That is, during the sliding of the control switch unit 30 along the first sliding chute 41, the switch unit 30 receives resistance. The resistance force makes the switch unit 30 unable to switch between the closed state and the open state when the switch unit 30 is not subjected to the external force, thereby improving the connection stability between the switch unit 30 and the sliding cover 40. In addition, the switch unit 30 needs to overcome the resistance applied by the deformation portion 60 when being switched from the on state to the off state, and the switch unit 30 also needs to overcome the resistance applied by the deformation portion 60 when being switched from the off state to the on state, so that the operation feeling of the user is enhanced, and the user can be prompted that the switch unit 30 is switched from the on state to the off state or that the switch unit 30 is switched from the off state to the on state.

After the user has finished drawing in, with reference to figure 13, the aerosol-forming substrate 20 is removed from the receptacle 12, the annular portion 52 is not restricted in its radial movement, so that the elastic portion 70 can move in the radial direction and consequently the base 14 can move in the axial direction (shown in the direction X in figure 13) relative to the heating body 13. Referring to fig. 13 and 14, the control switch unit 30 slides in the third slide groove 43 in the axial direction in the direction toward the cigarette box 11 (indicated by a direction in fig. 13 and 14), and the switch unit 30 is switched from the off state to the on state. Referring to fig. 15 and 16, the third axial extension 16 moves axially, and consequently the seat 14 moves axially with respect to the heating body 13, the seat 14 is lifted, and under the effect of the inclined surface, the elastic portion 70 moves radially, and the elastic element 51 is compressed, generating an elastic force.

When the switch unit 30 is released, the elastic portion 70 is reset by the elastic force and moves in the direction opposite to the direction C in fig. 16, and then the base 14 is driven to move in the direction (indicated by the direction B in fig. 13) toward the switch unit 30 in the axial direction, and the switch unit 30 is switched from the on state to the off state.

In other embodiments, the annular portion 52 may not be provided. After the aerosol-forming substrate 20 has been inserted into the receptacle 12, the user then performs a suction operation, which operates the aerosol-forming substrate 20 to move in the circumferential direction relative to the heating body 13 for a certain period of time, so that the aerosol-forming substrate 20 is released from the heating body 13. Then the control switch unit 30 slides in the third sliding groove 43 along the axial direction in the direction towards the cigarette cabin 11, and the aerosol-forming substrate 20 can be lifted simultaneously in the lifting process of the base 14, so that the extraction of the aerosol-forming substrate 20 is realized.

Preferably, in the gas mist generating apparatus 10 of the present invention, the base 14 is at least partially bonded to the outer peripheral surface of the heating body 13. In this embodiment, the base 14 is completely attached to the outer peripheral surface of the heating body 13. After the aerosol-forming substrate 20 is taken out from the accommodating portion 12, since the base 14 is attached to the outer peripheral surface of the heating body 13, the surface of the heating body 13 can be cleaned while the base 14 is moved in the axial direction relative to the heating body 13. The base 14 reciprocates up and down relative to the heating body 13 along the axial direction, so that the surface of the heating body 13 can be cleaned in a reciprocating manner, and the aerosol generating device 10 is more favorably cleaned. For example, the control switch unit 30 reciprocates in the third chute 43 by the elastic portion 70, and the surface of the heating body 13 is cleaned reciprocally.

Referring to fig. 10, embodiments of the present invention also provide an aerosol-generating system 1 comprising: the aerosol-generating device 10 of any of the embodiments described above; the gas mist-forming substrate 20 is placed in the housing 12, the base 14 is movable in the axial direction with respect to the heating body 13 after the gas mist-forming substrate 20 is taken out of the housing 12, and the gas mist-forming substrate 20 placed in the housing 12 prevents the base 14 from moving in the axial direction with respect to the heating body 13 after the gas mist-forming substrate 20 is placed in the housing 12, and the base 14 is kept stationary with respect to the heating body 13.

In summary, the above-mentioned embodiments are provided only for illustrating the principles and effects of the present invention, and not for limiting the present invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
