[0055] The following Figures 1 to 14 will, through specific embodiments and their application scenarios, provide a detailed description of the water purification component and the water purification device provided by the embodiments of the present utility model.

[0056] In the first aspect, as Figure 1 、 Figure 2 and Figure 3 shown, the water purification component of the embodiments of the present utility model includes: a housing 1 and a capacitive deionization filter element 2. Among them, the housing 1 has a water inlet port 101 and a water outlet port 102, and the water inlet port 101 and the water outlet port 102 are located on the same side of the housing 1.

[0057] The capacitive deionization filter element 2 is disposed within the housing 1. An outlet space 111 and a receiving space 112 that are isolated from each other are formed between the first end of the capacitive deionization filter element 2 and the inner wall of the housing 1. The receiving space 112 is located outside the outlet space 111. A gap is left between the outer side surface of the capacitive deionization filter element 2 and the inner wall of the housing 1. The capacitive deionization filter element 2 has an inlet end in its radial direction and an outlet 213 in its axial direction.

[0058] Wherein, the inlet port 101 communicates with the gap, and the outlet 213, the outlet space 111, and the outlet port 102 are communicated in sequence. The positive electrode tab 201 and the negative electrode tab 202 of the capacitive deionization filter element 2 both extend into the receiving space 112. The positive electrode tab 201 and the negative electrode tab 202 are spaced apart and are adapted to be connected to an external power source.

[0059] It can be understood that the housing 1 is columnar, a receiving cavity is provided within the housing 1, and the capacitive deionization filter element 2 is installed in the receiving cavity and is configured to be coaxially arranged with the housing 1. The inlet port 101 and the outlet port 102 are respectively located at the first end of the housing 1 and communicate with the receiving cavity.

[0060] An outlet space 111 and a receiving space 112 that are isolated from each other are formed between the first end of the capacitive deionization filter element 2 and the inner wall of the first end of the housing 1. The second end of the capacitive deionization filter element 2 abuts against the inner wall of the second end of the housing 1. Since the positive electrode tab 201 and the negative electrode tab 202 of the capacitive deionization filter element 2 are disposed in the receiving space 112, and the outlet 213 of the capacitive deionization filter element 2 is disposed in the outlet space 111, this design realizes the electrical and water isolation of the water purification assembly based on the mutually isolated outlet space 111 and receiving space 112, ensuring the reliability of the water purification work of the water purification assembly.

[0061] In some embodiments, as Figure 2 and Figure 3 shown, a first partition 121 and a second partition 122 are provided on the inner wall of the housing 1. The second partition 122 is located outside the first partition 121. The first partition 121 and the first end of the capacitive deionization filter element 2 enclose the outlet space 111, and the first partition 121, the second partition 122, and the first end of the capacitive deionization filter element 2 enclose the receiving space 112.

[0062] It can be understood that the first partition 121 and the second partition 122 are respectively disposed on the inner wall of the first end of the housing 1. The outlet port 102 is disposed at the center of the first end of the housing 1. The first partition 121 and the second partition 122 respectively extend circumferentially in a ring shape with respect to the outlet port 102. Since the second partition 122 is located outside the first partition 121, the receiving space 112 is located outside the outlet space 111.

[0063] In practical applications, simply abut the first end of the capacitive deionization filter element 2 against the inner wall of the first end of the housing 1, and based on the first partition plate 121 and the second partition plate 122, a water outlet space 111 and a receiving space 112 can be formed between the first end of the capacitive deionization filter element 2 and the first end of the housing 1.

[0064] In some embodiments, such as Figure 2 , Figure 3 , Figure 8 and Figure 11 shown, the water purification assembly further includes: a first end cap 3;

[0065] The first end cap 3 includes a side wall 31 and a top wall 32 that are bent and connected. The side wall 31 is sealingly connected to the inner side surface of the second partition plate 122, and the top wall 32 is sealingly connected to the first end of the capacitive deionization filter element 2. The top wall 32 is clamped between the first end of the capacitive deionization filter element 2 and the second partition plate 122.

[0066] Among them, the positive electrode tab 201 and the negative electrode tab 202 are located in the area enclosed by the side wall 31 and the first partition plate 121.

[0067] It can be understood that the top wall 32 is disc-shaped, the top wall 32 is provided with a central hole, the central hole is coaxially arranged with the water outlet port 102, the side wall 31 extends circumferentially relative to the central hole, and the positive electrode tab 201, the negative electrode tab 202 and the water outlet 213 of the capacitive deionization filter element 2 pass through the central hole.

