A safety valve 4 is installed on the side of the boiling bucket 1. The safety valve 4 is connected to the upper heating water tank 105 to ensure the safety of heating water in the upper heating water tank 105. 05 is installed with a first temperature sensor 5 in the inner cavity, and a second temperature sensor 6 is installed in the inner cavity of the lower heating water tank 106. The temperature displays of the first temperature sensor 5 and the second temperature sensor 6 are respectively fixedly installed on the outer wall of the boiling barrel 1. The water temperatures in the upper heating water tank 105 and the lower heating water tank 106 can be monitored in real time through the first temperature sensor 5 and the second temperature sensor 6.
