Abstract
An atomizer includes a housing that has a plurality of atomizing nozzles which will atomize a solution containing small particles that are to be carried in an output aerosol. The atomizer nozzles are surrounded by a ring-like surface against which the atomized material impinges to collect large droplets and to cause secondary atomization of the liquid impinging on the ring-like surface. The ring-like surface can have many different cross-sectional configurations for obtaining different results in secondary atomization and droplet collection.
