[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In this embodiment, an easily replaceable automobile air filter includes a shell 1, a cover 2 is movably installed on the top of the shell 1, a filter element 3 is installed inside the shell 1, an air inlet pipe 4 is fixedly installed inside the cover 2, an air outlet pipe 5 is fixedly installed on the bottom of the shell 1, and a replacement component 7 is installed inside the shell 1.

[0022] It should be noted that the car air filter is an item that removes particulate impurities in the air inside the car. It can effectively reduce the pollutants that enter the car through the heating, ventilation and air-conditioning system and prevent the inhalation of pollutants that are harmful to the body. The car air filter is composed of a shell 1, a cover 2, a filter element 3, an air inlet pipe 4 and an air outlet pipe 5 to achieve air filtration, among which the filter element 3 is the main filtering part and is responsible for gas filtering, while the shell 1 is an external structure that provides necessary protection for the filter element 3.

[0023] The replacement component 7 includes two movable grooves 701 opened inside the shell 1, and push rods 702 are movably installed inside the two movable grooves 701, and T-shaped plates 703 are fixedly installed on the opposite sides of the two push rods 702. Two No. 1 return springs 704 are fixedly installed on the inner walls of the two movable grooves 701, and U-shaped plates 705 are fixedly installed on the opposite sides of the two T-shaped plates 703. Two grooves 706 are opened inside the cover 2, and two movable plates 707 are slidably installed on the inner walls of the two grooves 706, and a No. 2 return spring 708 is fixedly installed between every two movable plates 707.

[0024] Specifically, when replacing the filter element 3, the two push rods 702 are pushed toward the opposite side, and the two push rods 702 drive the U-shaped plate 705 to move through the T-shaped plate 703. The movement of the U-shaped plate 705 pushes the two movable plates 707 to squeeze the No. 2 return spring 708, so that the movable plate 707 is located in the groove 706, and the cover 2 and the filter element 3 are pulled upwards respectively to realize the replacement of the filter element 3.

[0025] A sealing gasket 6 is fixedly mounted on the inner wall of the housing 1 .

[0026] Specifically, the sealing gasket 6 can increase the sealing performance between the cover 2 and the housing 1, thereby preventing leakage of the air filter.

[0027] Two limit rods are fixedly mounted on the top and bottom of the filter element 3, and the inner bottom wall of the housing 1 and the bottom of the cover 2 are respectively provided with limit grooves adapted to the two limit rods, and both sets of limit rods extend into the limit grooves.

[0028] Specifically, the limiting groove and the limiting rod can limit the filter element 3 so that the filter element 3 can be stably installed in the housing 1.

[0029] The two sets of movable plates 707 are extended to the inside of the movable groove 701 , and the two sets of movable plates 707 and one end of the two U-shaped plates 705 are respectively provided with inclined surfaces, and the movable plates 707 are correspondingly pressed and matched with the inclined surfaces of the U-shaped plates 705 .

[0030] Specifically, when the U-shaped plate 705 moves, the inclined surface on the U-shaped plate 705 is used to push the movable plate 707 so that the two movable plates 707 are close to each other.

[0031] In summary, the easily replaceable automobile air filter is configured by the coordination between the housing 1, the cover 2, the filter element 3, the air inlet pipe 4 and the air outlet pipe 5. Air enters the housing 1 through the air inlet pipe 4, is filtered and adsorbed by the filter element 3, and the filtered air is then transported to the engine through the air outlet pipe 5. The sealing gasket 6 is configured to increase the sealing between the cover 2 and the housing 1, thereby avoiding leakage of the air filter.

[0032] In addition, by setting up the replacement component 7, when replacing the filter element 3, the two push rods 702 are pushed to the opposite side, and the two push rods 702 drive the U-shaped plate 705 to move through the T-shaped plate 703. The movement of the U-shaped plate 705 pushes the two movable plates 707 to squeeze the No. 2 return spring 708, so that the movable plate 707 is located in the groove 706, so that the cover 2 is separated from the shell 1, and the cover 2 and the filter element 3 are pulled upwards respectively to realize the replacement of the filter element 3.
