2. Description of the Related Art Beauty devices that apply current at a predetermined frequency have been known. Beauty devices that provide electrical muscle stimulation called EMS (Electrical Muscle Stimulation) and RF beauty devices that use higher frequency bands to provide a heating effect to improve skin firmness and elasticity are available.
In addition, electricity is passed into the user's body from the electrode to perform an action called ion introduction and ion extraction, which makes it easier for the lotion to penetrate along with the moving charges, and wipes off waste products on the skin surface with the cotton attached to the electrode side. There are techniques known to make it easier.

With EMS, electrical stimulation is applied to the skin at a frequency of several Hz to several kHz, causing muscle contraction and movement, which can improve sagging skin.
Furthermore, in RF, for example, a high frequency of about 1 MHz is used to warm the inside of the skin, promote the production of collagen and elastin, and improve wrinkles, firmness, and sagging.

Furthermore, in recent years, a technique called mesoporation method for introducing polymeric substances or polar substances has become known. According to Non-Patent Document 1, an experiment is introduced in which a vitamin C derivative is introduced by a mesoporation method using a pulsed current.

It is also described that a grip electrode is provided. This document discloses a beauty device that includes two crescent-shaped electrodes above and below a central electrode.

Patent Document 2, which is also based on the present application, describes that band-shaped electrodes are provided concentrically and that a grip electrode that contacts the palm of the user's hand is provided. The skin is moisturized by introducing negative ions into the subcutaneous tissue, and in the current stimulation mode, a weak low-frequency current is supplied between the two dual-purpose electrodes that are in contact with the skin surface. It is described that it imparts a beautifying effect to the skin. This document discloses a structure in which crescent-shaped electrodes are arranged in parallel, and a structure in which two electrodes are arranged in a large circular shape and a triangular shape.

Patent Document 3 describes that an electrode portion is formed at the center of a cylindrical tip portion, and three pairs of electrode portions are formed on the outer periphery of the electrode portion. This document illustrates a pair of electrodes that are adjacent to each other, and describes that micropores are formed in the cell membrane of the skin by electroporation between the electrodes.

According to the above-mentioned prior art, various electrode configurations are disclosed for exerting different types of cosmetic effects, such as iontophoresis and electrical stimulation. However, these conventional techniques have three problems.
First, the electrodes for exerting their respective effects are fixed, so that, for example, the area to which electrical stimulation is applied is always the same. It is not possible to apply electricity to various parts of the skin surface.
Second, since the center electrode and the electrodes provided on the outer periphery are used for the purpose of exerting their respective functions, it is not assumed that currents having two or more characteristics are applied at the same time. Therefore, it is not possible to provide various beauty effects.
Thirdly, the electrodes are all flat in shape, and the applied current tends to disperse, making it difficult to provide effective electrical stimulation with a small amount of power.

Embodiments of the present invention will be described below based on examples shown in the drawings. Note that the embodiments are not limited to the following.
1 and 2 are a perspective view, a front view, and a right side view of a beauty device (1) according to the present invention. The beauty device (1) is composed of a main body (10) that is held by a user's hand, and a head (11) that is provided with electrodes. The main body (10) is equipped with a level switch (12) for adjusting the level of sensation, a power switch (13) for turning the power on/off and switching modes, and an indicator (14) for indicating the state of the main body. . Note that these operating mechanisms and display mechanisms can be changed arbitrarily.

The main body (10) is equipped with a rechargeable battery and can be charged or used by being supplied with power from a power supply terminal provided on the bottom, but it does not matter whether it has a charging function or not and the method of power supply.

The head part (11) is equipped with a plurality of electrodes according to the present invention, and when the user brings the head part (11) into contact with the skin surface, beauty effects such as electrical stimulation and ion introduction/derivation can be produced. I can do it. First, the head portion (11) is provided with one central electrode (20) at the center thereof, and eight peripheral electrodes (21a to 21g) at positions spaced apart in the peripheral direction of the central electrode (20). In addition, the exterior of the main body (10) is equipped with a hand electrode (22) that can be energized when the user holds it with his or her hand.

