Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the beauty device described in Patent Document 1, since the first current is passed between the central electrode and the hand electrode, and the second current is passed between different outer peripheral electrodes, the number of electrodes in the head part increases. Therefore, in the beauty device described in Patent Document 1, due to the increase in the size of the head part, it is likely to be difficult to perform delicate procedures on minute treatment sites and the like.

[0006] This disclosure has been made in view of the problems of the prior art. The purpose of this disclosure is to provide a beauty device that can conduct currents with different characteristics while keeping the head small, thereby enabling high beauty effects through precise treatment. [Means for solving the problem]

A first output voltage having a first frequency is applied between a pair of proximity electrodes that are closer than a pair of electrodes at both ends of the parallel electrode group, and a second output voltage having a second frequency lower than the first frequency is applied between a pair of distance electrodes that are further away than the proximity electrode pair. [Effects of the Invention]

Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments will be described in detail with reference to the drawings. However, a more detailed description than necessary may be omitted. For example, a detailed description of well-known matters or a redundant description of substantially the same configuration may be omitted. Note that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0011] [Beauty instrument] FIG. 1 is a perspective view of an example of a beauty instrument according to the first embodiment. FIG. 2 is a perspective view of a part of the beauty instrument according to the first embodiment as viewed from the head portion side. FIG. 3 is a plan view of a part of the beauty instrument according to the first embodiment as viewed from the back side. FIG. 4 is a plan view showing the electrode shape of the head portion of the beauty instrument according to the first embodiment.

[0012] As shown in FIG. 1, the beauty instrument 1A (1) includes a main body portion 10 that is held by a user, and a head portion 30A (30) that can energize a current having different characteristics to the skin of the user. The beauty instrument 1A is used such that, during treatment, the user holds the main body portion 10 and brings the head portion 30A into contact with the skin of the user.

[0013] (Main body portion) As shown in FIG. 1, the main body portion 10 is a columnar housing having a longitudinal direction in which the bottom portion 11 and the top portion 16 provided with the head portion 30A are connected, and having the bottom portion 11, the top portion 16, the front portion 12, the side portions 13, 15, and the back portion 14. The top portion 16 provided with the head portion 30 is lower in height on the front portion 12 side than on the back portion 14 side, so that when the user holds the main body portion 10 during treatment, it is easier to bring the head portion 30A into contact with the skin of the user.

[0014] Here, the front portion 12 is a portion that faces the user side when the user holds the main body portion 10 during treatment. The back portion 14 is a portion on the back side of the front portion 12. When the user holds the main body portion 10 during treatment, usually, the fingers other than the palm and thumb of the user contact the back portion 14, and it becomes easier for the thumb of the user to contact the front portion 12.

[0015] The front panel 12 is equipped with a power / mode switch 18 for turning the power on / off and switching between operating modes, and a level switch 17 for adjusting the current level. The operating modes will be described in detail later, but examples include wave lift mode, RF treatment mode, moisturizing mode, and eye care mode. These modes are set based on the frequency of the current applied to the user's skin and the combination of currents applied.

[0016] Each operating mode is set by combining, for example, the application of the voltage of one or more outputs, such as the first, second, and third outputs with different frequencies described later, between the electrodes, with LED light irradiation. Specifically, in wavelift mode, for example, the voltage of the second output is applied between the electrodes in the preceding stage and the voltage of the first output is applied in the succeeding stage within a unit time, and LED light irradiation is performed for the entire unit time. In this way, when voltages of outputs with different frequencies are applied at different time points within a unit time, it becomes possible to apply voltages of outputs with different frequencies to the same electrode 50. Therefore, when voltages of outputs with different frequencies are applied at different time points within a unit time, it becomes possible to reduce the number of electrodes 50 provided on the head unit 30A and miniaturize the head unit 30A.

[0017] The current that flows through the user's skin is generated by passing currents with different characteristics through a parallel electrode group 40, which is a collection of three or more electrodes 50 arranged in parallel on the head unit 30A. Voltages such as a first output with a first frequency, a second output with a second frequency lower than the first frequency, and a third output with a third frequency lower than the first frequency are applied to the parallel electrode group 40, as described later. Here, the first, second, and third outputs will be briefly explained. However, more details will follow later.

[0018] The first output is a high-frequency current output, and is the main output with a high output time ratio, for example, in RF treatment mode. As described later, RF treatment mode is a mode that generates Joule heat inside the skin by passing a high-frequency current through the skin. RF treatment mode aims to provide the user with effects such as skin lifting and improvement of skin dullness by promoting the production of collagen and other substances inside the skin and increasing capillary blood flow through the generated Joule heat.

[0019] The output time ratio refers to the ratio of the output time for each output when one cycle of the output in the operating mode sequentially performs one or more outputs selected from the first, second, and third outputs. For example, if one cycle of the RF treatment mode output consists of the first output for 208ms, a blank (no output) for 5ms, the third output for 32ms, and a blank (no output) for 5ms, the output time ratio for the first output is 208 / 250.

[0020] The second output is a relatively low-frequency current output, which is used, for example, in WaveLift mode. As described later, WaveLift mode is a mode that primarily aims to achieve firmer skin by applying this current to the user's skin and causing the facial muscles to vibrate through electrical stimulation.

[0021] The third output is a medium-frequency current output, which has a high output time ratio in modes such as moisturizing mode and eye care mode. As described below, the moisturizing mode is a mode that primarily aims to enhance the beauty effects of beauty ingredients by applying this current to the user's skin and allowing beauty ingredients to penetrate deep into the stratum corneum. The eye care mode is a mode that primarily aims to enhance the beauty effects of beauty ingredients by applying this current to the skin around the user's eyes and allowing beauty ingredients for the eye area to penetrate deep into the stratum corneum, as well as providing a warming sensation to the eye area.

[0022] The Wavelift mode is set to use, for example, a combination of the second output, the first output, and the LED light irradiation described later. The RF Treatment mode is set to use, for example, a combination of the first output, the third output, and the LED light irradiation. The Moisturizing mode is set to use, for example, a combination of the third output, the first output, and the LED light irradiation at a different output time ratio than the RF Treatment mode. The Eye Care mode is set to use, for example, a combination of the third output, the first output, and the LED light irradiation at a different output time ratio than the RF Treatment mode and the Moisturizing mode. The amount of LED light irradiation in Eye Care mode is, for example, less than the amount of LED light irradiation in Moisturizing mode.

[0023] The first and second outputs are transmitted to the user's skin by applying a voltage between multiple electrodes 50 provided on the head unit 30. The third output is transmitted to the user's skin by applying a voltage between one or more electrodes 50 provided on the head unit 30A and one or more electrodes 50 (body electrodes 20) provided on the main body unit 10 that is held by the user.

[0024] As shown in Figure 3, a main body electrode 20 is provided on the back surface 14 of the main body 10. Therefore, the main body 10 has a main body electrode 20 consisting of one or more electrodes 50 that come into contact with the user when the user grips it. The main body electrode 20 shown in Figure 3 consists of one oval-shaped electrode 50. However, the main body electrode 20 may consist of two or more electrodes 50. In other words, the main body electrode 20 can be a main body electrode 20 consisting of one or more electrodes 50.

[0025] The main electrode 20 is capable of conducting electricity with the electrode 50 provided on the head unit 30A. Specifically, an output voltage, such as a third output, is applied between at least some of the electrodes constituting the parallel electrode group 40 of the head unit 30A and the main electrode 20 of the main unit 10.

[0026] Furthermore, when the third output voltage is applied between the parallel electrode group 40 and the main electrode 20, it is preferable that all electrodes on the parallel electrode group 40 side are of the same polarity, and that the voltage is applied so that the electrodes on the parallel electrode group 40 side and the main electrode 20 side are of opposite polarity. Specifically, it is preferable that all electrodes of the parallel electrode group 40 to which the third output voltage is applied are of the same polarity, and that the electrodes of the parallel electrode group 40 to which the third output voltage is applied and the main electrode 20 side are of opposite polarity. Applying the third output voltage between the parallel electrode group 40 and the main electrode 20 in this manner is preferable because it increases the efficiency of iontophoresis of beauty ingredients.

[0027] (Head section) As shown in Figures 1 and 2, the head portion 30A is provided on a part of the main body portion 10. The head portion 30A has multiple electrodes 50 on the surface 32 of the head portion, and it is possible to pass currents with different characteristics to the user's skin via the electrodes 50.

