Description

Technical Field

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

[0002] A mineralizing water purifier is a device that deeply purifies tap water and adds essential minerals to achieve a water quality similar to that of mineral water. By adding mineral-rich filter media, it reintegrates essential minerals such as calcium, magnesium, iron, and zinc into the water. These minerals exist in ionic form, making them easier for the body to absorb.

[0003] However, when a reverse osmosis water purifier is working normally, water molecules pass through the membrane to the pure water side under applied pressure, while salt ions remain on the concentrated water side. Therefore, 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 can permeate through the membrane through forward osmosis, causing the TDS value to exceed the normal range. Therefore, whenever a reverse osmosis water purifier is stopped for a period of time and then restarted, the TDS value of the first cup of water will be relatively high. Summary of the Invention

[0004] Based on this, this application proposes a mineralized water system and a mineralized water purifier, which can achieve a two-stage buffering effect and provide sufficient mixed water during backflow rinsing, so that the filter membrane of the reverse osmosis filter unit is rinsed more thoroughly, thereby reducing the TDS value and solving the problem of high TDS value in short-frequency water intake.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the embodiments of this application.

[0032] Figure 1 This is a schematic diagram of a mineralized water system according to an embodiment of this application.

[0033] The mineralized water system 1 may include: an inlet pipe 10, a pre-filter unit 201, a reverse osmosis filter unit 202, a mineralized filter unit 203, and a water pump 204.

[0034] One side of the inlet pipe 10 is the raw water inlet side, used to receive raw water. The other side of the inlet pipe 10 is connected to the inlet side of the pre-filter unit 201, used to flow raw water into the pre-filter unit 201 for water purification. A water pump 204 is located between the pre-filter unit 201 and the reverse osmosis filter unit 202. Specifically, the inlet side of the water pump 204 is connected to the outlet side of the pre-filter unit 201, and the outlet side of the water pump 204 is connected to the inlet side of the reverse osmosis filter unit 202. The inlet side of the mineralization filter unit 203 is connected to the pure water side of the reverse osmosis filter unit 202.

[0035] 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 mineralization filter unit 203 constitute a mineralized water circuit 30. That is, the mineralized water circuit 30 is connected to the inlet side of the reverse osmosis filter unit 202 through the pre-filter unit 201, to the pure water side of the reverse osmosis filter unit 202 through the mineralization filter unit 203, and to the inlet side of the pre-filter unit 201 through the mineralization filter unit 203. Correspondingly, the mineralized water recirculation process is as follows: after the raw water passes through the inlet pipe 10, it first undergoes preliminary filtration through the pre-filter unit 201, then enters the inlet side of the reverse osmosis filter unit 202 under the action of the water pump 204, undergoes purified water filtration through the reverse osmosis filter unit 202, then undergoes mineralization filtration through the mineralization filter unit 203, and finally the mineralized water obtained after mineralization is recirculated back to the pre-filter unit 201.

[0036] In one embodiment, the outlet side of the pre-filter unit 201, the water pump 204, and the concentrate side of the reverse osmosis filter unit 202 constitute a mineralized water circuit 30. That is, the wastewater circuit 40 is connected to the inlet side of the reverse osmosis filter unit 203 via the water pump 204, which is positioned between the inlet sides of the pre-filter unit 201 and the reverse osmosis filter unit 202. Correspondingly, the wastewater recirculation process is as follows: after the raw water passes through the inlet pipe 10, it first undergoes preliminary filtration through the pre-filter unit 201. Then, under the action of the water pump 204, it enters the inlet side of the reverse osmosis filter unit 202, flows back through the concentrate side of the reverse osmosis filter unit 202 to the area between the water pump 204 and the pre-filter unit 201, and finally, the water pump 204 pumps the wastewater recirculated from the wastewater circuit 40 into the inlet side of the reverse osmosis filter unit 202 for rinsing and soaking. Through two stages of reverse osmosis filtration, water conservation can be achieved.

[0037] 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 an open state, and the mineralized water flowing out of the mineralized filter unit 203 is directly discharged through the outlet pipe to provide mineralized water for drinking by the user. After a certain volume / time of water production, the water intake is stopped and the mineralized water control valve 50 is opened, putting the mineralized water circuit 30 in a connected state. This initiates the mineralized water recirculation mode, allowing the mineralized water flowing out of the mineralized filter unit 203 to flow back to the inlet side of the pre-filter unit 201. The mineralized water mixes with the raw water flowing out of the inlet pipe 10 in a certain proportion, and this mixed water flows into the reverse osmosis filter unit 202 to flush the reverse osmosis membrane. This allows the reverse osmosis membrane to be flushed and soaked with water of lower TDS, resulting in a lower concentration of the first cup water in the next intake. This provides a better TDS buffering capacity for the next water intake, thus solving the problem of high TDS values ​​in the first cup water and reducing the TDS value of short-frequency water intake. Furthermore, the water pump 204 can provide sufficient pressure to the reverse osmosis filter unit 202, ensuring a more thorough flushing of the filter membrane.

[0038] Please see Figure 2 As shown, the wastewater circuit 40 includes a first wastewater branch 41 and a second wastewater branch 42. One side of the first wastewater branch 41 is connected to both the inlet side of the second wastewater branch 42 and the concentrate side of the reverse osmosis filter unit 202, while the other side is connected to the outlet side of the pre-filter unit 201. Through the first wastewater branch 41, wastewater generated on the concentrate side of the reverse osmosis filter unit 202 can be returned to the area between the pre-filter unit 201 and the water pump 204. The inlet side of the second wastewater branch 42 is connected to both the inlet side of the first wastewater branch 41 and the concentrate side of the reverse osmosis filter unit 202, and the outlet side of the second wastewater branch 42 serves as a wastewater discharge outlet. Through the first wastewater branch 42, wastewater generated on the concentrate side of the reverse osmosis filter unit 202 can be discharged.

