图1-2示出了本发明一些实施例中的电子雾化装置100，该电子雾化装置100可用于雾化液态基质以生成气溶胶，该气溶胶可供用户吸食或者吸入，其在本实施例中可大致呈圆柱状。可以理解地，在其他实施例中，该电子雾化装置100也可呈椭圆柱状、扁平柱状或方形柱状等其他形状。该液态基质可以包括烟油或药液等。
该电子雾化装置100可包括外壳10以及收容于外壳10中的控制模块20、电源30、气源40、喷嘴雾化组件60和储液组件70。气源40用于为喷嘴雾化组件60提供高速气流，其通常可以为气泵。控制模块20与气源40电连接，用于接收指令，该指令可由用户触发或者在电子雾化装置100满足一定条件后自动触发，控制模块20再根据该指令控制气源40的工作。电源30分别与控制模块20、气源40电连接，用于向控制模块20、气源40提供电能。
储液组件70内形成有用于存储液态基质的储液腔71，喷嘴雾化组件60内形成有供液通道61和气流通道62，供液通道61、气流通道62分别与储液腔71、气源40相连通，从供液通道61进入到气流通道62的液态基质能够受气流通道62中流通的高速气流作用而雾化，形成细小的液体颗粒。
喷嘴雾化组件60可至少部分收容于储液组件70中，其可包括喷嘴63。供液通道61、气流通道62均形成于喷嘴63内。具体地，在本实施例中，喷嘴63大致具有圆柱状外形，其可采用塑胶等硬质材料制成。气流通道62沿纵向贯穿喷嘴63并可与喷嘴63同轴设置。供液通道61由喷嘴63的一侧侧面沿横向向内延伸至与气流通道62相连通，且供液通道61的延伸方向与气流通道62的延伸方向垂直。可以理解地，在其他实施例中，喷嘴63的外形也可呈椭圆形或方形等其他形状。
如图3所示，气流通道62可包括供气通道621和雾化腔622。雾化腔622通过供气通道621与气源40连通，并通过供液通道61与储液腔71相连通。雾化腔622靠近供气通道621的一端端面形成雾化面6221，雾化面6221上还形成有雾化口6220。来自供气通道621的高速气流经由雾化口6220喷出到雾化腔622内并在雾化腔622中高速流动，高速气流由伯努利方程在供液通道61内产生负压，此负压传导至储液腔71将储液腔71内的液态基质吸出至雾化腔622，在雾化面6221上形成液膜。随着供液过程的持续进行，液膜运动到雾化口6220的孔壁边缘与高速气流相遇，被高速气流切割雾化成细小的液体颗粒，该液体颗粒再被气流带离雾化口6220，之后随气流喷出完成雾化过程。该液态基质在雾化腔622内的雾化方式为非相变的雾化方式，雾化腔622雾化后形成的液体颗粒的粒径分布可达到SMD=30μm范围内。其中，SMD=液体颗粒总体积/液体颗粒总表面积，表示了液体颗粒的平均粒径。
雾化腔622为直柱状通道，其孔壁面与雾化面6221垂直。在本实施例中，雾化腔622为直圆柱形通道，雾化面6221为同心圆环状，雾化面6221的内壁面界定出雾化口6220。在其他实施例中，雾化腔622、雾化面6221或雾化口6220的横截面也可以是椭圆形或矩形等其他非圆形状。
雾化口6220、雾化腔622的尺寸和形状等参数能够影响雾化腔622内负压的大小以及生成的液体颗粒的粒径大小，并可使流量更稳定。在一些实施例中，雾化口6220的孔径、雾化腔622的孔径、雾化腔622的长度可根据需要设置合适的尺寸。
具体地，雾化口6220的孔径与从雾化口6220出来的气流速度（m/s）相关，其能够影响生成的液体颗粒的粒径大小。在一些实施例中，雾化口6220的孔径范围可以为0.2mm~0.4mm ，优选为0.22mm~0.35mm。
