Description

Technical Field

[0001] The utility model relates to the technical field of water supply, and particularly relates to a water purification system. Background Art

[0002] With the continuous development of technology, the requirements for water supply by some functional devices are increasing day by day, such as coffee machines. Under the current technical background, the water purification system faces many challenges when supplying water to some functional devices. Since the functional device requires purified water with a specific TDS (Total Dissolved Solids), in order to obtain water with a specific TDS, it is required that the water purification system can produce two kinds of water with different TDSs, and then mix the two kinds of water with different TDSs through a water mixing component to obtain mixed water with a specific TDS. However, there is a key problem in the current water purification system, that is, the water production part of the two kinds of water with different TDSs and the water mixing component are not independent of each other. This results in large fluctuations in the TDS of the mixed water obtained by mixing the two kinds of water with different TDSs produced due to changes in factors such as pressure and flow rate during the water mixing process, and it is difficult to stably obtain the purified water with the required specific TDS. In order to meet the requirements of the functional device, the component settings have to be adjusted frequently, which not only increases the complexity of the operation but also reduces the work efficiency. In addition, for functional devices with flow restrictions on water supply, such as coffee machines, the flow rate of the purified water with a specific TDS they require is small. Since at least part of the water production water path of the water purification system uses a booster pump to increase the pressure to increase the water production rate of the purified water, due to the current limiting of the purified water outlet, the pressure of the water production water path of the purified water will rise, which will greatly reduce the service life of the booster pump. Therefore, how to solve the problem of large fluctuations in the TDS of the mixed water when the water purification system provides mixed water to some functional devices has become an urgent technical problem to be solved currently.

[0069] The technical solution of the present utility model has the following remarkable beneficial effects:

[0070] 1. In the water purification system of the present application, the purified water filtered and output by the first filtration component can be input into the first water storage chamber through the first water outlet waterway for storage in advance, and the second purified water filtered and output by the second filtration component can be input into the second water storage chamber through the second water outlet waterway for storage; then, when the user needs the mixed water formed by the first purified water and the second purified water, the mixing component can adjust the ratio of the purified water output from the first water storage chamber and the second purified water output from the second water storage chamber and output it to obtain the mixed water with TDS close to or meeting the user's requirements. Since the purified water in the first water storage chamber and the second purified water in the second water storage chamber have been prepared in advance, during the mixing process, there are basically no changes in factors such as pressure and flow rate at the inlet of the mixing component. Therefore, the change and fluctuation of the TDS of the mixed water obtained by mixing the first purified water and the second purified water can be effectively reduced, so that the purified water with the required specific TDS can be obtained relatively stably; in addition, since there are basically no changes in factors such as pressure and flow rate at the inlet of the mixing component, for the mixing component, it is not necessary to frequently adjust the settings of the mixing component, effectively reducing the complexity of the operation of the mixing component and improving the work efficiency.

[0071] 2. Before the water purification system of the present application outputs the mixed water formed by mixing the first purified water and the second purified water, the purified water filtered and output by the first filtration component can be input into the water storage unit through the first water outlet waterway for storage in advance, and the second purified water filtered and output by the second filtration component can be input into the water storage unit through the second water outlet waterway. The amount of the first purified water output from the first filtration component to the water storage unit and the amount of the second purified water output from the second filtration component to the water storage unit can be adjusted by the mixing component, so that the TDS of the mixed water in the water storage unit is close to or meets the mixed water required by the user; then, the mixed water in the water storage unit is directly output for the user to use. Since the first purified water and the second purified water forming the mixed water in the water storage unit can be prepared in advance, when the already prepared mixed water stored in the water storage unit is directly output, the TDS of the output mixed water will not change or fluctuate, and the purified water with the required specific TDS can be prepared relatively stably in advance through the water storage unit.

