[Modes for carrying out the invention]

[0025] 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.

[0026] The attached drawings and the following description are provided to enable a person skilled in the art to fully understand the technology relating to this disclosure, and are not intended to limit the subject matter described in the claims.

[0027] The mask-type beauty device 1 has a function that delivers electrical stimulation to the face, and it is possible to switch the electrical stimulation on and off. When the electrical stimulation is on, it is possible to switch the output level of the electrical stimulation from 1 to 3 levels. The mask-type beauty device 1 is equipped with green, red, and yellow light irradiation modes for the face. Furthermore, the irradiation mode can be changed depending on the area of ​​the face, with the selectable areas being the forehead, eye area, and cheeks. Furthermore, the heat generated when electrical stimulation is applied to the face, and the light emitted when light is shone on it, can increase skin temperature.

[0028] The control unit 27 (controller), described later, of the mask-type beauty device 1 is an external component of the mask-type beauty device 1, is integrated with the housing 9 made of a flexible material, and is equipped with an indicator that displays the mode.

[0029] The stimulator 2, which applies electrical stimulation to the face or irradiates the face with light, may include, but is not limited to, halogen, IPL, organic EL, laser, interferential wave, ultrasound, sound wave, vibration, heating, plasma, etc.

[0030] Refer to Figures 1(a), (b) and 3. Figure 1(a) is a front view of the mask-type beauty device 1 in this example, and Figure 1(b) is a rear view of the mask-type beauty device 1 in this example. Figure 3 is a perspective view of the mask-type beauty device 1.

[0031] As shown in Figure 1(b), the mask-type beauty device 1 is equipped with multiple electrodes 3 (which can be switched between three levels using EMS (Electric Muscle Stimulation), etc., hereinafter referred to as EMS electrodes) and multiple LEDs 5 (Light-Emitting Diodes).

[0032] A single LED 5 may be equipped with four chips (infrared preferably 850nm in the range of 790-900nm, red preferably 630nm in the range of 610-650nm, green preferably 505nm in the range of 485-525nm, and yellow preferably 590nm in the range of 570-610nm). For example, if the target areas of the face are the forehead and cheeks, the three modes described above (green, red, and yellow) may be combined to form a total of nine modes for irradiating the face. Furthermore, the device allows for treatments involving only electrical stimulation, only light irradiation, or both electrical stimulation and light irradiation to the face. This switching is performed by the control unit 27.

[0033] For example, in area E1, the forehead is treated, and in area E2, the cheeks are treated. Other options include treating only the forehead, only the eye area, only the cheeks, switching between treating the forehead, eye area, and cheeks, or selecting one or more areas for treatment. When performing light irradiation, it is possible to select a mode for each area being treated, or to select the same mode for all areas. Mode switching is controlled by the control unit 27.

[0034] As shown in Figure 2, the mask-type beauty device 1 is integrally equipped with a housing 9 that covers the outside (flexible circuit board 15, transparent cover 17, and the face, etc., described later) and a storage unit 7 (in which the control unit 27 is built-in). The storage unit 7 may be, for example, a storage case, but is not limited to this. The housing 9 of the mask-type beauty device 1 may have a hollow space, or it may have slits or pockets. Alternatively, a detachable part may be provided on the surface of the housing 9 of the mask-type beauty device 1 so that the control unit 27 can be attached. In other words, the storage unit 7 may be configured to be detachable from the housing 9.

