Abstract

The invention belongs to the technical field of cleaning equipment, and particularly relates to a diffuser, an axial air supply device and a dust collector. The diffuser comprises a base ring piece, a plurality of first stationary blades and a plurality of second stationary blades, wherein the first stationary blades and the second stationary blades are connected to the base ring piece. The first stationary blades and the second stationary blades are arranged in the circumferential direction of the outer ring wall of the base ring piece, and at least one second stationary blade is arranged between every two adjacent first stationary blades. The height size of each first stationary blade in the axial direction of the base ring piece is larger than that of each second stationary blade in the axial direction of the base ring piece; and the height size of each first stationary blade in the radial direction of the base ring piece is larger than or equal to the height size of each second stationary blade in the radial direction of the base ring piece. In this way, the second stationary blades can effectively arrange the airflow flowing between the two first stationary blades at the two adjacent sides of the second stationary blades, the flowing separation phenomenon of the airflow is further weakened, the flowing loss of the airflow flowing through the diffuser is remarkably reduced, and then the pressurizing effect of the diffuser is remarkably improved.

Description

technical field [0001] The application belongs to the technical field of cleaning equipment, and in particular relates to a diffuser, an axial air supply device and a vacuum cleaner. Background technique [0002] With the improvement of people's living standards and the development of technology, vacuum cleaners, especially hand-held vacuum cleaners, are increasingly entering popular families. Air supply devices are arranged in the vacuum cleaners to realize the dust collection function of the vacuum cleaners. [0003] In the prior art, a diffuser is installed in the air supply device, and the diffuser usually has a plurality of stationary blades. When the air flow flows through the diffuser, there will be a short-term change in the flow direction from the radial direction to the axial direction. , which will cause the flow separation phenomenon to occur in the airflow near the outer wall of the diffuser, and the stator blades can guide the airflow and reduce the flow loss ...
