Description

Technical Field

[0001] This utility model relates to the field of electrolysis technology, and in particular to an electrolysis structure. Background Technology

[0002] An aqueous solution containing ozone and other oxidizing groups can be produced using water or an aqueous electrolyte as raw material through an electrolysis device. The ozone, oxygen atoms, and hydroxyl radicals generated by the electrolysis device can effectively kill bacteria and viruses, and therefore can be well applied to daily disinfection.

[0003] Existing electrolysis devices consist of arranged anodes and cathodes, or an anode, cathode, and a membrane sandwiched in between for proton exchange. Conductive terminals or contact-type power supply plates are connected to the electrode plates to achieve stable power supply. Furthermore, the casing has independent inlet and outlet caps forming a water channel. These are all essential components of an electrolysis device, making it difficult to reduce its size for application in small appliances or other scenarios requiring miniaturized electrolysis. Even applying existing electrolysis structures to small household appliances increases the overall size of the device, compromising its original portability and compact design, and failing to meet miniaturization requirements. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and to provide an electrolytic structure.

[0005] An electrolysis structure includes an outer shell and a plurality of electrolysis units disposed within the outer shell. Each electrolysis unit includes a first electrode, an electrolyte membrane, and a second electrode disposed sequentially. The outer shell is provided with an inlet and an outlet.

[0006] The first electrode is connected to a first conductive sheet, which is arranged in a direction parallel to the water inlet end. The second electrode is connected to a second conductive sheet, which is arranged in a direction parallel to the water outlet end.

[0007] In one embodiment, a main flow channel and a secondary flow channel are formed on the inner wall of the first electrode and / or the second electrode and / or the outer casing. The main flow channel is arranged along the direction of the water inlet end, and the first end of the secondary flow channel is connected to the end of the main flow channel near the water inlet end. The secondary flow channel is at least partially located near the first conductive sheet and / or the second conductive sheet.

[0008] In one embodiment, the second end of the secondary channel is connected to the end of the main channel near the outlet end.

[0009] In one embodiment, the width of the main channel gradually decreases in the direction away from the water inlet.

[0010] In one embodiment, the width of the main channel gradually decreases from the direction near the water inlet end to the direction away from the water inlet end, and the width of the main channel gradually decreases from the direction near the water outlet end to the direction away from the water outlet end.

[0011] In one embodiment, the water inlet and the water outlet are respectively located at opposite ends of the outer casing in the width or length direction.

[0012] In one embodiment, the water inlet and the water outlet are located at the upper or lower part of the outer casing, and the first conductive sheet and the second conductive sheet are respectively located at the lower or upper part of the outer casing.

[0013] In one embodiment, the first conductive sheet is connected to the side of the first electrode facing away from the electrolyte membrane.

[0014] In one embodiment, the first conductive sheet is connected to the side of the first electrode facing the electrolyte membrane, and the electrolyte membrane is offset from the first conductive sheet.

[0015] In one embodiment, the side of the first conductive sheet facing the first electrode has the main flow channel groove and the secondary flow channel groove.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] This invention provides an electrolysis structure that is miniaturized and easily applied in small electrical appliances and other products. Specifically, for example... Figure 1-3 As shown, Example 1:

[0026] The electrolysis structure includes: an outer shell 1 and an electrolysis unit 8 disposed within the outer shell 1. The electrolysis unit 8 includes a first electrode 81, an electrolyte membrane, and a second electrode 82 disposed sequentially. The outer shell 1 is provided with a water inlet 2 and a water outlet 3.

[0027] The first electrode 81 is connected to a first conductive sheet 4, which is arranged in a direction parallel to the water inlet end 2. The second electrode 82 is connected to a second conductive sheet 5, which is arranged in a direction parallel to the water outlet end 3.

[0028] In this embodiment, the arrangement of the electrical terminals is parallel to the direction of the inlet and outlet water ends 3. That is, the arrangement direction of the first conductive sheet 4 is the same as the water flow direction of the inlet water end 2, and the arrangement of the second conductive sheet 5 is the same as the water flow direction of the outlet water end 3. This avoids the electrical terminals occupying space in other directions (for example, the inlet and outlet water ends 3 are set along the width direction while the electrical terminals are arranged along the length direction), making the overall electrolysis structure smaller and more suitable for use in small, portable products, thus expanding the application scenarios.

