Abstract

An ozone generator cartridge 60 suitable for a sterilization, decontamination and/or sanitation device. The cartridge comprises a sealable housing 60 for providing a corona discharge, the housing containing at least one power supply unit 64 and at least one inlet 65 for connection to an oxygen or air supply, the cartridge including at least part of at least one ozone conversion cell 63 attached to and extending from an external surface of a wall of the sealed housing, the conversion cell extending into a delivery conduit 52 of a decontamination device that leads to at least one discharge outlet 16.

Claims

1. An ozone generator cartridge comprising:

a sealable housing for providing a corona discharge that comprises;

a plurality of walls defining a cavity, wherein one of the plurality of walls comprises a mounting plate, and wherein the mounting plate comprises an internal surface within the cavity and an external surface outside the cavity that defines an exterior wall of the housing;

at least one power supply unit within the cavity and directly attached to the inner surface of the mounting plate; and

at least one inlet within the cavity for connection to an oxygen or air supply; and

at least one ozone conversion cell external to the housing and directly attached to and extending from the external surface of the mounting plate, wherein the ozone generator cartridge comprises the at least one ozone conversion cell directly attached to and extending from the external surface of the mounting plate and the at least one power supply unit directly attached to the inner surface of the mounting plate, and wherein the ozone generator cartridge is configured to sealably engage with an opening of a second housing.

2. An ozone generator cartridge as claimed in claim 1 wherein at least one ozone conversion cell directly attached to and extending from the external surface of the mounting plate comprises at least one pair of electrodes and a dielectric.

3. An ozone generator cartridge as claimed in claim 1 wherein the at least one ozone conversion cell extends substantially orthogonally from the external surface of the mounting plate.

4. An ozone generator cartridge as claimed in claim 1 wherein the housing comprises a body with a cover.

5. An ozone generator cartridge as claimed in claim 4 wherein the body comprises the mounting plate, with one long side wall and two short side walls extending substantially orthogonally from the mounting plate, and the cover comprises a generally L-shaped panel, a short limb of the cover making up an opposing long side wall in the assembled housing.

6. An ozone generator cartridge as claimed in claim 4 wherein the body comprises the mounting plate with one long side wall and two short side walls extending substantially orthogonally from the mounting plate and the cover comprises a generally L-shaped panel, a short limb of the cover making up an opposing long side wall in the assembled housing, and wherein components of the ozone generator cartridge that must not be exposed to high levels of ozone are directly fixed to the internal surface of the mounting plate which is sealable within the housing by means of the cover.
