Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and particularly to a mineralization device, a water purifier, and a method for adjusting the mineral concentration. Background Art

[0002] In recent years, more and more residents have started to use water purifiers. Most of these water purifiers use reverse osmosis technology, which can remove almost all pollutants and minerals in water. Therefore, reverse osmosis water purifiers are widely installed in public places and households, and most of these reverse osmosis water purifiers do not have a remineralization module. Deep-processed foods and highly purified water make it difficult for people to obtain sufficient minerals to maintain the body's metabolic balance, and the potential impact on human health may last for a long time, which is undoubtedly catastrophic for public health. Especially for the mother and baby group, the health risks and impacts of drinking water will be amplified.

[0003] Due to the need of the mother and baby group for healthy drinking water, a large number of water purifiers with mother and baby concepts have emerged on the market. Most of these mother and baby water purifiers improve the filtration performance and sterilization performance of the water purifier. Through the application of ultraviolet sterilization and high-flux reverse osmosis membranes, the safety of drinking water has been maximized, but the mineral nutrition of drinking water has been ignored. For the mother and baby population, the best solution for healthy drinking water is to purify and then remineralize. However, there are significant differences in the mineral requirements of the applicable population targeted by mother and baby water purifiers. For example, the daily requirements for calcium and magnesium of infants, pregnant women, and lactating women are different, and there are also differences in the mineral requirements of infants, pregnant women, and lactating women of different ages. Therefore, mother and baby water purifiers should not only consider the mineral balance in drinking water, but also supply water of different qualities for infants, pregnant women, and lactating women of different ages.

[0041] Embodiment 1

[0042] Reference Figure 1 , which is an embodiment of the mineralization device of the present invention, includes a mineralization box 100, a high water level tank 200, a low water level tank 300, a first water storage tank 400, a second water storage tank 500 and a mineral detection component 610.

[0043] A porous mineralizing medium 110 is arranged in the inner cavity of the mineralizing box 100. The mineralizing medium can be a substance containing a large amount of trace elements required by the human body, such as wooden fish stone, medical stone, etc.

[0044] The high water level tank 200 is disposed on one side of the mineralized water tank and is separated from the mineralized water tank by a first porous partition. A water inlet pipe 710 is disposed on the high water level tank 200, and a water inlet solenoid valve 711 is disposed on the water inlet pipe 710.

[0045] The low water level tank 300 is arranged at the other side of the mineralized water tank, and is separated from the mineralized water tank by a second porous partition. The low water level tank 300 is provided with a second overflow port. The height of the second overflow port is lower than the height of the first overflow port, and the height difference between the first overflow port and the second overflow port is adjustable to adjust the water level difference between the high water level tank and the low water level tank.

[0046] The first water storage tank 400 is arranged at the lower side of the high water level water tank 200, and is used to collect the mineralized water overflowing from the first overflow port. The second water storage tank 500 is arranged at the lower side of the low water level water tank 300, and is used to collect the mineralized water overflowing from the second overflow port. The second water storage tank 500 is connected to a water outlet pipe 720, and a water outlet solenoid valve or a water outlet valve is arranged on the water outlet pipe 720.

[0047] In this embodiment, a telescopic first overflow pipe 210 is vertically arranged at the bottom of the high water level water tank 200. The first overflow port is arranged at the top end of the first overflow pipe 210, and the bottom end opening of the first overflow pipe 210 is communicated with the first water storage tank 400. A telescopic adjusting device 220 is arranged in the high water level water tank 200 for controlling the telescopic movement of the first overflow pipe 210. A second overflow pipe 310 is vertically arranged at the bottom of the low water level water tank 300. The second overflow port is arranged at the top end of the second overflow pipe 310, and the bottom end opening of the second overflow pipe 310 is communicated with the second water storage tank 500. In other embodiments, the length of the second overflow pipe 310 can also be adjusted to achieve the purpose of adjusting the water level difference between the high water level water tank 200 and the low water level water tank 300.

[0048] A mineral detection component 610 is arranged in the second water storage tank 500 for detecting the mineral ion concentration of the mineralized water in the second water storage tank 500. Preferably, the mineral detection component 610 is a conductivity sensor. The inlet solenoid valve 711, the outlet solenoid valve, the telescopic adjusting device 220 and the mineral detection component 610 are all connected to the control system.

[0049] The working principle of the mineralization device is as follows: A certain water level difference is formed between the high water level water tank 200 and the low water level water tank 300. At the same time, under the action of capillary force on the water level line, a certain height of supporting capillary water zone will be formed in the porous medium. The supporting capillary water zone is composed of water, mineralized porous medium and air (containing carbon dioxide). In this way, on the one hand, the conditions for water-rock interaction (water, rock, carbon dioxide) are met. At the same time, since the porous medium wraps the air, the seepage path becomes longer, and the contact time between water and the porous medium also becomes longer, enhancing the intensity of water-rock interaction. Therefore, the mineralization effect of the porous mineralization medium 110 is improved. Based on the seepage law of water flow in unsaturated porous media, due to the different water level differences between the high water level water tank 200 and the low water level water tank 300, the seepage velocity of water flow in the porous mineralization medium 110 is also different, and the contact time and area between the water flow and the porous mineralization medium 110 are also different. Therefore, the height of the first overflow pipe 210 can be adjusted by the telescopic adjusting device 220, that is, by adjusting the water level difference between the high water level water tank 200 and the low water level water tank 300, so as to adjust the degree of mineralization and realize the adjustment of the mineral ion concentration.

