Torch 1 still has gas jar 3, and gas jar 3 sets up inside 2 shells and with gas channel 4 intercommunication, and gas flows to gas cavity 5 from gas jar 3 via gas channel 4.

As shown in fig. 1-3, the torch 1 further comprises a gas channel 4, and the gas outlet of the gas channel 4 extending into the gas chamber 5 is divided into a main gas outlet 61 and an auxiliary gas outlet 62. The gas flow rate of the main gas outlet 61 is greater than that of the auxiliary gas outlet 62, and the auxiliary gas outlet 62 is disposed closer to the fire outlet 7 than the main gas outlet 61.

In the present embodiment, as shown in fig. 1 to 3, the torch 1 includes a gas chamber 5 and a fire outlet 7 provided at the top end of the gas chamber 5. A main gas outlet 61 and an auxiliary gas outlet 62 are respectively arranged in the gas chamber 5 of the torch 1, wherein the gas flow of the main gas outlet 61 is larger than that of the auxiliary gas outlet 62. On this basis, the auxiliary air outlets 62 are disposed closer to the fire outlet 7 than the main air outlets 61. The gas flows out from the fire outlet 7 at the top of the gas chamber 5 and is ignited to form the main flame of the torch 1. At this time, the gas ignited at the fire outlet 7 is composed of two parts, one part flows out from the main gas outlet 61 which is far away from the fire outlet 7 and has a large flow rate, and the other part flows out from the auxiliary gas outlet 62 which is near to the fire outlet 7 and has a small flow rate.
