In the embodiment, the opening and closing of the dust cover 3 are realized through the meshing transmission of the gear 32 and the rack 21, and the dust cover is stable in rotation and easy to operate.

In this embodiment, a heating assembly is disposed in the inner casing 1, and the heating assembly may be heated by a central heating method, a peripheral heating method, an infrared heating method, an electromagnetic heating method, or an air heating method. Smokable material is placed into the filler channel 11 and cryogenically heated by the heating assembly to produce an aerosol.

When the casing 2 is rotated by an external force, the second gear teeth are in meshing transmission with the first gear teeth 321, so that the gear 32 rotates around the first rotating shaft 17, the rotating wheel 33 is driven to rotate around the second rotating shaft, and finally the body 31 is driven to rotate relative to the opening, so as to open or close the open end 111. This embodiment realizes the switching of shield 3 through the meshing transmission of gear 32, convenient operation not only, and the teeth of a cogwheel can play the effect of location at the meshing in-process simultaneously, makes the rotation more accurate and steady. On the other hand, the opening and closing of the dustproof cover are controlled by applying force to the sleeve to enable the sleeve to rotate around the central shaft of the sleeve, the overall appearance of the equipment is hardly influenced in the opening and closing process of the dustproof cover, and the control is easy.

That is, the first gear teeth 321 on the first cover 301 and the first gear teeth 321 on the second cover 302 are respectively located at two sides of the opening end 111. Correspondingly, the casing 2 is correspondingly provided with two arc-shaped racks 21 distributed on two sides of the opening end 111. When the casing 2 is rotated by an external force, the two sections of racks 21 rotate and are in meshing transmission with the corresponding gears 32, so that the two gears 32 rotate in opposite directions, and drive the two bodies 31 to separate from each other to open the open end 111 or to attach to each other to close the open end 111.

When the gear 32 facing the first cover 301 applies a clockwise force to the sleeve 2, the two-segment rack 21 moves clockwise around the center of the sleeve 2 under the drive of the sleeve 2 and meshes with the corresponding gear 32. So that the gear 32 of the first cover 301 rotates clockwise about the first rotation axis 17 and the runner 33 of the first cover 301 rotates clockwise about the second rotation axis. Since the gear 32 of the first cover 301 and the gear 32 of the second cover 302 are respectively located at two opposite sides of the open end 111, i.e. they are in a central symmetrical relationship. Thus, the gear 32 of the second cover 302 rotates counterclockwise about the second rotation axis and the runner 33 of the second cover 302 rotates counterclockwise about the first rotation axis 17, as viewed from the direction facing the gear 32 of the first cover 301.

And a limiting column 12 is arranged on the side edge of the opening end 111 in an outward protruding manner. When the two bodies 31 rotate to be attached to each other, the first slot 311 and the second slot 312 are respectively abutted to two sides of the limiting column 12, so that the rotating positions of the two bodies 31 are limited by the limiting column 12.
