[0003] [[Patent Document 1]] Japanese Unexamined Patent Publication No. 2020-127748 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0004] In the cosmetic device disclosed in Patent Document 1, treatment for stimulating predetermined muscles is performed by applying a low-frequency current between electrodes on one side of the face. Here, for example, when attempting to apply such electrical stimulation between the left and right electrodes of the face in order to expand the range of the face where cosmetic effects can be obtained, pain may be caused to nerves such as the user's dental pulp. In other words, with this cosmetic device, the types of cosmetic effects or the range of the face where cosmetic effects can be obtained are limited.

[0005] The present disclosure has been made in view of such problems of the prior art. The object of the present disclosure is to provide a cosmetic device or a control method for a cosmetic device that provides a plurality of cosmetic effects without impairing the treatment feeling. [[Means for Solving the Problem]]

[0006] A beauty device according to a first aspect of the present disclosure comprises a mask body worn on the user's face, two electrode groups provided on the mask body to match the positions of the user's left and right cheeks and each having two or more electrodes that conduct an electric current to the user's skin, and a control unit that switches between a first mode in which the polarity of the electrodes in one electrode group is the same, but the polarity of the electrodes in each electrode group is different, and a second mode in which current is passed between at least two electrodes in one electrode group.

[0007] Furthermore, a second aspect of the present disclosure is a control method for a beauty device comprising two electrode groups, each having two or more electrodes that conduct an electric current to the user's skin, and which are provided on a mask body worn on the user's face to match the positions of the user's left and right cheeks, the method comprising the steps of making the polarity of the electrodes in one electrode group the same, while making the polarity of the electrodes in each electrode group different, and passing an electric current between at least two electrodes in one electrode group. [Effects of the Invention]

[0008] According to this disclosure, it is possible to provide a beauty device or a method for controlling a beauty device that provides multiple beauty effects without compromising the feeling of the treatment. [Brief explanation of the drawing]

[0010] The embodiments will be described in detail below with reference to the drawings. However, unnecessary details may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted. The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims.

[0011] Figure 1 is a perspective view of a beauty device 1 according to one embodiment. Figure 2 is a plan view of the beauty device 1 as seen from the side where the mask body 10 is attached to the user's face. Figure 3 is an exploded view of the beauty device 1 as seen from the side where the mask body 10 is attached to the user's face.

[0012] Beauty device 1 employs a system in which at least a portion of it is attached to the user's face, and provides beauty effects by applying an electric current to the facial skin as electrical stimulation. Beauty devices that employ a system in which they are attached to the user's face, like beauty device 1, are sometimes called wearable facial devices or beauty masks.

[0013] The beauty device 1 comprises a mask body 10, a treatment structure 20, and a controller 30. Hereinafter, based on the user of the beauty device 1 being in a standing or sitting position and facing directly forward, the top and bottom of the mask body 10 shall correspond to the upper or lower side in the vertical direction. Also, the left and right sides of the mask body 10 shall correspond to the left cheek side or the right cheek side of the user's face.

[0014] 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. As a result, the mask body 10 is an elastic body that is flexible as a whole, and when worn on the face, the inner surface 10a deforms to conform to the shape of the face and adheres closely to the face. The inner surface 10a is the side of the mask body 10 that faces the face when in use. In this embodiment, the mask body 10 has a shape that can cover almost all areas of the face except for the eyes, nostrils, and mouth.

[0015] First, the mask body 10 has a pair of first exposure holes 11 on the left and right, a second exposure hole 12, and a third exposure hole 13 as openings. The first exposure holes 11 are formed at the top of the mask body 10 and expose the user's eyes to the outside when the mask body 10 is worn on the face. The second exposure holes 12 are formed below the first exposure holes 11 of the mask body 10 and expose the user's nostrils to the outside when the mask body 10 is worn on the face. The third exposure holes 13 are formed below the second exposure holes 12 of the mask body 10 and expose the user's mouth to the outside when the mask body 10 is worn on the face.

