Technical Field

[0002] In the prior art, reverse osmosis membranes are usually used for water purification. However, when using reverse osmosis membranes for water purification, a high-pressure pump is required to provide high water pressure, resulting in high energy consumption and a large amount of wastewater generated. The CDI (Capacitive Deionization) technology uses the electrochemical principle to remove impurity ions in water to achieve the effect of water purification, and has the advantages of low energy consumption and small amount of wastewater.

[0003] However, in the existing CDI water purification, water treatment is usually carried out by continuous charging without precise control of the CDI. Since the electrochemical adsorption area of the CDI gradually decreases with the duration of power-on during water purification, that is, the water purification efficiency decreases, there is a problem that the quality of the effluent decreases after a long duration, and it will also affect the service life of the CDI.

[0034] Reference Figure 1 and Figure 2 , the present utility model provides a water purification assembly, including:

[0035] A control module 100, a water inlet module 200, and a water outlet module 300;

[0036] A capacitive deionization module 400, which is respectively connected to the water inlet module 200 and the water outlet module 300. The water outlet module 300 includes a purified water end and a wastewater end;

[0037] A power supply driving module 500, which is electrically connected to the capacitive deionization module 400, and the control module 100 is electrically connected to the controlled end of the power supply driving module 500;

[0038] The total dissolved solids detection module 600 is electrically connected to the control module 100, and the total dissolved solids detection module 600 is respectively connected to the water inlet module 200 and the water outlet module 300;

[0039] Among them, the control module 100 is used to control the working conditions of the capacitive deionization module 400 through the power supply driving module 500 according to the detection signal of the total dissolved solids detection module 600.

[0040] The water inlet module 200 obtains the water flow to be purified from the water inlet source. After the water flow to be purified passes through the capacitive deionization module 400 for purification treatment, a purified water flow is formed and output through the purified water end of the water outlet module 300. During this process, the total dissolved solids detection module 600 detects the total dissolved solids of the water flow in the water inlet module 200 and the water outlet module 300 to form corresponding detection signals and transmits them to the control module 100. The control module 100 controls the working conditions of the capacitive deionization module 400 through the power supply driving module 500. The control module 100 controls the capacitive deionization module 400 to charge through the power supply driving module 500 to adsorb ions for water purification treatment, controls the capacitive deionization module 400 to reverse charge to desorb ions and restore the adsorption area of the capacitor to improve the water purification efficiency. The waste water formed by desorbing ions is discharged through the waste water end of the water outlet module 300.

[0041] In this way, based on the total dissolved solids, the control module 100 can obtain information such as the water purification efficiency of the capacitive deionization module 400. When the water purification efficiency of the capacitive deionization module 400 drops to the preset range, the control module 100 timely controls the capacitive deionization module 400 to reverse charge to desorb ions and discharge the waste water, and then re-controls the capacitive deionization module 400 to charge for water purification treatment, which can maintain the water purification efficiency of the capacitive deionization module 400 within the target range, is beneficial to ensuring the water quality of the outlet, and can also timely desorb the ions adsorbed by the capacitive deionization module 400, which is beneficial to extending the service life of the capacitive deionization module 400.

[0042] Total Dissolved Solids (TDS) refers to the total amount of all solid substances dissolved in water, including various inorganic salts such as calcium, magnesium, sodium, potassium, carbonates, chlorides, sulfates, etc., and a small amount of organic matter. Total dissolved solids is an important indicator to measure the concentration of dissolved substances in water and is usually used to evaluate water quality.

[0043] It can be understood that based on the detection signals of the total dissolved solids detection module 600 for the water inlet module 200 and the water outlet module 300, the control module 100 can obtain the total dissolved solids of the inlet water and the total dissolved solids of the outlet water, and then know the water purification efficiency of the capacitive deionization module 400 according to the difference between the two. At the same time, the control module 100 can also judge whether to carry out water purification treatment according to the total dissolved solids of the inlet water.

