Description

雾化芯、雾化器和电子雾化装置
本申请要求于2020年9月18日申请的、申请号为202022053263.2，以及2020年11月23日申请的、申请号为202011323329.3的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子雾化技术领域，特别是涉及一种雾化芯、雾化器和电子雾化装置。
 背景技术
目前雾化器及电子雾化装置已经被广泛应用。常用的一种电子雾化装置，也可以称作气雾发生装置，其包括雾化器和电池主体，雾化器通过螺纹固定于电池主体的上表面，雾化器包括底座，底座的，底座的中心设置烟气通道，烟气通道内设置雾化芯，烟气通道的上部设置有烟嘴，底座的边缘设置有外壳，外壳的内壁和烟气通道的外壁之间围成储液腔，烟气通道开设进液孔，雾化液通过进液孔流向雾化芯，雾化液雾化后通过烟嘴流出。雾化器由雾化芯、气道等组成，工作时，由雾化芯把液体或者半液态的雾化液雾化成具有一定功能成分的气凝胶以供使用，雾化器的工作原理就是让雾化液发生状态变化，从液态蒸发成气态。这个过程由雾化芯来完成，雾化芯由加热体、陶瓷基体等组成，加热体通电工作，将雾化液汽化，陶瓷基体用于导液，还可以用棉花替代陶瓷基体。
雾化器底座还开设进气孔，进气孔位于烟气通道的下方，且进气孔和烟气通道二者连通，便于外界空气源源不断补充到雾化芯。雾化芯通过电路板连接至电池，雾化芯持续将吸附的雾化液雾化，雾化后的雾化液通过烟气通道流出，进入人的口腔。
目前市场上有两类雾化芯，一类是有棉的雾化芯，一类是无棉的雾化芯，其根本的区别是导液材料是含棉的还是不含棉的。有棉的导液速度快、口感好，但是容易干烧损坏。无棉的雾化芯的导液材料是陶瓷或者硅制纤维绳，能耐干烧，但是导液速度没有棉花的高，口感差。特别是陶瓷雾化芯，其加工工艺是通过高温烧制出来的，其内部含有一定的孔隙率，能够具有一定的导液能力，防止干烧损坏，但是存在如下缺陷。
陶瓷雾化芯工作原理是，陶瓷雾化芯包括陶瓷基体和设置于陶瓷基体表面的发热丝，雾化液通常是在毛细作用下输送至加热体进行雾化，加热体直接将雾化液从室温加热到汽化温度（即雾化温度）。以上进油为例，雾化液从陶瓷基体的上表面进入陶瓷基体，沿着陶瓷分子之间的间隙向下流动，在陶瓷基体的下表面被发热丝加热雾化，雾化后的烟雾被空气带走，进入人的口腔。由于雾化液是配置在储液腔内的，储液腔一般是封闭的，发热丝工作，消耗雾化液，当储液腔内负压超过陶瓷阻力时，空气会从外部通过陶瓷芯向下运动进入到储液杯内，以补充储液杯内的压强，确保雾化液能够释放到陶瓷芯里。
造成进液速度慢的主要原因是，空气通过陶瓷基体回到储液杯时的阻力，阻力越大供液越不好，因为储液杯是密封状态的，雾化芯在工作时消耗雾化液，造成储液杯内负压，负压越大，雾化液越不容易进入到陶瓷芯上，而负压大小取决于陶瓷对空气的阻力，孔隙率大，阻力则小，孔隙率小，则阻力大。孔隙率太大就会漏液，因此很难控制平衡。
此外，陶瓷基体还存在如下问题：由于温差大，会造成炸油，也就是有颗粒雾化液飞溅；时常会出现雾化液无法及时抵达加热体处，导致加热体干烧产生焦味和其它有害物质，进而影响用户体验。
因此有必要设计一种雾化芯，以解决上述问题。
 技术解决方案
本申请旨在至少解决现有技术中存在的技术问题之一。为此，本申请提出一种雾化芯、雾化器和电子雾化装置，外界空气能够通过回气结构回流到雾化器的储液腔内，抵消储液腔内的负压，加速雾化液流入陶瓷基体。

