Technical Field

The invention relates to the technical field of tobacco smoking sets, in particular to a cigarette rod and a smoking set which are not combusted by heating and application.

Background

Along with the improvement of the living standard of people, people pay more and more attention to the health problem of the people, and the health problem of smoking is concerned in recent years. Various tobacco products replacing traditional burning cigarettes are developed by various domestic and overseas large tobacco enterprises in order to meet the changing consumption requirements. Of these growing products, heating non-combustible cigarettes is the outperforming industry in recent years and a future hotspot in the global tobacco industry.

The cigarette which is not burnt is heated by the heating core of the smoking set to heat the cigarette bullet part of the cigarette, smoke is generated below 400 ℃, and the smoke taste is similar to that of the traditional cigarette, so the cigarette is accepted by many smokers. At present, the main tobacco shred distribution forms of the cigarette cartridges which are not burnt and are heated in the global market are divided into ordered filling and disordered filling. The heating core for heating the non-combustion smoking set is divided into inner core heating and circumferential heating, wherein the heating core for heating the inner core mainly adopts two modes of sheet heating and needle heating. The sheet type heating core can be effectively contacted with tobacco shreds in a cigarette bullet in the smoking process of heating cigarettes, so that the release of the smoke quantity is sufficient; the space that the needle type heating core inserts heating cigarette inside is less, can keep the higher integrality of the inside pipe tobacco of cigarette bullet for pipe tobacco internal conduction is comparatively even, releases stable flue gas volume. Although the sheet heater core and the pin heater core have advantages, they have disadvantages: the sheet type heating core has insufficient and asymmetric heating in the edge area in the cylindrical smoke cartridge, and the heating area is not ideal; the needle type heating core is thin, lacks strength, is easy to break in use, has small heating area and releases little smoke; therefore, the smoke release amount of the heating core in the sheet type and the needle type is insufficient compared with the traditional cigarette, and the mouth-to-mouth release is unstable.

To solve the above problems, there are two main solutions, one is to increase the temperature of the heating core; another is to increase the area of the heater core so that its contact area with the inside of the cartridge is increased. However, the two solutions described above lead to further corresponding problems: 1. if the temperature of the heating core is increased, the cigarette has the problem of overheating smoke temperature in the smoking process, because the cigarette which is not combusted by heating is shorter, and the heating temperature is increased, the smoke temperature is increased, so that the phenomenon of burning the mouth is generated; 2. the contact area of the overlarge heating core can push out ordered slices or unordered cut tobacco in the cigarette cartridge, and the lost slices and cut tobacco can greatly reduce the heating efficiency and the smoke release amount.

Disclosure of Invention

The invention provides a heating non-combustion cigarette, which comprises a smoking section and a filtering section, wherein a supporting section is arranged between the smoking section and the filtering section, the supporting section is of a rod-shaped structure, and a plurality of air inlet channels are axially arranged in the supporting section.

The smoking section is filled with tobacco, and the filter section is used for reducing smoke, tar, suspended particles generated during combustion and the like at the inlet of a smoker when smoking; the support section is positioned between the smoke generating section and the filtering section and has the second function, firstly, a plurality of air inlet channels are arranged in the axial direction of the support section, smoke can pass through the air inlet channels, and the smoke is cooled when the smoke passes through the air inlet channels, so that the burning of a mouth is avoided; moreover, it is connected with the section of fuming, and when the heating core of smoking set inserted from the section of fuming, the tobacco in the section of fuming was blockked to the support segment, can prevent the condition that the tobacco in the section of fuming moved backward, and it is ejecting to avoid in the cigarette bullet ordered thin slice or unordered pipe tobacco to increase the smoke emission volume. The material of the support section includes, but is not limited to, heat-resistant polymer plastic polymers (polyimide PI, polyetheretherketone PEEK, polyamideimide PAI, polybenzimidazole PBI, polyetherimide PEI, polyphenylene sulfide PPS, such as polylactic acid PLA, polysulfone PSU, etc.), paper, non-woven carbon fiber, metal sheet, etc. may be selected as long as it has relatively high stability and does not decompose or melt at a temperature of 350 degrees celsius when used for heating non-combustible cigarette cigarettes.

Further, the number of the intake passages is a positive integer greater than or equal to 2. The channel quantity is more, then it is better to the effect that blocks of tobacco, and the channel quantity is more, and when the flue gas passed through inlet channel, the area of contact of flue gas and support section was bigger, can produce better cooling effect to the flue gas.

Further, the number of the intake passages is 30. And the 30 air inlet channels have the best cooling effect and the best blocking effect on tobacco according to the test.

Further, the maximum interval length of the cross section of the air inlet channel is less than or equal to 0.12 mm. If the maximum interval length of the cross section of the air inlet channel is too large, when the smoking set heating core with a large contact surface is inserted into the smoking section, the tobacco shreds in the smoking section are easily ejected out by the heating core or move backwards into the air inlet channel, so that the air inlet channel is blocked and the heating efficiency is low.

