如图1和图4所示，本实用新型提供了一种气溶胶发生装置，该气溶胶发生装置包括雾化器100以及与雾化器100电性连接的电源装置，其中，雾化器100包括储液组件10和设置在储液组件10一端的雾化组件20，储液组件10内储存有气溶胶形成基质。使用时，储液组件10内的气溶胶形成基质进入雾化组件20内，所述电源装置给雾化组件20供电，雾化组件20雾化气溶胶形成基质产生烟雾供用户抽吸。
在其中一个具体的实施方式中，储液组件10包括储液管14，储液管14大致呈下端具有开口的中空筒状结构，雾化组件20安装在储液管14的下端开口。储液管14的顶壁上开设有出烟口11，储液管14的内壁上位于出烟口11四周的部位沿储液管14的轴向向下延伸形成连通管12，连通管12的内腔与出烟口11相连通。储液组件10还包括与连通管12连接的通气管13，本实施方式中，通气管13的上端套设在连通管12的外部，通气管13的下端与雾化组件20连接，可以理解地，通气管13与连通管12之间还可以通过螺纹连接或卡接等方式连接。通气管13内部中空形成出烟通道131，出烟通道131与连通管12的内腔连通，通气管13的外壁、储液管14的内壁以及雾化组件20三者之间围设的空间形成用于储存气溶胶形成基质的储液腔15。本实施方式中，储液管14可以由塑料、玻璃等透明或半透明材料制成，以便于用户观察储液管14内储存的气溶胶形成基质余量，方便用户及时注液或及时更换雾化器100。可以理解地，在其它未示出的实施方式中，储液管14还可以由金属材料或玻璃结合金属材料制成，此处不做限制。
如图2-图5所示，雾化组件20包括雾化底座21和加热结构23，雾化底座21上设置有雾化腔221和进气通道211，雾化底座21的上端面凹陷形成有安装槽212，加热结构23包括吸液件231和发热件232，吸液件231收容在安装槽 212内，发热件232夹设在吸液件231的下端面与安装槽212的槽底壁之间，吸液件231的上端面收容在雾化腔221中，进气通道211用于将外部空气引导至雾化腔221中。可以理解地，在未示出的其他实施方式中，加热件232的设置位置不做限定，只需要满足加热件232与吸液件231接触并传导热量即可，例如：加热件232夹设在吸液件231的侧面与安装槽212的槽侧壁之间，或者，加热件232设置在吸液件231的上端面，或者，加热件232设置在吸液件231中。
在一个具体的实施方式中，安装槽212的槽底壁沿雾化底座21的轴向向上延伸形成有导气管213，导气管213的上端和雾化底座21的下端贯通，雾化底座21的下端开口形成进气端，所述进气端与导气管213的内腔连通，导气管的上端开口形成出气端，进气通道211由导气管213的内腔形成，导气管213的出气端与吸液件231的上端面之间具有预设的高度差，即进气通道211的出气端高于吸液件231的上端面。在本实施方式中，吸液件231收容在安装槽212内，未被加热结构23及时雾化的气溶胶形成基质或遇冷产生的冷凝液在重力作用下会存储在安装槽212中，并被吸液件231吸附，气溶胶发生装置以任何角度放置，被吸液件231吸附的积液不会通过导气管213、进气通道211泄漏至气溶胶发生装置外部。而当使用气溶胶发生装置时，聚集在安装槽212的槽底的气溶胶形成基质优先被设置在安装槽212的槽底壁上的发热件232雾化，进而防止聚集在安装槽212的槽底壁上的气溶胶形成基质泄露至气溶胶发生装置外部。
