Abstract
The invention relates to a spray unit comprising an axle (20), a disc (30), a disc shape modifying assembly (40) and a liquid applicator (50). The disc is configured to spin about the axle centred on the centre of the disc. The liquid applicator is configured to apply liquid to a surface of the disc. The disc shape modifying assembly is configured to modify the trajectory of the liquid droplets that leave the spray unit by way of varying the diameter of the disc.
Claims16
A spray unit, comprising:
- an axle;
- a disc;
- a disc shape modifying assembly;
- and
- a liquid applicator;
- wherein, the disc is configured to spin about the axle centered on the center of the disc;
- wherein, the liquid applicator is configured to apply liquid to a surface of the disc;
- wherein the disc shape modifying assembly is configured to modify a trajectory of liquid droplets that leave the spray unit by way of varying a diameter of the disc while the disc spins about the axle centered on the center of the disc.
5 more elements
A spray unit, comprising:
- an axle;
- a disc;
- a disc shape modifying assembly, including:
- at least one movable geometry defining component configured to vary a diameter of the disc or a second disc by way of change of at least a part of the geometry defining component's position;
- and
- at least one actuator configured to move the at least one geometry defining component;
- and
- a liquid applicator;
- wherein the disc is configured to spin about the axle centered on the center of the disc;
