Referring to Figures 1 to 22, this application embodiment provides a water purification device 10, which is used to filter tap water and remove harmful substances from the tap water, thereby ensuring the safety of drinking water. This water purification device 10 is applicable to various places with water purification needs.

In some embodiments, referring to Figures 1 to 3, 14, 15, and 22, the water purification device 10 includes a filtration module for treating water. The filtration module includes an ultrafiltration module 20, which includes an ultrafiltration filter element 21. The ultrafiltration membrane in the ultrafiltration filter element 21 can efficiently filter the raw water (water just entering the water purification device 10) to obtain ultrafiltered water. After treatment by the ultrafiltration filter element 21, the raw water... Most of the silt, rust, suspended solids, and colloids can be filtered out, thus ensuring the safety of the water quality.

In some embodiments, referring to Figures 1 to 3 and Figure 22, the ultrafiltration module 20 may further include a pretreatment filter element 22. Along the flow direction of the raw water, the pretreatment filter element 22 may be located upstream of the ultrafiltration filter element 21. The pretreatment filter element 22 can pretreat the raw water, including but not limited to removing coarse particulate impurities, silt, and organic pollutants from the raw water. Water filtered by the pretreatment filter element 22 then flows into the ultrafiltration filter element 21 for filtration, which can reduce the filtration pressure of the ultrafiltration filter element 21 and help improve its service life.

This application does not limit the specific selection of the pretreatment filter element 22. In some embodiments, the pretreatment filter element 22 can be a PP cotton filter element (Polypropylene meltblown filter element), which is a high-density fiber cotton filter element capable of filtering out larger particulate impurities; or, the pretreatment filter element 22 can be a GAC filter element (Granular Activated Carbon Filter), which can effectively remove small molecule organic matter and residual chlorine in the water and adsorb discoloration and odor in the water. When the pretreatment filter element 22 includes both a PP cotton filter element and a GAC filter element, the PP cotton filter element can be located upstream of the GAC filter element along the water flow direction. In some embodiments of this application, the pretreatment filter element 22 can be a composite filter element, which simultaneously possesses the functions of a PP cotton filter element and a GAC filter element, and can achieve pretreatment of raw water.

In some embodiments, referring to Figures 1 to 3, 5 to 7, 14 to 16 and 18, the filtration module further includes a reverse osmosis module 30, which includes a reverse osmosis filter element 31. Along the direction of water flow, the reverse osmosis filter element 31 can be located downstream of the ultrafiltration filter element 21. The ultrafiltration water treated by the ultrafiltration filter element 21 can flow into the reverse osmosis filter element 31 for reverse osmosis treatment to obtain pure water.

In some embodiments, referring to Figures 1 to 3, as well as Figures 9, 17 and 18, the reverse osmosis module 30 may further include a drive member 32 connected to the reverse osmosis filter element 31, the drive member 32 being used to increase the pressure of the water flowing into the reverse osmosis filter element 31.

This application does not limit the specific selection of the driving component 32. In some embodiments, the driving component 32 can be a motor, a booster pump, etc.

This application does not specifically limit the number of filter elements and drive components 32 in the water purification device 10. In some embodiments, the number of ultrafiltration filter element 21 and pretreatment filter element 22 can both be one. The pretreatment filter element 22 can be a composite filter element, and ultrafiltration water can be obtained after treatment by the composite filter element and the ultrafiltration filter element 21. The number of reverse osmosis filter elements 31 can be multiple. Multiple reverse osmosis filter elements 31 can accelerate the reverse osmosis treatment efficiency of the water purification device 10. The number of drive components 32 can be the same as the number of reverse osmosis filter elements 31 and be set one-to-one to pressurize the water flowing into the corresponding reverse osmosis filter element 31. In some examples of this application, referring to Figures 1 to 3 and Figures 17 and 18, the number of reverse osmosis filter elements 31 can be two. Pure water can be obtained after treatment by the reverse osmosis filter elements 31. The number of drive components 32 can also be two, and the two drive components 32 are set corresponding to the two reverse osmosis filter elements 31.

