请参阅图3和图4，图3为本申请第一实施例提供的加热组件的横向截面图；图4为本申请一实施例提供的加热组件的立体图；在第一实施例中，提供一种加热组件10。该加热组件10包括收容结构11、至少一个加热膜12和供电组件13。
其中，如图4所示，供电组件13包括第一电极131和第二电极132；至少一个加热膜12的两端分别第一电极131和第二电极132电连接，以通过该第一电极131和第二电极132同时向该至少一个加热膜12供电，以进行单端加热，即至少一个加热膜12共用第一电极131和第二电极132进行供电，至少一个加热膜12的供电功率相同。
供电组件13的第一电极131和第二电极132可位于收容结构11的同一端，并分别沿收容结构11的周向方向延伸。在具体实施例中，第一电极131和第二电极132具体可位于收容结构11背离近端开口的一端的端部；且第一电极131和第二电极132具体可采用银、金、铜以及含有金、银、和铜的合金等高导电率的金属材料。
如图3所示，收容结构11包括基体111和辐射层112。基体111为中空管状，且基体111具有收容腔110和与收容腔110连通的近端开口和远端开口，近端开口和远端开口沿基体111的长度方向C相对设置。收容腔110用于收容气溶胶生成制品2；气溶胶生成制品2具体通过近端开口沿收容腔110的长度方向C收容于收容腔110内或从收容腔110内移出。其中，近端开口为加热组件10靠近吸嘴的一端。具体的，基体111可为中空管状结构，该中空管状结构围设形成收容腔110。具体的，基体111的外径沿其长度方向C均一；基体111具体可为中空圆柱形。
具体的，基体111可采用绝缘材料制备，比如，基体111可以是石英管、陶瓷管或云母管等等。优选地，基体111可为透明石英管，以便于红外线穿过。当然，基体111也可以采用非绝缘材料制备，例如采用不锈钢、铝等金属制备。
辐射层112设置于基体111侧壁的内表面，用于在被加热时辐射红外线，以利用红外线加热并雾化收容于收容腔110内的气溶胶生成制品2。上述利用红外线加热气溶胶生成制品2，由于红外线具有一定的穿透性，不需要介质，加热效率较高，能够有效提高气溶胶生成制品2的预热效率，降低气溶胶生成制品2内外的温度差，从而使气溶胶生成制品2的烘烤更加均匀，避免出现局部高温导致气溶胶生成制品2被烧焦的问题。同时，通过将辐射层112设置于基体111的内表面，辐射层112辐射的红外线无需穿过基体111可直接辐射至气溶胶生成制品2，红外线的利用率较高。
其中，辐射层112具体可采用丝印、溅射、涂敷、印刷等方式形成于基体111侧壁的整个内表面。辐射层112具体可为红外层，红外层的材料包括钙钛矿体系、尖晶石体系、碳化物、硅化物、氮化物、氧化物以及稀土系材料等高红外发射率材料中的至少一种。
结合图3至图5，图5为图4的拆解示意图；加热膜12呈线状覆盖于收容结构11上。在一实施例中，至少一个加热膜12设置于基体111背离辐射层112的一侧，并沿收容结构11 的周向方向间隔设置于收容结构11的表面，用于在通电时产生热量，以加热辐射层112，使辐射层112被加热而辐射红外线。具体的，加热膜12使用通电释放焦耳热的电阻材料，如厚膜印刷电阻层、薄膜印刷电阻层或纳米电阻层等。
其中，如图3所示，在基体111为绝缘基体111时，加热膜12具体设置于基体111背离辐射层112的一侧表面，加热膜12产生的热量经基体111热传导至辐射层112以加热辐射层112。可以理解，在该实施例中，加热膜12直接设置于收容结构11的表面，即加热膜12与收容结构11的表面直接接触。在基体111为非绝缘基体111时，优选地，基体111为金属材料制成，例如采用不锈钢制成，如图6所示，图6为本申请一具体实施例提供的加热组件的横向截面图；基体111背离辐射层112的一侧表面还形成有耐高温的第一绝缘层113，加热膜12具体设置于第一绝缘层113背离基体111的一侧表面，以防止加热膜12与基体111之间短路；此时，加热膜12产生的热量依次经第一绝缘层113、基体111热传导至辐射层112以加热辐射层112。可以理解，在该实施例中，加热膜12通过第一绝缘层113设置于收容结构11上，即加热膜12与收容结构11的表面间接接触。在一个具体实施方式中，第一绝缘层113可以采用釉层。
