It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] With the improvement of living quality, people have higher and higher requirements for drinking water, hoping that the water purified by the water purification system can contain minerals that are beneficial to the human body. Therefore, products that use mineralization filters to mineralize purified water are born.

[0030] However, in the related art, when the user does not use water, although the water in the water purification system is no longer output, the mineralized filter element is still immersed in the water, so that the minerals will continue to dissolve into the water. In addition, the water in the mineralized filter element is still connected to the water path of the entire water purification system, so that the minerals in the mineralized filter element will diffuse from the mineralized filter element to the water path of the entire water purification system, causing the water path of the water purification system to exceed the mineral content. As a result, the user will take out a large amount of wastewater with excessive minerals when taking water next time, and the continuous immersion and dissolution will also seriously affect the service life of the mineralized filter element.

[0031] In order to improve or solve the above technical problems, the inventors of the present application have proposed at least the following embodiments after long-term research.

[0032] See also Figure 1 , Figure 1 The schematic diagram of the water channel structure of an embodiment of the water channel system for a mineral water purifier provided by the present application. To solve the above technical problems, the specific implementation of the present application can provide a water channel system for a mineral water purifier for treating water.

[0033] The water system for a mineral water purifier may include a mineralized filter material 1, a water purifier 2, a water outlet 33, a return water path 34, a first control valve 41, and a first water quality detection component 51, wherein the first control valve 41 is connected to the water outlet 33. In a preset water flow direction, the water purifier 2, the mineralized filter material 1, and the water outlet 33 are connected in sequence. The return water path 34 connects the input end of the water purifier 2 and the water outlet 33 upstream of the first control valve 41. The first water quality detection component 51 is connected to the water outlet 33 and is located upstream of the first control valve 41.

[0034] In the structure provided in this specific embodiment, by providing a first water quality detection component 51, a first control valve 41 and a return water path 34, the first water quality detection component 51 can be used to detect the mineral content of the water in the mineralized filter material 1. When it is detected that the mineral content is too high, the first control valve 41 can be closed to stop the water from being discharged to the outside through the water outlet path 33. The water subsequently input into the mineralized filter material 1 can be used to replace the water with excessively high mineral content in the mineralized filter material 1, so that the water with excessively high mineral content can flow into the water purification device 2 through the return water path 34, and be purified again by the water purification device 2 to remove the minerals with excessively high content therein, thereby effectively solving the problem of excessively high mineral content in the water output from the water outlet path 33.

[0035] In a specific embodiment of the present application, the water system for the mineral water purifier may further include a second water quality detection component 52, a controller and a pump body 6. The second water quality detection component 52 is connected to the return waterway 34, and the first water quality detection component 51, the second water quality detection component 52, and the first control valve 41 are connected to the controller. The pump body 6 is used to pump the water of the mineralized filter material 1 into the water purification device 2 through the return waterway 34, and the pump body 6 is connected to the controller.

[0036] In the structure provided in this specific embodiment, the second water quality detection component 52 can be used to monitor the mineral content of the flushing water flushed from the mineralized filter material 1. When the mineral content in the flushing water drops to meet the standard, it means that the mineralized filter material 1 is able to output water that meets the standard to the water outlet 33, and thus the timing to stop flushing the mineralized filter material 1 can be accurately determined. This can avoid serious life loss of the mineralized filter material 1 due to too long flushing time, and avoid the mineral content of the water output to the water outlet 33 being too high due to too short flushing time, and can effectively improve the stability and availability of the water system used for the mineral water purifier.

[0037] See also Figure 2 By adopting the water system for a mineral water purifier as provided in this specific embodiment and taking the device end of the mineral water purifier as the execution body, a control method for the mineral water purifier can be provided. Figure 2 This is a flowchart of an embodiment of the control method of a mineral water purifier provided in this application. It should be noted that if there is substantially the same result, this embodiment is not based on Figure 2 The process sequence shown is limited. Figure 2 As shown, the control method of the mineral water purifier may include:

[0038] S100: receiving the first water quality detection data sent by the first water quality detection component 51, and determining whether the first water quality detection data is qualified.

[0039] S200 : In response to the first water quality detection data being unqualified, closing the first control valve 41 and continuing to pass water into the mineralized filter material 1 .

[0040] The first water quality test data can be used to determine when to start flushing the mineralized filter material 1. For example, when the first water quality test data includes a mineral content exceeding a specified threshold, it can be determined that the first water quality test data is unqualified, and the mineralized filter material 1 can be flushed.

[0041] S300: receiving the second water quality detection data sent by the second water quality detection component 52, and determining whether the second water quality detection data is qualified.

