Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner motors, in particular to a motor rotor for a vacuum cleaner. Background Art

[0002] The vacuum cleaner motor is the core component of the vacuum cleaner. It is mainly responsible for generating suction and driving the fan to rotate, thereby sucking in dust and debris. The quality of the vacuum cleaner motor directly affects the cleaning effect and service life of the vacuum cleaner. Usually, the internal space of the vacuum cleaner is closed, the motor specifications are small, and the use intensity is high.

[0003] For example, the rotor structure and motor disclosed in publication number CN112713680A adopt this structural design, which eliminates the need to machine keyways, ridges, and other structures on the shaft, making the rotor structure more streamlined, which helps reduce the number of machining steps and the difficulty of machining, thereby reducing the cost of the rotor structure.

[0004] However, the above-mentioned motor and its internal rotor structure still have the following problems during actual use: this type of motor has a small internal space when working, but has a high intensity of use. Therefore, the continuously working rotor structure is prone to aggravating its heat generation under the effect of electromagnetic drive. The internal air duct space is small, which is not conducive to taking away the heat generated by the motor. At the same time, the various components of the rotor structure are easily damaged due to their own structure under high-speed rotation, thereby affecting the working efficiency and life of the rotor structure.

[0005] Therefore, we propose a motor rotor for a vacuum cleaner to solve the above problems. Utility Model Content
