[0048] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments.

[0049] Embodiment 1

[0050] For the mineral adjustment method of the water purifier in this embodiment, the water purifier includes a first water purification system, a second water purification system, and a proportion adjustment system. The first water purification system and the second water purification system are both connected to the proportion adjustment system. The second water purification system includes a pre-membrane ion concentration detection module, a first membrane filter element, and a post-membrane ion concentration detection module. One end of the first membrane filter element is connected to the pre-membrane ion concentration detection module, and the other end of the first membrane filter element is connected to the post-membrane ion concentration detection module. The proportion adjustment system includes a mixing valve. As Figure 1 shown, the mineral adjustment method includes:

[0051] S11. Use the pre-membrane ion concentration detection module and the post-membrane ion concentration detection module to detect the liquid water in the second water purification system, obtain the corresponding first detection data and second detection data, and obtain the monovalent ion rejection rate and divalent ion rejection rate of the first membrane filter element;

[0052] S12. Calculate the target divalent ion contribution value according to the monovalent ion rejection rate, divalent ion rejection rate, first detection data, and second detection data;

[0053] S13. Calculate the monovalent ion mineral retention value and the divalent ion mineral retention value according to the monovalent ion rejection rate, divalent ion rejection rate, and target divalent ion contribution value;

[0054] S14. Adjust the mixing valve based on the comparison result between the monovalent ion mineral retention value or the divalent ion mineral retention value and the set retention value, so that the first water purification system passes water in proportion to achieve mineral adjustment.

[0055] In this embodiment, as Figure 2 shown, in the first schematic diagram of the water purifier, the second water purification system includes a pre-filter, a power module, a pre-membrane ion concentration detection module ( Figure 2 shown as detection module 1 in Figure 2 ), a first membrane filter element, and a post-membrane ion concentration detection module (

[0056] Regarding the above steps S11 - S14, assume that the first water purification system has no removal effect on mineral ions. For example, set up PP cotton, activated carbon, or ultrafiltration filter elements, etc. If the liquid water in the second water purification system only includes divalent ions and monovalent ions, the divalent ions include calcium ions and magnesium ions, and the monovalent ions include sodium ions and potassium ions.

[0057] Set the rejection rate of the first membrane filter element in the second water purification system for divalent ions as a, and the rejection rate for monovalent ions as b, and a > b. The percentage of ions passing through the first membrane filter element is 1 - a and 1 - b respectively. Taking the TDS sensor as an example for the pre - membrane ion concentration detection module and the post - membrane ion concentration detection module, if the pre - membrane ion concentration detection module obtains the first detection data T1, and the post - membrane ion concentration detection module obtains the second detection data T2, the target divalent ion contribution value is Tax = (T2 - T1+T1*b) / (b - a). The divalent ion mineral retention value is: Tax*(1 - a), and the monovalent ion mineral retention value is: (T1 - Tax)*(1 - b), with the unit of mg / L. Select either the monovalent ion mineral retention value or the divalent ion mineral retention value as the reference point for mineral adjustment, and compare it with the set retention value, so that the first water purification system conducts water flow according to a ratio to achieve mineral adjustment. This method calculates the ion mineral retention value through the detection data before and after the first membrane filter element in the second water purification system, and adjusts the proportion adjustment system according to the comparison result between the ion mineral retention value and the set retention value to control the water flow rate of the first water purification system, realizing the automatic and flexible control of the mineral content corresponding to the user's needs.

[0058] In one embodiment, step S14 specifically includes:

[0059] If the monovalent ion mineral retention value or the divalent ion mineral retention value is not less than the set retention value, adjust the mixing valve to control the first water purification system to stop water flow;

[0060] If the divalent ion mineral retention value or the divalent ion mineral retention value is less than the set retention value, adjust the mixing valve to control the first water purification system to conduct water flow according to the set ratio.

