Air filter for multi-level efficient engine

Abstract

The present invention provides a multi-stage high-efficiency engine air filter, comprising a first filter body, a second filter body, a third filter body, a plurality of first filter elements, a second filter element, a third filter element, and a first filter body. The openings at both ends are respectively screwed with a first end cover and a second end cover. The second filter body is a cylinder structure with both ends open; the third filter body is a cylinder structure with one end open and one end closed. The body is arranged in the first filter body and the cover is arranged outside the second filter body; a plurality of first filter elements are arranged in parallel in the first filter body, and the second filter body is provided with a rotating shaft arranged coaxially with it, and the plurality of first filter elements pass through The rotating shaft is installed in the second filter body and can rotate with the rotation of the rotating shaft; the second filter element is arranged in the third filter body and is sleeved on the outside of the second filter body; the third filter element is arranged in the first filter body and sleeved in the third filter body outside of the filter. The present invention can completely filter out impurities in the air by performing multi-channel filtration on the air, thereby improving the filtration efficiency of the air and the cleanliness of the filtration.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to a multi-stage high-efficiency engine air filter. Background technique [0002] In order for the engine to function properly, a large amount of pure air must be drawn in. If substances harmful to the engine in the air are inhaled, the cylinder and piston components will increase the burden, causing abnormal wear and tear, and even mixing with engine oil, causing greater wear and tear, resulting in deterioration of engine performance and shortened life. The role of the car air filter is to provide clean air for the engine to prevent the engine from inhaling air with impurity particles and causing wear and tear. At present, most of the air filter elements on the air filter used by the engine are composed of a sealing ring, an upper end cover, an outer protection net, a filter paper, an inner protection net and a lower end cover lamp. Most of the existing inner and outer protect...

Problems solved by technology

At present, most of the air filter elements on the air filter used by the engine are composed of a sealing ring, an upper end cover, an outer protection net, a filter paper, an inner protection net and a lower end cover lamp. Most of the existing inner and outer protection nets are made of The most important thing is to weld the connection mesh or vertically bite the mesh. The mesh of this structure is easy to cause waste of raw materials when cutting, and cannot completely filter out the particles in the air. The efficiency is low. After long-term use, the impurities on the filter element Not easy to clean
