Abstract
A method of atomizing a liquid comprising providing the liquid to a liquid duct in a dispensing body, providing a gas to a gas duct in the dispensing body, and introducing the liquid into a head via a plurality of liquid duct channels. The method further includes introducing the gas into a pressure chamber of a pressure cap, the pressure cap positioned proximate the dispensing body such that the head is positioned between the pressure cap and the dispensing body. The gas is expelled through a plurality of pressure chamber exit orifices, the pressure chamber exit orifices positioned proximate a plurality of liquid supply channel exit openings via an alignment spacer defined on the head. The method includes expelling the liquid from the liquid supply channel exit openings and through the pressure chamber exit orifices, such that the liquid and the gas interact and form atomized droplets of the liquid.
