Abstract
一种真空吸尘器旋风集尘装置包括一个中空圆筒形旋风体,其具有一个敞开上端和一个排尘口。一个尘土容器连接着旋风体。一个底座件连接并封闭了旋风体和尘土容器的下端,一个盖子连接着旋风体和尘土容器的上端。盖子包括一个进气通路和一个排气通路。装置还包括一个防逆流装置,用以引导杂质从旋风体排入尘土容器中并防止尘土容器中收集的杂质逆流返回旋风体中。
Description
本发明涉及一种真空吸尘器,具体地讲是涉及一种用在真空吸尘器中的旋风集尘装置,其用于离心分离并收集所吸入空气中夹带的杂质。
一般来说,真空吸尘器包括一个活动连接着吸尘器本体的吸气刷,该吸气刷在清洁过程中将沿着清洁表面移动。吸尘器本体具有一个内部装有可拆卸尘土过滤器的集尘室和一个装有吸力产生电机的电机工作室。当电机工作时,它会在吸气刷处产生强大吸力。这样,清洁表面上的尘土或污物等杂质会随着空气一起被吸入吸尘器本体内。夹杂在空气中的杂质通过安置在吸尘器本体的集尘室中的尘土过滤器而被过滤掉,而清洁空气通过电机工作室而排放回周围环境中。
传统真空吸尘器利用可耗式尘土过滤器收集杂质。当尘土过滤器中充满了杂质时,必须手工更换尘土过滤器。手工更换尘土过滤器是很不便的事,而且会导致恶劣的卫生状况。
本发明的研制是为了克服相关技术中的上述问题,因此本发明的目的是提供一种用在真空吸尘器中的旋风集尘装置,其用于离心分离和收集由吸气刷吸入真空吸尘器的空气中夹带的杂质。
上述目的可以通过提供这样一种真空吸尘器旋风集尘装置而实现,该装置包括一个上端和下端都敞开的中空圆筒形旋风体和一个位于旋风体下端附近的排尘口,排尘口用于接收通过离心力从空气中分离出来并从旋风体内排出的杂质。装置还包括一个连接着旋风体的尘土容器。尘土容器收集由排尘口排出旋风体的杂质。一个底座件连接并封闭了旋风体和尘土容器的下端,一个盖子以可取下的方式连接着旋风体和尘土容器的上端。盖子包括一个用于将外部空气和杂质吸入旋风体的进气通路和一个用于将旋风体中的干净空气排出的排气通路。装置还包括一个防逆流装置,用以引导杂质从旋风体排入尘土容器中并防止尘土容器中收集的杂质逆流返回旋风体中。
按照本发明的真空吸尘器旋风集尘装置包括一个导向件,其邻近于形成在旋风体中的排尘口。导向件可以有效地引导杂质由排尘口进入尘土容器中并防止杂质逆流回到旋风体。这样,本发明的旋风集尘装置可以提高真空吸尘器的效率和性能。
以下结合附图进行详细说明,从而本发明的上述目的和其它特点更加清楚,附图包括:
图1是带有根据本发明优选实施例的旋风集尘装置的真空吸尘器的示意性透视图;
图2是图1中的旋风集尘装置的示意性透视图;
图3是图2中旋风集尘装置的旋风体和尘土容器的俯视图。
下面将结合附图而以实例的形式更详细地描述本发明的旋风集尘装置。
图1是带有根据本发明优选实施例的旋风集尘装置的真空吸尘器的透视图。
请参考图1,真空吸尘器包括一个吸尘器本体1、一个可活动地连接着吸尘器本体1的吸气刷3和一个旋风集尘装置5。
吸尘器本体1具有一个用于放置旋风集尘装置5的集尘室1a和一个用于安装电机的电机工作室(未示出)。电机工作室安置在集尘室1a下方并通过一个排气管4与集尘室1a连通。电机(未示出)产生强大吸力,以使吸气刷3能够抽吸清洁表面上的杂质。吸气刷3通过一个吸气管2连接着集尘室1a中的集尘装置5。
旋风集尘装置5离心分离并收集由吸气刷3吸入的空气中夹带的杂质。旋风集尘装置5以可拆卸的方式放置在集尘室1a中。如图2和3所示,旋风集尘装置5包括一个旋风体11、一个尘土容器13、一个底座件15、一个盖子17和一个防逆流装置。