In some embodiments, referring to Figures 13, 15 and 21, the water purification device 10 further includes a water storage module 310, which includes a pressure tank 311 connected to at least one of the ultrafiltration module 20 and the reverse osmosis module 30, and the pressure tank 311 is used for water storage.

In the above embodiments, referring to Figure 22, the pressure tank 311 can be connected only to the ultrafiltration module 20 or the reverse osmosis module 30, that is, the pressure tank 311 can be connected to the water outlet of the ultrafiltration filter element 21 or the water outlet of the reverse osmosis filter element 31; when the pressure tank 311 is connected to the water outlet of the ultrafiltration filter element 21, the pressure tank 311 stores ultrafiltration water; when the pressure tank 311 is connected to the water outlet of the reverse osmosis filter element 31, the pressure tank 311 stores pure water. The ultrafiltration membrane of the ultrafiltration filter element 21 can intercept harmful substances such as sediment, colloids, and organic matter in the water. The reverse osmosis membrane of the reverse osmosis filter element 31 has a high filtration accuracy, typically below 0.0001 microns, which can filter out even smaller molecules in the water. Therefore, for areas with good water quality, the water purification device 10 may include a water storage module 310, and one of the ultrafiltration module 20 and the reverse osmosis module 30. Preferably, based on considerations of operating costs and beneficial minerals in the water, the water purification device 10 may include a water storage module 310 and an ultrafiltration module 20. For areas with poor water quality, the water purification device 10 may simultaneously include an ultrafiltration module 20, a reverse osmosis module 30, and a water storage module 310 to achieve multiple treatments of the raw water, which is beneficial to ensuring drinking water safety.

In an embodiment where the water purification device 10 includes an ultrafiltration module 20, a reverse osmosis module 30, and a water storage module 310, the pressure tank 311 can be connected to both the ultrafiltration module 20 and the reverse osmosis module 30 simultaneously. Specifically, the pressure tank 311 can be connected to both the outlet of the ultrafiltration filter element 21 of the ultrafiltration module 20 and the outlet of the reverse osmosis filter element 31 of the reverse osmosis module 30. Users can open either the first channel between the ultrafiltration filter element 21 and the pressure tank 311, or the second channel between the reverse osmosis filter element 31 and the pressure tank 311, as needed. For example, when the water quality is good, the user can open the first channel and shut off the second channel, meaning the raw water will be pretreated and ultrafiltered to obtain relatively pure water. When the water quality is poor, the user can open the second channel and shut off the first channel, meaning the raw water will be pretreated and ultrafiltered to obtain ultrafiltered water, which will then flow into the reverse osmosis filter element 31 for reverse osmosis treatment, thus obtaining relatively pure water.

In some embodiments, the ultrafiltration module 20, reverse osmosis module 30 and water storage module 310 of the water purification device 10 may have at least three arrangement methods. The first arrangement method may be: the ultrafiltration module 20, reverse osmosis module 30 and water storage module 310 are integrated into the same device. Referring to Figures 1 to 3, as well as Figures 13 and 14, the second arrangement can be: the ultrafiltration module 20 and the reverse osmosis module 30 are integrated into the same device, and the water storage module 310 is a separate device; referring to Figure 15, the third arrangement can be: the ultrafiltration module 20, the reverse osmosis module 30, and the water storage module 310 are each a separate device.

Referring to Figures 1 to 3, as well as Figures 13 and 14, the second arrangement is illustrated as an example, where the ultrafiltration module 20 and the reverse osmosis module 30 are integrated into the same device, while the water storage module 310 is a separate device. In this case, the device containing the ultrafiltration module 20 and the reverse osmosis module 30 can be connected to the device containing the water storage module 310 using a flexible hose. To improve the space utilization of the water purification equipment 10, the pretreatment filter element 22 and the ultrafiltration filter element 21 can be arranged in parallel, multiple reverse osmosis filter elements 31 can be arranged in parallel, and multiple drive components 32 can also be arranged in parallel, thereby contributing to a compact structure for the water purification equipment 10.

