请一并参阅图1至图3，现对本实用新型实施例提供的吸液发热件进行说明。本实用新型实施例提供的吸液发热件适用于气溶胶发生装置的雾化器，雾化器通过该吸液发热件将气溶胶形成基质雾化形成烟雾，以供用户吸食而达到模拟吸烟的效果。请结合参阅图1和图2，本实用新型实施例提供的吸液发热件包括第一陶瓷基体1和加热元件3，第一陶瓷基体1均呈板片状结构设置，第一陶瓷基体1的形状可以是但不限于圆形、椭圆形、矩形、菱形、梯形或异型等形状。第一陶瓷基体1内部具有第一微孔结构，第一微孔结构可以将雾化器之储液件中的气溶胶形成基质吸附并存储于第一陶瓷基体1内部，且由存储于第一陶瓷基体1内部的气溶胶形成基质雾化形成的烟雾，可通过第一微孔结构传输至第一陶瓷基体1的至少部分外表面，第一陶瓷基体1的至少部分外表面形成第一雾化面11，并从第一陶瓷基体1的至少部分外表面流出。也就是说，第一陶瓷基体1的至少部分外表面包括第一陶瓷基体1的第一雾化面11(第一陶瓷基体1背离加热元件3的一面)和第一陶瓷基体1的其他侧面，烟雾可以由第一陶瓷基体1的第一雾化面11流出，烟雾也可以第一陶瓷基体1的其他侧面流出。加热元件3包括设置于第一陶瓷基体1与第二陶瓷基体2之间的发热线路32，发热线路32包括由若干第一弧形线3211路呈同心圆弧排布的第一发热结构321，以及由若干第二弧形线路3221呈同心圆弧排布的第二发热结构322，且第一发热结构321与第二发热结构322对称设置。
本实用新型实施例提供的吸液发热件在使用时，利用第一微孔结构将气溶胶形成基质吸附并存储于第一陶瓷基体1内部，设置于第一陶瓷基体1上的发 热线路32，在通电后产生热量，便可对吸附存储于第一陶瓷基体1内部的气溶胶形成基质进行加热，以使气溶胶形成基质雾化形成供用户模拟吸烟使用的烟雾。这样，利用第一微孔结构吸附和存储气溶胶形成基质，气溶胶形成基质可均匀地分散于第一陶瓷基体1内部。同时，呈同心圆弧排布设置的发热线路32在通电后产生的热量，由第一陶瓷基体1分散且均匀地传递至第一陶瓷基体1，使得吸液发热件上的温度分布均匀，进而使得气溶胶形成基质均匀受热，提高雾化效率和雾化效果。
本实用新型实施例提供的吸液发热件，与现有技术相比，通过在内部具有第一微孔结构的第一陶瓷基体1上设有发热线路32，发热线路32包括由若干第一弧形线路3211呈同心圆弧排布构成的第一发热结构321，以及由若干第二弧形线路3221呈同心圆弧排布构成的第二发热结构322，且第一发热结构321与第二发热结构322对称设置。则在使用时，仅需利用第一微孔结构吸附和存储气溶胶形成基质，便可使得气溶胶形成基质均匀地分散于第一陶瓷基体1内部。这样，呈同心圆弧排布设置的发热线路32在通电后产生的热量均匀地传递至第一陶瓷基体1，使得吸液发热件上的温度分布均匀，进而使得气溶胶形成基质均匀受热，提高雾化效率和雾化效果。
请结合参阅图2，在其中一些实施例中，第一发热结构321还包括第一连接线路3212和第一电极3213，第一连接线路3212将相邻第一弧形线3211路电性相连，第一电极3213与位于第一发热结构321最外侧的第一弧形线3211路电性相连，第二发热结构322还包括第二连接线路3222和第二电极3223，第二连接线路3222将相邻第二弧形线路3221相连的第二连接线路3222，第二电极3223与位于第二发热结构322最外侧的第二弧形线路3221电性相连。位于第一发热结构321最内侧的第一弧形线路3211与位于第二发热结构322最内侧的第二弧形线路3221电性相连。通过上述结构设置，将发热线路32形成一个大致呈同心圆环排布的整体，有利于发热线路32的温度均匀分布。并且，发热线路32设置第一电极3213与第二电极3223，以作为引线进行内部电路的导 通，方便发热线路32与电源装置的电性连接。
请结合参阅图2，在其中一些实施例中，相邻第一弧形线3211路之间的间距相等，相邻第二弧形线路3221之间的间距相等，一方面可确保金属发热线路32的发热有效面积更大，提高发热效率，另一方面可使得金属发热线路32通电后产生的热量均匀分布，从而使得吸液发热件温度分布更加均匀，进而有利于气溶胶形成基质的均匀受热。