[0029] It should be understood that the water inlet 2 and the water outlet 3 are respectively disposed on two different outer surfaces of the outer casing 1. For example, the water inlet 2 and the water outlet 3 are respectively disposed on two opposite sides in the width direction of the outer casing 1; or, the water inlet 2 and the water outlet 3 are respectively disposed on two opposite sides in the length direction of the outer casing 1; or, the water inlet 2 and the water outlet 3 are respectively disposed on two opposite sides in the thickness direction of the outer casing 1. Alternatively, the water inlet 2 and the water outlet 3 can be disposed on two non-opposing sides, for example, the water inlet 2 is disposed on one side in the width direction of the outer casing 1, and the water outlet 3 is disposed on one side in the width direction of the outer casing 1. Preferably, to minimize the overall electrolysis structure volume, the water inlet 2 and the water outlet 3 are respectively disposed on two opposite sides in the width or length direction of the outer casing 1, thereby effectively utilizing the thickness volume of the outer casing 1.

[0030] It should be understood that the width and length directions of the outer shell 1 mentioned above are the same as the width and length directions of the electrolysis unit 8, which are parallel to the electrode plate. The thickness direction of the outer shell 1 mentioned above is the same as the thickness direction of the electrolysis unit 8, which is perpendicular to the electrode plate.

[0031] Furthermore, it should be understood that one end of the conductive sheet is connected to the electrode, and the other end extends out of the electrolytic cavity formed outside the outer casing 1 to be electrically connected to the power supply component.

[0032] Preferred, such as Figure 1 and 3 As shown in Embodiment 2, the remaining structure is the same as in Embodiment 1. A main flow channel 6 and a secondary flow channel 7 are formed on the inner wall of the first electrode 81 and / or the second electrode 82 and / or the outer casing 1. The main flow channel 6 is arranged along the direction of the water inlet 2, that is, water enters the cavity of the outer casing 1 from the water inlet 2 and flows through the electrolysis unit 8. The main flow channel 6 is arranged on the direct flow path of the water (that is, the main flow path after entering from the water inlet 2). The first end of the secondary flow channel 7 is connected to the end of the main flow channel 6 near the water inlet 2, so that the water is guided and diverted from the main flow channel 6 to the secondary flow channel 7. The secondary flow channel 7 is at least partially disposed near the first conductive sheet 4 and / or the second conductive sheet 5. That is, for example, the secondary flow channel 7 is at least partially disposed near the connection between the first electrode 81 and the first conductive sheet 4, and the secondary flow channel 7 is at least partially disposed near the connection between the second electrolytic sheet and the second conductive sheet 5. Or, for example, the secondary flow channel 7 is at least partially disposed near the connection between the first electrode 81 and the first conductive sheet 4 or near the connection between the second electrode 82 and the second conductive sheet 5.

[0033] Depending on the positions of the first conductive sheet 4 and the second conductive sheet 5, the number of secondary flow channel grooves 7 can be one or more. For example, if the first conductive sheet 4 and the second conductive sheet 5 are both connected to the same side of the electrolysis unit 8, the number of secondary flow channel grooves 7 is one, and this secondary flow channel groove 7 is at least partially disposed on the side close to the first conductive sheet 4 and the second conductive sheet 5. Alternatively, if the first conductive sheet 4 and the second conductive sheet 5 are respectively connected to opposite sides of the electrolysis unit 8, the number of secondary flow channel grooves 7 is two, with one secondary flow channel groove at least partially disposed on the side close to the first conductive sheet 4, and the other flow channel groove at least partially disposed on the side close to the second conductive sheet 5. Depending on actual design needs, the number of secondary flow channel grooves 7 can be multiple; these will not be elaborated upon in this embodiment.

[0034] For example, the main flow channel 6 and the secondary flow channel 7 are formed on the first electrode 81, meaning that the main flow channel 6 and the secondary flow channel 7 are formed on the surface of the first electrode 81. Alternatively, the main flow channel 6 and the secondary flow channel 7 are formed on the second electrode 82, meaning that the main flow channel 6 and the secondary flow channel 7 are formed on the surface of the second electrode 82. Yet another example is that the main flow channel 6 and the secondary flow channel 7 are formed on the inner wall of the outer casing 1, meaning that the outer casing 1 has an electrolysis chamber for accommodating the electrolysis unit 8, and the main flow channel 6 and the secondary flow channel 7 are formed on the side wall of the electrolysis chamber.

