Description
Technical Field
The invention relates to the field of heating non-combustible tobacco products, in particular to a cigarette which is non-combustible by heating and a smoking product comprising the same.
Background
Currently available heated non-combustible products in the market are primarily non-combustible heating of aerosol-forming articles containing tobacco material or plant material at temperatures below 350 ℃ to release nicotine and plant aroma therein.
Compared with the traditional cigarette, harmful chemical substances released by heating the non-combustible cigarette product are obviously reduced, but the temperature of the aerosol produced under the condition is higher, the lips and the tongue of a user can easily feel high-temperature burning sensation in the smoking process, the traditional non-combustible cigarette is cooled by adding different cooling materials which are PLA heat shrinkage films and the like, the rapid cooling capacity is limited, and the user experience is poorer.
Disclosure of Invention
In view of the above, it is desirable to provide a smoking article comprising a non-combustible tobacco rod, which can significantly reduce the temperature of the aerosol to be drawn, in view of the problem of limited cooling capacity of the non-combustible tobacco rod.
A heated non-combustible tobacco rod comprising: the device comprises a hollow pipe, and an aerosol generating unit, a flow guide unit and a filtering unit which are positioned in the hollow pipe and are sequentially connected along the length direction of the hollow pipe;
the aerosol-generating unit comprises a plant core material;
the flow guide unit comprises a gas-permeable tubular wrapping piece and a flow guide piece positioned in the wrapping piece, wherein the flow guide piece is composed of a plurality of flow guide elements and is provided with a plurality of zigzag gas channels;
the flow guide piece is loaded with a heat dissipation mixture, the heat dissipation mixture comprises essence and a heat dissipation auxiliary agent, and the heat dissipation auxiliary agent is selected from any one or two of essence in cyclodextrin and cyclodextrin derivatives;
the filter unit includes a cylindrical filter member.
In one embodiment, the mass ratio of the heat dissipation auxiliary agent to the essence in the heat dissipation mixture is (1-10): 1, and preferably (2-4): 1.
In one embodiment, the cyclodextrin derivative is modified by hydrophilic modification of hydroxyl groups on glucose units, and preferably, the cyclodextrin derivative is selected from any one or more of hydroxypropyl-beta-cyclodextrin, carboxymethyl-beta-cyclodextrin and 2, 6-dimethyl-beta-cyclodextrin.
In one embodiment, the fragrance is at least one of a water-soluble and an alcohol-soluble fragrance.
In one embodiment, the zigzag gas channel structure is a corrugated gap formed between the flow guide elements, a knurled structure on the surface of the flow guide elements or a pore formed by stacking granular flow guide elements.
In one embodiment, the flow guide member is of a one-piece structure or a split structure.
In one embodiment, the flow guiding element is a polyester film, a polylactic acid film or a kraft paper which is subjected to wrinkling or knurling treatment, or the flow guiding element is a porous particle, preferably the porous particle is a porous plant material, preferably the porous particle is at least one selected from the group consisting of a microwave expansion treated porous plant material, a microwave expansion nutshell, a porous activated carbon, a porous ceramic and a molecular sieve.
In one embodiment, the gas permeable tubular wrapper is a porous material that completely wraps the structure or a structure that is open at both ends.
In one embodiment, the filter element is an acetate fiber tow, a propionate fiber tow, a polyester fiber tow or a polylactic acid tow, or is composed of a plurality of plant particles, and the plant particles are internally provided with porous structures formed by microwave expansion technology treatment.
In one embodiment, the length ratio of the aerosol generation unit to the flow guide unit to the filter unit is (1-1.6): (1-3): 1.
