1.The first press------When we press the head for the first time, the head passes through the connected main column and moves the auxiliary column to tighten the tension spring together. During the process of tightening the tension spring, the outer wall of the piston collides with the inner cavity wall of the body. Promote the piston to open the discharge hole of the auxiliary column; when the piston slides down, the air in the body is discharged through the discharge hole of the auxiliary column that is now open;
2.Repeated reciprocating presses------Exhaust all the air in the body;
3.Liquid absorption----Press the head by hand through the main column, auxiliary column, piston, and tighten the tension spring together to expel the air in the body, release the pressure head, the tension spring returns to the upper side because of the loss of pressure (up ) Movement, at this moment the piston moves downward through the inner wall of the conflicting body, closing the discharge hole of the auxiliary column; at this time, the liquid storage chamber in the body constitutes a vacuum suction state, sucking the glass ball upward, and passing the liquid in the bottle through the straw Inhale the liquid into the liquid storage cavity of the body;
4.Storage of liquid --- repeatedly press the button, after repeated suction, store the liquid to the body until the liquid storage is full;
5.Exiting liquid ------When the liquid storage cavity of the body is full, press the pressing head again and the liquid will be ejected directly from the pressing nozzle through the discharging hole.