[0028] As shown in Figure 1, the head portion 30A has a parallel electrode group 40, which is an assembly of three or more electrodes 50 arranged in parallel. Also, as shown in Figure 2, multiple LED lights 35 are provided on the head portion surface 32 between adjacent electrodes 50, 50 of the four electrodes 61(50), 75A(50), 75B(50), and 69(50) that constitute the parallel electrode group 40. For example, if a translucent head portion surface 32 is used as the head portion surface 32 and the LED lights 35 are embedded on the back side of the head portion surface 32, the LED lights 35 can be made visible only when they are lit.

[0029] In the head section 30A, the LED lights 35 are arranged in three rows of five. Specifically, a group of five LED lights 35 is provided in each row between the upper electrode 61 and the intermediate electrode 75A, between the intermediate electrodes 75A and 75B, and between the intermediate electrode 75B and the lower electrode 69. The number of rows of LED lights 35 and the number of LEDs per row are not particularly limited and can be changed as appropriate.

[0030] The three rows of LED lights 35 in the head unit 30A can be independently switched on and off, one row at a time, in sets of five. The head unit 30A allows for, for example, illuminating all three rows of LED lights 35, or illuminating only one row.

[0031] For example, a red LED light can be used as the LED light 35. When red LED light is shone on the skin, it can, for example, promote the repair of skin cells and blood circulation, and soothe skin inflammation and redness. The LED light 35 can be turned on in conjunction with the usage mode, such as the wave lift mode.

[0032] <Parallel electrode group> The electrodes 50 constituting the parallel electrode group 40 include an upper electrode 61, a lower electrode 69, and an intermediate electrode group 70 which is an assembly of intermediate electrodes 75A, 75B (75). Here, the upper electrode 61 is the electrode 50 that is positioned furthest from the bottom 11 of the main body 10 in the head portion 30A. The lower electrode 69 is the electrode 50 that is positioned closest to the bottom 11 of the main body 10 in the head portion 30A. Furthermore, the intermediate electrode group 70 is an assembly of one or more intermediate electrodes 75 which are electrodes 50 positioned between the upper electrode 61 and the lower electrode 69.

[0033] The electrodes 50 constituting the parallel electrode group 40 are arranged such that their electrode extension direction E intersects with the electrode parallel direction P of the parallel electrode group 40. Here, the intersection of the electrode extension direction E and the electrode parallel direction P means that when the electrode extension direction E and the electrode parallel direction P are projected onto the head surface 32 of the head part 30A, the projected electrode extension direction E and the electrode parallel direction P intersect.

[0034] The electrode parallel direction P is the direction in which each electrode 50 constituting the parallel electrode group 40 is arranged in parallel. In the head section 30A shown in Figure 4, the upper electrode 61, intermediate electrode 75A, intermediate electrode 75B, and lower electrode 69 are arranged in parallel in the vertical direction in Figure 4. Therefore, the electrode parallel direction P of the parallel electrode group 40 is the vertical direction in Figure 4.

[0035] Furthermore, the electrode extension direction E is the direction in which each electrode 50 constituting the parallel electrode group 40 is extended. Here, the direction in which the electrodes 50 are extended means the direction of extension of the curve or straight line formed in a plan view of the head portion 30A by the adjacent end 52 of electrode 50X(50) that is opposite to an adjacent electrode 50Y(50). Note that the plan view of the head portion 30A means viewing the head portion 30A from a direction perpendicular to the head portion surface 32 of the head portion 30A.

[0036] For example, the electrode extension direction E of the upper electrode 61 is the extension direction of the curve formed in a plan view of the head portion 30A by the arc-shaped adjacent end 52A2 (52, 56) of the upper electrode 61 that faces the adjacent intermediate electrode 75A. Hereinafter, the arc-shaped adjacent end 52A2 of the upper electrode 61 will also be referred to as the arc-shaped end 56.

[0037] The electrode extension direction E of the intermediate electrode 75A is the extension direction of the curve formed in a plan view of the head portion 30A by the arc-shaped adjacent end portions 52B1(52) and 52B2(52) of the intermediate electrode 75A that are opposite to the adjacent lower electrode 69 and intermediate electrode 75B, respectively. In the case of an intermediate electrode 75A, where there are two or more adjacent electrodes 50, the electrode extension direction E is determined for each adjacent end portion 52 that is opposite to an adjacent electrode 50, and each of these is designated as the electrode extension direction E.

[0038] For example, in the intermediate electrode 75A, the electrode extension direction E is determined based on the extension direction of the curve formed by each of the arc-shaped adjacent end portions 52B1 and 52B2 in a plan view of the head portion 30A, and these are designated as the electrode extension direction E. Since the curvature of the arc-shaped adjacent end portions 52B1 and 52B2 is the same, the electrode extension direction E of the intermediate electrode 75A is the same.

[0039] The electrode extension direction E of the intermediate electrode 75B is the extension direction of the curve formed in a plan view of the head portion 30A by the arc-shaped adjacent end portions 52C1(52) and 52C2(52) of the intermediate electrode 75B that are opposite the adjacent intermediate electrode 75A and the lower electrode 69, respectively. Since the curvature of the arc-shaped adjacent end portions 52C1 and 52C2 is the same, the electrode extension direction E of the intermediate electrode 75B is the same.

[0040] The electrode extension direction E of the lower electrode 69 is the extension direction of the curve formed in a plan view of the head portion 30A by the arc-shaped adjacent end portion 52D1(52) of the lower electrode 69 that faces the adjacent intermediate electrode 75B.

[0041] As described above, the electrodes 50 constituting the parallel electrode group 40, namely the upper electrode 61, intermediate electrode 75A, intermediate electrode 75B, and lower electrode 69, are arranged such that the electrode extension direction E of each electrode 50 intersects with the electrode parallel direction P of the parallel electrode group 40. Arranging the electrodes 50 constituting the parallel electrode group 40 so that the electrode extension direction E intersects with the electrode parallel direction P is preferable because it makes it easier to apply electrical stimulation to the skin substantially uniformly, regardless of the treatment direction. <Plan view shape of the upper electrode> Next, the plan view shapes of the upper electrode 61, intermediate electrode 75A, intermediate electrode 75B, and lower electrode 69 that constitute the parallel electrode group 40 will be described.

[0042] The upper electrode 61 has a roughly D-shape in plan view, including a straight end 55 and an arc-shaped end 56 (adjacent end 52A2) which is the end opposite to the straight end 55. The straight end 55 is positioned close to the straight upper outer edge 33, which is the straight end furthest from the bottom 11 of the main body 10 in the head portion 30A.

[0043] Having a roughly D-shaped straight end 55 in plan view of the upper electrode 61 is preferable because it makes it easier to lift sagging skin when the treatment direction is upward. Furthermore, having a roughly D-shaped plan view of the upper electrode 61 makes it easier to increase the electrode area of ​​the upper electrode 61, which makes it less likely for heat and current to concentrate in one place during treatment, thus making it easier to obtain a uniform and high cosmetic effect.

[0044] <Plan view shape of the intermediate electrode> The plan view shape of the intermediate electrode 75A is a curved shape having a curved shape in a portion that is approximately equal in width. Specifically, the plan view shape of the intermediate electrode 75A includes an arc-shaped adjacent direction end 52B1 (52) and an arc-shaped adjacent direction end 52B2 (52), which is the end opposite to the adjacent direction end 52B1. Since the curvature of the arc-shaped adjacent direction ends 52B1 and 52B2 is approximately the same, the plan view shape of the intermediate electrode 75A is a curved shape having a curved shape in a portion that is approximately equal in width.

[0045] The plan view shape of the intermediate electrode 75B is a curved shape, similar to that of the intermediate electrode 75A, with a curved shape in a portion of approximately equal width. Specifically, the plan view shape of the intermediate electrode 75B includes an arc-shaped adjacent direction end 52C1 (52) and an arc-shaped adjacent direction end 52C2 (52), which is the end opposite to the adjacent direction end 52C1. Since the curvature of the arc-shaped adjacent direction ends 52C1 and 52C2 is approximately the same, the plan view shape of the intermediate electrode 75B is a curved shape with a curved shape in a portion of approximately equal width.

[0046] Having a curved shape in plan view of the intermediate electrodes 75A and 75B is preferable because it makes it easier to apply electrical stimulation to the skin in a nearly uniform manner, regardless of the direction of treatment.

[0047] Furthermore, the curvature of the arc-shaped adjacent end 52B1 of the intermediate electrode 75A is approximately the same as the curvature of the arc-shaped end 56 (adjacent end 52A2) of the upper electrode 61. In addition, the arc-shaped adjacent end 52B1 of the intermediate electrode 75A and the arc-shaped end 56 (adjacent end 52A2) of the upper electrode 61 are arranged to be approximately equal in distance from each other. For this reason, in the beauty device 1A, when current is passed between the upper electrode 61 and the intermediate electrode 75A, it is preferable because it is easy to apply electrical stimulation to the skin approximately uniformly.

