 本发明的最佳实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
如图1、图2所示，本发明一个优选实施例中的烘烤烟具包括筒状的烟筒1、和加热组件2，加热组件2包括加热件21、引线22和安装座23。
结合图1至图3所示，加热件21为片状，可脱出地插设到烟筒1内。加热件21包括在长度方向两相对的第一端A、第二端B，第一端A向外伸出设置，加热件21可由第一端A插入烘烤烟具的烟筒1内。
加热件21包括在宽度方向两相对的第一边C、第二边D，第一边C、第二边D分别设置有让加热件21的厚度在宽度方向向边缘逐渐减薄的避让部211。加热件21的中线位于烟筒1的中部，加热件21的宽度方向两相对边到烟筒1的内壁面的距离相当。
加热件21的两侧边逐渐减薄，在加热件21插入烟支3时，可以减缓加热件21的两侧边对烟草压力，可以让避让部211对应的两侧边的烟草不会受到大的挤压压缩，缓解侧端部烟草压力，提升烟草雾化效率。该避让部211还可以呈现平滑过渡，防止烟草在加热件21侧端面粘结。
加热件21包括在厚度方向两相对的第一侧E、第二侧F，避让部211包括在第一边C对应的第一侧E和第二侧F边缘设置的倒角、以及第二边D对应的第一侧E和第二侧F边缘的设置的倒角。
倒角包括斜角或圆角，第一边C的第一侧E、第二侧F边缘分别设置有倒角，第二边D的第一侧E、第二侧F边缘分别设置有倒角，，第一边C、第二边D的避让部211将加热件21的第一边C、第二边D形成圆角边或尖角边。
在其他实施例中，避让部211也可以只在第一边C对应的第一侧E或第二侧F边缘设置的倒角，以及只在第二边D对应的第一侧E或第二侧F边缘设置的倒角，将所述第一边C、第二边形成尖角边，方便一次冲压形成。
两相对边的避让部211平滑过渡，或者打磨光滑，或者上釉层，可以有效防止烟草在侧边粘结，缓解烟草积压。
再结合图4所示，加热件21包括金属材质的片状基材212、覆盖在片状基材212上的绝缘层213、以及设置于绝缘层213外侧的导电通路214，引线22与导电通路214连接，引线22向外引出，在引线22接电向导电通路214通电后导电通路214发热对烟草雾化。
优选地，加热件21的基材为金属或合金材质，片状基材212可以采用不锈钢或钛合金等通用金属材质，优选不锈钢，如430和304不锈钢。片状基材212的厚度通常为0.2-0.8mm，通过冲压成型或线切割形成，成本较低。金属材质的片状基材212上避让部211可以冲压形成，进一步节约成本。加热件21的长度、宽度等尺寸与其配套使用的卷烟烟支的直径和长度相配合，有利于烟草的充分的加热。
采用金属材质的片状基材212作为加热件21的主体，其具有高的韧性，从而可以有效防止加热件21在长期高温和装烟等机械冲击下出现断裂，同时金属材质的片状基材212良好的导热性能，保证了加热件21表面温度的均匀性，有利于加热不燃烧卷烟获得较佳的口感。
如图5、图7所示，根据稳态模拟实验表明，在相同的温度场，不锈钢比氧化锆等陶瓷加热件21周围超过215度的区域更大，因此雾化效率更高，口感更好。
优选地，片状基材212的第一端A这一端设有利于插入烟支3的尖头215，尖头215可以导引加热件21插入，减小插入时的阻力。
为了满足让导电通路214印刷到片状基材212上的工艺需求，片状基材212包括位于加热件21两相对边的避让部211之间的平整面2121，导电通路214印刷形成于平整面2121区域内。避让部211则由平整面2121的宽度方向两相对边向外设置。
绝缘层213为在片状基材212表面覆盖包含有氧化硅、氧化钙、氧化铝的玻璃浆料后在400-1000℃烧结形成，由于金属或合金材质的片状基材212导电，绝缘层213可以防止片状基材212与导电通路214之间短路。
绝缘层213通过喷涂或印刷的方式覆盖到片状基材212上，可以根据导电通路214与片状基材212间的耐压要求，设计绝缘层213的厚度，一般绝缘层213的厚度小于0.1mm。
为了防止金属材质的片状基材212在高温使用过程中氧化，优选地，片状基材212的两侧均覆盖有绝缘层213。导电通路214位于一侧的绝缘层213上，绝缘层213也可只在片状基材212的一侧设置，供导电通路214设置，当加热件21的基材为非金属不导电材质时，也可取消绝缘层213。
