PROBLEM TO BE SOLVED: To provide a vacuum-type water supply device which makes a vacuum and a water faucet fully opened or almost fully opened for watering plants (for example, plants in a flowerpot), thereby making the watering time significantly reduced compared with conventional water supply devices in which generally the water faucet is opened a little (to a degree at which the water pressure is not applied) for watering.SOLUTION: A vacuum-type water supply device comprises: a water passage pipe which is used as a handle and is of 13φ and approximately 1 m in length, one end of the water passage pipe being connected to a hose for feeding pressurized water from a water source a deformed water passage socket of 40φ×13φ connected to the other end of the water passage pipe and a perforated plate inserted into the deformed socket of 40φ. The water flows from the pressurized pipe of 13φ and passes through the perforated plate, where the water is depressurized and forms a vacuum. The vacuum-type water supply device uses the effect to allow the water faucet to be fully opened or almost fully opened for watering plants.COPYRIGHT: (C)2014,JPO&INPIT【課題】植物に灌水するとき(植木鉢などに)一般では蛇口を少し開栓して(水圧がかからない程度)ホース口より灌水していたものを真空式灌水器にて真空にして蛇口の水量を全開又はこれに近い状態で灌水して灌水時間を大幅に短縮する器具を提供する。【解決手段】柄13φの水通パイプ1m位に水源からの圧力水のホースを一方に接続し他方に40φ×13φの水通用の異形ソケットを接続この40φのパイプに40φの目皿を挿入したものである。13φの圧力水の方より通水この目皿を通過後に真空無圧になるこれを利用して蛇口全開又はこれに近い状態の水量で灌水する。【選択図】図1
