本申请要求在2022年7月4日提交至中国国家知识产权局、申请号为202210781228.3、名称为“用于电子烟的雾化芯、用于电子烟的烟弹和电子烟”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子烟技术领域，尤其是涉及一种用于电子烟的雾化芯、用于电子烟的烟弹和电子烟。
背景技术
电子烟通常包括烟弹和烟杆，烟弹安装于烟杆且能够产生被人体吸食的烟雾。烟弹设置有储油腔、气道、雾化腔和雾化芯，储油腔内设置有用于产生烟雾的雾化液，雾化液通过雾化芯加热雾化形成烟雾进入雾化腔，然后通过气道被用户吸入。
相关技术中，用户在抽吸电子烟时，经常会出现“炸油”，或“糊芯”等现象，严重影响烟雾口感。
发明内容
本申请旨在至少解决现有技术中存在的技术问题之一。为此，本申请的一个目的在于提出一种用于电子烟的雾化芯，将该雾化芯装配于电子烟中，用户在抽吸时，雾化液能够充分被雾化，降低了电子烟“炸油”的现象，也能够避免用户在抽吸过程中出现“糊芯”的现象，烟雾口感更纯正。
本申请还提出一种具有上述用于电子烟的雾化芯的用于电子烟的烟弹。
本申请还提出一种具有上述用于电子烟的烟弹的电子烟。
为了实现上述目的，根据本申请的第一方面实施例提出一种用于电子烟的雾化芯，包括：导液体，所述导液体具有相对设置第一侧表面和第二侧表面，所述第一侧表面的至少一部分形成吸液区，所述第二侧表面的至少一部分形成雾化区，所述导液体包括储液部，所述储液部为所述导液体的从所述第二侧表面至所述第二侧表面向所述第一侧表面平移0.5mm～1.5mm处之间的部分，所述储液部的储液量为Q1，定义所述雾化芯在一个抽吸周期中雾化的雾化液的质量为单口雾化量T1,其中，T1≤Q1≤3T1；加热体，所述加热体设置在所述第二侧表面的雾化区。
本申请的发明人在研究过程中发现，相关技术的电子烟在抽吸过程中，之所以会出现“炸油”或糊芯的现象，是因为电子烟的储液仓中的雾化液进入雾化芯后，部分雾化液不能够被充分雾化，而在雾化芯的非雾化区聚集，雾化芯的非雾化区也会被发热体加热，但不足以使烟油雾化，导致出现“炸油”，用户在抽吸过程中，这部分雾化液会随着烟雾一起被吸入用户口中，严重影响烟雾口感；相关技术中，还有出现传导至雾化区的雾化液不够导致出现“糊芯”的现象，也会严重影响烟雾口感。
本申请的发明人进一步研究发现发现，从导液体的靠近雾化区的一侧表面至朝向所述吸液区的一侧表面平移0.5mm～1.5mm处之间的部分的温度能够达到雾化液的雾化温度，即能达到雾化液的有效雾化温度，定义导液体的该部分为储液部，其他部分为导液部，通过对导液部的导液量进行控制，使得储液部的储液量与一个抽吸周期中雾化芯雾化的雾化液的量之间满足一定的关系时，既能保证雾化液被充分雾化，雾化量稳定，又能防止“糊芯”等问题。本申请的发明人通过研究发现，当该储液部的储液量Q1与雾化芯在一个抽吸周期中雾化的雾化液即单口雾化量T1之间满足：T1≤Q1≤3T1时能够有效解决现有技术电子烟抽吸过程中出现的“炸油”或“糊芯”等问题而严重影响电子烟抽吸口感。

在本申请的描述中，“多个”的含义是两个或多于两个。
下面参考附图描述根据本申请实施例的用于电子烟的烟弹100。
如图1-图15所示，烟弹100包括壳体4和根据本申请下述实施例的用于电子烟的雾化芯200。
壳体4内设有储液腔41、气道43以及与气道43连通的雾化腔42。壳体4设有与雾化腔42连通的进气口44以及与气道43连通的出气口45。雾化芯200设于壳体4内。
首先参考附图描述根据本申请实施例的用于电子烟的雾化芯200。
如图1-图15所示，根据本申请实施例的用于电子烟的雾化芯200包括导液体1和加热体2。
导液体1具有相对设置的第一侧表面11和第二侧表面12。这里可以理解地是，第一侧表面11和第二侧表面12相对设置，并非限定为第一侧表面11和第二侧表面12必须平行。第一侧表面11的至少一部分形成吸液区，第二侧表面12的至少一部分形成雾化区。导液体1包括储液部14，储液部14为导液体1的从第二侧表面12至第二侧表面12向第一侧表面11平移0.5mm～1.5mm处之间的部分。
