其中，调味材料收容部5与壳体1连接，且在调味材料收容部5上设有收容腔52，调味材料设于收容腔52，以便于对调味材料进行固定。
如图1和图3所示，图3是图1中的口味弹的立体结构示意图。口味弹10设于收容腔52内，口味弹10朝向气流连通通道9的一端设有阻隔网12，阻隔网12用于将调味材料限制于口味弹10内。
在另一实施例中，阻隔网12也可以根据需要设置在其它的位置处，例如直接设置在调味材料收容部5底部，以便于直接将调味材料设置于收容腔52内，本发明实施例不做具体限定。
其中，在一实施例中，阻隔网12和调味材料收容部5可以设置为一体结构，例如，可以通过注塑的方式将阻隔网12和调味材料收容部5一体注塑成型。在另一实施例中，阻隔网12和调味材料收容部5还可以分别设置为两个单独的元件，并将阻隔网12与调味材料收容部5可拆卸连接，或者通过焊接、螺纹连接的方式进行连接，本发明实施例对阻隔网12和调味材料收容部5的连接方式不做具体限定。
可选地，如图1所示，电子雾化装置100包括调味材料加热元件51，调味材料加热元件51与调味材料接触，用于加热雾化调味材料。通过设置用于对调味材料进行加热的调味材料加热元件51，可以进一步提升调味材料的温度，使得调味材料内的成分充分释放出来，以进一步提升雾化气的口感。
其中，调味材料加热元件51可以与调味材料直接接触，或者，调味材料加热元件51也可以与调味材料间接接触。
在一实施例中，调味材料加热元件51设于收容腔52的内侧壁，并环绕收容腔52的周向设置。
具体地，调味材料加热元件51呈连续环形设置于收容腔52的内侧壁，以使得位于收容腔52内的调味材料受热均匀。
可选地，调味材料加热元件51的数量还可以设置为多个，多个调味材料加热元件51环绕收容腔52的内侧壁均匀间隔设置。
在一实施例中，若将调味材料直接设置于收容腔52内，可以使得调味材料与调味材料加热元件51直接接触，进而提升调味材料加热元件51与调味材料的热传导效率，并可以降低调味材料加热元件51的热量传输损失。
在另一实施例中，若将口味弹10设置于收容腔52内，则可以将调味材料加热元件51与调味材料间隔开，以便于保护调味材料加热元件51，避免调味材料与调味材料加热元件51直接接触而在调味材料加热元件51的表面附着较多的灰垢，降低调味材料加热元件51的加热效率，浪费电能。
其中，调味材料加热元件51的加热温度为60-65℃，以使得调味材料的成分缓慢挥发。
其中，在一实施例中，雾化单元4可以和壳体1可拆卸连接。具体地，如图1所示，雾化单元4包括储液腔42、首次加热元件41和雾化气通道43。储液腔42储存常温下液态的气溶胶生成基质。首次加热元件41将液态的气溶胶生成基质加热雾化，雾化气沿雾化气通道43流动到气流连通通道9。通 过将雾化单元4与壳体1可拆卸连接，可以便于在储液腔42内的气溶胶生成基质使用完时，对雾化单元4进行更换。
或者，在另一实施例中，雾化单元也可以固定设置于壳体内，例如，可以利用壳体形成用于存储气溶胶生成基质的储液腔，以简化电子雾化装置的结构，缩小电子雾化装置的体积。
二次加热元件7位于调味材料收容部5与雾化气通道43之间的气流连通通道9。
具体地，电子雾化装置100包括连接件11，连接件11设于雾化单元4和调味材料收容部5之间，气流连通通道9设于连接件11上，气流连通通道9连通雾化气通道43和收容腔52，二次加热元件7设于气流连通通道9内。
在一实施例中，雾化气通道43、气流连通通道9和收容腔52依次对接，以形成封闭的传输通道，避免雾化气在电子雾化装置100的内部发生泄露。
在另一实施例中，还可以根据需要在雾化气通道43、气流连通通道9和收容腔52之间设置其它的通道或者元件，本发明实施例不做具体限定。
其中，在垂直于气流连通通道9的传输方向上，雾化气通道43的横截面尺寸、气流连通通道9的横截面尺寸以及收容腔52的横截面尺寸可以相等也可以不等，本发明实施例不做具体限定。