雾化底座21的外周面上凸设有限位部214，储液组件10的下端与限位部214相配合，储液组件10与雾化组件20组装到位时，储液组件10的下端面与限位部214的上端面相抵持，从而对储液组件10的安装起到限位作用。为了增 强储液组件10与雾化组件20之间的密封性，储液管14的内壁与雾化底座21的外壁之间夹设有密封件215，密封件215由硅胶或橡胶等密封材料制成。本实施方式中，储液组件10与雾化组件20组装时，储液管14套设在雾化底座21的外部，可以理解地，在其它未示出的实施方式中，储液管14与雾化底座21之间还可以通过卡接或插接等连接方式连接。可以理解地，在其它未示出的实施方式中，储液管14与雾化底座21一体成型，储液管22还包括上端开口，加热结构23以及通气管13由储液管22的上端开口装入。
在其中一个具体的实施方式中，雾化组件20还包括设置在雾化底座21一端的连接件22，连接件22安装在雾化底座21的顶部，且连接件22的下端面与雾化底座21的上端面相抵持，连接件22上开设有与安装槽212连通的进液孔224，吸液件231的上端面对应进液孔224与连接件22的下端面相贴合，且储液腔15内的气溶胶形成基质通过进液孔224进入安装在安装槽212内的吸液件231上，当吸液件231吸附气溶胶形成基质至饱和状态时，储液腔15中的气溶胶形成基质停止流至吸液件231。可以理解地，在其它未示出的实施方式中，吸液件231的上端面也可以错开进液孔224设置，只需满足吸液件231设置在储液腔15与雾化腔221之间，以隔断储液腔15与雾化腔221的直接连通即可。连接件22的底部部分沿连接件22的轴向向上凹陷形成连通槽225，连通槽225与进气通道211连通，连接件22安装在雾化底座21上时，雾化腔221由连通槽225的槽壁、吸液件231的上端面以及导气管213的外壁共同围合形成。连接件22的顶壁沿连接件22的轴向向上延伸形成中空的连接管222，连接管222的上端与通气管13相连接，连接管222的内腔与出烟通道131以及雾化腔221均连通，储液腔15由通气管13的外壁、储液管14的内壁、连接件22的顶壁以及连接管222的外壁共同围合形成，本实施方式中，连接管222的上端套设 在通气管13的外部，连接管222的内壁沿连接管222的径向向连接管222的中心轴方向延伸形成有限位凸起223，通气管13与连接管222组装到位时，通气管13的下端抵持在限位凸起223上，从而对通气管13的安装起到限位作用。可以理解地，在其它未示出的实施方式中，通气管13与连接管222之间还可以通过卡接或磁性连接等连接方式连接。用于供外部空气进入到雾化腔221内，并供烟雾和外部空气的混合物流出气溶胶发生装置进入用户口中的通道为气流通道，在本实施例中，气流通道包括进气通道211、导气管213的内腔、雾化腔221、出烟通道131以及出烟口11。
在一个具体的实施方式中，连接件22由储液管14的下端开口装入，并连接至储液管14。可以理解地，在其它未示出的实施方式中，连接件22与储液管14一体成型，进液孔224和/或连接管222的上端开口构成储液管22的下端开口，储液管22还包括上端开口，通气管13由储液管22的上端开口装入，并连接至连接件22。可以理解地，在其它未示出的实施方式中，可以省略连接件22，吸液件231的上端面与通气管13的下端面相贴合，使得吸液件231的一部分上端面与储液腔15中的气溶胶形成基质接触，吸液件231的另一部分上端面收容在通气管13的内腔中，通气管13的内腔既作为出烟通道131，也作为雾化腔221，储液腔15由通气管13的外壁、储液管14的内壁以及雾化底座21的上端面共同围合形成。
