Description

具有软质雾化芯的电子烟雾化器 技术领域
本发明涉及电子烟雾化器的技术领域，更具体的说，本发明涉及一种具有软质雾化芯的电子烟雾化器。
 背景技术
电子烟一般包括电池组件和雾化器，其中电池组件内设有给雾化器供应电源的电池，雾化器包括雾化芯，雾化芯至少包括导液体和发热体，发热体在通电时可将雾化液蒸发成气雾，供使用者吸入口中吸食。雾化液即待雾化的电子烟烟液，电子烟作为雾化液的雾化设备，可将电子烟内储存的雾化液加热蒸发成为气雾、气溶胶、蒸气等供使用者吸入。
现有电子烟雾化器的雾化芯，包括有导液棉绳缠绕发热丝的结构，以及多孔陶瓷加底部发热电阻的结构。其中，导液棉绳缠绕发热丝的结构，由于其导液棉绳可传导雾化液的导通横截面的面积小，工作时雾化量就较小，且在高温工作时因雾化座与导液棉绳密封不良就容易漏液。而多孔陶瓷加底部发热电阻的结构，由于其多孔陶瓷内存在许多无序的微孔，在长时间工作时，电子烟烟液中含有的大分子和微颗粒、糖分等容易聚集、堵塞在多孔陶瓷的微孔内，且在高温下容易产生烧焦的焦味，导致用户吸烟时烟雾量降低、吸烟的口感前后不一致，口味不纯正甚至吸出焦味；另外，多孔陶瓷的制造工艺复杂、成本高、生产效率低；且多孔陶瓷的组成成分复杂，不能排除含有一些重金属的成分，在长时间高温工作下，难免会有析出重金属的风险。
现有电子烟雾化器，一般采用中间直通的气流通道，雾化液中未被雾化的液滴或气雾在管壁上凝聚的冷凝液，容易从雾化器的底盖进气孔泄露出来，或容易被用户吸入口中，导致用户使用体验不良。
另现有电子烟雾化器的雾化组件和配件较多，结构复杂，导致在生产中工艺流程多、装配效率低，不易实现生产的自动化。

 本发明的最佳实施方式
为便于行文描述，如图1所示将该具有软质雾化芯的电子烟雾化器的吸口朝上竖直放置，本文所述有关各部件涉及“上、下、上部、下部、上端、下端、上方、下方、向上、向下”等的描述，均是指在该具有软质雾化芯的电子烟雾化器的吸口朝上竖直放置时的上下位置关系。
本发明的实施方式
下面将结合附图与具体实施例对本发明进行详细说明。
实施例
如图1所示，一种具有软质雾化芯的电子烟雾化器，由吸嘴壳100、套设于吸嘴壳100内壁的雾化头组件200和封堵于吸嘴壳100底部的底盖300组成。
如图1-图3所示，吸嘴壳100包括上端偏离中心轴线处设有的吸口1001，吸口1001的边缘向吸嘴壳内部竖直向下延伸设有吸口管1002，吸嘴壳100的底部具有开口1003，雾化头组件200自开口1003向上套入吸嘴壳100的内壁，底盖300套接于该开口1003的外壁。
如图4所示，雾化头组件200包括雾化上座10、软质雾化芯20和雾化底座30，雾化上座10和雾化底座30上下连接，软质雾化芯20设于雾化上座10和雾化底座30之间的内部，雾化上座10的底部向上凹设有雾化芯容腔1210，软质雾化芯20收纳于雾化芯容腔1210内，雾化底座30向上承托软质雾化芯20。
如图5-图9所示，雾化上座10由气道密封件11、上座支架12和上座密封件13构成，其中，上座支架12的上部设有出气管120，下部设有扁状体121，出气管120的横截面小于扁状体121的横截面，扁状体121的侧壁套装上座密封件13后套接于吸嘴壳100的内壁。扁状体121的底部向上设有凹槽形的雾化芯容腔1210，雾化芯容腔1210用于容纳软质雾化芯20。雾化芯容腔1210的外部两侧设有出气通孔1211，出气通孔1211向上连通至出气管120的内部两侧。雾化芯容腔1210的内部两侧设有进液通孔1212，进液通孔1212连通至扁状体121的上表面且位于出气管120的外部两侧。扁状体121上还设有注液通孔1213，注液通孔1213连通扁状体121的上下两侧，注液通孔1213用于在组装时作为加注雾化液的通道，加注完雾化液后用下文所述柱塞313堵住。
出气管120的上端连接吸嘴壳100的吸口管1002，气道密封件11套接于出气管120与吸口管1002之间以便两者进行密封连接，气道密封件11可由硅橡胶材料制成。气道密封件11的底部套入出气管120的部分，其外径缩小并与出气管120的内壁形成一个倒扣的内环槽110，内环槽110可用于收集、阻挡经出气管120排出气雾中的冷凝液，可防止冷凝液被吸入用户口中。上座密封件13设于扁状体121的侧壁、雾化芯容腔1210的下部端面和注液通孔1213的内壁以便进行密封，即上座密封件13包括设于扁状体121侧壁的部分、雾化芯容腔1210的下部端面部分和注液通孔1213内壁的部分。
