[0057] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0058] Reference below Figure 1-Figure 7 A beverage purifier assembly 100 according to an embodiment of the present application is described.

[0059] According to the beverage purifier assembly 100 of the embodiment of the present application, it includes: a first pipeline 1, a water purification module 10, a reverse water supply device 54 and a functional module 20, the first pipeline 1 is connected to a water source, the water purification module 10 is arranged downstream of the first pipeline 1 and is used to filter the medium passing through the water purification module 10, the water purification module 10 is provided with a purified water outlet, the reverse water supply device 54 is selectively connected to the purified water outlet, the functional module 20 is provided with a functional inlet, and the functional inlet is connected to the purified water outlet, and the functional module 20 is used to perform at least one of heating, cooling and ice making on the filtered medium.

[0060] In the related art, the water purifier needs to be separately connected to the pipeline machine to achieve subsequent heating, cooling or ice making. The pipeline machine itself does not have a water purification function and must rely on external water purification equipment to provide purified water, which increases the connection complexity and installation cost of the equipment. Users need to purchase the water purifier and the pipeline machine separately, which brings inconvenience to users.

[0061] According to the water purifier assembly 100 of the embodiment of the present application, the first pipeline 1 is used as the water source inlet, which is responsible for introducing external water into the system. After the water flows through the first pipeline 1, it enters the water purification module 10. After being filtered by the water purification module 10, the water flows out from the water purification outlet of the water purification module 10 and reaches the drinking standard. The functional inlet of the functional module 20 is directly connected to the water purification outlet. The functional module 20 performs at least one of heating, cooling and ice making on the filtered medium. At least one of the functions of heating, cooling and ice making is integrated inside the water purifier assembly 100, without the need to connect additional external equipment. The reverse water supply device 54 can be selectively connected to the water purification outlet.

[0062] Since the water purifier assembly 100 in the embodiment of the present application integrates the functional module 20, there is no need to install an independent pipeline machine. When hot water is needed, the purified water enters the functional module 20, and the corresponding module of the functional module 20 works to meet the user's immediate demand for hot water. When cold water is needed, the corresponding module in the functional module 20 works, and the water can be quickly cooled down by the operation of the refrigeration compressor to provide cold water. When ice making is needed, the corresponding module in the functional module 20 works to convert the purified water into ice cubes, so that the water purifier assembly 100 does not need to be additionally connected to a pipeline machine to achieve the function of adding or refrigeration or ice making, thereby improving functionality. The reverse water supply device 54 can be selectively connected to the purified water outlet. When the reverse water supply device 54 is connected, domestic water can be provided for washing vegetables, washing dishes, washing, etc., so that the water purifier is no longer limited to providing drinking water, but can also meet part of the needs of household domestic water.

[0063] The water purifier assembly of the embodiment of the present application integrates the functions of water purification, heating, cooling, ice making and domestic water supply into one, avoiding many inconveniences caused by the separation of the water purifier and the pipeline machine in the traditional mode, greatly improving the functionality of the water purifier, and providing users with a more comprehensive and convenient water experience. At the same time, by integrating at least one of the functions of heating, cooling and ice making into the water purifier assembly 100, the long connection line between the pipeline machine and the water purifier is avoided. The connecting pipelines between the modules in the water purifier assembly 100 of this embodiment are relatively short and concentrated inside the device. The connecting pipelines from the water purification outlet to the functional module 20 can be closely arranged inside the water purifier without occupying additional external space for wiring, which not only reduces the space occupation caused by wiring, but also reduces the safety hazards and aesthetic problems caused by the exposure of the pipeline. The functional module 20 is integrated into the water purifier assembly 100, making the entire device structure more compact. The water purifier assembly 100 with the integrated functional module 20 can be placed more flexibly without affecting the overall layout and operation space of the kitchen or use space, thereby improving the overall utilization rate and aesthetics of the space.

[0064] According to some embodiments of the present application, the water purifier assembly 100 further includes a second pipeline 5, which connects the purified water outlet with the reverse water supply device 54, and a first control valve 52 is provided on the second pipeline 5, and the first control valve 52 is suitable for controlling the conduction state of the second pipeline 5.

[0065] It can be understood that, in the water purifier assembly 100, when the first control valve 52 is closed, the water at the purified water outlet enters the functional module 20 to meet the drinking water needs such as heating, cooling, and ice making; when the first control valve 52 is opened, the second pipeline 5 is connected, and the purified water flows to the reverse water supply device 54 through the second pipeline 5 to provide living water for washing, cleaning fruits and vegetables, etc., to meet the water needs of various scenarios.

[0066] According to the water purifier assembly 100 of some embodiments of the present application, the first control valve 52 is configured as a water pressure switch.

[0067] In daily use, when the reverse water supply device 54 is not turned on, the functional module 20 operates normally, and the purified water flows to the functional module 20 through the purified water outlet for heating, cooling or ice making operations. At this time, the water pressure of the main channel through which the water flows is stable, and the water pressure switch is in a closed state, ensuring that the water flow is stably supplied to the functional module 20 to meet the user's drinking water needs. When the reverse water supply device 54 is turned on, the direction of the water flow changes, and part of the water flows to the second pipeline 5, causing the water pressure of the second pipeline 5 to drop. After the water pressure switch detects the change in water pressure, it automatically conducts the second pipeline 5, allowing water to flow smoothly to the reverse water supply device 54, meeting the user's daily water needs such as washing, washing fruits and vegetables. When the reverse water supply device 54 is turned off, the water pressure in the main channel returns to normal, and the water pressure switch closes the second pipeline 5 again to ensure that the water flow returns to the state of supplying water to the functional module 20. Based on the water pressure switch control method, not only the automatic switching of the two water use modes is realized without the need for complex manual operations by the user, but also the reaction is sensitive and can respond quickly according to changes in water pressure, thereby improving the convenience and stability of the water purifier assembly 100. At the same time, the water pressure switch has a simple structure and high reliability, which reduces possible failures caused by complex mechanical structures and reduces maintenance costs.

[0068] According to the water purifier assembly 100 of some embodiments of the present application, the reverse water supply device 54 is configured as a faucet, and the faucet is selectively connected to the second pipeline 5 .

