Abstract: The invention relates generally to a mesh type apparatus for liquid atomizing and filtration, for example, of the atomizer having a concave ultrasonic transducer, which also forms a part of the liquid container (1). This transducer is emitted an ultrasonic energy which created a spout (2) of the liquid (3) to be atomized. The liquid (8) plays a role of the transmission media. The container (9) with liquid (3) is set up on the top of the container (1). The liquid (3) is separated from the transmission media (8) through the bottom of the container (9) by a material that has minimum attenuation of ultrasonic energy. This separation could be temporary or permanent. The focal zone extender (7) is placed in the vicinity of the bottom of container (9). In this case all liquid above the bottom of the focal zone extender will be forced up to the top of the focal zone extender and atomized at the constant intensity of acoustical energy conveyed from the bottom of the focal zone extender.

Abstract: A sterilization apparatus designed to receive an article requiring sterilization in which the apparatus comprises an aerosol generator operatively coupled to a sterilization chamber. The aerosol generator includes an ultrasonic transducer which is electrically coupled to an ultrasound generator. The sterilization apparatus also includes a tube which passes vertically through an apex of a partition ceiling formed in a nebulization chamber of the aerosol generator. The sterilization chamber includes a sterilization container which houses the article to be sterilized. The container includes an aerosol inlet and an aerosol outlet in communication with an expansion cavity and nebulization cavity of the nebulization chamber via an aerosol inlet conduit and an aerosol outlet conduit respectively. The sterilizing agent is nebulized via the transducer and recirculated through the sterilization chamber.