[0039] See also Figure 3 As shown, a wastewater control valve assembly 60 is provided in the wastewater circuit 40. The wastewater control valve assembly 60 includes a wastewater check valve 601, a first wastewater switch valve 602, and a second wastewater switch valve 603.

[0040] The outlet side of the wastewater check valve 601 is located between the pre-filter unit 201 and the water pump 204, and is connected to the inlet side of the water pump 204. The inlet side of the wastewater check valve 601 is connected to the outlet side of the first wastewater switch valve 602. During wastewater recirculation, the wastewater flowing out from the concentrate side of the reverse osmosis filter unit 202 flows through the first wastewater switch valve 602 into the wastewater check valve 601. The wastewater flows from the outlet side of the wastewater check valve 601 into the inlet side of the water pump 204, and then mixes with the water recirculated through the mineralized water circuit to rinse or soak the membrane of the reverse osmosis filter unit 202, so that the next water intake has a better TDS buffering capacity. The inlet side of the second wastewater switch valve 603 is connected to the inlet side of the first wastewater switch valve 602 in the first wastewater branch 41 and the concentrate side of the reverse osmosis filter unit 202, respectively, so as to discharge the wastewater from the concentrate side of the reverse osmosis filter unit 202 and discharge the excess wastewater from the first wastewater switch valve 602.

[0041] In this embodiment, the pure water flowing out of the pure water side of the reverse osmosis filter unit 202 is returned to the pre-filter unit 201 through the mineralization filter unit 203 via the mineralization water circuit. It is mixed with tap water in a certain proportion and then enters the rinsing filter membrane of the reverse osmosis filter unit 202 for a period of time. During this time, the reverse osmosis membrane is rinsed and soaked by water with lower TDS, so the concentration of the first cup water in the next batch will be relatively low. Furthermore, due to the low influent concentration of the membrane, the water concentration in the mineralization filter unit is even lower, resulting in better TDS buffering capacity for the next water intake. Then, the wastewater control valve group 60 is opened in high flow rate mode, the mineralization water circuit is closed, and the tap water is pushed out of the mixed water in the pre-filter unit to replace the raw water and concentrate in the reverse osmosis filter unit, so that the reverse osmosis membrane is in a water quality environment with lower TDS, thereby further reducing the TDS of the first cup water in the next batch and effectively solving the problem of high TDS value in the next first cup water.

[0042] Please see Figure 4 As shown, the mineralization filter unit 203 includes: a mineralization pipeline 121, an inhibition pipeline 122, and a promotion pipeline 123. A mineralization filter element 124 is installed on the mineralization pipeline 121, an inhibition filter element 125 is installed on the inhibition pipeline 122, and a promotion filter element 126 is installed on the promotion pipeline 123.

[0043] In an optional embodiment, the mineralization pipeline 121, the inhibition pipeline 122, and the promotion pipeline 123 are arranged in parallel and can discharge water simultaneously. Specifically, the mineralization pipeline 121, the inhibition pipeline 122, and the promotion pipeline 123 are connected in parallel between the inlet pipeline 109 and the outlet pipeline 60 of the mineralization filter unit 203. The inlet pipeline 109 can be connected to the mineralization pipeline 121, the inhibition pipeline 122, and the promotion pipeline 123 via a multi-way valve or a diverter valve, and the mineralization pipeline 121, the inhibition pipeline 122, and the promotion pipeline 123 can be connected to the outlet pipeline 60 via a multi-way valve. When the mineralization pipeline 121, the inhibition pipeline 122, and the promotion pipeline 123 discharge water simultaneously, the water discharged from the mineralization pipeline 121, the inhibition pipeline 122, and the promotion pipeline 123 can be mixed and discharged through the outlet pipeline 60.

[0044] By installing the mineralizing filter element 124 in the mineralizing pipeline 121, the mineralizing filter element 124 can release (dissolve) minerals into the flowing water, thereby ensuring that the water output from the mineralizing pipeline 121 contains minerals to meet people's requirements for mineralized drinking water. By installing the inhibition filter element 125 in the inhibition pipeline 122, the inhibition filter element 125 can release inhibition substances into the flowing water. When water containing inhibition substances flows through the mineralizing filter element 124, it can inhibit the dissolution of minerals in the mineralizing filter element 124, thereby preventing excessively high mineral content in the water. By installing the promotion filter element 126 in the promotion pipeline 123, the promotion filter element 126 can release promotion substances into the flowing water. When water containing promotion substances flows through the mineralizing filter element 124, it can promote the dissolution of minerals in the mineralizing filter element 124, thereby increasing the mineral content in the water.

[0045] In an optional embodiment, the mineralization filter unit 203 further includes a first connecting pipe 127. The first connecting pipe 127 is disposed between the mineralization pipe 121 and the suppression pipe 122, for connecting the suppression filter 125 and the mineralization filter 124 in series. The output side of the first connecting pipe 127 is connected to the mineralization pipe 121 or the mineralization filter 124, and the input side of the first connecting pipe 127 is connected to the suppression pipe 122 or the suppression filter 125. Thus, a mineralization treatment structure is formed with the suppression filter 125 upstream and the mineralization filter 124 downstream, allowing water containing the suppression substance to flow through the water path of the mineralization filter 124.