In some embodiments of this application, the filter elements (pretreatment filter element 22 and ultrafiltration filter element 21) of the ultrafiltration module 20 can be intersected with the reverse osmosis filter element 31 and the drive element 32 of the reverse osmosis module 30. Optionally, referring to Figures 1 to 3, the pretreatment filter element 22 and the ultrafiltration filter element 21 can be respectively extended along the first direction Z, and the reverse osmosis filter element 31 and the drive element 32 can be respectively extended along the second direction X or the third direction Y. The second direction X and the third direction Y intersect with the first direction Z, and the second direction X and the third direction Y intersect with each other. The intersecting arrangement of the ultrafiltration module 20 and the reverse osmosis module 30 can, to a certain extent, make the internal structure of the water purification device 10 more compact, which is beneficial to improving the utilization rate of the internal space of the water purification device 10. The reverse osmosis filter element 31 and the drive element 32 can be parallel to each other. The two reverse osmosis filter elements 31 can be arranged at intervals along the first direction Z, and the two drive elements 32 can also be arranged at intervals along the first direction Z, thereby reducing the area occupied by the reverse osmosis filter element 31 and the drive element 32 on the first plane, which is the plane containing the second direction X and the third direction Y.

In the above embodiment, the first direction Z, the second direction X, and the third direction Y are perpendicular to each other. The first direction Z can be the height direction of the water purification device 10, the second direction X can be the length direction of the water purification device 10, the third direction Y can be the width direction of the water purification device 10, and the first plane can be a horizontal plane.

In some embodiments, referring to FIG22, the water purification device 10 may further include a water circuit structure 400, which connects the water storage module 310 and at least one of the ultrafiltration module 20 and the reverse osmosis module 30, thereby enabling the water purification process of the water purification device 10. The water circuit structure 400 may be equipped with multiple valves, the arrangement of which will be specifically described in the section on the water circuit structure 400 below, and will not be repeated here.

Taking the second arrangement as an example, in some embodiments, referring to Figures 1 to 3, the water purification device 10 may include a first housing 100 and a partition component 110 disposed within the first housing 100. The partition component 110 includes a first partition plate 111 and a second partition plate 112 that are inclined. The first partition plate 111 can be a load-bearing plate 1, and the second partition plate 112 can be a hanging plate 2. An ultrafiltration module 20 and a reverse osmosis module 30 may be integrated inside the first housing 100. The hanging plate 2 and the load-bearing plate 1 can be inclined to each other. The inner wall of the first housing 100, the hanging plate 2, and the load-bearing plate 1 can jointly enclose at least three regions, namely a first region 4 for accommodating the ultrafiltration module 20, a second region 5 for accommodating the reverse osmosis module 30, and a third region 6. At least two of the first region 4, the second region 5, and the third region 6 are arranged at intervals along the first direction Z, thereby reducing the floor area of the water purification device 10 and making the internal structure of the water purification device 10 more compact, which is beneficial to improving the utilization rate of the internal space of the water purification device 10. The reverse osmosis filter element 31 of the reverse osmosis module 30 can be located in the second region 5, and the drive component 32 of the reverse osmosis module 30 can be located in the third region 6. By setting the first partition plate 111 and the second partition plate 112, the internal space of the first housing 100 can be reasonably divided, which can reduce the floor space of the water purification equipment 10 to a certain extent and improve the utilization rate of the internal space of the water purification equipment 10.

