本申请提供的气溶胶产生装置100包括接收器1、发热组件2、外壳3、电源组件5和开关6，接收器1设有收容腔10，发热组件2的一端插设于收容腔10内，用以插设于气溶胶生成基体4内并加热气溶胶生成基体4。收容腔10用于收容气溶胶生成基体4，收容腔10的形状和大小不限，可以根据需要设计。电源组件5与发热组件2连接，用于向发热组件2供电。在电源组件5的驱动下，发热组件2加热收容腔10内的气溶胶生成基体4以雾化形成可供用户吸食的气溶胶。气溶胶生成基体4可以是植物草叶类等固态基体。气溶胶产生装置100具体可用于不同的领域，比如医疗、美容、休闲吸食等。电源组件5包括电池51、支架52、驱动件(图未示)以及控制器(图未示)等。电池51用于为发热组件2供电，以使得发热组件2能够加热气溶胶生成基体4以形成气溶胶。开关6用于启动或关闭气溶胶产生装置100。
请参阅图4至图7，图4是本申请提供的第一气道和气溶胶生成基体的连接结构示意图，图5是本申请提供的保温段和叶片段第一实施例的连接结构示意图，图6是本申请提供的保温段和叶片段第二实施例的连接结构示意图，图7是本申请提供的保温段和叶片段第三实施例的连接结构示意图。
在一实施例中，收容腔10的内壁设有第一气道11。第一气道11包括相互连通的保温段111和降温段112，保温段111相对降温段112临近收容腔10底部设置，在收容腔10的轴向方向上，也就是气溶胶生成基体4插入收容腔10的方向上，保温段111的横截面积大于降温段112的横截面积，第一气道11用于供接收器1外部的气体经降温段112和保温段111流入至发热组件2。
如图3和图4所示，发热组件2包括底座21和设置于底座21上的发热件22，底座21可以封盖于保温段111的一端，还用于支撑叶片段41，发热件22插设于收容腔10内。发热组件2的一端用于插入叶片段41，具体为发热件22插入叶片段41以实现对叶片段41加热，发热件22可以插入叶片段41的一部分，也可以插入叶片段41的全部长度，提高加热效果，本申请对此不做限定。
具体的，气溶胶生成基体4在使用时插入收容腔10内，气溶胶生成基体4可以包括插设于收容腔10内的叶片段41和提取段42，保温段111可以覆盖至少部分的叶片段41，降温段112用于覆盖至少部分的提取段42。气溶胶生成基体4底部靠近底座21，保温段111设置于靠近底座21的一侧，因此保温段111可以对气溶胶生成基体4靠近底座21的一侧进行保温，即对气溶胶生成基体4的叶片段41进行保温。也就是说，保温段111的内腔与叶片段41是至少部分重合的，保温段111可以完全覆盖叶片段41，也可以只覆盖一部分叶片段41。
如图5所示，当保温段111完全覆盖叶片段41时，即保温段111的长度与叶片段41的长度之比大于等于1.0，保温段111的横截面积大于降温段112的横截面积，此时保温段111内的空气对流换热系数相对较小，可以提高对叶片段41的保温效果，防止来自发热件22的热量散发过快，提高对气溶胶生成基体4的加热效率和雾化效果，提升用户的抽吸体验。同时，可以降低气溶胶产生装置100的热量损耗。
如图6和图7所示，当保温段111只覆盖一部分叶片段41时，例如，保温段111覆盖叶片段41的长度部分与叶片段41的长度之比大于等于0.25，具体可以覆盖如图7所示的三分之一或者覆盖如图6所示的二分之一等，本申请对此不做限定。但是为了保证保温段111对叶片段41的保温效果，保温段111覆盖叶片段41的长度部分与叶片段41的长度之比至少应该大于等于0.25。此时，保温段111对叶片段41的保温效果相对于保温段111完全覆盖叶片段41有所降低，但是降温段112对气溶胶生成基体4的提取段42的降温效果会更明显，对于用户来说，气溶胶的入嘴温度更低。
在一实施例中，保温段111的长度与叶片段41的长度之比大于等于0.25。需要注意的是，此处为保温段111的长度与叶片段41的长度之间的比值，而不是保温段111覆盖叶片段41的长度与叶片段41的长度之间的比值。如上，由于保温段111可以不完全覆盖叶片段41，因此保温段111的长度与保温段111覆盖叶片段41的长度并不能简单等同，只有当保温段111的长度与叶片段41的长度相等时，保温段111的长度与保温段111覆盖叶片段41的长度才是相等的。
