Flow guide structure, electric fan assembly and dust removal equipment

The embodiment of the utility model provides a flow guide structure, an electric fan assembly and dust removal equipment. The flow guide structure comprises a body and at least two flow guide pieces. An air duct is arranged in the body, and the two axial ends of the air duct are an air inlet end and an air outlet end respectively; the flow guide pieces are arranged on the peripheral wall of the air duct at intervals and extend in the axial direction of the air duct. The connecting line between the front edge, close to the air inlet end, of the flow guide part and the rear edge, close to the air outlet end, of the flow guide part forms an included angle with the central axis of the air duct. After the flow guide structure is used for the electric fan assembly, the noise of the electric fan assembly can be reduced, so that the experience feeling of a user is improved, in addition, the flow guide structure can improve the flow field quality of the electric fan assembly, and therefore the efficiency of the electric fan assembly can be improved to a certain extent.
