Description

Technical Field

[0002] The abundance of living materials has prompted people to think about healthy drinking water. Water purifiers are increasingly accepted and recognized by people because they can provide healthy drinking water. However, the reverse osmosis membrane filtration technology used by water purifiers will filter out all substances in the water. Pure water without any beneficial elements is not healthy water in a certain sense and does not meet the latest concept of healthy water.

[0003] At present, the existing technology increases the beneficial mineral elements in water by adding mineral concentrates or using mineralized filters. Mineralized concentrates are generally chemically extracted and concentrated, which is not suitable for long-term drinking. Therefore, the water purification industry often uses mineralized filters to add beneficial substances. However, the raw materials of safe mineralized filters come from ores. The amount of mineral precipitation in ores is limited and the concentration is difficult to control and adjust. In order to achieve the required mineral content, the amount of filter material added to the mineralized filter is generally large, which will increase the price cost, and the concentration still cannot be adjusted according to demand. Therefore, there is currently a lack of a technology that can regulate the mineral content to meet the requirements while controlling the cost. Summary of the invention

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0029] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, although the embodiment may not be clearly recorded in the following text.

In addition, features described in some examples may be combined in other examples.

[0031] See also Figure 1 , Figure 1 It is a schematic diagram of the structure of a mineralized adjustable water purification system provided in an embodiment of the present application. In the embodiment of the present application, the system includes a filter element assembly, an air intake assembly 4, a mineralized filter element 14 and a rear carbon filter element 10 respectively arranged on a fluid pipeline, the inlet of the filter element assembly is connected to the system water inlet 1, the outlet of the filter element assembly is connected to the inlet of the mineralized filter element 14 through the first fluid control assembly 13, the outlet of the filter element assembly is also connected to the inlet of the rear carbon filter element 10 through the second fluid control assembly 9, the outlets of the mineralized filter element 14 and the rear carbon filter element 10 are both connected to the system water outlet 11, the filter element assembly is used to purify and filter the raw water entering the system water inlet 1, the air intake assembly 4 is used to introduce bubbles into the fluid pipeline so that the fluid entering the mineralized filter element 14 is microbubble water, and the first fluid control assembly 13 and the second fluid control assembly 9 are both used to control the flow resistance of the fluid in the fluid pipeline.

[0032] In the embodiment of this specification, in order to purify the water quality, the water purification system needs to first filter the raw water introduced into the system water inlet 1 through the filter element assembly, and then add minerals to the filtered water according to actual needs. The filter element assembly can be composed of one or more different filter elements connected in sequence, and the filter element can include a pretreatment filter element, a membrane filter element, a KDF filter element, a softening filter element, etc. Among them, the pretreatment filter element is mainly used to remove large particles of impurities in the water, such as sediment, rust, suspended matter, etc., and adsorb residual chlorine, odor, color, and some organic matter and chemical pollutants in the water. The membrane filter element is mainly used to filter out smaller particles, bacteria, viruses, certain chemicals and even minerals. When equipped with a reverse osmosis membrane, it can also effectively remove soluble solids in the water, including various salts. The kinetic degradation flow (KDF) filter element is mainly used to remove heavy metals (such as lead and mercury) in water and inhibit bacterial growth. The softening filter element is mainly used to remove hardness minerals (calcium and magnesium) in water to prevent scale formation.

