Description

Wet smoke mask capable of generating oxygen

[0001] The present invention relates to a smoke mask capable of blocking smoke generated at a fire scene and supplying oxygen, and more particularly, to a wet smoke mask capable of generating oxygen, which safely protects the respiratory organs of a wearer from smoke generated at a fire scene and supplies oxygen, by unfolding a smoke mask provided in a folded state when a fire occurs, so that a region of a reaction liquid supply portion of an oxygen generating unit provided inside the smoke mask is torn, causing a reaction liquid to be discharged and delivered to an oxygen generating member, and the delivered reaction liquid and the oxygen generating member react to generate oxygen, thereby helping the wearer breathe smoothly.

[0002] In general, the primary cause of death in fires is asphyxiation from toxic gases. Therefore, gas masks and smoke respirators are provided for use in enclosed spaces, indoor spaces, and underground areas to protect people from toxic gases, smoke, and other hazardous substances generated by accidents or fires.

[0003] However, gas masks are expensive for the general public to use, and the time it takes to put them on and the method of putting them on in the event of a fire are complicated and difficult, so it may take a long time for someone wearing a gas mask for the first time to put it on, and even if they know how to put it on, they may not be able to put it on quickly in an emergency, and there is a risk of being exposed to toxic gases and smoke from the fire while putting it on.

[0004] In an effort to solve the above problem, Korean Patent No. 10-2393243 discloses a technology for a disaster evacuation and fine dust mask, which can block the inflow of smoke and toxic gases generated in a fire and fine dust such as dust generated at industrial sites, and can discharge carbon dioxide emitted by the wearer's breathing to the outside, and secure a field of vision from smoke, toxic gases, and dust during fire evacuation and industrial site work.

[0005] However, in the case of the above-described prior art, there is a problem that the supply of oxygen is not smooth because it only includes a guide tube for simply discharging carbon dioxide emitted by the wearer's breathing to the outside and a check valve for preventing the inflow of external smoke, toxic gases, and fine dust, and it is not easy to wear because the guide tube is positioned so that the wearer's mouth is received, and then the ear band formed on the mask is hung on the ear.

[0006] The present invention was created to solve the above problems, and the purpose of the present invention is to provide a wet smoke mask capable of generating oxygen, which safely protects the respiratory organs of the wearer from smoke generated in the event of a fire by unfolding the smoke mask provided in a folded state, so that an area of ​​the reaction liquid supply portion of the oxygen generating portion provided inside the smoke mask is torn, the reaction liquid is discharged and delivered to the oxygen generating member, and the delivered reaction liquid reacts with the oxygen generating member to generate oxygen, thereby supplying oxygen to help the wearer breathe smoothly.

[0007] In order to achieve the above object, according to one embodiment of the present invention, a wet smoke mask capable of generating oxygen comprises: a mask body formed in a form folded in half and formed in a form that simultaneously shields the mouth and nose of a wearer when unfolded; an exhaust valve installed in an area of ​​an outer surface of the mask body and having an exhaust port formed so that the wearer's exhaled breath can be discharged to the outside; a filter unit formed on the inside of the mask body; and an oxygen generating unit installed on an outer surface of the filter unit positioned adjacent to the wearer's face and supplying oxygen generated as the mask body is unfolded to the wearer; wherein the oxygen generating unit comprises: a Tyvek filter formed in a size corresponding to a size of the filter unit; a reaction solution supply unit positioned within the Tyvek filter and composed of a vinyl bag containing a reaction solution and porous fibers wrapping the vinyl bag; And an oxygen generating member comprising an oxygen generating compound that receives the reaction liquid supplied from the reaction liquid supply unit and causes a chemical reaction to generate oxygen; characterized in that, as the mask body is unfolded, one area of ​​the vinyl pack of the reaction liquid supply unit is torn and the reaction liquid is supplied to the oxygen generating member to generate oxygen.

[0008] The above oxygen generating unit is preferably formed in a form folded in half with respect to the central axis so that it unfolds together with the mask body formed in a form folded in half.

[0009] The vinyl pack of the reaction solution supply unit preferably has a reaction solution receiving space formed in one area where the reaction solution is received, and a horizontal cut groove formed in one area of ​​a side of the reaction solution receiving space, wherein one end of the vinyl pack where the reaction solution receiving space is located is fixed to the rear surface of the porous fiber, one area of ​​the upper and lower portions of the other end of the vinyl pack where the cut groove is formed is fixed to one end of the vinyl pack, and an area of ​​the upper and lower portions of the other end of the vinyl pack that is not fixed to one end of the vinyl pack is preferably fixed to the rear surface of the porous fiber.

[0010] It is preferable that the reaction solution supply unit is configured such that when the mask body is unfolded, the vinyl pack of the reaction solution supply unit is unfolded, the cut groove formed in the vinyl pack is torn, and the reaction solution contained in the reaction solution receiving space is discharged, so that the porous fiber surrounding the vinyl pack carries the reaction solution, thereby continuously supplying the reaction solution to the oxygen generating member.

[0011] The above oxygen generating compound is preferably formed by mixing an oxidizing agent including at least one of potassium superoxide and sodium peroxide, a stabilizer including at least one or two or more of calcium hydroxide, aluminum hydroxide and magnesium hydroxide, and silica gel and carrageenan in a preset ratio.

[0012] The exhaust valve preferably includes a lower housing formed at a location corresponding to one of the positions of the mouth and nose of the wearer among the areas of the mask body, and having a first exhaust port penetrating the mask body formed in one area of ​​the lower portion; a valve formed larger than the first exhaust port and having a hole formed in one area of ​​the upper portion, and the hole being inserted and fixed into a fixing portion protruding in one area of ​​the lower housing to block the first exhaust port, and an area excluding the fixed area being movable according to the wearer's breathing; and an upper housing coupled to the lower housing, and having a second exhaust port formed in one area of ​​both sides and one area of ​​the lower portion so that the wearer's exhaled breath is discharged to the outside.

