By detecting the water inlet temperature, the working state of the heating component 20 and the water temperature of the inner cavity 5 are regulated.

[0030] The water outlet waterway includes a water outlet channel 15 and a water diversion chamber 16. Several water diversion ports 17 are distributed in a ring around the water diversion nozzle 3. One end of the water outlet channel 15 is connected to the water pipe 13 and the other end is connected to the water diversion chamber 16. The water diversion chamber 16 is connected to the funnel 4 through each water diversion port 17. The hot water can flow evenly to the funnel 4 through the water diversion port 17.