[0035] Refer to Figures 3(a), (b), (c), and (d). Figure 3 shows the folding pattern of the mask-type beauty device 1. In the first pattern, as shown in Figures 3(a), (b), and (c), the folding parts 11a, 11b, and 11c are simultaneously folded toward the inner surface (face side) of the housing 9 and secured by a pair of hook-and-loop fasteners 13 provided on the sides (ear portions) of the housing 9. At this time, the interior angles of the two planes based on the folding parts 11a, 11b, and 11c are configured to be between 0 and 90 degrees. The preferred angle for each interior angle is between 0 and 45 degrees. A more preferred angle is between 0 and 10 degrees. Furthermore, in the flexible circuit board 15 provided on the inner surface of the housing 9, the space between the flexible circuit board 15a and the flexible circuit board 15b is folded in accordance with the folding portion 11a. The flexible circuit board 15 is divided into multiple sections (at least two sections), and has flexible lead wires 24 (cables) connecting the multiple sections of the flexible circuit board 15. Furthermore, the transparent cover 17, which is made of silicone rubber and is provided on the inner surface of the flexible substrate 15, is also folded. In this way, after the mask-type beauty device 1 is folded, the hook-and-loop fastener 13 secures the mask-type beauty device 1 and maintains its folded state.

[0036] In the second pattern, as shown in Figures 3(a) and (d), only the folding portion 11a is folded inward towards the inner surface of the housing 9. In this case, the interior angles of the two planes with respect to the folding portion 11a are configured to be between 0 and 45 degrees. On the other hand, the housing 9 is flexible and foldable and has flexible lead wires 24 connecting the flexible substrate 15a and the flexible substrate 15b. The housing 9 is folded in the portion between the flexible substrate 15a and the flexible substrate 15b through which these flexible lead wires 24 pass. Furthermore, the transparent cover 17 made of silicone rubber is also folded. In this way, after the mask-type beauty device 1 is folded, the hook-and-loop fastener 13 secures the mask-type beauty device 1 and maintains its folded state.

[0037] Refer to Figures 4 and 5. Figure 4 is a front view of the mask-type beauty device 1 equipped with left and right fixing belts 19. Figure 5 is a rear view of the mask-type beauty device 1 equipped with left and right fixing belts 19. Each of the left and right fixing belts 19 is a fixing means provided on the housing 9 that secures the mask-type beauty device 1 to the face, and is a strip-shaped member formed so that its height increases as it approaches the housing 9. Each of the left and right fixing belts 19 has a rectangular opening at the ear area when worn on the face. In addition, the lower part 19b of each of the left and right fixing belts 19 may have a height dimension sufficient to lift and hold the chin when worn on the face. Furthermore, the left and right fixing belts 19 may be inserted into the housing 9 and secured with magnets or the like, or they may be integrated with the housing 9. Flexible bands or the like can be used as the left and right fixing belts 19. In addition, retaining bands, magnets, or even fasteners can be used to connect the left and right fixing belts 19 to each other. Other methods may also be used, such as using Velcro (registered trademark) or tying the fixing belts 19 together.

[0038] Figures 6(a), (b), (c), and (d) show the main components of the mask-type beauty device 1. Figure 6(a) is the housing 9. Figure 6(b) is the flexible circuit board 15. In this example, for example, the flexible circuit board 15 is divided into two parts, but details will be described later. Figure 6(c) is the transparent cover 17, which is made of silicone rubber. Figure 6(d) are the left and right fixing belts 19. That is, the transparent cover 17 is in contact with the face, the flexible circuit board 15 is placed so as to overlap the transparent cover 17, and finally it is wrapped by the housing 9. On the other hand, the left and right fixing belts 19 may be inserted into the housing 9 and fixed with magnets or the like, or they may be integrated. Retaining bands, magnets, or even fasteners can be used to connect the left and right fixing belts 19 to each other. In addition, other methods such as using Velcro (registered trademark) or tying the fixing belts 19 together may be used. Components such as the battery 25, control unit 27, and coil spring 39 will be described later. Note that the battery 25 may be included in the external control unit 27 instead of the housing 9.

[0039] Refer to Figure 7. In this example, the flexible substrate 15 is divided into two parts. The housing 9 holds the two divided flexible substrates 15a and 15b via an ABS resin fixing plate 21. Furthermore, a transparent cover 17 is positioned via the ABS resin fixing plate 21. By dividing the flexible circuit board 15 into flexible circuit board 15a and flexible circuit board 15b, it is easy to fold the flexible circuit board 15 to match the folding section 11a of the housing 9. Furthermore, the flexible circuit board 15a and flexible circuit board 15b are connected by lead wires 24.

