[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0043] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0044] This utility model proposes a water system for use in a water purification device. The following describes an embodiment of the water system of this utility model.

[0045] Reference Figure 1 As shown, the water system 1000 of this embodiment includes a primary filtration component 100, a disinfectant water path 300, and a pure water path 200. The inlet of the primary filtration component 100 is connected to an external water supply system, which can specifically be a tap water supply pipeline, used to supply tap water to the water system 1000. The outlet of the primary filtration component 100 is connected to the disinfectant water path 300 and the pure water path 200, respectively. The primary filtration component 100 is used for primary filtration of tap water, which can filter out large particulate impurities such as sediment and rust in the tap water, preventing large particulate impurities from entering the disinfectant water path 300 and the pure water path 200.

[0046] The disinfectant water circuit 300 includes an electrolyzed water component 310. The inlet of the electrolyzed water component 310 is connected to the outlet of the primary filter component 100. Water filtered by the primary filter component 100 enters the electrolyzed water component 310. The electrolyzed water component 310 electrolyzes the water provided by the primary filter component 100 to produce electrolyzed water.

[0047] The pure water circuit 200 includes a secondary filtration component 230. The inlet of the secondary filtration component 230 is connected to the outlet of the primary filtration component 100. Water filtered by the primary filtration component 100 enters the secondary filtration component 230. The secondary filtration component 230 performs secondary filtration on the filtered water provided by the primary filtration component 100 to produce pure water and improve the water's cleanliness.

[0048] It should be noted that the electrolysis process involves tap water undergoing electrochemical water treatment to generate active groups with strong oxidizing properties. The hydrogen ions in the electrolyzed water can combine with chloride ions in the water to produce hypochlorous acid. Hypochlorous acid reacts with pesticide residues on fruits and vegetables, thus degrading pesticide residues. Furthermore, the generated hypochlorous acid and hydroxide ions in the electrolyzed water can chemically react with hydrogen elements in bacteria, destroying the molecular structure of bacteria and killing various harmful bacteria. Therefore, using electrolyzed water to clean fruits, vegetables, and tableware can achieve disinfection and sterilization. Thus, the electrolyzed water in this embodiment can also be called disinfectant water, giving the water purification device both water purification and disinfection functions, suitable for household and commercial use for cleaning food pesticide residues and other cleaning scenarios.

[0049] The primary filtration component 100 includes a pre-filter 111 and a post-filter 112. The inlet of the pre-filter 111 is connected to an external water supply system, and the outlet of the pre-filter 111 is connected to the water electrolysis component 310 and the secondary filtration component 230, respectively. The pre-filter 111 is used to perform primary filtration on the water supplied by the external water supply system, and the filtered water is delivered to the water electrolysis component 310 and the secondary filtration component 230. The inlet of the post-filter 112 is connected to the outlet of the secondary filtration component 230, and the post-filter 112 is used to perform secondary filtration on the water output from the pure water circuit 200. After filtration by the post-filter 112, pure water is output, thereby improving the purification effect of the water circuit system 1000.

[0050] In some embodiments, the pre-filter 111 is a combination filter element of PP cotton and activated carbon, which can effectively filter large particulate impurities such as silt and rust. The PP cotton can prevent the activated carbon layer from being blocked by large particles, which helps to extend the overall service life. The activated carbon layer has the function of adsorbing residual chlorine, odors, and other discoloration. The post-filter 112 is an activated carbon filter element, which further filters the pure water output from the pure water circuit 200, improving the filtration capacity of the water circuit system 1000.

[0051] The pre-filter 111 and the post-filter 112 adopt an integrated structure of composite filter elements, that is, an integrated composite filter element. In the embodiment, the pre-filter 111 and the post-filter 112 are installed on the same core, which reduces the space occupied by the filter elements, simplifies the pipeline connection, and helps to reduce the overall volume of the water purification device.

