Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0037] See Figure 1As shown, an embodiment of this application provides a water circuit board assembly 100, which can be used for the pure water supply of an integrated water purifier and heat pump. It can simplify the water circuit structure, reduce the volume, and improve the space utilization and installation efficiency of the whole machine.

[0038] It should be noted that the water circuit board assembly 100 provided in this application can be used in any water supply equipment, such as a cold drink machine or a water purifier, as long as it can achieve the purification of raw water and the supply of pure water. For ease of understanding, this application applies the water circuit board assembly 100 to an integrated water purifier and heat pump, which is only for illustrative purposes.

[0039] Continue reading Figure 2 As shown, specifically, the water circuit board assembly 100 includes a main body 110, a first filter element holder 120, and a second filter element holder 130. The first filter element holder 120 and the second filter element holder 130 are both installed on the main body 110. The main body 110 is provided with several water channels to connect the first filter element holder 120 and the second filter element holder 130. The raw water is purified into drinkable pure water through the filter element installed in the filter element holder.

[0040] Continue reading Figure 3 and Figure 4 As shown, exemplarily, the main body 110 is provided with a first raw water inlet 111, a first water passage 112, a second water passage 113, a third water passage 114, and multiple first pure water outlets 115. During operation, raw water enters the main body 110 through the first raw water inlet 111 and flows through each water passage to the first filter cartridge holder 120 and the second filter cartridge holder 130. After purification into potable pure water, it can be discharged from the first pure water outlets 115 to meet the user's water needs.

[0041] In some embodiments, the first pure water outlet 115 has three outlets, namely, a room temperature pure water outlet 1153, a hot water tank replenishment outlet 1152, and a hot water outlet 1151.

[0042] Specifically, the ambient temperature pure water outlet 1153 is connected to the heating system to directly heat the pure water during output, providing ready-to-drink hot water. The hot water tank replenishment outlet 1152 is connected to the hot water tank to allow pure water to enter the hot water tank from the main body 110 through the replenishment solenoid valve. When the liquid level in the hot water tank is lower than the set level, water can be added to the hot water tank. The ambient temperature pure water outlet 1153 can directly provide pure water to users to meet their direct drinking needs.

[0043] In some embodiments, a solenoid valve may be installed at both the ambient temperature pure water outlet 1153 and the hot water tank replenishment outlet 1152 to achieve automatic control of pure water output.

[0044] Continue reading Figure 5As shown, for example, the first filter cartridge 120 is provided with a second raw water inlet 121, a pretreated water outlet 122, a retreated water inlet 123, and a second pure water outlet 124. The second raw water inlet 121 is connected to the first raw water inlet 111, and the second pure water outlet 124 is connected to each of the first pure water outlets 115 through the third water passage 114.

[0045] Understandably, the first raw water inlet 111 and the second raw water inlet 121 are also connected through the water passage inside the main body 110, so that the raw water is introduced into the first filter element seat 120 and pre-treated by the filter element installed in the first filter element seat 120.

[0046] In some embodiments, a pressure reducing valve may be provided in the water passage between the first raw water inlet 111 and the second raw water inlet 121 to ensure that the inlet pressure of the raw water does not exceed the set value, to avoid impact on downstream workpieces due to fluctuations in water source pressure, and to prevent excessive water pressure from damaging sensitive devices such as valves and instruments.

[0047] In some embodiments, the third water path 114 may be equipped with a TDS (Total Dissolved Solids) sensor, which can measure the total dissolved solids concentration in the water and obtain the purification quality of the pure water.

[0048] Continue reading Figure 6 and Figure 7 As shown, for example, the second filter cartridge 130 is provided with a pre-treated water inlet 131 and a re-treated water outlet 132. The pre-treated water inlet 131 is connected to the pre-treated water outlet 122 through the first water passage 112, and the re-treated water outlet 132 is connected to the re-treated water inlet 123 through the second water passage 113.

[0049] Specifically, the pretreated water inlet 131 and pretreated water outlet 122 are connected through the first water passage 112, allowing the water pretreated by the filter element installed in the first filter element holder 120 to be transported to the second filter element holder 130 for further purification by the filter element installed in the second filter element holder 130. The retreated water outlet 132 and retreated water inlet 123 are then connected through the second water passage 113, allowing the water retreated by the filter element installed in the second filter element holder 130 to be transported back to the first filter element holder 120, ultimately purifying the water to the user's desired pure water.

[0050] In some embodiments, the water circuit board assembly 100 further includes a composite filter element 140, which is mounted on the first filter element holder 120. The composite filter element 140 includes a first activated carbon filter element 141 and a second activated carbon filter element 142. The first activated carbon filter element 141 is connected to the second raw water inlet 121 and the pretreated water outlet 122, respectively, and the second activated carbon filter element 142 is connected to the retreated water inlet 123 and the second pure water outlet 124, respectively.

[0051] Specifically, the first activated carbon filter element 141 is a PAC (Powdered Activated Carbon) filter element, which can effectively adsorb organic matter, odors, residual chlorine and some heavy metals in the water, improve water quality, and has a fast adsorption speed, making it suitable for the high flow rate requirements in the pretreatment process. The second activated carbon filter element 142 can purify the water a third time to finally obtain the pure drinking water required by the user.

[0052] Furthermore, the water circuit board assembly 100 also includes a reverse osmosis filter element 150, which is installed on the second filter element seat 130. The pre-treated water inlet 131 and the re-treated water outlet 132 are both connected to the reverse osmosis filter element 150.

[0053] Specifically, the reverse osmosis filter cartridge 150 is an RO (Reverse Osmosis) membrane filter cartridge, which can efficiently remove pollutants such as dissolved salts, heavy metals, bacteria, and viruses from water using reverse osmosis technology, providing pure water that can be drunk directly.

