[0023] In the embodiment, the cooking heat-conducting plate 1 adopts aviation aluminum material with temperature resistance of 2000 degrees Celsius, diameter of 170-200 millimeters, thickness of 3-4 millimeters, and 3-7 recessed grooves arranged in the middle, to avoid deformation of the cooking heat-conducting plate due to uneven heating, the air guide box is a cuboid, and the return fire disc is a cylinder with diameter of 120-150 millimeters.

[0024] In the embodiment, first, the ignition plug 7 is powered on, and after the ignition plug 7 reaches 850℃, fuel is introduced into the oil guide hole 8 through the oil pump and the oil filter, then the fuel is atomized by the fuel atomizing net, and under the action of the combustion fan 10, the ignition plug 7 ignites the atomized fuel, so that the fuel can be fully burned, and the heat after combustion moves upward in the afterburning pipe 2 to heat the cooking heat conducting plate 1, and heat the thermocouple sensor 18 arranged inside the heat sink and located at the top of the afterburning pipe 2. After the thermocouple sensor 18 senses the temperature change, it is judged that the ignition is successful and the current of the ignition plug 7 is cut off. The temperature of the heated cooking heat conducting plate 1 can reach 450℃, which can be used for cooking and roasting.

[0025] Further, the heat sink includes a heat dissipation fan 11, a heat sink fin 12, a limiting plate 13, an auxiliary heat conducting plate 14 and a heat sink 15.

When the temperature of the power generation sheet 16 and the auxiliary heat conducting plate 14 is too low, it indicates that the power generation is insufficient. The power generation sheet 16 directly converts heat energy into electric energy by using the Seebeck effect, so as to store the electric energy in the lithium battery.

[0031] In the embodiment, the heat dissipation fins can improve the heat dissipation effect.

[0032] Further, the concave platform 17 is composed of two bosses, and the width of each side of the two bosses is 18-25 mm.

[0033] In the embodiment, the bosses can prevent the temperature of the power generation sheet 16 and the auxiliary heat conduction plate 14 from being too high to cause damage.

[0034] Further, the total thickness of the concave platform 17 is 12-16 mm, and the total width is 80-100 mm; the width of the concave platform 17 is the total width minus the width of the boss.

[0035] Further, the bottom plate 20 is arranged below the air guide box 4, and the bottom plate 20 is provided with an air inlet 21, and the air inlet end of the combustion-supporting fan 10 is located at the air inlet 21.
