Abstract: A non-contact suction cup device (100) with flow recycling. The device is based on the recycling flow of fluid through one or more passage(s) (12) provided inside a suction cup chamber (51). The device further optionally includes a flow diverter (4) configured to divert the flow of fluid, and suction means (5) either directly or indirectly attached with the suction cup of the device (100), configured to suck or draw the fluid (11) from the periphery (52). The said passage (12) allow part of fluid to recirculate within the device chamber, hence causing a recycling effect on fluid used to create suction, which provides lower acoustic noise and higher energy efficiency.

Abstract: The present invention discloses a high flow low pressure suction device. The device is a non-contact suction device based on multiple stage turbulence based low pressure suction mechanism which comprises fan(s) or rotating impeller(s) for drawing air/fluid/slurries operates without any seal between the device and the sucked surface. The device compounds this turbulence based low pressure generation along with Bernoulli's principle to yield a high efficiency suction device. The device implements the above concept by making the air/fluid/slurries flow through two or three zones selected from the acceleration zone(s), turbulence zone(s) (high turbulence zone) and smooth zone(s) (minimum turbulence zone).
