Abstract
An ion generator is capable of efficiently generating ions and includes a case accommodating an ion-generating element that generates ions by discharging electricity from a discharging needle electrode and a cover having openings for ion discharge. Resistive elements are disposed at peripheral portions of the openings, and the resistive elements are grounded. Since the resistive elements are grounded, the peripheral portions of the openings are prevented from being electrostatically charged. As a result, retention of ions at the openings is suppressed, and ions are efficiently generated and discharged.
Claims8
An ion generator comprising:
- a case;
- an ion-generating element provided in the case and including a discharging needle electrode and a ground electrode facing the discharging needle electrode;
- a cover included in the case and having an opening that faces the discharging needle electrode;
- and
- a grounded resistive element provided at a peripheral portion of the opening;
- wherein
- the resistive element is disposed on an outer surface of the cover.
