[0062] Specifically, the faucet 5 is equipped with a corresponding control (not shown in the figure), which can be a touch screen button, a mechanical button, or a knob button, an inductive switch, etc., which is not limited here; the control allows the user to trigger the operation to adjust whether the faucet releases tap water or pure water. Specifically, when tap water is needed, the water inlet valve 36 is closed, and the first proportional valve 41 and the second proportional valve 42 are opened; when pure water is needed, the water inlet valve 36 is opened, and the first proportional valve 41 and the second proportional valve 42 are closed.

Optionally, the pure water outlet valve 35 and the tap water outlet valve 49 can also be electric valves; here is not limited; the pure water outlet valve 35 and the tap water outlet valve 49 can be the same type of valve, or different types of valves.

[0065] In a specific embodiment, the water inlet end of the purified water channel 3, the water inlet end of the tap water channel 4, and the cold water pipe 1 are further provided with a softening device 6; specifically, the softening device 6 is used to soften the water quality, remove the hardness components such as calcium and magnesium ions in the water, reduce the formation of scale, prolong the service life of the water pipe and equipment, and improve the taste of the water.

[0066] Optionally, the softening device can be a resin. Based on the characteristics that the resin has good adsorption performance, the hardness ions in the water are removed by ion exchange. Optionally, the softening device can also be a magnetization softener, which uses a magnetic field to change the electron distribution in water molecules, thereby reducing the ability of calcium and magnesium ions to form scale. Optionally, the softening device can also be a reverse osmosis system, which removes hardness ions in water through a semi-permeable membrane.

[0067] In the utility model, by connecting the tap water channel and the purified water channel on one faucet, it is realized that only one faucet needs to be installed to discharge tap water or purified water, without using two faucets. At the same time, in the water channel structure, the tap water channel does not pass through the filter of the purified water channel, avoiding the problem that the tap water channel and the purified water channel share a filter in the prior art, so that high-temperature water passes through the filter, damaging the filtering performance of the filter core.

[0068] Please refer to Figure 3 , Figure 3 A structure diagram of a tap water channel is shown; in the embodiment of the utility model, the tap water channel 4 includes: a first proportional valve 41 and a second proportional valve 42; the water inlet end of the tap water channel 4 is connected with the cold water pipe 1 through the first proportional valve 41 and connected with the hot water pipe through the second proportional valve 42; the first proportional valve 41 and the second proportional valve 42 are controlled by electric signals, and the first proportional valve 41 and the second proportional valve 42 cooperatively adjust the water temperature of tap water in the tap water channel 4. Based on the preset water temperature of the user or based on the expected water temperature input by the user through the control, a control signal is generated to the control system (not shown in the figure). After the control system receives the control signal, according to the selection of the user, the valve opening angle of the first proportional valve 41 and the second proportional valve 42 is adjusted, and through the cooperative control of the first proportional valve 41 and the second proportional valve 42, the water temperature of tap water in the tap water channel reaches the temperature requirement set by the user.

[0069] Here, the first proportional valve 41 and the second proportional valve 42 are electrically controlled valves, and the valve opening angle of the valve is accurately adjusted according to the size of the electric signal, so as to control the flow of cold and hot water or hot coolant, so as to accurately control the water temperature. In this embodiment, the valve opening angle of the first proportional valve and the second proportional valve is controlled by the electric signal, so as to control the flow of cold and hot water, so as to accurately control the temperature of tap water, meet the temperature requirement of different water use occasions; at the same time, the system is more automatic through the electric signal control, without manual adjustment of the valve, improve the convenience of use and the accuracy of temperature control, improve the user experience.

[0070] The tap water channel 4 further comprises a mixing chamber 43 and a temperature detector 44; one end of the mixing chamber 43 is connected with the first proportional valve 41 and the second proportional valve 42 respectively, for mixing and accommodating the tap water adjusted by the first proportional valve 41 and the second proportional valve 42; the temperature detector 44 is used for detecting the temperature of the tap water in the tap water channel 4, and generating the electric signal based on the temperature of the tap water.

[0071] Specifically, the temperature detector 44 is a temperature sensor; optionally, the temperature sensor can be a thermocouple sensor, can be a thermal resistance, can be a semiconductor temperature sensor or a capacitive temperature sensor, etc. In this embodiment, the temperature detector 44 can be any device capable of detecting the temperature of the tap water flow in the tap water channel; the temperature detector 44 converts the temperature information into an electric signal output after detecting the temperature of the tap water, so as to control the valve opening angle of the first proportional valve 41 and the second proportional valve 42, and adjust the flow of cold water and hot water in the tap water channel 4.