在该实施例中，为了提高加热组件10的热量利用率，以进一步提高气溶胶生成制品2的加热效率；参阅图7，图7为本申请一实施例提供的气溶胶生成制品收容于收容结构内的结构简图；在气溶胶生成制品2收容于收容腔110内时，气溶胶生成制品2与收容结构11的侧壁的内表面(如辐射层112表面)直接接触。如此，在利用红外线辐射至气溶胶生成制品2的内部，以加热气溶胶生成制品2的同时，可同时通过收容结构11(如辐射层112)将加热膜12的热量传导至气溶胶生成制品2，以利用该热量进一步加热气溶胶生成制品2，提高了热量利用率，加快的雾化效率及气溶胶的生成速度。
当然，在其他实施例中，如图8所示，图8为本申请另一实施例提供的气溶胶生成制品收容于收容结构内的结构简图；在气溶胶生成制品2收容于收容腔110内时，气溶胶生成制品2也可与收容结构11的侧壁的内表面(如，辐射层112)间隔设置，以防止气溶胶生成制品2刮伤或蹭坏辐射层112的问题发生。可以理解，在该实施例中，气溶胶生成制品2主要通过红外线辐射加热。进一步的，加热膜12或/和辐射层112表面可以进一步涂覆保护层，保护层具体可以采用釉层。其中，辐射层112的厚度可以为10-100微米。优选地，辐射层112的厚度为20-40微米。在该实施方式中，辐射层112可采用厚膜印刷方式制作。辐射层112的材质可以包括黑硅、堇青石、过渡金属氧化物系列尖晶石、稀土氧化物、离子共掺杂钙钛矿、碳化硅、锆英石以及氮化硼中的一种或多种。当然，辐射层112的厚度还可以为1-10微米；优选地，辐射层112的厚度为1-5微米。在该实施方式中，辐射层112具体为薄膜镀膜。辐射层112材料可以为CrC、TiCN、类金刚石薄膜(DLC)。
结合图9，图9为图4所示加热膜和供电组件沿收容结构的周向方向展开的示意图；在一具体实施例中，加热膜12的数量为一，一个加热膜12包括并联的多条加热线121，多条 加热线121中至少两条加热线121并联在一起；且每一加热线121呈线条状；每一加热线121的至少部分沿收容结构11的长度方向C延伸。可以理解，线条状的加热线121其长度尺寸远远大于宽度尺寸。
具体的，如图9所示，多条加热线121中的至少部分加热线121为曲线。该曲线可为S型曲线。或者，如图10所示，图10为本申请另一实施例提供的加热膜12和供电组件13沿收容结构11的周向方向展开的示意图；该曲线还可以是U型曲线。当然，在其它具体实施例中，每一加热线121还可以是其它任意不规律弯曲的线条，比如，S型和U型组合的曲线；本申请对此并不加以限制。
在一具体实施例中，如图9所示，多条加热线121分别沿收容结构11的长度方向C延伸，且部分加热线121(以下称之为第一组加热线)的第一端与第一电极131电连接，第一组加热线中的每一加热线121的第二端与其余部分加热线121(以下称之为第二组加热线)的第二端电连接；第二组加热线中的每一加热线121的第一端与第二电极132电连接；以使第一组加热线中的多个加热线121并联在一起，第二组加热线中的多个加热线121并联在一起，然后使第一组加热线与第二组加热线串联在一起。
具体的，每一加热线121均为沿收容结构11的长度方向C延伸的S型曲线；当然，也可以是U型曲线。多条加热线121沿加热膜12的中轴线L可对称分布；且相邻两个加热线121沿这两个加热线121的中轴线对称分布。其中，中轴线L为加热膜12沿宽度方向D展开后的中轴线。
具体的，加热组件10还包括第一电连接部122、第二电连接部123以及第三电连接部124。第一电连接部122具体位于收容结构11靠近近端开口的一端，多条加热线121的第二端分别与第一电连接部122电连接，以通过该第一电连接部122实现多条加热线121的第二端的电连接，进而将第一组加热线和第二组加热线串联在一起。
第一组加热线中的多条加热线121的第一端分别与第二电连接部123电连接，以通过第二电连接部123与第一电极131电连接。第二组加热线中的多条加热线121的第一端分别与第三电连接部124电连接，以通过第三电连接部124与第二电极132电连接；从而通过第一电极131和第二电极132向该加热膜12供电。
具体的，该加热膜12包括第一加热线、第二加热线、第三加热线和第四加热线这四条加热线121。其中，第一加热线和第二加热线并联在第一电极131和第一电连接部122之间；第三加热线和第四加热线并联在第二电极132和第一电连接部122之间。即，该加热膜12中的四个加热线121先两两并联，再串联在一起。
