Description

Technical Field

[0001] This utility model belongs to the field of sanitary ware technology, and relates to smart toilets, specifically to a smart toilet seat that uses electrolyzed water for sterilization. Background Technology

[0002] With the rapid development of smart home technology, smart toilet seats, as an intelligent upgrade product that can be easily adapted to traditional toilets, are playing an increasingly important role in improving the quality of family life. Smart toilet seats significantly enhance the convenience, comfort, and technological feel of traditional toilets by integrating multiple functional modules such as washing, temperature control, drying, and seat heating. However, after prolonged use, bacteria and grime can easily grow in the flushing nozzles and internal water channels of traditional smart toilet seats. Without effective self-cleaning methods, this not only affects the user experience but may also pose a potential hygiene hazard.

[0003] To meet this market demand, smart toilet seat products on the market have introduced a variety of auxiliary sterilization technologies. Among them, the most common method is to use chemical disinfectants for flushing and sterilization. Although this solution can achieve sterilization to a certain extent, it still has many limitations in practical applications: First, (1) it requires manual and regular addition of chemical agents, which is cumbersome and has the risk of omission; (2) chemical agents are easy to adhere to the inner wall of the flushing part or other flow channel components, which may lead to pipe blockage, material aging or even corrosion of equipment structure and shorten product lifespan; (3) some chemical components are irritating to human skin and mucous membranes, which poses certain safety hazards, especially for children, the elderly or people with sensitive constitutions; (4) it requires the design of an independent chemical dosing water circuit and mixing device, which increases the complexity of the system structure and the manufacturing and maintenance costs.

[0004] As is known to those skilled in the art, the anolyte produced during water electrolysis exhibits excellent bactericidal and disinfection properties due to its high oxidation-reduction potential, and has broad application prospects. However, existing electrolysis devices often have the following two problems: (1) When the output is mixed, that is, when the cathode product and the anolyte are mixed together, the oxidation-reduction potential of the actual output electrolysis product often fails to meet expectations as the cathode product consumes the anolyte, and its bactericidal and disinfection effects cannot meet the requirements; (2) When the output is split, that is, when the cathode product and the anolyte are output separately, the oxidation-reduction potential of the output anolyte is guaranteed to avoid the consumption of the anolyte by the cathode product; however, at this time the cathode product is waste, and for small devices with limited water storage (such as smart toilet seats), frequent water replenishment will seriously affect its working efficiency. In addition, although the method of electrolyzing brine can avoid the above problems to a certain extent, this method requires users to replenish brine to the electrolysis chamber regularly, which is complicated and affects the user's convenience and overall experience.

[0005] Therefore, how to achieve thorough disinfection while minimizing user operation steps is a technical problem that urgently needs to be solved when applying water electrolysis devices to smart toilet seats. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a smart toilet seat that uses electrolyzed water for sterilization, so as to solve the technical problems of insufficient sterilization effect and resource waste in the existing toilet seats that use electrolysis.

[0007] To achieve the above-mentioned technical objectives, according to one aspect of this utility model: a smart toilet seat that utilizes electrolyzed water for sterilization is provided, comprising: a first water supply passage and a flushing part telescopically disposed on the toilet seat body, the first water supply passage being connected to the flushing part; an electrolysis module disposed on the first water supply passage; the electrolysis space of the electrolysis module being divided into a cathode chamber with a cathode and an anode chamber with an anode by a first separator, the inlet and outlet of the electrolysis space being disposed in the anode chamber, and the first separator being an ion channel for cations.

[0008] In this application, by setting up an electrolysis module, the water flowing out of the rinsing section is transformed from ordinary tap water into water carrying electrolysis products and having bactericidal ability. This not only disinfects the rinsing section but also effectively cleans the human body, saving the time required for additional sterilization processes in existing technologies.

[0009] In existing electrolysis modules, the anode and cathode chambers are separated by an ion exchange membrane when outputting cathode and anode products respectively. To prevent electrode dry-burning, inlets and outlets are provided at both chambers. However, due to the selectivity of ion exchange membranes, taking cation exchange membranes as an example, even if the raw water entering the cathode chamber participates in electrolysis at the cathode, the generated hydroxide ions cannot pass through the cation exchange membrane. Therefore, in this structure, some of the raw water entering the electrolysis space does not participate in electrolysis; it only dissolves the electrolysis products and prevents electrode dry-burning, resulting in a low conversion ratio between the electrolysis products and the actual influent volume.

[0010] The electrolysis module of this application has its inlet located only on one side of the anode chamber. Because the required electrolysis module is small, the amount of water carried by ions during their migration from the anode chamber to the cathode chamber is sufficient to prevent the electrodes from drying out, thus overcoming the technical biases of the prior art.

[0011] Based on this, compared with the traditional diversion method, most of the raw water entering the electrolysis space in this application can participate in electrolysis at the anode chamber, resulting in a higher conversion ratio between the required electrolysis products and the actual influent volume. Furthermore, the separation effect of the first separator reduces the consumption of anode products by cathode products. Therefore, the water flowing out of the rinsing section carries a higher concentration of electrolysis products, achieving the user's expectations in both cleaning the human body and disinfecting the rinsing section.

[0012] Furthermore, the smart toilet seat also includes a heating component, which is located upstream of the water inlet of the electrolysis module in the first water supply path.

[0013] Placing the heating element upstream of the electrolysis module's inlet ensures that the electrolyzed water output to the rinsing section not only has highly effective sterilization capabilities but also a comfortable rinsing temperature, significantly improving the user experience. However, if it's placed downstream of the electrolysis module's outlet, considering the more reactive anolyte products, they are more easily consumed under heating. Therefore, this structural configuration would actually fail to meet the user's disinfection needs.

[0014] Furthermore, the cathode chamber is provided with a hydrogen outlet, which connects the cathode chamber to the outside of the anode chamber; the first partition is provided with a gas check structure.

[0015] By setting up a gas check valve structure, hydrogen generated in the cathode chamber is prevented from diffusing into the anode chamber, reducing the consumption of anode products by cathode products and ensuring the required amount of electrolytic products output from the electrolysis module outlet. This, in turn, ensures the disinfection and cleaning capabilities of the water flow or mist output from the rinsing section for washing the human body or the rinsing section itself.

[0016] Furthermore, a first gap is provided between the first partition and the peripheral wall of the electrolysis space, and the cathode chamber and the anode chamber are connected through the first gap; the first partition is provided with a water-blocking structure.

[0017] By incorporating a water-blocking structure and placing the water inlet of the electrolysis module solely on one side of the anode chamber, the amount of water entering the cathode chamber is reduced. Due to the limited water volume, less hydrogen dissolves in the water within the cathode chamber, and the probability of gaseous hydrogen reacting with the liquid anode products when diffusing into the anode chamber through the first gap is low. Therefore, although this structure outputs electrolysis products in a mixed-flow manner, it still reduces the unnecessary consumption of anode products, ensuring a sufficient amount of the required electrolysis products output. This, in turn, guarantees the cleaning effect of the water flow or mist output from the rinsing unit on the human body and the disinfection and cleaning capabilities of the rinsing unit itself.

