Title: Protective Breathing Apparatus For Viruses And Toxic Particles

Description:
BACKGROUND OF THE INVENTION 
     This Invention is based off of the Protective Breathing Apparatus by inventor of Peter Sing U.S. Pat. No. 4,815,458 which use simple filters to block larger particles such as, dust, pollen, etc. . . . which are not able to block much finer particles such as viruses, like COVID-19, which has a diameter of roughly 120 nanometers (nm). It does not catch the contaminants from user exhale, which will not stop the transmission of the COVID-19 virus. The most distinct difference is, the previous invention by Peter Sing does not kill the virus, or other living contaminants, as this new improved invention by Peter Sing does. This new virus exterminator will use a less dense filter by using disinfectant to kill the virus while processing the air. This new application will improve the previous invention. This new invention will possibly eradicate viruses, especially COVID-19 from the earth. Numberless situations exist in which wholesome air for breathing is not available without some means for removing the contaminants from the atmosphere. This is increasingly prevalent in today&#39;s society with the novel ‘Coronavirus’ at large. Normally, conditions for using a protective breathing apparatus are, but not limited to; industrial areas, mines, painting and cleaning operations, etc. . . . . Now, everyone in the world needs to wear a protective breathing apparatus in the form of face masks to enter the public world because the untreated air may contain life-threatening contaminants. 
     The protective masks available today may stop a virus from being inhaled or exhaled, but if it were to filter out a virus then that virus would be attached to the mask itself and remain alive for an undetermined amount of time. These face masks don&#39;t protect your eyes or even kill the virus. By purifying not only the air that is being inhaled, but also purifying the air being exhaled prevents an unknowingly infected person from releasing their contaminants back into the atmosphere, thus, stopping the spread of an infectious disease. 
     It is a primary object of this invention to provide an effective inexpensive apparatus for supplying purified healthful air for breathing, with protection and comfort for the eyes and face of the user at the same time. It is further an object of this invention to provide an apparatus easily portable and lightweight enough for prolonged wearing without discomfort. It is also an object of this invention to supply simultaneously the heads and faces of multiple users with air that has not only been freed of any harmful gaseous, liquid, solid, or infectious impurities but also adjusted in temperature for maximum user comfort. These and other objects will be explored in detail in the ensuing disclosure. 
     SUMMARY OF THE INVENTION 
     Atmospheric air is drawn into the intake which goes directly into the first fan, compressing and forcing the air through the first filter. The air then passes through a reducer to compress the air once more. The newly compressed and filtered air then passes into another fan but this time the air is combined with the disinfectant at a high rate of speed causing the air and disinfectant to separate through centrifugal forces. The separated disinfectant then drains into a reservoir to be re-used while the separated air is forced through another reducer to a chamber that has optional UV light or added heat. The newly purified air then passes through conduit means into the breathing hood and is inhaled by the wearer. The breathing hood encompasses the wearer&#39;s head entirely and is secured by a neck band around the wearer&#39;s neck. Newly purified air flows into the breathing hood, this current holds the hood out of contact with the wearer except for where it is secured with the neck band. After the wearer exhales the air it is expelled through an exhaust port which returns the expelled air back to the processing chamber to purify the air once more before releasing the exhausted air back into the atmosphere. 
     Optional provisions can be made to attach multiple breathing hoods to a single purifier allowing a plurality of breathing hoods to be supplied with clean, uncontaminated air from only a single purifier. Also, the incoming air supply may have temperature control for the user&#39;s optimal comfort. The purifier can be separated from the breathing hood allowing the user to attach the purifier to an air conditioning or heat pump unit. 
     The process chambers will compress the air before or after processing and before or after storing the air. Compressed air can be stored in at least one storage tank that will be either before or after the disinfection processing. Compressing air creates a smaller area needed to process air and disinfectant. Pressurized air and disinfectant forces the two to mix thoroughly. The device will use a small DC powered air pump to compress the air and/or disinfectant. Compressed air will be easier to mix with the disinfectant. Another solution to mix the air and disinfectant is the use of a spherical object inside of a conduit. The air and disinfectant will be forced to pass by the spherical object, forcing the two to collide and combine thoroughly. Another form of disinfection that can be applied is the use of a heating element. The air may be cooled/condensed in order to remove excess moisture after the air is processed. There can be a valve to regulate the pressure reaching the breathing hood. 
     Further filtration can be introduced by filling the intake conduit with packing materials; like mesh, cotton, plastic pellets, wood pellets, etc. . . . . This further filtration will allow for the air that is introduced to the processing chamber(s) will have already been removed of any larger toxic particulates. 
     Optional provisions can be made for the device to attach to an auxiliary powered air blower, such as a vacuum. The processor can be added to the motor of any vacuum and disinfect the air as it would with the portable device. There will be a regulator and/or compressor to limit the air flow from such a device. 
     These and other concepts of this invention will now be described in full detail in connection with the accompanying illustrative drawings, wherein:

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The protective breathing apparatus shown in  FIGS.  1 - 2    uses an electrical motor to draw air from the atmosphere through the intake  4 , which has a metallic, or non-metallic, mesh  5  at its threshold, as well as the exhaust air from the breathing hood via conduit  14 . Fan  6   a  aides in drawing in air from the intake  4  but also compresses the air, forcing air to pass through a filter  7   a  as well as a reducer into the next stage comprised of a fan with angled blades  8  to compress the air once more and to mix the air with the disinfectant (soap, alcohol, etc. . . . ) produced from the disinfectant reservoir  9 . The disinfectant reservoir  9  collects the disinfectant after it has been separated from the air through centrifugal forces  8  as well as gravity through the means of distillation  10  and stores disinfectant to be drawn back into the chamber to disinfect the passing air. Once the air is separated by centrifugal forces caused by fan  8  the compressed and separated air passes through another filter  7   b  and reducer into the distiller  10  to further separate any remaining disinfectant particles. The newly disinfected air passes through another filter  7   c  and reducer to be compressed by fan  6   b  and pass through a filter  7   d  and reducer into the heat/UV light chamber  11  to destroy any and all remaining contaminated particles in the air. The air passes a filter  7   e  and reducer to be released to the pressure regulation chamber  12  where pressure can be released, if it is too great for the conduit  13  or breathing hood in  FIG.  2   , through the pressure regulator  18 . The freshly purified air then passes through the conduit  13  to the breathing hood in  FIG.  2   . 
     Once the purified air reaches the end of the conduit  13  it is then released through the inlet  17   b  inside of the transparent plastic hood envelope  15  inflating the hood envelope so there is no contact with the wearer&#39;s head. The transparent plastic hood envelope  15  is attached to an easily adjustable and removable neck band  16  to secure the breathing hood to the wearer whilst insuring an impregnable seal. The fresh, clean, purified air is now safe to breathe. After the wearer inhales and exhales the cleaned air, the now sullied air is expelled through the exhaust port  17   a  to be returned through conduit  14  to the intake of the purifying device  4  to be purified once more before being reused in the apparatus or released into the atmosphere. The device is designed to draw in air from the atmosphere that may be polluted or contaminated (with dust, allergens, viruses, infectious disease, etc. . . . ) and create a safe and protected breathing environment for the user as well as anyone around the user. This is because the device only releases purified air. The user could have a very contagious illness or disease and still interact with others in a public setting because the contaminated air they exhale is cleansed before it is released into the atmosphere. This protective breathing apparatus would stop the transmission of any respiratory disease from person to person. This disclosure is intended to be illustrative; various substitutions and combinations of elements lie within the scope of its concepts and structures, which are defined and limited only by the ensuing claims.