[0013] The lower housing is preferably formed with a protrusion and a joining groove along the outer surface of the lower housing, and the upper housing is preferably formed with a joining protrusion that is inserted into the joining groove at the lower end of the upper housing, and after fixing the valve to the fixing portion of the lower housing, the joining protrusion of the upper housing is inserted into the joining groove of the lower housing to form the exhaust valve.

[0014] The mask body is preferably formed of a flame-retardant non-woven material, and the filter section is formed with a plurality of filters on the inside of the mask body, and an exhaust valve hole communicating with the exhaust valve is formed in each of the plurality of filters.

[0016] It is preferable that the above mask body further include a silicone part that is installed along the inner edge of the mask body and adheres closely to the wearer's skin when worn to block outside air.

[0017] The wet smoke mask capable of generating oxygen according to the present invention has the effect of safely protecting the respiratory organs of the wearer from smoke generated in the event of a fire by supplying oxygen, while at the same time helping the wearer breathe smoothly, by unfolding the smoke mask provided in a folded state, tearing an area of ​​the reaction liquid supply portion of the oxygen generating unit provided inside the smoke mask, causing the reaction liquid to be discharged and transferred to the oxygen generating member, and generating oxygen through a reaction between the transferred reaction liquid and the oxygen generating member.

[0018] In addition, according to one embodiment of the present invention, oxygen can be generated from an oxygen generating unit provided inside the smoke mask simply by unfolding the smoke mask provided in a folded state, thereby enabling rapid use in an emergency situation.

[0019] In addition, according to one embodiment of the present invention, the oxygen generating unit is formed of a Tyvek filter made of Tyvek material, thereby preventing leakage of the reaction liquid from the reaction liquid supply unit introduced into the Tyvek filter, thereby allowing the wearer to receive only the oxygen generated from the oxygen generating unit, thereby creating a comfortable breathing environment.

[0020] In addition, according to one embodiment of the present invention, by including silica gel and carrageenan, which have excellent moisture absorption properties, in addition to an oxidizing agent and a stabilizer, in the oxygen generating compound constituting the oxygen generating member, moisture generated during the oxygen generating process of the oxygen generating compound is absorbed, thereby preventing low-temperature burns caused by moisture generated during the oxygen generating process of the oxygen generating compound.

[0030] The present invention relates to a smoke mask capable of blocking smoke generated at a fire scene and supplying oxygen, and more specifically, to a wet smoke mask capable of generating oxygen, which safely protects the respiratory organs of a wearer from smoke generated at a fire scene and supplies oxygen, by unfolding a smoke mask provided in a folded state when a fire occurs, so that a region of a reaction liquid supply portion of an oxygen generating unit provided inside the smoke mask is torn, so that a reaction liquid is discharged and delivered to an oxygen generating member, and the delivered reaction liquid reacts with the oxygen generating member to generate oxygen, thereby helping the wearer breathe smoothly.

[0031] For a more specific explanation, the present invention will be described below with reference to the attached drawings, and multiple drawings may be referenced simultaneously to explain one technical feature and component constituting the invention.

[0032] Meanwhile, in the following description, some of the components described in the drawings are omitted or excessively enlarged or reduced in order to explain the functions of each component of the present invention, but it will be understood that the depicted details do not limit the technical features and scope of rights of the present invention.

[0033] Additionally, in the following description, multiple drawings will be simultaneously referenced and described to explain one technical feature or component constituting the invention.

[0034] Looking briefly at the drawings attached as a description of the present invention, FIGS. 1 to 3 illustrate examples of the schematic shape of a wet smoke mask capable of generating oxygen according to an embodiment of the present invention, and FIG. 4 illustrates an example of the schematic shape of an exhaust valve according to an embodiment of the present invention. In addition, FIG. 5 illustrates an example of combining a filter unit and an oxygen generating unit to a mask body according to an embodiment of the present invention, and FIGS. 6 and 7 illustrate examples of the schematic shape of an oxygen generating unit according to an embodiment of the present invention.

[0035] Referring to FIGS. 1 to 3, which illustrate examples of a schematic shape of a wet smoke mask capable of generating oxygen according to an embodiment of the present invention, the wet smoke mask capable of generating oxygen according to the present invention (hereinafter referred to as the 'wet smoke mask of the present invention') is largely composed of a mask body (100), an exhaust valve (200), a filter unit (not shown), and an oxygen generating unit (400).

[0036] First, the mask body (100) described above constitutes the overall exterior of the wet smoke mask of the present invention, and is formed in a form folded in half, but can be formed in a form that simultaneously shields the wearer's mouth and nose when unfolded.

[0037] At this time, it is preferable that the mask body (100) described above be made of a flame-retardant material so that it can function as a smoke mask, and most preferably, it is preferable that it be formed of a flame-retardant non-woven material.

[0038] In addition to the flame-retardant nonwoven fabric described above, it is also possible to use materials such as polyethylene and polypropylene that have excellent heat resistance, chemical resistance, and durability, or aluminum flame-retardant flame-retardant material fabric that is made of aluminum and does not easily catch fire, and the present invention is not limited thereto.

[0039] Meanwhile, in the following description, the mask body (100) described above can be configured to basically include a mask having a shape that is folded in half among all known forms of masks and a known material that can form a mask, and the present invention is not limited thereto.

[0040] Meanwhile, a nose support part (110) formed in a shape corresponding to the bridge of the wearer's nose can be formed on the upper part of the above-described mask body (100), and it is preferable that the above-described nose support part (110) uses a wire whose shape can be changed.

