Technical field

The present invention relates to a kind of cooling filter stick, application and cigarette, belong to technical field of cigarette production.

Background technique

In traditional cigarette aspiration procedure, the heat that cigarette combustion cone generates can be brought by main flume to filter tip, and with Cigarette smoking process, be stepped up by the flue-gas temperature of filter tip.Studies have shown that suction close at the end of filter end cigarette Temperature degree may be up to 70-80 DEG C, and excessively high filter tip temperature will affect the rejection effect of filter tip, while will affect consumer to flue gas The evaluation of aesthetic quality.The appropriate flue-gas temperature that reduces is necessary.

Low temperature cigarette is to carry out heating to tobacco product by external heating element to generate smog, and usual tobacco product exists Reach atomization condition under conditions of 250-350 DEG C, to guarantee that filter end requires low adsorption even without suction to amount of smoke under normal conditions Attached, high-temperature atomizing flue gas can be higher than the temperature that traditional cigarette is burnt by the temperature that filter tip enters oral cavity.Therefore appropriate to reduce cigarette Temperature degree is also the key technology of low temperature cigarette development.

Chinese patent CN201510045745.4 provides a kind of filter tip and cigarette, adds phase-change material by filter end Reduce flue-gas temperature, used phase-change material is hydrated inorganic salt and urea admixture, usage mode is to be sprayed on vinegar fibre On mouth stick or crystal is placed between two-section filter tip, be this hydrated salt usage mode well known to industry and effect be exist it is tight Weight problem.

Chinese patent CN101396173 provides the method and its cigarette structure of a kind of cigarette vortex temperature-reduction fragrance-protecting, be Swirl channel is set identical as air before cigarette filter, reaches cooling effect, structure is more complicated and is unsuitable for low-temperature heat not Burn cigarette.

Summary of the invention

Present invention solves the technical problem that be, when cigarette (including traditional cigarette and low-temperature heat do not burn cigarette) suction, The smoke temperature generated of burning is higher, has burning sensation to consumer oral cavity, influences suction experience.

In order to solve the above-mentioned technical problem, technical scheme is as follows: a kind of cooling filter stick, particles cured by cooling down It is molded with, and there is porous structure；Effecive porosity inside the cooling filter stick is 65-95%.

In the present invention, cooling filter stick has porous structure, is molded with by cooling is particles cured, and inside has complicated and connects Continuous channel, after high-temperature flue gas enters cooling filter stick from cooling filter stick one end, high-temperature flue gas rapid dispersion is in cooling filter stick In hole, and heat exchange is come into full contact with cooling particle, realizes cooling；In addition, stroke of the high-temperature flue gas in cooling filter stick is long, obtain The good cooling effect obtained.

Further, the cooling filter stick passes through adhesive bonding curing molding by cooling particle.

Further, the cooling filter stick is by compact grain microwave or heat cure obtained by molding, and further, cool down filter stick Middle moisture content is 5-12wt%.

Further, the cooling particle is spherical or subsphaeroidal.The inside of spherical or subsphaeroidal certifiable detemperature rate stick There are complicated enough and continuous exhaust gases passes；Further, the cooling particle is closely knit particle, the closely knit certifiable suction of particle Attached ability is as small as possible, be especially suitable for low temperature do not burn cigarette filter rod cooling.

Further, the porous structure is class honeycomb.

Further, it after the cooling particle is sufficiently mixed by matrix powder, hot melt adhesive powder, excipient, water, is granulated, Screening obtains.Wherein, matrix powder, hot melt adhesive powder, excipient, water proportion can choose as needed, can normally smoothly Granulating and forming.

Described matrix powder includes at least one of vegetable material, inorganic material, metal powder.

Further, the vegetable material includes tobacco material, straw, peanut shell, bagasse, corncob, pericarp, fragrance At least one of property plant；The inorganic material includes at least one of powdered carbon, clay, calcium carbonate, silica；The gold Belonging to powder includes at least one of iron powder, aluminium oxide, copper powder.

Vegetable material can be minimized cost using one side, and another aspect fragrance plant also has in filter stick assigns Perfume effect.Inorganic material and metal powder will not introduce external peculiar smell, and metallic powder is more conducive to cooling effect It plays.

Further, the fragrance plant includes at least one of santal, agalloch eaglewood, cloves, coffee, fennel.

The hot melt adhesive powder includes at least one of EVA, TPU, PE, PA, PES.Can guarantee particle molding and The molding of grain stick.

Quality accounting of the hot melt adhesive powder in cooling particle is 5%-50%, preferably 10%-40%, Qi Tacheng Point content can be adjusted as needed.Suitable hot melt adhesive dosage can guarantee enough bonding forces, it is excessive then may be stifled when melting Channel is filled in, cooling effect is influenced.

The excipient includes microcrystalline cellulose, pre-gelatinized starch.

The partial size of the cooling particle is 10-50 mesh.Further, moisture content is 7-15wt% in cooling particle.Water Point content is maintained at content range appropriate, it is ensured that cooling filter stick does not go mouldy, while making to keep during cigarette smoking Preferable mouthfeel.

Further, the effecive porosity inside the cooling filter stick is 80-95%.

The production method of above-mentioned cooling filter stick includes the following steps:

1) by least one of vegetable material/inorganic material/metal powder, hot melt adhesive powder, microcrystalline cellulose, pre- paste Change starch, water etc. to be sufficiently mixed, be granulated, dry, screening obtains the cooling particle of appropriate particle size；

2) cool down filter stick needed for being by the cylinder that cooling grain forming obtained is certain size.Further, described Contain phase-change material in cooling particle；Further, phase-change material is not contained in the cooling particle.

Application of the cooling filter stick as described above in production cigarette.

A kind of cigarette, including sequentially connected smoke portion and filter tip, the filter tip is interior to be equipped with cooling as described above Filter stick.

Further, it is that can be used as cigarette cooling to filter that the cooling filter stick is compound by a certain percentage with other regular plugs Stick.Suitable cooling filter lengths can be chosen according to cooling extent and the needs of technique.

Further, the regular plug is vinegar fibre filter stick, propene fibre filter stick, paper filter stick, blank pipe stick etc..

The cooling filter stick can be used for conventional cigarette or low-temperature heat is not burnt cigarette.

The cooling filter stick connects pipe tobacco section processed or smoke section for aspirating, wherein cooling filter stick is close to pipe tobacco/smoke section.

Compared with prior art, technical solution of the present invention bring technical effect:

(1) stuffy diluted means are used for the first time, and flue gas is significantly reduced based on Physical temperature-lowering principle and enters oral cavity Temperature, cooling extent is up to 50% or more；

(2) use full grain forming simple for filter stick form, novel, this completely new filter stick form can realize industrial metaplasia It produces, low in cost, good cooling effect；

(3) without adding phase-change material, that is, it can reach good cooling effect, without having to worry about in aspiration procedure, phase transformation material Expect state change and cause cooling filter stick ventilation unsmooth, draw resistance is small, and suction experience sense is good.

Specific embodiment

Following embodiment is intended to illustrate summary of the invention, rather than further limits to the scope of the present invention.
