PROBLEM TO BE SOLVED: To achieve the spray and diffusion of hyperfine particles while achieving the aid of the rising-up of fine water droplets and reverse flow avoidance utilizing a simple air flow generation means.SOLUTION: In a hyperfine particle diffusion device, a motor is driven, and, in accordance with the rotation of a motor rotary shaft, a rotor and a fan are rotated, and the first rising air flow is generated in a square enclosure and an inner enclosure. Further, in a state where the rotor is rotated, liquid is dropt from the tip part of a hose toward the surface of the rotor, is collide against the surface of the rotor and is thereafter made into fine particles by the centrifugal force in accordance with the rotation of the rotor, and the fine particles are diffused to the outside. The fine particles diffused to the outside are collide against a tilted projection in a collision plate and are made into hyperfine particles, and the hyperfine particles are lifted by the second rising air flow generated at the inner enclosure, and are subsequently sprayed and diffused to the outside air.COPYRIGHT: (C)2016,JPO&INPIT【課題】 簡易な、気流発生手段を利用して、微細な水滴の競り上がり助成と、逆流回避を図りつつ、超微粒子の噴霧と拡散とを図ることを可能とする。【解決手段】超微粒子拡散装置において、モータが駆動し、モータ回転軸の回転に伴って、回転体及びファンが回転し、方形筐体、及び内筐体には第1上昇気流が発生する。更に、回転体が回転した状態で、ホースの先端部から回転体の表面に向けて流体を滴下し、回転体の表面に衝突した後、回転体の回転に伴う遠心力によって微粒子とし、外側に拡散する。外側に拡散した微粒子は、衝突板内の傾斜突条に衝突し、超微粒子となって、内筐体に発生する第2上昇気流により上昇した後、外気中に、噴霧、かつ拡散される。【選択図】図2
