[0026] The outer side of the heat exchanger 3 and below the support frame 14 is fixedly connected with the return pipe 11, one end of the return pipe 11 penetrates the shell 1 and communicates with the inside of the circulating pipe 10.
[0027] The outer side of the second conveying pipe 15 is provided with the heat preservation sleeve 7, the inside of the shell 1 is filled with heat preservation material, and the inside of the heat preservation groove 9 and outside of the circulating pipe 10 is provided with flexible heat preservation filling.

[0030] Working principle:
[0031] In use, the fuel bottle 13 burns to heat the heat exchanger 3 above it. After the heat exchanger 3 absorbs heat, the temperature of the internal heat-conducting liquid rises, and based on the principle of liquid convection, the heated liquid flows upward due to the decrease in density (this is the core power of liquid circulation). The heat exchanger 3 delivers the high-temperature liquid to the exhaust bottle 6 through the first conveying pipe 4. During the process, the solubility of air in water decreases with increasing temperature, and the dissolved air in the heat-conducting liquid will overflow due to the temperature rise; the core function of the exhaust bottle 6 is to collect and discharge these overflowed air to avoid air accumulation in the system to form air resistance.
[0032] After the air is discharged through the exhaust bottle 6, the high-temperature liquid flows into the circulating pipe 10 in the heat preservation mattress 8 through the second conveying pipe 15; when the high-temperature liquid flows in the circulating pipe 10, it transmits heat to the heat preservation mattress 8 through heat conduction, realizing the heating function. At the same time, the low-temperature liquid that has completed heat transfer in the circulating pipe 10 flows back to the heat exchanger 3 through the return pipe 11 below the outer side of the heat exchanger 3 due to the greater density under the action of gravity and system pressure, forming a complete convection circulation. This circulation process continuously supplements the system with high-temperature liquid, ensuring that the heat preservation mattress 8 continuously and stably generates heat.
[0033] The exhaust pipe 2 is used to assist in discharging excess gas in the system, the heat preservation sleeve 7 is used to heat the second conveying pipe 15 to reduce heat loss; the shell 1 is filled with heat preservation material and the bottom is provided with the support frame 14, which also helps to reduce heat loss and improve heat utilization efficiency.