旋风体11是一个上下端都敞开的中空圆筒。旋风体11具有预定的内径并带有一个预定尺寸的排尘口11a。从吸气刷3吸入的空气和杂质将进入旋风体的上端,在此处形成为旋风并通过离心力而分离。杂质将从排尘口11a中排出。排尘口11a的轮廓线11b和11c的曲率半径不同于旋风体11的曲率半径。延伸到尘土容器13的平缓轮廓线11b的曲率半径大于旋风体11的曲率半径,以便有效地引导杂质移向尘土容器13。弯曲轮廓线11c的曲率半径小于旋风体11的曲率半径,以便扩大出口,从而可以有效地引导尽可能多的杂质经过排尘口11a。
由排尘口11a从旋风体11排出的杂质被收集和存放在位于旋风体11附近的尘土容器13中。尘土容器13环绕着旋风体11的一部分。具体地讲,中空筒形尘土容器13优选与旋风体11形成为一体而且高度与旋风体11相等。旋风体11和尘土容器13通过排尘口11a而彼此连通。尘土容器13由旋风体11中的延伸平缓轮廓线11b成形而来。
旋风集尘装置5的底座件15连接并封闭了旋风体11和尘土容器13的下端。底座件15优选与旋风体11和尘土容器13形成为一体。
盖子17以可取下的方式连接并覆盖着旋风体11和尘土容器13的上端。盖子17包括一个进气通路17a和一个排气通路17b,二者均与旋风体11连通。进气通路17a连接着用于从吸气刷3中吸入空气和杂质的吸气管2。进气通路17a向着旋风体11上端中心延伸但从该中心偏移开,如图2所示,以便将吸入旋风体11的空气引导成为旋风。排气通路17b从盖子17的中心附近延伸到盖子一侧。排气通路17b连接着排气管4并与电机工作室连通。排气通路17b将与杂质离心分离的清洁空气排放回周围环境中。
集尘装置5的防逆流装置将保留从旋风体11排放到尘土容器13中的杂质并防止所收集的杂质返回旋风体11。防逆流装置包括一个从排尘口11a的一条轮廓线伸向尘土容器13内部的导向件19。如图3所示,导向件19相对于旋风体11的外周边呈锐角安置。此外,导向件19毗邻位于旋流下游区域的弯曲轮廓线11c安置。导向件19从盖子17延伸到底座件15,以便沿着尘土容器13的全长防止逆流。此外,导向件19优选由诸如薄膜等弹性材料制成,以便在受到来自排尘口11a的排气压力时能够柔性弯曲。导向件19通过诸如粘胶等粘结剂在排尘口11a附近附着在旋风体11外侧。导向件19具有与旋风体11外周边一致的曲率半径。这样,导向件19的曲率半径可以确保有效地引导杂质从排尘口11a排放到尘土容器13中,并且可以通过防止导向件的反向变形而防止所收集的杂质逆流到旋风体11中。
旋风集尘装置5还包括一个形成在旋风体11外表面上的手柄12,如图2所示。
下面将描述本发明的旋风集尘装置的操作。
当真空吸尘器工作时,强大吸力会产生在吸气刷3处。清洁表面上的杂质会随着空气而被吸入吸气刷3中,并且经过吸气管2和进气通路17a而进入旋风体11中。吸入的空气被进气通路17a沿对角方向引入旋风体11中并变成旋流,如图3中的箭头所示。杂质将沿着旋风体11内侧下降。旋流的离心力会将杂质从空气中分离出来,而且杂质会经过排尘口11a而喷射到尘土容器13中。当杂质被收集到尘土容器13中后,它们将在导向件19后面堆放起来。由于排气压力的作用,尘土容器13中收集的杂质会在尘土容器13中以紊流的形式移动,但是导向件19可以阻塞路径,以防止杂质由排尘口11a返回旋风体11。
与杂质分离后的清洁空气将经过排气通路17b、排气管4、吸尘器本体1的电机工作室以及出口(未示出)而排放到周围环境中。
当尘土容器13被充满后,旋风集尘装置5可以从吸尘器本体1的集尘室1a中取出。之后,旋风集尘装置5的盖子17可以从旋风体11和尘土容器13上拆下,从而尘土容器13中收集的杂质可以倒出。
上述本发明的优选实施例被用于直立式真空吸尘器中。然而,旋风集尘装置5也可以被实施到图中未示出的罐式真空吸尘器。
如上面详细描述,真空吸尘器旋风集尘装置包括一个导向件,其邻近于形成在旋风体中的排尘口。导向件可以有效地引导杂质由排尘口进入尘土容器中并防止杂质逆流回到旋风体。这样,本发明的旋风集尘装置可以提高真空吸尘器的效率和性能。