[0040] Refer to Figure 8. The left and right fixing belts 19 of the mask-type beauty device 1 are inserted into the left and right fixing belt insertion holes 19a and fixed with magnets 23, but are not limited to this and may be integrated with the housing 9. Retaining bands, magnets, and even fasteners can be used to connect the fixing belts 19 to each other. Other methods may also be used, such as using Velcro (registered trademark) or tying the fixing belts 19 together. The housing 9 of the mask-type beauty device 1 houses the battery 25 and the control unit 27, and the battery 25, the control unit 27, the flexible circuit board 15a, and the flexible circuit board 15b are connected. The flexible circuit board 15a and the flexible circuit board 15b are connected by lead wires 24, and the housing 9 is positioned to cover the flexible circuit board 15a and the flexible circuit board 15b, but a heat shield sheet 29 or the like may be placed between them.

[0041] Refer to Figures 9(a) and (b). The housing 9, which is made of silicone rubber, has a folding portion 11, but multiple protrusions 31 may be formed in the silicone rubber, and the recesses between them may be used as the folding portion 11. The housing 9 is configured such that flexible substrates 15a and 15b are placed adjacent to each other on its inner surface, separated by narrow grooves which are recesses, so that the narrow grooves between the flexible substrates 15 become the folding portion 11. Furthermore, since the protrusion 31 is a design surface, printing 33 is applied to its surface.

[0042] Refer to Figures 10(a), (b), and (c). The cross-section AA of Figure 10(a) is shown in two patterns in Figures 10(b) and 10(c). As shown in Figure 10(b), a flat part 35 (plastic top) with a higher hardness than the outermost housing 9 is attached to the outermost housing 9 to make it easier to fold. This flat part 35 makes it easier to see where to fold and prevents damage to the flexible substrates 15a and 15b. The flat part 35 is attached with adhesive 37. In the other pattern, as shown in Figure 10(c), if the housing 9 is made of silicone rubber or the like, the flat part 35 is attached with adhesive 37 in a position where it is half-embedded in the housing 9. The mask-type beauty device 1 maintains its three-dimensional shape with the flat part 35. The flat part 35 also comes in multiple sizes and may be configured to be symmetrical. Furthermore, the mask-type beauty device 1 may be composed of multiple surfaces with varying thicknesses and irregularities formed on the housing 9, rather than a flat part 35.

[0043] Refer to Figures 11(a), (b), (c), (d), (e), and (f). Figure 11(a) shows the control unit 27. The control unit 27 controls the stimulation unit 2, which includes at least one of either an EMS electrode 3, which is an electrical stimulation unit that provides electrical stimulation to the face, or an LED 5, which is a light-emitting unit that irradiates light onto the face. Furthermore, a flexible circuit board 15 is placed on the inner side of the housing 9, and multiple LEDs 5 constituting the light-emitting part are placed on the flexible circuit board 15. A transparent cover 17 is placed on the inner side of the flexible circuit board 15, and EMS electrodes 3 constituting part of the electrical stimulation part are placed on the transparent cover 17.

[0044] As shown in Figure 11(b), the flexible substrate 15 is divided into two parts: flexible substrate 15a and flexible substrate 15b. The housing 9 is constructed by placing the flexible substrate 15 on an ABS resin fixing plate 21, and then placing a transparent cover 17 on top of it. By dividing the flexible substrate 15 into flexible substrate 15a and flexible substrate 15b, it is made easy to fold it to match the folding part 11 of the housing 9.

[0045] Figure 11(c) shows the battery 25. This battery 25 supplies power to the control unit 27, flexible circuit board 15, LED 5, and EMS electrode 3, etc.

