Abstract:
1. A device for the formation of froth in a milk-based drink, comprising: a steam dispensing nozzle; a tubular structure, the steam dispensing nozzle inserted into and removeably connected to the tubular structure so that the tubular structure surrounds the steam dispensing nozzle, the tubular structure comprising an open top, an open bottom, an outer wall and an air inlet hole formed in and extending through the entire thickness of the outer wall; a sleeve disposed around the outer wall of the tubular structure, the sleeve comprising an inner surface that defines an air intake passageway with the outer wall of the tubular structure; and an adjustment element formed on the inner surface of the sleeve, the sleeve being adjustable relative to the tubular structure between a first position in which the adjustment element at least partially overlaps the air inlet hole and a second position in which the adjustment element is staggered from the air inlet hole so that flow of air through the air inlet hole may be adjusted independently from a flow of milk, wherein said tubular structure is formed with a first area inside said tubular structure provided for mixing of milk and air, said first area being distinct from a second area provided for an emulsion of milk, air and steam coming out from said dispensing nozzle, said nozzle has an outlet hole and said tubular structure includes near to the outlet hole of said nozzle, a wall that forms a continuous plane within which is formed a first opening for intake of milk and a second opening for outlet of an emulsion that has formed from milk, air from said air passageway and steam, the second opening is downstream from the outlet hole of the nozzle, and the first opening and the nozzle outlet are positioned at different heights of an axis of the tubular element.
