Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Fig. 1 is a schematic structural diagram of the household water purifying device in the embodiment.

Referring to fig. 1, the household water purification apparatus includes a single-channel desalination module 100 and a pipeline system 200.

As shown in fig. 1, the single channel desalination assembly 100 includes a first water inlet 110 and a first water outlet 120, and when a positive voltage is applied, the water flowing in from the first water inlet 110 is purified, and the treated water flows out through the first water outlet 120.

Specifically, the piping system 200 includes a first pipe 210, a second pipe 220, a third pipe 230, and a three-way valve 240. The first pipeline 210 is used for delivering water to the first water inlet 110, the second water inlet 241 of the three-way valve 240 is connected to the first water outlet 120 of the single channel desalination assembly 100, the second water outlet 242 and the third water outlet 243 of the three-way valve 240 are correspondingly connected to the second pipeline 220 and the third pipeline 230, and the second pipeline 220 is used for outputting water purified by the single channel desalination assembly 100.

In some embodiments, as shown in fig. 2, the household water purifier further comprises a raw water tank 310 capable of storing water, and one end of the first pipeline 210 is connected to the raw water tank 310, and the other end is connected to the first water inlet 110 of the single channel desalination assembly 100.

Illustratively, the raw water tank 310 includes a transparent housing or a transparent window is provided on the housing, which is convenient for a user to view the water quality, water level, etc. in the raw water tank 310.

Illustratively, the raw water tank 310 may further include a water injection port through which water to be purified may be added to the raw water tank 310. For example, the water filling port is connected with a tap water pipe. Illustratively, a liquid level meter is further disposed in the raw water tank 310, and when the liquid level in the raw water tank 310 drops to a set value, a valve of a tap water pipe can be controlled to open to add water to a water inlet of the raw water tank 310.

Illustratively, the water stored in the raw water tank 310 may flow into the single channel desalination module 100 through the first pipeline 210, and when the single channel desalination module 100 applies a positive voltage, the flowing water is purified, and the purified water is output through the second pipeline 220. For example, the three-way valve 240 opens the second water inlet 241 and the second water outlet 242, so that the purified water can be conveniently output through the second pipeline 220.

It will be appreciated that first conduit 210 may also be connected directly to the tap water line at one end and to first water inlet 110 of single channel desalination assembly 100 at the other end.

It will be appreciated that the single-channel desalination assembly 100 uses only one water inlet and one water outlet for the purification of water flowing therethrough, and thus may be referred to as a single-channel desalination assembly.

The single channel desalination module 100 may not discharge wastewater when purifying water flowing therethrough. Through adopting the desalination subassembly of single current way to carry out the water purification, the water that gets into single current way desalination subassembly 100 can be followed the delivery port and discharged, obtains purification treatment simultaneously, does not produce waste water in this process, has improved the utilization ratio of water.

In some embodiments, the single-channel desalination assembly 100 comprises a physisorption desalination cartridge and/or a chemisorption desalination cartridge.

Illustratively, the chemisorptive desalination cartridge can include at least one of an ion exchange (IX) resin cartridge, a bipolar membrane (Biopolar, BP) desalination cartridge.

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 electrified, so that the water purification treatment is realized, and the filter elements can be called as electrically-driven single-channel desalination filter elements.

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.

For example, as shown in fig. 5, the household water purification device may further include a power supply module 420, and the power supply module 420 is connected to the electrically driven single-channel desalination filter element 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.

In this embodiment, as shown in fig. 1 and 2, a first conductivity detection assembly 10 is disposed between the first water outlet 120 and the three-way valve 240, or the first conductivity detection assembly 10 is disposed on the second pipeline 220. The water quality of water at the corresponding position can be detected through the conductivity detection component. 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.

By detecting the conductivity of the effluent at the effluent side of the single channel desalination assembly 100, it can be determined whether the water purification effectiveness of the single channel desalination assembly 100 can meet the requirements.

