Description

LIGHT ACTIVATED SELF-CLEANING FACE MASK, MATERIALS AND THEIR
USAGE AREAS
Technical Field of the Invention
The invention relates to cartridges with self-cleaning filter properties with the help of photocatalytic oxidation mechanism and the systems containing these cartridges in order to destroy organic and inorganic dirt and microorganism load accumulated on disposable surgical masks used in laboratories and hospitals, masks used in daily life during epidemic periods and other materials.
Known State of the Invention-Related Technique (Prior Art)
Surgical masks are designed for single use only for a certain group of users, and they complete their lifespans after certain time period depending on the filtration properties and the environment in which they are used, and then they are disposed of. In addition, masks should not be touched while putting it on and taking it off or while wearing it. Those who do not aware of these proper methods may cause more harm than good to themselves.
Even if the masks have not completed their life span, the breath exhaled when used for a long time also accumulates moisture and creates a suitable environment for bacterial growth on the inner surface of the mask. Even if this situation does not cause an infection, it can create a bad odor and disturb the user.
Moreover, a large number of masks per day are required for each user due to the short life span of disposable masks, and this causes severe effects on the environment.
After the discovery of the photocatalytic property of titanium dioxide (T1O2) in 1972 by Fujishima and Honda (Fujishima & Honda, 1972), the photocatalytic properties of many semiconductor metal oxides have been widely investigated. Semiconductors such as T1O2, ZnO, SnCE, CuO, WO3, Fe203 have been of great interest due to their unique properties such as low toxicity, low cost, photochemical stability (Arora, Jaswal, Singh, & Singh, 2016; Ray & Pal, 2017; Sudha & Sivakumar, 2015). Among these semiconductors, titanium dioxide, which exhibits high photocatalytic activity under UV light, is one of the most suitable semiconductors for environmental applications such as water disinfection, air cleaning and decontamination of harmful waste. For this reason, titanium dioxide is frequently used in surface coatings. When titanium dioxide is exposed to UV light, it can be used in purifying water, obtaining self-cleaning, non-fogging surfaces and cleaning the air. When titanium dioxide absorbs UV light, a chain of reactions starts leading to the generation of radicals. These radicals cause organic materials to decompose by oxidation mechanism. With the help of this phenomena, when coatings containing titanium dioxide exposed to UV-light, it causes bacteria, algae and fungi to break down.
Self-cleaning, antimicrobial surfaces were obtained with the coatings prepared by taking advantage of the photocatalytic properties of titanium dioxide in patents numbered US7541509, US2011024557 and US20200318283. However, titanium dioxide can only be activated by UV light exposition and since UV light makes up only a small fraction of the solar spectrum, the use of titanium dioxide in practical applications is limited.
Similarly, in patents CN101912167A and CN204763024U, surface of disposable masks are incorporated with titanium dioxide, but the performance of the surfactant may change in environments without UV light.
For these reasons, there is a need for self-cleaning, reusable masks even in environments without UV light.
Brief Description of the Invention
With this invention, the system and the components of this system are described, by proposing a reusable and self-cleaning mask to be used instead of disposable surgical masks, by using light to remove the potentially accumulated organic molecules and microorganism load on the mask during use.
The invention system consists of; a mask body, headbands, a replaceable cartridge which includes a filter-featured fabric with photocatalytic particles (such as titanium dioxide and similar metal oxides) coted on its surface, the battery slot, the 395 nm UV LED electronic circuit, charging unit and circuit cover.
In the system, the organic molecule and microorganism load accumulated on the permeable surface of the mask is broken down into water and carbon dioxide with free radicals created on the active fabric by UV (300-400 nm) light exposition. By this process, the surface is continuously decontaminated from microbial loads such as spore, pollen, bacteria, mold, fungus and protein loads such as nucleic acid smeared on the surface. With the UV LEDs located on the mask, decontamination is carried out independently from daylight and therefore performance losses that may occur due to insufficient UV light in indoor places are eliminated.
The inventive masks use much less fabric than normally used in masks, consequently they create much less waste than normally caused by other face masks. Also, the risk of disease transmission that this type of waste may create on other individuals and the environment is also eliminated.
This type of mask designs in cartridge form also provide other advantages for the users in terms of cost. After purchasing the mask once, the user will be able to supply the different fabrics as consumables to be used in the cartridge.
Furthermore, by adding different types of refreshing or therapeutic scent molecules to the fabric, additional advantage can be provided to the users.

Detailed Description of the Invention:
In this detailed description, the system containing a mask that cleans itself with light is explained only for a better understanding of the subject and without any restrictive effect.
