本申请要求于2022年10月12日提交中国专利局、申请号为202211247715.8、发明名称为“一种加热卷烟的烟支及加热卷烟的烟支打孔方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。This application claims the priority of the Chinese patent application filed with the China Patent Office on October 12, 2022, with application number 202211247715.8 and invention name "A heated cigarette and a method for punching a heated cigarette", all contents of which are incorporated by reference into this application.

技术领域Technical Field

本申请涉及新型烟草制品技术领域，特别涉及一种加热卷烟的烟支及加热卷烟的烟支打孔方法。The present application relates to the technical field of novel tobacco products, and in particular to a heated cigarette and a method for punching a heated cigarette.

背景技术Background technique

加热卷烟作为一种新型烟草制品，因其避免了烟草高温燃烧导致的焦油和大量有害化合物生成，从而具有可以降低烟气有害化学成分和生物毒性等特点，成为了烟草行业主要研究方向。As a new type of tobacco product, heated cigarettes have become a major research direction in the tobacco industry because they avoid the production of tar and a large number of harmful compounds caused by high-temperature combustion of tobacco, thereby reducing the harmful chemical components and biological toxicity of smoke.

加热卷烟通常包括加热烟具及烟支，在品吸时，将烟支的烟草段***加热烟具的加热腔中，通过加热腔中设置的加热件对烟支的烟草段进行加热。加热卷烟的烟支产生的烟气虽然本身温度较传统卷烟低，但由于烟气含水量较高，烟气通路较短，到达口腔的主流烟气感官温度较传统卷烟高，因此加热卷烟的烟支需具有对烟气进行降温的功能。目前是通过在加热卷烟的烟支上开设有气孔，从而通过气孔引入冷空气实现对烟气进行冷却降温。Heated cigarettes usually include heated smoking utensils and cigarettes. When smoking, the tobacco segment of the cigarette is inserted into the heating chamber of the heated smoking utensils, and the tobacco segment of the cigarette is heated by the heating element provided in the heating chamber. Although the temperature of the smoke generated by heated cigarettes is lower than that of traditional cigarettes, the smoke has a higher water content and a shorter smoke path, and the sensory temperature of the mainstream smoke reaching the oral cavity is higher than that of traditional cigarettes. Therefore, heated cigarettes need to have the function of cooling the smoke. At present, the smoke is cooled by opening air holes on the heated cigarettes, and then introducing cold air through the air holes.

然而，现有技术中的加热卷烟的烟支按照直径规格的不同，通常可以分为直径大于7mm的烟支以及直径在5-7mm之间的烟支。直径在5-7mm之间的烟支由于其直径更小，使得烟支的雾化烟气温度更高，也使得烟支的降温压力较大，在烟支上的开设的气孔数一般远多于直径大于7mm的烟支。而过多的开孔数和过小的圆周极易导致5-7mm烟支在使用过程中受力折断，影响烟支的正常品吸。However, the heated cigarettes in the prior art can be generally divided into cigarettes with a diameter greater than 7 mm and cigarettes with a diameter between 5-7 mm according to different diameter specifications. Cigarettes with a diameter between 5-7 mm have a smaller diameter, which makes the atomized smoke temperature of the cigarette higher and also makes the cooling pressure of the cigarette greater. The number of pores opened on the cigarette is generally much more than that of cigarettes with a diameter greater than 7 mm. However, too many openings and too small circumferences can easily cause 5-7 mm cigarettes to break under force during use, affecting the normal smoking of the cigarettes.

本发明提供了一种加热卷烟的烟支，所述烟支的直径在5-7mm之间，所述烟支上开设有气孔，所述气孔沿所述烟支的径向贯穿所述烟支；其中，所述气孔由气孔单元构成，且至少一个所述气孔为复合气孔，所述复合气孔至少由两所述气孔单元部分重合构成。由于所述加热卷烟的烟支上开设的所述气孔中，至少有一个是所述复合气孔，而所述复合气孔由两所述气孔单元部分重合构成，从而增加了单个所述气孔的孔道容积，让单个所述气孔能引入更多的冷空气，增加了单个所述气孔的冷却降温效果，这样使得所述加热卷烟的烟支上所需开设的所述气孔数量更少，尽可能的避免了所述气孔对所述加热卷烟的烟支的强度的影响，让所述加热卷烟的烟支在使用过程中不容易受力折断，保障所述加热卷烟的烟支的正常品吸。The present invention provides a heated cigarette, wherein the diameter of the cigarette is between 5 and 7 mm, and the cigarette is provided with pores, and the pores penetrate the cigarette in the radial direction of the cigarette; wherein the pores are composed of pore units, and at least one of the pores is a composite pore, and the composite pore is composed of at least two pore units partially overlapping. Since at least one of the pores opened on the heated cigarette is a composite pore, and the composite pore is composed of two pore units partially overlapping, the pore volume of a single pore is increased, so that a single pore can introduce more cold air, and the cooling effect of a single pore is increased, so that the number of pores required to be opened on the heated cigarette is reduced, and the influence of the pores on the strength of the heated cigarette is avoided as much as possible, so that the heated cigarette is not easily broken by force during use, and the normal smoking of the heated cigarette is guaranteed.