在一实施例中，如图1所示，气流连通通道9的传输方向为图中所示的D方向，雾化气通道43的横截面的形状和尺寸与气流连通通道9的横截面的形状和尺寸大致相同，以增强雾化气通道43与气流连通通道9连接处的气密性。收容腔52的横截面尺寸大于气流连通通道9的横截面尺寸，以降低雾化气在收容腔52中的传输速率，进而延长雾化气与调味材料的接触时间和接触面积，以使得调味材料内的成分充分释放至雾化气中。
在本实施例中，为了更充分加热雾化气，气流连通通道9设有一个空间扩大部91，二次加热元件7位于空间扩大部91。
具体地，如图1所示，在垂直于气流连通通道9的传输方向上，空间扩大部91的横截面尺寸大于与空间扩大部91邻接的其它部分的横截面尺寸，二次加热元件7设于空间扩大部91内。当雾化气传输至空间扩大部91的位置处时，由于空间扩大部91的横截面尺寸变大，使得雾化气的传输速率降低。将二次加热元件7设于空间扩大部91内，可以延长雾化气与二次加热元件7接触的时间，进而使得雾化气的加热更加充分，以获得温度更高，颗粒更小的雾化气。
在一实施例中，空间扩大部91设于气流连通通道9的中部，在垂直于气流连通通道9的传输方向上，空间扩大部91的横截面尺寸大于气流连通通道9与雾化气通道43连接一端的横截面尺寸，并大于气流连通通道9与收容腔52连接一端的横截面尺寸，以形成中部大、两端小的气流连通通道9。通过在气流连通通道9的中部设置空间扩大部91，一方面可以便于气流连通通道9与雾化气通道43对接连通，另一方面也可以便于设置收容腔52的横截面尺寸大于气流连通通道9的横截面尺寸。
在另一实施例中，也可以将空间扩大部91设于气流连通通道9与雾化气通道43连接的一侧。或者，在又一实施例中，也可以将空间扩大部91设于气流连通通道9与收容腔52连接的一侧，本发明实施例对空间扩大部91的设置位置不做具体限定，可以根据需要灵活设置。
二次加热元件7可以为网状、螺旋盘状电阻加热片，也可以是螺旋发热丝。在本施例中，二次加热元件7为网状加热片，与气流方向垂直。
具体地，如图1和图4所示，图4是图1中的二次加热元件的立体结构示意图。二次加热元件7为网状的电阻加热片，网状的电阻加热片覆盖在气流连通通道9内。通过设置网状的电阻加热片，可以提升二次加热元件7与雾化气的接触面积，并可以使得雾化气受热均匀。进一步地，电阻加热片所在的平面与气流连通通道9的传输方向D垂直。通过此种设置方式，可以简 化电阻加热片的固定结构，并且可以缩小电阻加热片的体积。
在另一实施例中，还可以设置电阻加热片所在的平面相对气流连通通道9的传输方向D倾斜，以增大位于气流连通通道9内的电阻加热片的面积，进而增大电阻加热片与雾化气的接触面积，以进一步提升雾化气的温度。
在又一实施例中，电阻加热片还可以设置为螺旋盘状，且电阻加热片所在的平面与气流连通通道9的传输方向D垂直。或者，二次加热元件7还可以为螺旋发热丝，螺旋发热丝沿气流连通通道9的传输方向D延伸设置。或者，在其它可选地实施例中，还可以采用其它形状的二次加热元件7，且二次加热元件7的设置位置可以根据需要灵活设置，本发明实施例不做具体限定。
二次加热后的雾气可以更好的带走烟草的香味。优选地，二次加热后的雾化气温度控制在60-100摄氏度范围内；更优选地，二次加热后的雾化气温度控制在60-85摄氏度范围内。调味材料收容部5的温度优选控制在60-65摄氏度范围内。
其中，二次加热元件7的加热温度为60-100℃，以使得被二次加热元件7加热后的雾化气的温度为60-100℃。通过控制加热后的雾化气的温度为60-100℃，一方面可以使得调味材料内的成分挥发，另一方面也可以避免雾化气的温度过高使得调味材料产生焦味，影响口感。
进一步地，如图1和图5所示，图5是图1中的局部放大结构示意图。电子雾化装置100包括抽吸感应组件，抽吸感应组件用于感应抽吸作用力，以用于判断用户是否在使用电子雾化装置100。当抽吸感应组件感应到用户在抽吸电子雾化装置100时，抽吸感应组件产生感应信号，电路板3接收感应信号后，进一步控制雾化单元4开始雾化气溶胶生成基质。