需要说明的是，储液部14的分界面(如图4、图5和图7中的虚线所示)，该分界面与第二侧表面12之间的距离为0.5mm～1.5mm，第二侧表面12至该分界面之间的部分被定义为储液部14。该分界线与第二侧表面12随形设置，即如果第二侧表面12为曲面，则该分界面为曲面(如图4和图5所示)；如果第二侧表面12为平面，则该分界面为平面(如图7所示)。当然，第二侧表面12和该分界面也可以设置为其它形状的面。也就是说，无论第二侧表面12为什么形状，储液部14均为第二侧表面12向第一侧表面11的方向平移0.5mm～1.5mm所限定出的体积。
此外，第一侧表面11也可以设置成不同形状的面，如图4所示的平面，或如图5所示的曲面。
储液部14的储液量为Q1，定义雾化芯200在一个抽吸周期中雾化的雾化液的质量为单口雾化量T1,其中，T1≤Q1≤3T1，进一步地，1.2T1≤Q1≤2.3T1，例如，Q1/T1为1、1.5、2、2.5、3。加热体2设置在第二侧表面12的雾化区。
需要说明的是，单口雾化量T1为一个抽吸周期中雾化液被消耗的质量。并且，储液部14可以为导液体1的 从第二侧表面12至第二侧表面12向第一侧表面11平移0.5mm、0.6mm、0.7mm、0.8mm、0.9mm、1.0mm、1.1mm、1.2mm、1.3mm、1.4mm、或者1.5mm处之间的部分。
举例说明单口雾化量测试方法：单口雾化量通常是依据GB41700-2022进行测量，其中，“单口”所规定的抽吸持续时间为(3.0±0.1)s，抽吸总流量为(55±0.6)ml，用玻璃纤维滤片收集电子烟释放物，在感量≤0.1mg的分析天平上分别称取抽吸前后玻璃纤维滤片的重量，质量差值即为单口雾化量，单位为mg。
其中，第一侧表面11的吸液区与储液腔41连通，吸液区可以从储液腔41吸收雾化液，以便于电子烟中雾化液的雾化。第二侧表面12的雾化区与雾化腔42连通。
根据本申请实施例的用于电子烟的雾化芯200，通过将加热体2设置在第二侧表面12的雾化区，也就是说，吸液区吸收的雾化液在渗透至雾化区的表面后，经加热体2加热形成烟雾(包括但不限于气溶胶、悬浮液体、低温蒸气及挥发性气体)并进入雾化腔42中，用户在抽吸电子烟时，外界空气进入雾化腔42并与雾化腔42中的空气混合，被用户吸食。
根据本申请实施例的用于电子烟的雾化芯200，申请人发现相关技术中所出现的“炸油”、“糊芯”等现象，其原因为每次抽吸过程中雾化芯消耗的雾化液的质量(即单口雾化量)与雾化芯能充分雾化的雾化液的质量不匹配。
基于此，申请人首先想到计算出单口雾化量。申请人在大量实验和研究中发现，用户每次抽吸一次电子烟的平均时间为3秒，用户每次抽吸电子烟需要消耗的平均雾化液量大约为5ml～10ml。
并且在上述基础上，申请人经过深入研究，发现导液体1的从第二侧表面12至第二侧表面12(设置雾化区的表面)向第一侧表面11平移0.5mm～1.5mm处之间的部分的温度大于180℃，该部分的温度为有效雾化温度，即该部分储存的雾化液能够被充分雾化。导液体1的该部分被定义为储液部14。
进一步地，申请人对储液部14的储液量和“炸油”现象之间的关系进行了进一步地研究，申请人发现储液部14的储液量为单口雾化量的1倍～3倍时，不仅能够使储液部14的雾化液被充分雾化，而且储液部14中雾化的雾化液与单口雾化量能够形成匹配，以有效解决现有技术电子烟抽吸过程中出现的“炸油”或“糊芯”等问题而严重影响电子烟抽吸口感。
如此，雾化芯200内储存的油量，与单次抽吸时所消耗的雾化液的质量，不仅能够保证雾化液充足以保证出雾量，而且能够避免雾化液过多而不能被充分雾化，防止未被雾化的雾化液渗透至雾化区以外的部分聚集而出现“炸油”、“糊芯”等现象，保证吸食需求的同时，又防止了漏油，提高了用户体验。
因此，根据本申请实施例的用于电子烟的雾化芯200能够匹配单口雾化量，从而既能保证出雾量，又能保证雾化液被充分雾化。
根据本申请实施例的用于电子烟的烟弹200，通过利用根据本申请上述实施例的用于电子烟的雾化芯100，能够匹配单口雾化量，从而既能保证出雾量，又能保证雾化液被充分雾化。