[0018] Furthermore, the anode is disposed adjacent to the first partition, and the area of ​​the anode is smaller than the area of ​​the first partition; a third gap is provided between the anode and the peripheral wall of the anode chamber, and / or a third gap is provided between the anode and the first partition; the third gap is connected to the first gap.

[0019] Considering that the continuous accumulation of hydrogen in the cathode chamber may cause a significant impact on the first separator, causing it to expand towards the anode chamber, this application positions the anode and the first separator relatively close to each other to support the first separator and limit its expansion towards the anode chamber. Furthermore, it is necessary to ensure that the area of ​​the anode is smaller than the area of ​​the first separator so that hydrogen ions generated at the anode can pass through the first separator via the shortest path to the cathode to continue participating in electrolysis, reducing the electrolysis voltage required for ion migration. On the other hand, a third gap can also be provided between the anode and the first separator, and / or between the anode and the peripheral wall of the anode chamber, to achieve communication between the cathode chamber and the anode chamber, ensuring the smooth discharge of hydrogen generated at the cathode.

[0020] Furthermore, a second gap is provided between the cathode and the first partition, the area of ​​the cathode is smaller than the area of ​​the first partition, and / or a second gap is provided between the cathode and the peripheral wall of the cathode chamber; the second gap is connected to the first gap.

[0021] The presence of a second gap between the cathode and the first separator indicates that the distance between them is close. Hydrogen ions generated at the anode enter the cathode chamber through the first separator and can directly participate in electrolysis at the cathode. Therefore, the electrolysis required to drive ion migration in this application requires a smaller voltage. On the other hand, when second gaps are provided between the cathode and the peripheral wall of the cathode chamber, and between the cathode and the first separator, the rate at which hydrogen diffuses into the anode chamber increases, reducing the impact on the first separator as its volume increases, and extending the service life of the first separator.

[0022] When the area of ​​the cathode is equal to the area of ​​the first separator, the water flowing into the cathode chamber cannot diffuse to the cathode chamber on the other side due to the obstruction of the cathode. In this case, only one side of the cathode participates in electrolysis, resulting in low utilization. Alternatively, when a second gap is provided between the cathode and the peripheral wall of the cathode chamber, although the cathode chambers on both sides of the cathode can be connected through the second gap, allowing water to participate in electrolysis at the cathode on the side away from the first separator, the diffusion rate of hydrogen to the cathode chamber on the other side is slow due to the size limitation of the second gap. Most of the hydrogen generated during electrolysis still accumulates between the first separator and the cathode, causing a significant impact on the first separator. In this application, the area of ​​the cathode is smaller than the area of ​​the first separator, allowing the water flowing into the cathode chamber to diffuse to the cathode chamber on the other side, improving the utilization rate of the cathode. At the same time, the increased space reduces the impact of hydrogen on the first separator, extending its service life.

[0023] Furthermore, the anode is at least part of the peripheral wall of the anode chamber, and the anode encloses or partially encloses the electrolyzed raw water in the anode chamber; the cathode chamber is fitted outside the anode chamber.

[0024] This application configures the peripheral wall of the anode chamber as the anode, which fully guarantees the electrolysis area when the volume of the electrolysis module is limited. On the other hand, under the inlet flow rate of daily water use, the water enters the electrolysis module in the form of turbulence. Under the action of the turbulent and irregular flow field, the water will continuously hit the anode surrounding it and participate in electrolysis. Therefore, the electrolysis efficiency of this application can also be guaranteed.

[0025] Furthermore, at least one water-blocking element is provided in the anode chamber to divide the initial water path between the inlet and outlet into several interconnected second flow paths, the width ratio of the second flow path to the initial water path being less than or equal to 0.5.

[0026] To improve electrode utilization, this application limits the width of the second flow path within the anode chamber using a water-blocking element. The water-blocking element guides the water flow, extending its path and ensuring sufficient coverage of the electrodes within the second flow path, thus improving electrode utilization. Consequently, the improved electrode utilization leads to higher output electrolysis product parameters, overcoming the technical deficiency of insufficient electrode utilization in existing technologies.

[0027] Furthermore, the smart toilet seat also includes a humidity-sensitive element. When water passes through the electrolysis module, the humidity-sensitive element controls the control circuit of the electrolysis module to conduct.

[0028] By setting a humidity-sensitive element, the control circuit of the electrolysis module is automatically turned on when water passes through the electrolysis module, and automatically turned off when water does not pass through the electrolysis module. This not only avoids dry burning of the electrolysis module, but also ensures the starting efficiency of the electrolysis module, thereby ensuring the cleaning ability of the water flow or water mist output from the rinsing section for the human body or the disinfection and cleaning ability of the rinsing section itself.

[0029] After adopting the above technical solution, this application has the following beneficial effects:

[0030] 1. The smart toilet seat of this application adopts an electrolysis module independently developed by the inventor, which transforms cleaning water into functional water with bactericidal ability. It not only meets the needs of daily cleaning and disinfection of the flushing part, but can also be used to clean the human body, avoiding the cumbersome operation of constantly replenishing bactericide.

[0031] 2. The smart toilet seat described in this application, by employing the electrolysis module, ensures that the output water flow is free of odor and harmful substances, and avoids the use of cleaning agents while ensuring sterilization. This solves the problem in the prior art that the use of bactericides to clean the flushing part easily generates harmful or odorous gases, and has significant practical application value.

[0032] 3. The smart toilet seat described in this application, by placing the heating component upstream of the water inlet of the electrolysis module, ensures that the water output from the flushing section has not only sterilization capabilities but also a suitable temperature, thereby further guaranteeing the user experience.

[0045] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0046] Smart toilet seats, as an intelligent upgrade of traditional toilets, integrate multiple functional modules such as washing, temperature control, drying, and seat heating, significantly improving convenience, comfort, and technological sophistication during use. They have become an important part of modern bathroom spaces. They not only meet users' basic needs for a high-quality life but also drive the development of home hygiene environments towards intelligence and health.

[0047] However, with the public's increasing demands for home hygiene and health protection, especially against the backdrop of frequent public health events and growing awareness of disease prevention, the physical rinsing and simple drying functions of traditional smart toilet seats are no longer sufficient to meet users' actual needs for efficient sterilization and deep cleaning of the flushing head and the entire internal water system. In particular, during prolonged use, bacteria and grime can easily accumulate in the flushing nozzle and internal water channels. Without effective self-cleaning mechanisms, this not only affects the user experience but may also become a potential hygiene hazard, even leading to the risk of cross-infection.

[0048] To meet this market demand, current smart toilet seat products generally incorporate various auxiliary sterilization technologies to improve product hygiene and safety. A common approach is to use chemical disinfectants for rinsing and sterilization. While this method can achieve a certain level of sterilization, it still has many limitations in practical application:

[0049] 1. Cumbersome operation and poor user experience: Chemical reagents need to be added manually and regularly, which is inconvenient and poses a risk of omission, affecting the overall ease of use;

[0050] 2. Serious residue problems, which endanger equipment life: The agent is easy to adhere to the inner wall of the flushing section or other flow channel components. Long-term use may lead to pipe blockage, material aging, or even corrosion of the equipment structure, shortening the product's service life.

