  • Patent number: 7891580
    Abstract: A high volume piezoelectric atomizer for use with common consumer spray products is disclosed. The piezoelectric atomizer may include an actuator, a substrate and a supply of a liquid product to be dispensed. The substrate may include a plurality of tapered perforations in direct contact with the supply of a liquid product. A control circuit vibrates the actuator, substrate and its tapered perforations against the supply at velocities of at least 500 mm/s. Droplets are dispensed at a delivery rate of approximately 0.2 g/s resulting in plumes of at least 2 feet in length resulting in a Valpey factor of at least 51.0.
    Type: Grant
    Filed: April 30, 2008
    Date of Patent: February 22, 2011
    Assignee: S.C. Johnson & Son, Inc.