FIG. 3 shows an explanatory diagram of the electrodes of the beauty device according to the present invention. The center electrode (20) is an annularly protruding conductor, and in this embodiment is made of a stainless steel material. The center electrode (20) has a diameter of 10 mm and is energized as a pair with the hand electrode (22). Since the hand electrode (22) is arranged along the periphery of the main body (10), it is in a position where it always comes into contact with the user's palm when the main body (10) is gripped.

Note that the hand electrode (22) may be provided in a band shape on the front side, back side, etc. of the main body (10). In any case, it is preferable to have a configuration in which the grip contacts naturally in a sufficiently wide range so as to reduce contact resistance when the grip is held.

In the present invention, the central electrode (20) is used as a cathode, and the hand electrode (22) is used as an anode, and negative charges reach the deep part of the skin from the central electrode (20). Therefore, lotion that is applied to the skin or soaked in cotton is charged with negative ions, which makes it easier to absorb and absorb into the skin. This is so-called iontophoresis, and in this embodiment, the central electrode (20) can provide moisturizing care to the skin surface. Note that the configuration may be such that the anode and the cathode are reversed and ions are extracted.

The outer peripheral electrodes (21a to 21g) are provided at the vertices of a virtual regular octagon so as to surround the center electrode (20). The outer peripheral electrodes (21a to 21g) have a substantially dot-like shape with a diameter of 5 mm at the base, and are made of stainless steel in this embodiment.
The center of the central electrode (20) is arranged to be located inside a regular octagon formed by connecting the outer peripheral electrodes (21a to 21g) in order in the circumferential direction. With this arrangement, as will be described later, it is possible to make the head portion (11) smaller while increasing the distance between the outer peripheral electrodes and to perform various cosmetic effects.

BACKGROUND ART A configuration in which concentric annular electrodes are used in beauty devices such as EMS and RF has been well known. However, in the case of such annular electrodes, there is a problem that lotion or sweat adheres to the skin surface in contact with the electrodes, causing the current to be biased toward the parts that are more likely to conduct electricity, and the effect may not necessarily be uniform. Ta.

Further, the electrodes in conventional beauty devices are generally planar and have a larger area than the electrodes of the present invention. Therefore, the current tends to disperse on the skin surface, making it impossible to provide stimulation efficiently.
Furthermore, when wide electrodes are used in a limited electrode area, the distance between the electrodes becomes short, and there is a problem that the effect cannot be fully exerted unless the facial muscles are properly sandwiched between the electrodes.

In the present invention, by arranging the electrodes in a substantially dotted manner, if a potential difference is generated between predetermined electrodes among the outer peripheral electrodes, it is possible to accurately energize the target region. Since the dot-shaped electrodes are in local contact with the skin, they can provide stimulation similar to cosmetic acupuncture, and also contribute to the efficient delivery of moisturizing ingredients such as hyaluronic acid and ascorbic acid to the stratum corneum. .

Therefore, in the present invention, the size of the substantially dot-shaped outer peripheral electrode is an important factor. The diameter of the outer electrode is preferably in the range of 3 mm to 5 mm. When configured with such a small diameter, even if the output power is small, it becomes easier to experience and the beauty effect can be enhanced. Since strong stimulation can be obtained even if the output is suppressed, power saving can also be achieved.

According to experiments conducted by the inventors, when the diameter is less than 2 mm, the contact area between the electrode and the skin surface becomes too small, making it difficult to feel electrical stimulation. On the other hand, it is known that if the diameter exceeds 6 mm, the electrodes will become large as in the conventional configuration, making it difficult to maintain sufficient distance between the electrodes, and the effect of local stimulation will be reduced. Therefore, at least the diameter of the outer peripheral electrode is in the range of 2 mm to 6 mm, particularly in the range of 3 mm to 5 mm.
Note that the electrodes may have different sizes; for example, electrodes with a diameter of 3 mm and electrodes with a diameter of 5 mm may be mixed.

