Description

Technical Field

[0001] This application relates to the field of water purifier technology, and in particular to wall-mounted water purifiers and water circuit systems used therein. Background Technology

[0002] With economic development, various innovative water purification and drinking water devices have emerged in the market. These devices use different technologies to purify and improve water quality, ensuring that people can drink healthy and harmless water. They have greatly improved the cleanliness of drinking water in homes and public places. The design and installation methods of household water purifiers are also constantly innovating to adapt to the needs and spatial layouts of different families. Currently, the most common installation forms of water purifiers on the market are under-sink, wall-mounted, and freestanding. Wall-mounted water purifiers are installed on the wall, saving floor space. Because of their reasonable installation location, they do not occupy valuable floor or countertop space, so related products on the market are gradually increasing.

[0003] In related technologies, traditional wall-mounted water purifiers typically introduce raw water into the reverse osmosis filter element through an inlet solenoid valve. The reverse osmosis filter element then purifies the water, producing pure water which is then output to meet the user's drinking water needs. However, in special circumstances such as power outages, traditional wall-mounted water purifiers can no longer introduce water into the reverse osmosis filter element through the inlet solenoid valve. This makes it difficult for the purifier to meet the user's emergency water needs. Furthermore, the limited water production capacity of traditional wall-mounted water purifiers makes it difficult to meet users' high-flow-rate water demands. Utility Model Content

[0004] Therefore, it is necessary to provide a wall-mounted water purifier and its water system to address the aforementioned technical problems, so as to simultaneously meet the user's needs for normal water use, emergency water use, and high-flow water use.

[0005] The first aspect of this application provides a water system for a wall-mounted water purifier. The water system includes: an inlet solenoid valve, a booster pump, and a reverse osmosis filter element connected in sequence. The inlet solenoid valve is connected to the raw water inlet end, and the pure water outlet of the reverse osmosis filter element is connected to the pure water outlet end. At least two reverse osmosis filter elements and booster pumps are configured, with each booster pump correspondingly connected to each reverse osmosis filter element. At least two booster pumps and at least two reverse osmosis filter elements are arranged in parallel between the inlet solenoid valve and the pure water outlet end. The bypass unit includes a bypass pipe and a bypass switch. The bypass inlet end of the bypass pipe is connected between the raw water inlet end and the inlet solenoid valve. The bypass outlet end of the bypass pipe is connected between the pure water outlet of the reverse osmosis filter element and the pure water outlet end. The bypass switch is installed on the bypass pipe and is used to control the opening or closing of the bypass inlet end and the bypass outlet end.

[0006] The aforementioned water system, through the bypass unit, allows the bypass switch to control the blocking of the bypass inlet and outlet ends of the bypass pipeline under normal circumstances. Raw water from the inlet end can then enter the booster pump via the inlet solenoid valve. After being pressurized by the booster pump, it enters the reverse osmosis filter, where it is purified to produce pure water. Finally, pure water flows out from the pure water outlet of the reverse osmosis filter to the pure water outlet end, meeting the user's drinking water needs under normal circumstances. In special circumstances such as a malfunction of the water purifier or a power outage, the inlet solenoid valve closes. The bypass switch controls the connection between the bypass inlet and bypass outlet of the bypass pipeline, allowing raw water from the raw water inlet to directly enter the bypass inlet and then flow out to the pure water outlet from the bypass outlet. This ensures that users can still obtain water through the water purifier in special circumstances to meet their emergency water needs. With at least two reverse osmosis filter cartridges and booster pumps, the simultaneous operation of at least two sets of booster pumps and reverse osmosis filter cartridges increases the water production capacity of the water system, thereby meeting the user's demand for high-flow-rate water use.

[0007] In one embodiment, the bypass switch is one of a ball valve, butterfly valve, gate valve, and globe valve.

[0008] In one embodiment, the water system includes a water collection channel, with the pure water outlets of at least two reverse osmosis filter cartridges connected upstream of the water collection channel, and the downstream of the water collection channel connected to the pure water outlet.

