The invention discloses an electric fan and a blower applying the same. The electric fan comprises a rotor, an impeller and a stator, wherein the rotor and the impeller are integrally mounted with a rotating shaft, and the stator is in electromagnetic coupling connection with the rotor; the electric fan further includes an outer shell located on the periphery and an inner shell capable of rotatingrelatively and installed on the periphery of the rotating shaft, and a plurality of diffusion blades are arranged between the outer shell and the inner shell; and the inner shell is located between the stator and the impeller, and meanwhile, a backflow sheet for reducing airflow loss is mounted between the stator and the inner shell. Through the specific backflow sheet structure design, the internal flow transmission of the electric fan is smoother, the air pressure is higher, the airflow loss problem in the shell can be effectively solved, and the airflow noise is reduced while the working efficiency is improved.
Description
technical field [0001] The invention belongs to the field of fans, and in particular relates to an electric fan, and also relates to a hair dryer used by the electric fan. Background technique [0002] As a hand-held electrical product for daily use, people hope that the hair dryer has a good compact installation structure, low noise and high work efficiency, so that users can obtain a good use experience. As the core working part of the hair dryer, the electric fan directly determines the relative performance of the hair dryer in terms of installation structure compactness, noise and work efficiency. [0003] The electric fan mainly includes structural parts such as a stator, a rotor, and an impeller installed through the shell. Its specific working principle is mainly to drive the rotor to rotate through the electromagnetic coupling between the stator and the rotor, and then drive the impeller to rotate, thereby realizing blowing. Effect. In order to improve the diffusio...
