In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0056] The following combination Figures 1 to 14 , the water purification component and water purification equipment provided by the embodiment of the utility model are described in detail through specific embodiments and their application scenarios.

[0057] like Figure 2 、 Figure 3 、 Figure 9 、 Figure 10 、 Figure 13 and Figure 14 As shown, the water purification component of the embodiment of the present utility model includes: a fixing seat 6, an electrical connection component 5, a first end cover 3 and a capacitor deionization filter element 2.

[0058] The capacitor deionizing filter element 2 has a water inlet end along its radial direction and a water outlet 212 along its axial direction. The first end of the capacitor deionizing filter element 2 has a positive electrode tab 201 and a negative electrode tab 202. The water outlet 212 is provided at the second end of the capacitor deionizing filter element 2.

[0059] The first end cap 3 includes a top wall 32 and a side wall 31 connected to each other. The top wall 32 is glued to the first end of the capacitor deionization filter element 2. The side wall 31 encloses an installation space. The top wall 32 is provided with a first through hole 322 and a second through hole. The positive electrode tab 201 is inserted into the first through hole 322 and extends into the installation space. The negative electrode tab 202 is inserted into the second through hole and extends into the installation space.

[0060] The fixing seat 6 is provided on the side wall 31 and is provided with a first positioning hole 62 corresponding to the positive electrode tab 201 and a second positioning hole corresponding to the negative electrode tab 202;

[0061] The power connection assembly 5 includes a positive electrical connector 51 and a negative electrical connector 52. The positive electrical connector 51 is installed in the first positioning hole 62 and is detachably connected to the positive electrode tab 201. The negative electrical connector 52 is installed in the second positioning hole and is detachably connected to the negative electrode tab 202.

[0062] Exemplarily, the positive electrode electrical connector 51 is plugged into the positive electrode tab 201, and the negative electrode electrical connector 52 is plugged into the negative electrode tab 202. The positive electrode electrical connector 51 and the negative electrode electrical connector 52 are used to connect to an external power source.

[0063] Specifically, under the positioning and support of the first positioning hole 62 of the fixing base 6, the positive electrode electrical connector 51 can be installed in the first positioning hole 62 and directly connected to the positive electrode tab 201. Under the positioning and support of the second positioning hole of the annular fixing base 6, the negative electrode electrical connector 52 can be installed in the second positioning hole and directly connected to the negative electrode tab 202. In this way, an efficient, stable and safe electrical connection can be achieved, thereby improving the reliability and service life of the equipment.

[0064] In some embodiments, as Figure 13 As shown, each of the first positioning hole 62 and the second positioning hole is a stepped hole with a stepped surface. The outer side surface of each of the positive and negative electrical connectors 51 and 52 is provided with an abutment surface, which abuts the stepped surface. The electrical connectors have a conductive surface and a connection surface, which are arranged opposite each other. The conductive surface is used to connect to an external power source, and the connection surface is used to connect to the tab. The conductive surface of each electrical connector is flush with the side of the fixing seat 6 facing away from the top wall 32.

[0065] That is to say, under the action of the fixing seat 6, the coaxiality of the electrical connector and the tab can be ensured, and the electrical connector will not move excessively during the docking process to avoid squeezing damage to the tab.

[0066] like Figure 9 and Figure 13 As shown, in order to further improve the installation stability of the fixing seat 6 and the first end cover 3, the fixing seat 6 is detachably arranged on the inner side surface of the side wall 31, and a slot 61 is provided on the side of the fixing seat 6 facing the top wall 32, and a 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 limited in the circumferential direction by the slot 61 and the buckle 311.

[0067] In addition, each of the positive and negative electrical connectors 51 and 52 has a slot on its connection surface, into which the corresponding tab is inserted. For example, the bottom of the positive electrical connector 51 may be provided with a slot, and the positive tab 201 may be in the form of a sheet, which can be inserted into the slot of the positive electrical connector 51. This ensures quick and stable connection between the electrical connector and the tab.

