Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0022] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0023] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1This is a schematic diagram of the structure of a filter element assembly 11 provided in an embodiment of the present invention. Figure 2 This is a structural schematic diagram of a water channel board assembly provided in an embodiment of the present invention. Figure 3 yes Figure 1 The diagram shows another view of the filter assembly 11. Figure 4 yes Figure 3 The diagram shows a cross-sectional structure of the filter element assembly 11 along the A1-A2 position. Figure 5 This is a cross-sectional structural diagram of a water purification device provided in an embodiment of the present invention. The water purification device may include a filter element assembly 11 and a water circuit board assembly 12. The filter element assembly 11 is used to intercept, adsorb, or convert impurities in the water to ensure that the output water meets standards. For example, impurities may include particulate matter, heavy metals, bacteria, etc. The water circuit board assembly 12 has multiple flow channels to achieve directional distribution of water flow and physical connection of various functional modules (such as the filter element assembly 11, valves, and sensors).

[0025] The filter element assembly 11 may include a filter element body 111 and a first water channel connector 114. The first water channel connector 114 is connected to the filter element body 111, and the end of the first water channel connector 114 has a plug-in port k1. The extension direction of the plug-in port k1 is perpendicular to the axial direction of the filter element body 111. By setting the extension direction of the plug-in port k1 in this way, the overall height of the filter element assembly 11 can be reduced.

[0026] The filter element assembly 11 may include a plurality of first water inlet connectors 114 arranged side by side. Each first water inlet connector 114 can communicate with the filter element body 111. For example, the plurality of first water inlet connectors 114 may include a first water inlet connector, a first water outlet connector, and a first wastewater connector. The filter element body 111 can be used to filter the raw water flowing in from the first water inlet connector, and then the purified water flows out from the first water outlet connector for user use. Wastewater generated during the filtration process can be discharged through the first wastewater connector.

[0027] The insertion port k1 can be located at the opening of the first water connector 114. The shape of the insertion port k1 can be tubular, wherein the extension direction of the insertion port k1 refers to the axial direction of the insertion port k1.

[0028] The water circuit board assembly 12 may include a second water circuit connector 121 and a seal 122. The second water circuit connector 121 is detachably inserted into the insertion port k1 of the first water circuit connector 114. The seal 122 is sleeved on the second water circuit connector 121 and located between the outer wall of the second water circuit connector 121 and the inner wall of the insertion port k1. The water circuit board assembly 12 may include a plurality of second water circuit connectors 121 arranged side by side. The plurality of second water circuit connectors 121 and the plurality of first water circuit connectors 114 may correspond one-to-one. For example, the plurality of second water circuit connectors 121 may include a second water inlet connector, a second water outlet connector, and a second wastewater connector. The second water inlet connector, the second water outlet connector, and the second wastewater connector are respectively used to communicate with the first water inlet connector, the first water outlet connector, and the first wastewater connector.

[0029] The water circuit board assembly 12 can be movably installed in the housing of the water purification equipment, so that the second water circuit connector 121 in the water circuit board assembly 12 can be inserted into the insertion port k1 of the first water circuit connector 114, thereby connecting the filter element assembly 11 and the water circuit board assembly 12, and limiting the filter element assembly 11 through the insertion connection; or the second water circuit connector 121 can be pulled out from the insertion port k1 of the first water circuit connector 114, so that the filter element assembly 11 and the water circuit board assembly 12 can be separated. It is understood that the water purification device may also include a water circuit transition structure (not shown in the figure), which can be connected to the second water circuit connector 121 and the booster pump in the water purification equipment, so that the fluid passing through the second water circuit connector 121 can flow normally, thereby ensuring the normal operation of the filter element assembly 11.

[0030] For example, when the second water connector 121 is inserted into the first water connector 114, the raw water can enter the filter body 111 in sequence through the second water inlet connector and the first water inlet connector. The purified water can flow out through the first water outlet connector and the second water outlet connector for user use. The wastewater generated during the filtration process can be discharged through the first wastewater connector and the second wastewater connector in sequence.

[0031] For example, the seal 122 can be a sealing ring, and the material of the sealing ring can include rubber. The outer wall of the second water connector 121 can have an annular groove c1, and the extending direction of the annular groove c1 can be perpendicular to the axial direction of the second water connector 121. The seal 122 can be embedded in the annular groove c1.

