The side wall of the flow guide pipe 504 is provided with a plurality of radially extending air guide holes 505, the rear end plate 507 is provided with air holes 508, aerosol entering the cooling section 500 can firstly spread and spread into a containing cavity defined by the flow guide pipe 504 and the inner wall of the cigarette tube due to the blocking of the front end plate 506, the heat of the aerosol can be quickly conducted to the outside of the cigarette tube through the wall of the cigarette tube, the aerosol can be quickly cooled, meanwhile, the outer periphery of the rear end plate 507 is attached to the inner wall of the cigarette tube, namely the aerosol entering the containing cavity can be blocked by the rear end plate 507, so that the aerosol cannot directly flow into the mouthpiece section 100, and can only flow into the cavity of the flow guide pipe 504 from the air holes 505, and then can enter the mouthpiece section 100 through the air holes 508 arranged on the rear end plate 507, so that the flow path of the aerosol can be effectively prolonged, and the cooling effect of the cooling section 500 can be further improved. In addition, it is also necessary to see that the front end plate 506 of the flow guide pipe 504 also restricts the flow of the aerosol, so that the flow cross section of the aerosol after entering the cooling section 500 is rapidly reduced, and thus the flow velocity of the aerosol in the cooling section 500 is increased, and the temperature is reduced along with the increase in the flow velocity, and the temperature of the aerosol is further reduced. Similarly, the air hole 505 formed in the duct 504 and the air hole 508 formed in the rear plate 507 reduce the flow cross section of the aerosol, and also have the effect of reducing the aerosol temperature.
The accommodating cavity defined by the flow guide pipe 504 and the inner wall of the cigarette tube is filled with microsphere particles 600, so that the aerosol entering the accommodating cavity is fully contacted with the microsphere particles 600 in the flowing process, on one hand, the flowing path of the aerosol is prolonged, the residence time of the aerosol in the accommodating cavity is prolonged, the cooling effect is improved, and on the other hand, the fragrance attached to the microsphere particles 600 can be diffused into the aerosol to perfume the aerosol.
In an exemplary embodiment, the cross-section of the draft tube 504 is projected as a polygon on a horizontal plane. As shown in fig. 3, the cross section of the draft tube 504 has a projection shape on the horizontal plane that is similar to the projection shape of the gear shape having six teeth on the horizontal plane.

In this embodiment, the cross section of the flow guiding pipe 504 is a circular pipe, as shown in fig. 7 to 8.
As shown in fig. 10, an inner sleeve 509 is further disposed inside the flow-guiding tube 504, and the outer diameter of the inner sleeve 509 is smaller than the inner diameter of the flow-guiding tube 504, in other words, there is a space between the wall of the inner sleeve 509 and the wall of the flow-guiding tube 504. The inner sleeve 509 is also provided with radial flow-through holes 510, from the aerosol entering the flow-guide tube 504 through the flow-through holes 510 in the inner sleeve 509 into the inner sleeve 509 and finally from the ventilation holes 508 in the rear end plate 507 into the mouthpiece section 100. The inner sleeve 509 can further limit the flow of aerosol and prolong the residence time of aerosol for better cooling effect.
