[0020] The following detailed implementation provides a plurality of different embodiments or examples for implementing the utility model. Of course, these are only embodiments or examples and are not intended to be limiting. In addition, repeated reference numbers may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the utility model, and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0021] As Figures 1 to 4 ​The diagram shows a water tank structure, including a water tank body 1, which has an upper-opening cavity 2. The lower end of the cavity 2 is connected to a drain pipe 3. A movable pipe 4 is movably arranged inside the drain pipe 3. A sealing ring abuts between the drain pipe 3 and the movable pipe 4. Several hanging parts 6 are arranged vertically at intervals on one side of the cavity 2. The upper end of the movable pipe 4 is rotatably provided with a hook 7 that can be hooked to any of the hanging parts 6. The weight of the movable pipe 4 is greater than its buoyancy.

[0022] Specifically, because the weight of the movable pipe is greater than its buoyancy, it maintains a downward-sinking state. A sealing ring between the movable pipe and the drain pipe prevents leakage. Furthermore, by hooking it to attachment points at different heights, the height of the movable pipe within the tank cavity can be manually adjusted. When the hook is not engaged, the upper opening of the movable pipe overlaps with the upper opening of the drain pipe, allowing water to drain directly from the tank cavity through the movable pipe without water accumulation. When the hook is engaged with one of the attachment points, the upper opening of the movable pipe rises, allowing water to accumulate in the tank. If the water level in the tank is too high, water exceeding the height of the movable pipe drains through the upper opening, eliminating the need for a separate overflow hole.

[0023] Furthermore, a filter screen 8 is detachably connected to the upper part of the movable pipe 4. This filter screen ensures that the trough can filter water during drainage or overflow, preventing sewer blockage, and users can clean and maintain the trough by removing it.

[0024] Furthermore, the length of the drain pipe 3 is greater than or equal to the length of the movable pipe 4. Consequently, the lower end of the drain pipe can be directly connected to an external drain pipe. Even if the sealing ring between the drain pipe and the movable pipe wears down, causing leakage, the water can still flow through the drain pipe into the external drain pipe, preventing overflow and leakage.

[0025] Furthermore, the cavity 2 includes a first cavity 21 and a second cavity 22 that are interconnected, wherein the width of the first cavity 21 is smaller than the width of the second cavity 22. Furthermore, both the first cavity 21 and the second cavity 22 have support platforms 23 along their edge contours on their inner sides, capable of supporting and placing cutting boards or filter baskets. Thus, different cavity widths can accommodate cutting boards / filter baskets of different lengths or widths.

[0026] Furthermore, a limiting protrusion 24 protrudes inward at the connection between the first cavity 21 and the second cavity 22. This limiting protrusion effectively separates the support platforms for the first and second cavities, preventing the cutting board / filter basket placed in the first cavity support platform from slipping and falling into the second cavity due to displacement.

[0027] Furthermore, the drain pipe 3 is located at the corner of the cavity 2, which facilitates the use of the cavity space.

[0028] Furthermore, the hook 7 adopts a stainless steel spring clip. Specifically, the stainless steel spring clip is a relatively mature existing technology, and its structural principle will not be described in detail here. It is equivalent to the structure disclosed in announcement number CN221307432U. Thus, the stainless steel spring clip is fixed to the hook part, which effectively prevents the movable pipe from detaching from the drain pipe. Moreover, the stainless steel spring clip is easy to disassemble and install.

[0029] Based on the accompanying drawings and the foregoing display and description of the basic principles, main features, and advantages of this utility model, those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
