1. Press for the first time. When pressing for the first time, the lotion pump is tightened by the main column of the main column, and the auxiliary column is tightened; in the process of tightening the spring, the outer wall of the piston collides with the inner wall of the valve, prompting the piston to open the discharge hole of the column; When sliding down, the air in the valve body is expelled through the opening of the now open sub-post.
2. Press multiple times. Expel the air from the bottle. This step is required regardless of the type of lotion pump, including 5cc lotion pumps.
3. Aspirate the liquid. Press the pump head through the main column, sub-column, and piston, tighten the tension spring to discharge the air in the pump body, and then release the pressure head, the liquid storage cavity in the pump body constitutes a vacuum suction condition, and the glass ball is sucked up , the liquid in the bottle is sucked into the body fluid storage chamber through the straw.
4. Store liquids. After repeated pressure on the head and repeated suction, the fluid is stored in the body until the fluid stops completely.