请结合参阅图1。本实施例提供了一种加热卷烟的烟支100，所述烟支100的直径在5-7mm之间。Please refer to Figure 1. This embodiment provides a heated cigarette stick 100, wherein the diameter of the cigarette stick 100 is between 5 and 7 mm.

所述烟支100上开设有气孔10，所述气孔10沿所述烟支100的径向贯穿所述烟支100。所述气孔10由气孔单元20构成，且至少一个所述气孔10为复合气孔30，所述复合气孔30至少由两所述气孔单元20部分重合构成。其中部分重合指的是：两所述气孔单元20之间相互连通，且两所述气孔单元20没有完全重合。从而使得所述复合气孔30的容积相较于单一的所述气孔单元20更大，同时所述复合气孔30在所述烟支100中所需占用的空间又相较于单独的两个所述气孔单元20而言又更少。The cigarette 100 is provided with pores 10, and the pores 10 penetrate the cigarette 100 in the radial direction of the cigarette 100. The pores 10 are composed of pore units 20, and at least one of the pores 10 is a composite pore 30, and the composite pore 30 is composed of at least two pore units 20 partially overlapping. Partial overlap means that the two pore units 20 are interconnected, and the two pore units 20 do not completely overlap. As a result, the volume of the composite pore 30 is larger than that of a single pore unit 20, and the space occupied by the composite pore 30 in the cigarette 100 is less than that of two separate pore units 20.

也就是说，所述烟支100上至少开设有一个所述气孔10，且开设的所述气孔10当中至少有一个所述气孔10为所述复合气孔30。由于所述复合气孔30为至少两个所述气孔单元20构成，使得所述烟支100上所需开设的所述气孔10的数量可以更少，这样在保障了降温效果的前提下又能尽可能的避免所述气孔10对所述烟支100结构强度的影响，让所述烟支100在使用过程中不容易受力折断，更好的保障了所述烟支100的正常品吸。 That is to say, at least one of the pores 10 is provided on the cigarette 100, and at least one of the pores 10 is a composite pore 30. Since the composite pore 30 is composed of at least two pore units 20, the number of pores 10 required to be provided on the cigarette 100 can be reduced, so that the influence of the pores 10 on the structural strength of the cigarette 100 can be avoided as much as possible while ensuring the cooling effect, so that the cigarette 100 is not easily broken by force during use, and the normal smoking of the cigarette 100 is better guaranteed.

可以理解的是，所述复合气孔30中两所述气孔单元20之间重合区域的大小，会影响到所述复合气孔30的通风效果。如图2所示当两所述气孔单元20之间重合区域较少时，所述复合气孔30的通风面积相对较大。如图3所示当两所述气孔单元20之间重合区域较多时，所述复合气孔30的通风面积相对较小。并且，如图4所示所述复合气孔30中所包含的所述气孔单元20的数量也同样能影响所述复合气孔30的通风面积。从而，根据实际所需的通风率，可以适当的对所述复合气孔30进行调节，如调节各所述气孔单元20之间的重合区域大小、所述气孔单元20的设置数量等。It is understandable that the size of the overlapping area between the two pore units 20 in the composite pore 30 will affect the ventilation effect of the composite pore 30. As shown in FIG. 2, when the overlapping area between the two pore units 20 is small, the ventilation area of the composite pore 30 is relatively large. As shown in FIG. 3, when the overlapping area between the two pore units 20 is large, the ventilation area of the composite pore 30 is relatively small. Moreover, as shown in FIG. 4, the number of the pore units 20 included in the composite pore 30 can also affect the ventilation area of the composite pore 30. Therefore, according to the actual required ventilation rate, the composite pore 30 can be appropriately adjusted, such as adjusting the size of the overlapping area between each pore unit 20, the number of pore units 20, etc.

