The hot air enters an independent space connected to the air inlet 72. The hot air ejected from the air inlet 72 will drive the impeller 75 and the blades 76 to rotate, and the independent space filled with hot air will also rotate accordingly. Since the gap between the blades 76 and the shell 71 is extremely small, when the independent space does not reach the air outlet 73, the hot air can only circulate in the independent space. In the process from the air inlet 72 to the air outlet 73, the ultraviolet lamp 77 located on the blade 76 continuously sterilizes and disinfects the hot air. After the independent space reaches the air outlet 73, the hot air in the independent space enters the room through the air outlet 73 and the air outlet 8 on the body 1.