[0048] Furthermore, the curvature of the arc-shaped adjacent end 52C1 of the intermediate electrode 75B is approximately the same as the curvature of the arc-shaped adjacent end 52B2 of the intermediate electrode 75A. In addition, the arc-shaped adjacent end 52C1 of the intermediate electrode 75B and the arc-shaped adjacent end 52B2 of the intermediate electrode 75A are arranged to be approximately equal in distance from each other. For this reason, in the beauty device 1A, when current is passed between the intermediate electrode 75A and the intermediate electrode 75B, it is preferable because it is easy to apply electrical stimulation to the skin approximately uniformly.

[0049] Furthermore, the curvature of the arc-shaped adjacent end 52C2 of the intermediate electrode 75B is approximately the same as the curvature of the arc-shaped adjacent end 52D1 of the lower electrode 69. Also, the arc-shaped adjacent end 52C2 of the intermediate electrode 75B and the arc-shaped adjacent end 52D1 of the lower electrode 69 are arranged to be approximately equal in distance from each other. For this reason, in the beauty device 1A, when current is passed between the intermediate electrode 75B and the lower electrode 69, it is preferable because it is easy to apply electrical stimulation to the skin approximately uniformly.

[0050] <Plan view shape of the lower electrode> The plan view shape of the lower electrode 69 is a bent shape having a non-equal width portion that is bent. Specifically, the plan view shape of the lower electrode 69 includes an arc-shaped adjacent-direction end 52D1 (52) and an arc-shaped lowest end 59 which is the end opposite to the adjacent-direction end 52D1. Because the curvature of the arc-shaped adjacent-direction end 52D1 is smaller than the curvature of the lowest end 59, the plan view shape of the lower electrode 69 is a bent shape having a non-equal width portion that is bent, specifically a crescent shape.

[0051] Having a curved shape in plan view of the lower electrode 69 is preferable because it makes it easier to increase the electrode area of ​​the lower electrode 69, which prevents heat and current from concentrating in one place during treatment, thus making it easier to obtain a uniform and high cosmetic effect.

[0052] Furthermore, the plan view shape of the lower electrode 69 can be, if necessary, a curved shape having a substantially equal-width portion that is curved, similar to the plan view shapes of the intermediate electrodes 75A and 75B.

[0053] Furthermore, the plan view shapes of the intermediate electrodes 75A and 75B can be, if necessary, be bent, with non-equal width portions bent, similar to the plan view shape of the lower electrode 69.

[0054] <Electrode area> It is preferable that the upper electrode 61 and lower electrode 69 have a larger electrode area than the intermediate electrode 75 that constitutes the intermediate electrode group 70, as this makes it less likely for heat and current to concentrate in one place during treatment, thus making it easier to obtain a uniform and high cosmetic effect. For example, in the case of EMS treatment, a voltage of a second output having a second frequency, as described later, is often applied to the pair of electrodes 89, which consists of the pair of electrodes 50 at both ends of the upper electrode 61 and lower electrode 69, among the electrodes 50 that constitute the parallel electrode group 40. In this case, it is preferable that the upper electrode 61 and lower electrode 69 have a larger electrode area than the intermediate electrode 75 that constitutes the intermediate electrode group 70, as this makes it less likely for heat and current to concentrate in one place during EMS treatment, thus making it easier to obtain a uniform and high skin lifting effect.

[0055] As shown in Figure 4, the parallel electrode group 40 is aligned such that the distance between adjacent electrodes 50 constituting the parallel electrode group 40 is constant in at least a portion of the electrode extension direction E of the electrodes 50. Aligning the electrodes 50 constituting the parallel electrode group 40 is preferable because it makes it easier to apply electrical stimulation to the skin substantially uniformly, regardless of the treatment direction.

[0056] The distance between adjacent electrodes, between the upper electrode 61 and the intermediate electrode 75A adjacent to the upper electrode 61, is constant in at least a portion of the electrode extension direction E shown in Figure 4. Therefore, the upper electrode 61 and the intermediate electrode 75A are aligned.

[0057] The distance between adjacent intermediate electrodes 75A and 75B is constant in at least a portion of the electrode extension direction E shown in Figure 4. Therefore, intermediate electrodes 75A and 75B are aligned.

[0058] The distance between the lower electrode 69 and the adjacent intermediate electrode 75B is constant in at least a portion of the electrode extension direction E shown in Figure 4. Therefore, the intermediate electrode 75B and the lower electrode 69 are aligned.

[0059] Figure 5 shows an example of the electrical connection of the head portion of the beauty device according to the first embodiment. As shown in Figure 5, the parallel electrode group 40 of the head portion 30A is electrically connected to the EMS electrode control unit 151, the RF electrode control unit 152, and the IP electrode control unit 153. The parallel electrode group 40 is configured so that a voltage of a specific output can be applied between specific electrodes 50 by the EMS electrode control unit 151, the RF electrode control unit 152, and the IP electrode control unit 153.

[0060] The EMS electrode control unit 151 is a unit that controls outputs such as a second output that applies a voltage between the upper electrode 61 and the lower electrode 69. The RF electrode control unit 152 is a unit that controls outputs such as a first output that applies a voltage between the upper electrode 61 and the intermediate electrode 75A, and between the intermediate electrode 75B and the lower electrode 69. The IP electrode control unit 153 is a unit that controls outputs such as a third output that applies a voltage between each electrode 50 constituting the parallel electrode group 40 of the head unit 30A and the main body electrode 20 of the main body unit 10.

[0061] The parallel electrode group 40 and the main electrode 20 are electrically connected to the EMS electrode control unit 151, the RF electrode control unit 152, and the IP electrode control unit 153 by conductors 111, 121, 131, etc.

[0062] <First output, second output, and third output> The first, second, and third outputs, to which voltages are applied between the electrodes 50 constituting the parallel electrode group 40, or between the electrodes 50 constituting the parallel electrode group 40 and the main electrode 20 (50), will be described.

[0063] The first output is a high-frequency current output having a first frequency, which is typically referred to as a radio frequency (RF) output. The first output is typically used in RF treatments. For example, the first frequency is within the range of 1MHz to 5MHz, preferably 2.5MHz to 3.5MHz. The first output generates Joule heat within the skin by passing a high-frequency current through the skin, thereby promoting the production of collagen and other substances within the skin, as well as increasing capillary blood flow, resulting in effects such as skin lifting and improvement of skin dullness. For example, in RF treatment mode, the first output is used together with the third output, and the output time ratio is higher than that of the third output.

[0064] The first output is preferable because, when a voltage is applied between a relatively close pair of electrodes 50, 50 among the electrodes 50 constituting the parallel electrode group 40, it is easier to obtain moisturized, smooth, and bright skin by allowing moisturizing ingredients to penetrate deep into the stratum corneum. Furthermore, it is preferable because applying a voltage in this manner tends to increase the effect of generating a warming sensation in the user.

[0065] The second output is a relatively low-frequency current output having a second frequency, which is typically a current output at a frequency used in EMS (Electrical Muscle Stimulation). For example, the second frequency is within the range of 1Hz to 10kHz, preferably 5Hz to 2.5kHz. The second output has the effect of tightening the skin by, for example, applying the current to the user's skin to electrically stimulate and vibrate the facial muscles. The second output is used, for example, in WaveLift mode, in conjunction with the first output, and is used at a lower output time ratio than the first output.

[0066] The second output is preferable because applying a voltage between a relatively distant pair of electrodes 50, 50 among the electrodes 50 that make up the parallel electrode group 40 tends to enhance the effect of obtaining firmer skin by electrically stimulating and vibrating the facial muscles. This is because it is presumed that the greater the distance between the electrodes 50, 50 to which the voltage of the second output is applied, the more deeply and widely the facial muscles in the skin can be vibrated by electrical stimulation.

[0067] The third output is a medium-frequency current output having a third frequency lower than the first frequency, and is typically a current output at a frequency used in IP (Iontophoresis). For example, the third frequency is in the range of 1kHz to 10kHz, preferably 1kHz to 2kHz. The third output has the effect of enhancing the beauty effects of beauty ingredients by, for example, applying the current to the user's skin to penetrate the beauty ingredients deep into the stratum corneum. The third output is used together with the first output in, for example, the moisturizing mode and eye care mode, and is used at an output time ratio similar to that of the first output.

[0068] The third output is preferable because applying a voltage between each electrode 50 constituting the parallel electrode group 40 and the main electrode 20 increases the efficiency of iontophoresis of beauty ingredients.

