[0002] Capacitive Deionization (CDI) is a water desalination and purification technology based on the double-layer capacitance theory. Its basic principle is that after applying a low voltage to the electrodes, cations, anions or charged particles in the solution migrate to the two electrodes respectively under the action of the electric field force and the concentration gradient, and adsorb on the electrode surface to form a double-layer capacitance, so as to achieve the purpose of desalination or purification. The capacitive deionization technology can achieve different water outlet qualities at different voltages, while retaining the ions beneficial to the human body and removing heavy metal ions.

[0054] The following will Figures 1 to 14 , through specific embodiments and their application scenarios, elaborate in detail on the water purification components and water purification equipment provided by the embodiments of the present utility model.

[0055] As Figure 2 and Figure 3 shown, the water purification component of the embodiment of the present utility model includes: a housing 1 and a capacitive deionization filter element 2.

[0056] The capacitive deionization filter element 2 is arranged inside the housing 1. The capacitive deionization filter element 2 has a water inlet end in its radial direction and a water outlet 212 in its axial direction;

[0057] Among them, the housing 1 includes a connected first housing 11 and a second housing 12. The first housing 11 is provided with a first insertion hole 103 and a second insertion hole 104. The first end of the capacitive deionization filter element 2 has a positive electrode conductor and a negative electrode conductor. The positive electrode conductor and the negative electrode conductor are located inside the first housing 11. At least part of the positive electrode conductor is exposed outside the first insertion hole 103, and at least part of the negative electrode conductor is exposed outside the second insertion hole 104. The outer side surface of the capacitive deionization filter element 2 is hermetically connected to the inner wall of the second housing 12 near its first end. A first gap is left between the outer side surface of the capacitive deionization filter element 2 and the inner wall of the second housing 12. The second housing 12 is provided with a water outlet port 102 and a water inlet port 101 communicating with the first gap. The water outlet 212 at the second end of the capacitive deionization filter element 2 is communicated with the water outlet port 102.

[0058] It should be particularly noted that the first housing 11 and the second housing 12 can be connected by rotational welding and threaded connection, and after the first housing 11 and the second housing 12 are assembled, the positive electrode conductor does not enter the first insertion hole 103, and the negative electrode conductor does not enter the second insertion hole 104.

[0059] It can be understood that the housing 1 is columnar, and an accommodation cavity is provided inside the housing 1. The capacitive deionization filter element 2 is installed in the accommodation cavity and is configured to be coaxially arranged with the housing 1.

[0060] It should be noted that the first shell 11 has a first plug hole 103 and a second plug hole 104, and the second shell 12 has a water inlet port 101 and a water outlet port 102, that is, the first plug hole 103 and the second plug hole 104 are located on one side of the shell 1, and the water inlet port 101 and the water outlet port 102 are located on the other side of the shell 1.

[0061] In addition, the outer side surface of the capacitor deionizing filter element 2 is sealed and connected to the inner wall of the second shell 12 near its first end, so that the isolation between the first plug hole 103 and the second plug hole 104 and the water inlet port 101 and the water outlet port 102 can be ensured, and the water entering the second shell 12 from the water inlet port 101 cannot enter the first shell 11.

[0062] When the capacitor deionizing filter element 2 is assembled to the housing 1, the capacitor deionizing filter element 2 is first assembled with the second housing 12 so that the water outlet 212 at the second end of the capacitor deionizing filter element 2 is connected to the water outlet port 102 at the second housing 12. Thereafter, the first housing 11 is docked with the second housing 12 so that at least part of the positive conductor at the first end of the capacitor deionizing filter element 2 is exposed to the first plug hole 103, and at least part of the negative conductor is exposed to the second plug hole 104. After the positive conductor is docked with the first plug hole 103 and the negative conductor is docked with the second plug hole 104, the connection between the first housing 11 and the second housing 12 is completed. In this way, by setting the housing 1 as the first housing 11 and the second housing 12, the docking accuracy between the positive conductor and the first plug hole 103 and the docking accuracy between the negative conductor and the second plug hole 104 can be ensured.

