Description

Beauty instrument and control method thereof

Technical Field

The present invention relates to a beauty instrument capable of applying an electric current to a skin surface of a user, and a control method thereof.

Background

Conventionally, a beauty instrument for applying a current of a predetermined frequency is known. Known are cosmetic instruments called EMS (Electrical Mu scle Stimulation) which apply electrical stimulation to muscles, and also RF cosmetic instruments which use high frequencies to provide a warming effect, enhance skin elasticity, and compactness.

In addition, a technique is known in which a user is energized from the electrode to perform an action called ion introduction or ion extraction, so that the charge of the lotion accompanying the movement is more easily permeated, and the aged substances on the skin surface are more easily rubbed off by the cosmetic cotton attached to the electrode side.

In EMS, sagging is improved by giving electrical stimulation to the skin at a frequency of several Hz to several kHz, which can cause muscle contraction and thus muscle movement.

In addition, in RF, the skin interior is warmed up using a high frequency of, for example, about 1Mhz, and the production of collagen and elastin is promoted for the purpose of improving wrinkles, tightening, sagging.

In recent years, a technique called needleless cosmetic (Mesoporation) has been known in which a polymer substance or a polar substance is introduced through the skin. Non-patent document 1 describes an experiment for introducing a vitamin C derivative by a needleless cosmetic (Mesoporation) method using a pulse current.

As described above, many cosmetic methods using a cosmetic instrument equipped with an electrode are known, and various proposals have been made as to the structure of the electrode.

According to patent document 1 of the present inventors, there are described a cosmetic treatment electrode functioning as an ion-introducing electrode provided in the center, a cosmetic treatment electrode serving as an ion-introducing and electrical stimulation electrode provided on the periphery thereof, and a grip electrode provided. The present document discloses a cosmetic device having two crescent shaped electrodes at the upper and lower portions of a central electrode.

Also, according to patent document 2 of the present application, it is described that a band electrode is provided concentrically, and a grip electrode is provided in contact with the palm of the user. Also, it is described that skin is moisturized by introducing negative ions into subcutaneous tissue, and a low-frequency weak current is provided between two dual-purpose electrodes and a dual-purpose electrode, respectively, which are in contact with the skin surface, in an electro-stimulation mode, to provide a skin-beautifying effect. In this document, a structure of a crescent electrode arrangement among electrodes, and a structure of two electrodes of a large circle and a triangle are disclosed.

Patent document 3 describes that an electrode portion is formed in the center of a cylindrical tip portion, and three pairs of electrode portions are formed on the outer periphery thereof. In this document, electrodes adjacent to each other are illustrated as a pair of electrodes, and it is described that micropores are formed in the skin cell membrane by electroporation between the electrodes. Further, since the electrode portion of the center portion into which ions are introduced and the 3 pairs of electrode portions of the periphery are energized, the 3 pairs of electrode portions are dual-purpose.

According to the above prior art, structures of various electrodes for exerting different types of cosmetic effects, such as iontophoresis and electrostimulation, are disclosed. However, these prior art techniques have three technical problems.

First, since the electrodes for exerting various functions are fixed, the electrodes are always given to the same place as the electric stimulation. No power can be applied to the various parts of the skin surface.

Second, the electrodes in the center and the electrodes in the outer periphery are both used when they function, and therefore, it is not assumed that the case of simultaneously applying 2 or more characteristic currents is not considered. Therefore, it is impossible to provide various cosmetic effects.

Detailed Description

Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings. The embodiments are not limited to the following.

Fig. 1 and 2 are perspective, front and right side views of the beauty instrument (1) of the present invention. The cosmetic instrument (1) comprises a body part (10) for a user to hold and a head part (11) provided with electrodes. The main body (10) includes a level switch (12) for adjusting the degree of experience, a power switch (13) for switching a power on or off mode, an indicator lamp (14) for displaying the state of the main body, and the like. In addition, these operating mechanisms and display mechanisms may be arbitrarily changed.

The main body (10) is provided with a rechargeable battery, and can be charged by supplying power through a power supply terminal provided on the bottom surface, and can be used by supplying power, and whether the charging function and the power supply method are not limited.

The head (11) is provided with a plurality of electrodes according to the present invention, and the user brings the head (11) into contact with the skin surface to exert a cosmetic effect such as electrical stimulation, ion introduction/extraction, or the like. First, 1 central electrode (20) is provided in the center of the head (11), and 8 peripheral electrodes (21 a-21 g) are provided at positions separated from each other in the peripheral direction of the central electrode (20). In cooperation with this, a handle electrode (22) is provided on the housing of the main body (10) and can be energized when the user holds the same by hand.

