Abstract

The invention discloses a fan blade assembly of a cooling fan. The fan blade assembly comprises a hub, a connecting ring, reinforcing ribs, an inner fan blade, an outer fan blade, arc-shaped convex blocks and the like. According to the fan blade assembly, the inner fan blade is arranged on the inner side of the hub, and the outer fan blade is arranged on the outer side of the hub, so that wind power of a radiating area in the centers of the fan blades can be effectively increased, the wind amount and the wind speed of the whole cooling fan are increased, the softness of wind is increased, andthe cooling speed is increased; the reinforcing ribs are arranged between the hub and the connecting ring, so that the hub structure is stable, and deformation and cracking during rotation are avoided; a toothed structure is arranged on the second end surface of the outer fan blade, so that fluid pressure formed in the high-speed rotating process of the fan blades can be reduced, thereby reducingnoise; and the arc-shaped convex blocks are arranged around the bottom surface of the hub, so that the fan blade assembly is convenient to install.

Description

Technical field: [0001] The invention belongs to the technical field of fans, and in particular relates to a fan blade assembly of a cooling fan. Background technique: [0002] A fan is an electrical device that uses a motor to drive the blades to rotate to accelerate the flow of air. It is mainly used for heat dissipation and air circulation. Widely used in homes, offices, shopping malls and other places. [0003] At present, the fans on the market generally use single-layer fan blades. During the use of this kind of fan, the center of the fan blade cannot generate wind, so that the area radiated from the center of the fan blade has weak wind force, while the surrounding wind force is too strong, which makes people feel uncomfortable. . Invention content: [0004] Therefore, the technical problem to be solved by the present invention is that the fan blades used in the prior art for cooling fans adopt single-layer fan blades, and the wind force at the center is relativel...
