AI Technical Summary
Existing wall-mounted toilets have complex water tank installations, are difficult to maintain, are prone to leaks in the inlet valve, and have seals that are prone to aging and failure.
The water tank adopts an internal water tank design, which divides the water tank structure into a horizontal tank and a side-standing tank. They are connected by a detachable fixing structure. The side water inlet valve is suspended in the side-standing tank. Sealing gaskets and limiting structures are used to enhance the sealing performance, and a locking structure restricts the rotation of the water inlet pipe.
It simplifies the installation process, reduces maintenance costs, decreases the risk of leakage, and improves the service life and ease of maintenance of the seals.

Abstract
Claims
1. A wall-hung toilet with a built-in water tank, characterized by: include The toilet body has a cavity at its rear. The cavity includes a lower cavity below the toilet bowl and a rear cavity behind the toilet bowl, with the rear cavity extending vertically through the rear of the toilet body. A water tank structure is built into the cavity. The water tank structure includes a horizontal tank and a side tank. The horizontal tank is located in the lower cavity, and the side tank is located in the rear cavity and connected to the side of the horizontal tank via a detachable fixing structure, so that the side tank and the horizontal tank are in communication. A side inlet valve, whose inlet pipe passes through the inner wall of the side upright box and cooperates with the locking structure, so that the side inlet valve is suspended and fixed in the side upright box for supplying water to the inside of the water tank structure. A limiting structure is fixed to the lower part of the toilet body to restrict and constrain the displacement of the tank structure from the lower part of the toilet body.
2. A wall-hung toilet with a built-in water tank as claimed in claim 1, characterized in that: The detachable fixing structure includes a threaded tube located on the side of the horizontal box and a screw-lock nut located inside the side upright box; the threaded tube is inserted into the side through hole of the side upright box and is screwed into the screw-lock nut to fix the side upright box to the side of the horizontal box.
3. A wall-hung toilet with a built-in water tank as claimed in claim 2, characterized in that: It also includes a sealing gasket located between the screw tube and the lock nut. The sealing gasket is sleeved on the screw tube. When the lock nut is tightened, the sealing gasket is elastically deformed by the force exerted by the lock nut along the length of the screw tube to seal the connection gap between the horizontal box and the side box.
4. A wall-mounted toilet with a built-in water tank as described in claim 3, characterized in that: The sealing gasket is located outside the side-standing housing, and a limiting ring is formed on the outer periphery of the spiral tube; the sealing gasket is axially positioned on the spiral tube by the limiting ring, and is deformed by the limiting ring and the outer wall of the side-standing housing under the force of the locking nut.
5. A wall-hung toilet with a built-in water tank as claimed in claim 1, characterized in that: The locking structure includes a stop nut, an anti-rotation plate, and a locking block formed on the outer peripheral wall of the water inlet pipe. The anti-rotation plate is located between the stop nut and the outer wall of the side upright box, and the locking cavity on the edge of the anti-rotation plate is adapted to and engaged with the locking block. The stop nut is screwed to the water inlet pipe and moves axially along the water inlet pipe, causing the anti-rotation plate to axially press against the outer wall of the side upright box to form a surface contact fit, thereby restricting the rotation of the water inlet pipe.
6. A wall-hung toilet with a built-in water tank as claimed in claim 5, characterized in that: The locking structure also includes an anti-rotation groove on the outer wall of the side upright box. The anti-rotation plate is located in the anti-rotation groove and its outer wall is adapted to fit the inner wall of the anti-rotation groove. The axial displacement of the stop nut constrains the anti-rotation plate in the anti-rotation groove.
7. A wall-hung toilet with a built-in water tank as claimed in claim 5, characterized in that: The outer peripheral wall of the water inlet pipe is recessed with two grooves, and the rib between the two grooves is configured as the locking block. The anti-rotation plate is inserted into the groove and engages with the locking block.
8. A wall-hung toilet with a built-in water tank as claimed in claim 6, characterized in that: Both the anti-rotation groove and the anti-rotation plate are arranged in a fan shape or V shape, and the anti-rotation plate is configured as an elastic anti-rotation plate.
9. A wall-hung toilet with a built-in water tank as claimed in claim 1, characterized in that: The limiting structure is configured as a bottom sealing plate, which is fixed to the bottom of the toilet body and forms a surface contact with the bottom surface of the horizontally placed box; the bottom surface of the side box is provided with a transition block, which abuts against the upper surface of the bottom sealing plate.
10. A wall-hung toilet with a built-in water tank as claimed in any one of claims 1 to 9, characterized in that: The horizontally placed box body is formed by blow molding, and the side-standing box body is formed by injection molding.
