 背景技术
如图1所示，相关技术的雾化组件40通常包括吸液棉412以及绕设于该吸液面412上的发热元件42。当该吸液棉412吸液时，吸液棉412的表面上会形成油膜A，吸液棉412吸液后膨胀，外凸明显，从而使得吸液棉412上的油膜A厚度增加，油膜A高出发热元件42外表面，当用户抽吸时，电子雾化装置的液体向吸液棉412补给，由于油膜A内外侧温差较大，会出现炸油现象，不仅导致电子雾化装置中的部件被污染，而且影响用户体验感。
目前烧结式雾化组件被广泛用于电子雾化装置中，以解决上述问题。如图2所示，雾化组件40一般包括硬质的吸液体及设置吸液体的发热元件42，该硬质的吸液体可以为烧结式多孔体411。目前的有些发热元件42是通过冲压或激光切割等工艺形成的片状结构，发热元件42设置于烧结式多孔体411的一个表面上，发热元件42与烧结式多孔体411通过烧结的方式一体成型。由于烧结式多孔体411的表面张力，烧结式多孔体411的表面也会形成油膜A，由于烧结式多孔体411不易变形，因为油膜A厚度在吸液前后均不变，且厚度比较低，一般小于发热元件42的厚度，当用户抽吸时，电子雾化装置的液体向吸液棉412补给，油膜A内外温度相差较小，进而不会出现炸油现象。
 技术问题
但是，由于在烧结成型过程中，烧结式多孔体411会在高温烧结过程中，蒸发掉造孔剂等材料，以及本身会有化学反应等综合原因，导致烧结式多孔体411会有较大收缩，从而容易出现成型的烧结式多孔体411上发热元件42会有部分相对于烧结式多孔体411表面翘起的现象，或者与烧结式多孔体411之间存在间隙B，参见图3。发热元件翘42起部分或者存在间隙B部分由于不与烧结式多孔体411接触，在发热元件42加热过程中，烟液难以到达发热元件42翘起部分上，导致翘起部分干烧，浪费能量同时会产生焦味等问题。

进一步地，在本实施例中，在本实施例中，该发热体42可设置于该复合式吸液结构41上，且沿该第一吸液体411的长度方向设置，其分别与该第一雾化面4113和第二雾化面4123接触。该发热体42在一些实施例中，可由不锈钢、镍铬合金、铁铬铝合金、金属钛等制成。
在本实施例中，该发热体42可与该第一吸液体411一体成型。具体地，该发热体42可通过烧结的方式与该多孔体411一体成型。进一步地，以第一吸液体411为陶瓷多孔体为例，可以先用高岭土泥团形成第一吸液体411的坯体，再将该发热体42贴设于该坯体一端或者埋设于该坯体中，再将坯体烘干、烧结即可。可以理解地，在其他一些实施例中，该发热体42与该第一吸液体411可以为分体结构，不限于一体成型。

如图10所示，当储液腔中的烟液向第二吸液体412补给，因该第二吸液体412变形量大于该第一吸液体411的变形量，该第一雾化面4113会凸出该第二雾化面4123设置，从而可填充该发热部421与该第一吸液体411之间的间隙，并使得该第二雾化面4123上形成的油膜的厚度大于该第一雾化面4113上形成的油膜的厚度，该第二雾化面4123上的油膜中的油会向该第一雾化面4113上的油膜流动，进而可以平衡该第一雾化面4113和该第二雾化面4123之间油膜的厚度，从而可防止炸油、以及防止设置于其上的发热体干烧，减少能量浪费，避免焦味产生，并可提高锁液效果、换气效果、提高用户体验感。
图11及图12示出了本发明电子雾化装置的第二实施例，其与该第一实施例的区别在于，该复合式吸液结构41可呈柱状，该发热体42可呈螺旋状。第一吸液体411和该第二吸液体412可以呈柱状，该第二吸液体412可套设于该第一吸液体411的外周。该第二吸液面4124可形成于该第二吸液体412的外周面。

图15及图16示出了本发明电子雾化装置的第三实施例，其与该第一实施例的区别在于，该通孔4111可以为多个，该多个通孔4111可间隔设置，且分别沿该第一吸液体411的厚度方向贯穿该第一吸液体411设置。该插接部4122可以为多个，其与该通孔4111一一对应设置，其可一一对应插设于该通孔4111中，且每个插接部4122可以呈柱状。每个插接部4122的横截面形状以及尺寸与该发热体42的弯折部4212内侧形状以及尺寸相适配。
进一步地，在本实施例中，该发热部421整体以宽度方向嵌设于该复合式吸液结构41中，该发热部421的顶面与该第一雾化面4223齐平，该发热部421的宽度方向可与该第一雾化面4113所在的平面大致垂直，一方面可以使得烟液在第一吸液体复合式吸液结构41流动更加流畅，另一方面可便于制作，降低制成成本。并且，将该发热部421整体以宽度方向嵌设于该复合式吸液结构41中，可以使得该发热部421的大部分表面均与该复合式吸液结构41接触，进而可提高雾化效率，减少热量损失，防止干烧或大大减少干烧效果。可以理解地，在其他一些实施例中，该发热部421也可以部分嵌设于该复合式吸液结构41中，且其顶面可以凸出该第一雾化面4113。在其他一些实施例中，其顶面也可以低于该第一雾化面4113。
进一步地，在本实施例中， 该发热部421均与该第二吸液体412和该第一吸液体411接触。具体地，该弯曲部4212的内表面可与该第二吸液体412接触。该弯曲部4212的外表面可与该第一吸液体411接触。当该第一吸液体411烧结收缩时，因该第二吸液体412的存在，该发热部421可避免因间隙的存在而无法与烟液接触进而导致干烧。
在本实施例中，该两个导电连接部422可呈柱状，其可位于该发热部421的两端，且分别一体连接于该发热421的两端，其可分别沿该复合式吸液结构41的两相对设置的侧壁穿出设置，以与该供电装置200电连接。
可以理解的，以上实施例仅表达了本发明的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制；应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，可以对上述技术特点进行自由组合，还可以做出若干变形和改进，这些都属于本发明的保护范围；因此，凡跟本发明权利要求范围所做的等同变换与修饰，均应属于本发明权利要求的涵盖范围。