[0063] In some embodiments, Figure 2 , Figure 3 and Figure 9 As shown, the capacitor deionizing filter element 2 includes a first end cap 3 and a core body 20, the first end cap 3 includes a side wall 31 and a top wall 32 connected to each other, the side wall 31 is connected to the inner wall of the shell 1, the top wall 32 is connected to the first end of the core body 20, and the top wall 32, the side wall 31 and the inner wall of the first shell 11 enclose a accommodating space 112; the top wall 32 is provided with a first through hole 322 for the positive conductor to pass through and a second through hole for the negative conductor to pass through.

[0064] It can be understood that the top wall 32 is disc-shaped, and the side wall 31 is extended circumferentially relative to the central axis of the core 20; the side wall 31 is arranged on the side of the top wall 32 away from the core 20, and abuts against the inner wall of the first end of the first shell 11, so that the top wall 32, the side wall 31 and the inner wall of the first shell 11 enclose a containing space 112.

[0065] likeFigure 2 , Figure 3 and Figure 9 As shown in Figure 2 , Figure 3 and Figure 9 , the first end cap 3 further includes: a first rubber blocking wall 33 bent and connected to the top wall 32. The outer side surface of the first rubber blocking wall 33 is sealingly connected to the inner wall of the second housing 12. The top wall 32 and the first end of the core 20 are sealingly connected through a filling rubber. The inner side surface of the first rubber blocking wall 33 is attached to the outer side surface of the core 20.

[0066] It can be understood that the filling rubber forms a sealing rubber layer at the first end of the core 20, and the top wall 32 is attached to the surface of the sealing rubber layer to achieve the sealing of the first end of the core 20.

[0067] The first rubber blocking wall 33 is provided at the outer edge of the top wall 32 and extends circumferentially relative to the center of the top wall 32. The inner diameter of the first rubber blocking wall 33 is adapted to the diameter of the core 20. The first rubber blocking wall 33 is used to prevent the filling rubber from overflowing to the peripheral wall of the core 20.

[0068] A first support rib can be provided on the side surface of the top wall 32 facing the core 20. The first support rib can be configured to extend radially along the core 20. The first support rib is used to ensure the thickness of the filling rubber filled at the first end of the core 20 and is beneficial to ensuring the molding quality of the filling rubber.

[0069] Wherein, by setting the outer side surface of the first rubber blocking wall 33 to be sealingly connected to the inner wall of the second housing 12, water can be prevented from entering the accommodation space 112 formed by enclosing between the top wall 32, the side wall 31 and the inner wall of the first housing 11.

[0070] In some embodiments, as Figure 2 shown, in order to ensure the molding quality of the filling rubber, the first end cap 3 further includes a rubber blocking plate 321. The rubber blocking plate 321 is arranged on the side of the top wall 32 facing the first end of the core 20 and is arranged close to the outer side surface of the core 20.

[0071] That is to say, the annular rubber blocking plate 321 is arranged inside the top wall 32. The annular rubber blocking plate 321 is coaxially arranged with the first rubber blocking wall 33, and the rubber blocking plate 321 is spaced from the first rubber blocking wall 33. The rubber blocking plate 321 is used to limit the flow of the filling rubber towards the area where the through hole is located.

[0072] In some embodiments, as Figure 9 shown, the projected area of the first through hole 322 on the first end of the core 20 is larger than the projected area of the positive electrode tab 201 on the first end of the core 20, and the projected area of the second through hole on the first end of the core 20 is larger than the projected area of the negative electrode tab 202 on the first end of the core 20.

[0073] Thus, it is convenient to seal the positive electrode conductor and the negative electrode conductor at the first end of the core 20. That is to say, after sealing the area between the rubber baffle 321 and the first rubber baffle wall 33 at the first end of the core 20, the remaining area (the area enclosed by the rubber baffle 321) at the first end of the core 20 is sealed through the first through hole 322 and the second through hole.

[0074] In an alternative embodiment, as Figure 9 and Figure 13 shown, the capacitive deionization filter element 2 further includes a fixing seat 6. The annular fixing seat 6 is provided with a first positioning hole 62 adapted to the positive electrode conductor and a second positioning hole adapted to the negative electrode conductor. The fixing seat 6 is detachably arranged on the side wall 31. The positive electrode conductor sequentially passes through the first positioning hole 62 and the first through hole 322, and the negative electrode conductor sequentially passes through the second positioning hole and the second through hole.

