Combustor, combustion assembly and cooking utensil

The burner comprises a first body and a second body which are matched with each other, a containing cavity is formed between the first body and the second body, the containing cavity is used for being communicated with a gas pipeline, and a separation structure is formed on at least one of the first body and the second body. The separating structure forms at least one fire hole set communicated with the outside at the combination position of the first body and the second body, each fire hole set comprises a main fire hole and branch fire holes, one end of each main fire hole is communicated with the containing cavity, the other end of each main fire hole is communicated with the corresponding branch fire hole, and the branch fire holes are formed in the two axial sides of each main fire hole respectively. The flow directions of fuel gas of the branch fire holes located on the two axial sides of the main fire hole are different, so that the directions of the fuel gas flowing out of the branch fire holes of all the fire hole sets are not parallel, the possibility that the fuel gas makes contact with one another is increased, mixing of the fuel gas is facilitated, and then the combustion performance and the fire transfer performance of the combustor are improved.