[0016] Furthermore, the mask body 10 has a cheek covering portion 14, a forehead covering portion 15, a chin covering portion 16, and a nose covering portion 17 as covering portions that cover the face. First, the forehead covering portion 15 is located above the first exposed hole 11 in the mask body 10 and contacts the user's forehead when the mask body 10 is worn on the face. The chin covering portion 16 is located below the third exposed hole 13 in the mask body 10 and contacts the user's chin when the mask body 10 is worn on the face. The nose covering portion 17 is located above the second exposed hole 12 in the mask body 10 such that the second exposed hole 12 opens diagonally downward toward the outside and contacts the user's nose when the mask body 10 is worn on the face. The cheek covering portion 14 is located below the first exposure hole 11, and one on each side of the nose covering portion 17, the second exposure hole 12, the third exposure hole 13, and the chin covering portion 16, so that it faces either the left or right cheek of the user when the mask body 10 is worn on the face.

[0017] Further, the mask body 10 has, on the inner surface 10a thereof, at a portion that serves as the cheek covering part 14, a housing part 14a that houses and holds the treatment structure 20. The housing parts 14a are respectively provided on the cheek covering parts 14, one on each of the left and right sides of the mask body 10. The mask body 10 may be formed with a groove 14b communicating with the housing part 14a. The groove 14b houses a part of the cable 33 connected to the treatment structure 20.

[0018] Further, the mask body 10 has a belt 18 that is wound around the head to maintain the wearing position when the mask body 10 is worn on the face. The belt 18 includes a first belt-like body 18a connected to one of the left and right lateral sides of the mask body 10, and a second belt-like body 18b connected to the other of the left and right lateral sides of the mask body 10. The first belt-like body 18a has a first hook-and-loop fastener 18c on the distal end side. Meanwhile, the second belt-like body 18b has a second hook-and-loop fastener 18d on the distal end side. When wearing the mask body 10 on the face, a user winds the first belt-like body 18a and the second belt-like body 18b around the head from the lateral sides, and engages the first hook-and-loop fastener 18c and the second hook-and-loop fastener 18d on the occipital side. Thereby, the belt 18 can allow the mask body 10 to be worn on the face while applying a desired tensile force to the mask body 10.

[0019] The treatment structure 20 operates when power is supplied thereto, and performs treatment on the user's skin. In the present embodiment, there are two treatment structures 20. One first treatment structure 20a is attached to the housing part 14a provided in the left cheek covering part 14. The other second treatment structure 20b is attached to the housing part 14a provided in the right cheek covering part 14. The first treatment structure 20a and the second treatment structure 20b have the same structure as each other and are symmetrical to each other.

[0020] Further, the treatment structure 20 is detachable from the mask body 10. By removing the treatment structure 20 from the housing part 14a, the user can clean the mask body 10 and the treatment structure 20 individually. However, the treatment structure 20 may be integrally provided on the mask body 10.

[0021] The treatment structure 20 comprises an electrode group 22 having two or more electrodes 21, a silicone pad 23, and a housing 24. Hereinafter, the electrode group 22 provided by the first treatment structure 20a will be referred to as the first electrode group 22a, and the electrode group 22 provided by the second treatment structure 20b will be referred to as the second electrode group 22b.

[0022] The electrode group 22 includes, for example, four electrodes 21: a first electrode 21a, a second electrode 21b, a third electrode 21c, and a fourth electrode 21d. The electrodes 21 are made of, for example, a titanium alloy and have a so-called button-shaped form, including a flat surface that contacts the user's skin. In this embodiment, the flat surface of the electrode 21 is circular, but it may have other shapes.

[0023] Each electrode 21 can be set as either a positive or negative electrode, i.e., GND. When at least one electrode 21 is set as a positive electrode and at least one other electrode 21 is set as a negative electrode, a potential difference is generated between these electrodes 21. Then, by applying current between these 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.

