Abstract

A personal pure air device where an air quality visualizer that can fit in a pocket like a pen samples ambient air quality for VOC'"'"'s, poisonous gases, ozone, and possibly bacterial or viral content. The invention can contain a personal air bottle containing pure compressed air which can be dispensed through a regulator and tube to a nozzle to provide a plume of pure are around the user'"'"'s nose and mouth providing a space of purified personal breathing air. The visualizer can be directly connected to the regulator to automatically start a flow of pure air when ambient air quality deteriorates, or the user can simply read the air visualizer and manually start the flow of pure air when desired through the use of valves.

Claims

1. A personal air supply system comprising:

an air visualizer means for determining ambient air quality;

a personal air bottle containing compressed purified air;

a nozzle for distributing purified air in a personal breathing space, said nozzle being coupled to said personal air bottle by a tube;

said personal air supply system dispensing purified air when said air visualizer determines reduced ambient air quality.

2. The personal air system of claim 1 further comprising direct connection between said air visualizer and said personal air bottle, said visualizer activating airflow when ambient air quality deteriorates.

3. The personal air system of claim 1 wherein said personal air bottle is metal.

4. The personal air system of claim 3 wherein said metal is steel.

5. The personal air system of claim 3 wherein said metal is aluminum.

6. The personal air system of claim 1 further comprising at least one light indicator of ambient air quality.

7. The personal air system of claim 6 further comprising an audio alarm indicator of ambient air quality.

8. The personal air system of claim 1 wherein said air visualizer contains a VOC sensor.

9. The personal air system of claim 1 wherein said air visualizer detects at least one poisonous gas.

10. A system for creating a pure air central breathing region around a user'"'"'s nose and mouth when ambient air quality deteriorates, this system comprising a personal pure air bottle containing pressurized pure air, a regulator attached to the air bottle for producing a low pressure continuous flow of pure air, a tube for transporting the pure air to a nozzle, the nozzle being located near the user'"'"'s nose and mouth.

11. The system of claim 10 further comprising an air visualizer with lights to inform the user when ambient air quality is deteriorating.

12. The system of claim 10 wherein the air visualizer contains at least on gas sensor.

13. The system of claim 12 wherein the gas sensor senses volatile organic compounds.

14. The system of claim 12 wherein the gas sensor senses at least one poisonous gas.

15. The system of claim 11 further comprising said air visualizer automatically starting said flow of pure air when said air visualizer detects deteriorating ambient air quality.

17. The method of claim 16 wherein said flow of pure air starts automatically when ambient air quality deteriorates.

18. The method of claim 16 wherein said flow of pure air is controlled manually and said ambient air quality is indicated with lights on an air visualizer.

19. The method of claim 18 further comprising an audio alarm on said air visualizer.

20. The method of claim 18 wherein said air visualizer detects at least one poisonous gas.

16. A method of providing a plume of pure air about a person'"'"'s face when ambient air quality deteriorates comprising:

sampling air to continuously determine ambient air quality by using a system of gas sensors;

starting a flow of pure air from a personal air bottle carried on a person when ambient air quality deteriorates;

causing said flow of pure air to form a plume of pure air around a person'"'"'s nose and mouth by using a tube and a nozzle;

stopping said flow of pure air when ambient air quality improves.
