[0039] In a preferred embodiment, the connecting head 2 is detachably connected to the lower ends of the heating tube 4 and the heat dissipation cold water pipe 3, and the first mounting groove 21 is used for fixed installation with the heating tube 4. A plug-in column 211 is provided in the first mounting groove 21, and the lower end of the heating tube 4 is sleeved on the plug-in column 211. A first sealing member is provided between the heating tube 4 and the plug-in column 211.

[0040] A spiral spoiler tube 8 is provided inside the heating tube 4, and a thread groove 81 is wound around the outer surface of the spiral spoiler tube 8. The bottom end of the spiral spoiler tube 8 is plugged into the plug-in column 211, and a diversion hole 82 is provided at the bottom end of the spiral spoiler tube 8.

[0041] A supporting rib 2111 is provided inside the plug-in column 211 , and the supporting rib 2111 is used to support the spiral spoiler tube 8 .

[0042] After passing through the plug-in column 211, the water flows into the heating channel 41 and rotates and rises along the threaded groove 81. This process can make the water flow fully and evenly heated, and ensures that the hot water output by the faucet will not be hot or cold, providing a good user experience.

[0043] The second mounting groove 22 is used for fixed installation with the heat dissipation cold water pipe 3, and a second sealing member 33 is provided between the heat dissipation cold water pipe 3 and the second mounting groove 22. In order to enhance the sealing performance between the heat dissipation cold water pipe 3 and the second mounting groove 22, a plurality of second sealing members 33 can be provided, which are respectively provided at the bottom end of the heat dissipation cold water pipe 3 and the inner side of the second mounting groove 22. After the water flows into the heat dissipation cold water pipe 3, it flows through the mixing chamber 23 and the plug-in column 211 in sequence, and then enters the water storage channel and the heating pipe 4 to be heated.
