1. A fan, comprising:
a hollow direct-current brushless motor and
a plurality of fan blades;
wherein the plurality of fan blades are disposed on a rotating housing and rotate along with the rotating housing;
wherein the hollow direct-current brushless motor comprises a center shaft, the rotating housing, a stator, a driver, and a permanent magnet;
wherein the center shaft is of a hollow structure, a wire passing channel allowing power lines to pass through is defined in the center shaft, a through hole communicated with the wire passing channel is defined on one side of the center shaft; the rotating housing is rotatably sleeved on an outer side of the center shaft, an accommodating cavity is formed in the rotating housing; the stator is fixed on the center shaft and is disposed in the accommodating cavity; the driver is fixed to the stator and is disposed in the accommodating cavity, the driver is disposed beside the through hole; and the permanent magnet is fixed to an inner side wall of the accommodating cavity and is disposed on an outer periphery of the stator;
the plurality of fan blades are fixedly clamped with the rotating housing;
wherein positioning embedding grooves are defined on an outer wall of the rotating housing; a snapping groove is concavely defined on a bottom surface of each of the positioning embedding grooves; each of the plurality of fan blades comprises a base plate and a blade, the base plate and the blade of each of the plurality of fan blades are integrally formed and connected; each base plate is matched with a corresponding positioning embedding groove and is embedded in the corresponding positioning embedding groove for positioning; an elastic snapping portion is disposed on and protruded from each base plate; each elastic snapping portion is fixedly snapped on a corresponding snapping groove.