[0075] Thus, through the first positioning hole 62 and the second positioning hole, the coaxiality of the positive electrode conductor and the negative electrode conductor can be ensured, and further the docking progress of the positive electrode conductor and the first through hole 322 and the docking progress of the negative electrode conductor and the second through hole can be improved.

[0076] In some embodiments, as Figure 9 and Figure 13 shown, in order to improve the installation stability of the fixing seat 6 and the first end cover 3, a clamping groove 61 is provided on one side of the fixing seat 6 facing the top wall 32, and a clamping buckle 311 is provided on the inner side surface of the side wall 31. The fixing seat 6 and the first end cover 3 are in limit fit in the circumferential direction through the clamping groove 61 and the clamping buckle 311.

[0077] In an alternative embodiment, each of the positive electrode conductor and the negative electrode conductor includes an electrical connection member and a tab connected to the core 20. The tab is detachably and electrically connected to the electrical connection member, and the electrical connection member sequentially passes through the corresponding positioning hole.

[0078] Specifically, the power connection assembly 5 includes a positive electrode electrical connection member 51 and a negative electrode electrical connection member 52. The core 20 is provided with a positive electrode tab 201 and a negative electrode tab 202. The positive electrode electrical connection member 51 is electrically connected to the positive electrode tab 201, and the positive electrode electrical connection member 51 can pass through the first positioning hole 62. The negative electrode electrical connection member 52 is electrically connected to the negative electrode tab 202, and the negative electrode electrical connection member 52 can pass through the second positioning hole.

[0079] In some embodiments, each of the first positioning hole 62 and the second positioning hole is a stepped hole. The stepped hole is provided with a stepped surface, and an abutting surface is provided on the outer side surface of each electrical connection member. The abutting surface abuts against the stepped surface.

[0080] That is to say, under the action of the fixed seat 6, the butt coaxiality between the electrical connector and the tab can be ensured, and during the butt joint process of the electrical connector and the tab, the electrical connector will not move excessively, so as to avoid extrusion damage to the tab.

[0081] In some embodiments, each of the positive electrical connector 51 and the negative electrical connector 52 is provided with a slot, and the corresponding tab is inserted into the slot. For example, the bottom of the positive electrical connector 51 is provided with a slot, and the positive tab 201 can be inserted into the slot of the positive electrical connector 51. In this way, the quick and stable butt joint between the electrical connector and the tab can be ensured.

[0082] In an alternative embodiment, the core 20 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. Both ends of the electrode assembly 22 along the axial direction of the water outlet pipe 21 are sealed. The outside of the electrode assembly 22 is for receiving the input of raw water, and the inside of the electrode assembly 22 is for outputting purified water or wastewater.

[0083] The water outlet pipe 21 has a water outlet channel, a first water passing hole 211 and a water outlet 212 communicated with the water outlet channel. The water outlet channel is arranged inside the water outlet pipe 21, the water outlet channel forms the water outlet 212, and the first water passing hole 211 is arranged on the peripheral wall of the water outlet pipe 21.

[0084] Furthermore, as Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 shown, the core 20 of the embodiment of the present invention includes a water outlet pipe 21, a diversion pipe 23 and an electrode assembly 22. The electrode assembly 22 is wound around the peripheral wall of the water outlet pipe 21. Both ends of the electrode assembly 22 along the axial direction of the water outlet pipe 21 are sealed. The outside of the electrode assembly 22 is for receiving the input of raw water, and the inside of the electrode assembly 22 is for outputting purified water or wastewater.

[0085] The peripheral wall of the water outlet pipe 21 is provided with the first water passing hole 211. The first end of the water outlet pipe 21 forms the water outlet 212, and the second end of the water outlet pipe 21 is closed. The diversion pipe 23 is inserted into the water outlet pipe 21 to form a water passing gap 201 between the diversion pipe 23 and the water outlet pipe 21. The peripheral wall of the first end of the diversion pipe 23 is hermetically connected to the inner wall of the water outlet pipe 21, and a second water passing hole 202 is formed between the second end of the diversion pipe 23 and the second end of the water outlet pipe 21.

