Definitions

  • the present invention relates to the technical field of aerosol-generating products, and in particular to an aerosol-generating product with a supporting section scented.
  • Existing aerosol-generating products mainly include a smoking core material section, a support section, a cooling section and a filter section.
  • the support section not only plays a supporting role in smoking products, but more importantly, it gathers smoke and assists the cooling section in protecting the smoke. The air cools down.
  • the existing technology uses online laser drilling to penetrate the pipe wall of the support section, and the molding paper and tipping paper wrapping the pipe wall form ventilation holes, allowing outside air to enter the inside of the support section and mix with the smoke, thereby increasing the amount of smoke and effectively reducing the Flue gas temperature, but its cooling effect on flue gas and mixing effect of air and flue gas are still not good. The reasons are the following two points: 1.
  • the radial support force of the pipe wall of the support section is insufficient, and the pipe wall is pushed backward by external force.
  • the center of the tube cavity collapses, causing the airflow channel of flue gas and air to be blocked and the amount of smoke to be insufficient;
  • the contact area between the flue gas and the support section pipe wall is limited, and effective cooling cannot be achieved;
  • the flue gas and air are in the support section
  • the residence time in the section is short, and the flue gas and air directly and quickly enter the cooling section through the support section, and full mixing cannot be achieved; 4.
  • the flue gas directly contacts the pipe wall of the support section, and because the flue gas passing through the support section has not been effectively cooled, the smoke The temperature is too high, causing the pipe wall in this section to become hot.
  • the current main focus is to improve the cooling materials in the cooling section or directly increase the amount of cooling materials.
  • most of the cooling materials are phase change materials. After a few puffs, the phase change materials shrink. It collapses and blocks the air flow channel, greatly increasing the suction resistance and affecting the suction experience.
  • existing aerosol-generating products are generally flavored through tobacco materials, filters, and cigarette papers.
  • the fragrance-carrying process is difficult, inefficient, and the flavor release is unstable.
  • Existing aerosol-generating products usually place flavored exploding beads in the filter, and consumers manually pinch the exploding beads before smoking, thereby releasing the aromatic substances inside them, thus replacing the gas during inhalation.
  • the sol has the aroma-enhancing effect, but the problem is that since the popping beads have been completely crushed before smoking, the aroma-enhancing substances inside are completely released. This results in a strong fragrance in the early stage of smoking, but in the subsequent smoking The aroma weakened significantly in the later period, and there was almost no aroma-enhancing effect.
  • the disadvantage of using tobacco materials or cigarette paper to carry fragrance is that due to the high volatility of many spices, these characteristic fragrances are easily lost after the user opens the package, resulting in poor quality of the cigarettes at the end of each pack that have no fragrance.

  • the smoke temperature when the aerosol-generating product sample 2 enters the smoker's mouth is 38.9°C.
  • the ventilation hole 31 of the present invention has the same shape and size as the hole drilled on the support section in the prior art, the ventilation hole 31 of the present invention is closer to the smoker's mouth, so The suction force at the ventilation hole 31 is significantly greater than the suction force at the hole drilled on the support section in the prior art.
  • the ventilation hole 31 of the present invention has a better ventilation effect and introduces a larger amount of ambient air, which is more conducive to reducing smoke. air temperature.
  • the cigarette support section 2 of the present invention has a cavity, and the breathable hollow section 3 has a cavity, so that the introduced air can better contact and mix with the smoke, further reducing the temperature of the smoke.
  • the aromatic channel 21 forms an air insulation layer.
  • sensory evaluators clearly feel that compared with existing aerosol-generating products, The outer surface temperature of the support section of the product of the invention is low, and there is no problem of burning hands at all.
  • the fragrance and aroma evaluation scores given by the sensory evaluators are basically consistent. There is no problem that the fragrance is strong in the early period of smoking and weak in the later period.

Abstract

Produit de génération d'aérosol comportant une section de support d'arôme. La section de support (2) possède un conduit d'écoulement d'air creux (22) et de multiples conduits d'arôme (21). Les multiples conduits d'arôme (21) entourent la face externe du conduit d'écoulement d'air creux (22). L'extrémité du côté du conduit d'arôme (21) proche de la section centrale du matériau à fumer (1) est obstruée, tandis que l'extrémité du côté proche de la section creuse perméable à l'air (3) est ouverte. Au moins une partie du conduit d'arôme (21) est pourvue d'une capsule d'arôme (11), et la capsule d'arôme (11) est proche du côté de la section centrale du matériau à fumer (1). La section creuse perméable à l'air (3) est pourvue d'un trou de ventilation (31) qui pénètre à travers la paroi de tube de la section creuse perméable à l'air (3) dans la direction radiale. Une bille placée à l'avant agit pour libérer automatiquement de l'arôme lorsque le produit de génération d'aérosol est utilisé, ce qui permet d'améliorer l'efficacité d'aromatisation et la stabilité de la libération d'arôme. Pendant ce temps, la section de support (2) se remplit à nouveau d'arôme, et de l'air est introduit dans la section creuse perméable à l'air (3). Ainsi, la résistance au tirage peut être réduite, le confort est amélioré, et la quantité de fumée et une température appropriée de la fumée sont en outre garanties.
