Air purifying system

Abstract

The invention provides an air purifying system. The system comprises a shell, a filter screen mechanism, a negative pressure generator, a first detector, a second detector, a third detector and a controller, wherein the shell is internally provided with a first cavity and a second cavity which are communicated, the filter screen mechanism is arranged in the first cavity, the filter screen mechanism comprises an outer frame, a filter screen with a periphery connected with the inner side of the outer frame, and a dust removal device for removing dust on the filter screen, the dust removal devicecomprises a first guiding rail, a dust removal assembly, a first driving mechanism and a second driving mechanism, the negative pressure generator is arranged in the second cavity, and the controlleris connected with the first driving mechanism, the second driving mechanism, the dust removal assembly, the first detector, the second detector, the third detector and the negative pressure generator, and controls action of the first driving mechanism, the second driving mechanism, the dust removal assembly, the first detector, the second detector, the third detector and the negative pressure generator. According to the air purifying system, by arranging the dust removal device on the filter screen to remove the dust on the filter screen, dust accumulation is prevented.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification system. Background technique [0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc.), products that effectively improve air cleanliness. [0003] However, after the above-mentioned air purifier is used for a long time, a large amount of dust will accumulate on the filter screen of the air purifier, which will affect the filtering effect. When the filter screen needs to be cleaned, the primary filter screen needs to be disassembled and taken out at first. This process is time-consuming, so this problem needs to be solved. Contents of the invention [0004] Based on the technical problems existing in the background technology, the pre...
