Low-temperature cigarette inner film-coated cooling nozzle bar with film attached thereto

Abstract

The invention provides a low-temperature cigarette inner film-coated cooling nozzle bar with a film attached thereto, comprising a composite inner coating film bar and an acetate fiber rod, wherein the inner coating film bar is formed by winding at least two layers of cellulose acetate paper tape and at least two layers of cooling film through a synchronous helical process, and a plurality of cooling films are vertically loaded on the surface of the cooling film of the innermost layer of the inner coating film rod. The inner coating film bar comprises at least two layers of acetate paper tapeand at least two layers of cooling films. As the preparation method is simple, the hollow paper bar can be produced accord to the molding mode of the hollow paper rod, and the preparation of the cooling film with the surface load cooling film is also relatively simple, and the investment of the complex process and equipment is not required; In addition, the contact area of the high temperature flue gas with the cooling material in the cooling nozzle bar is larger than that of the film-coated bar without cooling film, and the flue gas is easy to form turbulence in the cavity, the contact time with the material is long, and the cooling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of new cigarettes, in particular to a film-coated cooling mouthpiece for low-temperature cigarettes with a film attached. Background technique [0002] Low-temperature cigarettes use external heating elements to heat tobacco. The atomization medium in the cigarette, the aroma components in the tobacco and the extra fragrance are heated to generate smoke instead of burning, which reduces the combustion and thermal degradation of tobacco in traditional cigarettes. Hazardous fume constituents of known types produced. The tobacco product reaches the atomization temperature at 250°C to 350°C, and the vaporized high-atomized smoke has a high temperature. It must be cooled by a specially designed mouthpiece before it can enter the consumer's mouth. Adsorption reduces the amount of atomized smoke. [0003] The mouthpiece of low-temperature cigarettes, usually a multi-component mouthpiece, is combined to form a cer...

AI Technical Summary

Problems solved by technology

[0003] The mouthpiece of low-temperature cigarettes, usually a multi-component mouthpiece, is combined to form a certain structure to reduce the temperature of the smoke. The formed smoke channel structure is relatively simple, and it is difficult to form a long gas path structure. The contact time between high-temperature smoke and cooling materials is short. The contact area is also small, and the cooling efficiency is difficult to improve
