Description

一种低温烟具 技术领域
本发明属于烟具领域，具体涉及一种低温烟具。
背景技术
相关研究表明，传统卷烟燃烧温度在800℃以上，卷烟在燃烧的过程中会产生5000余种化学物质，其中致癌的化学物质就有80多种，其产生的烟雾对非吸烟人群的危害相当大。加热不燃烧技术是一种通过低温烟具直接加热气溶胶基体(也称烟弹)但不燃烧产生烟雾的技术，这种加热方式所产生的有害物质比通过燃烧传统卷烟所产生的有害物质大大减少，在满足消费者需求的同时又可以减少对身体的危害。
加热不燃烧技术的主要用具为低温烟具，低温烟具通过对气溶胶基体进行加热，从而发生热解反应，使气溶胶基体内的烟草物料刚好加热到足以散发出烟草味道及烟雾的程度，以供用户吸食。
现有低温烟具是通过设置加热体，使加热体直接插入气溶胶基体实现对气溶胶基体的加热。但是采用该加热结构的加热方式较单一，已不能适应不同用户不同的使用习惯；为满足低温烟具的加热效率，现有的加热体多使用陶瓷片结构，由陶瓷片制成的加热体成本较高，且容易在使用时由于操作不当而造成对加热体的损伤。由于陶瓷片为片状结构，插拔气溶胶基体时容易带出加热后的烟叶，使用后不易清理。
发明内容
本发明提供了一种低温烟具，通过本发明可以提高低温烟具与气溶胶基体的兼容性。
本发明提供了一种低温烟具，低温烟具包括一个烟具壳体、一个加热针和 一个导热罩，烟具壳体形成有一个能够定位气溶胶基体的夹烟孔，加热针能够位于夹烟孔内，导热罩能够罩设加热针，并能够插入定位于夹烟孔的气溶胶基体。加热针通过罩设于自身的导热罩对气溶胶基体进行加热，改变了加热针与气溶胶基体之间的传热方式，加热针与气溶胶基体之间不会产生相互影响，提高了加热针与气溶胶基体之间的兼容性。
在低温烟具的一种示意性实施方式中，烟具壳体包括主体段壳体和能够拆装于主体段壳体的夹烟段壳体，夹烟孔开设于夹烟段壳体。
在低温烟具的一种示意性实施方式中，加热针固设于主体段壳体，导热罩固设于夹烟段壳体，且夹烟孔开设于夹烟段壳体，夹烟段壳体组装于主体段壳体后，加热针能够伸入夹烟孔，且导热罩能够罩设加热针。
在低温烟具的一种示意性实施方式中，加热针和导热罩固设于夹烟段壳体。
在低温烟具的一种示意性实施方式中，加热针沿夹烟孔的轴向设置。保证罩设加热针的导热罩沿夹烟孔的轴向设置，便于气溶胶基体的插入。
在低温烟具的一种示意性实施方式中，导热罩为圆锥形罩。圆锥形罩可以改善加热角度、增大加热面积，且在气溶胶基体插拔的过程中，减少与气溶胶基体内烟叶间的摩擦力，防止烟叶残留在导热罩上。
在低温烟具的一种示意性实施方式中，导热罩外表面具有防粘连层。防粘连层在导热罩插拔于气溶胶基体时，防止气溶胶基体内烟叶粘连在导热罩上。
在低温烟具的一种示意性实施方式中，导热罩的内侧和/或外侧贴附有导热层。导热层能够提高加热针与气溶胶基体之间的传热效果，缩短气溶胶基体的加热时间。
在低温烟具的一种示意性实施方式中，导热罩的厚度为0.15-0.35毫米。
在低温烟具的一种示意性实施方式中，导热罩的厚度与加热针的直径的比例C需满足：1/10＜C＜3/10。

最后，需要说明的是，当组件被称为“位于”或“设置于”另一个组件，它可以在另一个组件上或可能同时存在居中组件。当一个组件被称为是“连接于”另一个组件，它可以是直接连接到另一个组件或者可能同时存在居中组件。
