 本发明的实施方式
为了更清楚地表述本发明，下面结合附图对本发明作进一步地描述。
需要理解的是，“前”、“后”、“左”、“右”、“上”、“下”、“第一”、“第二”等术语仅是为了便于描述本发明的技术方案，而不是指示所指的装置或元件必须具有特殊的差别，因此不能理解为对本发明的限制。需要说明的是，当一个件被认为是“连接”另一个件，它可以是直接连接到另一个件或者可能同时存在居中件。除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。
图1及图2示出了本发明一些实施例中的电子雾化装置1，该电子雾化装置1可应用于烟液、液态药物等液态介质的加热雾化，其大致可呈圆柱状，并包括圆柱状的雾化器10以及与该雾化器100轴向可拆卸地连接的圆柱状主机20。雾化器10用于收容液态介质、加热雾化该液态介质以及输送雾气，主机20用于给雾化器10供电以及控制整个电子雾化装置1的开启或关闭等操作。可以理解地，该电子雾化装置1并不局限于呈圆柱状，其也可以呈椭圆柱等其他形状。
如图3至图7所示，雾化器10在一些实施例中可包括：用于与主机20可拆卸地连接的基座11；以下端沿纵向设置于基座11顶部的壳体12；下端由壳体12内部伸出壳体12，并沿纵向嵌置于基座11中以夹持壳体12的固定件13；位于壳体12内，并以下端沿纵向嵌置于固定件13中的雾化座14；位于壳体12内，并安装于雾化座14上的雾化组件15；位于壳体12内，并沿纵向安装于雾化组件15上的安装座16；位于壳体12内，并以下端沿纵向嵌置于该安装座16中的内管17；位于壳体12内，并以下部套设于固定件13、雾化座14、雾化组件15和安装座16上，以上部环绕内管17外围的外管18；以及沿纵向安装于壳体12、内管17以及外管18上端的吸嘴19。优选地，基座11、壳体12、固定件13、雾化座14、雾化组件15、安装座16、内管17、外管18以及吸嘴19呈共轴地组合在一起。
壳体12的内壁面和外管18的外壁面之间界定出一个储液腔120，以存储液态介质。雾化座14内界定有一个雾化腔140，用于将雾化组件15产生的雾化和空气进行混合。外管18的内壁面和内管17的外壁面之间界定出一个进气管道180，该进气管道180与该雾化腔140的雾化腔进气口相连通，以让外界空气能够进入雾化腔140。该内管17的内壁面界定出一个出气管道170，该出气管道170与该雾化腔140的雾化腔出气口相连通，以将雾化腔140内的雾气和空气混合物导出。在一些实施例中，吸嘴19可拆卸地封堵于储液腔120的上端，以便可以添加液态介质。
再如图3及图4所示，基座11在一些实施例中可包括一个导电的筒状主体部111、沿纵向一体结合于筒状主体部111下部的筒状导电结合部112、沿纵向绝缘地设置于结合部112中的筒状第一电极柱113以及沿纵向穿设于第一电极柱113上端的感应管道114。结合部112的外径可小于主体部111的外径，且其外壁面可形成有外螺纹，用以与主机20进行螺接。第一电极柱113的中心通孔和感应管道114的中心通孔相连通，气流可以从第一电极柱下端进，再从感应管道114的上端出，形成第一感应气道。感应管道114在一些实施例中可为筒状管，其上部出气端伸入到内管17内，并沿纵向悬设于内管170内（即出气端不与内管17的内壁面接触）。在一些实施例中，感应管道114的上部出气端最好高于安装座16的顶面所在的平面，以防止冷凝液进入到感应管道114中。感应管道114的上部出气端最好低于内管17从下往上的2/3高度，也即防止感应管道114的过长而容易倾斜，进而降低感应的灵敏性。本发明一些实施例中的雾化器10，通过在基座11设置感应管道114，充分利用结构内的固有空间，实现第一感应气道。降低了感应气道的设计难度，节省了空间，降低了成本。
壳体12在一些实施例中可呈筒状，并可采用透明或半透明材料制成。壳体12的下端设有一个孔径较小的颈部121。壳体12以该颈部121设置于基座11的主体部111的顶面。颈部121的内径与基座11的主体部111的内径相当。
固定件13在一些实施例中可呈筒状，其可包括位于下部的筒状下嵌入部131、位于上部的筒状上嵌入部132以及位于中部径向向外伸出的凸缘133。下嵌入部131的外径与基座11的主体部111的内径相适配，以贯穿壳体12的颈部121后紧密地嵌入该主体部111内。上嵌入部132的外径大于下嵌入部131的外径，并与外管18的内径相适配，以紧密地嵌入外管18中。凸缘133用于抵压在壳体12的颈部121上侧，而与基座11一道将该颈部121夹紧，从而实现壳体12于基座11上的固定。
雾化座14在一些实施例中可采用软胶等软质材料制成，其可包括本体部141、连接于本体部141下部的插入部142以及连接于本体部141上部的一对挡壁143，该一对挡壁143间隔相对的地设置于本体部141顶部的边缘上。本体部141顶面下凹形成雾化腔140。两挡壁143和雾化腔140的内壁面上形成有两道导气槽144，每一道导气槽144均由对应的挡壁143上端面向下沿伸至雾化腔140的底面。插入部142包括位于中部的第一槽孔1420和位于第一槽孔1420两相对侧的两个第二槽孔1422，第一槽孔1420和第二槽孔1422均由插入部142的下端面向本体部141延伸。第一槽孔1420的底面和雾化腔140的底面之间设有连通孔1424，该连通孔1424的孔径与感应管道114的外径相适配（例如，略小于感应管道114的外径），以供感应管道114紧密穿设于其中，防止漏液。雾化腔140的底面还下凹形成两个第三槽孔1401，该两个第三槽孔1401分别由该雾化腔140的底面朝向该两个第二槽孔1422延伸，使得该第三槽孔1401的底面和对应的第二槽孔1422的底面之间形成一个薄壁，以便雾化组件15安装时，其电极引线153能够刺穿该薄壁，而紧密地穿置于第二槽孔1422和第三槽孔1401中，防止漏液。
