The flow guiding structure shown in fig. 1-5 includes a frame and a guide vane 2, where the guide vane 2 is installed on the frame, and when the flow guiding structure is applied to the circumferential outlet fan, the frame is a main structure of a casing of the circumferential outlet fan. The frame includes a plurality of support columns 1, and the air-out region can be formed between any two adjacent support columns 1.

Wherein, stator 2 rotates with two adjacent support columns 1 respectively through its both ends to be connected, arranges a plurality ofly between two adjacent support columns 1 stator 2, stator 2 sets up in every air-out region promptly. The guide vane 2 functions to make the outlet air flow according to a certain restriction.

When the guide vane 2 is rotated to a designated angle, the corresponding air outlet area can be completely or partially closed. When all the guide vanes 2 in a certain air outlet area rotate to the designated angle, the air outlet area is completely closed, and the states of the guide vanes 2 are shown in fig. 1-6; when only part of the guide vanes 2 in a certain air outlet area rotate to the specified angle, the air outlet area is partially sealed, namely, the part of the air outlet area covered by the guide vanes 2 rotating to the specified angle is sealed, and other parts of the air outlet area can still be used for air outlet.

When the guide vanes 2 do not rotate to the designated angle, an air outlet channel is defined between any two adjacent guide vanes 2, air flow can be blown out through the air outlet channel, when all the guide vanes 2 in a certain air outlet area do not rotate to the designated angle, the air outlet area is completely opened, and the guide vane state is as shown in fig. 10-14. The rotation of stator 2 can change the shape in air-out wind channel, and then can adjust the direction and the amount of wind of air-out.

When the flow guiding structure is applied to the circumferential outlet fan, preferably, each of the supporting columns 1 is parallel to the axial direction of the motor 3 of the circumferential outlet fan, that is, the direction of the rotation axis of the rotor of the motor 3 in the circumferential outlet fan, so that all the supporting columns 1 are arranged in parallel. The air inlet and outlet mode of the circumferential air outlet fan is axial air inlet, and 360-degree air outlet is performed in the direction perpendicular to the axial direction, so that an air outlet area can be formed between any two adjacent support columns 1. Wherein the stator 2 can be around perpendicular to the axial axis of rotation is rotatory, and the noise production of fan is mainly related to with stator 2 that the axial direction set up, compares with the stator that the axial direction set up, and the noise that the stator 2 produced that perpendicular to the axial setting in this embodiment is lower, and user experience feels better.

The water conservancy diversion structure of circumference air-out fan in above-mentioned embodiment has a plurality of air-out regions, and accessible stator 2 closes or opens every air-out region alone to through the rotation angle of stator 2 in adjustment every air-out region, can adjust the air-out angle in every air-out region freely, the regulation and control amount of wind can satisfy the different demands of blowing in a plurality of directions.

When support column 1 was provided with threely, will form three air-out region, when support column 1 was provided with four, will form four air-out regions, when support column 1 was provided with N, will form each air-out region of N, and it is the integer of more than or equal to 3 to show N.