[0054] In some embodiments, the water circuit board assembly 100 further includes a solenoid valve and a flow meter 170 installed on the main body 110. The solenoid valve is connected to the pretreated water outlet 122 and the flow meter 170, respectively, and the flow meter 170 is connected to the solenoid valve and the pretreated water inlet 131, respectively.

[0055] Specifically, the solenoid valve and flow meter 170 are installed on the first water passage 112 to control the flow rate of water pretreated by the first activated carbon filter element 141 into the reverse osmosis filter element 150. The pretreated water passes sequentially through the solenoid valve and flow meter 170. The solenoid valve controls the flow of pretreated water, while the flow meter 170, composed of a Hall effect element and an impeller, obtains the flow rate of the pretreated water, calculates the lifespan of the first activated carbon filter element 141, and selects an appropriate replacement time. Installing the flow meter 170 downstream of the solenoid valve allows the valve to act as a "buffer," isolating upstream water hammer, pressure fluctuations, and impurity impacts, thereby extending the lifespan of the flow meter 170 and improving measurement accuracy, thus protecting the flow meter 170.

[0056] Furthermore, the water circuit board assembly 100 also includes a pressure stabilizing pump 180, which is connected to the flow meter 170 and the pre-treated water inlet 131.

[0057] Specifically, the pressure stabilizing pump 180 can eliminate water pressure fluctuations, ensure stable water flow, and prevent equipment damage or performance degradation due to insufficient or excessive pressure. After passing through the impeller of the flow meter 170, the pretreated water enters the pressure stabilizing pump 180 from the first water passage 112 of the main body 110. After being pressurized, it enters the reverse osmosis filter element 150 through the pretreated water inlet 131 of the second filter element holder 130.

[0058] In some embodiments, a TDS (Total Dissolved Solids) sensor is also provided in the flow area of ​​the first water path 112 to measure the total dissolved solids concentration in the pretreated water. The TDS sensor of the first water path 112 is installed upstream of the solenoid valve 160, so as to compare the total dissolved solids concentration measured by the TDS sensor of the third water path 114 to obtain the purification effect of the raw water treatment.

[0059] In some embodiments, the second filter element holder 130 is further provided with a wastewater outlet 133, and the main body 110 is further provided with a fourth water passage 116, one end of which is connected to the wastewater outlet 133.

[0060] Specifically, after the pretreated water is filtered by the reverse osmosis filter element 150, it forms retreated water with fewer impurities and concentrated water with more impurities. The retreated water flows through the second water channel 113 to the second activated carbon filter element 142 for purification to obtain pure water. The concentrated water is discharged through the wastewater outlet 133 to the fourth water channel 116.

[0061] For reference Figure 8 As shown, the main body 110 is further provided with a concentrated water outlet 118, which is connected to the end of the fourth water channel 116 away from the wastewater outlet 133, so as to discharge concentrated water with more impurities.

[0062] Furthermore, the fourth water channel 116 is also equipped with a solenoid valve, which is installed on the main body 110 to control the automatic discharge of concentrated water.

[0063] In some embodiments, the main body 110 is further provided with a fifth water passage 117, one end of which is connected to the fourth water passage 116, and the other end is connected to the portion of the first water passage 112 located between the pressure stabilizing pump 180 and the flow meter 170.

[0064] Specifically, by setting up the fifth water channel 117, the concentrated water can re-enter the first water channel 112, and then be filtered again through the reverse osmosis filter element 150, realizing the concentrated water return function, realizing the recycling of concentrated water, and improving the water utilization rate.

[0065] Furthermore, a solenoid valve is installed along the path of the fifth water channel 117 to control the connection of the fifth water channel 117 and control the concentrated water to flow into the fifth water channel 117 via the fourth water channel 116.

[0066] Furthermore, a check valve is installed upstream of the solenoid valve in the fifth water passage 117 to restrict the flow direction of the concentrate, so that the concentrate can only flow into the first water passage 112 through the fifth water passage 117, while the pretreated water in the first water passage 112 cannot flow out through the fifth water passage 117.

[0067] In some embodiments, the main body 110 is further provided with a sixth waterway 119, the two ends of which are connected to the first waterway 112 and the third waterway 114 respectively.

[0068] Specifically, after the water supply equipment stops working, over time, some concentrated water will seep through the RO membrane and mix into the pure water. If the equipment has not been started for a long time, when drinking pure water again, the solenoid valve at the first pure water outlet 115 can be closed, allowing the pure water to flow through the third water path 114 to the first water path 112, and then back into the reverse osmosis filter element 150, ensuring the user's drinking water health.

[0069] Furthermore, a solenoid valve is installed on the path of the sixth water channel 119 to control the connection of the sixth water channel 119 and control the pure water to flow into the first water channel 112 via the third water channel 114.

[0070] Furthermore, a check valve is installed upstream of the solenoid valve in the sixth water channel 119 to restrict the flow direction of pure water, so that the pure water that needs to be filtered again can only flow into the first water channel 112 through the third water channel 114, while the pre-treated water in the first water channel 112 cannot flow to the third water channel 114 through the sixth water channel 119.

[0071] Embodiments of this application also provide a water supply device, including the water circuit board assembly 100 in any of the above embodiments.

[0072] Specifically, the water supply device can be an integrated water purifier and heater, a whole-house water purification system, a kitchen water purifier, a water dispenser, a cold drink machine, etc., and no specific limitation is required here.

[0073] This embodiment includes the water circuit board assembly 100 of any of the above embodiments, and therefore has all the beneficial effects of the water circuit board assembly 100 of any of the above embodiments, which will not be described in detail here.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
