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，该电子雾化装置可用于医疗、美容、保健、休闲吸食等技术领域。该电子雾化装置用于在通电时加热并雾化气溶胶生成制品以形成气溶胶供使用者抽吸。其中，该气 溶胶生成制品可采用固体基质，可以包括香草叶、茶叶、薄荷叶等植物叶类一种或多种的粉末、颗粒、碎片细条、条带或薄片中的一种或多种；或者，固体基质可以包含附加的挥发性香味化合物，以在基质受热时被释放。当然，气溶胶生成制品也可为液体基质或膏状基质，比如添加香气成分的油类、药液等。
该气溶胶生成装置包括加热组件10和电源组件20。其中，加热组件10用于收容并在通电时雾化气溶胶生成制品以形成气溶胶；加热组件10的具体结构与功能可参见以下任一实施例所涉及的加热组件10。电源组件20与加热组件10电连接，用于向加热组件10供电。电源组件20可包括电源和导电件；其中，电源可为干电池或锂电池等，导电件可为电源线或其他可导电的导电件。当然，该电子雾化装置还可以包括壳体30，壳体30用于安装加热组件10和电源组件20。
请参阅图2-3，其中，图2为本申请一实施例提供的加热组件的结构示意图，图3为图2中加热组件的拆解结构示意图；在本实施例中，提供一种加热组件10，该加热组件10包括发热体11、电极12、底座13以及导电元件14。
其中，如图2或图3所示，发热体11可包括基体111和形成于基体外表面的发热层112。基体111具有底壁和与底壁连接的侧壁；基体111的侧壁与底壁配合形成中空结构，该中空结构作为基体111的收容腔110，收容腔110用于收容气溶胶生成制品。基体111采用绝缘材料制备，基体111可以是石英玻璃、陶瓷或云母等耐高温的绝缘材料，以防止两个电极12短路。优选地，基体111可为透明石英。当然，基体111也可以采用导电材料制备，此时可在基体111表面涂覆绝缘层。在一具体实施例中，基体111为圆柱状陶瓷管。需要说明的是，以下实施例中所涉及的基体111的内表面均指收容腔110的内壁面，基体111的外表面均指收容腔110的外壁面。
发热层112设置于基体111侧壁的外表面，当然，也可设置于基体111底壁的外表面，用于在通电时发热以加热并雾化气溶胶生成制品；以下实施例均以此为例。当然，发热层112也可形成于基体111的内表 面。具体的，发热层112可采用丝印、溅射、涂敷、印刷等方式形成于基体111侧壁的外表面。其中，由于红外线具有一定的穿透性，不需要介质，加热效率较高，且对气溶胶生成制品的烘烤更加均匀。在具体实施例中，该发热层112具体可选用红外发热层，例如红外陶瓷涂层。红外发热层可为红外发热膜，红外发热膜的厚度和面积不限，可以根据需要选择。其中，红外发热层可以为金属层、导电陶瓷层或导电碳层。在具体实施例中，红外发热层通电时辐射红外线，以加热收容腔110中的气溶胶生成制品。其中，红外加热波长2.5um～20um，针对加热气溶胶生成制品的特点，通常加热温度需要350℃以上，能量辐射极值主要在3～5um波段。当然，发热层112还可以是发热膜；比如铜膜或铝膜等可以导电的膜。
如图2或图3所示，电极12呈弧形并整体设置于基体111侧壁的外表面，且多个电极12沿发热体11的周向方向间隔设置于发热体的同一端；在本实施例中，多个电极12沿发热体11的周向方向间隔设置于发热体的底壁。当然，在其它实施例中，也可以是电极12的部分设置于基体111侧壁的外表面，即，电极12除设置于基体111侧壁的外表面的部分外，还包括其它部分，比如，电极12还包括设置于基体111的底壁的外侧面的部分；本申请对此并不加以限制。具体的，加热组件10还包括若干间隔设置的导电电路121；若干导电电路121与多个电极12一一对应连接，且沿发热体11的长度方向延伸至发热层112背离电极12的一端，以将电极12与发热层112连通；且多个电极12中至少两个电极12的极性相反，即多个电极12中至少有一个为正极、一个为负极，从而向发热层112供电，使发热层112通电后发热以加热气溶胶生成制品；以下实施例均以此为例。其中，导电电路121可呈直线型或曲线型。当然，在其它实施例中，电极12的至少部分也可形成于基体111底壁的外表面并通过导电电路121与发热层112连接。
电极12和/或导电电路121可以是涂覆于发热体11上的导电涂层，导电涂层可以是金属涂层、导电银浆或者导电胶带等，也可以是沉积于发热体11表面的金属等，例如金膜、铝膜或铜膜。
