First press: When we press the head for the first time, the press head drives the auxiliary column to compress the spring together through the connected main column; in the process of compressing the spring, the outer wall of the piston rubs against the inner cavity wall of the body to prompt 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 opened secondary column discharge hole.
Press repeatedly to and fro: expel all the air in the body.
Liquid suction: After pressing the head with your hand through the main column, sub-column, piston, and the common compression spring to expel the air in the body, loosen the head, the spring loses pressure and moves back (up), and the piston also passes through at this time Rub the inner wall of the main body downward to close the discharge hole of the auxiliary column; at this time, the liquid storage cavity in the main body forms a vacuum suction state, suck up the glass ball, and suck the liquid in the bottle into the main liquid storage cavity through the straw Inside.
Storage of liquid: Press the head several times, and store the liquid in the body by repeatedly sucking the liquid until the liquid is full.
Liquid discharge: When the liquid in the liquid storage cavity of the body is full, press the head again and the liquid will be sprayed directly from the nozzle through the discharge hole.
