Description

Technical Field

[0001] The present invention relates to a dust-proof mask capable of blocking harmful substances generated in industrial sites. Specifically, the present invention relates to an industrial dust-proof mask provided with an oxygen-generating member, which is configured such that the oxygen-generating member is inserted into the exhaust portion of the dust-proof mask. Through this configuration, when the wearer's exhaled air is discharged to the outside through the exhaust portion, a part of the exhaled air is simultaneously supplied to the oxygen-generating member to generate oxygen, and when the wearer inhales, the oxygen generated from the oxygen-generating member is supplied. Thereby, the wearer's respiratory organs can be safely protected from harmful substances generated at industrial sites, and oxygen can be supplied to smoothly assist the wearer's breathing.

Background Art

[0002] Generally, a dust-proof mask is worn on the face by workers working in industrial sites where dust is generated, and is a protective device for protecting the worker's health by blocking dust generated during work from flowing into the body through the mouth and nose.

[0003] Such a conventional dust-proof mask is composed of a mask body having a shape covering the mouth and nose, an air intake port installed on both sides of the mask body with a built-in filter, an exhaust port installed on the lower middle side of the mask body, and a fixing member connected to the mask body by a band and fixed to the head so as to bring the mask body into close contact with the face.

[0004] When working while wearing the above-mentioned dust-proof mask on the face, it covers the mouth and nose and enables breathing through the mouth and nose via the air intake port and the exhaust port, thereby preventing harmful substances generated during work from flowing into the body through the mouth and nose.

[0005] However, with conventional dust masks, the pressure in the space between the mask and the wearer's face increases rapidly when the wearer exhales, causing the mask to lift away from the face and expel air. At this time, the exhaled air expelled from the upper part of the mask, i.e., the nose area, can fog up the safety glasses of the wearer, obstructing their vision and creating a dangerous situation that increases the risk of safety accidents.

[0006] Therefore, as an attempt to solve the above problems, Korean Registered Patent No. 10-1692949 discloses a dust mask technology that prevents glasses from fogging up by guiding exhaled air, which is exhausted to the upper side of the mask body, to the lower side of the mask through a separate space inside the mask and expelling it quickly.

[0007] However, while the aforementioned prior art has the advantage of preventing fogging by guiding the wearer's exhaled breath to the bottom of the mask and preventing it from being expelled from the top, the mask is tightly fitted to the wearer's face, which can hinder oxygen supply and potentially cause problems when wearing the mask for extended periods to breathe.

[0008] [Patent Document 1] Korean Registered Patent Publication No. 10-1692949 [Overview of the Initiative] [Problems that the invention aims to solve]

[0009] The present invention was created to solve the above-mentioned problems, and aims to provide an industrial dust mask that safely protects the wearer's respiratory system from harmful substances generated in industrial sites and also assists the wearer's breathing by supplying oxygen. This is achieved by configuring the dust mask so that an oxygen generating member is inserted into the exhaust port, thereby expelling the wearer's exhaled breath to the outside through the exhaust port, while simultaneously supplying a portion of the exhaled breath to the oxygen generating member to generate oxygen, and then supplying the oxygen generated from the oxygen generating member again when the wearer inhales. [Means for solving the problem]

[0010] To achieve the above objective, an industrial dust mask equipped with an oxygen generating member according to one embodiment of the present invention comprises: a mask body; a fixing band for fixing the mask body to the wearer's face; an exhaust section formed in one area of ​​the outer surface of the mask body, having an exhaust port for expelling the wearer's exhaled breath to the outside; and an oxygen generating member inserted into one area of ​​the exhaust section, which generates oxygen by undergoing a chemical reaction upon receiving water vapor and carbon dioxide generated from the wearer's respiration. Herein, through holes are formed that penetrate the mask body and one area of ​​the exhaust section, and a portion of the wearer's exhaled breath expelled to the outside through the exhaust port of the exhaust section is supplied to the oxygen generating member inserted into the exhaust section through the through holes to generate oxygen, and the oxygen generated from the oxygen generating member is supplied to the wearer through the through holes when inhalation occurs from the wearer's mouth and nose.

[0011] The exhaust section is formed in a location within the area of ​​the mask body corresponding to either the wearer's mouth or nose, and includes a lower housing with a first exhaust port formed in one area of ​​the lower end that penetrates the mask body, and a first through hole formed in one area of ​​the upper end that penetrates the mask body, and a valve membrane which is larger than the first exhaust port and has a hole formed in one area of ​​the upper end that is fixed to a protruding part of the lower housing so as to block the first exhaust port, with the hole being inserted and fixed to the fixing part, and the area excluding the fixed area being movable in accordance with the wearer's breathing, and is connected to the lower housing and includes one area on both sides and the lower end The present invention includes an upper housing in which a second exhaust port is formed in one region for expelling the wearer's exhaled breath to the outside, and an intermediate housing which is inserted inside the upper housing after the oxygen generating member is inserted into the upper housing to fix the oxygen generating member, a second through hole is formed at a position corresponding to the first through hole, a third exhaust port is formed in one region on both sides and one region at the lower end in a shape corresponding to the second exhaust port, and a valve fixing portion is formed to protrude from one region on the lower surface to fix the upper end of the valve, wherein when the intermediate housing is connected to the upper housing, it is preferable that the second exhaust port and the third exhaust port are arranged on the same line.

[0012] The lower housing is provided with a partition separation portion that protrudes from a region on the upper surface of the lower housing and is formed in the region between the first through hole and the fixing portion. When the upper housing, into which the intermediate housing is inserted, is connected to the lower housing, it is preferable that the protruding tip of the partition separation portion comes into close contact with the lower end of the second through hole formed in the intermediate housing, thereby partitioning the region between the lower housing and the intermediate housing vertically.

[0013] Preferably, the first through-hole and the second through-hole are arranged in a straight line so that when exhalation occurs from the wearer's mouth and nose, a portion of the exhaled air is supplied from inside the mask body through the first through-hole and the second through-hole to the oxygen generating member, and when inhalation occurs from the wearer's mouth and nose, the oxygen generated from the oxygen generating member is supplied to the wearer inside the mask body through the second through-hole and the first through-hole.

[0014] Preferably, the lower housing has a protrusion and a coupling groove formed along its outer circumferential surface, and the upper housing has a coupling projection formed at its lower end that is inserted into the coupling groove. When the coupling projection of the upper housing is inserted into the coupling groove of the lower housing, the lower end of the intermediate housing inserted into the upper housing comes into close contact with the upper surface of the protrusion, and the lower end of the upper housing is fitted into the protrusion, thereby coupling the lower housing, the valve, the intermediate housing, the oxygen generating member, and the upper housing in that order to form the exhaust section containing the oxygen generating member.

[0015] The valve is configured such that when exhalation occurs from the wearer's mouth and nose, a portion of the valve that is freely movable relative to a fixed area of ​​the valve moves away from the first exhaust port, allowing exhaled air 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 to block the intake of outside air, and it is preferable that the exhaled air discharged through the first exhaust port is discharged to the outside through the second and third exhaust ports.

[0016] Preferably, the oxygen generating member comprises an oxygen generating compound that reacts with a reactant containing at least one of water vapor and carbon dioxide to generate oxygen, and a pouch formed in the shape of a film of a set size, in which the oxygen generating compound is contained.

[0017] The oxygen-generating compound is preferably formed by mixing an oxidizing agent containing at least one of potassium superoxide and sodium peroxide, a stabilizer containing at least one of calcium hydroxide, aluminum hydroxide, and magnesium hydroxide, silica gel, and carrageenan in a set ratio.