[0051] 3. Insufficient safety and potential health risks: Some chemical components are irritating to human skin and mucous membranes, and may cause discomfort, especially to children, the elderly or people with sensitive constitutions;

[0052] 4. Complex structure and high manufacturing and maintenance costs: Chemical cleaning requires the design of an independent dosing water circuit and mixing device, which increases the complexity of the system structure and manufacturing costs, and also places higher demands on subsequent maintenance.

[0053] Therefore, smart toilet seats urgently need to be equipped with a highly efficient, long-lasting, and automated disinfection and sterilization function to effectively inhibit the growth of microorganisms and ensure the hygiene and safety of the cleaning process and the stability of equipment operation.

[0054] Against this backdrop, water electrolysis-based sterilization technology is considered a promising solution due to its unique advantages. This technology generates anode products with strong oxidizing capabilities through electrolysis, which can disrupt microbial cell walls and protein structures, achieving broad-spectrum and highly efficient sterilization.

[0055] More importantly, the final product of electrolytic sterilization technology is mainly water, which does not produce harmful residues. It has significant advantages such as no chemical pollution, environmental safety, and no harm to the human body. It is very much in line with the high standards of cleaning and hygiene required by smart toilet seats and also conforms to the current development trend of green home appliances.

[0056] However, despite the sound theoretical foundation and application potential of electrolytic sterilization technology, its promotion in actual products still faces the following key technical bottlenecks that urgently need to be overcome:

[0057] 1. The problem of reduced sterilization efficacy in mixed-flow output mode:

[0058] In the mode of mixed output of cathode and anode products, the hydrogen generated on the cathode side will continuously consume the anode bactericidal substances, resulting in a decrease in the overall oxidation-reduction potential of the electrolyzed water, which makes it difficult to meet the actual needs of rapid sterilization and efficient disinfection in toilet cleaning.

[0059] 2. Resource waste in split output mode:

[0060] Although separating the anode and cathode products can preserve the strong bactericidal ability of the anode products, the cathode products are usually regarded as "wastewater" and discharged directly, resulting in water waste, increased water consumption and sewage discharge of the whole machine, and increased maintenance burden on users.

[0061] 3. Limitations of relying on electrolyzed brine:

[0062] While adding brine to electrolysis can enhance the sterilization stability and efficiency of the anode products to some extent, this method requires users to regularly replenish the electrolysis chamber with chloride-containing electrolyte, which is cumbersome and affects ease of use and user experience. Furthermore, long-term use of chlorinated electrolyzed water may corrode the internal structure of the equipment, affecting product reliability and lifespan.

[0063] To address the aforementioned technical challenges, this utility model provides a smart toilet seat that utilizes water electrolysis for sterilization. While fully inheriting the advantages of electrolytic sterilization technology, such as environmental friendliness, high efficiency, and residue-free operation, it innovatively solves the problems of insufficient sterilization efficacy, resource waste, and environmental pollution inherent in existing electrolysis methods. It achieves efficient, environmentally friendly, and sustainable automatic sterilization, fully meeting the growing demands of modern families for hygienic, intelligent, and energy-efficient smart cleaning devices. The technical solution of this utility model will be described in detail below:

[0064] Please see Figures 1 to 10 According to an embodiment of this utility model, a smart toilet seat that uses electrolyzed water for sterilization is provided, comprising: a first water supply path 1 and a flushing part 2 telescopically disposed on the toilet seat body 6, wherein the first water supply path 1 is connected to the flushing part 2; an electrolysis module 4 disposed on the first water supply path 1; the electrolysis space of the electrolysis module 4 is divided by a first separator 405 into a cathode chamber 404 disposed with a cathode 403 and an anode chamber 402 disposed with an anode 401, wherein the inlet 411 and outlet 412 of the electrolysis space are both disposed in the anode chamber 402, and the first separator 405 is an ion channel for cations.

[0065] As can be seen, this utility model, by setting an electrolysis module 4 on the first water supply path 1, transforms the water entering the electrolysis module 4 into electrolyzed water with highly efficient sterilization and disinfection capabilities under the action of electrochemical reactions. This electrolyzed water is rich in highly active oxidizing substances (such as active oxygen), and has broad-spectrum, rapid, and residue-free sterilization characteristics.

[0066] This electrolyzed water can not only perform regular or automated sterilization and cleaning of the first water supply path 1 and its related components, effectively inhibiting the growth of mold, bacteria, and other microorganisms caused by long-term exposure to a humid environment, but also avoids the problems of secondary pollution and odor caused by internal water contamination in traditional smart toilet seats, thus significantly improving the overall hygiene and safety level of the device. Simultaneously, during use, the electrolyzed water can also be used for rinsing the buttocks, replacing traditional plain water rinsing. This application can effectively remove bacteria and organic pollutants attached to the skin surface, making it particularly suitable for people with low immunity or users with high requirements for personal hygiene.

[0067] Compared with the disinfectants used in traditional smart toilet seats, the electrolyzed water-based sterilization solution provided by this invention has the following significant advantages: Electrolyzed water is generated quickly, resulting in rapid sterilization without prolonged irradiation or waiting, effectively sterilizing the target area in a short time; the active ingredients in the electrolyzed water can effectively kill various common pathogenic microorganisms, including Escherichia coli, Staphylococcus aureus, and Candida albicans, with a high sterilization rate and strong applicability; moreover, the active ingredients in the electrolyzed water not only kill bacteria but also effectively inhibit bacterial growth and eliminate odor sources such as organic residues. This technology reduces odor generation; electrolyzed water is non-toxic and residue-free, posing no potential health risks or corrosion to the internal structure of the equipment, making it safer and more environmentally friendly; it requires only ordinary tap water as a raw material, eliminating the need for additional chemical agents and avoiding chemical waste and environmental pollution; furthermore, the electrolysis module 4 can be flexibly integrated into the existing water system of a smart toilet seat, eliminating the need for complex dosing devices or mixing structures, simplifying the system construction, improving the overall reliability and manufacturing economy of the product, and facilitating its widespread application in various smart bathroom products. Therefore, by introducing electrolyzed water sterilization technology, not only are the shortcomings of traditional smart toilet seats in sterilization function addressed, but cleaning, odor removal, and sterilization are achieved simultaneously, improving overall hygiene and safety.

[0068] Meanwhile, by setting a first separator 405 with cation channel function in the electrolysis space of the electrolysis module 4, transmembrane transport of cations such as hydrogen ions is realized. The first separator 405 divides the electrolysis space into an anode chamber 402 with an anode 401 and a cathode chamber 404 with a cathode 403. The inlet 411 and outlet 412 of the electrolysis module 4 are both located in the anode chamber 402. Therefore, when the raw water enters the electrolysis space from the inlet 411, it first participates in the electrolysis reaction at the anode 401, and the generated cations such as hydrogen ions enter the cathode chamber 404 through the cation channel of the first separator 405, and continue to participate in the electrolysis reaction at the cathode 403.