[0068] When the first end of the capacitive deionization filter element 2 abuts against the inner wall of the first end of the housing 1, the outer side surface of the side wall 31 is sealingly connected to the inner side surface of the second partition plate 122, and a closed receiving space 112 is formed between the side wall 31, the first partition plate 121 and the first end of the capacitive deionization filter element 2. The waterproof isolation of the positive electrode tab 201 and the negative electrode tab 202 can be realized based on the receiving space 112.

[0069] At the same time, the peripheral wall of the water outlet 213 and the inner side surface of the first partition plate 121 can also be configured to be sealingly connected. This design can ensure that the water output from the water outlet 213 directly discharges from the water outlet port 102 after entering the water outlet space 111, and the water in the water outlet space 111 will not flow into the receiving space 112.

[0070] In some embodiments, such as Figure 2 , Figure 3 and Figure 8 shown, the first end cap 3 further includes: a first glue blocking wall 33, the first glue blocking wall 33 is bent and connected to the top wall 32, the top wall 32 and the first end of the capacitive deionization filter element 2 are sealingly connected by filling glue, and the inner side surface of the first glue blocking wall 33 is attached to the peripheral wall of the capacitive deionization filter element 2;

[0071] Among them, there is a water passing gap between the outer side surface of the first glue blocking wall 33 and the inner wall of the housing 1, and the water inlet port 101 is communicated with the gap through the water passing gap.

[0072] It can be understood that the filling glue can be epoxy resin glue, and the filling glue forms a sealing glue layer at the first end of the capacitive deionization filter element 2. The first glue blocking wall 33 is arranged on the outer edge along the top wall 32 and extends circumferentially relative to the central hole. The inner diameter of the first glue blocking wall 33 is adapted to the diameter of the capacitive deionization filter element 2.

[0073] Optionally, in order to ensure the sealing effect on the first end of the capacitive deionization filter element 2, a first support rib is arranged on the side surface of the top wall 32 facing the capacitive deionization filter element 2. The first support rib can be configured to extend radially along the water outlet pipe 21. The first support rib is used to ensure the filling thickness of the filling glue at the first end of the capacitive deionization filter element 2 and is beneficial to ensuring the molding quality of the filling glue.

[0074] In an alternative embodiment, as Figure 12 shown, in order to ensure the molding quality of the filling glue, a glue blocking plate 321 is further arranged on the side surface of the top wall 32 facing the capacitive deionization filter element 2 and is arranged close to the side wall 31. That is to say, the glue blocking plate 321 is arranged on the inner edge along the top wall 32 and extends circumferentially relative to the central hole. The glue blocking plate 321 is used to limit the flow of the filling glue towards the area where the central hole is located.

[0075] In an alternative embodiment, as Figure 8 and Figure 11 shown, a plurality of spaced-apart abutting portions 332 are arranged on the outer side surface of the first glue blocking wall 33, and the abutting portions 332 are in contact with the inner wall of the housing 1.

[0076] In other words, bumps can be arranged on the outer side surface of the first glue blocking wall 33, and the bumps are in contact with the inner wall of the housing 1 so as to form a water passing gap between the outer side surface of the first glue blocking wall 33 and the inner wall of the housing 1.

[0077] In some embodiments, as Figure 2 、 Figure 3 、 Figure 10 and Figure 11 shown, the water purification assembly further includes: a second end cover 4;

[0078] The second end cover 4 includes a bottom wall 41 and a second glue blocking wall 42 which are bent and connected. The bottom wall 41 is hermetically connected to the second end of the capacitive deionization filter element 2 through filling glue, and the second glue blocking wall 42 is attached to the peripheral wall of the capacitive deionization filter element 2.

[0079] It can be understood that the bottom wall 41 is in a disc shape, the filling glue forms a sealing glue layer at the second end of the capacitive deionization filter element 2, and the bottom wall 41 is attached to the surface of the sealing glue layer to realize the sealing of the second end of the capacitive deionization filter element 2.

[0080] The second glue-blocking wall 42 is provided on the outer edge of the bottom wall 41 and extends circumferentially relative to the center of the bottom wall 41. The inner diameter of the second glue-blocking wall 42 is adapted to the diameter of the capacitive deionization filter element 2. The second glue-blocking wall 42 is used to prevent the filling glue from overflowing to the peripheral wall of the capacitive deionization filter element 2.