[0072] In this way, the temperature of the tap water is accurately controlled by the electric signal control and the temperature detector, the energy waste caused by the too high or too low water temperature is avoided, the wear of the equipment is reduced, the service life of the equipment is prolonged, and the energy use efficiency is improved.

[0073] The mixing chamber 43 and the temperature detector 44 are further provided with a disinfection device 45; the disinfection device 45 comprises a flow meter 451 and a heating body 452; one end of the flow meter 451 is connected with the other end of the mixing chamber 43, the other end of the flow meter 451 is connected with the heating body 452, for detecting whether there is water flow in the tap water channel 4; the heating body 452 is connected with the temperature detector 44, for heating the tap water to disinfect the tap water channel 4 at high temperature in the case of receiving a disinfection signal.

[0074] Specifically, the flow meter is an instrument for measuring the flow of tap water in the tap water pipeline or the flow of equipment. Optionally, the flow meter can be a differential pressure flow meter, which calculates the flow by measuring the pressure difference generated when the fluid flows through the pipeline; optionally, the flow meter can also be a mass flow meter, which directly measures the mass flow of the fluid through the pipeline, etc.; here is not limited.

[0075] Specifically, in the case of receiving a disinfection signal, the flow meter 451 monitors the water flow state in the tap water pipeline 4 in real time. If the water flow is detected, the flow meter 451 will feed back a signal to the control system to trigger the start of the disinfection device 45 and execute the high-temperature disinfection program. If no water flow is detected, the flow meter 451 will immediately alarm the control system to prevent the disinfection device 45 from running in the absence of water flow, thereby avoiding unnecessary damage to the water pipeline.

[0076] In this way, the bacteria and pathogens in tap water are effectively eliminated by high-temperature disinfection, improving water quality safety; at the same time, the system can adjust the disinfection temperature and duration according to actual needs to adapt to different disinfection requirements.

[0077] The water pipeline structure further comprises an air inlet valve 47 and an air inlet 46; the tap water pipeline 4 further comprises a bubbling device 48; the air inlet valve 47 is connected between the bubbling device 48 and the air inlet 46, for controlling the inflow of air into the bubbling device 48; the bubbling device 48 is connected between the temperature detector 44 and the water inlet 51 of the faucet 5, for mixing air flowing from the air inlet 46 with tap water to generate bubbled water when the air inlet valve 47 is opened.

[0078] Specifically, the tap water pipeline 4 further comprises a pressure reducing valve (not shown in the figure), and the bubbling device 48 further comprises a fluidic device 481 and a bubbler 482.

[0079] The pressure reducing valve is connected between the temperature detector 44 and the fluidic device 481, for ensuring that the water flow is controlled within a safe range before reaching the fluidic device 481, to prevent damage to the fluidic device or other downstream equipment caused by excessive pressure.

[0080] The fluidic device 481 is connected with the air inlet valve 47 and the bubbler 482, respectively; specifically, the fluidic device 481 is a fluid power device that generates negative pressure through high-speed jet flow, for sucking and mixing air with tap water.

[0081] The bubbler 482 is arranged between the tap water outlet valve 49 and the fluidic device 481; the bubbler is used to mix air with tap water to generate bubbled water.

[0082] Specifically, when the foaming water needs to be generated, the control system sends a signal to the air inlet valve 47 to open it. The air inlet 46 starts to introduce air, and the negative pressure generated by the jet 481 sucks the air and tap water into the foaming device 482. The foaming device 48 mixes the air with the tap water to generate the foaming water.

[0083] In this way, the foaming water is generated based on the user's demand, the flushing efficiency is improved by the foaming water, and thus the water consumption is reduced; meanwhile, the generated foaming water is mixed with air, the water quality is improved to a certain extent, and the odor and bacteria are reduced.

[0084] Please refer to Figure 4 , Figure 4 A structure diagram of a tap water waterway is shown; in the embodiment of the utility model, the water purification waterway 3 still includes: first water quality detection device 32 and second water quality detection device 33;The first water quality detection device 32 is connected between the filter device 31 and the cold water pipe 1, and is used to detect the first water quality index of raw water in the water purification waterway 3 before filtration;The second water quality detection device 33 is connected between the filter device 31 and the water inlet 51 of the faucet 5, and is used to detect the second water quality index of purified water in the water purification waterway 3 after filtration.

