Description

Technical Field

[0001] The present application relates to the technical field of water treatment equipment, and in particular to a water system for a mineral water purifier and a mineral water purifier. Background Art

[0002] With the improvement of productivity, people's demand for quality of life and convenience is also increasing. Alkaline water is a kind of water with a pH value greater than 7. Drinking alkaline water in moderation can replenish water, improve microcirculation, and promote metabolism. At the same time, alkaline water also has an improvement function in the case of water and electrolyte disorders. For example, after a lot of vomiting, drinking alkaline water can help replenish water. In addition, alkaline water can also help neutralize excess gastric acid, protect gastric mucosa, and reduce the possibility of peptic ulcers. Therefore, mineralized water is widely favored as drinking water. At the same time, there is also a certain demand for alkaline water during production and experiments.

[0003] At present, there are two common ways to prepare alkaline water.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] With the improvement of productivity, people's demand for quality of life and convenience is also increasing. Alkaline water is a kind of water with a pH value greater than 7. Drinking alkaline water in moderation can replenish water, improve microcirculation, and promote metabolism. At the same time, alkaline water also has an improvement function in the case of water and electrolyte disorders. For example, after a lot of vomiting, drinking alkaline water can help replenish water. In addition, alkaline water can also help neutralize excess gastric acid, protect gastric mucosa, and reduce the possibility of peptic ulcers. Therefore, mineralized water is widely favored as drinking water. At the same time, there is also a certain demand for alkaline water during production and experiments.

[0032] At present, there are two common ways to prepare alkaline water. The first is to manually mix alkaline substances with water to make alkaline water with a suitable pH value, but this method is very troublesome, has a certain threshold of chemical knowledge and is inefficient. The second is to put alkaline filter material into a container filled with water, such as a drinking fountain or a water purifier. The alkaline substances in the alkaline filter material can dissolve into the water in the container, turning the water into alkaline water. In the early stage of use, a large amount of alkaline substances enter the water, causing the pH value of the alkaline water to be too high during this period; in the later stage of use, the content of alkaline substances in the alkaline filter material decreases, resulting in less alkaline substances entering the water, and the pH value of the alkaline water is too low during this period. Alkaline water with a pH value that is too high or too low cannot meet water demand, which greatly affects the availability of alkaline filter materials.

[0033] In order to improve or solve the above technical problems, the inventors of the present application have proposed at least the following embodiments after long-term research.

[0034] See also Figure 3 , Figure 4 , Figure 3 A schematic diagram of the water channel structure of an embodiment of a water channel system for a mineral water purifier provided in the present application. Figure 4 This is a schematic diagram of the water circuit structure of another embodiment of the water circuit system for a mineral water purifier provided by the present application. The specific implementation of the present application provides a water circuit system for a mineral water purifier, which is used to process a fluid to output alkaline water.

[0035] The water system for a mineral water purifier may include a first alkaline filter material 1 , a second alkaline filter material 2 and an alkaline water channel 43 . The alkalinity of the first alkaline filter material 1 is greater than that of the second alkaline filter material 2 . The first alkaline filter material 1 can be used to inhibit the second alkaline filter material 2 from releasing alkaline substances.

[0036] In the alkaline water channel 43, the first alkaline filter material 1 and the second alkaline filter material 2 may be sequentially arranged along a preset water flow direction. Alternatively, the alkaline water channel 43 may be provided with a filter material installation cavity 3 for simultaneously accommodating the first alkaline filter material 1 and the second alkaline filter material 2.

[0037] In the structure provided in this specific embodiment, by simultaneously arranging the first alkaline filter material 1 and the second alkaline filter material 2 in the alkaline water channel 43, the first alkaline water flowing through the first alkaline filter material 1 and the second alkaline water flowing through the second alkaline filter material 2 can be prepared, so that alkaline water with moderate alkalinity and meeting the use requirements can be prepared for use using the first alkaline water and the second alkaline water with different alkalinities, which can reduce the probability of the pH value of the final output water of the water channel system for the mineral water purifier being too high, and can improve the safety and stability of the water channel system for the mineral water purifier.