[0052] Reference Figures 2 to 7As shown, specifically, the composite filter element includes a first filtration chamber and a second filtration chamber. A pre-filter element 111, a combination of PP cotton and activated carbon, is installed inside the first filtration chamber. A filter element connector 113 is provided on the outer shell of the composite filter element, and the connector 113 has a first inlet, a first outlet, a second inlet, and a second outlet. The first inlet and the second outlet are respectively connected to the first filtration chamber. The first inlet is connected to an external water supply pipe, and the first outlet is connected to the inlet of the disinfectant water path 300 and the pure water path 200. In this way, tap water can enter the first filtration chamber through the first inlet, be filtered by the pre-filter element 111, and then flow to the disinfectant water path 300 and the pure water path 200 through the first outlet.

[0053] The second filter chamber is located below the first filter chamber. A post-filter element 112 is installed in the second filter chamber. The second water inlet and the second water outlet can be connected to the second filter chamber respectively. The second water inlet is connected to the outlet end of the secondary filter component 230. The second water outlet is used to connect to the external water component to deliver pure water to the external water component. The external water component can be a faucet 600 or other water-using electrical appliances.

[0054] Reference Figure 2 As shown, in some embodiments, a three-way ball valve 120 is provided between the first water inlet and the external water supply system. The three-way ball valve 120 is used to control the flow of water into the water system 1000. Additionally, a first solenoid valve 130 and a Total Dissolved Solids (TDS) detector are provided between the second water outlet and the external water-using components. The first solenoid valve 130 is used to control the flow of purified water out of the water system 1000. The TDS detector 140 is used to measure the purity of the purified water based on the detected TDS value, thereby determining whether the filter cartridge needs to be replaced.

[0055] In this embodiment, the external water-using component is a faucet 600, which has a disinfection water outlet and a pure water outlet. The disinfection water outlet is connected to the outlet of the disinfection water circuit 300, and the pure water outlet is connected to the outlet of the pure water circuit 200. The faucet 600 can output disinfected water or pure water according to the user's selection. For example, the faucet 600 can be a smart faucet, where pressing a button on the smart faucet allows selection of either disinfected water or pure water.

[0056] Reference Figure 2As shown, in some embodiments, the water system 1000 further includes a domestic water path 500, the inlet of which is connected to the outlet of the pre-filter 111. The faucet 600 also has a domestic water inlet, the outlet of which is connected to the domestic water inlet of the faucet 600. This allows users to access domestic water through the faucet 600. This domestic water undergoes primary filtration to meet daily needs such as bathing and cleaning, eliminating the need for a secondary filter assembly 230 and thus extending its lifespan.

[0057] A second solenoid valve 510 is installed in the domestic water circuit 500. The second solenoid valve 510 is used to control the opening and closing of the domestic water circuit 500. After the second solenoid valve 510 is opened, water flows directly out of the domestic water circuit 500. In addition, the primary filter assembly 100 can be connected to the disinfection water circuit 300, the pure water circuit 200 and the domestic water circuit 500 through a four-way valve, so that the primary filter assembly 100 can provide filtered water to the disinfection water circuit 300, the pure water circuit 200 and the domestic water circuit 500 respectively.

[0058] Reference Figure 2 As shown, the pure water circuit 200 includes a first pressurization circuit 210 and a first depressurization circuit 220. The first pressurization circuit 210 is located between the primary filter assembly 100 and the secondary filter assembly 230. The first pressurization circuit 210 is equipped with a first booster pump 211, which is connected to the inlet of the secondary filter assembly 230. The first pressurization circuit 210 and the first depressurization circuit 220 are arranged in parallel, which simplifies the pipeline layout and reduces assembly costs.

