Description

Mask with antifungal and antiviral function}

The present invention relates to an antibacterial and antiviral mask.

Recently, masks have become a necessity that must be worn during outdoor activities. When the mask is worn for a long time, there is a problem in that bacteria grow enormously inside the mask due to moisture generated during the breathing process.

Accordingly, various types of masks having an antibacterial effect have been proposed.

KR 20-0474665 proposes a mask equipped with an antibacterial member containing a liquid phytoncide extract having an antibacterial effect, and in KR 20-0460479, silver yarn is mixed with antibacterial cellulose fibers to remove bacteria and viruses. A mask with an antibacterial sheet inserted inside is proposed. However, even if such a mask is used, if it is worn for a long time, the humidity or temperature of the inner space of the mask gradually increases, and the generation of bacteria due to moisture cannot be avoided.

Accordingly, for the purpose of lowering the humidity and temperature of the internal space, KR No. 10-2019-0025468 discloses a mask equipped with a fan, and KR No. 10-1942785 discloses a mask equipped with an outlet and an inlet. There is a drawback of high production cost.

Moisture generated when wearing a conventional mask has a problem of generating bacteria and has become an object that must be removed.

The present invention completely reversed this concept and produced a new concept of a mask capable of securing an antiviral effect as well as an antibacterial effect by using the moisture inside the mask.

KR 20-0474665 B1 (2014.09.26) KR 20-0460479 B1 (2012.05.15) KR 10-1942785 B1 (2019.01.22) KR 10-2019-0025468 A (2019.03.11)

The present inventors have developed a mask having an antibacterial and antiviral effect by generating a microcurrent by using moisture due to moisture in the mask as an electrolyte.

Currently, a field using microcurrent is applied to a medical field such as pain treatment, a cosmetic device field such as skin care, or a hair loss device, but not much has been applied to a mask like the present invention.

Accordingly, an object of the present invention is to provide a mask having antibacterial and antiviral effects.

In order to achieve the above object, the present invention is to have an antibacterial and antiviral effect by generating a microcurrent, a mask body; And it provides an antibacterial and antiviral mask provided with a fixing member capable of fixing the mask body to the face at both ends thereof.

In this case, the mask body includes at least one of an inner skin and an outer skin, and includes a fine current generator for generating a fine current while the mask is mounted.

Specifically, the mask body has a structure including a current generating portion positioned between the inner skin and the outer skin, or a structure in which the current generating portion is positioned on either the inner skin and the outer skin.

In addition, triboelectricity is generated between the inner or outer skin and the current generating unit due to mutual friction between them.

The minute current generator is a single sheet formed so that the first metal pattern and the second metal pattern do not overlap on the support.

In addition, the minute current generator is a double sheet including a first sheet having a first metal pattern formed on the first support and a second sheet having a second metal pattern formed on the second support.

The mask according to the present invention focuses on the idea of using moisture in the mask, which has been a problem in the past, and proposes a new concept of a mask.

This mask can secure antibacterial and antiviral effects by microcurrent, and can effectively suppress the growth of bacteria or viruses in the mask even when used for a long time, and has an effect of reducing fine dust.

In addition, due to the water-repellent and oil-repellent coating layer formed on the outer skin, moisture does not permeate, so it exhibits a splash blocking effect, and as the time remaining in the microcurrent generator increases, not only the generation time of the microcurrent is shortened, but the duration is also extended. There is an advantage to be able to.

Such a mask can be manufactured at low cost, and can play a leading role in the field of electroceuticals in which electronic and pharmaceuticals are recently known.

The mask according to the present invention has antibacterial and antiviral effects by micro-current.

The microcurrent is a current that falls within the range of several to hundreds of microamperes (㎂), and can be generally referred to as sub-sensory level stimulation. Stimulation by such a microcurrent can be distinguished from other forms of electrical stimulation because the intensity of the current is much lower than that of a form such as transcutaneous electrical nerve stimulation. In addition, in the present invention, the minute current is not generated by an external current supply device, but is generated by metals having different electrical characteristics such as a potential difference, so that continuous and almost uniform supply of minute current can be realized.

The microcurrent generated through the mask of the present invention is

Focusing on the structure of a galvanic cell, the positive and negative electrodes induce the generation of microcurrent due to the redox reaction due to the electric potential difference in the presence of moisture.

In addition, in order to induce the generation of static electricity, the generation of static electricity is induced by frictional electricity generated by mutual friction by using fibers of different polarities. At this time, triboelectricity has the effect of adsorbing fine dust.

Hereinafter, a method according to each method will be described.

