Detailed Implementation
[0038] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.
[0039] A water purification system is a household or commercial device used to purify water. It removes impurities, harmful substances, and odors from water through various filtration technologies, thereby providing safer and healthier drinking water.
[0040] In related technologies, water always remains in the first tank and pipeline of water purification equipment, especially in the pipeline between the first tank and the water faucet, particularly the section from the inlet to the outlet of the faucet. This section cannot be effectively sterilized and flushed, thus the bacterial count in the user's drinking water cannot be effectively controlled, affecting the user's health. Therefore, this utility model provides a water purification device that can flush the pipeline between the first tank and the water components, reducing the bacterial count in the user's drinking water and achieving healthy drinking water.
[0041] Therefore, this utility model provides a water purification device 100 that can directly clean the water outlet of the faucet assembly 30, achieve complete cleaning of the water outlet of the faucet assembly 30, reduce the bacterial count in the water used by the user, and achieve healthy drinking water.
[0042] like Figures 1 to 3 According to the embodiment of the present utility model, the water purification device 100 includes a first housing 10, a water outlet pipe 20, and a faucet assembly 30.
[0043] The first housing 10 is connected to the faucet assembly 30 via the water outlet pipe 20. The first housing 10 is equipped with a first disinfection module 11. The water outlet pipe 20 is equipped with a first water pump 21. The faucet assembly 30 is equipped with a first reversing valve 31. The inlet port of the first reversing valve 31 is connected to the outlet of the water outlet pipe 20. The first outlet port of the first reversing valve 31 is directly connected to the outlet of the faucet assembly 30.
[0044] It also includes a first return water pipe 40, and the second outlet port of the first reversing valve 31 is connected to the first housing 10 through the first return water pipe 40.
[0045] In summary, the water purification device 100 according to the present utility model embodiment directly connects the outlet of the faucet assembly 30 through the first reversing valve 31 to control the water flow to circulate between the first tank 10 and the outlet of the faucet assembly 30. The water flow can be disinfected and sterilized by the first disinfection module 11 when it flows through the first tank 10, so as to achieve complete cleaning from the first water tank 10 to the outlet of the faucet assembly 30, reduce the bacterial count in the water taken by the user, and achieve healthy drinking water.
[0046] Working principle of water purification equipment 100:
[0047] Driven by the first water pump 21, water can circulate between the first tank 10, the outlet pipe 20, the inlet of the faucet assembly 30, the outlet of the faucet assembly 30, and the first reversing valve 31. When the water flows through the first tank 10, the first disinfection module 11 can sterilize and disinfect the water. In this way, the problem of bacterial growth in the water purification equipment 100 caused by water in the outlet pipe 20 and the faucet assembly 30 can be solved. After disinfection, the water flow path from the first tank 10 to the faucet assembly 30 is clean and the bacterial count is greatly reduced, realizing healthy drinking water for users.
[0048] like Figure 1 and Figure 3 In some embodiments of this utility model, the water purification device 100 further includes an inlet pipe 50 and a second return pipe 60. The inlet pipe 50 is sequentially equipped with a second water pump 51 and an RO filter element 52 along the water flow direction, and the outlet of the inlet pipe 50 is connected to the first housing 10. The second return pipe 60 is equipped with a first control valve 61, the outlet of the second return pipe 60 is connected to the inlet of the second water pump 51, and the inlet of the second return pipe 60 is connected to the first housing 10. In this way, the inlet pipe 50 can be cleaned, the bacterial count in the user's drinking water can be reduced, and healthy drinking water can be achieved.
[0049] It is understandable that water remaining in the inlet pipe 50 can breed bacteria, resulting in a high bacterial count in the effluent from the water purifier 100. Therefore, the first control valve 61 can control the water flow to circulate between the first tank 10, the second return pipe 60, and the inlet pipe 50. Specifically, the water flows out of the first tank 10 and sequentially through the second return pipe, the second water pump 51, and the RO filter 52 before returning to the first tank 10. While the water flows through the first tank 10, the first disinfection module 11 can sterilize and disinfect the water. In this way, the problem of bacterial growth in the water purifier 100 caused by water remaining in the inlet pipe 50 can be solved. Furthermore, the water circulation between the first return pipe and the first tank 10 is driven by the first water pump 21, and the water circulation between the second return pipe and the first tank 10 is driven by the second water pump 51. The two water circulation loops can be cleaned separately without interfering with each other.
[0050] It needs to be explained that the RO filter element 52, Reverse Osmosis, is a reverse osmosis membrane filter element. It is pressurized by the second water pump 51, which forces water molecules to pass through the RO membrane, while heavy metals (lead, arsenic), bacteria, viruses, scale (calcium and magnesium ions), etc. are intercepted, realizing the filtration of the incoming water of the water purification equipment 100, improving the cleanliness of drinking water and meeting the needs of users.
