How the hand sanitizer pump head works

1. Press for the first time---------When we press the press head for the first time, the press head drives the auxiliary column to compress the spring together through the connected main column; in the process of compressing the spring, the outer wall of the piston rubs against the inner cavity wall of the body, Propel the piston to open the discharge hole of the sub-column; when the piston slides down, the air in the body is discharged through the opened discharge hole of the sub-column;

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

3. Liquid suction--------Press the press head by hand through the main column, sub-column, piston, and the common compression spring to discharge the air in the body, then release the press head, the spring will return (upper) due to loss of pressure. ) movement, at this time, the piston also moves down by rubbing the inner wall of the main body, closing the discharge hole of the sub-column; at this time, the liquid storage cavity in the main body forms a vacuum suction state, sucking the glass ball up, and passing the liquid in the bottle through The suction tube sucks the liquid into the body's 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 body's liquid storage chamber is full, press the head again and the liquid will be directly sprayed from the nozzle through the discharge hole;