In the generation of a microcurrent due to a potential difference, a spontaneous reaction occurs in which two types of electrodes with different ionization tendencies are redoxed in an aqueous solution, and electrons move through this spontaneous reaction to generate a microcurrent.

The known zinc-silver galvanic battery undergoes the following battery chemistry.

Eo = +0.80 V Ag ⁺ (aq) + e ^-1 ---> Ag(s) reduction

Eo = -0.76 V Zn ²⁺ (aq) + 2e ^-1 ---> Zn(s) oxidation

Ecell = +1.56 V 2 Ag ⁺ (aq) + Zn(s) ----> 2Ag(s) + Zn ²⁺ (aq)

According to the above equation, Zn that has lost electrons while emitting electrons is ionized (positive ion) to Zn2+, and Ag that has obtained electrons becomes positive electrode (+), and a minute current is generated in this process.

Electrochemical reactions tend to lose electrons and become positive ions (oxidation) as the tendency of ionization increases. When Zn and Ag are combined as follows, Zn becomes the positive electrode and Ag becomes the negative electrode. However, when Ag and Au are combined, the anode becomes Ag and the cathode becomes Au.

(Ionization tendency)

K> Ca> Na> Mg> Al> Zn> Fe> Ni> Sn> Pb> H> Cu> Hg> Ag> Pt> Au

The galvanic battery is caused by the potential difference between two types of metals, and even the same metal can be a positive electrode or a negative electrode. At this time, the microcurrent generated when a metal having a large difference in ionization tendency is combined (ie, the greater the potential difference) Become stronger.

Meanwhile, the generation of static electricity by triboelectricity is caused by the movement of (+) and (-) electric charges that occur when two different objects are rubbed.

In other words, triboelectricity is a phenomenon caused by frictional energy generated between two substances. When two objects come into contact with or separate from each other, electric charges move at the interface, resulting in the same amount of excess (+) charge and Excess (-) charge, that is, static electricity is generated, and the static electricity has the effect of adsorbing fine dust.

Objects that can generate static electricity are not unconditionally charged with positive (+) or negative (-) charges, but depend on which ones are more prone to positive (+) and which ones are more prone to negative (-). It is selected in consideration of the material (ie, triboelectric series) of the charging characteristics of the electric charge.

For example, nylon, polyurethane, and the like are most heavily charged with a (+) charge, and Teflon and silicone rubber are most heavily charged with a (-) charge. Based on this tendency, the material of the constituent elements constituting the mask can be selected.

The microcurrent generated by the above-mentioned potential difference impairs the electrostatic force required when the strain or virus binds to the human body, thereby giving the function of killing the virus or losing the infectious power, and the triboelectric effect reduces fine dust by generating static electricity. At the same time.

In order to induce the potential difference and triboelectricity, in the present invention, a mask having a new structure is designed, and components in each layer and their shape are defined.

The fixing member 2 may be selected from, for example, a detachable/detachable band that is detachable and attached by winding the back of the head. In addition, the fixing member 2 may have an elastic force as well known.

If necessary, the mask may further include a wire band 3 on the upper side of the mask body 1 so that the mask may more closely adhere to the face according to the shape of the nose.

When the wearer breathes, moisture is generated by moisture generated in the nose and mouth, so it becomes easily moist when used for a long time, which can become a hotbed for the occurrence of various bacteria and viruses.

Accordingly, as shown in FIG. 1 between the inner skin 11 and the outer skin 15 of the present invention, a microcurrent generator 13 made of two sheets is positioned, and the moisture acts as an electrolyte to generate a microcurrent. , Antibacterial and antiviral effects are secured by the generated microcurrent, thereby enabling the wearing of a mask in a comfortable state, and an effect of removing fine dust by triboelectricity generated at this time can be additionally secured.

The minute current generator 13 has a structure in which a metal pattern is formed on a support to generate a potential difference and triboelectricity.

2A and 2B are views for explaining the microcurrent generator 13 of a single sheet structure according to an embodiment of the present invention, and a first metal pattern 25a on the support 23a And a second metal pattern 27a formed thereon.

Can be The combination of this metal material has an advantage that it has a high potential difference, and it is possible to more easily generate a minute current.

In the mask provided with the micro-current generator 13 of FIG. 2, moisture generated by the wearer's breath, that is, moisture acts as an electrolyte, and the first and second metal patterns 25a and 27a are respectively positive and negative. And generates a micro current due to the potential difference. The microcurrent generated by the potential difference serves to destroy the electrostatic force required when the strain or virus in the mask body 1 binds to the human body, thereby killing the virus or losing the infectivity.

