The working principle of Lotion Pump :

1. First press: When we press the push button for the first time, the push button drives the auxiliary column to compress the spring together through the connected main column; during the compression spring, the outer wall of the piston frictions with the inner cavity wall of the body to cause the piston to open the auxiliary column. Feed hole; when the piston slides down, the air in the body is discharged through the discharge hole of the auxiliary column that has been opened;

2. Multiple reciprocating presses: all the air in the body is expelled;

3. Liquid absorption: press the head by hand through the main column, auxiliary column, piston, and jointly compress the spring to expel the air in the body, release the button, the spring moves back (up) due to the loss of pressure, and the piston Similarly, by sliding down the inner wall of the body, the discharge hole of the auxiliary column is closed; at this time, the liquid storage chamber in the body forms a vacuum suction state, sucking the glass ball upward, and sucking the liquid in the bottle into the body storage through the suction pipe In the liquid chamber.

4. Storage liquid: Press the button multiple times, and store the liquid to the body through multiple suctions until the liquid is full.

5. Discharge: When the liquid storage cavity of the body is full, press the button again and the liquid will be directly ejected from the nozzle through the discharge hole.
