Abstract
An aerosol generation core strip (21), an aerosol generation substrate (20), and an aerosol generation device (100). The aerosol generation core strip (21) comprises an electromagnetic induction layer (211) and an aerosol generation layer (212), wherein the aerosol generation layer (212) coats the electromagnetic induction layer (211). By means of the electromagnetic induction layer (211), the aerosol generation core strip (21) generates a current on the basis of the induction of an electromagnetic field, and thus generates heat, thereby simplifying a heating device and improving the heating efficiency of the aerosol generation layer (212). In addition, since the aerosol generation layer (212) directly coats the electromagnetic induction layer (211), a production substrate is not required, and there is also no need to additionally insert an individual induction heating sheet into a bundle of the aerosol generation core strips (21), thereby simplifying the assembly production process.
Description
本发明涉及加热不燃烧发烟物品领域，具体地涉及一种加热不燃烧发烟物品的气溶胶发生芯条、气溶胶发生基材及气溶胶发生装置。The invention relates to the field of heat-not-burn smoking articles, in particular to an aerosol generating core strip, an aerosol generating substrate and an aerosol generating device for heat-not-burn smoking articles.
在控烟环境日趋严峻的背景下，加快新型烟草制品的研究显得迫在眉睫。加热不燃烧发烟物品作为新型烟草制品的重要组成部分，其通过加热而非点燃的方式进行抽吸，加热温度远低于燃烧温度，极大减少了因燃烧产生的焦油和有害成分，侧流烟气也大幅降低。In the context of increasingly severe tobacco control environment, it is imminent to accelerate the research of new tobacco products. As an important part of new tobacco products, heat-not-burn smoking articles are smoked by heating instead of igniting. The heating temperature is much lower than the combustion temperature, which greatly reduces the tar and harmful components caused by combustion. Side stream Smoke is also significantly reduced.
目前，加热不燃烧发烟物品的气溶胶发生基材主要由稠浆法、造纸法等工艺改良制得。稠浆法即将配方烟粉与一定量纤维混合，添加发烟剂、胶粘剂等助剂混合后调配成烟芯基材涂布液，将烟芯基材涂布液涂布于生产基片上，经过烘干后从生产基片上取下，分切后得到加热不燃烧发烟物品的气溶胶发生基材。At present, the aerosol-generating substrates of heat-not-burn smoking articles are mainly produced by improved processes such as thick slurry method and paper-making method. The thick slurry method is to mix the formula tobacco powder with a certain amount of fiber, add smoke-generating agents, adhesives and other additives, mix and prepare the coating liquid for the base material of the cigarette core, and coat the coating liquid of the core base material on the production substrate. After being dried, it is removed from the production substrate, and the aerosol generating substrate of the heat-not-burn smoking article is obtained after cutting.
其中，现有气溶胶发生基材中的气溶胶发生层的加热是靠不燃烧加热器具中的插入气溶胶发生基材内的单独的感应发热片，由于气溶胶发生基材是由多根气溶胶发生芯条并排布置构成，故不与感应发热片接触的气溶胶发生芯条的加热只能靠其它已被加热的气溶胶发生芯条来传递加热能量，因而使得气溶胶发生芯条的加热效率低；另，由于现有的烟芯基材涂布液涂布于生产基片上，故需要生产基片；此外，现有的气溶胶发生芯条为均质的，仅仅包含一层气溶胶发生层。Among them, the heating of the aerosol generating layer in the existing aerosol generating base material is to rely on the independent induction heating sheet inserted in the aerosol generating base material in the non-combustible heating device, because the aerosol generating base material is composed of multiple gas The aerosol generating core strips are arranged side by side, so the heating of the aerosol generating core strips that are not in contact with the induction heating sheet can only rely on other heated aerosol generating core strips to transfer heating energy, thus making the aerosol generating core strips heated The efficiency is low; in addition, because the existing coating solution of the base material of the cigarette core is coated on the production substrate, the substrate needs to be produced; in addition, the existing aerosol generating core strip is homogeneous and only contains one layer of aerosol occurrence layer.
因此，急需要一种气溶胶发生芯条、气溶胶发生基材及气溶胶发生装置来克服上述的缺陷。Therefore, there is an urgent need for an aerosol generating core strip, an aerosol generating substrate and an aerosol generating device to overcome the above-mentioned defects.

