在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
参见图1，图1是本申请提供的气溶胶生成装置一实施例的结构示意图。气溶胶生成装置100可用于加热雾化气溶胶生成基质10。其可用于不同的领域，比如，医疗雾化、美容雾化和休闲吸食领域等。具体的，气溶胶生成装置100是一种用于通过加热但不使气溶胶生成基质(经过处理的植物叶类制品)燃烧的电子设备。气溶胶生成装置100通过高温加热到气溶胶生成基质10可以产生气溶胶但是却不足以燃烧的温度，能在不燃烧的前提下，让气溶胶生成基质10产生用户所需要的气溶胶。
其中，气溶胶生成装置100包括壳体101和设置在壳体101内的加热组件20和电源组件30。加热组件20用于加热雾化气溶胶生成基质10以形成气溶胶，电源组件30包括电池31、气流传感器(图未示)以及控制线路板(图未示)等；电源组件30用于为加热组件20供电并控制加热组件20工作，以加热雾化气溶胶生成基质10形成气溶胶。其中，气流传感器用于检测气溶胶生成装置100中气流变化，控制线路板根据气流传感器检测到的气流变化启动电池31为加热组件20供电。在另一可选实施方式中，也可以没有气流传感器，控制线路板根据控制信号启动电池31为加热组件20供电。
本申请发明人发现，现有的采用周圈加热的加热组件中，加热元件与磁场发生器之间通过空气或者隔离材料隔离，然而，加热组件在加热气溶胶生成基质的过程中，加热元件的热量可以通过空气或是隔离材料传导到磁场发生器上，导致磁场发生器温度过高，进而影响磁场发生器工作。另外，加热元件的热量散失较大，影响加热效率，增加了气溶胶 生成装置的功耗，还会导致气溶胶生成装置壳体温度过高，影响用户体验。
为此，本申请提供一种加热组件20，参见图2-图5，图2是如图1所示气溶胶生成装置中加热组件的一实施例的结构示意图；图3是如图2所示的加热组件沿A-A线的剖视图；图4是如图1所示气溶胶生成装置中加热组件的另一实施例的结构示意图；图5是如图4所示的加热组件沿A-A线的剖视图。
具体的，加热组件20包括内管21、外管22、加热元件23以及磁场发生器24。磁场发生器24用于在通电条件下产生电磁场，加热元件23位于电磁场内且在电磁场的作用下产生感应电流，从而产生感应热对气溶胶生成基质10进行加热。其中，外管22套设于内管21的外侧，且与内管21界定形成隔热腔201，隔热腔201内的气压小于外界大气压；加热元件23位于隔热腔201内且设置于内管21的外表面；磁场发生器24设置于外管22的外侧。具体的，通过设置隔热腔201内的气压小于外界大气压，加热元件23位于隔热腔201内且设置于内管21的外表面，使得加热元件23产生的热量能够通过内管21传递而不易传递至外管22，减少热量散失，从而降低功耗，提高雾化效率；且磁场发生器24设置于外管22的外侧，可以避免加热元件23产生的热量传递至磁场发生器24导致磁场发生器24温度过高，影响工作。
可以理解的，加热元件23的材料为能够在电磁场的作用下产生感应电流的材料，例如，加热元件23为铁磁性材料制成，如铁、镍、钴、不锈钢、铁铬钴，铝镍钴，钕铁硼等；或由混合有铁磁性材料的复合材料制成，如镍铬合金、铜铁合金、镍铬铁合金、铁铬铝合金等。其中，加热元件23可以直接固定设置于内管21的外表面；加热元件23也可以为内管21的外表面通过丝印、涂覆或沉积(物理气象沉积、化学气象沉积)的方式形成的金属膜。
本实施方式，内管21和外管22的材料为磁绝缘材料，如绝缘陶瓷或玻璃。具体的，磁场发生器24在通电状态下，内管21和外管22上不会产生感应电流，从而不会产生感应加热。从而避免外管22上产生 的热量传递到磁场发生器24和壳体101。气溶胶生成基质10只被加热元件23从内管21传递的热量进行加热。本实施例中，内管21和外管22具有良好的热稳定性和刚性，例如，以绝缘陶瓷制成的内管21和外管22的抗弯强度可在600MPa以上，热稳定性可超过450度，耐火性能可高于1450度，内管21的导热系数可为4-18W/(m.k)。
在另一实施方式中，外管22的材料为磁绝缘材料，内管21的材料为能够在电磁场的作用下产生感应电流的材料。具体的，磁场发生器24在通电状态下，外管22上不会产生感应电流，从而不会产生感应加热，加热元件23产生的感应加热和内管21上产生的感应加热共同对气溶胶生成基质10进行加热，从而提高加热雾化效率。
在一实施例中，磁场发生器24为能够产生电磁场的电子设备或电磁线圈。当磁场发生器24为电磁线圈时，电磁线圈旋绕外管22的外侧设置。电磁线圈能够在通电条件下产生电磁场，从而使得位于电磁场内的加热元件23产生感应加热。