[0051] like Figure 1 and Figure 2In some embodiments of this utility model, the water purification device 100 further includes a high-temperature pipeline 70 and a second reversing valve 73. A second housing 71 and a third water pump 72 are sequentially arranged along the water flow direction on the high-temperature pipeline 70, and the outlet of the high-temperature pipeline 70 is connected to the inlet of the faucet assembly 30. The inlet port and the first outlet port of the second reversing valve 73 are located on the first return water pipeline 40, and the second outlet port of the second reversing valve 73 is connected to the inlet of the high-temperature pipeline 70. In this way, high-temperature sterilization of the faucet assembly 30 can be achieved, and combined with the first disinfection module 11, it can effectively inhibit the growth and reproduction of bacteria in the faucet assembly 30.
[0052] It is understandable that water retention in the faucet assembly 30 can breed bacteria, resulting in a high bacterial count in the water output from the water purification device 100. Therefore, the first control valve 61 can be used to control the water flow to circulate between the faucet assembly 30 and the high-temperature pipe 70. Specifically, the water flows out from the second housing 71 and flows sequentially through the third water pump 72, the faucet assembly 30, and the second reversing valve 73 before returning to the second housing 71. During this process, the high-temperature pipe 70 can heat the water flow to achieve high-temperature sterilization, thereby inhibiting bacterial growth in the water purification device 100. Furthermore, the high-temperature sterilization effect of the high-temperature pipe 70 can be combined with the disinfection and sterilization of the water outlet pipe 20 to greatly improve the sterilization effect of the water purification device 100.
[0053] It should be noted that, in conjunction with the foregoing, the first chamber 10 can be used to store room temperature water, and the second chamber 71 can be used to store high temperature water. Thus, when the user needs room temperature water, the first chamber 10 can be connected to the faucet assembly 30 to enable the water purifier 100 to dispense room temperature water; when the user needs hot water, the second chamber 71 can be connected to the faucet assembly 30 to enable the water purifier 100 to dispense hot water.
[0054] The high-temperature pipeline 70 can be heated in various ways. In the first example, the high-temperature pipeline 70 can be constructed as a heating pipe. When water flows through the high-temperature pipeline 70, the high-temperature pipeline 70 can heat the water flow to achieve high-temperature sterilization. In the second example, an instant heating module 32 can be installed on the high-temperature pipeline 70. When water flows through the high-temperature pipeline 70, the instant heating module 32 can heat the water flow to achieve high-temperature sterilization.
[0055] like Figure 1 and Figure 2 According to the aforementioned second example, the water purification device 100 also includes an instant heating module 32, which is installed inside the faucet assembly 30. The outlet of the instant heating module 32 is connected to the inlet port of the first reversing valve 31, and the inlet of the instant heating module 32 is connected to the outlet of the third water pump 72. In this way, the growth and reproduction of bacteria in the faucet assembly 30 can be effectively inhibited, and the water circuit structure can be simplified, thereby improving the heating and sterilization effect.
[0056] Based on the foregoing, it can be understood that the water flow can circulate between the second housing 71, the third water pump 72, the faucet assembly 30, and the second reversing valve 73. During this process, the instant heating module 32 can heat the water flow in the high-temperature pipeline 70, thereby achieving high-temperature sterilization of the water flow and inhibiting the growth of bacteria in the water purification equipment 100. Furthermore, this embodiment of the present invention mainly sterilizes the faucet assembly 30. Therefore, the instant heating module 32 can be set inside the faucet assembly 30, which can simplify the water circuit structure and improve the space utilization of the water purification equipment 100.
[0057] like Figures 1 to 3 In some embodiments of this utility model, the water purification device 100 further includes a water outlet pipe 20, on which a first activated carbon filter element 81 is provided; thus, the water outlet can be purified a second time through the first activated carbon filter element 81, thereby improving the taste of drinking water.
[0058] Understandably, the first activated carbon filter element 81 has multiple nano-sized micropores; when water flows through the first activated carbon filter element 81, organic matter, residual chlorine, and odor molecules are adsorbed onto the pore walls by van der Waals forces, thereby further purifying the water quality and improving the taste of drinking water.
[0059] like Figure 1 and Figure 2 In some embodiments of this utility model, the water purification device 100 further includes a second disinfection module 22, which is disposed on the water outlet side of the first activated carbon filter element 81; in this way, the sterilization efficiency can be further improved, and healthy drinking water can be achieved for users.
