  • Patent number: 7914596
    Abstract: Behind a front panel of an air purifier are formed guide paths on the right and left sides thereof. A space between the front panel and a filter unit is partitioned by a partition plate into a front panel rear space and a filter unit front space. Part of an airflow that has entered the guide path through an air intake enters the filter unit front space, and the other part thereof enters the front panel rear space. When entering the front panel rear space, the airflow takes a sharp turn at a sharp turn corner. As a result, coarse dust is separated from the airflow, and the separated coarse dust falls into a dust box.

  • Patent number: 7909910
    Abstract: A vacuum clean-out system including a separator chamber and associated collection chamber for removing liquid material and debris from a vacuum output and providing a vacuum return line free of contaminants. A vacuum exhaust line is coupled to a cyclonic separator chamber that induces a circular rotation within the incoming vacuum stream, causing the liquid and debris to impinge the chamber's surfaces and fall to the bottom thereof while the “clean” vacuum is drawn upwards into a return line. The collection chamber is maintained at the same negative pressure as the separator chamber so that the accumulating liquid and debris easily drains into the collection chamber. A sensor associated with the collection chamber may be used to determine when the collection chamber is full and needs to be discharged. At that point, the separator chamber is isolated from the collection chamber, the collection chamber is vented and the accumulated material is discharged and/or analyzed.
