Description

Industrial dust mask containing oxygen generating element

[0001] The present invention relates to a dust mask capable of blocking harmful substances generated in industrial sites, and more particularly, to an industrial dust mask including an oxygen generating member that can help the wearer breathe smoothly by supplying oxygen while safely protecting the respiratory organs of the wearer from harmful substances generated in industrial sites by inserting an oxygen generating member into an exhaust section of the dust mask, thereby discharging the wearer's exhaled breath to the outside through the exhaust section and simultaneously transferring some of the exhaled breath to the oxygen generating member to generate oxygen, and receiving the oxygen generated from the oxygen generating member again while the wearer inhales.

[0002] In general, dust masks are protective equipment worn by workers working in industrial sites where dust is generated, to protect the health of workers by blocking dust generated during work from entering the body through the mouth and nose.

[0003] These conventional dust masks are composed of a mask body that covers the mouth and nose, an intake port installed on both sides of the mask body and having a built-in filter, an exhaust port installed on the lower middle side of the mask body, and a fixing member that is connected to the mask body with a band and fixes the mask body to the head so that it is attached to the face.

[0004] Wearing a dust mask as described above while performing work will cover your mouth and nose while allowing you to breathe through the intake and exhaust ports, thereby preventing harmful substances generated during work from entering your body through your mouth and nose.

[0005] However, when the wearer of a conventional dust mask exhales, the pressure in the space between the mask body and the wearer's face rapidly increases, causing the mask body to rise from the face and exhale. At this time, the breath exhaled through the space in the upper part of the mask body, that is, the nose area, causes the wearer's glasses to fog up, which increases the risk of safety accidents by obstructing vision and creating dangerous situations.

[0006] In an effort to solve the above problem, Korean Patent No. 10-1692949 discloses a technology for a dust mask that prevents fogging on glasses by guiding the breath exhausted from the upper part of the mask body to the lower part of the mask through a separate space inside the mask and quickly exhausting the breath.

[0007] However, in the case of the above-described prior art, the wearer's exhalation is guided to the lower part of the mask and discharged, so that the exhalation is not discharged to the upper part of the mask, which has the advantage of preventing fogging. However, since the mask is tightly attached to the wearer's face, the supply of oxygen is not smooth, which may cause problems in breathing while wearing the mask for a long time.

[0008] The present invention was created to solve the above problems, and the purpose of the present invention is to provide an industrial dust mask that can safely protect the respiratory organs of the wearer from harmful substances generated in industrial sites while supplying oxygen by inserting an oxygen generating member into the exhaust section of the dust mask, thereby exhausting the wearer's exhaled breath to the outside through the exhaust section and simultaneously transferring some of the exhaled breath to the oxygen generating member to generate oxygen, and receiving the oxygen generated from the oxygen generating member again while the wearer inhales, thereby helping the wearer breathe smoothly.

[0009] In order to achieve the above object, an industrial dust mask including an oxygen generating member according to an embodiment of the present invention comprises: a mask body; a fixing band that enables the mask body to be fixed to the face of a wearer; an exhaust part formed in one area of ​​an outer surface of the mask body and having an exhaust port formed therein so that the wearer's exhaled breath can be discharged to the outside; and an oxygen generating member inserted into one area within the exhaust part to receive water vapor and carbon dioxide generated from the wearer's breath and cause a chemical reaction to generate oxygen; wherein a through hole is formed penetrating one area of ​​the mask body and the exhaust part, so that a portion of the wearer's exhaled breath discharged to the outside through the exhaust port of the exhaust part is transferred to the oxygen generating member inserted within the exhaust part through the through hole to generate oxygen, and oxygen generated from the oxygen generating member is supplied to the wearer through the through hole when inhalation occurs from the wearer's mouth and nose.

[0010] The exhaust part is 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 a lower housing having a first exhaust port penetrating the mask body formed in a region of the lower portion and a first through hole penetrating the mask body formed in a region of the upper portion; a lower housing having a larger size than the first exhaust port and a hole formed in a region of the upper portion, the hole being inserted and fixed into a fixing portion protruding in a region of the lower housing to block the first exhaust port, and a valve having an area excluding the fixed area that is movable according to the wearer's breathing; an upper housing coupled to the lower housing, and having a second exhaust port formed in a region of one of both sides and one of the lower portion so that the wearer's exhaled breath is discharged to the outside; And an intermediate housing in which the oxygen generating member is inserted into the upper housing, and then inserted into the inside of the upper housing to fix the oxygen generating member, a second aperture is formed at a position corresponding to the first aperture, a third exhaust port having a shape corresponding to the second exhaust port is formed in one area of ​​both sides and one area of ​​the lower portion, and a valve fixing portion is protruded from one area of ​​the lower portion to fix the upper portion of the valve; wherein, when the intermediate housing is coupled to the upper housing, the second exhaust port and the third exhaust port are preferably arranged on the same line.

[0011] The lower housing includes a partition separator formed by protruding from an area of ​​the upper surface of the lower housing and formed in an area between the first hole and the fixing portion; and when the upper housing having the intermediate housing inserted therein is coupled to the lower housing, it is preferable that the partition separator protrude and come into close contact with the lower end of the second hole formed in the intermediate housing to vertically partition the area between the lower housing and the intermediate housing.

[0012] It is preferable that the first and second openings are aligned in a straight line so that when exhalation is generated from the wearer's mouth and nose, some of the exhalation is transmitted to the oxygen generating member through the first and second openings inside the mask body, and when inhalation is generated from the wearer's mouth and nose, oxygen generated from the oxygen generating member is supplied to the wearer inside the mask body through the second and first openings.

[0013] The lower housing is preferably formed with a protrusion and a joining groove along the outer circumference 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, such that the joining protrusion of the upper housing is inserted into the joining groove of the lower housing, and at the same time, the lower end of the intermediate housing inserted into the upper housing is in close contact with the upper surface of the joining protrusion, and the lower end of the upper housing is fitted into the joining protrusion, so that the lower housing, the valve, the intermediate housing, the oxygen generating member, and the upper housing are joined in that order, thereby forming the exhaust unit that includes the oxygen generating member therein.

[0014] The valve is configured such that, when exhalation occurs from the wearer's mouth and nose, a freely movable portion of the valve relative to a fixed area thereof is separated from the first exhaust port, thereby allowing the exhalation to be discharged through the first exhaust port, and when inhalation occurs from the wearer's mouth and nose, the first exhaust port is blocked, thereby preventing intake of outside air. However, it is preferable that the exhalation discharged through the first exhaust port is discharged to the outside through the second exhaust port and the third exhaust port.

[0015] It is preferable that the oxygen generating member include an oxygen generating compound that generates oxygen by reacting with a reactant including at least one of water vapor and carbon dioxide; and a pouch formed in a film shape of a preset size and containing the oxygen generating compound therein.

[0016] 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.

[0017] It is preferable that the above pouch is formed of at least one material selected from the group consisting of Tyvek, elastic non-woven fabric, polyamide, and polyethylene terephthalate.

