Filter unit capable of lowering air flow temperature and supplementing beneficial components

Abstract

The invention discloses a filter unit capable of lowering the air flow temperature and supplementing beneficial components. The filter unit is a cylinder of multiple channels formed by folding and gathering composite sheets through embossing along embossing lines, and the composite sheets are formed by bonding a polymer film and cellulose paper. The filter unit can effectively lower the air flow temperature, the aerosol temperature of an oral cavity reaches 100 DEG C or lower, the temperature reaches 70 DEG C or below generally, aroma components and the nicotine content can be increased, satisfaction is improved, the functions are achieved at the same time, and then the structure of an aerosol generation materials is simplified; aerosol filtering is effectively lowered, and a consumer canbetter satisfy the smog amount. Particularly, the quality needed by aerosol generation materials is heated and not combusted. According to the composite sheets, the physical hardness needed by the filter unit and the functional requirement are improved, and the usability, applicability and functionality of the filter unit are effectively enhanced.

Description

technical field [0001] The invention relates to a filter unit capable of reducing airflow temperature and supplementing beneficial components, and belongs to the technical field of cigarette filtering. Background technique [0002] The aerosol-generating substrate generally contains tobacco components, and is composed of shredded tobacco, tobacco sheet, or the like as the main substrate, which can be filled in a cylindrical shape formed by wrapping cigarette paper in an orderly or disorderly manner. inside the cavity. These materials also include propylene glycol, glycerin, and aromatizing ingredients, so that after heating or burning, they will generate the scented aerosol that consumers expect. [0003] It is known technology to produce the aerosols desired by consumers for inhalation by burning or heating without burning a substrate, such as a substrate containing tobacco. Under normal circumstances, when burning a base material containing tobacco, the temperature is as...

AI Technical Summary

Problems solved by technology

Low filter unit technology is usually achieved by reducing the suction resistance of filter rods, such as reducing the filling amount of tow in filter rods, and using tubes with large pores (hollow paper tubes, hollow acetate tubes, etc. combined with acetate units), the The technology only solves the problem of reducing the excessive interception of aerosol through low filtration, and realizes the natural reduction of aerosol temperature to a certain extent, but fails to further reduce the temperature more effectively, resulting in the temperature of the aerosol reaching the oral cavity reaching above 100°C instead

[0004] In addition, heat-not-burn products release less beneficial ingredients (such as aroma components, nicotine, etc.) in the base material due to the lower heating temperature, which makes such products less acceptable to consumers than combustion products
