An atomization device comprises a conduit containing liquid to be
atomized, a spray electrode (1) and a discharge electrode (3). Each
electrode is adjacent to a dielectric (5) and they are connected in an
electrical circuit (10) to enable a potential difference to be applied
between them to atomize the liquid and to generate charge carriers of a
first polarity in the proximity of the spray electrode (1) and ions of a
second polarity in the proximity of the discharge electrode (3). Some of
the first polarity charge carriers deposit on the dielectric adjacent to
the spray electrode (1) and some of the second polarity ions deposit on
the dielectric (5) adjacent to the discharge electrode (3) so that the
atomized liquid is repelled from the dielectric (5) adjacent to the spray
electrode (1) and electrically discharged by second polarity ions that
are repelled by the dielectric (5) adjacent to the discharge electrode
(3).
