Description

加热部件 技术领域
本发明涉及一种低温烟具用的加热部件。
 背景技术
传统的卷烟通过点燃使烟草高温燃烧产生气体分散体系来实现发烟，其中雾烟占比成分很大，而且包含多种有害物质，为了减害，推出了需要借助器械使用的新型烟草制品——低温烟（也称加热不燃烧烟）。与传统的卷烟需要点燃的抽吸方式相比，低温烟具加热烟支的抽吸装置加热烟草或烟碱制品时，加热温度在220-250℃间，通过对烟草的烘烤使烟气逐渐挥发出来，并不对烟草进行直接燃烧发烟，可以减少通过传统卷烟中烟草的燃烧和热降解产生有害烟气成分。
加热部件是低温烟具加热烘烤烟支的一种核心部件，其中管式加热部件最为常见，烟支或者烟弹插入管状结构的加热部件中，然后加热部件产生的热量从外向内对烟支或烟弹内的烟草进行烘烤加热。传统的低温烟具的加热部件多为多层复合结构的加热管，如申请号为201820507322.9的中国专利公开的烘烤型电子烟的加热装置，在金属基体材料上叠加加热材料、外层保护材料或电极层等，结构和制作工艺都较为复杂，制作成本高昂，并且加热管同时对插入的烟支进行整体加热，烟支的部分烟草加热时间过长会导致有害烟气的产生，在低温烟具抽吸过程中需要外部空气进入烟支内部成流动的气流将烟气带出，现有的低温烟具大多还需要单独设计烟道进入到加热部件内部，烟道在烟具内部结构复杂并且容易出现堵塞导致出烟不连续。

 有益效果
本发明的加热部件通过温控带分成两部加热部，每个加热部实现独立加热，通过加热部件本身作为导体进行通电加热，不需要在加热部件的表面印制分区加热的加热电路，加工工艺更加简单。通过对各个加热部上的电极通电连接即可实现对加热部件内部腔体的发烟介质的分区加热，在整个发烟介质的加热流程中，可以通过分区加热或者一区加热、另一区预热的方式提高发烟介质的发烟效率和出演连续性，避免单一区域连续加热导致有害物质的产生。

本发明的加热部件上集成设置气道，气道一可以将加热部件的第一加热部和第二加热部之间实现整体结构连接，二作为低温烟具抽吸过程中的进气通道，气流通过气道流动进入加热部件底部，随着使用者的抽吸作用，将加热部件内部的发烟介质加热产生的烟气带出，减少了烟具内部的气道结构设置，并且气道位于加热部件外壁，不容易发生堵塞，出烟更加连续顺畅。

 本发明的最佳实施方式
在此处键入本发明的最佳实施方式描述段落。
 本发明的实施方式
实施例一。
参见图1，图示中的加热管1为本发明的具体实施方案，该加热管1为两端开口的管体结构，其中一端用于向管体内腔插入发烟介质，包括但不限于烟支或者烟弹，加热管1的管体本身可做成对插入的发烟介质进行烘烤加热的导体电阻，加热管1的管体在通电的状态下能够升温发热，从而将插入的发烟介质进行加热，使其释放形成气体分散体系。本实施例中的该管体被两条温控带13分割成可以独立发热的第一加热部11和第二加热部12，通过第一加热部11和第二加热部12对发烟介质的不同区域进行分区加热。其中两条温控带13之间位于同一个倾斜平面内，该倾斜平面分别相对管体的轴向平面和横向截面与管体倾斜相交，在加热管的管体管壁形成两条并不连续的相贯线，两条温控带13就与该两条相贯线重合。
本实施例将第一加热部11和第二加热部12设置为具有相同表面积的发热区域，即第一加热部11和第二加热部12对插入加热管内的发烟介质分别加热一半，为了保证第一加热部11和第二加热部12具有相同的发热表面积，将温控带13所在的斜平面穿过加热管1的管体几何中心，即可保证将加热管1的管体分割成两个相同大小并且以管体几何中心呈点对称的两部分加热部。
