It also includes a socket for connecting the spray head and the air mixing tube and having a first straight through hole. The upper end of the socket has a concave cavity for partially embedding the spray head, and the spray head is tightly fitted in the concave cavity. The upper end of the socket abuts against the bottom wall of the heat insulation cup. The bottom of the heat insulation cup has a through hole for the lower end of the socket to pass through, and the part of the lower end of the socket passing through the through hole is inserted into the upper end of the air mixing tube, and the upper end of the air mixing tube abuts against the lower end of the heat insulation cup.

[0003] Technical problems existing in the existing structure: The installation requirements between the spray head and the socket are high, and it is easy for the two components to be not properly installed. For example, the spray head is not perpendicular, resulting in slanting fire and potential safety hazards; when the spray head is provided with a flow dividing hole, if the spray head is not perpendicular, it will cause the gas flow dividing hole to be too large or too small, making the flame unstable and affecting the ignition success rate; the yield rate is relatively low.
