Description

吸尘器电机减震结构 技术领域
本发明涉及减震结构领域，特别涉及一种吸尘器电机减震结构。
背景技术
吸尘器在使用过程中电机内罩中的电机高速旋转，在密封的壳体内产生空气负压，吸取外部尘屑的装置。
现有一种吸尘器包括具有一个进风孔与一个出风孔的壳体、一个装设于该壳体内的电机，及一个装设于该壳体内且位于该电机前方的尘袋和过滤装置，当该电机运转时，可将空气连同灰尘从进风孔经过尘袋吸入到壳体内，这样灰尘受该过滤装置阻拦即会停留于壳体内，而空气经电机推送即可从排风孔排出，电机在运行过程中使电机内罩产生振动，电机内罩进而带动与之接触连接的电机外罩发生振动，而且在振动的传递过程中，由于共振的作用，导致传递给电机外罩以及吸尘器外壳振动量更大，这就使得吸尘器整机的工作噪音很大，当使用者用手触摸吸尘器外表面时，还会有“麻手”的感觉，降低了用户的体验，而现有的常规吸尘器在降低振动方面没有革新的方案，效果也没有很大的改善。有鉴于此，是有必要开发一种吸尘器电机减震结构，用以解决上述问题。

具体实施方式
下面结合附图对本发明做进一步的详细说明，本发明的前述和其它目的、特征、方面和优点将变得更加明显，以令本领域技术人员参照说明书文字能够据以实施。
图1示出了使用了根据本案所述的吸尘器电机减震结构100的吸尘器的剖视图。
如图1、图2及图3所示，吸尘器电机减震结构100包括：电机安装罩110、内罩120、外罩130、以及弹性结构170，其中，电机安装罩110内部装有电机400，电机安装罩110的上端配接有吸尘器叶轮300，且吸尘器叶轮300设于内罩120的内部，吸尘器叶轮300由电机400所驱动，内罩120及外罩130从内之外依次套设在电机安装罩110之上，内罩120在其顶部敞开，内罩120的底壁121四周设有至少三个弹性结构170，电机安装罩110由弹性结构170弹性支撑并架空。吸尘器壳体200容纳电机安装罩110、内罩120、外罩130、吸尘器叶轮300、及电机400。在优选的实施方式中，弹性结构170的数量为奇数个；研究发现，从减震效果来看，三个及三个以上的奇数个弹 性结构170所形成的减震效果(轴向、径向以及绕轴向旋转的方向上的减震效果)要优于三个以上的偶数个弹性结构170所形成的减震效果。
如图6所示，外罩130包括：
随着半径扩大而逐渐倾弯曲向下的顶壁132；以及
裙部131，该裙部131在顶壁132的外周一体式地结合该顶壁132并且从该顶壁132的外周竖直向下延伸，
其中，顶壁132的中央区域开设有进气口。在一实施方式中，裙部131的下部开设有依次穿过外罩130的裙部131及内罩120的侧壁后通往内罩120内部的出气道133。
如图1及图6所示，外罩130的顶壁132与内罩120之间设有密封罩140，所述密封罩140的形状和尺寸配合到内罩120的敞口处。
如图1、图10、图11及图12所示，该密封罩140包括：
随着半径扩大而逐渐弯曲向下的端壁141；
竖直部142，该竖直部142在端壁141的外周一体式地结合该端壁141并且从该端壁141的外周竖直向下延伸；以及
水平部143，该水平部143在竖直部142的外侧一体式地结合该竖直部142并且从该竖直部142的外侧径向地向外延伸。在优选的实施方式中，密封罩140由弹性材料制成。此外，端壁141的中央区域开设有吸气口144，该吸气口144的边缘141a处设有翻边145，该翻边145在吸气口144的边缘141a处一体式地结合端壁141并且沿所述吸气口144的径向向外扩展，翻边145与端壁141之间具有一定距离从而形成卡接槽145a。
