[0029] See also Figures 1 to 2 , Figure 1 It is a schematic diagram of the three-dimensional structure of the purification device provided in this application; Figure 2 yes Figure 1 sectional view in . The present application provides a purification device 100, which is used for a water purification device 1000. The purification device 100 includes a first shell 110, a purification component 120 and an exhaust pipe 130. The first shell 110 has a first cavity 111 and a liquid inlet 112 and a liquid outlet 113 connected to the first cavity 111. The purification component 120 is arranged in the first cavity 111. The first shell 110 serves as a carrier for accommodating components such as the purification component 120 and the exhaust pipe 130 in the purification device 100. The purification component 120 is used to purify the raw liquid entering the first cavity 111 through the liquid inlet 112 of the first shell 110, wherein the raw liquid can be seawater, industrial wastewater, tap water, etc., but is not limited thereto. The liquid purified by the purification component 120 is purified water, and the purified water can flow out from the liquid outlet 113. In some embodiments, the liquid outlet 113 is provided with a suction assembly (not shown). The suction assembly is used to increase the hydraulic pressure at the liquid outlet 113, thereby creating a negative pressure within the first cavity 111, and driving the gas within the first cavity 111 and the purified water to flow out of the liquid outlet 113. The suction assembly can be an electric pump, a pneumatic pump, an electromagnetic pump, etc., but is not limited thereto. It should be noted that providing a suction assembly at the liquid outlet 113 to increase the hydraulic pressure at the liquid outlet 113 is a conventional technical means used by those skilled in the art.

[0030] The present embodiment of the application does not limit the specific shape, size, material, etc. of the first housing 110, and can be reasonably designed according to actual needs. Optionally, the first housing 110 can adopt a variety of shapes and sizes, such as a cube, an elongated shape, a cylinder, a prism, etc. The specific shape and size of the first housing 110 can be determined based on the specific shape and size of the purification component 120, the application scenario of the water purification device 1000, and the water quality. The present embodiment of the application describes the first housing 110 as a cylindrical shape.

[0031] The purification assembly 120 includes a purification body 121 and a tube body 122. The purification body 121 is arranged in a winding manner outside the tube body 122 to form a purification flow channel 121a for liquid circulation and purification. The purification flow channel 121a is connected to the liquid inlet 112. The purification body 121 is used to purify the raw liquid entering the purification flow channel 121a from the liquid inlet 112. The tube body 122 extends along the axial direction of the first shell 110, and the purification body 121 extends along the axial direction of the tube body 122. By making the purification body 121 wound outside the tube body 122, the purification flow channel 121a of the purification body 121 is spirally arranged around the tube body 122 and extends along the axial direction of the tube body 122. Through such a structure, the total length of the purification flow channel 121a is longer and the flow area is wider, which can ensure a larger flow rate. At the same time, it ensures that the purification body 121 has a larger purification area, so that the entire purification process can be carried out continuously and efficiently, thereby improving the purification efficiency and purification effect of the purification device 100.

[0032] The tube body 122 is formed with a second cavity 1221 and a first through-hole 122a communicating with the second cavity 1221. The first through-hole 122a is also connected to the purification flow channel 121a of the purification body 121. The tube body 122 connects the purification flow channel 121a and the second cavity 1221 through the first through-hole 122a. The gas in the first cavity 111 and the purified water after purification by the purification body 121 can enter the second cavity 1221 through the first through-hole 122a.

