Industrial dust mask comprising an oxygen generating element

Abstract

The present invention relates to an industrial dust mask including an oxygen generating element, and more particularly, to an industrial dust mask including a mask body, a fixing band for fixing the mask body to a face of a wearer, an exhaust unit formed in an outer surface area of the mask body and provided with an exhaust port for discharging exhaled air of the wearer to the outside, and an oxygen generating element inserted into an area of the exhaust unit, which receives water vapor and carbon dioxide generated by breathing of the wearer and generates oxygen by a chemical reaction. A through hole is formed in the mask body and the exhaust unit so that a part of the exhaled air of the wearer discharged to the outside through the exhaust port of the exhaust unit is transferred to the oxygen generating element inserted in the exhaust unit through the through hole to generate oxygen. The oxygen generated by the oxygen generating element is supplied to the wearer through the through hole when the mouth and nose of the wearer inhale.

Description

[Technical Field] This invention relates to a dust mask capable of blocking harmful substances generated in industrial environments. Specifically, the invention relates to an industrial dust mask comprising an oxygen-generating element inserted into the mask's exhaust unit. The mask is configured to expel the wearer's exhaled air to the outside through the exhaust unit, while simultaneously transferring a portion of the exhaled air to the oxygen-generating element to produce oxygen. When the wearer inhales, the generated oxygen is returned to the wearer, thereby protecting the wearer's respiratory system from harmful substances in industrial environments while promoting smooth breathing by supplying oxygen. [Background Technology] Dust masks are typically protective gear worn on the face by workers in dust-generating industrial environments. They protect workers' health by preventing dust generated during work from entering the body through the mouth and nose.

[0003] This traditional dust mask includes: a mask body shaped to cover the mouth and nose; air intake ports installed on both sides of the mask body with filters embedded therein; an exhaust port installed in the lower middle part of the mask body; and a fixing strap connected to the mask body by straps to secure the mask body to the head and fix it to the face.

[0004] When workers wear the aforementioned dust masks, the masks cover the mouth and nose and allow breathing through the inhalation and exhalation ports, thereby preventing harmful substances generated during the work from entering the human body.

[0005] However, in traditional dust masks, when the wearer exhales, the pressure between the mask body and the wearer's face increases rapidly. This causes the mask body to detach from the face to allow air to escape. At this time, the exhaled air escaping through the upper part of the mask body (i.e., the nose area) can cause the goggles of the wearer to fog up. This fogging can obstruct vision and increase the risk of accidents.

[0006] As an effort to solve this problem, Korean Patent No. 10-1692949 discloses a dust mask technology that aims to prevent glasses from fogging up by guiding exhaled air, which should be discharged upwards, through an independent space inside the mask to the bottom of the mask for rapid discharge.

[0007] However, while the aforementioned prior art has the advantage of preventing fogging by guiding the wearer's exhalation and directing it to the bottom of the mask, it may cause breathing problems when worn for extended periods because the mask fits tightly against the wearer's face and oxygen supply is not smooth. [Summary of the Invention] [Purpose of the Invention] The present invention aims to solve the problems in the prior art described above. The object of the present invention is to provide an industrial dust mask comprising an oxygen-generating element, which is inserted into the exhaust unit of the dust mask. The mask is configured to expel the wearer's exhaled air to the outside through the exhaust unit, while simultaneously transferring a portion of the exhaled air to the oxygen-generating element to produce oxygen. When the wearer inhales, the generated oxygen is returned to the wearer, thereby protecting the wearer's respiratory system from harmful substances in industrial environments while promoting smooth breathing by supplying oxygen.

[0009] [Technical Solution] To achieve the above objectives, an industrial dust mask including an oxygen-generating element according to an embodiment of the present invention includes: a mask body; a fixing strap configured to secure the mask body to a wearer's face; an exhaust unit formed in a region on the outer surface of the mask body, the exhaust unit having an exhaust port to expel the wearer's exhaled air to the outside; and an oxygen-generating element inserted into a region within the exhaust unit, the oxygen-generating element being configured to generate oxygen by inducing a chemical reaction upon receiving respiratory water vapor and carbon dioxide generated by the wearer's breathing. A through-hole is formed in a region penetrating the mask body and the exhaust unit, such that a portion of the wearer's exhaled air, expelled to the outside through the exhaust port of the exhaust unit, is transmitted via the through-hole to the oxygen-generating element inserted in the exhaust unit to generate oxygen. When the wearer inhales through their mouth and nose, the oxygen generated from the oxygen-generating element is supplied to the wearer via the through-hole.