[0015] The water system also includes at least two second check valves, each of which is located between the pure water outlet of the reverse osmosis filter element and the upstream of the water collection channel. Each second check valve is connected to the pure water outlet of each reverse osmosis filter element.

[0016] The water system also includes at least two wastewater solenoid valves, which are located between the wastewater outlet and the wastewater effluent end of the reverse osmosis filter element. Each wastewater solenoid valve is connected to the wastewater outlet of each reverse osmosis filter element.

[0017] The water system also includes a flow meter, which is located between the first check valve and the pure water outlet.

[0018] The second aspect of this application also provides a wall-mounted water purifier, which includes: the water circuit system as described above; and an integrated water circuit board, which is provided with a raw water inlet and a pure water outlet. The raw water inlet is configured as a raw water inlet end, and the pure water outlet is configured as a pure water outlet end. An inlet solenoid valve, a booster pump, a reverse osmosis filter element, and a bypass unit are all installed on the integrated water circuit board.

[0019] In one embodiment, the booster pump and the bypass pipe are disposed opposite each other on both sides of the integrated water circuit board in the thickness direction.

[0020] In one embodiment, both the raw water inlet and the pure water outlet are located on the first side of the integrated water circuit board in the circumferential direction.

[0021] In one embodiment, the integrated water circuit board has at least two first filter cartridge interfaces spaced apart on the second side in the circumferential direction, and each reverse osmosis filter cartridge is correspondingly inserted into each first filter cartridge interface. The second side is the side of the integrated water circuit board that is away from the mounting surface of the wall-mounted water purifier, and the first side and the second side are connected to each other.

Both the bypass inlet and the bypass outlet are located on the side of the integrated water circuit board away from the booster pump in the thickness direction. The bypass inlet of the bypass pipe is installed on the bypass inlet, and the bypass outlet of the bypass pipe is installed on the bypass outlet. Attached Figure Description

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. 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.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0034] 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.

[0035] See Figure 1 The figure shows a schematic diagram of a wall-mounted water purifier 100 according to one embodiment of this application. In some embodiments, the wall-mounted water purifier 100 is mounted on an external surface, which is generally a vertically arranged wall, cabinet, etc. The wall-mounted water purifier 100 includes a water system 10 and a housing 20. The housing 20 provides support and protection for the water system 10 and provides an installation position for the water system 10.

[0036] See Figures 2 to 4 The water system 10 is used to realize the filtration and purification function of the wall-mounted water purifier 100. Specifically, the water system 10 includes an inlet solenoid valve 11, a booster pump 12 and a reverse osmosis filter element 13 connected in sequence.

[0037] The inlet solenoid valve 11 is connected between the raw water inlet 1 and the booster pump 12. The inlet solenoid valve 11 controls the flow of raw water from the raw water inlet 1 into the booster pump 12, which pressurizes the water to meet the pressure requirements for reverse osmosis. The raw water is then deeply purified through the reverse osmosis filter element 13. Typically, the reverse osmosis filter element 13 contains a reverse osmosis membrane. Raw water is passed through the reverse osmosis membrane under pressure, causing most pollutants to be blocked on one side of the membrane, leaving only pure water flowing out. The reverse osmosis membrane can remove most dissolved salts, heavy metals, organic matter, etc., thus purifying the raw water so that the pure water flowing out of the wall-mounted water purifier 100 meets the requirements for drinking water.

[0038] Furthermore, at least two reverse osmosis filter elements 13 and booster pumps 12 are configured, with each booster pump 12 connected to each reverse osmosis filter element 13. The at least two booster pumps 12 and at least two reverse osmosis filter elements 13 are arranged in parallel between the inlet solenoid valve 11 and the first one-way valve 14. Thus, the operation of at least two reverse osmosis filter elements 13 is controlled by the at least two booster pumps 12 respectively. This allows for the individual use of one reverse osmosis filter element 13 or the joint use of at least two reverse osmosis filter elements 13, making the water system 10 suitable for different usage scenarios. For example, by producing water simultaneously with at least two reverse osmosis filter elements 13, the water production capacity of the water system 10 can be increased to meet the user's demand for high-flow water use.

