[0067] Reference is made below Figures 1 - 13 to describe the integrated waterway board 100 according to an embodiment of the present utility model.

[0068] In combination with Figure 1 and Figure 2 as well as Figure 7 and Figure 8 , the integrated waterway board 100 according to an embodiment of the present utility model includes a waterway board body 1. The waterway board body 1 has an inlet water flow channel 11, an intermediate flow channel 12, a first outlet water flow channel 13 in a normally open state, a second outlet water flow channel 14, a third outlet water flow channel 15, a water inlet 16 for connecting to a water source, a first water outlet 17 for connecting to a drinking water device, a second water outlet 18 for connecting to a drinking water switch, and a third water outlet 19 for connecting to a preset switch.

[0069] The water inlet 16, multiple flow channels, and multiple water outlets together form a waterway system. The waterway system is formed on the integrated waterway board 100, which is beneficial to realizing the modular design of the waterway system, and can make the structure of the integrated waterway board 100 compact, which is beneficial to saving the mold opening cost, reducing the production cost of the integrated waterway board 100, and is beneficial to improving the assembly efficiency of the integrated waterway board 100.

[0070] In combination with Figure 1 and Figure 2 as well as Figure 7 and Figure 8 , one end of the inlet water flow channel 11 is communicated with the water inlet 16 and the other end is communicated with one end of the intermediate flow channel 12. One end of the first outlet water flow channel 13 is communicated with the other end of the intermediate flow channel 12 and the other end is communicated with the first water outlet 17. One end of the second outlet water flow channel 14 is communicated with the other end of the intermediate flow channel 12 and the other end is communicated with the second water outlet 18. One end of the third outlet water flow channel 15 is communicated with the middle part of the intermediate flow channel 12 and the other end is communicated with the third water outlet 19.

[0071] Water from the water source flows into the inlet channel 11 through the water inlet 16, and further flows from the inlet channel 11 into the intermediate channel 12. The intermediate channel 12 is respectively connected to the first outlet channel 13, the second outlet channel 14, and the third outlet channel 15. The water in the intermediate channel 12 can flow into the first outlet channel 13, the second outlet channel 14, and the third outlet channel 15 respectively.

[0072] Among them, the first outlet channel 13 is connected to the drinking water equipment through the first water outlet 17, that is, the water in the first outlet channel 13 can flow into the drinking water equipment, and the drinking water equipment can heat or cool the water to meet the user's usage requirements; the second outlet channel 14 is connected to the drinking water switch through the second water outlet 18, that is, the water in the second outlet channel 14 can flow to the drinking water switch and be discharged through the drinking water switch, and the water discharged through the drinking water switch can be directly drunk; the third outlet channel 15 is connected to a preset switch through the third water outlet 19. For example, the third outlet channel 15 can flow out corresponding functional water according to the preset function. For example, the functional water can be bubble water or domestic water with a lower purity, etc., and the preset switch can be a bubble water switch or a domestic water switch, etc.

[0073] Thus, various water channel functions of the integrated water circuit board 100 are realized, so that the water discharged from the integrated water circuit board 100 can have different functions, which is beneficial to improving the functionality of the equipment using the integrated water circuit board 100, and thus beneficial to improving the user's usage experience.

[0074] According to the integrated water circuit board 100 of the embodiment of the present invention, by providing the inlet channel 11, the intermediate channel 12, the first outlet channel 13, the second outlet channel 14, the third outlet channel 15, the water inlet 16, the first water outlet 17, the second water outlet 18, and the third water outlet 19 on the water circuit board body 1, the modular design of the water circuit system is realized, which is beneficial to improving the structural compactness of the integrated water circuit board 100, simplifying the water circuit system, facilitating connection and maintenance, reducing the hidden danger of water leakage, and also reducing the production cost of the integrated water circuit board 100.

[0075] In addition, the integrated water circuit board 100 has various water channel functions, so that the water discharged from the integrated water circuit board 100 can have different functions, which is beneficial to improving the functionality of the water purification equipment, and the third water outlet 19 can be connected to different preset switches, so that the integrated water circuit board 100 can be adapted to water purification equipment with different functions.

[0076] Combined Figure 1 and Figure 2 、 Figure 4 and Figure 5 、 Figure 7 and Figure 8 and Figure 10 and Figure 11, in some embodiments of the present utility model, the waterway board body 1 further has a first filter element water inlet interface 110 and a first filter element water outlet interface 111 for connecting the first filter element 2, and both the first filter element water inlet interface 110 and the first filter element water outlet interface 111 are communicated with the intermediate flow channel 12.

