A sealing plate 44 is threaded onto the screw 34, and a rubber pad 43 is fixed to the upper end of the sealing plate 44. The rubber pad 43 abuts against the lower end of the activated carbon filter 32. The operator can place the activated carbon filter 32 into the machine body 31, so that the activated carbon filter 32 abuts against the sleeve 42, and insert the base plate 36 into the third opening 30. Pushing the L-shaped rod 46 compresses the second spring 49. After the L-shaped rod 46 is aligned, it is released, and the second spring 49 pushes the L-shaped rod 46 back to its original position, so that the base plate 36 and the machine body 31 are connected as one unit. At this time, the turntable 35 can be rotated to rotate the screw 34, which causes the sealing plate 44 to drive the rubber pad 43 to rise and fall. This can effectively push the activated carbon filter 32 to rise and fall, and the activated carbon filter 32 can abut against the sleeve 42, thus effectively sealing it.

[0027] In this embodiment, the extrusion mechanism includes two slide rods 40 fixed on both sides of the lower end of the mounting plate 27. A first spring 38 is sleeved on the slide rod 40. The two ends of the first spring 38 are respectively fixed on the opposite side of the mounting plate 27 and the collar 37. A sealing ring 39 is fixed on the circumferential side wall of the collar 37. The sealing ring 39 abuts against the circumferential side wall inside the machine body 31. The sealing effect can be improved by the sealing ring 39.

[0028] In this embodiment, the base plate 36 is provided with two fifth openings 48. A sealing plate 44 is slidably installed and passes through the fifth opening 48. A second spring 49 is fixed on one side wall of the fifth opening 48. The second spring 49 is fixed to one end of the L-shaped rod 46. A sliding sleeve 47 is slidably sleeved on the L-shaped rod 46. The sliding sleeve 47 is fixed to the upper end of the base plate 36. One end of the L-shaped rod 46 passes through the body 31. A vertical rod 45 is fixed to the upper end of the L-shaped rod 46.

[0029] In this embodiment, an exhaust fan 26 is detachably connected to the mounting plate 27, and an air outlet 49 is provided through the upper end of the body 31. A grid plate 28 is installed inside the air outlet 49, and the exhaust fan 26 and the air outlet 49 correspond to each other.

[0030] In this embodiment, air inlets 33 are provided on both sides of the lower end of the body 31, and a first filter screen 29 is installed inside the air inlet 33.

[0031] In this utility model, the connector 4 and the building wall 1 are firmly connected by the expansion bolt 9. At the same time, the partition 8 is moved, which causes the partition 8 to drive the rack 18 to move. This causes the gear 19 to drive the rotating shaft 16 to rotate. The rotating shaft 16 drives the positive and negative thread screws 7 to rotate through the transmission belt 13. This causes the two threaded sleeves 6 to move to both ends, so that the insertion rod 3 moves into the insertion plate 5. The insertion plate 5 is aligned with the connector 4 and inserted. The partition 8 is released, and the reset spring 23 pushes the partition 8 to reset. The slider 20 can ensure the smooth movement of the partition 8, so that the insertion rod 3 can be inserted into the first opening 11, and the gas sterilization component 2 and the connector 4 can be firmly connected. The exhaust fan 26 operates, drawing air through the activated carbon filter 32 and the first filter screen 29. After entering the body 31, the gas can only pass through the activated carbon filter 32 and enter the fourth opening 41 into the exhaust fan 26. It can be discharged through the air outlet 25 and connected to the gas disinfection component 2 so that it can move in the direction of the exhaust fan component 24 under the action of the exhaust fan component 24, and can perform gas disinfection operation under the action of the gas disinfection component 2. The gas disinfection component 2 uses existing gas disinfection ventilators, such as the NARVA brand sterilizing electrostatic plasma air disinfection machine; it can draw in the gas in the medical building and disinfect the gas in the gas disinfection component 2 to improve air quality, while the exhaust fan component 24 can make the air exhaust from the top.
