为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
图1-2所示为本发明第一实施例中的气溶胶产生装置，其大致可呈圆柱状并包括提取器1、沿纵向可分离地设置于提取器1上的主机2以及设置于主机2上的加热件22。该气溶胶产生装置可通过低温加热不燃烧的方式加热气溶胶产生基质3，形成可供用户抽吸的烟雾。可以理解地，该气溶胶产生装置并不局限于呈圆柱状，其也可以呈方形柱状等其他形状。在本实施方式中，气溶胶产生基质3可以为烟支。
提取器1在一些实施例中可包括第一壳体11以及呈圆环状并紧密地嵌置于第一壳体11底部的第一磁体13。第一壳体11的内壁面界定出一个用于收容气溶胶产生基质3的收容空间110，收容空间110的顶部敞开，收容空间110的底部形成有一底壁112，底壁112上开设有可供加热件22插入的插口111。气溶胶产生基质3可从收容空间110的顶部敞开口处插入到收容空间110中并抵靠在底壁112上。
主机2在一些实施例中可包括第二壳体21、加热件22、座体24以及第二磁体23。第二壳体21内可设置有电池和电路板等电子元器件，用于给加热件22供电以及控制整个气溶胶产生装置的开启或关闭等操作。
座体24可沿纵向嵌置于第二壳体21的上端，其包括圆筒状侧壁2411以及一体结合于侧壁2411顶部的圆板状的顶壁2412。侧壁2411的周向两侧分别向外凸出形成有一个卡台2413，第二壳体21的内壁面对应卡台2413凹陷形成有卡槽211，卡台2413、卡槽211相互扣合，从而将座体24扣合固定于第二壳体21内。座体24和第二壳体21之间采用插接和内扣连接的方式固定，方便可靠，且使得主机2的外部无扣位外露，更加美观。第二磁体23呈圆环状，其可紧密地嵌置于侧壁2411内并抵靠于座体24的下端面上。第一磁体13、第二磁体23可以为相互吸引的磁铁，或者也可以是其他具有磁性的元件（如铁钴镍）。
加热件22沿纵向嵌置于顶壁2412上，其可包括伸入到收容空间110中用于加热气溶胶产生基质3的加热部221。加热部221可从收容空间110底部的插口111伸入到收容空间110中并插入到气溶胶产生基质3内，对气溶胶产生基质3进行烘烤加热。加热件22可以为片状或棒状，加热件22的上端可设有尖头导向结构，利于插入到气溶胶产生基质3中。插口111的形状可与加热部221的横截面的形状相对应，且插口111的横截面尺寸可略大于加热部221的横截面尺寸，使得加热部221与插口111间隙配合，以利于加热部221的插入和退出，并可使加热部221与气溶胶产生基质3分离时，底壁112可通过摩擦作用刮去加热部221上的残余物质，例如粘结在加热部221上的加热后的气溶胶产成基质，对加热部221进行清洁。在本实施例中，加热件22为片状，插口111为横截面尺寸略大于加热部221的横截面尺寸的矩形。可以理解地，在其他实施例中，加热件22也可以以可拆卸可分离的方式设置于主机2上。
该提取器1具有与主机2对接的第一位置以及与主机2分离的第二位置。当提取器1和主机2对接时，第一壳体11、第二壳体21相互对接并抵靠在一起，第一壳体11底部的第一磁体13与第二壳体21顶部的第二磁体23相互靠近并吸附，通过第一磁体13、第二磁体23之间的吸力将提取器1和主机2相互固定，加热件22从提取器1底部的插口111伸入，使得加热部221完全伸入到收容空间110中。气溶胶产生基质3从提取器1顶部装入，主机2中的电池为加热件22供电，加热件22在通电发热后对气溶胶产生基质3进行烘烤加热（此时提取器1与主机2位于对接的第一位置）。
当气溶胶产生基质3被加热完后，通过向上拉动提取器1，第一磁体13即与第二磁体23相远离，提取器1与主机2即刻分离（此时提取器1与主机2位于分离的第二位置），此时，提取器1与主机2之间无连接，提取器1经由收容空间110的底壁112带动气溶胶产生基质3向上运动，使得加热部221从气溶胶产生基质3中退出，同时通过底壁112刮擦加热部221外部粘结的残余物质。
图3-4所示为本发明第二实施例中的气溶胶产生装置，该实施例与第一实施例的主要区别在于，在本实施例中，第一壳体11的顶壁向下延伸形成有一圆管状提取管12，提取管12的内侧壁界定出用于收容气溶胶产生基质3的收容空间110。此外，在本实施例中，座体24可包括嵌置于第二壳体21中的基部241以及由基部241的顶壁2412向上延伸形成的圆筒状的罩体243。罩体243罩设于加热件22外，可以在提取器1和主机2对接时防止因第一壳体11横向移动而抵压破坏加热件22。罩体243设置于第一壳体11和提取管12之间，并分别与第一壳体11的内壁面、提取管12的外壁面之间具有间隔。在一些实施例中，罩体243与第一壳体11的内壁面、提取管12的外壁面之间的间隔的距离分别可以为0.5~5mm，优选为3~5mm。
图5-7所示为本发明第三实施例中的气溶胶产生装置，该实施例与第二实施例的主要区别在于，在本实施例中，提取管12包括相互套接并可沿轴向相互滑动的固定管121和活动管122，固定管121和活动管122的内壁面共同界定出用于收容气溶胶产生基质3的收容空间110。
具体地，在本实施例中，固定管121以上端紧密地嵌置于第一壳体11的顶壁上，并可通过螺纹连接、卡扣连接等方式固定于第一壳体11上。活动管122可沿轴向上下滑动地套接于固定管121的下端外，活动管122的底壁形成收容空间110的底壁112。活动管122的顶部向内延伸形成有凸缘1221，固定管121的下端外圈向外延伸形成有凸台1211，凸缘1221、凸台1211相配合，可避免固定管121和活动管122在相互滑动时相脱离。在一些实施例中，活动管122相对于固定管121可滑动的行程为2.5~5.5mm，例如4.5mm左右。
