PROBLEM TO BE SOLVED: To provide a chemical volatilizing device capable of maintaining the effect of a sprayed chemical.SOLUTION: A cylindrical part 16 is installed between a suction hole 13 of a rear surface of a casing 11 and a delivery hole 15 of a front surface 14 of the casing 11. Air blowing means 21 is installed inside the rear surface 12, and air flow from the suction hole 13 side to the delivery hole 15 side is formed in the cylindrical part 16 by operating a fan motor 31 of the air blowing means 21. A chemical 2 in a chemical storage part 41 is supplied to spray means 44, so that the spray means 44 can intermittently spray the chemical 2. Wooden volatilization means 51 is fitted into a part, to which the chemical 2 is sprayed by the spray means 44, of the cylindrical part 16 so that the chemical 2 sprayed by the spray means 44 can be retained and volatilized. Volatilization means 51 is provided with a filter 61, and the filter 61 is arranged downstream of the spray means 44.COPYRIGHT: (C)2015,JPO&INPIT【課題】噴霧する薬剤の効果を維持することができる薬剤揮散装置を提供する。【解決手段】ケーシング11後面12の吸気穴13と前面14の送出穴15との間に筒部16を設ける。後面12の内側に送風手段21を設け、送風手段21のファンモータ31を作動することで、筒部16内に吸気穴13側から送出穴15側へ向けた空気の流れを形成する。薬剤貯留部41の薬剤2を噴霧手段44に供給し、噴霧手段44で薬剤2を間欠的に噴霧可能とする。噴霧手段44で薬剤2が噴霧される筒部16の部位に木製の揮散手段51を内嵌し、噴霧手段44より噴霧された薬剤2を保持しかつ、揮散できるように構成する。揮散手段51にフィルター61を設け、フィルター61を噴霧手段44の下流側に配置する。【選択図】図1