In some embodiments, referring to Figures 1 to 3, the load-bearing plate 1 can be connected to the inner wall of the first housing 100. The load-bearing plate 1 can divide the internal space of the first housing 100 into two regions distributed in the first direction Z. The hanging plate 2 is connected to the inner wall of the first housing 100 and is inclinedly connected to the load-bearing plate 1. The arrangement of the hanging plate 2 can further divide one of the two regions distributed in the first direction Z into two regions, thereby forming the aforementioned first region 4, second region 5 and third region 6.

In some embodiments of this application, the filter element of the ultrafiltration module 20 can be disposed on one side of the load-bearing plate 1, and the reverse osmosis filter element 31 and the drive element 32 of the reverse osmosis module 30 can be disposed on the other side of the load-bearing plate 1. Meanwhile, in order to better divide the area within the first housing 100, the reverse osmosis filter element 31 and the drive element 32 can be respectively located in two areas further formed by the addition of the hanging plate 2, that is, the reverse osmosis filter element 31 and the drive element 32 can be respectively located in the second area 5 and the third area 6, and the pretreatment filter element 22 and the ultrafiltration filter element 21 of the ultrafiltration module 20 can be located in the first area 4. Since the ultrafiltration module 20 includes a pretreatment filter element 22 and an ultrafiltration filter element 21, and its weight is relatively large, in some embodiments, referring to Figures 1 to 3, the first region 4 can be closer to the ground than the second region 5 and the third region 6, in order to consider the overall weight of the ultrafiltration module 20 and the reverse osmosis module 30. Accordingly, the ultrafiltration module 20 can be located at the lower part of the first housing 100, so that the reverse osmosis filter element 31 and the drive unit 32 can be located at the upper part of the first housing 100, that is, the second region 5 and the third region 6 are located at the upper part of the first housing 100.

In the above embodiments, referring to Figures 1 to 3, the load-bearing plate 1 can be parallel to the first plane, and the hanging plate 2 and the load-bearing plate 1 can be arranged perpendicular to each other, so that the internal space of the first housing 100 can be divided more regularly, and the structural strength of the water purification equipment 10 can be improved to a certain extent.

In some embodiments, the first housing 100, the hanging plate 2, and the load-bearing plate 1 can all be detachably connected, which facilitates the re-division of the size of the three areas and also facilitates the maintenance or replacement of the hanging plate 2 and the load-bearing plate 1.

In some embodiments, the load-bearing plate 1 and the mounting plate 2 may be provided with a plurality of mounting holes 124. The mounting holes 124 can be used to install various valves, various pipes, or various valves and pipes in the water circuit structure 400. For example, the mounting holes 124 can be used to install inlet valves, wastewater valves, etc. The mounting holes 124 may also be connected to mounting plates 122. The mounting plates 122 are used to install various valves, various pipes, or various valves and pipes.

Referring to Figure 22, the water circuit structure 400 of the water purification device 10 will be described next. Among them, "JS" refers to the water inlet of the water purification device 10, "CS" refers to the water outlet of the water purification device 10, and "FS" refers to the wastewater outlet of the water purification device 10.

In some embodiments, the water circuit structure 400 includes an inlet water circuit 401, a first outlet water circuit 402, and a first wastewater circuit 403 connected to the ultrafiltration module 20. The inlet end of the inlet water circuit 401 is connected to JS, and the outlet end of the inlet water circuit 401 is connected to the inlet end of the ultrafiltration module 20. The inlet end of the first outlet water circuit 402 is connected to the outlet end of the ultrafiltration module 20 and can be connected to the water storage module 310. The inlet end of the first wastewater circuit 403 is connected to the wastewater end of the ultrafiltration module 20, and the outlet end of the first wastewater circuit 403 is connected to FS for discharging wastewater. Raw water can flow from the inlet water circuit 401 to the ultrafiltration module 20. After the ultrafiltration module 20 performs ultrafiltration treatment on the raw water, the wastewater can be discharged from the first wastewater circuit 403, and the filtered ultrafiltration water can be drawn out through the first outlet water circuit 402.