加热管1的圆柱管体在平面上的正视投影为图2中所示的矩形，并且在该正视视角下，温控带13所在的斜平面与投影平面垂直，温控带13呈一条斜线将代表加热管1的矩形斜切，为了保证能够在加热管1的前后形成两条不连续的相贯线，温控带13所在斜面的倾斜角度应该大于代表加热管1的矩形的对角线倾斜角度，使得温控带13所在的斜面不会全部相贯于加热管1的管壁上。如图1所示，第一加热部11和第二加热部12之间通过温控带13所在的倾斜平面分割，第一加热部11的上部分区域朝向第二加热部12的所在位置延伸，第二加热部12的下部分区域朝向第一加热部11的所在位置延伸，在二者之间形成半交错的方式，这样一来，在加热粗支烟时，第一加热部11在加热粗支烟的左半部分（图中所示方位）时，能够同时对右半部分上部区域进行预热；第二加热部12在加热右半部分时，能够使得左半部分下部区域保持一定的温度，使得烟支能够顺畅的产生烟雾供使用者抽吸。
在本实施例中，温控带13设置为将加热管1的管体切断的缝隙，温控带13将加热管1的管体分割成两个独立的部分，即第一加热部11和第二加热部12。为了保持加热管1的整体管状形态，本实施例在每条温控带13上设有两个连接块14，连接块14分别与第一加热部11和第二加热部12固定连接，保持加热管1的管体结构。本实施例在加工过程中，可以直接先加工成一个完整的管体，然后通过切割设备沿设定的温控带斜面将该管体斜切成第一加热部11和第二加热部12，然后将连接块14通过胶粘、热熔或者钎焊的方式再将第一加热部11和第二加热部12连接成加热管的管状整体，连接块14可以为绝缘的块状结构或者直接采用公用电极参与到第一加热部11和第二加热部12中的发热电路连接中。
本实施例中的连接块14仅仅为连接结构，并且保持第一加热部11和第二加热部12之间为绝缘状态。结合参见图1和图2，本实施例在加热管1的第一加热部11外壁上设有第一电极111和第二电极112，第一电极111和第二电极112分别连接在低温烟具的同一加热电路上，对第一加热部11所覆盖的发热区域进行加热，第二加热部12上设有第三电极121和第四电极122，第三电极121和第四电极122分别连接在低温烟具的同一加热电路上，对第二加热部12所覆盖的发热区域进行加热。第一加热部11和第二加热部12之间可以同时加热，也可以通过分区依次加热或者其中一个加热部加热，另一加热部预热的方式进行加热控制，具体的加热控制方式可以参考现有低温烟具的加热控制电路，本实施例在此不做赘述。
管状的加热管1被温控带13所在的斜平面从上下两端斜切后，将加热管1的管体分成单独通电发热的两个加热部，在每一加热部上均设置电极，使得每一加热部均可形成电流的通路，第一电极111和第二电极112的两个接口之间形成一个加热回路，使得第一加热部11形成通电回路，使第一加热部11在通电时升温，第三电极121和第四电极122的两个接口之间形成一个加热回路，使得第二加热部12形成加热回路，使第二加热部12在通电时升温。为了保证各个加热部上的电流平均流过各自加热部的导体，第一加热部11上的电极和第二加热部12上的电极沿各自加热部的中心轴向分布，结合图3、图4和图5所示，即第一电极111和第二电极112之间沿加热管的管体轴向布置在第一加热部11外壁的中线上，第三电极121和第四电极122之间沿加热管的管体轴向布置在第二加热部12外壁的中线上，这样在各个加热部上的电流均沿加热部导体的中间区域流通。
同时，为了保证电流在各个加热部上的均匀分布，所有的电极均采用沿加热管周向的条状电极，并且各个电极的长度与所在加热部的周向长度匹配。
