Abstract:
1. A mist generator comprising: an ultrasonic transducer; an ultrasonic propagation medium (Liq an ultrasonic convergence and reflection mechanism provided in the ultrasonic propagation medium or the liquid for atomization; and means for discharging a mist outside, wherein the means for discharging the mist outside uses at least the ultrasonic convergence and reflection mechanism and an ultrasonic reflection tube as components, and the ultrasonic convergence and reflection mechanism has a function for pushing up the liquid for atomization (Liq wherein the ultrasonic reflection tube is composed of an ultrasonic reflecting material with tube length of 3 cm or more, the tube is kept at a predetermined height from a liquid level of the liquid for atomization so that a lower part of the tube may surround the end of the liquid and a local liquid dispersing portion, and air may enter from the lower part of the tube, and the tube has a mist/liquid separating function for introducing most of ultrasonic waves scattering around the dispersing portion into the tube to convert them into traveling waves in a tube axial direction, the tube carrying the mist by the traveling wave in the axial direction until it passes through the tube, and dropping a droplet liquid from the lower part of the tube.