Further, the volumetric hollowness in the cooling support section is greater than or equal to 30%. The volume hollowness is used for measuring the proportion of the hollow part in the whole volume of the support section, namely the proportion of the hollow part in the cooling support section in the total volume of the cooling support section is more than or equal to 30%; the larger volume hollowness can increase the contact area for the flue gas to pass through, and the cooling effect is better.

Further, the volumetric hollowness in the cooling support section is 60%. The 60% hollowness can meet the blocking effect of the cooling support section on the tobacco and can achieve a better smoke cooling effect.

Further, the cross section of the air inlet channel comprises one or more combinations of a circle, a square, a quincunx, a star or an irregular shape.

Further, the cross section of the air inlet channel is circular. The circular channel has larger contact area between the flue gas and the air inlet channel, and better cooling effect.

Further, a cooling section is arranged between the supporting section and the filtering section. The cooling section can further cool down the flue gas through the support section, further avoids the problem of "scalding the mouth".

Another aspect of the present invention is to provide a smoking set for heating a non-burning cigarette, said smoking set being adapted for use with one of the above-mentioned heated non-burning cigarettes; the smoking set comprises a shell and a heating core, wherein a circuit board is arranged in the shell, a control switch and a fixed base are arranged on the shell, the heating core is fixedly connected at the center of the fixed base, the heating core and the control switch are electrically connected with the circuit board, and the cross section of the heating core is of a multi-sheet structure.

When the cigarette heating device is used, the heating core is inserted into a smoking section of a cigarette, the heating core is connected with the circuit board, the heating operation of the heating core is controlled by the control switch, and after the heating core is heated, tobacco in the smoking section is heated to generate smoke for a user to smoke; the cross section of the heating core is of a multi-sheet structure, so that the contact area between the heating core and tobacco can be increased, the smoke release amount of cigarettes can be increased, and the requirements of smokers are met; and because the heating area of the heating core is increased, the heat energy utilization rate in the non-combustion heating process is improved, the smoke release amount is effectively increased, and meanwhile, the heating time of a cigarette can be shortened or the heating temperature of the heating core is reduced, and the phenomenon that the smoke scalds the mouth is effectively inhibited. The smoking set is matched with cigarettes, the area of the heating core of the smoking set is enlarged, the smoking set is matched with the area of the heating core, the cigarette is prevented from being not burnt by the heating of the heating core, the contact area between the heating core and the cigarette is enlarged, the heat energy utilization rate is higher, and the heating volatilization effect on tobacco substance matrixes, smoke agents and the like is more obvious; the cigarette produced by the invention is matched with the smoking set, and the cigarette has a supporting section, so that the smoke can be efficiently cooled, and the condition of mouth burning can be avoided.

Further, the cross section of the heating core is one of a herringbone shape, a cross shape, an S shape, a U shape and two sheet shapes. The heating core with the shapes can enlarge the heating contact area of the heating core to tobacco in the cigarette cartridge, so that the smoke release amount of the cigarette is increased.

Further, the cross section of the heating core is herringbone.

Further, the length of the heating core is 80% of the length of the smoking segment. The length can be kept larger in the heating area of the heating core, and meanwhile, smooth air flow suction is facilitated, so that the heat energy utilization rate is higher, and more sufficient smoke is released.

As a general technical scheme, the invention also provides application of the cigarette which is not burnt by heating in the smoking set for heating the cigarette which is not burnt by heating.

The invention has the beneficial effects that:

1. the cigarette with the heating and non-burning function is provided with the supporting section with the air inlet channel, and the supporting section is matched with the smoking set with the heating core with the multi-sheet structure for use, so that the contact area of the heating core of the smoking set can be increased by 3-5 times compared with the current needle-type or sheet-type heating core, and the defect of insufficient smoke release caused by insufficient heating area at present is fully solved; meanwhile, the cigarette is used for preventing the tobacco shred in the cigarette from being ejected out of the supporting section, the problem that the tobacco shred moves backwards due to the insertion of a large-area heating core can be effectively solved, and the tobacco shred and the heating core are matched for use, so that the utilization rate of heat energy can be obviously improved.

2. The invention increases the heating area of the heating core and improves the heat energy utilization rate in the non-combustion heating process, thereby effectively increasing the smoke release amount, shortening the cigarette heating time or reducing the heating temperature of the heating core when in use, and effectively inhibiting the phenomenon of mouth burning of smoke.

3. The cigarette supporting section without burning during heating simultaneously has the functions of the traditional supporting section and the cooling section, and the structural characteristics are easy to realize and the cost is low during the manufacturing process.

4. The cigarette smoking section can be one or more of reconstituted tobacco in ordered arrangement or a mixture of reconstituted tobacco in disordered arrangement, tobacco shreds and the like, so that the preparation of the smoking section of the cigarette which is not burnt by heating is not limited by the form any more, and the limitation and the cost of cigarette manufacture are reduced.
