Description

Technical Field

[0001] This invention belongs to the field of water makers and supply machines, specifically relating to a water maker and supply machine and a method for managing the cleanliness of its outlet. Background Technology

[0002] A water purifier / dispenser is a drinking water supply device that provides convenient and safe cold / hot drinking water. With its simple operation, easy access, and practical functions, it is widely used in homes, offices, schools, hospitals, office buildings, convenience stores, and other places, becoming an indispensable infrastructure in modern life and work. Its core function is to deeply treat the water from different sources (commonly pure water, purified water, bottled purified water, mineral water; some household models can be directly connected to tap water) through built-in heating, eliminating contamination from the water faucet exposed to the air and truly solving the harm caused by water faucet contamination. The water is then directly dispensed through the pipes, completely solving the safety issues caused by secondary contamination. This greatly improves the convenience and comfort of drinking water while addressing safety and health concerns.

[0003] Currently, most water purifiers, water generators, and water supply machines of various specifications on the market have simple pipe outlet structures that only control water flow. However, they all share a common design flaw: there is always a connecting pipe of varying length between the switching mechanism and the outlet. Due to structural limitations, this pipe cannot be completely emptied after each water output, leaving a certain amount of stagnant water. This residual water remains in the pipe for a long time, unable to circulate with fresh water from the outside, essentially providing a "breeding ground" for microbial growth.

[0004] More importantly, the water outlets of water purifiers and dispensers are mostly located in open areas outside the equipment, without dedicated sealing protection devices. They are exposed to ambient air for extended periods, directly coming into contact with dust, pollen, suspended particulate matter, and various microorganisms. In everyday use environments, whether it's a family living room, a public area of ​​an office, a school classroom, or a hospital corridor, the ambient temperature is mostly between 15-35℃. This temperature range is precisely the ideal condition for the rapid reproduction of fungi, bacteria, mold, and other microorganisms. These microorganisms can be spread through the air, attaching to the surface of the water outlet and simultaneously invading the stagnant water remaining in the pipe cavity, gradually multiplying and even forming a biofilm that is difficult to remove.

[0005] When people press the pump again, the contaminated water remaining in the pipe will flow out first, creating a breeding ground in other containers. This contamination will then directly enter the drinking cup, becoming a direct source of microbial contamination and seriously affecting the safety of the first cup of water. Long-term consumption of this contaminated water may pose potential harm to the digestive and immune systems, especially for vulnerable groups such as the elderly, children, and pregnant women. Furthermore, during daily use, people inevitably come into contact with the outer wall of the water outlet when taking water, and sweat, dust, and microorganisms from their hands will adhere to it. Simultaneously, water droplets easily splash onto the outer wall of the outlet, forming water stains. These stains retain minerals and microorganisms from the water, further adsorbing dust and bacteria from the environment. Over time, this accumulation not only affects the appearance of the water dispenser but also increases the risk of cross-infection, adversely affecting long-term health.

[0006] Beyond the drinking water safety hazards in civilian settings, the structural defects of such pipe outlets pose more prominent and potentially more serious problems in the fields of medical and laboratory water use, directly impacting medical safety and the reliability of scientific research data.

[0007] In medical settings, dedicated water supplies for special areas such as hospital rinsing, ward drinking water, intensive care units, neonatal wards, and dialysis departments have near-stringent standards for sterility and purity. These are fundamental to preventing hospital-acquired infections and ensuring patient safety. Existing water supply systems and pipes often have residual water accumulation and open, exposed structures, making them highly susceptible to bacterial, fungal, and even pathogenic bacteria growth. The resulting biofilms and microbial contaminants can directly enter the medical water supply chain with the first flow of water. For highly sensitive groups such as postoperative patients, immunocompromised individuals, and newborns, contaminated medical water can easily lead to cross-infection, gastrointestinal infections, and other hospital-acquired safety incidents, severely violating the sterility control requirements for medical water. Even when used for rinsing ordinary medical equipment or cleaning by medical staff, microbial contamination can indirectly affect standard operating procedures and amplify medical safety risks.

[0008] Laboratory water use also places extremely high demands on water purity. Whether it is physicochemical analysis, reagent preparation, precision instrument testing, or scientific research processes such as cell culture, microbial experiments, and environmental monitoring, microorganisms, impurities, and biofilms in the water can directly interfere with experimental results. When polluted water remaining in the pipe outlet lumen mixes into the experimental water, it will contaminate experimental samples, damage reagent purity, and lead to distorted test data, deviations in experimental curves, and cell culture failures. At best, this will result in wasted research materials and repeated rework; at worst, it will invalidate research conclusions and cause deviations in test results, causing irreversible impacts on high-precision scientific research such as drug development, water quality monitoring, and biological experiments.

