下面结合附图和实施例对本申请进行详细的说明。
请参阅图1，图1为本申请一实施例提供的电子雾化装置的结构示意图；在本实施例中，提供一种电子雾化装置100。该电子雾化装置100可用于加热并雾化气溶胶生成基质，以形成气溶胶，供用户抽吸；其中，该电子雾化装置100具体可为电子烟、便携医疗雾化器，气溶胶生成基质具体可为烟油、药物液体或者其它可以雾化后抽吸的液体。
具体的，电子雾化装置100包括雾化器10和主机20。雾化器10和主机20可拆卸连接。其中，雾化器10用于在通电时加热并雾化气溶胶生成基质；主机20内设置有电源组件，雾化器10插接在主机20的一端端口，并与主机20内的电源组件连接，以通过电源组件给雾化器10供电。当雾化器10需要更换时，可以将雾化器10拆卸并在主机20上 安装新的雾化器10，实现主机20的重复使用。
当然，该电子雾化装置100还包括现有电子雾化装置中的其它部件，比如，咪头、支架等，这些部件的具体结构与功能与现有技术相同或相似，具体可参见现有技术，在此不再赘述。
在一具体实施例中，请参阅图2，图2为本申请一实施例提供的雾化器的结构示意图；雾化器10具体可包括气泡流腔体11、气泡流喷射头12、储气腔体13、储液腔体14以及压力容器15。
其中，气泡流腔体11用于使气溶胶生成基质与气体混合并形成气泡流；其中，气溶胶生成基质的粘度可为粘度不小于200cps的高粘度气溶胶生成基质；在具体实施例中，当流动的气溶胶生成基质与气体接触后，二者形成若干气泡31，若干气泡31随气溶胶生成基质的流动汇聚形成气泡流。
具体的，气泡流腔体11可为一具有容纳腔的柱状体结构，气溶胶生成基质与气体具体在容纳腔内混合并形成气泡流。
其中，气泡流喷射头12具体可对应设置在气泡流腔体11的一端，并对应气泡流腔体11的中间位置，且与气泡流腔体11连通，用于喷射气泡流以雾化形成气溶胶41；具体的，参见图3，图3为本申请一实施例提供的气泡雾化的原理图；气泡流喷射头12形成有一贯通孔，气泡流腔体11内的气泡流经过贯通孔时，经贯通孔的孔壁拉伸变形，并在贯通孔远离气泡流腔体11的一端端口破裂，进而形成粒径较小的气溶胶41；其中，通过形成气泡31，以利用气泡流的表面张力实现雾化，不仅能够减小气溶胶生成基质的粘度对雾化过程的影响，有效提高气溶胶41的雾化量，且能够使气溶胶生成基质的各组分被均匀地带出，保证了口感的一致性。
具体的，贯通孔的径向尺寸从靠近气泡流腔体11的一端朝向远离气泡流腔体11的一端逐渐减小，以利用气泡31的表面对气溶胶41形成基质进行雾化。当然，贯通孔的径向尺寸从靠近气泡流腔体11的一端朝向远离气泡流腔体11的一端保持不变，即贯通孔为等径孔。
其中，储气腔体13与气泡流腔体11连通，用于存储气体；储液腔 体14用于存储气溶胶生成基质；压力容器15与储气腔体13和储液腔体14连通，用于驱动储气腔体13内的气体流向气泡流腔体11，以及驱动储液腔体14内的气溶胶生成基质流向气泡流腔体11，从而使进入气泡流腔体11的气溶胶生成基质与进入气泡流腔体11的气体接触并形成若干气泡31。
在一具体实施例中，储气腔体13设置在气泡流腔体11的外侧，并与气泡流腔体11具有第一公共墙壁，且第一公共墙壁上开设有若干第一连通孔，以连通储气腔体13和气泡流腔体11，从而使储气腔体13内的气体能够通过第一连通孔进入气泡流腔体11；可以理解的是，气泡31在第一连通孔的朝向容纳腔的一端的端口处形成。
具体的，在实施例中，参见图2，储气腔体13沿气泡流腔体11的外围设置，且环绕气泡流腔体11的外围一周。且第一公共墙壁可为环形侧壁；储气腔体13形成一环形腔体，以存储气体。
在另一具体实施例中，参见图4，图4为本申请另一实施例提供的雾化器的结构示意图；气泡流腔体11设置在储气腔体13的外侧，并与储气腔体13具有第一公共墙壁；且第一公共墙壁上开设有若干第一连通孔，以连通储气腔体13和气泡流腔体11。具体的，若干第一连通孔在第一公共侧壁上均匀分布，以使形成的气泡31均匀分布在气泡流腔体11内。
