Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways than the embodiments described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0054] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying order, relative importance, or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integrally formed connection; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through intermediate elements; they can refer to the internal communication of two elements or the interaction between two elements, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0056] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0057] It should be noted that if a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or it can be an intermediate component. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation. "Inner" and "outer" refer to the inner and outer contours of the corresponding components. "Upstream" and "downstream" are defined in relation to the flow direction of water in the water purification equipment, while "upper" and "lower" are defined in relation to the height direction of the water purification equipment.

[0058] 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.

[0059] In some embodiments, referring to Figures 1 to 3, 14, 15 and 22, the water purification device 10 includes a filtration module for water treatment. 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 (the water that has just entered the water purification device 10) to obtain ultrafiltration water. After being treated by the ultrafiltration filter element 21, most of the silt, rust, suspended solids and colloids in the raw water can be filtered out, thereby ensuring the safety of the water quality.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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, which is usually below 0.0001 microns, and can filter out 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 include an ultrafiltration module 20, a reverse osmosis module 30, and a water storage module 310 at the same time to achieve multiple treatments of the raw water, which is beneficial to achieving drinking water safety.

[0068] 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.

[0069] In some embodiments, the ultrafiltration module 20, reverse osmosis module 30, and water storage module 310 of the water purification device 10 can have at least three arrangement methods. The first arrangement method is that 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 method is that the ultrafiltration module 20 and 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 method is that the ultrafiltration module 20, reverse osmosis module 30, and water storage module 310 are each three independent devices.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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. The mounting plates 122 can provide installation positions for the valves, pipes, or valves and pipes, and can support the valves, pipes, or valves and pipes.

[0080] In some embodiments, the filter element of the ultrafiltration module 20 can be detachably connected to the load-bearing plate 1, that is, both the pretreatment filter element 22 and the ultrafiltration filter element 21 can be detachably connected to the load-bearing plate 1, thereby facilitating the maintenance or replacement of the pretreatment filter element 22 and the ultrafiltration filter element 21. Referring to Figures 1 to 3, since the pretreatment filter element 22 and the ultrafiltration filter element 21 are arranged in parallel and detachably connected to the same side of the load-bearing plate 1, along the extending direction of the pretreatment filter element 22 and the ultrafiltration filter element 21, the end of the pretreatment filter element 22 and the ultrafiltration filter element 21 away from the load-bearing plate 1 can have a first gap 120 between it and the first housing 100, thereby facilitating the assembly and disassembly of the pretreatment filter element 22 and the ultrafiltration filter element 21.

[0081] This application does not limit the specific method of the aforementioned detachable connection. In some embodiments, the detachable method can be a fastener, that is, the relevant components can all be provided with a first connection hole, and the fastener can pass through the first connection hole to realize the connection of the relevant components. The fastener includes, but is not limited to, bolts and nuts. In other embodiments, the detachable method can also be a snap-fit ​​connection.

[0082] In some embodiments, referring to Figures 1 to 3 and Figure 14, the bottom of the first housing 100 may be provided with a first roller 121 for rolling contact with the ground, so that the first housing 100 can move relative to the ground, facilitating the user to transfer the device integrating the ultrafiltration module 20 and the reverse osmosis module 30.

[0083] This application does not specifically limit the number of first rollers 121. In some embodiments, referring to Figures 1 to 3 and Figure 14, the number of first rollers 121 can be four, and the four first rollers 121 can be respectively set near the four apex corners of the bottom of the first housing 100.

[0084] This application does not specifically limit the shape of the first housing 100. In some embodiments, the shape of the first housing 100 can be cylindrical, such as cylindrical, cubic, cuboid, etc.

