Description

Technical Field

[0001] The present application relates to the field of water purification technology, and in particular to a mineralized water system and a mineralized water purifier. Background Art

[0002] A mineral water purifier is a water purification device that can deeply purify tap water and add the mineral elements needed by the human body to make the water quality reach the standard of mineral water. The mineral water purifier adds mineral-rich filter materials to reintegrate calcium, magnesium, iron, zinc and other minerals needed by the human body into the water. These minerals exist in ionic state and are easier for the human body to absorb.

[0003] However, when the reverse osmosis water purifier is working normally, water molecules pass through the membrane under external pressure and enter the pure water side, while salt ions remain on the concentrated water side, so the total dissolved solids (TDS) in the water can be maintained within the normal range. However, when the reverse osmosis water purifier stops working, TDS will penetrate the membrane through the action of forward osmosis, causing the TDS value to exceed the normal range. Therefore, whenever the reverse osmosis water purifier stops for a period of time and then restarts water production, the TDS value of the first cup of water will be relatively high. Summary of the invention

[0004] Based on this, the embodiments of the present application propose a mineralized water system and a mineralized water purifier, which can achieve a buffering effect and provide sufficient mixed water during backflow flushing, so that the filter membrane of the reverse osmosis filter unit can be flushed more fully, thereby reducing the TDS value and solving the problem of high TDS value caused by short-frequency water intake.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present application.

[0031] Figure 1 It is a structural schematic diagram of a mineralized waterway system according to an embodiment of the present application.

[0032] The mineralized water system 1 may include: a water inlet pipeline 10 , a pre-filter unit 201 , a reverse osmosis filter unit 202 , a mineralized filter unit 203 , and a water pump 204 .

[0033] Among them, one side of the water inlet pipe 10 is the raw water inlet side, which is used to receive raw water. The other side of the water inlet pipe 10 is connected to the water inlet side of the pre-filter unit 201, which is used to flow raw water into the pre-filter unit 201 for water purification. The water pump 204 is arranged between the pre-filter unit 201 and the reverse osmosis filter unit 202. Specifically, the water inlet side of the water pump 204 is connected to the water outlet side of the pre-filter unit 201, and the water outlet side of the water pump 204 is connected to the water inlet side of the reverse osmosis filter unit 202. The water inlet side of the mineralized filter unit 203 is connected to the pure water side of the reverse osmosis filter unit 202.

[0034] In one embodiment, the pre-filter unit 201, the water pump 204, the pure water side of the reverse osmosis filter unit 202 and the mineralized filter unit 203 constitute a mineralized water loop 30. That is, the mineralized water loop 30 is connected to the water inlet side of the reverse osmosis filter unit 202 through the pre-filter unit 201, connected to the pure water side of the reverse osmosis filter unit 202 through the mineralized filter unit 203, and connected to the water inlet side of the pre-filter unit 201 through the mineralized filter unit 203. Correspondingly, the mineralized water reflux process is as follows: after the raw water passes through the water inlet pipe 10, it first passes through the pre-filter unit 201 for preliminary filtration, then enters the water inlet side of the reverse osmosis filter unit 202 under the action of the water pump 204, is subjected to water purification filtration treatment through the reverse osmosis filter unit 202, and then is subjected to mineralization filtration treatment through the mineralized filter unit 203, and finally the mineralized water obtained after mineralization flows back to the pre-filter unit 201.

[0035] In one embodiment, a mineralized water control valve 50 is provided in the mineralized water circuit 30. By opening and closing the mineralized water control valve 50, the connection and disconnection of the mineralized water circuit 30 can be controlled. When the mineralized water control valve 50 is closed, the mineralized water circuit 30 is in a disconnected state, and the mineralized water flowing out of the mineralized filter unit 203 is directly discharged through the water outlet pipe, providing mineralized water for drinking to the user. When the water intake is stopped and the mineralized water control valve 50 is opened after a certain volume / time of water production, the mineralized water circuit 30 is in a connected state, thereby starting the mineralized water reflux mode, and the mineralized water flowing out of the mineralized filter element unit 203 flows back to the water inlet side of the pre-filter element unit 201, and is mixed with the raw water flowing out of the water inlet pipe 10 in a certain proportion, and the mixed water flows into the reverse osmosis filter element unit 202 to flush the reverse osmosis membrane, so that the reverse osmosis membrane is flushed and soaked with water with lower TDS, so that the concentration of the first cup of water next time will be lower than the previous concentration, providing better TDS buffering capacity for the next water intake, thereby solving the problem of high TDS value of the first cup of water and reducing the TDS value of short-frequency water intake. In addition, the water pump 204 can provide sufficient pressure for the reverse osmosis filter element unit 202, so that the filter membrane of the reverse osmosis filter element unit 202 is flushed more fully.

[0036] See also Figure 2As shown, the mineralized water circuit 30 includes a first mineralized water branch 31 and a second mineralized water branch 32 .

[0037] Among them, the first mineralized water loop 31 is connected to the water outlet side of the mineralized filter unit 203, and is used to directly discharge the mineralized water flowing out of the mineralized filter unit 203 to provide mineralized water for drinking for users. The second mineralized water loop 32 is respectively connected to one side of the first mineralized water branch 31, the water outlet side of the mineralized filter unit 203, the water outlet side of the water inlet pipe 10, and the water inlet side of the pre-filter 201. When the mineralized water reflux mode is turned on, the second mineralized water loop 32 returns the mineralized water flowing out of the water outlet side of the mineralized filter unit 203 to the water inlet side of the pre-filter 201, and mixes it with the raw water flowing out of the water outlet side of the water inlet pipe 10, and flows the mixed water into the reverse osmosis filter 202 to flush the reverse osmosis membrane, so that the reverse osmosis membrane is flushed and soaked with water with lower TDS, so the concentration of the first cup of water next time will be lower, providing better TDS buffering capacity for the next water intake.

[0038] In one embodiment, the first mineralized water branch 31 includes: a first one-way valve 310 and a first switch valve 312 .

[0039] The water inlet side of the first one-way valve 310 is communicated with the water outlet side of the mineralized filter element unit 203, and the water inlet side of the first switch valve 312 is communicated with the water outlet side of the first one-way valve 310. By controlling the first switch valve 312 to be open, the mineralized water flowing out of the water outlet side of the mineralized filter element unit 203 can be used as a drinking water outlet for users to drink.

