The flip-flop includes a data input pin, a clock pin, and a true flip-flop output pin. The reset switch is connected to the data input pin, the first power supply module is connected to the clock pin, and the true flip-flop output pin is connected to the CPU. The reset switch generates a low-level reset signal when being pressed; the flip-flop receives an electrical signal from the clock pin. A rising edge of the electrical signal triggers the flip-flop to latch a low-level state of the reset signal. The flip-flop outputs a low-level reset request signal from the true flip-flop output pin according to the latched low-level state of the reset signal. The CPU starts a factory reset operation according to the reset request signal.