[0069] Preferably, the first, second, and third outputs described above are obtained by applying a voltage between a specific combination of electrodes 50 from among the electrodes 50 constituting the parallel electrode group 40 and the main body electrode 20(50). Note that a voltage different from the first and second outputs may be applied between the electrodes 50 constituting the parallel electrode group 40.

[0070] The intermediate output is the output of a current having an intermediate frequency lower than the first frequency and higher than the second frequency. The intermediate frequency is not particularly limited.

[0071] <First output, second output, intermediate output, and energizing electrodes> The first output, the second output, and the intermediate output are obtained by applying a voltage between the electrodes 50 that constitute the parallel electrode group 40.

[0072] In the parallel electrode group 40, it is preferable that the first output voltage is applied between the proximity electrode pair 83, which consists of a pair of electrodes 50 that are closer together than the end electrode pair 89, which consists of a pair of electrodes 50 at both ends of the upper electrode 61 and the lower electrode 69. In this case, the first frequency is preferably 1 MHz to 5 MHz, as described above.

[0073] The pair of electrodes 89 at both ends and the pair of proximity electrodes 83 will be explained with reference to the drawings. Figure 6 is a plan view illustrating the combination of proximity electrode pairs. In the head portion 30 shown in Figure 6, the pair of electrodes 89 at both ends consists of an upper electrode 61 and a lower electrode 69. In the head portion 30 shown in Figure 6, the pair of proximity electrodes 83, which consists of a pair of electrodes 50 that are closer than the pair of electrodes 89 at both ends, consists of five combinations of proximity electrode pairs 83A, 83B, 83C, 83D, and 83E (83) shown on the right side of Figure 6. When the voltage of the first output is applied between the proximity electrode pairs 83 in the parallel electrode group 40, it is preferable because the beauty effect of the first output tends to be higher.

[0074] In the parallel electrode group 40, it is preferable that a second output voltage having a second frequency is applied between a pair of remote electrodes 87, which consists of a pair of electrodes 50 located further away than the adjacent electrode pair 83. It is even more preferable that the remote electrode pair 87 includes the upper electrode 61. In these cases, the second frequency is preferably 1 Hz to 10 kHz, as described above.

[0075] The pair of electrodes 89 at both ends, the pair of nearby electrodes 83, and the pair of far electrodes 87 will be explained with reference to the drawings. Figure 7 is a plan view illustrating the combination of the pair of nearby electrodes and the combination of the pair of far electrodes including the pair of electrodes at both ends. In the parallel electrode group 40 shown in Figure 7, the pair of electrodes 89 at both ends consists of an upper electrode 61 and a lower electrode 69, similar to the parallel electrode group 40 shown in Figure 6. In addition, the parallel electrode group 40 shown in Figure 7 further includes a pair of far electrodes 87 consisting of a pair of electrodes 50 that are further away from the pair of nearby electrodes 83, in addition to the pair of nearby electrodes 83.

[0076] The combinations of the end electrode pair 89, the nearby electrode pair 83, and the far electrode pair 87 in the parallel electrode group 40 shown in Figure 7 are as shown in Figure 7. Specifically, the nearby electrode pair 83 is a combination of three nearby electrode pairs 83A, 83B, and 83C(83) shown on the right side of Figure 7. The far electrode pair 87 is a combination of three electrodes 87B, 87C(87), and the end electrode pair 89 shown on the right side of Figure 7. The electrode pair consisting of the upper electrode 61 and the lower electrode 69 is the end electrode pair 89, but in consideration of its relationship with the nearby electrode pair 83, it is also the far electrode pair 87. When a second output voltage is applied between the far electrode pair 87 in the parallel electrode group 40, the beauty effect from the second output tends to be higher, which is preferable.

[0077] [Example 1] Figure 8 is a plan view showing a first example of a combination of electrode pairs that conduct electricity. In the parallel electrode group 40 shown in Figure 8, the electrode pair consisting of the upper electrode 61 and the lower electrode 69 is the end electrode pair 89 (far electrode pair 87), and the electrode pair consisting of the intermediate electrode 75A and the intermediate electrode 75B is the nearby electrode pair 83B.

[0078] In the first example shown in Figure 8, for example, the voltage of the second output is applied to the pair of electrodes 89 (the pair of distant electrodes 87), and the voltage of the first output is applied to the pair of nearby electrodes 83B. The voltages of the second output and the first output are usually applied at different times. For example, the first output and the second output are output alternately at different times. It is preferable that the voltages are applied alternately at different times, as this allows the voltage to be applied to the same electrode, for example, by reducing the number of electrodes 50 and thus the size of the head unit 30. It is also preferable that the application time of the first output is longer than that of the second output, as this prolongs the skin warming effect of the first output and tends to reduce wrinkles and sagging of the skin.

[0079] [Second example] Figure 9 is a plan view showing a second example of a combination of electrode pairs that conduct electricity. In the parallel electrode group 40 shown in Figure 9, the electrode pair consisting of the upper electrode 61 and the lower electrode 69 is the end electrode pair 89 (far electrode pair 87), and the electrode pair consisting of the upper electrode 61 and the intermediate electrode 75A is the nearby electrode pair 83A.

[0080] In the second example shown in Figure 9, for example, the voltage of the second output is applied to the pair of electrodes 89 (the pair of distant electrodes 87), and the voltage of the first output is applied to the pair of nearby electrodes 83A. However, the application of the voltages of the second output and the first output is performed at different times. For example, the first output and the second output are output alternately at different times. It is preferable that the voltages are applied alternately at different times, as this allows the voltage to be applied to the same electrode, for example, by reducing the number of electrodes 50 and thus reducing the size of the head unit 30. Furthermore, it is preferable that the application time of the first output is longer than that of the second output, as this prolongs the skin warming effect of the first output, which tends to reduce wrinkles and sagging of the skin.

[0081] In the second example shown in Figure 9, when the second output and the first output are applied in this manner, the upper electrode 61 is used in common for both the application of the second output and the first output voltage. It is preferable that at least one electrode 50 among the electrodes 50 constituting the parallel electrode group 40 is a common electrode 50 to which voltages of outputs with different frequencies are applied, for example, because the number of electrodes 50 can be reduced and the head portion 30 can be made smaller.

[0082] Note that the second example shown in Figure 9, which has electrodes 50 to which voltage is applied in common, and the first example shown in Figure 8, which does not have electrodes 50 to which voltage is applied in common, have the same number of electrodes 50 in the parallel electrode group 40. However, the second example shown in Figure 9 is preferable to the first example shown in Figure 8 because, since the electrode area is large and voltage can be applied to the upper electrode 61 of a specific shape, heat and current are less likely to concentrate in one place during treatment, making it easier to obtain a uniform and high cosmetic effect.

[0083] [Third example] Figure 10 is a plan view showing a third example of a combination of electrode pairs that conduct electricity. In the parallel electrode group 40 shown in Figure 10, the electrode pair consisting of the upper electrode 61 and the lower electrode 69 is the end electrode pair 89 (far electrode pair 87), and the electrode pair consisting of the upper electrode 61 and the intermediate electrode 75B is the nearby electrode pair 83D.

[0084] In the third example shown in Figure 10, for example, the voltage of the second output is applied to the pair of electrodes 89 (the pair of distant electrodes 87), and the voltage of the first output is applied to the pair of nearby electrodes 83D. However, the application of the voltages of the second output and the first output is performed at different times. For example, the first output and the second output are output alternately at different times. It is preferable that the voltages are applied alternately at different times, as this allows the voltage to be applied to the same electrode, for example, by reducing the number of electrodes 50 and thus the size of the head unit 30. Furthermore, it is preferable that the application time of the first output is longer than that of the second output, as this prolongs the skin warming effect of the first output, which tends to reduce wrinkles and sagging of the skin.

[0085] In the third example shown in Figure 10, when the second output and the first output are applied in this manner, the upper electrode 61 is used in common regardless of whether the voltage of the second output or the first output is applied.

[0086] In this way, it is preferable that at least one of the electrodes 50 constituting the parallel electrode group 40 is a common electrode 50 to which an output voltage having a different frequency is applied, because for example, the number of electrodes 50 can be reduced and the head portion 30 can be made smaller.

[0087] Note that the third example shown in Figure 10, which has electrodes 50 to which voltage is applied in common, and the first example shown in Figure 8, which does not have electrodes 50 to which voltage is applied in common, have the same number of electrodes 50 in the parallel electrode group 40. However, the third example shown in Figure 10 is preferable to the first example shown in Figure 8 because, since the electrode area is large and voltage can be applied to the upper electrode 61 of a specific shape, heat and current are less likely to concentrate in one place during treatment, making it easier to obtain a uniform and high cosmetic effect.