[0046] In an optional embodiment, the mineralization filter unit 203 further includes a second connecting pipe 128. The second connecting pipe 128 is disposed between the mineralization pipe 121 and the promoting pipe 123, for connecting the promoting filter 126 and the mineralization filter 124 in series. The output side of the first connecting pipe 127 is connected to the mineralization pipe 121 or the mineralization filter 124, and the input side of the first connecting pipe 127 is connected to the promoting pipe 123 or the promoting filter 126. Thus, a mineralization treatment structure is formed with the promoting filter 126 upstream and the mineralization filter 124 downstream, allowing water containing promoting substances to flow through the water path of the mineralization filter 124.

[0047] In an optional embodiment, a first control valve 1291 is provided on the first connecting pipe 127. The first control valve 1291 has a water flow-through state and a water flow-independent state. In specific applications, the first control valve 1291 can also be a flow valve.

[0048] In an optional embodiment, a second control valve 1292 is provided on the second connecting pipe 128. The second control valve 1292 has a water flow-through state and a water flow-independent state. In specific applications, the second control valve 1292 can also be a flow valve.

[0049] In an optional embodiment, a third control valve 1293 for controlling the on / off state and / or flow rate of the mineralization pipeline 121 is provided on the mineralization pipeline 121. The third control valve 1293 is located on the upstream side of the mineralization filter element 124.

[0050] In an optional embodiment, a fourth control valve 1294 is provided on the suppression pipeline 122 for controlling the on / off state and / or flow rate of the suppression pipeline 122. The fourth control valve 1294 is located downstream of the suppression filter element 125, and by controlling the opening or closing of the fourth control valve 1294, water can be supplied to the suppression filter element 125.

[0051] In an optional embodiment, a fifth control valve 1295 is provided on the promoting pipeline 123 for controlling the on / off state and / or flow rate of the promoting pipeline 123. The fifth control valve 1295 is located downstream of the promoting filter element 126, and by controlling the opening or closing of the fifth control valve 1295, water can be supplied to the promoting filter element 126.

[0052] One side of the first connecting pipe 127 is connected between the third control valve 1293 and the mineralizing filter element 124, and the other side is connected between the suppression filter element 125 and the fourth control valve 1294. Since the third control valve 1293 is located upstream of the mineralizing filter element 124 and the fourth control valve 1294 is located downstream of the suppression filter element 125, the input side of the first connecting pipe 127 is connected to the downstream side of the suppression filter element 125, and the output side of the first connecting pipe 127 is connected to the upstream side of the mineralizing filter element 124. When the third control valve 1293 and the fourth control valve 1294 are closed, and the first control valve 1291 is in a water flow-through state, water containing the inhibitory substance can flow to the first connecting pipe 127, and then to the mineralizing filter element 124.

[0053] One side of the second connecting pipe 128 is connected between the third control valve 1293 and the mineralizing filter element 124, and the other side is connected between the promoting filter element 126 and the fifth control valve 1295. Since the third control valve 1293 is located upstream of the mineralizing filter element 124 and the fifth control valve 1295 is located downstream of the promoting filter element 126, the input side of the second connecting pipe 128 is connected to the downstream side of the promoting filter element 126, and the output side of the second connecting pipe 128 is connected to the upstream side of the mineralizing filter element 124. When the third control valve 1293 and the fifth control valve 1295 are closed, and the second control valve 1292 is in a water flow-through state, water containing the promoting substance can flow to the second connecting pipe 128, and then to the mineralizing filter element 124.

[0054] 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, water can be discharged simultaneously or individually from at least any two of the mineralization pipeline 121, the suppression pipeline 122, and the promotion pipeline 123. Furthermore, water flowing through the suppression filter element 125 can enter the mineralization filter element 124 through the first connecting pipeline 127, or water flowing through the promotion filter element 126 can enter the mineralization filter element 124 through the second connecting pipeline 128, etc., thereby enabling the pipeline structure to meet different requirements.

[0055] For example, when the mineralization pipeline 121, the inhibition pipeline 122, and the promotion pipeline 123 need to discharge water simultaneously, the third control valve 1293, the fourth control valve 1294, and the fifth control valve 1295 can be opened, and the first control valve 1291 and the second control valve 1292 can be controlled to be in a state where water flow cannot pass through. At this time, the first connecting pipeline 127 and the second connecting pipeline 128 are disconnected. The mineralization pipeline 121, the inhibition pipeline 122, and the promotion pipeline 123 are connected between the inlet pipeline 109 and the outlet pipeline 60 and are arranged in parallel. The water in the mineralization pipeline 121, the inhibition pipeline 122, and the promotion pipeline 123 are mixed in the outlet pipeline 60 and then discharged.

[0056] For example, when the mineralizing filter element 124 is in the soaking state, the first control valve 1291 can be controlled to be in the water flow-through state, the second control valve 1292 can be controlled to be in the water flow-blocking state, 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 pipe 128 and the promoting pipe 123 are both disconnected, and the inhibiting filter element 125 and the mineralizing filter element 124 are connected through the first connecting pipe 127. Water containing the inhibiting substance can flow to the mineralizing filter element 124 through the first connecting pipe 127, thereby allowing the water containing the inhibiting substance to enter and fill the mineralizing filter element 124, and the mineralizing filter element 124 can be soaked by the water containing the inhibiting substance.

[0057] For example, to prevent the mineralization filter element 124 from exceeding the mineral content standard due to soaking and to add new mineral types to the water, the first control valve 1291 can be controlled to be in a water flow-through state, the second control valve 1292 can be controlled to be in a water flow-blocking state, 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 pipe 128 is disconnected; the inhibition filter element 125 and the mineralization filter element 124 are connected through the first connecting pipe 127, and the water containing the inhibition substance can flow to the mineralization filter element 124 through the first connecting pipe 127, thereby inhibiting the release of minerals by the mineralization filter element 124 to prevent the mineral content in the water from exceeding the standard content; the promoting pipe 123 is connected, and the water containing the promoting substance can flow to the outlet pipe 60, wherein the promoting filter element 126 may include filter material that releases minerals, thereby enabling the addition of new mineral types to the water. For example, the 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 the water, improve the taste of drinking water, and maintain human health.

