具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
如图1-图3所示，根据本申请第一方面实施例的雾化装置100，包括外壳1、雾化组件2、换气通道3和第一密封件4。
外壳1内设有储液仓11、气道12以及雾化仓13，所述储油仓11用于储存气溶胶基质，所述气道12与所述雾化仓11连通，外壳1设有与外界连通的进气口14和出气口15，所述进气口14与所述雾化仓11连通，所述出气口15与所述气道12连通。
雾化组件2设于外壳1内，雾化组件2固定于储液仓11和雾化仓13之间，雾化组件2包括支架21和雾化芯23，所述支架具有朝向所述储液仓11的支架顶面211，所述支架顶面211设有第一换气槽2111，所述第一换气槽2111朝向所述储液仓11开设第一槽口21111，所述支架与所述外壳1固定，所述雾化芯23与所述支架21固定，所述雾化芯23用于雾化所述气溶胶基质并朝向所述雾化仓13释放气溶胶，进而可通过气道12将气溶胶及空气的混合气体传输至所述出气口15，供用户吸食。
换气通道3包括第一道段31和第二道段32，所述第一道段31形成于所述第一换气槽2111内，所述第二道段32分别与所述第一道段31、雾化仓11连通，使得所述雾化仓11 内的气体可通过换气通道3进入所述储液仓11。应当理解的是，第二道段32是连通第一道段31、雾化仓11的空间，本申请不限定具体形成所述第二道段32的形式，可以通过管件形成、或者槽和壁围合形成，也可以是多种形式形成的多段空间连通形成的。
第一密封件4包括第一密封部41和弹性密封部43。所述第一密封部41设置于所述雾化组件2与所述外壳1之间，以沿着支架21的周向形成密封，防止所述储液仓11内的气溶胶基质通过支架21与外壳1之间的缝隙泄漏到所述雾化仓13内。所述弹性密封部43封盖所述第一槽口21111，所述弹性密封部43由弹性材料制成，例如硅胶，其可在外力作用下发生弹性形变，所述弹性密封部43构造成在所述第一道段31与所述储液仓11之间的压差大于预定值时开启所述第一槽口21111，使得所述第一道段31与所述储液仓11连通。应当理解的是，“所述第一道段31与所述储液仓11之间的压差”指的是，所述第一道段31内的压强大于所述储液仓11内的压强，所述第一道段31与所述储液仓11之间的压差等于所述第一道段31内的压强减去所述储液仓11的压强。
雾化装置100在使用时，雾化芯23吸收、雾化所述气溶胶基质，随着储液仓11内的气溶胶基质逐渐被消耗，所述储液仓11内的气压逐渐减小，若不能补充所述储液仓11的气压，雾化仓13与所述储液仓11之间的压差越来越大，所述雾化芯23吸液量减少，将影响产生气溶胶的效率，对所述雾化装置100的使用造成实质影响。在本实施例中，所述雾化仓13通过所述进气口14与外界连通，所述第一道段31通过所述第二道段32与所述雾化仓13连通，使得第一道段31内的压强维持在稳定的大气压强，随着所述储液仓11内的压强的减小，当所述第一道段31与所述储液仓11内的压差达到预定值时，在压力的作用下所述弹性密封部产生弹性形变，使得所述第一槽口21111与所述储液仓11连通，所述雾化仓13内的气体可通过所述换气通道3进入所述储液仓11内，直至所述压差小于所述预定值，所述弹性密封部43恢复封盖所述第一槽口21111。应当理解的是，所述预定值可根据需求通过更改所述弹性密封部43的结构和材料来设定，在本实施例中，所述预定值大于零。
在本实施例中，通过在所述支架顶面211上设置第一换气槽2111，相较于仅在支架21的侧面设置换气槽，所述支架顶面211上的第一换气槽2111能够增加进气面积(第一槽口21111的面积)，使得在相同压差下，所述弹性密封部43受到更大的力，更易于开启换气。
第一换气槽2111具有槽底壁21112、槽顶面21113以及二者之间的槽侧壁21114，所述槽侧壁21114至少部分凸出于所述支架顶面211形成凸筋2113，所述凸筋2113用于与所述弹性密封部43抵接，当所述弹性密封部43封盖所述第一槽口21111时，所述凸筋2113与所述弹性密封部43抵接。
槽侧壁21114凸出支架顶面211形成凸筋2113，则凸筋2113的远离所述支架顶面211的端面形成所述槽顶面21113，即槽顶面21113与支架顶面211不共面，二者形成台阶面， 当所述弹性密封部43封盖所述第一槽口21111时，所述弹性密封部43与支架顶面211之间形成缝隙，减小了所述弹性密封部43与所述支架21的接触面积，使得所述弹性密封部43更容易开启。