[0059] Specifically, the inlet of the first booster pump 211 is connected to the outlet of the pre-filter 111, and the outlet of the first booster pump 211 is connected to the inlet of the secondary filter assembly 230. The first booster pump 211 is used to increase the water pressure to meet the working pressure requirements of the secondary filter assembly 230. The first pressure relief water path 220 is equipped with a one-way valve 222, which is connected between the inlet of the first booster pump 211 and the outlet of the secondary filter assembly 230, forming a bypass pressure relief channel. In this embodiment, the one-way valve 222 only allows water to flow from the outlet of the secondary filter assembly 230 to the inlet of the first booster pump 211, while preventing the water from flowing in the opposite direction. When the pressure in the pure water path 200 rises abnormally, some water will flow back along the first pressure relief water path 220 to the inlet of the first booster water path 210, preventing high-pressure water from flowing back into the secondary filter assembly 230 and damaging the RO reverse osmosis membrane assembly.

[0060] Reference Figure 4As shown, in some embodiments, the one-way valve 222 in the first pressure relief water path 220 can be replaced by a first pressure relief valve 221, which is used to control the pressure of the pure water path 200. When the pressure of the pure water path 200 rises abnormally and exceeds a preset safety pressure threshold, the first pressure relief valve 221 opens, allowing part of the water flow to flow along the first pressure relief water path 220 to the inlet of the first booster pump 211, i.e., part of the water flow returns to the inlet of the first booster water path 210, thus preventing high-pressure water flow from damaging the secondary filter component 230.

[0061] In this embodiment, the secondary filtration component 230 includes an RO membrane filter element 231. The RO membrane filter element 231 uses an RO reverse osmosis membrane module, which has high-precision filtration capability, a desalination rate of ≥97%, and can intercept impurities such as heavy metals, bacteria, and organic matter in the water. The inlet end of the RO membrane filter element is connected to the outlet end of the first booster pump 211, and the outlet end of the RO membrane filter element is connected to the inlet end of the post-filter element 112. The first booster pump 211 increases the water pressure, providing a stable working pressure for the RO membrane filter element and ensuring the reverse osmosis filtration efficiency.

[0062] Reference Figure 2 As shown, a third solenoid valve 240 is also provided on the pure water circuit 200. The third solenoid valve 240 is located between the outlet end of the pre-filter 111 and the inlet end of the first booster pump 211. The third solenoid valve 240 is used to control the opening and closing of the pure water circuit 200. The third solenoid valve 240 is controlled by the control system of the water purification device (such as the control panel of the water purification device). It can accurately open or close the pure water circuit 200 according to user needs or system operating status to control the flow of water and make the pure water circuit 200 work more stably and reliably.

[0063] Reference Figure 2 As shown, in this embodiment, the secondary filtration component 230 has a drain outlet, which is connected to a wastewater outlet via a wastewater discharge path 250, for discharging wastewater generated by the RO membrane filter element 231. Furthermore, a fourth solenoid valve 251 is installed on the wastewater discharge path 250, which opens the wastewater discharge path 250 to allow wastewater to flow into the wastewater outlet.

[0064] Reference Figure 2 As shown, the disinfectant water circuit 300 also includes a throttle valve 301 and a first flow meter 302. The inlet of the throttle valve 301 is connected to the outlet of the primary filter assembly 100, and the outlet of the throttle valve 301 is connected to the first flow meter 302. The other end of the first flow meter 302 is connected to the inlet of the water electrolysis assembly 310. The first flow meter 302 is used to detect the water flow rate of the disinfectant water circuit 300 in real time. The throttle valve 301 is used to regulate the water flow rate of the disinfectant water circuit 300. Specifically, the throttle valve 301 can control the fluid flow rate by changing the opening of the valve orifice, and can also regulate the pressure.

[0065] Understandably, the water electrolysis unit 310 uses water electrolysis to produce electrolyzed water, which has highly oxidizing active groups, thus producing disinfectant water. When the water flow rate increases, the concentration of the prepared disinfectant water decreases; conversely, when the water flow rate decreases, the concentration of the prepared disinfectant water increases. Therefore, the opening of the throttle valve 301 can be adjusted based on the flow rate detected by the first flow meter 302. A larger opening indicates a larger flow rate, and a smaller opening indicates a smaller flow rate, thereby achieving the purpose of controlling the concentration of the disinfectant water.

