Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] This utility model relates to a water tank, including a tank body 100 and an indicator component 200.

[0027] like Figure 1 As shown, the interior of the tank 100 is hollow, forming a water cavity 110. An indicator component 200 is installed at the bottom of the water cavity 110. The indicator component 200 includes a movable element 210 and an elastic structure 220. The movable element 210 can be a rod, slider, or other component. The movable element 210 passes through the bottom of the tank 100 and can move up and down within the water cavity 110. When the movable element 210 descends, it extends downwards out of the tank; when it rises, it retracts into the water cavity 110. A slide rail 300 can be provided on the tank, and the movable element 210 is slidably connected to the slide rail 300. The slide rail 300 guides the rising and falling of the movable element 210, ensuring its stability during movement. The elastic structure 220 applies an elastic force to the movable element 210, which drives the movable element 210 to rise. Water tanks are mainly used in toilet products, such as sit-down toilets and squat toilets. In actual use, the water chamber 110 is equipped with an inlet 120 and an outlet 130. The inlet 120 has an inlet valve 400, and the outlet 130 has an outlet valve 500. The inlet 120 is connected to an external water supply system, such as a tap water pipe, and the outlet 130 is connected to the toilet chamber via a pipe. The inlet valve 400 controls the supply of external water to the water chamber 110, and the outlet valve 500 controls the discharge of water from the water chamber 110 through the outlet 130 to flush the toilet chamber. Figure 1As shown, when the water in the water cavity 110 is discharged, the water level in the water cavity 110 drops, and the water pressure exerted by the water in the water cavity 110 on the moving part 210 gradually decreases. At this time, the elastic force exerted by the elastic structure 220 on the moving part 210 gradually exceeds the sum of the water pressure and the weight of the moving part 210, and the elastic structure 220 drives the moving part 210 to gradually rise. Figure 2 As shown, after flushing, external water replenishes the water chamber 110, causing the water level in the chamber to gradually rise. The water pressure exerted on the moving part 210 gradually increases, and the sum of the water pressure and the weight of the moving part 210 gradually exceeds the elastic force of the elastic structure 220. The moving part 210 then gradually descends and extends out of the water tank. The user can roughly judge the water level in the water chamber 110 based on the extension or retraction of the moving part 210 relative to the water tank. A scale 211 can be set on the moving part 210, positioned along the direction of its movement. The current water level in the water chamber 110 can be visually determined through the scale 211. Alternatively, multiple indicator positions can be set on the moving part 210, with different indicator positions representing different water volumes in the water chamber 110. For example, when the scale is visible when the movable part 210 is moved to the middle position, it can be used for half flushing after urination. When the scale is visible when the movable part 210 is moved to the highest position, it means that the water is full and can be used for full flushing. This can reduce water consumption and achieve the purpose of water conservation.

[0028] In one embodiment, such as Figure 1 and Figure 2As shown, the indicating component 200 also includes a flexible sleeve 230. The flexible sleeve 230 is deformable and can be made of a film, foldable plastic, etc. The flexible sleeve 230 has an inner cavity with one open end; in the direction shown in the figure, the lower end of the flexible sleeve 230 is open, while the other parts are sealed. The lower opening of the flexible sleeve 230 can be sealed to the bottom of the water cavity 110 using adhesive, sealing rings, etc. The movable component 210 extends from bottom to top through the water tank into the inner cavity, and the flexible sleeve 230 is fitted onto the movable component 210. When the movable component 210 rises or falls, it causes the circumferential sidewall of the flexible sleeve 230 to deform. The flexible sleeve 230 separates the position where the movable component 210 passes through the water tank from the water cavity 110, thereby achieving a water seal and preventing leakage. Furthermore, the top of the flexible sleeve 230 is made of a rigid material, such as a rigid plastic plate. The top of the movable member 210 is connected to the top of the inner cavity, and the top of the inner cavity rises and falls synchronously with the movable member 210. Water pressure acts on the top of the flexible sleeve 230, indirectly applying pressure to the movable member 210. The elastic structure 220 is a spring 221, which is installed in the inner cavity. The spring 221 can be configured such that its two ends abut against the top of the inner cavity and the bottom of the water tank, respectively; or, the spring 221 can be sleeved on the movable member 210, with its two ends abutting against the bottom of the movable member 210 and the water cavity 110, respectively. When the movable member 210 descends, the spring 221 elastically contracts downwards; when the spring 221 elastically returns to its original position, it pushes the movable member 210 upwards. The flexible sleeve 230 has several grooves 231 on its circumferential sidewall. These grooves 231 can be V-shaped and extend circumferentially along the flexible sleeve 230. The grooves 231 are sequentially distributed along the lifting direction of the moving member 210, resulting in a wavy circumferential sidewall of the flexible sleeve 230. When the moving member 210 rises, it causes the flexible sleeve 230 to deform upwards, unfolding each groove 231. When the moving member 210 descends, it causes the flexible sleeve 230 to deform downwards, folding and closing each groove 231.

[0029] In one embodiment, such as Figure 3As shown, the circumferential sidewall of the flexible sleeve 230 is made of an elastic material. The top of the moving member 210 is connected to the top of the inner cavity. Several grooves 231 are provided on the circumferential sidewall of the flexible sleeve 230. The grooves 231 can be V-shaped and extend circumferentially along the flexible sleeve 230. These grooves 231 are distributed sequentially along the lifting direction of the moving member 210, resulting in a wavy circumferential sidewall of the flexible sleeve 230. The circumferential sidewall of the flexible sleeve 230 constitutes the aforementioned elastic structure 220. When the moving member 210 descends, the circumferential sidewall of the flexible sleeve 230 undergoes downward elastic deformation, and the grooves 231 elastically contract to generate elastic potential energy. After the water pressure decreases, the elastic potential energy is released at the grooves 231, and the grooves 231 elastically expand, causing the moving member 210 to rise. The flexible sleeve 230 is used to achieve a water seal and apply an elastic force to the moving member 210.