In an embodiment where the ultrafiltration module 20 includes an ultrafiltration filter element 21, referring to Figure 22, the inlet water passage 401, the first outlet water passage 402, and the first wastewater passage 403 are respectively connected to the ultrafiltration filter element 21. In an embodiment where the ultrafiltration module 20 includes an ultrafiltration filter element 21 and a pretreatment filter element 22, the pretreatment filter element 22 is located upstream of the ultrafiltration filter element 21 along the flow direction of the raw water. The water pretreated by the pretreatment filter element 22 then flows to the ultrafiltration filter element 21, which can reduce the filtration pressure of the ultrafiltration filter element 21.

In some embodiments, referring to FIG22, the water circuit structure 400 includes a second outlet water circuit 404, a confluence water circuit 405, and a second wastewater water circuit 406. The inlet end of the second outlet water circuit 404 is connected to the outlet end of the ultrafiltration filter element 21, and the outlet end of the second outlet water circuit 404 is connected to the inlet end of the reverse osmosis module 30. The inlet end of the confluence water circuit 405 is connected to the outlet end of the reverse osmosis module 30, and the outlet end of the confluence water circuit 405 is connected to the inlet end of the water storage module 310. The inlet end of the second wastewater water circuit 406 is connected to the wastewater end of the reverse osmosis module 30, and the outlet end of the second wastewater water circuit 406 is connected to FS for discharging wastewater. The ultrafiltration water obtained after treatment by the ultrafiltration filter element 21 can flow to the reverse osmosis module 30 for reverse osmosis treatment, thereby obtaining pure water.

In the above embodiment, referring to Figure 22, since the inlet ends of the first water outlet path 402 and the second water outlet path 404 can be connected to the outlet end of the same ultrafiltration filter element 21, the first water outlet path 402 can directly lead out the ultrafiltration water, and the second water outlet path 404 can lead the ultrafiltration water to the reverse osmosis module 30 for reverse osmosis treatment. By connecting different water outlet paths, the user can perform different treatments on the raw water. The water circuit structure 400 can satisfy both the scheme of only the ultrafiltration module 20 and the scheme of the combination of the ultrafiltration module 20 and the reverse osmosis module 30, which can realize modular design and improve the versatility of the water purification equipment 10.

In some embodiments, the control component may include a solenoid valve assembly, which may include a first solenoid valve (not shown) and a second solenoid valve (not shown). The first solenoid valve may be located in the first water outlet passage 402, and the second solenoid valve may be located in the second water outlet passage 404. The first circuit board 141 can control the operating state of the first and second solenoid valves to ensure that the first water outlet passage 402 or the second water outlet passage 404 is in a conductive state. When the first water outlet passage 402 is in a conductive state and the second water outlet passage 404 is in a cut-off state, the water storage module 310 can store ultrafiltration water; when the second water outlet passage 404 is in a conductive state and the first water outlet passage 402 is in a cut-off state, the water storage module 310 can store pure water.

In the above embodiments, the first solenoid valve and the second solenoid valve can also be replaced with mechanical valves, thereby reducing the manufacturing cost and operating cost of the water purification equipment 10.

In the embodiment of the reverse osmosis module 30 including the reverse osmosis filter element 31 and the drive element 32, referring to FIG22, the drive element 32 can be located upstream of the reverse osmosis filter element 31. The ultrafiltration water in the second outlet water channel 404 is pressurized by the drive element 32 and can be transported to the reverse osmosis filter element 31 for filtration. The filtered pure water flows into the confluence water channel 405, and the filtered wastewater flows to the second wastewater channel 406.

