为了改善雾化芯的温度分布，目前往往是增加雾化芯面积，特别是增大雾化芯的雾化面面积，以改善雾化效果，提升烟雾量，但是这样就会使得电子烟的结构尺寸较大，不便于用户携带和手持。现有电子烟中雾化芯的宽度尺寸一般为5mm，甚至雾化芯的宽度更宽，这种情况下，电子烟壳体结构也会相应地增大。因此，现有技术中电子烟结构是与电子烟小型化的发展趋势相悖的。
基于此，申请人经过长期的创造性劳动，得出以下发明创造。
根据本申请实施例第一方面，提供了一种电子烟雾化芯。参照图1-图8所示，电子烟雾化芯包括：
多孔体10和条形发热体40。
多孔体10具有吸液端和雾化端，所述雾化端具有远离所述吸液端的第一端面，所述条形发热体40设置在所述第一端面上。
所述第一端面具有沿第一方向延伸并沿第二方向间隔设置的第一边缘11和第二边缘12，所述第一边缘11和所述第二边缘12在第二方向上的间距为第一尺寸h1。
所述第一端面具有沿第二方向延伸并沿第一方向间隔设置的第三边缘13和第四边缘14，所述第三边缘13和所述第四边缘14在第一方向上的间距为第二尺寸h2。
所述第二尺寸h2/第一尺寸h1的比值范围≥2，且所述第一尺寸h1的范围为：1.2mm-3.8mm。
换句话说，根据本申请实施例的电子烟的雾化芯主要由能够起到承载作用的多孔体10，以及通电后能够产生热量的条形发热体40组成。
参照图1-图8所示，多孔体10具有吸液端和雾化端，电子烟内部的烟油会通过所述吸液端渗向所述雾化端；所述雾化端具有远离所述吸液端的第一端面，条形发热体40设置于所述雾化端的第一端面上。在本实施例中第一端面为多孔体10的雾化面101。
第一端面具有沿第一方向延伸的第一边缘11和第二边缘12，且第一边缘11和第二边缘12在第二方向上间隔开分布。例如，如图1和图2所示，可以将第一方向定义为左右方向，并将第二方向定义为上下方向。当然，第一方向也不限于左右方向，第二方向也不限于上下方向，在此不作限定。第一边缘11和第二边缘12分别沿着左右方向延伸，且在上下方向上间隔开分布。在第一边缘11和第二边缘12之间的区域可以作为承载安装区域，例如在安装区域上设置条形发热体40。需要说明的是，多孔体10可以为陶瓷多孔陶瓷基体或其他多孔陶瓷基体，在此不作限定。
第一边缘11和第二边缘12在第二方向上的间距为第一尺寸h1，其中第一尺寸h1范围为第一边缘11和第二边缘12之间的最大距离范围。例如第一边缘11和第二边缘12可以为直线型边缘或者为样条曲线型边缘。
第一端面具有沿第二方向延伸的第三边缘13和第四边缘14，且第三 边缘13和第四边缘14在第一方向上间隔开分布。例如，如图1和图2所示，可以将第一方向定义为左右方向，并将第二方向定义为上下方向。当然，第一方向也不限于左右方向，第二方向也不限于上下方向，在此不作限定。第三边缘13和第四边缘14分别沿着上下方向延伸，且在左右方向上间隔开分布。在第三边缘13和第四边缘14之间的区域可以作为承载安装区域，例如在安装区域上设置有条形发热体40。
第三边缘13和第四边缘14在第一方向上的间距为第二尺寸h2，其中第二尺寸h2范围为第三边缘13和第四边缘14之间的最大距离范围。例如第三边缘13和第四边缘14可以为直线型边缘或者为样条曲线型边缘。
本申请实施例中第二尺寸h2与第一尺寸h1的比值范围(即第二尺寸h1/第一尺寸h1)≥2，且第一尺寸h1的范围为：1.2mm-3.8mm。具体地，第二尺寸h2/第一尺寸h1的比值大于或者等于2，并限定第一尺寸h1范围为1.2mm-3.8mm，使得雾化芯在第二方向上的宽度尺寸更窄。例如第一尺寸h1为第一端面的宽度尺寸，第二尺寸h2为第一端面的长度尺寸。另外雾化芯的工艺水平(例如雾化芯的孔隙和孔径等参数)、雾化芯的导油速度、以及雾化芯的导热系数(较小优化)影响着第一端面的雾化效果。在不影响雾化芯的整体雾化效果的前提下，本申请实施例将雾化芯在第二方向上的宽度尺寸(即第一尺寸h1)设计的更窄，适合用于小型的电子烟中。例如第一尺寸h1为2mm、2.8mm或者3.8mm。