[0040] In one embodiment, the second mineralized water branch 32 includes: a second one-way valve 320 and a second switch valve 322, the water inlet side of the second switch valve 322 is respectively connected to the water inlet side of the first one-way valve 310 of the first mineralized water branch 31 and the water outlet side of the mineralized filter element unit 203, the water outlet side of the second switch valve 322 is connected to the water inlet side of the second one-way valve 320, the water outlet side of the second one-way valve 320 is connected to the water inlet side of the pre-filter element 201, and the water outlet side of the second one-way valve 320 is connected to the pre-filter element unit 201. The mineralized water flowing out of the mineralized filter element unit 203 flows into the water inlet side of the pre-filter element 203 through the second switch valve 322 and the second one-way valve 320 in the second mineralized water branch, so that the mineralized water is returned to the pre-filter element 201 and mixed with the tap water flowing out of the water inlet pipe 10 in a certain proportion, so that the mixed water flows into the reverse osmosis filter element 202 to flush the reverse osmosis membrane.

[0041] In this embodiment, the pure water flowing out of the pure water side of the reverse osmosis filter unit 202 is refluxed to the pre-filter unit 201 through the mineralized filter unit 203 through the mineralized filter unit 203 through the mineralized water loop 30, mixed with tap water in a certain proportion, and enters the flushing filter membrane of the reverse osmosis filter unit 202 for a period of time. At this time, the reverse osmosis membrane is flushed and soaked by water with lower TDS, so the concentration of the first cup of water next time will be relatively low, and because the water inlet concentration of the membrane is low, the water concentration in the mineralized filter unit is even lower, and the next water intake will have better TDS buffering capacity, thereby achieving the purpose of reducing the TDS of the first cup of water for the next water intake, and effectively solving the problem of high TDS value of the first cup of water next time.

[0042] See also Figure 4 As shown, the mineralized water system 1 further includes: a first water quality detector 130 and a second water quality detector 132 .

[0043] The first water quality detector 130 can be arranged at the water inlet of the mineralized filter unit 203. In an optional embodiment, the first water quality detector is arranged on the water inlet pipeline 109 of the mineralized filter unit 203, and is used to detect the first water quality parameter of the upstream 50 of the mineralized filter unit. The second water quality detector 132 can be arranged at the water outlet of the mineralized filter unit 203. In an optional embodiment, the second water quality detector 132 is arranged on the water outlet pipeline 60 of the mineralized filter unit 203, and is used to detect the second water quality parameter of the downstream of the mineralized filter unit.

[0044] The water quality detector (the first water quality detector 130 and the second water quality detector 132) can be a total dissolved solids (TDS) detector or a conductivity meter. When the first water quality detector 130 and the second water quality detector 132 are TDS detectors, the first water quality parameter is the first TDS value and the first water quality parameter is the second TDS value. When the first water quality detector 130 and the second water quality detector 132 are conductivity meters, the first water quality parameter is the first conductivity value and the first water quality parameter is the second conductivity value.

[0045] The total dissolved solids (TDS) value refers to the total amount of solids dissolved in water, including both inorganic and organic matter. The unit of measurement is milligrams per liter (1 mg / L = 1 ppm), indicating how many milligrams of total dissolved solids are dissolved in 1 liter of water. The higher the TDS value, the more dissolved matter is contained in the water. Generally, the conductivity value can be used to roughly understand the salt content in the solution. The higher the conductivity, the higher the salt content and the higher the TDS value. The higher the conductivity, the higher the ion concentration in the water, which may contain more dissolved substances.

[0046] In one embodiment, the first water quality detector 130 and the second water quality detector 132 are electrically connected to the controller respectively, the first water quality detector 130 transmits the detected first water quality parameter to the controller, and the second water quality detector 130 transmits the detected second water quality parameter to the controller.

[0047] After obtaining the first water quality parameter and the second water quality parameter, the controller can calculate the water quality PH value according to the second water quality parameter and the first water quality parameter, thereby controlling the opening or closing of the mineralized water control valve 50 according to the water quality PH value, and further controlling the on-off of the mineralized water circuit 30. Specifically, the controller determines whether the water quality PH value is higher than a preset PH threshold value. When the controller determines that the water quality PH value is higher than the preset PH threshold value, the mineralized water control valve 50 can be controlled to be closed, so that the mineralized water circuit 30 is in a disconnected state. When the controller determines that the water quality PH value is lower than the preset PH threshold value, the mineralized water control valve 50 can be controlled to be opened, so that the mineralized water circuit 30 is in a connected state.

[0048] In one embodiment, the controller calculates the water quality parameter difference according to the second water quality parameter and the first water quality parameter, and according to the preset correspondence between the water quality parameter difference and the water quality pH value, the water quality pH value filtered out by the mineralized filter element unit 203 can be obtained. The correspondence is a mathematical function obtained by fitting the relationship between the water quality parameter difference and the pH value using a data fitting method (such as linear regression, polynomial regression, machine learning algorithm, etc.).

[0049] See also Figure 3 and Figure 4 As shown, the water inlet pipe 10 is provided with a flow control unit 205 for adjusting and controlling the water flow entering the mineralized water system 1 .

[0050] In one embodiment, the flow control unit 205 may include a valve, a flow meter, a regulator, etc. to achieve precise flow control.

[0051] According to the difference between the first water quality parameter and the second water quality parameter, the flow rate of the flow control unit 205 is different. In specific applications, the controller calculates the water quality PH value according to the difference between the first water quality parameter and the second water quality parameter, and controls the flow rate of the flow control unit 205 to be different according to the different water quality PH values.

[0052] For example, if the pH value of the water quality is lower than the preset first threshold value, or higher than the preset second threshold value, that is, the water quality is too acidic or too alkaline, the controller can control the flow control unit 205 to reduce or increase the flow rate to optimize the mineralization treatment effect of the mineralization filter unit 203. According to the decision of the controller, the flow control unit 205 adjusts its opening or working mode, thereby changing the water flow entering the mineralization waterway system 1. This adjustment can be continuous or graded.

[0053] By precisely controlling the flow rate, you can ensure that the water quality maintains the optimal pH range during the treatment process, thereby improving the treatment effect. Avoid damage to the equipment caused by over-acidic or over-alkaline water quality and extend the life of the equipment. By optimizing flow control, you can reduce unnecessary energy consumption and water waste. Figure 5 As shown, the mineralized filter element unit 203 includes: a mineralized pipeline 901 , on which a mineralized filter element 9010 is arranged.

