[0029] When it is necessary to detach the cover body 2 from the box body 1 for maintenance of the inside of the box body 1, first use the translation adjustment mechanism to drive the two sets of trapezoidal blocks 4 on the left and right sides of the box body 1 to move towards each other until they are completely separated from the two sets of triangular blocks 6, that is, the locking and fixing of the cover body 2 is released. At this time, the cover body 2 can be directly taken off from the top of the box body 1 to complete the disassembly, and the corresponding parts inside the box body 1 can be maintained and repaired. After the maintenance and repair are completed, the cover body 2 is covered on the top of the box body 1 again. Then use the translation adjustment mechanism to drive the two sets of trapezoidal blocks 4 on the left and right sides of the box body 1 to move in opposite directions until they contact and abut against the two sets of triangular blocks 6, that is, the locking and fixing of the cover body 2 is realized, and the convenient disassembly and assembly work is completed;

[0030] When it is necessary to remove the filter screen 8 on the cover body 2 for cleaning, first release the pressing and fixing of the frame body 7 by the pressing mechanism, then the frame body 7 together with the filter screen 8 inside it can be taken out from the inside of the cover body 2, and corresponding cleaning work can be carried out. After the cleaning is completed, the frame body 7 together with the filter screen 8 is inserted and fitted into the inside of the cover body 2, and the frame body 7 is pressed and fixed by the pressing mechanism, thus completing the convenient disassembly and assembly of the frame body 7 and the filter screen 8 inside it.
