[0032] The utility model provides a water circuit system of a water purifier. In order to make the purpose, technical scheme and effect of the utility model clearer and more specific, the utility model is further described in detail below with reference to the accompanying drawings and examples.

[0033] In the description of the present invention, it should be understood that the terms "up, down, left, right, etc." indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and should not be understood as limiting the present invention; in addition, the terms "installation" and "connection" should be understood in a broad sense, and those skilled in the art can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0034] See also Figure 1 The utility model provides a water channel system of a water purifier, which realizes the functions of multi-stage filtration of raw water, preparation of pure water and hydrogen-rich water, and heating of output water by comprehensively applying multiple water channel channels and functional components.

[0035] In the filtration water circuit, the raw water first passes through the PCB filter element 1 for preliminary filtration, and then the RO filter element 2 further removes fine impurities and dissolved substances to ensure the purity of the water quality. At the same time, the filtration water circuit is also equipped with a pure water valve 3 and a pure water check valve 4 to ensure that the water flows in a single direction to the hydrogen-rich water tank 5 to avoid the backflow of filtered water.

[0036] The hydrogen-rich water circuit includes a hydrogen-rich water tank 5, an electrolyzer 6, a hydrogen mixing pump 7 and a hydrogen-rich valve 8 connected in sequence. The hydrogen-rich water tank 5 collects filtered water and then transports it to the electrolyzer 6 to produce hydrogen-rich water, wherein the user needs to manually add water to the hydrogen-rich water tank 5 when using it. This process increases the hydrogen concentration in the water. In order to ensure the oxygen content of the electrolyzed water, an aeration head 11, a wastewater proportional valve 12 and a hydrogen-rich one-way valve 13 and other components are added to the system. At the same time, a TDS probe 14 is set between the electrolyzer 6 and the hydrogen-rich water tank 5 to monitor the water quality in real time.

[0037] In another feasible embodiment, the water system of the water purifier has a larger flow rate than the traditional water system, and adopts an overflow type hydrogen production method. Compared with the traditional water purifier water system, there is no need for a hydrogen-rich water tank 5 to store water.

[0038] In order to facilitate users to obtain hot water or warm water as needed, a heating water circuit is also included. The heating water circuit is equipped with a flow meter 9 and a thick film heating tube 10. The rated power of the thick film heating tube 10 is 2000W, which can accurately control the amount of heated water, save energy and protect the equipment from the risk of dry burning.

[0039] In addition, a liquid level detector is installed in the hydrogen-rich water tank 5 to automatically monitor the water level to prevent overflow or water shortage. The wastewater solenoid valve 15 on the wastewater waterway controls the wastewater discharge to maintain the cleanliness and efficient operation of the system. In detail, there are two wastewater solenoid valves 15, and the two wastewater solenoid valves 15 can cooperate to adjust the different wastewater discharge volumes in the current water outlet mode.

[0040] The system also adds a water inlet solenoid valve 16 and a booster pump 17 between the PCB filter element 1 and the RO filter element 2. The two work together to increase the water pressure and ensure that the water flows smoothly through the filter elements at all levels, thereby optimizing the entire purification process. In order to cope with possible pressure anomalies, the system also sets a pressure relief valve 18 between the hydrogen mixing pump 7 and the water inlet solenoid valve 16 and the booster pump 17 to protect the RO, avoid excessive pressure on the RO membrane, and ensure stable and safe operation of the system.

[0041] In summary, the water system of the water purifier of the utility model can significantly improve the efficiency and convenience of drinking water treatment by integrating filtering, purification, hydrogen enrichment and heating functions. Multi-stage filtration uses PCB and RO filter element 2 to continuously remove impurities, ensuring the purity of water quality. The built-in electrolyzer 6 directly produces hydrogen-rich water from the hydrogen-rich water tank 5. The large-flow water system takes into account the flow-through hydrogen production, and no additional storage of drinking water is required. In addition, the flexible water configuration allows users to easily switch between pure water and hydrogen-rich water supply according to their needs, and the heating water circuit meets the needs of drinking water at different temperatures. Overall, it improves the user experience and demonstrates a high degree of functionality and market appeal. Therefore, the utility model effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.

[0042] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
