Detailed Description

In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clear, understand, combine the embodiment below, it is right the utility model discloses go on further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The first embodiment is as follows:

referring to fig. 1 and 2, an omnidirectional flow guiding body is a cone shape, and the outer circumferential surface of the cone shape is a flow guiding surface 1.

One side of the flow guide surface 1 close to the direction of the vertex of the cone is a flow inlet end 2.
