[0038] The present application will be described in detail below with reference to preferred embodiments and the accompanying drawings.

[0039] Reference is made to Figure 1This embodiment provides a water dispenser, including a water tank 1, a first solenoid valve 2, a filter module 3, a one-way valve 4, a second solenoid valve 5, a controller, and a water outlet 6. Both the first solenoid valve 2 and the second solenoid valve 5 are communicatively connected to the controller. The water tank 1 is provided with a first inlet and an outlet. The inlet of the first solenoid valve 2 is connected to the outlet of the water tank 1. The input end of the filter module 3 is connected to the outlet of the first solenoid valve 2, and the output end of the filter module 3 is connected to the inlet of the one-way valve 4. The outlet of the one-way valve 4 is connected to the first inlet. The inlet of the second solenoid valve 5 is connected to the outlet of the water tank 1, and the outlet of the second solenoid valve 5 is connected to the water outlet 6.

[0040] In practical applications, the aforementioned water dispenser can be a pipeline dispenser, specifically a wall-mounted pipeline water dispenser or a floor-standing pipeline water dispenser.

[0041] In this embodiment, the controller controls the opening and closing of the first solenoid valve 2 and the second solenoid valve 5, so that the water in the water tank 1 is filtered through the water outlet 6 or through the filter branch. Specifically, the controller controls the first solenoid valve 2 to open and the second solenoid valve 5 to close, so as to filter the water in the water tank 1 of the water dispenser and ensure the safety of the drinking water output to the water outlet 6. Specifically, the controller controls the first solenoid valve to close and the second solenoid valve 5 to open, so that the water in the water tank flows out through the water outlet 6.

[0042] In an optional implementation, see Figure 2 The filter module 3 includes a filter element assembly 31 and a first TDS meter 32; the first TDS meter 32 is communicatively connected to the controller; the inlet of the filter element assembly 31 is connected to the outlet of the first solenoid valve 2; the outlet of the filter element assembly 31 is connected to the inlet of the one-way valve 4 through the first TDS meter 32.

[0043] The first solenoid valve 2 and the second solenoid valve 5 are key components controlling whether water flows into the filter module 3. When the first solenoid valve 2 is open and the second solenoid valve 5 is closed, the water flows through the first solenoid valve 2 and then along the current filtration branch to the filter module 3. The filter module 3 includes a filter element assembly 31 and a first TDS meter 32. The filter element assembly 31 filters impurities from the water. Because the TDS meter measures the total dissolved solids in the water, the first TDS meter 32 monitors the TDS value of the water after filtration by the filter element assembly 31, thus determining whether the filtration effect meets the expected standards. Furthermore, the outlet of the filter element assembly 31 is connected to the inlet of the one-way valve 4 via the first TDS meter 32, ensuring that the filtered water flows only in one direction. This effectively prevents water from flowing back into the filter module 3, thus protecting the water quality from contamination.

[0044] In an optional embodiment, the filter element assembly 31 includes a first filter element and a second filter element; the inlet of the first filter element is connected to the outlet of the first solenoid valve 2; the outlet of the first filter element is connected to the inlet of the second filter element; and the outlet of the second filter element is connected to the first TDS meter 32.

[0045] Specifically, the filter element assembly 31 is a composite filter element, comprising two main parts: a first filter element and a second filter element. The first filter element, acting as a pre-filter, is connected to the outlet of the first solenoid valve to initially remove fine particles, organic matter, residual chlorine, and odors from the water. The second filter element, acting as a post-filter, has its inlet connected to the outlet of the first filter element. Ultimately, the water filtered by the filter element assembly 31 is discharged through the first TDS meter 32. The second filter element primarily handles further purification of the water at both physical and chemical levels. In a specific example, the first filter element can be a composite of polypropylene meltblown and activated carbon, or a carbon fiber filter element, or a composite of polypropylene meltblown and carbon rods. These materials effectively perform initial filtration, laying a good foundation for subsequent fine filtration. Depending on more detailed purification needs, the second filter element can be a carbon rod filter element, a granular activated carbon filter element, or a composite of carbon rods and ultrafiltration membranes. These filter elements will perform deep treatment of the water through physical interception and chemical adsorption, ensuring that the water quality reaches higher standards. This design allows the entire filter assembly 31 to progressively clean various impurities in the water, thereby ensuring the purity of the water and meeting different usage needs.