[0009] It can be said that secondary pollution in civilian drinking water scenarios only affects daily health. However, for medical water and laboratory water, which are special scenarios with mandatory standards for water quality cleanliness and sterility, the structural defects of existing water pipe outlets are no longer simply a drinking water health issue, but have risen to the level of medical safety hazards and risks to the reliability of scientific research data. This further highlights the urgency and necessity of optimizing and improving the structure of water pipe outlets in water treatment and supply machines and thoroughly solving the problems of residual water and secondary pollution.

[0010] In addition to the aforementioned core hidden dangers, many users often neglect the cleaning and maintenance of the water outlet in daily use. They mostly focus on wiping the surface of the water purifier and water supply machine and changing the bottled water, but ignore the cleaning of the connecting pipe cavity and the water outlet. This leads to the continuous accumulation of microorganisms in the residual water and the gradual thickening of the biofilm. Even if new bottled water is replaced later, it is difficult to completely remove the pollution in the pipe cavity, forming "secondary pollution" and further amplifying the drinking safety risks. This is a common blind spot and maintenance loophole in the use of water purifiers and water supply machines.

[0011] Therefore, in response to the above-mentioned technical problems, it is necessary to provide a method for the cleanliness management of water generators and their outlets.

[0012] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0013] The purpose of this invention is to provide a water maker and water outlet cleanliness management method, which can solve the problem that after the water is discharged from the existing water maker, the remaining stagnant water inside is exposed to the ambient air for a long time, which easily breeds fungi, bacteria, mold and biofilm, thus constituting a source of microbial pollution.

[0014] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution: A water generator / supplyer includes: a main body, a rapid heating gas and / or water jet mechanism, a check valve separation mechanism, and a dual-water-storage disinfection mechanism.

[0015] In one or more embodiments of the present invention, the check valve assembly includes: a check valve positioning ball, a sheet and / or membrane, and a check valve positioning ring. The check valve positioning ball, sheet, and / or membrane are disposed within the water outlet of the pipe; the check valve positioning ring is disposed within the water outlet of the pipe.

[0017] In one or more embodiments of the present invention, the supported check valve assembly includes: a pair of supported check valve support frames, a pair of supported check valve support rods, and a supported check valve spring. The pair of supported check valve support frames are disposed within the pipe outlet; the pair of supported check valve support rods are disposed between the pair of supported check valve support frames; and the supported check valve spring is sleeved on the supported check valve support rods.

[0018] In one or more embodiments of the present invention, the support-type check valve support frame is fixedly connected to the pipe outlet nozzle, the support-type check valve support rod passes through the check valve blocking positioning ring, the support-type check spring is disposed between the support-type check valve support frame and the check valve blocking positioning ball, plate and / or membrane, and the support-type check spring is disposed on the side of the check valve blocking positioning ring near the induction coil assembly.

[0019] In one or more embodiments of the present invention, the dual water storage assembly includes: a dual water storage fixed chamber, a dual water storage pump, and a dual water storage connecting pipe. The dual water storage fixed chamber is disposed on one side of the water outlet of the pipe; the dual water storage pump is disposed on the dual water storage fixed chamber; and the dual water storage connecting pipe is disposed between the dual water storage pump and the supporting check valve rod.

[0020] In one or more embodiments of the present invention, the dual water storage fixed chamber is fixedly connected to the water production and supply machine body, the dual water storage pump is installed through the dual water storage fixed chamber, and the dual water storage connecting pipe is installed through the pipe outlet and the supporting check rod.

[0021] In one or more embodiments of the present invention, the water storage and injection assembly includes: a water storage and injection pipe and a water storage and injection pressure plate. The water storage and injection pipe is disposed on the dual water storage and fixing chambers and extends through the dual water storage and fixing chambers and the pipe outlet; the water storage and injection pressure plate is disposed inside the water storage and injection pipe.

[0022] In one or more embodiments of the present invention, the dual-water-storage disinfection mechanism further includes a heating pipe and a disinfection assembly, the disinfection assembly including: an in-chamber ultraviolet (UV) device, an ozone generator, and an in-machine UV device. The in-chamber UV device is disposed within the dual-water-storage fixed chamber; the ozone generator is disposed within the dual-water-storage fixed chamber; and the in-machine UV device is disposed within the water purifier / supplyer body.