[0090] In order to solve the problem that the TDS of the mixed water fluctuates greatly when the water purification system provides mixed water, a water purification system is proposed in this application. Figure 1 It is a schematic structural diagram of the water purification system in the first implementation manner in the embodiment of the present utility model, as Figure 1As shown, the water purification system may include: a first filtration component 1; a second filtration component 2. The first filtration component 1 and the second filtration component 2 may be filtration components with different filtration precisions, so that the TDS of the first purified water filtered and output by the first filtration component 1 is different from the TDS of the second purified water filtered and output by the second filtration component 2; a first water outlet waterway 3, the first water outlet waterway 3 can be communicated with the purified water outlet of the first filtration component 1; a first water storage chamber 4 provided on the first water outlet waterway 3, and the first water storage chamber 4 is used to store the first purified water output from the purified water outlet of the first filtration component 1; a second water outlet waterway 5, the second water outlet waterway 5 can be communicated with the purified water outlet of the second filtration component 2; a second water storage chamber 6 provided on the second water outlet waterway 5, and the second water storage chamber 6 is used to store the second purified water output from the purified water outlet of the second filtration component 2; a water mixing component 7, the water mixing component 7 is respectively communicated with the first water storage chamber 4 and the second water storage chamber 6, and the water mixing component 7 is used to adjust the proportion of the first purified water output from the first water storage chamber 4 and the second purified water output from the second water storage chamber 6 and output.

[0091] In the water purification system of the present application, the first purified water filtered and output by the first filtration component 1 can be input into the first water storage chamber 4 through the first water outlet waterway 3 for storage in advance, and the second purified water filtered and output by the second filtration component 2 can be input into the second water storage chamber 6 through the second water outlet waterway 5 for storage; afterwards, when the user needs the mixed water formed by the first purified water and the second purified water, the proportion of the first purified water output from the first water storage chamber 4 and the second purified water output from the second water storage chamber 6 can be adjusted and output through the water mixing component 7 to obtain the mixed water with a TDS close to or meeting the user's requirements. Since the first purified water in the first water storage chamber 4 and the second purified water in the second water storage chamber 6 have been prepared in advance, during the water mixing process, there are basically no changes in factors such as pressure and flow rate at the inlet of the water mixing component 7. Therefore, the change and fluctuation of the TDS of the mixed water obtained by mixing the first purified water and the second purified water can be effectively reduced, so that the purified water with a required specific TDS can be obtained relatively stably; in addition, since there are basically no changes in factors such as pressure and flow rate at the inlet of the water mixing component 7, for the water mixing component 7, it is not necessary to frequently adjust the settings of the water mixing component 7, effectively reducing the complexity of the operation of the water mixing component 7 and improving the work efficiency.

[0092] In order to better understand the water purification system in the present application, the following will further explain and illustrate it. As Figure 1As shown in the figure, the water purification system may include components such as a first filtration component 1, a second filtration component 2, a first water outlet waterway 3, a second water outlet waterway 5, a first water storage chamber 4, a second water storage chamber 6, and a water mixing component 7. Among them, the first filtration component 1 and the second filtration component 2 may be filtration components with different filtration precisions, so that the TDS of the first purified water filtered by the first filtration component 1 is different from the TDS of the second purified water filtered by the second filtration component 2. In order to enable the second filtration component 2 to output second purified water with a lower TDS, the second filtration component 2 may include a reverse osmosis membrane filtration component, so that the second filtration component 2 filters and outputs pure water. When the second filtration component 2 includes a reverse osmosis membrane filtration component, the TDS of the first purified water filtered by the first filtration component 1 is different from the TDS of the pure water filtered by the second filtration component 2.

[0093] The first filtration component 1 may be any filtration component with a filtration precision different from that of the second filtration component 2, and no limitation is imposed on it in this application. As feasible, the first filtration component 1 may include, but is not limited to, one of the following: a nanofiltration membrane filtration component, an ultrafiltration membrane filtration component, a fiber membrane filtration component, a PP cotton filtration component, an activated carbon filtration component, a ceramic filtration component, and so on.

[0094] As feasible, the first filtration component 1 may be a pre-treatment filtration component of existing types on the market. The pre-treatment filtration component generally may include a PP cotton filtration component, an activated carbon filtration component, etc., and is used for preliminary filtration of water to remove larger-sized impurity particles therein. In this embodiment, Figure 3 This is a schematic structural diagram of the water purification system in the third embodiment of the present utility model. As shown in Figure 3 the figure, the inlet of the second filtration component 2 may be connected to the purified water outlet of the first filtration component 1. In this way, the water entering the second filtration component 2 for filtration can first enter the first filtration component 1 for pre-treatment, thereby effectively improving the service life of the second filtration component 2; at the same time, the first filtration component 1 can not only input the first purified water filtered by itself to the first water storage chamber 4, but also input the first purified water filtered by itself to the second filtration component 2.

