Description

加热雾化组件、加热雾化装置及其电子雾化器 技术领域
本发明涉及电子雾化装置，尤其涉及一种加热雾化组件、加热雾化装置及其电子雾化器。
背景技术
目前发热体竖向放置的导液芯产品在雾化体验上较好，得到了广泛运用，而市面上主要分为几大类，一类是储液仓内填充储液棉，这种雾化器优点是不容易漏油、缺点是储液棉占用体积较大，烟液没法全部抽完有浪费，看不到剩余油量，因此大多用在低端的一次性产品上；一类是储油仓内无储液棉的结构，由于烟液压力一直存在，通过在安装支架上设进液口，其他位置密封的方式来控制进液，而在加热雾化组件内，导液棉相当于一个三维的的多孔材料，内部微孔间隙都是相通的，当烟液自身重力和储油仓压力大于导液棉毛细现象的吸附力时烟液就容易从导液棉处渗漏。
现有的加热雾化组件采用通过安装支架上设进液孔，其他位置密封的方式来控制进液量，进而降低漏油风险；现有的安装支架主要分为两种，一种是单层支架，另一种是双层支架；单安装支架，通常设置单导液棉，这类结构组成较少，结构简单好装配，但存在一个问题，长时间静置再次抽吸时，导液棉表面烟液较多，产生炸油较为严重，影响体验，而且这个电池满电和缺电状态口感差异也较大；双层安装支架，通常设置双导液棉，双层支架之间夹一层导液棉来降低来自油仓的压力，相当于与发热体一侧的导油棉从外侧的那一层导液棉上吸油过来，可以有效的降低漏油的风险，但是这个结构 组装复杂，对零件尺寸要求很高，如果双层支架的间隙不一或者是位置不对就会造成导液不顺畅，导致部分雾化区的供油不足，引起干烧风险，而且零件成本较高，组装麻烦，效率低，还有就是受电池满电和缺电状态下输出功率的影响，口感差异很大。