根据本申请的一些具体实施例，如图4-图8所示，储液部14的储液量为5mg～30mg，储液部14的储液量Q1的计算方式为：储液部14的体积×储液部14的孔隙率×雾化液的密度，其中雾化液的密度为电子烟领域常规使用的烟油的密度，通常为1.05kg/m3～1.2kg/m3。例如，储液部14的储液量可以为6ml～28ml、8ml～25ml、10ml～23ml、12ml～21ml、14ml～19ml、15ml～17ml，例如5ml、10ml、15ml、20ml、25ml或者30ml。
如本申请的其中一个实施例，如图8所示，储液部14的体积的计算方式为：第二侧表面12的面积×储液部14的高度，其中储液部14的高度是指储液部14的从第二侧表面12至第一侧表面11的延伸方向的尺寸，在该实施例中，第二侧表面12的面积＝第二侧表面12的长×第二侧表面12的宽。
在该实施例中，导液部13与储液部14均为多孔陶瓷体，且导液部13与储液部14具有相同的孔隙率，多孔陶瓷体的孔隙率的测量方法为本领域的常规测量方法，例如多孔陶瓷体的孔隙率的测量方法可以依据GBT1966-1996中多孔陶瓷显气孔率试验方法。
这样，能够使储液部14的雾化液被充分雾化，从而能够与单口雾化量形成匹配，以有效解决现有技术电子 烟抽吸过程中出现的“炸油”或“糊芯”等问题而严重影响电子烟抽吸口感。
根据本申请的一些具体实施例，如图4-图8所示，雾化芯200在一个抽吸周期中，抽吸时间为2.9s～3.1s，抽吸总流量为54.4ml～55.6ml，其中，抽吸总流量为空气流量和烟雾流量之和。这样，有利于保证每次抽吸时烟雾的浓度以及烟雾的总量，有利于保证口感，提高用户抽吸体验。
并且，单口雾化量T1＝5mg～10mg。换言之，每次抽吸过程中，雾化液被消耗5mg～10mg，单口雾化量与用户所需的雾化量更为适配，能够满足用户的抽吸需求，也不会雾化量过多而导致雾化液的浪费。
根据本申请的一些具体实施例，如图4-图8所示，导液体1还包括导液部13，导液部13为导液体1的从第一侧表面11至第二侧表面12向第一侧表面11平移0.5mm～1.5mm处之间的部分。导液部的导液量D1满足：0.5T1≤D1≤1.2T1。
也就是说，导液部13的导液量为单口雾化量的0.5倍～1.2倍。更进一步地，导液部的导液量D1满足：0.8T1≤D1≤1.0T1。例如，导液部13的导液量为单口雾化量的0.5倍、0.6倍、0.7倍、0.8倍、0.9倍、0.10倍、1.1倍或1.2倍。
导液部13能够延长导液体1的吸收和渗透雾化液的路径，增加用于雾化的雾化液量。导液部13可以为导液体1的从第一侧表面11至第二侧表面12向第一侧表面11平移0.5mm、0.6mm、0.7mm、0.8mm、0.9mm、1.0mm、1.1mm、1.2mm、1.3mm、1.4mm、或者1.5mm处之间的部分。
其中，用户每次抽吸后，导液部13内的雾化液会补充至储液部14，通过将导液部13的导液量为单口雾化量的0.5倍～1.2倍，导液部13内的雾化液既能够及时补充到储液部14内，为下次用户的抽吸做好准备，又能够避免导液部13向储液部14内补充过多的雾化液。
举例而言，导液部13的导液量计算方式为：导液部13的导液速度×吸液区的面积×一个抽吸周期中的抽吸时间(例如3s)×雾化液的密度，其中雾化液的电子烟领域常规使用的烟油，烟油密度通常为1.05kg/m3～1.2kg/m3。
根据本申请的实施例，如图8所示，吸液区的面积＝第一侧表面11的面积＝第一侧表面11的长×宽。
举例说明导液部13的导液速度的测试方法：将高度为h的干燥的待测导液部13固定于夹具上保持水平，保证导液部13每一条母线都竖直向上，在导液部13上方的中心位置处迅速滴入2至3滴烟油，记录烟油从刚接触导液部13上方区域到刚好渗透至导液部13的下方的时间t，t/h即为所测导液体的导液速度，单位为mm/s。
这样，导液部13的导液量能够满足对储液部14的储液量的补充需求，通过控制导液部13的导液量能够使储液部14的储液量与单口雾化量相匹配，既能保证雾化液被充分雾化，雾化量稳定，又能保证导液部13中的烟油可以及时适量地补充至储液部14，即能够有效解决现有技术电子烟抽吸过程中出现的“炸油”或“糊芯”等问题而严重影响电子烟抽吸口感。