Fig. 3 shows an explanatory view of an electrode of the cosmetic instrument of the present invention. The central electrode (20) is a conductor protruding in an annular shape, and is made of a stainless steel material in this embodiment. The central electrode (20) has a diameter of 10mm, is paired with the handle electrode (22), and is energized. Since the handle electrode (22) is provided along the periphery of the body (10), the handle electrode (22) is positioned at a position where it is always in contact with the palm of the user when the body (10) is held.

The handle electrode (22) may be provided in a band shape on the front surface side, the back surface side, or the like of the main body (10). In short, it is preferable that the contact member is provided at a position that can be naturally contacted when held, and is contacted in a sufficiently wide range in order to reduce contact resistance.

In the present invention, the central electrode (20) is a cathode, the handle electrode (22) is an anode, and negative charges reach from the central electrode (20) to the deep part of the skin surface. Therefore, the lotion contained in the cosmetic cotton or the skin surface is adsorbed to the skin with negative ions, making it more permeable. This is so-called iontophoresis, and in this embodiment, the skin surface can be moisturized by the central electrode (20). Alternatively, the anode and the cathode may be reversed to conduct ions.

The peripheral electrodes (21 a-21 g) are arranged at the vertex positions of an imaginary regular octagon so as to surround the central electrode (20). The peripheral electrodes (21 a-21 g) are formed of a stainless steel material in this embodiment in a substantially dot-like shape having a diameter of 5mm at the base.

The center of the center electrode (20) is arranged on the inner side of a regular octagon formed by connecting peripheral electrodes (21 a-21 g) in turn along the circumferential direction. According to this arrangement, as will be described later, the head (11) can be miniaturized and the distance between the peripheral electrodes can be lengthened, thereby exhibiting various cosmetic effects.

There is known a cosmetic instrument such as EMS and RF, which uses a concentric ring electrode structure. However, in the case of such a ring electrode, there is a problem that the skin surface in contact adheres to the cosmetic water and sweat, and the current tends to be biased to a portion where current is easily supplied, and sometimes the function cannot be uniformly performed.

In addition, the electrodes in conventional cosmetic instruments are generally planar and many electrodes have a larger area than the present invention. Therefore, the current is easily dispersed on the skin surface, and effective stimulation cannot be given.

Further, if a wide electrode is used in a limited electrode portion, the distance between the electrodes becomes short, and if facial muscles are not well sandwiched therebetween, there is a problem that the effect cannot be sufficiently exerted.

In the present invention, by arranging them in a substantially dot shape, if a potential difference is generated between specified electrodes among the peripheral electrodes, the target site can be accurately energized. The substantially point-like electrode is in local contact with the skin, and thus provides the same stimulation as in beauty acupuncture, and contributes to the effective delivery of moisturizing components such as hyaluronic acid and ascorbic acid to the stratum corneum.

Therefore, in the present invention, the size of the substantially dot-shaped peripheral electrode is an important factor. The diameter of the peripheral electrode is preferably in the range of 3mm to 5mm. Thus, the cosmetic effect can be enhanced by the small diameter, which is easy to experience even if the output power is small. Even if the output is suppressed, strong stimulation can be obtained, and therefore power can be saved.

According to the experiments of the inventors, when the diameter is less than 2mm, the portion of the electrode in contact with the skin surface becomes too small, and it is difficult to feel the electrical stimulation. On the other hand, it is known that when the diameter exceeds 6mm, the electrodes become large as in the conventional structure, it is difficult to obtain a sufficient distance between the electrodes, and the effect of local stimulation is also weakened. Thus, at least the diameter of the peripheral electrode is in the range of 2mm to 6mm, particularly preferably in the range of 3mm to 5 mm.

In addition, the size of the electrodes may be different, for example, an electrode having a diameter of 3mm and an electrode having a diameter of 5mm may be mixed and used.

Among the peripheral electrodes, the distance L between the centers between the farthest electrodes (e.g., 21a and 21 e) is 20mm. In the present invention, by providing the electrodes in a substantially point shape on the outer circumference, a long distance between the electrodes can be obtained within the minimum area of the head (11). In this respect, it is also advantageous according to the invention to provide the sum structure of peripheral electrodes (21 a-21 g) with small diameters at the vertices of the polygon.

As described above, the distance L between the centers is preferably at least 10mm or more in order to reliably act on various muscles of the face. The head (11) is compact in size and corresponds to fine muscles, and the present invention exerts a particularly large cosmetic effect by applying strong electrical stimulation from the substantially punctiform peripheral electrodes.

In particular, as in the present embodiment, l=20mm is most preferable for the peripheral electrode having a diameter of 5mm.

In this embodiment, alternating current is applied between electrodes of a specified combination among the peripheral electrodes (21 a-21 g) to provide electrical stimulation. The ac frequency used for EMS is preferably in the range of a few Hz to a few kHz.