[0077] After water flows into the intermediate flow channel 12 through the water inlet 16 and the water inlet flow channel 11, the water can flow into the first filter element 2 through the first filter element water inlet interface 110. The first filter element 2 can filter the water flowing through it to remove harmful substances in the water and improve the water quality. The water filtered by the first filter element 2 flows to the intermediate flow channel 12 through the first filter element water outlet interface 111.

[0078] Combined Figure 1 and Figure 2 、 Figure 4 and Figure 5 、 Figure 7 and Figure 8 as well as Figure 10 and Figure 11 , wherein, the waterway board body 1 further has a pump water inlet interface 112 and a pump water outlet interface 113 for connecting the booster pump 3, and both the pump water inlet interface 112 and the pump water outlet interface 113 are communicated with the intermediate flow channel 12. In the water flow direction in the intermediate flow channel 12, the pump water outlet interface 113 is located upstream of the first filter element water inlet interface 110.

[0079] During the process of water flowing from the water inlet flow channel 11 to the first filter element 2, the water preferentially flows into the booster pump 3 through the pump water inlet interface 112. The booster pump 3 can pressurize the water. The pressurized water flows into the intermediate flow channel 12 through the pump water outlet interface 113 and further flows into the first filter element 2. By setting the booster pump 3, it can prevent the normal operation of the first filter element 2 from being affected due to insufficient water pressure, which is beneficial to improving the water filtration effect of the first filter element 2.

[0080] Combined Figure 4 and Figure 5 as well as Figure 10 and Figure 11 , in some embodiments of the present utility model, the second water outlet flow channel 14 is in a normally open state, and the drinking water switch connected to the second water outlet 18 has an opening and closing function. When the user needs to receive drinking water, the user can open the drinking water switch so that the water in the second water outlet flow channel 14 can flow out. When the user does not need to receive drinking water, the user can close the drinking water switch, thereby closing the second water outlet 18 to prevent the drinking water from flowing out of the second water outlet flow channel 14. Thus, there is no need to set up structures such as opening and closing valves on the integrated waterway board 100, effectively simplifying the structure of the integrated waterway board 100, which is beneficial to reducing the production cost of the integrated waterway board 100 and facilitating the production and assembly of the integrated waterway board 100.

[0081] Or, combined Figure 1and Figure 2 and Figure 7 and Figure 8 The waterway board body 1 further has a first water outlet valve water inlet interface 114 and a first water outlet valve water outlet interface 115 for connecting the first water outlet valve 4. Both the first water outlet valve water inlet interface 114 and the first water outlet valve water outlet interface 115 are communicated with the second water outlet flow channel 14, so that the first water outlet valve 4 controls the on-off of the second water outlet flow channel 14.

[0082] During the process of the water in the second water outlet flow channel 14 flowing towards the second water outlet 18, it preferentially flows through the first water outlet valve water inlet interface 114 towards the first water outlet valve 4. When the first water outlet valve 4 is opened, the water in the second water outlet flow channel 14 can flow through the first water outlet valve 4 through the first water outlet valve water inlet interface 114 and the first water outlet valve water outlet interface 115, and further flow towards the second water outlet 18, and the user can receive drinking water; when the first water outlet valve 4 is closed, the water in the second water outlet flow channel 14 cannot flow towards the second water outlet 18 to prevent the drinking water from flowing out of the second water outlet flow channel 14. Thus, by arranging the first water outlet valve 4 on the integrated waterway board 100 to control the on-off of the second water outlet flow channel 14, it is beneficial to improve the integration degree of the integrated waterway board 100.

[0083] Combined with Figures 1 - 6 In some embodiments of the present utility model, one end of the third water outlet flow channel 15 is communicated between the pump water outlet interface 113 and the first filter element water inlet interface 110. The waterway board body 1 further has a first control valve water inlet interface 116 and a first control valve water outlet interface 117 for connecting the first control valve 5. Both the first control valve water inlet interface 116 and the first control valve water outlet interface 117 are located between the communication position of the third water outlet flow channel 15 and the intermediate flow channel 12 and the first filter element water inlet interface 110, so that the first control valve 5 controls the on-off of the water flow therebetween.

[0084] When the first control valve 5 is opened, the water flowing out of the self - pressurizing pump 3 can flow through the first control valve water inlet interface 116 towards the first control valve 5, and further flow through the first control valve water outlet interface 117 and the first filter element water inlet interface 110 into the first filter element 2. The first filter element 2 filters the water, and the filtered water flows out through the first filter element water outlet interface 111.