在一个具体的实施方式中，通气管13与连接件22之间设置有挡液件24，挡液件24设置在限位凸起223与通气管13之间，并分隔气流通道中雾化腔221至出烟口11的通道部分，挡液件24的底壁抵持在限位凸起223的顶壁上，挡液件24的顶壁抵持在通气管13的下端。挡液件24用于过滤由雾化腔221流至出烟口11的气体，挡液件24上开设有多个透气孔241，所述气流通道中的气体 可以通过透气孔241流通至用户口中，同时挡液件24能够阻止雾化腔221内的冷凝液、未雾化的气溶胶形成基质等通过所述气流通道进入用户口中或泄露至气溶胶发生装置外部。可以理解地，挡液件24还可以设置在连通管12与通气管13之间，并分隔气流通道中雾化腔221至出烟口11的通道部分，同样能够阻止雾化腔221内的冷凝液、渗漏的气溶胶形成基质等通过所述气流通道进入用户口中或泄露至气溶胶发生装置外部。可以理解地，挡液件24还可以设置在通气管13中，或者设置在连接管222中，或者设置在连通管12中，并分隔气流通道中雾化腔221至出烟口11的通道部分，同样能够阻止雾化腔221内的冷凝液、渗漏的气溶胶形成基质等通过所述气流通道进入用户口中或泄露至气溶胶发生装置外部。
在一个具体的实施方式中，连接件22的底壁上凸设有连接柱226，雾化底座21上设置有与连接柱226配合的安装孔，连接件22与雾化底座21连接时，连接柱226插设在对应的所述安装孔内，以便连接件22与雾化底座21之间的定位连接。
在一个具体的实施方式中，雾化底座21上安装有两个电极连接件216，其中一个电极连接件216与所述电源装置的正、负极中的一个电极电性连接，另一个电极连接件216与所述电源装置的正、负极中的另一个电极电性连接，每个电极连接件216的上端开设有与安装槽212相连通的插设槽2161，发热件232上的两端连接有两个引脚2321，其中一个引脚2321与一个插设槽2161相对应，每个引脚2321插设在对应的插设槽2161内与电极连接件216电性连接，从而使得引脚2321与所述电源装置电性连接，电能通过引脚2321供给到发热件232。本实施方式中，发热件232设置在吸液件231的下方，且引脚2321插设在插设槽2161内，即使有气溶胶形成基质沿着引脚2321渗漏，也不会进入雾化腔221 内或者通过与雾化腔221连通的气流通道泄漏至外部。可以理解地，在其他实施方式中，发热件232上的两端设置有两个引脚，电极连接件216抵持在发热件232的引脚上，实现发热件232与电极连接件216的电性连接。
在其中一个具体的实施方式中，发热件232与安装槽212的槽底壁之间还设置有隔热件25，引脚2321穿过隔热件25后插设在对应的插设槽2161内，隔热件25由硅胶、陶瓷或者金属等耐高温材料制成，防止发热件232发热时，发热件232上的热量通过安装槽212的槽底壁传导至雾化底座21上进而传导至气溶胶发生装置外部，造成资源浪费。
吸液件231具有吸收气溶胶形成基质的功能，可以理解地，吸液件231为多孔状的吸液件，吸液件231可以是棉花、多孔陶瓷、纤维绳、泡沫金属、泡沫石墨中的一种、两种或两种以上的组合。本实施方式中，吸液件231为棉花。发热件232为片状结构，发热件232为可通电产热的发热体，本实施方式中，发热件232为金属发热片，且发热件232与引脚2321为一体成型结构。
当用户使用时，所述电源装置向发热件232供电，发热件232发热后加热吸液件231上吸收的气溶胶形成基质，进而使气溶胶形成基质生成烟雾，烟雾散发至雾化腔221内，外界空气经过进气通道211以及导气管213进入雾化腔221内与烟雾混合，通过进气通道211以及导气管213进入气溶胶发生装置的空气经过雾化腔221时，携带烟雾一同经过出烟通道131以及出烟口11进入用户口中。
本实用新型提供的雾化器100，通过在雾化组,20上开设连通所述雾化腔221的进气通道211，吸液件231设置在储液腔15与雾化腔221之间，以隔断储液腔15与雾化腔221的直接连通，同时进气通道211的出气端相对于吸液件231靠近出烟口11，使得吸液件231上未被发热件232及时雾化的气溶胶形成基质 或烟雾蒸气遇冷产生的冷凝液以及渗漏的气溶胶形成基质等不易泄露至气溶胶发生装置外部。
本实用新型提供的气溶胶发生装置，因其具有上述雾化器100全部的技术特征，故具有与上述雾化器100相同的技术效果。
