Abstract

Claims (19)

1 . A device for generating ions, comprising:

a housing with a first portion and a second portion having a cavity therein;

a first electrode and a second electrode for emitting ions;

an electrode cleaning apparatus slidingly disposed within the cavity of the housing configured to contact both the first electrode and the second electrode, the electrode cleaning apparatus contains an axially extending slot that is slidingly engaged to a motor, causing the electrode cleaning apparatus to contact the first electrode and the second electrode for cleaning.

2 . The device for producing ions according to claim 1 , wherein the motor is disposed within the housing.

3 . The device for producing ions according to claim 1 , wherein the electrode cleaning apparatus contains two spaced-apart emitter holes and an electrode of the device for producing ions is positioned adjacent each emitter hole of the cleaning apparatus.

4 . The device for producing ions according to claim 1 , wherein the device has a width between about 20 mm to about 30 mm.

5 . A device for generating ions, comprising:

a housing with a first portion and a second portion having a cavity therein;

a first voltage wire and a second voltage wire electrically coupled to an ionization module;

a first electrode electrically coupled to the first voltage wire configured to emit ions and a second electrode electrically coupled to the second voltage wire configured to emit ions; and

an electrode cleaning apparatus slidingly disposed within the cavity of the housing containing a first emitter hole and a second emitter hole spaced-apart from each other and a first cleaning flange disposed adjacent the first emitter hole and a second cleaning flange disposed adjacent the second emitter hole, wherein the first electrode is positioned adjacent the first emitter hole and the second electrode is positioned adjacent the second emitter hole, the first cleaning flange is configured to contact the first electrode and the second cleaning flange is configured to contact the second electrode, the electrode cleaning apparatus contains an axially extending slot that is slidingly engaged to a drive wheel engaged to a motor, causing the first cleaning flange to contact the first electrode and the second cleaning flange to contact the second electrode for cleaning.

6 . The device for producing ions according to claim 5 , wherein the motor is disposed within the housing.

7 . The device for producing ions according to claim 5 , wherein the device has a width between about 20 mm to about 30 mm.

8 . The device for producing ions according to claim 5 , further comprising a knob disposed on the drive wheel that is received within the axially extending slot of the electrode cleaning apparatus and configured to slide within the axially extending slot of the electrode cleaning apparatus.

9 . The device for producing ions according to claim 5 , wherein the first emitter hole and the second emitter hole have a square shape.

10 . The device for producing ions according to claim 5 , wherein the motor contains a rotational shaft engaged to the drive wheel for rotating the drive wheel.

11 . The device for producing ions according to claim 5 , further comprising a mounting member for mounting the device.

12 . The device for producing ions according to claim 11 , wherein the mounting member is selectively secured to the device and includes a base member and a side member.
