下面结合附图和实施例对本申请进行详细的说明。
请参阅图1，图1为本申请一实施例提供的加热组件的整体结构示意图；图2为本申请第一具体实施例提供的加热组件的剖视图；在本实施例中，提供一种加热组件10，该加热组件10用于在通电时加热并雾化气溶胶生成制品22(见下图11)，以形成气溶胶。该加热组件10可用于不同的领域，例如医疗、美容、休闲吸食等领域。其中，气溶胶生成制品22优选采用固体基质，可以包括烟草、香草叶、茶叶、薄荷叶等植物叶类，一种或多种的粉末、颗粒、碎片细条、条带或薄片中的一种或多种；或者，固体基质可以包含附加的挥发性香味化合物，以在基质受热时被释放。当然，气溶胶生成制品22也可为液体基质或膏状基质，比如添加香气成分的油类、药液等。以下实施例均以气溶胶生成制品22采用固体基质为例。
如图2所示，该加热组件10包括基体1、辐射层2和电极层3。
其中，参见图3，图3为本申请一实施例提供的基体的整体结构示意图；基体1为一端开口11的中空腔体12，比如，基体1可为中空圆柱体，用于通过开口11将气溶胶生成制品22收容于腔体12内或从腔体12内移出。其中，腔体12的内径尺寸可根据所需收容的气溶胶生成 制品22的外径进行适配，以减小气溶胶生成制品22与腔体12侧壁之间的间隙。
其中，通过使用于收容气溶胶生成制品22的基体1为一端开口11的中空腔体12，相比于两端开口的中空基体，能够在抽吸过程中，有效减少通过腔体12流经气溶胶生成制品22的低温新鲜空气流的量，从而使气溶胶生成制品22在加热初期能够处于负压少氧状态；而在少氧负压抽吸条件下，气溶胶生成制品22中的物料主要发生氢化、还原和裂解反应，有效增加了雾化形成的致香物质的种类和含量，克服了新鲜空气流流经气溶胶生成制品22时带来的因氧化充分使致香物质较少的问题。同时，能够保证气溶胶生成制品22一直处于较为稳定的裂解温度环境，克服了因新鲜空气流流经气溶胶生成制品22使得气溶胶生成制品22的温度急剧下降而导致的裂解反应不稳定的问题。
如图2所示，辐射层2对应于基体1的侧壁设置，用于在被加热时辐射红外线，以加热腔体12内的气溶胶生成制品22；有效提高了气溶胶生成制品22的利用率及加热的均匀性。当然，在其它实施例中，辐射层2可进一步对应于基体1的底壁(即，相对开口11设置的一端的端壁)设置，以提高加热组件10的加热效率。
在具体实施例中，辐射层2可为红外层，红外层在加热时辐射红外线，由于红外线的热辐射能力较强，使得红外线可以穿透气溶胶生成制品22的内部而对气溶胶生成制品22的内外整体同时进行加热，减小了气溶胶生成制品22的内外温差，相比于常规的电阻式加热方式或电磁式加热方式，红外加热方式的加热均匀性更好，可避免因局部高温导致气溶胶生成制品22被烧焦的问题。辐射层2具体可为远红外陶瓷层、金属层或导电碳层，具体可根据需要进行选择。
在一具体实施例中，辐射层2为红外陶瓷涂层，辐射层2在工作时辐射红外线，以加热气溶胶生成制品22。红外加热波长为2.5um～20um，针对加热气溶胶生成制品22的特点，通常加热温度在200℃～300℃时，红外发射率在0.8以上。而当加热温度达到350℃左右，能量辐射极值主要在3～5um波段。
在一实施例中，请继续参阅图2，辐射层2具体设置于基体1的侧壁的外壁面所在的一侧，辐射层2辐射的红外线穿过基体1进入腔体12内部，以对收容于腔体12内的气溶胶生成制品22进行加热。具体的，基体1可为透明基体；这样能够使辐射层2辐射的红外线更多地透过基体1以加热腔体12内的气溶胶生成制品22，有效提高了红外线的利用率和气溶胶生成制品22的加热效率。