[0086] Wherein, the first water passing hole 211, the water passing gap 201, the second water passing hole 202, the inner cavity of the diversion pipe 23 and the water outlet 212 are sequentially in fluid communication. The outer diameter of the diversion pipe 23 is smaller than the inner diameter of the water outlet pipe 21 to form the water passing gap 201 between the diversion pipe 23 and the water outlet pipe 21.

[0087] It is understandable that the electrode assembly 22 generally includes a positive electrode plate and a negative electrode plate arranged in a stacked manner. The positive electrode plate and the negative electrode plate are isolated from each other, and a flow channel for the flow of the water body is formed between the positive electrode plate and the negative electrode plate. When winding the electrode assembly 22, the inner side surface of one end of the electrode assembly 22 contacts the peripheral wall of the water outlet pipe 21, and then, with the water outlet pipe 21 as the central axis, the electrode assembly 22 is wound layer by layer until the electrode assembly 22 is wound into a columnar distribution form.

[0088] Since the electrode assembly 22 is wound around the peripheral wall of the water outlet pipe 21 and the two ends of the electrode assembly 22 along the axial direction of the water outlet pipe 21 are sealed, when a positive voltage is applied to the positive electrode plate and the negative electrode plate, cations, anions or charged particles in the water body will migrate to the surfaces of the positive electrode plate and the negative electrode plate under the action of the electric field force, so that purified water after desalination treatment is output from the inner side of the electrode assembly 22; when a reverse voltage is applied to the positive electrode plate and the negative electrode plate, or when the voltage applied to the positive electrode plate and the negative electrode plate is stopped, the anions, cations or charged particles adsorbed on the surfaces of the positive electrode plate and the negative electrode plate will automatically detach, so that wastewater with a higher concentration is output from the inner side of the electrode assembly 22.

[0089] Considering that the peripheral wall of the existing water outlet pipe 21 is usually densely provided with a plurality of water passing holes, the water body output from the inner side of the electrode assembly 22 will uniformly pass through each water passing hole and enter the water outlet channel. If air bubbles appear in the electrode assembly 22, the air 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 air bubbles. However, in the present application, a diversion pipe 23 is arranged in the water outlet pipe 21, and a second water passing hole 202 is arranged between the second end of the diversion pipe 23 and the second end of the water outlet pipe 21, so that the second water passing hole 202 is arranged far away from the water outlet 212. This design can limit the water body output from the inner side of the electrode assembly 22 to gradually converge towards the area where the second water passing hole 202 is located after entering the water passing gap 201 from the first water passing hole 211, then enter the diversion pipe 23 through the second water passing hole 202, and finally be output from the water outlet 212 under the guidance of the diversion pipe 23. Then, during the flow of the water body, since the second water passing hole 202 is arranged far away from the water outlet 212, the flowing water body gradually converges towards the area where the second water passing hole 202 is located, which will gradually squeeze the air bubbles generated in the electrode assembly 22 to the area where the second water passing hole 202 is located, and then be discharged together with the water body under the guidance of the diversion pipe 23, thereby effectively removing the air bubbles appearing in the core 20.

[0090] As can be seen from the above, for the water purification assembly shown in the present utility model, during the desalination process of the core 20, it can effectively discharge the air bubbles generated in the filter element, prevent the core 20 from generating noise during operation, ensure the stability of the internal electric field of the electrode assembly 22, and thus ensure the water purification treatment effect of the core 20.

[0091] It should be noted here that the core body 20 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. A plurality of water passing holes are formed in the protective sleeve to ensure that water can reach the outside of the electrode assembly 22 through the water passing holes, and then the electrode assembly 22 desalinates the received water body.

[0092] In some embodiments, as Figure 6 and Figure 7 shown, a blocking member 230 is provided in the water outlet pipe 21. The blocking member 230 is provided at a position close to the second end of the water outlet pipe 21; the peripheral wall of the first end of the diversion pipe 23 is hermetically connected to the inner wall of the first end of the water outlet pipe 21, and a second water passing hole 202 is formed between the second end of the diversion pipe 23 and the blocking member 230.

[0093] It can be understood that the axial distance between the blocking member 230 and the second end of the water outlet pipe 21 is less than the axial distance between the blocking member 230 and the first end of the water outlet pipe 21.

