[0027] Reference Figure 3 and Figure 4 The interior of the adsorption column 4 is provided with a sliding hole 5, and an activated carbon plate 6 is slidably connected to the interior of the sliding hole 5. These holes are used to support and accommodate the activated carbon plate 6. The front end of the activated carbon plate 6 is fixedly connected with a connecting block 7. This is used to facilitate the removal of the activated carbon plate 6. The outer rear side of the connecting block 7 is slidably connected to the front side of the adsorption column 4. The front side of the connecting block 7 is provided with a pulling hole 8 for operating the position of the connecting block 7. The interior of the connecting block 7 is provided with a movable hole 9 to provide additional movement space. The inner wall of the bottom end of the movable hole 9 is slidably connected to two sliding columns 10 for connecting force. A plurality of strong springs 11 are arranged inside the movable hole 9 to provide spring force and supporting force. Two strong springs 11 are respectively sleeved on the outside of the two sliding columns 10. This design is to ensure the stability of the two strong springs 11 when moving. One end of the strong spring 11 is fixedly connected to one side of the limit plate 12. The other end of the strong spring 11 is fixedly connected to one side of the inner part of the movable hole 9, and the top ends of the two sliding columns 10 are fixedly connected to a limiting plate 12 for limiting the position of the subsequent locking block 13. The limiting plate 12 is slidably connected to the inner part of the movable hole 9. This design provides stability. The top of the limiting plate 12 is fixedly connected to two locking blocks 13, and the outside of the locking block 13 is slidably connected to the top inner wall of the connecting block 7. The bottom ends of the two sliding columns 10 are fixedly connected to a pulling rod 14. The pulling rod 14 provides driving force, which is convenient for the staff to pull by hand. The left and right sides of the pulling rod 14 are respectively slidably connected to the left and right sides of the inner part of the pulling hole 8. Two locking holes 15 are provided on the front side of the adsorption column 4, and the outside of the locking block 13 is locked in the inside of the locking hole 15. This design provides fixation of the connecting block 7 and limits the connecting block 7, which will keep the activated carbon plate 6 stable inside the sliding hole 5.

[0028] Reference Figure 2 , Figure 5 and Figure 6 A filter plate 16 is fixedly connected to the top of the box body 1 for filtering air or other substances, and a fan 17 is fixedly connected to the inner bottom end of the filter plate 16 for circulating air, promoting air flow and improving filtering efficiency. An air inlet 18 is fixedly connected to the inner bottom end of the filter plate 16 for introducing air or gas to be treated, and a transmission pipe 19 is fixedly connected to the right end of the left adsorption column 4 for transporting the treated gas to a designated position. The right end of the transmission pipe 19 is fixedly connected to the left top end of the right adsorption column 4 to ensure smooth transmission of the gas. The outside of the air inlet 18 is fixedly connected to the left inside of the top of the box body 1 to facilitate the introduction of air or gas while maintaining the compactness of the system structure.

[0029] Working principle: First, start the fan 17. The movement of the fan 17 drives the gas to be filtered by the filter plate 16 and then flow through the air inlet 18 into the interior of an adsorption column 4. Then, start the vacuum pump 20. The movement of the vacuum pump 20 and the fan 17 causes the gas to flow. After passing through an activated carbon plate 6, the carbon dioxide in the gas is adsorbed by the activated carbon plate 6. Then, the gas is introduced into the interior of another adsorption column 4 through the transmission pipe 19. Then, the gas passes through the interior of another activated carbon plate 6 for secondary adsorption, thereby improving the capture efficiency of carbon dioxide. Then, the gas adsorbed is discharged through the air outlet 21 under the action of the vacuum pump 20. Then, the gas is discharged through the activated carbon plate 6. When replacing, first put your hand into the pulling hole 8, and then use your index finger and middle finger to pull the pulling rod 14, so that the pulling rod 14 drives the sliding column 10 to move, and then the movement of the sliding column 10 drives the limiting plate 12 to slide inside the movable hole 9, and then the sliding of the limiting plate 12 drives the locking block 13 and the locking hole 15 to separate, so that the connecting block 7 is no longer limited, and then pull the connecting block 7 to drive the activated carbon plate 6 to be taken out and replaced. The movement of the limiting plate 12 also drives the strong spring 11 to contract, and then the contraction of the strong spring 11 will generate a rebound force, which provides the force for the subsequent locking block 13 to engage with the locking hole 15.