[0035] It should be understood that the main flow channel 6 and the secondary flow channel 7 mentioned in this application do not constitute the entire electrolysis chamber or the entire water flow path, but are only part of the water flow path.

[0036] In this embodiment, water enters from the inlet 2 and flows through the electrolysis unit 8, entering the main flow channel 6. Part of the water is guided into the secondary flow channel 7 connected to the main flow channel 6. This prevents the formation of a dry flow area due to the water deviating from the main flow channel during rapid flow, which could lead to the electrode plates burning out. In this embodiment, water is continuously guided to the edge area through the secondary flow channel 7, allowing the water in the edge area to flow forward, preventing dry burning, extending electrode lifespan, and fully utilizing the effective electrolysis area of ​​the electrode surface to improve electrolysis efficiency. The connection point between the conductive sheet and the electrode plate is located away from the main flow channel; a dry water area at this point can prevent the heat generated at the connection point from being carried away. In this embodiment, water entering the main flow channel 6 and being guided to the secondary flow channel 7 quickly carries away the heat at the conductive sheet connection point, preventing heat accumulation and extending electrode lifespan.

[0037] In one embodiment, such as Figure 1 and Figure 3As shown, the second end of the secondary channel trough 7 is connected to the end of the main channel trough 6 near the outlet end 3. This allows the water guided to the secondary channel trough 7 to be guided back to the main channel direction, forming a continuous water passage, further preventing water stagnation and the formation of a waterless flow area, while also quickly removing the heat generated at the connection of the conductive sheet.

[0038] Regarding the flow channel structure of the electrolysis structure, in Example 3: the remaining structure is the same as in Example 2, except that the width of the main flow channel 6 gradually decreases towards the direction away from the inlet end 2. Therefore, when water enters the electrolysis chamber, the flow channel narrows after entering the main flow channel 6, causing the water pressure at the narrowing point to rise, forcing the water to flow into the secondary flow channel 7. At the same time, since the width of the outlet end 3 of the main flow channel 6 increases again, the narrowing of the flow channel during the process of water entering the middle of the main flow channel from the inlet end 2 increases the water velocity. The high velocity and low pressure create a low pressure / negative pressure. Therefore, the water is drawn back into the main flow channel 6 from the secondary flow channel 7 by the low pressure, thus forming a complete water flow path and avoiding water stagnation that would create a waterless flow area.

[0039] Regarding the flow channel structure of electrolytic structures, such as Figure 1 and Figure 3 As shown in Example 4: The remaining structure is the same as in Example 1. The second end of the secondary channel trough 7 is connected to the end of the main channel trough 6 near the outlet end 3. The width of the main channel trough 6 gradually decreases from the direction near the inlet end 2 to the direction away from the inlet end 2, and the width of the main channel trough 6 gradually decreases from the direction near the outlet end 3 to the direction away from the outlet end 3. That is, the width at both ends of the main channel trough 6 is greater than the width at the middle end. Therefore, when water enters the electrolysis chamber, the flow channel narrows after entering the main channel trough 6, causing the water pressure at the narrowing point to rise, forcing the water to flow into the secondary channel trough 7. At the same time, since the width of the outlet end 3 of the main channel trough 6 increases again, the narrowing of the flow channel during the process of water entering the middle of the main channel from the inlet end 2 increases the water velocity. The high velocity and low pressure form a low pressure / negative pressure. Therefore, the water is drawn back into the main channel trough 6 from the secondary channel trough 7 by the low pressure, thus forming a complete water flow path and avoiding water stagnation that would create a waterless flow area. Furthermore, the design of the two ends being wide and narrowing in the middle allows the inlet end 2 and the outlet end 3 to be reversed. When reversed, the negative pressure can guide the water from the secondary channel 7 back to the main channel 6, allowing the electrolysis structure to be adjusted according to actual conditions to expand its application scenarios.