[0069] The reverse water supply device 54 is constructed as a faucet and is selectively connected to the second pipeline 5. When the second pipeline 5 is in a connected state with the faucet, the water purifier can not only provide purified, heated, cooled or iced drinking water, but also supply users with daily living water like an ordinary faucet, such as for washing vegetables, washing dishes, washing, etc., expanding the function of the water purifier from simple drinking water to multiple scenarios of household water use, meeting the user's diverse water needs, and there is no need to equip these domestic water use scenarios with other water sources or equipment, which greatly improves the practicality and functionality of the water purifier.

[0070] According to some embodiments of the present application, the water purifier assembly 100 further includes a first one-way valve 62 , which is disposed on the second pipeline 5 and is suitable for limiting the one-way flow of the medium in the second pipeline 5 toward the reverse water supply device 54 .

[0071] The first one-way valve 62 is arranged on the second pipeline 5 to limit the one-way flow of the purified medium in the second pipeline 5 to the reverse water supply device 54. When the water purifier is in a normal water-drawing state, the first control valve 52 is opened, and the purified water can smoothly pass through the first one-way valve 62 and flow along the second pipeline 5 to the reverse water supply device 54 to meet the water demand. When the water purifier stops drawing water, the first control valve 52 is closed, or in other working states of the water purifier, the first one-way valve 62 will prevent water from flowing in the opposite direction, that is, prevent water from flowing back from the reverse water supply device 54 to the second pipeline 5. It can be understood that when the water purifier stops drawing water, there may be a certain pressure change in the reverse water supply device 54, which may be water pressure fluctuations caused by faucet operation at the user end, or factors such as water inertia, which may cause water to flow back from the reverse water supply device 54 to the second pipeline 5. The returned water may have come into contact with the outside world and been contaminated to a certain extent. When it flows back into the second pipeline 5, it will re-contaminate the originally purified water and affect the water quality of the water purifier. The presence of the first one-way valve 62 effectively avoids this situation and ensures that the water in the second pipeline 5 always flows toward the reverse water supply device 54, maintaining the purity and order of the water flow inside the water purifier.

[0072] According to some embodiments of the water purifier assembly 100 of the present application, the water purification module 10 includes a first filter device 2, a second filter device 3 and a third filter device 4. The first filter device 2 is provided with a first filter inlet 21 and a first filter outlet 22, and the first filter inlet 21 is connected to the first pipeline 1; the second filter device 3 is provided with a second filter inlet 31 and a second filter outlet 32, and the second filter inlet 31 is connected to the first filter outlet 22; the third filter device 4 is provided with a third filter inlet 41 and a third filter outlet 42, and the third filter device 4 is provided downstream of the second filter device 3.

[0073] The first pipeline 1 is used as the water source access end, which is responsible for introducing the raw water from the outside into the subsequent entire system. After the raw water enters, it first reaches the first filter device 2. The first filter inlet 21 and the first filter outlet 22 of the first filter device 2 work together, and can use filter materials such as filter screens and filter cotton to effectively intercept large-volume particle impurities in the raw water, such as mud and large particles of colloid, etc., to lay a good foundation for the subsequent filtering process. The water that has been initially filtered then flows into the second filter device 3. The second filter device 3 works to remove microorganisms, impurities, etc. in the medium retained in the second filter device 3. The water that has been circulated and purified by the second filter device 3 flows to the third filter device 4, where it is filtered more finely to further ensure the purity of the water quality. Finally, the water that has been filtered layer by layer flows to the functional module 20 and the reverse water supply device 54. Through the sequential action of these three-stage filtering devices, the water purifier assembly 100 can provide users with high-quality, safe and reliable drinking water.

[0074] According to some embodiments of the water purifier assembly 100 of the present application, the water purification module 10 also includes a third pipeline 6, one end of the third pipeline 6 is connected to the second filter outlet 32, and the other end of the third pipeline 6 is connected to the second filter inlet 31. The third pipeline 6 is provided with a second control valve 61. The second control valve 61 can selectively control the conduction state of the third pipeline 6 according to the conduction state of the second pipeline 5 by the first control valve 52, so as to be suitable for circulating filtration of the medium in the second filter device 3.

[0075] One end of the third pipeline 6 is connected to the second filter outlet 32 ​​of the second filter device 3, and the other end is connected to the second filter inlet 31, and a second control valve 61 is installed on the third pipeline 6. When the water purifier assembly 100 is in a non-water intake state, that is, after the first control valve 52 closes the second pipeline 5, the second control valve 61 will open the third pipeline 6 according to the closed state of the first control valve 52. At this time, the medium that has been filtered in the second filter device 3 but has produced a small amount of microorganisms and impurities during the static process will enter the third pipeline 6 through the passage formed by the opening of the second control valve 61 and start circulating filtration. During the circulation process, the second filter device 3 works to remove microorganisms, impurities, etc. in the medium remaining in the second filter device 3. After circulation, the impurity content of the medium remaining in the second filter device 3 is greatly reduced, and the source of aquatic odor substances is reduced.

[0076] By setting up a third pipeline 6, the third pipeline 6 is connected to the outlet and the inlet of the second filter device 3, and a second control valve 61 is provided on the third pipeline 6. The second control valve 61 can control the conduction state of the third pipeline 6 according to the conduction state of the second pipeline 5 by the first control valve 52, so that the stored water in the second filter device 3 is circulated and filtered in the third pipeline 6. During the circulation process, the second filter device 3 continues to work and continuously removes microorganisms, impurities, etc. in the water. After multiple cycles, the impurity content is greatly reduced, and the source of aquatic odor substances is reduced. The water finally supplied has less impurities and less odor, which greatly improves the drinking taste.

[0077] In some embodiments of the present application, the other end of the third pipeline 6 is communicated with the inlet of the boost pump 23 and is connected to the second filter inlet 31 of the second filter device 3 through the boost pump 23 .

