How Perfume Sprayer PumpLotion Pump Works
1. Indenter - indenter, the indenter is pressed by the main column connected to the auxiliary column together with the compression spring. During the compression spring process, the piston wall rubs against the valve body through the inner wall, forcing the piston to open the auxiliary outlet hole; when the piston When sliding down, the air in the body is exhausted through the opened sub-column exhaust hole;

2. Press back and forth multiple times - fully press the air in the body;

3. Suction - manually press the head through the main column, auxiliary column, piston, and the joint compression spring to discharge the air in the main body. Due to the pressure loss, the head spring loosens and moves back (upward), and the piston also passes through the body wall at this time. The friction of the auxiliary column moves downward, and the discharge hole of the auxiliary column is closed; at this time, the liquid storage cavity in the main body forms a vacuum suction state, the glass ball is sucked up, and the liquid in the bottle is sucked into the liquid storage cavity in the main body through the straw.

4. Liquid storage - press the head several times, and store the liquid into the body through multiple suctions until the liquid storage is complete.

5. Discharge - When the fluid in the body fluid storage chamber is full, press the head again, and the fluid will be sprayed directly from the nozzle through the discharge hole.
