[0027] Space is left between two mounting boxes 14, and the size of mounting block 6 can just pass between two mounting boxes 14;

[0028] The lower end of the fixed rod 16 is bevel-shaped, when the mounting block 6 rotates on the air filter component 1, the mounting block 6 first contacts the bevel, and the fixed rod 16 can be pressed and lifted along the bevel, and the fixed rod 16 is simultaneously stretched by the first mounting plate and the first spring 17, when the mounting block 6 rotates to the position, the fixed hole 7 on the mounting block 6 is aligned with the fixed rod 16, the first spring 17 is retracted, the fixed rod 16 is moved by the first mounting plate, and the fixed rod 16 is inserted into the fixed hole 7 to fix the mounting block 6;

[0029] The limiting mechanism is installed on the mounting box 14, and the fixed rod 16 cannot completely separate from the mounting box 14 during movement;

[0030] The air filter component 1 is a component installed on an air filter in actual use, and the drawings are mainly used to show the structural principle.

[0031] As shown in Figures 1-8 The inner sides of the two mounting blocks 6 are abutted with the connecting plates 19, the two connecting plates 19 are fixedly connected to the inner side of the mounting sleeve 13, the inner sides of the two connecting plates 19 are movably sleeved with the transmission rods 20, the two transmission rods 20 are abutted with the adjacent mounting blocks 6, one side of each of the two transmission rods 20 is fixedly connected with the extrusion plate 22, and the inner sides of the two extrusion plates 22 are fixedly connected with the second springs 21. The inner sides of the two second springs 21 are respectively fixedly connected to one side of the two connecting plates 19. By adopting the above technical scheme, the extrusion plate 22 can extrude the air bag 23;

[0032] The length of the transmission rod 20 is designed to just push the extrusion plate 22 to extrude the air bag 23 during movement, and does not interfere with the inner wall of the mounting sleeve 13;

[0033] The limiting mechanism is installed on the connecting plate 19, and the transmission rod 20 cannot separate from the connecting plate 19 during movement.

[0034] As shown in Figures 1-8 The inner side of the mounting sleeve 13 is equidistantly fixedly connected with two air bags 23, and the two air bags 23 are arranged on one side of the two extrusion plates 22, respectively. The outer sides of the air outlet holes of the two air bags 23 are fixedly connected with the whistles 24. Through such a setting, the material of the air bag 23 is a wear-resistant material with a certain elasticity, which can restore the shape by its own elastic deformation after being extruded and deformed by the extrusion plate 22, and can be extruded and blown again.

[0035] As shown in Figures 1-7As shown, the outer side of the air filter component 1 is fixedly connected with a limiting shell 3, the limiting shell 3 is movably installed with a limiting ring 11, the inner side of the limiting ring 11 is fixedly sleeved with a movable sleeve 9, and the movable sleeve 9 is movably sleeved on the outer side of the mounting sleeve 13.
