Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

FIG. 1 is a schematic structural diagram of a faucet provided by an embodiment of the present invention. As shown in Figure 1, the faucet includes: a first water inlet pipe 1, a second water inlet pipe 2, a mixing chamber 3, a water outlet pipe 4, a water temperature measuring device 5 and an LED water temperature warning device 6; The water inlet pipe 2 and the water outlet pipe 4 are respectively connected to the mixing chamber 3; the water temperature measuring device 5 is arranged on the inner wall of the mixing chamber 3; the LED water temperature early warning device 6 is electrically connected to the water temperature measuring device 5. The above-mentioned electrical connection relationship is hidden inside the faucet structure, so it is not shown in FIG. 1 .

When the faucet needs to discharge water, hot water can enter the mixing chamber 3 through the first water inlet pipe 1 , and cold water can enter the mixing chamber 3 through the second water inlet pipe 2 . The water temperature measuring device 5 in the mixing chamber 3 collects the mixed output water temperature of hot and cold water in real time, and sends the collected mixed output water temperature to the LED water temperature warning device 6 . The LED water temperature early warning device 6 displays early warning information according to the cold and hot output water temperature collected in real time.

Those skilled in the art can understand that when the faucet provided by the embodiment of the present invention is in use, hot water can also enter the mixing chamber 3 through the second water inlet pipe 2, and cold water can also enter the mixing chamber 3 through the first water inlet pipe 1.

In an embodiment of the present invention, the LED water temperature warning device 6 may include: red LED display lights, blue LED display lights and green LED display lights, so that different warning information can be represented by different colored LED display lights. For example, when people take a bath, the normal water temperature that the skin can touch is 35°C to 37°C. When the temperature of the hot and cold output water collected in real time by the water temperature measuring device 5 is lower than 35°C, it means that the current mixed output water temperature is too low and may cause frostbite. , at this time the blue LED display light is on; when the cold and hot output water temperature collected in real time by the water temperature measuring device 5 is higher than 37°C, it means that the current water temperature output by the faucet will cause burns, and the red LED display light is on at this time; When the cold and hot output water temperature collected in real time by the water temperature measuring device 5 is between 35° C. and 37° C., it means that the water output from the faucet can be safely used at present, and the green LED indicator light is on at this time. In this way, different early warning information is represented by different colors, and the early warning information conveyed is easier to identify, especially for the elderly and children with poor self-care ability.

In another embodiment of the present invention, the LED water temperature early warning device 6 may also include an LED display screen showing at least three colors of red, blue and green. Among them, when the LED display is red, it means the water temperature over-temperature warning information, when it is blue, it means the water temperature low temperature warning information, and when it is green, it means the water temperature is normal.

Those skilled in the art can understand that there are many ways for the LED water temperature early warning device 6 to display the early warning information. For example, the LED water temperature early warning device 6 can also directly display the number of the mixed output water temperature in real time. The present invention does not limit the manner in which the LED water temperature early warning device 6 displays early warning information.

FIG. 2 is a schematic structural diagram of a faucet provided by another embodiment of the present invention. As shown in Figure 2, different from the structure of the faucet shown in Figure 1, the faucet further includes: a first flow valve 7 and a second flow valve 8; At the interface, the second flow valve 8 is arranged at the interface between the second water inlet pipe 2 and the mixing chamber 3 . In this way, the flow of water introduced by the first water inlet pipe 1 and the second water inlet pipe 2 can be controlled respectively through the first flow valve 7 and the second flow valve 8, so as to control the mixed output water temperature. For example, when the first water inlet pipe 1 leads into hot water, the second water inlet pipe 2 leads into cold water, and the warning information given by the LED water temperature warning device 6 is that the mixed output water temperature is overheated; The flow of hot water in the chamber 3, or through the second flow valve 8 to increase the flow of cold water introduced into the mixing chamber 3.

In an embodiment of the present utility model, the first flow valve 7 is integrated with a first adjusting device 71 for adjusting the opening amount of the valve, and the second flow valve 8 is integrated with a second adjusting device 81 for adjusting the opening amount of the valve.

The valve controller 11 can uniformly control the valve openings of the first flow valve 7 and the second flow valve 8, and the flow of hot water/cold water introduced into the mixing chamber 3 can be automatically adjusted.

Specifically, the first temperature measuring device 9 sends the collected water temperature of the first water inlet pipe 1 to the valve controller 11, and the second temperature measuring device 10 sends the collected water temperature of the second water inlet pipe 1 to the valve controller. The controller 11; the valve controller 11 can calculate the water temperature required by the first water inlet pipe 1/second water inlet pipe 2 respectively when the preset mixed output water temperature is to be realized according to the imported water temperature of the first water inlet pipe 1/second water inlet pipe 2.

In an embodiment of the present invention, when the set mixed output water temperature is too high or too low, the set mixed output water temperature may not be realized. For example, when the first water inlet pipe 1 introduces hot water and the second water inlet pipe 2 introduces cold water, and the set mixed output water temperature is higher than that of the first water inlet pipe 1, or higher than that of the second water inlet pipe. 2 when the imported water temperature is still low; no matter how the valve controller 11 adjusts the imported flow rate of the first water inlet pipe 1/second water inlet pipe 2, the set mixed output water temperature cannot be achieved. At this time, the LED water temperature early warning device 6 can flash to show that the current temperature setting cannot be realized, and remind the user to reset the desired mixed output water temperature.

In an embodiment of the utility model, the valve controller 11 and the LED water temperature early warning device 6 can also be integrated into a temperature controller.
