[0024] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] The application first proposes a purification device as shown in FIG. 1 and FIG. 2, which comprises a first shell 10, a purification assembly 20, and a first sealing member 30. The first shell 10 forms a flow-through hole 01, an electricity-through hole 02, and a first cavity 03 communicating with the flow-through hole 01 and the electricity-through hole 02. The purification assembly 20 comprises a purification body 21 and an electricity connection terminal 22. The purification body 21 is arranged in the first cavity 03. The first end of the electricity connection terminal 22 is connected with the purification body 21, and the second end of the electricity connection terminal 22 extends from the electricity-through hole 02 to outside of the first cavity 03. The first sealing member 30 is arranged in the first cavity 03, and the second end of the electricity connection terminal 22 penetrates through the first sealing member 30, so as to isolate the second end of the electricity connection terminal 22 from the liquid in the first cavity 03 through the first sealing member 30. The first shell 10 comprises two opposite end portions and a side portion connecting the two end portions. The electricity-through hole 02 is arranged on one of the two end portions and the side portion. The flow-through hole 01 is arranged on the other of the two end portions and the side portion.

[0026] The first shell 10 forms the first cavity 03 for arranging the purification body 21. The flow-through hole 01 is a through hole for guiding the liquid to flow into or out of the purification body 21. The electricity connection terminal 22 is used for electrically connecting the purification body 21 with an external power supply device, so as to supply power to the purification body 21. The electricity connection terminal 22 comprises a positive electrode terminal and a negative electrode terminal. The second end of the electricity connection terminal 22 can extend to outside of the first shell 10 or remain in the first shell 10. Specifically, it is not limited as long as the second end of the electricity connection terminal 22 can extend to outside of the first cavity 03 to be isolated from the liquid in the first cavity 03. For example, when the second end of the electricity connection terminal 22 extends to outside of the first cavity 03 and is located in the first shell 10, the external power supply device can be inserted into the first shell 10 to be electrically connected with the electricity connection terminal 22. The electricity-through hole 02 is a through hole for leading the electricity connection terminal 22 out of the first shell 10, so as to facilitate the purification body 21 to be connected with electricity through the electricity connection terminal 22.

[0027] The second end of the electricity connection terminal 22 is an electricity leading end, which can be connected with the external power supply device to lead electricity. The first sealing member 30 is arranged in the first cavity 03 to isolate the second end of the electricity connection terminal 22 from the liquid in the first cavity 03.

[0028] The beneficial effects of the above arrangement are that the first sealing member 30 can be used to isolate the second end of the power connection terminal 22 from the liquid in the first cavity 03, that is, to isolate the power lead end from the liquid in the first cavity 03, thereby reducing the risk of the liquid contacting the second end of the power connection terminal 22, thereby reducing the risk of short circuit when the power lead end of the power connection terminal 22 is connected to electricity, and improving the safety and reliability of the purification device in use; the power lead through hole 02 is arranged on one of the two end portions and the side portion, and the liquid lead through hole 01 is arranged on the other of the two end portions and the side portion, that is, the liquid lead through hole 01 and the power lead through hole 02 are not located on the same end portion or side portion of the first shell 10, facilitating the separate arrangement of the liquid lead through hole 01 and the power lead through hole 02, facilitating water and electricity separation, thereby reducing the risk of the second end of the power connection terminal 22 contacting the liquid to be purified or the purified liquid, thereby reducing the risk of short circuit when the power lead end of the power connection terminal 22 is connected to electricity, and improving the safety and reliability of the purification device in use; the purification assembly 20 is arranged in the first cavity 03 formed by the first shell 10, which facilitates improving the anti-interference and anti-pollution capabilities of the purification assembly 20, thereby improving the reliability of the purification device.

[0029] In other embodiments, the first sealing member is arranged in the power lead through hole, and the second end of the power connection terminal passes through the first sealing member. The first sealing member can seal the inner side wall of the power lead through hole and the outer peripheral wall of the power connection terminal, thereby isolating the second end of the power connection terminal from the liquid in the first cavity. This arrangement can reduce the risk of the liquid contacting the second end of the power connection terminal, thereby reducing the risk of electrode short circuit, and improving the safety and reliability of the purification device in use.

[0030] Optionally, the power lead through hole 02 is located on the side of the purification body 21 away from the liquid lead through hole 01.

