In this embodiment, the bottom bracket 14 is arc-shaped.

[0041] Further, a positioning platform 142 is provided on the first resisting surface 141, and the inner sides of the front inner shell 11a and the rear inner shell 11b are respectively provided with a positioning groove 113 for the positioning platform 142 to be inserted, so as to limit the position of the bottom bracket 14 and prevent it from shaking after being clamped.

[0042] Preferably, the front inner shell 11a and the rear inner shell 11b are fixed by a locking member / locking members. Further, in this embodiment, a number of locking holes 114 are provided on the rear inner shell 11b, and a number of connecting holes 115 corresponding to the locking holes 114 are provided on the front inner shell 11a, and the locking member passes through the connecting hole 115 to be locked with the locking hole 114 to lock the front inner shell 11a and the rear inner shell 11b, thereby improving the stability of the entire inner shell 11.

[0043] The heating device 20, the battery, the circuit assembly 30, the display assembly 40, and the bottom bracket 14 can be placed before the front inner shell 11a and the rear inner shell 11b are locked, and are locked in position after being locked. The head assembly 13 can be installed and snapped fitted to the head after the front inner shell 11a and the rear inner shell 11b are locked, and the installation method is convenient.

[0044] In this embodiment, the outer shell 12 includes a front outer shell 12a and a rear outer shell 12b, which are respectively covered outside the front inner shell 11a and the rear inner shell 11b, playing a role in decoration and protection.

[0045] Specifically, a side of the front inner shell 11a is provided with a number of first clamping platforms 116 in the circumferential direction, a side of the rear inner shell 11b is provided with a number of second clamping platforms 117 in the circumferential direction, and at least two third clamping platforms 1314 are respectively provided at the two ends of the head bracket 131.

The decorating member 15 is filled in the groove formed between the two sides of the front outer shell 12a and the rear outer shell 12b, and the outer surface of the decorating member 15 is integral with the outer surfaces of the front outer shell 12a and the rear outer shell 12b.

[0049] As shown in FIG. 3 and FIG. 9, in some embodiments, the heating device 20 includes a heating hole D for allowing the insertion of the aerosol forming substrate end 51 of the aerosol forming product 50, and a heating assembly 21 disposed outside the heating hole D. The insertion opening B, the guide opening C and the heating hole D form the insertion hole 22 for the insertion of the aerosol forming product 50. The heating hole D is corresponding to the insertion opening B, so that the aerosol forming substrate end 51 of the aerosol forming product 50 can be sequentially inserted into the insertion opening B, the guide opening C, and the heating hole D.

[0050] In this embodiment, the aerosol forming product 50 includes a vent tube 52 and a suction nozzle 53. The aerosol forming substrate end 51 and the suction nozzle 53 are respectively connected to the two ends of the vent tube 52, and a circulation hole 521 (as shown in FIG. 2) is provided on the side wall of the vent tube 52. Gas can enter the vent tube 52 through the circulation hole 521, and bring the aerosol formed by heating the aerosol forming substrate end 51 to the suction nozzle 53 away from the aerosol forming substrate end.

[0051] In this embodiment, the heating assembly 21 includes a heating tube 23 and a heating member 211 disposed on the outer ring of the heating tube 23. The heating tube 23 is cylindrical, and the inner hole of the heating tube 23 forms the heating hole D.

[0052] Preferably, in this embodiment, the inner end of the heating tube 23 away from the insertion opening B is closed, so that the heating tube wraps around the aerosol forming substrate end 51, and the aerosol forming substrate end 51 is wrapped and sealed, the sealing performance is better, and the problems such as a gap caused by assembly do not need to be considered.

[0053] When in use, the insertion opening B is used for the insertion of the aerosol forming product 50, and the heating hole D is used for the insertion of the aerosol forming substrate end 51 at the inner end of the aerosol forming product 50 inserted in the insertion opening B. After the aerosol forming product 50 is inserted in place, the inner ring of the heating hole D wraps the inserted aerosol forming substrate end 51 to achieve sealing, the heating member 211 of the heating assembly 21 is energized and emits thermal magnetic induction lines, causing the heating tube 23 of the heating assembly 21 to generate heat to heat the aerosol forming substrate end 51 in the heating hole D to generate aerosols.

[0054] Of course, in other embodiments, the heating assembly 21 may also eliminate the heating member 211 and use a resistance heating, and after the heating tube 23 is powered on, it generates heat to heat the aerosol forming substrate end 51 in the heating hole D to generate aerosols.

