Description

Background
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 cigarette mainly comprises a smoking unit, a supporting unit, a cooling section and a filter tip unit, wherein the supporting unit is mainly formed by overlapping and processing two to three layers of paper base materials, the material characteristics of the paper base materials limit the pipe wall thickness of a paper hollow pipe, generally, the pipe wall thickness can only be 0.02-0.05mm, the support performance of the paper hollow pipe is insufficient due to too small pipe wall thickness, the paper hollow pipe can generate large deformation when passing through a cutter, the support performance of the supporting unit is reduced, or the supporting unit collapses and deforms in production and transportation, so that the difficulty is increased in the cigarette rolling process of the heating cigarette, and the production efficiency and the product quality are seriously affected.
In addition, the supporting element not only plays the effect of supporting to a cigarette, and more importantly assembles the flue gas and assists the cooling section to the flue gas cooling, and in order to increase consumer's suction quality, carries out the fragtant also indispensable to the flue gas. However, the cooling effect and the flavoring effect of the current supporting unit in the form of a paper tube on flue gas are still not good due to the following two reasons: 1. the contact area between the flue gas and the pipe wall of the supporting unit is limited, and effective cooling cannot be realized; 2. the adsorption capacity of the tube wall of the paper tube to the spice is less, and if the adsorption capacity to the spice is improved, the support performance of the tube wall of the paper tube is inevitably influenced.
Therefore, it is desirable to develop a supporting unit which has strong supporting force and can give consideration to the cooling effect, assist the cooling section to realize better cooling and flavoring effects on the flue gas, and even replace the cooling section.
The present invention has been made to solve the above problems.