[0068] In some embodiments, as Figure 1 、 Figure 2 and Figure 3 As shown, the water purification component also includes a housing 1, a capacitive deionizing filter element 2 is disposed in the housing 1, a first gap is left between the outer side surface of the capacitive deionizing filter element 2 and the inner wall of the housing 1, and a side wall 31 away from the top wall 32 is connected to the inner wall of the housing 1;

[0069] In which, the shell 1 is provided with a first plug hole 103, a second plug hole 104, a water outlet port 102 and a water inlet port 101 connected to the first gap. The water outlet port 102 and the water inlet port 101 are located on one side of the shell 1, the first plug hole 103 and the second plug hole 104 are located on the other side of the shell 1, the water outlet 212 is connected to the water outlet port 102, at least part of the positive electrical connector 51 is exposed in the first plug hole 103, and at least part of the negative electrical connector 52 is exposed in the second plug hole 104.

[0070] It is understandable that the housing 1 is cylindrical, a receiving cavity is provided in the housing 1 , the capacitive deionization filter element 2 is installed in the receiving cavity, and is configured to be coaxial with the housing 1 .

[0071] 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 capacitor deionization filter element 2; the side wall 31 is arranged on the side of the top wall 32 away from the capacitor deionization filter element 2, and abuts against the inner wall of the first end of the shell 1, so that the top wall 32, the side wall 31 and the inner wall of the shell 1 enclose a receiving space 112.

[0072] In an optional embodiment, if Figure 2 and Figure 13 As shown, to ensure accurate connection between the external power source and the positive and negative electrical connectors 51 and 52, the positive and negative electrical connectors 51 and 52 are located inside the housing 1. The projected area of ​​the first insertion hole 103 on the top wall 32 is less than or equal to the projected area of ​​the conductive surface of the positive electrical connector 51 on the top wall 32, and the projected area of ​​the second insertion hole 104 on the top wall 32 is less than or equal to the projected area of ​​the conductive surface of the negative electrical connector 52 on the top wall 32. In other words, the positive electrical connector 51 does not extend into the first insertion hole 103, and the negative electrical connector 52 does not extend into the first insertion hole 103. The external positive power supply terminal can enter the first insertion hole 103 to connect with the positive electrical connector 51, and the external negative power supply terminal can enter the second insertion hole 104 to connect with the negative electrical connector 52.

[0073] In some embodiments, as Figure 2 、 Figure 3 and Figure 9 As shown, the first end cover 3 also includes: a first glue blocking wall 33 bent and connected to the top wall 32, the outer side surface of the first glue blocking wall 33 is sealed with the inner wall of the shell 1, the top wall 32 and the first end of the capacitor deionization filter element 2 are sealed by filling glue, and the inner side surface of the first glue blocking wall 33 is in contact with the outer side surface of the capacitor deionization filter element 2.

[0074] It is understandable that the filling glue forms a sealing glue layer at the first end of the capacitor deionization filter element 2 , and the top wall 32 is in contact with the surface of the sealing glue layer to achieve sealing of the first end of the capacitor deionization filter element 2 .

[0075] The first glue retaining wall 33 is arranged on 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 glue retaining wall 33 is adapted to the diameter of the capacitor deionization filter element 2. The first glue retaining wall 33 is used to prevent the filling glue from overflowing to the peripheral wall of the capacitor deionization filter element 2.

[0076] A first support rib can be provided on a side of the top wall 32 facing the capacitor deionization filter element 2. The first support rib can be configured to extend radially along the capacitor deionization filter element 2. The first support rib is used to ensure the thickness of the filling glue at the first end of the capacitor deionization filter element 2, and is conducive to ensuring the molding quality of the filling glue.

[0077] The outer side surface of the first rubber stop wall 33 is sealedly connected to the inner wall of the shell 1 to prevent water from entering the accommodating space 112 formed by the top wall 32 , the side wall 31 and the inner wall of the shell 1 .