根据本申请的一些具体实施例，如图4-图8所示，导液体1还包括导液部13，导液部13为导液体1的从第一侧表面11至第二侧表面12向第一侧表面11平移0.5mm～1.5mm处之间的部分。导液部13的导液量为2.5ml～12ml，例如，导液部13的导液量为2.5ml、3ml、3.5ml、4ml、4.5ml、5ml、5.5ml、6ml、6.5ml、7ml、7.5ml、8ml、8.5ml、9ml、9.5ml、10ml、10.5ml、11ml、11.5ml或者12ml。
导液部13能够延长导液体1的吸收和渗透雾化液的路径，增加用于雾化的雾化液量。导液部13可以为导液体1的从第一侧表面11至第二侧表面12向第一侧表面11平移0.5mm、0.6mm、0.7mm、0.8mm、0.9mm、1.0mm、1.1mm、1.2mm、1.3mm、1.4mm、或者1.5mm处之间的部分。
举例而言，导液部13的导液量计算方式为：导液部13的导液速度×吸液区的面积×一个抽吸周期中的抽吸时间(例如3s)×雾化液的密度，其中雾化液的密度为1.05kg/m3～1.2kg/m3。
这样，导液部13的导液量能够满足对储液部14的储液量的补充需求，通过控制导液部13的导液量能够使储液部14的储液量与单口雾化量相匹配，既能保证雾化液被充分雾化，雾化量稳定，又能保证导液部13中的烟油可以及时适量地补充至储液部14，即能够有效解决现有技术电子烟抽吸过程中出现的“炸油”或“糊芯”等问题而 严重影响电子烟抽吸口感。
根据本申请的一些具体实施例，如图4-图8所示，导液体1还包括导液部13，导液部13为导液体1的从第一侧表面11至第二侧表面12向第一侧表面11平移0.5mm～1.5mm处之间的部分。导液部13的储液量Q2满足：Q2/Q1＝0.5～2.5。
举例而言，导液部13的储液量Q2的计算方式为：导液部13的体积×导液部13的孔隙率×雾化液的密度，其中雾化液为电子烟领域常规使用侧烟油，如烟油的密度一般为1.05kg/m3～1.2kg/m3。
根据本申请的其中一个实施例，如图8所示，导液部13的体积的计算方式为：第一侧表面11的面积×导液部13的高度，其中导液部13的高度是指导液部13的从第一侧表面11至第二侧表面12的延伸方向的尺寸，在该实施例中，第一侧表面11的面积＝第一侧表面11的长×第一侧表面11的宽。
在该实施例中，导液部13与储液部14均为多孔陶瓷体，且导液部13与储液部14具有相同的孔隙率，多孔陶瓷体的孔隙率的测量方法为本领域的常规测量方法，例如多孔陶瓷体的孔隙率的测量方法可以依据GBT1966-1996中多孔陶瓷显气孔率试验方法。
这样，导液部13的导液量能够满足对储液部14的储液的补充需求，通过控制导液部13的导液量能够使储液部14的储液量与单口雾化量相匹配，既能保证雾化液被充分雾化，雾化量稳定，又能保证导液部13中的烟油可以及时适量地补充至储液部14，即能够有效解决现有技术电子烟抽吸过程中出现的“炸油”或“糊芯”等问题而严重影响电子烟抽吸口感。
并且，导液部13的导液量为D1，D1≤Q2≤3D1。这样，导液部13的导液量和储液量的比值，能够满足对储液部14的储液的补充需求，通过控制导液部13的导液量和储液量的比值，能够使储液部14的储液量与单口雾化量相匹配，既能保证雾化液被充分雾化，雾化量稳定，又能保证导液部13中的烟油可以及时适量地补充至储液部14，即能够有效解决现有技术电子烟抽吸过程中出现的“炸油”或“糊芯”等问题而严重影响电子烟抽吸口感。
根据本申请的一些具体实施例，如图4-图8所示，导液体1还包括导液部13，导液部13为导液体1的从第一侧表面11至第二侧表面12向第一侧表面11平移0.5mm～1.5mm处之间的部分。导液部13和储液部14为分体件或一体件。
通过将导液体1分设为导液部13和储液部14，因此导液部13和储液部14可以一体成型，以降低加工难度。或者导液部13和储液部14分体设置，导液部13和储液部14的构造更为多样，提高了导液体1的适用性，且兼顾成本和雾化效率。
导液部13能够延长导液体1的吸收和渗透雾化液的路径，增加用于雾化的雾化液量。导液部13可以为导液体1的从第一侧表面11至第二侧表面12向第一侧表面11平移0.5mm、0.6mm、0.7mm、0.8mm、0.9mm、1.0mm、1.1mm、1.2mm、1.3mm、1.4mm、或者1.5mm处之间的部分。
