the charge protection circuit part: MicroUSB supplies voltage VCC for a charging part circuit through an adapter or a USB power supply, and carries out constant current/constant voltage linear charging on a lithium battery through a PL4054 lithium battery charging IC. The charging voltage is positively input into VCC (pin 4), then the BAT (pin 3) adjusts the float charging voltage to 4.2V, and the float charging voltage is connected to the anode of the battery to charge the lithium battery; PL4054 supplies current for different stages of charging to charge the lithium battery when the voltage of the lithium battery is lower than the float voltage (the current value is determined by the resistance value of PROG (pin 5)), at which time the CHRG (pin 1) is pulled low and the charge status indicator light (D1) is lit. When the voltage of VBAT (pin 3) rises to 4.2V, and finally the charging cycle is over, CHRG (pin 1) is in high impedance state, the charge status indicator lamp (D1) is off, and PL4054 is in shutdown mode.
The singlechip control part: under the normal operating mode, the lithium battery provides power for the circuit board, and the DW06 lithium battery protection IC is adopted to prevent the situations of overcharge, overdischarge, overcurrent, short circuit and the like. VDD (pin 5) is used for detecting the positive pole voltage of lithium cell, and when VDD voltage is less than 2.5V, the inside MOS pipe of IC switches on, and lithium cell negative pole (VBAT-) switches on with GND, and battery positive pole (VBAT) switches on with the GND return circuit (the same reason charges).

In the power-on mode, long-time pressing of the tact switch (SW1)3S turns off the LED, the motor stops working, and the single chip microcomputer enters a low power consumption mode.
