Example

The actual operation process of the new model is as follows:

Before starting the fire, install the four screws in the bidirectional mounting brackets on the outside of the stove, and replace the longer screws depending on the terrain to set up the stove; put the charcoal in the round metal air inlet in the stove Put the charcoal on the rack and ignite the fire. After the charcoal is lit, slowly add more charcoal. After the fire is enough, put the pot on the 3 L-shaped pots and the grilling mesh support frame. The circular air inlet hole enters, and goes up through the circular metal grille with holes. The air path touches the charcoal and then continues to move upward until the wind blows to the bottom of the pot and then it is discharged from the air outlet. The bottom is getting hotter and hotter to increase the chimney effect; if it rains suddenly in the middle of the barbecue or the position of the barbecue needs to be changed, the stove can be moved without being burned by holding the handle; The circular metal grille with the holes falls into the ash receiving slot at the bottom of the furnace. After the roasting is over, the ash powder is poured into the garbage bag. (Detailed picture of the actual operation of the cooking pot)

The structure and combination of the straight handle and the placement position of the straight handle are as follows. Fix one L-shaped handle respectively. The 1 wing of the iron piece and the 1 wing of another L-shaped fixed iron piece are combined in a T-shape, and a piece of solid wood is clamped between the two wings, and then fastened with screws, washers and nuts to form a T-shaped handle , and then fix the T-shaped handle on the outer side wall of the stove with screws and nuts to form a straight-line handle. The functions of the straight-line handle are as follows, including "easy to carry in peacetime", "easy to move when lighting a fire and prevent burns" The three functions of "hand", "if it rains or other factors when lighting a fire, you can move the stove quickly", when lighting a fire, you can move the stove without being burned by holding the part of the solid wood handle with one hand; the structure of the ring-shaped handle is composed The part is as follows, consisting of 2 lifting ring screws, 2 nuts, and 2 S-shaped iron hooks to form 2 lifting ring handles . The nuts are respectively fixed on the furnace wall above the outer side of the furnace, and the fixed position of the plane projection is the two intersection points of the line cutting through the center of the furnace circle and the furnace wall (but this line needs to avoid L S-shaped pans and grilling mesh support frame), and the lifting ring screw is fixed on the outside of the stove, the nut is fixed on the inner side of the stove, and 2 S-shaped iron hooks are used to hook the 2 lifting ring screws to move the stove, the lifting ring The functions of the type handle are as follows. There are three functions: "easy to carry in peacetime", "easy to move when lighting a fire and prevent burns to hands", "if it rains or other factors when lighting a fire, the stove can be moved quickly". Use the S-shaped hook with both hands to hook the part of the two rings to move the stove without getting burned.
