Description

用于真空吸尘器的旋风收尘装置的格栅组件
技术领域
本发明涉及一种真空吸尘器的旋风收尘装置，尤其涉及一种用于防止灰尘流入真空发生装置的真空吸尘器的旋风收尘装置的格栅组件。
背景技术
图1示出了传统的用于真空吸尘器的旋风收尘装置。如图1所示，传统的用于真空吸尘器的旋风收尘装置10包括旋风体20和收尘部分30。
在旋风体20的上部设置有与真空吸尘器刷格栅组件(未示出)相连的空气吸入通道21，从该空气吸入通道21吸入的空气沿旋风体20的切线方向流动，并形成涡旋气流。
在旋风体20的上部中心部位设置有与真空吸尘器的真空发生装置(未示出)相连接的空气排出通道22，为了防止灰尘流入真空发生装置，在空气排出通道22的入口处设置格栅体23。
该格栅体23具有多个形成在其上的通道24，当真空吸尘器的真空发生装置工作时，存在于洁净表面上包含各种灰尘的空气通过上述刷格栅组件和空气吸入通道21被吸到旋风体20中。
吸入到旋风体20中的空气形成涡旋气流，而包含在空气中的灰尘通过离心力而被分离并被收集在收尘部分30中。此后，空气通过格栅体23上的通道24和空气排出通道22流到真空发生装置中。
同时，没有从空气中分离出来的部分灰尘通过格栅体23上的通道24穿过格栅体23，并通过空气排出通道22流到真空发生装置中，因此降低了真空吸尘器的吸尘功能。
发明内容
本发明的目的是提供一种用于真空吸尘器的旋风收尘装置的格栅组件，其通过在灰尘穿过格栅体后防止灰尘流入真空发生装置而能够改善真空吸尘器的吸尘功能。
本发明的另一个目的是提供一种用于真空吸尘器的旋风收尘装置的格栅组件，其通过容易地安装和拆卸格栅体使格栅体能以轻松的方式清洁。
上述目的是通过提供一种用于真空吸尘器的旋风收尘装置的格栅组件，该格栅组件设置在旋风体的空气排出通道的上部用于通过将吸入的空气形成涡旋气流并通过离心力而将灰尘从涡旋气流中分离出来，所述格栅组件用于防止灰尘流入到真空吸尘器的真空发生装置中，该格栅组件包括：格栅体，该格栅体具有多个形成在其上的通道并具有两端开口的圆筒形状；密封件，该密封件用于密封格栅体的一个开口；固定装置，该固定装置包括与密封件的上部形成一体的锁定旋钮和设置在格栅体的相应部分上的通孔，该通孔允许锁定旋钮在预定位置从其中穿过，其中在格栅体的通孔周围设置有凸部，由于所述锁定旋钮在凸部上的相关联的运动，密封件被牢固地安装在格栅体中。该固定装置用于容易地将密封件固定在格栅体中，即用于容易地将密封件固定在格栅体中和将其从格栅体中拆卸下来。
附图说明
图1是传统真空吸尘器的收尘装置的剖视图；
图2是根据本发明的真空吸尘器的收尘装置的格栅组件的拆分透视图；
图3是图2所示格栅组件的锁定旋钮连接部分的透视图；
图4是图2所示格栅组件安装到旋风收尘装置上的剖视图。
具体实施方式
下面，将结合附图对本发明的优选实施例进行详细说明。
图2中示出了根据本发明用于真空吸尘器的旋风收尘装置的格栅组件。用于真空吸尘器的旋风收尘装置的格栅组件100包括格栅体110、密封件120和过滤装置130。
格栅体110具有多个形成在其上的通道111。格栅体110具有两端开口的圆筒形状，其上开口端与空气排出通道22相连，而其下开口端由密封件120进行密封。
在密封件120的外圆周上设置有灰尘回流阻止单元121，灰尘回流阻止单元121将朝着格栅体110的气流中所含的灰尘的方向转换为朝着旋风收尘装置10中的涡旋气流。