可以理解的是，在加热卷烟领域，加热卷烟的烟支产生的烟气虽然本身温度较传统卷烟低，但由于烟气含水量较高，烟气通路较短，到达口腔的主流烟气感官温度较传统卷烟高，因此加热卷烟的烟支需具有对烟气进行降温的功能。目前是通过在加热卷烟的烟支上开设有气孔，从而通过气孔引入冷空气实现对烟气进行冷却降温。而加热卷烟的烟支按照直径规格的不同，通常可以分为直径大于7mm的烟支以及直径在5-7mm之间的烟支。直径在5-7mm之间的烟支，其雾化烟气温度更高，且在滤棒中使用结构或材料降温操作空间过小，故现有技术中一般采用在线打孔方式引入外界冷空气中和高温烟气温度。同时直径在5-7mm之间的烟支降温压力较大，在滤棒上的开孔数一般远多于直径大于7mm的烟支(往往在10、15以上)，过多的开孔数和过小的圆周极易导致烟支在使用过程中受力折断。It is understandable that in the field of heated cigarettes, although the temperature of the smoke produced by heated cigarettes is lower than that of traditional cigarettes, the smoke has a higher water content and a shorter smoke path, and the sensory temperature of the mainstream smoke reaching the oral cavity is higher than that of traditional cigarettes. Therefore, heated cigarettes need to have the function of cooling the smoke. At present, the smoke is cooled by opening pores on the heated cigarettes, and then introducing cold air through the pores. According to the different diameter specifications, heated cigarettes can generally be divided into cigarettes with a diameter greater than 7mm and cigarettes with a diameter between 5-7mm. The atomized smoke temperature of cigarettes with a diameter between 5-7mm is higher, and the cooling operation space using the structure or material in the filter rod is too small. Therefore, the prior art generally adopts an online punching method to introduce external cold air to neutralize the high temperature smoke temperature. At the same time, cigarettes with a diameter between 5-7mm have greater cooling pressure, and the number of holes on the filter rod is generally much more than that of cigarettes with a diameter greater than 7mm (often more than 10 or 15). Too many holes and too small circumference can easily cause the cigarette to break under force during use.

与此同时，申请人研究发现，由于直径在5-7mm之间的烟支的雾化烟气多使用***加热(内芯)，导致滤棒中同一轴向位置的烟气温度呈现外高内低的现象，打孔的引入更易使气态水分、甘油与外界冷空气高温差混合，促进成核雾化，故在滤棒上一定区间内进行打孔还具有提升烟气浓度的效应。At the same time, the applicant's research found that since the atomized smoke of cigarettes with a diameter between 5-7mm mostly uses peripheral heating (inner core), the smoke temperature at the same axial position in the filter rod is high outside and low inside. The introduction of perforations makes it easier for gaseous moisture and glycerin to mix with the high temperature difference of external cold air, promoting nucleation atomization. Therefore, perforating within a certain interval on the filter rod also has the effect of increasing the smoke concentration.

而本实施例提供的所述烟支100中，在所述烟支100上开设有所述复合气孔30，从而可以增加单个气孔的孔道容积，让单个气孔能引入更多的冷空气，从而可以更好的调节烟气温度和浓度，这样也使得所述烟支100上所需开设的所述气孔10的总量更少，尽可能的避免了开设的所述气孔10对所述烟支100的结构强度的影响，让所述烟支100在使用过程中不容易受力折断，更好的保障了所述烟支100的正常品吸。In the cigarette 100 provided in this embodiment, the composite air hole 30 is provided on the cigarette 100, so that the channel volume of a single air hole can be increased, so that a single air hole can introduce more cold air, so that the smoke temperature and concentration can be better adjusted. In this way, the total number of the air holes 10 required to be opened on the cigarette 100 is reduced, and the influence of the opened air holes 10 on the structural strength of the cigarette 100 is avoided as much as possible, so that the cigarette 100 is not easily damaged during use. It is easy to break under force, which better ensures the normal smoking of the cigarette 100.

需要说明的是，现有技术中对烟支进行打孔是采用的激光打孔设备，激光打孔设备一次只能在烟支上成型一个气孔单元。具体而言，以目前的烟支打孔工艺而言，在烟支上一次打孔只能形成一个小圆孔。即在本实施例中，所述气孔单元20为圆孔。It should be noted that in the prior art, laser punching equipment is used to punch holes in cigarettes, and laser punching equipment can only form one pore unit on a cigarette at a time. Specifically, with the current cigarette punching process, only a small round hole can be formed on a cigarette at a time. That is, in this embodiment, the pore unit 20 is a round hole.

例如：现有技术中若需要在烟支上开设10个气孔时，则是通过激光打孔设备在烟支上成型10个相互间隔的气孔单元，一个气孔单元构成一个气孔，从而在烟支上形成10个气孔。For example, in the prior art, if 10 pores need to be opened on a cigarette, 10 mutually spaced pore units are formed on the cigarette by laser punching equipment, and one pore unit constitutes one pore, thereby forming 10 pores on the cigarette.

