下面将描述本发明其它的特征和优点，并且通过下面的附图和细节描述，将变得显而易见。
附图说明
附图根据其中原理的实际应用图解了本发明的优选实施例，其中：
图1图解了根据本发明的包括该除尘器组件的滑动式断锯；
图2图解了本发明的该除尘组件；和
图3沿着图1中的III-III线展示了轨道端盖。
具体实施方式
参照图1，其展示了根据本发明的带有除尘器组件20的断锯10。本领域的技术人员应该认识到，图1图解了滑动式斜切锯(miter saw)，但是他们还应认识到，本发明可以在任何其它类型的断锯和/或动力工具中实施。
滑动斜切锯10包括转动地设置在基座12上的工作台11。工作台11可以具有栅栏13。另外，支臂外壳14可以转动地连接到工作台11上。支臂外壳14可以滑动地容放至少一个滑动轨道15，滑动轨道15又连接到锯组件16上。该锯组件优选地包括上锯片防护板18、连接到该上锯片防护板18上的马达16M和由该马达驱动的锯片17。上锯片防护板18可以包括后防护板18R，其部分地覆盖在锯片17的后部。优选地，锯组件16绕枢轴P转动，允许用户在上位和下位之间移动该锯组件16，以切断设置在基座12和/或工作台11上的工件(workpiece)。
参照图1-2，斜切锯10也可以包括除尘组件20。这种除尘组件20揭示在美国专利第6,742,425号中，其在此按引用合并。除尘组件20可以包括用于连接该除尘组件20到上锯片防护板18上的柱22。柱22可以具有用于增加该柱22强度的筋(rib)22R。柱22优选连接到灰尘输送管21上。
优选地，灰尘输送管21由ABS或XENOY塑料，或任何其它合适的材料制造。灰尘输送管21可以具有用于容放由该切断操作产生的灰尘的入口21I和排放该灰尘的出口21O。
优选地，入口21I的横截面基本上为向下的U-型开口。另一方面，该出口21O的该横截面可以基本上为圆形且密闭。优选地，出口21O的直径约为35毫米。本领域的技术人员应该认识到，入口21I的宽度优选比该出口21O的该宽度窄。
灰尘垂下物(dust flap)23可以设置在灰尘输送管21的下面。灰尘垂下物23可以由弹性橡胶布，如涂有聚氯丁烯的尼龙制造。优选地，该灰尘垂下物由Reevecote 18403制造。
灰尘垂下物23可以设置在该入口21I的开口部分中，这导致基本上闭合的横截面21IA。横截面21IA的宽度和高度可以分别约为14毫米和150毫米。
该横截面21IA的面积可以至少为出口21O的截面积的约1.5倍。优选地，横截面21IA的面积约为出口21O的截面积的1.5至2倍。优选地，该横截面21IA的面积约为1568平方毫米，而出口21O的截面积约为960.2平方毫米。
本领域的技术人员将认识到，从该灰尘输送管21延伸的该折叠的灰尘垂下物23的形状基本上为三角形。
本领域的技术人员应该认识到，提供弹性材料的灰尘垂下物23，如橡胶布，使得当移动通过栅栏13时，允许该灰尘垂下物23沿工件滑动或折叠，然后基本上回到起始形式。
灰尘输送管21也可以具有用于保持该灰尘垂下物23打开的金属丝21W。如图2所示，优选地，该金属丝21W绕灰尘输送管21向下延伸，延伸通过灰尘垂下物23，然后绕灰尘输送管21内侧钩住。金属丝21W可以延伸通过灰尘垂下物23上的孔或槽23S。另外，金属丝21W可以通过吊钩部分21WH绕灰尘输送管21的内侧钩住。
本领域的技术人员将认识到，该金属丝21W可以形成为增加横截面21IA宽度的形状。因此，横截面21IA的面积可以至少为出口21O的截面积的1.5倍(并且优选约为3倍)。
本领域的技术人员将认识到，如果转动地连接到强真空源上的真空软管连接到该出口21O上，该灰尘垂下物23自身可以关闭或闭合。然而，该金属丝21W可以保持灰尘垂下物23打开，以便正常除尘。
管24可以连接到出口21O上。管24可以延伸通过臂壳体14。优选地，臂壳体14具有通道25。管24可以延伸通过通道25。通道25优选由设置在外壳14内的套25P形成。套25P可以由塑料制造。本领域的技术人员应该认识到，除尘袋和/或软管26(其可以连接到真空源上)可以连接到该套25P上。
优选地，管24嵌入套25P中。由于该软管26不直接连接到出口21O上，因此这样设置将会提供相对静止的软管26。
本领域的技术人员应该认识到，如果软管26没有连接到套25P上，管24和/或套25P可以形成为增加进入管24的空气速度的形状，从而产生文丘里效应并且移动该灰尘到除尘袋中。
参照图1至3，该锯10可以具有两个或多个轨道15。优选在该轨道15上提供接头15C，以便保持它们之间的距离相对一致。接头15C优选具有围绕轨道15的法兰15F。螺钉15S可以延伸通过法兰15F，并且螺纹地啮合接头15C以夹紧轨道15。本领域的技术人员将会认识到，接头15C优选具有足够的法兰15F来围绕每个轨道15。
本领域的技术人员将认识到，接头15C可以设置在轨道15的末端上，或沿轨道15的任何位置上。
本领域的技术人员可以认识到在此揭示的方法的其它替代方法，然而，所有这些添加和/或变更都认为是本发明的等同物。
