[0001] The utility model relates to the field of filters, in particular to an air filter which is easy to assemble. Background Art

[0002] A filter is an accessory that filters impurities or gases through filter paper, generally referring to an automobile filter, which is an engine accessory. An air filter includes a housing and a filter element in the housing. During the production and assembly of an air filter, end caps need to be installed at both ends of the filter element. The end caps at both ends of the filter element are fixed to the filter element by glue. After the end caps are fixed to both ends of the filter element by glue, they need to be moved to the next station for assembly via a conveyor belt. At this time, the glue that fixes the end caps is not completely dry, and it is inevitable that the filter element will bump during movement. The bumps will loosen the end caps, resulting in loose connection of the end caps, which reduces product quality. Therefore, an air filter that is easy to assemble is proposed. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1 As shown, an air filter that is easy to assemble includes an annular filter element 2, an upper end cover 1 is provided at the upper end of the annular filter element 2, a lower end cover 3 is provided at the lower end of the annular filter element 2, docking markings 4 are provided on the side walls of the upper end cover 1 and the lower end cover 3, and the docking markings 4 on the upper end cover 1 and the lower end cover 3 are aligned in the vertical direction, a connecting mechanism 5 is provided on the upper end cover 1, and a limiting mechanism 6 is provided in the lower end cover 3. Through the cooperation of the connecting mechanism 5 and the limiting mechanism 6, the lower end cover 1 and the upper end cover 3 can be kept stably connected to the annular filter element 2 when the glue is not completely dry, so as to prevent the end covers from loosening during the assembly process, so that the upper and lower end covers are always tightly on the annular filter element 2, thereby improving product quality.

[0019] like Figure 2 As shown, a connecting mechanism 5 is provided on the upper end cover 1, and the connecting mechanism 5 includes a connecting base 501 fixed in the upper end cover 1, a connecting guide rod 503 is fixedly installed in the middle position of the connecting base 501, a guiding front cone 506 is fixedly installed at the lower end of the connecting guide rod 503, a receiving groove 504 is provided at the lower end edge of the connecting guide rod 503, an elastic bayonet 505 is provided in the receiving groove 504, a connecting through hole 502 is provided at the edge of the connecting base 501, and a screw is provided in the connecting through hole 502, the connecting base 501 is fixed in the upper end cover 1 by screws, the connecting guide rod 503 is installed in the upper end cover 1 through the connecting base 501, and the elastic bayonet 505 is installed on the connecting guide rod 503 through the receiving groove 504.

[0020] Specifically, the connecting guide rod 503 can be installed in the upper end cover 1 through the connecting base 501. After pressing the elastic latch 505, it will shrink into the storage groove 504. During the assembly process, the guiding front cone 506 can guide the connecting guide rod 503 into the positioning pillar 603.

[0021] like Figure 3 As shown, the limiting mechanism 6 includes a positioning base 601 fixed on the lower end cover 3, a positioning pillar 603 is fixedly installed on the positioning base 601, a limiting slot 604 is provided at the upper edge of the positioning pillar 603, a spring 605 is provided in the positioning pillar 603, a limiting push plate 606 is provided above the spring 605 in the positioning pillar 603, a positioning through hole 602 is provided at the edge of the positioning base 601, and a screw is provided in the positioning through hole 602, the positioning base 601 is fixed in the lower end cover 3 by screws, the positioning pillar 603 is installed in the lower end cover 3 through the positioning base 601, one end of the spring 605 is connected to the limiting push plate 606, and the other end of the spring 605 is connected to the inside of the positioning pillar 603, and the elastic bayonet 505 is connected to the positioning pillar 603 through the limiting slot 604.
