Underarm odor treatment device circuit diagram

Underarm odor is a product of bacterial mold. Ozone has the functions of sterilization, deodorization and mildew prevention, and its use in treating underarm odor has a certain effect. In this circuit, IC1 (M5232) forms a voltage detection and battery under-voltage automatic shutdown circuit. F3 and F4 form a 12kHz oscillator , which is modulated by the low-frequency oscillator composed of F1 and F2. Adjusting RP can make the working intermittent time continuous between 0 and 20s. Adjustable. When the battery voltage is greater than 4.2V, the LED lights up, pin 6 of M5232 outputs low level , the oscillation circuit starts to work, and drives the ozone generation circuit through V2 and V3 . When the battery voltage is less than 4.2V, pin 6 of M5232 outputs a high level , the oscillator stops vibrating and the ozone generating circuit is closed . At the same time, the indicator light flashes to remind you to replace the battery.

The circuit of the armpit odor treatment device is shown in the figure:
