Fan blade, fan and blowing equipment

The fan blade comprises a hub and a blade body, the blade body is provided with a hollow area and comprises a first segment and a second segment which are arranged on the two opposite sides of the hollow area respectively, and the first segment and the second segment are arranged in the circumferential direction and/or the axial direction of the hub at intervals. The inner end of the first segment and the inner end of the second segment are respectively connected with the hub, and a hollow area is defined among the first segment, the second segment and the hub; the first segment is provided with a first rear edge and a first front edge which are sequentially arranged in the rotating direction of the fan blade, the second segment is provided with a second rear edge and a second front edge which are sequentially arranged in the rotating direction of the fan blade, and the bending and sweeping direction of the first front edge is the same as the bending and sweeping direction of the second front edge. According to the technical scheme, the aerodynamic noise of the fan blades can be reduced.