[0010] In one or more embodiments, the exhaust unit may include: a lower housing formed in the mask body region at a location corresponding to either the wearer's mouth or nose, the lower housing including a first exhaust port formed in its lower end region and penetrating the mask body, and a first through hole formed in its upper end region and penetrating the mask body; a valve formed larger than the first exhaust port and having a hole formed in its upper end region, the valve being mounted by inserting and securing it to a fixing portion protruding from the region of the lower housing to cover the first exhaust port, wherein the region of the valve other than the fixing region may be configured according to... The device moves in response to the wearer's breathing; an upper housing coupled to the lower housing, the upper housing including second exhaust ports formed on its two side regions and lower end region for discharging the wearer's exhaled air to the outside; and an intermediate housing inserted into the inner side of the upper housing after the oxygen-generating element is inserted into the upper housing to secure the oxygen-generating element, the intermediate housing including: a second through hole formed at a position corresponding to the first through hole; a third exhaust port shaped corresponding to the second exhaust port and formed on its two side regions and lower end region; and a valve fixing portion protruding from its lower surface region to secure the upper end of the valve. When the intermediate housing is coupled to the upper housing, the second exhaust port and the third exhaust port are preferably arranged in a straight line.

[0011] In one or more embodiments, the lower housing may include a partition portion protruding from the upper surface region of the lower housing and formed in the region between the first through hole and the fixing portion. When the upper housing, to which the intermediate housing is inserted, is coupled to the lower housing, the protruding end of the partition portion preferably comes into close contact with the lower end of the second through hole formed in the intermediate housing to vertically separate the space between the lower housing and the intermediate housing.

[0012] In one or more embodiments, the first through-hole and the second through-hole may be arranged in a straight line such that when the wearer exhales through their mouth and nose, a portion of the exhaled air is transmitted from the interior of the mask body to the oxygen-generating element via the first and second through-holes. When the wearer inhales through their mouth and nose, oxygen generated from the oxygen-generating element is preferably supplied to the wearer inside the mask body via the second through-hole and the first through-hole.

[0013] In one or more embodiments, the lower housing may include a protrusion and a coupling groove formed along its outer peripheral surface, and the upper housing may include a coupling protrusion protruding from its lower end for insertion into the coupling groove. When the coupling protrusion of the upper housing is inserted into the coupling groove of the lower housing, the lower end of the intermediate housing inserted in the upper housing preferably contacts the upper surface of the protrusion, and the lower end of the upper housing is fitted onto the protrusion, thereby sequentially coupling the lower housing, the valve, the intermediate housing, the oxygen-generating element, and the upper housing to form the exhaust unit containing the oxygen-generating element.

[0014] In one or more embodiments, the valve may be configured such that when the wearer exhales through their mouth and nose, a freely movable portion of the valve relative to a fixed area separates from the first exhaust port to allow exhaled air to escape through the first exhaust port. When the wearer inhales through their mouth and nose, the valve blocks the first exhaust port to prevent the inhalation of outside air. The exhaled air exiting through the first exhaust port is preferably discharged to the outside via the second and third exhaust ports.

[0015] In one or more embodiments, the oxygen-generating element may include: an oxygen-generating compound configured to generate oxygen by reacting with a reactant comprising at least one of water vapor and carbon dioxide; and a bag formed into a thin film shape having a predetermined size for containing the oxygen-generating compound therein.

[0016] In one or more embodiments, the oxygen-generating compound may be formed by mixing the following components: an oxidant comprising at least one of potassium superoxide and sodium peroxide; a stabilizer comprising at least one or a combination of two or more of calcium hydroxide, aluminum hydroxide and magnesium hydroxide; and silica gel and carrageenan in a predetermined ratio.

[0017] In one or more embodiments, the bag body may be formed of at least one material selected from the group consisting of Tyvek, elastic nonwoven fabric, polyamide, and polyethylene terephthalate.

[0018] [Beneficial Effects] The industrial dust mask containing an oxygen-generating element according to the present invention, by inserting an oxygen-generating element into the exhaust unit, allows part of the wearer's exhalation to be transferred to the oxygen-generating element to generate oxygen, and during inhalation, the generated oxygen is retransmitted to the wearer, thereby protecting the wearer's respiratory system from harmful substances in industrial environments while promoting smooth breathing by supplying oxygen.

[0019] Furthermore, according to one or more embodiments, by adding silica gel and carrageenan, which have excellent hygroscopic properties, to the oxygen-generating compound in addition to oxidants and stabilizers, it is possible to prevent low-temperature burns caused by moisture during the oxygen-generating process of the oxygen-generating compound.

[0020] Furthermore, according to one or more embodiments, the oxygen-generating element has beneficial effects such as removing coronaviruses, sterilizing, antibacterial, deodorizing, providing fragrance, and supplying oxygen.

[0021] Therefore, by applying the oxygen-generating element according to embodiments of the present invention to a dust mask, it is possible to block harmful substances in the industrial environment while producing effects such as removing coronaviruses, sterilization, antibacterial, and deodorization, and providing fragrance and oxygen to the wearer.

[0022] Furthermore, according to one or more embodiments, by providing the oxygen-generating element in the shape of a thin film, the size of the exhaust unit inserted into the element can be effectively reduced, thereby improving the convenience for the wearer.

