[0050] The following is an explanation of the embodiments of the present invention by specific specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this embodiment. On the contrary, the purpose of introducing the invention in conjunction with the embodiment is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will contain many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0051] refer to Figures 1 to 4 The present invention provides an aerosol generating device 10, comprising: a heating body 13 and a cigarette cartridge 11, wherein the cigarette cartridge 11 has a receiving portion 12, the heating body 13 is inserted into the receiving portion 12, and the heating body 13 is used to heat the aerosol-forming substrate 20 placed in the receiving portion 12. In addition, the aerosol generating device 10 also includes a base 14, which is located in the receiving portion 12 and is arranged around the heating body 13. Figure 1 and Figure 3 After the aerosol-forming substrate 20 is placed in the accommodating portion 12, the aerosol-forming substrate 20 is also placed on the base 14. At this time, the aerosol-forming substrate 20 placed in the accommodating portion 12 can prevent the base 14 from axially moving relative to the heating body 13. The base 14 remains stationary relative to the heating body 13 and does not affect the heating of the aerosol-forming substrate 20 by the heating body 13, so that the generated aerosol can be inhaled by the user, which is convenient for the user to use.

[0052] refer to Figure 2 and Figure 4 After the user finishes inhaling, the aerosol forming substrate 20 is taken out from the accommodating portion 12, and the base 14 can be moved axially ( Figure 4 (shown in the X direction). Figure 5 The base 14 is axially relative to the heating body 13 ( Figure 5 The base 14 can be lifted by the movement of the base 14 (as shown in the X direction), and foreign matter remaining on the base 14, such as dust, aerosol-forming matrix residue, etc., is also lifted, which facilitates cleaning of the base 14, that is, facilitates cleaning of the aerosol-generating device 10.

[0053] In this embodiment, the aerosol generating device 10 includes a switch unit 30. When the switch unit 30 is in an on state, the base 14 can move along the axial direction relative to the heating body 13. When the switch unit 30 is in an off state, the base 14 remains stationary relative to the heating body 13.

[0054] Specifically, refer to Figure 2 and Figure 4 The aerosol generating device 10 further includes a sliding cover 40, which is arranged on the cigarette bin 11 and has a through hole 45 corresponding to the receiving portion 12. The aerosol forming substrate 20 is inserted through the through hole 45 on the sliding cover 40 to be placed in the receiving portion 12 of the cigarette bin 11. Figure 5 As shown, the base 14 is provided in the sliding cover 40 and is axially ( Figure 5 The aerosol-forming substrate 20 is inserted through the through hole 45 on the sliding cover 40 to be placed on the base 14 in the accommodating portion 12 of the cigarette cartridge 11.

[0055] In this embodiment, reference Figure 4 The switch unit 30 is provided on the slide cover 40. When the switch unit 30 is in the open state, the switch unit 30 covers the through hole 45 (eg Figure 4 As shown), and can be separated from the cigarette bin 11 in the axial direction, the sliding cover 40 can be separated from the cigarette bin 11 in the axial direction (as shown Figure 5 When the switch unit 30 is in the closed state, the switch unit 30 and the through hole 45 are radially ( Figure 2 The sliding cover 40 is arranged in the Y direction, and the sliding cover 40 is engaged with the cigarette holder 11. The axial movement of the sliding cover 40 is restricted, wherein the radial direction is perpendicular to the axial direction. In this embodiment, when the switch unit 30 is in the closed state, the switch unit 30 and the through hole 45 are arranged in the radial direction (as shown in FIG. Figure 2 and Figure 3 As shown), in other embodiments, the switch unit and the through hole are radially adjacent, for example, radially contacting, and the projection of the two in the axial direction can be a line or an area, for example, the area is elliptical.

[0056] refer to Figure 6 and Figure 7 Combined with Figure 2 、 Figure 17 and Figure 18 As shown, in this embodiment, the sliding cover 40 is further provided with a through hole 45 along the radial direction ( Figure 6 The first slide groove 41 is provided (shown in the Y direction). In this embodiment, the first slide groove 41 and the through hole 45 are radially spaced apart. In other embodiments, the first slide groove and the through hole are radially adjacent, for example, radially contacting, and the projections of the two in the axial direction can be a line. The switch unit 30 is inserted into the first slide groove 41, and the switch unit 30 can slide along the first slide groove 41 to cover the through hole 45, as shown in FIG. Figure 4 As shown, Figure 4 The C direction is the movement direction of the switch unit 30, or the switch unit 30 can slide along the first sliding groove 41 to the position radially arranged with the through hole 45 (such as Figure 2As shown), for example, they are arranged at intervals in the radial direction, or are adjacent in the radial direction, for example, they are in contact in the radial direction, and their projections in the axial direction can be a line.

