具体地，第一导电件32包括相互连接的第一传导部321和第二传导部323，第二传导部323沿与第一传导部321延伸方向相交的方向凸出设置于第一传导部321上，半导体陶瓷层包裹覆盖第二传导部323的外周，以在第二传导部323上烧结半导体陶瓷层。并且，沿与第一传导部321延伸方向相交的方向凸出设置第二传导部323，在与第一传导部321延伸方向相交的方向上，第二传导部323为电极30的最远端，覆盖于第二传导部323上 的半导体陶瓷层也为最远端，相邻两个电极30之间两个半导体陶瓷层之间的距离最短能够放电产生电弧，通过耐热性较好的半导体陶瓷层承受高温弧斑，防止电极30被烧蚀，提高电极30的使用寿命。
一些实施例中，壳体组件10包括外壳12和内锅14，内锅14可拆卸地设于外壳12上，且内锅14和外壳12之间界定形成加热腔20，内锅14具有容置腔141，电极30设于外壳12上且部分伸入加热腔20。如此，通过外壳12固定安装电极30，内锅14的容置腔141用于放置气溶胶生成基质，当需要加热雾化气溶胶生成基质时，控制电极30在加热腔20内放电产生电弧，进而形成等离子体来加热内锅14及内锅14中的气溶胶生成基质。并且，将内锅14可拆卸设置，在使用一段时间后方便拆卸清理内锅14，保证雾化口感。
本申请一实施例中，还提供一种上述任一实施例所述的电极30。电极30包括第一导电件32和第二导电件34，第二导电件34设于第一导电件32自身延伸方向的一端用于放电，且第二导电件34的耐热性大于第一导电件32的耐热性。也就是说，将电极30分为两部分，位于端部用于放电的第二导电件34耐热性较强，不容易被高温电弧烧蚀或氧化，这样通过局部增大电极30的耐热性及耐烧蚀能力，进而提高电极30的使用寿命。可以理解地，第一导电件32被构造为长条状，用于与供电电路电连接，第一导电件32的延伸方向为其纵长方向。
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。