In some embodiments, referring to FIG22, the water channel structure 400 may further include a confluence branch 407, the inlet of which is connected to the outlet of the ultrafiltration filter element 21, and the outlet of which is connected to the inlet of the confluence water channel 405. This allows ultrafiltration water and pure water to be mixed in the confluence water channel 405. Since the ultrafiltration membrane of the ultrafiltration filter element 21 retains most of the minerals in the water during filtration, but the reverse osmosis membrane of the reverse osmosis filter element 31 easily filters out beneficial minerals and trace elements, mixing ultrafiltration water and pure water yields mixed water with a certain amount of soluble minerals, resulting in drinking water with a better taste. In some embodiments of this application, the pressure tank 311 of the water storage module 310 can be used to store the mixed water with a better taste.

In the above embodiment, referring to FIG22, the inlet of the confluence branch 407 can be located between the drive unit 32 and the reverse osmosis filter element 31, that is, the drive unit 32 can also pressurize the ultrafiltration water flowing to the confluence branch 407.

Correspondingly, the number of second outlet water channels 404, confluence branch channels 407, and second wastewater channels 406 can also be multiple. The inlet ends of multiple second outlet water channels 404 can be integrated into one end, thereby facilitating the connection between multiple second outlet water channels 404 and ultrafiltration filter elements 21. The arrangement of multiple second outlet water channels 404 enables ultrafiltration water to undergo multiple parallel reverse osmosis filtrations, which is beneficial to improving the water treatment speed and increasing the water treatment flow rate.

In the above embodiments, referring to Figure 22, the outlet ends of multiple converging branch lines 407 can be integrated into the same port, which is then connected to the converging water passage 405; similarly, the outlet ends of multiple second outlet water passages 404 can be integrated into the same port, which is then connected to the converging water passage 405, thereby facilitating the mixing of ultrafiltration water and pure water in the converging water passage 405; the inlet ends of multiple second wastewater passages 406 are connected to the corresponding reverse osmosis filter element 31, and their outlet ends can also be integrated into the same port, from which wastewater is discharged uniformly.

In some embodiments, referring to Figure 22, when the outlets of multiple converging branch lines 407 are integrated into the same port, multiple parallel branch water lines 408 can be provided between this port and the converging water line 405. Each branch water line 408 is equipped with a pulse regulating valve 412. By controlling the opening and closing degree of the pulse regulating valve 412, the amount of ultrafiltration water used for mixing can be controlled. The parallel branch water lines 408 are designed to increase the flow rate of ultrafiltration water. In addition, a pressure reducing valve 430 can be provided between this port and the parallel branch water lines 408, that is, the water pressure is adjusted after the multiple ultrafiltration water lines are mixed first, which plays a role in stabilizing the water flow.

In the above embodiment, referring to Figure 22, the number of branch water passages 408 can be two. Each confluence branch 407 can be equipped with a one-way valve 429 to allow water to flow in one direction. Specifically, the one-way valve 429 can be located upstream of the pressure reducing valve 430. The pressure reducing valve 430 and the pulse regulating valve 412 can both be electrically connected to at least one of the first circuit board 141 and the second circuit board 145. At least one of the first circuit board 141 and the second circuit board 145 can control the operating state of the pressure reducing valve 430 and the pulse regulating valve 412, thereby improving the automation level of the water purification equipment 10.

In some embodiments, referring to FIG22, when the outlet ends of multiple second water outlet channels 404 are integrated into the same port, a pressure reducing valve 430 may be provided between this port and the confluence water channel 405. That is, the multiple pure waters are first mixed and then the water pressure is adjusted to stabilize the water flow. In addition, each second water outlet channel 404 may be provided with a one-way valve 429 to allow the water to flow in one direction. Specifically, the one-way valve 429 may be located between the reverse osmosis filter element 31 and the pressure reducing valve 430.

In some embodiments, referring to FIG22, the water channel structure 400 may further include an electronic component electrically connected to at least one of the first circuit board 141 and the second circuit board 145.

The first TDS detector 413 is disposed in the second outlet water channel 404 and is used to detect the TDS value of the initial ultrafiltration water in real time. The second TDS detector 414 is disposed in the confluence water channel 405 and is used to detect the TDS value of the mixed water in real time. By comparing the TDS value of the initial ultrafiltration water and the TDS value of the mixed water, the user can adjust the respective amounts of ultrafiltration water and pure water used for mixing according to the values.

