Abstract

The invention discloses an impeller, a draught fan and a motor; the impeller (100) comprises a roughly-conical hub (11) and multiple blades (12) which are arranged on the outer circumference of the hub (11) at intervals in the circumferential direction; each blade comprises a front edge face on the inlet end and a rear edge face on the outlet end, the blades are flat plate twisted blades, and the blade front edge segments and the blade rear edge segments incline in a rotary twisted manner in the opposite directions in the circumferential direction; according to the impeller, the shape of the blades is optimized and designed, particularly, due to the fact that the blade front edge segments and the blade rear edge segments incline in the rotary twisted manner, convex faces and concave faces are formed on the same side faces of the blade front edge segments and the blade rear edge segments, fluid losses of the inlet ends and the outlet ends of the blades can be effectively reduced, the effective work range of the impeller is widened, and the work performance of the impeller is 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...