如图3所示，底座13呈环状，具有底壁和与底壁连接的环状侧壁，底座13的底壁与环状侧壁围设限定出限位腔131；发热体11的部分插接于底座13的限位腔131内。在该实施例中，底座13还具有与其底壁相背离的端部面，端部面具体为底座13上沿其轴向方向背离其底壁的一端的表面，且该端部面连接底座13环状侧壁的内壁面与外壁面；其中，底座13的轴向方向平行于发热体11插入底座13的插接方向A(见下图4)。导电元件14包括依次连接的本体部141和电连接部142；其中，本体部141位于底座13的外侧，用于耦接电源。具体地，本体部141可通过导电件以与电源耦接，从而实现电源组件20向发热体11供电。需要说明，在本实施例中，底座13的侧壁背离限位腔131的一侧、底座13的端部沿底座13的径向方向远离底座13的一侧均为底座13的外侧。
在具体实施例中，请参见图4，图4为导电元件与底座装配后的结构示意图；导电元件14的本体部141的至少部分搭接于底座13的端部面；需要说明，本申请所涉及的搭接是指本体部141的至少部分承载于底座13的端部面，即底座13的端部对本体部141承载于其上的部分起到一定的支撑作用；电连接部142与本体部141搭接于底座13的端部面的部分连接，并位于底座13的侧壁的内侧，使得发热体11插接于底座13的限位腔131后，导电元件14的电连接部142与位于发热体11外表面的电极12接触而实现电连接，并在发热体11的重力作用下紧密抵接，有效增加了二者的连接可靠性。并且，由于本体部141的至少部分搭接于底座13的端部面，能够通过底座13对导电元件14进行支撑，从而在发热体11的部分插接于底座13内并对导电元件14的电连接部142进行挤压的过程中，能够使导电元件14紧密挂接在底座13上而不会与底座13之间沿底座13的轴向方向发生相对移位或脱离，使得导电元件14能够准确地连接于电极12，避免其发生电连接部142与电极12错位导致加热组件10无法正常工作。可以理解的是，对应于电极12，导电元件14的数量也为多个，且沿底座的周向方向间隔设置，以分别与多个电极12一一对应连接。在本实施例中，电极12的数量为两个， 且两个电极12的极性相反，即一个正极、一个负极；对应的，两个导电元件14分别与正极电极12和负极电极12连接。
具体的，如图4所示，导电元件14的电连接部142包括弯折部1421和抵接部1422；其中，弯折部1421连接于本体部141的靠近底座13内部的一端，即靠近底座13的限位腔131的一端，并朝向底座13的中心位置延伸；抵接部1422连接于弯折部1421远离本体部141的一端，并沿发热体11插入底座13的插接方向A延伸，以与位于发热体11外表面的电极12抵接。
在具体实施例中，弯折部1421和/或抵接部1422与发热体11插入底座的13的插入方向A之间的夹角大于90°小于180°，即，弯折部1421和/或抵接部1422与插入方向A之间的夹角为钝角，从而减少或避免发热体11在插入底座13并与电连接部142抵接时发生卡顿现象，使得发热体11在插入底座13时更加顺畅，不仅便于安装，而且还可避免发热体11在插入底座13的过程中对电连接部142造成损坏。
具体的，电连接部142具有弹性，其具体可为弹性导电薄片，比如具有弹性的铜合金、钢材等材料。如图4所示，电连接部142悬空设置于底座13内的第一位置，即如图5a所示，图5a为电连接部处于第一位置时的结构简图；在发热体11未插入底座13时，电连接部142具体处于第一位置；而如图5b所示，图5b为电连接部在发热体的挤压下处于第二位置时的结构简图；在发热体11插入底座13后，电连接部142在发热体11的挤压下，电连接部142发生弹性形变并由第一位置切换至第二位置；此时，电连接部142具有朝向第一位置运动的弹性作用力，电极12与电连接部142之间通过该弹性作用力紧密接触，以实现二者的可靠连接。可以看出，由于电连接部142的弹性形变，使得α大于α′，其中，α′为电连接部142处于第一位置时，弯折部1421与抵接部1422之间的夹角；α为电连接部142处于第二位置时，弯折部1421与抵接部1422之间的夹角；同时，由于发热体11插入底座13时电连接部142的弹性形变，使得弯折部1421和/或抵接部1422与发热体11插入底座的13的插入方向A之间的夹角也在一定程度上变大，但仍然 大于90°小于180°。具体的，弯折部1421可以绕弯折部1421与本体部141的连接处沿发热体11的插接方向A上下弯折，以在第一位置和第二位置之间进行切换。