在本发明中，上座支架12由硬质塑胶材料构成，上座密封件13由软质硅橡胶材料构成，两者在生产中通过包胶工艺二次成型，制成为一体，这样就可以减少组件和配件，在装配中使得生产工艺流程减少、装配简单，可以提高生产效率，并且有助于生产自动化。
如图10-图14所示，软质雾化芯20包括雾化芯支架21、发热体22和软质导液体23，雾化芯支架21包括上平面211、下平面212以及中间设有的支架通孔210，发热体22包括设有一定形状导电路径的片状的发热电阻221，发热电阻221设于支架通孔210内，本实施例中，发热电阻221与雾化芯支架21的上平面211平齐或大致平齐，软质导液体23设于发热电阻221的上面，软质导液体23的底部与发热电阻221抵接，便于软质导液体23内含有的雾化液接触到发热电阻221，使发热电阻221直接加热雾化液并蒸发成气雾。
本实施例的软质导液体23采用有机棉构成，并制成具有一定粘合力、不易分散的块状，即软质导液体23由块状体构成。在其它实施例中，软质导液体23的构成材料还可以是陶瓷纤维棉、玻璃纤维棉、PP纤维、尼龙纤维、无纺布、PET纤维中的一种或几种混合构成，这些材料均为软质材料。由于软质导液体23采用的上述原材料成本低、不需要烧结、工艺简单及结构简单，容易组装到雾化器，可以极大地降低成本、提高生产效率。另软质导液体23的组成材料成分简单，不含有重金属的成分，故软质雾化芯在高温工作的条件下，没有重金属析出的风险。
软质导液体23工作时，自上而下传导雾化液，其块状结构使得传导和加热雾化液的面积大，避免了导液棉绳传导雾化液的导通面积小、工作时雾化量较小以及高温工作时容易漏液的缺点。软质导液体23采用上述软质棉状的材料，这些材料均具有疏松的纤维结构，雾化液通过纤维结构之间的缝隙传导，不需要通过微孔传导，故导液快、可以保持较大的雾化量，相对于硬质的多孔陶瓷，避免了雾化液中含有的大分子和微颗粒、糖分等容易聚集、堵塞在微孔内、且在高温下容易产生焦味的缺点。
其中，发热体22还包括发热电阻221两端连接设有的电极接触盘222，电极接触盘222设于雾化芯支架21的下平面且位于支架通孔210两侧，电极接触盘222用于柱状电极33抵接其上进行供电。
发热电阻221和电极接触盘222的两侧设有若干伸入雾化芯支架21内部的固定爪223，固定爪223用于更牢固地固定在雾化芯支架21上。本发明中，雾化芯支架21可以由耐热的塑胶材料制成，发热体22可以在雾化芯支架21注塑成型前置于模具内与雾化芯支架21成型为一体，特别是固定爪223成型于雾化芯支架21内，使两者更加牢固地连接，可以防止发热体22从雾化芯支架脱离。
本实施例中，发热电阻221的导电路径的形状为若干个重复的S形，在其它实施例中，还可以设置为其它任意形状，并不限定为S形状。发热电阻21通常由金属发热电阻构成。软质导液体23可以吸收、存储、传导雾化液，发热电阻221紧贴于软质导液体23的下部，当发热电阻221通电时会发热，将软质导液体23下部的雾化液进行加热、蒸发、雾化成气雾，气雾通过支架通孔210向下散发。
如图15所示，在另一实施例中，软质雾化芯20还包括具有渗透孔（图中未示）的渗透薄片24，渗透薄片24的厚度设置为0.5mm～2mm，渗透薄片24设于软质导液体23与支架21之间，其中，渗透薄片24的渗透孔的直径可设置为50um～2mm。在本实施例中，渗透薄片24起到向上支撑软质导液体23，防止软质导液体23在长时间高温工作下发生变形、向下凹陷的作用，同时还通过渗透孔将软质导液体23存储的雾化液缓释到发热电阻221上，工作时使雾化液的蒸发量与渗透量达到一种平衡，没有雾化时通过渗透孔的雾化液形成表面张力达到另一种平衡，防止雾化液滴漏和跑液。渗透薄片24可以做得很薄，渗透薄片24可以由耐高温、不导电的材料如塑胶、硅胶、多孔陶瓷、硅藻土等材料构成。
如图16-图25所示，雾化底座30由柱状电极33、上下连接的底座支架31和底座密封件32、以及PCB电路板34组成，底座支架31的侧壁和底座密封件32的侧壁套接于吸嘴壳100的内壁，底座支架31的上端连接雾化上座10的下端，柱状电极33竖直穿设于底座支架31的内部，柱状电极33的顶端承托并抵接于电极接触盘222，柱状电极33起到向上承托软质雾化芯20的作用，同时抵接于电极接触盘222用于供电给发热电阻221。
