Description

Technical Field

[0001] This utility model relates to the field of toilet tank technology, specifically a water tank with automatic water level adjustment. Background Technology

[0002] In daily life, the toilet is an indispensable sanitary fixture, and the water level control of the toilet tank has an important impact on the normal use and water-saving performance of the toilet.

[0003] According to application number CN200620000449.9, a toilet water seal height maintaining device is disclosed. This device replenishes the water level of the toilet water seal by introducing water into the overflow pipe connected to the lower outlet of the toilet tank. The toilet water seal height maintaining device has a water level control mechanism connected to the side wall of the overflow pipe and located at a position normally lower than the water level of the tank. The water level control mechanism has a water inlet passage for guiding the water flow from the tank to the overflow pipe. By means of the above methods, the water level of the toilet water seal can be actively replenished and the water level of the toilet water seal can be effectively maintained at a certain height.

[0004] The toilet tanks in the above cases do not have an automatic water level adjustment function. They can only replenish the water seal through a fixed overflow pipe and cannot actively adjust the overall water level according to the usage scenario, such as flushing power requirements. This results in insufficient water level during high flushing or water waste during low demand. Components such as the float link and spring are prone to rust and jamming after long-term immersion, leading to water level control failure and problems such as tank overflow or insufficient water replenishment. Therefore, we provide a water tank with automatic water level adjustment. Utility Model Content

[0020] Please see Figure 1-5 An automatically adjustable water tank includes a tank body 1, a water level regulating component 2 inside the tank body 1, a limit fixing component 3 on the water level regulating component 2, an inlet pipe 4 fixedly connected to the left side of the tank body 1 and communicating with it, a drain pipe 5 fixedly connected to the bottom of the tank body 1 and communicating with it, a first solenoid valve 6 on the inlet pipe 4, a second solenoid valve 7 on the drain pipe 5, a one-way valve on the inlet pipe 4, a tank cover on the top of the tank body 1, the bottom of the tank cover contacting the top of the tank body 1, a control panel embedded in a groove on the rear side of the top of the tank cover, and a control button fixedly connected to the top of the tank cover.

[0021] The water level regulating assembly 2 includes a connecting plate 21, which is located on the right side of the bottom of the inner wall of the water tank body 1. The side of the connecting plate 21 closest to the inner wall of the water tank body 1 is in contact with the inner wall of the water tank body 1. A connecting block 22 is fixedly connected to the top left side of the connecting plate 21. A vertical plate 23 is fixedly connected to the bottom of the connecting block 22. The bottom of the vertical plate 23 is fixedly connected to the connecting plate 21. A float plate 24 is slidably connected to the surface of the vertical plate 23. The side of the float plate 24 closest to the connecting plate 21 is in slidable contact with the connecting plate 21. An electric push rod 25 is fixedly connected to the top of the connecting block 22. The bottom end of the electric push rod 25 passes through the connecting block 22 and extends to its outside. A moving block 26 is fixedly connected to the bottom end of the electric push rod 25. A pressure sensor 27 is fixedly connected to the bottom of the moving block 26. A squeezing block 28 is fixedly connected to the top of the float plate 24 and at the position corresponding to the pressure sensor 27. The top of the squeezing block 28 is in contact with the bottom of the pressure sensor 27.

[0022] The electric push rod 25, pressure sensor 27 and first solenoid valve 6 are electrically connected to the control panel, and the second solenoid valve 7 is electrically connected to the control button.

[0023] The limiting and fixing component 3 includes a recess 31, which is installed on the right side of the top of the connecting plate 21. A pull block 32 is provided on the left side of the recess 31. The side of the pull block 32 close to the recess 31 is in contact with the recess 31. A locking block 33 is fixedly connected to the right side of the pull block 32. A slot 34 is provided on the right side of the inner wall of the water tank body 1, corresponding to the position of the locking block 33. The right side of the locking block 33 passes through the recess 31 and the slot 34 from left to right and extends into the inside of the slot 34, contacting the inner wall of the slot 34. An adjusting block 35 is fixedly connected to the surface of the locking block 33 and inside the recess 31. A buffer spring 36 is sleeved on the surface of the locking block 33. The elastic force of the buffer spring 36 ensures the stability of the locking block 33 when inserted into the slot 34.

[0024] A positioning block 37 is fixedly connected to the left side of the bottom of the connecting plate 21. A positioning groove 38 is provided at the bottom of the inner wall of the water tank body 1, corresponding to the position of the positioning block 37. The bottom of the positioning block 37 passes through the positioning groove 38 and extends into it to contact the inner wall of the positioning groove 38. By setting the positioning block 37 and the positioning groove 38, it is ensured that the water level regulating component 2 is accurately aligned during installation, avoiding the float 24 from getting stuck due to installation deviation, and improving the reliability of the regulating system. When the positioning block 37 is inserted into the positioning groove 38, it can be ensured that the locking block 33 can be accurately inserted into the locking slot 34.

[0025] The top and bottom of the inner wall of the concave block 31 are provided with sliding grooves 39, and the top and bottom of the adjusting block 35 are fixedly connected with sliders 310 that slide in contact with the inner wall of the sliding grooves 39. By setting the sliding grooves 39 and sliders 310, the stability of the adjusting block 35 when moving left and right is improved.

[0026] When the water level regulating component 2 needs to be removed from the water tank body 1, first pull the tank cover upward to open the top of the water tank body 1, then pull the pull block 32 to the left. The pull block 32 drives the locking block 33 to move to the left, and the locking block 33 drives the adjusting block 35 to press the buffer spring 36 to the left. The locking block 33 moves to the left and separates from the locking groove 34. Then, pull the connecting plate 21 upward. The connecting plate 21 drives the positioning block 37 to move upward, so that the positioning block 37 and the positioning groove 38 separate, and the water level regulating component 2 can be removed from the water tank body 1.

[0027] The water level of the float 24 is monitored in real time by the pressure sensor 27. The position of the pressure sensor 27 is automatically adjusted by the electric push rod 25, thereby changing the rising position of the float 24 and achieving the effect of automatic water level adjustment. The limit fixing component 3 is set to ensure the stability of the water level adjustment component 2 installed in the water tank. At the same time, it is convenient to remove the water level adjustment component 2 from the water tank for maintenance and repair, which improves the flexibility of use.

[0028] When in use, the user sets a high water level, such as 6L, through the control panel. The electric push rod 25 drives the pressure sensor 27 to move up to the maximum stroke, which raises the upper limit of the float 24 and increases the water storage capacity of the tank. When a low water level, such as 3L, is set, the electric push rod 25 moves down and the upper limit of the float 24 is lowered, reducing the water storage capacity.

[0029] Pressing the control button causes the second solenoid valve 7 on the drain pipe 5 to open quickly and fully, allowing water in the tank body 1 to be discharged into the toilet through the drain pipe 5, thus flushing. At the same time, as the water level drops, the float 24 separates from the pressure sensor 27. The pressure sensor 27 detects a sudden drop in pressure, and the control panel anticipates the water replenishment demand. At this time, the control panel can activate the electric push rod 25 to raise or lower the pressure sensor 27, adjusting the upper limit of the float 24 to change the water level. After flushing, the first solenoid valve 6 immediately opens to replenish water.

[0030] The water in the water tank 1 causes the float 24 to rise. When the float 24 causes the squeezing block 28 to come into contact with the pressure sensor 27, the pressure sensor 27 senses the pressure value and transmits the signal to the control panel. The control panel then immediately closes the first solenoid valve 6 to stop water replenishment.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
