摘要： Provided is a discharge device that can improve the efficiency of generating reactive species. The discharge device includes a discharging unit, which has a tip end and discharges from the tip end in response to an application of a voltage, an induction electrode, which forms an electric field between the induction electrode end the discharging unit, and a second electrode, which is disposed between the discharging unit and the induction electrode and receives a voltage having a polarity the same as a polarity of the voltage applied to the discharging unit.

摘要： An ion generating device includes a high voltage transformer, a discharge electrode connected to a terminal of the high voltage transformer on a secondary side, and an induction electrode that generates ions between the induction electrode and the discharge electrode and is connected to a terminal of the high voltage transformer on the secondary side. A first conductive path includes the terminal and extends from the terminal to the discharge electrode and a second conductive path includes a terminal and the induction electrode. Part of the first conductive path is located in proximity and opposed to part of the second conductive path.

摘要： Each of first to fourth needle-like electrodes is arranged such that a direction of extension thereof is parallel, and generates ions by discharge. Through a space, a gas for conveying the ions generated by the first to fourth needle-like electrodes flows. Needle tips of the first needle-like electrode and the second needle-like electrode protrude from a first wall surface that forms the space, are spaced apart from each other, and are arranged in line in the space. Needle tips of the third needle-like electrode and the fourth needle-like electrode protrude from a second wall surface that forms the space and faces the first wall surface, are spaced apart from each other, and are arranged in line in the space. The first needle-like electrode and the fourth needle-like electrode generate positive ions, and the second needle-like electrode and the third needle-like electrode generate negative ions.

摘要： Provided is a discharge device that can improve the efficiency of generating reactive species. A discharging unit that discharges in response to an application of a voltage protrudes from a housing. The discharging unit is disposed in a duct through which gas flows. An upstream support is disposed upstream of the discharging unit in a direction of gas flow without overlapping the discharging unit. The upstream support protrudes further from the housing than the discharging unit. The upstream support includes a root portion joined to the housing. The root portion includes a widened portion that is disposed in the duct and that protrudes toward the discharging unit when viewed in the direction of gas flow.

摘要： An ion generator includes a high-voltage transformer having a secondary side that is not grounded; a discharge wire-pattern; an induction wire-pattern; a discharge electrode connected to a first terminal via the discharge wire-pattern, the first terminal being disposed on the secondary side of the high-voltage transformer; and an induction electrode connected to a second terminal via the induction wire-pattern, the second terminal being disposed on the secondary side of the high-voltage transformer. The first terminal has a first width. The discharge wire-pattern includes a discharge wide region having a second width greater than the first width. The discharge wide region and the induction wire-pattern at least partly overlap each other in plan view.

摘要： An ion generating device (1) includes discharge electrodes (21⋅22) each having a plurality of electrically conductive members (25⋅26) which form respective tip surfaces (36⋅37). A longer dimension direction of the tip surfaces (36⋅37) is nonparallel to an air sending direction (A). This allows for efficient release of ions.