[0061] In this embodiment, it is determined whether the monovalent ion mineral retention value and the divalent ion mineral retention value meet the requirements, and then the opening or closing of the mixing valve is controlled according to the comparison result. For example, when the divalent ion mineral retention value or the monovalent ion mineral retention value is 10 and the set retention value is 8, the mixing valve is closed so that the first water purification system is not supplied with water, and all the water in the water inlet pipe flows through the second water purification system for filtration, ultimately reducing the mineral retention value. Since the first water purification system has a low interception rate and a high retention rate for mineral ions, and the second water purification system has a high interception rate and a low retention rate for mineral ions, after closing the mixing valve, the amount of liquid water flowing out of the first water purification system is reduced, effectively reducing the ion mineral retention value. When the divalent ion mineral retention value or the monovalent ion mineral retention value is 8 and the set retention value is 10, the mixing valve is opened so that the first water purification system supplies water in proportion, and part of the water in the water inlet pipe flows through the second water purification system for filtration, ultimately increasing the mineral retention value. Since the first water purification system has a low interception rate and a high retention rate for mineral ions, and the second water purification system has a high interception rate and a low retention rate for mineral ions, after opening the mixing valve, the amount of liquid water flowing out of the first water purification system is increased, effectively increasing the ion mineral retention value.

[0062] In one embodiment, the proportional adjustment system further includes a first flow meter and a second flow meter. The first flow meter is connected to the first water purification system, and the second flow meter is connected to the second water purification system. As Figure 4 shown, step S13 specifically includes:

[0063] S131. Collect the corresponding first flow data and second flow data by using the first flow meter and the second flow meter;

[0064] S132. Calculate the monovalent ion mineral retention value and the divalent ion mineral retention value according to the monovalent ion interception rate, the divalent ion interception rate, the target divalent ion contribution value, the first flow data and the second flow data.

[0065] In this embodiment, as Figure 3 shown, in the second structural schematic diagram of the water purifier, the proportional adjustment system further includes a first flow meter and a second flow meter. One end of the first flow meter is connected to the water outlet pipeline of the first water purification system, the other end of the first flow meter is connected to the mixing valve, the second flow meter is connected to the water outlet pipeline of the second water purification system, and the other end of the second flow meter is connected to the mixing valve.

[0066] For the above steps S131 - S132, if the first flowmeter and the second flowmeter are used to collect the corresponding first flow data L1 and second flow data L2, the retention value of divalent ion minerals is: Tax*(1 - a)*L2 + Tax*L1 / (L1 + L2), and the retention value of monovalent ion minerals is: (T1 - Tax)*(1 - b)*L2 + (T1 - Tax)*L1 / (L1 + L2), with the unit of mg / L. It should be noted that the calculation formulas for the retention values of monovalent ion minerals and divalent ion minerals can be adaptively adjusted to improve the accuracy of the calculation of mineral retention values.

[0067] In one embodiment, the first water purification system includes a second membrane filter element, and the proportional adjustment system further includes a first flowmeter and a second flowmeter. As Figure 5 shown, step S13 specifically includes:

[0068] S131. Use the first flowmeter and the second flowmeter to collect the corresponding first flow data and second flow data;

[0069] S133. Obtain the monovalent ion rejection rate and divalent ion rejection rate of the second membrane filter element;

[0070] S134. Calculate the retention values of monovalent ion minerals and divalent ion minerals according to the monovalent ion rejection rate and divalent ion rejection rate of the second membrane filter element, the monovalent ion rejection rate, divalent ion rejection rate, target divalent ion contribution value, first flow data and second flow data.

[0071] In this embodiment, as Figure 3 shown, in the second structural schematic diagram of the water purifier, the proportional adjustment system further includes a first flowmeter and a second flowmeter. One end of the first flowmeter is connected to the water outlet pipeline of the first water purification system, the other end of the first flowmeter is connected to the mixing valve, the second flowmeter is connected to the water outlet pipeline of the second water purification system, the other end of the second flowmeter is connected to the mixing valve, and the first water purification system includes a second membrane filter element.

[0072] For the above steps S131, S133, and S134, the second membrane filter element of the first water purification system has an ion rejection effect. Set the divalent ion rejection rate of the second membrane filter element as c and the monovalent ion rejection rate as d. The divalent ion rejection rate is: (Tax*(1 - a)*L2 + Tax*(1 - c)*L1) / (L1 + L2), and the monovalent ion rejection rate is: (((T1 - Tax)*(1 - b)*L2 + (T1 - Tax)*(1 - d)*L1) / (L1 + L2)), with the unit of mg / L. It should be noted that the calculation formulas for the retention values of monovalent ion minerals and divalent ion minerals can be adaptively adjusted to improve the accuracy of the calculation of mineral retention values.

