Claims:1. A mask for terminating virus which uses high DC voltage and UVC.
Wear the mask carefully and switch on the power circuit to turn the mask on.This mask is washable and rechargeable.
2. A method as claimed in claim 1, this mask cannot be use at petrol pumps or fuel stations due to the live high voltage ioniser
3. A method as claimed in claim 1, increasing the battery voltage beyond 6v maybe dangerous but you can increase the battery MAH for running it for a longer time.
4. A method as claimed in claim 1, this system does not produce any pollution
5. A method as claimed in claim 1, can be reused because of its rechargeable battery
6. A method as claimed in claim 1, can be washed by removing the electrical components which is in a form of plugin system.
7. A method as claimed in claim 1, this system works on the principle of UVC disinfection and Cold Plasma.
8. A method as claimed in claim 1,this is a reusable mask.
9. A method as claimed in claim 1, this mask is safe because its completely made up of plastic and rubber, as well all know rubber and plastics are a bad conductor of electricity
10. A method as claimed in claim 1, the electrical parts aren’t waterproof.
, Description:EVTM is a device which uses UVC & Corona Discharge Effect to terminate the virus. The mask uses a high voltage DC generator to produce 2500V which is live inside the air inlet valve. When we breath, the air passes through the ionising chamber from the DC air pump where the air gets ionised by the effect of Cold Plasma as a result the protein wall of the virus breaks down resulting in its termination. But for any condition if the virus manages to survive it goes to the UVC chamber with the air where it is killed with the rays of UVC as we all know UVC is used for terminating the COVID-19 and its used in hospitals and hotels for sanitization purpose. This UVC light can be dangerous if comes in contact with our skin so we have used a closed opaque chamber to protect it from affecting our skin. There is a black biological sponge in between the mask and UVC so that the rays does not reach to our face. Above the biological sponge there are the three layers of N95 protection which can be replaced after a certain use. The air passes through all of the filtration layers by a forced air pump and finally reaches our nose for breathing. During exhaling period there are two one sided valve which can only release the exhaled air from the mask to the environment. We cannot use those valves for inhaling purpose. This mask is washable and also rechargeable. The mask is firstly charged using a 230v-50hz AC supply, the PCB on the high voltage generator steps down the voltage and charges the battery for its portable use. After getting it charged for 1hour we can use it, when we switch on the PCB the high voltage starts generating and that high voltage is discharged to the ioniser chamber where there are two pin attachments with a little bit of air gap between them which helps it to generate the spark. At one of the sides there are the connection for UVC through which it powers 4 UVC lights (100-280nm) inside the closed opaque chamber which are sufficient enough for disinfecting but still if we increase the power of UVC it can prove better performance. The input voltage for the UVC LED is from 3V to 3.6V max. There are two modes of this PCB, switch down – power off, switch in middle – only ioniser, & switch in the top UVC with ioniser. This ioniser can be stopped by switching off the safety switch as described in the diagram FIG-3. According to theory and research work we found it that Cold Plasma can kill 99.9% of air borne virusesand UVC is also used for terminating COVID-19. We have used both the electrical technologies to make this mask so that it can prove effective on the COVID-19. To get a long running time we can increase the MAH of the battery so that it can easily give a good backup so that it can be used for several hours.