雾化腔622的孔径会影响雾化腔622中的气流流速大小，从而影响雾化腔622及供液通道61内的负压大小。该负压可使液态基质从供液通道61吸至雾化腔622。在一些实施例中，雾化腔622的孔径范围可以为0.7mm~1.3mm。雾化腔622的轴向长度可以为0.8mm~3.0mm。可以理解地，在其他实施例中，雾化口6220或雾化腔622也可具有非圆横截面；当雾化口6220或雾化腔622具有非圆横截面时，雾化口6220的孔径或雾化腔622的孔径分别为其当量直径。术语“当量直径”是指，把水力半径相等的圆孔的直径定义为非圆孔的当量直径。
进一步地，在一些实施例中，雾化口6220的孔径范围为0.22mm~0.35mm，雾化腔622的轴向长度范围为1.5mm~3.0mm，雾化腔622的孔径范围为0.7mm~1.3mm，该取值范围能够使喷嘴雾化组件60在制造工艺上得到优势。
供液通道61与雾化腔622相连通的一端具有一供液口610，该供液口610的中心与雾化面6221之间的垂直距离是保证液膜形成的关键。在一些实施例中，供液口610与雾化面6221之间的垂直距离的范围可以为0.3mm~0.8mm，优选为0.35mm~0.6mm。
进一步地，气流通道62还包括扩张通道623，该扩张通道623与雾化腔622远离供气通道621的一端连通，用于将雾化腔622内雾化后生成的液体颗粒以射流的形式扩散喷出，增大液体颗粒的喷射面积。扩张通道623的横截面积由靠近雾化腔622的一端到远离雾化腔622的一端逐渐增大。具体地，在本实施例中，扩张通道623为沿纵向延伸且孔径由下往上逐渐增大的圆锥形通道。扩张通道623的雾化角（即扩张通道623的扩张角）须具有合适范围，以保证喷射出的液体颗粒具有合适的喷射范围。在一些实施例中，扩张通道623的雾化角可以为30 0~70 0。进一步地，扩张通道623与雾化腔622之间还可采用流线型平滑连接，例如通过倒圆角的方式相切。在其他实施例中，扩张通道623也可以为椭圆锥形状或金字塔形状等其他形状。
供气通道621在一些实施例中可包括收缩通道6211，该收缩通道6211呈收缩形状，其横截面积从远离雾化腔622的一端到靠近雾化腔622的一端逐渐减小，从而能够将来自气源40的气流加速后喷出至雾化腔622。在本实施例中，收缩通道6211为沿纵向延伸且孔径由下往上逐渐减小的圆锥形通道，收缩通道6211的上端孔径小于雾化腔622的孔径，使得收缩通道6211和雾化腔622的交接处形成圆环形的雾化面6221。可以理解地，在其他实施例中，收缩通道6211也可以为椭圆锥形状或金字塔形状等其他收缩形状。
进一步地，供气通道621还包括与收缩通道6211连通的连通通道6212，收缩通道6211通过连通通道6212与气源40连接。连通通道6212可以为沿纵向延伸的直圆柱形通道，连通通道6212的上端与收缩通道6211相连通，连通通道6212的孔径与收缩通道6211的下端孔径一致。在其他实施例中，连通通道6212的横截面也可以是椭圆形或矩形等其他非圆形状。可以理解地，在其他实施例中，喷嘴雾化组件60内形成的供气通道621也可仅包括收缩通道6211；或者，当气流流速足够时，供气通道621也可仅包括连通通道6212。
供液通道61为沿横向延伸的直线形通道，其可以为毛细通道。在气源40停止工作、使得由高速气流在供液通道61内产生的负压消失时，能够利用供液通道61内的毛细力来减少或避免供液通道61内的液态基质向储液腔71的回流，防止因供液通道61内液态基质的回流而造成下一次抽吸时供液延迟。例如，供液通道61的截面积为0.07mm²（或孔径0.3mm），通道长度≥2mm，气源40停止工作时供液通道61内的液态基质不会因储液腔71内的负压向储液腔71回流，从而可达到即时启动的效果。再例如，供液通道61的截面积为0.05mm²，通道长度≥1mm，也可实现即起即停的稳定供液。在另一些实施例中，供液通道61的水力直径小于等于0.3mm，也可实现即起即停的稳定供液。通常，供液通道61的截面积越小，需要达到即时启动的效果所需的供液通道61的通道长度越小。
