Description

 本发明的最佳实施方式
本发明横向导液的雾化器，与电池组件连接可以组成电子烟。为便于行文描述，如图3所示将该横向导液的雾化器的吸口10朝上竖直放置，本文所述有关各部件的“上、下、上部、下部、上端、下端、上面、下面、向上、向下”等描述，均是指在吸口朝上竖直放置时的上下位置关系。
本发明的实施方式
下面将结合附图通过具体实施例对本发明进行详细说明。
实施例1：
如图1-图4所示，本实施例的横向导液的雾化器，设有外壳1，外壳1的内上部设有储液腔13，外壳1的内底部套接设有底座4和电极座5，外壳1的中心设有上下连通且与储液腔13分隔的气流通道7，气流通道7内设有雾化腔201，雾化腔201内横向架设有雾化芯3。底座4的上端面连接设有雾化芯座2，雾化芯座2的内部设有上下贯通的雾化通道20，雾化通道20为气流通道7的其中一段，雾化腔201设于雾化通道20的下部。具体是，外壳1的上端设有吸口10及下端设有开口12，吸口10向外壳内延伸设有出雾管11，开口12内套接设有底座4和电极座5，出雾管11的下端连接设有雾化芯座2，出雾管11与雾化芯座2的连接处还设有密封套8。雾化芯座2的下端连接底座4，外壳1的内壁与出雾管11、雾化芯座2和底座4之间的空腔构成储液腔13，底座4由软性材料如硅胶制成，以便与壳体1的内壁、以及与雾化芯座2的底部形成密封连接，防止储液腔13的雾化液泄露。雾化芯座2的两侧分别设有连通储液腔13的进液通孔210，雾化芯座2的内部设有上下贯通的雾化通道20，雾化通道20的下部设有雾化腔201，雾化腔201内横向架设有雾化芯3，雾化芯3的两侧设有空隙使雾化通道20保持上下连通。雾化芯3内部设有横向的中心通孔30，中心通孔30的两端连通并正对进液通孔210，即进液通孔210将储液腔13与中心通孔30连通。
如图5、图6、图7所示，图5为雾化组件，包括密封套8、雾化芯座2、雾化芯3、底座4的组合结构。雾化芯座2为上小下大的结构，雾化芯座2的上端套接于出雾管11的下端，中部内径及外径均扩大，底端形成为一压盖23，压盖23的外侧壁与外壳1的内壁套接，压盖23抵接于底座4上。雾化芯座2的内底部即雾化腔201的两侧分别嵌设有支撑块21，进液通孔210设于支撑块21上，雾化芯3的两端分别连接于支撑块21的内侧，雾化芯座2由硬质材料如塑胶制成，支撑块21由软质材料如硅胶构成，雾化芯座2与支撑块21一体成型制成。其中，雾化芯座2的两侧设有安装孔22，支撑块21的外侧位于进液通孔210处设有与凸部211，凸部211恰好嵌设于安装孔22内。支撑块21具有支撑雾化芯3以及在雾化芯座2与雾化芯3端部之间起到密封作用，保证储液腔13与中心通孔30连通的同时，隔绝储液腔13与雾化通道20之间的连通，防止漏液。
如图7所示，雾化通道20的上端内侧壁处径向向内设有环形凸肩24，环形凸肩24的下部沿雾化通道20的内侧壁向上设有环形槽25，环形槽25用于阻挡、吸附气雾向上流出时携带的冷凝液滴，避免气雾中未被完全雾化的小液滴或冷凝液滴被吸入用户口中，造成不好的使用体验。
如图1-图5所示，电极座5上设有两个弹性电极51，弹性电极51抵触连接于雾化芯的电极盘33上。电极座5上还设有磁体52，以便使该雾化器与电池组件进行磁力连接。底座4和电极座5的中心分别设有上下连通的进气通道6，进气通道6向上与雾化腔201连通。另底座4上还设有注液通孔40，电极座5上设有柱塞53用于给储液腔13注液后封堵注液通孔40。本发明的雾化器及其雾化芯，结构简单，电极盘33无需焊接引线，可与弹簧电极51进行弹性连接，可非常方便地组装到雾化器内，有助于实现雾化器的自动化生产。
如图8、图9所示，雾化芯3包括多孔体31，多孔体31的一面设为雾化面311，雾化面311上敷设有发热层32，发热层32的两个远端分别连接设有电极盘33，发热层32设有供雾化液或气雾流出的雾化通孔320，储液腔13存储的雾化液可横向进入中心通孔30并渗透至雾化面311，发热层32通电发热时使雾化液蒸发成气雾，气雾散发至雾化腔201。本实施例中的雾化芯3，其雾化面311设于雾化芯3的底部，发热层32加热产生的气雾自雾化芯3的底部散发后经雾化芯3的两侧空隙向上流动。
如图3中自A点为起点的连续箭头方向为雾化液流动的方向，即雾化器工作时，雾化液自储液腔13流动，经进液通孔210进入中心通孔30。本发明的雾化芯3装于雾化器的壳体内，且雾化芯3横向置于雾化腔201中，雾化芯的中心通孔30的两端直接连通至储液腔13，储液腔13中的雾化液即可畅通地流动至中心通孔30内，中心通孔30内的雾化液可向多孔体31四周渗透扩散，使供液迅速充分，保证足够的雾化量，给用户提供良好的吸烟体验。
