PROBLEM TO BE SOLVED: To provide a mist blower, capable of surely switching between opening and closing of a passage for a chemical by simple operation.SOLUTION: A ventilation pipe 60 is provided with a handle 62 held by a user in use, and an operation button 83 operable by pressing is provided in the vicinity of the handle 62. At every pressing of the operation button 83, opening and closing of a passage opening and closing valve 80 is switched. Thus, a communicating hole 81d is surely switched to the open or close state by the simple and same pressing operation for the operation button 83, so that the opportunity to carelessly touch the operation button 83 by users hands and body is decreased, whereby the disadvantage that the communicating hole 81d is opened without being noticed by the user to release the chemical can be prevented.COPYRIGHT: (C)2013,JPO&INPIT【課題】簡単な操作によって確実に薬液の流路の開閉を切換えることのできるミストブロワを提供する。【解決手段】送風管60には、使用者が使用時に把持するハンドル62が設けられ、ハンドル62の近傍には、押下操作可能な操作ボタン83が設けられ、操作ボタン83の押下操作毎に流路開閉弁80の開閉が切換えられる。これにより、簡単な操作ボタン83の同じ押下操作によって確実に連通孔81dが開放または閉鎖された状態に切り換わるので、使用者の手や体が不用意に操作ボタン83に接触する機会が減り、使用者が気付かずに連通孔81dが開放されて薬液が放出されるという不都合が生じることを防止できる。【選択図】図1
