Aerosol generating product having granular aerosol-generating matrix rod with high porosity

Abstract

The invention discloses an aerosol generating product having a granular aerosol generating matrix rod with high porosity. The aerosol generating product comprises a smoke generating core material section (1), a breathable hollow section (2) and a filtering section (3), the smoke generating core material section (1) comprises an aerosol generating matrix rod and anti-seepage / heat-conducting cigarette paper wrapping the aerosol generating matrix rod, the aerosol generating matrix rod is formed by binding scattered tobacco particles through a binding agent, and the binding agent is arranged on part of the surfaces of only part of the tobacco particles in the aerosol generating matrix rod; the internal porosity of the smoke generating core material section (1) is 40-80%; the breathable hollow section (2) and the filter section (3) are wrapped by the forming paper (5) to form a filter rod, and the smoke generating core material section (1) and the filter rod are connected through the tipping paper (4). Before the scattered tobacco particles are bonded, the surfaces of all the tobacco particles are not provided with the binder, and the binder does not cover all the surfaces of the tobacco particles, so that the problem that gaps formed between the tobacco particles are blocked after the binder is cooled does not exist in the gaps formed between the tobacco particles after the tobacco particles are bonded; therefore, the axial ventilation capacity and porosity of the aerosol generation matrix rod are ensured.

Description

technical field [0001] The invention relates to the technical field of heat-not-burn cigarettes, in particular to an aerosol-generating product with a particle-type aerosol-generating matrix rod with high porosity. Background technique [0002] As consumers pay more attention to health issues and demand for personalized experience of cigarette products, the tobacco industry continues to respond to the upgrading of consumer demand and develops various smoking products with reduced tar and harm. Among them, heated cigarettes can provide a healthier smoking experience while satisfying consumers' sensory needs for cigarette products because their cigarette heating methods are different from traditional cigarette products. [0003] The smoking material of granular heating cigarettes is bulk smoking particles. In the prior art, since the bulk smoking particles cannot be fixed, they must be filled into the outer tube by filling, and both sides of the smoking particle section need t...

AI Technical Summary

Problems solved by technology

The problems in the aerosol-generating matrix rods prepared by this method are: 1. Since a large amount of binding agent has been added in the stirring process, after cooling, the aerosol-generating matrix rods in the gaps between adjacent tobacco particles also There is a cooled binder, which leads to low porosity of the aerosol-generating matrix rod and small axial air permeability; 2. If in order to avoid the first problem, add less binder directly during the mixing process , it will lead to uneven dispersion of the binder, and the tobacco particles without sizing on the surface are adjacent to each other, resulting in failure to bond and the problem of scattered smoke particles; 3. Another more critical problem is that adding a large amount of The binder also causes a large amount of binder to be applied on the surface of each tobacco particle, which seriously affects the release of aerosol after the tobacco particle is heated. In fact, the purpose of sizing is only to bind the scattered tobacco particles , but it is not desirable that the non-bonded areas of the tobacco particles are also sizing to affect the aerosol release
