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202221708335.5、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油液，油液通过雾化芯加热雾化形成烟雾进入雾化腔，然后经由雾化腔进入气道被用户吸入。
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：导油体，所述导油体具有相对设置的导油侧表面和储油侧表面，所述导油侧表面的至少一部分形成吸液区，所述储油侧表面的至少一部分形成雾化区，所述导油体包括储油部，所述储油部为所述导油体的从所述储油侧表面至所述储油侧表面向所述导油侧表面平移0.5mm～1.5mm处之间的部分，所述储油部的储液量为5mg～30mg；以及加热体，所述加热体设置在所述储油侧表面的雾化区。
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腔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，实际抽吸时从导油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，定义导油体的该部分为储油部，其他部分为导油部，通过控制储油部的储液量，使其满足储油部的储液量Q1为5mg～30mg，其会与雾化芯在一个抽吸周期中雾化液的雾化量达到平衡，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”的含义是两个或两个以上。
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12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内设有储油腔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12所示，根据本申请实施例的用于电子烟的雾化芯200包括导油体1和加热体2。
导油体1具有相对设置的导油侧表面11和储油侧表面12，导油侧表面11的至少一部分形成吸液区，储油侧表面12的至少一部分形成雾化区。导油体1包括储油部14，储油部14为导油体1的从储油侧表面12至储油侧表面12向导油侧表面11平移0.5mm～1.5mm处之间的部分。
需要说明的是，储油部14的分界面(如图4、图5和图7中的虚线所示)，该分界面与储油侧表面12之间的距离为0.5mm～1.5mm，储油侧表面12至该分界面之间的部分被定义为储油部14。该分界面与储油侧表面12随形设置，即如果储油侧表面12为曲面，则该分界面为曲面(如图4和图5所示)；如果储油侧表面12为平面，则该分界面为平面(如图7所示)。当然，储油侧表面12和该分界面也可以设置为其它形状的面。也就是说，无论储油侧表面12为什么形状，储油部14均为储油侧表面12向导油侧表面11的方向平移0.5mm～1.5mm所限定出的体积。
此外，导油侧表面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。
储油部14的储液量为5mg～30mg，加热体2设置在储油侧表面12的雾化区。
其中，导油侧表面11的吸液区与储油腔41连通，吸液区可以从储油腔41吸收烟油，所吸收的烟油被设于储油侧表面12的加热体2加热雾化。储油侧表面12的雾化区与雾化腔42连通。
举例而言，储油部14的储液量为5mg～30mg。储油部14的储液量的计算方式为：储油部14的体积×储油部14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的烟油。根据本申请的实施例，烟油的密度一般为1.05kg/m3～1.2kg/m3。并且，储油部14的储液量可以为6mg～28mg、8mg～25mg、10mg～23mg、12mg～21mg、14mg～19mg、15mg～17mg，例如5mg、10mg、15mg、20mg、25mg或者30mg。储油部14可以为导油体1的从储油侧表面12至储油侧表面12向导油侧表面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。
根据本申请的一个实施例的雾化芯，导油体1如图8所示，其中储油部14的体积的计算方式为：储油侧表面12的面积×储油部14的高度，其中储油部14的高度是指储油部的从储油侧表面12至导油侧表面11的延伸方向的尺寸，在该实施例中，储油侧表面12的面积＝储油侧表面12的长×储油侧表面12的宽。
在该实施例中，导油部13与储油部14均为多孔陶瓷体，且导油部13与储油部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。
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设置在储油侧表面12的雾化区，也就是说，吸液区吸收的烟油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、低温蒸汽及挥发性气体)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，发明人发现相关技术中所出现的“炸油”、“糊芯”等现象，其原因为用户单次抽吸所需的油液量与雾化芯所有效雾化的油液量不匹配。
基于此，发明人首先想到计算出单口雾化所需的油液量。发明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油液量大约为5mg～10mg。
并且在上述基础上，发明人经过深入研究，发现导油体1的从储油侧表面12至储油侧表面12(设置雾化区的表面)向导油侧表面11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，该部分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，导油体1的该部分被定义为储油部14。
