除非另有定义，本说明书所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本说明书中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是用于限制本申请。本说明书所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1-图5所示，本申请一实施方式提供的一种气溶胶生成装置100，气溶胶生成装置100整体呈圆柱状，包括上壳体10、提取器20、保持件30、隔热件40、密封件50以及电源组件60。
上壳体10设置在提取器20和保持件30外，上壳体10与提取器20上端的端部抵接。上壳体10与电源组件60的下壳体61构成气溶胶生成装置100 的外壳，上壳体10与下壳体61齐平，保持外观整洁一致。上壳体10的上端(或者气溶胶生成装置100的口端)具有插入口，气溶胶生成制品200通过该插入口可移除地接收在腔室A中。
提取器20用于提取接收于腔室A的气溶胶生成制品200。提取器20被构造成沿腔室A的轴向延伸的管状，管状的中空部分形成至少部分腔室A。在提取器20未提取气溶胶生成制品200时，其下端伸入到保持件30内，上端保持在保持件30上端的端部上。
如图6所示，保持件30包括一体形成的底端盖30a、管状体30b、固定臂30c以及延长臂30d。具体地，
底端盖30a大致沿气溶胶生成装置100的横向方向延伸。具体地，底端盖30a包括呈柱状的座体、自该座体朝向气溶胶生成装置100外径向延伸的部分；座体朝向气溶胶生成装置100的底壁方向延伸。座体具有通孔或者固定孔，通孔的形状与加热器31的远端的形状相匹配。加热器31的近端被构造成可插入接收于腔室A的气溶胶生成制品200中，加热器31的远端保持在该通孔中，可通过焊接、打胶等方式固定。
由于座体与加热器31的远端之间直接接触，座体具有较大的热量，温度介于100℃～300℃，因此需要避免座体与上壳体10的内侧壁之间直接径向接触，以下详细进行说明。可以想象得到的，自该座体朝向气溶胶生成装置100外径向延伸的部分，虽然与加热器31的远端之间没有直接接触，但与座体直接连接，因此该部分的热量同样较大，也需要避免与上壳体10的内侧壁直接径向接触。进一步地，对于管状体30b，其围绕腔室A布置，因此管状体30b的热量也较大(温度略低于底端盖30a)，也需要考虑避免与上壳体10的内侧壁直接径向接触。保持件的上述部分均可以视为与加热器31热接触的部分。
优选的实施中，加热器31的远端与底端盖30a之间保持密封，避免雾化生成的气溶胶从加热器31的远端与底端盖30a之间的间隙流向电源组件60中。
可选的实施中，座体可朝向插入口方向延伸，即凸出于自该座体朝向气溶胶生成装置100外径向延伸的部分。
可选的实施中，座体的内壁上具有多个间隔设置的凸棱；这样，在加热器31的远端保持在通孔中时，凸棱与加热器31的外侧壁抵接。这样，通过 设置的凸棱，减少了加热器31与底端盖30a的接触面积，避免加热器31的热量损失。
可选的实施中，加热器31靠近远端的部分可以具有一凸缘或者法兰，该凸缘或者法兰可以保持在通孔中。
管状体30b自底端盖30a的径向延伸的部分朝向气溶胶生成装置100的口端轴向或者纵向延伸，其延伸端(管状体30b的上端)可以超过加热器31的近端，具体的延伸长度在此不作限定。管状体30b的上端靠近插入口设置，管状体30b的下端靠近隔板63a设置。管状体30b与底端盖30a合围形成收容腔室，加热器31被收容或者保持在该收容腔室内；底端盖30a界定或者形成该收容腔室的底壁，管状体30b界定或者形成该收容腔室的侧壁。
可选的实施中，管状体30b上设置有通孔(未示出)和可遮蔽该通孔的遮蔽件。在气溶胶生成装置100出厂时，可通过该通孔进行校温，有利于提升气溶胶生成装置100的温度准确性。
固定臂30c自管状体30b朝向气溶胶生成装置100外径向延伸。隔热件40上端的端部形成或者界定支撑部，固定臂30c保持在该支撑部上。这样，固定臂30c夹持在支撑部与提取器20之间。在其它示例中，固定臂30c还可与支撑部卡扣连接。
