一种具有多凹弧形空芯滤棒的空腔式加热卷烟A cavity type heating cigarette with a multi-concave arc hollow filter rod

技术领域technical field

本发明涉及电加热型卷烟，尤其涉及一种具有多凹弧形空芯滤棒的空腔式加热卷烟。The invention relates to an electrically heated cigarette, in particular to a cavity heated cigarette with a multi-concave arc hollow filter rod.

背景技术Background technique

近年来，烟草行业开发出了电加热型卷烟(加热卷烟)。加热卷烟具有发烟材料(或称为发烟剂、气雾形成剂)。当加热卷烟被放入加热器具时，加热器具控制其中的加热元件接通电源而发热，由加热元件对加热卷烟中的发烟材料进行加热，使发烟材料升温至发烟温度，从而产生烟雾来满足用户抽吸需求。加热卷烟在抽吸方式、抽吸体验等方面最接近传统卷烟，且有害成分释放量较少，因此在烟草市场具有很大发展潜力。In recent years, the tobacco industry has developed electrically heated cigarettes (heated cigarettes). Heated cigarettes have a smoking material (or referred to as a smoking agent, aerosol former). When the heated cigarette is put into the heating device, the heating element controlled by the heating device is turned on to generate heat, and the heating element heats the smoking material in the heated cigarette, so that the smoking material is heated to the smoking temperature, thereby generating smoke To meet the user's suction needs. Heated cigarettes are the closest to traditional cigarettes in terms of smoking method and smoking experience, and release less harmful components, so they have great development potential in the tobacco market.

目前的加热卷烟存在如下问题：The current heated cigarettes have the following problems:

1、加热卷烟通常采用四段式或五段式结构，其结构复杂，加工工艺复杂。1. Heated cigarettes usually adopt a four-segment or five-segment structure, which is complex in structure and complex in processing technology.

2、烟气温度较高，消费者抽吸体验差。加热卷烟中的烟草材料在加热器具中通常被加热到250℃至350℃，此温度可使挥发性化学物质充分释放出来。但是，由于加热卷烟烟支长度短，烟支处于加热器具高温包围中，热交换率差，因此入口端烟气温度过高，灼烧感和刺激性明显上升，导致消费者抽吸体验较差。2. The flue gas temperature is high, and the consumer's smoking experience is poor. Tobacco material in heated cigarettes is typically heated in a heating appliance to 250°C to 350°C, a temperature that allows sufficient release of volatile chemicals. However, due to the short length of the heated cigarette, the cigarette is surrounded by the high temperature of the heating device, and the heat exchange rate is poor. Therefore, the temperature of the smoke at the inlet end is too high, and the burning sensation and irritation increase significantly, resulting in a poor smoking experience for consumers. .

3、烟气中烟雾量偏低，消费者体验感和满足感差。加热卷烟抽吸时烟雾量大小受到滤棒的吸阻及过滤效率影响。目前的加热卷烟吸阻较大且过滤效率较高，烟气被滤棒吸附较多，导致烟雾量小，消费者体验感和满足感较差。3. The amount of smoke in the flue gas is low, and the consumer experience and satisfaction are poor. The amount of smoke when smoking a heated cigarette is affected by the suction resistance and filtration efficiency of the filter rod. The current heated cigarettes have large suction resistance and high filtration efficiency, and more smoke is adsorbed by the filter rod, resulting in a small amount of smoke and poor consumer experience and satisfaction.

图1是本发明的一种典型实施例的轴向剖面结构示意图。如图1所示，本发明的加热卷烟包括依次同轴连接的烟草段1、多凹弧形空芯滤棒腔体段2和近唇段3，以及限制所述烟草段1、多凹弧形空芯滤棒腔体段2和近唇段3的外部包裹材料4、5。FIG. 1 is a schematic diagram of an axial cross-sectional structure of a typical embodiment of the present invention. As shown in FIG. 1 , the heated cigarette of the present invention includes a tobacco section 1, a multi-concave arc hollow filterrod cavity section 2 and a near-lip section 3 that are coaxially connected in sequence, and the tobacco section 1, the multi-concave arc confinement Theouter wrapping materials 4 and 5 of thecavity section 2 and thenear lip section 3 of the hollow filter rod.