[0081] Further, a second support rib may also be provided on the side of the bottom wall 41 facing the capacitive deionization filter element 2. The second support rib may be configured to extend radially along the water outlet pipe 21. The second support rib is used to ensure the thickness of the filling glue filled at the second end of the capacitive deionization filter element 2 and is beneficial to ensuring the forming quality of the filling glue.

[0082] As Figure 1 、 Figure 8 、 Figure 9 and Figure 11 shown, the housing 1 is provided with a first through hole 103 and a second through hole 104 communicating with the accommodation space 112. The first through hole 103, the second through hole 104, the water outlet port 102 and the water inlet port 101 are located on the same side of the housing 1. Among them, the first through hole 103 corresponds to the positive electrode tab 201, and the second through hole 104 corresponds to the negative electrode tab 202. Exemplarily, the positive electrode tab 201 can pass through the first through hole 103, and the negative electrode tab 202 can pass through the second through hole 104. In this way, the external power supply of the positive electrode tab 201 and the negative electrode tab 202 can be realized.

[0083] As Figure 8 、 Figure 9 and Figure 11 shown, the water purification assembly further includes an annular fixing seat 6 and an electricity connection assembly 5. The electricity connection assembly 5 includes a positive electricity connecting member 51 and a negative electricity connecting member 52. The annular fixing seat 6 is coaxially arranged on the side wall 31. The annular fixing seat 6 is located in the accommodation space 112. The annular fixing seat 6 is provided with a first positioning hole 611 corresponding to the positive electrode tab 201 and a second positioning hole corresponding to the negative electrode tab 202. The positive electricity connecting member 51 is inserted into the first positioning hole 611 and is detachably connected to the positive electrode tab 201. The negative electricity connecting member 52 is inserted into the second positioning hole and is detachably connected to the negative electrode tab 202. In addition, the positive electricity connecting member 51 sequentially passes through the first positioning hole 611 and the first through hole 103, and the negative electricity connecting member 52 sequentially passes through the second positioning hole and the second through hole 104.

[0084] Specifically, the annular fixing base 6 is detachably arranged on the side wall 31. The annular fixing base 6 includes a top plate 61 and a side plate 62 which are bent and connected. The top plate 61 abuts against the side of the side wall 31 away from the top wall 32. The top plate 61 is provided with a first positioning hole 611 and a second positioning hole. The side plate 62 abuts against the inner side surface of the side wall 31. Among them, the side plate 62 is provided with a clamping groove 621, and the inner side surface of the side wall 31 is provided with a clamping buckle 311. The annular fixing base 6 and the first end cover 3 are limited and matched in the circumferential direction through the clamping groove 621 and the clamping buckle 311.

[0085] As Figure 9 shown, each of the first positioning hole 611 and the second positioning hole is a stepped hole, the stepped hole is provided with a stepped surface, and the outer side surface of each of the positive electrode electrical connector 51 and the negative electrode electrical connector 52 is provided with an abutting surface, and the abutting surface abuts against the stepped surface.

[0086] In addition, each of the positive electrode electrical connector 51 and the negative electrode electrical connector 52 is provided with a slot, and the corresponding tab is inserted into the slot. For example, the bottom of the positive electrode electrical connector 51 is provided with a slot, and the positive tab 201 can be inserted into the slot of the positive electrode electrical connector 51.

[0087] In practical applications, such as Figure 8 , Figure 9 , Figure 10 and Figure 11As shown in the figure, first, a layer of filling glue is provided in the first region at the first end of the capacitive deionization filter element 2. The first region is disposed axially opposite to the top wall 32 along the housing 1. Then, the first end cap 3 is covered on the first end of the capacitive deionization filter element 2. Since the first glue-blocking wall 33 is attached to the peripheral wall of the capacitive deionization filter element 2 and the first glue-blocking wall 33 extends circumferentially relative to the water outlet port 102, the first glue-blocking wall 33 can not only prevent the filling glue from overflowing to the side of the capacitive deionization filter element 2, but also limit the capacitive deionization filter element 2 radially to ensure the coaxiality of the capacitive deionization filter element 2 and the water outlet port 102. Next, a layer of filling glue is provided in the second region at the first end of the capacitive deionization filter element 2. The second region corresponds to the region where the central hole is located on the top wall 32, thereby completing the sealing of the first end of the capacitive deionization filter element 2. Subsequently, the annular fixing seat 6 is installed on the side wall 31. Under the limiting cooperation of the clamping groove 621 and the clamping buckle 311, the first positioning hole 611 can correspond to the positive electrode tab 201, and the second positioning hole can correspond to the negative electrode tab 202. Then, the positive electrode electrical connector 51 is installed in the first positioning hole 611 and completes the plugging cooperation with the positive electrode tab 201, and the negative electrode electrical connector 52 is installed in the second positioning hole and completes the plugging cooperation with the negative electrode tab 202. That is to say, under the action of the annular fixing seat 6, the docking coaxiality of the electrical connector and the tab can be ensured, and it can be ensured that during the docking process of the electrical connector and the tab, the electrical connector will not move excessively so as not to damage the tab.

