Self-cleaning air purification device

Abstract

The invention discloses a self-cleaning air purification device. The self-cleaning air purification device comprises a box body, a first filter screen, a second filter screen, a third filter screen and a spraying device. An air inlet is formed in a bottom plate of the box body. A first air outlet and a second air outlet are formed in a top plate of the box body. The bottom surface of the first filter screen is provided with a plurality of first convex hulls. The top surface of the first filter screen is provided with a plurality of first grooves. The bottom surface of the second filter screen is provided with a plurality of second convex hulls. The top surface of the second filter screen is provided with a plurality of second grooves. The top surface of the third filter screen is provided with a plurality of third grooves. Third convex hulls and the third grooves are arranged in a one-to-one correspondence mode. The spraying device is arranged in the box body, located above the third filter screen and comprises a water tank. The water tank does rotary movement relative to the box body. The box body is filled with purification liquid. A water spraying ring formed by a plurality of spray heads is arranged in the circumferential direction of the bottom end of the outer side of the box body. Each spray head is internally provided with a first flow valve. The self-cleaning air purification device can effectively remove solid pollutants in air and also has good removing effects on bacteria, virus and chemical pollutants at the same time.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a self-cleaning air purification device. Background technique [0002] At present, most of the air purifiers on the market only have a simple air filtration function. They absorb dust in the air by generating a high-voltage electrostatic field. Chemical pollutants have no treatment capacity. A small number of air purifiers have adopted the method of adding ozone to sterilize and remove chemical pollutants while filtering, but this has caused the ozone content in the purified air to exceed the standard and cause secondary pollution. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a self-cleaning air purification device. [0004] A self-cleaning air purification device proposed by the present invention includes a box body, a first filter screen, a second filter screen, a third filt...
