[0050] Figure 2 A structure diagram of a waterway plate according to an embodiment of the present application is schematically shown.

[0051] According to an embodiment of the present application, as shown in Figure 2 The waterway plate 10 is provided with a first water inlet interface and a first water outlet interface corresponding to the water inlet end and the water outlet end of the filtering assembly 20 respectively, and a second water inlet interface and a second water outlet interface corresponding to the water inlet end and the water outlet end of the mineralization assembly 30 respectively.

[0053] In some embodiments, the waterway plate 10 can be provided with a plurality of interfaces, and the filtering assembly 20 and the mineralization assembly 30 can be directly plugged into the waterway plate 10 through the interfaces.

[0054] Specifically, the waterway plate 10 has a first face and a second face opposite to the first face. The first face of the waterway plate 10 can be provided with a first water inlet interface and a first water outlet interface corresponding to the water inlet end and the water outlet end of the filtering assembly 20 respectively, to realize the connection between the waterway plate 10 and the filtering assembly 20; the first face of the waterway plate 10 can also be provided with a second water inlet interface and a second water outlet interface corresponding to the water inlet end and the water outlet end of the mineralization assembly 30 respectively, to realize the connection between the waterway plate 10 and the mineralization assembly 30.

[0055] According to the embodiment of the utility model, water inlet channel is also formed in waterway board 10, water inlet 11 of water inlet channel is arranged on the surface of waterway board 10 to connect raw water pipeline.

[0056] Specifically, waterway board 10 also has third face and fourth face adjacent to first face and second face, and water inlet 11, first drain outlet 12 and second drain outlet 13 can be arranged on the third face of waterway board.

[0057] In some embodiments, first drain channel, second drain channel and water inlet channel can be integrally injection molded with the main body of waterway board 10 to reduce the risk of water leakage.

[0058] In such an implementation, the water inlet pipeline and the water outlet pipeline can be integrated by waterway board 10, which simplifies the structure of the water purification device, makes the device more compact, and also facilitates users to replace the filter assembly 20 and the mineralization assembly 30.

[0059] According to another embodiment of the utility model, the water guide assembly further includes a first drain pipe and a second drain pipe. The first drain pipe is arranged between the drain end of the filter assembly 20 and the external water environment, and the first drain channel is formed in the first drain pipe. The second drain pipe is arranged between the drain end of the mineralization assembly 30 and the external water environment, and the second drain channel is formed in the second drain pipe.

[0060] In some embodiments, the external water environment can be a connection pipeline machine or a heating device; in some embodiments, the external water environment can also be a faucet, which directly supplies users for use.

[0061] In some embodiments, the water guide assembly can further include a water inlet pipe, the water inlet channel is formed in the water inlet pipe, the water inlet end of the water inlet channel is connected with the external raw water pipeline, and the drain end of the water inlet channel is connected with the water inlet end of the filter assembly 20.

[0062] In some embodiments, the water inlet pipe, the first drain pipe and the second drain pipe can be made of materials including but not limited to PE pipe (polyethylene pipe), PP pipe (polypropylene pipe) and the like.

[0063] According to the embodiment of the utility model, as shown in Figure 2 The water purification device further includes a first regulating valve 41, a second regulating valve 42 and a controller. The first regulating valve 41 is arranged in the first drain channel. The second regulating valve 42 is arranged in the second drain channel. The controller is configured to control the opening degree of the first regulating valve 41 and the second regulating valve 42.

[0064] In some embodiments, the first regulating valve 41 and the second regulating valve 42 can be solenoid valves, and the first regulating valve 41 and the second regulating valve 42 are in communication connection with the controller. In response to the operation of the user, the controller controls the opening degree of the solenoid valve according to the received operation signal to open or close the first drainage channel or the second drainage channel, so as to switch the water of the first water quality or the water of the second water quality.

[0065] In some embodiments, the first regulating valve 41 and the second regulating valve 42 can also be water pump assemblies containing one-way valves. The first water pump and the second water pump can be respectively arranged in the first drainage channel and the second drainage channel, and the one-way valves are respectively arranged at the water outlets of the first water pump and the second water pump, so as to ensure that the water flow can only flow in the water outlet direction of the water pump. By accurately controlling the water pump assembly by the controller, the opening and closing of the water flow in the first drainage channel and the second drainage channel can be realized. For example, when the water of the first water quality is needed to be output, the controller can open the first water pump assembly and close the second water pump assembly; conversely, when the water of the second water quality is needed to be output, the second water pump assembly is opened and the first water pump assembly is closed.

[0066] In such an embodiment, by arranging the first regulating valve 41 and the second regulating valve 42 on the first drainage channel and the second drainage channel respectively, and combining the intelligent control of the controller, the water purification device can output water of different water qualities according to the needs of the user, and the flexibility of use of the water purification device is improved.

