Mist generator and mist emission rendering apparatus
First Claim
1. A mist generator comprising:
- an ultrasonic transducer;
an ultrasonic propagation medium (Liq1) or a liquid for atomization (Liq2) provided so as to fill a plane of vibration of the ultrasonic transducer;
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 (Liq2) to locally disperse an end thereof, andwherein 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.

Abstract
An apparatus includes an ultrasonic transducer; an ultrasonic propagation medium disposed so as to fill a plane of vibration of the transducer; liquid retaining means disposed so as to be in contact with an end face of the medium; and an ultrasonic focusing reflecting mechanism disposed in an ultrasonic propagation path, thereby the apparatus attains discharging into air and atomization of the liquid by use of ultrasonic waves. Atomization efficiency is enhanced by the use of an ultrasonic reflection tube, and mist emission is carried out. Use is made of a compact liquid container equipped at its bottom with an ultrasonic transmission membrane. Various types of liquids can be atomized by changing the direction of ultrasonic course.
