Abstract
A discharge device includes discharge electrode, counter electrode, and a voltage application device. Discharge electrode includes distal end portion. Counter electrode is disposed so as to face distal end portion of discharge electrode with a gap provided therebetween. The voltage application device applies a voltage between discharge electrode and counter electrode to generate a discharge between discharge electrode and counter electrode. Discharge electrode protrudes toward counter electrode. Counter electrode includes discharge portion where a discharge occurs between discharge portion and distal end portion of discharge electrode. Discharge portion extends along a circumference centered at distal end portion of discharge electrode.
Claims9
A discharge device comprising:
- a discharge electrode including a distal end portion;
- a counter electrode disposed so as to face the distal end portion of the discharge electrode;
- and
- a voltage application device that applies a voltage between the discharge electrode and the counter electrode to generate discharge between the discharge electrode and the counter electrode,
- wherein
- the counter electrode includes an opening and a ring-shaped discharge portion that is provided on a peripheral edge of the opening and serves as a base point of discharge, and
- a dielectrically broken discharge path is intermittently formed between the distal end portion of the discharge electrode and the ring-shaped discharge portion of the counter electrode, while the distal end portion of the discharge electrode serves as a base point on one end side of a discharge path, and the ring-shaped discharge portion of the counter electrode serves as a base point on the other end side of the discharge path.
