Abstract
A power-saving control device for operation of an electronic garbage can includes a rotation-blocked current setting register, a sampling resistor, an analog-digital converter, an analog-digital conversion result register, and a comparing unit, which are electrically connected in sequence. The comparing unit compares a current value obtained in real time with a reference current value in the rotation-blocked current setting register, and when the real-time current value is greater than the reference current value, the microcomputer control unit stops supplying power to a motor by controlling the motor positive and negative rotation driving circuit. The power-saving control device has greatly reduced power consumption during operation of an electronic garbage can and a prolonged service life of its battery.
