Description

一种雾化装置 【技术领域】
本申请涉及雾化设备技术领域，特别是涉及一种雾化装置。
【背景技术】
目前，诸如电子烟等雾化装置，其内雾化腔的腔壁通常是塑胶材质。当雾化腔内温度过高时，往往会导致雾化腔的腔壁发生变形，甚至烤焦等稳定性问题。并且，当雾化装置加热雾化诸如烟油等气溶胶基质时，容易因为气溶胶基质分布不均以及局部温度过高而发生炸油现象，未经雾化的气溶胶基质飞溅至雾化腔腔壁，或是雾化的气溶胶基质在雾化腔腔壁冷凝，而雾化腔腔壁上附着的气溶胶基质容易沿腔壁到达雾化装置底部而引发漏液的问题。
【申请内容】
有鉴于此，本申请主要解决的技术问题是提供一种雾化装置，能够提高雾化装置的结构稳定性以及改善雾化装置的防漏液效果。
为解决上述技术问题，本申请采用的一个技术方案是：提供一种雾化装置。该雾化装置包括进气口、出气口以及雾化腔。雾化腔分别连通进气口和出气口，并且雾化腔内设有雾化组件，雾化腔内壁靠近雾化组件的部分设有第一毛细吸液结构，其中在第一毛细吸液结构吸收气溶胶基质后能够随气溶胶基质的吸热雾化而降低第一毛细吸液结构所在位置处的雾化腔腔壁的温度。

在本申请的一实施例中，第一毛细吸液结构包括第一毛细槽和第二毛细槽，第一毛细槽设于雾化腔内壁连接出气通道内壁的部分，第二毛细槽相对第一毛细槽远离出气通道且第二毛细槽与第一毛细槽之间具有间隙，其中第一毛细槽中的气溶胶基质在间隙汇流后进入第二毛细槽。
在本申请的一实施例中，第一毛细槽和第二毛细槽的宽度小于1mm。
在本申请的一实施例中，第一毛细槽和第二毛细槽沿靠近出气通道的方向延伸。

【具体实施方式】
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请的实施例，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
为解决现有技术中雾化装置的结构稳定性以及防漏液效果较差的技术问 题，本申请的一实施例提供一种雾化装置。该雾化装置包括进气口、出气口以及雾化腔。雾化腔分别连通进气口和出气口，并且雾化腔内设有雾化组件，雾化腔内壁靠近雾化组件的部分设有第一毛细吸液结构，其中在第一毛细吸液结构吸收气溶胶基质后能够随气溶胶基质的吸热雾化而降低第一毛细吸液结构所在位置处的雾化腔腔壁的温度。以下进行详细阐述。
请参阅图1和图2，图1是本申请雾化装置一实施例的结构示意图，图2是图1所示雾化装置A-A方向的剖面结构示意图。
在一实施例中，雾化装置10可以是诸如电子烟等形式。当然，也可以是应用于医疗领域的医疗雾化设备等。下文以电子烟形式的雾化装置10为例进行阐述，并非因此造成限定。
具体地，雾化装置10包括进气口11、出气口12以及雾化腔13。雾化腔13分别连通进气口11和出气口12，并且雾化腔13内设有雾化组件14，其中雾化组件14用于雾化雾化装置10内的气溶胶基质(例如烟油、药液等)。
进气口11所在位置处为雾化装置10进气的位置。当用户抽吸时，外部的气体自进气口11进入雾化腔13，以将雾化腔13内经雾化组件14雾化的气溶胶基质携带至出气口12并输出至用户，以供用户吸食。
可选地，雾化组件14可以是多孔发热体，其通过毛细作用力吸收气溶胶基质并产热以雾化气溶胶基质。优选地，雾化组件14可以是多孔陶瓷发热体等，其还可以进一步设置发热膜。当然，在本申请的其它实施例中，雾化组件14还可以是纤维棉和发热丝搭配的设计，在此不做限定。
考虑到当雾化腔13内温度过高时，往往会导致雾化腔13的腔壁发生变形，甚至烤焦等稳定性问题，本实施例的雾化腔13内壁靠近雾化组件14的部分设有第一毛细吸液结构15。第一毛细吸液结构15用于吸收由于炸油而飞溅至雾化腔13腔壁的气溶胶基质以及在雾化腔13腔壁冷凝的气溶胶基质等。
