An air outlet 4 is opened on the side of the outer shell 1 away from the air inlet 3. An activated carbon plate 5 is arranged inside the outer shell 1. A flow guide seat 6 is distributed on one side of the activated carbon plate 5. A filter cotton stacking plate 7 is arranged on the other side of the flow guide seat 6. A honeycomb filter plate 8 is distributed on the side of the filter cotton stacking plate 7 away from the flow guide seat 6. An end cover 9 is distributed above the outer shell 1. A first spring 10 is fixedly connected to the inner side of the top end of the activated carbon plate 5. The other end of the first spring 10 is fixedly connected to a locking rod 11. An auxiliary sliding plate 12 is sleeved on the outer side of one end of the locking rod 11. A clamping structure is arranged on one side of the top end of the filter cotton stacking plate 7;

[0022] During use, first assemble multiple filter structures, and then install the end cap 9 and the outer housing 1 using the set bolts. Then, air enters the inside of the outer housing 1 through the air inlet 3, flows through the filter chamber 2, and then is filtered by the structures inside the outer housing 1 and discharged through the set air outlet 4.

[0023] As a further implementation of this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an activated carbon plate 5 is arranged inside the outer housing 1, and a flow guide seat 6 is distributed on one side of the activated carbon plate 5. A filter cotton stacking plate 7 is arranged on the other side of the flow guide seat 6, and a honeycomb filter plate 8 is distributed on the side of the filter cotton stacking plate 7 away from the flow guide seat 6. An end cap 9 is distributed above the outer housing 1. The inner top end of the activated carbon plate 5 is fixedly connected with a first spring 10, and the other end of the first spring 10 is fixedly connected with a locking rod 11. The locking rod 11 is slidably connected with the activated carbon plate 5 through the first spring 10, and the locking rods 11 are symmetrically distributed along the vertical center line of the activated carbon plate 5. An auxiliary sliding plate 12 is sleeved on the outer side of one end of the locking rod 11. A clamping block 13 is arranged on one side of the top end of the honeycomb filter plate 8, and a convex block 14 is fixedly installed at the bottom of the clamping block 13. The clamping blocks 13 are symmetrically distributed along the vertical center line of the filter cotton stacking plate 7, and the clamping blocks 13 and the filter cotton stacking plate 7 are integrally structured. A damper 15 is arranged on the side wall of the top end of the honeycomb filter plate 8, and the other end of the damper 15 is fixedly connected with a positioning rod 16. A second spring 17 is sleeved on the outer surface of the damper 15. The clamping block 13, the convex block 14, the damper 15, the positioning rod 16 and the second spring 17 form a clamping structure, and the clamping structure is arranged on one side of the top end of the filter cotton stacking plate 7. A slide rail 18 is arranged on the inner side wall of the outer housing 1, and a locking hole 19 is opened on one side of the top end of the slide rail 18. A secondary filter plate 20 is arranged in the inner cavity of the flow guide seat 6.

[0024] During assembly, first, the activated carbon plate 5 is input into the inner side of the outer housing 1, and its two sides slide along the slide rails 18. Then, when the activated carbon plate 5 is completely input into the inner side of the outer housing 1, the reverse force generated by the deformation of the first spring 10 will push the locking rod 11, thereby realizing the lateral movement of the locking rod 11. Subsequently, one end of the locking rod 11 will be input into the inner side of the locking hole 19, and thus the quick connection between the activated carbon plate 5 and the outer housing 1 can be achieved. Subsequently, the filter cotton stacking plate 7 is snapped into the inner side of the outer housing 1. At the same time, the clamping block 13 will be input into the inner side of the clamping table 21, and the convex block 14 provided at its bottom will be engaged in the hole opened at the bottom of the clamping table 21, thereby realizing the quick connection between the filter cotton stacking plate 7 and the outer housing 1. Finally, the honeycomb filter plate 8 is input into the inner side of the outer housing 1. Immediately, the reverse forces generated by the deformation of the damper 15 and the second spring 17 will laterally push the positioning rod 16, and then one end of the positioning rod 16 is input into the inner side of the positioning hole 22, thereby realizing the quick connection between the honeycomb filter plate 8 and the outer housing 1. When the filtration structure is assembled, the connection between the end cover 9 and the outer housing 1 is realized, and the closure of the entire filter can be achieved. When in use, when air enters the inner side of the filter chamber 2, it will be preliminarily filtered by the provided activated carbon plate 5. Then, the air passes through the flow guide seat 6 and is subjected to secondary filtration and purification through the secondary filter plate 20 provided inside the flow guide seat 6. Subsequently, combined with the provided filter cotton stacking plate 7 and the honeycomb filter plate 8, the air can be finally filtered and purified, and thus the impurities mixed in the air can be fully removed.