所述槽顶面21113的宽度为0.2mm-0.5mm，优选为0.2mm，使得所述支架21与所述弹性密封部43具有较小的接触面积，容易开启。
所述第一换气槽2111的深度大于所述台阶面的高度，即所述槽顶面21113与所述槽底壁21112之间的距离大于所述槽顶面21113与所述支架顶面211之间的距离，能增加所述第一换气槽2111的通气量，提升换气效率。所述槽顶面21113与所述槽底壁21112之间的距离为所述槽顶面21113与所述支架顶面211之间的距离的3-5倍。
在本实施例中，所述第一换气槽2111的深度为0.1mm-0.3mm。
在一实施例中，所述第一换气槽2111具有位于所述支架21边缘的开放端(未标号)，所述第一道段31通过所述开放端与所述第二道段32连通。
在一实施例中，第一密封部41包覆支架21的外表面的至少一部分，第一密封部41与支架21之间限定出第二道段32，所述第二道段32从所述支架21的侧面连通至所述雾化仓13。
应当理解的是，第二道段32直接从侧边连通至雾化仓13仅作为本申请的一种实施方式，“第二道段32与雾化仓13连通”包括第二道段32与雾化仓13间接连通，在所示实施例中，支架21上形成有彼此分隔开的安装腔213和换气腔215，雾化组件2固定安装在安装腔213内，第二道段32与换气腔215连通，换气腔215与雾化仓13连通，使得第二道段32与雾化仓215通过所述换气腔215间接连通。
例如，储液仓11和雾化仓13可以沿外壳1的第一方向X1排布，雾化组件2位于储液仓11和雾化仓13之间，且雾化仓13的安装腔213分别与储液仓11和雾化仓13连通。出气口15可以设在外壳1的顶部且与气道12连通，进气口14可以设在外壳1的底部且与雾化仓13连通。安装腔213和换气腔215可以沿支架21的第二方向X2彼此间隔开，第二方向X2与第一方向X1垂直，安装腔213的形状与雾化组件2的形状相适配，以将雾化组件2牢靠地安装在支架21上。支架21可以通过第一密封部41与外壳1的内壁面形成过盈配合。
当雾化装置100工作时，储液仓11内的气溶胶基质经雾化组件2移动到雾化仓13内时，储液仓11内会处于一种负压状态，当压差达到预定值时，雾化仓13内的气体流向换气腔215并通过第二道段32、第一道段31流动到储液仓11内，以使储液仓11的压力和雾化仓13的压力维持平衡，从而储液仓11内的气溶胶基质能够持续地渗透至雾化组件2，使得雾化组件2能够获取足够的气溶胶基质以保持气溶胶的生成效果。
如图3所示，弹性密封部43由所述第一密封部41沿第二方向X2延伸，所述弹性密封 部43至少部分沿所述第二方向X2凸出所述凸筋2113。
下面举例描述，当雾化装置100应用于电子烟时的工作过程。
雾化装置100与供电组件结合后，用户通过对出气口15吸气，此时供电组件中的气动传感器(例如咪头)感应，使得供电组件中的电源与雾化组件2启动电连接，雾化组件2工作例如雾化组件2进行加热，储液仓11内的气溶胶基质例如烟油被雾化组件2吸收并被雾化组件2加热，在雾化仓13内形成气溶胶，同时外界空气经进气口14进入雾化仓13内并与雾化仓13内的气溶胶进行混合，混合后的烟雾经气道12和出气口15被用户吸入，实现用户的使用需求。用户停止从出气口15吸气时，储液仓11内的气溶胶基质例如烟油会停止从储液仓11进入到雾化组件2内，以避免储液仓11内的气溶胶基质无效的消耗，提高了气溶胶基质的利用率。其中，这里需要解释的是，一些电子烟将雾化装置100和供电组件设置成分体结构，两者可拆卸地结合，也有一些电子烟将雾化装置100与供电组件设置成不可拆卸的结构，这里不做具体限定。
根据本申请实施例的雾化装置100，通过使支架21上形成有彼此分隔开的安装腔213和换气腔215，雾化组件2固定安装在安装腔213内，换气腔215与雾化仓13连通，且第一密封部41与支架21之间限定出的第二道段32的一端与换气腔215内部连通，第二道段32的另一端与第一道段31连通。由此，在雾化装置100工作时，可以通过换气通道3调节储液仓11和雾化仓13之间的压差，保证储液仓11的压力和雾化仓13的压力维持平衡，从而储液仓11内的气溶胶基质能够持续地通过雾化组件2移动至雾化组件2内，使得雾化组件2能够获取足够的气溶胶基质以保持烟雾的生成效果，同时可以降低用户抽吸时的阻力，提升用户的体验。
