[0042] like Figures 1 to 5 As shown, this embodiment provides a water circuit board integrated component, including a water circuit board component 200 and a bracket component 300 on which a power-conducting device is installed. A filter element insertion structure 201 is provided on one side of the water circuit board component 200. The filter element insertion structure 201 is used for inserting the filter element component 500. In specific applications, after the filter element component 500 is installed from the main housing 100 of the water purifier, the interface at the rear end of the filter element component 500 is connected to the filter element insertion structure 201, so that the interface of the filter element component 500 is connected to the water circuit board component 200. The first end of the bracket component 300 is connected to the water circuit board component 200, and the bracket component 300 and the water circuit board component 200 are arranged perpendicularly to each other. The bracket component 300 and the filter cartridge insertion structure 201 are located on the same side of the water circuit board component 200, which can realize an integrated design of water and electricity separation. The water circuit board component 200 integrates water circuit related connection structures, and the bracket component 300 integrates power supply devices, which may include a power module 310, a booster pump 320, and a control circuit board 330. The water circuit board component 200 and the bracket component 300 are integrated and connected as one body and assembled in the main housing 100. There is no need to set up components such as a middle frame in the main housing 100. Its structure is compact, easy to assemble, and low in cost.

[0043] In practical applications, the main housing 100 of the water purifier may have an installation opening 101 on its rear side. The water circuit board component 200 and the bracket component 300 can be inserted into the main housing 100 as a whole through the installation opening 101. The water circuit board component 200 can serve as the outer side of the water purifier and cover the installation opening 101. The filter element component 500 can be inserted into the main housing 100 through the front panel 102 on the front side of the housing and plugged into the filter element insertion structure 201. During installation, the filter element component 500 can be connected to the filter element insertion structure 201 (filter element socket) by means of screws, threads, or clips, so that the water circuit between the filter element component 500 and the water circuit board component 200 is connected. In this embodiment, there are two filter element components 500, namely a five-in-one filter element and an RO filter element.

[0044] Specifically, the water channel plate component 200 and the bracket component 300 are connected in an "L" shape, with the bracket component 300 positioned near one end of the water channel plate component 200; the water channel plate component 200 can be designed longitudinally, and the bracket component 300 is laterally connected to the bottom of one side of the water channel plate component 200, such as... Figure 3As shown, an L-shaped integrated structure is formed. This L-shaped integrated structure can be inserted into and fixed to the main housing 100 as a whole. The bracket component 300 can be positioned close to the bottom of the main housing 100 for good stability. Alternatively, the bracket component 300 can be designed close to the inner top of the main housing 100. Even if the filter element component 500 leaks at its interface, it will not affect electrical components such as the power module 310 and the booster pump 320, ensuring high reliability. During installation, the filter element component 500 can be placed horizontally with the front panel 102 of the main housing 100 facing forward for easy replacement of the filter element component 500.

[0045] Alternatively, the water circuit board component 200 and the bracket component 300 can also be connected in a (side) "T" shape, with the bracket component 300 positioned near the center of one side of the water circuit board component 200. The water circuit board component 200 can be designed longitudinally, with the bracket component 300 laterally connected to the center of one side of the water circuit board component 200, forming a side "T" shaped integrated structure. This side "T" shaped integrated structure can be integrally inserted into and fixed to the main housing 100. The front end of the bracket component 300 can abut against the inner side of the front panel 102 of the main housing 100. Two sets of filter cartridges 500 can be respectively positioned on both sides of the bracket component 300. During installation of the water purifier, the filter cartridges 500 can be placed longitudinally, i.e., with the front panel 102 of the main housing 100 facing upwards, facilitating the replacement of the filter cartridges 500.

[0046] Specifically, the bracket component 300 has a power mounting position for mounting the power module 310 and a booster pump mounting position for mounting the booster pump 320, which are arranged sequentially along the length of the bracket component 300. The bracket component 300 has a first end and a second end along its length. The first end of the bracket component 300 is fixedly connected to the water circuit board component 200. The power mounting position is close to the first end of the bracket component 300, and the booster pump mounting position is close to the second end of the bracket component 300. By utilizing the space along the length of the filter element component 500, the power module 310 and the booster pump 320 are reasonably arranged, so that the overall length of the water purifier is only slightly longer than the length of the filter element component 500.

