Description

Technical Field

[0001] This utility model relates to the field of water channel board technology, specifically a water channel board structure. Background Technology

[0002] As people's pursuit of healthy and convenient drinking water continues to increase, drinking water equipment has gradually become an indispensable household appliance in people's daily lives. In drinking water equipment, the water circuit board, as one of the core components, plays a crucial role. The water circuit board is not only responsible for introducing water into the equipment, but also, through precise pipe design, realizes multiple functions such as water filtration, heating, cooling, and distribution.

[0003] Existing water circuit boards typically adopt a design that integrates water circuits on the same plane to meet basic water circuit connectivity requirements. However, the single-layer layout of water circuits makes the overall structure of the water circuit board less compact. When more water circuits need to be integrated or complex flow channel intersections are required, the water circuit board area can only be increased to accommodate the new flow channels, which significantly increases the overall volume of the water circuit board and is not conducive to saving space.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] Regarding the aforementioned issue of existing water circuit boards that integrate water circuits on a single plane, the single-layer layout of the water circuits results in an insufficiently compact overall structure. When more water circuits need to be integrated, the area of ​​the water circuit board must be increased, leading to a larger overall volume and hindering space conservation. The technical solution adopted by this utility model to solve this problem is as follows:

[0006] A water circuit board structure includes a water circuit board assembly. The water circuit board assembly includes a first water circuit board, which is divided into a first plane and a second plane according to the plane containing the central axis of the water pipe.

A first one-way valve is provided at the connection of the first water inlet pipe, the return pipe and the mineralized water inlet pipe, so that the pure water in the first water inlet pipe flows to the return pipe or the mineralized water inlet pipe.

[0009] Furthermore, the central axis of both the first water inlet pipe and the central axis of the mineralized water inlet pipe are located in the second plane.

[0010] Furthermore, the return pipeline includes a first return pipeline communicating with the first inlet pipeline and a second return pipeline communicating with the pre-filter outlet pipeline. The first water circuit board is provided with an activated carbon inlet pipeline communicating with the inlet end of the activated carbon filter installation position. A second one-way valve is provided between the activated carbon inlet pipeline and the first return pipeline so that pure water in the first return pipeline can flow to the activated carbon inlet pipeline. A return valve is provided between the first return pipeline and the second return pipeline so that pure water in the first return pipeline can flow to the second return pipeline. A return one-way valve is provided between the second return pipeline and the pre-filter outlet pipeline.

[0011] Furthermore, the first return pipeline includes a first return branch, the second check valve is located between the first return branch and the activated carbon inlet pipeline, and the central axis of the activated carbon inlet pipeline is located in the second plane.

[0012] Furthermore, the first water circuit board is provided with a first activated carbon outlet pipe connected to the pure water outlet pipe and a second activated carbon outlet pipe connected to the mineralized water inlet pipe. Both the first activated carbon outlet pipe and the second activated carbon outlet pipe are connected to the water outlet end of the activated carbon filter element installation position. The second activated carbon outlet pipe is provided with a third one-way valve.

[0013] Furthermore, a first TDS probe and a first high-voltage switch are provided between the first activated carbon outlet pipe and the pure water outlet pipe, and the central axis of the first activated carbon outlet pipe is located in the first plane.

[0014] Furthermore, the mineralized water outlet pipeline is equipped with a second TDS probe and a second high-voltage switch.

[0015] Furthermore, an inlet solenoid valve is provided on the side of the pre-filter outlet pipe away from the first outlet, and a booster pump is provided between the first outlet and the reverse osmosis filter inlet.

[0016] The beneficial effects of this utility model are as follows:

The central axes of the pure water outlet pipe and the mineralized water outlet pipe on the first water circuit board are both located on the first plane, while the central axis of the return pipe is located on the second plane. Compared to the traditional single-layer layout, this double-layer planar integrated water circuit design allows the first water circuit board to accommodate more water channels within a limited space, resulting in a more compact overall structure. This effectively solves the problem that existing water circuit boards, which use a single-plane integrated water circuit design, suffer from insufficient compactness. When more water channels need to be integrated, the area of ​​the water circuit board must be increased, leading to a larger overall volume and hindering space conservation.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 8 The diagram shows a water circuit board structure, including a water circuit board assembly. The water circuit board assembly includes a first water circuit board 1. The first water circuit board 1 is divided into a first plane and a second plane according to the plane where the central axis of the water pipe is located. The first plane and the second plane are arranged in parallel. The first water circuit board 1 is provided with a raw water inlet 11, a pre-filter installation position 2, a pre-filter outlet pipe 21 communicating with the pre-filter installation position 2, a return pipe 3 connected to the pre-filter outlet pipe 21, an activated carbon filter installation position 4, a pure water outlet pipe 5 communicating with the activated carbon filter installation position 4, a mineralized material filter installation position 6, and a mineralized water outlet pipe 61 communicating with the mineralized material filter installation position 6. The central axis of the pure water outlet pipe 5 and the central axis of the mineralized water outlet pipe 61 are both located in the first plane, and the central axis of the return pipe 3 is located in the second plane.