[0023] Furthermore, according to one or more embodiments, the space within the exhaust unit is vertically divided by a partition, such that part of the wearer's exhalation is transmitted to the oxygen-generating element through a first and second through-hole formed in the upper part of the exhaust unit, while the remaining exhalation is discharged to the outside through the first to third exhaust ports formed in the lower part of the exhaust unit. This configuration allows for regulation of the amount of exhalation transmitted to the oxygen-generating element, thereby improving oxygen production efficiency, improving the wearer's breathing environment, and preventing air pollution inside the mask body.

[0024] Furthermore, according to one or more embodiments, by vertically dividing the space within the exhaust unit, oxygen generated by the oxygen-generating element is directly delivered to the wearer via a first through-hole and a second through-hole at the top of the exhaust unit. This prevents oxygen leakage to the outside and ensures an effective oxygen supply to the wearer.

[0038] This invention relates to an industrial dust mask incorporating an oxygen-generating element. Specifically, the purpose of this invention is to provide an industrial dust mask incorporating an oxygen-generating element. By inserting the oxygen-generating element into the exhaust unit of the dust mask, the wearer's exhaled air is discharged to the outside through the exhaust unit, while a portion of the exhaled air is transferred to the oxygen-generating element to generate oxygen. During inhalation, the oxygen generated by the oxygen-generating element is transferred back to the wearer, thereby protecting the wearer's respiratory system from harmful substances generated in industrial environments, while simultaneously promoting smooth breathing by supplying oxygen.

[0039] To provide a more detailed description, the present invention will now be described in conjunction with the accompanying drawings, and multiple drawings may be referenced simultaneously to describe a technical feature and constituent component of the present invention.

[0040] A brief review of the illustrations accompanying the description of this invention, Figure 1 A schematic shape example of an industrial dust mask including an oxygen-generating element according to an embodiment of the present invention is shown. Figure 2 An exploded view of an exhaust unit according to an embodiment of the present invention is shown.

Furthermore, Figure 6 A schematic shape example of the upper housing according to an embodiment of the present invention is shown. Figure 7 and Figure 8 A side sectional view of an industrial dust mask including an oxygen-generating element according to an embodiment of the present invention is shown. Figures 9 to 13 An example of an industrial dust mask comprising an oxygen-generating element according to other embodiments of the present invention is shown.

[0041] Furthermore, in the following description, certain components may be omitted in the accompanying drawings, or excessively enlarged or reduced to explain the function of each component of the invention. However, it should be understood that such illustrations do not limit the technical features and scope of the invention.

[0042] refer to Figure 1 and Figure 2 ,in Figure 1 A schematic shape of an industrial dust mask including an oxygen-generating element according to an embodiment of the present invention is shown. Figure 2 An exploded view of the exhaust unit is shown. The industrial dust mask including an oxygen-generating element according to the present invention mainly comprises a mask body 100, a fixing strap 200, an exhaust unit 300, and an oxygen-generating element 400.

[0043] First, the mask body 100 constitutes the overall appearance of an industrial dust mask containing oxygen-generating elements (hereinafter referred to as "the dust mask of the present invention"), and can be formed to simultaneously cover the wearer's mouth and nose.

[0044] In this case, the mask body 100 can be configured with various materials and structures according to the standards for industrial dust masks, which are classified into extra-grade, first-grade, and second-grade based on filtration efficiency, leakage rate, etc. In the following description, the mask body 100 can be configured to include masks of all known types and materials, and the invention is not limited thereto.

[0045] Furthermore, in this invention, it is preferred to understand it as forming an exhaust valve type dust mask in a filter respirator, to distinguish it from a replaceable filter respirator.

[0046] Meanwhile, a nose clip 110, shaped to correspond to the bridge of the wearer's nose, can be formed at the upper end of the mask body 100. The nose clip 110 is preferably made of a metal wire that can be deformed.

[0047] Understandably, the purpose is to ensure that the mask body 100 is in close contact with the wearer's nose bridge by bending the nose clip 110 into a shape corresponding to the wearer's nose bridge.

[0048] Meanwhile, although not shown in the accompanying drawings, as another embodiment of the invention, a silicone portion (not shown) may be formed along the outer periphery of the inner surface of the mask body adjacent to the wearer's face.

[0049] In this configuration, the silicone portion serves to fit snugly against the wearer's skin when the mask body is worn, thereby reliably blocking external air. Furthermore, since the silicone portion is formed using a flexible silicone material, it conforms closely to the wearer's facial contours without any gaps when the mask body is worn. Therefore, it can be understood that it can fundamentally block external air or external pollutants introduced between the mask body and the wearer's face.

[0050] Back Figure 1 The mask body 100 may have fixing straps 200 formed on the left and right sides. The fixing straps 200 are components used to fix the mask body to the wearer's face, and are preferably formed in a shape that surrounds the wearer's head so that it is not easy to fall off the face.

