At this time, the several plate holes 12 of the wind shield plate 5 and the several air supply ports 9 in the air supply space 7 are respectively connected one by one, and the wind shield plate 5 blocks the several exhaust ports 10 in the exhaust space 8; then the first air pump starts working, and under the drive of the first air pump, the clean air outside the garbage bin is sent to the vicinity of the garbage bin maintenance platform 19 through the air supply box 27, ensuring that the supplementary clean air covers the entire operating area of ​​the maintenance personnel, thereby greatly reducing the CO toxic and harmful gas content at the garbage bin maintenance platform 19, improving the working environment, and ensuring the safety of the maintenance personnel.

[0068] Taking into account that there is a certain distance between the maintenance platform 19 and the ventilation duct 1, in order to provide more sufficient clean air to the operators on the maintenance platform, the extension pipe 3 can be pulled out of the sliding groove by an appropriate distance, and the clean air can also be transported from the air supply hole 23 to the vicinity of the maintenance platform 19 of the garbage bin, closer to the operator.

[0069] If the operator still feels that the clean air supply is insufficient and he or she feels unwell, the elastic air supply hood 25 can be removed from the bracket 26. The elastic air supply hood 25 can be placed close to the outside of the operator's mouth and nose. In this way, the operator can inhale clean air without inhaling other gases in the garbage bin, which completely solves the potential safety hazard of the operator when operating in the garbage bin.
