[0033] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] In the embodiment of the utility model, the water purification device can guide the water flow into the filter element for filtration through the waterway plate, and output the filtered pure water through the waterway plate.

[0035] Combine the following Figures 1 to 4 , the waterway plate and water purification equipment provided in the embodiments of the present application are described in detail through specific examples.

[0036] Please also read Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a waterway plate provided in one embodiment of the utility model. Figure 2 It is a rear view of a waterway plate provided in one embodiment of the present invention. A waterway plate 100 provided in one embodiment of the present invention is applied to a water purification device 200. The waterway plate 100 includes a fixed plate 10, a water inlet pipe 20, a waste water pipe 30 and a three-way pipe 40. The water inlet pipe 20, the waste water pipe 30 and the three-way pipe 40 are all arranged on the fixed plate 10; wherein the three-way pipe 40 is connected to the water inlet pipe 20 and the filter element 50 of the water purification device 200 is connected to each other.

[0037] In this embodiment, the three-way pipe 40 can be used for the water inlet pipe 20 and the filter element 50. The pure water filtered in the filter element 50 can enter the three-way pipe 40, part of the pure water can be discharged through the three-way pipe 40 for use, and the other part can re-enter the water inlet pipe 20 through the three-way pipe 40, and then mix with the water flow in the water inlet pipe 20 and enter the filter element 50 again for filtration. The three-way pipe 40 can not only discharge the pure water, but also introduce part of the pure water into the water inlet pipe 20, so as to reflux part of the pure water. Through such a setting, pure water reflux can be achieved by only setting the three-way pipe 40, and there is no need to add a reflux pipe on the fixed plate 10, so that the structure of the waterway plate 100 is simpler and more compact.

[0038] It should be noted that the three-way pipe 40 and the water inlet pipe 20 can be integrally formed. By co-injection molding the three-way pipe 40 and the water inlet pipe 20, the process steps can be reduced and the time for splicing the three-way pipe 40 and the water inlet pipe 20 can be saved, thereby improving production efficiency.

[0039] In some embodiments, the three-way pipe 40 includes an outlet channel 41 and a return channel 42, the outlet channel 41 and the return channel 42 are connected; the outlet channel 41 is connected to the filter element 50 of the water purification equipment 200; the return channel 42 is connected to the water inlet pipe 20.

[0040] The water outlet channel 41 and the water inlet pipe 20 are both used to connect with the filter element 50, wherein the water inlet pipe 20 is used to introduce the external water flow into the filter element 50 for filtration, and the water outlet channel 41 is used to output the pure water obtained after filtration in the filter element 50. In the three-way pipe 40, the water outlet channel 41 and the return channel 42 are interconnected. When the water outlet channel 41 outputs the pure water in the filter element 50, part of the pure water is output for use (for example, drinking), and the other part can be diverted to the return channel 42.

[0041] In this embodiment, when too much pure water is introduced from the filter element 50 into the water outlet flow channel 41, the water pressure in the water outlet flow channel 41 will be too high, and the excessive water pressure may cause the water outlet flow channel 41 to rupture. By diverting part of the pure water to the backflow, the water pressure in the water outlet flow channel 41 can be reduced. With such a setting, the water outlet flow channel 41 can be prevented from rupture due to excessive water pressure, thereby extending the service life of the water outlet flow channel 41.

[0042] The reflux channel 42 is connected to the water inlet pipe 20. When part of the pure water in the outlet channel 41 is diverted to the reflux channel 42, the reflux channel 42 can guide the part of the pure water into the water inlet pipe 20. At this time, the water flow from the outside in the water inlet pipe 20 can be mixed with the pure water entering the water inlet pipe 20 from the reflux channel 42, and then continue to be introduced into the filter element 50 for the next filtration. Through such a setting, while the pure water is guided out of the outlet channel 41 to reduce the water pressure, the pure water and the water flow can also be mixed and filtered again, reducing the waste of water resources.

[0043] In some embodiments, a pressure relief valve (not shown) is disposed in the return flow channel 42 and is disposed toward the water inlet flow channel. The pressure relief valve is disposed in the return flow channel 42 and close to one end of the water outlet flow channel 41 .

[0044] In this embodiment, the pressure relief valve can control the water pressure in the outlet flow channel 41 by adjusting the flow of pure water. When the pressure on the pressure relief valve exceeds the set safety value, the pressure relief valve will automatically open and release the pure water into the return flow channel 42 to reduce the pressure of the outlet flow channel 41. When the water pressure is high, the pressure relief valve will open quickly, allowing the fluid pure water to flow through the pressure relief valve to the low-pressure area (return flow channel 42), thereby reducing the pressure in the outlet flow channel 41. Through such a setting, the pressure relief valve can reduce the water pressure of the outlet flow channel 41 by releasing part of the pure water in the outlet flow channel 41, thereby preventing the outlet flow channel 41 from rupturing. When the water pressure in the outlet flow channel 41 is low, the pressure relief valve will automatically close to limit the flow of pure water. Under low pressure conditions, the pressure relief valve reduces the outflow of pure water by closing the valve.

