Portable devices for touchless particulate matter removal
First Claim
1. A portable device for dislodging particulate matter from a surface, the portable device comprising:
- a body segment that is movable with respect to a surface from which particulate matter is being dislodged;
a high-pressure assembly operably connected to the body segment and generating a high-pressure fluid flow for being emitted toward the surface from which the particulate matter is being dislodged; and
a nozzle assembly operatively connected to and receiving the fluid flow from the high-pressure airflow assembly, the nozzle assembly including multiple nozzles that are spaced from each other and configured to emit the fluid flow as a series of discrete pulses such that each of the multiple nozzles defines a blast diameter upon the surface from which the particulate matter is being dislodged, andwherein a cumulative blast pattern is defined by the combined blast diameters of the multiple nozzles, the cumulative blast pattern defining a coverage area that corresponds in size to an area value of a downwardly facing area of the nozzle assembly.

Abstract
Portable devices for dislodging and/or capturing particulate matter that has accumulated on various surfaces or structures are provided. The devices include a body segment and a nose segment extending away therefrom. A high-pressure assembly generates a high-pressure airflow that is directed to a nozzle assembly in the nose segment. From the nozzle assembly, the high-pressure airflow can be emitted from multiple nozzles as a series of airflow bursts that discretely contact the surface from which the particulate matter is being dislodged. The configuration of each nozzle, as well as the overall arrangement and positions of all the nozzles together, is selected to impart the desired particulate matter dislodging characteristics to the device, and the device may incorporate a vacuum airflow to remove the particulate matter after such matter has been dislodged.