[0041] This can be understood as being for bending the above-described nose support (110) to correspond to the shape of the bridge of the wearer's nose so that the mask body (100) is pressed against the bridge of the wearer's nose.

[0042] Meanwhile, as another embodiment of the present invention, as shown in FIG. 3, the wet smoke mask of the present invention may further include a silicone part (500) that is installed along the inner edge of the mask body (100) described above and adheres closely to the wearer's skin when worn to block outside air.

[0043] At this time, the silicone part (500) described above can function to reliably block external air by closely contacting the wearer's skin when the mask body (100) described above is worn. In addition, it can be understood that the silicone part (500) is formed using an elastic silicone material, so that when the wearer wears the mask body (100), the silicone part (500) adheres to the curves of the wearer's face without lifting, thereby fundamentally blocking external air or external contaminants from flowing in between the mask body (100) and the wearer's face.

[0044] Returning to Fig. 1 and continuing the explanation, a fixing band (120) may be formed on the left and right sides of the above-described mask body (100). The above-described fixing band (120) is a member that enables the above-described mask body (100) to be fixed to the wearer's face, and is preferably formed in a form that hangs on the wearer's ears so that the wearer can easily wear it.

[0045] At this time, the above-described fixed band (120) can be manufactured using a fiber material of elastic material, so that it can be adjusted elastically according to the size of the wearer's head and has the effect of providing a soft wearing feeling.

[0046] In addition, the above-described fixed band (200) may use a band made of elastic rubber material, but in addition to the rubber material band, it may also use a material that is elastic and easy to adjust the length, and the present invention is not limited thereto.

[0047] Meanwhile, although not shown in the attached drawing, as another embodiment of the present invention, the above-described fixed band can perform the function of adjusting the length of the fixed band and improving the wearing comfort through an additional structure such as a hook (not shown), which is performed by positioning the hook on the back of the head of the wearer and fixing the hook to wrap around the head of the wearer by connecting it to the fixed band formed at both ends of the mask body, thereby improving the wearing comfort, and when the smoke mask of the present invention is worn for a long time, it can have the effect of reducing the burden on the ears of the wearer.

[0048] Meanwhile, as an embodiment of the present invention, the fixed band (200) described above in the attached drawing is illustrated as a fixed band (200) that is hung on the wearer's ear, but it is also possible to use a fixed band that surrounds the wearer's head, and the present invention is not limited thereto.

[0049] As another embodiment of the present invention as described above, although not illustrated in the attached drawings, when the above-described fixing band is used as a fixing band (not illustrated) that surrounds the wearer's head, it is possible to form a structure in which the length of the fixing band is adjusted by further including a length adjusting portion (not illustrated). In this case, the above-described length adjusting portion performs the function of finely adjusting the length of the fixing band to match the wearer's head circumference, thereby exerting the effect of more stably fixing the smoke mask of the present invention to the wearer's face.

[0050] Returning to Figure 1 and continuing the explanation, an exhaust valve (200) can be formed in the above-described mask body (100).

[0051] The above-described exhaust valve (200) is installed in an area of ​​the outer surface of the above-described mask body (100), and an exhaust port may be formed so that the wearer's exhaled breath can be discharged to the outside.

[0052] At this time, the exhaust valve (200) described above may include a lower housing (210), a valve (220), and an upper housing (230), as shown in FIG. 4.

[0053] Meanwhile, the exhaust port formed in the above-described exhaust valve (200) and performing the function of exhaling the wearer's exhalation may be formed in multiple numbers. As an example, the exhaust port may include a first exhaust port (211) formed in the lower housing (210) constituting the above-described exhaust valve (200) and a second exhaust port (231) formed in the upper housing (230).

[0054] First, to continue the description of the lower housing (210), the above-described lower housing (210) is formed at a location corresponding to one of the locations of the wearer's mouth and nose among the areas of the above-described mask body (100), and a first exhaust port (211) penetrating the mask body (100) may be formed in one area of ​​the lower portion.

[0055] Accordingly, as illustrated in FIG. 5, it can be understood that a hole (130) having a size corresponding to the first exhaust port formed in the lower housing described above is formed in the mask body (100) described above, but is formed at a position corresponding to the position of the first exhaust port of the exhaust valve formed on the outer surface of the mask body.

[0056] Meanwhile, the first exhaust port (211) described above is preferably formed close to the position of the wearer's mouth in order to effectively discharge the wearer's exhalation, and specifically, as shown in FIG. 4, it is preferably formed in a circle with a preset size (e.g., a diameter of 1.5 to 2.5 cm) in one area of ​​the lower portion of the lower housing (210), and most preferably, it is preferably formed in a circle with a diameter of 2 cm.

[0057] Meanwhile, in FIG. 4, a first exhaust port (211) having a circular shape is illustrated as an embodiment of the present invention, but the first exhaust port (211) described above may be modified and changed to be implemented in various polygonal shapes, including a square or pentagon, in addition to a circular shape, and the present invention is not limited thereto.

[0058] Meanwhile, a fixed part (214) may be formed at the upper end of the first exhaust port (211) formed in the lower housing (210).

[0059] The above-described fixing member (214) is formed to protrude in one area of ​​the lower housing (210) in order to fix the valve (220) to be described later, and is formed at the upper end of the above-described first exhaust port (211), but a plurality of such fixing members may be formed within the range of the diameter of the first exhaust port (211).

[0060] Accordingly, it can be understood that one area of ​​the valve (220) is fixed to the lower housing (210) by being joined to the above-described fixed portion (214).

[0061] Meanwhile, referring to FIG. 4, the above-described valve (220) is formed to be larger than the above-described first exhaust port (211), and a hole (221) is formed in an area of ​​the upper portion, and the hole (221) of the valve (220) is inserted and fixed into a fixed portion (214) protruding in an area of ​​the above-described lower housing (210) to block the first exhaust port (211), but it can be understood that an area excluding the fixed area can move according to the wearer's breathing, thereby controlling the opening and closing of the first exhaust port (211).