在一具体实施例中，如图2所示，电极层3与辐射层2电连接，电极层3通电后，辐射层2有电流流过，辐射层2的温度升高，激发较高的红外线辐射；因透明的石英的基体1可透过小于4μm波长的红外辐射，所以辐射层2激发的红外线能量透过基体1加热腔体12内的气溶胶生成制品22；同时基体1被辐射层2加热，激发远红外辐射加热其内的气溶胶生成制品22，由此可对腔体12内的气溶胶生成制品22进行辐射加热与热传导加热，可提高气溶胶生成制品22的加热均匀性及利用率。
其中，如图2所示，电极层3可设置于辐射层2背离基体1的一侧表面，以与辐射层2电连接。当然，在辐射层2未覆盖基体1的两端边缘时，如图4所示，图4为本申请第二具体实施例提供的加热组件的剖视图；电极层3还可以设置于基体1的两端边缘，并位于基体1的侧壁的外壁面，且与辐射层2同层设置，从而实现与辐射层2电连接；如此，能够充分利用基体1表面的空间位置，以减小整个加热组件10的空间占地面积。
具体的，电极层3可采用高导热率金属材料烧结在辐射层2上或基体1的侧壁的外壁面。
在该实施例中，基体1的材质可以为绝缘基材。基体1具体可以选用耐高温且具有较高的红外线透过率的材料制成，包括但不限于以下材料：石英玻璃、钇铝石榴石单晶、锗单晶、氟化镁陶瓷、氧化钇陶瓷、镁铝尖晶石陶瓷、蓝宝石、碳化硅等等。优选的，基体1由石英玻璃制成。
辐射层2具体可采用丝印、涂敷、溅射、印刷或流延成型等方式形成于基体1的侧壁的整个外壁面上，以保证位于腔体12内的气溶胶生 成制品22均能够被加热。其中，该辐射层2可根据实际需要对其形状、面积及厚度进行设置；例如根据加热组件10的温度场的预设方案对该辐射层2的形状、面积及厚度进行设置。例如，辐射层2的形状可以为连续的膜状、多孔的网状或条状等，具体可制成膜状面发热。可以理解，为了使辐射层2的加热效果更均匀，其在基体1上各处的厚度通常是一致的；当然，对于一些特殊的需求，辐射层2在基体1上各处的厚度也可以设置成不同的，从而使得加热组件10的不同区域的红外线能量密度不同，即加热组件10通电工作时，不同区域的热量密度不同，以形成不同的温度场。
具体的，辐射层2可选用导电发热的导体或半导体材料。比如辐射层2的材质为具有金属特性的ABO3型钙钛矿材料。其中，A为La、Sr、Ca、Mg、Bi中的一种或多种，B为Al、Ni、Fe、Co、Mn、Mo、Cr中的一种或多种。
当然，在其它具体实施例中，基体1的材质还可以是导电金属基材，比如不锈钢基材或者金属铝基等等。为了防止基体1与辐射层2之间短路；加热组件10还包括绝缘层，绝缘层设置于辐射层2与电阻加热层5之间。绝缘层具体可采用丝印、涂敷、溅射、印刷或流延成型等方式形成于基体1的侧壁的外壁面。绝缘层的材质具体可为陶瓷、石英玻璃、云母等耐高温的绝缘材料。
在另一具体实施例中，参见图5，图5为本申请第三具体实施例提供的加热组件的剖视图；与上述图2所对应实施例提供的加热组件10不同的是：加热组件10还包括导电线圈4，电极层3具体与导电线圈4电连接，以向导电线圈4通电。辐射层2包括红外材料和掺杂于红外材料中的铁磁性材料。其中，红外材料可以为钙钛矿、尖晶石、橄榄石和碳化物中的一种或多种。铁磁性材料可以为铁基、钴基或镍基金属或合金、以及铁氧体中的一种或多种。
在该具体实施例中，导电线圈4围绕辐射层2的外围设置，用于在通电产生变化磁场。辐射层2的铁磁性材料在变化磁场中形成涡流而被加热。
具体的，导电线圈4可为导电金属材质，例如铜、铝、银等材质，在该实施例中，优选导电线圈4为铜材质的金属线圈。导电线圈4具体可为漆包线或利兹线，绕设于辐射层2的背离基体1的一侧；可以理解的是，在该实施例中，导线外的漆为绝缘材质，以防止线圈之间发生短路问题。
