PROBLEM TO BE SOLVED: To provide an efficient extermination device that, in order to prevent waste, sprays against noxious animals like rats only when they are detected by an infrared sensor while conventionally spraying is often wasted because it is done prophylactically at the point of time when appearance of noxious animals like rats is indefinite.SOLUTION: The extermination device for noxious animals like rats is characterized in that it has an infrared sensor interlocking system in which, for the purpose of eliminating waste of a conventional spray method for exterminating noxious animals like rats, when rats or the like appear in the range of a fixed view angle, the movement is detected by an infrared sensor. Then, the detection signal is amplified by an amplifier circuit (operational amplifier) and transmitted to a control circuit (timer circuit). Further, it actuates an electromagnet through an electric solenoid, pulling down a spray pushing lever by the force of the electromagnet, and spraying by pressing a spray pushing button.COPYRIGHT: (C)2014,JPO&INPIT【課題】ネズミ等害獣が出るか出ないか判らない時点で、予防的にスプレーするのでムダが多かった。そのムダをなくすため、ネズミ等害獣を赤外線センサーで検出したときだけスプレーする、ムダのない駆除装置を提供する。【解決手段】ネズミ等害獣を駆除する従来のスプレー法のムダを解決するため、一定の視野角の範囲内にネズミ等が現われたとき、その動きを赤外線センサーが検知し、その検出信号を増幅回路(オペアンプ)で増幅、制御回路(タイマー回路)に送り、更にソレノイドを通じて電磁石を作動、電磁石の力でスプレー押しレバーを引き下げ、スプレー押しボタンを押してスプレーする、赤外線センサー連動方式のネズミ等駆除装置であることを特徴とする。【選択図】図1
