PROBLEM TO BE SOLVED: To provide a mist generator prevented from being mistakenly used as a facial treatment device while operated with a strong air volume.SOLUTION: This generator is provided with an air volume setting means 46 which sets the blowing volume of air emitted from a blowout port 28 and containing nanomist and negative ions. When the device is operated with the strong air volume set by the air volume setting means 46 in a mist operation, according to the result of detection by a human body sensor 41, the air volume of a blowing machine 4 is changed to a weak air volume or an air volume weaker than the strong air volume by a control means 42 when the presence of a person is detected in a prescribed region, and the air volume of the blowing machine 4 is automatically put back to the strong air volume by the control means 42 when the presence of the person is out in the prescribed region.COPYRIGHT: (C)2013,JPO&INPIT【課題】誤って強風量のまま美顔器として使用することを防止するミスト発生装置を提供する。【解決手段】吹出口28から放出されるナノミスト及び負イオンを含んだ空気の送風量を設定する風量設定手段46を設け、ミスト運転の際に風量設定手段46にて、強風量で運転した時には、前記人体センサ41の検出結果が所定範囲に人の存在を検知した場合には、制御手段42にて送風機4の風量を弱風量または強風量よりも小さい風量に変化し、前記所定範囲に人の存在が無くなった場合には、制御手段42にて送風機4の風量を強風量に自動で戻すようにしたものである。【選択図】 図2
