AI Technical Summary

Technical Problem

The existing heated tobacco products require equipment calibration and adjustment when switching between different types, resulting in low production efficiency. Furthermore, tar seepage during combustion affects the appearance and smoking experience.

Method used

The outer paper of the heated tobacco stick is divided into multiple layers using a group processing method. The inner cigarette paper is aluminum foil non-ventilated paper, and the outer cigarette paper is absorbent paper. The tobacco is wrapped layer by layer on the outside of the cigarette. Auxiliary heating strips and central heating rods are added to achieve uniform temperature and tar adsorption.

Benefits of technology

It improves production efficiency, ensures the applicability of cigarettes of different specifications, effectively prevents tar leakage, and enhances the smoking experience.

Abstract

The application provides a heating non-combustible cigarette structure and a manufacturing method, and relates to the technical field of cigarette manufacturing.The heating non-combustible cigarette structure comprises inner-layer cigarette paper arranged on the outer side of tobacco and outer-layer cigarette paper arranged on the outer side of the inner-layer cigarette paper.The inner-layer cigarette paper is non-ventilation paper provided with an aluminum foil, and the outer-layer cigarette paper is adsorption paper, so that the inner-layer cigarette paper and the outer-layer cigarette paper are processed in groups and are sequentially wrapped on the outer side of the tobacco during cigarette manufacturing.The application is simple in structure, and the outer-layer paper of the heating non-combustible cigarette is divided into a multi-layer structure.The multi-layer paper is processed in groups and is wrapped layer by layer.The same base paper is used in the processing mode, and the functional layers are different, so that the processing can be applied to different specifications and different cigarettes, and the production efficiency is high.The aluminum foil is added to the multi-layer paper, so that the temperature is uniform, and the adsorption layer prevents tar from seeping out, thereby effectively improving the smoking experience of the cigarette.