如图4中自B点向C点的连续箭头方向，为气体流动的方向，即雾化器工作时，外界气体自底座4和电极座5的进气通道6流入到雾化腔201，雾化液在多孔体的雾化面311上被加热雾化，在雾化腔201内产生气雾并被进入的气体携带，继续向上流经雾化通道20、出雾管11、吸口10后被吸入用户口中。上述进气通道6、雾化腔201、雾化通道20、出雾管11和吸口10共同构成气流通道7。
本实施例中，多孔体31为多孔陶瓷体，发热层32为金属镀膜，该金属镀膜由金属纳米镀膜构成，金属镀膜上的雾化通孔320是许多均匀分布且微米级的微通孔320，微通孔320可使多孔体31内的雾化液从金属镀膜渗出并雾化。电极盘33由金属银印刷层构成，金属银具有良好的导电性能和良好的接触效果，且不易分解、具有良好的稳定性能。本发明中的发热层32为金属镀膜，金属镀膜的发热面积很大，同时气雾可无阻碍地从微通孔中释放出来，雾化液的雾化量得到极大的提高；金属镀膜整个面发热，受热均匀，不容易产生积碳与漏液的现象；在高温工作下没有不均衡的热应力，金属镀膜没有断路风险，使得产品的使用一致性得到提升，给用户带来良好的使用体验。
如图10所示，本实施例的发热层32的金属镀膜包括过渡膜321与发热膜322，金属镀膜的外侧还设有保护膜323。过渡膜321与发热膜322、保护膜323相互贴合连接，过渡膜321与发热膜322、保护膜323均设有微通孔便于雾化液渗出并雾化。过渡膜321由金属钛构成、主要不用于发热，发热膜322由金属铂构成、主要用于发热。发热膜322选用铂金属，系因考虑到铂Pt不仅具有较低的电阻率，更重要是因它的化学惰性，可以有效地阻止薄膜与陶瓷基底间在工作高温下的相互扩散导致阻值升高影响雾化芯工作的一致性。过渡膜321钛层不仅可以增强金属铂Pt与基底的粘附性，而且可以在雾化器工作的高温下阻止金属铂与陶瓷基体中的硅材料发生反应生成硅化物。
本实施例中保护膜323由氮化硅材料构成，保护膜323用以保护发热膜322，具有防止发热膜被氧化、腐蚀，同时具有绝缘作用。
实施:2：
如图11所示，在实施例一所述结构特点的基础上，本实施例的多孔体31除雾化面311以外的外表面还设有覆膜层34。由于在雾化设备工作时因雾化通道产生负压，雾化液容易从多孔体31的非雾化面渗漏出来，未雾化的液滴容易被吸入用户口中，造成用户不良体验。该覆膜层34由致密、不可渗透的材料制成，包裹了多孔体31的非雾化面，可避免雾化液从多孔体31渗漏，从而改善上述不足。在本实施例中，覆膜层34由致密陶瓷层构成，多孔体31由多孔陶瓷体构成，两者可由不同的陶瓷基体材料一体成型后烧结制成。
在其他实施例中，覆膜层34也可由金属氧化物镀膜层、或塑胶层、或硅胶层构成。
实施:3：
如图12所示，在实施例一所述结构特点的基础上，本实施例将雾化面311设于多孔体31的底面以及相对的两个侧面，即包括雾化芯3的底面和两个侧面的三个面都可发热雾化，这样可以增加雾化面积、加大雾化量，使用户具有更好的雾化吸食体验。
实施:4：
如图13所示，在实施例一所述结构的基础上，本实施例将雾化芯底部的雾化面311设为圆弧形的曲面，发热膜32以曲面镀膜的形式贴附于雾化面311上，电极盘33由金属银印刷层的形式构成。雾化面311设为圆弧形的曲面，使得在相同空间增加了雾化面积从而增加雾化量，使用户具有更好吸食体验。
实施:5：
如图14、图15、图16所示，在实施例一所述结构特点的基础上，本实施例的雾化芯3，还包括座体34，中心通孔30横向设于座体34的中心，座体34的其中一面沿中心通孔30的方向设有安装凹槽341，安装凹槽341的内部与中心通孔30贯通，安装凹槽341的内侧壁嵌设有耐热且可渗透雾化液的多孔体31，多孔体31向外的一面设雾化面311，有通电可发热的发热层32，发热层32的两个远端分别连接设有电极盘33，电极盘33敷设于发热层32的表面，用于连接提供电源的电极。多孔体31朝向中心通孔30的一面沿中心通孔30纵向设有导液槽312，设有导液槽312可减少多孔体31自导液槽一面至雾化面311的厚度，以便雾化液可以更快地渗透至雾化面311。中心通孔30的两端可将雾化液导入多孔体31内，雾化液可在多孔体31内渗透至雾化面311并被发热层32加热蒸发成气雾。
本发明实施例的座体34由致密陶瓷体构成，多孔体31由多孔陶瓷体构成，两者由不同的陶瓷基体材料成型为一体后烧结制成。发热层32由金属镀膜构成。金属镀膜设有雾化通孔320，雾化通孔320便于雾化液或气雾通过，金属镀膜通电发热时使雾化面311上的雾化液蒸发成气雾并从雾化通孔320散发出来。本实施例的雾化芯设有座体34，使雾化芯3具有更好的密封、绝缘和隔热效果。
在其它实施例中，座体34也可由硬质塑胶体构成，多孔体31也可由微孔玻璃体、或微孔金属体构成，发热层32也可由发热电阻丝、或多孔金属片构成，电极盘33也可由金属片、或金属镀膜构成，电极盘33也可连接电极引线。多孔体31与发热层32之间还可设有绝缘层。在其它实施例中，雾化芯3也可将其雾化面311设于雾化芯3的上部。