 本发明的实施方式
本申请提供一种雾化芯、雾化器和电子雾化装置，用于外界空气通过回气结构回流到雾化器的储液腔内，抵消储液腔内的负压，加速雾化液流入陶瓷基体。

在本申请的描述中，需要理解的是，涉及到方位描述，例如上、下、前、后等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
本申请的描述中，需要说明的是，除非另有明确的限定，设置、安装、连接等词语应做广义理解，所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本申请中的具体含义。
本申请提供一种雾化芯，包括一陶瓷基体，陶瓷基体具有相对设置的第一面和第二面，第一面和第二面之间设置有回气结构，第一面和第二面之中的至少一面设置有至少一个加热体。
如图1至6所示，本申请提供一种雾化芯，包括陶瓷基体1，陶瓷基体1呈薄片状，其具有相对设置的第一面和第二面，第一面和第二面分别为陶瓷基体1的上端面和下端面，回气结构为贯穿陶瓷基体的上端面和下端面的至少一个通孔2，通孔2内设置有导油棉4。
本实施例中，可以在陶瓷基体1的第二面，即上端面或者下端面设置一加热体，例如可以设置发热丝3。这样，导油棉4可以保证气流的顺利回流，还可以保持并包含雾化液，防止雾化液的外泄。陶瓷基体1可以分为回气区和加热区，通孔2设置于回气区，加热体可以位于加热区，且加热区和回气区不重叠，可参见图4中的虚线，以此为分界线，两边是回气区，中间是发热区。
使用时，可以将陶瓷基体1的下端面设置发热丝3，或者设置丝印电阻，储液腔（未图示）中的雾化液通过陶瓷基体1的上端面向下流动，到达陶瓷基体1的下端面，发热丝3通电，发热丝3加热雾化雾化液，雾化后的雾化液从陶瓷基体1的前后两个侧面向上流动，流入烟嘴供吸食。由于陶瓷基体1开设有通孔2，通孔2可以抵消储液腔内的负压，随着储液腔内雾化液的减少，储液腔的气压减少，需要补充空气以保持储液腔内的气压和外界大气压持平，使储液腔的雾化液继续顺利流入到陶瓷基体1。如果未补充空气进储液腔，储液腔内的雾化液则难以进入陶瓷基体1，导致进液不畅，外界空气持续补入，储液腔内的气压和外界大气压趋于一致，通过这样及时的回气，能够保证供液的速率以及供液的量。
进一步地，外界空气经过通孔2后可以直接进入储液腔或者通过弯折的气路，例如侧向转弯回流到储液腔内。
本申请提供的雾化芯的另一实施例，请参见图5，其包括同轴设置的第一主体11和第二主体12，第一主体11位于第二主体12的上部，第一主体11和第二主体12沿轴向开设一烟气通道，第一主体11的外径小于第二主体12的外径，位于第一主体11内的烟气通道的内壁向外开设通孔2，通孔2贯穿第一主体11的外壁，第一主体的外壁套设一导油棉4。使用时，位于第二主体12内侧的发热丝3将陶瓷主体1吸附的雾化液雾化，位于第一主体11的通孔2可以将外界的空气补充进来，通过导油棉4回流到储液腔，保持储液腔内气压和外界大气压平衡，便于雾化液持续地、顺利地进入陶瓷主体1。
以上对本申请提供的雾化芯中的陶瓷基体上设有通孔的实施例进行详细描述，以下对本申请提供的另一种雾化芯进行具体说明。参考图1至图7描述本申请实施例的雾化芯100。
雾化芯100为雾化器的关键构成部件，雾化器内开设有储液腔和雾化腔（图中未示出），储液腔和雾化腔彼此隔离而不连通，储液腔用于存储以气溶胶生成基质为代表的雾化液，雾化液雾化后形成的烟雾从雾化腔溢出。雾化器还开设有进气通道和吸气通道（图中未示出），进气通道连通外界和雾化腔，吸气通道同样连通外界和雾化腔，外界空气经进气通道进入雾化腔以携带雾化腔中的烟雾，然后烟雾再经吸气通道以被用户吸出。
