Abstract

Provided is an ion emission device comprising a plurality of discharge electrodes, whereby it is possible to ensure a diselectrification speed and a positive-negative ion balance when in adjacent use, and which has superior diselectrification performance. A diselectrification device comprises a plurality of discharge electrodes (10) which respectively generate positive or negative ions, a fan (14) which ventilates to the outside the ions which are generated from the discharge electrodes (10), and a metal net (15) which is positioned in a ventilation port of the ions. The metal net (15) further comprises first mesh parts (N1), and second mesh parts (N2) with a wider mesh than that of the first mesh parts (N1). In a projected state, the discharge electrodes (10) are located at the first mesh parts (N1).

Description

technical field [0001] The present invention relates to an ion generator that generates positive ions and negative ions, and a static elimination device that removes the charge of a charged object by the positive ions and negative ions. Background technique [0002] The object technical field which uses an ion generator, and its application field (apparatus) relate to various aspects. Mainly used in industry can include electrophotographic charging devices, air disinfection, sterilization or deodorization devices, electronic dust collection devices, ozone generators, electrostatic spraying devices, etc., for example, in the manufacturing process of liquid crystal display devices and semiconductor devices, etc. It is used as a static elimination device to prevent static electricity barriers in the clean room. [0003] The static elimination device eliminates static electricity by irradiating a charged object with positive and negative ions generated by ionizing surrounding a...
