How the lotion pump head works

1. Press for the first time---------When we press the press head (ACTUATOR) for the first time, the press head drives the sub-post (SUB-STEM) through the connected main post (STEM) to compress the spring (SPRING) together; During the process, the outer wall of the piston (PTSTON) rubs against the inner cavity wall of the main body (HOUSING), prompting the piston to open the discharge hole of the sub-column (SUB-STEM); when the piston (PTSTON) slides down, the inner wall of the main body (HOUSING) will be removed. The air is discharged through the discharge hole of the sub-column (SUB-STEM) that has been opened;

2. Press back and forth for many times ------- all the air in the body (HOUSING) is exhausted;

3. Suction ------- Press the head (ACTUATOR) by hand through the main column (STEM), the sub-column (SUB-STEM), the piston (PTSTON), and the common compression spring (SPRING) to move the main body (HOUSING) After the air inside is discharged, release the pressing head (ACTUATOR), the spring (SPRING) moves back (up) due to the loss of pressure, at this time the piston (PISTON) also moves down through the inner wall of the friction body (HOUSING), and the auxiliary column is moved downward. The discharge hole of (SUB-STEM) is closed; at this time, the liquid storage cavity in the body (HOUSING) forms a vacuum suction state, sucks the glass ball (BALL) up, and sucks the liquid in the bottle through the pipette (DIPTUBE). Body (HORSING) liquid storage cavity.

4. Store liquid ------ Press the head several times, and store the liquid to the body through multiple suctions until the liquid is fully stored.

5. Liquid discharge ------- When the liquid in the liquid storage chamber of the body (HOUSING) is full, press the button head (ACTUATOR) again, and the liquid will pass through the discharge hole directly from the press mouth (ACTUATOR) squirting.
