We always use many lotion pump heads in our lives, so we will introduce you to the working principle of today's lotion pump.
1. First press-When we press the press head for the first time, the press head drives the auxiliary column to compress the springs together through the connected main column. In the process of compressing the spring, the outer wall of the piston pushes the piston by friction with the inner wall of the main body 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.
2. Press repeatedly-to expel all the air in the body.
3. Inhale, press the indenter by hand to expel the air in the body through the main column, auxiliary column, piston, and common compression spring. Release the pressure head. Due to the pressure loss, the spring moves backward (upward). At this time, the piston also moves downward through the inner wall of the friction body to close the discharge hole of the auxiliary column. At this time, the liquid storage cavity in the body is in a vacuum liquid absorption state, the glass ball is sucked upward, and the liquid in the bottle is sucked into the liquid storage cavity of the body through the straw.
4. Store liquid-press the pressure head several times, and then store the liquid in the body by pumping the liquid several times until the liquid is completely stored.
5. Discharge-When the liquid in the liquid storage cavity of the human body is full, press the pressure head again, and the liquid will be directly discharged from the pressure nozzle through the discharge hole.