[0039] The bypass unit 15 includes a bypass pipe 151 and a bypass switch 152. The bypass inlet 1511 of the bypass pipe 151 is connected between the raw water inlet 1 and the inlet solenoid valve 11. The bypass outlet 1512 of the bypass pipe 151 is connected between the pure water outlet 131 and the pure water outlet 2 of the reverse osmosis filter element 13. The bypass switch 152 is installed on the bypass pipe 151 and is used to control the opening or closing of the bypass inlet 1511 and the bypass outlet 1512.

[0040] By using the bypass unit 15, under normal circumstances, the bypass switch 152 controls the bypass inlet 1511 and bypass outlet 1512 of the bypass pipe 151 to be blocked. Raw water from the raw water inlet 1 can enter the reverse osmosis filter element 13 through the inlet solenoid valve 11, and after being pressurized by the booster pump 12, it enters the reverse osmosis filter element 13. After being purified by the reverse osmosis filter element 13, pure water is obtained and flows out from the pure water outlet 131 of the reverse osmosis filter element 13 to the pure water outlet 2, meeting the user's drinking water needs under normal circumstances. In the event of a malfunction or power outage in the wall-mounted water purifier 100, the inlet solenoid valve 11 closes, and the bypass switch 152 controls the bypass inlet 1511 and bypass outlet 1512 of the bypass pipe 151 to be connected. This allows the raw water from the raw water inlet 1 to directly enter the bypass inlet 1511 and then flow out from the bypass outlet 1512 to the pure water outlet 2, so that users can still obtain water from the wall-mounted water purifier 100 in special circumstances to meet their emergency water needs.

[0041] Optionally, the bypass switch 152 is one of a ball valve, butterfly valve, gate valve, and globe valve. The manually operated bypass switch 152 can prevent failure due to emergencies such as power outages, improving its reliability. Furthermore, in special circumstances such as a malfunction of the wall-mounted water purifier 100 or a power outage, the bypass switch 152 can effectively open the bypass pipe 151 to supply water, meeting the user's emergency water needs.

[0042] In some embodiments, the water system 10 includes a water collection channel 4, with the pure water outlets 131 of at least two reverse osmosis filter cartridges 13 connected upstream of the water collection channel 4, and the downstream of the water collection channel 4 connected to the pure water outlet 2. By configuring the water collection channel 4, the pure water purified by at least two reverse osmosis filter cartridges 13 can be collected and flowed out to the pure water outlet 2, ensuring the stability and reliability of the pure water output. Simultaneously, the water collection channel 4 simplifies the structure of the water system 10, saving space. In other embodiments, the pure water outlets 131 of at least two reverse osmosis filter cartridges 13 can also be connected to the pure water outlet 2 via pipelines.

[0043] In a feasible embodiment, the water system 10 further includes a water storage tank 192 and a first one-way valve 14. The first one-way valve 14 is located between the bypass outlet 1512 and the downstream of the water collection channel 4, enabling unidirectional communication from the downstream of the water collection channel 4 to the pure water outlet 2. The first one-way valve 14 can stably transport the purified water from the reverse osmosis filter 13 to the pure water outlet 2 via the water collection channel 4. The first one-way valve 14 can limit the flow direction of the pure water, forming a complete purified water path between the inlet solenoid valve 11, the booster pump 12, the reverse osmosis filter 13, and the first one-way valve 14.

