The wind scooper 133 of the embodiment can discharge all the air accelerated by the wind wheel 132 through the wind outlet 1334, so that the cooling effect of the fan 1 is improved, and the user experience is better.

Specifically, the rotating shaft of the wind wheel driving member 131 is perpendicular to the rotating shaft of the rotary driving member 12, so that the air outlet area of the fan 1 can be increased, and the plurality of fan blades 1322 are uniformly distributed on the circumference which takes the center of the connecting disc 1321 as the center of circle, so that the cooling effect of the fan 1 can be improved.

The embodiment of the present invention shows a fan 1, as shown in fig. 1-2, the wind wheel 132 rotates to generate wind for cooling and refreshing and ventilating air, and at the same time, the rotary driving member 12 drives the wind wheel 132 to rotate around the rotating shaft of the rotary driving member 12 by driving the wind wheel driving member 131. Because the rotary driving member 12 slowly drives the wind wheel 132 to rotate, a user feels that wind blows a gust when using the fan 1, thereby avoiding symptoms such as cold, headache, nasal obstruction and the like caused by long-time direct blowing, simultaneously ensuring the cooling effect and having better user experience.
