Similarly, the connecting plate is arranged between the innermost disc 3 and the fire cover 1.

[0029] Specifically, the air inlet hole 4 and the first fire hole 5 are staggered with each other to prevent interference between the air inlet hole 4 and the first gas supply channel 7.

[0030] Specifically, the fire cover 1 and the disc 3 are of an integrated structure, which is convenient for overall manufacturing; or can be a detachable structure, the disc 3 and the fire cover 1 and the disc 3 and the disc 3 are connected together through the connecting plate, and specifically, the disc 3 and the disc 3 and the fire cover 1 and the disc 3 are connected by bolts.

[0032] Figure 3 is a top view of the second embodiment of the disc fire cover of the utility model, Figure 4This is a perspective view of a second embodiment of the disc-shaped flame cap of this utility model from one angle, as shown below. Figure 3 and 4 In the illustrated embodiment, the outermost disc-shaped plate 3 has a wavy edge 10 on its outer surface. Multiple first flame outlet holes 5 are also provided on the wavy edge 10, increasing the area of ​​the outer surface of the disc-shaped plate 3.

[0035] Specifically, the principle of this utility model is to set at least one disc-shaped plate 3, and to set multiple first flame outlet holes 5 on the disc-shaped plate 3. The first flame outlet holes 5 are connected to the air inlet channel 6 of the flame cap 1 through the first air supply channel 7, so that there are multiple air supply channels and high air pressure. Since the disc-shaped plate 3 is arranged sequentially from the inside to the outside on the outer circumference of the flame cap 1, the first air supply channel 7 becomes longer, so the air pressure inside the disc-shaped flame cap is high and the firepower is sufficient.

[0036] Operation process: 1. The gas in the intake channel 6 enters the first flame outlet 5 through the first gas supply channel 7, and the gas in the intake channel 6 enters the second flame outlet 2 through the second gas supply channel 8; 2. The second flame outlet 2 is ignited using an ignition needle (not shown). Since the second flame outlet 2 is very close to the first flame outlet 5, the flame from the second flame outlet 2 ignites the first flame outlet 5 near the burner cap 1. Since the two adjacent discs 3 are very close, the first flame outlet 5 ignites the remaining first flame outlet 5 from the inside out. The discs 3 increase the number and length of the gas supply channels, resulting in higher gas pressure, stronger firepower, higher thermal efficiency, and less smoke.
