Abstract

The invention discloses an electric fan and cleaning equipment. The electric fan comprises a shell assembly and a stator assembly. A cylindrical part is arranged on the outer wall of the shell assembly, a stator mounting part is arranged in the shell assembly, a diffusion channel is formed between the cylindrical part and the stator mounting part, and diffusion blades are arranged in the diffusion channel. The stator assembly is connected to the stator mounting part and comprises a stator iron core and windings, and the windings are connected to the stator iron core and protrude to the two axial ends of the stator iron core. And a fluid channel is formed between the stator iron core and the stator mounting part, and the fluid channel is communicated with the diffusion channel. When the electric fan runs, high-speed airflow flows through the diffusion channel and passes through the diffusion blades to reduce the flow speed and diffuse the pressure. The windings of the stator assembly can generate heat during operation, the fluid channel is arranged between the stator iron core and the stator mounting part, and the high-speed airflow flowing in the diffusion channel can drive the air in the fluid channel to flow, so that the heat is taken away, the windings are helped to dissipate heat, and the operation stability is improved.

Description

technical field [0001] The invention relates to the technical field of electric fans, in particular to an electric blower and cleaning equipment. Background technique [0002] In the related art, the electric fan in the hand-held vacuum cleaner is small in size and high in rotation speed. When the motor of the electric fan drives the impeller to rotate, a large vacuum is formed at the inlet of the fan cover, and the airflow is sucked in from the opening of the fan cover, and after obtaining a large kinetic energy through the flow channel of the impeller, it flows out through the diffuser at the rear . The stator assembly of the motor is arranged inside the electric fan, and the cooling conditions of the windings of the stator assembly are poor, which is not conducive to high-speed operation. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention propo...
