Abstract
An ion generator () generally includes: a shielding shell (), a cathode device (), and an annular anode (). The shielding shell has a first end (), an opposite second end () and a main body () therebetween. The first end has an electron-input hole (). The second end has an ion-output hole (). The main body has a gas inlet () for introducing an ionizable gas (). The cathode device faces the electron-input hole for emitting electrons to enter the shielding shell so as to ionize the ionizable gas thereby generating ions. The cathode device includes a conductive base () and at least one field emitter () thereon. The annular anode is arranged in the shielding shell. The anode is aligned with the ion-output hole.