[0033] The exhaust pipe 130 is disposed within the second cavity 1221 and extends axially along the tube body 122. The exhaust pipe 130 includes an air inlet end 131 and an air outlet end 132, which are axially opposed to each other. The air inlet end 131 communicates with the second cavity 1221, and the air outlet end 132 communicates with the liquid outlet 113, so that the exhaust pipe 130 can guide the gas within the first cavity 111 and the second cavity 1221, as well as the liquid within the second cavity 1221, to flow out of the liquid outlet 113. The air inlet end 131 of the exhaust pipe 130 can be flush with the end surface of the tube body 122 away from the liquid outlet 113, or can be located within the second cavity 1221 formed by the tube body 122. It is sufficient to ensure that the air inlet end 131 of the exhaust pipe 130 communicates with the second cavity 1221, and that the gas and purified water within the second cavity 1221 can enter the exhaust pipe 130 through the air inlet end 131. The exhaust end 132 of the exhaust pipe 130 can be sealed and docked with the liquid outlet 113 to isolate the liquid outlet 113 from the second cavity 1221 , preventing the purified water in the second cavity 1221 from directly flowing out to the liquid outlet 113 and affecting the exhaust effect of the exhaust pipe 130 .

[0034] The exhaust and purification principle of the purification device 100 is as follows: the raw liquid and gas to be purified flow into the liquid inlet 112, and enter the purification flow channel 121a under the action of the hydraulic pressure of the liquid outlet 113, and selectively flow along the circumferential and / or axial direction of the tube body 122 along the purification flow channel 121a toward the tube body 122. The purification body 121 can purify the raw liquid entering the purification flow channel 121a, and then the purified water and the gas in the purification flow channel 121a can enter the second cavity 1221 through the first through hole 122a under the action of hydraulic pressure and gravity, and enter the exhaust pipe 130 through the air inlet end 131 of the exhaust pipe 130, and finally flow out from the liquid outlet 113. By providing the exhaust pipe 130, the gas entering the purification device 100 can flow from the air inlet end 131 into the exhaust pipe 130 under the action of hydraulic pressure and gravity, and be discharged from the liquid outlet 113. At the same time, each area of ​​the purification flow channel 121a of the purification component 120 can be used for liquid to pass through, and the purification area of ​​the purification component 120 can be completely immersed in the liquid, so that the purification component 120 can fully exert its purification effect, thereby improving the utilization rate and service life of the purification component 120. It can be understood that the purification area of ​​the purification component 120 is the area where the purification body 121 can purify the raw liquid. The purification area at least includes the inside of the purification flow channel 121a and the surface of the purification body 121 used to form the purification flow channel 121a. Of course, it can also include the outer peripheral surface of the purification body 121 facing the shell and the two end faces of the purification body 121.

[0035] In some embodiments, the tube body 122 is formed with multiple groups of first liquid passages 1222 spaced apart along its circumference. Each group of first liquid passages 1222 includes multiple first through-holes 122a, and the multiple first through-holes 122a are spaced apart along the axial direction of the tube body 122. The purification body 121 is formed with multiple purification channels 121a, each of which corresponds to at least one group of first liquid passages 1222. By aligning each purification channel 121a with at least one group of first liquid passages 1222, purified water in the purification channel 121a, after being purified by the purification body 121, can quickly pass through the first through-holes 122a. This not only prevents congestion when the purified water passes through the first through-holes 122a, but also reduces water flow noise, thereby improving purification efficiency and user experience.

[0036] In some embodiments, a first flow channel 110 a is formed between the purification body 121 and the first housing 110 , communicating with the liquid inlet 112 and the purification flow channel 121 a . The first flow channel 110 a surrounds the outer periphery of the purification body 121 .

[0037] By arranging the first flow channel 110a around the periphery of the purification body 121, the raw liquid entering the first flow channel 110a from the liquid inlet 112 can enter the purification flow channel 121a along the circumference of the purification body 121 from multiple directions, thereby ensuring that the first flow channel 110a can pass a larger water flow rate, avoiding water congestion, and allowing the entire purification process to be carried out efficiently.

[0038] In addition, the first flow channel 110a and the purification flow channel 121a both extend along the axial direction of the tube body 122, and the length of the first flow channel 110a and the purification flow channel 121a along the axial direction of the tube body 122 is at least equal to the length of the purification body 121 in the axial direction, so that the purification body 121 can be completely immersed in liquid, so that the purification body 121 can fully exert its purification effect, thereby improving the utilization rate and service life of the purification body 121.

