Background

A spray pump is a pump for spraying a liquid content in a spray state, and is widely used in the field of a cosmetic container. The working principle is that the air in the liquid storage cylinder is discharged by utilizing the movement of the piston to cause the difference of the internal air pressure and the external air pressure, so that the liquid rises under the action of the air pressure and is sprayed out through the nozzle of the press head. When the pressing head is pressed downwards by hand, the spring is compressed to close the liquid inlet valve (marble) downwards, and simultaneously, the air exhaust valve (through hole of the piston rod) is opened because the piston moves downwards, so that the liquid in the liquid storage cylinder rises and is sprayed out through the nozzle of the pressing head; when the hand is released, the spring returns to the original natural state, so that the piston moves upwards, the exhaust valve is closed, the liquid inlet valve is opened, and liquid enters the liquid storage cylinder from the liquid guide pipe through the liquid inlet valve under the action of the external atmospheric pressure. Thus, the piston reciprocates up and down in the cylinder to continuously suck the liquid up and spray the liquid out through the nozzle of the pressing head.
