Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purification, in particular to a faucet front-end waterway structure. BACKGROUND

[0002] With the improvement of people's living standards and the enhancement of health awareness, household water purifiers have become key electrical equipment for many families to ensure water safety. The core working principle is to remove impurities, residual chlorine, heavy metals, bacteria, viruses and other harmful substances in tap water through physical filtration (such as PP cotton, activated carbon) and chemical purification (such as RO reverse osmosis membrane, ultrafiltration membrane) and other means to provide clean direct drinking water. For example, suspended particulate matter, organic matter and part of the odor substances in the water are removed by physical filtration materials such as PP cotton and activated carbon, and then the harmful microorganisms and dissolved pollutants such as heavy metal ions, bacteria and viruses in the water are intercepted by chemical purification components such as RO reverse osmosis membrane and ultrafiltration membrane, thereby providing clean water source for users to drink directly.

[0003] However, the current design concept of traditional water purifiers mainly focuses on the high-efficiency removal ability of the filter core system to the pollutants at the inlet end, but generally fails to fully consider the secondary pollution risk hidden in the dead water area existing in the internal part of the water purifier, especially in the key part of the faucet interface. Under the intermittent working mode of the water purifier, when the user stops taking water, a certain amount of water will remain in these dead water areas, and due to the lack of continuous water flow flushing and effective bacteriostatic measures, this area is prone to become a breeding ground for bacteria, algae and other microorganisms. With the passage of time, the large-scale reproduction of microorganisms not only may cause the water quality to decrease and produce odor, but also may pose a potential threat to the user's drinking water health, which has become an important technical bottleneck restricting the further improvement of user experience and the protection of drinking water safety of household water purifiers.

[0004] Therefore, it is urgent to provide a new solution that can effectively solve the pollution problem of the dead water area in the internal part of the water purifier to make up for the shortcomings of the prior art and improve the hygiene and safety of household water purifiers.

[0039] The present application discloses a faucet front-end waterway structure.

[0040] Please refer to Figure 1 An embodiment of the faucet front-end waterway structure provided in the present application includes:

[0041] The water outlet waterway 10, the hot water waterway 20, the hot water generating device 1, the microbial treatment module 3, and the waterway control assembly.

[0042] One end of the water outlet waterway 10 is used for connecting the water outlet faucet 30; the two ends of the hot water waterway 20 are respectively connected to the two ends of the water outlet waterway 10; the microbial treatment module 3 is connected in series in the water outlet waterway 10; the hot water generating device 1 is installed in the hot water waterway 20, and is used for generating hot water and enabling the hot water to flow in circulation between the hot water waterway 20 and the water outlet waterway 10; and the waterway control assembly is used for controlling the on-off between the hot water waterway 20 and the water outlet waterway 10, and / or controlling the on-off between the water outlet waterway 10 and the water outlet faucet 30.

[0043] The faucet front-end waterway structure designed in the present application has the following beneficial effects:

[0044] 1、Microbial treatment module 3 is connected in series in the outlet water circuit 10 and located in the front end of the faucet, which can intercept and / or kill bacteria in normal temperature water or hot water, directly solve the problem of bacterial growth caused by residual moisture in the dead water area of the traditional water purifier faucet interface, ensure the cleanliness of the outlet water, and improve the safety of drinking water health.

[0045] 2、The hot water circuit 20 and the outlet water circuit 10 form a circulation, and the hot water generated by the hot water generating device 1 kills the bacteria intercepted and / or killed on the microbial treatment module 3 through circulation, prevents the bacteria from forming a film to block the module, effectively prolongs the service life of the microbial treatment module 3, solves the problem of easy blockage of the microbial treatment module 3 in the traditional water purifier, and also solves the problem of affecting the outlet water speed due to blockage.

[0046] 3、Through the sterilization effect of circulating hot water, the cleanliness effect of the water circuit structure is enhanced, further cleaning the bacteria in the outlet water circuit 10 and the dead water area, and improving the overall waterway hygiene safety.

[0047] 4、The water circuit control assembly can flexibly control the hot water circulation or the outlet water on-off, ensure the start of the hot water circulation when working intermittently (such as after stopping water taking), process the microbial treatment module 3 and the water circuit, reduce the bacterial growth of residual moisture, make up for the lack of effective antibacterial measures of the traditional water purifier, improve the hygiene safety of the outlet water quality, and improve the user's drinking water experience.

