1. Press for the first time---------When we press the Bottle type foam dispensing pump head products for the first time, the press head drives the sub-column to compress the spring together through the connected main column; in the process of compressing the spring, the outer wall of the piston passes through the The friction of the inner cavity wall prompts 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 Bottle type foam dispensing pump head products is exhausted;

3. Suction ------- Press the bottle type foam dispensing pump head products by hand to discharge the air in the body through the main column, sub-column, piston, and the common compression spring, release the pressing head, the spring loses pressure due to , move back, at this time, the piston also moves down by rubbing the inner wall of the body to close the discharge hole of the sub-column; at this time, the liquid storage cavity in the Bottle type foam dispensing pump head products forms a vacuum suction state, and the glass ball is moved to Suction up, suck the liquid in the bottle into the HORSING liquid storage cavity through the straw.

4. Store liquid——Press the Bottle type foam dispensing pump head products several times, and store the liquid to the body through multiple suctions until the liquid is full.

5. Liquid discharge------------When the liquid in the liquid storage chamber of Bottle type foam dispensing pump head products is full, press the head again and the liquid will be sprayed directly from the nozzle through the discharge hole.
