The water flow balance of the single-channel desalination assembly 100 and the double-channel desalination assembly 200 is realized by detecting the water flow of the single-channel desalination assembly 100 and the double-channel desalination assembly 200, feedback-adjusting the operating frequency of the driving assembly 20 according to the detected first water flow of the single-channel desalination assembly 100 and the detected second water flow of the double-channel desalination assembly 200, and further changing the driving pressure provided by the driving assembly 20 to change the water flow of the single-channel desalination assembly 100 and the double-channel desalination assembly 200, thereby adjusting the water flow proportion of the single-channel desalination assembly 100 and the double-channel desalination assembly 200.
Also, the pure water is simultaneously purified by the single-channel desalination module 100 and the double-channel desalination module 200, and the amount of the pure water generated is large. Furthermore, the single-channel desalination module 100 may not discharge wastewater when performing purification treatment on water flowing therethrough. By using the single-channel desalination assembly for water purification, water entering the single-channel desalination assembly 100 can be discharged from the first water outlet 120 and purified, and no wastewater is generated in the process, thereby improving the utilization rate of water.
In some embodiments, as shown in fig. 1 and 2, the pipe system 300 further includes a third pipe 330 and a waterway switching device 340, wherein the waterway switching device 340 is connected to the first water outlet 110.
Illustratively, waterway switching device 340 includes a tangential valve or a plurality of two-way solenoid valve sets, such as three-way valves, etc.
In the process of purifying water by the single-channel desalination assembly 100, a positive voltage is applied to the single-channel desalination assembly 100, the waterway switching device 340 is tangentially connected to the second pipeline, the water flowing in through the first water inlet 110 is purified, and the treated water flows out to the second pipeline 320 through the first water outlet 120.