[0066] Reference Figure 2 As shown, the disinfectant water circuit 300 includes a fifth solenoid valve 340, which is connected between the throttle valve 301 and the first flow meter 302. When the fifth solenoid valve 340 is open, the disinfectant water circuit 300 is open to prepare disinfectant water; when the fifth solenoid valve 340 is closed, the disinfectant water circuit 300 is closed to stop the preparation of disinfectant water. The fifth solenoid valve 340 can control the opening and closing of the disinfectant water circuit 300. The fifth solenoid valve 340 is controlled by the control system of the water purification device and can precisely open or close the disinfectant water circuit 300 according to user needs or system operating status.

[0067] Reference Figure 3 As shown, with Figure 2 The difference between the illustrated embodiments is that, Figure 3 In the embodiment shown, the first solenoid valve 130 is eliminated, and the third solenoid valve 240 is used to control the on / off state of the pure water circuit 200, and the fifth solenoid valve 340 is used to control the on / off state of the disinfectant water circuit 300. This reduces the number of components in the water circuit system 1000 and lowers the manufacturing cost.

[0068] Reference Figure 4 As shown, the disinfectant water circuit 300 includes a second pressurized water circuit 320 and a second pressure relief water circuit 330. The second pressurized water circuit 320 is located between the primary filter component 100 and the electrolyzed water component 310. The second pressurized water circuit 320 is equipped with a second pressurized pump 321, and the second pressure relief water circuit 330 is equipped with a second pressure relief valve 331.

[0069] The second booster pump 321 has its inlet connected to the outlet of the pre-filter 111, and its outlet connected to the inlet of the water electrolysis assembly 310. The second booster pump 321 is used to increase water pressure, ensuring that water flows into the water electrolysis assembly 310 at a suitable pressure to meet the water pressure requirements of the water electrolysis reaction and guarantee the efficient and stable operation of the electrolysis process. A second pressure relief valve 331 is connected between the inlet of the second booster pump 321 and the outlet of the water electrolysis assembly 310, forming another bypass pressure relief channel. When the pressure in the disinfectant water circuit 300 abnormally increases due to various reasons (such as pump failure, pipe blockage, etc.) and exceeds the preset safety pressure threshold, the second pressure relief valve 331 automatically opens, returning some water to the inlet of the second booster pump 321, thereby reducing the pressure in the water circuit, protecting the water electrolysis assembly 310 and the entire disinfectant water circuit 300, and preventing damage to the components or pipe rupture due to excessive pressure.

[0070] In addition, the disinfectant water circuit 300 includes a fifth solenoid valve 340, which is connected to the inlet end of the disinfectant water circuit 300. The fifth solenoid valve 340 can control the opening and closing of the disinfectant water circuit 300. The fifth solenoid valve 340 is controlled by the control system of the water purification device and can accurately open or close the disinfectant water circuit 300 according to user needs or system operating status.

[0071] Reference Figure 4 As shown, the disinfectant water path 300 is also equipped with a disinfectant information acquisition module 350, which is located at the outlet of the water electrolysis component 310. The disinfectant information acquisition module 350 is used to dynamically monitor the concentration of the disinfectant water. Specifically, the disinfectant information acquisition module 350 can be implemented using various technologies, such as electrochemical sensors and optical sensors.

[0072] Specifically, in this embodiment, the disinfectant information acquisition module 350 uses an ORP (oxidation-reduction potential) sensor to provide real-time feedback on the disinfection effectiveness, ensuring that the concentration of the produced disinfectant water is always kept within a suitable range to meet the requirements of different application scenarios for disinfectant water concentration.

[0073] In some embodiments, a micro / nano bubble generator 360 is further provided on the disinfectant water path 300, and the micro / nano bubble generator 360 is connected to the downstream water path of the water electrolysis component 310 in the disinfectant water path 300. The function of the micro / nano bubble generator 360 is to further process the disinfectant water treated by the water electrolysis component 310 to generate a large number of micro / nano bubbles. These micro / nano bubbles have advantages such as large specific surface area, good stability, and high mass transfer efficiency, which can significantly enhance the disinfection effect of the disinfectant water. Micro / nano bubbles can carry the active ingredients in the disinfectant water to penetrate more deeply into the surface and pores of the object being disinfected, improving the uniformity and thoroughness of disinfection, and also extending the effective action time of the disinfectant water.