[0044] In some embodiments of the present utility model, the control module 100 may be an implementation manner including devices or modules with control and processing functions such as a single-chip microcomputer, an embedded chip, an FPGA, etc.

[0045] In some embodiments of the present utility model, the capacitive deionization module 400 includes a first electrode plate and a second electrode plate. When the control module 100 controls the charging of the capacitive deionization module 400 through the power supply driving module 500, a voltage difference is applied between the first electrode plate and the second electrode plate, and the first electrode plate and the second electrode plate carry opposite charges. When water flows between the first electrode plate and the second electrode plate, the positive ions and negative ions formed by dissolved solids in the water will be adsorbed by the first electrode plate and the second electrode plate, reducing the total dissolved solids in the water to achieve water purification treatment. As the first electrode plate and the second electrode plate adsorb ions, the adsorption area will gradually decrease with the duration, that is, the water purification efficiency decreases, and if the ion adsorption time is too long, it may cause the ions to combine with the electrode plates, and then they cannot be desorbed, affecting the service life. Therefore, when the water purification efficiency is lower than the preset threshold, the control module 100 controls the capacitive deionization module 400 to perform reverse charging through the power supply driving module 500, so that a reverse voltage difference is applied between the first electrode plate and the second electrode plate, and then the first electrode plate and the second electrode plate carry the same charges as the adsorbed ions. Based on the repulsion of like-polarity charges, the ions on the first electrode plate and the second electrode plate will desorb into the water flow and form wastewater for discharge.

[0046] In some embodiments of the present utility model, the control module 100 may be based on the total dissolved solids of the water inlet module 200. When the total dissolved solids of the inlet water are greater than the start threshold, the control module 100 controls the capacitive deionization module 400 to charge through the power supply driving module 500 for water purification treatment; the control module 100 determines the water purification efficiency of the electronic deionization module according to the total dissolved solids. When the water purification efficiency is lower than the preset threshold, the control module 100 controls the capacitive deionization module 400 to perform reverse charging through the power supply driving module 500 to desorb ions and recharge for water purification, which can improve the water purification efficiency.

[0047] Reference Figure 2 In some embodiments of the water purification assembly of the present utility model, the power supply driving module 500 includes a wireless power supply unit 510 and a charge and discharge driving unit 520. The wireless power supply unit 510 is electrically connected to the input end of the charge and discharge driving unit 520, the output end of the charge and discharge driving unit 520 is electrically connected to the capacitive deionization module 400, and the control module 100 is electrically connected to the controlled end of the charge and discharge driving unit 520.

[0048] The wireless power supply unit 510 obtains a wireless signal, converts it into electrical energy, and transmits the electrical energy to the charge and discharge driving unit 520, thereby realizing the power supply to the charge and discharge driving unit 520. Furthermore, the charge and discharge driving unit 520 is controlled by the control module 100 to charge, reverse charge, etc. the capacitive deionization module 400. In this way, obtaining electrical energy wirelessly can reduce the dependence on a wired power supply interface, and at the same time facilitate waterproof design, which is beneficial to reducing the risks of circuit leakage and short circuit and improving reliability.

[0049] In some embodiments of the present utility model, the wireless power supply unit 510 can also supply power to the control module 100.

[0050] In some embodiments of the present utility model, the power supply driving module 500 can also be an embodiment including a wired power supply unit and the charge and discharge driving unit 520. The wired power supply unit obtains electrical energy through a wired connection and transmits the electrical energy to the charge and discharge driving unit 520.

[0051] Reference Figure 2 , in some embodiments of the water purification assembly of the present utility model, the wireless power supply unit 510 includes a wireless power supply receiver 511 and a DC conversion circuit 512. The wireless power supply receiver 511 is electrically connected to the input end of the DC conversion circuit 512, and the output end of the DC conversion circuit 512 is electrically connected to the input end of the charge and discharge driving unit 520.