The specific shape of the peripheral electrodes (21 a-21 g) is shown in fig. 4 (a) and (b). In the present invention, the peripheral electrode is preferably provided in a rounded shape having an apex on the skin surface side. That is, by forming the peripheral electrodes (21 a, 21b in the drawing) in a rounded shape with a small diameter so as to be easily sunk into the skin (2), the current (E) between the electrodes can directly flow into the inside of the skin. In this regard, since the conventional planar electrode cannot sink into the skin, the state thereof is such that only a current flowing in an arc shape between the surfaces can reach the inside. According to the present invention, a voltage can be effectively applied to the inside of the skin.

Fig. 4 (b) is another embodiment in which the peripheral electrodes (21 a ', 21 b'.) are arranged in a generally conical configuration that is easier to apply local stimulation to the skin (2) than the configuration of (a). By tapering the tip, the electrode can strongly press the skin together with the electrical stimulation, giving the skin a cosmetic acupuncture-like stimulation.

The substantially conical shape of the present invention may include a truncated cone formed with a minute top surface.

In the above embodiment, the number of peripheral electrodes is set to 8. In this regard, since it is preferable to energize at least in the vertical direction, 4 electrodes can be provided, but in view of the fact that the facial muscles are finely located in a plurality of directions, in the present invention, an octagonal electrode configuration is provided so that electrical stimulation can be applied in every 45 degrees of direction. In contrast, since the hexagonal structure cannot have a vertical component, it is preferable to provide 8 or more structures.

If the number is 8 or more, for example, even 9, the number of electrodes formed at an angle of 80 degrees can be selected to be close to vertical.

On the other hand, if the number of electrodes exceeds 12, it is difficult to compactly arrange the electrodes at the head (11), and it is difficult to provide the above-mentioned electrodes of the optimal diameter. Further, although the control becomes complicated, there is no difference in effect.

Therefore, the number of electrodes is most suitably 8 to 12, according to the findings of the inventors.

The shape of the beauty instrument (1) of the present invention is as described above, and a control method of the beauty instrument of the present invention will be described next.

Fig. 5 is a schematic view of the beauty instrument of the present invention. A control unit (30) realized by a computer or a circuit, a power supply unit (31) capable of outputting currents of different characteristics according to the control of the control unit (30), an operation unit (32) taking a class switch (12) or a power switch (13) as an example, and the like are mounted inside the main body unit (10).

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

The first current may be a direct current, or a pulse current, with the forward and reverse directions of the direct current being reversed. In the case of a pulse current, the power supply unit (31) may have an oscillation circuit, or a computer clock may be used to output a pulse wave by software.

A pulse current suitable for ion introduction, for example, an output voltage of about 5V and a frequency of 1.5kHz, is preferable.

On the other hand, regarding the peripheral electrodes, a control unit (30) energizes a second current of a second characteristic from a power supply unit (31) to an electrode group pair of a first electrode group (23) selected from 1 or more peripheral electrodes and a second electrode group (24) selected from 1 or more peripheral electrodes. At this time, the combination of peripheral electrodes constituting the first electrode group (23) and the second electrode group (24) is changed, and the position of the applied current is controlled to change with time.

Fig. 6 is an embodiment of a control method according to the present invention. First, in fig. 6 (a), the peripheral electrode (21 a) is the first electrode group (23), and the peripheral electrode (21 e) disposed at a symmetrical position with the central electrode (20) interposed therebetween is the second electrode group (24). Here, each electrode group contains one peripheral electrode.

An alternating current for electrical stimulation is supplied from a power supply unit (31) to the skin surface. After a prescribed time, the control unit (30) switches the peripheral electrode (20 b) to the first electrode group (23) and switches the peripheral electrode (20 f) to the second electrode group (24) to output an alternating current. After 1 second, the peripheral electrode (20 c) was the first electrode group (23), the peripheral electrode (20 g) was the second electrode group (24), after 1 second, the peripheral electrode (20 d) was the first electrode group (23), and the peripheral electrode (20 h) was the second electrode group (24), and the steps were repeated in this order.

According to the control method of the peripheral electrode, after a plurality of peripheral electrodes are arranged in the area of the traditional head (11), the skin surface which is abutted can be stimulated from all directions, thereby being beneficial to improving and diversifying the beauty effect.

For example, when the beauty instrument (1) is applied to expressive muscles of the face, muscles in various directions can be stimulated from multiple sides.

In fig. 6 (b), 2 peripheral electrodes (21 a) and (21 b) are used as a first electrode group (23), and peripheral electrodes (21 e) and (21 f) provided at symmetrical positions with respect to the central electrode (20) are used as a second electrode group (24).

An alternating current for electrical stimulation is supplied from a power supply unit (31) to the skin surface. After a prescribed time, the peripheral electrodes (21 c, 21 d) are switched to the first electrode group (23) and the peripheral electrodes (21 g, 21 h) are switched to the second electrode group (24) by the control unit (30) to output alternating current, and the sequence is repeated.