In the above embodiments, the first TDS detector 413 and the second TDS detector 414 can be TDS probes, and the first TDS detector 413 can also be located in the confluence branch 407 through which ultrafiltration water flows. A pulse regulating valve 412 is provided for the branch water path 408 mentioned above. In one embodiment, the user can adjust the opening degree of the pulse regulating valve 412 according to the TDS value of the initial ultrafiltration water and the TDS value of the mixed water, so as to adjust the amount of ultrafiltration water used for mixing and thus adjust the TDS value of the mixed water.

In some embodiments, the detection component includes multiple pressure detection elements. Pressure detection elements can be provided both upstream and downstream of the filter element along the water flow direction. The pressure detection elements are used to measure water pressure in real time. By comparing the pressure difference of the water flow upstream and downstream of the same filter element, the clogging status of the filter element can be determined, thereby timely reminding the user to clean or replace the corresponding filter element.

This application does not limit the specific selection of the pressure detection element. In some embodiments, the pressure detection element can be a pressure sensor.

In some embodiments of this application, referring to FIG22, a first pressure sensor 415 may be provided upstream of the pretreatment filter element 22. The first pressure sensor 415 measures a first pressure value in real time. The value of the first pressure value allows the user to determine whether the water purification device 10 is short of water. If the value of the first pressure value is less than a certain preset value, the water purification device 10 is in a water shortage state. A second pressure sensor 416 may be provided between the pretreatment filter element 22 and the ultrafiltration filter element 21. The second pressure sensor 416 measures a second pressure value in real time. By comparing the first pressure value and the second pressure value and calculating the difference between the two, when the difference is greater than a certain preset value, the pretreatment filter element is short of water. The filter element 22 is in a blocked state. A third pressure sensor 417 can be installed between the ultrafiltration filter element 21 and the reverse osmosis filter element 31. The third pressure sensor 417 measures the third pressure value in real time. By comparing the second pressure value and the third pressure value and calculating the difference between the two, the ultrafiltration filter element 21 is in a blocked state when the difference is greater than a certain preset value. A fourth pressure sensor 418 can be installed between the reverse osmosis filter element 31 and the pressure tank 311. The fourth pressure sensor 418 measures the fourth pressure value in real time.

In some embodiments, referring to FIG22, the detection component may further include a first flow meter 420, which may be located in the confluence water passage 405 to measure the flow rate of the mixed water.

In the above embodiment, referring to FIG22, the water confluence channel 405 may also be provided with a one-way valve 429 to make the water flow in one direction. Along the flow direction of the water flow, the one-way valve 429 may be located downstream of the first flow meter 420, and the fourth pressure sensor 418 and the second TDS detector 414 may be located downstream of the one-way valve 429 in sequence.

In some embodiments, referring to FIG22, the water circuit structure 400 further includes a backwash water circuit 409 connected to the ultrafiltration filter element 21. The backwash water circuit 409 is equipped with a flushing solenoid valve 421 electrically connected to the first circuit board 141. The first circuit board 141 can control the operating state of the flushing solenoid valve 421 to achieve backwashing of the ultrafiltration filter element 21. The first circuit board 141 can adjust the flushing frequency and flushing force of the flushing solenoid valve 421 on the ultrafiltration filter element 21 according to the difference between the second pressure value and the third pressure value. When the ultrafiltration filter element 21 becomes clogged, the backwash water circuit 409 can backwash the ultrafiltration filter element 21, effectively reducing the risk of clogging and reducing impurities adhering to the surface of the ultrafiltration filter element 21, thereby improving the service life of the ultrafiltration filter element 21.