[0085] When the first control valve 5 is closed, the water flowing out of the self - pressurizing pump 3 cannot flow towards the first filter element 2, but flows into the third water outlet flow channel 15 from the pump water outlet interface 113 and flows out of the third water outlet flow channel 15 to output preset functional water to meet different usage requirements of users.

[0086] Combined with Figure 1 and Figure 2, the waterway board body 1 also has a second water outlet valve water inlet interface 118 and a second water outlet valve water outlet interface 119 for connecting the second water outlet valve 6. Both the second water outlet valve water inlet interface 118 and the second water outlet valve water outlet interface 119 are communicated with the third water flow channel 15, so that the second water outlet valve 6 controls the on-off of the third water flow channel 15.

[0087] When the second water outlet valve 6 is in the open state, the third water flow channel 15 is in a through path. The water flowing into the third water flow channel 15 can flow into the second water outlet valve 6 through the second water outlet valve water inlet interface 118 and further flow to the third water outlet 19 through the second water outlet valve water outlet interface 119. At this time, the third water flow channel 15 can discharge the preset functional water. When the user does not need to receive the preset functional water, the second water outlet valve 6 is in the closed state, thereby closing the third water flow channel 15.

[0088] Combined Figure 1 with Figure 2 , the integrated waterway board 100 also includes an air intake module 7 and a bubble module 8. The air intake module 7 is communicated with the intermediate flow channel 12 and is located upstream of the pump water inlet interface 112. The bubble module 8 is communicated with the flow channel between the pump water outlet interface 113 and the first filter element water inlet interface 110 on the intermediate flow channel 12, so that the third water flow channel 15 can produce bubble water.

[0089] As Figure 1 shown, the air intake module 7 includes a water inlet section 71, an air intake section 72, and a mixing and discharging section 73. Among them, one end of the water inlet section 71 is communicated with the intermediate flow channel 12. A third control valve 711 is provided on the water inlet section 71. The third control valve 711 can control the on-off of the water inlet section 71. When the third control valve 711 is opened, the water in the intermediate flow channel 12 can flow into the water inlet section 71. The other end of the water inlet section 71 is provided with a jet pump 713. The water flowing into the water inlet section 71 can flow to the jet pump 713.

[0090] Referring to Figure 1 , one end of the air intake section 72 is provided with an air suction port 721, and the other end of the air intake section 72 is connected to the jet pump 713. Air can be inhaled into the air intake section 72 through the air suction port 721, and a carbon cake 722 is provided at the air suction port 721. The carbon cake 722 can adsorb the peculiar smell of the air entering the air intake section 72, and then the air flows to the jet pump 713 and is initially mixed with water.

[0091] The jet pump 713 is also connected to one end of the mixing and discharging section 73. The other end of the mixing and discharging section 73 is connected to the intermediate flow channel 12 and is located upstream of the pump water inlet interface 112 and downstream of the connection between the water inlet section 71 and the intermediate flow channel 12. The initially mixed water and air further flow into the booster pump 3, and the booster pump 3 pressurizes it. The pressurized water and air flow into the bubble module 8.

[0092] Reference Figure 1 Among them, a pressure reducing valve 712 is arranged between the third control valve 711 and the injector 713. The pressure reducing valve 712 can reduce the pressure of the water flowing to the injector 713, thereby facilitating the reduction of the pressure in the air intake section 72, enabling air to smoothly enter the air intake section 72. A first check valve 724 is arranged on the air intake section 72. The first check valve 724 can ensure the flow direction of air and prevent air from flowing back or water from leaking through the air suction port 721.

[0093] Meanwhile, a solenoid valve 723 is arranged between the air suction port 721 and the first check valve 724. When the solenoid valve 723 is unloaded, along the direction extending from the injector 713 to the air suction port 721, the solenoid valve 723 is not conducting, and it can be equivalent to a check valve to ensure the flow direction of air and prevent air from flowing back or water from leaking through the air suction port 721 when the first check valve 724 fails.

[0094] The bubble module 8 is communicated with the intermediate flow channel 12, and the connection between the bubble module 8 and the intermediate flow channel 12 is located between the pump water outlet interface 113 and the first filter element water inlet interface 110. Meanwhile, the bubble module 8 is communicated with the third water outlet flow channel 15. The bubble module 8 includes a gas mixing tank 81 and a bubble generator 82. The pressurized water and air flow through the gas mixing tank 81 and the bubble generator 82 in sequence to form bubble water, so that bubble water can be prepared in the third water outlet flow channel 15, and the bubble water can be discharged through the third water outlet 19.