[0018] The pouch is preferably made of at least one of the following materials: Tyvek, elastic nonwoven fabric, polyamide, and polyethylene terephthalate. [Effects of the Invention]

[0019] The industrial dust mask equipped with an oxygen generating member according to the present invention is configured such that the oxygen generating member is inserted into the exhaust port of the dust mask. This configuration allows the wearer's exhaled breath to be expelled to the outside through the exhaust port, while simultaneously supplying a portion of the exhaled breath to the oxygen generating member to generate oxygen. When the wearer inhales, the oxygen generated from the oxygen generating member is supplied again, thereby safely protecting the wearer's respiratory system from harmful substances generated in industrial settings and assisting the wearer's breathing smoothly by supplying oxygen.

[0020] Furthermore, 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 that constitutes the oxygen generating member, the moisture generated during the oxygen generation process of the oxygen generating compound is absorbed, thereby preventing low-temperature burns caused by such moisture.

[0021] Furthermore, according to one embodiment of the present invention, the oxygen generating component has the effect of assisting in the removal of coronavirus, sterilization, antibacterial action, deodorization, fragrance, and oxygen supply.

[0022] Accordingly, by applying an oxygen generating member according to one 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, sterilization, antibacterial properties, and deodorization, and to supply fragrance and oxygen to the wearer of the dust mask.

[0023] Further, according to one embodiment of the present invention, providing the oxygen generating member in a film form can effectively reduce the size of the exhaust part into which the oxygen generating member is inserted, and has the effect of providing convenience for a wearer when using a dust-proof mask.

[0024] Further, according to one embodiment of the present invention, the region inside the exhaust part is vertically partitioned via the partition separation part, such that part of the wearer's exhaled air is supplied to the oxygen generating member through the first through hole and the second through hole formed at the upper end of the exhaust part, and the remaining exhaled air is discharged to the outside through the first to third exhaust ports formed at the lower end of the exhaust part. With this configuration, the amount of the wearer's exhaled air supplied to the oxygen generating member can be adjusted to improve oxygen generation efficiency, thereby improving the wearer's breathing environment and preventing air pollution inside the mask body.

[0025] Furthermore, according to one embodiment of the present invention, by vertically partitioning the region inside the exhaust part, oxygen generated by the oxygen generating member is directly supplied to the wearer through the first through hole and the second through hole formed at the upper end of the exhaust part, thereby preventing oxygen from leaking to the outside and effectively supplying oxygen to the wearer.

[0032] The present invention relates to an industrial dust mask equipped with an oxygen generating member. Specifically, the present invention aims to provide an industrial dust mask that safely protects the wearer's respiratory system from harmful substances generated in industrial sites and also assists the wearer's breathing by supplying oxygen. This is achieved by configuring the dust mask so that the oxygen generating member is inserted into the exhaust port, thereby expelling the wearer's exhaled breath to the outside through the exhaust port, while simultaneously supplying a portion of the exhaled breath to the oxygen generating member to generate oxygen, and then supplying the oxygen generated from the oxygen generating member again when the wearer inhales.

[0033] For a more detailed explanation, the present invention will be described below with reference to the attached drawings, and multiple drawings may be referenced simultaneously to explain a single technical feature and component of the invention.

[0034] To illustrate the present invention, the attached drawings provide a schematic overview. Figure 1 shows a schematic example of the shape of an industrial dust mask equipped with an oxygen generating member according to one embodiment of the present invention. Figure 2 shows an exploded view of the exhaust section according to one embodiment of the present invention. Figure 3 shows a schematic example of the shape of the lower housing according to one embodiment of the present invention.

Figures 7 and 8 show side cross-sectional views of an industrial dust mask equipped with an oxygen generating member according to one embodiment of the present invention. Figures 9 to 13 show examples of industrial dust masks equipped with an oxygen generating member according to other embodiments of the present invention.

[0035] In the following description, some components shown in the drawings are omitted or excessively enlarged or reduced in order to explain the function of each component of the present invention. However, it should be understood that these illustrated components do not limit the technical features or scope of rights of the present invention.

[0036] Referring to Figure 1, which shows the schematic shape of an industrial dust mask equipped with an oxygen generating member according to one embodiment of the present invention, and Figure 2, which shows an exploded view of the exhaust section, the industrial dust mask equipped with an oxygen generating member according to the present invention is broadly composed of a mask body (100), a fixing band (200), an exhaust section (300), and an oxygen generating member (400).

[0037] First, the mask body (100) constitutes the overall external shape of the industrial dust mask equipped with the oxygen generating member of the present invention (hereinafter referred to as "the dust mask of the present invention"), and can be formed in a shape that simultaneously shields the wearer's mouth and nose.

[0038] In this case, the mask body (100) may be configured to have a variety of materials and structures in accordance with the standards for industrial dust masks, which are classified into special grade, grade 1, and grade 2 according to collection efficiency, leakage rate, etc. In the following description, the mask body (100) may be configured to basically include any known form of mask shape and material, and the present invention is not limited thereto.

[0039] Furthermore, in the present invention, it is preferable to understand that, among facial filtration type and separate type dust masks, an exhaust valve type dust mask is formed in the facial filtration type dust mask.

[0040] On the other hand, a nose rest portion (110) may be formed at the upper end of the mask body (100) in a shape corresponding to the wearer's nose bridge, and it is preferable that the nose rest portion (110) be made of a wire that can be deformed in shape.

[0041] This is to ensure that the mask body (100) fits snugly against the wearer's nose bridge by bending the nose rest portion (110) to conform to the shape of the wearer's nose bridge.

[0042] On the other hand, although not shown in the attached drawings, in 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.

[0043] In this case, the silicone portion can function to adhere closely to the wearer's skin when the mask is worn, effectively blocking outside air. Furthermore, by forming the silicone portion using an elastic silicone material, when the wearer wears the mask, the silicone portion adheres tightly to the contours of the wearer's face without any gaps, fundamentally blocking outside air or external contaminants from entering between the mask and the wearer's face.

[0044] Returning to Figure 1 and continuing the explanation, fixing bands (200) may be formed on both the left and right sides of the mask body (100). The fixing bands (200) are members for fixing the mask body to the wearer's face, and it is preferable that they be formed in a shape that surrounds the wearer's head so that they do not easily separate from the wearer's face.

[0045] In this case, the fixing band (200) can be manufactured using an elastic fiber member, and has the effect of being able to be stretched and adjusted according to the size of the wearer's head, providing a soft and comfortable fit.

[0046] Furthermore, while the fixing band (200) can be made of an elastic rubber material, the present invention is not limited to using a rubber band or any other material that is elastic and easily adjustable in length.

[0047] On the other hand, although not shown in the attached drawings, in another embodiment of the present invention, the fixing band (200) may further include a length adjustment part (not shown), and may be formed to have a structure that allows the length of the fixing band to be adjusted. In this case, the length adjustment part performs the function of finely adjusting the length of the fixing band to match the wearer's head circumference, and can exert the effect of fixing the dust mask of the present invention to the wearer's face more stably.

[0048] On the other hand, as one embodiment of the present invention, the attached drawings illustrate a fixing band (200) in which the aforementioned fixing band (200) surrounds the wearer's head. However, it is also possible to use fixing bands that hook over the ears, and the present invention is not limited to this.