[0038] Furthermore, when the first alkaline filter material 1 and the second alkaline filter material 2 are arranged in the same filter material installation cavity 3, during the service life of the water system used for the mineral water purifier, the first alkaline filter material 1 with stronger alkalinity can suppress the second alkaline filter material 2 with weaker alkalinity in the initial stage of use. The strong alkaline filter material releases alkaline substances in the early stage and releases alkaline substances together with the weak alkaline filter material in the middle and late stages. The two can work synergistically to greatly improve the life of the filter element in the alkaline water path 43, thereby achieving a longer life of the filter element.

[0039] In a specific application, the second alkaline filter material 2 can be a weak alkaline filter material, and the first alkaline filter material 1 can be a strong alkaline filter material. The alkalinity between the weak alkaline filter material and the strong alkaline filter material can be a relative concept, that is, the alkalinity of the first alkaline filter material 1 is higher than the alkalinity of the second alkaline filter material 2. The alkaline substances released by the first alkaline filter material 1 and the second alkaline filter material 2 can include hydroxide ions OH - and bicarbonate ions HCO3 - .

[0040] The strong alkaline filter material can be made of strong alkaline materials, such as at least one of brucite, periclase, sepiolite, magnesite and the like. Taking brucite as an example, brucite contains Mg(OH)2, which enables brucite to react in water to release (dissolve) OH - , which can enhance the alkalinity of the water body and increase the pH value of the water body to obtain alkaline water.

[0041] Reaction A: Mg(OH)2=Mg 2+ +2OH -

[0042] The weakly alkaline filter material can be made of weakly alkaline materials, such as at least one of calcite, dolomite, stalactite, limestone, Iceland spar, etc. Taking calcite as an example, calcite contains CaCO3. When calcite is immersed in water, reaction B will first occur to release CO3 in the water. 2- , then CO3 2- Can undergo hydrolysis reaction with H2O to generate OH - .

[0043] Reaction B: CaCO3=Ca 2+ +CO3 2-

[0044] Reaction C:

[0045] It can be found that the strong alkaline filter material only needs one step reaction to obtain OH - , weakly alkaline filter materials require two steps of reaction to obtain OH - , and the rate of reaction C is much lower than that of reaction A, so the strong alkaline material will preferentially dissolve OH into the water. - Moreover, reaction C is a reversible reaction. When reaction A occurs first, the chemical equilibrium of reaction C will shift to the left. Therefore, the strong alkaline filter material can inhibit the OH of the weak alkaline filter material. - release.

[0046] like Figure 3 As shown, the strong alkaline filter material and the weak alkaline filter material are combined to form a parallel structure, and the fluid in the alkaline waterway 43 flows through the strong alkaline filter material and the weak alkaline filter material at the same time. Furthermore, the strong alkaline filter material and the weak alkaline filter material can be respectively arranged in two filter elements, or assembled in the same filter element. When the strong alkaline filter material and the weak alkaline filter material are located in the same filter element, the inhibitory effect of the strong alkaline filter material on the weak alkaline filter material can be utilized. During the service life of the entire filter element, the strong alkaline filter material releases OH in the early stage. - , and releases OH together with weakly alkaline filter materials in the middle and late stages - The two can work together to greatly increase the life of the filter element in the alkaline water path 43, thereby extending the life of the filter element.

[0047] like Figure 4 As shown, the strong alkaline filter material and the weak alkaline filter material are combined to form an axially integrated structure, and the fluid in the alkaline waterway 43 first flows through the strong alkaline filter material and then flows through the weak alkaline filter material. Furthermore, the strong alkaline filter material and the weak alkaline filter material can be respectively arranged in two filter elements, or assembled in the same filter element. When the strong alkaline filter material and the weak alkaline filter material are located in the same filter element, the inhibitory effect of the strong alkaline filter material on the weak alkaline filter material can be utilized. During the service life of the entire filter element, the strong alkaline filter material releases OH in the early stage. - , and releases OH together with weakly alkaline filter materials in the middle and late stages - The two can work together to greatly increase the life of the filter element in the alkaline water path 43, thereby extending the life of the filter element.

[0048] See also Figure 1 , Figure 2 , Figure 1 This is the pH value trend chart of the first alkaline filter material and the second alkaline filter material alone. Figure 2 , Figure 2 The pH value change trend diagram of the first alkaline filter material alone, the second alkaline filter material alone, and the mixed water. The following multiple embodiments are obtained by adjusting the mass ratio of the strong alkaline filter material to the weak alkaline filter material. The pH value of the water flowing through each embodiment at different flow rates is tested, and Table 1 is obtained as follows. Among them, the adjustment range of the mass ratio of the strong alkaline filter material is 10% to 50%, and correspondingly, the adjustment range of the mass ratio of the weak alkaline filter material is 50%-90%.

