参阅图1，本实用新型一实施例中，提供一种加热器件，加热器件应用于电子雾化装置200中，可用于加热雾化花叶类、草本类或膏类的气溶胶生成基质。
加热器件100包括基座10、线圈30和感应体50，基座10上形成有容置腔11，感应体50至少部分伸入容置腔11内，线圈30设置于基座10上并围绕伸入容置腔11内的感应体50。其中，线圈具有第一工作状态；在第一工作状态时，线圈30产生触发感应体50发热的电磁场，同时线圈30自身发热并热传导至基座10。
基座10上的容置腔11，用于容置气溶胶生成基质。线圈30处于第一工作状态时，线圈30通电与感应体50之间产生电磁感应现象，使容置腔11内的感应体50通过线圈30的电磁感应作用发热，从容置腔11内部对气溶胶生成基质进行加热。同时，线圈30通电后线圈30本身发热，且将热量传递给承载线圈30的基座10，使基座10发热，如此还可通过基座10从容置腔11的外周加热气溶胶生成基质。相当于，通过电磁感应利用感应体50从容置腔11内部加热气溶胶生成基质，同时还可通过线圈30本身产生的热量，来加热基座10，进而从容置腔11的外周加热气溶胶生成基质，使气溶胶生成基质的内外侧被同时烘烤，对气溶胶生成基质形成中心+外周的加热方式，以更加均匀地加热气溶胶生产基质，防止气溶胶生产基质被局部烘烤过度，更加均匀地进行雾化，提高用户使用口感。另外，从内外两侧可有效烘烤气溶胶生成基质，提高单个气溶胶生成基质的利用率及抽吸次数，防治气溶胶生成基质被浪费。
可选地，感应体50包括由强导磁性材料制成的感应部，当线圈30处于第一工作状态时，由强导磁性材料制成的感应部能够受到线圈30的磁感应作用而发热。具体地，强导磁性材料为镍基合金或者4系列不锈钢(例如，430不锈钢)。进一步地，基座10包括底壁12和侧壁14，底壁12和侧壁14相交连接并围合形成容置腔11，线圈30绕设于侧壁14的外表面上，以在线圈30通电后加热基座10的侧壁14，主要从容置腔11的外周侧来加热容置腔11内的气溶胶生成基质。这样，形成中心+外周加热的方式，能够均匀有效地进行烘烤。一些实施例中，线圈30具有第二工作状态；在第二工作状态时，线圈30仅自身发热并热传导至基座10。相当于，在第二工作状态时，线圈30不产生电磁感应作用，感应体50不会通过电磁感应被加热，只通过线圈30自身产生的热量加热基座10，进而仅从外侧加热容置腔11内的电容胶生成基质300，以满足雾化需求较小的应用场景。如此， 加热器件100具有通过内外两侧加热的加热方式，和仅从外侧加热的加热方式，在实际使用过程中，用户可以根据需求自由选择切换线圈的工作状态，便可切换加热器件的加热方式，提供丰富使用体验。
进一步地，在第一工作状态时，线圈30受控通高频电流，线圈30形成电磁感应作用，感应体50通过电磁感应发热，从中心加热气溶胶生成基质。同时，线圈30本身产生的热量传递给基座10，基座10从外围加热气溶胶生成基质。在第二工作状态时，线圈30受控通直流电，通直流电的线圈30无法形成电磁感应作用，感应体50无法发热，仅通过线圈30自身传递给基座10的热量，从外围加热气溶胶生成基质。如此，通过切换控制电路为线圈30的供电类型，便可切换加热器件100的工作状态。
具体地，上述任一实施例中，线圈30的电阻为0.008ohm-0.012ohm，可以在线圈30通电后产生足够的热量来加热气溶胶生成基质。可选地，线圈30的电阻为0.01ohm。
一些实施例中，基座10的材质为陶瓷或者耐高温材料，能够较好的传导线圈30产生的热量，且不容易因为受热损坏。
另一些实施例中，基座10包括金属本体和绝缘层，金属本体被构造形成容置腔11，绝缘层包裹于金属本体外，线圈30设于绝缘层上。线圈30通电产生的热量可传递至金属本体，金属本体具有较好的导热率，可将较多的热量传递给容置腔11内的气溶胶生成基质，具有较佳的烘烤效果。
进一步地，金属本体为弱导磁性金属，金属本体仅用于传导线圈30产生的热量，其为若磁性材料，不会与线圈30产生电磁感应，或在电场内的感应加热可以忽略不计。例如，金属本体的材质为铝、铜、304不锈钢、310不锈钢或316不锈钢。可选地，绝缘层的材质为陶瓷，具有较高的导热性，且不会在高温下受损。
一些实施例中，线圈30为金属薄膜线圈，金属薄膜线圈为薄膜状金属层。这样，在装配过程中，只需将金属薄膜线圈30贴附在基座10外表面上，便可使金属薄膜线圈30与基座10紧密贴合，进而可将金属薄膜线圈30产生的热量高效传导至基座10及内部的气溶胶生成基质中。可选地，金属薄膜线圈30所采用的薄膜材质包括铜箔、铝箔、银箔等导电性良好的金属材质。
另一些实施例中，线圈30通过电镀或丝印工艺附着于基座10上。如此，在基座10上附着线圈30，使线圈30与基座10一体化设置，线圈30产生的热量可以直接传递给基座10，线圈30产生的热量传导效率较高，并且线圈30集成一体化设置后加热装置100体积更小。
可以理解地，又一些实施例中，线圈30为普通的励磁线圈30，直接饶设在基座10上， 直接绕设的线圈30能够与感应体50之间产生电磁感应，还能够发热向基座10传导热量。
上述加热器件100具有以下优点：
(1)加热器件100具有从内外两侧加热气溶胶生成基质的加热方式，具体利用线圈30与感应体50之间形成电磁感应，使感应体50发热从气溶胶生成基质的内部进行加热，同时线圈30本身通电后发热，并将产生的热量传递给基座10从气溶胶生成基质的外侧进行加热。如此，可以更加均匀地烘烤气溶胶生成基质，并且可防止气溶胶生成基质浪费。
(2)加热器件100还具有仅从外侧加热气溶胶生成基质的加热方式，可为用户提供多种加热方式，丰富用户的使用体验。
(3)线圈30可以设置为励磁线圈30或者金属薄膜线圈30，线圈30还可通过电镀或者丝印设置在基座10上，可使线圈30与基座10紧密贴合，一方面满足产品小型化的需求，另一方便可将线圈30产生的热量有效传递给基座10，提高导热率。
基于同样的构思，本实用新型一实施例中，还提供一种电子雾化装置200，包括上述加热器件100。电子雾化装置200工作时，外界空气被抽吸进入容置腔11，与容置腔11内雾化形成的气溶胶混合，之后混合有气溶胶的空气便可供给用户使用。具体地，电子雾化装置200还包括外壳210和电芯230，加热器件100及电芯230均装配于外壳210内，电芯230用于为加热器件100供电。
进一步地，加热器件100还包括隔热层，隔热层包覆在线圈30外，以防止线圈30自身产生的热量向基座10以外的其他部件传递，防止电子雾化装置200的正常使用受到影响。
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。