而本实施例提供的所述烟支100中，由于所述气孔10至少一个为所述复合气孔30，那么所述烟支100所需开设的所述气孔10的总量可以小于10个气孔。例如：当所述烟支100上设置的所述气孔10中有一个为所述复合气孔30，并且所述复合气孔30由两个所述气孔单元20构成时，那么所述烟支100上所需开设的所述气孔10总量则可以为9个。9个所述气孔10中，1个为所述复合气孔30，另外8个为普通的所述气孔10，普通的所述气孔10则由一个所述气孔单元20构成。而当所述复合气孔30由三个或三个以上所述气孔单元20构成时，那么所述烟支100上所需开设的所述气孔10的总量可以更少。同理，当所述复合气孔30设置的数量越多，同样也能降低所述烟支100上所需开设的所述气孔10的总量，例如：当所述烟支100上开设的所述气孔10全部为所述复合气孔30时，那么所述烟支100上所需开设的气孔10总量则可进一步的减少。需要说明的是，上述所述气孔10的设置数量以及所述复合气孔30的设置数量仅为举例而言，所述烟支100上所设置所述气孔10的数量以及所述气孔10的类型可根据实际需求进行相应的选择，只需设置有所述复合气孔30，从而可以更好的调节烟气的温度和浓度，更好的保障所述烟支100的结构强度，让所述烟支100不容易受力折断即可。In the cigarette 100 provided in the present embodiment, since at least one of the pores 10 is the composite pore 30, the total number of pores 10 required to be opened in the cigarette 100 may be less than 10 pores. For example, when one of the pores 10 provided on the cigarette 100 is the composite pore 30, and the composite pore 30 is composed of two pore units 20, the total number of pores 10 required to be opened in the cigarette 100 may be 9. Among the 9 pores 10, 1 is the composite pore 30, and the other 8 are ordinary pores 10, and the ordinary pores 10 are composed of one pore unit 20. When the composite pore 30 is composed of three or more pore units 20, the total number of pores 10 required to be opened in the cigarette 100 may be even less. Similarly, when the number of the composite pores 30 is increased, the total number of the pores 10 required to be opened on the cigarette 100 can also be reduced. For example, when all the pores 10 opened on the cigarette 100 are the composite pores 30, the total number of the pores 10 required to be opened on the cigarette 100 can be further reduced. It should be noted that the number of the pores 10 and the number of the composite pores 30 are only for example. The number of the pores 10 and the type of the pores 10 set on the cigarette 100 can be selected accordingly according to actual needs. It is only necessary to set the composite pores 30 so as to better adjust the temperature and concentration of the smoke, better ensure the structural strength of the cigarette 100, and make the cigarette 100 not easily broken by force.

优选的，所述烟支100上开设有多个所述气孔10，且所述烟支100上开设的所有所述气孔10均为所述复合气孔30。从而更好的保障了开设于所述烟支100上单个的所述气孔10的冷却降温效果，并且也能让所述烟支100上所需开设的气孔10更少。 Preferably, the cigarette 100 is provided with a plurality of pores 10, and all the pores 10 provided on the cigarette 100 are the composite pores 30. This better ensures the cooling effect of the single pore 10 provided on the cigarette 100, and also reduces the number of pores 10 required on the cigarette 100.

优选的，沿所述烟支100上所述复合气孔30的打孔方向，位于首部的所述复合气孔30与位于尾部的所述复合气孔30形状结构相同，位于首部的所述复合气孔30与尾部的所述复合气孔30之间的所述复合气孔30形状结构相同。即沿着所述烟支100上多个所述复合气孔30的开设方向(在本实施例中为沿所述烟支100的周向依次开设)，打孔时，第一个开设的所述复合气孔30的形状结构与最后一个开设的所述复合气孔30的形状结构相同。也就是说，在一种实施例中，所述复合气孔30开设数量不少于3个，且位于首部以及尾部的两个所述复合气孔30中包含的所述气孔单元20的数量相同，并且每个所述复合气孔30中的所述气孔单元20之间重合部分相同，这样使得所述烟支100上开设的所有所述复合气孔30均为同一结构形状。并且，位于首部的所述复合气孔30与尾部的所述复合气孔30之间的所有其他的所述复合气孔30形状结构相同。例如，当所述烟支100上开设有4个所述复合气孔30时，则位于首部与尾部的两个所述复合气孔30的形状结构相同，而其他的两个所述复合气孔30的形状结构相同，这样可以更好的保障了各个所述气孔10通风率的平衡。而在其他实施例中，当所述复合气孔30仅开设有两个时，即仅包括首部的所述复合气孔30和尾部的所述复合气孔30时，可让两个所述复合气孔30的形状结构相同。Preferably, along the punching direction of the composite pores 30 on the cigarette 100, the composite pores 30 located at the head and the composite pores 30 located at the tail have the same shape and structure, and the composite pores 30 located at the head and the composite pores 30 at the tail have the same shape and structure. That is, along the opening direction of the multiple composite pores 30 on the cigarette 100 (in this embodiment, they are opened in sequence along the circumference of the cigarette 100), when punching, the shape and structure of the first composite pore 30 opened is the same as the shape and structure of the last composite pore 30 opened. That is, in one embodiment, the number of composite pores 30 opened is not less than 3, and the number of pore units 20 contained in the two composite pores 30 located at the head and the tail is the same, and the overlapped parts between the pore units 20 in each composite pore 30 are the same, so that all the composite pores 30 opened on the cigarette 100 have the same structural shape. Furthermore, all other composite air holes 30 between the composite air holes 30 at the head and the composite air holes 30 at the tail are of the same shape and structure. For example, when the cigarette 100 is provided with four composite air holes 30, the two composite air holes 30 at the head and the tail are of the same shape and structure, and the other two composite air holes 30 are of the same shape and structure, which can better ensure the balance of ventilation rates of each air hole 10. In other embodiments, when there are only two composite air holes 30, that is, only the composite air holes 30 at the head and the composite air holes 30 at the tail, the two composite air holes 30 can have the same shape and structure.

