The cigarette 200 can be inserted on the heat conducting structure 30, and the laser generating structure 50 can emit laser beams irradiated on the heat conducting structure 30, so that the heat conducting structure 30 can bake the cigarette 200 by using the heat effect of high energy generation of the laser beams, and smoke for a user to suck is generated. Because the laser beam provides energy, the heat conducting structure 30 can be rapidly heated to reach a required temperature value in a short time, and compared with the prior art, the smoke generating speed in the early stage of baking is increased, so that the consistency of the smoke output of the cigarette 200 is ensured.

Referring to fig. 1-3, the housing 10 is a hollow cylindrical shell structure with an open end, and includes an open end 12 for inserting the cigarette 200, a closed end 14 opposite to the open end 12, and a containing cavity 16 communicating the open end 12 and the closed end 14, wherein the aperture of the open end 12 is larger than the outer diameter of the cigarette 200, and one end of the cigarette 200 can be inserted into the containing cavity 16 from the open end 12 to be baked in the containing cavity 16.

As shown in fig. 2 and 4, in an embodiment, at least one fastening protrusion 74 is protruded from a sidewall of the fixing hole 72 along a circumferential direction, and a fastening groove 323 matching with the fastening protrusion 74 is formed in an outer wall of the heat conducting structure 30 inserted into one end of the fixing hole 72 along the circumferential direction. In this way, when the heat-conducting body 32 is retained in the fixing hole 72, the fastening groove 323 of the heat-conducting structure 30 is engaged with the fastening protrusion 74 of the sidewall of the fixing hole 72, and the fastening protrusion 74 is retained in the fastening groove 323, so as to fix the heat-conducting structure 30 to the fixing member 70 in the axial direction.
