摘要： A manual machine tool (10) includes a vacuum device for dust removal (19) situated in its housing (12) and a blow-out connection (20) installed after this. A dust collection box (21), particulaily self-contained, can be attached in detachable fashion to the blow-out connection (20) via its blow-in connection (22). The dust collection box (21) is airtight on all but two sides and has air-exit holes (40) on the top side (36) and a dustproof filter element (48)—especially a fluted filter—on the inside. The dust collection box is particularly secure against the unintentional escape of dust after the dust collection box is detached from the associated manual machine tool because a pair of sealing lips (500) arranged as a separate part is provided inside the blow-in connection (22), which pair of sealing lips (500) is connected as a single part with closing flaps (520, 520) projecting into the interior of the dust collection box (210).
摘要翻译：手动机床（10）包括位于其壳体（12）中的用于除尘（19）的真空装置和在此之后安装的吹出连接（20）。特别独立的灰尘收集箱（21）可以通过其吹入连接（22）以可拆卸的方式附接到吹出连接（20）。集尘盒（21）除了两面都是气密的，并且在内侧具有顶侧（36）上的排气孔（40）和防尘过滤元件（48），特别是槽形过滤器。灰尘收集箱特别牢固，防止灰尘收集箱从相关联的手动机床上拆下后灰尘的无意逃逸，因为在吹入连接（22）内设置一对作为分离部件布置的密封唇（500）），所述一对密封唇（500）作为单个部分连接，其中突出到所述集尘盒（210）的内部的封闭翼片（520,520）。
