Problems solved by technology

[0007] 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 impeller structure performance is low, the energy consumption is large, and the use cost is high

Embodiment Construction

[0031] The impeller of the traditional vacuum cleaner motor is made of aluminum, which is a closed impeller structure, usually including an upper cover, a lower cover, and blades arranged between the upper and lower covers. The closed impeller has a higher working efficiency, but It is difficult to manufacture, and the upper and lower cover plates and blades of the aluminum impeller are assembled, the structure is complex, the upper and lower cover plates are easy to loosen and damage, and generally the volume is large, the quality is heavy, the production cost is high, and the noise during operation larger. Moreover, generally the upper and lower cover plates are of flat plate structure, and the blades are evenly distributed between the upper and lower cover plates. In order to increase the working efficiency of the impeller, the length of the blades must be increased, so that the area of ​​the upper and lower cover plates needs to be enlarged, resulting in the Overall volume...

Abstract

An impeller, applicable in a brushless vacuum cleaner motor. The impeller comprises a lower cover (1). A gradual protrusion (5) is upwardly formed at the center of the lower cover (1). Both the upper and lower surfaces of the lower cover (1) form arced surfaces (6). The impeller (2) is fixedly arranged on the upper surface of the lower cover (1). The impeller comprises only the lower cover (1) and multiple arced blades (2) thereon, thus forming a semi-opened impeller. The impeller is relatively small in size, convenient to carry, and inexpensive to manufacture. The lower cover (1) is protruded upwards at the center thereof to form the arced surfaces (6), thus allowing the impeller to be structurally compact, and effectively reducing the size of the impeller. The impeller (2), the lower cover (1), and a central shaft (7) are integrally processed and molded, thus allowing for high structural strength and improved use performance.

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. 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 DC vacuum c...
