Fragrance slow-release cooling unit and heating type aerosol generating product comprising fragrance slow-release cooling unit

Abstract

The present invention discloses a fragrance slow-release cooling unit, which comprises: a cooling unit main body (41) having a porous structure, wherein the surface and interior of which have a fragrance component; and an airflow channel (42) axially penetrates through the cooling unit main body (41). Due to the porous characteristic of the cooling unit body (41), the cooling unit body (41) can effectively adsorb spice, aroma components are promoted to be released through heat when smoke flows through the cooling unit body (41), and aroma losses caused when the temperature of the smoke is reduced by the cooling unit can be compensated. The invention further discloses a heating type aerosol generating appliance, an aerosol generating material unit (3), a cooling unit (4) and a filter tip unit (6) are positioned in an outer tube (1) and are sequentially arranged; and the cooling unit (4) can prevent the aerosol source material from falling into other units, is prepared from a porous inorganic material and a porous natural wood material, is non-toxic and harmless after being heated, and is high in safety.

Description

technical field [0001] The invention relates to the field of heat-not-burn cigarettes, in particular to a flavor slow-release cooling unit and a heated aerosol generating product comprising the unit. Background technique [0002] At the beginning of the development of heat-not-burn products, the smoking materials were mainly made of tobacco sheets or paper substrates coated with tobacco substances. With the development of heat-not-burn technology, granular smoking materials gradually appeared, but due to the It is easy to drop during the preparation process of the pod, so the particle-type smoking part often needs to be separated from the adjacent ones by a firmware. As disclosed in the patent CN108078012 A, a heat-not-burn tobacco product containing tobacco particles, the particle catcher consists of a casing, a top cover, a particle end and a base sequentially arranged in the casing, and the particle segment is composed of tobacco The particles are packed between a top co...

Problems solved by technology

It can be seen from the above patents that the part of the firmware used to block the falling of particles in the prior art only plays the role of blocking the falling of particles and ventilation and drainage, and its purpose is single

[0003] On the other hand, most of the spacer units used in low-temperature heat-not-burn products on the market are made of organic polymer materials. Since the spacer unit is close to the smoke particles and the heating sheet, it will soften and deform under high temperature, and will Release harmful substances, there are certain safety hazards

[0004] In addition, the temperature distribution of the smoke after being filtered by the filter tip is 45-90°C. In order to reduce the temperature of the smoke entering the smoker's mouth, there is a cooling section in the cigarette structure of the heat-not-burn cigarette products on the market to reduce the temperature. The flue gas temperature improves the comfort of smoking, but the addition of the cooling section causes the flue gas to lose its aroma while reducing the temperature, which further affects the sensory smoking quality of the product
