[0052] It should be noted that when the cross section is circular, the cross-sectional size refers to the diameter; when the cross section is polygonal, the cross-sectional size refers to the side length.

[0053] The cooking device provided by the utility model is provided with a fuel holder 2 and a fuel block 3. After the fuel block 3 is ignited, the lunch box body 4 can be heated by an open flame. The fuel holder 2 is a tapered structure, which is conducive to the flame being able to maximize contact with the bottom of the lunch box body 4 during combustion, thereby improving the heat transfer effect. The lunch box body 4 includes a first barrel section, a gradually expanding transition section, and a second barrel section connected in sequence from the bottom to the top. When the cross-sectional size of the second barrel section is greater than the cross-sectional size of the limiting through hole and greater than the cross-sectional size of the first barrel section, the first barrel section can be located in the inner cavity of the supporting outer box 1, close to the fuel holder 2 and the fuel block 3 can be used to hold food for heating; at the same time, the limiting through hole can realize the limiting effect of the lunch box body 4, so that the lunch box body 4 remains unchanged in a specific position, making the open flame heating cooking more stable, and this limiting effect can prevent the gas generated by the open flame from being discharged from the limiting through hole; in addition, the top surface of the supporting outer box 1 except the limiting through hole can isolate part of the combustion heat, and there is a certain interval between the top end of the second barrel section and the top surface of the supporting outer box 1, and this interval can effectively block heat transfer. Under the joint effect of the above conditions, it can prevent the user from being scalded when taking out the lunch box.

[0054] Furthermore, the supporting outer box 1 comprises a supporting outer box body and an outer box cover arranged at the top open end of the supporting outer box body; the center of the outer box cover is provided with the limiting through hole.

[0055] Furthermore, a supporting portion is circumferentially provided on the inner edge of the top end of the supporting outer box body.

[0056] In the utility model, the support part is used to support the outer box cover. When the limiting through hole on the outer box cover limits the lunch box body 4, the supporting force can be enhanced and it will not collapse.

[0057] Furthermore, 4-8 air holes are formed on the side wall of the supporting outer box 1, for example, 4, 5, 6, 7 or 8 air holes.

[0058] Furthermore, the supporting outer box 1 is a hexagonal prism structure.

[0068] Furthermore, embossing is provided on the side wall of the first tube section of the lunch box body 4.

[0069] Furthermore, the lunch box body 4 is made of aluminum foil.

[0070] Aluminum foil is a light and soft metal material. It is a composite material composed of a layer of aluminum foil and a layer of tin foil, mainly made of aluminum. Aluminum foil is usually shiny on one side and gray on the other side. It has good moisture-proof, heat-insulating and fresh-keeping properties. Aluminum foil has good thermal conductivity and heat insulation because it contains aluminum foil. This allows it to effectively protect food from high temperatures during cooking, while also allowing food to be heated evenly, maintaining the original flavor of the food and the freshness and taste of the food.

[0071] Furthermore, the second tube section of the lunch box body 4 is a straight tube structure, such as Figure 7 and Figure 8 shown.

[0072] Furthermore, an outer edge of one end of the second barrel section away from the gradually diverging transition section is provided with a rim along the circumferential direction.

[0073] In the utility model, when the outer edge of the second barrel section away from the gradually expanding transition section is provided with a rim along the circumferential direction, it is easier for a user to pick up the lunch box.

[0074] Furthermore, the distance between the edge and the top surface of the supporting outer box 1 is 0.8-1 cm, for example, it can be 0.8 cm, 0.9 cm or 1 cm.

[0079] In the utility model, an outer edge is arranged at the open end of the fuel holder 2, so as to facilitate assembly operation and facilitate later adjustment.

[0080] Furthermore, the ratio of the diameter of the sealing end of the fuel tray 2 to the outer diameter of the outer edge is (0.6-0.632):1, for example, it can be 0.6:1, 0.61:1, 0.614:1, 0.62:1, 0.63:1 or 0.632:1.

[0081] Furthermore, the outer diameter of the outer edge of the fuel tray 2 is 5.7-6 cm, for example, 5.7 cm, 5.8 cm, 5.9 cm or 6 cm.

[0082] Furthermore, the distance between the open end of the fuel holder 2 and the bottom surface of the first barrel section is 2-3 cm, for example, 2 cm, 2.2 cm, 2.5 cm, 2.8 cm or 3 cm.

[0083] In the utility model, when the distance between the open end of the fuel tray 2 and the bottom surface of the first barrel section is 2-3 cm, at this time, the distance between the fuel block 3 and the bottom surface of the first barrel section after being placed on the fuel tray 2 is moderate, which can quickly cook the food and avoid being undercooked without burning.

[0084] Furthermore, the axis of the fuel tray 2 coincides with the axis of the lunch box body 4 .

[0085] In the present invention, when the axis of the fuel tray 2 coincides with the axis of the lunch box body 4, the cooking effect is better.

[0086] Furthermore, the cooking device also includes an ignition component 6, and the ignition component 6 is used to ignite the fuel block 3.

[0087] In the utility model, the ignition element 6 (such as a candle) is first ignited, and then the fuel block 3 is ignited by the ignition element 6, so that the user can avoid scalding his hands when directly igniting the fuel block 3 with a lighter or other products.

[0088] Furthermore, the ignition element 6 is a candle.
