⒈First press ------ When we press the head for the first time, press the head to compress the tension spring together through the connected main column and the moving auxiliary column; in the process of contracting the tension spring, the outer wall of the piston passes and conflicts 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;
⒉ Repeatedly pressing back and forth ------ Exhaust all the air in the body;
⒊Liquid absorption——Press the head by hand to pass the main column, sub-column, piston, and tighten the tension spring together to expel the air in the body, then loosen the head. The tension spring loses pressure and moves back (upper ) Movement. At this moment, the piston moves down through the inner wall of the conflict body to close the discharge hole of the auxiliary column; at this time, the liquid storage cavity in the body constitutes a vacuum suction condition, and the glass ball is sucked up, and the liquid in the bottle is passed through the straw Inhale the liquid into the liquid storage cavity of the body;
⒋Liquid storage------Press the head repeatedly, after repeated suction, store the liquid in the body until the liquid is full and stop; ⒌Liquid out------When the liquid in the body's liquid storage cavity is full , Press the head again and the liquid will be sprayed directly from the nozzle through the discharge hole.
