Description

Particulate aerosol-generating article without the use of a multi-ported fastener segment for plugging

Technical Field

The utility model belongs to the aerosol generates goods field, especially belongs to the aerosol that uses aerosol source material granule and generates goods technical field, and more specific limited one kind need not to use the granule type aerosol that many through-holes firmware section shutoff and generates goods.

Background

Particle-type aerosol-generating articles are a new type of Heat-Not-Burn (abbreviated as HNB) aerosol-generating articles in recent years, which use aerosol-source material particles as an aerosol-generating material instead of an aerosol-source material sheet, the aerosol-source material particles are heated more uniformly than the aerosol-source material sheet, and the aerosol spreads more smoothly along inter-particle gaps than along sheet-like material gaps, and thus are popular among consumers.

Particulate aerosol-generating articles are known products on the market, the structure of which is illustrated with reference to figure 1: the main structure of the device is an integrated outer sleeve 2, the far lip end of which is sealed by a breathable sealing component 1, then aerosol source material particles 6 are filled into the integrated outer sleeve to form a particle segment, a multi-hole fixing component (commonly called a gear component) 9 is arranged at the downstream of the particle segment, then a cavity segment 10 is reserved for collecting and containing aerosol (sometimes, the side wall of the cavity segment 10 is also provided with an air inlet hole for cooling the aerosol, or sometimes, the cavity segment is filled with a cooling material or a flavoring material for cooling or flavoring), and a filter segment 7 is arranged at the downstream of the cavity segment 10 and is used as a cigarette holder for holding in the mouth of a user. The aerosol-generating article is in use inserted with its distal lip end into a heating device having a central heating element which punctures the gas-permeable closure 1 and inserts into the interior of the particle segment to heat the particles to release the gaseous flavour ingredient which condenses in the cavity segment 10 on cooling air to form a macroscopic aerosol which then passes through the filter segment to be filtered into the mouth of the user.

The hollow cavity section 10 is crucial to aerosol formation, according to the theory of aerosol science, the gaseous flavor component released by heating needs to be cooled to be condensed into solid particles or liquid particles, and the solid particles or the liquid particles need to be suspended in the air to form aerosol (commonly called "smoke" or "fog" or "smoke" in general) visible to the naked eye, so in the existing particle type aerosol generating product, the hollow cavity section is required to be left.

Furthermore, because the particles are loose and fluid, if not confined, they inevitably flow on a large scale to the downstream cavity section when the aerosol-generating article is placed horizontally or inverted, resulting in a substantial reduction in the number of particles that can be directly heated by the inserted heating element, and naturally the amount of flavour released and subsequently generated aerosol will also be reduced, and to ensure that the particles are sufficiently heated, the particles must be confined to a limited space in the vicinity of the heating element. The restraint is realized by arranging the air-permeable sealing piece 1 at the upstream of the granule section and providing a multi-hole fixing piece section 20 at the downstream of the granule section at present, and the two ends restrain the granules from flowing everywhere.

Wherein the multi-porous anchoring element 9 is typically ceramic or silicone, and has an outer wall which is firmly attached to the inner wall of the paper sleeve by means of an adhesive, and has at least one axial through hole 91 in its center, and/or at least one peripheral vent groove 92 in its outer periphery, which are dimensioned to allow the passage of smoke but not the particles of the aerosol source material, thereby both blocking the particles of the aerosol source material and transmitting the smoke. In addition, when the resistance heating sheet or the electromagnetic heating sheet is inserted into the particle section for central heating, the multi-hole firmware section can be firmly adhered to the inner wall of the paper tube, so that aerosol source material particles can be prevented from pushing the multi-hole firmware section to move downstream under the pushing of a heating sheet insertion force (because the filled particles have great resistance to the insertion of the heating sheet, a user needs to provide an insertion force for the heating sheet to insert the heating sheet). However, the presence of the multi-aperture fastener segment adds cost and operational inconvenience to the commercial manufacture of particulate aerosol-generating articles and it is therefore a continuing desire of those skilled in the art to eliminate the multi-aperture fastener segment. However, after the multi-through-hole firmware section is eliminated, the problem of how to restrict the particles is difficult under the premise that a cavity section must exist at the downstream of the particle section.

The utility model aims to solve the problems.