[0046] In an optional implementation, see Figure 2 The filter module 3 also includes a sterilization device 7; one end of the sterilization device 7 is connected to the outlet of the filter element assembly 31, and the other end of the sterilization device 7 is connected to the first TDS meter 32.

[0047] Specifically, such as Figure 2 As shown, the sterilization device 7 is used to further improve water quality. The sterilization device 7 typically employs ultraviolet (UV) lamps or chlorination treatment, methods that effectively kill bacteria, viruses, and other microorganisms that may be present in the water, thus ensuring the biological safety of the water. Placing the sterilization device 7 between the filter cartridge assembly 31 and the first TDS meter 32 maximizes the protection of the first TDS meter 32 from biological contamination, while ensuring that the water flowing from the filter module 3 is sterile, suitable for direct drinking or other applications with strict hygiene requirements. The addition of the sterilization device 7 enables the entire filter module 3 to not only remove impurities from the water but also ensure the microbial safety of the water, providing a more comprehensive water purification solution.

[0048] In an optional implementation, see Figure 2The filter module 3 also includes a booster pump 8; the inlet of the booster pump 8 is connected to the outlet of the first solenoid valve 2, and the outlet of the booster pump 8 is connected to the inlet of the filter element assembly 31.

[0049] Specifically, such as Figure 2 As shown, the booster pump 8 plays a crucial role in the branch purification and filtration of the water dispenser. Its inlet is directly connected to the outlet of the first solenoid valve 2, and its outlet is connected to the inlet of the filter element assembly 31. When the first solenoid valve 2 is open and the second solenoid valve 5 is closed, water flows through the first solenoid valve 2 and into the booster pump 8. The booster pump 8 increases the water pressure, which further promotes the effective flow of water through the filter element material. This is essential for ensuring the efficiency of the water purification system, as the materials used for filtration in the filter element assembly 31, such as activated carbon and ultrafiltration membranes, may create resistance to the water flow. The additional pressure generated by the booster pump 8 can, to some extent, offset this resistance. Furthermore, the design of the booster pump 8 also considers the overall energy efficiency and performance of the system. During the purification process, appropriate pressure not only accelerates the filtration process but also helps to remove impurities from the water more thoroughly. Especially when dealing with low water pressure or high water demand, it can significantly improve the filtration efficiency and water quality of the entire system.

[0050] In an optional implementation, see Figure 2 The water dispenser also includes a temperature control module 9 that is communicatively connected to the controller; the input end of the temperature control module 9 is connected to the outlet of the second solenoid valve 5, and the output end of the temperature control module 9 is connected to the water outlet 6.

[0051] Specifically, such as Figure 2 As shown, the water dispenser includes a temperature control module 9, which can precisely adjust the water temperature according to user settings or preset programs to meet different drinking needs. When the second solenoid valve 5 opens and the first solenoid valve 2 closes, water from the water tank flows into the temperature control module 9, which can quickly respond and achieve instant temperature adjustment. The input end of the temperature control module 9 is connected to the outlet of the second solenoid valve 5, ensuring smooth water flow and continuous temperature adjustment. The output end of the temperature control module 9 is directly connected to the water spout 6, allowing users to conveniently obtain drinking water at a suitable temperature.

[0052] In an optional implementation, see Figure 3The temperature control module 9 includes a first temperature sensor 91, a second temperature sensor 92, and a heating element 93. One end of the first temperature sensor 91 is connected to the outlet of the second solenoid valve 5, and the other end of the first temperature sensor 91 is connected to the input end of the heating element 93. The first temperature sensor 91 is used to detect the first temperature at the input end of the heating element 93. One end of the second temperature sensor 92 is connected to the output end of the heating element 93, and the other end of the second temperature sensor 92 is connected to the water outlet 6. The second temperature sensor 92 is used to detect the second temperature at the output end of the heating element 93.

