Abstract
The utility model belongs to the field of heating non-combustible cigarette, in particular to an airtight heating cigarette. The cigarette comprises a tobacco section (1), a low-suction-resistance section (2) and a functional filter section (3) which are coaxially abutted in sequence from upstream to downstream, and an external wrapping piece (4) wraps the cigarette; the low-suction-resistance section (2) is a pipe body with an axial central cavity (2-1) and circumferential side wall through holes (2-2), and the number of the side wall through holes (2-2) is at least one; the circumference and/or the upstream end face of the tobacco section (1) are wrapped by a paper base material or a foil base material with air impermeability or controllable air permeability to form a closed system. The utility model discloses designed a closed cigarette for the first time, because the fresh flue gas that forms has the replacement effect to a cigarette inside atmosphere, the oxygen content in the cigarette can reduce along with heating process, even the rising temperature, also can not take place the burning. Therefore, the heating temperature can be increased to fully release the tobacco aroma components and increase the smoke volume.
Description
Technical Field
The utility model belongs to the field of heating non-combustible cigarette, in particular to an airtight heating cigarette.
Background
Traditional tobacco has been in the past for centuries and has been incorporated into the lives of most smokers. In recent years, along with the improvement of living standard of people, the problems of smoking, health, harm of second-hand smoke and the like are more and more emphasized by people, and the harmfulness brought by the traditional tobacco products is more and more prominent. Meanwhile, with the implementation of WHO tobacco control framework convention, especially the gradual expansion of smoking ban in public places of all countries in the world, the development environment of tobacco products has been changed significantly and profoundly, and the structure of tobacco products is being adjusted rapidly towards the development direction of diversification and no smoke. The new tobacco products gradually become the realistic choice for various large transnational tobacco enterprises to deal with the sales of the traditional tobacco products.
At present, most of the non-combustible heating cigarettes adopt air as a carrier of smoke, in order to ensure that the tobacco is not combusted, the applied heating temperature is usually lower and generally does not exceed 300 ℃, compared with the traditional cigarette, the tobacco aroma components of the novel non-combustible heating cigarette are difficult to completely release, and the smoke quantity is insufficient, so that the cigarette is difficult to be accepted by traditional smokers. In addition, in order to ensure air circulation, most of the tobacco ends of the cigarettes which are not heated and combusted are in an open structure, namely, the cut tobacco or the reconstituted tobacco sheets are directly exposed outside or are connected with the outside atmosphere through a certain airflow channel, and tobacco residues can drop off and easily pollute the smoking set in the process of pulling out the smoke bomb after smoking is finished, so that the smoking set is cleaned by the tobacco in a certain time.
In order to solve the above problems, the present invention is provided.
SUMMERY OF THE UTILITY MODEL
The utility model provides a closed heating type cigarette, which comprises a tobacco section 1, a low-suction-resistance section 2 and a functional filter section 3 which are coaxially butted in sequence from the upstream to the downstream, wherein an external wrapping piece 4 is wrapped outside the cigarette;
the low-suction-resistance section 2 is a pipe body with an axial central cavity 2-1 and circumferential side wall through holes 2-2, and the number of the side wall through holes 2-2 is at least one;
the circumference and/or the upstream end face of the tobacco section 1 are wrapped by a paper base material or a foil base material with air impermeability or controllable air permeability to form a closed system.
Preferably, a coaxial through hole 4-1 is arranged on the outer wrapping piece 4 at a position corresponding to the side wall through hole 2-2, and the aperture of the coaxial through hole 4-1 is not smaller than that of the side wall through hole 3-2.
Preferably, the low suction resistance section 2 may be an empty pipe.
Preferably, the functional filter segment 3 comprises a cooling segment 3-1 and a filter segment 3-2.
Preferably, the tobacco segment 1 comprises tobacco cut, tobacco flakes, tobacco particles, tobacco shaped bodies or tobacco containing gel bodies therein.
The technical scheme can be freely combined on the premise of no contradiction.
The utility model discloses following beneficial effect has:
1. the utility model discloses designed a closed cigarette for the first time, it matches the heating type smoking set and uses, because the fresh flue gas that forms has the replacement effect to a cigarette inside atmosphere, and the oxygen content in the cigarette is can be along with the heating process reduces, at this moment, even rise the heating temperature, also can not take place the combustion phenomenon. Therefore, the heating temperature can be increased to fully release the tobacco aroma components and increase the smoke volume.
2. The one end that sealed cigarette tobacco section contact cigarette held the chamber is sealed, the condition that tobacco residue dropped and polluted the smoking set can not appear.
3. The utility model discloses a closed cigarette design has the low resistance section of inhaling that has axial direction center cavity and circumference lateral wall through-hole, and suction in-process outside air gets into from the lateral wall through-hole, mixes with the smog that tobacco section heating produced in the cavity and forms mainstream smoke and supplies the people's suction. Meanwhile, in the process of suction, the external air enters from the through hole of the side wall, the air flow rate of the low suction resistance section is high, the pressure is low, and the smoke of the tobacco section is extracted. In addition, the outside air has a cooling effect on the smoke at the same time.

Detailed Description
The present invention will be further described with reference to the following detailed description.
Example 1
A closed heating type cigarette comprises a tobacco section 1, a low-suction-resistance section 2 and a functional filter section 3 which are coaxially abutted in sequence from upstream to downstream, wherein the cigarette is externally wrapped with an external wrapping piece 4 tipping paper;
the low-suction-resistance section 2 is a hollow paper tube with an axial central cavity 2-1 and circumferential side wall through holes 2-2, and the number of the side wall through holes 2-2 is 2;
the circumference and the upstream end face of the tobacco section 1 are wrapped by an airtight aluminum foil to form a closed system.
Coaxial through holes 4-1 are formed in the outer wrapping piece 4 at positions corresponding to the side wall through holes 2-2, and the aperture of each coaxial through hole 4-1 is not smaller than that of the side wall through hole 3-2.
