Self-cleaning structure of dust filter cover of vacuum cleaner

Abstract

The invention relates to a self-cleaning structure of a dust filtering cover of a dust collector. The self-cleaning structure is characterized in that a stereoscopic annular fan blade support is added in the dust collector according to the design, a support shaft sleeve is arranged in the center of the top end of the stereoscopic annular fan blade support and is matched with a center shaft correspondingly, and the center shaft is fixed in the center of the end face of the plastic dust filtering cover (referring to figure 5 and figure 6). The stereoscopic annular fan blade support and rotary scrapers surround the plastic dust filtering cover and are driven by high-speed gas flow to rotate around the plastic dust filtering cover; the rotary scrapers made of soft and wear-resistant materials are friction portions at the inner edge of the stereoscopic annular fan blade support and are in slight limited contact with the curved face of a surface layer of the dust filtering cover, and garbage and dust absorbed on the surface layer of the dust filtering cover can be cleaned directly through rotation of the stereoscopic annular fan blade support and the rotary scrapers.

Description

technical field [0001] The invention relates to household appliance vacuum cleaner products, in particular to a self-cleaning structure for a dust filter cover of a vacuum cleaner. Background technique [0002] At present, various vacuum cleaners and vacuum cleaners are sold on the market, which provide certain convenience for people's household cleaning and nursing; however, there are still some unsatisfactory problems in the use of various vacuum cleaners. Places, for example: some vacuum cleaners are in the process of vacuuming, the filter screen is easily absorbed by garbage dust, and the filter screen is absorbed by garbage dust, the gas circulation and flow rate of the vacuum cleaner will be affected, and the gas flow rate of the vacuum cleaner will be affected. The size directly affects the suction power of the vacuum cleaner and its cleaning effect; in order to solve this problem, many previous products have provided a variety of solutions, including manual shrapnel ...