由于气溶胶基质雾化需要吸热，并且第一毛细吸液结构15所在位置处具有较高温度，因此被第一毛细吸液结构15吸收的气溶胶基质能够在第一毛细吸液结构15中继续雾化。如此一来，在第一毛细吸液结构15吸收气溶胶基质后，由于第一毛细吸液结构15中的气溶胶基质继续雾化，至少部分热量被气溶胶基质吸收，使得雾化组件14传递至第一毛细吸液结构15所在位置处的雾化腔13腔壁的热量减少以及使得第一毛细吸液结构15所在位置处的雾化腔13腔壁的热量被气溶胶基质吸收，进而降低第一毛细吸液结构15所在位置处的雾化腔13 腔壁的温度，即随气溶胶基质的吸热雾化而降低第一毛细吸液结构15所在位置处的雾化腔13腔壁的温度，能够避免雾化腔13腔壁由于温度过高而发生变形、烤焦等稳定性问题，进而能够提高雾化装置10的结构稳定性。
当然，第一毛细吸液结构15中的气溶胶基质继续雾化，也意味着第一毛细吸液结构15吸收的气溶胶基质被重新利用，能够提高雾化装置10的气溶胶基质的利用率。
可选地，在一优选实施例中，当雾化组件14发热时，雾化腔13腔壁的温度小于或等于150℃。可以看出，通过本实施例第一毛细吸液结构15的设计，能够控制雾化腔13腔壁的温度处于150℃以下，进而有效避免雾化腔13腔壁由于温度过高而发生变形、烤焦等稳定性问题。
进一步地，本实施例的第一毛细吸液结构15设于雾化腔13内壁靠近雾化组件14的部分，即第一毛细吸液结构15靠近雾化组件14设置，能够进一步降低雾化腔13腔壁发生稳定性问题的风险，从而进一步提高雾化装置10的结构稳定性。
并且，本实施例的第一毛细吸液结构15具有吸收、存储气溶胶基质的作用。雾化腔13腔壁上至少部分的气溶胶基质能够锁止于第一毛细吸液结构15中，从而能够减少雾化装置10内积累的气溶胶基质，进而能够降低雾化装置10漏液的风险，有利于改善雾化装置10的防漏液效果。举例而言，对于直液式的雾化装置10而言，雾化装置10的底部往往积累较多的气溶胶基质，因而本实施例的第一毛细吸液结构15能够有效减少雾化装置10底部所积累的气溶胶基质，进而降低雾化装置10漏液的风险，改善雾化装置10的防漏液效果。
需要说明的是，当用户刚刚开始抽吸时，雾化组件14内气溶胶基质还未分布均匀，并且雾化组件14还未受热均匀，即存在局部过热的情况，因此此时最容易发生炸油现象。由于此时雾化组件14温度较低，因炸油而飞溅的气溶胶基质的温度同样较低，飞溅的气溶胶基质被第一毛细吸液结构15吸收由于温度较低并不会影响第一毛细吸液结构15所在位置处的雾化腔13腔壁的结构稳定，反而能够在第一毛细吸液结构15处形成保护膜，以随第一毛细吸液结构15中气溶胶基质的吸热雾化而降低第一毛细吸液结构15所在位置处的雾化腔13腔壁的温度，进而避免雾化腔13腔壁由于温度过高而发生变形、烤焦等稳定性问题。
请参阅图2至图4，图3是本申请雾化装置的雾化组件、第一承载件以及第 二承载件一实施例的结构示意图，图4是图3所示雾化组件、第一承载件以及第二承载件的爆炸结构示意图。
在一实施例中，雾化装置10还包括第一承载件16和第二承载件17，第一承载件16和第二承载件17对接形成雾化腔13，进气口11设于第一承载件16，雾化组件14设于第二承载件17，并且第一毛细吸液结构15设于第二承载件17的内壁。其中，第一毛细吸液结构15可以设于第二承载件17的侧壁或者底壁，图2展示了第一毛细吸液结构15设于第二承载件17的侧壁的情况，在此不做限定。
请参阅图2和图5，图5是图3所示雾化组件、第一承载件以及第二承载件的俯视结构示意图。