[0045] Specifically, the structure of the pressure relief valve includes a valve body, a valve cover, a valve core and a spring. The valve body is the main structure of the pressure relief valve, which is usually a tubular or cavity structure for accommodating other key components and connected to the outlet flow channel 41 and the return flow channel 42 respectively. The valve cover is used to seal the valve body and the valve core. The valve cover is usually connected to the valve body and ensures the sealing performance of the pressure relief valve through sealing materials such as sealing rings. The valve core is the main component that determines whether the valve is opened or closed. The valve core is usually cylindrical or conical, and the flow rate and pressure of the fluid can be controlled by adjusting the position of the valve core. The spring provides the force required when the valve core is closed to ensure the normal operation of the pressure relief valve. Usually, the spring is installed on the valve core or the valve cover, and the elastic force is used to keep the valve core closed. When the water pressure on the pressure relief valve exceeds the set safety value, the valve core will be opened by the pure water pressure. At this time, part of the pure water is released into the low-pressure area (outlet flow channel 41) through the channel in the valve body, thereby reducing the pressure in the outlet flow channel 41. When the pressure returns to a safe range, the spring closes the valve core to prevent pure water from flowing into the return flow channel 42. The opening pressure of the pressure relief valve can be changed by replacing or adjusting the stiffness, length or preload of the spring. Increasing the spring stiffness or preload can increase the opening pressure, while reducing the spring stiffness or preload can reduce the opening pressure.

[0046] In some embodiments, the three-way pipe 40 further includes a detection channel 43 , the detection channel 43 is connected to the water outlet channel 41 , and a water quality detector 431 is disposed on the detection channel 43 .

[0047] In this embodiment, the detection pipe is interconnected with the water outlet channel 41, and part of the pure water in the water outlet pipe can enter the detection channel. In addition, a water quality detector 431 is provided in the detection channel, and the water quality detector 431 can be used to detect the water quality of the pure water in the water outlet channel 41, thereby improving the safety of the water purification device 200.

[0048] Specifically, the TDS value of pure water can be detected by the water quality detector 431. It should be noted that the water quality detector 431 usually uses the conductivity measurement principle to detect the TDS value in the water flow. Conductivity refers to the resistance generated by the current passing through the conductive material in the water, which is proportional to the content of dissolved salts and other dissolved solid substances. The water quality detector 431 measures the conductivity and converts the conductivity into a corresponding TDS value in combination with a calibration curve. When the TDS value detected by the water quality detector 431 is low, the water quality is good; when the detected TDS value is high, the water quality is poor and contains more soluble solids.

[0049] In some embodiments, the water inlet pipe 20 includes a first water inlet pipe 21 and a second water inlet pipe 22 , the first water inlet pipe 21 and the second water inlet pipe 22 are connected through the booster pump 60 of the water purification equipment 200 , and the first water inlet pipe 21 is connected to the three-way pipe 40 .

[0050] The first water inlet pipe 21 is connected to the return flow channel 42 in the three-way pipe 40, and the pure water in the return flow channel 42 can be mixed with the water flow in the first water inlet pipe 21. And the first water inlet pipe 21 is connected to the second water inlet pipe 22 through the booster pump 60. The water flow in the first water inlet pipe 21 can be introduced into the booster pump 60, and after being pressurized in the booster pump 60, it is guided to the second water inlet pipe 22. The second water inlet pipe 22 is connected to the filter element 50, and the water flow after the pressurization treatment can enter the filter element 50 in the second water inlet pipe 22, so as to be filtered in the filter element 50.

[0051] If the water pressure of the water flow in the second water inlet pipe 22 is insufficient, the working effect of the filter element 50 may be weakened or completely ineffective. By increasing the pressure of the water flow through the booster pump 60, it can be ensured that the water flow can fully pass through the filter element 50 and be filtered. Specifically, by increasing the pressure of the water flow through the booster pump 60, the filtering effect of the filter element 50 on impurities, solid particles and dissolved substances in the water can be enhanced. Through such an arrangement, the pressurized water flow can better penetrate, rinse and clean the filter element 50, thereby improving the efficiency and quality of water purification.

[0052] In addition, the booster pump 60 can also balance the water pressure difference, helping the water purification device 200 to maintain stable operation under pressure fluctuations or load changes. By providing a stable water flow and pressure, the booster pump 60 helps to maintain the normal operation of the entire water purification device 200 and ensure the coordinated operation of various structures of the water purification device 200 (such as the filter element 50).

[0053] In some embodiments, the second water inlet pipe 22 is connected to the filter element 50 of the water purification device 200. The water flow in the second water inlet pipe 22 can enter the filter element 50 for filtration, thereby filtering and purifying the water flow. Specifically, after the water flow of the second water inlet pipe 22 is pushed into the filter element 50, the water flow can pass through the micropores and filter material of the filter element 50 to filter, adsorb and separate substances to purify the water quality.

[0054] In some embodiments, the fixing plate 10 is provided with a first water inlet 11, which is connected to the second water inlet pipe 22. The second water inlet pipe 22 is connected to the filter element 50 after passing through the first water inlet 11, so as to guide the water flow into the filter element 50 for filtering.

[0055] In some embodiments, the fixing plate 10 is further provided with a first water outlet 12, which is connected to the water outlet channel 41 of the three-way pipe 40. The water outlet channel 41 is provided through the first water outlet 12 and is connected to the filter element 50 to guide pure water into the three-way pipe 40.

[0056] In some embodiments, the fixing plate 10 is further provided with a first wastewater port 13, which is interconnected with the wastewater pipe 30. The wastewater pipe 30 is connected with the filter element 50 after passing through the first wastewater port 13, so as to guide wastewater into the wastewater pipe 30.

Through such a setting, pure water reflux can be achieved by only setting the three-way pipe 40, and there is no need to add a reflux pipe on the fixed plate 10, so that the structure of the waterway plate 100 is simpler and more compact.