[0058] For example, when the mineralizing filter element 124 is in the middle to late stage of its service life, the first control valve 1291 can be controlled to be in a state where water flow is prohibited, the second control valve 1292 can be controlled to be in a state where water flow is permitted, 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 pipe 127 and the suppression pipe 122 are both disconnected, and the promoting filter element 126 and the mineralizing filter element 124 are connected through the second connecting pipe 128. Water containing promoting substances can flow to the mineralizing filter element 124 through the second connecting pipe 128, thereby promoting the release of minerals by the mineralizing filter element 124 so that the mineral content in the water meets the standards. Even if the mineralizing filter element 124 is in the middle to late stage of its service life (the mineral dissolution rate decreases), by setting the promoting filter element 126, the mineral dissolution rate in the mineralizing filter element 124 can be kept within a set range, and the service life of the mineralizing filter element 124 can be extended. Alternatively, when a large flow rate is expected, the first control valve 1291 can be controlled to be in a state where water flow is not allowed, the second control valve 1292 can be controlled to be in a state where water flow is allowed, 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 can meet the standards when the flow rate is large.

[0059] For example, when a large flow rate is anticipated and new mineral types are added to the water body, the first control valve 1291 can be controlled to be in a state where water flow is prohibited, the second control valve 1292 can be controlled to be in a state where water flow is permitted, 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 pipe 127 is disconnected; the promoting filter element 126 and the mineralizing filter element 124 are connected through the second connecting pipe 128, and the water containing the promoting substance can flow to the mineralizing filter element 124 through the second connecting pipe 128, thereby promoting the release of minerals by the mineralizing filter element 124 so that the minerals in the water body can meet the standards; the inhibiting pipe 122 is connected, and the water containing the inhibiting substance can flow to the outlet pipe 60, wherein the inhibiting filter element 125 may include filter media that releases minerals, thereby enabling the addition of new mineral types to the water body. For example, the filter cartridge 125 includes the zeolite filter material described below. The zeolite filter material releases (dissolves) minerals such as zeolite, which can adsorb harmful substances such as heavy metals, ammonium and hydrogen compounds in the water, greatly improving water quality. In addition, zeolite can also adjust the pH value of the water, improve the taste of drinking water, and maintain human health.

[0060] In one 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.

[0061] In one optional embodiment, the mineralizing filter element 124 includes a filter material containing metasilicic acid, the inhibiting filter element 125 includes a zeolite filter material, and the promoting filter element 126 includes an alkaline filter material. In other embodiments, the mineralizing 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 mineralizing 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 inhibiting filter element 125 should be matched with a corresponding inhibiting filter material.

[0062] In an optional embodiment, the mineralizing filter element 124 comprises maifanite, the promoting filter element 126 comprises periclase, and the inhibiting filter element 125 comprises zeolite.

[0063] By employing the aforementioned filter element unit 50, water containing inhibitory substances is supplied to the mineralization filter element 124 to inhibit the release of minerals by the mineralization filter element 124, thereby preventing the occurrence of excessively high mineral content in the water; and water containing promoting substances is supplied to the mineralization filter element 124 to promote the release of minerals by the mineralization filter element 124, thereby preventing the occurrence of substandard mineral content in the water.

[0064] Please see Figure 5 As shown, the mineralization filter element unit 203 includes: a mineralization pipeline 101 and an inhibition pipeline 102. A mineralization filter element 103 is provided on the mineralization pipeline 101, and an inhibition filter element 104 is provided on the inhibition pipeline 102.

[0065] In an optional embodiment, the mineralization pipeline 101 and the suppression pipeline 102 are connected in parallel and can discharge water simultaneously. Specifically, the mineralization pipeline 101 and the suppression pipeline 102 are connected in parallel between the inlet pipeline 109 and the outlet pipeline 60 of the mineralization filter unit 203. The inlet pipeline 109 can be connected to the mineralization pipeline 101 and the suppression pipeline 102 via a three-way valve or a diverter valve, and the mineralization pipeline 101 and the suppression pipeline 102 can be connected to the outlet pipeline 60 via a three-way valve. When the mineralization pipeline 101 and the suppression pipeline 102 discharge water simultaneously, the water from the mineralization pipeline 101 and the suppression pipeline 102 can be mixed and discharged through the outlet pipeline 60.

[0066] By installing the mineralizing filter element 103 in the mineralizing pipeline 101, the mineralizing filter element 103 can release (dissolve) minerals into the flowing water, thereby ensuring that the water output from the mineralizing pipeline 101 contains minerals to meet people's requirements for mineralized drinking water. By installing the inhibition filter element 104 in the inhibition pipeline 102, the inhibition filter element 104 can release inhibition substances into the flowing water. When water containing inhibition substances flows through the mineralizing filter element 103, it can inhibit the dissolution of minerals in the mineralizing filter element 103, thereby preventing excessively high mineral content in the water.

[0067] In an optional embodiment, the mineralization filter unit 203 further includes a series switching conduit 105. The series switching conduit 105 is disposed between the mineralization conduit 101 and the suppression conduit 102, for connecting the suppression filter 104 and the mineralization filter 103 in series. The output side of the series switching conduit 105 is connected to the mineralization conduit 101 or the mineralization filter 103, and the input side of the series switching conduit 105 is connected to the suppression conduit 102 or the suppression filter 104.