[0085] In some embodiments, referring to Figures 1, 3, and 5, the reverse osmosis filter element 31 and the drive element 32 of the reverse osmosis module 30 can be detachably connected to at least one of the load-bearing plate 1 and the hanging plate 2, respectively. In some examples of this application, the reverse osmosis filter element 31 is detachably connected to the hanging plate 2, and the drive element 32 is detachably connected to the load-bearing plate 1. The reverse osmosis filter element 31 can be located in the second region 5, and the drive element 32 can be located in the third region 6. Since the water circuit structure 400 includes multiple valves and pipes, in order to facilitate the replacement and maintenance of the reverse osmosis filter element 31, most of the valves and pipes of the water circuit structure 400 can be concentrated in the third region 6. This can, to a certain extent, avoid the obstruction of the reverse osmosis filter element 31 by the valves and pipes, and help improve the internal orderliness of the water purification equipment 10.

[0086] Specifically, in some embodiments, referring to Figures 1, 3, and 5 to 8, the reverse osmosis module 30 may include a first mounting assembly 220 disposed on the mounting plate 2. The first mounting assembly 220 is used to mount the reverse osmosis filter element 31. The first mounting assembly 220 may include a filter element holder 221 detachably connected to the mounting plate 2. The filter element holder 221 may include a fixing part 222 and a mounting part 226 connected to each other. The fixing part 222 is detachably connected to the mounting plate 2, and the mounting part 226 is used to detachably connect to the reverse osmosis filter element 31.

[0087] In the above embodiments, referring to FIG8, the fixing part 222 and the mounting part 226 can be detachably connected. For example, the fixing part 222 and the mounting part 226 can be rotatably engaged.

[0088] In some embodiments, referring to FIG8, the fixing part 222 may include two symmetrically arranged supports 223, which can jointly clamp the mounting part 226 from the top and bottom. The mounting plate 2 may be provided with a plurality of spaced first through holes 225, and the supports 223 can be selectively connected to a portion of the plurality of first through holes 225. Fasteners can be inserted through the first through holes 225 to realize a detachable connection between the supports 223 and the mounting plate 2. The arrangement of the plurality of first through holes 225 facilitates the adjustment of the position of the supports 223 on the mounting plate 2, thereby facilitating the connection between the mounting part 226 and the reverse osmosis filter element 31.

[0089] This application does not specifically limit the detachable method of the mounting part 226 and the reverse osmosis filter element 31. In some embodiments, referring to Figures 6 and 7, the mounting part 226 and the reverse osmosis filter element 31 can be connected by a snap-fit ​​connection. Specifically, a groove 7 can be formed at the end of the mounting part 226 facing the reverse osmosis filter element 31, and a locking block 8 that engages with the groove 7 can be formed at the end of the reverse osmosis filter element 31. In actual operation, the reverse osmosis filter element 31 can be first connected to the mounting part 226, and then the reverse osmosis filter element 31 can be rotated to make the locking block 8 on the reverse osmosis filter element 31 rotate and engage with the groove 7. In other embodiments, a locking block 8 can also be formed on the mounting part 226, and a groove 7 that engages with the locking block 8 can be formed at the end of the reverse osmosis filter element 31. This application does not limit the rotation angle of the reverse osmosis filter element 31. In some embodiments, the rotation angle can be 90° or 180°.

[0090] In some embodiments, referring to Figures 6 to 8, the mounting part 226 may include a housing 227 and a connector core 228 disposed within the housing 227. The housing 227 forms a slot 7, and the connector core 228 forms an inlet channel, an outlet channel, and a wastewater channel for connection with the reverse osmosis filter element 31. The end of the inlet channel away from the reverse osmosis filter element 31 is used to connect to the outlet end of the ultrafiltration filter element 21, the end of the outlet channel away from the reverse osmosis filter element 31 is used to connect to the pressure tank 311, and the end of the wastewater channel away from the reverse osmosis filter element 31 is used to connect to the wastewater channel in the water channel structure 400.

[0091] In some embodiments, referring to Figures 1, 3, and 5, the first mounting assembly 220 may further include a clamping member 232 detachably connected to the mounting plate 2, the clamping member 232 being used to clamp the reverse osmosis filter element 31. The overall structure of the clamping member 232 may be C-shaped to adapt to the shape of the reverse osmosis filter element 31. Through the arrangement of the filter element holder 221 and the multiple clamping members 232, the reverse osmosis filter element 31 can be hung on the mounting plate 2.