[0088] In an alternative embodiment, as Figure 8 and Figure 12 shown, the water purification assembly further includes a positioning structure. The positioning structure includes a groove 331 and a protrusion 11. The protrusion 11 is provided on the inner wall of the housing 1, and the groove 331 extends from the outer side surface of the top wall 32 to the outer side surface of the first glue-blocking wall 33. Thus, when assembling the capacitive deionization filter element 2 and the housing 1, the docking accuracy of the positive electrode electrical connector 51 and the first through hole 103, and the docking accuracy of the negative electrode electrical connector 52 and the second through hole 104 can be ensured. Among them, after the capacitive deionization filter element 2 is assembled to the housing 1, the top plate 61 of the annular fixing seat 6 can be sleeved on the outer side surface of the first partition plate 121. It should be noted that the housing 1 can be set as a first housing and a second housing. After the capacitive deionization filter element 2 is installed in the first housing, the first housing and the second housing are then connected.

[0089] As Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the capacitive deionization filter element 2 includes a water outlet pipe 21 and an electrode assembly 22. The electrode assembly 22 is wound around the peripheral wall of the water outlet pipe 21. The electrode assembly 22 is sealed at both ends along the axial direction of the water outlet pipe 21. The outer side of the electrode assembly 22 is used to receive the input of raw water, and the inner side of the electrode assembly 22 is used to output clean water or waste water.

[0090] The water outlet pipe 21 has a water outlet channel 211, a water hole 212 and a water outlet 213 communicated with the water outlet channel 211. The water outlet channel 211 is arranged in the water outlet pipe 21, the water outlet channel 211 is formed with the water outlet 213, and the water hole 212 is arranged on the peripheral wall of the water outlet pipe 21. Exemplarily, the water outlet 213 is arranged at the first end of the water outlet pipe 21, and the water hole 212 is arranged on the peripheral wall near the second end of the water outlet pipe 21.

[0091] It is understandable that the electrode assembly 22 generally includes positive and negative electrode sheets that are stacked, the positive and negative electrode sheets are isolated from each other, and a flow channel for water flow is formed between the positive and negative electrode sheets; when the electrode assembly 22 is wound, the inner side surface of one end of the electrode assembly 22 contacts the peripheral wall of the water outlet pipe 21, and then the electrode assembly 22 is wound layer by layer with the water outlet pipe 21 as the central axis until the electrode assembly 22 is wound in a columnar distribution.

[0092] Since the electrode assembly 22 is wound around the peripheral wall of the water outlet pipe 21 and the electrode assembly 22 is sealed at both ends along the axial direction of the water outlet pipe 21, when a positive voltage is applied to the positive electrode sheet and the negative electrode sheet, the cations, anions or charged particles in the water body will migrate to the surface of the positive electrode sheet and the negative electrode sheet under the action of the electric field force, so that the inner side of the electrode assembly 22 outputs the clean water after desalination treatment; when a reverse voltage is applied to the positive electrode sheet and the negative electrode sheet, or when the voltage is stopped, the anions, cations or charged particles adsorbed on the surface of the positive electrode sheet and the negative electrode sheet will automatically detach, so that the inner side of the electrode assembly 22 outputs wastewater with a higher concentration.

