Shutter type omnidirectional fan

The utility model relates to a fan, in particular to a shutter type omnidirectional fan, which comprises a rotary shaft and fan blades, and is characterized in that a wind tube (1), which is shaped like a container, is arranged outside the rotary shaft (4) and the fan blades (5), the wall of the wind tube (1) consists of a plurality of wind deflectors (2) and a frame (3), each wind deflector (2) makes an included angle with a straight line passing through the tube center, an wind gap (6) is arranged between each two wind deflectors (2), and thereby a shutter type structure is formed. Since the shutter type wind tube is adopted, most of the wind in any direction can be guided by the wind deflectors to form effective wind power opposite to the concave surfaces of the fan blades, consequently, the utility model resolves the problem that the wind powers at both sides of the rotary shaft of the radial flow type fan counteract each other, and thereby the utilization rate of wind power is notably increased.