[0078] The booster pump 23 performs a pressurization process on the water entering the inlet of the booster pump 23. Since reverse osmosis membrane filtration requires a certain pressure to allow water to pass smoothly and achieve effective filtration and separation, the pressure provided by the booster pump 23 can ensure that the water enters the second filter device 3 at a suitable pressure during the circulation process. The pressurized water enters the second filter device 3 again, and the reverse osmosis membrane can more effectively intercept harmful substances such as microorganisms, impurities, and ions in the water. During the circulation process of the third pipeline 6, the odorous substances, microbial metabolites and various impurities in the water are continuously filtered and intercepted by the reverse osmosis membrane. As the number of cycles increases, the water quality is gradually purified. The circulating filtration structure formed by the third pipeline 6, the booster pump 23 and the second filter device 3 can effectively circulate and purify the water that may be contaminated after the water purifier is left to stand. When taking water again, the water that has been circulated and filtered has removed most of the odorous substances and impurities, greatly improving the taste of drinking water and making the water purer and more delicious. At the same time, this circulation filtration can also reduce the accumulation of microorganisms and impurities on the surface of the reverse osmosis membrane, reduce the risk of reverse osmosis membrane being blocked, extend the service life of the reverse osmosis membrane, and thus reduce the maintenance cost of the water purifier. In addition, the quality of drinking water is guaranteed, the concerns about water quality safety are reduced, and the user experience is improved.

[0079] In some embodiments of the present application, the second control valve 61 is turned on after the disconnection time of the first control valve 52 reaches a preset time.

[0080] It is understandable that during the use of the water purifier, the first control valve 52 controls the water supply process to the reverse water supply device 54. When the water extraction operation is completed, the first control valve 52 is disconnected immediately, and the water purifier enters a static state. During the static period, the medium remaining in the filter device and the pipeline is prone to breed bacteria, algae and other microorganisms. Microorganisms and impurities will gradually gather and precipitate due to lack of flow. The longer the static time, the greater the possibility of producing aquatic odor substances. The purpose of setting a preset time is to prevent the water purifier assembly 100 from being too static for too long and causing the water quality to deteriorate. When the disconnection time of the first control valve 52 reaches the preset time, it means that the water purifier has been static for a long enough time, and substances that affect the taste and water quality have been produced in the water. At this time, the second control valve 61 is turned on, and the third pipeline 6 is connected, so that the water in the second filter device 3 and the connected pipeline can circulate. Through the circulation filtration of the second filter device 3, the microorganisms, impurities and odor substances in the water are removed, thereby ensuring that the water quality is excellent when the water is taken again, and the taste is not affected. Therefore, the second control valve 61 is turned on after the first control valve 52 is disconnected for a preset time in order to purify the water that has been standing for too long in time to ensure the quality of the water output from the water purifier. The preset time is t, where 15min≤t≤25min.

[0081] In some embodiments of the present application, a water supply end 51 is further included, and the water supply end 51 is connected to the reverse water supply device 54 and the second pipeline 5 .

[0082] According to some embodiments of the water purifier assembly 100 of the present application, the second filter device 3 is constructed as a reverse osmosis membrane filter element, and the water purification module 10 also includes: a booster pump 23, the booster pump 23 is provided with a booster pump 23 inlet and a booster pump 23 outlet, the booster pump 23 inlet is connected to the first filter outlet 22, and the booster pump 23 outlet is connected to the second filter inlet 31.

[0083] The second filter device 3 uses a reverse osmosis membrane filter. The reverse osmosis membrane is a semi-permeable membrane with fine pores. The pore size is small, usually at the nanometer level. The characteristics of the reverse osmosis membrane enable the reverse osmosis membrane to effectively block most impurities, ions, bacteria and viruses, etc., and only allow water molecules to pass through, thereby achieving deep purification of the water. However, in order for water to be filtered smoothly through the reverse osmosis membrane, it is necessary to overcome certain resistance, because the filtration process of the reverse osmosis membrane is carried out against the natural osmosis direction. The pressure on the raw water side must be large enough to force water molecules to overcome the osmotic pressure and pass through the reverse osmosis membrane to reach the pure water side. The inlet of the booster pump 23 is connected to the first filter outlet 22. The booster pump 23 sucks in the water that has been preliminarily filtered by the first filter device 2. Then, the booster pump 23 applies additional pressure to the water through the internal mechanical structure or electrical drive to increase the water pressure. The outlet of the booster pump 23 is connected to the second filter inlet 31, and the pressurized water is transported to the second filter device 3. When water with sufficient pressure enters the reverse osmosis membrane filter element, water molecules can pass through the reverse osmosis membrane more smoothly, while various impurities, ions, bacteria and viruses in the water are intercepted on the other side of the membrane. The pressure provided by the booster pump 23 accelerates the flow rate of water on the surface of the reverse osmosis membrane, and more water can be processed per unit time, which greatly improves the filtration efficiency. Sufficient pressure can also ensure the interception effect of the reverse osmosis membrane on impurities. The stable pressure provided by the booster pump 23 can ensure that the reverse osmosis membrane fully exerts its interception function, so that impurities, heavy metal ions, bacteria and viruses in the water are further intercepted, thereby obtaining purer water.

[0084] In some embodiments of the present application, it further includes: a reflux pump, which is disposed in the third pipeline 6 and is used to drive the medium in the third pipeline 6 to flow back to the second filtering device 3 .

[0085] The reflux pump is arranged in the third pipeline 6, and its main function is to provide power for the medium in the third pipeline 6, drive the water to flow in the third pipeline 6, and enable it to flow back to the second filter device 3. When the water purifier has been stationary for a period of time, in order to improve the water quality, the reflux pump is started. The water that may have been contaminated and contained microorganisms and impurities in the second filter device 3 and related pipelines is sucked and pushed from one end of the third pipeline 6 under the action of the reflux pump, and flows back to the second filter device 3. When the refluxed water passes through the second filter device 3 again, the second filter device 3 can further remove the microorganisms, impurities and odorous substances in the water. Since the reflux pump provides stable power, the water can pass through the second filter device 3 at a certain flow rate and pressure, ensuring the effective interception of various harmful substances by the reverse osmosis membrane. After multiple cycles of filtration, the pollutant content in the water is significantly reduced, and the water quality is significantly improved; at the same time, the circulating flow driven by the reflux pump can reduce the deposition and attachment of microorganisms and impurities on the surface of the second filter device 3. During the circulation of water, a certain flushing effect is produced on the surface of the reverse osmosis membrane, preventing impurities from forming a difficult-to-remove dirt layer on the membrane surface, thereby reducing the degree of membrane contamination and extending the service life of the second filter device 3. This not only reduces the frequency and cost of replacing the filter element, but also improves the overall reliability of the water purifier.