雾化芯100在工作时，直接把液态或者半液态的雾化液雾化成气凝胶。雾化芯100可采用陶瓷芯，雾化液通过陶瓷芯的微孔被引导至加热体处，加热体将雾化液从室温直接加热到汽化温度，一般是200℃以上，由此造成雾化温度与室温的温差较大。从而产生如下缺陷：由于温差大，会造成炸油，也就是有颗粒雾化液飞溅；由于飞溅的颗粒雾化液比较多，雾化器的冷凝油比较多，会回流到气道内，造成阻塞气道；陶瓷芯的导油速率较低，容易造成干烧。
参照图7-图13所示，本申请的第一方面实施例的雾化芯100，该雾化芯100用于雾化液态或者半液态类雾化液，其包括陶瓷基体103、第一加热体101和第二加热体102，第一加热体101连接于陶瓷基体103，用于加热雾化液至第一温度；第二加热体102用于加热雾化液至第二温度；其中，雾化液能由第一加热体101流向第二加热体102，第一温度低于雾化液的雾化温度，第二温度高于或等于雾化液的雾化温度。
需要说明的是，液态或者半液态类雾化液可以为油状物或者膏状物，液态或者半液态的区别主要在粘度上，雾化液可以为治疗呼吸道及肺部疾病的药品，或者具有镇定作用或提升兴奋性的物品，或者烟油、烟膏等。
还需要说明的是，雾化温度跟雾化液的类型相关，例如对于烟油，其雾化温度通常在220℃到250℃之间，例如雾化温度为220℃、230℃或250℃等。第一温度低于雾化液的雾化温度，第二温度高于或等于雾化液的雾化温度，第一温度的取值范围可以为40℃～180℃，例如预热温度取值为40℃、70℃、120℃或180℃等。由此实现，第一加热体101用于预热雾化液，提高雾化液的温度，第二加热体102用于对雾化液进行雾化，即将雾化液由第一温度加热至第二温度，从而避免了雾化液从室温直接加热到第二温度，减少了雾化液在雾化前后的温差，减少了雾化过程中的炸油几率，即减少了雾化液颗粒飞溅，即避免了冷却后的雾化液颗粒回流到气道内，防止造成阻塞气道。
还需要说明的是，陶瓷基体103可采用多孔陶瓷材料制成，故陶瓷基体103内包含有大量的微孔而具有一定的孔隙率，孔隙率可以定义为物体中孔隙的体积与材料在自然状态下总体积的百分比，该陶瓷基体103的孔隙率较低，例如陶瓷基体103的孔隙率为8％～22％。同时，雾化液在常温下的粘度较大，该粘度的取值范围可以为40mPa.S～1300mPa.S。粘度较大，会导致雾化液不能较快的传导至加热体处。本申请的上述实施例中的雾化芯100中，在雾化器工作时，第一加热体101对雾化液预热，由于液体的粘度与温度成反比，故预热后雾化液的粘度将低于常温下雾化液的粘度，从而减低雾化液流经陶瓷基体103内部的阻力，此时，粘度降低的雾化液将以相对更快的速度在短时间内通过陶瓷基体103内部的微孔抵达至第二加热体102处进行雾化，以避免陶瓷基体103内因单位时间内雾化液的渗入量不够而导致干烧。可以理解的是，第一加热体101可以为膜片状的预热膜，还可以为线条状的预热丝，例如电阻丝，可以采用不锈钢材料、钛金属材料或钛合金材料等制成。根据实际情况的需要，第一加热体101可以通过印刷工艺、喷涂工艺或电镀工艺与陶瓷基体103连接。进一步说明的是，第二加热体102可以为膜片状的加热膜，还可以为线条状的加热丝，例如电阻丝，可以采用不锈钢材料、钛金属材料或钛合金材料等制成。第二加热体102可以直接贴附在陶瓷基体103的端面上，根据实际情况的需要，第二加热体102可以通过印刷工艺、喷涂工艺或电镀工艺与陶瓷基体103连接。
