DETAILED DESCRIPTION OF THE INVENTION

[0040] In this detailed description, the preferred embodiments of the invention are merely described for a better understanding of the inventive protective visored (16) helmet with disinfected air flow property.

[0041] The inventive helmet filters the air in a patient room or in an environment that is stipulated to be contaminated from the pathogens and particles and forms an air curtain/flow around the face of the user, preventing the exposure to the contaminated air thereof.

[0042] The inventive helmet generally consists of 3 parts. FIG. 1, FIG. 2, FIG. 3 demonstrates the 1st, 2nd, and 3rd parts, successively; and the 1st and 2nd Parts are responsible for Filtering and disinfection processes, and the 3rd Part is responsible for isolation from the contaminated environment.

[0043] Firstly, air is drawn into the air chamber-1 (3) by means of the air fan (7). Air fan (7) is compatible with Li-Ion Battery or other battery types. Suction power of the air fan (7) is adjustable. This allows the control of the air velocity. The air sucked in the air chamber-1 (3) first encounters the 180-degree curved surface of the air chamber-1 (3). The air which encounters the curved surface ricochets and being filtered from its big particles by hitting the surface-1 (5) on the bottom surface of the air chamber-1 (3). Surface-1 (5) is a lubricated antiseptic layer that catches the particles filtered and neutralizes the pathogens.

[0044] The air filtered from big particles passes through the HEPA filter (6). The said HEPA filter (6) is a High Efficiency Particulate Arresting filter that retains the particles and droplets of 1 micron and above. The air passed through the hepa filter (6) is vented into the air chamber-1 (3).

[0045] Led-1 (8) is located on the inner reflective wall of the air chamber-1 (3). Led-1 (8) has UVC (Ultraviolet C) properties and provides UVC-radiation. The air entering the air chamber-1 (3) is disinfected against germs and viruses with the radiation provided by at least one Led-1 (8). The air flow radiated by the Led-1 (8) is accelerated and transmitted to the outlet port (10). Filtering and disinfection of the particles is provided by the change of air, gravity and air flow direction in the air chamber-1 (3). Outlet port (10) of the air chamber-1 (3) has an inclined and narrowing structure. By means of its structure, the air flow accelerates before the evacuation from air chamber-1 (3).

[0046] The accelerated air is then delivered to the air chamber-2 (11) from the outlet port (10) of the air chamber-1 (3). The air chamber-2 (11) consists of corrugated air channels (20). The air chamber-2 (11) provides variable air flow rate through the corrugated air channels (20). As seen in FIG. 2, corrugated structure of the air chamber-2 (11) and its adjustable diameter (U form) enable the air to rotate 180 degrees and after the rotation, the suspended particles accelerated by reducing the speed of the air to hit the U-formed base and walls (the air accelerates in the diameter channel, narrowing towards gravity and slightly decelerates in the channel expanding 180 degrees in the opposite direction.) In the meantime, the small particles hanged in the accelerated air adhere and hold on to the surface-2 (12) at the bottom of the air chamber-2 (11) by means of the gravity. The particles adhere on the surface-2 (12) thanks to its structural properties. The said surface-2 (12) has a lubricated or gel structure. Additionally, it contains disinfectant chemicals in its structure. This allows the neutralization of the pathogens.

[0047] The flow rate of the air in the air chamber-1 (3) and air chamber-2 (11) can be adjusted and controlled by the controller unit (1). Controller unit (1) enables the opening and closing of the system. The necessary controls and adjustments can also be performed via the mobile application to be installed on the mobile device. Battery status of the invention, remaining charge, led-1 (8) and led-2 (9) can also be controlled through the controller unit (1). Additionally, the air flow rate can be controlled via control switches (2).

[0048] The flow of air in the air chamber-2 (11) rotates in the air channels (20) at least 3 times by means of the controller unit (1). The air inside the air chamber-2 (11) is exposed to UVC-radiation by at least one led-2 (9) located on the inner wall of the air channel (20) before arriving the outlet port-2 (21). Led-2 (9) has UVC (Ultraviolet C) properties and provides UVC-radiation. The air is disinfected by means of UVC-radiation under the led-2 (9). UVC-radiated air is transmitted to outlet port-2 (21). Disinfected and particle-free air is transmitted to the pipe (13) through outlet port-2 (21). Inner wall of the pipe (13) has a smooth, soft and kink-prevented structure. The air passed through the pipe (13) is transmitted to the junction point (14). The junction point (14) transfers the filtered clean air to the junction point-2 (18).

[0049] Air transferred to the junction point-2 (18) is then delivered to at least one supply canal (15) located in the helmet. The supply canal (15) provides the distribution and transmission of the air, forming an air curtain thuswise. The air is then transferred to the visor (16) by means of air blow nozzle(s) (19). The air blow nozzle (19) provides the formation of air curtain and the air flow ensures one-way air release. The air blow nozzle(s) (19) also prevents fogging on the goggles with its one-way air flow in cases when protective glasses are worn and filters the inhaled air thuswise. The air conveyed to the veiled visor (16) is collected clean and pathogen-free. Visor (16) structure ensures the clean air to form an air curtain in the visor (16).

[0050] The inventive protective visored (16) helmet with disinfected air flow property is used by means of an adjustable helmet band (17).

[0051] The HEPA filter (6) can be changed by opening the cover screw (4), which can be manually opened, located at the bottom of the air chamber-1 (3).
