[0028] The dismounting assembly includes fixed rod 11, and the fixed rod 11 is fixedly connected in both sides inside the air inlet 4, the moving block 12 is slidably connected outside the two fixed rods 11, the horizontal rod 14 is fixedly connected on the moving block 12, and the horizontal rod 14 is set up to facilitate the use of operator, the reset spring 13 is fixedly connected with left side outside the moving block 12, the plug block 15 is fixedly connected with right side outside the moving block 12, the first through hole 7 is set up in the air inlet 4, and the first through hole 7 is connected with the assembly installation cavity of air inlet 4, and the horizontal rod 14 is slidably connected in the first through hole 7, and the first through hole 7 is set up to facilitate the movement of horizontal rod 14, the insertion hole 10 is set up in both sides outside the air inlet 4, and the two protruding blocks 8 are inserted with the two insertion holes 10, and the preliminary fixation of cover body 6 is achieved, the second through hole 16 is set up in the air inlet 4, and the plug block 15 is slidably connected in the second through hole 16, and the second through hole 16 is set up to facilitate the movement of plug block 15, the clamping groove 9 is set up in the protruding block 8, and the plug block 15 is inserted with the clamping groove 9, and the fixation of cover body 6 is achieved.

[0029] Specifically, when disassembling the cover body 6, first, the operator needs to move the cross rod 14, which carries the lower fixed moving block 12 to slide outside the two fixed rods 11. When the moving block 12 starts to move, it will move the right side fixed plug block 15 together. The plug block 15 interacts with the left side reset spring 13, which is extruded and deformed during this process, thereby storing a certain amount of energy. When the plug block 15 completely leaves the inside of the clamping groove 9, the cover body 6 and the protrusion 8 can be easily removed from the outside of the air inlet 4. This completes the disassembly of the cover body 6. This process is very simple, and the operator does not need to use any tools such as loosening or tightening the bolt 24, thus saving a lot of time and labor intensity. When installing the cover body 6, the operator only needs to insert the protrusion 8 fixed outside the cover body 6 into the inside of the two insertion holes 10 and ensure its position. Then, loosen the cross rod 14. Under the action of the reset spring 13, the plug block 15 will automatically insert into the inside of the clamping groove 9, completing the entire installation process.

During the entire process, the operator does not need to perform tedious bolt 24 operations. Only by simply inserting and loosening the cross rod 14, the operator can easily complete the installation and disassembly. In this way, not only the time and energy required for operation are reduced, but also the labor intensity of the operator is greatly reduced.

[0030] Referring to Figure 2 and Figure 3 The filter assembly includes a fixed plate 17 provided outside the box body 1. The fixed plate 17 is fixedly connected with extension blocks 23 on both sides outside. The two extension blocks 23 are threadedly connected with bolts 24 inside. The fixed plate 17 is fixedly connected with a coarse filter screen 19 on the outside rear side. The coarse filter screen 19 can intercept larger particles of dust. The coarse filter screen 19 is installed with a fine filter screen 20 outside. The fine filter screen 20 can remove smaller particulate matters in the air. The fine filter screen 20 is installed with adsorbing cotton 21 outside. The adsorbing cotton 21 can capture harmful gases in the air, such as formaldehyde, benzene, ammonia, sulfur dioxide, etc., to reduce the content of toxic substances in waste gas. The adsorbing cotton 21 is installed with an activated carbon plate 22 outside. The activated carbon plate 22 can effectively adsorb and remove VOCs, reducing their potential harm to health. The fixed plate 17 is fixedly connected with a handle 18 outside. The handle 18 is provided for the convenience of the operator. The box body 1 is provided with a positioning hole 25 on the outside front side. The bolt 24 is threadedly connected inside the positioning hole 25. The bolt 24 is provided for the convenience of fixing the fixed plate 17.
