实施方式一
如图1所示，为本申请实施方式一所提供一种加热器，所述加热器1包括基体11、第一红外电热涂层12以及导电模块(13、14)。
基体11内部形成有适于收容气溶胶形成基质的腔室。
具体地，基体11具有相对其长度方向的第一端111和第二端112，基体11沿第一端111和第二端之间112的纵向延伸并且内部中空形成有适于收容气溶胶形成基质的腔室。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，腔室即为贯穿基体11中部的圆柱体状孔，孔的内径略大于气溶胶形成制品或吸烟制品的外径，便于将气溶胶形成制品或吸烟制品置于腔室内对其进行加热。
基体11可以由石英玻璃、陶瓷或云母等耐高温且透明的材料制成；也可以由其它具有较高的红外线透过率的材料制成，例如：红外线透过率在95％以上的耐高温材料；还可以由耐高温且非透明的材料制成，具体地在此不作限定。
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。气溶胶形成基质可以是固体或液体或包括固体和液体组分。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。
在前面的叙述中已提到，现有烟具中远红外涂层涂覆在基体的外表面，通电后的远红外涂层发出的远红外线在穿透基体时会存在热量损失的现象。为了避免该现象，本示例中，第一红外电热涂层12涂覆在基体11的内表面上。
第一红外电热涂层12在通电情况下能够产生热能，进而生成一定波长的红外线，例如：8μm～15μm的远红外线。当红外线的波长与气溶胶形成基质的吸收波长匹配时，红外线的能量易于被气溶胶形成基质吸收。本示例中，对红外线的波长不作限定，可以为5μm～15μm的红外线，优选的为8μm～15μm的远红外线。
第一红外电热涂层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基体1的内表面上，然后烘干固化一定的时间，第一红外电热涂层12的厚度为30μm-50μm；当然，第一红外电热涂层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基体1的内表面上；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；第一红外电热涂层12还可以是现有的其他材料涂层。
在一示例中，加热器1还包括涂覆在第一红外电热涂层12上的保护层(附图未示出)。保护层可以为聚四氟乙烯层、釉层中的一种或两种的组合，或者为其他耐高温材料制成的保护层。保护层可避免例如气 溶胶形成制品或吸烟制品进出腔室造成的第一红外电热涂层12的磨损。
在一示例中，加热器1还包括设置在第一红外电热涂层12上的保护结构件。请参考图2所示，所述保护结构件可以为设置在所述基体的内表面上的凸块15，凸块15使得第一红外电热涂层12和气溶胶形成基质之间形成小于1mm的间隙，进而可避免例如气溶胶形成制品或吸烟制品进出腔室造成的第一红外电热涂层12的磨损。需要说明的是，凸块15的数量在此不作限定，可以为多个，可以设置在所述基体的内表面上的任何位置。还需要说明的是，保护结构件并不限于图2所示的凸块15，例如：可以为使得第一红外电热涂层12和气溶胶形成基质之间形成小于1mm的间隙的隔离件，该隔离件设置在所述基体的内表面上，隔离件的形状和大小可与气溶胶形成基质以及腔室相匹配，例如：圆柱体状、且为中空的隔离支架。
导电模块包括设置于基体11上的第一导电部13和第二导电部14，第一导电部13和第二导电部14均与第一红外电热涂层12电性连接；导电模块需要与第一红外电热涂层12紧密结合，保证通电时电流可以从第一导电部13经第一红外电热涂层12流到第二导电部14上，避免存在间隙而导致部分第一红外电热涂层12不通电无法发出红外线，进而影响加热器对腔室内的气溶胶形成基质进行加热。
由于第一红外电热涂层12涂覆在基体11的内表面上，第一导电部13和第二导电部14均包括设置在基体11的内表面上的导电部涂层段、设置在基体11的外表面上的导电部电极段、以及与导电部涂层段和导电部电极段连接的导电部连接段。
