[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0032] It should be noted that in this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element of this utility model must have a specific orientation, and therefore should not be construed as a limitation of this utility model. Example
[0033] Cooperate Figures 1 to 5 As shown, this utility model discloses a toilet tank installation structure, specifically including:
[0034] The toilet seat has a mounting cavity at its bottom, and a toilet mounting part is provided in the mounting cavity of the toilet seat.
[0035] A water tank, wherein the water tank is disposed in the mounting cavity, and the water tank is provided with a water tank mounting part;
[0036] The connector includes a first connecting part and a second connecting part, wherein the first connecting part is installed and fixed to the water tank mounting part, and the second connecting part is connected and fixed to the toilet mounting part.
[0037] The toilet is either a wall-hung toilet or a floor-standing toilet. The toilet seat is made of ceramic and includes a ceramic bowl. An installation cavity is located at the bottom of the toilet seat, with the bowl positioned in the upper middle part of the seat. The space between the bowl and the bowl forms the installation cavity, and the toilet seat has a corresponding installation part within the cavity. The water tank is a plastic tank, housed within the installation cavity, and also has a tank installation part. Connectors are used to install and fix the water tank within the installation cavity. Specifically, a first connecting part and a second connecting part are included. The first connecting part is fixed to the tank installation part, and the second connecting part is fixed to the toilet installation part. The water tank is thus fixed within the installation cavity via the connectors (the first and second connecting parts).
[0038] Installing the water tank inside the mounting cavity at the bottom of the toilet seat effectively utilizes the space within the toilet seat (the shape of the urinal necessitates a certain amount of space between it and the bottom of the toilet seat; using this space for the water tank makes full use of the toilet seat's space). The water tank achieves a concealed effect, making the entire toilet's appearance simpler and more aesthetically pleasing, while having virtually no impact on the toilet seat's volume, resulting in a smaller overall toilet size. Furthermore, the water tank is connected and fixed using connectors, ensuring a more secure installation.
[0039] Cooperate Figures 2 to 5 As shown, in this embodiment, the water tank mounting part and the first connecting part, as well as the toilet mounting part and the second connecting part, are connected and fixed by fasteners. Specifically, the connecting part is an iron plate. The water tank mounting part is located at the bottom of the water tank, and the first connecting part is a horizontally arranged plate that supports the bottom of the water tank and is installed and fixed to the water tank mounting part. The water tank mounting part and the first connecting part have corresponding vertical holes. Fasteners pass through the corresponding vertical holes in the water tank mounting part and the first connecting part and are locked in place, thereby realizing the installation and fixation of the water tank mounting part and the first connecting part. The fasteners connecting the water tank mounting part and the first connecting part are screws. By placing the water tank mounting part at the bottom of the water tank and correspondingly setting the horizontal plate to support and fix it to the bottom of the water tank, the horizontal plate of the connecting part provides good support for the water tank, making the water tank more secure.
[0040] The second connecting part is a vertically arranged plate, which is installed and fixed to the toilet mounting part. The toilet mounting part and the second connecting part are provided with corresponding horizontal holes. Fasteners pass through the horizontal holes of the toilet mounting part and the second connecting part and are locked and fixed, thereby realizing the locking and fixing of the toilet mounting part and the second connecting part, and ultimately realizing the installation and fixing of the water tank. The fastener connecting the toilet mounting part and the second connecting part is a bolt.
[0041] Specifically, the toilet mounting part is a protruding edge extending downward from the bottom of the toilet bowl. The protruding edge is integrally formed with the toilet bowl and the toilet seat, ensuring a secure installation of the water tank.
[0042] Two connectors are provided, located on the left and right sides of the bottom of the water tank, respectively. This enhances the stability of the water tank installation.
[0043] In this embodiment, the water tank is O-shaped and surrounds the bottom of the toilet bowl. This design, with the water tank surrounding the toilet bowl, further utilizes space and makes the overall structure more compact.
[0044] Cooperate Figures 2 to 4As shown, the toilet tank installation structure of this utility model also includes a three-way valve. The three-way valve connects to the municipal water supply pipe, the personal hygiene water supply pipe, and the flushing pipe. The municipal water supply pipe and / or the personal hygiene water supply pipe and / or the flushing pipe can be arranged around the perimeter of the water tank. The municipal water supply pipe connects to the municipal water supply, providing water for the entire toilet. The personal hygiene water supply pipe provides flushing water to the smart toilet seat. The flushing pipe connects to the inlet valve, supplying water to the tank. The three-way valve is located inside the installation cavity, specifically below the tank, behind the tank, or near the bottom of the toilet bowl. One or any two or three of the municipal water supply pipe, personal hygiene water supply pipe, and flushing pipe can be arranged around the perimeter, depending on actual needs.
[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