[0049] In another embodiment of the present invention, when the aforementioned fixing band is used as a fixing band that hooks over the ears, the functions of adjusting the length of the fixing band and improving the fit can be performed via an additional structure such as a hook. This is achieved by positioning the hook on the back of the wearer's head and connecting the hook to the fixing bands formed at both ends of the mask body (100) to secure it so as to surround the wearer's head, thereby improving the fit and reducing the burden on the wearer's ears when wearing the dust mask of the present invention for a long period of time.

[0050] On the other hand, the mask body (100) may have an exhaust section (300) formed therein.

[0051] As shown in Figures 1 to 6, the exhaust section (300) is formed in a region of the outer surface of the mask body (100), and an exhaust port may be formed to expel the wearer's exhaled breath to the outside.

[0052] In this case, the exhaust section (300) may include a lower housing (310), a valve (320), an intermediate housing (330), and an upper housing (340).

[0053] On the other hand, multiple exhaust ports may be formed in the exhaust section (300) to perform the function of expelling the wearer's exhaled breath. For example, these may include a first exhaust port (311) formed in the lower housing (310) that constitutes the exhaust section (300), a third exhaust port (332) formed in the intermediate housing (330), and a second exhaust port (341) formed in the upper housing (340).

[0054] First, regarding the lower housing (310), it is formed in a location within the area of ​​the mask body (100) that corresponds to either the mouth or nose of the wearer. A first exhaust port (311) that penetrates the mask body (100) is formed in one area of ​​the lower end of the lower housing (310), and a first through hole (315) that penetrates the mask body (100) may be formed in one area of ​​the upper end.

[0055] In this case, the first exhaust port (311) is preferably formed close to the wearer's mouth in order to effectively expel the wearer's exhaled breath. Specifically, as shown in Figure 3, it is preferably formed in a circular shape of a set size (for example, 1.5 to 2.5 cm in diameter) in a region of the lower end of the lower housing (310), and most preferably in a circular shape with a diameter of 2 cm.

[0056] On the other hand, Figure 3 shows a first exhaust port (311) having a circular shape as an embodiment of the present invention, but the first exhaust port (311) can be modified and implemented in various polygonal shapes other than circular, such as squares and pentagons, and the present invention is not limited thereto.

[0057] On the other hand, a fixing portion (312) may be formed at the upper end of the first exhaust port (311) formed in the lower housing (310).

[0058] The aforementioned fixing portion (312) is formed to protrude from a region of the lower housing (310) in order to fix the valve diaphragm, which will be described later. As shown in Figure 3, it is formed at the upper end of the first exhaust port (311), and multiple such portions may be formed within the diameter range of the first exhaust port (311).

[0059] Therefore, by connecting one region of the valve membrane to the fixing portion (312), one region of the valve membrane is fixed to the lower housing (310).

[0060] On the other hand, the first through-hole (315), as shown in Figures 3 and 4, is formed at the upper end of the lower housing (310) and penetrates the mask body, so it can be understood as a passage through which some of the exhaled breath generated by the wearer wearing the mask body can travel.

[0061] In this case, it is preferable that the first through-hole (315) be provided in multiple locations, as shown in Figures 3 and 4, but it is also possible to form it as a single hole, and its shape and size can be changed as needed, and the present invention is not limited thereto.

[0062] On the other hand, referring to Figure 4, the valve (320) is formed to be larger than the first exhaust port (311), and a hole (321) is formed in one region of its upper end. The valve (320) is installed to block the first exhaust port (311) by inserting and fixing the hole (321) into a fixing portion (312) that protrudes from one region of the lower housing (310). Here, the region excluding the fixed region is movable in accordance with the wearer's breathing and can be understood as controlling the opening and closing of the first exhaust port (311).

[0063] Furthermore, the valve membrane (320) is formed to be larger than the size of the first exhaust port (311), so that it can function to completely block the first exhaust port (311), and holes (321) corresponding to the cross-sectional shape and number of the fixing part (312) are formed so that it can be inserted and fixed into the fixing part (312).

[0064] In this case, when exhalation occurs from the wearer's mouth and nose, the valve (320) is configured such that a portion of the valve (320) that is freely movable relative to a fixed area of ​​the valve (320) moves away from the first exhaust port (311), thereby allowing the exhaled air to be discharged through the first exhaust port (311). Furthermore, when inhalation occurs from the wearer's mouth and nose, the valve (320) can be configured to block the first exhaust port (311), thereby blocking the intake of outside air.

[0065] The exhaled air discharged through the first exhaust port (311) is then discharged to the outside through the second exhaust port formed in the upper housing (described later) and the third exhaust port formed in the intermediate housing (described later).

[0066] Specifically, as shown in Figure 7(b), as the wearer exhales, the valve (320) moves outward from the mask body (100) and the first exhaust port (311), with the unfixed lower end moving relative to the fixed upper end. This causes the valve (320) to separate from the first exhaust port (311), and the wearer's exhaled air is expelled from inside the mask body (100) to the first exhaust port (311). Furthermore, as the wearer inhales, as shown in Figure 7(a), the unfixed lower end of the valve (320) moves again toward the first exhaust port (311), blocking the first exhaust port (311) and thus preventing the inhalation of outside air.

[0067] In other words, exhalation is the air expelled from the wearer and moving to the outside, and inhalation is the process by which the wearer inhales outside air. Therefore, when the valve (320) is opened by the wearer's exhalation, water vapor and carbon dioxide contained in the wearer's exhalation are expelled through the first exhaust port (311). On the other hand, when the valve (320) closes the first exhaust port (311) by the wearer's inhalation, it is possible to prevent harmful substances from the outside from being inhaled through the first exhaust port (311).

[0068] Furthermore, although not shown in Figure 7, it is preferable that the wearer's exhaled breath discharged through the first exhaust port (311) is discharged to the outside through a third exhaust port formed in the intermediate housing (330) and a second exhaust port formed in the upper housing (340).

[0069] On the other hand, as shown in Figure 3, a cross-shaped support (3111) may be formed inside the first exhaust port (311). In this case, the support (3111) can be understood to perform the function of preventing the valve (320) from being drawn into the mask body as the wearer breathes.

[0070] Here, the shape of the support (3111) can be modified and changed to any shape that does not hinder the function of the first exhaust port (311), which is formed to allow the movement of exhaled breath generated by the wearer and oxygen generated by the oxygen generating member described later and supplied to the wearer, and the present invention is not limited thereto.

[0071] Returning to Figure 2 and continuing the explanation, after the valve membrane (320) is fixed to the lower housing, the upper housing (340), into which the oxygen generating member (400) and intermediate housing (330) are inserted, can be connected to the lower housing (310) to form a single exhaust section (300).

[0072] In this configuration, the upper housing (340) is coupled to the lower housing (310), as shown in Figures 1 and 2, and a second exhaust port (341) for expelling the wearer's exhaled breath to the outside may be formed in one area on each side and one area at the lower end.

[0073] On the other hand, an oxygen generating member (400) can be inserted into the upper housing (340), and after the oxygen generating member (400) is inserted, the intermediate housing (330) can be inserted to fix the oxygen generating member (400) to the upper housing (340).

[0074] Specifically, as shown in Figure 2, the intermediate housing (330) is inserted inside the upper housing (340) after the oxygen generating member (400) is inserted into the upper housing (340) to fix the oxygen generating member (400). As shown in Figure 5, the intermediate housing (330) has a second through hole (331) at a position corresponding to the first through hole (315) of the lower housing (310), and a third exhaust port (332) with a shape corresponding to the second exhaust port (341) of the upper housing (340) is formed in one area on both sides and one area at the lower end, and a valve fixing portion (333) is formed to protrude from one area on the lower surface to fix the upper end of the valve (320).

