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 employs multiple three-way comb teeth near the suction port, including a first comb tooth section and two second comb tooth sections, which hook slender objects along the circumference and axial direction of the roller brush respectively to prevent entanglement, and reduce friction and ensure unobstructed airflow through preset gaps.

Benefits of technology

It effectively prevents long, thin objects such as hair from getting tangled in the roller brush, improving cleaning efficiency, reducing the risk of damage to the roller brush and the internal structure of the machine, and reducing noise and drive load.