[0095] As feasible, Figure 11 This is a schematic structural diagram of the water purification system in the ninth embodiment of the present utility model. As shown in Figure 11As shown, the first water outlet waterway 3 can flow through the inlet and the wastewater outlet filtered by the second filtration component 2. This embodiment is particularly applicable to the case where the TDS of the water source is relatively low, and the wastewater discharged from the second filtration component 2 can be fully utilized as the first purified water input into the first water storage chamber 4, thereby achieving the purpose of saving water. In this embodiment, a wastewater ratio unit 18 is provided on the first water outlet waterway 3 downstream of the wastewater outlet filtered by the second filtration component 2. When the water purification system has a return water waterway 14, the wastewater ratio unit 18 can be replaced by a functional valve having a wastewater ratio function and an on-off function.

[0096] As a feasible solution, Figure 2 FIG. is a schematic structural diagram of the water purification system in the second embodiment of the present invention. Figure 4 FIG. is a schematic structural diagram of the water purification system in the fourth embodiment of the present invention, as Figure 2 and Figure 4 shown, the water purification system may include: a booster pump 8, and the booster pump 8 is used to boost the pressure of the second filtration component 2. For example, the booster pump 8 may be located upstream of the second filtration component 2. When the inlet of the second filtration component 2 is communicated with the purified water outlet of the first filtration component 1, the booster pump 8 may be located between the shunt point downstream of the purified water outlet of the first filtration component 1 and the inlet of the second filtration component 2, so as to only boost the pressure of the second filtration component 2; the booster pump 8 may be located upstream of the shunt point downstream of the purified water outlet of the first filtration component 1, and may include upstream of the inlet of the first filtration component 1, so as to boost the pressure of both the first filtration component 1 and the second filtration component 2. For a functional device 100 with a flow restriction on the water supply, such as a coffee machine, the flow rate of the purified water with a specific TDS required by it is small. Since the first purified water in the first water storage chamber 4 and the second purified water in the second water storage chamber 6 have been prepared in advance, during the water mixing process, neither the first filtration component 1 nor the second filtration component 2 needs to be in the water production state. Therefore, there will be no flow restriction of the first purified water or the second purified water outlet, which will cause the pressure of the first purified water production waterway or the second purified water production waterway to rise, and further will not affect the booster pump 8 that plays a boosting role during water production and reduce its service life.

[0097] During water production, at least part of the purified water production waterway of the water purification system will use a booster pump 8 to increase the pressure to increase the production rate of purified water. However, due to the above-mentioned flow restriction of the purified water outlet, the pressure of the purified water production waterway will rise, which will greatly reduce the service life of the booster pump 8.

[0098] As a feasible solution, as Figure 2 and Figure 4As shown, the water purification system may include: a water inlet port for connecting to a water source. The inlet of the first filtration component 1 may communicate with the water inlet port; the inlet of the second filtration component 2 may communicate with the water inlet port. When the inlet of the second filtration component 2 communicates with the purified water outlet of the first filtration component 1, the inlet of the first filtration component 1 communicates with the water inlet port. At the water inlet port, a water inlet valve 16 may be provided to control the on / off between the water inlet port and the water source.

[0099] As an alternative, the water purification system may include: a first water storage tank having a first water storage chamber 4; and / or, a second water storage tank having a second water storage chamber 6. In this embodiment, the first water storage chamber 4 and the second water storage chamber 6 may be formed in the form of water storage tanks.

[0100] In another alternative embodiment, the water purification system may include: a first water storage tank with a separated first water storage chamber 4 and second water storage chamber 6 inside. In this embodiment, not only can the first water storage chamber 4 and the second water storage chamber 6 be formed in the form of water storage tanks, but also the number of water storage tanks can be reduced, thereby reducing the number of components in the water purification system.

[0101] In yet another alternative embodiment, the first filtration component 1 may include a first housing, and the first water storage chamber 4 is located inside the first housing. And / or, the second filtration component 2 may include a second housing, and the second water storage chamber 6 is located inside the second housing. In this way, the second water storage chamber 6 and the first water storage chamber 4 can be formed inside the housing of the filtration component, thereby optimizing and reducing the number of components in the water purification system. For example, the first filtration component 1 and the second filtration component 2 may be in the form of filter elements with housings, and at this time, the second water storage chamber 6 and the first water storage chamber 4 may be arranged inside the housing.