[0057] Continue to refer Figure 7 Combined with Figure 4 As shown, the switch unit 30 has an operating portion 31 and a clamping portion 32 along the axial direction. The operating portion 31 is located outside the sliding cover 40, and the clamping portion 32 is located inside the sliding cover 40. By controlling the operating portion 31, the switch unit 30 can be slid along the first sliding groove 41 to cover the through hole 45, so that the switch unit 30 is in the open state; or, by controlling the operating portion 31, the switch unit 30 can be slid along the first sliding groove 41 to be radially arranged with respect to the through hole 45, for example, radially spaced apart, so that the switch unit 30 is in the closed state. Figure 8 and Figure 18 The portion of the cigarette bin 11 facing the sliding cover 40 is provided with a second sliding groove 42, along the extension direction of the second sliding groove 42 ( Figure 8 The second chute 42 has a first portion 42b and a second portion 42a, wherein the extension direction of the second chute 42 is consistent with the extension direction of the first chute 41.

[0058] When the switch unit 30 is in the on state, the operating portion 31 covers the through hole 45 on the sliding cover 40, the clamping portion 32 is located in the first part 42b of the second sliding groove 42, and the clamping portion 32 can be separated from the first part 42b along the axial direction. Then, the axial movement of the sliding cover 40 is not restricted, the sliding cover 40 can be separated from the cigarette bin 11 along the axial direction, and the user can clean the base 14 inside the sliding cover 40.

[0059] When the switch unit 30 is in the closed state, the operating portion 31 and the through hole 45 are radially arranged, and the engaging portion 32 is located in the second portion 42a and axially engaged with the second portion 42a. The axial movement of the sliding cover 40 is restricted, and the sliding cover 40 cannot be axially separated from the cigarette holder 11. In this embodiment, when the switch unit 30 is in the closed state, the operating portion 31 and the through hole 45 are radially spaced apart. In other embodiments, the operating portion and the through hole are radially adjacent, for example, radially contacting, and their axial projection can be a line or an area, for example, an elliptical area.

[0060] When the switch unit 30 is in the closed state, the aerosol-forming substrate 20 can be inserted through the through-hole 45 on the sliding cover 40 and placed in the receiving portion 12 of the cigarette cartridge 11. The heating element 13 heats the aerosol-forming substrate 20 to generate aerosol for the user to inhale. During the inhalation process, the aerosol-forming substrate 20 and the operating portion 31 abut against each other in the radial direction. The aerosol-forming substrate 20 prevents the operating portion 31 from moving toward the through-hole 45 on the sliding cover 40. The switch unit 30 cannot be switched from the closed state to the open state, thereby not affecting the aerosol-generating device 10's atomization process of the aerosol-forming substrate 20, so that the normal use of the aerosol-generating device 10 is not disturbed. In other embodiments, during the inhalation process, the aerosol-forming substrate and the operating portion are arranged radially, but may not abut against each other, for example, they are arranged radially at intervals.

[0061] refer to Figure 8 In this embodiment, the width of the first portion 42b is wider than the width of the engaging portion 32, while the width of the second portion 42a is narrower than the width of the engaging portion 32. The switch unit 30 switches from the open state to the closed state by sliding from the first portion 42b to the second portion 42a. The engaging portion 32 can move up and down axially through the first portion 42b, but cannot move up and down axially through the second portion 42a.

[0062] In this embodiment, the first part 42b and the second part 42a respectively have two axially symmetrical areas, and the clamping portion 32 can be located in the two areas of the first part 42b and the two areas of the second part 42a respectively. This arrangement can improve the stability of the clamping portion 32 sliding along the second sliding groove 42.

[0063] refer to Figure 4 and Figure 9 Combined with Figure 18 As shown, in this embodiment, the sliding cover 40 is further provided with a deformable portion 60 that mates with the switch unit 30. The deformable portion 60 applies resistance to the switch unit 30 during the switching process between the open and closed states. In other words, the switch unit 30 experiences resistance as it slides along the first sliding groove 41. This resistance prevents the switch unit 30 from switching between the closed and open states without external forces, thereby improving the connection stability between the switch unit 30 and the sliding cover 40. Furthermore, the resistance applied by the deformable portion 60 must be overcome when the switch unit 30 switches from the open state to the closed state, and vice versa. This enhances the user's sense of control and serves to inform the user that the switch unit 30 has switched from the open state to the closed state, or vice versa.

[0064] refer to Figure 9In this embodiment, the operating portion 31 and the clamping portion 32 of the switch unit 30 are connected by the connecting portion 33. The connecting portion 33 can slide along the first sliding groove 41. The deformable portion 60 fits with the connecting portion 33 of the switch unit 30. Figure 9 ), the deformable portion 60 includes a first region 61, a second region 62, and a third region 63. In the on state, the first region 61 is in contact with the switch unit 30, and in the off state, the third region 63 is in contact with the switch unit 30. The width of the second region 62 is smaller than the width of the first region 61 and the width of the third region 63, respectively.

