Emulsion pump is the principle of the use of atmospheric pressure

Use of time, we first through the pressure, the liquid storage chamber (that is, the shampoo can suck plastic pipe) in the air, when the air after the row, press the pump head again, due to let go, the pump head spring to return to original state, so will form a vacuum in the liquid storage chamber, produce negative pressure, at this time, the pressure and atmospheric pressure in the container remains consistent, so, just in the liquid storage chamber pressure is small, the status of the container pressure, at this time, due to the pressure difference, the atmosphere will give pressure around the mouth of liquid liquid storage chamber into the liquid storage chamber, the sense that gives a person is like a pump the liquid suction head.
