Bionic axial flow wind wheel

The invention discloses a bionic axial flow wind wheel. The bionic axial flow wind wheel comprises a hub and blades installed on the circumferential side wall of the hub. The blade material of the wind wheel is one of plastic and metal or a combination of both. Each blade comprises a blade root and a blade top, wherein the blade root is the part being in contact with the hub, and the blade top isthe part opposite to the blade root and away from the blade root. Each blade further comprises a blade front edge and a blade rear edge opposite to the blade front edge, wherein the contour line at the blade front edge comprises at least two curves with opposite bending directions in the direction from the blade front edge to the blade rear edge. The blade tops and the partial areas close to the blade tops are arranged in a deflection manner in the direction of the suction faces of the blades, and therefore the areas, close to the blade tops, of the blades are deflected to form deflection parts.
