Thus, the thermal airflow is more concentrated at the periphery of the cigarette 600, and nicotine delivery is further delayed.
  • the top block 724 is designed as a circular arc and protrudes towards the cigarette 600, i. e. the center the top block 724 faces away from the cigarette 600.
  • the top block 724 is of an axisymmetric structure, and the center of the top block 724 is located on the central axis of the bottom plate 722, so that the thermal airflow is evenly applied to the entire periphery of the cigarette 600.
  • the arc-shaped top block 724 also avoids completely sealing the bottom of the cigarette 600.
  • the thermal airflow passing through the air outlet hole 721 may also be diffused to the middle area, and the thermal airflow may slowly heat the central part of the cigarette 600 to achieve a pre-heating effect.
  • Fig. 12 is a top view of the air heat exchange and guide device provided in the fourth embodiment of the present application.
  • An edge of the top block 724 may be tangent to an edge of the air outlet hole 721, and the edge of the air outlet hole 721 is tangent to an inner edge of the fixing ring 723, thereby making full use of the guide member and preventing the thermal airflow from gathering at a boundary between the fixing ring 723 and the bottom plate 722.
  • Fig. 13 is a bottom view of the air heat exchange and guide device provided in the fourth embodiment of the present application.
  • the multiple air inlet holes 711 in the heat exchange core 710 are distributed in an array around the central axis of the heat exchange core 710.
  • the air inlet hole 711 is isolated from the support 730, as such, the thermal airflow can be prevented from being accumulated due to the holes in the heat exchange core 710 at the bottom of the support and cannot act on the cigarette 600 and causing waste of the thermal airflow.
  • the radius of the support 730 does not exceed one third of the radius of the heat exchange core 710, which prevents the cross-sectional area of the support 730 from being too large and the arrangement area of the air inlet holes 711 and the air outlet holes 721 being reduced.
  • heat transfer of the heat exchange core 710 can be reduced by reducing the volume of the support 730, so as to prevent nicotine in the cigarette 600 from being delivered quickly once the top block 724 is attached to the cigarette 600.
  • the support 730 When the central area of the cigarette 600 is heated, the support 730 is annular and located in the edge area of the air heat exchange and guide device 700, and the central axis of the support 730 coincides with the central axis of the air heat exchange and guide device 700.
  • the air outlet hole 721 is disposed in a middle area of the guide member 720 and is isolated from the support 730.
  • the thermal airflow can be gathered in the central area of the guide member 720 through the air outlet hole 721, so that the aerosol generating device 20 quickly delivers nicotine in the central area of the cigarette 600 first, and then delivers nicotine around the periphery of the cigarette 600, as such, nicotine is delivered gradually, and the balance of smoke generating can be improved.
  • Fig. 14 is an exploded view of an aerosol generating device 30 provided in a fifth embodiment of the present application.
  • the aerosol generating device 30 includes a heat generating pipe 800, a heat exchange core 900, and a guide member 1000.
  • the heat generating pipe 800 is used for placing a cigarette 1100.
  • the heat exchange core 900 is provided with multiple air inlet holes 910, and the air inlet holes 910 are in communication with the outside.
  • the heat exchange core 900 heats the gas entering the air inlet holes 910 from the outside.
  • the heat exchange core 900 is connected to the heat generating pipe 800, the heat generating pipe 800 generates heat and transfers the heat to the heat exchange core 900, so that the heat exchange core 900 generates heat.
  • the guide member 1000 is provided with an air inlet channel 1001 and an air outlet hole 1002.
  • the air inlet channel 1001 is in communication with the outside, and guides an external airflow to a first area of the cigarette 1100.
  • the air outlet hole 1002 is in communication with the air inlet hole 910 of the heat exchange core 900, and guides the airflow heated by the heat exchange core 900 to a second area of the cigarette 1100, where the first area and the second area do not overlap, and both the first area and the second area are local areas of the cigarette 1100.
  • the heat exchange core 1300 and the guide component 1400 are designed as separate structures, so that it is more convenient to install, and it is easier to replace the guide component 1400 as needed, so that more combination forms can be obtained for the heat exchange core 1300 and the guide component 1400.
  • the air inlet hole 1301 has a relatively small aperture and a relatively large number, which is beneficial to improving the balance of air intake and improving the thermal conductivity effect of air intake, so that the airflow can be heated quickly after entering the air inlet holes 1301.