在一个实施例中，参照图1-图8所示，所述第二尺寸h2的范围为：6.5mm-15mm。
具体地，本实施例对第一端面在第一方向上的第二尺寸h2进行了限定。即对第一端面在第一方向上的长度尺寸进行了限定。第一端面在第一方向上的长度尺寸与第一端面在第二方向上的宽度尺寸乘积为第一端面的面积。条形发热体40设置在第一端面上，将第一端面的面积限定在此范围内，在满足了对条形发热体40的长度设置需求的情况下，本实施例的雾化芯的结构更加小巧。
在一个实施例中，参照图1所示，所述第一端面为雾化面101，所述吸液端具有远离所述雾化端的第三端面，所述第三端面为吸液面102。
在该实施例中，例如多孔体为椭圆体结构。第一端面为雾化面101，第三端面为吸液面，电子烟内部的烟油会通过所述吸液面渗向所述雾化面101，雾化面101用于对烟油进行雾化。
在一个实施例中，所述雾化端上设置有凸块，所述凸块具有远离所述吸液端的第二端面及位于所述凸块外周的侧面，所述第二端面为所述雾化面101，或者所述第二端面和所述侧面为所述雾化面101，所述吸液端具有远离所述雾化端的第三端面，所述第三端面为所述吸液面102。
在该实施例中，所述条形发热体40设置于第二端面，也就是条形发热体40设置于所述凸块远离所述吸液端的一侧。或者条形发热体40设置于第二端面和侧面，以使得第二端面和侧面均形成雾化面101。由此，可以充分利用凸块的端面和侧面，避免在凸块的端面设置过大的雾化面101面积，从而在充分利用所述凸块形成的雾化面101时，可以在提高条形发热体40的发热速率基础上，可以保证所述雾化面101的有效雾化面积101，提高所述发热体的发热效率和所述电子烟雾化芯的雾化量。
在一个实施例中，所述吸液面102具有沿第二方向延伸并在第一方向上间隔设置的第七边缘17和第八边缘18，所述第七边缘17和所述第八边缘18沿第一方向的最大距离为第三尺寸h3，所述第三尺寸h3大于所述第二尺寸h2。
在一个实施例中，所述吸液面102具有沿第一方向延伸并在第二方向上间隔设置的第五边缘15和第六边缘16，所述第五边缘15和所述第六边缘16在第二方向上的最大距离为第四尺寸h4，所述第四尺寸h4与所述第一尺寸h1相同。
具体地，吸液面102具有沿第二方向延伸并在第一方向上间隔设置的第七边缘17和第八边缘18，第七边缘17和所述第八边缘18沿第一方向的最大距离为第三尺寸h3，其中第七边缘17和第八边缘18可以为直线型边缘或者为样条曲线型边缘。本实施第七边缘17和第八边缘18在第一方向上的第三尺寸h3大于第三边缘13和第四边缘14在第一方向上的第二尺寸h2；即吸液面102在第一方向上的长度尺寸大于雾化面101在第一方向上的长度尺寸。
吸液面102具有沿第一方向延伸并在第二方向上间隔设置的第五边缘15和第六边缘16，第五边缘15和第六边缘16在第二方向上的最大距离为第四尺寸h4。本实施例中第五边缘15和第六边缘16在第二方向上的第四尺寸h4与第一边缘11和第二边缘12在第二方向上的第一尺寸h1相同。即吸液面102在第二方向的宽度尺寸与雾化面101在第二方向上的宽度尺寸一致。本实施例通过限定吸液面102在第二方向的宽度尺寸，进一步限定了雾化芯在第二方向上的整体宽度尺寸范围为：1.2mm-3.8mm，相比于现有技术，本实施例雾化芯在第二方向上的宽度更窄。
本实施例吸液面102在第一方向的长度大于雾化面101在第一方向的长度，即吸液面102的面积大于雾化面101内的面积，吸液面102能够从电子烟的储液腔中吸取较多的烟油，较多的烟油被雾化面101雾化，能够提高电子烟的整体雾化量。
在一个实施例中，参照图1-图8所示，所述第三尺寸h3范围为：7.5mm-22mm。例如第三尺寸h3可以为8mm、9mm、15mm、20mm。
