Abstract
【解決手段】圧電体を有する超音波振動子12により、この超音波振動子12の超音波ホーン13の先端面13aに供給された液体を霧化する、超音波噴霧器11に取付けて用いる超音波霧化機10であって、超音波振動子12と、この超音波振動子12の前部超音波ホーン(超音波ホーン)13の先端面13aに配置されて供給された液体を保持する吸液性の緩衝体14と、緩衝体14の外側に重ねて配置されるメッシュ構造を有する多孔板15とを含み、且つ超音波振動子12による振動方向Xと、多孔板15のメッシュ構造の孔軸方向とが一致している。

Description
また不織布の表面粗さの平均偏差SMDが低いと液滴の粒径が細かくなる傾向にあり、本願発明の課題を解決する為には好適となる。
繊維の種類としては前記のコットンの他、テンセル(登録商標)等の精製セルロース繊維が、不織布とした場合の表面粗さの平均偏差SMDをより低くでき、液滴の粒径も細かくすることができる観点で好ましい。
超音波振動子12によって液体が霧化されて生じた液滴の粒径と、多孔板15のメッシュ構造の孔径との比(粒径)/(孔径)は、液体の粘度、超音波振動子12の周波数、振幅、多孔板15の材質等を適宜変更することによって調整することができる。
ここで、メッシュ構造の孔径(目開き量)とは、メッシュ構造を構成している線と線の間の空間の大きさをいい、下式で定義することができる。
孔径(目開き量)=25.4mm÷メッシュ数−線径
ここで略一致とは、孔軸に対して例えば15度〜−15度程度の範囲をいう。かかる範囲であれば、本願発明の効果を得ることができる。
また、霧化される液体の粘度によっては、吸液性の緩衝体とともに小型のチューブポンプやダイアフラムポンプを併用して、液体供給量をコントロールし、定量を吸液性の緩衝体に滴下供給することも可能である。
また、送風ファン18からの風は必ずしも必要ではなく、送風ファン18を停止すれば、より柔らかい霧を噴霧することができる。
