PROBLEM TO BE SOLVED: To provide an electrostatic atomizing device which enables an introduction tube to be connected to a target section in a simple manner without causing positional deviation and highly efficiently supplies electrically charged water particles through the introduction tube to the target section.SOLUTION: The electrostatic atomization device includes an ejection port 10 that ejects electrically charged water particles and the introduction tube 11 having the upstream end thereof connected to the ejection port 10, wherein the introduction tube 11 has, in the middle of the flow path thereof, a bellows structure 14 in which small-diameter parts 12 and large-diameter parts 13 are arranged contiguously in an alternating manner. The bellows structure 14 is formed in such a manner that the inner diameters r2a, r2b, r2c of the respective small-diameter parts 12 become sequentially larger the more downstream of the introduction tube the small-diameter parts 12 are located. Thus, the introduction tube 11 can be connected easily to the target section through the effective use of the bellows structure 14, and also, the flow of air inside the introduction tube 11 is less likely to be disturbed.COPYRIGHT: (C)2012,JPO&INPIT【課題】目的箇所にまで導入管を位置ずれなく簡単に接続させることができ、且つ、この導入管を通じて帯電微粒子水を目的箇所にまで高効率で供給することのできる静電霧化装置を提供する。【解決手段】帯電微粒子水を放出する放出口10と、放出口10に上流端が接続された導入管11とを備えた静電霧化装置において、導入管11は、小径部分12と大径部分13とが交互に連続する蛇腹構造14をその流路途中に有し、蛇腹構造14が有する複数の小径部分12の内径r2a,r2b,r2cを、下流側に位置する小径部分12ほど順に大きくなるように設けたものとする。これにより、蛇腹構造14を有効活用して、導入管11を目的箇所に簡単に接続させることができ、しかも、この導入管11中の空気の流れには乱れが生じ難くなる。【選択図】図1
