7、进气通道背离所述雾化部的方向向壳体靠近出气通道一端倾斜，也即进气通道与外露于壳体的一端向出气通道方向倾斜，使得用户在使用时，进气通道的方向朝上，当雾化部内形成油液时，沿着雾化部内壁流动的油液由于进气通道的向上倾斜结构，可回落到雾化部内，进一步避免油液的渗漏。
8、通过在所述储油部与所述雾化部的连通处形成一“U”型通道，所述多孔陶瓷盖合于所述“U”型通道靠近雾化部的一侧上，使得油液通过在雾化部和储油部形成的通道处，改变油液自由下落的流动方向，油液向出气通道方向移动，以被多孔陶瓷吸附，以通过“U”型通道改变油液的流动方向后承受油液的部分重力，降低对多孔陶瓷的压力，提高多孔陶瓷吸附油液的稳定性，避免油液渗漏。
9、多孔陶瓷背离雾化部一侧设有向内凹陷的凹槽，凹槽为多孔陶瓷的自身凹陷结构，以增加多孔陶瓷的表面积大小，也即增加了与油液的接触面积，提高油液的吸附率，让发热件加热的油液更均匀。

具体实施方式
下面结合附图，对本申请的具体实施方式进行详细描述，但应当理解本申请的保护范围并不受具体实施方式的限制。
请结合图1和图2，本申请第一实施例提供一种烟弹1，包括壳体11、多孔陶瓷12及发热件13，多孔陶瓷12及发热件13设于壳体11内，发热件13设于多孔陶瓷12一端。
壳体11包括储油部111和雾化部112，储油部111环设于雾化部112的外周侧，雾化部112一端连接出气通道113，雾化部112相对一端与储油部111连通。
可以理解，所述发热件13为电阻丝等可基于通电发热的设备。
可以理解，储油部111环设于雾化部112的外周侧，也即储油部111包覆雾化部112，储油部111内用于储存油液，油液从外侧的储油部111向内流向雾化部112内，油液经过多孔陶瓷12的吸附后，经过发热件13加热雾化形成气溶胶。
多孔陶瓷12设于雾化部112背离出气通道113一端，且多孔陶瓷12一端靠近储油部111的最低液面处(如图1中p位置所示)设置，多孔陶瓷12的相对一端延伸于雾化部112内。
发热件13设于多孔陶瓷12靠近出气通道113一端，当储油部111的油液与多孔陶瓷12接触后，经过发热件13加热雾化形成气体进入雾化部112。
可以理解，由于储油部111包覆雾化部112，且储油部111在背离出气通道113一侧与雾化部112连通，则储油部111与雾化部112的连通处即形成一“U”型通道100，多孔陶瓷12盖合于“U”型通道100靠近雾化部112的一侧上，使得储油部111流出的油液通过多孔陶瓷12吸附。
可以理解，处于外围的储油部111内的油液从壳体11背离出气通道113一端(也即上述储油部111的最低液面处p)流向多孔陶瓷12，也即多孔陶瓷12的位置低于油液的液面，使得油液通过自身重力作用自储油部111向雾化部112流通，且在壳体11背离出气通道113一端，且靠近多孔陶瓷12的位置形成“U”型流向，也即油液在经过自身重力下降后，通过储油部111与雾化部112之间形成的“U”型通道向上移动至雾化部112，使得在雾化部112位置的多孔陶瓷12吸附油液，油液在多孔陶瓷12的吸附下向上流动(如图2中所述b方向)，最后通过发热件13加热多孔陶瓷12吸附来的油液以产生气溶胶。
可以理解，通过设有储油部111环设于雾化部112外周侧，且在油液最低液面附近设置多孔陶瓷12以吸附油液，使得油液在通过自身重力下降后，经过储油部111的壁面上升移动到多孔陶瓷12吸附，使得储油部111内的油液自身的部分重力被储油部111底部承压，降低了多孔陶瓷12受到的压力，避免了现有的油液的重力完全作用于多孔陶瓷12上导致的多孔陶瓷12易漏油的问题。
可以理解，当油液的作用力完全作用于多孔陶瓷12上，且油液造成的推力大于多孔陶瓷12的吸附力时，多孔陶瓷12吸附的油液就会散落入雾化部112内，使得液体状的油液会被用户吸食，影响用户的正常使用。