根据本申请的一些具体实施例，如图4-图8所示，导液体1还包括导液部13。导液部13为导液体1的从第一侧表面11至第二侧表面12向第一侧表面11平移0.5mm～1.5mm处之间的部分。导液部13和储液部14的材质相同或不同。
导液部13能够延长导液体1的吸收和渗透雾化液的路径，增加用于雾化的雾化液量，导液部13可以为导液体1的从第一侧表面11至第二侧表面12向第一侧表面11平移0.5mm、0.6mm、0.7mm、0.8mm、0.9mm、1.0mm、1.1mm、1.2mm、1.3mm、1.4mm、或者1.5mm处之间的部分。
通过将导液体1分设为导液部13和储液部14，因此导液部13和储液部14可以由不同材料制成，可以采用吸液能力高的材料制成导液部13，而采用耐高温的材料制成储液部14。
或者导液部13和储液部14为相同材料制成，但是导液部13和储液部14的横截面积、容积、高度或者形状等参数不同，从而提高导液体1的适用性，且兼顾成本和雾化效率。
具体地，为了保证储液部14的结构强度和耐高温性能，可以将储液部14设置为陶瓷，例如储液部14由一 个或多个多孔陶瓷件构成；为了提高导液部13吸收和渗透雾化液的效率，导液部13可以为陶瓷，例如导液部13由一个或多个多孔陶瓷件构成。其中，导液部13和储液部14可以是一体成型的整个多孔陶瓷体。
或者，导液部13和储液部14可以为吸油棉，例如储液部14由一个或多个吸油棉构成，导液部13由一个或多个吸油棉构成，导液部13和储液部14可以一体成型，这样成本较低，且安装空间小。
再或者，导液部13和储液部14中的一个为陶瓷且另一个为吸油棉，吸油棉可以粘结到陶瓷上，例如导液部13由一个或多个多孔陶瓷件和一个或多个吸油棉共同构成，导液部14由一个或多个多孔陶瓷件和一个或多个吸油棉共同构成。这样，兼顾了成本、安装空间和吸收以及渗透雾化液的效率。
在本申请的一些实施例中，加热体2为印刷于第二侧表面12的雾化区的加热线路，这样加热体2为印刷成型，与导液体1形成为一体结构，加热体2与导液体1之间连接强度高，且能够同步拆装，生产效率高，且加热体2与导液体1之间更为贴合，对第二侧表面12的雾化液雾化的可靠性更高。
在本申请的另一些实施例中，加热体2为设置于第二侧表面13的雾化区的加热金属网。这样，加热体2与导液体1可以分体设置，便于对加热体2或导液体1进行更换，能够提高回收利用率，以减少损坏。
根据本申请的一些具体实施例，如图6和图8所示，导液体1还包括导液部13，导液部13为导液体1的从第一侧表面11至第二侧表面12向第一侧表面11平移0.5mm～1.5mm处之间的部分。在垂直于从第一侧表面11至第二侧表面12的方向的平面内，导液部13的正投影面积小于或等于储液部14的正投影面积。
通过将导液体1分设为导液部13和储液部14，因此导液部13和储液部14可以由不同材料制成，可以采用吸液能力高的材料制成导液部13，而采用耐高温的材料制成储液部14。
导液部13能够延长导液体1的吸收和渗透雾化液的路径，增加用于雾化的雾化液量。导液部13可以为导液体1的从第一侧表面11至第二侧表面12向第一侧表面11平移0.5mm、0.6mm、0.7mm、0.8mm、0.9mm、1.0mm、1.1mm、1.2mm、1.3mm、1.4mm、或者1.5mm处之间的部分。
由于在垂直于从第一侧表面11至第二侧表面12的方向的平面内，导液部13的正投影面积小于储液部14的正投影面积，因此使得导液部13与储液部14之间可以形成位于导液部13周向的台阶面15，既可以提高导液部13的吸液效率，又可以保证储液部14上加热体2对雾化液进行雾化的效果和稳定性。
根据本申请的一些具体实施例，如图6所示，储液部14构造成长方体形，导液部13构造成长方体形、梯形台形或三角形台形。具体地，导液部13的设置更为多样，能够适用于不同的使用场景，其中，导液部13的与储液部14连接的一面为平面，便于储液部14和导液部13连接。
