Description

Technical Field

[0001] The invention belongs to the field of heated cigarettes, and in particular relates to a heated cigarette capable of adjusting the air permeability and air permeability position of a tube wall and an adjustment method. Background Art

[0002] As consumers pay more attention to health issues and demand for personalized experience of cigarette products, the tobacco industry continues to respond to the upgrading of consumer demand and develop various heated cigarettes with reduced tar and harm. Among them, heat-not-burn cigarettes are different from traditional cigarette products in that their heating method is different, which enables them to meet consumers' sensory needs for cigarette products while providing a healthier smoking experience.

[0003] Existing heated cigarettes mainly include a smoking core material section, a hollow support section, a cooling section and a filtering section. In order to introduce air, increase ventilation, and effectively reduce smoke temperature, heated cigarettes usually use an online laser punching method to punch holes in the hollow support section of the heated cigarette, punch through the hollow support section wall and the forming paper and tipping paper wrapping the hollow support section, form ventilation holes, and introduce air. However, this method still has the following problems: 1. The online laser punching process has high requirements on the material and thickness of the hollow support section wall. First, the material of the hollow support section wall cannot collapse during the online laser punching process, and the hollow support section wall cannot be particularly thick, so as to avoid the online laser 1. The holes cannot be punched through; 2. The online laser drilling process has very high requirements on laser power. If the laser drilling equipment fails to punch through the wall of the hollow support segment, the heated cigarettes will be unqualified and the smoke temperature will be too hot; 3. At present, ventilation holes are formed by punching through the hollow support segment and the forming paper and tipping paper that wrap the hollow support segment. The outside air directly enters the hollow support segment through the ventilation holes. The air is introduced into the ventilation holes at a fast speed, the contact area between the introduced air and the smoke is limited, and the mixing is uneven. As a result, although the amount of smoke inhaled into the consumer's mouth has increased, the smoke concentration is low, and a large amount of air is obviously mixed in the smoke, which seriously reduces the smoking quality.

[0004] In addition, the use of physical perforation to make the heated cigarette tube wall ventilated still has the problem of unadjustable permeability and fixed permeability position. Since physical perforation can only be used to introduce air, the permeability is fixed with the size of the hole. However, with the change of the smoking section material or the change of the adapted smoking device, the permeability and permeability position of the heated cigarette can be adjusted.

[0005] Therefore, it is desirable to design a heated cigarette that can ensure both the cooling effect on smoke and the smoke volume and smoke quality, and the air permeability and air permeability of the heated cigarette can be adjusted.

[0006] In order to solve the above problems, the present invention is proposed. Summary of the invention

[0007] The first aspect of the present invention provides a heating cigarette with adjustable tube wall permeability and ventilation position, the heating cigarette with adjustable tube wall permeability and ventilation position comprises a smoking section 1 and a heating cigarette filter rod with natural ventilation function, and the two are assembled and formed by a shaping paper 4; at least part of the outer side of the shaping paper 4 wrapping the heating cigarette filter rod with natural ventilation function is also provided with a tipping paper 5;

[0008] From the far lip end to the near lip end, the heating cigarette filter rod with natural ventilation function includes a smoke extraction section 2 and a functional filter rod section 3 in sequence. The smoke extraction section 2 itself has a ventilation function, and the outside air can enter the interior of the heating cigarette through the smoke extraction section 2;

[0009] The tipping paper 5 only partially wraps the smoke extraction section 2, and at least a part of the area on the side of the smoke extraction section 2 close to the smoking section 1 only has the shaping paper 4 on the outside, and is not wrapped by the tipping paper 5;

[0010] The shaping paper 4 is air-permeable, the tipping paper 5 is air-impermeable, and the length and position of the tipping paper 5 are adjustable.

[0011] Preferably, the smoke extraction section 2 is a hollow structure, which includes a tube wall 21 and a tube cavity 22. The tube wall 21 does not need to be perforated, and it has a ventilation function. The tube wall 21 has a vent hole, and the outside air can enter the tube cavity 22 through the vent hole in the tube wall 21. The cross-sectional area of ​​the tube cavity 22 is not limited to a circle, and can also be any shape such as a triangle, a polygon, or a five-pointed star.

