[0052] The following will Figures 1 to 14 , through specific embodiments and their application scenarios, provide a detailed description of the water purification component and water purification equipment provided by the embodiments of the present utility model.

[0053] In the first aspect, as Figure 1 , Figure 2 , Figure 3 and Figure 12 shown, the water purification component of the embodiments of the present utility model includes: a housing 1 and a capacitive deionization filter element 2. The capacitive deionization filter element 2 is disposed inside the housing 1. A gap is left between the outer side surface of the capacitive deionization filter element 2 and the inner wall of the housing 1, and a positioning structure is provided between the outer side surface of the capacitive deionization filter element 2 and the inner wall of the housing 1. A mutually isolated water outlet space 111 and an accommodation space 112 are formed between the first end of the capacitive deionization filter element 2 and the inner wall of the housing 1. The accommodation space 112 is located outside the water outlet space 111. The capacitive deionization filter element 2 has an inlet end in its radial direction and a water outlet 213 in its axial direction.

[0054] The housing 1 is provided with a first through hole 103 and a second through hole 104 communicating with the accommodation space 112, a water outlet port 102 communicating with the water outlet space 111, and an inlet port 101 communicating with the gap. The first through hole 103, the second through hole 104, the water outlet port 102, and the inlet port 101 are located on the same side of the housing 1. The water outlet end communicates with the water outlet space 111. The positive electrode conductor of the capacitive deionization filter element 2 sequentially passes through the accommodation space 112 and the first through hole 103, and the negative electrode conductor of the capacitive deionization filter element 2 sequentially passes through the accommodation space 112 and the second through hole 104.

[0055] 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. The inlet port 101 and the water outlet port 102 are respectively located at the first end of the housing 1 and communicate with the accommodation cavity.

[0056] In addition, the first through hole 103 corresponds to the positive electrode conductor, and the second through hole 104 corresponds to the negative electrode conductor. Exemplarily, the positive electrode conductor can pass through the first through hole 103, and the negative electrode conductor can pass through the second through hole 104. In this way, the external power supply of the positive electrode conductor and the negative electrode conductor can be realized.

[0057] It should be noted that an isolated water outlet space 111 and a receiving space 112 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, and 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 conductor and the negative electrode conductor of the capacitive deionization filter element 2 are arranged in the receiving space 112, and the water outlet 213 of the capacitive deionization filter element 2 is arranged in the water outlet space 111, this design realizes the electrical and water isolation of the water purification component based on the mutually isolated water outlet space 111 and the receiving space 112, ensuring the reliability of the water purification work of the water purification component. In addition, a positioning structure is arranged between the outer side surface of the capacitive deionization filter element 2 and the inner wall of the housing 1. For example, the positioning structure includes a mutually cooperating groove 331 and a protrusion 11. In this way, when the capacitive deionization filter element 2 and the housing 1 are assembled, the docking accuracy between the positive electrode conductor and the first through hole 103 and the docking accuracy between the negative electrode conductor and the second through hole 104 can be ensured.

[0058] In some embodiments, as Figure 2 and Figure 3 shown, a first partition 121 and a second partition 122 are arranged 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 a water outlet space 111, and the first partition 121, the second partition 122 and the first end of the capacitive deionization filter element 2 enclose a receiving space 112.

[0059] It can be understood that the first partition 121 and the second partition 122 are respectively arranged on the inner wall of the first end of the housing 1, the water outlet port 102 is arranged at the center of the first end of the housing 1, and the first partition 121 and the second partition 122 respectively extend circumferentially relative to the water outlet port 102 in a ring shape. Since the second partition 122 is located outside the first partition 121, the receiving space 112 is located outside the water outlet space 111.

[0060] In practical applications, only by abutting the first end of the capacitive deionization filter element 2 against the inner wall of the first end of the housing 1, the water outlet space 111 and the 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 based on the first partition 121 and the second partition 122.

[0061] In some embodiments, as Figure 2 、 Figure 3 、 Figure 8 andFigure 11 As shown, the capacitive deionization filter element 2 includes a first end cap 3 and a core body 20. The first end cap 3 includes a side wall 31, a top wall 32, and a first rubber blocking wall 33 that are sequentially bent and connected. The side wall 31 is connected to the inner side surface of the second partition plate 122. The top wall 32 is clamped between the first end of the core body 20 and the second partition plate 122. The first rubber blocking wall 33 is connected to the outer side surface of the core body 20. The positive electrode conductor and the negative electrode conductor are located in the area enclosed by the side wall 31 and the first partition plate 121. Among them, a positioning structure is provided between the outer side surface of the first end cap 3 and the inner wall of the housing 1.

