Abstract

The invention provides an impeller, a fan and a dust collector, and relates to the technical field of mechanical equipment. The impeller comprises a first wheel disc, a second wheel disc, multiple first blades and multiple second blades. The first wheel disc and the second wheel disc are coaxially arranged, and the outer side of the first wheel disc is sleeved with the second wheel disc. The multiple first blades are fixedly connected between the first wheel disc and the second wheel disc. The multiple first blades are arranged in the circumferential direction of the first wheel disc at intervals. The multiple second blades are arranged on the outer side of the second wheel disc at intervals in the circumferential direction of the second wheel disc and fixedly connected with the second wheel disc. According to the impeller, the fan and the dust collector, the pressure ratio and the flow of the impeller are effectively increased, and therefore the fan efficiency of the fan is effectively improved, and then suction work of the dust collector is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and more specifically relates to an impeller, a blower fan and a vacuum cleaner. Background technique [0002] The vacuum cleaner sucks the dust on the surface to be cleaned by the vacuum action of the fan. As the core component of the fan, the impeller can change the performance parameters such as the flow direction, speed, pressure and flow of the gas, and form a vacuum at the inlet of the fan, so that the outside gas can be continuously sucked into the fan. The impeller includes a disc and blades fixed on the disc, wherein the blades are driven by the disc to rotate and generate disturbance to the air flow, so that the air flow is accelerated and pressurized, and discharged from the outlet. The associated impeller structure pressure ratio and flow rate are low, resulting in low fan efficiency of the fan. Contents of the invention [0003] In view of this, the present invention...