[0012] Preferably, the tipping paper 5 covers 1 / 6-5 / 6 of the axial length of the smoke extraction section 2 .

[0013] Preferably, the air permeability of the shaping paper 4 is 1000-10000 CU.

[0014] Preferably, the tube wall 21 can be formed by bonding and extruding particles, and the pores between the particles after forming serve as vents, so that the tube wall 21 itself has a breathable function;

[0015] The diameter of the particles is 200-25000 microns; after the particles form the wall of the hollow tube, the thickness of the tube wall 21 is 1.0-2.0 mm, and the pores between the particles in the tube wall 21 are dispersed, and the porosity is 50-80%.

[0016] Preferably, the particles are selected from organic particles or inorganic particles, the inorganic particles include alumina, zirconium oxide, calcium carbonate, glass beads, silicon dioxide, iron, copper, aluminum, gold, platinum, magnesium silicate balls or calcium sulfate; the organic particles include cellulose acetate, cellulose acetate propionate, cellulose acetate butyrate, microcrystalline cellulose, sucrose powder, dextrin, lactose, powdered sugar, glucose, mannitol, starch, methyl cellulose, ethyl cellulose, polylactic acid, polyethylene, polypropylene, polyhydroxybutyrate, poly-ε-caprolactone, polyglycolic acid, polyhydroxyalkanoate, and at least one of starch-based thermoplastic resins.

[0017] Preferably, the binder between the particles includes: polyethylene, polypropylene, polylactic acid, polyolefin, polyester, polyamide, polyacrylic polyvinyl compound, polytetrafluoroethylene, polyetheretherketone, polyethylene terephthalate, polybutylene terephthalate, polycyclohexanedimethylene terephthalate, polypropylene terephthalate, polyacrylate, polymethyl methacrylate, acrylonitrile-butadiene-styrene, styrene-acrylonitrile, styrene-butadiene, styrene-maleic acid, cellulose acetate, cellulose acetate butyrate, plasticized cellulose plastic, cellulose propionate, ethyl cellulose, any derivatives thereof, any copolymers thereof, and at least one thereof, and any combination thereof.

[0018] Preferably, the tube wall 21 is an acetate fiber bundle, and the amount of the acetate fiber bundle is medium-density. After the acetate fiber bundle forms the wall of the hollow tube, the thickness of the tube wall 21 is 1.0-3.0 mm. At this time, the amount of the acetate fiber bundle is medium-density, and when the size is a filter rod circumference of 19.8 mm, 2000-4500 strands are filled.

[0019] Preferably, the tube wall 21 is made of a breathable ceramic material.

[0020] That is to say, in this heated cigarette structure, the shaping paper 4 plays two assembly roles: (1) the smoke extraction section 2 and the functional filter rod section 3 are assembled to form the heated cigarette filter rod with natural ventilation function; (2) the heated cigarette filter rod with natural ventilation function and the smoking section 1 are assembled to form a heated cigarette. The tipping paper does not play an assembly role, but controls the ventilation amount and ventilation position of the smoke extraction section 2 by controlling the length of the tipping paper. At the same time, the tipping paper also plays a conventional role such as printing patterns and logos.

[0021] The second aspect of the present invention provides a method for adjusting the heated cigarette with adjustable tube wall permeability and ventilation position according to the first aspect of the present invention, which can adjust the permeability and ventilation position of the smoke extraction section 2 by adjusting the size and position of the area covered by the tipping paper 5 on the smoke extraction section 2, thereby adjusting the permeability and ventilation position of the heated cigarette.

[0022] In addition, the heating cigarette filter rod with natural ventilation function of the present invention is not limited to only including the smoke extraction section 2 and the functional filter rod section 3. According to actual needs, it can also be a ternary composite structure, and other functional sections such as a supporting section, a cooling section, and a flavoring section can be added.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The heating cigarette of the present invention can adjust the air permeability and air permeability position of the tube wall, which includes a smoke extraction section 2 with its own air permeability function, and the outside air can enter the interior of the heating cigarette through the smoke extraction section 2; the tipping paper 5 only partially wraps the smoke extraction section 2, and the outer side of the partial area of ​​the smoke extraction section 2 close to the smoking section 1 has only the shaping paper 4, and the tipping paper 5 is not wrapped; and the shaping paper 4 is air permeable, the tipping paper 5 is airtight, and the length and position of the tipping paper 5 are adjustable, so that the air permeability and air permeability position of the smoke extraction section 2 can be adjusted by adjusting the size and position of the area covered by the tipping paper 5, thereby adjusting the air permeability and air permeability position of the heating cigarette. The cigarette structure of the present invention can more flexibly control the air permeability and air permeability position of the smoke extraction section 2 by controlling the length of the tipping paper 5.

