The lotion pump, also known as the push-type lotion pump, is a liquid dispenser that uses the principle of atmospheric balance to pump out the liquid in the bottle by pressing and replenishing the external atmosphere into the bottle.

01. the working principle of the lotion pump

When the pressing head is pressed for the first time, the pressing head drives the piston head to compress the spring together through the connected connecting rod; in the process of compressing the spring, the outer wall of the piston rubs against the inner cavity wall of the cylinder, which causes the piston to open the discharge hole of the piston head; the piston goes down When sliding, the air in the cylinder is discharged through the discharge hole of the piston head that has been opened.

Press several times to exhaust all the air in the cylinder.

Press the pressing head by hand to discharge the air in the cylinder through the connecting rod, the piston head, and the piston, and compress the spring together to discharge the air in the cylinder, then release the pressing head, the spring moves back (up) due to the loss of pressure, and the piston also rubs the inner wall of the cylinder at this time. Move down to close the discharge hole of the piston head. At this time, the liquid storage chamber in the cylinder forms a vacuum suction state, the ball valve is sucked up, and the liquid in the bottle is sucked into the cylinder liquid storage chamber through the straw.

Press the pressing head several times, and store the liquid into the cylinder through several suctions until the liquid is full.