根据本申请的一些具体实施例，如图6和图8所示，吸液区的面积小于或等于雾化区的面积。也就是说，吸液区吸收的雾化液可以充分渗透至雾化区的至少部分表面，避免了吸液区吸收的雾化液渗透过快而在雾化区以外的低温区域聚集，导致“炸油”，提高了吸液区吸收雾化液的利用效率，保证了雾化腔42中烟雾的雾化纯度，提高了用户的抽吸体验。
具体的，吸液区的面积为雾化区的面积的9％～95％，例如，吸液区的面积可以为雾化区的面积的9％、20％、30％、40％或者50％，以保证吸液区吸收的雾化液的利用效率。而考虑到雾化区的雾化量要求，可以将吸液区的面积设置为接近雾化区的面积，比如吸液区的面积可以为雾化区的面积的60％、70％、80％、90％或者95％。
根据本申请的一些具体实施例，如图4-图8所示，第一侧表面11构造成平面、折线形曲面、弧形曲面或者球形面。其中，第一侧表面11为平面时，第一侧表面11的形状更为规则，便于加工制造。第一侧表面11为折线形曲面、弧形曲面或者球形面时，可以增大储液部14上吸液区的吸液面积，提高吸液效率。
并且，第二侧表面12构造成平面、折线形曲面、弧形曲面或者球形面。其中，第二侧表面12为平面时，第二侧表面12的形状更为规则，便于加工制造。第二侧表面12为折线形曲面、弧形曲面或者球形面时，可以增大储液部14上雾化区的发热面积，提高雾化效率，使得雾化区上雾化液的雾化体积量可以达到第二侧表面12上雾化液体积的95％～98％，有效避免雾化冷凝液的产生。
如图4-图5给出了第二侧表面12的二维弧形曲面的示意图。
根据本申请的一些具体实施例，如图10-图15所示，用于电子烟的雾化芯200还包括雾化芯密封件3，雾化芯密封件3套设于导液体1，雾化芯密封件3设有通液口31，第一侧表面11的至少一部分从通液口31露出以形成吸液区。
这样，一方面通过雾化芯密封件3可以填充导液体1和雾化芯固定件5之间的间隙，从而避免储液腔41内的雾化液不经过导液体1而直接通过导液体1和雾化芯固定件5之间的间隙泄漏到雾化腔42内，保证了雾化液的雾化率，进而保证了雾化液的利用率。另一方面，通液口31的设置，能够使储液腔41内的雾化液与导液体1接触，以便于雾化液通过通液口31流到吸液区。
根据本申请的一些具体实施例，如图1-图3所示，壳体4具有长度方向(箭头A所指方向)、宽度方向(箭头B所指方向)和厚度方向(箭头C所指方向)。壳体4沿长度方向的最大尺寸大于壳体4沿宽度方向的最大尺寸，壳体4沿宽度方向的最大尺寸大于或等于壳体4沿厚度方向的最大尺寸，第一侧表面11和第二侧表面12沿壳体4的长度方向布置。
也就是说，壳体4沿厚度方向的最大尺寸最小，使得壳体4呈扁平状，便于用户放入嘴中抽吸。而壳体4沿长度方向的最大尺寸最大，由于第一侧表面11和第二侧表面12沿壳体4的长度方向布置，因此储液腔41和雾化腔42在壳体4的长度方向布置在导液体1的相对两侧，即储液腔41、导液体1和雾化腔42三者沿壳体4的长度方向布置，从而充分利用壳体4内的空间，提高了壳体4的空间利用率。
根据本申请的一些具体实施例，如图1-图3所示，用于电子烟的烟弹100还包括雾化芯固定件5。
雾化芯固定件5设于壳体4内，雾化芯固定件5分隔储液腔41和雾化腔42。雾化芯固定件5上具有安装槽51，雾化芯200设置在安装槽51处，雾化芯固定件5上设置有连通通道52。安装槽51和连通通道52沿壳体4的宽度方向布置，连通通道52的一端与气道43对接，连通通道52的另一端连通至雾化腔42。
在安装槽51和连通通道52沿壳体4的宽度方向布置时，可以避免安装槽51和连通通道52一同在壳体4的厚度方向上占据较大的尺寸，保证了壳体4的薄型化设置，增强了壳体4的流线型设计效果，便于用户放入嘴中抽吸。并且，连通通道52的两端分别与气道43和雾化腔42连通，雾化腔42内的烟雾经连通通道52、气道43和出气口45可以被用户吸入，以实现用户的使用需求。
根据本申请的一些具体实施例，如图1-图3所示，进气口44包括外进气段441和内进气段442，外进气段441和内进气段442均沿着壳体4的长度方向延伸，内进气段442与雾化腔42连通，外进气段441与外界连通。沿着壳体4的宽度方向，内进气段442相对于外进气段441向远离连通通道52的方向偏移预定距离。
