Electric heating type blowtorch

The invention provides an electric heating type blowtorch, and relates to the technical field of blowtorches. The electric heating type blowtorch comprises a heating cabin, a fixing groove is formed in the rear side wall of the heating cabin, a nitrogen cylinder is arranged on the upper surface of the fixing groove, a guide rod is slidably connected to the interior of the fixing groove, a spring is fixedly connected between the front side end of the guide rod and the inner wall of the fixing groove, and a rear seat is fixedly connected to the rear end face of the guide rod. A spraying barrel is fixedly connected to the front side wall of the heating cabin, a heat insulation head is arranged at the front side end of the spraying barrel, and heat insulation layers are arranged on the inner walls of the spraying barrel and the heating cabin. By generating eddy current and resistance heat, nitrogen blown out is heated, although the reached temperature is lower than that of a fuel blowtorch, the nitrogen is comple
