Aerosol generating product with sectional aerosol generating substrate rod

Abstract

The invention discloses an aerosol generating product with a sectional aerosol generating substrate rod, which is characterized by comprising a smoke generating core material section (1), a breathable hollow section (2) and a filter section (3), the smoke generating core material section (1) comprises a sectional type aerosol generating matrix rod and anti-seepage/heat-conducting cigarette paper wrapping the sectional type aerosol generating matrix rod, the two ends of the sectional type aerosol generating matrix rod are short rod sections (11) formed by bonding sizing tobacco particles, and the middle of the sectional type aerosol generating matrix rod is a scattered particle section (12) formed by non-sizing tobacco particles; 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). The short rod sections (11) at the two ends can ensure that tobacco particles which are not bonded in the middle do not fall off and scatter, no adhesive exists on the surfaces and in gaps of the tobacco particles which are not bonded in the middle, and the axial ventilation capacity, porosity and smoke release amount of the aerosol generation matrix rod are ensured. The cigarette core with high porosity not only can increase the smoke amount, but also can simplify the structure of an aerosol generating product.

Description

technical field [0001] The invention relates to the technical field of heat-not-burn cigarettes, in particular to an aerosol generating product with segmented aerosol generating matrix rods. 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 to be sealed Paper and b...

Problems solved by technology

The problems that exist in the aerosol-generating matrix rod prepared by this method are: 1. Since a large amount of adhesive has been added in the stirring process, after cooling, the aerosol-generating matrix rod is also in the gap between adjacent tobacco particles. There is an adhesive after cooling, 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 adhesive directly during the mixing process , it will lead to uneven dispersion of the adhesive, 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 a large amount of Adhesives also lead to the application of a large amount of adhesive on the surface of each tobacco particle, which seriously affects the release of aerosols after the tobacco particles are heated. In fact, the purpose of sizing is only to bind the scattered tobacco particles , but it is not desirable that the non-bonded parts of the tobacco particles are also sizing, which affects the aerosol release