[0065] Then, the switch unit 30 will pass through the second area 62 during the switching process between the first area 61 and the third area 63. Since 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, the switch unit 30 will be squeezed, and the deformation portion 60 will apply resistance to the switch unit 30. After overcoming the resistance of the second area 62, the deformation portion 60 moves to the first area 61 or the third area 63.

[0066] It should be noted that the specific structure of the deformation portion is not limited thereto, and may also be other structural forms that can apply resistance to the switch unit.

[0067] In this embodiment, the deformable portion 60 is made of elastic material, and is disposed in the first sliding groove 41. When the switch unit 30 slides along the first sliding groove 41, it will experience resistance from the deformable portion 60.

[0068] refer to Figure 4 and Figure 5 In this embodiment, the base 14 is suspended in the sliding cover 40, which is convenient for cleaning the base 14 after the base 14 is separated from the heating body 13 along the axial direction. The connection method between the base 14 and the sliding cover 40 of the present invention is not limited. In this embodiment, the base 14 is connected to the through hole 45 through the axial extension portion 44, and the axial extension portion is used to accommodate the aerosol forming substrate 20. The axial extension portion 44 is radially spaced from the inner wall of the sliding cover 40, so that when the sliding cover 40 is covered on the cigarette bin 11, the base 14 and the axial extension portion 44 are located in the accommodating portion 12 of the cigarette bin 11. Figure 6 As shown, in this embodiment, part of the base 14 is connected to the axial extension portion 44. It can be understood that the axial extension portion 44 extends along the circumferential portion, and the base 14 and the axial extension portion 44 are L-shaped as a whole (such as Figure 5 After the base 14 is separated from the heating body 13 in the axial direction, a larger area is exposed, which is convenient for the user to clean the base 14.

[0069] refer to Figure 10 and Figure 11In other embodiments, the switch unit 30 is connected to the base 14, and part of the switch unit 30 is located outside the aerosol generating device 10, and is used to drive the base 14 relative to the heating body 13 in the axial direction ( Figure 10 and Figure 11 In this embodiment, the switch unit 30 can move in the axial direction toward the cigarette bin 11 ( Figure 10 The base 14 moves in the axial direction relative to the heating body 13.

[0070] Continue to refer Figure 11 In this embodiment, an elastic portion 70 is provided within the cigarette chamber 11. One end of the elastic portion 70 is connected to the base 14, and the other end is connected to the inner wall of the cigarette chamber 11. During the process of switching the switch unit 30 between the on and off states, the elastic portion 70 can apply resistance to the base 14. The presence of resistance prevents the switch unit 30 from arbitrarily switching between the off and on states when no external force is applied, thereby improving the stability of the connection between the switch unit 30 and the base 14. Furthermore, the switch unit 30 must overcome the resistance applied by the elastic portion 70 when switching from the on state to the off state, and the switch unit 30 must also overcome the resistance applied by the elastic portion 70 when switching from the off state to the on state. This enhances the user's sense of control and serves to prompt the user that the switch unit 30 has switched from the on state to the off state, or vice versa.

[0071] The relative position of the elastic portion 70 and the base 14 is not limited. In this embodiment, when the switch unit 30 drives the base 14 to move axially relative to the heating body 13, the elastic portion 70 can move radially ( Figure 11 In other embodiments, when the switch unit 30 drives the base 14 to move axially relative to the heating body 13, the elastic portion 70 may move axially.

[0072] Specifically, refer to Figure 11 The elastic part 70 includes a first axial extension part 50 and an elastic member 51. The extension direction of the first axial extension part 50 is consistent with the extension direction of the heating body 13. One end of the elastic member 51 is connected to the first axial extension part 50, and the other end is connected to the inner wall of the cigarette chamber 11. The base 14 has a second axial extension part 15. The first axial extension part 50 has an inclined surface. The second axial extension part 15 is against the inclined surface. The elastic member 51 and the second axial extension part 15 are located on different sides of the first axial extension part 50. The existence of the inclined surface enables the axial movement of the base 14 to be converted into the radial movement of the elastic part 70. In other embodiments, it can be other structural forms that can convert the axial movement of the base into the radial movement of the elastic part.

[0073] In this embodiment, the elastic member 51 is arranged along the radial direction ( Figure 11 In other embodiments, the elastic portion 70 may extend in other directions and may be compressed to facilitate radial movement of the elastic portion 70 and reset the elastic portion 70.

