The guide plate 5 is a strip-shaped structure which is transversely arranged, the guide plate 5 is fixed on the outer side of the upper part of the valve plate 2, and two side edges of the guide plate 5 in the length direction are adjacent to the corresponding side walls of the air valve shell 1. The valve plate 2 and the guide plate 5 rotate synchronously under the drive of the motor 3.

The air valve shell 1 is of a square structure, an air inlet 11 is formed in the bottom of the air valve shell 1, a first air outlet 12 is formed in the side portion of the air valve shell 1, and a second air outlet 13 is formed in the top of the air valve shell 1. As shown in fig. 1 and 2, when the valve plate 2 is driven by the motor 3 to rotate downward to a vertical position, the edge of the valve plate 2 abuts against the air valve housing 1, the first air outlet 12 is closed, and the second air outlet 13 is opened. As shown in fig. 3 and 4, when the valve plate 2 rotates upward to an inclined position, the edge of the valve plate 2 abuts against the inner wall of the air valve housing 1, the first air outlet 12 is opened, and the second air outlet 13 is closed.
