FIELD: apparatus for spraying or atomizing liquids or other fluent materials, particularly in medicine and sanitation for inhalation therapy, room moistening and disinfection.
SUBSTANCE: ultrasound aerosol generator comprises aerosol chamber composed of upper and lower parts and ultrasonic transducer installed in lower chamber part. Ultrasonic transducer is also used as container for working liquid. Piezoelectric ultrasound emitter is sealed in transducer bottom. Air inlet orifice provided with fan is formed in side wall or bottom of lower chamber part. Supplying device used to maintain necessary level in transducer cup is arranged in upper chamber part. Aerosol discharge channel is located above the transducer and arranged coaxial thereto. Aerosol discharge channel is formed as a tube with end located above working liquid level. Generator created aerosol particles having dimensions of 0.1 - 10 mcm.
EFFECT: possibility to obtain fine aerosol particles, provision of practically laminar aerosol flow and full discharge thereof due to recombination processes elimination, namely due to prevention of fine aerosol particles conversion into large ones by conglutination thereof.