[0023] A method for managing the cleanliness of the water outlet of a water generator / supply machine includes the following steps: S1. When there is water in the water outlet of the pipe, water will be injected into the double water storage fixed chambers through the water storage injection component. This part of water will be stored in a pair of double water storage fixed chambers under the water outlet of the pipe. S2. The water in a double-storage fixed tank is rapidly heated to boiling through the heating pipe, and the high-temperature water or steam is injected into the water outlet of the pipe through the double-storage water pump and the double-storage connecting pipe to flush the inner pipe of the water outlet. S3. Disinfect the water in another double-storage fixed tank by using an ultraviolet device and an ozone generator inside the tank, and inject ozone. The solution of water and ozone is injected into the water outlet of the pipe through the double-storage water pump and the double-storage connecting pipe to perform a secondary flushing of the inner pipe of the water outlet. S4. After rinsing, or by activating the induction coil assembly separately, the residual water in the pipe outlet is rapidly heated. The water inside is rapidly vaporized by the heating, forming a gas bomb that is sprayed out from the pipe outlet. The steam and hot water are used to rinse the water and achieve the purpose of disinfection. S5. Before each water connection or after water connection is completed and the cabinet door of the water maker / supplyer is closed, the internal ultraviolet device installed inside the water maker / supplyer will disinfect the outside of the water outlet of the pipe. S6. The cabinet door of the water supply unit is subject to conditional management and cannot be opened or closed arbitrarily. For example, it can only be opened after swiping a card or making payment. Compared with existing technologies, the water purifier and water supply machine and its outlet cleanliness management method of the present invention, through the setting of corresponding mechanisms, realizes automated self-disinfection of the water outlet before water is received. It can effectively eliminate various harmful microorganisms such as fungi, bacteria, and mold that grow inside the water outlet, and completely dismantle the biofilm that is easily formed in the pipe cavity. It fundamentally solves the problem of biological pollution caused by residual stagnant water in the water outlet of traditional water purifiers and water supply machines, eliminates the possibility of residual water becoming a drinking water safety hazard, and greatly improves the drinking safety of the first flow and the first cup of water, so that every time water is taken, the cleanliness and health of drinking water can be guaranteed from the source.

[0024] Addressing the safety risks inherent in traditional water dispenser pipes and taps, this design precisely avoids the problem of contaminated first cups of water. This is particularly beneficial for vulnerable groups such as the elderly, children, and pregnant women, effectively reducing health risks from contaminated water and ensuring reliable safety for the drinking water needs of diverse populations. Furthermore, through efficient self-disinfection, it fundamentally prevents cross-infection caused by contaminated pipe taps during daily use. It also solves the problems of pipe taps easily absorbing dust and microorganisms when exposed to the environment, as well as secondary contamination from hand contact and water splashes, comprehensively improving the hygiene of drinking water.

[0025] This automated self-disinfection mode before water dispensing eliminates the need for manual cleaning, perfectly addressing the common user oversight and operational errors associated with cleaning and maintaining water pipes and outlets, thus reducing the possibility of repeated contamination. Whether used by a single person in a household or shared by multiple people in public settings such as offices, schools, and hospitals, the water purifier / supply machine maintains excellent hygiene, reducing daily maintenance difficulties and ensuring long-term drinking water safety. This makes the water purifier / supply machine more suitable for various scenarios and facilitates its long-term continuous use.

[0026] Various water purifiers, dispensers, and supply machines have water outlets that are some distance from the switch, resulting in a certain amount of water remaining between the outlet and the switch. This open space provides ideal conditions for fungal and bacterial contamination and growth. To address this issue, we employ a four-pronged disinfection technique: 1. A heating device is installed on the water outlet. Each time the switch is turned on, boiling water is released to rinse the outlet. 2. Before each switch is turned on, an induction coil rapidly heats the pipe cavity behind the switch, causing the local water temperature to rise quickly and vaporize, forming a gas ejected from the outlet. This steam and hot water then rinse the outlet, achieving disinfection. 3. Before the switch is turned on, ultraviolet light and ozone are used to infuse the drinking water in the dual-storage water components with ozone. Turning on the switch allows for rinsing with an ozone and water solution, achieving disinfection. 4. After the water purifier / supply machine body forms a sealed chamber through the door, ultraviolet light is installed inside. Disinfection is completed before the door is opened for water collection, preventing potential harm. Attached Figure Description

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0031] like Figures 1 to 8As shown, the water maker and supply unit in one embodiment of the present invention mainly comprises four core components: the water maker and supply unit body 1, the rapid heating gas and / or water bomb mechanism 2, the check valve separation mechanism 3, and the dual water storage disinfection mechanism 4. These mechanisms work together to achieve efficient and clean management of the water outlet, ensuring drinking water safety. The water maker and supply unit body 1, as the basic load-bearing component of the entire device, has a pair of symmetrically distributed pipe outlets 11 fixedly installed inside. The inner walls of the pipe outlets 11 are smooth and without dead corners, effectively reducing bacterial growth. They also possess good thermal conductivity, adapting to subsequent heating and disinfection requirements, thus providing a basic carrier for the implementation of the clean management method.