过滤装置130包含过滤器支撑部分131和由该过滤器支撑部分131支撑的过滤网132，过滤器支撑部分131与密封件120形成一体，并且过滤网132固定在过滤器支撑部分131上。
同时，密封件120具有设置在其上部的锁定旋钮140，该锁定旋钮与密封件120形成一体。如图3所示，锁定旋钮140从密封件120的上表面到预定高度具有圆筒形状，而圆筒形状的上部则具有手柄形状。
在格栅体110的下部设置有锁定旋钮连接部分150以与密封件120上锁定旋钮140相对应。如图3所示，该锁定旋钮连接部分150具有设置在其上用于容纳所述锁定旋钮140的通孔151，以及设置在该通孔151周围的凸部152。
凸部152是这样形成的，即锁定位置比非锁定位置高0.5mm。因此，由于锁定旋钮140在凸部152上相关联的运动，该密封件120牢固地安装在所述格栅体110中。
换而言之，如果密封件120上的锁定旋钮140在穿过格栅体110上的通孔151后旋转90°，那么密封件120就牢固地固定格栅体110中。因此，不用任何特殊的工具就可以将密封件120固定在格栅体110中并从格栅体110中将其拆卸下来。此外，由于锁定旋钮140和锁定旋钮连接部分150设置在过滤装置130中，因此不会发生灰尘流入到它们的连接部分中从而引起安装和拆卸密封件120中的问题。
同时，格栅组件100的维护和修理或过滤网的清洁都变得很方便。图3中未指定的标号153和154分别表示从格栅体110突出的限位块，其目的是为了控制锁定旋钮140的锁定位置和非锁定位置。
图4中示出了安装于旋风体20中具有上述结构的格栅组件100。格栅组件100通过诸如螺栓的连接件(未示出)可拆卸地安装于旋风体20中。
同时，当真空吸尘器的真空发生装置工作时，在旋风体20内部将形成涡旋气流。包含在涡旋气流中的各种灰尘通过离心力被从所述气流中分离出来，并且分离出来的灰尘被收集在收尘部分30中。
在上述收尘步骤中没有通过离心力从气流中分离出来的部分灰尘则由于上升的气流而沿着旋风体20的中心旋转并向格栅组件100方向移动。
此时，气流中的部分灰尘在它们与密封件120上的灰尘回流阻止单元121碰撞后被反射并被转换成朝向涡旋气流。因此灰尘再次旋转到涡旋气流中。
通过灰尘回流阻止单元121没有从上升气流中分离出来的残留灰尘流到格栅组件100的通道111中。由于格栅组件100内部和外部之间的压差，空气通过通道111流入格栅组件100内。
包含在气流中的灰尘由过滤网132过滤，因此只有清洁的空气流到真空发生装置中。从而避免了由于灰尘被吸到真空发生装置中造成的真空吸尘器吸尘功能的降低。
此外，为了清洁格栅组件100和更换新的过滤网132，密封件120以这样的方式从格栅体110上拆卸下来，即将密封件120沿预定方向旋转90°，然后将其拉出。在清洁和更换之后，密封件120以这样的方式牢固地安装在格栅体110上，即将密封件120的锁定旋钮140穿过格栅体110上的通孔151，然后沿相反方向旋转90°。
根据本发明用于真空吸尘器的旋风收尘装置的格栅组件100，灰尘不可能通过旋风体20的排出通道22沿气流被吸入到真空吸尘器的真空发生装置中，因此可以改善真空吸尘器的吸尘功能。
此外，根据用于真空吸尘器的旋风收尘装置的格栅组件100，由于密封件120的安装和拆卸都很方便，因此清洁格栅体也很容易。
至此，已经说明了本发明的优选实施例，然而，本发明不仅限于这里所描述的优选实施例，本领域的技术人员在不歪曲本发明精神的前提下可以对本发明进行修改。
