下面结合附图和实施例对本申请进行详细的说明。
请参阅图1、图2和图3，图1提供了第一实施例中加热组件100的一种结构示意图，图2为图1的加热组件100沿A-A向的剖视结构示意图，图3为图1的加热组件100沿其轴向方向展开的外侧壁的结构示意图。
本申请提供一种加热组件100，该加热组件100用于在通电时加热收容在该加热组件100内的气溶胶形成基质；其中，气溶胶形成基质具体可为植物草叶类基质或膏状基质等，并且植物草叶类基质还可以进一步添加香气成分。气溶胶形成基质可以包裹在铝箔或纸张等内部，一起使用。
具体的，加热组件100包括发热体110、第一电极120和第二电极130。
其中，发热体110用于收容气溶胶形成基质，且发热体110包括发热材料。该发热体110既可对容置其中的气溶胶形成基质进行支撑，又能够在通电时发热，并对收容于其中的气溶胶形成基质加热，从而形成供用户使用的气溶胶。
第一电极120用于与正极导线连接，第二电极130用于与负极导线连接，以使发热组件能接收外部电源提供的电力，从而使发热体110通电发热。发热体110具有外侧面110a和内侧面110b，导电的第一电极120与导电的第二电极130间隔设置于发热体110的内侧面110b，并通过一导电红外发热层电连接。在其他实施方式中，第一电极120和第二电极130也可以设于发热体110的外侧面110a，不限于只设置在发热体110的内侧面110b。
第一电极120具有第一连接部121，第一连接部121用于与正极导线连接；第二电极130具有第二连接部131，第二连接部131用于与负极导线连接。其中，第一连接部121与第二连接部131间隔设置于发热体110的同一端。其中，发热体110的同一端是指发热体110的第一端或发热体110的第二端；具体的，以垂直于发热体110的轴向方向且穿过所述发热体110沿其轴向方向的中心点所在平面为界限，位于该平面一侧的部分发热体110为发热体110的第一端110c，位于该平面另一侧的部分发热体110为发热体110的第二端110d。具体的，发热体110为中空柱状，具有相对的第一端110c和第二端110d，第一连接部121与第二连接部131间隔设置于发热体110的第一端110c。从而，正极导线和负极导线均 能在发热体110的同一端分别与第一连接部121和第二连接部131连接。在其他实施例中，也可以是第一连接部121与负极导线连接，第二连接部131与正极导线连接。
第一电极120和第二电极130可以是涂覆于发热体110的内侧面110b的导电涂层，导电涂层可以是金属涂层、导电银浆或者导电胶带等，也可以是设于发热体110的内侧面110b的金属导电片或沉积在发热体110的外侧面110a的金属等，例如金膜、铝膜或铜膜。
加热组件100通过将用于与正极导线连接的第一连接部121和用于与负极导线连接的第二连接部131设于发热体110的内侧面110b的同一端，使得正极导线和负极能够在发热体110的同一端进行接线，无需正极导线或负极导线进一步走线至另一端以与相应的电极连通。相比于将第一连接部121和第二连接部131设置在发热体110的相对两端，使得正极导线和负极导线需要进行两端接线的方案，不仅大大简化了导线的走线路径，减小了导线的长度，且有效降低了制作成本及难度。
发热体110可以整个采用导电材料制备，例如导电陶瓷，也可以包括绝缘基体和设置于绝缘基体表面的导电红外发热层。在一种实施方式中，发热体110包括基体111和红外发热层112。
其中，基体111具有一端开口11111的收容腔1111，收容腔1111用于从开口11111收容气溶胶产生基质。具体的，开口11111的口径可大于或对应于气溶胶产生基质的外径，且收容腔1111的内径也大于或对应于气溶胶产生基质的外径，以使气溶胶产生基质能从开口11111插入或退出收容腔1111的内部。另外，在一种实施例中，气溶胶产生基质的外侧壁与收容腔1111的内侧壁可以具有一定的间隙，以使气溶胶产生基质能更容易插入或退出收容腔1111。