[0032] The rapid-heating gas and / or water jet mechanism 2, as the core mechanism for achieving high-temperature gas jet flushing and disinfection, is structurally designed to meet the installation requirements of the water outlet 11. It mainly includes an induction coil assembly 21 located outside the water outlet 11 and an induction coil protective shell 22 fitted over the induction coil assembly 21. The induction coil protective shell 22 effectively protects the induction coil assembly 21 from external dust and moisture corrosion, extending its service life. It also provides insulation protection, preventing potential leakage hazards during use and ensuring safe equipment operation.

[0033] The check valve separation mechanism 3 is installed inside the water outlet 11 of the pipeline. It is mainly used to prevent the backflow of drinking water and disinfected wastewater in the pipeline and avoid cross-contamination. Specifically, it includes a check valve barrier component 31 installed inside the water outlet 11 and a support check valve component 32 also installed inside the water outlet 11. The two work together to form a double check valve protection structure, further improving the drinking water safety. The dual water storage disinfection mechanism 4 is located on the lower side of the water outlet 11. It is mainly used to store drinking water for disinfection and rinsing, and to complete pretreatment operations such as disinfection and heating. It includes a pair of symmetrically arranged dual water storage components 41 and a water storage injection component 42 installed on the dual water storage components 41. The pair of dual water storage components 41 have clear division of labor, respectively undertaking the functions of hot water rinsing and ozone disinfection rinsing, ensuring the rinsing and disinfection effect.

[0034] The core working principle of the induction coil assembly 21 is electromagnetic induction eddy current heating, a typical application of induction heating technology in the field of water supply equipment. Its operation is characterized by high efficiency, energy saving, and zero pollution. Specifically, when an external power source supplies a high-frequency alternating current to the induction coil assembly 21, an alternating magnetic field with constantly changing intensity and direction is rapidly generated around the assembly. This magnetic field precisely covers the outer wall of the water outlet 11, placing the outlet 11 completely within its range. According to the law of electromagnetic induction, the alternating magnetic field penetrates the metal wall of the outlet 11 and acts inside, causing a closed induced current, i.e., eddy current, to be spontaneously induced inside the outlet 11 in a vortex-like distribution. The flow direction of the eddy current is perpendicular to the direction of change of the alternating magnetic field and is concentrated on the inner wall and surface area of ​​the outlet 11.

[0035] Since the water outlet 11 is made of metal, and metal itself has inherent resistance, the resistance is related to the metal material, cross-sectional dimensions, and temperature. The resistance of the water outlet 11 is moderate, ensuring both effective generation of eddy currents and rapid heat conversion. When the high-speed flowing eddy current overcomes the resistance inside the water outlet 11, it directly converts electrical energy into heat energy according to Joule's law, causing the water outlet 11 to heat up rapidly and achieve self-heating. It is worth noting that in this heating method, the induction coil assembly 21 only acts as a magnetic field generating component and generates almost no heat itself. All the heat is concentrated inside the heated water outlet 11, avoiding heat waste. Therefore, the thermal efficiency is high, far exceeding that of traditional resistance heating methods.

[0036] Meanwhile, the current frequency directly affects the heating effect, and the two are positively correlated: the higher the frequency, the more concentrated the eddy currents are on the metal surface, forming a surface heating effect, which is suitable for quickly raising the surface temperature of the pipe outlet 11; the lower the frequency, the deeper the heat penetration, which is suitable for overall heating of the pipe outlet 11. In accordance with the clean management requirements of this invention, high-frequency current is used for heating, which can achieve rapid temperature rise while ensuring that the heat is concentrated on the inner wall of the pipe outlet 11, achieving an ideal heating and disinfection effect. This heating method also has significant advantages such as fast heating speed, easy temperature control, and no pollution, and will not produce any harmful gases or impurities, thus avoiding secondary pollution of drinking water.

[0037] Based on the structural design of the above-mentioned mechanisms, the water generator and its outlet clean management method in this embodiment are clear, efficient and fast. The specific steps are as follows: When there is drinking water in the water outlet 11, the water injection component 42 installed on the dual water storage component 41 will automatically start and inject an appropriate amount of drinking water into the dual water storage component 41. This part of drinking water will be stored in a pair of dual water storage components 41 below the water outlet 11 through the diversion structure, ensuring that there is sufficient water in both dual water storage components 41, in preparation for subsequent flushing and disinfection operations. One of the dual water storage components 41 is equipped with a heating tube 43. The heating tube is insulated and encapsulated to prevent direct contact with drinking water and contamination. After the heating tube 43 is activated, the drinking water in the dual water storage component 41 can be quickly heated to a high temperature. The high-temperature drinking water will be quickly injected into the water outlet 11 under the action of the dual water storage pump, and the inner tube of the water outlet 11 will be flushed for the first time. The impact force of the high-temperature water flow will wash away the impurities, scale and some bacteria attached to the inner wall of the inner tube, and achieve preliminary cleaning.