[0046] Figure 11(d) shows the coil spring 39 (biasing member). As shown in Figures 11(e) and 11(f), the multiple EMS electrodes 3 are arranged in the transparent cover 17 and electrically connected to the flexible substrate 15 via the coil spring 39. The transparent cover 17 also has electrode mounting holes 17a, into which the EMS electrodes 3 are mounted so that they cannot be removed, with the electrode surface exposed on the inner side. A coil spring 39 is provided between the EMS electrodes 3 and the flexible substrate 15 to bias the EMS electrodes 3 toward the face. Furthermore, a sponge 38 is provided between the transparent cover 17 to which the EMS electrode 3 is attached and the flexible substrate 15 to prevent contact between the EMS electrode 3 and the flexible substrate 15 when the EMS electrode 3 is pressed against the face. This sponge 38 prevents the EMS electrode 3 from coming into contact with the flexible substrate 15 even when pressed against the face, thus reducing the transfer of heat from the flexible substrate 15 to the EMS electrode 3.

[0047] Furthermore, the surface of the EMS electrode 3 is coated with cosmetics (not shown) or a conductive gel pad (not shown) is attached. Therefore, the EMS electrode 3 comes into contact with the face via these conductive gel pads, etc. If a conductive gel pad is attached, a carbon sheet (not shown) may be provided on the surface of the EMS electrode 3 to improve the adhesion between the EMS electrode 3 and the conductive gel pad. Alternatively, a sheet mask impregnated with cosmetics may be attached to the entire inner surface of the housing 9, or a conductive gel pad may be attached to the entire inner surface of the housing 9. In addition, instead of cosmetics being applied to the surface of the EMS electrode 3, cosmetics may be applied to the face.

[0048] Refer to Figures 12 and 13. The housing 9 of the mask-type beauty device 1 is positioned furthest from the face. The housing 9 is provided with a space enclosed by a case 41 and a case 43 for housing the battery 25. Furthermore, it is provided with a storage section 7 enclosed by a case 45 and a case 47 for housing the control unit 27.

[0049] On the inner surface of the housing 9, a flexible circuit board 15a and a flexible circuit board 15 are arranged. This flexible circuit board 15 is divided into two parts: flexible circuit board 15a and flexible circuit board 15b. A transparent cover 17 is positioned at the location that comes into contact with the face. These components together constitute the mask-type beauty device 1.

[0050] Refer to Figures 14 and 15. To make the mask-type beauty device 1 easy to fold, it is desirable to minimize the number of layers at the folding point. For this reason, although a lead wire 24 is provided at the folding part 49 that contacts the nose, the casing 9 may be eliminated and the device may be constructed using only a transparent cover 17 and the lead wire 24, thereby making the folding part 49 easier to fold.

[0051] With this configuration, the mask-type beauty device 1 folds into a flat shape when not in use and unfolds into a three-dimensional shape when in use. Furthermore, when in use, the folding part 11 of the housing 9 is positioned such that the mask-type beauty device 1 unfolds into a three-dimensional shape by pulling open each surface adjacent to the folding part 11, with the folding part 11 as the center. In addition, the mask-type beauty device 1 is formed such that the size when folded into a flat shape is 50% or less of the size when the housing 9 is unfolded into a three-dimensional shape.

[0052] In this way, when the mask-type beauty device 1 is removed from the face, it can be folded and stored in a narrow space, and the mask-type beauty device 1 is obtained in which dust and other particles do not adhere to the inside.

[0053] (First variation) Next, a first modified example of the mask-type beauty device 1 described above will be explained. Refer to Figures 16, 17, 18, and 19. Figure 16 is a perspective view of a mask-type beauty device relating to the first modification of this embodiment, where (a) shows the control unit attached and (b) shows the control unit removed. Figure 17 is an explanatory diagram showing the nasal and oral ventilation parts of the mask-type beauty device. Figure 18 is an explanatory diagram of the main part of the back of the mask-type beauty device. Figure 19 is the back side of the mask-type beauty device, where (a) is a rear view and (b) is an enlarged view of the main part. Figure 20 is a cross-sectional view of BB in Figure 19. In this modified mask-type beauty device 61, the differences from this embodiment will be described below.