[0068] 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 suppression substance flows through the water path of the mineralization filter element 103.

[0069] In specific implementation, to prevent excessive mineral content in the water, water containing inhibitory substances can be allowed to flow through the mineralization filter element 103 via a series switching pipe 105. This inhibits the release of minerals from the mineralization filter element 103, thereby reducing the mineral content in the water. When the mineralization filter element 103 is in a soaking state, for example, if the water flow rate in the mineralization pipe 101 is too slow, stops flowing, or stops flowing for a set period, it may lead to excessively high mineral content in the water (especially in the mineralization filter element 103). By using the series switching pipe 105 to allow water containing inhibitory substances to enter the mineralization filter element 103, the release of minerals from the soaking mineralization filter element 103 is inhibited, thus preventing excessively high mineral content in the water. In this embodiment, the soaking state refers to a situation where the flow rate in the filter element is less than the design threshold, including situations where the water stops flowing or the flow rate is slow.

[0070] In an optional embodiment, a first control valve 106 is provided on the series switching pipeline 105.

[0071] The first control valve 106 has a water flow passable state and a water flow impassable state. In specific applications, the first control valve 106 can also be a flow valve. By setting the first control valve 106 on the series switching pipeline 105, it is possible to control whether the water flow can pass through the series switching pipeline 105 from the suppression filter element 104 to the mineralization filter element 103. For example, when the mineralizing filter element 103 is in a soaking state, the first control valve 106 can be set to a water flow-through state. Therefore, water can flow from the suppression filter element 104 to the mineralizing filter element 103 through the series switching pipeline 105, thereby suppressing the release of minerals by the mineralizing filter element 103, reducing the mineral content in the water, preventing the mineral content from exceeding the set standard, and thus controlling the mineral content within a safe standard range. When the water flow rate of the mineralizing pipeline 101 exceeds the set flow rate, the concentration of minerals in the water flowing through the mineralizing filter element 103 will not exceed the set standard. When it is not necessary to reduce the mineral content in the water, the first control valve 106 can be set to a water flow-through-no-passage state.

[0072] In an optional embodiment, the mineralization filter element unit 203 further includes a second control valve 107, which is disposed in the mineralization pipeline 101 and located upstream of the mineralization filter element 103.

[0073] The second control valve 107 is used to control the on / off state and / or flow rate of the mineralization pipeline 101. By controlling the opening or closing of the second control valve 107, water can be supplied to the mineralization filter element 103. By controlling the flow rate of the mineralization pipeline 101 through the second control valve 107, the amount of minerals released by the mineralization filter element 103 into 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 a unit volume of water will decrease; when the water flow rate of the mineralization pipeline 101 is lower than the set flow rate, the mineral content in a unit volume of water will increase. Therefore, the flow rate of the mineralization pipeline 101 can be adjusted through the second control valve 107, thereby adjusting the mineral content in the water of the mineralization pipeline 101.

[0074] The output side of the series switching pipeline 105 is connected between the second control valve 107 and the mineralization filter element 103. With this configuration, the output side of the series switching pipeline 105 is connected to the upstream side of the mineralization filter element 103, which enables the water in the series switching pipeline 105 to flow to the mineralization filter element 103.

[0075] In an optional embodiment, the mineralization filter element unit 203 further includes a third control valve 108, which is disposed in the suppression pipeline 102 and located downstream of the suppression filter element 104.

[0076] The third control valve 108 is used to control the on / off state 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 configuration, 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 open, water containing the suppression substance can flow to the series switching pipeline 105, thereby causing the water containing the suppression substance to flow to the mineralization filter element 103.

[0077] By controlling the opening or closing of the second control valve 107 and the third control valve 108, and controlling whether the water flow through the first control valve 106 is allowed, water can be discharged simultaneously or separately from the mineralization pipeline 101 and the suppression pipeline 102, and the water flowing through the suppression filter element 104 can enter the mineralization filter element 113 through the series switching pipeline 115.

[0078] For example, when both the mineralization pipeline 101 and the suppression pipeline 102 need to discharge water simultaneously, the second control valve 107 and the third control valve 108 can be opened, while the first control valve 106 is closed. At this time, the series switching pipeline 105 is disconnected, and the mineralization pipeline 101 and the suppression pipeline 102 are connected in parallel. The water containing minerals in the mineralization pipeline 101 and the water containing inhibitory substances in the suppression pipeline 102 can be mixed in the outlet pipeline 60 before being discharged.

[0079] For example, when mineralization pipeline 101 needs to discharge water separately, the second control valve 107 can be opened, and the first control valve 106 and the third control valve 108 can be closed. At this time, mineralization pipeline 101 is open, and suppression pipeline 102 and series switching pipeline 105 are disconnected. The mineral-containing water in mineralization pipeline 101 can be discharged through water outlet pipeline 60.

[0080] For example, when the mineralizing filter element 103 is in the soaking state, the second control valve 107 and the third control valve 108 can be closed and the first control valve 106 can be opened. At this time, the inhibition filter element 104 and the mineralizing filter element 103 are connected through the series switching pipeline 105, and the water containing the inhibition substance can flow to the mineralizing filter element 103 through the series switching pipeline 105.

[0081] In one 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.

[0082] In an optional embodiment, the mineralizing filter element 103 includes zinc-containing filter media (e.g., smithsonite, zincblende), and the inhibition filter element 104 includes alkaline filter media (e.g., magnesite, brucite, sepiolite, calcite). Zinc is indispensable for cell replication, immune activity, tissue repair, and growth, and is a key element in growth and development, reproductive heredity, the immune system, and bone metabolism. Therefore, by configuring the mineralizing filter element 103 to include zinc-containing filter media, the release of mineral zinc into the water is beneficial to human health. Furthermore, water with a pH between 7.0 and 9.0 is considered optimal for human health; by configuring the inhibition filter element 104 to include alkaline filter media, it is beneficial to maintain the water quality within the pH range of 7.0 to 9.0.

