[0026] A modular briefcase-style barbecue grill includes a grilling mesh 1 for supporting skewers and a charcoal mesh 2 for supporting fuel; it also includes a grill side panel 3, an ash collection tray 4, a column 5, a connecting rod 6, and supporting feet 7; wherein the upper and lower sides of the grill side panel 3 are provided with skirts 31 extending inward to the inside of the grill side panel 3, and the skirts 31 are provided with a plurality of connecting holes 33; the grilling mesh 1 is provided on the upper surface of the grill side panel 3; the charcoal mesh 2 is provided inside the grill side panel 3, and the charcoal mesh 2 is positioned above the lower skirt 31 of the grill side panel 3; the ash collection tray 4 is located below the grill side panel 3, and the column 5 is located between the ash collection tray 4 and the grill side panel 3; the connecting rod 6 passes through the connecting holes 33 on the grill side panel 3 from top to bottom and connects to the column 5 below the grill side panel 3; the supporting feet 7 pass through the ash collection tray 4 from bottom to top and connect to the column 5 above the ash collection tray 4. The ash receiving tray 4 and the furnace side plate 3 are supported and connected by a column 5, leaving a certain gap. Air can freely enter the furnace side plate 3 from below, helping the fuel above the charcoal mesh 2 to burn fully. In addition, the ash produced by the fuel combustion will fall onto the ash receiving tray 4, avoiding environmental pollution and reducing the risk of fire. It can also protect the ground or the supporting table from being burned.

[0027] The furnace side panel 3 is a square box-shaped structure. The vertical axis of the furnace side panel 3 allows for air circulation, as hot air rises to the area above the grill 1, while air enters below the charcoal grill 2, balancing the low air pressure within the furnace side panel 3 and creating airflow circulation. The sides of the furnace side panel 3 are composed of frame plates 32. Each frame plate 32 is square, with skirts 31 bending inwards along its upper and lower edges. Connecting holes 33 are located at both ends of the skirts 31. When adjacent frame plates 32 are combined, the connecting holes 33 at adjacent ends overlap, facilitating the insertion of connecting rods 6. These, along with the uprights 5, clamp and connect adjacent frame plates 32.

[0029] The charcoal mesh 2 is also square in shape, and the bottom of the charcoal mesh 2 corresponds to the bottom of the furnace side plate 3; the edge of the charcoal mesh 2 is provided with a mesh frame, and the four corners of the mesh frame are provided with arc-shaped notches corresponding to the connecting rod 6.

[0030] One end of the connecting rod 6 is provided with a nut, which presses down the grill rack 1 and clamps it above the oven side plate 3; the other end of the connecting rod 6 is threaded to the column 5, which facilitates the connection and separation of the column 5 and the connecting rod; the bottom end of the column 5 is threaded to the support foot 7.

[0031] The ash receiving tray 4 is generally square in shape, and four support feet 7 are provided at the four corners of the ash receiving tray 4.

[0032] It should be noted that in some other embodiments, the side panel of the oven can also be set as a triangular frame, or a pentagonal frame, or a hexagonal frame, or other regular polygons; the overall shape of the side panel of the oven does not affect the function of the barbecue oven.

[0033] During implementation, by setting up a column 5 between the ash receiving tray 4 and the furnace side plate 3, a gap is created between the ash receiving tray 4 and the furnace side plate 3, allowing air to directly enter the furnace side plate 3 through the gap, ensuring efficient air circulation and helping the fuel to burn completely. The ash receiving tray 4 is set below the column 5 to catch the ash and slag falling from the charcoal mesh 2, avoiding environmental pollution and reducing the risk of fire. The furnace side plate 3 is designed to include four separate frame plates 32, making it easy to disassemble, store, and carry after disassembly.
