Detailed Implementation
[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0041] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.
[0042] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.
[0043] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.
[0044] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a water system provided in an embodiment of the present invention. The water system may include: an inlet k1, a pure water path 11, a pure water branch path 12, a mineralized water path 13, a regulating water path 14, and a water outlet faucet 15. The inlet k1 can be connected to a water supply source, which can be tap water.
[0045] The inlet of the pure water circuit 11 is connected to the inlet k1, and the outlet of the pure water circuit 11 is connected to the inlet of the mineralized water circuit 13 and the inlet of the pure water branch circuit 12. The outlets of the mineralized water circuit 13 and the pure water branch circuit 12 are both connected to the water tap 15. The mineralized water circuit 13 has a mineralized filter element 131.
[0046] The pure water circuit 11 can be used to purify water. Tap water entering the water system through the inlet k1 can be purified in the pure water circuit 11. The pure water circuit 11 can have a filter component to filter and treat the tap water entering through the inlet k1, thereby outputting pure water. The two ends of the pure water branch circuit 12 are connected to the pure water circuit 11 and the water outlet faucet 15, respectively. The pure water branch circuit 12 can transmit the pure water produced by the pure water circuit 11 to the water outlet faucet 15 for users to use.
[0047] The two ends of the mineralized water path 13 are connected to the pure water path 11 and the water outlet 15, respectively. When the pure water flowing out of the pure water path 11 flows through the mineralized water path 13, the mineralized filter element 131 in the mineralized water path 13 can mineralize the pure water, turning it into mineralized water containing mineral elements, and can transmit the mineralized water to the water outlet 15 for the user to use.
[0048] The inlet of the regulating water path 14 is connected to the pure water branch 12, and the outlet of the regulating water path 14 is connected to the outlet of the mineralization filter element 131. The regulating water path 14 includes a flow regulating mechanism 141 for regulating the flow rate within it. Both ends of the regulating water path 14 are connected to the outlets of the pure water branch 12 and the mineralization water path 13, respectively. The regulating water path 14 can deliver pure water to the mineralization water path 13, where it mixes with the mineralized water, diluting the high-concentration mineralized water and adjusting the mineral content of the mineralized water to regulate the concentration of the mineralized water produced in the mineralization water path 13. For example, the flow rate of the regulating water path 14 can be positively correlated with the output concentration of the mineralization water path 13; that is, the higher the flow rate of the regulating water path 14, the lower the concentration of the mineralized water output by the mineralization water path 13, and vice versa. The flow regulation mechanism 141 can also be used to close or open the water passage 14.
[0049] For example, the faucet 15 in this embodiment of the present invention can output at least the following four types of water:
[0050] Please refer to Figure 2 , Figure 2 yes Figure 1 The diagram shows the flow direction of purified water output from the water system. The black arrows in the diagram indicate the flow direction. In the first case, there is no concentration of purified water. In this case, the pure water circuit 11 and the pure water branch circuit 12 are open, while the mineralization circuit 13 and the regulating circuit 14 are closed. After the tap water is purified by the pure water circuit 11, it flows through the pure water branch circuit 12 to the water tap 15. At this time, the water flowing out of the water tap 15 is purified water without added minerals.
[0051] Please refer to Figure 3 , Figure 3 yes Figure 1 The diagram shows the flow direction of the water system outputting high-concentration mineralized water. In the second type of high-concentration mineralized water, the pure water circuit 11 and the mineralized water circuit 13 are open, while the pure water branch circuit 12 and the regulating water circuit 14 are closed. After the tap water is purified by the pure water circuit 11, it is then mineralized by the mineralized water circuit 13 to generate high-concentration mineralized water, which then flows to the water tap 15. At this time, the water flowing out of the water tap 15 is high-concentration mineralized water with added minerals.
[0052] Please refer to Figure 4 , Figure 4 yes Figure 1The diagram shows the flow direction of diluted mineralized water output by the water system. In the third type of medium-concentration mineralized water, the pure water path 11, mineralized water path 13, and regulating water path 14 are open, while the outlet of the pure water branch 12 is closed. Tap water is purified through the pure water path 11 and then mineralized through the mineralized water path 13 to generate high-concentration mineralized water. At the same time, the pure water generated by the pure water branch 12 can also flow into the mineralized water path 13 through the pure water branch 12 and the regulating water path 14 (the flow rate in the regulating water path 14 is the first flow rate), and mix with the high-concentration mineralized water in the mineralized water path 13 before flowing to the water tap 15. At this time, the water flowing out of the water tap 15 is medium-concentration mineralized water without containing medium concentrations of minerals.