[0062] In addition, the above-described valve (220) can function to completely block the first exhaust port (211) by being formed to be larger than the size of the first exhaust port (211), and it can be understood that a hole (221) corresponding to the cross-sectional shape and number of the fixing portion (214) is formed so that insertion and fixation to the above-described fixing portion (214) are possible.

[0063] At this time, the valve (220) described above can be configured so that when exhalation occurs from the wearer's mouth and nose, a freely movable portion of the valve (220) is separated from the first exhaust port (211) based on a fixed area thereof, thereby allowing exhalation to be discharged through the first exhaust port (211), and when inhalation occurs from the wearer's mouth and nose, the valve (220) can block the first exhaust port (211) to prevent intake of external air.

[0064] Additionally, it can be understood that the exhaled air discharged through the first exhaust port (211) is discharged to the outside through the second exhaust port (231) formed in the upper housing (230) to be described later.

[0065] In other words, since exhalation is air that is exhaled from the wearer and moves to the outside, and inhalation is a process in which the wearer inhales outside air, when the valve (220) opens through the wearer's exhalation, the wearer's exhalation is discharged through the first exhaust port (211), and when the valve (220) blocks the first exhaust port (211) through the wearer's inhalation, external smoke and harmful substances can be prevented from being inhaled through the first exhaust port (211).

[0066] Additionally, it is preferable to understand that the wearer's exhaled breath discharged through the first exhaust port (211) described above is discharged to the outside through the second exhaust port (231) formed in the upper housing (230).

[0067] Meanwhile, as illustrated in FIG. 4, a cross-shaped support member (2111) may be formed inside the first exhaust port (211) described above. At this time, it can be understood that the support member (2111) described above performs a function of preventing the valve (220) described above from being drawn into the inside of the mask body according to the wearer's breathing.

[0068] At this time, the shape of the support (2111) can be modified and changed in any form as long as it does not interfere with the function of the first exhaust port (211) that discharges exhaled breath from the wearer to the outside, and the present invention is not limited thereto.

[0069] Meanwhile, after the valve (220) is fixed to the lower housing (210) described above, the upper housing (230) can be combined with the lower housing (210) to form one exhaust valve (200).

[0070] At this time, the upper housing (230) described above is coupled to the lower housing (210), as shown in FIG. 1, and a second exhaust port (231) can be formed in one area on both sides and one area on the lower part so that the wearer's exhalation is discharged to the outside.

[0071] Meanwhile, although not shown in the attached drawing, a valve fixing portion (not shown) is formed protruding from an upper portion of the rear surface of the upper housing described above, so that the valve fixing portion described above presses the upper portion of the valve that is coupled to the lower housing, thereby preventing the valve from being separated from the lower housing.

[0072] At this time, it is preferable to understand that the above-described valve fixing part can be formed in a T shape, and accordingly, the upper part of the valve fixing part vertically fixes the upper part of the valve, and the lower part of the valve fixing part stably fixes the upper part of the valve while contacting an area of ​​the support formed in the first exhaust port.

[0073] Meanwhile, as an embodiment of the present invention, the second exhaust port (231) having a hexagonal shape is limitedly illustrated in the attached drawing, but it may be implemented by modifying and changing it to a polygonal shape including a square, a pentagon, etc., or a circle in addition to a hexagon, and the present invention is not limited thereto.

[0074] Meanwhile, continuing the description of the wet smoke mask of the present invention with reference to FIG. 5, a filter part (300) may be formed on the inside of the mask body (100) described above.

[0075] The above-described filter unit (300) is provided with a plurality of filters (310 to 340), and each of the plurality of filters may be formed with an exhaust valve hole (311, 321, 331, 341) that communicates with the above-described exhaust valve.

[0076] In addition, the filter unit (300) described above may include a plurality of filters (310 to 340) composed of a polyethylene film, polyester compressed cotton, MB filter, and carbon fiber activated carbon nonwoven fabric.

[0077] That is, the above-described filter unit (300) can be understood to include a first filter (310) composed of a polyethylene film, a second filter (320) composed of a polyester compressed cotton, a third filter (330) composed of an MB filter, and a fourth filter (340) including a carbon fiber activated carbon nonwoven fabric.

[0078] Meanwhile, the polyethylene film used in the first filter (310) described above is light, flexible, and has excellent waterproof properties, and thus can be understood to function as a kind of waterproof film that prevents the reaction liquid that may seep out from the oxygen generating unit described later, located next to the mask body (100) described above, from being transferred to the mask body.

[0079] In addition, the polyester compressed cotton used in the second filter (320) described above is processed into a compressed form of polyester with excellent flexibility and durability, and is easy to process into a required shape and size, does not absorb water well, is light and soft, and is suitable for use in a mask, and can filter out fine particles and dust, so it has the effect of protecting the respiratory organs of a wearer wearing the wet smoke mask of the present invention.

[0080] Meanwhile, the MB filter (meltblown filter) used in the third filter (330) described above is a non-woven filter made by a manufacturing method of melting a thermoplastic polymer such as polypropylene (PP) and extruding and spinning it through a nozzle, and is a key raw material used as the internal filter of medical and health masks distributed on the market, including KF masks. The method of spraying the melted polypropylene raw material in the form of threads through a nozzle with fine holes is called meltblown, and the thermoplastic polymer sprayed in this way in the form of threads is cooled in the air to form a fiber shape, and during this process, the fibers are randomly combined to form a non-woven fabric, so that the fibers are entangled in a spider web-like structure, making it difficult for fine dust or foreign substances to pass through, and it has the effect of high fine dust capture efficiency, excellent durability, being lightweight, flexible, and having excellent waterproof properties.

