Abstract
A cooling and isolating structure for an external casing of a hot air blowing gun and particularly the structure of the hot air blowing gun at the front end of its interior has a nozzle coupled to the inner barrel, with heating wires disposed inside the inner barrel. An embedded ring is disposed at one end of the nozzle, and a groove is disposed at a position corresponding to the inner side of the external casing of the hot air blowing gun. The insulating embedded plate can be disposed between the nozzle and the external casing of the hot air blowing gun to define an insulated and cooling isolating space to effectively isolate the heat conduction from the nozzle and to prevent the external casing of the hot air blowing gun from being overheated or partially deformed.
