Abstract

A self-cleaning ion generator device includes a first portion with a base portion that extends to an outer edge and a first pair and a second pair of opposed sidewalls extending upwardly from the outer edge and intersect at corners, forming a cavity therein. A second portion includes a base portion that extends to an outer edge selectively secured to the first portion forming a housing. At least one ion emitting device extending from the housing, and at least one cleaning apparatus for cleaning the at least one ion emitting device.

Claims (10)

1. A self-cleaning ion generator device, comprising:

a housing defining a cavity therein;

at least one ion emitting device extending from the housing; and

at least one cleaning apparatus configured to rotate to clean the at least one ion emitting device.

2. The self-cleaning ion generator device of claim 1 , further comprising a grate surrounding the at least one ion emitting device and the at least one cleaning apparatus.

3. The self-cleaning ion generator device of claim 1 , further comprising a motor housed within the cavity and engaged to a drive gear, wherein a gear is engaged to the at least one cleaning apparatus, wherein the drive gear is engaged to the gear of the at least one cleaning apparatus.

4. The self-cleaning ion generator device of claim 1 , wherein the at least one ion emitting device has a top portion and a bottom portion, wherein the top portion extends above the housing and the bottom portion is disposed within the cavity of the housing.

5. The self-cleaning ion generator device of claim 1 , further comprising at least two ion emitting devices spaced apart and extending from the housing.

6. The self-cleaning ion generator device of claim 1 , further comprising at least one cleaning head disposed on the at least one cleaning apparatus for cleaning the at least one ion emitting device.

7. The self-cleaning ion generator device of claim 1 , wherein the at least one ion emitting device consists of a plurality of bristles extending therefrom.