[0060] Specifically, when water flows through the first activated carbon filter element 81, some unsterilized bacteria and other microorganisms carried in the water flow adhere to the first activated carbon filter element 81. When the first housing 10 is connected to the faucet assembly 30, the water flow in the first housing 10 can flow to the faucet assembly 30 for water outlet. In this process, the bacteria and other microorganisms on the first activated carbon filter element 81 are carried out, resulting in a high bacterial count in the water outlet of the water purification device 100. Therefore, a second disinfection module 22 can be provided on the water outlet side of the first activated carbon filter element 81. In this way, whether the water flow from the first housing 10 directly passes through the faucet assembly 30 for water outlet or returns to the first housing 10, the water flow can be disinfected a second time through the second disinfection module 22, improving the sterilization efficiency of the water purification device 100 and achieving healthy drinking water for users.
[0061] In some embodiments of this utility model, the first disinfection module 11 is a UV disinfection module; it can be understood that a UV disinfection module is provided in the first housing 10, which sterilizes and disinfects the water flow by ultraviolet light. The UV disinfection module has a fast sterilization effect, low maintenance cost, and can facilitate the water purification equipment 100 to provide users with clean and hygienic drinking water.
[0062] In some other embodiments of this utility model, the second disinfection module 22 is a UV disinfection module; it can be understood that a UV disinfection module is provided on the water outlet pipe 20, which sterilizes and disinfects the water flow by ultraviolet light. The UV disinfection module has a fast sterilization effect and low maintenance cost, which makes it easy for the water purification equipment 100 to provide users with clean and hygienic drinking water.
[0063] like Figure 1 In some embodiments of this utility model, the water purification device 100 further includes a raw water pipeline 90, which is connected to the inlet of the inlet water pipeline 50. A second activated carbon filter element 82 is provided on the raw water pipeline 90. The second activated carbon filter element 82 is combined with the first activated carbon filter element 81 to form a composite filter element. This arrangement can reduce the burden of water flow filtration, improve the filtration effect of water flow, and integrate the two activated carbon filter elements together, simplifying the filter element structure and improving the space utilization of the water purification device 100.
[0064] For example, the raw water pipe 90 is connected to the water source and the inlet pipe 50 respectively. The inlet pipe 50 is connected to the first tank 10. The first tank 10 is connected to the faucet assembly 30 through the outlet pipe 20. Water can flow out from the water source and flow through the raw water pipe 90, the inlet pipe 50, the first tank 10, the outlet pipe 20 and the faucet assembly 30 in sequence to realize drinking water output. During this process, when the water flows through the raw water pipe 90, the second activated carbon filter element 82 can first filter the raw water of the water source to remove impurities in the raw water. When the water flows through the outlet pipe 20, the first activated carbon filter element 81 can secondly filter the water to further remove impurities in the water, greatly improving the quality of drinking water.
[0065] Alternatively, the first activated carbon filter element 81 and the second activated carbon filter element 82 can be combined together. Specifically, the water purification equipment 100 may also include a filter element assembly 80, which includes a filter element housing, a first activated carbon filter element 81, and a second activated carbon filter element 82. The first activated carbon filter element 81 and the second activated carbon filter element 82 can be disposed inside the filter element housing, thereby combining the first activated carbon filter element 81 and the second activated carbon filter element 82 together. In other words, by installing the filter element assembly 80 inside the water purification equipment 100, the first activated carbon filter element 81 and the second activated carbon filter element 82 can be respectively disposed on the raw water pipeline 90 and the outlet water pipeline 20, which facilitates installation and assembly and improves the space utilization rate of the water purification equipment 100.
[0066] like Figure 3 In some embodiments of this utility model, the water purification device 100 also includes a circulation pump 14, the inlet and outlet of which are connected to the first tank 10; thus, the water flow in the first tank 10 can be circulated through the circulation pump 14, achieving disinfection without dead angles.
[0067] It is understandable that the circulation pump 14 is connected to the first tank 10 to form a normal temperature water tank cleaning circuit. Under the driving action of the circulation pump 14, the water flows between the first tank 10 and the circulation pump 14. When the water flows through the first tank 10, the first disinfection module 11 can disinfect and sterilize the water. Since the water in the first water tank 10 is flowing rather than stagnant, the water that has not been effectively irradiated by ultraviolet light can also flow to the effective disinfection area of the first disinfection module 11, so that the water in the tank can be fully disinfected by the first disinfection module 11, and bacteria can be prevented from growing in the first tank 10.
