PROBLEM TO BE SOLVED: To provide an oral cavity washer in which the usage direction is hardly limited, a washing liquid can be jetted effectively and the washing liquid hardly remains in a liquid storage part.SOLUTION: An oral cavity washer includes: a liquid storage part for storing a liquid for washing an oral cavity a liquid supply mechanism for sending out the liquid from the liquid storage part to the oral cavity and a guide mechanism for guiding the liquid flowing from the liquid storage part to the liquid supply mechanism. The guide mechanism includes: a first inflow part in which a first inflow port where the liquid flows in is formed and a second inflow part in which a second inflow port where the liquid flows in is formed. When the liquid storage part is below the liquid supply mechanism, the second inflow port is located below the first inflow port.COPYRIGHT: (C)2014,JPO&INPIT【課題】使用する向きが制限されにくく、洗浄液を有効に噴射でき、貯液部に洗浄液が残存しにくい口腔洗浄器を提供すること。【解決手段】口腔内を洗浄するための液体を溜める貯液部と、該貯液部から前記口腔内へ前記液体を送り出す給液機構と、前記貯液部から前記給液機構へ流れる前記液体を案内する案内機構と、を備え、前記案内機構は、前記液体が流入する第1流入口が形成された第1流入部と、前記液体が流入する第2流入口が形成された第2流入部と、を含み、前記貯液部が前記給液機構の下方にあるとき、前記第2流入口は、前記第1流入口より下方に位置することを特徴とする口腔洗浄器。【選択図】図1
