A flow guiding slope is formed to reduce the injection pressure of the gas at the outlet end, so that the gas of the ejector tube 110 flows more uniformly.

As shown in FIG. 2, which is a left side view of the two adjacent fire extinguishers 103 and 104, please refer to FIG. 1. In this embodiment, the fire extinguisher 100 can be formed by the first housing 100A being fastened to the second housing 100B. That is, the cavity of the ejector tube 110 is surrounded by the first casing 100A and the second casing 100B, and the inlet pipe through hole 131 and the outlet pipe through hole 132 penetrate the first casing 100A and the second casing 100B. The firearm 100 further includes a top plate 11 that is capped over the three ejector tubes 110 and has a plurality of fire holes 111B.

The length of the hole 111B is the smallest, so that the flame generated by each set of the fire-extinguishing portion 111A has a clear limit, and each set of the fire-extinguishing portion 111A can form a plurality of group-shaped flames to reduce the overall height of the flame and the temperature of the flame, thereby improving the firearm. The adaptability of the NOx emissions from the combustion of the flame.

In a variable embodiment, the fire holes 111B at both ends have the same length and the shortest length, and the remaining fire holes 111B (the fire holes not at the both ends) have the same length (as shown in FIGS. 7 and 8), and the present embodiment is lowered. The flame height and the emission of nitrogen oxides simultaneously reduce manufacturing costs.

In another variable embodiment, as shown in FIG. 9, the length of the fire hole 111B near the intermediate position of the fire-extinguishing portion 111A is long, and the length of the fire hole 111B near the both ends becomes short, so as to be generated. The flame boundary is more pronounced and better forms a group flame, thereby reducing the height of the flame to a greater extent.

The shape of the fire hole 111B on the top plate 11 in the present application includes, but is not limited to, the shape and length described above. The fire hole 111B of the present application is changed in length to make the flame boundary generated by each set of the fire generating portion 111A more conspicuous. Other structures that change the length and arrangement of the fire holes 111B to change the flame boundary of each of the fire-extinguishing portions 111A or the fire holes 111B to reduce the flame height are also included in the scope of protection of the present application.

The fire holes 111B in the fire exit portion 111A at the two sides of the 114 are densely arranged. That is, the density of the fire hole 111B disposed adjacent to the air outlet 114 of the ejector tube 110 is smaller than the density of the fire hole 111B disposed at both sides of the air outlet 114 of the ejector tube 110. Thereby, more gas can be caused to flow to the densely arranged fire holes 111B on both sides to generate a flame, so that the top plate 11 produces a uniform fire.

In a variable embodiment, as shown in FIG. 8, the interval between the fire exit holes 111B in the fire exit portions 111A corresponding to the position above the air outlet 114 of the ejector tube 110 on the top plate 11 is large, thereby making it sparse. arrangement. The interval between the respective fire exit holes 111B in the fire exit portion 111A at the position of the air outlets 114 on both sides of the discharge tube 110 on the top plate 11 is small, so as to be densely arranged.

Preferably, as shown in FIG. 7 to FIG. 11 , in order to set the flame between the set of fire-extinguishing portions 111A to have a limit, the spacing between each set of fire-extinguishing portions 111A may be greater than each fire in each set of fire-extinguishing portions 111A. The pitch of the holes 111B.

In one embodiment, as shown in FIG. 9, both sides of the fire hole 111B are outwardly convex. The fire hole 111B is convex outward by the both sides so that the fire hole 111B forms an elliptical structure to increase the area of the fire hole 111B, thereby increasing the ejection strength. The two sides of the fire hole 111B can be understood to correspond to the positions of both ends in the longitudinal direction of the top plate 11.

In a variable embodiment, as shown in FIG. 10, the fire holes 111B have projections, and the projections of the adjacent fire holes 111B are staggered. The fire hole 111B is provided with a plurality of protrusions in the middle portion, so that the fire hole 111B is increased in area of the protrusion compared to when no protrusion is provided, so that the overall area of the fire hole 111B is increased, thereby enhancing the injection strength, and the phase is enhanced. The protrusions of the adjacent two fire holes 111B are staggered to increase the number and density of the fire holes 111B.
