Specific implementation mode

[0026] The first embodiment is specifically as Figures 1-6 shown in the figure.

[0027] As Figures 1-6 shown, a cold and hot water universal faucet shunt type multi-stage water purification device includes a cold water pipe 11 and a hot water pipe 12 located in a valve body 1. The water flows in the cold water pipe 11 and the hot water pipe 12 are mixed in a connecting pipe 8 for users to use, and a control valve core 7 is provided at the confluence of the three. A branch pipe opening is horizontally opened on the cold water pipe 11, and a cold water diversion pipe 13 is hermetically connected to the branch pipe opening. A flow control valve 2 is installed on the cold water diversion pipe 13. Through the flow control valve 2, users can adjust adaptively according to the demand of the water output. In this embodiment, the flow control valve 2 includes a control valve housing 21 provided on the outer side of the cold water diversion pipe 13, and the adjustment switch of the flow control valve 2 is exposed on the outer surface of the control valve housing 21. The adjustment switch has a total of three grades I, II, and III, corresponding to different water flow rates respectively.

[0028] The water outlet end of the cold water diversion pipe 13 is successively connected with a primary water purification device 3, a secondary water purification device 4, a water quality monitor 5 and a water outlet pipe 6 along the water flow direction. The primary water purification device 3 includes a cuboid-shaped first housing 31, and the extending direction of the first housing 31 is perpendicular to the extending direction of the cold water diversion pipe 13. One end of the cold water diversion pipe 13 far from the valve body extends until it reaches the side surface of the first housing 31 and is communicated with it. It should be noted that in this embodiment, one end of the first housing 31 facing the adjustment switch is open, and the square opening is closed to form a circular opening. A connecting convex ring 311 is welded on the circular opening, and the inner diameter of the connecting convex ring 311 is the same as the diameter of the circular opening. A first cover plate 33 is threadedly connected to the outer side surface of the connecting convex ring 311. A circular first installation groove 34 is opened at the center position of the inner plate surface of the first cover plate 33, and a cylindrical first filter element 32 is detachably connected in the first installation groove 34. In this embodiment, the first installation groove 34 is threadedly connected with the first filter element 32. The end surface of the first filter element 32 far from the first cover plate 33 is in contact with the bottom surface of the first housing 31, and there are intervals between the periphery of the first filter element 32 and the inner wall of the first housing 31.

[0029] A first flow channel 321 with single-sided water outlet is opened at the center position inside the first filter element 32, and a water outlet hole corresponding to the first flow channel 321 is opened on the bottom surface of the first housing 31. The water body enters the cavity inside the first housing 31 along the cold water diversion pipe 13, enters from the outer surface of the first filter element 32 and converges in the first flow channel 321 in the middle of the first filter element 32, thus completing the primary purification;

[0030] The secondary water purification device 4 is arranged above the primary water purification device 3. The secondary water purification device 4 includes a cylindrical second housing 41 extending in the vertical direction. Similarly, the upper end of the second housing 4 is open, and a second cover plate 43 is threadedly connected to the opening. A circular second installation groove 44 is opened at the center position of the inner plate surface of the second cover plate 43, and a cylindrical second filter element 42 is detachably connected in the second installation groove 44. In this embodiment, the second installation groove 44 is threadedly connected with the second filter element 42. The second filter element 42 extends in the vertical direction until it is in contact with the bottom surface of the second housing 41, and there are intervals between the periphery of the second filter element 42 and the inner wall of the second housing 41. A second flow channel 421 with single-sided water outlet is opened at the center position inside the second filter element 42, and a water outlet hole corresponding to the second flow channel 421 is opened on the bottom surface of the second housing 41.

[0031] An inlet hole is arranged on the bottom surface of the second housing 41, and the inlet hole is located outside the second filter element 42. The water outlet hole on the bottom surface of the first housing 31 is communicated with the inlet hole on the bottom surface of the second housing 41. The water body after primary purification enters the cavity inside the second housing 41 along the pipeline, enters from the outer surface of the second filter element 42 and converges in the second flow channel 421 in the middle of the second filter element 42, thus completing the secondary purification.

[0032] On one side of the second housing 41 away from the valve body 1, a water quality monitor 5 (model number WQMA - 4210) is welded. The water inlet of the water quality monitor 5 is connected to the water outlet of the second housing 41 through a pipeline. The water body after secondary filtration flows into the water quality monitor 5 through the pipeline. The water body after two - stage filtration is monitored by the water quality monitor 5, and the following parameters can be measured: total hardness, alkalinity, conductivity, PH, turbidity, etc. The water quality monitor 5 evaluates the water quality of the water body based on the above - mentioned parameters (the specific evaluation criteria can refer to the national mandatory standard GB34914 - 2021). The water quality monitor 5 includes a display screen arranged on the machine side, and the display screen can display the evaluation results (Class I, Class II, Class III) in real time. Users can replace the first filter element 32, the second filter element 42 separately or replace both of them at the same time according to the display results.

[0033] A water outlet pipe 6 is rotatably connected at the water outlet of the water quality monitor 5. After the water outlet pipe 6 is bent twice, the water outlet direction is vertically downward. The formed open space can surround the upper part of the secondary water purification device 4. The water outlet pipe 6 rotates 360°. When there is no water demand, the water outlet pipe 6 can be rotated to store it, achieving the purpose of saving the kitchen counter space.

[0034] During use, first, turn on the switch of the water outlet pipe 6. The water body enters the primary water purification device 3 through the cold water diversion pipeline 13. The primary water purification device 3 purifies the water body at the primary level. Then, the purified water body enters the secondary water purification device 4 along the pipeline, and the secondary water purification device 4 purifies the water body at the secondary level. Finally, the water body enters the water quality monitor 5 after two - stage purification and flows out from the water outlet pipe 6. By performing two - stage hierarchical purification on the water body, the water quality can be effectively improved. And by setting up the water quality monitor, the water quality situation is monitored in real time. According to the monitoring results, the user is reminded to replace the filter element in time to ensure healthy water quality. In addition, one end of the housing is open and threadedly connected with a cover plate. The filter element is threadedly connected to the inner plate surface of the cover plate. The filter element can be replaced by taking out the cover plate. The structure is simple and the operation is convenient, significantly improving the replacement efficiency of the filter element, thus effectively ensuring the user experience.

[0035] Finally, it should be noted that the above - mentioned preferred embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail through the above - mentioned preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
