Patent ID: 7854403

Claim:
An electrostatically atomizing device comprising a housing and an electrostatically atomizing unit accommodated within said housing, said electrostatically atomizing unit comprising: an emitter electrode; an opposed electrode disposed in opposite relation to said emitter electrode; water supply means configured to supply water to said emitter electrode; and an atomizing barrel configured to surround said emitter electrode, said atomizing barrel being formed at its one axial end with a discharge port exposed to exterior of said housing; a high voltage source being disposed within said housing and configured to apply a high voltage between said emitter electrode and said opposed electrode in order to electrostatically atomize the water supplied to emitter electrode for generating charged minute water particles and discharge said charged minute water particles through said opposed electrode out of said discharge port; wherein said water supply means comprising a heat exchanger having a cooling section and a heat radiator section, said cooling section cooling said emitter electrode to develop condensed water on said emitter electrode; said housing including a fan configured to generate a forced air flow for cooling said heat radiator section, and a straight flow passage configured to direct said forced air flow and to have said heat radiator section exposed therein, said atomizing barrel of the electrostatically atomizing unit being formed with an air inlet configured to introduce said air flow for carrying a mist of the charged minute water particles on said air flow and releasing it out of said housing, said electrostatically atomizing unit and said high voltage source being arranged on opposite sides of said flow passage, a first air intake port being provided to feed said forced air generated by said fan into said electrostatically atomizing unit, a second air intake port being provided to feed said forced air flow into said flow passage, a third air intake port being provided to feed said forced air into said high voltage source, and said first air intake port and said third air intake port being positioned upstream of said second air intake port.