[0095] Combined with Figures 10 - 12 In some embodiments of the present invention, one end of the third water outlet flow channel 15 is communicated with the middle of the intermediate flow channel 12 and is located upstream of the pump water inlet interface 112. Among them, the preset switch is a domestic water switch and the third water outlet flow channel 15 is in a normally open state.

[0096] The water flowing out of the water inlet flow channel 11 flows into the intermediate flow channel 12, and then flows into the third water outlet flow channel 15 from the intermediate flow channel 12. At this time, the water has not passed through the first filter element 2 and its purity is relatively low, and it can be used as domestic water (i.e., for scrubbing or watering flowers, etc.). The third water outlet 19 is connected to the domestic water switch, and the domestic water switch has an opening and closing function. The user can open and close the domestic water switch according to their own usage needs, thereby controlling the on-off of the third water outlet flow channel 15.

[0097] By setting the domestic water switch with an opening and closing function, there is no need to set structures such as an opening and closing valve on the integrated water circuit board 100, effectively simplifying the structure of the integrated water circuit board 100 and facilitating the reduction of the production cost of the integrated water circuit board 100.

[0098] Or, combined with Figures 7 - 9, the preset switch is the domestic water switch. The waterway board body 1 also has a second water valve inlet interface 118 and a second water valve outlet interface 119 for connecting the second water valve 6. Both the second water valve inlet interface 118 and the second water valve outlet interface 119 are communicated with the third water flow channel 15, so that the second water valve 6 controls the on-off of the third water flow channel 15.

[0099] The water in the third water flow channel 15 preferentially flows through the second water valve 6 during the process of flowing towards the third water outlet 19. When the second water valve 6 is opened, the third water flow channel 15 can discharge domestic water. When the second water valve 6 is closed, the third water flow channel 15 is in an off state, and the third water flow channel 15 cannot discharge domestic water. At this time, the domestic water switch does not need to have an opening and closing function.

[0100] Thus, by setting the second water valve 6 on the integrated waterway board 100 to control the on-off of the third water flow channel 15, it is beneficial to improve the integration degree of the integrated waterway board 100.

[0101] Combined with Figures 1 - 3 , the waterway board body 1 also has a second filter element inlet interface 120 and a second filter element outlet interface 121 for connecting the second filter element 9. The second filter element inlet interface 120 is communicated with the other end of the water inlet flow channel 11. The first filter element outlet interface 111 is communicated with one end of the intermediate flow channel 12. In the water flow direction in the intermediate flow channel 12, the second filter element outlet interface 121 is located upstream of the first filter element inlet interface 110.

[0102] Water flows into the water inlet flow channel 11 through the water inlet 16 and then further flows into the second filter element 9. The second filter element 9 preliminarily filters the water. The water after preliminary filtration further flows into the intermediate flow channel 12, and then the water after preliminary filtration can flow into the first filter element 2 through the booster pump 3 and the first filter element inlet interface 110. The first filter element 2 can further filter the water to improve the water quality.

[0103] When it is not necessary to further filter the water through the first filter element 2, the first control valve 5 can be in a closed state. The water after preliminary filtration can flow into the third water flow channel 15, and the third water flow channel 15 can discharge the preset functional water (for example: bubble water or domestic water).

[0104] Combined with Figure 1 and Figure 2 , the waterway board body 1 also has an inlet valve inlet interface 122 and an inlet valve outlet interface 123 for connecting the inlet valve 10. In the water flow direction in the water inlet flow channel 11, the inlet valve outlet interface 123 is located upstream of the second filter element inlet interface 120, so that the inlet valve 10 controls the on-off of the water inlet flow channel 11.

[0105] When the inlet valve 10 is in the open state, the inlet water flow channel 11 is in a through path. Water enters the inlet water flow channel 11 through the water inlet 16, flows through the inlet valve 10, and further flows to the second filter element 9. After the second filter element 9 preliminarily filters the water, the water can selectively flow into the first water outlet flow channel 13, the second water outlet flow channel 14, and the third water outlet flow channel 15, and the user can draw water according to actual usage requirements; when the inlet valve 10 is in the closed state, the inlet valve 10 can cut off the water flowing into the inlet water flow channel 11, and the water purification device can be in the closed state.

[0106] Combined with Figures 1 - 6 , the waterway board body 1 also has a second control valve water inlet interface 124 and a second control valve water outlet interface 125 for connecting the second control valve 20. In the water flow direction in the intermediate flow channel 12, the second control valve water inlet interface 124 and the second control valve water outlet interface 125 are located between the second filter element water outlet interface 121 and the pump water inlet interface 112, so that the second control valve 20 controls the on-off of the water flow between the second filter element 9 and the booster pump 3.