[0081] Furthermore, the MB filter described above is made up of microfibers, each measuring 10㎛ or less, intertwined to form a spiderweb-like structure. This creates a structure where the fibers are randomly entangled and stacked, making it difficult for fine foreign matter to pass through. If electrostatic charges are applied through a post-processing process, the filter can be transformed into an electrostatic filter capable of capturing ultrafine dust.

[0082] Meanwhile, the carbon fiber activated carbon nonwoven fabric used in the fourth filter (340) described above is a filter material made by combining carbon fiber and activated carbon, and can effectively remove and filter various chemical and physical substances by using activated carbon with a high surface area and carbon fiber with excellent strength and durability together.

[0083] Activated carbon is generally made from raw materials such as chemically treated coal, wood, and coconut shells, and can be used to adsorb and remove specific substances. The fine particles of activated carbon contained in carbon fiber activated carbon nonwoven fabric can remove harmful gases generated when a fire breaks out, and have the effect of eliminating unpleasant odors.

[0084] Meanwhile, it can be understood that the exhaust valve holes (311, 321, 331, 341) formed in each of the plurality of filters (310 to 340) constituting the filter unit (300) described above are formed in the same position as the through hole (130) formed in the mask body (100) described above, and it is preferable to understand that the wearer's exhaled breath moves to the first exhaust port of the exhaust valve formed on the outside of the mask body (100) through the exhaust valve holes (311, 321, 331, 341) and the through hole (130) and is discharged to the outside through the second exhaust port of the exhaust valve.

[0085] Accordingly, it is preferable that the hole (130) formed in the mask body (100) and the exhaust valve hole (311, 321, 331, 341) formed in the filter part (300) be formed to have the same size, and it is preferable to understand that both the hole (130) and the exhaust valve hole (311, 321, 331, 341) perform the function of exhausting the exhaled breath of the wearer wearing the mask body (100) to the outside through the exhaust valve formed on the outer surface of the mask body (100).

[0086] Meanwhile, as another embodiment of the present invention, although not shown in the attached drawings, a porous filter may be installed in the exhaust valve hole described above.

[0087] The porous filter described above blocks smoke and harmful substances from entering from the outside by covering the exhaust valve hole formed in a perforated shape to communicate with the exhaust valve, and at the same time, due to its porous nature, allows the movement of gas to be smoothly performed, so that the wearer's exhaled breath can be discharged to the outside through the holes formed in the mask body and the first exhaust port and the second exhaust port of the exhaust valve described above.

[0088] Meanwhile, as illustrated in FIG. 5, an oxygen generating unit (400) may be positioned on the outer surface of the filter unit (300) described above.

[0089] That is, it is preferable to understand that the above-described oxygen generating unit (400) is installed on the outer surface of the fourth filter (340) composed of carbon fiber activated carbon nonwoven fabric among the multiple filters of the above-described filter unit (300).

[0090] Meanwhile, referring to FIGS. 5 to 7, the oxygen generating unit (400) described above is installed on the outer surface of the filter unit (300) positioned adjacent to the wearer's face and supplies oxygen generated as the mask body (100) unfolds to the wearer, and may include a Tyvek filter (410), a reaction solution supply unit (420), and an oxygen generating member (430).

[0091] At this time, it can be understood that the oxygen generating unit (400) described above is formed in a form folded in half with respect to the central axis so that it unfolds together with the mask body (100) formed in a form folded in half.

[0092] Meanwhile, the Tyvek filter (410) of the oxygen generating unit (400) described above can be understood as forming the shape of the exterior of the oxygen generating unit (400), and is preferably formed in a size corresponding to the size of the filter unit (300) described above.

[0093] At this time, Tyvek, which constitutes the above-described Tyvek filter (410), is a synthetic material made of high-density polyethylene fibers, and since it is combined without a binder, fine holes are formed, allowing the movement of gases such as water vapor, but providing excellent breathability that does not allow water or other liquids to pass through, and has a continuous structure of long fibers that provides its own microbial barrier function, and is effective in blocking hazardous substances such as asbestos, mold, fiberglass, and lead, and has strong durability and high resilience.

[0094] Accordingly, the above-described Tyvek filter (410) can be understood to be capable of blocking moisture generated in the process of generating oxygen by receiving the reaction liquid and the oxygen generating compound contained in the porous fibers (422) included in the Tyvek filter (410) and the oxygen generating member (430) so as to prevent moisture from escaping to the outside of the Tyvek filter, and to allow only the oxygen generated from the oxygen generating member (430) to be discharged to the outside. Accordingly, by accommodating the reaction liquid and moisture in the Tyvek filter (410), the area between the wet smoke mask of the present invention and the wearer's face can be created as a comfortable, non-humid environment, thereby exerting an effect of helping the wearer breathe smoothly.

[0095] Meanwhile, a reaction solution supply unit (420) and an oxygen generating member (430) may be located inside the above-described Tyvek filter (410).

[0096] First, the reaction solution supply unit (420) may be located within a Tyvek filter (410) and may be composed of a vinyl pack (421) containing the reaction solution and porous fibers (422) wrapping the vinyl pack (421).

[0097] At this time, the reaction solution described above is supplied to the oxygen generating member of the oxygen generating unit to perform the function of generating oxygen, and it can be understood that distilled water (H20) is used. In addition to distilled water, it is also possible to use purified water such as purified water, and the present invention is not limited thereto.