[0093] Considering that the peripheral wall of the existing water outlet pipe 21 is usually densely provided with a plurality of water passing holes 212, the water output from the inner side of the electrode assembly 22 will uniformly pass through each water passing hole 212 and enter the water outlet channel 211. If there are bubbles in the electrode assembly 22, the bubbles may adhere to the surface of the positive electrode plate and / or the negative electrode plate, and the flowing water body will not act on the desorption of the bubbles. However, in this application, by arranging the water passing holes 212 on the peripheral wall near the second end of the water outlet pipe 21, the water passing holes 212 are arranged far away from the water outlet 213. This design can limit the water output from the inner side of the electrode assembly 22 to gradually converge towards the area where the water passing holes 212 are located, and then pass through the water passing holes 212, the water outlet channel 211 and the water outlet 213 in sequence. During the flow of the water body, since the water passing holes 212 are arranged far away from the water outlet 213, the flowing water body will gradually converge towards the area where the water passing holes 212 are located, which will gradually squeeze the bubbles generated in the electrode assembly 22 to the area where the water passing holes 212 are located, then enter the water outlet channel 211 through the water passing holes 212, and be discharged together with the water body, thereby effectively removing the bubbles appearing in the capacitive deionization filter element 2.

[0094] As can be seen from the above, the water purification assembly shown in the present utility model can effectively discharge the bubbles generated in the filter element during the desalination process of the capacitive deionization filter element 2, prevent the capacitive deionization filter element 2 from generating noise during operation, ensure the stability of the internal electric field of the electrode assembly 22, and thus also ensure the water purification treatment effect of the capacitive deionization filter element 2.

[0095] It should be noted here that, as Figure 4 shown, the capacitive deionization filter element 2 further includes a protective sleeve. For example, the protective sleeve is a cylindrical rubber film. The protective sleeve is sleeved on the peripheral wall of the electrode assembly 22, and a plurality of water passing ports are formed on the protective sleeve to ensure that the water body can reach the outside of the electrode assembly 22 through the water passing ports, and then the electrode assembly 22 performs desalination treatment on the received water body.

[0096] In some embodiments, as Figure 2 、 Figure 5 and Figure 6 shown, a diversion groove 214 is provided on the peripheral wall of the water outlet pipe 21, and a fluid communication is formed between the diversion groove 214 and the water passing holes 212.

[0097] It can be understood that by providing the diversion groove 214 on the peripheral wall of the water outlet pipe 21, it is possible to avoid excessive restriction of the water body due to too small a gap between the inner side of the electrode assembly 22 and the peripheral wall of the water outlet pipe 21, so as to facilitate collecting the purified water output from the inner side of the electrode assembly 22 by means of the diversion groove 214 and then diverting the collected purified water to the water passing holes 212.

[0098] Among them, the depth of the diversion groove 214 can be set to 2 - 5 mm.

[0099] In some embodiments, as Figure 5 shown, since the length of the water outlet pipe 21 is substantially the same as the axial length of the electrode assembly 22 along the central axis, one end of the diversion groove 214 is provided on the peripheral wall near the first end of the water outlet pipe 21, and the other end is provided on the peripheral wall near the second end of the water outlet pipe 21. The purified water output from the inside of the electrode assembly 22 can be effectively collected at various positions along the axial direction of the water outlet pipe 21 by the diversion groove 214, ensuring the diversion effect on the purified water.

[0100] Among them, the diversion groove 214 can be configured to be provided on the peripheral wall of the water outlet pipe 21 along a spiral trajectory or along a straight trajectory, and no specific limitation is made thereto.

[0101] In some embodiments, as Figure 5 shown, the diversion groove 214 is configured to extend along the axial direction of the water outlet pipe 21. This design can effectively reduce the diversion path of the purified water and is also convenient for processing the diversion groove 214.

[0102] Meanwhile, since the inner and outer ends of the electrode assembly 22 relative to the water outlet pipe 21 are correspondingly formed as the water outlet end and the water inlet end, and the electrode assembly 22 is configured to be wound around the peripheral wall of the water outlet pipe 21, the water outlet end of the electrode assembly 22 extends along the axial direction of the water outlet pipe 21. By setting the diversion groove 214 to extend along the axial direction of the water outlet pipe 21, it is convenient to relatively arrange the diversion groove 214 with the water outlet end of the electrode assembly 22, ensuring the diversion effect on the purified water.

[0103] In some embodiments, as Figure 6 shown, in order to enhance the diversion effect on the purified water, a plurality of diversion grooves 214 and water passing holes 212 are provided. The plurality of diversion grooves 214 and the plurality of water passing holes 212 are relatively arranged, and at least part of the plurality of water passing holes 212 are arranged along the circumferential direction of the water outlet pipe 21.

[0104] Optionally, each diversion groove 214 can be configured to form a fluid communication with a plurality of water passing holes 212 arranged along the axial direction of the water outlet pipe 21, and each diversion groove 214 extends along the axial direction of the water outlet pipe 21.