[0049] Table 1

[0050]

[0051] Based on Table 1 Figure 1 , Figure 2 According to analysis, when the proportion of strong alkaline filter material is 0%, that is, there is only weak alkaline filter material, due to the slow dissolution rate of the weak alkaline filter material itself and poor ability to alkalize water quality, the pH value of the water outlet is less than 7 when the first 2000L of water flows through, and alkaline water that meets water demand cannot be obtained in the early stage. Afterwards, as the flow rate increases, the pores inside the weak alkaline material gradually become connected from closed under the impact of water flow, and the water flow can pass not only from the surface of the material, but also from the inside of the material, which increases the contact area between water molecules and mineralized materials, increases the reaction rate, and gradually increases the pH value of the flowing water to above 7.

[0052] When the proportion of strong alkaline filter material increases to 5%, the pH value at 0L increases. This is because the strong alkaline filter material releases OH into the flowing water at the beginning. -When the proportion of strong alkaline filter material is between 10-50%, the pH value can be maintained between 7.0-9.0 throughout the life span, thus obtaining alkaline water that meets water demand.

[0053] When the strong alkaline filter material accounts for 60%, the pH value at the beginning reaches 9.15, which exceeds the range of weak alkaline water and does not meet the water demand. When the strong alkaline filter material accounts for 100%, the pH value at the beginning reaches 10.12, far exceeding the upper limit of 9, and decays quickly. When the flow rate reaches 6000L, the pH value is less than 7. This is because the strong alkaline material releases OH into the flow water. - Strong ability, but due to OH - Too fast dissolution causes the alkaline substances contained in the strong alkaline filter material to be consumed quickly, which weakens the filter element's ability to produce alkaline water in the later stages of use.

[0054] It should be noted that Figure 1 , Figure 2 In the method, different combinations of the first alkaline filter material 1 and the second alkaline filter material 2 may be used, or the flow rate and / or flow velocity of the flowing water body may be different. The alkalinity of the alkaline substances dissolved into the water body by different first alkaline filter materials 1 may not be the same. The alkalinity of the alkaline substances dissolved into the water body by different second alkaline filter materials 2 may not be the same. The amount of alkaline substances contained in the flowing water with different flow rates and / or flow velocities may not be the same.

[0055] Due to many reasons, Figure 1 The curve representing the strong alkaline water flow shows the pH value during the service life cycle, which is different from Figure 2 The curve representing the strongly alkaline mineral water shows different pH values ​​during its service life, but at the same time, it is not difficult to see Figure 1 and Figure 2 The curves in have similar changing trends, and the same is true for weak alkaline flow water and weak alkaline mineral water.

[0056] Therefore, although the specific values ​​are different, the combination of the first alkaline filter material 1 and the second alkaline filter material 2 can have similar effects on the pH value of the alkaline water output by the water system.

The first water quality detection component 61 is arranged in the alkaline water channel 43 to measure the water quality of the alkaline water. Through the water quality of the alkaline water, the ratio of alkaline water and purified water required to be adjusted to a specified pH range can be calculated.

[0067] Therefore, by setting up the first water quality detection component 61, the water quality of the water in the water system can be effectively monitored, so that the controller can adjust at least one of the valve bodies such as the first diverter valve 51, the first flow valve, and the second flow valve according to the feedback of the water quality, which can improve the accuracy of the water system in regulating the alkalinity of the water output, enable the water system to output water that better meets the needs of users, and improve the availability of the water system.

[0076] In the structure provided in this specific embodiment, the first return waterway can be used to return the water in the pure waterway 42 to the water purification component 7, thereby reducing the probability of excessive purified water causing a low pH value of the outlet water and avoiding waste of purified water. At the same time, the first return waterway can also transport the purified water that does not meet the use standards back to the water purification component 7 for re-filtration, so as to reduce the probability of unqualified water quality in the water outlet 44.

[0077] In a specific embodiment provided by the present application, the device body may further include a communication component, which is connected to the controller. The communication component may be used to receive a water quality control message, and the controller may control the water system according to the water quality control message, and then output water that meets the water quality control message through the water outlet 44.