在一些实施例中，当雾化液可以供吸用的物质时，通过设置二级加热体，进行预加热，使雾化液在进入第二加热体102前先加热到一定的温度，该温度可以人为的控制，让雾化液在汽化前发生量变而不不汽化，它的作用有两个，一个是降低温差，另一个是在加热的情况下会把雾化液里面的大分子团催化成小分子团，以提高雾化液的功效，例如雾化液为烟油时，二级加热能使得烟油更充分的挥发香味和尼古丁。由于供油充足，第二加热体102工作时，不会造成局部欠油高温，也同时减少了局部高温时的积碳，因此使用寿命也会延长。
需要说明的是，雾化芯100还包括用于连接电源正极的第一电连接件（图中未示出）和用于连接电源负极的第二电连接件（图中未示出），第一电连接件和第二电连接件分别跟第一加热元件的第一电极201和第二加热元件的第二电极301连接，由此实现了电源对雾化芯100的供电。
参照图7、图10所示，第一加热体101和第二加热体102分别位于陶瓷基体103的相对的两个端面上，例如具体为第一加热体101位于陶瓷基体103的上端面104上、第二加热体102位于陶瓷基体103的下端面105上，由此，使得雾化液能在自身重力的作用以及毛细作用下由第一加热体101流向第二加热体102，便于雾化液的流动。可以理解的是，根据雾化器的具体结构设计，第一加热体101和第二加热体102可分别位于陶瓷基体103的前端面和后端面（图中未示出），或者左端面和右端面（图中未示出）。
参照图7、图9、图10所示，陶瓷基体103整体呈近似方形体结构，其具有上端面104、下端面105以及多个侧面107，其中，第一加热体101位于上端面104，第二加热体102位于下端面105，至少部分上端面104和至少部分下端面105为可渗透区，以使得雾化液能够由上端面104处被预热并进入陶瓷基体103内部，并流动到下端面105处，由第二加热体102加热雾化。为了避免雾化液不必要的从陶瓷基体103中渗出，陶瓷基体103多个侧面107设置为密封层，例如在陶瓷基体103的侧面107设置硅胶涂层。
参照图7、图10所示，陶瓷基体103设置有两个盲孔108，两个盲孔108分别位于第二加热体102的两侧，至少部分盲孔108的底壁302为可渗透区，通过设置盲孔108，能为雾化器的储液腔提供一个回气通道。当雾化液被逐渐消耗时，储液腔的气压降低，当气压降低太多，雾化液将无法顺利流向第二加热体102处，通过设置盲孔108，底壁302为可渗透区，由于盲孔108的底壁302与陶瓷基体103的上端面104之间的距离较小，从而使得气体能够降为方便的透过，以补充到储液腔中，达到回气的效果，图7和图10中两侧竖直箭头即为回气的方向。可以理解的是，跟盲孔108的底壁302相对应的陶瓷基体103的上端面104为可渗透区。需要说明的是，盲孔108至少设置为1个，例如1个，3个或者更多，盲孔108应避开第一加热体101和第二加热体102设置。
参照图10所示，在一些实施例中，盲孔108位于第二加热体102所在的下端面105，并位于第二加热体102的一侧。盲孔108的深度，可以设置为陶瓷基体103厚度的二分之一至五分之四，在避免漏液的同时，达到较好的回气效果。
