[0052] When the activated carbon needs to be replaced, the upper two baffle plates 22 are inserted into the box body 10 along the third through-hole 20. The baffle plates 22 move along the L-shaped card slot 21. The telescopic block 23 presses the baffle plates 22 and the first sealing ring 24 firmly on the support frame 14 and is located at the first through-hole 15. The second sealing ring 26 on the first limiting plate 25 fits at the third through-hole 20. At this time, the drawer 16 corresponding to the baffle plate 22 at this place can be pulled out;