主机2的上端外部可形成有第一卡接部，提取器1的底端内部形成有与第一卡接部相互卡接配合的第二卡接部，其中，第一卡接部的轴向长度小于等于活动管122相对于固定管121的滑动行程。具体地，在本实施例中，座体24可包括嵌置于第二壳体21中的基部241、由基部241的顶壁向上延伸形成的套接部242以及由套接部242的顶壁向上延伸形成的罩体243，基部241、套接部242、罩体243的内径和外径均依次递减。套接部242的外壁面形成第一卡接部，第一磁体13形成第二卡接部，当提取器1和主机2组装后，第一磁体13紧密地套接于套接部242外，从而可提高提取器1和主机2之间结合的稳固性。套接部242的轴向长度可小于等于活动管122相对于固定管121的滑动行程。在一些实施例中，套接部242的轴向长度可以为1~2.5mm，优选为2mm左右。在其他实施例中，提取器1和主机2之间也可不设置有第一磁体13、第二磁体23，通过提取器1和主机2相套接形成两者之间的连接，例如可将第一壳体11的底部直接套接于套接部242外，此时，第二卡接部可由第一壳体11底端的内壁面向内延伸形成。
套接部242上开设有可供加热部221穿过的穿孔2421，加热部221可依次穿过穿孔2421、插口111向上插入到气溶胶产生基质3中。在本实施例中，穿孔2421的横截面形状和尺寸与插口111的横截面形状和尺寸一致，在加热部221与气溶胶产生基质3分离时，穿孔2421的孔壁也可通过摩擦作用刮去加热部221上的残余物质。在其他实施例中，穿孔2421的横截面尺寸也可大于插口111的横截面尺寸。在另一些实施例中，穿孔2421的横截面形状也可与插口111的横截面形状不同。
以活动管122相对于固定管121的滑动行程为4.5mm、套接部242的轴向长度为2mm为例，如图5所示，当提取器1处于第一位置时，提取器1和主机2相互对接，此时，提取器1的第一磁体13套接于主机2的套接部242外并与第二磁体23相吸，活动管122的下端面抵靠于套接部242的顶壁上，固定管121的下端面抵靠于活动管122的底壁112上，气溶胶产生基质3从固定管121的顶部装入至抵靠于活动管122的底壁112上，加热件22的加热部221从活动管122底部的插口111伸入并插入到气溶胶产生基质3中，在通电发热后对气溶胶产生基质3进行烘烤加热。
当气溶胶产生基质3加热完后，先向上拉动第一壳体11，第一壳体11带动固定管121、第一磁体13向上运动，当向上运动的位移超过2mm时，第一磁体13与套接部242分离，从而使提取器1与主机2分离，此时，由于固定管121上的凸台1211还未上移至与活动管122上的凸缘1221接触，活动管122、气溶胶产生基质3、加热件22相对保持静止；如图6所示，继续向上拉动第一壳体11至位移达到4.5mm时，凸台1211向上移动至抵靠于凸缘1221上，此时，继续拉动第一壳体11，固定管121将带动活动管122一起向上运动，进而经由活动管122的底壁112带动气溶胶产生基质3向上运动；然后，继续向上拉动第一壳体11，使得气溶胶产生基质3与加热部221分离，如图7所示，同时还可通过底壁112刮擦加热部221外部粘结的残余物质。
如图8所示，该气溶胶产生装置在本实施例中还可包括嵌置于座体24中的内座25，内座25与座体24共同形成用于供加热件22插装并支撑提取器1的基座组件。第二磁体23可紧密地嵌置于内座25中，第一磁体13套设于套接部242外并与基部241的顶面之间形成有通气间隙130。内座25的上端面与套接部242的下端面之间形成有一围绕加热件22的气流通道240，套接部242的底部侧壁的两相对侧上分别开设有一与气流通道240相连通的通气孔2420。第一壳体11的侧壁底部的两相对侧分别形成有一进气孔120，外部空气可依次经由进气孔120、通气间隙130、通气孔2420进入到气流通道240中给基座组件降温，然后将带有热量的空气依次经由穿孔2421、插口111带入到收容空间110中的气溶胶产生基质3内，预加热后的空气还可提高雾化效率，还可使得气溶胶产生基质3内的温度分布更加均匀。
可以理解地，在其他实施例中，进气孔120也可开设于第二壳体21的侧壁或底壁上。第一磁体13的底面与基部241的顶面之间也可不形成有通气间隙130，只要气流可以从基座组件的表面流过给基座组件降温即可，例如，进气孔120也可开设于第二壳体21上并位于座体24和内座25之间，然后经由座体24和内座25之间的间隙进入到气流通道240中。气流通道240也可不围绕加热件22，例如，进气孔120也可开设于第二壳体21的底部，气流通道240沿纵向延伸且与加热件22的纵向平行。
可以理解地，上述各技术特征可以任意组合使用而不受限制。
以上实施例仅表达了本发明的优选实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制；应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，可以对上述技术特点进行自由组合，还可以做出若干变形和改进，这些都属于本发明的保护范围；因此，凡跟本发明权利要求范围所做的等同变换与修饰，均应属于本发明权利要求的涵盖范围。