在本发明中，除非特别指出，气溶胶基体均为加热不燃烧烟支。
图1为低温烟具的一种示意性实施方式的结构示意图，及低温烟具的一种示意性实施方式的分解结构示意图。图2为图1中的低温烟具剖视结构示意图，及低温烟具的一种示意性实施方式的局部结构分解示意图。如图1所示，低温烟具10包括一个烟具壳体12。其中，如图中实线部分，烟具壳体12形成有一个能够定位气溶胶基体20的夹烟孔122。
结合图2，低温烟具还包括一个加热针14及一个导热罩16，加热针14能够位于夹烟孔122内，导热罩16能够罩设加热针14，并能够插入定位于夹烟孔122的气溶胶基体20，气溶胶基体20定位于夹烟孔122的方向可参见图中虚线箭头部分。
将传统类型的陶瓷片式的加热体结构，更换为搭配导热罩的加热结构后，会通过导热罩的尺寸来确定加热气溶胶基体的加热面积，通过导热罩的形状来影响加热效果及使用效果。可以看到，通过搭配导热罩的方式，改变了加热针与气溶胶基体之间的传热方式，加热针与气溶胶基体之间不会产生相互影响，提高了加热针与气溶胶基体之间的兼容性；还可对加热体的加热效果及使用效果进行扩展。
在图2所示的实施方式中，加热针14沿夹烟孔122的轴向设置，导热罩 由于罩设加热针，使得导热罩同时沿夹烟孔的轴向设置，气溶胶基体在通过夹烟孔定位时，便于导热罩插入气溶胶基体。
为使夹烟孔适配不同类型的气溶胶基体，导热罩的厚度为0.15-0.35毫米。在此范围内，可以根据气溶胶基体的类型选择合适的导热罩，使得导热罩能够插入气溶胶基体，其中，导热罩的厚度优选为0.25毫米，可以理解的，低温烟具的加热方式为加热针加热，夹烟孔是对气溶胶基体起到定位的作用，因此，气溶胶基体与夹烟孔之间的连接关系不在本发明的研究范围内，且由于导热罩能够插入气溶胶基体，使得导热罩可对气溶胶基体起到固定的作用。
为使气溶胶基体获得最佳的加热效果，导热罩的厚度与加热针的直径的比例C需满足：1/10＜C＜3/10，其中，导热罩的厚度与加热针的直径的比例C优选为2/10。
图3为低温烟具的另一种示意性实施方式的结构示意图，及低温烟具的另一种示意性实施方式的分解结构示意图。其中，如图中实线部分，烟具壳体12包括主体段壳体11和能够拆装于主体段壳体11的夹烟段壳体13，该夹烟段壳体13能够沿图中虚线连接线拆卸地组装于主体段壳体11，且夹烟段壳体13形成有一个能够定位气溶胶基体20的夹烟孔122，气溶胶基体20能够沿虚线部分插接于夹烟孔122中。
图4用以说明图3中低温烟具的夹烟段壳体的一种示意性实施方式的剖视结构示意图，及低温烟具的一种示意性实施方式的局部结构分解示意图。在图4所示的实施方式中，加热针14固设于主体段壳体11，导热罩16固设于夹烟段壳体13，且夹烟孔122开设于夹烟段壳体13，夹烟段壳体13组装于主体段壳体11后，加热针14能够伸入夹烟孔122，且导热罩16能够罩设加热针14。
不同的夹烟段壳体可具有不同深度及孔径尺寸，以使不同的夹烟段壳体适配不同类型的气溶胶基体。同时为适配不同深度及孔径尺寸，即为适应不同类型的气溶胶基体，夹烟段壳体会相应装有不同尺寸或型号的导热罩，使得导热罩在固定气溶胶基体的同时，夹烟孔也可同时对气溶胶基体进行固定，提高使 用时的稳定性。使用者可配备多个上述夹烟段壳体，并根据实际使用需要选用，提高低温烟具的使用兼容性。