[0044] A water storage tank 192 is positioned upstream of the first one-way valve 14 and the water collection channel 4, allowing purified water from the reverse osmosis filter element 13 to enter the water storage tank 192 via the water collection channel 4. The water storage tank 192 stores purified water. By storing a certain amount of purified water in the water storage tank 192, users can access it at any time. Simultaneously, the water storage tank 192 provides stable outlet water pressure, ensuring a more stable and continuous water flow and a better user experience. In a feasible embodiment, the water system 10 further includes a first detection element 171, connected between the inlet solenoid valve 11 and the booster pump 12. The first detection element 171 is used to detect the total dissolved solids (TDS) value of the raw water.

[0045] In a feasible embodiment, the water system 10 further includes a second detection element 172, which is disposed at the pure water outlet 131 on the water collection channel 4. The second detection element 172 is used to detect the TDS value of the pure water, thereby obtaining the purification effect of the reverse osmosis filter element 13. Specifically, the second detection element 172 is located between the water storage tank 192 and the upstream of the water collection channel 4.

[0046] In an optional embodiment, the water system 10 further includes a first pressure detection element 161, which is disposed at the pure water outlet 131 on the water collection channel 4. The first pressure detection element 161 is used to detect the water pressure of the pure water, thereby obtaining the water pressure of the pure water. The water pressure can be used to control the water production process of the reverse osmosis filter element 13, avoiding damage to the reverse osmosis filter element 13 due to excessive water pressure. Optionally, the first pressure detection element 161 can be a pressure valve, an electronically controlled pressure switch, or a pressure sensor.

[0047] In an optional embodiment, the water system 10 further includes a second pressure detection element 162, which is disposed between the raw water inlet 1 and the inlet solenoid valve 11. The second pressure detection element 162 is used to detect the water pressure of the raw water, so that the booster pump 12 can pressurize the raw water according to the water pressure value of the second pressure detection element 162. At the same time, the setting of the second pressure detection element 162 allows raw water with a pressure lower than the preset pressure to enter the inlet solenoid valve 11, so as to avoid damage to the water system 10 due to excessive water pressure. Optionally, the second pressure detection element 162 can be a pressure valve, an electronically controlled pressure switch, or a pressure sensor.

[0048] In some embodiments, the water system 10 further includes at least two second one-way valves 18. The second one-way valves 18 are all disposed between the pure water outlet 131 of the reverse osmosis filter element 13 and the upstream 4 of the water collection channel 4. Each second one-way valve 18 is connected to the pure water outlet 131 of each reverse osmosis filter element 13. The second one-way valves 18 enable the pure water purified by the reverse osmosis filter element 13 to flow stably out to the water collection channel 4, thereby preventing the pure water produced by the reverse osmosis filter element 13 from flowing back to the reverse osmosis filter element 13.

[0049] Furthermore, during the process of transporting raw water through the bypass pipe 151, the first check valve 14 and the second check valve 18 can effectively prevent the raw water from flowing back into the reverse osmosis filter element 13, which helps to protect the reverse osmosis filter element 13 and reduces the possibility of damage to the reverse osmosis filter element 13 caused by the backflow of raw water in the bypass pipe 151 into the reverse osmosis filter element 13.

[0050] To control the discharge of wastewater generated by the reverse osmosis filter element 13, the water system 10 also includes at least two wastewater solenoid valves 190. The wastewater solenoid valves 190 are all located between the wastewater outlet 132 and the wastewater outlet 3 of the reverse osmosis filter element 13. Each wastewater solenoid valve 190 is connected to the wastewater outlet 132 of each reverse osmosis filter element 13, so that the wastewater generated by the corresponding reverse osmosis filter element 13 can be discharged through the corresponding wastewater solenoid valve 190.

[0051] In an optional embodiment, the water system 10 further includes a flow meter 191, which is disposed between the first one-way valve 14 and the pure water outlet 2. The flow meter 191 is used to measure the flow rate of pure water flowing out through the first one-way valve 4, so that according to the value of the flow meter 191, one or more reverse osmosis filter elements 13 can be selected to work to meet the needs of different water consumption.