[0033] The air intake assembly 4 can be composed of a device such as a booster pump or an air intake pump that can pass bubbles into the liquid in the fluid pipeline, which can mix bubbles into the fluid to form a large amount of microbubble water, and the microbubble water contains millions of nano- and micro-level bubbles. After the microbubble water passes through the mineralized filter element 14, the ultra-high mass transfer characteristics of the bubbles themselves and the huge energy and free radicals generated by the rupture can accelerate the removal of the filter material minerals in the mineralized filter element 14, thereby increasing the concentration of the fluid after passing through the mineralized filter element 14. In this way, it is not necessary to increase the amount of filter material added in the mineralized filter element 14 to ensure the concentration. The concentration requirements can be met by using an ordinary mineralized filter element 14, and the air intake assembly 4 can still be reused after the mineralized filter element 14 is replaced, and cost control is achieved under the premise of ensuring the concentration. In addition, the air intake assembly 4 is mainly used to generate microbubble water to accelerate the removal of minerals in the mineralized filter element 14. Therefore, as long as it can be ensured that the fluid in the fluid pipeline has formed microbubble water before entering the mineralized filter element 14, its specific installation position in the system can be adjusted according to actual conditions. For example, it can be installed at the outlet position of the filter element assembly, so that both the fluid to the rear carbon filter element 10 and the fluid to the mineralized filter element 14 are microbubble water. It can also be specially installed at the inlet position of the mineralized filter element 14, so that only the fluid to the mineralized filter element 14 is microbubble water. Other implementation methods are also possible.

[0034] Each fluid control component is arranged at a different position of the system to control the flow of different fluid pipeline positions in the system, that is, when the fluid control component is turned on, the fluid can pass through the fluid control component, and when the fluid control component is closed, the fluid will be blocked and cannot pass through the fluid control component. The fluid control component can specifically use a control valve, a control pump, etc. The control valve can use an electrically controlled valve such as a solenoid valve, or a manually controlled valve such as a ball valve and a stop valve. The control pump can be a water pump, a metering pump, a gear pump, etc. When a control pump is selected as a fluid control component, the control pump will be disconnected when it is not working, thereby achieving the closing effect of the valve. When a control pump is selected, the flow rate of the fluid in the pipeline can also be controlled. According to different actual designs, different fluid control components can specifically use different structures. For example, in the embodiment of the present application, the first fluid control component 13 uses a control pump, and the second fluid control component 9 uses a control valve. In such as Figure 2 In other embodiments shown, both the first fluid control component 13 and the second fluid control component 9 use control pumps. When both use control pumps, the concentration range of the water after the mineralization concentration is mixed is larger, and stepless regulation can be basically achieved. In addition, in other possible implementations, control valves can also be used.

[0035] In addition to the mineralized filter element 14, a post-carbon filter element 10, that is, a post-activated carbon filter element, is also arranged in parallel in the pipeline. The post-carbon filter element 10 can further absorb the remaining odor in the water. The post-carbon filter element 10 can specifically be a carbon rod filter element, a wet filter element, etc. The staff can achieve different pipeline access conditions by controlling the first fluid control component 13, the second fluid control component 9 and the air intake component 4 in the system, and then control the concentration of pure water output from the system outlet 11 through different pipeline access conditions. Specifically, at least the following five mineral concentration conditions can be achieved:

[0036] No concentration: the air intake assembly 4 does not work, the first fluid control assembly 13 does not work, the second fluid control assembly 9 works, and the filtered water will directly pass through the rear carbon filter element 10, so that the outlet water does not contain any added minerals.

[0037] Low concentration: the air intake component 4 does not work, the first fluid control component 13 works, the second fluid control component 9 works, and the filtered water passes through the carbon filter element 10 and the mineralization filter element 14 to mix the water, so that the outlet water contains a lower concentration of minerals.

[0038] Medium concentration: the air intake component 4 does not work, the first fluid control component 13 works, the second fluid control component 9 does not work, and the filtered water passes through the mineralization filter element 14, so that the outlet water contains medium concentration of minerals.

[0039] High concentration: the air intake component 4 works, the first fluid control component 13 works, the second fluid control component 9 works, the filtered water passes through the rear carbon filter element 10 and the mineralized filter element 14 to mix with water, and there is a micro-bubble water effect, so that the output water contains a high concentration of minerals.

[0040] Ultra-high concentration: the air intake component 4 works, the first fluid control component 13 works, the second fluid control component 9 does not work, the filtered water passes through the mineralization filter element 14, and there is a micro-bubble water effect, so that the output water contains ultra-high concentration of minerals.

[0041] Through the above method, users can adjust the mineral concentration of the output water according to their own needs, and even if the user needs high-concentration water, it can effectively ensure that the output water concentration meets the requirements.