[0052] Since the wireless signal is an AC signal, there are fluctuations in the electrical energy generated when the wireless power supply receiver 511 receives the wireless signal and converts it. By transmitting the electrical energy to the DC conversion circuit 512, the DC conversion circuit 512 performs DC conversion on the obtained electrical energy to form a stable DC voltage and transmits it to the charge and discharge driving unit 520. In this way, the DC conversion circuit 512 can convert the fluctuating electrical energy generated by the wireless power supply receiver 511 into stable electrical energy, which is beneficial to stably supplying power to the charge and discharge driving unit 520, so that the charging and reverse charging states of the capacitive deionization module 400 are more stable and reliable.

[0053] In some embodiments of the present utility model, the wireless power supply unit 510 can also include a storage battery. The DC conversion circuit 512 is connected to the storage battery to charge the storage battery with the excess electrical energy when the capacitive deionization module 400 is idle. The storage battery can maintain the power supply to the charge and discharge driving unit 520 when there is no wireless signal for power supply.

[0054] Reference Figure 2 and Figure 3, in some embodiments of the water purification assembly of the present utility model, the charge and discharge driving unit 520 includes a first switching tube S1, a second switching tube S2, a third switching tube S3, and a fourth switching tube S4. One end of the first switching tube S1 is electrically connected to the positive output terminal of the wireless power supply unit 510 and one end of the third switching tube S3 respectively. The other end of the first switching tube S1 is electrically connected to one end of the second switching tube S2 and the capacitive deionization module 400 respectively. The other end of the third switching tube S3 is electrically connected to one end of the fourth switching tube S4 and the capacitive deionization module 400 respectively. The other ends of the second switching tube S2 and the fourth switching tube S4 are both electrically connected to the negative output terminal of the wireless power supply unit 510. The control module 100 is electrically connected to the controlled terminals of the first switching tube S1, the second switching tube S2, the third switching tube S3, and the fourth switching tube S4 respectively.

[0055] Reference Figure 3 And Figure 4 , when the control module 100 controls the first switching tube S1 and the fourth switching tube S4 to conduct, and the second switching tube S2 and the third switching tube S3 to cut off, the capacitive deionization module 400 is charged to perform ion adsorption to achieve water purification treatment; reference Figure 3 And Figure 6 , when the control module 100 controls the first switching tube S1 and the fourth switching tube S4 to cut off, and the second switching tube S2 and the third switching tube S3 to conduct, the capacitive deionization module 400 is reversely charged to perform ion desorption to generate wastewater. In this way, the control module 100 realizes the control of the working condition of the capacitive deionization module 400 by controlling the on and off states of the first switching tube S1, the second switching tube S2, the third switching tube S3, and the fourth switching tube S4. The circuit structure is simple and easy to implement, and the control is flexible.

[0056] Reference Figure 2 And Figure 3 , in some embodiments of the water purification assembly of the present utility model, the charge and discharge driving unit 520 further includes a fifth switching tube S5 and a discharge resistor R1. One end of the fifth switching tube S5 is electrically connected to the other end of the first switching tube S1, the capacitive deionization module 400, and one end of the second switching tube S2 respectively. The other end of the fifth switching tube S5 is electrically connected to one end of the discharge resistor R1. The other end of the discharge resistor R1 is electrically connected to the other end of the third switching tube S3, the capacitive deionization module 400, and one end of the fourth switching tube S4 respectively. The control module 100 is electrically connected to the controlled terminal of the fifth switching tube S5.

[0057] Since the capacitive deionization module 400 is similar to a capacitor and stores electrical energy in the charging state, when it switches to the reverse charging state, it needs to release the stored electrical energy. During the process of the capacitive deionization module 400 transitioning from the charging state to the reverse charging state, in order to prevent the current formed by the released electrical energy from superimposing with the reverse charging current and causing excessive current to damage the devices in the circuit, a series branch is formed by connecting the fifth switching tube S5 in series with the discharge resistor R1 and is connected in parallel with the capacitive deionization module 400 to safely release the electrical energy stored in the capacitive deionization module 400.