优选的，所有所述气孔10沿所述烟支100的周向等间距分布。即所述烟支100上开设的所述气孔10沿所述烟支100的周向依次间隔分布，且沿所述烟支100的周向，相邻的两个所述气孔10之间的间距相等，从而更好的实现调节所述烟支100的烟气温度和浓度。Preferably, all the air holes 10 are evenly spaced along the circumference of the cigarette 100. That is, the air holes 10 opened on the cigarette 100 are spaced in sequence along the circumference of the cigarette 100, and the distance between two adjacent air holes 10 along the circumference of the cigarette 100 is equal, so as to better adjust the smoke temperature and concentration of the cigarette 100.

优选的，所有所述气孔单元20的中心位于同一平面上，且该平面垂直于所述烟支100轴线。即在本实施例中，所有所述气孔10位于所述烟支100上的同一轴向位置，且所述复合气孔30中的所述气孔单元20沿所述烟支100的周向延伸设置，这样，让每个所述气孔单元20的中心位于所述烟支100上的同一轴向位置。也就是说，在本实施例中，所有所述气孔10呈环状分布在所述烟支100上，这样进一步的保障了所述气孔10对所述烟支100的烟气温度和浓度的效果。需要说明的是，在本实施例中，所述烟支100上设有一组所述气孔10组，所述气孔10组中的所有所述气孔10 分布于所述烟支100上的同一轴向位置。当然，在其他实施例中，所述烟支100上还可开设更多组所述气孔10组，如所述气孔10组可设置两组，同一组所述气孔10组中的所述气孔10均同一轴向位置，且两组所述气孔10组沿所述烟支100的轴向相互间隔。也就是说，在本实施例中，所述烟支100上的打孔排数为单排。在其他实施例中，所述烟支100上的打孔排数还可为双排或更多。Preferably, the centers of all the pore units 20 are located on the same plane, and the plane is perpendicular to the axis of the cigarette 100. That is, in this embodiment, all the pores 10 are located at the same axial position on the cigarette 100, and the pore units 20 in the composite pores 30 are arranged along the circumferential extension of the cigarette 100, so that the center of each of the pore units 20 is located at the same axial position on the cigarette 100. That is to say, in this embodiment, all the pores 10 are distributed in a ring shape on the cigarette 100, which further ensures the effect of the pores 10 on the smoke temperature and concentration of the cigarette 100. It should be noted that, in this embodiment, a group of pores 10 is provided on the cigarette 100, and all the pores 10 in the pore 10 group The air holes 10 are distributed at the same axial position on the cigarette 100. Of course, in other embodiments, more groups of the air holes 10 can be provided on the cigarette 100, such as two groups of the air holes 10, the air holes 10 in the same group of the air holes 10 are all at the same axial position, and the two groups of the air holes 10 are spaced apart from each other along the axial direction of the cigarette 100. That is, in this embodiment, the number of rows of holes on the cigarette 100 is a single row. In other embodiments, the number of rows of holes on the cigarette 100 can also be double rows or more.

优选的，在一种实施例中，所述烟支100的直径为6-7mm，所述烟支100上开设的所述气孔10的数量不多于8，从而更好的保障了所述烟支100的结构强度。Preferably, in one embodiment, the diameter of the cigarette 100 is 6-7 mm, and the number of the air holes 10 provided on the cigarette 100 is no more than 8, thereby better ensuring the structural strength of the cigarette 100.

优选的，在一种实施例中，所述烟支100的直径为5-6mm，所述烟支100上开设的所述气孔10的数量不多于6，从而更好的保障了所述烟支100的结构强度。Preferably, in one embodiment, the diameter of the cigarette 100 is 5-6 mm, and the number of the air holes 10 provided on the cigarette 100 is no more than 6, thereby better ensuring the structural strength of the cigarette 100.

