  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following, the same reference numerals are given to the same elements in all the drawings, and redundant description will be omitted. Further, in the description in the text, the reference numerals described earlier are used as necessary.

  FIG. 1 is a configuration diagram of the iontophoretic beauty device 10. The iontophoretic device 10 includes a charger 12, a pedestal 14, a casing 16, a main battery 18, an electric circuit 20, an input electrode 22, and an output electrode 24.

  The charger 12 is connected to a commercial AC power supply, for example, a household AC outlet, performs voltage conversion, and has a function of supplying power to the main battery 18. The charger 12 has one side connected to a household electrical outlet and the other side connected to a pedestal 14.

  The pedestal 14 has a structure for erecting the casing 16, and has a concave shape at the upper portion for fitting the casing 16. The base 14 is provided with a connecting portion for electrically connecting the charger 12 and the connecting portion 16a of the casing 16 when the casing 16 is erected.

  The casing 16 is a housing including a main battery 18 and an electric circuit unit 20 therein, an output-side electrode unit 24 installed on an upper part, and an input-side electrode unit 22 installed on a side surface part. .

  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 hydride storage battery, or a nickel cadmium storage battery. The main body battery 18 has one side connected to the connection portion 16 a for electrically connecting to the charger 12, and the other side connected to the electric circuit section 20.

  The electric circuit section 20 operates with the electric power supplied from the main battery 18 and has a function of supplying a current to the output side electrode section 24 and the input side electrode section 22 based on a predetermined pattern. The current pattern supplied by the electric circuit section 20 includes a negative pattern shown in FIG. 2 and a positive pattern shown in FIG. In the positive pattern, a current flows from the output electrode section 24 to the input electrode section 22 through the skin. In the negative pattern, a current flows from the input electrode section 22 to the output electrode section 24 via the skin. The electric circuit unit 20 will be described as supplying both the current of the negative pattern and the current of the positive pattern. However, an operation button (not shown) is provided to supply only one of the patterns. It may be a thing.

  The output-side electrode portion 24 is formed so as to protrude from an upper portion of the casing 16 and has a flat surface such that a predetermined area thereof comes into contact with the skin. The input-side electrode portions 22 are arranged on both side portions of the casing 16 along the longitudinal direction. The input-side electrode portions 22 are arranged so as to come into contact with the hand when the casing 16 is gripped by the hand so that the output-side electrode portion 24 is brought into contact with the skin. Have been. As a result, the input side electrode portion 22 and the output side electrode portion 24 are brought into conduction through the human body.

  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 disconnecting a current path between the main battery 18 and the electric circuit unit 20. The High button 28 has a function of setting a voltage value for supplying currents of the negative pattern and the positive pattern to a high voltage (45 V). The Low button 30 has a function of setting a voltage value for supplying currents of the negative pattern and the positive pattern to a low voltage (25 V).

  FIG. 2 is a diagram showing a current waveform of a negative pattern. In FIG. 2, the horizontal axis represents time (t) and the vertical axis represents current value (I). In the negative pattern, an intermittent DC current flows as a first stage, and an AC current flows as a second stage, and the first and second stages are repeated. Here, the intermittent DC current means a current pattern having an idle period in which no current flows in the middle when DC current flows for a certain time. In this example, as the intermittent DC current, the DC current first flows for 3 seconds, and then the DC current flows again for 3 seconds after a pause in which no current flows for 1 second.

  Immediately after the intermittent DC current, the current is switched to the AC current, and a pulse AC current flowing between the positive side and the negative side flows within a predetermined period. In this example, an AC current period of one second is set. The frequency of the alternating current is preferably set to, for example, 11 Hz.

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

  Next, the operation of the iontophoretic cosmetic device 10 having the above configuration will be described. While holding the input-side electrode portion 22 of the casing 16 of the iontophoretic beauty device 10 by hand, the flat surface of the output-side electrode portion 24 is brought into contact with the skin provided with the serum.

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

  The negatively charged ions of the serum are repelled electrically to the negative potential of the output side electrode portion 24 and penetrate deep into the skin. In addition to this, skin stains having a positive potential are electrically sucked and removed by the negative potential of the output side electrode portion 24. Thus, there is an advantage that the serum can penetrate deep into the skin and dirt on the skin can be appropriately removed.

  In this negative-side pattern, a negative current is applied to allow a negatively charged ion of the serum to penetrate, and a short pause is provided in the middle of the DC current to supply the DC current again. Generally, when a direct current is supplied, the electric repulsion immediately after the application of the direct current is the strongest and the power gradually decreases. In this current pattern, since a short pause period is provided and the rising current is provided again, the introduction of ions can be further promoted as compared with the case where a constant DC current is continuously applied.

  Here, in the state where a negative DC current is applied, the negatively-charged ions of the essence penetrate into the skin by electric repulsion as described above, and the positively-charged ions inside the skin as described above. Are combined, so that the number of negatively charged ions of the serum and the number of positively charged ions inside the skin are balanced. That is, the negatively charged ions of the serum do not penetrate. However, in the negative pattern, an alternating current is applied after the intermittent direct current. Since this alternating current switches the output side electrode portion 24 between minus and plus, the above-mentioned balance is broken again, and ions can be permeated again by the subsequent intermittent direct current.

  Next, a case where ion introduction is performed according to the positive pattern shown in FIG. 3 will be described. The positively charged ions of the serum are repelled electrically to the positive potential of the output side electrode portion 24 and penetrate deep into the skin. Thereby, there is an effect that the serum penetrates deep into the skin.

  In this positive pattern, a positive current is applied, and a small pause is provided in the middle of the DC current while the positively charged ions of the serum are infiltrated, and the DC current is applied again. As in the case of the negative side pattern, since the rising current is provided again by providing a short rest period, the introduction of ions can be further promoted as compared with the case where a constant DC current is continuously applied.

  Here, in a state where a positive direct current is applied, ions having a positive potential of the serum as described above penetrate into the skin by electric repulsion, and ions having a negative potential inside the skin. Are combined, so that the number of positively charged ions of the serum and the number of negatively charged ions inside the skin are balanced. That is, the positively charged ions of the serum do not penetrate. However, in the positive pattern, an alternating current is supplied after the intermittent DC current, as in the negative pattern. The alternating current breaks the above-mentioned balance again, and the subsequent intermittent direct current allows ions to permeate again.

  As described above, in the iontophoretic cosmetic device 10, ion introduction can be further promoted by using an intermittent DC current, and ion stagnation can be suppressed by using a subsequent AC current. This makes it possible to more efficiently penetrate the serum into the skin.

  Furthermore, the iontophoretic device 10 uses both the negative side pattern and the positive side pattern to allow both the positively charged ions and the negatively charged ions of the serum to penetrate deep into the skin. Can be. Therefore, there is an advantage that the serum can be more effectively penetrated into the skin as compared with the case where ion introduction is performed using only one pattern.
