Cyclonic separating apparatus

摘要

A separating apparatus includes a separating chamber in which cyclonic separation is able to take place, an inlet to the separating chamber and a shroud that includes a wall having a multiplicity of through-holes forming an outlet from the separating chamber and also includes a lip extending from the wall into the separating chamber, the lip having has a plurality of apertures therethrough. The provision of apertures in the depending lip allows the airflow to be drawn through the apertures while it is still in the separating chamber. This has the effect of capturing some of the dirt and dust which remains entrained within the airflow so that it collects on the upstream side of the lip. Thus the shroud through-holes are presented with less entrained dirt and dust and the risk of the through-holes becoming blocked is reduced.