[0040] Preferred, such as Figure 1 and Figure 3As shown in Embodiment 5: the rest of the structure is the same as in Embodiment 1. The inlet end 2 and the outlet end 3 are respectively disposed at opposite ends of the outer casing 1. That is, the inlet end 2 and the outlet end 3 are disposed in the same direction, that is, the inlet end 2 and the outlet end 3 are disposed in parallel, so that the water flow does not turn at the inlet / outlet end 3, which is more conducive to the smooth flow of water and the rapid transfer of products. For example, the inlet end 2 and the outlet end 3 are disposed in a straight line, or the inlet end 2 and the outlet end 3 are parallel and staggered in the straight direction. And since the first conductive sheet 4 is disposed in a direction parallel to the inlet end 2 and the second conductive sheet 5 is disposed in a direction parallel to the outlet end 3, it can be seen that the first conductive sheet 4 and the second conductive sheet 5 are disposed in parallel in the same direction. For example, the first conductive sheet 4 and the second conductive sheet 5 are arranged along a straight line; or the first conductive sheet 4 and the second conductive sheet 5 are parallel and staggered in the straight line direction; or the first conductive sheet 4 and the second conductive sheet 5 are both connected to the same end of the electrolysis unit 8, that is, ① the first conductive sheet 4 is connected to the side of the first electrode 81 near the water inlet 2, and the second conductive sheet 5 is connected to the side of the second electrode 82 near the water inlet 2, and the first conductive sheet 4 and the second conductive sheet 5 are arranged on both sides of the water inlet 2, or ② the first conductive sheet 4 is connected to the side of the first electrode 81 near the water outlet 3, and the second conductive sheet 5 is connected to the side of the second electrode 82 near the water outlet 3, and the first conductive sheet 4 and the second conductive sheet 5 are arranged on both sides of the water outlet 3; or the first conductive sheet 4 and the second conductive sheet 5 are respectively connected to opposite sides of the electrolysis unit 8. In this embodiment, the first end of the conductive sheet is connected to the electrode, and the second end of the conductive sheet extends out of the outer shell 1 and is disposed on the outside. That is, the first conductive sheet 4 and the second conductive sheet 5 are respectively disposed at opposite ends of the outer shell 1, and are the same ends as the water inlet 2 and the water outlet 3. This embodiment will not describe each detail. In this embodiment, given that the water inlet 2 and the water outlet 3 occupy the space on both sides of the outer shell 1, this structure allows the conductive terminals (i.e., the first conductive sheet 4 and the second conductive sheet 5) to effectively utilize the space area, avoiding occupying space in other directions. This results in a miniaturized overall electrolysis structure, making it more suitable for use in small, portable products and expanding application scenarios.

[0041] For example, the directions of the water inlet 2 and the water outlet 3 are perpendicular to the electrode plates of the electrolysis unit 8. Alternatively, the directions of the water inlet 2 and the water outlet 3 are parallel to the electrode plates of the electrolysis unit 8. When the directions of the water inlet / outlet 3 are parallel to the electrode plates of the electrolysis unit 8, the water inlet 2 and the water outlet 3 are connected to both sides of the width direction of the outer shell 1 (i.e., the direction parallel to the electrolysis unit 8). This effectively utilizes the overall thickness and volume, avoids increasing the overall thickness and volume due to vertical water inlet, and makes the overall electrolysis structure smaller. This is more conducive to its application in small, portable products, expanding its application scenarios.

[0042] Preferred, such as Figure 1-3 As shown in Example 6, the other structures are the same as in Example 1. The inlet end 2 and the outlet end 3 are respectively located at opposite ends of the outer casing 1 in the width or length direction. The first conductive sheet 4 and the second conductive sheet 5 are respectively located at opposite ends of the electrolysis unit 8 in the width or length direction. The first end of the conductive sheet is connected to an electrode, and the second end of the conductive sheet extends out of the outer casing 1 and is located externally. That is, the first conductive sheet 4 and the second conductive sheet 5 are respectively located at opposite ends of the outer casing 1 in the width or length direction, and are the same ends as the inlet end 2 and the outlet end 3. This structure can effectively utilize the thickness space and reduce the overall volume of the electrolysis structure.