[0102] As an alternative, in order to controllably control whether the first purified water filtered by the first filtration component 1 is input into the first water storage chamber 4, as Figure 2 and Figure 4 shown, a first on / off valve 9 is provided on the first water outlet waterway 3 upstream of the first water storage chamber 4. In order to controllably control whether the second purified water filtered by the second filtration component 2 is input into the second water storage chamber 6, a second on / off valve 10 is provided on the second water outlet waterway 5 upstream of the second water storage chamber 6. Especially when the inlet of the second filtration component 2 communicates with the purified water outlet of the first filtration component 1, it is necessary to control whether the first purified water output from the purified water outlet of the first filtration component 1 is input into the first water storage chamber 4 or forms the second purified water through filtration by the second filtration component 2 and is input into the second water storage chamber 6.

[0103] As Figures 1 to 4As shown, the mixing water assembly 7 is respectively communicated with the first water storage chamber 4 and the second water storage chamber 6. The mixing water assembly 7 is used to adjust the proportion of the first purified water output from the first water storage chamber 4 and the second purified water output from the second water storage chamber 6 and output the mixed water. The water purification system can advance the first purified water filtered and output by the first filtration assembly 1 into the first water storage chamber 4 for storage through the first water outlet waterway 3, and advance the second purified water filtered and output by the second filtration assembly 2 into the second water storage chamber 6 for storage through the second water outlet waterway 5. Since the filtration accuracy and performance of the first filtration assembly 1 and the second filtration assembly 2 are known, therefore, the general TDS value of the first purified water in the first water storage chamber 4 and the general TDS value of the second purified water in the second water storage chamber 6 are known to the water purification system. When the user needs to mix the first purified water and the second purified water to form mixed water with a TDS close to or meeting the user's requirements, the water purification system can adjust the proportion of the first purified water output from the first water storage chamber 4 and the second purified water output from the second water storage chamber 6 through the mixing water assembly 7 and output it to obtain mixed water with a TDS close to or meeting the user's requirements. Since the first purified water in the first water storage chamber 4 and the second purified water in the second water storage chamber 6 have been prepared in advance, during the mixing process, there are basically no changes in factors such as pressure and flow rate at the inlet of the mixing water assembly 7. Therefore, the change and fluctuation of the TDS of the mixed water obtained by mixing the first purified water and the second purified water can be effectively reduced, and thus the purified water with a required specific TDS can be obtained relatively stably.

[0104] In addition, since there are basically no changes in factors such as pressure and flow rate at the inlet of the mixing water assembly 7, for the mixing water assembly 7, it is not necessary to frequently adjust the settings of the mixing water assembly 7, effectively reducing the complexity of the operation of the mixing water assembly 7 and improving the work efficiency.

[0105] As a feasible Figures 5a to 5c is a schematic structural diagram of a feasible implementation manner of the mixing water assembly in the embodiment of the present invention. As Figure 5a shown, the mixing water assembly 7 may include: a first valve 71 with adjustable opening degree located downstream of the outlet of the first water storage chamber 4. By adjusting the flow rate of the first purified water output from the first water storage chamber 4, the proportion of the first purified water output from the first water storage chamber 4 and the second purified water output from the second water storage chamber 6 can be changed, so as to form mixed water with a specific TDS required by the user. In another feasible implementation manner, the mixing water assembly 7 includes: a second valve 72 with adjustable opening degree located downstream of the outlet of the second water storage chamber 6. By adjusting the flow rate of the second purified water output from the second water storage chamber 6, the proportion of the first purified water output from the first water storage chamber 4 and the second purified water output from the second water storage chamber 6 can be changed, so as to form mixed water with a specific TDS required by the user. In yet another feasible implementation manner, as Figure 5bAs shown, the mixing water assembly 7 may include: a first valve 71 with adjustable opening degree downstream of the outlet of the first water storage chamber 4; and a second valve 72 with adjustable opening degree downstream of the outlet of the second water storage chamber 6. By simultaneously adjusting the first purified water flow rate output from the first water storage chamber 4 and the second purified water flow rate output from the second water storage chamber 6, the ratio of the first purified water output from the first water storage chamber 4 and the second purified water output from the second water storage chamber 6 can be changed, so as to form mixed water with a specific TDS required by the user. In this embodiment, the TDS range of the mixed water that can be formed is wider.