[0054] The mineralized pipeline 901 is a channel through which water flows, and is used to ensure that the water flows smoothly and efficiently without introducing any pollutants.

[0055] The mineralization filter element 9010 is responsible for adding beneficial minerals to the water flow to enhance the taste and nutritional value of the water. The mineralization filter element 9010 may be made of a variety of materials, including but not limited to medical stone, tourmaline, weak alkaline mineralization balls, etc.

[0056] In actual application, when the pure water flowing out of the reverse osmosis filter unit 202 passes through the mineralization filter unit 203, the pure water first enters the mineralization pipeline 901 and then flows through the mineralization filter 9010. The water flows in contact with and exchanges with the materials in the mineralization filter 9010, thereby absorbing beneficial minerals. After the mineralization treatment, the taste and nutritional value of the water are improved, making it more suitable for drinking.

[0057] See also Figure 6 As shown, the mineralized filter element unit 203 includes: a mineralized pipeline 101 and a suppression pipeline 102 . The mineralized pipeline 101 is provided with a mineralized filter element 103 , and the suppression pipeline 102 is provided with a suppression filter element 104 .

[0058] In an optional embodiment, the mineralization pipeline 101 and the suppression pipeline 102 are arranged in parallel and can discharge water at the same time. Specifically, the mineralization pipeline 101 and the suppression pipeline 102 are connected in parallel between the water inlet pipeline 109 of the mineralization filter element unit 203 and the water outlet pipeline 60 of the mineralization filter element unit 203. The water inlet pipeline 109 can be connected to the mineralization pipeline 101 and the suppression pipeline 102 through a three-way valve or a diverter valve, and the mineralization pipeline 101 and the suppression pipeline 102 can be connected to the water outlet pipeline 60 through a three-way valve. When the mineralization pipeline 101 and the suppression pipeline 102 discharge water at the same time, the water outlets of the mineralization pipeline 101 and the suppression pipeline 102 can be mixed and discharged through the water outlet pipeline 60.

[0059] By arranging the mineralization filter element 103 in the mineralization pipeline 101, the mineralization filter element 103 can release (dissolve) minerals into the water body flowing through, so that the water body output by the mineralization pipeline 101 contains minerals, so as to meet people's requirements for mineralized drinking water. By arranging the inhibition filter element 104 in the inhibition pipeline 102, the inhibition filter element 104 can release inhibition substances into the water body flowing through. When the water body containing inhibition substances flows through the mineralization filter element 103, the dissolution of minerals in the mineralization filter element 103 can be inhibited, so as to avoid the situation where the mineral content in the water body is too high.

[0060] In an optional embodiment, the mineralized filter element unit 203 further includes: a series switching pipeline 105. The series switching pipeline 105 is arranged between the mineralized pipeline 101 and the suppression pipeline 102, and is used to connect the suppression filter element 104 and the mineralized filter element 103 in series. The output side of the series switching pipeline 105 is connected to the mineralized pipeline 101 or the mineralized filter element 103, and the input side of the series switching pipeline 105 is connected to the suppression pipeline 102 or the suppression filter element 104.

[0061] By connecting the output side of the series switching pipeline 105 to the mineralization pipeline 101 or the mineralization filter element 103, and connecting the input side of the series switching pipeline 105 to the suppression pipeline 102 or the suppression filter element 104, a mineralization treatment structure can be formed in which the suppression filter element 104 is located upstream and the mineralization filter element 103 is located downstream, and water containing the inhibition substance flows through the water path of the mineralization filter element 103.

[0062] In specific implementation, in order to prevent the mineral content in the water body from being too high, the series switching pipeline 105 can be used to allow the water containing the inhibitory substance to flow through the mineralized filter element 103, so as to inhibit the mineralized filter element 103 from releasing minerals, thereby achieving the requirement of reducing the mineral content in the water body. When the mineralized filter element 103 is in an immersed state, for example, the water flow rate in the mineralized pipeline 101 is too slow, the water is stopped, or the water is stopped for a set period of time, which may cause the mineral content in the water body (especially in the mineralized filter element 103) to be too high. By switching the pipeline 105 in series, the water containing the inhibitory substance enters the mineralized filter element 103, thereby inhibiting the mineralized filter element 103 in an immersed state from releasing minerals, thereby avoiding excessively high mineral content in the water body. The immersed state described in this embodiment refers to the situation where the flow rate in the filter element is less than the design threshold, including the situation where the water body stops flowing or flows slowly.

[0063] In an optional embodiment, a first control valve 106 is provided on the series switching pipeline 105 .

[0064] The first control valve 106 has a state where water can flow through and a state where water cannot flow through. In a specific application, the first control valve 106 can also be a flow valve. By arranging the first control valve 106 on the series switching pipeline 105, it is possible to control whether water can flow from the suppression filter element 104 to the mineralization filter element 103 through the series switching pipeline 105. For example, when the mineralized filter element 103 is in an immersed state, the first control valve 106 can be placed in a state where water can pass through. Therefore, the water can flow from the suppression filter element 104 to the mineralized filter element 103 through the series switching pipeline 105, thereby suppressing the release of minerals from the mineralized filter element 103 to reduce the mineral content in the water body and prevent the mineral content from exceeding the set standard, thereby controlling the mineral content within a safe standard range; when the water flow rate of the mineralized pipeline 101 exceeds the set flow rate, the concentration of mineralized substances in the water flowing through the mineralized filter element 103 at this time will not exceed the set standard, and there is no need to reduce the mineral content in the water body, so the first control valve 106 can be placed in a state where water cannot pass through.

[0065] In an optional embodiment, the mineralized filter element unit 203 further includes: a second control valve 107 , which is disposed in the mineralized pipeline 101 and located at the upstream side of the mineralized filter element 103 .

[0066] The second control valve 107 is used to control the on / off and / or flow rate of the mineralization pipeline 101. By controlling the second control valve 107 to be open or closed, it can be realized whether water is delivered to the mineralization filter element 103. By controlling the flow rate of the mineralization pipeline 101 by the second control valve 107, the amount of minerals released by the mineralization filter element 103 in a unit volume of water can be controlled. Specifically, when the water flow rate of the mineralization pipeline 101 is greater than the set flow rate, the mineral content in the unit volume of water will decrease, and when the water flow rate of the mineralization pipeline 101 is lower than the set flow rate, the mineral content in the unit volume of water will increase. Therefore, the flow rate of the mineralization pipeline 101 can be adjusted by the second control valve 107, thereby adjusting the content of minerals in the water of the mineralization pipeline 101.