[0038] After the first hot water rinse, the disinfection component 44 on another dual-water storage component 41 is activated to disinfect the drinking water within that component. Simultaneously, an appropriate amount of ozone is injected into the water via an ozone generator. After the ozone mixes thoroughly with the drinking water, a highly oxidizing disinfectant solution is formed. This solution is then injected into the water outlet 11 through the connecting pipe of the dual-water storage component 41, providing a secondary rinse to the inner pipe of the outlet 11. Ozone has a strong bactericidal and disinfecting effect, effectively killing bacteria, viruses, spores, and other harmful microorganisms in the water. It also decomposes residual organic matter on the inner wall of the pipe, further improving the cleanliness of the pipe and preventing bacterial growth.

[0039] After the second rinsing, a small amount of disinfectant solution and drinking water will remain in the water outlet 11. At this time, the induction coil assembly 21 is activated to rapidly heat the remaining drinking water in the water outlet 11. The remaining drinking water vaporizes rapidly under high temperature, forming a high-temperature and high-pressure gas bomb. Under the action of internal air pressure, the gas bomb is rapidly sprayed out from the water outlet 11. During the process, the inner pipe of the pipe is rinsed again. The high temperature and impact force of the steam are used to thoroughly remove the residual water and disinfectant solution in the pipe, while achieving high-temperature disinfection, further ensuring the cleanliness of the water outlet 11.

[0040] To achieve comprehensive cleanliness management, after each water dispensing process and the cabinet door of the water purifier / supply unit 1 is closed, the disinfection component 44 installed inside the water purifier / supply unit 1 automatically activates to disinfect the exterior of the water outlet 11, preventing bacteria growth from splashed water droplets during dispensing and achieving comprehensive disinfection inside and outside the outlet. In this embodiment, the entire rinsing and disinfection process can be completed within 3 seconds, which is highly efficient. After opening the water purifier / supply unit 1, users can directly dispense water for drinking without waiting. Simultaneously, to enhance the safety of the equipment, a child lock function can be installed. After pressing the water dispensing button on the water purifier / supply unit 1, the cabinet door will only open after 3 seconds, preventing children from accidentally touching high-temperature components or the water outlet and causing burns or other injuries. Furthermore, the water purifier / supply unit 1 is also equipped with a wastewater tank to collect contaminated drinking water generated during the rinsing and disinfection process. The wastewater tank can be disassembled and cleaned at any time to prevent the wastewater from accumulating bacteria over a long period, further ensuring the overall cleanliness of the equipment.

[0041] like Figures 1 to 5 As shown, the check valve barrier assembly 31, as the core component of the check valve separation mechanism 3, mainly includes: a check valve positioning ball, plate, and / or membrane 311 and a check valve positioning ring 312. These two components work together to achieve the sealing and check valve function of the pipe outlet 11. The check valve positioning ball, plate, and / or membrane 311 is disposed inside the pipe outlet 11, and its diameter matches the inner diameter of the pipe outlet 11, allowing it to slide freely within the pipe. Simultaneously, its smooth surface ensures a tight fit with the check valve positioning ring 312. The placement of the check valve positioning ball, plate, and / or membrane 311 precisely seals the check valve positioning ring 312, effectively separating the drinking water within the pipe outlet 11. This prevents the drinking water at the outlet of the pipe outlet 11 from flowing back into the pipe, preventing external bacteria from entering the pipe and causing cross-infection.

[0042] Simultaneously, when the outlet of the pipe nozzle 11 is heated by the induction coil assembly 21, the liquid inside the pipe rapidly vaporizes, and the internal air pressure rises rapidly. At this time, the check valve positioning ball, plate, and / or membrane 311, under the action of air pressure, will tightly fit with the check valve positioning ring 312, further enhancing the sealing performance and preventing the vapor and contaminated drinking water from flowing back to the clean area on the other side of the pipe, effectively improving the safety of drinking water. The check valve positioning ring 312 is fixedly installed inside the pipe nozzle 11, and its inner side is provided with an arc-shaped groove that matches the check valve positioning ball, plate, and / or membrane 311. It can cooperate with the check valve positioning ball, plate, and / or membrane 311 to effectively seal the pipe nozzle 11, ensuring that the drinking water on both sides of the pipe nozzle 11 does not mix, and ensuring the orderly progress of the rinsing and disinfection process.