[0075] In this case, when connecting the intermediate housing (330) 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 intermediate housing (330) be positioned on the same line.

[0076] Specifically, the third exhaust port (332) of the intermediate housing (330) is formed in a shape corresponding to the shape of the second exhaust port (341) of the upper housing (340). These are arranged on the same line to form a single passage, and when exhaled air is expelled from the wearer wearing the mask body through the first exhaust port (311) formed through the mask body and the lower housing (310), it is expelled to the outside through the third exhaust port (332) and the second exhaust port (341).

[0077] Therefore, in order to facilitate the expulsion of the wearer's exhaled breath, it is preferable that the shape and position of the second exhaust port (341) and the third exhaust port (332) be formed to correspond to each other.

[0078] On the other hand, as one embodiment of the present invention, the attached drawings specifically show a second exhaust port and a third exhaust port having a hexagonal shape. However, the present invention is not limited to these, and can be implemented with other polygonal shapes including squares and pentagons, or even circular shapes, by appropriate modifications and changes.

[0079] On the other hand, the second through-hole (331) formed in the intermediate housing (330) is formed at the upper end of the intermediate housing (330), as shown in Figure 2, and penetrates the intermediate housing (330). The second through-hole (331) is formed in a number and shape corresponding to the first through-hole (315) of the lower housing (310), so that some of the exhaled breath generated by the wearer wearing the mask body flows into the first through-hole (315), passes through the second through-hole (331), and is supplied to the oxygen generating member (400) inserted between the upper housing (340) and the intermediate housing (330).

[0080] In this case, it is preferable that the second through-hole (331) be provided in multiple locations, as shown in Figure 2, but it is also possible to form it as a single hole, and its shape and size can be changed as needed, and the present invention is not limited thereto.

[0081] Returning to Figure 5 and continuing the explanation, the valve fixing portion (333) formed on the intermediate housing (330) may be formed in a T-shape. It is preferable that this is understood to stably fix the upper end of the valve fixing portion (320) by the upper end of the valve fixing portion (333) vertically fixing the upper end of the valve (320) and the lower end of the valve fixing portion (333) contacting a region of the support (3111) formed on the first exhaust port (311).

[0082] On the other hand, as shown in Figure 2, the oxygen generating member (400) is inserted into a region within the exhaust section and can generate oxygen by undergoing a chemical reaction upon receiving water vapor and carbon dioxide generated from the wearer's respiration.

[0083] Specifically, through-holes are formed that penetrate a region of the mask body (100) and the exhaust section (300). As a result, a portion of the wearer's exhaled breath, which is expelled to the outside through the exhaust port of the exhaust section (300), is supplied to an oxygen generating member (400) inserted into the exhaust section through the through-holes, generating oxygen. The oxygen generated from the oxygen generating member (400) is then supplied back to the wearer through the through-holes when inhalation occurs through the wearer's mouth and nose.

[0084] In this case, the through-hole may include a first through-hole (315) formed in the lower housing (310) and a second through-hole (331) formed in the intermediate housing (330), as described above.

[0085] On the other hand, in one embodiment of the present invention, the first through hole (315) formed in the lower housing (310) and the second through hole (331) formed in the intermediate housing (330) are arranged to be aligned in a straight line. This allows a portion of the exhaled air to be supplied from inside the mask body to the oxygen generating member (400) via the first through hole (315) and the second through hole (331) when exhaled air is produced from the wearer's mouth and nose, and allows oxygen generated from the oxygen generating member (400) to be supplied to the wearer inside the mask body via the second through hole (331) and the first through hole (315) when inhaled air is produced from the wearer's mouth and nose.

[0086] More specifically, the oxygen generating member (400) is inserted between the upper housing (340) and the intermediate housing (330) of the exhaust section. It then receives a portion of the exhaled breath from the wearer wearing the mask through a first through-hole (315) formed in the lower housing (310) of the exhaust section and a second through-hole (331) formed in the intermediate housing (330). This causes a chemical reaction with the water vapor and carbon dioxide contained in the exhaled breath to generate oxygen, which is then supplied back to the wearer through the second through-hole (331) and the first through-hole (315) when the wearer inhales.

[0087] On the other hand, the oxygen generating member (400) is fixed in place by being inserted between the upper housing (340) and the intermediate housing (330) so as not to detach to the outside, and is configured to maintain a sealed state except for the area adjacent to the second through hole (331) formed in the intermediate housing (330). This prevents contact with external water vapor and carbon dioxide other than the wearer's exhaled breath, prevents the generation of more oxygen than necessary, and thus prevents the wearer from experiencing side effects such as hyperventilation, oxygen toxicity, headache, and dizziness.

[0088] Returning to Figures 3 and 4 to continue the explanation, the aforementioned lower housing (310) may include a compartment separator (314) for dividing the area within the exhaust section vertically.

[0089] Specifically, the compartment separation portion (314) can be understood as being formed to protrude from a region on the upper surface of the lower housing (310) and to be formed in the region between the first through hole (315) and the fixing portion (312).

[0090] Therefore, in one embodiment of the present invention, when connecting an upper housing (340) in which an intermediate housing (330) is inserted inside to a lower housing (310), the partition separation portion (314), as shown in Figure 7, has a protruding tip that comes into close contact with the lower end of a second through hole (331) formed in the intermediate housing (330), and can perform the function of partitioning the area between the lower housing (310) and the intermediate housing (330) vertically.

[0091] At this time, as the area between the lower housing (310) and the intermediate housing (330) is divided vertically via the compartment separation section (314), a portion of the wearer's exhaled breath is supplied to the oxygen generating member (400) through the first through-hole (315) and the second through-hole (331) formed at the upper end of the exhaust section, and the remaining exhaled breath is discharged to the outside through the first to third exhaust ports formed at the lower end of the exhaust section. This allows for adjustment of the amount of exhaled breath supplied to the oxygen generating member (400), thereby improving the oxygen generation efficiency of the oxygen generating member (400), improving the breathing environment of the wearer wearing the dust mask of the present invention, and preventing air contamination inside the mask body (100).

[0092] Furthermore, by dividing the area within the exhaust section into upper and lower sections, the oxygen generated from the oxygen generating member (400) is directly supplied to the wearer through the first through-hole (315) and the second through-hole (331) formed at the upper end of the exhaust section. This prevents oxygen from leaking to the outside and effectively supplies oxygen to the wearer.

[0093] On the other hand, referring to Figures 2, 3, and 6 simultaneously, the lower housing (310) may have a projection (313) and a coupling groove (3131) formed along its outer peripheral surface, and the upper housing (340) may have a coupling projection (342) formed at its lower end, which is inserted into the coupling groove (3131).

[0094] Therefore, as the coupling projection (342) of the upper housing (340) is inserted into the coupling groove (3131) of the lower housing (310), the lower end of the intermediate housing (330) inserted inside the upper housing (340) comes into close contact with the upper surface of the projection (313), and the lower end of the upper housing (340) is fitted into the projection (313), thereby forming an exhaust section.

[0095] In this configuration, the valve membrane (320) is located between the lower housing (310) and the intermediate housing (330), the first exhaust port (311) is located on the back of the valve membrane (320), and the oxygen generating member (400) is located between the intermediate housing (330) and the upper housing (340).