[0067] The output side of the series switching pipeline 105 is connected between the second control valve 107 and the mineralized filter element 103. In this way, the output side of the series switching pipeline 105 is connected to the upstream side of the mineralized filter element 103, so that the water in the series switching pipeline 105 can flow to the mineralized filter element 103.

[0068] In an optional embodiment, the mineralized filter element unit 203 further includes: a third control valve 108 , which is disposed in the suppression pipeline 102 and located at the downstream side of the suppression filter element 104 .

[0069] The third control valve 108 is used to control the on-off and / or flow rate of the suppression pipeline 102. The input side of the series switching pipeline 105 is connected between the suppression filter element 104 and the third control valve 108. In this way, the input side of the series switching pipeline 105 is connected to the downstream side of the suppression filter element 104. When the third control valve 108 is closed and the first control valve 106 is opened, the water containing the inhibition substance can flow to the series switching pipeline 105, and then the water containing the inhibition substance can flow to the mineralization filter element 103.

[0070] By controlling the opening or closing of the second control valve 107 and the third control valve 108, and controlling whether the water flow of the first control valve 106 can pass through, it is possible to achieve simultaneous or separate water discharge from the mineralization pipeline 101 and the suppression pipeline 102, and the water flow flowing through the suppression filter element 104 can enter the mineralization filter element 113 through the series switching pipeline 115.

[0071] For example, when the mineralization pipeline 101 and the suppression pipeline 102 need to discharge water at the same time, the second control valve 107 and the third control valve 108 can be controlled to open, and the first control valve 106 can be closed. At this time, the series switching pipeline 105 is disconnected, the mineralization pipeline 101 and the suppression pipeline 102 are in a parallel state, and the water containing minerals in the mineralization pipeline 101 and the water containing inhibitors in the suppression pipeline 102 can be mixed in the water outlet pipeline 60 and then discharged.

[0072] For another example, when the mineralization pipeline 101 needs to discharge water alone, the second control valve 107 can be controlled to open, and the first control valve 106 and the third control valve 108 can be closed. At this time, the mineralization pipeline 101 is connected, the inhibition pipeline 102 and the series switching pipeline 105 are both disconnected, and the mineral-containing water in the mineralization pipeline 101 can be discharged through the water outlet pipeline 60.

[0073] For another example, when the mineralized filter element 103 is in an immersed state, the second control valve 107 and the third control valve 108 can be controlled to be closed, and the first control valve 106 can be opened. At this time, the inhibition filter element 104 and the mineralized filter element 103 are connected through the series switching pipeline 105, and the water containing the inhibitory substance can flow to the mineralized filter element 103 through the series switching pipeline 105.

[0074] In an optional embodiment, the first control valve 106, the second control valve 107 and the third control valve 108 are all solenoid valves. Of course, in other embodiments, the first control valve 106, the second control valve 107 and the third control valve 108 may also be other valves.

[0075] In an optional embodiment, the mineralized filter element 103 includes a zinc-containing filter material (e.g., smithsonite, hydrozincite), and the suppression filter element 104 includes an alkaline filter material (e.g., magnesite, brucite, sepiolite, calcite). Zinc is indispensable for cell replication, immune activity, tissue repair and growth, and is a key element for growth and development, reproductive inheritance, immune system and bone metabolism. Therefore, by setting the mineralized filter element 103 to include a zinc-containing filter material, releasing mineral zinc into the water body is beneficial to people's health. In addition, water quality with a pH value between 7.0 and 9.0 is the best water quality suitable for human health. By setting the suppression filter element 104 to include an alkaline filter material, it is beneficial to keep the water quality in the pH range of 7.0 to 9.0.

[0076] It should be noted that although zinc is one of the essential trace elements for the human body, it contributes to the growth and development of the human body and can also participate in the metabolism of vitamins. However, when the zinc content in drinking water exceeds the standard, the zinc intake of the human body may exceed the standard, which may cause some harm to the human body, such as zinc poisoning, abnormal lipid metabolism, etc. Therefore, by setting the suppression filter 104 to suppress the excessive release of zinc, the occurrence of excessive zinc concentration can be avoided.

[0077] It is understood that in other embodiments, the mineralized filter element 103 may also include filter materials containing other minerals, such as copper, calcium, magnesium, potassium, strontium, etc. It should be noted that when the mineralized filter element 103 includes filter materials containing other minerals, the suppression filter element 104 may be matched with corresponding suppression filter materials.

[0078] In an optional embodiment, the mineralization filter element 103 includes a first alkaline filter material, and the suppression filter element 104 includes a second alkaline filter material, the alkalinity of the first alkaline filter material is weaker than the alkalinity of the second alkaline filter material, and the alkalinity of the second alkaline filter material is stronger than the alkalinity of the first alkaline filter material, so the second alkaline filter material can be used to inhibit the dissolution of alkaline substances in the first alkaline filter material. Exemplarily, the first alkaline filter material (weak alkalinity) is filled with medical stone or tourmaline, and the second alkaline filter material (strong alkalinity) is filled with high concentrations of zinc and magnesium.

[0079] By installing weak alkaline ore in the first alkaline filter material and strong alkaline ore in the second alkaline filter material, when the water flows through the first alkaline filter material first, the alkaline substances precipitated from the first alkaline filter material will increase the pH value of the water. Subsequently, when the water flows into the suppression filter element 104, since the pH value of the water has been increased by the first alkaline filter material at this time, the precipitation of minerals such as zinc and copper in the second alkaline filter material in the water will be inhibited to a certain extent (usually because the solubility of these minerals at higher pH values ​​is reduced or the precipitation rate is slowed down).

[0080] By adopting the filter element unit 50, when the mineral content in the water body is too high, the release or dissolution of the minerals in the mineralization filter element can be suppressed by the suppression filter element, so as to reduce the mineral content in the water body.

[0081] See also Figure 7 As shown, the mineralization filter element unit 203 includes: a mineralization pipeline 111 and a promotion pipeline 112 , the mineralization pipeline 111 is provided with a mineralization filter element 113 , and the promotion pipeline 112 is provided with a promotion filter element 114 .

