The invention relates to a spray unit (10) with an axle (20), an atomising disc (30), a spray direction modifying assembly (40), and a liquid applicator (50). The atomising 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 atomising disc. The spray direction modifying assembly is in proximity to the atomising disc. The spray direction modifying assembly comprises at least one air channel (41). The at least one air channel is configured to provide air in proximity to the atomising disc to modify the subsequent trajectory of the liquid droplets that leave the outer edge of the atomising disc.

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.

The invention relates to a spray unit comprising an axle (10), a disc (20), a liquid applicator (40) and a spray direction assembly (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 spray direction assembly partially surrounds the disc. The inner surface of the spray direction assembly is configured to modify the trajectory of all liquid that leaves the outer edge of the disc.

An electrostatic centrifugal spraying system for direct electrification includes a tank configured to store liquid. The tank includes an internal dielectric surface and an external conducting surface, wherein when the liquid is stored in the tank, the tank is configured to act as a capacitor storing electrical energy for electrostatic spraying. The spraying system further includes a power supply, configured to electrify liquid drops of the stored liquid, and a spray nozzle, comprising a spray disk for blowing the electrified liquid drops unto a target.

The present invention relates to a disc (10) for a spinning disc liquid atomizer. A surface (20) of the disc comprises a plurality of concentric rings (30) having different radii centred on the centre of the disc. A first concentric ring (40) of an adjacent pair of concentric rings has a surface configured to exhibit a first level of adhesion to the liquid. A second concentric ring (50) of the adjacent pair of concentric rings has a surface configured to exhibit a second level of adhesion to the liquid, and wherein the first level of adhesion is less than the second level of adhesion.

The purpose of the present disclosure is to provide a method for application of products in liquid or semiliquid state, such as chemicals for agricultural use and the like, using a rotating atomizer device, in such a way that the drops shall fall downwards in the form of fog over the crops due to the action of the force caused by its mass and gravity, in addition to the eventual momentum that centrifugal effect of the rotating parties that generate the drops may provide, wherein the method includes the following steps: individually regulate the voltage for the speed of the engines of each rotating atomizer device, modifying the parameter of the power supply of the engine to ensure that the speed of each rotating atomizer device is the correct one, measure the speed of the engine under its control and correct any deviation or separation from the programmed operating values.

An arrangement introduced into a motorized nebulizer equipped with a pneumatic nozzle for generating cold drops, which allows for the high efficiency of the application through the formation of a droplet spectrum within the range of sizes recommended by the World Health Organization (WHO) for the control of insects, in particular, mosquito vectors of human diseases, in flight, which is a spectrum with a median volumetric diameter (MVD) of less than 30 microns (μm).
