Abstract

The present invention is directed to the combination of a vibrating element and an ultrasonic nozzle having an ultrasonic vibrator. The combination includes a body having a liquid supply passage therethrough and a chamber having a first and second end. The liquid supply passage is in communication with the chamber via its first end. The second end of the chamber defines an opening. An inner peripheral wall forms a portion of the chamber intermediate the first and second end. A multistepped edged portion is formed on the inner peripheral wall and each step defines an edge which severs and atomizes the liquid which cascades thereover from the liquid passage.

Dependent claims

The vibrating element in combination with an ultrasonic nozzle typically having an ultrasonic vibrating means comprises:

a body having a liquid supply passage means therethrough and a chamber having a first and second end;
said liquid supply means being in communication with said chamber via said first end, said liquid supply passage means adapted for passing liquid into said chamber;
said second end defining an opening;
an inner peripheral wall forming a portion of said chamber intermediate said first and second end;
a multi-stepped edge portion being formed on said inner peripheral wall, each step of said multi-stepped edge portion defining an edge, each said edge being adapted to sever and atomize said liquid;
whereby liquid supplied via said passage means cascades over said edges and is atomized from said edges when said body is driven by the ultrasonic vibrating means.