[0069] This unique structural design allows the anolyte products generated during electrolysis to fully participate in the cleaning process, leveraging their high oxidation-reduction potential to more efficiently kill bacteria, viruses, and other harmful microorganisms in the first water supply path 1 and the flushing section 2. Compared to traditional cleaning methods and existing mixed-flow output electrolysis technology, this design significantly enhances the sterilization and disinfection effect, better meeting the needs of scenarios with high hygiene requirements and effectively reducing the risk of cross-contamination.

[0070] Furthermore, this structural design avoids the water waste caused by the direct discharge of cathode products in the split-output mode, and solves the problems of cumbersome operation and increased operating costs associated with traditional methods that rely on adding detergents or disinfectants. At the same time, it avoids the potential health risks from the pungent odors and harmful gases released by detergents or disinfectants, as well as the secondary pollution to the environment, further enhancing the user experience and equipment safety.

[0071] In summary, the smart toilet seat using electrolyzed water sterilization provided by this utility model not only effectively solves the technical problems of insufficient sterilization efficiency, resource waste, and environmental pollution in existing electrolyzed sterilization toilet seats, but also achieves efficient odor removal function, significantly improving the overall hygiene level and user comfort, and has good application prospects and promotion value.

[0072] Furthermore, such as Figure 1 and Figure 2 As shown, the smart toilet seat that uses electrolyzed water for sterilization also includes: a toilet seat body 6 and an openable lid 7, the lid 7 being used to completely seal or avoid the toilet seat body 6 and its internal space. A retractable flushing section 2 is provided on the toilet seat body 6.

[0073] Furthermore, such as Figure 3 As shown, the smart toilet seat that utilizes electrolyzed water for sterilization also includes a heating component 3. The heating component 3 is disposed on the first water supply path 1 and in front of the water inlet 411 of the electrolysis module 4. This heating component 3 heats the water flowing into the electrolysis module 4, ensuring it reaches a suitable temperature for human washing before being delivered to the electrolysis module 4 for electrolysis, thereby achieving a temperature-controlled washing function. Compared to a structure that electrolyzes first and then heats, the above-described structure ensures that the electrolyzed water output to the washing section 2 not only has a comfortable washing temperature but also maintains highly efficient sterilization capabilities, significantly improving the user experience.

[0074] Furthermore, the rinsing section 2 has multiple spray holes or multiple spray sections, which are spaced apart on the body of the rinsing section 2 to accommodate the needs of different modes.

[0075] Specifically, multiple spray holes or multiple spray sections are evenly distributed on the surface of the rinsing section 2, forming diverse water jet paths. This layout allows for adjustments to the direction, intensity, and coverage of the water flow according to different needs (such as posterior washing, feminine wash, self-cleaning, etc.), ensuring optimal results with each rinse.

[0076] It should be noted that in practical applications, one or more combinations of spray holes or spray sections can be flexibly selected based on specific design requirements, water pressure, coverage area, and cleaning effect to achieve the best spraying effect in different usage scenarios.

[0077] Furthermore, such as Figure 3 As shown, the smart toilet seat that utilizes electrolyzed water for sterilization also includes a control valve 5. The control valve 5 is located on the first water supply path 1, at the end of the electrolysis module 4 furthest from the flushing section 2. This structural arrangement, with the control valve 5 installed on the first water supply path 1, allows for precise control of the water flow during the operation of the flushing section 2. Specifically, the control valve 5 only opens when the flushing section 2 needs to be activated for a flushing operation, allowing water to flow through the first water supply path 1 to the electrolysis module 4 for processing; when no flushing operation is required, the control valve 5 remains closed, thus interrupting the water flow and avoiding unnecessary water consumption and ineffective operation of the electrolysis module 4.

[0078] Furthermore, the smart toilet seat that uses electrolyzed water for sterilization also includes a controller, which is communicatively connected to the control valve 5 and the heating component 3, respectively, and is used to control the operation of the control valve 5 and the heating component 3.

[0079] Alternatively, the working process of a smart toilet seat that uses electrolyzed water for sterilization is as follows:

[0080] 1. Perform self-cleaning on the rinsing section.

[0081] When the system detects that the rinsing section 2 needs cleaning and maintenance (such as scheduled periodic cleaning or automatic cleaning after use), the controller opens the control valve 5 and ensures that the heating component 3 is in the off state. At this time, water flows through the control valve 5 into the electrolysis module 4, where it is converted into electrolyzed water with highly efficient sterilization capabilities under the action of electrochemical reaction. This electrolyzed water is then delivered to the rinsing section 2. The electrolyzed water flows out from the corresponding spray holes or nozzles on the rinsing section 2, thoroughly rinsing and disinfecting its internal channels and external surfaces, effectively removing residual dirt and microorganisms, and preventing bacterial growth.

[0082] 2. Activate different modes of body washing function

[0083] When a user triggers the rinsing function for personal hygiene, the controller simultaneously activates control valve 5 and heating component 3 according to a preset mode or user-selected command. These components maintain a constant temperature based on the user-set temperature or ambient temperature, ensuring the output water is at a comfortable temperature for human contact. Water flows through control valve 5 and heating component 3 into electrolysis module 4, generating electrolyzed water with sterilization function. Subsequently, the electrolyzed water is delivered to rinsing section 2 and sprayed out through corresponding nozzles or spray holes, providing a gentle rinse to the buttocks or intimate areas. Depending on the rinsing mode (such as normal washing, feminine hygiene, pulse massage, etc.), the system can flexibly control the actions of different spray sections, providing a personalized and comfortable rinsing experience.

[0084] This workflow not only achieves efficient cleaning for users, but also further enhances the safety and hygiene standards of the rinsing process by leveraging the broad-spectrum bactericidal properties of electrolyzed water.

[0085] It should be noted that:

[0086] Status management of the flushing unit 2: When cleaning the flushing unit 2 or washing a person, the flushing unit 2 should be in the extended state, extending into the toilet bowl to ensure that it can fully contact the area to be cleaned. When the flushing unit 2 is not in use (such as when it is not being cleaned or washed), the flushing unit 2 will automatically retract into the toilet seat to maintain the overall appearance of the device and prevent dust accumulation.

[0087] Application scenarios of heating component 3: Heating component 3 is mainly used to provide warm water for human body cleaning. When performing system cleaning operations, heating function is usually not required. Therefore, heating component 3 will be set to stop heating state to save energy and avoid unnecessary heat loss.

[0088] Specifically, such as Figure 3 As shown, the smart toilet seat that uses electrolyzed water for sterilization also includes a water pump 8, which is installed on the first water supply path 1. The water pump 8 is used to provide power support for the water flow to ensure that the electrolyzed water can be stably and efficiently delivered to the flushing section 2.

[0089] It should be noted that the location of the water pump in the first water supply path 1 can be flexibly adjusted according to the actual product structure design and spatial layout requirements.

[0090] Preferably, the water pump 8 is located between the heating assembly 3 and the flushing section 2.

