Description

Aroma-carrying gel stick for cigarettes, filter stick and cooling section of heated nonflammable cigarettes Technical Field The utility model relates to a perfuming material for cigarettes, in particular to a perfuming gel rod for cigarettes. Background The gel-type fragrance-carrying material or the thermosensitive phase-change slow-release fragrance-carrying material has been studied and applied in the cigarette industry, and the material usually takes polyethylene glycol, vegetable wax, animal wax and other substances as main components, and is applied to cigarettes, and remains solid at normal temperature, and when the cigarettes are smoked, the materials are melted into liquid due to temperature rise, so that the wrapped essence components are released. For example, patent application WO 2020211294 A1 discloses a paper-based gel line using phase-change material polyethylene glycol as a fragrance carrier, which is used for cigarettes to make the cigarette have the effect of large fragrance carrying capacity and lasting release, chinese patent application CN 112940856A discloses using waxy material, polyalcohol, polyethylene glycol and other materials to prepare temperature-sensitive fragrance carrying particles for heating nonflammable cigarettes to improve the effect of slowly releasing fragrance, and chinese patent application ZL 202210434722.2, for example, dispersedly filling gel fragrance carrying material into gaps of volcanic stone particles. However, these existing phase-change slow-release fragrance-carrying materials are generally applied to cigarette filter rods in a neutral line form, a particle form or a film coating form, and basically exist in an open or simple embedded state, which results in the defects of irregular cut surface form, powder falling from the cut surface of the product, poor fragrance retaining effect and the like. Disclosure of Invention The utility model aims to solve the problems of irregular appearance, poor fragrance retaining effect and the like commonly existing in gel fragrance-carrying products for cigarettes, and provides a novel fragrance-adding product for cigarettes based on a gel fragrance-carrying technology. In order to achieve the aim, the utility model provides a fragrance-carrying gel rod for cigarettes, which comprises a fragrance-carrying gel core rod 2, wherein the fragrance-carrying gel rod further comprises a high-molecular polymer tube 1, the fragrance-carrying gel core rod 2 is filled in the high-molecular polymer tube 1, and the fragrance-carrying gel core rod 2 is solid in a room temperature environment. In the present utility model, the high molecular polymer tube is a polyethylene tube, a polypropylene tube, a polytetrafluoroethylene tube or a polylactic acid tube. In order to facilitate production and addition into a cigarette filter rod, the outer diameter of the high polymer tube 1 is 2-5 mm, the inner diameter is 1.5-4.5 mm, the wall thickness of the high polymer tube 1 is 0.2-1.0 mm, and the length of the coiled fragrance-carrying gel rod is usually not less than 100m, preferably 1000m, and is orderly arranged and coiled on a shaft core. In the present utility model, the fragrance-carrying gel core rod 2 is in a liquid state when the temperature is higher than 80 ℃. The formulation and process required to prepare the fragrance-carrying gel core rod is known, such as the Wen Minxiang fragrance-carrying material disclosed in CN 117122090a, or other existing phase-change fragrance-carrying materials. As a preferred embodiment, the high molecular polymer tube 1 is transparent or translucent, or has a pattern and/or color. Preferably, the fragrance-carrying gel sticks are cut into 0.5-5.0 cm. The utility model also relates to the application of the aroma-carrying gel stick for cigarettes to filter tow of traditional cigarettes or to heating nonflammable cigarettes. Based on the above, the utility model provides a filter stick containing the aroma-carrying gel stick for cigarettes and a heating non-burning cigarette cooling section containing the aroma-carrying gel stick for cigarettes. In the utility model, after being cut, the front end and the rear end of the high polymer tube are not closed, so that the perfuming effect on the cigarettes is improved after the high polymer tube is applied to the cigarettes. On the other hand, when the cigarette is burnt and smoked, the aroma-carrying gel rod can be subjected to hot melting and flow through due to the action of smoke temperature and smoking airflow, so that essence components in the aroma-carrying gel rod are released. The preparation method of the aroma-carrying gel stick for cigarettes comprises the following steps: 1. weighing phase change material to enable the phase change material to be melted into liquid state in an environment of 80 ℃ (water bath or air bath); 2. adding liquid essence into the molten phase-change material, and fully dispersing until hot-melt fragrance-carrying core l
