PROBLEM TO BE SOLVED: To provide a negative ion and nano mist generator for generating a large amount of anion and nano mist with a simple configuration.SOLUTION: The generator includes: a treatment chamber 14 for passing outer air with a blower 28 a water storage part 6 arranged in the lower part of the treatment chamber 14 a mortar shape rotary body 20 whose lower part is soaked into the water storage part 6 and where a diameter is enlarged toward the upper part and a cylindrical porous body 22 which is positioned in the outer periphery of the rotary body 20 and rotated together with the rotary body 20 and where water and air to be spattered by centrifugal force by the rotation are passable. An air guide cylinder 24 for guiding the outer air flowing-in from the upper part of the rotary body 20 to the outer periphery of the porous body 22 is arranged at interval in the outer periphery of the rotary body 22 and has an oval shape where a pair of large flow passages and a pair of small flow passages 26, 26 are formed with the porous body 22. Consequently, a pressure difference is generated in the air flows so as to make a turbulance, and then, a large amount of negative ion and nano mist are generated.COPYRIGHT: (C)2010,JPO&INPIT【課題】簡単な構成で大量のマイナスイオンとナノミストを発生させることが出来るマイナスイオン及びナノミスト発生装置を提供する。【解決手段】送風機28により外気が通過する処理室14と、該処理室14の下部に設けられた貯水部6と、この貯水部6に下部を水没させ上方に向かって径が拡大する擂り鉢状の回転体20と、この回転体20の外周に位置し、該回転体20と共に回転しこの回転による遠心力で飛散される水及び空気が通過可能な円筒状の多孔体22とを備えたもので、前記多孔体22の外周には間隔を置いて、回転体20の上方から流入する外気を多孔体22の外周に案内する空気案内筒24を設けると共に、該空気案内筒24は楕円形状で多孔体22との間には一対の大流通路と一対の小流通路26、26とを形成したことで、空気流に圧力差が生じて乱流となり、大量のマイナスイオンとナノミストを発生出来るものである。【選択図】図2