[0051] In this case, the fixing strap 200 can be made of elastic fiber material, thereby producing an effect that can be flexibly adjusted according to the wearer's head size and provide a soft and comfortable fit.

[0052] Furthermore, although the fixing strap 200 can be made of elastic rubber, it can also be made of any elastic material that is easy to adjust in length; the present invention is not limited thereto.

[0053] Furthermore, although not shown in the accompanying drawings, as another embodiment of the invention, the fixing strap 200 may further include a length adjustment unit (not shown) to have a structure with an adjustable fixing strap length. In this case, the length adjustment unit serves to finely adjust the fixing strap length according to the wearer's head circumference, thereby producing the effect of making the dust mask of the present invention more stably fixed on the wearer's face.

[0054] Furthermore, as an embodiment of the present invention, although the fixing strap 200 in the drawings is shown in the form of wrapping around the wearer's head, an ear loop fixing strap may also be used, and the present invention is not limited thereto.

[0055] As another embodiment of the present invention, when using ear-loop fastening straps, the length can be adjusted and the fit improved by additional structures such as hooks. Specifically, by placing the hooks at the back of the wearer's head and coupling the hooks with the fastening straps formed at both ends of the mask body to wrap around the wearer's head, the fit can be improved. This can also reduce the burden on the wearer's ears when wearing the dust mask of the present invention for extended periods.

[0056] Meanwhile, an exhaust unit 300 may be formed on the main body 100 of the mask.

[0057] like Figures 1 to 6 As shown, the exhaust unit 300 is formed in the area of ​​the outer surface of the mask body 100 and may include an exhaust port to allow the wearer's exhaled air to be discharged to the outside.

[0058] The exhaust unit 300 may include a lower housing 310, a valve 320, an intermediate housing 330, and an upper housing 340.

[0059] The exhaust unit 300 may have multiple exhaust ports for venting the wearer's exhaled air. For example, the exhaust ports may include a first exhaust port 311 formed in the lower housing 310, a third exhaust port 332 formed in the intermediate housing 330, and a second exhaust port 341 formed in the upper housing 340, which together constitute the exhaust unit 300.

[0060] Regarding the lower housing 310, the lower housing 310 is formed in the region of the mask body 100 corresponding to any position in the wearer's mouth and nose. The lower housing 310 may include a first exhaust port 311 formed in its lower region and penetrating the mask body 100, and a first through hole 315 formed in its upper region and penetrating the mask body 100.

[0061] In this case, the first exhaust port 311 is preferably formed near the wearer's mouth to effectively expel exhaled air. Specifically, as Figure 3 As shown, the first exhaust port 311 is preferably formed in a circle of a preset size (e.g., a diameter of 1.5 to 2.5 cm) at the lower end of the lower housing 310, and most preferably in a circle with a diameter of 2 cm.

[0062] Although Figure 3 The first exhaust port 311 is shown to have a circular shape as an example of one embodiment of the present invention. However, the first exhaust port 311 can be modified and implemented into various polygonal shapes, including rectangles, pentagons, etc., in addition to being circular. The present invention is not limited thereto.

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

[0064] The fixing part 312 protrudes from a region of the lower housing 310 to fix the valve described later. Figure 3 As shown, the fixing part 312 is formed at the upper end of the first exhaust port 311, and multiple fixing parts 312 can be formed within the diameter range of the first exhaust port 311.

[0065] Accordingly, it can be understood that by coupling one area of ​​the valve to the fixing part 312, one area of ​​the valve is fixed to the lower housing 310.

[0066] At the same time, such as Figure 3 and Figure 4 As shown, a first through hole 315 is formed at the upper end of the lower housing 310. The first through hole 315, by being formed to penetrate the mask body, can be understood as a channel for the movement of part of the exhaled air generated by the wearer of the mask body.

[0067] In this case, such as Figure 3 and Figure 4 As shown, the first through hole 315 is preferably provided as a plurality; however, it may also be formed as a single hole, and its shape and size may be changed as needed, and the present invention is not limited thereto.

[0068] refer to Figure 4The valve 320 is formed to be larger than the first exhaust port 311 and includes a formed hole 321 in its upper region. The valve 320 is mounted by inserting the hole 321 into and securing it to a fixing portion 312 protruding from the region of the lower housing 310, thereby obscuring the first exhaust port 311. The region of the valve 320 other than the fixing area is configured to move according to the wearer's breathing, thereby controlling the opening and closing of the first exhaust port 311.

[0069] Furthermore, the valve 320 is formed to be larger than the first exhaust port 311 in order to completely cover the first exhaust port 311. It should be understood that the hole 321 is formed to correspond to the cross-sectional shape and number of the fixing part 312 in order to facilitate insertion and fixation to the fixing part 312.