导电通路214用作电阻加热器，可以采用物理气相沉积或电镀或印刷等方式在绝缘层213上形成的导电层。
优选地，导电通路214包括发热电阻2141、以及与发热电阻2141电性连接的电连接部，发热电阻2141、电连接部沿片状基材212的长度方向排布，导电电极2142与外部电路连接。优选地，电连接部包括与发热电阻2141电性连接的两个导电电极2142。
引线22与导电电极2142连接，并沿加热件21的长度方向远离发热电阻2141的一端引出，即发热电阻2141、导电电极2142由第一端A向第二端B的方向排布，引线22由第二端B向外引出。
发热电阻2141可以为采用银-钯电阻浆料、钌-钯电阻浆料、铂浆、镍基浆料中的任一一种印刷后烧结形成。发热电阻2141的图案可以灵活设置，配合浆料特性，以及发热电阻2141的厚度，获得用于加热件21所需的合适阻值，加热件21的阻值一般在0.3-2.0Ω之间；发热电阻2141的厚度一般小于0.1mm，优选是小于20um。导电电极2142采用电阻率相对较低的银基浆料印刷后烧结形成。
引线22与外部电源通电时，发热电阻2141能够通电发热，引线22可以通过银铜焊料或纯银焊料或镍焊料在600-1100℃保护气氛下高温钎焊的方式与导电电极2142连接；引线22通过高温焊膏以锡焊方式将引线22连接于导电电极2142上，使用温度大于300℃。
由于金属材质的片状基材212导热性较好，为防止热量损失，导电电极2142所在的片状基材212的长度方向区间段上设有通孔2122，通孔2122可以隔离热量，减少向第二端B传递的热量。
由于导电电极2142对应的区段温度较低，烟草不能充分雾化，该处烟丝可以存储吸收一定量烟油，因此可防止或减少烟油从此处漏出。
加热件21插入烟草的发热电阻2141对应的区段与导电电极2142对应的区段存在一个较大的温度梯度，导电电极2142对应的区段温度相对较低，热量的耗散小，有利于能量的有效利用。
为了使发热电阻2141与外界的空气隔绝，进一步提高其使用寿命和稳定性，加热件21还包括覆盖在导电通路214外的隔离层216。
隔离层216为玻璃釉料烧制形成的釉料层，其厚度一般小于0.1mm。片状基材212的两侧均覆盖有隔离层216。釉料层使加热件21表面光滑，具有较小的粗糙度，减少烟草烘烤后烟渍、烟油的粘附，便于擦洗。在其他实施例中，也可只将隔离层216覆盖到导电通路214所在一侧。
优选地，如图6所示，为了利于加热件21插入到烟支3中，加热件21的第一端A到第二端B的宽度逐渐变宽，让加热件21呈宝剑形状，第一端A窄，结合避让部211的减薄结构，让加热件21插入时阻力较小，利于插入，还可有效减少烟草集聚在加热件21侧边上；加热件底部变宽有利于增加加热件21的强度，防止多次插拔烟支导致加热件折断。
通常，尖头215的宽度方向两相对边的夹角角度大于加热件21第二端B宽度方向两相对边的夹角角度。在其他实施例中，加热件21也可呈三角形。
再如图2所示，安装座23套设在加热件21的第二端B上，即套设在加热件21上引线22引出的一端，套设到电连接部上。在其他实施例中，安装座23也可为独立部件单独安装到加热件21上。
尖头215位于加热件21远离安装座23的一端，安装座23和尖头215分别位于加热件21的两相对端，在加热件21的尖头215一端插入烟筒1内后，安装座23会与烟筒1的外端相抵，限定加热件21的插入深度。
由于导电电极2142所在的片状基材212的长度方向区间段上设有通孔2122，减少了热量向第二端B传递，也就可以防止安装座23部位温度过高。
安装座23所在的第二端B端部到导电电极2142之间由于未设置加热区，产生有害气体的可能性会降低，且对安装座23的选材范围更广泛，降低成本。通常，安装座采用高分子聚合物注塑成型，常用的材质有聚醚醚酮、高温尼龙等。
可以理解地，上述各技术特征可以任意组合使用而不受限制。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
