Description

气溶胶产生装置 技术领域
本发明涉及雾化领域，更具体地说，涉及一种气溶胶产生装置。
 背景技术
加热不燃烧型雾化装置，是一种通过低温加热不燃烧的方式加热雾化材料形成可抽吸气雾的气溶胶产生装置。目前，加热不燃烧型雾化装置通常采用将加热器如加热片插入到气溶胶形成基质进行加热，通过控制加热温度，使得气溶胶形成基质中的成分挥发，产生气雾供人吸取。
当一支气溶胶形成基质加热到一定时间，其所产生的气雾量到达上限后，需要将气溶胶形成基质从雾化装置中拔出，或停止抽吸，或更换新的气溶胶形成基质继续抽吸。此时，如何将气溶胶形成基质方便、快捷地从雾化装置中拔出，并且不损坏气溶胶形成基质、在加热器上无残余物，便成为一个至关重要的问题。现有的加热不燃烧型雾化装置，一般通过手动拉拔的方式，将气溶胶形成基质从雾化装置中取出。由于使用者用力大小不同，拉拔力度也相差很大，很多使用者在拉拔时往往会造成气溶胶形成基质断裂、或者气溶胶形成基质与加热器接触部分产生黏连而在加热器上形成残余物，影响下次使用的加热效果，例如产生焦味。

 本发明的实施方式
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1-6示出了本发明第一实施例中的气溶胶产生装置100，该气溶胶产生装置100可用于对插接于其中的气溶胶形成基质200进行低温烘烤加热，以在不燃烧的状态下释放气溶胶形成基质中的气溶胶提取物。该气溶胶形成基质200可呈圆柱状并包括雾化段201，该雾化段201可包括植物叶类的固态基质。进一步地，气溶胶形成基质200还可以包括沿纵向依次设置于雾化段201上方的中空支撑段202、降温段203及过滤段204。该气溶胶产生装置100大致可呈方形柱状，气溶胶产生装置100的顶部设有形状和尺寸与气溶胶形成基质200相适配的插入口210。可以理解地，该气溶胶产生装置100并不局限于呈方形柱状，其也可以呈圆柱状、椭圆柱状等其他形状。
该气溶胶产生装置100可包括主机1以及沿纵向可分离地设置于主机1上方的提取器2。其中，提取器2的内部形成有用于收容气溶胶形成基质200的收容空间220，气溶胶形成基质200可经由插入口210插入到收容空间220中。主机1可包括机身11、设置于机身11的加热体14、设置于机身11内的主板16以及设置于机身11内的电池17。主板16分别与电池17和加热体14电连接。主板16上布置有相关的控制电路，可借由设置于机身11上的开关19启动主板16控制电池17供电给加热体14。加热体14的上端能够伸入到收容空间220中并插入到气溶胶形成基质200中，与气溶胶形成基质200紧密接触。加热体14在通电发热后，可以将热量传递给气溶胶形成基质200，从而实现对气溶胶形成基质200的烘烤加热。加热体14可以为电阻加热体，或者也可以为能够在变化磁场中产生热量的金属感应发热体。加热体14可以呈片状或棒状，加热体14的上端可设有尖头导向结构，利于插入到气溶胶形成基质200中。
该提取器2可包括可分离地套设于机身11的上盖21、设置于上盖21中的收容组件22以及设置于上盖21中的弹性组件23。当提取器2处于与机身11连接的状态时，气溶胶形成基质200位于能够被加热体14加热的第一位置。当提取器2处于与机身11分离的状态时，加热体14至少部分从收容空间220中脱出，使气溶胶形成基质200位于至少部分与加热体14分离的第二位置。该弹性组件23用于在提取器2与机身11由连接到分离的过程中改变收容空间220的长度。
具体地，收容组件22可包括位于上方并与上盖21固定连接的固定管221以及位于下方并且可滑动地套接于固定管221的活动管222，固定管221、活动管222的内壁面共同界定出收容空间220。活动管222沿纵向可滑动地套设于固定管221的下部，并可与固定管221同轴设置。活动管222包括一底壁2221，该底壁2221可用于支撑气溶胶形成基质200，气溶胶形成基质200可经由插入口210插入到收容空间220中并抵靠在底壁2221上。底壁2221上开设有可供加热体14穿过的插口2220，插口2220的形状可与加热体14的横截面的形状相对应，且插口2220的横截面尺寸可略大于加热体14的横截面尺寸，使得加热体14与插口2220间隙配合，以利于加热体14的插入和退出，并可使加热体14与气溶胶形成基质200分离时，底壁2221可通过摩擦作用刮去加热体14上粘结的残余物质，对加热体14进行清洁。在本实施例中，加热体14呈片状，插口2220为横截面尺寸略大于加热体14的横截面尺寸的矩形。加热体14的下端可嵌置于发热座15中，再经由发热座15插装于机身11的顶部。