实施例1，如图1-5所示，一种加热雾化组件20，包括中空筒状结构的安装支架1，安装支架1内设有筒状的导液体2，导液体2内贴附或镶嵌有发热体3，发热体3连接有电极6；导液体2包括至少两组导液棉21，相邻两组导液棉21之间设有用于控制相邻两层导液棉21之间导液量的隔离件4；安装 支架1侧壁设有用于向导液棉21导液的进液口11；隔离件4上开设有用于多个向导液棉21导液且可形成油膜的平面孔41；导液棉21均为多层导液布重叠卷成的筒状结构，导液布上设有用于导液的微棱或微槽22。
加热雾化组件20的实施过程：烟液由安装支架1的进液口11进入加热雾化组件20，经靠近安装支架1的一组导液棉21，通过外侧导液棉21上的微棱或微槽22向内进行导液，然后导至隔离件4，烟液通过平面孔41向靠近发热体3的一组导液棉21传导，并且在平面孔41上形成油膜，油膜控制烟液过多的向发热体3传导，平面孔41内的烟液缓慢变平，减缓烟液传导到内侧的导液棉21上，同时形成的油膜内可存储烟液相当于一个储液空间，当内侧的导液棉21上烟液较少时，储液空间的烟液快速补充，发热体3将传导至靠近导液棉21上的烟液雾化，形成雾化蒸汽，最后经发热体3的中空内腔流出安装支架1。
安装支架1主要起着固定支撑发热体3和导液体2的作用，故而其需要有一定的支撑强度，防止发热体3和导液体2受力变形导致两者接触不良，从而避免影响雾化效果，安装支架1侧壁设有用于向导液棉21导液的进液口11，进液口11可以设置一个，也可以设置多个，优选设置多个，多个进液口11沿安装支架1外壁周向呈规律间隔设置，控制进液口11的大小可以控制烟液与导液棉21的接触面积。
发热体3包括发热线路31和电极连接件32，电极连接件32连接电极6，电极6给发热线路31供电使其发热，从而雾化与发热线路接触的导液体2上的烟液，导液体2包括至少两组导液棉21，可以设置两组，可以设置三组，甚至更多组，其中最外侧的一组导液棉21与安装支架1接触，最内侧的一组导液棉21与发热体3接触，导液棉21为多层导液布重叠卷成的筒状结构，导液布上设有 用于导液的微棱或微槽22；最外侧的一组导液棉21传导烟液，同时堵住进液口11，导液棉21内的微棱或微槽22，可以传导烟液；最内侧的导液棉21的作用是与发热体3贴合，使得烟液充分的传导到发热体3上，因此该部分的导液棉21需要采用耐温较高的材质，如亚麻纤维棉、芳纶纤维棉等。
如图6-8所示，导液布包括至少一层竖纹导液布212或/和至少一层横纹导液布211，导液布可以设置一层，也可以设置多层，导液棉21上的每一层导液布可以是横纹导液布211，导液棉21上的每一层导液布也可以是竖纹导液布212，导液棉21上的导液布可以同时设有横纹导液布211和竖纹导液布212，竖纹导液布212设有总体竖向排布的纹路形成的微槽22或/和微棱，总体竖向排布指的是导液布的整体纹路上是从上端延伸至下端，但不要求每一条纹路都是由上往下贯通设置，也可以是在竖向纹路基础上向外延伸出分支纹路，优选至少贴附或嵌接发热体3的导液棉21为竖纹导液布212，且竖纹导液布212上设置的竖向纹路与发热体3形状至少部分配合一致，这样发热体3的竖向发热线路可至少部分嵌入到竖向的微棱或微槽22内，从而增大了发热体3与导液棉21的接触面积，进而提升雾化效率；横纹导液布211设有总体横向排布的纹路形成的微槽22或/和微棱，总体横向排布指的是导液布的整体纹路上是从左侧延伸右侧，但不要求每一条纹路都是由左往右贯通设置，也可以是在横向纹路基础上向外延伸出分支纹路；横纹导液布211的纹路可以是以进液口11为中心向两侧辐射，这样的设计可以使进入进液口11的烟液进入导液布后能快速的沿两侧沿周向传导；或者横纹导液布211的纹路在进液口11附近的密度大于其他位置密度，设有设计使得进液口11处的导液速率高于其他位置；或者横纹导液布211的纹路均匀横向排布；优选至少贴附安装支架1的导液棉21为横纹导液布211，横纹导液布211总体横向 排布的纹路可形成的横向的微槽22、微棱，微槽22、微棱部变成横向的导液通道，使得烟液更好导向四周，提高了导液效率，提升使用者吸食体验感。
如图9-11所示，在相邻的导液棉21之间这有隔离件4，隔离件4上设有多个平面孔41，孔的形状不做限定，可以是直线型孔，也可以是曲线型孔，也可以是直线型和曲线型的组合孔，使得烟液只能通过平面孔41从外侧的导液棉21传导至内侧的导液棉21，隔离件4的设置可以控制进油量，将导液棉21分割成多组，使得原来的进液通道减少，可以理解的，相当于隔离件4上非平面孔41部分所占面积的大小就相当于是缩小了多少的进液面积，有效的防止了漏油的问题；隔离件4上设置的平面孔41由于毛细现象形成油膜，阻隔控制烟液过多的向发热体3部分传导，使得外侧导液棉21传导过来的烟液在经过平面孔41时，平面孔41内的烟液有变平的趋势，可以减缓烟液传导到内侧的导液棉21上，同时形成的油膜内可存储烟液，相当于一个储液空间，当内侧的导液棉21上烟液较少时，储液空间的烟液又可以快速补充，从而减缓储液仓60的压力；同时隔离件4距离发热体3较近，隔离件采用金属材料或吸热导热材料制成，可以吸收部分发热体3的热量，避免了发热体3温度升高而糊芯、炸油，同时热量通过隔离件4均散开来，使得其周边导液棉21上吸附的烟液因温度升高而流动更好，使得烟液供应更加顺畅，有效的防止糊芯，有效改善炸油声，结构简单，易于组装，提升雾化口感。
由于隔离件4离发热片较近，因此需要采用耐温较高的材质或吸热导热材料制成，可以采用薄金属网、硅胶网、耐高温塑胶薄片、云母片等材质制成，优选隔离件4为网状结构的金属编织件、网状结构的硅胶件，因为这两种材质的隔离件不仅具有良好的锁液效果，还可耐高温，且隔离件4具有一定的柔性以使其可卷曲成与导液棉21相匹配的筒状结构，可以理解的，隔离件4可以为 片状隔离件4卷曲形成的筒状结构，该筒状结构的隔离件4在侧面可以具有开口的半闭合筒状，也可以是完全闭合的筒状结构；隔离件4设置为与导液棉21同样宽度的片状结构，将内侧的导液棉21、隔离件4、外侧的导液棉21依次重叠，然后一起包卷曲成筒状装入到安装支架1内，减少了零件和组装工序，组装更方便、简单；当然隔离件4还可以是一体成型的筒状结构，一体成型的筒状结构隔离件4安装时，需将内侧的导液棉21、发热体3装至筒内，再装外侧的导液棉21包裹，最后全部一起装至安装支架1内，组装工序较多，但是效果稳定更好，一体成型的隔离件4结构强度更好，因为导液棉21和发热体3都是软质的结构，一体成型的筒状结构的隔离件4可以起到很好的支撑强度，保证了一致性较好。
隔离件4上的平面孔41呈规则间隔排布，如对称排布、阵列排布、等距间隔排布；或者隔离件4上的平面孔41任意排布，隔离件4上的平面孔41孔径大小可以一致，也可以不一致，优选隔离件4上所有平面孔41为大小一致的孔，且呈阵列分布，使得方便批量化生产，且使得隔离件4传导至最内侧导液棉21上各处的导液速率基本保持一致。
隔离件4的厚度会影响烟液的通过性，厚度偏薄会导致锁油效果不明显，可以理解为厚度越薄越难形成油膜，也就是内外侧的导液棉21之间还是接触状态，隔离件4并没起到控制烟液流动的作用，因此起到的锁油效果并不明显，而隔离件4太厚使烟液通过效率变慢，影响通过性；因此，隔离件4的厚度为0.03-2mm，隔离件4的厚度太薄会导致其材料强度不好，另外还影响其锁油效果，难以实施，隔离件4的厚度太厚影响烟液通过效率，也不易实施，优选隔离件4的厚度为0.05-0.3mm；另外，优选厚度大的隔离件4上的平面孔41的孔径比厚度小的隔离件4上的平面孔41的孔径大，这样有利于形成油膜。
隔离件4可以设置多个，将导液棉21分隔成多组，如设置n个，多个隔离件4分别夹杂在导液棉21的不同位置，将导液棉21分为n+1组，优选隔离件4设置1-5个，更优选设置1-2个。将导液棉21分为n组，至少最外侧的导液布为横纹导液布211，至少最内侧的导液布为竖纹导液布212，最外侧的导液布为横纹导液布211可以将进液口11的烟液沿最外侧的导液棉21的周向传导，使得导液更顺畅，最内侧的导液布为竖纹导液布212可以使得发热体3与导液棉21更好的贴合，使得部分发热体3能嵌入最内侧的导液棉21中，提高雾化效率。
隔离件4可以是为单层结构；或者隔离件4为多层结构，隔离件4为多层结构时，优选至少靠近最外侧的导液棉21的隔离件4上的平面孔41孔径大于靠近最内侧的导液棉21的隔离件4上的平面孔41孔径，孔径越大，烟液的通过速率越快，意味着，由外到内的导液速率是逐渐减慢的，这样设计即能控制进液量，防止漏油，又能顺畅导液，从而提高雾化体验感。
下面通过具体实施例对本发明作进一步说明。

