[0042] Working principle: When in use, wind is input into the elevator car body 1 through the ventilation component, and the air enters the elevator car body 1 from the outside of the first box body 2. After the air enters the first box body 2, the dust-proof cotton 9 can filter the dust and impurities in the air to prevent the dust and impurities from entering the elevator car body 1. The wind force entering the first box body 2 can be detected by the detection component. If the wind force becomes smaller, it means that a large amount of dust and impurities are attached to the dust-proof cotton 9 to block the air from entering. The new dust-proof cotton 9 can be replaced by the replacement component to continue working. Before entering the elevator car body 1, the air will pass through the cylinder 25. The cotton ball in the cylinder 25 contains a deodorant and freshener. The air can bring the deodorant and freshener factor into the elevator car body 1, making the incoming air fresher. The deodorant and freshener can be added to the cotton ball by adding a component;

[0043] When the elevator car body 1 needs to be ventilated, the first motor 3 is started, and the first motor 3 drives the first blade 4 to rotate. The rotation of the first blade 4 can inhale air from the outside of the first box body 2, and the air passes through the mesh 8 and the dust-proof cotton 9 in turn. The mesh 8 can prevent larger garbage from entering the first box body 2, and the dust-proof cotton 9 can filter dust and impurities. The air passes through the opening 5 to the air outlet box 6, and finally the air is evenly discharged from each air outlet 7 into the elevator car body 1;

[0044] After the air enters the first box body 2, it passes through the V-shaped section 901, the first inclined section 902, the second inclined section 903 and the vertical section 904 in sequence. The multi-layer dustproof cotton 9 can filter dust and impurities multiple times, and achieve a better filtering effect. By providing the V-shaped section 901, the first inclined section 902 and the second inclined section 903, the contact area between the air and the dustproof cotton 9 can be increased;

[0045] When a large amount of dust and impurities adhere to the dustproof cotton 9 and the dustproof cotton 9 needs to be replaced, the second motor 12 is started, and the second motor 12 drives one of the first rotating shafts 11 to rotate, and the first rotating shaft 11 drives the other first rotating shaft 11 to rotate through the sprocket 13 and the chain 14. The two first rotating shafts 11 rotate to put new dustproof cotton 9 into the first box body 2, and roll up the old dustproof cotton 9 onto its surface, and the dustproof cotton 9 moves around the rotating roller 15;

[0047] When the air enters the first box body 2, the air will pass through the wind receiving plate 42 and will blow the wind receiving plate 42 to rotate around the fifth rotating shaft 40, the round block 41 at the top of the wind receiving plate 42 will rotate, the round block 41 drives the spur rack 44 to move through the arc-shaped rack 43, the spur rack 44 drives the connecting plate 45 to move, the spring 46 is stretched, and the movement of the spur rack 44 can make the induction block 47 on it contact with another induction block 47. When there is a lot of dust and impurities attached to the V-shaped segment 901, the air volume reaching the wind receiving plate 42 will decrease, and the wind force received by the wind receiving plate 42 will decrease. Under the action of the spring 46, the spur rack 44 drives the wind receiving plate 42 to rotate back through the arc-shaped rack 43. The movement of the spur rack 44 can separate the two induction blocks 47. At this time, the second motor 12 can be started to replace the dustproof cotton 9. After the replacement is completed, the air volume reaching the wind receiving plate 42 increases, and the two induction blocks 47 contact each other.

[0048] When the first motor 3 is started to deliver air into the elevator car body 1, the air passing through the opening 5 drives the second blade 27 to rotate, and the second blade 27 rotates through the stirring rod 28 at the top of the fourth rotating shaft 26. The stirring rod 28 can stir the cotton balls in the cylinder 25 to form gaps between the cotton balls, so that air can fully flow through the gaps between the cotton balls, and the air will fully carry the deodorant and freshener factor after passing through;

[0049] When the second motor 12 is driven to replace the dust-proof cotton 9, the rotation of the first rotating shaft 11 can drive the rotating plate 36 to rotate, and the rotation of the rotating plate 36 can drive the connecting rod 35 to move upward, and the connecting rod 35 drives the connecting tube 33 to move upward. The connecting rope 37 is stretched, so that the connecting tube 33 slides in the annular groove 32, so that the opening 34 is higher than the top of the hollow base 31, and the deodorant freshener in the storage box 29 will pass through the opening 34, the hollow base 31, and the connecting tube 30 in sequence to reach the cotton balls in the cylinder 25, thereby achieving the purpose of adding deodorant freshener to the cotton balls. When the rotating plate 36 passes the connecting rod 35, under the action of the connecting rope 37, the connecting tube 33 moves downward, so that the opening 34 enters the annular groove 32, and the adding channel is closed.
