A receiving groove 14 is provided at the top of the inner wall of the lifting port 10, and the other end of the spring 13 is fixedly connected to the top of the inner wall of the receiving groove 14. The receiving groove 14 is used in conjunction with the spring 13, and when the spring 13 is used in conjunction with the movable ring 7, a contraction receiving groove 14 can be provided for the spring 13, thereby avoiding the situation where the spring 13 is difficult to accommodate during the working contraction process, resulting in the movable ring 7 being difficult to move upward, thereby improving the convenience of contraction and accommodation of the spring 13.

[0034] Reference Figure 3In a preferred embodiment, by providing limiting openings 15 at the four corners of the top of the bottom plate 3, the limiting openings 15 are internally movably connected to limiting blocks 16, and the top of the limiting blocks 16 is fixedly connected to the bottom of the air filter body 1, so that when the bottom plate 3 is used in conjunction with the bottom plate 3, the bottom plate 3 and the air filter body 1 can be docked and limited, so as to avoid the situation that the air filter body 1 and the bottom plate 3 are difficult to align during the docking process, thereby improving the stability of the docking between the bottom plate 3 and the air filter body 1, and the limiting blocks 16 are provided with screw holes 17 inside, and the internal threads of the screw holes 17 are connected with screws 18, and the inner side of the screws 18 is threadedly connected to the bottom plate 3, so that when the limiting blocks 16 are used in conjunction with the bottom plate 3 and the air filter body 1, the bottom plate 3 and the air filter body 1 can be threadedly connected through the limiting blocks 16, so as to avoid the situation that the bottom plate 3 is difficult to install and connect when the air filter body 1 is used, thereby improving the convenience of installing and connecting the bottom plate 3 and the air filter body 1.

[0035] Reference Figure 3-Figure 4 In a preferred embodiment, a screw groove 19 is opened on the inner side of the inner wall of the limit opening 15, and the outer side of the screw 18 is located inside the screw groove 19. The screw groove 19 is used in conjunction with the screw 18.

[0036] Specifically, the working process or working principle of the air filter element structure is as follows: during use, when the filter element 2 needs to be disassembled, cleaned or replaced, the screw 18 is turned with the help of a screwdriver 18 to disengage from the screw groove 19 and enter the screw hole 17, and then the air filter body 1 is held by hand and moved upward to separate from the bottom plate 3. At this time, the limit block 16 follows the air filter body 1 to move upward to disengage from the limit port 15, and then according to the size of the garbage bag actually used, the outer rod 5 is moved toward the outer ring 4 to change the position between the outer rod 5 and the filter element 2. At this time, the moving seat 9 follows the outer rod 5 to move inside the moving groove 8 to perform mobile connection work between the outer rod 5 and the bottom plate 3. At the same time, the magnetic sheet 21 follows the moving seat 9 to move on the top of the magnetic strip 20, and the moving seat 9 performs magnetic attraction positioning work between the moved outer rod 5 and the bottom plate 3, and then, the garbage bag is held in hand. The outer rod 5 is sleeved on the outside of the filter element 2, and the movable ring 7 is pulled up by the lifting plate 11 and the connecting frame 12. At this time, the spring 13 is affected by the upward moving force of the lifting plate 11 and shrinks into the accommodating groove 14, preparing for the subsequent downward thrust on the movable ring 7, and then the garbage bag opening is placed in the movable groove 6, and then the lifting plate 11 is slowly released. At this time, the spring 13 applies a downward thrust to the movable ring 7 through the lifting plate 11 and the connecting frame 12, and the movable ring 7 clamps the garbage bag downward in the movable groove 6. Then, the filter element 2 can be separated from the outer ring 4 by flipping the bottom plate 3 by hand, and the filter element 2 can be disassembled. During this process, the dirt attached to the surface of the filter element 2 falls into the garbage bag sleeved on the surface of the outer rod 5, and the dirt attached to the surface of the filter element 2 is scattered, so that the user can disassemble, clean and replace the filter element 2.

[0037] It should be noted that the air filter body 1 and the filter element 2 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
