AI Technical Summary

Technical Problem

The existing electric cleaning brushes have insufficient structural stability in the connection between the body and the brush head, resulting in loose connections and brush head misalignment, which affects the cleaning effect.

Method used

It adopts an assembly hole design for the output shaft and rotating cover, and achieves a limiting connection between the output shaft and the rotating cover through a support rod. The friction is enhanced by a knurled structure, and combined with the detachable brush head design, it supports the replacement of various brush heads.

Benefits of technology

It improves the stability and efficiency of power transmission, enhances the compactness of the structure, broadens the application scenarios, and improves the cleaning effect and adaptability.