在一实施例中，当雾化组件14发热至其最高温度达到250℃时，如若雾化腔13腔壁未设置第一毛细吸液结构15，则通常需要雾化组件14表面与雾化腔13内壁之间的距离达到2mm以上才能保证雾化腔13腔壁不过热变形、烤焦等，这就使得雾化腔13横截面的面积过大而致使用户抽吸时雾化腔13内气流流速过低，不利于气流携带雾化的气溶胶基质供用户吸食。
有鉴于此，本实施例的雾化腔13腔壁在设置第一毛细吸液结构15后，允许雾化组件14表面与雾化腔13内壁之间的距离(如图5所示的距离W)降低至0.5mm-1.8mm，进而控制雾化腔13腔壁的温度处于150℃以下。相较于未设置第一毛细吸液结构15的情况，本实施例雾化组件14表面与雾化腔13内壁之间的距离降低，使得雾化腔13横截面的面积减小而用户抽吸时雾化腔13内气流流速提高，具体地在用户抽吸时雾化腔13内气流流速至少提高10％，并且还能够保证雾化腔13腔壁不过热变形、烤焦等。此外，本实施例雾化组件14表面与雾化腔13内壁之间的距离降低，意味着允许雾化腔13设计更小的体积，有利于雾化装置10的微型化。
优选地，在本实施例的雾化腔13腔壁设有第一毛细吸液结构15的情况下，雾化组件14表面与雾化腔13内壁之间的距离优选为1mm-1.5mm，如此能够尽可能提高雾化腔13内气流流速，同时尽可能保证雾化腔13腔壁不过热变形、烤焦等。
请继续参阅图2。在一实施例中，雾化装置10还包括出气通道18。出气通道18分别连通出气口12和雾化腔13。自进气口11进入雾化腔13的气体，将经雾化组件14雾化的气溶胶基质携带至出气通道18，并沿出气通道18输出至 用户，以供用户吸食。
由于雾化的气溶胶基质接触出气通道18内壁后会发生冷凝现象，出气通道18内壁上冷凝的气溶胶基质会沿出气通道18重新回到雾化腔13，因此本实施例雾化腔13内壁连接出气通道18内壁的部分设有第一毛细吸液结构15，用于吸收沿出气通道18内壁回流的气溶胶基质，如此以重新利用冷凝于出气通道18内壁的气溶胶基质以及用于在第一毛细吸液结构15处形成保护膜以控制雾化腔13腔壁的温度(即上述实施例所阐述随第一毛细吸液结构15中的气溶胶基质的吸热雾化而降低第一毛细吸液结构15所在位置处的雾化腔13腔壁的温度)。
进一步地，为引导出气通道18内壁上冷凝的气溶胶基质回流至雾化腔13，本实施例的出气通道18的内壁设有延伸至雾化腔13的第二毛细吸液结构181，第二毛细吸液结构181吸收出气通道18内壁上冷凝的气溶胶基质后，将其所吸收气溶胶基质引导至雾化腔13，有利于优化出气通道18内壁上气溶胶基质的导流效果。
更进一步地，部分第二毛细吸液结构181与设于雾化腔13内壁连接出气通道18内壁的部分的第一毛细吸液结构15连通，该部分第二毛细吸液结构181中的气溶胶基质引导至第一毛细吸液结构15中，以助于第一毛细吸液结构15中气溶胶基质的积累，进而用于提高雾化装置10的结构稳定性。
而剩余部分的第二毛细吸液结构181与设于雾化腔13内壁连接出气通道18内壁的部分的第一毛细吸液结构15间隔设置，即剩余部分的第二毛细吸液结构181与第一毛细吸液结构15不连通，该部分第二毛细吸液结构181中的气溶胶基质可以直接引导至雾化组件14，以重新经雾化组件14雾化。
请继续参阅图2。在一实施例中，雾化腔13连通出气通道18的部分设有渐缩通道131。渐缩通道131的横截面面积沿靠近出气通道18的方向(如图2中箭头X所示，下同)逐渐减小，上述设于雾化腔13内壁连接出气通道18内壁的部分的第一毛细吸液结构15至少部分位于渐缩通道131的内壁。