[0073] In this embodiment, a method for adjusting minerals in a water purifier is provided. The ion mineral retention value is calculated based on the detection data before and after the first membrane filter element in the second water purification system. The ratio adjustment system is adjusted according to the comparison result between the ion mineral retention value and the set retention value to control the water flow rate of the first water purification system, so as to automatically adjust the mineral content according to user needs and enhance the user experience.

[0074] Embodiment 2

[0075] The mineral adjustment system of the water purifier in this embodiment. The water purifier includes a first water purification system, a second water purification system, and a ratio adjustment system. The first water purification system and the second water purification system are both connected to the ratio adjustment system. The second water purification system includes a pre-membrane ion concentration detection module, a first membrane filter element, and a post-membrane ion concentration detection module. One end of the first membrane filter element is connected to the pre-membrane ion concentration detection module, and the other end of the first membrane filter element is connected to the post-membrane ion concentration detection module. The ratio adjustment system includes a mixing valve. As Figure 6 shown, the mineral adjustment system includes:

[0076] A detection module 310, configured to use the pre-membrane ion concentration detection module and the post-membrane ion concentration detection module to detect the liquid water in the second water purification system, obtain corresponding first detection data and second detection data, and obtain the monovalent ion rejection rate and divalent ion rejection rate of the first membrane filter element;

[0077] A first calculation module 320, configured to calculate a target divalent ion contribution value according to the monovalent ion rejection rate, the divalent ion rejection rate, the first detection data, and the second detection data;

[0078] A second calculation module 330, configured to calculate a monovalent ion mineral retention value and a divalent ion mineral retention value according to the monovalent ion rejection rate, the divalent ion rejection rate, and the target divalent ion contribution value;

[0079] An adjustment module 340, configured to adjust the mixing valve based on the comparison result between the monovalent ion mineral retention value or the divalent ion mineral retention value and the set retention value, so that the first water purification system passes water in proportion to achieve mineral adjustment.

[0080] In this embodiment, it is assumed that the first water purification system has no effect on removing mineral ions. For example, a PP cotton, activated carbon, or ultrafiltration filter element is set. If the liquid water in the second water purification system only includes divalent ions and monovalent ions, the divalent ions include calcium ions and magnesium ions, and the monovalent ions include sodium ions and potassium ions.

[0081] Set the retention rate of divalent ions by the first membrane filter element in the second water purification system as a, and the retention rate of monovalent ions as b, and a > b. The ion percentage passing through the first membrane filter element is 1 - a and 1 - b respectively. Taking the TDS sensor as an example, for the pre-membrane ion concentration detection module and the post-membrane ion concentration detection module, if the pre-membrane ion concentration detection module obtains the first detection data T1, and the post-membrane ion concentration detection module obtains the second detection data T2, the first calculation module 320 calculates the target divalent ion contribution value as Tax = (T2 - T1 + T1 * b) / (b - a). The second calculation module 330 calculates the divalent ion mineral retention value as Tax * (1 - a), and the monovalent ion mineral retention value as (T1 - Tax) * (1 - b), with the unit of mg / L. The adjustment module 340 selects either the monovalent ion mineral retention value or the divalent ion mineral retention value as the reference point for mineral adjustment, and compares it with the set retention value, so that the first water purification system conducts water according to a ratio to achieve mineral adjustment. This method calculates the ion mineral retention value through the detection data before and after the first membrane filter element in the second water purification system, and adjusts the ratio adjustment system according to the comparison result between the ion mineral retention value and the set retention value to control the water flow rate of the first water purification system, realizing automatic and flexible control of the mineral content corresponding to the user's needs.

[0082] As Figure 7 shown, the adjustment module 340 includes:

[0083] The first adjustment unit 341 is used to adjust the mixing valve to control the first water purification system to stop conducting water if the monovalent ion mineral retention value or the divalent ion mineral retention value is not less than the set retention value;

[0084] The second adjustment unit 342 is used to adjust the mixing valve to control the first water purification system to conduct water according to the set ratio if the monovalent ion mineral retention value or the divalent ion mineral retention value is less than the set retention value.