进一步地，发明人对储油部14的储液量和“炸油”现象之间的关系进行了进一步地研究，发明人发现储油部14的储液量为单口雾化所需的油液量的1倍～3倍时，能够形成匹配，因此将储油部14的储液量设置为5mg～30mg。
如此，雾化芯200内储存的油量，与用户单次雾化所需的油液量相匹配，不仅能够保证油液充足以保证出雾量，而且能够避免油液过多而不能被充分雾化，防止未被雾化的油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能够匹配单口雾化所需油液量，从而既能保证出雾量，又能保证油液被充分雾化。
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，能够匹配单口雾化所需油液量，从而既能保证出雾量，又能保证油液被充分雾化。
根据本申请的一些具体实施例，如图4-图8所示，导油体1还包括导油部13，导油部13为导油体1的从导油侧表面11至储油侧表面12向导油侧表面11平移0.5mm～1.5mm处之间的部分；导油部的储液量Q2满足：Q2/Q1＝0.5～2.5，例如，导油部13的储液量为储油部14的储液量的0.5倍、0.6倍、0.7倍、0.8倍、0.9倍、0.10倍、1.1倍、1.2倍、1.3倍、1.4倍、1.5倍、2倍或者2.5倍。
导油部13能够延长导油体1的吸收和渗透烟油的路径，增加用于雾化的烟油量，导油部13可以为导油体1的从导油侧表面11至储油侧表面12向导油侧表面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，导油部13的储液量的计算方式为：导油部13的体积×导油部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的烟油。根据本申请的实施例，烟油的密度一般为1.05kg/m3～1.2kg/m3。
根据本申请的一个实施例的雾化芯，导油体1如图8所示，其中导油部13的体积的计算方式为：导油侧表面11的面积×导油部13的高度，其中导油部13的高度是指导油部的从导油侧表面11至储油侧表面12的延伸方向的尺寸。在该实施例中，导油侧表面11的面积＝导油侧表面11的长×导油侧表面11的宽。
在该实施例中，导油部13与储油部14均为多孔陶瓷体，且导油部13与储油部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，导油部13的导液量能够满足对储油部14的储液量的补充需求，通过控制导油部13的导液量能够使储油部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，又能保证导油部13中的烟油可以及时适量地补充至储油部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，导油部13的导液量为D1，D1≤Q2≤3D1。这样，导油部13的导液量和储液量的比值，能够满足对储油部14的储液的补充需求，通过控制导油部13的导液量和储液量的比值，能够使储油部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，又能保证导油部13中的烟油可以及时适量地补充至储油部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，导油体1还包括导油部13，导油部13为导油体1的从导油侧表面11至储油侧表面12向导油侧表面11平移0.5mm～1.5mm处之间的部分；导油部13的导液量为2.5mg～12mg，例如，导油部13的导液量为2.5mg、3mg、3.5mg、4mg、4.5mg、5mg、5.5mg、6mg、6.5mg、7mg、7.5mg、8mg、8.5mg、9mg、9.5mg、10mg、10.5mg、11mg、11.5mg或者12mg。
导油部13能够延长导油体1的吸收和渗透雾化液的路径，增加用于雾化的雾化液量。导油部13可以为导油体1的从导油侧表面11至储油侧表面12向导油侧表面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，导油部13的导液量计算方式为：导油部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。
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。
举例说明导油部13的导液速度的测试方法：将高度为h的干燥的待测导油部13固定于夹具上保持水平，保证导油部13每一条母线都竖直向上，在导油部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油部13上方区域到刚好渗透至导油部13的下方的时间t，t/h即为所测导油体的导液速度，单位为mm/s。
根据本申请的实施例，如图8所示，吸液区的面积＝导油侧表面11的面积＝导油侧表面11的长×宽。
这样，导油部13的导液量能够满足对储油部14的储液量的补充需求，通过控制导油部13的导液量能够使储油部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，又能保证导油部13中的烟油可以及时适量地补充至储油部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，导油体1还包括导油部13，导油部13为导油体1的从导油侧表面11至储油侧表面12向导油侧表面11平移0.5mm～1.5mm处之间的部分；导油部13和储油部14为分体件或一体件。
通过将导油体1分设为导油部13和储油部14，因此导油部13和储油部14可以一体成型，以降低加工难度。或者导油部13和储油部14分体设置，导油部13和储油部14的构造更为多样，提高了导油体1的适用性，且兼顾成本和雾化效率。