具体地，从进气口44进入的气流与雾化腔42的雾化气混合后，然后通过连通通道52、气道43和出气口45被用户抽吸。也就是说，外部气流会先流经外进气段441，然后流经内进气段442，再通过雾化腔42流向连通通道52。内进气段442相对于外进气段441向远离连通通道52的方向偏移预定距离时，相当于形成了外进气段441、内进气段442和连通通道52的曲线型气流路径，增加了气流路径的长度，一方面可以调整气流的速率，另一方面可以增强外部气流和雾化气流的混合效果。
预定距离的具体大小可以根据外部气流的流量、雾化气流的雾化量以及外部气流和雾化气流的混合要求来调整。
根据本申请的一些具体实施例，如图1-图13所示，雾化芯200还包括雾化芯密封件3，雾化芯密封件3套设于导液体1，雾化芯密封件3具有沿着壳体4的长度方向延伸的遮挡部32，遮挡部32延伸至雾化腔42中，遮挡部32设置在雾化腔42与连通通道52的连通处，以限制该连通处的气流。
具体地，雾化腔42中的雾化气体可以在外部气流的带动下流向连通通道52，而遮挡部32延伸至雾化腔42中，并且遮挡部32设置在雾化腔42与连通通道52的连通处时,会阻挡至少部分从雾化腔42中流向连通通道52的气流，也就限制了连通处的气流的流动速率，可以实现对气流速率的灵活调整。
根据本申请的一些具体实施例，如图1-图3所示，用于电子烟的烟弹100还包括上密封件6，上密封件6具有包封部61和塞部62。沿壳体4的宽度方向和/或厚度方向，连通通道52的端部具有开口521。包封部61套设于雾化芯固定件5，包封部61与雾化芯固定件5以及壳体4的内壁形成挤压配合关系。塞部62封堵在该开口521，塞部62与该开口521以及壳体4的内壁形成挤压配合关系。
具体地，包封部61与雾化芯固定件5以及壳体4的内壁形成挤压配合关系时，也就是包封部61夹设于雾化芯固定件5和壳体4的内壁之间，提高了雾化芯固定件5分隔储液腔41和雾化腔42的效果，避免了储液腔41中的雾化液从雾化芯固定件5和壳体4的内壁之间泄漏到雾化腔42中。
而连通通道52端部的开口521可以便于雾化芯固定件5的成型，但连通通道52中的雾化气流也存在从开口521泄漏到壳体4内的风险。而塞部62封堵在该开口521，并且塞部62与该开口521以及壳体4的内壁形成挤压配合关系时，也就是塞部62封堵于雾化芯固定件5和壳体4的内壁之间，避免了连通通道52中的雾化气流从雾化芯固定件5的开口521泄漏到壳体4中。
另外，上密封件6还包括第一密封圈63。第一密封圈63密封连通通道52和气道43之间的连接处，以保证烟弹100中气流通道的密封性。
根据本申请的一些具体实施例，如图1-图3所示，上密封件6与雾化芯固定件5之间设有换气通道7，换气通道7被配置为能将雾化腔42与储液腔41连通。
具体地，雾化腔42与储液腔41之间的压差小于设定压力时，由于雾化腔42通过进气口44与外部连通，也就是雾化腔42中的压力接近或者等于大气压力，储液腔41中的气压保持在可以顺畅下液的状态，此时换气通道7处于封闭状态，同时可以避免储液腔41中的液体通过换气通道7进入雾化腔42。而雾化腔42与储液腔41之间的压差大于或者等于设定压力时，雾化腔42与储液腔41之间的压差会打通换气通道7，实现雾化腔42与储液腔41之间的气压平衡。
根据本申请的一些具体实施例，如图1-图3所示，雾化芯固定件5上设置有与安装槽51间隔开的换气沉槽53，换气沉槽53的侧壁上形成有贯通的穿孔531，穿孔531连通至雾化腔42。雾化芯固定件5的外周面上形成有连通槽54，连通槽54的一端与穿孔531连通，连通槽54的另一端连通至储液腔41。上密封件6盖住穿孔531和连通槽54，上密封件6、穿孔531与连通槽54构成换气通道7。当雾化腔42的压力大于储液腔41的压力时，上密封件6在压力差的作用下变形以打开换气通道7。
其中，当雾化腔42的压力大于储液腔41的压力时，具体为雾化腔42与储液腔41之间的压差大于或者等于设定压力时，在雾化腔42与储液腔41的压力差作用下以打开换气通道7。具体为，雾化腔42与储液腔41的压力差会使得上密封件6发生变形，进而上密封件6可以解除对穿孔531和连通槽54的封堵，通过雾化腔42对储液腔41中的气流补充，以使储液腔41内的待雾化介质能够顺利地流向加热体2。
