Description

加热雾化芯及其电子雾化装置 技术领域
本发明涉及雾化技术领域，尤其涉及一种加热雾化芯及其电子雾化装置。
 背景技术
电加热雾化技术为近年来兴起的新型的雾化技术，其原理是通过电阻的热效应产生热能，热能再将液体加热雾化成为雾化蒸汽，现在广泛的应用在医疗、智能家电、消费电子类产品上。目前应用在电子烟行业内的雾化组件，按其导液介质来区分主要有导液棉之类的软性导液材质和多孔陶瓷类的硬质导液材质，其中，导液棉因其较软的导液材质、孔隙率高，导液性能好，其口感还原度高被广泛使用在雾化行业。
但当前的具有导液棉的电子雾化装置存在以下缺陷：当导液棉面积较大时，四周受力压紧，而中间部分未受力鼓起，这样会导致被压紧的四周部分导液间隙较小，而未被压紧限位的中间部分会鼓起存在较大的间隙，容易造成导液棉的各部分导液间隙不一致，而间隙过大会造成导液棉锁液能力下降，雾化液容易受自身重要影响渗漏滴落；导液棉雾化芯在配合平面状的发热体使用的时候，由于其较为柔软具有弹性，在使用过程中各部分受压力状况不同会造成导液棉内间隙大小不同，会有漏油问题发生，且发热体温度较高，在持续使用时非常容易出现糊芯的问题。

 本发明的实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
部件被称为“固定于”或“设置于”另一个部件，它可以直接或者间接位于该另一个部件上。当一个部件被称为“连接于”另一个部件，它可以是直接或者间接连接至该另一个部件上。
术语“上”、“下”、“左”、“右”、“前”、“后”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置为基于附图所示的方位或位置，仅是为了便于描述，不能理解为对本技术方案的限制。术语“第一”、“第二”等仅用于便于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明技术特征的数量。“多个”的含义是两个或两个以上，除非另有明确具体的限定。
本发明中，横向指上盖的两个进液口连线所在的方向，竖向是垂直与两个进液口连线的方向。
实施例1，如图1-图21所示，一种加热雾化芯，包括上盖10和底座50，上盖10和底座50之间依次设有导液棉30、加热体40，上盖10设置有用于压住导液棉30的压棉件20或上盖10与导液棉30之间设有压棉件20，压棉件20至少包括抵压导液棉30顶面的至少一个压条21，压条21与导液棉30抵压的抵压面形成平面结构，本发明底座50开设有气流进气孔51，压棉件20留有与进液口111连通的进液通道201。通过设置压棉件20，压棉件20上设置压条21，使得压条21压住导液棉30，由于压条21的抵压面形成一个平面结构，本发明所述的压条21的抵压面形成平面结构指：压条21底面在一个平面上，或多个压条21的底面都在一个平面上。压条21抵压使得导液棉30的进液面即顶面形成平面结构，避免了导液棉30只在四周受力，受力不均而变形，导液棉30受力均匀，导液间隙大小一致，导液棉30具有良好的锁液能力，进而避免了因导液棉30导液间隙变大导致的雾化液渗漏滴落，且不易出现糊芯，优化了雾化效果，提升了雾化口感；加热雾化芯工作时，雾化液由上盖10处进入与进液口连通的进液通道，空气由底座50的气流进气孔51进入，雾化液经压棉件20进入到导液棉30，加热体40发热产生热量，将导液棉30中的雾化液雾化形成雾化蒸汽，雾化蒸汽与进入的空气混合形成气溶胶，气溶胶最终被使用者吸食。