[0070] In this configuration, the valve 320 is set such that when the wearer exhales through their mouth and nose, the freely movable portion of the valve 320 relative to a fixed area separates from the first exhaust port 311, allowing exhaled air to escape through the first exhaust port 311. Conversely, when the wearer inhales through their mouth and nose, the valve 320 blocks the first exhaust port 311 to prevent the inhalation of outside air.

[0071] Furthermore, it should be understood that the exhaled air discharged through the first exhaust port 311 is subsequently discharged to the outside via the second exhaust port formed in the upper housing and the third exhaust port formed in the intermediate housing, both of which will be described later.

[0072] Specifically, such as Figure 7 As shown in (b), based on the wearer's exhalation, the unsecured lower portion of the valve 320 moves outward relative to the secured upper portion, away from the mask body 100 and the first exhaust port 311. As the valve 320 separates from the first exhaust port 311, the wearer's exhalation is discharged from the interior of the mask body 100 through the first exhaust port 311. Figure 7 As shown in (a), depending on the wearer's inhalation, the lower part of the valve 320, which is not fixed, moves back to the first exhaust port 311 to cover the first exhaust port 311, thereby preventing the inhalation of outside air.

[0073] In other words, exhalation is the process of air being expelled from the wearer and moving outwards, while inhalation is the process of the wearer inhaling external air. Therefore, when the valve 320 is opened due to the wearer's exhalation, the water vapor and carbon dioxide contained in the exhalation are discharged through the first exhaust port 311. When the valve 320 covers the first exhaust port 311 during the wearer's inhalation, it can prevent harmful external substances from being inhaled through the first exhaust port 311.

[0074] Furthermore, despite Figure 7 It is not shown in the figure, but it is preferably understood that the wearer's exhalation through the first exhaust port 311 is discharged to the outside through the third exhaust port formed in the intermediate housing 330 and the second exhaust port formed in the upper housing 340.

[0075] At the same time, such as Figure 3 As shown, a cross-shaped support 3111 may be formed inside the first exhaust port 311. In this case, it can be understood that the support 3111 serves to prevent the valve 320 from being inhaled into the mask body due to the wearer's breathing.

[0076] The shape of the bracket 3111 can be modified or changed to any form as long as it does not interfere with the function of the first exhaust port 311, wherein the first exhaust port 311 is configured to allow the wearer's exhalation and the movement of oxygen generated from the oxygen-generating element (described in detail below) and delivered to the wearer, but the present invention is not limited thereto.

[0077] Back Figure 2 After the valve 320 is fixed to the lower housing 310, the upper housing 340, which is sequentially inserted with the oxygen generation element 400 and the intermediate housing 330, can be coupled with the lower housing 310 to form an integral exhaust unit 300.

[0078] like Figure 1 and Figure 2 As shown, the upper housing 340 is coupled to the lower housing 310, and a second exhaust port 341 can be formed in the side and lower regions of the upper housing for discharging the wearer's exhaled air to the outside.

[0079] The oxygen-generating element 400 can be inserted into the upper housing 340. After the oxygen-generating element 400 is inserted, the intermediate housing 330 is inserted into the upper housing 340 to fix the oxygen-generating element 400.

[0080] Specifically, such as Figure 2 As shown, after the oxygen-generating element 400 is inserted therein, the intermediate housing 330 is inserted into the inner side of the upper housing 340 to fix the oxygen-generating element 400. Figure 5 As shown, a second through hole 331 is formed at the position corresponding to the first through hole 315 of the lower housing 310. A third vent 332, with a shape corresponding to the second vent 341 of the upper housing 340, is formed on both sides and the lower end of the intermediate housing 330. Furthermore, a valve fixing part 333 protrudes from the lower surface region of the intermediate housing 330 to fix the upper end of the valve 320.

[0081] In this case, when the intermediate housing 330 is coupled to the upper housing 340, it is preferable to arrange the second exhaust port 341 of the upper housing 340 and the third exhaust port 332 of the intermediate housing 330 on the same straight line.

[0082] More specifically, the third exhaust port 332 of the intermediate housing 330 is formed in a shape corresponding to the second exhaust port 341 of the upper housing 340, and is aligned with the second exhaust port 341 to form a single channel. Accordingly, it can be understood that when the wearer exhales through the first exhaust port 311 formed through the mask body and the lower housing 310, the gas is subsequently discharged to the outside via the third exhaust port 332 and the second exhaust port 341.

[0083] Therefore, it is preferable to understand that the shapes and positions of the second exhaust port 341 and the third exhaust port 332 correspond to each other, so as to promote the smooth exhalation of the wearer.

[0084] As an embodiment of the present invention, although the accompanying drawings only exemplarily show that the second and third exhaust ports have a hexagonal shape, they can be modified and implemented into various polygonal shapes including rectangles, pentagons, or circles, and the present invention is not limited thereto.

