Abstract
A cyclonic separation apparatus for a vacuum cleaner comprising: a cyclone with a longitudinal central axis; a discharge nozzle at a longitudinal end of the cyclone; an air inlet port arranged tangentially through a side of the cyclone; an air outlet port through an opposite longitudinal end of the cyclone; and a dirt container in communication with the cyclone, wherein the dirt container comprises: a base wall penetrated by the discharge nozzle; a top wall spaced apart from the base wall; and a perimeter wall interposing the base wall and the top wall, wherein the dirt container is arranged to convey air flow from the cyclone in an elongate circuit defined by the perimeter wall. A vacuum cleaner comprising: a motor coupled to a fan for generating air flow; and the cyclonic separation apparatus.

A cyclonic separation apparatus for a vacuum cleaner, the cyclonic separation apparatus comprising:
- a cyclone with a longitudinal central axis;
- a discharge nozzle arranged at a longitudinal end of the cyclone;
- an air inlet port through a side of the cyclone, wherein the air inlet port is arranged tangentially to the cyclone;
- an air outlet port through an opposite longitudinal end of the cyclone;
- and
- a dirt container in communication with the cyclone,
- wherein the dirt container comprises:
- a base wall penetrated by the discharge nozzle;
- a top wall spaced apart from the base wall;
- and
- a perimeter wall interposing the base wall and the top wall;
- wherein the dirt container is arranged to convey air flow from the cyclone in an elongate circuit defined by the perimeter wall, wherein the elongate circuit has an axis of elongation with the discharge nozzle located in a portion of the dirt container proximal to an end of the axis of elongation and wherein, in use, air flow passes outbound away from the discharge nozzle in proximity to an initial portion of the perimeter wall and is redirected inside a distal portion of the perimeter wall to turn inbound towards the discharge nozzle adjacent a further portion of the perimeter wall.