[0086] In some other embodiments of the present application, it further includes: a second one-way valve 53, which is arranged on the third pipeline 6, and is suitable for limiting the one-way flow of the medium in the third pipeline 6 in the direction of the second filter inlet 31.

[0087] The second one-way valve 53 is arranged on the third pipeline 6, and its main function is to limit the one-way flow of the medium in the third pipeline 6 in the direction of the second filter inlet 31. When the reflux pump is started and drives the water to flow in the third pipeline 6, the water can smoothly pass through the second one-way valve 53 and flow in the direction of the second filter inlet 31 to enter the second filter device 3 for re-filtration. When the reflux pump stops working or in other working conditions of the water purifier, the second one-way valve 53 will prevent the water from flowing in the opposite direction and prevent the water from flowing back from the second filter inlet 31 to the third pipeline 6, avoiding the backflow that causes the water that has undergone a certain filtering treatment to contact with the impurities, microorganisms, etc. that have been intercepted on the second filter device 3 again, thereby re-polluting the water quality and affecting the purification effect of the water purifier, ensuring that the water is always circulated and filtered in a predetermined direction, and maintaining the stability and order of the water flow inside the water purifier.

[0088] According to some embodiments of the water purifier assembly 100 of the present application, a wastewater outlet 33 is further provided on the second filter device 3, and the water purifier assembly 100 also includes: a fourth pipeline 34, one end of the fourth pipeline 34 is connected to the wastewater outlet 33, and the fourth pipeline 34 is also provided with a third control valve 341, and the third control valve 341 can selectively control the conduction or disconnection of the fourth pipeline 34.

[0089] One end of the fourth pipeline 34 is connected to the wastewater outlet 33 of the second filtering device 3, and its function is to provide a discharge channel for the wastewater. The third control valve 341 is arranged on the fourth pipeline 34, and can selectively control the conduction or disconnection of the fourth pipeline 34 according to the working state of the water purifier and the preset program. When the water purifier performs filtering work, the third control valve 341 can be opened as needed to discharge the wastewater generated in the reverse osmosis membrane filtering process out of the water purifier through the fourth pipeline 34. When the wastewater does not need to be discharged, the third control valve 341 is opened when the water purifier is not working. 341 can be closed to prevent wastewater from flowing out, avoiding unnecessary waste of water resources. Timely discharge of wastewater can effectively reduce the accumulation of pollutants on the surface of the reverse osmosis membrane, and prevent impurities, ions and other substances in the wastewater from adhering to the surface of the reverse osmosis membrane for a long time to form a layer of dirt, increase the resistance of water passing through the membrane, and reduce the filtration efficiency and desalination rate of the membrane. Timely discharge of wastewater through the fourth pipeline 34 and the third control valve 341 keeps the surface of the reverse osmosis membrane clean, helps maintain its good filtration performance, extends the service life of the reverse osmosis membrane, and reduces the cost of replacing the filter element.

[0090] According to some embodiments of the present application, the water purifier assembly 100 further includes: a first filter shell 7, the first filter device 2 and the third filter device 4 are integrated in the first filter shell 7, and the first filter shell 7 is provided with a first filter inlet 21, a first filter outlet 22, a third filter inlet 41 and a third filter outlet 42.

[0091] The first filter device 2 and the third filter device 4 are integrated in the first filter shell 7, so that the internal structure of the water purifier is significantly simplified. The first filter shell 7 is provided with a corresponding first filter inlet 21, a first filter outlet 22, a third filter inlet 41 and a third filter outlet 42, which clarifies the inlet and outlet paths of the water flow. The multiple filter devices and their related pipelines that originally needed to be connected at different positions can now be concentrated in one shell 30, reducing the length of the pipeline and the connection points, making the overall structure of the water purifier more compact and occupying less space, which is conducive to the miniaturized design of the product and adaptable to different usage scenarios. Since the first filter device 2 and the third filter device 4 are integrated in the same shell 30, the transmission of water between the two filter devices is more direct and smooth. The water that has been preliminarily filtered by the first filter device 2 can quickly enter the third filter device 4 for further deep filtration after passing through the second filter device 3, reducing the energy loss and pressure loss of the water flow during the transmission process.

[0092] According to some embodiments of the water purifier assembly 100 of the present application, the first filter shell 7 is constructed as a cylinder, and a first cavity 71 and a second cavity 72 isolated from each other are arranged in the extension direction of the cylinder, a first filter device 2 is arranged in the first cavity 71, and the first filter inlet 21 and the first filter outlet 22 are connected to the first cavity 71, a third filter device 4 is arranged in the second cavity 72, and the third filter inlet 41 and the third filter outlet 42 are connected to the second cavity 72.

[0093] The first filter housing 7 is constructed as a cylinder, and a first cavity 71 and a second cavity 72 are provided in the extension direction of the cylinder, which are isolated from each other. The partition enables the first filter device 2 and the third filter device 4 to work in relatively independent spaces. The first filter device 2 in the first cavity 71 is mainly responsible for preliminary filtering of raw water, removing larger particulate impurities, suspended matter, etc. in the water. Since the first filter inlet 21 and the first filter outlet 22 are connected to the first cavity 71, the raw water can smoothly enter the first cavity 71 for preliminary filtering, while the third filter device 4 in the second cavity 72 is responsible for deep purification of the water passing through the second filter device 3, further removing micro impurities, bacteria, viruses, heavy metal ions and other harmful substances in the water, and improving the taste. The third filter inlet 41 and the third filter outlet 42 are connected to the second cavity 72, ensuring that the water passing through the second filter device 3 can enter the second cavity 72 for deep filtration, and output the purified water at the same time. This partition design ensures that the functions of the two filtering devices do not interfere with each other, and each can function more efficiently; the first cavity 71 and the second cavity 72 are isolated from each other, effectively preventing the mixing of water at different filtering stages, and avoiding the mixing of water after preliminary filtration with raw water or water after deep filtration, thereby affecting the final water quality. Unfiltered impurities in the raw water may be mixed into the water that has been deeply filtered, resulting in a decrease in water quality. By isolating the first cavity 71 and the second cavity 72, it is ensured that water passes through the first filtering device 2 and the third filtering device 4 in sequence according to the established filtration process, and water at different stages will not mix with each other, thereby ensuring the purity and stability of the water quality and providing safer and more reliable drinking water.