请继续参阅图4，在该实施例中，导电元件14的本体部141包括电连接的第一本体部1411和第二本体部1412；其中，第一本体部搭接于底座13的端部面，电连接部142连接于第一本体部1411远离第二本体部1412的一端，使得导电元件14挂接于底座13上，从而使得发热体11在插接于底座13时，本体部141能够通过底座13对导电元件14进行支撑，从而在发热体11的部分插接于底座13内并对导电元件14的电连接部142进行挤压的过程中，能够使导电元件14紧密挂接在底座13上而不会与底座13之间沿底座13的轴向方向发生相对移位或脱离，使得导电元件14能够准确地连接于电极12，避免其发生电连接部142与电极12错位导致加热组件10无法正常工作。其中，第二本体部1412沿底座13的轴向方向延伸，即第二本体部1412沿与底座13的环形侧壁的径向方向垂直的纵向方向延伸，并位于所述底座13的侧壁的外侧，用于耦接电源；容易理解，第二本体部1412远离第一本体部1411的一端用于耦接电源，该连接方式受发热体11的温度的影响小，连接可靠性较高，且该连接方式对发热体11的材质没有限制，使用范围更广。具体地，第二本体部1412远离第一本体部1411的一端通过与导电件连接，从而使得导电元件14与电源耦接，实现电源组件20向发热体11供电。
在本实施例中，导电元件14包括一个本体部141和多个电连接部142；其中，本体部141为弧形面状，多个电连接部142沿本体部141的周向方向间隔设置，或多个电连接部142均匀分布于本体部141的预设区域；具体的，第一本体部1411为平面状，且第一本体部1411靠近电连接部142的边缘以及靠近第二本体部的边缘为弧线，第二本体部1412为贴合底座13外壁面的弧形面状，电连接部142沿第一本体部1411靠近电连接部142的边缘间隔分布，或均匀分布于该边缘弧线上。通过设置多个电连接部142可使得导电元件与位于发热体11上的电极12的 接触点增多，以保证发热体11在底座13内发生周向偏移时也可与电连接部142有效接触，以实现二者的有效电连接。在本实施例中，导电元件14包括一个本体部141和两个电连接部142。具体的，电连接部142与本体部141可一体成型，以便于生产，且能够保证导电元件14的整体结构不易受到破坏。
请再次参见图3，底座13的外侧壁形成有卡接槽132，导电元件14的第二本体部1412卡接于该卡接槽内，以对导电元件14在底座13的周向上进行限位，使得导电元件14与底座13在其周向方向上相对固定，从而使得在发热体11插接于底座13时，导电元件14的电连接部142与电极12实现对位连接，以保证加热线路的正确性。具体的，第二本体部1412靠近第一本体部1411的部分的周向尺寸大于第二本体部1412远离第一本体部1411的部分的周向尺寸，即，第二本体部1412在底座13上与第一本体部1411连接的一端的周向长度大于与电源耦接的一端的周向长度，一方面保证了第二本体部1412与第一本体部1411连接的可靠性，另一方面，还可减少第二本体部1412在底座13上所占的面积；底座13上的卡接槽132与第二本体部1412的形状及大小匹配，对应的，还可减小卡接槽132在底座13上所占的面积，从而为底座13上的其他结构预留足够的空间，有利于底座13的结构设计。第二本体部1412的具体形状和大小可根据实际需求进行设置，本申请对此并不加以限制。例如，在本实施例中，第二本体部呈规则的T型，既能满足上述条件，实现上述效果，而且还方便生产。
在另一实施例中，底座13的外侧壁上具有凸起，导电元件14的第二本体部1412上对应具有开口，以在导电元件14安装于底座13上时，底座13上的凸起卡接于第二本体部1412上的开口；容易理解，为了使导电元件14与底座13的装配更为可靠，第二本体部1412的上的开口和底座13上达到凸起可以设置为多个。当然，导电元件14与底座13的装配方式还可以是其他方式，对此本申请不作具体限定。
