A detachable draining device capable of movably assembling with a bottle wall is disclosed in the present invention. The detachable draining device includes a tube, a bridging component and a flow controller. A first opening and a second opening are respectively formed on two ends of the tube. The bridging component is disposed on one end of the tube, and detachably passed through the bottle wall. The bridging component is a hollow structure for connecting to the first opening on the tube. The flow controller is disposed on the other end of the tube opposite to the bridging component. The flow controller is connected to the second opening on the tube, to control flow rate of the tube according to open/close modes of the flow controller.本創作揭露一種可拆卸式排水裝置,用來活動地組裝在一瓶壁上。該可拆卸式排水裝置包含有一管件、一橋接件以及一流量控制器。該管件之兩端分別具有一第一開口與一第二開口。該橋接件設置於該管件之一端,並以可拆卸方式穿設該瓶壁。該橋接件為一中空結構,且該中空結構連通該管件之該第一開口。該流量控制器設置於該管件相對該橋接件之另一端。該流量控制器連通該管件之該第二開口,以利用該流量控制器之開關狀態控制流經該管件之流體流量。10‧‧‧可拆卸式排水裝置12‧‧‧管件125‧‧‧螺紋結構14‧‧‧橋接件16‧‧‧流量控制器18‧‧‧第一防水墊片20‧‧‧第二防水墊片22‧‧‧固定件24‧‧‧瓶壁