具体的，如图4至图7所示，由于保温段111需要至少部分覆盖叶片段41，那么保温段111就需要满足一定的长度，以保证对叶片段41的保温效果。叶片段41设置于保温段111内，保温段111需要对叶片段41进行保温时，保温段 111的长度至少应该是叶片段41的长度的四分之一，也可以为三分之一、二分之一或者大于等于叶片段41的长度等，本申请对此不做限定。可以理解，保温段111的长度越长，对叶片段41的保温效果越好。在本实施例中，当底座21封盖于保温段111的一端时，气溶胶生成基体4插入收容腔10，气溶胶生成基体4与保温段111靠近的一端与底座21抵接，使得底座21能够对叶片段41形成支撑，即叶片段41远离提取段42的一端与底座21的端面相抵接。优选地，保温段111的长度最长可以为略长于叶片段41的长度，例如，保温段111的长度与叶片段41的长度之比为1.25。如果保温段111的长度过长时，会使得保温段111对气溶胶生成基体4的提取段42进行保温，从而降低降温段112对提取段42的降温效果。
降温段112用于覆盖至少部分气溶胶生成基体4的提取段42，如上所述，降温段112设置于收容腔10远离发热组件2的一侧，且发热件22并不插入至提取段42，不会导致提取段42的温度过高的问题。降温段112的横截面积小于保温段111的横截面积，此时空气在此处的流动速度较快，具有较高的对流换热系数，从而对提取段42起到冷却作用，进而降低气溶胶的入嘴温度。
如图4所示，在其他实施例中，气溶胶生成基体4还可以包括吸嘴段43，吸嘴段43为提取段42远离叶片段41的一端，可以理解，吸嘴段43是供用户吸食的部分，因此，吸嘴段43可以设置于壳体3的外部，这样更便于用户吸食。同时，由于流至吸嘴段43的气溶胶经过了提取段42的降温，使得进入用户口中的气溶胶温度大大降低，提高了气溶胶的入嘴口感，并进一步提升用户体验。
在一实施例中，降温段112为圆柱腔，降温段112的径向尺寸大于气溶胶生成基体4的径向尺寸，使得气溶胶生成基体4能够穿过降温段112到达保温段111。在其他实施例中，降温段112也可以为棱柱腔、矩形腔等，本申请对此不做限制。
请参阅图8至图10，图8是本申请提供的发热组件的爆炸结构示意图，图9是本申请提供的发热组件的一立体结构示意图，图10是图9提供的发热组件的俯视图。
在一实施例中，底座21朝向收容腔10的端面还设有第二气道23，第二气道23与第一气道11连通，且第二气道23朝向发热件22。第二气道23包括至少一条进气槽231以及汇聚槽232，进气槽231从底座21的边缘向发热件22延伸。汇聚槽232环绕发热件22设置，进气槽231连通汇聚槽232，且汇聚槽232 能够被气溶胶生成基体4覆盖。
具体的，第二气道23与第一气道11连通，使得外部气体能够从第一气道11进入底座21，再从第二气道23进入气溶胶生成基体4内，以将加热形成的气溶胶运送至吸嘴段以供用户抽吸。
如图3和图10所示，汇聚槽232优选为设置在底座21的中心位置，环绕发热件22设置，进气槽231从底座21的边缘向发热件22汇集，且与汇聚槽232连通。使得气体能够在汇聚槽232和发热件22的周围流动。同时，由于气溶胶生成基体4插入收容腔10之后，发热件22从气溶胶生成基体4的底端插入至叶片段41，气溶胶生成基体4的横截面大于汇聚槽232的尺寸，使得气溶胶生成基体4能够覆盖汇聚槽232，从而使得气体也能够进入气溶胶生成基体4内。
优选地，进气槽231的数量为多条，多条进气槽231呈放射状设置于汇聚槽232的周侧。具体的，多条进气槽231以等距离放射状的排列方式均布于汇聚槽232的周围，使得第二气道23能够均匀进气。进气槽231侧壁可以是等宽、不规则或者等距离逐渐向汇聚槽232的方向收窄，如，进气槽231侧壁截面为平行的，或者为波浪形的，或者为发射状等，进气槽231侧壁的形状具体不做限定。在本实施例中，进气槽231从底座21的边缘至汇聚槽232逐渐收窄，形成一个喇叭形状的进气槽231，使得气流从四周向中心能够更好地汇聚。