[0105] Optionally, the plurality of diversion grooves 214 and the plurality of water passing holes 212 are arranged in a one-to-one correspondence. The plurality of water passing holes 212 are arranged along the circumferential direction of the water outlet pipe 21, and the plurality of diversion grooves 214 are also arranged along the circumferential direction of the water outlet pipe 21. Each diversion groove 214 extends along the axial direction of the water outlet pipe 21.

[0106] In some embodiments, a plurality of water passing holes 212 are provided, and the sum of the water passing areas of the plurality of water passing holes 212 is not less than 20 mm 2 , for example, the sum of the water passing areas of the plurality of water passing holes 212 is 20 mm 2, 25 mm 2 , 35 mm 2 and 50 mm 2 etc. This design avoids a large flow resistance when water passes through the water passing hole 212, preventing the water passing hole 212 from restricting the flow of water.

[0107] In some embodiments, to ensure the exhaust effect of the capacitive deionization filter element 2, the ratio of the axial distance between the water passing hole 212 and the second end of the water outlet pipe 21 to the length of the water outlet pipe 21 is not greater than 15%.

[0108] Optionally, the length of the capacitive deionization filter element 2 is approximately 333 - 350 mm. The axial distance between the water passing hole 212 and the second end of the water outlet pipe 21 can be set to be less than 50 mm, so that the water passing hole 212 is as far away as possible from the water outlet 213 of the capacitive deionization filter element 2, thereby ensuring the exhaust effect.

[0109] In some embodiments, such as Figure 7 , Figure 13 and Figure 14 shown, the electrode assembly 22 includes: an insulating sheet 221 and at least two layers of electrode sheets 222. The insulating sheet 221 and the electrode sheets 222 are arranged in a laminated manner, and the insulating sheet 221 is sandwiched between two adjacent layers of electrode sheets 222;

[0110] The electrode sheet 222 includes a current collector layer 2221 and an adsorption layer 2222. Adsorption layers 2222 are provided on both the front and back sides of the current collector layer 2221; Two adjacent electrode sheets 222 are respectively configured as a positive electrode sheet and a negative electrode sheet, and a water passing channel 2201 for accommodating the insulating sheet 221 is formed between the positive electrode sheet and the negative electrode sheet;

[0111] The inner and outer ends of the electrode assembly 22 corresponding to the water outlet pipe 21 are respectively formed as a water outlet end and a water inlet end; The water inlet end is communicated with the water outlet end through the water passing channel 2201. The water outlet end extends towards the peripheral wall of the water outlet pipe 21 and forms a fluid communication with the water passing hole 212.

[0112] It is understandable that the insulating sheet 221 and the electrode sheet 222 are stacked in an alternating arrangement manner, so that the insulating sheet 221 is clamped between two adjacent layers of electrode sheets 222. Since two adjacent layers of electrode sheets 222 are respectively configured as a positive electrode sheet and a negative electrode sheet, when the number of electrode sheets 222 is greater than two layers, in order to meet the water filtration requirement of the electrode assembly 22 for raw water, when designing the power supply for the electrode assembly 22, the positive electrode sheet and the negative electrode sheet can be arranged alternately in sequence along the stacking direction, the insulating sheet 221 is clamped between the positive electrode sheet and the negative electrode sheet, and the current collector layer 2221 of the positive electrode sheet is electrically connected to the positive electrode of the power supply, and the current collector layer 2221 of the negative electrode sheet is electrically connected to the negative electrode of the power supply. When the number of electrode sheets 222 is equal to two layers, the insulating sheet 221 can be directly clamped between the positive electrode sheet and the negative electrode sheet.

[0113] For the electrode sheet 222, the current collector layer 2221 of the electrode sheet 222 can be made of metal or graphite material, so that the current collector layer 2221 is formed as a conductive layer, and the adsorption layer 2222 of the electrode sheet 222 can be made of activated carbon and other adsorption materials to adsorb ions in the raw water.

[0114] At the same time, the insulating sheet 221 can be made of plastic material. The insulating sheet 221 is used to play a supporting role between the positive electrode sheet and the negative electrode sheet, which not only prevents the short-circuit connection between the positive electrode sheet and the negative electrode sheet, but also ensures the formation of a water passage 2201 between the positive electrode sheet and the negative electrode sheet.