[0078] In some embodiments, as Figure 2 As shown, in order to ensure the molding quality of the filling glue, the first end cover 3 also includes a glue baffle 321, which is arranged on the side of the top wall 32 facing the first end of the capacitor deionization filter element 2 and is close to the outer side surface of the capacitor deionization filter element 2.

[0079] That is, the annular glue blocking plate 321 is arranged on the inner side of the top wall 32, and the annular glue blocking plate 321 is arranged coaxially with the first glue blocking wall 33, and the glue blocking plate 321 is spaced apart from the first glue blocking wall 33. The glue blocking plate 321 is used to limit the filling glue from flowing toward the area where the through hole is located.

[0080] In some embodiments, as Figure 9 As shown, the projected area of ​​the first through hole 322 on the first end of the capacitor deionization filter element 2 is larger than the projected area of ​​the positive electrode tab 201 on the first end of the capacitor deionization filter element 2, and the projected area of ​​the second through hole on the first end of the capacitor deionization filter element 2 is larger than the projected area of ​​the negative electrode tab 202 on the first end of the capacitor deionization filter element 2.

[0081] In this way, it is convenient to seal the positive electrode tab 201 and the negative electrode tab 202 at the first end of the capacitor deionization filter element 2. That is to say, after the area between the rubber baffle plate 321 and the first rubber baffle wall 33 at the first end of the capacitor deionization filter element 2 is sealed, the remaining area of ​​the first end of the capacitor deionization filter element 2 (the area enclosed by the rubber baffle plate 321) is sealed through the first through hole 322 and the second through hole.

[0082] In some embodiments, as Figure 3 As shown, a partition 121 is provided on the inner wall of the housing 1 , and the partition 121 and the second end of the capacitor deionizing filter element 2 enclose a water outlet space 111 .

[0083] It can be understood that the partition 121 is extended circumferentially relative to the water outlet port 102, and the peripheral wall of the water outlet 212 of the capacitor deionization filter element 2 is sealed with the inner side surface of the partition 121, so that the partition 121 and the second end of the capacitor deionization filter element 2 enclose a water outlet space 111.

[0084] In some embodiments, as Figure 2 、 Figure 3 and Figure 10 As shown, the water purification component also includes: a second end cap 4, the second end cap 4 includes a bottom wall 41 and a second glue blocking wall 42 that are bent and connected, the bottom wall 41 is limited between the second end of the capacitor deionization filter element 2 and the side of the partition 121 away from the inner wall of the housing 1, and the bottom wall 41 is provided with a through hole, and the water outlet 212 is provided through the through hole and communicates with the water outlet space 111;

[0085] The bottom wall 41 is sealed to the second end of the capacitor deionizing filter element 2 by filling glue, the second glue retaining wall 42 is fitted to the peripheral wall of the capacitor deionizing filter element 2, a second gap is left between the outer side surface of the second glue retaining wall 42 and the inner wall of the shell 1, and the water inlet port 101 is connected to the first gap through the second gap.

[0086] It is understood that the filling glue forms a sealing glue layer at the second end of the capacitor deionization filter element 2. The second glue retaining wall 42 is provided on the outer edge of the bottom wall 41 and extends circumferentially relative to the water outlet 212. The inner diameter of the second glue retaining wall 42 is adapted to the diameter of the capacitor deionization filter element 2.

[0087] A plurality of ribs may be provided on the outer side surface of the second rubber stop wall 42, and the plurality of ribs are arranged along the circumference of the second rubber stop wall 42 and abut against the inner wall of the shell 1, so that a second gap is formed between the outer side surface of the second rubber stop wall 42 and the inner wall of the shell 1; of course, a plurality of ribs may also be provided on the inner wall of the shell 1, and the plurality of ribs are arranged along the circumference relative to the axis where the water outlet 212 is located, and abut against the outer side surface of the second rubber stop wall 42. This design can also form a second gap between the outer side surface of the second rubber stop wall 42 and the inner wall of the shell 1.

