Abstract

A fan impeller includes a plurality of fan blade assembly members, each one of the fan blade assembly members respectively includes a metal ring bracket and a plurality of metal blades, one end of each one of the metal blades is respectively connected to the corresponding metal ring bracket and the plurality of metal blades of each one of the fan blade assembly members arranged radially to circumference the corresponding metal ring bracket. The metal ring brackets are configured to stack with each other and the metal blades are arranged in a radial centric row, a width of at least one portion of each one of the metal blades is not smaller than a distance between any two adjacent metal blades along a fan impeller circumferential direction. Accordingly, metal blades of a greater width can be densely arranged on the fan impeller.

First claim

What is claimed is:

1 . A fan impeller, comprising:
a plurality of fan blade assembly members, each one of the fan blade assembly members respectively comprising a metal ring bracket and a plurality of metal blades, one end of each one of the metal blades respectively being connected to the corresponding metal ring bracket and the plurality of metal blades of each one of the fan blade assembly members being arranged radially to circumference the corresponding metal ring bracket; wherein the plurality of metal ring brackets are configured to stack with each other and the plurality of metal blades are arranged in a radial centric row, a width of at least one portion of each one of the metal blades is not smaller than a distance between any two adjacent metal blades along a fan impeller circumferential direction.

2 . The fan impeller according to claim 1 , wherein another end of each one of the metal blades is respectively formed of a connecting structure.

3 . The fan impeller according to claim 2 , wherein the connecting structure is connected to the adjacent metal blade.

4 . The fan impeller according to claim 3 , wherein the connecting structure is locked onto the adjacent metal blade.

5 . The fan impeller according to claim 1 , further comprising an outer ring bracket, the outer ring bracket circumferencing each one of the metal ring brackets, and the outer ring bracket is respectively connected to each one of the metal blades.

6 . The fan impeller according to claim 5 , wherein another end of each one of the metal blades is respectively formed of a clamping engagement structure, and the clamping engagement structure is embedded at the outer ring bracket.

7 . The fan impeller according to claim 1 , further comprising a fan hub, and the plurality of metal ring brackets being embedded at the fan hub.

8 . The fan impeller according to claim 1 , further comprising a rotational axle assembly member, the plurality of metal ring brackets circumferencing the rotational axle assembly member, and the rotational axle assembly member being embedded at the fan hub.

9 . The fan impeller according to claim 1 , wherein each one of the metal blades is connected to an outer edge of the corresponding metal ring bracket.

10 . The fan impeller according to claim 1 , wherein a connecting area between each one of the metal blades and the corresponding metal ring bracket is bent.

11 . The fan impeller according to claim 1 , wherein an inner edge of the metal ring bracket includes a ring wall extended therefrom, and the reset of each one of the metal ring brackets are mounted onto the ring wall.