[0091] To optimize the structure of the electrolysis module 4 and improve the redox potential of the anode product, in the first embodiment of the electrolysis module 4 provided by this utility model, such as... Figures 7 to 10As shown, in this embodiment, the electrolysis space of the electrolysis module 4 includes a cathode chamber 404 with a cathode 403 and an anode chamber 402 with an anode 401. The cathode chamber 404 and the anode chamber 402 are separated by a first partition 405, which is provided with a water-blocking structure. The water inlet 411 and the water outlet 412 of the electrolysis space are both located on one side of the anode chamber 402, and the first partition 405 serves as an ion channel for cations.

[0092] The electrolysis process of electrolysis module 4 is as follows: During electrolysis, water flows into the anode chamber 402 through the inlet 411, where an electrolysis reaction occurs at the anode 401. The generated hydrogen ions and other cations then pass through the first separator 405 into the cathode chamber 404, where they continue to participate in the electrolysis reaction at the cathode 403, generating cathode products such as hydrogen gas. The specific electrolysis reaction formula is as follows:

[0093] At anode 401: 4H2O-4e - →O2↑+2H2O+4H + ;

[0094] Cathode 403: 2H + +2e - →H2↑;

[0095] Since no additional water inlet 411 is provided at the cathode chamber 404, and the cathode chamber 404 and the anode chamber 402 are separated by the first partition 405, the water volume in the cathode chamber 404 is limited during the electrolysis process. Therefore, in order to avoid the cathode 403 from dry burning during the electrolysis process, a first gap 407 is provided between the first partition 405 and the peripheral wall of the electrolysis space. The cathode chamber 404 and the anode chamber 402 are connected through the first gap 407, so that the water flow in the anode chamber 402 can enter the cathode chamber 404 through the first gap 407. This part of the water flow can prevent the cathode 403 from dry burning.

[0096] Through the above structural design, the inventors unexpectedly discovered that although connecting the cathode chamber 404 and the anode chamber 402 through the first gap 407 would cause some cathode products to diffuse into the anode chamber 402, thereby causing some consumption of anode products, compared with the traditional mixed flow structure, the electrolysis module 4 of this utility model can still significantly improve the oxidation-reduction potential of the actual output electrolysis products, thereby ensuring that the water flow or water mist output by the rinsing section 2 has sufficient sterilization and cleaning capabilities. It can not only efficiently complete the disinfection treatment of the internal flow channel and external surface of the rinsing section itself, but also effectively achieve the cleaning of the human body, comprehensively improving the hygiene and safety and user comfort of the rinsing process.

[0097] Through experiments, the inventors have found that although the electrolysis module 4 of this invention does not have an additional water inlet 411 in the cathode chamber 404, and the cathode chamber 404 and anode chamber 402 are separated by the first separator 405, limiting the amount of water in the cathode chamber 404 during electrolysis, due to the limited water volume, only a small portion of the hydrogen generated at the cathode 403 dissolves in the water and diffuses into the anode chamber 402 through the first gap 407 with the water flow, causing unnecessary consumption of the anode product; the majority of the remaining hydrogen diffuses into the anode chamber 402 in a gaseous state through the first gap 407. Compared with hydrogen dissolved in water, the probability of gaseous hydrogen reacting with the liquid anode product is smaller. Therefore, most of this hydrogen is directly discharged through the water outlet 412, thus resulting in a significant increase in the redox potential of the output electrolysis product even when the present invention outputs the electrolysis product in a similar mixed-flow manner. In contrast, under the traditional mixed-flow structure, since the amount of water in the cathode chamber 404 is relatively large or can be replenished in time, most of the hydrogen generated at the cathode 403 dissolves in the water. The hydrogen dissolved in the water has a high probability of coming into contact with the anode products, thus causing more consumption of the anode products and resulting in a greater limitation on the redox potential of the output electrolytic products.

[0098] On the other hand, after the gaseous hydrogen is discharged through the outlet 412 of the electrolysis module 4, it can diffuse into the external environment on its own without any additional treatment. Therefore, this invention greatly improves the redox potential of the output electrolysis product without adding any steps to the process, achieving unexpected technical results.

[0099] Furthermore, it should be noted that the first partition 405 with a water-blocking structure in this utility model can limit most of the water flow in the anode chamber 402 from diffusing into the cathode chamber 404. However, since the hydrogen ions and other cations generated at the anode 401 need to pass through the first partition 405 to enter the cathode chamber 404 and continue to participate in electrolysis, and water is required as a medium during the migration of ions, the first partition 405 can allow ions to carry some water through during the migration process. This water can also prevent the cathode 403 from burning dry during the electrolysis process.

[0100] Furthermore, since the first separator 405 has a water-blocking function while allowing cations to pass through, if its structure allows hydrogen to diffuse across the membrane in gaseous form, it may bring new problems. Specifically, the hydrogen generated during electrolysis exists in the form of hydrogen anions. These ions have high chemical activity due to carrying extra electrons, and can easily pass through the first separator 405 into the anode chamber 402, where they undergo side reactions with the anode products, resulting in the ineffective consumption of the anode bactericidal components, thereby reducing the bactericidal efficiency of the electrolyzed water.

[0101] To address the aforementioned issues, this embodiment preferably incorporates a gas check structure on the first separator 405 to restrict hydrogen from directly passing through and diffusing into the anode chamber 402. This reduces the consumption of anode products by cathode products, ensuring the required amount of electrolytic products output from the electrolysis module outlet. Consequently, it ensures that the water flow or mist output from the rinsing section 2 has sufficient sterilization and cleaning capabilities. This not only efficiently disinfects the internal flow channels and external surfaces of the rinsing section itself but also effectively cleans the human body, comprehensively enhancing the hygiene, safety, and comfort of the rinsing process.

[0102] Through this structural design, the hydrogen gas generated during electrolysis can only diffuse directionally through the first gap 407 between the cathode 403 and the first separator 405, rather than permeating randomly. During this process, hydrogen anions lose excess electrons and transform into inactive hydrogen molecules. Even if this type of hydrogen gas enters the anode chamber 402, it is less likely to react with the anode products, thereby further reducing unnecessary losses of anode products and increasing the redox potential of the output electrolysis products.

[0103] Experimental data show that, under the premise that other electrolysis conditions are the same, the redox potential of the electrolysis product output by this invention can be increased from about 700mV in the traditional mixed flow mode to more than 820mV, which significantly enhances the bactericidal ability of electrolyzed water.

[0104] As an optional solution, the first separator 405 can be implemented using a cation exchange membrane, a polytetrafluoroethylene (PTFE) composite membrane, a multilayer hydrophobic coating membrane, or other structural materials. Wherein:

[0105] Polytetrafluoroethylene composite membranes effectively block the penetration of various gases, including hydrogen, by dispersing perfluorosulfonic acid membranes within a porous PTFE framework and utilizing its excellent hydrophobicity and density.

[0106] Multilayer hydrophobic coating membranes are made by coating an ultrathin polyvinylidene fluoride (PVDF) coating on the surface of the cation exchange layer, forming a dual barrier against liquid water and gas.

