PROBLEM TO BE SOLVED: To provide a stationary quantitative atomizer which atomizes various active ingredients for aroma, odor elimination, insect killing, insect proof and the like, can avoid excessive atomization without requiring complicated operation, is excellent in safety and usability, and is suitably used in a small space, and a method for spraying a chemical liquid to small space using the atomizer.SOLUTION: A quantitative atomization type pump which enables a fixed amount of atomization by one operation is used as an atomization means to avoid a risk of excessive atomization, and an atomization direction is controlled to be more upward than a horizontal direction, thereby enabling to provide a highly convenient atomizer which allows sufficient exhibition of the effects of a chemical liquid and causes no safety problem, and a method for spraying a chemical liquid using the atomizer.COPYRIGHT: (C)2013,JPO&INPIT【課題】芳香、消臭、殺虫、防虫等の各種有効成分を噴霧する噴霧装置であって、複雑な操作を要することなしに、過剰な噴霧を避けることができ、安全性と使い勝手に優れる、小空間での使用に適した据え置き型定量噴霧装置、及びこれを用いた小空間への薬液散布方法を提供する。【課題の解決手段】噴霧手段として、一動作で一定量の噴霧が可能な定量噴霧型ポンプを用いることにより、過剰噴霧の危険性を避け、さらには噴霧の方向を水平方向より上向きに制御する工夫によって、薬液の効果が充分に発揮され、安全性の問題を生じない利便性の高い噴霧装置、及びこれを用いた薬液散布方法の提供が可能となる。【選択図】図5