[0039] Please also refer to Figure 3 , Figure 3 This is a schematic diagram of the exploded structure of a portion of the purification device provided herein. The purification assembly 120 includes a second housing 123. The second housing 123 is sleeved over the purification body 121 and has a second through hole 123a. The second through hole 123a connects the first flow channel 110a and the purification flow channel 121a.

[0040] The second housing 123 is spaced apart from the first housing 110 to form a first flow channel 110a between the second housing 123 and the first housing 110. The first flow channel 110a is connected to the purification flow channel 121a through a second through hole 123a on the second housing 123.

[0041] The second shell 123 can be cylindrical and is used to be mounted outside the purification body 121 to enclose the purification body 121. The second shell 123 protects the purification body 121 and prevents the water flow from dispersing the purification body 121, thereby ensuring the uniformity of the purification flow channel 121a and preventing the flow area at different locations of the purification flow channel 121a from varying in width, which could cause large particles of impurities, suspended matter, and other solids to clog the purification flow channel 121a or rub the purification body 121 at locations with a narrower flow area.

[0042] The second housing 123 may be made of an insulating material to prevent a short circuit in the purification body 121. For example, the second housing 123 may be a rubber housing, a plastic housing, a ceramic housing, a glass housing, etc., but is not limited thereto.

[0043] In some embodiments, the second housing 123 is formed with multiple groups of second liquid passages 1231 spaced apart along its circumference. Each group of second liquid passages 1231 includes multiple second through-holes 123a, and the multiple second through-holes 123a are spaced apart along the axial direction of the second housing 123. Each purification channel 121a corresponds to at least one group of second liquid passages 1231. By aligning each purification channel 121a with at least one group of second liquid passages 1231, the raw liquid entering the first channel 110a from the liquid inlet 112 can quickly pass through the second through-holes 123a and enter the purification channel 121a. This not only prevents congestion of the raw liquid when passing through the second through-holes 123a, but also reduces water flow noise, thereby improving purification efficiency and user experience.

[0044] In some embodiments, the first housing 110 includes a main body 114 and a cover 115. The main body 114 includes an open end 1141 and a housing top 1142 disposed axially opposite to each other. The first cavity 111 is formed in the main body 114. The cover 115 covers the open end 1141.

[0045] The cover 115 can be detachably covered on the open end 1141 of the main body 114, thereby facilitating the removal of the purification component 120 to replace the purification component 120 disposed in the first cavity 111. The cover 115 and the open end 1141 can be fixed together by means of a threaded connection snap fastening, screw locking, bolt locking, bonding or magnetic adsorption. At the same time, a second sealing ring 152 can be provided between the cover 115 and the open end 1141 so that the second sealing ring 152 seals the cover 115 and the open end 1141 to prevent the raw liquid flowing into the first cavity 111 from the liquid inlet 112 from leaking out from between the cover 115 and the open end 1141. The second sealing ring 152 can be a rubber sealing ring, a silicone sealing ring, a sponge sealing ring or a wool felt sealing ring. The rubber sealing ring, the silicone sealing ring, the sponge sealing ring and the wool felt sealing ring all have good elasticity and a long service life. The second sealing ring 152 is elastic and ensures the sealing effect between the cover 115 and the open end 1141. The connection method between the cover 115 and the open end 1141 is not only simple, but also can ensure the sealing effect, simplifying the production process and making it more convenient for large-scale production.

