During transportation, the servo motor drives the threaded rod to rotate, and the threaded rod drives the slider and the rubber piston sleeve to move up and down, thereby opening the six groups of conveying slots on the slide, and then improving the liquid transportation efficiency and response speed. Later, when the dispenser needs to be repaired, the four groups of screws are removed, and then the card-mounted top shell is removed, and then the liquid dispenser can be maintained and repaired. Then, the top shell and the bottom shell are re-installed through the card-mounted assembly and the sealing assembly, and then they are re-fixed with four groups of screws, and then the dispenser can be used.
