[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] The terms "first", "second", etc. in the specification and claims of the present invention and the above - mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non - exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0042] Referring to "embodiment" or "implementation manner" herein means that a specific feature, structure or characteristic described in connection with the embodiment or implementation manner can be included in at least one embodiment of the present invention. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0043] The water purification devices in the related art are all set for multi-stage filtration. Municipal water is filtered through multiple filter elements. However, the filter elements need to be connected through a water circuit board, which usually includes a board body, an upper cover, and a filter element seat. Each part is connected by secondary encapsulation and secondary injection molding, which makes the size of the water circuit board larger, and further makes the structure of the water purifier larger and more complex.

[0044] In view of this, this embodiment provides a cover plate 100 and a water purifier 200. The cover plate 100 can reduce the volume of the water purifier 200.

[0045] Please refer to Figure 1 and Figure 2 , a cover plate 100, including: The cover plate 100 includes a first surface 10 and a second surface 20 arranged opposite to each other;

[0046] The first surface 10 is provided with a first mounting portion 11, a second mounting portion 12, and a third mounting portion 13. Among them, the first mounting portion 11, the second mounting portion 12, and the third mounting portion 13 are all provided with interface components 30. The second surface 20 is provided with a flow guiding groove structure 40, and the interface components 30 are communicated with the flow guiding groove structure 40.

[0047] By arranging the first mounting portion 11, the second mounting portion 12, and the third mounting portion 13 on the first surface 10 of the above cover plate 100, and arranging interface components 30 on the first mounting portion 11, the second mounting portion 12, and the third mounting portion 13. The interface components 30 are arranged on the first surface 10, and a flow guiding groove structure 40 is arranged on the second surface 20. By connecting the interface components 30 arranged on the first mounting portion 11, the second mounting portion 12, and the third mounting portion 13 through the flow guiding groove structure 40, after installing the filtration devices in the water purifier 200 to the corresponding positions, the various water purification devices can be interconnected with each other, and thus the upper cover and the filter element seat in the traditional water circuit board can be omitted, so as to achieve the purpose of reducing the volume of the water purifier 200.

[0048] It can be understood that the interior of the cover plate 100 is a cavity, which makes the cover plate 100 have multiple sides. One of the sides has a first surface 10 and a second surface 20 arranged opposite to each other. By arranging a first mounting portion 11, a second mounting portion 12, and a third mounting portion 13 on the first surface 10, and arranging an interface component 30 on the first mounting portion 11, the second mounting portion 12, and the third mounting portion 13, and arranging a plurality of diversion groove structures 40 (the diversion grooves are located in the cavity) on the second surface 20, the plurality of diversion grooves connect the interface components 30 so that water can flow between the interface components 30. The interface component 30 is used to connect a water purification device. In this way, the water purification device can be directly mounted on the mounting plate. Compared with the water purifier 200 in the related art, in the present solution, when the cover plate 100 is applied to the water purifier 200, the cover plate 100 and the upper cover can be omitted, and the integrated cover plate 100 has a higher integration degree, which can eliminate the assembly tolerance between components. In this way, the purpose of further reducing the water purifier 200 can be achieved, and the integrated cover plate 100 can also reduce the steps during assembly to improve the production efficiency of the water purifier 200.

[0049] Please refer to Figure 1 and Figure 2 , in some embodiments, it further includes: a first base 50 and a second base 53;

[0050] The first base 50 is disposed on the first mounting portion 11, and the second base 53 is disposed on the second mounting portion 12.

[0051] It can be understood that by arranging the first base 50 on the first mounting portion 11 and the second base 53 on the second mounting portion 12, the first base 50 and the second base 53 can play a positioning role for the water purification device mounted on the cover plate 100, and can also facilitate the direct mounting of the water purification device to the first base 50 and the second base 53, so that the water purification device is in direct contact with the first base 50 and the second base 53. In this way, it is convenient to install or disassemble the water purification device in the water purifier 200.

[0052] Please refer to Figure 1 and Figure 2 , in some embodiments, the interface component 30 includes: a first interface component 31, a second interface component 32, and a third interface component 33;

[0053] The first interface component 31 is disposed on the first base 50, and the first interface component 31 is in communication with the first base 50; the second interface component 32 is disposed on the second base 53, and the second base 53 is in communication with the second interface component 32; the third interface component 33 is disposed on the third interface component 33, and the third base is in communication with the third interface component 33;

[0054] Among them, the first interface component 31, the second interface component 32, and the third interface component 33 are all connected to the flow guide groove structure 40.