具体地，本实施例对吸液面102在第一方向上的第三尺寸h3进行了限定。即对吸液面102在第一方向上的长度尺寸进行了限定。也即对雾化芯在第一方向上的长度尺寸进行了限定。吸液面102在第一方向上的长度尺寸与吸液面102在第二方向上的宽度尺寸乘积为吸液面102的面积。吸液面102对电子烟中储液腔中的烟油吸附，吸液面102的面积在此范围内，在避免了雾化芯吸附过多烟油容易出现漏液现象的情况下，同时又满足了电子烟对雾化量的需求。
在一个实施例中，参照图1-图8所示，所述雾化面101为长方形、椭圆形或者跑道形。
在本申请的另一实施例中，所述吸液面102为也为长方形、椭圆形或跑道形。
具体地，参照图1和图2以及图7和图8所示，雾化面101为长方形，吸液面102为椭圆形结构。其中长方形的长边对应雾化面101的第二尺寸h2；长方形的短边对应雾化面101的第一尺寸h1；椭圆形的长轴对应吸液面102的第三尺寸h3；椭圆形的短轴对应吸液面102的第四尺寸h4。
参照图3-图6所示，雾化面101为长方形，吸液面102为长方形。其中长方形的长边对应雾化面101的第二尺寸h2；长方形的短边对应雾化面101的第一尺寸h1；长方形的长边对应吸液面102的第三尺寸h3，长方形的短边对应吸液面102的第四尺寸h4。
需要说明的是：本实施例对雾化面101和吸液面102的结构不作特别限定，雾化面101和吸液面102只需要满足长扁形结构即可。
现有技术在雾化芯上设置条形发热体，条形发热体用于加热经由雾化芯传导的烟油而生成气溶胶。为了改善雾化芯的温度分布，让温度分布更加均匀，目前往往是增加雾化芯面积，特别是增大雾化芯的雾化面101面积，以改善雾化效果，提升烟雾量。例如可以将雾化芯面积设计为普通陶瓷芯的2倍，改善雾化芯的温度分布，让温度分布更均匀。但是这完全违背了电子烟小型化的设计理念。
因为为了适应电子烟小型化的发展趋势，雾化芯的结构为较窄型的雾化芯。例如本申请实施例中雾化芯在第二方向上的宽度尺寸范围为：1.2mm-3.8mm。雾化芯的宽度尺寸变窄，在较窄型的雾化芯上设置发热丝的难度较大。因此在较窄型的雾化芯上设置发热丝的线长难以保证，而且容易导致发热丝温度偏高，雾化芯温度分布不均匀。因此如何在较窄的雾化芯上设置发热丝是亟待解决的技术问题。另外如何在较窄的雾化芯上设置的发热丝使得雾化芯的温度分布均匀也是亟待解决的技术问题。
在本申请实施例电子烟的雾化芯上设置有条形发热体40。具体地，在一个实施例中，所述条形发热体在第一端面曲线延伸，所述雾化面101上，所述条形发热体40具有沿第二方向延伸且沿第一方向相邻设置的两个加热段403，两个所述加热段403在第一方向上的尺寸最小间距为第五尺寸h5，所述第五尺寸h5范围为：0.2mm-2mm。第五尺寸h5为0.5mm、1mm、1.5mm。
具体地，条形发热体40设置在雾化面101上，条形发热体40的左端和与正电极对应的第一接线盘20电连接，条形发热体40的右端和与负电极对应的第二接线盘30电连接。其中需要说明的是，也可以将条形发热体40的左端和与负电极对应的第二接线盘30电连接，并将条形发热体40的 右端和与正电极对应的第一接线盘20电连接，在此不作限定。
当正电极和负电极通电时，电流可以从正电极流出，经过包围在正电极周围的第一接线盘20后，流向条形发热体40的左端，然后电流从条形发热体40的左端流向条形发热体40的右端，最后电流经过包围在负电极周围的第二接线盘30后流向负电极，形成完整的通路，从而使得条形发热体40产生热量。
具体地，本实施例中通过限定相邻两个加热段403之间的距离，以改善雾化芯的温度分布情况。例如在雾化面101的长度尺寸一定的情况下，在第一方向上相邻加热段403之间的距离尺寸越小，条形发热体40在第一方向上设置的加热段403数量越多，能够改善雾化芯的温度分布，让温度分布更均匀。但是相邻加热段403在第一方向上的尺寸越小，相邻加热段403产生的热量势必会相互影响，又会造成热量集中点。
