Description

吸烟系统及其吸烟装置
【技术领域】
本发明涉及烟具的技术领域，特别是涉及一种吸烟系统及其吸烟装置。
【背景技术】
传统卷烟作为烟草消费的主流产品形式，已有100多年的历史。随着人们生活方式和消费观念的转变、科学技术的快速进步和商品升级换代速度的不断加快，烟草消费者的需求和关注点不断变化，同时受到烟草控制、社会舆论等因素的影响，传统卷烟的发展受到制约，新型卷烟的出现已经成为必然。
电加热低温卷烟是一种以电力为热源，加热烟草物质，产生尼古丁烟雾的低温卷烟。传统的电加热低温卷烟在抽吸时，总粒相物在最初抽吸期间较低，但其趋于逐步提高直至最终，给消费者带来烟气强度逐渐增加的感觉。加热腔采取一体式加热方式抽吸常规卷烟时，烟气起始极弱，而后迅速上升，然后随着抽吸口数的增加，烟气量显著降低。这主要是因为其利用前几口抽吸达到最佳温度，使烟草制品产生高浓度气溶胶，然而随着抽吸进程，气溶胶产生殆尽。与常规卷烟相比，烟气释放量不可控，不同抽吸口数之间感官差异较大，吸食后期，感官特性趋于减弱。
【发明内容】
基于此，有必要提供一种抽吸过程中烟气释放量较为一致的吸烟系统及其吸烟装置。
一种吸烟装置，用于加热烟制品，所述吸烟装置包括:壳体，所述壳体上开设有容纳腔和连通所述容纳腔的进气口；以及加热锅，设置在所述容纳腔内；所述加热锅包括多个依次连接的加热元件，每一加热元件开设有加热腔，多个所述加热元件的所述加热腔形成用于容纳所述烟制品的容置腔；所述容置腔的两端分别设有用于插入所述烟制品的插入口和连通所述进气口的进气孔；多个所述加热元件独立控制温度，且从所述插入口往所述进气孔的方向顺序加热所述烟制品。
一种吸烟系统，包括烟制品和所述的吸烟装置；所述烟制品包括烟杆和烟嘴，所述烟杆的一端与所述烟嘴连接；所述烟杆插入所述容置腔内，所述烟杆包括多个依次连接的烟草段，多个所述烟草段与多个所述加热元件一一对应。
本发明的一个或多个实施例的细节在下面的附图和描述中提出。本发明的其它特征、目的和优点将从说明书、附图以及权利要求书变得明显。
【附图说明】
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他实施例的附图。

图2为图1所示吸烟系统中的吸烟装置的示意图；
图3为另一实施例中吸烟系统的示意图；
图4为图3所示吸烟系统中的烟制品的示意图；
图5为图3所示吸烟系统中的另一实施例的烟制品的示意图；
图6为图3所示吸烟系统中的容纳器和相变材料的示意图。
【具体实施方式】
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的首选实施例。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及／或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1所示，一实施方式的吸烟系统10包括吸烟装置100和烟制品200，吸烟装置100用于加热烟制品200，吸烟装置100在一定温度范围内加热烟制品200，控制烟制品200不燃烧，尼古丁和部分烟草香味成分就可改转移到烟气中供吸食，可以大幅度降低焦油和有害成分的释放量。
同时参见图2，吸烟装置100包括壳体120和加热锅140，壳体120上开设有容纳腔和连通容纳腔的进气口122。加热锅140设置在容纳腔内。加热锅140包括多个依次连接的加热元件142，在一实施例中，加热元件142可以为布设有加热电路的陶瓷结构，加热元件142的数量可以为2-15个。每一加热元件142开设有加热腔142a，多个加热元件142的加热腔142a形成用于容纳烟制品200的容置腔144。容置腔144的两端分别设有用于插入烟制品200的插入口146和连通进气口122的进气孔148。多个加热元件142独立控制温度，且从插入口146往进气孔148的方向顺序加热烟制品200。
由于加热锅140的多个加热元件142独立控制温度，且从插入口146往进气孔148顺序加热，因此烟制品200可以由烟嘴240一端向远离烟嘴240的方向顺序被加热。避免了整体加热时产生的高浓度气溶胶，抽吸过程中烟气释放量较为一致，从而平衡了不同抽吸口数之间的感官差异，提高烟气口感的一致性。
另外，如果加热锅140对烟制品200的加热顺序是与本实施例相反的，即从烟制品200的一端向烟嘴240的方向顺序加热，由于流过被加热烟草段242的气流具有较高温度，其会对后面流过的烟草段242进行加热，从而导致尚未加热的烟草段242中的部分烟气成分升华或分解温度较低的烟气成分被释放，从而提前带走了后加热烟草段242中的该部分烟气成分，导致最终不同烟草段242被加热时的烟气口感不一致。与此同时，过早加热卷烟未加热部位会导致产生部分烟雾或使卷烟该部位由于受热引起热致降解，改变自身品质。重新加热先前受热过的部位会导致产生不愉快的气味或有害成分。而本实施例中，采用从由烟嘴240一端向远离烟嘴240的方向顺序的方式，可以使得被加热气流不会流过未被加热的烟草段242，从而避免上述烟气口感不一致和产生不愉快的气味或有害成分问题。
在其中一个实施例中，吸烟装置100一般还包括为加热锅140供电的电源组件160，电源组件160可以在壳体120外部与壳体120连接，在其他实施例中，电源组件160也可以位于壳体120内部。或者吸烟装置100本身不具备电源组件160，吸烟装置100与外部的电源组件160可拆卸连接，实现为加热锅140供电。