[0031] In one application scenario, the power lead through hole 02 and the liquid lead through hole 01 are arranged at the two end portions of the first shell 10, that is, the power lead through hole 02 is located on the side of the purification body 21 away from the liquid lead through hole 01.

[0032] This arrangement facilitates better water and electricity separation, reduces the risk of the second end of the power connection terminal 22 contacting the liquid to be purified or the purified liquid, thereby reducing the risk of electrode short circuit, and improving the safety and reliability of the purification device in use.

[0033] In other embodiments, the electric lead-through hole is arranged at one end of the first shell, and the liquid lead-through hole is arranged at a side of the first shell; in other embodiments, the liquid lead-through hole is arranged at one end of the first shell, and the electric lead-through hole is arranged at a side of the first shell; in other embodiments, the liquid lead-through hole includes a water inlet hole and a water outlet hole, and the electric lead-through hole, the water inlet hole, and the water outlet hole are arranged at two ends and a side, for example, the electric lead-through hole is arranged at one end, the water inlet hole is arranged at the other end, and the water outlet hole is arranged at the side; for another example, the electric lead-through hole is arranged at the side, the water inlet hole is arranged at one end, and the water outlet hole is arranged at the other end, and the like, which will not be described here again. Such an arrangement facilitates the separation of the electric lead-through hole and the liquid lead-through hole.

[0034] Optionally, in other embodiments, as shown in FIGS. 1, 2, and 3, the electric lead-through hole 02 and the liquid lead-through hole 01 are arranged at two ends of the first shell 10, the first sealing member 30 includes a sealing ring 31, and the purification assembly 20 further includes a first sealing end cover 23, the purification body 21 is mounted on a side of the first sealing end cover 23 close to the liquid lead-through hole 01, an outer side wall of the first sealing end cover 23 is sealingly arranged with an inner wall of the first cavity 03 through the sealing ring 31, and a second end of the electric terminal 22 is penetratingly arranged in the first sealing end cover 23 and sealingly arranged with the first sealing end cover 23.

[0035] In the above arrangement, the purification body 21 is mounted on a side of the first sealing end cover 23 close to the liquid lead-through hole 01, that is, the first sealing end cover 23 is arranged on a side of the purification body 21 away from the liquid lead-through hole 01 and close to the electric lead-through hole 02, so that the liquid lead-through hole 01 and the electric lead-through hole 02 are arranged on two sides away from each other of the first sealing end cover 23; the second end of the electric terminal 22 is penetratingly arranged in the first sealing end cover 23 to extend to the electric lead-through hole 02 and further extend to outside of the first shell 10.

[0036] The above arrangement achieves a sealing effect through the first sealing end cover 23 and the sealing ring 31, thereby isolating the electric lead-through hole 02 and the liquid lead-through hole 01, and because the second end of the electric terminal 22 is penetratingly arranged in the first sealing end cover 23, the second end of the electric terminal 22 and the liquid in the first cavity 03 are isolated, which facilitates a better sealing effect; and the first sealing end cover 23 can also support the purification body 21, for example, in an application scenario, the purification body 21 and the first sealing end cover 23 are arranged in sequence along the direction of gravity; further, such an arrangement facilitates production and assembly.

[0037] Optionally, the first sealing member 30 includes two sealing rings 31 for sealingly connecting an outer side wall of the first sealing end cover 23 and an inner wall of the first cavity 03 to further improve the sealing effect.

[0038] Optionally, the power terminal and the first sealing end cover can be sealed by a sealing glue or a sealing ring, or the outer side wall of the first sealing end cover and the inner wall of the first cavity can be sealed by a sealing glue, and of course, other conventional sealing methods can also be used for sealing, which will not be described here.

[0039] Optionally, in other embodiments, the first sealing member can also include a sealing glue or other conventional sealing structures, which will not be described here.

[0040] Optionally, referring to FIGS. 1 and 2, the power lead-through hole 02 and the flow lead-through hole 01 are respectively arranged at the two end portions of the first shell 10, the outer side wall of the purification body 21 is arranged in a spaced manner with the inner wall of the side portion of the first shell 10, forming a first flow channel 010, and the first flow channel 010 is in communication with the flow lead-through hole 01.