本发明的加热卷烟包括两个端部：上游端部和下游端部。术语“上游”和“下游”用于关于用户在使用期间对烟支的抽吸方向来描述烟支的各元件或元件的部分的相对位置。在使用中，用户可以对下游端部抽吸，烟支产生的香气以及气雾自上游向下游方向流动，并被吸入用户口中。The heated cigarette of the present invention includes two ends: an upstream end and a downstream end. The terms "upstream" and "downstream" are used to describe the relative positions of elements or portions of elements of a cigarette with respect to the direction in which the user puffs on the cigarette during use. In use, the user can inhale the downstream end, and the aroma and aerosol produced by the cigarette flow from the upstream to the downstream direction, and are sucked into the user's mouth.

多凹弧形空芯滤棒腔体段2设置在烟草段1的相邻下游侧。多凹弧形空芯滤棒腔体段2由多凹弧形空芯滤棒21及包裹其的纸管22构成。多凹弧形空芯滤棒腔体段2的材料优选是经过实践验证的卷烟通用安全材料。优选地，多凹弧形空芯滤棒21包括醋酸纤维丝束和三乙酸甘油酯等，从而对人体是非常安全的。另外，多凹弧形空芯滤棒腔体段2具有较好的降温效果。首先，多凹弧形空芯滤棒腔体段2形成多凹弧形结构，其结构具有降温效果。第二，多凹弧形空芯滤棒腔体段2的醋酸纤维素与三乙酸甘油酯结合后形成的混合材料，材料也可以吸收一定的热量，当来自烟草段1的具有较高的温度(200～350℃)的气雾和香气通过该多凹弧形空芯滤棒腔体段2时，可以起到一定的降温效果，从而在气雾和香气到达使用者的口中时能减少灼烧的感觉或无灼烧感，进一步提升抽吸体验。多凹弧形空芯滤棒表面还可以具有一层成形纸(未图示)。The multi-concave arc-shaped hollow filterrod cavity section 2 is arranged on the adjacent downstream side of the tobacco section 1 . Thecavity section 2 of the multi-concave arc-shaped hollow filter rod is composed of a multi-concave arc-shapedhollow filter rod 21 and apaper tube 22 surrounding it. The material of thecavity section 2 of the multi-concave arc-shaped hollow filter rod is preferably a general safety material for cigarettes that has been proven in practice. Preferably, the multi-concave arc-shapedhollow filter rod 21 includes cellulose acetate tow, triacetin, etc., so that it is very safe for human body. In addition, the multi-concave arc-shaped hollow filterrod cavity section 2 has a better cooling effect. First, the multi-concave arc-shaped hollow filterrod cavity segment 2 forms a multi-concave arc-shaped structure, and the structure has a cooling effect. Second, the mixed material formed by the combination of cellulose acetate and triacetin in thecavity section 2 of the multi-concave arc hollow filter rod can also absorb a certain amount of heat. When the tobacco section 1 has a higher temperature When the aerosol and aroma (200～350℃) pass through the multi-concave arc-shaped hollow filterrod cavity section 2, a certain cooling effect can be achieved, so that the burning can be reduced when the aerosol and aroma reach the user's mouth Burning sensation or no burning sensation further enhances the suction experience. The surface of the multi-concave arc hollow filter rod may also have a layer of forming paper (not shown).