[0018] An industrial dust mask including an oxygen generating member according to the present invention has the effect of allowing the oxygen generating member to be inserted into an exhaust port of the dust mask, thereby discharging the wearer's exhaled breath to the outside through the exhaust port and simultaneously transferring some of the exhaled breath to the oxygen generating member to generate oxygen, and safely protecting the wearer's respiratory organs from harmful substances generated in industrial sites by receiving the oxygen generated from the oxygen generating member again while the wearer inhales, thereby supplying oxygen and helping the wearer breathe smoothly.

[0019] 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.

[0020] In addition, according to one embodiment of the present invention, the oxygen generating member has the effect of helping to remove coronavirus, sterilize, antibacterial, deodorize, provide fragrance, and supply oxygen.

[0021] Accordingly, by applying an oxygen generating member according to an embodiment of the present invention to a dust mask, it is possible to provide effects such as blocking harmful substances generated in industrial sites, removing coronavirus, sterilizing, antibacterial, and deodorizing, and supplying fragrance and oxygen to a wearer wearing the dust mask.

[0022] In addition, according to one embodiment of the present invention, by providing an oxygen generating member in a film form, the size of an exhaust portion into which the oxygen generating member is inserted can be effectively reduced, thereby providing convenience to the wearer in using the dust mask.

[0023] In addition, according to one embodiment of the present invention, by dividing an area within an exhaust section into upper and lower sections through a partition, a portion of the wearer's exhaled breath is transferred to an oxygen generating member through a first hole and a second hole formed in an upper section of the exhaust section, and the remaining exhaled breath is discharged to the outside through the first to third exhaust ports formed in a lower section of the exhaust section, thereby controlling the amount of the wearer's exhaled breath transferred to the oxygen generating member, thereby improving the efficiency of oxygen generation generated from the oxygen generating member, and improving the wearer's breathing environment and preventing air contamination inside the mask body.

[0024] In addition, according to one embodiment of the present invention, by dividing the area within the exhaust section into upper and lower sections, oxygen generated from the oxygen generating member is directly delivered to the wearer through the first and second holes formed in the upper portion of the exhaust section, thereby preventing oxygen from leaking out, thereby effectively supplying oxygen to the wearer.

[0038] The present invention relates to an industrial dust mask including an oxygen generating member, and more specifically, to an industrial dust mask in which an oxygen generating member is inserted into an exhaust portion of the dust mask, thereby discharging the wearer's exhaled breath to the outside through the exhaust portion and simultaneously transferring some of the exhaled breath to the oxygen generating member to generate oxygen, and when the wearer inhales, the oxygen generated from the oxygen generating member is transferred again, thereby safely protecting the wearer's respiratory organs from harmful substances generated in industrial sites and supplying oxygen to help the wearer breathe smoothly.

[0039] 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.

[0040] Looking briefly at the drawings attached as a description of the present invention, FIG. 1 shows an example of a schematic shape of an industrial dust mask including an oxygen generating member according to an embodiment of the present invention, FIG. 2 shows an exploded view of an exhaust part according to an embodiment of the present invention, FIG. 3 shows an example of a schematic shape of a lower housing according to an embodiment of the present invention, FIG. 4 shows an example of a shape in which a valve is coupled to a lower housing according to an embodiment of the present invention, and FIG. 5 shows an example of a schematic shape of an intermediate housing according to an embodiment of the present invention. In addition, FIG. 6 shows an example of a schematic shape of an upper housing according to an embodiment of the present invention, FIGS. 7 and 8 show side cross-sectional views of an industrial dust mask including an oxygen generating member according to an embodiment of the present invention, and FIGS. 9 to 13 show examples of industrial dust masks including oxygen generating members according to other embodiments of the present invention.

[0041] Meanwhile, in the following description, some of the details 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 should be understood that the details depicted do not limit the technical features and scope of rights of the present invention.

[0042] Referring to FIG. 1, which illustrates an example of a schematic shape of an industrial dust mask including an oxygen generating member according to an embodiment of the present invention, and FIG. 2, which illustrates an exploded view of an exhaust section, the industrial dust mask including an oxygen generating member according to the present invention is largely composed of a mask body (100), a fixing band (200), an exhaust section (300), and an oxygen generating member (400).

[0043] First, the mask body (100) described above constitutes the overall exterior of an industrial dust mask (hereinafter referred to as the 'dust mask of the present invention') including the oxygen generating member of the present invention, and can be formed in a form that simultaneously shields the mouth and nose of the wearer.

[0044] At this time, the mask body (100) described above can be configured to have various materials and structures according to the standards of industrial dust masks, which are classified into special, first, and second grades according to capture efficiency, leakage rate, etc. In the following description, the mask body (100) can be configured to basically include the shape and material of all known types of masks, and the present invention is not limited thereto.

[0045] In addition, it is preferable to understand that the present invention forms an exhaust valve type dust mask among the face filtering type and detachable dust masks.

[0046] 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.

[0047] This can be understood as being for bending the above-described nose support (110) to correspond to the shape of the wearer's nose bridge so that the mask body (100) is pressed against the wearer's nose bridge.

[0048] Meanwhile, although not shown in the attached drawing, as another embodiment of the present invention, a silicone portion (not shown) may be formed along the inner edge of the mask body adjacent to the wearer's face.

[0049] At this time, the silicone part described above can function to securely block outside air by closely contacting the wearer's skin when the mask body is worn. In addition, since the silicone part is formed using an elastic silicone material, it can be understood that when the wearer wears the mask body, the silicone part adheres tightly along the curves of the wearer's face without lifting, thereby fundamentally blocking outside air or outside pollutants from flowing in between the mask body and the wearer's face.

[0050] Returning to Fig. 1 and continuing the explanation, a fixing band (200) may be formed on the left and right sides of the above-described mask body (100). The above-described fixing band (200) is a member that enables the above-described mask body to be fixed to the wearer's face, and is preferably formed in a shape that wraps around the wearer's head so that it does not easily detach from the wearer's face.

[0051] At this time, the above-described fixed band (200) can be manufactured using a fiber material of elastic material, so that it can be adjusted elastically according to the wearer's head size and has the effect of providing a soft wearing feeling.

[0052] In addition, the above-described fixed band (200) may be made of an elastic rubber material band, but in addition to the rubber material band, it is also possible to use a material that is elastic and easy to adjust the length, and the present invention is not limited thereto.

[0053] Meanwhile, although not illustrated in the attached drawing, as another embodiment of the present invention, the above-described fixed band (200) may be formed to further include a length adjustment portion (not illustrated) so as to have a structure in which the length of the fixed band is adjusted. In this case, the above-described length adjustment portion performs the function of finely adjusting the length of the fixed band to match the head circumference of the wearer, thereby exerting the effect of more stably fixing the dust mask of the present invention to the wearer's face.

[0054] 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 surrounds the wearer's head, but it is also possible to use a fixed band that is hung on the ear, and the present invention is not limited thereto.

[0055] In another embodiment of the present invention, when the above-described fixed band is used as a fixed band in the form of an ear-hanging type, the function of adjusting the length of the fixed band and improving the wearing comfort can be performed through an additional structure such as a hook. This is done 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 bands formed at both ends of the mask body, thereby improving the wearing comfort, and when the dust 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.

