Problems solved by technology
[0002] In the prior art, the hub of the fan blade is generally designed as a regular cylindrical structure. However, such a design generally has the problems of high cost and power consumption, and the obvious peak noise, which reduces the working efficiency of the fan blade.
[0003] In order to solve these problems, there are also designs in the prior art that reduce noise by changing the structure of the fan blades, reduce the local area of work and thereby reduce the power consumption of the fan blades, but these solutions are all aimed at improving the shape of the fan blades, and the reduction of noise and The effect of power consumption is also weak

Embodiment Construction
[0023] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0024] Such as figure 1 with figure 2 As shown, the fan blade according to the present invention includes a hub 10 and a plurality of blades 20, the hub 10 is a cylindrical shape with a top seal, and the roots of the plurality of blades 20 are evenly arranged on the outer peripheral surface of the hub 10; the outer circumference of the bottom end of the hub 10 There are multiple notches on the surface equal to the number of blades 20 , wherein the outer peripheral surface between two adjacent notches is a triangular curved surface 30 . The present invention reduces the area of the hub 10 by setting a plurality of gaps corresponding to the number of blades 20 on the outer peripheral surface of the bottom end of the hub 10, and making the outer peripheral surface between two adjacent gaps form a triangular curved surface 30, thereby reducing the area of ...

The invention provides a fan blade as well as a fan system and an air conditioner system. The fan blade comprises a hub and a plurality of blades, wherein the hub is in a cylindrical shape with a closed top end, and root parts of the plurality of blades are uniformly arranged on the outer circumferential surface of the hub; a plurality of notches with the quantity being identical to that of the plurality of blades are formed on the outer circumferential surface of the bottom end of the hub, and the outer circumferential surface between every two adjacent notches is of a triangular curved surface. According to the fan blade as well as the fan system and the air conditioner system, a plurality of notches with the quantity being identical to that of the blades are formed on the outer circumferential surface of the bottom end of the hub, and the outer circumferential surface between every two adjacent notches is of the triangular curved surface, so that the area of the hub is reduced, the overall weight of the fan blade is reduced, and the production cost and power consumption are reduced; in addition, by adopting the triangular curved surface, the airflow separation phenomenon of a local position caused by a large twisted angle of each blade root can be effectively solved, the noise sound quality can be improved, and the overall performance of the fan blade can be improved.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to a fan blade, a fan system, and an air conditioning system. Background technique [0002] In the prior art, the hub of the fan blade is generally designed as a regular cylindrical structure. However, such a design generally has the problems of high cost and power consumption, and the obvious peak noise, which reduces the working efficiency of the fan blade. . [0003] In order to solve these problems, there are also designs in the prior art that reduce noise by changing the structure of the fan blades, reduce the local area of work and thereby reduce the power consumption of the fan blades, but these solutions are all aimed at improving the shape of the fan blades, and the reduction of noise and The effect of power consumption is also weaker. Contents of the invention [0004] The invention aims to provide a fan blade, a fan system and an air conditioning system with reduced ...
