This creation is that related what is a kind of " tooth flusher structural improvement ",It is by one first cylinder,One bottom cover,One second cylinder,One or more jet pipe and a hose group are formed； First cylinder lateral margin has one to engrave hole,And its outer peripheral edge hole site Wei Yulou has one first bulge loop,And the first cylinder inner edge surface is equipped with one or more spacing block set,And the side mounting that is pivoted of bottom cover,And bottom cover installs the first cylinder of what bottom surface,So that side seal piece is pivoted sealing what and engrave hole,And the second cylinder apical margin has a perforation being connected to inside,And it is respectively equipped on one support block and once support block with respect to the spacing block set lateral margin of the first cylinder of what,The perforation of another nozzle-end installing the second cylinder of what,Hose system by a hose,The cock body of one elastic element and a several open-works of tool is formed,The second cylinder of what bottom surface is installed in hose one end,Hose another end installs cock body； Thereby,Not only there is preferably sliding extension locating effect,Portable is facilitated to store,And the leakproofness of entirety it is good,It is water-tight.本創作係有關於一種「沖牙器結構改良」，其係由一第一筒體、一底蓋、一第二筒體、一以上之噴管及一軟管組所組成；第一筒體側緣具有一鏤孔，且其外周緣位於鏤孔位置具有一第一凸環，而第一筒體內緣面設有一以上之限位凸塊，而底蓋之樞設一側封片，且底蓋裝設於第一筒體底面，使側封片樞轉密封於鏤孔，而第二筒體頂緣具有一與內部連通之穿孔，且其相對於第一筒體之限位凸塊側緣分別設有一上抵塊及一下抵塊，另噴管端部裝設於第二筒體之穿孔，軟管組係由一軟管、一彈性元件及一具若干透孔之塞體所組成，軟管一端裝設於第二筒體底面，軟管另端裝設塞體；藉此，不僅具有較佳之滑動伸縮定位效果，方便攜行儲放，且整體之密封性佳、不漏水。
