背景技术Background technique
传统卷烟通过点燃烟丝产生烟气来满足消费者的需求。然而，烟丝燃烧温度一般为900℃左右，燃烧过程中会产生大量含有生物毒性和有害化学成分(如多环芳烃类成分)的烟气，除了危害人类健康之外，还会造成环境污染。研究表明，尼古丁和多数烟草香味成分在较低的温度下(通常低于500℃)就可以转移到烟气中，因此不会产生卷烟因高温燃烧产生的有害物质和侧流烟气，可大幅降低卷烟对人体健康的危害和对环境的污染。最近几十年，世界各大烟草公司都在开发新一代烟草制品或烟草替代品，希望能够在满足消费者需求的基础上最大限度地降低烟草带来的危害。低温卷烟是通过加热(通常低于500℃)而非燃烧烟草，烘烤出烟草中的香味物质来满足消费者的需求，是未来烟草行业的重要发展方向之一。Traditional cigarettes meet consumers' needs by lighting shredded tobacco to produce smoke. However, the burning temperature of shredded tobacco is generally about 900°C. During the burning process, a large amount of smoke containing biological toxicity and harmful chemical components (such as polycyclic aromatic hydrocarbons) will be produced. In addition to endangering human health, it will also cause environmental pollution. Studies have shown that nicotine and most tobacco flavor components can be transferred to the smoke at a relatively low temperature (usually lower than 500 ° C), so there will be no harmful substances and sidestream smoke produced by high-temperature combustion of cigarettes, which can be greatly reduced. Reduce the harm of cigarettes to human health and pollution to the environment. In recent decades, the world's major tobacco companies have been developing a new generation of tobacco products or tobacco substitutes, hoping to minimize the harm caused by tobacco on the basis of meeting consumer needs. Low-temperature cigarettes are heated (usually below 500°C) instead of burning tobacco, and the aroma substances in tobacco are baked to meet the needs of consumers. It is one of the important development directions of the tobacco industry in the future.
目前常用的三种加热方式中，电加热技术相对成熟，使用非常广泛。但一般的电加热通常采用在烟支周围设置加热层的方式，从外向内加热烟草，因此经常会出现外层烟丝已经碳化而内层烟丝还未加热等烟丝加热不均的情况，浪费资源，降低了卷烟的利用率，且吸烟者常感觉烟气有焦糊味道，影响吸烟体验。Among the three commonly used heating methods at present, electric heating technology is relatively mature and widely used. However, general electric heating usually adopts the method of setting a heating layer around the cigarette to heat the tobacco from the outside to the inside. Therefore, it often occurs that the outer layer of shredded tobacco has been carbonized and the inner layer of shredded tobacco has not been heated. The utilization rate of cigarettes is reduced, and smokers often feel that the smoke has a burnt taste, which affects the smoking experience.
此外，为了赋予烟雾各种独特风味，常常需要向烟草制品中添加各种香料。香料泛指任何能够发出香味的物质，在烟草工业中使用的香料一般是能发出香味的天然植物提取物。这些香料在常温或受热时释放出香味成份，混在烟雾中以增香。但实践中发现，香料受热释放香味成份的最佳温度范围，与烟草制品受热释放烟雾的最佳温度范围，往往并不一致。通常，前者要比后者低很多，例如，前者一般在100-200℃范围内，而后者一般在150-300℃范围内，这使得单一加热器很难兼顾二者的最佳工作温度。当使用电加热卷烟加热烟草制品时，为了能够在吸烟者的每次抽吸的短短一两秒内的时间内将烟草制品从环境温度加热至使其充分发烟的发烟温度，通常需要加热器具有较大的加热功率。这带来问题。一是对电源的输出功率要求比较高。二是，在以高加热功率将烟草制品加热至发烟温度过程中，香料常常“过热”，导致其香味“发冲”，香味不够绵软柔和。In addition, in order to impart various unique flavors to the smoke, it is often necessary to add various spices to tobacco products. Spices generally refer to any substance that can emit fragrance. The spices used in the tobacco industry are generally natural plant extracts that can emit fragrance. These spices release aroma components at room temperature or when heated, and are mixed in smoke to enhance aroma. However, it has been found in practice that the optimum temperature range in which spices are heated to release aroma components is often not consistent with the optimum temperature range in which tobacco products are heated to release smoke. Usually, the former is much lower than the latter, for example, the former is generally in the range of 100-200°C, while the latter is generally in the range of 150-300°C, which makes it difficult for a single heater to take into account the optimal operating temperature of both. When using an electrically heated cigarette to heat a tobacco product, in order to be able to heat the tobacco product from ambient temperature to a sufficient smoking temperature within a second or two of each puff of the smoker, it usually requires The heater has a large heating power. This creates problems. First, the output power requirements of the power supply are relatively high. The second is that in the process of heating tobacco products to the smoking temperature with high heating power, the spices are often "overheated", causing their fragrance to "rush", and the fragrance is not soft enough.

