Embodiment Construction

[0026] Embodiments of the present invention will be described below based on the drawings.

[0027] first, figure 1 It is a schematic configuration diagram showing the main part of the first embodiment of the present invention. exist figure 1 In , reference numeral 10 is, for example, a case substrate of a corona discharge type ion generator installed on a ceiling surface of a clean room, and a discharge electrode 1 is mounted on the substrate 10 along a vertical direction. The substrate 10 is formed of an insulating material such as plastic.

[0028] The mounting structure of the discharge electrode 1 mounted on the illustrated substrate 10 is always a conceptual structure. Although not shown, the discharge electrode 1 may be held by an electrode holder and the electrode holder may be detachably mounted on the substrate 10. structure. Since these specific installation structures are not the gist of the present invention, descriptions are omitted here.

Abstract

The invention provides a corona discharge type ionizer, capable of effectively supplying the ions generated around a discharge electrode toward an anti-static object direction with a simple and low-cost structure. The corona discharge type ionizer supplies the ions generated around the discharge electrode (1) for the anti-static object (W) by the corona discharge to prevent the static, the coronadischarge type ionizer has an ion reflection part (2) electrically connected with the discharge electrode (1), the electric field is generated by applying the voltage with the same polarity as the discharge electrode (1) for the ion reflection part (2), so that the ions generated around the discharge electrode (1) can be effectively moved toward the anti-static object (W) direction.

Description

technical field [0001] The present invention relates to a corona discharge type ion generator that efficiently supplies positive ions or negative ions generated around a discharge electrode (emitter) to an object to be destaticized by corona discharge. Background technique [0002] In the corona discharge type ionizer, sometimes there are cases where the positive ions or negative ions generated around the discharge electrode adhere to the insulating casing supporting the discharge electrode, etc., so that the generated ions cannot be sufficiently discharged to the object to be destaticized. supply. [0003] Devices described in Patent Document 1, Patent Document 2, and the like are known as corona discharge-type ion generators aimed at solving such a problem. [0004] In the ion generator described in Patent Document 1, the ring-shaped ground electrode is arranged below the discharge electrode, and a pair of electrodes for electric field formation is provided below the grou...
