Apparatus and method for controlling output of skin care beauty device

Abstract

Disclosed is an apparatus for controlling the output of a skin care beauty device, which can reduce peak power to be output to the skin, by suppressing a sudden current change when direct current voltage is converted into alternating current voltage. The disclosed apparatus for controlling the output of a skin care beauty device: amplifies direct current voltage and outputs same; converts the output direct current voltage into alternating current voltage with a set frequency and outputs same to a pair of contact electrodes; and senses the current flowing through the skin according to changes in the resistance of the skin to which the alternating current voltage is applied, so as to control the amplification of the direct current voltage.

Description

technical field [0001] The present disclosure relates to a skin care device, and more particularly, to an apparatus and method for controlling an output of a skin care device that cares the skin by applying high-frequency current to the skin. Background technique [0002] Generally, skin care devices can be classified into skin care devices that transmit ultrasonic waves to a user's skin (hereinafter, ultrasonic type skin care devices) and skin care devices that apply electric current (hereinafter, current type skin care devices). [0003] Ultrasonic skin care instruments massage the skin through the physical vibration of ultrasonic waves. The current type skin care device applies a microcurrent to the user's skin to remove sebum, waste, etc. or to cause skin nutrients to be deeply absorbed into the skin. [0004] Amperometric skin care devices apply high-frequency current to the skin. The electric current output from the skin care device is applied to the dermis of the sk...

AI Technical Summary

Problems solved by technology

There is a problem that due to the increase in the temperature of the dermis, the user will feel hot or in severe cases the user's skin will be burned

However, there is a problem that conventional electric current type skin care devices have reduced skin care efficacy because the skin temperature changes drastically when the power is turned on or off, and it is difficult to accurately measure the temperature of the dermis

However, there is a problem that since the skin care instrument is placed close to the human body, electromagnetic waves affect the human body, and it is difficult to maintain the current applied to the skin at a set frequency, thereby reducing the skin care efficacy

[0009] In addition, there is a problem that conventional current-type skin care instruments output pulse-width-modulated alternating current power (alternating current), so that high power (current) is instantaneously applied to the skin at peak power

At this time, since high power (current) is instantaneously applied to the skin, the user may feel burning or stinging, or may be electrocuted in severe cases
