[0031] In the embodiment of the present utility model, the water purification device can filter the external water flow to obtain pure water for use.

[0032] Below in conjunction with Figures 1 to 4 , the water circuit structure and the water purification device provided by the embodiments of the present application will be described in detail through specific embodiments.

[0033] Please refer to Figure 1 and Figure 2 , Figure 1 It is a schematic structural diagram of a water purification device provided by one embodiment of the present utility model; Figure 2It is an assembly schematic diagram of a booster pump and a water circuit board provided by one embodiment of the present utility model. A water purification device 100 provided by one embodiment of the present utility model. The water purification device 100 includes a filter element 10, a water circuit board 20, and a booster pump 30. The filter element 10 is used to filter water flow; the water circuit board 20 includes a first water inlet pipe 21 and a second water inlet pipe 22. The first water inlet pipe 21 is communicated with an external water source, and the second water inlet pipe 22 is communicated with the filter element 10; one end of the booster pump 30 is connected to the first water inlet pipe 21, and the other end is connected to the second water inlet pipe 22; wherein, the flow of water into the filter element 10 can be controlled by controlling the switch of the booster pump 30.

[0034] Among them, the filter element 10 can filter suspended solids and particulate matters in the water flow. Through its specific filter material structure and pore size, the filter element 10 can effectively filter and capture suspended solids and particulate matters in the influent water. These suspended solids and particulate matters may include sediment, rust, sediment, etc. Through the filtering effect of the filter element 10, the influent water can become clear and transparent, removing visible impurities. And the filter materials in the filter element 10, such as activated carbon, etc., can adsorb and remove organic substances and odor substances in the water, such as residual chlorine, benzene, formaldehyde, etc. These organic substances and odor substances have an impact on the safety and taste of water. Through the adsorption effect of the filter element 10, the quality and taste of water can be improved. In addition, the filter element 10 also adopts technologies such as microporous membranes and ultrafiltration membranes to achieve the filtration and interception of bacteria and viruses. These microorganisms may exist in tap water, and these microorganisms pose a certain risk to human health. Through the microporous membrane or ultrafiltration membrane of the filter element 10, these microorganisms can be effectively removed, improving the hygienic safety of water. To sum up, through the filtering and purification effect of the filter element 10, impurities, odor substances, microorganisms, etc. in the water can be removed, improving the quality and safety of water.

[0035] The first water inlet pipe 21 and the second water inlet pipe 22 are arranged on the water circuit board 20. The first water inlet pipe 21 is used to connect with an external water source, and the external water source enters the first water inlet pipe 21. The second water inlet pipe 22 is connected to the filter element 10, and the water in the second water inlet pipe 22 can be introduced into the filter element 10 for purification and filtration.

[0036] The booster pump 30 can boost the water flow from the first water inlet pipe 21, and introduce the boosted water flow into the second water inlet pipe 22, and then introduce it into the filter element 10 through the second water inlet pipe 22, so that the boosted water flow can smoothly pass through the filter element 10, thereby achieving the purpose of purifying water quality.

[0037] In this embodiment, one end of the booster pump 30 is connected to a first water inlet pipe 21, and the other end is connected to a second water inlet pipe 22. After the booster pump 30 is turned on, the water flow in the first water inlet pipe 21 can enter the booster pump 30. Then, after being pressurized in the booster pump 30, the water flow can enter the second water inlet pipe 22 through the other end of the booster pump 30, and then enter the filter element 10 through the second water inlet pipe 22 for filtration. Moreover, after the booster pump 30 is turned off, the booster pump 30 does not pressurize the water flow, and the water flow in the first water inlet pipe 21 cannot enter the booster pump 30. At this time, the filter element 10 stops filtering and purifying the water flow. Through such a setting, only by providing the booster pump 30, it is possible to control whether the water flow enters the filter element 10 for filtration and purification operations, simplifying the internal structure of the water purification device 100.

[0038] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of the water circuit board provided by one embodiment of the present utility model. In some embodiments, the water circuit board 20 further includes an outlet water pipe 23, and the outlet water pipe 23 is communicated with the filter element 10, and the outlet water pipe 23 is used to export the purified water filtered by the filter element 10.

