[0032] Please refer to Figure 1 and Figure 3 The water outlet pipe 103 is in a "U"-shaped structure. The regulating pipe 3 is movably connected to the water outlet pipe 103 through the movable hole 301. The regulating pipe 3 and the water outlet pipe 103 can be telescopically adjusted through the movable hole 301. A threaded hole matching the limit bolt 302 is provided at the top of the outer side of the regulating pipe 3. The limit bolt 302 is threadedly connected to the regulating pipe 3 through the threaded hole, so that the limit bolt 302 and the regulating pipe 3 can be adjusted.

[0033] Working principle: Before use, the utility model is installed between the tap water pipe and the faucet through the installation head 104. When in use, turn on the power, manually turn the adjustment knob 201 to set the water temperature, and the water temperature is displayed on the display screen 203. The control switch 202 controls the power on and off of the two sets of electric valves 204. Turn on the control switch 202, open the two sets of electric valves 204, and the tap water flows into the cold water pipe 101 and the hot water pipe 102 respectively through the water inlet pipe 1. The tap water in the hot water pipe 102 will be heated to 99 degrees through the electric heating pipe. The water in the hot water pipe 102 and the cold water pipe 101 will be mixed in the water outlet pipe 103, and the mixed water can be regulated by the temperature sensor 206. The temperature of the tap water is detected. When the water temperature is higher than the set temperature, the electric valve 204 at the hot water pipe 102 will be controlled to reduce the flow of the hot water pipe 102 until it drops to the preset temperature. When the water temperature is lower than the set temperature, the electric valve 204 at the cold water pipe 101 will be controlled to reduce the flow of the cold water pipe 101 until it reaches the preset temperature. This makes the control of the water outlet temperature more precise and improves the practicality of the heating faucet. The movable hole 301 can be used to adjust the adjustment tube 3 and the water outlet pipe 103 to adjust the water outlet position, and the limit bolt 302 can be used to limit the adjustment tube 3 and the water outlet pipe 103, so that the faucet can be used better.