[0085] At the same time, such as Figure 2 As shown, a second through hole 331 is formed in the upper end of the intermediate housing 330 and extends through it. The number and shape of the second through holes 331 correspond to the first through hole 315 in the lower housing 310. Therefore, it can be understood that a portion of the exhaled air produced by the wearer of the mask enters through the first through hole 315 and passes through the second through hole 331, thereby being transmitted to the oxygen-generating element 400 inserted between the upper housing 340 and the intermediate housing 330.

[0086] In this case, such as Figure 2 As shown, the second through hole 331 is preferably provided as a plurality; however, they may also be formed as a single hole, and their shape and size may be changed as needed, and the present invention is not limited thereto.

[0087] Back Figure 5 The valve fixing part 333 formed in the intermediate housing 330 can be formed in a T-shape. Accordingly, it is preferred to understand that: the upper part of the valve fixing part 333 vertically fixes the upper end of the valve 320, while the lower part of the valve fixing part 333 contacts a region of the bracket 3111 formed in the first exhaust port 311, thereby stably fixing the upper end of the valve 320.

[0088] At the same time, such as Figure 2As shown, the oxygen-generating element 400 is inserted into the area within the exhaust unit to generate oxygen by inducing a chemical reaction when it receives breath water vapor and carbon dioxide produced by the wearer's breathing.

[0089] Specifically, a through-hole is formed in the area penetrating the mask body 100 and the exhaust unit 300. Part of the wearer's exhalation (which would normally be expelled to the outside through the exhaust port of the exhaust unit 300) is transmitted through the through-hole to the oxygen-generating element 400 inserted within the exhaust unit to generate oxygen. It should be understood that when the wearer inhales through their mouth and nose, the oxygen generated from the oxygen-generating element 400 is resupplyed to the wearer through the through-hole.

[0090] In this case, as described above, 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.

[0091] In one or more embodiments, the first through-hole 315 formed in the lower housing 310 and the second through-hole 331 formed in the intermediate housing 330 are aligned in a straight line. Therefore, when the wearer exhales through their mouth and nose, a portion of the exhaled air is transferred from inside the mask body to the oxygen-generating element 400 via the first through-hole 315 and the second through-hole 331. When the wearer inhales through their mouth and nose, oxygen generated from the oxygen-generating element 400 can be supplied to the wearer inside the mask body via the second through-hole 331 and the first through-hole 315.

[0092] More specifically, the oxygen-generating element 400 is inserted between the upper housing 340 and the intermediate housing 330 of the exhaust unit. It receives a portion of the wearer's exhaled breath through a first through-hole 315 in the lower housing 310 and a second through-hole 331 in the intermediate housing 330. Subsequently, the oxygen-generating element 400 produces oxygen by inducing a chemical reaction with the water vapor and carbon dioxide contained in the exhaled breath. It should be understood that the produced oxygen is resupplyed to the wearer through the second through-hole 331 and the first through-hole 315 when the wearer inhales.

[0093] Simultaneously, the oxygen-generating element 400 is secured by being inserted into the upper housing 340 and the intermediate housing 330 to prevent it from detaching. Furthermore, by maintaining a sealed state except for the area adjacent to the second through-hole 331 formed in the intermediate housing 330, it is prevented from contacting external moisture and carbon dioxide (except for the wearer's exhalation). This produces the effect of preventing the generation of unnecessary excess oxygen, thereby preventing side effects such as hyperventilation, oxygen toxicity, headaches, and dizziness in the wearer.

[0094] Back Figure 3 and Figure 4 The aforementioned lower housing 310 may include a partition portion 314 for vertically separating the areas within the exhaust unit.

[0095] Specifically, the partition portion 314 can be understood as protruding from the upper surface region of the lower housing 310 and forming in the region between the first through hole 315 and the fixing portion 312.

[0096] Accordingly, in one or more embodiments, when the upper housing 340, into which the intermediate housing 330 is inserted, is coupled to the lower housing 310, as... Figure 7 As shown, the protruding end of the partition portion 314 is in close contact with the lower end of the second through hole 331 formed in the intermediate housing 330, thereby vertically separating the space between the lower housing 310 and the intermediate housing 330.

[0097] In this configuration, since the space between the lower housing 310 and the middle housing 330 is vertically separated by the partition portion 314, a portion of the wearer's exhalation is transmitted to the oxygen-generating element 400 through the first through-hole 315 and the second through-hole 331 formed on the upper part of the exhaust unit. The remaining exhalation is discharged to the outside through the first to third exhaust ports formed on the lower part of the exhaust unit. By regulating the amount of exhalation transmitted to the oxygen-generating element 400 in this manner, the oxygen-generating efficiency of the oxygen-generating element 400 can be improved. This further improves the breathing environment for the wearer of the dust mask of the present invention and prevents air pollution inside the mask body 100.

[0098] Furthermore, by vertically dividing the area within the exhaust unit, oxygen generated by the oxygen-generating element 400 is directly delivered to the wearer via a first through-hole 315 and a second through-hole 331 formed in the upper part of the exhaust unit. This prevents oxygen from leaking to the outside, thereby ensuring an effective supply of oxygen to the wearer.