[0032] Since the filter element assembly 11 is a consumable component, in this embodiment of the invention, by integrating the seal 122 onto the second water connector 121, the insertion port k1 of the first water connector 114 can adopt a simple straight-through structure. This eliminates the need for additional machining of the seal 122 groove on the inner wall of the insertion port k1, reducing machining steps and manufacturing costs for the first water connector 114. It also avoids the problem of scale buildup and bacterial growth in the seal 122 groove located on the inner wall of the insertion port k1. Furthermore, this allows the replacement cycle of the filter element assembly 11 and the seal 122 to be independent of each other. For applications requiring frequent filter element replacement or maintenance, frequent replacement of the seal 122 is unnecessary.

[0033] Furthermore, compared to the method of installing the seal 122 in the groove on the inner wall of the insertion port k1, in this embodiment of the invention, the seal 122 is fitted into the annular groove c1 on the outer wall of the second water connector 121, which can reduce the difficulty of installing and disassembling the seal 122. Furthermore, during the insertion of the second water connector 121 into the insertion port k1, the seal 122 generates a uniform radial compressive force, and the elastic deformation of the seal 122 can compensate for the difference in fit clearance caused by machining tolerances. Even if there are slight dimensional deviations in the inner wall of the insertion port k1, the seal 122 can still maintain stable sealing performance, effectively reducing the risk of leakage. Moreover, because the seal 122 is installed on the second water connector 121, the second water connector 121 of the same specification can be adapted to insertion ports k1 of different depths, improving the versatility and adaptability of components.

[0034] In summary, this utility model provides a water purification device including a filter element assembly 11 and a water circuit board assembly 12. The filter element assembly 11 includes a filter element body 111 and a first water circuit connector 114, which communicates with the filter element body 111 and has a plug-in port k1 at its end. The water circuit board assembly 12 includes a second water circuit connector 121 and a seal 122. The second water circuit connector 121 is detachably inserted into the plug-in port k1 of the first water circuit connector 114. The seal 122 is sleeved on the second water circuit connector 121 and located between the outer wall of the second water circuit connector 121 and the inner wall of the plug-in port k1. By integrating the seal 122 onto the second water circuit connector 121, the straight-through structure of the first water circuit connector 114 is simplified, eliminating the need for machining the groove of the inner wall seal 122, reducing machining steps and costs, and avoiding the problems of scale accumulation and bacterial growth. In addition, the replacement cycle of the filter element and the seal 122 can be independent, which is suitable for occasions where the filter element needs to be replaced frequently, and reduces the replacement frequency of the seal 122.

[0035] Furthermore, the sealing element 122 is fitted into the annular groove c1 on the outer wall of the second water connector 121, facilitating installation and disassembly. During insertion, it generates uniform radial compressive force, and its elastic deformation compensates for machining tolerances, ensuring stable sealing performance and reducing the risk of leakage. In addition, the second water connector 121 of the same specification can be adapted to insertion ports k1 of different depths, improving the versatility and adaptability of the water circuit board assembly 12.

[0036] Please refer to Figure 4 , Figure 6 and Figure 7 , Figure 6 yes Figure 1 An exploded view of the filter element assembly 11 shown. Figure 7 yes Figure 3 The diagram shows a cross-sectional view of the filter element assembly 11 along the B1-B2 position. In an optional embodiment, the filter element body 111 may include a filter element 1111, a filter element housing 1112, and a filter element end cap 1113. The filter element 1111 is assembled inside the filter element housing 1112; the filter element end cap 1113 is installed at one end of the filter element housing 1112 and has a connecting water channel s1 communicating with the filter element 1111; a first water connector 114 is installed on the filter element end cap 1113 and has a transition water channel s2, the two ends of which are respectively connected to the insertion port k1 and the connecting water channel s1.

[0037] The filter element end cap 1113 has multiple communicating water channels s1, which may include an inlet water channel, a purified water outlet water channel, and a wastewater outlet water channel. The filter element housing 1112 has a receiving cavity and an installation opening communicating with the receiving cavity. The filter element 1111 can be assembled in the receiving cavity through the installation opening. The filter element end cap 1113 can be installed at the installation opening to encapsulate the filter element 1111 in the filter element housing 1112 and the filter element end cap 1113. The filter element end cap 1113 can be snapped onto one end of the filter element housing 1112.

