switches for switching the power supply and the like may be provided on the treatment structure 20 itself.

[0040] Next, the function of the cosmetic device 1 will be described.

[0041] First, the user fits the connector of the cover 32 into the connector 37 of the controller body 31, thereby electrically connecting the battery 34 and the control board 35 on the controller body 31 side to the electrodes 21 on the treatment structure 20 side via the cable 33. Then, the user attaches the pair of treatment structures 20 to the mask body 10, thereby completing the preparation of the beauty device 1 before the treatment.

[0042] Next, the user selects an operation mode (hereinafter referred to as “treatment mode”) when performing treatment using the cosmetic device 1. In the present embodiment, the control unit 35a can execute at least two treatment modes, namely, a first mode and a second mode.

[0043] The first mode is a treatment mode in which current flows over a wide area of ​​the user's face. In the first mode, current flows between the first electrode group 22a on the first treatment structure 20a side and the second electrode group 22b on the second treatment structure 20b side, that is, between the left and right sides of the face.

[0044] Figure 4 2 is a diagram for explaining the setting of the polarity of each electrode 21 in the first mode and the flow range of the current in the user's skin. Figure 4 , the mask body 10 and the pair of treatment structures 20 are shown when viewed from the side of the face of the user. On this basis, the electrode 21 whose polarity is set to the positive pole is marked with "+", and the electrode 21 whose polarity is set to the negative pole is marked with "-". In addition, the flow range of the current in the user's skin is schematically marked with a dotted line.

[0045] In the first mode, the control unit 35a performs the following steps: setting the polarities of the electrodes 21 included in one electrode group 22 to be the same, and making the polarities of the electrodes 21 different between the electrode groups 22. Figure 4 In the example shown, all four electrodes 21 included in the first electrode group 22a are set to the same polarity as positive electrodes. On the other hand, all four electrodes 21 included in the second electrode group 22b are set to the same polarity as negative electrodes. However, this setting is an example of a certain moment during the operation. Each electrode 21 included in the first electrode group 22a and each electrode 21 included in the second electrode group 22b is applied with a current as a rectangular pulse wave whose polarity is reversed at a certain period.

[0046] Such a first mode is ideal as a treatment mode for, for example, allowing beauty ingredients to permeate through the skin of the user. Here, the percutaneous penetration technology that can be applied in this embodiment can also be ion introduction (iontophoresis) that generates an osmotic flow by electrical repulsion. According to ion introduction, low molecular weight ingredients such as glycerin or vitamin C, which are beauty ingredients, can be penetrated into the deep part of the stratum corneum by using a weak current. In this case, the control unit 35a can also set the frequency of the current applied by each electrode 21 to a range of 100 Hz or more and less than 10 kHz.

[0047] In addition, the percutaneous permeation technology applicable in this embodiment may also include electroporation, which forms small holes leading to the lipid membrane through an electric field. According to the electroporation method, electroporation can be temporarily formed in the skin by using a weak current. In this case, the control unit 35a can also set the frequency of the current applied by each electrode 21 to a range of 100 Hz or more and less than 1 MHz. Moreover, by implementing ion introduction after the electroporation method, high-molecular components such as hyaluronic acid, which are beauty ingredients, can penetrate into the deep part of the stratum corneum through the formed perforations.

[0048] For example, when the first mode for performing treatment by ion introduction is selected, first, the user wets his / her face with a lotion containing beauty ingredients. Then, the user pulls the first belt 18a and the second belt 18b from the side to the back to wrap around the head while the inner surface 10a of the mask body 10 is in contact with the face, and connects the first surface connector 18c and the second surface connector 18d on the back of the head. Thus, the belt 18 applies the desired tensile force to the mask body 10, and the mask body 10 is worn on the face. Then, the user operates the switch button 36 of the controller 30 to turn on the power, and then sets the treatment mode to the first mode. Thus, a weak current flows through the entire face between the first electrode group 22a and the second electrode group 22b via the lotion, and the treatment of the first mode begins.

[0049] Next, the second mode is a treatment mode in which current is passed through a limited portion of each side of the user's face. In the second mode, current is passed through the first electrode group 22a on the first treatment structure 20a side and the second electrode group 22b on the second treatment structure 20b side.

