Description

Vacuum cleaner filter cleaning device

Technical Field

The utility model belongs to the technical field of filter screen cleaning, in particular to a vacuum cleaner filter screen cleaning device.

Background Art

Household vacuum cleaners use the fan impeller to drive the motor at high speed. The blades in the impeller continuously work on the air, so that the air in the impeller gains energy and is discharged from the fan at a very high speed. At the same time, the air in the dust suction part at the front end of the fan continuously replenishes the air in the impeller, causing an instantaneous vacuum to form in the dust suction part, that is, a relatively high negative pressure difference is formed in the dust suction part and the outside atmospheric pressure. Under the action of this negative pressure difference, the garbage and dust near the suction nozzle enter the vacuum cleaner with the air flow. The working process of the filter cloth cleaning machine consists of three processes: water intake, filter cloth washing, and drainage. In the semi-automatic filter cloth cleaning machine, these three processes are controlled by corresponding button switches. In the fully automatic filter cloth cleaning machine, these three processes can be run in sequence.

A Chinese patent with publication number CN108577687A discloses a vacuum cleaner with air filtering function, including a driving support platform, a filter box body is arranged on the driving support platform, a sealing connection cover body is arranged on the filter box body, and the sealing connection cover body connects the antibacterial discharge device with the filter box body; a plurality of running wheels are arranged at the bottom of the driving support platform, a suction bin and a dust box are arranged at the bottom of the driving support platform, and a sweeping brush is arranged at the bottom of the suction bin; a power supply for powering the device and a driving motor powered by the power supply are arranged in the sealing connection cover body; a suction pump is arranged in the antibacterial discharge device; an air mixing chamber and a central axis driven by the driving motor are arranged in the filter box body, at least one filter layer is sleeved on the central axis rod, and an embedded filter screen is arranged on the filter box body. The present invention provides a vacuum cleaner with air filtering function that can realize cleaning and dust removal, rapid filtering, easy regional disassembly and cleaning of the filter element, and has good air purification and sterilization effects.

In the current existing technology, a large amount of dust and impurities will adhere to the surface of the filter after use, and the impurities contain fibers, cloth threads, paper scraps and other impurities. When filtering, these impurities will be superimposed on each other, and the fibers will fix the impurities such as cloth threads and paper scraps together. In addition, the holes of the filter are relatively small, and some fine fibers will pass through the holes. It will be troublesome to flush them manually, and the problem of not being able to quickly flush them out will occur. Moreover, the cleaned impurities will remain inside the cleaning equipment. If they are not cleaned out, they will re-attach to the surface of the filter, causing secondary pollution of the filter.

To this end, the utility model provides a vacuum cleaner filter cleaning device.
