Clamping components 6 are arranged inside the two cavities 5. Limiting components 7 are arranged on the left and right sides of the top of the frame 102, and are respectively located on the left and right sides of the tops of the two activated carbon filters 103. The tops of the two activated carbon filters 103 can be covered by two limiting components 7, and the two activated carbon filters 103 can be fixed inside the frame 102 by two clamping components 6 inside the two fixed blocks 4. In order to fix the blocking block 701 to the frame 102, the left clamping component 6 includes two clamping blocks 601, two moving blocks 602, a movable block 603 and a plurality of return springs 604. The surfaces of the two moving blocks 602 and the movable block 603 can be movably connected to the inside of the left cavity 5. The tops of the right sides of the two clamping blocks 601 are fixedly connected to the left sides of the two moving blocks 602, and the bottoms of the front and rear sides of the movable block 603 are respectively fixedly connected to the opposite ends of the two moving blocks 602.

[0027] The working principle of this utility model:

[0028] When the activated carbon filter 103 needs to be replaced, first remove the bolts fixing the two sockets 201 and the two plug-in blocks 202. At this time, the connecting plate 203 can drive the two plug-in blocks 202 to move upward and disengage from the pull block 101, so that the pull block 101 can be pulled forward to make the pull block 101 drive the frame 102 to move out from the inside of the shell 3. The movable block 603 is pulled upward by manpower to make the movable block 603 drive the two movable blocks 602 and the two clamping blocks 601 to move upward to make the two clamping blocks 601 move out from the inside of the frame 102. At this time, the baffle can drive the two limit blocks 702 to move to the left, so that the baffle and the two activated carbon filters are in contact. The activated carbon filter 103 is disengaged from the contact with the device 103, so that the activated carbon filter 103 that needs to be replaced can be removed, and the multiple handles 8 are pulled to drive the activated carbon filter 103 to move upward, so that the activated carbon filter 103 is moved out from the inside of the frame 102. When the activated carbon filter 103 needs to be fixed, the activated carbon filter 103 is plugged and connected to the frame 102, and the blocking block 701 blocks the activated carbon filter 103. The movement of the two moving blocks 602 will cause the multiple reset springs 604 to deform. After the movable block 603 is released, the elastic action of the multiple reset springs 604 causes the two moving blocks 602 to drive the two positioning blocks to rebound to their original positions, thereby fixing the activated carbon filter 103.
