The load detection module 3 is used for detecting the load condition of the motor 2, the load detection module 3 detects that the motor 2 is in a no-load state, then the delay module 4 is triggered to delay the preset time and then the switch 1 is triggered to cut off the power supply, so that the situation that the garbage crusher is in normal operation and the load detection module 3 misdetects that the garbage crusher is crushed completely can be avoided, and the power is cut off after the garbage crusher is crushed completely is delayed by the delay module 4 after the preset time.