[0048] The above is an embodiment one of the faucet front-end waterway structure provided by the embodiment of the present application, and the following is an embodiment two of the faucet front-end waterway structure provided by the embodiment of the present application, please refer to Figure 1 .

[0049] Further, the microbial treatment module 3 is one or a combination of a bacteria interception module and a bacteria removal module.

[0050] When the microorganism treatment module 3 is a bacteria blocking module, it can physically block bacteria and other microorganisms in the water through special filter materials or structures, allowing only water molecules and other small molecular substances to pass through, blocking bacteria before the module to prevent them from entering the subsequent water path. This bacteria blocking module has high interception efficiency and stability, can effectively block bacteria for a long time, and ensure the hygiene of the outlet water. When the microorganism treatment module 3 is a bacteria removal module, it can use various bacteria removal methods, such as ultraviolet sterilization, ozone sterilization, silver ion sterilization, etc. Taking ultraviolet sterilization as an example, the bacteria removal module is internally provided with ultraviolet lamps, which can destroy the DNA or RNA structure of bacteria when the water flows through, so as to achieve the purpose of bacteria removal. Ozone sterilization uses the strong oxidizing property of ozone to chemically react with bacteria to kill them. Silver ion sterilization combines silver ions with bacterial cell membranes or enzymes to destroy the normal physiological functions of bacteria and achieve the effect of bacteria removal. If the microorganism treatment module 3 is a combination of a bacteria blocking module and a bacteria removal module, it can exert the advantages of both. The bacteria blocking module first intercepts most of the bacteria to reduce the processing pressure of the subsequent bacteria removal module; then the bacteria removal module completely eliminates the remaining bacteria to further improve the safety and hygiene of the outlet water. This combination can more comprehensively and effectively treat microorganisms in water, providing users with the ultimate safety guarantee for water use.

[0051] Further, as shown in Figure 1 The hot water generating device 1 includes a heater 11 and a water pump 12; the water pump 12 and the heater 11 are installed in the hot water path 20.

[0052] The heater 11 is used to heat the water to a temperature (such as 95°C) that can kill bacteria and other microorganisms. The water pump 12 is responsible for providing power to push the hot water to circulate between the hot water path 20 and the outlet water path 10. When the water pump 12 is started, the hot water will start from the hot water generating device 1, flow into the outlet water path 10 along the hot water path 20, and then return to the hot water generating device 1, forming a circulating loop.

[0053] Further, the heater 11 is an independent heater or a contained heater.

[0054] The independent heater is a heater that only has heating function, which directly acts on the hot water path 20, which can be an electric heating wire, etc.

[0055] The storage type heater has a certain volume of the heater, which can store a certain amount of water for heating, such as a hot tank; the advantage of the storage type heater compared with the independent type heater is that it can store a certain amount of hot water to ensure continuous hot water supply for a period of time. For scenes with large water consumption or continuous use of hot water, the storage type heater is more suitable. In actual application, appropriate heater types can be selected according to specific use requirements and scenes, without limitation.

[0056] Further, as shown in Figure 1 , for the waterway control assembly design, a diverter valve 21 is included; one end of the hot water line 20 is connected to one end of the outlet water line 10 and the outlet faucet 30 through the diverter valve 21. The diverter valve 21 is a three-way diverter valve, and the three connection ends are used to connect the hot water line 20, the outlet water line 10 and the outlet faucet 30, respectively, to realize the switching control of the conduction of the outlet water line 10 and the hot water line 20, or the conduction of the outlet water line 10 and the outlet faucet 30. Through the switching of the diverter valve 21, the direction of the water flow can be accurately controlled to meet the needs of different use scenarios. For example, when hot water circulation sterilization is needed, the diverter valve 21 can be switched to a state in which the hot water line 20 and the outlet water line 10 are in conduction, so that the hot water circulates in these two water lines; when the user needs to use water, the diverter valve 21 can be switched to a state in which the outlet water line 10 and the outlet faucet 30 are in conduction, so that the water flows out of the outlet faucet 30 smoothly.

[0057] In addition, the waterway control assembly can also include two on-off valves, which are connected in series on the outlet water line 10 and the hot water line 20, respectively. The on-off of the two on-off valves can also realize waterway switching control, but compared with the diverter valve design, this way needs more valves, therefore, the diverter valve design is preferred; of course, those skilled in the art can make changes and designs according to actual needs, without limitation.

