[0001] The utility model relates to the technical field of liquid dispensers, in particular to a liquid dispenser capable of quickly and safely dispensing liquids at different controllable positions. Background Art

[0002] In surface treatment and coating lines like degreasing, phosphating, electrophoresis, autophoresis, and electroplating, the working fluids in each process are typically stored in large tanks. To ensure consistent production quality, these working fluids must be sampled, tested, and analyzed. This is especially true in electrophoresis tanks, where the fluid is constantly circulating and agitated while energized. During actual sampling and analysis, samples must be collected at varying depths within the tank, and this must be accomplished quickly while energized. Therefore, a liquid dispenser that meets these requirements is crucial.

[0003] In practice, however, sampling can only be done on the surface of the electrophoresis tank using tools such as a scoop, or some tanks are equipped with fixed pipes and valve sampling ports, where the valves are opened to take samples. Currently, there is a lack of such a fast and safe liquid sampling device that can be controlled at different positions on the market. Utility Model Content