进一步地，在一实施例中，开口11111的口径可与收容腔1111的内径一致；在另一实施例中，开口11111的口径可小于收容腔1111的内径，且开口11111的中轴线与收容腔的中轴线重合，以在气溶胶产生基质通过该开口11111收容于收容腔1111内时，气溶胶产生基质与收容腔1111的内壁面间隔设置，避免气溶胶产生基质对位于收容腔1111的内壁面上的第一电极120和/或第二电极130造成破坏。
其中，基体111可以是中空管状，进一步地，在第一实施例中，基体111为中空圆柱体，收容腔1111为圆柱状。且基体111的侧壁的壁厚为固定值，以使发热体110能均匀地对气溶胶产生基质加热。第一连接部121和第二连接部131均沿着基体111的周向延伸形状弧形，优选地，第一连接部121和第二连接部131的长度相同，且沿着基体111轴向位于相同高度。
第一电极120和第二电极130设于基体111的内侧面110b，基体111具有相对的第一端110c和第二端110d，第一连接部121与第二连接部131间隔设于收容腔1111的内侧面110b的同一端。基体111可以是石英玻璃、陶瓷或云母等耐高温的绝缘材料，以防止第一电极120和第二电极130短路，当基体为石英玻璃时，其可以选用透明度80％以上的石英玻璃。
红外发热层112在通电时能产生红外波，以加热气溶胶产生基质。具体的，红外发热层112可环绕收容腔1111的内侧面110b设置，并分别与第一电极120和第二电极130连接；在第一电极120和第二电极130通电后，位于第一电极120和第二电极130之间的红外发热层112有电流通过，进而产生红外波。红外发热层112可以为金属层、导电陶瓷层或导电碳层。红外发热层112的形状可以为连续的膜状，多孔的网状或条状。其中，红外发热层112的材料、形状和大小可以根据需要进行设置。
其中，将红外发热层112设于基体111的内侧面110b，与红外发热层112设于基体111的外侧面110a的方案相比，红外发热层112与气溶胶产生基质的距离更近，且红外发热层112产生的红外波无需经过基体111侧壁的传导，即可直接对气溶胶产生基质进行加热，从而能够有效避免出现红外波经过基体111侧壁传导造成热量损失的问题，进而有效提高了红外发热层112对气溶胶产生基质的热传递效率。
在一具体实施例中，红外发热层112可以为红外发热膜，红外发热膜通电时辐射红外线，以加热收容腔1111中的气溶胶产生基质。可以理解的是，在红外发热膜通电时，红外发热膜发射的红外线无需穿过基体111的侧壁，可直接对收容腔1111内的气溶胶产生基质进行加热，提高了红外辐射的效率。其中，红外加热波长2.5um～20um，针对加热气溶胶形成基质的特点，通常加热温度需要350℃以上，能量辐射极值主要在3～5um波段。
其中，由于红外发热膜产生的红外线中，部分红外线朝向基体111外侧发射，使得红外发热膜产生的红外波不能被充分利用；为了解决该问题，在一种实施方式中，加热组件100还包括红外反射层140。红外反射层140设置于基体111的外侧面110a，用于反射所述红外发热膜发射的红外线；具体的，红外反射层140用于反射红外发热膜朝向基体111外侧发射的红外线，以使该部分红外线能够被反射回基体111的内部，并对气溶胶产生基质进行红外辐射加热，从而有效提高红外发热膜的加热效率。
在一实施例中，红外反射层140可以设于基体111的全部外侧面110a上，也可以设于基体111的部分外侧面110a上；在一具体实施例中，红外反射层140的至少部分与红外发热膜相对位置，以反射红外发热膜发射的红外线。
具体的，红外反射层140可以是耐高温的红外反射膜，红外反射膜涂覆于基体111的外侧面110a上。
请参考图4、图5和图6，图4提供了第二实施例中加热组件100的一种结构示意图，图5为图4的加热组件100沿B-B向的剖视结构示意图，图6为图4的加热组件100沿其轴向方向展开的外侧壁的结构示意图。
在一种实施方式中，该发热体110还可包括限位件113，限位件113设于基体111上，用于限位气溶胶产生基质的径向方向的位移，以使气溶胶产生基质在插入收容腔1111的过程中，气溶胶产生基质的外侧面110a与收容腔1111的内侧面110b之间具有间隙，从而在气溶胶产生基质和收容腔1111之间形成气道，便于调整气溶胶产生基质的抽吸阻力。
