Abstract

The invention discloses a 360-degree fan turbine device with the optimized pneumatic performance. The turbine device comprises a rotary shaft for connecting a turbine with a working motor, blades, a flat plate, a motor fixing rack and a base, wherein the turbine is covered by a netty outer cover; the blades are circumferentially mounted on the rotary shaft at an equal interval and directly connected with the flat plate; the turbine is connected with the motor through a rotary shaft; the motor is correspondingly fixed to the motor fixing rack; the motor fixing rack is fixed in the base. The turbine device is improved, namely a flow guide plate with the impact reduction performance, a toothed structure and a stepped structure are improved to improve the pneumatic performance of the 360-degree fan. The turbine device has the characteristics of efficient pneumatic performance, low noise and the like.

Description

technical field [0001] The invention belongs to the technical field of fans, in particular to a 360° fan with optimized aerodynamic performance. Background technique [0002] Traditional fans can only blow in one direction in the air outlet direction, such as axial fans. Traditional fans cannot guarantee that the wind will be delivered in all directions. Some fans on the market need to be swayed constantly so that there is wind in every direction, but it cannot satisfy the need for wind to blow through every moment. And in the ordinary appearance, in the competitive fan market, it does not have eye-catching features. [0003] In order to solve the above problems, 360° fans have been launched on the market. As the name suggests, the 360° fan can blow the wind in a 360° ring. It solves the problem of 360° no dead angle air outlet at every moment. The 360° fan not only has such excellent air performance, but also has a classical appearance. The fan combines classical and ...