[0088] Furthermore, in order to ensure the sealing effect on the second end of the capacitor deionization filter element 2, a second support rib is provided on the side of the bottom wall 41 facing the capacitor deionization filter element 2. The second support rib can be configured to extend radially along the capacitor deionization filter element 2. The second support rib is used to ensure the thickness of the filling glue filled at the second end of the capacitor deionization filter element 2, and is conducive to ensuring the molding quality of the filling glue.

[0089] In practical applications, such as Figure 9 、 Figure 10 、 Figure 13 and Figure 14As shown, a layer of filling glue is first set in the first area of ​​the first end of the capacitor deionization filter element 2, and the first area is the area between the first glue blocking wall 33 and the glue blocking plate 321; then, the first end cover 3 is set on the first end of the capacitor deionization filter element 2. Since the first glue blocking wall 33 is in contact with the peripheral wall of the capacitor deionization filter element 2, and the first glue blocking wall 33 is extended 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 capacitor deionization filter element 2, but also limit the capacitor deionization filter element 2 radially to ensure the coaxiality of the capacitor deionization filter element 2 and the water outlet port 102. Next, a layer of filling glue is set in the second area of ​​the first end of the capacitor deionization filter element 2, and the second area is the area enclosed by the glue blocking plate 321, thereby completing the sealing of the first end of the capacitor deionization filter element 2. Subsequently, the fixing seat 6 is installed on the side wall 31. Under the limiting cooperation of the slot 61 and the buckle 311, the first positioning hole 62 can correspond to the positive pole ear 201, and the second positioning hole can correspond to the negative pole ear 202. After that, the positive pole electrical connector 51 is installed in the first positioning hole 62 and plugged into the positive pole ear 201. The negative pole electrical connector 52 is installed in the second positioning hole and plugged into the negative pole ear 202. That is to say, under the action of the fixing seat 6, the coaxiality of the docking between the electrical connector and the ear can be ensured, and it can be ensured that during the docking process between the electrical connector and the ear, the electrical connector will not move excessively to avoid damage to the ear.

[0090] It should be noted that the housing 1 can be configured as a first housing and a second housing. After the capacitor deionization filter element is installed in the first housing, the first housing and the second housing are connected.

[0091] In an optional embodiment, the capacitive deionization filter element 2 includes a water outlet pipe 21 and an electrode assembly 22. The electrode assembly 22 is wound around the peripheral wall of the water outlet pipe 21. The electrode assembly 22 is sealed at both ends along the axial direction of the water outlet pipe 21. The outer side of the electrode assembly 22 is used to receive the input of raw water, and the inner side of the electrode assembly 22 is used to output clean water or wastewater.

[0092] The water outlet pipe 21 has a water outlet channel and a first water hole 211 and a water outlet 212 connected to the water outlet channel. The water outlet channel is arranged in the water outlet pipe 21 , and the water outlet 212 is formed in the water outlet pipe 21 . The first water hole 211 is arranged on the peripheral wall of the water outlet pipe 21 .

[0093] Further, if Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the capacitive deionization filter element 2 of the embodiment of the present invention includes a water outlet pipe 21, a flow guide pipe 23 and an electrode assembly 22. The electrode assembly 22 is wound around the peripheral wall of the water outlet pipe 21. The electrode assembly 22 is sealed at both ends along the axial direction of the water outlet pipe 21. The outer side of the electrode assembly 22 is used to receive the input of raw water, and the inner side of the electrode assembly 22 is used to output clean water or wastewater.

[0094] The outlet pipe 21 has a first water hole 211 formed on its peripheral wall. A water outlet 212 is formed at the first end of the outlet pipe 21, and the second end of the outlet pipe 21 is sealed. The flow guide pipe 23 is disposed within the outlet pipe 21, forming a water gap 201 between the flow guide pipe 23 and the outlet pipe 21. The peripheral wall of the first end of the flow guide pipe 23 is sealedly connected to the inner wall of the outlet pipe 21, and a second water hole 202 is formed between the second end of the flow guide pipe 23 and the second end of the outlet pipe 21.

