Description

Technical Field

[0001] This utility model relates to the field of water tank technology, specifically a dual-chamber water-saving water tank. Background Technology

[0002] Traditional toilet tanks are typically single-chamber designs, with a fixed water volume per flush (e.g., 6-9 liters), leading to water waste when flushing liquid waste. While some dual-button tanks can achieve two flush settings, they suffer from the following problems: the dual chambers require two separate water inlet / drainage systems, resulting in a complex structure; and relying on mechanical control with a float valve, excessive water may still be discharged during a half flush, leading to inaccurate water volume adjustment and unnecessary water waste. To address these issues, we propose a dual-chamber water-saving tank to solve the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a dual-chamber water-saving tank to solve the problems mentioned in the background art.

[0005] Furthermore, the height of the partition plate is lower than the height of the side wall of the water tank body, and the gap between the top of the partition plate and the top of the inner wall of the water tank body forms an overflow channel.

[0006] Furthermore, a connecting pipe is fixedly installed on the partition plate, and a third solenoid valve is installed on the connecting pipe.

[0007] Furthermore, a first button and a second button are respectively installed on the top of the water tank body to cooperate with the first solenoid valve and the second solenoid valve, and a third button is installed on the right side of the water tank body to cooperate with the third solenoid valve.

[0008] Furthermore, the water level sensor, the first solenoid valve, the second solenoid valve, and the third solenoid valve are electrically connected to the control module.

[0009] Furthermore, the water inlet pipe is specifically made of plastic or metal with corrugated sections.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model divides the water tank body into a large-capacity chamber and a small-capacity chamber using a partition plate. Depending on the actual flushing volume required, either the first or second button can be pressed. Through the electrical connection of the control module, the first or second solenoid valve can be opened respectively. When the first solenoid valve is opened, the water stored in the large-capacity chamber can be discharged through the first water inlet pipe, the three-way pipe, and the outlet pipe. Similarly, when the second solenoid valve is opened, the water stored in the small-capacity chamber can be discharged through the second water inlet pipe, the three-way pipe, and the outlet pipe, thus avoiding the problem of excessive water discharge. This dual-chamber water-saving tank has a reasonable structural design, is easy to use, and adopts a single inlet / drainage system, reducing operating costs. The electrically controlled design effectively ensures the accuracy of drainage, preventing excessive water discharge and avoiding unnecessary water waste, resulting in good performance.

[0015] 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.

[0016] Please see Figure 1-2A dual-chamber water-saving tank includes a tank body 1. A water inlet pipe 2, which is fixedly connected to the back of the tank body 1 and communicates with it, is made of corrugated plastic or metal. This allows for easy connection to a water supply after the tank body 1 is installed. A partition plate 3 is installed on the inner wall of the tank body 1, dividing the internal space into a large-volume chamber 4 and a small-volume chamber 5. The small-volume chamber 4 is specifically for flushing liquid waste such as urine, with a drainage volume controlled at 1.5-2L. The large-volume chamber 5 handles solid waste, with a drainage volume of 4-6L. Water level sensors 6 are installed on the inner wall of the tank body 1 at positions corresponding to the large-volume chamber 4 and the small-volume chamber 5. The water level sensor 6 can monitor the water volume in the large volume chamber 4 and the small volume chamber 5 in real time to achieve rapid water replenishment. The control module 7 is installed on the left side of the water tank body 1. The bracket 8 is fixedly installed on the front side of the water tank body 1 by bolts. A three-way pipe 9 is installed on the bracket 8. The first water pipe 10 and the second water pipe 11 are fixedly connected to the positions of the large volume chamber 4 and the small volume chamber 5 on the front of the water tank body 1, respectively. One end of the first water pipe 10 and the second water pipe 11 are respectively connected to the two water inlet ends of the three-way pipe 9. A water outlet pipe 12 is installed on the water outlet end of the three-way pipe 9. A first solenoid valve 13 and a second solenoid valve 14 are respectively installed on the first water pipe 10 and the second water pipe 11.

[0017] The height of the partition plate 3 is lower than the height of the side wall of the water tank body 1. The gap between the top of the partition plate 3 and the top of the inner wall of the water tank body 1 forms an overflow channel 15, which can prevent the small volume cavity 7 from being overloaded.

[0018] A connecting pipe 16 is fixedly installed on the partition plate 3. A third solenoid valve 17 is installed on the connecting pipe 16. The water level sensor 6, the first solenoid valve 13, the second solenoid valve 14 and the third solenoid valve 17 are electrically connected to the control module 7. When the water in the small volume chamber 5 is insufficient, the control module 7 controls the third solenoid valve 17 to open, so that the water in the large volume chamber 4 can be replenished to the small volume chamber 5 in time.

[0019] The top of the water tank body 1 is equipped with a first button 18 and a second button 19, which are used in conjunction with the first solenoid valve 13 and the second solenoid valve 14. By pressing the first button 18 and the second button 19, the water in the large volume chamber 4 and the small volume chamber 5 can be discharged respectively. The right side of the water tank body 1 is equipped with a third button 20, which is used in conjunction with the third solenoid valve 17. When there is insufficient water in the small volume chamber 5, the third solenoid valve can also be opened by pressing the third button 20.

[0020] This dual-chamber water-saving tank features a reasonable structural design and is easy to use. It employs a single inlet / drainage system, reducing operating costs. The electronically controlled design effectively ensures accurate drainage, preventing excessive water discharge and avoiding unnecessary water waste, resulting in good performance.

[0021] Working principle: The water tank body 1 is divided into a large volume chamber 4 and a small volume chamber 5 by the partition plate 3. According to the actual flushing volume, the first button 18 or the second button 19 can be pressed. Through the electrical connection of the control module 7, the first solenoid valve 13 or the second solenoid valve 14 can be opened respectively. When the first solenoid valve 13 is opened, the water stored in the large volume chamber 4 can be discharged through the first water pipe 10, the three-way pipe 9 and the water outlet pipe 12. Similarly, when the second solenoid valve 14 is opened, the water stored in the small volume chamber 5 can be discharged through the second water pipe 11, the three-way pipe 9 and the water outlet pipe 12, thereby avoiding the problem of excessive water discharge.
