[0002] The toilet tank is primarily used to store water for flushing and to enable the flushing function. It generally consists of a tank body, an inlet valve, a drain valve, and a flush button. The tank body holds the water; the inlet valve controls the water flow and automatically replenishes the water to the set level; the drain valve opens during flushing for rapid drainage; and the flush button is the component the user uses to trigger the flush. It emerged with the development of sanitary ware to provide convenient and efficient flushing, and through continuous improvement, it has now become an indispensable and highly practical component of the toilet.

[0003] The interior of current toilet tanks is constantly in a humid environment and in continuous contact with flushing water. Various impurities and minerals in the water, combined with repeated flushing and settling, easily cause dirt to gradually build up on the inner walls. This dirt can severely impact the flushing water, making it susceptible to bacterial contamination. While manual cleaning is usually required, the design lacks a mechanism for quick and easy cleaning. Utility Model Content

[0004] The purpose of this utility model is to provide a toilet tank structure to solve the problem that existing water tanks in the background art are prone to accumulating dirt on the inner wall, requiring manual cleaning, and lack a corresponding design that enables quick cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a toilet tank structure, including a tank body and a base disposed at the bottom of the tank body, and a top seat disposed at the top of the tank body;

[0018] Ease of self-operation: Operators simply need to hold the sleeve and pull it out of the inner cavity to move the sleeve within the cavity. A limit ring is used to prevent it from being pulled out completely. The entire operation process is simple and easy to understand. No complicated tools or professional skills are required. Ordinary users can easily start cleaning the inner wall of the water tank, greatly improving the convenience and autonomy of cleaning.

[0019] Structural stability and limit protection

[0020] Stable vertical position of the rotating rod: The washer structure, located below the inner and outer embedded rings, reliably limits the rotation of the rod, ensuring it remains vertical throughout its movement. This stable vertical position facilitates uniform and good contact between the cleaning roller and the inner wall of the water tank, preventing issues such as poor adhesion due to rod tilting, which could lead to cleaning dead zones or uneven cleaning intensity. This ensures comprehensive and effective cleaning.

[0021] Preventing excessive component displacement: The limiting ring for the sleeve rod and the washer for the rotating rod together form a complete limiting system, effectively preventing excessive displacement or detachment of various related components. This not only ensures the coordinated operation of various structures during cleaning operations but also extends the service life of these innovative structures, reduces the risk of failure caused by improper operation or loose parts, and enables the entire cleaning mechanism to function stably for a long time.

[0022] Easier Hygiene Maintenance: Thanks to these innovative structures, users can clean the water tank promptly and conveniently based on its actual dirt level, eliminating the need for the inefficient and difficult-to-clean method of manually flushing water, which greatly reduces the burden of water tank cleaning and maintenance, making overall bathroom hygiene maintenance more worry-free and effortless.

[0023] Ensuring a healthy and hygienic environment: The cleaned inner wall of the water tank effectively reduces bacterial growth, keeping the flushing water source clean and hygienic. When flushing the toilet daily, bacteria and other harmful substances will not spread into the bathroom environment, creating a healthier and more hygienic environment for users, eliminating potential health hazards, and improving people's comfort and sense of security when using the toilet.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figure 1-6 The toilet tank structure shown includes a tank body 3, a base 4 located at the bottom of the lower side of the tank body 3, and a top seat 2 located at the upper side of the tank body 3.

[0033] A water inlet valve 5 is provided on the right side of the base 4, a drain valve 6 is provided on the left side of the base 4, a water stop rod 7 is provided on the left side of the water inlet valve 5, and a water supply pipe 8 is provided at the front connection position of the water inlet valve 5 and the drain valve 6.

[0034] An outer ring 9 is provided at the bottom of the base 4 where it connects to the inner wall of the water tank body 3, and an inner ring 10 is provided at the inner side of the outer ring 9. An upper ring 12 is provided at the bottom of the top seat 2 where it connects to the inner wall of the water tank body 3.

[0035] A rotating rod 15 is connected to the inner side of the outer ring 9 and the inner ring 10. A cleaning roller 11 is provided on the upper side of the rotating rod 15. A ratchet 17 is provided at the internal connection between the rotating rod 15, the outer ring 9, and the inner ring 10. A gasket 18 is provided at the lowest side of the rotating rod 15.

[0036] An inner cavity 16 is provided at the upper middle inner position of the rotating rod 15, a sleeve rod 13 is provided at the inner position of the inner cavity 16, and a limit ring 14 is provided at the lower position of the sleeve rod 13.