如上文所述，采用搭配导热罩的加热结构后，是通过改变导热罩的型号或尺寸使加热结构适配不同类型的气溶胶基体的，故夹烟段壳体可不带有加热针，使加热针位于主体段壳体。这样的方式使夹烟段壳体的结构可以更加简化，大大减小夹烟段壳体的制作成本，只需通过匹配不同的导热罩就可以使夹烟段壳体满足兼容性的问题。这样，使用者拥有一个带有加热针的主体段壳体后，只要根据需要选择匹配有不同型号导热罩的夹烟段壳体即可，因上述结构的夹烟段壳体的成本较低，使用者也愿意拥有更多型号的上述夹烟段壳体。
另外，由于夹烟段壳体不具有加热针，故夹烟段壳体本身是可以作为提烟器使用的，提烟器即用来帮助取下气溶胶基体的装置，以防止气溶胶基体内的烟叶残留在加热针上，因加热体本身一般是通过导电实现加热的，故清理时不太方便，可借助提烟器将气溶胶基体整体取出。如图4所示，因导热罩罩设于加热针，使加热针不会与气溶胶基体的烟叶直接接触，直接取出夹烟段壳体就可以实现气溶胶基体和带有加热针的主体段壳体的分离，而仅具有导热罩的夹烟段壳体还是很容易清理的。
参见图4，导热罩16可采用锥形罩，锥形罩可以改善加热角度、增大加热面积，且在气溶胶基体插拔的过程中，减少与气溶胶基体内烟叶间的摩擦力，防止烟叶残留在导热罩上。
为了进一步防止烟叶残留在导热罩上，导热罩16外表面具有防粘连层。防粘连层的材质可选用为聚四氟乙烯。
导热罩16的内侧和/或外侧贴附有导热层。导热层能够提高加热针与气溶胶基体之间的传热效果，缩短气溶胶基体的加热时间。根据设计需要的不同，导热层可设置于导热罩内侧或导热罩外侧，或同时设置于导热罩的内侧及外侧。
可以理解的，当导热层设置在导热罩外侧时，防粘连层与导热层的位置关系为防粘连层设置于导热层的外侧，能够防止烟叶残留在导热层上，从而影响 导热效果。为了降低成本，当导热层设置在导热罩外侧时，可将导热层与防粘连层设置为一体结构，既可以完成导热功能，又能够防止烟叶残留。
当然根据设计需要的不同，夹烟段壳体13也可以包括加热针14，加热针14固设于夹烟段壳体13，请参见图5，图5用以说明低温烟具的夹烟段壳体的另一种示意性实施方式的剖视结构示意图，及低温烟具的另一种示意性实施方式的局部结构分解示意图。如图5所示，将加热针14固设于夹烟段壳体13，使加热针14和导热罩16构成一个整体结构，虽然该结构没有图4所示夹烟段壳体结构的成本优势，但是如上文所述，搭配导热罩的加热结构本身就可以简化对加热体本身的结构要求，如在图5所示的实施方式中，加热针14沿夹烟孔122的轴向设置，导热罩由于罩设加热针，使得导热罩同时沿夹烟孔的轴向设置，气溶胶基体在通过夹烟孔定位时，便于导热罩插入气溶胶基体。
结合图5，导热罩16也可选为只有端部为锥形的结构，锥形的端部便于气溶胶基体的插入，导热罩除锥形端部的部分也会在锥形端部的引导下插入气溶胶基体。
可以理解的，在图5所示的实施方式中，导热罩16外表面也可设置为具有防粘连层的结构，且导热罩16的内侧和/或外侧贴附有导热层，设置方式可参见上文相关描述，此处不再赘述。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
