Embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Hereinafter, similar elements will be denoted by the same reference numerals in all drawings, and redundant explanation will be omitted. In addition, in the explanations in this text, the symbols mentioned earlier will be used as necessary.

FIG. 1 is a configuration diagram of a facial beauty device 10 according to an embodiment of the present invention. The facial beauty device 10 includes a charger 12, a pedestal 14, a casing 16, a main battery 18, an electric circuit section 20, an input side electrode section 22, and an output side electrode section 24.

The charger 12 has a function of being connected to a commercial AC power source, for example, a household AC outlet, converting voltage, and supplying power to the main battery 18 . The charger 12 is connected to a household AC outlet on one side and connected to the base 14 on the other side.

The pedestal 14 has a structure for erecting the casing 16, and has a concave shape in its upper portion into which the casing 16 is fitted. A connecting portion is attached to the base 14 for electrically connecting the charger 12 and the connecting portion 16a of the casing 16 when the casing 16 is placed upright.

The casing 16 is a housing that includes a main battery 18 and an electric circuit section 20 therein, and has an output side electrode section 24 installed at the top and an input side electrode section 22 installed at the side surface. .

The main battery 18 is a secondary battery that can be charged by the charger 12, and can be configured using, for example, a lithium ion secondary battery, a nickel-hydrogen storage battery, or a nickel-cadmium storage battery. The main battery 18 has one side connected to a connection part 16a for electrically connecting to the charger 12, and the other side connected to the electric circuit part 20.

The electric circuit section 20 operates with power supplied from the main battery 18 and has a function of supplying current to the output side electrode section 24 and the input side electrode section 22 based on a predetermined pattern. The electric current pattern supplied by the electric circuit section 20 includes a negative pattern shown in FIG. 2 and a positive pattern shown in FIG. 3.

In the positive pattern, current flows from the output side electrode section 24 to the input side electrode section 22 via the skin. In the negative pattern, current flows from the input side electrode section 22 to the output side electrode section 24 via the skin.

Although the electric circuit section 20 will be described as supplying both a negative pattern current and a positive pattern current, an operation button (not shown) may be installed to supply only one pattern of current. It can also be used as a thing.

The output side electrode part 24 is formed to protrude from the upper part of the casing 16, and has a flat surface with which a predetermined area comes into contact when the output side electrode part 24 is applied to the skin. The input side electrode portions 22 are arranged along the longitudinal direction on both side surfaces of the casing 16, and are arranged so as to come into contact with the hand when the casing 16 is held by the hand in order to apply the output side electrode portion 24 to the skin. has been done. As a result, the input-side electrode section 22 and the output-side electrode section 24 become electrically connected through the human body.

The output side electrode part 24 is a metal part made of brass containing zinc and 60% or more of copper. The output side electrode portion 24 is not covered by plating or the like, and is configured with the brass exposed, and the brass comes into contact with the human skin.

The casing 16 is provided with a power button 26, a High button 28, and a Low button 30. The power button 26 has a function of connecting or interrupting the current path between the main battery 18 and the electric circuit section 20.

The High button 28 has a function of setting the voltage value for supplying the current of the negative side pattern and the positive side pattern to a high voltage (45V). The Low button 30 has a function of setting the voltage value for supplying the current of the negative side pattern and the positive side pattern to a low voltage (25V).

FIG. 2 is a diagram showing a current waveform of a negative side pattern. In FIG. 2, the horizontal axis is time (t), and the vertical axis is current value (I). In the negative pattern, intermittent direct current flows in the first stage, alternating current flows in the second stage, and the first stage and second stage are repeated.

Here, the term "intermittent direct current" refers to a current pattern in which a direct current flows for a certain period of time but has a pause period during which no current flows. In this example, as an intermittent DC current, a DC current first flows for 3 seconds, then after a pause period in which no current flows for 1 second, a DC current flows again for 3 seconds.

Immediately after the intermittent direct current is switched to alternating current, a pulsed alternating current flows that goes back and forth between the positive side and the negative side within a predetermined period. In this example, an alternating current period of 1 second is set. It is preferable to set the frequency of the alternating current to, for example, 11 Hz.

FIG. 3 is a diagram showing the current waveform of the positive side pattern. In FIG. 3, the horizontal axis is time (t), and the vertical axis is current value (I). The positive side pattern is set to be symmetrical with the negative side pattern via the horizontal axis.

Next, the operation of the facial beauty device 10 having the above configuration will be explained. While holding the input side electrode part 22 of the casing 16 of the facial beauty device 10 so as to touch it, the flat surface of the output side electrode part 24 is brought into contact with the skin to which the serum has been applied.

At this time, the electric circuit section 20 is activated by operating the power button 26, and the voltage level is selected using the High button 28 and the Low button 30. First, a case where ion introduction is performed using the negative pattern shown in FIG. 2 will be described.

The negative potential ions of the beauty serum are electrically repelled by the negative potential of the output electrode section 24 and penetrate deep into the skin. In addition, dirt on the skin that has a positive potential is electrically attracted and removed by the negative potential of the output electrode section 24. This has the advantage that the beauty serum can penetrate deep into the skin and that dirt on the skin can be appropriately removed.