在所示实施例中，换气腔215贯穿支架21的第一方向X1的一侧表面。由此，实现了换气腔215与雾化仓13的连通，当雾化仓13与储液仓11的压差达到预定值时，雾化仓13内的气流可以经换气腔215、第二道段32流向第一道段31并推动弹性密封部43发生弹性形变，以使雾化仓13内的气流流向储液仓11，进而可以有效地保证储液仓11的压力和雾化仓13的压力维持平衡。
根据本申请的一些实施例，雾化组件2包括第二密封件5，雾化芯23包括多孔体和发热体，第二密封件5套设于多孔体的外缘，其中多孔体具有靠近储液仓11的吸液面和靠近雾化仓的雾化面，发热体设于雾化面。其中，吸液面至雾化面的延伸方向为第一方向X1。
应当理解的是，单独设置第二密封件5仅作为本申请的一种实施方式，在其他实施例中，可以没有第二密封件5，通过第一密封件4上一体成型第二密封部(未示出)，所述第二密封部42设置于所述支架21与所述雾化芯23之间。一方面，沿着雾化芯23的周向形成密封，防止所述储液仓11内的气溶胶基质通过支架21与雾化芯23之间的缝隙泄漏到所述雾 化仓13内；另一方面，雾化芯23可以通过第二密封部42与支架21的内壁面形成过盈配合。
根据本申请的一些实施例，支架21的外周面上形成有换气孔2171和第二换气槽2173，换气孔2171贯穿支架21的外周壁且与换气腔215内部连通，第二换气槽2173具有第二槽口21731，所述第一密封部41封盖所述第二槽口21731，以在第二换气槽2173和第一密封部41之间共同限定出第二道段32，第二换气槽2173的一端与换气孔2171相连，第二换气槽2173的另一端贯穿支架21的第一方向X1的另一侧表面而与第一换气槽2111的开放端连通，换弹性密封部43常封堵第二换气槽2173的上述另一端以及第一换气槽2111的第一槽口21111。当雾化仓13与储液仓11的压差达到预定值时，雾化仓13内的气流可以流向换气腔215，换气腔215内的气流可以经换气孔2171、第二道段32流向第一道段31，并推动弹性密封部43发生弹性形变，以使雾化仓13内的气流流向储液仓11，达到调节储液仓11和雾化仓13之间压差的目的。
在一些可选的实施例中，第二换气槽2173的长度大于换气孔2171与第一换气槽2111之间的距离。例如，换气孔2171形成在支架21的第三方向(未示出)的一侧，所述第三方向与所述第一方向X1、第二方向X2均垂直，第二换气槽2173的一部分延伸至支架21的所述第三方向的另一侧，且所述第一换气槽2111位于支架21的所述第一方向X1的一端。此时第二换气槽2173的形状为折线形，增加了第二换气槽2173的长度，由此，当第二道段32打开时，第二换气槽2173内可以存放少量的气溶胶基质，避免气溶胶基质直接流向雾化仓13内，从而可以避免用户吸入气溶胶基质，保证了用户体验。
在一些可选的实施例中，第二换气槽2173的横截面积处处相等。如此设置，可以保证气流能够顺畅地在第二换气槽2173内流动，从而当雾化仓13与储液仓11的压差大于预定值时，第二换气槽2173内的气流能够快速推动弹性密封部43，进而可以快速调节储液仓11和雾化仓13的压力。
在一些可选的实施例中，第二换气槽2173与换气孔2171的连接位置相对于换气孔2171远离储液仓11。如此设置，当储液仓11中的烟油流入第二换气槽2173，并通过换气孔2171进入雾化仓13中时，由于换气孔2171的位置较高，更靠近储液仓11，因此烟油从第二换气槽2173进入换气孔2171为从“低处”进入“高处”，可以防止储液仓11内的气溶胶基质经第二换气槽2173和换气孔2171流向雾化仓13内，从而可以避免用户抽吸时吸入气溶胶基质。
在所示实施例中，外壳1包括壳体101和底座102，壳体101和底座102配合形成内部空间，雾化组件2设置于所述内部空间内，并分隔出沿第一方向X1分布的储油仓11和雾化仓13，底座102上设有导电钉103，所述导电钉103穿过所述底座以伸入所述内部空间， 并与发热件导电连接。当雾化装置100与供电装置结合后，供电装置可通过所述导电钉103向所述发热件供电以雾化多孔体中的气溶胶基质。
根据本申请第二方面实施例的电子烟(图未示出)，包括供电装置和根据本申请上述第一方面实施例的雾化装置100，所述供电装置用于向所述雾化装置100提供电能。
根据本申请实施例的电子烟，通过采用上述雾化装置100，可以时刻平衡储液仓11和雾化仓13的压力，从而可以减小用户抽吸时的阻力，提升了用户体验。
