现有技术中的加热不燃烧气溶胶产生装置，下壳体设置有进气口及与进气口和容纳管道连通的气道，在气溶胶生成基体加热且用户抽吸气溶胶时，外部空气从进气口进入气道再进入容纳管道，经过气溶胶生成基体内部将气溶胶输送到用户口中。本申请发明人发现，由于该结构的容纳管道与上盖距离近，加热元件的热量容易传到上盖使得温度较高，而上盖一般为用户手持部位，较高的上盖温度容易烫手，使得用户体验变差。另一方面，气道设置在下壳体，结构复杂、路径长，容易出现堵塞现象，降低气溶胶生成基体雾化效率。为了克服上述问题，本申请提供了一种新型的气溶胶产生装置。
请参阅图1至图3，图1是本申请提供的气溶胶产生装置的一实施例的整体结构示意图，图2是本申请提供的气溶胶产生装置的一实施例的爆炸结构示意图，图3是本申请提供的气溶胶产生装置的一实施例的剖视图。
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和电源组件5，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将收容腔10内的气溶胶生成基体4雾化以形成可供用户吸食的气溶胶。气溶胶生成基体4可以是植物草叶类气溶胶基质等固态基质。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。
如图3所示，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用于将接收器1外部的气体导入至发热组件2。
具体的，第一气道11形成于气溶胶生成基体4与收容腔10的内壁之间，用于将外部的气体导流至发热组件2。在用户使用该气溶胶产生装置100时，气流从第一气道11向发热组件2的一侧流动，可以直接到达发热组件2靠近收容腔10的端面，在接收器1和发热组件2之间的空腔处回流，然后气流再从发热组件2的端面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(图未示)以供用户抽吸。
在一实施例中，收容腔10为圆柱腔，收容腔10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能够穿过收容腔10到达发热组件2。在其他实施例中，收容腔10也可以为棱柱腔、矩形腔等，本申请对此不做限制。
请参阅图4至图6，图4是本申请提供的发热组件的爆炸结构示意图，图5是本申请提供的发热组件的一立体结构示意图，图6是图5提供的发热组件的俯视图。
在一实施例中，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设置于收容腔10的一端，发热件22插设于收容腔10内。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导向发热件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可被气溶胶生成基体4覆盖。
具体的，如图3和图5所示，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，进而进入第二气道23，并直接从第二气道23进入气溶胶生成基体4内，以对气溶胶生成基体4进行加热，提高雾化效率。
如图6所示，汇聚槽232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的周围进行流动。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，气溶胶生成基体4的横截面大于汇聚槽232的尺寸，使得汇聚槽232可被气溶胶生成基体4 覆盖，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等距离呈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、不规则或者逐渐向汇聚槽232的方向收窄。进气槽231侧壁的形状也不限定。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5所示，发热件22包括发热柱221和尖头部222，不同于现有技术中的扁平的发热件22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能够更容易进入或者取出气溶胶生成基体4，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。
如图4和图5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，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进入的气流在该端面处进行汇集，然后再进入进气槽231和气溶胶生成基体4，从而使得第一气道11进入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中。
请参阅图7至图9，图7是本申请提供的接收器和发热组件的结构示意图，图8是本申请提供的接收器的一实施例的爆炸结构示意图，图9是图7提供的接收器和发热组件的局部结构放大图。
在一实施例中，接收器1还包括端盖组件13，端盖组件13包括端盖131、 提取器132和安装件133，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1311，接受口1311用于周向定位气溶胶生成基体4，接受口1311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1311插入，并容置于收容腔10内。接受口1311与气溶胶生成基体4之间形成有进气缝隙(图未示)；或端盖131还设有连通降温段112的进气孔(图未示)。
具体的，接受口1311上设有凸起13111和与凸起13111连接的弧形面13112，凸起13111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13112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13112与气溶胶生成基体4之间的间隙可以作为进气缝隙1310以供外部气体进入。
如图8所示，提取器132包括收容腔10、安装腔1321和提取器安装座1322，安装腔1321设置在收容腔10一侧，且收容腔10和安装腔1321均形成于提取器安装座1322上，收容腔10和安装腔1321均为上下贯通的通孔，可以方便气体的进出。提取器安装座1322的边缘具有周向设置的凸缘13221，该凸缘13221将收容腔10和安装腔1321围绕于其中，同时该凸缘13221可以便于提取器132与安装件133的连接，如进行卡接、粘接等。安装件133套设于提取器132外部，且安装件133具有与提取器132相适应的外形以及能够套接于收容腔10外部的第一通孔1331，该第一通孔1331与接受口1311和收容腔10的端口均对应套接，使得气溶胶生成基体4能够从该第一通孔1331中穿过。