Exemplary, the physisorption desalination filter element may include at least one of a Capacitive Desalination (CDI) filter element, a Membrane Capacitive Desalination (MCDI) filter element.
Specifically, the capacitive desalination filter element, the membrane capacitive desalination filter element, the bipolar membrane electrodeionization filter element and the like can cause the directional migration of cations and anions when being powered on, so as to realize the purification treatment of water, and the filter elements can be called as electrically-driven single-channel desalination filter elements. The reverse osmosis membrane filter core can realize the purification treatment of water when exerting pressure, can be called pressure drive binary channels desalination filter core.
Specifically, as shown in fig. 3 and 4, a schematic diagram of a structure of a bipolar membrane electrodeionization filter cartridge 900 is shown.
As shown in fig. 3 and 4, the bipolar membrane electrodeionization filter cartridge 900 includes one or more pairs of electrodes 910, and at least one bipolar membrane 920 or a plurality of spaced-apart bipolar membranes 920 is disposed between at least one pair of electrodes 910. Wherein, bipolar membrane 920 includes cation exchange membrane 921 and anion exchange membrane 922, and cation exchange membrane 921 and anion exchange membrane 922 set up relatively, compound together. For example, the bipolar membrane 920 can be produced by a hot press molding method, a bonding molding method, a casting molding method, an anion and cation exchange radical method, an electrodeposition molding method, or the like. Specifically, there is no space between the cation exchange membrane 921 and the anion exchange membrane 922 on one bipolar membrane 920, for example, water does not pass between the cation exchange membrane 921 and the anion exchange membrane 922 on the same bipolar membrane 920 when flowing through the bipolar membrane electrodeionization filter cartridge 900.
As shown in fig. 3 and 4, the pair of electrodes 910 includes a first electrode 911 and a second electrode 912, wherein the first electrode 911 is disposed opposite to a cation exchange membrane 921 of the bipolar membrane 920 adjacent to the first electrode 911, and the second electrode 912 is disposed opposite to an anion exchange membrane 922 of the bipolar membrane 920 adjacent to the second electrode 912.
Fig. 3 is a schematic diagram showing the operation principle of the bipolar membrane electrodeionization filter element 900 in the process of purifying water. Here, the potential of the first electrode 911 is higher than that of the second electrode 912, that is, a voltage in a forward direction is applied between the first electrode 911 and the second electrode 912. At this time, anions such as chloride ions in the raw water to be purified move towards the first electrode 911, and replace OH < - > in the anion exchange membrane 922 in the direction of the first electrode 911, and the OH < - > enters the flow channel between the adjacent bipolar membranes 920; meanwhile, cations such as Na + in the raw water move towards the second electrode 912 to replace H + in the cation exchange membrane 921 in the direction of the second electrode 912, and the H + enters the flow channel; h + and OH-are subjected to neutralization reaction in the flow channel to generate water, so that the salt in the raw water is removed, and purified pure water flows out from the tail end of the flow channel.
As shown in fig. 4, when a voltage in the opposite direction is applied between the first electrode 911 and the second electrode 912, so that the potential of the first electrode 911 is lower than that of the second electrode 912, OH "and H + ions are generated on the surfaces of the cation exchange membrane 921 and the anion exchange membrane 922 of the bipolar membrane 920 under the action of an electric field, cations such as Na + inside the cation exchange membrane 921 are replaced by H + ions and move toward the first electrode 911 at a low potential, anions such as chloride ions in the anion exchange membrane 922 are replaced by OH" and move toward the second electrode 912 at a high potential, and the cations such as Na + and the anions such as chloride ions enter the flow channel and can be washed out by water flowing through the bipolar membrane electrodeionization filter 900. Therefore, when the power is off or reverse voltage is applied to the desalting filter cores such as the bipolar membrane electrodeionization filter core 900 and the like, cations such as Na < + >, anions such as chloride ions and the like adsorbed on the bipolar membrane 920 are released, so that salt substances in the desalting filter core can be washed out by water to realize regeneration; water carrying cations such as Na + and anions such as chloride ions can be called concentrated water.
Illustratively, as shown in fig. 5, the household water purifying apparatus may further include a power supply module 420, wherein the power supply module 420 is connected to the single channel desalination module 100 and applies a forward voltage or a reverse voltage to the single channel desalination module 100. For example, an electrically driven single-channel desalination filter element is connected to supply power to the electrically driven single-channel desalination filter element.
In some embodiments, the voltage at which the power supply assembly 420 supplies power to the electrically driven single-channel desalination cartridge can be adjusted, and the desalination rate of the electrically driven single-channel desalination cartridge changes as the voltage supplied by the power supply assembly 420 is adjusted.
Exemplarily, the running voltage of the electrically-driven single-channel desalination filter element adapted to the water quality can be set according to the difference of the water quality of the using region of the household water purifying device, so that the water purified by the electrically-driven single-channel desalination filter element can meet the requirement. For example, when the quality of the water supplied from the water supply pipe is hard, the power supply voltage of the power supply module 420 may be set high; when the water quality of the tap water pipe supply water is soft, the supply voltage of the power supply module 420 may be set low.
Illustratively, after the single-channel desalination assembly 100 has been in operation for a certain period of time, more salts are adsorbed during the water purification process, and the single-channel desalination assembly 100 needs to be regenerated.
In some embodiments, the third line 340 can be flushed by water flowing from the first water outlet 120 of the single channel desalination assembly 100 by de-energizing or applying a reverse voltage to the single channel desalination assembly 100 to enable the saline in the single channel desalination assembly 100.
In other embodiments, the single-channel desalination assembly 100 can be removably received within the interior of a domestic water purification device, such that the single-channel desalination assembly 100 can be removed from the domestic water purification device for flushing when desired, thereby allowing regeneration of the filter elements of the single-channel desalination assembly 100.
In some embodiments, as shown in fig. 5, the control module 410 is connected to the power module 420 and the waterway switching device 340, and the power module 420 is connected to the single-channel desalination module 100. The control component 410 may include, for example, a single chip microcomputer or the like.
Illustratively, the control component 410 may include input devices, which may include, for example, buttons, knobs, touch screens, microphones, and the like.
Illustratively, when the control module 410 detects a water output control operation through an input device, such as a user pressing a water output button, or sends out a voice including a water output command, the power supply module 420 is controlled to apply a forward voltage to the single channel desalination module 100 according to the detected water output control operation, and the water path switching device 340 is also controlled to be tangential to the second pipeline 320, so that purified water purified by the single channel desalination module 100 can be output to the second pipeline 320.
In some embodiments, when the control module 410 switches to the regeneration mode during a preset time period, such as a time period from 10 pm to half 10 pm, the control module 410 controls the power supply module 420 to cut off power to the single channel desalination module 100 or to apply a reverse voltage to the single channel desalination module 100, and controls the waterway switching device 340 to cut off the current direction to the third pipeline 330. Such that salt ions attached to the single-channel desalination assembly 100 enter the water and exit the single-channel desalination assembly 100 with the water.