例如在加热段403的集中分布区域，相邻加热段403的之间的距离较小，很容易在该区域产生热量集中点，使得条形发热体40产生的热量在多孔体10上分布不均衡，影响条形发热体40和多孔体10的使用寿命。
如果相邻加热段403在第一方向上的距离较大，使得条形发热体40在第一方向上排布比较分散，也会使得条形发热体40产生的热量分布不均匀。
因此限定在第一方向上相邻设置加热段403之间的距离就至关重要。本申请人发现，将相邻加热段403在第一方向上的距离限定在此范围内，使得条形发热体40产生的热量分布更加均匀，提高烟油受热均匀性。
参照图1-图2所示，条形发热体40在第一方向上具有3段沿第二方向延伸的加热段403。在第一方向上彼此相邻的两个加热段403在第一方向上的最小间距范围为：0.2mm-2mm。
参照图3-图4所示，条形发热体40在第一方向上具有4段沿第二方向延伸的加热段403。在第一方向上彼此相邻的两个加热段403在第一方向上的最小间距范围为：0.2mm-2mm。
参照图5-图6所示，条形发热体40在第一方向上具有5段沿第二方向延伸的加热段403。在第一方向上彼此相邻的两个加热段403在第一方 向上的最小间距范围为：0.2mm-2mm。
参照图7-图8所示，条形发热体40在第一方向上具有3段沿第二方向延伸的加热段403。在第一方向上彼此相邻的两个加热段403在第一方向上的最小间距范围为：0.2mm-2mm。
在一个实施例中，参照图1-图8所示，两个所述加热段403通过弯折段404连接，所述弯折段404朝向所述第一边缘11弯折或者所述弯折段404朝向所述第二边缘12弯折。
在一个实施例中，所述弯折段404朝向所述第一边缘11弯折，所述弯折段404与所述第二边缘12在第二方向上的最短距离范围为：0.05mm-2mm。例如最短距离可以为0.1mm、0.5mm、1.5mm。
在一个实施例中，所述弯折段404朝向所述第二边缘12弯折，所述弯折段404与所述第一边缘11在第二方向上的最短距离范围为：0.05mm-2mm。
具体地，在第一方向上相邻设置的加热段403分别具有第一端和第二端，在第一方向上相邻设置的两个加热段403处于同侧的端部通过弯折段404连接。
参照图3-图4所示，条形发热体40从左至右包括第一个加热段、第二个加热段、第三个加热段和第四个加热段。第一个加热段和第二个加热段通过一个弯折段404连接，第二个加热段和第三个加热段通过一个弯折段404连接，第三个加热段和第四个加热段通过一个弯折段404连接。其中两个弯折段404朝向第二边缘12弯折，另外一个弯折段404朝向第一边缘11弯折。
其中朝向第二边缘12弯折的弯折段404与第一边缘11在第二方向上的最短距离范围为0.05mm-2mm。朝向第一边缘11弯折的弯折段404与第二边缘12在第二方向上的最短距离范围为0.05mm-2mm。
通过设置弯折段404能够扩大加热面积，提高烟油受热均匀性。因此本实施例对弯折段404在第二方向上与第二边缘12或弯折段404在第二方向上与第一边缘11的最短距离进行限定，避免雾化芯上靠近第一边缘11、第二边缘12附近的部件的寿命受到影响，还防止用户使用雾化芯时手部被 第一边缘11、第二边缘12附近位置的高温烫伤。
在一个实施例中，参照图3-图8所示，所述条形发热体40具有首端加热段401和末端加热段402，所述首端加热段401和所述末端加热段402中的至少一个沿第一方向延伸；
在一个实施例中，参照图3-图8所示，所述首端加热段401沿第一方向延伸，所述首端加热段401与所述第一边缘11或所述第二边缘12在第二方向上的最短距离范围为：0.05mm-2mm；