[0088] [Fourth example] Figure 11 is a plan view showing a fourth example of a combination of energized electrode pairs. The parallel electrode group 40 shown in Figure 11 is an example in which an electrode pair consisting of an upper electrode 61 and a lower electrode 69 forms an end electrode pair 89 (long electrode pair 87), an electrode pair consisting of an intermediate electrode 75A and an intermediate electrode 75B forms a nearby electrode pair 83B, and there is also a medium-distance electrode pair 85.

[0089] Here, the intermediate-range electrode pair 85 refers to an electrode pair consisting of a pair of electrodes 50 that are further away than the proximity electrode pair 83 and closer than the distance electrode pair 87. In the example of the parallel electrode group 40 shown in Figure 11, the electrode pair consisting of the upper electrode 61 and the intermediate electrode 75B constitutes the intermediate-range electrode pair 85A (85). It is preferable that an intermediate output voltage having an intermediate frequency lower than the first frequency and higher than the second frequency is applied between the intermediate-range electrode pair 85. Applying an intermediate output voltage between the intermediate-range electrode pair 85 is preferable because, in addition to the first output (RF output) and the second output (EMS output), a beauty effect specific to the intermediate output can be expected.

[0090] In the fourth example shown in Figure 11, for example, the voltage of the second output is applied to the pair of electrodes 89 (the pair of distant electrodes 87), the voltage of the first output is applied to the pair of nearby electrodes 83B, and the voltage of the intermediate output is applied to the pair of medium-distance electrodes 85A. However, the voltages of the second output and the first output are applied at different times. Similarly, the voltages of the first output and the intermediate output are applied at different times.

[0091] In the fourth example shown in Figure 11, when the second output, first output, and intermediate output are applied in this manner, the upper electrode 61 is used in common with the application of voltages for both the second output and the first output. In this case, the intermediate electrode 75B is also used in common with the application of voltages for both the first output and the intermediate output.

[0092] In this way, it is preferable that at least one of the electrodes 50 constituting the parallel electrode group 40 is a common electrode 50 to which an output voltage having a different frequency is applied, because for example, the number of electrodes 50 can be reduced and the head portion 30 can be made smaller.

[0093] Note that the fourth example shown in Figure 11, which has electrodes 50 to which voltage is applied in common, and the first example shown in Figure 8, which does not have electrodes 50 to which voltage is applied in common, have the same number of electrodes 50 in the parallel electrode group 40. However, the fourth example shown in Figure 11 is preferable to the first example shown in Figure 8 because, since the electrode area is large and voltage can be applied to the upper electrode 61 of a specific shape, heat and current are less likely to concentrate in one place during treatment, making it easier to obtain a uniform and high cosmetic effect.

[0094] <Third output and current-carrying electrode> The third output is obtained by applying a voltage between the electrodes 50 constituting the parallel electrode group 40 and the main electrode 20(50). One or more of the electrodes 50 constituting the parallel electrode group 40 are used as the electrodes 50 constituting the parallel electrode group 40. In the parallel electrode group 40 shown in Figure 5, the X terminal of the IP electrode control unit 153 is connected to all of the upper electrode 61, intermediate electrode 75A, intermediate electrode 75B, and lower electrode 69. The Y terminal of the IP electrode control unit 153 is connected to the main electrode 20(50).

[0095] (Usage mode) The beauty device 1A has the electrode configuration described above, and depending on the mode of use during treatment, various output voltages are applied between the electrodes 50 constituting the parallel electrode group 40, and between the electrodes 50 constituting the parallel electrode group 40 and the main body electrode 20 (50), etc. Examples of usage modes include wave lift mode, RF treatment mode, moisturizing mode, eye care mode, etc.

[0096] Wavelift mode, RF treatment mode, moisturizing mode, and eye care mode are set by combining the application of voltage from one or more outputs of different frequencies (first, second, and third outputs) between the electrodes with LED light irradiation. Specifically, these modes are set by combining the application of voltage from one or more outputs of the first, second, and third outputs between the electrodes with LED light irradiation. Each usage mode is typically set to have different output levels and output time ratios for the first, second, and third outputs and LED light irradiation.

[0097] Table 1 shows examples of setting conditions for the Wave Lift mode, RF Treatment mode, Moisturizing mode, and Eye Care mode set on the beauty device 1A. Note that the usage modes shown in Table 1 are examples only, and the usage modes in this disclosure are not limited to those shown in Table 1. Each usage mode is switched and adjusted by operating the power / mode switch 18, level switch 17, etc.

[0098] [Table 1]

[0099] <Wave Lift Mode> WaveLift mode is a mode that combines, for example, a second output for EMS, a first output for RF treatment, and LED light irradiation. WaveLift mode is primarily intended to achieve firmer skin by applying electrical current to the user's skin and vibrating the facial muscles with electrical stimulation.

[0100] Figure 12 shows an example of an output pattern in wavelift mode. Figure 13 shows a detailed view of waveform A in Figure 12. Figure 14 shows the output pattern including the RF output in waveform A in Figure 13. Figure 15 shows a detailed view of waveform B in Figure 12. Figure 16 shows the output pattern including the RF output in waveform B in Figure 15. Note that the wavelift mode output patterns shown in Figures 12 to 16 are different examples from the wavelift mode output patterns shown in Table 1.

[0101] The output pattern of the wavelift mode shown in Figure 12 consists of repeating the output of waveform A for 200ms four times (waveform A group), repeating the output of waveform B for 40ms five times (waveform B group), and then alternating between the outputs of waveform A group and waveform B group.

[0102] The details of waveform A in Figure 12 are shown in Figure 13. Waveform A shown in Figure 13 consists of a first stage consisting of a pulse wave for EMS that inverts every 0.2 ms (EMS output, second output), and a second stage consisting of a blank (unpowered) portion, an RF output (first output) portion, and another blank (unpowered) portion.

[0103] The output pattern, including the subsequent RF output shown in Figure 13, specifically consists of a 26ms blank (unpowered) section, a 140ms RF output (first output) section, and a 26ms blank (unpowered) section, as shown in Figure 14.

[0104] The details of waveform B in Figure 12 are shown in Figure 15. Waveform B shown in Figure 15 consists of a first stage consisting of a pulse wave for EMS that inverts every 0.2 ms (EMS output, second output), and a second stage consisting of a blank (unpowered) portion, an RF output (first output) portion, and another blank (unpowered) portion.

[0105] The output pattern, including the subsequent RF output shown in Figure 15, specifically consists of a 5ms blank (unpowered) section, a 26ms RF output (first output) section, and a 5ms blank (unpowered) section, as shown in Figure 16.

[0106] The output pattern in WaveLift mode as shown in Figure 12 is preferable because the second output electrically stimulates the facial muscles to contract and relax, resulting in firmer skin, and the first output warms the skin, which tends to reduce wrinkles and sagging.

[0107] As shown in Table 1, in wavelift mode, for example, during the output of the output pattern shown in Figure 12, three rows of LED lights illuminate. Here, three rows of LED lights illuminating means that all three rows of LED lights are illuminated: one row between the upper electrode 61 and the intermediate electrode 75A, one row between the intermediate electrode 75A and the intermediate electrode 75B, and one row between the intermediate electrode 75B and the lower electrode 69.

[0108] The output time ratio for wavelift mode will now be explained. The wavelift mode output pattern shown in Figure 12 consists of a total unit of 1000ms (1s) per cycle, comprising Waveform A group, which repeats the output of Waveform A for 200ms four times, and Waveform B group, which repeats the output of Waveform B for 40ms five times.

[0109] In waveform A, shown in Figures 13 and 14, the EMS output (second output) portion is 8 ms, the RF output (first output) portion is 140 ms, and the blank portion is 52 ms. In waveform B, shown in Figures 15 and 16, the EMS output (second output) portion is 4 ms, the RF output (first output) portion is 26 ms, and the blank portion is 10 ms.

[0110] Therefore, in waveform A group, which repeats the output of waveform A four times for 800ms, the EMS output (second output) portion is 32ms, the RF output (first output) portion is 560ms, and the blank portion is 208ms. Similarly, in waveform B group, which repeats the output of waveform B five times for 200ms, the EMS output (second output) portion is 20ms, the RF output (first output) portion is 130ms, and the blank portion is 50ms.

[0111] Therefore, the output time ratio of the output pattern for one 1000ms (1s) cycle of the wavelift mode shown in Figure 12 is calculated as follows: The output time ratio of the EMS output (second output) portion is (32 + 20) / 1000 = 5.2%. The output time ratio of the RF output (first output) portion is (560 + 130) / 1000 = 69.0%. The output time ratio of the blank portion is (208 + 50) / 1000 = 25.8%.

