Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figures 1-11 A heating component for a faucet, the heating component includes an instant heating component 2 and a cold water pipe 1. The instant heating component 2 has a heating channel 4, one end of which is connected to a water source and the other end of which is connected to the hot water outlet of the faucet. The cold water pipe 1 has a cold water channel 3, one end of which is connected to a water source and the other end of which is connected to the cold water outlet of the faucet.

[0034] This device is equipped with an instant heating component 2 and a cold water pipe 1. One end of the heating channel 4 is connected to a water source, and the other end is connected to the hot water outlet of a faucet. The cold water pipe 1 has a cold water channel 3, one end of which is connected to a water source, and the other end is connected to the cold water outlet of a faucet. When hot water is needed, the hot water valve of the faucet is opened, and the tap water flows out after being heated through the heating channel 4. When cold water is needed, the cold water valve of the faucet is opened, and the tap water flows out directly through the cold water pipe 1. In this way, the flow rate of room temperature water is not limited by the water flow structure of the instant heating component 2, and room temperature water can be obtained quickly and heated water can be obtained conveniently.

[0035] The diameter of the cold water channel 3 in this device is larger than that of the heating channel 4, which ensures a larger outflow of room temperature water.

This device protects the electric heating element 9 through the metal shell 15, absorbs the heat generated by the electric heating element 9 through the metal shell 15, and cools the metal shell 15 and recovers heat through the water flowing through the return pipe 8, thus avoiding overheating of the instant heating component 2.

[0037] As an installation method, the heating component 2 includes a water inlet seat 6, which has a first flow channel 22, a second flow channel 23, a third flow channel 24, and a fourth flow channel 25. The first flow channel 22 and the fourth flow channel 25 are separated. The first flow channel 22 connects the water source and the second flow channel 23.

The second flow channel 23 has a first connecting part 29 arranged along the length direction of the heating tube 9, and the third flow channel 24 has a second connecting part 30 arranged along the length direction of the heating tube 9. This structure facilitates the assembly of the return tube 8 with the metal shell and the water inlet seat 6. It can use a uniform assembly method along the length of the heating tube 9, which facilitates automated assembly. It also facilitates the insertion of the return tube 8 into the first channel 16 and the second channel 17 with an interference fit. The return tube 8 is tightly inserted into the metal shell to ensure full contact between the return tube 8 and the metal shell, which improves the heat recovery efficiency. At the same time, the assembly difficulty is low and the cost is low.