[0099] Also refer to Figure 2 , Figure 3 and Figure 6 The lower housing 310 includes a protrusion 313 and a coupling groove 3131 formed along its outer peripheral surface. The upper housing 340 may include a coupling protrusion 342 protruding from its lower end for insertion into the coupling groove 3131.

[0100] Therefore, it can be understood that when the coupling protrusion 342 of the upper housing 340 is inserted into the coupling groove 3131 of the lower housing 310, an exhaust unit is formed. At the same time, the lower end of the intermediate housing 330 inserted in 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 onto the protrusion 313.

[0101] In this case, it is preferred to understand that: valve 320 is located between lower housing 310 and intermediate housing 330, and first exhaust port 311 is located behind valve 320. In addition, oxygen generating element 400 is located between intermediate housing 330 and upper housing 340.

[0102] In other words, such as Figure 2 As shown, the lower housing 310, valve 320, intermediate housing 330, oxygen generating element 400 and upper housing 340 are coupled in sequence to form an exhaust unit 300 containing the oxygen generating element 400.

[0103] Also refer to Figure 7 and Figure 8 The oxygen-generating element 400 is configured to generate oxygen by receiving water vapor and carbon dioxide contained in the wearer's exhalation, and may include an oxygen-generating compound 410 and a bag body 420.

[0104] The oxygen-producing compound 410 generates oxygen by reacting with a reactant comprising at least one of water vapor and carbon dioxide. The oxygen-producing compound 410 may be formed by mixing the following components: an oxidant comprising at least one of potassium superoxide (KO2) and sodium peroxide (Na2O2); a stabilizer comprising at least one or a combination of 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 predetermined proportion.

[0105] In this case, the potassium superoxide exists as a yellow solid and is produced by heating potassium in a glass tube for an extended period while dry air is introduced. Potassium superoxide is known as a strong oxidizing agent, as shown in reaction formula 1, which reacts with water to release oxygen and produce potassium hydroxide (KOH).

[0106] Sodium peroxide exists as yellowish-white granules or powder and is also known as sodium dioxide. As an oxidizing agent, it reacts with water to produce sodium hydroxide (NaOH) and oxygen, as shown in reaction formula 2.

[0107] Meanwhile, potassium superoxide can react with carbon dioxide to release oxygen and produce potassium carbonate, as shown in reaction formula 3; sodium peroxide can react with carbon dioxide to release oxygen and produce sodium carbonate, as shown in reaction formula 4.

[0108] Therefore, in this invention, it is preferred to understand that oxygen is produced by reacting oxygen-producing compound 410 with a reactant containing at least one of water vapor (H2O) and carbon dioxide (CO2) produced by the wearer's breathing.

[0109] Meanwhile, the oxygen-generating compound 410 in this invention includes a stabilizer composed of alkaline earth metal hydroxides to stabilize its reactivity when the oxidant (potassium superoxide and sodium peroxide) reacts with the reactants. The stabilizer includes at least one selected from calcium hydroxide (Ca(OH)2), aluminum hydroxide (Al(OH)3), and magnesium hydroxide (Mg(OH)2).

[0110] In this context, calcium hydroxide is a white, powdery, alkaline compound. Although its solubility in water is low (only about 0.82g dissolves in 1L of water), it has a high degree of ionization (dissociation). Therefore, calcium hydroxide dissolved in water exhibits strong alkalinity, with a pH of approximately 12.5.

[0111] Furthermore, when calcium hydroxide reacts with carbon dioxide (CO2), calcium carbonate is produced via the following reaction (see reaction 5). The calcium carbonate thus produced reacts with carbon dioxide and moisture contained in the air or human breath to form calcium bicarbonate (see reaction 6), which can be effectively used to treat carbon dioxide.

[0112] Aluminum hydroxide, as a hydroxide of aluminum, is an amphoteric hydroxide. It reacts with acids to form aluminum salts and with bases to become aluminates. In particular, it gels upon prolonged contact with water, and the gelled aluminum hydroxide exhibits strong adsorption properties.

[0113] Magnesium hydroxide exists in nature as brucite. When an alkali metal hydroxide is added to a magnesium salt, a colorless colloidal precipitate is formed. Furthermore, when this solid is exposed to air, it can absorb carbon dioxide and convert it into magnesium carbonate, which is very useful for carbon dioxide control.

[0114] Meanwhile, the oxygen-generating compound 410 of the present invention may include silica gel and carrageenan, both of which have hygroscopic properties, to absorb moisture generated during the chemical reaction between the components of the oxygen-generating compound 410 (oxidant and stabilizer) and reactants containing at least one of water vapor (H2O) and carbon dioxide (CO2) produced by the wearer's respiration.