[0083] It should be noted that while zinc is an essential trace element for the human body, contributing to growth and development and participating in vitamin metabolism, excessive zinc in drinking water can lead to excessive zinc intake, causing harm such as zinc poisoning and abnormal lipid metabolism. Therefore, by incorporating the inhibitor filter 104 to suppress excessive zinc release, high zinc concentrations can be avoided.

[0084] It is understood that in other embodiments, the mineralizing filter element 103 may also include filter media containing other minerals, such as copper, calcium, magnesium, potassium, strontium, etc. It should be noted that when the mineralizing filter element 103 includes filter media containing other minerals, the corresponding suppressing filter media can be matched in the suppressing filter element 104.

[0085] In an optional embodiment, the mineralizing filter element 103 includes a first alkaline filter material, and the inhibiting filter element 104 includes a second alkaline filter material. The alkalinity of the first alkaline filter material is weaker than that of the second alkaline filter material, and the alkalinity of the second alkaline filter material is stronger than that of the first alkaline filter material. Therefore, the second alkaline filter material can be used to inhibit the leaching of alkaline substances in the first alkaline filter material. For example, the first alkaline filter material (weakly alkaline) is filled with maifanite or tourmaline, and the second alkaline filter material (strongly alkaline) is filled with a high concentration of zinc and magnesium.

[0086] By filling the first alkaline filter media with weakly alkaline minerals and the second alkaline filter media with strongly alkaline minerals, when water flows through the first alkaline filter media, the alkaline substances precipitated from the first alkaline filter media raise the pH value of the water. Subsequently, when the water flows into the inhibition filter element 104, since the pH value of the water has already been raised by the first alkaline filter media, the precipitation of minerals such as zinc and copper in the second alkaline filter media is inhibited to a certain extent (usually because the solubility of these minerals decreases or the precipitation rate slows down at higher pH values).

[0087] By using the above-mentioned filter element unit 50, when the mineral content in the water is too high, the release or dissolution of minerals in the mineralization filter element can be inhibited, thereby reducing the mineral content in the water.

[0088] Please see Figure 6 As shown, the mineralization filter element unit 203 includes: a mineralization pipeline 111 and a promotion pipeline 112. A mineralization filter element 113 is provided on the mineralization pipeline 111, and a promotion filter element 114 is provided on the promotion pipeline 112.

[0089] In an optional embodiment, the mineralization pipeline 111 and the promoting pipeline 112 are connected in parallel and can discharge water simultaneously. Specifically, the mineralization pipeline 111 and the promoting pipeline 112 are connected in parallel between the inlet pipeline 109 and the outlet pipeline 60 of the mineralization filter unit 203. The inlet pipeline 109 can be connected to the mineralization pipeline 111 and the promoting pipeline 112 via a three-way valve or a diverter valve, and the mineralization pipeline 111 and the promoting pipeline 112 can be connected to the outlet pipeline 60 via a three-way valve. When the mineralization pipeline 111 and the promoting pipeline 112 discharge water simultaneously, the water from the mineralization pipeline 111 and the promoting pipeline 112 can be mixed and discharged through the outlet pipeline 60.

[0090] By installing the mineralizing filter element 113 in the mineralizing pipeline 111, the mineralizing filter element 113 can release (dissolve) minerals into the flowing water, thereby ensuring that the water output from the mineralizing pipeline 111 contains minerals to meet people's requirements for mineralized drinking water. By installing the promoting filter element 114 in the promoting pipeline 112, the promoting filter element 114 can release promoting substances into the flowing water. When water containing promoting substances flows through the mineralizing filter element 113, it can promote the dissolution of minerals in the mineralizing filter element 113, thereby increasing the mineral content in the water.

[0091] In an optional embodiment, the mineralization filter unit 203 further includes a series switching conduit 115. The series switching conduit 115 is disposed between the mineralization conduit 111 and the promoting conduit 112, for connecting the promoting filter element 114 and the mineralization filter element 113 in series. The output side of the series switching conduit 115 is connected to the mineralization conduit 111 or the mineralization filter element 113, and the input side of the series switching conduit 115 is connected to the promoting conduit 112 or the promoting filter element 114.

[0092] 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 promoting pipeline 112 or the promoting filter element 114, a mineralization treatment structure can be formed in which the promoting filter element 114 is located upstream and the mineralization filter element 113 is located downstream, and water containing promoting substances flows through the water path of the mineralization filter element 113.

[0093] Water containing a promoting agent flows into the mineralization filter element 113, enabling the agent to promote the release of minerals by the filter element 113, increasing the mineral content in the water and preventing the mineral content from falling below the standard. For example, when the water flow rate in the mineralization pipe 111 exceeds the set flow rate (i.e., the water flow rate is at a high flow rate), the water flow velocity increases, and the amount of minerals released per unit volume of water decreases. By connecting the series switching pipe 115 to allow water containing the promoting agent to flow into the mineralization filter element 113, the release of minerals by the filter element 113 is promoted, increasing the mineral content in the water. When the mineralization filter element 113 has been used for a certain period of time and reaches the middle to late stage of its service life, the performance of the mineral release function of the filter element 113 decreases. By promoting the release of minerals by the filter element 113 with the promoting agent, the mineral content in the water can be effectively increased, thereby ensuring that the mineral content in the water meets the standard and extending the service life of the mineralization filter element 113.