[0107] The second control valve 20 is arranged on the intermediate flow channel 12, and the second control valve 20 is located between the connection position of the water inlet section 71 and the intermediate flow channel 12 and the connection position of the mixed discharge section 73 and the intermediate flow channel 12. When the user needs to draw sparkling water, the second control valve 20 is closed, and the third control valve 711 is opened. Water flows from the inlet water flow channel 11 into the intermediate flow channel 12, and flows from the intermediate flow channel 12 into the water inlet section 71. Air enters the suction section through the air suction port 721 and is mixed with water at the ejector 713. The mixed water flows through the mixed discharge section 73 to the booster pump 3 and further flows into the bubble module 8, and sparkling water can be produced in the third water outlet flow channel 15.

[0108] When the user does not need to draw sparkling water, the third control valve 711 is closed, and the second control valve 20 is opened. The water flows through the second filter element 9 and then into the intermediate flow channel 12 and further through the booster pump 3 to the first filter element 2. At this time, the water in the integrated waterway board 100 can flow into the drinking water device or flow out through the drinking water switch.

[0109] Combined with Figures 1 - 3 , in some embodiments of the present invention, the waterway board body 1 also has a third filter element water inlet interface 126 and a third filter element water outlet interface 127 for connecting the third filter element 30. Both the third filter element water inlet interface 126 and the third filter element water outlet interface 127 are communicated with the intermediate flow channel 12. In the water flow direction in the intermediate flow channel 12, the third filter element water inlet interface 126 is located downstream of the first filter element water outlet interface 111.

[0110] Water flows into the intermediate flow channel 12 and can further flow into the first filter element 2. After being filtered by the first filter element 2, the water can further flow into the third filter element 30. After the third filter element 30 further filters the water, the water flows into the intermediate flow channel 12 through the third filter element water outlet interface 127 and can selectively flow to the first water outlet 17 or the second water outlet 18.

[0111] Combined with Figure 1 and Figure 2 In some embodiments of the present utility model, the water circuit board body 1 further has a return water flow channel 128. One end of the return water flow channel 128 is communicated with the intermediate flow channel 12 and is located upstream of the pump water inlet interface 112, and the other end of the return water flow channel 128 is communicated with the intermediate flow channel 12 and is located downstream of the third filter element water outlet interface 127.

[0112] After the water enters the water inlet flow channel 11, it flows into the intermediate flow channel 12 and further into the first filter element 2. The first filter element 2 filters the water. The water with better purity after filtration flows into the intermediate flow channel 12 through the first filter element water outlet interface 111 and further flows into the third filter element 30 through the third filter element water inlet interface 126. The third filter element 30 further filters the water. The filtered water flows into the intermediate flow channel 12 through the third filter element water outlet interface 127 and flows into the return water flow channel 128 from the intermediate flow channel 12. The water flows through the return water flow channel 128 into the intermediate flow channel 12 and further flows into the booster pump 3 through the pump water inlet interface 112. The booster pump 3 pressurizes the water flowing through it, and then the water further flows into the first filter element 2 to wash the first filter element 2, preventing impurities from accumulating in the first filter element 2 and blocking the first filter element 2. The waste water generated after washing the first filter element 2 is discharged from the integrated water circuit board 100.

[0113] Combined with Figure 1 and Figure 2 The water circuit board body 1 further has a return water inlet interface 129 and a return water outlet interface 130 for connecting the return water valve 40. Both the return water inlet interface 129 and the return water outlet interface 130 are communicated with the return water flow channel 128 to enable the return water valve 40 to control the on-off of the return water flow channel 128.

[0114] When the return water valve 40 is opened, the return water flow channel 128 is in a through state. The water flowing out of the third filter element 30 can flow into the return water flow channel 128 and further flow into the first filter element 2 to wash the first filter element 2. When it is not necessary to wash the first filter element 2 and the return water valve 40 is closed, the return water flow channel 128 is in a disconnected state, and at this time, the water cannot flow into the first filter element 2 through the return water flow channel 128.

[0115] Combined with Figure 1 and Figure 2, in some embodiments of the present utility model, a second one-way valve 60 is provided on the return water flow channel 128. In the flowing direction of the water in the return water flow channel 128, the second one-way valve 60 is located downstream of the return water outlet interface 130. The second one-way valve 60 can ensure the one-way flow of water in the return water flow channel 128 and prevent water from flowing into other flow channels through the return water flow channel 128 during the process of the water flowing from the second filter element 9 through the first filter element 2.