在一个实施例中，参照图3-图8所示，所述末端加热段402沿第一方向延伸，所述末端加热段402与所述第一边缘11和所述第二边缘12在第二方向上的尺寸范围为：0.05mm-2mm。
具体地，参照图3-图6所示，首端加热段401的一端与第一接线盘20连接，末端加热段402的一端与第二接线盘30连接。第一接线盘20和第二接线盘30自身产生的热量不多，因此首端加热段401和末端加热段402周围温度较低。在满足条形发热体40长度设置需求的情况下，本实施例对首端加热段401在第二方向上与第一边缘11或第二边缘12的尺寸范围进行限定，以及对末端加热段402在第二方向上与第一边缘11或者第二边缘12的尺寸范围进行限定，避免了首端加热段401和末端加热段402产生的热量影响第一边缘11和第二边缘12的温度。
在一个实施例中，所述首端加热段401和与其连接的加热段通过弧形片段连接，所述弧形片段的曲率半径大于0.2。例如曲率半径可以为0.5、1或者3。
例如参照图1和图2所示，首端加热段401沿第二方向延伸，首端加热段401的一端与第一接线盘20连接，另一端与弯折段404连接。弯折段404上形成有弧形片段。
例如参照图3-图6所示，首端加热段401和沿第二方向延伸的加热段403通过弧形片段连接。沿第二方向延伸的加热段403呈S型结构。
例如参照图7-图8所示，首端加热段401和沿第二方向延伸的加热段403通过弧形片段连接。沿第二方向延伸的加热段403呈S型结构。
本实施例首端加热段401和与其连接的加热段通过弧形片段连接，弧 形片段的曲率半径大于0.2，避免了条形发热体40在相邻连接的两个加热段容易出现断裂的情况。具体地，条形发热体40在加热和冷却过程中，由于条形发热体40与多孔体10膨胀率的不同，每一处都会受到条形发热体40的曲线切线方向的压缩或拉伸，而采用弧形片段使得加热段上每一处的受力不会在一个方向上叠加，从而降低了加热段在大温差情况下断裂的风险。
在一个实施例中，所述条形发热体40总长度范围为：7mm-30mm。在一个具体的实施例中，所述条形发热体40的总长度范围为25mm-30mm。
具体地，本实施例通过改进相邻加热段在第一方向上的尺寸、或通过限定加热段与第一边缘11或者第二边缘12的距离、或通过限定条形发热体40在第一方向上的弯折次数、或通过限定条形发热体40在第二方向上的宽度尺寸，以达到了在较窄型的雾化面101上设置较长的条形发热体40的目的。例如将条形发热体40的长度限定在此范围内，满足了条形发热体40的长度需求，改善了雾化芯的温度分布，让温度分布更均匀。
在一个实施例中，参照图1-图8所示，所述条形发热体40的宽度范围为0.05mm-2.3mm。例如条形发热体40的宽度范围可以为0.1mm、0.5mm、1mm、1.5mm、2mm。
其中将条形发热体40在第二方向上的最大竖直距离定义为所述条形发热体40的宽度，所述条形发热体40的宽度h9范围为：0.05mm-2.3mm。
具体地，条形发热体40在第二方向上的最大竖直距离定义为：条形发热体40曲线延伸设置在雾化面101上，沿雾化面101的第二方向，条形发热体40的最高点至条形发热体40的最低点的竖直距离为条形发热体40的最大竖直距离。
如果条形发热体40的宽度范围过大，条形发热体40产生的热量会影响第一边缘11温度和第二边缘12温度。如果条形发热体40的宽度范围过小，条形发热体40产生的热量较小，使得雾化芯雾化效果较差。
本申请对条形发热体40的宽度尺寸进行限定，使得条形发热体40能够最大程度的均匀分布在雾化面101上，并确保雾化芯雾化均匀，雾化效果一致。
在一个实施例中，所述第一端面的面积与所述条形发热体的面积之比小于6。
具体地，第一尺寸h1与所述第二尺寸h2的乘积定义为第一端面的面积；