导油部13能够延长导油体1的吸收和渗透烟油的路径，增加用于雾化的烟油量，导油部13可以为导油体1的从导油侧表面11至储油侧表面12向导油侧表面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，导油体1还包括导油部13，导油部13为导油体1的从导油侧表面11至储油侧表面12向导油侧表面11平移0.5mm～1.5mm处之间的部分。导油部13和储油部14的材质相同或不同。
导油部13能够延长导油体1的吸收和渗透烟油的路径，增加用于雾化的烟油量，导油部13可以为导油体1的从导油侧表面11至储油侧表面12向导油侧表面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。
通过将导油体1分设为导油部13和储油部14，因此导油部13和储油部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油部13，而采用耐高温的材料制成储油部14。
或者导油部13和储油部14为相同材料制成，但是导油部13和储油部14的横截面积、容积、高度或者形状等参数不同，从而提高导油体1的适用性，且兼顾成本和雾化效率。
具体地，为了保证储油部14的结构强度和耐高温性能，可以将储油部14设置为陶瓷，例如储油部14由一个或多个多孔陶瓷件构成；为了提高导油部1313吸收和渗透烟油的效率，导油部13可以为陶瓷，例如导油部13由一个或多个多孔陶瓷件构成。其中，导油部13和储油部14可以是一体成型的整个多孔陶瓷体。
或者，导油部13和储油部14可以为吸油棉，例如储油部14由一个或多个吸油棉构成，导油部13由一个或多个吸油棉构成，导油部13和储油部14可以一体成型，这样成本较低，且安装空间小。
再或者，导油部13和储油部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，导油部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，导油部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烟油的效率。
根据本申请的一些具体实施例，如图6和图8所示，导油体1还包括导油部13，导油部13为导油体1的从导油侧表面11至储油侧表面12向导油侧表面11平移0.5mm～1.5mm处之间的部分。在垂直于从导油侧表面11至储油侧表面12的方向的平面内，导油部13的正投影面积小于或等于储油部14的正投影面积。
通过将导油体1分设为导油部13和储油部14，因此导油部13和储油部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油部13，而采用耐高温的材料制成储油部14。
导油部13能够延长导油体1的吸收和渗透烟油的路径，增加用于雾化的烟油量，导油部13可以为导油体1的从导油侧表面11至储油侧表面12向导油侧表面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。
由于在垂直于从导油侧表面11至储油侧表面12的方向的平面内，导油部13的正投影面积小于储油部14的正投影面积，因此使得导油部13与储油部14之间可以形成位于导油部13周向的台阶面15，既可以提高导油部13的吸液效率，又可以保证储油部14上加热体2对烟油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，储油部14构造成长方体形，导油部13构造成长方体形、梯形台形或三角形台形。具体地，导油部13的设置更为多样，能够适用于不同的使用场景，其中，导油部13的与储 油部14连接一面的为平面，便于储油部14和导油部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，吸液区吸收的烟油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烟油渗透过快而在雾化区以外的低温区域聚集，导致“炸油”，防止漏油，提高了吸液区吸收烟油的利用效率，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烟油的利用效率；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，导油侧表面11构造成平面、折线形曲面、弧形曲面或者球形面。其中，导油侧表面11为平面时，导油侧表面11的形状更为规则，便于加工制造；导油侧表面11为折线形曲面、弧形曲面或者球形面时，可以增大储油部14上吸液区的吸液面积，提高吸液效率。
并且储油侧表面12构造成平面、折线形曲面、弧形曲面或者球形面。其中，储油侧表面12为平面时，储油侧表面12的形状更为规则，便于加工制造；储油侧表面12为折线形曲面、弧形曲面或者球形面时，可以增大储油部14上雾化区的发热面积，提高雾化效率，使得雾化区上烟油的雾化体积量可以达到储油侧表面12上烟油体积的95％～98％，有效避免雾化冷凝液的产生。
如图4-图5给出了储油侧表面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12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套设于导油体1，雾化芯密封件3设有通油口31，导油侧表面11的至少一部分从通油口31露出以形成吸液区。
这样，一方面通过雾化芯密封件3可以密封导油体1的周向的间隙，从而避免储油腔41内的烟油不经过导油体1而直接通过导油体1的周向间隙泄漏到雾化腔42内，保证了烟油的雾化率，进而保证了烟油的利用率，另一方面通油口31的设置，能够使储油腔41内的烟油与导油体1接触，以便于烟油通过通油口31流到吸液区。
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。
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，能够匹配单口雾化所需油液量，从而既能保证出雾量，又能保证油液被充分雾化。
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。