当发生明显的炸油现象时，向靠近出气通道18方向竖直飞溅的大液滴气溶胶基质会在重力的作用下重新回到雾化组件14而重新被加热雾化，而向四周飞溅的大液滴气溶胶基质一部分被侧面的第一毛细吸液结构15吸收，还有一部分气溶胶基质向靠近出气通道18的方向倾斜向上飞溅，其具有竖直向上的分速度，会受到渐缩通道131内壁的阻挡而被渐缩通道131内壁上的第一毛细吸液结构15吸收，而小液滴气溶胶基质在气流的带动下能够进入出气通道18，不会受到 渐缩通道131的影响。如此一来，能够避免大液滴的气溶胶基质进入出气通道18而被用户吸食，影响用户的口感。
并且，当用户抽吸时，气流流经渐缩通道131，由于渐缩通道131的横截面面积沿靠近出气通道18的方向逐渐减小，因此渐缩通道131中气流的流速增大，有利于气流携带雾化的气溶胶基质输出至用户，并且还能够缓解雾化的气溶胶基质冷凝的情况。
请参阅图6，图6是图2所示雾化装置省去雾化组件后的结构示意图。
需要说明的是，第一毛细吸液结构15可以是具有毛细作用力的毛细槽等，能够利用毛细作用力吸收气溶胶基质。当然，第一毛细吸液结构15也可以是其它具有毛细作用力的结构，例如雾化腔13表面进行研磨等粗糙化处理，以形成磨砂面、纹路等形式的具有毛细作用力的结构，即第一毛细吸液结构15。下文以第一毛细吸液结构15采用毛细槽为例进行阐述，并非因此对第一毛细吸液结构15的类型造成限定。
在一实施例中，第一毛细吸液结构15包括第一毛细槽151和第二毛细槽152。第一毛细槽151设于雾化腔13内壁连接出气通道18内壁的部分，而第二毛细槽152相对第一毛细槽151远离出气通道18。其中，第一毛细槽151和第二毛细槽152之间具有间隙19，第一毛细槽151中的气溶胶基质在间隙19汇流后进入第二毛细槽152。如此一来，允许第一毛细槽151中的气溶胶基质在间隙19处混合均匀并均匀分配至第二毛细槽152中，进而改善雾化腔13内壁的第一毛细吸液结构15中气溶胶基质分布的均匀性，有利于降低雾化腔13腔壁发生结构稳定性问题的风险。
进一步地，第一毛细槽151和第二毛细槽152的宽度优选为小于1mm，以使得第一毛细槽151和第二毛细槽152具有足够的毛细吸液能力。如若第一毛细槽151和第二毛细槽152的宽度过大，就会导致第一毛细槽151和第二毛细槽152的毛细吸液能力减弱，不足以满足使用。并且，第一毛细槽151和第二毛细槽152二者宽度的设计值还取决于气溶胶基质的粘度以及雾化装置10的结构设计限制。此外，毛细槽的深度越大，其储液量就越大，因此在结构允许的情况下，增大毛细槽的深度有利于增大第一毛细槽151和第二毛细槽152的储液量，进而有利于降低漏液的风险。
并且，第一毛细槽151和第二毛细槽152均可以沿靠近出气通道18的方向延伸，即沿靠近出气口12的方向延伸，如图6中箭头X所示。进一步地，第一 毛细槽151和第二毛细槽152为竖槽，有利于第一毛细槽151和第二毛细槽152的注塑成型。当然，在本申请的其它实施例中，第一毛细槽151和第二毛细槽152也可以不是竖槽，例如通过3D打印技术等实现。
综上所述，本申请所提供的雾化装置，其雾化腔内壁靠近雾化组件的部分设有第一毛细吸液结构。其中，第一毛细吸液结构用于吸收气溶胶基质并能够在吸收气溶胶基质后能够随气溶胶基质的吸热雾化而降低第一毛细吸液结构所在位置处的雾化腔腔壁的温度，从而避免雾化腔腔壁由于温度过高而发生变形、烤焦等稳定性问题，因而能够提高雾化装置的结构稳定性。
并且，本申请的第一毛细吸液结构具有吸收、存储气溶胶基质的作用，雾化腔腔壁上至少部分的气溶胶基质锁止于第一毛细吸液结构中，能够减少雾化装置内积累的气溶胶基质，进而能够降低雾化装置漏液的风险，有利于改善雾化装置的防漏液效果。
此外，在本申请中，除非另有明确的规定和限定，术语“相连”、“连接”、“层叠”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
