| description | The utility model relates to a fan and a fan impeller thereof, wherein the fan impeller comprises a wheel hub and a plurality of vanes; the vane is provided with an axial size and a radial size, and the vanes stretch outwards along the radial direction and the axial direction from the external surface of the side wall, so as to form a vane tip on the top of the vane and a vane tail, wherein the vane stretches from the external surface of the side wall along the radial direction; in the vane, the size of the vane becomes wider and wider from the vane tip to the vane tail, and the vane tip and the vane tail are all in an arc shape; the fan consisting of the fan impellers comprises a fan impeller, a guiding cover, a top wall, a guiding part, a central penetrating hole and an accommodating room; wherein the guiding part passes through an inversed round angel, is bent and stretches from the top wall to the central penetrating hole. The utility model is capable of increasing the wind quantity generated by the fan, |
