Vortex-flow vacuum suction nozzle

摘要

A vacuum suction nozzle comprises a nozzle body comprising a first end and a second end, a nozzle passage extending through the nozzle body from the first end to the second end, and a plurality of channels traversing the first end. The channels enter the nozzle passage tangentially. Each channel may be wider proximate an outer surface of the nozzle body than proximate the nozzle passage. A vacuum system comprises the nozzle and a vacuum generator coupled to the nozzle. A method for vacuum cleaning comprises inducing a vortex flow proximate the nozzle with a vacuum generator, and translating the nozzle generally parallel to a surface to remove particulates from the surface.

1. A vacuum suction nozzle comprising:
a nozzle body having a first end and a second end; a nozzle passage extending through the nozzle body from the first end to the second end; and a plurality of channels each traversing the first end of the nozzle body and each intersecting the nozzle passage tangentially, wherein each channel is defined by opposing channel walls that are separated widest proximate an outer surface of the nozzle body and separated narrowest proximate the nozzle passage.