在该具体实施例中，至少一个加热膜12被配置为，在收容结构11的长度方向C的中点两侧的功率密度不同。即，至少一个加热膜12产生的热量使收容结构11的收容腔110内的高温区域不位于收容腔110沿长度方向C的中心区域。这样能够按照预期设计收容结构11的温度场，便于设计其它非对称的高温区域位置。
具体的，如图4至图9所示，与收容结构11的长度方向C垂直且穿过中点的平面M将收容结构11的表面划分为第一区域A和第二区域B；第二区域B位于第一区域A背离近端开口的一侧。每一加热膜12的每一加热线121的部分位于第一区域A，其余部分位于第二区域B；且至少一个加热膜12在第一区域A内的单位面积的电阻密度与至少一个加热膜12在第二区域B内的单位面积的电阻密度不同。这样可以在至少一个加热膜12通电之后，使收容结构11的第一区域A的加热功率和第二区域B的加热功率存在差异，进而在收容结构11的第一区域A和第二区域B形成温度不同的两个区域。同时，上述以中线平面M为第一区域A和第二区域B的分割线，能够保证所形成的高温区域与收容腔110的长度方向C的中点偏置，便于设计其他非对称的高温区位置。
具体的，为了提高加热组件10靠近近端开口处的加热速度，以加快气溶胶的生成速度；可使至少一个加热膜12在第一区域A内的单位面积的电阻密度大于多个加热膜12在第二区域B内的单位面积的电阻密度；这样，由于第一区域A和第二区域B的加热膜12整体为串联关系，因此，至少一个加热膜12通电后，电阻密度较大的区域的功率密度较大，即，第一区域A的加热功率密度大于第二区域B的加热功率密度；相对应的，第一区域A的基体111内表面与加热膜12重叠的区域也大于第二区域B的辐射层112与加热膜12重叠的区域，以及第一区域A对应的辐射层112相较于第二区域B对应的辐射层112的温度较高，辐射更多红外线，以获得预期的收容结构11的第一区域A的温度高于第二区域B的温度的设计效果，即，获得预期的加热组件10的高温区域位于第一区域A的设计效果；有效提高了气溶胶生成制品2对应第一区域A的部分雾化效率，加快了气溶胶的生成速度。
在具体实施例中，结合图9，至少一个加热膜12中的每一加热线121的材料及厚度相同；若想要按照预期设计不同的温度区域，可以通过控制不同区域的多个加热部的宽度及各个区域所含的至少一个加热膜12沿收容结构11的长度方向C的长度，以控制不同区域的电阻密度大小，进而实现不同温度的区域的设计效果。比如，至少一个加热膜12中每一加热线121的宽度相同，可使沿收容结构11的长度方向C，至少一个加热膜12位于第一区域A的部分的长度小于位于第二区域B的部分的长度横截面积不同，以使至少一个加热膜12在第一区域A内的单位面积的电阻密度大于至少一个加热膜12在第二区域B内的单位面积的电阻密度。其中，加热线121的宽度指加热线121沿宽度方向D的尺寸。
在另一具体实施例中，参见图11至图13，图11为本申请另一实施例提供的加热组件的立体图；图12为图11的拆解示意图；图13为图11所示加热膜和供电组件沿收容结构的周向方向展开的示意图；与图4-图10所对应实施例不同的是：每一加热线121的两端分别与第一电极131和第二电极132电连接。
在该具体实施例中，如图13所示，每一加热线121包括依次连接的第一部分125、第二部分126以及第三部分127。第一部分125和第三部分127分别沿收容结构11的长度方向C延伸，且分别与第一电极131和第二电极132电连接；第二部分126沿收容结构11的周向方 向延伸。其中，第一部分125与第二部分126的连接处形成拐角，该拐角可为倒角；第二部分126与第三部分127的连接处也形成拐角，该拐角也可为倒角。
具体的，每一加热线121的第一部分125从第二区域B延伸至第一区域A，每一加热线121的第二部分126位于收容结构11的第一区域A；每一加热线121的第三部分127自第一区域A延伸至第二区域B以与第二电极132接触电连接。