Invention (the system with light activated self-cleaning mask) comprises; a) The replaceable cartridge (2), which is located on the mask body (4) and comprising surface active fabric (9) coated with particles showing photocatalytic properties, b) At least one UV LED (7) located on the body of the mask (4), which enables the surface active fabric (9) to be cleaned by scattering light on the cartridge body (10)
The basic elements of the system forming the invention are shown in Figure 1. The system comprises the mask (1) and the cartridge (2) with replaceable particle filter, at least one UV LED (7) positioned on the mask and the headband (3).
As shown in Figure 2, the mask (1) comprises the head band (3) placed on the mask body (4), the on / off button (5), the electronic circuits, the charging unit and the battery compartment (6) that contains the battery.
The replaceable cartridge (2) shown in Figure 3 includes a surface active fabric (9) placed between the cartridge cover (8) and the cartridge body (10). The surface active fabric (9) comprises 97% polyester and 3% pure silver. Bacteria filtration efficiency is > 98%.
The surface of the surface- active fiber is coated with photocatalytic particles such as titanium dioxide, zinc oxide and/or silver nanoparticles. Surface can be coated with one or more photocatalytic particle.
UV LED (7), which is powered by the batteries housed in the battery compartment (6), causes the titanium dioxide coated surface-active fiber to produce free radicals by illuminating the surfaceactive fabric (9) in the replaceable cartridge and these free radicals break up the organic/inorganic dirt, biological molecules such as proteins and microbial/viral load accumulated on the surface-active fiber.
The apparatus (11) which can be worn on any type of single-use mask is illustrated on Figure 4. This apparatus is also powered by battery and by the means of UV-LED light, can exterminate biological agents and organic/inorganic loads accumulated on the replaceable surface-active material.
Method of production and usage of the mask is given below.
Mask body (4), is produced from medical class acrylonitrile butadiene styrene (ABS), polyethylene (PE) or polypropylene (PP), etc. material and will be waterproof with its surface quality. Mask body (4), which holds together the entire device, is fixed on the face via head bands (can be elastic if required) and turned on by the on/off button (5) on the battery housing and causes the UV LED (7) to illuminate the cartridge body (10). Light illuminates the cartridge body (10) causes the extermination (decontamination) of every type of viable or nonviable biological structure and organic/inorganic dirt on the surface of the surface-active fabric (9) by the photocatalytic oxidation on the fiber surface. Therefore, it facilitates the mask user to be effectively protected from viruses in the air or contact transmissible-viruses, especially in periods such as the ongoing COVID19 pandemic.
The cartridge is designed to be replaceable if the cartridge needs to be replaced due to physical impact due to dropping, etc or an irremovable stain on the cartridge. At the same time, this situation allows the design and use of cartridges with different properties on the same body. Body is going to be in a format which facilitates the use of children and which attracts the children (with cute animal faces or funny faces). Furthermore, body is going to be designed in a way that it can accommodate colors of different teams (such as yellow-navy, yellow-red, black- white). Moreover, it is going to be customizable for different brands (such as aviation firms). In addition, due to the composite structure which will be formed by adding antimicrobial particles such as silver and zinc oxide into the body, advanced hygiene can be achieved by preventing the contamination that may occur on the body. In addition, masks and cartridges with different structures can be designed for different areas of use. For example, the battery compartment (6) can be designed to be mounted directly on the cartridge from the inside. Additional comfort and protection can be provided to the user by absorbing pleasant scent and/or therapeutic molecules on the surface-active fabric (9). In another design (Figure-4), light-emitting LEDs (7) are sewn on the apparatus which can be mounted on the mask (11) and are attached on a mask made of surface-active material (12) in a way to reflect light. LED lights are turned on with a battery group when desired. The free radicals that will form on the surface coated with titanium dioxide or metal oxide or other catalysts that have photocatalytic oxidation ability when the surface-active material (12) is exposed to UV-A band (such as 395nm) or when sunlight hits the surface, will oxidize and exterminate all kinds of biological agents (such as spores, bacteria, viruses, molds, fungi, pollens and biological molecules) and organic/inorganic molecules and odorous molecules adsorbed on the surface. In this way, no pathogenic organism will remain on the surface and the safety of the person using the mask will be ensured and spreading of the contaminants that may occur on the mask to the environment and other people / animals will be prevented. For this reason, masks made of active fabric or surface-active materials (for example, textiles) and designed for single use are both safer and can be used multiple times. In addition, the apparatus (11) that can be worn on the mask, the surface-active material (12) and the battery group (6) are detachable from each other and can be used together or separately. When necessary, the apparatus (11) can be used again by changing only the surface- active material. Alternatively, the apparatus (11) and battery group (6) can be mounted on a mask made of surface-active material and can be used independently.
This type of LED (7) strings strung on a cable can be also be used to effectively purify materials produced from materials coated with surface- active materials such as medical overalls, aprons, caps, protective glasses in addition to masks produced from surface-active material (12) from biological agents. In this way, the spread of biological agents contaminating the overalls of the staff working in places with biohazard risk to other places will be prevented in a practical and cost-effective way.