[0098] Meanwhile, the above-described vinyl pack (421) has a reaction solution receiving space (4211) formed in one area where a reaction solution is received, and a horizontal cut groove (4212) formed in one area of ​​the side of the reaction solution receiving space (4211), and one end of the vinyl pack (421) where the above-described reaction solution receiving space (4211) is located is fixed to the rear of the porous fiber (422), and one area of ​​the upper and lower portions of the other end of the vinyl pack (421) where the above-described cut groove (4212) is formed is fixed to one end of the vinyl pack (421), and an area of ​​the upper and lower portions of the other end of the vinyl pack (421) that is not fixed to one end of the vinyl pack (421) can be fixed to the rear of the porous fiber (422).

[0099] At this time, the above-described cutting groove (4212) is formed horizontally in the middle of the left or right region based on the central axis of the above-described vinyl pack (421), but it is preferable that one region of the cutting groove (4212) be formed so as to overlap with the reaction liquid receiving space (4211).

[0100] Meanwhile, the porous fiber (422) described above can perform a function of carrying the discharged reaction liquid and transferring the reaction liquid to an oxygen generating member (430) located in one area of ​​the porous fiber (422) when the cut groove (4212) formed in the vinyl pack (421) described above is cut and the reaction liquid contained in the reaction liquid containing space (4211) of the vinyl pack (421) is discharged.

[0101] In addition, it can be understood that the porous fiber (422) described above carries the reaction liquid discharged from the vinyl pack (421) described above, thereby enabling the reaction liquid to be supplied to the oxygen generating member (430) for a longer period of time compared to a case that does not include the porous fiber (422), thereby performing the function of increasing the oxygen generating efficiency of the oxygen generating member (430).

[0102] At this time, it is preferable to use a fiber with excellent hygroscopicity so that the porous fiber (422) described above can hold distilled water, which is a reaction liquid. For example, it is possible to use cotton fiber, hemp fiber, rayon fiber, modal fiber, tencel fiber, hanji fiber, etc., and the present invention is not limited thereto.

[0103] Therefore, it is preferable to understand that the above-described oxygen generating unit (400) is formed by positioning a reaction solution supply unit (420) including porous fibers (422) and a vinyl pack (421) and an oxygen generating member (430) within a Tyvek filter (410) made of Tyvek material.

[0104] Meanwhile, below, as an embodiment of the present invention, the oxygen generating unit (400) described above will be examined in more detail with reference to FIG. 6, which shows an example of the schematic shape of the reaction liquid supply unit and the oxygen generating member located inside the oxygen generating unit in an unfolded form before the oxygen generating unit (400) described above is folded in half.

[0105] At this time, the oxygen generating unit (400) illustrated in FIG. 6 can be understood as schematically illustrating the rear surface of the Tyvek filter (410), the rear surface of the porous fiber (422), the reaction solution supply unit (421), and the oxygen generating member (430) that constitute the exterior of the oxygen generating unit (400), and it is preferable to understand that in FIG. 6, the front surface of the Tyvek filter (410) and the front surface of the porous fiber (422) are illustrated in a form in which they are omitted.

[0106] Continuing the explanation with reference to FIG. 6 as described above, the oxygen generating unit (400) described above can be understood as having a reaction solution supply unit (420) positioned within a Tyvek film (410) formed of a Tyvek material, a vinyl pack (421) of the reaction solution supply unit (420) positioned in an area of ​​a porous fiber (422) such that the vinyl pack (421) is formed in a form in which the porous fiber (422) surrounds the vinyl pack (421), but the vinyl pack (421) containing the reaction solution is positioned in an area of ​​the upper portion of the porous fiber (422) formed to be smaller than the size of the Tyvek filter (410), and an oxygen generating member (430) composed of an oxygen generating compound is positioned at the bottom of the vinyl pack (421).

[0107] At this time, a reaction solution receiving space (4211) for receiving the reaction solution is formed in the above-described vinyl pack (421), and a cutting groove (4212) may be formed in a horizontal direction from the central axis in one area of ​​the side of the reaction solution receiving space (4211). As illustrated in FIG. 6, a cutting groove (4212) may be formed in a horizontal direction in the middle part of the right area of ​​the above-described vinyl pack (421).

[0108] In addition, in the vinyl pack (421) described above, the B' region of one end of the vinyl pack (421) where the reaction solution receiving space (4211) is located, and the lower region of the other end of the vinyl pack (421) where the cut groove (4212) is formed, that is, the B region which is located at the bottom based on the cut groove (4212) formed in the right region of the vinyl pack (421), are fixed to the back of the porous fiber (422), and when the oxygen generating unit (400) described above is folded in half, the Tyvek film (410) and the reaction solution supply unit (420) are also folded in half, so it can be understood that the A region located at the top based on the cut groove (4212) formed in the vinyl pack (421) is fixed to the A' region of one end of the vinyl pack (421).

[0109] In other words, the oxygen generating unit (400) formed in a form folded in half has one end and the other end of the vinyl pack (421) adjacent to each other, and at this time, the upper end (A) of the other end of the vinyl pack (421) is fixed to one area (A') of one end of the vinyl pack (421), and one area (B, B') of the back of the vinyl pack (421) is fixed to the porous fiber (422).

[0110] Accordingly, it can be understood that as soon as the above-described mask body (100) is unfolded, one area of ​​the vinyl pack (421) of the above-described reaction liquid supply unit (420) is torn, and the reaction liquid is supplied to the oxygen generating member (430) to generate oxygen.

[0111] Meanwhile, the oxygen generating unit (400) folded in half and the reaction solution supply unit (420) included in the oxygen generating unit (400) are formed so that when the mask body is unfolded, the vinyl pack (421) of the reaction solution supply unit (420) is unfolded, and the cut groove (4212) formed in the vinyl pack (421) is torn, and the reaction solution contained in the reaction solution containing space (4211) is discharged, and the porous fiber (422) surrounding the vinyl pack (421) holds the reaction solution, thereby enabling the reaction solution to be continuously supplied to the oxygen generating member (430).

