AI Technical Summary

Technical Problem

Existing drinking water filters have poor sealing between the filter cartridge housings, leading to water leakage and potential indoor flooding. Furthermore, current technology lacks effective monitoring and alarm mechanisms.

Method used

The upper drainage plate directs the leaking water into the middle water immersion sensor. When the middle water immersion sensor is powered on, it activates the audible alarm device to monitor and alarm for water leakage from the filter cartridge housing. Combined with the inner scraper, it cleans the attached filter material to prevent clogging.

Benefits of technology

It enables timely monitoring and alarm of water leakage in the filter cartridge housing, preventing indoor flooding, extending the service life of the filter cartridge, and maintaining water flow.