The battery segment supplies power to the truncated cone heater and the inner heating sheet through a circuit to heat the tobacco product. The heating temperature is kept below 500°C through the control circuit to realize rapid low-temperature heating.
在优选的实施方案中，其中所述截锥筒加热器33外侧设置圆筒形隔热层36，在所述截锥筒加热器33外侧和所述圆筒形隔热层36内侧之间限定了边腔35，该边腔35内填充有香味产生材料，所述香味产生材料为香料本身或香料与载体的混合物，该边腔与所述混合段4气流连通。所述隔热层36的作用一是隔热以降低外壳的温度，防止吸烟者手指被烫伤，二是其内侧与所述截锥筒加热器33外侧之间限定了上述边腔35。其中香料泛指任何能够散发出香味成份的物质，可以采用烟草工业中常见的任何香料。其中载体可以是多孔载体，用于负载香料；载体也可以与香料以任何合适的形式形成复配物。本发明中，将香料或香料与载体的混合物放在经独特设计的边腔中，实现了香料与烟草制品的分离，则可以根据二者各自的最佳工作温度来设置加热器的功率和工作温度，避免二者工作温度不一致造成香料过热产生香味“过冲”的缺陷。In a preferred embodiment, wherein the outer side of the truncated cone heater 33 is provided with a cylindrical heat insulating layer 36, and the inner side of the cylindrical heat insulating layer 36 is defined between the outer side of the truncated cone heater 33 and the inner side of the cylindrical heat insulating layer 36. A side chamber 35 is provided, which is filled with a fragrance generating material, and the fragrance generating material is the fragrance itself or a mixture of a fragrance and a carrier, and the side chamber is in airflow communication with the mixing section 4 . The function of the heat insulation layer 36 is to insulate the heat to reduce the temperature of the shell and prevent the smoker from being burned on his fingers, and the second is to define the above-mentioned side cavity 35 between its inner side and the outer side of the truncated cone heater 33 . Wherein spices generally refer to any material that can send out flavor components, can adopt any common spices in the tobacco industry. Wherein the carrier may be a porous carrier for loading fragrance; the carrier may also form a complex with the fragrance in any suitable form. In the present invention, the spice or the mixture of the spice and the carrier is placed in the uniquely designed side chamber to realize the separation of the spice and the tobacco product, and the power and working temperature of the heater can be set according to their respective optimal working temperatures. Temperature, to avoid the defect of "overshoot" caused by the overheating of the fragrance caused by the inconsistent working temperature of the two.
所述内加热片固定在截锥筒加热器上，并与截锥筒加热器相连通，同时对烟草制品进行加热。The inner heating sheet is fixed on the truncated cone heater and communicated with the truncated cone heater to heat the tobacco products at the same time.
所述内加热片的厚度为0.5-1.5mm。The thickness of the inner heating sheet is 0.5-1.5mm.
所述截锥筒加热器33与混合段4之间设有干馏器隔板37，该干馏器隔板37上设置有至少一个出气通道38。A retort partition 37 is provided between the truncated cone heater 33 and the mixing section 4 , and at least one gas outlet channel 38 is provided on the retort partition 37 .
所述截锥筒加热器33被设置成能够整体开闭的形式，以便更换各干馏腔中的烟草制品。例如，所述截锥筒加热器33被沿着轴向分为两个半圆筒形部件，两个半圆筒形部件可自如地开启或关闭，例如二者通过卡槽连接或通过转轴连接，等等。The truncated cone heater 33 is configured to be able to be opened and closed as a whole, so as to replace the tobacco products in each retort chamber. For example, the truncated cone heater 33 is divided into two semi-cylindrical parts along the axial direction, and the two semi-cylindrical parts can be opened or closed freely, for example, the two are connected by a slot or a shaft, etc. Wait.
所述截锥筒加热器33侧壁上的侧孔使得在吸烟者的抽吸作用下，一部分烟雾能够进入边腔35，将边腔内香料受热产生的香味成份携带进入混合段4，并在混合段4中与主流烟雾(即沿各个干馏腔行进并穿过干馏器隔板上的出气通道而进入混合段4的烟雾)混合，最终经烟嘴5进入吸烟者口中。通过调节侧孔的数目、香料在边腔内的填充密度和烟草制品在各干馏腔内的填充密度，还可以调节抽吸阻力。边腔的存在为抽吸阻力的调节提供了更丰富的调节方式。在优选的实施方案中，从远离烟嘴端开始，限定每一干馏腔的所述截锥筒加热器33的侧壁上具有数目渐少的侧孔，意外地发现这种设计能使得吸烟者在各次抽吸之间体会到相对更具一致性的抽吸阻力。The side hole on the side wall of the truncated cone heater 33 allows a part of the smoke to enter the side chamber 35 under the smoker's suction, and carry the aroma components produced by the spices in the side chamber into the mixing section 4, and The mixing section 4 is mixed with the mainstream smoke (that is, the smoke that travels along each retort cavity and enters the mixing section 4 through the outlet channels on the partition of the retort), and finally enters the smoker's mouth through the mouthpiece 5 . By adjusting the number of side holes, the filling density of spices in the side chambers and the filling density of tobacco products in each retort chamber, the suction resistance can also be adjusted. The existence of the side cavity provides a richer adjustment method for the adjustment of the suction resistance. In a preferred embodiment, starting from the end away from the mouthpiece, the side walls of the truncated cone heater 33 defining each retort chamber have a decreasing number of side holes, and it has been unexpectedly found that this design enables the smoker to Experience a relatively more consistent draw resistance from puff to puff.