[0106] In other feasible embodiments, such as Figure 5c As shown, the mixing water assembly 7 may include: a regulating valve 73, which has a first inlet, a second inlet and an outlet. The first inlet is communicated with the first water storage chamber 4, and the second inlet is communicated with the second water storage chamber 6. Through the regulating valve 73, the first purified water flow rate output from the first water storage chamber 4 and the second purified water flow rate output from the second water storage chamber 6 can be directly adjusted, so as to change the ratio of the first purified water output from the first water storage chamber 4 and the second purified water output from the second water storage chamber 6, so as to form mixed water with a specific TDS required by the user.

[0107] As feasible, such as Figure 2 and Figure 4 As shown, the water purification system may include: at least one post-filter assembly 15. As feasible, a post-filter assembly 15 is arranged on the first water outlet waterway 3, and the post-filter assembly 15 is located upstream of the first water storage chamber 4. The post-filter assembly 15 is used for post-filtering the first purified water filtered by the first filter assembly 1, so as to remove impurities and peculiar smells in the water and improve the taste of the first purified water. Further, the post-filter assembly 15 includes a third housing, and the first water storage chamber 4 is located within the third housing. As feasible, a post-filter assembly 15 is arranged on the second water outlet waterway 5, and the post-filter assembly 15 is located upstream of the second water storage chamber 6. The post-filter assembly 15 is used for post-filtering the second purified water filtered by the second filter assembly 2, so as to remove impurities and peculiar smells in the water and improve the taste of the second purified water. Further, the post-filter assembly 15 includes a third housing, and the second water storage chamber 6 is located within the third housing. By the above method, the number of components in the water purification system can be optimized and reduced.

[0108] As feasible, such as Figure 2 and Figure 4 As shown, the water purification system may include: a TDS detection component 11, which is used for detecting the TDS of the mixed water formed after the first purified water output from the first water storage chamber 4 and the second purified water output from the second water storage chamber 6 downstream of the mixing water assembly 7 are mixed. By the above method, it can be known what the actual TDS value of the mixed water is under actual measurement, so as to prepare for further precise adjustment of the mixing water assembly 7.

[0109] Further, as Figure 2 and Figure 4 shown, the water purification system may further include: a mixing water channel 12, and the mixing water channel 12 is communicated with the outlet of the mixing component 7. The mixing water channel 12 may converge and mix the first purified water and the second purified water respectively output by the mixing component 7, or may receive the mixed water output by the mixing component 7. The TDS detection component 11 may be disposed on the mixing water channel 12. The outlet of the mixing water channel 12 may be used to communicate with the inlet of the functional device 100. The functional device 100 is a type of device that requires purified water with a specific TDS. For example, a coffee machine, etc. The water purification system supplies water to the functional device 100. Especially for a coffee machine, different TDS values of the input purified water will affect the taste of the brewed coffee. For example, the taste of coffee brewed with purified water with a very low TDS, such as pure water, is completely different from that of coffee brewed with purified water with a high TDS value after simple filtration. Therefore, it is necessary to control the TDS value of the purified water for brewing coffee and make the taste of the coffee brewed with the purified water meet the user's requirements. Therefore, it is necessary to produce the mixed water after mixing the second purified water and the first purified water, and the mixed water can meet the above two requirements.

[0110] In order to enable the first purified water in the first water storage chamber 4 and the second purified water in the second water storage chamber 6 to be mixed and output or separately output under a stable and controllable flow rate, as a feasible solution, as Figure 2 and Figure 4 shown, the water purification system may further include: a water pump 13, and the water pump 13 is disposed on the mixing water channel 12.

[0111] In order to more precisely adjust the TDS of the mixed water, the water purification system may include: a control unit, and the control unit is electrically connected to the TDS detection component 11 and the mixing component 7. The control unit is used to control the mixing component 7 according to the TDS of the mixed water detected by the TDS detection component 11, so as to adjust the ratio of the first purified water output by the first water storage chamber 4 and the second purified water output by the second water storage chamber 6, so that the TDS of the mixed water is closer to or equal to the target TDS value required by the water purification system.