参照图7所示，陶瓷基体103位于第二加热体102两侧的部位设置为减薄区109，两个盲孔108均设置于减薄区109，通过设置减薄区109，能够节省加工成本。在一些实施例中，减薄区109上设置盲孔108的面设置为弧形面106。第二加热体102将雾化液加热，产生气溶胶，气溶胶被使用者吸出后使用，就在气溶胶吸出过程中产生气流，通过将减薄区109的下侧面107设置为弧形面106，能够使得气流的流动过程更为顺畅，减少气溶胶排出过程中的阻力，也能避免气溶胶过多的黏附在陶瓷基体103的下端面105上，提升使用者的体验性。图1中下部的两斜向箭头即示出了气溶胶的流动方向。需要说明的是，减薄区109的下侧面107也设置为斜面（图中未示出），以此，减小气溶胶的流动阻力。
参照图12所示，在一些实施例中，盲孔108的开口处罩设有透气膜601。通过设置透气膜601，能够在保证气体顺畅进入盲孔108中的同时，避免气溶胶气流进入到盲孔108中，由此减少气流阻力，同时，也能避免气溶胶过多的黏附在盲孔108的侧壁或者底壁302上，堵塞回气通道，另外，当吸出作用较大，气流速度较快，盲孔108的存在容易形成噪音，例如哨音，通过设置透气膜601，能避免上述情况出现。
在一些实施例中，第一加热体101电连接有温度控制元件（图中未示出），由此实现通过进行温控来防止干烧，其原理是，第一加热体101电连接有温度控制元件，如果第二加热体102处缺少雾化液时，第一加热体101的温度上升会很快，因此，来判断是否需要在雾化器的储液腔中是否添加雾化液，或者先做暂停等控制。
参照图13所示，在一些实施例中，第二加热体102设置为第一电阻丝701和第二电阻丝702，第一电阻丝701和第二电阻丝702可根据需要交替工作，另外，第一电阻丝701和第二电阻丝702的连接电路可使得第一电阻丝701或第二电阻丝702单独作用，或者第一电阻丝701和第二电阻丝702并联作用，或者第一电阻丝701和第二电阻丝702串联作用，即实现了单个电阻发热、并联发热、串联发热四种工作模式，供使用者根据需要选择。需要说明的是，第一电阻丝701和第二电阻丝702的电阻可以相同，或者不同，第二加热体102还可以设置为3个以上的电阻丝，以实现更多的工作模式。
本申请的第二方面实施例的雾化器，该雾化器包括本申请第一方面实施例的雾化芯100。根据本申请第二方面实施例的雾化器，当采用上述实施例的雾化芯100，第一加热体101能实现预热作用，以减小雾化液的温度与第二温度之间的温差，减少炸油几率，另外，通过预热作用能降低待导入陶瓷基体103的雾化液的粘度，避免第二加热体102发生干烧。此外，图1至图6所示实施例中的通孔2、以及图7至图13所示实施例中的盲孔108还可以抵消储液腔内的负压，保持储液腔内的气压和外界大气压持平，从而保证雾化液顺利快速、并大量地流入到陶瓷基体中，提升了雾化后的烟雾口感，优化了雾化器的性能。
本申请第三方面实施例的电子雾化装置，请参见图6，包括：电源、控制电路和本申请第二方面实施例的雾化器，其中，电源与雾化器连接，并给雾化器供电，控制电路用于控制第一加热元件和第二加热元件加热。根据本申请第三方面实施例的电子雾化装置，当采用上述实施例的雾化器，能减小雾化液与第二温度之间的温差，减少炸油几率，并能避免第二加热体102发生干烧，提高电子雾化装置的品质。
上面结合附图对本申请实施例作了详细说明，但是本申请不限于上述实施例，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本申请宗旨的前提下作出各种变化在此处键入本发明的实施方式描述段落。
