Novel air filter with self-closed type sealing passage

Abstract

The invention relates to a novel air filter with a self-closed type sealing passage. The novel air filter comprises an internal hollow filter body, wherein an air intake grid and an air exhaust grid respectively penetrate through the bottom surface and top surface of the filter body; a horizontal separating plate is arranged at the bottom part of the interior of the filter body; an air ventilationgird penetrates through the separating plate; a cavity is formed between the separating plate and the bottom surface of the filter body; a circuit board is arranged in the cavity; a primary filteringlayer of a filtering net is arranged on the separating plate; a fan and an upper filtering device are sequentially arranged in the filter body from bottom to top through support frames at the inner walls of left side and right side; the four side surfaces of each of the primary filtering layer of the filtering net, the fan and the upper filtering device are respectively sheathed with two horizontal sealing sponge bars, and are attached with the inner wall of the filter body through the sponge bars; a cable line passage is arranged between a support frame at the lower part of the fan and the inner wall of a back plate of the filter body; a cable line of the fan is connected with the circuit board. The novel air filter has the advantages that the sealed air passage is formed in the air filter, the purifying and cleaning efficiency is improved, and the purifying result is better.

Description

technical field [0001] The invention relates to the field of air purifiers, in particular to a novel air filter with a self-closing sealed channel. Background technique [0002] Air purifiers, also known as air cleaners, air fresheners, and purifiers, refer to the ability to absorb, decompose or transform various air pollutants, generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, Allergens, etc., products that effectively improve air cleanliness are mainly divided into household, commercial, industrial, and building. [0003] The inner wall of the air purifier will be fixed with multi-layer filter devices in turn through the support frame structure, because the support frame is horizontal between the two connected filter devices, which will cause the gas to pass through the gap between the support frames, which will cause The result of cleaning the air is not very ideal, and the efficiency of air circulation and purification...