[0082] In an optional embodiment, the mineralization pipeline 111 and the promotion pipeline 112 are arranged in parallel and can discharge water at the same time. Specifically, the mineralization pipeline 111 and the promotion pipeline 112 are connected in parallel between the water inlet pipeline 109 of the mineralization filter element unit 203 and the water outlet pipeline 60 of the mineralization filter element unit 203. The water inlet pipeline 109 can be connected to the mineralization pipeline 111 and the promotion pipeline 112 through a three-way valve or a diverter valve, and the mineralization pipeline 111 and the promotion pipeline 112 can be connected to the water outlet pipeline 60 through a three-way valve. When the mineralization pipeline 111 and the promotion pipeline 112 discharge water at the same time, the water discharged from the mineralization pipeline 111 and the promotion pipeline 112 can be mixed and discharged through the water outlet pipeline 60.

[0083] By arranging the mineralization filter element 113 in the mineralization pipeline 111, the mineralization filter element 113 can release (dissolve) minerals into the water body flowing through, so that the water body output by the mineralization pipeline 111 contains minerals, so as to meet people's requirements for mineralized drinking water. By arranging the promotion filter element 114 in the promotion pipeline 112, the promotion filter element 114 can release the promotion substance into the water body flowing through. When the water body containing the promotion substance flows through the mineralization filter element 113, the dissolution of minerals in the mineralization filter element 113 can be promoted, so as to increase the mineral content in the water body.

[0084] In an optional embodiment, the mineralization filter element unit 203 further includes: a series switching pipeline 115. The series switching pipeline 115 is arranged between the mineralization pipeline 111 and the promotion pipeline 112, and is used to connect the promotion filter element 114 and the mineralization filter element 113 in series. The output side of the series switching pipeline 115 is connected to the mineralization pipeline 111 or the mineralization filter element 113, and the input side of the series switching pipeline 115 is connected to the promotion pipeline 112 or the promotion filter element 114.

[0085] By connecting the output side of the series switching pipeline 115 to the mineralization pipeline 111 or the mineralization filter element 113, and connecting the input side of the series switching pipeline 115 to the promotion pipeline 112 or the promotion filter element 114, a mineralization treatment structure can be formed in which the promotion filter element 114 is located upstream and the mineralization filter element 113 is located downstream, and water containing the promoting substance flows through the water path of the mineralization filter element 113.

[0086] By allowing the water containing the promoting substance to flow into the mineralized filter element 113, the promoting substance can promote the mineralized filter element 113 to release minerals, increase the content of minerals in the water, and thus avoid the situation where the content of minerals in the water does not meet the standard. For example, when the water flow rate of the mineralized pipeline 111 exceeds the set flow rate (i.e., the water flow rate is a large flow rate), the water flow rate is accelerated, and the amount of minerals released per unit volume of water will decrease. By switching the pipeline 115 in series to allow the water containing the promoting substance to flow into the mineralized filter element 113, the mineralized filter element 113 is promoted to release minerals, which can increase the content of minerals in the water. When the mineralized filter element 113 has been used for a certain period of time and reaches the middle and late stages of its service life, the performance of the mineralized filter element 113 in releasing minerals decreases. By promoting the mineralized filter element 113 to release minerals by promoting the promoting substance, the mineral content in the water can be effectively increased, so that the minerals in the water can meet the standard and the service life of the mineralized filter element 113 is extended.

[0087] In an optional embodiment, a first control valve 116 is provided on the series switching pipeline 115 .

[0088] The first control valve 116 has a state where water can flow through and a state where water cannot flow through. In a specific application, the first control valve 116 can also be a flow valve. By arranging the first control valve 116 on the series switching pipeline 115, it is possible to control whether water can flow from the promotion filter element 114 to the mineralization filter element 113 through the series switching pipeline 115. When the water flow rate of the mineralization pipeline 111 is large, or the mineralization filter element 113 has reached the middle and late stages of its service life, the first control valve 116 can be placed in a state where water can pass through. At this time, the water can flow from the promotion filter element 114 to the mineralization filter element 113 through the series switching pipeline 115, thereby increasing the amount of minerals released by the mineralization filter element 113 to increase the content of minerals in the water and prevent the content of minerals from being lower than the set standard, thereby controlling the content of minerals within a safe standard range; when the water flow rate of the mineralization pipeline 111 is lower than the set flow rate, or the mineralization filter element 113 is in the early stages of its service life, the concentration of mineralized substances in the water flowing through the mineralization filter element 113 will not be lower than the set standard, and the content of minerals in the water will meet the standard, so the first control valve 116 can be placed in a state where water cannot pass through.

[0089] In an optional embodiment, the mineralized filter element unit 203 further includes: a second control valve 117 , which is disposed in the mineralized pipeline 111 and located at the upstream side of the mineralized filter element 113 .

[0090] The second control valve 117 is used to control the on-off and / or flow rate of the mineralization pipeline 111. By controlling the second control valve 117 to be opened or closed, it can be realized whether water is delivered to the mineralization filter element 113. By controlling the flow rate of the mineralization pipeline 111 by the second control valve 117, the amount of minerals released by the mineralization filter element 113 in a unit volume of water can be controlled. Specifically, when the water flow rate of the mineralization pipeline 111 is greater than the set flow rate, the mineral content in the unit volume of water will decrease, and when the water flow rate of the mineralization pipeline 111 is lower than the set flow rate, the mineral content in the unit volume of water will increase. Therefore, the flow rate of the mineralization pipeline 111 can be adjusted by the second control valve 117, thereby adjusting the content of minerals in the water of the mineralization pipeline 111.

[0091] The output side of the series switching pipeline 115 is connected between the second control valve 117 and the mineralized filter element 113. In this way, the output side of the series switching pipeline 115 is connected to the upstream side of the mineralized filter element 113, so that the water in the series switching pipeline 115 can flow to the mineralized filter element 113.

[0092] In an optional embodiment, the mineralization filter element unit 203 further includes: a third control valve 118 , which is disposed in the promotion pipeline 112 and located at the downstream side of the promotion filter element 114 .

[0093] The third control valve 118 is used to control the on-off and / or flow rate of the promotion pipeline 112. The input side of the series switching pipeline 115 is connected between the promotion filter element 114 and the third control valve 118. In this way, the input side of the series switching pipeline 115 is connected to the downstream side of the promotion filter element 114. When the third control valve 118 is closed and the first control valve 116 is opened, the water containing the promotion substance can flow to the series switching pipeline 115, and then the water containing the promotion substance flows to the mineralization filter element 113.

