First embodiment

An exemplary embodiment of the aerosol passage element is shown in fig. 1. The aerosol passage element comprises a passage tube 5 open at both ends, and a partition 6 is provided in the passage tube 5. The peripheral edge portion of the separator 6 extends in the radial direction of the channel tube 5, and the peripheral edge portion thereof is fixedly connected to the inner wall of the channel tube 5. The partition 6 may form a support for the channel pipe 5, increasing the deformation resistance of the channel pipe 5. The partition plate 6 is provided with a plurality of through holes 9 extending along the axial direction of the channel pipe 5, and the fluid entering the channel pipe 5 can pass through the partition plate 6 through the through holes 9 on the partition plate 6 so as to flow from one end of the channel pipe 5 to the other end.

Further, since the flue gas aerosol entering the channel tube 5 needs to pass through the through holes 9 formed in the partition plate 6 to flow towards the rear end of the channel tube 5, the flow area of the aerosol flow provided by the through holes 9 in the partition plate 6 is obviously smaller than the cross-sectional area of the channel tube 5, the flow speed of the aerosol is increased when the aerosol passes through the through holes 9 according to the venturi effect, the pressure is reduced, and the temperature of the aerosol is reduced at the same time, so that the partition plate 6 provided with a plurality of through holes 9 in the channel tube 5 can reduce the temperature of the aerosol better, and provide better suction feeling.

Because the aerosol in the cigarettes can only continuously diffuse to the rear part of the channel tube 5 through the through holes 9 on the partition plate 6, the aerosol can flow to the rear end of the channel tube 5 through the through holes 9 in a concentrated manner in the flowing process, the aerosol passing through the through holes 9 is more concentrated and uniform, the fragrance of the aerosol is dispersed more uniformly, and the smoking feeling of the cigarettes is further improved.

The through hole 9 may be of any other geometry. In this embodiment, the through hole 9 is a circular hole.

Alternatively, in the first embodiment shown in fig. 2, 3 to 24 through holes 9 are provided in the partition 6.

Optionally, the ratio of the length to the diameter of the channel tube 5 is greater than 1.1, where the diameter value of the channel tube 5 is adapted to the diameter of the cigarette, that is, the outer diameter of the channel tube 5 is not greater than the inner diameter of the cigarette, so that the ratio of the length to the diameter of the channel tube 5 is set to be greater than 1.1, so that the channel tube 5 has a sufficient length, and the flue gas aerosol generated by the smoke generating section 2 remains in the channel tube 5 for a longer time, thereby obtaining a better cooling effect.

Optionally, the partition 6 is provided at the front of the channel tube 5. Specifically, the distance between the partition plate 6 and the front end of the channel pipe 5 is 1/10 to 1/2 of the total length of the channel pipe 5.

Further, considering that the whole volume of the aerosol channel element disclosed by the utility model is smaller, in order to improve the assembly efficiency of the aerosol channel element during cigarette production, the distance between the partition plate 6 and the front end of the channel tube 5 is 1/10-1/3 of the total length of the channel tube 5, and the partition plate 6 is arranged at the front part of the channel tube 5, so that the whole gravity center of the channel tube 5 can move towards the front end direction, the aerosol channel element can be screened in a vibration screening mode, the rapid screening of the channel tube 5 can be realized by using a vibration disc by using the gravity center shifting effect, the direction of the channel tube 5 after screening is consistent, and the assembly efficiency of the channel tube 5 is convenient to improve.

Alternatively, the front end peripheral edge portion of the channel tube 5 is configured as an arc surface to form a rounded end 7 while the rear end face of the channel tube 5 remains unchanged, so that the degree of recognition of the front end face and the rear end face of the channel tube 5 can be increased, and the problem of reverse mounting of the front end face and the rear end face of the channel tube 5 can be reduced

Optionally, the radius of the circular arc surface of the round end 7 is 0.2-0.8 mm.

Optionally, the rear end face periphery of the channel tube 5 is also configured as a rounded corner.

Alternatively, referring to fig. 2 to 4, since the diaphragm 6 is subjected to radial force, in order to enhance the deformation resistance of the diaphragm 6, the diaphragm 6 is allowed to withstand greater radial force, and a plurality of reinforcing ribs 8 are provided on the diaphragm 6. Specifically, the reinforcing ribs 8 protrude from the plate surface of the separator 6, and both ends of the reinforcing ribs 8 extend in the radial direction of the separator 6. These reinforcing ribs 8 are equiangularly distributed around the center of the partition 6.

Alternatively, the thickness of the wall of the channel pipe 5 is 0.4-1.0 mm. Too thin a wall of the channel tube 5 cannot ensure mechanical strength of the channel tube 5 and is easily damaged at the time of assembly. Too thick a tube wall would result in too small an inner diameter of the channel tube 5, which is detrimental to sufficient dispersion and cooling of the aerosol.

Alternatively, the material used for the aerosol passage element may be paper, plastic, glass, metal, ceramic, or the like.

The diameter, the number and the distribution of the through holes 9 on the partition plate 6 can be determined according to the pressure drop requirement of cigarettes. The shape of the through hole 9 can be selected according to the requirement, but the requirement of aerosol diffusion and circulation is met. In the present embodiment, 24 circular through holes 9 are provided in total on the partition plate 6, and since four reinforcing ribs 8 divide the surface of the partition plate 6 into four sector-shaped regions of the same size, six circular through holes 9 are provided in each sector-shaped region.

Alternatively, the shape of the through hole 9 may be other suitable shape than a circle, such as a hexagon, an ellipse, or the like.

Optionally, the aerosol channel element is further formed with a flavoring layer on the surface thereof by means of infiltration, coating and the like, when the aerosol formed by the cigarette passes through the channel tube 5, the flavor substances in the flavoring layer can be diffused into the aerosol, so that the smoke aerosol enters the oral cavity to remove the flavor, and meanwhile, the smoking feeling can be enriched, and the taste of the cigarette is improved.
