      The working principle of lotion pump

　　1. Press-press the head, press the head through the auxiliary column and the compression spring connected with the compression spring, in the process of compressing the spring, the piston wall rubs against the car body through the inner wall, forcing the piston to open the vise column discharge hole; When the piston slides down, the air in the vehicle body is discharged through the discharge hole of the opened sub-pillar;

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

　　3. Inhalation-press the head into the main column, sub-column, piston, joint compression spring to discharge the air by hand. At this time, the head spring loosened by the pressure loss moves backward (upward), and the piston also passes through the car body wall It moves downward by friction, closing the discharge hole of the auxiliary column. At this time, the liquid storage cavity in the 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 of the body through the straw.

　　4. Storing liquid-press the head several times, and then store the liquid on the body through multiple suctions until the liquid is completely stored.

　　5. Discharge-When the liquid in the body fluid storage cavity is full, press the nozzle again to spray the liquid directly from the nozzle through the discharge hole.
