[0025] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that it is easy for a person skilled in the art to implement these embodiments. However, the present invention may be implemented in various forms, and therefore the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, parts that are not connected to the present invention will be omitted from the accompanying drawings.

[0026] like Figure 1-2 As shown, a vent device includes: a housing 1, a fan blade 2, a support seat 3, a support rod 4, a screw rod 5, a screw sleeve 6, a motor 7, a fixed rod 8, and a movable rod 9;

[0027] The housing 1 is a hollow cylindrical structure with a protrusion on one end wall, the end with the protrusion is an air outlet, and the other end is an air inlet;

[0028] like Figure 3As shown, the number of the fan blades 2 is four, each of the fan blades 2 is a circular arc-shaped fan-shaped blade, and the sides of the two fan blades 2 are connected to form an overall tubular structure;

[0029] The bottom end of the fan blade 2 is movably arranged on the support seat 3;

[0030] The support seat 3 is a hollow hemispherical structure;

[0031] The support rod 4 is in a cross shape, and the four ends of the cross respectively penetrate the wall of the support seat 3 from the hemispherical support seat 3 and extend to the inner wall of the shell 1 to fasten the support seat 3. The center point of the cross-shaped surface of the support rod 4 passes through the diameter of the hemispherical body and the surface is perpendicular to the diameter of the hemispherical body.