如图8和图9，发热件22包括发热柱221、尖头部222和引线部223，不同于相关技术中发热件22的扁平的结构，本申请的发热件22的主体为柱状，在柱状远离底座21的一端为发热件22的尖头部222。通过将发热件22设计为发热柱221和尖头部222，使得发热件22能够更容易进入气溶胶生成基体4，或者从气溶胶生成基体4取出，不容易发生叶片粘连的情况。同时，柱状的发热件22使得气溶胶生成基体4能够以旋转的方式脱离发热件22，更便于气溶胶生成基体4的提取。引线部223设置于发热柱221远离尖头部222的一端，可以与电源组件5连接，使得电源组件5为发热件22供电以加热气溶胶生成基体4。
如图8和图9所示，在底座21远离发热件22的一侧设置有发热保护壳214，该发热保护壳214为具有空腔的柱状体，发热件22远离提取器132的一端伸入发热保护壳214的柱状体内，使得发热保护壳214部分包围发热件22，并能够对发热件22进行保护。发热保护壳214与底座21可以通过卡接、螺钉连接或者螺纹连接等方式进行连接，具体连接方式本申请不做限定。
在一实施例中，底座21的外侧壁具有第一台阶211和第二台阶212，第一 台阶211形成于底座21的外侧壁上靠近进气槽231的一侧，且第一台阶211与多个进气槽231连通，用于汇集来自接收器1的气流。第二台阶212形成于底座21的外侧壁远离进气槽231的一侧。第一台阶211与第二台阶212之间还设有密封件213。
具体的，第一台阶211和第二台阶212均为环形，第一台阶211的上端面与多个进气槽231连通，使得从接收器1进入的气流在第一台阶211的上端面处进行汇集，然后再进入进气槽231和气溶胶生成基体4，从而使得从外部进入第一气道11的气流能够均匀地流入第二气道23。第一台阶211与第二台阶212之间设置密封件213，使得气流不会进入电源组件5中对电源组件5造成损坏。
请参阅图11至图13，图11是本申请提供的接收器的剖视图，图12是本申请提供的提取器的一立体结构示意图，图13是图12提供的提取器的俯视图。
在一实施例中，接收器1包括可拆卸连接的容纳组件12和端盖组件13，容纳组件12和端盖组件13内共同形成收容腔10。端盖组件13设有降温段112，且端盖组件13可拆卸连接于容纳组件12的一端，并与容纳组件12相配合界定出保温段111。
具体的，端盖组件13包括端盖131、提取器132和磁性件134，端盖131盖设于提取器132上，且端盖131对应于提取器132的端口设有接受口133，接受口133用于周向定位气溶胶生成基体4，接受口133与提取器132远离底座21的端口对应设置。气溶胶生成基体4从接受口133插入，并容置于收容腔10内。接受口133与气溶胶生成基体4之间形成有进气缝隙1330，用于外部气体进入第一气道11，或者端盖131还设有连通降温段112的进气孔1331，该进气缝隙1330与进气孔1331可以设置其中一个或者两个都设置。进气孔1331可以为开设在端盖131上面或者侧面的一个通孔，也可以是端盖131与气溶胶生成基体4之间预留的进气口，以使得气体可以从该通孔或者进气口中进入第一气道11。磁性件134设置于端盖131和提取器132之间，磁性件134用以与容纳组件12磁吸连接。
具体的，接受口133上设有凸起1332和与凸起1332连接的弧形面1333，凸起1332与气溶胶生成基体4相抵接，可以固定气溶胶生成基体4；弧形面1333与气溶胶生成基体4之间具有一定的间隙，使得外部气体可以进入收容腔10。弧形面1333与气溶胶生成基体4之间的间隙可以作为进气缝隙1330以供外部气体进入。
提取器132可拆卸连接于端盖131内，提取器132设有降温段112，且提取器132和端盖131的内壁之间形成有插接腔136，容纳组件12背离底座21的一端插入插接腔136。
具体的，提取器132与气溶胶生成基体4之间具有一定的空隙，可以形成该降温段112。提取器132外表面具有一个周向设置的凸环1321，当提取器132设置于端盖131内时，该凸环1321与端盖131之间形成一个空腔，即为插接腔136。容纳组件12远离底座21的一端插入该插接腔136中，以对容纳组件12进行固定。