[0096] In other words, as shown in Figure 2, the lower housing (310), the valve (320), the intermediate housing (330), the oxygen generating member (400), and the upper housing (340) are sequentially joined together to form an exhaust section (300) containing the oxygen generating member (400) of the present invention.

[0097] On the other hand, referring simultaneously to Figures 7 and 8, the oxygen generating member (400) 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).

[0098] On the other hand, the 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 more of calcium hydroxide (Ca(OH)2), aluminum hydroxide (Al(OH)3), and magnesium hydroxide (Mg(OH)2), silica gel and carrageenan in a set ratio.

[0099] At this time, potassium superoxide exists as a yellow solid and is produced when potassium is heated for a long time in a glass tube while dry air is passed through it. Potassium superoxide reacts with water to release oxygen and produce potassium hydroxide (KOH) (see reaction equation 1), which is known as a strong oxidizing agent.

[0100]

number

[0101] The aforementioned sodium peroxide exists as yellowish-white granules or powder, and is also called sodium peroxide or sodium dioxide. It reacts with water to produce sodium hydroxide (NaOH) and oxygen (see reaction equation 2), and performs its function as an oxidizing agent.

[0102]

number

[0103] On the other hand, potassium superoxide can react with carbon dioxide to release oxygen and produce potassium carbonate (see reaction equation 3), and sodium peroxide can react with carbon dioxide to release oxygen and produce sodium carbonate (see reaction equation 4).

[0104]

number

[0105]

number

[0106] Therefore, in the present invention, it is preferable to understand that the oxygen generating compound (410) reacts with a reactant containing at least one of water vapor (H2O) and carbon dioxide (CO2) generated from the wearer's respiration to generate oxygen.

[0107] On the other hand, the oxygen-generating compound (410) in the present invention includes one or more selected alkaline earth metal hydroxides as stabilizers to stabilize the reactivity when potassium superoxide and sodium peroxide, which are oxidizing agents, react with the reactants. These stabilizers consist of alkaline earth metal hydroxides.

[0108] At this time, calcium hydroxide is a white powdery basic compound that is poorly soluble in water, with only about 0.82 g dissolving in 1 liter of water, but it has the characteristic of having a high degree of ionization (dissociation). For this reason, calcium hydroxide dissolved in water exhibits a strong basicity of about pH 12.5.

[0109] On the other hand, when calcium hydroxide reacts with carbon dioxide (CO2), it produces calcium carbonate (see reaction equation 5) via the following reaction equation. The calcium carbonate thus produced can react with carbon dioxide and moisture contained in the air or human breath to be converted into calcium bicarbonate (see reaction equation 6), and can therefore be usefully used to treat carbon dioxide.

[0110]

[0111]

number

[0112] On the other hand, aluminum hydroxide is an amphoteric hydroxide, and when it reacts with an acid, it produces an aluminum salt, and when it reacts with an alkali, it produces an aluminate. In particular, when it comes into contact with water for a long time, it gels, and the gelled aluminum hydroxide exhibits the characteristic of having strong adsorption properties.

[0113] Furthermore, magnesium hydroxide exists in nature as talc, and when magnesium salts are reacted with alkali hydroxide, it is produced as a colorless colloidal precipitate. In addition, when the solid is left in the air, it can absorb carbon dioxide and release it as magnesium carbonate, so it can be usefully used in the treatment of carbon dioxide.

[0114] On the other hand, the oxygen-generating compound (410) in the present invention may include hygroscopic silica gel and carrageenan to absorb the moisture produced when oxygen is generated through a chemical reaction between the oxidizing agent and stabilizer constituting the oxygen-generating compound (410) and a reactant containing at least one of water vapor (H2O) and carbon dioxide (CO2) generated from the wearer's respiration.

[0115] In this case, the silica gel is a glossy, granular, porous material mainly composed of silicon dioxide (SiO2), and due to its porous structure, its surface area is approximately 800 m². 2 It has a very wide absorption rate ( / g) and is characterized by its excellent moisture absorption effect. The fine pores on the surface of silica gel provide spaces that can absorb moisture, and it performs the function of adsorbing moisture from the air.

[0116] Furthermore, carrageenan is a polysaccharide extracted from red algae (seaweed that inhabits coastal waters and is red or purple in color), and is widely used as a thickener, stabilizer, and gelling agent. Carrageenan has the property of gelling when it absorbs moisture, and can perform the function of retaining moisture and preventing its excretion.

[0117] Therefore, the oxygen-generating compound (410) of the present invention, by containing silica gel and carrageenan which absorb moisture, can exhibit the effect of preventing low-temperature burns caused by moisture generated through a chemical reaction between the oxygen-generating compound (410) and a reactant containing at least one of water vapor (H2O) and carbon dioxide (CO2).

[0118] On the other hand, the pouch (420) is formed in the shape of a film of a set size and contains the oxygen-generating compound (410) inside, and can be made of at least one of the following materials: Tyvek, elastic nonwoven fabric, polyamide, and polyethylene terephthalate.

[0119] In this case, it is preferable that the pouch (420) is made of a material with excellent porosity so that water vapor and carbon dioxide contained in the wearer's exhaled breath are supplied to the oxygen-generating compound (410) inside the pouch (420), and the oxygen generated from the oxygen-generating compound (410) is discharged to the outside of the pouch (420).

[0120] On the other hand, the material used to form the pouch (420) is described in detail as follows.

[0121] Tyvek is a synthetic material made from high-density polyethylene fibers that are bonded without a binder, resulting in the formation of microscopic pores. This provides excellent breathability, allowing water vapor to penetrate the material while preventing water and other liquids from passing through. It also has a continuous structure of long fibers that provides a microbial barrier function, effectively blocking harmful substances such as asbestos, mold, glass fibers, and lead, and possesses strong durability and high resilience.

[0122] Furthermore, elastic nonwoven fabrics are formed by applying a thin film of an elastic polymer coating agent to part or all of one surface of an stretchable nonwoven fabric, thereby creating an elastic nonwoven mesh on the surface of the nonwoven fabric, which has the effect of having excellent stretchability and recovery rate.

[0123] Polyamides are thermosetting or thermoplastic amorphous polymers with excellent mechanical, thermal, and chemical resistance, making them suitable for use in a variety of applications, including textiles, films, and electrical insulators. In particular, when used as textiles, their high durability, chemical stability, and elasticity make them ideal for clothing and industrial materials.

[0124] Polyethylene terephthalate, also known as PET, is a plastic material made by polymerizing ethylene and terephthalic acid. It is highly valued as an environmentally friendly material due to its high durability, chemical stability, and recyclability.

[0125] On the other hand, as one embodiment of the present invention, an oxygen generating member (400) formed by injecting an oxygen generating compound (410) into a film-shaped pouch (420) made of the material described above can be inserted between the upper housing (340) and the intermediate housing (330) of the exhaust section.

[0126] On the other hand, the oxygen generating component (400) of the present invention was tested using the EPA 9045D, EPA 6020, EPA 8081A, and EPA 8260B GCMS test methods, which are test methods for analyzing environmental pollutants established by the U.S. Environmental Protection Agency (EPA). As a result, the pH was greater than 12, and no volatile organic compounds or insecticides were detected, confirming its chemical stability. It was also confirmed to be useful for coronavirus removal, sterilization, antibacterial action, deodorization, fragrance application, and oxygen supply, and has obtained FDA NDC registration certification.

[0127] The following describes, with reference to Figures 7 and 8, the operation process of the exhaust section in the transport path of water vapor and carbon dioxide generated by the breathing of a wearer wearing the dust mask of the present invention, as well as the process by which oxygen is generated in the oxygen generating member and supplied to the wearer.