[0041] In the first cavity 03, the first flow channel 010 is in communication with the purification flow channel of the purification body 21 and the flow lead-through hole 01. For example, in an application scenario, the liquid to be purified can flow into the first flow channel 010 through the flow lead-through hole 01, and then enter the purification flow channel of the purification body 21 through the first flow channel 010. After the liquid in the purification device is purified, the liquid can flow out of the purification flow channel of the purification body 21 to the flow lead-through hole 01, and then flow out of the purification device.

[0042] The power lead-through hole 02 and the flow lead-through hole 01 are respectively arranged at the two end portions of the first shell 10, which facilitates water and electricity separation, and reduces the risk of contact between the liquid to be purified and the second end of the power terminal 22. The outer side wall of the purification body 21 is arranged in a spaced manner with the inner wall of the side portion of the first shell 10, which facilitates the formation of the first flow channel 010, and can facilitate the flow of the liquid in the purification device, and can facilitate the more uniform flow of the liquid led by the flow lead-through hole 01 into the purification body 21, thereby improving the purification efficiency.

[0043] In other embodiments, the liquid to be purified can flow into the purification body through the flow lead-through hole and the first flow channel, and the purified liquid can flow out of the flow lead-through hole through the first flow channel.

[0044] In other embodiments, the first flow channel can not be provided, and the liquid to be purified can directly flow into the purification body through the water inlet hole.

[0046] Wherein, the tube body 211 provides support for the electrode assembly 212; as shown in FIG. 9, FIG. 10, the electrode assembly 212 is wound outside the tube body 211 and forms a purification flow channel extending along the circumference of the tube body 211, that is, the purification flow channel is wound outside the tube body 211 and extends along the circumference of the tube body 211, forming a spiral purification flow channel, which can effectively reduce the space occupied by the purification body 21, and the winding design can increase the length of the purification flow channel and improve the purification effect; further, the drainage through hole 01 comprises a water inlet through hole 012 and a water outlet through hole 011, the water inlet through hole 012 and the water outlet through hole 011 are designed separately, which is convenient for forming a one-way flow channel, reducing the risk of pollution of the purified liquid by the liquid to be purified, and improving the purification effect; further, one end of the purification flow channel is in communication with the water outlet through hole 011 through the first through hole 05 of the tube body 211 and the second cavity 04 of the tube body 211 in turn, and the other end is in communication with the water inlet through hole 012, that is, the second cavity 04 of the tube body 211 is used as a flow channel for liquid flow, which not only can reduce the number of components and simplify the structure, but also is convenient for guiding the purified liquid into the water outlet through hole 011 and separating the water inlet through hole 012 and the water outlet through hole 011; further, the first through hole 05 is arranged on the side wall of the tube body 211, which is more convenient for realizing the communication between the first through hole 05 and the purification flow channel wound outside the side wall of the tube body 211, and is convenient for flow guiding.

[0047] In an application scenario, the liquid to be purified flows into the other end of the above-mentioned purification flow channel through the water inlet through hole 012 and flows into the purification flow channel for purification, the purified liquid flows to the first through hole 05 through one end of the above-mentioned purification flow channel, and then flows into the second cavity 04 which is in communication with the first through hole 05, the liquid flows out of the water outlet through hole 011 at the open end of the second cavity 04, and then flows out of the first shell 10.

[0048] Optionally, the outer side wall of the electrode assembly 212 wound outside the tube body 211 is arranged in a spaced manner with the inner wall of the side of the first shell 10 to form the first flow channel 010.

[0049] In an application scenario, the liquid to be purified can flow into the first flow channel 010 through the water inlet through hole 012, and then enter the purification flow channel of the purification body 21 through the first flow channel 010. The purified liquid can directly flow out to the water outlet through hole 011 through the other end of the purification flow channel of the purification body 21, and then flow out of the purification device.

[0050] In other embodiments, the water inlet through hole described above can be used as a water outlet through hole, and the water outlet through hole is used as a water inlet through hole. Specifically, the liquid to be purified reaches the second cavity of the pipe body through the water inlet through hole, and then flows into the purification flow channel through the first through hole at one end of the purification flow channel, and then flows into the purification flow channel for purification. The purified liquid flows to the water outlet through hole through the other end of the purification flow channel, and then flows out of the first shell.

[0051] Optionally, the pipe body 211 forms a plurality of first through holes 05. The plurality of first through holes 05 facilitate to improve the uniformity of the flow between the purification flow channel and the second cavity 04, and can improve the liquid conduction speed between the purification flow channel and the second cavity 04, thereby improving the purification efficiency.