[0024] Furthermore, in a single treatment structure 20, multiple electrodes 21 are positioned so as to span different facial muscles of the user when the mask body 10 is attached to the face. In this embodiment, the four electrodes 21 are positioned so as to span the orbicularis oculi muscle, zygomaticus major and minor muscles, and levator labii superioris muscle of the user. For example, the first electrode 21a may be positioned near the outer corner of the eye. The second electrode 21b may be positioned near the inner corner of the eye. The third electrode 21c may be positioned near the corner of the mouth. The fourth electrode 21d may be positioned closest to the chin.

[0025] The silicone pad 23 is provided in the treatment structure 20 at a point that directly faces the face when the mask body 10 is attached to the face. The surface shape of the silicone pad 23 that faces the face is approximately disc-shaped, following the inner surface 10a of the mask body 10. Because the silicone pad 23 is flexible, it is less likely to cause discomfort to the user even when it comes into contact with the face. The silicone pad 23 also has multiple through holes 23a that expose a portion of the electrode 21 that comes into contact with the user's face in a convex shape, according to the arrangement of each electrode 21.

[0026] The housing 24 is made of, for example, resin and holds the electrode group 22 and the silicone pad 23. When the treatment structure 20 is attached to the housing portion 14a of the mask body 10, a part of the housing 24 engages with a part of the housing portion 14a.

[0027] The controller 30 controls the operation of the treatment structure 20 while supplying power to the electrode group 22 provided on the treatment structure 20, based on the user's operation. The controller 30 comprises, for example, a controller body 31, a cap 32, and a cable 33.

[0028] The controller body 31 comprises a battery 34 as a power supply unit, a control board 35 on which the control unit 35a is mounted, and a switch button 36 as an operation unit. The battery 34 is electrically connected to the control board 35. The control board 35 is electrically connected to a connector 37, part of which is exposed to the outside from the controller body 31. The switch button 36 is operated by the user at least to switch the power on and off, or to switch between the first mode and the second mode, which will be described in detail below.

[0029] The cap 32 covers the connector 37 provided on the controller body 31 and is detachably attached to the controller body 31. When the cap 32 is attached to the controller body 31, a connector (not shown) provided inside the cap 32 engages with the connector 37 on the controller body 31.

[0030] Cable 33 electrically connects the electrode group 22, which is provided on the treatment structure 20, to the controller 30. One end of cable 33 is connected to the electrode group 22, and the other end of cable 33 is connected to the connector on the cap 32. The electrode group 22 is electrically connected via cable 33 to the battery 34 and control board 35 built into the controller body 31.

[0031] The above configuration of the controller 30 is just one example. For example, the cable 33 may be detachable from the treatment structure 20. Also, switches for switching the power supply, etc., may be provided on the treatment structure 20 itself.

[0032] Next, I will explain the function of beauty device 1.

[0033] First, the user connects the connector of the cap 32 to the connector 37 of the controller body 31, thereby electrically connecting the battery 34 and control board 35 on the controller body 31 to each electrode 21 on the treatment structure 20 via the cable 33. Then, the user attaches the pair of treatment structures 20 to the mask body 10, completing the preparation of the beauty device 1 before treatment.

[0034] Next, the user selects an operating mode (hereinafter referred to as "treatment mode") when performing a treatment using the beauty device 1. In this embodiment, the control unit 35a can execute at least two treatment modes, a first mode and a second mode.

[0035] The first mode is a treatment mode in which an electric current is applied to a wide area of ​​the user's face. In the first mode, current is passed 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.

[0036] Figure 4 is a diagram illustrating the polarity settings of each electrode 21 and the current flow range within the user's skin in the first mode. Specifically, Figure 4 shows the mask body 10 and the pair of treatment structures 20 as seen from the side attached to the user's face. Electrodes 21 set to positive polarity are marked with a "+", and electrodes 21 set to negative polarity are marked with a "-". The current flow range within the user's skin is roughly indicated by a dashed line.

[0037] In the first mode, the control unit 35a performs the process of making the polarity of the electrodes 21 in one electrode group 22 the same, while making the polarity of the electrodes 21 different for each electrode group 22. In the example shown in Figure 4, all four electrodes 21 in the first electrode group 22a are set to the same polarity as positive poles. On the other hand, all four electrodes 21 in the second electrode group 22b are set to the same polarity as negative poles. However, this setting is an example of a timing during treatment. A current as a rectangular pulse wave is applied to each electrode 21 in the first electrode group 22a and each electrode 21 in the second electrode group 22b, causing their polarities to reverse at a constant period.