[0029] This invention features a first plane and a second plane arranged parallel to each other on a first water circuit board. The central axes of the pure water outlet pipe and the mineralized water outlet pipe on the first water circuit board are both located on the first plane, while the central axis of the return pipe is located on the second plane. Compared to the traditional single-layer layout, this double-layer planar integrated water circuit design allows the first water circuit board to accommodate more water channels within a limited space, resulting in a more compact overall structure. This effectively solves the problem that existing water circuit boards, which use a single-plane integrated water circuit design, suffer from insufficient compactness. When more water channels need to be integrated, the area of ​​the water circuit board must be increased, leading to a larger overall volume and hindering space conservation.

[0030] Furthermore, by arranging the pure water outlet pipe 5 and the mineralized water outlet pipe 61 on the first plane, and arranging the return pipe 3 on the second plane, it is beneficial to clarify the functional zoning. This not only facilitates the management and maintenance of the water system, but also reduces mutual interference between different functional pipes, which helps to improve the stability and reliability of the water system.

[0031] Furthermore, the pre-filter installed in pre-filter installation position 2 can perform preliminary filtration of raw water. The pre-filter can effectively intercept larger particulate impurities in the water, such as silt, rust, and suspended solids, which helps prevent these large particles from causing wear and blockage to subsequent filter elements and equipment, and effectively extends the service life of other filter elements.

[0032] Furthermore, the activated carbon filter installed in the activated carbon filter cartridge installation position 4 has a strong adsorption capacity. The activated carbon filter cartridge can remove residual chlorine, discoloration, odor, and some organic pollutants from the water. Under the action of the activated carbon filter cartridge, the taste and purity of the pure water can be further improved.

[0033] Furthermore, the mineral filter cartridge installed at the mineralization cartridge installation position 6 can add minerals beneficial to the human body, such as calcium, magnesium, and zinc, to the water. These minerals not only improve the taste of the water, making it sweeter, but also supplement the trace elements needed by the human body to a certain extent, meeting people's needs for healthy drinking water.

[0034] Specifically, the pre-filter installation position 2 includes a pre-filter inlet connected to the raw water inlet 11 and a pre-filter outlet connected to the pre-filter outlet pipe 21; the activated carbon filter installation position 4 includes an activated carbon inlet connected to the activated carbon inlet pipe 41 and an activated carbon outlet connected to the first activated carbon outlet pipe 42 and the second activated carbon outlet pipe 43 respectively; the mineralized material filter installation position 6 includes a mineralized material filter inlet connected to the mineralized inlet pipe 62 and a mineralized outlet connected to the mineralized outlet pipe 61.

[0035] Specifically, the first plane is a cross-section cut along line CC, and the second plane is a cross-section cut along line BB. Furthermore, through the return pipe 3, the pure water output from the reverse osmosis filter can be re-processed through the pre-filter outlet pipe 21 and then treated again by the reverse osmosis filter, which helps to further improve the stability of water quality and ensure that the output water quality always meets the standards. Secondly, the setting of the return pipe 3 can reduce the accumulation of impurities in the system. Through circulation treatment, some impurities are carried back to the reverse osmosis filter for filtration, thereby improving the filtration efficiency of the entire system.

[0036] like Figures 1 to 8 The first water circuit board 1 shown is provided with a first water outlet 12 connected to the pre-filter water outlet pipe 21 and a first water inlet 13. The water circuit board assembly includes a second water circuit board 7 detachably connected to the first water circuit board 1. The second water circuit board 7 is provided with a reverse osmosis filter installation position 71, a reverse osmosis filter inlet 72 connected to the first water outlet 12, a reverse osmosis filter outlet 73 connected to the first water inlet 13, and a wastewater outlet 74.