[0052] In an application scenario, the liquid to be purified reaches the other end of the purification flow channel through the water inlet through hole 012 and flows into the purification flow channel for purification. The purified liquid flows to the first through hole 05 through one end of the purification flow channel, and then flows into the second cavity 04 connected with the first through hole 05. The plurality of first through holes 05 facilitate to improve the speed of the liquid entering the second cavity 04, thereby improving the purification efficiency.

[0053] In another application scenario (not shown in the figure), the liquid to be purified reaches the second cavity of the pipe body through the water inlet through hole, and then flows into the purification flow channel through the first through hole at one end of the purification flow channel. The plurality of first through holes facilitate to make the liquid to be purified flow into the purification flow channel more uniformly, thereby improving the uniformity of the liquid distribution in the purification flow channel, and thus improving the purification efficiency.

[0054] Optionally, as shown in FIG. 6, the pipe body 211 is provided with a second through hole 06 near one end of the water outlet through hole 011. The second through hole 06 is provided as an opening of the second cavity 04, and the second cavity 04 is used to connect the purification flow channel and the water outlet through hole 011.

[0055] The second through hole 06 is provided as an opening of the second cavity 04, so that the second cavity 04 can be used to connect the purification flow channel and the water outlet through hole 011, thereby reducing the risk of contamination of the purified liquid by the liquid to be purified, for example, reducing the risk of contamination of the purified liquid by the liquid to be purified entering the second cavity 04 through the end of the pipe body 211 away from the water outlet through hole 011.

[0056] In some embodiments (not shown in the figures), a sealing structure such as a sealing member can be used to seal the end of the tube body away from the water outlet through hole to seal the end of the second cavity away from the water outlet through hole, so that the second cavity is used to communicate the purification flow channel with the water outlet through hole. Alternatively, the water outlet through hole and the water inlet through hole can be interchangeable, which will not be described here.

[0057] In some embodiments (not shown in the figures), the second cavity communicates with the water outlet through hole through the second through hole, which facilitates the concentration of the liquid flowing into the second cavity after purification to the water outlet through hole, facilitating the flow concentration.

[0058] In other embodiments, the tube body is provided through the water outlet through hole near the drainage through hole, and the outer peripheral wall of the tube body is sealingly arranged with the inner side wall of the water outlet through hole, so that the second through hole of the tube body can directly communicate with the external space, i.e. the second through hole can directly serve as the water outlet through hole.

[0059] Optionally, the electrode assembly 212 includes at least two electrode sheets 2121 with opposite polarities.

[0060] The electrode sheets 2121 are powered, and a capacitor is formed between adjacent electrode sheets 2121. The ions in the liquid are adsorbed by using the capacitor principle, so as to achieve the purpose of deionization to purify the liquid; and the ions adsorbed by the electrode sheets 2121 can also be desorbed and enter the purification flow channel to be carried away by the power-off setting, realizing desorption regeneration.

[0061] Optionally, as shown in FIG. 9, the end of the electrode sheet 2121 of the electrode assembly 212 away from the tube body 211 extends towards the electricity leading through hole 02 to form a tab 2123, and the tabs 2123 of at least two adjacent electrode sheets 2121 wound on the tube body 211 are arranged at intervals along the circumference of the tube body 211; the first end of the electricity connection terminal 22 is connected with the tab 2123.

[0062] It should be noted that the tabs 2123 of at least two adjacent electrode sheets 2121 are arranged at intervals along the circumference of the tube body 211, which means that the tab 2123 of at least one positive electrode is arranged at an interval with the tab 2123 of at least one negative electrode.

[0063] Specifically, as shown in FIGS. 9 and 10, the end of the electrode sheet 2121 away from the tube body 211 forms a tab 2123, and after winding, the tabs 2123 of at least two adjacent electrode sheets 2121 are arranged at intervals along the circumference to reduce the risk of contact short circuit of the tabs 2123 of the at least two adjacent electrode sheets 2121; the tab 2123 of the electrode sheet 2121 extends towards the electricity leading through hole 02 to facilitate the convenience of electrical connection between the electricity connection terminal 22 and the tab 2123, and thus facilitate the power supply of the electrode sheet 2121 by the electricity connection terminal 22.