其中，如图1和图5所示，抽吸感应组件包括气流传感器气流通道81和气流传感器8。气流传感器气流通道81连通气流连通通道9和气流传感器8，气流传感器8用于检测气流连通通道9内的压力变化。即气流传感器气流通 道81一端与气流连通通道9连接，一端通向气流传感器8。当用户抽吸时，气流传感器8将感应到的信号传递到控制电路3，控制电路3启动首次加热元件41加热雾化。
具体地，当抽吸作用力作用于电子雾化装置100时，会使得气流连通通道9内的压力发生变化，气流传感器气流通道81与气流连通通道9连通，气流连通通道9内的压力变化引起气流传感器气流通道81内的压力变化，气流传感器8感应到气流传感器气流通道81内的压力变化时产生感应信号。
可选地，气流传感器8设置在雾化单元4和电源2的上方，这样可以避免被雾化单元4的漏液污染，以保护气流传感器8，提升气流传感器8的检测精度。
具体地，如图1所示，电源2和雾化单元4并排设置，以使得电子雾化装置100的结构更加紧凑。气流传感器8设于电源2的上方，以避免抽吸感应组件与气流连通通道9产生干涉。
图6是本发明一个实施例的电路示意图110。首次加热电路111、二次加热电路112和调味材料加热电路113为并联的独立控制电路。气流传感器8的抽吸信号和按压部12的按压信号传递到电路板3，电路板3上的控制电路按照预设的策略控制加热电路111、二次加热电路112和调味材料加热电路113。
一种电子雾化装置的加热控制方法，其步骤包括：
当接收到抽吸信号时，启动首次加热元件加热雾化单元的储液形成雾化气；
判断用户选择二次加热的模式，决定是否启动二次加热元件加热，其中，二次加热元件设置在位于调味材料和雾化单元的气流连通通道。
具体地，请参阅图7，图7是本发明一实施例中的加热控制方法的流程示意图。本发明另一方面还提供一种加热控制方法，该加热控制方法应用于上述的电子雾化装置100，现结合图1至图6对本实施例中的加热控制方法进行 详细说明。具体地，加热控制方法包括以下步骤：
步骤S101：当接收到抽吸信号时，启动雾化单元的首次加热元件加热气溶胶生成基质形成雾化气。
具体地，设置在电子雾化装置100内的抽吸感应组件用于感应用户的抽吸作用力，当用户抽吸使用电子雾化装置100时，抽吸感应组件产生抽吸信号，电路板3接收抽吸信号并控制雾化单元4的首次加热元件41工作以加热雾化气溶胶生成基质形成雾化气。
或者，在其它可选地实施例中，还可以在电子雾化装置100上设置开关按钮，以通过按压开关按钮产生启动信号，以用于控制雾化单元4的首次加热元件41工作以加热雾化气溶胶生成基质形成雾化气，本发明实施例对首次加热元件41的启动方式不做具体限定。
步骤S102：判断用户是否选择二次加热。
具体地，电子雾化装置100判断用户是否选择二次加热。
步骤S103：若用户选择二次加热，则启动二次加热元件加热雾化气；其中，二次加热元件设置在位于调味材料和雾化单元之间的气流连通通道内。
具体地，若电子雾化装置100判断出用户选择二次加热，则控制电源2向二次加热元件7供电，以启动二次加热元件7加热雾化气。将调味材料设置于电子雾化装置100的气流连通通道9内，以使得二次加热元件7再次加热后的雾化气流经调味材料后排出电子雾化装置100，供用户吸取。如此，温度较高的雾化气经过调味材料后，可以使得调味材料内的成分充分释放，进而与气溶胶生成基质雾化产生的雾化气一起排出，供使用者吸取，如此可以提升电子雾化装置100的口感，提升用户的使用体验。
若电子雾化装置100判断出用户未选择二次加热，则断开二次加热元件7。
其中，请参阅图8，图8是图7中的步骤S102的流程示意图。判断用户是否选择二次加热的步骤具体包括：
步骤S201：判断是否接收到按压信号。
其中，用户可以通过按压设置于壳体1上的按压部12以触发开关6产生按压信号。当按压部被按压时，产生按压信号，电路板接收按压信号。当按压部未被按压时，不产生按压信号，电路板不会产生按压信号。
步骤S202：判断二次加热元件是否启动。