[0056] Meanwhile, an exhaust part (300) may be formed in the above-described mask body (100).

[0057] The exhaust part (300) is formed in one area of ​​the outer surface of the mask body (100) described above, as shown in FIGS. 1 to 6, and an exhaust port may be formed so that the wearer's exhaled breath can be discharged to the outside.

[0058] At this time, the exhaust unit (300) described above may include a lower housing (310), a valve (320), a middle housing (330), and an upper housing (340).

[0059] Meanwhile, a plurality of exhaust ports formed in the exhaust section (300) and performing the function of discharging the wearer's exhalation may be formed. As an example, the exhaust section (300) described above may include a first exhaust section (311) formed in the lower housing (310), a third exhaust section (332) formed in the middle housing (330), and a second exhaust section (341) formed in the upper housing (340).

[0060] First, to continue the explanation of the lower housing (310), the above-described lower housing (310) is formed at a location corresponding to one of the positions of the wearer's mouth and nose among the areas of the mask body (100), and a first exhaust port (311) penetrating the mask body (100) may be formed in one area of ​​the lower portion, and a first through hole (315) penetrating the mask body (100) may be formed in one area of ​​the upper portion.

[0061] At this time, the first exhaust port (311) 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. 3, 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 (310), and most preferably, it is preferably formed in a circle with a diameter of 2 cm.

[0062] Meanwhile, in FIG. 3, a first exhaust port (311) having a circular shape is illustrated as a limited embodiment of the present invention, but the first exhaust port (311) 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.

[0063] Meanwhile, a fixed part (312) may be formed at the upper end of the first exhaust port (311) formed in the lower housing (310).

[0064] The above-described fixing portion (312) is formed to protrude in one area of ​​the lower housing (310) in order to fix the valve to be described later, and as shown in FIG. 3, is formed at the upper end of the above-described first exhaust port (311), but a plurality of such fixing portions may be formed within the range of the diameter of the first exhaust port (311).

[0065] Accordingly, it can be understood that one area of ​​the valve is fixed to the lower housing (310) by being joined to the above-described fixing portion (312).

[0066] Meanwhile, the first opening (315) described above is formed at the upper end of the lower housing (310), as shown in FIGS. 3 and 4, and is formed by penetrating the mask body, so that it can be understood as a passage through which some of the exhaled breath generated from the wearer wearing the mask body moves.

[0067] At this time, the first hole (315) described above is preferably provided in multiple pieces as shown in FIGS. 3 and 4, but may also be formed as one piece, and its shape and size may be changed as needed, and the present invention is not limited thereto.

[0068] Meanwhile, referring to FIG. 4, the above-described valve (320) is formed to be larger than the above-described first exhaust port (311), and a hole (321) is formed in an area of ​​the upper portion, and the hole (321) is inserted and fixed into a fixed portion (312) protruding in an area of ​​the above-described lower housing (310) to block the first exhaust port (311), 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 (311).

[0069] In addition, the above-described valve (320) can function to completely block the first exhaust port (311) by being formed to be larger than the size of the first exhaust port (311), and it can be understood that a hole (321) corresponding to the cross-sectional shape and number of the fixing portion (312) is formed so that insertion and fixation to the above-described fixing portion (312) are possible.

[0070] At this time, the valve (320) described above can be configured so that when exhalation occurs from the wearer's mouth and nose, a freely movable portion of the valve (320) is separated from the first exhaust port (311) based on a fixed area thereof, thereby allowing exhalation to be discharged through the first exhaust port (311), and when inhalation occurs from the wearer's mouth and nose, the valve (320) can block the first exhaust port (311) to prevent intake of external air.

[0071] In addition, it can be understood that the exhaled air discharged through the first exhaust port (311) is discharged to the outside through the second exhaust port formed in the upper housing to be described later and the third exhaust port formed in the middle housing to be described later.

[0072] Specifically, as illustrated in (B) of FIG. 7, it can be understood that when the wearer exhales, the lower part of the valve (320) that is not fixed moves outward from the mask body (100) and the first exhaust port (311) based on the fixed upper part, so that the valve (320) separates from the first exhaust port (311), and the wearer's exhalation is discharged from the inside of the mask body (100) to the first exhaust port (311), and as illustrated in (A) of FIG. 7, when the wearer inhales, the lower part of the valve (320) that is not fixed moves again toward the first exhaust port (311) to block the first exhaust port (311), thereby blocking the intake of outside air.

[0073] 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 (320) opens through the wearer's exhalation, water vapor and carbon dioxide contained in the wearer's exhalation are discharged through the first exhaust port (311), and when the valve (320) blocks the first exhaust port (311) through the wearer's inhalation, harmful substances from the outside can be prevented from being inhaled through the first exhaust port (311).

[0074] In addition, although not shown in FIG. 7, it is preferable to understand that the wearer's exhaled breath discharged through the first exhaust port (311) described above is discharged to the outside through the second exhaust port formed in the middle housing (330) and the third exhaust port formed in the upper housing (340).

[0075] Meanwhile, as illustrated in FIG. 3, a cross-shaped support member (3111) may be formed inside the first exhaust port (311) described above. At this time, it can be understood that the support member (3111) described above performs a function of preventing the valve (320) described above from being drawn into the inside of the mask body according to the wearer's breathing.

[0076] At this time, the shape of the support (3111) may be modified and changed in any form as long as it does not interfere with the function of the first exhaust port (311) formed to enable the movement of exhaled breath from the wearer and oxygen generated from an oxygen generating member to be described later and delivered to the wearer, and the present invention is not limited thereto.

[0077] Returning to FIG. 2 and continuing the explanation, after the valve (320) is fixed to the lower housing described above, the upper housing (330) in which the oxygen generating member (400) and the intermediate housing (330) are inserted can be combined with the lower housing (310) to form one exhaust section (300).

[0078] At this time, the upper housing (340) described above is coupled to the lower housing (310), as shown in FIGS. 1 and 2, and a second exhaust port (341) 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.

[0079] Meanwhile, an oxygen generating member (400) can be inserted into the upper housing (340) described above, and after the oxygen generating member (400) is inserted, an intermediate housing (330) can be inserted to fix the oxygen generating member (400) to the upper housing (340).

[0080] Specifically, the intermediate housing (330) described above is inserted into the upper housing (340) after the oxygen generating member (400) is inserted therein as shown in FIG. 2, and the oxygen generating member (400) is fixed by being inserted into the inside of the upper housing (340). As shown in FIG. 5, a second hole (331) is formed at a position corresponding to the first hole (315) of the lower housing (310) described above, and a third exhaust port (332) having a shape corresponding to the second exhaust port (341) of the upper housing (340) described above is formed in one area of ​​both sides and one area of ​​the lower portion, and a valve fixing portion (333) is formed to protrude from one area of ​​the lower surface to fix the upper portion of the valve (320) described above.

