[0002] Water softeners are installed at the main water inlet of a household water system to treat raw water. Leaks in water softeners can cause significant damage. Currently, leak detection for water softeners primarily uses external leak detectors. This method can only detect leaks outside the water softener or within the space where the water softener is located; it cannot detect leaks in the internal piping of the water softener or in the downstream water supply lines. Utility Model Content

[0003] The purpose of this utility model is to provide a water softener that solves the problem that existing water softeners cannot detect whether there are leaks in the internal pipes and the water supply pipes at the back end; another purpose of this application is to provide a water treatment system.

[0005] Organism;

[0006] A control valve is disposed within the machine body and has an inlet and an outlet; the control valve includes a control unit;

[0007] A water outlet pipe is connected to the water outlet and extends out onto the outside of the machine body;

[0008] A pressure detection unit is installed in the water outlet pipe and located inside the machine body. The pressure detection unit is electrically connected to the control unit.

[0009] In some embodiments, the water softener further includes a first valve disposed within the machine body, located in the water outlet pipe on the side of the pressure detection unit away from the water outlet, and electrically connected to the control unit.

[0010] In some embodiments, the water softener further includes:

[0011] A water inlet pipe is connected to the water inlet and extends out onto the outside of the machine body;

[0012] The second valve is installed in the water inlet pipe and located inside the machine body, and the second valve is electrically connected to the control unit.

[0013] In some embodiments, both the first valve and the second valve are solenoid valves.

[0014] In some embodiments, the control valve has an operating position and a closed position. When the control valve is in the operating position, the inlet is in an open state; when the control valve is in the closed position, the inlet is in a closed state.

[0015] In some embodiments, the water outlet pipe has a quick-connect interface, and the pressure detection unit is detachably inserted into the quick-connect interface.

[0016] In some embodiments, the pressure detection unit is a ceramic pressure sensor.

[0017] In some embodiments, the water softener further includes an alarm unit, which is electrically connected to the control unit.

[0018] In some embodiments, the water softener further includes a display unit electrically connected to the control unit.

[0019] Accordingly, the water treatment system described in this application includes a water softener as described in any of the foregoing embodiments.

[0020] Beneficial Effects: Compared with the prior art, a water softener according to an embodiment of this application includes a body, a control valve, an outlet pipe, and a pressure detection unit. The control valve is located inside the body and has an inlet and an outlet. The control valve includes a control unit. The outlet pipe is connected to the outlet and extends out onto the outside of the body. The pressure detection unit is located in the outlet pipe and is electrically connected to the control unit. By setting a pressure detection unit in the outlet pipe inside the body, the pressure in the water softener's outlet pipe can be detected in real time. By determining whether the pressure detected by the pressure detection unit is within the normal operating range of the water softener, it is possible to determine whether there is leakage in the internal and external pipes of the water softener, thereby improving the safety of the water softener. Compared with a leakage detection device installed on the outside of the body, the leakage detection results are more accurate and leakage problems can be detected earlier. At the same time, by switching between multiple valves, the specific location of the leak can be further determined, which facilitates subsequent targeted maintenance and improves maintenance efficiency.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

Similarly, "parallel" means completely parallel or almost completely parallel, for example, the range of completely parallel angles from 10° is considered parallel.

[0028] Please refer to the following: Figure 1 and Figure 2 A water softener includes a body 1, a control valve 2, a water outlet pipe 3, and a pressure detection unit 4. The control valve 2 is located inside the body 1 and has an inlet 21 and an outlet 22. The control valve 2 includes a control unit 23. The water outlet pipe 3 is connected to the outlet 22 and extends out to the outside of the body 1. The pressure detection unit 4 is located inside the body 1 and is electrically connected to the control unit 23.

[0029] In this embodiment, a pressure detection unit 4 is installed in the water outlet pipe 3 inside the body 1. This allows for real-time monitoring of the pressure within the water outlet pipe 3. By determining whether the pressure detected by the pressure detection unit 4 is within the normal operating range of the water softener, leaks in both internal and external pipes can be identified, improving the safety of the water softener. Compared to installing a leak detection device external to the body 1, this method provides more accurate leak detection and allows for earlier detection of leaks. Furthermore, by switching between multiple valves, the specific location of the leak can be determined, facilitating targeted maintenance and improving repair efficiency.