[0094] According to some embodiments of the water purifier assembly 100 of the present application, a first inner cavity 711 and a first outer cavity 712 are formed in the first cavity 71, the first filter device 2 is arranged between the first inner cavity 711 and the first outer cavity 712, the first outer cavity 712 is connected to the first filter inlet 21, and the first inner cavity 711 is connected to the first filter outlet 22; a second inner cavity 721 and a second outer cavity 722 are formed in the second cavity 72, the third filter device 4 is arranged between the second inner cavity 721 and the second outer cavity 722, the second outer cavity 722 is connected to the third filter inlet 41, and the second inner cavity 721 is connected to the third filter outlet 42.

[0095] In the first cavity 71, the first outer cavity 712 is connected to the first filter inlet 21, and the raw water first enters the first outer cavity 712. Since the first filter device 2 is arranged between the first inner cavity 711 and the first outer cavity 712, water needs to pass through the first filter device 2 to enter the first inner cavity 711, and then flow out through the first filter outlet 22, so that the distribution of water flow on the first filter device 2 is more uniform, and the raw water can fully contact the filter material of the first filter device 2, thereby improving the effect of the preliminary filtration, and large particles of impurities, suspended matter, etc. in the water can be more effectively intercepted when passing through the first filter device 2, reducing the possibility of unfiltered water flowing out directly.

[0096] Similarly, in the second cavity 72, the second outer cavity 722 is connected to the third filter inlet 41. After the water filtered by the second filter device 3 enters the second outer cavity 722, it needs to pass through the third filter device 4 to enter the second inner cavity 721, and then flow out through the third filter outlet 42, thereby ensuring that the water is fully filtered by the third filter device 4, so that the third filter device 4 can more effectively remove tiny impurities, bacteria, viruses, heavy metal ions and other harmful substances in the water, further improving the filtering efficiency of the entire water purifier.

[0097] In some embodiments of the present application, the first filter device 2 is constructed as a fiber filter element, and the third filter device 4 is constructed as a mineralized filter element, wherein the fiber filter element removes large particle impurities through the intercepting effect of fibers, wherein the mineralized filter element can not only finely filter the medium flowing out of the second filter device 3 but also supplement minerals to the medium flowing through the mineralized filter element to further improve the taste of water, and the mineralized material can be medical stone, tourmaline, strontium-rich ore, etc.

[0098] According to some embodiments of the present application, the water purifier assembly 100 further includes a second filter housing 8, a second filter device 3 is arranged in the second filter housing 8, and a second filter inlet 31 and a second filter outlet 32 ​​are arranged on the second filter housing 8; a mounting seat 81, and a first mounting groove 811 and a second mounting groove 812 are formed on the mounting seat 81 and are spaced apart in the height direction, and the first filter housing 7 and the second filter housing 8 are detachably connected to the first mounting groove 811 and the second mounting groove 812, respectively.

[0099] A first mounting groove 811 and a second mounting groove 812 are provided on the mounting seat 81, and the first filter housing 7 and the second filter housing 8 are detachably connected to them respectively, so that during the assembly process of the water purifier, the first filter housing 7 and the second filter housing 8 can be accurately installed on the mounting seat 81, and the installation can be completed by simple fixing methods such as snaps, screws, etc., which greatly improves the production efficiency; when the water purifier needs to be maintained or the filter element needs to be replaced, the detachable connection method makes the operation easier. For the filter element in the first filter housing 7 or the second filter housing 8, it is only necessary to loosen the corresponding fixing parts to easily remove the filter housing 30 from the mounting groove, and perform operations such as replacing or cleaning the filter element. After completing the maintenance, the filter housing 30 can be conveniently reinstalled back to the mounting seat 81 to restore the normal use of the water purifier, thereby improving the user experience of the water purifier.

[0100] According to some embodiments of the present application, the water purifier assembly 100 further includes: a water circuit plate 9, which is arranged at the rear end of the mounting seat 81, and the interior of the water circuit plate 9 is formed with a first pipeline 1, a second pipeline 5 and a third pipeline 6, and the surface of the water circuit plate 9 in the thickness direction is formed with a first matching hole 91, a second matching hole 92, a third matching hole 93, a fourth matching hole 94, a fifth matching hole 95 and a sixth matching hole 96 which are respectively connected and matched with the first filter inlet 21, the first filter outlet 22, the second filter inlet 31, the second filter outlet 32 ​​and the third filter inlet 41 and the third filter outlet 42.

[0101] The first pipeline 1, the second pipeline 5 and the third pipeline 6 are formed inside the waterway plate 9, and the originally scattered pipelines are integrated into one plate. The integrated design changes the disorderly distribution of pipelines in the traditional water purifier, making the waterway layout inside the water purifier more regular and orderly. It avoids the different pipelines of the traditional water purifier that may need to be coiled inside the machine and occupy a lot of space. The setting of the waterway plate 9 allows these pipelines to be reasonably planned in the plate, making full use of the space at the rear end of the mounting seat 81, avoiding the waste of space, so that the overall structure of the water purifier is more compact, which is conducive to the miniaturization design of the product and adapting to different usage scenarios; at the same time, the surface of the waterway plate 9 in the thickness direction is provided with holes that are connected and matched with the inlet and outlet of each filter device, such as the first matching hole 91, the second matching hole 92, etc. These holes accurately correspond to the inlet and outlet of the first filter housing 7 and the second filter housing 8, so that the water flow can smoothly flow into or out of the corresponding pipeline from the filter device, further optimizing the connection of the waterway and improving the utilization efficiency of the space.

[0102] The arrangement of the water circuit plate 9 simplifies the pipe connection. The first filter housing 7 and the second filter housing 8 are directly connected to the matching holes on the water circuit plate 9 , reducing the number of intermediate joints and pipe fittings. The first filter outlet 22 of the first filter device 2 is directly connected to the corresponding pipe inside the water circuit plate 9 through the second matching hole 92, without the need for additional complex connecting components. Fewer connection points means lower risk of water leakage. Reducing the connection points can effectively reduce the possibility of water leakage and improve the reliability and stability of the water purifier. The overall structure of the water circuit plate 9 is relatively sealed, and the internal pipes are better protected inside the plate, further reducing the problem of water leakage caused by external factors.

