Impeller structure

Abstract

The invention discloses an impeller structure, which comprises a lower cover plate and a plurality of arc-shaped blades, wherein the arc-shaped blades are arranged on the lower cover plate, and the blades are connected with an axis and are distributed along the lower cover plate in an involute way. The impeller structure has the advantages that the impeller structure is suitable for high-vacuum and high rotation speed brushless direct current dust collector motors; the impeller structure is of a semi-opening type impeller structure, so the size is relatively smaller, and the carrying is convenient; the use amount of material is little, and the production cost is lower; the blades are distributed on the lower cover plate in the involute way, so the running is stable, the working property is better, the energy consumption is little, the use cost is lower, the noise is little, and the quality of working environment is higher; an impeller cover is arranged above the impeller, the blades are in clearance fit with the blade cover, the impeller cover is also used as an upper cover plate, and a closed type impeller structure is formed among the upper impeller cover, the lower cover plate and the blades, so while the size of the motor is reduced, the working efficiency of the impeller is guaranteed, and the use requirements of small size and high rotation speed of the motor are met; the blades and the lower cover plate are integrally formed, so the structure strength is higher.

Description

technical field [0001] The invention belongs to the technical field of production and manufacture of vacuum cleaner motors, and in particular relates to an impeller structure. Background technique [0002] The vacuum cleaner is a cleaning appliance that uses a motor to drive the blades to rotate at high speed, and generates air negative pressure in the sealed housing, thereby sucking dust into the dust bag. Vacuum cleaners can generally be divided into vertical, horizontal and portable according to their structural composition. [0003] The vacuum cleaner motor is the core component of the vacuum cleaner. It generally consists of two parts, the motor part and the fan part. Because the vacuum cleaner motor has high requirements on the speed, usually at 20,000-30,000 revolutions per minute, the conventional vacuum cleaner motor generally uses a series-excited vacuum cleaner motor. and small DC vacuum cleaner motors. Both the series-excited vacuum cleaner motor and the small D...

Problems solved by technology

[0006] In order to reduce the overall volume of the vacuum cleaner, it is generally driven by a brushless motor. In order to meet the use requirements of the brushless motor, the impeller structure generally needs to be made smaller. The traditional aluminum closed impeller is no longer suitable for the brushless motor, and the traditional The structural performance of the impeller is low, the energy consumption is large, and the use cost is high