具体如图3中的加热管展开示意图来看，第一加热部11展开后类似倒梯形，上部宽下部窄，也就是在管体状态下第一加热部11上部的周向长度要长于下部的周向长度，第一电极111位于第一加热部11的上部，第二电极112位于第一加热部11的下部，那么第一电极111的长度要长于第二电极112的长度；同理，第二加热部12展开后类似正梯形，上部窄下部宽，说明在管体状态下第二加热部12上部的周向长度要短于下部的周向长度，第三电极121位于第二加热部12 的上部，第四电极122位于第二加热部12的下部，那么第三电极121的长度要短于第四电极122的长度，这样电极适应各自加热部所在周向长度，增大流通电流对加热部周向的覆盖范围，提高加热部的加热效率。
另外，为了使得各加热部获得需要的温度，实现对发烟介质的精确加热，在第一加热部11和第二加热部12上分别设置能够采集温度信息的第一温度传感器113和第二温度传感器123，第一温度传感器113和第二温度传感器123分别与对应加热部的加热控制模块反馈连接，从相应的温度传感器上获取相应加热部的温度信息，从而控制通向该加热部的加热电流，最终精确控制该加热部的温度。
为了更加精确地检测加热部的温度，应当将温度传感器设置在各自加热部的中心发热位置，具体如图3、图4和图5所示，第一温度传感器113位于第一加热部11的第一电极111和第二电极112之间，并且第一电极111、第一温度传感器113和第二电极112之间沿第一加热部11的中心轴向分布；第二温度传感器123位于第二加热部12的第三电极121和第四电极122之间，并且第三电极121、第二温度传感器123和第四电极122之间沿第二加热部12的中心轴向分布。
结合参见图2和图3，本实施例中的加热管1的管体展开成平面后，两条温控带13在展开铺平后的两段曲线与正弦函数曲线x=ksint或余弦函数曲线x=kcost中的两个对称段重合后的效果最佳，如图6中所示的正弦曲线中的两根实线段，从图6中所示的正弦曲线可以发现，温控带13的倾斜度（如图1和图2中所示，温控带13所在斜平面与管体的轴向平面或横向截面呈一定夹角的倾斜状）对应图6中正弦函数的振幅，故温控带13的位置可由其对应的函数的振幅来限定。温控带13的长度对应图6中正弦函数的周期，故温控带13的长度可由其对应的正弦函数的周期限定。另外，加热管1的长度决定了温控带13所对应的正弦函数曲线的振幅的上限，加热管1的直径决定了温控带13所对应的正弦函数曲线的周期的上限。加热管1的横截面的周长对应余弦函数曲线的周期。
在本实施例中，温控带所处正弦函数曲线的振幅a的取值范围为10mm-80mm，此范围能够充分的保证不同的加热管均落入该范围，使得其能够对发烟介质进行分区式的加热，同时还能够在加热一个区域时对另一个区域预热或/和保温，使得发烟介质能够快速的、连续不断的得以释放。温控带13所处正弦函数或余弦函数曲线的周期t的取值范围为9.42mm-31.4mm，该范围使得不同体积的介质都能够很好的被加热管所容纳，增大了加热管的适用性。
实施例二。
参见图7，图示中的加热部件为本发明的一种具体实施方案，用于低温烟具，对发烟介质进行加热以产生可以抽吸的气溶胶，图示中的加热部件的主体为加热管1，该加热管1为两端开口的管体结构，其中一端用于向管体内腔插入发烟介质，包括但不限于烟支或者烟弹，加热管1的管体本身可做成对插入的发烟介质进行烘烤加热的半导体，其内部均匀混合多晶材料，加热管1的管体在通电的状态下能够升温发热，从而将插入的发烟介质进行加热，使其释放形成气体分散体系。本实施例中的该管体被两条温控带13分割成可以独立发热的第一加热部11和第二加热部12，通过第一加热部11和第二加热部12对发烟介质的不同区域进行分区加热。其中两条温控带13之间位于同一个倾斜平面内，该倾斜平面分别相对管体的轴向平面和横向截面与管体倾斜相交，在加热管的管体管壁形成两条并不连续的相贯线，两条温控带13就与该两条相贯线重合。加热管1的管体外壁固定设有气道2，气道2其中一端与加热管1的管体内腔连通，便于外部气流在抽吸压力的作用下进入加热管1内腔带走发烟烟气。
