Detailed Description
The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.
As shown in fig. 1 and 2, an embodiment of the present invention provides a cooling filter rod, comprising a core layer and an outer wrap layer wrapping the core layer, wherein:
the outer wrapping layer comprises forming paper 1 with a hollow tubular structure; the sandwich layer is a rod-shaped structure, equally spaced wavy bulges 3 are formed on the surface of the TPX film 2, a through smoke passing channel is formed between the TPX film 2, the width extending direction of the TPX film and the length extending direction of the outer cladding layer are in the same direction, and the extending direction of the wavy bulges and the smoke passing channel are in the same direction.
The bar-shaped structure is formed by radially winding and laminating a plurality of TPX films 2, wherein TPX (poly-4-methylpentene-1) is a polyolefin material and has outstanding mechanical properties, high temperature resistance, electrical properties and the like besides the characteristics of the general polyolefin material. The melting point of TPX is as high as 240 ℃, the Vicat softening point is 173 ℃, the TPX can be kept not to deform in the whole pumping process, the TPX has good environment and chemical resistance, has strong resistance to most chemical substances, and reduces the adsorption of the chemical substances in the mainstream smoke. In the embodiment, the TPX film 2 is used as a raw material to prepare the cooling filter stick with the wrinkle structure so as to achieve the purpose of reducing the smoke temperature.
Wherein because the wave is protruding between the adjacent TPX film 2, form numerous cigarette passageways of crossing, on the one hand the flue gas through when crossing the cigarette passageway, increaseed with TPX film 2 area of contact, both can carry out the heat exchange fast, play the effect that reduces the gas temperature, on the other hand numerous cigarette passageways of crossing have improved the throughput of flue gas greatly, have guaranteed the plumpness of smog volume.
Further, the length of the cooling filter stick is 10-20mm, for example, 15mm can be selected, along with the increase of the length of the cooling filter stick, the contact area between the high-temperature smoke and the TPX film 2 is increased, the heat conduction efficiency is higher, the inlet temperature is gradually reduced, and meanwhile, the filter stick can have smaller suction resistance without influencing the suction experience. The preferred embodiment is 15mm, which is the best result of cost and performance considerations, and achieves both cost savings and the best pumping experience.
Further, for standardizing the clearance of passing the cigarette passageway, improve the area of contact with TPX film 2, guarantee good air permeability and air current stability, the interval between the wavy arch 3 of TPX film 2 is 1 mm.
As shown in figure 3, the invention also provides a cigarette which is not burnt when being heated, the structure aspect is a four-section composite structure, the cigarette comprises a filter tip part 4, a cooling part 5, a hollow part 6 and a tobacco part 7 which are sequentially connected, the cooling part 5 adopts the cooling filter stick, and a through cavity channel is formed in the middle of the hollow part 6. In the actual use process, the tobacco part 7 generates high-temperature smoke with the temperature of about 300 ℃ after being heated by a special heat source, the high-temperature smoke rapidly exchanges heat with the TPX film 2 after coming to the cooling part 5 through the hollow part 6, the smoke temperature is reduced, and meanwhile, the TPX film 2 does not deform and release harmful substances in the suction process due to the excellent high-temperature resistance and chemical resistance of the TPX film 2.
Further, the filter portion 4 employs a cellulose acetate filter, which is a cellulose organic acid ester. The filter tip made of the cellulose acetate is a porous membrane material, and has the advantages of high selectivity, large water permeability, environmental protection, no toxicity and simple processing.
Furthermore, the tobacco part 7 comprises a plurality of tobacco shreds wound orderly along the radial direction of the cigarette, the tobacco shreds wound orderly improve the porosity, and the good ventilation and airflow stability in the cigarette are ensured; an approximately linear airflow channel is provided for the circulation of the smoke, the resistance of suction and the adsorption performance of the tobacco shreds to the smoke are reduced, and the smoke passing efficiency is improved.
Further, the length of the hollow part 6 is 10-30mm, and the diameter of the cavity channel of the hollow part 6 is 2-5 mm. Flue gas does the cavity passageway of well kenozooecium 6 and does the short time stay back and pass through cooling portion 5 TPX film 2, the cigarette passageway of crossing of a plurality of penetrations of TPX film 2 increases the area of contact of flue gas and TPX film 2, reduces the temperature of flue gas, and the person's of taking advantage of such lip is difficult for scalding, and simultaneously, numerous cigarette passageways of crossing have improved the throughput of flue gas greatly, have guaranteed the plumpness of cigarette volume, reduce the loss of flue gas, promote the suction quality.
The construction, features and functions of the present invention are described in detail in the embodiments illustrated in the drawings, which are only preferred embodiments of the present invention, but the present invention is not limited by the drawings, and all equivalent embodiments modified or changed according to the idea of the present invention should fall within the protection scope of the present invention without departing from the spirit of the present invention covered by the description and the drawings.