In the outer peripheral electrodes, the center-to-center distance L between the farthest electrodes (for example, 21a and 21e) is 20 mm. In the present invention, by arranging substantially dot-shaped electrodes on the outer periphery, a long distance between the electrodes can be achieved with a minimum area of the head portion (11). In this respect as well, the configuration according to the present invention in which small-diameter outer electrodes (21a to 21g) are provided at the apexes of the polygon is advantageous.

The center-to-center distance L is preferably at least 10 mm in order to act accurately on various facial muscles as described above. The present invention achieves particularly great cosmetic effects by making the head portion (11) compact in size and accommodating fine muscles, while applying strong electrical stimulation from substantially dot-shaped peripheral electrodes.
In particular, as in this embodiment, L=about 20 mm is optimal for an outer peripheral electrode with a diameter of 5 mm.

In this embodiment, an alternating current is applied between a predetermined combination of electrodes among the outer peripheral electrodes (21a to 21g) to provide electrical stimulation. The AC frequency for EMS is preferably in the range of several Hz to several kHz.

The specific shapes of the outer peripheral electrodes (21a to 21g) are shown in FIGS. 4(a) and 4(b). In the present invention, it is preferable that the outer circumferential electrode has a circular head shape with an apex on the skin surface side. That is, by forming the circular head shape with a small diameter, the outer peripheral electrodes (21a and 21b in the figure) can easily penetrate into the skin (2), and the current (E) between the electrodes can flow directly into the skin. In this respect, conventional planar electrodes do not dig into the skin, so only the current that flows in an arc between the surfaces can reach the inside. According to the present invention, voltage can be efficiently applied inside the skin.

FIG. 4(b) shows another embodiment in which the outer peripheral electrodes (21a', 21b', . . . ) are configured in a substantially conical shape, which provides more local stimulation to the skin (2) than the configuration in (a). It is easily configured. If the tip is sharpened, it can provide electrical stimulation as well as stimulation to the skin, similar to cosmetic acupuncture, by the electrodes pressing strongly against the skin.
The substantially conical shape referred to in the present invention can also include a truncated cone having a minute upper surface.

In the above embodiment, the number of outer peripheral electrodes is eight. In this regard, it is preferable to conduct electricity in at least orthogonal directions, so four electrodes may be used.However, in view of the fact that facial muscles are finely located in various directions, in the present invention, it is preferable to conduct electricity in at least perpendicular directions. The electrodes are arranged in an octagonal shape so that electrical stimulation can be applied. On the other hand, since orthogonal components cannot be formed in a hexagonal shape, it is particularly preferable to have eight or more elements.

If the number is 8 or more, for example, even if there are 9 electrodes, it is possible to select electrodes that are close to orthogonal and have an angle of 80 degrees, which is suitable.
On the other hand, if the number of electrodes exceeds 12, it becomes difficult to arrange them compactly in the head portion (11), and it becomes difficult to provide electrodes with the above-mentioned optimum diameter. Furthermore, although the control becomes more complex, there is no difference in effectiveness.
Therefore, according to the inventor's knowledge, the optimum number of electrodes is 8 to 12.

The shape of the beauty device (1) of the present invention is as described above, and next, a method for controlling the beauty device according to the present invention will be explained.
FIG. 5 is a configuration diagram of a beauty device according to the present invention. For example, a control section (30) realized by a computer or an electric circuit, a power supply section (31), a level switch (12), and a power switch (13) that can output currents with different characteristics according to the control of the control section (30). The main body (10) is equipped with an operation section (32) and the like to perform the operation.