优选地，多凹弧形空芯滤棒腔体段2的纸管22内部的两端分别具有规定长度的空腔。即多凹弧形空芯滤棒21的端面分别与纸管22的对应的端面之间具有规定的长度的两个空腔，包括第一空腔23a和第二空腔23b。该规定长度为在0.5mm～5mm之间。优选地，该规定长度为4mm。通过在纸管22内部两端设置空腔，可以在输送烟气时形成两个缓冲区。具体地，烟气在通过烟草段1后进入该第一空腔23a，在第一空腔23a的区域中经短暂聚集后进入多凹弧形空芯滤棒21，通过多凹弧形空芯滤棒21后再进入第二空腔23b，在第二空腔23b的区域中再次短暂聚集后进入近唇段3。通过在烟气从上游至下游之间设置上述两次缓冲，可以有效地降低烟气温度，使得烟气在到达消费者口腔时减少灼烧感和刺激感。Preferably, both ends of the inside of thepaper tube 22 of the multi-concave arc-shaped hollow filterrod cavity segment 2 respectively have cavities of predetermined lengths. That is, there are two cavities with a predetermined length between the end surfaces of the multi-concave arc-shapedhollow filter rod 21 and the corresponding end surfaces of thepaper tube 22, including thefirst cavity 23a and thesecond cavity 23b. The predetermined length is between 0.5 mm and 5 mm. Preferably, the prescribed length is 4 mm. By arranging cavities at both ends inside thepaper tube 22, two buffer zones can be formed when the flue gas is transported. Specifically, the flue gas enters thefirst cavity 23a after passing through the tobacco section 1, and after a brief accumulation in the area of thefirst cavity 23a, enters the multi-concave arc-shapedhollow filter rod 21, and passes through the multi-concave arc-shaped hollow core Thefilter rod 21 then enters thesecond cavity 23b, gathers briefly again in the region of thesecond cavity 23b, and then enters theproximal lip section 3. FIG. By arranging the above two buffers between the upstream and downstream of the smoke, the temperature of the smoke can be effectively lowered, so that the smoke can reduce burning and irritation when it reaches the mouth of the consumer.

下面结合图2～3详细介绍多凹弧形空芯滤棒21的具体结构。图2是本发明的一种实施例的多凹弧形空芯滤棒的端面示意图；图3是本发明的另一种实施例的多凹弧形空芯滤棒的端面示意图。多凹弧形空芯滤棒21呈空芯柱状，具有轴向贯通的内孔211。该内孔截面形状包括圆形、五角星形和心形等规则形状及其他不规则形状。当所述内孔截面形状为圆形时，圆形直径为1.5mm～3.5mm。当所述内孔截面形状为五角星形或心形时，该形状的外接圆的直径为1.5mm～3.5mm。在一些优选的实施例中，内孔直径可以为2.0mm，2.5mm，3.0mm，3.5mm等。通过设置该轴向的中空结构，可以使得烟气在通过多凹弧形空芯滤棒21的过程中，受到较小的吸阻，能够保证烟气中的烟雾量保持较高的浓度，使得烟气在到达消费者口腔时能够令消费者获得较好的抽吸满足感。The specific structure of the multi-concave archollow filter rod 21 will be described in detail below with reference to FIGS. 2 to 3 . Fig. 2 is a schematic view of an end face of a multi-concave arc-shaped hollow filter rod according to an embodiment of the present invention; Fig. 3 is an end face schematic diagram of a multi-concave arc-shaped hollow filter rod according to another embodiment of the present invention. The multi-concave arc-shapedhollow filter rod 21 is in the shape of a hollow cylinder, and has aninner hole 211 which penetrates in the axial direction. The cross-sectional shape of the inner hole includes regular shapes such as circle, pentagram and heart, and other irregular shapes. When the cross-sectional shape of the inner hole is a circle, the diameter of the circle is 1.5mm˜3.5mm. When the cross-sectional shape of the inner hole is a pentagram or a heart shape, the diameter of the circumscribed circle of the shape is 1.5 mm to 3.5 mm. In some preferred embodiments, the diameter of the inner hole may be 2.0mm, 2.5mm, 3.0mm, 3.5mm, etc. By arranging the axial hollow structure, the flue gas can be subject to less suction resistance in the process of passing through the multi-concave arc-shapedhollow filter rod 21, which can ensure that the amount of smoke in the flue gas maintains a high concentration, so that the When the smoke reaches the consumer's mouth, the consumer can obtain better smoking satisfaction.