[0043] When the water outlet switch of the water purifier / supply unit 1 is pressed, the water pressure in the pipeline will naturally push the check valve positioning ball, plate, and / or membrane 311, causing it to separate from the check valve positioning ring 312. At this time, the water outlet 11 is in a clear state, and drinking water can flow out normally. The precise matching between the check valve positioning ring 312 and the check valve positioning ball, plate, and / or membrane 311 significantly improves the sealing performance between them, reducing the possibility of leakage between the check valve positioning ball, plate, and / or membrane 311 and the check valve positioning ring 312, further enhancing the safety of drinking water. The check valve positioning ring 312 and the water outlet 11 are fixedly connected, ensuring a firm connection that is not easily detached and guaranteeing long-term stable operation. In addition, the check-block positioning ball, sheet and / or membrane 311 is also wrapped with a check-block sealing layer 313. This sealing layer is soft and has excellent sealing performance, which can further improve the sealing performance between the check-block positioning ring 312 and the check-block positioning ball, sheet and / or membrane 311, effectively preventing the mixing of drinking water on both sides of the water outlet 11. This not only ensures the normal operation of the dual water storage disinfection mechanism 4, but also further improves the overall safety of the equipment.

[0044] like Figures 1 to 6 As shown, the support-type check valve assembly 32 is mainly used to support and guide the check valve blocking positioning ball, sheet, and / or membrane 311, ensuring its stable sliding and improving the check valve effect. Specifically, it includes: a pair of support-type check valve support frames 321, a pair of support-type check valve support rods 322, and a support-type check valve spring 323. The pair of support-type check valve support frames 321 are symmetrically arranged inside the pipe outlet 11, with a robust structure, providing stable support for the support-type check valve support rods 322. This effectively reduces the probability of the support-type check valve support rods 322 tilting or deforming, improving the stability of the support-type check valve support rods 322, and also reducing the probability of the support-type check valve support rods 322 detaching from the support frames, ensuring the reliability of the entire support structure.

[0045] A pair of supporting check rods 322 are arranged parallel to each other between a pair of supporting check brackets 321, and the supporting check rods 322 also penetrate through the supporting check brackets 321. This not only further improves the installation stability of the dual water storage connecting pipe 413, but also provides convenient conditions for the installation of the dual water storage connecting pipe 413. At the same time, the supporting check rods 322 can also provide precise guidance for the sliding of the check-out blocking positioning ball, plate and / or membrane 311. The check-out blocking positioning ball, plate and / or membrane 311 is provided with through holes that match the support rods, and can slide freely along the support rods. This effectively reduces the probability of the check-out blocking positioning ball, plate and / or membrane 311 deviating from the track and shifting, so that the check-out blocking positioning ball, plate and / or membrane 311 can better separate the drinking water on both sides of the pipe outlet 11, or slide under water pressure, ensuring that the pipe outlet 11 can output water normally.

[0046] A support-type check spring 323 is sleeved on a support-type check support rod 322. It possesses excellent elasticity, and its elastic coefficient is precisely calculated. This allows it to moderately compress the check-type barrier positioning ball, plate, and / or membrane 311, further enhancing the sealing performance between the check-type barrier positioning ball, plate, and / or membrane 311 and the check-type barrier positioning ring 312, ensuring a reliable check. Simultaneously, when the water pressure decreases on the side of the check-type barrier positioning ball, plate, and / or membrane 311 away from the support-type check spring 323, the support-type check spring 323 can quickly rebound, pushing the check-type barrier positioning ball, plate, and / or membrane 311 back into contact with the check-type barrier positioning ring 312, achieving rapid sealing and reducing the possibility of leakage from the check-type barrier positioning ball, plate, and / or membrane 311.

[0047] The support-type check valve support 321 is fixedly connected to the pipe outlet 11, which effectively improves the stability of the support-type check valve support 321, reduces the probability of it detaching from the pipe, and thus improves the stability of the support-type check valve support rod 322, reducing the possibility of tilting or deformation of the support rod and improving the balance of the support-type check valve support rod 322. The support-type check valve support rod 322 is installed through the check valve blocking positioning ring 312 to ensure the accuracy of the guiding action; the support-type check spring 323 is installed between the support-type check valve support 321 and the check valve blocking positioning ball, plate and / or membrane 311, and is located on the side of the check valve blocking positioning ring 312 closer to the induction coil assembly 21. This arrangement not only facilitates the normal contraction and rebound of the support-type check spring 323, but also further improves the stability of the support-type check spring 323. Through the supporting action of the support-type check valve support rod 322, the probability of the support-type check spring 323 detaching from the support rod is effectively reduced, ensuring its long-term stable operation.