[0050] Figure 5A to Figure 5C 2 is a diagram for explaining the setting of the polarity of each electrode 21 in the second mode and the flow range of the current in the user's skin. Figure 5A to Figure 5C In, with Figure 4 The mask body 10 and the second treatment structure 20b are shown corresponding to the VV section in FIG. 1 when viewed from the side of the face of the user. On this basis, the electrode 21 whose polarity is set to the positive pole is marked as "+", and the electrode 21 whose polarity is set to the negative pole is marked as "-". In addition, the flow range of the current in the user's skin is schematically marked with a dotted line.

[0051] In the second mode, the control unit 35a performs the following steps: energizing at least two electrodes 21 included in one electrode group 22. Figure 5AIn the first example shown, regarding the second electrode group 22b provided in the second treatment structure 20b, the first electrode 21a is set as the positive electrode and the second electrode 21b is set as the negative electrode. In this case, the current flows in a range that roughly sandwiches a portion of the orbicularis oculi muscle. Figure 5B In the second example shown, similarly with respect to the second electrode group 22b, the first electrode 21a is set as the positive electrode and the third electrode 21c is set as the negative electrode. In this case, the current flows in a range that is approximately sandwiched between the zygomatic major and the zygomatic minor muscles. Figure 5C In the third example shown, similarly with respect to the second electrode group 22b, the second electrode 21b is set as the positive electrode, and the third electrode 21c is set as the negative electrode. In this case, the current flows in a range that is approximately the range in which the levator labii superioris muscle is sandwiched. In addition, here, the focus is on the second electrode group 22b included in the second treatment structure 20b, but the same setting can also be made in the first electrode group 22a included in the first treatment structure 20a.

[0052] Such a second mode is ideal as a treatment mode for promoting muscle movement of the user's skin, for example. Here, the treatment for promoting muscle movement that can be applied in this embodiment can also be EMS (Electrical Muscle Stimulation) that uses electric current to excite nerves to produce muscle contraction. According to EMS, it is possible to stimulate the muscles of various parts of the face by using weak electric current to obtain a firming effect, etc. In this case, the control unit 35a can also set the frequency of the current applied by the appropriately selected electrode 21 to a range of greater than 1 Hz and less than 300 Hz.

[0053] For example, when the second mode of EMS treatment is selected, the user first wears the mask body 10 on the face in the same manner as described above, with the inner surface 10a of the mask body 10 in contact with the face. Then, after the user operates the switch button 36 of the controller 30 to turn on the power, the treatment mode is set to the second mode, and the part of the face to be stimulated is set. Thus, in the first electrode group 22a and the second electrode group 22b, a combination (channel) of appropriate electrodes 21 is selected to match the desired part, and a weak current flows through the skin between the selected electrodes 21, and the treatment of the second mode is started.

[0054] In addition, the electrodes 21 actually used and their polarities can be appropriately selected according to the range of the desired current flow, that is, the part of the face to be electrically stimulated. In this case, the number of electrodes 21 set as positive poles and the number of electrodes 21 set as negative poles are not limited to one, but may be two or more. In addition, the number of channels is not limited to the two exemplified above, but may be three or more.

[0055] In addition, in both the first mode and the second mode, the control unit 35 a can appropriately adjust various conditions such as the operation time or the frequency of the current applied to each electrode 21 by the user operating the switch button 36 .

[0056] Furthermore, when the user selects the second mode of treatment by operating the switch button 36 of the controller 30 after the treatment in the first mode is completed, the control unit 35a switches the treatment mode from the first mode to the second mode. Similarly, when the user selects the first mode of treatment by operating the switch button 36 of the controller 30 after the treatment in the second mode is completed, the control unit 35a switches the treatment mode from the second mode to the first mode.

[0057] Next, the effects of the cosmetics device 1 and the method for controlling the cosmetics device 1 will be described.

[0058] First, the beauty device 1 includes: a mask body 10 that can be worn on the face of a user; two electrode groups 22 that are arranged on the mask body 10 in a manner that matches the positions of the left and right cheeks of the user, and each of the two electrode groups 22 has two or more electrodes 21 for passing current to the skin of the user; and a control unit 35a. The control unit 35a switches between a first mode and a second mode. In the first mode, the polarities of the electrodes 21 included in one electrode group 22 are set to be the same, and the polarities of the electrodes 21 are made different between the electrode groups 22. In the second mode, current is passed between at least two electrodes 21 included in one electrode group 22.