以第一导电部13为例，请参考图1所示，第一导电部13包括设置在基体11的外表面上的导电部电极段131(图中灰色部分所示)、设置在基体11的内表面上的导电部涂层段132(图中黑色部分所示)、以及与导电部电极段131和导电部涂层段132连接的导电部连接段133(图中白色部分所示)；其中导电部涂层段132主要用于与第一红外电热涂层12电性连接，导电部电极段131主要用于与外部电极电性连接，导电部连接段133用于分别与导电部电极段131和导电部涂层段132电性 连接。图1中，导电部连接段133沿着基体11的径向方向(即垂直于基体11的外表面或者内表面的方向)横跨在基体11上。需要说明的是，导电部连接段133可与导电部电极段131合为一体。
在本示例中，第一导电部13和第二导电部14可以为通过浸渍方式涂覆在基体11端部上的导电涂层，导电涂层为金属涂层或导电胶带等，金属涂层可以包括银、金、钯、铂、铜、镍、钼、钨、铌或上述金属合金材料。第一导电部13和第二导电部14也可以为套接在基体1靠近第一端和第二端位置的导电件，导电件包括但不限于金属导电片，例如铜片、钢片等等。
请参考图3所示，为一种示例的圆环形状导电件。该圆环形状导电件的外径(图中A所示)略大于基体11的外径，圆环形状导电件的内径(图中B所示)略小于基体11的内径；圆环形状导电件的内径和外径之间具有一凹槽(图中a所示)，基体11的壁可嵌入在该凹槽中。内外径的设置保证了圆环形状导电件套接在基体11上且与第一红外电热涂层12紧密贴合。
请参考图4所示，在一种示例中，加热器1还包括涂覆在基体11的外表面上的反射涂层15。
在该示例中，第一红外电热涂层12生成的红外线，部分红外线会通过基体11的内表面反射到待加热的气溶胶形成基质被吸收，部分红外线可能会通过基体11透射出去。反射涂层15的作用在于，将基体11透射出去的红外线反射回基体11内部来加热位于基体31内部的气溶胶形成基质。这样，一方面提升了第一红外电热涂层12发出的红外线的有效利用率，提高了加热效率；另一方面可起到隔热的效果，避免烟具的外壳温度过高，降低用户体验。
在该示例中，反射涂层15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、镍的氧化物和铝的氧化物、氧化钛、氧化锌、二氧化铈中一种或多种制作而成。反射涂层15的厚度在0.3μm-200μm之间。
在一种示例中，加热器1还包括呈中空状的隔热管(附图未示出)；
隔热管设置在基体11的外围。隔热管可以避免大量的热量传递到烟具外壳上而导致用户觉得烫手。
在该示例中，隔热管包括隔热材料，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、氧化锆等。所述隔热管也可以包括真空隔热管。
在一种示例中，加热器1还包括固定在基体11上的温度采集模块(附图未示出)；温度采集模块用于采集基体11的温度数据，便于对加热器1的温度进行控制。
在该示例中，温度采集模块包括温度传感器和/或数字型温度检测模块，温度传感器包括但不限于负温度系数(Negative Temperature Coefficient，简称NTC)、正温度系数(Positive Temperature Coefficient，简称PTC)等温度传感器。数字型温度检测模块为数字输出类型的温度检测模块，具体地可参考现有技术，在此不作限定。
在一种示例中，加热器1还包括形成于基体11的外表面的第二红外电热涂层16。请继续参阅图1和图2，
第二红外电热涂层16和第一红外电热涂层12均耦接于第一导电部13与第二导电部14之间，进而可通过第一导电部13和第二导电部14对第二红外电热涂层16和第一红外电热涂层14供电。需要说明的是，第二红外电热涂层16与第一红外电热涂层14的结构与功能相似，可参考第一红外电热涂层14的相关描述，在此不再赘述。
在该示例中，第一红外发射涂层14和第二红外发射涂层16分别是完全包覆基体11的外表面和内表面设置的，即第一红外发射涂层14和第二红外发射涂层16沿径向方向均是与基体11完全重叠的。这样可以保证对接收于腔室内的气溶胶形成基质辐射的红外线是能完全包围气溶胶形成基质的轴向方向的360度辐射，以确保对气溶胶形成基质的加热是均匀的。
具体，第一导电部13被构造成在基体11内表面靠近的第一端111的位置与第一红外电热涂层12电连接、以及在基体11外表面靠近第一 端111的位置与第二红外电热涂层16电连接；第二导电部14被构造成在基体11内表面靠近第二端112的位置与第一红外电热涂层12电连接、以及在基体11外表面靠近第二端112的位置与第二红外电热涂层16电连接。
