< Topic >You send from the pump and through the hose, you retrench the amount used of the liquid medicine without decreasing the pressure of the liquid medicine which is sent to the nozzle, to small diameter convert the said feed hose, you offer the power sprayer which it tries to improve the operativity of labor assistant worker.SolutionsThe liquid medicine tank with 1 and pump 3, through tail pipe 5, in the power sprayer where it concatenates, sends with the said pump and nozzle 7 and through hose 9, concatenating, becomes, in the said tail pipe the power sprayer which features that air injection means 41 in order to inject the air to the liquid medicine of the said sucking inside of pipe are made to have.< Choice figure >Drawing 1【課題】ポンプから送りホースを介してノズルに送られる薬液の圧力を低下させることなく、薬液の使用量を節減し、該送りホースを小径化し、作業者の手元の操作性を向上させるようにした動力噴霧機を提供する。【解決手段】薬液タンク1とポンプ3とを吸込み管5を介して連結し、該ポンプとノズル7とを送りホース9を介して連結してなる動力噴霧機において、該吸込み管には該吸込み管内の薬液に空気を注入するための空気注入手段41を備えさせたことを特徴とする動力噴霧機。【選択図】図1