[0043] Based on the above embodiment 6, further, as Figure 1-3 As shown in Embodiment 7: The outer casing 1 is divided into an upper part and a lower part. The water inlet 2 and the water outlet 3 are located at the upper or lower part of the outer casing 1. Specifically, the water inlet 2 and the water outlet 3 are located on the side of either the upper or lower part. The first conductive sheet 4 and the second conductive sheet 5 are correspondingly located at the lower or upper part of the outer casing 1. Specifically, the first conductive sheet 4 and the second conductive sheet 5 are opposite each other on the side of the other part (the upper part of the outer casing 1 is the upper part of the electrolysis unit 8, and the conductive sheet is connected to the upper part of the electrode and extends out of the outer casing 1). Therefore, when the water inlet 2 and the water outlet 3 are located on the side of the upper part of the outer casing 1, the first conductive sheet 4 and the second conductive sheet 5 are opposite to the side of the lower part of the outer casing 1; when the water inlet 2 and the water outlet 3 are located on the side of the lower part of the outer casing 1, the first conductive sheet 4 and the second conductive sheet 5 are opposite to the side of the upper part of the outer casing 1. In the structure of this embodiment, the water inlet 2 and the water outlet 3 are offset from the centerline of the electrode unit, or in other words, the electrode unit is offset from the main flow path of the water inlet / outlet 3. In this embodiment, this structure is designed to compress the overall volume of the electrolysis structure. It is arranged to ensure that the inlet / outlet ends 3 and the conductive sheets can be simultaneously positioned on opposite ends of the outer casing 1 in either the width or length direction. Because the inlet end 2 and outlet end 3 are offset from the centerline of the electrode unit, the electrode areas (including the conductive sheet connections) deviating from the main flow channel easily form non-flowing areas, preventing effective product transfer and leading to dry burning. Furthermore, heat accumulation at the conductive sheet connections reduces electrode lifespan. However, by setting up the main flow channel 6 and the secondary flow channel 7, some water is guided through the secondary flow channel 7 to the electrode areas deviating from the main flow channel and then flows back to the main flow channel. This solves the problem of non-flowing areas caused by flow channel deviation, effectively ensuring the operation of the electrolysis structure and improving its overall service life.

[0044] In this embodiment, the connection between the first conductive sheet 4 and the first electrode 81 and the connection between the second conductive sheet 5 and the second electrode 82 are located on the same side. The structure of this embodiment can make full use of the volume space of the overall structure, so that the overall electrolysis structure is miniaturized. The secondary flow channel 7 can pass through the position close to the first conductive sheet 4 and the second conductive sheet 5 at the same time, and quickly remove the heat generated at the two electrical terminals, making the flow channel design simpler.

[0045] Regarding the conductive sheet and electrode connection structure, in Embodiment 8: the remaining structure is the same as in Embodiment 2. The first conductive sheet 4 is connected to the side of the first electrode 81 facing away from the electrolyte membrane, and similarly, the second conductive sheet 5 is connected to the side of the second electrode 82 facing away from the electrolyte membrane. This allows water flowing over the electrode surface to quickly remove heat from the connection point between the first conductive sheet 4 and / or the second conductive sheet 5 near the secondary flow channel groove 7.

[0046] Regarding the conductive sheet and electrode connection structure, in Embodiment 9: the remaining structure is the same as in Embodiment 2, with the first conductive sheet 4 connected to the side of the first electrode 81 facing the electrolyte membrane, and the electrolyte membrane offset from the first conductive sheet 4. Similarly, the second conductive sheet 5 is connected to the side of the second electrode 82 facing the electrolyte membrane, and the electrolyte membrane offset from the second conductive sheet 5. In other words, the first conductive sheet 4 and / or the second conductive sheet 5 are disposed between the first electrode 81 and the second electrode 82, and the electrolyte membrane is disposed between the first electrode 81 and the second electrode 82, offset from the first conductive sheet 4 and / or the second conductive sheet 5. This embodiment's structure effectively saves the overall thickness of the electrolysis unit 8, resulting in a miniaturized overall electrolysis structure.

