In this embodiment, the torch 10 has a rectangular shape, so the pry-mounting frame 12 and the shield 16 also have a rectangular shape, and the shield 16 has upper and lower openings in the vertical direction. Each venturi burner 20 has an air inlet portion 20a for injecting air and an outlet portion 20b for outputting mixed gas, and each venturi burner 20 includes a nozzle 24 and a mixing pipe 26, and the mixing pipe 26 is, for example, a square pipe. The nozzle 24 is provided in the air inlet portion 20a, and one end of the nozzle 24 communicates with the air supply duct 23 and the other end thereof extends into the mixing pipe 26. The mixing tubes 26 form at least a part of the protective cover 16, for example, all the mixing tubes 26 form a bottom protective cover unit of the protective cover 16, the inner side of the mixing tubes 26 facing the flame chamber 22 is opened with flame holes, and the flame holes form an outlet 20b for outputting mixed gas.

In other words, the mixing tube 26 is not only part of the shroud 16, but is also a mixing carrier for the venturi burner 20. This kind of design is integrated to a side's siphunculus with the shrink mixing section and the diffusion mixing section of traditional venturi combustor in, has reduced and has arranged the space requirement, saves a wall section of thick bamboo, can enlarge the size of protection casing moreover, enlarges the flame district, increases torch combustion space, has reduced the inside heat intensity that holds in flame district, can effectively reduce flame length, burning noise. As shown in fig. 5, the mixing pipe 26 is a rectangular pipe having a rectangular parallelepiped structure as a whole, and inner plates 50 are provided on at least two opposite inner side walls of the mixing pipe 26 on the side of the air inlet portion 20 a. In the illustrated embodiment, the inner plates 50 are provided on the four inner side walls of the mixing pipe 26 on the side of the intake portion 20 a. The inner plates 50 on every two opposite inner side walls of the inner plates 50 on the four inner side walls are inwards bent towards each other to form bent plates, so that each inner plate 50 comprises a first bent part 50a and a second bent part 50b, a contraction mixing section is formed between the four first bent parts 50a, a diffusion mixing section is formed between the four second bent parts 50b, and a space part of one side, far away from the air inlet part 20a, of the inner plate 50 forms a premixing section, thereby forming a Venturi structure.

It should be understood that the inner plates 50 are disposed on four inner sidewalls of the mixing pipe 26 on the side of the air inlet 20a in the above embodiments, and in other embodiments, other embodiments are also possible according to specific design requirements, for example, the inner plates 50 are disposed on two opposite inner sidewalls of the mixing pipe 26 on the side of the air inlet 20a, and the two inner plates 50 on the two opposite inner sidewalls are bent oppositely.

In the illustrated embodiment, the lances 52 are mounted within the flame ports such that the lances 52 project from the inner wall surface of the mixing tube 26. This arrangement can keep the flame away from the inner wall surface of the mixing pipe 26, and avoid damage to the inner wall surface.

As shown in FIG. 1, a number of mixing tubes 26 are disposed on all four sidewalls of the torch 10. More specifically, each of the four side walls is formed by stacking a plurality of mixing pipes 26 in the vertical direction, the number of the stacking of the mixing pipes 26 in each side wall is the same, and the mixing pipes 26 are arranged in the horizontal direction and are uniformly aligned in the vertical direction. Wherein, each layer of any side wall is formed by connecting two mixing pipes 26 side by side, the connecting end of the two mixing pipes 26 is closed, the other end of the mixing pipe 26 opposite to the connecting end is an open structure, and the nozzle 24 is arranged at the open structure.

Of the four side walls of the torch 10, the flame holes on two opposite side walls jet the flame oppositely, and the flame holes on the other two opposite side walls jet the flame oppositely. For example, all the mixing tubes 26 on two opposite sidewalls are respectively disposed oppositely, and the flame holes on the mixing tubes 26 on two opposite sidewalls are respectively corresponding in position, so that during combustion, the flame holes on two opposite sidewalls form a pair spray. The flame can inhibit the spraying length of the flame of the other side in the opposite spraying, and prevent the flame from extending to contact with the opposite wall surface, so that the temperature of the wall cylinder exceeds the standard and the color is changed.

The nozzle 24 sprays fuel gas and injects air into the mixing pipe 26 for mixing, and then the mixed gas enters the flame cavity 22 from the flame holes for combustion. The design enables the injection type combustion device to inject air in a larger range, on one hand, the number of the burners can be obviously increased, the insufficient air injection amount of each burner is avoided, the mixed gas is injected and combusted from a plurality of flame holes, the flame is uniformly distributed on the inner wall surface of the protective cover formed by the whole mixing pipe 26, and the combustion flame is relatively shorter; on the other hand, at the periphery of the protection cover 16 formed by the mixing pipes 26, due to the injection action of the venturi burner 20, besides a part of peripheral air is injected into the venturi burner 20 to participate in combustion, a large amount of peripheral cold air can be led to the outside of the protection cover 16, that is, if the outer side of the mixing pipes 26 moves, so that the heat of the mixing pipes 26 is dissipated. The mixed gas flows through the inside of the mixing pipe 26, and the heat radiation effect of the protection mask 16 itself can be further enhanced.