[0053] Specifically, such as Figure 3 As shown, the first temperature sensor 91 and the second temperature sensor 92 monitor the water temperature before and after heating, ensuring that the temperature control module 9 can monitor the water temperature changes in real time. The first temperature sensor 91 detects the water temperature before it enters the heating element 93, providing initial temperature data for the temperature control module 9; the second temperature sensor 92 detects the water temperature after it is heated by the heating element 93, ensuring that the outlet water temperature meets the user's setting. In the temperature control module 9, the heating element 93, as the core component, is responsible for heating the water to the ideal temperature set by the user based on the first temperature measured by the first temperature sensor 91 and the second temperature measured by the second temperature sensor 92. The efficiency and accuracy of the heating element 93 directly affect the quality and speed of water temperature regulation. Through the precise monitoring of the first temperature sensor 91 and the second temperature sensor 92 and the intelligent adjustment of the heating element 93, the user can set a suitable drinking water temperature according to their needs.

[0054] In a specific example, an incremental PID algorithm is used to adjust the power of the heating element. If the PID calculation result is positive, it indicates that the current temperature is lower than the set temperature, and the heating element 93 is controlled to increase its power, thereby raising the outlet water temperature. If the PID calculation result is negative, it indicates that the current temperature is higher than the set temperature, and the heating element 93 needs to be controlled to decrease its power, thereby lowering the outlet water temperature. Specifically, if the user sets the outlet water temperature to 55 degrees Celsius, the first solenoid valve 2 of the water dispenser is closed, the second solenoid valve 5 is open, the first temperature sensor 91 detects the temperature T1 at the outlet of the water tank 1, the heating element heats the flowing water, and then the second temperature sensor 92 detects the heated water temperature T2. If T2 is lower than the user-set 55 degrees Celsius, the heating element 93 will adjust its working power according to the values ​​of T1 and T2 using the PID algorithm. The heating element 93 will continuously adjust its power until the outlet water temperature stabilizes at the user-set 55 degrees Celsius. At this point, the heating element 93 will maintain a constant working power to maintain a stable outlet water temperature of 55 degrees Celsius.

[0055] In another alternative implementation, the temperature control module 9 can also cool the drinking water, lowering its temperature to the set outlet temperature via a cooling device within the module. In a specific example, when the user sets the outlet temperature to 3 degrees Celsius (ice water), if the first temperature sensor 91 detects a temperature T1 at the outlet of water tank 1 higher than 3 degrees Celsius, the cooling device in the temperature control module 9 is adjusted to lower the water temperature until the water temperature T2 detected by the second temperature sensor 92 drops to 3 degrees Celsius.

[0056] In an optional implementation, see Figure 2 The water dispenser also includes a second TDS meter 10 that is communicatively connected to the controller; the outlet of the water tank 1 is connected to the inlet of the first solenoid valve through the second TDS meter 10; the outlet of the water tank 1 is connected to the inlet of the second solenoid valve 5 through the second TDS meter 10.

[0057] Specifically, the outlet of water tank 1 is connected to the inlet of the first solenoid valve 2 via the second TDS meter 10, and is also connected to the inlet of the second solenoid valve 5 via the second TDS meter 10. The setting of the second TDS meter 10 enables the monitoring of drinking water quality before water is discharged, regardless of whether the water in water tank 1 flows directly to the filter module 3 for purification via the first solenoid valve 2 or flows to the temperature control module 9 for temperature adjustment via the second solenoid valve 5.

[0058] In a specific example, an incremental PID algorithm is used to calculate the working time of the filtration mode and the working intensity of the booster pump. If the PID calculation result is positive, it indicates that the opening time of the first solenoid valve 2 needs to be increased, which means increasing the working time of the filter module 3, or increasing the working intensity of the booster pump 8 to increase the filtration speed. If the PID calculation result is negative, the opening time of the first solenoid valve 2 needs to be reduced, the working time of the filter module 3 needs to be reduced, and the working intensity of the booster pump 8 needs to be weakened to reduce the filtration speed. Specifically, the preset safe TDS value is 50 mg / L. When the second TDS meter 10 detects a TDS value exceeding 50 mg / L, it will immediately start the filtration mode. At this time, the first solenoid valve 2 opens, allowing water to flow into the filter module 3, while the second solenoid valve 5 closes to ensure that unfiltered water does not flow out directly. Based on the TDS value detected by the second TDS meter 10, the PID algorithm is used for calculation. If the calculation result is positive, the working time of the filtration mode is increased, and the working intensity of the booster pump 8 is increased to ensure that the TDS value can be effectively reduced to below 50 mg / L under different pollution levels.