在优选的实施方案中，本发明所述的具有多个干馏腔的电加热型卷烟中的电路设计被设置成使得所述截锥筒加热器33被持续通电发热，且使得所述若干个内加热片31从远离烟嘴的内加热片开始依次通电逐个发热。其中所述截锥筒加热器的发热温度被控制在香料开始释放香味成份的最佳工作温度范围内，但低于烟草制品的发烟温度，而所述内加热片的发热温度被控制在烟草制品的发烟温度以上。由此，截锥筒加热器主要起到加热香料释放香味成份并对各干馏腔内的烟草制品进行预热的作用，而内加热片起到加热发烟的作用。通常，香料开始释放香味成份的温度取决于所使用的香料的类型，而烟草制品的发烟温度的具体数值将取决于所使用的烟草制品的类型。这些可由烟草行业的技术人员容易地根据具体情况而确定。In a preferred embodiment, the circuit design in the electrically heated cigarette with multiple retort chambers according to the present invention is set so that the truncated cone heater 33 is continuously energized to generate heat, and the several internal The heating sheet 31 is energized sequentially from the inner heating sheet far away from the mouthpiece to generate heat one by one. Wherein the heating temperature of the truncated cone heater is controlled within the optimum working temperature range where the spices start to release flavor components, but lower than the smoking temperature of tobacco products, and the heating temperature of the inner heating sheet is controlled within the range of tobacco smoke Above the fuming temperature of the product. Thus, the truncated cone heater mainly functions to heat spices to release aroma components and preheat the tobacco products in each retort chamber, while the inner heating sheet functions to heat and generate smoke. Generally, the temperature at which the flavorant begins to release flavor components depends on the type of flavoring used, and the specific value of the smoking temperature of the tobacco product will depend on the type of tobacco product used. These can be readily determined on a case-by-case basis by those skilled in the tobacco industry.
本发明的有益效果是：The beneficial effects of the present invention are:
本发明中的烟具通过截锥筒加热器对边腔内香料进行加热来释放香味成份并对干馏腔内的烟草制品进行预热，采用多个内加热片依次加热使烟草制品发烟，使得香料和烟草制品实现了独立地加热，能够各自在其最佳工作温度下工作，避免了避免二者工作温度不一致造成香料过热产生香味“过冲”的缺陷。In the smoking set of the present invention, the spices in the side cavity are heated by the truncated cone heater to release the aroma components and preheat the tobacco products in the retort chamber, and a plurality of internal heating plates are used to heat the tobacco products sequentially to make the tobacco products smoke, so that the spices It can be independently heated with tobacco products, and can work at their optimum working temperature, avoiding the defect of "overshoot" caused by the overheating of spices caused by the inconsistency of the two working temperatures.
多个加热片的设计，还避免了传统电加热型卷烟在烟支周围设置加热层从外向内加热烟草时导致的烟草外层过热被烧焦而烟草内部还未充分受热的弊病。The design of multiple heating sheets also avoids the drawbacks of traditional electric heating cigarettes, when a heating layer is set around the cigarette to heat the tobacco from the outside to the inside.
通过调节截锥筒加热器侧孔的数目、香料在边腔内的填充密度和烟草制品在各干馏腔内的填充密度，提供了更丰富的调节抽吸阻力的方式。从远离烟嘴端开始，限定每一干馏腔的所述截锥筒加热器33的侧壁上具有数目渐少的侧孔，能够使各次抽吸时抽吸阻力相对一致。By adjusting the number of side holes of the truncated cone heater, the filling density of spices in the side chambers and the filling density of tobacco products in each retort chamber, more abundant ways of adjusting the suction resistance are provided. Starting from the end away from the mouthpiece, the side walls of the truncated cone heater 33 defining each retort chamber have a decreasing number of side holes, which can make the suction resistance relatively consistent during each puff.

A battery compartment is arranged in the battery section 1 . Both ends of the transition section are threaded, which includes the tobacco baffle and line interface. The heating section 3 consists of a truncated cone heater 33 and inner heating plates 31 perpendicular to the cigarette axis and spaced apart from each other to form a plurality of retort chambers; a cylindrical heat insulating layer 36 is arranged on the outside of the truncated cone heater, A side chamber 35 is defined between the outside of the truncated cone heater 33 and the inside of the cylindrical heat insulating layer 36, and the side chamber 35 is filled with a fragrance generating material, and the fragrance generating material is a spice itself or a fragrance. The side chamber is in gas flow communication with the mixing section 4.
