[0002] The large stroke movement of the plunger pump simulates the vaccine dispensing process, mainly through the reciprocating movement of the plunger in the cylinder to realize the suction and discharge of the liquid medicine, so as to complete the accurate dispensing of the vaccine. When the plunger pump moves outward, the pressure in the working cavity is reduced, and the rotation of the pump rod triggers the opening of the inlet valve and the closing of the outlet valve, and the liquid medicine is sucked into the cavity. When the plunger pump is pushed inward, the pressure in the working cavity is increased, and the pump rod is rotated, the outlet valve is opened, and the inlet valve is closed, and the liquid medicine is discharged and enters the filling container.