在一实施例中，限位件113可以设于基体111具有开口11111的一端，且限定形成限位口1131；限位口1131与收容腔1111连通，且限位口1131的口径小于收容腔1111的内径，气溶胶产生基质具体通过该限位口1131收容于收容腔1111，以使气溶胶产生基质通过限位口1131限位于收容腔1111时，气溶胶产生基质的外侧面110a与收容腔1111的内侧面110b之间具有间隙，从而在气溶胶产生基质和收容腔1111之间形成气道，便于调整气溶胶产生基质的抽吸阻力。
具体的，在该实施例中，限位口1131的口径可大于气溶胶产生基质的外径，以使气溶胶产生基质能通过该限位口1131顺利插入或退出收容腔1111。
具体的，限位件113可以与基体111为同一材料，且一体成型，以简化发热体110的制造流程。当 然，限位件113也可以与基体111为不同的材料。
在一种实施方式中，限位口1131的中心与收容腔1111的中轴位于同一条直线上，以使限位口1131对气溶胶产生基质在收容腔1111中的径向方向限位时，气溶胶产生基质的外侧壁与收容腔1111的内侧壁之间的距离处处相等。从而，收容腔1111的内侧壁上的红外发热层112对气溶胶产生基质的周向均匀地加热，有利于气溶胶产生基质加热过程中热量分布均匀。
在一种实施方式中，如图7所示，图7为气溶胶产生基质插入加热组件100的一种剖面结构示意图。限位件113设于基体111具有开口11111的端面上；在该实施例中，限位件113限定形成的限位口1131区别于收容腔1111的开口11111，且可位于收容腔1111的开口11111的上方位置；在气溶胶产生基质插入收容腔1111的过程中，气溶胶产生基质依次通过限位口1131、收容腔1111的开口11111进入收容腔1111。当然，在该实施例中，限位件113也可朝向收容腔1111内倾斜延伸，以在收容腔的开口11111处限定形成限位口1131，可以理解的是，在该实施例中，该限位口1131即收容腔1111的开口。
在另一实施方式中，参见图4和图5，限位件113可以设于收容腔1111的内侧面110b上并位于收容腔1111的端部；具体的，在该实施例中，限位件113的上端面可与基体111的侧壁的上端面平齐，并限定形成收容腔1111的开口11111；可以理解的是，在该实施例中，开口11111与限位口1131位于同一平面上，限位件113限定形成的限位口1131即为收容腔1111的开口11111。
在一实施例中，限位件113可为沿收容腔1111的周向延伸的凸环；参见图4，凸环可设置在收容腔1111的内壁面且环绕收容腔1111的内壁面一圈设置；在该实施例中，凸环背离收容腔1111的内壁面的中空区域形成为限位口1131。
在另一实施例中，限位件113可包括多个沿收容腔1111的周向方向间隔设置的凸块；优选地，多个凸块可沿收容腔1111的周向方向等间隔设置于基体111上，以使限位件113能有效地对气溶胶产生基质的多个径向方向进行限位。进一步地，多个凸块于收容腔1111的轴线方向上的高度相等，以在收容腔1111的同一轴向高度上形成限位口1131。
具体的，上述限位件113的形状可以是环状、圆弧状、点状、块状、条状等形状。例如可以是两个弧形的条块等间隔设置于收容腔1111的内侧面110b上；或者，三个块状的结构等间隔的设置于基体111的第一端110c的端面上，并在基体111的第一端110c形成限位口1131。需要说明的是，限位件113的数量、形状、结构和设置位置不限于以上提到的几种方式。
比如，在限位件113的数量为多个时，多个限位件113可以同时设于基体111的一端，也可以分别设于基体111的相对的两端，或者，多个限位件113可以沿轴线方向分布于收容腔1111的内部。例如，限位件113的数量可以为两个，其中一个限位件113设于基体111的第一端110c，另一个限位件113设于基体111的第二端110d，以在基体111的两端形成两个限位口1131，使气溶胶产生基质相对的两端均能被限位件113限位。
