AI Technical Summary
The existing plastic water tank structure of smart toilets has problems such as inconvenient installation and maintenance, and easy leakage after aging.
The embedded water tank structure is formed by bonding and sintering the ceramic body and the base. The water tank is directly formed by creating an open part through the mud-plastic sewage pipe and partition at the bottom of the base, utilizing the irregular space inside the ceramic base, thus avoiding secondary installation. The partition is provided with water tank inlet pipe installation hole and overflow port.
It achieves good water tank stability, is not easy to age and eliminates water leakage problems, while making full use of internal space and is suitable for wall-mounted and floor-standing smart toilets.

Abstract
Description
Technical Field
[0001] This utility model relates to a water tank structure for an intelligent toilet. Background Technology
[0002] Most existing water tanks used in smart toilets are external, requiring installation within the wall. Due to installation and maintenance issues and high costs, some designs have opted for water tanks embedded within the ceramic body of the smart toilet. For example, Chinese patent CN215519026U discloses a smart toilet with a small-volume water tank, including a ceramic body with a water tank mounting cavity on the rear side. The water tank is installed within this cavity. The top surface of the ceramic body above the water tank has a mounting opening for a smart toilet seat mount. Because the water tank is relatively low, the smart toilet seat mount can be inserted into the ceramic body through this mounting opening, making the seat flush with the top surface of the ceramic body after installation. This reduces the overall size of the external smart toilet seat component, improving aesthetics and user experience. However, this plastic water tank structure still suffers from inconvenient installation and maintenance, and is prone to leakage due to aging. Summary of the Invention
[0003] The purpose of this invention is to provide a water tank structure for a smart toilet, in order to solve the problems of inconvenient installation and maintenance and easy leakage due to aging of existing plastic water tank structures.
[0004] The purpose of this utility model is achieved as follows: a water tank structure for a smart toilet, wherein the ceramic body of the smart toilet is formed by bonding and sintering a seat and a base. A drain pipe is formed by clay molding at the lower part of the seat, and a partition is formed by clay molding at the position corresponding to the drain pipe outlet on the base. An upward-facing opening is formed by the base plate, the surrounding wall, and the partition. A drain pipe is formed by clay molding along the extension direction of the drain pipe on the partition, and a drain interface is formed by clay molding at the position of the partition aligned with the drain pipe. After the clay-molded seat and the clay-molded base are aligned and a window is opened, the drain pipe is bonded to the partition with mud at the drain interface. The water storage space of the toilet tank is formed by deducting the space occupied by the seat sinking into the opening.
[0005] In this utility model, the base plate, enclosure, partition, and sewage pipe are integrally molded clay.
[0006] In this utility model, the partition is provided with a water tank inlet pipe mounting hole.
[0007] In this utility model, an overflow pipe connecting the sewage pipe and the toilet bowl is formed by clay molding on the outside of the toilet bowl body. A water tank overflow outlet is set at the highest water level set in the water storage space corresponding to the overflow pipe.
[0008] This invention creates an embedded, open ceramic water tank by directly molding a partition inside the ceramic base of the smart toilet. The water tank is directly formed and fired within the ceramic body, eliminating the need for secondary installation and preventing aging and leakage issues. Furthermore, it makes full use of the unused, irregular internal space. Attached Figure Description

[0015] Reference Figures 1 to 5 This embodiment describes the water tank structure of a smart toilet. The ceramic body of the smart toilet is formed by bonding and sintering a seat 1 and a base 2. A drain pipe 3 is molded in clay at the lower part of the seat. A partition 4 is molded in clay at the position corresponding to the drain pipe outlet of the base. An upward-facing open portion A is formed by the base plate 5, the surrounding wall 6, and the partition. A drain pipe 7 is molded in clay along the extension direction of the drain pipe. A drain interface 8 is molded in clay at the position of the partition aligned with the drain pipe. After the molded seat and the molded base are aligned and a window 12 is opened, the drain pipe is bonded to the partition with mud at the drain interface. The water storage space B of the toilet tank is formed by subtracting the space occupied by the seat from the open portion.
[0016] In this utility model, the base plate, enclosure, partition, and sewage pipe are integrally molded clay.
[0017] In this utility model, the partition is provided with a water tank inlet pipe mounting hole 9.
[0018] In this utility model, an overflow pipe 10, which connects the sewage pipe and the toilet bowl, is formed by clay molding on the outside of the toilet bowl. A water tank overflow outlet 11 is provided at the highest water level set in the water storage space corresponding to the overflow pipe.
[0019] The water tank structure of this utility model makes full use of the irregular space inside the ceramic base, and the partition formed is directly demolded from the base and is an integral part of the ceramic base, which has good stability.
[0020] The water tank structure of this utility model is suitable for both wall-mounted smart toilets and floor-standing smart toilets.
[0021] Reference Figures 4 to 5 The ceramic body of the smart toilet includes a seat and a base. After the clay-sculpted seat and base are shaped and cured, they are joined together with mud. The pre-reserved plate on the seat is removed to create a window. At the drain interface, the drain pipe is joined to the partition with mud. After the joint is cured, the ceramic body is sintered into the finished product.