[0112] To explain more specifically with reference to FIG. 7, when the folded oxygen generating unit (400) unfolds, one end of the vinyl pack (421) fixed to the porous fiber (422) in the oxygen generating unit (400) and the lower end of the other end of the vinyl pack (421) unfold along the porous fiber (422), and when the oxygen generating unit (400) is folded in half, the upper end of the other end of the vinyl pack (421) fixed to one end of the vinyl pack (421) remains fixed to the one end of the vinyl pack (421), so that it can be understood that one area of ​​the vinyl pack (421) is torn along the cutting groove (4212) formed in the vinyl pack (421).

[0113] Accordingly, as described above, it is preferable to understand that the reaction liquid is discharged from the torn area of ​​the vinyl pack (421) and carried on the porous fiber (422), and the reaction liquid carried on the porous fiber (422) is transferred to the oxygen generating member (430) located in one area of ​​the porous fiber (422), and oxygen is generated through a chemical reaction between the reaction liquid and the oxygen generating compound constituting the oxygen generating member (430), and the generated oxygen is transferred to the wearer through the Tyvek filter (410) in which fine holes are formed to allow gas movement.

[0114] Meanwhile, as another embodiment of the present invention, when the oxygen generating unit (400) described above is formed in a form folded in half, it is possible for the upper end of the other end of the vinyl pack located at the upper end based on the cut groove (4212) formed in the vinyl pack (421) described above to be fixed to the porous fiber (422), and for the lower end of the other end of the vinyl pack to be fixed to one area of ​​one end of the vinyl pack, and the present invention is not limited thereto.

[0115] Meanwhile, the oxygen generating member (430) described above may be composed of an oxygen generating compound that receives the reaction liquid supplied from the reaction liquid supply unit (420) described above and causes a chemical reaction to generate oxygen.

[0116] Specifically, it is preferable to understand that the above-described oxygen generating member (430) is inserted into the above-described oxygen generating unit (400) in the form of an oxygen patch made of an oxygen generating compound, and is positioned in one area of ​​the porous fiber (422) of the above-described reaction liquid supply unit (420).

[0117] Meanwhile, the above-described oxygen-generating compound is a compound that generates oxygen by reacting with a reaction solution, and can be formed by mixing an oxidizing agent including at least one of potassium superoxide (KO2) and sodium peroxide (Na2O2), a stabilizer including at least one or two or more of calcium hydroxide (Ca(OH)2), aluminum hydroxide (Al(OH)3), and magnesium hydroxide (Mg(OH)2), and silica gel and carrageenan in a preset ratio.

[0118] At this time, it is preferable to use distilled water as the reaction solution described above, but it is also possible to use purified water in addition to distilled water, and the present invention is not limited thereto.

[0119] Meanwhile, the aforementioned potassium superoxide exists as a yellow solid and is produced when potassium is heated in a glass tube over a long period of time while passing through dry air. It reacts with water to release oxygen and produce potassium hydroxide (KOH) (see Reaction Scheme 1), and is known as a powerful oxidizing agent.

[0120]

[0121] The sodium peroxide described above exists in the form of yellowish-white granules or powder and is called sodium peroxide or sodium dioxide. It functions as an oxidizing agent by reacting with water to produce sodium hydroxide (NaOH) and oxygen (see Reaction Scheme 2).

[0122]

[0123] Therefore, in the present invention, it is preferable to understand that the above-described oxygen generating compound and the distilled water (H2O), which is the reaction liquid contained in the vinyl pack of the above-described reaction liquid supply unit, can react to generate oxygen.

[0124] Meanwhile, the oxygen generating compound of the present invention includes a stabilizer composed of a hydroxide of an alkaline earth metal to stabilize the reactivity when the oxidizing agents, potassium superoxide and sodium peroxide, react with the reactant, and includes at least one selected from calcium hydroxide (Ca(OH)2), aluminum hydroxide (Al(OH)3), and magnesium hydroxide (Mg(OH)2).

[0125] At this time, calcium hydroxide is a basic compound in the form of a white powder. It does not dissolve well in water, with only about 0.82 g dissolving in 1 L of water. However, it has the characteristic of high ionization (dissociation). For this reason, calcium hydroxide dissolved in water exhibits strong alkalinity, with a pH of about 12.5.

[0126] Meanwhile, aluminum hydroxide, an amphoteric hydroxide of aluminum, reacts with acids to form aluminum salts and with alkalis to form aluminates. In particular, prolonged contact with water causes it to gel, and the gel-like aluminum hydroxide exhibits strong adsorptive properties.

[0127] Magnesium hydroxide also exists naturally as hydrochloric acid. When magnesium salts are treated with alkaline hydroxide, they form a colorless colloidal precipitate. Furthermore, when exposed to air, the solid absorbs carbon dioxide and releases it as magnesium carbonate, making it a useful tool for carbon dioxide treatment.

[0128] Meanwhile, the oxygen generating compound of the present invention may include silica gel and carrageenan, which have properties of absorbing moisture, to absorb moisture generated together with oxygen generated through a chemical reaction between the oxidizing agent and stabilizer constituting the oxygen generating compound as described above and distilled water (H2O), which is a reaction solution.

[0129] The silica gel described above is a glossy granular porous material whose main component is silicon dioxide (SiO2). Due to its porous structure, it has a very large surface area of ​​approximately 800 m2 / g, and has an excellent moisture absorption effect. The microscopic pores on the surface of the silica gel can provide a space for moisture absorption, and thus can perform the function of adsorbing moisture in the air.

[0130] In addition, the carrageenan mentioned above is a polysaccharide extracted from red algae (seaweed that lives in coastal waters and has a red or purple color), and is widely used as a thickener, stabilizer, and gelling agent. It has the property of turning into a gel when it absorbs moisture, so it can perform the function of retaining moisture and not releasing it.

