The strip-shaped protrusions 34 can not only effectively prevent the smoke particles from entering the cotton tube, but also have a certain transitional effect on the temperature generated by the combustion of the smoke particles after the partition 31 is set, so that the temperature is not transmitted to the The cotton tube section (the position where the user smokes in the mouth), thus realizing the cooling effect, and due to the set through hole 311 and the strip-shaped protrusion 34, the smoke generated by the combustion of the smoke particles can be released from the cotton tube section smoothly, so it is not It will not affect the release of smoke, thus making the user's experience better.

In some embodiments, the partition is provided with five through holes connecting the first smoke passage and the second smoke passage, one of the five through holes is located at the center of the partition, and the other four through holes surround The through-holes in the center are arranged in a circular array. Setting multiple through holes is more conducive to the fluency of smoke.

In some embodiments, a flow guide baffle is added to the outside of the through hole (that is, in the first smoke channel or the second smoke channel). Fixed, the flow guide baffle is located directly above the through hole, and the cross-sectional area of the flow guide baffle is larger than the cross-sectional area of the through hole, preferably, the flow guide baffle is in a circular shape. The gaps between adjacent support columns are for the passage of smoke from the through holes. The set guide baffle can change the path of smoke circulation, so as to further reduce the temperature.

Further, please refer to Figures 5 and 6, the sealing piece includes a sealing round paper 5 that is easily punctured by a heating needle; the sealing round paper 5 is provided with a plurality of microholes 51, and the plurality of microholes 51 are arranged neatly or randomly.

The diameter of the sealing circular paper 5 is 0.8cm-1.2cm, and the air permeability of the sealing circular paper 5 is 1000-5000CU.

Specifically, a plurality of micropores 51 are provided to increase the air permeability, so that when the heating is aimed at the smoking particles, the external air enters into the cigarette, which is helpful for the generation of the smoke of the smoking particles.

Further, please refer to FIG. 6 , the sealing circular paper sheet 5 includes a first layer; the first layer is a tipping paper layer 53 ; the thickness of the tipping paper layer 53 is 0.3mm-0.5mm. The tensile strength of the tipping paper layer 53 is 1.3-1.8/g.cm ^-3 . The sealing round paper sheet 5 also includes a second layer; the second layer is positioned on the inside of the tipping paper layer 53, the second layer is a high air permeability molding paper layer 52, and the thickness of the high air permeability molding paper layer 52 is 0.2mm- 0.6mm. The high air permeability forming paper layer 52 is made of one or a mixture of hardwood sulfite pulp, hardwood kraft pulp, softwood sulfite pulp and softwood kraft pulp.

In some embodiments, the integrated heat-not-burn cigarette further includes a cooling section, which is located between the smoking section and the empty pipe section, and is used for further cooling of the integrated heat-not-burn cigarette. The cooling section includes a cooling container and cooling granules installed in the cooling container (of course, the cooling granules can also be replaced by cooling powder); The smoke hole is arranged along the length direction of the cooling container, and the cooling container is also provided with a plurality of cooling chambers, the cooling chambers are arranged along the length direction of the cooling container, and the inner wall of the cooling chamber is provided with material holes for holding cooling particles.

In addition to setting the central hole in the center of the cooling container, multiple cooling channels are also provided, and the cooling channels are arranged along the length direction of the cooling container, and the inner wall of the cooling channel is provided with material holes for holding cooling particles. During use, when the flue gas passes through the cooling chamber, the cooling particles will continuously cool the flue gas, and the cooling effect is remarkable.

Preferably, the aperture of the smoke passage hole is larger than the aperture of the cooling channel.

Since the length of the heat-not-burn cigarette is generally constant, the particle size of the cooling particles is not too large or too small. Therefore, preferably, the particle size of the cooling particles is 0.8-1.2mm.

Preferably, the filling rate of the cooling particles in the material hole of the cooling channel is 60%-%75. The reason why the filled cooling particles should not be too much or too little is that choosing an appropriate filling rate can ensure that the heat-not-burn cigarette can stir the cooling particles with the swing of the human arm during use, so that it can Preventing the local temperature of some cooling particles from being too high is conducive to maintaining the uniformity of heat absorbed by each cooling particle and improving the cooling effect. Preferably, the cooling particles are made of polypropylene cooling masterbatch particles or ammonium carbonate particles.

Further, the outer surface of the cooling container is recessed with multiple arc-shaped grooves, the multiple arc-shaped grooves are arranged along the length direction of the cooling container, and the aroma-increasing sticks are arranged in the multiple arc-shaped grooves. The aroma-increasing rod is connected in the arc-shaped groove through an interference fit. The flavoring stick includes wrapping paper and spices encapsulated in the wrapping paper. Specifically, the spices can be spices with mint, coffee, fruity, and flowery flavors, and the packaging paper is made of heat-absorbing paper. Flavoring sticks can provide fragrance to heat-not-burn cigarettes, and the wrapping paper used is made of heat-absorbing paper, which can absorb part of the heat. Aroma emission has an auxiliary effect, and the aroma can be emitted faster and more intensely due to the heat. In order to further improve the cooling effect, the cooling container is made of polypropylene.