本发明的另一目的在于提供一种提高气溶胶发生层加热效率的气溶胶发生基材。Another object of the present invention is to provide an aerosol generating substrate which improves the heating efficiency of the aerosol generating layer.
本发明的又一目的在于提供一种提高气溶胶发生层加热效率的气溶胶发生装置，避免在气溶胶发生基材中单独置入独立的电磁感应发生片。Another object of the present invention is to provide an aerosol generating device that improves the heating efficiency of the aerosol generating layer, avoiding the need to separately insert an independent electromagnetic induction generating sheet into the aerosol generating substrate.
为了实现上述目的，本发明的气溶胶发生芯条包含一电磁感应层及一气溶胶发生层，所述气溶胶发生层涂布于所述电磁感应层上。In order to achieve the above object, the aerosol generating core strip of the present invention comprises an electromagnetic induction layer and an aerosol generating layer, and the aerosol generating layer is coated on the electromagnetic induction layer.
较佳地，本发明的气溶胶发生芯条还包含设置于所述电磁感应层与所述气溶胶发生层之间的过渡层，所述过渡层黏附于所述电磁感应层上，所述气溶胶发生层涂布于所述过渡层。Preferably, the aerosol generating core strip of the present invention further includes a transition layer arranged between the electromagnetic induction layer and the aerosol generating layer, the transition layer is adhered to the electromagnetic induction layer, and the aerosol The sol generating layer is coated on the transition layer.

较佳地，所述电磁感应层至少为一层，所述电磁感应层呈片状或网状。Preferably, the electromagnetic induction layer is at least one layer, and the electromagnetic induction layer is in the shape of a sheet or a mesh.
较佳地，所述气溶胶发生芯条的厚度大于或等于0.07毫米；所述电磁感应层由金属和纤维组成，或者，所述电磁感应层由合金和纤维组成。Preferably, the thickness of the aerosol generating core strip is greater than or equal to 0.07 mm; the electromagnetic induction layer is composed of metal and fiber, or the electromagnetic induction layer is composed of alloy and fiber.
较佳地，所述纤维为烟草纤维、软木纤维或硬木纤维。Preferably, the fibers are tobacco fibers, softwood fibers or hardwood fibers.
较佳地，所述气溶胶发生层中的气溶胶发生物占所述气溶胶发生芯条总量的10%~30%，所述气溶胶发生层中的气味发生剂占所述气溶胶发生芯条总量的百分比为大于0且小于或等于10%。Preferably, the aerosol generating substance in the aerosol generating layer accounts for 10% to 30% of the total amount of the aerosol generating core strip, and the odor generating agent in the aerosol generating layer accounts for 10% to 30% of the total amount of the aerosol generating core strip. The percentage of the total core strip is greater than 0 and less than or equal to 10%.
为实现上述的目的，本发明的气溶胶发生基材包含多根前述的气溶胶发生芯条。In order to achieve the above purpose, the aerosol generating substrate of the present invention comprises a plurality of aerosol generating core strips mentioned above.

为实现上述的目的，本发明的气溶胶发生装置包括一加热源及前述的气溶胶发生基材。To achieve the above object, the aerosol generating device of the present invention includes a heating source and the aforesaid aerosol generating substrate.
与现有技术相比，由于本发明的气溶胶发生芯条包含气溶胶发生层和电磁感应层，使得本发明的气溶胶发生芯条为非均质的；同时，由于本发明的气溶胶发生芯条中的电磁感应层的设置能更高效率将电磁感应发热产生的热量直接地传递给该气溶胶发生芯条中的气溶胶发生层，从而提高了气溶胶发生层加热效率和发烟效果。再者，由于本发明的气溶胶发生芯条中的气溶胶发生层直接地涂布于该气溶胶发生芯条中的电磁感应层上，避免了现有的气溶胶发生装置需要在气溶胶发生芯条中单独置入电磁感应发热片，简化了现有的气溶胶发生装置的生产过程。Compared with the prior art, since the aerosol generating core strip of the present invention comprises an aerosol generating layer and an electromagnetic induction layer, the aerosol generating core strip of the present invention is heterogeneous; at the same time, due to the aerosol generating core strip of the present invention The setting of the electromagnetic induction layer in the core strip can directly transfer the heat generated by electromagnetic induction heating to the aerosol generation layer in the aerosol generation core strip, thereby improving the heating efficiency and smoke effect of the aerosol generation layer . Furthermore, since the aerosol generating layer in the aerosol generating core strip of the present invention is directly coated on the electromagnetic induction layer in the aerosol generating core strip, it avoids the need for the existing aerosol generating device The electromagnetic induction heating sheet is separately placed in the core strip, which simplifies the production process of the existing aerosol generating device.