上盖10与底座50之间对应配合，主要用于容置导液棉30和加热体40，二者的外部形态可以不作限定，上盖10包括盖体11和可以容置导液棉30的容置部12，容置部12设有内腔121用于与底座50配合容置导液棉30和加热体40。压棉件20设置在盖体11上或设置在容置部12的内腔121中靠近盖体11，即压棉件20与上盖10可以是各自单独的结构，生产时单独建模，建模更简单，这种结构中，压棉件20通过上盖10约束或被上盖10压在导液棉30上。压棉件20形状与上盖10的容置部12的内腔121或/和导液棉30顶部形状配合，压棉件20放置在容置部12的内腔121中，位于盖体11与导液棉30顶部之间。上盖10与底座50二者紧配合插接或卡扣连接成为整体。
另外，压棉件20与上盖10之间还可以是二者连接在一起，二者之间为可拆卸连接或者固定连接，其中可拆卸连接为上盖10的盖体11为框架结构，压棉件螺接、卡接、销接、紧配合嵌接在盖体11内。固定连接方式可以为压棉件20固定在盖体11壁面上。再者，压棉件20与上盖10也可为一体结构，压棉件20位于容置部12的内腔中，该结构在生产时无需多次建模，只需进行一次建模，同时也省略了组装步骤。
压棉件20的结构外形的实施方式具有多种：压棉件20可以是比较薄的扁平结构，使用具有一定强度的金属制成；如图3所示，压棉件20也可以是具有一定厚度和强度的立体结构，制作材料不做具体限制。
压棉件20的主要结构包括压条21，压条21设置数量可以是一个，也可以是多条，设置一个时，压条21优选经过导液棉30顶面中心或中心附近，设置多个时，至少一个压条21优选经过导液棉30顶面中心或附近。这样才能实现对导液棉30顶面边缘和中心都进行抵压。设置一个压条时，可以选择压条宽度较宽，也可以在压条21上的任意位置向外延伸有支条，扩大压条21抵压面积，优选在压条21两端设有支条。同样，设置多条压条21时，也可以在压条21上设有支条。但是压棉件20或压条21不能覆盖全部导液棉30顶面或堵塞进液口111，压棉件20需要留有与进液口111连通的进液通道201。为了能更好实现抵压，优选设置多个压条21，多个压条21可以均布导液棉30顶面，均匀抵压导液棉30。
压条21形状具有多种实施方式：压条21的横截面呈多边形、曲线形或它们的组合，即压条21的形状可以是长方体，可以是圆柱体，可以是多面体，或者是圆柱体压条21与长方体压条21的组合，或者是圆柱体压条21与多面体压条21的组合，又或者是长方体压条21与多面体体压条21的组合，压条21的形状不做具体限定。如图4-11所示压条21的直径或宽度可以是相同的，为等径压条，如图12所示压条21的直径或宽度可以是不相同的，为变径压条，变径可以是在任何位置，且可以是逐步增大或减小，也可以任意变径，本发明不作限定。
压条21走向的实施方式具有多种：如图4-图17所示，压条21可以是横向压条211、也可以是竖向压条212或是斜压条213中的至少一种。由于上盖10设有至少一个用于雾化液进入的进液口111，进液口111贯通上盖10顶面通入容置部12的内腔121。优选上盖10两侧对应设置两个进液口111，雾化液是从上盖10两侧的进液口111进入，灌注到导液棉30的顶面，进入内腔121的雾化液在横向上向中间汇集，所以压条21的走向影响雾化液的流动速率，横向压条211、斜压条213可以使得雾化液在横向上能够顺畅的到达导液棉30的各个位置，竖向压条212会使减慢长度方向的雾化液流动速率，因此优选多设置横向压条211、斜压条213。压条21的设置是为了能将导液棉30抵压形成平面结构，即使得导液棉30的进液面（顶面）形成平面结构，这样导液棉30被压紧后各个部分的间隙差异较小，不会出现差异较大的松紧的状况，使得导液棉30的导液一致性较好。