雾化组件15在一些实施例中可包括吸液体151、设置于吸液体151上的发热体152以及与发热体152连接的两电极引线153。吸液体151包括中心通孔1510和分别设置于吸液体151上端两相对侧的两卡臂1511。吸液体151以下部嵌置于雾化腔140，且吸液体15和发热体152与雾化腔140的底面之间形成有间隔，中心通孔1510将该间隔与吸液体151的上部相连通。两卡臂1511分别卡设于雾化座14的两挡壁143之间的两卡槽之中。两电极引线153分别与基座11的结合部112和第一电极柱113电性连接。
安装座16在一些实施例中可包括基部161、设置于基部161顶部的安装部162以及纵向贯穿基部161和安装部162的安装孔160，基部161包括两相对的端部1611、1612。一同参阅图8及图9，该两个端部1611、1612分别设有上下贯通的两个导气孔1613、1614，该两个导气孔1613、1614分别与雾化座14上的两个导气槽144对应设置。安装部162的外壁面两相对侧分别设有两个导气槽1621、1622，该两个导气槽1621、1622分别由安装部162的上端面向基部161沿伸。端部1611、1612的顶面分别设有导气槽1615、1616，导气槽1615、1616分别将导气槽1621、1622与导气孔1613、1614相连通。内管17的外径与安装孔160的孔径相适配，以便其以下端紧密地插设于该安装孔160中。
外管18在一些实施例中可包括位于下部的第一管段181、位于中部的第二管段182以及位于上部的第三管段183，第一管段181、第二管段182以及第三管段183的内径和外径均递减，使得外管18呈阶梯轴状。第一管段181的外径与壳体12的内径相适配，以便两者能够紧密地套接在一起。第一管段181的内径与固定件13的上嵌入部132的外径、雾化座14的本体部141外径、雾化组件15的吸液体151的两卡臂1511的端面之间的距离、以及安装座16的两个端部1611、1612的端面之间的距离相适配，以便第一管段181能够紧密地套设于这些部件的外围。第二管段182的内径与安装座16的安装部162的外径相适配，以便其紧密地套接于该安装部162。
第三管段183的内径大于内管17的外径，从而在第三管段183的内壁面和内管17的外壁面之间界定出一个环形的进气管道180，该进气管道180依次经由安装座16的导气槽1621、1622，安装座16的导气槽1615、1616，安装座16的导气孔1613、1614，以及雾化座14的导气槽144，与雾化腔140的进气口相连通。第二管段182和第三管段183的外壁面和壳体12界定出储液腔120。第一管段181顶壁两侧分别形成有一个开口1810，该两个开口1810分别与雾化组件15的吸液体151的两卡臂1511对应设置，从而将吸液体151与储液腔120导液连接。
吸嘴19在一些实施例中可包括主体部191、连接于主体部191下部的嵌入部192、连接于主体部191上部的吸嘴部193以及纵向贯通的出气孔190。主体部191的两相对侧分别开设有一个进气孔1910，该进气孔1910与进气管道180相连通。嵌入部192可拆卸地密封地封堵在储液腔120的上端环形开口中。出气孔190与内管17相连通。
于此，进气孔1910，进气管道180，导气槽1621、1622，导气槽1615、1616，导气孔1613、1614，导气槽144，雾化腔140，安装孔160、出气管道170，以及出气孔190依次串联形成一个完整的雾气输送通道。其中，进气孔1910，进气管道180，导气槽1621、1622，导气槽1615、1616，导气孔1613、1614，以及导气槽144一道形成雾气输送通道的用于引入外界空气的进气通道，安装孔160、出气管道170以及出气孔190一道形成雾气输送通道的用于输送雾气和空气混合物的出气通道。
如图10及图11所示，主机20在一些实施例中可包括带有收容腔210的筒状外壳21、设置于外壳21顶部的连接头22以及设置于收容腔210内的电池装置23和空气开关24。连接头22用于与雾化器10的基座11相螺接，其可包括一个筒状的可导电连接头主体221以及绝缘地设置于该连接头主体221中的筒状第二电极柱223。连接头主体221的内壁面形成有内螺纹，以与基座11的结合部112相螺接。第二电极柱223用于与第一电极柱113电性接触，且两者中心通孔相连通。连接头主体221和第二电极柱223分别与电池装置23的负极和正极电性连接，以将基座11的结合部112和第一电极柱113分别与电池装置23的负极和正极电性连接。外壳21和连接头22的结合部可设有进气孔212，以让外界空气能够进入收容腔210中。进气孔212、收容腔210以及第二电极柱223的中心通孔一道形成第二感应气道。该第二感应气道和第一感应气道一道形成电子雾化装置1的用于控制空气开关24工作的空气开关感应气道。具体而言，外界吸气时，气流依次经过进气孔212、收容腔210、第二电极柱223进入第一电极柱113以及感应管道114的过程中，在收容腔210形成负压，空气开关24在负压下启动。
电子雾化装置1工作时，使用者从吸嘴19的吸嘴部193处吸气，吸气产生的负压经过雾气输送通道的出气通道传递给空气开关感应气道，空气开关24开启，让电源装置23给雾化组件15供电，开始雾化液态介质。与此同时，外界空气经由雾气输送通道的进气通道进入雾化腔140中，与雾气进行混合。雾气和空气的混合物再经由雾气输送通道的出气通道进入使用者口中。
可以理解地，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。
