Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, specifically to a water circuit system, control method, and mineral water purifier for use in a mineral water purifier. Background Technology

[0002] With the improvement of productivity, people's demand for quality of life and convenience is also increasing. Mineralized water is widely favored as drinking water. At the same time, there is also a certain demand for mineralized water in production and experimental processes. Mineralized water can include alkaline and acidic mineralized water, and different types of mineralized water have different uses and effects.

[0003] Currently, there are two common methods for preparing mineralized water. The first is to artificially mix mineral salts with water to create mineralized water of suitable concentration. However, this method is cumbersome, requires a certain level of chemical knowledge, and is relatively inefficient. The second method involves adding mineralizing filter media to a container filled with water—such as a water dispenser or water purifier. The minerals in the filter media dissolve into the water, transforming it into mineralized water. However, most mineral salts are difficult to dissolve, and relying solely on the natural release of mineralizing filter media is insufficient to achieve the concentration required for water use, significantly impacting the usability of the mineralizing filter media.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] With the improvement of productivity, people's demand for quality of life and convenience is also increasing. Mineralized water is widely favored as drinking water. At the same time, there is also a certain demand for mineralized water in production and experimental processes. Mineralized water can include alkaline and acidic mineralized water, and different types of mineralized water have different uses and effects.

[0031] Currently, there are two common methods for preparing mineralized water. The first is to artificially mix mineral salts with water to create mineralized water of suitable concentration. However, this method is cumbersome, requires a certain level of chemical knowledge, and is relatively inefficient. The second method involves adding mineralizing filter media to a container filled with water—such as a water dispenser or water purifier. The minerals in the filter media dissolve into the water, transforming it into mineralized water. However, most mineral salts are difficult to dissolve, and relying solely on the natural release of mineralizing filter media is insufficient to achieve the concentration required for water use, significantly impacting the usability of the mineralizing filter media.

[0032] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0033] See Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 1 This is a schematic diagram of the water circuit structure of the first embodiment of the water circuit system for a mineral water purifier provided in this application. Figure 2 This is a schematic diagram of the water circuit structure of the second embodiment of the water circuit system for a mineral water purifier provided in this application. Figure 5This is a schematic diagram of the water circuit structure of the third embodiment of the water circuit system for a mineral water purifier provided in this application. Figure 6 This is a schematic diagram of the water circuit structure of the fourth embodiment of the water circuit system for a mineral water purifier provided in this application. Specific embodiments of this application provide a water circuit system for a mineral water purifier capable of processing input fluid. The water circuit system for the mineral water purifier includes alkaline filter media 1, acidic filter media 2, and a mineralization water circuit 32.

[0034] In this process, alkaline filter media 1 and acidic filter media 2 are sequentially arranged in the mineralization water path 32. Alternatively, acidic filter media 2 and alkaline filter media 1 are sequentially arranged in the mineralization water path 32. At least one of alkaline filter media 1 and acidic filter media 2 is a mineralization filter media, capable of dissolving minerals into the water.

[0035] In the structure provided in this specific embodiment, alkaline filter media 1 and acidic filter media 2 are simultaneously provided in the mineralized water path 32. The acidic filter media 2 can promote the release of minerals in the alkaline filter media 1 by using acidic substances released by the acidic filter media 2, or promote the release of minerals in the acidic filter media 2 by using alkaline substances released by the alkaline filter media 1. It can also adjust the alkaline water flowing through the alkaline filter media 1 and the acidic water flowing through the acidic filter media 2, thereby using alkaline water with different pH values ​​and acidic water to prepare mineralized water with a moderate pH value that meets the usage requirements for use. This can reduce the probability that the mineral content of the final water output from the water system of the mineral water purifier is too low, and can improve the safety and stability of the water system of the mineral water purifier.

