US Patent 7954730 Piezoelectric fluid atomizer apparatuses and methods

Piezo aerosol and ultrasonic atomizer apparatuses are disclosed. In some embodiments, a piezo aerosol apparatus may comprise a piezo component defining an opening bonded to a metal plate defining a mist reservoir. The mist reservoir may define a plurality of apertures (or holes) orientated substantially perpendicular, and the opening of the piezo component may be located above the mist reservoir. The piezo aerosol apparatus generally defines a non-symmetric compound, while the ultrasonic atomizer comprises a piezo component and metal plate of substantially the same diameter in length. Other embodiments are also claimed and disclosed.