[0085] In this embodiment, it is determined whether the monovalent ion mineral retention value and the divalent ion mineral retention value meet the requirements, and then the opening or closing of the mixing valve is controlled according to the comparison result. For example, when the divalent ion mineral retention value or the monovalent ion mineral retention value is 10 and the set retention value is 8, the first adjustment unit 341 closes the mixing valve so that the first water purification system is not supplied with water, and all the water in the water inlet pipe flows through the second water purification system for filtration, finally reducing the mineral retention value. Since the first water purification system has a low interception rate and a high retention rate of mineral ions, and the second water purification system has a high interception rate and a low retention rate of mineral ions, after closing the mixing valve, the amount of liquid water flowing out of the first water purification system is reduced, effectively reducing the ion mineral retention value. When the divalent ion mineral retention value or the monovalent ion mineral retention value is 8 and the set retention value is 10, the second adjustment unit 342 opens the mixing valve so that the first water purification system supplies water according to a ratio, and part of the water in the water inlet pipe flows through the second water purification system for filtration, finally increasing the mineral retention value. Since the first water purification system has a low interception rate and a high retention rate of mineral ions, and the second water purification system has a high interception rate and a low retention rate of mineral ions, after opening the mixing valve, the amount of liquid water flowing out of the first water purification system is increased, effectively increasing the ion mineral retention value.

[0086] In one embodiment, the proportional adjustment system further includes a first flow meter and a second flow meter. The first flow meter is connected to the first water purification system, and the second flow meter is connected to the second water purification system, as Figure 7 shown, the second calculation module 330 includes:

[0087] An acquisition unit 331 for acquiring corresponding first flow data and second flow data by using the first flow meter and the second flow meter;

[0088] A first calculation unit 332 for calculating the monovalent ion mineral retention value and the divalent ion mineral retention value according to the monovalent ion interception rate, the divalent ion interception rate, the target divalent ion contribution value, the first flow data and the second flow data.

[0089] In this embodiment, in the second structural schematic diagram of the water purifier, the proportional adjustment system further includes a first flow meter and a second flow meter. One end of the first flow meter is connected to the water outlet pipeline of the first water purification system, the other end of the first flow meter is connected to the mixing valve, the second flow meter is connected to the water outlet pipeline of the second water purification system, and the other end of the second flow meter is connected to the mixing valve.

[0090] If the first flowmeter and the second flowmeter are used to collect the corresponding first flow data L1 and second flow data L2, the retention value of divalent ion minerals is: Tax*(1 - a)*L2 + Tax*L1 / (L1 + L2), and the retention value of monovalent ion minerals is: (T1 - Tax)*(1 - b)*L2 + (T1 - Tax)*L1 / (L1 + L2), with the unit of mg / L. It should be noted that the calculation formulas for the retention values of monovalent ion minerals and divalent ion minerals can be adaptively adjusted to improve the accuracy of the calculation of mineral retention values.

[0091] In one embodiment, the first water purification system includes a second membrane filter element. The proportion adjustment system further includes a first flowmeter and a second flowmeter.

[0095] In this embodiment, in the second structural schematic diagram of the water purifier, the proportion adjustment system further includes a first flowmeter and a second flowmeter. One end of the first flowmeter is connected to the water outlet pipeline of the first water purification system, the other end of the first flowmeter is connected to the mixing valve, the second flowmeter is connected to the water outlet pipeline of the second water purification system, the other end of the second flowmeter is connected to the mixing valve, and the first water purification system includes a second membrane filter element.

[0096] The second membrane filter element of the first water purification system has an ion rejection effect. Set the divalent ion rejection rate of the second membrane filter element as c and the monovalent ion rejection rate as d. The divalent ion rejection rate is: (Tax*(1 - a)*L2 + Tax*(1 - c)*L1) / (L1 + L2), and the monovalent ion rejection rate is: ((T1 - Tax)*(1 - b)*L2 + (T1 - Tax)*(1 - d)*L1) / (L1 + L2), with the unit of mg / L. It should be noted that the calculation formulas for the retention values of monovalent ion minerals and divalent ion minerals can be adaptively adjusted to improve the accuracy of the calculation of mineral retention values.