[0053] The fourth type of low-concentration mineralized water: In this case, the pure water circuit 11, the mineralized water circuit 13, and the regulating water circuit 14 are in the open state, and the outlet of the pure water branch circuit 12 is in the closed state. After the tap water is purified by the pure water circuit 11, it is then mineralized by the mineralized water circuit 13 to generate high-concentration mineralized water. At the same time, the pure water generated by the pure water branch circuit 12 can also flow into the mineralized water circuit 13 through the pure water branch circuit 12 and the regulating water circuit 14 (the flow rate in the regulating water circuit 14 is the second flow rate, which is greater than the first flow rate), and mix with the high-concentration mineralized water in the mineralized water circuit 13 before flowing to the water tap 15. At this time, the water flowing out of the water tap 15 is low-concentration mineralized water without medium concentration of minerals.
[0054] In the water system of this embodiment, a dedicated regulating water path 14 is set between the pure water branch 12 and the mineralized water path 13 to dilute the mineralized water by recirculating pure water, thereby regulating the concentration of the mineralized water. This allows for linear and precise dilution of high-concentration mineralized water to the target concentration. The single control variable in the regulation process simplifies the adjustment method. This achieves a mineral concentration regulation method with higher control precision and better stability, ensuring consistent water quality and taste when the user selects the same mineralized water concentration setting, thus improving the user experience.
[0055] Furthermore, under this regulation method, the concentration adjustment of the mineralized water is accomplished by the dilution process at the rear end of the mineralization water path 13, which has minimal impact on the mineralization process of the mineralization filter element 131 itself. The changes in liquid flow rate and inlet conditions in the mineralization water path 13 are minimal, resulting in a relatively stable concentration of minerals precipitated from the mineralization filter element 131, thus minimizing variations in the outlet concentration of the mineralization filter element 131 within the mineralization water path 13. This allows the mineralization filter element 131 to operate under relatively stable working conditions, which is beneficial for maintaining the consistency of its performance.
[0056] Furthermore, in the water system of this utility model embodiment, the concentration of mineralized water can be adjusted by a flow regulating mechanism 141, which can simplify the water system, reduce the probability of water system failure, and improve the overall reliability of the water system.
[0057] In summary, this utility model embodiment provides a water system including an inlet k1, a pure water path 11, a pure water branch path 12, a mineralized water path 13, a regulating water path 14, and a faucet 15. The pure water path 11 is connected to the inlet k1. Both ends of the mineralized water path 13 and the pure water branch path 12 are connected to the pure water path 11 and the faucet 15, respectively. The inlet end of the regulating water path 14 is connected to the pure water branch path 12, and the outlet end of the regulating water path 14 is connected to the outlet end of the mineralized filter element 131. The regulating water path 14 also includes a flow regulating mechanism 141. By setting a dedicated regulating water path 14 between the pure water branch path 12 and the mineralized water path 13, the concentration of the mineralized water is adjusted by diluting the mineralized water with pure water. This achieves a mineral concentration adjustment method with higher control precision and better stability, thus improving the user experience. Furthermore, this adjustment method allows the mineralizing filter element 131 to operate under relatively stable working conditions, which helps maintain the performance consistency of the mineralizing filter element 131. In addition, the concentration of mineralized water can be adjusted through a single flow regulating mechanism 141, which simplifies the water system.
[0058] Please refer to Figure 1 and Figure 4 In one optional embodiment, the regulating water path 14 may include a first pipeline, a flow regulating mechanism 141, and a first check valve 142; the inlet end of the first pipeline is connected to the pure water branch 12, and the outlet end of the first pipeline is connected to the mineralized water path 13 and is located between the mineralized filter element 131 and the water faucet 15; the flow regulating mechanism 141 and the first check valve 142 are installed sequentially on the first pipeline along the water flow direction.
[0059] The flow regulating mechanism 141 can control the flow of fluid in the first pipeline. That is, when the flow regulating mechanism 141 is open, fluid can pass through the flow regulating mechanism 141 and the first pipeline; when the flow regulating mechanism 141 is closed, the fluid in the first pipeline will be blocked by the flow regulating mechanism 141 and cannot pass through it. The flow regulating mechanism 141 may include valves, pumps, etc. The first one-way valve 142 can prevent mineralized water from flowing back to the pure water branch 12.
[0060] In one optional embodiment, the faucet 15 has a mineralized water switch 151 and a pure water switch 152, and the flow regulating mechanism 141 includes a proportional solenoid valve; the mineralized water switch 151 is installed at one end of the mineralized water path 13 for opening or closing the mineralized water path 13, and the pure water switch 152 is installed at one end of the pure water branch path 12 for opening or closing the pure water branch path 12; the mineralized water switch 151 has an adjustment range, and the mineralized water switch 151 is electrically connected to the proportional solenoid valve.
