The Working Principle Of Foam Pump Head

Dec. 11, 2018

In life, we often use foam facial cleanser, foam hand lotion, foam shampoo, so why can the liquid become foam after it is squeezed out? This is due to the foam pump head. The working principle of the Plastic Foamer Pump head is to use atmospheric pressure. Let Plastic Foamer Pumps Factory give you a brief introduction to how the foam pump head works.

When using a foaming hand lotion or a foaming facial cleanser, first press the air in the liquid storage chamber (that is, the plastic tube that can suck the liquid), and when the air is exhausted, press the pump head again, because after releasing the hand, When the spring in the pump head is restored to its original state, a vacuum will be formed in the liquid storage chamber to generate a negative pressure. At this time, the pressure in the container is consistent with the atmospheric pressure, so that the pressure in the liquid storage chamber is small and the pressure inside the container is large. At this time, due to the pressure difference, the atmosphere will press the liquid around the reservoir cavity into the reservoir, and the foam will be squeezed out.