[0094] The length of the diversion pipe 23 can be configured to be equal to the axial length between the blocking member 230 and the first end of the water outlet pipe 21. A sealing ring can be used to achieve the sealing connection between the peripheral wall of the first end of the diversion pipe 23 and the inner wall of the first end of the water outlet pipe 21. The second end of the diversion pipe 23 can be configured to abut against the blocking member 230. However, a gap is reserved between the second end of the diversion pipe 23 and the blocking member 230 to form the above-mentioned second water passing hole 202.

[0095] Furthermore, as Figure 7 shown, the blocking member 230 includes: a blocking plate 2301 and a plurality of protrusions 2302; the blocking plate 2301 is connected to the inner wall of the water outlet pipe 21. For example, the periphery of the blocking plate 2301 is connected to the inner wall of the water outlet pipe 21; the plurality of protrusions 2302 are provided on the side of the blocking plate 2301 facing the water outlet 212. The plurality of protrusions 2302 are arranged at intervals in the circumferential direction. The second end of the diversion pipe 23 abuts against at least part of the plurality of protrusions 2302, and a second water passing hole 202 is formed between two adjacent protrusions 2302.

[0096] It can be understood that since the plurality of protrusions 2302 are arranged at intervals in the circumferential direction, a plurality of second water passing holes 202 are provided. The plurality of second water passing holes 202 are defined to be arranged in the circumferential direction, and each second water passing hole 202 can achieve the fluid communication between the water passing gap 201 and the inner cavity of the diversion pipe 23.

[0097] In some embodiments, in order to ensure the exhaust effect of the core body 20, the ratio of the axial distance between the blocking member 230 and the second end of the water outlet pipe 21 to the length of the water outlet pipe 21 is not greater than 15%.

[0098] It is understandable that since a second water passing hole 202 is formed between the second end of the diversion pipe 23 and the plugging member 230, the proportion of the axial length between the second water passing hole 202 and the water outlet 212 to the length of the water outlet pipe 21 is not greater than 15%.

[0099] Optionally, the length of the core body 20 is approximately 333 - 350 mm, and the axial distance between the plugging member 230 and the second end of the water outlet pipe 21 can be set to be less than 50 mm, so that the second water passing hole 202 is as far away from the water outlet 212 of the core body 20 as possible, thereby ensuring the exhaust effect.

[0100] In some embodiments, there are multiple second water passing holes 202, and the sum of the water passing areas of the multiple second water passing holes 202 is not less than 20 mm². For example, the sum of the water passing areas of the multiple second water passing holes 202 is 200 mm², 250 mm², 350 mm², 500 mm², etc. This design avoids a large flow resistance when the water body passes through the second water passing hole 202 and prevents the second water passing hole 202 from restricting the flow of the water body.

[0101] In some embodiments, such as Figure 8 、 Figure 10 and Figure 12 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 clamped between two adjacent layers of electrode sheets 222;

[0102] 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;

[0103] The inner and outer ends of the electrode assembly 22 relative 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, and the water outlet end extends towards the peripheral wall of the water outlet pipe 21 and forms a fluid communication with the first water passing hole 211.

[0104] It is understandable that the insulating sheet 221 and the electrode sheet 222 are stacked in an alternating arrangement, so that the insulating sheet 221 is clamped between adjacent two layers of electrode sheets 222. Since adjacent two 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.

[0105] 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.

[0106] 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.

[0107] In practical applications, the operation of the core 20 includes an adsorption purification process and a desorption regeneration process. When adjacent two 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 core 20 is the adsorption purification process.

[0108] Correspondingly, when the power supply is stopped, or when a reverse voltage is applied to adjacent two 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.

[0109] As can be seen from the above, for the core 20 shown in this embodiment, by arranging the adsorption layer 2222 on the front and back sides of the current collector layer 2221, the integrated design of the electrode sheet 222 is realized. The electrode sheet 222 and the insulating sheet 221 are stacked in an alternating arrangement, and the electrode assembly 22 can 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.

[0110] Meanwhile, in practical applications, only by electrically connecting the adjacent two layers of electrode sheets 222 to the positive and negative electrodes of the power supply, the ions in the raw water passing through the water passage 2201 can be adsorbed, so as to achieve the purpose of purifying the raw water; since the adsorption layers 2222 are provided on both side surfaces of the current collector layer 2221 of each electrode sheet 222, the two side surfaces of each electrode sheet 222 can adsorb ions, thus ensuring the purification effect of the raw water to a certain extent. The core body 20 can effectively remove heavy metal ions in water and retain beneficial ions required by the human body, meeting the needs of household water purification.

