Description

Technical Field

[0013]

[0001] The utility model specifically relates to a turbine structure of a vacuum cleaner motor. Background Technique

[0002] The vacuum cleaner motor is one of the core components of the vacuum cleaner, responsible for driving the turbine and generating suction force, enabling the vacuum cleaner to effectively clean dust and dirt. The turbine usually refers to a wind wheel structure on the motor, mainly used to drive the air flow.

[0003] Most of the existing vacuum cleaner motor turbines are integral, and the blades on the turbine cannot be disassembled. This results in the scrapping of the entire motor turbine after one of the blades is damaged, with a relatively high usage cost. Moreover, due to the large twist of the turbine blades, the cleaning effect on the blades with a longer axis is not good, and it is impossible to disassemble and clean and maintain the blades. For this reason, we propose a turbine structure of a vacuum cleaner motor. Content of the Utility Model
