Electric fan and cleaning equipment

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 o