Meanwhile, in addition to the method of forming two types of metal patterns on one support as shown in FIG. 2, a method of forming metal patterns on each support is possible.

3 is a view for explaining a fine current generator 13 of a double sheet structure according to another embodiment of the present invention. In the case of adopting a double sheet structure, there is an advantage in that it is possible to additionally secure the generation of static electricity due to triboelectricity in addition to microcurrent due to a potential difference.

Specifically, the first sheet 13b of the microcurrent generator 13 has a first metal pattern 27b formed on the first support 25b, and the second sheet 13c is a second support 25c. It has a structure in which a second metal pattern 27c is formed thereon.

The first support 25b and the second support 25c may be of the same or different materials, and cotton, non-woven fabric, polyester, polypropylene, nylon, polyurethane, etc. used in the inner skin 11 and the outer skin 15 It may be a synthetic fiber.

The first metal pattern 27b and the second metal pattern 27c may have a potential difference and may be different metals so as to generate static electricity by friction. Al, Zn, Fe, Ni, Sn, Cu, Hg, Ag , Pt, Au, and one selected from among their alloys is possible.

The metal pattern represented by the first metal pattern 27b and the second metal pattern 27c means a pattern in which figure patterns having a certain area are arranged in a spaced apart form, and the pattern shape is a parallel pattern or a series pattern. It may include, and by adjusting the pattern-shaped figure pattern it is possible to set the generation area of the minute current.

The metal pattern usually includes a single rectangular, circular, or hemispherical plate, but one or more hemispherical plates form various figure patterns, so that a minute current can be uniformly generated.

According to one embodiment, the first metal pattern 27b may be a circular pattern made of silver (Ag), and at this time, the thickness may be 0.001 to 0.5 mm, and the diameter may be 1.0 to 2.5 mm, and between them is 0.5 To form an interval of 1.0mm. In addition, the second metal pattern 27c may be a circular pattern made of zinc (Zn), and at this time, the thickness may be 0.001 to 0.5 mm, and the diameter may be 0.5 to 1.0 mm, and between them is 0.1 to 1.0 mm. Formed at intervals.

In particular, the first metal pattern 27b and the second metal pattern 27c are arranged in a zigzag manner so that the two patterns 27b and 27c do not overlap when they are laminated to the mask body 1.

Formation of the first metal pattern 27b and the second metal pattern 27c is performed by a wet method such as rotary roll-to-roll printing, screen printing, transfer gravure printing, or deposition such as sputtering on each of the supports 25b and 25c. Dry method can be used. For example, the first metal pattern 27b made of Ag is performed by combining roll-to-roll printing and gravure printing using silver paste, and in the case of the second metal pattern 27c made of Zn, roll-to-roll printing and screen printing are performed. It is performed in combination. In this case, different printing methods are applied depending on the type of material forming the metal pattern.

4 is a schematic diagram for explaining a driving principle of a mask according to an embodiment of the present invention. At this time, it is shown exaggerated to explain the thickness of each layer, and in actual production, the thickness of each layer can be differently manufactured. At this time, the mask has a structure in which the endothelium 11 is excluded, and if necessary, the endothelium 11 can be added.

Referring to FIG. 4, moisture, that is, moisture, exists in the microcurrent generator 13, which is an inner region of the mask body 11, by the user's breath. This moisture acts as an electrolyte, whereby the first and second metal patterns 27b and 27c formed in the first sheet 13b and the second sheet 13c act as anodes and cathodes, respectively, and microcurrents due to potential difference Occurs. The microcurrent generated by the potential difference exists in the space between the first sheet 13b, the second sheet 13c, and the outer shell 15, and the electrostatic force required when the strain or virus between them binds to the human body By damaging the virus, it kills the virus or loses its infectious power.

In addition, by the user's breathing (arrows in Fig. 3, that is, inhalation and exhalation), the microcurrent generation unit 13c and the outer skin 15 move to each other, so that the first sheet 15 and the second sheet 13c or the second sheet 2 As friction with the metal pattern 25c occurs, static electricity due to triboelectricity is generated. Static electricity caused by triboelectricity is generated between the second sheet 13c and the outer shell 15, as shown in FIG. 4, and this has an effect of adsorbing fine dust by static electricity.

With regard to the generation of static electricity by triboelectricity, the spacing of these materials is controlled so that as much as possible, together with the selection of the most suitable material for obtaining triboelectricity.

