Air inlet passage water filtering device

Abstract

The invention discloses an air inlet passage water filtering device which comprises an air inlet, an air outlet, a filtering chamber and a drainage opening, wherein the filtering chamber is of a chamber structure, and the air inlet and the air outlet are respectively formed in the two ends of the filtering chamber; the cross-sectional area of the filtering chamber is larger than the cross-sectional areas of the air inlets and the air outlets; the drainage opening is formed in the bottom of the filtering chamber and connected with a drainage pipe with a long and thin structure; a fixing lug is arranged at the outer part of the filtering chamber, and a mounting is formed in the fixing lug; the filtering chamber is horizontally mounted at the front end of an air inlet of an air filter through the mounting hole, and the air inlet and the air outlet are connected to an air inlet pipeline through hoses. The air inlet passage water filtering device is simple in structure and convenient to manufacture and mount, can effectively filter moisture in the air, and ensures that dry and clean air enters an engine through the air filter. By adopting the structure, the air inlet resistance of an air inlet system is not increased.

Description

technical field [0001] The invention relates to an intake channel water filter device, which is used in the intake system of a commercial vehicle and belongs to the technical field of automobile manufacturing. Background technique [0002] The air filter element mostly uses paper filter material, which will cause the filter element to swell after wading, causing the filter element to collapse, suck and other problems. At present, in order to prevent moisture from entering, devices such as louvers or swirl tubes are usually installed at the inlet of the air intake to realize the separation function, but there will still be some moisture, especially when the engine is running at full load, enters the air intake system pipe with the airflow, and finally enters the air. The filter renders the cartridge unusable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an air intake channel water filter device for the defects...

[0002] Air filter elements mostly use paper filter material, which will swell after wading in water, causing the filter element to collapse, suck and other problems

At present, in order to prevent moisture from entering, devices such as louvers or swirl tubes are usually installed at the inlet of the air intake to realize the separation function, but there will still be some moisture, especially when the engine is running at full load, enters the air intake system pipe with the airflow, and finally enters the air. The filter makes the filter element unusable
