Description

Technical Field

[0001] The present invention belongs to the field of novel cigarette smoking articles, and in particular relates to a heating smoking article capable of assisting cigarette sealing, and a smoking system and a smoking method comprising the heating smoking article. Background Art

[0002] Traditional cigarettes release nicotine and flavor components in tobacco through combustion to meet the needs of consumers. Heated cigarettes heat tobacco products to atomization temperature through an external heat source to achieve the effect of generating smoke. The heating temperature is lower than the combustion temperature of tobacco, which can significantly reduce the large amount of harmful substances produced by cigarette combustion and reduce the harm of secondhand smoke to non-smokers.

[0003] Since the heating temperature of heated cigarettes is lower than the combustion temperature, compared with traditional cigarettes, the tobacco aroma components of heated cigarettes are difficult to be fully released, and the smoke volume is insufficient, so this type of cigarette is difficult to be accepted by traditional smokers. If the bottom of the cigarette is sealed, the oxygen content will decrease during the heating process (this is due to the replacement of the internal atmosphere by the fresh smoke during the journey). At this time, even if the heating temperature is increased, combustion will not occur, which can increase the release of tobacco aroma components.

[0004] However, if the bottom of the cigarette is sealed during cigarette preparation, it will cause significant changes to the existing cigarette production process and the equipment cost is too high. It is expected to develop a simple and economical method for sealing the bottom of the cigarette.

[0005] The present invention is proposed to solve the above-mentioned problems. Summary of the invention

[0014] Preferably, the circumferential heating tube 404 is made of ceramic or metal tube, and a heating coating is coated on the surface.

[0015] Preferably, the sealing sleeve support seat 406 is a hollow tubular structure, the sealing sleeve 405 is a bowl-shaped structure, and the sealing sleeve support seat 406 at least wraps a portion of the sealing sleeve 405. The sealing sleeve support seat 406 is made of food-grade high-temperature resistant material, such as PEEK, SUS304.

[0016] Preferably, the smoking device further comprises a lower fixing seat 402, which is arranged at the lower end of the cigarette accommodating cavity, and the maximum outer diameter of the sealing sleeve support seat 406 is greater than the minimum inner diameter of the lower fixing seat 402. The material of the upper fixing seat 401 and the lower fixing seat 402 is a high temperature resistant food grade engineering material, such as PEEK.

[0017] The upper fixing seat 401 and the lower fixing seat 402 are used to fix the circumferential heating tube 404 or the heating element.

[0018] Preferably, the smoking device further comprises a vacuum tube 403, which is arranged at the periphery of the cigarette receiving cavity. The vacuum tube 403 is used for heat insulation.

[0019] Preferably, the smoking device further comprises a vacuum tube 403 , which is arranged at the periphery of the circumferential heating tube 404 and is interference fit with the upper fixing seat 401 .

[0020] The second aspect of the present invention provides a smoking system that can assist in sealing a cigarette, comprising the smoking device described in the first aspect and an oxygen-deficient heating cigarette 1;

[0021] The cigarette 1 comprises a tobacco segment 101, a low-resistance segment 102, and a functional filter segment 103 coaxially abutting each other in sequence from upstream to downstream, and the cigarette 1 is wrapped with an external wrapper 4;

[0022] The low absorption resistance section 102 is a tube body having 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;

[0023] A coaxial through hole 4-1 is provided on the outer wrapping member 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 less than the aperture of the side wall through hole 2-2;

[0027] After smoking is completed, the cigarette 1 is pulled out of the cigarette holding chamber. During the pulling-out process, the sealing sleeve 405 and the sealing sleeve support seat 406 move upward with the cigarette 1 in the cigarette holding chamber. When the maximum outer diameter of the sealing sleeve support seat 406 contacts the minimum inner diameter of the inner flange of the upper end of the cigarette holding chamber, the sealing sleeve 405 and the sealing sleeve support seat 406 no longer move upward with the cigarette 1, and the cigarette 1 is completely pulled out.

[0030] The above technical solutions can be freely combined under the premise of no contradiction.