[0103] In some embodiments of the present application, the water circuit plate 9 includes: a first sub-water circuit plate 97 and a second sub-water circuit plate 98, the first sub-water circuit plate 97 is arranged at the rear end of the mounting seat 81, the first sub-water circuit plate 97 is connected to the first filter shell 7 and the second filter shell 8, the first sub-water circuit plate 97 is provided with a first matching hole 91, a second matching hole 92, a third matching hole 93, a fourth matching hole 94, a fifth matching hole 95 and a sixth matching hole 96, and the second sub-water circuit plate 98 is arranged on the side of the first sub-water circuit plate 97 away from the mounting seat 81; wherein a convex portion 981 is formed on the side of the first sub-water circuit plate 97 away from the mounting seat 81 and / or the side of the second sub-water circuit plate 98 facing the mounting seat 81, and the convex portion 981 closes at least part of the space between the first sub-water circuit plate 97 and the second sub-water circuit plate 98 and forms a first pipeline 1, a second pipeline 5 and a third pipeline 6.

[0104] The waterway plate 9 is divided into a first sub-waterway plate 97 and a second sub-waterway plate 98. The first sub-waterway plate 97 is arranged at the rear end of the mounting seat 81 and is responsible for communicating with the first filter housing 7 and the second filter housing 8. The second sub-waterway plate 98 is arranged on the side of the first sub-waterway plate 97 away from the mounting seat 81, and a complete pipeline system is formed by cooperating with the first sub-waterway plate 97. A convex portion 981 is formed on at least one of the side of the first sub-waterway plate 97 away from the mounting seat 81 and the side of the second sub-waterway plate 98 facing the mounting seat 81, and at least part of the space between the two is closed to form a first pipeline 1, a second pipeline 5 and a third pipeline 6. This method of using the convex portion 981 to form the pipeline makes full use of the space between the two sub-waterway plates 9 and avoids occupying additional space. By reasonably designing the shape and position of the convex portion 981, the direction and diameter of the pipeline can be accurately controlled, so that water can flow smoothly in the pipeline, reducing the messy distribution of the pipeline inside the water purifier and improving space utilization. At the same time, the provision of the protrusion 981 also makes the formation of the pipeline simpler and more controllable, and does not require complicated pipeline bending and connection processes during the manufacturing process, thereby reducing the manufacturing difficulty and cost.

[0105] According to the beverage purifier assembly 100 of some embodiments of the present application, the functional module 20 is connected to the outlet of the third filter device 4 , and the functional module 20 is suitable for heating, cooling or ice-making the medium flowing out of the third filter device 4 .

[0106] The functional module 20 is connected to the outlet of the third filter device 4, which means that the deeply purified water will flow into the functional module 20 for further processing. The functional module 20 can heat, cool or ice the water flowing out of the third filter device 4, meeting the diverse drinking water needs in different seasons and scenarios.

[0107] According to some embodiments of the beverage purifier assembly 100 of the present application, the functional module 20 includes: a water tank 201, the water tank 201 is connected to the outlet of the third filter device 4, and the water tank 201 is provided with a first outlet 2011 and a second outlet 2012; a heating module 202, the heating module 202 is connected to the first outlet 2011, and the heating module 202 is suitable for heating and directing the heated medium to the hot water outlet 2021; a cold water tank 203, the cold water tank 203 is connected to the second outlet 2012, a cold water cavity 2031 is formed in the cold water tank 203, and the cold water cavity 2031 is connected to the cold water outlet 2032; a cooling device 204, the cooling device 204 is provided with a cooling cavity 2041 and an ice outlet cavity 2042, the inlet of the cooling cavity 2041 is connected to the cold water cavity 2031 and is used to refrigerate or make ice for water entering the ice making cavity from the cold water cavity 2031.

[0108] The functional module 20 has made a detailed division of labor for water treatment by setting up a water tank 201, a heating module 202, a cold water tank 203 and a cooling device 204, so as to meet various drinking water needs. The water tank 201 is connected to the outlet of the third filter device 4 to first store deeply purified water to provide a stable water source for subsequent processing.

[0109] When hot water is needed, the first outlet 2011 of the water storage tank 201 is connected to the heating module 202, and the heating module 202 can heat the water to a suitable temperature and guide the water to the hot water outlet 2021 to meet the needs of making tea, coffee or drinking hot water; the cooling device 204 meets the needs of ice making and refrigeration. The inlet of the cooling cavity 2041 of the cooling device 204 is connected to the cold water cavity 2031, and the water in the cold water cavity 2031 can be introduced for refrigeration or ice making. The produced ice cubes can be taken out from the ice outlet cavity 2042 to meet the needs of making cold drinks, etc., which greatly improves the experience. When ice water is needed, the second outlet 2012 of the water storage tank 201 is connected to the cold water tank 203, and the cold water cavity 2031 in the cold water tank 203 stores water cooled by the cooling device 204, which can flow out through the cold water outlet 2032.

[0110] According to the water purifier assembly 100 of some embodiments of the present application, the cooling device 204 includes: a cooling inner shell 2043, a cooling cavity 2041 is formed in the cooling inner shell 2043, and a cooling outlet 20431 that can be selectively opened and closed is provided on the cooling inner shell 2043; an evaporator 2044, the evaporator 2044 is arranged in the cooling inner shell 2043, at least part of the evaporator 2044 is in contact with the medium in the cooling inner shell 2043, and the evaporator 2044 is suitable for refrigerating or making ice for the medium in the cooling cavity 2041; a cooling outer shell 2045, the cooling outer shell 2045 is provided with a cooling outlet 20431 that can be selectively opened and closed; an evaporator 2044, the evaporator 2044 is arranged in the cooling inner shell 2043, at least part of the evaporator 2044 is in contact with the medium in the cooling inner shell 2043, and the evaporator 2044 is suitable for refrigerating or making ice for the medium in the cooling cavity 2041; and a cooling outer shell 2045. 45 is arranged on the outer side of the cooling inner shell 2043, a return water chamber 20451 is formed between the cooling outer shell 2045 and the cooling inner shell 2043, the return water chamber 20451 is suitable for collecting the medium exported from the cooling outlet 20431, and a return water port 20452 and an export port 20453 are formed on the cooling outer shell 2045, the return water port 20452 is connected with the cold water chamber 2031, and the export port 20453 is connected with the ice outlet cavity 2042; an ice storage chamber 2046, an ice outlet cavity 2042 is formed in the ice storage chamber 2046, and an ice outlet 402 is arranged in the ice storage chamber 2046.

