Abstract:
1. An apparatus for ultrasonically atomizing a liquid, the apparatus comprising: an atomization chamber for storing the liquid; a first ultrasonic oscillator for ultrasonically oscillating the liquid and generating a first liquid column that projects in a projecting direction from a surface of the liquid to atomize the liquid into mist; an amplifier for ultrasound connected to the first ultrasonic oscillator to supply high-frequency power thereto for ultrasonic oscillation; and a streaming mechanism for conveying a carrier gas in the atomization chamber, the streaming mechanism including a suction mechanism, wherein the suction mechanism has a first suction port located inside the atomization chamber for sucking the carrier gas into the first suction port, and the suction mechanism is elongated and extends into the atomization chamber inwardly, wherein the first suction port of the suction mechanism is arranged in the atomization chamber at a distance away from a center axis of the first liquid column in a horizontal direction perpendicular to the projecting direction of the first liquid column, and an opening of the first suction port will face a side surface of the first liquid column which extends upwardly from the surface of the liquid, wherein the suction mechanism is arranged to suck the carrier gas from the side surface of the first liquid column, which extends upwardly from the surface of the liquid, in a horizontal direction perpendicular to the projecting direction of the first liquid column such that the carrier gas flows across the first liquid column and the mist from the first liquid column is separated and discharged outwardly of the atomization chamber, wherein the streaming mechanism comprises a blast mechanism provided with a first blower port for blowing the carrier gas against the first liquid column generated, wherein the blast mechanism is elongated and extends into the atomization chamber inwardly, wherein the first suction port and the first blower port are located at substantially the same level away from the first ultrasonic oscillator in the projecting direction of the liquid column, and wherein the first suction port and the first blower port are positioned on opposite sides with respect to the first liquid column in the horizontal direction perpendicular to the projecting direction of the liquid column, facing each other within a projecting region of the liquid column in the projecting direction of the liquid column.