[0042] In addition, the mineral concentration of the outlet water can be estimated. There are many ways to estimate it according to different situations and needs. As an example, assuming that the outlet flow rate of the control pump is L1, the outlet flow rate of the filter element assembly is L, and the precipitation concentration of the microbubble water after passing through the mineralization filter element is determined to be M by pre-testing, the mineral concentration of the outlet water can be determined according to P=M*L1 / L. In other possible implementations, a concentration detection probe can also be directly set to detect the outlet water concentration.

[0043] In one embodiment, the filter element assembly includes a pretreatment filter element 2 and a membrane filter element 7, the inlet of the pretreatment filter element 2 is connected to the system water inlet 1, the outlet of the pretreatment filter element 2 is connected to the inlet of the membrane filter element 7 through the third fluid control component 3, the first outlet of the membrane filter element 7 is connected to the inlet of the mineralization filter element 14 through the first fluid control component 13, and the first outlet of the membrane filter element 7 is also connected to the inlet of the post-carbon filter element 10 through the second fluid control component 9.

[0044] In the embodiment of this specification, the filter element assembly will be composed of a pre-treatment filter element 2 and a membrane filter element 7. In order to better control the fluid entering the system, a third fluid control assembly 3 is also provided between the pre-treatment filter element 2 and the membrane filter element 7. After the raw water is filtered by the pre-treatment filter element 2, the third fluid control assembly 13 needs to be opened to pass through the membrane filter element 7 and flow out from the first outlet of the membrane filter element 7. The third fluid control assembly 3 is preferably a control valve. Figure 2 As shown, in other embodiments, a flow meter can also be set at the outlet of the membrane filter element 7, and the flow meter is used to detect the water flow rate of the membrane filtration, so as to judge whether the state of the membrane filter element 7 is just right and whether the filter element needs to be replaced.

[0045] In addition, if one of the first fluid control component 13 and the second fluid control component 9 is a control pump, the setting should be adjusted so that the water outlet flow rate of the control pump is not higher than the water outlet flow rate of the membrane filter element 7, so that part of the fluid can enter the filter element where the control valve is located, so that the system can generate mixed water of the post-carbon filter element 10 and the mineralized filter element 14.

[0046] In one embodiment, a pressure reducing valve 5 and a boosting pump 6 are sequentially arranged between the pretreatment filter element 2 and the membrane filter element 7 , and the connection between the air intake assembly 4 and the fluid pipeline is located between the pressure reducing valve 5 and the boosting pump 6 .

[0047] In the embodiment of the present specification, when the microbubble water generated by the air intake component 4 can pass through the rear carbon filter element 10 and the mineralization filter element 14 at the same time, the air intake component 4 can be directly arranged between the pretreatment filter element 2 and the membrane filter element 7, so that the fluid flowing out of the membrane filter element 7 is all microbubble water. At the same time, in order to make the microbubble water generation effect better, a pressure reducing valve and a booster pump are respectively arranged at both ends of the air intake component 4. Before the fluid reaches the position of the air intake component 4, it will be decompressed by the pressure reducing valve, and the flow rate will be reduced, so as to better mix with the bubbles generated by the air intake component 4. After mixing, the microbubble water is restored to a normal flow rate by the boosting of the booster pump.

[0048] In one embodiment, the system further includes a first check valve, the air intake assembly 4 is connected to the outlet of the membrane filter element 7 via the first check valve, and the first check valve is used to prevent the backflow of pure water at the water outlet 11 of the system.

[0049] In the embodiment of this specification, when mineral water is produced according to the concentration, if there is a control pump, the remaining water after the extraction work of the control pump will flow back to the front of the pump. In order to avoid the reflux of the pure water finally generated, a first check valve is set at the outlet position of the membrane filter element 7, and the first check valve can be a high-pressure check valve. After normal water production, the pressure of the water outlet will not be higher than the starting pressure of the first check valve, so the pure water at the system outlet 11 will not flow back.

[0050] In one embodiment, the second outlet of the membrane filter element 7 is connected to the wastewater outlet through the fourth fluid control component 8.

