| 161 | Cyclonic Separator | US14013936 | 2013-08-29 | US20140059800A1 | 2014-03-06 | Alexander Anthony Denny Bassett |
| A vacuum cleaner comprises first and second devices 116,125 for separating dirt and dust from an airflow through the cleaner. The dirt and dust separated by the first and second devices 116,125 is deposited at the bottom of a collection chamber 112. The dirt and dust separated by the second device 125 is transferred to the bottom of the collection chamber 112 via a duct which is normally closed by a valve 124 to prevent air from leaving the chamber 112 along the duct 133 instead of forming a proper cyclonic flow in the chamber 112. An actuator 131, 135, 136 is provided for periodically opening the valve 124 to release the collected dirt and dust into the bottom of the chamber 112. The actuator 131, 135, 136 simultaneously closes the duct 133 between the valve 124 and the second device 125, so as to temporarily prevent air from leaving the chamber 112 along the duct 133 whilst the collected dirt and dust is released. In this manner the dirt and dust from both devices can be collected together and compacted by a single compaction auger 120. | ||||||

| Handheld portable devices for dislodging and capturing particulate matter that has accumulated on various surfaces or structures are provided. The devices create opposing airflows that can intimately interface with each other during use. A vacuum airflow is drawn into the device, defining a vacuum affected zone upon the surface being cleaned. A high pressure airflow is emitted that penetrates through or passes adjacent to the opposing vacuum airflow and contacts the surface being cleaned, dislodging particulate matter therefrom. The high pressure airflow can be emitted from multiple nozzles as a series of airflow bursts that discretely contact the surface being cleaned. The configuration of each nozzle, as well as the overall arrangement and positions of all the nozzles together, are selected to impart the desired particulate matter dislodging characteristics to the device. | ||||||
