Definitions
- the present application relates to the field of smoking articles, in particular to a heater and a smoking article including the heater.
- Smoking articles such as cigarettes and cigars burn tobacco to produce smoke during use. Attempts have been made to provide alternatives to these tobacco-burning articles by creating products that release compounds without burning. Examples of such products are so-called heat-not-burn products, which release compounds by heating tobacco rather than burning it.
- An existing low-temperature heating and non-burning smoking device mainly coats a far-infrared coating and a conductive coating on the outer surface of a base body, and the far-infrared coating after being energized emits far-infrared rays to penetrate the base body and cause aerosol in the base body.

- the heater of the first aspect for heating the aerosol-forming substrate to generate an aerosol.
- the coupling electrode in the non-coated area and arranging the coupling electrode at the same end of the base body, the external wire line is short, and the wire connected at one end is avoided.
- the need to pass through the hot area leads to the problem that the wire is easily damaged.

图5-图6是本申请实施方式提供的另一种加热器，与图3-图4不同的是，基体11的外表面包括第一非涂层区域1121和第二非涂层区域1122，第一非涂层区域1121紧邻基体11的远端B设置，第二非涂层区域1122紧邻基体11的近端A设置。
第一电极包括设置在第一非涂层区域1121内的第一藕接电极1132、 设置在第二非涂层区域1122内的第二藕接电极1133、自第一藕接电极1132轴向延伸至第二藕接电极1133的条形电极1131，条形电极1131部分位于涂层区域111内以与所述红外电热涂层形成电连接；

第一藕接电极1132、第一藕接电极1142以及第三藕接电极1152均间隔设置在第一非涂层区域1121内且位于基体11的远端B。条形电极1131、条形电极1141以及条形电极1151将红外电热涂层沿基体11周向方向分隔为两个独立的加热区域，即在图中的1111和1112所示的两个涂层区域上形成的两个红外电热涂层。
第一藕接电极1132、第一藕接电极1142以及第三藕接电极1152与电源藕接之后，通过控制两个独立的加热区域启动加热，可以实现对所述气溶胶形成基质进行分段加热。
请结合图3-图4、图9-图12进行理解，烟具100还包括两个电极连接件12，两个电极连接件12分别与第一电极和第二电极电连接，且分别将第一电极和第二电极延伸到远离基体11的位置。
以下以与第一电极电连接的电极连接件12为例进行说明：
电极连接件12包括接触部和延伸部124。接触部的至少一部分朝向所述基体11的外表面凸出以与第一藕接电极1132接触以形成电连接；延伸部124相对接触部朝向远离基体11的位置延伸，延伸部124用于耦接电源。
接触部包括本体121、自本体121的表面凸出的二个接触弧122、以及与本体121连接的二个夹紧臂123。延伸部124自本体121朝向远 离基体11的位置延伸。
本体121与基体11的端部的形状相匹配，具体地，本体121形成为弧状。弧状的本体121通过抵接在基体11的端部面进行限位，用于限制接触部与基体11的相对位置进而使接触弧122定位在第一藕接电极1132位置。
二个接触弧122沿基体11轴向方向间隔设置在本体121上。在其他示例中，接触弧122的数量也不作限定，可以为1个或3个以上，可以理解的是，多个接触弧122对于可靠的电连接电极有帮助，但是会增加加工成本，本领域技术人员可以根据需要进行选择。
二个夹紧臂123被配置为与基体11的内表面接触时可产生压紧力，以使得接触弧122与第一藕接电极1132保持接触形成电连接。需要说明的是，夹紧臂123的数量也不作限定。
烟具100还包括套接在远端B上的基座13，基座13选用绝缘的、耐高温隔热的材质。
具体地，基座13包括内筒134和外筒135，基体11可拆卸地套设于所述内筒134的外围。内筒134呈中空管状，气流通过内筒134流向基体11的腔室。内筒134的轴向方向的长度略大于第一非涂层区域1121的轴向方向的长度，以避免气溶胶形成制品(例如烟支)插入时与电极连接件12接触。内筒134的端部具有多个周向分布的凹口，以便于气流通过该凹口流向气溶胶形成制品。外筒135的外壁上具有周向分布的多个径向延伸的凸台，外筒135的端部具有径向延伸的抵接部，凸台和抵接部的设置，便于与隔热管17装配时，使得隔热管17可抵接在抵接部上、同时使得隔热管17的内壁与外筒135的外壁具有一定的间隙以便于冷空气流入。
在基座13上设置有用于阻止基体11转动的周向止动部，周向止动部包括在基座13朝向基体11一侧凸设的定位凸起133，基体11的管壁开设有与定位凸起133对应配合的定位凹口。当基体11套设于内筒134的外围时，定位凸起133与定位凹口对应卡扣配合，以使得阻止基体11相对于基座13周向转动。
在基座13上还设置有用于引出电极连接件12的延伸部124的过孔131。外筒135的内表面还具有多个间隔分布的保持部132，保持部132自外筒135的内表面朝向内筒134方向延伸，保持部132抵接在基体11的外表面以保持基体11的端部。
进一步地，加热器还包括密封件14，密封件14设置在基座13与基体11之间，以对基座13与基体11之间的间隙进行密封。密封件14选 用绝缘的、耐高温隔热的弹性材质，例如：硅胶材质。
进一步地，烟具100还包括套接在基体11的近端A上的基座15以及密封件16，基座15以及密封件16的材质可参考前述部分。
需要说明的是，基座15可以不具有用于引出电极连接件12的延伸部124的过孔131，即基座15与基座13的结构可以不同。
图13是本申请实施方式提供的另一种电极连接件12，与图11不同的是，电极连接件12包括接触部和延伸部124。接触部包括本体121、镂空形成在本体121上的四个悬臂125，四个悬臂125沿基体11周向方向间隔分布，悬臂125的数量也不作限定。四个悬臂125与第一藕接电极1132抵接时能够产生弹性力，实现与第一藕接电极1132的电连接；延伸部124自本体121朝向远离基体11的位置延伸。需要说明的是，图11和图13所示的电极连接件12可以混合使用。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施例，但是，本申请可以通过许多不同的形式来实现，并不限于本说明书所描述的实施例，这些实施例不作为对本申请内容的额外限制，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。并且，上述各技术特征继续相互组合，形成未在上面列举的各种实施例，均视为本申请说明书记载的范围；进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