收容腔1111内壁上的电路图可以根据需要设计成各种形式。在一种实施方式中，如图8所示，图8为第三实施例中加热组件100沿其轴向方向展开的外侧壁的结构示意图。其中，第一连接部121为环状，且沿着发热体110的周向延伸并具有缺口1211，即第一连接部121在周向方向未形成闭环。第二连接部 131位于第一连接部121远离第一端110c端面的位置，从而负极导线能通过缺口1211与第二连接部131相连。第一连接部121形成缺口1211，能使得负极导线不与第一连接部121接触并与第二连接部131连接，防止负极导线与第一连接部121接触短路，便于走线。
图8出示了第一连接部121与第二连接部131的三种纵向位置关系。第二电极130在a位置时，第二连接部131沿发热体110的轴向方向与缺口1211完全错位；第二电极130在b位置时，第二连接部131与缺口1211在发热体110的轴线方向上正对设置；第二电极130130在c位置时，第二连接部131沿发热体110的轴线方向与缺口1211部分错位。第二电极130设于b位置时，导线更容易通过缺口1211与第二连接部131连接，导线的走线路径更简单。
在一种实施例中，如图3所示，第一连接部121和第二连接部131均可以视为具有缺口的圆环状，其中，第一连接部121和第二连接部131中的一个设置于另一个的缺口处。例如，全部的第二连接部131沿发热体110的轴线方向通过缺口1211暴露，且第二连接部131位于缺口1211的位置，并在发热体110的轴向方向上与第一连接部121的高度一致。进一步的，第一连接部121和第二连接部131与发热体110第一端110c的端面平齐。由此，正极导线和负极导线能直接与第一连接部121和第二连接部131连接，导线的走线路径更简单，简化了加热组件100的走线方式。
在一种实施方式中，请参考图3，第一电极120还包括至少一个第一延伸部122，第一延伸部122的一端与第一连接部121连接，另一端自第一连接部121朝向发热体110的第二端110d延伸。第二电极130还包括至少一个第二延伸部132，第二延伸部132的一端与第二连接部131连接，另一端自第二连接部131朝向发热体110的第二端110d延伸。第一延伸部122和第二延伸部132可以延伸至靠近第二端110d的位置，也可以延伸至第二端110d的端面。其中，第一延伸部122和第二延伸部132用于在红外发热层112上形成或定义至少一个发热区。第一延伸部122与第二延伸部132间隔设置，相邻的第一延伸部122和第二延伸部132之间的红外发热层112形成一个发热区。第一电极120和第二电极130通电后，第一延伸部122和第二延伸部132之间的发热区有电流通过，发热区发热加热气溶胶产生基质。第一连接部121与第一延伸部122的材料可以相同，通过印刷或沉积一次形成。第二连接部131与第二延伸部132的材料可以相同，通过印刷或沉积一次形成。本申请中，连接部与延伸部的区别在于连接部的尺寸可以比延伸部的尺寸大，便于与外接导线焊接或粘结固定。
其中，第一延伸部122和第二延伸部132的延伸路径可以是直线型、折线形、曲线型或者不规则的形状；第一延伸部122和第二延伸部132的延伸方向可以沿轴向方向延伸，也可以与轴向方向呈任一角度方向延伸，或者沿周向方向螺旋延伸。
在一种实施方式中，第一延伸部122和第二延伸部132平行，均沿发热体110的轴向方向延伸，且均呈直线型，以使第一延伸部122和第二延伸部132之间的加热区的形状规则，有利于使第一延伸部122和第二延伸部132之间的电流分布均匀，进而使各个加热区对气溶胶产生基质的加热均匀。