[0111] In some embodiments, to ensure the purification effect of the raw water, the adjacent two layers of electrode sheets 222 are arranged oppositely along the stacking direction, so as 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.

[0112] Furthermore, by arranging the insulating sheet 221 and the electrode sheet 222 in a staggered manner along the stacking direction, the electrode sheet 222 can be 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 first water passage hole 211 on the peripheral wall of the water outlet pipe 21, so as to ensure the fluid communication between the water passage 2201 in the electrode assembly 22 and the water passage gap 201 inside the water outlet pipe 21.

[0113] Among them, as Figure 11 shown, the stacking direction is along the thickness direction of the insulating sheet 221 or the electrode sheet 222.

[0114] In some embodiments, as Figure 6 and Figure 8 shown, a plurality of groups of first water passage holes 211 are arranged along the circumferential direction on the peripheral wall of the water outlet pipe 21, and each group of first water passage holes 211 is arranged along the axial direction of the water outlet pipe 21;

[0115] The number of the electrode sheets 222 is greater than two, so that the electrode assembly 22 forms a plurality of water passages 2201; the inner ends of the electrode assembly 22 form a plurality of water outlet ends corresponding to the plurality of water passages 2201, and the plurality of water outlet ends are arranged opposite to the plurality of groups of first water passage holes 211.

[0116] It can be understood that by setting the number of the electrode sheets 222 to be greater than two, based on the plurality of water passages 2201 formed by the electrode assembly 22, the raw water flowing in multiple paths in the core body 20 can be purified simultaneously, improving the purification efficiency of the raw water.

[0117] Meanwhile, by providing a plurality of water outlets opposite to a plurality of groups of first water passing holes 211, the smoothness of the water path between each water passing channel 2201 and the water passing gap 201 inside the water outlet pipe 21 can be ensured, which is conducive to ensuring the purified water outlet flow rate of the core 20.

[0118] In practical applications, while ensuring electrical isolation between adjacent two electrode sheets 222, along the extending direction of the electrode sheet 222, the insulating sheet 221 at one end of the electrode assembly 22 close to the water outlet pipe 21 and the end portions of the electrode sheets 222 are arranged in a staggered manner in turn and are arranged circumferentially along the water outlet pipe 21.

[0119] In some embodiments, such as Figure 3 、 Figure 4 and Figure 8 shown, in order to facilitate connecting adjacent two 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.

[0120] 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 circumferential 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.

[0121] 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.

[0122] The adsorption layer 2222 adheres to the surface of the current collector layer 2221, and the adsorption layer 2222 includes an activated carbon layer, and the activated carbon layer has excellent adsorption performance and can adsorb ions in the raw water.

[0123] 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, and 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.

[0124] Meanwhile, 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.

[0125] 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 meltblown fabric.

[0126] Thus, although the insulating sheet 221 is disposed in the water passage 2201, however, since the insulating sheet 221 is a porous structure, the insulating sheet 221 will not affect the migration of ions between two adjacent electrode sheets 222, and thus will not affect the adsorption of ions in the water body by the adsorption layer 2222 of the electrode sheet 222. The insulating sheet 221 will ensure 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.

[0127] 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.

[0128] In an alternative embodiment, as Figure 3 shown, a partition 121 is provided on the inner wall of the second housing 12. One end of the water outlet pipe 21 provided with the water outlet 212 extends into the water outlet space 111 formed by the partition 121 and communicates with the water outlet port 102 through the water outlet space 111.

[0129] In other words, one end of the water outlet pipe 21 provided with the water outlet 212 extends into the partition 121, and the outer side surface of the water outlet pipe 21 is sealingly connected to the inner side surface of the partition 121. For example, the sealing connection is achieved through a sealing ring.

