Optionally, switch 303 is a normally closed switch.

Specifically, the switch 303 is a normally closed switch, and the switch 303 is turned off when power is supplied and turned on when power is lost, so that when the electric quantity of the power supply module 301 is greater than or equal to a preset electric quantity, the switch 303 is turned on and turned off, so that the connection between the battery 100 and the host module 302 is disconnected, and the power supply module 301 supplies power to the host module 302; when the electric quantity of the power module 301 is less than the preset electric quantity, the electric quantity of the power module 301 is not enough to power on the switch 303, so that the switch 303 is powered off and closed, the battery 100 is connected with the power supply end of the host module 302, and the battery 100 supplies power to the host module 302.