[0036] For example, the alkaline filter material 1 may include at least one of brucite, periclase, calcite, and dolomite. The acidic filter material 2 may include at least one of diopside, serpentine, and maifanite. In this case, the acidic filter material 2 is a mineralizing filter material. Under the promotion of the alkaline substances dissolved from the alkaline filter material 1, the acidic filter material 2 can dissolve metasilicic acid into the water, thereby producing metasilicic acid mineralized water with sufficient mineral content.

[0037] Metasilicic acid (H2SiO3) can be produced by the hydrolysis of silicate ores in water. Taking sodium silicate (Na2SiO3) as an example, the reaction formula for the hydrolysis of sodium silicate to produce metasilicic acid is as follows:

[0038] Reaction 1:

[0039] Reaction 2:

[0040] The dynamic equilibrium between metasilicic acid and orthosilicic acid (H4SiO4) exists. Orthosilicic acid is strongly acidic and can exist stably in an acidic environment. Therefore, a suitable alkaline environment can shift the equilibrium of reaction two to the left, i.e., reaction two proceeds in reverse, resulting in a decrease in orthosilicic acid content and an increase in metasilicic acid content. Based on this principle, the alkaline filter material can promote the dissolution of metasilicic acid in the acidic filter material 2, thereby reducing the probability of the final water output from the water system of the mineral water purifier having excessively low mineral content, and improving the safety and stability of the water system used in the mineral water purifier.

[0041] However, excessive alkalinity can inhibit the forward reaction of reaction one, suppress the hydrolysis of silicate ions, and thus inhibit the formation of metasilicic acid. Several embodiments were obtained by adjusting the mass ratio of alkaline filter material 1 to metasilicic acid filter material. For each embodiment, the pH value of the flowing water, the metasilicic acid concentration in the flowing water, and the metasilicic acid concentration in the soaking water after soaking for 1 hour were tested, and the results are shown in Table 1 below.

[0042] Table 1

[0043]

[0044] Referring to the data in Table 1, in the embodiment where the mass percentage of alkaline filter media 1 is 0%, the outflow water is weakly acidic, and the metasilicic acid concentration in the outflow water is very low, only 0.2 mg / L. When the mass percentage of alkaline filter media 1 increases to 10%, the metasilicic acid concentration in the outflow water increases, reaching 1.2 mg / L. When the mass percentage of alkaline filter media 1 is between 20% and 40%, the metasilicic acid concentration in the outflow water reaches above 2 mg / L. When the mass percentage of alkaline filter media 1 is 30%, the metasilicic acid concentration in the soaking water can reach a maximum of 10 mg / L. Furthermore, when the mass percentage of alkaline filter media 1 is 50%, the pH value of the outflow water is too high, while the metasilicic acid concentrations in both the outflow water and the soaking water decrease. It can be observed that at this point, the effect of alkaline substances in promoting metasilicic acid formation begins to decrease.

[0045] Optionally, such as Figure 1 , Figure 2 As shown, the water system may further include a second return water path 35, a second drainage branch 36, a pre-inlet water path 37, a return valve 42, an inlet valve 43, a wastewater valve 44, and a pump body 7. The second return water path 35 is connected at one end to the inlet water path and at the other end to the input end of the water purification component 6. The return valve 42 is connected to the second return water path 35. The pre-inlet water path 37 connects to an external water source and the input end of the water purification component 6. The pump body 7 and the inlet valve 43 are connected to the pre-inlet water path 37, allowing the water in the entire water system to flow under the drive of the pump body 7. The second drainage branch 36 connects to the wastewater outlet of the water purification component 6, used to discharge the wastewater generated during the water purification process of the water purification component 6 to the outside. The wastewater valve 44 is connected to the drainage branch.

[0046] In one specific embodiment, an anti-backflow device 8 is connected between the alkaline filter media 1 and the acidic filter media 2. The anti-backflow device 8 is used to prevent water flowing through the alkaline filter media 1 from flowing back to the acidic filter media 2, or the anti-backflow device 8 is used to prevent water flowing through the acidic filter media 2 from flowing back to the alkaline filter media 1.

