Cyclonic Vacuum Cleaner

Abstract

A cyclonic vacuum cleaner includes a body portion, a nozzle portion and a dirt cup which is removable from the body portion. The dirt cup collects dirt and other debris separated by a cyclone and a cyclone slinger portion in the body portion. A main filter may be housed in a transparent filter door downstream of the cyclone. The dirt cup may be inserted into and sealingly held within the body portion by using a rotational caroming structure.

1 . A vacuum cleaner comprising:
 a body portion;   a nozzle portion having a nozzle opening with a first conduit leading from the nozzle opening to the body portion;   a cyclone having a cyclone inlet, a cyclone outlet, and a cyclone slinger, wherein the first conduit leads to the cyclone inlet and the cyclone is configured to contain a swirling airflow traveling from the cyclone inlet-through the cyclone slinger and out the cyclone outlet, and the cyclone slinger comprises
 a bottom platform, 
 a peripheral wall extending upwardly from the bottom platform and having one or more side ports, and 
 a slinger passage leading away from at least one of the one or more side ports of the peripheral wall, the slinger passage leading to a bottom port opening substantially downwardly; and 
   a dirt cup removably retained within the body portion underneath the cyclone slinger for retaining dirt or other debris exiting from the cyclone slinger through the bottom port; and   a suction source disposed in the body portion or the nozzle portion for generating the airflow within the vacuum cleaner, wherein a second conduit leads from the cyclone outlet to an inlet of the suction source.
