Automobile air filter assembly

Abstract

The invention discloses an automobile air filter assembly which comprises a filter housing sub assembly. A filter element assembly is arranged in the filter housing sub assembly and comprises a filterelement assembly frame box adaptive to the inner surface of the filter housing sub assembly; multiple folded filter paper is horizontally arranged on the inner surface of the filter element assemblyframe box at intervals; a slotted hole is formed in the position, between each two adjacent folded filter paper, on the bottom part of the filter element assembly frame box; a communication pipe is arranged at the position, located on the filter element assembly frame box, on the bottom part of the filter housing sub assembly; the inner surfaces of the slotted holes communicate with the communication pipe; and an air pump communicates to one end, far away from the filter element assembly frame box, of the communicating pipe. According to the automobile air filter assembly provided by the invention, a controller controls an electromagnetic valve to turn on and then controls the air pump to work, dust attached to one sides, close to each other, of the folded filter paper is discharged through the air pump from the slotted holes and the communication pipe, the controller controls the electromagnetic valve to turn off after the treatment is accomplished, and the cyclic operation is carriedout at time intervals, so that the problems existed in the background technology can be effectively solved.

AI Technical Summary

Problems solved by technology

An air outlet pipe is connected above the filter housing sub-assembly, a dust cover is provided on one side of the filter housing sub-assembly, and an air intake pipe is connected through the dust cover. The other end of the housing sub-assembly is provided with a mounting bracket, the lower part of the filter housing sub-assembly is provided with a dust discharge valve, and the inside of the filter housing sub-assembly is sequentially provided with a safety filter sub-assembly , outer filter element sub-assembly, swirl cover, the swirl cover forms a passage with the dust cover, which solves the problem that the air directly enters the filter element through pressure after entering, and fails to make full use of the structure of the air filter, resulting in additional Problems of wasting energy and consuming costs

[0003] The filter element of the above-mentioned filter is used for a long time and the dust will block the filter element hole, resulting in a decrease in the passing effect. For this reason, in order to improve the service life and use effect of the filter element, the filter element and the filter element housing of the prior art are improved, and a filter element housing is provided.
