What is a lotion pump
The lotion pump is also known as a pressurised lotion pump. It is a liquid dispensing tool that uses the principle of atmospheric pressure balance to pop the liquid out of the bottle by pressing it, and can also replenish the outside atmosphere into the bottle.
How the lotion pump works
The head of the lotion pump is connected to a piston and is used by means of a compression spring. During the compression of the spring, the outer wall of the piston of the lotion pump is often opened fully by the friction of the inner chamber walls, while the discharge hole of the piston head is filled with liquid, and as the piston moves downwards, the air inside is discharged from the piston head.
How to use a lotion pump
The air inside the lotion pump can be completely removed by pressing the head several times, then pressing the head by hand, the air is removed from the lotion pump by the action of the piston joint and the compression spring. The piston moves downwards by rubbing against the inner wall to close the discharge hole, and the reservoir gun forms a hollow state, and the liquid inside the bottle is sucked into the reservoir cavity by the action of the suction tube. At this point, the liquid can be discharged directly from the nozzle through the discharge hole by pressing the head of the lotion pump again.