[0042] S400: In response to the second water quality detection data being qualified, opening the first control valve 41 and / or stopping the flow of water into the mineralized filter material 1 .

[0043] The second water quality test data can be used to determine when to stop flushing the mineralized filter material 1. For example, when the second water quality test data includes that the mineral content is lower than a specified threshold, the second water quality test data can be determined to be qualified, and flushing the mineralized filter material 1 can be stopped.

[0044] In a specific embodiment of the present application, the water system for a mineral water purifier also includes a third water quality detection component 53, a drainage waterway 35, a rear-placed waterway 32, and a second control valve 42. The rear-placed waterway 32 connects the water purification device 2 and the mineralized filter material 1. The second control valve 42 and the third water quality detection component 53 are connected to the rear-placed waterway 32. The second control valve 42 and the third water quality detection component 53 are connected to the controller. The water purification device 2 is provided with a water inlet and a pure water outlet, the water inlet is used to connect to a water source, and the pure water outlet is connected to the rear-placed waterway 32. One end of the drainage waterway 35 is connected to the rear-placed waterway 32 upstream of the second control valve 42, and the other end of the drainage waterway 35 is connected to the water inlet.

[0045] In the structure provided in this specific embodiment, by setting the third water quality detection member 53, the water quality of the water body input into the mineralized filter material 1 through the rear-placed waterway 32 can be detected, and the water quality of the water body output from the water purification device 2 can be monitored, so as to determine whether the water body in the rear-placed waterway 32 is fully purified. When the water quality of the water body in the rear-placed waterway 32 is unqualified, that is, when the water body in the rear-placed waterway 32 is not fully purified, the water body in the rear-placed waterway 32 can be drained to the water inlet by the drainage waterway 35, so that this part of the water body can be filtered by the water purification device 2 again, which can effectively improve the stability and availability of the waterway system for the mineral water purifier.

[0046] See also Figure 3 By adopting the water system for a mineral water purifier as provided in this specific embodiment and taking the device end of the mineral water purifier as the execution body, a control method for the mineral water purifier can be provided. Figure 3The control method of the mineral water purifier provided in this application is a flowchart of an embodiment of the water body returning from the rear water channel. It should be noted that if there is substantially the same result, this embodiment is not based on Figure 3 The process sequence shown is limited. Figure 3 As shown, the control method of the mineral water purifier may include:

[0047] S500: receiving the third water quality detection data sent by the third water quality detection component 53, and determining whether the third water quality detection data is qualified.

[0048] S600 : In response to the third water quality detection data being unqualified, the second control valve 42 is closed, and the third control valve 43 is controlled to connect the reflux waterway 34 and the drainage waterway 35 .

[0049] In a specific embodiment of the present application, the water system for a mineral water purifier may further include a front waterway 31 and a third control valve 43. One end of the front waterway 31 is connected to the water inlet, and the other end of the front waterway 31 is used to connect to a water source. The third control valve 43 is connected to the return waterway 34, and the third control valve 43 is also connected to one end of the drainage waterway 35 away from the front waterway 31, and one end of the return waterway 34 away from the water outlet 33 is connected to the front waterway 31. Among them, the third control valve 43 signal is connected to the controller.

[0050] In the structure provided in this specific embodiment, specifically, the front water inlet 31 can be used to input water into the water purifier 2, and the return waterway 34 can be connected to the front water inlet 31, so that the water in the return waterway 34 can be input into the water inlet of the water purifier 2 along the front water inlet 31. And by setting the third control valve 43, the drainage waterway 35 can be connected to the return waterway 34, so that the water in the drainage waterway 35 can flow into the water purifier 2 through the return waterway 34, and the third control valve 43 can effectively control the connection and disconnection of the return waterway 34 and the drainage waterway 35, and thus can effectively control the flow of water in the waterway system for the mineral water purifier.

[0051] In a specific embodiment of the present application, the water system for the mineral water purifier may further include a fourth water quality detection component 54. The fourth water quality detection component 54 is connected to the front waterway 31, and the fourth water quality detection component 54 is located downstream of the end of the return waterway 34 connected to the front waterway 31. The fourth water quality detection component 54 signal is connected to the controller.

[0052] In the structure provided in this specific embodiment, by arranging the fourth water quality detection component 54 in the front water channel 31, the detection result of the fourth water quality detection component 54 can be compared with the detection result of the third water quality detection component 53. For example, the detection result of the fourth water quality detection component 54 is subtracted from the detection result of the third water quality detection component 53 to monitor the water quality of the water body output from the water purification device 2, so as to determine whether the water body in the rear water channel 32 is purified, which can effectively improve the stability and availability of the water system used for the mineral water purifier.

