PROBLEM TO BE SOLVED: To provide an atomizer of small size and low cost, allowing separate exchanging of an individual component having a mesh function, and capable of driving at a low power.SOLUTION: An atomizer 1 includes a radial vibrator 20 which has a flat annular profile and performs contraction vibration in a radial direction R at ultrasonic frequency, vertical vibration element 25 which is substantially plate-like and is fitted to the radial vibrator in such a manner as to stop a hole surrounded with an annular portion of the radial vibrator, to vibrate in a vertical direction Z being vertical to the vibration direction of the radial vibrator following vibration of the radial vibrator, and a mesh element 30 which has substantially a plate-like profile and is separated to face the vertical vibration element. The mesh element includes a plurality of through holes 31 that penetrate in a vertical direction. A liquid 8 present between the vertical vibration element and the mesh element passes the through hole following vibration of the vertical vibration element to cause atomizing.COPYRIGHT: (C)2014,JPO&INPIT【課題】メッシュ機能を持った構成要素単独での交換を可能にするとともに、低電力で駆動でき、小型且つ安価に構成可能な霧化装置を提供する。【解決手段】霧化装置1は、平坦な円環形状の外形形状をしていて、超音波周波数で径方向Rに伸縮振動する径方向振動子20と、実質的に板状であって、径方向振動子の円環部分で囲まれた孔を塞ぐように径方向振動子に取り付けられ、径方向振動子の振動に伴って径方向振動子の振動方向に対して垂直である縦方向Zに振動する縦方向振動要素25と、実質的に板状の外形形状をしていて、縦方向振動要素に対向して離間配置されるメッシュ要素30と、を備え、メッシュ要素は、縦方向に沿って貫通する貫通孔31を複数個有し、縦方向振動要素とメッシュ要素との間に存在する液体8が、縦方向振動要素の振動に伴って、貫通孔を通過することによって霧化する。【選択図】図3