[0047] Based on Embodiment 9, further in Embodiment 10, the first conductive sheet 4 has the main flow channel 6 and the secondary flow channel 7 formed on the side facing the first electrode 81. That is, the first electrode 81 has the main flow channel 6 and the secondary flow channel 7 on the side facing the electrolyte membrane, and / or the second electrode 82 has the main flow channel 6 and the secondary flow channel 7 on the surface facing the electrolyte membrane. In this embodiment, water can enter between the electrode sheet and the electrolyte membrane through the main flow channel 6 formed by the first electrode 81 / second electrode 82. Water is continuously transported to the secondary flow channel 7, and the water in the area near the secondary flow channel 7 is pushed forward. During this process, the water forms a complete flow path, avoiding areas without water flow. While quickly removing heat from the connection points of the conductive sheets, it can fully wet the electrolyte membrane, increasing the water-receiving area of ​​the electrolyte membrane, thereby improving electrolysis efficiency. Furthermore, in a preferred embodiment, the two ends of the secondary flow channel 7 are respectively connected to the two ends of the main flow channel 6, allowing water to be quickly guided to the secondary flow channel 7 and then flow back to the main flow channel, improving the transfer efficiency of products and heat.

[0048] In a preferred embodiment, both surfaces of the first electrode 81 and / or the second electrode 82 are provided with a main flow channel 6 and a secondary flow channel 7 to further construct a water flow path, so that water can fully enter the edge area for reaction, make full use of the effective electrolysis area of ​​the electrode surface, and increase the water-receiving area of ​​the electrolyte membrane, thereby improving the electrolysis efficiency. At the same time, the constructed water flow path can achieve rapid heat dissipation.

[0049] In one embodiment, a first injection hole is provided at the end of the first conductive sheet 4 connected to the first electrode 81, and a second injection hole is provided at the end of the second conductive sheet 5 connected to the second electrode 82. By providing injection holes in the first conductive sheet 4 and the second conductive sheet 5, overflow of conductive adhesive can be prevented, allowing for a larger range of adhesive variation and solving the problem of conductive adhesive contaminating the effective electrolysis area as the conductive sheet slides. Furthermore, the injection process is easily mechanized, eliminating the need for a precision dispensing machine. The fixed opening area of ​​the injection hole ensures the contact area between the silver paste and the electrode, guaranteeing a high installation pass rate. Adhesive injection through the injection hole bonds the electrode sheet and the conductive sheet, resulting in a stronger bond structure. This reduces the contact sealing area while maintaining bonding strength, thereby increasing the effective utilization area of ​​the electrode surface. In other words, reducing the connection point area between the conductive sheet and the electrode sheet effectively increases the effective electrolysis area of ​​the electrode surface, further miniaturizing the electrolysis structure and making it suitable for small, portable products.

[0050] For example, the material of the first conductive sheet 4 and / or the second conductive sheet 5 is copper; or the first conductive sheet 4 and the second conductive sheet 5 are made of other conductive materials.

[0051] The electrode unit includes a first electrode 8161, an electrolyte membrane 63, and a second electrode 8262 arranged sequentially. The electrolysis unit 8 electrolyzes water at low pressure to produce water containing ozone, oxygen atoms, hydroxyl radicals, and other substances with oxidizing and bactericidal properties, which is then output to the user end through the outlet 3.

[0052] For example, the electrolyte membrane is a proton exchange membrane (PEM), which provides a hydrogen ion channel, allowing H+ generated at the anode to migrate to the cathode through the proton exchange membrane, thereby increasing the reaction rate and the product formation rate.

[0053] In one embodiment, the material of the first electrode 81 and / or the second electrode 82 is one of conductive silicon, conductive diamond, or elemental titanium, platinum, lead, tantalum, iridium, palladium, or their oxides. For example, the material of the first electrode 81 and / or the second electrode 82 is one of conductive silicon or conductive diamond. Alternatively, the material of the first electrode 81 and / or the second electrode 82 is one of elemental titanium, platinum, lead, tantalum, iridium, palladium, or their oxides. Furthermore, the material of the first electrode 81 and / or the second electrode 82 may be other conductive materials, which will not be elaborated in this embodiment. In a preferred embodiment, the first electrode 81 and the second electrode 82 are made of the same material, and electrode switching between the first electrode 81 and the second electrode 82 can be achieved by changing the current, thereby reducing the problem of scale such as calcium carbonate adhering to the electrode surface.

[0054] This utility model also provides an electrical appliance, including the electrolytic structure described above. For example, the electrical appliance is a water flosser, a mouthwash cup, a spray bottle, an electric comb, a nasal irrigator, etc., which will not be described in detail in this embodiment.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