横向压条211、竖向压条212、斜压条213可以独立设置，也可以是任意组合设置。例如：横向压条211与竖向压条212组合，竖向压条212与斜压条213组合，横向压条211与与斜压条213组合，横向压条211、竖向压条212、斜压条213三者组合。
压条21排布有多种实施方式，如图4-图17所示，横向压条211、竖向压条212以及斜压条213各自的排布呈直线、曲线或者它们的组合，多个压条21之间呈规则顺序、对称排布，也可以是无序任意排布。曲线指任意曲线，例如弧形、抛物线、螺旋等任意曲线结构，组合可以是多个直线相接，形成折线结构、直线枝状结构等，曲线与曲线组合形成的波浪形、曲线枝状结构等，又或者是直线与曲线的组合，具体排布方式不做限定；在一个具体实施例中，压棉件20包括一个竖向压条212和一个横向压条211，压条21压住设置在下方的导液棉30，使得一整块面积较大的导液棉30被分解为4个等面积的导液棉30，这样导液棉30各个部位被压缩的较为一致，使得导液棉30的导液间隙大小一致，使得导液棉30具有良好的锁液能力。
压条21是本发明压棉件20的基础结构，在上述结构的基础上，可以在压条21四周设有边框22，边框22形状和位置与导液棉30顶面形状配合一致。如图4-图6所示，压棉件20为单独的压条21抵压导液棉30。如图7-图15所示，压棉件20包括压条21、压条21四周设有的边框22，边框22与压条21连接成一个抵压导液棉30的整体。
如图4所示，压棉件20包括两条直线形的横向压条211和一条竖向压条212，竖向压条212对应导液棉30顶面中心。如图5所示，压棉件20包括两条曲线形的横向压条211和一条直线形的竖向压条212，直线形的竖向压条212对应导液棉30顶面中心。如图6所示，压棉件20包括两条直线形的斜压条213，两条斜压条213相互交叉设置，直线形的斜压条213中心交叉点对应导液棉30顶面中心。
如图7所示，压棉件20包括两条直线形的横向压条211和边框22，两条直线形的横向压条211对应导液棉30顶面中心附近。如图8所示，压棉件20在图4基础上增加了边框22。如图9所示，压棉件20在图7基础上两条直线形的横向压条211改为曲线形的横向压条211。如图10所示，压棉件20包括三条直线形的斜压条213和边框22，中间的直线形的斜压条213对应导液棉30顶面中心。如图11所示，压棉件20在图6基础上增加了边框22。如图12所示，压棉件20在图8基础上两条等直径的直线形的横向压条211改为非等径的横向压条211，横向压条211的直径向中心逐步减小。如图13所示，压棉件20包括四条直线形的斜压条213、竖向压条212和边框22，斜压条213一端连接边框四角，另一端延伸至导液棉30顶面中心附近，竖向压条212经过导液棉30顶面中心。如图14所示，压棉件20包括四条直线形的斜压条213和边框22，斜压条213一端连接边框四角，另一端延伸至导液棉30顶面中心附近。如图15所示，压棉件20在图9基础上增加竖向压条212，竖向压条212对应经过导液棉30顶面中心。如图16所示，压棉件20包括边框22、两条曲线形的横向压条211。如图17所示，压棉件20在图16基础上增加竖向压条212，竖向压条212对应经过导液棉30顶面中心。