Specifically, when the conductivity data detected by the first conductivity detection module 10 is not less than the target conductivity, it can be determined that the single-channel desalination module 100 adsorbs more salts in the water purification process, and the single-channel desalination module 100 needs to be regenerated.

For example, when the duration of the conductivity data detected by the first conductivity detection assembly 10 is not less than the target conductivity for more than a predetermined period of time, such as 10 hours, it can be determined that the single channel desalination assembly 100 requires regeneration.

Specifically, the single channel desalination assembly 100 can be powered down or energized in the opposite direction to allow the saline substances in the single channel desalination assembly 100 to be flushed from the incoming water from the first water inlet 110 to the third conduit 230.

Illustratively, referring to fig. 1 and 2, when the first conduit 210 supplies water to the single channel desalination assembly 100, the power supply assembly 420 can apply a reverse voltage to the single channel desalination assembly 100 to cause salt ions attached to the single channel desalination assembly 100 to enter the water and exit the single channel desalination assembly 100 with the water. At this time, the three-way valve 240 may open the second water inlet 241 and the third water outlet 243 thereof, so that the flushed waste water may be discharged from the third water outlet 243 and the third pipeline 230, for example, to a water tank.

In some embodiments, as shown in fig. 2, the household water purifying apparatus further includes a waste water tank 320, and one end of the third pipe 230 is connected to the third water outlet 243 of the three-way valve 240, and the other end is connected to the waste water tank 320. The wastewater after flushing the single channel desalination assembly 100 can be discharged to a wastewater tank 320 connected to the third conduit 230.

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 household water purifying apparatus further comprises a control module 410 and a power supply module 420, wherein the control module 410 is connected to the first conductivity detection module 10, the power supply module 420 and the three-way valve 240, and the power supply 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 outlet control operation through an input device, such as a user pressing a water outlet button, or uttering a voice including a water outlet command, the control power supply module 420 applies a forward voltage to the single channel desalination module 100, and controls the three-way valve 240 to open the second water inlet 241 and the second water outlet 242, so that purified water purified by the single channel desalination module 100 can be output.

In some embodiments, the outlet direction of the second pipe 220 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 220 to provide the user with hot water of a desired temperature.

Illustratively, the water outlet direction of the second pipeline 220 is connected to a plurality of water outlet pipelines, and at least one of the water outlet pipelines is provided with a heating unit.

In some embodiments, the control component 410 controls the power supply component 420 to turn off the power to the single channel desalination assembly 100 or to apply a reverse voltage to the single channel desalination assembly 100 while controlling the three-way valve 240 to open the second water inlet 241 and the third water outlet 243 when the conductivity data detected by the first conductivity detection component 10 is not less than the target conductivity. 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. At this time, the three-way valve 240 may open the second water inlet 241 and the third water outlet 243 thereof, so that the flushed waste water may be discharged from the third water outlet 243 and the third pipeline 230, for example, to a water tank.

In some embodiments, as shown in FIG. 2, a second conductivity detection module 20 may be disposed in the first conduit 210, and the second conductivity detection module 20 may be capable of detecting the quality of the water requiring purification treatment by the single channel desalination module 100.

Illustratively, the second conductivity detection assembly 20 is coupled to the control assembly 410. The control component 410 can control the power supply component 420 to adjust the power supply voltage to the single channel desalination assembly 100 based on the conductivity data detected by the second conductivity detection component 20. For example, the greater the conductivity data detected by the second conductivity detection assembly 20, the greater the voltage of the forward voltage applied by the power supply assembly 420 to the single channel desalination assembly 100 to increase the effectiveness of the decontamination process.

In some embodiments, as shown in fig. 2, a flow detection assembly 30 may be further disposed on the first pipeline 210, and the flow detection assembly 30 is connected to the control assembly 410.