[0030] Specifically, in this embodiment, when the control valve 2 is in the working position, raw water flows from the inlet 21 through the control valve 2, then flows out from the outlet 22 of the control valve 2 into the outlet pipe 3, and finally flows into the main outlet pipe. During this process, the pressure detection unit 4 monitors the pressure in the outlet pipe 3 in real time. In the initial state, when no one is using water in the downstream pipe and the pressure in the outlet pipe 3 remains stable for a certain period of time, the pressure value output by the pressure detection unit 4 is P1 kPa, and the pressure value P kPa detected by the pressure detection unit 4 in real time satisfies: P1-P2≤P≤P1+P2, where P2 is the pressure fluctuation value. Then it is determined that there is no leakage in the downstream water circuit and the control valve 2 and no one is using water. When the pressure sensor outputs a pressure value P kPa that decreases but remains within the range of P3 ≤ P ≤ P4 (where P1 - P2 > P4), it is determined that someone is using water downstream, rather than there is a leak. When a pressure change occurs and it is outside the ranges of P1 - P2 ≤ P ≤ P1 + P2 and P3 ≤ P ≤ P4, it is determined that there may be a leak in control valve 2 or the downstream pipeline. Correspondingly, subsequent leak handling can be carried out, such as issuing an alarm to remind the user or directly shutting off the water supply for investigation.

[0031] Of course, it is understood that the water softener in this embodiment of the application also includes structures such as a brine tank 20 and a resin tank 10. Both the brine tank 20 and the resin tank 10 are located inside the body 1 and are connected to the control valve 2, which can realize normal water treatment work.

[0032] Please continue to refer to the following: Figure 1and Figure 2 In some embodiments, the water softener also includes a first valve 5, which is disposed inside the body 1, located in the water outlet pipe 3, and on the side of the pressure detection unit 4 away from the water outlet 22. The first valve 5 is electrically connected to the control unit 23.

[0033] In this embodiment, by setting a first valve 5, the opening and closing of the water outlet pipe 3 can be controlled. By utilizing the cooperation of the first valve 5, the pressure detection unit 4, and the control unit 23, the first valve 5 can be further closed when the pressure detection unit 4 detects leakage at the control valve 2 or the downstream pipe. At this time, segmented detection can be achieved to determine whether the leakage is at the control valve 2 or the downstream pipe, thus further locating the leakage position.

[0034] The specific judgment method is as follows: Move control valve 2 to the closed position and close the first valve 5. Further determine whether control valve 2 or the downstream pipeline is leaking by detecting changes in the pressure value of the pressure detection unit 4. When control valve 2 is in the closed position, close the first valve 5. The pressure detection unit 4 is located between the outlet 22 of control valve 2 and the first valve 5. If control valve 2 is not leaking, the pipeline between control valve 2 and the first valve 5 should be under pressure. Therefore, if the pressure value detected by the pressure detection unit 4 remains stable at this time, it can be determined that control valve 2 is not leaking and that control valve 2 can smoothly move to the closed position. In this case, further open the first valve 5 and continue to monitor the pressure value of the pressure detection unit 4. If the pressure value drops to 0, it is determined that there is a leak in the downstream water circuit. If the pressure of the pressure detection unit 4 gradually decreases when control valve 2 is in the closed position and the first valve 5 is closed, it indicates that control valve 2 is leaking.

[0035] Please continue to refer to the following: Figure 1 and Figure 2 In some embodiments, the water softener also includes an inlet pipe 6 and a second valve 7. The inlet pipe 6 is connected to the inlet 21 and extends out to the outside of the body 1. The second valve 7 is disposed in the inlet pipe 6 and located inside the body 1. The second valve 7 is electrically connected to the control unit 23.

[0036] In this embodiment, an inlet pipe 6 is connected to the main inlet 21 to provide raw water for the water softener. A second valve 7 is installed on the inlet pipe 6, which can be shut off promptly in case of leakage from the control valve 2, thus shutting off the water softener's inlet pipe 6 and preventing further leakage. This also allows for further investigation into potential leaks.

