1. First press--------When we press the Screw Lotion Pump for the first time, press the head to drive the sub-column together to compress the spring; in the process of compressing the spring, the outer wall of the piston rubs against the inner wall of the body. Urging 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 discharge port of the sub-column that has been opened;
2. Reciprocating multiple presses ------- all the air in the body is discharged;
3. Aspirate ------- Press the 410 Foam Pump by hand and pass the main column, the secondary column, the piston, and the common compression spring to discharge the air inside the body, then release the pressing head, the spring loses pressure and goes back (on Movement, at this time, the piston also moves downward through the inner wall of the friction body, and the discharge hole of the sub-column is closed; at this time, the liquid storage chamber of the body forms a vacuum suction state, sucks the glass ball upward, and passes the liquid in the bottle. The straw draws liquid into the body reservoir.
4. Store the liquid ------ press the head several times, and store the liquid to the body by multiple aspirations until the liquid is full.
5. Discharge-----------When the liquid in the body liquid storage chamber is full, press the head again, and the liquid is directly ejected from the nozzle through the discharge hole;
