[0014] The utility model has the following beneficial effects:

[0015] 1. Through the design of the brush plate and the driving mechanism, the dust on the surface of the filter can be cleaned by the rotation of the brush plate, which effectively avoids the clogging of the filter and ensures the filtering effect of the filter;

[0016] 2. Through the setting of the dust suction mechanism, the dust is sucked into the vacuum cleaner during the rotation of the brush plate, which further improves the cleaning effect of the filter, prevents the dust from flying and affecting the surrounding environment, and prevents the dust from remaining near the filter and being re-absorbed onto the filter surface, resulting in poor cleaning effect.