优选的，所述烟支100包括烟草段40及与所述烟草段40连接的滤棒段50，所述气孔10开设于所述滤棒段50。其中，所述烟草段40指的是包覆有薄片或烟草物质的部分，在加热卷烟使用时，所述烟草段40对应的***加热烟具的加热腔中，而所述滤棒段50则是所述烟支100***加热烟具后未被加热腔覆盖的部分。具体的，所述滤棒段50包括但不限于其中的纸管段、中空醋纤段。这样，在所述烟支100上开设的所述气孔10也不会影响到所述烟支100的正常品吸。Preferably, the cigarette 100 includes a tobacco segment 40 and a filter rod segment 50 connected to the tobacco segment 40, and the air hole 10 is opened in the filter rod segment 50. The tobacco segment 40 refers to the part covered with a thin sheet or tobacco material. When the heated cigarette is used, the tobacco segment 40 is correspondingly inserted into the heating cavity of the heated tobacco device, and the filter rod segment 50 is the part of the cigarette 100 that is not covered by the heating cavity after the cigarette 100 is inserted into the heated tobacco device. Specifically, the filter rod segment 50 includes but is not limited to the paper tube segment and the hollow acetate fiber segment. In this way, the air hole 10 opened on the cigarette 100 will not affect the normal smoking of the cigarette 100.

本实施例提供的所述加热卷烟的烟支100将多个所述气孔单元20部分重合形成条形孔道(即所述复合气孔30)，再将多个条形孔道间隔一定距离均匀分布至所述烟支100的整周，不仅高效的利用烟支的圆周，防止烟支折断，同时大面积条形孔道的出现更有利于提升烟支打孔的稳定性。通过打孔参数的组合，在完成烟支条形孔道打孔的同时，可有效的调整烟支的通风率，从而进一步调控加热卷烟的烟气温度和浓度。The heated cigarette 100 provided in this embodiment partially overlaps a plurality of the pore units 20 to form a strip-shaped channel (i.e., the composite pore 30), and then the plurality of strip-shaped channels are evenly distributed at a certain distance around the entire circumference of the cigarette 100, which not only efficiently utilizes the circumference of the cigarette to prevent the cigarette from breaking, but also the appearance of large-area strip-shaped channels is more conducive to improving the stability of cigarette punching. By combining punching parameters, the ventilation rate of the cigarette can be effectively adjusted while completing the punching of the cigarette strip-shaped channels, thereby further regulating the smoke temperature and concentration of the heated cigarette.

同时，本实施例还提供了一种加热卷烟的烟支100打孔方法，其包括如下步骤：At the same time, this embodiment also provides a method for punching holes in a heated cigarette 100, which comprises the following steps:

S2、确定所述烟支上所需开设的气孔参数； S2, determining the air hole parameters required to be opened on the cigarette;

S3、根据步骤S2中确定的气孔参数，沿所述烟支的径向，对所述烟支进行所述气孔开设，其中，所述气孔由气孔单元构成，且至少一个所述气孔为复合气孔，所述复合气孔至少由两所述气孔单元部分重合构成。S3. According to the pore parameters determined in step S2, the pores are opened in the cigarette along the radial direction of the cigarette, wherein the pores are composed of pore units, and at least one of the pores is a composite pore, and the composite pore is composed of at least two pore units partially overlapping.

通过所述气孔的数量、所述复合气孔中包含的所述气孔单元数量协同长度系数、脉冲时间可以更好的确保所述烟支的通风率，并且尽可能的降低对所述烟支结构强度的影响。The number of the pores, the number of pore units contained in the composite pores, the coordinated length coefficient, and the pulse time can better ensure the ventilation rate of the cigarette and reduce the impact on the structural strength of the cigarette as much as possible.

通过调节所述气孔的数量，用以设定构成每个所述复合气孔中条形孔叠加的所述气孔单元的个数，每个叠加的所述气孔单元圆心确保位于烟支的同一轴向位置，且单一所述复合气孔中叠加的所述气孔单元个数不超过16个；通过调节长度系数，用以设定每个所述复合气孔的长度。叠加的所述气孔单元重合面积越大，所述复合气孔越接近长方形，打孔质量越稳定，每相邻两个所述气孔单元，后一个所述气孔单元的外圆周与水平直径的单侧交点(重合部分)应位于前一个所述气孔单元外圆周与水平直径两个交点之间，实际打孔过程中，通过调节单一所述复合气孔中叠加的所述气孔单元个数和长度系数来控制相连所述气孔单元的叠加程度程度，当长度系数较高时，应增加叠加个数，当长度系数较低时，可适当减少叠加个数。也就是说，长度系数是反应所述复合气孔长度的一个参数。当其他参数确定时，所述长度系数越大则代表所述复合气孔越长，而当所述长度系数越小则代表所述复合气孔越短。脉冲时间为打单个所述气孔单元所需要的时间，通过调节该值，用以确保激光完全打穿所述烟支单侧表面的同时剩余能量不会使对侧所述烟支内表面形貌发生改变，在此基础上进一步用以调整每个所述复合气孔上单个叠加的所述气孔单元的直径。By adjusting the number of pores, the number of pore units constituting the superimposed strip holes in each composite pore is set. The center of each superimposed pore unit is ensured to be located at the same axial position of the cigarette, and the number of superimposed pore units in a single composite pore does not exceed 16; by adjusting the length coefficient, the length of each composite pore is set. The larger the overlapping area of the superimposed pore units, the closer the composite pore is to a rectangle, and the more stable the punching quality. For each adjacent two pore units, the single-sided intersection point (overlapping part) of the outer circumference of the latter pore unit and the horizontal diameter should be located between the two intersection points of the outer circumference of the former pore unit and the horizontal diameter. In the actual punching process, the degree of superposition of the connected pore units is controlled by adjusting the number of superimposed pore units and the length coefficient in a single composite pore. When the length coefficient is high, the number of superimposed units should be increased, and when the length coefficient is low, the number of superimposed units can be appropriately reduced. In other words, the length coefficient is a parameter that reflects the length of the composite pore. When other parameters are determined, the larger the length coefficient is, the longer the composite pore is, and the smaller the length coefficient is, the shorter the composite pore is. The pulse time is the time required to punch a single pore unit. By adjusting this value, it is ensured that the laser completely punches through the surface of one side of the cigarette and the remaining energy does not change the morphology of the inner surface of the opposite side of the cigarette. On this basis, it is further used to adjust the diameter of the single superimposed pore unit on each composite pore.