[0131] Therefore, the oxygen-generating compound of the present invention can remove moisture generated through a chemical reaction between the oxygen-generating compound and the reaction solution by including silica gel and carrageenan that absorb moisture, thereby preventing the inside of the oxygen-generating unit from becoming hot due to moisture generated through the chemical reaction, thereby preventing low-temperature burns. In addition, by preventing excessive moisture from being generated inside the Tyvek filter of the oxygen-generating unit described above, it is possible to prevent moisture from being discharged to the outside of the oxygen-generating unit, thereby preventing the wearer of the wet-type smoke mask of the present invention from being exposed to moisture that may interfere with breathing in addition to oxygen generated from the oxygen-generating unit.

[0132] Meanwhile, the oxygen generating member (430) of the present invention was tested by applying the EPA 9045D, EPA 6010B, EPA 7471A, and EPA 8260B test methods among the test methods for analyzing environmental pollutants established by the U.S. Environmental Protection Agency (EPA), and as a result, the chemical stability was confirmed as the pH was higher than 12 and no components such as volatile organic compounds were detected, and it was confirmed to be helpful for sterilization, antibacterial, deodorization, fragrance provision, oxygen supply, moisture removal, and carbon dioxide reduction.

[0133] Therefore, the oxygen generating member (430) of the present invention can exert effects that help in sterilization, antibacterial, deodorization, fragrance and oxygen supply, moisture removal, carbon dioxide reduction, etc., and by applying the oxygen generating member (430) to the wet smoke mask of the present invention, it can be understood that it can provide effects such as sterilization, antibacterial, and deodorization while blocking smoke and harmful substances generated in the event of a fire, and can supply fragrance and oxygen to a wearer wearing the wet smoke mask of the present invention, and can exert effects that can reduce unnecessary moisture and carbon dioxide inside the mask.

[0134] Meanwhile, as another embodiment of the present invention, in the case where the cut line (4212) of the vinyl pack (421) of the reaction solution supply unit (420) described above is not properly cut, and thus the reaction solution is not delivered to the oxygen generating member (430) of the oxygen generating unit (400), it is also possible for water vapor (H2O) and carbon dioxide (CO2) contained in the wearer's exhaled breath to be delivered to the oxygen generating member (430) in the oxygen generating unit (400) through the Tyvek filter (410) of the oxygen generating unit (400) to generate oxygen, and the present invention is not limited thereto.

[0135] At this time, when the oxygen generating compound of the oxygen generating member (430) reacts with water vapor contained in the wearer's exhaled breath, it can be understood that oxygen is generated through the same process as the process in which the reaction liquid and the oxygen generating compound react as described above.

[0136] In addition, it can be understood that when the oxygen generating compound of the oxygen generating member (430) reacts with carbon dioxide contained in the wearer's exhaled breath, oxygen can be generated through the following process.

[0137] For example, potassium superoxide, an oxygen-generating compound constituting the oxygen-generating member (430), can react with carbon dioxide contained in the wearer's exhaled breath to release oxygen and generate potassium carbonate (see Reaction Formula 3), and the above-described sodium peroxide can react with carbon dioxide to release oxygen and generate sodium carbonate (see Reaction Formula 4).

[0138]

[0139]

[0140] According to one embodiment of the present invention described above, the wet smoke mask capable of generating oxygen according to the present invention is provided in a folded state, and when the smoke mask is unfolded, a region of the reaction liquid supply portion of the oxygen generating unit provided inside the smoke mask is torn, causing the reaction liquid to be discharged and transferred to the oxygen generating member, and the transferred reaction liquid reacts with the oxygen generating member to generate oxygen, thereby safely protecting the respiratory organ of the wearer from smoke generated in the event of a fire and supplying oxygen, thereby having the effect of helping the wearer breathe smoothly.

[0141] In addition, according to one embodiment of the present invention, oxygen can be generated from an oxygen generating unit provided inside the smoke mask simply by unfolding the smoke mask provided in a folded state, thereby enabling rapid use in an emergency situation.

[0142] In addition, according to one embodiment of the present invention, the oxygen generating unit is formed of a Tyvek filter made of Tyvek material, thereby preventing leakage of the reaction liquid from the reaction liquid supply unit introduced into the Tyvek filter, thereby allowing the wearer to receive only the oxygen generated from the oxygen generating unit, thereby creating a comfortable breathing environment.

[0143] In addition, according to one embodiment of the present invention, by including silica gel and carrageenan, which have excellent moisture absorption properties, in addition to an oxidizing agent and a stabilizer, in the oxygen generating compound constituting the oxygen generating member, moisture generated during the oxygen generating process of the oxygen generating compound is absorbed, thereby preventing low-temperature burns caused by moisture generated during the oxygen generating process of the oxygen generating compound.

[0144] Although the wet smoke mask capable of generating oxygen proposed in the present invention has been described above, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention will be able to easily propose other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit scope of the present invention.

[0145] In addition, terms such as "include," "comprise," or "have" described above, unless specifically stated otherwise, mean that the corresponding component may be included, and therefore should be interpreted to include other components rather than excluding other components. All terms, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which the present invention pertains, unless otherwise defined. Commonly used terms, such as terms defined in a dictionary, should be interpreted to be consistent with the meaning in the context of the relevant technology, and shall not be interpreted in an ideal or overly formal sense, unless explicitly defined in the present invention.

[0146] The above description is merely an illustrative description of the technical idea of ​​the present invention, and those skilled in the art will appreciate that various modifications and variations may be made without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the technical idea of ​​the present invention, and the scope of the technical idea of ​​the present invention is not limited by these embodiments.
