An atomizer nozzle is the heart of a tool that generates a spray of liquid mist. It can take many forms. The first atomizer nozzle, also called an aspirator nozzle, was invented by Dr. Thomas DeVilbiss of Toledo, Ohio, in the late 19th century for producing a fine spray of a liquid based on the Venturi effect. His device was used for spraying medicine on the back of his patients' throats. Atomizer nozzles can create atomization from a variety of mechanical means including electrostatic processes, ultrasonic nozzle and centrifugal forces.
Principle of operation
The difference between the reduced pressure at the top of the tube and the higher atmospheric pressure inside the bottle forces the liquid from the reservoir up the tube and into the moving stream of air where it is dispersed into small droplets (not individual atoms as the name suggests) and carried away with the stream of air.
