如图4所示，上述中盖5安装于底座1上，可以是在中盖5上设置若干插接部54，在底座1上设有卡槽，上述插接部54插接与卡槽内，来实现中盖5与底座1的连接。本实施例中，上述插接部54可以是在中盖5底部延伸而出的凸起。
在中盖5上设有风道，该风道能够连通于上述吸气通道，并且该风道末端设有上述出风口9。进入吸气通道的空气能够经该风道流出出风口9。在中盖5的中间位置开设有孔，该孔用于给电机2的机身提供安装空间。
可参照图5和图6，在中盖5上开设有进气口51，该进气口51连通于上述自清洁通道，外界空气能够从该进气口51进入自清洁通道。本实施例中，优选的，在该进气口51的底部设有上述插接部54，一方面实现中盖5与底座1的连接，另一方面能够提高进气口51的连接强度，实现对进气口51的支撑。
可选地，还可以在该进气口51处设置一封板52，该封板52能够启闭进气口51，具体是在吸尘器正常工作状态(也就是吸尘工作状态)时，封板52关闭进气口51；在吸尘器处于自清洁状态时，封板52打开进气口51，进行自清洁作业。
于本实施例中，上述封板52可以通过在两侧设置转轴522，在中盖5上设置支座55，通过将转轴522转动设置在支座55上，能够实现封板52相对于中盖5的转动，进而通过封板52的转动，能够实现对进气口51的启闭。进一步地，在封板52的一端还可以设置按压部521，该按压部521穿过上盖6的一个开口外露于中盖5外，通过按压该按压部521，能够使得封板52以转轴522为中心转动，进而封板52的另一端抬起，以打开进气口51。当抬起按压部521，封板52的另一端则下落并封闭进气口51。
为了实现封板52对进气口51的自动封闭，本实施例还设有复位机构，该复位机构可以是图5所示的弹性板53，该弹性板53固接于封板52的下方，并且该弹性板53具有一定的弹性形变，当按压部521被按压时，该弹性板53抵接于中盖5的上表面，并产生弹性形变，当不再按压按压部521时，弹性板53的弹性形变会驱动弹性板53以及其连接的封板52复位，此时封板52的另一端会被带动封闭进气口51。
可以理解的是，本实施例的上述复位机构还可以是其他能够实现封板52转动复位的结构，例如可以是套设在转轴522上的扭簧(图中未示出)，该扭簧一端抵接或固接于封板52，另一端抵接或固接于中盖5，当按压部521被按压时，扭簧被压缩，当不在按压按压部521时，扭簧会驱动封板52转动，以使得封板52的另一端封闭进气口51。
本实施例中，除了上述封板52配合按压部521以及复位机构的结构来实现对进气口51的封闭外，还可以采用其他方式驱动封板52封闭进气口51，例如直接采用滑轨配合封板52，通过抽拉封板52，使得封板52沿滑轨滑动，并能够使得封板52的一端启闭进气口51。只要能够实现封板52启闭进气口51的结构，均在本实施例的保护范围内。
作为优选地技术方案，本实施例中，在上述中盖5与电机2之间还设有减振密封件7，具体的是中盖5形成风道的一个侧壁与电机2的叶轮腔室21之间设置该减振密封件7，该减振密封件7可以采用唇形密封圈，其能够实现中盖5与电机2之间的密封，使得经电机2的叶轮腔室21流出的空气进入底座1与叶轮腔室21形成的部分吸气通道后，能够经出风口9流出。
本实施例中，如图4所示，上述电机托盘3中空设置，该电机托盘3的一端连通于过滤组件11内部，另一端连通于电机2的叶轮腔室21的输入口。外界空气经底座1进入并经过滤组件11过滤后，从过滤组件11内部流入叶轮腔室21的输入口。
上述电机托盘3搭接于底座1上，示例性地，可参照图7，可以在电机托盘3外侧中部设置若干支撑筋32，该支撑筋32可以提高该电机托盘3的强度。此外，可以在底座1上设置搭接槽13，该搭接槽13具体为开设于底座1上的弧形槽或环形槽，且该弧形槽或环形槽的截面为L形，上述电机托盘3的边缘能够搭接于该搭接槽13，通过该搭接槽13来支撑电机托盘3的边缘。