Illustratively, the control component 410 can determine a consumption value for the single channel desalination assembly 100 based on the conductivity data detected by the first conductivity detection component 10, the conductivity data detected by the second conductivity detection component 20, and the flow data detected by the flow detection component 30. For example, the desalination throughput of the single channel desalination assembly 100 can be determined from conductivity data of the water flowing into the single channel desalination assembly 100 and conductivity data of the water flowing out of the single channel desalination assembly 100, and as the flow rates of the water processed by the single channel desalination assembly 100 accumulate, the total amount of adsorbed salt species in the single channel desalination assembly 100 can be determined, which can represent the consumption value of the single channel desalination assembly 100.

Illustratively, the control component 410 can control the power supply component 420 to de-energize the single channel desalination assembly 100 or apply a reverse voltage to the single channel desalination assembly 100 while controlling the three-way valve 240 to open the second water inlet 241 and the third water outlet 243 when the consumption value is not less than the consumption threshold.

For example, when the salt absorption capacity of the single-channel desalination assembly 100 is Q, the depletion threshold can be determined to be 0.75Q; when the cumulative consumption value of the single-channel desalination assembly 100 reaches the consumption threshold, the regeneration mode is switched to regenerate the single-channel desalination assembly 100 to restore the salt absorption capacity of the single-channel desalination assembly 100.

When switching to the regeneration mode, the control module 410 controls the power supply module 420 to apply a reverse voltage to the single channel desalination module 100 so that the salt ions attached to the single channel desalination module 100 enter the water and exit the single channel desalination module 100 with the water, and the control module 410 controls the three-way valve 240 to open the second water inlet 241 and the third water outlet 243 thereof so that the flushed waste water is discharged from the third water outlet 243 and the third pipeline 230, for example, to the waste water tank 320.

In some embodiments, the first conductivity detection assembly 10 is disposed between the first water outlet 120 and the three-way valve 240. Upon de-energizing the single channel desalination assembly 100 or applying a reverse voltage to the single channel desalination assembly 100, the control assembly 410 determines the regeneration effect of the single channel desalination assembly 100 based on the conductivity data detected by the first conductivity detection assembly 10.

Illustratively, the water after flushing the single-channel desalination assembly 100 can be discharged through the three-way valve 240 and the second line 220, during which the first conductivity detection assembly 10 can detect conductivity data of the water after flushing the single-channel desalination assembly 100. When the conductivity data detected by the first conductivity detection assembly 10 is less than the predetermined conductivity, it can be determined that the saline material in the single channel desalination assembly 100 is flushed, the regeneration mode can be terminated, such as resuming the application of the forward voltage to the single channel desalination assembly 100, and the three-way valve 240 can be controlled to open the second water inlet 241 and the second water outlet 242.

Illustratively, the control component 410 can determine the regeneration effectiveness of the single channel desalination assembly 100 based on the conductivity data detected by the first conductivity detection component 10 and the flow rate data detected by the flow rate detection component 30. The amount of salt released by flushing the single-channel desalination assembly 100 during the production process can thus be determined, for example, the regeneration mode can be terminated when the amount of released salt reaches a predetermined release threshold, such as 80% -150% of the salt absorption capacity Q.

In some embodiments, as shown in fig. 2, the conduit system 200 further comprises a drive assembly 250 disposed on the first conduit 210, the drive assembly 250 driving water to the single channel desalination assembly 100.

Illustratively, the drive assembly 250 may comprise a self-priming pump. When the single-channel desalination assembly 100 is in operation, the driving assembly 250 drives the water in the raw water tank 310 to flow to the single-channel desalination assembly 100, which can increase the flow rate of the discharged water and avoid the user waiting for a long time when receiving water.

In some embodiments, conduit system 200 further includes a filter assembly 260 disposed on first conduit 210 and/or a filter assembly 260 disposed on second conduit 220.

Illustratively, the filter assembly 260 may include a PP cotton filter element and/or an activated carbon filter element. The filter assembly 260 in the first line 210 can purify the water entering the single channel desalination assembly 100, 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 260 on the second pipe 220 can further improve the quality of the pure water outputted from the domestic water purifying apparatus.