In the above embodiments, the flushing solenoid valve 421 can be a normally closed solenoid valve. For embodiments where the water circuit structure 400 includes a first wastewater circuit 403, the backwashing circuit 409 can be the first wastewater circuit 403, that is, the flushing solenoid valve 421 can be located in the first wastewater circuit 403.

In some embodiments, referring to FIG22, the water circuit structure 400 further includes a first inlet solenoid valve 422, a second inlet solenoid valve 423, and a wastewater solenoid valve 424 electrically connected to at least one of the first circuit board 141 and the second circuit board 145.

The first inlet solenoid valve 422 can be electrically connected to the first circuit board 141. When backwashing of the ultrafiltration filter element 21 is required, the first circuit board 141 can control the first inlet solenoid valve 422 to be closed. The system controls the flushing solenoid valve 421 to be in the open state to achieve backwashing of the ultrafiltration filter element 21.

In some embodiments, referring to FIG22, the water circuit structure 400 further includes a backup branch 410. The inlet end of the backup branch 410 is connected to the outlet end of the pretreatment filter element 22, and the outlet end of the backup branch 410 is connected to the inlet end of the ultrafiltration filter element 21. The backup branch 410 may be equipped with a first manual ball valve 425, so that when the first inlet solenoid valve 422 fails (is in a closed state and cannot be opened), the user can manually open the first manual ball valve 425, so that the water treated by the pretreatment filter element 22 can flow to the ultrafiltration filter element 21 for further treatment, which is beneficial to improving the reliability of the operation of the water purification equipment 10.

In some embodiments, referring to FIG22, the water circuit structure 400 further includes a second manual ball valve 426, which is located in the confluence water circuit 405. When the circuit control of the water purification device 10 is in a faulty state, there may be a situation where the pressure tank 311 is full of water but the water purification device 10 is still producing water, causing mixed water to continue flowing to the pressure tank 311. In this case, the user can operate the second manual ball valve 426 to cut off the confluence water circuit 405, thereby preventing water from overflowing from the pressure tank 311 and causing waste.

In some embodiments, referring to FIG22, the water circuit structure 400 further includes a backup water circuit 411. The inlet end of the backup water circuit 411 is connected to the outlet end of the pretreatment filter element 22, and the outlet end of the backup water circuit 411 can directly draw water out. The backup water circuit 411 may be equipped with a third solenoid valve 428, a one-way valve 429, and a third manual ball valve 427. The third solenoid valve 428 can be a normally closed solenoid valve. When the circuit control of the water purification device 10 is in a normal state, the backup water circuit 411 is in a cut-off state. When the circuit control of the water purification device 10 is in a fault state, the user can open the third solenoid valve 428, and the water filtered by the pretreatment filter element 22 can be drawn out as backup water for purposes such as cleaning.

In the above embodiment, the third manual ball valve 427 can be a three-way manual ball valve. The first and second ends of the three-way manual ball valve can be used to connect to the backup water circuit 411, and its third end can be connected to the outlet end of the ultrafiltration filter element 21. When the circuit control of the water purification device 10 is in a normal state, it can be understood that at least one of the first circuit board 141 and the second circuit board 145 can control the normal operation of the relevant electronic components, and the water purification device 10 can filter the raw water according to the control of at least one of the first circuit board 141 and the second circuit board 145. Conversely, when the circuit control of the water purification device 10 is in a fault state, it can be understood that at least one of the first circuit board 141 and the second circuit board 145 cannot control the normal operation of the relevant electronic components, causing the water purification device 10 to be unable to filter the raw water. At this time, the water circuit structure 400 can ensure the user's normal water use by adding the equipment water circuit 411.

It is worth noting that in some embodiments of this application, the solenoid valve and the one-way valve 429 mentioned above can both be electrically connected to at least one of the first circuit board 141 and the second circuit board 145. At least one of the first circuit board 141 and the second circuit board 145 can control the operating status of multiple valves respectively, thereby improving the automation level of the water purification equipment 10.