请参见图3和图6，其中，图6为图2的B-B向的剖视图；在该实施例提供的加热组件10中，还包括密封件15，该密封件15设置于底座 13与发热体11的端部之间，用于密封底座13与发热体11的端部之间的间隙。如图6所示，底座13的限位腔131内具有环形部133，环形部133与底座13的侧壁连接形成环形限位槽1331，发热体11插接于该环形限位槽1331内；密封件15设置于该环形限位槽1331内，以填充环形限位槽1331与发热体11插入部分之间的空隙，从而避免发热体11在插接于底座13后发生晃动。如图3所示，密封件15呈环形，其形状及大小与环形限位槽1331相匹配。具体的，密封件15可为具有弹性且耐高温的材质，比如橡胶或者胶水。
请参见图3和图7，图7为本申请一实施例提供的底座与固定座的结构示意图；本实施例提供的加热组件10，该加热组件10还包括固定座16，该固定座16套设与底座13的外侧，并与底座13连接；具体的，固定座16包括环形本体161和连接于环形本体161外侧的环形延伸部162，其中环形本体161的内侧圆半径小于环形延伸部162的内侧圆半径，如图6所示，固定座16的环形本体161朝向发热体11的方向延伸，环形延伸部162沿发热体11插入底座13的插接方向A延伸。具体的，固定座16的环形延伸部162上具有开口，固定座16上具有凸起，固定座16套设与底座13上时，固定座16的凸起卡接于环形延伸部162的开口，从而使得固定座16与底座13连接；一般地，凸起与开口为多个，以使得固定座16与底座13的连接更为可靠。
其中，如图6所示，导电元件14的本体部141夹持于固定座16与底座13之间，具体的，第一本体部1411夹持于固定座16的环形本体161与底座13的端部面之间，从而对本体部141进行限位，使得导电元件14固定于底座13与固定座16之间，避免导电元件14发生偏移。
进一步地，导电元件14的第二本体部1412包括夹持部1412a和耦接部1412b；其中，夹持部1412a连接于第一本体部1411远离电连接部142的一端，且夹持部1412a夹持于固定座16的环形延伸部162与底座13的环形侧壁之间；耦接部1412b连接于夹持部1412a远离第一本体部1411的一端，且耦接部1412b沿底座13的轴向方向延伸至固定座16外，即第二本体部1412的耦接部1412b暴露于固定座外，以与电源耦接； 具体地，耦接部1412b可通过导电件与电源耦接；该种与电源的耦接方式，无需在底座13或固定座16上设置孔洞或开口，以使电源组件20的导电件伸入，从而使得电源与导电元件14耦接，该实施例中导电元件14与电源的耦接方式更为简单，可减少制备步骤，有利于投入批量生产。当然，也可通过在固定座16上开孔或在底座13上开孔的方式使本体部141的部分暴露，以使电源组件20的导电件从开孔处伸入，从而使得电源与导电元件14耦接。在具体实施例中，夹持部1412a与耦接部1412b可一体成型，或者，导电元件14整体为一体成型结构，以便于生产，且能够保证导电元件14的整体结构不易受到破坏。
请继续参见图7，固定座16还包括设置于环形本体161上的第一限位结构163，该第一限位结构从环形本体161朝向固定座16的中心位置延伸，以对插入底座13内的发热体11进行径向限位，避免发热体11在径向上发生偏移导致电极12与导电元件14的连接发生断路或短路等问题。进一步地，第一限位结构163的数量至少为三个，且至少三个第一限位结构163沿环形本体161的周向均匀分布，以对插入底座13内的发热体11进行周向限位，避免其发生偏心现象。第一限位结构163的具体形状及大小可根据实际需求进行设置即可，只要能对插入底座13内的发热体11进行径向和周向限位，且不影响其他结构即可，对此不做具体限定。
具体地，固定座16还包括第二限位结构164，第二限位结构164设置于固定座16的环形延伸部162的内侧壁上，第二限位结构164用于与底座13的侧壁面抵接，以对底座13进行径向限位。具体的，第二限位结构164为限位凸筋，且沿固定座16的轴向方向延伸，从而在固定座16套接于底座13时，限位凸筋与底座13的侧壁面抵接，以对底座13进行径向限位。进一步地，底座13的侧壁的外壁面对应第二限位结构164的位置设置有限位凹槽134，限位凹槽134随限位凸筋沿固定座16的轴向方向延伸，从而在固定座16套接于底座13时，限位凸筋沿该限位凹槽134进入，使得第二限位结构164卡接于限位凹槽134内，即二者相匹配，以对底座13的周向进行限位，使得固定座16与底座13 在周向上相对固定。
以上所述仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