[0025] 2. The heating cigarette filter rod with natural ventilation function of the present invention comprises a smoke extraction section 2, wherein the tube wall 21 of the smoke extraction section 2 does not need to be punched, and it has a ventilation function by itself. The tube wall 21 has ventilation holes, and the outside air can enter the tube cavity 22 through the ventilation holes in the tube wall 21. That is to say, the tube wall 21 itself has pores and has a natural ventilation effect. The forming paper 4 and the tipping paper 5 are used in combination to make the cooling section tube wall breathable. The outside air enters the interior of the heating cigarette through the pores and mixes with the smoke, thereby achieving the purpose of introducing air into the interior of the heating cigarette. No holes are needed to be punched, and the problems caused by punching holes in the tube wall 21 of the smoke extraction section 2 are avoided.

[0026] 3. In a preferred embodiment of the present invention, the tube wall 21 can be formed by extrusion of particles, and the pores between the particles after forming play a role of natural ventilation; after the particles form a hollow tube, the pores between the particles in the tube wall are dispersed. Compared with directly punching holes in the cooling section, the air introduced into the particle-form smoke extraction section of the present invention is more dispersed. While ensuring that the amount of air introduced can achieve cooling, it can also evenly introduce air into the heated cigarette, so that the introduced air and smoke are mixed more evenly, which solves the problem that only a large amount of air is introduced to achieve a cooling effect, but it leads to uneven mixing of air and smoke and poor smoke quality.

[0027] 4. If the particles are used as solid cooling rods, although the cooling effect is good, the smoke has to pass through the particle gaps in the solid cooling rod to reach the filter tip for consumers to inhale, which results in the solid cooling rod adsorbing too much smoke. While the present invention introduces air to reduce the smoke temperature, the selection of particle materials is also critical. The particle materials of the present invention are selected from some materials with cooling effects. When the smoke passes through, the wall material of the smoke extraction section can also play the role of reducing the smoke temperature.

[0028] 5. In a preferred embodiment of the present invention, the tube wall 21 is an acetate fiber bundle, which is not a traditional acetate fiber bundle used for filter tips. The acetate fiber bundle used for the tube wall 21 in the present invention is a medium-branched one, which makes the acetate fiber bundle itself porous and breathable, just like a window screen with a mesh. Compared with directly punching holes in the cooling section, the air introduced into the smoke extraction section of the acetate fiber bundle of the present invention is more dispersed. While ensuring that the amount of air introduced is sufficient to achieve cooling, it can also evenly introduce air into the heated cigarette, so that the introduced air and smoke are mixed more evenly, solving the problem that, as in the previous punching, only a large amount of air is introduced to achieve a cooling effect, but the air and smoke are mixed unevenly and the smoke quality is poor.

[0029] 6. In a preferred embodiment of the present invention, the tube wall 21 can also be made of a breathable ceramic material, which can not only have its own breathable function but also play a supporting role. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Example 3

[0059] For the heated cigarette sample 1 prepared in Example 1 and the heated cigarette sample 2 prepared in Example 2, according to the QYNZY.J07.022-2015 standard, 20 professional sensory evaluation personnel at or above the provincial level conducted a sensory evaluation on the cigarette samples.

[0060] Table 1 Sensory quality record of new cigarettes

[0061] Standard basis: QYNZY.J07.022-2015

[0062]

[0063] It can be seen from Table 1 above that sample 1 is superior to sample 2 in terms of aroma and taste. This is because the air permeability of sample 2 is greater than that of sample 1, resulting in a larger amount of air introduced, which reduces the aroma of the smoke itself. Therefore, according to different smoking core materials, the air permeability and ventilation position of the smoke extraction section should be appropriately adjusted.