[0095] Among them, the first water flow hole 211, the water flow gap 201, the second water flow hole 202, the inner cavity of the guide pipe 23 and the water outlet 212 form fluid communication in sequence, and the outer diameter of the guide pipe 23 is smaller than the inner diameter of the outlet pipe 21 to form a water flow gap 201 between the guide pipe 23 and the outlet pipe 21.

[0096] It can be understood that the electrode assembly 22 generally includes stacked positive and negative electrodes, which are isolated from each other, and a flow channel for the flow of water is formed between the positive and negative electrodes; when the electrode assembly 22 is wound, the inner side surface of one end of the electrode assembly 22 contacts the peripheral wall of the water outlet pipe 21, and then the electrode assembly 22 is wound layer by layer with the water outlet pipe 21 as the central axis until the electrode assembly 22 is wound in a columnar distribution.

[0097] Since the electrode assembly 22 is wound around the peripheral wall of the water outlet pipe 21, the electrode assembly 22 is sealed at both ends along the axial direction of the water outlet pipe 21. When a positive voltage is applied to the positive electrode sheet and the negative electrode sheet, the cations, anions or charged particles in the water body will migrate to the surface of the positive electrode sheet and the negative electrode sheet under the action of the electric field force, so that the inner side of the electrode assembly 22 outputs the clean water after desalination treatment; when a reverse voltage is applied to the positive electrode sheet and the negative electrode sheet, or when the voltage is stopped, the anions, cations or charged particles adsorbed on the surface of the positive electrode sheet and the negative electrode sheet will automatically detach, so that the inner side of the electrode assembly 22 outputs wastewater with a higher concentration.

[0098] Considering that the surrounding wall of the existing water outlet pipe 21 is usually densely covered with multiple first water holes 211, the water output from the inner side of the electrode assembly 22 will evenly pass through each first water hole 211 and enter the water outlet channel. If bubbles appear in the electrode assembly 22, the bubbles may adhere to the surface of the positive electrode sheet and / or the negative electrode sheet, and the flowing water will not have an effect on the desorption of the bubbles. However, the present application provides a guide tube 23 through the water outlet pipe 21, and provides a second water hole 202 between the second end of the guide tube 23 and the second end of the water outlet pipe 21, so that the second water hole 202 is set away from the water outlet 212. This design can limit the water output from the inner side of the electrode assembly 22 to gradually converge toward the area where the second water hole 202 is located after entering the water gap 201 from the first water hole 211, and then enter the guide tube 23 through the second water hole 202, and finally be output from the water outlet 212 under the guidance of the guide tube 23. In the process of water flow, since the second water hole 202 is set away from the water outlet 212, the flowing water gradually converges toward the area where the second water hole 202 is located, which will gradually squeeze the bubbles generated in the electrode assembly 22 to the area where the second water hole 202 is located, and then be discharged together with the water under the guidance of the guide tube 23, thereby effectively removing the bubbles appearing in the capacitor deionization filter element 2.

[0099] From the above, it can be seen that the water purification component shown in the utility model can effectively discharge the bubbles generated in the filter element 2 during the desalination process of the capacitor deionization filter element 2, prevent the capacitor deionization filter element 2 from generating noise during operation, ensure the stability of the internal electric field of the electrode assembly 22, and thus also ensure the water purification effect of the capacitor deionization filter element 2.

[0100] It should be pointed out here that the capacitive deionization filter element 2 also includes a protective cover, for example, the protective cover is a cylindrical film, the protective cover is arranged on the peripheral wall of the electrode assembly 22, and a plurality of water outlets are constructed on the protective cover to ensure that the water body can reach the outside of the electrode assembly 22 through the water outlet, and then the electrode assembly 22 desalinates the received water body.

