Patent ID: 8864050

Claim:
A jet-breaker device for a jet irrigation apparatus ( 2 ) having a launch pipe ( 2 ) disposed along an extension axis (X) and provided at one end ( 5 ) of a nozzle ( 6 ) for supplying an irrigation liquid let, the device comprising: a support frame ( 7 ) having an anchoring portion ( 8 ) for attachment to the launch pipe ( 3 ) of the let irrigation apparatus ( 2 ); and a jet-breaker ( 9 ) connected to said support frame ( 7 ) and configured to at least partially project with respect to the nozzle ( 6 ) of the jet irrigation apparatus ( 2 ) for interfering with an outlet jet, wherein said jet-breaker ( 9 ) comprises at least one jet-breaking element ( 10 ) configured to oscillate with a predetermined frequency on a plane (π) substantially parallel to said extension axis (X) between a position substantially aligned with the nozzle ( 6 ), such to interfere with the irrigation liquid jet and cause a partial breaking thereof, and a position misaligned with the nozzle ( 6 ), such to not interfere with the irrigation liquid jet, and wherein said jet-breaker ( 9 ) is motorized such to controllably adjust oscillation of said at least one jet-breaking element ( 10 ) and modify an oscillation frequency thereof, further comprising a motor ( 11 ) operatively coupled to said support frame ( 7 ) to act on said jet-breaker ( 9 ), promoting oscillation thereof, adjusting the oscillation of said at least one jet-breaking element ( 10 ), and modifying an oscillation frequency thereof, wherein said support frame ( 7 ) comprises a first supporting portion ( 12 ) of said motor ( 11 ) and a second supporting portion ( 13 ) of said let-breaker ( 9 ), said first ( 12 ) and said second supporting portion ( 13 ) being both configured to be anchored to the launch pipe ( 3 ) of the let irrigation apparatus ( 2 ) on which said first ( 12 ) and said second supporting portion ( 13 ) are installed, wherein said let-breaker ( 9 ) comprises a plurality of interference elements ( 10 , 10 ′, 10 ″, 10 ′″) having different configurations and mounted on said second supporting portion ( 13 ), said interference elements ( 10 , 10 ′, 10 ″, 10 ′″) being selectively locatable in front of an outlet opening of the nozzle ( 6 ) for oscillating between said substantially aligned position and said misaligned position, wherein said second supporting portion ( 13 ) comprises a plate ( 15 ) rotatably mounted onto said anchoring portion ( 8 ) and configured to rotate about a rotation axis (W) substantially orthogonal to said plane (π), and wherein said anchoring portion ( 8 ) is substantially tubular, has a longitudinal axis (L), and is configured to be mounted onto the launch pipe ( 3 ) coaxially therewith, said rotation axis (W) of said plate ( 15 ) being substantially orthogonal to said longitudinal axis (L).