[0107] Considering that cations such as hydrogen ions need to enter the cathode chamber 404 through the first separator 405 and continue to participate in the electrolysis reaction at the cathode 403, the closer the cathode 403 is to the first separator 405, the lower the voltage required to drive ion migration. Therefore, it is preferable to place the cathode 403 in close contact with the first separator 405.

[0108] When the cathode 403 is installed in close contact with the first separator 405, in order to ensure the smooth discharge of hydrogen, a second gap 408 needs to be provided between the cathode 403 and the peripheral wall of the cathode chamber 404, and the second gap 408 is connected to the first gap 407, so that the hydrogen generated at the cathode 403 can enter the anode chamber 402 through the second gap 408 and the first gap 407, and finally be discharged through the outlet 412.

[0109] Alternatively, while the cathode 403 and the first separator 405 are in close contact, the cathode 403 and the first separator 405 can be adjusted to be in a gap configuration, that is, a second gap 408 is still left between the cathode 403 and the first separator 405. In this case, the hydrogen gas generated at the cathode 403 can enter the anode chamber 402 through the second gap 408 and the first gap 407 between the cathode 403 and the first separator 405.

[0110] It should be noted that in this embodiment, there is a difference between gap setting and interval setting. Gap setting leaves a gap between the two while keeping them in close contact, and the size of the gap is small. Interval setting, on the other hand, makes the distance between the two more obvious.

[0111] Due to the limited size of the second gap 408, the diffusion rate of hydrogen from the cathode chamber 404 to the anode chamber 402 is relatively slow, causing it to accumulate in the cathode chamber 404 and continuously expand in volume. This expansion exerts an impact force on the first separator 405, and may even cause it to bulge out towards the anode chamber 402. Therefore, it is preferable to provide the second gap 408 between the cathode 403 and the peripheral wall of the cathode chamber 404, and between the cathode 403 and the first separator 405, to improve the hydrogen diffusion efficiency and reduce the impact on the first separator 405.

[0112] Further considering the utilization rate of cathode 403: Since hydrogen ions enter the cathode chamber 404 through the first separator 405, if the area of ​​cathode 403 is equal to the area of ​​the first separator 405, then hydrogen ions can only participate in the electrolysis reaction on the side of cathode 403 facing the first separator 405. Consequently, the other side of cathode 403 is not fully utilized, resulting in a low utilization rate of cathode 403. Alternatively, if a second gap 408 is provided between cathode 403 and the peripheral wall of cathode chamber 404, although the cathode chambers 404 on both sides of cathode 403 can be connected through the second gap 408, allowing water flow to participate in electrolysis at the cathode 403 on the side away from the first separator 405, the diffusion rate of hydrogen to the cathode chamber 404 on the other side of cathode 403 is slow due to the size limitation of the second gap 408. Most of the hydrogen generated during electrolysis still accumulates between the first separator 405 and cathode 403, causing a significant impact on the first separator 405.

[0113] Therefore, in this embodiment, it is preferable that the area of ​​the cathode 403 is smaller than the area of ​​the first separator 405. For example, multiple cathodes 403 can be arranged at intervals, or at least one first diffusion hole can be provided through the cathode 403. In this way, hydrogen ions entering the cathode chamber 404 through the first separator 405 can enter the cathode chamber 404 on the other side of the cathode 403 through the gap between adjacent cathodes 403 or the first diffusion hole, and participate in electrolysis at the cathode 403 on the side away from the first separator 405, thus utilizing the cathode 403 at this location.

[0114] Meanwhile, the cathode chamber 404 here can also be used to contain hydrogen gas that has not yet diffused into the anode chamber 402, so as to reduce the impact of hydrogen gas on the first separator 405 and extend the service life of the first separator 405. Moreover, compared with the design of multiple independent cathodes 403, the method of setting the first diffusion hole on a single cathode 403 is more conducive to maintaining the integrity and stability of the cathode 403, and is also easier to assemble.

[0115] To further limit the position of the cathode 403 and maintain a gap between it and the first separator 405, a conductive element 413 is also provided in the cathode chamber 404 in this embodiment. The conductive element 413 has a hollow frame structure to allow space for hydrogen gas. One side of the conductive element 413 is attached to the cathode 403, and the opposite side is attached to the inner wall of the cathode chamber 404 to support the cathode 403. For easy connection, the conductive element 413 extends outward through the peripheral wall of the cathode chamber 404, with a conductive end.

[0116] In the above embodiment, the hydrogen generated at the cathode 403 can be output to the anode chamber 402 due to the second gap 408. However, due to the size limitations of the second gap 408 and the first gap 407, the output efficiency of the hydrogen is slow. Therefore, the hydrogen in the cathode chamber 404 will cause greater pressure on the first partition 405.

[0117] Therefore, the structure of the anode 401 has been optimized in this embodiment. Specifically, the anode 401 needs to be closely attached to the first partition 405 so that the anode 401 can limit the first partition 405 from another direction. At this time, a third gap 409 needs to be provided between the anode 401 and the peripheral wall of the anode chamber 402, and the third gap 409 is connected to the first gap 407 so that the hydrogen in the cathode chamber 404 can diffuse into the anode chamber 402 and finally be discharged through the outlet 412.

[0118] And / or, in this embodiment, the anode 401 and the first separator 405 can be adjusted to be spaced apart while being tightly attached. A third gap 409 can be provided between them, and the third gap 409 is connected to the first gap 407. At this time, the anode 401 can still limit the first separator 405 from another direction, thereby offsetting the pressure of hydrogen on the first separator 405.

[0119] If the area of ​​the anode 401 is equal to the area of ​​the first separator 405, considering that the anode 401 needs to limit the first separator 405, the two are set close together or a third gap 409 is left. The water flow in the anode chamber 402 on the side away from the first separator 405 participates in electrolysis at the anode 401 to generate hydrogen ions. However, the generated hydrogen ions cannot pass through the first separator 405 due to the obstruction of the anode 401 and continue to participate in electrolysis at the cathode 403. They can only go around from the first gap 407 to the cathode 403 to continue to participate in electrolysis. As the ion migration path increases, the voltage required for electrolysis increases accordingly.

[0120] Therefore, in this embodiment, the area of ​​the anode 401 is preferably smaller than the area of ​​the first separator 405, so that the hydrogen ions generated at the anode 401 can pass through the first separator 405 and continue to participate in electrolysis at the cathode 403 along a shorter path.

[0121] For example, multiple anodes 401 can be provided, with adjacent anodes 401 spaced apart, or at least one second diffusion hole can be provided through anode 401. Compared with multiple spaced anodes 401, providing a second diffusion hole on anode 401 allows anode 401 to remain a single unit, resulting in better stability and easier installation.

[0122] Furthermore, to limit the position of the anode 401, the electrolysis module 4 in this embodiment has a conductive element 413 with a frame structure on the side of the anode 401 away from the first separator 405. The conductive element 413 is hollow to accommodate the water flow participating in electrolysis. One side of the conductive element 413 abuts against the anode 401, and the opposite side abuts against the inner wall of the anode chamber 402 to support the anode 401. To facilitate electrical connection, the conductive element 413 extends outward through the peripheral wall of the anode chamber 402, with a conductive end.

