其中，以具有直线型微槽的加热件200为例。
需要注意的是，上述实施例中所述的加热件200可以部分嵌设在吸液体100的雾化面1001上，因此，当加热件200上的微槽2101为环形凹槽时，则微槽2101可以部分延伸到吸液体100内；而当加热件200上的微槽2101为非环形凹槽时，此时，微槽2101两端开设则可以对接在雾化面1001上或者至少部分延伸到吸液体100内。例如，如图9所示加热件200上的微槽部210内的微槽下端的开口可以对接于雾化面1001，或者微槽部210内的微槽可以部分插设到吸液体100。

此方案可以确保加热件200局部电阻变化不会过大，从而可以提高加热件200局部热流的均匀性，从而可以使得加热件200在加热雾化过程中不容易出现烧断。同时，通过将微槽2101的深度控制在5um-15um的范围内，可以使得雾化液雾化后形成的气泡脱离速度明显，从而到达控制在雾化过程中的沸腾特性，控制气溶胶形成的机制的效果。
本实施例中，微槽2101的宽度可以在5um-30um的范围内，微槽部210内可以开设多个平行且间隔设置的微槽2101，此时，每一微槽部210的宽度可以设置为微槽2101的宽度的3-5倍，且相邻的两个微槽部210之间的间距可以设置为微槽部210的宽度的5-8倍。
如上述实施例中所述，加热件200可以通过多次弯折后形成，在其他的实施方式中，加热件200还可以通过模具冲压、铸造、机械编织、化学蚀刻等一种或几种方式获得。
其中，加热件200可以采用一条金属丝或者金属片形成，或者，加热件200也可以采用至少两条金属丝或者金属片形成，具体的加热件200可以采用多个直径较小的金属丝或者金属片，经过卷绕或者粘接或者焊接的方式形成。
进一步的，请参阅图14-图15，图14是现有技术中的加热件的部分加热丝的结构示意图；图15是采用现有技术中的加热件进行加热雾化时的示意图。
其中，加热丝300表面平滑且未设置微槽结构；因此，在采用加热丝300对雾化液进行加热雾化时，雾化液雾化后形成的气泡体积差异较大，且气泡分布不均匀。
其中，如图16a-图16c所示，图16a-图16c是采用现有技术中的加热件进行加热雾化时雾化效果变化示意图。
其中，图16a-图16c分别为间隔1秒后的雾化效果变化示意图，其可以显示出采用现有技术中的加热件进行加热雾化时，形成的气泡位置随机性较大。
进一步的，请参阅图17-图19，图17是本申请提供的加热件的部分加热丝的结构示意图；图18是图17提供的加热丝的局部放大图；图19是采用本申请提供的加热件进行加热雾化时的示意图。
其中，采用本申请提供的加热件200进行加热雾化时，可以使得雾化后形成的气体在微槽2101的位置形成气泡，并且气泡逐渐长大后逐渐脱离微槽2101而释放出，其可以使得脱离微槽2101的气泡的位置固定，因此，在加热件200上设置多个间隔设置的微槽部210，可以使得释放出的气泡分布更加均匀；且， 由于气泡在微槽2101内更容易脱离雾化液的液膜表面，因此可以将气泡体积控制在一定的范围内，从而可以有效的实现雾化过程中的口感。
其中，如图20a-图20c所示，图20a-图20c是采用本申请提供的一种加热件进行加热雾化时雾化效果变化示意图。
同样的，图20a-图20c分别为间隔1秒后的雾化效果变化示意图。其可以显示出在加热件200上形成的雾化气泡，均可以在微槽部的位置形成，因此雾化气泡形成的位置稳定。
本实施例中，加热件200可以采用一根加热丝形成。
如图21a-图21c所示，图21a-图21c是采用本申请提供的另一种加热件进行加热雾化时雾化效果变化示意图。
同样的，图21a-图21c分别为间隔1秒后的雾化效果变化示意图。其可以显示出在加热件200上形成的雾化气泡，均可以在微槽部的位置形成，因此雾化气泡形成的位置稳定。
此方案与前文所述方案区别在于，本实施例中，加热件200可以采用两根加热丝形成，其中，两根加热丝可以并排设置。
进一步的，本申请还提供了一种雾化器。请参阅图22，图22是本申请提供的一种雾化器一实施例的结构示意图。
其中，雾化器40包括雾化套筒410、安装座420以及如前文所述的雾化芯10。其中，雾化套筒410内可以设置储液腔411及出气通路412，安装座420则盖设于雾化套筒410的开口处，安装座420可以用于固定安装雾化芯10。
其中，雾化芯10中的吸液体100的吸液面1002可以与储液腔411相连通，以使得的储液腔411中存储的雾化液可以进入吸液体100，雾化芯10的雾化面1001则可以与出气通路412相连通，从而使得雾化芯10对雾化液加热后形成的雾化汽可以从出气通路412中释放出。
进一步的，本申请还提供了一种电子雾化装置。请参阅图23，图23是本申请提供的一种电子雾化装置一实施例的结构示意图。
其中，电子雾化装置50可以包括如前文所述的雾化器40及本体组件510。
其中，雾化器40用于存储雾化液并雾化该雾化液以形成可供用户吸食的烟雾，本体组件510则可以包括电源组件，其电源组件可以与雾化器40中的加热件200电连接，以用于为加热件200供电。
综上，本领域技术人员容易理解，本申请的有益效果是：本申请通过在加热件上开设微槽，从而可以在加热件对雾化液进行加热雾化过程中，使得雾化液更容易形成汽化核心，增加雾化过程中沸腾气化核心，降低雾化过程中的热 流密度，从而使得汽化核心形成的气泡可以在微槽结构中脱离长大，并脱离雾化液的液膜表面，这样通过设置微槽可以控制在雾化过程中沸腾特性，控制气溶胶形成的机制(即，控制气溶胶形成的位置和气溶胶的尺寸)，从而可以有效的实现雾化过程中的口感。
以上所述仅为本申请的实施例，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它相关的技术领域，均同理包括在本申请的专利保护范围内。