[0064] Optionally, as shown in FIG. 9 and FIG. 10, the electrode assembly 212 includes a plurality of electrode sheets 2121. The tabs 2123 can be pre-set on the electrode sheets 2121, and then the plurality of electrode sheets 2121 with the tabs 2123 can be wound on the tube body 211. This arrangement can reduce the subsequent process steps of connecting the tabs 2123, and reduce the complexity of the production process.

[0065] In an application scenario, the specifications of the plurality of electrode sheets 2121 can be the same, and the tabs 2123 of the plurality of electrode sheets 2121 can be arranged at the same position. Therefore, by arranging the adjacent two electrode sheets 2121 to be offset along the circumferential direction of the tube body 211, the tabs 2123 of the adjacent two electrode sheets 2121 can be arranged to be spaced along the circumferential direction of the tube body 211 after winding. This facilitates assembly and mass production, and can reduce production complexity and improve production standardization.

[0066] In other embodiments, the specifications of the plurality of electrode sheets can be the same, but the positions of the tabs can be different. The tabs of the positive electrode and the tabs of the negative electrode can be arranged to be spaced and offset after winding, and the specific arrangement is not limited.

[0067] Optionally, as shown in FIG. 10, the plurality of electrode sheets 2121 can be arranged to be uniformly offset along the circumferential direction of the tube body 211 near the end of the tube body 211.

[0075] The plurality of electrode sheets 2121 and the plurality of isolation nets 2122 are alternately stacked, the polarity of adjacent electrode sheets 2121 is opposite, and the isolation net 2122 is arranged between adjacent electrode sheets 2121, the isolation net 2122 can isolate the electrode sheets 2121 with opposite polarity, that is, adjacent electrode sheets 2121 do not directly contact, reducing the risk of contact short circuit of adjacent electrode sheets 2121, and the arrangement of the isolation net 2122 also facilitates the formation of a gap between adjacent electrode sheets 2121, thereby forming a purification flow channel that can communicate with the first through hole 05 on the tube body 211, thereby facilitating the communication of the purification flow channel with the second cavity 04 through the first through hole 05, and facilitating the flow of liquid between the electrode sheets 2121, and the liquid forms a turbulent flow when flowing through the isolation net 2122; further, the plurality of electrode sheets 2121 and the plurality of isolation nets 2122 are alternately stacked and wound outside the side wall of the tube body 211, and a purification flow channel can be formed between adjacent electrode sheets 2121, and a purification flow channel can be formed on both sides of the electrode sheet 2121, thereby improving the utilization rate of the electrode sheet 2121; further, the plurality of electrode sheets 2121 are arranged in a circumferential direction near the end of the tube body 211, facilitating winding, and facilitating the distribution of one end of the plurality of purification flow channels in the circumferential direction of the tube body 211, improving the uniformity of the distribution, and facilitating the communication of one end of the plurality of purification flow channels with the first through hole 05, thereby improving the flow of the purification flow channel to the second cavity 04, and thereby improving the purification efficiency; the first end of the electrical connection terminal 22 is connected with the electrode sheet 2121, facilitating the power supply to the electrode sheet 2121.

[0076] In an application scenario, the electrode sheet 2121 is powered, a capacitor is formed between adjacent electrode sheets 2121, and the ions in the liquid are adsorbed by using the capacitor principle, thereby achieving the purpose of deionization to purify the liquid; the ions adsorbed by the electrode sheet 2121 can also be desorbed and enter the purification flow channel to be carried away by power-off setting, realizing desorption regeneration.

[0077] It should be noted that the number of electrode sheets 2121 and isolation nets 2122 is not limited, and a corresponding purification flow channel can be formed. For example, four electrode sheets 2121 and four isolation nets 2122 can be alternately stacked to increase the number of purification flow channels, thereby improving the purification efficiency while reducing the size of the purification assembly 20.

[0078] Optionally, the pipe body 211 forms a plurality of first through holes 05, and the plurality of electrode sheets 2121 and the plurality of isolation nets 2122 can form a plurality of purification flow channels. The plurality of first through holes 05 are arranged at intervals, and one end of each purification flow channel can communicate with the plurality of first through holes 05, thereby improving the uniformity of liquid flow and the flow speed between the purification flow channel and the second cavity 04, and further improving the purification efficiency.

