PROBLEM TO BE SOLVED: To provide a blowing-type chemical agent diffusive apparatus enabling a chemical agent to be uniformly diffused throughout the room by placement of it in the room.SOLUTION: The blowing-type chemical agent diffusive apparatus is configured such that, the apparatus body 1 is installed with a chemical agent holder 4, a fan 5 and a motor 6 the motor 6 is put to normal and reverse rotary drive alternately to make normal and reverse rotations of the fan 5 alternately, thus diffusing a chemical agent alternately via a first flow-through port 2 formed on the top face 1a of the apparatus body 1 and a second flow-through port 3 formed on the flank 1b of the apparatus body 1 to uniformly diffuse it throughout the room.COPYRIGHT: (C)2010,JPO&INPIT【課題】室内に置いて使用することで薬剤を室内全域に均一に放散できる送風式薬剤放散装置とする。【解決手段】装置本体1に、薬剤保持体4と送風ファン5とモータ6を設け、そのモータ6を交互に正回転駆動、逆回転駆動して送風ファン5を交互に正回転、逆回転して、装置本体1の上面1aに形成した第1流通口2と装置本体1の側面1bに形成した第2流通口3から交互に薬剤を放散して室内全域に均一に薬剤を放散する。【選択図】図2