[0081] At this time, when the middle housing (330) is coupled to the upper housing (340), it is preferable that the second exhaust port (341) of the upper housing (340) and the third exhaust port (332) of the middle housing (330) be arranged on the same line.

[0082] Specifically, the third exhaust port (332) of the middle housing (330) is formed in a shape corresponding to the shape of the second exhaust port (341) of the upper housing (340), and is arranged on the same line as the second exhaust port (341) to form a single passage, so that when the wearer's exhaled breath is discharged from the wearer wearing the mask body through the first exhaust port (311) formed by penetrating the mask body and the lower housing (310), it can be understood that the exhaled breath is discharged to the outside through the second exhaust port (341) and the third exhaust port (332).

[0083] Accordingly, it is desirable to understand that the shapes and positions of the second exhaust port (341) and the third exhaust port (332) are formed to correspond to each other in order to facilitate the discharge of the wearer's exhalation.

[0084] Meanwhile, as an embodiment of the present invention, the second exhaust port and the third exhaust port are limitedly illustrated in the attached drawing as having a hexagonal shape, but they may be modified and changed to have 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.

[0085] Meanwhile, the second aperture (331) formed in the above-described intermediate housing (330) is formed in the upper portion of the intermediate housing (330), as illustrated in FIG. 2, and is formed by penetrating the intermediate housing (330), and is formed in a number and shape corresponding to the first aperture (315) of the lower housing (310), so that it can be understood that some of the exhaled breath generated from a wearer wearing the mask body enters the first aperture (315) and is transmitted to the oxygen generating member (400) inserted between the upper housing (340) and the intermediate housing (330) through the second aperture (331).

[0086] At this time, the second hole (331) described above is preferably provided in multiple pieces as shown in FIG. 2, but may also be formed as one piece, and its shape and size may be changed as needed, and the present invention is not limited thereto.

[0087] Returning to FIG. 5 and continuing the explanation, it is preferable to understand that the valve fixing portion (333) formed in the above-described intermediate housing (330) can be formed in a T shape, and accordingly, the upper portion of the valve fixing portion (333) vertically fixes the upper portion of the valve (320), and the lower portion of the valve fixing portion (333) is in contact with an area of ​​the support (3111) formed in the first exhaust port (311), thereby stably fixing the upper portion of the valve (320).

[0088] Meanwhile, the oxygen generating member (400) described above, as shown in FIG. 2, is inserted into an area within the exhaust section and can receive water vapor and carbon dioxide generated from the wearer's breath to cause a chemical reaction and generate oxygen.

[0089] Specifically, a hole is formed that penetrates a region of the mask body (100) and the exhaust section (300), so that a portion of the wearer's exhaled breath discharged to the outside through the exhaust port of the exhaust section (300) is transferred to the oxygen generating member (400) inserted into the exhaust section through the hole to generate oxygen, and it can be understood that the oxygen generated from the oxygen generating member (400) is supplied to the wearer again through the hole when the wearer inhales through the mouth and nose.

[0090] At this time, the above-described aperture may include a first aperture (315) formed in the lower housing (310) and a second aperture (331) formed in the middle housing (330) as described above.

[0091] Meanwhile, as an embodiment of the present invention, the first hole (315) formed in the lower housing (310) and the second hole (331) formed in the middle housing (330) are aligned in a straight line so that when exhalation is generated from the mouth and nose of the wearer, some of the exhalation is transmitted to the oxygen generating member (400) through the first hole (315) and the second hole (331) inside the mask body, and when inhalation is generated from the mouth and nose of the wearer, oxygen generated from the oxygen generating member (400) is supplied to the wearer inside the mask body through the second hole (331) and the first hole (315).

[0092] More specifically, it can be understood that the oxygen generating member (400) is inserted between the upper housing (340) and the middle housing (330) of the exhaust unit, and receives a portion of the exhaled breath generated from the wearer wearing the mask body through the first opening (315) formed in the lower housing (310) of the exhaust unit and the second opening (331) formed in the middle housing (330), thereby generating oxygen by causing a chemical reaction with water vapor and carbon dioxide contained in the exhaled breath, and the generated oxygen is supplied to the wearer again through the second opening (331) and the first opening (315) when the wearer inhales.

[0093] Meanwhile, the oxygen generating member (400) described above is fixed so as not to be detached to the outside by being inserted into the upper housing (340) and the middle housing (330), and is maintained in a sealed state except for the area adjacent to the second hole (331) formed in the middle housing (330), thereby preventing contact with external water vapor and carbon dioxide other than the wearer's exhalation, thereby preventing side effects such as hyperventilation, oxygen poisoning, headache, and dizziness from occurring to the wearer due to the generation of more oxygen than necessary.

[0094] Returning to FIGS. 3 and 4 and continuing the explanation, the lower housing (310) described above may include a partition separator (314) for partitioning the area within the exhaust section into upper and lower sections.

[0095] Specifically, the compartment separation part (314) can be understood as being formed by protruding from an area of ​​the upper surface of the lower housing (310), and formed in an area between the first through hole (315) described above and the fixing part (312) described above.

[0096] Accordingly, as one embodiment of the present invention, when the upper housing (340) having the intermediate housing (330) inserted inside is coupled to the lower housing (310), the above-described partition separator (314) can perform the function of vertically partitioning the area between the lower housing (310) and the intermediate housing (330) by having the protruding end come into close contact with the lower end of the second hole (331) formed in the intermediate housing (330), as shown in FIG. 7.

[0097] At this time, since the area between the lower housing (310) and the middle housing (330) is partitioned vertically through the above-described partition separation section (314), some of the wearer's exhaled breath is transferred to the oxygen generating member (400) through the first hole (315) and the second hole (331) formed in the upper part of the exhaust part, and the remaining exhaled breath is discharged to the outside through the first to third exhaust ports formed in the lower part of the exhaust part, thereby controlling the amount of the wearer's exhaled breath transferred to the oxygen generating member (400) and improving the efficiency of oxygen generation generated in the oxygen generating member (400), and can exhibit the effect of improving the breathing environment of the wearer wearing the dust mask of the present invention and preventing air contamination inside the mask body (100).

[0098] In addition, by dividing the area within the exhaust section into upper and lower sections, oxygen generated from the oxygen generating member (400) is directly delivered to the wearer through the first through hole (315) and the second through hole (331) formed at the upper end of the exhaust section, thereby preventing oxygen from leaking out and effectively supplying oxygen to the wearer.

[0099] Meanwhile, referring to FIGS. 2, 3 and 6 simultaneously, the lower housing (310) described above may have a protrusion (313) and a joining groove (3131) formed along the outer surface of the lower housing (310), and the upper housing (340) described above may have a joining projection (342) formed protrudingly on the lower portion of the upper housing (340) to be inserted into the joining groove (3131) described above.

[0100] Accordingly, it can be understood that the exhaust section is formed by simultaneously inserting the coupling protrusion (342) of the upper housing (340) into the coupling groove (3131) of the lower housing (310), and the lower end of the intermediate housing (330) inserted into the upper housing (340) is in close contact with the upper surface of the protrusion (313), and the lower end of the upper housing (340) is fitted into the protrusion (313).