[0128] First, as shown in Figure 7(a), the dust mask of the present invention is configured such that a lower housing (310), a valve (320), an intermediate housing (330), and an upper housing (340) are coupled to the outer surface of the mask body (100) in that order, and an exhaust section is formed between the intermediate housing (330) and the upper housing (340) in which an oxygen generating member (400) is inserted.

[0129] When a wearer wearing such a dust mask of the present invention exhales, as shown in Figure 7(b), the wearer's exhaled breath, which contains water vapor (H2O) and carbon dioxide (CO2), moves the valve (320) that is blocking the first exhaust port (311) formed through the mask body (100) and the lower housing (310), causing the first exhaust port (311) to open. The exhaled breath is discharged through the opened first exhaust port (311) and can be discharged to the outside through a third exhaust port (not shown) formed in the intermediate housing of the exhaust section and a second exhaust port (not shown) formed in the upper housing, although these are not shown in Figure 7.

[0130] To explain in more detail, as shown in Figure 7(b), when exhaled air is generated from the mouth and nose of a wearer wearing the mask body (100), the lower end of the valve (320), which is freely movable with respect to a fixed area, moves away from the aforementioned first exhaust port (311), thereby opening the first exhaust port (311). It is preferable to understand that the exhaled air is discharged through the opened first exhaust port (311) and then discharged to the outside through the third and second exhaust ports of the exhaust section.

[0131] At this time, the wearer's exhaled breath is discharged from the first exhaust port (311), and at the same time, a portion of the exhaled breath generated by the wearer is supplied to the oxygen generating member (400) inserted between the upper housing (340) and the intermediate housing (330) of the exhaust section via the first through-hole (315) formed through the mask body (100) and the lower housing (310), and the second through-hole (331) formed through the intermediate housing (330).

[0132] Furthermore, when a portion of the wearer's exhaled breath is supplied to the oxygen generating component (400), the water vapor and carbon dioxide contained in the exhaled breath pass through the pouch (420) of the oxygen generating component (400), which is made of a porous material, and are transferred to the oxygen generating compound (410) inside the oxygen generating component (400). As a result, the water vapor and carbon dioxide undergo a chemical reaction with the oxygen generating compound (410), generating oxygen.

[0133] On the other hand, as shown in Figure 8, when the wearer wearing the mask body (100) inhales, the oxygen generated in the oxygen generating member (400) moves into the inside of the mask body (100) through the second through-hole (331) of the intermediate housing (330) and the first through-hole (315) formed through the mask body (100) and the lower housing (310). This can be understood as supplying oxygen to the wearer and allowing the wearer to inhale oxygen into their body.

[0134] Furthermore, the exhaled air generated from the wearer's breathing contains water vapor and carbon dioxide, making it denser and warmer. Therefore, as shown in Figure 7(b), when the wearer exhales, the valve (320) moves and the first exhaust port (311) opens. When exhaled air is expelled through the opened first exhaust port (311), the air density and temperature inside the mask body (100) decrease, and a low pressure can be formed.

[0135] Therefore, due to the low pressure formed inside the mask body (100), oxygen generated in the oxygen generating member (400) can move into the inside of the mask body (100) through the second through hole (331) and the first through hole (315) and be supplied to the wearer.

[0136] Furthermore, while the wearer is receiving oxygen from the oxygen generating member (400) via their inhalation or the low pressure formed inside the mask body, the unfixed lower end of the valve (320) moves again toward the first exhaust port (311) as the wearer inhales, thereby blocking the intake of outside air.

[0137] As a result, when the wearer inhales, the first exhaust port (311) of the exhaust section is blocked, preventing harmful external air from being supplied to the wearer through the exhaust section, while simultaneously allowing oxygen to be supplied from the oxygen generating member (400). Consequently, it is possible to safely protect the wearer's respiratory system from harmful substances generated in industrial settings and to facilitate the wearer's breathing.

[0138] Furthermore, the compartment separation portion (314) formed in the lower housing (310) is in close contact with the inside of the intermediate housing (330), thereby dividing the area between the lower housing (310) and the intermediate housing (330) vertically. This prevents the oxygen generated from the oxygen generating member (400) from leaking to the outside through the second and third exhaust ports formed in the exhaust section. The oxygen generated in the oxygen generating member (400) is then supplied directly to the wearer through the first and second through holes formed at the upper end of the exhaust section, thereby improving oxygen supply efficiency.

[0139] In other words, the dust mask of the present invention can control the opening and closing of the exhaust port through the wearer's breathing, including exhalation and inhalation, and divides the area within the exhaust port vertically through a compartmentalization section. As a result, the space formed at the upper end functions as a passage through which the wearer's exhaled breath is supplied to the oxygen generating member and the generated oxygen moves, while the space formed at the lower end of the exhaust port functions as a passage through which the wearer's exhaled breath is discharged to the outside. These features improve the user's breathing environment and prevent air contamination inside the mask body, and enable the wearer to maintain breathing for a long period of time without receiving oxygen from an external source.

[0140] In the following, with reference to Figures 9 to 13, an industrial dust mask equipped with an oxygen generating member according to another embodiment of the present invention will be described.

[0141] In another embodiment of the present invention, as shown in Figures 9 and 10, the exhaust section may comprise a first housing (500) and a second housing (600).

[0142] In this case, the first housing (500) performs the same function as the lower housing (310) described above and is formed in a location within the area of ​​the mask body (100) that corresponds to either the mouth or nose of the wearer. A fourth exhaust port (510) is formed in one area of ​​the lower end of the first housing (500), which penetrates the mask body (100) to expel the wearer's exhaled breath, and may include a valve membrane (520) capable of blocking the fourth exhaust port (510).

[0143] Here, the fourth exhaust port (510) can be understood as performing the same function as the first exhaust port described above. Specifically, the fourth exhaust port (510) is formed in the area of ​​the mask body (100) at a position corresponding to either the wearer's mouth or nose, and is of a set size. For example, it can be made up to be about 1 mm in size, and multiple ports can be formed as shown in Figure 9 to ensure a ventilation effect.

[0144] The size and number of the fourth exhaust port (510) in other embodiments of the present invention can be changed and modified as needed, and the present invention is not limited thereto.

[0145] On the other hand, the valve (520) controls the opening and closing of the fourth exhaust port (510) via the wearer's breathing. As shown in Figure 9, it is formed larger than the area in which the fourth exhaust port (510) is formed, and is installed so as to block the fourth exhaust port (510) by fixing one area of ​​its upper or lower end to the outer surface of the mask body (100). The area excluding the fixed area is movable in accordance with the wearer's breathing, and this can be understood as controlling the opening and closing of the fourth exhaust port (510).

[0146] Specifically, referring to Figure 12, when exhalation occurs from the wearer's mouth and nose, the valve (520) allows a portion of the valve (520) that is freely movable relative to a fixed area to move away from the fourth exhaust port (510), thereby allowing the exhaled air to be discharged through the fourth exhaust port (510). Furthermore, when inhalation occurs from the wearer's mouth and nose, the valve (520) can block the fourth exhaust port (510), thereby blocking the intake of outside air.

[0147] In other words, as shown in Figure 12(b), as the wearer exhales, the unfixed portion of the valve (520) moves outward from the mask body (100), causing the valve (520) to separate from the fourth exhaust port (510), and the wearer's exhaled air is expelled from the fourth exhaust port (510). Then, as the wearer inhales, as shown in Figure 12(a), the unfixed portion of the valve (520) moves again towards the fourth exhaust port (510), blocking the fourth exhaust port (510), thereby blocking the intake of outside air.

