The outlet end of the base liquid inlet main pipe 1 is connected to the inlet end of the preliminary purification assembly, the outlet end of the preliminary purification assembly is connected to the inlet end of the purified water main pipe 4, and the outlet end of the purified water main pipe 4 is respectively connected with a semi-finished product branch pipe 101 and a finished product branch pipe 102, wherein the end of the semi-finished product branch pipe 101 away from the purified water main pipe 4 is connected with a mineral precipitation filter tank 5, and the end of the finished product branch pipe 102 away from the purified water main pipe 4 is connected with a finished product solution tank 11. Moreover, the mineral precipitation filter tank 5 is provided with natural minerals, the natural minerals include one or more of rhyolite, tourmaline, wax stone, perlite, wood fish stone, lapis lazuli, feldspar, iron ore, opal, germanium stone, calcite, quartz stone, zeolite, mica, talc, garnet, manganese sand and clinoptilolite, when the purified water enters the mineral precipitation filter tank 5, it will contact with the natural minerals, the minerals are dissolved in the purified water in the form of ions, the mineral content in the water is increased, and the PH value is also increased. The outlet end of the mineral precipitation filter tank 5 is connected with a semi-finished product filtration assembly, the mineral water flowing out of the mineral precipitation filter tank 5 is filtered by the semi-finished product filtration assembly, so that it can be directly drunk. The outlet end of the semi-finished product filtration assembly is connected with the inlet end of the finished product solution tank 11 through a semi-finished product solution outlet pipe 10, and the outlet end of the finished product solution tank 11 is connected with a finished product solution outlet pipe 12.

[0030] Before actual use, the natural minerals are crushed to a certain diameter of small particles in the factory and are pre-added to the mineral precipitation filter tank 5. Then during actual use, the base liquid from the semi-finished product branch pipe 101 is added to the mineral precipitation filter tank 5, when the purified water flows through the mineral precipitation filter tank 5, the PH value and the water flow are monitored in real time, and the controller calculates the amount of purified water and semi-finished product solution that needs to be added, so that all the finished product solution tanks 11 are filled. Since the mineral precipitation filter tank 5 is already filled with water, and the finished product water will not be used up immediately, this time will make the mineral concentration in the mineral precipitation filter tank 5 tend to saturation, at this time the PH value in the mineral precipitation filter tank 5 is monitored, when one of the finished product solution tanks 11 is used up, the controller calculates the amount of purified water and semi-finished product solution that needs to be injected, and the finished product solution tank 11 is filled for standby. Similarly, when another finished product solution tank 11 is used up, it is also filled, and the process is repeated.

[0031] In the embodiment, two finished solution tanks 11 are provided. When the two finished solution tanks 11 are full, the output is alternated and the replenishment is alternated to ensure the continuity of water supply. When the first finished solution tank 11 is used up, the output is switched to the second finished solution tank 11, and at the same time, a certain amount of semi-finished solution and base solution are injected into the first finished solution tank 11 according to the calculation of the controller, and the first finished solution tank 11 is filled with the semi-finished solution and the base solution for standby use; when the second finished solution tank 11 is used up, the output is switched to the first finished solution tank 11, and at the same time, a certain amount of semi-finished solution and base solution are injected into the second finished solution tank 11 according to the calculation of the controller, and the second finished solution tank 11 is filled with the semi-finished solution and the base solution for standby use. This is repeated, so that the two finished solution tanks 11 can alternately output, ensuring that the water supply can be continuous and stable.

[0032] In the embodiment, the tap water from the tap water source is first subjected to a preliminary filtration by the preliminary purification assembly, and then is transported to the subsequent pipeline through the purified water main 4. The preliminary purification assembly includes a preliminary first filter device 2 and a preliminary second filter device 3 arranged in sequence, wherein the tap water first passes through the preliminary first filter device 2 and then passes through the preliminary second filter device 3. The preliminary first filter device 2 includes a PP cotton filter core and a filter shell for fixing the PP cotton filter core, and the preliminary second filter device 3 includes a nanofiltration membrane filter core and a filter shell for fixing the nanofiltration membrane filter core. The preliminary purification assembly is arranged to convert the tap water into nanofiltration purified water, reduce the amount of wastewater discharge, and reduce the consumption of minerals in natural minerals.

[0033] In the embodiment, the mineral precipitation filter tank 5 is provided with a filter bag, and the pore size of the filter bag is smaller than the particle diameter of the natural minerals, so that the natural minerals placed in the filter bag will not be washed out of the mineral precipitation filter tank 5 by the water flow. When the precipitated minerals reach the lower limit of use, the filter bag containing the mineral powder can be simply replaced with a new one, which is simple and convenient to operate.

[0034] In the embodiment, the semi-finished product filtration assembly includes a first-level filter device 6, a second-level filter device 7, a third-level filter device 8, and a fourth-level filter device 9 connected in sequence by pipe fittings. The four layers of filtration can effectively remove impurities and odors in mineral water, making it convenient for users to directly drink.

[0035] The four layers of filtration system are as follows: the filter core of the first-level filter device 6 is a PP cotton filter core, the filter core of the second-level filter device 7 is an ultrafiltration filter core, the filter core of the third-level filter device 8 is a coconut shell activated carbon filter core, and the filter core of the fourth-level filter device 9 is a folded membrane filter core. Of course, in addition to the filter core, the first-level filter device 6, the second-level filter device 7, the third-level filter device 8, and the fourth-level filter device 9 also include their independent shell structures, and the shell structures are conventional filter housings, which will not be described here.

[0036] In the embodiment, the PH meter is arranged in the mineral precipitation filter tank 5 and the finished solution tank 11, and the PH meter is electrically connected with the controller. The PH meter is used for monitoring the PH value in the mineral precipitation filter tank 5 and the finished solution tank 11 respectively, and transmitting the PH value to the controller. The controller determines the amount of the semi-finished solution and the amount of the base solution needed to be added into the finished solution tank 11 according to the obtained PH value and the PH value of the finished solution set by the user.

[0037] It is to be noted that the controller includes, but is not limited to, the existing single-chip microcomputer controller, PLC controller and the like.

[0038] In the embodiment, the liquid level sensor is arranged in the finished solution tank 11, and the liquid level sensor is electrically connected with the controller. When the solution in the finished solution tank 11 reaches the lower limit of the liquid level, the controller switches to output the finished solution from another finished solution tank 11, and at the same time, the finished solution tank 11 reaching the lower limit of the liquid level is filled with the solution for standby.

[0039] In the embodiment, the electrically controlled valve is arranged on the base solution inlet main pipe 1, the semi-finished solution branch pipe 101, the finished solution branch pipe 102, the semi-finished solution outlet pipe 10 and the finished solution outlet pipe 12, and the electrically controlled valve is electrically connected with the controller. The controller controls the opening or closing of each pipe.

[0040] In the embodiment, the flow meter (or flow sensor) is arranged on the finished solution branch pipe 102 and the semi-finished solution outlet pipe 10. The controller can calculate the amount of the solution needed to be added into the mineral precipitation filter tank 5 or the finished solution tank 11 according to the PH value measured by the PH meter. The flow meter arranged on each pipe is used for detecting the flow of the solution, and feeding back the measured data to the controller. The controller accurately controls each valve to obtain the accurate amount of the added base solution and / or semi-finished solution, so as to obtain the mineral water with the customized PH value.