[0079] Optionally, in other embodiments, as shown in FIGS. 8 and 10, the plurality of electrode sheets 2121 near the end of the pipe body 211 and the plurality of isolation nets 2122 near the end of the pipe body 211 are arranged in a circumferential staggered manner; the end of the isolation net 2122 is in contact with the outer circumferential wall of the pipe body 211, and the isolation net 2122 isolates the pipe body 211 and the electrode sheet 2121.

[0080] Specifically, the electrode sheet 2121 is sandwiched by the two adjacent isolation nets 2122, and the electrode sheet 2121 does not directly contact the pipe body 211, so that the end of the electrode sheet 2121 near the pipe body 211 does not directly contact the pipe body 211, i.e., the isolation net 2122 forms a gap between the end of the electrode sheet 2121 near the pipe body 211 and the pipe body 211, which facilitates the purification flow channel to communicate with the first through hole 05 on the pipe body 211 through the gap, thereby realizing the communication between the purification flow channel and the second cavity 04. In an application scenario, before winding, the plurality of electrode sheets 2121 and the plurality of isolation nets 2122 are alternately stacked, the plurality of isolation nets 2122 near the end of the pipe body 211 are staggered to form a gradient surface, and the end of the electrode sheet 2121 near the pipe body does not protrude from the end of the adjacent isolation net 2122. During winding, the winding starts from one end of the isolation net forming the gradient surface, and the gradient surface is arranged to face the pipe body 211 during winding, thereby enabling the end of the electrode sheet 2121 near the pipe body 211 to be lapped on the side of the adjacent isolation net 2122 away from the pipe body 211 on the side of the electrode sheet 2121 near the pipe body 211, i.e., the isolation net 2122 isolates the pipe body 211 and the electrode sheet 2121, so that the electrode sheet 2121 does not directly contact the pipe body 211.

[0081] The plurality of electrode sheets 2121 are arranged in a circumferential direction near the end of the pipe body 211 and the plurality of isolation nets 2122 are arranged in a circumferential direction near the end of the pipe body 211, which facilitates winding and facilitates the distribution of one end of the purification flow channel along the circumferential direction of the pipe body 211, improves the uniformity of distribution, and further improves the liquid flow speed between the purification flow channel and the second cavity 04; further, the staggered arrangement facilitates the end of the isolation net 2122 to be in contact with the outer circumferential wall of the pipe body 211, facilitates the electrode sheet 2121 near the end of the pipe body 211 to be lapped on the side of the adjacent isolation net 2122 away from the pipe body 211 on the side of the electrode sheet 2121 near the pipe body 211, and further facilitates the position of the electrode sheet 2121 to be fixed by the isolation net 2122, without the need to set an additional connection process on the electrode sheet 2121 to connect with the pipe body 211, which can reduce the interference to the electrode sheet 2121 and can make the electrode sheet 2121 not directly contact with the pipe body 211, improving the protection of the electrode sheet 2121; further, the isolation net 2122 is arranged between adjacent electrode sheets 2121, which facilitates to improve the isolation effect of the isolation net 2122 on the electrode sheet 2121, facilitates to reduce the risk of contact short circuit between the plurality of electrode sheets 2121, and improves the reliability of the purification device.

[0082] Optionally, the plurality of isolation nets 2122 can be set to have the same specification size, or the plurality of electrode sheets 2121 can be set to have the same specification size, which can reduce the production complexity and improve the production standardization.

[0083] Optionally, the pipe body 211 forms a plurality of first through holes 05 arranged at intervals along the circumferential direction, which facilitates the one end of the plurality of purification flow channels arranged along the circumferential direction to be in conduction with the corresponding first through hole 05.

[0084] Optionally, as shown in FIGS. 8 and 10, the first staggered distance x between adjacent electrode sheets 2121 is determined by the circumferential length of the pipe body 211 and the number n of electrode sheets 2121. For example, when the pipe body 211 is a cylinder, the first staggered distance x should satisfy the relationship 1-1: x = πd / n …… 1-1

[0085] wherein d is the diameter of the pipe body 211. For example, if the diameter d of the pipe body 211 is 17 mm and the number n of electrode sheets 2121 is 4, the first staggered distance x should be 13.345 mm.

