The output terminal 30 is provided on one side of the electric wire and the other side of the electric wire is branched into two electric wires so that the connecting device 90 is provided on the branched electric wire, Are coupled to the pair of patches 10, respectively, so that power is output to the patches.

At this time, the present invention is configured to generate and output a power source having an intensity corresponding to bioelectricity.

Bioelectricity is a microscopic electricity generated in the process of reversal of electrode materials due to the chemical action that occurs when various substances are constantly exchanged through the cell membrane during the metabolism of the body.

Bioelectronics is known to have an intensity of about 10 to 80 μA. This bioelectricity increases the amount of ATP production, the basic energy source of life activity, by up to 5 times and enhances permeability of the cell membrane by about 40% , And by inducing the synthesis of proteins and DNA in the body to improve the metabolism and the like, and thus they are used in various fields such as medical practice or beauty.

Accordingly, in order to further enhance the effect of skin movement and skin care by electric stimulation, a power source having a strength corresponding to bioelectrical electricity, that is, having a current value of 10 to 80 μA is generated, ).

The present invention includes the connection signal sensing unit 1, the control unit 2, and the switch unit 3 in order to alternately supply power to the respective output terminals 30 as described above.

The connection signal sensing unit 1 is for sensing the connection of the output terminal 30 to the port 20.

In addition, the port 20 is provided with an electrode having a pair of a positive terminal and a negative terminal. The positive and negative polarities of the positive and negative polarities are operated in accordance with the set frequency. Accordingly, when the output terminal 30 is connected to the port 20, a connection signal is generated by the connection, and the connection signal sensing unit 1 senses the connection signal.

The connection signal may be a signal having an electrical property generated by the connection, and may include, for example, a current having a constant intensity, a voltage, an amplitude, a frequency, or the like.

The switch unit 3 includes a plurality of switches for selectively outputting or interrupting power to the respective ports 20, and the number corresponding to the number of the ports 20 is provided.

The control unit 2 analyzes the connection signal and controls power to be output to the selected port 20. [

The control unit 2 receives the connection signal and analyzes the received connection signal. At this time, the control unit 2 senses the position of the port 20 to which the connection signal is transmitted, And determines the operation period of each switch according to the number of the received connection signals, and controls the operation of the switch unit 3 according to the operation period.

For example, the power supply device may include a first port 20a, a second port 20b, and a third port 20c. In order to supply power to each port 20, a first switch 3a The switch unit 3 includes a first switch 3b and a third switch 3c and an output terminal 30 is connected to the first port 20a and the second port 20b, Are connected.

The connection signal sensing unit 1 senses a connection signal from the first port 20a and the second port 20b and transmits the connection signal to the control unit 2. The control unit 2 transmits the connection signal And determines that the power is outputted to the first port 20a and the second port 20b corresponding to the position.

At the same time, since the number of the connection signals is two, the power to be transmitted to the first port 20a and the second port 20b can be driven at a period of 1/2 T by driving the switch unit 3 .

The first switch 3a is connected for a time of 1/2 T so that power is outputted to the output terminal 30 connected to the first port 20a. At this time, the second port 20b, The second switch 3b and the third switch 3c are controlled to be in an open state so that power is not outputted to the third port 20c and the third port 20c.

The second switch 3b is connected and the power is outputted to the output terminal 30 connected to the second switch 3b for 1/2 T after the first switch 3a is operated. At this time, the first switch 3a and the third switch 3c are controlled to be opened so that power is not outputted to the first port 20a and the third port 20c.

The patch 10a receiving power from the first port 20a and the second port 20b receiving power from the first port 20a are output to the first port 20a and the second port 20b according to the above- The patch 10b supplied with power from the power source 10 does not interfere with the mutual drive, and skin movement and skin care are performed while the intersection operation is performed.

That is, the control unit 2 determines the operation period in units of 1 / nT according to the number of the received connection signals, and adjusts the power to be output to the port 20 in which the connection signal is generated, And controls the switch unit 3 so that the output of the power supply is cut off to the remaining port 20 connected to the selected one of the ports 20 while the power is being output.

The present invention is advantageous in that power is supplied to the patches 10a, 10b, and 10c without interfering with each other as the pairs of patches 10a, 10b, and 10c are operated at an intersection.

Meanwhile, in order to make the appearance of the apparatus more clean and have a cosmetic effect, the battery (not shown) is fixed to the inside of the power supply device, So that it can be formed into an impossible integral form.

R3z is expressed as an arithmetic average for five single roughness depths from R3z1 to R3z5 and the single roughness depth is the vertical distance between the third highest peak and the third deepest curve at a single evaluation distance of the roughness cross section, The lower the wrinkle depth of the skin is, the more wrinkles are improved, and the unit is 탆.

On the other hand, the eye wrinkle improvement ratio (%) was calculated as ((wrinkle change amount after eye use after product use) / ((eye wrinkle wrinkle measurement result before product use)) × 100.

Statistical analysis was performed by paired t-test and independent t-test for comparison of wrinkles before and after use of the product. Statistical analysis was performed using SPSS 18.0 software. All statistical results were considered statistically significant at 5% (p <0.05).

Referring to FIGS. 5 and 6, it can be seen that the values of Ra and R3z are significantly reduced before and after 14 days of use of the product.
