The invention provides a smoking device. The smoking device comprises a shell, a heat transfer assembly and a feeding assembly, wherein the shell has a heating end and a transmission end; the heatingend is provided with a heating cavity, and the transmission end is provided with a transmission cavity; the heat transfer assembly is located in the shell, and the heat transfer assembly is provided with a heat conduction piece penetrating into the heating cavity from the transmission cavity, and the heat conduction piece and the inner wall of the heating cavity form a containing gap; the feedingassembly is connected with the transmission end, and the feeding assembly is provided with a combustion space; and one end of the heat transfer assembly absorbs heat from the combustion space, and theheat is transferred to the heat conduction piece. The smoking device provided by the invention is heated from the interior of a smoke cartridge, and when the smoke cartridge is located in the containing gap, the heat conduction piece is inserted into the smoke cartridge, the high temperature on the heat conduction piece causes the smoke cartridge to generate inhalable gas, and the heat loss is effectively reduced.
