Abstract

A water outlet valve structure for a water bag mouthpiece, which includes a mouthpiece, a threaded base disposed on one end of said mouthpiece, a blocking member disposed at one end of said threaded base, and a sleeve base disposed at one end of said blocking member; wherein said blocking member having a push bottom on one side, such that the sleeve base can displace when operating the push bottom from the outside in order to control the water releasing and water stopping functions. By means of the above structure, the user can easily use the mouthpiece to drink water from the water bag, and the mouthpiece can be fixed onto the water outlet valve more securely.

Claims

1. A water outlet valve for a water bag mouthpiece comprising:

a waterpiece, being comprised of a sleeve cylinder and a soft sucking section wrapped around the exterior of said sleeve cylinder, said sleeve cylinder being a threaded one having a penetrating hole, and a fixed ring and a threaded connecting ring respectively disposed on both ends thereon;

a stand extended from one end of said fixed ring and proximate the penetrating hole, and said stand being slightly opened outward;

a protruded member each being disposed on both sides of said stand, and a slit being disposed on one side of said soft sucking section;

a threaded base, disposed at one end of said mouthpiece, and said threaded base having a circular latch groove at one end, and a threaded connecting section extended from another end of the threaded base at the middle thereof for fixing said sleeve cylinder to said threaded connecting section, and said threaded base having a through hole, and a wall disposed at the inner edge of said circular latch groove proximate the center of said hole, and said wall and said circular latch groove defining a groove;

a blocking member, disposed at one end of said threaded base, having a push button at one side, a hole at its center, a plug extended from one side proximate the center of said hole, and a rib ring each disposed at a front end and a rear end of said blocking member;

a sleeve base, disposed on one end of said blocking member, and said sleeve base having a sleeve ring at one end to latch the wall of said threaded base and said circular latch groove to define a groove, and a guide tube being integrally formed and coupled to another end of said sleeve base for connecting the outlet tube of the water bag;

a cut groove being disposed on one side of said sleeve base for accommodating said push button;

a connecting hole being disposed on said sleeve base thereby accommodating the plug of said blocking member into said connecting hole;

thereby a user just needs to push the blocking member to suck the sucking section for drinking water from the water bag, and just needs to push the blocking member back when not draining water from the water bag.