[0111] In the cooling device 204, the evaporator 2044 is arranged in the cooling inner shell 2043 and at least partially contacts the medium in the cooling inner shell 2043. The evaporator 2044 works through the refrigeration system to absorb the heat of the water in the cooling cavity 2041, so that the temperature of the water is reduced, thereby achieving a refrigeration effect; when the temperature is further reduced to below the freezing point, the water will condense into ice. Due to the direct contact between the evaporator 2044 and the water, heat can be transferred more efficiently, thereby improving the efficiency of refrigeration and ice making.

[0112] The cooling cavity 2041 formed in the cooling inner shell 2043 provides a relatively closed space for water, so that the evaporator 2044 can cool the water more centrally, avoiding the heat loss caused by open cooling, and improving the stability and efficiency of the cooling effect. During the ice-making process, the closed cooling cavity 2041 can ensure that the water is evenly cooled in a low-temperature environment to form ice cubes with better quality. The cooling outlet 20431 that can be opened and closed selectively on the cooling inner shell 2043 provides flexibility for the discharge of cold water after cooling and ice cubes after ice making. When drainage is required, the cooling outlet 20431 can be opened to discharge the cold water in the cooling cavity 2041. After ice making is completed, the cooling outlet 20431 can also be opened to allow the ice cubes to smoothly enter the subsequent ice-discharging process. The return water cavity 20451 formed between the cooling outer shell 2045 and the cooling inner shell 2043 cooperates with the cooling outlet 20431 to collect and guide the return water. The water derived from the cooling outlet 20431 (which can be the condensed water generated during the refrigeration process or the remaining water after ice making, or the cold water after refrigeration or the melted water after ice making is completed) will flow into the return water cavity 20451, and then be connected with the cold water cavity 2031 through the return water port 20452, so that the water can flow back to the cold water tank 203, thereby realizing the recycling of water resources, avoiding the waste of water resources, and ensuring the stable operation of the internal water system of the water purifier.

[0113] The ice outlet cavity 2042 formed inside the ice storage chamber 2046 is connected to the outlet 20453 of the cooling outer shell 2045, so that ice cubes can be smoothly transferred from the cooling device 204 to the ice storage chamber 2046, and ice cubes can be obtained from the ice outlet cavity 2042 for making cold drinks or other purposes.

[0114] According to some embodiments of the water purifier assembly 100 of the present application, a water level monitoring component 2013 is provided in the water tank 201, and the water level monitoring component 2013 is suitable for detecting the water level in the water tank 201; the water purifier assembly 100 also includes: a first solenoid valve 44, the first solenoid valve 44 is arranged between the third filter device 4 and the functional module 20, and the first solenoid valve 44 can selectively control the medium to flow from the third filter device 4 to the functional module 20; wherein the first solenoid valve 44 and the water level monitoring component 2013 are communicatively connected, and the first solenoid valve 44 can selectively control the flow state of the medium from the third filter device 4 to the functional module 20 according to the water level monitoring component 2013 detecting the water level in the water tank 201.

[0115] The water level monitoring component 2013 can detect the water level in the water tank 201 in real time and accurately. When the water level in the water tank 201 drops to the minimum limit, or when the water level in the water tank 201 rises to the maximum limit, the water level monitoring component 2013 will transmit this information to the first solenoid valve 44 that is communicated with it. The first solenoid valve 44 is arranged between the third filter device 4 and the functional module 20. When receiving the low water level signal from the water level monitoring component 2013, the first solenoid valve 44 will open, allowing the water purified by the third filter device 4 to flow into the water tank 201 to replenish the water volume. When the water level rises to a preset high level, the water level monitoring component 2013 sends a signal again, and the first solenoid valve 44 is closed to stop the water supply. By controlling the water level, the water level in the water tank 201 is ensured to always remain within a reasonable range, thereby achieving effective management of water resources, avoiding waste of water resources, and avoiding overfilling of the water tank 201, which would lead to water overflow and waste. At the same time, water level control also helps to save energy. When the water level in the water tank 201 is appropriate, the purification module suspends purification, reducing unnecessary energy consumption.

[0116] According to some embodiments of the present application, the water purifier assembly 100 further includes: a shell 30, a housing 30 having an accommodating chamber 301 formed therein, a first filter device 2, a second filter device 3, a third filter device 4 and a functional module 20 arranged in the accommodating chamber 301; a panel 40, the panel 40 being arranged on the shell 30, and a water outlet 401 and an ice outlet 402 being arranged on the panel 40, wherein the water outlet 401 is selectively connected to the hot water outlet 2021 and the cold water outlet 2032.

[0117] The accommodating cavity 301 formed inside the housing 30 provides a stable installation environment for the first filter device 2, the second filter device 3, the third filter device 4 and the functional module 20. The above internal components may be affected by external collisions, dust, moisture, etc. during operation, and the housing 30 can block external factors, protect the normal operation of the internal components, and extend the service life. The panel 40 is set on the housing 30, and together with the housing 30, it constitutes the appearance of the water purifier. The panel 40 is provided with a water outlet 401 and an ice outlet 402, which improves the convenience of use. The water outlet 401 set on the panel 40 can be selectively connected with the hot water outlet 2021 and the cold water outlet 2032, providing a diversified water collection experience. You can choose to get hot water or cold water by operating the relevant buttons or switches on the panel 40. The setting of the ice outlet 402 further enriches the function of the water purifier, and ice cubes can be conveniently obtained from the ice outlet 402 for making cold drinks or other purposes. These designs on the panel 40 make the operation of the water purifier simpler and more intuitive, without the need for complex operations or finding other equipment, and improve the user experience and satisfaction.

