Novel portable, lightweight, and wearable respirator

A respirator that is portable, and lightweight comprising:

• a wearable device;
• and
• a face mask;
• said wearable device that is attached to a body of a wearer comprising:
• an inlet assembly that receives an air from an environment by a first fan and filters said air by a first filter;
• an exhaust assembly that receives a contaminated air from an interior of said face mask by a second fan and filters it by a second filter before releasing it to said environment;
• an oxygen tank that stores an oxygen that is compressed;
• a power housing to hold a battery, and a control circuit;
• a regulator that receives said oxygen from said oxygen tank, adjusts a pressure of said oxygen within said regulator before injecting it into said inlet assembly to be mixed with said air that is filtered by said first filter to become an enhanced air;
• said regulator comprising:
• an inlet valve to receive said oxygen from said oxygen tank;
• a container that holds said oxygen from said oxygen tank received from said inlet valve;
• a sensor inside said container to measure said pressure of said oxygen within said container and deliver it to said control circuit;
• an airbag inside the container that adjusts said pressure of said oxygen within said container by using at least one of an inflation process, and a deflation process under the control of said control circuit;
• and
• an outlet valve to deliver said oxygen that is inside said container after adjustment of said pressure to the inlet assembly;
• said face mask is connected to the wearable device by two air tubes, a first air tube receiving said enhanced air from said inlet assembly and a second air tube delivering said contaminated air to said exhaust assembly.