[0092] In the above embodiments, referring to Figures 1, 3, and 5, the number of clamping members 232 can be multiple, and the multiple clamping members 232 can be spaced apart along the extension direction of the reverse osmosis filter element 31, thereby improving the support effect on the reverse osmosis filter element 31. The extension direction of the reverse osmosis filter element 31 can be the second direction X, that is, the length direction of the water purification device 10, and the pretreatment filter element 22 and the ultrafiltration filter element 21 of the ultrafiltration module 20 can be arranged spaced apart along the second direction X.

[0093] In some embodiments, referring to Figures 1, 3 and 5, the first mounting assembly 220 may further include a reinforcing member 233 detachably connected to the mounting plate 2. The overall structure of the reinforcing member 233 may be U-shaped, and the opening orientation of the reinforcing member 233 is the same as the opening orientation of the clamping member 232. The two ends of the reinforcing member 233 may be connected to the two ends of the clamping member 232 respectively. The setting of the reinforcing member 233 can improve the strength of the clamping member 232, which is beneficial to improving the support effect on the reverse osmosis filter element 31 and can prevent the clamping member 232 from breaking to a certain extent.

[0094] This application does not specifically limit the number of first mounting components 220. The number of first mounting components 220 can be the same as the number of reverse osmosis filter elements 31, and one first mounting component 220 can be used to install one reverse osmosis filter element 31. In the embodiments of this application, referring to Figures 1, 3 and 5, the number of first mounting components 220 can be two, corresponding to two reverse osmosis filter elements 31, and the two first mounting components 220 can be spaced apart along the first direction Z.

[0095] In some embodiments, the mounting plate 2 and the load-bearing plate 1 may each be provided with a plurality of pipe holes 123 for pipes to pass through. This application does not specifically limit the number of pipe holes 123, and their number can be modified according to the specific pipe layout. In some examples of this application, the number of pipe holes 123 on the mounting plate 2 may be the same as the number of reverse osmosis filter elements 31, and the pipe holes 123 and reverse osmosis filter elements 31 are arranged in a one-to-one correspondence. The pipe connected to the outlet end of the ultrafiltration filter element 21 can pass through the pipe holes 123 on the load-bearing plate 1 and the mounting plate 2, and connect to the inlet channel of the connector inner core 228, thereby enabling ultrafiltration water to be transported to the reverse osmosis filter element 31 for reverse osmosis treatment.

[0096] In the above embodiments, referring to Figures 1, 3 and 5, the two supports 223 of the same first mounting component 220 can be symmetrically arranged about the pipe hole 123 on the mounting plate 2, so that the distance between the pipe hole 123 on the mounting plate 2 and the water inlet channel of the connector core 228 can be smaller, thereby facilitating the connection between the pipe passing through the pipe hole 123 and the water inlet channel, reducing unnecessary pipe length, lowering the connection cost of the water purification equipment 10, and improving the aesthetics of the interior of the water purification equipment 10.

[0097] In some embodiments, referring to FIG8, the support 223 of the fixing part 222 may be formed with an installation groove 224. The installation groove 224 can provide an installation position for the pipe passing through the pipe hole 123 of the hanging plate 2, thereby avoiding the pipe from getting tangled or knotted to a certain extent, which is beneficial to improving the internal regularity of the water purification equipment 10.

[0098] In some embodiments, the pretreatment filter element 22 and the ultrafiltration filter element 21 may be provided with pressure relief valves respectively, and the load-bearing plate 1 may be provided with a second through hole for the pressure relief valve to pass through. When the operator disassembles the pretreatment filter element 22 and the ultrafiltration filter element 21, he / she can first operate the pressure relief valve to release pressure, thereby facilitating the disassembly of the pretreatment filter element 22 and the ultrafiltration filter element 21.