[0094] By controlling the opening or closing of the second control valve 117 and the third control valve 118, and controlling whether the water flow of the first control valve 116 can pass through, it is possible to achieve simultaneous or separate water discharge from the mineralization pipeline 111 and the promotion pipeline 112, and the water flow flowing through the promotion filter element 114 can enter the mineralization filter element 113 through the series switching pipeline 115.

[0095] For example, when the mineralization pipeline 111 and the promotion pipeline 112 need to discharge water at the same time, the second control valve 117 and the third control valve 118 can be controlled to open, and the first control valve 116 can be closed. At this time, the series switching pipeline 115 is disconnected, the mineralization pipeline 111 and the promotion pipeline 112 are in a parallel state, and the water containing minerals in the mineralization pipeline 111 and the water containing the promotion substance in the promotion pipeline 112 can be mixed in the water outlet pipeline 60 and then discharged.

[0096] For another example, when the mineralization pipeline 111 needs to discharge water alone, the second control valve 117 can be controlled to open, and the first control valve 116 and the third control valve 118 can be closed. At this time, the mineralization pipeline 111 is turned on, and the promotion pipeline 112 and the series switching pipeline 115 are both disconnected, and the mineral-containing water in the mineralization pipeline 111 can be discharged through the water outlet pipeline 60.

[0097] For another example, when the mineralized filter element 113 is in the middle and late stages of its service life, the first control valve 116 can be controlled to open, and the second control valve 117 and the third control valve 118 can be closed. At this time, the filter element 114 and the mineralized filter element 113 are connected through the series switching pipeline 115, and the water containing the promoting substance can flow to the mineralized filter element 113 through the series switching pipeline 115, thereby promoting the mineralized filter element 113 to release minerals, so that the minerals in the water can meet the standards. Even if the mineralized filter element 113 is in the middle and late stages of its service life (the mineral dissolution rate decreases), by setting the promoting filter element 114, the mineral dissolution rate in the mineralized filter element 113 is kept within the set range, and the service life of the mineralized filter element 113 can be prolonged. Alternatively, when the flow rate is large, the first control valve 116 can be controlled to open, and the second control valve 117 and the third control valve 118 can be closed, so that the minerals in the water can meet the standards at a large flow rate.

[0098] In an optional embodiment, the first control valve 116, the second control valve 117 and the third control valve 118 are all solenoid valves. Of course, in other embodiments, the first control valve 116, the second control valve 117 and the third control valve 118 may also be other valves.

[0099] In an optional embodiment, the mineralized filter element 113 includes a filter material containing metasilicic acid, and the promoting filter element 114 includes an alkaline filter material. Silicon is one of the essential trace elements for the human body, and silicon in the human body tends to decrease significantly with age. Modern medicine shows that silicon affects the biological synthesis of bone tissue, is related to bone growth and structure, has a physiological role in the process of bone calcification, can promote bone development, and insufficient intake will reduce the calcium content of bones. Lack of silicon in the body can also lead to growth retardation, bone abnormalities, deformities (especially the head), and poor development of teeth or enamel. Silicon can also enhance the strength of elastic fibers in blood vessels, especially the elastic layer of the inner membrane, thereby forming a barrier to effectively hinder lipid invasion. This property makes silicon have an anti-atherosclerotic effect, which can maintain the integrity of elastic fibers and interstitium, thereby preventing the formation of atherosclerotic plaques. Silicon can also remove fat deposited on the inner wall of blood vessels. This mechanism can alleviate arteriosclerosis, cardiovascular and heart diseases.

[0100] Silicon needed by the human body generally comes from water, and the silicon in the water is in the form of metasilicic acid, which is easily absorbed by the human body and skin. Therefore, by setting the mineralized filter element 113 to include a filter material containing metasilicic acid, the mineralized filter element 113 can release metasilicic acid into the water body, which is beneficial to human health.

[0101] In addition, water quality with a pH value between 7.0 and 9.0 is the best water quality suitable for human health. By setting the promotion filter element 114 to include alkaline filter materials, it is helpful to keep the water quality within the pH range of 7.0 to 9.0, which is beneficial to human health.

[0102] It is understood that in other embodiments, the mineralized filter element 113 may also include filter materials containing other minerals, such as copper, calcium, magnesium, potassium, strontium, zinc, etc. It should be noted that when the mineralized filter element 113 includes filter materials containing other minerals, the corresponding promoting filter materials can be matched in the promoting filter element 114.

[0103] In an optional embodiment, the mineralized filter element 113 includes medical stone, and the promoting filter element 114 includes periclase. By using medical stone as the filter material of the mineralized filter element 113, both metasilicic acid beneficial to the human body can be released and substances harmful to the human body will not be produced.

[0104] By adopting the filter element unit 50, when the mineral content in the water body is insufficient, the filter element can be used to promote the release or dissolution of minerals in the mineralization filter element, so as to increase the mineral content in the water body.

[0105] See also Figure 8 As shown, the mineralization filter element unit 203 includes: a mineralization pipeline 121, a suppression pipeline 122 and a promotion pipeline 123. The mineralization pipeline 121 is provided with a mineralization filter element 124, the suppression pipeline 122 is provided with a suppression filter element 125, and the promotion pipeline 123 is provided with a promotion filter element 126.

[0106] In an optional embodiment, the mineralization pipeline 121, the suppression pipeline 122 and the promotion pipeline 123 are arranged in parallel and can discharge water at the same time. Specifically, the mineralization pipeline 121, the suppression pipeline 122 and the promotion pipeline 123 are connected in parallel between the water inlet pipeline 109 of the mineralization filter element unit 203 and the water outlet pipeline 60 of the mineralization filter element unit 203. The water inlet pipeline 109 can be connected to the mineralization pipeline 121, the suppression pipeline 122 and the promotion pipeline 123 through a multi-way valve or a diverter valve, and the mineralization pipeline 121, the suppression pipeline 122 and the promotion pipeline 123 can be connected to the water outlet pipeline 60 through a multi-way valve. When the mineralization pipeline 121, the suppression pipeline 122 and the promotion pipeline 123 discharge water at the same time, the water outlets of the mineralization pipeline 121, the suppression pipeline 122 and the promotion pipeline 123 can be mixed and discharged through the water outlet pipeline 60.