[0112] As a feasible solution, as Figure 2 and Figure 4As shown, the water purification system may include: a return water waterway 14, one end of the return water waterway 14 is communicated with the second water storage chamber 6, and the other end of the return water waterway 14 is communicated with the inlet of the second filtration assembly 2 or upstream thereof; a booster pump 8 can drive the second purified water in the second water storage chamber 6 to flow back to the second filtration assembly 2. A one-way valve that can be conducted from the second water storage chamber 6 to the inlet direction of the second filtration assembly 2 is arranged on the return water waterway 14. Through the return water waterway 14, the second purified water in the second water storage chamber 6 can be used to flush the second filtration assembly 2, and the raw water remaining in the second filtration assembly 2 can also be replaced by the second purified water in the second water storage chamber 6, so that the TDS of the second purified water output at the beginning of the first use after the water purification system has been unused for a long time is reduced, preventing the TDS of the second purified water output at the beginning of the first use from being too high due to the raw water slowly permeating through the filter membrane.

[0113] In this application, a control process of the above water purification system is also proposed, which may include the following steps:

[0114] S101: Store the first purified water with the first TDS value filtered by the first filtration assembly 1 into the first water storage chamber 4.

[0115] S102: Store the second purified water with the second TDS value filtered by the second filtration assembly 2 into the second water storage chamber 6.

[0116] In this step, step S101 and step S102 can be executed synchronously or separately.

[0117] S103: Output the first purified water in the first water storage chamber 4 and the second purified water in the second water storage chamber 6 according to a preset ratio to form purified water with a third TDS value. The third TDS value is between the first TDS value and the second TDS value.

[0118] In the above steps, after executing step S101 and step S102, step S103 is executed.

[0119] In the above steps, the preset ratio can be determined according to the third TDS value, the first TDS value, and the second TDS value. Among them, the preset ratio may include one of the following: the ratio of the flow rate of the first purified water output from the first water storage chamber 4 to the flow rate of the second purified water output from the second water storage chamber 6, the ratio of the total amount of the first purified water output from the first water storage chamber 4 to the total amount of the second purified water output from the second water storage chamber 6, and the ratio of the output time of the first purified water from the first water storage chamber 4 to the output time of the second purified water from the second water storage chamber 6. In the above manner, the preset ratio is preferably the ratio of the flow rate of the first purified water output from the first water storage chamber 4 to the flow rate of the second purified water output from the second water storage chamber 6. In this way, the purified water output can always be maintained at the third TDS value.

[0120] In this control method, the first filtering component 1 and the second filtering component 2 are filtering components with different filtering precisions, so that the TDS of the first purified water filtered and output by the first filtering component 1 is different from the TDS of the second purified water filtered and output by the second filtering component 2.

[0121] As a feasible solution, in step S101, the first purified water with the first TDS value formed by filtering through the first filtering component 1 is stored in the first water storage chamber 4. Specifically, it may include: storing the first purified water with the first TDS value that has been filtered through the first filtering component 1, then input to the second filtering component 2, and discharged from the wastewater outlet of the second filtering component 2 into the first water storage chamber 4. Through this step, the water entering the second filtering component 2 for filtering can first enter the first filtering component 1 for pretreatment, thereby effectively improving the service life of the second filtering component 2; at the same time, the wastewater discharged from the wastewater outlet during the filtering of the second filtering component 2 can also be fully utilized and stored in the first water storage chamber 4 as purified water for use, thereby achieving the purpose of saving water.

[0122] In this application, a water purification system is also proposed. Figure 6 It is a schematic structural diagram of the water purification system in the fifth implementation manner in the embodiments of the present invention. As Figure 6 shown, the water purification system may include: a first filtering component 1; a second filtering component 2, where the first filtering component 1 and the second filtering component 2 are filtering components with different filtering precisions, so that the TDS of the first purified water filtered and output by the first filtering component 1 is different from the TDS of the second purified water filtered and output by the second filtering component 2; a first water outlet waterway 3, the first water outlet waterway 3 can be connected to the purified water outlet of the first filtering component 1; a second water outlet waterway 5, the second water outlet waterway 5 can be connected to the purified water outlet of the second filtering component 2; a water storage unit 17 provided on the first water outlet waterway 3 and the second water outlet waterway 5, the water storage unit 17 is used to store the first purified water output from the purified water outlet of the first filtering component 1 and the second purified water output from the purified water outlet of the second filtering component 2 respectively; a water mixing component 7, the water mixing component 7 is used to adjust the amount of the first purified water output from the first filtering component 1 to the water storage unit 17 and the amount of the second purified water output from the second filtering component 2 to the water storage unit 17.