[0067] According to the embodiments of the present application, the water purification device further comprises a first sensor 51. The first sensor 51 is arranged in the second drainage channel, and the first sensor 51 is used for detecting the first total dissolved solid amount of the water of the second water quality. The controller is further configured to adjust the opening degree of the second regulating valve 42 based on the first total dissolved solid amount.

[0068] The first sensor 51 is used for detecting the first total dissolved solid amount (Total Dissolved Solids, referred to as TDS) of the water of the second water quality after the mineralization treatment of the mineralization assembly 30. According to the TDS value N1 in the water of the second water quality, it can be judged whether the water of the second water quality is mineralized enough.

[0069] In some embodiments, the first sensor 51 is connected with the controller through an electric wire or a data line, and can transmit the detected TDS value N1 to the controller in real time.

[0070] In some embodiments, a threshold value N0 of TDS can be preset. When the first sensor 51 detects that the TDS value N1 of the second quality water is lower than the threshold value N0, or continuously lower than the threshold value N0 within a preset time period, for example, 0.2 seconds to 3 seconds, it indicates that the mineralization degree of the second quality water is insufficient. The controller sends a signal to the second regulating valve 42 to reduce the opening of the second regulating valve 42 or temporarily close the second regulating valve 42 for a period of time, so as to increase the residence time of the water flow in the mineralization assembly 30, thereby increasing the mineralization ions in the second quality water.

[0071] When the first sensor 51 detects that the TDS value N1 of the second quality water is higher than the threshold value N0, it indicates that the mineralization degree of the second quality water is sufficient. The controller can send a signal to the second regulating valve 42 to restore the opening of the second regulating valve 42, thereby increasing the flow of the second quality water.

[0072] According to an embodiment of the present application, the water purification device further comprises a second sensor 52. The second sensor 52 is arranged in the first water outlet channel, and the second sensor 52 is used to detect the second total dissolved solid amount of the first quality water. The controller is further configured to adjust the opening of the second regulating valve 42 based on the first total dissolved solid amount and the second total dissolved solid amount.

[0073] In some embodiments, the second sensor 52 is connected to the controller through an electric wire or a data line, and can transmit the detected TDS value N2 to the controller in real time.

[0074] In some embodiments, the second sensor 52 is arranged in the first water outlet channel to detect the TDS value N2 of the first quality water before entering the mineralization assembly 30, and the first sensor 51 is arranged in the second water outlet channel to detect the TDS value N1 of the second quality water after being treated by the mineralization assembly 30. According to the values of N1 and N2, the controller can adjust the second regulating valve 42 based on a preset logic.

[0075] According to an embodiment of the present application, the controller is configured to reduce the opening of the second regulating valve 42, or close the second regulating valve 42, when the first total dissolved solid amount continuously decreases by a preset multiple of the second total dissolved solid amount within a preset time period.

[0076] For example, when N1 is less than 1.1 times of N2 for a preset time period, for example, 0.2 seconds to 3 seconds, it indicates that the mineralization degree of the second water is insufficient, and the controller can send a signal to the second regulating valve 42 to reduce the opening of the second regulating valve 42 or temporarily close the second regulating valve 42 for a period of time to increase the residence time of the water flow in the mineralization assembly 30, so as to increase the mineralization ions in the second water. When N1 is higher than 1.1 times of N2, it indicates that the mineralization degree of the second water is sufficient, and the controller can send a signal to the second regulating valve 42 to restore the opening of the second regulating valve 42 to increase the flow of the second water.

[0077] The adjustment of the second regulating valve according to N1 and 1.1 times of N2 in the above embodiment is only illustrative, and the present application is not limited thereto. Other judgment logics can also be used, such as that N1 is less than N2 plus a preset value for a preset time period.

[0078] In such an embodiment, by detecting the TDS values before and after entering the mineralization assembly 30 through the second sensor 52 and the first sensor 51 respectively, the controller can intelligently adjust the opening of the second regulating valve 42 according to the real-time changes of the water quality in the two water outlet pipelines, to ensure that the second water meets the preset standards or requirements. At the same time, according to the TDS values before and after entering the mineralization assembly 30, potential problems of the mineralization assembly 30 can be found in time, such as whether the mineralization assembly 30 is invalid or not.

[0079] In some embodiments, the water drainage assembly further comprises a third drainage passage connected to the waste water end of the filtration assembly 20 to drain the waste water generated after filtration.

[0080] In some embodiments, a third drainage port 14 for outputting waste water can be provided on the waterway plate 10, and the third drainage passage is provided in the waterway plate 10 and communicates with the third drainage port. The third drainage passage can further be provided with a third regulating valve 43. The third regulating valve 43 is used to control the opening or closing of the third drainage passage to output the waste water generated after filtration by the filtration assembly 20.

