Abstract
The utility model discloses an air filter, which belongs to the field of air filters and comprises an outer shell, a shell cover and an air filter body, an arranged connecting mechanism is matched with the air filter body for use, when the air filter body is placed in the outer shell, connecting blocks on two sides of an air outlet are aligned with positioning ports on a connecting sleeve, and then the air filter body is connected with the shell cover. The air filter body is pushed to enable the air outlet to extrude the movable ring in the connecting sleeve, the movable ring moves upwards along the connecting hole in the fixed ring through the movable rod and forces the compression spring to perform retraction operation until the air filter body cannot be pushed, the air filter body is rotated, and the connecting block enters the rotating opening and cannot rotate, so that the air filter body is pushed to be closed. The air filter body is loosened to enable the compression spring to conduct stretching recovery operation, the air outlet is pushed downwards through the movable ring, the connecting block is clamped into the limiting opening, finally, the shell cover is screwed into the bottom of the outer shell through the handle, and therefore the air filter body can be rapidly installed in the outer shell.