本实施例将第一加热部11和第二加热部12设置为具有相同表面积的发热区域，即第一加热部11和第二加热部12对插入加热管内的发烟介质分别加热一半，为了保证第一加热部11和第二加热部12具有相同的发热表面积，将温控带13所在的斜平面穿过加热管11的管体几何中心，即可保证将加热管11的管体分割成两个相同大小并且以管体几何中心呈点对称的两部分加热部。
加热管1的圆柱管体在平面上的正视投影为图8中所示的矩形，并且在该正视视角下，温控带13所在的斜平面与投影平面垂直，温控带13呈一条斜线将代表加热管1的矩形斜切，为了保证能够在加热管1的前后形成两条不连续的相贯线，温控带13所在斜面与管体横向截面之间的倾斜角度应该大于代表加热管1的矩形的对角线倾斜角度，使得温控带13所在的斜面不会全部相贯于加热管1的管壁上。
在本实施例中，温控带13设置为将加热管1的管体切断的缝隙，温控带13将加热管1的管体分割成两个独立的部分，即第一加热部11和第二加热部12。为了保持加热管1的整体管状形态，加热管1的管体外壁设置的气道将将第一加热部11和第二加热部12之间固定连接。本实施例在加热管1的管体外壁固定设置有两条气道2，两条气道2之间沿管体的轴线布置，并且在管体圆周上间隔180°设置。两条气道2分别与两条温控带13分别相交，这样气道2的外壁与加热管1的管体外壁固定连接，气道2作为一个轴向连接结构将第一加热部11和第二加热部12之间连接成管状整体，气道2不被温控带13的缝隙切断，内部保留连续的气流通道。气道2可以与加热管1的管体一体成型加工，也可以直接加工一个完整的管体，然后通过切割设备沿设定的温控带斜面将该管体斜切成第一加热部11和第二加热部12，然后将单独的气道部件通过胶粘、热熔或者钎焊的方式与第一加热部11和第二加热部12固定连接，将第一加热部11和第二加热部12连接成加热管的管状整体。
结合图7和图11，本实施例中的气道2的底部与加热管1的底部连通，在加热管1的底部扣装有底盖3，底盖3上设有同时与加热管1底部和气道2底部扣合的定位边31，在底盖3与加热管1底部扣合的定位边31上对应气道2的圆周位置上设有进气口32，进气口32将气道2的底端和加热管1的底端实现相互连通。气道2内部的气流沿其通道从上向下流动至气道底部和底盖3之间后，通过进气口32进入到加热管1内部，然后通过作用在加热管1顶部的抽吸压力将发烟烟气沿加热管内部向上带出。
结合参见图7、图8和图9，本实施例在加热管1的第一加热部11外壁上设有第一电极111和第二电极112，第一电极111和第二电极112分别连接在低温烟具的同一加热电路上，对第一加热部11所覆盖的发热区域进行加热，第二加热部12上设有第三电极121和第四电极122，第三电极121和第四电极122分别连接在低温烟具的同一加热电路上，对第二加热部12所覆盖的发热区域进行加热。第一加热部11和第二加热部12之间可以同时加热，也可以通过分区依次加热或者其中一个加热部加热，另一加热部预热的方式进行加热控制，具体的加热控制方式可以参考现有低温烟具的加热控制电路，本实施例在此不做赘述。
管状的加热管1被温控带13所在的斜平面从上下两端斜切后，将加热管1的管体分成单独通电发热的两个加热部，在每一加热部上均设置电极，使得每一加热部均可形成电流的通路，第一电极111和第二电极112的两个接口之间形成一个加热回路，使得第一加热部11形成通电回路，使第一加热部11在通电时升温，第三电极121和第四电极122的两个接口之间形成一个加热回路，使得第二加热部12形成加热回路，使第二加热部12在通电时升温。为了保证各个加热部上的电流平均流过各自加热部，第一加热部11上的电极和第二加热部12上的电极沿各自加热部的中心轴向分布，结合图7、图8和图9所示，即第一电极111和第二电极112之间沿加热管的管体轴向布置在第一加热部11外壁的中线上，第三电极121和第四电极122之间沿加热管的管体轴向布置在第二加热部12外壁的中线上，这样在各个加热部上的电流均沿加热部的中间区域流通。
