PROBLEM TO BE SOLVED: To provide a fan type chemical diffusing apparatus that sufficiently treats two damaged spaces with a chemical.SOLUTION: The fan type chemical diffusing apparatus has a constitution that an apparatus body 1 having a first ventilation port 6 and a second ventilation port 7 directed in different directions is equipped with a chemical holder 2, a fan 3, a motor 4 and a motor drive control means 5, while a chemical is diffused from the first ventilation port 6 or the second ventilation port 7 by forwardly and reversely rotating and driving the motor 4 so as to forwardly and reversely rotate the fan 3 and the amount of a chemical diffused from the first ventilation port 6 and the second ventilation port 7 is increased or decreased and regulated by arbitrarily setting the forward rotation drive time rotation drive time and the reverse rotation drive time of the motor 4.COPYRIGHT: (C)2010,JPO&INPIT【課題】2つの被害空間を十分に薬剤処理できる送風式薬剤放散装置とする。【解決手段】異なる方向に向かう第1流通口6と第2流通口7を有した装置本体1に、薬剤保持体2、送風ファン3、モータ4、モータ駆動制御手段5を設け、そのモータ4を正逆回転駆動して送風ファン3を正逆回転することで第1流通口6又は第2流通口7から薬剤を放散するようにすると共に、そのモータ4の正回転駆動時間と逆回転駆動時間を任意に設定して第1流通口6、第2流通口7から放散する薬剤の量を増減調整できるようにした送風式薬剤放散装置。【選択図】図2
