Abstract

The invention relates to a motor device for a vacuum cleaner. The diffuser assembly includes a wind deflector, a centrifugal wind wheel and a wind cover; the front end of the wind cover is an air inlet, and a plurality of air outlets are arranged around; the output shaft of the motor passes through the front bracket and the wind guide in sequence. The front end of the output shaft fixes the centrifugal wind wheel with the help of nuts; the output shaft is provided with a sleeve at the position just protruding from the front bracket, so that the output shaft is rotatably supported on the front bracket; the front bracket is generally hollow Cylindrical, most of its outer peripheral flange is an annular plane, and the front side of the annular plane is provided with an annular groove; the rear side of the wind deflector is provided with an annular protrusion matching the annular groove, and the annular protrusion is embedded in the In the annular groove; the front end surface of the air deflector is formed with an air flow channel from the inside to the periphery to guide the air flow axially away from the centrifugal fan wheel. The technical effect of the invention lies in: simplified structure, low manufacturing cost; reduced noise, improved work efficiency; low noise, high stability and the like.
