    • A portable power tool such as a portable circular saw is provided with a sawdust collection system based on the generation of an air flow resulting from rotation of a rotary cutting blade, with this air flow being guided to transport sawdust resulting from cutting operations along a guide path through a first discharge aperture into a dust box in which the sawdust is precipitated, with a low-velocity air flow then passing out of the dust box through a second discharge aperture to be recirculated through the flow path. Extremely effective dust collection is attained with a simple configuration, while the dust box can be positioned such that the weight of accumulated sawdust therein does not significantly affect the balance or ease of operation of the portable power tool.
    • 便携式电动工具例如便携式圆锯具有锯屑收集系统,该系统基于由旋转切割刀片的旋转产生的空气流的产生,该空气流被引导以沿着导向件的切割操作运送锯屑 通过第一放电孔进入到其中沉淀有锯屑的灰尘盒中的低速气流,然后通过第二排放孔从集尘箱中通过,以通过流路再循环。 以简单的结构实现了非常有效的集尘,而集尘箱可以定位成使得其中累积的锯屑的重量不会显着影响便携式电动工具的平衡或易于操作。

    • A portable circular saw has a main body (8) accommodating a motor therein, a sawing blade (4) rotated by the motor, a dust casing (3) covering the upper part of sawing blade (4), and a base (9) mounting main body (8). A plurality of partition plates (12a-12e) and a step-up portion (13) are arranged in a hollow space of dust casing (3). These plates (12a) to (12e) and step-up portion (13) have a surface perpendicular to a plane of sawing blade (4). A side wall (17) of dust casing (3) is recessed inward. Base (9) is an aluminum casting product. A link portion (11), provided on base (9), is rotatable about a pivot (18) so as to allow an angular adjustment between base (9) and sawing blade (4).
    • 便携式圆锯具有容纳电机的主体(8),由马达旋转的锯刀(4),覆盖锯刀(4)的上部的防尘壳(3)和基座(9) 安装主体(8)。 多个分隔板(12a-12e)和升压部(13)设置在防尘壳(3)的中空空间中。 这些板(12a)至(12e)和升压部(13)具有垂直于锯切刀片(4)的平面的表面。 灰尘壳体(3)的侧壁(17)向内凹入。 底座(9)是铝铸造产品。 设置在基座(9)上的连杆部分(11)能够围绕枢轴(18)旋转,以便在基座(9)和锯切刀片(4)之间进行角度调节。
