Description

technical field [0001] The invention relates to the field of vacuum cleaners, in particular to a zero-power consumption protection circuit for vacuum cleaners and a protection method thereof. Background technique [0002] Vacuum cleaners are cleaning equipment widely used in advanced human life and industrial production. It has been developed for more than 100 years since its birth. The working principle of the vacuum cleaner is to use the motor to drive the blades to rotate at high speed, generate air negative pressure in the sealed housing, and then suck the dust through the external suction pipe. [0003] In some current rechargeable vacuum cleaners, the circuit will continue to consume the power of the battery pack for a period of time after the power is turned off, and the zero power consumption of the circuit cannot be realized immediately, thus wasting the power of the battery. Contents of the invention [0004] In view of this, the present invention provides a zer...