[0130] In some embodiments, as Figure 2 , Figure 3 and Figure 10As shown, the capacitive deionization filter element 2 further includes: a second end cap 4, the second end cap 4 includes a bottom wall 41 and a second rubber blocking wall 42 which are bent and connected. The bottom wall 41 is limited between the second end of the core body 20 and the side of the partition plate 121 away from the inner wall of the second housing 12. The bottom wall 41 is provided with a through hole, and the water outlet 212 passes through the through hole and communicates with the water outlet space 111;

[0131] The bottom wall 41 is hermetically connected to the second end of the core body 20 by filling glue. The second rubber blocking wall 42 fits against the peripheral wall of the core body 20. There is a second gap between the outer side surface of the second rubber blocking wall 42 and the inner wall of the second housing 12. The water inlet port 101 communicates with the first gap through the second gap.

[0132] It can be understood that the filling glue forms a sealing glue layer at the second end of the core body 20. The second rubber blocking wall 42 is arranged on the outer edge of the bottom wall 41 and extends circumferentially relative to the water outlet 212. The inner diameter of the second rubber blocking wall 42 is adapted to the diameter of the core body 20.

[0133] Multiple ribs can be arranged on the outer side surface of the second rubber blocking wall 42. The multiple ribs are arranged circumferentially along the second rubber blocking wall 42 and abut against the inner wall of the second housing 12, so as to form a second gap between the outer side surface of the second rubber blocking wall 42 and the inner wall of the second housing 12. Of course, multiple ribs can also be arranged on the inner wall of the second housing 12. The multiple ribs are arranged circumferentially relative to the axis where the water outlet 212 is located and abut against the outer side surface of the second rubber blocking wall 42. This design can also form a second gap between the outer side surface of the second rubber blocking wall 42 and the inner wall of the second housing 12.

[0134] Furthermore, in order to ensure the sealing effect of the second end of the core body 20, a second support rib is provided on the side surface of the bottom wall 41 facing the core body 20. The second support rib can be configured to extend radially along the core body 20. The second support rib is used to ensure the filling thickness of the filling glue at the second end of the core body 20 and is beneficial to ensuring the forming quality of the filling glue.

[0135] In practical applications, such as Figure 9 、 Figure 10 、 Figure 13 and Figure 14As shown in the figure, first, a layer of filling glue is set in the first area at the first end of the core body 20. The first area is the area between the first glue-blocking wall 33 and the glue-blocking plate 321. Then, the first end cap 3 is covered on the first end of the core body 20. Since the first glue-blocking wall 33 fits with the peripheral wall of the core body 20 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 core body 20, but also limit the core body 20 in the radial direction to ensure the coaxiality of the core body 20 and the water outlet port 102. Next, a layer of filling glue is set in the second area at the first end of the core body 20. The second area is the area enclosed by the glue-blocking plate 321, thus completing the sealing of the first end of the core body 20. Subsequently, the fixing seat 6 is installed on the side wall 31. Under the limiting cooperation of the card slot 61 and the buckle 311, the first positioning hole 62 can correspond to the positive electrode tab 201, and the second positioning hole can correspond to the negative electrode tab 202. After that, the positive electrode electrical connector 51 is installed in the first positioning hole 62 and completes the plug-in cooperation with the positive electrode tab 201, and the negative electrode electrical connector 52 is installed in the second positioning hole and completes the plug-in cooperation with the negative electrode tab 202. That is to say, under the action of the fixing seat 6, it can ensure the docking coaxiality of the electrical connector and the tab, and ensure 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.

[0136] In some embodiments, the distance between the outer side surface of the water outlet pipe 21 and the hole wall of the through hole is less than or equal to 0.4 mm. Wherein, one end of the water outlet pipe 21 provided with the water outlet 212 extends into the partition plate 121 after passing through the through hole. The distance between the outer side surface of the water outlet pipe 21 and the hole wall of the through hole being less than or equal to 0.4 mm can ensure the complete sealing of the second end of the core body 20.

[0137] In a second aspect, an embodiment of the present invention further provides a water purification device, including: a machine body and the water purification component as above; the machine body has an installation cavity, and the water purification component is detachably arranged in the installation cavity.

[0138] Specifically, the water purification device can be an instant hot water dispenser. The machine body can be provided with an installation port communicated with the installation cavity, and the core body 20 can be inserted into the installation cavity through the installation port.

[0139] 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 elaborated one by one here.

[0140] 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 recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
