Fig. 11 shows a second embodiment of the aerosol generating device according to the invention, which differs from the first embodiment in that the through hole 115 is arranged close to the first opening 112 at a distance from the first opening 112 which is smaller than or equal to the distance from the support wall 114, such that the distance from the through hole 115 to the second inlet channel 22 in the support wall 114 increases, which in turn leads to an increased removal of heat from the outer surface of the stationary tube.
Fig. 12 shows a third embodiment of the aerosol-generating device of the present invention, which is different from the first embodiment in that the cross-section of the fixing tube 11 may be oval, the insertion passage 1110 formed inside the tubular body 111 may be oval, and the stopper rib 1171 may be omitted. The length of the short axis of the insertion channel 1110 may be approximately equal to the outer diameter of the aerosol-forming substrate 200 so as to fix the aerosol-forming substrate 200, the length of the long axis of the insertion channel 1110 may be greater than the outer diameter of the aerosol-forming substrate 200, and the first air inlet channel 21 may be disposed at both ends of the long axis of the insertion channel 1110.