[0061] By linking the mineralized water switch 151 with the proportional solenoid valve, the concentration range of the mineralized water after mixing the mineralized water circuit 13 and the regulating water circuit 14 can be adjusted in steps or steplessly.
[0062] For example, the purified water filtered by the mineralization filter 131 first becomes high-concentration mineralized water. Users can adjust their needs through the gear on the mineralized water faucet. After receiving the signal from the mineralized water switch 151, the proportional regulating valve opens proportionally, so that the purified water in the first pipeline is mixed with the high-concentration mineralized water through the flow regulating mechanism 141 and the first one-way valve 142, thereby diluting and adjusting the mineral content, and realizing the output of mineralized water at different gears.
[0063] In one optional embodiment, the mineralized water path 13 may include a second pipe and a mineralized filter element 131. The inlet end of the second pipe is connected to the outlet end of the pure water path 11, and the outlet end of the second pipe is connected to the faucet 15. The mineralized filter element 131 is installed on the second pipe. The pure water branch path 12 includes a third pipe. The inlet end of the third pipe is connected to the outlet end of the pure water path 11, and the outlet end of the third pipe is connected to the faucet 15.
[0064] The pure water branch 12 may also include a flow meter 121, which is used to detect the outflow rate of pure water, thereby determining whether the filter components in the pure water circuit 11 are in good condition.
[0065] The mineralized filter element 131 can be filled with a preset amount of naturally selected mineral material to release essential mineral elements into the water, such as magnesium (Mg), calcium (Ca), potassium (K), strontium (Sr), and sodium (Na).
[0066] In one optional embodiment, the pure water circuit 11 may include a fourth pipeline, a first solenoid valve 111, a composite filter element 112, a booster pump 113, a reverse osmosis membrane filter element 114 (RO filter element), and a second check valve 115; the inlet end of the fourth pipeline is connected to the inlet port k1, and the outlet end of the fourth pipeline is connected to the inlet end of the second pipeline and the inlet end of the third pipeline, respectively; the first solenoid valve 111, the composite filter element 112, the booster pump 113, the reverse osmosis membrane filter element 114, and the second check valve 115 are installed sequentially on the fourth pipeline along the water flow direction.
[0067] Composite filter element 112 can be used to remove large particulate impurities in water, such as silt, rust, and suspended solids, and adsorb residual chlorine, odors, color, and some organic matter and chemical pollutants in the water. Reverse osmosis membrane filter element 114 is mainly used to filter out smaller particles, bacteria, viruses, chemicals, and minerals.
[0068] In one exemplary embodiment, when the regulating water circuit 14 is opened, the water supply of the booster pump 113 can be adjusted according to the opening degree of the proportional solenoid valve 141. For example, if the opening degree of the proportional solenoid valve 141 increases, the water supply of the booster pump 113 can be increased accordingly, thereby stabilizing the water flow in the mineralization water circuit 13, and thus enabling the mineralization filter element 131 to work in a relatively stable water flow state.
[0069] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In an optional embodiment, the water system may further include a high-pressure switch s1, which is installed on the second, third, or fourth pipeline and located between the second check valve 115 and the water tap 15. The high-pressure switch s1 is electrically connected to the first solenoid valve 111 and the booster pump 113. The water system may also include a wastewater path 16, which includes a sixth pipeline and a third solenoid valve 161 installed on the sixth pipeline. Thus, the combination of the second check valve 115 and the high-pressure switch s1, along with the dual water tap 15 having a mineralized water switch 151 and a pure water switch 152, enables the water system to dispense both pure water and mineralized water, and also simplifies the structure of the water system. For example, the high-pressure switch s1 may be installed at the outlet end of the fourth pipeline.
[0070] In one exemplary embodiment, when the user opens the mineral water switch 151 of the water faucet 15, the high-pressure switch s1 detects a decrease in water pressure in the pipeline between the second one-way valve 115 and the water faucet 15, such as a decrease to a preset opening threshold pressure. Then, the first solenoid valve 111 and the booster pump 113 start working, and the incoming water passes sequentially through the first solenoid valve 111, the composite filter element 112, the booster pump 113, the reverse osmosis membrane filter element 114, the second one-way valve 115, and the mineral water filter element 131, finally exiting from the water faucet 15 as mineral water. The wastewater generated by the reverse osmosis membrane filter element 114 is discharged through the third solenoid valve 161. When the user closes the mineral water faucet, the first solenoid valve 111 and the booster pump 113 continue to work until the high-pressure switch s1 detects that the water pressure between the second one-way valve 115 and the water faucet 15 rises to a preset closing threshold pressure. Then, the first solenoid valve 111 and the booster pump 113 stop working, the entire machine stops, and the water faucet 15 stops discharging water.