[0055] As shown in FIG. 9 and FIG. 10, in order to fix the inserted aerosol forming product 50 and ensure that the aerosol forming substrate end 51 can exchange air with the outside normally, a protruding structure 1315 is provided on the inner periphery of the insertion opening B to clamp and support the aerosol forming product 50. During and after the suction process of the aerosol forming product 50, the aerosol forming substrate end 51 is heated and consumed to shrink, the protruding structure 1315 can still fix the aerosol forming product 50, so that the aerosol forming product 50 will not be taken out by the mouth during the suction process.

[0056] Preferably, the protruding structure 1315 is in an interference fit with the aerosol forming product 50 inserted in the insertion opening B, which can clamp the aerosol forming product 50 to prevent it from being taken away by the mouth during the suction process.

[0057] Meanwhile, the space between the protruding structure 1315 and the inner wall of the insertion opening B forms a channel, so that air can enter the vent tube 52 through the circulation hole 521, and the aerosol produced by heating the aerosol forming substrate end 51 can be taken away when the user inhales.

[0058] Further, the protruding structure 1315 includes a plurality of protruding claws 1316 distributed along the circumferential direction of the inner ring of the insertion opening B to fix the middle section of the aerosol forming product 50. The protruding claws 1316 are used to clamp the aerosol forming product 50 at multiple points, which can achieve a clamping and fixing effect to improve the stability. Preferably, the end of the protruding claw 1316 is arc-shaped to fit the side surface of the aerosol forming product 50, and the protruding claws 1316 integrally form a semi-wrap around the aerosol forming product 50.

[0059] An arc-shaped ventilation hole 1317 is formed between two adjacent protruding claws 1316 in the circumferential direction, so that air can flow into the insertion opening B to enter the vent tube 52 through the circulation hole 521. Preferably, the protrusion height of the protruding claws 1316 are the same, so that the sizes of the ventilation holes 1317 in the circumferential direction are uniform, making the entry of the gas more uniform, and improving the stability of atomization.

[0060] Preferably, the protruding claw 1316 is provided with an oblique angle for guiding the insertion of the aerosol forming product 50, so that the direction control before the insertion is more accurate. Meanwhile, edges of the end of the protruding claw 1316 may be chamfered or rounded, to facilitate the insertion and the retrieval of the aerosol forming product 50, making the insertion and the retrieval smoother.

[0061] As shown in FIG. 3, FIG. 9, FIG. 12, FIG. 13, and FIG. 14, in some embodiments, the heating device 20 further includes a heating bracket 24 and a heating cover 25. The inner end of the heating tube 23 is in a sealing fit with the heating bracket 24. Further, in this embodiment, the heating bracket 24 includes a bottom support 241 matched with the inner end of the heating tube 23, and a heat insulation tube 242 sleeved outside the heating tube 23. In this embodiment, the bottom support 241 is in a cup-shaped structure and is sleeved onto the inner end of the heating tube 23. In other embodiments, the inner end of the heating tube 23 may not be closed, and the bottom support 241 is sleeved on the inner end of the heating tube 23 to achieve sealing with the heating tube 23, or to support and position other positions of the heating tube 23.

[0062] Preferably, the heating assembly 21 is located outside the heat insulation tube 242, so that the heat of the heating assembly 21 is not directly transferred to the aerosol forming substrate end 51 or the heating tube 23.

[0063] Further, the heating bracket 24 includes a support seat 243 disposed outside the bottom support 241 and located at the bottom of the heating device 20. The support seat 243 is a hollow structure. In this embodiment, the shell 10 clamps the support seat 243, so that the shell 10 and the heating assembly are spaced by the hollow support seat 243, thereby reducing the heat transferred from the heating assembly to the shell 10 and reducing energy loss.

[0064] Preferably, the support seat 243 includes a number of pillars 2431 and a connecting base 2432. The pillars 2431 are arranged at intervals in the circumferential direction of the bottom support 241 and extend away from the heating tube 23. The connecting base 2432 is connected to the outer end of each pillar 2431.

[0065] In this embodiment, the connecting base 2432 is annular and connected to the outer end of each pillar 2431, making the support seat 243 integrally form a frame structure. The heat of the heating assembly 21 is transferred from the frame structure to the shell 10, which can reduce the heat transfer and reduce power consumption.