[0047] Specifically, the power supply mounting position is close to the water circuit board component 200, and a partition 340 is provided at the power supply mounting position. The spaces on both sides of the partition 340 are connected to the water circuit board component 200. The power module 310 is fixed to one side of the partition 340, and the booster pump 320 is connected to the interface of the water circuit board component 200 through a connecting pipe 321. The connecting pipe 321 is located on the other side of the partition 340. Even if there is water leakage at the connecting pipe 321, the power module 310 will not be directly affected by the water leakage, resulting in better reliability.

[0048] Specifically, at least two power module fixing posts 341 are provided on one side of the partition 340. The power module fixing posts 341 are provided with screw holes. The power module 310 is fixed with an ear. The ear has a hole for the power module locking member to pass through. The power module 310 is fixed to the power module fixing posts 341 by the power module locking member (screw). The bottom of the power module 310 is suspended relative to the bracket component 300. In this way, the power module 310 is suspended relative to the bracket component 300 and the inner bottom of the main housing 100. Even if water accumulates inside the main housing 100 due to leakage or other reasons, the power module 310 will not be directly affected, and the safety and reliability will be better.

[0049] Specifically, a settling tank is provided at the mounting position of the booster pump, the booster pump 320 is partially accommodated in the settling tank, and the booster pump 320 is fixed to the mounting position of the booster pump by the mounting bracket 322, which has good structural reliability.

[0050] Specifically, the mounting bracket 322 includes a support plate 326, which is fixed to the outside of the booster pump 320. The booster pump 320 can be fixed to the support plate 326 with screws. The support plate 326 is semi-cylindrical and is disposed in the settling tank. The two sides of the support plate 326 extend outward to form protruding edges 323, which are located on both sides outside the settling tank. The protruding edges 323 are provided with booster pump mounting holes. The bracket component 300 is provided with a booster pump fixing post, which is disposed below the booster pump mounting holes. The support plate 326 is connected to the booster pump fixing post by a booster pump locking component 324 (screws). A buffer sleeve 325 (rubber sleeve) is provided between the support plate 326 and the booster pump fixing post. The buffer sleeve 325 is fitted onto the booster pump locking component 324, resulting in good buffering effect for the booster pump 320.

[0051] Specifically, the booster pump mounting position has a high-voltage wiring mounting position 331 and a low-voltage wiring mounting position 332 on both sides along its width. The bracket component 300 has cable tie through holes 333 on both sides, allowing for separate wiring of high-voltage and low-voltage lines. The wiring is secured with cable ties, ensuring high reliability. In practical applications, the water circuit board component 200 can be equipped with a TDS (Total Dissolved Solids) sensor and an NTC (Negative Temperature Coefficient thermometer) temperature sensor. A control circuit board 330 is located at the second end of the bracket component 300. The TDS sensor and NTC temperature sensor can be connected to the control circuit board 330 via cables from the low-voltage wiring mounting position 332. The power cord of the booster pump 320 can be located at the high-voltage wiring mounting position 331.

[0052] This invention also provides a water purifier, including a main housing 100 and the aforementioned water circuit board integrated component, which is connected to the main housing 100.

[0053] Specifically, such as Figures 5 to 8 As shown, the back of the main housing 100 is a mounting opening 101. The water circuit board integrated component is inserted into the main housing 100 through the mounting opening 101, and the water circuit board component 200 closes the mounting opening 101. In this embodiment, the back of the main housing 100 is entirely set as a mounting opening 101, and all four sides of the water circuit board component 200 are connected to the inner sidewall of the main housing 100. The main housing 100 adopts an integrally formed structure. Its front panel 102 is provided with filter element mounting holes 1021, and the back is a fully open design. The water circuit board integrated component is directly connected to the inner side of the main housing 100. Its structure is compact, easy to assemble, and has low production cost.