[0101] At this time, it is preferable to understand that the above-described valve (320) can be positioned between the lower housing (310) and the middle housing (330), the first exhaust part (311) can be positioned on the rear side of the valve (320), and the oxygen generating member (400) can be positioned between the middle housing (330) and the upper housing (340).

[0102] That is, as illustrated in FIG. 2, it can be understood that the above-described lower housing (310), the above-described valve (320), the above-described middle housing (330), the above-described oxygen generating member (400), and the above-described upper housing (340) are sequentially combined to form an exhaust unit (300) that includes the oxygen generating member (400) of the present invention therein.

[0103] Meanwhile, referring to FIGS. 7 and 8 simultaneously, the oxygen generating member (400) described above generates oxygen by receiving water vapor and carbon dioxide contained in the wearer's exhaled breath, and may include an oxygen generating compound (410) and a pouch (420).

[0104] Meanwhile, the above-described oxygen generating compound (410) generates oxygen by reacting with a reactant containing at least one of water vapor and carbon dioxide, and can be formed by mixing an oxidizing agent containing at least one of potassium superoxide (KO2) and sodium peroxide (Na2O2), a stabilizer containing 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.

[0105] 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.

[0106]

[0107] 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).

[0108]

[0109] Meanwhile, the above-described potassium superoxide can react with carbon dioxide to release oxygen and produce potassium carbonate (see Reaction Scheme 3), and the above-described sodium peroxide can react with carbon dioxide to release oxygen and produce sodium carbonate (see Reaction Scheme 4).

[0110]

[0111]

[0112] Therefore, in the present invention, it is preferable to understand that the above-described oxygen generating compound (410) and a reactant including at least one of water vapor (H2O) and carbon dioxide (CO2) generated from the wearer's breath can react to generate oxygen.

[0113] Meanwhile, the oxygen generating compound (410) in the present invention is 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).

[0114] 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.

[0115] Meanwhile, when calcium hydroxide reacts with carbon dioxide (CO2), calcium carbonate (see Reaction Formula 5) is generated through the following reaction formula. The calcium carbonate thus generated can react with carbon dioxide and moisture contained in the air or human exhalation to change into calcium bicarbonate (see Reaction Formula 6), so it can also be usefully used to treat carbon dioxide.

[0116]

[0117]

[0118] 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.

[0119] 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.

[0120] Meanwhile, the oxygen generating compound (410) 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 of a reactant including at least one of water vapor (H2O) and carbon dioxide (CO2) generated from the wearer's breath, and an oxidizing agent and a stabilizer constituting the oxygen generating compound (410) as described above.

[0121] 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.

[0122] 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.

[0123] Therefore, the oxygen generating compound (410) of the present invention can prevent low-temperature burns caused by moisture generated through a chemical reaction between the oxygen generating compound (410) and a reactant including at least one of water vapor (H2O) and carbon dioxide (CO2) by including silica gel and carrageenan that absorb moisture.

[0124] Meanwhile, the above-described pouch (420) is formed in a film shape of a preset size and contains an oxygen generating compound (410) inside, and may be formed of at least one material among Tyvek, elastic non-woven fabric, polyamide, and polyethylene terephthalate.

[0125] At this time, it is preferable that the above-described pouch (420) be formed of a material with excellent porosity so that water vapor and carbon dioxide contained in the wearer's exhaled breath can be transferred to the oxygen generating compound (410) within the pouch (420), and oxygen generated from the oxygen generating compound (410) can be discharged to the outside of the pouch (420).

[0126] Meanwhile, the material forming the above-described pouch (420) is specifically described as follows.

[0127] Tyvek is a synthetic material made from high-density polyethylene fibers. It is bonded without a binder, so it forms microscopic holes, allowing moisture vapor to penetrate the material but not water or other liquids, providing excellent breathability. It has a continuous structure of long fibers that provides its own microbial barrier function, making it effective in blocking hazardous substances such as asbestos, mold, fiberglass, and lead. It also has strong durability and high resilience.

[0128] In addition, the elastic nonwoven fabric is formed by applying an elastic polymer coating agent in a thin film form to a part or the entire surface of an extensible nonwoven fabric to form an elastic nonwoven net on the surface of the nonwoven fabric, and has excellent elasticity and recovery rate.

[0129] In addition, polyamide is a thermosetting or thermoplastic amorphous polymer with excellent mechanical, thermal and chemical resistance, and is used in various fields such as fibers, films and electrical insulators. In particular, when used as fibers, it is durable, chemically stable and elastic, and is mainly used as clothing or industrial materials.

[0130] Polyethylene terephthalate, also known as PET, is a plastic material made by polymerizing ethylene and terephthalic acid. It is evaluated as an environmentally friendly material because it is durable, chemically stable, and recyclable.

[0131] Meanwhile, as an embodiment of the present invention, an oxygen generating member (400) formed by injecting an oxygen generating compound (410) into a film-shaped pouch (420) formed of the material described above may be inserted between the upper housing (340) and the middle housing (330) of the exhaust unit.

[0132] Meanwhile, the oxygen generating member (400) of the present invention was tested by applying EPA 9045D, EPA 6020, EPA 8081A, and EPA 8260B GCMS test methods among the test methods for analyzing environmental pollutants established by the U.S. Environmental Protection Agency (EPA), and as a result, it was confirmed that the chemical stability was confirmed as the pH was greater than 12 and no components such as volatile organic compounds and pesticides were detected. In addition, it was confirmed that it helps in removing coronavirus, sterilizing, antibacterial, deodorizing, imparting fragrance, and supplying oxygen, and thus obtained a certificate as shown in Photo 1 below.

[0136] Hereinafter, with reference to FIGS. 7 and 8, the operation process of the exhaust part according to the transport path of water vapor and carbon dioxide generated through the breathing of a wearer wearing a dust mask of the present invention and the process of oxygen being generated in an oxygen generating member and transferred to the wearer will be described.

[0137] First, as shown in (A) of FIG. 7, the dust mask of the present invention may be formed by sequentially combining a lower housing (310), a valve (320), an intermediate housing (330), and an upper housing (340) on the outer surface of the mask body (100), and an exhaust section in which an oxygen generating member (400) is inserted between the intermediate housing (330) and the upper housing (340).

[0138] When exhalation is generated from a wearer wearing the dust mask of the present invention, as shown in (B) of FIG. 7, the valve (320) blocking the first exhaust port (311) formed by penetrating the mask body (100) and the lower housing (310) moves due to the wearer's exhalation containing water vapor (H2O) and carbon dioxide (CO2), and the first exhaust port (311) is opened, and the exhalation is discharged through the opened first exhaust part (311), and although not shown in FIG. 7, it can be discharged to the outside through a third exhaust port (not shown) formed in the middle housing of the exhaust part and a second exhaust port (not shown) formed in the upper housing.

