High-efficiency air filter structure for automobile

Abstract

The invention discloses a high-efficiency air filter structure for an automobile, and relates to the technical field of air filters, in particular to the high-efficiency air filter structure for the automobile, which comprises an engine air inlet, a lower fixing frame is movably sleeved in an inner cavity of the engine air inlet, and a filtering shell is movably sleeved in an inner cavity of the lower fixing frame. A filter element is fixedly sleeved with an inner cavity of the filtering shell, and a connecting groove is formed in the top of the lower fixing frame. According to the high-efficiency air filter structure for the automobile, through the arrangement of the lower fixing frame, the connecting groove is formed in an inner cavity of the lower fixing frame, the front side and the rear side of the lower fixing frame are connected with the fixing blocks through the fixing springs, the upper fixing frame is arranged above the lower fixing frame, the connecting frame is installed on the bottom face of the upper fixing frame, and the connecting frame is matched with the connecting groove; during use, the filtering shell is conveniently fixed through cooperation of the lower fixing frame and the upper fixing frame, and the situation that dust and gravel enter an inner cavity of an air inlet of an engine due to the fact that a gap exists between the filtering shell and the lower fixing frame is prevented.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to a high-efficiency air filter structure for automobiles. Background technique [0002] The car air filter is an item that removes particulate impurities in the air in the car. The car air filter can effectively reduce the pollutants entering the car through the heating, ventilation and air conditioning system, and prevent the inhalation of harmful pollutants. The car air filter The device that is mainly responsible for removing particulate impurities in the air. When piston machines (internal combustion engines, reciprocating compressors, etc.) The filter is composed of two parts, the filter element and the housing. The main requirements of the air filter are high filtration efficiency, low flow resistance, and continuous use for a long period of time without maintenance. The car engine is a very precise part, very small Any impurities will damage the engine. Therefore, befor...

AI Technical Summary

Problems solved by technology

[0003] During the driving process of the car, there will be serious vibration, which will drive the internal components to vibrate. During the vibration process, some parts will become loose, and there will be gaps between the connecting parts. If the connection between the air filter and the engine If there is a gap, the air with serious dust content will be directly sent to the engine, which will affect the service life of the engine. At the same time, the direct clamping connection between the filter structure and the engine will affect the stability of the device. Sharp large stones and gravel will hit the filter paper at a high speed, which will affect the service life of the filter paper for a long time. Therefore, we propose a high-efficiency air filter structure for automobiles