[0037] Furthermore, the first water circuit board 1 and the second water circuit board 7 are detachably connected, allowing users to flexibly choose whether to install the second water circuit board 7 according to their actual needs. When the water quality is good, users do not need reverse osmosis filtration and can use only the first water circuit board 1. When the water quality is poor, users can install the second water circuit board 7 to achieve a more advanced filtration function.

[0038] Furthermore, the modular design makes equipment upgrades and maintenance more convenient. Users can replace or upgrade the second water circuit board 7 individually without replacing the entire water circuit system, which not only reduces maintenance costs but also extends the service life of the equipment.

[0039] Furthermore, the pre-filter in the first water circuit plate 1 can perform preliminary filtration of the raw water, intercepting large particulate impurities. After the water flows out from the first outlet 12, it enters the reverse osmosis filter installation position 71 of the second water circuit plate 7. The reverse osmosis filter is a high-precision filtration device that can remove bacteria, viruses, heavy metal ions, dissolved salts and other tiny impurities and harmful substances from the water, effectively reducing the hardness of the water and making the water quality reach a higher purity standard.

[0040] Specifically, the reverse osmosis filter element mounting position 71 includes a first mounting port for water intake and connected to the reverse osmosis filter element inlet 72, a second mounting port for pure water output and connected to the reverse osmosis filter element outlet 73, and a third mounting port for concentrated water discharge and connected to the wastewater outlet 74.

[0041] like Figures 1 to 8 The first water circuit board 1 shown is provided with a first water inlet pipe 14 connected to the first water inlet 13 and communicating with the return pipe 3, and a mineralized water inlet pipe 62 communicating with the water inlet end of the mineralized material filter element installation position 6. A first one-way valve 91 is provided at the connection of the first water inlet pipe 14, the return pipe 3 and the mineralized water inlet pipe 62, so that the pure water in the first water inlet pipe 14 flows to the return pipe 3 or the mineralized water inlet pipe 62.

[0042] Specifically, the pure water filtered by the reverse osmosis filter element is transmitted to the first inlet water pipe 14 through the outlet 73 of the reverse osmosis filter element. The first inlet water pipe 14 is connected to the return water pipe 3. A first one-way valve 91 is provided at the connection between the first inlet water pipe 14 and the return water pipe 3 so that the pure water in the first inlet water pipe 14 can flow to the mineralized inlet water pipe 62 through the first one-way valve 91.

[0043] Optionally, in some embodiments, the first one-way valve 91 is opened so that pure water in the first inlet line 14 can flow to the mineralized inlet line 62.

[0044] Optionally, in some embodiments, the first one-way valve 91 is closed so that pure water in the first inlet pipe 14 can flow to the return pipe 3.

[0045] Furthermore, the first one-way valve 91 plays a role in strictly controlling the direction of water flow. The first one-way valve 91 can ensure that the pure water in the first water inlet pipe 14 can only flow in the preset direction, avoiding the backflow phenomenon, so that the water flow of the entire water system is more orderly.

[0046] Furthermore, by setting the first one-way valve 91, the user can distribute the pure water filtered by the reverse osmosis filter to different pipelines according to actual needs. When mineralization treatment is required, the pure water can flow to the mineralization filter through the mineralization inlet pipeline 62; when mineralization treatment is not required, the pure water can flow back to the pre-filter outlet pipeline 21 through the return pipeline 3.

[0047] like Figures 1 to 8 The central axis of the first water inlet pipe 14 and the central axis of the mineralized water inlet pipe 62 shown are both located in the second plane;

[0048] Furthermore, arranging the first water inlet pipe 14 and the mineralized water inlet pipe 62 on the second plane, while arranging the pure water outlet pipe 5 and the mineralized water outlet pipe 61 on the first plane, facilitates the implementation of a layered design and helps reduce the overall volume of the water circuit board, making the overall structure of the water circuit board more compact.

[0049] Furthermore, arranging pipelines with different functions on different planes can reduce mutual interference between pipelines with different functions, which is beneficial to improving the stability and reliability of the water system.

[0050] Furthermore, the first water inlet pipe 14 and the mineralized water inlet pipe 62 are arranged on the second plane to make the structure of the entire water circuit board clearer, making it easier for users to install and maintain. Users can more intuitively find the location of each pipe and perform installation, replacement or repair operations.

