Fan capable of supplying air from two sides simultaneously

Abstract

The fan comprises a fan body and a driving device, the fan body comprises an A-end hub, a B-end hub, a fan blade middle connecting section, an A-end fan blade group and a B-end fan blade group, one output end of the driving device is coaxially and fixedly connected with a first extending shaft, and the other output end of the driving device is coaxially and fixedly connected with a second extending shaft; one output end of the driving device is coaxially and fixedly connected with a first projecting shaft, the other end of the first projecting shaft is coaxially and fixedly connected with an A-end hub, the other output end of the driving device is coaxially and fixedly connected with a second projecting shaft, the other end of the second projecting shaft is coaxially and fixedly connected with a B-end hub, and an A-end fan blade group is fixed to the side wall, in the circumferential direction, of the A-end hub; a B-end fan blade group is fixed to the side wall of the B-end hub in the circumferential direction, and the A-end fan blade group and the B-end fan blade group are fixedly connected through a fan blade middle connecting section. The invention has the technical effects that double-sided air supply can be realized at the same time, the air supply distance and the air sweeping area are greatly improved under the same condition, and the utilization rate of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of axial flow fans, in particular to a fan capable of blowing air from both sides at the same time. Background technique [0002] Existing fans include axial fans, centrifugal fans, cross-flow fans, etc. Since the fan was invented, it has undergone considerable development and updating, and its structural type has basically been finalized. [0003] If the existing fans need to achieve long-distance air supply, large-scale adjustments to the shape of the fan blades are required, such as increasing the inclination angle of the fan blades, etc., resulting in the problem that the shape of the blades is not easy to process. Contents of the invention The object of the present invention is to provide a fan capable of blowing air from both sides at the same time, so as to solve the problems raised in the above-mentioned background technology. [0005] In order to achieve the above object, the invention provide...
