[0025] When using this device, the fan 1 sends air into the air guide bin 3 through the connecting pipe 2, and then the air flow in the air guide bin 3 is sent out through the right port of the air guide bin 3. The closed guide plate 4-1 cooperates with the side plate of the air guide bin 3 to form a filling channel to guide the air flow in the air guide bin 3 downward, and the air flow in the air guide bin 3 is guided and sent out from the right port of the air guide bin 3 through the opened guide plate 4-1.

The guide plate 4-1 is supported and rotated by the bearing shaft thereon, and the support shaft 4-2 drives the guide sleeve 9 to slide on the guide rod 7 through the support arm 8, and the guide sleeve 9 presses the support spring 10. After the guide plate 4-1 is rotated and opened, its upper side slides into the leak-proof frame 14, and the upper side of the guide plate 4-1 is pressed against the side wall of the leak-proof frame 14, so that the airflow in the air guide chamber 3 flows from top to bottom, and after passing through the opened guide plate 4-1, the airflow is guided by the opened guide plate 4-1 and discharged to the right.
[0026] Compared with the prior art, the present invention has the following beneficial effects: 1. This device is provided with an air guide chamber 3 with several guide plates 4-1. The fan 1 supplies air into the air guide chamber 3 through the connecting pipe 2. The closed guide plates 4-1 cooperate with the air guide chamber 3 to guide the air flow downward.
