Abstract: A detachable snap-fit hub assembly for electric fan, comprising a first member connecting to a motor and a second member connecting to fan blades, wherein said first member and second member are, respectively, provided with one or more sections of slide grooves and corresponding wedge protrusions, such that when said slide grooves fit tight with said wedge protrusions, said two members are accurately assembled together. Since said two members can be detached and assembled in a snap-fit manner, both transport of fans and assembly thereof are made simple and easy, and a high precision of fan assembly can also be ensured.