[0038] Such a first mode is suitable, for example, as a treatment mode for transdermally penetrating beauty ingredients into the user's skin. Here, the transdermal penetration technology applicable in this embodiment may be iontophoresis, which generates a penetration flow by electrical repulsion. With iontophoresis, by using a weak current, low molecular weight components such as glycerin or vitamin C as beauty ingredients can be penetrated deep into the stratum corneum. In this case, the control unit 35a may set the frequency of the current applied to each electrode 21 in the range of 100 Hz or more and less than 10 kHz.

[0039] Furthermore, the transdermal penetration technology applicable in this embodiment may include electroporation, which forms small pores in the lipid membrane using an electric field. With electroporation, temporary electroporations can be formed in the skin by using a weak current. In this case, the control unit 35a may set the frequency of the current applied to each electrode 21 to a range of 100 Hz or more and less than 1 MHz. Then, by performing iontophoresis following electroporation, high molecular weight components such as hyaluronic acid, which are used as cosmetic ingredients, can be penetrated deep into the stratum corneum through the formed perforations.

[0040] For example, if the first mode, which uses iontophoresis for treatment, is selected, the user first moistens their face with a lotion or similar product containing beauty ingredients. Next, with the inner surface 10a of the mask body 10 in contact with the face, the user wraps the first band 18a and the second band 18b around their head, pulling them from the side to the rear, and engages the first hook-and-loop fastener 18c and the second hook-and-loop fastener 18d at the back of the head. This applies the desired tension to the mask body 10 with the belt 18, and the mask body 10 is then attached to the face. The user then turns on the power by operating the switch button 36 on the controller 30, and subsequently sets the treatment mode to the first mode. As a result, a weak electric current flows across the entire face via the lotion or similar product between the first electrode group 22a and the second electrode group 22b, and the treatment in the first mode begins.

[0041] Next, the second mode is a treatment mode in which an electric current is applied to a limited area on each side of the user's face. In the second mode, current is applied individually to the first electrode group 22a on the first treatment structure 20a side and to the second electrode group 22b on the second treatment structure 20b side.

[0042] Figures 5A to 5C illustrate the polarity settings of each electrode 21 and the current flow range within the user's skin in the second mode. Specifically, Figures 5A to 5C show the mask body 10 and the second treatment structure 20b as viewed from the side attached to the user's face, corresponding to the VV cross-section in Figure 4. Electrodes 21 set to positive polarity are marked with a "+", and electrodes 21 set to negative polarity are marked with a "-". The current flow range within the user's skin is roughly indicated by dashed lines.

[0043] In the second mode, the control unit 35a performs the step of applying current between at least two electrodes 21 included in one electrode group 22. In the first example shown in Figure 5A, for 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 flow range is approximately the range that encloses a part of the orbicularis oculi muscle. In the second example shown in Figure 5B, similarly for 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 flow range is approximately the range that encloses the zygomaticus major and minor muscles. Furthermore, in the third example shown in Figure 5C, similarly for 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 flow range is approximately the range that encloses the levator labii superioris muscle. Although we have focused here on the second electrode group 22b provided in the second treatment structure 20b, the first electrode group 22a provided in the first treatment structure 20a is configured in the same way.

[0044] Such a second mode is suitable, for example, as a treatment mode that promotes muscle movement in the user's skin. Here, the treatment that promotes muscle movement that can be applied in this embodiment may be EMS (Electrical Muscle Stimulation), which excites nerves with electric current to cause muscle contraction. With EMS, by using a weak electric current, it is possible to stimulate the muscles of various parts of the face and obtain a tightening effect, etc. In this case, the control unit 35a may set the frequency of the current applied to the appropriately selected electrode 21 in the range of 1 Hz or more and less than 300 Hz.