综上可知：
1.隔离件4上平面孔41的面积和网孔占比对加热雾化组件20的供液量影响较大，40目平面孔41孔径较大，烟液隔离阻挡效果较小，供液量较大，优选隔离件为60目平面孔41，隔离件为60目平面孔41时，烟液隔离阻挡效果较好，使得口感较好，烟气干湿度适中，明显改善炸油声；
2.隔离件4起到的吸热功能效果较为明显，功率范围有较大提升；

针对以上的实施例的加热雾化组件20：主要从雾化的气溶胶物质的口感(味道还原度)、干湿度、静置一段时间后再抽吸时炸油声(这个主要是判断供液是否过多，炸油声的出现表示供液过多，或者说是密封性能，炸油声的出现表示密封性能变差)、输出功率(主要是调整电池的输出功率看低功率的时候味道是否释放，高功率是否出现糊芯，来判断加热雾化组件20适用的功率范围)，检测结果见下表：

由以上结果得出结论：
1.隔离件4的厚度会影响烟液的通过性，厚度薄稍锁油效果不明显，可以理解为厚度太薄很难形成油膜也就是内外侧的导液棉21之间还是处于接触状态，因此起到的锁油效果并不明显，而厚度太厚对烟液通过性影响较大，优选隔离件的厚度0.15mm，此时烟气干湿度适中，口感较高，锁油效果明显。
2.隔离件4上不同形状的平面孔41对加热雾化组件20的雾化效果的影响并不大。