为了更精准的控制和监测加热锅140的温度，在其中一个实施例中，加热锅140还包括多个温度感测器152，每个加热元件142上至少设置一个温度感测器152。在一实施例中，加热锅140还包括隔热垫圈154，隔热垫圈154位于相邻的加热元件142之间，以避免加热元件142之间导热而相互影响。
在一实施例中，吸烟装置100还可以包括控制器，控制器设置在容纳腔内，控制器用于控制对多个加热元件142独立供电。温度感测器152可以与控制器通信连接，控制器可以根据温度感测器152测试到的温度控制对加热元件142供电，以更准确的调整加热元件142的温度。
加热元件142的加热温度一般为200℃至500℃，尼古丁和多数烟草致香成分在200-500℃就可以转移到烟气中，温度过高容易产生有害气体或引燃烟制品200。进一步的，在一实施例中，加热元件142的加热温度为200℃至350℃。将温度控制的较低，一方面利于安全控制，避免烫伤，另一方面尼古丁和烟草致香成分可以较为平稳的速度释放出，吸食的口感更佳。
在其中一个实施例中，壳体120的内壁和加热锅140的外壁之间形成有预热通道156，预热通道156的一端连通进气口122，另一端连通进气孔148。参见图1中的箭头，当吸食烟制品200时，外部的空气由进气口122进入预热通道156，被加热锅140的外壁预热之后，经进气孔148进入容置腔144，而进入烟制品200。设计预热通道156，一方面可以降低加热锅140的外壁的温度，进而降低壳体120的温度，防止烫手，另一方面可以高效利用加热锅140的热量，避免能量浪费。
在一实施例中，壳体120呈圆管状，加热元件142也可以呈圆管状，烟制品200可以受热更均匀，进气口122和插入口146均位于壳体120的一端开口处。进一步的，在吸烟装置100具备电源组件160的实施例中，电源组件160可以位于壳体120的另一端，整体结构安排更合理，方便握持使用。
在图1所示的实施例中，烟制品200可以是普通市售的卷烟，同时参见图3、图4，在另一实施例中，烟制品200包括烟杆220和烟嘴240，烟杆220的一端与烟嘴240连接。烟杆220插入容置腔144内，烟杆220包括多个依次连接的烟草段242，多个烟草段242与多个加热元件142一一对应。烟草段242与加热元件142对应，多个烟草段242配合多个独立控制温度加热元件142，利于控制不同烟草段242的温度，还可以根据需要调整各个烟草段242的成分，使口感更好。
在其中一个实施例中，烟草段242包括烟料244和相变材料246，相变材料246设置在烟料244中。由于相变材料246在发生相变过程中会吸收大量热量或放出大量热量，所以能起到延缓升温降温的作用，可以避免温度升高或降低过快，从而能够更好的控制烟制品200的温度。
在其中一个实施例中，烟制品200还包括隔热层260，隔热层260位于相邻的两个烟草段242之间，每两个相邻的烟草段242之间均可以设置一个隔热层260，以避免烟草段242之间导热而相互影响。进一步的，在一实施例中，隔热层260还可以位于烟嘴240和与烟嘴240连接的烟草段242之间，避免热量传导至烟嘴240。同时参见图4，在另一实施例中，相邻的烟草段242可以直接连接，不设置隔热层260，亦可实现提高烟气口感的一致性和避免温度升高或降低过快的作用。
为了避免相变材料246熔化后被吸入口腔，同时参见图5，在一实施例中，烟制品200还可以包括用于容纳相变材料246的容纳器280，相变材料246位于容纳器280内，进一步的，容纳器280为熔点一般高于或等于500℃的导热材质。容纳器280的熔点需要高于加热元件142的加热温度。在一实施例中，容纳器280的材质为铝箔。容纳器280有很好的导热性，从而利于烟草段242内热量均匀化。容纳器280的形状可以类似胶囊，相变材料246包裹在容纳器280内。在一实施例中，容纳器280的数量为多个，多个容纳器280均匀分布于每个烟草段242的烟料244中，更利于烟草段242内热量均匀化。
相变材料246可以为颗粒状或丝状等。在一实施例中，相变材料246的固液相变温度为200℃至500℃，当加热元件142将相变材料246加热到固液相变温度时，相变材料246融化，相变材料246在发生相变过程中会吸收大量热量，从而避免温度升高过快。当相变材料246的温度低于固液相变温度时，相变材料246凝固，相变材料246在发生相变过程中会放出大量热量，从而避免温度降低过快。在一实施例中，相变材料246的相变温度也可以选择在240℃到350℃之间。例如，相变材料246例如可以为硝酸钠NaNO3。
在其中一个实施例中，多个烟草段242中的烟料244的成分不同。可以根据需要调整各个烟草段242的成分，使口感更好。例如，不同烟草段242采用不同品种的烟料244，使吸食过程中口味香型变化，丰富吸食体验。在一实施例中，多个烟草段242中的烟料244中含有的能够产生分解温度较低的烟气成分的烟草成分的比例，由靠近烟嘴240的一端向远离烟嘴240的方向逐渐减小。由于远离烟嘴240处的烟草段242产生的烟气会流经靠近烟嘴240的烟草段242，靠近烟嘴240的烟草段242虽然已经释放过烟气，但是在后续带有一定热量的烟气进入时，仍然会有少量的低温分解烟气释放出来，因此，将其成分的比例由靠近烟嘴240的一端向远离烟嘴240的方向逐渐减小，更利于提高烟气口感的一致性。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