As described above, a first current having a first characteristic suitable for iontophoresis is output between the center electrode (20) and the hand electrode (22). The first current is, for example, a direct current of about 1V to 20V, and when the user selects the iontophoresis mode with the operation unit (32), the control unit (30) controls the power supply unit (31) to output the first current. be done.

Note that the first current may be a direct current reversed, or may be a pulse current. In the case of a pulse current, the power supply section (31) may include an oscillation circuit, or the pulse wave may be output by software using a computer clock.
A pulse current suitable for iontophoresis preferably has an output voltage of about 5 V and a frequency of 1.5 kHz, for example.

On the other hand, regarding the outer circumferential electrodes, the control unit (30) controls a first electrode group (23) selected from one or more outer circumferential electrodes and a second electrode group (24) selected from one or more outer circumferential electrodes. A second current having a second characteristic is applied to the pair from the power supply unit (31). At this time, by changing the combination of the outer peripheral electrodes constituting the first electrode group (23) and the second electrode group (24), control is performed so that the part to which the current is applied changes over time.

FIG. 6 is an example of a control method according to the present invention. First, in FIG. 6(a), the outer circumferential electrode (21a) is a first electrode group (23), and the outer circumferential electrode (21e) located symmetrically with the center electrode (20) in between is a second electrode group (24). . Here, each electrode group consists of one outer peripheral electrode.

An alternating current for electrical stimulation is applied to the skin surface from the power supply unit (31). After a predetermined time has elapsed, the control unit (30) switches the outer electrode (20b) to the first electrode group (23) and the outer electrode (20f) to the second electrode group (24) to output an alternating current. After another second, the outer electrode (20c) is transferred to the first electrode group (23), the outer electrode (20g) is transferred to the second electrode group (24), and after another second, the outer electrode (20d) is transferred to the first electrode group (23). , the outer circumferential electrode (20h), the second electrode group (24), and so on are repeated in this order.

According to the method for controlling peripheral electrodes according to the present invention, it is possible to arrange a large number of peripheral electrodes within the area of the conventional head part (11) and apply stimulation from multiple directions to the skin surface in contact with the head part (11). Contribute to improvement and diversification of effectiveness.
For example, when applying the cosmetic device (1) to facial expression muscles, muscles in various directions can be stimulated from many directions.

In FIG. 6(b), two outer circumferential electrodes (21a) (21b) are placed in the first electrode group (23), and outer circumferential electrodes (21e) (21f) located at symmetrical positions with the center electrode (20) in between are placed in the second electrode group (23). This is referred to as an electrode group (24).

An alternating current for electrical stimulation is applied to the skin surface from the power supply unit (31). After a predetermined time has elapsed, the outer electrodes (21c) (21d) are switched to the first electrode group (23) and the outer circumferential electrodes (21g) (21h) are switched to the second electrode group (24) by the action of the control unit (30). Outputs alternating current and repeats this in sequence.
With this control method as well, the direction of electrical stimulation can be changed in two orthogonal directions, and by using two electrodes, it is possible to increase the output more than in the case of one electrode.

FIG. 7 shows yet another control method. In this method, in state A, the outer peripheral electrodes (21a, 21b, and 21c) are the first electrode group (23), and the outer peripheral electrodes (21e, 21f, and 21g) are the second electrode group (24). In the next state B, the outer electrodes (21b), (21c), and (21d) that have been moved one place in the circumferential direction are placed in the first electrode group (23), and the outer electrodes (21f, 21g, and 21h) are placed in the second electrode group (21h). 24). They are shifted one by one in order, and in state E, the polarity is reversed from that of A, and after state H, the state returns to state A.

With the configuration shown in FIG. 7, the direction of electrical stimulation can be sequentially switched while ensuring a sufficient electrode area, so it is possible to realize a stimulation mode that has not been provided by conventional beauty devices.