具体的，在该实施例中，储气腔体13具有一柱形腔，以存储气体；气泡流腔体11包括第一腔体部和第二腔体部，第一腔体部沿储气腔体13的外围设置，并环绕储气腔体13的一周设置，并与储气腔体13具有第一公共子墙壁；第二腔体部设置在储气腔体13与气泡流喷射头12之间，并与储气腔体13具有第二公共子墙壁；其中，第一公共子墙壁和第二公共子墙壁形成第一公共墙壁。
具体的，第一腔体部和第二腔体部一体成型并连通；参见图4，气泡流腔体11的竖向截面约为“门”字型。
在一具体实施例中，储液腔体14和压力容器15设置在气泡流腔体11远离气泡流喷射头12的一端，以方便用户用手抓持；在一具体实施 例中，参见图2，储液腔体14和压力容器15沿气泡流腔体11的径向方向并排设置；在另一具体实施例中，参见图4，储液腔体14环绕压力容器15的外围一周设置；当然，在其他实施例中，压力容器15也可环绕储液腔体14的外围一周设置。
具体的，参见图2和图4，该雾化器10还包括第一控制元件16、第二控制元件17、第三控制元件18和第四控制元件19。
在一具体实施例中，储液腔体14和气泡流腔体11具有第二公共墙壁，储气腔体13和压力容器15具有第三公共墙壁，储液腔体14和压力容器15具有第四公共墙壁；气泡流喷射头12和气泡流腔体11具有第五公共墙壁。
其中，第一控制元件16具体可设置在第二公共墙壁上，用于控制气泡流腔体11与储液腔体14连通；具体的，当需要使用该雾化器10时，控制第一控制元件16开启，以连通气泡流腔体11和储液腔体14。
第二控制元件17具体可设置在第三公共墙壁上，用于控制压力容器15和储气腔体13连通；具体的，当需要使用该雾化器10时，控制第二控制元件17开启，以连通压力容器15和储气腔体13，从而通过压力容器15驱动储气腔体13内的气体通过第一连通孔流向气泡流腔体11。
第三控制元件18具体设置在第四公共墙壁上，用于控制压力容器15和储液腔体14连通；具体的，当需要使用该雾化器10，并开启第一控制元件16和第二控制元件17之后，控制第三控制元件18开启，以连通压力容器15和储液腔体14，从而通过压力容器15驱动储液腔体14内的气溶胶生成基质朝向气泡流腔体11流动；可以理解的是，当开启第一控制元件16时，储液腔体14内的气溶胶生成基质很难自发地流向气泡流腔体11，需要压力容器15驱动才可顺利进入气泡流腔体11，这样能够避免在雾化器10闲置不用时，气溶胶生成基质进入气泡流腔体11，并经第一连通孔进入储气腔体13内的问题发生；而当第三控制元件18开启后，由于压力容器15同时连通储气腔体13和储液腔体14，能够通过压力容器15控制储气腔体13与气泡流腔体11内的压力平衡， 进而能够防止进入气泡流腔体11内的气溶胶生成基质通过第一连通孔进入储气腔体13内。
第四控制元件19具体设置在第五公共墙壁上，用于控制气泡流喷射头12与气泡流腔体11连通。具体的，当用户需要抽吸气溶胶41时，控制第四控制元件19开启，以连通气泡流喷射头12与气泡流腔体11，使气泡流能够通过气泡流喷射头12进行喷射雾化。
在一具体实施例中，参见图5，图5为本申请又一实施例提供的雾化器的结构示意图；该雾化器10还可包括检测器23和控制器24。
其中，检测器23可设置在气泡流喷射头12远离气泡流腔体11的一端的端口，用于检测并发送雾化器10的开启信号；具体的，检测器23可为传感器，开启信号具体可为气泡流喷射头12的远离气泡流腔体11的一端的端口的负压信号；比如，当用户抽吸时，气泡流喷射头12对应的位置形成一负压，传感器感测该负压，并生成负压信号。控制器24与检测器23连接，用于接收开启信号并根据开启信号控制第四控制元件19开启，从而使气泡流喷射头12与气泡流腔体11连通。
