[0032] In this embodiment, the size of the burning tube 18 is 190-230 mm.

[0033] Furthermore, the heat dissipation component includes a heat dissipation fan 26, a heat dissipation fan air guide box 32, a heat sink 27, a limit plate 33, a semiconductor temperature difference power generation sheet 28, an auxiliary heat conduction plate 29 and a heat sink 30.

[0034] In this embodiment, the thermocouple sensor 31 extends to the interior of the burning tube 18, which is convenient for directly measuring the flame temperature. The concave platform 4 mainly provides heat for the semiconductor thermoelectric power generation sheet 28 and the auxiliary heat conducting plate 29.

[0040] Furthermore, the thermocouple sensor 31 extends into the heat sink 30 , the head of the thermocouple sensor 31 is located 10-20 mm from the top of the burning tube 18 , and the cooking heat conducting plate 10 is connected to the top of the heat sink 30 .

[0041] In the present utility model, the circuit connections of the lithium battery 5, the oil pump 6, the circuit board 8, the voltage control box 9, the combustion control switch 13, the power switch 14, the charging port 15, the voltage and power display panel 16, the ignition plug 22, the combustion-supporting fan 25, the heat dissipation fan 26 and the semiconductor thermoelectric power generation chip 28 are all existing technologies, so the circuit connection principles are not described here.

[0042] In the present invention, heat energy is generated by the combustion mechanism, which is then transferred to the cooking heat-conducting plate 10 for heating, thereby facilitating the grilling of food. At the same time, the residual heat after heating the cooking heat-conducting plate 10 can also be transported to the serpentine tube, so that the serpentine tube transfers the heat energy into the oven 2, thereby facilitating the heating of food. Finally, part of the heat energy is discharged through the heat dissipation holes 12 to achieve heating. In this way, the technical problems of low heating efficiency, single function and inability to achieve self-power supply of the existing diesel heating furnace structure are effectively solved.

[0043] In the present invention, there are three key points of the semiconductor thermoelectric power generation 28: first, the hot end of the semiconductor thermoelectric power generation 28 is in close contact with the heat sink 30; the cold end is in close contact with the heat sink with the heat dissipation fan 26, so that a temperature difference is generated at both ends of the power generation sheet, thereby generating electrical energy; in order to generate enough electricity, multiple power generation sheets need to be connected in series and parallel to generate sufficient voltage and current, and both the cold end and the hot end are required to be flat; second, a stable thermal field. The heat exchanger used in this device is a heat sink 30 with a concave platform. After the heat energy generated by combustion passes through the fins inside the heat sink 30, it will transfer the heat to the heat sink 30, and then transfer it to the auxiliary heat conduction plate 29 connected only to the concave platform. The auxiliary heat conduction plate 29 with high and uniform temperature transfers the heat to multiple series-parallel power generation sheets; third, a stable cold field. The combination of the heat dissipation fan 26, the heat dissipation fan air guide box 32, and the heat sink 27 is to create a uniform cold field.

[0044] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the utility model.
