请参阅图1至图7所示，一种吸尘器滤芯漏装检测机构，包括：前滤芯10、后滤芯20及一个防漏装组件30。
后滤芯20与前滤芯10在正确安装后相互抵接，且后滤芯20与前滤芯10在拆卸时可分开拆卸。
一防漏装组件30，位于后滤芯20的顶部，在后滤芯20与前滤芯10均正确安装后，后滤芯20与前滤芯10共同抵压防漏装组件30，并触发防漏装组件30。
防漏装组件30包括：位于后滤芯20顶部的识别装置以及与识别装置连接或抵接的触发元器件32。
当后滤芯20与前滤芯10均正确安装后，识别装置可识别后滤芯20与前滤芯10抵接识别装置产生的压力或位移；当后滤芯20与前滤芯10中至少之一未安装时，识别装置识别不到压力或位移。
与识别装置连接或抵接的触发元器件32，用于当识别装置识别后滤芯20与前滤芯10抵接识别装置产生的压力或位移时，触发吸尘器开机；当识别装置识别不到压力或位移，吸尘器无法开机。
具体地，防漏装组件30包括：位于后滤芯20顶部的弹片31以及与弹片31抵接的触发元器件32。
当后滤芯20与前滤芯10均正确安装后，前滤芯10抵压后滤芯20，后滤芯20抵压弹片31产生位移，当后滤芯20与前滤芯10中至少之一未安装时，弹片31不产生位移。
当弹片31产生位移时，触动触发元器件32，触发吸尘器开机；当弹片31不产生位移，不会触动触发元器件32，吸尘器无法开机。
弹片31包括第一端311和第二端312；第一端311铰接与吸尘器内部的装饰盖41上，在后滤芯20与前滤芯10均正确安装后，后滤芯20抵压弹片31的第二端312，使第二端312产生位移，第二端312以第一端311的铰接轴为中心，做微小的弧形位移，第二端312抵压触发元器件32。触发元器件32为公知器件，在此不累赘。
在本发明中，仅仅设置一个触发元器件32，即可检测前滤芯10和/或后滤芯20的漏装。
防漏装组件30还包括回弹件33，回弹件33一端安装在吸尘器内部的装饰盖41上，一端抵 接后滤芯20；当前滤芯10拆卸或漏装时，回弹件33回弹使所述后滤芯20恢复不抵压触发元器件32的状态。
具体地，第二端312通过回弹件33安装在吸尘器内部的装饰盖上；回弹件33一端安装在吸尘器内部的装饰盖41上，另一端安装在弹片31的第二端312；当前滤芯10和/或后滤芯20拆卸或漏装时，回弹件33回弹使第二端312恢复不抵压触发元器件32的状态。
在本发明中，弹片31可以有至少两个，触发元器件32仅为一个。至少两个弹片31等间距安装在装饰盖41上。回弹件33安装在其中一个弹片31与装饰盖41上。
在本实施例中，参考图4-图5，装饰盖41、气流发生装置40中的机罩42均为圆筒状，为保证后滤芯20的受力平衡，设置三个弹片31，三个弹片31等距离分布。回弹件33安装在其中一个弹片31与装饰盖41之间。
在其他实施例中，防漏装组件30包括：位于后滤芯20顶部的压力传感器及与压力传感器连接的触发元器件32。具体地，可以在装饰盖41上设置压力传感器，用于识别后滤芯20与前滤芯10均安装后产生的压力。
当后滤芯20与前滤芯10均正确安装后，压力传感器可识别后滤芯20与前滤芯10抵接压力传感器产生的压力；当后滤芯20与前滤芯10中至少之一未安装时，压力传感器识别不到压力；与压力传感器连接的触发元器件32，用于当压力传感器识别后滤芯20与前滤芯10抵接压力传感器产生的压力时，触发吸尘器开机；当压力传感器识别不到压力，吸尘器无法开机。
前滤芯10位于电机43进风口，优选地，在旋风分离装置50临近电机43的进风口处设有容纳前滤芯10的容纳槽，前滤芯10位于容纳槽内。前滤芯10由过滤器介质层组成，过滤器介质层包括织物过滤器介质和/或非织物过滤器介质和/或静电过滤器介质。具体地，可以是粗纱和/或丝网层和/或绒等前滤芯10位于后滤芯20与旋风分离装置50之间。具体地，前滤芯10包括前滤网11、上边框12及下边框13；上边框12与下边框13一体成型组成边框，前滤网11固定安装在边框内。
