The present invention high cleaning function to provide a watering system easy to use ozone water can watering ozone water anywhere in the state holding the deodorization function and sterilizing function. A dissolved ozone in tap water with an ozone water generator to generate ozone water or ozone concentration 2.5ppm, a container 2 for containing the ozone water having a predetermined volume which is generated by an ozone water generator , and a pump 3 connected to the container 2, the container and the pump is held in a freely carrier 6 runs, the carrier is moved to any location in a state of being injection ozone water in a vessel and connected to a pump It was constructed to allow watering the ozone water in the container by hand-held spray gun 5 of that hose tip. .BACKGROUND 2【課題】高い洗浄機能、脱臭機能や殺菌機能を保持した状態でオゾン水を任意の場所に散水することができる使い勝手のよいオゾン水の散水システムを提供する。【解決手段】水道水にオゾンを溶解させて2.5ppm以上のオゾン濃度のオゾン水を生成するオゾン水生成器と、オゾン水生成器で生成された所定体積のオゾン水を収容する容器2と、容器2に接続されるポンプ3とを有し、容器とポンプとが走行自在なキャリア6で保持され、容器にオゾン水を注水した状態でキャリアを任意の場所に移動し、ポンプに接続されるホース先端の手持式スプレーガン5により容器内のオゾン水を散水できるように構成した。【選択図】図2
