Description

一种具有气凝胶隔热层的新型卷烟加热器 技术领域
本发明属于卷烟技术领域，具体涉及一种具有隔热层的新型卷烟加热器。
背景技术
随着公众对传统卷烟危害性认识的加强和政府对传统卷烟管制力度的加大，世界各国烟草企业均加强了对新型烟草制品的开发，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。其中，新型卷烟通过加热烟草而非燃烧烟草，以烘烤出烟草中的香味物质的方式向人体传送尼古丁和香味，在生理感受、心理感知、吸食方式等方面比较接近传统卷烟，容易被烟草消费者接受，是一类极具发展潜力的新型烟草制品。因此，发展新型卷烟、加快由传统卷烟向新型卷烟的延伸，是促进烟草行业未来发展的重要手段之一。
新型卷烟使用时的加热温度通常在500℃，为了保证消费者在使用时不被烫伤或灼伤，需要在新型卷烟壳体和加热腔之间设置一个隔热层。一方面，隔热层可以起隔热保护的作用；另一方面，隔热层还能够减少加热器的热量损失，从而提高热能利用率、降低成本。目前，新型卷烟仍处于研发中，市场上还未出现可售产品。其中，隔热层的设计是新型卷烟研发中的一大难题。因此，选取合适的隔热层材料、开发隔热效果优异的新型卷烟加热器具有重要的意义。
发明内容
为了解决以上问题，本发明提供了一种具有气凝胶隔热层的新型卷烟加热器，其具有隔热保护、降低热能损失的作用。
本发明涉及一种具有气凝胶隔热层的新型卷烟加热器，其包括壳体1、加热元件3、由所述加热元件3形成的加热腔4和位于所述加热元件3和所述壳体1之间的隔热层2，其特征在于：所述隔热层2的隔热材料为气凝胶且所述隔热层2分为内层2-1和外层2-2，内层2-1直接与加热元件3接触，外层2-2则位于内层2-1与壳体1之间；且在所述隔热层2的外层2-2的气凝胶多孔结构中填充和/或吸附有2％-20％体积分数的相变材料。
所述相变材料是指在一定的温度范围内，利用材料本身物理状态，例如相态(例如固态转化为液态等)或结构(例如聚合度、晶型等)的变化，向环境吸收或释放相变潜热，从而达到调控环境温度的一类物质。当环境温度高于相变温度时，材料吸收并储存热量，以降低环境温度；当环境温度低于相变温度时，材料释放储存的热量，以提高环境温度。如果相变材料相变前后相态分别为固体和液体，则其相变类型为固－液，将这样的相变材料称为固-液相变材料；如果相变材料相变前后相态均为固体，则其相变类型为固－固，将这样的相变材料称为固-固相变材料。以固－液相变为例，当相变材料被加热到熔化温度时，就产生从固态到液态的相变，熔化的过程中，相变材料吸收并储存大量的潜热；当相变材料冷却时，储存的热量在一定的温度范围内要散发到环境中去，进行从液态到固态的逆相变。在这两种相变过程中，所储存或释放的能量称为相变潜热。物理状态发生变化时，材料自身的温度在相变完成前几乎维持不变，形成一个宽的温度平台，虽然温度不变，但吸收或释放的潜热却相当大。
隔热层2的存在能隔绝加热器的热量，降低手感温度，起到保护使用者的作用；同时可以降低加热元件的热量散失，提高热能利用率，降低成本。本发明的所述隔热层起到隔热效果来自两 方面的作用：一方面为气凝胶材料的存在，气凝胶是一种由超微颗粒相互聚结构成的并以空气作为分散介质的高分散固态材料，具有高通透性的三维纳米网络结构，其最高能承受1400℃的高温且导热性低、绝缘能力好，本身就是优良的隔热材料；另一方面为在所述气凝胶材料内填充有相变材料，将相变温度为常温至90℃的常温相变材料用于新型卷烟的隔热层中可以显著增强隔热层的隔热效果，当使用者抽吸新型卷烟时，一旦加热腔的温度高于相变材料的相变温度，相变材料就会利用自己本身相态或结构的变化吸收并储存热量，使得隔热层外部的温度不致于升得太高；而当抽吸结束后，当温度降低到该相变材料的相变温度以下时，相变材料则会释放储存的热量，并恢复到吸热相变前的状态，如此循环使用，起到调节温度的作用。