[0037] In this embodiment, the first stage is the water intake stage.

[0038] When the toilet tank needs water, water enters the tank body 3 through the inlet valve 5. The stop valve 7 on the left side of the inlet valve 5 will stop water from entering further when a certain water level is reached to prevent the tank from overflowing. At the same time, the water supply pipe 8 will replenish water as needed during the water intake process.

[0039] II. Flushing Stage

[0040] The user can press the flush button 1 to activate the drain valve 6. After the drain valve 6 opens, the water in the tank body 3 is quickly discharged to flush the toilet.

[0041] III. Cleaning Roller Working Stage

[0042] In non-flushing mode, if cleaning of the inner wall of the water tank is required, the lever 15 can be operated manually. The lever 15 moves within the slide rails inside the outer ring 9 and the inner ring 10 via a ratchet 17. Since the outer ring 9 and the inner ring 10 are connected to the water tank body 3 by bolts, the lever 15 is provided with stable support.

[0043] The inner cavity 16 on the upper middle inner side of the rotating rod 15 is connected to the sleeve rod 13 by a nesting connection, and the sleeve rod 13 can move up and down in the inner cavity 16. During the movement of the rotating rod 15, the sleeve rod 13 can be adjusted in position as needed to adapt to different cleaning requirements.

[0044] The gasket 18 at the lowest position of the rotating rod 15 is annular and is connected to the rotating rod 15 by a threaded connection. It is set at the bottom of the outer ring 9 and the inner ring 10 to prevent the rotating rod 15 from moving down too much and to stabilize the rotating rod 15.

[0045] like Figure 1-6 As shown, the sleeve rod 13 is connected to the inner cavity 16 by a nested connection. The sleeve rod 13 can move up and down in the inner cavity 16. The cleaning roller 11 is connected to the rotating rod 15 by a bolt connection. The outer wall of the cleaning roller 11 is in close contact with the inner wall of the water tank body 3. The cleaning roller 11 is made of fiber material. The outer ring 9 and the inner ring 10 are provided with a slide rail that meshes with the ratchet 17 at the connection position. The rotating rod 15 can move in the slide rail through the ratchet 17. The outer ring 9 and the inner ring 10 are connected to the water tank body 3 by bolt connection. The gasket 18 is connected to the rotating rod 15 by a threaded connection. The gasket 18 is set at the bottom of the outer ring 9 and the inner ring 10. The gasket 18 is annular.

[0046] Preferably, after prolonged use of the water tank, dirt and bacteria may accumulate on the inner wall, requiring cleaning. In this case, the user can clean the inner wall of the water tank.

[0047] The user holds the sleeve 13 and pulls it upwards within the inner cavity 16. The sleeve 13 moves within the inner cavity 16, but the presence of the limiting ring 14 prevents it from being fully pulled out. The movement of the sleeve 13 provides the initial power for the subsequent movement of the rotating rod 15 and the cleaning roller 11.

[0048] The movement of the sleeve rod 13 drives the rotating rod 15. The rotating rod 15 moves along the slide rail at the connection between the outer ring 9 and the inner ring 10 using a ratchet 17. During this process, the washer structure is located below the inner ring 10 and the outer ring 9, limiting the structure of the rotating rod 15 and ensuring that the rotating rod 15 is in a vertical state. This vertical state facilitates full contact between the cleaning roller 11 and the inner wall of the water tank, improving the cleaning effect.

[0049] The user rotates the upper ring 12 several times, and through the transmission of the sleeve rod 13 and the rotating rod 15, the cleaning roller 11 rolls on the inner wall of the water tank as the rotating rod 15 moves. The cleaning roller 11 is made of fibrous material and is in close contact with the inner wall of the water tank. During rotation, it can quickly and effectively clean the dirt and bacteria on the inner wall of the water tank.

[0050] In summary, the innovation of this new toilet tank structure lies in the use of the user operating lever 13 to drive the rotating rod 15 and the cleaning roller 11 to move, and the contact between the cleaning roller 11 and the inner wall of the tank to achieve the function of quickly cleaning the inner wall of the tank.

[0051] like Figure 1-4 As shown, a flush button 1 is provided at the upper end of the drain valve 6. The drain valve 6 is connected to the top seat 2 by a snap-fit ​​connection. The top seat 2 is connected to the water tank body 3 by a sleeve connection. The base 4 is connected to the water tank body 3 by a welding connection. The bottom of the inlet valve 5 and the drain valve 6 respectively penetrate the base 4, and a rubber ring is provided at the connection position with the base 4 for sealing.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