[0047] In the structure provided in this specific embodiment, when the mineral water purifier stops, the water in the water system may lose its power. At this time, the water no longer flows along the preset water flow direction under drive, but flows freely and irregularly in the water system. If there is no anti-backflow device 8, the water in the alkaline filter media 1 and the acidic filter media 2 will flow into each other, causing the alkaline filter media 1 and the acidic filter media 2 to continuously consume each other, and easily causing the mineral content or pH value of the water in the water system to exceed the standard, which will have a significant impact on the service life of the water system.

[0048] Therefore, by setting up the anti-backflow device 8, the water in the mineralized water path 32 can be prevented from flowing backward, thereby avoiding the meaningless consumption of the alkaline filter material 1 and the acidic filter material 2, extending the service life of the water system, and improving the availability of the water system.

[0049] In one specific embodiment, the water system includes a post-inlet water channel 31, a pure water channel 33, and an outlet water channel 34. The post-inlet water channel 31 is connected to the pure water channel 33 and the mineralized water channel 32. The ends of the pure water channel 33 and the mineralized water channel 32 that are away from the post-inlet water channel 31 are both connected to the outlet water channel 34.

[0050] In the structure provided in this specific embodiment, the purified water output from the pure water path 33 and the mineralized water output from the mineralized water path 32 can be mixed and then output through the water outlet path 34, thereby further adjusting the mineralized water. This can reduce the probability that the final water output from the water system of the mineral water purifier has an excessively high mineral content, and can improve the safety and stability of the water system of the mineral water purifier.

[0051] Optionally, the water system also includes a first diversion valve 41, which is connected to and placed into water path 31, pure water path 33 and mineralized water path 32.

[0052] In the structure provided in this specific embodiment, the first diversion valve 41 can control the amount of water input into the pure water path 33 and the mineralized water path 32 through the rear water path 31, thereby controlling the ratio of mineralized water to pure water when water is discharged from the outlet path 34. This further adjusts the mineralized water, reducing the probability of excessively high mineral content in the final water output of the water system used in the mineral water purifier, and improving the safety and stability of the water system used in the mineral water purifier.

[0053] Optionally, the water system also includes a first flow valve and a second flow valve, the first flow valve being connected to the pure water circuit 33 and the second flow valve being connected to the mineralized water circuit 32.

[0054] The structure provided in this specific embodiment can control the opening and closing of the first flow valve and the second flow valve, thereby controlling the flow rate and velocity of the mineralized water flowing out through the mineralized water path 32 and the purified water flowing out through the pure water path 33. This allows for the control of the ratio of mineralized water to purified water flowing into the water path 34, enabling further adjustment of the mineralized water and improving the safety and stability of the water system used in the mineral water purifier.

[0055] In one specific embodiment, the main body of the device also includes a first water quality detection element 51 and a controller, wherein the first water quality detection element 51 and the first diversion valve 41 are both connected to the controller. The first water quality detection element 51 is disposed in the mineralized water channel 32 and is located behind the alkaline filter material 1 and the acidic filter material 2 in a preset water flow direction.

[0056] Optionally, the first water quality testing device 51 is installed in the water outlet 34.

[0057] In the structure provided in this specific embodiment, the first water quality detection element 51 set in the water outlet 34 can intuitively characterize the final water quality when the water is discharged. The first water quality detection element 51 set in the mineralized water channel 32 can measure the water quality of the mineralized water. Based on the water quality of the mineralized water, the ratio of mineralized water and purified water required to adjust to a specified mineral content range can be calculated.

[0058] Therefore, by setting the first water quality detection device 51, the water quality of the water body in the water system can be effectively monitored. This allows the controller to adjust at least one of the valves, such as the first diversion valve 41, the first flow valve, and the second flow valve, based on the water quality feedback. This improves the accuracy of the water system in regulating the mineral content of the output water, enabling the water system to output water that better meets the user's needs and enhancing the availability of the water system.

