Description

Technical Field

[0001] The utility model relates to the technical field of air filter element fixing, in particular to a fixing support device for an air filter element. Background Art

[0002] The air filter element can effectively filter the dust in the air. The engine needs to inhale a large amount of air during operation. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Large particles entering between the piston and the cylinder will cause serious "cylinder pulling", which is particularly serious in dry and sandy working environments. The air filter is installed in front of the carburetor or the intake pipe to filter out dust and sand in the air and ensure that sufficient and clean air enters the cylinder. When installing the air filter element, it is often necessary to use a fixed support device to support and fix the air filter element for use.

[0003] The air filter element fixing support device in the prior art, in actual use, the outer shell and the cover plate of the fixing support device are usually fixed with multiple screws. When the air filter element needs to be replaced, multiple screws need to be removed to remove the air filter element for replacement. The operation is cumbersome and laborious, which affects the efficiency of disassembling and replacing the air filter element. Therefore, we propose a fixing support device for an air filter element to solve the above-mentioned problems. Utility Model Content
