Unscrew the screw-connected head 24, inject disinfectant or air purifier through the injection port 23, and tighten the head 24. After the damper 2 is opened, the pump body 21 pumps the liquid into the liquid collecting tank 20, sprays it out through the atomizing nozzle 22, and diffuses it into the room with the airflow. The connecting frame 4 can be provided with two sets of liquid storage tanks 19 and pump bodies 21, and the disinfection or purification function can be selected according to the direction of the airflow. Pull out the lifting rope 33 from the storage tank 31, untie the magnet block 35 adsorption, and bolt the rope to the indoor lifting ring. The four sets of lifting ropes 33 work together to share the weight of the damper 2 and the ventilation pipe 3, reducing the pipeline stress.
