Spray head nozzle uses compressed gas to atomize stream of liquid, has conical gas channel around opening of liquid channel

摘要

The liquid runs out of the container via an inner cylindrical neck (3). The conical outer cover (2) fits over the outer end of the neck, leaving a broad gas channel (5) lower down and a narrower channel around the cylindrical neck (3). The compressed gas flows over the cone of fluid (13) and forms an inverted cone (14) of expanding gas creates the atomized spray.