[0052] Specifically, in the water system 10 of this application, under normal circumstances, the bypass switch 152 blocks the connection between the bypass inlet 1511 and the bypass outlet 1512. Raw water enters the inlet solenoid valve 11 from the raw water inlet 1. Before entering the inlet solenoid valve 11, the water pressure of the raw water is detected by the second pressure detection element 162. Then, the raw water enters one or more booster pumps 12 through the inlet solenoid valve 11. Before entering the booster pump 12, the TDS value of the raw water is detected by the first detection element 171. The water is pressurized by one or more booster pumps 12, and then the pressurized water is delivered to the corresponding reverse osmosis filter element 13. The pure water purified by the reverse osmosis filter element 13 flows out into the water collection channel 4 through the corresponding second one-way valve 18. The wastewater generated by the reverse osmosis filter element 13 is output to the wastewater outlet 3 through the corresponding wastewater solenoid valve 190. The TDS value of the pure water in the water collection channel 4 is detected by the second detection element 172, and the water pressure of the pure water in the water collection channel 4 is detected by the first pressure detection element 161. A portion of the pure water in the water collection channel 4 enters the water storage tank 192 for storage, and a portion of the pure water in the water collection channel 4 is transported to the pure water outlet 2 through the first one-way valve 14 and the flow meter 191 to meet the user's normal water use needs.

[0053] In the event of a malfunction or power outage in the wall-mounted water purifier 100, the inlet solenoid valve 11 is closed, and the bypass switch 152 connects the bypass inlet 1511 and the bypass outlet 1512. The water flows through the bypass pipe 151 into the flow meter 191 and then out through the pure water outlet 2 to meet the user's emergency water needs.

[0054] Typically, the components of the water system 10 are connected sequentially via pipes to achieve the water flow transportation and transmission process. To achieve integrated design of the wall-mounted water purifier 100, the wall-mounted water purifier 100 in this application also includes an integrated water circuit board 30. All components of the water system 10 can be integrated and installed on the integrated water circuit board 30, which helps reduce the area occupied by the water system 10, thereby achieving a compact design of the wall-mounted water purifier 100. It should be noted that the integrated water circuit board 30 is a preferred embodiment; in other embodiments, the components of the water system 10 can also be installed and connected via pipes.

[0055] Specifically, the integrated water circuit board 30 is provided with a raw water inlet 33, a pure water outlet 34, and a wastewater outlet 35 on its periphery. The raw water inlet 33 is connected to an external water source to introduce raw water into the wall-mounted water purifier 100. At this time, the raw water inlet 33 can serve as the raw water inlet end 1. The pure water outlet 34 is connected to a delivery pipe to discharge pure water that meets drinking requirements after being purified by the water circuit system 10. At this time, the pure water outlet 34 can serve as the pure water outlet end 2. The wastewater outlet 35 is connected to a recovery pipe to discharge wastewater that does not meet drinking requirements generated by the water circuit system 10 from the wall-mounted water purifier 100.

[0056] Furthermore, an unshown flow channel is formed within the integrated water circuit board 30. The inlet solenoid valve 11, at least two booster pumps 12, at least two reverse osmosis filter cartridges 13, and the first one-way valve 14 are sequentially installed on the integrated water circuit board 30 and connected sequentially through the flow channel, thereby achieving the filtration and purification of raw water into pure water under normal conditions.

[0057] The bypass pipe 151 is installed on the integrated water circuit board 30, and the bypass inlet 1511 of the bypass pipe 151 is located between the raw water inlet 33 and the inlet solenoid valve 11. The bypass outlet 1512 of the bypass pipe 151 is located between the first check valve 14 and the pure water outlet 34, so that the raw water inlet 33, the bypass pipe 151 and the pure water outlet 34 can be connected in sequence through the flow channel, so that raw water can be transported through the bypass unit 15 under special circumstances.

