Abstract
A carrier is used to carry a liquid, and a high voltage is applied between a discharge end of the carrier and an opposed electrode to emit ionized liquid particles. The carrier has a liquid collecting end opposite to the discharge end to feed the steam of the liquid from a steam generator, condensing the liquid therearound, and feeding the condensed liquid to the discharge end. Accordingly, even when the liquid contains cations such as those of Ca and Mg, the steam of the liquid can extremely reduce the content of these impurities, avoiding the precipitation of the impurities at the discharge end of the carrier to assure stable electrostatic atomization.
Claims7
An electrostatically atomizing device comprising:
- a capillary carrier having a liquid collecting end and a discharge end opposite of said liquid collecting end, said liquid collecting end collecting a liquid for feeding the liquid through said carrier to said discharge end,
- a first electrode electrically charging said liquid,
- a second electrode opposed to said discharge end,
- a voltage source applying a voltage across said first and second electrodes to thereby electrostatically charge the liquid at said discharge end and emitting the said liquid in the form of tiny ionized particles,
- a steam supply that provides a steam of said liquid and feeding said steam to said liquid collecting end of said carrier for condensation of said liquid therearound in order that the condensed liquid is fed through said carrier to said discharge end.
