ABSTRACT:
An effective nebulizer atomizes fluids or powders carried in a stream of pressurized gas. The nebulizer includes a casing, a nozzle head having at least one gas outlet and a reservoir disposed around the at least one gas outlet for receiving the substance to be atomized, and from which the substance is atomized by the steam of gas. The substance to be atomized is introduced into the nebulizer, at least two holes opening into the reservoir through which the substance to be atomized is drawn by the stream of gas issuing from the at least one gas outlet. Also provided is an airflow control device having a bridge bar which is locatable for interception of the gas issuing from the at least one gas outlet so as to be freely angularly displaceable for deflecting the stream of gas issuing from the at least one gas outlet across the reservoir.