[0051] like Figures 1 to 8 The reflux pipeline 3 shown includes a first reflux pipeline 31 connected to the first inlet pipeline 14 and a second reflux pipeline 32 connected to the pre-filter outlet pipeline 21. The first water circuit plate 1 is provided with an activated carbon inlet pipeline 41 connected to the inlet end of the activated carbon filter installation position 4. A second one-way valve 92 is provided between the activated carbon inlet pipeline 41 and the first reflux pipeline 31 so that pure water in the first reflux pipeline 31 can flow to the activated carbon inlet pipeline 41. A reflux valve 93 is provided between the first reflux pipeline 31 and the second reflux pipeline 32 so that pure water in the first reflux pipeline 31 can flow to the second reflux pipeline 32. A reflux one-way valve 94 is provided between the second reflux pipeline 32 and the pre-filter outlet pipeline 21.

[0052] Specifically, when the reflux valve 93 is open, the pure water in the first reflux pipe 31 can enter the second reflux pipe 32; when the reflux check valve 94 is open, the pure water in the second reflux pipe 32 can enter the pre-filter outlet pipe 21; when the second check valve 92 is open, the pure water in the first reflux pipe 31 can enter the activated carbon inlet pipe 41.

[0053] Furthermore, by setting up the return pipeline 3, the pure water filtered by the reverse osmosis filter can be distributed to different pipelines as needed. When the activated carbon filter needs to be replenished with water, the pure water can flow to the activated carbon inlet pipeline 41 through the first return pipeline 31 and the second one-way valve 92. When the pure water needs to be returned to the pre-filter outlet pipeline 21, the pure water can flow to the pre-filter outlet pipeline 21 through the second return pipeline 32 and the return one-way valve 94, so that the pure water can be flexibly distributed within the system, which is conducive to improving the utilization efficiency of water resources.

[0054] Furthermore, the second check valve 92, the return valve 93, and the return check valve 94 ensure unidirectional water flow and reduce the risk of water quality degradation caused by water backflow.

[0055] like Figures 1 to 8 The first return pipeline 31 shown includes a first return branch 311, and the second one-way valve 92 is located between the first return branch 311 and the activated carbon inlet pipeline 41. The central axis of the activated carbon inlet pipeline 41 is located in the second plane.

[0056] Furthermore, the central axis of the activated carbon inlet pipe 41 is located in the second plane, and the central axis of the first return branch 311 is also located in the second plane. This facilitates the connection and coordinated operation of the activated carbon inlet pipe 41 with the first return branch 311, and helps to reduce the complexity and difficulty in the connection process.

[0057] Furthermore, by setting the central axis of the activated carbon inlet pipe 41 on the second plane, it is beneficial to centrally arrange and integrate the related pipes. Together with other pipes also located on the second plane, the structure of the entire water system can be made more compact.

[0058] Furthermore, a stable water flow direction and a reasonable pipeline layout help ensure the water treatment effect of the activated carbon filter element. The water entering the activated carbon inlet pipe 41 can pass through the activated carbon filter element evenly and stably, allowing the activated carbon to fully exert its function of adsorbing residual chlorine, discoloration, odor and some organic matter, avoiding insufficient activated carbon treatment caused by unstable water flow or backflow, thereby ensuring the taste and quality of the output water.

[0059] like Figures 1 to 8 The first water circuit board 1 shown is provided with a first activated carbon outlet pipe 42 connected to the pure water outlet pipe 5 and a second activated carbon outlet pipe 43 connected to the mineralized water inlet pipe 62. The first activated carbon outlet pipe 42 and the second activated carbon outlet pipe 43 are both connected to the outlet end of the activated carbon filter element installation position 4. The second activated carbon outlet pipe 43 is provided with a third one-way valve 95.

[0060] Furthermore, by setting up the first activated carbon outlet pipe 42 and the second activated carbon outlet pipe 43, users can distribute the water treated by the activated carbon filter to different pipes according to their actual needs. For example, when it is necessary to use the water treated by the activated carbon directly, the water can flow through the first activated carbon outlet pipe 42 to the pure water outlet pipe 5; when it is necessary to further mineralize the water treated by the activated carbon, the water can flow through the second activated carbon outlet pipe 43 to the mineralization inlet pipe 62.

[0061] Furthermore, by installing a third one-way valve 95 on the second activated carbon outlet pipe 43, reverse flow of water can be effectively prevented, which helps ensure that the water treated by activated carbon flows to the mineralization inlet pipe 62 and does not flow back to the activated carbon filter element installation position 4, thus helping to avoid water pollution.