在该示例中，第一导电部13包括形成于基体11的内表面的第一部分(图未示)、形成于基体11外表面的第二部分(图未示)以及形成于基体11的第一端111的第三部分(图未示)。在实施中，第一部分至少部分与第二红外电热涂层16是重叠的，进而与第二红外电热涂层16导电；第二部分至少部分与第一红外电热涂层12是重叠的，进而与第一红外电热涂层12电连接；第三部分沿径向方向的两侧分别是与第一部分和第二部分接合的。
进一步在实施中，第一部分、第二部分和第三部分是连续并形成的一个导电整体；第一部分和第二部分均是分别形成与基体11的外表面和内表面上的环形形状。
与第一导电部13类似，第二导电部14同样包括一体导电的第四部分(图未示)、第五部分(图未示)和第六部分(图未示)。
进而在使用中，通过将第一导电部13和第二导电部14分别连接至电源时，第一红外电热涂层12和第二红外电热涂层16在电结构上是并联的，进而降低了第一红外电热涂层12和第二红外电热涂层16的整体电阻，在电源的输出电压一定时增加了红外发射的效率。
进一步在优选的实施中，第一红外电热涂层12具有与第二红外电热涂层16不相同的红外发射的波长和效率。具体实施中气溶胶形成基质中不同的有机成分，而这些不同的有机成分各自具有不同最适的红外吸收峰；比如气溶胶形成基质中尼古丁的最适红外吸收波长与形成气雾的湿润剂的甘油和蔬菜甘油是不同的。因而在实施中，优选将第一红外电热涂层12与第二红外电热涂层16分别发出针对以上不同的成分的发射谱，当然各自发射谱的峰值波长范围是不同的，从而促进加热的效率。比如图5和图6分别示出了由两种不同的材料制备的第一红外电热涂层12和第二红外电热涂层16分别在供电后自身温度升高到一定温度时辐 射的红外发射谱图；从图5和图6中可以看出第一红外电热涂层12和第二红外电热涂层16各自发射谱具有不同的WLP(峰值波长，辐射功率最大处所对应的波长)，分别可以适于气溶胶形成基质中不同的有机成分的最适吸收波长范围。
基于避免使用中气溶胶形成基质于腔室内接收和移除操作对第二红外电热涂层16的磨损，实施中第二红外电热涂层16上还可以形成一可透红外的保护层，保护层可以采用可透红外的氧化锆陶瓷纸、玻璃、聚四氟乙烯、釉等制备。
或者在其他可变示例中，第一红外电热涂层12外还可以设置或形成一反射红外线的膜或涂层，比如可以是金、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；将红外加热管工作中向外辐射的红外线反射至腔室内，提升红外线的利用效率。

烟具100还包括主控制电路板3和电池7。固定壳62包括前壳621与后壳622，前壳621与后壳622固定连接，主控制电路板3和电池7均设置在固定壳62内，电池7与主控制电路板3电性连接，按键4凸设在外壳61上，通过按压按键4，可以实现对基体11内表面上的第一红外电热涂层12的通电或断电。主控制电路板3还连接有一充电接口31，充电接口31裸露于底盖64上，用户可以通过充电接口31对烟具100进行充电或升级，以保证烟具100的持续使用。
烟具100还包括隔热管5，隔热管5设置在固定壳62内，隔热管5套设在基体11外，隔热管5可以避免大量的热量传递到外壳61上而导致用户觉得烫手。具体的，隔热管5内还可涂覆有红外线反射涂层，以将基体11上的第一红外电热涂层12发出的红外线反射回基体11内部来加热位于腔室内的气溶胶形成基质，提高加热效率。红外线反射涂层与前述反射涂层15类似，在此不作赘述。
烟具100还包括NTC温度传感器2，用于检测基体11的实时温度，并将检测的实时温度传输到主控制电路板3，主控制电路板3根据该实时温度调节流经第一红外电热涂层12上的电流的大小。具体的，当NTC温度传感器2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，主控制电路板3控制电池7输出较高的电压给导电模块，进而提高第一红外电热涂层12中馈入的电流，提高气溶胶形成基质的加热功率，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，主控制电路板3控制电池7输出正常的电压给导电模块11。当NTC温度传感器2检测到基体11的温度在200℃-250℃时，主控制电路板3控制电池7输出较低的电压给导电模块；当NTC温度传感器2检测到基体11内侧的温度在250℃及以上时，主控制电路板3控制电池7停止输出电压给导电模块。