[0139] Specifically, as illustrated in (B) of FIG. 7, when exhalation is generated from the mouth and nose of a wearer wearing the mask body (100), the lower part that is freely movable based on a fixed area of ​​the valve (320) is separated from the first exhaust port (311) described above, and the first exhaust port (311) is opened, and the exhalation is discharged through the opened first exhaust port (311) and discharged to the outside through the third exhaust port and the second exhaust port of the exhaust part.

[0140] At this time, it can be understood that while the wearer's exhalation is discharged through the first exhaust port (311), some of the exhalation generated from the wearer is transferred to the oxygen generating member (400) inserted between the upper housing (340) and the middle housing (330) of the exhaust unit through the first through-hole (315) formed by penetrating the mask body (100) and the lower housing (310) and the second through-hole (331) formed by penetrating the middle housing (330).

[0141] In addition, it can be understood that when a portion of the wearer's exhaled breath is transferred to the oxygen generating member (400), the water vapor and carbon dioxide contained in the exhaled breath pass through the pouch (420) of the oxygen generating member (400) formed of a porous material and are transferred to the oxygen generating compound (410) within the oxygen generating member (400), and thus the water vapor and carbon dioxide chemically react with the oxygen generating compound (410) to generate oxygen.

[0142] Meanwhile, as illustrated in FIG. 8, when a wearer wearing the mask body (100) breathes, oxygen generated from the oxygen generating member (400) moves into the mask body (100) through the second opening (331) of the middle housing (330) and the first opening (315) formed by penetrating the mask body (100) and the lower housing (310), thereby supplying oxygen to the wearer and allowing the wearer to inhale oxygen into the body.

[0143] On the other hand, the exhaled breath generated from the wearer's breathing contains water vapor and carbon dioxide, and thus has a high density and temperature. Therefore, as illustrated in FIG. 7 (B), when the wearer exhales, the valve (320) moves, the first exhaust port (311) opens, and when the exhaled breath is discharged through the opened first exhaust port (311), the air density inside the mask body (100) decreases, the temperature decreases, and a low pressure may be formed.

[0144] Accordingly, due to the low pressure formed inside the mask body (100), oxygen generated from the oxygen generating member (400) may move into the mask body (100) through the second opening (331) and the first opening (315) and be supplied to the wearer.

[0145] In addition, while oxygen is supplied from the oxygen generating member (400) through the wearer's inhalation or the low pressure formed inside the mask body, the non-fixed lower part of the valve (320) moves again toward the first exhaust port (311) due to the wearer's inhalation, thereby blocking the first exhaust port (311), thereby blocking the inhalation of outside air.

[0146] Accordingly, when the wearer inhales, the first exhaust port (311) of the exhaust part is blocked, preventing harmful external air from being transmitted to the wearer through the exhaust part, and at the same time, oxygen can be supplied from the oxygen generating member (400), thereby safely protecting the wearer's respiratory system from harmful substances generated in industrial sites and having the effect of helping the wearer breathe smoothly.

[0147] In addition, since the partition separator (314) formed in the lower housing (310) is in close contact with the inside of the middle housing (330), the area between the lower housing (310) and the middle housing (330) is partitioned vertically, thereby preventing oxygen generated from the oxygen generating member (400) from leaking out to the outside through the second exhaust port and the third exhaust port formed in the exhaust section, and since the oxygen generated from the oxygen generating member (400) is directly delivered to the wearer through the first and second through holes formed in the upper part of the exhaust section, the efficiency of oxygen supply can be improved.

[0148] That is, the dust mask of the present invention can control the opening and closing of the exhaust section through the wearer's breathing, including the wearer's exhalation and inhalation, and the area within the exhaust section is divided into upper and lower sections through a partition separator, so that the space formed in the upper section can transmit the wearer's exhalation to the oxygen generating member and function as a passage through which the generated oxygen moves, and the space formed in the lower section of the exhaust section can function as a passage through which the wearer's exhalation is discharged to the outside, thereby improving the user's breathing environment and preventing air contamination inside the mask body, and can exhibit the effect of maintaining breathing for a long time without being supplied with separate oxygen from the outside.

[0149] Hereinafter, an industrial dust mask including an oxygen generating member according to another embodiment of the present invention will be described with reference to FIGS. 9 to 13.

[0150] As another embodiment of the present invention, as shown in FIGS. 9 and 10, the exhaust section may be provided with a first housing (500) and a second housing (600).

[0151] At this time, the first housing (500) described above performs the same function as the lower housing (310) described above, and is formed at a location corresponding to one of the positions of the wearer's mouth and nose among the areas of the mask body (100), and a fourth exhaust port (510) penetrating the mask body (100) is formed in an area of ​​the lower portion so that the wearer's exhaled breath is discharged, and may include a valve (520) capable of blocking the fourth exhaust port (510) described above.

[0152] At this time, the fourth exhaust port (510) described above can be understood to perform the same function as the first exhaust port described above, and specifically, the fourth exhaust port (510) is formed with a preset size at a location corresponding to one of the positions of the wearer's mouth and nose among the areas of the mask body (100), and can be configured to have a size of about 1 mm, for example, and can be configured to be formed in multiple numbers to secure a ventilation effect, as illustrated in FIG. 9.

[0153] In addition, the size and number of the fourth exhaust port (510) according to another embodiment of the present invention may be changed and modified as needed, and the present invention is not limited thereto.

[0154] Meanwhile, the above-described valve (520) controls the opening and closing of the above-described fourth exhaust port (510) through the wearer's breathing, and as illustrated in FIG. 9, it is formed to be larger than the area where the fourth exhaust port (510) is formed, and an upper or lower area is fixed to the outer surface of the above-described mask body (100) to block the above-described fourth exhaust port (510), but it can be understood that the area excluding the fixed area is movable according to the wearer's breathing, thereby controlling the opening and closing of the fourth exhaust port (510).

[0155] Specifically, referring to FIG. 12, the valve (520) described above can be configured so that when exhalation occurs from the wearer's mouth and nose, a freely movable portion of the valve (520) relative to a fixed area separates from the fourth exhaust port (510) described above, thereby allowing the exhalation to be discharged through the fourth exhaust port (510), and when inhalation occurs from the wearer's mouth and nose, the valve (520) can block the fourth exhaust port (510) described above, thereby blocking the intake of external air.

[0156] That is, as illustrated in (B) of FIG. 12, the non-fixed portion of the valve (520) moves outward from the mask body (100) in response to the wearer's exhalation, and the valve (520) separates from the fourth exhaust port (510), thereby allowing the wearer's exhalation to be discharged through the fourth exhaust port (510). As illustrated in (A) of FIG. 12, the non-fixed portion of the valve (520) moves again toward the fourth exhaust port (510) in response to the wearer's inhalation, thereby blocking the fourth exhaust port (510), thereby blocking the intake of external air.

[0157] 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 (520) opens through the wearer's exhalation, water vapor and carbon dioxide contained in the wearer's exhalation are discharged through the fourth exhaust port (510), and when the valve (520) blocks the fourth exhaust port (510) through the wearer's inhalation, harmful substances from the outside can be prevented from being inhaled through the fourth exhaust port (510).