[0059] In one specific embodiment, the main body of the device further includes a first flow detection element 53, which is disposed in at least one of the downstream water passage 31, the mineralized water passage 32, and the purified water passage 33, and is connected to a controller. The first flow detection element 53 can monitor the amount of water passing through the mineralized water passage 32 and even the entire water passage system, thereby monitoring the service life of the water passage system. In conjunction with the first water quality detection element 51, it can effectively monitor the working effect of the water passage system at different stages of use, thereby improving the availability of the water passage system.

[0060] In one specific embodiment, the first water quality detection element 51 is disposed in the mineralization water channel 32 and located behind the alkaline filter media 1 and the acidic filter media 2 in a preset water flow direction. The main body of the equipment also includes a second diversion valve, which is connected to a controller and is connected in the mineralization water channel 32, located behind the first water quality detection element 51 in the preset water flow direction. The main body of the equipment also includes a first drainage branch 39 and a wastewater outlet, with one end of the first drainage branch 39 connected to the second diversion valve and the other end connected to the wastewater outlet.

[0061] In the structure provided in this specific embodiment, the first drainage branch 39 can be used in conjunction with the second diversion valve to input the portion of water in the mineralized water path 32 that meets the usage requirements into the water outlet path 34, and to discharge the portion of water that does not meet the usage requirements to the outside, thereby reducing problems such as excessive water output, pH value exceeding the standard, and pH value being too low in the water outlet path 34, and improving the availability of the water system.

[0062] In one specific embodiment, the main body of the device further includes a second water quality detection element 52 and a water purification component 6. The output end of the water purification component 6 is connected to the end of the rear water inlet channel 31 away from the first diversion valve 41. The second water quality detection element 52 is disposed in the rear water inlet channel 31 and is connected to the controller.

[0063] Among them, the first water quality testing component 51 and the second water quality testing component 52 are at least one of the TDS value testing component and the pH value testing component.

[0064] In the structure provided in this specific embodiment, the second water quality detection device 52 can detect the water quality in the water path 31 after the water purification component 6 is input, thereby monitoring the water quality before the water is input into the alkaline water path, realizing the prediction and calculation of the mineral content of the water output from the water path 34, and improving the availability of the water path system.

[0065] Among them, the pH sensor is used to detect the hydrogen ion concentration in the analyte and convert it into a corresponding usable output signal, thereby characterizing the pH value of the water. Since both acidic and alkaline filter cartridges affect the pH value of the water, the mineral content in the water can be estimated based on the pH value. The TDS sensor is a device used to measure the total dissolved solids (TDS) in water. It can continuously monitor the conductivity value of the analyte, and the mineral content in the analyte can be calculated based on the conductivity value, thus characterizing the mineral content of the water.

[0066] In one specific embodiment, the main body of the device is further provided with a first return water path 38, which is connected to the water purification component 6. The main body of the device also includes a third diversion valve, which is connected to the pure water path 33 and the end of the first return water path 38 away from the water purification component 6.

[0067] Optionally, the main body of the device also includes a fourth diversion valve, which is connected to the rear water inlet 31 and located behind the second water quality detection element 52 in the preset water flow direction. The fourth diversion valve is also connected to the end of the first return water inlet 38 away from the water purification component 6.

[0068] In the structure provided in this specific embodiment, the first return water path 38 can be used to return water in the pure water path 33 to the water purification component 6, thereby reducing the probability of excessive purified water leading to low mineral content in the output water and avoiding waste of purified water. At the same time, the first return water path 38 can also return purified water that does not meet the usage standards to the water purification component 6 for further filtration, thereby reducing the probability of substandard water quality in the output water path 34.

[0069] In one specific embodiment provided in this application, the main body of the device may further include a communication component connected to the controller. The communication component can be used to receive water quality control messages, and the controller can control the water system according to the water quality control messages, thereby outputting water that conforms to the water quality control messages through the outlet channel 34.

