In this embodiment, the auxiliary air guide plate 320 is fixedly connected with the main air guide plate 310 through the air guide plate 330 , and the auxiliary air guide plate 320 rotates as the main air guide plate 310 rotates. By setting the size of the auxiliary air guide plate 320 to be smaller than the size of the main air guide plate 310 , the auxiliary air guide plate 320 can be prevented from interfering with the rotation of the main air guide plate 310 and the direction of wind guide.

In one embodiment, as shown in FIG. 6 to FIG. 8 , both ends of the air guide fins 330 are fixedly connected to the main air guide plate 310 and the secondary air guide plate 320 respectively, and in the air outlet direction, the plurality of air guide fins 330 are arranged in the shape of a Divergent distribution.