[0066] Preferably, the outer periphery of the connecting base 2432 is provided with a flange 2433 that extends outward for positioning the heating bracket 24 after the shell 10 is engaged. In this embodiment, the display bracket 16 of the display assembly 40 is locked with the rear inner shell 11b, to clamp the flange 2433 for positioning. In other embodiments, the front inner shell 11a and the rear inner shell 11b may be locked to clamp the flange 2433 to position the heating bracket 24.

[0067] In addition, the heating cover 25 is sleeved on the outer end of the heating tube 23 facing the insertion opening B, and is in a sealing fit with the outer end of the heating tube 23. Since the heating cover 25 is in a sealing fit with the heat insulation tube 242, and the heat insulation tube 242 is connected to the outer ring of the bottom support 241, a sealed first isolation chamber E is formed between the heat insulation tube 242 and the heating tube 23, so that the heat of the heating assembly 21 can be prevented from being directly transferred to the heating tube 23, thereby reducing the atomization speed of the aerosol forming substrate end 51, and reducing the power consumption.

[0068] The outer ring of the heating cover 25 is provided with a sealing ring 251 for sealing the heating cover 25 and the heat insulation tube 242, which is used to ensure the sealing performance of the first isolation chamber E and the insulation effect.

[0069] Preferably, as shown in FIG. 9 and FIG. 14, in order to reduce the contact and heat conduction between the heating assembly 21 and the wall of the heat insulation tube 242, a number of convex ribs 2421 are provided on the outer wall of the heat insulation tube 242 at intervals in the circumferential direction, to form a second isolation chamber F between the heating assembly 21 and the heat insulation tube 242, further reducing the heat transmission speed of the heating assembly 21 to the heat insulation tube 242 and the heating tube 23, reducing the atomization speed of the aerosol forming substrate end 51, and reducing the power consumption.

[0070] Further, as shown in FIG. 9, FIG. 12, and FIG. 13, the inner periphery of the heating cover 25 is provided with a guiding surface 252 inclined towards the inside of the heating tube 23 to guide the insertion of the aerosol forming product 50, making the insertion of the aerosol forming product 50 smoother and avoiding jamming.

[0071] In order to reduce the contact between the heating cover 25 and the outside and reduce the speed of heat transfer to the outside, the inner bracket 132 further includes a sleeve tube 1322 that is in a sealing fit with the heating cover 25. The sleeve tube 1322 is sleeved on the outer ring of the heating cover 25, so that the heat of the heating cover 25 is transferred outwards through the sleeve tube 1322, thereby reducing energy loss.

[0072] In order to smoothly guide the aerosol forming product 50 into the inner ring of the heating cover 25 from the guide opening C, a guide tube 1323 is provided extending from the guide opening C towards the heating cover 25. Preferably, the guide tube 1323 and the heating cover 25 are spaced apart from each other to avoid direct heat transfer. Further, the guide tube 1323 is spaced apart from the sleeve tube 1322, so that the heat of the heating cover 25 can only be transferred outwards through the sleeve tube 1322, thereby reducing heat transfer.

[0073] Further, the outer ring of the end of the heating cover 25 matched with the sleeve tube 1322 is provided with a sealing ring 251 sealed with the sleeve tube 1322. The outer ring of the heating cover 25 is provided with a sealing groove for the sealing ring 251 to be disposed.

[0074] In order to further reduce the heat transfer from the heating cover 25 to the outside, the outer ring of the heating cover 25 is provided with a partition groove 253 in the circumferential direction. By adding the partition groove 253, the wall thickness of the heating cover 25 is reduced, and thereby the heat transfer amount is reduced. Preferably, the partition groove 253 is located between the sleeve tube 1322 and the heating tube 23, reducing the heat transfer to the sleeve tube 1322 and improving the heat utilization efficiency.

[0075] The heating member 211 is disposed outside the heat insulation tube 242. Preferably, the heating member 211 of the heating assembly 21 is arranged along the circumferential direction of the heating tube 23, so that the heating is more uniform. Further, the heating member 211 is symmetrically arranged around the central axis of the heating tube 23, so that the temperature inward and outward radiation is more uniform, the atomization of the aerosol forming substrate end 51 is more uniform, and the external temperature of the aerosol forming substrate end 51 is more uniform.

[0076] In this embodiment, the heating member 211 is a heating coil wound outside the heat insulation tube 242, which makes the temperature more uniform.