请结合参阅图1，在其中一些实施例中，吸液发热件还包括与第一陶瓷基体1叠置的第二陶瓷基体2，第二陶瓷基体2内部具有吸附并存储气溶胶形成基质的第二微孔结构，由气溶胶形成基质雾化形成的烟雾可通过第二微孔结构传输至第二陶瓷基体2的至少部分外表面，加热元件3夹设于第一陶瓷基体1与第二陶瓷基体之间。具体地，第二陶瓷基体2内部具有第二微孔结构，第二微孔结构可以将雾化器之储液件中的气溶胶形成基质吸附并存储于第二陶瓷基体2内部，且由存储于第二陶瓷基体2内部的气溶胶形成基质雾化形成的烟雾，可通过第二微孔结构传输至第二陶瓷基体2的至少部分外表面，第二陶瓷基体2的至少部分外表面形成第二雾化面21，并从第二陶瓷基体2的至少部分外表面流出。也就是说，第二陶瓷基体2的至少部分外表面包括第二陶瓷基体2的第二雾化面21(第二陶瓷基体2背离加热元件3的一面)和第二陶瓷基体2的其他侧面。烟雾可以由第二陶瓷基体2的第二雾化面21流出，烟雾也可以第二陶瓷基体2的其他侧面流出。加热元件3包括夹设于第一陶瓷基体1与第二陶瓷基体2之间的发热线路32，发热线路32包括由若干第一弧形线321路呈同心圆弧排布的第一发热结构321，以及由若干第二弧形线路3221呈同心圆弧排布的第二发热结构322，且第一发热结构321与第二发热结构322对称设置。在使用时，利用第一微孔结构将气溶胶形成基质吸附并存储于第一陶瓷基体1内部，利用第二微孔结构将气溶胶形成基质吸附并存储于第二陶瓷基体2内部，位于第一陶瓷基体1与第二陶瓷基体2之间的发热线路32，在通电后产生热量，便可对吸附存储于第一陶瓷基体1与第二陶瓷基体2内部的气溶胶形成基质进 行加热，以使气溶胶形成基质雾化形成供用户模拟吸烟使用的烟雾。这样，利用第一微孔结构和第二微孔结构吸附和存储气溶胶形成基质，气溶胶形成基质可分别均匀地分散于第一陶瓷基体1与第二陶瓷基体2内部。同时，呈同心圆弧排布设置的发热线路32在通电后产生的热量，由第一陶瓷基体1与第二陶瓷基体2中间分别分散且均匀地传递至第一陶瓷基体1与第二陶瓷基体2，使得吸液发热件上的温度分布均匀，进而使得气溶胶形成基质均匀受热，提高雾化效率和雾化效果。
在其中一些实施例中，加热元件3还包括夹设于第一陶瓷基体1与第二陶瓷基体2之间的陶瓷片31，发热线路32为印刷或喷涂于陶瓷片31上的金属发热层。该实施例中，通过采用上述方案，通过在陶瓷片31表面设置金属发热线路32，金属发热线路32在陶瓷片31表面形成通电后发热的发热层。这样，设有金属发热线路32的陶瓷片31便可构成加热元件3。可以理解地，金属发热线路32可以采用包括但不限于印刷或喷涂的方式形成于陶瓷片31的表面。在其中一些实施例中，金属发热线路32可以为通过薄膜方式形成于陶瓷片31表面的金属薄膜，金属薄膜的厚度为1nm～100um。金属薄膜可以是但不限于铜、镍、珀、铝、金等金属薄膜，金属薄膜也可以是不锈钢或镍络合金等其他具备导电性金属氧化物、或者其它导电性材料薄膜。
请结合参阅图1和图3，在其中一些实施例中，陶瓷片31表面围绕金属发热线路32凸设有环形封边311，在陶瓷片夹设于第一陶瓷基体1与第二陶瓷基体2之间时，环形封边311可将金属发热线路32封装于吸液发热件中，防止金属发热线路32暴露而发生氧化。
可以理解地，在其中一些实施例中，陶瓷片31采用包括但不限于氮化铝、碳化硅、氧化铝等材料制成的陶瓷片31，陶瓷片31采用流延/凝胶成型的方式制作所需陶瓷层的生瓷带，生瓷带的厚度为0.3mm～5mm。陶瓷片31采用流延/凝胶成型制作的生瓷带，方便裁剪出所需要的形状与尺寸，生瓷带的形状包括但不限于正方体、长方体、菱形体、梯形体、多边形体或异形体。并且，在其 中另一些实施例中，陶瓷片31构成夹设于第一陶瓷基体1与第二陶瓷基体2之间的第三陶瓷基体，第三陶瓷基体与第一陶瓷基体1、第二陶瓷基体2分别采用平面固定结合的方式。其中，平面固定结合的方式包括但不限于烧结或平面粘合的方式。可以理解地，在其中一些实施例中，第一陶瓷基体1、第二陶瓷基体2与第三陶瓷基体的形状与大小可以一致，第一陶瓷基体1、第二陶瓷基体2与第三陶瓷基体的形状与大小也可以不一致。当第一陶瓷基体1、第二陶瓷基体2与第三陶瓷基体的形状与大小一致时，有利于进一步增强吸液发热件整体结构的一致性。
可以理解地，在其中一些实施例中，第一陶瓷基体1和第二陶瓷基体2采用包括但不限于氧化铝、硅藻土、堇青石、莫来石、氧化锆、氧化硅等材料制成的陶瓷片，第一陶瓷基体1的厚度为0.1mm～5mm，第二陶瓷基体2的厚度为0.1mm～5mm，第一陶瓷基体1与第二陶瓷基体2的厚度可以相同也可以不同。第一微孔结构的孔径范围控制在5μm～200μm之间，第二微孔结构的孔径范围控制在为5μm～200μm之间，既保证第一微孔结构、第二微孔结构具有良好的储液能力，又可使得烟雾能够分别通过第一微孔结构、第二微孔结构传输至第一陶瓷基体1的第一雾化面11、第二陶瓷基体2的第二雾化面21。