[0099] In some embodiments, referring to Figures 2, 9, and 10, the reverse osmosis module 30 may further include a second mounting assembly 240 for mounting the drive component 32. The second mounting assembly 240 may be disposed on at least one of the mounting plate 2 and the load-bearing plate 1. In some embodiments of this application, the second mounting assembly 240 is disposed on the load-bearing plate 1. The second mounting assembly 240 may include a first mounting bracket 241 and a shock absorber 242. The first mounting bracket 241 is detachably connected to the load-bearing plate 1 and is used to mount the drive component 32. The shock absorber 242 is disposed between the first mounting bracket 241 and the load-bearing plate 1 to provide shock absorption and buffering. The detachable connection between the first mounting bracket 241 and the load-bearing plate 1 allows the drive component 32 to be mounted on the first mounting bracket 241 before the entire assembly is connected to the load-bearing plate 1. This facilitates operation and improves the assembly efficiency of the water purification equipment 10.

[0100] In the above embodiments, referring to Figures 2, 9, and 10, a shock absorber 242 may also be provided on the side of the first mounting bracket 241 facing away from the load-bearing plate 1. This application does not limit the specific selection of the shock absorber 242. In some embodiments, the shock absorber 242 may be made of a shock-absorbing material, such as rubber or silicone, and may be a rubber pad. This application also does not specifically limit the detachable connection method between the first mounting bracket 241 and the load-bearing plate 1. In some embodiments, the first mounting bracket 241 and the load-bearing plate 1 may be connected using fasteners. The shock absorber 242, the first mounting bracket 241, and the load-bearing plate 1 may all have second connecting holes, through which the fasteners can pass.

[0101] It should be noted that Figure 9 shows the reverse osmosis module 30 including two second mounting components 240. When understanding the detachable connection between the first mounting bracket 241 and the load-bearing plate 1, and the detachable connection method between the first mounting bracket 241 and the load-bearing plate 1, such as the connection by fasteners, you can refer to the lower second mounting component 240 and the load-bearing plate 1 shown in Figure 2 and Figure 9.

[0102] This application does not specifically limit the number of second mounting components 240. In some embodiments, the number of second mounting components 240 can be the same as the number of driving members 32, and they are arranged in a one-to-one correspondence with driving members 32. That is, there can be two second mounting components 240, and the two second mounting components 240 can be arranged at a distance along the first direction Z. Specifically, as shown in FIG9, two second mounting components 240 are arranged for two driving members 32, and the two driving members 32 are arranged at a distance along the first direction Z. The second mounting component 240 corresponding to the lower driving member 32 is arranged on the load-bearing plate 1; the second mounting component 240 corresponding to the upper driving member 32 is arranged between the two driving members 32.

[0103] In some embodiments, the reverse osmosis module 30 may further include a support member 243 connected to the load-bearing plate 1. The support member 243 is formed in a U-shape, with its open end connected to the load-bearing plate 1. At least one drive member 32 can pass through the cavity formed by the support member 243. The support member 243 has a support end opposite to the open end, which provides an installation position for the drive member 32. Optionally, referring to Figures 2 and 9, the lower drive member 32 passes through the cavity formed by the support member 243.

[0104] In the above embodiments, referring to Figures 2 and 9, the support member 243 can be a U-shaped support plate, the open end of the support plate can be detachably connected to the load-bearing plate 1, and the support end of the support plate can be detachably connected to the first mounting bracket 241 corresponding to the upper drive member 32.

[0105] In some embodiments, referring to FIG9, the reverse osmosis module 30 may further include a fixing plate 244 disposed between the support member 243 and the load-bearing plate 1. The fixing plate 244 may be detachably connected to both the support member 243 and the load-bearing plate 1, thereby facilitating maintenance or replacement of the drive member 32. When installing the drive member 32, the fixing plate 244, the drive member 32, the support member 243, the first mounting bracket 241, and the shock absorber 242 may be assembled first, and then the assembled whole may be connected to the load-bearing plate 1, thereby improving the assembly efficiency of the water purification equipment 10.

