[0037] Referring to Fig. 6 and Fig. 7 in conjunction with Fig. 2, Fig. 17 and Fig. 18, in the embodiment, the sliding cover 40 is further provided with a first sliding groove 41, wherein the first sliding groove 41 and the through hole 45 are arranged in the radial direction (as shown in a direction Y in Fig. 6). In the embodiment, the first sliding groove 41 and the through hole 45 are spaced from each other in the radial direction, and in other embodiments, the first sliding groove and the through hole are adjacently connected in the radial direction, for example, the first sliding groove and the through hole are in contact with each other in the radial direction, and projections of the first sliding groove and the through hole in the axial direction may be a line. The switch unit 30 is inserted into the first sliding groove 41, and is capable of sliding along the first sliding groove 41 till covering the through hole 45, as shown in Fig. 4, a direction C in Fig. 4 is a movement direction of the switch unit 30, alternatively, the switch unit 30 is capable of sliding along the first sliding groove 41 till the switch unit 30 and the through hole 45 are arranged in the radial direction (as shown in Fig. 2), for example, the switch unit 30 and the through hole 45 are spaced from each other in the radial direction, or are adjacently connected in the radial direction, or for example, the switch unit 30 and the through hole 45 are in contact with each other in the radial direction, and projections of the switch unit 30 and the through hole 45 in the axial direction may be a line.

[0038] Continuing to refer to Fig. 7 in conjunction with Fig. 4, in the axial direction, the switch unit 30 is provided with an operating part 31 located outside the sliding cover 40 and a clamping part 32 located inside the sliding cover 40. By controlling the operating part 31, the switch unit 30 may slide along the first sliding groove 41 till covering the through hole 45, so that the switch unit 30 is in the switch-on state; and alternatively, the operating part 31 is controlled so that the switch unit 30 may slide along the first sliding groove 41 till the switch unit 30 and the through hole 45 are arranged in the radial direction, for example, the switch unit 30 and the through hole 45 are spaced from each other in the radial direction, and thus, the switch unit 30 is in the switch-off state. Referring to Fig. 8 and Fig. 18, a part, facing the sliding cover 40, of the cigarette compartment 11 is provided with a second sliding groove 42, and in an extending direction (as shown in a direction Y in Fig. 8) of the second sliding groove 42, the second sliding groove 42 is provided with a first part 42b and a second part 42a, wherein the extending direction of the second sliding groove 42 is consistent to an extending direction of the first sliding groove 41.

[0039] When the switch unit 30 is in the switch-on state, the operating part 31 covers the through hole 45 in the sliding cover 40, the clamping part 32 is located on the first part 42b of the second sliding groove 42, and is capable of being separated from the first part 42b in the axial direction, then movement of the sliding cover 40 in the axial direction is not limited, the sliding cover 40 is capable of being separated from the cigarette compartment 11 in the axial direction, and the user may clean the base 14 in the sliding cover 40.

[0040] When the switch unit 30 is in the switch-off state, the operating part 31 and the through hole 45 are arranged in the radial direction, the clamping part 32 is located on the second part 42a and is connected with the second part 42a in the axial direction in a clamped mode, movement of the sliding cover 40 in the axial direction is limited, and the sliding cover 40 may not be separated from the cigarette compartment 11 in the axial direction. In the embodiment, when the switch unit 30 is in the switch-off state, the operating part 31 and the through hole 45 are spaced from each other in the radial direction; and in other embodiments, the operating part and the through hole are adjacently connected in the radial direction, for example, the operating part and the through hole are in contact with each other in the radial direction, projections of the operating part and the through hole in the axial direction may be a line, and may also be an area, and for example, the area is elliptical.

[0041] When the switch unit 30 is in the switch-off state, the aerosol forming substrate 20 may be inserted in the through hole 45 in the sliding cover 40 to be placed in the containing part 12 of the cigarette compartment 11, the heating body 13 heats the aerosol forming substrate 20 to generate aerosol for the user to smoke; in a smoking process, the aerosol forming substrate 20 abuts against the operating part 31 in the radial direction, the aerosol forming substrate 20 prevents the operating part 31 from moving towards the through hole 45 in the sliding cover 40, and the switch unit 30 may not be switched to the switch-on state from the switch-off state, so that the process of atomization of the aerosol forming substrate 20 by the aerosol generating device 10 may not be affected, and normal use of the aerosol generating device 10 is not interfered. In other embodiments, in the smoking process, the aerosol forming substrate and the operating part are arranged in the radial direction, and may not abut against each other, for example, the aerosol forming substrate and the operating part are spaced from each other in the radial direction.

