When the driving motor 5 drives the circulation fan 4 to rotate, the circulation fan 4 discharges the airflow in the circulation chamber 101 from the exhaust port 103 to the car 1.

[0017] In this embodiment, the circulation chamber 101 is equipped with an air-conditioning mechanism, which includes an evaporating stack 10.

When it is necessary to lower the temperature in the compartment 1, start the compressor 12 and the cooling fan 14, and the refrigerant in the refrigerant tank 15 is vaporized at the evaporating stack 10 to refrigerate the circulating airflow. The vaporized refrigerant is compressed by the compressor 12 and transported to the condensing stack 13 to liquefy and dissipate heat again; when it is necessary to increase the temperature in the compartment 1, start the heating wire 16 to heat the circulating airflow; when it is necessary to disinfect the entire compartment 1, open the sliding cover 7 and evacuate the personnel to the outside of the compartment 1; the internal circulation disinfection system of the utility model can circulate, filter and disinfect the air in the compartment 1, and the structure of the embedded ventilation box 2 is convenient for cleaning and maintenance of the ultraviolet lamp 3.