[0045] For example, when the second mode, which uses EMS for treatment, is selected, the user first places the mask body 10 on their face with the inner surface 10a of the mask body 10 in contact with their face, as described above. Then, the user turns on the power by operating the switch button 36 on the controller 30, sets the treatment mode to the second mode, and sets the area of ​​the face that they want to be stimulated. As a result, the first electrode group 22a and the second electrode group 22b each select an appropriate combination (channel) of electrodes 21 according to the desired area, and a weak electric current flows through the skin between the selected electrodes 21, initiating treatment in the second mode.

[0046] The electrodes 21 and their polarity used can be appropriately selected depending on the area to which the current is to be passed, that is, the area of ​​the face to which electrical stimulation is to be applied. In this case, the number of electrodes 21 set as positive electrodes and the number of electrodes 21 set as negative electrodes are not limited to one each, but may be two or more. Similarly, the number of channels is not limited to the two exemplified above, but may be set to three or more.

[0047] Furthermore, in both the first and second modes, the control unit 35a may appropriately adjust various conditions such as the treatment time or the frequency of the current applied to each electrode 21 by operating the switch button 36 by the user.

[0048] Then, after the treatment in the first mode is completed, if the user selects to continue with the treatment in the second mode by operating the switch button 36 on the controller 30, the control unit 35a switches the treatment mode from the first mode to the second mode. Similarly, after the treatment in the second mode is completed, if the user selects to continue with the treatment in the first mode by operating the switch button 36 on the controller 30, the control unit 35a switches the treatment mode from the second mode to the first mode.

[0049] Next, we will explain the effects of beauty device 1 and the control method for beauty device 1.

[0050] First, the beauty device 1 comprises a mask body 10 that is attached to the user's face, two electrode groups 22 provided on the mask body 10 to match the positions of the user's left and right cheeks, each having two or more electrodes 21 that conduct electric current to the user's skin, and a control unit 35a. The control unit 35a switches between a first mode in which the polarity of the electrodes 21 included in one electrode group 22 is the same, but the polarity of the electrodes 21 differs for each electrode group 22, and a second mode in which current is passed between at least two electrodes 21 included in one electrode group 22.

[0051] Furthermore, the control method for the beauty device 1 includes the steps of making the polarity of the electrodes 21 included in one electrode group 22 the same, while making the polarity of the electrodes 21 different for each electrode group 22, and the step of passing current between at least two electrodes 21 included in one electrode group 22.

[0052] With this beauty device 1 and control method, it is possible to appropriately switch between a first mode, which is a treatment mode that applies electric current to a wide area of ​​the user's face, and a second mode, which is a treatment mode that applies electric current to limited areas on each side of the face. Therefore, according to this embodiment, multiple treatments that yield different beauty effects can be performed with a single beauty device 1.

[0053] Furthermore, under certain conditions, conditions that are suitable for one treatment mode may not be suitable for the other treatment mode. For example, considering the frequency of the current, even if it is desirable to set a so-called low-frequency current in the second mode, if the same low-frequency current is set in the first mode, it may cause pain to the nerves such as the dental pulp of the user. In contrast, according to this embodiment, the first mode and the second mode are distinguished, and the system switches to the desired treatment mode as appropriate. Therefore, since the appropriate frequency can be set for each treatment mode, regardless of which treatment mode is selected, the user is less likely to feel discomfort, that is, the treatment sensation is less likely to be impaired.

[0054] As described above, this embodiment provides a beauty device 1 and a control method for the beauty device 1 that provide multiple beauty effects without compromising the feeling of the treatment.

[0055] Furthermore, in the beauty device 1, the control unit 35a may select the first mode when a treatment is being performed to penetrate beauty ingredients transdermally into the user's skin.

[0056] According to this beauty device 1, when performing transdermal penetration treatments such as iontophoresis, the first mode is adopted as a treatment mode that applies electric current to a wide area of ​​the user's face, making it easier to penetrate beauty ingredients into the entire face.

[0057] Furthermore, in beauty device 1, the frequency of the current applied to the electrode 21 may be in the range of 100 Hz or more and less than 1 MHz.