[0046] The liquid inlet 112 and the liquid outlet 113 are provided on the cover body 115. The cover body 115 is arranged toward the bottom of the water purification equipment 1000, and the shell top 1142 is arranged toward the top of the water purification equipment 1000. When the water purification equipment 1000 is working, the raw liquid to be purified flows into the first flow channel 110a from the liquid inlet 112, flows into the purification flow channel 121a through the second through hole 123a of the second shell 123, and flows from the open end 1141 to the shell top 1142 to fill the entire first cavity 111, while pushing the gas to the side of the first cavity 111 close to the shell top 1142. Since the exhaust end 132 of the exhaust pipe 130 is connected to the liquid outlet 113, and the air inlet end 131 is connected to the second cavity 1221, the hydraulic pressure at the air inlet end 131 of the exhaust pipe 130 is maximized inside the purification device 100. Driven by gravity and the hydraulic pressure of the air inlet end 131, the gas on the side of the first cavity 111 close to the shell top 1142 flows into the second cavity 1221 through the first through hole 122a of the tube body 122, and enters the exhaust pipe 130 through the air inlet end 131, and finally flows along the exhaust pipe 130 to the liquid outlet 113 for discharge, so that the gas will not gather on the side of the first cavity 111 close to the shell top 1142 and be unable to be discharged, thereby allowing water to enter the side of the first cavity 111 close to the shell top 1142 to immerse the purification body 121, thereby improving the utilization rate and service life of the purification body 121.

[0047] Please also refer to Figure 4 , Figure 4: This is a partial structural diagram of the exhaust pipe of the purification device provided in this application. The exhaust end 132 of the exhaust pipe 130 is formed with a first connecting portion 1321, a support portion 1322, and a second connecting portion 1323 arranged in sequence. Among them, the first connecting portion 1321 is located at the end of the support portion 1322 close to the air inlet end 131, and the second connecting portion 1323 is located at the end of the support portion 1322 close to the liquid outlet 113. The outer diameter of the second connecting portion 1323 is smaller than the outer diameter of the support portion 1322, and the outer diameter of the second connecting portion 1323 is greater than or equal to the outer diameter of the support portion 1322. The first connecting portion 1321, the support portion 1322 and the second connecting portion 1323 all have a structure with a central hole, so that the exhaust pipe 130 can be connected to the liquid outlet 113. The central hole of the first connecting portion 1321, the central hole of the support portion 1322 and the central hole of the second connecting portion 1323 are coaxially arranged.

[0048] The first connecting portion 1321 is located within the second cavity 1221 and is sealedly connected to the tube body 122. This isolates the second cavity 1221 from the liquid outlet 113, preventing the purified water in the second cavity 1221 from flowing directly out of the liquid outlet 113 and affecting the exhaust efficiency of the exhaust pipe 130. A support portion 1322 extends from the first connecting portion 1321 along the circumference of the exhaust pipe 130, away from the exhaust pipe 130. The end of the tube body 122 near the liquid outlet 113 is supported by the support portion 1322. When installing the exhaust pipe 130 on the tube body 122, the air inlet end 131 can be extended from the end of the tube body 122 near the cover 115 into the tube body 122. When the first connecting portion 1321 is inserted into the tube body 122 and the end of the tube body 122 near the liquid outlet 113 abuts the end of the support portion 1322 near the first connecting portion 1321, the exhaust pipe 130 is installed.

[0049] In some embodiments, the inner diameter of the first connecting portion 1321 can be larger than the inner diameter of the tube body 122. The first connecting portion 1321 can be a sealing plug with a certain elasticity, for example, a rubber plug, a silicone plug or other elastic plastic plug. A guide portion 1321a is formed at the end of the first connecting portion 1321 away from the support portion 1322. The outer diameter of the guide portion 1321a is smaller than the inner diameter of the tube body 122. The guide portion 1321a can extend into the tube body 122. The first connecting portion 1321 can shrink and enter the tube body 122 under the guidance of the guide portion 1321a and the extrusion of the tube body 122. When the end of the tube body 122 close to the liquid outlet 113 abuts against the side of the support portion 1322 close to the first connecting portion 1321, it indicates that the first connecting portion 1321 has completely entered the tube body 122. At this time, the first connecting portion 1321 restores its elastic deformation and fits tightly against the inner wall of the tube body 122, thereby being sealed and connected to the tube body 122. In some embodiments, the inner diameter of the first connecting portion 1321 can be smaller than or equal to the inner diameter of the tube body 122. In this case, a sealed connection can be achieved by threading the first connecting portion 1321 and the tube body 122. After the exhaust pipe 130 is installed, sealant can be injected into the abutment between the supporting portion 1322 and the tube body 122 to further enhance the isolation between the second cavity 1221 and the liquid outlet 113.