[0106] In some embodiments, referring to Figures 1 to 4, the first housing 100 of the water purification device 10 may include a base plate 114 and a base 113 connected to each other. The base 113 and the first roller 121 are respectively disposed on both sides of the base plate 114. The base 113 is provided with a first through hole 125, a second through hole 126 and a third through hole 127. The first through hole 125 is used for the water inlet connector to pass through, the second through hole 126 is used for the water outlet connector to pass through, and the third through hole 127 is used for the wastewater connector to pass through. The base 113 can provide installation positions for the water inlet connector, the water outlet connector and the wastewater connector at the same time.

[0107] In some embodiments, referring to Figures 2 and 4, the base 113 is recessed into the interior of the water purification device 10 to form a receiving cavity 128. The receiving cavity 128 is connected to the first through hole 125, the second through hole 126 and the third through hole 127. The receiving cavity 128 can accommodate the water inlet connector, the water outlet connector and the wastewater connector to a certain extent, thereby preventing the water inlet connector, the water outlet connector and the wastewater connector from being exposed. It also prevents the water inlet connector, the water outlet connector and the wastewater connector from colliding with the outside world to a certain extent, which is beneficial to protecting the water inlet connector, the water outlet connector and the wastewater connector.

[0108] In some embodiments, referring to Figures 1, 2 and 14, the first housing 100 of the water purification device 10 may further include a top plate 115 and two side plates 116. The top plate 115 is disposed opposite to the bottom plate 114. Both side plates 116 extend along the first direction Z. The two side plates 116 are spaced apart in the second direction X and located between the top plate 115 and the bottom plate 114. The two ends of the two side plates 116 in the first direction Z are respectively connected to the top plate 115 and the bottom plate 114. The base 113 extends along the second direction X and is connected to the two side plates 116.

[0109] In some embodiments, referring to Figures 1 to 3 and Figure 14, the first housing 100 of the water purification device 10 may further include a front door 117 and a rear door 118 spaced apart in the third direction Y. Each side of the front door 117 and the rear door 118 is rotatably connected to a side plate 116. Both the front door 117 and the rear door 118 are in a closed state. When the front door 117 is in the closed state, both ends of the front door 117 in the first direction Z abut against the top plate 115 and the bottom plate 114, respectively. When the rear door 118 is in the closed state, both ends of the rear door 118 in the first direction Z abut against the top plate 115 and the base 113, respectively.

[0110] In the above embodiment, the front door 117 and the rear door 118 each have an open state. The open state means that the front door 117 and the rear door 118 rotate relative to the side plate 116 to move away from the load-bearing plate 1, thereby facilitating the user to replace or maintain the filter element inside the first housing 100. Multiple valves and pipes in the water circuit structure 400 can be positioned as close as possible to the rear door 118, so that the internal structure of the water purification equipment 10 appears more aesthetically pleasing when the front door 117 is open, and also facilitates the user to replace the filter element located on the front side.

[0111] This application does not limit the specific shapes of the bottom plate 114, side plate 116, top plate 115, front door 117 and rear door 118. Their shapes can be modified according to the needs of actual application scenarios. In some embodiments, the bottom plate 114, side plate 116, top plate 115, front door 117 and rear door 118 can all be formed as planar plates, so that the first housing 100 as a whole can be formed as a prism, such as a cuboid or a cube.

[0112] In some embodiments, referring to FIG3, the first housing 100 may further include a plurality of reinforcing ribs 119. The plurality of reinforcing ribs 119 may extend along at least one of the second direction X and the third direction Y. The reinforcing ribs 119 may be connected to the side plate 116, the load-bearing plate 1, etc., thereby improving the structural strength of the first housing 100 and to a certain extent preventing the first housing 100 from being dented after a collision.

[0113] In some embodiments, the water purification device 10 further includes a locking structure for locking the front door 117 when it is closed, and locking the rear door 118 when it is closed. This application does not limit the specific principle by which the locking structure achieves locking. For example, the locking structure can employ magnetic attraction, snap-fit, or other principles to achieve locking, and its specific structure may include, but is not limited to, magnets, slots, and blocks.

[0114] In some embodiments, referring to Figures 1 to 3 and Figure 11, the water purification device 10 may include a panel structure 130. The panel structure 130 may include a panel frame 131 and an electrical component 140 disposed on the panel frame 131.