[0112] Note that the output time ratios for the EMS output (second output), RF output (first output), and blank portion in Wavelift mode are not limited to the values ​​above. The output time ratio for the EMS output (second output) portion can be, for example, 2-10%. The output time ratio for the RF output (first output) portion can be, for example, 65-75%.

[0113] The wavelift mode is performed, for example, using the beauty device 1A shown in Figure 5. In the beauty device 1A shown in Figure 5, it is possible to apply the voltage of the EMS output (second output) between the upper electrode 61 and the lower electrode 69. In addition, in the beauty device 1A shown in Figure 5, it is possible to apply the voltage of the RF output (first output) between the upper electrode 61 and the intermediate electrode 75A, and between the intermediate electrode 75B and the lower electrode 69. Furthermore, in the beauty device 1A shown in Figure 5, it is possible to apply the voltage of the IP output (third output) between each electrode 50 constituting the parallel electrode group 40 of the head unit 30A and the main body electrode 20 of the main body unit 10.

[0114] Thus, in the beauty device 1A shown in Figure 5, the upper electrode 61 and the lower electrode 69 are electrodes that are used in common for both EMS output (second output) and RF output (first output), contributing to a reduction in the number of electrodes 50 that make up the parallel electrode group 40.

[0115] The pulse waves for EMS included in waveforms A and B are generated, for example, by applying a second output voltage for EMS between the upper electrode 61 and the lower electrode 69 by the EMS electrode control unit 151. The electrode pair consisting of the upper electrode 61 and the lower electrode 69 is a pair of electrodes 89 (a pair of electrodes 87).

[0116] Furthermore, the RF output portion included in waveforms A and B is generated, for example, by applying a first output voltage for RF output to at least one of the spaces between the upper electrode 61 and the intermediate electrode 75A, and between the intermediate electrode 75B and the lower electrode 69, by the RF electrode control unit 152. The electrode pair consisting of the upper electrode 61 and the intermediate electrode 75A is the proximity electrode pair 83A, and the electrode pair consisting of the intermediate electrode 75B and the lower electrode 69 is the proximity electrode pair 83C.

[0117] The three rows of LED lights can be switched and adjusted by selecting the wavelift mode using the power / mode switch 18, level switch 17, etc.

[0118] <RFトリートメント(RF TREATMENT)モード> The RF treatment mode is a mode that combines, for example, a first output for RF treatment, a third output for IP (iontophoresis), and LED light irradiation. The RF treatment mode primarily aims to provide moisturized, smooth, and bright skin by applying current to the user's skin to penetrate moisturizing ingredients deep into the stratum corneum, and also to produce a warming sensation in the user.

[0119] Figure 17 shows an example of an output pattern in RF treatment mode. Note that the output pattern in RF treatment mode shown in Figure 17 is a different example from the output pattern in RF treatment mode shown in Table 1. The output pattern in RF treatment mode shown in Figure 17 consists of a 208ms RF output (first output) portion, a 5ms blank (unpowered) portion, a 32ms IP output (third output) portion, and a 5ms blank (unpowered) portion.

[0120] The output pattern in RF treatment mode as shown in Figure 17 is preferable because the first output has a warming effect on the skin, which helps to reduce wrinkles and sagging, provides a pleasant warming sensation, and the third output allows moisturizing ingredients to penetrate deep into the stratum corneum.

[0121] As shown in Table 1, in RF treatment mode, for example, during the output of the output pattern shown in Figure 17, three rows of LED lights illuminate. Here, three rows of LED lights illuminating has the same meaning as three rows of LED lights illuminating in wavelift mode.

[0122] The output time ratios for the RF treatment mode are explained below. The output time ratios for the output patterns in RF treatment mode shown in Figure 17 are calculated as follows: The output time ratio for the RF output (first output) portion shown in Figure 17 is 208 / (208+5+32+5)=83.2%. The output time ratio for the IP output (third output) portion shown in Figure 17 is 32 / (208+5+32+5)=12.8%. The output time ratio for the blank portion shown in Figure 17 is 10 / (208+5+32+5)=4.0%.

[0123] Note that the output time ratios for the RF output (first output), IP output (third output), and blank portion in RF treatment mode are not limited to the values ​​above. The output time ratio for the RF output (first output) portion can be, for example, 75-95%. The output time ratio for the IP output (third output) portion can be, for example, 5-18%.

[0124] The RF treatment mode is performed, for example, using the beauty device 1A shown in Figure 5. As described above, in the beauty device 1A shown in Figure 5, the upper electrode 61 and the lower electrode 69 are electrodes that are used in common for the EMS output (second output) and the RF output (first output), contributing to a reduction in the number of electrodes 50 that make up the parallel electrode group 40. Furthermore, the upper electrode 61, intermediate electrode 75A, intermediate electrode 75B, and the lower electrode 69, which are electrodes 50 that make up the parallel electrode group 40, are also electrodes that are used in common for the IP output (third output), further contributing to a reduction in the number of electrodes 50 that make up the parallel electrode group 40.

[0125] The RF output portion shown in Figure 17 is generated, for example, by the RF electrode control unit 152 applying a first output voltage for RF output to at least one of the spaces between the upper electrode 61 and the intermediate electrode 75A, and between the intermediate electrode 75B and the lower electrode 69. The electrode pair consisting of the upper electrode 61 and the intermediate electrode 75A is the proximity electrode pair 83A, and the electrode pair consisting of the intermediate electrode 75B and the lower electrode 69 is the proximity electrode pair 83C.

[0126] Furthermore, the IP output portion shown in Figure 17 is generated, for example, by the IP electrode control unit 153 applying a third output voltage for IP output between the electrodes 50 constituting the parallel electrode group 40 of the head unit 30 and the main body electrode 20(50). Normally, current is supplied to all electrodes 50 constituting the parallel electrode group 40 of the head unit 30, but it may also be supplied to only some of the electrodes 50 constituting the parallel electrode group 40.

[0127] The three rows of LED lights can be switched and adjusted by selecting the wavelift mode using the power / mode switch 18, level switch 17, etc.

[0128] <Moisturizing Mode> The moisturizing mode is a mode that combines, for example, a first output for RF treatment, a third output for IP (iontophoresis), and LED light irradiation. The moisturizing mode primarily aims to enhance the beauty effects of beauty ingredients by applying the current to the user's skin to allow the beauty ingredients to penetrate deep into the stratum corneum.

[0129] Figure 18 shows an example of an output pattern in moisturizing mode. Note that the output pattern in moisturizing mode shown in Figure 18 is a different example from the output pattern in moisturizing mode shown in Table 1. The RF treatment mode output pattern shown in Figure 18 consists of a total of 144ms of IP output (third output), a 5ms blank (unpowered) portion, a 96ms of RF output (first output), and a 5ms blank (unpowered) portion.

[0130] The output pattern in moisturizing mode as shown in Figure 18 is preferable because the third output allows moisturizing ingredients to penetrate deeper into the skin than when applied by hand, thereby moisturizing the skin, while the first output provides a warming effect. Here, the effect of the third output allowing moisturizing ingredients to penetrate deeper into the skin than when applied by hand is achieved by the action of generating electroosmotic flow from the skin surface to the interior.

[0131] As shown in Table 1, in moisturizing mode, for example, during the output of the output pattern shown in Figure 18, three rows of LED lights illuminate. Here, three rows of LED lights illuminating has the same meaning as three rows of LED lights illuminating in wavelift mode.

[0132] The output time ratio for the moisturizing mode is explained below. The output time ratio for the output pattern in moisturizing mode shown in Figure 18 is calculated as follows: The output time ratio for the IP output (third output) portion shown in Figure 18 is 144 / (144+5+96+5)=57.6%. The output time ratio for the RF output (first output) portion shown in Figure 18 is 96 / (144+5+96+5)=38.4%. The output time ratio for the blank portion shown in Figure 18 is 10 / (144+5+96+5)=4.0%.

[0133] Furthermore, the output time ratios for the IP output (third output), RF output (first output), and blank portion in moisturizing mode are not limited to the values ​​mentioned above. The output time ratio for the IP output (third output) portion can be, for example, 40-65%. The output time ratio for the RF output (first output) portion can be, for example, 30-55%.

[0134] The moisturizing mode is performed, for example, using the beauty device 1A shown in Figure 5. As described above, in the beauty device 1A shown in Figure 5, the upper electrode 61 and the lower electrode 69 are electrodes that are used in common for the EMS output (second output) and RF output (first output), contributing to a reduction in the number of electrodes 50 that make up the parallel electrode group 40. Furthermore, the upper electrode 61, intermediate electrode 75A, intermediate electrode 75B, and the lower electrode 69, which are electrodes 50 that make up the parallel electrode group 40, are also electrodes that are used in common for the IP output (third output), further contributing to a reduction in the number of electrodes 50 that make up the parallel electrode group 40.