[0071] In one exemplary embodiment, when the user opens the pure water switch 152 of the water tap 15, the high-pressure switch s1 detects that the water pressure in the pipeline between the second one-way valve 115 and the water tap 15 has dropped to a preset opening threshold pressure. Then, the first solenoid valve 111 and the booster pump 113 start working, and the incoming water passes sequentially through the first solenoid valve 111, the composite filter element 112, the booster pump 113, the reverse osmosis membrane filter element 114, the second one-way valve 115, and the flow meter 121, and finally pure water is discharged from the water tap 15. The wastewater generated by the reverse osmosis membrane filter element 114 is discharged by the third solenoid valve 161. When the user closes the mineral water tap, the first solenoid valve 111 and the booster pump 113 continue to work until the high-pressure switch s1 detects that the water pressure between the second one-way valve 115 and the water tap 15 has risen to a preset closing threshold pressure. Then, the first solenoid valve 111 and the booster pump 113 stop working, the whole machine stops, and the water tap 15 stops discharging water.
[0072] In one exemplary embodiment, when the user turns on the mineral water switch 151 of the faucet and selects the mineral water concentration as medium, the incoming water sequentially passes through the first solenoid valve 111, the composite filter element 112, the booster pump 113, the reverse osmosis membrane filter element 114, the second one-way valve 115, and the mineral water filter element 131 to the outlet of the mineral water path 13. The pure water filtered by the mineral water filter element 131 becomes high-concentration mineral water. At the same time, according to the user's mineral concentration selection, the proportional solenoid valve opens at a certain ratio. The pure water output from the reverse osmosis membrane filter element 114 sequentially passes through the second one-way valve 115, the proportional solenoid valve, and the first one-way valve 142, and mixes with the mineral water at the outlet of the mineral water path 13 to dilute the high-concentration mineral water, adjust the mineral content of the mineral water, and finally, medium-concentration mineral water is discharged from the faucet 15.
[0073] In one alternative implementation, please refer to Figure 1 and Figure 5 , Figure 5 yes Figure 1The diagram shows the water flow direction of the water system in backwash mode. The water system may also include a backwash water path 17, whose inlet is connected to the outlet of the mineralizing filter element 131 and the inlet of the booster pump 113. The backwash water path 17 may include a fifth pipeline, a second solenoid valve 171, and a third check valve 172. The inlet of the fifth pipeline is connected to the second pipeline and is located between the mineralizing filter element 131 and the water outlet faucet 15. The outlet of the fifth pipeline is connected to the fourth pipeline and is located between the composite filter element 112 and the booster pump 113. The second solenoid valve 171 and the third check valve 172 are installed sequentially on the fifth pipeline along the water flow direction. When a user does not collect water for a long time, the mineralization filter 131 will continuously precipitate minerals from the water after being soaked for a long time. This will cause the concentration of mineralized water to be too high when the user collects the water next time, making it impossible to drink normally. Therefore, the concentration of mineralized water in the mineralization filter 131 can be adjusted through the backwash water circuit 17 to avoid the phenomenon of excessively high concentration of mineralized water flowing out of the water circuit system.
[0074] In an optional embodiment, the water system may further include a first water quality analyzer c1, a second water quality analyzer c2, and a backwash switch; the first water quality analyzer c1 is installed at the inlet end of the mineralization filter element 131, and the second water quality analyzer c2 is installed at the outlet end of the mineralization filter element 131; the backwash switch is electrically connected to the first water quality analyzer c1 (TDS), the second water quality analyzer c2, the first solenoid valve 111, the booster pump 113, and the second solenoid valve 171, and the backwash switch is configured to: when the difference between the detected value of the first water quality analyzer c1 and the detected value of the second water quality analyzer c2 reaches a preset difference, open or close the first solenoid valve 111, the booster pump 113, and the second solenoid valve 171.
[0075] By installing two water quality detectors between the inlet and outlet of the mineralization filter element 131, when the difference between the two water quality detectors exceeds a preset difference, the first solenoid valve 111, the booster pump 113, and the second solenoid valve 171 are opened. The incoming water flows back to the booster pump 113 in sequence through the first solenoid valve 111, the composite filter element 112, the booster pump 113, the reverse osmosis membrane filter element 114, the second one-way valve 115, the mineralization filter element 131, the second solenoid valve 171, and the third one-way valve 172, so that the mineral content in the mineralized water in the mineralization filter element 131 does not exceed the threshold. The wastewater generated by the reverse osmosis membrane filter element 114 is discharged through the third solenoid valve 161.
[0076] In one exemplary embodiment, the water system may further include a third water quality analyzer c3 and a control component, the water quality analyzer being used to monitor the filtration function of the composite filter element 112. The control component may be electrically connected to multiple solenoid valves, pumps, switches, and the water quality analyzer in the water system to control the stable operation of the water system.
