The atomizer box 501 and the dust collector 601 are turned on by the controller body 201 during the cleaning process, the atomizer box 501 stores disinfectant, the atomizer box 501 can atomize the disinfectant and deliver it to the fixed shell 503 through the conveying pipe 502, the fixed shell 503 is a hollow shell, the atomized disinfectant can be sprayed through the spray nozzle 504 for disinfection, the dust collector 601 can collect dust through the dust collection pipe 602 and the dust collection nozzle 603, and the dust and the used disinfectant can be collected and treated uniformly, which further improves the cleaning effect and the cleaning efficiency. The device can disinfect and sterilize and collect dust simultaneously during the cleaning process, which is time-saving and labor-saving.

[0044] In the existing technology, the cleaning process of the subway air conditioner is more complex and requires higher than that of the household air conditioner, the manual cleaning takes a long time, which greatly wastes subway resources and affects the normal operation of the subway company. The cleaning of the air conditioner pipeline in the subway is a difficulty, the air conditioner pipeline is full of a large amount of dust and respiratory disease bacteria, which greatly endangers the safety of passengers during the subway operation.
