[0006] Preferably, the protection assembly includes two heat-insulating shells, and the two heat-insulating shells are both sleeved on the outside of the air intake duct.

[0007] Preferably, two adjustment connecting plates are fixedly connected between the two insulation shells, and the two air intake ducts are threadedly connected with positioning nuts at both ends close to the insulation shells. The purpose of this arrangement is: the air intake duct can be insulated by the protective component to prevent the user from accidentally touching the air intake duct after tempering and getting burned, and the positioning point of the insulation shell can be adjusted by the positioning nut to make the insulation shell in a position that is easier for the user to touch.