[0116] In some embodiments of the present utility model, the two ends of the water circuit board body 1 in the first direction are respectively a first end and a second end. The water inlet flow channel 11 and the third water outlet flow channel 15 both extend from the first end to the second end in the first direction and are arranged in the second direction. The first water outlet flow channel 13, the second water outlet flow channel 14 and at least a part of the intermediate flow channel 12 are located between the water inlet flow channel 11 and the third water outlet flow channel 15.

[0117] It should be noted that the "first direction" can be the length direction of the water circuit board body 1, the "second direction" can be the width direction of the water circuit board body 1, or the "first direction" can be the width direction of the water circuit board body 1, the "second direction" can be the length direction of the water circuit board body 1, and the first direction and the second direction are respectively perpendicular to the thickness direction of the water circuit board body 1. The specific direction illustration can be referred to Figure 2 as shown.

[0118] As Figure 2 shown, the water inlet flow channel 11 and the third water outlet flow channel 15 respectively extend from the first end of the water circuit board body 1 to the second end along the first direction, so that there is enough layout space for the water inlet flow channel 11 and the third water outlet flow channel 15 on the water circuit board. At the same time, the water inlet flow channel 11 and the third water outlet flow channel 15 are arranged at intervals in the second direction, which is convenient for arranging at least part of the first water outlet flow channel 13 and the second water outlet flow channel 14 between the water inlet flow channel 11 and the third water outlet flow channel 15, so as to reasonably allocate the layout space on the water circuit board body 1, which is beneficial to improving the space utilization rate on the water circuit board body 1, thus being beneficial to improving the integration degree of the integrated water circuit board 100 and being beneficial to realizing the miniaturized design of the integrated water circuit board 100.

[0119] In some embodiments of the present utility model, the water circuit board body 1 has a first area and a second area arranged in the first direction. The first area is arranged close to the first end, and the second area is arranged close to the second end. By dividing the area of the water circuit board body 1, it is convenient to allocate the installation space on the water circuit board body 1 and convenient to arrange structures such as flow channels and water inlets and outlets on the water circuit board body 1.

[0120] Among them, the water inlet 16, the first water outlet 17, the second water outlet 18, and the third water outlet 19 are all arranged at a position of the waterway board body 1 close to the first end, so as to facilitate the separate connection of the water inlet 16 with the water source, the first water outlet 17 with the drinking water equipment, the second water outlet 18 with the drinking water switch, and the third water outlet 19 with the preset functional water.

[0121] Both the first water flow channel 13 and the second water flow channel 14 are located in the first area and are arranged in the second direction, so as to facilitate the separate connection of the first water flow channel 13 with the first water outlet 17 and the second water flow channel 14 with the second water outlet 18. At least a part of the intermediate flow channel 12 is located in the second area to reasonably allocate the space of the first area and the second area, which is beneficial to improving the space utilization rate on the waterway board body 1.

[0122] Combined Figure 1 and Figure 2 , in some embodiments of the present utility model, the waterway board body 1 further has a return water flow channel 128. One end of the return water flow channel 128 is connected to the intermediate flow channel 12 and is located upstream of the pump water inlet interface 112, and the other end of the return water flow channel 128 is connected to the intermediate flow channel 12 and is located downstream of the third filter element water outlet interface 127; in the second direction, the return water flow channel 128 is located between the intermediate flow channel 12 and the third water flow channel 15.

[0123] In the second direction, arranging the return water flow channel 128 between the intermediate flow channel 12 and the third water flow channel 15 is beneficial to further improving the space utilization rate on the waterway board body 1, and is convenient for the return water flow channel 128 to be respectively connected to the pump water inlet interface 112 and the third filter element water outlet interface 127 through the intermediate flow channel 12.

[0124] After water enters the water inlet flow channel 11, it flows into the intermediate flow channel 12, and further flows into the first filter element 2. The first filter element 2 filters the water. The water with better purity after filtration flows into the intermediate flow channel 12 through the first filter element water outlet interface 111, and further flows into the third filter element 30 through the third filter element water inlet interface 126. The third filter element 30 further filters the water. The filtered water flows into the intermediate flow channel 12 through the third filter element water outlet interface 127, and flows into the return water flow channel 128 from the intermediate flow channel 12. The water flows through the return water flow channel 128 into the intermediate flow channel 12 and further flows into the booster pump 3 through the pump water inlet interface 112. The booster pump 3 pressurizes the water flowing through it, and then the water further flows into the first filter element 2 and flushes the first filter element 2. The waste water generated after flushing the first filter element 2 is discharged from the integrated waterway board 100.