延长臂30d大致呈管状。延长臂30d自固定臂30c朝向气溶胶生成装置100的底端轴向或者纵向延伸，其延伸端也可以超过加热器31的远端或者底端盖30a，具体的延伸长度也不作限定。
在本示例中，加热器31所采用的加热方式不作限定，例如电阻加热、电磁感应加热(与加热器31配套的感应线圈可套设在延长臂30d上)以及红外辐射加热等等，均可以适用。加热器31的形状也不作限定，可以是片状、针状等。
隔热件40优选的采用热传导系数较低的材料制成。隔热件40可以避免腔室A中的热量直接传递至外壳，导致外壳温度过高。
如图7所示，隔热件40包括管状的本体40a、自本体40a朝向远离本体40a方向延伸的连接部40b，连接部40b大致呈半管状或者具有较大的缺口。
装配后，保持件30的延长臂30d夹持在上壳体10的内侧壁与本体40a的外侧壁之间，进一步地，延长臂30d的外侧壁上设置有凸块，上壳体10的 内侧壁上设置有凹槽，通过凸块与凹槽的配合，延长臂30d可卡扣在上壳体10的内侧壁上；底端盖30a和管状体30b均被收容在本体40a内，本体40a上端的端部支撑固定臂30c。
底端盖30a和管状体30b均与本体40a之间沿气溶胶生成装置100的横向方向间隔设置形成间隙；其中，气溶胶生成装置100的横向方向包括气溶胶生成装置100的宽度方向或者厚度方向、或者倾斜于气溶胶生成装置100的宽度方向或者厚度方向；对于圆柱状的气溶胶生成装置100，气溶胶生成装置100的横向方向包括气溶胶生成装置100的径向方向、或者倾斜于气溶胶生成装置100的径向方向。
需要说明的是，底端盖30a与本体40a之间沿气溶胶生成装置100的横向方向间隔设置至少包括以下情形(管状体30b与此类似)：底端盖30a与本体40a之间没有直接或者间接接触；底端盖30a与本体40a之间通过隔热材料间接接触；底端盖30a与本体40a之间设置隔热材料，但底端盖30a与本体40a之间没有间接接触。
还需要说明的是，在其它示例中，隔热件40可采用其它材质制成的内壳体来替代，内壳体的形状可参考隔热件40及前述描述。
密封件50也夹持在上壳体10的内侧壁与本体40a的外侧壁之间；连接部40b夹持在下壳体61的内侧壁与支架63的外侧壁之间，且其下端端部抵接在支架63的外侧壁的台阶面上。
电源组件60包括大致呈管状的下壳体61，设置在下壳体61内的电芯62、支架63以及线路板64。
电芯62，用于提供电力；优选的实施中，电芯62为可充电电芯。
如图8所示，支架63包括隔板63a、第一收容腔室63b以及第二收容腔室63c。
装配后，隔板63a抵接在连接部40b的内侧壁的台阶面上，进而大致的将外壳内的空间分隔成上下两个空间，提取器20、保持件30、加热器31、隔热件40以及密封件50均布置在上空间内，而电芯62和线路板64布置在下空间内。在其它示例中，隔板63a也可以保持在连接部40b上；例如卡接在连接部40b上。
第一收容腔室63b用于收容或者装配震动马达(附图未示出)、线路板 64等等；第二收容腔室63c位于第一收容腔室63b的下方，用于收容电芯62等。
一般的，加热器31具有引线，例如：电极引线、温度传感器的引线。这些引线需要与电芯62电连接。隔板63a上还设置有过孔，过孔的数量可以为一个或者多个，例如：与引线的数量相同的多个过孔，加热器31的引线穿过过孔后可以与电芯62电连接。
替代的示例中，加热器31远端的端部可具有一电接触点，电源组件60内可设置一电连接件，该电连接件的一端穿过隔板63a的过孔后可以与电芯62电连接，该电连接件的另一端设置在隔板63a上形成另一电接触点，以与加热器31接触形成电连接。这样，保持件30和加热器31可一起装配至气溶胶生成装置100的外壳内或者从气溶胶生成装置100的外壳内移除；减少了气溶胶生成装置100的装配工序，提升了装配效率。上述电接触点之间可以是POGO PIN方式连接、卡接方式连接。上述电接触点之间还可以设置电连接转换件，以通过电连接转换件接触进而形成电连接。