[0094] In an optional embodiment, a first control valve 116 is provided on the series switching pipeline 115.

[0095] The first control valve 116 has a water flow passable state and a water flow impassable state. In specific applications, the first control valve 116 can also be a flow valve. By setting the first control valve 116 on the series switching pipeline 115, it is possible to control whether the water flow can pass through the series switching pipeline 115 from the facilitator filter element 114 to the mineralization filter element 113. When the water flow rate in the mineralization pipeline 111 is high, or when the mineralization filter element 113 has reached the middle or late stage of its service life, the first control valve 116 can be set to a water flow-through state. At this time, the water can flow from the promoting 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, increasing the mineral content in the water, preventing the mineral content from falling below the set standard, and thus controlling the mineral content within a safe standard range. When the water flow rate in the mineralization pipeline 111 is lower than the set flow rate, or when the mineralization filter element 113 is in the early stage of its service life, the concentration of minerals in the water flowing through the mineralization filter element 113 will not be lower than the set standard, and the mineral content in the water meets the standard. At this time, the first control valve 116 can be set to a water flow-through-no-passage state.

[0096] In an optional embodiment, the mineralization filter element unit 203 further includes a second control valve 117, which is disposed in the mineralization pipeline 111 and located upstream of the mineralization filter element 113.

[0097] The second control valve 117 is used to control the on / off state and / or flow rate of the mineralization pipeline 111. By controlling the opening or closing of the second control valve 117, water can be supplied to the mineralization filter element 113. By controlling the flow rate of the mineralization pipeline 111 through the second control valve 117, the amount of minerals released by the mineralization filter element 113 into 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 a unit volume of water will decrease; when the water flow rate of the mineralization pipeline 111 is lower than the set flow rate, the mineral content in a 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 mineral content in the water of the mineralization pipeline 111.

[0098] The output side of the series switching pipeline 115 is connected between the second control valve 117 and the mineralization filter element 113. With this configuration, the output side of the series switching pipeline 115 is connected to the upstream side of the mineralization filter element 113, which enables the water in the series switching pipeline 115 to flow to the mineralization filter element 113.

[0099] In an optional embodiment, the mineralization filter element unit 203 further includes a third control valve 118, which is disposed in the promoting pipeline 112 and located downstream of the promoting filter element 114.

[0100] The third control valve 118 is used to control the on / off state and / or flow rate of the promoting pipeline 112. The input side of the series switching pipeline 115 is connected between the promoting filter element 114 and the third control valve 118. In this configuration, the input side of the series switching pipeline 115 is connected to the downstream side of the promoting filter element 114. When the third control valve 118 is closed and the first control valve 116 is open, water containing the promoting substance can flow to the series switching pipeline 115, thereby causing the water containing the promoting substance to flow to the mineralization filter element 113.

[0101] By controlling the opening or closing of the second control valve 117 and the third control valve 118, and controlling whether the water flow can pass through the first control valve 116, water can be discharged simultaneously or separately from the mineralization pipeline 111 and the promotion pipeline 112, and the water flowing through the promotion filter element 114 can enter the mineralization filter element 113 through the series switching pipeline 115.

[0102] For example, when mineralization pipeline 111 and promoting pipeline 112 need to discharge water simultaneously, the second control valve 117 and the third control valve 118 can be opened, and the first control valve 116 can be closed. At this time, the series switching pipeline 115 is disconnected, and mineralization pipeline 111 and promoting pipeline 112 are connected in parallel. The water containing minerals in mineralization pipeline 111 and the water containing promoting substances in promoting pipeline 112 can be mixed in the outlet pipeline 60 and then discharged.

[0103] For example, when mineralization pipeline 111 needs to discharge water separately, the second control valve 117 can be opened and the first control valve 116 and the third control valve 118 can be closed. At this time, mineralization pipeline 111 is connected, which promotes the disconnection of pipeline 112 and series switching pipeline 115. The mineral-containing water in mineralization pipeline 111 can be discharged through water outlet pipeline 60.

[0104] For example, when the mineralizing filter element 113 is in the middle to late stage of its service life, the first control valve 116 can be opened, while the second control valve 117 and the third control valve 118 can be closed. At this time, the promoting filter element 114 and the mineralizing filter element 113 are connected through the series switching pipe 115. Water containing promoting substances can flow to the mineralizing filter element 113 through the series switching pipe 115, thereby promoting the release of minerals from the mineralizing filter element 113 so that the mineral content in the water meets the standards. Even if the mineralizing filter element 113 is in the middle to late stage of its service life (the mineral dissolution rate decreases), by setting the promoting filter element 114, the mineral dissolution rate in the mineralizing filter element 113 can be kept within a set range, thus extending the service life of the mineralizing filter element 113. Alternatively, when the flow rate is high, the first control valve 116 can also be opened, while the second control valve 117 and the third control valve 118 can be closed, ensuring that the mineral content in the water meets the standards even at high flow rates.

[0105] In one 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.

[0106] In an optional embodiment, the mineralizing 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 its levels tend to decrease significantly with age. Modern medicine shows that silicon affects the synthesis of bone tissue biomolecules, is related to bone growth and structure, plays a physiological role in bone calcification, and can promote bone development. Insufficient intake will reduce the calcium content of bones. A lack of silicon in the body can also lead to growth retardation, skeletal abnormalities, deformities (especially of the skull), and dysplasia of teeth or tooth enamel. Silicon can also enhance the strength of elastic fibers in blood vessels, especially the intima elastic layer, thus forming a barrier that effectively prevents lipid invasion. This property gives silicon an anti-atherosclerotic effect, maintaining the integrity of elastic fibers and interstitial tissue, thereby preventing the formation of atherosclerotic plaques. Silicon can also remove fat deposits on the inner walls of blood vessels; this mechanism can alleviate arteriosclerosis, cardiovascular, and heart diseases.