如图4所示，为气溶胶发生芯条21`的另一变形结构，该气溶胶发生芯条21`与前面描述到的气溶胶发生芯条21的区别在于：气溶胶发生芯条21`还包含设置于电磁感应层211与气溶胶发生层212之间的过渡层213，过渡层213黏附于电磁感应层211上，气溶胶发生层212涂布于过渡层213；以借助过渡层213的设置，使得气溶胶发生层212更容易黏附于电磁感应层212上。具体地，过渡层为纤维层，例如为但不于限此的纸层。As shown in Figure 4, it is another deformed structure of the aerosol generating core strip 21`. The difference between the aerosol generating core strip 21' and the aerosol generating core strip 21 described above is: the aerosol generating core strip 21` It also includes a transition layer 213 arranged between the electromagnetic induction layer 211 and the aerosol generating layer 212, the transition layer 213 adheres to the electromagnetic induction layer 211, and the aerosol generating layer 212 is coated on the transition layer 213; set so that the aerosol generating layer 212 is more easily adhered to the electromagnetic induction layer 212 . Specifically, the transition layer is a fiber layer, such as but not limited to a paper layer.
与现有技术相比，由于本发明的气溶胶发生芯条21（21`）包含气溶胶发生层212和电磁感应层211，使得本发明的气溶胶发生芯条21（21`）为非均质的；同时，由于本发明的气溶胶发生芯条21（21`）中的电磁感应层211的设置能更高效率将电磁感应发热产生的热量直接地传递给该气溶胶发生芯条21（21`）中的气溶胶发生层212，从而提高了气溶胶发生层212加热效率和发烟效果。再者，由于本发明的气溶胶发生芯条21（21`）中的气溶胶发生层212直接地涂布于该气溶胶发生芯条212中的电磁感应层211上，避免了现有的气溶胶发生装置需要在气溶胶发生芯条中单独置入电磁感应发热片，简化了现有的气溶胶发生装置的生产过程。Compared with the prior art, since the aerosol generating core strip 21 ( 21 ′) of the present invention includes the aerosol generating layer 212 and the electromagnetic induction layer 211 , the aerosol generating core strip 21 ( 21 ′) of the present invention is non-uniform At the same time, due to the setting of the electromagnetic induction layer 211 in the aerosol generating core strip 21 (21`) of the present invention, the heat generated by electromagnetic induction heating can be directly transferred to the aerosol generating core strip 21 ( 21'), thereby improving the heating efficiency and smoke generation effect of the aerosol generating layer 212. Furthermore, since the aerosol generating layer 212 in the aerosol generating core strip 21 (21') of the present invention is directly coated on the electromagnetic induction layer 211 in the aerosol generating core strip 212, the existing aerosol generating layer 212 is avoided. The aerosol generating device needs to separately insert an electromagnetic induction heating sheet in the aerosol generating core strip, which simplifies the production process of the existing aerosol generating device.
需要说明的是，由于加热源10为气溶胶发生基材20提供交变磁场作用，再结合气溶胶发生基材20中的气溶胶发生芯条21（21`）之电磁感应层211，使得电磁感应层211在交变磁场的作用下产生电流进而发热，达到由电磁感应层211加热气溶胶发生层212的目的，原理就像电磁炉一样。It should be noted that since the heating source 10 provides the alternating magnetic field for the aerosol generating substrate 20, combined with the electromagnetic induction layer 211 of the aerosol generating core strip 21 (21`) in the aerosol generating substrate 20, the electric Under the action of the alternating magnetic field, the magnetic induction layer 211 generates current and then generates heat, so as to achieve the purpose of heating the aerosol generation layer 212 by the electromagnetic induction layer 211, and the principle is the same as that of an induction cooker.
