具体的，第一底座141及第二底座142形成的底座14包括靠近用于卡合线路板13的第一部分148及连接于第一部分148一端且用于卡接固定件的第二部分149。第一部分148与第二部分149均为圆形，其中，线路板13卡合在第一部分148的位置处，具体的，第一部分148的内侧具有与线路板13厚度对应的 卡轨171，线路板13嵌入于所述卡轨171中，为了防止线路板13在卡轨171中移动，卡轨171对应线路板13的缺口135的位置处具有卡柱(图未示)，卡柱自线路板13的缺口135的位置处自一面贯穿至另一面，以将线路板13固定在卡轨171中。在一实施例中，卡柱从卡轨171内延伸至第一部分148远离第二部分149的一侧，并在第一部分148的下端形成凸起172。第二部分149的外径小于第一部分148的外径，其中，第二部分149的外侧设置有至少一个凸起146，第二部分149的外侧还设置有与第一部分148垂直且平齐的卡轴147。
在一实施例中，加热装置还包括套筒16，套筒16与底座14配合。具体的，套筒16中空结构，套筒16一端具有与套合部152形状对应的安装孔161，在套筒16与底座14配合时，安装孔161套设在套合部152外侧，套筒16远离发热线路111的一端与第一部分148抵接。具体的，为了使套筒16与底座14紧密结合，套筒16内壁对应底座14外侧的凸起146的位置处具有卡接口163，对应底座14外侧的卡轴147的位置处具有第二卡槽162，套筒16在套设在底座14的外侧后，凸起146与卡接口163卡合，卡轴147与第二卡槽162配合，具体的，在一实施例中，在将套筒16套设在底座14的外侧时，卡轴147在第二卡槽162的表面沿与底座14及套筒16的轴向平行的方向移动，进而将套筒16与底座14固定。可以理解的，套筒16的外径与第一部分148的外径匹配，以此在将套筒16与底座14配合后，套筒16与底座14外表面平齐。本实施方式中，套筒为圆柱形，安装孔161一端向圆形套筒16的中心位置形成凸缘164，凸缘164抵压于密封件15的抵靠部153上并与套合部152平齐。
在一实施例中，线路板13还包括第三电极133及第四电极134，第三电极133及第四电极134用于连接主电路板，用以对加热装置进行供电。具体的，在第三电极133及第四电极134还连接第一连接端子113及第二连接端子114，用于检测第一连接端子113及第二连接端子114之间的电压。
在另一实施例中，如图2所示，线路板的第一电极131及第二电极132为一对电极，分别为正电极及负电极，第三电极133及第四电极134为一对电极，分别为正电极及负电极。其两对电极均与加热元件11上的第一连接端子113及第二连接端子114连接。其中，在第一电极131及第二电极132、第三电极133及第四电极134均与第一连接端子113及第二连接端子114连接，其中，第一电极131及第二电极132向加热元件11提供大电流，进而对发热线路111进行 加热，第三电极133及第四电极134提供小电流，用于在加热过程中检测第一连接端子113及第二连接端子114之间的电压，从而控制加热的温度。由于两对电极都与主板电路接触，因此会产生接触电阻。如果线路板13上只有一对电极(第一电极131及第二电极132)时，由于电流过大，其通过接触电阻产生的压降会很大，因此使得检测到的第一连接端子113及第二连接端子114之间的电压不够准确，所以设置第三电极133及第四电极134提供小电流来检测第一连接端子113及第二连接端子114之间的电压。
在另一实施例中，线路板13还包括存储芯片(图未示)，存储芯片用于存储加热过程中产生的数据。此时，线路板13上包括连接存储芯片的存储接口，该控制接口共用第一电极131及第二电极132、第三电极133及第四电极134与第一连接端子113及第二连接端子114连接，进而获取到加热元件11在加热过程中产生的数据。在另一实施例中，主电路板可以通过读取存储芯片上存储的数据进而通过第一电极131及第二电极132控制发热元件11，以使其发热。
在一实施例中，本申请提供的加热装置及加热元件在工作时，发热线路111所在的第一区域的温度T1与导电线路112所在的第二区域的温度T2的关系为(T1-T环)/(T2-T环)<2，其中，T1的温度区间在100～500摄氏度；T2温度区间在250～T环摄氏度，T环表示为标准气压下的温度。在一具体实施例中，标准气压下为298.15K，其对应的温度为25℃，即T环＝25℃。
本发明提供的加热装置包括加热元件及固定加热元件的固定座，本发明通过将固定座与加热元件的接触位置设置在加热元件的发热线路位置处，以此能够有更多的区域设置固定座，提高加热元件的固定牢固性。另外为了防止发热线路的温度过高对固定座造成损坏，本发明将与发热线路接触的固定件的材料选为陶瓷材料，在另一实施例中，固定座的材料还可以是压铸铝合金、压铸锌合金，或者还可以是耐高温高分子材料如聚苯并咪唑(PBI)、高温尼龙(LCP)。
请参见图4，为本发明雾化装置的一实施例的结构示意图。电子雾化装置包括供电装置32及加热装置31，其中供电装置32用于给加热装置31供电，加热装置31为上述图1及图2、图3所述的加热装置，具体结构与图1及图2、图3所示相同，在此不再赘述。
在一具体实施方式中，本发明提供的电子雾化装置可应用于加热不燃烧型电子雾化装置，例如烟具。在一具体实施方式中，本发明提供的电子雾化装置 可应用于雾化吸入治疗行业，雾化吸入治疗是通过不同的装置把药物以气溶胶的形式输出并随呼吸进入体内。气溶胶是指固体微粒或液体微粒混悬于空气或空气中组成的分散体系，可以随空气流动传输。在雾化吸入治疗中，选择合适的装置及正确的吸入方法对治疗效果有很大影响。本发明提供的雾化装置具体可应用于如定量压力气雾剂、干粉吸入剂、喷射雾化器等设备。
以上仅为本发明的实施方式，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。