线路板64用于气溶胶生成装置100的整体控制。
由以上可以看出，底端盖30a与隔板63a之间间隔设置形成间隙，没有固体介质的热传导路径(引线的横截面较小，热传导的热量可忽略不计)，由于底端盖30a和管状体30b均与本体40a之间沿气溶胶生成装置100的横向方向间隔设置形成间隙，也没有固体介质的热传导路径。这样，加热器31远端较高或者绝大部分的热量，沿着底端盖30a的延伸部分、管状体30b、固定臂30c，热传导至上壳体10；该热传导路径是远远大于底端盖30a的外侧壁与隔热件40的内侧壁之间的间隔距离，避免加热器31远端较高热量直接径向热传导至外壳，导致外壳温度过高的问题，提升了用户的使用体验。进一步地，由于较好地避免外壳温度过高的问题，气溶胶生成装置100的横向方向尺寸可以相对地减小，从而利于气溶胶生成装置100的小型化。优选的，气溶胶生成装置100的横向方向的尺寸为15mm～20mm；进一步优选的，气溶胶生成装置100的横向方向的尺寸为15mm～18mm；进一步优选的，气溶胶生成装置100的横向方向的尺寸为16mm～18mm。
可以容易想到的，加热器31远端较高的热量沿着管状体30b热传导，还有利于提升腔室A的热量。
通过固定臂30c和延长臂30d，保持件30可以保持在隔热件40内；另一方面，延长臂30d夹持在上壳体10的内侧壁与隔热件40的本体40a的外侧壁之间，可以固定保持件30的同时进一步降低热量传递至外壳。
在本示例中，底端盖30a、管状体30b、固定臂30c以及延长臂30d的材质均相同。替代的示例中，从加热器31传递至底端盖30a、管状体30b、固定臂30c的热量较高，传递至延长臂30d的热量较低，因此，底端盖30a、管状体30b、固定臂30c可采用耐温较高的材料，而延长臂30d可采用耐温较低的材料，即与其它部分的材料不同；这样，利于成本的控制。
进一步地，由隔板63a、隔热件40、固定臂30c、管状体30b、底端盖30a等围成的封闭空间，加热器31远端较高的热量还可能通过该封闭空间热传递至气溶胶生成装置100的外壳，例如：主要通过热对流或者热辐射方式进行热传递。在封闭空间密封性较好时，可以充入导热系数非常低的气体或者直接抽真空，进而使得封闭空间形成气槽或者真空槽；可选的实施中，可以在封闭空间内填其它充隔热材料，例如气凝胶。隔热材料可以与底端盖30a(或者管状体30b；或者固定臂30c)和/或隔热件40接触，也可以与底端盖30a(或者管状体30b；或者固定臂30c)和/或隔热件40均保持间隔；隔热材料可以与隔板63a接触或者保持间隔；由于隔热材料的导热系数非常低，在隔热材料与底端盖30a和隔热件40均接触的情形下，底端盖30a与本体40a之间的热传导的热量可忽略不计，即底端盖30a与本体40a之间仍是无固体介质的热传导路径或者热传导路径增大。这样，一方面可以避免加热器31远端较高量直接径向热传导至外壳，导致外壳温度过高的问题；另一方面，气溶胶生成装置100径向方向的尺寸可以减小，利于小型化。
可以理解的，在不设置隔热材料时，底端盖30a与隔热件40以及隔板63a均是没有直接或者间接的接触，即底端盖30a是悬空布置在上壳体10内，保持件30的下端也是悬空布置在上壳体10内的；此时，保持件30形成悬挂结构，保持件30被悬挂在支撑部上。
图9是本申请另一实施方式提供的气溶胶生成装置的剖面示意图。
与图1-图8示例不同的是，保持件30的管状体30b、固定臂30c以及延长臂30d一体形成，而底端盖30a与管状体30b之间是过盈配合连接的，底端盖30a密封管状体30b的下端端部。具体地，部分底端盖30a被收容在管状 体30b内，底端盖30a与管状体30b之间还通过密封件保持密封。
与图1-图8示例还有不同的是，底端盖30a一端的端部具有朝向支架63的隔板63a或者气溶胶生成装置的底端纵向延伸的延伸部(未示出)，该延伸部保持在隔板63a上。隔板63a上也可以设置朝向底端盖30a延伸的另一延伸部，以支撑底端盖30a。通过延伸部可以以较小的接触面积保持两者之间的连接，避免较多的热量传递至或者热传导至隔板63a。在一替代的实施中，底端盖30a一端不设置延伸部，底端盖30a一端的端部直接保持或者抵接在隔板63a上，也是可行的。