[0158] Meanwhile, as another embodiment of the present invention, it is preferable to understand that the above-described valve (520) is formed to correspond to the number of the above-described fourth exhaust ports (510), as shown in FIG. 9, but it is also possible to enable multiple fourth exhaust ports (510) to be opened and closed with one valve (520). In this case, it is preferable to form the valve (520) to a size that can block all of the multiple fourth exhaust ports (510), and the present invention is not limited thereto.

[0159] Meanwhile, the above-described valve (520) can be understood to perform the same function as the valve (320) according to an embodiment of the present invention illustrated in FIG. 8.

[0160] Returning to FIG. 9 and continuing the explanation, the first housing (500) described above may have a first coupling portion (530) formed to which the second housing described later is coupled.

[0161] Specifically, the first connecting portion (530) described above is formed along the outer circumferential surface of the area where the fourth exhaust port (510) and the valve (520) described above are formed, but is formed to be larger than the size of the valve (520), so that an area of ​​the second housing described later can be connected.

[0162] At this time, it is preferable to use a fitting method to connect the first coupling portion (530) described above and an area of ​​the second housing to be described later. However, in addition to the fitting method, any connecting method may be used as long as the second housing to be described later can be connected to the first housing (500) described above, and the present invention is not limited thereto.

[0163] In addition, after the first connecting portion (530) of the first housing (500) described above and the second housing described below are connected, the valve (520) described above moves according to the wearer's exhalation, and the wearer's exhalation moves from the inside of the mask body (100) toward the outside through the opened fourth exhaust port (510) and is simultaneously transmitted to the second housing, whereby oxygen is generated in the second housing.

[0164] Meanwhile, as another embodiment of the present invention, as illustrated in FIGS. 10 to 13, the second housing (600) described above is coupled to the first housing (500) described above, and an accommodation space (610) is formed in an internal region to accommodate an oxygen generating member (400) that generates oxygen through a chemical reaction with water vapor and carbon dioxide generated from the wearer's breathing, and the accommodation space (610) for accommodating the oxygen generating member (400) is formed in an upper region, and a fifth exhaust port (620) is formed in a lower region to discharge the wearer's exhaled breath discharged from the fourth exhaust port (510) of the first housing (500) to the outside, and a through hole (621) penetrating the lower portion of the accommodation space (610) described above and the upper portion of the fifth exhaust port (620) described above may be formed.

[0165] At this time, the second housing (600) described above can be understood to have a similar shape to the shape in which the upper housing and the middle housing are combined according to an embodiment of the present invention as described above. In addition, the fifth exhaust port (620) described above can be understood to perform the function of discharging the wearer's exhalation to the outside, like the second exhaust port and the third exhaust port according to an embodiment of the present invention as described above.

[0166] Meanwhile, the fifth exhaust port (620) described above is formed by penetrating from one side of the second housing (600) adjacent to the first housing (500) to the other side, and as shown in FIGS. 10 and 11, a plurality of exhaust ports can be formed to effectively discharge the wearer's exhalation to the outside.

[0167] In addition, the above-described through hole (621) is formed by penetrating the fifth exhaust port (620) and the receiving space (610) so that the wearer's exhalation, which is discharged through the fourth exhaust port (510) as shown in FIGS. 11 and 12, is transmitted to the receiving space (610) where the oxygen generating member (400) formed at the upper end of the fifth exhaust port (620) is received during the process of being discharged to the outside through the fifth exhaust port (620) of the second housing (600), and can perform the function of a movement path along which a portion of the wearer's exhalation moves.

[0168] Accordingly, it is preferable to understand that the wearer's exhaled breath moves to the oxygen generating member (400) accommodated in the accommodation space (610) through the above-described through-hole (621), and the water vapor and carbon dioxide contained in the wearer's exhaled breath chemically react with the oxygen generating compound (410) in the oxygen generating member (400) to generate oxygen, and the generated oxygen moves again through the through-hole (621) and is delivered toward the wearer's respiratory organ through the fourth exhaust port (510).

[0169] Meanwhile, as another embodiment of the present invention, the second housing (600) described above may include an oxygen generating member insertion part (630) and a second coupling part (640), as shown in FIGS. 11 to 13.

[0170] As shown in FIG. 11, the oxygen generating member insertion part (630) may be formed in one area of ​​the second housing (600), and may be formed at a position corresponding to the receiving space (610) so that the oxygen generating member (400) can be inserted into the receiving space (610) within the second housing (600) from the outside.

[0171] In addition, it is preferable that the oxygen generating member insertion portion (630) described above be formed in a circular shape so that the film-shaped oxygen generating member (400) can be rolled up into a roll shape and inserted. It is preferable to understand that when the oxygen generating member (400) rolled up into a roll shape is inserted into the receiving space (610) in the second housing (600), the oxygen generating member (400) is spread out from the roll shape into a film shape due to the shape restoring force of the oxygen generating member (400) and is fixed in the receiving space (610).

[0172] Meanwhile, it can be understood that the oxygen generating member (400) according to another embodiment of the present invention has the same configuration and function as the oxygen generating member according to the above-described embodiment of the present invention.

[0173] Specifically, the oxygen generating member described above includes an oxygen generating compound (410) and a pouch (420), and the pouch described above can be formed of at least one material selected from the group consisting of Tyvek, elastic non-woven fabric, polyamide, and polyethylene terephthalate.

[0174] At this time, it can be understood that the materials used in the above-described pouch have shape restoring power, so that even if the shape is deformed, it can be restored to its initial shape.

[0175] Accordingly, as illustrated in FIG. 11, when the oxygen generating member (400) rolled into a roll shape is inserted into the oxygen generating member insertion portion (630) formed in the second housing (600), as illustrated in FIG. 12, the oxygen generating member (400) can be fixed to the receiving space (610) in the second housing (600) due to the shape restoring force of the pouch (420) of the oxygen generating member (400) in the receiving space (610) in the second housing (600).

[0176] Accordingly, as another embodiment of the present invention, a film-shaped oxygen generating member (400) having shape restoring power may be rolled into a roll shape and inserted into a second housing (600), and the inserted oxygen generating member (400) may be fixed within the second housing (600) while being restored to a film shape, thereby preventing the oxygen generating member (400) from being detached to the outside.

[0177] Meanwhile, although not shown in the attached drawing, as another embodiment of the present invention, a fixed stopper (not shown) may be further included that can seal the receiving space where the oxygen generating member is received by blocking the oxygen generating member insertion portion formed by penetrating the receiving space where the oxygen generating member is received from an area of ​​the outer surface of the second housing. Specifically, after the oxygen generating member is rolled up and inserted into the oxygen generating member insertion portion described above, a fixed stopper formed in a shape corresponding to the shape of the oxygen generating member insertion portion is inserted into the oxygen generating member insertion portion to seal the receiving space where the oxygen generating member is received, thereby preventing the oxygen generating member from coming off from the receiving space within the second housing and preventing oxygen generated from the oxygen generating member from leaking to the outside.