[0054] Specifically, the main housing 100 has inner side ribs on opposite sides, which are arranged along the insertion direction of the water channel plate integrated component. The water channel plate component 200 and / or the bracket component 300 have mating parts that connect with the inner side ribs. Specifically, the two opposite sidewalls of the main housing 100 are a first sidewall 103 and a second sidewall 104, respectively. The first sidewall 103 and the second sidewall 104 of the main housing 100 are respectively provided with a first reinforcing rib 111 and a second reinforcing rib 112. The inner side ribs include the first reinforcing rib 111 and the second reinforcing rib 112. The first reinforcing rib 111 and the second reinforcing rib 112 both extend along the mounting opening 101 toward the front panel 102 of the main housing 100. The water channel plate component 200 and the bracket component 300 are provided with a first limiting groove 211 and a second limiting groove 212 on both sides. The first limiting groove 211 engages with the first reinforcing rib 111, and the second limiting groove 212 engages with the second reinforcing rib 112. This ensures excellent stability during installation of each component, eliminating the need for excessive screws and clips, thus improving assembly efficiency and reducing costs. Furthermore, the reinforcing ribs effectively enhance the structural strength of the main housing 100, preventing deformation and increasing structural reliability.

[0055] Specifically, in this embodiment, the lower sidewall (bottom wall) of the main housing 100 is defined as the third sidewall 105, and the upper sidewall (top wall) of the main housing 100 is defined as the fourth sidewall 106. The bottom of the bracket component 300 is connected to the third sidewall 105 of the main housing 100. The third sidewall 105 of the main housing 100 is provided with a third reinforcing rib 213, which extends into the main housing 100 along the mounting opening 101. The bracket component 300 is provided with multiple protruding ribs 311, which are staggered with the third reinforcing rib 213. Alternatively, a limiting groove is formed between two protruding ribs 311, and the third reinforcing rib 213 is engaged in the limiting groove, resulting in good installation and positioning. The bottom of the bracket component 300 has a certain gap with the inner bottom of the main housing 100, so that even if water accumulates inside the main housing 100 due to leakage, the water can be prevented from directly soaking the electrical components on the bracket component 300. The top of the water circuit board component 200 is provided with a fourth limiting groove 214, and the fourth side wall 106 of the main housing 100 is provided with a fourth reinforcing rib 114. The fourth reinforcing rib 114 extends into the main housing 100 along the mounting opening 101. The fourth reinforcing rib 114 is engaged with the fourth limiting groove 214. In this way, the four directions of the outer periphery of the water circuit board integrated component are assembled and constrained by the rib groove cooperation structure, its internal structure is stable, and the water circuit board component 200 is completely covered by the mounting opening 101 on the back of the main housing 100.

[0056] Specifically, such as Figures 5 to 9 As shown, the first sidewall 103 and the second sidewall 104 of the main housing 100 are provided with screw through holes 107 near the mounting opening 101. Countersunk screws are provided in the screw through holes 107, and these countersunk screws are threaded onto both sides of the water circuit board component 200 to prevent the integrated water circuit board component from exiting the mounting opening 101. A patch (not shown in the figure) is provided at the countersunk screw location. The patch can be flush with the first sidewall 103 and the second sidewall 104 of the main housing 100. The color, surface texture, and pattern of the patch can be consistent with the outer side of the main housing 100 to ensure good product appearance consistency.

[0057] In this embodiment, one end of the bracket component 300 is provided with a support groove 351. The water circuit board component 200 is partially inserted into the support groove 351 and limited by the support groove 351. The bracket component 300 is provided with locking members on both sides and / or the bottom of the support groove 351. The locking members are used to lock the water circuit board component 200 into the support groove 351 of the bracket component 300. The locking members can be screws. The lower end of the water circuit board component 200 is inserted into the support groove 351 of the bracket component 300 and locked together by the locking members to form a water and electricity assembly module (i.e., water circuit board integrated component), which has good connection reliability.

[0058] Specifically, the side of the water channel plate component 200 facing the inner cavity of the main housing 100 is the water channel connection surface 221, and the opposite side is the outer appearance surface 222. The water channel connection surface 221 is provided with a filter element insertion structure 201, which is used for inserting the filter element component 500. The main housing 100 has a filter element mounting position, which is located above the bracket component 300.

