  • Patent number: 7478640
    Abstract: A hair iron can give hair a sufficient amount of negative ions. The hair iron has a grip, and a hair-care section connected to the grip, having a heater for generating heat to hair for hair dressing. Further, it has a negative ion generator which generates negative ions due to discharge around an electrode therein to emit them toward hair held by the hair-care section. The hair-care section has a bar-like shape, and the heater is fixed to an outer surface of the bar-like shape. Then, by winding hair to the hair care section in the hair iron, hair dressing can be performed efficiently.

  • Patent number: 7171970
    Abstract: A hair setting instrument is provided which can set hair easily by supplying charges through a separate path. In concrete, the hair setting instrument comprises a mechanism for setting hair of a user, and an electrostatic charger which supplies charges to a body of the user for electrostatic charges generated by a movement for setting the hair. The electrostatic charger has a charging circuit which generates a predetermined voltage, and a charging plate electrically connected to the charging circuit. Wide spreading of the hair, electrostatic cling to the face or the like, dry hair, and the damage to the hair due to charging can be prevented. Further, for example, the body of hair can be decreased by supplying negative charges when the hair is charged with positive electrostatic charges.

  • Patent number: 6907888
    Abstract: An ion generator includes a needle electrode and a ground electrode cooperable with the needle electrode to generate a corona discharge in the air to produce ions. The ground electrode is disposed so as to surround an imaginary extension of a longitudinal axis of the needle electrode and has a portion thereof depleted to provide a split region defined therein. A hairbrush utilizing the ion generator is also disclosed.

  • Patent number: 5983903
    Abstract: A hair iron is provided which includes a hair curling body having an outer peripheral surface on which hairs are wound, a clip for holding the hairs between the inner surface of the clip and the outer peripheral surface of the hair curling body and a heater for heating the hair curling body. The clip is made of low heat conductive materials. A plurality of rib-shaped guards, which extend in a circumferential direction of the hair curling body, are provided at least on an area of the outer peripheral surface of the hair curling body other than the area facing the clip. The guards are made of low heat conductive materials. The guards are disposed at certain spaced intervals in an axial direction of the hair curling body.