Even if the present control method is used, it is possible to increase the output power by using two electrodes, compared to the case of one electrode, in addition to being able to change the direction of the electrical stimulus in two directions perpendicular.

Fig. 7 is another control method. In the method, in state A, the peripheral electrodes (21 a), (21 b), (21 c) are arranged as a first electrode group (23) and the peripheral electrodes (21 e), (21 f), (21 g) are arranged as a second electrode group (24). In the next state B, one electrode is moved in the circumferential direction to set the peripheral electrodes (21B) (21 c) (21 d) as the first electrode group (23), and the peripheral electrodes (21 f) (21 g) (21 h) as the second electrode group (24). Shifting one by one in turn, reversing positive and negative with state A in state E, and returning to state A after state H.

In the structure shown in fig. 7, since the direction of the electrical stimulation can be sequentially switched while securing a sufficient electrode area, stimulation which cannot be provided by the conventional beauty instrument at all can be achieved.

In addition, as described above, the number of electrodes constituting each electrode group may be 1 or more, and therefore, in fig. 7, the peripheral electrode (21 a) may be the first electrode group (23), the peripheral electrode (21 e) may be the second electrode group (24), and each electrode may be one electrode. Similarly, the peripheral electrodes (21 a) (21 b) may be two electrodes each, as the first electrode group (23), the peripheral electrodes (21 e) (21 f) may be the second electrode group (24), or the peripheral electrodes (21 a) (21 b) (21 c) (21 d) may be the first electrode group (23), and the peripheral electrodes (21 e) (21 f) (21 g) (21 h) may be the second electrode group (24), as the four electrodes each.

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

The first current and the second current are configured to output currents having one characteristic, respectively, but the present invention may further output currents having a plurality of characteristics to the peripheral electrode. This will be described with reference to fig. 6 (a).

That is, a high-frequency (1 kHz) current of a second characteristic is output between the peripheral electrode (21 a) and the peripheral electrode (21 e) which faces the central electrode (20), and a low-frequency (10-0 Hz) current of a third characteristic is output between the peripheral electrode (21 b) and the peripheral electrode (21 f).

In the past, a single waveform was applied simultaneously regardless of the number of electrodes, but according to the present invention, a mixed waveform current could be applied to the skin surface and a cosmetic effect could be produced according to the characteristics of each current.

In the present invention, it is more preferable to combine iontophoresis based on the center electrode (20) and the handle electrode (22) with high-frequency and low-frequency output power based on the peripheral electrode.

That is, the effect of introducing the astringent, vitamin a, vitamin C derivative, and the like can be enhanced by stimulating muscle fibers with the pulse current from the peripheral electrode to promote blood circulation.

In addition, since the two functions of the conventional ion introduction and the pulling according to the EMS can be simultaneously performed, only half of the conventional time is required to obtain the two effects, which contributes to shortening the time required for beauty treatment.

Further, it is considered that the effect of introducing the cosmetic water, vitamin a, vitamin C derivative, and the like can be further enhanced by outputting a current suitable for needleless cosmetic (Mesoporation) through the outer peripheral electrode, not limited to the electric muscle stimulation.

Finally, fig. 8 shows an embodiment when the peripheral electrodes are other than 8.

Fig. 8 (a) illustrates the case of three peripheral electrodes (25 a) (25 b) (25 c). In the present invention, as long as there are at least three peripheral electrodes, for example, the energization between the two electrodes (25 a) and (25 b), the energization between the electrodes (25 b) and (25 c), and the energization between the electrodes (25 c) and (25 c) can be sequentially switched to achieve a sufficient effect.

Fig. 8 (b) illustrates the case of four peripheral electrodes (26 a) (26 b) (26 c) (26 d). In this case, it is possible to change the direction in the vertical direction and act by, for example, switching two electrodes (26 a) (26 b) to the first electrode group (23), switching the electrodes (26 c) (26 d) to the second electrode group (24), and then switching the electrodes (26 a) (26 b) to the second electrode group (24), and switching the electrodes (26 c) (26 d) to the first electrode group (23).

Fig. 8 (c) illustrates the case of five peripheral electrodes (27 a-e). In this case, for example, the two electrodes (27 a) (27 b) may be the first electrode group (23), and the electrode (27 d) may be the second electrode group (24). As such, the number of the pair of electrodes is not necessarily equal. Then, the electrodes (27 b, 27 c) may be sequentially switched to the first electrode group (23), and the electrode (27 e) may be switched to the second electrode group (24).

As described above, the number of the peripheral electrodes of the present invention may be 3 or more, and may be implemented as appropriate, and specifically, the number of electrodes not shown may be 6, 7, or 9 or more.
