实施方式一
本申请实施方式一所提供一种加热器，用于加热固体发烟物质，并挥发所述固体发烟物质中至少一种成分形成气溶胶供用户吸食；加热器包括基体和红外发热组件。
请参考图1所示，基体11内部形成有用于接收固体发烟物质的腔室、且具有相对的敞口端和封闭端；固体发烟物质可通过敞口端接收于腔室内或从腔室内移除。基体11可以为圆柱体状、棱柱体状或者其他柱体状。基体11优选为圆柱体状，腔室即为基体11中的圆柱体状孔，将固体发烟物质置于腔室内可对其进行加热。
基体11可以选用耐高温且具有较高的红外线透过率的材料制成，包括但不限于以下材料：石英玻璃、蓝宝石、碳化硅、氟化镁陶瓷、氧化钇陶瓷、镁铝尖晶石陶瓷、钇铝石榴石单晶或锗单晶等等。优选的，基体11由石英玻璃制成。
固体发烟物质可以是卷烟、烟丝、烟块、烟梗和/或烟膏等固体发烟物质，也可以是烟草类、中草药类、香料类等半成品或成品。以固态的气溶胶形成基质为例，气溶胶形成基质是一种能够释放可形成气溶胶的挥发性化合物的基质。这种挥发性化合物可通过加热该气溶胶形成基质而被释放出来。气溶胶形成基质可吸附、涂覆、浸渍或以其它方式装载到载体或支承件上。气溶胶形成基质可便利地是气溶胶生成制品或吸烟制品的一部分。
气溶胶形成基质可以包括尼古丁。气溶胶形成基质可以包括烟草，例如可以包括含有挥发性烟草香味化合物的含烟草材料，当加热时所述挥发性烟草香味化合物从气溶胶形成基质释放。优选的气溶胶形成基质可以包括均质烟草材料，例如落叶烟草。气溶胶形成基质可以包括至少一种气溶胶形成剂，气溶胶形成剂可为任何合适的已知化合物或化合物的混合物，在使用中，所述化合物或化合物的混合物有利于致密和稳定气溶胶的形成，并且对在气溶胶生成系统的操作温度下的热降解基本具有抗性。合适的气溶胶形成剂是本领域众所周知的，并且包括但不限于：多元醇，例如三甘醇，1,3-丁二醇和甘油；多元醇的酯，例如甘油单、二或三乙酸酯；和一元、二元或多元羧酸的脂肪酸酯，例如二甲基十二烷二酸酯和二甲基十四烷二酸酯。优选的气溶胶形成剂是多羟基醇或其混合物，例如三甘醇、1,3-丁二醇和最优选的丙三醇。
红外发热组件，用于接受电源的电功率产生热量，并将产生的热量至少以红外线辐射的方式从基体11的封闭端传递给接收于腔室内的固体发烟物质，以生成供吸食的气溶胶。生成的气溶胶被从敞口端流经过的气流带走。
在本示例中，并没有在基体11的侧面或者封闭端的端面上设置通气孔，这样，一方面避免了固体发烟物质及其残渣颗粒从透气孔掉落出去，导致固体发烟物质及其残渣颗粒被反复加热之后产生异味和有害气体的问题；另一方面，通过红外线辐射的方式从基体11的底部对固体发烟物质进行加热，固体发烟物质受热均匀、升温速度较快。
请参考图2所示，在一示例中，红外发热组件包括红外电热层12、导电模块(13、14)。
红外电热层12形成在封闭端的端面，可以是封闭端的内端面或者外端面，也可以是封闭端的部分端面或者整个端面，还可以部分形成在基体11的侧面。 优选的红外电热层12形成在封闭端的整个外端面。
在图2的示例中，红外电热层12优选的由远红外电热油墨、陶瓷粉末和无机粘合剂充分搅拌均匀后涂印在封闭端的外表面上，然后烘干固化一定的时间，红外电热层12的厚度为30μm-50μm；当然，红外电热层12还可以由四氯化锡、氧化锡、三氯化锑、四氯化钛以及无水硫酸铜按一定比例混合搅拌后涂覆到封闭端的外表面上；或者为碳化硅陶瓷层、碳纤维复合层、锆钛系氧化物陶瓷层、锆钛系氮化物陶瓷层、锆钛系硼化物陶瓷层、锆钛系碳化物陶瓷层、铁系氧化物陶瓷层、铁系氮化物陶瓷层、铁系硼化物陶瓷层、铁系碳化物陶瓷层、稀土系氧化物陶瓷层、稀土系氮化物陶瓷层、稀土系硼化物陶瓷层、稀土系碳化物陶瓷层、镍钴系氧化物陶瓷层、镍钴系氮化物陶瓷层、镍钴系硼化物陶瓷层、镍钴系碳化物陶瓷层或高硅分子筛陶瓷层中的一种；红外电热层12还可以是现有的其他材料涂层。
