Definitions

  • the present disclosure relates to the technical field of smoking device, particularly relates to a smoking system and a smoking article thereof.
  • Electric heating of low-temperature cigarettes is a low-temperature cigarette that produces nicotine smoke by heating tobacco substances with electric power as a heat source.
  • conventional electrically heated low-temperature cigarettes are smoked, the total particulate matter is lower during the initial puffs, but it tends to gradually increase until eventually, giving consumers a feeling of increasing smoke intensity.
  • a conventional cigarette is smoked by a heating chamber in an integrated heating manner, the smoke begins to be extremely weak and then increases rapidly, and then the amount of smoke decreases significantly as the number of suctions increases. This is mainly because it utilizes the previous puffs to reach the optimum temperature, so that the tobacco article produces a high concentration of aerosol, however, as the smoking progresses, the aerosol is depleted.
  • the released amount of smoke is uncontrollable, the sensory differences between the different number of suctions are large, and the sensory characteristics tend to be weakened in the late stage of smoking.
  • a smoking article includes a mouthpiece and a cigarette rod. One end of the cigarette rod is connected to the mouthpiece.
  • the cigarette rod includes a plurality of tobacco segments connected sequentially.
  • the tobacco segment includes a tobacco material and a phase change material disposed in the tobacco material.
  • a smoking system includes a smoking device and the smoking article.
  • the smoking device includes a heating pot.
  • the heating pot includes a plurality of heating elements connected sequentially. Each of the heating elements is provided with a heating chamber.
  • the heating chambers of the plurality of heating elements form an accommodating chamber configured to accommodate the smoking article.
  • the plurality of heating elements independently control temperature and heat sequentially in a direction from the insertion opening towards the air inlet hole.
  • the cigarette rod is inserted into the accommodating chamber, and the plurality of tobacco segments are in one-to-one correspondence with the plurality of heating elements.
  • a smoking system 10 includes a smoking device 100 and a smoking article 200.
  • the smoking device 100 is used to heat the smoking article 200.
  • the smoking device 100 heats the smoking article 200 within a certain temperature range and controls the smoking article 200 to be non-combusting, so that the nicotine and part of the tobacco flavor constituent can be transferred to the smoke for smoking, which can greatly reduce the released amount of tar and harmful constituents.
  • the smoking device 100 includes a housing 120 and a heating pot 140.
  • the housing 120 is provided with a receiving chamber and an air inlet 122 in communication with the receiving chamber.
  • the heating pot 140 is disposed in the receiving chamber.
  • the heating pot 140 includes a plurality of heating elements 142 that are sequentially connected.
  • the heating element 142 can be a ceramic structure provided with a heating circuit. There may be 2 to 15 heating elements 142.
  • Each of the heating elements 142 is provided with a heating chamber 142a, and the heating chambers 142a of the plurality of heating elements 142 form an accommodating chamber 144 for accommodating the smoking article 200.
  • Both ends of the accommodating chamber 144 are provided with an insertion opening 146 for inserting the smoking article 200 and an air inlet hole 148 in communication with the air inlet 122, respectively.
  • the plurality of heating elements 142 independently control temperature and sequentially heat the smoking article 200 in a direction from the insertion opening 146 towards the air inlet hole 148.
  • the smoking article 200 includes a mouthpiece 240 and a cigarette rod 220.
  • the mouthpiece 240 may be a filter.
  • One end of the cigarette rod 220 is connected to the mouthpiece 240.
  • the cigarette rod 220 includes a plurality of tobacco segments 242 that are sequentially connected.
  • the tobacco segment 242 includes a tobacco material 244 and a phase change material 246 disposed in the tobacco material 244.
  • the cigarette rod 220 can be inserted into the accommodating chamber 144, and the plurality of tobacco segments 242 are in one-to-one correspondence with the plurality of heating elements 142.
  • the plurality of tobacco segments 242 of the smoking article 200 in cooperation with the heating pot 140 having the plurality of heating elements 142 independently controlling temperature, facilitates controlling the temperature of the different tobacco segments 242. Since the plurality of heating elements 142 independently control the temperature and sequentially heat from the insertion opening 146 towards the air inlet hole 148, the plurality of tobacco segments 242 of the smoking article 200 may be sequentially heated in a direction from one end adjacent to the mouthpiece 240 towards the other end away from the mouthpiece 240. The high-concentration aerosol produced during the overall heating is avoided, and the released amount of smoke during the smoking process is relatively uniform, thereby balancing the sensory difference between the different number of suctions and improving the consistency of the smoke taste. Since the phase change material 246 absorbs or releases a large amount of heat during a phase change process, it is possible to delay the heating and cooling and prevent the temperature from increasing or decreasing too fast, thereby better controlling the temperature of the smoking article 200.
  • the heating sequence of the heating pot 140 to the smoking article 200 is reversed from that of the present embodiment, that is, the smoking article 200 is sequentially heated in a direction from the smoking article 200 towards the mouthpiece 240, since the gas stream flowing through the heated tobacco segment 242 has a higher temperature, the gas stream heats the tobacco segment 242 that flows later, resulting in a part of the smoke constituent in the unheated tobacco segment 242 being sublimated or the smoke constituent having a lower decomposition temperature being released. Therefore, the part of the smoke constituent in the tobacco segment 242 heated later is passed away in advance, resulting in inconsistent smoke taste when the different tobacco segments 242 are heated.
  • heating the unheated portion of the cigarette too early may result in the generation of a part of smoke or the thermal degradation of the portion of the cigarette due to heat, thereby changing its own quality. Reheating the previously heated portion may result in an unpleasant odor or harmful constituent.
  • the heated gas stream in a manner from one end adjacent to the mouthpiece 240 towards the other end away from the mouthpiece 240, the heated gas stream can be prevented from flowing through the unheated tobacco segment 242, thereby avoiding the aforementioned problems of inconsistencies in the smoke taste and causing unpleasant odor or harmful constituents.
  • the smoking article 200 further includes a heat insulation layer 260 located between two adjacent tobacco segments 242 to avoid heat conduction and interaction between the tobacco segments 242.
  • the heat insulation layer 260 may also be located between the mouthpiece 240 and the tobacco segment 242 connected to the mouthpiece 240 to prevent heat from being conducted to the mouthpiece 240.
  • the adjacent tobacco segments 242 may be directly connected without providing the heat insulation layer 260, which can also achieve the effect of increasing the consistency of the smoke taste and prevent the temperature from increasing or decreasing too fast.
  • the phase change material 246 includes a solid-solid phase change material and a solid-liquid phase change material, and the phase change material 246 has a phase change temperature of 200 °C to 500 °C, preferably 240 °C to 350 °C.