[0101] In some embodiments, as Figure 6 and Figure 7 As shown, a blocking member 230 is provided in the water outlet pipe 21, and the blocking member 230 is arranged at a position close to the second end of the water outlet pipe 21; the peripheral wall of the first end of the guide pipe 23 is sealedly connected to the inner wall of the first end of the water outlet pipe 21, and a second water hole 202 is formed between the second end of the guide pipe 23 and the blocking member 230.

[0102] It is understandable that the axial distance between the blocking member 230 and the second end of the water outlet pipe 21 is smaller than the axial distance between the blocking member 230 and the first end of the water outlet pipe 21 .

[0103] The length of the flow conduit 23 can be configured so that the axial length between the sealing member 230 and the first end of the outlet pipe 21 is equal. A sealing ring can be used to achieve a sealed connection between the peripheral wall of the first end of the flow conduit 23 and the inner wall of the first end of the outlet pipe 21. The second end of the flow conduit 23 can be configured to abut the sealing member 230. However, a gap is reserved between the second end of the flow conduit 23 and the sealing member 230 to form the aforementioned second water passage 202.

[0104] Further, if Figure 7 As shown, the sealing member 230 includes: a sealing plate 2301 and a plurality of protrusions 2302; the sealing plate 2301 is connected to the inner wall of the water outlet pipe 21, for example, the periphery of the sealing plate 2301 is connected to the inner wall of the water outlet pipe 21; the plurality of protrusions 2302 are arranged on the side of the sealing plate 2301 facing the water outlet 212, and the plurality of protrusions 2302 are arranged at intervals along the circumferential direction, and the second end of the guide tube 23 abuts against at least part of the plurality of protrusions 2302, and a second water hole 202 is formed between two adjacent protrusions 2302.

[0105] It is understandable that since the multiple protrusions 2302 are arranged at intervals along the circumferential direction, there are multiple second water holes 202, and the multiple second water holes 202 are limited to be arranged along the circumferential direction, and each second water hole 202 can achieve fluid communication between the water gap 201 and the inner cavity of the guide tube 23.

[0106] In some embodiments, in order to ensure the exhaust effect of the capacitor deionization filter 2, the axial distance between the blocking member 230 and the second end of the water outlet pipe 21 is set to be no more than 15% of the length of the water outlet pipe 21.

[0107] It is understandable that, since the second water hole 202 is formed between the second end of the guide tube 23 and the blocking member 230 , the axial length between the second water hole 202 and the water outlet 212 accounts for no more than 15% of the length of the outlet pipe 21 .

[0108] Optionally, the length of the capacitor deionization filter element 2 is approximately 333-350 mm, and the axial distance between the sealing member 230 and the second end of the outlet pipe 21 can be set to be less than 50 mm, so that the second water hole 202 is as far away from the water outlet 212 of the capacitor deionization filter element 2 as possible, thereby ensuring the exhaust effect.

[0109] In some embodiments, multiple second water holes 202 are provided, and the total water flow area of ​​the multiple second water holes 202 is no less than 20 mm². For example, the total water flow area of ​​the multiple second water holes 202 is 20 mm², 25 mm², 35 mm², and 50 mm². This design avoids significant flow resistance when water passes through the second water holes 202, preventing the second water holes 202 from restricting the flow of water.

[0110] In some embodiments, as Figure 8 、 Figure 10 and Figure 12 As 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 stacked, and the insulating sheet 221 is sandwiched between two adjacent layers of electrode sheets 222;

[0111] The electrode sheet 222 includes a current collector layer 2221 and an adsorption layer 2222. The adsorption layer 2222 is provided on both the front and back sides of the current collector layer 2221. Two adjacent electrode sheets 222 are configured as a positive electrode sheet and a negative electrode sheet, respectively. A water passage 2201 for accommodating the insulating sheet 221 is formed between the positive electrode sheet and the negative electrode sheet.

[0112] The inner and outer ends of the electrode assembly 22 relative to the water outlet pipe 21 are correspondingly formed as a water outlet end and a water inlet end; the water inlet end is connected to the water outlet end through the water passage 2201, and the water outlet end extends to the peripheral wall of the water outlet pipe 21 and forms a fluid connection with the first water hole 211.