Preferably, the first sheet 13b is a cooling fiber, the second sheet 13c is a non-woven fabric, and the outer shell 15 may be a porous urethane-based sponge. The first sheet 13b has an effect of imparting a refreshing sensation due to the cooling sensation fiber, preventing contamination of cosmetics to the mask, and suppressing skin troubles. The second sheet 13c is made of different materials to have triboelectricity with the outer shell 15, but as described above, the second sheet 13c is a nonwoven fabric such as polyester or polypropylene, and the outer shell 15 Urethane-based materials can be used.

At this time, the first sheet 13b and the second sheet 13c are spaced in a range of 0.1 to 1.5 mm.

5 is a schematic diagram for explaining a driving principle of a mask according to another embodiment of the present invention, and is a structure in which an endothelium 11 is added to the mask.

In the mask of this structure, in addition to the triboelectricity between the galvanic cell of the microcurrent generator 13 and the outer shell 15, triboelectricity between the inner skin 11 and the microcurrent generator 13 is further generated, thereby reducing the intensity of the microcurrent. There is an advantage that it can be increased.

In this case, the material of the inner skin 11 may be used as a cooling fiber or the like as described above, or a non-woven material such as polyester or polypropylene.

Another explanation follows what was mentioned in FIG. 4 above.

Meanwhile, although not shown, the microcurrent generating unit 13 may be formed on at least one of the inner skin 11 and the outer skin 15. At this time, the mask body 1 may be a single structure in which the micro-current generator 13 is formed on the outer skin 15 without the inner skin 11, or the inner skin 11/shell 15 in which the micro-current generator 13 is formed. ), or the structure of the outer shell 15 in which the inner skin 11 / micro current generator 13 is formed.

If necessary, at least one of the inner skin 11 and the outer skin 15 of the present invention is coated to show water repellency/oil repellency/antibacterial/splash blocking performance, and more preferably, a coating is applied to the outer skin 15. Done. When formed on the outer shell 15 side, contamination from the outside can be prevented and moisture can be more retained in the micro-current generator 13, thereby further increasing the intensity of the micro-current generation.

Water repellency is a property that repels water or does not show affinity for water, and oil repellency is a property that repels oil or does not show affinity for oil. If it has water repellency/oil repellency at the same time, the contact angle between water and oil is high, so when it comes into contact with them, repulsive force is generated and it bounces to the outside.

When the inner skin 11 and the outer skin 15 have water repellency and oil repellency, moisture does not permeate to block droplets, and as the time remaining in the micro current generator increases, the generation time of micro current is shortened. It also has the advantage of extending the duration.

In this way, the endothelium 11 on which the coating layer having water repellency/oil repellency is formed can prevent excessive moisture adsorption to prevent moisture during use, thereby reducing discomfort and preventing the growth of bacteria. In addition, the outer shell 15 blocks contaminants from the outside to prevent contamination of the microcurrent generator 13. Such contamination causes deterioration of the function of the electrode pattern, thereby reducing the generation of microcurrents, so that sufficient antibacterial and antiviral effects cannot be secured.

This effect can be secured when the coating layer is used in an amount of 0.01 to 10 parts by weight, preferably 0.5 to 7 parts by weight, based on 100 parts by weight of the inner skin 11 or the outer skin 15.

In addition, it is possible to secure a pleasant functional cooling effect by having a function of blocking UV rays and absorbing sweat as well as blocking droplets and fine dust. In addition, it has excellent breathability and elasticity, and if it is manufactured with a very thin (about 1mm) thickness, it gives a feeling of not wearing it, so it can be worn during exercise.

The manufacturing method of the mask according to the present invention can be manufactured by using a known method as it is or by applying it.

According to one embodiment, the fine current generator 13 is manufactured by cutting so as to be laminated with the inner skin 11 and the outer skin 15 of the mask. Cutting is performed using a conventional cutting machine. In this case, when a hole is formed in the minute current generator 13, it may be performed before or after the cutting process.

In the manufacture of the mask according to the present invention, the inner skin 11, the outer skin 15, and the microcurrent generating unit 13 are each manufactured, and then, the mask is manufactured by combining them. In this case, the combination method uses a method such as a solid adhesive, a liquid adhesive, a sewing, or a bonding means such as heat or ultrasonic waves, but is not limited thereto.

The mask according to the present invention effectively blocks external dust, dust, and bacterial viruses, secures antibacterial and antiviral effects by the generation of microcurrents, and blocks droplets and contaminants from the outside by a water-repellent/oil-repellent coating. Together with preventing excessive moisture adsorption. For this reason, not only a waterproof effect but also a deodorizing function can be expressed.
