How Does An Lotion Pump Work?

First press: when we press the lotion pump for the first time, the lotion dispenser pump compresses the spring together with the secondary column by means of the connected main column; during the compression of the spring, the outer wall of the piston opens the discharge hole of the secondary column by friction with the inner cavity wall of the body; when the piston slides downwards, the air inside the body is discharged through the already opened discharge hole of the secondary column.；

Repeated presses: all the air in the lotion pump bottle is expelled.

Liquid suction: press the lotion pump dispenser by hand through the main column, the secondary column and the piston, together compressing the spring to expel the air from the lotion bottle with pump, then release the lotion pump head and the spring moves back (up) as it loses pressure, at this time the piston also moves down by rubbing against the inner wall of the body, closing the discharge hole of the secondary column; at this time the liquid storage cavity in the pump lotion bottle forms a vacuum suction state, sucking the glass ball upwards and drawing the liquid inside the bottle into the body through the suction tube. in the reservoir cavity.

Storage of liquid: Press the press lotion pump head several times to store the liquid in the body by repeated aspiration until the liquid is full.

Discharge: When the liquid in the body is full, pressing the press head again causes the liquid to be discharged directly from the press nozzle through the discharge hole.

In short, it means that when you press the lotion pump head, the bead goes up and the liquid is sucked into the tube, when you let go the bead comes down and the liquid stays above the bead, no liquid comes out for the first time; press it again, the suction tube feeds the liquid and then tops out the liquid sucked in for the first time, repeatedly circulating, a constant source.
