[0035] The faucet body 1 is provided with a water channel support 3 and a water channel body 6 inside. The water channel body 6 is installed at the inner bottom of the faucet body 1. The water channel support 3 is installed on the water channel body 6. The detection component 7 is arranged on the water channel body 6.

[0042] In this embodiment, the display panel assembly 4 includes a single-chip microcomputer and a display screen. The single-chip microcomputer is arranged in the display screen. The input end of the single-chip microcomputer is electrically connected to the output end of the external power supply. The output ends of each TDS probe, each pressure sensor and the raw water temperature sensor 75 are respectively connected to the input end of the single-chip microcomputer.

The TDS probe and the temperature sensor probe will detect the total solid dissolved content and temperature in the water, and transmit the detected data to the single-chip microcomputer, and display the detected data through the display.

[0043] In this embodiment, the clean water control component 9 includes a clean water valve core 91, a clean water valve core pressure ring 92, a wear-resistant ring 93 and a clean water handle 94; the raw water control component 10 includes a raw water valve core 101, a raw water valve core pressure ring 102, a blocking ring 103 and a raw water handle 104.

The clean water pipe 81, the cold water pipe 82 and the hot water pipe 83 are respectively connected to the water channel body 6 through threaded connection, which is convenient for disassembly and assembly.

[0045] The purified water and raw water of the present invention have independent water paths respectively:

[0046] Purified water circuit: purified water pipe → water circuit main body → purified water TDS probe → purified water valve core → purified water pressure sensor → temperature sensor → sterilizer lamp → purified water outlet inner pipe → purified water outlet nozzle.

[0047] Raw water circuit: cold water pipe and hot water pipe → water circuit main body → temperature sensor → raw water valve core → raw water pressure sensor → raw water TDS probe → water circuit bracket → water outlet adapter → cold and hot water outlet elbow → cold and hot water outlet nozzle.

[0048] In this embodiment, the pressure sensor is installed at the water outlet end of the valve core. When the pressure sensor senses the water outlet pressure, the sensing signal can be sent to the single-chip microcomputer, and the sterilization lamp is controlled by the single-chip microcomputer to start working. At the same time, the TDS probe and temperature sensor can detect the total dissolved solids and temperature in the water, and display them through the display panel assembly.

[0049] In this embodiment, the TDS value is displayed accurately, and the change of water quality TDS can be monitored in real time according to the change of water temperature. At the same time, the purification degree of the water purifier filter element can be reflected in time, and the user can be reminded to replace the filter element in time to ensure the health of direct drinking water.

[0050] In this embodiment, a UVC-LED sterilizing lamp is used. The LED sterilizer needs a driver circuit board, which needs to occupy a certain space and can only be started with water. Otherwise, it is easy to burn out without water, so a device that senses water flow is needed. Traditional water flow switches or other sensors are large in size. Using a pressure sensor effectively solves this problem. Currently, no faucet does this. The sensor is small in size, precise in control, and easy to assemble. The sterilizing lamp has the advantages of small size, high efficiency, non-toxicity, low energy consumption, long life, safe voltage operation, and shock and drop resistance.

[0051] The water channels of the present invention are cleverly designed, mutually independent, and small in overall size. One faucet solves the use functions of two faucets, saving home decoration space, and the efficient sterilization ensures the health of direct drinking water.

[0052] In this embodiment, the pressure sensor is XGZP181, which is small and relatively accurate. The traditional water flow switch is large and takes up space, resulting in a large overall faucet, which is not conducive to the installation environment, so a pressure sensor is used to sense the water flow. The pressure sensor at the water purification end can also be replaced by Hall induction at the valve core handle, but it is not as accurate as the pressure sensor and is more troublesome to assemble, because the valve core handle generally requires two actions to open the valve core, so sensing the water flow through the action of the handle is not accurate.

[0053] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