[0053] See also Figure 4 By adopting the water system for a mineral water purifier as provided in this specific embodiment and taking the device end of the mineral water purifier as the execution body, a control method for the mineral water purifier can be provided. Figure 4 This is a flowchart of another embodiment of the control method of the mineral water purifier provided by the present application, which is to return the water body from the rear into the waterway. It should be noted that if there is substantially the same result, this embodiment is not used. Figure 4 The process sequence shown is limited. Figure 4 As shown, the control method of the mineral water purifier may include:

[0054] S501 : receiving the third water quality detection data sent by the third water quality detection component 53 , and receiving the fourth water quality detection data sent by the fourth water quality detection component 54 .

[0055] S502: Calculate the difference between the third water quality detection data and the fourth water quality detection data, and determine whether the difference is qualified.

[0056] S601 : In response to the difference being unqualified, the second control valve 42 is closed, the third control valve 43 is controlled to connect the return water path 34 and the drainage water path 35 , and the pump body 6 is started.

[0057] When the difference is unqualified, for example, the difference is less than the specified threshold, it means that the water purification device 2 cannot fixedly remove impurities of the specified threshold from the water body, and further reflects that the water purification device 2 does not have the preset impurity removal effect, that is, the water purification device 2 cannot effectively purify the water body. The drainage waterway 35 can be used to return the water output by the water purification device 2 to the water purification device 2 for repeated purification, so as to achieve the expected water purification effect through multiple purifications.

[0058] In a specific embodiment of the present application, the water system for the mineral water purifier may further include a first wastewater channel 36 , and the water purifier 2 is further provided with a concentrated water outlet, and the first wastewater channel 36 is connected to the concentrated water outlet.

[0059] When there is a problem with the water purification effect of the water purification device 2, it may be due to problems with the structures used to filter the purified water, such as the filter body and / or filter membrane in the water purification device 2, for example, the surface of these structures is covered with impurities, resulting in the inability to effectively filter out impurities in the water body. In the structure provided in this specific embodiment, by setting the first wastewater path 36 and the concentrated water outlet, the reflux water in the reflux water path 34 and the unfiltered water body input from the outside into the water path 31 can be used to flush the structure used to filter the purified water, and this part of the flushing water is discharged into the first wastewater path 36 through the concentrated water outlet, and then discharged to the outside through the first wastewater path 36, so as to achieve the cleaning of the water purification device 2, so that the water purification device 2 can be restored to the state of normal filtering of the water body, which can effectively improve the stability and availability of the water system used for the mineral water purifier.

[0060] In a specific embodiment of the present application, the water system for the mineral water purifier also includes a fifth water quality detection component 55, the fifth water quality detection component 55 is connected to the first wastewater path 36, and the signal of the fifth water quality detection component 55 is connected to the controller.

[0061] In the structure provided in this specific embodiment, by setting the fifth water quality detection component 55 in the first waste water channel 36, the water quality of the flushing water of the flushing water purification device 2 can be detected, so that when the water quality of the flushing water meets the preset standard, the process of flushing the water purification device 2 can be stopped, thereby reducing the consumption of flushing water while ensuring the water purification effect of the water purification device 2, and minimizing the impact of flushing on the service life of the water purification device 2, thereby effectively improving the availability of the water system used for the mineral water purifier.

[0062] In a specific embodiment of the present application, the water system for the mineral water purifier further includes an air valve. The air valve is disposed in at least one of the rear-inserted waterway 32 and the mineralized filter material 1 downstream of the second control valve 42, and the air valve is used to connect the mineralized filter material 1 and the atmosphere.

[0063] In the structure provided in this specific embodiment, if the mineral content of the water in the mineralized filter material 1 does not meet the standard, the second control valve 42 can be closed, and the mineralized filter material 1 and even part of the water placed in the water path 32 can be pumped into the return water path 34 by the pump body 6 to flow back to the water purification device 2 for re-filtration. While not outputting the water with unqualified mineral content through the water outlet 33, the mineralized filter material 1 can be prevented from continuing to be immersed in the water body, causing the minerals to continue to dissolve, thereby affecting the service life of the mineralized filter material 1.

[0064] At the same time, due to the setting of the air valve, in the process of extracting the mineralized filter material 1 or even part of the water inserted into the water channel 32, the air valve can introduce gas into the mineralized filter material 1 and part of the water inserted into the water channel 32, so that there will be no obvious air pressure difference between the outside and the mineralized filter material 1, which can reduce the probability of water flowing back into the mineralized filter material 1, and can also reduce the residual water in the mineralized filter material 1, thereby improving the stability of the water system used for the mineral water purifier.