在又一具体实施例中，参见图6，图6为本申请第四具体实施例提供的加热组件的剖视图；与上述图2所对应实施例提供的加热组件10不同的是：加热组件10还包括：电阻加热层5，设置于辐射层2背离基体1的一侧表面。电极层3具体与电阻加热层5电连接，电极层3通电后，电流流过电阻加热层5，使电阻加热层5产生热量，以加热辐射层2，从而使辐射层2被加热而辐射红外线。具体的，电极层3可设置于电阻加热层5背离辐射层2的一侧表面或与电阻加热层5同层设置，本实施例对电极层3的设置方式不作限定，只要实现与电阻加热层5的电连接即可。
其中，电阻加热层5具体可以是面发热形式，比如为连续的圆柱面。当然，电阻加热层5也可以为任意满足加热效果的图形，比如参见图7，图7为本申请一实施例提供的辐射层、电阻加热膜层以及电极层的平面示意图；电阻加热层5还可以为W型、或M型或螺旋型等等。
电阻加热层5的材质可用金属Ag和玻璃的混合物，或银钯合金等具有电阻的正温度系数特性的材料；或其他类型具有电阻的负温度系数特性的电阻电热材料。
在该具体实施例中，辐射层2的材质可以为可导电或绝缘的高红外发射率材料；如：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制成。在辐射层2为可导电的材料时，辐射层2与电阻加热层5之间可进一步设置一绝缘层，以防止短路。绝缘层的材质及设置方式与上述所涉及的绝缘层类似。
在另一实施例中，参见图8，图8为本申请第五具体实施例提供的加热组件的剖视图；与上述图2至图7所对应实施例提供的加热组件10 不同的是：辐射层2设置于基体1的侧壁的内壁面所在的一侧；相比于辐射层2设置于基体1的侧壁的外壁面所在的一侧的方案，辐射层2辐射的红外线能够直接加热气溶胶生成制品22，无需穿过基体1，进一步提高了红外线的利用率。
其中，在一具体实施例中，如图8所示，电极层3同样可与辐射层2电连接，以在电极层3通电后，电流流过辐射层2，使辐射层2的温度升高，激发较高的红外线辐射；具体可参见上述图2所对应实施例的相关描述。其中，如图8所示，该具体实施例中的电极层3，也可设置于基体1的侧壁的内壁面，并与辐射层2同层设置。当然，电极层3也可设置于基体1背离辐射层2的一侧表面，或者设置于辐射层2背离基体1的一侧表面。
其中，基体1可为绝缘基材，辐射层2具体设置于基体1的侧壁的内壁面上，具体可参见上述相关文字。当然，基体1也可为导电金属基材，此时，为了防止辐射层2与基体1之间短路，可在辐射层2与基体1之间设置绝缘层。
在另一具体实施例中，参见图9，图9为本申请第六具体实施例提供的加热组件的剖视图；与上述图8所对应实施例提供的加热组件10不同的是：基体1还包括导电线圈4，电极层3具体与导电线圈4电连接，以向导电线圈4通电。在该具体实施例中，基体1由能够感应变化磁场产生涡流而发热的材料制成；基体1具体可为金属基材，比如铁基、钴基或镍基金属或合金、以及铁氧体中的一种或多种。
在该具体实施例中，导电线圈4围绕基体1的外围设置，用于在通电产生变化磁场。基体1在导电线圈4产生的高频变化磁场中感应磁场变化而产生涡流并发热，从而将电能转化为热能，然后通过热传导将热量传递给辐射层2，使得辐射层2升温而被激发，进而辐射加热红外线，以加热气溶胶生成制品22。
具体的，辐射层2也可由能够感应变化磁场产生涡流而发热的材料制成，以使辐射层2在导电线圈4产生的高频变化磁场中也能感应磁场变化而产生涡流并而加热；从而提高加热组件10的整体加热效率。需 要说明的是，在该实施例中，辐射层2与基体1之间设置有绝缘层。