[0050] One end of the second connecting portion 1323 facing away from the supporting portion 1322 is docked with the liquid outlet 113 and is sealed with the cover body 115 to isolate the liquid inlet 112 and the liquid outlet 113, thereby separating the raw liquid flowing in from the liquid inlet 112 from the purified water flowing from the exhaust pipe 130 to the liquid outlet 113, preventing the raw liquid from flowing into the liquid outlet 113 through the space between the cover body 115 and the exhaust pipe 130, thereby contaminating the purified water, and at the same time preventing the purified water from flowing into the liquid inlet 112 through the space between the cover body 115 and the exhaust pipe 130 and mixing with the raw liquid, thereby wasting the purified water.

[0051] Please also refer to Figures 5 and 6 , Figure 5 This is a schematic structural diagram of an embodiment of a purification component of the purification device provided in this application; Figure 6It is a structural schematic diagram of another embodiment of the purification component of the purification device provided in this application. The purification body 121 includes a plurality of isolation nets 1211 and a plurality of electrode sheets 1212. The plurality of electrode sheets 1212 and the plurality of isolation nets 1211 are alternately stacked and wound around the tube body 122. A purification flow channel 121a is formed between the isolation net 1211 and the electrode sheets 1212. Among them, the ends of the plurality of electrode sheets 1212 close to the tube body 122 are staggered along the circumference of the tube body 122, so that the width of the purification flow channel 121a at one end close to the tube body 122 is wider, and the water flow can pass through the purification flow channel 121a close to one end of the tube body 122 at a relatively slow speed, and smoothly pass through the first through hole 122a. On the one hand, it can avoid the turbulent water flow causing greater noise, and on the other hand, it can also avoid the water flow blocking the first through hole 122a, effectively improving the purification efficiency and quiet effect of the purification device 100, thereby improving the user experience.

[0052] The isolation net 1211 is arranged between two adjacent electrode sheets 1212 to isolate the two adjacent electrode sheets 1212. The isolation net 1211 can be a mesh structure woven from an insulating material. The isolation net 1211 has a certain flexibility, which makes it easy to wind the isolation net 1211 around the tube body 122. The isolation net 1211 can be selected from super-hydrophobic insulating materials, or the surface of the isolation net 1211 facing the electrode sheets can be coated with a super-hydrophobic coating to enhance the isolation effect of the isolation net 1211. The specific material of the isolation net 1211 can be determined according to the specific circumstances. For example, the material of the isolation net 1211 can be polyimide (PI), polyester (PET), polytetrafluoroethylene (PTFE), rubber, silicone, etc., but is not limited to this.

[0053] In some embodiments, the ends of the plurality of electrode sheets 1212 proximate to the tube body 122 are staggered along the circumference of the tube body 122 with the ends of the plurality of isolation nets 1211 proximate to the tube body 122, and the ends of the isolation nets 1211 proximate to the tube body 122 are arranged in contact with the outer peripheral wall of the tube body 122. The ends of the electrode sheets 1212 proximate to the tube body 122 overlap the side of the corresponding isolation net 1211 facing away from the tube body 122 and are spaced apart from the tube body 122. For example, each isolation net 1211 has a first side surface 1211a and a second side surface 1211b that are arranged opposite each other. The end of the second side surface 1211b proximate to the tube body 122 contacts the outer peripheral wall of the tube body 122, and the electrode sheets 1212 overlap the first side surface 1211a of the corresponding isolation net 1211 and are spaced apart from the tube body 122. Through such a structure, the electrode sheet 1212 can be insulated from the tube body 122, so that the material of the tube body 122 is not restricted by the electrode sheet 1212. For example, the tube body 122 can be made of metal material. In addition, since the isolation net 1211 has a mesh structure, the isolation net 1211 will not block the first through hole 122a on the tube body 122, ensuring that the purified water in the purification channel 121a can smoothly pass through the first through hole 122a into the second cavity 1221.

