PROBLEM TO BE SOLVED: To provide a spray device capable of easily changing a spray amount without using a flow rate control valve.SOLUTION: Provided is a spray device 1 comprising: a solution tank 10 of storing an antiseptic solution and the other spray liquid L; a spray nozzle 20 of mixing the spray liquid L fed from the solution tank 10 with a pressurization air A so as to be sprayed; an air pump 30 of generating the pressurization air A to be fed to the spray nozzle 20 by the rotational driving of a motor 31; a storage amount sensor 40 of measuring the storage amount of the storage liquid l in the solution tank 10; and a control part 61 of controlling the revolution speed of the motor in the air pump 30 based on the measured result output from the storage amount sensor 40 in order to suppress a change in atomization amount due to a water head difference h of the spray liquid L between the spray nozzle 20 and the solution tank 10.SELECTED DRAWING: Figure 1 【課題】流量調整バルブを用いることなく噴霧量を容易に変化させることを可能にする噴霧装置の提供。【解決手段】消毒液その他の噴霧液Ｌを貯留する溶液タンク１０と、溶液タンク１０から供給された噴霧液Ｌを加圧エアーＡと混合して噴霧させる噴霧ノズル２０と、モータ３１の回転駆動により噴霧ノズル２０に供給すべき加圧エアーＡを生成するエアーポンプ３０と、溶液タンク１０内の噴霧液Ｌの貯留量を計測する貯留量センサ４０と、噴霧ノズル２０と溶液タンク１０内の噴霧液Ｌとの間の水頭差ｈに伴う噴霧量の変化を抑えるために、貯留量センサ４０から出力された計測結果に基づいてエアーポンプ３０のモータ回転数を制御する制御部６１とを備える噴霧装置１。【選択図】図１
