Abstract

A cartridge device containing UVC for air disinfection that comprises individual ultraviolet bulb, HEPA/Carbon filter, LED for detection of replacement, ballast and electrical components; cartridge is plugged into a backplane which allows for easy installation and servicing of all components. The backplane powers the device and can be encased in various configurations which can be used in multiple applications, including portable and permanent air treatment devices.

Claims

1. An air disinfecting system comprising:

a cartridge, having a length and a diameter, and interior chamber, an airflow inlet, an airflow outlet, a longitudinal axis, an ultraviolet light bulb disposed in the chamber and along the longitudinal axis of the cartridge, a filter disposed radially along the longitudinal axis within the chamber, a reflective coating disposed on the inside of the chamber, a ballast that supplies power to the ultraviolet light bulb, and an electrical connector disposed on the exterior of the cartridge and electrically connected to the ballast; and

,

an encasement, wherein the encasement includes, a base member having a first and second airflow orifice, a backplane disposed on the base member, a top member having an outlet orifice and an exhaust orifice and being disposed on the backplane, wherein the backplane is operably configured to receive the electrical connector of the cartridge and the cartridge inlet and outlet are axially aligned with the second airflow orifice of the base member and the outlet orifice of the top member, an impeller and electrical connections to supply electrical power to the impeller and the cartridge.

2. An air disinfecting system of claim 1, wherein the length and diameter of the cartridge have a ration of 3:

1.

3. An air disinfecting system as recited in claim 1, wherein the cartridge includes a seal around the airflow inlet and outlet.

4. An air disinfecting system of recited in claim 1, wherein the cartridge is fabricated from a light weight, durable, high impact, heat resistant material.

5. An air disinfecting system of recited in claim 1, wherein the electrical connector on the cartridge is a male type connector.

6. An air disinfecting system comprising:

a cartridge having a length and a diameter, wherein the length and diameter have a ratio of 3;

1, an interior chamber, an airflow inlet, an airflow outlet, a longitudinal axis, an ultraviolet light bulb disposed in the chamber and along the longitudinal axis of the cartridge, a filter disposed radially along the longitudinal axis within the chamber, a reflective coating disposed on the inside of the chamber, a ballast that supplies power to the ultraviolet light bulb, and an electrical connector disposed on the exterior of the cartridge and electrically connected to the ballast; and

,

an encasement, wherein the encasement includes, a base member having a first and second airflow orifice, a backplane disposed on the base member, a top member having an outlet orifice and an exhaust orifice and being disposed on the backplane, wherein the backplane is operably configured to receive the electrical connectors of the cartridge and the cartridge inlet and outlet are axially aligned with the second airflow orifice of the base member and the outlet orifice of the top member, an impeller and electrical connections to supply electrical power to the impeller and the cartridge.

7. An air disinfecting system as recited in claim 6, wherein the reflective coating of the cartridge is clear specular aluminum.

8. An air disinfecting system as recited in claim 6, the cartridge includes a seal around the airflow inlet and outlet.

9. An air disinfecting system as recited in claim 6, wherein the electrical connector on the cartridge is a male type connector.