[0054] The electrode sheets 1212 include positive electrode sheets 1212a and negative electrode sheets 1212b, which are arranged alternately. When the purification device 100 is in operation, an electrostatic field is formed between the positive electrode sheets 1212a and the negative electrode sheets 1212b, causing tiny particles entering the purification flow channel 121a with the raw liquid to be charged. Under the action of the electrostatic field, the charged tiny particles move toward the electrode sheets 1212 with the opposite charge and are adsorbed on the electrode sheets 1212. For example, under the action of the electrostatic field, tiny particles with positive charges move toward the negative electrode sheets 1212b and are adsorbed on the negative electrode sheets 1212b, while tiny particles with negative charges move toward the positive electrode sheets 1212a and are adsorbed on the positive electrode sheets 1212a, thereby purifying the raw liquid. The purification device 100 in the embodiment of the present application can at least remove visible impurities such as dust, dirt, metal, heavy metals, and complex invisible impurities such as bacteria and viruses in the raw liquid, and is suitable for occasions with high requirements for the quality of the purified water.

[0055] The electrode sheet 1212 has a tab 1213 formed on one side of the end facing away from the tube body 122 and facing away from the liquid outlet 113. The tabs 1213 of at least two adjacent electrode sheets 1212 wound around the tube body 122 are spaced apart along the circumference of the tube body 122.

[0056] The tabs 1213 are used for connecting to an external power source. By forming the tabs 1213 on the side of the end of the electrode sheet 1212 facing away from the tube body 122 and away from the liquid outlet 113, once the purification device 100 is installed, the tabs 1213 can be located at one end of the purification device 100, while the liquid outlet 113 and the liquid inlet 112 are located at the other end. This achieves separation between the liquid and the circuit, significantly preventing short circuits and improving safety. By spacing at least adjacent tabs 1213, short circuits between adjacent tabs 1213 of different polarity can be avoided. Furthermore, the process of connecting the tabs 1213 to the electrical connection terminals 160 for connecting to an external power source is facilitated, reducing the time required to connect the tabs 1213 to the electrical connection terminals 160 and improving connection efficiency.

[0057] The tabs 1213 can be formed on the electrode sheet 1212 in a pre-reserved manner, that is, the tabs 1213 are not provided on the electrode sheet 1212 after the purification body 121 is wound on the tube body 122, but are provided on the electrode sheet 1212 when the electrode sheet 1212 is produced. The tabs 1213 can be combined with the electrode sheet 1212 by a fixed connection or an integral molding method, wherein the fixed connection method can be welding, riveting, etc., but is not limited thereto. The tabs 1213 are formed on the electrode sheet 1212 in a pre-reserved manner, so that during the assembly process of the purification device 100, the process of externally connecting the tabs 1213 is reduced, thereby improving the assembly efficiency, and at the same time, it is also conducive to the large-scale production of the electrode sheet 1212.

[0058] Please also refer to Figure 7 , Figure 7 The figure is a schematic diagram of the exploded structure of a portion of the structure of the purification device provided in this application. The purification device 100 also includes a first end cap 141 and a second end cap 142. The first end cap 141 is disposed on the end of the purification assembly 120 that is close to the cover body 115. The second end cap 142 is disposed on the end of the purification assembly 120 that is away from the cover body 115, with the air inlet end 131 spaced apart from the bottom of the cover body 115. The purification assembly 120 is supported between the first end cap 141 and the second end cap 142, so that the purification assembly 120 can remain stable during operation to ensure the purification effect.

[0059] The inner sidewall of the first end cap 141 is in close contact with the end of the purification assembly 120 near the cover body 115, and the outer sidewall of the first end cap 141 is in close contact with at least a portion of the inner sidewall of the main body 114 near the open end 1141, so that the first end cap 141 is sealed between the purification assembly 120 and the main body 114. A sealant can be provided between the inner sidewall of the first end cap 141 and the purification assembly 120, and between the outer sidewall of the first end cap 141 and at least a portion of the inner sidewall of the main body 114 to improve the sealing effect, or glue can be injected.

