<p>PROBLEM TO BE SOLVED: To provide an ultrasonic atomizer which has better liquid atomization performance, and which is more compact and is capable of efficiently atomizing liquid with less power consumption.SOLUTION: The present invention is an ultrasonic atomizer that applies ultrasonic vibration to liquid in a container 1, thereby forming a liquid ridge part and/or a spray part on a liquid surface and atomizing the liquid. The ultrasonic atomizer is characterized in that a recessed part 2 is provided in the bottom part of the container 1, an ultrasonic vibrator 3 is arranged in the base of the recessed part 2, a metal washer-shaped member 4 having an aperture or a container base plate having an aperture at the center of the recessed part 2 is arranged covering the recessed part 2, and a porous plate 6 in which numerous minute through-holes are formed and arrangement means for arranging the porous plate 6 in a prescribed position are provided, in which the porous plate 6 is attached to the arrangement means via an elastic retaining member 7, and, by this arrangement means the porous plate 6 is arranged in a position such that the lower surface of the porous plate 6 makes contact with the liquid ridge part and/or the spray part formed when the ultrasonic vibration is occurring.</p> |