导电模块(13、14)包括间隔设置的电极13和电极14，电极13和电极14中的至少一个设置在封闭端的端面上。电极13和电极14均至少部分地与红外电热层12电性连接，以使得电流可以经由红外电热层12从其中一个电极流向另一个电极。红外电热层12通过电极13和电极14接受电源的电功率产生热量，并将产生的热量至少以红外线辐射的方式从封闭端传递给接收于腔室内的固体发烟物质。电极13和电极14的极性相反，例如：电极13为正极、电极14为负极；或者电极13为负极、电极14为正极。
在图2的示例中，电极13和电极14形成在封闭端的端面上，红外电热层12设置在电极13和电极14之间的封闭端的部分端面上。电极13紧邻封闭端周边设置，电极14覆盖封闭端中心位置设置。以圆柱体状的基体11为例，封闭端的端面为圆形，电极13可以为紧邻封闭端圆周设置的环形电极，电极14可以为覆盖封闭端圆心位置的圆形电极。
请参考图3所示，在另一示例中，电极13和电极14分别为以一个固定点向外旋绕而形成的平面螺旋线，其中固定点紧邻封闭端中心位置设置，具体地固定点以封闭端的端面的中心位置为对称中心设置。平面螺旋线的电极相对图2的示例，可以降低红外电热层12的等效电阻，提高红外电热层12的电热转换效率。
进一步地，形成的两条平面螺旋线的电极均可以延伸到基体11的侧面上以形成两个侧电极，以使得延伸到基体11侧面的平面螺旋线的部分与电源连接，例如：通过导线与电源的正负极连接。另外，形成的两个侧电极之间涂覆红外电热层12的话，可以通过红外线辐射的方式从基体11的底部和侧面同时对固体发烟物质进行加热。很容易想象的到，形成的两条平面螺旋线电极中一条平面螺旋线电极延伸到基体11的侧面上，也是可以的。
请参考图4所示，与图2的示例不同的是，电极13、红外电热层12以及电极14沿着基体11的纵向方向依次形成在封闭端的端面上。
在该示例中，电极13覆盖封闭端外端面的至少一部分；红外电热层12和电极14覆盖电极13的一部分，以使得未被红外电热层12和电极14覆盖的电极13的部分与电源的正极或负极连接。
在该示例中，电极13、红外电热层12以及电极14可以均是连续膜层，例如：电极13和电极14均是面电极，电极13覆盖封闭端外端面的至少一部分，红外电热层12和电极14覆盖电极13的一部分；或者，电极13是非连续膜层，例如：电极13是网状电极，网状电极的网孔形状为菱形、方形、圆形、三角形或不规则图形等等。
在该示例中，相对图2的示例来说，红外电热层12的导电截面积显著地增大了，红外电热层12可选用电阻率较高的材料，例如：
红外电热层12可以选用氧化物、碳材料、碳化物或氮化物等具有较高红外辐射率的材料制成。具体地如下所示：
金属氧化物及多组分合金氧化物，包括：三氧化二铁、三氧化二铝、三氧化二铬、三氧化二铟、三氧化二镧、三氧化二钴、三氧化二镍、三氧化二锑、五氧化二锑、二氧化钛、二氧化锆、二氧化锰、二氧化铈、氧化铜、氧化锌、氧化镁、氧化钙或三氧化钼等；也可以是以上两种或两种以上金属氧化物的组合；还可以是具有尖晶石、钙钛矿或橄榄石等晶胞结构的陶瓷材料。
碳材料的发射率接近于黑体特性，具有较高的红外辐射率。碳材料，包括：石墨、碳纤维、碳纳米管、石墨烯或类金刚石薄膜等。
碳化物，包括：碳化硅，碳化硅在较大的红外线波长范围内(2.3微米-25 微米)具有高发射率，是较好的近全波段红外辐射材料；此外，还有碳化钨、碳化铁、碳化钒、碳化钛、碳化锆、碳化锰、碳化铬或碳化铌等，都具有较高的红外发射率(MeC相不具备严格的化学计算成分和化学式)。
氮化物，包括：金属氮化物和非金属氮化物，其中金属氮化物包括：氮化钛、碳氮化钛、氮化铝、氮化镁、氮化钽或氮化钒等；非金属氮化物包括：氮化硼、五氮化三磷或氮化硅(Si 3N 4)等。
