In the water receiving joint, the one-way sealing element is arranged to seal the communication between the water outlet and the water permeable hole in a one-way manner, the sealing direction is from the water permeable hole to the water outlet, and water flows from the inside of the container to the leakage stop valve, so that the one-way sealing element acts to realize automatic sealing, thereby preventing foreign matters from being arranged between the blocking element and the water inlet channel, preventing the water channel from being blocked, causing water leakage or preventing water in the water container from flowing out of the leakage stop valve and causing leakage. In the water receiving joint, the leakage stop valve and the one-way sealing element are arranged, so that the water receiving joint is provided with double leakage prevention and is safer.

Further, as shown in fig. 5 and 6, the lower end of the leakage stop valve 12 is provided with a press-opening projection 1271 protruding downward for pressing down the valve body 2001 of the water supply joint 200 when the water receiving joint 1 is connected to the corresponding water supply joint 200, thereby communicating the water receiving joint 1 with the water supply joint 200. Generally, the water supply connector 200 is installed on the base 300, the water supply connector 200 is connected to a water supply pipe, the water receiving connector 1 is installed on the bottom of the container, when in use, the water receiving connector 1 is placed on the water supply connector 200 to form a butt joint, then the press-opening projection 1271 is vertically opposite to the valve core 2001, and the press-opening projection 1271 presses down and pushes open the valve core 2001, so that the water supply connector 200 is opened, and the water receiving connector 1 is communicated with the water supply connector 200. In this embodiment, the press-open projection 1271 is provided on the second valve body 127.

Example 2:

the water receiving connector 1 of the present embodiment is substantially the same as the water receiving connector 1 of embodiment 1 except that:

as shown in fig. 7 and 8, the valve seat 113 has an extension 1131 in a hollow cylindrical shape, the extension 1131 extends into the valve cover 114, the water outlet 123 is located in the extension 1131, the one-way sealing member 13 includes an elastic valve located above the water outlet, the elastic valve is in a circular ring shape, an inner periphery of the elastic valve is provided with an annular locking portion 132, an outer periphery of the elastic valve is clamped between the extension 1131 and the valve cover 114, the locking portion 132 abuts against an upper end face of the leakage stop valve 12, and when the water inlet channel does not supply water, the locking portion 132 blocks a radial gap between the extension 1131 and the leakage stop valve 12; when water is supplied from the water inlet passage 124, water flows out of the water outlet 123 and pushes open the latch 132 into the water permeable hole 112. Namely, the outer ring of the elastic valve is partially arranged on the extension section 1131, and the part close to the inner ring is lapped on the leakage-stopping valve 12, so that the water outlet 123 in the extension section 1131 is separated from the water permeable port outside the extension section 1131 to cut off and communicate, thereby realizing sealing and leakage prevention.
