AI Technical Summary
In existing vacuum cleaners, the dust cup and filter cartridge are cleaned independently, resulting in low cleaning efficiency and incomplete cleaning, especially in removing hair, which leaves users with dirty hands.
A cleaning mechanism for a vacuum cleaner filtration system is designed. By setting a dust-removing ring inside the dust cup, a pusher is used to drive the dust-removing ring to slide axially. The dust and debris on the surface of the filter cartridge, the inside of the dust cup, and the inner sidewall are pushed upward to the cleaning port through its inner and outer circumferential surfaces, thereby achieving simultaneous cleaning of the filter cartridge and the dust cup and avoiding direct contact between the user and dust and hair.
It improves cleaning efficiency, prevents filter cartridge clogging, enhances airflow, reduces suction loss, protects the motor, reduces the frequency of user cleaning, and improves user experience.