[0048] like Figures 1 to 7As shown, the dual water storage component 41, as the core storage component of the dual water storage disinfection mechanism 4, is mainly used to store drinking water for hot water rinsing and drinking water for disinfection, respectively. Specifically, it includes: a dual water storage fixed chamber 411, a dual water storage pump 412, and a dual water storage connecting pipe 413. The dual water storage fixed chamber 411 is located below the water outlet 11 of the pipe, ensuring the safety of the drinking water. Its capacity is rationally designed to meet the water consumption requirements for a single rinse and disinfection. The two dual water storage fixed chambers 411 have different installations and clear functions: one dual water storage fixed chamber 411 contains a heating tube 43 to heat the drinking water to a high temperature for hot water rinsing; the other dual water storage fixed chamber 411 contains an internal ultraviolet device 441 and an ozone generator 442 to disinfect the drinking water and inject ozone for disinfection rinsing.

[0049] The dual water storage fixed chamber 411 not only facilitates the installation and fixation of the heating pipe 43, the internal ultraviolet device 441, and the ozone generator 442, but also effectively prevents drinking water leakage, ensuring cleanliness during equipment operation. When needed, the water injection component 42 can continuously supply clean drinking water from the pipe outlet 11, replenishing the dual water storage fixed chamber 411 with water at any time, ensuring continuous rinsing and disinfection operations without frequent manual water addition. The dual water pump 412 is located on the upper side of the dual water storage fixed chamber 411, with moderate power, ensuring sufficient water pressure while avoiding excessive noise. Its main function is to extract drinking water from the dual water storage fixed chamber 411 and inject it into the pipe outlet 11 through the dual water storage connecting pipe 413 to achieve the rinsing operation.

[0050] It should be noted that the water injection component 42 receives water from the side of the check-barrier positioning ball, plate, and / or membrane 311 closest to the water supply unit 1. The drinking water on this side is clean, uncontaminated drinking water, ensuring the cleanliness of the water stored in the dual water storage fixed tanks 411. The drinking water injected into the dual water storage connecting pipe 413 is injected into the other side of the check-barrier positioning ball, plate, and / or membrane 311, which is the outlet side of the pipe outlet 11. This ensures that the flushing water flow can directly rinse the inner pipe, achieving the purpose of cleaning and disinfection. The dual water storage connecting pipe 413 is located between the dual water storage pump 412 and the supporting check-barrier support rod 322. It is flexible and easy to bend, facilitating installation. Its two ends are sealed to the dual water storage pump 412 and the supporting check-barrier support rod 322 respectively, preventing leakage. The dual water storage fixed chamber 411 is fixedly connected to the water generator body 1, and the connection is firm; the dual water storage pump 412 is installed through the dual water storage fixed chamber 411, and its inlet extends deep into the bottom of the chamber to ensure that the drinking water in the chamber can be fully extracted; the dual water storage connecting pipe 413 is installed through the pipe outlet 11 and the supporting check rod 322 to ensure that the water flow can be smoothly injected into the pipe outlet 11.

[0051] like Figures 1 to 4 As shown, the water injection component 42 is mainly used to inject clean drinking water into the dual water storage fixed chamber 411. Specifically, it includes a water injection pipe 421 and a water injection pressure plate 422. The water injection pipe 421 is located on the upper side of the dual water storage fixed chamber 411 and passes through both the dual water storage fixed chamber 411 and the water outlet 11. It is corrosion-resistant and not prone to aging, ensuring the cleanliness of the drinking water. Its main function is to connect the water outlet 11 with the dual water storage fixed chamber 411, injecting clean drinking water from the water outlet 11 into the dual water storage fixed chamber 411, replenishing the dual water storage fixed chamber 411 with water at any time, and ensuring the smooth operation of rinsing and disinfection.

[0052] The water injection pressure plate 422 is installed inside the water injection pipe 421. It has excellent elasticity and its working principle is similar to the opening structure of a beverage bottle, with unidirectional conduction characteristics. Specifically, when drinking water in the pipe outlet 11 wants to break through the water injection pressure plate 422 and enter the dual water storage chamber 411, the water pressure in the pipe outlet 11 needs to be greater than the water pressure in the dual water storage chamber 411. At this time, the pressure plate will be pushed open by the water pressure, and the drinking water will be smoothly injected into the chamber. When the dual water storage chamber 411 is full of drinking water, the water pressure in the chamber is equal to the water pressure in the pipe outlet 11. The water injection pressure plate 422 will automatically close, preventing drinking water from continuing to be injected. At the same time, it can also prevent water in the dual water storage chamber 411 from flowing back into the pipe outlet 11, ensuring the independence and cleanliness of the water source in the chamber.