[0086] This arrangement can achieve the uniform distribution of the electrode sheets 2121 near the end of the pipe body 211 along the circumferential direction of the pipe body 211, and further facilitates the plurality of purification flow channels formed by the plurality of electrode sheets 2121 to be uniformly distributed along the circumferential direction of the pipe body 211; further, it is also convenient to arrange the plurality of first through holes 05 to be uniformly distributed on the side wall of the pipe body 211, which not only facilitates the uniform flow of liquid into the second cavity 04, but also facilitates the processing of the pipe body 211 and the assembly of the electrode assembly 212, improving the assembly convenience and production standardization.

[0087] Optionally, the second dislocation distance between the adjacent isolation nets 2122 arranged along the circumference of the pipe body 211 can be set with reference to the first dislocation distance x, so as to make the electrode sheet 2121 not in direct contact with the pipe body 211, and improve assembly convenience and production standardization.

[0088] In some embodiments, the dislocation distance between the adjacent isolation nets 2122 and the electrode sheet 2121 along the circumference of the pipe body 211 can also be adjusted to further improve the isolation effect of the isolation net 2122 on the electrode sheet 2121 and the pipe body 211, and reduce the risk of direct contact between the electrode sheet 2121 and the pipe body 211.

[0089] For example, as shown in FIG. 8, the end of the electrode sheet 2121 close to the pipe body 211 is arranged along the circumference of the pipe body 211 with the end of the adjacent isolation net 2122 close to the pipe body 211 on the side of the electrode sheet 2121, and the dislocation distance between the two ends is a third dislocation distance y. The third dislocation distance y and the first dislocation distance x can satisfy the relationship 1-2: y > x / 2 …… 1-2

[0090] Such arrangement can improve the isolation effect of the isolation net 2122 on the pipe body 211 and the electrode sheet 2121, reduce the risk of direct contact between the electrode sheet 2121 and the pipe body 211, and thus improve the reliability of the purification flow channel.

[0091] In some embodiments, the second dislocation distance y can satisfy the relationship 1-3: y ≥ 5 mm …… 1-3

[0092] The third dislocation distance y is greater than 5 mm, which can better reduce the risk of direct contact between the electrode sheet 2121 and the pipe body 211, that is, the isolation net 2122 can form a gap between the end of the electrode sheet 2121 close to the pipe body 211 and the pipe body 211, so that the purification flow channel can communicate with the first through hole 05 on the pipe body 211 through the gap, and thus the purification flow channel can communicate with the second cavity 04; when the third dislocation distance y is equal to 5 mm, the risk of direct contact between the electrode sheet 2121 and the pipe body 211 can be reduced, and material waste can be reduced, the length of the purification flow channel can be increased, and the purification effect can be improved.

[0093] In some embodiments, the second dislocation distance y can be adjusted according to specific application scenarios, for example, it can also be 3 mm, 2 mm, etc., and the specific value is not limited.

[0095] That is, the second sealing end cover 25 and the first sealing end cover 23 are sealingly arranged at the two ends of the third cavity respectively, the first end of the electric terminal 22 is connected with the electrode assembly 212, and the second end of the electric terminal 22 passes through the first sealing end cover 23 to extend to the electric through hole 02 and then extend to the outside of the first cavity 03; wherein one end of the purification flow channel communicates with the second cavity 04 of the pipe body 211 through the first through hole 05 of the pipe body 211, and then communicates with the water outlet through hole 011; the other end of the purification flow channel communicates with the water inlet through hole 012 through the third through hole 07 of the second shell 24.

[0096] The beneficial effects of the above arrangement are that the arrangement of the second shell 24 facilitates to improve the protection of the electrode assembly 212; the second sealing end cover 25 and the first sealing end cover 23 are sealingly arranged at the two ends of the third cavity respectively, which can reduce the risk of liquid leakage from the two ends where the second sealing end cover 25 and the first sealing end cover 23 are located; the pipe body 211 passes through the second sealing end cover 25 at the end close to the drainage through hole 01, which facilitates to make the second cavity 04 communicate with the water outlet through hole 011 to guide the liquid to flow out of the second cavity 04.

[0100] In other embodiments, the above-mentioned water inlet through hole and water outlet through hole can be interchangeable, i.e., the original water inlet through hole is used as the water outlet through hole, and the original water outlet through hole is used as the water inlet through hole, which will not be described here.

The first direction is parallel to the axial direction of the third cavity.