底座支架31位于软质雾化芯20的下方处设有雾化凹槽310，雾化凹槽310的底部设有第三进气孔311，底座支架31的下端一侧向上设有第一进气凹槽312，底座密封件32位于第一进气凹槽312的下方处设有第二进气孔321，第二进气孔321向上延伸设有高出底座密封件32上端面的第二进气孔管壁3210，第二进气孔管壁3210伸入第一进气凹槽312，第二进气孔管壁3210的上端部与第一进气凹槽312的底部之间设有第一进气空隙3121，第二进气孔管壁3210与第一进气凹槽312之间设有第二进气空隙3122，底座密封件32位于第三进气孔311的下方处设有第二进气凹槽322，第二进气凹槽322连通第二进气空隙3122和第三进气孔311。
底座支架31和底座密封件32分别设有用于穿设柱状电极的电极孔330，底座密封件32的底部还设有PCB电路板安装槽340，PCB电路板34安装于PCB电路板安装槽340内，PCB电路板34上设有电极弹簧341，柱状电极33的底端抵接于电极弹簧341上。PCB电路板34上还可设有控制芯片，包括防伪芯片、防儿童使用芯片等。
底座支架31上设有向上凸伸的柱塞313，柱塞313用于在注液后插入注液通孔1213进行封堵而防止漏液。底座支架31上还设有2个第一固定孔314，底座支架31的底部还设有4个第一固定柱315，底座密封件32的上部还设有2个第二固定柱322和4个第二固定盲孔323。第二固定柱322向上穿过第一固定孔314固定，使底座支架31和底座密封件32进行定位安装和固定，第一固定柱315安装到第二固定盲孔323内使底座支架31和底座密封件32进行定位安装和固定。
如图23-图25所示，PCB电路板的下面设有两个PCB电极（图中未示），底盖300上对应于PCB电极的位置设有底盖电极孔3001，PCB电极露出于底盖电极孔3001以便电子烟电池的电极抵接于PCB电极。底盖300上还对应于第二进气孔321的位置设有若干个第一进气孔3002。
如图24、图25所示，吸嘴壳100内部具有空腔，雾化头组件200组装到吸嘴壳100内后，吸嘴壳100的内壁、上座支架12与吸口管1002之间构成的空腔用作储存雾化液的储液腔40。
如图24、图25所示，本发明的电子烟雾化器工作时，用户通过吸口1001吸气，雾化器内部产生负压，外界空气自雾化器的底盖的第一进气孔3002进入第二进气孔321及其第二进气孔管壁3210，然后进入第一进气凹槽312内的第一进气空隙3121，空气在进入第一进气空隙3121后折返向下进入第二进气空隙3122，然后再横向进入底座密封件34的第二进气凹槽322，然后再向上进入第三进气孔311、随即进入雾化凹槽310，此时储液腔40中的雾化液已向下经出气管120外部两侧的进液通孔1212进入软质雾化芯20内，发热电阻221通电发热，将软质导液体23下部的雾化液进行加热、蒸发、雾化成气雾，气雾向下散发进入雾化凹槽310后被进入的空气带动，经出气通孔1211向上流动至出气管120内部，再经吸口管1002、吸口1001流出，最后被吸入用户口中。以上空气流动的方向和路径，如图24中的连续空心箭头所指示。
本发明电子烟雾化器的内部结构，设有包括第一进气孔3002、第二进气孔321、第一进气空隙3121、第二进气空隙3122、第二进气凹槽322、第三进气孔311以及雾化凹槽310的进气通路，该进气通路具有多道曲折的路径结构，使外界进入的空气可以顺利进入，但滴落至雾化腔中的冷凝液则不易向下流出并反向自第一进气孔3002漏出来。
如上所述，本发明的具有软质雾化芯的电子烟雾化器，由于软质导液体采用的原材料成本低、不需要烧结、工艺简单及结构简单，容易组装到雾化器，可以提高生产效率；其软质导液体上下传导雾化液，传导和加热雾化液的面积大，避免了导液棉绳传导雾化液的导通面积小、工作时雾化量较小以及高温工作时容易漏液的缺点，同时软质导液体通过疏松的纤维结构传导雾化液，不需要通过微孔传导，避免了多孔陶瓷工作时，雾化液中含有的大分子和微颗粒、糖分等容易聚集、堵塞在多孔陶瓷的微孔内，且在高温下容易产生烧焦的焦味的缺点，可以保持较大的雾化量、以及口感前后一致、口味纯正，避免吸出焦味，给用户带来更好的使用体验；由于软质导液体采用的软质原材料成本低、不需要烧结、工艺简单及结构简单，容易组装到雾化器，可以极大地降低成本、提高生产效率；另软质导液体的组成材料成分简单，不含有重金属的成分，故软质雾化芯在高温工作的条件下，没有重金属析出的风险。
本发明的雾化器，其进气通路具有多道曲折的路径结构，使外界进入的空气可以顺利进入，但滴落至雾化腔中的冷凝液则不易反向自底盖漏出来。另在气道密封件中设有倒扣的内环槽，可用于收集、阻挡排出气雾中的冷凝液，防止冷凝液被吸入用户口中，给用户带来良好的使用体验。