其他无机非金属材料，包括：二氧化硅、硅酸盐(包括磷硅酸盐、硼硅酸盐等)、钛酸盐、铝酸盐、磷酸盐、硼化物或硫系化合物等。
红外膜层12可采用物理气相沉积方法、化学气相沉积方法、喷涂方法形成在基体11的封闭端的外表面上。优选的采用物理气相沉积方法沉积在基体11的封闭端的外表面上。
请参考图5所示，与图5的示例不同的是，电极13覆盖封闭端外端面的至少一部分(图中的131所示)、且沿封闭端外端面延伸到基体侧面(图中的132所示)，以使得延伸到基体11侧面的第一电极的部分132与电源的正极或负极连接。
在一示例中，加热器还包括形成在基体11侧面上的红外线反射涂层，用于反射从基体侧面11透射的红外线。
在该示例中，红外电热层12生成的红外线，通过敞口端辐射加热固体发烟物质时，部分红外线可能会通过基体11侧面透射出去。红外线反射涂层的作用在于，将基体11侧面透射出去的红外线反射回基体11内部来加热位于基体11内部的固体发烟物质。这样，一方面提升了红外电热层12发出的红外线的有效利用率，提高了加热效率；另一方面可阻止热量由基体11侧面向远离基体11侧面方向的传导。
在该示例中，红外线反射涂层包括金属、金属氧化物中的至少一种。具体地，可为金、银、镍、铝、金合金、银合金、镍合金、铝合金、金的氧化物、银的氧化物、镍的氧化物、铝的氧化物、氧化钛、氧化锌和二氧化铈中的一种或多种制作而成。红外线反射涂层的厚度在0.3μm-200μm之间。
在另一种示例中，加热器还包括形成在基体11侧面上的绝热膜层，用于至 少部分的阻止热量由基体11侧面向远离基体11侧面方向的传导
在该示例中，绝热膜层的导热系数小于0.2W/(m·K)，优选的为小于0.1W/(m·K)，更优选的为小于0.05W/(m·K)，进一步优选为0.02-0.04W/(m·K)。
在该示例中，绝热膜层包括隔热材料，隔热材料可以为隔热胶、气凝胶、气凝胶毡、石棉、硅酸铝、硅酸钙、硅藻土或氧化锆等。
实施方式二
图6是本申请实施方式二提供的一种烟具100，烟具100包括吸嘴101、壳体102、实施方式一所述的加热器以及电源。
吸嘴101，具有吸嘴端和敞口端；敞口端与壳体102的一端通过可以拆卸的方式连接，吸嘴端设有出气口。
壳体102的侧壁上开设有若干进气孔，气流从进气孔流入，经过加热器的基体11的敞口端时，将加热器生成的气溶胶带走，从吸嘴端的出气口流出。壳体102的底壁上具有充电接口，通过充电接口可对烟具100进行充电或升级，以保证烟具100的持续使用。壳体102的后壁上设置有开关按键和指示灯，开关按键用于启动或关闭烟具100，指示灯用于指示烟具100的状态信息，例如：烟具100的工作状态、电池电量等等。
加热器的具体结构可参考实施方式一所述内容，在此不作赘述。加热器设置在壳体102内靠近吸嘴101的一端。
电源设置在壳体102内远离吸嘴101的一端。电源包括控制电路和电池，电池与控制电路电连接。
烟具100还包括温度传感器，例如：NTC温度传感器，用于检测基体11的实时温度，并将检测的实时温度传输到控制电路，控制电路根据该实时温度调节流经红外电热层12上的电流的大小。具体的，当NTC温度传感器检测到基体11内的实时温度较低时，譬如检测到基体11内侧的温度不到150℃时，控制电路控制电池输出较高的电压给电极，进而提高红外电热层12中馈入的电流，提高固体原料的加热功率，减少用户抽吸第一口所要等待的时间。当NTC温度传 感器2检测到基体11的温度为150℃-200℃时，控制电路控制电池输出正常的电压给电极。当NTC温度传感器检测到基体11的温度在200℃-250℃时，控制电路控制电池输出较低的电压给电极；当NTC温度传感器检测到基体11内侧的温度在250℃及以上时，控制电路控制电池停止输出电压给电极。
