Abstract

This utility model discloses a disinfection and purification air duct, which is installed at the corner of the roof of a vehicle and connected to the vehicle's air conditioning system. The disinfection and purification air duct includes a top profile, a bottom profile, and a door body. The top and bottom profiles are fixedly connected to the vehicle body. The upper and lower ends of the door body are connected to the top and bottom profiles, respectively, forming the air duct. Air outlets are spaced apart on the bottom profile, and each air outlet is equipped with an air outlet cover. A set of connecting clips is provided inside the air outlet cover for connecting the air outlet cover to the bottom profile. A set of fixing clips is also provided on the air outlet cover, located inside the connecting clips, for fixing the disinfection component. The disinfection component is connected to and controlled by the vehicle's computer. This design improves the air outlets and adds a disinfection component to ensure healthy airflow from the air conditioning system. Furthermore, the profile design allows for the modification of existing buses at a low cost.
