[0002] Conventional toilet water tanks use a traditional floor-standing toilet structure, and the toilet water tank is set above the toilet, occupying a large area of ​​the bathroom floor. For this reason, a hidden water tank structure has been launched on the market, which is also called a wall-mounted water tank. For example, patent number CN201921724459.0 discloses a hidden water tank adapted to a smart toilet and CN202120586739.0 discloses a concealed toilet water tank mounting frame.

[0003] In the existing hidden water tank structure, the inner cavity of the hidden water tank is inside the wall, the upper water inlet is connected to the water inlet pipe, and the lower water outlet is connected to the water outlet pipe; the water tank as a whole, the water inlet pipe and the water outlet pipe are all inside the wall, and need to be sealed with cement or a front baffle after the arrangement is completed; only the control panel and part of the drainage control lever extend or are exposed from the bracket fixing groove at the front end of the water tank. The water outlet end below the hidden water tank is provided with a water outlet and a drain valve; the drain valve is installed at the water outlet and blocked by a drain plug; the user presses the control lever to hook the drain plug through the drainage linkage assembly, so that the drain valve is turned on, thereby discharging the water in the hidden water tank through the water outlet and the outlet pipe.

[0004] The water outlet pipe of the existing hidden water tank is set on the outside of the water outlet; the wall surface of the water outlet pipe and the water outlet is sealed by applying sealing glue or wrapping sealing tape around the outer periphery; however, if the connection between the water outlet and the water outlet pipe is aged and loose, and the sealing glue or sealing tape is aged and ineffective, water leakage will occur at the water outlet. In this case, it is necessary to break open the wall or the front baffle to repair the connection between the water outlet and the water outlet pipe, which is complicated and costly. Therefore, further improvement is needed. Utility Model Content