[0054] Refer to Figures 16, 17, and 18. The housing 62 of the mask-type beauty device 61 is configured such that multiple polygonal regions 62a, including triangles, are arranged adjacent to each other, and narrow grooves 62b are formed between each region. The portion where the narrow grooves 62b are formed is made thin, thereby forming the folding portion 11. For this reason, the housing 62 does not require a flat part 35 and can be formed as a single piece. In addition, although the housing 62 of the mask-type beauty device 61 is described as having a thin wall in the portion where the fine groove 62b is formed, it is not limited to this, and the folding portion 11 may be formed by the rigidity of the portion where the fine groove 62b is formed being lower than the rigidity of the polygonal region 62a. Furthermore, the housing 62 is equipped with a nasal vent 65 and a mouth vent 66. These nasal and mouth vents 66 make it easier to breathe when wearing the mask-type beauty device 61.

[0055] The storage unit 63, which is separate from the housing 62 and detachable, is provided on the upper part 19c of either the left or right fixing belt 19. The storage unit 63 is formed as a case capable of housing the control unit 27 and the battery 25. The shape of the storage section 63 is not limited to an L shape; it may also be V-shaped, as shown in Figure 19. This V-shaped storage section 63a is attached to conform to the shape of a person's head, making it easy to wear. Also, as shown in Figure 20, the operating surface 63b of the storage section 63a is attached at an angle to the height. Therefore, when pressing the button (not shown) on the operating surface 63b while wearing the mask-type beauty device 61, the force applied to the button on the operating surface 63b is transmitted diagonally downward rather than horizontally, thus reducing the load on the head. A detachable section 64 for attaching and detaching the storage section 63 is provided on the upper part 19c of either the left or right fixing belt 19. By providing the storage section 63 on the detachable section 64, the flexibility of the upper part 19c of the fixing belt 19 on which the detachable section 64 is located is lost, but the flexibility of the lower part 19b of the fixing belt 19 can be maintained. A transparent cover 17 is provided on the inner side (face side) of the upper part 19c of the fixing belt 19, where the attachment / detachment part 64 is located, extending to the attachment / detachment part 64, and one end of a lead wire 67 is connected to the attachment / detachment part 64. The other end of the lead wire 67 is joined to the flexible circuit board 15. This allows for the connection of the control unit 27, the battery 25, and the flexible circuit board 15. Furthermore, as shown in Figure 21, the left and right fixing belts 19 have bellows sections 19d, which makes it easier for the left and right fixing belts 19 to bend in the winding direction.

[0056] Refer to Figure 22(a). The EMS electrode 3 comprises a first electrode 3a, a second electrode 3b, a third electrode 3c, a fourth electrode 3d, and a fifth electrode 3e. The first electrode 3a, the second electrode 3b, and the third electrode 3c are attached to the transparent cover 17 so as to deliver electrical stimulation to the cheek. The fourth electrode 3d and the fifth electrode 3e are attached to the transparent cover 17 so as to deliver electrical stimulation to the eye area.

[0057] Refer to Figure 22(b). The housing 62 has an opening 71 that opens the eye area to the outside, and an eye cup 68 is provided in at least a part of the opening 71 to block out external light. The eye cup 68 is convex towards the face and is formed from an upper part 68a around the eye, a side part 68b (towards the ear), and a lower part 68c. The eye cup 68 is not located at the nose and does not interfere when the housing 62 is folded to the left or right. Furthermore, as shown in Figure 23, the eye cups 68 may be provided so that the left and right sides are continuous at the nose. In this case, the eye cups 68 have connecting parts 68d that connect the left and right upper parts 68a and lower parts 68c, improving light shielding. In addition, the connecting parts 68d are foldable at the center in the left-right direction and do not hinder the folding of the mask-type beauty device 61.