[0115] In practical applications, the operation of the capacitive deionization filter element 2 includes an adsorption purification process and a desorption regeneration process. When two adjacent layers of electrode sheets 222 are electrically connected to the positive and negative electrodes of the power supply and the power supply is started to supply power, the cations and anions in the raw water are attracted to the electrode sheets 222 with opposite charges and are adsorbed by the adsorption layer 2222 on the electrode sheets 222. This operation process of the capacitive deionization filter element 2 is the adsorption purification process.

[0116] Correspondingly, when the power supply is stopped or a reverse voltage is applied to two adjacent layers of electrode sheets 222, the ions adsorbed by the adsorption layer 2222 are detached into the water body of the water passage 2201. At this time, the water passage 2201 will output concentrated water with a higher ion concentration.

[0117] As can be seen from the above, the capacitive deionization filter element 2 shown in this embodiment realizes the integrated design of the electrode sheet 222 by arranging the adsorption layer 2222 on the front and back sides of the current collector layer 2221. Only by stacking the electrode sheet 222 and the insulating sheet 221 in an alternating arrangement manner can the electrode assembly 22 be formed; this stacked arrangement design of the electrode assembly 22 simplifies the arrangement structure of the electrode assembly 22, is convenient for processing and production, and is beneficial to reducing production costs.

[0118] Meanwhile, in practical applications, it is only necessary to electrically connect the adjacent two layers of electrode sheets 222 to the positive and negative electrodes of the power supply, so as to adsorb the ions in the raw water passing through the water passage 2201, achieving the purpose of purifying the raw water; since the adsorption layers 2222 are provided on both sides of the current collector layer 2221 of each electrode sheet 222, the two sides of each electrode sheet 222 can adsorb ions, thus ensuring the purification effect of the raw water to a certain extent. The capacitive deionization filter element 2 can effectively remove heavy metal ions in water and retain beneficial ions required by the human body, meeting the needs of household water purification.

[0119] In some embodiments, in order to ensure the purification effect of the raw water, the adjacent two layers of electrode sheets 222 are arranged oppositely along the stacking direction to ensure the coverage range of the electric field between the adjacent two layers of electrode sheets 222 as much as possible, and then remove anions, cations and other charged particles in the raw water based on the electric field between the adjacent two layers of electrode sheets 222.

[0120] Furthermore, by arranging the insulating sheet 221 and the electrode sheet 222 to be misaligned along the stacking direction, the electrode sheet 222 is hidden between the adjacent two layers of insulating sheets 221. This design not only ensures the electrical isolation between the adjacent two layers of electrode sheets 222, but also facilitates setting the water outlet end of the electrode assembly 22 at a position opposite to the water passing holes 212 and / or the diversion grooves 214 on the peripheral wall of the water outlet pipe 21 to ensure the fluid communication between the water passage 2201 in the electrode assembly 22 and the water outlet passage 211 in the water outlet pipe 21. Wherein, the stacking direction is along the thickness direction of the insulating sheet 221 or the electrode sheet 222.

[0121] In some embodiments, multiple groups of water passing holes 212 are arranged along the circumferential direction of the peripheral wall of the water outlet pipe 21. For example, multiple groups of water passing holes 212 are evenly arranged along the circumferential direction of the water outlet pipe 21; each group of water passing holes 212 is arranged along the axial direction of the water outlet pipe 21; the number of electrode sheets 222 is greater than two, so that the electrode assembly 22 forms multiple water passages 2201, the inner ends of the electrode assembly 22 form multiple water outlet ends corresponding to the multiple water passages 2201, and the multiple water outlet ends are arranged opposite to the multiple groups of water passing holes 212.

[0122] It can be understood that by setting the number of electrode sheets 222 to be greater than two, based on the multiple water passages 2201 formed by the electrode assembly 22, the raw water flowing in multiple paths in the capacitive deionization filter element 2 can be purified simultaneously, improving the purification efficiency of the raw water.

[0123] Meanwhile, by arranging multiple water outlet ends opposite to multiple groups of water passing holes 212, the smoothness of the water path between each water passage 2201 and the water outlet passage 211 in the water outlet pipe 21 can be ensured, which is beneficial to ensuring the water purification and outlet flow rate of the capacitive deionization filter element 2.

[0124] In some embodiments, such as Figure 2 , Figure 4 and Figure 7 shown, to facilitate the connection of two adjacent electrode sheets 222 to the positive and negative electrodes of the power supply, the electrode assembly 22 further includes: a positive electrode tab 201 and a negative electrode tab 202; the positive electrode tab 201 is electrically connected to the current collector layer 2221 of the positive electrode sheet; the negative electrode tab 202 is electrically connected to the current collector layer 2221 of the negative electrode sheet.