[0118] According to some embodiments of the water purifier assembly 100 of the present application, the leakage prevention device includes: a second solenoid valve 11: the second solenoid valve 11 is arranged on the first pipeline 1, and the second solenoid valve 11 is suitable for controlling the conduction state of the first pipeline 1; a water leakage probe 302, the water leakage probe 302 is arranged in the accommodating cavity 301, the water leakage probe 302 is communicatively connected with the second solenoid valve 11, and the water leakage probe 302 is suitable for detecting whether there is leaked medium in the accommodating cavity 301, wherein the second solenoid valve 11 can selectively control the conduction state of the first pipeline 1 according to the detection state of the water leakage probe 302.

[0119] The water leakage probe 302 is arranged at the bottom of the accommodating chamber 301, and can detect whether there is a water leakage. There are multiple water path components inside the water purifier, such as the first filter device 2, the functional module 20, etc. During long-term use, water leakage may occur due to aging of components, sealing failure, etc. After a water leakage occurs, the water will flow to the bottom of the accommodating chamber 301. At this time, the water leakage probe 302 can be quickly detected. When the water leakage probe 302 detects a water leakage, it will generate an electrical signal to be transmitted to the second solenoid valve 11. The second solenoid valve 11 is arranged on the first pipeline 1. After receiving the electrical signal, it will control the conduction state of the first pipeline 1 according to the signal, and close the first pipeline 1 in time to cut off the water source. This can effectively prevent water from continuing to leak and avoid greater harm caused by leakage, such as damaging other components inside the water purifier, causing the floor to become damp and deformed, causing electrical short circuits and other safety hazards. The water purifier is equipped with electronic or mechanical components that are sensitive to water. The cooperation of the second solenoid valve 11 and the water leakage probe 302 can cut off the water source when leakage occurs, reduce the contact time between water and internal components, and reduce the risk of component damage.

[0120] According to some embodiments of the present application, the water purifier assembly 100 further includes: a home furnishing item, on which a mounting cavity for accommodating the shell 30 is formed.

[0121] It should be noted that the home furnishing item can be a cabinet, a wall, etc. The installation cavity formed on the home furnishing item is used to store the shell 30, so that the water purifier can be embedded in the home environment. By storing the water purifier in the installation cavity of the home furnishing item, it can avoid the water purifier being placed alone and occupying too much space, which can save space and make the spatial layout more regular and orderly.

[0122] According to some embodiments of the beverage purifier assembly 100 of the present application, it also includes: a heat sink 50, which is disposed on the shell 30, and is provided with a heat dissipation outlet open to the installation cavity, and the heat sink 50 is used to discharge the airflow inside the accommodating cavity 301 to the installation cavity; a heat-conducting component 60, at least a portion of the heat-conducting component 60 is accommodated in the accommodating cavity 301, and a heat-conducting channel is formed inside the heat-conducting component 60, one end of the heat-conducting channel is open to the installation cavity, and the other end of the heat-conducting channel is open to the front or side of the shell 30.

[0123] During the operation of the water purifier, the internal heating module 202, refrigeration system and various electronic components will generate heat, and the hot air will be guided from the inside of the water purifier to the installation cavity through the heat sink 50, thereby reducing the temperature in the accommodating cavity 301, ensuring that the internal components work in a suitable temperature environment, and improving the stability and reliability of the operation of the water purifier. The setting of the heat conduction component 60 further optimizes the heat dissipation path. At least part of the heat conduction component 60 is accommodated in the accommodating cavity 301, and one end of the heat conduction channel formed inside is open to the installation cavity, and the other end is open to the front or side of the shell 30, so that heat can be transferred to the outside more quickly through the heat conduction channel. The heat sink 50 discharges the airflow inside the accommodating cavity 301 to the installation cavity, and the heat conduction component 60 also guides the heat to the front or side of the shell 30, avoiding the accumulation of heat inside the water purifier and the home environment, avoiding the accumulation of heat in the installation cavity, affecting the performance and service life of the home parts and the water purifier assembly 100, and may even cause damage to the surrounding items, ensuring that the temperature in the installation cavity is within a reasonable range, protecting the home parts and the surrounding home environment.

[0124] In some embodiments of the present application, it also includes: a first water quality detection component 24, which is arranged between the first filter device 2 and the second filter device 3, and the first water quality detection component 24 is suitable for detecting the water quality of the medium passing through the first filter device 2.

[0125] The first water quality detection element 24 is arranged between the first filter device 2 and the second filter device 3. When the water initially filtered by the first filter device 2 passes through, the first water quality detection element 24 can detect various indicators in the water in real time, and can detect the content of microorganisms in the water. If the number of microorganisms such as bacteria and viruses detected exceeds the normal range, it means that the filtering effect of the first filter device 2 may be reduced, or the pollution degree of the raw water exceeds expectations. At the same time, it can also detect indicators such as the residual amount of particulate impurities in the water and the concentration of some metal ions. Through these detection data, on the one hand, the working status of the first filter device 2 can be fed back in time. If the water quality detection data is found to be abnormal, it can be judged whether the first filter device 2 needs to be cleaned or the filter element replaced, so as to take timely measures to ensure the normal operation of the first filter device 2, and then ensure the stable operation of the subsequent second filter device 3.

[0126] In some other embodiments of the present application, it also includes: a second water quality detection component 43, which is arranged between the third filter device 4 and the functional module 20, and the second water quality detection component 43 is used to detect the water quality of the medium passing through the third filter device 4.

[0127] The second water quality detection component 43 is arranged between the third filter device 4 and the functional module 20, and can accurately detect the water purified by the second filter component and the third filter device 4. By detecting the indicators in the water, such as the microbial content, the heavy metal ion concentration, the pH value, etc., it can be accurately judged whether the filtering effect of the second water quality detection component 43 and the third filter device 4 meets the expectations. If the bacteria content in the water is detected to be excessive, it means that the second water quality detection component 43 and the third filter device 4 may have problems such as filter element blockage or damage, resulting in a decrease in its filtering capacity. If these problems are discovered in time, corresponding measures can be taken, such as replacing the filter element or maintaining the second water quality detection component 43 and the third filter device 4, to ensure that the subsequent outflowing water always meets the safe drinking standards.
