The invention relates to a smoke detection device, and particularly discloses a smoke sulfur trioxide sampling gun. The smoke sulfur trioxide sampling gun comprises a sampling pipe and a filtering cylinder. A heat-insulating shell is arranged outside the sampling pipe and the filtering cylinder. A smoke channel is formed in the heat-insulating shell. A heat-tracing smoke inlet pipe and a heat-tracing smoke outlet pipe are arranged on the heat-insulating shell. The smoke sulfur trioxide sampling gun has the advantages that to-be-detected smoke can be utilized for heat tracing, and the sampling gun is not provided with a heat-insulating layer and a heat-racing belt, so that weight and size of the sampling gun are reduced greatly, and fault correcting of the sampling gun is benefited; heat energy of the smoke is fully utilized for heat tracing, and heat tracing energy consumption is reduced; the sampling gun is ingenious and simple in overall structure, convenient to operate and beneficial to industrial populari