[0125] Specifically, a first extension portion is provided on one side edge of the current collector layer 2221 of each positive electrode sheet, and a second extension portion is provided on one side edge of the current collector layer 2221 of each negative electrode sheet; when the electrode assembly 22 is wound around the peripheral wall of the water outlet pipe 21, the first extension portions of the respective positive electrode sheets are stacked to form the positive electrode tab 201, and the second extension portions of the respective negative electrode sheets are stacked to form the negative electrode tab 202.

[0126] In some embodiments, the current collector layer 2221 includes any one of copper foil, titanium foil, and graphite paper, and the current collector layer 2221 is configured to be electrically connected to the positive or negative electrode of the power supply.

[0127] The adsorption layer 2222 adheres to the surface of the current collector layer 2221. The adsorption layer 2222 includes an activated carbon layer, and the activated carbon layer has excellent adsorption performance and can adsorb ions in raw water.

[0128] In some embodiments, since the thickness of the current collector layer 2221 of the electrode sheet 222 determines the support strength, winding difficulty, and cost of the electrode sheet 222, if the current collector layer 2221 is too thin, the current collector layer 2221 is easily damaged. If the current collector layer 2221 is too thick, the cost of the electrode sheet 222 is too high. Therefore, the thickness of the current collector layer 2221 is set to 15 - 50 microns; optionally, the thickness of the current collector layer 2221 is specifically 25 microns, 30 microns, 35 microns, 40 microns, 45 microns, 50 microns, etc.

[0129] At the same time, since the thickness of the adsorption layer 2222 of the electrode sheet 222 determines the adsorption capacity and adsorption speed, however, if the adsorption layer 2222 is too thick, the adsorption layer 2222 will crack during winding. Therefore, the thickness of the adsorption layer 2222 is set to 25 - 200 microns; optionally, the thickness of the adsorption layer 2222 is specifically 25 microns, 30 microns, 50 microns, 65 microns, 100 microns, 150 microns, 185 microns, 200 microns, etc.

[0130] In some embodiments, the insulating sheet 221 can be configured as a porous structure. For example, the insulating sheet 221 includes insulating fabric or insulating grid. The insulating fabric can be woven fabric or melt - blown fabric.

[0131] Thus, although the insulating sheet 221 is disposed in the water passage 2201, since the insulating sheet 221 has a porous structure, the insulating sheet 221 does not affect the migration of ions between two adjacent electrode sheets 222, and thus does not affect the adsorption of ions in the water body by the adsorption layer 2222 of the electrode sheet 222. The insulating sheet 221 ensures the uniform flow of water in the water passage 2201, and can ensure the adsorption effect of the adsorption layer 2222 on ions to a certain extent.

[0132] In some embodiments, considering that the greater the thickness of the insulating sheet 221, the smaller the water flow pressure loss and the lower the blockage risk. However, the greater the thickness of the insulating sheet 221, the greater the distance between two adjacent electrode sheets 222, and thus the greater the resistance between two adjacent electrode sheets 222, resulting in poorer water purification performance. Therefore, in order to comprehensively consider the pressure loss and water purification effect, the thickness of the insulating sheet 221 is set to 0.1-1.0 mm; optionally, the thickness of the insulating sheet 221 is specifically set to 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc.

[0133] In an alternative embodiment, as Figure 3 shown, one end of the water outlet pipe 21 provided with the water outlet 213 extends into the water outlet space 111, and the outer side surface of the water outlet pipe 21 is sealingly connected to the inner wall of the water outlet space 111.

[0134] In other words, one end of the water outlet pipe 21 provided with the water outlet 213 extends into the first partition plate 121, and the outer side surface of the water outlet pipe 21 is sealingly connected to the inner side surface of the first partition plate 121. For example, the sealing connection is achieved through a sealing ring.

[0135] In a second aspect, an embodiment of the present invention further provides a water purification device, including: a body and the water purification component as above; the body has an installation cavity, and the water purification component is detachably disposed in the installation cavity.

[0136] Specifically, the water purification device may be an instant hot water dispenser, and the body may be provided with an installation port communicating with the installation cavity, and the capacitive deionization filter element 2 may be inserted into the installation cavity through the installation port.

[0137] Since the water purification device includes the water purification component, and the specific structure of the water purification component refers to the above embodiments, the water purification device of this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiments, which will not be repeated here one by one.

[0138] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