在第一实施例中，第一连接部121与第二连接部131均匀地周向分布在基体111的第一端110c。第一延伸部122和第二延伸部132的数量均可为一个。第一延伸部122的一端设于第一连接部121的中部，另一端延伸至基体111的第二端110d的端面。第二延伸部132的一端设于第二连接部131的中部，另 一端延伸至基体111的第二端110d的端面。第一延伸部122和第二延伸部132间隔设置于圆柱状基体111的同一直径的相对两端，均沿发热体110的轴向方向延伸，且均可呈直线型；当然，在其他实施例中，第一延伸部122和/或第二延伸部132也可呈弯曲型，本申请对此并不加以限制，只要二者不相交即可；具体的，第一延伸部122和第二延伸部132沿周向均匀地分布，并将红外发热层112分隔为两个形状和大小相同的两个发热区，以使两个发热区能均匀地对气溶胶产生基质加热。第一电极120和第二电极130通电后，电流从第一延伸部122沿相反的两个方向向第二延伸部132流动，电流流经两个发热区，两个发热区发热对气溶胶产生基质加热。这种发热组件的电路分布简单，且实现了同一端出现的接线方式，使得发热组件的走线路径较为简单，降低了制作成本和难度。
在一种实施方式中，请参考图9，图9提供了第四实施例中加热组件100沿其轴向方向展开的外侧壁的结构示意图。第二电极130还包括第三连接部133，第三连接部133用于与负极导线连接。第三连接部133设于发热体110的第二端110d，并与第二延伸部132连接。第三连接部133可以沿着发热体110的第二端110d周向延伸形成闭环状、具有缺口的环状或弧状。在接线时，正极导线与第一端110c的第一连接部121连接，负极导线既可以与第一端110c的第二连接部131连接，也可以与第二端110d的第三连接部133连接。因此，设置第三连接部133能使得加热组件100在实现单侧接线的同时，也能实现双侧接线，该加热组件100提供了多种走线的方式，可以根据需要选择加热组件100的接线方式。在其他实施例中，也可以是第一电极120包括第三连接部133，第三连接部133用于与正极导线连接，同样能实现发热组件既能单侧接线，也能双侧接线的功能。
在一种实施方式中，第一连接部121、第二连接部131和第三连接部133中的至少一个与发热体110的红外发热层112间隔设置。当红外发热层112与第一连接部121、第二连接部131和第三连接部133中的至少一个相连接时，部分电流会从第一连接部121流向第二延伸部132，或者，从第一延伸部122流向第二连接部131，或者，从第一延伸部122流向第三连接部133，使得发热区电流的走向不规律，发热区发热不均匀。优选地，第一连接部121、第二连接部131和第三连接部133均与发热体110的红外发热层112间隔设置，以限定发热区的电流流向方向为周向，以使发热区电流的走向规律，使得发热区的发热更加均匀，对气溶胶产生基质加热更加均匀。进一步地，红外发热层112的边缘与第一延伸部122靠近第二端110d的端部平齐，第一延伸部122将红外发热层112完全分隔为形状和面积相同的两个间隔的发热区，以使发热区的电流的走向更加规律。可以理解，当没有第三连接部133时，第一连接部121和第二连接部131均与发热体110的红外发热层112间隔设置，且与发热体110的红外发热层112的间距相同。
在一种实施方式中，请参考图10，图10提供了第五实施例中加热组件100沿其轴向方向展开的外侧壁的结构示意图。第一电极120包括与第一连接部121连接的多个第一延伸部122，第二电极130包括与第二连接部131连接的多个第二延伸部132。相邻的第一延伸部122和第二延伸部132间隔设置，相邻的第一延伸部122和第二延伸部132之间形成发热区。进一步地，多个第一延伸部122与多个第二延伸部132交替间隔设置，以将红外发热层112周向分隔形成偶数个发热区，每个发热区具有部分红外发热层112。
当第一延伸部122和第二延伸部132的数量相同时，第一延伸部122和第二延伸部132交替间隔设置，能使红外发热层112被全部利用，并被分隔为偶数个发热区为气溶胶产生基质加热。当第一延伸部122和第二延伸部132的数量为不同时，会出现两个第一延伸部122相邻或者两个第二延伸部132相邻的情况，相邻的两个第一延伸部122的电极为同一极性，相邻的两个第二延伸部132的电极为同一极性，其之间不能导通电流，即相邻的两个第一延伸部122或相邻的两个第二延伸部132之间不能形成发热区，红外发热层112不能被全部利用。因此，当第一延伸部122和第二延伸部132的数量相同时，第一延伸部122和第二延伸部132交替间隔设置，能使红外发热层112被全部利用，避免了部分红外发热层112出现不能形成发热区的情况。
