A perfume sprayer uses the mechanism of positive displacement pumps?
Like positive displacement pumps, perfume sprayer or atomizer displaces regular amount of volume. Every time we push the sprayer, a certain volume is being ejected out of the perfume bottle and is released in the open air. At the same time, another batch of liquid is being sucked inside the tube where the next batch of liquid to be displaced rests.
As you can observe when wearing perfume, each time we push the sprayer, the liquid that is brought out are made into small molecules of liquid. This process is called atomizing. It is not the whole liquid that is being squirted out but rather small molecules of it.
This is a picture of the nozzle. A tube is dipped in the bottle where the liquid perfume is reserved. After pressure is applied at the sprayer, it then releases the liquid that is inside the tube and part of the liquid that is reserve is then suck into the tube. It is because of the horizontal air that passes over a vertical tube that causes the air and liquid in the vertical tube to be pulled upward.