[0060] The first end cap 141 is provided with a connecting tube 1411 corresponding to the liquid outlet 113. At least a portion of the exhaust pipe 130 is inserted through the connecting tube 1411 to connect with the liquid outlet 113. In some embodiments, the second connecting portion 1323 of the exhaust pipe 130 is inserted through the connecting tube 1411 to connect with the liquid outlet 113. The end of the connecting tube 1411 closest to the liquid outlet 113 abuts against the side of the support portion 1322 facing away from the second connecting portion 1323.

[0061] A second flow channel 110b is formed between the side of the first end cap 141 close to the liquid inlet 112 and the main body 114. The second flow channel 110b connects the liquid inlet 112 and the first flow channel 110a. In some embodiments, the side of the first end cap 141 close to the liquid inlet 112 is spaced apart from the main body 114 to form the second flow channel 110b, so that the second flow channel 110b extends along the axial direction of the main body 114. Since the first flow channel 110a is not only arranged around the periphery of the purification component 120, but also along the axial direction of the purification component 120, the axial extension direction of the second flow channel 110b coincides with that of the first flow channel 110a, so that the raw liquid flowing in from the liquid inlet 112 can smoothly pass through the junction of the second flow channel 110b and the first flow channel 110a, avoiding water congestion.

[0062] The inner sidewall of the second end cap 142 is in close contact with one end of the purification component 120 near the shell top 1142 of the main body 114, and the outer sidewall of the second end cap 142 is in close contact with at least a portion of the inner sidewall of the main body 114 near the shell top 1142, so that the second end cap 142 is sealed between the purification component 120 and the main body 114. The purification device 100 also includes a first sealing ring 151. The first sealing ring 151 is disposed between the second end cap 142 and the main body 114. The first sealing ring 151 is used to seal the second end cap 142 and the main body 114, thereby isolating the area between the side of the second end cap 142 facing the shell top 1142 and the shell top 1142 from the first cavity 111, preventing liquid in the first cavity 111 from seeping out from between the second end cap 142 and the main body 114 and wetting the electrical connection terminal 160, thereby effectively improving safety.

[0063] The first sealing ring 151 can be a rubber sealing ring, a silicone sealing ring, a sponge sealing ring, or a wool felt sealing ring. These sealing rings all have good elasticity and a long service life. The elasticity of the first sealing ring 151 effectively improves the sealing effect between the second end cap 142 and the main body 114.

[0064] The end of the tube body 122 facing the shell top 1142 abuts against the top wall of the second end cap 142, preventing the purified water and gas within the second cavity 1221 from flowing back into the purification flow channel 121a between the tube body 122 and the top wall of the second end cap 142. The air inlet end 131 is spaced apart from the top wall of the second end cap 142, that is, a gap is provided between the air inlet end 131 and the top wall of the second end cap 142, allowing the purified water and gas within the second cavity 1221 to flow through the gap between the air inlet end 131 and the second end cap 142 and enter the exhaust pipe 130 through the air inlet end 131 for discharge from the liquid outlet 113.

[0065] In some embodiments, the second end cap 142 is formed with a groove 1421 that protrudes toward the housing top 1142. At least a portion of the tube 122 is accommodated in the groove 1421, and the end of the tube 122 facing the housing top 1142 abuts against the top wall of the groove 1421, and the air inlet end 131 is spaced apart from the top wall of the groove 1421.

[0066] Please also refer to Figure 8 , Figure 8 yes Figure 1 A top view of the second end cap 142 is formed with a first opening 142a. The shell top 1142 is formed with a second opening 1142a corresponding to the first opening 142a. The purification component 120 also includes an electrical connection terminal 160. The electrode tab 1213 of the electrode sheet 1212 is connected to the first end 161 of the electrical connection terminal 160. The second end 162 of the electrical connection terminal 160 passes through the first opening 142a and the second opening 1142a and exits the first cavity 111. The second end 162 of the electrical connection terminal 160 is used to connect to an external power source.