可选地，在一些其他实施例中，当所述雾化部112背离出气通道113一侧与储油部111平行设置，且在该侧两者具有间隙时，雾化部112与储油部111 在连通处可形成一“L”型通道，油液也可基于该“L”型通道改变流向后，向上被多孔陶瓷12吸附，油液的部分重力可被“L”型通道的折弯处承压，同样也可以起到降低多孔陶瓷12受到的油液压力。
当然，在其他实施例中，雾化部112与储油部111的联通处还可以形成其他形状的通道，例如形成“N”字型通道，只要可以使油液通过在二者形成的通道处，改变油液自由下落的流动方向，然后被多孔陶瓷吸附即可，在此不再赘述。
请继续参阅图1，雾化部112的口径自出气通道113向多孔陶瓷12方向逐渐增大，使得在雾化部112内产生的气溶胶往出气通道113排出时，经过雾化部112内壁表面遇冷液化的气溶胶可基于弧形结构倒流回到发热体13或多孔陶瓷12内，避免液化的气溶胶被用户吸食，提高了装置使用的安全性。
多孔陶瓷12与雾化部112之间设有密封圈114，以密封多孔陶瓷12与雾化部112之间的间隙，使得沿着雾化部112内壁流下来的油液被密封圈114遮挡，并导流到多孔陶瓷12内，提高装置的密封特性，避免油液的渗漏，提高用户体验。
储油部111与多孔陶瓷12之间还设有支撑柱14，支撑柱一端与储油部111连接，另一端与多孔陶瓷12连接，使得多孔陶瓷12与储油部111底部被支撑柱14撑开一端距离，避免多孔陶瓷12与储油部111底部完全接触，进一步降低了油液对多孔陶瓷12的作用力，提高油液的密封效果。同时，也避免了多孔陶瓷12覆盖储油部111的底部，保证油液的正常流通。
请继续参阅图1，壳体11上还设有进气通道115，进气通道115设于壳体11侧面，进气通道115与雾化部112连通，使得用户在吸食雾化部112内的气 溶胶时，可基于进气通道115与外部连通，吸取外部空气带动气溶胶往出气通道流动，以使雾化部112形成开放式腔体。
可以理解，进气通道115的位置高于多孔陶瓷12的高度，以避免油液渗漏到雾化部112内。
可选地，请继续参阅图1，作为一种实施例，进气通道115的数量为两个，两个进气通道115以雾化部112的轴心中心对称设置，使得进气更均匀，同时也让产品结构更美观。
可选地，作为又一种实施例，进气通道115背离所述雾化部112的方向向壳体11靠近出气通道113一端倾斜，也即进气通道115与外露于壳体11的一端向出气通道113方向倾斜，使得用户在使用时，进气通道115的方向朝上，当雾化部112内形成油液时，沿着雾化部112内壁流动的油液由于进气通道115的向上倾斜结构，可回落到雾化部112内，进一步避免油液的渗漏。
多孔陶瓷12为正方体、长方体、三角体、梯形体、柱体或球体的任一种形状，不同形状的多孔陶瓷12可承受不同方向的油液重力，在本实施例中，多孔陶瓷12为柱体结构，以通过环形结构密封上述的“U”型通道100一端。
特别地，在一些其他实施例中，多孔陶瓷12背离雾化部112一侧设有向内凹陷的凹槽121，凹槽121为多孔陶瓷12的自身凹陷结构，以增加多孔陶瓷12的表面积大小，也即增加了与油液的接触面积，提高油液的吸附率，让发热件13加热的油液更均匀。
本申请第二实施例提供一种气溶胶产生装置，其包括如上述第一实施例中提供的烟弹1。
与现有技术相比，本申请提供的烟弹具有以下优点：
通过设有储油部环设于雾化部外周侧，且在油液最低液面附近设置多孔陶瓷以吸附油液，使得油液在通过自身重力下降后，经过储油部的壁面上升移动到多孔陶瓷吸附，使得储油部内的油液自身的部分重力被储油部底部承压，降低了多孔陶瓷受到的压力，避免了现有的油液的重力完全作用于多孔陶瓷上导致的多孔陶瓷易漏油的问题。
前述对本申请的具体示例性实施方案的描述是为了说明和例证的目的。这些描述并非想将本申请限定为所公开的精确形式，并且很显然，根据上述教导，可以进行很多改变和变化。对示例性实施例进行选择和描述的目的在于解释本申请的特定原理及其实际应用，从而使得本领域的技术人员能够实现并利用本申请的各种不同的示例性实施方案以及各种不同的选择和改变。本申请的范围意在由权利要求书及其等同形式所限定。
