Self-cleaning air filter

Abstract

The invention discloses a self-cleaning air filter. The self-cleaning air filter comprises a cylinder shell; a rotation disk is arranged in the cylinder shell; the other end of the cylinder shell is provided with a gear ring; a paper filter element is arranged between the rotation disk and the gear ring; a safe filter element is arranged in the paper filter element and is directly pressed against two end covers of the cylinder shell; an air inlet is formed on an upper wall of the cylinder shell; an air outlet is formed in the middle of each end cover against which the safe filter element is pressed; a small motor is arranged beside the gear ring; a spiral gas ejector pipe is arranged on one side of the paper filter element; a micro spray office is formed on the spiral gas ejector pipe facing the direction of the paper filter element; and the lower part of the cylinder shell is provided with at least one dust discharge hole. In the self-cleaning air filter, double filter elements guarantee the quality of filtered air and ensure that clean air enters an engine; and a rotator paper filter element can be started and rotated after flameout so as to throw away dust on the rotatory paper filter element; and if air is fed into the spiral gas ejector pipe, the dust on the surface of the paper filter element can be cleaned further. The self-cleaning of the air filter is realized, the work amount of daily maintenance of engines of engineering vehicles is reduced, and the engineering vehicles can be used normally.

Description

technical field [0001] The invention relates to an automobile engine air intake filter technology, in particular to a self-cleaning air filter. Background technique [0002] All drivers know that the air filter on the car engine needs to be cleaned frequently. This is already common sense and should be unshakable. The air filter that is not cleaned frequently hinders the normal intake of engine air, directly affects the output power of the engine, and in severe cases will cause the problem of insufficient engine power. Large-scale engineering vehicles often work in a dusty working environment, and it is necessary to clean the car air filter regularly, which has become a necessary procedure for engineering vehicles. Although the cleaning of the air filter is not a high-tech and difficult job, due to the excessive dust on the project site, the air filter must be cleaned almost every day, which has become a considerable workload and has become a major task for engineering vehi...