如图7所示，提取器132的收容腔10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之间形成进气通道110，以便于外部气体可以从该进气通道110中流过，到达发热组件2，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。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之间的进气通道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，最大可以设置为与接受口1311的凸起13111相接触的位置，优选为占提取器132内壁的一半或者不超过内壁的三分之二。凸筋130的具体数量和形状不限，只要能够满足彼此之间具有进气通道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。
在一实施例中，如图9所示，底座21朝向收容腔10的端面与接收器1之间形成有环形腔14，环形腔14环绕气溶胶生成基体4设置。该环形腔14具体形成于提取器132朝向底座21的端面上，与第一气道11靠近底座21的一端连通，同时该环形腔14环设于气溶胶生成基体4靠近底座21的一端，且气溶胶生成基体4位于环形腔14的中心位置，第二气道23的进气槽231也与该环形腔14连通，使得气体在该环形腔14处回流后，再从气溶胶生成基体4的底部进入，以便于气体从多个凸筋130的间隙形成的第一气道11内流过，并均匀地流入第二气道23内。环形腔14的外径与底座21靠近提取器132的端面大致相同。环形腔14朝向底座21的一端直径大于提取器132的一端，使得环形腔14朝底座21为发散状，更有利于气体的进入。可以理解，该环形腔14也可以是从提取器132朝向底座21的端面形成的一个凹槽，凹槽的底面具有通孔，该通孔即为接收器1的收容腔10。
请参阅图10至图11，图10是本申请提供的第一气道的结构示意图，图11是本申请提供的保温段和叶片段的一实施例的连接结构示意图。
在一实施例中，收容腔10内包括连通的保温段111和降温段112，保温段111相对临近发热组件2设置，降温段112相对临近收容腔10的端口设置；其中，在沿收容腔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。
具体的，保温段111和降温段112可以构成第一气道11设置在收容腔10内，且保温段111和降温段112为连续的两个气道段，保温段111临近发热组件2设置，具体为临近底座21靠近收容腔10的端面设置，使得底座21可以封盖于保温段111的一端。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。底座21可以用于支撑叶片段41的一端，使得叶片段41与底座21抵接以固定气溶胶生成基体4。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。发热件22插设于收容腔10内，并可以进一步插入叶片段41以实现对叶片段41加热，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。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。
如图10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11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，具体可以覆盖三分之一或者覆盖二分之一等，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，使得传输到气溶胶生成基体4的提取段42的热量更低，从而使得气溶胶生成基体4的提取段42的温度下降、冷却更快，对于用户来说，气溶胶的入嘴温度更低，可以提高用户的抽吸体验。
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相对临近收容腔10的端口设置，且发热件22并不插入至提取段42，使得提取段42的温度不会升高。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10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可以设置于外壳3的外部，这样更便于用户吸食。 同时，由于吸嘴段43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。
如图1、图2和图8所示，在一实施例中，外壳3包括相互配合连接的第一壳体31和第二壳体32，且设置于电源组件5外部，第一壳体31设置于相对于第二壳体32靠近端盖组件13的一侧，端盖组件13的端盖131具有第一连接端1312和第二连接端1313，第一连接端1312的高度小于第二连接端1313的高度，且第一连接端1312和第二连接端1313为平滑的弧度连接面，使得第一连接端1312相对于第二连接端1313位于远离外壳3的一侧。第一壳体31与端盖131的第一连接端1312以及第一连接端1312和第二连接端1313的弧度连接面连接，第二壳体32与第二连接端1313连接，以使得第一壳体31、第二壳体32与端盖组件13共同构成气溶胶产生装置100的椭圆柱体的外部形状。在其他实施例中，端盖组件13和外壳3的具体形状可以根据需要进行设置，本申请对此不做限制。
在一实施例中，如图2所示，第二壳体32上还开设有开孔321，开孔321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，用于安装并支撑发热组件2、电池51和线路板54等部件。支架52具有与发热保护壳214外形相适应的支撑腔521，该支撑腔521套设于发热保护壳214外部，且与支架52进行卡接，以对发热组件2形成支撑。在支撑腔521的外部还设有保温隔热件134，该保温隔热件134可以保持发热组件2的热量，减少热量损耗。同时该保温隔热件134与提取器132抵接，可以对提取器132与发热组件2进行密封。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吸食。
如图2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。
本申请公开的气溶胶产生装置，包括接收器和发热组件，接收器设有收容腔，收容腔用于收容气溶胶生成基体，发热组件的一端用以插设于气溶胶生成 基体内并加热气溶胶生成基体，发热组件朝向收容腔的端面设有第二气道；其中，第一气道与第二气道连通，以供接收器外部的气体经第一气道与第二气道进入至气溶胶生成基体内。通过设置第一气道使得接收器和气溶胶生成基体间隔设置，使得气流能够对接收器进行降温。另外，通过在发热组件朝向收容腔的端面直接设置第二气道，可以简化接收器结构。且外部空气直接从第一气道与第二气道进入气溶胶生成基体内，气道路径短，不易发生堵塞现象，从而提升用户的抽吸体验。
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。