所述条形发热体40具有长度尺寸和宽度尺寸，所述条形发热体40的长度尺寸与所述宽度尺寸的乘积定义为所述条形发热体40的面积。
所述第一端面的面积与所述条形发热体40的面积的之比小于6。
具体地，本实施例对第一端面(也即雾化面101)的面积与条形发热体40的面积的比值进行限定，一方面能够满足雾化芯小型化的设计；另一方面能够使得在较窄型的雾化芯上设置较长的条形发热体40，确保雾化芯雾化均匀，雾化效果一致。
在一个实施例中，参照图1-图8所示，所述雾化面101上设置有第一接线盘20和第二接线盘30，所述吸液面102与所述雾化面101相对设置，所述吸液面102至所述雾化面101的延伸方向为第三方向，所述第一接线盘20在第三方向具有第一中心轴，所述第二接线盘30在第三方向具有第二中心轴，所述第一中心轴与所述第二中心轴之间的距离h6为：1.2mm-14mm。例如两轴之间的距离h6为1.5mm、4mm、6mm、10mm、13mm。
具体地，在雾化面101上设置第一接线盘20和第二接线盘30，第一接线盘20和第二接线盘30沿第一方向间隔开分布。如图1和图2所示，第一接线盘20设于正电极周围，并且能够与正电极电连接，第二接线盘30设于负电极周围，并且能够与负电极电连接。条形发热体40设置在雾化面101上，条形发热体40的左端和与正电极对应的第一接线盘20电连接，条形发热体40的右端和与负电极对应的第二接线盘30电连接。
本实施例对两个接线盘之间的间距进行限定，使得雾化面101上形成较多的安装区域用于排布条形发热体40。
第一接线盘20具有第一中心轴，第二接线盘30具有第二中心轴，第一中心轴和第二中心轴之间的距离h6为1.2mm-14mm。本申请实施例将第一中心轴和第二中心轴的尺寸设置在此范围内，在保证相邻加热段之间的 基本间距和条形发热体40与接线盘之间的基本间距前提下，增加了第一接线盘20和第二接线盘30在第一方向上的横向间距，进而增大了条形发热体40在雾化面101上的排布总面积。
例如条形发热体40在第一接线盘20和第二接线盘30之间通过增加弯折次数可以满足对条形发热体40的线长需要。例如条形发热体40在第一接线盘20和第二接线盘30通过弯折多次延长条形发热体40的线长。其中条形发热体40在第一接线盘20和第二接线盘30之间的弯折段404可以是奇数或者偶数。
本实施例增加了第一接线盘20和第二接线盘30在第一方向上的横向间距，进而增大了条形发热体40在雾化面101上的排布总面积。另一方面，条形发热体40均匀分布在第一接线盘20和第二接线盘30之间，确保了条形发热体40在多孔体10上分布的均匀性，确保了多孔体10温度分布的均匀性，进而确保了多孔体10雾化烟液的一致性。
在一个实施例中，参照图1-图8所示，所述第一接线盘20具有靠近所述第三边缘13的第一侧面，所述第一侧面与所述第三边缘13在所述第一方向上的最短距离h8为：0.15mm-1mm。例如最短距离h8可以为0.3mm、0.5mm、0.8mm。
在一个实施例中，所述第二接线盘30具有靠近所述第四边缘14的第二侧面，所述第二侧面与所述第四边缘14在所述第一方向上的最短距离为：0.15mm-1mm。
本实施例通过限定第一接线盘20与第三边缘13的最短距离h8，以及限定第二接线盘30与第四边缘14的最短距离，增大了第一接线盘20和第二接线盘30之间的横向间距。另外将第一接线盘20与第三边缘13的最短距离限定在此范围内，能够避免雾化面101的第三边缘13温度过高的情况。将第二接线盘30与第四边缘14的最短距离限定在此范围内，能够避免雾化面101的第四边缘14温度过高的情况。
在一个实施例中，所述第一接线盘20在第一方向上的尺寸范围为：0.6mm-1mm；或者所述第二接线盘30在第一方向上的尺寸范围为：0.6mm-1mm；或者所述第一接线盘20和所述第二接线盘30在第一方向上 的最大尺寸范围为：0.6mm-1mm。
