<p>A self-locking liquid extraction device for bagged water, comprising: a water bag (0), a liquid extraction head (1), a sealing ring (2), a locking tray (3), a spring (4), a liquid extraction device seat (5), a nozzle (6), a drain pipe (7), a sealing ring mounting groove (8), a locking ring (9), and a water bag receptacle (10). The locking ring (9) is provided in the center of the locking tray (3) and the diameter of the locking tray is smaller than the liquid extraction device seat (5). The sealing ring (2), which acts as a limiter for the locking tray (3), is positioned between the sealing ring mounting groove (8) and the portion where the cone tip and the round base of the liquid extraction head (1) meet. The round base portion of the liquid extraction head (1) passes through the locking ring (9) and is mounted on the nozzle (6). The spring (4) is provided below the locking tray (3). The insertion point of the water bag is automatically locked, under the action of the spring (4), when the locking ring (9) and the sealing ring (2) are pushed together.</p> |