在又一具体实施例中，参见图10，图10为本申请第七具体实施例提供的加热组件的剖视图；与上述图8所对应实施例提供的加热组件10不同的是：加热组件10还包括：电阻加热层5，设置于基体1背离辐射层2的一侧。电极层3具体与电阻加热层5电连接，电极层3通电后，电流流过电阻加热层5，使电阻加热层5产生热量，以加热基体1，基体1通过热传导将热量传导至辐射层2，从而使辐射层2被加热而辐射红外线。其中，电极层3可设置于电阻加热层5背离辐射层2的一侧表面或者与电阻加热层5同层设置。具体可参见上述电极层3的设置方式。
其中，在基体1为绝缘基材时，电阻加热层5可设置于基体1背离辐射层2的一侧表面。在基体1为导电金属基材时，电阻加热层5和基体1之间设置有绝缘层，以防止短路。绝缘层的材质及具体设置方式可参见上述相关描述。
本实施例提供的加热组件10，通过使用于收容气溶胶生成制品22的基体1为一端开口11的中空腔体12，能够在抽吸过程中，有效减少通过腔体12流经气溶胶生成制品22的低温新鲜空气流的量，从而使气溶胶生成制品22在加热初期能够处于负压少氧状态；而在少氧负压抽吸条件下，气溶胶生成制品22中的物料主要发生氢化、还原和裂解反应，有效增加了雾化形成的致香物质的种类和含量，克服了新鲜空气流流经气溶胶生成制品22时带来的因氧化充分使致香物质较少的问题。同时，能够保证气溶胶生成制品22一直处于较为稳定的裂解温度环境，克服了因新鲜空气流流经气溶胶生成制品22使得气溶胶生成制品22的温度急剧下降而导致的裂解反应不稳定的问题。另外，通过在基体1的侧壁上设置辐射层2，以在被加热时辐射红外线，从而加热腔体12内的气溶胶生成制品22，有效提高了气溶胶生成制品22的利用率及加热的均匀性。
参见图11，图11为本申请一实施例提供的雾化器的结构示意图。在本实施例中，提供一种雾化器20，该雾化器20包括加热组件10、壳体21以及气溶胶生成制品22。其中，加热组件10为上述任一实施例所 提供的加热组件10，其具体结构与功能可参见上述相关描述，在此不再赘述。
壳体21的部分可拆卸式连接于加热组件10的腔体12内，其余部分延伸出加热组件10。在具体实施例中，壳体21具有收容腔、出气通道212和至少一进气孔211。其中，收容腔形成于壳体21的位于加热组件10内的部分，气溶胶生成制品22收容于收容腔内。出气通道212连通收容腔和每一进气孔211。进气孔211的数量可为两个、三个、四个或更多个。每一进气孔211分别连通收容腔与外界空气，且每一进气孔211开设于壳体21的伸出加热组件10外的部分上，并靠近加热组件10的开口11。在抽吸过程中，空气流从进气孔211流入，经过基体1的开口11将加热组件10雾化形成的气溶胶带走，并从出气通道212流出。
本实施例提供的雾化器20，通过使基体1为一端开口11的中空腔体12，将与收容腔连通的进气孔211设置于基体1外，并位于壳体21靠近基体1的开口11的位置，能够在抽吸过程中，将加热组件10雾化形成的气溶胶带走，并有效减少通过流经气溶胶生成制品22的低温新鲜空气流的量，从而使气溶胶生成制品22在加热初期能够处于负压少氧状态；而在少氧负压抽吸条件下，气溶胶生成制品22中的物料主要发生氢化、还原和裂解反应，有效增加了雾化形成的致香物质的种类和含量，克服了新鲜空气流流经气溶胶生成制品22时带来的因氧化充分使致香物质较少的问题。同时，能够保证气溶胶生成制品22一直处于较为稳定的裂解温度环境，克服了因新鲜空气流流经气溶胶生成制品22使得气溶胶生成制品22的温度急剧下降而导致的裂解反应不稳定的问题。