[0074] In some embodiments, the water electrolysis component 310 employs a slightly acidic water electrolysis module 311, whose function is to generate highly oxidizing active groups from water filtered by the pre-filter 111 through electrochemical water treatment. Inside the slightly acidic water electrolysis module 311, through a specific electrode structure and electric field, water electrolysis produces hydrogen and oxygen. Simultaneously, impurities such as chloride ions in the water undergo a series of chemical reactions on the electrode surface, generating highly oxidizing active groups such as hypochlorite ions and hydroxyl radicals. These active groups are key components for the disinfection effect of disinfectant water.

[0075] Reference Figure 5 As shown, with Figure 4 The difference in the illustrated embodiment is that a first bypass branch 370 is added between the disinfectant water path 300 and the wastewater path 250, and a sixth solenoid valve 371 is installed on the first bypass branch 370. Since the disinfectant water may experience performance degradation due to prolonged standing time, when the performance of the disinfectant water is detected to be ineffective, the sixth solenoid valve 371 is opened, and the ineffective disinfectant water is discharged to the wastewater outlet through the first bypass branch 370.

[0076] In addition, a seventh solenoid valve 380 is installed on the disinfectant water circuit 300. The seventh solenoid valve 380 is located between the outlet of the disinfectant water circuit 300 and the faucet 600. When the performance of the disinfectant water is detected to be degraded, the sixth solenoid valve 371 is opened and the seventh solenoid valve 380 is closed to prevent the ineffective disinfectant water from being discharged from the faucet 600.

[0077] Reference Figure 6 As shown, with Figure 5 The difference in the illustrated embodiment is that a second bypass branch 520 is added between the domestic water circuit 500 and the disinfectant water circuit 300. A control valve 521 is installed on the second bypass branch 520 to control the opening and closing of the second bypass branch 520. The control valve 521 can be a solenoid valve or other type of on / off valve. It is understood that the domestic water circuit 500 is divided into two branches: one branch connects to the faucet 600, and the other branch connects to the disinfectant water circuit 300. The outlet of the second bypass branch 520 is specifically connected between the outlet of the water electrolysis assembly 310 and the faucet 600.

[0078] When a user prepares disinfectant, the second bypass branch 520 is opened by the control valve 521, connecting the domestic water circuit 500 and the disinfectant water circuit 300. The disinfectant information acquisition module 350 dynamically monitors the concentration of the disinfectant. The water flow from the domestic water circuit 500 can flow into the disinfectant water circuit 300, thus diluting the concentration of the disinfectant. Specifically, the opening of the control valve 521 can be adjusted according to the concentration requirements, thereby adjusting the concentration of the disinfectant according to the water usage needs.

[0079] Reference Figure 7 As shown, with Figures 4-6 The difference in the illustrated embodiment is that the disinfectant water path 300 and the pure water path 200 share a third pressurization water path 700. The third pressurization water path 700 pressurizes both the disinfectant water path 300 and the pure water path 200, eliminating the need for separate first pressurization water paths 210 and 320. Specifically, the third pressurization water path 700 includes a third pressurization pump 710. The inlet of the third pressurization pump 710 is connected to the outlet of the pre-filter 111, and the outlet of the third pressurization pump 710 is connected to the inlet of both the disinfectant water path 300 and the pure water path 200, specifically to the inlet of the third solenoid valve 240 and the fifth solenoid valve 340.

[0080] Understandably, when purified water needs to be prepared, the third solenoid valve 240 is opened, connecting the third booster pump 710 to the purified water circuit 200. At this time, the fifth solenoid valve 340 is closed, disconnecting the disinfectant water circuit 300. The third booster pump 710 pressurizes the purified water circuit 200 to meet the working pressure requirements of the secondary filtration component 230.