具体的，上述第一控制元件16、第二控制元件17、第三控制元件18和/或第四控制元件19为控制阀。
具体的，上述压力容器15可以与气泡流腔体11、储气腔体13和储液腔体14一体成型，也可为单独的压力气罐，里面储存具有一定压力的气体；由于压力气罐无需使用压力泵，从而能够有效降低产品噪音。在一个实施例中，雾化器10具有一体成型的壳体，该壳体形成气泡流腔体11、储气腔体13、储液腔体14和压力容器15。在另一个实施例中，雾化器10具有一体成型的外壳以及设置于外壳中的多个隔板，以将该外壳内的空间分割成气泡流腔体11、储气腔体13、储液腔体14和压力容器15。
在一具体实施例中，为了降低喷射形成的气溶胶41的粒径，该雾化器10可包括加热元件22，加热元件22至少设置在气泡流喷射头12远离气泡流腔体11的一端，以对从气泡流喷射头12喷射出的气溶胶41进行加热并进行进一步雾化，从而进一步降低气溶胶41的粒径，以将 气溶胶41的粒径控制在一定范围之内。具体的，加热元件22的加热温度可为60℃-90℃。
在具体实施例中，该雾化器10还包括吸嘴组件21，吸嘴组件21可设置在气泡流喷射头12远离气泡流腔体11的一端，并与气泡流喷射头12连通，用于抽吸气泡流喷射头12喷出的气溶胶41。具体的，吸嘴组件21可包括导气管，导气管的一端套设在气泡流喷射头12的周围。在该实施例中，加热元件22具体设置在气泡流喷射头11与吸嘴组件21之间。
具体的，加热元件22的一端可与气泡流腔体11的朝向气泡流喷射头12的一侧的外侧壁抵接，且环绕气泡流喷射头12设置。在一具体实施例中，加热元件22可呈环状结构，其具体环绕导气管设置，以对从气泡流喷射头12喷射出的气溶胶41在经过导气管的过程中持续对其进行加热。在一个实施例中，雾化器10的壳体的一端具有凹槽，气泡流喷射头12设置于凹槽底部，吸嘴组件21的导气管的一端设置于凹槽中与凹槽的底壁抵接且套设在气泡流喷射头12的周围，加热元件22环绕吸嘴组件21的导气管设置，且与凹槽的侧壁和底壁抵接。
以下对该雾化器10的作用原理进行详细描述。
当控制器24检测到用户的启动信号时，控制第一控制元件16和第二控制元件17开启，以使压力容器15与储气腔体13连通，使储液腔体14气泡流腔体11连通，从而利用压力容器15驱动储气腔体13的气体进入气泡流腔体11内；然后控制第三控制元件18开启，以使压力容器15与储液腔体14连通，并利用压力容器15驱动储液腔体14内的气溶胶生成基质进入气泡流腔体11内，从而使气溶胶生成基质与气体在第一连通孔的交界面处形成气泡31，气泡31随气溶胶生成基质的流动形成气泡流。
之后，当控制器24通过检测器23检测到雾化器10的开启信号(例如抽吸信号)时，控制器24控制第四控制元件19开启，气泡流在压差作用下朝向气泡流喷射头12移动，并经气泡流喷射头12的孔壁的拉伸变形，并在气泡流喷射头12的出口处破碎并形成气溶胶41；同时加热 元件22开启工作并对形成的气溶胶41进行进一步的加热雾化，以得到粒径较小的气溶胶41；当检测器23检测不到开启信号后，控制第四控制元件19关闭，从而完成气溶胶41的抽吸过程。
本实施例提供的雾化器10，采用气体和气溶胶生成基质在雾化器10混合的两相流雾化方式，使气溶胶生成基质在喷射雾化之前先与气体混合并形成气泡流，以利用气泡流的表面张力实现雾化，从而在减小气溶胶生成基质的粘度对雾化过程的影响的同时，不仅能够有效提高气溶胶41的雾化量，且能够使气溶胶生成基质的各组分被均匀喷出；同时，通过将压力容器15设置为压力气罐，使得该雾化器10无需使用压力泵，有效降低了产品噪音；另外，通过设置加热元件22，以对形成的气溶胶41进行加热，从而能够有效降低最终得到的气溶胶41的粒径，使得气溶胶41的粒径可控制在一定范围之内。
