Abstract

The present invention relates to an ultrasound liquid atomization and/or separation system including an ultrasound atomizer and a liquid storage area in communication with the ultrasound atomizer. The ultrasound atomizer has an ultrasound transducer, an ultrasound tip at the distal end of the transducer, a liquid delivery orifice or plurality of liquid delivery orifices, and a radiation surface at the distal end of the tip. The atomizer may include a liquid delivery collar having a liquid receiving orifice and a liquid delivery orifice. The liquid delivery collar may also include a central orifice into which the ultrasound tip may be inserted.

Claims

1. An ultrasound atomizer comprising:

a. an ultrasound transducer;

b. an ultrasound tip having a radial surface between a distal end and a proximal end;

c. a radiation surface at the ultrasound tip distal end;

d. the ultrasound tip proximal end fastened to the ultrasound transducer;

e. a delivery collar having a delivery collar distal end, a liquid receiving orifice and a liquid delivery orifice in fluid communication with the liquid receiving orifice and sufficiently narrow to atomize an exiting pressurized liquid;

f. the liquid delivery orifice positioned at a distance from the tip such that said pressurized liquid exiting the liquid delivery orifice as an expanding drop contacts the ultrasound tip before the surface tension of the liquid is broken by the expansion of the drop to permit forming from the drop a liquid conduit between the delivery collar and the ultrasound tip.

2. The ultrasound atomizer of claim 1 having a groove within the radial surface.

3. The ultrasound atomizer of claim 1 wherein the liquid delivery orifice is positioned to deliver the drop near the antinode position of an ultrasound wave passing through the tip.

4. The ultrasound atomizer of claim 1 wherein the delivery collar encircles the ultrasound tip.

5. The ultrasound atomizer of claim 1 wherein delivery collar does not contact the ultrasound tip.

6. The ultrasound atomizer of claim 1 further comprising a convex portion within the radiation surface.

7. The ultrasound atomizer of claim 1 further comprising a concave portion within the radiation surface.

8. The ultrasound atomizer of claim 1 further comprising a flat portion within the radiation surface.

9. The ultrasound atomizer of claim 1 further comprising a tapered portion within the radiation surface.

10. The ultrasound atomizer of claim 1 further comprising a conical portion within the radiation surface.
