Ultrasonic atomization apparatus

摘要

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.

主权项

1. An atomization apparatus comprising: a container for holding a liquid to be atomized; a concave ultrasonic transducer operatively coupled to the container for transmission of acoustical energy to the liquid to be atomized at a focal zone to produce an acoustically active liquid; an electronic oscillator operatively coupled to the concave transducer to drive said transducer; a focal zone extender with a lower end disposed to be submerged below a surface of the liquid held in the container, the lower end having an inlet opening substantially at the focal zone, such that, in operation, a continuous column of the acoustically active liquid extends in non-atomized form throughout the full length of the focal zone extender so as to fill the focal zone extender; and an ultrasonic atomizing mesh disposed adjacent an upper end of the focal zone extender to contact at least part of the continuous column of acoustically active non-atomized liquid that exits the focal zone extender, whereby the atomizing mesh is vibrated, at ultrasonic frequency, principally by acoustical energy of the acoustically active non-atomized liquid such that the vibration of the atomizing mesh forces non-atomized liquid of the continuous column through the atomizing mesh so as to be emitted from a top surface of the atomizing mesh in atomized form.