[0081] When disinfectant water needs to be prepared, the fifth solenoid valve 340 is opened and the third solenoid valve 240 is closed, connecting the third booster pump 710 to the disinfectant water circuit 300 and disconnecting the pure water circuit 200. The third booster pump 710 pressurizes the disinfectant water circuit 300 to meet the working pressure requirements of the water electrolysis assembly 310.

[0082] Reference Figure 7 As shown, the embodiment also includes a third pressure relief water path 800, which includes a third pressure relief valve 810. The inlet of the third pressure relief valve 810 is connected to the inlet of the third booster pump 710, and the outlet of the third pressure relief valve 810 is connected to the outlet of the secondary filter assembly 230. It is understood that when the pressure in the third booster water path 700 abnormally increases, exceeding a preset safety pressure threshold, the third pressure relief valve 810 opens, directing some water flow along the third pressure relief water path 800 to the inlet of the third booster pump 710, thus preventing high pressure from damaging the secondary filter assembly 230 or the water electrolysis assembly 310.

[0083] Reference Figure 7 As shown, an eighth solenoid valve 720 is installed at the inlet end of the third pressurized water circuit 700 and the third depressurized water circuit 800. The eighth solenoid valve 720 is used to control the opening and closing of the third pressurized water circuit 700 and the third depressurized water circuit 800. Specifically, when it is necessary to prepare disinfected water or purified water, the eighth solenoid valve 720 is opened, and the operation of the purified water circuit 200 and the disinfected water circuit 300 can be selected by controlling the opening and closing of the third solenoid valve 240 and the fifth solenoid valve 340.

[0084] In some embodiments, a second flow meter 390 is provided on the disinfectant water circuit 300. The second flow meter 390 can detect the flow rate of the disinfectant water prepared by the disinfectant water circuit 300, thereby providing real-time feedback on the working status of the disinfectant water circuit 300. The flow rate of the disinfectant water can also be controlled according to the seventh solenoid valve 380 to meet the user's needs.

[0085] The following is for reference. Figures 2 to 4 The working process of the water purification device according to the embodiments of this utility model is described in detail.

[0086] When a user needs to prepare purified water, the third solenoid valve 240 and the first booster pump 211 are opened. After primary filtration by the pre-filter cartridge 111, the water enters the purified water circuit 200. The first booster pump 211 pressurizes the water after primary filtration to the pressure required by the RO membrane filter cartridge 231. After secondary filtration by the RO membrane filter cartridge 231, the water flows from the outlet of the RO membrane filter cartridge 231 to the post-filter cartridge 112, completing high-precision filtration. After being filtered again by the post-filter cartridge 112, the water is discharged from the faucet 600.

[0087] When a user needs to prepare disinfectant water, the fifth solenoid valve 340 and the second booster pump 321 open. Water flows through the pre-filter 111 for primary filtration and then enters the disinfectant water circuit 300. The second booster pump 321 pressurizes the filtered water to the pressure required by the water electrolysis assembly 310. After electrolysis by the water electrolysis assembly 310, electrolyzed water is produced and then discharged from the faucet 600. When a decrease in the performance of the disinfectant water is detected, the sixth solenoid valve 371 is opened, and the ineffective disinfectant water is discharged to the wastewater outlet through the first bypass branch 370.

[0088] When domestic water is needed, the second solenoid valve 510 opens, while the third solenoid valve 240 and the fifth solenoid valve 340 are both closed. After the water flows through the pre-filter 111 for primary filtration, it is directly discharged from the domestic water circuit 500 to the faucet 600, allowing for quick access to domestic water.

[0089] When users need to adjust the concentration of disinfectant, they open control valve 521 to connect the domestic water circuit 500 and the disinfectant water circuit 300. The water flow from the domestic water circuit 500 flows into the disinfectant water circuit 300, thereby diluting the concentration of disinfectant and meeting the user's needs for different disinfectant concentrations.

[0090] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