固定管221可通过螺纹连接、卡扣连接、磁吸连接等方式与上盖21的顶壁内侧固定连接，活动管222可滑动地套接于固定管221内。在其他实施例中，固定管221也可与上盖21一体成型，例如，固定管221也可由上盖21的顶壁内侧沿纵向一体向下延伸形成。固定管221和活动管222上还可设置有相互配合的限位结构，以防止两者在滑动时脱离。在一些实施例中，该限位结构可包括位于下方并可由固定管221的内壁面沿径向向内延伸形成的第一限位凸起2213以及位于上方并可由活动管222的外壁面沿径向向外延伸形成的第二限位凸起2223。弹性组件23的两端分别与固定管221、活动管222连接，弹性组件23的上端可抵靠于第二限位凸起2223上，下端可抵靠于第一限位凸起2213上。弹性组件23能够使收容组件22在未插入气溶胶形成基质200的时候保持活动管222不会发生移动。
固定管221在一些实施例中可包括外管2211以及套设于外管2211中的内管2212。活动管222可滑动地套接于外管2211中，外管2211的下端沿径向向内延伸形成第一限位凸起2213。外管2211的内径可大于内管2212的外径。
活动管222在一些实施例中可包括位于下部的第一管段2222以及位于上部并与第一管段2222相连的第二管段2224。第二管段2224可滑动地套设于外管2211和内管2212之间。第二管段2224的外径大于第一管段2222的外径，并与外管2211的内径相适配，亦即，第二管段2224的外壁面与外管2211的内壁面滑动接触配合。第二管段2224、第一管段2222之间形成的台阶面形成第二限位凸起2223。外管2211的内壁面和第一管段2222的外壁面之间形成有一供弹性组件23安装的安装空间。弹性组件23可以为弹簧并套设于外管2211的内壁面和第一管段2222的外壁面之间。
第一管段2222的内径可与内管2212的内径相等或大致相等，第一管段2222沿轴向设置于内管2212的下方。第二管段2224的内径与内管2212的外径相适配，亦即，内管2212的外壁面可与第二管段2224的内壁面滑动接触配合。第二管段2224和内管2212上还可设置有至少一个相互配合的限位导向结构，用于在活动管222滑动时导向，并限制活动管222和内管2212之间的相对周向位置。在本实施例中，限位导向结构有两个，该两个限位导向结构分别位于收容空间220的两相对侧。该限位导向结构可包括沿纵向延伸的导向槽2225以及可滑动地配合于导向槽2225中的导向凸起2214。具体地，在本实施例中，导向槽2225贯穿地开设于第二管段2224上并可由第二管段2224的顶壁向下延伸至其底部附近，导向凸起2214由内管2212的外壁面向外延伸形成。导向凸起2214可以有两个，该两个导向凸起2214分别与导向槽2225的周向两侧滑动接触配合。导向槽2225的轴向长度大于活动管222相对于固定管221的最大滑动行程，避免上盖21与机身11分离时导向凸起2214从导向槽2225中脱出。在其他实施例中，导向凸起2214也可仅有一个，该一个导向凸起2214的周向两侧分别与导向槽2225的周向两侧滑动接触配合。
机身11的上端形成有一导向部181，上盖21的下端可滑动地套设于导向部181上，上盖21的内壁面与导向部181的内壁面滑动接触配合，该导向部181可在上盖21与机身11从连接状态移动至分离状态的过程中起导向作用。当上盖21与导向部181处于滑动接触配合时的任意位置时，气溶胶形成基质200位于能够被加热体14加热的第一位置。当上盖21与导向部181处于滑动接触分离时的任意位置时，气溶胶形成基质200位于至少部分与加热体14分离的第二位置。导向部181的轴向高度H0小于等于活动管222相对于固定管221的最大滑动行程，在本实施例中，导向部181的轴向高度H0与活动管222相对于固定管221的最大滑动行程相等。导向部181的顶部还可向上延伸形成有筒罩182，筒罩182罩设于加热体14外，筒罩182可以在上盖21和机身11对接时防止因上盖21横向移动而抵压破坏加热体14。筒罩182设置于上盖21和外管2211之间，并分别与上盖21的内壁面、外管2211的外壁面之间具有间隔。具体地，导向部181与筒罩182均为中空的筒状且相连，导向部181的外侧横截面尺寸大于筒罩182的外侧横截面尺寸，并对应于上盖21的内侧横截面尺寸，亦即，筒罩182的外侧横截面尺寸小于上盖21的内侧横截面尺寸。该导向部181内还可形成有一支撑臂183，支撑臂183的上端面可支撑收容组件22，或者也可与收容组件22的下端面之间形成有间隔。支撑臂183的下端面可抵压于发热座15上，从而固定发热座15。