[0113] It is understood that the insulating sheets 221 and electrode sheets 222 are stacked in an alternating arrangement so that the insulating sheet 221 is sandwiched between two adjacent layers of electrode sheets 222. Since the two adjacent layers of electrode sheets 222 are configured as positive and negative electrodes, respectively, when the number of electrode sheets 222 is greater than two, in order to meet the raw water filtration requirements of the electrode assembly 22, when the electrode assembly 22 is powered, the positive and negative electrodes can be arranged alternately in the stacking direction, with the insulating sheet 221 sandwiched between the positive and negative electrodes. Furthermore, 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, the insulating sheet 221 can be directly sandwiched between the positive and negative electrodes.

[0114] 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 forms a conductive layer, and the adsorption layer 2222 of the electrode sheet 222 can be made of activated carbon and other adsorption materials to achieve adsorption of ions in the raw water.

[0115] 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, not only preventing the positive electrode sheet and the negative electrode sheet from short-circuiting, but also ensuring that a water channel 2201 is formed between the positive electrode sheet and the negative electrode sheet.

[0116] In practice, the capacitive deionization filter element 2 operates through an adsorption purification process and a desorption regeneration process. When two adjacent electrode sheets 222 are electrically connected to the positive and negative poles of a power source and the power supply is activated, the anions and cations in the raw water are attracted to the oppositely charged electrode sheet 222 and adsorbed by the adsorption layer 2222 on the electrode sheet 222. This operation of the capacitive deionization filter element 2 is the adsorption purification process.

[0117] Accordingly, when the power supply is stopped or a reverse voltage is applied to two adjacent electrode sheets 222, the ions adsorbed by the adsorption layer 2222 are released into the water body of the water channel 2201. At this time, the water channel 2201 will output concentrated water with a higher ion concentration.

[0118] As can be seen from the above, the capacitive deionization filter element 2 shown in this embodiment realizes the integrated design of the electrode sheet 222 by setting the adsorption layer 2222 on the front and back sides of the current collector layer 2221. It is only necessary to stack the electrode sheet 222 and the insulating sheet 221 in an alternating arrangement to form the electrode assembly 22; this stacking arrangement design of the electrode assembly 22 simplifies the arrangement structure of the electrode assembly 22, facilitates processing and production, and helps to reduce production costs.

[0119] At the same time, in actual applications, simply electrically connecting two adjacent layers of electrode sheets 222 to the positive and negative poles of a power source can adsorb ions in the raw water passing through water passage 2201, achieving the purpose of raw water purification. Because 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, thereby ensuring a certain degree of raw water purification. The capacitive deionization filter element 2 can effectively remove heavy metal ions from water, retaining beneficial ions required by the human body, and meeting the needs of household water purification.

[0120] In some embodiments, in order to ensure the purification effect of raw water, two adjacent layers of electrode sheets 222 are arranged relative to each other along the stacking direction to ensure the coverage range of the electric field between the two adjacent 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 two adjacent layers of electrode sheets 222.

[0121] Furthermore, by staggering the insulating sheets 221 and the electrode sheets 222 along the stacking direction, the electrode sheets 222 are hidden between two adjacent layers of insulating sheets 221. This design not only ensures electrical isolation between two adjacent layers of electrode sheets 222, but also facilitates positioning the water outlet end of the electrode assembly 22 at a position opposite to the first water hole 211 on the peripheral wall of the water outlet pipe 21, thereby ensuring unimpeded fluid flow between the water passage 2201 in the electrode assembly 22 and the water gap 201 inside the water outlet pipe 21.

[0122] Among them, such as Figure 11 As shown, the stacking direction is along the thickness direction of the insulating sheet 221 or the electrode sheet 222 .

