[0004] The above-mentioned fan has only a simple motor and fan blade structure. When in use, the wind force is not concentrated and the wind force is small. The actual use effect is not good and needs to be improved. Summary of the invention

[0005] In order to improve the problem that the wind force of the fan is not concentrated, the wind force is small, and the actual use effect is poor when the fan is used, the present application provides a carbon fiber quality controlled light rotation fan.

[0007] By adopting the above-mentioned technical scheme, the arc-shaped wind-blocking block can be installed on the fan blade facing the fan blade base. At this time, adjacent arc-shaped wind-blocking blocks abut against each other, thereby forming an annular structure that can gather wind, reduce wind diffusion, thereby enhancing wind force and improving the use effect of the fan; the arc-shaped wind-blocking block can also be installed on the fan blade away from the fan blade base according to user needs. When the fan blade base rotates to drive the arc-shaped wind-blocking block to rotate, the arc-shaped wind-blocking block fans to generate radial wind. The radial wind flows toward the drive component and the fan air outlet respectively under the obstruction of the fan body casing, which on the one hand improves the heat dissipation effect of the drive component, and on the other hand makes the wind more dispersed and the wind force softer and more comfortable.

[0008] Carbon fiber fan blades are also used. Carbon fiber material has the characteristics of light weight and high strength. Not only is it lighter, but it is also stronger, so that the fan blades can maintain better stability and durability when rotating at high speeds, and rotate more lightly, effectively improving the operating efficiency and performance of the fan, extending the service life of the fan, and also increasing the air volume and air pressure.

When the connecting column is threadedly connected to the threaded hole, the limit block is inserted into the limit groove, and the limit block abuts against the inner wall of the limit groove, thereby limiting the arc-shaped wind-blocking block and preventing the arc-shaped wind-block from rotating relative to the fan blades.