S22、确定所述复合气孔中包含的所述气孔单元数量n和长度*** α％，且气孔单元数量n和所述长度***α％的数值比值在以下范围内：3.5＜α/n＜7.5；S22, determining the number n and length system of the pore units contained in the composite pore α%, and the numerical ratio of the number of pore units n and the length system α% is within the following range: 3.5＜α/n＜7.5;

也就是说，本实施例中，在确定打孔参数时，是以开设的气孔的数量、复合气孔中包含的气孔单元数量协同长度系数、脉冲时间为优先级确定参数，按照上述参数权重采取先粗调后微调的方式逐步进行，可以更好的实现对所述烟支的打孔。在所述烟支被打穿的前提下，各打孔参数对打孔影响的大小依次为打孔的数量、复合气孔中包含的气孔单元协同长度系数、脉冲时间。That is to say, in this embodiment, when determining the punching parameters, the number of opened pores, the number of pore units in the composite pores, the coordinated length coefficient, and the pulse time are used as the priority to determine the parameters. According to the weight of the above parameters, the method of first coarse adjustment and then fine adjustment is gradually carried out, so as to better achieve the punching of the cigarette. On the premise that the cigarette is punched, the influence of each punching parameter on the punching is the number of punched holes, the coordinated length coefficient of the pore units in the composite pores, and the pulse time.

其中，开设的气孔的数量主要实现通风率数值的粗调，长度系数协同所述复合气孔中包含的所述气孔单元数量进一步调整通风率同时，根据二者比值优化烟支通风稳定性，通过脉冲时间确保所述烟支被打穿、并通过调整该参数实现烟支叠加圆孔径的调整，最终精准微调烟支通风率。Among them, the number of opened pores mainly realizes the coarse adjustment of the ventilation rate value, and the length coefficient cooperates with the number of pore units contained in the composite pore to further adjust the ventilation rate. At the same time, the ventilation stability of the cigarette is optimized according to the ratio of the two, and the pulse time is used to ensure that the cigarette is pierced, and the adjustment of the superimposed circular aperture of the cigarette is achieved by adjusting this parameter, and finally the ventilation rate of the cigarette is accurately fine-tuned.

首先应确定所需开设的气孔的数量，烟支通风与所述气孔的数量呈正相关关系，应基于此关系对固定要求的通风度进行对应的所述气孔的开设数调整，进一步的，当通风率要求在50％以上时，对于条形打孔，所述气孔不应低于4。First, the number of air holes required should be determined. The ventilation of cigarettes is positively correlated with the number of air holes. Based on this relationship, the number of air holes should be adjusted accordingly to meet the fixed ventilation requirements. Furthermore, when the ventilation rate is required to be above 50%, for strip perforations, the number of air holes should not be less than 4.

其次应确定单个所述复合气孔中包含的气孔单元数和长度系数，长度系数α％与单段打孔数n的数值比值范围为：3.5＜α/n＜7.5，在此范围内方可在所述烟支上打出孔道。脉冲时间一定时，单个所述复合气孔中包含的气孔单元数及长度系数与烟支通风呈正相关关系，α/n越小，叠加圆重合部分越大，通风率稳定性越高，应基于上述关系对固定要求的通风度进行对应的参数调整。进一步的，不宜设置过长的长度系数，以四指握住打孔烟支，拇指竖直，烟支中轴线与拇指平行时，按压打孔滤棒外侧，所述烟支无法折断为基准。Secondly, the number of pore units and the length coefficient contained in a single composite pore should be determined. The numerical ratio range of the length coefficient α% and the number of single-stage holes n is: 3.5＜α/n＜7.5. Only within this range can holes be punched on the cigarette. When the pulse time is constant, the number of pore units and the length coefficient contained in a single composite pore are positively correlated with the ventilation of the cigarette. The smaller α/n is, the larger the overlap of the superimposed circles is, and the higher the stability of the ventilation rate is. The corresponding parameter adjustment should be made for the fixed required ventilation degree based on the above relationship. Furthermore, it is not advisable to set an excessively long length coefficient. The benchmark is to hold the punched cigarette with four fingers, with the thumb vertical and the central axis of the cigarette parallel to the thumb, and press the outside of the punched filter rod, so that the cigarette cannot be broken.