[0042] Referring to Fig. 8, in the embodiment, a width of the first part 42b is greater than that of the clamping part 32, a width of the second part 42a is smaller than that of the clamping part 32, and the switch unit 30 slides to the second part 42a from the first part 42b to be switched from the switch-on state to the switch-off state. The clamping part 32 is capable of penetrating through the first part 42b to do up-down motion in the axial direction, and the clamping part 32 is not capable of penetrating through the second part 42a to do up-down motion in the axial direction.

[0043] In the embodiment, each of the first part 42b and the second part 42a is provided with two areas which are axisymmetric, the clamping part 32 is located in the two areas of the first part 42b and the two areas of the second part 42a respectively, and by such an arrangement, the stability of the clamping part 32 sliding along the second sliding groove 42 may be improved.

[0044] Referring to Fig. 4 and Fig. 9 in conjunction with Fig. 18, in the embodiment, the sliding cover 40 is further provided with a deformation part 60, the deformation part 60 is attached to the switch unit 30, and when the switch unit 30 is switched between the switch-on state and the switch-off state, the deformation part 60 is capable of applying resistance to the switch unit 30. That is, when the switch unit 30 is controlled to slide along the first sliding groove 41, the switch unit 30 is subjected to resistance. Due to existence of the resistance, the switch unit 30 is not capable of being switched between the switch-off state and the switch-on state randomly when the switch unit 30 is not subjected to an external acting force, so that the stability of connection between the switch unit 30 and the sliding cover 40 is improved. In addition, the switch unit 30 needs to overcome the resistance applied by the deformation part 60 when switched from the switch-on state to the switch-off state, and also needs to overcome the resistance applied by the deformation part 60 when switched from the switch-off state to the switch-on state, so that the control feeling of the user is improved, and the user may be prompted that the switch unit 30 has been switched from the switch-on state to the switch-off state, or the switch unit 30 has been switched from the switch-off state to the switch-on state.

[0045] Referring to Fig. 9, in the embodiment, the operating part 31 and the clamping part 32 of the switch unit 30 are connected through a connecting part 33, the connecting part 33 is capable of sliding along the first sliding groove 41, and the deformation part 60 is attached to the connecting part 33 of the switch unit 30. In the radial direction (as shown in a direction Y in Fig. 9), the deformation part 60 comprises a first area 61, a second area 62 and a third area 63; in the switch-on state, the first area 61 is attached to the switch unit 30; in the switch-off state, the third area 63 is attached to the switch unit 30, and a width of the second area 62 is smaller than a width of the first area 61 and a width of the third area 63 respectively.

[0046] Then, the switch unit 30 may pass through the second area 62 when moving between the first area 61 and the third area 63, because the width of the second area 62 is smaller than the width of the first area 61 and the width of the third area 63 respectively, the switch unit 30 may be extruded, the deformation part 60 applies resistance to the switch unit 30, and the switch unit 30 moves to the first area 61 or the third area 63 after overcoming the resistance of the second area 62.

[0047] It should be noted that the specific structure of the deformation part is not limited thereto, but may also be in other structural forms, and the deformation part is capable of applying the resistance to the switch unit.

[0048] In the embodiment, the deformation part 60 is made of an elastic material, wherein the deformation part 60 is arranged in the first sliding groove 41. When sliding along the first sliding groove 41, the switch unit 30 may be subjected to the resistance applied by the deformation part 60.