如图18-图21所示，在上述加热雾化芯的基础上，还可以在导液棉30与加热体40之间设有多孔陶瓷件60，多孔陶瓷件60的底面与加热体40贴附；加热雾化芯的进液端采用较软的、孔隙率高导液性能好的导液棉30作为导液介质，与加热体40接触的部分采用多孔陶瓷件60作为导液介质，进液端采用了导液棉30来提升导液和锁液的效率，使得加热雾化装置在供油充足的情况下导液棉30能填充零件之间的间隙，起到很好的锁油防渗出的问题，导液棉30起到快速导液和锁液的功能，由于导液棉30具有柔软性，其还可以填充在多孔陶瓷件60和加热雾化芯其他部件之间的缝隙中，可以有效的密封防止液体在缝隙中渗漏，因此还可以省去硅胶和装配硅胶的工序；多孔陶瓷件60为耐高温、具有固体形态的硬质材质导液体，其可作为无强度的加热体40的载体，这样相当于多孔陶瓷件60整个平整的面压在导液棉30上，使得导液棉30被均匀的压紧，导液更加均匀，优化导液效率，且将加热体40贴附于多孔陶瓷件60底面，这样加热体40和导液体接触良好，加热体40不易变形，而且多孔陶瓷件60耐高温不会碳化，使用寿命大大提高。
加热体40一般采用不锈钢、镍铬、铁铬铝、镍铁等电阻率较高的合金制成，厚度可在0.03-0.2mm之间，具体厚度不做限定，加热体40可以采用金属片材通过腐蚀切割工艺形成加热轨迹镶嵌在多孔陶瓷件60底面或者通过厚膜印刷将加热轨迹印刷在多孔陶瓷件60的底面，多孔陶瓷件60为薄片结构，如厚度在0.1-2mm之间，设计较薄的目的是防止多孔陶瓷件60的多孔网状结构阻挡烟油中大分子的通过性，只是利用多孔陶瓷件60强度好、耐高温、不易碳化、能支撑固定住加热体40，避免了与加热体40接触不好的情况出现。
多孔陶瓷件60顶面的形状与导液棉30底面的形状配合一致，这可使得导液棉30的底面与多孔陶瓷件60抵接得更紧密，使得导液棉30被压紧后各个部分的间隙差异更小，不会出现差异较大的松紧的状况，使得导液棉30到多孔陶瓷件60的导液一致性更好；多孔陶瓷件60底面的形状与加热体40的发热线路形状配合，使得二者紧密贴合，避免了多孔陶瓷件60与加热体40接触不好的情况出现，使得加热体40发热线路产生的热量最大程度用于加热多孔陶瓷件60上的雾化液，优化雾化效果，提升雾化口感。
多孔陶瓷件60开设加快液体传导的导液孔、导液槽62、导液腔中的至少一种；导液孔、导液槽62或导液腔的设置加速了雾化液的传导，减少液体在多孔陶瓷件60中传导的路径，可以提高烟油中一些大分子的通过性。如图21所示，本实施例采用了导液槽62。
如图19所示，多孔陶瓷件60顶部设有凹凸部61，导液棉30底部与凹凸部61嵌接，在此嵌接分别指：导液棉30直接嵌接在凹凸部61中，或者导液棉30底部也同时设置凹凸结构31，该凹凸结构31与凹凸部61形成配合，即二者凹凸配合，具体地，凹凸部61为在多孔陶瓷件60顶面设置的至少一个凹槽或/和至少一个凸起，导液棉30底部设有凹凸结构31，导液棉30的凹凸结构31与多孔陶瓷件60顶面的凸起或者凹槽嵌接，这样可以使得导液棉30与多孔陶瓷件60的接触面积增加，有利于优化导液效果，同时还可以根据实际需要调整导液棉30与多孔陶瓷件60的薄厚以此达到所需的导液效果。
如图20所示，导液棉30进一步优选开设有用于存储液体的储液孔32、储液槽、储液腔中的至少一种；其中储液孔32为贯通导液棉30顶部与底部的通孔，所述储液槽指在导液棉30顶部开口的槽体，储液腔指设置导液棉30内部，为相对封闭的腔体。上述结构可使导液棉30内存在更多的储液空间，储存更多的雾化液，以供给下方的多孔陶瓷件60可以快速的吸收，从而可以保证连续工作时雾化液的供给较为充足。本实施例采用储液孔32。
实施例2，如图22-图23示，一种电子雾化装置，包括雾化器外壳100，雾化器外壳100内设有实施例1的加热雾化芯200，在雾化器外壳100与加热雾化芯200之间设有储液腔300。电子雾化装置工作时，储液腔300中储存有雾化液，储液腔300给加热雾化芯200导液，空气进入雾化器外壳100，空气流经加热雾化芯200，加热雾化芯200将雾化液雾化形成雾化蒸汽，空气与雾化蒸汽混合形成气溶胶，气溶胶流出雾化器外壳100，最终被使用者吸食。
电子雾化装置的其他结构可以采用现有技术，在此不再赘述。
