Along with the attention of consumers to health problems and the improvement of the demand of individualized experience of cigarette products, the tobacco industry continuously responds to the demand upgrade of consumers and develops various cigarettes with tar and harm reduction. The cigarette heating mode of the non-combustion type cigarette is different from that of the traditional cigarette product, so that the cigarette heating mode can meet the sensory requirements of consumers on the cigarette product and provide healthier smoking experience.

The existing heating non-combustible cigarette mainly comprises a smoking core material section, a hollow supporting section, a cooling section and a filter tip section, wherein the hollow supporting section not only plays a role of supporting the cigarette, but also mainly collects the smoke and assists the cooling section to cool the smoke. At present, the hollow supporting section mainly adopts a hollow paper tube or a hollow acetate fiber rod, and the problems of the hollow paper tube and the hollow acetate fiber rod are as follows: 1. the contact area of the flue gas and the pipe wall of the hollow supporting section is limited, and effective cooling cannot be realized; 2. The residence time of the flue gas in the hollow supporting section is short, the flue gas directly and quickly passes through the hollow supporting section to enter the cooling section, and the cooling efficiency of the hollow supporting section is low; 3. the pipe wall support nature is not enough, can produce great deformation during through the cutter, causes the support performance of supporting the cooling unit to descend, perhaps supports the cooling unit and collapses on the way in production, transportation and warp to give heating not burning cigarette and roll up the system process and increase the degree of difficulty, seriously influence production efficiency and product quality. Consequently, in order to further realize the cooling to the flue gas, at present mainly improve or directly increase the quantity of cooling material to the cooling material of cooling section, but the cooling material is mostly phase change material, and several mouths are being inhaled in the suction, and phase change material collapses and plug up airflow channel, and the resistance-suction rises by a wide margin, influences the suction and experiences.

Therefore, in the field of heating non-combustion cigarette, people hope to obtain a supporting and cooling unit which has strong supporting force, is not easy to deform and collapse, and can cool and increase aroma.

The present invention is proposed in order to solve the above problems.