如图4所示，上盖21和机身11相互对接，此时，上盖21套接于导向部181外与导向部181接触，上盖21的下端与导向部181的配合高度为导向部181的轴向高度H0，上盖21的下端面抵靠于机身11的上端面上，加热体14的上端穿过活动管222的底壁2221而伸入到收容组件22内。弹性组件23呈半压缩状态，以使活动管222的上端面弹性抵紧于内管2212的下端面上，避免活动管222晃动。在没有使用的状态下，即收容组件22内没有插入气溶胶形成基质200时，收容组件22的总长度为初始长度L0，即为内管2212和活动管222的长度之和。
在需要抽吸时，向收容组件22内插入气溶胶形成基质200，气溶胶形成基质200的底部被加热体14刺入，并且气溶胶形成基质200的底部抵靠于活动管222的底壁2221上，加热体14在通电发热后对气溶胶形成基质200进行烘烤加热。在气溶胶形成基质200的插入过程中，通常由于气溶胶形成基质200的插入力很小，不会推动活动管222下移，收容组件22的总长度保持为初始长度L0。当气溶胶形成基质200的插入力较大时，气溶胶形成基质200有可能推动活动管222的底壁2221使活动管222向下移动微小距离，使收容组件22的总长度略微增加一点后再恢复到初始长度L0。
当气溶胶形成基质200加热完后，拔动上盖21朝远离机身11的方向向上运动。在上盖21向上运动的过程中，上盖21的下端与导向部181的配合高度逐渐减小；另一方面，固定管221随着上盖21向上运动，活动管222和气溶胶形成基质200不移动，固定管221的第一限位凸起2213向上移动进一步压缩弹性组件23，收容组件22的总长度逐渐增加，气溶胶形成基质200和加热体14没有相对位移。如图5所示，当上盖21与机身11刚好分离时，上盖21的下端与导向部181刚好分离，即上盖21与导向部181相对滑动H0，同时，固定管221相对于活动管222也滑动了H0的高度，收容组件22的总长度从L0变为L0+H0。如图6所示，当上盖21继续向上时，活动管222也会随着上盖21向上运动，活动管222的底壁2221推动气溶胶形成基质200向上运动与加热体14分离。
上盖21的顶部还可设置有一个用于遮挡或显露插入口210的防尘盖25。在不需要使用气溶胶产生装置100时，可推动防尘盖25将插入口210遮挡住，防止灰尘进入到插入口210。在需要使用时，推动防尘盖25将插入口210露出，以便气溶胶形成基质200从插入口210插入。
图7示出了本发明第二实施例的气溶胶产生装置100，其与第一实施例的主要区别在于，在本实施例中，活动管224可滑动地套设于固定管223外。相应地，在本实施例中，弹性组件23套装于活动管224的内壁面和固定管223的外壁面之间。与弹性组件23的下端相抵靠的第一限位凸起2231可由固定管223的外壁面沿径向向外延伸形成，与弹性组件23的上端相抵靠的第二限位凸起2243可由活动管224的内壁面沿径向向内延伸形成。
具体地，在本实施例中，活动管224可包括位于下部的第一管段2241以及位于上部的第二管段2242。第二管段2242的外径和内径可分别大于第一管段2241的外径和内径。固定管223可滑动地设置于第二管段2242中，固定管223的下端可分离地抵靠于第二管段2242和第一管段2241之间形成的台阶面上。固定管223的内径可与第一管段2241的内径一致，以使上盖21和机身11相互对接时 ，收容空间220的内壁面平滑过渡。第二管段2242的内径大于固定管223的内径，弹性组件23套装于第二管段2242的内壁面和固定管223的外壁面之间。第一限位凸起2231可由固定管223的下端外壁面沿径向向外延伸形成，第二限位凸起2243可由第二管段2242的上端内壁面沿径向向内延伸形成。
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具体实施方式，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。