[0123] In some embodiments, as Figure 6 and Figure 8 As shown, the peripheral wall of the water outlet pipe 21 is provided with a plurality of groups of first water holes 211 along the circumferential direction, and each group of first water holes 211 is arranged along the axial direction of the water outlet pipe 21;

[0124] The number of electrode sheets 222 is greater than two layers, so that the electrode assembly 22 forms multiple water channels 2201; the inner end of the electrode assembly 22 forms multiple water outlet ends corresponding to the multiple water channels 2201, and the multiple water outlet ends are arranged opposite to the multiple groups of first water holes 211.

[0125] It is understandable that by setting the number of electrode sheets 222 to be greater than two layers, multiple water channels 2201 can be formed based on the electrode assembly 22, and the raw water flowing in multiple paths in the capacitor deionization filter element 2 can be purified at the same time, thereby improving the purification efficiency of the raw water.

[0126] At the same time, by setting multiple water outlet ends and multiple groups of first water holes 211 relative to each other, the smoothness of the water path between each water channel 2201 and the water gap 201 inside the outlet pipe 21 can be ensured, which is beneficial to ensuring the clean water outlet flow rate of the capacitor deionization filter element 2.

[0127] In actual applications, while ensuring electrical isolation between two adjacent layers of electrode sheets 222, the insulating sheet 221 at one end of the electrode assembly 22 close to the water outlet pipe 21 and the end of the electrode sheet 222 can be staggered in sequence along the extension direction of the electrode sheet 222 and arranged along the circumference of the water outlet pipe 21.

[0128] In some embodiments, as Figure 3 、 Figure 4 and Figure 8 As shown, in order to facilitate the connection of two adjacent electrode sheets 222 to the positive and negative poles of the power supply, the electrode assembly 22 also 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.

[0129] Specifically, a first extension portion is provided on one side of the current collector layer 2221 of each positive electrode sheet, and a second extension portion is provided on one side of the current collector layer 2221 of each negative electrode sheet; when the electrode assembly 22 is wound around the peripheral wall of the water outlet pipe 21, the first extension portions of each positive electrode sheet are stacked to form a positive electrode tab 201, and the second extension portions of each negative electrode sheet are stacked to form a negative electrode tab 202.

[0130] 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 electrode or the negative electrode of the power source.

[0131] The adsorption layer 2222 is attached to the surface of the current collector layer 2221 . The adsorption layer 2222 includes an activated carbon layer. The activated carbon layer has excellent adsorption properties and can adsorb ions in the raw water.

[0132] In some embodiments, since the thickness of the current collector layer 2221 of the electrode sheet 222 determines the supporting 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, so 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.

[0133] 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 may crack during winding, so 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.

[0134] In some embodiments, the insulating sheet 221 may be configured as a porous structure, for example, the insulating sheet 221 includes an insulating woven fabric or an insulating mesh. The insulating woven fabric may be a woven fabric or a melt-blown fabric.

[0135] In this way, although the insulating sheet 221 is arranged in the water channel 2201, 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, thereby not affecting 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 channel 2201, and can ensure the adsorption effect of the adsorption layer 2222 on ions to a certain extent.

[0136] 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 worse 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 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, etc.

[0137] In an optional embodiment, if Figure 3 As shown, one end of the water outlet pipe 21 provided with a water outlet 212 extends into the water outlet space 111 , and the outer side surface of the water outlet pipe 21 is sealedly connected to the inner wall of the water outlet space 111 .

[0138] 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 sealedly connected to the inner side surface of the partition 121, for example, by a sealing ring.

[0139] In a second aspect, an embodiment of the present invention further provides a water purification device, comprising: a body and the water purification component as described above; the body has an installation cavity, and the water purification component is detachably arranged in the installation cavity.

[0140] Specifically, the water purification device can be an instant hot water dispenser, and the body can be provided with an installation port communicating with the installation cavity, and the capacitor deionization filter element 2 can be inserted into the installation cavity through the installation port.

[0141] Since the water purification equipment includes a water purification component, the specific structure of the water purification component refers to the above embodiment, and the water purification equipment of this embodiment includes all the technical solutions of the above embodiment, and therefore has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here.

[0142] 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