在本发明优选的实施方案中，所述气凝胶为无机气凝胶、有机气凝胶或有机-无机杂化气凝胶。在进一步优选的实施方案中，其中所述无机气凝胶为二氧化硅气凝胶、二氧化钛气凝胶、氧化铝气凝胶、氧化锡气凝胶、氧化锆气凝胶、氧化钒气凝胶中的任一种或它们的组合；其中所述有机气凝胶为间苯二酚-甲醛气凝胶、三聚氰胺-甲醛气凝胶、石墨烯气凝胶、聚酰亚胺气凝胶、壳聚糖气凝胶、甲壳素气凝胶、纤维素气凝胶或由以上有机气凝胶制备的碳气凝胶中的任一种或它们的组合；其中所述有机-无机杂化气凝胶为倍半硅氧烷凝胶、桥联倍半硅氧烷凝胶和复合凝胶中的任一种或它们的组合，其中所述复合凝胶由所述无机凝胶、有机凝胶和倍半硅氧烷复合得到。
根据进一步的技术方案，将所述气凝胶与耐热纤维混合，制备纤维增强气凝胶复合材料，其中所述耐热纤维为石英纤维、玄武岩纤维、莫来石纤维、碳纤维、碳化硅纤维、氧化铝纤维或硼 硅碳氮纤维中的任一种或它们的组合。
根据进一步的技术方案，其中所述气凝胶的应用形式为柔性毡、复合柔性毡、颗粒或粉末。当所述气凝胶的应用形式为颗粒或粉末时，在所述气凝胶的外表面喷涂气凝胶涂层和/或包裹一层铝箔，防止气凝胶粉末或颗粒掉落。
在本发明优选的实施方案中，所述相变材料为有机类相变材料、无机-有机杂化类相变材料和/或复合相变材料。在进一步优选的实施方案中，其中所述有机类相变材料选自相变类型为固-液的脂肪烃(例如石蜡)、脂肪酸和脂肪酸酯和/或相变类型为固-固的新戊二醇、三羟甲基乙烷、聚乙二醇中的一种或多种。
其中所述无机-有机杂化类相变材料选自二氧化硅-脂肪酸复合物、蒙脱土-脂肪酸复合物、珍珠岩-脂肪酸复合物或超轻陶砂-脂肪酸复合物中的一种或多种；其中所述复合相变材料包括应用微胶囊技术在相变类型为固-液的有机类相变材料表面包覆一层性能稳定的膜(例如以三聚氰胺-甲醛作为膜材)而构成的具有核壳结构的相变微胶囊。或者可将固-液有机相变材料渗入从亚微米到数百微米的多孔介质孔径空间内，占据大部分的孔空间，从而形成复合相变材料。复合相变材料解决固-液相变材料使用不方便的缺点，其生产工艺简单，无腐蚀性，性能较稳定。应用到新型卷烟的隔热层时，可将相变材料填充或吸附到气凝胶孔隙中，占据大部分孔空间，形成的复合材料可具有显著的相变储热降温功能和优良的耐久性能。
在更进一步优选的实施方案中，所述相变材料为固-固相变材料，所述固-固相变材料利用自身聚合度或晶型等的变化来改变自身物理状态，从而使材料自身的温度在相变前后几乎维持不变。以通过晶型变化的固-固相变材料为例，当固-固相变材料吸 收热量时，原本有序的晶型结构变得杂乱无章，或者从一种晶型转化为另一种晶型，从而将能量储存在相变材料中，而当环境温度降低时，相变材料本身释放能量，重新回到原本有序的晶型结构中。上述晶型转变过程中，材料本身的温度基本维持不变或仅有很小变化。固-固相变材料具有以下优点：(1)无需容器盛装，可以直接加工成型；(2)固—固相变膨胀系数较小，体积变化小；(3)过冷程度轻，无相分离现象；(4)无毒、无腐蚀、无污染；(5)热效率高，性能稳定，使用寿命长；(6)使用方便，装置简单。
在本发明优选的实施方案中，所述隔热层2的厚度为1mm-10mm，优选为2mm-8mm。
在本发明优选的实施方案中，其中所述隔热层2完全覆盖加热元件3，其形状随加热元件3的形状变化而变化。
使用本发明的隔热层，其在室温下的导热系数低于0.03W/m·K，500℃时的导热系数低于0.05W/m·K，可将壳体的温度保持在室温到45℃之间，优选室温到40℃之间。与所述隔热层接触的加热元件的最高使用温度在600℃到1000℃之间。
本发明的有益效果为：
1、气凝胶隔热层能够很好地隔绝加热器的热量，降低手感温度，保证壳体的温度<45℃。
2、隔热层能够减缓热量散失，节约能源，提高利用率。
3、气凝胶孔隙中填充或吸附有相变吸热材料，可强化其隔热能力，使得同样隔热能力下气凝胶层可以更薄，这有利于在新型卷烟这种精密器件中使用。
4、本发明结构简单、制造方便、成本低廉、使用便捷。