[0058] Refer to Figure 24. Three heat-insulating and light-shielding sponges 69, a shaft 70, and lead wires 24 are provided between the housing 62 and the flexible circuit board 15. In the heat-insulating and light-shielding sponge 69, a pair of heat-insulating and light-shielding sponges 69a are provided adjacent to the inner surface of the housing 62 and spaced apart from each other in the left-right direction from the center position where the housing 62 is folded left and right. In addition, a heat-insulating and light-shielding sponge 69b is provided at the center position where the housing 62 is folded left and right, spaced apart from the inner surface of the housing 62, so there are a total of three heat-insulating and light-shielding sponges 69. The shaft 70 is positioned at the center where the housing 62 folds to the left and right, extending vertically. The shaft 70 is located adjacent to the heat-insulating and light-shielding sponge 69b on the inner surface (face side) of the heat-insulating and light-shielding sponge 69b. The lead wire 24 is provided to pass through the inner surface of the heat-insulating and light-shielding sponge 69a and through the housing 62 side of the heat-insulating and light-shielding sponge 69b. Therefore, when the housing 62 is folded, the degree of bending of the lead wires 24 is mitigated by the heat-insulating and light-shielding sponge 69 and the shaft 70, reducing the risk of excessive force being applied to the lead wires 24 and causing them to break. Furthermore, the heat-insulating and light-shielding sponge 69 plays a role in preventing heat from the flexible circuit board 15 from being transferred to the housing 62, and in preventing light from the LED 5 from leaking to the housing 62. Furthermore, the mask-type beauty device 61 may be configured to transmit the light emitted from the LED 5 to the housing 62. Specifically, as shown in Figures 25 and 26, when the LED 5 emits light, the light passes through the transparent cover 17 and travels from the projection 17c of the transparent cover 17 towards the housing 62, so that the light emitted from the LED 5 can be recognized from the outside. Also, if the color of the light emitted from the LED 5 and the color of the housing 62 are similar (for example, if the LED 5 is red and the housing 62 is red), the light from the LED 5 is easily transmitted.

[0059] With the configuration described above, the mask-type beauty device 61 is easy to fold, just like in this embodiment. Furthermore, the exterior of the housing 62 is presented in a tile-like pattern, giving it an excellent design. In this modified example, the mask-type beauty device 61 can be easily folded, protecting the inside from dust and other debris.

[0060] (Second variation) Next, a second modification of the mask-type beauty device 1 described above will be explained. The following explains the differences from the first variation.

[0061] In the second variation, the arrangement of LED5 is determined based on the power supply voltage (V), the voltage Vf that causes LED5 to light up, and the number of LED5 used.

[0062] Specifically, let's assume, for example, that the power supply voltage is 6.4V, and that nine LED5s are needed in one of the different areas of the face (forehead, cheeks, etc.). Also, let's assume that the emission voltage Vf of the infrared chip of LED5 is 1.45V, and the current consumption (A) is 0.06A. In this case, as shown in Figure 27, the infrared chips of LED5 are arranged in series of four (power supply voltage 6.4V > infrared chip emission voltage Vf 1.45V × 4 in series) and in parallel of three (4 in series × 3 in parallel > number of LED5 (9) ÷ 4 in series).

[0063] In this case, the current consumption can be calculated by multiplying it by the number of LEDs (5) connected in parallel, so the current consumption is 0.06A × 3 in parallel = 0.18A. A similar calculation is used to determine the current consumption of the infrared chips in other parts of the face. Then, the current consumption values ​​for each part of the face are added together, and the sum of these values ​​becomes the total current consumption of the infrared chips.

[0064] Therefore, the power consumption (W) of the infrared chip can be calculated by multiplying the total current consumption (A) of the infrared chip by the power supply voltage of 6.4V. Using a similar calculation, the power consumption of the red, yellow, and green LED chips of LED5 can be calculated, and their sum is the total power consumption, thus determining the power consumption of battery 25.

