  • Patent number: 10638823
    Abstract: A hair iron according to the present disclosure is configured to hold hair in a state in which a first hair holding surface and a second hair holding surface face each other. A first hair holder includes ion outlets configured to release ions generated by a discharge device. The discharge device includes a first electrode having a plurality of discharge electrodes. The first electrode includes an electrode body having a plate shape. The discharge electrodes are disposed on a side portion e end of the electrode body as the electrode body is viewed in a thickness direction thereof. The discharge electrodes include two types of discharge electrodes of which shapes are different from each other.

  • Publication number: 20090078800
    Abstract: There is provided an electrostatic atomizer that electrostatically atomizes a liquid supplied to a discharge electrode by electric discharge caused by an electric field formed in response to voltage application to the discharge electrode. The electrostatic atomizer has a high-voltage generation circuit that generates a pulse voltage to be applied to the discharge electrode, and the high-voltage generation circuit includes a high-voltage control circuit that converts an input AC signal to a pulse signal, and an igniter that steps up the pulse signal obtained by the high-voltage control circuit to a voltage value of the pulse voltage to be applied to the discharge electrode.

  • Publication number: 20080263887
    Abstract: A hair dryer with a nozzle designed to effectively spread out the wetted hair strands for enhanced drying capability. The nozzle is configured to have its interior space divided into a plurality of individual ducts by a separation plane extending radially about a center axis. A weak flow zone where no direct air flow is given from the nozzle is formed downstream of the separation plane and between strong flow zones respectively formed downstream of the individual ducts to flow the forced air flow directly therefrom. With the provision of the localized strong flow zones separated by the weak flow zone, the nozzle can develop a waved air flow of varying flow rate, thereby enabling to spread out the wetted hair strands and therefore increase chances of exposing the hair to the air flow for expediting the hair drying.

  • Patent number: 7120007
    Abstract: An ion generating unit is made compact, yet avoids the undesired arc discharge for successfully generating the ions. The ion generating unit includes a dielectric base having a length and carrying a needle electrode and a ground electrode. The needle electrode has a pointed tip and is adapted to receive a high electric voltage relative to the ground electrode for electrically charging particles present in the surrounding air. The dielectric base being a polyhedron having multiple faces including a first face and a second face which are different from each other and have the length of the dielectric base. The needle electrode is mounted on or in a closely adjacent relation to the first face, and has its pointed tip directing forwardly along the length of the dielectric base with the pointed tip receded from the front end of the base. The ground electrode is mounted at the front end of the base in longitudinally spaced relation with the pointed tip.
