Abstract

The invention discloses an impeller, a fan and a motor. The impeller (100) comprises an approximately-conic hub (11) and multiple blades (12) arranged on the outer circumferential face of the hub (11) at intervals in the circumferential direction. Each blade comprises a front edge face located at the inlet end and a rear edge face located at the outlet end. Each blade is a flat plate twisted blade. The blade rear edge segment of each blade is rotationally twisted and inclined relative to the circumferential direction. In the impeller, the shapes of the blades are subjected to optimization design, especially on the rear edge segments, the rear edge segments of the flat plate twisted blades are rotationally twisted and inclined by a certain angle relative to the circumferential direction, so that a concave face and a convex face are formed on the two side faces of the rear edge segment of each blade correspondingly, fluid losses at the outlet ends of the blades can be effectively reduced, the effective working range of the impeller can be expanded, and the working performance of the impeller can be greatly improved.

Description

technical field [0001] The invention belongs to the field of impellers, and more specifically relates to an impeller and a fan and a motor with the same. Background technique [0002] In the vacuum cleaner, the motor drives the impeller to rotate at a high speed to form a negative pressure environment in the sealed housing, so that dust and the like are sucked into the dust collection device, so as to achieve the cleaning effect. Among them, the moving impeller is a key component of the vacuum cleaner, and its performance directly determines the overall working efficiency of the fan system. [0003] However, vacuum cleaners in the prior art generally have the disadvantages of large fan volume and low performance, and it is necessary to continuously optimize the design of the impeller structure to further improve the working performance of the vacuum cleaner. Contents of the invention [0004] In view of the above defects or deficiencies in the prior art, the present inven...