[0055] It can be understood that the first interface component 31 is arranged on the first base 50. Among them, the first interface component 31 is connected to the flow guide groove structure 40, and the first interface component 31 can be connected to the water purification device arranged on the first base 50. In this way, water flow can enter the first interface component 31 through the flow guide groove structure 40.

[0056] After that, it enters the water purification device arranged on the first base 50 through the first interface component 31 to purify the water flow in the flow guide groove; the second interface component 32 is arranged on the second base 53. Among them, the second interface component 32 is connected to the flow guide groove structure 40, and the second interface component 32 can be connected to the water purification device arranged on the second base 53. In this way, water flow can enter the second interface component 32 through the flow guide groove structure 40. After that, it enters the water purification device arranged on the second base 53 through the second interface component 32 to purify the water flow in the flow guide groove; the third interface component 33 is arranged on the third base. Among them, the third interface component 33 is connected to the flow guide groove structure 40, and the third interface component 33 is used to be connected to the water purification device arranged on the third base. In this way, water flow can enter the third interface component 33 through the flow guide groove structure 40. After that, it enters the water purification device arranged on the third base through the third interface component 33 to purify the water flow in the flow guide groove; since the flow guide groove structure 40 connects the first interface component 31, the second interface component 32, and the third interface component 33 to each other, in this way, it enables the water flow to flow between the first interface component 31, the second interface component 32, and the third interface component 33, so that the water flow can achieve the purpose of water purification when flowing between the water purification devices.

[0057] Please refer to Figure 1 and Figure 2 , in some embodiments, the flow guide groove structure 40 includes: a first flow guide groove 41, a second flow guide groove 42, a third flow guide groove 43, and a fourth flow guide groove 44;

[0058] The first flow guide groove 41, the second flow guide groove 42, the third flow guide groove 43, and the fourth flow guide groove 44 all protrude from the second surface 20.

[0059] It can be understood that the first diversion groove 41, the second diversion groove 42, the third diversion groove 43, and the fourth diversion groove 44 are all structures protruding from the second surface 20. This can reduce the space occupied by the above-mentioned multiple diversion grooves on the water circuit board. Specifically, the diversion grooves protrude from the second surface 20, so that the thickness of the cover plate 100 can be set to be smaller, and thus the space occupied by the cover plate 100 in the water purifier 200 can be reduced, so as to achieve the purpose of reducing the volume of the water purifier 200.

[0060] It can be understood that the above-mentioned diversion groove structure 40 protruding from the second surface 20 can also reduce the overall weight of the cover plate 100. Specifically, the inside of the cover plate 100 is a cavity, and baffles are provided at the places where the diversion grooves need to be set. The diversion groove structure 40 is formed by the baffles, so that only the protruding structure needs to be set at the part where the diversion groove structure 40 needs to be opened, which reduces the weight of the water circuit board compared with the traditional water circuit board.

[0061] Please refer to Figure 1 , Figure 2 and Figure 6 and Figure 7 , in some embodiments, the third interface component 33 includes: a first booster pump interface 331, a second booster pump interface 332, a third booster pump interface 333, and a connection port 334;

[0062] An inlet valve 52 and a booster pump 51 are provided on the third installation part 13. The connection port 334 and the first booster pump interface 331 are both connected to the inlet valve 52, and the second booster pump interface 332 and the third booster pump interface 333 are both connected to the booster pump 51.

[0063] It can be understood that the third interface component 33 includes: a first booster pump interface 331, a second booster pump interface 332, a third booster pump interface 333, and a connection port 334. Among them, the connection port 334 and the first booster pump interface 331 are communicated with the inlet valve 52, and the second booster pump interface 332 and the third booster pump interface 333 are communicated with the booster pump 51. After the water flow enters the connection port 334, it flows through the inlet valve 52 to the second booster pump interface 332, and enters the booster pump 51. The booster pump 51 pressurizes the water flow and then flows out of the booster pump 51 and flows to the third booster pump interface 333 to achieve the pressurization of the water flow.

[0064] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 7 , in some embodiments, the second interface component 32 includes: a first filter element interface 321, a second filter element interface 322, and a third filter element interface 323;

[0065] The second base 53 is provided with an RO filter element 54, and the first filter element interface 321, the second filter element interface 322, and the third filter element interface 323 are all communicated with the RO filter element 54; the second diversion groove 42 is used for communicating the third booster pump interface 333 with the third filter element interface 323.