[0065] For example, if the red chip of LED5 has an emission voltage Vf of 2.00V and a current consumption (A) of 0.03A, then the red chips of LED5 are arranged in series as follows: 3 in series (power supply voltage 6.4V > emission voltage Vf of red chip 2.00V × 3 in series) and 4 in parallel (3 in series × 4 in parallel > number of LED5 (9) ÷ 3 in series). In this case, the current consumption can be calculated by multiplying it by the number of LEDs (5) connected in parallel, so the current consumption is 0.03A × 4 LEDs in parallel = 0.12A. A similar calculation is used to determine the current consumption of the red chips on other parts of the face. Then, the current consumption values ​​for each part of the face are added together, and the sum of these values ​​becomes the total current consumption of the red chips. Therefore, the power consumption (W) of the red chip can be calculated by multiplying the total current consumption (A) of the red chip by the power supply voltage of 6.4V.

[0066] For example, if the yellow chip of LED5 has an emission voltage Vf of 1.90V and a current consumption (A) of 0.025A, then the yellow chips of LED5 are arranged in series as follows: 3 in series (power supply voltage 6.4V > emission voltage Vf of yellow chip 1.90V × 3 in series) and 4 in parallel (3 in series × 4 in parallel > number of LED5 (9) ÷ 3 in series). In this case, the current consumption can be calculated by multiplying it by the number of LEDs (5) connected in parallel, so the current consumption is 0.025A × 4 LEDs in parallel = 0.10A. A similar calculation is used to determine the current consumption of the yellow chips on other parts of the face. Then, the current consumption values ​​for each part of the face are added together, and the sum of these values ​​becomes the total current consumption of the yellow chips. Therefore, the power consumption (W) of the yellow chip can be calculated by multiplying the total current consumption (A) of the yellow chip by the power supply voltage of 6.4V.

[0067] For example, if the green chip of LED5 has an emission voltage Vf of 3.10V and a current consumption (A) of 0.025A, then the green chips of LED5 are arranged in series as follows: 2 in series (power supply voltage 6.4V > green chip emission voltage Vf 3.10V × 2 in series) and 6 in parallel (2 in series × 6 in parallel > number of LED5 (9) ÷ 2 in series). In this case, the current consumption can be calculated by multiplying it by the number of LEDs (5) connected in parallel, so the current consumption is 0.025A × 6 LEDs in parallel = 0.15A. A similar calculation is used to determine the current consumption of the green chips on other parts of the face. Then, the current consumption values ​​for each part of the face are added together, and the sum of these values ​​becomes the total current consumption of the green chips. Therefore, the power consumption (W) of the green chip can be calculated by multiplying the total current consumption (A) of the green chip by the power supply voltage of 6.4V.

[0068] While the most efficient power supply voltage for the LED5 array is, for example, 6.4V, other values ​​may also be used.

[0069] The optimal emission voltage (Vf) for each LED5 chip is as follows: infrared chip is in the range of 0.04 to 2.40V, red chip is in the range of 0.10 to 3.40V, yellow chip is in the range of 0.10 to 3.40V, and green chip is in the range of 0.02 to 4.40V. Furthermore, if the power supply voltage of LED5 is, for example, 6.4V, the emission voltage Vf of each LED5 chip is in the range of 1.00 to 1.59V for the infrared chip, 1.00 to 2.10V for the red chip, 1.00 to 2.10V for the yellow chip, and 1.00 to 3.19V for the green chip.

[0070] With the configuration described above, the LED5 can be arranged efficiently (efficiently in terms of power consumption). Specifically, the LED5 should be arranged in a way that is a common multiple of the infrared chips (which can be arranged in series of 4), the red and yellow chips (which can be arranged in series of 3), and the green chips (which can be arranged in series of 2) (for example, 12, 24, 36, etc.). Furthermore, each LED5 is equipped with four chips (infrared chip, red chip, yellow chip, and green chip). Therefore, it can exhibit a higher anti-aging effect on human skin than typical LEDs that have three chips (red chip, yellow chip, and green chip). Furthermore, instead of providing different power supply voltages for each chip, fixing the power supply voltage (for example, 6.4V) allows for miniaturization of the control unit 27. Note that the power supply voltage does not necessarily have to be fixed. Furthermore, in the second modified example, the method can be applied not only when the mask-type beauty devices 1 and 61 are folded, but also when the mask-type beauty devices 1 and 61 are not folded.