在一实施例中，在前滤芯10安装后滤芯20与旋风分离装置50之间时，前滤网11抵接后滤芯20，下边框13抵接旋风分离装置50。
由于前过滤网11具有一定的厚度，本发明中定义，前过滤网11朝向上边框12的平面为前滤网正面111，前过滤网11朝向下边框13的平面为前滤网反面112。
前滤网11的前滤网正面111至上边框12顶部的距离L1小于前滤网11的前滤网反面112至下边框13底部的距离。以使当前滤芯10装反时，前滤网11抵接后滤芯20不足以抵压防漏装组件30，并触发防漏装组件30。
可以理解为：由于前滤网11的前滤网正面111至上边框12顶部的距离L1小于前滤网11的前滤网反面112至下边框13底部的距离。当前滤芯10方向安装正确时，前滤网11的前滤网正面111抵接后滤芯20，前滤芯10和后滤芯20均安装后，方可对弹片31施压产生位移。当前滤芯10方向装反时，前滤网11的前滤网反面112抵接后滤芯20，前滤芯10和后滤芯20均安装后，前滤芯10抵压后滤芯20，使后滤芯20产生的位移不足以对弹片31产生位移，或前滤网反面112至弹片31的距离，不足以触动触发元器件32。
本发明通过对前滤网11的前滤网正面111至上边框12顶部的距离L1小于前滤网11的前滤网反面112至下边框13底部的距离的设定，可以有效避免前滤芯10装反。且不会增加前滤芯10的其他部件。
在另一实施例中，在前滤芯10安装后滤芯20与旋风分离装置50之间时，上边框12抵接后滤芯20，下边框13抵接旋风分离装置50。上边框12或下边框13设有防止方向装反的标识，例如图像文字标识、凹凸不平的手感标识、拉手标识、微小手柄标识等。同样可以避免前滤芯10装反。
后滤芯20安装在气流发生装置40内，后滤芯20的一端抵接防漏装组件30，后滤芯20的另一端抵接前滤芯10。
气流发生装置40包括装饰盖41、机罩42、电机43及上壳体44，常规的气流发生装置40均如此设置，在此不多累赘。机罩42及电机43固定安装在装饰盖41上，外部套上壳体44。机罩42上设有孔洞。机罩42及电机43为圆筒状，后滤芯20为圆筒状，安装在机罩42与电机43之间，对进入气流发生装置40的气体进行二次过滤。
后滤芯20抵接防漏装组件30的一端设有电机保护件21，以防止后滤芯20装反。电机保护件21为镂空的骨架结构。后滤芯20包括上部的圆筒状的第一固定件、下部的圆筒状的第二固定件及固定在第一固定件与第二固定件的过滤介质。电机保护件21一体成型于第二固定件。同时，电机保护件21还起到防止后滤芯20装反的功能。
后滤芯20由高效能微粒空气过滤器介质组成，对进入过滤器中的空气进行二次过滤。
相应地，本发明还提供一种吸尘器，包括如上任一项的吸尘器滤芯漏装检测机构、气流发生装置40、旋风分离装置50及手柄组件60。旋风分离装置50位于下壳体51内，且旋风分离装置50设有吸尘口511，用于吸尘。
前滤芯10安装在旋风分离装置50的安装腔内，且安装后前滤芯10抵触后滤芯20，后滤芯20安装在气流发生装置40内。前滤芯10与后滤芯20均正确安装后，后滤芯20抵压弹片31，弹片31产生位移触动触发元器件32，以实现前滤芯10与后滤芯20的漏装检测。
本发明中的前滤芯10和后滤芯20为分开装配，非一体式的结构方便更换前滤芯10或后滤芯20；本发明通过在后滤芯的顶部设置一个防漏装组件，即可实现对前滤芯10和/或后滤芯20漏装的检测，当前滤芯10及后滤芯20中的其中之一漏装时，仅用一个防漏装组件均可检测任何一个的漏装；且本发明在前滤芯10和后滤芯20的结构上做了改进，可有效避免前滤芯及后滤芯的装反。
上述仅为本发明的一个具体实施方式，其它基于本发明构思的前提下做出的任何改进都视为本发明的保护范围。