[0039] The outlet water pipe 23 is used to be connected to the filter element 10. When the pressurized water flow enters the filter element 10 through the second water inlet pipe 22, the filter element 10 can export the purified water obtained after filtration through the outlet water pipe 23. In this embodiment, only by providing the connection between the outlet water pipe 23 and the filter element 10, when the booster pump 30 is turned on, after the water flow passes through the filter element 10, the purified water obtained by filtration is exported to the outlet water pipe 23. When the booster pump 30 is turned off, the water flow no longer enters the filter element 10, and at this time, the amount of purified water exported from the filter element 10 to the outlet water pipe 23 decreases until there is no purified water exported. Through such a setting, the generation and export of purified water can be controlled by the booster pump 30, and there is no need to provide a valve on the outlet water pipe 23 to open or close the outlet water pipe 23, which can reduce the internal structure of the water purification device 100 to a certain extent, reduce production costs, and is simple to install.

[0040] In some embodiments, the water circuit board 20 further includes a waste water pipe 24, and the waste water pipe 24 is communicated with the filter element 10, and the waste water pipe 24 is used to export the waste water filtered by the filter element 10.

[0041] The wastewater pipe 24 is used to connect with the filter element 10. After the pressurized water flow enters the filter element 10 through the second water inlet pipe 22, the filter element 10 can export the wastewater generated after filtration through the wastewater pipe 24. In this embodiment, only by arranging the wastewater pipe 24 to be connected with the filter element 10, when the booster pump 30 is turned on, after the water flow passes through the filter element 10, the wastewater generated by filtration is exported to the wastewater pipe 24. When the booster pump 30 is turned off, the water flow no longer enters the filter element 10, and at this time, the wastewater exported from the filter element 10 decreases until there is no wastewater exported to the wastewater pipe 24. Through such a setting, the generation and export of wastewater can be controlled by the booster pump 30, without the need to set a valve on the wastewater pipe 24 to open or close the wastewater pipe 24, which can reduce the internal structure of the water purification device 100 to a certain extent, reduce the production cost, and is simple to install.

[0042] Please refer to Figure 4 , Figure 4 FIG. is a cross-sectional view of the filter element provided by one embodiment of the present invention. In some embodiments, the filter element 10 includes a filtering part 11, a first flow-through part 12 and a second flow-through part 13, and the first flow-through part 12, the filtering part 11 and the second flow-through part 13 are arranged at intervals from each other.

[0043] Among them, in the filter element 10, the first flow-through part 12 is arranged on the outermost layer, the filtering part 11 is arranged in the middle layer, and the second flow-through part 13 is arranged in the inner layer. When the external water flow enters the filter element 10, the water path first passes through the first flow-through part 12 and enters the filtering part 11 through the first flow-through part 12 for filtration, and the purified water obtained after filtration can enter the second flow-through part 13.

[0044] In this embodiment, the first flow-through part 12 can be a cavity for the water flow to flow. And when the water flow flows to the end in the first flow-through part 12, it can enter the filtering part 11 for filtration. Then, after the water flow in the filtering part 11 is filtered, it can enter the second flow-through part 13 wrapped by the filtering part 11 and flow to the outside of the filter element 10 through the second flow-through part 13.

[0045] It should be noted that the second flow-through part 13 can be a hollow pipe, and the filtering part 11 wraps this pipe. And, a plurality of through holes are opened on the outer periphery of the pipe, and the purified water filtered by the filtering part 11 can enter the second flow-through part 13 through the through holes.

[0046] Regarding the above-mentioned filtering part 11, the filtering part 11 includes pre-filter carbon and an RO filter element. The water flow first enters the pre-filter carbon through the first flow-through part 12, and then enters the RO filter element through the pre-filter carbon. After the water flow passes through the RO filter element, it can enter the second flow-through part 13. There is also post-filter carbon arranged in the second flow-through part 13, and purified water is obtained after passing through the post-filter carbon.

[0047] In some embodiments, the first flow-through portion 12 and the second water inlet pipe 22 communicate with each other.

[0048] In this embodiment, when the booster pump 30 pressurizes the water flow from the first water inlet pipe 21, the pressurized pump can introduce the pressurized water flow into the second water inlet pipe 22 and introduce it into the first flow-through portion 12 of the filter element 10 through the second water inlet pipe 22. Through such an arrangement, the water flow can enter the filter element 10 and flow in the filter element 10 for filtration and purification.