[0125] Combined Figures 1 - 3, in some embodiments of the present utility model, the water circuit board body 1 further has a waste water flow channel 131, a drain port 132, and a waste water drainage interface 133 for connecting the first filter element 2. The waste water flow channel 131 communicates the drain port 132 and the waste water drainage interface 133.

[0126] When water flows through the first filter element 2, the first filter element 2 filters the water and obtains a part of water with relatively high purity and a part of waste water (concentrated water) with more impurities. Among them, the waste water with more impurities can be discharged from the first filter element 2 into the waste water flow channel 131 through the waste water drainage interface 133, and further discharged from the integrated water circuit board 100 through the drain port 132.

[0127] Among them, the drain port 132 is arranged at a position of the water circuit board body 1 close to the first end, so as to facilitate the arrangement of the drain port 132. And when the drain port 132 needs to be connected to the outside of the water purification device through a pipeline structure, it is beneficial to improve the convenience of the pipeline structure arrangement. And in the second direction, the waste water flow channel 131 is located between the water inlet flow channel 11 and the intermediate flow channel 12 to reasonably allocate the space on the water circuit board body 1, which is beneficial to further improve the space utilization rate of the water circuit board body 1.

[0128] Combined Figures 1 - 3 , in some embodiments of the present utility model, the water circuit board body 1 further has a waste water inlet interface 134 and a waste water outlet interface 135 for connecting the waste water valve 50. Both the waste water inlet interface 134 and the waste water outlet interface 135 are communicated with the waste water flow channel 131, so that the waste water valve 50 controls the on-off of the waste water flow channel 131.

[0129] The waste water valve 50 is connected to the waste water flow channel 131 through the waste water inlet interface 134 and the waste water outlet interface 135. When the waste water valve 50 is opened, a part of the waste water (i.e., concentrated water) with more impurities obtained after the first filter element 2 filters the water can be discharged from the first filter element 2 into the waste water flow channel 131 through the waste water drainage interface 133, and further discharged from the integrated water circuit board 100 through the drain port 132, which is beneficial to avoid the accumulation of waste water in the integrated water circuit board 100.

[0130] When the waste water valve 50 is in the closed state, the waste water flow channel 131 is in the disconnected state, and the waste water cannot be discharged.

[0131] As Figure 13 shown, in some embodiments of the present utility model, the widths of the water inlet flow channel 11, the flow channel upstream of the first filter element 2 in the intermediate flow channel 12, and the third water outlet flow channel 15 are 9 mm - 11 mm, and the dimensions in the thickness direction of the water circuit board body 1 are 7 mm - 9 mm.

[0132] It should be noted that the width of the flow channel is defined as L, and the dimension of the flow channel in the thickness direction of the water circuit board body 1 is defined as H. For the specific dimension illustration, please refer to Figure 13 as shown.

[0133] Preferably, the width L of the water inlet flow channel 11, the flow channels in the middle flow channel 12 upstream of the first filter element 2, and the third water outlet flow channel 15 is 9.5 mm - 10.5 mm, and the dimension H of the water inlet flow channel 11, the flow channels in the middle flow channel 12 upstream of the first filter element 2, and the third water outlet flow channel 15 in the thickness direction of the water circuit board body 1 is 7.5 mm - 8.5 mm. This is beneficial to increasing the water flow rate of the flow channels upstream of the first filter element 2, improving the water filtration efficiency of the first filter element 2, reducing energy consumption, and reducing the accumulation of impurities in the flow channels downstream of the first filter element 2 to prevent blockage of the flow channels downstream of the first filter element 2.

[0134] The widths of the flow channels in the middle flow channel 12 downstream of the first filter element 2, the first water outlet flow channel 13, and the second water outlet flow channel 14 are 7 mm - 9 mm, and their dimensions in the thickness direction of the water circuit board body 1 are 7 mm - 9 mm.

[0135] Preferably, the width L of the flow channels in the middle flow channel 12 downstream of the first filter element 2, the first water outlet flow channel 13, and the second water outlet flow channel 14 is 7.5 mm - 8.5 mm, and the dimension H of the flow channels in the middle flow channel 12 downstream of the first filter element 2, the first water outlet flow channel 13, and the second water outlet flow channel 14 in the thickness direction of the water circuit board body 1 is 7.5 mm - 8.5 mm. This is beneficial to achieving a reasonable distribution of the space on the water circuit board body 1 and reducing the material cost of the integrated water circuit board 100.

