An outfall valve structure conforming to ergonomics is primarily composed of a casing, which is moveably connected with a hollow pipe. The casing is in the form of a short pipe, the exterior wall thereof is provided with a coupler with an opening provided on the bottom such that the casing would become a tee; whereas the interior wall thereof is provided with a circle of hollow flow path along the position where the opening is. The hollow pipe is provided with a hook at one end of its pipe wall, and with a coupler at the other end. A barrier edge and an opening are provided between the hood and the coupler, such that the hollow pipe can be inserted into the casing with the end having a hook, thereby the casing can slidably move on the hollow pipe without detaching from the hollow pipe since it is stopped by the barrier edge and the hook. Accordingly, when the present invention is combined with a nozzle, provided that the outlet crevice of the nozzle does not present vertical, the hollow pipe can be rotated to make the outlet crevice become vertical to ease a user to bite the nozzle for drinking water.