[0049] In some embodiments, the water outlet pipe 23 and the second flow-through portion 13 communicate with each other.

[0050] In this embodiment, the water outlet pipe 23 can be used to export the pure water filtered in the filter element 10. Specifically, after the filtration portion 11 filters the water flow, the pure water can enter the second flow-through portion 13 and flow in the second flow-through portion 13 and flow into the water outlet pipe 23. Through such an arrangement, the pure water in the filter element 10 can be exported to the water outlet pipe 23 and exported to the outside for use through the water outlet pipe 23.

[0051] In some embodiments, the wastewater pipe 24 and the filtration portion 11 communicate with each other.

[0052] The filtration portion 11 can filter the water flow. The pure water after filtration in the water path flows into the second flow-through portion 13, and the impurities in the water flow can be adsorbed in the filtration portion 11. At this time, the water flow can drive the adsorbed impurities in the filtration portion 11 into the wastewater pipe 24. Through such an arrangement, the wastewater can be exported to the wastewater pipe 24.

[0053] In some embodiments, the first water inlet pipe 21 and the water outlet pipe 23 are connected and communicate with each other.

[0054] The first water inlet pipe 21 and the water outlet pipe 23 are connected and communicate with each other. The pure water in the water outlet pipe 23 can be diverted into the first water inlet pipe 21. When too much pure water is introduced into the water outlet pipe 23 from the filter element 10, the water pressure in the water outlet pipe 23 will be too high. The too high water pressure may cause the water outlet pipe 23 to burst. After diverting part of the pure water into the first water inlet pipe 21, the water pressure in the water outlet pipe 23 can be reduced. Through such an arrangement, the water outlet pipe 23 can be prevented from bursting due to excessive water pressure, and the service life of the water outlet pipe 23 can be extended.

[0055] In some other examples, a pressure relief valve (not shown in the figure) is provided in the water outlet pipe 23, and the pressure relief valve is arranged facing the first water inlet pipe 21. The pressure relief valve can control the water pressure in the water outlet pipe 23 by adjusting the flow of pure water. Among them, when the pressure received by the pressure relief valve exceeds the set safety value, the pressure relief valve will automatically open, releasing the pure water into the first water inlet pipe 21 to reduce the pressure in the water outlet pipe 23. When the water pressure is high, the pressure relief valve will quickly open, allowing the pure water to flow through the pressure relief valve to the low-pressure area (the first water inlet pipe 21), thereby reducing the pressure in the water outlet pipe 23. Through such a setting, the pressure relief valve can reduce the water pressure in the water outlet pipe 23 by releasing some pure water in the water outlet pipe 23, preventing the water outlet pipe 23 from bursting. And when the water pressure in the water outlet pipe 23 is low, the pressure relief valve will automatically close to restrict the flow of pure water. In the low-pressure situation, the pressure relief valve reduces the outflow of pure water by closing the valve. Moreover, the above pressure relief valve is a one-way valve to allow the pure water in the water outlet pipe 23 to flow into the first water inlet pipe 21 and prohibit the water in the first water inlet pipe 21 from flowing into the water outlet pipe 23.

[0056] In some embodiments, the first water inlet pipe 21 includes a water inlet 211, and the water inlet 211 is used to communicate with an external water source, and a filter screen is arranged on the water inlet 211.

[0057] By arranging a filter screen at the water inlet 211 of the first water inlet pipe 21, large-particle impurities in the water can be filtered to a certain extent, thereby avoiding the risk that large-particle impurities enter the booster pump 30 following the water flow and causing the booster pump 30 to be blocked.

[0058] In some embodiments, the first water inlet pipe 21, the second water inlet pipe 22, the water outlet pipe 23, and the wastewater pipe 24 are integrally formed. By integrally injection-molding the first water inlet pipe 21, the second water inlet pipe 22, the water outlet pipe 23, and the wastewater pipe 24, it is possible to reduce the process steps and save the time for splicing pipes while improving production efficiency and reducing production costs.

[0059] It should be particularly noted that the water purification device 100 provided by the embodiment of the present invention only shows the part related to the technical problem to be solved by the embodiment of the present invention. It can be understood that the water purification device 100 provided by the embodiment of the present invention further includes other structures for realizing the functions of the water purification device 100, including but not limited to the housing for loading the water purification device, etc.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