[0059] Specifically, the water channel plate component 200 includes a first cover plate 10 and a second cover plate 20, which are fixedly connected to each other to form a water channel chamber; one end of the first cover plate 10 is inserted into the support groove 351, and the side of the second cover plate 20 facing the first cover plate 10 is attached to the end face of the first end of the bracket component 300, which makes it easy to position during docking and helps to improve assembly accuracy.

[0060] Specifically, the portion of the first cover plate 10 inserted into the support groove 351 is the insertion part, and the portion of the first cover plate 10 located outside the support groove 351 is the exposed part. The side wall of the insertion part is recessed inward relative to the side wall of the exposed part. The two opposite outer sides of the exposed part and the two opposite outer sides of the bracket component 300 are all abutted against the inner side wall of the main housing 100, so that the outer side of the water channel plate component 200 and the outer side of the bracket component 300 can be flush, avoiding the formation of a stepped structure between the outer side of the water channel plate component 200 and the outer side of the bracket component 300. When the whole is installed in the main housing 100, the outer side of the water channel plate component 200 and the outer side of the bracket component 300 can simultaneously abut against the opposite first side wall 103 and second side wall 104 of the main housing 100, resulting in better structural reliability.

[0061] Specifically, the two opposite outer surfaces of the exposed portion are provided with limiting slots, the limiting slots are adjacent to the insertion portion, and one side wall of the limiting slot is flush with the upper end face of the bracket component 300; the inner side of the main housing 100 is provided with a limiting protrusion, the limiting protrusion is inserted into the limiting slot, and the limiting protrusion abuts against the upper end face of the bracket component 300, thereby limiting the installation of the water circuit board component 200 and the bracket component 300.

[0062] In this embodiment, the back of the main housing 100 has an installation opening 101. The water channel plate integrated component is integrally inserted into the main housing 100 through the installation opening 101, and the water channel plate component 200 closes the installation opening 101. In this embodiment, the back of the main housing 100 is integrally configured as the installation opening 101, and all four sides of the water channel plate component 200 are connected to the inner sidewall of the main housing 100. The main housing 100 adopts an integrally formed structure, with filter element mounting holes 1021 on its front side and a fully open design on its back side. The water channel plate integrated component is directly connected to the inner side of the main housing 100, resulting in a compact structure, convenient assembly, and low production cost.

[0063] Specifically, the two opposing sidewalls of the main housing 100 are a first sidewall 103 and a second sidewall 104. The opposing first sidewall 103 and second sidewall 104 of the main housing 100 are respectively provided with a first reinforcing rib 111 and a second reinforcing rib 112, and at least one set of the first reinforcing rib 111 and the second reinforcing rib 112 serves as the aforementioned limiting protrusion. The first reinforcing rib 111 and the second reinforcing rib 112 both extend along the mounting opening 101 toward the front panel 102 of the main housing 100. The water channel plate component 200 and the bracket component 300 are provided with limiting slots (a first limiting slot 211 and a second limiting slot 212) on both sides. The first limiting slot 211 is engaged with the first reinforcing rib 111, and the second limiting slot 212 is engaged with the second reinforcing rib 112. The installation of each component is stable, and the design does not require too many screws or clips, which is conducive to further improving assembly efficiency and reducing costs. Furthermore, the addition of reinforcing ribs effectively improves the structural strength of the main shell 100, prevents deformation of the main shell 100, and enhances structural reliability.

[0064] Specifically, in this embodiment, the lower sidewall (bottom wall) of the main housing 100 is defined as the third sidewall 105, and the upper sidewall (top wall) of the main housing 100 is defined as the fourth sidewall 106. The first sidewall 103 and the second sidewall 104 are arranged facing each other, and the third sidewall 105 and the fourth sidewall 106 are arranged facing each other. The first sidewall 103, the second sidewall 104, the third sidewall 105, and the fourth sidewall 106 together form a rectangular frame. The front panel 102 of the main housing 100 is integrally connected to the first sidewall 103, the second sidewall 104, the third sidewall 105, and the fourth sidewall 106, forming a housing structure with an opening on the rear side. The bottom of the bracket component 300 is connected to the third side wall 105 of the main housing 100. The third side wall 105 of the main housing 100 is provided with a third reinforcing rib 213, which extends into the main housing 100 along the mounting opening 101.