具体地，电子雾化装置100检测二次加热元件7是否加热，若电子雾化装置100检测到二次加热元件7处于加热状态，则二次加热元件7启动，若电子雾化装置100检测到二次加热元件7处于非加热状态，则二次加热元件7没有启动。
步骤S203：若接收到按压信号，且二次加热元件未启动，或者若未接收到按压信号，且二次加热元件启动，则判断出用户选择二次加热。
若在步骤S101中，接收到抽吸信号时，不仅启动了首次加热元件41，还同时启动了二次加热元件7，则在首次加热元件41雾化气溶胶生成基质之时，二次加热元件7同时对雾化形成的雾化气再次进行加热。此时，若电子雾化装置100未接收到按压信号，并判断出二次加热元件7已启动，则判断出用户选择二次加热，此时二次加热元件7持续加热雾化气。若电子雾化装置100接收到按压信号，并判断出二次加热元件7已启动，则判断出用户取消二次加热，此时电源2停止向二次加热元件7供电，以停止加热。
若在步骤S101中，接收到抽吸信号时，仅启动了首次加热元件41，并未启动二次加热元件7。此时，若电子雾化装置100未接收到按压信号，并判断出二次加热元件7未启动，则判断出用户未选择二次加热，二次加热元件7不加热。若电子雾化装置100接收到按压信号，并判断出二次加热元件7未启动，则判断出用户选择二次加热，此时二次加热元件7持续加热雾化气。
进一步地，启动二次加热元件7加热雾化气的步骤包括：控制二次加热元件7再次加热雾化气以使得加热后的雾化气的温度为60-100℃。通过控制 加热后的雾化气的温度为60-100℃，一方面可以使得调味材料内的成分挥发，另一方面也可以避免雾化气的温度过高使得调味材料产生焦味，影响口感。
其中，在一实施例中，可以设置二次加热元件7的加热温度为60-85℃。
请参阅图9，图9是本发明另一实施例中的加热控制方法的流程示意图。在本实施例中，加热控制方法包括以下步骤：
步骤S301：当接收到抽吸信号时，启动雾化单元的首次加热元件加热气溶胶生成基质形成雾化气。
步骤S302：判断用户是否选择二次加热。
步骤S303：若用户选择二次加热，则启动二次加热元件加热雾化气；其中，二次加热元件设置在位于调味材料和雾化单元之间的气流连通通道内。
其中，步骤S301至步骤S303与上述实施例中的步骤S101至步骤S103相同，请参照上述实施例中的描述，此处不再赘述。
步骤S304：响应于开关控制信号，控制调味材料加热元件加热雾化调味材料。
可选地，在一实施例中，开关控制信号和按压信号可以均通过按压部12进行触发。具体地，用户可以通过按压设置于壳体1上的按压部12以同时触发开关6产生开关控制信号和按压信号。此时，开关6将调味材料加热元件51与电路板3电连接，电路板3将调味材料加热元件51与电源2电连接，进而控制调味材料加热元件51加热雾化调味材料，以进一步提升调味材料的温度，便于调味材料内的成分充分挥发。
或者，在另一实施例中，开关控制信号和按压信号也可以通过不同的按压部进行触发，以便于单独控制二次加热元件7和调味材料加热元件51。
进一步地，控制调味材料加热元件51加热雾化调味材料的步骤包括：控制调味材料加热元件51加热雾化调味材料的温度为60-65℃。
综上所述，本领域技术人员容易理解，本发明实施例通过在气流连通通 道9内设置二次加热元件7，并使得二次加热元件7位于雾化单元4与调味材料收容部5之间，雾化单元4雾化产生的雾化气经气流连通通道9传输，在进入调味材料收容部5之前，二次加热元件7可对冷却后的雾化气再次进行加热，如此，不仅可以对雾化气中冷凝形成的大液滴进行再次加热以形成小液滴雾化气，还可以提升进入调味材料收容部5内的雾化气的温度，以使得调味材料内的成分充分释放，进而与气溶胶生成基质雾化形成的雾化气一起排出，供使用者吸取，如此可以提升电子雾化装置100的口感，并提升用户的使用体验。
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它相关的技术领域，均同理包括在本发明的专利保护范围内。
