AI Technical Summary

Technical Problem

The roller brushes of existing robotic vacuum cleaners are prone to clogging during cleaning due to tangling of long, thin objects such as hair and fuzz, which reduces cleaning efficiency and increases the risk of damage to the internal structure of the machine.

Method used

Design a roller brush mechanism that uses a spiral roller brush with an L-shaped comb tooth structure. The comb teeth untangle tangled hair and fur through circumferential and axial movement. A preset gap is set to reduce friction and ensure unobstructed airflow.

Benefits of technology

It effectively prevents hair and lint from getting tangled, improves cleaning efficiency, reduces the risk of damage to the roller brush and internal machine structure, and ensures reduced dust collection efficiency and noise.