[0031] The present invention has the following beneficial effects:

[0032] 1. The present invention uses for the first time a deformable sealing sleeve and a sealing sleeve support seat combination, which can be movably arranged in the smoke receiving chamber to seal the tobacco section of the cigarette. When the present smoking device is used in conjunction with ordinary cigarettes, it can play a role in fixing the cigarettes and prevent the cigarettes from falling from the cigarette receiving chamber. When the present smoking device is used in conjunction with oxygen-deficient heating cigarettes, the oxygen-deficient heating cigarettes do not need to prepare sealed tobacco sections, which simplifies the preparation process of the cigarettes. In addition, the sealing sleeve and the sealing sleeve support seat are simple in design and easy to industrialize.

[0033] 2. The present invention also designs an oxygen-deficient heating cigarette for use with the smoking device. When smoking a cigarette, the inside of the smoking device is well sealed, and the outside air enters the cigarette from the side wall through holes outside the smoking device, which can reduce the oxygen content, thereby greatly increasing the heating temperature, and the aroma components in the tobacco are released more fully and easily and continuously, and the taste is closer to traditional tobacco, which is more easily accepted by traditional smokers.

[0034] 3. At the same time, during the suction process, the outside air enters from the side wall through-holes. The air flow rate in the low suction resistance section is higher and the pressure is lower, which has an extraction effect on the smoke in the tobacco section. In addition, the outside air also has a cooling effect on the smoke. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The heating assembly 4 includes an upper fixing seat 401, a lower fixing seat 402, a vacuum tube 403, a heating element, a sealing sleeve 405, and a sealing sleeve supporting seat 406.

[0048] The heating element is a circumferential heating tube 404, which is made of a ceramic tube and has a heating coating on its surface.

[0049] The vacuum tube 403 is a tubular structure, located outside the heating element, and is used for heat insulation.

[0050] The upper fixing seat 401 is made of high temperature resistant food grade engineering material peek and is located above the circumferential heating tube 404 in the axial direction of the vacuum tube 403. The maximum outer diameter of the upper fixing seat 401 is greater than the minimum inner diameter of the vacuum tube 403, and the upper fixing seat 401 and the vacuum tube 403 are interference fit.

[0051] The lower fixing seat 402 is made of high temperature resistant food grade engineering material peek and is located below the circumferential heating tube 404 in the axial direction of the vacuum tube 403. The maximum outer diameter of the upper fixing seat 401 is greater than the minimum inner diameter of the vacuum tube 403, and the upper fixing seat 401 and the vacuum tube 403 are interference fit.

[0052] The sealing sleeve 405 is a cylindrical body sealed at one end and has an overall bowl-shaped structure. It is located inside the circumferential heating tube 404 and is made of silicone material. The minimum inner diameter of the sealing sleeve 405 is smaller than the maximum outer diameter of the tobacco segment of the cigarette 1 to ensure that the sealing sleeve 405 can seal the bottom end of the cigarette 1.

[0053] The sealing sleeve support seat 406 is a hollow tubular structure, made of PEEK and integrally connected to the sealing sleeve 405 , integrally connected to the sealing sleeve 405 , disposed outside the sealing sleeve 405 , and movably disposed inside the circumferential heating tube 404 .

This ensures that the sealing sleeve support seat 406 will not be separated from the smoking device. The maximum outer diameter of the sealing sleeve support seat 406 is larger than the minimum inner diameter of the bottom of the lower fixing seat 402 of the heating element, so as to ensure that the sealing sleeve support seat 406 is stuck above the lower fixing seat 402.

[0064] After smoking is completed, the cigarette is pulled out of the cigarette holding chamber. During the pulling-out process, the sealing sleeve 405 and the sealing sleeve support seat 406 move upwards in the cigarette holding chamber along with the cigarette. When the maximum outer diameter of the sealing sleeve support seat 406 contacts the minimum inner diameter of the inner flange of the upper end of the cigarette holding chamber, the sealing sleeve 405 and the sealing sleeve support seat 406 no longer move upwards along with the cigarette, and the cigarette is completely pulled out.

[0065] After the cigarette is completely pulled out, the sealing sleeve 405 returns to its original state and can movably exist in the cigarette accommodating cavity together with the sealing sleeve supporting seat 406.