[0058] Referring to Figure 3 and Figure 4 , in the charging state, that is, when the first switching tube S1 and the fourth switching tube S4 are conducting, and the second switching tube S2 and the third switching tube S3 are cut off, the fifth switching tube S5 is cut off, and the discharge resistor R1 does not affect the capacitive deionization module 400. In situations such as when the water purification efficiency is too low and reverse charging is required, referring to Figure 3 and Figure 5 , first, the control module 100 controls the first switching tube S1, the second switching tube S2, the third switching tube S3, and the fourth switching tube S4 to be cut off, and the fifth switching tube S5 to be conducting, so that the capacitive deionization module 400 forms a loop with the discharge resistor R1. The capacitive deionization module 400 releases the stored electrical energy to form a current, and the current converts the electrical energy into heat energy through the discharge resistor R1 and consumes it; then, referring to Figure 3 and Figure 6 , the control module 100 controls the first switching tube S1, the fourth switching tube S4, and the fifth switching tube S5 to be cut off, and the second switching tube S2 and the third switching tube S3 to be conducting to reverse charge the capacitive deionization module 400.

[0059] In this way, through the structure of the fifth switching tube S5 and the discharge resistor R1, the effect of safely releasing the electrical energy stored in the capacitive deionization module 400 is achieved, which is beneficial to improving the safety and stability of the circuit.

[0060] In some embodiments of the present utility model, the first switching tube S1, the second switching tube S2, the third switching tube S3, the fourth switching tube S4, and the fifth switching tube S5 can be implemented using transistors with switching functions such as field effect transistors and triodes.

The first valve member 210, the pump member 220, and the filter member 230 are arranged in sequence according to the water flow direction. The input end of the water inlet pipe is used to connect to a water source, and the output end of the water inlet pipe is connected to the capacitive deionization module 400. The control module 100 is electrically connected to the controlled end of the first valve member 210 and the controlled end of the pump member 220 respectively.

[0062] Driven by the pump member 220, the water from the water source flows into the input end of the water inlet pipe, and flows through the first valve member 210, the pump member 220, and the filter member 230 in sequence, and then flows to the capacitive deionization module 400. By controlling the operating conditions of the pump member 220, the control module 100 can control the flow rate and start / stop of the purified water. By controlling the on / off state of the first valve member 210, the control module 100 can control the connection state with the water source. The filter member 230 is used to filter large particle solids, insoluble impurities and other objects in the water to preliminarily purify the water, and realizes the purification treatment of the water in combination with the capacitive deionization module 400.

[0063] Reference Figure 1 and Figure 2 , in some embodiments of the water purification component of the present utility model, the water outlet module 300 includes a purified water pipe, a waste water pipe, a second valve member 310, and a third valve member 320. The input end of the purified water pipe and the input end of the waste water pipe are both connected to the capacitive deionization module 400.

The control module 100 is electrically connected to the controlled end of the second valve member 310 and the controlled end of the third valve member 320 respectively.

[0064] By controlling the on / off state of the second valve member 310 and the third valve member 320, the control module 100 can control the water flow to be discharged from the purified water pipe or the waste water pipe. When the control module 100 controls the capacitive deionization module 400 to charge through the power supply driving module 500, it controls the second valve member 310 to be conductive and the third valve member 320 to be cut off, so that the water purified by the capacitive deionization module 400 is discharged from the purified water pipe; when the control module 100 controls the capacitive deionization module 400 to discharge and reverse charge, it controls the second valve member 310 to be cut off and the third valve member 320 to be conductive, so that the waste water generated by the capacitive deionization module 400 is discharged from the waste water pipe. In this way, it can cooperate with the operating conditions of the capacitive deionization module 400 to control the drainage pipeline, and the control is more flexible and convenient.

[0066] By arranging a sterilization component 330 to be connected to the purified water pipe, the purified water is sterilized and then discharged from the purified water pipe, which is beneficial to further improve the quality of the discharged water and meet the usage requirements.

