An air filter for an engine with a detachable filter element

Abstract

The invention provides an engine-used air filter with filter elements detachable. The air filter comprises a first filter body, a second filter body and a third filter body. The first filter body, the second filter body and the third filter body are each of a barrel structure with the two ends openable. An annular check ring is arranged on the inner wall of the first filter body. The first filter element is detachably mounted in the annular check ring. One end of the second filter body extends into the first filter body and is clamped into a first annular clamping groove. The other end of the second filter body is in threaded connection with a first end cover. The second filter element is arranged in the second filter body. The interior of the second filter body is partitioned into a first filter chamber and a second filter chamber through the second filter element. An air inlet is formed in the first end cover. One end of the third filter body extends into the first filter body and is clamped into a third annular clamping groove. The other end of the third filter body is in threaded connection with a second end cover. The third filter element is arranged in the third filter body. An air outlet is formed in the second end cover. According to the engine-used air filter, air is filtered through multiple channels; impurities in the air can be thoroughly filtered out; and air filtering efficiency and filtering cleanliness are improved.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to an engine air filter with a detachable filter element. 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 fixed and cannot be disassembled. After long-term use, the impurities on the filter element are not easy to clean, and it is not easy to replace the filter element. Contents of ...