[0049] Referring to Fig. 4 and Fig. 5, in the embodiment, the base 14 is suspended in the sliding cover 40, which is beneficial to cleaning the base 14 after the base 14 is separated from the heating body 13 in the axial direction. A mode of connection between the base 14 and the sliding cover 40 is not defined, in the embodiment, the base 14 is connected with the through hole 45 through an axial extension part 44, and the axial extension part is used for containing the aerosol forming substrate 20. The axial extension part 44 is spaced from an inner wall of the sliding cover 40 in the radial direction, and thus, when the sliding cover 40 is capable of covering the cigarette compartment 11, the base 14 and the axial extension part 44 are located in the containing part 12 of the cigarette compartment 11. In conjunction with Fig. 6, in the embodiment, a part of the base 14 is connected with the axial extension part 44. It may be understood that the axial extension part 44 partially extends in a circumferential direction, and the base 14 and the axial extension part 44 wholly form an L shape (as shown in Fig. 5). After the base 14 is separated from the heating body 13 in the axial direction, an exposed area is large, so that the user cleans the base 14 conveniently.

[0050] Referring to Fig. 10 and Fig. 11, in other embodiments, the switch unit 30 is connected with the base 14, a part of the switch unit 30 is located outside the aerosol generating device 10 and is used for driving the base 14 to move relative to the heating body 13 in the axial direction (as shown in a direction X in Fig. 10 and Fig. 11). In the embodiment, the switch unit 30 is capable of moving, in the axial direction, towards the cigarette compartment 11 (as shown in a direction A in Fig. 10) so as to drive the base 14 to move in the axial direction relative to the heating body 13.

[0051] Continuing to refer to Fig. 11, in the embodiment, an elastic part 70 is arranged in the cigarette compartment 11, one end of the elastic part 70 is connected with the base 14, the other end of the elastic part 70 is connected with the inner wall of the cigarette compartment 11, and when the switch unit 30 is switched between the switch-on state and the switch-off state, the elastic part 70 is capable of applying resistance to the base 14. Due to existence of the resistance, when not subjected to the external acting force, the switch unit 30 is not capable of being switched between the switch-off state and the switch-on state randomly, and thus the stability of connection between the switch unit 30 and the base 14 is improved. In addition, the switch unit 30 needs to overcome the resistance applied by the elastic part 70 when switched from the switch-on state to the switch-off state, and also needs to overcome the resistance applied by the elastic part 70 when switched from the switch-off state to the switch-on state, the control feeling of the user is improved, and the user may be prompted that the switch unit 30 has been switched from the switch-on state to the switch-off state, or has been switched from the switch-off state to the switch-on state.

[0052] Relative positions of the elastic part 70 and the base 14 are not defined, in the embodiment, when the switch unit 30 drives the base 14 to move in the axial direction relative to the heating body 13, the elastic part 70 is capable of moving in the radial direction (as shown in a direction Y in Fig. 11), and the radial direction is perpendicular to the axial direction. In other embodiments, when the switch unit 30 drives the base 14 to move in the axial direction relative to the heating body 13, the elastic part 70 may move in the axial direction.

[0053] Specifically, referring to Fig. 11, the elastic part 70 comprises a first axial extension part 50 and an elastic piece 51, and an extending direction of the first axial extension part 50 is consistent to an extending direction of the heating body 13. One end of the elastic piece 51 is connected with the first axial extension part 50, and the other end of the elastic piece 51 is connected with the inner wall of the cigarette compartment 11. The base 14 is provided with a second axial extension part 15, the first axial extension part 50 is provided with an inclined plane, the second axial extension part 15 abuts against the inclined plane, and the elastic piece 51 and the second axial extension part 15 are located on different sides of the first axial extension part 50. Due to existence of the inclined plane, movement of the base 14 in the axial direction is converted into movement of the elastic part 70 in the radial direction. In other embodiments, the movement of the base in the axial direction is converted into the movement of the elastic part in the radial direction by other structural forms.

[0054] In the embodiment, the elastic piece 51 extends in the radial direction (as shown in the direction Y in Fig. 11). In the other embodiments, the elastic piece 51 may extend in the other directions, is capable of being compressed to facilitate movement of the elastic part 70 in the radial direction, and is capable of resetting the elastic part 70.

[0055] Referring to Fig. 12, a third axial extension part 16 is arranged on a side, facing away from the second axial extension part 15, of the base 14, and is connected with the switch unit 30, and an extending direction of the third axial extension part 16 is consistent to the extending direction of the heating body 13. In addition, the aerosol generating device 10 further comprises a body part 101. Referring to Fig. 10, the body part 101 is provided with a third sliding groove 43, the third sliding groove 43 extends in the axial direction, and the switch unit 30 is inserted into the third sliding groove 43, and is capable of sliding along the third sliding groove 43 to be switched between the switch-on state and the switch-off state.