[0123] Before the water purification system in this application outputs the mixed water formed by mixing the first purified water and the second purified water, the first purified water filtered and output by the first filtering component 1 can be input into the water storage unit 17 through the first water outlet waterway 3 for storage in advance, and the second purified water filtered and output by the second filtering component 2 can be input into the water storage unit 17 through the second water outlet waterway 5. The amount of the first purified water output from the first filtering component 1 to the water storage unit 17 and the amount of the second purified water output from the second filtering component 2 to the water storage unit 17 can be adjusted by the mixing component 7, so that the TDS of the mixed water in the water storage unit 17 is close to or meets the mixed water required by the user; then, the mixed water in the water storage unit 17 is directly output for the user to use. Since the first purified water and the second purified water forming the mixed water in the water storage unit 17 can be prepared in advance, when the stored and already prepared mixed water is directly output from the water storage unit 17, the TDS of the output mixed water will not change or fluctuate, and the water storage unit 17 can stably prepare the purified water with the required specific TDS in advance.

[0124] As feasible, the water storage unit 17 can be any container capable of storing water, such as a water storage tank, and no limitation is imposed on it in this application.

[0125] The first filtering component 1 and the second filtering component 2 in this embodiment can be the same as the first filtering component 1 and the second filtering component 2 in the above embodiment, and will not be elaborated here.

[0126] As feasible, Figure 8 This is a schematic structural diagram of the water purification system in the seventh embodiment of the present invention. As Figure 8 shown, the inlet of the second filtering component 2 can be communicated with the purified water outlet of the first filtering component 1. This embodiment can have the same connection method as the above embodiment, and will not be elaborated here.

[0127] As feasible, Figure 12 This is a schematic structural diagram of the water purification system in the tenth embodiment of the present invention. As Figure 12 shown, the first water outlet waterway 3 can flow through the inlet and the wastewater outlet of the second filtering component 2 for filtration. This embodiment is particularly applicable to the case where the TDS of the water source is relatively low, and the wastewater discharged from the second filtering component 2 can be fully utilized as the first purified water input into the first water storage chamber 4, so as to achieve the purpose of saving water. In this embodiment, a wastewater ratio unit 18 is provided on the first water outlet waterway 3 downstream of the wastewater outlet of the second filtering component 2 for filtration. When the water purification system has a return water waterway 14, the wastewater ratio unit 18 can be replaced by a function valve with a wastewater ratio function and a on-off function.

[0128] The inlets of the water mixing assembly 7 are respectively connected to the first water outlet waterway 3 and the second water outlet waterway 5, and the outlet of the water mixing assembly 7 is connected to the water storage unit 17. The water mixing assembly 7 is used to adjust the first net water volume output from the first filtration assembly 1 to the water storage unit 17 and the second net water volume output from the second filtration assembly 2 to the water storage unit 17. Here, the water mixing assembly 7 can be used to adjust the ratio between the total first net water volume output from the first filtration assembly 1 to the water storage unit 17 and the total second net water volume output from the second filtration assembly 2 to the water storage unit 17, can also adjust the ratio between the first net water flow rate output from the first filtration assembly 1 to the water storage unit 17 and the second net water flow rate output from the second filtration assembly 2 to the water storage unit 17, and can also adjust the ratio between the time when the first filtration assembly 1 outputs the first net water to the water storage unit 17 and the time when the second filtration assembly 2 outputs the second net water to the water storage unit 17. Through the above various methods, it is possible to achieve the mixed water in the water storage unit 17 with the TDS close to or meeting the user's requirements. Since the filtration accuracies and performances of the first filtration assembly 1 and the second filtration assembly 2 are known, the approximate TDS value of the first net water output from the first filtration assembly 1 and the approximate TDS value of the second net water output from the second filtration assembly 2 are known to the water purification system. When the user needs the first net water and the second net water to be mixed to form mixed water with the TDS close to or meeting the user's requirements, the water purification system can adjust the first net water volume output from the first filtration assembly 1 to the water storage unit 17 and the second net water volume output from the second filtration assembly 2 through the water mixing assembly 7, so as to obtain mixed water with the TDS close to or meeting the user's requirements in the water storage unit 17. Since the first net water in the first water storage chamber 4 and the second net water in the second water storage chamber 6 have been prepared in advance, when the water storage unit 17 directly outputs the stored and already prepared mixed water, the TDS of the output mixed water will not change or fluctuate, and the water purification with the required specific TDS can be prepared relatively stably in advance through the water storage unit 17.

