The gas outlet is installed in the middle of the flame-gathering sleeve, and the gas outlet has a gas outlet hole. The lower end of the flame-gathering sleeve or the gas outlet is connected to the upper end of the sleeve. The middle of the sleeve has an air inlet hole, and the lower part of the sleeve is equipped with an air inlet assembly, which includes a flow restrictor, a seal, a tail cap, and a filter.

[0003] In existing technologies, the flame emitted after ignition at the vent is blue, which is a relatively uniform color and cannot be customized with different colors such as flame color changing. Furthermore, the blue flame is difficult to see clearly in sunlight, which can easily lead to burns and other safety accidents for users, resulting in low safety.

[0004] In one existing structure, the venting part is inserted into the inner wall of the flame-gathering sleeve. A main vent is located in the center of the venting part, and an auxiliary vent is formed between the outer side of the venting part and the inner wall of the flame-gathering sleeve. In this structure, both the main vent and the auxiliary vent produce a single blue flame upon ignition.

[0005] In another configuration, the burner head further includes a connecting seat, with the gas outlet mounted on the connecting seat, and a flame-gathering sleeve installed between the connecting seat and the sleeve. The gas outlet has a main gas outlet in its center, and an auxiliary gas outlet for assisted ignition is provided between the gas outlet and the upper inner wall of the connecting seat. Preferably, the upper end of the gas outlet has a gas-gathering ring, and an upper gas outlet is provided between the gas-gathering ring and the gas outlet, with the auxiliary gas outlet communicating with the upper gas outlet. The bottom of the gas outlet has an air inlet area. In this configuration, both the main gas outlet and the auxiliary gas outlet produce a single blue flame after ignition. Summary of the Invention