[0053] like Figures 1 to 6 As shown, the dual-water-storage disinfection mechanism 4 also includes a heating tube 43 and a disinfection component 44, which correspond to the two dual-water-storage fixed chambers 411 respectively, working together to achieve hot water rinsing and disinfection rinsing functions. The heating tube 43 is insulated to prevent direct contact between the heating tube and drinking water, thus preventing the precipitation of metal ions and causing drinking water pollution. It also provides insulation protection to avoid the risk of electric leakage. The power of the heating tube is reasonably designed to quickly heat the drinking water in the dual-water-storage fixed chambers 411. When the water purifier / supply unit 1 is connected to the power supply, the heating tube can continuously heat the drinking water in the chamber to the preset heat preservation temperature, making it easy to start the rinsing operation at any time and improving the rinsing efficiency. When high-temperature rinsing is required, the heating tube can quickly heat the drinking water to a high temperature to ensure the disinfection effect of high-temperature rinsing.

[0054] The disinfection component 44 is the core component for achieving disinfection rinsing, and it specifically includes: an in-chamber ultraviolet (UV) device 441, an ozone generator 442, and an in-machine UV device 443. The in-chamber UV device 441 is located inside the dual-water storage chamber 411. The UV light emitted by it has a strong bactericidal and disinfecting effect, effectively killing harmful microorganisms such as bacteria, viruses, and spores in the water. While disinfecting drinking water, it can also decompose organic matter in the water, ensuring cleaner water flow when rinsing the pipe outlet 11. This effectively reduces the possibility of bacteria remaining on the inner wall of the pipe outlet 11, further improving the safety of drinking water.

[0055] An ozone generator 442 is installed inside the dual-water storage chamber 411, working in conjunction with the ultraviolet (UV) device 441 within the chamber. It generates a high concentration of ozone, which is injected into the drinking water within the dual-water storage chamber 411 through a pipe. After thorough mixing with the drinking water, it forms a highly oxidizing disinfectant solution. This disinfectant solution, after rinsing the water outlet 11, not only kills residual bacteria on the inner wall of the pipe but also decomposes organic matter and scale adhering to the inner wall, further improving the cleanliness of the pipe and preventing bacterial growth. The UV device 443 is symmetrically arranged inside the water purifier / supply unit 1, located on both sides of the water outlet 11. It uses small UV lamps to quickly disinfect the outer shell of the water outlet 11. For water droplets splashed onto the outer shell during water dispensing, the UV light effectively kills bacteria in the droplets, preventing bacterial growth after the droplets dry. This achieves comprehensive disinfection of the inside and outside of the water outlet 11, ensuring the overall cleanliness of the equipment.

[0056] A method for managing the cleanliness of the water outlet of a water generator / supply machine includes the following steps: S1. When drinking water is present in the water outlet 11, the water injection component 42 will inject drinking water into the double water storage fixed chambers 411. This portion of drinking water will be stored in a pair of double water storage fixed chambers 411 below the water outlet 11.

[0057] S2. The drinking water in a double-storage fixed tank 411 is rapidly heated to boiling through the heating pipe 43, and the high-temperature drinking water is injected into the pipe outlet 11 through the double-storage water pump 412 and the double-storage connecting pipe 413 to flush the inner pipe of the pipe outlet 11.

[0058] S3. The drinking water in another double-storage fixed tank 411 is disinfected by the ultraviolet device 441 and ozone generator 442 in the tank, and ozone is injected. The solution of drinking water and ozone is injected into the pipe outlet 11 through the double-storage water pump 412 and the double-storage connecting pipe 413 to perform a secondary flushing of the inner pipe of the pipe outlet 11.

[0059] S4. After rinsing, or by activating the induction coil assembly 21 separately, the residual drinking water in the pipe outlet 11 is rapidly heated. The drinking water inside is rapidly vaporized by heating, forming a gas bomb, which is sprayed out from the pipe outlet 11. The steam and hot water are used to rinse the water, achieving the purpose of disinfection.

[0060] S5. After each water supply is completed and the cabinet door of the water maker 1 is closed, the internal ultraviolet device 443 installed inside the water maker 1 will disinfect the outside of the water outlet 11. S6. The cabinet door of the water supply unit is subject to conditional management and cannot be opened or closed arbitrarily. For example, it can only be opened after swiping a card or making payment. It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics.