[0107] By setting the mineralization filter element 124 in the mineralization pipeline 121, the mineralization filter element 124 can release (dissolve) minerals into the water body flowing through, so that the water body output by the mineralization pipeline 121 contains minerals to meet people's requirements for mineralized drinking water. By setting the inhibition filter element 125 in the inhibition pipeline 122, the inhibition filter element 125 can release inhibition substances into the water body flowing through. When the water body containing inhibition substances flows through the mineralization filter element 124, the dissolution of minerals in the mineralization filter element 124 can be inhibited, thereby avoiding the situation where the mineral content in the water body is too high. By setting the promotion filter element 126 in the promotion pipeline 123, the promotion filter element 126 can release promotion substances into the water body flowing through. When the water body containing promotion substances flows through the mineralization filter element 124, the dissolution of minerals in the mineralization filter element 124 can be promoted, thereby increasing the mineral content in the water body.

[0108] In an optional embodiment, the mineralized filter element unit 203 further includes: a first connecting pipeline 127. The first connecting pipeline 127 is disposed between the mineralized pipeline 121 and the suppression pipeline 122, and is used to connect the suppression filter element 125 and the mineralized filter element 124 in series. The output side of the first connecting pipeline 127 is connected to the mineralized pipeline 121 or the mineralized filter element 124, and the input side of the first connecting pipeline 127 is connected to the suppression pipeline 122 or the suppression filter element 125. In this way, a mineralized treatment structure can be formed in which the suppression filter element 125 is located upstream and the mineralized filter element 124 is located downstream, and the water containing the inhibition substance flows through the water path of the mineralized filter element 124.

[0109] In an optional embodiment, the mineralization filter element unit 203 further includes: a second connecting pipeline 128. The second connecting pipeline 128 is arranged between the mineralization pipeline 121 and the promotion pipeline 123, and is used to connect the promotion filter element 126 and the mineralization filter element 124 in series. The output side of the first connecting pipeline 127 is connected to the mineralization pipeline 121 or the mineralization filter element 124, and the input side of the first connecting pipeline 127 is connected to the promotion pipeline 123 or the promotion filter element 126. In this way, a mineralization treatment structure can be formed in which the promotion filter element 126 is located upstream and the mineralization filter element 124 is located downstream, and the water containing the promotion substance flows through the water path of the mineralization filter element 124.

[0110] In an optional embodiment, a first control valve 1291 is provided on the first connecting pipeline 127. The first control valve 1291 has a state where water can flow through and a state where water cannot flow through. In a specific application, the first control valve 1291 may also be a flow valve.

[0111] In an optional embodiment, a second control valve 1292 is disposed on the second connecting pipeline 128. The second control valve 1292 has a state where water can flow through and a state where water cannot flow through. In a specific application, the second control valve 1292 can also be a flow valve.

[0112] In an optional embodiment, the mineralization pipeline 121 is provided with a third control valve 1293 for controlling the on-off and / or flow rate of the mineralization pipeline 121. The third control valve 1293 is provided on the upstream side of the mineralization filter element 124.

[0113] In an optional embodiment, the suppression pipeline 122 is provided with a fourth control valve 1294 for controlling the on-off and / or flow rate of the suppression pipeline 122. The fourth control valve 1294 is provided on the downstream side of the suppression filter element 125, and by controlling the opening or closing of the fourth control valve 1294, it can be realized whether water is delivered to the suppression filter element 125.

[0114] In an optional embodiment, the promotion pipeline 123 is provided with a fifth control valve 1295 for controlling the on-off and / or flow rate of the promotion pipeline 123. The fifth control valve 1295 is provided on the downstream side of the promotion filter element 126, and by controlling the opening or closing of the fifth control valve 1295, it can be realized whether water is delivered to the promotion filter element 126.

[0115] One side of the first connecting line 127 is connected between the third control valve 1293 and the mineralized filter element 124, and the other side of the first connecting line 127 is connected between the suppression filter element 125 and the fourth control valve 1294. Since the third control valve 1293 is arranged on the upstream side of the mineralized filter element 124, and the fourth control valve 1294 is arranged on the downstream side of the suppression filter element 125, the input side of the first connecting line 127 is connected to the downstream side of the suppression filter element 125, and the output side of the first connecting line 127 is connected to the upstream side of the mineralized filter element 124. When the third control valve 1293 and the fourth control valve 1294 are controlled to be closed, and the first control valve 1291 is in a state where water can pass through, the water containing the inhibition substance can flow to the first connecting line 127, and then flow to the mineralized filter element 124.

[0116] One side of the second connecting line 128 is connected between the third control valve 1293 and the mineralization filter element 124, and the other side of the second connecting line 128 is connected between the promoting filter element 126 and the fifth control valve 1295. Since the third control valve 1293 is arranged on the upstream side of the mineralization filter element 124, and the fifth control valve 1295 is arranged on the downstream side of the promoting filter element 126, the input side of the second connecting line 128 is connected to the downstream side of the promoting filter element 126, and the output side of the second connecting line 128 is connected to the upstream side of the mineralization filter element 124. When the third control valve 1293 and the fifth control valve 1295 are controlled to be closed, and the second control valve 1292 is in a state where water can pass through, the water containing the promoting substance can flow to the second connecting line 128, and then flow to the mineralization filter element 124.

[0117] By controlling the opening or closing of the first control valve 1291, the second control valve 1292, the third control valve 1293, the fourth control valve 1294 and the fifth control valve 1295, it is possible to achieve water discharge from at least any two of the mineralization pipeline 121, the suppression pipeline 122 and the promotion pipeline 123 simultaneously or separately, and it is possible that the water flowing through the suppression filter element 125 can enter the mineralization filter element 124 through the first connecting pipeline 127, or that the water flowing through the promotion filter element 126 can enter the mineralization filter element 124 through the second connecting pipeline 128, etc., so that the pipeline structure can meet different requirements.

[0118] For example, when the mineralization pipeline 121, the suppression pipeline 122 and the promotion pipeline 123 need to discharge water at the same time, the third control valve 1293, the fourth control valve 1294 and the fifth control valve 1295 can be controlled to be opened, and the first control valve 1291 and the second control valve 1292 are controlled to be in a state where water cannot flow through. At this time, the first connecting pipeline 127 and the second connecting pipeline 128 are both disconnected, and the mineralization pipeline 121, the suppression pipeline 122 and the promotion pipeline 123 are connected between the water inlet pipeline 109 and the water outlet pipeline 60 and are arranged in parallel. The water in the mineralization pipeline 121, the water in the suppression pipeline 122 and the water in the promotion pipeline 123 are mixed in the water outlet pipeline 60 and then discharged.

