Abstract
An electro-hydrodynamic (EHD) device is provided in combination with a bottle. The bottle comprises a container including a liquid formulation to be comminuted into a spray of droplets and a wick extending into the container. The wick has an end portion. The EHD device comprises a first conductive element at a first electrical potential. The EHD device further comprises a second conductive element at a second electrical potential. The first and second electrical potentials at the first and second conductive elements result in a strong electric field being generated in the vicinity of the first element end section. The bottle may be removably coupled to the EHD device.
Claims

4. The EHD device as set out in claim 2, wherein said first conductive element comprises a cylinder-shaped element into which said wick end portion is positioned, said cylinder-shaped element having at least one end section defining at least one EHD
comminution site.
5. The EHD device as set out in claim 2, wherein said first conductive element comprises a crown-shaped element into which said wick end portion is positioned, said crown-shaped element having a plurality of end sections defining a plurality of EHD comminution sites.
6. The EHD device as set out in claim 1, wherein said first conductive element comprises a plurality of capillary tubes formed from a high surface energy, electrically conductive material, and having end sections defining a plurality of EHD comminution sites.
7. The EHD device as set out in claim 1, wherein said EHD device further comprises a dielectric shroud positioned between said first and second conductive elements
8. The EHD device as set out in claim 7, wherein said second conductive element is located between said container and said first conductive element and generates a cloud of ions that forms a virtual electrode cloud near said first element end section.
9. A process for generating a spray of droplets from a liquid formulation using an electro-hydrodynamic (EHD) device in combination with a bottle comprising:
providing a removable bottle comprising a container including a liquid formulation to be comminuted into a spray of droplets and a wick extending into said container, said wick having an outer portion such that liquid formulation is conveyed along the wick to the wick outer portion via capillary action;