进一步地，多凹弧形空芯滤棒21的外表面具有沿滤棒纵向延伸的多个凹陷的弧形槽212。弧形槽212的数量在4～10个之间。优选地，弧形槽212的数量在5～8个之间。在图2所示的实施例中，弧形槽212为在外圆周表面均匀分布的6个凹槽。弧形槽212的槽深在0.5mm～2mm之间，优选地在0.8mm～1.5mm之间。弧形槽212的槽宽在1mm～3mm之间，优选地在1.5mm～2.5mm之间。通过在滤棒21的外表面设置该纵向贯通延伸的弧形槽212，达到进一步减小滤棒的吸阻，保证烟气中的烟雾量保持较高浓度的效果。另外，通过设置弧形槽212,，改变了烟气流动的路径，增加了烟气与空芯滤棒21之间的接触面积，通过该特定的烟气运行路径可起到进一步降温的作用。Further, the outer surface of the multi-concave arc-shapedhollow filter rod 21 has a plurality of concave arc-shapedgrooves 212 extending along the longitudinal direction of the filter rod. The number of arc-shapedgrooves 212 is between 4 and 10. Preferably, the number of arc-shapedgrooves 212 is between 5 and 8. In the embodiment shown in FIG. 2 , the arc-shapedgrooves 212 are 6 grooves evenly distributed on the outer circumferential surface. The groove depth of the arc-shapedgroove 212 is between 0.5 mm and 2 mm, preferably between 0.8 mm and 1.5 mm. The groove width of the arc-shapedgroove 212 is between 1 mm and 3 mm, preferably between 1.5 mm and 2.5 mm. By arranging the longitudinally extending arc-shapedgroove 212 on the outer surface of thefilter rod 21, the suction resistance of the filter rod is further reduced, and the effect of ensuring that the amount of smoke in the flue gas maintains a relatively high concentration is achieved. In addition, by setting thearc groove 212, the flue gas flow path is changed, the contact area between the flue gas and thehollow filter rod 21 is increased, and further cooling can be achieved through the specific flue gas running path.

优选地，多凹弧形空芯滤棒腔体段2的纸管22厚度可以为0.5mm。多凹弧形空芯滤棒腔体段2优选地具有与烟草段1的外径近似相等的外径。Preferably, the thickness of thepaper tube 22 of the multi-concave arc hollow filterrod cavity segment 2 may be 0.5 mm. The multi-concave arc-shaped hollow filterrod cavity segment 2 preferably has an outer diameter approximately equal to that of the tobacco segment 1 .

优选地，多凹弧形空芯滤棒腔体段2具有至少4mm的外径，可以具有在约4mm～约10mm之间的外径，进一步地在约6mm～约8mm之间的外径。在优选实施例中，多凹弧形空芯滤棒腔体段2具有7mm+/-10％的外径。Preferably, the multi-concave arc-shaped hollow filterrod cavity segment 2 has an outer diameter of at least 4 mm, and may have an outer diameter of about 4 mm to about 10 mm, and further an outer diameter of about 6 mm to about 8 mm. In a preferred embodiment, the multi-concave arc-shaped hollow filterrod cavity segment 2 has an outer diameter of 7 mm +/- 10%.

多凹弧形空芯滤棒腔体段2可以具有在约5mm与约30mm之间的长度。在优选实施例中，多凹弧形空芯滤棒腔体段2可以具有约23mm的长度。具体地，多凹弧形空芯滤棒21为15mm，两端的空腔23a、23b分别为4mm。The multi-concave arcuate hollowplug cavity segment 2 may have a length of between about 5 mm and about 30 mm. In a preferred embodiment, the multi-concave arc-shaped hollow filterrod cavity segment 2 may have a length of about 23 mm. Specifically, the multi-concave arc-shapedhollow filter rod 21 is 15 mm, and thecavities 23a and 23b at both ends are respectively 4 mm.

下面详细说明烟草段1的结构。烟草段1可以为烟芯棒，设置在加热卷烟的上游端部，由烟草芯部材料及包裹其的铝箔复合成形纸或防油成形纸构成。具体地，铝箔复合成形纸具有复合层结构，内层为铝箔层，外层为成形纸层，所述内层和外层例如通过粘结剂粘结在一起形成复合层结构。通过在烟草段设置铝箔复合成形纸，可以减少由于发烟材料吸收空气中的水分而导致的外部包裹材料污染和变形。在另外的实施例中，铝箔复合成形纸也可以由防油成形纸替代。The structure of the tobacco segment 1 will be described in detail below. The tobacco section 1 can be a tobacco core rod, which is arranged at the upstream end of the heated cigarette, and is composed of tobacco core material and aluminum foil composite forming paper or oil-proof forming paper wrapped around it. Specifically, the aluminum foil composite forming paper has a composite layer structure, the inner layer is an aluminum foil layer, and the outer layer is a forming paper layer, and the inner layer and the outer layer are bonded together by an adhesive, for example, to form a composite layer structure. By arranging the aluminum foil composite forming paper in the tobacco section, the contamination and deformation of the outer wrapping material caused by the absorption of moisture in the air by the smoking material can be reduced. In another embodiment, the aluminum foil composite forming paper can also be replaced by an oil-proof forming paper.

