The outer fire cover body includes an outer fire cover and a fire cover seat. The outer surfaces of the outer fire cover and the fire cover seat are both set to semicircular arc shapes. An air mixing chamber is formed between the outer fire cover and the fire cover seat. An installation cavity is provided in the middle of the outer fire cover body. Several air inlet ducts are arranged around the air mixing chamber and the installation cavity, and an air replenishment hole is provided between two adjacent air inlet ducts.

[0004] For another example, the patent document with publication number CN104534472B discloses a cylindrical fire cover and a stove burner for a stove burner, comprising a cylindrical body with a lower opening, fire holes evenly distributed in a circular pattern on the upper part of the cylindrical body, and an interface on the lower opening of the cylindrical body; it is characterized in that it also includes an air guide hole for secondary air, the lower end of the secondary air guide hole is located on the lower end surface of the cylindrical body radially outside the interface, and the upper end cooperates with the cylindrical body at the air outlet end of the fire hole.

[0005] However, in the above technology, the top of the inner fire cover is sealed, which is not conducive to the air entering the inner fire cover and mixing with the gas for combustion.

[0006] Therefore, a burner fire cover is proposed to solve the above technical problems. Utility Model Content

[0007] In order to solve the above technical problems, the purpose of the present utility model is to provide a burner fire cover, which has the advantages of facilitating the entry of air and mixing with gas for combustion, thereby improving the combustion rate of gas.

[0008] The technical solution adopted by the present invention to solve the problem is: a burner fire cover, comprising: a cover body, a bottom of the cover body is provided with a groove opening downward, a side wall of the groove is provided with a plurality of fire holes distributed in a ring array, a mounting through hole is provided in the cover body, a bracket is provided in the mounting through hole, and the cover plate is also included, the cover plate is connected to the bracket, and a gap is left between the cover plate and the cover body.

[0009] As a further improvement of the above technical solution, it also includes a connecting piece, and the cover plate is connected to the bracket through the connecting piece.

[0010] As a further improvement of the above technical solution, the connecting member is a screw, the screw head of the connecting member is arranged on the bracket, and the connecting member is threadedly connected to the cover plate.

[0011] As a further improvement of the above technical solution, the cover plate includes a connecting column, which is fixedly arranged at the bottom center of the cover plate. The bracket is provided with a through hole, and the connecting column is plugged into the through hole.

[0012] As a further improvement of the above technical solution, a boss is provided on the connecting column, and the boss abuts against the bracket.

[0013] The beneficial effect of the utility model is that, by providing a gap at the top of the cover body, air can be replenished into the cover body through the gap for a second time, thereby ensuring full combustion of the gas. BRIEF DESCRIPTION OF THE DRAWINGS