[0058] Further, as shown in Figure 1 , the waterway control assembly further includes a check valve 22; the check valve 22 is connected in series on the hot water line 20 and located between the output end of the hot water generating device 1 and the outlet water line 10. The setting of the check valve 22 can effectively prevent the backflow of hot water and ensure that the hot water circulates between the hot water line 20 and the outlet water line 10 in the predetermined direction. When the hot water generating device 1 outputs hot water, the check valve 22 allows the hot water to flow normally to the outlet water line 10; when unexpected situations such as pressure fluctuations occur, which may cause the backflow of hot water, the check valve 22 will automatically close to prevent the reverse flow of hot water, thereby ensuring the normal operation of the entire waterway structure and the stability of the hot water circulation.

[0059] Further, a waterway board is also included; the outlet water line 10 and the hot water line 20 are at least integrated on the waterway board, and all the waterways involved in this application can be designed in an integrated manner on the waterway board.

[0060] Using a modular waterway plate formed by one-piece injection molding to replace the traditional complex waterway composed of multiple quick connectors and hoses can greatly reduce the number of connection points and fundamentally eliminate the microorganisms breeding in the joint gaps. Meanwhile, the one-piece structure of the waterway plate makes the waterway layout more compact and reasonable, reduces the space occupied by the waterway, and improves the integration and stability of the entire waterway structure. Moreover, the one-piece injection molding process can ensure that the flow channel surface inside the waterway plate is smoother, reducing water flow resistance, improving water flow efficiency, and further reducing the possibility of bacteria and impurities attaching and accumulating in the waterway.

[0061] Further, the water purifier further comprises a dosing device; the dosing device comprises a micro-injection assembly and / or an electrolysis assembly.

[0062] The micro-injection assembly is used to inject sterilization substances into the waterway of the waterway structure in front of the faucet; the sterilization substances can be low-concentration food-grade peroxide water solution / ozone, and the micro-injection assembly comprises a micro-metering pump, which injects the peroxide water solution / ozone into the waterway, and the sterilization is decomposed into water and oxygen. This method can efficiently kill bacteria and viruses in the waterway without introducing harmful residues, and enhance the cleaning effect of the waterway.

[0063] The electrolysis assembly is used to perform micro-electrolysis on the water flow in the waterway of the waterway structure in front of the faucet. The electrolysis assembly comprises an electrode arranged on the relevant waterway to perform micro-electrolysis on the water flow, generate hydroxyl radicals with sterilization activity and a small amount of active chlorine, and the active substances rapidly decay after the electrolysis is stopped. These active substances generated by micro-electrolysis can effectively kill bacteria and microorganisms in the waterway, and since the active substances rapidly decay, there is no harmful residue in the water, ensuring the safety of the water quality.

[0064] The two assemblies of the dosing device can be used alone or combined according to actual needs to achieve the best sterilization effect.

[0065] Although there are some water purifiers with "sterilization" function on the market, the technical solutions of these water purifiers often have limitations:

[0066] Single ultraviolet sterilization: Most of them use rear-end ultraviolet (UV) sterilization lamps. This method belongs to "point-type" disinfection, which can only kill the bacteria in the instantaneous water flowing through the lamp tube cavity, and is almost ineffective for the biofilm attached to the surface of the filter element, the inner wall of the water storage barrel, and the wall of the long waterway pipeline. Once the machine is stopped, bacteria will quickly reproduce in these areas. Chemical disinfectant residue risk: Some solutions propose to periodically add chemical disinfectants (such as ozone and chlorine-containing preparations). Although this method has a certain effect, it is easy to produce by-products, which brings the risk of chemical residues, affects the taste and safety of water, and is complex to operate, which is not suitable for daily maintenance by household users.

[0067] The waterway structure designed in the application can solve the above-mentioned problems existing in the prior art. Through the design of the internal circulation waterway, the pure water waterway is in a flowing state, and the microorganism treatment module 3 in the waterway system can 100% intercept bacteria, and then kill the intercepted bacteria through 95 DEG C hot water circulation. Through the synergistic application and safe control of physical / quasi-physical sterilization medium, a "closed loop full pipeline circulation sterilization and killing" system is constructed, and the "sterile" paradigm shift from "passive treatment" to "active maintenance" is realized. In the future development, the waterway structure of the application will be widely used in more scenes such as families and businesses, and will promote the entire water purification industry to develop in a more healthy and environmentally friendly direction.

[0068] The above describes in detail the faucet front-end waterway structure provided by the application. For those skilled in the art, according to the idea of the embodiment of the application, the specific implementation and application range will be changed. In view of the above, the content of the specification should not be understood as a limitation of the application.
