AI Technical Summary
The existing water tank structure of the cleaning device has problems such as cumbersome mechanical operation, easy fatigue, many parts, high assembly cost and reduced sealing. In particular, the traditional locking tongue mechanism is prone to wear under frequent opening and closing, which can lead to reduced sealing or accidental unlocking.
The design adopts a knob-driven limit block linkage lock tongue design, which allows the lock tongue to be inserted into or removed from the lock groove by rotating the knob, simplifying the operation process, enhancing sealing and reliability, and avoiding the need for changing the position of the fingers during operation.
It achieves smooth and convenient operation, improves user experience, reduces the risk of misoperation, has a compact structure, improves assembly efficiency and safety, and enhances sealing and service life.
