如图1所示，本实用新型一实施例提供了一种雾化装置(图未示)，包括主机身、雾化芯100以及电源，雾化芯100和电源均收容于主机身内，电源用于为雾化芯100供电，雾化芯100用于储存并在电源电能作用上加热气溶胶生成基质，以使气溶胶基质产生气溶胶供使用者吸食。
请参阅图1及图2，雾化芯100包括基体120和发热层140。基体120大致呈圆柱状结构，基体120的中心轴线沿第一方向延伸，包括沿第一方向间隔设置的第一端面和第二端面以及连接第一端面和第二端面的侧壁。基体120的中心位置开设有雾化孔，雾化孔自基体120的第一端面沿第一方向延伸至基体120的第二端面，且雾化孔的中心轴线与基体120的中心轴线重合。发热层140围绕雾化孔的中心轴线卷绕于雾化孔内，并覆盖雾化孔的孔壁。如此，基体120可吸收雾化液导至发热层140，发热层140可加热雾化液以产生气溶胶。
进一步地，雾化孔的孔壁凸设有隔离部121，隔离部121沿第一方向自基体120的第一端面延伸至基体120的第二端面，且隔离部121位于发热层140在自身卷绕方向上的首尾两端之间，因此发热层140和隔离部121共同界定形成沿第一方向延伸的雾化通道160。也就是说，发热层140在第一端面所在平面上的正投影呈具有缺口的非封闭圆环形，该非封闭圆环形的缺口部分被隔离部121填充，发热层140的内表面和隔离部121的内表面在第一端面所在平面上的正投影呈完整的圆形。
如此，发热层140位于中空的基体120的内壁表面，气溶胶生成基质于基体120的内壁表面雾化，具有较高的热效率。与此同时，由于发热层140采用了非整圈环绕式结构，发热层140在自身卷绕方向上的首尾两端被隔离部121阻隔而无法接触，从而防止因发热层140的首尾两端重叠造成发热层140的发热线路开路等可靠性问题，进而降低了发热层140的布线难度和雾化芯100的生产工艺要求。
具体地在一些实施例中，基体120为由多孔陶瓷材料形成的多孔结构，多孔陶瓷是以刚玉砂、碳化硅、堇青石等优质原料为主料、经过成型和特殊高温烧结工艺制备的一种具有开孔孔径、高开口气孔率的一种多孔材料、具有耐高温，高压、抗酸、碱和有机介质腐蚀、良好的生物惰性、可控的孔结构及高的开口孔隙率、使用寿命长、产品再生性能好等特点。可以理解，基体120所采用的材料不限于此，可根据需要设置以满足不同要求。
具体地在一些实施例中，发热层140包括固定层141与发热膜层143，固定层141结合于雾化孔的孔壁并与隔离部121对应连接，发热膜层143结合于固定层141远离基体120的一侧表面。如此，固定层141用于对发热膜层143起到承载、固定的作用，发热膜层143通过固定层141固定于雾化孔内。
进一步地在一些实施例中，固定层141为由多孔陶瓷材料形成的多孔结构。可以理解，固定层141所采用的材料不限于此，可根据需要设置以满足不同要求。
上述雾化芯100的成型方式如下：
首先，通过流延成型工艺形成带状的固定层141，且固定层141由与基体120相同的多孔陶瓷材料形成。
然后，通过用物理气相沉积、气相反应、电镀、电沉积、离子镀或者喷涂金属材料等方式在固定层141的一侧表面形成发热膜层143，固定层141和发热膜层143共同构成发热层140。
最后，卷绕发热层140，并通过注塑工艺形成在发热层140外形成基体120。
上述雾化芯100，由于采用单层非整圈卷绕的方式形成发热层140，因此可防止发热膜的两端相互接触而出现开路等可靠性问题。相反，如果发热层140为多圈卷绕设计，那么必然存在重叠区域而形成具有厚度差的台阶。一旦台阶位置存在发热膜层143，则会存在开路的风险。而如果不在台阶位置设置发热膜层143而避免开路风险，则需要对发热膜层143进行精确的对位，从而增大了卷绕难度，不利于工业生产，同时严格的对位液会导致发热膜层143的形成区域被限制，从而影响发热膜层143的布线选择。
而且，发热层140的多圈卷绕将导致流延生带和基体120、相邻固定层141间结合不紧密，从而导致流延生带发生卷曲，进而导致流延生带上的发热膜不规整，最终影响雾化液的加热效果而影响雾化器的抽吸口感。
本申请还提供一种雾化组件，雾化组件包括上述雾化芯100及用于电连接雾化芯100和电源的电连接件。
电连接件设于基体120在第一方向上的至少一端并电连接于雾化芯100的发热层140，且电连接件开设有连通雾化通道160的通气孔。如此，电连接件用于电连接发热层140与电源以为发热层140供电，通气孔的设置使电连接件在实现电连接的同时不会影响气溶胶从雾化通道160中流出。
结合图3所示，本申请的第一实施例的一种雾化组件200，雾化组件200包括两个构造大致相同的电连接件210，两个电连接件210的一端分别插设于雾化通道160在第一方向上的相对两端并分别与发热层140电连接，两个电连接件210的另一端伸出雾化通道160以分别与电源电连接。