In this negative-side pattern, a negative current is applied to allow ions of the serum with a negative potential to penetrate, a short rest period is provided in the middle of the DC current, and then the DC current is applied again. Generally, when direct current is supplied, the electrical repulsion force is strongest immediately after it is applied, and the force gradually weakens. In this current pattern, since a short rest period is provided and a rising current is again provided, the introduction of ions can be promoted more than when a constant direct current is continuously applied.

Here, when a negative DC current is applied, ions with a negative potential in the serum penetrate into the skin due to electrical repulsion as described above, and ions with a positive potential inside the skin combine, and the number of ions with a negative potential in the serum and the number of ions with a positive potential inside the skin become balanced. In other words, ions with a negative potential in the serum no longer penetrate.

However, in this negative pattern, alternating current is applied after intermittent direct current. Since this alternating current switches the output side electrode section 24 between negative and positive, the above-mentioned balance is again disrupted, and the subsequent intermittent direct current can cause ions to penetrate again.

Next, a case where ion introduction is performed using the positive pattern shown in FIG. 3 will be described. The positively charged ions of the serum are electrically repelled by the positive potential of the output electrode section 24 and penetrate deep into the skin. This allows the serum to penetrate deep into the skin.

In this positive-side pattern, a positive current is applied to allow ions of the beauty serum with a positive potential to penetrate, a short rest period is provided in the middle of the DC current, and then the DC current is applied again. Similar to the above-mentioned negative side pattern, since a short rest period is provided and a rising current is provided again, the introduction of ions can be promoted more than when a constant direct current is continuously applied.

Here, when a positive DC current is applied, ions with a positive potential in the serum penetrate into the skin due to electrical repulsion as described above, and ions with a negative potential inside the skin The number of ions with a positive potential in the serum and the number of ions with a negative potential inside the skin become balanced.

In other words, ions with a positive potential in the serum no longer penetrate. However, in this positive pattern, like the negative pattern, alternating current is applied after intermittent direct current. This alternating current disturbs the above-mentioned balance again, and the subsequent intermittent direct current allows ions to penetrate again.

As described above, in the facial beauty device 10, ion introduction can be further promoted by using intermittent direct current, and retention of ions can be suppressed by using subsequent alternating current. This allows the serum to penetrate into the skin more efficiently.

In the facial beauty device 10, by using both the negative side pattern and the positive side pattern, both ions with a positive potential and ions with a negative potential in the beauty serum can penetrate deep into the skin. Therefore, compared to iontophoresis using only one side of the pattern, there is an advantage that the serum can be more effectively penetrated into the skin.

Here, in a typical facial beauty device, the portion that comes into contact with the skin is plated with resin or metal. Even if such a general facial beauty device is used on human skin, it has no bactericidal effect. However, according to the facial beauty device 10 according to the embodiment of the present invention, the beauty serum not only penetrates deep into the skin as described above, but also has a sterilizing effect and an antiviral effect against bacteria and viruses attached to the skin. be. This point will be explained below using experimental data.

In the experiment, the number of viable bacteria was measured after Staphylococcus aureus was attached as a test bacterium to the output electrode section 24 (head portion of the facial beauty device 10) of the facial beauty device 10. As the test conditions, first, the output side electrode part 24 is wiped with absolute ethanol to make it sterile, then Staphylococcus aureus is attached thereto, and an adhesive film made of polypropylene film is placed over it. FIG. 4 shows experimental data obtained by measuring the number of viable bacteria after 5 minutes in this state.

Here, the head portion of Asterion (facial beauty device 10), which is the trade name of the facial beauty device 10 (the output side electrode portion 24, which is the part that comes into contact with the human face), and the head portion made of unprocessed glass and chrome plating. Figure 4 shows the change in the number of viable bacteria after Staphylococcus aureus was attached to the head part made of brass plating and clear cord.

FIG. 4 shows the type of head portion, whether or not the head portion was energized, the number of viable bacteria, and the antibacterial activity value. The number of viable bacteria is on the order of 10 4 (E 4 ) for the head part made of unprocessed glass and chrome plating, and the head part made of brass plating and clear cord, while the number of viable bacteria in the head part of Asterion (output) is on the order of 10 ⁴ (E ⁴ ). The side electrode portion 24) is 10 ² (E ² ) to 10 ¹ (E ¹ ). Furthermore, the antibacterial activity value was detected only for the head part of Asterion, and the values for both the head part made of chrome plating and the head part made of brass plating and clear cord were 0.

As described above, using the facial beauty device 10 according to the embodiment of the present invention, the remarkable effect of having an antibacterial effect can be achieved simply by bringing the output side electrode section 24 into contact with the skin. Furthermore, as shown in FIG. 4, the number of viable bacteria decreases when electricity is applied to the head portion of Asterion compared to when electricity is not applied. This is due to the electrical action of the current supplied from the electric circuit section 20. This is because it amplifies the action of metal ions against bacteria and, as a result, contributes to improving antibacterial activity. As described above, the facial beauty device 10 has a remarkable effect of making the skin beautiful while having a sterilizing effect and an antiviral effect against bacteria and viruses attached to the skin.

Although the facial beauty device 10 has been described as a beauty device equipped with the electric circuit section 20, as described above, it has an antibacterial effect even without electric action, so for example, it can be made of brass without being equipped with an electric circuit. If it is an appliance for beauty care using the metal part where the brass is not covered by plating or the like, the facial beauty device 10 will have the same effect. It can also be widely applied to other facial beauty devices.