优选地，烟草段1的烟草芯部材料为再造烟叶材料、原生态烟草材料或涂布的纸质材料。烟草段1经加热后，可以产生气雾和香味，提供抽吸者抽吸普通烟支类似的味道。具体地，烟草段1的芯部由所述再造烟叶材料、原生态烟草材料或涂布的纸质材料切成的多个长条状薄片沿纵向聚集而成。本发明的长条状薄片具有大体平坦的表面。这里的“纵向”表示在烟支的上游端部和下游端部之间的方向。Preferably, the tobacco core material of the tobacco segment 1 is reconstituted tobacco leaf material, virgin tobacco material or coated paper material. After the tobacco segment 1 is heated, it can generate aerosol and aroma, and provide the smoker with a taste similar to that of ordinary cigarettes. Specifically, the core of the tobacco segment 1 is formed by longitudinally gathering a plurality of elongated sheets cut from the reconstituted tobacco leaf material, the raw tobacco material or the coated paper material. The elongated sheet of the present invention has a generally flat surface. "Longitudinal" here means the direction between the upstream end and the downstream end of the cigarette.

烟草段1的芯部由长条状薄片沿烟支纵向聚集而成。术语“薄片”表示该元件具有显著大于其厚度的宽度和长度。术语“聚集”用来描述长条状薄片大体平行于卷烟的纵向轴线聚拢、集合。The core of the tobacco segment 1 is formed by long strips of thin sheets gathered in the longitudinal direction of the cigarette. The term "sheet" means that the element has a width and length that are substantially greater than its thickness. The term "aggregation" is used to describe the aggregation, collection, of the elongated sheets generally parallel to the longitudinal axis of the cigarette.

包括长条状薄片(烟草薄片)的卷烟与包括烟草材料碎片的卷烟相比，能够显著降低烟支端部松散的风险，众所周知端部松散缘于烟支端部的烟草材料碎片的损失。烟支端部松散可能导致烟支与加热器具(烟具)一起使用时加热器具需要频繁清洁，并由此影响加热器具的使用寿命。Cigarettes comprising elongated sheets (tobacco sheets) can significantly reduce the risk of loose ends of cigarettes compared to cigarettes comprising fragments of tobacco material, which are known to result from the loss of fragments of tobacco material at the ends of cigarettes. The loose ends of the cigarettes may cause the heating devices to require frequent cleaning when the cigarettes are used with heating devices (smoking devices), and thus affect the service life of the heating devices.

此外，当加热器具的加热元件插入包括烟草材料碎片的卷烟或者从包括烟草材料碎片的卷烟退出时会引起烟草材料碎片移动，这可能不利地导致需要频繁清洁加热器具的加热元件以去除掉落的烟草碎片。而相反，当加热器具的加热元件插入包括长条状烟草薄片的卷烟或者从包括长条状烟草薄片的卷烟退出时有利地不会引起烟草薄片移动。Furthermore, the movement of the tobacco material fragments when the heating element of the heating appliance is inserted into or withdrawn from the cigarette including the tobacco material fragments may disadvantageously result in the need for frequent cleaning of the heating element of the heating appliance to remove fallen tobacco material fragments. Tobacco fragments. In contrast, the heating element of the heating device advantageously does not cause movement of the tobacco sheet when inserted into or withdrawn from the cigarette comprising the elongated tobacco sheet.

另外，特定长度的长条状薄片的重量由薄片的密度、宽度及厚度决定，因此，特定长度的包括长条状薄片聚集而成的烟草段的卷烟的重量可以通过控制长条状薄片的密度和尺寸而调节，这减小了相同尺寸的卷烟之间重量的不一致性，与包括烟草材料碎片的卷烟相比，降低了重量未在合格范围内的比率。In addition, the weight of the elongated sheet of a specific length is determined by the density, width and thickness of the sheet.