在一实施例中，容纳组件12可以包括磁性容纳管122和定位管121，磁性容纳管122的一端插设于插接腔136内，与提取器132的凸环1321抵接。定位管121套设于磁性容纳管122内，定位管121内具有收容腔10，定位管121的内壁与提取器132的外壁定位配合，提取器132插入收容腔10内并界定出保温段111。
具体的，定位管121的内壁与提取器132靠近底座21的外侧壁相抵接，且在提取器132靠近底座21的端部、定位管121的内壁以及底座21的端面之间定位出一个空腔，该空腔为第一气道11的保温段111。当气溶胶生成基体4插入接收器1内的收容腔10时，其底部与底座21的端面接触，气溶胶生成基体4的叶片段41可以至少部分位于保温段111中，使得保温段111能够对叶片段41进行保温。
在其他实施例中，容纳组件12也可以为一体式的单管结构，即磁性容纳管122和定位管121为一个整体嵌设于插接腔136内，与提取器132的凸环1321抵接，同样也可以实现容纳组件12的功能，本申请对此不做限制。
磁性件134具体设置于端盖131和提取器132的凸环1321之间，在本实施例中，提取器132、磁性容纳管122和端盖131可以为金属件，磁性容纳管122和磁性件134分别设置于凸环1321的两侧，且端盖131套设于磁性容纳管122和磁性件134的外部，通过磁性件134的磁吸作用，使得磁性容纳管122、提取器132和端盖131可以形成一个一体组合结构，以便于气溶胶产生装置100整体结构的安装。同时，构成该一体组合结构的磁性容纳管122、提取器132和端盖131彼此之间相互磁吸，具有一定的重量，使得气溶胶生成基体4更容易从提取器132中取出。可以理解，提取器132、磁性容纳管122和端盖131也可以为其他材质，即使不形成一体组合结构，也可以实现本申请的功能。磁性件134 可以为磁铁或者设有磁性涂层的其他材料构成的结构，具体根据需要进行选择，本申请对此不做限制。
如图12和图13，提取器132的内壁设有至少一条凸筋130，凸筋130用以定位气溶胶生成基体4，并用于引导接收器1外部的气体至发热组件2。
具体的，凸筋130设置于提取器132的内壁表面，使得气溶胶生成基体4和提取器132之间形成进气间隙110，以便于外部气体可以从该进气间隙110中流过，到达发热组件2。同时凸筋130可以对气溶胶生成基体4进行固定，使得气溶胶生成基体4和提取器132保持在同轴的位置，不容易发生偏移。凸筋130的数量可以一条或者多条，设置多条凸筋130时，凸筋130相互之间需要间隔设置，且多条凸筋130沿收容腔10的周向分布，以使得收容腔10中有足够的空间供气溶胶生成基体4插入。相邻的两条凸筋130之间的进气间隙110也作为第一气道11的一部分，用于将外部气体导入至发热组件2。在本实施例中，凸筋130分布于提取器132内靠近底座21的一部分内壁，在其他实施例中，凸筋130也可以设置于与接受口133的凸起1332相接触的位置，本申请并不对此进行限制。凸筋130与提取器132可以为一体结构或者在提取器132内单独设置的结构，具体不做限定。凸筋130的具体数量和形状不限，只要能够满足凸筋130彼此之间具有进气间隙110，且能够使得气溶胶生成基体4穿过即可，本申请对此不做限制。
进一步的，凸筋130设有导向面1301，该导向面1301朝向提取器132远离底座21的端口设置，可以用于引导气溶胶生成基体4方便地插入多条凸筋130所限定的定位空间内。导向面1301可以为斜面或者弧面，也可以为其他面，只要能够实现对气溶胶生成基体4的导向作用即可，本申请对此不做限制。
如图2和图3所示，外壳3设置于电源组件5外部，外壳3上还开设有开孔31，开孔31可以用于安装气溶胶产生装置100的开关6。支架52设置于外壳3内，用于安装并支撑电池51和线路板54等部件。电池51与发热件22连接，用于给发热件22供电，使得发热件22能够对气溶胶生成基体4加热以形成气溶胶供用户抽吸。
如图3和图8所示，端盖组件13与外壳3之间可以通过螺纹、卡接等方式进行连接，密封件213的设置可以防止气流进入电源组件5内，对电源组件5内的部件造成损坏或者腐蚀等。端盖组件13与外壳3之间也可以设置其他密封件或者连接件，以保证端盖组件13与外壳3的紧密连接。