[0136] It should be noted that when the width L of the flow channels in the middle flow channel 12 downstream of the first filter element 2, the first water outlet flow channel 13, and the second water outlet flow channel 14 or the dimension H of the flow channels in the middle flow channel 12 downstream of the first filter element 2, the first water outlet flow channel 13, and the second water outlet flow channel 14 in the thickness direction of the water circuit board body 1 is less than 7.5 mm, the flow channel size is too small, and it is easy to have the problem of the flow channel restricting the water flow rate; when the width L of the flow channels in the middle flow channel 12 downstream of the first filter element 2, the first water outlet flow channel 13, and the second water outlet flow channel 14 or the dimension H of the flow channels in the middle flow channel 12 downstream of the first filter element 2, the first water outlet flow channel 13, and the second water outlet flow channel 14 in the thickness direction of the water circuit board body 1 is greater than 8.5 mm, it is easy to cause an increase in the water pressure in the flow channels, thereby increasing the risk of leakage or explosion of the integrated water circuit board 100 and affecting the reliability of the integrated water circuit board 100.

[0137] Combined with Figure 1 and Figure 2, in some embodiments of the present utility model, a third one-way valve 70 and a high-pressure switch 80 are provided in the intermediate flow channel 12. Among them, the third one-way valve 70 and the high-pressure switch 80 are arranged in sequence downstream of the water outlet interface 127 of the third filter element and upstream between the first water outlet flow channel 13 and the second water outlet flow channel 14. The third one-way valve 70 can ensure the unidirectionality of the water flowing from the third filter element 30 to the first water outlet flow channel 13 and the second water outlet flow channel 14, preventing the water from flowing back in this section of the flow channel. The high-pressure switch 80 can monitor the water pressure. When the water pressure cannot reach the preset value, the high-pressure switch 80 can cut off the power supply of the water purification device to terminate the working state of the water purification device and prevent the water purification device from being damaged.

[0138] Combined with Figure 1 and Figure 2 , in some embodiments of the present utility model, a water purification turbidity sensor 90 and a tap water turbidity sensor 101 are provided on the intermediate flow channel 12. Among them, the tap water turbidity sensor 101 is located between the pump water outlet interface 113 and the first filter element water inlet interface 110 to detect the water quality of the water flowing into the first filter element 2. The water purification turbidity sensor 90 is provided downstream of the first filter element water outlet interface 111 and is located between the first filter element water outlet interface 111 and the third filter element water inlet interface 126. The water purification turbidity sensor 90 can detect the water quality of the water filtered by the first filter element 2.

[0139] It should be noted that the first filter element 2 can be configured as a RO reverse osmosis filter element or a nanofiltration filter element, the second filter element 9 can be configured as a pre-filter element, and the third filter element 30 can be configured as a post-filter element.

[0140] Next, combined with Figures 1 - 3 describe the structure of the integrated water circuit board 100 according to the first embodiment of the present utility model.

[0141] The water circuit board body 1 has an inlet flow channel 11, an intermediate flow channel 12, a first water outlet flow channel 13, a second water outlet flow channel 14, and a third water outlet flow channel 15. One end of the inlet flow channel 11 is connected to a water source through a water inlet 16, and the other end of the inlet flow channel 11 is connected to the second filter element water inlet interface 120. An inlet valve 10 is connected to the inlet flow channel 11.

[0142] The intermediate flow channel 12 includes a first extension section 12a, a second extension section 12b, a third extension section 12c, and a fourth extension section 12d. Among them, one end of the first extension section 12a is connected to the second filter element water outlet interface 121. The second filter element 9 is connected to the inlet flow channel 11 and the first extension section 12a through the second filter element water inlet interface 120 and the second filter element water outlet interface 121 respectively. The other end of the first extension section 12a is connected to the pump water inlet interface 112, and a second control valve 20 is provided on the first extension section 12a.

[0143] One end of the water inlet section 71 of the intake module 7 is connected to the first extension section 12a, and the connection position between the water inlet section 71 and the first extension section 12a is located between the second filter element water outlet interface 121 and the second control valve 20. The other end of the water inlet section 71 is connected to the injector 713. At the same time, one end of the air intake section 72 is connected to the injector 713, and the other end of the air intake section 72 is provided with an air suction port 721. The injector 713 is simultaneously connected to one end of the mixing and discharging section 73, and the other end of the mixing and discharging section 73 is connected to the first extension section 12a.
