Description

a cigarette

Technical field

The invention relates to a cigarette, in particular to a special new cigarette branch for heating non-burning smoking articles.

Background technique

Heating non-burning cigarettes provides consumers with nicotine and tobacco aromas by heating the tobacco instead of burning the tobacco. Compared with conventional cigarettes, the heating of non-burning cigarettes reduces the harmful components in the flue gas by reducing the high-temperature combustion cracking process.

At present, the heating method of heating non-burning cigarettes used in electronic cigarettes includes internal heating and external heating. Internal heating means that the heating component is inserted into the interior of the cigarette to heat the cigarette; external heating means that the heating component surrounds the cigarette Heat the cigarette.

The cigarette-type system (ie, the nicotine production section) for externally heated smoking articles generally has three forms: cut tobacco, tobacco rods, and cigarettes, wherein the tobacco and the tobacco rod are of a single structure, and the advantage is that the structure of the tobacco medium is simple; Inconvenient, when filling, the user's hand will directly contact the smoke medium, causing the smoke medium to be contaminated. At the same time, the smoke medium will remain on the user's hand. When using, the user needs to do extra cleaning work. After the pumping, the smoking fixture is easy to remain in the heating chamber, and needs special cleaning tools to clean, and the temperature of the newly heated tobacco medium is high, and the user directly takes out by hand, which may cause burns. Cigarette-type smog does not have the above two disadvantages, but since the existing cigarette-type smog is internally made of tobacco-like smog, after being placed in a heating chamber, the shredded tobacco is easily left in the heating chamber, requiring Extra cleaning work.

Chinese patent CN106954893A discloses a quaternary composite electric heating non-combustion cigarette, which is composed of a heating section, a diversion section, a cooling section and a filtering section, which can reduce the temperature of the flue gas sucked into the oral cavity and adsorb harmful substances, but the heating section It will still remain in the heating chamber, making the heating chamber difficult to clean.
