Air filter

Abstract

The invention discloses an air filter, which consists of an air inlet pipe, an air inlet pipe of an engine, a filter element, an upper shell and a lower shell of the air filter. The upper shell and the lower shell of the air filter are abutted to form a shell of the air filter, and the filter element is fixed at the abutted part of the upper shell and the lower shell of the air filter, wherein an open pore of the upper shell of the air filter is communicated with the air inlet pipe of the engine, and an open pore of the lower shell of the air filter is communicated with the air inlet pipe. The air filter is characterized in that the abutted surface of the upper shell and the lower shell of the air filter is an inclined plane, the included angle of the abutted surface and the horizontal plane is alpha, and the side wall of the upper shell of the air filter is vertical to the abutted surface. The air filter has the advantages that the air filter can avoid blockage of a bent upper part on the side wall of a vehicle body, is favorable for assembly and disassembly of the upper shell of the air filter, so as to replace the filter element conveniently; at the same time, the air filter improves filter area of the filter element, reduces air resistance in the air filter, improves air inlet efficiency, prolongs the service life of the filter element, and prolongs the replacement time of the filter element.

Description

technical field [0001] The invention belongs to the technical field of automobile engine air intake, and in particular relates to an air filter. Background technique [0002] At present, the automotive air filter is composed of an air intake pipe, an engine air intake pipe, an air filter housing and a filter element, such as figure 1 As shown, the upper shell of the air filter and the lower shell of the air filter are connected by bolts to form a square air filter shell. The joint surface of the upper shell of the air filter and the lower shell of the air filter is parallel to the horizontal plane. The upper shell of the air filter communicates with the intake pipe of the engine, and the lower shell of the air filter communicates with the intake pipe. The intake pipe introduces the outside air into the lower chamber. After the filter element cleans the filter residue, the engine intake pipe delivers the clean air to the engine from the upper chamber to provide air for the e...

Problems solved by technology

[0004] However, the disadvantages of the existing air filter for vans are: the limitation of the space of the car body, the area of ​​the filter element of many air filters is very small, the air resistance is large, the air intake efficiency is low, and the life of the filter element is short

The upper shell of the air filter of the van air filter is blocked by the upper bend of the side wall of the vehicle body. It is difficult to assemble and disassemble the upper shell of the air filter, and it is not easy to replace the filter element.