例如参照图1-图8所示，本实施例对第一接线盘20和第二接线盘30在第一方向上的尺寸范围限定，在不影响接线盘与电极的连接强度的情况下，避免了第一接线盘20和第二接线盘30占用过多的雾化面101的安装区域，进而形成较多的安装区域用于排布条形发热体40。
例如参照图1-图2和图7-图8所示，接线盘的结构可以为环形结构。参照图3-图6所示，接线盘的结构可以为不规则结构。
需要说明的是，本实施例对接线盘的结构不作限定，接线盘的设计不影响条形发热体40的雾化面101上的排布即可。
在一个实施例中，所述条形发热体40具有靠近所述第一接线盘20的第一加热段，其中靠近所述第一接线盘20的第一加热段沿第二方向延伸；
所述第一接线盘20在第一方向上具有靠近条形发热体40的第三侧面；
第一加热段与所述第三侧面的最短距离h7为：0.3mm-1.5mm。
在一个实施例中，所述条形发热体40具有靠近所述第二接线盘30的第二加热段，第二加热段403沿第二方向延伸；所述第二接线盘30在第一方向上具有靠近所述条形发热体40的第四侧面；
第二加热段与所述第四侧面的最短距离为：0.3mm-1.5mm。
具体地，本实施例对接线盘和与其在第一方向上相邻设置的加热段在第一方向上的尺寸进行限定，以满足条形发热体40在雾化面101上的排布线长。另外将接线盘和与其在第一方向上相邻设置的加热段在第一方向上的尺寸限定在此范围内，在不影响条形发热体40在雾化面101上的排布情况下，避免了在接线盘和加热段之间存在加热集中点。
在一个实施例中，参照图1-图2所示，沿吸液面102至雾化面101的延伸方向，所述雾化面101具有第三中心轴；
所述第一中心轴相对于所述第三中心轴向所述多孔体10的第二边缘12偏移第一预定距离；
所述第二中心轴相对于所述第三中心轴向所述多孔体10的第一边缘11偏移第二预定距离。
参照图1和图2所示，第一接线盘20具有第一中心轴，第一中心轴 相对于第三中心轴向多孔体10的第二边缘12偏移第一预定距离。具体地，本申请实施例中第一中心轴向下偏移第一预定距离。第二接线盘30具有第二中心轴，第二中心轴相对于第三中心轴向靠近多孔体10的第一边缘11偏移第一预定距离。具体地，本申请实施例中第二中心轴向上偏移第一预定距离。
第一接线盘20和第二接线盘30自身的发热量远小于条形发热体40的发热量。因此将第一接线盘20和第二接线盘30中心轴偏移第一预定距离，在不影响多孔体10的边缘温度的情况下，增大了条形发热体40在多孔体10的第二方向上的排布区域。
第一接线盘20向靠近多孔体10的第二边缘12偏移设置，第二接线盘30向靠近多孔体10的第一边缘11偏移设置。因此第一接线盘20和第二接线盘30位于多孔体10的不同侧，使得曲线延伸在第一接线盘20和第二接线盘30之间的条形发热体40能够在多孔体10的两侧均匀分布，提高了条形发热体40产生的热量在多孔体10上分布的均衡性，使得条形发热体40的温度分布更加均匀。
在一个实施例中，参照图1和图2所示，所述第一预定距离与所述第一尺寸之比为1/5-1/3；或者，所述第二预定距离与所述第二尺寸之比为1/5-1/3；或者，所述第一预定距离和所述第二预定距离与所述第一尺寸之比均为1/5-1/3。
具体地，如果第一接线盘20的第一中心轴相对于第三中心轴偏移的距离过大，第一接线盘20更靠近第二边缘12设置，条形发热体40产生的热量传导至第一接线盘20，第一接线盘20温度会对第二边缘12温度造成影响，进而影响电子烟壳体温度，影响电子烟的使用寿命。
如果第一接线盘20的第一中心轴相对于第三中心轴偏移的距离过小，在多孔体10的第二方向上不会预留更多的区域去布置条形发热体40，进而会影响条形发热体40在多孔体10上布置的长度。
本实施例中将第一预定距离限定在此范围内，确保了条形发热体40在多孔体10上的布置长度。
