Protective visored helmet with disinfected air flow property
View Patent ↗A protective visored helmet with disinfected air flow property used in order to prevent infection (virus, bacteria, allergen) agents in cases of high contagion (during the treatment of viral/bacterial infections with high risk of airborne transmission, epidemics, pandemics).
1. An air flow protective visored helmet configured to form a disinfected air flow curtain around a face of a user so as to filter air in an environment contaminated with pathogens or particles, the air flow protective visored helmet comprising:
an air fan adapted to draw air from the environment;
a first air chamber adapted to enclose air drawn from said air fan, said first air chamber having a curved surface that changes a direction of the air, said first air chamber having an inlet cover or base adapted to allow particles to subside or hit and adhere thereto;
a first surface being a lubricated antiseptic layer adapted to catch and neutralize pathogens that have subsided to a bottom surface of said first air chamber;
a HEPA filter cooperative with said first air chamber so as to filter air in said first air chamber and to vent the air from said first air chamber;
at least one first LED positioned on a reflective wall of said first air chamber, said at least one first LED adapted to disinfect germs or viruses from air reflected from the reflective wall, said at least one first LED emitting UVC radiation;
a second air chamber adapted to receive air from an outlet port of said first air chamber, said second air chamber having a curved variable diameter air channel that allows air to accelerate toward a gravitational pull in one direction and to decelerate in an opposite direction;
a second surface formed on a U-shaped base of said second air chamber, said second surface adapted to allow air to accelerate by passing through the curved variable diameter air channel and to rotate 180° with respect to the curved variable diameter air channel after passing through the U-shaped base so as to hold small panicles suspended by gravity in the air that is slowed down thereby, said second surface having a disinfectant chemical thereon;
at least one second LED positioned on an inner wall of the curved variable diameter air channel, said at least one second LED adapted to disinfect germs or viruses via UVC radiation on the reflected air;
a pipe connected to an outlet port of said second air chamber so as to deliver disinfected particle-free air from the outlet port of said second air chamber to a junction port;
a supply channel communicating with the junction port and adapted to pass the air from the junction port to the air flow protective visored helmet in order to form the air flow curtain; and
an air blow nozzle cooperative with the air flow protective visored helmet and adapted to transmit the air unidirectionally from the air flow curtain in the air flow protective visored helmet.
2. The air flow protective visored helmet of claim 1 , further comprising:
a controller unit cooperative with said first air chamber and said second air chamber so as to change a flow rate of the air therein.
