AI Technical Summary

Technical Problem

In continuous pulsating vacuum cleaning machines, floating debris from the cleaning process can accumulate and interfere with the cleaning effectiveness, potentially being carried over to subsequent cleaning stages if not promptly collected.

Method used

A self-filtering system comprising a transmission cam component, transmission axis adjustment board, filter net longitudinal and transverse guides, filter net, and filter net fixing components, driven by an external motor via a chain mechanism, allowing the filter net to open and close to collect floating debris within the cleaning tank.

Benefits of technology

Effectively collects and retains floating contaminants during the cleaning process, preventing them from re-depositing on the equipment and ensuring improved cleaning efficiency by maintaining the filter net in the optimal position for debris collection and water drainage.