再如图2-3所示，喷嘴雾化组件60可沿纵向穿设于储液组件70中并可与储液组件70同轴设置。该喷嘴雾化组件60还可包括套设于喷嘴63上的至少一个密封圈64。该密封圈64可采用硅胶等弹性材料制成，其可以为O形密封圈。密封圈64密封地配合于喷嘴63的外壁面和储液组件70的内壁面之间，以防止漏液。在本实施例中，密封圈64有两个，两个密封圈64分别设置于供液通道61的上下两侧，防止液态基质从供液通道61的上下两侧泄露。
储液组件70内还形成有连通储液腔71和供液通道61的下液通道72。该下液通道72可沿横向延伸，其可以为弱毛细力通道。下液通道72能够用于调节储液腔71供液至气流通道62的下液量和下液速度，保证供液至气流通道62的流量达到设计值，实现气流通道62的定量供液。下液通道72内的阻力太小，则会导致下液量较多和下液速度较快；下液通道72内的阻力太大，则会导致下液量较少和下液速度减慢。通常，可按照流量需求匹配设计下液通道72的尺寸，即在设计流量下下液通道72能产生匹配供液动力的阻力。下液通道72内的阻力需求与气流通道62内的负压相关。具体地，气流通道62内产生的负压为供液动力，而供液阻力则包括下液通道72和供液通道61的沿程阻力以及储液腔71内的负压。通过计算设计流量下下液通道72所需的沿程阻力，设计下液通道72的具体直径与长度。
进一步地，该电子雾化装置100还包括收容于外壳10中的发热件81。该发热件81与电源30电连接，其能够在通电后发热。发热件81的结构和加热形式不受限制，例如其可以为发热网、发热片、发热丝或发热膜等结构，其加热形式可以为电阻传导加热、红外辐射加热、电磁感应加热或者复合加热等加热形式。外壳10内还形成有输出通道80，发热件81可设置于输出通道80中并位于喷嘴63的上方。由喷嘴63喷出的液体颗粒向上撞击发热件81，经过发热件81蒸发加热后生成气溶胶，该气溶胶再由气流带出输出通道80，以供用户吸食或者吸入。
本实施例通过采用喷嘴63将连续流动的液态基质雾化成液体颗粒后再由发热件81蒸发的方式，由于喷嘴63雾化后形成的细小液体颗粒的表面积得到了极大的扩展，从而更容易加热蒸发，一方面可提高热量及气溶胶的转化效率，另一方面可降低发热件81蒸发过程的温度，实现低温雾化。在较低的加热雾化温度下，液态基质主要完成物理变化过程，从而克服了传统的多孔陶瓷或者多孔棉条件下因必须采用高温方式雾化而导致的液态基质热裂解变质的问题，更不会发生烧焦、积碳和重金属挥发等现象，从而能够保持不同液态基质所特有的成分和香精香料体系，最终使吸入者感受到与原始液态基质相对应的特有的口感。此外，发热件81与储液腔71不接触，发热件81不用长期浸泡在液态基质中，减少了发热件81对液态基质的污染，从而减少了雾化后生成的气溶胶中的杂质气体。
可以理解地，在其他实施例中，由喷嘴63喷出的液体颗粒也可向下撞击发热件81，即，发热件81也可设置于喷嘴63的下方；或者，由喷嘴63喷出的液体颗粒也可横向撞击发热件81，即，发热件81与喷嘴63处于或大致处于同一水平高度上。在另一些实施例中，该电子雾化装置100中也可以不设置有发热件81，即，喷嘴63雾化后的液体颗粒可直接经输出通道80输出，被用户吸食或者吸入。