[0107] The silicon needed by the human body generally comes from water, and the silicon in water exists in the form of metasilicic acid, which is easily absorbed by the human body and skin. Therefore, by incorporating a mineralization filter element 113 containing metasilicic acid filter material, the mineralization filter element 113 can release metasilicic acid into the water, which is beneficial to human health.

[0108] In addition, water with a pH value between 7.0 and 9.0 is the optimal water quality for human health. By setting the filter cartridge 114 to include alkaline filter media, it is beneficial to keep the water quality within the pH range of 7.0 to 9.0, which is conducive to human health.

[0109] It is understood that in other embodiments, the mineralizing filter element 113 may also include filter media containing other minerals, such as copper, calcium, magnesium, potassium, strontium, zinc, etc. It should be noted that when the mineralizing filter element 113 includes filter media containing other minerals, a corresponding promoting filter media can be matched in the promoting filter element 114.

[0110] In an optional embodiment, the mineralizing filter element 113 comprises maifanite, and the promoting filter element 114 comprises periclase. By using maifanite as the filter material of the mineralizing filter element 113, beneficial metasilicic acid can be released without producing harmful substances.

[0111] By using the above-mentioned filter element unit 50, when the mineral content in the water is insufficient, the release or dissolution of minerals in the mineralization filter element can be promoted to increase the mineral content in the water.

[0112] Please see Figure 7 As shown, the mineralization filter element unit 203 includes: a mineralization pipeline 901, on which a mineralization filter element 9010 is provided.

[0113] Mineralized pipe 901 is the channel through which water flows, ensuring that water can pass through smoothly and efficiently without introducing any contaminants.

[0114] The 9010 mineralizer cartridge adds beneficial minerals to the water flow to improve its taste and nutritional value. The 9010 mineralizer cartridge may be made from a variety of materials, including but not limited to maifan stone, tourmaline, and weakly alkaline mineralizing balls.

[0115] In practical applications, 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 pipe 901 and then flows through the mineralization filter element 9010. The water comes into contact with and exchanges with the materials in the mineralization filter element 9010, thereby absorbing beneficial minerals. After mineralization treatment, the taste and nutritional value of the water are improved, making it more suitable for drinking.

[0116] Please see Figure 8As shown, the mineralized filter element unit 203 includes: a first water quality meter 130 and a second water quality meter 132.

[0117] The first water quality meter 130 can be installed at the inlet of the mineralization filter unit 203. In an optional embodiment, the first water quality meter is installed on the inlet pipe 109 of the mineralization filter unit 203 to detect a first water quality parameter upstream of the mineralization filter unit 50. The second water quality meter 132 can be installed at the outlet of the mineralization filter unit 203. In an optional embodiment, the second water quality meter 132 is installed on the outlet pipe 60 of the mineralization filter unit 203 to detect a second water quality parameter downstream of the mineralization filter unit.

[0118] The water quality analyzers (first water quality analyzer 130 and second water quality analyzer 132) can be either total dissolved solids (TDS) analyzers or conductivity meters. When the first water quality analyzer 130 and second water quality analyzer 132 are used for TDS analysis, the corresponding first water quality parameter is a first TDS value, and the corresponding second water quality parameter is a second TDS value. When the first water quality analyzer 130 and second water quality analyzer 132 are used for conductivity analysis, the corresponding first water quality parameter is a first conductivity value, and the corresponding second water quality parameter is a second conductivity value.

[0119] Total dissolved solids (TDS) refers to the total amount of solids dissolved in water, including both inorganic and organic matter. The unit of measurement is milligrams per liter (mg / L = 1 ppm), indicating how many milligrams of total dissolved solids are dissolved in one liter of water. A higher TDS value indicates a greater amount of dissolved matter in the water. Generally, conductivity can be used to roughly estimate the salinity of a solution; higher conductivity indicates higher salinity and a higher TDS value. Higher conductivity also indicates a higher ion concentration in the water, potentially containing more dissolved substances.

[0120] In one embodiment, the first water quality meter 130 and the second water quality meter 132 are electrically connected to the controller, respectively. The first water quality meter 130 transmits the detected first water quality parameter to the controller, and the second water quality meter 130 transmits the detected second water quality parameter to the controller.

[0121] After obtaining the first and second water quality parameters, the controller can calculate the pH value based on these parameters. Based on the pH value, the controller controls the opening and closing of the mineralized water control valve 50, thereby controlling the on / off state of the mineralized water circuit 30. Specifically, the controller determines whether the pH value is higher than a preset pH threshold. When the controller determines that the pH value is higher than the preset pH threshold, it can control the mineralized water control valve 50 to close, thus disconnecting the mineralized water circuit 30. When the controller determines that the pH value is lower than the preset pH threshold, it can control the mineralized water control valve 50 to open, thus connecting the mineralized water circuit 30.

[0122] In other embodiments, the controller can also control the opening and closing of each control valve in the mineralization filter unit 203 according to the water quality pH value, so as to keep the pH value of the water filtered by the mineralization filter unit 203 within the preset water quality pH threshold range.

[0123] In one embodiment, the controller calculates the difference in water quality parameters based on the second water quality parameter and the first water quality parameter. Based on a preset correspondence between the water quality parameter difference and the pH value, the pH value of the water filtered by the mineralization filter unit 203 can be obtained. This correspondence is a mathematical function obtained by fitting the relationship between the water quality parameter difference and the pH value using data fitting methods (such as linear regression, multinomial regression, machine learning algorithms, etc.).
