Abstract
【解決手段】液体エアロゾル形成基体のエアロゾル発生のための喫煙装置は、液体エアロゾル形成基体のための液体貯蔵部分16を備える装置ハウジング10を備える。装置はまた、霧化領域40を備える表面弾性波アトマイザー(SAWアトマイザー15)と、表面弾性波を発生してSAWアトマイザーの表面に沿って伝搬するための少なくとも一つの変換器20と、少なくとも第二の変換器と、液体エアロゾル形成基体を液体貯蔵部分16からSAWアトマイザー上の霧化領域に供給するために配置された供給要素30とを備える。
【選択図】図1
Description
エアロゾルの液滴サイズを説明するために当該技術分野において、いくつかの測定が使用される。これらは、質量中央径(MMD)および空気力学的質量中央径(MMAD)を含む。本明細書で使用される「質量中央径(MMD)」という用語は、半分の質量のエアロゾルが小径の液滴に含まれ、また半分の大径の液滴に含まれるような液滴の直径を意味するために使用される。本明細書で使用される「空気力学的質量中央径(MMAD)」という用語は、エアロゾルの中央質量の液滴と同一の空気力学的特性を有する単位密度の球の直径を意味するために使用される。