[0062] It can be understood that the top wall 32 is in the shape of a disc. The top wall 32 is provided with a central hole, and the central hole is coaxially arranged with the water outlet port 102. The side wall 31 extends circumferentially relative to the central hole. The positive electrode conductor, the negative electrode conductor, and the water outlet 213 of the core body 20 pass through the central hole.

[0063] When the first end of the core body 20 abuts against the inner wall of the first end of the housing 1, the outer side surface of the side wall 31 is hermetically connected to the inner side surface of the second partition plate 122. A closed accommodation space 112 is formed between the side wall 31, the first partition plate 121, and the first end of the core body 20. Waterproof isolation of the positive electrode conductor and the negative electrode conductor can be achieved based on the accommodation space 112.

[0064] 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 hermetically connected. This design can ensure that the water body output from the water outlet 213 directly discharges from the water outlet port 102 after entering the water outlet space 111, and the water body in the water outlet space 111 will not flow into the accommodation space 112.

[0065] In practical applications, the top wall 32 and the first end of the core body 20 are hermetically connected by filling glue. The inner side surface of the first rubber blocking wall 33 is attached to the peripheral wall of the core body 20. Among them, a water passing gap is left between the outer side surface of the first rubber blocking wall 33 and the inner wall of the housing 1. The water inlet port 101 is communicated with the gap through the water passing gap.

[0066] 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 core body 20. The first rubber blocking wall 33 is arranged on the outer edge of the top wall 32 and extends circumferentially relative to the central hole. The inner diameter of the first rubber blocking wall 33 is adapted to the diameter of the core body 20.

[0067] Optionally, in order to ensure the sealing effect of the first end of the core body 20, the side surface of the top wall 32 facing the core body 20 is provided with a first support rib. 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 thickness of the filling glue filled at the first end of the core body 20 and is beneficial to ensuring the molding quality of the filling glue.

[0068] In an alternative embodiment, such asFigure 12 As shown, in order to ensure the molding quality of the filling glue, a glue baffle 321 is further provided on one side of the top wall 32 facing the core body 20, and it is arranged close to the side wall 31. That is to say, the glue baffle 321 is arranged along the inner edge of the top wall 32 and extends circumferentially relative to the central hole. The glue baffle 321 is used to limit the flow of the filling glue towards the area where the central hole is located.

[0069] In an alternative embodiment, such as Figure 8 and Figure 11 shown, a plurality of spaced-apart abutting portions 332 are provided on the outer side surface of the first glue baffle wall 33, and the abutting portions 332 abut against the inner wall of the housing 1.

[0070] In other words, bumps can be provided on the outer side surface of the first glue baffle wall 33, and the bumps abut against the inner wall of the housing 1, so as to form a water passing gap between the outer side surface of the first glue baffle wall 33 and the inner wall of the housing 1.

[0071] In an alternative embodiment, such as Figure 8 and Figure 12 shown, 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 baffle wall 33. Thus, in the case of assembling the capacitive deionization filter element 2 and the housing 1, the docking accuracy between the positive electrode conductor and the first through hole 103 and the docking accuracy between the negative electrode conductor and the second through hole 104 can be ensured.

[0072] In an alternative embodiment, such as Figure 8 , Figure 9 and Figure 11 shown, the capacitive deionization filter element 2 further includes an annular fixing seat 6. The annular fixing seat 6 is provided with a first positioning hole 611 adapted to the positive electrode conductor and a second positioning hole adapted to the negative electrode conductor. The annular fixing seat 6 is detachably arranged on the side wall 31 and is located in the accommodation space 112. The positive electrode conductor passes through the first positioning hole 611 and the first through hole 103 in sequence, and the negative electrode conductor passes through the second positioning hole and the second through hole 104 in sequence. Among them, the annular fixing seat 6 is sleeved on the outer side surface of the first partition plate 121.

[0073] Thus, through the first positioning hole 611 and the second positioning hole, the coaxiality of the positive electrode conductor and the negative electrode conductor can be ensured, and the docking progress between the positive electrode conductor and the first through hole 103 and the docking progress between the negative electrode conductor and the second through hole 104 can be further improved.

[0074] In some embodiments, such as Figure 8 and Figure 9As shown, 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 one 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.

[0075] Specifically, the top plate 61 abuts against the top of the side wall 31, and the side plate 62 is in interference fit with the inner side surface of the side wall 31. In this way, the connection between the annular fixing base 6 and the first end cap 3 can be realized, ensuring the relative fixation of the annular fixing base 6 and the first end cap 3, so as to prevent the first positioning hole 611 from shifting relative to the positive electrode conductor and the second positioning hole from shifting relative to the negative electrode conductor.

[0076] In some embodiments, as Figure 8 and Figure 9 shown, 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 cap 3 are in limit fit in the circumferential direction of the installation space through the clamping groove 621 and the clamping buckle 311.