[0051] In the embodiment of the present specification, the membrane filter element 7 has two outlets, and the fluid after membrane filtration will flow out through the first outlet, and then pass through the post-carbon filter element 10 and / or the mineralized filter element 14 to generate pure water. The part rich in various impurities left after filtration will flow out from the second outlet as waste water, and under the control of the fourth fluid control component 8, it will be discharged from the waste water outlet.

[0052] In one embodiment, the air intake assembly 4 includes an air intake pump and a second check valve 12 , and the air intake pump is connected to the fluid pipeline through the second check valve 12 .

[0053] In the embodiment of the present specification, the air intake component 4 can specifically be composed of an air intake pump and a second check valve 12. The second check valve 12 can block flow in one direction to prevent the fluid in the fluid pipeline from entering the air intake pump, but allows the gas generated by the air intake pump to enter the fluid pipeline through the second check valve 12.

[0054] In one possible implementation manner, a detection probe 15 is further provided between the outlet of the mineralization filter element 14 and the system water outlet 11 , and the detection probe 15 is used to detect the dissolved solid content in the fluid pipeline.

[0055] In the embodiment of the present specification, a detection probe 15 can also be directly set on the fluid pipeline of the system to detect the mineral concentration of the fluid in the fluid pipeline through the detection probe 15. The detection probe 15 can be a total dissolved solids probe (Total Dissolved Solids, TDS), a conductivity probe, a pH probe, etc. According to different actual needs, the detection probe 15 can be directly set near the water outlet 11 of the system to directly detect the concentration of pure water, or the detection probe 15 can be set near the outlet of the mineralized filter element 14, so that what is detected is the concentration of the fluid passing through the mineralized filter element 14, rather than the concentration after mixing with the fluid of the post-carbon filter element 10.

[0056] As an example, assume that the first fluid control component 13 and the second fluid control component 9 are both control pumps, one with a working flow rate of L1 and the other with a working flow rate of L2. Figure 2 As shown, it is arranged on the branch of the mineralizing filter element 14, and the precipitated mineralization concentration is detected to be T1. Since the mineralization concentration of the water discharged from the rear carbon filter element 10 can be ignored, the final concentration T of the mixed mineralized water is: T=(L1*T1) / (L1+L2).

[0057] In one possible implementation manner, a detection switch 16 is further provided at the entrance of the system water outlet 11 .

[0058] In the embodiment of this specification, a detection switch 16 can be set near the system water outlet 11. The detection switch 16 can be specifically set to different switches according to different needs, such as a high-pressure switch, a low-pressure switch, a Hall switch, etc. The high-pressure switch is used to prevent equipment damage or safety accidents caused by excessive pressure. The low-pressure switch is used to ensure that there is sufficient water supply to prevent each control pump from idling and being damaged in a waterless state. The Hall switch is used to measure the water flow rate passing through, so as to track the use of the filter element and predict the replacement time.

[0059] The following will be combined with the attached Figure 3 , the control method of the mineralized adjustable water purification system provided in the embodiment of the present application is introduced in detail. It should be noted that the attached Figure 3 The control method of the water purification system with adjustable mineralization shown is applied to this application Figure 1 or Figure 2 For the sake of convenience, only the parts related to the embodiments of the present application are shown in the system of the embodiment shown in the figure. For the specific technical details not disclosed, please refer to the present application. Figure 1 or Figure 2 The embodiment shown.

[0060] See also Figure 3 , Figure 3 Schematic diagram of a control method of a mineralized adjustable water purification system provided in an embodiment of the present application. Figure 3 As shown, the method includes:

[0061] S301, receiving a mineral content adjustment instruction, and determining a target mineral concentration range corresponding to the mineral content adjustment instruction.

[0062] The execution subject of the present application may be a controller electrically connected to various components of the mineralization adjustable water purification system.