[0058] Specifically, in this application, the integrated water circuit board 30 includes a first plate 301 and a second plate 302. The first plate 301 covers the second plate 302, and the aforementioned flow channel is formed in the first plate 301 and the second plate 302. That is, the flow channel in this application is built into the interior of the integrated water circuit board 30, thereby making full use of the space occupied by the integrated water circuit board 30 in the thickness direction. This avoids the flow channel protruding outside the integrated water circuit board 30, which would affect the assembly of the filter element assembly and the components in the bypass unit 15 and the integrated water circuit board 30. This helps to improve the overall compactness and ease of installation of the water circuit system 10, reduce the volume occupied by the water circuit system 10, and make the overall space of the wall-mounted water purifier 100 more compact.

[0059] In a feasible embodiment, the integrated water circuit board 30 is also provided with a water storage outlet 36 on its periphery. The water storage outlet 36 is connected to the water storage tank 192 so that the prepared pure water that meets the drinking needs can be stored in the water storage tank 192. Thus, the pure water can be taken out on demand through the water storage tank 192, ensuring a sufficient supply of pure water and improving the user's convenience.

[0060] Preferably, in order to facilitate the connection between the wall-mounted water purifier 100 and the external pipeline and to facilitate the compact setting of the wall-mounted water purifier 100, the raw water inlet 33, the pure water outlet 34, the wastewater outlet 35 and the water storage outlet 36 are all located on the first side 31 of the integrated water circuit board 30 in the circumferential direction.

[0061] In some embodiments, the integrated water circuit board 30 is further provided with a bypass inlet 381 and a bypass outlet. Both the bypass inlet 381 and the bypass outlet are located on the side of the integrated water circuit board 30 away from the booster pump 12 in the thickness direction. The bypass inlet 1511 of the bypass pipe 151 is installed on the bypass inlet 381, and the bypass outlet 1512 of the bypass pipe 151 is installed on the bypass outlet. The bypass inlet 381 is located in the flow channel between the raw water inlet 33 and the first filter element interface 37, and the bypass outlet is located in the flow channel between the first one-way valve 14 and the pure water outlet 131. Thus, under special circumstances, raw water flows from the raw water inlet 33 through the bypass pipe 151 to the pure water outlet 34.

[0062] Preferably, in order to make full use of the space in the thickness direction of the integrated water circuit board 30, the booster pump 12 and the bypass pipe 151 are respectively arranged on both sides of the integrated water circuit board 30 in the thickness direction, so that the structure of the water circuit system 10 is more compact, reducing the space occupied by the wall-mounted water purifier 100, and making the wall-mounted water purifier 100 suitable for more application scenarios.

[0063] In some embodiments, the integrated water circuit board 30 is provided with a first filter element interface 37 on a second side 32 in the circumferential direction. The second side 32 is defined as the side of the integrated water circuit board 30 that is away from the mounting surface for installing the wall-mounted water purifier 100. The reverse osmosis filter element 13 is inserted into the first filter element interface 37. The first side 31 and the second side 32 are connected to each other. That is, the side where the first filter element interface 37 is located is different from the side where the raw water inlet 33, the pure water outlet 34, the wastewater outlet 35 and the water storage outlet 36 are located. This allows the reverse osmosis filter element 13 to avoid external pipes and components connected to the raw water inlet 33, the pure water outlet 34, the wastewater outlet 35 and the water storage outlet 36.

[0064] Specifically, at least two reverse osmosis filter elements 13 are configured. Correspondingly, the integrated water circuit board 30 has at least two first filter element interfaces 37 spaced apart on the second side 32 in the circumferential direction. Each reverse osmosis filter element 13 is inserted into each first filter element interface 37, so that the raw water can be purified simultaneously through one, two or more reverse osmosis filter elements 13 to meet the needs of different water production volumes. At the same time, when one of the reverse osmosis filter elements 13 is damaged, it can be switched to other reverse osmosis filter elements 13 to produce water, increasing the water purification path of the wall-mounted water purifier 100 and improving the water production efficiency and reliability of the wall-mounted water purifier 100.