[0123] To further optimize the structural design of the electrolysis module 4, an improved scheme is proposed in the second embodiment of the electrolysis module 4 provided by this utility model: by setting a hydrogen outlet 406 in the cathode chamber 404, active control of the hydrogen emission path is achieved. Although the possibility of hydrogen entering the anode chamber 402 and reacting with the anode products has been reduced by the first gap 407 in the aforementioned embodiment, some hydrogen dissolved in water still diffuses into the anode chamber 402 through this gap, resulting in the ineffective consumption of the anode bactericidal components.

[0124] Therefore, in this embodiment, as Figure 4 and Figure 5 As shown, in this embodiment, instead of the first gap 407 for dispersing hydrogen, a hydrogen outlet 406 is provided at the cathode chamber 404. The hydrogen outlet 406 connects the cathode chamber 404 to the outside of the anode chamber 402, so that hydrogen can be discharged directly through the outlet, thereby further reducing its interference and consumption on the anode products.

[0125] To ensure that hydrogen can be smoothly discharged through hydrogen outlet 406 and to prevent it from diffusing across the membrane in gaseous form into anode chamber 402, the first separator 405 is functionally enhanced in this embodiment to enable it to block hydrogen. Specifically, the first separator 405 is preferably configured with a gas check structure, which can effectively prevent hydrogen from passing through while allowing cation migration.

[0126] Optionally, the first separator 405 can be configured as an ultrafiltration membrane, a hydrophilic cation exchange membrane, a negatively charged nanofiltration membrane, or a mixed matrix membrane, etc., allowing water flow while permitting cation passage, and simultaneously blocking the transmembrane diffusion of hydrogen gas generated at the cathode 403.

[0127] Hydrophilic cation membranes adsorb water molecules through hydrophilic groups such as sulfonic acid groups to form a hydration layer, providing a transport channel for cations and water. Non-polar gas molecules are blocked because they cannot form hydrogen bonds or electrostatic interactions with the hydration layer, thus achieving the function of gas anti-reverse flow.

[0128] Negatively charged nanofiltration membranes have a negatively charged surface. Their pore size can block gases, while cations and water can pass through. By incorporating hydrophilic groups, a dynamic hydration layer can be formed, enhancing water transport. Gases are trapped due to their hydrophobicity, nonpolarity, and low solubility, thus achieving a gas anti-reverse function.

[0129] The hybrid matrix membrane uses organic polymers as the matrix and inorganic nanomaterials such as zeolite and metal-organic frameworks (MOFs) are uniformly dispersed inside. The surface charge and hydrophilicity of the materials can promote the transport of cations and water, and the gas anti-reverse function can be achieved by controlling the pore size distribution.

[0130] Furthermore, in order to prevent the reducing substances in the cathode chamber 404 from diffusing into the anode chamber 402 with the water flow and affecting the stability of the anode products, a water-blocking structure is preferably added to the first partition 405 in this embodiment.

[0131] It should be noted that although the first separator 405 in this utility model can limit most of the water flow in the anode chamber 402 to diffuse into the cathode chamber 404, since the hydrogen ions and other cations generated at the anode 401 need to pass through the first separator 405 to enter the cathode chamber 404 to continue participating in electrolysis, and water is required as a medium during the migration of ions, the first separator 405 can allow ions to carry some water through during the migration process. This water can also prevent the cathode 403 from burning dry during the electrolysis process.

[0132] Therefore, the first separator 405 can be configured as a cation exchange membrane, a hydrophobic MOF (metal-organic framework) membrane, a hydrophobic COF (covalent organic framework) membrane, or a hydrophobic mixed matrix membrane, etc.

[0133] This structural design allows hydrogen ions to carry some water into the cathode chamber 404, preventing the cathode 403 from burning dry, while also preventing the cathode products from consuming the anode products. The cation exchange membrane is preferably a proton exchange membrane.

[0134] Hydrophobic MOF and COF membranes form low surface energy interfaces by introducing hydrophobic functional groups such as fluorinated groups, which block the permeation of polar water molecules and gases; their pore surfaces are modified with negatively charged groups to promote cation migration.

[0135] The hydrophobic hybrid matrix membrane uses hydrophobic polymers such as polyvinylidene fluoride as the matrix and embeds hydrophilic inorganic nanoparticles such as zeolite and sulfonated carbon nanotubes. It forms a continuous ion transport channel through hydrophilic fillers, allowing cations and their hydrated ions to pass through, while preventing gas diffusion across the membrane through the hydrophobic matrix.

[0136] Experimental data show that, under the premise that other electrolysis conditions are the same, the oxidation-reduction potential (ORP) of the electrolysis product output in this embodiment can be increased from 820mV in the previous embodiment to more than 1000mV, which significantly enhances the bactericidal ability of electrolyzed water.

[0137] In addition, as hydrogen ions carry water into the cathode chamber 404, to prevent water from being discharged simultaneously from the hydrogen outlet 406 during the exhaust process, a gas-liquid separation unit, such as a hydrophobic and breathable material like a polytetrafluoroethylene (PTFE) membrane, is also provided at the hydrogen outlet 406 in this embodiment. This structure only allows hydrogen to pass through, while retaining the water flow within the cathode chamber 404.

[0138] Even after the chamber is full of water, the electrolysis reaction can continue. When hydrogen ions carry water in, the water in the original chamber flows back to the anode 401 region to continue participating in the electrolysis process. Therefore, in this embodiment, most of the incoming water can be electrolyzed at the anode 401, significantly improving water resource utilization efficiency.

[0139] In contrast, existing technologies typically rely on cation exchange membranes to isolate the cathode chamber 404 and the anode chamber 402 to prevent cathode products from diffusing to the anode side and causing losses, i.e., collecting cathode and anode products separately. However, due to the selective permeability limitations of ion exchange membranes, even if water in the cathode chamber participates in electrolysis, the generated hydroxide ions cannot return to the anode chamber 402. This means that this water is only used to dissolve cathode products and protect the electrode from dry burning, and does not actually participate in the electrolysis reaction at the anode, thus reducing the overall electrolysis efficiency and the yield ratio of water electrolysis products. In summary, this embodiment overcomes the technical biases of the prior art, and while avoiding the consumption of anode products by cathode products, allows most of the raw water for electrolysis to participate in electrolysis at the anode 401, significantly improving the conversion ratio of electrolysis products to influent water, and ensuring the utilization rate of water resources.

