具体实施方式
以下将结合附图及实施例来详细说明本公开的实施方式，借此对本公开如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本公开中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本公开的保护范围之内。
如图1-3所示，本公开提供了一种雾化器，包括储油器主体和雾化芯，储油器主体内形成有用于储油的储油腔101，雾化芯安装于储油器主体内，雾化芯用于雾化储油腔101内的烟油。
如图1-5所示，根据本公开的雾化芯包括雾化芯主体3，雾化芯主体3内形成有气流可通过的加热腔312，加热腔312内设有发热芯314，加热腔312内设置有用于减弱加热腔312内的气流的挡气件313，所述挡气件313沿着气流的流向(如图6中箭头所示)设置在所述发热芯314的上游。需要说明的是，通过在加热腔312内设计挡气件313，气流通过加热腔312前，会受到挡气件313的阻挡将气流量削弱，使整个加热腔312内气压处 于相对平衡，从而显著减轻或甚至消除抽烟时的异响。
应当理解的是，术语“气流通过方向”指的是使用者在抽吸时，气流在雾化芯和雾化器内的气流走向即图6中箭头所示的方向。由于挡气件313沿着气流通过方向位于上游，发热芯314沿着气流通过方向位于下游，所以在使用者抽吸烟雾时，气流会首先经过挡气件313，从而使气流量削弱，然后气流再经过发热芯314进行加热，并携带烟油雾化产生的烟雾离开所述加热腔312，由此使得整个加热腔312内气压处于相对平衡，从而显著减轻或甚至消除抽烟时的异响。
在根据本公开的一些实施例中，发热芯314可以包括但不限于以下材料中的任意一种或任意两种或更多种的组合：陶瓷内嵌加热丝、陶瓷内嵌加热丝外包棉、加热丝外包棉、棉外缠绕加热丝。
在根据本公开的一些实施例中，挡气件313可以是吸油材料和/或透气材料制成的。在挡气件313由吸油材料制成的实施例中，挡气件313可以吸收并保存加热腔312内产生的冷凝液和/或发热芯314产生的漏油。在挡气件313由透气材料制成的实施例中，挡气件313自身就可以在气流通过的同时对气流产生阻力，而可以不额外在挡气件313中开设供气流通过的孔或通道。其中，吸油材料和/或透气材料可以包括但不限于以下材料中的任意一种或任意两种或更多种的组合：有机棉、卫生棉、复合棉、亚麻棉、纤维棉、陶瓷、云母。
在本公开的一些实施例中，挡气件313形成有内部中空的第一通孔315，发热芯314形成有内部中空的第二通孔316，第一通孔315与第二通孔316相对应，气流经过第一通孔315流向第二通孔316。应当理解的是，在挡气件313由透气材料制成的实施例以及在挡气件313由不透气材料制成的实施例中，挡气件均可以形成有所述第一通孔315。需要说明的是，在挡气件313是由如上所述的吸油材料(例如棉材质)制成的且形成有内部中空的第一通孔315的实施例中，挡气件313不仅可以通气流，还可以吸收加热腔312内产生漏油和冷凝液。
在根据本公开的一些实施例中，第一通孔315的尺寸小于第二通孔316的尺寸；挡气件313的外壁与加热腔312的内腔壁相互抵接。实际应用中， 第一通孔315的径向尺寸小于第二通孔316的径向尺寸。需要说明的是，第一通孔315用于削弱进入加热腔312时的气流，第二通孔316用于将削弱后的气流导入加热腔312上段空间内，使加热腔312内处于发热芯314上下两端的加热腔312空间气压平衡，防止抽烟时气流进入加热腔312后由于受到发热芯314的阻挡，造成加热腔312下段空间气压大，上段空间气压小，使加热腔312内气压不平衡，气流通过发热芯314会发生异响。第一通孔315的尺寸小于第二通孔316的尺寸，使得减弱气流的效果更好。
在根据本公开的一些实施例中，加热腔312具有进气端，挡气件313设在加热腔312的进气端。挡气件313的具体位置可以根据需要而定，位于加热腔312的进气流的位置减弱效果较好。在一些实施例中，进气流从加热腔312的下端进入，挡气件313位于发热芯314的下方，挡气件313在由上述吸油材料制成时还可以同时起到吸收漏油的作用，防止漏油。
在根据本公开的一些实施例中，雾化芯主体3包括雾化管301，加热腔312形成于雾化管301内，雾化管301上贯穿设有连通加热腔312且与发热芯314对应设置的进油孔303，进油孔303用于供烟油穿过进入加热腔312内。通过该种设置方式，便于烟油进入加热腔312内被加热形成烟雾。
在根据本公开的一些实施例中，挡气件313与发热芯314沿气流的流向间隔设置，以使在加热腔312内在挡气件313和发热芯314之间形成有间距空间，间距空间连通第一通孔315和第二通孔316；雾化管301上还贯穿设有气孔305以及连通于气孔305的气槽304，气孔305与间距空间对应设置，气槽304形成于雾化管301之远离加热腔312的一侧，以使气体沿气槽304流经气孔305进入间距空间内以及使气体从间距空间经过气孔305流向气槽304。本实施例中，气槽304一端与进油孔303相连通，气槽304另一端与气孔305相连通。可以理解，在其他实施例中，气槽304不与进油孔303相连通也是可以的。