[0050] Specifically, when the inlet solenoid valve 711 is opened and water enters the high-level water tank 200 through the inlet pipe 710, it then enters the low-level water tank 300 through the porous mineralization medium 110. When the water levels reach the heights of the first overflow pipe 210 of the high-level water tank 200 and the second overflow pipe 310 of the low-level water tank 300 respectively, the water flows into the first storage tank 400 and the second storage tank 500 respectively. At this time, a stable water level difference is formed between the high-level water tank 200 and the low-level water tank 300. Driven by the stable water heads of the high-level water tank 200 and the low-level water tank 300, the water undergoes lateral seepage in the porous mineralization medium 110 and flows into the second storage tank 500 through the second overflow pipe 310. Meanwhile, the mineral detection component 610 detects the mineral ion concentration in the second storage tank 500 and feeds it back to the control system. The control system controls the telescopic adjustment device 220 to adjust the height of the first overflow pipe 210. Specifically, when the mineral detection component 610 detects that the mineral concentration in the second storage tank 500 is greater than the set mineral concentration, the control system controls the telescopic adjustment device 220 to raise the height of the first overflow pipe 210 in the high-level water tank 200. The seepage rate of the water in the porous mineralization medium 110 increases, and the contact time and area between the water and the porous mineralization medium 110 become smaller, thereby reducing the mineral ion concentration entering the low-level water tank 300 and the second storage tank 500. When the mineral detection component 610 detects that the mineral concentration in the second storage tank 500 is less than the set mineral concentration, the control system controls the telescopic adjustment device 220 to lower the height of the first overflow pipe 210 in the high-level water tank 200. The seepage rate of the water in the porous mineralization medium 110 decreases, and the contact time and area between the water and the porous mineralization medium 110 become larger, thereby increasing the mineral ion concentration entering the low-level water tank 300 and the second storage tank 500. Through the above control method, the detected mineral concentration is maintained within the set mineral concentration range.

[0051] The above mineralization device controls the seepage rate of water in the porous mineralization medium 110 by adjusting the height difference between the high-level water tank 200 and the low-level water tank 300, and adjusts the mineral ion concentration in the mineralized water by controlling the surface area and time of contact between the water and the porous mineralization medium 110.

[0052] Furthermore, the first storage tank 400 is connected to the inlet pipe 710 through a circulation pipe 730, and the excess water can enter the first storage tank 400 again through the circulation pipe 730 for mineralization. A one-way valve 731 is provided on the circulation pipe 730.

[0053] A liquid level detection component 620 is also provided in the second water storage tank 500. The liquid level detection component 620 is used to detect the water level in the second water storage tank 500. The liquid level detection component 620 is preferably a liquid level sensor. When the mineralized water continuously enters the second water storage tank 500 until the liquid level sensor detects that the level in the second water storage tank 500 reaches a preset value, the water inlet solenoid valve 711 is closed.

[0054] In this embodiment, a porous end cap 120 is provided at the top of the mineralization tank 100. Air can enter the porous mineralization medium 110 through the porous end cap 120 to form a water-rock interaction. At the same time, an ultraviolet lamp 130 is further provided inside the porous end cap 120, which can sterilize the air entering the mineralization tank 100 to prevent the pollution of the mineralized water.

[0055] A first exhaust port and a second exhaust port for one-way outward exhaust are respectively provided on the first water storage tank 400 and the second water storage tank 500 for exhausting air from the water tanks. A first one-way exhaust valve 410 and a second one-way exhaust valve 510 are respectively provided on the first exhaust port and the second exhaust port.

[0056] The present invention also includes a method for adjusting the mineral concentration in the mineralized water for this mineralization device. The method includes:

[0057] S100, detecting the mineral concentration of the second water storage tank 500;

[0058] S200, adjusting the water level difference between the high water level tank 200 and the low water level tank 300 according to the set mineral concentration and the mineral concentration of the second water storage tank 500.

[0059] Specifically, in the step of adjusting the water level difference between the high water level tank 200 and the low water level tank 300 according to the set mineral concentration and the mineral concentration of the second water storage tank 500, it includes:

[0060] S210, when the mineral concentration of the second water storage tank 500 is greater than the set mineral concentration, raising the height of the first overflow pipe 210 in the high water level tank 200;

[0061] S220, when the mineral concentration of the second water storage tank 500 is less than the set mineral concentration, lowering the height of the first overflow pipe 210 in the high water level tank 200.

[0062] The present invention also includes a water purifier, which includes the above-mentioned mineralization device. The water purifier can use filters such as reverse osmosis membrane filtration and ultrafiltration membrane filtration. When this mineralization device is applied to a water purifier, it can perform quality-separated water supply by adjusting the degree of mineralization on the basis of considering the drinking water nutritional needs of infants and young children of different ages, pregnant women, and lactating mothers.

[0063] Since the mineral requirements of infants and young children of different ages, pregnant women, and lactating women for drinking water are different, the relationship between the conductivity and minerals such as calcium and magnesium after water flows through the porous mineralization medium 110 can be analyzed in advance. Then, according to the concentrations of minerals such as calcium and magnesium in the drinking water suitable for infants and young children of different ages, pregnant women, and lactating women, the mineral concentrations of the drinking water suitable for different groups of people can be set in the control system. After the control system receives the drinking water requirements of different groups of people, the height of the first overflow pipe 210 is adjusted by the conductivity signal output by the conductivity sensor in the second water storage tank 500. Water flows into the mineralization tank 100 through the water inlet pipe 710 until the water level sensor detects that the water volume in the second water storage tank 500 reaches the preset value, and then the water inlet solenoid valve 711 is closed.