具体地，每个电连接件210呈开设有通气孔212的中空回转体状结构，每个电连接件210包括相互连接的第一连接端214和第二连接端216，第一连接端214的外径与雾化通道160的内径的大小相匹配，第二连接端216的外径大于第一连接端214的外径。如此，第一连接端214沿第一方向插设于雾化通道160在第一方向上的一端，且第一连接端214的外侧壁与发热膜层143接触以与发热膜层143电连接。第二连接端216连接第一连接端214的一侧端面抵持于基体120的第一端面或第二端面，第二连接端216远离第一连接端214的端面与电源通过面接触或点接触的方式电连接。
因此，雾化芯100在第一方向上的相对两端通过两个电连接件210分别连接电源的正极和负极。
结合图4所示，本申请的第二实施例的一种雾化组件300，该雾化组件300包括一个电连接件310，该电连接件310的一端插设于雾化通道160在第一方向上的一端，并同时连接发热层140的正极和负极，电连接件310的另一端伸出雾化通道160以与电源电连接。作为一种较佳的实施方式，电连接件310位于雾化通道160的进气端，从而可方便地与位于雾化通道160的进气端一侧的电源连接。
进一步地，第二实施例中的电连接件310的外轮廓形状与第一实施例的电连接件210的外轮廓形状大致相同，电连接件310呈开设有通气孔312的中空回转体状结构，电连接件310也包括相互连接的第一连接端和第二连接端，第一连接端的外径与雾化通道160的内径的大小相匹配，第二连接端的外径大于第一连接端的外径。
与第一实施例的电连接件210的不同之处在于，第二实施例的电连接件310包括正极连接部314、负极连接部316以及绝缘部318。正极连接部314和负极连接部316沿垂直于第一方向的方向相对设置，绝缘部318连接于正极连接部314和负极连接部316之间以使正极连接部314和负极连接部316相互绝缘，正极连接部314和负极连接部316的侧壁分别接触发热膜层143以分别电连接于发热膜层143的正极和负极。
如此，在第二实施例中，通过一个电连接件310即可将发热膜层143的正极与负极同时和电源电连接，从而进一步简化了雾化芯100的装配工艺。
如图5所示，在其它一些实施例的雾化组件中，雾化芯100还包括端部电极180，端部电极180至少部分覆盖雾化芯100在第一方向上的至少一端的端面并电连接于发热膜层143。如此，电连接件可直接抵持于端部电极180并与端部电极180电连接，而无需插设于雾化通道160中，从而进一步降低了雾化组件的加工难度，简化了雾化组件的装配工艺。
结合图6所示，本实用新型的第三实施例的一种雾化组件400，该雾化组件400的雾化芯100在第一方向上的两端均设有端部电极180，且端部电极180覆盖雾化芯100的端面。雾化组件400包括两个电连接件410，每个电连接件410呈开设有通气孔412的中空圆柱状结构，且电连接件410的外径的尺寸与基体120的外径的尺寸相匹配。
如此，两个电连接件410分别抵持于基体120两端的端部电极180并与端部电极180电连接，因此发热膜层143通过端部电极180和电连接件410分别连接发热层140的正极和负极。
结合图7所示，本实用新型的第四实施例的一种雾化组件500，该雾化组件500的雾化芯100在第一方向上的其中一端设有端部电极180，且端部电极180包括在垂直于第一方向上的方向上间隔设置的端部电极正极和端部电极负极。作为一种较佳的实施方式，端部电极180位于雾化通道160的进气端。雾化组件500包括一个电连接件510，该电连接件510抵持 于端部电极180并同时连接端部电极180的端部电极正极和端部电极负极。
具体地，电连接件510的外轮廓的形状与第三实施例的电连接件410的外轮廓的形状相同，呈开设有通气孔512的中空圆柱状结构，与第三实施例的电连接件410的不同在于，雾化组件500的电连接件510包括正极连接部514、负极连接部516以及绝缘部518。具体地，正极连接部514和负极连接部516沿垂直于第一方向的方向相对设置，绝缘部518连接于正极连接部514和负极连接部516之以使正极连接部514和负极连接部516相互绝缘，正极连接部514和负极连接部516分别再端部电极180上的正投影分别位于端部电极正极和端部电极负极的区域内，从而分别电连接于端部电极正极和端部电极负极。
如此，在第四实施例中，通过一个电连接件510即可将发热膜层143的正极与负极同时和电源电连接，从而进一步简化了雾化组件500的装配工艺。
上述雾化芯100、雾化组件及雾化装置，雾化芯100的基体120可与气溶胶生成基质直接接触而无需包覆储油棉，从而避免了包棉工序引起的产品稳定性、一致性较差的问题，同时防止了储油棉对导油效果的影响，避免了出现焦糊味等问题。而且，雾化芯100具有较高的可靠性，且加工方式简单，有利于雾化芯100的批量化生产。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
