1. A combustion chamber, comprising:
a first surrounding plate located on an outer side and a second surrounding plate located on an inner side, wherein a combustion cavity is defined by the second surrounding plate, the first surrounding plate and the second surrounding plate are spaced apart from each other to define an air duct in communication with the combustion cavity, and air duct has an air inlet hole formed in the first surrounding plate, and an air outlet hole formed in the second surrounding plate;
wherein when a negative pressure is formed in the combustion cavity, air in the air duct is delivered into the combustion cavity;
wherein the second surrounding plate comprises a second rear plate, a second left plate connected to a left edge of the second rear plate, a second right plate connected to a right edge of the second rear plate, and a second front plate connected to a front edge of the second left plate and a front edge of the second right plate, and the second rear plate, the second left plate, and the second right plate are integrally formed;
wherein an upper end of the second front plate is formed as a bent plate, and the bent plate is at least partially attached to an inner side wall of the first front plate to close an upper side of the air duct, wherein a heat-insulating air chamber is defined by an upper side of the bent plate and the first front plate and is in no communication with the combustion cavity, and wherein a part of the air inlet hole is adjacent to the bent plate.