[0066] It can be understood that the second interface assembly 32 includes: a first filter element interface 321, a second filter element interface 322, and a third filter element interface 323. The above-mentioned first filter element interface 321, second filter element interface 322, and third filter element interface 323 are all used for communicating with the RO filter element 54;

[0067] Among them, the RO filter element 54 is provided with a filter element water inlet, a filter element water outlet, and a filter element wastewater outlet. When the RO filter element 54 is installed on the second base 53, the RO filter element water inlet 57 is communicated with the third filter element interface 323, the RO filter element water outlet is communicated with the second filter element interface, and the RO filter element wastewater outlet is communicated with the first filter element interface 321.

[0068] Please refer to Figure 1 、 Figure 2 and Figure 4 and Figure 7 , in some embodiments, the first interface assembly 31 includes: a fourth filter element interface 311, a fifth filter element interface 312, a sixth filter element interface 313, and a seventh filter element interface 314;

[0069] The first base 50 is provided with a composite filter element 55, and the fourth filter element interface 311, the fifth filter element interface 312, the sixth filter element interface 313, and the seventh filter element interface 314 are all communicated with the composite filter element 55;

[0070] The first diversion groove 41 is used for communicating the fourth filter element interface 311 and the connection port 334, and the third diversion groove 43 is used for communicating the second filter element interface 322 with the sixth filter element interface 313.

[0071] It can be understood that the first interface assembly 31 includes: a fourth filter element interface 311, a fifth filter element interface 312, a sixth filter element interface 313, and a seventh filter element interface 314. Among them, the composite filter element 55 includes a first composite filter element water inlet, a composite filter element drain outlet, a second composite filter element water inlet, and a composite filter element water outlet; when the filter element is installed on the first base 50, the first composite filter element water inlet is installed on the fourth filter element interface 311, the composite filter element drain outlet is installed on the seventh filter element interface 314, the second composite filter element water inlet is installed on the sixth filter element interface 313, and the composite filter element water outlet is installed on the fifth filter element interface 312. In this way, the cooperation between the filter element and the first base 50 can be realized, and the first interface assembly 31 can be communicated with the composite filter element 55.

[0072] It is understandable that the composite filter element 55 is provided with a PP membrane and an activated carbon layer. Among them, the PP membrane is used to filter large particulate matters in the water flow, and the activated carbon is used to remove odors. After the water flow is filtered by the PP membrane, it will enter the RO filter element 54 for filtration, and then enter the activated carbon layer for filtration to remove odors.

[0073] Please refer to Figure 2 , in some embodiments, the cover plate 100 has a water inlet 57, a pure water outlet 58, and a wastewater outlet 59;

[0074] The water inlet 57 is communicated with the fourth filter element interface 311, the pure water outlet 58 is communicated with the fifth filter element interface 312, and the fourth diversion groove 44 is used to communicate the first filter element interface 321 and the wastewater outlet 59.

[0075] It is understandable that the water inlet 57 is communicated with the fourth filter element interface 311, so that when the water flow enters the cover plate 100, it can directly flow into the composite filter element 55. The pure water outlet 58 is communicated with the fifth filter element interface 312, and the fifth filter element interface 312 is the pure water discharged after the water flow passes through the activated carbon filtration. The wastewater outlet 59 is communicated with the first filter element interface 321 through the fourth diversion groove, so that the wastewater generated by the RO filter element 54 is discharged to the wastewater outlet 59 through the fourth diversion groove 44 to discharge the wastewater in the RO filter element 54.

[0076] It is understandable that the cover plate 100 has a water inlet 57, a pure water outlet 58, and a wastewater outlet 59. The water inlet 57, the pure water outlet 58, and the wastewater outlet 59 are arranged on the part of the cover plate 100 close to the first base 50, which is to facilitate the water inlet of the composite filter element 55 and the discharge of the water flow after secondary purification, so that the length of the water path in the cover plate 100 can be reduced.

[0077] Please refer to Figure 2 and Figure 3 , in some embodiments, it further includes: a high-pressure switch 56;

[0078] The high-pressure switch 56 is arranged in the third diversion groove 43, and the high-pressure switch 56 is used to control the outlet water pressure.