[0059] The control method of the cosmetic device 1 includes the steps of: setting the polarities of the electrodes 21 included in one electrode group 22 to be the same and making the polarities of the electrodes 21 different between the electrode groups 22; and applying electricity between at least two electrodes 21 included in one electrode group 22.

[0060] According to such a cosmetic device 1 and a control method of the cosmetic device 1, it is possible to appropriately switch between the first mode, which is a treatment mode in which current is passed through a large area of ​​the user's face, and the second mode, which is a treatment mode in which current is passed through a limited area on each side of the face. Therefore, according to this embodiment, a plurality of treatments to obtain different cosmetic effects can be performed in one cosmetic device 1.

[0061] In addition, depending on certain conditions, there may be a situation where a condition that is suitable for one treatment mode is not a suitable condition for another treatment mode. For example, when considering the frequency of the current, it is desirable to set a so-called low-frequency current in the second mode. Even so, when the same low-frequency current is set in the first mode, it may sometimes cause pain to the nerves of the user's dental pulp, etc. In contrast, according to this embodiment, the first mode and the second mode are distinguished, and the desired treatment mode is appropriately switched. Therefore, it is possible to set a suitable frequency in each treatment mode, and therefore, there is the following advantage: no matter which treatment mode is selected, the user is not likely to feel discomfort, that is, the treatment feeling is not likely to be impaired.

[0062] As described above, according to the present embodiment, it is possible to provide the cosmetics device 1 that provides various cosmetic effects without impairing the feeling of treatment and the method of controlling the cosmetics device 1 .

[0063] Furthermore, in the cosmetic device 1, when performing a treatment for transdermally penetrating a cosmetic component into the user's skin, the control unit 35a may select the first mode.

[0064] According to the cosmetic device 1, when performing a transdermal permeation treatment such as iontophoresis, the first mode is adopted as a treatment mode for passing electric current over a wide area of ​​the user's face, so that the cosmetic component can be more easily permeated throughout the entire face.

[0065] In addition, in the cosmetic device 1 , the frequency of the current applied by the electrode 21 may be in the range of 100 Hz or more and less than 1 MHz.

[0066] According to the cosmetic device 1 , in the first mode, the electrode 21 is set so as to apply a high-frequency current, and therefore, stimulation to an undesired site such as a nerve can be more easily suppressed.

[0067] Furthermore, in the cosmetic device 1, when performing a treatment to promote muscle movement on the user's skin, the control unit 35a may select the second mode.

[0068] According to the beauty device 1, when performing a treatment such as EMS to promote muscle movement, a second mode is adopted as a treatment mode in which electric current is passed through a limited part on each side of the face. Therefore, it is possible to stimulate the desired part while avoiding stimulation of undesirable parts such as nerves.

[0069] Moreover, in the cosmetic device 1, the frequency of the current applied by the electrode 21 may be in the range of 1 Hz or more and less than 300 Hz.

[0070] According to the cosmetic device 1 , in the second mode, the electrode 21 is set to apply a low-frequency current, and therefore, a desired site can be further stimulated.

[0071] Furthermore, in the cosmetic device 1 , two or more electrodes 21 in the electrode group 22 may be arranged at positions straddling at least one muscle selected from the orbicularis oculi muscle, the zygomaticus major muscle, the zygomaticus minor muscle, and the levator labii superioris muscle.

[0072] According to the cosmetic device 1 , the control unit 35 a can select an appropriate electrode 21 from the plurality of electrodes 21 so that the range of current flow matches the part of the face to be stimulated.

[0073] Furthermore, the cosmetics device 1 according to the present embodiment can also be defined as follows.

[0074] The beauty device 1 may also include: a mask body that can be worn on the user's face; and two electrode groups that are arranged on the mask body in a manner that matches the positions of the left and right cheeks of the user, and each of the two electrode groups has two or more electrodes for passing current to the user's skin. In addition, the electrode polarity change unit that can change the polarity of the electrodes of the two electrode groups may include a mode switching control unit that can switch between a first mode and a second mode.
