[0026] Figure 1 Is the stereogram of the fire structure of the utility model, as Figure 1 Shown in the embodiment, the fire structure includes fire element 3, fire element 3 is equipped with gas transmission channel 310, gas transmission channel 310 is used to transmit gas, fire element 3 is used to connect outer fire cover 1 and inner fire cover 2, gas transmission channel 310 in fire element 3 one end is communicated with fire gas cavity 4, gas transmission channel 310 other end is close to fire outlet 5, so that gas transmission channel 310 can transmit the gas in fire gas cavity 4 to fire outlet 5 place;Fire groove 320 for the flame at fire inlet 6 is introduced to fire outlet 5 to be ignited, realizes fire, fire inlet 6 is directly communicated with fire gas cavity 4, that is to say, the gas flow of fire gas cavity 4 is at fire inlet 6, can be ignited to fire inlet 6.

[0027] Specifically, since the gas transmission channel 310 is located inside the ignition element 3, it is difficult for sundries and water to enter the gas transmission channel 310, so that the gas transmission channel 310 is not blocked, and the normal combustion of the gas is not caused. The ignition inlet 6 and the ignition outlet 5 are separately arranged on the outer fire cover 1 and the inner fire cover 2, that is, if the ignition inlet 6 is arranged on the inner fire cover 2, then the ignition outlet 5 is arranged on the outer fire cover 1, and if the ignition inlet 6 is arranged on the outer fire cover 1, then the ignition outlet 5 is arranged on the inner fire cover 2. The ignition groove 320 is arranged close to the ignition inlet 6 and the ignition outlet 5 at two ends, so that the distance between the ignition groove 320 and the ignition inlet 6 is small, and the distance between the ignition groove 320 and the ignition outlet 5 is small, that is, the distance between the ignition groove 320 and the inner fire cover 2 is small, and the distance between the ignition groove 320 and the outer fire cover 1 is small, so that the flame of the ignition inlet 6 is easily transmitted to the ignition groove 320, and the flame in the ignition groove 320 is easily transmitted to the ignition outlet 5, the transmission effect is good, and the reliability is high.

[0028] The ignition inlet 6 and the ignition gas cavity 4 are arranged on the outer fire cover 1 or the inner fire cover 2 at the same time, the ignition inlet 6 is directly communicated with the ignition gas cavity 4, and the ignition gas cavity 4 provides gas for the ignition inlet 6. When the ignition inlet 6 is arranged on the inner fire cover 2, the ignition gas cavity 4 is arranged on the inner fire cover 2, and at this time, the ignition outlet 5 is arranged on the outer fire cover 1, and the fire is led from the inner fire cover 2 to the outer fire cover 1; when the ignition inlet 6 is arranged on the outer fire cover 1, the ignition gas cavity 4 is arranged on the outer fire cover 1, and at this time, the ignition outlet 5 is arranged on the inner fire cover 2, and the fire is led from the outer fire cover 1 to the inner fire cover 2.

[0029] The shape of the ignition groove 320 is not limited, which can be a long strip or a plurality of round holes, but the overall trend of the ignition groove 320 extends from the position close to the ignition inlet 6 to the position close to the ignition outlet 5.

[0030] Specifically, the shape of the ignition element 3 is not limited, which can be columnar or rod-shaped, as long as the outer fire cover 1 and the inner fire cover 2 can be connected together.

[0031] Specifically, the number of the ignition element 3 is not limited, and the number of the ignition element 3 is at least one, that is, the number of the ignition element 3 can be one; or can be multiple, such as three ignition elements 3, and the ignition elements 3 are distributed along the outer circumference of the inner fire cover 2.

[0032] Further, the ignition groove 320 is arranged on the outer side of the ignition member 3, so that impurities and water are not easy to enter the ignition groove 320, and the ignition groove 320 is not blocked.

The air inlet 330 can be connected with a gas pipeline. The gas directly enters the air transmission channel 310 through the air inlet 330, and can directly provide the ignition gas cavity 4 and the ignition outlet 5 with the gas. In this way, the air supply channel for supplying the ignition gas cavity 4 with the gas does not need to be additionally arranged on the inner fire cover 2, so that the structure of the inner fire cover 2 is simple, and the inner fire cover 2 is easy to manufacture. Further, the upper surface of the inner fire cover 2 is provided with a through hole 220. The center fire cover can be arranged at the through hole 220. The central flame is burned at the through hole 220. Because the gas in the ignition gas cavity 4 is supplied through the air inlet 330, the ignition gas cavity 4 will not be in air communication with the through hole 220, so that the flame is stable, and the combustion effect is good. In addition, the ignition gas cavity 4 can also be supplied with the gas through the air inlet 330, and the air supply channel can be arranged on the inner side wall of the through hole 220.