[0063] In the embodiment of this specification, when the user wants to adjust the mineral content of the water, the user can perform corresponding selection operations on the operating objects such as buttons or touch screens set on the shell of the water purification system to select the concentration he wants. The concentration that the user can choose is generally a concentration range, rather than a specific concentration value. For example, the operating object can display options such as no concentration, low concentration, medium concentration, high concentration, and ultra-high concentration, and the user makes corresponding choices according to his needs. If you want the user to be able to select a specific concentration, a detection probe 15 needs to be set in the system, and the first fluid control component 13 and the second fluid control component 9 are preferably control pumps, so that the working flow required by the control pump to achieve a specific concentration can be accurately calculated according to the calculation formula of the aforementioned embodiment. After the user completes the selection, the operating object will generate a corresponding mineral content adjustment instruction and send it to the controller. The controller can determine the target mineral concentration range to be adjusted this time by parsing the mineral content adjustment instruction.

[0064] S303, generating a control instruction based on a preset control rule corresponding to the target mineral concentration range, wherein the control instruction is used to control the opening and closing states of the air intake component 4, the first fluid control component 13 and the second fluid control component 9 respectively according to the preset control rule.

[0065] In the embodiment of the present specification, different preset control rules are pre-set for different target mineral concentration ranges, and the preset control rules can be used to characterize the control method for the opening and closing states of the air intake component 4, the first fluid control component 13, and the second fluid control component 9. The controller will generate control instructions according to the determined preset control rules, and send the control instructions to the air intake component 4, the first fluid control component 13, and the second fluid control component 9 respectively, so as to control the opening and closing states of the air intake component 4, the first fluid control component 13, and the second fluid control component 9 respectively, so as to achieve concentration adjustment.

[0066] As an example, assuming that the adjustable concentration is divided into five gears, namely, no concentration, low concentration, medium concentration, high concentration, and ultra-high concentration, the preset control rule corresponding to no concentration may be that the air intake component 4 is closed, the first fluid control component 13 is closed, and the second fluid control component 9 is opened. The preset control rule corresponding to the low concentration may be that the air intake component 4 is closed, the first fluid control component 13 is opened, and the second fluid control component 9 is opened. The preset control rule corresponding to the medium concentration may be that the air intake component 4 is closed, the first fluid control component 13 is opened, and the second fluid control component 9 is closed. The preset control rule corresponding to the high concentration may be that the air intake component 4 is opened, the first fluid control component 13 is opened, and the second fluid control component 9 is opened. The preset control rule corresponding to the ultra-high concentration may be that the air intake component 4 is opened, the first fluid control component 13 is opened, and the second fluid control component 9 is closed. In other embodiments, five gears may not be set, but some gears may be selected from them as gears that the user can select, or the user may be required to input a specific desired concentration value.

[0067] In one embodiment, the method further comprises:

[0068] Determine the current mineral concentration at the system water outlet 11;

[0069] When the current mineral concentration does not match the target mineral concentration range, the number of abnormalities is counted cumulatively, and the current mineral concentration at the system water outlet 11 is re-determined after a preset waiting time;

[0070] When the current mineral concentration matches the target mineral concentration range, the number of abnormal times is cleared;

[0071] When the number of abnormalities is greater than a preset number, a prompt message is generated, and the prompt message is used to indicate that the mineralized filter element 14 needs to be replaced.

[0072] In the embodiment of the present specification, the controller can determine the current mineral concentration of the system outlet 11 according to the detection data of the detection probe 15 or according to the working flow of each fluid control component. If the current mineral concentration obtained does not match the target mineral concentration range, it is considered that the mineralized filter element 14 may be abnormal, but since it may also be that the concentration in the fluid pipeline has not changed to the target concentration in a short time, the controller will accumulate and count the number of abnormalities and re-determine the current mineral concentration after waiting for a preset waiting time. If it is detected that the current mineral concentration matches the target mineral concentration range, the controller believes that the mineralized filter element 14 is not abnormal and will reset the number of abnormalities. If after several rounds of detection, the current mineral concentration does not meet the requirements, so that the number of abnormalities is greater than the preset number, the controller will consider that the trial of the mineralized filter element 14 has expired, resulting in abnormal current mineral concentration. At this time, the controller will generate a prompt message to prompt the user to inform him that the filter element needs to be replaced. The specific expression of the prompt information can be an audio and visual prompt, or a text prompt, a text prompt, etc.