[0148] In other words, exhalation is the air expelled from the wearer and moving to the outside, and inhalation is the process by which the wearer inhales outside air. Therefore, when the valve (520) is opened by the wearer's exhalation, water vapor and carbon dioxide contained in the wearer's exhalation are expelled through the fourth exhaust port (510). On the other hand, when the valve (520) closes the fourth exhaust port (510) by the wearer's inhalation, it is possible to prevent harmful substances from the outside from being inhaled through the fourth exhaust port (510).

[0149] On the other hand, in another embodiment of the present invention, it is preferable that the valve membrane (520) is formed in accordance with the number of fourth exhaust ports (510), as shown in Figure 9, but it is also possible to configure multiple fourth exhaust ports (510) to be opened and closed by a single valve membrane (520). In this case, it is preferable that the size of the valve membrane (520) be formed to be large enough to block all of the multiple fourth exhaust ports (510), and the present invention is not limited thereto.

[0150] On the other hand, the valve membrane (520) can be understood to perform the same function as the valve membrane (320) according to one embodiment of the present invention shown in Figure 8.

[0151] Returning to Figure 9 and continuing the explanation, the first housing (500) may have a first connecting portion (530) to which the second housing, which will be described later, is connected.

[0152] Specifically, the first coupling portion (530) is formed along the outer circumferential surface of the region where the fourth exhaust port (510) and the valve membrane (520) are formed. In this case, the first coupling portion (530) is formed to be larger than the size of the valve membrane (520), and a region of the second housing, which will be described later, can be coupled to it.

[0153] Here, it is preferable that the first joint (530) and a region of the second housing, which will be described later, are joined using a fitting method. However, any joining method other than the fitting method is possible as long as it is a method that allows the second housing, which will be described later, to be joined to the first housing (500), and the present invention is not limited thereto.

[0154] Furthermore, after the first coupling portion (530) of the first housing (500) and the second housing, which will be described later, are coupled, the wearer's exhaled breath moves from the inside to the outside of the mask body (100) and is supplied to the second housing through the fourth exhaust port (510), which is opened by the movement of the valve (520) in response to the wearer's exhalation. This can be understood as generating oxygen in the second housing.

[0155] On the other hand, in another embodiment of the present invention, as shown in Figures 10 to 13, the second housing (600) is coupled to the first housing (500). A housing space (610) is formed in one region inside the second housing (600) to house an oxygen generating member (400) that generates oxygen through a chemical reaction with water vapor and carbon dioxide generated from the wearer's respiration. Specifically, the housing space (610) is formed in one region of the upper end, and a fifth exhaust port (620) is formed in one region of the lower end to discharge the wearer's exhaled breath discharged from the fourth exhaust port (510) of the first housing (500) to the outside. A through hole (621) may be formed that penetrates the lower end of the housing space (610) and the upper end of the fifth exhaust port (620).

[0156] In this case, the second housing (600) may be understood to have a form similar to the configuration in which the upper housing and the intermediate housing are combined according to the above-described embodiment of the present invention. Furthermore, the fifth exhaust port (620) may be understood to perform the function of expelling the wearer's exhaled breath to the outside, similar to the second and third exhaust ports according to the above-described embodiment of the present invention.

[0157] On the other hand, the fifth exhaust port (620) is formed by penetrating from one side to the other of the second housing (600) adjacent to the first housing (500). As shown in Figures 10 and 11, by forming multiple fifth exhaust ports (620), the device can be configured to effectively expel the wearer's exhaled breath to the outside.

[0158] Furthermore, as shown in Figures 11 and 12, the through-hole (621) is formed to penetrate between the fifth exhaust port (620) and the housing space (610) so that, in the process of the wearer's exhaled breath being discharged to the outside through the fifth exhaust port (620) of the second housing (600) via the fourth exhaust port (510), the wearer's exhaled breath is supplied to the housing space (610) of the oxygen generating member (400) formed at the upper end of the fifth exhaust port (620). In this way, the through-hole (621) can function as a pathway for the movement of a portion of the wearer's exhaled breath.

[0159] Therefore, it is preferable to understand that the wearer's exhaled breath moves through the through-hole (621) to the oxygen generating member (400) housed in the containment space (610), and that the water vapor and carbon dioxide contained in the wearer's exhaled breath undergo a chemical reaction with the oxygen generating compound (410) in the oxygen generating member (400) to generate oxygen. The generated oxygen then moves again through the through-hole (621) and is supplied to the wearer's respiratory side through the fourth exhaust port (510).

[0160] On the other hand, in another embodiment of the present invention, the second housing (600) may include an oxygen generating member insertion portion (630) and a second coupling portion (640), as shown in Figures 11 to 13.

[0161] As shown in Figure 11, the oxygen generating member insertion portion (630) is formed in one area of ​​the second housing (600) and may be formed at a position corresponding to the housing space (610) so that the oxygen generating member (400) can be inserted into the housing space (610) inside the second housing (600) from the outside.

[0162] Furthermore, it is preferable that the oxygen generating member insertion portion (630) is formed in a circular shape so that the film-shaped oxygen generating member (400) can be inserted after being wound into a roll. It is preferable that when the rolled oxygen generating member (400) is inserted into the containment space (610) in the second housing (600), it expands from a roll shape to a film shape due to the shape-restoring force of the oxygen generating member (400) and is fixed within the containment space (610).

[0163] On the other hand, the oxygen generating member (400) according to another embodiment of the present invention may be understood to have the same configuration as the oxygen generating member according to the above-described embodiment and to perform the same function.

[0164] Specifically, the oxygen generating member comprises an oxygen generating compound (410) and a pouch (420), and the pouch may be made of at least one of the following materials: Tyvek, elastic nonwoven fabric, polyamide, and polyethylene terephthalate.

[0165] In this case, the material used in the pouch can be understood to have shape-restoring properties, meaning that even if its shape is deformed, it can be restored to its original shape.

[0166] As a result, as shown in Figure 11, when the rolled oxygen generating member (400) is inserted into the oxygen generating member insertion section (630) formed in the second housing (600), as shown in Figure 12, the oxygen generating member (400) expands in the containment space (610) within the second housing (600) due to the shape-restoring force of the pouch (420) of the oxygen generating member (400), and can be fixed in the containment space (610) within the second housing (600).

[0167] Therefore, in another embodiment of the present invention, an oxygen generating member (400) in the form of a film having shape-recovering properties is wound into a roll and inserted into a second housing (600). The inserted oxygen generating member (400) is fixed inside the second housing (600) by restoring to its film shape, preventing the oxygen generating member (400) from detaching to the outside.

[0168] On the other hand, although not shown in the attached drawings, another embodiment of the present invention may further include a fixing cap (not shown) that can seal the oxygen generating member insertion portion formed by penetrating the housing space in which the oxygen generating member is housed from a region on the outer surface of the second housing, thereby sealing the housing space in which the oxygen generating member is housed. Specifically, after inserting the oxygen generating member wound in a roll into the oxygen generating member insertion portion, a fixing cap formed in a shape corresponding to the shape of the oxygen generating member insertion portion is attached to the oxygen generating member insertion portion to seal the housing space in which the oxygen generating member is housed. This prevents the oxygen generating member from detaching from the housing space in the second housing and prevents the oxygen generated from the oxygen generating member from leaking to the outside.