同时，为了保证电流在各个加热部上的均匀分布，所有的电极均采用沿加热管周向的条状电极，并且各个电极的长度与所在加热部的周向长度匹配。
具体如图9中的加热管展开示意图来看，第一加热部11展开后类似倒梯形，为上宽下窄，也就是在管体状态下第一加热部11上部的周向长度要长于下部的周向长度，第一电极111位于第一加热部11的上部，第二电极112位于第一加热部11的下部，那么第一电极111的长度要长于第二电极112的长度；同理，第二加热部12展开后类似正梯形，为上窄下宽，说明在管体状态下第二加热部12上部的周向长度要短于下部的周向长度，第三电极121位于第二加热部12 的上部，第四电极122位于第二加热部12的下部，那么第三电极121的长度要短于第四电极122的长度，这样电极适应各自加热部所在周向长度，增大流通电流对加热部周向的覆盖范围，提高加热部的加热效率。
另外，为了使得各加热部获得需要的温度，实现对发烟介质的精确加热，在第一加热部11和第二加热部12上分别设置能够采集温度信息的第一温度传感器113和第二温度传感器123，第一温度传感器113和第二温度传感器123分别与对应加热部的加热控制模块反馈连接，从相应的温度传感器上获取相应加热部的温度信息，从而控制通向该加热部的加热电流，最终精确控制该加热部的温度。
为了更加精确地检测加热部的温度，本实施例将温度传感器设置在各自加热部的中心发热位置，即温度传感器位于其所在的第一加热部或第二加热部的相对中心区域，该相对中心区域，指的是将加热器进行平面展开后的靠近平面中心的位置。具体如图7、图8和图9所示，第一温度传感器113位于第一加热部11的第一电极111和第二电极112之间，并且第一电极111、第一温度传感器113和第二电极112之间沿第一加热部11的中心轴向分布；第二温度传感器123位于第二加热部12的第三电极121和第四电极122之间，并且第三电极121、第二温度传感器123和第四电极122之间沿第二加热部12的中心轴向分布。
结合参见图8和图9，本实施例中的加热管1的管体展开成平面后，两条温控带13在展开铺平后的两段曲线与正弦函数曲线y=Asin(ωx+φ)+k或余弦函数曲线y=Acos(ωx+φ)+k 中的两个对称段重合后，分区效果最为明显，生产制作时也更便于操作，成本更低且实现分段加热发烟介质的效果最佳，如图10中所示的正弦曲线中的两根实线段，从图10中所示的正弦曲线可以发现，温控带13的倾斜度（如图7和图8中所示，温控带13所在斜平面与管体的轴向平面或横向截面呈一定夹角的倾斜状）对应图10中正弦函数的振幅，故温控带13的位置可由其对应的函数的振幅来限定。温控带13的长度对应图10中正弦函数的周期，故温控带13的长度可由其对应的正弦函数的周期限定。另外，加热管1的长度决定了温控带13所对应的正弦函数曲线的振幅的上限，加热管1的直径决定了温控带13所对应的正弦函数曲线的周期的上限。加热管1的横截面的周长对应余弦函数曲线的周期。
在本实施例中，温控带13所处正弦函数曲线的振幅a的取值范围为10mm-80mm，此范围能够充分的保证不同的加热管均落入该范围，使得其能够对发烟介质进行分区式的加热，同时还能够在加热一个区域时对另一个区域预热或/和保温，使得发烟介质能够快速的、连续不断的得以释放。温控带13所处正弦函数或余弦函数曲线的周期t的取值范围为9.42mm-31.4mm，该范围使得不同体积的介质都能够很好的被加热管所容纳，增大了加热管的适用性。
