1.First press--------When we press the ACTUATOR for the first time, the press head drives the sub-stem through the connected main column (STEM) to compress the spring (SPRING) together; in the process of compressing the spring The outer wall of the piston (PTSTON) rubs against the inner wall of the body (HOUSING) to prompt the piston to open the discharge hole of the sub-column (SUB-STEM); when the piston (PTSTON) slides down, the air in the body (HOUSING) Discharge through the discharge hole of the opened sub-column (SUB-STEM);

2. Press reciprocatingly many times-to exhaust all the air in the body (HOUSING);

3. Liquid suction-------Press the head (ACTUATOR) by hand to pass the main column (STEM), sub-column (SUB-STEM), piston (PTSTON), and common compression spring (SPRING) to the body (HOUSING) After the air inside is discharged, release the ACTUATOR, the spring (SPRING) loses pressure and moves back (up). At this time, the piston (PISTON) also moves down through the inner wall of the friction body (HOUSING) to move the auxiliary column The discharge hole of (SUB-STEM) is closed; at this time, the liquid storage chamber in the body (HOUSING) forms a vacuum suction state, and the glass ball (BALL) is sucked up, and the liquid in the bottle is sucked into the liquid through the straw (DIPTUBE) Inside the body (HORSING) reservoir.

4. Liquid storage ------Press the head for many times, and store the liquid in the body through multiple suction until the liquid is full.

5. Liquid discharge-----------When the liquid in the body (HOUSING) storage cavity is full, press the head (ACTUATOR) again and the liquid will pass through the discharge hole directly from the mouth (ACTUATOR) Squirting.
