At this point, the base 14 remains stationary with respect to the heating body 13, while the heating body 13 does not disturb the heating of the aerosol-generating substrate 20, and thus the generated aerosol is provided to the user for smoking.

After the user quits smoking, as shown in FIG. 13, the movement of the annular portion 52 in the radial direction is not limited after the aerosol-forming substrate 20 is removed from the containing portion 12, thus the elastic portion 70 can move in the radial direction, and then, the base 14 can move in the axial direction ( as shown by the arrow X in Fig. 13) with respect to the heating body 13. As shown in Fig. 13 and 14, the switching unit 30 is axially shifted towards the cigarette compartment 11 (as shown by arrow A in FIG. 13 and FIG. 14) in the third slot, and the switching unit 30 is switched from an off state to an on state. With reference to FIG. 15 and FIG. 16, the third axially extending portion 16 moves in the axial direction, then, the base 14 moves in the axial direction relative to the heating body 13, the base 14 is lifted by the action of the inclined plane, the elastic part 70 moves in the radial direction, and the elastic member 51 is compressed to create elastic force.

The switching block 30 is released, under the action of the elastic force, the elastic part 70 returns to its original position, moves in the direction opposite to the direction C in FIG. 16, and then causes the base 14 to move in the axial direction towards the switching unit 30 (as shown by arrow B in FIG. 13), and the switching unit 30 switches from the on state to the off state.

In other embodiments, the annular portion 52 may be omitted. Then, after the aerosol-generating substrate 20 is inserted into the housing portion 12 and the user finishes smoking, the aerosol-generating substrate 20 can be moved circumferentially with respect to the heating body 13 for a certain period of time, and the aerosol-forming substrate 20 the aerosol is separated from the heating body 13. Then, the switching unit 30 is axially shifted towards the cigarette compartment 11 in the third slot 43, and when the base 14 is lifted, the aerosol-forming substrate 20 can be simultaneously lifted, and thus the substrate 20 , forming an aerosol, can be taken out.

Preferably, at least part of the base 14 in the aerosol generating device 10 according to the invention is attached to the outer peripheral surface of the heating body 13. In an embodiment, the base 14 is fully attached to the outer peripheral surface of the heating body 13. After the aerosol generating substrate 20 , is taken out from the housing part 12, since the base 14 is attached to the outer peripheral surface of the heating body 13, the surface of the heating body 13 is cleaned when the base 14 is moved in the axial direction relative to the heating body 13. The base 14 is moved up and down in a reciprocating movement in the axial direction relative to the heating body 13, so that it is possible to clean the surface of the heating body 13 by reciprocating, which is preferable for cleaning the aerosol generating device 10. For example, under the action of the elastic part 70, the switching unit 30 is moved in the third slot 43 in a reciprocating motion, thereby cleaning the surface of the heating body 13.

As shown in FIG. 10, according to an embodiment of the invention, an aerosol generating system 1 is also provided, comprising: an aerosol generating apparatus 10 according to any of the above embodiments; and an aerosol-forming substrate 20 disposed in the housing portion 12. After the aerosol-forming substrate 20 is removed from the housing portion 12, the base 14 can move in the axial direction relative to the heating body 13; after being placed in the containing part 12, the aerosol-forming substrate 20 placed in the containing part 12 can prevent the base 14 from moving in the axial direction relative to the heating body 13, and the base 14 remains stationary relative to the heating body 13.

Thus, the above embodiments are provided only to illustrate the principles and effects of the invention and not to limit it. Specialists in the field of technology can modify or change the above-described embodiments without deviating from the scope and spirit of the invention. Accordingly, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and the technical idea are covered by the claims.