[0074] refer to Figure 12 The base 14 is provided with a third axial extension portion 16 on the side facing away from the second axial extension portion 15. The third axial extension portion 16 is connected to the switch unit 30. The extension direction of the third axial extension portion 16 is consistent with the extension direction of the heating body 13. In addition, the aerosol generating device 10 also includes a main body 101. Figure 10 A third slide groove 43 is provided on the main body 101, and the third slide groove 43 extends axially. The switch unit 30 is inserted into the third slide groove 43, and the switch unit 30 can slide along the third slide groove 43 to switch between the open state and the closed state.

[0075] In addition, the aerosol generating device 10 also includes an annular portion 52, which is provided on the elastic portion 70. When the switch unit 30 is in the open state, the annular portion 52 is at least partially located outside the accommodating portion 12 in the radial direction; when the switch unit 30 is in the closed state, the annular portion 52 is located in the accommodating portion 12, for inserting and accommodating the aerosol forming substrate 20 in the accommodating portion 12.

[0076] Specifically, refer to Figure 11 After the aerosol-forming substrate 20 is inserted into the accommodating portion 12 along the annular portion 52, the annular portion 52 is fitted onto the aerosol-forming substrate 20. The aerosol-forming substrate 20 prevents the elastic portion 70 from moving in the radial direction, thereby preventing the switch unit 30 from switching between the off and on states. This does not affect the aerosol-generating device 10's atomization process of the aerosol-forming substrate 20, ensuring that the aerosol-generating device 10 operates normally. At this point, the base 14 remains stationary relative to the heater 13, and does not affect the heater 13's heating of the aerosol-forming substrate 20, thereby allowing the generated aerosol to be inhaled by the user.

[0077] After the user has finished puffing, refer to Figure 13 After the aerosol-forming substrate 20 is taken out of the housing 12, the radial movement of the annular portion 52 is not restricted, so that the elastic portion 70 can move radially, and then the base 14 can move axially relative to the heating body 13 ( Figure 13 (shown in the X direction). Figure 13 and Figure 14 , the control switch unit 30 is axially moved in the third sliding groove 43 in the direction toward the cigarette bin 11 ( Figure 13 and Figure 14 The switch unit 30 is switched from the closed state to the open state. Figure 15 and Figure 16The third axial extension portion 16 moves axially, and then the base 14 moves axially relative to the heating body 13. The base 14 is lifted, and under the action of the inclined surface, the elastic portion 70 moves radially, and the elastic member 51 is compressed to generate elastic force.

[0078] Release the switch unit 30, and under the action of the elastic force, the elastic part 70 returns to its original position. Figure 16 The direction of C in the middle moves in the opposite direction, and then drives the base 14 to move axially toward the switch unit 30 ( Figure 13 The switch unit 30 is switched from the on state to the off state.

[0079] In other embodiments, the annular portion 52 may not be provided. After the aerosol-forming substrate 20 is inserted into the accommodating portion 12 and the user completes the inhalation, the aerosol-forming substrate 20 can be moved circumferentially relative to the heating element 13 for a period of time to release the aerosol-forming substrate 20 from the heating element 13. The switch unit 30 is then controlled to slide axially within the third chute 43 toward the cigarette cartridge 11. The lifting of the base 14 simultaneously lifts the aerosol-forming substrate 20, allowing the aerosol-forming substrate 20 to be extracted.

[0080] Preferably, the base 14 in the aerosol generating device 10 of the present invention is at least partially in contact with the outer peripheral surface of the heating body 13. In this embodiment, the base 14 is completely in contact with the outer peripheral surface of the heating body 13. After the aerosol-forming substrate 20 is taken out of the accommodating portion 12, since the base 14 is in contact with the outer peripheral surface of the heating body 13, the surface of the heating body 13 can be cleaned during the axial movement of the base 14 relative to the heating body 13. The base 14 reciprocates up and down axially relative to the heating body 13, and can reciprocately clean the surface of the heating body 13, which is more conducive to cleaning the aerosol generating device 10. For example, under the action of the elastic portion 70, the control switch unit 30 reciprocates in the third slide groove 43 to achieve reciprocating cleaning of the surface of the heating body 13.

[0081] refer to Figure 10 An embodiment of the present invention further provides an aerosol generating system 1, comprising: the aerosol generating device 10 according to any of the above embodiments; an aerosol-forming substrate 20, which is used to be placed in the accommodating portion 12; after the aerosol-forming substrate 20 is taken out of the accommodating portion 12, the base 14 can move axially relative to the heating body 13; after the aerosol-forming substrate 20 is placed in the accommodating portion 12, the aerosol-forming substrate 20 placed in the accommodating portion 12 can prevent the base 14 from moving axially relative to the heating body 13, and the base 14 remains stationary relative to the heating body 13.

[0082] In summary, the above embodiments provided by the present invention are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
