[0002] The function of a vehicle air filter element is to filter the air entering the engine, prevent dust, sand and other impurities from entering, provide clean air for the engine, and protect the normal operation of the engine. By filtering impurities in the air, they are prevented from damaging the engine, thereby protecting the normal operation of the engine. In addition, the use of the filter element can also improve fuel efficiency and reduce fuel consumption. The existing vehicle air filter element adopts a drawer-type structure. During installation, the air filter element can be pushed into the housing to complete the installation. Since there is a gap between the air filter element and the housing, some air seeps out through the gap. Therefore, a vehicle air filter element with strong sealing performance is proposed.

[0011] The utility model provides a vehicle air filter element with strong sealing performance, which has the following beneficial effects:

[0012] 1. This highly sealed automotive air filter element solves the problem that existing automotive air filter elements adopt a drawer-type structure. During installation, the air filter element can be installed by pushing it into the housing. Due to the gap between the air filter element and the housing, some air leaks through the gap.

[0013] 2. When the air filter element of the vehicle with strong sealing performance needs to be removed, the nut on the threaded rod is connected through the external handle to drive the threaded rod to rotate in the opposite direction. The threaded rod drives the movable rod to slide back along the guide rail on the inner shell through the connecting rod. During this process, the arc-shaped protrusion on the bottom surface of the elastic spring falls back into the groove on the movable rod, and the space between the movable rod and the elastic spring increases, thereby releasing the squeeze on the elastic spring. The elastic spring returns to its original shape and pulls the movable frame to move inward. The movable frame drives the third sealing gasket away from the inner side of the air filter shell. At the same time, the first sealing gasket is separated from the inner side of the air filter shell, thereby facilitating the removal of the vehicle air filter element.

During installation, the air filter element can be installed by pushing it into the housing. Due to the gap between the air filter element and the housing, some air seeps through the gap.

[0024] The specific usage and function of this embodiment: The utility model puts the vehicle air filter element into the air filter housing, and then connects the nut 15 on the threaded rod 6 through the external handle to drive the threaded rod 6 to rotate, and the threaded rod 6 drives the movable rod 8 to slide along the guide rail 10 on the inner housing 2 through the connecting rod 7. During this process, the groove 11 on the movable rod 8 is disengaged from the arc-shaped protrusion on the bottom surface of the elastic spring 12, so that the arc-shaped protrusion on the bottom surface of the elastic spring 12 contacts the top surface of the movable rod 8, and the space between the movable rod 8 and the elastic spring 12 is reduced, thereby squeezing the elastic spring 12, and the elastic spring 12 pushes the movable frame 13 to move outward, and the movable frame 13 pushes the third sealing gasket 16 to fit closely to the inner side of the air filter housing. At the same time, the reaction force is transmitted to the inner housing 2, and the inner The shell 2 pushes the first sealing gasket 5 on the bottom frame 4 to fit tightly against the inner side of the air filter shell. When the air filter element needs to be removed, the nut 15 on the threaded rod 6 is connected through the external handle, thereby driving the threaded rod 6 to rotate in the opposite direction. The threaded rod 6 drives the movable rod 8 to slide back along the guide rail 10 on the inner shell 2 through the connecting rod 7. During this process, the arc-shaped protrusion on the bottom surface of the elastic spring 12 falls back into the groove 11 on the movable rod 8, and the space between the movable rod 8 and the elastic spring 12 increases, thereby releasing the squeeze on the elastic spring 12. The elastic spring 12 returns to its original shape and pulls the movable frame 13 to move inward. The movable frame 13 drives the third sealing gasket 16 away from the inner side of the air filter shell. At the same time, the first sealing gasket 5 is disengaged from the inner side of the air filter shell, thereby facilitating the removal of the vehicle air filter element.