[0079] It is understandable that the high-pressure switch 56 is arranged in the third diversion groove 43, and is used to adjust the water pressure entering the composite filter element 55 and the water pressure of the pure water outlet 58. Specifically, when the water purifier 200 works, if the outlet water flow rate is too fast or a water hammer phenomenon occurs, the high-pressure switch 56 can cut off the power supply in time to avoid damage to the water purifier 200 and the pipeline caused by the water hammer.

[0080] The water flow direction in the above-mentioned cover plate 100 is as follows: Water flows into the cover plate 100 through the water inlet 57, then enters the composite filter element 55 and is filtered by the pp membrane. After filtration by the pp membrane, it is discharged through the seventh filter element interface 314, then flows into the connection port 334 through the first diversion groove 41, and enters the water inlet valve 52. After the water flows out of the water inlet valve 52, it flows to the first booster pump interface 331, then to the second booster pump interface 332, enters the booster pump 51 through the second booster pump interface 332 for boosting, and then is discharged through the third booster pump interface 333 to complete the boosting of the water flow. The boosted water flow flows to the third filter element interface 323 through the second diversion groove 42, enters the RO filter element 54 through the third filter element interface 323. After the RO filter element 54 filters the water flow, a part is discharged from the second filter element interface 322 and the first filter element interface 321. The second filter element interface flows to the activated carbon filter layer in the composite filter element 55 through the third diversion groove 43 for filtration. After flowing out of the activated carbon filter layer, it is discharged from the pure water outlet 58 of the water purifier 200 and can be drunk.

[0081] When the water flow passes through the RO filter element 54 for filtration, waste water will also be generated. The waste water is discharged through the waste water outlet 59 of the RO filter element 54, and then the waste water is discharged from the water purifier 200 through the fourth diversion groove 44.

[0082] Please refer to Figure 8 , the present utility model also provides a water purifier 200, and the water purifier 200 includes:

[0083] A housing 210, and the above-mentioned cover plate 100;

[0084] One side of the housing 210 has an opening 220, and the cover plate 100 is arranged in the opening 220.

[0085] An opening 220 is arranged on one side of the above-mentioned water purifier 200, and the cover plate 100 is arranged in the opening 220. After the cover plate 100 is arranged in the opening 220, the cover plate 100 can not only be used as a water circuit board, but also can be used as a side plate of the water purifier 200, so that the volume of the water purifier 200 can be greatly reduced. Specifically, the above-mentioned cover plate 100 is provided with a first installation part 11, a second installation part 12, and a third installation part 13 on the first surface 10, and an interface assembly 30 is arranged on the first installation part 11, the second installation part 12, and the third installation part 13. The interface assembly 30 is arranged on the first surface 10, and a diversion groove structure 40 is arranged on the second surface 20. The interface assembly 30 arranged on the first installation part 11, the second installation part 12, and the third installation part 13 is connected through the diversion groove structure 40. After the filtering devices in the water purifier 200 are installed at corresponding positions, the various water purification devices can be interconnected, and thus the upper cover and the filter element seat in the traditional water circuit board can be omitted, so as to achieve the purpose of reducing the volume of the water purifier 200.

[0086] Please refer to Figure 4 and Figure 5 In some embodiments, the first base 50 and the second base 53 both have a limiting portion 60, and the limiting portions 60 both protrude from the first surface 10.

[0087] It can be understood that both the first base 50 and the second base 53 have a limiting portion 60, and the limiting portion 60 protrudes from the first surface 10. This is to facilitate the installation of the RO filter element 54 and the composite filter element 55 onto the first base 50 and the second base 53. Specifically, both the first base 50 and the second base 53 protrude from the second surface 20. In this way, when installing the composite filter element 55 and the RO filter element 54, the first base 50 and the second base 53 can provide positioning for them, facilitating the installation of the RO filter element 54 and the composite filter element 55.

[0088] In the present utility model, the mention of "embodiment" or "embodiment mode" means that the specific features, structures or characteristics described in combination with the embodiment can be included in at least one embodiment of the present utility model. The appearance of the phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art understand explicitly and implicitly that the embodiments described in the present utility model can be combined with other embodiments. In addition, it should also be understood that the features, structures or characteristics described in each embodiment of the present utility model can be combined arbitrarily without contradiction to form another embodiment that does not deviate from the spirit and scope of the technical solution of the present utility model.