[0062] Furthermore, by reasonably setting the third check valve 95, the pressure fluctuation of the water flow in the system can be effectively reduced. When the water flow is distributed and switched, the third check valve 95 can ensure that the water flow is smoothly directed to the mineralized water inlet pipe 62, avoiding system instability caused by water flow impact or pressure changes.

[0063] like Figures 1 to 8 A first TDS probe 96 and a first high-voltage switch 97 are provided between the first activated carbon outlet pipe 42 and the pure water outlet pipe 5 shown. The central axis of the first activated carbon outlet pipe 42 is located in the first plane.

[0064] Furthermore, the first TDS probe 96 is set to detect the TDS value (total dissolved solids) of the water flowing from the first activated carbon outlet pipe 42 into the pure water outlet pipe 5 in real time. The TDS value reflects the total amount of various solid substances dissolved in the water and is an important indicator for measuring the purity of water. By monitoring the TDS value in real time, users can understand the water quality after being filtered by activated carbon.

[0065] Furthermore, the first high-pressure switch 97 can control the start and stop of the equipment according to the water pressure in the pipeline. When the water pressure in the pure water outlet pipeline 5 reaches the set upper limit, the first high-pressure switch 97 will automatically cut off the power supply of the equipment and stop the water production process to prevent damage to the equipment due to excessive water pressure.

[0066] Furthermore, by setting the central axis of the first activated carbon outlet pipe 42 on the first plane, the first activated carbon outlet pipe 42 can be reasonably laid out and arranged with other pipes and components, avoiding the entanglement and crossing between pipes, reducing the complexity and disorder of the pipe layout, and making the water circuit board more compact.

[0067] like Figures 1 to 8The mineralized water outlet pipeline 61 shown is equipped with a second TDS probe 98 and a second high-voltage switch 99;

[0068] Furthermore, by installing a second TDS probe 98 on the mineralized water outlet pipe 61, users can monitor the water quality after mineralization treatment in real time. The second TDS probe 98 can detect the total amount of dissolved solids in the water, thereby ensuring that the water quality meets the purity and mineral content required by the user.

[0069] Furthermore, by installing a second high-pressure switch 99 on the mineralized water outlet pipeline 61, the user can monitor the pressure in the water circuit to ensure that the system operates within a safe pressure range. When the water pressure is too high, the second high-pressure switch 99 can automatically cut off the power supply or trigger an alarm to prevent the system from being damaged due to excessive pressure, which is beneficial to improving the safety and reliability of the system.

[0070] like Figures 1 to 8 The pre-filter cartridge water outlet pipe 21 shown is provided with an inlet solenoid valve 15 on the side away from the first water outlet 12, and a booster pump is provided between the first water outlet 12 and the reverse osmosis filter cartridge inlet 72.

[0071] Furthermore, the inlet solenoid valve 15 can effectively prevent water backflow, especially when the system is shut down, which helps to avoid water pollution or equipment damage caused by water backflow.

[0072] Furthermore, the booster pump can increase the pressure of the water flow, ensuring that the water can pass through the reverse osmosis filter with sufficient pressure, thereby improving the filtration efficiency. The reverse osmosis filter requires high pressure to effectively remove impurities and dissolved solids from the water, and the booster pump ensures that the system operates at high efficiency.

[0073] Furthermore, by installing an inlet solenoid valve 15 on the pre-filter outlet pipe 21 and a booster pump between the first outlet 12 and the reverse osmosis filter inlet 72, the water flow path is clearer, making it easier for users to understand the system's operating status.

[0074] The operating mode of this water circuit board assembly is as follows:

[0075] External tap water enters the first water circuit board 1 through the raw water inlet 11. The inlet of the pre-filter cartridge is connected to the raw water inlet 11 so that the tap water can enter the pre-filter cartridge for preliminary filtration. The filtered tap water flows through the outlet of the pre-filter cartridge to the outlet pipe 21 of the pre-filter cartridge. The first outlet 12 is connected to the inlet 72 of the reverse osmosis cartridge so that the tap water in the outlet pipe 21 of the pre-filter cartridge can flow to the installation position 71 of the reverse osmosis cartridge and enter the reverse osmosis cartridge for filtration through the first installation port. Under the action of the reverse osmosis cartridge, the generated concentrated water is discharged to the outside through the wastewater outlet 74, and the generated pure water enters the first inlet pipe 14 through the outlet 73 of the reverse osmosis cartridge and the first inlet 13 in sequence.

