Claim 0:
1. A mist generator device comprising:
a mist generator housing which is elongate and comprises an air inlet port and a mist outlet port;
a liquid chamber provided within the mist generator housing, the liquid chamber containing a liquid to be atomized;
a sonication chamber provided within the mist generator housing;
a capillary element extending between the liquid chamber and the sonication chamber, the capillary element having a leading end, an opposite trailing end, and a central longitudinal axis passing through the ends, the capillary element is generally planar with a first portion having a generally rectangular shape which terminates at the leading end in a second portion having a partly circular shape with a diameter, the first portion terminates at the trailing end to form an enlarged end having a width, each of the diameter of the second portion and the width of the enlarged end, respectively, being greater than a maximum width of the first portion transverse to the central longitudinal axis of the capillary element, the enlarged end of the capillary element is within the liquid chamber and the second portion of the capillary element is within the sonication chamber;
an ultrasonic transducer having a generally planar atomization surface which is provided within the sonication chamber, the ultrasonic transducer being mounted within the mist generator housing, wherein at least part of the partly circular-shaped second portion of the capillary element is superimposed on at least a part of the atomization surface, and wherein the ultrasonic transducer is configured to vibrate the atomization surface to atomize the liquid carried by the second portion of the capillary element to generate a mist comprising the atomized liquid and air within the sonication chamber; and
an airflow arrangement within the mist generator housing which provides an air flow path between the air inlet port, the sonication chamber and the mist outlet port, wherein the airflow arrangement is configured to guide a direction of a flow of air along the airflow path such that the flow of air is substantially perpendicular to the atomization surface of the ultrasonic transducer as the flow of air passes into the sonication chamber.
