Ultrasonic device for atomizing liquids

摘要

An ultrasonic device for atomizing liquids has at least one atomization unit wherein an upward directed ultrasonic transducer is located at the bottom of the unit with the top of the unit being open. A reservoir is connected to the unit and a minimum liquid level is maintained in each unit during atomization. An electric supply is connected to the transducer and liquid is circulated from the reservoir, across each transducer, and back to the reservoir for removal of impurities.
