The utility model discloses a first gas distribution disc structure, a combustor and a gas cooker. The first gas distribution disc structure comprises a gas distribution disc, the gas distribution disc comprises a first cavity part and a first injection pipe arranged at the bottom of the first cavity part in a protruding mode, the first cavity part is provided with a first fuel gas cavity, the first injection pipe comprises a gas outlet end located in the first fuel gas cavity, and the outer side of the gas outlet end is connected with the bottom face of the first fuel gas cavity through a cambered surface. Therefore, according to the first gas distribution disc structure, the combustor and the gas cooker, the gas distribution disc can be separated from the combustor; when fuel gas entersthe first fuel gas cavity through the gas outlet end of the first injection pipe, due to the fact that the outer side of the gas outlet end of the first injection pipe is connected with the bottom face of the first fuel gas cavity in a cambered surface transition mode, the flow loss of the fuel gas when the fuel gas enters the first fuel gas cavity can be reduced, and then the heat load of the combustor is improved.