[0067] In some embodiments of the present utility model, the sterilization component 330 can be a sterilization lamp to achieve sterilization through ultraviolet irradiation; it can also include an ultraviolet lamp and a titanium dioxide photocatalytic layer, and active oxygen such as hydroxyl radicals can be generated by combining titanium dioxide under the irradiation of ultraviolet light to achieve sterilization.

[0068] Reference Figure 1 and Figure 2 Referring to and, in some embodiments of the water purification assembly of the present utility model, the total dissolved solids detection module 600 includes a first total dissolved solids sensor 610, a second total dissolved solids sensor 620, and a third total dissolved solids sensor 630, all of which are electrically connected to the control module 100. The first total dissolved solids sensor 610 is connected to the water inlet pipe, the second total dissolved solids sensor 620 is connected to the purified water pipe, and the third total dissolved solids sensor 630 is connected to the wastewater pipe.

[0069] The control module 100 obtains the detection signals of the first total dissolved solids sensor 610, the second total dissolved solids sensor 620, and the third total dissolved solids sensor 630, and can correspondingly obtain the total dissolved solids of the water inlet pipe, the total dissolved solids of the purified water pipe, and the total dissolved solids of the wastewater pipe. Then, based on this, the working condition of the capacitive deionization module 400 is controlled by the power supply driving module 500. The control module 100 determines whether to perform water purification treatment according to the total dissolved solids of the water inlet pipe, and then starts or stops the water purification treatment process; the control module 100 can determine the water purification efficiency of the capacitive deionization module 400 according to the total dissolved solids of the purified water pipe in combination with the total dissolved solids of the water inlet pipe. Then, when the water purification efficiency drops to a preset threshold, the control module 100 controls the capacitive deionization module 400 to perform reverse charging to maintain the water purification efficiency and ensure the quality of the discharged water; the control module 100 can know the ion desorption progress of the capacitive deionization module 400 according to the total dissolved solids of the wastewater pipe, and then determine the time to end the reverse charging. In this way, the control module 100 can monitor the overall water purification treatment process through the first total dissolved solids sensor 610, the second total dissolved solids sensor 620, and the third total dissolved solids sensor 630, which is beneficial to realizing precise control of the capacitive deionization module 400 and improving the accuracy and flexibility of control.

[0070] The present utility model also provides a water purification device, including a device body, and the device body includes the above-mentioned water purification assembly.

[0071] In the device body, the water inlet module 200 obtains the water flow to be purified from the water inlet source. After the water flow to be purified undergoes purification treatment through the capacitive deionization module 400, the purified water flow flows out through the purified water end of the water outlet module 300. During this process, the total dissolved solids detection module 600 detects the total dissolved solids of the water flow in the water inlet module 200 and the water outlet module 300 to form corresponding detection signals and transmits them to the control module 100. The control module 100 controls the operating conditions of the capacitive deionization module 400 through the power supply driving module 500 based on the detection signals. The control module 100 controls the capacitive deionization module 400 to charge through the power supply driving module 500 to adsorb ions for water purification treatment, controls the capacitive deionization module 400 to reverse charge to desorb ions and restore the adsorption area of the capacitor, improves the water purification efficiency, and the wastewater formed by the desorbed ions is discharged through the wastewater end of the water outlet module 300.

[0072] Thus, based on the total dissolved solids, the control module 100 can obtain information such as the water purification efficiency of the capacitive deionization module 400. When the water purification efficiency of the capacitive deionization module 400 drops to the preset range, the control module 100 timely controls the capacitive deionization module 400 to reverse charge to desorb ions and discharge the wastewater, and then re-controls the capacitive deionization module 400 to charge for water purification treatment, which can maintain the water purification efficiency of the capacitive deionization module 400 within the target range, is beneficial to ensuring the water quality of the outlet, and can also timely desorb the ions adsorbed by the capacitive deionization module 400, which is beneficial to extending the service life of the capacitive deionization module 400.