具体的，结合图12和图13，加热膜12可包括并联的第一加热线121a和第二加热线121b。其中，第一加热线121a的第一部分125可呈曲线；比如为U型曲线。第一加热线121a的第二部分126和第三部分127呈直线。第二加热线121b的第一部分125、第二部分126以及第三部分127均呈直线。具体的，第二加热线121b的长度大于第一加热线121a的长度，且第二加热线121b包围第一加热线121a的外围。
在该具体实施例中，每一加热线121的两端可直接连接至第一电极131或第二电极132，即无需第二电连接部123或/或第三电连接部124。
当然，在其它实施例中，还可以通过控制对应区域的每一加热线121的材料或厚度来控制对应区域的电阻密度，本申请对此并不加以限制，只要保证至少一个加热膜12位于第一区域A的部分的电阻密度与至少一个加热膜12位于第二区域B的部分的电阻密度不同即可。
本领域技术人员可以理解，上述收容结构11也可以与其长度方向C垂直的其它一个平面或多个平行的平面作为分割线，以将收容结构11划分为多个区域。多个区域中至少两个区域所在的加热膜12的部分沿收容结构11的长度方向C的宽度不同，以对应形成不同温度的区域；其中，多个不同温度的区域中的高温区与收容结构11的长度方向C的中点偏置。
本实施例提供的加热组件10，通过红外线辐射加热气溶胶生成制品2，相比于电阻加热或电磁加热的方案，由于红外线具有一定的穿透性，不需要介质，加热效率较高，能够有效提高气溶胶生成制品2的预热效率，且能够有效降低气溶胶生成制品2内外的温度差，从而对气溶胶生成制品2的烘烤更加均匀，避免出现局部高温导致气溶胶生成制品2被烧焦的问题。同时，通过使至少一个加热膜12被配置为，在收容结构11的收容腔110内产生的高温区域与收容腔110的长度方向C的中点偏置，能够按照预期设计温度场，便于设计其它非对称的高温区域位置。另外，通过控制至少一个加热膜12的多条加热线121在不同区域的长度，以控制至少一个加热膜12在不同区域的电阻密度，从而控制各个不同区域所含加热膜12的功率密度；这样在至少一个加热膜12通电后，能够使至少两个加热区域的加热功率存在差异，由此形成温度不同的多个区域；以有目的性地设计适合气溶胶生成制品2雾化的收容结构11的高温区的位置，提高气溶胶的生成速度。此外，通过使至少一个加热膜12的位于第一区域A的部分的电阻密度大于位于第二区域B的部分的电阻密度，以使收容结构11的第一区域A的温度高于第二区域B的温度，进而有效提高了第一区域A的雾化效率，加快了气溶胶的生成速度。
在第二实施例中，参见图14，图14为本申请第二实施例提供的加热组件的横向截面图； 提供第二种加热组件10，与上述第一实施例提供的加热组件10不同的是：辐射层112设置于基体111的侧壁的外表面。
在该实施例中，如图14所示，在辐射层112为绝缘辐射层112时，加热膜12具体设置于辐射层112背离基体111的一侧表面。加热膜12通电后产生的热量直接热传导至辐射层112，辐射层112被加热产生红外线，红外线穿透透明的基体111进入至收容腔110，以加热收容于收容腔110内的气溶胶生成制品2。在该实施例中，气溶胶生成制品2也可直接于透明基体111接触，以将基体111的热量直接传导至气溶胶生成制品2进行加热；或者，气溶胶生成制品2与基体111间隔设置。
在辐射层112为非绝缘材质时，如图15所示，图15为本申请另一具体实施例提供的加热组件的横向截面图；为了避免加热膜12短路；辐射层112背离基体111的表面还设置有第二绝缘层114，第二绝缘层114位于辐射层112和加热膜12之间。
在第三实施例中，参加图16，图16为本申请第三实施例提供的加热组件的横向截面图；提供又一种加热组件10，与上述实施例提供的加热组件10不同的是：收容结构11包括基体111。
基体111呈中空管状，且基体111包括主体和分散于主体中的红外辐射材料。主体形成收容腔110和与收容腔110连通的近端开口，以收容气溶胶生成制品2。基体111被加热时辐射红外线以加热气溶胶生成制品2。可以理解，该实施例是基体111本身受热辐射红外线，基体111表面没有增设红外层。基体111具体可为石英管。
当然，为提高辐射红外线的量，以提高加热速度，也可在基体111的表面进一步设置辐射红外层；具体可参加上文，在此不再赘述。
以上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。