[0129] As feasible, the output of the first net water from the first filtration assembly 1 to the water storage unit 17 and the output of the second net water from the second filtration assembly 2 to the water storage unit 17 can be carried out synchronously or separately. During the whole process, the water mixing assembly 7 only needs to be able to adjust the first net water volume output from the first filtration assembly 1 to the water storage unit 17 and the second net water volume output from the second filtration assembly 2 to the water storage unit 17.

By the regulating valve 73, the first purified water flow output by the first filtering assembly 1 and the second purified water flow output by the second filtering assembly 2 can be directly adjusted, so as to change the ratio of the first purified water output by the first filtering assembly 1 and the second purified water output by the second filtering assembly 2, thereby forming mixed water with a specific TDS required by the user.

[0132] In yet another embodiment, as Figure 10b shown, the mixing water assembly 7 may include: a first on-off valve 9 arranged on the first water outlet waterway 3; a second on-off valve 10 arranged on the second water outlet waterway 5.

As feasible, a post-filtering assembly 15 is arranged on the second water outlet waterway 5, the post-filtering assembly 15 is located upstream of the water storage unit 17, and the post-filtering assembly 15 is used for post-filtering the second purified water filtered by the second filtering assembly 2, so as to remove impurities and peculiar smells in the water and improve the taste of the second purified water.

[0134] As feasible, such as Figure 7 and Figure 9 As shown, the water purification system may include: a water pump 13, and the inlet of the water pump 13 is communicated with the outlet of the water storage unit 17. In this way, the mixed water in the water storage unit 17 can be output at a stable and controllable flow rate.

[0135] As feasible, such as Figure 7 and Figure 9 As shown, the water purification system may include: a TDS detection component 11 for detecting the TDS of the water in the water storage unit 17. Through the above method, it can be known what the actual TDS value of the mixed water in the water storage unit 17 is under actual measurement, so as to prepare for the further precise adjustment of the mixed water component 7.

The control unit is used to control the mixed water component 7 according to the TDS of the water in the water storage unit 17 detected by the TDS detection component 11, so as to adjust the first purified water volume output by the first water storage chamber 4 and the second purified water volume output by the second water storage chamber 6, so that the TDS of the mixed water in the water storage unit 17 is closer to or equal to the target TDS value required by the water purification system.

[0138] As feasible, such as Figure 7 and Figure 9As shown, the water purification system may include: a return water waterway 14, one end of the return water waterway 14 is communicated with the water storage unit 17, and the other end of the return water waterway 14 is communicated with the inlet of the second filtration component 2 or upstream thereof; the booster pump 8 can drive the water in the water storage unit 17 to flow back to the second filtration component 2. A one-way valve that can be conducted from the water storage unit 17 to the inlet direction of the second filtration component 2 is arranged on the return water waterway 14.

Through the return water waterway 14, the second purified water in the water storage unit 17 can be used to flush the second filtration component 2, or the second purified water in the water storage unit 17 can be used to replace the raw water remaining in the second filtration component 2, so that the TDS of the second purified water output at the beginning of the first use after the water purification system has been unused for a long time is reduced, preventing the TDS of the second purified water output at the beginning of the first use from being too high due to the slow penetration of the raw water through the filter membrane.

[0139] In this application, a control process of the above water purification system is also proposed, which may include the following steps:

[0140] S201: Input the first purified water with the first TDS value filtered by the first filtration component 1 into the water storage unit 17.

[0141] S202: Input the second purified water with the second TDS value filtered by the second filtration component 2 into the water storage unit 17.

[0142] In this step, step S201 and step S202 can be executed synchronously or separately.