As mentioned above, the number of electrodes constituting each electrode group only needs to be one or more, so in FIG. 7, the outer electrode (21a) is the first electrode group (23), and the outer electrode (21e) is the second electrode. It may also consist of groups (24) and one electrode each. Similarly, the outer circumferential electrodes (21a) and (21b) are each composed of two electrodes, such as the first electrode group (23), and the outer circumferential electrodes (21e) and (21f) are composed of two electrodes, such as the second electrode group (24), and the outer circumferential electrodes (21a) (21b) (21c) (21d) are the first electrode group (23), and the outer peripheral electrodes (21e) (21f) (21g) (21h) are the second electrode group (24). It may be composed of

The positions of the first electrode group (23) and the second electrode group (24) may be changed, and the second current may be changed at each position.

Up to this point, the configuration has been such that currents having one characteristic are output for each of the first current and the second current, but in the present invention, currents having a plurality of characteristics can also be output to the outer peripheral electrode. This will be explained using FIG. 6(a).

That is, a high frequency (1 kHz) current having the second characteristic is output between the outer circumferential electrode (21a) and the outer circumferential electrode (21e) which face each other with the center electrode (20) in between, and the outer circumferential electrode (21b) and the outer circumferential electrode (21b) A low frequency (10 to 0 Hz) current having the third characteristic can be output between the outer peripheral electrode (21f) and the outer electrode (21f).

Conventionally, a single waveform was applied at the same time regardless of the number of electrodes, but according to the present invention, a mixed waveform of current can be applied to the skin surface, and the beauty effect according to the characteristics of each current can be applied. features can be operated simultaneously.

In the present invention, it is more preferable to combine ion introduction using the central electrode (20) and the hand electrode (22) with high frequency and low frequency output using the outer peripheral electrode.
That is, the effect of introducing lotion, vitamin A, vitamin C derivatives, etc. can be enhanced by stimulating muscle fibers and promoting blood circulation using pulsed current from the peripheral electrode.

In addition, since the two functions of iontophoresis and EMS lift-up, which were previously performed separately, can be performed at the same time, you can obtain both effects in half the time compared to conventional methods, reducing the time required for beauty treatments. Contribute.

Furthermore, it is thought that the effect of introducing lotion, vitamin A, vitamin C derivatives, etc. can be further enhanced by outputting a current suitable for mesoporation using the peripheral electrode, not only for electrical muscle stimulation.

Finally, FIG. 8 shows an example in which the number of outer peripheral electrodes is other than eight.
FIG. 8(a) illustrates the case of three outer peripheral electrodes (25a) (25b) (25c). In the present invention, as long as at least three outer peripheral electrodes are provided, for example, energization between two electrodes (25a) (25b), energization between electrodes (25b) (25c), and energization between electrodes (25c) (25a). It is possible to switch sequentially, and the effect can be sufficiently produced.

FIG. 8(b) illustrates the case of four outer peripheral electrodes (26a), (26b), (26c), and (26d). In this case, for example, the two electrodes (26a) (26b) are the first electrode group (23), the electrodes (26c) (26d) are the second electrode group (24), and then the electrodes (26a) (26b) are the second electrode group (24). By switching the two electrode groups (24), the electrodes (26c) and (26d) to the first electrode group (23), it is possible to change orthogonal directions and make them work.

FIG. 8(c) illustrates the case of five outer peripheral electrodes (27a to 27e). In this case, for example, the two electrodes (27a and 27b) may be used as the first electrode group (23), and the electrode (27d) may be used as the second electrode group (24). In this way, the number of electrodes does not necessarily have to be equal within a pair. Next, the electrodes (27b) (27c) can be sequentially switched to the first electrode group (23), the electrodes (27e) to the second electrode group (24), and so on.

As explained above, the present invention can be implemented as appropriate as long as the number of outer peripheral electrodes is 3 or more, and the present invention can be implemented in the same way even with 6, 7, 9 or more electrodes (not specifically shown). It is clear that this can be done.