当雾化腔42的压力不大于或者稍大于储液腔41的压力时，也就是雾化腔42与储液腔41之间的压差小于设定压力时，此时储液腔41与雾化腔42两者之间的压力平衡，换气通道7关闭，使得待雾化介质能够顺利地流向加热体2。
由此，通过换气通道7可以有效地调节储液腔41与雾化腔42之间的压力差，使得储液腔41的压力能够大于雾化腔42的压力，保证待雾化介质能够顺利地流向加热体2并进行有效雾化。
根据本申请的一些具体实施例，如图1-图3所示，壳体4包括主壳体46和下盖47，出气口45形成在主壳体46的一端，主壳体46的另一端敞开且被下盖47封盖，进气口44形成于下盖47。
具体地，下盖47扣合在主壳体46的敞开处时，可以在壳体4内形成容纳空间，而雾化芯固定件5将该容纳空间分隔为储液腔41和雾化腔42。出气口45和进气口44分别设置在主壳体46和下盖47相互远离的一侧，从进气口44进入的气流与雾化腔42的雾化气混合，然后通过出气口45被用户抽吸，可以在壳体4内形成长距离的气流路径，保证雾化液的充分雾化，提高用户的抽吸效果。
另外，烟弹100还包括第二密封圈92，第二密封圈92夹设于下盖47和主壳体46敞开处的内壁之间，以保证壳体4内部的密封性。
根据本申请的一些具体实施例，如图1-图3所示，下盖47包括底板471和从底板471朝向雾化腔42延伸的侧板472，底板471的内表面上盖设有吸液件9，吸液件9围绕进气口44布置，或者侧板472上支撑有吸液件9。
待雾化液等雾化介质在雾化腔42雾化后，如果加热体2停止工作，雾化腔42中的雾化气会重新冷凝，吸液件9能够吸附冷凝的待雾化介质。这样能够防止冷凝的待雾化介质从进气口44泄漏，提高烟弹100使用的清洁性，也避免与烟弹100连接的结构(例如电子烟的烟杆)被冷凝的待雾化介质腐蚀以及堵塞。
根据本申请的一些具体实施例，如图1-图3所示，下盖47上穿设有导电钉10，导电钉10的一端与加热体2抵顶，导电钉10的另一端从下盖47的外表面上露出。其中，导电钉10的另一端与电子烟的烟杆中的储能件电连接，从而用户抽吸电子烟时，储能件通过导电钉10向加热体2供电，以使加热体2加热雾化液，使雾化液雾化为气溶胶而被用户吸入。
根据本申请的一些具体实施例，如图1-图3所示，用于电子烟的烟弹100还包括阻油透气件8，阻油透气件8封盖进气口44。阻油透气件8封盖进气口44时，可以在保证进气口44的外部气流顺利进入雾化腔42的情况下，避免雾化腔42中冷凝的雾化液从进气口44流出。
根据本申请的一些具体实施例，如图1-图3所示，用于电子烟的烟弹100还包括导气金属板，导气金属板覆盖进气口44。其中，阻油透气件8可以为薄膜状结构，阻油透气件8安装于导气金属板的背向进气口44的一侧，导气金属板用于固定阻油透气件8的形状。
下面参考附图描述根据本申请实施例的电子烟，电子烟包括根据本申请上述实施例的烟弹100和烟杆(未示出)。烟杆内设置有电气组件(未示出)，电气组件与加热体2形成电连接，电气组件被配置为向加热体2供电。
具体地，烟杆装置内设置有电气组件，烟杆装置具有顶端敞开的容纳槽。烟弹100包括雾化芯200，至少一部分壳体4插接于容纳槽内，雾化芯200与电气组件形成电连接。雾化芯200中的加热体2具体可以通过导电钉10与电气组件形成电连接。电气组件可以通过导电钉10给雾化芯200的加热体2供电，实现加热体2中电能和热能的转化。
在用户使用电子烟时，用户通过出气口45抽吸。外部空气经进气口44进入雾化腔42。电子烟内的传感器感测到用户抽吸的动作，电气组件与加热体2之间的电连接导通并向加热体2供电，以加热雾化储液腔41中的液体形成烟雾，空气进入雾化腔42带动烟雾经由气道43和出气口45被用户吸入，以保证用户的抽吸体验。
根据本申请实施例的电子烟，通过利用根据本申请上述实施例的烟弹100，能够匹配单口雾化量，从而既能保证出雾量，又能保证雾化液被充分雾化。
根据本申请实施例的用于电子烟的雾化芯200、用于电子烟的烟弹100和电子烟的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
