Problems solved by technology

At present, in order to provide sufficient air for engine combustion, reduce the wear and tear of dust in the air on the engine block, and reduce noise, the usual practice is to add an air filter device before the engine intake, and reduce air impurities through the air filter device. Particles enter the engine to protect the engine. The air filter used in general cars is a dry filter. The dry filter is mainly composed of a filter element and a housing. The filter element is the main component, but the car is running During the process, it often shakes. If the connection between the filter element and the housing is unstable, it will cause damage to the filter element. At the same time, the filter element filters impurities in the air for a long time, and the interior also contains a large amount of dust powder.

Abstract

The invention discloses an air filter with a filter element fixedly conveniently, which comprises a shell, wherein one end in the shell is fixedly connected with a connecting block; one side of the connecting block, away from the shell, is provided with a groove I; one end of the filter element is positioned in the groove I; the two sides of one end of the filter element, which is positioned in the groove I, are provided with grooves II; the portion, where the groove I is close to the grooves II, is provided with a groove III; a moving block is arranged in the groove III; one side of the moving block is fixedly connected to a lug; one side of the moving block, away from the lug, is fixedly connected with the groove III through a plurality of springs I; one side of the moving block, close to the springs I, is fixedly connected with a connecting rod; one side of the moving block, away from the filter element, is provided with a cavity; a through hole is formed in the shell, near the cavity, and an end of the connecting rod, away from the moving block penetrates the cavity and is located in the through hole. The air filter with the filter element fixedly conveniently has the advantages that the filter element and the shell can be connected and fixed, and dust in the filter element can be removed.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to an air filter which is convenient for fixing a filter element. Background technique [0002] Automobiles have generally been closely linked with people's lives, and the development of the automobile industry is also getting faster and faster. Followed by people more and more attention to the power, economy, environmental performance of the car. The intake system provides clean air for the engine. The performance of the intake system plays an important role in improving the power and economy of the engine and prolonging the service life of the engine. At present, in order to provide sufficient air for engine combustion, reduce the wear and tear of dust in the air on the engine block, and reduce noise, the usual practice is to add an air filter device before the engine intake, and reduce air impurities through the air filter device. Particles enter the engine to protect th...