[0058] According to this beauty device 1, in the first mode, the electrode 21 is set to apply an approximately high-frequency current, making it easier to suppress stimulation of unwanted areas such as nerves.

[0059] In addition, in beauty device 1, the control unit 35a may select the second mode when a treatment is performed on the user's skin that promotes muscle movement.

[0060] According to this beauty device 1, when performing treatments that promote muscle movement such as EMS, a second mode is adopted as a treatment mode that applies electric current to a limited area on each side of the face, so that the desired area can be stimulated while avoiding stimulation of unwanted areas such as nerves.

[0061] Furthermore, in beauty device 1, the frequency of the current applied by electrode 21 may be in the range of 1 Hz or more and less than 300 Hz.

[0062] According to this beauty device 1, in the second mode, the electrode 21 is set to apply an approximately low-frequency current, so that the desired area can be stimulated more effectively.

[0063] Furthermore, in beauty device 1, two or more electrodes 21 in the electrode group 22 may be positioned to span at least one muscle selected from the orbicularis oculi muscle, the zygomaticus major and minor muscles, and the levator labii superioris muscle.

[0064] According to this beauty device 1, the control unit 35a can select the appropriate electrode 21 from a plurality of electrodes 21 so that the current flow range matches the area of ​​the face to be stimulated.

[0065] Furthermore, the beauty device 1 according to this embodiment can also be defined as follows.

[0066] The beauty device 1 may have a mask body that is attached to the user's face, and two electrode groups provided on the mask body to match the positions of the user's left and right cheeks, each having two or more electrodes that conduct electric current to the user's skin. Furthermore, the electrode polarity changing unit, which can change the polarity of the electrodes in the two electrode groups, may have a mode switching control unit that can switch between a first mode and a second mode. In the first mode, the polarity of the electrodes included in one of the two electrode groups is made the same, and the polarity of the electrodes is changed to be different for each electrode group, and current is passed between the electrode groups with different polarities. In the second mode, current is passed between at least two electrodes included in one electrode group.

[0067] Furthermore, in the beauty device 1, the electrode polarity changing section may increase the frequency of the current passed between electrode groups with different electrode polarities in the first mode.

[0068] Furthermore, in the beauty device 1, the electrode polarity changing section may, in the first mode, select electrodes such that the distance between electrodes that conduct electricity between electrode groups with different polarities is greater.

[0069] Furthermore, in beauty device 1, the electrode polarity changing section may, in the second mode, detect the inter-painless area, which is the area between painless areas that does not cause unpleasant stimulation (pain), and may also apply current between at least two electrodes that are close to the inter-painless area.

[0070] Here, the mask body part corresponds to the mask body 10, and the electrode group part corresponds to the electrode group 22 having two or more electrodes 21. Furthermore, the electrode polarity changing unit and the mode switching control unit are components that may be included in the control unit 35a.

[0071] Since the embodiments described above are for illustrative purposes of the technology described herein, various modifications, substitutions, additions, omissions, etc., can be made within the scope of the claims or equivalents thereof.

[0072] For example, the above description illustrates a case where each electrode group 22 includes four electrodes 21: a first electrode 21a, a second electrode 21b, a third electrode 21c, and a fourth electrode 21d.

Claims

[Claim 1] The mask body is worn on the user's face, The mask body is provided with two electrode groups, each having two or more electrodes that conduct electric current to the user's skin, positioned to match the left and right cheeks of the user. Furthermore, the electrode polarity changing unit, which can change the polarity of the electrodes in the two electrode groups, has a mode switching control unit that can switch between a first mode in which the polarity of the electrodes included in one of the two electrode groups is made the same, and the polarity of the electrodes is changed to be different for each electrode group, and current is passed between the electrode groups with different electrode polarities, and a second mode in which current is passed between at least two of the electrodes included in one of the electrode groups. The electrode polarity changing unit is a beauty device that, in the first mode, can select electrodes such that the distance between electrodes that are energized in the electrode group with different polarities is greater than the distance between the electrodes.
