Abstract

A system and method for sanitizing air is disclosed. Atmospheric air is drawn into the system by a fan. The air is passed through a series of baffles to mix the air and reduce speed. The air is exposed to an emitter, such as UV-C light, to sanitize contaminants and then exhausted. The sanitized air drawn into the system and exhausted to the atmosphere without exposing UV-C light to the atmosphere.

Claims (44)

1 . A system for sanitizing air, comprising:

a main body;

a baffle assembly,

wherein the baffle assembly includes a fan assembly, an inner baffle plate, an end baffle plate, and an emitter;

wherein said fan assembly includes fans, a front fan mount plate, a mid-baffle and internal baffle to block electromagnetic waves emitted by the emitter from escaping into an environment within which the system is located,

wherein the inner baffle plate includes at least a first hole to allow air to flow through the inner baffle plate and at least a second hole,

wherein the emitter passes through the second hole of the inner baffle plate and is mounted to the internal baffle,

wherein the fans are mounted to the front fan mount plate; and

wherein the inner baffle plate, and mid-baffle include angled protrusions to alter air flow.

2 . The system of claim 1 , further comprising a divider, an end cap assembly, or a combination thereof, to facilitate blocking of the electromagnetic waves from escaping into the environment.

3 . The system of claim 1 , wherein the baffle assembly is configured to mix air drawn into the system to increase an efficacy of sterilization of the air by the electromagnetic waves.

4 . The system of claim 1 , further comprising a rear fan assembly configured to exhaust the air after the air has been sanitized by the system.

5 . The system of claim 1 , further comprising a control assembly for controlling operating of the emitter, the fan assembly, or a combination thereof.

6 . The system of claim 1 , further comprising an electronics panel assembly configured to monitor operation of the system.

7 . The system of claim 6 , wherein the electronics panel assembly is further configured to facilitate communication of the system with a remote system, device, or a combination thereof.

8 . A system for sanitizing air, comprising:

a main body;

a baffle assembly,

wherein said baffle assembly includes a fan assembly, a plurality of mixer plates, and an emitter;

wherein the fan assembly includes fans and a front fan mount plate,

wherein the fans are mounted to the front fan mount plate,

wherein the plurality of mixer plates include protrusions to alter air flow and at least one hole, wherein the emitter passes through the plurality of mixer plates through the at least one hole.

9 . The system of claim 8 , further comprising a rear fan assembly configured to exhaust air from the system into an environment.

10 . The system of claim 8 , wherein a subset of the mixer plates include different protrusions from another subset of the mixer plates to facilitate mixing of the air.

11 . The system of claim 8 , wherein the emitter is configured to emit electromagnetic waves to facilitate sanitization of the air within the main body of the system.

12 . The system of claim 8 , further comprising an end assembly through which the air enters the system.

13 . The system of claim 8 , wherein the mixer plates include a plurality of protrusions to facilitate mixing of the air, generation of turbulence of the air, slowing down the air, or a combination thereof.

14 . The system of claim 8 , further comprising a top tube and a bottom tube for housing components of the system.

15 . A method of sanitizing air, comprising:

taking in air from an atmosphere by utilizing a fan assembly of a system;

mixing the air by passing the air through a baffle assembly of the system;

exposing the mixed air to ultraviolet light emitted by an emitter of the system to sanitize the air;

obtaining sensor data from at least one sensor of the system;

detecting viruses, bacteria, pathogens, and/or organisms utilizing the sensor data;

determining a purification status utilizing the sensor data;

adjusting a rate of sanitization of the mixed air based on the sensor data;

exhausting the sanitized air to the atmosphere;

wherein the baffle assembly includes an inner baffle plate, said inner baffle plate includes at least a first hole to allow air to flow through the inner baffle plate and at least a second hole to allow the emitter to pass through the inner baffle plate; and

wherein the inner baffle plate includes angled protrusions to alter air flow.

16 . The method of claim 15 , further comprising facilitating turbulence of the air by utilizing the baffle assembly of the system.

17 . The method of claim 15 , further comprising reducing a velocity or speed of the air by utilizing the baffle assembly of the system.

18 . The method of claim 15 , further comprising utilizing a divider, an end cap assembly, or a combination thereof, to block the ultraviolet light from escaping the system.

19 . The method of claim 15 , further comprising redrawing in the air from the atmosphere into the system to further sanitize the air.

20 . The method of claim 15 , further comprising facilitating activation of the system, deactivation of the system, control of the system, or a combination thereof, by utilizing a device communicatively linked to the system.
