Description
Technical Field
The invention relates to the technical field of cigarette products, in particular to a heating non-burning cigarette with a pore structure cooling section.
Background
Because the combustion temperature of the traditional cigarette is above 800 ℃, harmful substances generated by combustion have great harm to non-smoking people, and compared with the traditional cigarette, the low-temperature cigarette can integrally and greatly reduce the release amount of tar and harmful components, so that the low-temperature cigarette is more popular in the market in recent years. The low-temperature cigarette can be transferred into smoke only by heating but not burning tobacco, nicotine and part of tobacco flavor components at a low temperature below 400 ℃. However, the low-temperature cigarette is generally heated by an electric heating appliance, and the distance between the heating area and the cigarette filter tip part is short, so that the problems of smoke overheating and small smoke quantity are easily caused, and the smoking experience is seriously influenced.
In order to solve the problem of overheating of the flue gas, firstly, a thermal barrier material or a structure with a thermal barrier function is adopted, the former is a PLA cooling material to prevent redundant heat from being transferred to the nozzle contact section, and secondly, cold air can directly enter and converge with the flue gas through the mode of punching a through hole at a position suitable for the nozzle contact section, so that the cooling effect is achieved. Practical researches find that the first method utilizes the existing PLA cooling material to have limited cooling effect, and the cooling effect is not ideal due to the fact that the existing PLA cooling material still has overheating performance during suction. The second method must ensure that the total ventilation rate of the cigarettes reaches more than 70% to achieve the cooling effect, but in order to achieve the cooling effect, the cigarettes with too many holes are easy to deform or have the risk of reducing the strength, and the most important is that the smoke can overflow through the through holes to influence the user experience.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a heating non-combustible cigarette with a pore structure cooling section, wherein the pore structure is additionally arranged in the cigarette cooling section, and during smoking, outside cold air enters the cooling section to neutralize smoke, so that the effects of cooling, supplementing smoke and preventing the smoke from overflowing are achieved, and meanwhile, the influence on user experience caused by the leakage of the smoke through a ventilation area can be remarkably reduced or prevented.
In order to solve the technical problems, the invention adopts the technical scheme that:
a heating non-combustible cigarette with a pore structure cooling section comprises a mouth contact section, a cooling section, a disordered tobacco section and tipping paper wrapping the mouth contact section, the cooling section and the disordered tobacco section in sequence, wherein the cooling section is communicated with the disordered tobacco section and the mouth contact section, and smoke generated by the disordered tobacco section passes through the cooling section and enters the mouth contact section for suction; the cooling section is provided with a pore structure for gas to pass through; wrap up in the tipping paper in the cooling section outside and be equipped with at least one ventilation zone that is used for the air business turn over, external cold air passes through the ventilation zone during the suction and gets into pore structure, joins with the flue gas in the cooling section to realize the cooling effect.
Wherein, the outer diameter of the mouth touch section, the cooling section and the disordered tobacco section is consistent. When the cigarette is heated and sucked, the smoke enters the cooling section from the disordered tobacco section and permeates into the pore structure, and meanwhile, due to the change of the suction air pressure, the outside cold air entering from the ventilation area of the tipping paper permeates into the pore structure and is converged with the smoke, so that the effects of cooling and supplementing the smoke are realized. Under the condition of heating and no suction, the tortuous fluid path in the pore structure can effectively prevent the smoke from overflowing outwards, so that the smoke is preserved.
Further, the pore space of the pore structure is 0.02-0.5 mm.
Furthermore, the whole pore structure is in a hollow circular ring shape, the outer wall of the pore structure is attached to the tipping paper in the cooling section area, and the axis of the pore structure is superposed with the axis of the cooling section. As one preferable scheme, the pore structure is located in the cooling section and is a hollow circular structure, namely, the pore structure is in a shape of a pipe body. Part of the flue gas directly enters the mouth contact section through the hollow part of the cooling section, and part of the flue gas also enters the pore structure and enters the mouth contact section from the pore structure. The external cold air is not only converged with the smoke of the pore structure, but also can pass through the pore structure to be converged with the smoke in the middle part, so that the overall neutralization and cooling effects are achieved. From another perspective, the peripheral pore structure also effectively prevents middle flue gas from leaking outwards.
Further, the middle part of the cooling section is also provided with a honeycomb briquette structure, the honeycomb briquette structure is wrapped in a ring of a pore structure, and the head end and the tail end of the honeycomb briquette structure are connected with a nozzle contact section and an unordered tobacco section for direct circulation of smoke. As a preferred scheme, the pore structure is positioned at the periphery of the cooling section, the honeycomb briquette structure is positioned in the middle of the cooling section, and the honeycomb briquette structure is wrapped in the pore structure. Part of the flue gas directly enters the mouth contact section through the through hole of the honeycomb briquette structure, and part of the flue gas also enters the pore structure and enters the mouth contact section from the pore structure. The external cold air is converged with the smoke of the pore structure, so that the effects of local neutralization and cooling are achieved.
Furthermore, the pore structure is integrally cylindrical and is completely filled in the cooling section. As one of them preferred scheme, pore structure fills in the cooling section completely, and all flue gases all get into the mouth from pore structure and touch the section, and the outside cold air converges with pore structure's flue gas, reaches whole neutralization cooling's effect.
Furthermore, an adhesive is adhered between the outer side of the cooling section and the tipping paper, and the adhesive and the ventilation area are staggered. The adhesive is mainly used for adhering and fixing the tipping paper to the cooling section, and the positions of the adhesive and the ventilation area are staggered in order to avoid the influence of the adhesive on the air flow.
Further, the ventilation zone includes a plurality of ventilation holes that are the same in size, the ventilation holes are evenly distributed around the circumference. The size of each vent hole is kept consistent.
Further, the area of the tipping paper provided with the ventilation area is subjected to pre-punching treatment. Tipping paper needs to be subjected to pre-punching treatment before packaging cigarettes, and the corresponding ventilation area is processed, so that the processing difficulty is reduced.
Further, the total ventilation rate of the cigarette is 70% -85%.
The total ventilation of the cigarette is the sum of paper ventilation and mouth ventilation, the total ventilation effect of the cigarette is related to the structure of the cigarette, the cigarette paper, the tipping paper and the tobacco shred structure, and different cigarette structures and different physical filling forms of tobacco sections have influence on the total ventilation rate of the cigarette. Researches find that for heating non-combustible cigarettes, especially thin cigarettes, the total ventilation rate of the cigarettes reaches more than 70 percent to achieve the cooling effect. The choice of mouth ventilation is critical given the physical fill configuration of the tobacco segment and the cigarette paper. If the cooling section is of a compact structure, the cooling section is generally pre-perforated or perforated online, so that cold air enters the cooling section through the tipping paper and is converged with smoke. In order to ensure the total ventilation effect, the number of the punched holes is generally more, and the space selected by the punching position is not large, which is limited by factors of punching equipment, small space left by cigarettes from a heater and the like.
When the cooling section adopts the pore structure, have certain ventilation effect, for guaranteeing total ventilation effect, perhaps only adopt certain air permeability connect dress paper or beat a small amount of holes just can reach the cooling effect, connect the selection scope in the ventilation district of dress paper even just bigger, under the circumstances of guaranteeing good bonding effect, can also set up the ventilation district in a flexible way, realize that production technology, cost, effect, efficiency improve in step.
