技术领域Technical field
本发明涉及烟草技术领域,特别涉及一种感应加热的发烟片及烟草制品。The present invention relates to the field of tobacco technology, and in particular to an induction-heated smoking piece and tobacco products.
背景技术Background technique
烟草在燃烧时产生的烟雾中存在多种致癌物质,对人体的健康会产生非常大的危害,电加热烟具应市而生。电加热烟具是通过电子设备加热烟草物质的抽吸方式。电加热烟具包括电阻加热和电磁加热两种烟具。电阻加热的电加热烟具通过电加热的管、针或板等形式的加热元件与烟支或烟丝直接接触,在低于烟支燃点的温度下通过对烟支或烟丝的直接接触烘烤,使烟草的致香成分挥发出来,满足吸烟者对烟草的吸食要求。但是电阻加热的加热方式加热效率低,目前,加热不燃烧卷烟的加热方式的研究方向主要是电磁感应加热。There are many carcinogens in the smoke produced when tobacco is burned, which will cause great harm to human health. Electric heating smoking devices have emerged in the market. Electrically heated smoking devices are a smoking method that uses electronic devices to heat tobacco substances. Electrically heated smoking sets include resistance heating and electromagnetic heating smoking sets. Electrically heated smoking articles with resistance heating are in direct contact with cigarettes or shredded tobacco through heating elements in the form of electrically heated tubes, needles or plates, and bake the cigarette or shredded tobacco through direct contact at a temperature lower than the ignition point of the cigarette. The aroma-causing components of tobacco are evaporated to meet the smoker's smoking requirements. However, resistance heating has low heating efficiency. At present, the research direction of heating methods for heat-not-burn cigarettes is mainly electromagnetic induction heating.
电磁感应加热是利用高频电流加热原理,将交流电转化为高频电流,进而产生高频磁场,当磁场内磁力线作用在加热元件时,磁力线被切割,产生大量小涡流,使得加热元件自身迅速发热,从而达到加热卷烟的目的。常见的感应加热烟支包括在发烟物质中内置感受体或在发烟物质中添加磁性颗粒。在发烟物质中内置感受体,通常是将感受体放置在发烟物质的中心,这样导致感受体只能与其邻近的发烟物质紧密接触,而对烟支外围的发烟物质的加热效果不佳,导致加热不均匀,不能有效利用全部发烟物质。在发烟物质中添加磁性颗粒,不能保证颗粒在发烟物质中均匀分布,并且颗粒的接触面积较小,为实现较好的加热效果则需要添加的颗粒数量较多,增加了工艺复杂性和加工成本。Electromagnetic induction heating uses the principle of high-frequency current heating to convert alternating current into high-frequency current, thereby generating a high-frequency magnetic field. When the magnetic field lines in the magnetic field act on the heating element, the magnetic field lines are cut, generating a large number of small eddy currents, causing the heating element itself to heat up rapidly , thereby achieving the purpose of heating cigarettes. Common induction heating cigarettes include built-in receptors in the smoking material or magnetic particles added to the smoking material. When the receptor is built into the smoking substance, the receptor is usually placed in the center of the smoking substance. This causes the receptor to only be in close contact with the adjacent smoking substance and has little heating effect on the smoking substance on the periphery of the cigarette. It is not good, resulting in uneven heating and inability to effectively utilize all the smoking substances. Adding magnetic particles to the smoking material cannot ensure that the particles are evenly distributed in the smoking material, and the contact area of the particles is small. In order to achieve a better heating effect, a larger number of particles needs to be added, which increases the complexity of the process and Processing costs.

在一实施例中,烟草段7包括若干片矩形的感应加热的发烟片,各个所述感应加热的发烟片平行设置,且所述感应加热的发烟片平行于烟草段7的轴线设置,如图6和图7所示。不同的所述感应加热的发烟片之间留设有第一间隙702,便于气流流通。具体的制作过程为:对复合好的上述感应加热的发烟片进行切片工艺,为确保切片后的发烟物质的结构稳定性, 通常情况下,切片后的发烟片尺寸比需要位置的发烟片尺寸要大,通常将发烟片切成稍大的块状矩形结构,确保复合好的发烟物质整体不会在运输和烟支卷接的过程中分散开。卷接烟支时,将多块发烟片平行于烟支的轴线进行排布,每块发烟片之间留有第一间隙702。In one embodiment, the tobacco section 7 includes several rectangular induction-heated smoking pieces, each of the induction-heated smoking pieces is arranged in parallel, and the induction-heated smoking pieces are arranged parallel to the axis of the tobacco section 7 , as shown in Figure 6 and Figure 7. A first gap 702 is left between different induction heated smoke generating pieces to facilitate air flow. The specific production process is: perform a slicing process on the composite above-mentioned induction-heated smoking pieces. In order to ensure the structural stability of the sliced smoking materials, usually, the size of the sliced smoking pieces is larger than the size of the smoke-generating pieces at the required position. The size of the cigarette pieces should be large, and the cigarette pieces are usually cut into slightly larger block-shaped rectangular structures to ensure that the composite smoking material as a whole will not be scattered during transportation and cigarette rolling. When rolling a cigarette, multiple smoking pieces are arranged parallel to the axis of the cigarette, leaving a first gap 702 between each smoking piece.
在另一实施例中,烟草段7包括若干片圆形的感应加热的发烟片,各个所述感应加热的发烟片平行设置,且所述感应加热的发烟片垂直于烟草段7的轴线(即烟支的轴线)设置,如图4和图5所示。不同的所述感应加热的发烟片之间留设有第二间隙701。具体的制作过程为:对复合好的所述感应加热的发烟片切成与烟支直径相当的圆形结构,再将多个切好的圆形发烟片进行堆叠排布,最后使用卷烟纸进行卷接。由于复合成型的上述发烟片的孔隙度较小,因此为了确保烟支抽吸时的气流通畅,先通过固定层5对堆叠排布的圆形发烟片卷接,再卷接卷烟纸包裹圆形发烟物质形成烟草段7,再通过卷烟纸将烟草制品的非烟草段与烟草7段卷接成一体。In another embodiment, the tobacco section 7 includes several circular induction-heated smoking pieces, each of the induction-heated smoking pieces is arranged in parallel, and the induction-heated smoking pieces are perpendicular to the edges of the tobacco section 7 The axis (that is, the axis of the cigarette) is set as shown in Figures 4 and 5. A second gap 701 is left between different induction heated smoke generating pieces. The specific production process is as follows: cut the composite induction-heated smoking pieces into a circular structure with a diameter equivalent to that of a cigarette, then stack and arrange multiple cut circular smoking pieces, and finally use cigarettes. The paper is rolled and spliced. Since the porosity of the composite molded smoking sheets is small, in order to ensure smooth airflow when smoking the cigarette, the stacked circular smoking sheets are first rolled through the fixing layer 5 and then wrapped in cigarette paper. The circular smoking material forms the tobacco section 7, and then the non-tobacco section of the tobacco product and the tobacco section 7 are rolled into one body through cigarette paper.