[0068] In this embodiment, the circulating pump 14 is connected to the first tank 10 to form a normal temperature water tank cleaning circuit. The first tank 10, faucet assembly 30, outlet pipe 20, and first return pipe 40 are connected to form an outlet cleaning circuit. The first tank 10, second return pipe 60, and inlet pipe 50 are connected to form an inlet cleaning circuit. The second tank 71, third water pump 72, faucet assembly 30, first reversing valve 31, and second reversing valve 73 are connected to form a high temperature cleaning circuit. The four cleaning circuits can clean their respective parts independently without interfering with each other, ensuring the cleaning and sterilization effect and achieving comprehensive disinfection of the water purifier. Specifically, the process involves first cleaning the ambient temperature water tank circuit to prepare sterile water; then, rinsing the inlet water cleaning circuit with sterile water; next, restarting the ambient temperature water tank cleaning circuit to re-sterilize the water in the first water tank 10, ensuring the tank remains sterile; then, rinsing the outlet water cleaning circuit with sterile water and flushing the pipes inside the faucet assembly 30; finally, activating the instant heating module to heat the water in the second water tank 71 to boiling, and then circulating it to rinse the faucet assembly 30, achieving high-temperature disinfection of the faucet assembly 30. This process achieves comprehensive disinfection of the water purifier.
[0069] In addition, different cleaning circuits can be selectively activated based on the operating time to achieve disinfection around the clock. For example, the ambient temperature water tank cleaning circuit is activated every 15 minutes; the inlet water cleaning circuit is activated every 5 hours; the outlet water cleaning circuit is activated every 12 hours; and the high temperature cleaning circuit is activated every 24 hours.
[0070] like Figure 4 In some embodiments of this utility model, the water purification device 100 further includes a stirring paddle 12 and a motor 13. The stirring paddle 12 is disposed inside the first housing 10; the motor 13 is connected to the stirring paddle 12 in a transmission manner; thus, the water flow in the first housing 10 can be disturbed by the stirring paddle 12 and the motor 13 to achieve disinfection without dead angles.
[0071] It is understandable that the first chamber 10 can store room temperature water. When the water purification equipment 100 is not in use, bacteria will grow in the water at room temperature. Furthermore, the first disinfection module 11, especially the UV disinfection module, has disinfection dead zones and cannot effectively disinfect the water in the first chamber 10. Therefore, a stirring paddle 12 can be provided in the first chamber 10, and the stirring paddle 12 can be driven by a motor 13 to stir the water in the first chamber 10. This will disturb the water flow in the first chamber 10, allowing the water to flow fully through the disinfection range of the first disinfection module 11, thereby improving the sterilization effect of the first disinfection module 11 on the water in the first chamber 10 and achieving disinfection without dead zones.
[0072] like Figure 1 In some embodiments of this utility model, a third disinfection module is provided on the water outlet pipe 20. The third disinfection module is set on the water outlet pipe 20 and is set as a UV disinfection module.
[0073] The water purification equipment 100 also includes a first branch pipe 53 and a second control valve 54. The inlet of the first branch pipe 53 is connected to the outlet of the RO filter element 52, and the outlet of the first branch pipe 53 is connected to the inlet of the third disinfection module. The second control valve 54 is located in the first branch pipe 53. This configuration can ensure the quality of drinking water for users when drinking directly and improve the user's drinking experience.
[0074] Understandably, when a user needs direct drinking water, the water can flow from the water source to the raw water pipe 90, and then to the inlet pipe 50, where it is filtered by the RO filter element 52. The filtered wastewater can be discharged to the wastewater outlet, while the purified water can flow along the first branch pipe 53 to the third disinfection module under the action of the second control valve 54. Under the UV disinfection action of the third disinfection module, bacteria in the raw water are killed, and then high-quality direct drinking can be achieved through the faucet assembly 30, improving the user's drinking experience.
[0075] Furthermore, the raw water flowing to the faucet assembly 30 can be returned to the first tank 10 under the action of the first reversing valve 31, ensuring that the water entering the first tank 10 remains sterile. It should be understood that the first disinfection module 11 within the first tank 10 is timed to activate, primarily for self-cleaning and sterilization during internal circulation within the water purification equipment 100. When water filtered by the RO filter 52 enters the first tank 10 without disinfection, and the first disinfection module 11 is not activated for timed sterilization, the purified water discharged from the first tank may still contain bacteria, affecting the user's drinking experience. However, with the first branch pipe 53, the second control valve 54, and the third disinfection module in this embodiment, even when direct drinking is not required, replenishing the first tank 10 with water via the combination of the first branch pipe 53 and the faucet assembly 30 ensures that the water in the first tank 10 is sterile, improving the cleanliness of the drinking water.
[0076] Furthermore, it should be understood that in some specific examples, the third disinfection module can be set as the second disinfection module 22 in the aforementioned embodiment. That is, the first water tank 10 water replenishment and the outlet pipe cleaning share a single disinfection module, simplifying the water circuit structure and reducing costs.
[0077] In some other embodiments of this utility model, a fourth disinfection module is provided on the water inlet pipe 50. The fourth disinfection module is connected to the water outlet of the RO filter 52 and is set as a UV disinfection module. In this way, the water inlet pipe 50 can disinfect the incoming water through the fourth disinfection module, ensuring that the water added to the first water tank 10 is sterile water. The first water tank 10 can output sterile water at any time, improving the user's drinking experience.