进一步地，任意相邻的第一延伸部122和第二延伸部132的间隔距离相同，且第一延伸部122和第二延伸部132沿轴线方向延伸且呈直线型，以使多个第一延伸部122和多个第二延伸部132均匀地周向分布在发热体110的外侧面110a上，相邻的第一延伸部122和第二延伸部132之间的发热区的形状和大小相同，每个发热区的等效电阻相同。因此，能使得通电后各个发热区发出的热量大小基本相同，各个发热区能均匀地对气溶胶产生基质的各个方向加热。
第一延伸部122和第二延伸部132的数量为多个的时候，第二电极130包括第三连接部133。第一连接部121用于与正极导线连接的同时，还用于连接多个第一延伸部122；第三连接部133用于与负极导线连接的同时，还用于连接多个第二延伸部132，即第一电极120和第二电极130形成插齿电极。优选的，第三连接部133与每一个第二延伸部132连接，且第三连接部133在加热体的第二端110d形成环状，以使每个发热区都能通电工作。
第五实施例中，第一延伸部122和第二延伸部132的数量均为两个。两个第一延伸部122分别位于第一连接部121的两端。一个第二延伸部132分别与第二连接部131和第三连接部133相连，另一个第二延伸部132设于两个第一延伸部122之间且仅与第三连接部133连接。第三连接部133环形设置在发热体110的第二端110d，并分别与两个第二延伸部132连接。两个第一延伸部122和两个第二延伸部132交替间隔设置，均沿发热体110的轴向方向延伸，且均呈直线型。两个第一延伸部122和两个第二延伸部132沿周向均匀地分布，并将红外发热层112分隔为四个形状和大小相同的发热区，以使四个发热区能均匀地对气溶胶产生基质加热。相比于电路将红外发热层112分隔为两个发热区的加热组件100，四个发热区的加热组件100中每个发热区的等效电阻更小，每个发热区的发热功率更大，加热组件100对气溶胶产生基质的加热效率更高。
请参考图11，图11提供了第六实施例中加热组件100沿其轴向方向展开的外侧壁的结构示意图。第六实施例中，第一延伸部122和第二延伸部132的数量均为一个。第一延伸部122、第二延伸部132和红外发热层112均沿发热体110的周向方向螺旋型延伸，并从发热体110的第一端110c延伸至第二端110d。
由于第一延伸部122和第二延伸部132发热体110的第一端110c螺旋延伸至第二端110d，第一延伸部122的两端均可以用作第一连接部121，第二延伸部132的两端均可以用作第二连接部131。或者，在第一端110c和第二端110d均设置第一连接部121和第二连接部131，且第一连接部121与第一延伸 部122的一端连接，第二连接部131与第二延伸部132的一端连接。
其中，红外发热层112位于第一延伸部122和第二延伸部132之间，并形成一个螺旋型发热区。优选的，第一延伸部122和第二延伸部132的螺旋延伸方向一致，且第一延伸部122和第二延伸部132之间的间隔距离处处相等，第一延伸部122和第二延伸部132均匀地分布在发热体110的外侧面110a，以使红外发热层112均匀地对气溶胶产生基质加热。
在一种实施方式中，如图12和图13所示，发热体110包括多个子发热体114，多个子发热体114配合能拼接成一个发热体110。多个子发热体114的内侧面110b上均设有电极，多个子发热体114拼接后，多个子发热体114的电极能拼接成发热体110的电路。发热体110可以包括多个大小相等，形状相同的多个子发热体114，也可以包括多个大小不同，形状不同的多个子发热体114。发热体110为中空圆柱体时，多个子发热体114可以是多个中空圆弧状的形状。图11提供了一种子发热体114的结构示意图。该实施例中，子发热体114为空心半圆柱状，两个空心半圆柱状的子发热体114可以拼接成一个完整的空心圆柱状的发热体110。
