Document Type and Number:
WIPO Patent Application WO/2022/121331
Kind Code:
A1
Abstract:
A self-cleaning method and apparatus (100) for a vacuum cleaner, and a vacuum cleaner. The method comprises: according to a received self-cleaning instruction, determining a self-cleaning rotation speed mode of a fan of a vacuum cleaner, wherein the self-cleaning rotation speed mode is used to enable a filter and a dust collection box of the vacuum cleaner to vibrate under the rotation of the fan (S10); and continuously adjusting the rotation speed of the fan multiple times according to the self-cleaning rotation speed mode, wherein each adjustment at least comprises reducing the rotation speed of the fan and increasing the rotation speed of the fan to a target rotation speed (S20). By means of continuously adjusting the rotation speed of a fan multiple times, the air pressure in an air duct within an air intake end of a vacuum cleaner can continuously change, so as to cause a filter and a dust collection box to vibrate, thereby facilitating dust attached to the filter and the dust collection box to be shaken off.