[0056] In addition, the aerosol generating device 10 further comprises an annular part 52 which is arranged on the elastic part 70. When the switch unit 30 is in the switch-on state, in the radial direction, at least part of the annular part 52 is located outside the containing part 12; and when the switch unit 30 is in the switch-off state, the annular part 52 is located on the containing part 12, so that the aerosol forming substrate 20 may be inserted into and contained in the containing part 12.

[0057] Specifically, referring to Fig. 11, after the aerosol forming substrate 20 is inserted into the containing part 12 along the annular part 52, the annular part 52 sleeves the aerosol forming substrate 20, the aerosol forming substrate 20 prevents the elastic part 70 from moving in the radial direction, so that the switch unit 30 may not be switched between the switch-off state and the switch-on state, further, the process of the atomization of the aerosol forming substrate 20 by the aerosol generating device 10 may not be affected, and the normal use of the aerosol generating device 10 is not interfered. At the moment, the base 14 remains stationary relative to the heating body 13, heating of the heating body 13 to the aerosol forming substrate 20 is not affected, and thus, generated aerosol is provided for the user to smoke.

[0058] After the user completes smoking, referring to Fig. 13, movement of the annular part 52 in the radial direction is not limited after the aerosol forming substrate 20 is taken out from the containing part 12, thus, the elastic part 70 is capable of moving in the radial direction, and then, the base 14 is capable of moving in the axial direction (as shown in a direction X in Fig. 13) relative to the heating body 13. Referring to Fig. 13 and Fig. 14, the switch unit 30 is controlled to slide, in the axial direction, towards the cigarette compartment 11 (as shown in a direction A in Fig. 13 and Fig. 14) in the third sliding groove, and the switch unit 30 is switched to the switch-on state from the switch-off state. Referring to Fig. 15 and Fig. 16, the third axial extension part 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, under the action of the inclined plane, the elastic part 70 moves in the radial direction, and the elastic piece 51 is compressed to generate an elastic force.

[0059] The switch unit 30 is released, under the action of the elastic force, the elastic part 70 resets, moves in a direction opposite to a direction C in Fig. 16, and then drives the base 14 to move, in the axial direction, towards the switch unit 30 (as shown in a direction B in Fig. 13), and the switch unit 30 is switched to the switch-off state from the switch-on state.

[0060] In other embodiments, the annular part 52 may not be arranged. Then, after the aerosol forming substrate 20 is inserted into the containing part 12, the user completes smoking, the aerosol forming substrate 20 may be operated to move for a period of time in the circumferential direction relative to the heating body 13, and the aerosol forming substrate 20 is separated from the heating body 13. Then, the switch unit 30 is controlled to slide, in the axial direction, towards the cigarette compartment 11 in the third sliding groove 43, when the base 14 is lifted, the aerosol forming substrate 20 may be lifted simultaneously, and thus, the aerosol forming substrate 20 may be taken out.

[0061] Preferably, at least part of the base 14 in the aerosol generating device 10 of the present invention is attached to an outer peripheral surface of the heating body 13. In the 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 containing part 12, because the base 14 is attached to the outer peripheral surface of the heating body 13, a surface of the heating body 13 is cleaned when the base 14 moves in the axial direction relative to the heating body 13. The base 14 moves up and down in a reciprocating manner in the axial direction relative to the heating body 13, so that the surface of the heating body 13 may be cleaned in a reciprocating manner, which is more beneficial to cleaning the aerosol generating device 10. For example, under the action of the elastic part 70, the switch unit 30 is controlled to move in the third sliding groove 43 in a reciprocating manner, thus realizing the reciprocating cleaning of the surface of the heating body 13.

[0062] Referring to Fig. 10, an embodiment of the present invention further provides an aerosol generating system 1, comprising: the aerosol generating device 10 of any one of the foregoing embodiments; and an aerosol forming substrate 20 being placed in the containing part 12. After the aerosol forming substrate 20 is taken out from the containing part 12, the base 14 is capable of moving 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 is capable of preventing 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.

Those skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present invention. Accordingly, all equivalent modifications or changes made by those with general knowledge in the technical art without departing from the spirit and technical idea disclosed herein are to be embraced by the claims of the present invention.