[0113] When water flows through the connector 147 into the inlet valve 34, it flows to the first booster pump interface 144, and then through the first booster pump interface 144 and the second booster pump interface 145 into the booster pump.

This can reduce the space occupied by the above-mentioned multiple guide channel structures 40 on the first cover plate 10. Specifically, since the guide channel structure 40 protrudes from the second surface 12, the thickness of the first cover plate 10 can be set to be smaller, which can reduce the space occupied by the water circuit board component 200 in the water purifier 200, thereby achieving the purpose of reducing the volume of the water purifier 200.

[0117] Understandably, the first guide channel 41 is used to connect the fourth filter element interface 134 and the connection port 147, the second guide channel 42 is used to connect the third booster pump interface 146 and the seventh filter element interface 143, and the third guide channel 43 is used to connect the third filter element interface 133 and the sixth filter element interface 142.

Specifically, the inlet 1140 is connected to the first filter element interface 131, so that when the water flows into the first cover plate 10, it can flow directly into the composite filter element 32. The pure water outlet 1150 is connected to the second filter element interface 132, and the water discharged from the pure water outlet 1150 is pure water discharged after being filtered by activated carbon. The wastewater outlet 1160 is connected to the fifth filter element interface 141 through the fourth guide channel 44, so that the wastewater generated by the RO filter element 31 is discharged to the wastewater outlet 1160 through the fourth guide channel 44 to discharge the wastewater in the RO filter element 31.

[0122] The water flow direction in the aforementioned cover plate is as follows: water enters the water circuit board component 200 through the inlet 1140, then enters the composite filter element 32 and is filtered by the PP membrane. After filtration, the PP membrane is discharged through the fourth filter element interface 134, then flows through the first guide channel 41 into the connection port 147, and then into the inlet valve 34. After flowing out of the inlet valve 34, the water flows to the first booster pump interface 144, then to the second booster pump interface 145, and enters the booster pump 320 for pressurization through the second booster pump interface 145, and then is discharged through the third booster pump interface 146. After pressurizing the water flow, the pressurized water flows through the second guide channel 42 to the seventh filter element interface 143, and then enters the RO filter element 31. After filtration by the RO filter element 31, pure water is discharged from the sixth filter element interface 142, and wastewater is discharged from the fifth filter element interface 141. The pure water in the sixth filter element interface 142 flows through the third guide channel 43 to the third filter element interface 133 and enters the activated carbon filter layer in the composite filter element 32 for filtration. After flowing out of the activated carbon filter layer, it is discharged from the water purifier 200 through the pure water outlet 1150 and is ready for drinking. The wastewater generated in the fifth filter element interface 141 is discharged through the fourth guide channel 44 to the wastewater outlet 1160 and discharged from the water purifier 200.

[0123] In some embodiments, the first guide groove 41, the second guide groove 42, the third guide groove 43, and the fourth guide groove 44 all protrude from the second surface 12.

[0124] Understandably, the first guide groove 41, the second guide groove 42, the third guide groove 43, and the fourth guide groove 44 all protrude from the second surface 12. This is to facilitate their cooperation with the guide member 50. The guide member 50 can be inserted into the guide groove. When the guide member 50 is inserted into the above-mentioned guide grooves, the first cover plate 10 and the second cover plate 20 can also be fitted together to improve the tightness of the fit between the guide member 50 and the guide groove.

[0125] In some embodiments, both the first base 13 and the second base 14 have a limiting portion 60, which protrudes from the first surface 11.

[0126] Understandably, both the first base 13 and the second base 14 have a limiting part 60, which protrudes from the first surface 11. This is to facilitate the installation of the RO filter element 31 and the composite filter element 32 onto the first base 13 and the second base 14. Specifically, both the first base 13 and the second base 14 protrude from the second surface 12. This allows the first base 13 and the second base 14 to provide positioning for the composite filter element 32 and the RO filter element 31 during installation, thus facilitating the installation of the RO filter element 31 and the composite filter element 32.
