The heating device is a heater used in the prior art to heat the circulating liquid medium. The pump body is a device used in the prior art to pump liquid. The structure and principle thereof will not be described one by one here.

[0043] The heating tube 113 is arranged in a spiral structure, and one end of the heating tube 113 outside the heat-insulating jacket 103 is connected to a liquid-adding tube, and a first valve is installed on the liquid-adding tube.