[0081] In some embodiments, the water drainage assembly further comprises a third drainage pipe connected to the waste water end of the filtration assembly 20 to drain the waste water generated after filtration.

[0082] In some embodiments, a fourth drain (not shown in the figures) can be provided on the waterway plate 10, and a fourth drain channel connecting the first filter 21 and the fourth drain and a fourth regulating valve can also be provided on the waterway plate 10. The fourth regulating valve is used to control the opening or closing of the third water outlet pipe, and is used to output water of the third water quality generated by the first filter 21. For example, the first filter 21 can be provided with only a PP cotton filter element or an activated carbon filter element, and can be used to preliminarily filter raw water to remove large-particle impurities and part of harmful substances, so as to obtain water of the third water quality. The water of the third water quality can be used as domestic water, and can be used for cleaning articles and the like.

[0083] In some embodiments, in the case where the fourth drain channel and the fourth drain are provided, the water purification device further comprises a third sensor. The third sensor is arranged on the fourth drain channel to detect the third total dissolved solid amount of the water of the third water quality. The running condition of the filter, the filtering efficiency of the filtering material and the like can be judged according to the TDS value N3 measured by the third sensor and the TDS value N2 measured by the first sensor 51.

[0084] According to the embodiments of the present application, the filtering assembly 20 comprises at least one filter in series.

[0085] In some embodiments, the filtering assembly 20 can comprise 1, 2, 3 or 4 filters or the like. The number of filters is not limited in the present application. Different filter elements can be arranged in each filter, so that each filter has different filtering functions or filters different types of impurities.

[0086] According to the types of water quality impurities, the plurality of filters can be roughly divided into three filtering systems, and each filtering system comprises at least one filter. The first filtering system is mainly used to filter and treat particles, sand, residual chlorine in tap water, chemicals, different colors, odors and the like with a diameter greater than 1-5 microns. The second filtering system is mainly used to remove bacteria, heavy metals, salt, harmful minerals and other dissolved substances, chemical agents and the like in water. The third filtering system is mainly used to adjust the taste of pure water, inhibit the reproduction of bacteria and keep the freshness of pure water.

[0087] In such an embodiment, different numbers, different types or different filtering accuracies of filters can be selected to be connected in series according to different water quality requirements and use scenarios, so as to meet specific filtering requirements.

[0088] In some embodiments, filters with different functions can also be integrated into one filter to save space of the water purification device.

[0089] According to the embodiments of the present application, as shown in Figure 2 The filtering assembly 20 comprises the first filter 21 and the second filter 22.

[0090] In some embodiments, the first filter 21 can be a filter with only one type of filter element, which can be used to preliminarily filter raw water, remove large particle impurities and part of harmful substances, and obtain third-quality water, which can be used as domestic water, such as cleaning water, etc. The second filter 22 can be a filter with multiple types of filter elements integrated, which can be connected in series with the first filter 21 to further finely filter the third-quality water, remove smaller particles, residual chemicals, heavy metals, salts, harmful minerals, and other dissolved substances, and improve the taste and odor of the water, etc., to obtain first-quality water, which can be pure water and can be used for drinking, cooking, etc.

[0091] In some embodiments, the first filter 21 can be a filter with multiple types of filter elements integrated to remove most of the particles and harmful substances. The second filter 22 can be a filter with a specific type of filter element to remove specific pollutants, such as heavy metals, or to improve the taste, etc.

[0092] In some embodiments, the first filter 21 and the second filter 22 can both be filters with multiple types of filter elements integrated.

[0093] According to an embodiment of the present application, the first filter 21 is provided with at least one of a polypropylene melt-blown filter element and an activated carbon filter element, and the second filter 22 is provided with a composite filter element comprising a reverse osmosis membrane.

[0094] In some embodiments, the first filter 21 is mainly used to remove large particle impurities in raw water, and the second filter 22 is used to further finely filter the raw water, including removing small particle impurities, bacteria, and some soluble substances, etc.

[0095] In some embodiments, the composite filter element of the second filter 22 can be a combination of at least one of a reverse osmosis membrane and PP cotton or activated carbon.

[0096] In some embodiments, the reverse osmosis membrane in the composite filter element of the second filter 22 can also be replaced by an ultrafiltration membrane or a nanofiltration membrane.

[0097] According to an embodiment of the present application, the first filter 21 is provided with a composite filter element comprising a reverse osmosis membrane, and the second filter 22 is provided with at least one of a polypropylene melt-blown filter element and an activated carbon filter element.

[0098] In some embodiments, the first filter 21 is mainly used to remove most of the impurities, bacteria, and some soluble substances, etc. in raw water. The second filter 22 is mainly used to adjust the taste of pure water, inhibit the reproduction of bacteria, and maintain the freshness of pure water, etc.