[0059] In another specific example, the water dispenser can be intelligently set to automatically filter the water in the tank at set time intervals. For instance, if the time interval is set to 6 hours, the dispenser will automatically activate the second TDS meter 10 every 6 hours to perform a test. If the detected TDS value does not meet the standard, it indicates that the impurity content in the water may exceed the standard for healthy drinking water. At this time, the first solenoid valve 2 is opened, and the water in the tank 1 is purified through the filter module 3 to remove excess impurities. Through timed detection, it is possible to promptly detect whether the TDS value in the tank 1 has reached the preset standard. For water dispensers that are not used for a long time, the water in the tank 1 may remain stagnant for an extended period, which may lead to gradual deterioration of water quality. Therefore, even if the water dispenser is not used for a long time, timed detection and filtration can effectively prevent water quality problems and ensure the quality of drinking water.

[0060] In an optional implementation, see Figure 2 The water dispenser also includes a third solenoid valve 11 that is communicatively connected to the controller; the water tank 1 is provided with a second water inlet; the outlet of the third solenoid valve 11 is connected to the second water inlet.

[0061] Specifically, by introducing a third solenoid valve 11 and setting a second water inlet for the water tank 1, the water dispenser can achieve automatic water filling, greatly improving its ease of use. The third solenoid valve 11 controls the connection between the external water source and the water tank 1 inside the dispenser. One end of the third solenoid valve 11 can be directly connected to a household tap water pipe or other water source, while the other end is connected to the second water inlet of the water tank 1. When the water level in the water tank 1 is lower than the preset safe water level, the controller automatically opens the third solenoid valve 11, allowing water to flow into the water tank 1 for automatic replenishment. When the water level in the water tank 1 reaches the preset height, the controller closes the third solenoid valve 11, stopping the water flow. In this way, the water dispenser can achieve unattended automatic water filling, ensuring that the water tank 1 always has a sufficient water supply, thus avoiding the inconvenience of frequent manual refilling.

[0062] In specific implementation, the communication connection between the controller and the first solenoid valve, the second solenoid valve, the third solenoid valve, the temperature control module, the first TDS meter, and the second TDS meter can be a wired connection, such as transmitting control signals through an electrical connection, or a wireless connection, such as transmitting control signals wirelessly.

[0063] In a specific example, see Figure 2The water dispenser integrates all components, including water tank 1, first solenoid valve 2, filter module 3, one-way valve 4, second solenoid valve 5, water outlet 6, sterilization device 7, booster pump 8, temperature control module 9, second TDS meter 10, and third solenoid valve 11, into one unit. It fully considers the high requirements of modern families for drinking water quality, convenience, and space utilization. By integrating filtration function, drinking water temperature adjustment function, and automatic water replenishment function of water tank 1, it can provide high-quality drinking water in different usage scenarios and meet various user needs.

[0064] In an optional implementation, see Figure 4 The water dispenser also includes a filter holder 12; the filter assembly 31 is disposed on the filter holder 12.

[0065] Specifically, such as Figure 4 As shown, the filter holder 12 is designed according to the size and shape of the filter assembly 31, ensuring that the filter assembly 31 can be securely installed inside the water dispenser. This not only facilitates the replacement of the filter assembly 31 but also ensures that water passes evenly through the filter assembly 31 during the filtration process. The filter holder 12 is typically made of food-grade safe materials, such as stainless steel or non-toxic plastic. These materials will not cause secondary pollution to the water quality, ensuring the safety of drinking water. Users can easily replace the filter themselves according to the replacement instructions provided by the water dispenser, without the need for professional tools or technicians.

[0066] In a specific example, such as Figure 4 As shown, a water collection box 13 is also provided below the water outlet 6 of the water dispenser. When the user uses the water dispenser to get water, water may splash out or overflow during operation. The water collection box 13 can catch these overflowing water, preventing them from splashing directly onto the ground or countertop, thereby reducing cleaning work and potential slip risks.