[0135] The IP output portion shown in Figure 18 is generated, for example, by the IP electrode control unit 153 applying a third output voltage for IP output between the electrodes 50 constituting the parallel electrode group 40 of the head unit 30 and the main body electrode 20(50). Normally, current is supplied to all electrodes 50 constituting the parallel electrode group 40 of the head unit 30, but it may also be supplied to only some of the electrodes 50 constituting the parallel electrode group 40.

[0136] Furthermore, the RF output portion shown in Figure 18 is generated, for example, by applying a first output voltage for RF output to at least one of the two points between the upper electrode 61 and the intermediate electrode 75A, and between the intermediate electrode 75B and the lower electrode 69, by the RF electrode control unit 152. The electrode pair consisting of the upper electrode 61 and the intermediate electrode 75A is the proximity electrode pair 83A, and the electrode pair consisting of the intermediate electrode 75B and the lower electrode 69 is the proximity electrode pair 83C.

[0137] The three rows of LED lights can be switched and adjusted by selecting the wavelift mode using the power / mode switch 18, level switch 17, etc.

[0138] <Eye Care Mode> The eye care mode is a mode that combines, for example, a first output for RF treatment, a third output for IP (iontophoresis), and LED light irradiation. The eye care mode primarily aims to enhance the beauty effects of beauty ingredients by applying the current to the skin around the user's eyes, allowing the beauty ingredients to penetrate deep into the stratum corneum, and also to provide a warming sensation to the eye area. In eye care mode, the amount of LED light irradiation is usually reduced compared to other modes such as moisturizing mode.

[0139] Figure 19 shows an example of an output pattern in eye care mode. Note that the output pattern in eye care mode shown in Figure 19 is a different example from the output pattern in eye care mode shown in Table 1. The RF treatment mode output pattern shown in Figure 19 consists of a total of 160ms of IP output (third output), a 5ms blank (unpowered) portion, an 80ms of RF output (first output), and a 5ms blank (unpowered) portion.

[0140] The output pattern in eye care mode as shown in Figure 19 is preferable because the first output provides optimal warmth to the delicate skin around the eyes, reducing wrinkles and dark circles, and allowing beauty ingredients for the eye area to penetrate the skin.

[0141] As shown in Table 1, in eye care mode, for example, during the output of the output pattern shown in Figure 19, one row of LED lights illuminates. When one row of LED lights illuminates, it means that one of the following is illuminated: the row of LED lights between the upper electrode 61 and the intermediate electrode 75A, the row of LED lights between the intermediate electrode 75A and the intermediate electrode 75B, or the row of LED lights between the intermediate electrode 75B and the lower electrode 69. Of these, it is preferable when the row of LED lights between the upper electrode 61 and the intermediate electrode 75A is illuminated, as this makes it easier for the user to identify the area to apply to the eyes, and also allows for power saving.

[0142] The output time ratios for the eye care mode are explained below. The output time ratios for the output patterns in eye care mode shown in Figure 19 are calculated as follows: The output time ratio for the IP output (third output) portion shown in Figure 19 is 160 / (160+5+80+5)=64.0%. The output time ratio for the RF output (first output) portion shown in Figure 19 is 80 / (160+5+80+5)=32.0%. The output time ratio for the blank portion shown in Figure 19 is 10 / (160+5+80+5)=4.0%.

[0143] Note that the output time ratios for the IP output (third output), RF output (first output), and blank portion in eye care mode are not limited to the values ​​above. The output time ratio for the IP output (third output) can be, for example, 40-70%. The output time ratio for the RF output (first output) can be, for example, 25-55%.

[0144] The eye care mode is performed, for example, using the beauty device 1A shown in Figure 5. As described above, in the beauty device 1A shown in Figure 5, the upper electrode 61 and the lower electrode 69 are electrodes that are used in common for the EMS output (second output) and RF output (first output), contributing to a reduction in the number of electrodes 50 that make up the parallel electrode group 40. Furthermore, the upper electrode 61, intermediate electrode 75A, intermediate electrode 75B, and the lower electrode 69, which are electrodes 50 that make up the parallel electrode group 40, are also electrodes that are used in common for the IP output (third output), further contributing to a reduction in the number of electrodes 50 that make up the parallel electrode group 40.

[0145] The IP output portion shown in Figure 19 is generated, for example, by the IP electrode control unit 153 applying a third output voltage for IP output between the electrodes 50 constituting the parallel electrode group 40 of the head unit 30 and the main body electrode 20(50). Normally, current is supplied to all electrodes 50 constituting the parallel electrode group 40 of the head unit 30, but it may also be supplied to only some of the electrodes 50 constituting the parallel electrode group 40.

[0146] Furthermore, the RF output portion shown in Figure 19 is generated, for example, by applying a first output voltage for RF output to at least one of the two points between the upper electrode 61 and the intermediate electrode 75A, and between the intermediate electrode 75B and the lower electrode 69, by the RF electrode control unit 152. The electrode pair consisting of the upper electrode 61 and the intermediate electrode 75A is the proximity electrode pair 83A, and the electrode pair consisting of the intermediate electrode 75B and the lower electrode 69 is the proximity electrode pair 83C.

[0147] The illumination of a single row of LED lights can be switched and adjusted by selecting the wavelift mode using the power / mode switch 18, level switch 17, etc.

[0148] (modified version) Figure 20 shows a first modified example of the intermediate electrode group. Figure 21 shows a second modified example of the intermediate electrode group. Figure 22 shows a third modified example of the intermediate electrode group. Figures 20 to 22 show modified examples of the intermediate electrode group 70 shown in Figure 2, etc.

[0149] In the beauty device 1A of the first embodiment shown in Figure 2, the intermediate electrodes 75A and 75B constituting the intermediate electrode group 70 are curved in shape. However, in a modified example of the beauty device 1A of the first embodiment, which is not shown in its entirety, the shape of the intermediate electrode group 70 may be as shown in Figures 20 to 22.

[0150] The shape of the intermediate electrode 75 constituting the intermediate electrode group 70 shown in Figure 20 is linear. The shape of the intermediate electrode 75 constituting the intermediate electrode group 70 shown in Figure 21 is V-shaped. The shape of the intermediate electrode 75 constituting the intermediate electrode group 70 shown in Figure 22 is S-shaped.

[0151] In a modified example of beauty device 1A, the intermediate electrode groups 70, which have the shapes shown in Figures 20 to 22, are arranged to replace the intermediate electrode groups 70 of the head portion 30A in Figure 5, with their respective vertical directions aligned with the electrode parallel direction P in Figure 5.

[0152] Here, the electrode extension direction E of the intermediate electrode group 70 with the shape shown in Figure 20 is the left-right direction in Figure 20. The electrode extension direction E of the intermediate electrode group 70 with the shape shown in Figure 21 is the two longitudinal directions of the two straight lines that constitute the V shape. The electrode extension direction E of the intermediate electrode group 70 with the shape shown in Figure 22 is the tangential direction of the adjacent end 52 of the S-shaped intermediate electrode 75. In Figure 22, the tangential direction of the adjacent end 52 of the intermediate electrode 75 is one of the following: the up-down direction, an oblique direction with a different inclination relative to the up-down direction, or the left-right direction.

[0153] Therefore, in the modified beauty device 1A equipped with the intermediate electrode group 70 having the shape shown in Figures 20 to 22, it can be said that the electrode extension direction E is arranged to intersect with the electrode parallel direction P of the parallel electrode group 40 including the intermediate electrode group 70.

[0154] Note that the intermediate electrode group 70 with the shape shown in Figures 20 to 22 may have a different number of intermediate electrodes 75 than those shown in Figures 20 to 22.

[0155] The beauty device 1 (1A1) may be equipped with an inter-electrode distance voltage application unit that applies voltages of different frequencies according to the inter-electrode distance of the parallel electrode group 40. The beauty device 1A1 is preferable because it can apply voltages of different frequencies with different effects according to the inter-electrode distance.

[0156] In beauty device 1(1A2), the electrode-to-electrode distance voltage application unit may apply a higher frequency voltage between the closer electrodes among the distances between each electrode of the parallel electrode group 40. In beauty device 1A2, it is preferable that the beauty effect from the first output is more likely to be enhanced when the higher frequency is, for example, the first frequency.