[0037] Furthermore, in this embodiment, both the first valve 5 and the second valve 7 are electrically connected to the control unit 23, specifically via a data cable connection, enabling the control unit 23 to control the opening and closing of the first valve 5 and the second valve 7.

[0038] In some embodiments, the first valve 5 and the second valve 7 are both solenoid valves.

[0039] In this embodiment, both the first valve 5 and the second valve 7 can be solenoid valves. Upon receiving the control signal from the control unit 23, they can achieve high-precision control with fast response and high reliability, thus ensuring reliable control of the inlet pipe 6 and the outlet pipe 3. Furthermore, solenoid valves have low energy consumption. During normal operation of the water softener, the first valve 5 and the second valve 7 may need to remain open for extended periods, or the valves may need to remain closed for extended periods if the water softener leaks but cannot be repaired for a long time. In these situations, the low energy consumption helps reduce operating costs. Additionally, using solenoid valves for the first valve 5 and the second valve 7 facilitates automated control.

[0040] Please continue to refer to the following: Figure 1 and Figure 2 In some embodiments, the control valve 2 has an operating position and a closed position. When the control valve 2 is in the operating position, the inlet 21 is in the open state; when the control valve 2 is in the closed position, the inlet 21 is in the closed state.

[0041] In this embodiment, the control valve 2 can have a working position and a closed position. When the control valve 2 is in the working position, the inlet 21 is open, and water entering the inlet pipe 6 can flow through the inlet 21, through the control valve 2, into the resin tank 10, and then out through the outlet 22 into the outlet pipe 3. When the control valve 2 is in the closed position, the inlet 21 is closed, and water in the inlet pipe 6 can no longer be injected into the control valve and the downstream water circuit. Therefore, by controlling the opening and closing of the inlet 21 of the control valve 2, the pressure values ​​of the pressure detection unit 4 under different states can be easily realized, thereby enabling segmented detection and facilitating the identification of leakage points.

[0042] It should be noted that in this embodiment, when the control valve 2 is in the closed position, not only is the inlet 21 closed, but the water injection and brine suction port and the sewage discharge port on the corresponding control valve 2 are also closed. At this time, only the outlet 22 is open.

[0043] like Figure 1 As shown, in some embodiments, the water outlet pipe 3 has a quick-connect interface 31, and the pressure detection unit 4 is detachably inserted into the quick-connect interface 31.

[0044] In this embodiment, the water outlet pipe 3 is equipped with a quick-release interface to enable the quick disassembly and assembly of the pressure detection unit 4, thereby enabling the quick replacement of the pressure detection unit 4.

[0045] In some embodiments, the pressure detection unit 4 is a ceramic pressure sensor.

[0046] In this embodiment, the pressure detection unit 4 can be a ceramic pressure sensor, which has the characteristics of corrosion resistance and high accuracy. When applied in the water softener, it can greatly improve the service life.

[0047] In some embodiments, the water softener also includes an alarm unit 8, which is electrically connected to the control unit 23.

[0048] In this embodiment, by setting up an alarm unit 8, when the pressure detection unit 4 detects an abnormal pressure and feeds it back to the control unit 23, the control unit 23 controls the alarm unit 8 to quickly sound an alarm, prompting the user to take timely action and avoid excessive water leakage causing property damage. The alarm unit 8 can be a buzzer, which promptly alerts the user by emitting a buzzing sound. Of course, when the alarm unit 8 sounds, the control unit 23 also promptly controls the valve 2 to close, achieving rapid water shut-off and thus reducing property damage caused by water leakage.

[0049] In some embodiments, the water softener further includes a display unit 9, which is electrically connected to the control unit 23.

[0050] In this embodiment of the application, by setting up a display unit 9, the specific fault conditions of the water softener can be displayed, which is convenient for timely response and handling of the faults.

[0051] Specifically, in this embodiment, when the alarm unit 8 sends an alarm signal to attract the user to the water softener, the corresponding fault information is displayed on the display unit 9, so that the user can understand the fault situation in time and thus take timely corresponding measures.

[0052] Accordingly, a water treatment system according to an embodiment of this application includes a water softener as described in any of the foregoing embodiments.