[0076] When the first mineralized water needs to be output, the first one-way valve 91 opens so that the pure water in the first water inlet pipe 14 can enter the mineralized water inlet pipe 62 and enter the mineralized material filter element through the water inlet of the mineralized material filter element for mineralization. The mineralized water enters the mineralized water outlet pipe 61 through the water outlet of the mineralized material filter element and is discharged to the outside for user use.

[0077] The first water inlet pipe 14 is connected to the first return pipe 31, and the pure water in the first water inlet pipe 14 enters the first return pipe 31;

[0078] When pure water needs to be output, the pure water in the first return pipe 31 enters the first return branch 311, and the second one-way valve 92 opens so that the pure water in the first return branch 311 can enter the activated carbon inlet pipe 41. The activated carbon inlet pipe 41 is connected to the inlet of the activated carbon filter element. The pure water enters the activated carbon filter element for further filtration, thereby improving the taste of drinking water. The filtered pure water enters the first activated carbon outlet pipe 42 through the outlet of the activated carbon filter element. The first activated carbon outlet pipe 42 is connected to the pure water outlet pipe 5 so that the pure water can be discharged to the outside for user use through the pure water outlet pipe 5.

[0079] When the second mineralized water needs to be output, the pure water in the first return pipe 31 enters the first return branch 311, and the second one-way valve 92 opens so that the pure water in the first return branch 311 can enter the activated carbon inlet pipe 41. The activated carbon inlet pipe 41 is connected to the inlet of the activated carbon filter element. The pure water enters the activated carbon filter element for further filtration, thereby improving the taste of drinking water. The filtered pure water enters the second activated carbon outlet pipe 43 through the outlet of the activated carbon filter element. At this time, the third one-way valve 95 opens so that the pure water in the second activated carbon outlet pipe 43 can enter the mineralization inlet pipe 62 and enter the mineralization filter element through the inlet of the mineralization filter element for mineralization. The mineralized water enters the mineralization outlet pipe 61 through the outlet of the mineralization filter element and is discharged to the outside for user use.

[0080] When recirculation is required for repeated filtration, the recirculation valve 93 opens, allowing the pure water in the first recirculation pipe 31 to enter the second recirculation pipe 32. The recirculation check valve 94 also opens, allowing the pure water in the second recirculation pipe 32 to re-enter the pre-filter outlet pipe 21 under the action of the recirculation check valve 94. The first outlet 12 is connected to the reverse osmosis filter inlet 72, so that the pure water in the pre-filter outlet pipe 21 can flow back to the reverse osmosis filter in the second water circuit plate 7 for further filtration.

[0081] The implementation method of Example 1 is as follows:

[0082] A water circuit board structure includes a water circuit board assembly, which includes a first water circuit board 1. The first water circuit board 1 is divided into a first plane and a second plane according to the plane where the central axis of the water pipe is located. The first plane and the second plane are arranged in parallel. The first water circuit board 1 is provided with a raw water inlet 11, a pre-filter installation position 2, a pre-filter outlet pipe 21 communicating with the pre-filter installation position 2, a return pipe 3 connected to the pre-filter outlet pipe 21, an activated carbon filter installation position 4, a pure water outlet pipe 5 communicating with the activated carbon filter installation position 4, a mineralized material filter installation position 6, and a mineralized water outlet pipe 61 communicating with the mineralized material filter installation position 6. The central axis of the pure water outlet pipe 5 and the central axis of the mineralized water outlet pipe 61 are both located in the first plane, and the central axis of the return pipe 3 is located in the second plane.

[0083] This invention features a first plane and a second plane arranged parallel to each other on a first water circuit board. The central axes of the pure water outlet pipe and the mineralized water outlet pipe on the first water circuit board are both located on the first plane, while the central axis of the return pipe is located on the second plane. Compared to the traditional single-layer layout, this double-layer planar integrated water circuit design allows the first water circuit board to accommodate more water channels within a limited space, resulting in a more compact overall structure. This effectively solves the problem that existing water circuit boards, which use a single-plane integrated water circuit design, suffer from insufficient compactness. When more water channels need to be integrated, the area of ​​the water circuit board must be increased, leading to a larger overall volume and hindering space conservation.