The first receiving area 135 is used to receive the electrical component 140, and the second receiving area 137 is used to receive pipes. Since fluid (water) flows inside the pipes, by reasonably dividing the internal space of the panel frame 131, the electrical component 140 can be located in the first receiving area 135 of the panel frame 131, and the pipes of the water purification device 10 can be located in the second receiving area 137 of the panel frame 131, which can improve the regularity and aesthetics of the panel structure 130. The first receiving area 135 and the second receiving area 137 are not interconnected, which can, to a certain extent, prevent water from leaking from the pipes and coming into contact with the electrical component 140, thereby protecting the electrical component 140 and reducing the safety hazards during the operation of the water purification device 10.

[0115] In the above embodiment, the panel frame 131 has a first partition disposed between the first receiving area 135 and the second receiving area 137, so that the first receiving area 135 and the second receiving area 137 are not connected to each other. The bottom of the panel frame 131 can be connected to the end of the hanging plate 2 away from the load-bearing plate 1, and the top of the panel frame 131 can be connected to the top plate 115 of the first housing 100.

The partition plate 133 may be a second partition plate 3, which is used to support the top plate 115, thereby further preventing the top plate 115 from denting under stress. The panel frame 131 includes two sub-regions 136 of the first accommodating area 135 and a second accommodating area 137. Each region can be used to accommodate different components. By rationally dividing the internal space of the panel frame 131, the regularity and aesthetics of the panel structure 130 can be improved.

[0119] In some embodiments, referring to FIG11, the power supply 146 can be electrically connected to the first circuit board 141 and the drive unit 32 by means of a cable. The panel frame 131 can be formed with a through hole 132 communicating with the third region 6. One end of the cable can be connected to the drive unit 32, and the other end passes through the through hole 132 to connect with the power supply 146.

One end of the cable can be connected to the power supply 146, and the other end passes through the through groove 134 to connect with the first circuit board 141.

[0120] In some embodiments, the second receiving area 137 may communicate with the third area 6 so that the pipe in the third area 6 can be arranged in the second receiving area 137. Furthermore, the pipe in the second receiving area 137 is provided with a bypass valve, and the panel frame 131 is provided with a switch 138 for adjusting the opening degree of the bypass valve. The user can turn the switch 138 to open or close the pipe.

[0121] In the above embodiments, the panel frame 131 may be provided with a switch hole for mounting a switch 138. The switch 138 may be located on the outside of the panel frame 131 for easy screwing by the user. This application does not limit the specific selection of the bypass valve; in some embodiments, the bypass valve may be a ball valve.

[0122] In some embodiments, referring to FIG12, the panel structure 130 may further include a second mounting bracket 144 for mounting the first circuit board 141, the second mounting bracket 144 being detachably connected to the first housing 100 of the water purification device 10.

[0123] In some embodiments, referring to Figures 11 and 12, the panel structure 130 may further include a display screen 142 disposed on the panel frame 131. The display screen 142 is electrically connected to the first circuit board 141 and is used to display relevant data and information about the operation of the water purification device 10.

Those skilled in the art can design button holes of different shapes and sizes according to actual conditions; for example, they can be square, circular, etc. This application does not specifically limit the number of button holes; those skilled in the art can design them according to actual conditions. For example, two, three, or four button holes can be provided. In one embodiment of this application, the button holes can be circular, and the number of button holes and mechanical buttons 143 can both be four.

[0127] In the above embodiment, referring to FIG14, the front door 117 may be provided with a display window 147, which may be formed as a transparent plate. The transparent plate may be embedded in the screen hole 148, thereby facilitating the user to observe the data of the display screen 142 and helping to protect the display screen 142.