[0078] The specific embodiment of the present application also provides a mineral water purifier, including a water outlet component and a water system for a mineral water purifier as described in any of the above specific embodiments. The water outlet component is used to discharge water to the outside, and the water outlet component is connected to the water outlet 44 of the water system for the mineral water purifier.

[0079] In the structure provided in this specific embodiment, by simultaneously arranging the first alkaline filter material 1 and the second alkaline filter material 2 in the alkaline water channel 43, the first alkaline water flowing through the first alkaline filter material 1 and the second alkaline water flowing through the second alkaline filter material 2 can be prepared, so that alkaline water with moderate alkalinity and meeting the use requirements can be prepared for use using the first alkaline water and the second alkaline water with different alkalinities, which can reduce the probability of the pH value of the final output water of the water channel system for the mineral water purifier being too high, and can improve the safety and stability of the water channel system for the mineral water purifier.

[0080] Furthermore, when the first alkaline filter material 1 and the second alkaline filter material 2 are arranged in the same filter material installation cavity 3, during the service life of the water system used for the mineral water purifier, the first alkaline filter material 1 with stronger alkalinity can suppress the second alkaline filter material 2 with weaker alkalinity in the initial stage of use. The strong alkaline filter material releases alkaline substances in the early stage and releases alkaline substances together with the weak alkaline filter material in the middle and late stages. The two can work synergistically to greatly improve the life of the filter element in the alkaline water path 43, thereby achieving a longer life of the filter element.

[0081] The specific implementation of the present application can also provide a control method for a mineral water purifier, see Figure 5 , Figure 5FIG. 1 is a flow chart of an embodiment of a control method for a mineral water purifier. It should be noted that if there are substantially the same results, this embodiment is not limited to Figure 5 The process sequence shown is limited. Figure 5 As shown, the control method of the mineral water purifier may include:

[0082] S100: receiving a water quality control message.

[0083] S200 : In response to the water quality control message, the first diverter valve 51 is controlled to adjust the flow ratio of the input alkaline water path 43 and the input pure water path 42 .

[0084] The executor of the control method of the mineral water purifier provided in the present application may be a controller of the water system of the mineral water purifier, which is connected to the first diverter valve 51 and can receive water quality control messages, thereby controlling the water quality of the water body output from the water outlet 44 by adjusting the flow ratio of the input alkaline water channel 43 and the pure water channel 42.

[0085] The water quality control message can be generated locally in the mineral water purifier device, for example, the user inputs instructions to the mineral water purifier to generate the corresponding water quality control message by operating the mineral water purifier. It can also be generated on the client side, where the client side is connected to the mineral water purifier through a communication component, and the communication component receives the water quality control message generated and sent by the client side, and transmits the water quality control message to the controller.

[0086] See also Figure 6 , Figure 6 FIG. 1 is a flow chart of another embodiment of a control method for a mineral water purifier. It should be noted that if there is substantially the same result, this embodiment is not limited to the above. Figure 6 The process sequence shown is limited. Figure 6 As shown, the control method of the mineral water purifier may also include:

[0087] S300: Obtain a total flow parameter from the first flow detection component 62, and determine whether the total flow parameter is greater than or equal to a first threshold.

[0088] S400 : In response to the total flow parameter being greater than or equal to the first threshold, the first diverter valve 51 is controlled to adjust the flow input to the pure water path 42 to zero, the flow input to the alkaline water path 43 to the maximum, and the water quality parameter is obtained from the first water quality detection component 61 .

[0089] S500: Determine whether the water quality parameter is less than a second threshold.

[0090] S600: In response to the water quality parameter being less than the second threshold, a filter element replacement message is generated and sent using a communication component.

[0091] Through the method provided in this specific embodiment, the service life of the water system can be monitored using the total flow parameter measured by the first flow detection element 62. When the total flow parameter is greater than or equal to the first threshold, the water system is promptly adjusted to only discharge water from the alkaline water channel 43, and then the alkaline filter element can be judged by the water quality parameter whether it can still work normally to prepare alkaline water, and when the alkaline filter element cannot work normally, the filter element replacement message is used to notify the user to replace it, which greatly improves the availability of the mineral water purifier.
