Dust collector motor

Abstract

The invention discloses a dust collector motor. The dust collector motor comprises movable impeller and an impeller cover; a sealing mechanism is arranged at the air inlet of the impeller cover; the sealing mechanism comprises a supporting part and a connecting part; the supporting part is fixedly connected with the edge of the air inlet and combined with the inner wall of the impeller cover to form an annular concave receiving space; the connecting part is fixedly arranged in the receiving space; the end portion of the upper piece of the movable impeller is rotatably embedded into the connecting part. According to the dust collector motor, the sealing mechanism is arranged at the matching part of the impeller cover and the movable impeller, and airflow sucked into the impeller cover is not prone to flow into the matching gap between the impeller cover and the movable impeller, and therefore, the energy efficiency of the motor is greatly improved.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaner manufacturing, in particular to a high-efficiency vacuum cleaner motor. Background technique [0002] In order to avoid bad rubbing between the impeller cover and the moving impeller in the existing vacuum cleaner motor, the gap between the moving impeller and the impeller cover is reserved. The impeller cover does not need to undergo any processing when assembling, and it is directly pressed in, and the airflow in the impeller cover is easily sucked. It flows into the matching gap between the impeller cover and the moving impeller, thus forming useless work and reducing the efficiency of the motor. According to the size of the gap, its impact on the efficiency of the motor is also different. At present, the efficiency of traditional vacuum cleaner motors is generally around 40%. . Contents of the invention [0003] The purpose of the present invention is to provide a vacuum cleaner moto...