[0065] For example, the water system 10 includes two reverse osmosis filter elements 13. Correspondingly, the second side 32 of the integrated water circuit board 30 is provided with two spaced-apart first filter element interfaces 37. The two reverse osmosis filter elements 13 are respectively inserted into the two first filter element interfaces 37. Correspondingly, the booster pump 12, the second one-way valve 18 and the wastewater solenoid valve 190 are all provided in twos and installed on the integrated water circuit board 30 in the direction of water flow.

[0066] After entering through the inlet solenoid valve 11, raw water can be filtered through a purification path consisting of one of the sequentially connected booster pumps 12, reverse osmosis filter cartridges 13, and a second one-way valve 18, and then discharged as wastewater through one of the wastewater solenoid valves 190; alternatively, after entering through the inlet solenoid valve 11, raw water can be filtered through two sequentially connected purification paths consisting of booster pumps 12, reverse osmosis filter cartridges 13, and a second one-way valve 18, and then discharged as wastewater through two wastewater solenoid valves 190, thereby increasing the water production capacity of the water system 10 to meet the demand for high-flow water use. Furthermore, to fully utilize the space of the integrated water circuit board 30, the two purification paths are distributed according to the direction of water flow on the side of the integrated water circuit board 30 closest to the first side 31 and the side furthest from the first side 31, respectively.

[0067] It should be noted that this application does not limit the number of reverse osmosis filter elements 13 to two; correspondingly, the number of booster pump 12, second check valve 18 and wastewater solenoid valve 190 is the same as the number of reverse osmosis filter elements 13.

[0068] In a feasible embodiment, the water system 10 further includes a first one-way valve 14, a first pressure detection element 161, a second pressure detection element 162, a first detection element 171, a second detection element 172, and a flow meter 191. Each component can be installed on the integrated water circuit board 30 according to the water flow direction of the water system 10. The flow channels on the integrated water circuit board 30 enable communication between the components, allowing the water system 10 to function under normal conditions, special conditions, and high-flow-rate conditions, thus meeting the user's needs for normal water use, emergency water use, and high-flow-rate water use. It should be noted that the functions of the relevant components have been described in detail in the above description of the water system 10 and will not be repeated here.

[0069] Under normal circumstances, the bypass switch 152 controls the blocking of the inlet and outlet of the bypass pipe 151. Raw water enters the integrated water circuit board 30 through the raw water inlet 33. The water pressure of the raw water is detected by the second pressure detection element 162, and then enters the two booster pumps 12 through the inlet solenoid valve 11. Before flowing into the two booster pumps 12, the TDS content of the raw water is measured by the first detection element 171. The two booster pumps 12 pressurize the raw water, and then it flows into the two reverse osmosis filter elements 13. The pure water purified by the two reverse osmosis filter elements 13 is collected in the water collection channel 4 after passing through the two second one-way valves 18. The detection element 172 measures the TDS content of the pure water in the water collection channel 4. Part of the pure water in the water collection channel 4 flows into the flow meter 191 through the first one-way valve 14, and part of the pure water in the water collection channel 4 enters the water storage tank 192 through the water storage outlet 36. Before entering the first one-way valve 14 and the water storage outlet 36, the water pressure of the pure water in the water collection channel 4 is detected by the first pressure detection element 161. After the flow meter 191 measures the flow rate of the pure water flowing out of the first one-way valve 14, it flows out from the pure water outlet 34. The wastewater generated by the two reverse osmosis filter elements 13 is collected after passing through two wastewater solenoid valves 190 and flows out from the wastewater outlet 35.

[0070] In special circumstances such as a malfunction or power outage of the wall-mounted water purifier 100, the bypass switch 152 controls the connection between the inlet and outlet of the bypass pipe 151. Raw water enters the integrated water circuit board 30 through the raw water inlet 33, enters the flow meter 191 through the bypass pipe 151, and flows out from the pure water outlet 34.

[0071] 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.

[0072] 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.