[0077] Specifically, a clamping groove 621 is provided on the side of the side plate 62 away from the top plate 61, and a clamping buckle 311 is provided on the inner side surface of the side wall 31. In this way, the annular fixing base 6 and the first end cap 3 are in limit fit in the circumferential direction of the installation space through the clamping groove 621 and the clamping buckle 311, further improving the installation stability of the annular fixing base 6 and the first end cap 3.

[0078] 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 body 20. The tab is detachably electrically connected to the electrical connection member, and the electrical connection member sequentially passes through the corresponding positioning hole and through hole.

[0079] Specifically, the power connection assembly 5 includes a positive electrode electrical connection member 51 and a negative electrode electrical connection member 52. The core body 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 sequentially pass through the first positioning hole 611 and the first through hole 103. 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 sequentially pass through the second positioning hole and the second through hole 104.

[0080] In some embodiments, 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 electrical connection member is provided with an abutting surface, and the abutting surface abuts against the stepped surface.

[0081] That is to say, under the action of the annular fixing 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 to avoid squeezing and damaging the tab.

[0082] In some embodiments, such as Figure 2 , Figure 9 and Figure 12 shown, 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.

[0083] In practical applications, such as Figure 8 , Figure 9 , Figure 10 and Figure 11 shown, first, a layer of filling glue is provided in the first area at the first end of the core body 20, and the first area is 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 core body 20. Since the first glue-blocking wall 33 is attached to 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 radially to ensure the coaxiality between the core body 20 and the water outlet port 102. Next, a layer of filling glue is provided in the second area at the first end of the core body 20, and the second area corresponds to the area where the central hole is located on the top wall 32, so as to complete the sealing of the first end of the core body 20. Subsequently, the annular fixing seat 6 is installed on the side wall 31. Under the limiting cooperation of the card slot 621 and the buckle 311, the first positioning hole 611 can correspond to the positive tab 201, and the second positioning hole can correspond to the negative tab 202. Then, the positive electrical connector 51 is installed in the first positioning hole 611 and completes the plug-in fit with the positive tab 201, and the negative electrical connector 52 is installed in the second positioning hole and completes the plug-in fit with the negative tab 202. That is to say, under the action of the annular fixing 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 to avoid damaging the tab.

[0084] In some embodiments, such as Figure 2 , Figure 3 , Figure 10 and Figure 11 shown, the capacitive deionization filter element 2 further includes: a second end cap 4;

[0085] 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 hermetically connected to the second end of the core body 20 through a filling rubber, and the second rubber blocking wall 42 is attached to the peripheral wall of the core body 20.

[0086] It can be understood that the bottom wall 41 is disc-shaped, the filling rubber forms a sealing rubber layer at the second end of the core body 20, and the bottom wall 41 is attached to the surface of the sealing rubber layer to achieve the sealing of the second end of the core body 20.

[0087] The second rubber blocking wall 42 is arranged 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 rubber blocking wall 42 is adapted to the diameter of the core body 20, and the second rubber blocking wall 42 is used to prevent the filling rubber from overflowing to the peripheral wall of the core body 20.

[0088] Furthermore, a second support rib can also be 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 water outlet pipe 21. The second support rib is used to ensure the thickness of the filling rubber filled at the second end of the core body 20 and is beneficial to ensuring the molding quality of the filling rubber. 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 7 shown, the core body 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 used to receive the input of raw water, and the inside of the electrode assembly 22 is used to output purified water or waste water;

[0090] The water outlet pipe 21 has a water outlet channel 211, water passing holes 212 communicating with the water outlet channel 211, and a water outlet 213. The water outlet channel 211 is arranged inside the water outlet pipe 21. The water outlet channel 211 forms a water outlet 213, and the water passing holes 212 are 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 passing holes 212 are arranged on the peripheral wall near the second end of the water outlet pipe 21.

[0091] It can be understood that the electrode assembly 22 generally includes a positive electrode plate and a negative electrode plate which are stacked. The positive electrode plate and the negative electrode plate are isolated from each other, and a flow channel for the water body to flow 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.

[0092] Since the electrode assembly 22 is wound around the peripheral wall of the water outlet pipe 21 and both 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. Thus, 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 application 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, and thus wastewater with a higher concentration is output from the inner side of the electrode assembly 22.

[0093] Considering that a plurality of water passing holes 212 are usually densely arranged on the peripheral wall of the existing water outlet pipe 21, the water body 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 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 this application, by arranging the water passing holes 212 on the peripheral wall close to 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 body 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 for output. Then, 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 air bubbles generated in the electrode assembly 22 towards the area where the water passing holes 212 are located, and then enter the water outlet channel 211 from the water passing holes 212 and be discharged together with the water body, thereby effectively removing the air bubbles appearing in the core body 20.