[0140] To further improve the utilization efficiency of the electrodes during electrolysis, in the third embodiment of the electrolysis module 4 provided by this utility model, a water-blocking component 410 is introduced to optimize the water flow path, thereby achieving full coverage of the electrode surface and efficient electrolysis. Specifically:

[0141] In existing technologies, electrodes are typically sheet-like structures for ease of processing. With such structures, a straight path often forms between the inlet 411 and the outlet 412. This means that water entering the electrolysis space through the inlet 411 tends to flow directly out through the outlet 412 along the shortest path. For electrodes located far from the inlet 411 and outlet 412, the water flow often fails to reach them. This results in these electrodes not fully participating in electrolysis, thus wasting electrode area. Furthermore, because the water flows out through the outlet 412 along the shortest path, the electrolysis time is correspondingly short, and the actual output electrolysis products often fail to meet expected performance indicators.

[0142] Therefore, as Figure 6 As shown, to prevent the electrodes at the corners from failing to fully participate in electrolysis, at least one water-blocking element 410 is provided in the anode chamber 402 in this embodiment. The water-blocking element 410 divides the initial water path between the inlet 411 and the outlet 412 into several interconnected second flow paths 414. Since the width of the second flow path 414 is smaller than the width of the initial water path, the water flow is guided through the second flow path 414, allowing the water flow to cover a larger area of ​​the anode 401, thus significantly improving the utilization rate of the anode 401.

[0143] Optionally, if only one water-blocking element 410 is provided, it is preferable to evenly distribute the second flow paths 414 on both sides. In this case, the width ratio of the second flow path 414 to the initial water path is 0.5. Therefore, in this embodiment, it is preferable to set the ratio to ≤0.5 to ensure that the water flow fully covers the electrode surface.

[0144] Optionally, if several water-blocking components 410 are provided, adjacent second flow paths 414 are connected by a transition section, which is U-shaped. In this case, the connected second flow paths 414 extend the flow path of the electrolyzed raw water. Under the guidance of the second flow paths 414, the water flow can fully cover all areas of the anode 401, thereby improving the utilization rate of the anode 401.

[0145] In addition to limiting the width of the second flow path 414, in this embodiment, the length ratio of any water-blocking component 410 to the length of the anode 401 is greater than or equal to 0.5, so as to ensure the extension length of the second flow path 414, so that it can cover more area of ​​the anode 401, and avoid the second flow path 414 being too short, resulting in the transition section being too wide, which would prevent the water flow from fully covering the anode 401 when it flows through the transition section.

[0146] On the other hand, in order to further increase the area of ​​the anode 401 covered by the water flow, in this embodiment the water inlet 411 of the electrolysis module 4 is located at the end of the second flow path 414 away from the transition section, so that the electrolyzed raw water can cover the area of ​​the anode 401 from the water inlet 411 to the transition section.

[0147] And / or, in this embodiment, the outlet 412 of the electrolysis module 4 is located at the end of the second flow path 414 away from the transition section, so that the water flow can cover the area of ​​the anode 401 from the outlet 412 to the transition section.

[0148] Alternatively, to increase the utilization rate of the electrode, the anode 401 can be configured as at least part of the peripheral wall of the anode chamber 402, that is, one side of the anode 401 is the anode chamber 402, and the other side is the first partition 405; and the anode 401 can be configured to form a semi-closed or closed enclosure for the electrolyzed raw water in the anode chamber 402. The cathode chamber 404 is correspondingly fitted outside the anode chamber 402.

[0149] When the anode 401 forms a closed enclosure around the electrolyzed raw water in the anode chamber 402, the anode 401 becomes tubular, and its internal hollow area is the anode chamber 402. This structural form fully guarantees the electrolysis area when the volume of the electrolysis module 4 is limited.

[0150] At the normal inlet flow rate for daily water use, the raw water for electrolysis enters the anode chamber 402 in a turbulent manner. Under the influence of the turbulent and irregular flow field, the raw water for electrolysis continuously impacts the anode 401 surrounding it and participates in electrolysis. Therefore, under this structural configuration, the utilization rate of the anode 401 and the electrolysis efficiency can still be guaranteed.

[0151] Furthermore, to prevent the electrodes from burning out due to the electrolysis module 4 operating in a waterless state, this embodiment also includes a humidity-sensitive element for automatically controlling the operating state of the electrolysis module 4, i.e., controlling the start and stop of the electrolysis module 4. Specifically:

[0152] When water passes through the electrolysis module 4, as the humidity increases, the humidity-sensitive element automatically controls the control circuit of the electrolysis module 4 to conduct electrolysis on the water flowing through it; when water does not pass through the electrolysis module 4, as the humidity decreases, the humidity-sensitive element automatically controls the control circuit of the electrolysis module 4 to turn off to prevent the electrodes inside from drying out.

[0153] By incorporating a humidity-sensitive element, the starting efficiency of the electrolysis module 4 can be fully guaranteed while avoiding dry burning. This ensures that the internal flow channels and external surfaces of the rinsing unit can be effectively disinfected, while also effectively cleaning the human body, thus comprehensively improving the hygiene, safety, and comfort of the rinsing process.

[0154] After conducting experiments to verify the above structural design, the inventors found that the electrolysis module 4 provided in this application has significant technical advantages and practical value compared with traditional toilet seats that use ultraviolet sterilization, high-temperature sterilization, detergents or bactericides: This utility model uses water as raw material and generates electrolyzed water with strong oxidizing ability through electrolysis. It does not require the addition of any chemical bactericides, avoids the irritating odor and harmful gas release problems that may be caused by traditional bactericides, and has no adverse effects on human health.

[0155] The inventors also discovered that, with the electrolysis module 4 described in this application, the water flow or mist output from the rinsing section 2 can not only clean and disinfect the rinsing section 2 itself and clean the human body, but also emulsify the oil stains adhering to the rinsing section 2. That is, using the electrolysis module 4 of this invention saves time in cleaning and disinfecting the rinsing section 2, and is also applicable to rinsing sections 2 heavily contaminated with oil. Therefore, using the electrolysis module 4 of this invention, while ensuring the cleaning and disinfection effect on the rinsing section 2 itself, also saves time in cleaning and disinfecting the rinsing section 2, and saves corresponding energy consumption.

[0156] Even in the heavily soiled rinsing section 2, electrolyzed water still demonstrated good cleaning performance. The inventors speculate that this is because:

[0157] (1) The electrolysis products of this application have strong oxidizing properties, while the main component of edible oil is triglycerides. The electrolysis products preferentially oxidize unsaturated fatty acids such as oleic acid and linoleic acid, resulting in the breakage of ester bonds and the generation of hydrophilic products such as glycerol, fatty acid fragments and peroxides, which can be carried away with the water flow.

[0158] (2) During the process of ozone decomposing into oxygen in the electrolytic products, the formed microbubbles adhere to the surface of the grease, thereby achieving the effect of emulsifying the grease; when cleaning the inner wall of the toilet with oil stains, the grease can be emulsified by the electrolytic products with a high oxidation-reduction potential, which can increase the applicability of the toilet seat.

[0159] In summary, this embodiment achieves efficient, environmentally friendly, and intelligent sterilization and cleaning of the rinsing section 2 by rationally arranging the position of the electrolysis module 4 and combining it with the water circulation path, filtration system, and intelligent control strategy. Furthermore, the emulsifying properties of electrolyzed water further enhance the applicability and practicality of the equipment, representing a significant technological advancement.
