Abstract
The invention provides dust separating apparatus (10) including a cyclone (14) having an outer wall (14a) and an air inlet (12), a shroud (16) and an airflow path, the airflow path being arranged so as to direct an airflow flowing, in use, in the dust separating apparatus into the cyclone (14) via the air inlet (12) and out of the cyclone through the shroud (16). The air inlet (12) of the cyclone (14) is formed by a conduit (12a) projecting into the cyclone (14) between the outer wall (14a) and the shroud (16). This allows a swivel coupling to be attached to the air inlet (12) providing greater flexibility and maneuverability of the dust separating apparatus (10).
Claims11
Dust separating apparatus comprising a cyclone having an outer wall and an air inlet into the cyclone, a shroud for an air outlet spaced apart from the outer wall of the cyclone and an airflow path, the airflow path being arranged so as to direct an airflow flowing, in use, in the dust separating apparatus into the cyclone via the air inlet and out of the cyclone through the shroud, wherein the air inlet of the cyclone is formed by a conduit projecting into an interior of the cyclone between the outer wall thereof and the shroud in a direction substantially parallel to a longitudinal axis of the cyclone.
A vacuum cleaner having a dust separating apparatus which comprises, a first cyclone having an outer wall and an air inlet into the first cyclone, a shroud for an air outlet spaced apart from the outer wall of the first cyclone, a first airflow path being arranged so as to direct an airflow flowing, in use, in the dust separating apparatus into the first cyclone via the air inlet and out of the first cyclone through the shroud, and a second cyclone arranged downstream of the shroud, wherein the air inlet of the first cyclone includes a conduit projecting into an interior of the first cyclone between the outer wall and the shroud in a direction substantially parallel to a longitudinal axis of the first cyclone and a right angle bend mounted on an end of the conduit in the interior of the first cyclone for causing airflow to flow, in use, in a tangential manner in the first cyclone and wherein a swivel coupling is provided on an end of the conduit opposite the right angle bend adjacent a second airflow path immediately upstream of the conduit.