[0094] 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 body 20, it can effectively discharge the air bubbles generated in the filter element, prevent the core body 20 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 core body 20.

[0095] It should be noted here that as Figure 4 shown, 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, and a plurality of water passing openings 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 openings, 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 6As shown, a flow guiding groove 214 is provided on the peripheral wall of the water outlet pipe 21, and a fluid communication is formed between the flow guiding groove 214 and the water passing holes 212.

[0097] It can be understood that by providing the flow guiding groove 214 on the peripheral wall of the water outlet pipe 21, the gap between the inner side of the electrode assembly 22 and the peripheral wall of the water outlet pipe 21 can be prevented from being too small to cause current limiting to the water body, so as to facilitate collecting the purified water output from the inner side of the electrode assembly 22 by the flow guiding groove 214 and then guiding the collected purified water into the water passing holes 212.

[0098] Among them, the depth of the flow guiding 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 length of the electrode assembly 22 along the axial direction of the central axis, one end of the flow guiding 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, so that the flow guiding groove 214 can effectively collect the purified water output from the inner side of the electrode assembly 22 at various positions along the axial direction of the water outlet pipe 21, ensuring the drainage effect of the purified water.

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

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

[0102] Meanwhile, since the inner and outer ends of the electrode assembly 22 are correspondingly formed as the water outlet end and the water inlet end relative to the water outlet pipe 21, 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 flow guiding groove 214 to extend along the axial direction of the water outlet pipe 21, it is convenient to relatively arrange the flow guiding groove 214 with the water outlet end of the electrode assembly 22, ensuring the drainage effect of the purified water.

[0103] In some embodiments, as Figure 6 shown, in order to enhance the drainage effect of the purified water, both the flow guiding groove 214 and the water passing holes 212 are provided with a plurality of them, the plurality of flow guiding 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 channel 214 may be configured to form a fluid communication with a plurality of water passing holes 212 arranged axially along the water outlet pipe 21, and each diversion channel 214 extends along the axial direction of the water outlet pipe 21.

[0105] Optionally, the plurality of diversion channels 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 circumferentially along the water outlet pipe 21, and the plurality of diversion channels 214 are also arranged circumferentially along the water outlet pipe 21. Each diversion channel 214 extends along the axial direction of the water outlet pipe 21.

[0106] In some embodiments, there may be a plurality of water passing holes 212, and the sum of the water passing areas of the plurality of water passing holes 212 is not less than 20 mm². For example, the sum of the water passing areas of the plurality of water passing holes 212 is 20 mm², 25 mm², 35 mm², 50 mm², etc. This design avoids a large flow resistance when the water body passes through the water passing holes 212 and prevents the water passing holes 212 from restricting the flow of the water body.

[0107] In some embodiments, in order to ensure the exhaust effect of the core 20, the proportion of the axial distance between the water passing holes 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 core 20 is approximately 333 - 350 mm, and the axial distance between the water passing holes 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 holes 212 are as far away as possible from the water outlet 213 of the core 20, thereby ensuring the exhaust effect.

[0109] In some embodiments, 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. The 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 electrode assembly 22 is correspondingly formed as a water outlet end and a water inlet end with respect to the inner and outer ends of the water outlet pipe 21; 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 water passing holes 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 a 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 a 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 core 20 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 core 20 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 core 20 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, 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 sides of the current collector layer 2221 of each electrode sheet 222, both sides 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.

[0119] In some embodiments, to ensure the purification effect of the raw water, the adjacent two layers of electrode sheets 222 are oppositely arranged 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.

[0120] Further, by arranging the insulating sheet 221 and the electrode sheet 222 to be misaligned 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 water passing holes 212 and / or the diversion grooves 214 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 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, a plurality of groups of water passing holes 212 are arranged along the circumferential direction of the peripheral wall of the water outlet pipe 21. For example, the plurality of groups of water passing holes 212 are uniformly 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 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 water passing holes 212.

[0122] 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.

[0123] Meanwhile, by arranging a plurality of water outlet ends opposite to the plurality of 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 outlet flow rate of the purified water of the core body 20.

[0124] In some embodiments, such as Figure 2 , Figure 4 and Figure 7 shown, in order to facilitate the connection of the 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.

[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 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.

[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, 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.

[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 woven fabric or insulating grid. The insulating woven fabric can be woven fabric or meltblown 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 risk of blockage. 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, the 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, the 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 machine body and the water purification component as above; the machine 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 machine body may be provided with an installation port communicating with the installation cavity, and the core body 20 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 elaborated 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 limiting 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 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.
