AI Technical Summary

Technical Problem

When replenishing cleaning fluid or cleaning operations, the existing tooth flushing tank needs to occupy one hand to keep the cover open, which is more difficult to operate.

Method used

By designing a pluggable connection, the connection is kept in a specific position by using a retaining structure, forming a spacing between the cover and the opening, allowing both hands to operate the water tank.

Benefits of technology

Replenishing the cleaning solution or cleaning operation of the water tank without taking up both hands, which significantly reduces the difficulty of operation.
