a fire splitting assembly, which is arranged in the box; wherein an intake passage is formed between the fire splitting assembly and an inner bottom surface of the box, a first end of the intake passage communicates with the set of intake holes, and a second end of the intake passage communicates with an installation position of the first combustor; and wherein an exhaust passage is formed between the fire splitting assembly and the top plate, a first end of the exhaust passage communicates with the set of exhaust holes, and a second end of the exhaust passage communicates with the installation position of the first combustor;
wherein the set of intake holes comprise a first intake hole, the set of exhaust holes comprise a first exhaust hole, and the fire splitting assembly comprises a first fire splitting plate; wherein the first fire splitting plate, the first exhaust hole and the first intake hole are all located on one side of the first combustor; a first passage portion of the exhaust passage is formed between the first fire splitting plate and the top plate; the first and second ends of the first passage portion communicate with the first exhaust hole and the installation position of the first combustor respectively; and wherein a first passage section of the intake passage is formed between the first fire splitting plate and the inner bottom surface of the box, and the first and second ends of the first passage section communicate with the first intake hole and the installation position of the first combustor respectively.

2. The combustion device according to claim 1 , wherein the first fire splitting plate comprises:
a first plate body portion, which is arranged spaced apart from the inner bottom surface of the box, wherein a first end of the first plate body portion abuts against the top plate, and a second end of the first plate body portion extends toward the installation position of the first combustor; and
a first support portion, wherein the first plate body portion is matched with the inner bottom surface of the box through the first support portion, wherein an edge of the first plate body portion abuts against a side wall of the box; and/or
the first plate body portion is of a first bend structure.

3. The combustion device according to claim 1 , wherein the first exhaust hole is a first elongated hole, and the first elongated hole extends in a length direction of the first combustor; and/or
the number of the first intake holes is plural, and each of the first intake holes is provided on a side wall of the box and/or the inner bottom surface of the box.

4. The combustion device according to claim 1 , wherein the set of intake holes comprise a second intake hole, the set of exhaust holes comprise a second exhaust hole, and the fire splitting assembly comprises a second fire splitting plate; wherein the second fire splitting plate, the second exhaust hole and the second intake hole are all located on the other side of the first combustor; a second passage portion of the exhaust passage is formed between the second fire splitting plate and the top plate; the first and second ends of the second passage portion communicate with the second exhaust hole and the installation position of the first combustor respectively; a second passage section of the intake passage is formed between the second fire splitting plate and the inner bottom surface of the box, and the first and second ends of the second passage section communicate with the second intake hole and the installation position of the first combustor respectively.

5. The combustion device according to claim 4 , wherein the second fire splitting plate comprises:
a second plate body portion, which is arranged spaced apart from the inner bottom surface of the box, wherein a first end of the second plate body portion abuts against the top plate, and a second end of the second plate body portion extends toward the installation position of the first combustor; and
a second support portion, wherein the second plate body portion is matched with the inner bottom surface of the box through the second support portion, wherein an edge of the second plate body portion abuts against a side wall of the box; and/or
the second plate body portion is of a second bend structure.

6. The combustion device according to claim 4 , wherein the second exhaust hole is a second elongated hole, and the second elongated hole extends in a length direction of the first combustor; and/or
the number of the second intake holes is plural, and each of the second intake holes is provided on a side wall of the box and/or the inner bottom surface of the box.

7. The combustion device according to claim 1 , wherein the combustion assembly further comprises a second combustion assembly, and the second combustion assembly comprises:
a second combustor, which is arranged in a cooking cavity of the cooking apparatus and is configured to heat the cooking cavity; and
a radiation plate, which is arranged between the second combustor and a top plate of the cooking cavity; wherein the radiation plate is a bend plate and extends in a length direction of the cooking cavity, and flames of the second combustor flow along a side surface of the radiation plate that is away from the top plate of the cooking cavity.

8. The combustion device according to claim 7 , wherein the radiation plate comprises:
a main plate body, which is arranged spaced apart from the top plate of the cooking cavity; wherein the second combustor is located on a side of the main plate body that is away from the top plate of the cooking cavity and is matched with the main plate body;
a first plate body, which is of a first bend structure and is connected to one side of the main plate body; and
a second plate body, which is of a second bend structure and is connected to the other side of the main plate body, wherein the first plate body comprises:
a first portion, which is connected to the one side of the main plate body and is arranged in a direction approaching the top plate of the cooking cavity; and
a second portion, which is connected to the first portion and bends in a direction away from the top plate of the cooking cavity, wherein a first connection structure is provided on the second portion, and the first connection structure is configured to connect with the top plate of the cooking cavity.