[0070] This application also provides a mineral water purifier, including a water outlet component and a water circuit system for the mineral water purifier as described in any of the above embodiments. The water outlet component is used to dissipate water to the outside environment and is connected to the water outlet path 34 of the water circuit system of the mineral water purifier.

[0071] In the structure provided in this specific embodiment, alkaline filter media 1 and acidic filter media 2 are simultaneously provided in the mineralized water path 32. The acidic filter media 2 can promote the release of minerals in the alkaline filter media 1 by using acidic substances released by the acidic filter media 2, or promote the release of minerals in the acidic filter media 2 by using alkaline substances released by the alkaline filter media 1. It can also adjust the alkaline water flowing through the alkaline filter media 1 and the acidic water flowing through the acidic filter media 2, thereby using alkaline water with different pH values ​​and acidic water to prepare mineralized water with a moderate pH value that meets the usage requirements for use. This can reduce the probability that the mineral content of the final water output from the water system of the mineral water purifier is too low, and can improve the safety and stability of the water system of the mineral water purifier.

[0072] This application also provides a control method for a mineral water purifier, see below. Figure 3 , Figure 3 This is a flowchart illustrating an embodiment of a control method for a mineral water purifier. It should be noted that if substantially the same result is achieved, this embodiment is not necessarily identical. Figure 3 The illustrated process sequence is limited. For example... Figure 3 As shown, the control method for this mineral water purifier may include:

[0073] S100: Receive water quality control messages.

[0074] S200: In response to a water quality control message, control the first diversion valve 41 to adjust the flow ratio of the input mineralized water path 32 and the pure water path 33.

[0075] The execution subject of the control method for the mineral water purifier provided in this application can be a controller for the water circuit system of the mineral water purifier. The controller is connected to the first diversion valve 41 and can receive water quality control messages, thereby controlling the water quality of the water body output from the outlet water circuit 34 by adjusting the flow ratio of the input mineralized water circuit 32 and the pure water circuit 33.

[0076] The water quality control message can be generated locally on the mineral water purifier device, for example, by the user inputting a command into the mineral water purifier through a keypad operation to generate the corresponding water quality control message. Alternatively, it can be generated on the client side, where the client and the mineral water purifier are connected via a communication component. The communication component receives the water quality control message generated and sent by the client and transmits it to the controller.

[0077] See Figure 4 , Figure 4 This is a flowchart illustrating another embodiment of the control method for a mineral water purifier. It should be noted that if substantially the same result is achieved, this embodiment is not necessarily identical. Figure 4 The illustrated process sequence is limited. For example... Figure 4 As shown, the control method for this mineral water purifier may also include:

[0078] S300: Obtain the total flow parameter from the first flow detection element 53, and determine whether the total flow parameter is greater than or equal to the first threshold.

[0079] S400: In response to the total flow parameter being greater than or equal to the first threshold, the first diversion valve 41 is controlled to adjust the flow rate of the input pure water circuit 33 to zero, the flow rate of the input mineralized water circuit 32 is adjusted to the maximum, and the water quality parameter is obtained from the first water quality detection device 51.

[0080] S500: Determines whether the water quality parameter is less than the second threshold.

[0081] S600: In response to the water quality parameter being less than the second threshold, a filter replacement message is generated and sent using the communication component.

[0082] The method provided in this specific embodiment enables the monitoring of the lifespan of the water system using the total flow parameter measured by the first flow detection element 53. Furthermore, when the total flow parameter is greater than or equal to a first threshold, the water system is promptly adjusted to output water only from the mineralization water path 32. This allows for the determination of whether the alkaline and acidic filter cartridges are still functioning properly to prepare mineralized water based on water quality parameters. When the alkaline or acidic filter cartridges malfunction, a filter replacement message is sent to the user, significantly improving the usability of the mineral water purifier.