在一实施例中，参见图2，电磁线圈包括间隔设置的第一电磁线圈241和第二电磁线圈242，第一电磁线圈241设置于外管22的第一端，第二电磁线圈242设置于外管22的第二端。第一电磁线圈241和第二电磁线圈242可以独立或同时进行工作，例如，根据用户需要，电源组件30可选择性地且独立地控制第一电磁线圈241和第二电磁线圈242工作，使得加热元件23的部分可以感应加热，另外部分由于不处于电磁场内从而不进行感应加热，从而有效控制雾化量。本实施例中，加热元件23为分段式设计，加热元件23包括间隔设置的第一子加热段231和第二子加热段232，第一子加热段231和第一电磁线圈241对应设置，以保证第一子加热元件231始终位于第一电磁线圈241所产生的电磁场内以产生感应电流；第二子加热段232和第二电磁线圈242对应设置，以保证第二子加热元件232始终位于第二电磁线圈242所产生的电磁场内以产生感应电流，保证雾化效果。当然，本实施例中，加热元件23也可以不采用分段式设计，只要保证加热元件23位于第一电磁线圈241和第二电磁线圈242所产生的电磁场内即可，在此不作限定。
在一实施例中，由于气溶胶生成基质10包含多种成分物质，不同成分物质的沸点温度不同，电源组件30也可以对第一电磁线圈241和第二电磁线圈242输出不同的功率，使得第一电磁线圈241和第二电磁线圈242产生不同的电磁场强度，进而使得位于不同电磁场强度内的加热元件23的感应加热所产生的热量不同，从而满足对气溶胶生成基质10内不同成分物质的差异化加热，提升雾化效果。
当然，电磁线圈的数量也可以为1个(参见图4)，或电磁线圈的数量也可以为大于两个。当电磁线圈的数量大于等于两个时，多个电磁线圈间隔设置，具体可根据实际情况进行选择，在此不做限定。其中，无论电磁线圈的数量为一个或多个，一个或多个电磁线圈在内管21的外表面的投影与加热元件23重叠，以保证加热元件23始终位于电磁线圈所产生的电磁场内，以保证对气溶胶生成基质10的加热雾化效果。
在一实施例中，电磁线圈的数量为多个且间隔设置，加热元件23包括多个间隔设置的子加热段，多个子加热段的数量与多个电磁线圈的数量相同，多个子加热段与多个电磁线圈一一对应设置。具体的，每个电磁线圈在内管21的外表面的投影与其对应设置的子加热段重叠，以使得每个子加热段位于与其对应设置的电磁线圈所产生的电磁场内。
在一实施例中，参见图2-图3，加热元件23与外管22间隔设置。具体的，外管22的两端形成缩口部221，外管22通过缩口部221与内管21连接，加热元件23的两端与缩口部221间隔设置，且加热元件23与外管22的其他部分均间隔设置，从而使得加热元件23产生感应加热时，加热元件23上的热量不会与外管22直接接触而将热量传递至外管22，避免将热量传递至电磁线圈和壳体101，导致电磁线圈温度过高，降低电磁线圈的工作效率，以及避免壳体101温度过高，影响用户使用体验。
在一实施例中，内管21至少部分延伸出外管22。参见图1-图3，内管21为中空柱状，用于容置气溶胶生成基质10，在气溶胶生成基质10容置于内管21时，气溶胶生成基质10的侧壁与内管21的内表面贴合，且气溶胶生成基质10至少部分延伸出内管21，可以增加与气溶胶 生成基质10的接触面积，从而增加对气溶胶生成基质10的加热雾化效果。
在另一实施例中，为简化工艺难度，参见图5，内管21的两端与外管22的两端平齐。
在一实施例中，参见图6-图8，图6是如图1所示气溶胶生成装置中加热组件的又一实施例的结构示意图；图7是如图6所示的加热组件沿A-A线的剖视图；图8是如图6所示的加热组件沿B-B线的剖视图。外管22的外表面还具有多个周向设置的支撑件222，电磁线圈旋绕外管22且设置于支撑件222上。具体的，通过在外管22的外表面沿外管22的周向设置多个支撑件222，每个支撑件222沿外管22的高度方向延伸，电磁线圈旋绕外管22且设置于支撑件222上，使得电磁线圈与外管22间隔设置，进一步避免了加热元件23上产生的热量传递至电磁线圈，保证电磁线圈正常工作。
在一具体实施方式中，每个支撑件222的一侧面可以均与外管22的外表面连接。在另一实施方式中，参见图7，每个支撑件222的两个端部与外管22的外表面连接，其余部分与外管22间隔设置。
上述各实施例中，加热组件20中的隔热腔201可以为真空隔热腔201。可以理解的，真空对热量的传导基本为零，通过将加热元件23设置于真空隔热腔201内且设置于内管21的外表面，加热元件23与外管22间隔设置，使得加热元件23上产生的热量只能通过内管21传递，而无法传递至外管22，从而减少加热元件23热量散失，降低气溶胶生成装置100的功耗，提高加热雾化效率，且同时可以避免加热元件23产生的热量传递至外管22的外侧的磁场发生器24和壳体101，导致磁场发生器24和壳体101温度过高，影响磁场发生器24工作以及用户使用体验的问题。
在一实施例中，气溶胶生成装置100还包括磁屏蔽层(图未示)，磁屏蔽层设置于磁场发生器24与外壳之间，用于对磁场发生器24产生的电磁场进行扭曲或屏蔽，以减小电磁场辐射至气溶胶生成装置100外，对用户产生不良影响。
以上所述仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请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，均同理包括在本申请的专利保护范围内。
