The box body 1 is provided with a heat supply assembly, the heat supply assembly has a medium channel, and a plurality of fins are arranged on the surface of the medium channel. When the equipment works, the heat will be transmitted from the thermoelectric generator inner machine 2 to the heat supply assembly through the medium channel, and the fins arranged on the heat supply assembly can cooperate with a plurality of exhaust fans 16 to dissipate the heat to the outside. Specifically, the thermoelectric generator inner machine 2 can be placed in the containing cavity, and when working, the thermoelectric generator inner machine 2 can be taken out and separated from the box body 1. The thermoelectric generator inner machine 2 is provided with a mounting cavity 21, a heat collecting column 211 is arranged in the mounting cavity 21, the outer surface of the heat collecting column 211 is provided with a power generation sheet, the other end of the power generation sheet is connected with a water cooling assembly, the water cooling assembly is connected with the heat supply assembly through a pipeline, forming a circulating medium system, the circulating medium system increases the temperature difference of the power generation sheet and carries away the heat, and the heat is transmitted to the outside through the heat supply assembly.

[0031] The box body 1 further comprises a water pump 14, which is arranged in the box body 1, and specifically arranged at the bottom of the box body 1. The water pump 14 is connected with the water cooling assembly through a pipeline of the heat supply assembly, and provides power for the circulating medium system. More preferably, a water tank 15 can be further arranged on the circulating medium system, to ensure the sufficiency of the medium in the circulating system. The medium can be water or antifreeze. At the same time, the water tank 15 can be arranged at the upper end of the box body 1, and an opening is arranged on the water tank 15, which is sealed by a cover. During the use of the equipment, the medium will inevitably be consumed, and when the medium is insufficient, it can be manually added. A plurality of air vents can be further arranged on the upper surface of the water tank 15, to prevent the medium pipeline from expanding and the pressure from increasing during work, so that the medium penetrates out of some gaps.

[0032] Specifically, the upper end of the installation cavity 21 is provided with a first fan 22, and the shells of the thermoelectric generator inner machines 2 on the two sides of the first fan 22 are provided with air outlet holes 24. The lower end of the installation cavity 21 is provided with air inlet holes 23 on the shells of the thermoelectric generator inner machines 2 on the two sides. In the working state of the device, the first fan 22 rotates at a normal speed, and the external air is introduced from the lower shell of the thermoelectric generator inner machine 2. The airflow passes through the air inlet of the installation cavity 21, then vertically flows upward, and finally flows out from the outlet at the upper end of the installation cavity 21, and is discharged from the air outlet holes 24 on the shells of the thermoelectric generator inner machines 2 on the two sides of the first fan 22. The first fan 22 can provide sufficient oxygen for the combustion in the installation cavity 21.

[0033] Further, the thermoelectric generator inner machine 2 further comprises a detection assembly, which comprises a temperature sensor and a first controller. The first controller is electrically connected with the temperature sensor and the first fan 22. The first controller receives the signal of the temperature sensor to control the first fan 22, effectively preventing the thermoelectric generator from being damaged and stopping working due to high temperature.

The second controller is connected with the temperature sensor and the burner head 26 at one end of the pipeline. When the temperature is too high, the electromagnetic valve is adjusted to be small, so that the flame is reduced. There are three gears designed here. The device box 1 is also provided with a display screen to provide the current power supply wattage. If the wattage is too low, the electromagnetic valve opening can also be manually increased to increase the flame.

[0035] Further, the thermoelectric generator inner machine 2 is also provided with a fire observation window 25 for observing the size of the flame.

Similarly, a plurality of electric heating wires can also be arranged in the box 1. When the electric quantity is sufficient, the heating can be realized without relying on the heat of combustion, that is, the electric heating wires are directly driven by electric energy to be heated continuously, and when the temperature reaches a certain value, the heating function is realized by blowing the heat generated by the electric heating wires by the fan.

[0036] Specifically, the box 1 is also provided with a pipeline compartment 12, and the thermoelectric generator inner machine 2 is provided with a pipeline in the pipeline compartment 12. One end of the pipeline is connected with the heating assembly of the box 1. When the device is in use, the other end of the pipeline is used to connect the water cooling assembly to realize the communication between the water cooling assembly and the heating assembly. When the device is not in use, the pipeline is stored in the pipeline compartment 12. The pipeline is stored by using rollers, which is convenient and simple.