[0119] For example, when the mineralized filter element 124 is in a soaking state, the first control valve 1291 can be controlled to be in a state where water can flow through, the second control valve 1292 can be controlled to be in a state where water cannot flow through, and the third control valve 1293, the fourth control valve 1294 and the fifth control valve 1295 can be controlled to be closed. At this time, the second connecting pipeline 128 and the promotion pipeline 123 are both disconnected, the suppression filter element 125 and the mineralized filter element 124 are connected through the first connecting pipeline 127, and the water containing the suppression substance can flow to the mineralized filter element 124 through the first connecting pipeline 127, so that the water containing the suppression substance can enter and fill the mineralized filter element 124, and the mineralized filter element 124 can be soaked by the water containing the suppression substance.

[0120] For example, when preventing the mineral content of the mineralized filter element 124 from exceeding the standard due to immersion and adding new mineral types to the water body, the first control valve 1291 can be controlled to be in a state where water can pass through, the second control valve 1292 can be controlled to be in a state where water cannot pass through, the third control valve 1293 and the fourth control valve 1294 can be controlled to be closed, and the fifth control valve 1295 can be controlled to be opened. At this time, the second connecting pipeline 128 is disconnected; the inhibition filter element 125 and the mineralized filter element 124 are connected through the first connecting pipeline 127, and the water body containing the inhibition substance can flow to the mineralized filter element 124 through the first connecting pipeline 127, thereby inhibiting the mineralized filter element 124 from releasing minerals to prevent the mineral content in the water body from exceeding the standard content; the promotion pipeline 123 is connected, and the water body containing the promotion substance can flow to the water outlet pipeline 60, wherein the promotion filter element 126 may include a filter material that releases minerals, thereby enabling new mineral types to be added to the water body. For example, the promotion filter element 126 includes the periclase filter material described below. The periclase filter material is an alkaline filter material. The released (dissolved) mineral periclase can adjust the pH value of water, improve the taste of drinking water, and maintain the health of the human body.

[0121] For example, when the mineralized filter element 124 is in the middle and late stages of its service life, the first control valve 1291 can be controlled to be in a state where water cannot pass through, the second control valve 1292 can be controlled to be in a state where water can pass through, and the third control valve 1293, the fourth control valve 1294 and the fifth control valve 1295 can be controlled to be closed. At this time, the first connecting line 127 and the suppression line 122 are both disconnected, the promoting filter element 126 and the mineralized filter element 124 are connected through the second connecting line 128, and the water containing the promoting substance can flow to the mineralized filter element 124 through the second connecting line 128, thereby promoting the mineralized filter element 124 to release minerals, so that the minerals in the water can meet the standards. Even if the mineralized filter element 124 is in the middle and late stages of its service life (the mineral dissolution rate decreases), by setting the promoting filter element 126, the mineral dissolution rate in the mineralized filter element 124 is kept within the set range, and the service life of the mineralized filter element 124 can be prolonged. Alternatively, when a large flow rate is expected, the first control valve 1291 can be controlled to be in a state where water cannot flow through, the second control valve 1292 can be controlled to be in a state where water can flow through, and the third control valve 1293, the fourth control valve 1294 and the fifth control valve 1295 can be controlled to be closed, so that the minerals in the water body can meet the standards when the flow rate is large.

[0122] For example, when a large flow is expected and a new type of mineral is added to the water body, the first control valve 1291 can be controlled to be in a state where water cannot pass through, the second control valve 1292 can be controlled to be in a state where water can pass through, the third control valve 1293 and the fifth control valve 1295 can be controlled to be closed, and the fourth control valve 1294 can be controlled to be opened. At this time, the first connecting pipeline 127 is disconnected; the promoting filter element 126 and the mineralizing filter element 124 are connected through the second connecting pipeline 128, and the water body containing the promoting substance can flow to the mineralizing filter element 124 through the second connecting pipeline 128, thereby promoting the mineralizing filter element 124 to release minerals, so that the minerals in the water body can meet the standards; the inhibiting pipeline 122 is connected, and the water body containing the inhibiting substance can flow to the water outlet pipeline 60, wherein the inhibiting filter element 125 may include a filter material that releases minerals, thereby enabling a new type of mineral to be added to the water body. For example, the suppression filter element 125 includes the zeolite filter material described below. The mineral zeolite released (dissolved) by the zeolite filter material can adsorb harmful substances such as heavy metals, ammonium and hydrogen compounds in the water, greatly improving the water quality. In addition, zeolite can also adjust the pH value of water, improve the taste of drinking water, and maintain human health.

[0123] In an optional embodiment, the first control valve 1291, the second control valve 1292, the third control valve 1293, the fourth control valve 1294, and the fifth control valve 1295 are all solenoid valves. Of course, in other embodiments, the first control valve 1291, the second control valve 1292, the third control valve 1293, the fourth control valve 1294, and the fifth control valve 1295 may also be other valves.

[0124] In an optional embodiment, the mineralized filter element 124 includes a filter material containing metasilicic acid, the suppression filter element 125 includes a zeolite filter material, and the promoting filter element 126 includes an alkaline filter material. In other embodiments, the mineralized filter element 124 may also include a filter material containing other minerals, such as copper, calcium, magnesium, potassium, strontium, zinc, etc. It should be noted that when the mineralized filter element 124 includes a filter material containing other minerals, the promoting filter element 126 should be matched with a corresponding promoting filter material, and the suppressing filter element 125 should be matched with a corresponding suppressing filter material.

[0125] In an optional embodiment, the mineralizing filter element 124 includes medical stone, the promoting filter element 126 includes periclase, and the suppressing filter element 125 includes zeolite.

[0126] By adopting the above-mentioned filter element unit 50, by conveying water containing inhibitory substances to the mineralized filter element 124, the release of minerals from the mineralized filter element 124 is inhibited, thereby preventing the occurrence of excessive mineral content in the water; and by conveying water containing promoting substances to the mineralized filter element 124, the release of minerals from the mineralized filter element 124 is promoted, thereby preventing the occurrence of substandard mineral content in the water.

[0127] In some embodiments, the controller can also control the on and off of each control valve in the mineralized filter unit 203 according to the water quality pH value, so as to ensure that the water quality pH value filtered out by the mineralized filter unit 203 is maintained within a preset water quality pH threshold range.
