  • Publication number: 20060201016
    Abstract: A hair dryer with a static atomizing device is provided, which has the capability of generating an electrostatically charged microparticle mist of 3 nm to 100 nm. The static atomizing device has a pair of an atomizing electrode and a counter electrode, a tank for storing a liquid such as water; a liquid transport member for transport water from the tank to the atomizing electrode according to capillary phenomenon, and a voltage applying unit. When a high voltage is applied between the atomizing electrode and the counter electrode, while water being supplied to the atomizing electrode through the liquid transport member, the electrostatically charged microparticle mist is generated.

  • Publication number: 20060064892
    Abstract: In an electrostatic atomizing hairdryer, electrostatically atomized mist generated in an electrostatic atomizing unit is effectively scattered into airflow emitted from a main body of the hairdryer so that the mist can be sprayed to hair uniformly and a time necessary for treatment of hair can be shortened. A tank constituting the electrostatic atomizing unit is detachably provided on a portion in the vicinity of an outer periphery of the main body, and an electrode unit for generating the mist is provided in a path of airflow sucked in an inside of the main body so as to be insulated from heat of a heating unit by an adiabator. A mist emitting opening from which the mist is emitted is disposed on a plane substantially the same as and at substantially the center of an air exit opening of the main body. Thereby, the mist emitted from the mist emitting opening is effectively scattered into the airflow emitted from the air exit opening.