[0085] Specifically, the first water quality detection device 32 and the second water quality detection device 33 are total dissolved solids (Tota lDi sso l ved So l i ds, TDS) probes;The first water quality index is a first TDS index, and the second water quality index is a second TDS index.

[0086] In this way, by detecting the TDS indexes before and after filtration, the filter core life of the first filter core and the second filter core can be determined based on the detected water quality indexes before and after filtration on the basis of ensuring the safety of the purified water quality, so that the filter core can be replaced in time in the case of reduced filtration performance.

[0087] The filter device 31 includes: a first filter core 311 and a second filter core 312;The first end of the first filter core 311 is connected with the first water quality detection device 32;The second end of the first filter core 311 is connected with the second filter core 312, and respectively constitutes a first filtration waterway 301 and a second filtration waterway 302;The first filtration waterway 301 is used to transmit the raw water filtered by the first filter core 311 to the second filter core 312 for second filtration;The second filtration waterway 302 is used to transmit the raw water filtered by the second filter core 312 to the first filter core 311 for third filtration;The third end of the first filter core 311 is connected with the second water quality detection device 33, and is used to transmit the purified water generated after the third filtration to the second water quality detection device 33.

[0088] Specifically, the filter pore size of the first filter element 311 is larger than that of the second filter element 312. Optionally, the first filter element 311 can be an activated carbon filter element, a ceramic filter element, a polypropylene cotton filter element, etc.; and optionally, the second filter element 312 can be an ultrafiltration filter element, a nanofiltration filter element, a reverse osmosis filter element, etc.

[0089] The large filter pore size of the first filter element effectively removes larger particles and impurities, reduces the working load of the second filter element, and prolongs the service life of the filter element. The small filter pore size of the second filter element further filters out the tiny particles and dissolved substances that the first filter element fails to capture, providing a higher standard of filtration effect. By setting the first filter element and the second filter element, the effect of graded filtration is achieved, improving the efficiency of water quality treatment.

[0090] Specifically, the raw water in the purified water channel 3 is first detected by the first water quality detection device 32 to obtain the first water quality index, so as to evaluate the initial water quality. After the larger impurities are filtered out by the first filter element 311, the raw water reaches the second filter element 312 through the first filtration water channel 301 for secondary filtration to filter out tiny particles and dissolved substances. The twice-filtered raw water reaches the first filter element 311 again through the second filtration water channel 302 for tertiary filtration to generate purified water; and the second water quality detection device 33 detects the second water quality index of the purified water.

[0091] In this way, through three-stage filtration and twice water quality detection, the water quality in the purified water channel 3 is ensured to reach the safety standard.

[0092] The filtration device 31 further comprises a booster pump 34; the booster pump 34 is arranged in the first filtration water channel 301 between the first filter element 311 and the second filter element 312; and the booster pump 34 is configured to flush the second filter element 312 when the difference between the second water quality index and the first water quality index reaches a preset value.

[0093] Specifically, the preset value can be a system default value or can be customized by the user. When the difference between the second water quality index and the first water quality index reaches the preset value, it indicates that the filtration performance of the current second filter element 312 is reduced, and the second filter element 312 can be flushed by the booster pump 34 to ensure the cleanliness of the filter element, prevent the filter element from being clogged, and improve the filtration performance of the filter element. At the same time, the frequency of replacing the filter element can be reduced, and the maintenance cost can be reduced.

[0094] In a specific embodiment, a pressure gauge 37 is further arranged between the booster pump 34 and the second filter element 312; the pressure gauge can detect the water flow pressure of the booster pump 34 flushing the second filter element 312, so as to ensure that no excessive pressure is caused when flushing the second filter element 312, thereby avoiding damage to the filter element or other system components.

[0095] In a specific embodiment, as shown in Figure 2 The waterway structure further comprises a wastewater waterway 6; the wastewater waterway comprises a wastewater proportional valve 61, a wastewater on-off valve 62, a drain valve 63 and a wastewater outlet 64.

[0096] The wastewater proportional valve 61 is connected with the second filter element 312, and the wastewater on-off valve 62 is arranged between the wastewater proportional valve 61 and the wastewater outlet 64. In the case of flushing the second filter element 312 by the booster pump 34, the wastewater on-off valve 62 is opened, and the flushed wastewater is transmitted to the wastewater outlet 64 through the wastewater proportional valve 61 and the wastewater on-off valve 62 and discharged.
