1.First press –When we first press the head, the head drives the sub-stem to compress the SPRING with the connected STEM;In the process of compressing the spring, the outer wall of the piston (PTSTON) rubs against the inner cavity wall of the body (HOUSING) to promote the piston to open the discharge hole of the sub-stem column (SUB-STEM);When the piston (PTSTON) slides down, the air in the HOUSING is discharged through the sub-stem discharge hole that has been opened;
2.Repeatedly press — to exhaust all the air in the body (HOUSING);
3.Actuator: Drawing — Actuator: Moving through the STEM,Sub STEM, Ptston, and SPRING together compress the air in the HOUSING and release the ACTUATOR. The SPRING moves back due to loss of pressure.At this time, the PISTON also moved down through the inner wall of the friction HOUSING to close the outlet hole of the sub-stem.At this time, the liquid storage chamber in the HOUSING forms a vacuum suction state. The glass BALL is sucked up, and the liquid in the bottle is sucked into the HORSING liquid storage chamber through a straw (DIPTUBE).
4.Storage of liquid –Press the head several times and store the liquid to the body through multiple suction until the liquid is full.
5.Liquid output –When the liquid in the HOUSING liquid storage chamber is full, the fluid is ejected directly from the ACTUATOR by pressing the head again through the discharge hole.