[0128] Referring to Figure 15, taking the third arrangement as an example, the ultrafiltration module 20, reverse osmosis module 30, and water storage module 310 are each three independent devices. This allows users to combine them in different ways according to their actual needs, offering high assembly flexibility. For example, users can choose only one of the ultrafiltration module 20, the reverse osmosis module 30, and the water storage module 310, or any two of the three devices, or all three simultaneously. When the user's actual needs change, it is also easy to modify the original device combination, such as by adding or removing hoses. The outlet of the ultrafiltration module 20 is detachably connected to the inlet of the reverse osmosis module 30, and the inlet of the water storage module 310 is detachably connected to the outlets of both the ultrafiltration module 20 and the reverse osmosis module 30.

The first housing 100 and the second housing 200 may be detachably connected, and the water outlet of the ultrafiltration module 20 may be detachably connected to the water inlet of the reverse osmosis module 30.

[0130] In some embodiments, referring to Figures 17 to 20, the reverse osmosis filter element 31 and the drive element 32 of the reverse osmosis module 30 can both extend along the first direction Z. The drive element 32 is detachably connected to the inner wall of the second housing 200. The top of the second housing 200 can be provided with a fixing seat 210, and a filter element holder 221 is detachably connected to the fixing seat 210. The reverse osmosis filter element 31 is detachably connected to the filter element holder 221. The structure of the filter element holder 221 here is similar to the structure of the filter element holder in the second arrangement described above, so it will not be described in detail here.

[0131] In the above embodiments, referring to Figures 17 and 18, along the extending direction of the reverse osmosis filter element 31, a second gap 234 may exist between the end of the reverse osmosis filter element 31 away from the fixing base 210 and the second housing 200, thereby facilitating the assembly and disassembly of the reverse osmosis filter element 31. The bottom of the second housing 200 may be provided with a second roller 250 for rolling contact with the ground, so that the second housing 200 can move relative to the ground, facilitating the user to transfer the reverse osmosis module 30.

[0132] This application does not specifically limit the number of the second rollers 250. In some embodiments, referring to Figures 15 to 18, the number of the second rollers 250 can be four, and the four second rollers 250 can be respectively arranged near the four apex corners of the bottom of the second housing 200.

[0133] In some embodiments, referring to FIG19, the mounting base 210 is formed with a mounting cavity 211 for mounting the power supply 146. The mounting cavity 211 is also provided with a second circuit board 145 electrically connected to the power supply 146. The second circuit board 145 is electrically connected to a plurality of valves and actuators 32 of the water circuit structure 400. The second circuit board 145 can control the operating status of the plurality of valves and actuators 32 of the reverse osmosis module 30. For example, the second circuit board 145 can control the working efficiency of the actuators 32.

[0134] In some embodiments, the second circuit board 145 can be electrically connected to the first circuit board 141 to achieve overall information integration of the water purification device 10, making it easier for users to obtain more comprehensive information and data about the water purification device 10 on the display screen 142. This application does not limit the specific method of electrically connecting the second circuit board 145 and the first circuit board 141. In some embodiments, the second circuit board 145 can be electrically connected to the first circuit board 141 via cables, Bluetooth, or WIFI. At least one of the first circuit board 141 and the second circuit board 145 is the main control module 9 of the water purification device 10.

[0135] In some embodiments, the second housing 200 is provided with a second mounting assembly 240 for mounting the drive component 32, the structure of which is similar to that of the first mounting assembly 220 described above, and therefore will not be described in detail here.

[0136] In some embodiments, the second housing 200 is provided with a fourth through hole, and the water outlet end of the ultrafiltration filter element 21 in the first housing 100 can be connected to the water inlet end of the reverse osmosis filter element 31 in the second housing 200 by means of a hose, and the fourth through hole is used for the hose to pass through.

[0137] In some embodiments, referring to Figures 15 and 21, the water purification device 10 may further include a third housing 300 with a water storage module 310. At least one of the outlet end of the ultrafiltration filter element 21 in the first housing 100 and the outlet end of the reverse osmosis filter element 31 in the second housing 200 may be connected to the inlet end of the water storage module 310 of the third housing 300 via a hose. When the water purification device 10 includes only the first housing 100 and the third housing 300, the outlet end of the ultrafiltration module 20 in the first housing 100 may be connected to the inlet end of the water storage module 310 in the third housing 300.

