发热体20用于加热雾化烟液，为区别于发热丝的片状结构，其包括相对的第一表面和第二表面。发热体20以其第一表面与基体10相接触设置在基体20的导液口11上，可以最大限度覆盖在导液口11上，增大雾化面积。烟液可通过导液口11导流到发热体20上，经发热体20加热雾化形成烟雾。
在基体10上，发热体20的主体部位于导液口11处，至少两端位于导液口11外周的基体10的表面上。
发热体20呈片状（相对于网片为实心片体）或网片结构，可以是不锈钢、镍、钛、镍铬合金、铝或碳材料等制成；发热体20的外周形状可以是但不限于多边形、椭圆形、圆形等各种形状。

S3、往注塑模具300的基体模腔301内倒入基体料液，基体料液在基体模腔301内固化形成基体10，发热体20固定在基体10上。
S4、将带有基体10的发热体片材100从注塑模具300内取出。
S5、切割，排去发热体片材100的边框废料，使得发热体20从发热体片材100上分离，并与基体10形成雾化组件。
切割时，沿着发热体20与边框废料的连接线将发热体20从其上分离出来。切割采用激光切割、线切割、剪切等方式实现。
上述实施例的制备方法，主要采用模内注塑方式实现发热体20与基体10的固定，相比于热压方式两者固定更为牢固。该制备方法适用于单个雾化组件的生产，也适用多个雾化组件同时制得的批量化生产，效率高。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明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，均同理包括在本发明的专利保护范围内。