[0157] In the beauty device 1 (1A3), voltage may be applied only between the pair of electrodes at the ends of the head portion 30 (the pair of electrodes 89) in the parallel electrode group 40. According to the beauty device 1A3, it is preferable that the voltage of the second output is applied only to the pair of electrodes 89 at both ends, as this tends to enhance the beauty effect of the second output.

[0158] In the beauty device 1 (1A4), the frequency of the voltage applied only between the pair of electrodes at the ends of the head portion 30 (the pair of electrodes 89) in the parallel electrode group 40 may be 1 Hz to 10 kHz. According to the beauty device 1A4, when a second output voltage with a frequency of 1 Hz to 10 kHz is applied only to the pair of electrodes 89, it is preferable because the second output makes it easier to tighten the skin through a muscle exercise effect.

[0159] In the beauty device 1 (1A5), the frequency of the voltage applied between the closer electrodes in the parallel electrode group 40 on the head portion 30 may be 1 MHz to 5 MHz. The beauty device 1A5 is preferable because the first output has a warming effect on the skin, which helps to reduce wrinkles and sagging, and provides a comfortable warming sensation.

[0160] The beauty device 1 (1A6) may have one or more electrodes on the main body 10, some or all of the electrodes on the head 30 be of the same polarity, and the electrodes on the main body 10 be of opposite polarity. The beauty device 1A6 is preferable because the efficiency of ion introduction of beauty ingredients tends to increase when a third output voltage is applied between the electrodes on the main body 10 and the electrodes on the head 30.

[0161] The beauty device 1 (1A7) may also be configured to apply a voltage between the head portion 30 and the main body portion 10. In the case of beauty device 1A7, it is preferable because the efficiency of ion introduction of beauty ingredients tends to increase when a third output voltage is applied between the electrodes of the main body portion 10 and the electrodes of the head portion 30.

[0162] In the beauty device 1 (1A8), the electrode-to-electrode distance voltage application unit may alternately apply voltages of different frequencies to each electrode when applying voltages of different frequencies according to the distance between each electrode of the parallel electrode group 40. The beauty device 1A8 is preferable because it allows for a reduction in the number of electrodes 50 and thus a smaller head portion 30.

[0163] In the beauty device 1 (1A9), when the electrode-to-electrode distance voltage application unit applies voltages of different frequencies according to the distance between each electrode of the parallel electrode group 40, the application time may be longer for electrodes that are closer together. According to the beauty device 1A9, it is preferable that the application time of the first output to electrodes that are closer together is longer, as this prolongs the skin warming effect of the first output and tends to reduce wrinkles and sagging of the skin.

[0164] Beauty device 1 (1A10) may have different frequencies than beauty device 1A9, such as EMS, RF, or IP. Beauty device 1A10 is preferable because it enables EMS treatment, RF treatment, or IP treatment.

[0165] The beauty device 1 (1A11) may have a mode for changing the application method when the inter-electrode distance voltage application unit applies voltages of different frequencies according to the inter-electrode distance of each electrode in the parallel electrode group 40. The beauty device 1A11 is preferable because it facilitates the application of voltages of different frequencies.

[0166] The beauty device 1 (1A12) may have one or more LED light irradiating units (LED lights) 35 in its head section 30 that emit LED light. The beauty device 1A12 is preferable because, for example, when red LED light is irradiated onto the skin, it can promote the repair of skin cells, blood circulation, and soothe skin inflammation and redness.

[0167] (action) The operation of beauty device 1A will now be explained. When using beauty device 1A, first the user operates the power / mode switch 18 and the level switch 17 on the main unit 10 to select a usage mode and level, such as wave lift mode or RF treatment mode. Next, the user grasps the main unit 10 and places the head unit 30A in contact with the user's skin.

[0168] The user moves the head unit 30A, which is in contact with the skin, in the treatment direction according to the usage mode. The treatment direction is not particularly limited, but for example, in RF treatment mode, the head unit 30A is moved in the following order: first treatment direction, second treatment direction, and third treatment direction. For example, the first treatment direction is horizontal from near the center of the face toward the temples, the second treatment direction is upward from the mandible toward the eye area, and the third treatment direction is upward on the forehead, starting from the brow ridge. In this case, the treatment directions are horizontal and upward.

[0169] The head portion 30A is provided with a parallel electrode group 40, which is an assembly of three or more electrodes 50 arranged in parallel, and each electrode constituting the parallel electrode group 40 has the shape and size shown in Figure 2. Therefore, with the beauty device 1A equipped with the head portion 30A, current can be supplied substantially uniformly in the direction of treatment, even when the treatment direction is the lateral or upward direction as described above.

[0170] Furthermore, as shown in Figure 5, if the electrical connection of the head unit 30A is configured to allow the application of output voltages of different frequencies to the same electrode, it becomes possible to reduce the size of the head unit 30A while still being able to conduct currents with different characteristics. In this case, precise treatments on areas such as the eyes become possible using the small head unit 30A, resulting in a high level of cosmetic effect across the entire treatment area, including the eyes.

[0171] (effect) The beauty device 1A comprises a main body 10 that is held by the user, and a head 30 provided on a part of the main body 10 that can conduct currents with different characteristics to the user's skin. The head 30 has a parallel electrode group 40 which is an assembly of three or more electrodes 50 arranged in parallel. In the beauty device 1A, a voltage of a first output (RF output) having a first frequency is applied between a pair of nearby electrodes 83, and a voltage of a second output (EMS output) having a second frequency lower than the first frequency is applied between a pair of distant electrodes 87.

[0172] Therefore, with beauty device 1A, it is possible to conduct currents with different characteristics while keeping the head small, thus providing a beauty device that can produce high beauty effects through precise treatment.

[0173] In beauty device 1A, at least one electrode 50 among the electrodes 50 constituting the parallel electrode group 40 can be a common electrode 50 to which a voltage with an output having a different frequency is applied. With such a beauty device 1A, it is possible to provide a beauty device that can reduce the number of electrodes 50 and thus reduce the size of the head portion 30.

[0174] In beauty device 1A, an intermediate output voltage having an intermediate frequency lower than the first frequency and higher than the second frequency can be applied between the medium-range electrode pair 85. With such beauty device 1A, it is possible to provide a beauty device that can be expected to have beauty effects specific to the intermediate output in addition to the first output (RF output) and the second output (EMS output).

[0175] In beauty device 1A, a voltage of the second output (EMS output) can be applied between the electrode pair 89 at both ends. With such beauty device 1A, it is possible to provide a beauty device that is more likely to contract and relax facial muscles with electrical stimulation, thereby achieving firmer skin.

[0176] In beauty device 1A, the second frequency of the second output (EMS output) can be set to 1Hz to 10kHz. With such beauty device 1A, it is possible to provide a beauty device that is more likely to contract and relax facial muscles with electrical stimulation, thereby achieving firmer skin.

[0177] In beauty device 1A, the first frequency of the first output (RF output) can be set to 1MHz to 5MHz. With such beauty device 1A, the first output provides a warming effect on the skin, which helps to reduce wrinkles and sagging, and provides a comfortable warming sensation.

[0178] In the beauty device 1A, a third output voltage can be applied between at least some of the electrodes constituting the parallel electrode group 40 of the head unit 30 and the main body electrode 20 of the main body unit 10. The third output voltage can be applied such that all of the electrodes constituting the parallel electrode group 40 to which the third output voltage is applied are of the same polarity, and the electrodes constituting the parallel electrode group 40 to which the third output voltage is applied and the main body electrode 20 are of opposite polarity. With such a beauty device 1A, it is possible to provide a beauty device with high efficiency in iontophoresis of beauty ingredients.

[0179] In beauty device 1A, the third output can have a third frequency lower than the first frequency. With such beauty device 1A, an electroosmotic flow is generated from the skin surface to the interior, allowing moisturizing ingredients to penetrate deeper into the skin than when applied by hand, thereby providing a beauty device that enhances the beauty effects of beauty ingredients.

[0180] In beauty device 1A, the third frequency can be set to 1kHz to 10kHz. With such beauty device 1A, an electroosmotic flow is generated from the skin surface to the interior, allowing moisturizing ingredients to penetrate deeper into the skin than when applied by hand, thereby providing a beauty device that enhances the beauty effects of beauty ingredients.

[0181] In beauty device 1A, the first output and the second output can be output alternately at different time intervals. With such beauty device 1A, since voltage can be applied to the same electrode, it is possible to provide a beauty device that can reduce the number of electrodes 50 and thus reduce the size of the head portion 30.

[0182] In beauty device 1A, the first output can be applied for a longer period than the second output. With such beauty device 1A, the skin warming effect from the first output is prolonged, making it possible to provide a beauty device that is more likely to reduce wrinkles and sagging of the skin.

[0183] 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 claims or their equivalents. [Industrial applicability]