[0138] In some embodiments, any two of the first housing 100, the second housing 200 and the third housing 300 are detachably connected, thereby facilitating the combination and matching of the water purification equipment 10, and allowing users to combine and match the water purification functions of the water purifier according to their actual needs.

[0139] In the above embodiments, the outlet of the ultrafiltration module 20 is detachably connected to the inlet of the reverse osmosis module 30, and the inlet of the water storage module 310 is detachably connected to the outlets of both the ultrafiltration module 20 and the reverse osmosis module 30, so as to connect any two of the first housing 100, the second housing 200, and the third housing 300. Alternatively, any two of the first housing 100, the second housing 200, and the third housing 300 can be directly connected, for example, by means of bolts, nuts, snap-fits, etc.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] In some embodiments, referring to FIG22, the number of driving components 32 and reverse osmosis filter elements 31 can be multiple. 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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 electronic component may include a detection component for detecting the TDS (Total Dissolved Solids) value, pressure value, flow rate value, etc. of the water flow. At least one of the first circuit board 141 and the second circuit board 145 is able to acquire the detection information of the detection component and display the detection information on the display screen 142.

[0156] In some embodiments, the electronic components may also include a plurality of solenoid valves disposed in the water passage structure 400. The plurality of solenoid valves may 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 may control the operating state of the corresponding solenoid valve. The operating state includes, but is not limited to, opening and closing the solenoid valve.

[0157] In some embodiments, referring to FIG22, the detection component includes a first TDS detector 413 and a second TDS detector 414. 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.

[0158] In the above embodiments, the first TDS detector 413 and the second TDS detector 414 can be TDS probes. The first TDS detector 413 can also be located in the confluence branch 407 through which ultrafiltration water flows. In the embodiment where the branch water path 408 mentioned above is equipped with a pulse regulating valve 412, 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, thereby adjusting the amount of ultrafiltration water used for mixing and thus regulating the TDS value of the mixed water.

[0159] 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.

[0160] 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.

[0161] 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. By comparing the third pressure value and the fourth pressure value and calculating the difference between the two, the reverse osmosis filter element 31 is in a blocked state when the difference is greater than a certain preset value.

[0162] 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.

[0163] In some embodiments, referring to FIG22, the water storage module 310 may further include a water pump 419 connected to the pressure tank 311. The water pump 419 can provide energy for the user to pump water out of the pressure tank 311. The pressure tank 311 may be provided with a plurality of water level probes, which are spaced apart along the height direction of the pressure tank 311. The water level probes and the water pump 419 may 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 water pump 419 according to the water level detected by the water level probe, for example, by reducing or increasing the operating power of the water pump 419.

[0164] In some embodiments, the water storage module 310 may further include a second flow meter (not shown) located downstream of the water pump 419. The second flow meter may be electrically connected to at least one of the first circuit board 141 and the second circuit board 145. The second flow meter is used to detect whether the water flow decreases when the operating power of the water pump 419 is reduced, and to detect whether the water flow increases when the operating power of the water pump 419 is increased.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] 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 is disposed between the pretreatment filter element 22 and the ultrafiltration filter element 21, the second inlet solenoid valve 423 is disposed downstream of the ultrafiltration filter element 21, and the wastewater solenoid valve 424 is disposed in the second wastewater circuit 406 and is used to control the on / off state of the second wastewater circuit 406.

[0169] In the above embodiments, the first inlet solenoid valve 422 and the second inlet solenoid valve 423 can be normally open solenoid valves, allowing water to flow in the inlet water path 401, the first outlet water path 402, and the second outlet water path 404. A one-way valve 429 can also be provided between the first inlet solenoid valve 422 and the ultrafiltration filter element 21, which is used to ensure unidirectional water flow. 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 in a closed state and control the backwashing solenoid valve 421 to be in an open state to achieve backwashing of the ultrafiltration filter element 21.

[0170] 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.

[0171] 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.

[0172] 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.

[0173] 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.

[0174] 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.

[0175] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