本实施例中，上述电机托盘3呈喇叭状或圆锥状，该喇叭状或圆锥状结构，能够使得电机托盘3在较小尺寸的前提下，能够与底座1之间形成自清洁通道。进一步地，在电机托盘3的边缘处还设有一连接板31，该连接板31可以与电机托盘3一体成型。通过该连接板31，能够使得电机托盘3与底座1之间形成图8所示的配合结构，即底座1上设有一自清洁口12(图2和图8所示)，该自清洁口12为自清洁通道的一部分，且该自清洁口12的一侧壁上设有一搭接部121，该搭接部121能够搭接于连接板31的端部。
上述底座1呈大致圆筒状结构，其可安装上述过滤组件11，且该底座1设有进风口(图中未示出)，该进风口用于供外界空气及灰尘进入。本实施例中， 电机托盘3包含内壁及外壁，该内壁包围出电机托盘3的中空部分，以此，上述底座1内壁与过滤组件11之间的部分、电机托盘3的中空部分、电机2的叶轮腔室21、底座1的自清洁口12的侧壁与叶轮腔室21的外壁之间的空间共同构成了上述吸气通道；上述电机托盘3外壁和底座1内壁之间的空间、上述底座1的自清洁口12共同形成了上述自清洁通道，且该自清洁通道的出气口设置于过滤组件11的内侧，进而能够实现对过滤组件11外壁上的灰尘杂物的清理。
进一步地，所述底座1、所述电机2及所述电机托盘3形成有配接间隙，密封件4设于所述配接间隙内，以对所述配接间隙进行密封。具体到本实施例中，由于上述电机托盘3的边缘与搭接槽13之间，搭接部121与连接板31的端部之间、电机托盘3与电机2之间以及电机2与底座1之间均会形成间隙，因此，本实施例设置了密封件4，来对上述各间隙进行密封。如图7和图8所示，该密封件4呈圆环形结构，且其截面呈L形，该密封件4的底部设置于电机2和电机托盘3之间，也就是电机2的叶轮腔室21部分置于该密封件4的底部上，以实现电机托盘3与电机2之间的密封，即吸尘器工作时，带有灰尘的气流无法通过电机托盘3及电机2之间的间隙。同时该密封件4的底部贴设于电机托盘3的边缘与搭接槽13的搭接处，实现两者的密封；该密封件4的侧部贴设于搭接部121与连接板31端部的搭接处，实现两者的密封；以此，吸尘器处于自清洁状态时，气流无法通过电机托盘3与底座1之间的间隙，从而不会有气流直接从电机托盘3及底座1之间的间隙流入电机托盘3的中空部分，吸尘器可以高效地进行自清洁作业。本实施例中，上述密封件4优选可以采用唇型密封圈。
需要说明的是，本实施例的上述密封件4在起到密封作用的同时，还能够 实现对电机2的减振，以降低噪声。以及实现对电机2的纵向定位以及对电机托盘3的固定，不需要采用螺钉等连接件即可实现对电机托盘3以及电机2进行固定，降低了加工成本以及人工成本。
可选地，本实施例在电机2的叶轮腔室21的输出口处还设有湿气吸收部8，该湿气吸收部8能够降低吸入的空气的湿度。优选地，上述湿气吸收部8可以是海绵，也可以是其它能够实现对湿气吸收的结构。本实施例的上述湿气吸收部8还可以周向覆盖于叶轮腔室21的外侧。
本实施例的上述电器在进行吸尘工作时，此时封板52封闭进气口51，启动电机2，外界含有灰尘杂物的空气被吸入底座1，并经过滤组件11过滤后流入电机2的叶轮腔室21，随后经底座1的自清洁口12的侧壁与叶轮腔室21的外壁之间的空间进入中盖5的风道内，并最终从出风口9流出。
在进行自清洁工作时，首先关闭底座1上的进风口，随后启动电机2，通过按压按压部521，外界空气能够进入进气口51，并经自清洁通道流至过滤组件11的内侧，外界空气撑起滤网，以使得附着于过滤组件11上的灰尘杂物落下，在此过程中，可以间隔按压按压部521，使得外界空气形成脉冲气流，以更好的实现对过滤组件11上的灰尘杂物的抖落。
显然，本实用新型的上述实施例仅仅是为了清楚说明本实用新型所作的举例，而并非是对本实用新型的实施方式的限定。对于所属领域的普通技术人员来说，能够进行各种明显的变化、重新调整和替代而不会脱离本实用新型的保护范围。这里无需也无法对所有的实施方式予以穷举。凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型权利要求的保护范围之内。
