Abstract
An ultrasonic atomizer is provided including an ultrasonic vibrator, a reservoir, and a heat exchanger. The ultrasonic vibrator is connected to an amplifying section. The amplifying section has an exterior surface and a tip thereon. The amplifying section can be elongated and the amplifying section can be inclined at an angle that is preferably between about 5.degree. to 10.degree. from horizontal. The reservoir is in fluid communication with the exterior surface of the amplifying section. The reservoir contains a liquid. A pump can be located between the reservoir and the exterior surface of the amplifying section in order to assure a liquid flow rate of between about 10 to about 30 ml/min. The heat exchanger is provided in order to control the temperature and viscosity of the liquid. The liquid is directed to flow from the reservoir and over the exterior surface of the amplifying section to the tip. A feed tube having a dispensing end can be provided. The feed tube is located between the reservoir and the exterior surface of the amplifying section in order for the liquid to be dispensed from the dispensing end onto the exterior surface. Preferably, the feed tube passes through th…