The filter assembly 360 in the first line 310 is capable of purifying the water entering the single-channel desalination assembly 100 to a certain extent, for example, to remove the water that may contain particulate impurities, residual chlorine, etc., thereby reducing the workload and consumption of the single-channel desalination assembly 100 and prolonging the regeneration cycle and service life thereof. The filtering assembly 360 on the second pipe 320 can further improve the quality of the pure water output from the household water purifying apparatus.
In some embodiments, the outlet direction of the second pipe 320 may be further connected to a heating unit, for example, a heat exchanger. The heating unit may heat the water flowing out of the second pipe 320 to provide the user with hot water of a desired temperature.
For example, the water outlet direction of the second pipeline 320 is connected to a plurality of second pipelines, and at least one of the second pipelines is provided with a heating unit.
In some embodiments, as shown in FIGS. 1 and 2, a temperature sensing assembly 40 may also be disposed in the first conduit 310, the temperature sensing assembly 40 being configured to sense the temperature of the water flowing to the single-channel desalination assembly 100 and the dual-channel desalination assembly 200.

The water quality of the water at the corresponding position can be detected by the conductivity detection assembly 10. For example, the TDS value is a water quality test indicator specifically set for purified water, and represents the total soluble solids content of water. The TDS value can reflect the water quality to a certain degree, and generally, the lower the TDS value is, the less soluble salts such as heavy metal ions in the water are, and the purer the water quality is.
For example, the conductivity detection module 10 may be disposed on the first water outlet side of the single-channel desalination module 100 and the second water outlet side of the dual-channel desalination module 200, respectively, and the conductivity of the water from the single-channel desalination module 100 and the conductivity of the water from the dual-channel desalination module 200 may be detected by the conductivity detection module 10, so as to determine whether the water purification effect of the single-channel desalination module 100 and the dual-channel desalination module 200 can meet the requirement.
Specifically, when the conductivity data detected by the conductivity detection module 10 on the first outlet side of the single channel desalination module 100 is not less than the target conductivity, it can be determined that the single channel desalination module 100 requires regeneration processing. When the conductivity data detected by the conductivity detection assembly 10 on the second outlet side of the dual-channel desalination assembly 200 is not less than the target conductivity, it can be determined that the dual-channel desalination assembly 200 requires regeneration processing.
For example, when the duration of time during which the conductivity data detected by the conductivity detection assembly 10 on the first outlet side of the single-channel desalination assembly 100 or the conductivity detection assembly 10 on the second outlet side of the dual-channel desalination assembly 200 is not less than the target conductivity exceeds a preset time period, such as 10 hours, it can be determined that the regeneration process is required for the single-channel desalination assembly 100 or the dual-channel desalination assembly 200.

Illustratively, the control module 410 controls the power supply module 420 to cut off power supply to the single channel desalination module 100 or to apply a reverse voltage to the single channel desalination module 100, and controls the waterway switching device 340 to tangentially connect to the third pipeline 330, when the conductivity data detected by the conductivity detection module 10 at the first outlet side of the single channel desalination module 100 is not less than the target conductivity. Such that the salt ions attached to the single-channel desalination assembly 100 enter the water and exit the single-channel desalination assembly 100 with the water, and the flushed wastewater exits the first water outlet 110 of the single-channel desalination assembly 100 into the third pipe 330.
In some embodiments, as shown in fig. 1 and 2, a conductivity detection assembly 10 may be further disposed on the first pipeline 310, and the conductivity detection assembly 10 may be capable of detecting the quality of the water to be purified.
Illustratively, the conductivity detection module 10 is coupled to the control module 410. The control module 410 can control the power supply module 420 to adjust the power supply voltage to the single channel desalination module 100 based on the conductivity data detected by the conductivity detection module 10 in the first conduit 310. For example, the greater the conductivity data detected by the conductivity detection assembly 10 on the first conduit 310, the greater the voltage of the forward voltage applied by the power supply assembly 420 to the single channel desalination assembly 100 to enhance the effectiveness of the purification process.
In some embodiments, as shown in fig. 1 and 2, a flow sensing assembly 30 may also be provided on the first pipeline 310 and/or the second pipeline 320.

In some embodiments, the conductivity detection assembly 10 is disposed on the third conduit 330. When the single-channel desalination assembly 100 is de-energized or a reverse voltage is applied to the single-channel desalination assembly 100, the control assembly 410 determines the effectiveness of regeneration of the single-channel desalination assembly 100 based on the conductivity data detected by the conductivity detection assembly 10 in the third line 330.
Illustratively, water after flushing the single channel desalination assembly 100 can be drained through the third line 330, during which the conductivity detection assembly 10 on the third line 330 can detect conductivity data of the water after flushing the single channel desalination assembly 100. When the conductivity data is less than the predetermined conductivity, it can be determined that the saline flush in the single channel desalination assembly 100 is complete, the regeneration mode can be terminated, such as resuming the application of the forward voltage to the single channel desalination assembly 100, and the waterway switching device 340 can be controlled to switch tangentially to the second pipeline 320.