由于本申请将第一电极120、第二电极130以及红外发热层112均设于基体111的内侧面110b上，在发热组件的制造过程中，从外部不便于将电极和红外发热层112涂覆于收容腔1111中。因此，需要将发热体110分隔为多个子发热体114，将电极和红外发热层112涂覆于各个子发热体114上，最终将各个子发热体114拼接成完整的发热体110。
具体的，每一子发热体114的内侧面110b设有第一子连接部123和/或第二子连接部134，多个子发热体114上的第一子连接部123拼接形成第一连接部121，多个子发热体114上的第二子连接部134拼接形成第二连接部131。优选地，每一子发热体114的内侧面110b设有第一子连接部123和第二子连接部134，同一子发热体114的第一子连接部123和第二子连接部134分别通过延伸部与子发热体114的红外发热层112电连接，使得每一子发热体114的红外发热层112可以独立工作。即，多个子发热体114不仅拼接后能作为一个整体对气溶胶产生基质加热，也能不进行拼接，各自作为独立的发热体110，各自通电后对气溶胶产生基质加热。当多个子发热体114各自作为独立的发热体110对气溶胶产生基质加热，可以使用多组正负极导线分别连接每个子发热体114的第一子连接部123和第二子连接部134。
如图13所示，图13为第七实施例提供的两个如图11所示的子发热体114拼接成的发热体110的侧壁展开结构示意图。其中，发热体110包括第一子发热体115和第二子发热体116，第一子发热体115和第二子发热体116均为空心半圆柱状。第一子发热体115和第二子发热体116拼接后能形成一个空心圆柱状的发热体110。第一子发热体115的内侧面110b和第二子发热体116的内侧面110b均设有第一子连接部123、第二子连接部134、第一延伸部122和两个第二子延伸部1321。相邻的第一子发热体115上的第二子延伸部1321和第二子发热体116上的第二子延伸部1321形成一个第二延伸部132，第一子发热体115上的两个第二子延伸部1321和第二子发热体116上的两个第二子延伸部1321形成两个第二延伸部132。相邻的第一延伸部122和第二子延伸部1321之间形成一个发热区，以使第一子发热体115和第二子发热体116均能在通电时加热所述气溶胶产生基质。
进一步地，第一子发热体115的内侧面110b和第二子发热体116的内侧面110b均设有第三子连接 部1331，第三子连接部1331连接同一子发热体114的两个第二子延伸部1321。每个子发热体114上的第三子连接部1331拼接形成第三连接部133。设置第三子连接部1331能使得每个子发热体114上的电路在实现单侧接线的同时，也能实现双侧接线，该加热组件100提供了多种走线的方式，可以根据需要选择加热组件100的接线方式。
在一种实施方式中，加热组件100还可以包括第一导电弹片、第二导电弹片和第三导电弹片。优选地，第一导电弹片、第二导电弹片和第三导电弹片均设于多个子发热体114的拼接处。
多个子发热体114拼接的过程中，多个子发热体114的电极可能会接触不良，通过设置第一导电弹片、第二导电弹片和第三导电弹片，能将不同的子发热体114上的各个电极电连接，使得发热组件能正常工作，对气溶胶产生基质加热。
第一导电弹片设置在发热体110的内侧面110b上，与每一子发热体114上的第一子连接部123电连接。第一导电弹片的数量可以是多个，每个第一导电弹片连接相邻的两个第一子连接部123。具体的，第一导电弹片可以与每一子发热体114上的第一子连接部123接触连接，以使每一子发热体114上的第一子连接部123电连接。或者，第一导电弹片也可以与每一子发热体114上的第一延伸部123接触连接，以使每一子发热体114上的第一子连接部123电连接。
第二导电弹片设置在发热体110的内侧面110b上，与每一子发热体114上的第二子连接部134连通。第二导电弹片的数量可以是多个，每个第二导电弹片连接相邻的两个第一子连接部123。具体的，第二导电弹片可以与每一子发热体114上的第二子连接部134接触连接，以使每一子发热体114上的第二子连接部134电连接。或者，第一导电弹片也可以与每一子发热体114上的第二子延伸部1321接触连接，以使每一子发热体114上的第二子连接部134电连接。
