Problems solved by technology

For commercial vehicles, due to the influence of structural strength and performance indicators, the filter element structure is usually cylindrical, and the air filter is generally cylindrical, and the air inlet and outlet are arranged vertically. However, if the air inlet and outlet are required to be arranged on the same side and the air filter is shaped , the current air filter cannot meet the requirements

Embodiment Construction

[0021] Such as Figure 1-6 As shown, the air filter of the present invention includes a housing 1 , a cover 2 , a filter element 3 and a filter element guide rail 4 , wherein the filter element 3 includes a filter element splint 31 , filter paper 32 , filter element cover 33 and a sealing strip 34 . The housing 1 , the filter element 3 and the filter element guide rail 4 cooperate to realize the fixing, sealing, assembly and disassembly of the filter element 3 .

[0022] In order to ensure assembly reliability, the cover 2 is provided with an anti-stripping rib 21 supporting the filter element guide rail 4, so as to prevent the filter element 3 from being poorly sealed when the filter element guide rail 4 falls off and affecting the filtration performance of the air filter.

[0023] The first support surface 11 provided on the housing 1 and the second support surface 331 provided by the filter element cover plate 33 form an up and down movement space for the filter element gui...

Abstract

The invention provides an air filter and a sealing method thereof, wherein an air inlet and an air outlet are arranged at the same side of the air filter. The air filter comprises a shell body, a cover, a filter cartridge and a filter cartridge guide rail. The filter cartridge comprises a filter cartridge splint and a filter cartridge cover plate. The fixing, sealing, assembly and disassembly of the filter cartridge are achieved by the coordination between the shell body, the filter cartridge and the filter cartridge guide rail. According to the air filter, the air filter is provided with the filter cartridge guide rail similar to a cam structure, the sealing and fixing of the filter cartridge are achieved through the compression surface formed by the shell body and the filter cartridge cover plate and can be applied to the air filter and the sealing method both constrained by space layout, and changing and installation of the filter cartridge are convenient.

Description

technical field [0001] The invention relates to an air filter device for a commercial vehicle, in particular to an air filter with air inlet and outlet on the same side and a sealing method thereof. Background technique [0002] The traditional car air filter element is cylindrical or flat, and its sealing structure is sealed by the compression force after the shell and cover are assembled. For commercial vehicles, due to the influence of structural strength and performance indicators, the filter element structure is usually cylindrical, and the air filter is generally cylindrical, and the air inlet and outlet are arranged vertically. However, if the air inlet and outlet are required to be arranged on the same side and the air filter is shaped , the current air filter cannot meet the requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an air filter with air inlet and outlet arranged on the same side an...