在图9的示例中，由于加热器31的远端固定在管状体30b下端处设置的固定孔中，加热器31远端较高的热量，可以沿着管状体30b、固定臂30c，热传导至外壳，还可以沿着底端盖30a的延伸部分、支架63、隔热件40，再热传导至外壳；无论哪一种热传导路径，均是大于底端盖30a的外侧壁与隔热件40的内侧壁之间的距离，避免加热器31远端较高量直接径向热传导至外壳，导致外壳温度过高的问题，提升了用户的使用体验。
图10-图14是本申请又一实施方式提供的气溶胶生成装置及其部件的示意图。
与图1-图8示例不同的是，保持件30的底端盖30a、管状体30b以及固定臂30c一体形成，而固定臂30c保持在延长臂30d上，即延长臂30d上端的端部形成或者界定支撑部，以支撑固定臂30c。
与图1-图8示例不同的是，保持件30的外表面还设置有凹槽30e，用于容纳第一电连接件(未示出)。凹槽30e布置在保持件30的底端盖30a、管状体30b以及固定臂30c上，且与第一电连接件的形状相匹配。加热器31中的引线可以直接焊接在第一电连接件的一端(布置在底端盖30a上)。气溶胶生成装置100还包括第二电连接件，第二电连接件沿着隔热件40布置。具体地，第二电连接件的一端与第一电连接件的另一端(布置在底端盖30a上)保持接触以形成电连接，第二电连接件的另一端穿过支架63的隔板63a上的过孔后与电芯62电连接。替代的示例中，隔热件40本身可以由导电材料制成；这样，隔热件40的上端与第一电连接件的另一端(布置在底端盖30a上)保持接触以形成电连接，隔热件40的下端穿过支架63的隔板63a上的过孔后与电芯62电连接。第一电连接件和第二电连接件均可以设置凸出的电接触 点，以便于彼此间保持接触形成电连接。
与图1-图8示例不同的是，保持件30的侧壁上还设置有通孔30f，提取器20的外侧壁上设置有凸块20a，上壳体10设置有磁性件10a；提取器20上端朝外径向凸出的部分固定在上壳体10上。装配后，凸块20a卡接在通孔30f内。初始时，由于磁性件10a与电连接件之间的磁吸力，保持件30保持在气溶胶生成装置100内。当用户往上拔出上壳体10时，上壳体10带动提取器20往上活动，凸块20a在通孔30f内往上活动；在凸块20a活动到通孔30f的上端时，凸块20a被限位，此时气溶胶生成制品200与加热器31脱离(或者部分加热器31仍是处于气溶胶生成制品200内)，第一电连接件与第二电连接件之间也是处于脱离接触状态。继续往上拔出上壳体10时，保持件30(除了延长臂30d外)可与提取器20以及上壳体10一起从气溶胶生成装置100上拆卸下来。
需要说明的是，在其它实施方式中，保持件30的底端盖30a、管状体30b、固定臂30c、延长臂30d中任意两者之间是分体形成的；或者，管状体30b和固定臂30c一体形成，底端盖30a与管状体30b之间是分体的，延长臂30d与固定臂30c之间是分体的，均是可行的。
图15-图17是本申请又一实施方式提供的气溶胶生成装置及其部件的示意图。
与图1-图8示例不同的是，保持件30的底端盖30a、管状体30b以及固定臂30c一体形成，可以通过模内注塑、双色注塑或者粘接等工艺固定或者一体形成；保持件30没有设置延长臂30d。保持件30和加热器31可整体装配至气溶胶生成装置100的外壳内或者从气溶胶生成装置100的外壳内移除。
具体地，底端盖30a包括座体、自座体朝向气溶胶生成装置100外(或者底端盖30a的外侧壁)径向延伸的延伸部。座体具有上敞口端、与所述上敞口端相对的下敞口端、以及自所述上敞口端延伸至所述下敞口端的固定孔。固定孔与加热器31远端的形状相匹配，加热器31靠近远端的外侧壁与固定孔的内壁抵接，加热器31的远端可以被收容在固定孔中或者延伸至所述下敞口端外。