在一种实施方式中，第三导电弹片设置在发热体110的内侧面110b上，与每一所述子发热体114上的第三子连接部1331连接，以使每一子发热体114上的第二子连接部134连通并电连接。第三导电弹片的数量可以是多个，每个第三导电弹片连接相邻的两个第三子连接部1331。

在一种实施方式中，固定机构150进一步包括第一固定件151和第二固定件152。第一固定件151套设在多个子发热体114的第一端110c，用于对多个子发热体114的第一端110c进行固定；第二固定件152套设在多个子发热体114的第二端110d，用于对多个子发热体114的第二端110d进行固定。第一固定件151和第二固定件152可以具有限位槽，多个子发热体114的第一端110c和第二端110d分别设于第一固定件151的限位槽和第二固定件152的限位槽中，以对多个子发热体114进行限位。
在第八实施例中，如图14所示，第一固定件151为圆柱形的上盖，第二固定件152为圆柱形的底座。发热体110包括两个子发热体114，上盖套设在两个子发热体114的一端，底座套设在两个子发热体114的另一端，以使两个子发热体114固定于上盖和底座中。进一步地，上盖和底座限位两个子发热 体114，并使两个子发热体114拼接为一个发热体110，以使发热体110通电后能对气溶胶产生基质进行加热。
在一种实施方式中，如图14所示，固定机构150还具有通孔153，通孔153的孔径小于发热体110的收容腔1111的内径。即，固定机构150还可以作为限位件113，对气溶胶产生基质在收容腔1111中的位置进行限位，以使气溶胶产生基质的外侧面110a与收容腔1111的内侧面110b之间具有间隙，从而在气溶胶产生基质和收容腔1111之间形成气道，便于调整气溶胶产生基质的抽吸阻力红外发热层。
图15为本申请一实施例提供的气溶胶产生装置200的结构示意图。本申请还提供一种气溶胶产生装置200，该气溶胶产生装置200可包括加热组件100和电源组件230。
其中，加热组件100具体可为上述任一实施例所涉及的加热组件100，其具体结构与功能可参见上述实施例中关于加热组件100的相关描述，且可实现相同或相似的技术效果，在此不再赘述。
其中，气溶胶产生装置200进一步可包括壳体210和安装座220。安装座220用于将加热组件100固定在壳体210上；具体的，安装包括安装主体，安装主体上设置有通孔153，加热组件100体插接在该通孔153中以与安装座220安装；在具体实施例中，通孔153的侧壁上还可设置有避让槽，正负极导线具体通过该避让槽伸入安装座220内以与发热体110上的远离安装座220的第一电极120和第二电极130连接。进一步地，安装主体上还设置有至少两个卡接部，安装座220具体通过卡接部以与气溶胶形成装置的壳体210固定。
其中，该气溶胶产生装置200还可包括控制器(图未示)，控制器分别与加热组件100和电源组件230连接，用于在接收到启动信号后控制电源组件230为加热组件100供电并控制加热组件100发热的功率、加热时长等。
其中，电源组件230与加热组件100连接，用于向加热组件100供电；且在一实施例中，电源组件230具体可包括可充电的锂离子电池。
本实施例提供的气溶胶产生装置200，通过设置加热组件100，加热组件100通过将用于与正极导线连接的第一连接部121和用于与负极导线连接的第二连接部131设于发热体110外侧面110a的同一端，使得正极导线和负极能够在发热体110的同一端进行接线，无需正极导线或负极导线进一步走线至另一端以与相应的电极连通。相比于将第一连接部121和第二连接部131设置在发热体110的外侧壁的相对两端，使得正极导线和负极导线需要进行两端接线的方案，不仅大大简化了导线的走线路径，减小了导线的长度，且有效降低了制作成本及难度。
以上仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请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，均同理包括在本申请的专利保护范围内。