[0038] A water inlet chamber is formed between the filter element 1111 and the filter element housing 1112, and the water inlet chamber is connected to the water inlet channel. The filter element 1111 can be used to filter raw water. The filter element 1111 may include a reverse osmosis (RO) filter element. The filter element 1111 includes a reverse osmosis membrane structure a1, a water collection pipe a2, and a wastewater pipe a3. The water collection pipe a2 may be located inside the reverse osmosis membrane structure a1. The water collection pipe a2 has a purified water chamber inside, and multiple water passage holes are opened on the water collection pipe a2. The multiple water passage holes can communicate with the purified water chamber, and the purified water chamber can communicate with the purified water outlet channel. The filtered water through the reverse osmosis membrane structure a1 can enter the purified water chamber through the multiple water passage holes, and then flow out from the purified water outlet channel for user use.

[0039] The first water connector 114 is installed on the side of the filter element end cover 1113 opposite to the filter element 1111. The first water connector 114 has a transition water channel s2, and the two ends of the transition water channel s2 are connected to the insertion port k1 and the connecting water channel s1, respectively. The extension direction of the transition water channel s2 can be perpendicular to the axial direction of the filter element 1111, and the extension direction of the connecting water channel s1 can be parallel to the axial direction of the filter element 1111. In this way, by setting the first water connector 114 radially along the filter element 1111, the overall height of the filter element assembly 11 can be reduced.

[0040] For example, when raw water flows sequentially from the first inlet connector and the inlet channel into the inlet chamber between the filter cartridge housing 1112 and the filter cartridge 1111, the raw water can gradually fill the inlet chamber and enter the inlet end of the filter cartridge 1111. The filter cartridge 1111 starts to pass water and produces two parts of water, namely clean water and wastewater. At this time, the clean water enters the clean water chamber through the water passage of the water collection pipe a2 and finally flows out from the clean water outlet channel and the first outlet connector for user use; the wastewater is discharged sequentially through the wastewater pipe a3, the wastewater outlet channel and the first wastewater connector.

[0041] In an alternative embodiment, the first water connector 114 can be integrally formed with the filter element end cap 1113. The first water connector 114 and the filter element end cap 1113 can be an injection-molded integral structure, which can reduce the number of assembly parts in the filter element assembly 11.

[0042] Please refer to Figure 2 , Figure 4 , Figure 5 and Figure 8 , Figure 8 yes Figure 4 The schematic diagram of a partial A0 section of the filter element assembly shown illustrates an optional embodiment where the filter element assembly 11 may further include a one-way valve 112, which is fitted into the first water connector 114. When the second water connector 121 is inserted into the first water connector 114, its end abuts against the one-way valve 112, allowing the one-way valve 112 to open. When the second water connector 121 is not inserted into the first water connector 114, the one-way valve 112 is closed. When the second water connector 121 is inserted into the first water connector 114, its end opens the one-way valve 112, allowing water flow to proceed normally. When the second water connector 121 is pulled out, the one-way valve 112 automatically closes, effectively preventing liquid leakage from the filter element.

[0043] For example, the second water pipe connector 121 includes a water pipe and a push rod 1211 fixed to one end of the water pipe. The push rod 1211 is used to open the one-way valve 112. The water pipe has a water passage. The push rod 1211 has a flat plate-like structure and a pointed end to avoid affecting the normal flow of the water passage.

[0044] In one optional embodiment, the one-way valve 112 may include a valve seat 1121, a valve core 1122, a spring 1123, and an inner sealing ring 1124. The valve seat 1121 is installed in the first water connector 114 and has a flow cavity. The valve core 1122 is installed in the flow cavity. The valve core 1122 includes a valve stem portion and a valve head that are fixedly connected. The spring 1123 is sleeved on the outside of the valve stem portion, and the two ends of the spring 1123 abut against the valve seat 1121 and the valve head, respectively. The inner sealing ring 1124 is sleeved on the outside of the valve head portion and is located between the valve head and the valve seat 1121.