如图6及图11所示，顶壁132的进气口卡入到端壁141的卡接槽145a中，翻边145的下表面与顶壁132紧密贴合。如图12所示，顶壁132与裙部131的相接处设有竖直向下延伸的肩部134，肩部134与水平部143相接触并且由该水平部143所支撑，水平部143由内罩120所支撑，竖直部142的外侧与内罩120的侧壁紧密贴合。从而实现内罩120与外罩130之间缝隙的密封，使得带有杂质的空气经由吸气口144吸入后，导入到电机安装罩110的内部的过程中不发生泄露，同时由弹性材料制成密封罩140可以缓冲内罩120与外罩130之间的冲击力及震动，有利于保持整机的稳定性。
如图4、图5所示，电机安装罩110在其顶部敞开，电机安装罩110在其底部的中央区域开设有方形通孔114，电机安装罩110在其侧壁上开设有至少一个出气口，电机安装罩110的侧壁外侧设有数目与弹性结构170的数目相对应的支撑柱。在一实施方式中，电机安装罩110由两个半环形的左半支架111及右半支架112相合而成，在左半支架111及右半支架112相合缝隙处通过多个卡扣113将两者进行加固，左半支架111的侧壁上开设有出气口111a，左半支架111的侧壁外侧固接有多个支撑柱111b。在优选的实施方式中，左半支架111及右半支架112互为镜像，即右半支架112的侧壁上开设有出气口112a，右半支架111的侧壁外侧固接有多个支撑柱112b，支撑柱112b与支撑柱112b的总数与弹性结构170的数目相等。电机安装罩110采用这种可拆卸的结构，便于将电机装入电机安装罩110内。
参照图3、图5、图7及图8，电机安装罩110的底部上覆盖有平板状的电机压座160，电机压座160的基体161上设有至少两个向上凸起的止位柱162，止位柱162用于嵌入电机底部相应的凹槽中，从而对电机起到可拆卸固定的作用，电机压座160的中央区域设有用于容纳电机转轴末端的腔体163。在优选的实施方式中，电机压座160及腔体163均由弹性材料制成。腔体163贯穿电机压座160并穿过方形通孔114后向下凸出，电机压座160的下表面固接有形状及大小与方形通孔114相匹配的方形止位块164，方形止位块164套接于腔体163的外表面，方形止位块164卡接于方形通孔114中从而限制了电机压座160的转动。在一实施方式中，腔体163的底部距离内罩120的底壁121具有一定的距离。
如图9所示，弹性结构170包括：
弹片主体171；以及
分别与弹片主体171的上端171a及下端171b一体式相连的直角固定件172，
其中，直角固定件172包括互成90度夹角的水平段及竖直段，所述水平段设有固定孔172a。
参照图13，电机安装罩110的侧壁外侧的支撑柱与直角固定件172在固定孔172a上通过螺栓固定，而与弹片主体171的下端171b相连的直角固定 件172则与内罩120的底壁121固接。
参照图14，在一实施方式中，内罩120的侧壁向下伸出超出底部121一定距离，形成一个侧壁底部端122，吸尘器壳体200的内部与内罩120的侧壁相对处设有环形的缓冲槽210，缓冲槽210中设有由弹性材料制成的缓冲圈150，内罩120的侧壁底部端122由缓冲圈150所支撑。
再次参照图6，外罩130的裙部131下部设有多个固定耳131a，外罩130通过固定耳131a与吸尘器壳体200的内部相固接。
这里说明的设备数量和处理规模是用来简化本案的说明的。对本案的应用、修改和变化对本领域的技术人员来说是显而易见的。
如上所述，内罩120及外罩130通过密封罩140实现配接及密封，而且密封罩140可由弹性材料制成，使得密封罩140在提供密封的同时，还能够将电机安装罩110传递给内罩120的冲击力进一步缓冲，可以得出结论：电机通过弹性结构170的架空式支撑及密封罩140在其顶部的缓冲式支撑，能够降低电机和整机的震动，同时提高了气流通道的气密性，不仅提高了吸尘器的吸力，而且有效阻隔了噪声，从而实现了整机的减震降噪功能。
尽管本发明的实施方案已公开如上，但其并不仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
