  • Patent number: 10165662
    Abstract: Provided is an ion generator that sends out air ions generated by applying high voltage between a discharge electrode and a counter electrode, the ion generator including: an air discharge port provided in a housing of the ion generator to send ejected air toward a region between the discharge electrode and the counter electrode; and an opening portion configured to discharge the generated air ions by the ejected air, in which the counter electrode is positioned on an upstream side of the flow of the ejected air with respect to the discharge electrode.
    Type: Grant

  • Patent number: 9674934
    Abstract: Provided is an ion generator that has a potential sensor provided integrally inside the main body of the ion generator, and that can measure, with the potential sensor, an electric field that reaches the potential sensor from a member from which static charge is to be eliminated, without being affected by an electric field between a discharge electrode and an opposing electrode. This ion generator comprises a discharge electrode, an opposing electrode, and a main body part including these electrodes, the ion generator sending out, toward a member from which static charge is to be eliminated, air ions generated by applying a high voltage between the electrodes.

  • Patent number: 8355237
    Abstract: A maintenance operation of an ion generator can be easily performed. A device main body has an inner case and an outer case, and the inner case having a support block and an air supply pipe is inserted into the outer case. An opposite electrode is detachably mounted in the support block from a front side of the device main body, and a discharge needle unit is detachably mounted from a reversed direction thereto. The discharge needle unit has a holder, in which the discharge electrode is provided, and a sleeve, which forms an ion generating space between the opposite electrode and the sleeve, is detachably mounted in the holder. Air supplied from an outside is supplied to the ion generating space via a flow path in the air supply pipe.

  • Patent number: 8035948
    Abstract: This static eliminator is used for eliminating static electricity from an object by ionizing the air to be blown to a charged object, and has a case 12 body provided with an air blow duct 15 for blowing out an ionized air, and an electric discharge module 27 being mounted detachably on the case body 12. The electric discharge module 27 has an electric discharge needle substrate 31 having a plurality of electric discharge needles 38 arranged straightly, and a surface panel 32 detachably mounted on the case body, and the electric discharge module 27 is mounted on the case body 12 by mean of a mounting screw member 36 in the portion of the surface panel 12. By dismounting the electric discharge module 27 from the case body 12, the electric discharge needles can be replaced.

  • Patent number: 7561403
    Abstract: A static eliminator capable of replacing a discharge needle and improving maintainability of the eliminator is disclosed. The static eliminator comprises: an air-guiding duct having a tubular portion provided with an outer electrode and a boss portion; and an electric discharge module detachably mounted on the tubular portion, wherein ionized air is supplied to the air-guiding duct by a fan of an air blower. The electric discharge module has a holder fitted in a boss portion and a plurality of discharge electrodes attached to the holder so as to protrude toward the outer electrode in an outer-radial direction. When foreign substances or the like adhere to a tip of the discharge electrode or when the discharge electrode deteriorates, the electric discharge module is detached from the boss portion.