进一步地，该电子雾化装置100还可包括设置于外壳10中并与控制模块20电连接的气流感应元件50。该气流感应元件50能够感应用户抽吸时的气流变化，其通常可以为负压传感器，例如咪头。用户抽吸动作制造负压，气流感应元件50感应负压而产生抽吸信号，该抽吸信号可传递至控制模块20以控制气源40和/或发热件81的工作。
进一步地，该电子雾化装置100还可包括可拆卸地罩设于外壳10上端的防尘罩90。在不需要使用电子雾化装置100时，可将防尘罩90罩设于外壳10的上端，防止灰尘等杂质进入输出通道80。
图4-5示出了本发明一个替代方案中的喷嘴雾化组件60，其与上述实施例的主要区别在于，本实施例中的喷嘴雾化组件60的供气通道621包括用于改变气流流向的至少一个旋流通道6213。
具体地，该至少一个旋流通道6213可设置于收缩通道6211内，且被配置为能使进入供气通道621的高速气流的至少部分沿雾化口6220的边缘流动。通过该至少一个旋流通道6213制造旋流，使原本通过收缩通道6211的能量集中在雾化口6220中心区域的射流改变为能量集中在雾化口6220边缘的具有切向速度的旋流，使得雾化口6220处切割液膜的气流速度更高、能量更大，同时在相同输入气流条件下的能量利用率更高，雾化所需的气液比更低，且切割后形成液体颗粒的粒径更小，轴向射流速度更低，有利于配合加热段的设计。旋流通道6213的设计原则为，从旋流通道6213的纵向一侧看向另一侧时不能看穿，即是使气流无法竖直通过旋流通道6213的设计结构。
本实施例中的喷嘴雾化组件60还包括旋流塞65，该旋流塞65设置于收缩通道6211中，用于形成旋流通道6213。该至少一个旋流通道6213可包括形成于旋流塞65外表面的旋流槽650和/或形成于旋流塞65内的旋流孔。具体地，在本实施例中，旋流塞65为圆台形，旋流塞65的外表面形成有两个弧形的旋流槽650。可以理解地，在其他实施例中，旋流槽650的个数也可以为两个或两个以上，该至少两个旋流槽650可沿旋流塞65的周向均匀间隔分布，且该至少两个旋流槽650相对于旋流塞65的中轴线呈旋转对称设置。
每一旋流槽650均具有远离雾化口6220的入口端651以及靠近雾化口6220的出口端652。在一些实施例中，该入口端651的截面积范围可以为0.4mm²~0.8mm²，该出口端652的截面积可以为0.04mm²~0.15mm²，每一旋流槽650的中心线与竖直方向的倾斜角可以为45°~75°，旋流槽650的高度可以为1.2mm~1.8mm。此外，旋流槽650的出口端652与雾化口6220之间具有一定的垂直距离，该垂直距离可以为0.6mm~1.2mm。可以理解，上述高度是指入口端651与出口端652在供气通道621的轴向上的距离，上述垂直距离是指出口端652与雾化口6220在供气通道621的轴向上的距离。
可以理解地，在其他实施例中，旋流塞65内也可形成有旋流孔。该旋流孔为倾斜的切向孔，该切向孔与雾化口6220的孔壁相切，从而达到使气流多数沿雾化口6220边缘流动的目的。
可以理解地，上述各技术特征可以任意组合使用而不受限制。
以上实施例仅表达了本发明的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制；应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，可以对上述技术特点进行自由组合，还可以做出若干变形和改进，这些都属于本发明的保护范围；因此，凡跟本发明权利要求范围所做的等同变换与修饰，均应属于本发明权利要求的涵盖范围。