[0102] This arrangement can reduce the risk of liquid flowing into the purification flow channel from the two ends arranged opposite in the first direction, thus facilitating the liquid to be purified by entering the purification flow channel through the third through hole 07, thereby increasing the flow distance of the liquid in the purification flow channel, and further improving the purification effect. Further, this arrangement can also reduce the risk of liquid in the purification flow channel directly flowing into the third cavity or the first cavity 03 from the two ends arranged opposite in the first direction, thus allowing the liquid in the purification flow channel to flow to the second cavity 04 through the first through hole 05 along the purification flow channel, thereby improving the purification efficiency and purification effect.

[0103] In some embodiments, the axial direction of the first shell 10, the axial direction of the second shell 24, the axial direction of the tube body 211, the axial direction of the second cavity 04, the axial direction of the first cavity 03, and the axial direction of the third cavity are all arranged parallel, the drainage through hole 01 and the electrical terminal 22 are arranged in the first direction, and are respectively arranged at the two end portions of the first shell 10 arranged in the first direction.

Therefore, the purified liquid can be collected in the second cavity 04 through the first through hole 05, and then flow to the water outlet through hole 011, thereby improving the collection effect and discharge efficiency of the purified liquid and reducing the risk of contamination of the purified liquid.

[0107] In other embodiments, the water inlet through hole can also be coaxially arranged with the second cavity, and the water outlet through hole can be arranged in the circumferential direction of the water inlet through hole, for example, the water outlet through hole surrounds the water inlet through hole, which will not be described here.

[0108] In some embodiments, the second end of the power connection terminal 22 extends in a direction parallel to the axial direction of the first housing 10 away from the first housing 10, facilitating electrical connection between the second end of the power connection terminal 22 and an external power supply device.

[0109] Optionally, as shown in FIG. 3, the first housing 10 includes a main body 11 and a cover 12, the main body 11 and the cover 12 together form the first cavity 03, the main body 11 includes an open end and a bottom end arranged opposite in the axial direction of the main body 11; the cover 12 is arranged on the open end, the water inlet through hole 012 and the water outlet through hole 011 are arranged on the cover 12, and the electric lead-through hole 02 is arranged on the bottom end; the second sealing end cover 25 is provided with a first connecting pipe 251 corresponding to the water outlet through hole 011, and at least part of the pipe body 211 passes through the first connecting pipe 251, so that the second cavity 04 and the water outlet through hole 011 are in communication, and the outer side wall of the pipe body 211 and the inner wall of the first connecting pipe 251 are sealingly arranged.

Therefore, the inner wall of the first connecting pipe 251 and the outer side wall of the pipe body 211 are sealingly arranged to reduce the risk of the liquid to be purified in the first cavity 03 directly flowing into the side of the purification flow channel close to the pipe body 211 through the gap between the first connecting pipe 251 and the pipe body 211, so that the liquid to be purified can flow into the purification flow channel from the side away from the second cavity 04. At the same time, it can also reduce the risk of the purified liquid on the side of the purification flow channel close to the pipe body 211 flowing into the first cavity 03 through the gap between the first connecting pipe 251 and the pipe body 211, thereby facilitating the purified liquid to flow into the second cavity 04 through the first through hole 05, and reducing the risk of the liquid to be purified contaminating the purified liquid.

[0117] Specifically, the purified liquid flows into the second adapter pipe 121 through the second cavity 04 of the pipe body 211, and then flows to the water outlet through hole 011 to flow out of the first shell 10.

[0118] The second adapter pipe 121 is arranged in the first cavity 03 and is sealingly arranged with the inner wall of the first cavity 03, which can reduce the risk of the to-be-purified liquid in the first cavity 03 flowing out to the water outlet through hole 011 through the gap between the outer wall of the second adapter pipe 121 and the inner wall of the first cavity 03.

[0123] In other embodiments, the cover body covers the open end, the main body separately forms the first cavity, the second sealing part is located in the water outlet through hole, and the inner wall of the water outlet through hole and the outer wall of the second adapter pipe are sealed. The end of the second adapter pipe away from the second cavity in the axial direction penetrates the water outlet through hole and extends to the outside of the first cavity, which can be used as a water outlet end. This can reduce the risk of the to-be-purified liquid in the first cavity flowing out from the gap between the inner wall of the water outlet through hole and the outer wall of the second adapter pipe.