最终应确定脉冲时间，脉冲时间与打孔直径在一定范围内呈正相关关系，基于最小打孔脉冲时间阈值，若需提高叠加圆直径，则应在确保脉冲时间不过载(可有效打出打孔卷烟)的情况下，适当提高脉冲时间。Ultimately, the pulse time should be determined. The pulse time is positively correlated with the perforation diameter within a certain range. Based on the minimum perforation pulse time threshold, if the superimposed circle diameter needs to be increased, the pulse time should be appropriately increased while ensuring that the pulse time is not overloaded (perforated cigarettes can be effectively punched out).

可以理解的是，为了确保打孔时，能有效打穿所述烟支。优选的，所述步骤S1与所述步骤S2之间还包括步骤S11、确定脉冲时间的最低阈值。It is understandable that in order to ensure that the cigarette can be effectively pierced during punching. The step S11 is further included between the step S1 and the step S2, determining the lowest threshold of the pulse time.

所述步骤S11包括如下步骤：The step S11 comprises the following steps:

S111、通过激光打孔设备先对所述烟支进行打孔；S111, punching holes in the cigarette by using a laser punching device;

S112、剪开打孔后的所述烟支；S112, cutting the punched cigarette;

S113、测量孔型长度与宽度。S113. Measure the length and width of the hole.

具体的，将剪开后的所述烟支平铺置于具有测量功能的显微镜下，正反测量复合气孔的长度与宽度(单个叠加圆的直径)，内外侧复合气孔长度比值应不低于80％；内外侧复合气孔宽度比值应不低于90％。Specifically, lay the cut cigarette flat under a microscope with a measuring function, and measure the length and width of the composite pores (the diameter of a single superimposed circle) from the front and back. The ratio of the length of the inner and outer composite pores should be no less than 80%; the ratio of the width of the inner and outer composite pores should be no less than 90%.

通过所述步骤S11可以更准确的选择后续参数，确保打孔过程中，所述烟支的单侧表面能够被激光有效打穿。Through the step S11, subsequent parameters can be selected more accurately to ensure that the single-side surface of the cigarette can be effectively punched through by the laser during the punching process.

本实施例提供的所述加热卷烟的烟支打孔方法多个所述气孔单元部分重合形成条形孔道(即所述复合气孔)，再将多个条形孔道间隔一定距离均匀分布至所述烟支的整周，可以确保圆周内打出较大进气面积的孔道，在有效的提升烟支通风率的同时，烟支不易被折断，不仅高效的利用烟支的圆周，防止烟支折断。同时大面积条形孔道的出现更有利于提升烟支打孔的稳定性，具体的，采用的小圆叠加形成条形孔的方法，减弱了单圆打孔时孔型尺寸变化带来的通风率波动，从而可有效的提升打孔后烟支通风的稳定性。通过对打孔数量、单个复合气孔中包含的气孔单元数量、长度系数以及脉冲时间进行组合，在完成烟支条形孔道打孔的同时，可改变烟支上开设的气孔的孔型，有效的调整烟支的通风率，从而进一步调控加热卷烟的烟气温度和浓度。采用的小圆叠加形成条形孔的方法，在人眼识别下即为长方形孔道，也增加了烟支打孔的新颖性和美观度。In the method for punching holes in heated cigarettes provided in this embodiment, a plurality of the pore units partially overlap to form a strip channel (i.e., the composite pore), and then the plurality of strip channels are evenly distributed at a certain distance around the entire circumference of the cigarette, so that a channel with a larger air intake area can be punched within the circumference, and the cigarette is not easily broken while effectively improving the ventilation rate of the cigarette. The circumference of the cigarette is not only efficiently utilized to prevent the cigarette from breaking. At the same time, the appearance of large-area strip channels is more conducive to improving the stability of cigarette punching. Specifically, the method of forming strip holes by superimposing small circles weakens the ventilation rate fluctuation caused by the change in hole size when punching a single circle, thereby effectively improving the ventilation stability of the cigarette after punching. By combining the number of holes, the number of pore units contained in a single composite pore, the length coefficient, and the pulse time, the hole type of the pores opened on the cigarette can be changed while completing the punching of the cigarette strip channel, and the ventilation rate of the cigarette can be effectively adjusted, thereby further regulating the smoke temperature and concentration of the heated cigarette. The method of forming strip holes by overlapping small circles appears as rectangular holes to the human eye, which increases the novelty and aesthetics of the cigarette holes.