[0045] The one-way valve 112 may also have an outer sealing ring 1125, which is sleeved on the outside of the valve seat 1121 and located between the valve seat 1121 and the inner wall of the first water connector 114. Through the interference fit of the outer sealing ring 1125, the one-way valve 112 can be fixed in the first water connector 114. The valve seat 1121 is fixedly assembled inside the first water connector 114 by the outer sealing ring 1125, and the center of the valve seat 1121 has a through water flow channel (i.e., a flow cavity). The valve core 1122 adopts a split design, consisting of a valve column and a valve head connected together to form an integral structure, and is installed in the flow cavity of the valve seat 1121. The spring 1123, as an elastic element, is sleeved on the outside of the valve column, with its two ends forming elastic contact with the inner wall of the valve seat 1121 and the bottom of the valve head, respectively, providing a reliable restoring force for the valve core 1122. The inner sealing ring 1124 is tightly fitted onto the outer circumferential surface of the valve head, forming a dynamic sealing interface between the valve head and the inner wall of the valve seat 1121. This design ensures the sealing reliability of the check valve 112 in the closed state, maintains the smooth flow of water when the check valve 112 is open, and enables the valve core 1122 to automatically reset via the preload of the spring 1123.

[0046] Please refer to Figure 4 In one alternative embodiment, the end of the insertion port k1 has an inwardly facing chamfered structure r1. Thus, the beveled surface formed by the chamfered structure r1 provides progressive guidance when the second water connector 121 is inserted, helping the end of the second water connector 121 to smoothly slide into the insertion port k1, avoiding insertion jamming due to initial alignment deviation, thereby reducing assembly difficulty and improving insertion efficiency.

[0047] Furthermore, the chamfered structure r1 can reduce the right-angle contact between the second water connector 121 and the edge of the port when it is inserted, prevent the sealing ring from being cut by the edge of the insertion port k1 during the insertion process, and extend the service life of the seal 122.

[0048] Please refer to Figure 4 In one alternative embodiment, the extending direction of the connecting water channel s1 can be parallel to the axial direction of the filter element body 111, and the extending directions of the transition water channel s2 and the insertion port k1 can be parallel to the radial direction of the filter element body 111. In this way, the overall height of the filter element assembly 11 can be reduced.

[0049] Please refer to Figure 6 In an optional embodiment, the filter element assembly 11 may further include a decorative end cap 113, which is mounted on the outside of the filter element end cap 1113 and is detachably connected to the filter element end cap 1113. The connection between the decorative end cap 113 and the filter element end cap 1113 provides protection for at least a portion of the filter element end cap 1113 and the first water channel connector 114, and also enhances the aesthetics of the filter element assembly 11.

[0050] Please refer to Figure 4 and Figure 6 In an optional embodiment, the decorative end cap 113 has a loading / unloading handle 1131 at the end opposite to the filter housing 1112. Exemplarily, the loading / unloading handle 1131 can be a recessed type, employing an arc-shaped groove combined with a shielding plate design. The groove edges are smoothly transitioned, and the groove depth and shielding plate width are moderate for easy gripping. The loading / unloading handle 1131 is flush with the surface of the decorative end cap 113, reducing the overall height of the filter assembly and saving space.

[0051] When replacing or maintaining the filter element, the operator can easily remove the filter element assembly 11 from the equipment housing by hooking the loading and unloading handle 1131 with one hand.

[0052] This utility model embodiment also provides a water purification device, which may include: a device housing and a water purification device, a control component and a booster pump installed in the device housing; the water purification device includes the water purification device in any of the above embodiments, the control component is electrically connected to the booster pump, the booster pump is connected to the water purification device, and the booster pump can be connected to the second water circuit connector in the water circuit board assembly through a water circuit adapter structure.

[0053] It should be noted that the dimensions of the areas may have been exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element is referred to as "on top of" another element, it can be directly on the other element, or there may be intermediate elements. Additionally, it is understood that when an element is referred to as "below" another element, it can be directly below the other element, or there may be more than one intermediate element. Furthermore, it is also understood that when an element is referred to as "between" two elements, it can be the only layer between the two elements, or there may be more than one intermediate element. Similar reference numerals throughout indicate similar elements.