[0065] See also Figure 5 By adopting the water system for a mineral water purifier as provided in this specific embodiment and taking the device end of the mineral water purifier as the execution body, a control method for the mineral water purifier can be provided. Figure 5 The control method of the mineral water purifier provided in this application is a schematic flow chart of the process of emptying the water in the mineralized filter material. It should be noted that if there is substantially the same result, this embodiment is not based on Figure 5 The process sequence shown is limited. Figure 5 As shown, the control method of the mineral water purifier may include:

[0066] S101: receiving first water quality detection data sent by the first water quality detection component 51.

[0067] S102: receiving the third water quality detection data sent by the third water quality detection component 53.

[0068] S103: Determine whether the third water quality detection data and / or the first water quality detection data are qualified.

[0069] The third water quality detection data and / or the first water quality detection data may include mineral content. Judging whether the third water quality detection data and / or the first water quality detection data are qualified may include judging whether the mineral content therein is greater than a preset threshold value. For example, when the mineral content of the third water quality detection data and / or the first water quality detection data is greater than a preset threshold value, it indicates that the third water quality detection data and / or the first water quality detection data are unqualified.

[0070] S700: In response to at least one of the third water quality detection data and the first water quality detection data being unqualified, close the first control valve 41 and the second control valve 42, control the third control valve 43 to connect to the return water path 34, open the air valve and start the pump body 6.

[0071] When at least one of the third water quality test data and the first water quality test data is unqualified, since the rear-inserted water channel 32 downstream of the second control valve 42 is directly connected to the mineralized filter material 1, the water outlet channel 33 upstream of the first control valve 41 is also directly connected to the mineralized filter material 1, it means that the mineral content of the water in at least the rear-inserted water channel 32 downstream of the second control valve 42, the mineralized filter material 1, and the water outlet channel 33 upstream of the first control valve 41 is greater than the preset threshold.

[0072] At this time, the first control valve 41 and the second control valve 42 can be closed to isolate the post-insertion waterway 32 upstream of the second control valve 42 and the outlet waterway 33 downstream of the first control valve 41 from the mineralized filter material 1, and then the water body with a mineral content greater than a preset threshold value can be discharged into the return waterway 34 by starting the pump body 6, and the gas can enter the post-insertion waterway 32 downstream of the second control valve 42, the mineralized filter material 1, and the outlet waterway 33 upstream of the first control valve 41 through the air valve, so as to isolate the mineralized filter material 1 from the water body and stop the mineralized filter material 1 from dissolving minerals into the water body, thereby maintaining the service life of the mineralized filter material 1 while reducing the excessively high mineral content of the water outlet from the outlet waterway 33.

[0073] Optionally, the water system for the mineral water purifier may further include a communication component connected to the controller. The communication component can be used to receive a control message sent by a user and transmit the control message to the controller so that the controller can perform a corresponding operation according to the control message.

By setting the flow meter, the flow rate of the water flowing through the water system for the mineral water purifier can be monitored. Then, the timing of flushing the mineralized filter material 1 can be determined according to the flow rate, for example, the mineralized filter material 1 is flushed once every specified value of water flow. In addition, the service life of the mineralized filter material 1 can also be determined according to the flow rate.

[0076] Optionally, the water system for the mineral water purifier may also include a timer, and the timer signal is connected to the controller, which can monitor the use time of the water system for the mineral water purifier. Then, the timing of flushing the mineralized filter material 1 can be determined according to the use time, for example, the mineralized filter material 1 is flushed once every specified soaking time. And the service life of the mineralized filter material 1 can be determined according to the flow rate.

[0077] Optionally, the water system for the mineral water purifier may further include an inlet valve 44, which is connected to the front inlet waterway 31 and is used to control the opening or closing of the front inlet waterway 31.

[0079] To solve the above technical problems, the specific embodiments of the present application can also provide a mineral water purifier, including a water outlet component and a water system for a mineral water purifier as described in any of the above specific embodiments. The water outlet component can be used to discharge water to the outside, and the water outlet component can be connected to the water outlet 33 of the water system for a mineral water purifier.

[0080] In the structure provided in this specific embodiment, by providing a first water quality detection component 51, a first control valve 41 and a return water path 34, the first water quality detection component 51 can be used to detect the mineral content of the water in the mineralized filter material 1. When it is detected that the mineral content is too high, the first control valve 41 can be closed to stop the water from being discharged to the outside through the water outlet path 33. The water subsequently input into the mineralized filter material 1 can be used to replace the water with excessively high mineral content in the mineralized filter material 1, so that the water with excessively high mineral content can flow into the water purification device 2 through the return water path 34, and be purified again by the water purification device 2 to remove the minerals with excessively high content therein, thereby effectively solving the problem of excessively high mineral content in the water output from the water outlet path 33.