[0169] Returning to Figure 12 and continuing the explanation, the second coupling portion (640) is formed on one surface of the second housing (600) adjacent to the mask body (100) so that the second housing (600) can be coupled to the first housing (500) formed on the mask body (100). It is preferable to understand that the second coupling portion (640) is formed in a manner that allows it to be coupled to and fixed to the first coupling portion (530) of the first housing (500) as shown in Figures 9 and 12.

[0170] In this case, it is preferable that the second connecting portion (640) is fitted and connected to the first connecting portion (530), as shown in Figure 12. However, any connecting method other than the fitting method is possible as long as the second housing (600) is stably connected to the first housing (500) formed on the mask body (100) and the second housing (600) can be fixed, and the present invention is not limited thereto.

[0171] The following describes, with reference to Figures 12 and 13, the operation process of the valve membrane associated with the transport path of water vapor and carbon dioxide generated by the respiration of a wearer wearing an industrial dust mask equipped with an oxygen generating member according to another embodiment of the present invention, as well as the process by which oxygen is generated in the oxygen generating member inserted in the second housing and supplied to the wearer.

[0172] First, in a second housing according to another embodiment of the present invention, the wearer's exhaled breath discharged from the fourth exhaust port is discharged to the outside through the fifth exhaust port, and at the same time, the wearer's exhaled breath is supplied to a housing space in which an oxygen generating member is housed to generate oxygen. When the wearer's exhaled breath is discharged to the outside through the fourth and fifth exhaust ports, the low pressure formed in the region between the fourth and fifth exhaust ports allows the oxygen generated in the oxygen generating member inserted into the second housing to be supplied to the wearer through the fourth exhaust port.

[0173] To explain in more detail, the exhaled air generated from the wearer's breathing contains water vapor and carbon dioxide, so it is dense and hot. Therefore, as shown in Figure 12(b), when the wearer exhales, the valve (520) moves and the fourth exhaust port (510) opens. When the exhaled air is expelled through the opened fourth exhaust port (510), the air density and temperature inside the mask body (100) and in the region between the fourth exhaust port (510) and the fifth exhaust port (620) decrease, and a low pressure can be formed.

[0174] To explain in more detail, as shown in Figure 12(b), when exhaled air is generated from the wearer's mouth and nose, a portion of the valve (520) that is freely movable relative to a fixed area moves away from the fourth exhaust port (510), thereby opening the fourth exhaust port (510). The exhaled air discharged through the opened fourth exhaust port (510) is discharged to the outside through the fifth exhaust port (620) and at the same time supplied to the oxygen generating member (400) housed in the containment space (610) through the through hole (621) formed in the second housing (600). In this process, it is preferable to understand that the air density inside the mask body (100) and in the area between the fourth exhaust port (510) and the fifth exhaust port (620) decreases, the temperature drops, and a low pressure is formed.

[0175] Furthermore, the wearer's exhaled breath is discharged through the fourth exhaust port (510) and simultaneously supplied to the oxygen generating element (400) inside the second housing (600). As a result, the water vapor and carbon dioxide contained in the wearer's exhaled breath are transferred to the oxygen generating element (400), and the oxygen generating compound (410) inside the oxygen generating element (400) generates oxygen through a chemical reaction with the water vapor and carbon dioxide.

[0176] On the other hand, as shown in Figure 13, the oxygen generated in the oxygen generating member (400) moves at the moment the fourth exhaust port (510) is open due to the low pressure created in the region between the fourth exhaust port (510) and the fifth exhaust port (620), and the low pressure formed inside the mask body (100). Specifically, the oxygen moves from the housing space (610) in which the oxygen generating member (400) is housed, through the through hole (621) and the fifth exhaust port (620), and then through the fourth exhaust port (510) into the inside of the mask body (100). This can be understood as supplying oxygen to the wearer.

[0177] Furthermore, when oxygen is supplied to the wearer, the wearer inhales oxygen into their body through inhalation, and simultaneously, as shown in Figure 12(a), the unfixed portion of the valve (520) moves again toward the fourth exhaust port (510) and blocks the fourth exhaust port (510). This can be understood as blocking the intake of outside air.

[0178] In other words, an industrial dust mask equipped with an oxygen generating member according to another embodiment of the present invention transmits the wearer's exhaled breath to the oxygen generating member through a fourth exhaust port of a first housing formed in the mask body, and a fifth exhaust port and through-hole of a second housing coupled to the first housing, thereby generating oxygen. The oxygen generated from the oxygen generating member is then supplied to the wearer through the low pressure inside the mask body formed by the wearer's exhaled breath, and the low pressure in the region between the fourth and fifth exhaust ports. The wearer inhales the supplied oxygen into their body through inhalation, and it is preferable that, in conjunction with the wearer's inhalation, a valve closes the fourth exhaust port, thereby preventing harmful outside air from being supplied to the wearer through the fourth and fifth exhaust ports.

[0179] In summary, according to the embodiment of the present invention described above, the industrial dust mask including the oxygen generating member according to the present invention has the effect of safely protecting the wearer's respiratory system from harmful substances generated in industrial sites and simultaneously assisting the wearer's breathing by inserting the oxygen generating member into the exhaust port of the dust mask, thereby expelling the wearer's exhaled breath to the outside through the exhaust port, while simultaneously transmitting a portion of the exhaled breath to the oxygen generating member to generate oxygen, and then transmitting the oxygen generated from the oxygen generating member again while the wearer inhales.

[0180] Furthermore, according to one embodiment of the present invention, by including silica gel and carrageenan, which have excellent moisture absorption properties, in addition to the oxidizing agent and stabilizer, in the oxygen generating compound that constitutes the oxygen generating member, moisture generated during the oxygen generation process of the oxygen generating compound is absorbed, thereby preventing low-temperature burns caused by moisture generated during the oxygen generation process of the oxygen generating compound.

[0181] Furthermore, according to one embodiment of the present invention, the oxygen generating component has effects that are useful for coronavirus removal, sterilization, antibacterial action, deodorization, fragrance, and oxygen supply.

[0182] Accordingly, by applying an oxygen generating member according to one embodiment of the present invention to a dust mask, it is possible to provide effects such as blocking harmful substances generated in industrial sites, as well as coronavirus removal, sterilization, antibacterial properties, and deodorization, and to supply fragrance and oxygen to the wearer of the dust mask.

[0183] Furthermore, according to one embodiment of the present invention, by providing the oxygen generating member in the form of a film, the size of the exhaust section into which the oxygen generating member is inserted can be effectively reduced, which has the effect of providing convenience to the wearer when using a dust mask.

[0184] Furthermore, according to one embodiment of the present invention, by dividing the area within the exhaust section vertically through a compartmental separation section, a portion of the wearer's exhaled breath is transmitted to the oxygen generating member through first and second through holes formed at the upper end of the exhaust section, and the remaining exhaled breath is discharged to the outside through first to third exhaust ports formed at the lower end of the exhaust section. This allows for adjustment of the amount of the wearer's exhaled breath transmitted to the oxygen generating member, thereby improving the oxygen generation efficiency of the oxygen generating member, improving the wearer's breathing environment, and preventing air contamination inside the mask body.

[0185] Furthermore, according to one embodiment of the present invention, by dividing the area within the exhaust section into upper and lower sections, the oxygen generated by the oxygen generating member is directly transmitted to the wearer through the first and second through holes formed at the upper end of the exhaust section, thereby preventing oxygen from leaking to the outside and effectively supplying oxygen to the wearer.
