Abstract

The invention provides a constant current output system, a radio frequency cosmetology instrument and a constant current output method, being applied to a radio frequency cosmetology instrument. The invention comprises the following steps: a current detection unit is used for detecting the output current value of a current stabilization output unit in real time and sending the output current valueto a control unit; the control unit is used for receiving the output current value sent by the current detection unit, comparing the output current value with the preset current threshold value, andadjusting the duty ratio of the output PWM rectangular wave in real time according to the comparison result, so that the current stabilization output unit outputs a constant current according to the control of the PWM rectangular wave. The system of the invention can make the current value output by the current stabilizing output unit constant; after the constant current output system is applied to the radio-frequency cosmetology instrument, the curative effect of the radio-frequency cosmetology instrument can be ensured, the use effect of the radio-frequency cosmetology instrument is improved, the practicability is good, and the technical problems of poor use effect and bad practicability of the existing radio-frequency cosmetology instrument are alleviated.

Description

technical field [0001] The invention relates to the technical field of skin treatment instruments, in particular to a constant current output system, a radio frequency beauty instrument and a constant current output method. Background technique [0002] The radio frequency beauty instrument has the function of removing wrinkles. It contacts with the human skin, and the radio waves emitted enter the subcutaneous tissue, so that the natural resistance movement of the subcutaneous tissue generates heat energy, which has two functions of lifting the skin and promoting collagen regeneration. When the radio wave enters the subcutaneous tissue, the collagen shrinks immediately and stimulates the dermis to secrete new collagen fibers, which in turn increases the thickness and density of the dermis, fills in wrinkles and improves relaxation. [0003] When the existing radio frequency beauty instrument acts on the human skin, the impedance of the human body (that is, the resistance va...
