Problems solved by technology

[0002] At present, many air filter assemblies have the problem of reciprocating disassembly and assembly within the maintenance mileage, mainly to remove the dust adhering to the surface of the filter element, resulting in the need to stop the vehicle for manual cleaning at any time during operation;
[0003] Another problem is that if the filter assembly does not contain a fixed swirl plate or an air inlet baffle, one part of the filter element of the filter assembly will be damaged by airflow impact for a long time, making the life of the entire filter element severely shortened;
[0004] The current air filter assembly is fixed by the filter element, and the design of multiple dust removal during the manual maintenance cycle makes the whole maintenance process difficult. The installation position of the air filter assembly on the vehicle is also restricted. Too high or too hidden, only in the 4S shop for maintenance or replacement of end-of-life filter elements

Abstract

The invention relates to a spin-type air filter device. The spin-type air filter device comprises an upper end cover assembly, a spinning disk, a main filter element assembly, a safety filter elementassembly and a lower end cover assembly; the upper end cover assembly is connected with the lower end cover assembly through a buckle to form a shell body, and an air inlet and an air outlet are formed in the lower end cover assembly; the main filter element assembly is installed in the shell body, an upper end cover of the main filter element assembly is installed in a rotating ring groove in theupper end cover assembly, and a lower end cover of the main filter element assembly is installed in a rotating ring groove in the lower end cover assembly; a filter element upper end cover of the safety filter element assembly is installed in a rotating ring groove of the upper part of the main filter element assembly, and the lower end of the safety filter element assembly is fixedly connected with the air outlet; and the spinning disk is detachably installed on the outer part of the main filter element assembly in a sleeving mode. Compared with the prior art, the spinning disk is added, thus the main filter element assembly can rotate by self under the drive of the air in the air inlet, the effects of dust discharge and ash removal are achieved through the centrifugal force of the mainfilter element assembly, and the advantages of long service life and convenient disassembly and assembly are achieved.
