AI Technical Summary

Technical Problem

Existing vacuum cleaners' airflow design focuses on the negative pressure area directly in front of the suction port, causing the brush edge area at the rear of the floor brush to be at the edge of the airflow. Dust cannot be effectively drawn into the air duct system, resulting in secondary pollution that requires manual cleaning by the user, affecting cleaning efficiency and user experience.

Method used

Design a self-cleaning floor brush structure. A cleaning brush driven by a drive unit is installed on the base. The cleaning brush contacts the bristles of the floor brush, rotates to clean the dust on the bristles, and sucks the dust into the dust cup of the vacuum cleaner. The vacuum cleaner's main unit uses suction to collect the debris.

Benefits of technology

It eliminates the need for users to manually clean the brush bristles, avoids secondary pollution, and improves cleaning efficiency and user experience.