管状体30b被构造成围绕至少部分腔室A、且沿腔室A的纵向或者轴向延伸的管状，底端盖30a的外侧壁上还设置有第一台阶。部分底端盖30a伸入 到管状体30b内，管状体30b下端抵接在该第一台阶上，管状体30b靠近其下端的内壁与底端盖30a的外侧壁接触；部分固定臂30c伸入到管状体30b内，管状体30b上端与固定臂30c外侧壁上的第二台阶抵接，管状体30b靠近其上端的内壁与固定臂30c的外侧壁接触。可以很容易想象得到的，管状体30b上端伸入到固定臂30c内，固定臂30c的内壁上设置台阶，也是可行的；与此类似的，管状体30b下端与底端盖30a，也是可行的。在其它示例中，底端盖30a上可以设置凹槽，管状体30b的下端可以卡接在该凹槽中；固定臂30c与此类似。
图18是本申请又一实施方式提供的气溶胶生成装置的剖面的局部放大示意图。
与图1-图8示例不同的是，加热器31被构造成围绕或者包裹至少部分气溶胶生成制品200进行加热，即通常所谓的周向加热或者外围加热方式。加热器31所采用的加热方式不作限定，例如电阻加热、电磁感应加热以及红外辐射加热等等，均可以适用。加热器31的形状也不作限定，例如可以被构造成围绕至少部分气溶胶生成制品200、且沿轴向方向延伸的管状结构，还例如可以为片状、半圆柱体状等等。
需要说明的是，上述空气加热方式，加热后的空气可以进入气溶胶生成制品200的底端，从而对气溶胶生成制品200进行加热；和/或，热空气的热量通过高导热材料传递至气溶胶生成制品200的侧壁，从而对气溶胶生成制品200进行加热。空气被加热的方式不作限定，可以是电阻加热、电磁感应加热以及红外辐射加热等。
与图1-图8示例不同的是，加热器31保持在管状体30b的下端处。具体地，加热器31下端的端部与保持件30的底端盖30a抵接，保持件30的管状体30b套设在加热器31外，加热器31可以与管状体30b直接接触、或者通过固定件与管状体30b接触；底端盖30a悬空设置在隔板63a上，即底端盖30a与隔板63a之间间隔设置形成间隙，没有固体介质的热传导路径；底端盖30a和管状体30b均与隔热件40的本体40a之间沿气溶胶生成装置100的横向方向间隔设置形成间隙，也没有固体介质的热传导路径。这样，加热器31较高或者绝大部分的热量，沿着管状体30b、固定臂30c，热传导至上壳体10；该热传导路径是远远大于管状体30b与隔热件40的内侧壁之间的距离，避免 加热器31较高热量直接径向热传导至外壳，导致外壳温度过高的问题，提升了用户的使用体验。
在其它示例中，加热器31下端端部的热量一般较低，底端盖30a可以保持在隔板63a上(例如，通过图9示例的情形)；这样，加热器31部分热量通过底端盖30a、支架63、隔热件40，再热传导至外壳；该热传导路径同样大于管状体30b与隔热件40的内侧壁之间的距离，同样可避免加热器31较高热量直接径向热传导至外壳，导致外壳温度过高的问题，提升了用户的使用体验。
图19是本申请又一实施方式提供的气溶胶生成装置示意图。
与图1-图8示例不同的是，加热器31包括空气加热部分31a和热传导部分31b。空气加热部分31a对流入的空气(虚线箭头所示)进行加热，生成的热空气可对气溶胶生成制品200进行烘烤；热传导部分31b采用高导热材料制成，热传导部分31b与空气加热部分31a连接；热传导部分31b升温后，将热量传递至气溶胶生成制品200的外周壁，对气溶胶生成制品200进行烘烤。
与前述类似的，保持件30被构造成保持加热器31，其具体结构和功能可参考前述内容。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施例，但是，本申请可以通过许多不同的形式来实现，并不限于本说明书所描述的实施例，这些实施例不作为对本申请内容的额外限制，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。并且，上述各技术特征继续相互组合，形成未在上面列举的各种实施例，均视为本申请说明书记载的范围；进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