[0099] In some embodiments, the composite filter element of the first filter 21 can be a reverse osmosis membrane combined with at least one of PP cotton and activated carbon.

[0100] In some embodiments, the reverse osmosis membrane in the composite filter element of the first filter 21 can also be replaced by an ultrafiltration membrane or a nanofiltration membrane.

[0101] In some embodiments, the filter element in the second filter 22 can also be a filter element for adsorbing heavy metal particles.

[0102] In such an implementation, by arranging the first filter 21 and the second filter 22 and arranging the composite filter element in the first filter 21 or the second filter 22, the space of the water purification device can be effectively saved.

[0103] According to an embodiment of the present application, the mineralization assembly 30 comprises at least one layer of mineralization filter element, and the mineralization filter element is used to release mineral ions to the first water flowing into the mineralization assembly 30.

[0104] In some embodiments, the mineralization filter element can comprise trace elements beneficial to human body such as silicon, iron, calcium, magnesium, zinc and strontium.

[0105] In some embodiments, the mineralization filter element can be composed of multiple layers of mineralization layers, each layer of mineralization layer can contain different mineral elements, and the mineral material can exist in the form of particles, powder or other forms and be stacked in the filter element according to a certain arrangement.

[0106] In some embodiments, the mineralization assembly 30 can be connected in series with the second filter 22 through the first branch waterway, and the raw water is filtered through the first filter 21 and the second filter 22, and then flows into the mineralization assembly 30 from the first branch waterway, and the trace elements beneficial to human body such as silicon, iron, calcium, magnesium, zinc and strontium are supplemented into the water through the mineralization assembly 30 to obtain the second water.

[0107] In such an implementation, since the raw water is filtered through the first filter 21 and the second filter 22, most of the impurities and heavy metals in the raw water are removed, and at the same time, the mineral elements beneficial to human body in the water are inevitably removed, which are essential elements for human growth and development. Long-term use of pure water will cause mineral deficiency in human body and cause a series of health problems. By arranging the mineralization filter element in the mineralization assembly 30, part of the mineral ions in the mineral material will be gradually released into the water when the water flows through the filter element, so as to increase the mineral content in the water and improve the water quality.

[0114] Figure 4 A waterway connection diagram of another water purification device according to an embodiment of the present application is schematically shown.

[0115] In the present embodiment, as shown in Figure 4 The water purification device is provided with a third filter 23 in addition to the first filter 21 and the second filter 22. The first filter 21, the second filter 22 and the third filter 23 can be filters provided with only one filter core. For example, the first filter is provided with one of a PP cotton filter core or an activated carbon filter core, the second filter is provided with a reverse osmosis membrane filter core, and the third filter is provided with an activated carbon filter core.

[0116] The first filter 21, the second filter 22, the third filter 23, and the mineralization component 30 are connected in series. The drain end of the third filter 23 is connected to a first drain channel, and the drain end of the mineralization component 30 is connected to a second drain channel. The first drain channel is equipped with a second sensor 52 and a first regulating valve 41; the second drain channel is equipped with a first sensor 51 and a second regulating valve 42. The first and second drain channels can be connected to an external faucet. By controlling the opening and closing of the first regulating valve 41 and the second regulating valve 42, water of corresponding qualities can be output respectively. Simultaneously, the opening degree of the second regulating valve 42 can be controlled based on the TDS value monitored by the first sensor 41 and the second sensor 42 to control the flow rate of the second water quality. Therefore, users can select different water qualities to be output as needed, improving the utilization rate and flexibility of each component of the water purification equipment.

[0117] Figure 5 A flowchart illustrating the operation of a water purification device according to an embodiment of the present invention is shown.

[0118] like Figure 5 As shown, this water purification device can determine its corresponding operating mode based on user operation. When the user operates in the first operating mode, the first regulating valve 41 is opened, outputting water of the first water quality. Simultaneously, the second sensor 52 detects the TDS value N2 of the first water quality and outputs the TDS value N2 to the controller and display screen. When the user operates in the second operating mode, the second regulating valve 42 is opened, outputting water of the first water quality. The first sensor 51 detects the TDS value N1 of the second water quality and outputs the TDS value N1 to the controller and display screen. The controller determines whether the preset value N1 is greater than a preset value. The preset value can be a preset TDS threshold or a value determined based on N2, such as 1.1 times the value of N2. When N1 is continuously less than the preset value within a preset time period, the flow rate of the second valve is adjusted to increase the residence time of the second water quality in the mineralization component 30, thereby increasing the degree of mineralization. This continues until the TDS value N1 is greater than the preset value, and the TDS value N1 is output to the controller and display screen. In response to the user ending the operation, all regulating valves are closed.

[0119] The water purification equipment according to this utility model can output water of different qualities according to the user's needs, thus meeting the diverse needs of the user.