需要说明的是，第一预定距离的尺寸与第二预定距离的尺寸可以相同 也可以不相同。特别地，为了使得条形发热体40在多孔体10上分布更加均匀，第一预定距离的尺寸与第二预定距离的尺寸设置为相同。
在一个实施例中，参照图1和图2所示，所述条形发热体40包括首端加热段401，所述首端加热段401的一端与所述第一接线盘20连接；所述首端加热段401由所述第一接线盘20朝向所述多孔体10的第一边缘11延伸；
所述条形发热体40包括末端加热段402，所述末端加热段402的一端与所述第二接线盘30连接，所述末端加热段402由所述第二接线盘30朝向所述多孔体10的第二边缘延伸。
具体地，在第一接线盘20的第一中心轴向靠近多孔体10的第二边缘12偏移第一预定距离的情况下，在第一接线盘20上设置有首端加热段401，首端段加热段401与第一接线盘20电连接。首端加热段401沿多孔体10的第二方向向靠近第一边缘11侧延伸预设距离。在第二接线盘30的第二中心轴向靠近多孔体10的第一边缘11偏移第二预定距离的情况下，在第二接线盘30上设置有末端加热段402，末端加热段402与第二接线盘30电连接。末端加热段402沿多孔体10的第二方向向靠近第二边缘12延伸预设距离。
因此本申请实施例的条形发热体40在与接线盘连接时，条形发热体40能够沿多孔体10的第二方向延伸，确保了设置在多孔体10上条形发热体40的长度。
因此本申请实施例中，将第一接线盘20和第二接线盘30中心位置向不同侧偏移预定距离，在不影响多孔体10的边缘温度的情况下，一方面增大了条形发热体40在多孔体10的第二方向上的排布区域。
在一个实施例中，所述条形发热体40包括沿第二方向延伸并在第一方向相邻设置第一侧加热段、中间加热段和第二侧加热段，其中中间加热段位于第一侧加热段和第二侧加热段之间；
其中第一侧加热段、中间加热段和第二加热段通过弯折方向相反的两个弯折段404连接，两个所述弯折段404在第一方向上向靠近彼此方向倾斜。
例如两个弯折段404呈半弧形结构，弯折段404关于中轴线对称设置，其中中轴线为一条倾斜线。
例如两个弯折段404包括第一弯折段和第二弯折段。
其中第一弯折段的中轴线与第二弯折段的中轴线平行设置。第一弯折段产生的热量与中间加热段产生的热量彼此互相影响，在第一弯折段整体向靠近第二侧加热段倾斜的情况下，第一弯折段和第二侧加热段自身以及其周围分布的热量更加均匀。
例如第二弯折段呈半弧形结构，第二弯折段关于中轴线对称设置，其中中轴线为一条倾斜线。第二弯折段的中轴线与第一弯折段的中轴线平行设置。第二弯折段产生的热量与中间加热段产生的热量彼此互相影响，在第二弯折段整体向靠近第一侧加热段倾斜的情况下，第二弯折段404和第一侧加热段自身以及其周围分布的热量更加均匀。
在一个实施例中，所述中间加热段的宽度大于所述第一侧加热度段宽度或者所述第二侧加热段宽度。
具体地，由于中间加热段外侧被多条加热段包围，因此为了防止中间加热段附近热量过高，可以将中间加热段的宽度加宽，从而减小中间加热段的电阻，最终实现中间加热段的热量降低，从而能够进一步有效避免中间加热段的热量过于集中。
在一个实施例中，所述条形发热体40为中心对称体。通过采用中心对称结构，不仅便于加工生产，还有利于实现条形发热体40发出的热量的均匀性。
根据本申请实施例的第二方面，提供了一种电子烟。电子烟包括上述的电子烟雾化芯。由于根据本申请实施例的电子烟雾化芯具有上述技术效果，因此，根据本申请实施例的电子烟也具有上述技术效果。最终可以使得电子烟的结构更加便于携带和手持。
虽然已经通过例子对本申请的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本申请的范围。本领域的技术人员应该理解，可在不脱离本申请的范围和精神的情况下，对以上实施例进行修改。本申请的范围由所附权利要求 来限定。