[0178] Returning to FIG. 12 and continuing the explanation, the second coupling portion (640) described above is formed on one surface of the second housing (600) adjacent to the mask body (100) described above so that the second housing (600) can be coupled to the first housing (500) formed on the mask body (100), and it is preferable to understand that it is formed in a form that can be coupled to and fixed to the first coupling portion (530) of the first housing (500) as illustrated in FIG. 9 and FIG. 12.

[0179] At this time, it is preferable that the second coupling portion (640) described above be coupled by fitting into the first coupling portion (530) as illustrated in FIG. 12, and in addition to the fitting method, any coupling method may be used as long as the second housing (600) is stably coupled to the first housing (500) formed in the mask body (100) and the second housing (600) can be fixed, and the present invention is not limited thereto.

[0180] Hereinafter, with reference to FIGS. 12 and 13, the operation process of the valve according to the transport path of water vapor and carbon dioxide generated through the breathing of a wearer wearing an industrial dust mask including an oxygen generating member according to another embodiment of the present invention and the process of oxygen being generated from an oxygen generating member inserted into a second housing and transferred to the wearer will be described.

[0181] First, according to another embodiment of the present invention, the second housing discharges the wearer's exhaled breath from the fourth exhaust port to the outside through the fifth exhaust port and simultaneously transmits the wearer's exhaled breath to a receiving space where an oxygen generating member is accommodated to generate oxygen, and as the wearer's exhaled breath is discharged to the outside through the fourth exhaust port and the fifth exhaust port, the oxygen generated by the oxygen generating member inserted in the second housing can be supplied to the wearer through the fourth exhaust port due to the low pressure formed in the area between the fourth exhaust port and the fifth exhaust port.

[0182] Specifically, the exhaled breath generated from the wearer's breathing contains water vapor and carbon dioxide, and thus has a high density and temperature. Therefore, as illustrated in (B) of FIG. 12, when the wearer exhales, the valve (520) moves and the fourth exhaust port (510) opens, and when the exhaled breath is discharged through the opened fourth exhaust port (510), the air density inside the mask body (100) and the area between the fourth exhaust port (510) and the fifth exhaust port (620) decreases, the temperature decreases, and a low pressure may be formed.

[0183] To explain in more detail, as illustrated in (B) of FIG. 12, when exhalation is generated from the wearer's mouth and nose, the freely movable portion based on the fixed area of ​​the valve (520) is separated from the fourth exhaust port (510) described above, and the fourth exhaust port (510) is opened, and the exhalation discharged through the opened fourth exhaust port (510) is discharged to the outside through the fifth exhaust port (620) and simultaneously transferred to the oxygen generating member (400) accommodated in the accommodation space (610) through the through hole (621) formed in the second housing (600). It is preferable to understand that in this process, the air density inside the mask body (100) and the area between the fourth exhaust port (510) and the fifth exhaust port (620) decreases, the temperature drops, and a low pressure is formed.

[0184] In addition, it can be understood that the wearer's exhalation is simultaneously discharged through the fourth exhaust port (510) and transferred to the oxygen generating member (400) within the second housing (600), so that water vapor and carbon dioxide contained in the wearer's exhalation are transferred to the oxygen generating member (400), thereby generating oxygen through a chemical reaction between the oxygen generating compound (410) within the oxygen generating member (400) and the water vapor and carbon dioxide.

[0185] Meanwhile, as illustrated in FIG. 13, oxygen generated from the oxygen generating member (400) can be understood to supply oxygen to the wearer by moving from the receiving space (610) where the oxygen generating member (400) is received through the through hole (621) and the fifth exhaust port (620) to the inside of the mask body (100) through the fourth exhaust port (510) due to the low pressure generated in the area between the fourth exhaust port (510) and the fifth exhaust port (620) at the moment the fourth exhaust port (510) is opened and the low pressure formed inside the mask body (100).

[0186] In addition, when oxygen is supplied to the wearer, the wearer inhales oxygen into the body through inhalation, and at the same time, as shown in (A) of FIG. 12, the non-fixed portion of the valve (320) moves again toward the fourth exhaust port (510) to block the fourth exhaust port (510), thereby blocking the inhalation of outside air.

[0187] That is, it is preferable to understand that an industrial dust mask including an oxygen generating member according to another embodiment of the present invention generates oxygen by transmitting the wearer's exhalation to the oxygen generating member through the fourth exhaust port of the first housing formed in the mask body, the fifth exhaust port of the second housing coupled to the first housing, and the through hole, and when the oxygen generated from the oxygen generating member is transmitted to the wearer through the low pressure in the mask body formed by the wearer's exhalation and the low pressure in the area between the fourth exhaust port and the fifth exhaust port, the wearer inhales the transmitted oxygen into the body through inhalation, and at this time, the valve blocks the fourth exhaust port through the wearer's inhalation, thereby preventing external harmful air from being transmitted to the wearer through the fourth exhaust port and the fifth exhaust port.

[0188] According to one embodiment of the present invention comprehensively described above, an industrial dust mask including an oxygen generating member according to the present invention has an effect of allowing the oxygen generating member to be inserted into an exhaust port of the dust mask, thereby discharging the wearer's exhaled breath to the outside through the exhaust port and simultaneously transferring some of the exhaled breath to the oxygen generating member to generate oxygen, and safely protecting the wearer's respiratory organs from harmful substances generated in industrial sites by receiving the oxygen generated from the oxygen generating member again while the wearer inhales, thereby supplying oxygen and helping the wearer breathe smoothly.

[0189] 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.

[0190] In addition, according to one embodiment of the present invention, the oxygen generating member has the effect of helping to remove coronavirus, sterilize, antibacterial, deodorize, provide fragrance, and supply oxygen.

[0191] Accordingly, by applying an oxygen generating member according to an embodiment of the present invention to a dust mask, it is possible to provide effects such as blocking harmful substances generated in industrial sites, removing coronavirus, sterilizing, antibacterial, and deodorizing, and supplying fragrance and oxygen to a wearer wearing the dust mask.

[0192] In addition, according to one embodiment of the present invention, by providing an oxygen generating member in a film form, the size of an exhaust portion into which the oxygen generating member is inserted can be effectively reduced, thereby providing convenience to the wearer in using the dust mask.

[0193] In addition, according to one embodiment of the present invention, by dividing an area within an exhaust section into upper and lower sections through a partition, a portion of the wearer's exhaled breath is transferred to an oxygen generating member through a first hole and a second hole formed in an upper section of the exhaust section, and the remaining exhaled breath is discharged to the outside through the first to third exhaust ports formed in a lower section of the exhaust section, thereby controlling the amount of the wearer's exhaled breath transferred to the oxygen generating member, thereby improving the efficiency of oxygen generation generated from the oxygen generating member, and improving the wearer's breathing environment and preventing air contamination inside the mask body.

[0194] In addition, according to one embodiment of the present invention, by dividing the area within the exhaust section into upper and lower sections, oxygen generated from the oxygen generating member is directly delivered to the wearer through the first and second holes formed in the upper portion of the exhaust section, thereby preventing oxygen from leaking out, thereby effectively supplying oxygen to the wearer.

[0195] Although the industrial dust mask including the oxygen patch 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 of the present invention.

[0196] 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.