[0115] The silica gel is a glossy, granular, porous material primarily composed of silicon dioxide (SiO2). Due to its porous structure, it possesses a large surface area of ​​approximately 800 m² / g, thus providing excellent moisture absorption. The micropores on the silica gel surface provide space to hold moisture, thereby adsorbing moisture from the air.

[0116] Carrageenan is a polysaccharide extracted from red algae (red or purple seaweed that inhabits coastal waters) and is widely used as a thickener, stabilizer, and gelling agent. Due to its property of absorbing water and gelling, it helps retain moisture and prevents it from being released.

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

[0118] Simultaneously, the bag body 420 is formed into a film shape with a predetermined size for containing the oxygen-generating compound 410 therein. The bag body 420 may be formed of at least one material selected from the group consisting of Tyvek, elastic nonwoven fabric, polyamide, and polyethylene terephthalate.

[0119] In this case, the bag 420 is preferably formed of a material with high porosity to allow water vapor and carbon dioxide contained in the wearer's exhalation to be transferred to the oxygen-producing compound 410 inside the bag 420, and to allow oxygen generated from the oxygen-producing compound 410 to be released to the outside of the bag 420.

[0120] Meanwhile, the materials constituting the aforementioned bag body 420 are described in detail below.

[0121] Tyvek is a synthetic material made of high-density polyethylene fibers. Because it is bonded without adhesives, it forms micropores, providing excellent breathability, allowing moisture to permeate the material while preventing the passage of water or other liquids. Furthermore, its continuous structure of long fibers provides a self-protective microbial barrier, effectively blocking harmful substances such as asbestos, mold, fiberglass, and lead, while also exhibiting high durability and resilience.

[0122] Elastic nonwoven fabrics are produced by coating part or all of the surface of a stretchable nonwoven fabric with an elastic polymer in the form of a thin film, thereby forming an elastic nonwoven network on the surface. This material offers excellent elasticity and resilience.

[0123] Polyamide is a thermosetting or thermoplastic amorphous polymer with excellent mechanical, thermal, and chemical resistance. It is widely used in fibers, films, and electrical insulations. Especially when used as a fiber, its good durability, chemical stability, and elasticity make it primarily used in clothing or industrial materials.

[0124] Polyethylene terephthalate (PET) is a plastic material polymerized from ethylene glycol and terephthalic acid. Due to its good durability, chemical stability, and recyclability, it is considered an environmentally friendly material.

[0125] In one or more embodiments, an oxygen-generating element 400, formed by injecting the oxygen-generating compound 410 into a thin-film bag 420 made of the aforementioned material, can be inserted between the upper housing 340 and the intermediate housing 330 of the exhaust unit.

[0126] Furthermore, based on test results of the oxygen-generating element 400 of this invention using EPA 9045D, EPA 6020, EPA 8081A, and EPA 8260B GCMS testing methods (these are environmental pollutant analysis testing methods established by the U.S. Environmental Protection Agency (EPA), it was confirmed that its pH value is greater than 12, and no volatile organic compounds (VOCs) or pesticides were detected, thus confirming its chemical stability. In addition, it has been proven to help remove coronaviruses, kill bacteria, fight bacteria, deodorize, provide fragrance, and supply oxygen, and has therefore obtained an FDA NDC registration certificate.

[0127] The following will combine Figure 7 and Figure 8 The invention describes the transport path of water vapor and carbon dioxide generated by the breathing of a wearer wearing the dust mask of the present invention, the operation process of the exhaust unit, and the process of the oxygen generation element generating oxygen and delivering it to the wearer.

[0128] First, such as Figure 7 As shown in (a), the dust mask of the present invention may include an exhaust unit formed on the outer surface of the mask body 100. The exhaust unit is configured by sequentially coupling a lower housing 310, a valve 320, an intermediate housing 330 and an upper housing 340, and an oxygen generating element 400 is inserted between the intermediate housing 330 and the upper housing 340.

[0129] When the wearer of the dust mask of this invention exhales, such as Figure 7 As shown in (b), the valve 320, which originally blocked the first exhaust port 311 (which penetrates the mask body 100 and the lower shell 310), moves due to the wearer's exhalation containing water vapor (H2O) and carbon dioxide (CO2). This action opens the first exhaust port 311, allowing exhaled air to escape through it. Although Figure 7 It is not explicitly shown, but the gas can then be discharged to the outside via a third exhaust port (not shown) formed in the middle housing of the exhaust unit and a second exhaust port (not shown) formed in the upper housing.

[0130] Specifically, such as Figure 7As shown in (b), when the wearer of the mask body 100 exhales through their mouth and nose, the lower part of the valve 320, which is freely movable relative to the fixed area, separates from the first exhaust port 311. This separation opens the first exhaust port 311 through which exhaled air is discharged, and it is preferably understood that the gas is subsequently discharged to the outside via the third exhaust port and the second exhaust port of the exhaust unit.

[0131] At the same time, while exhalation is discharged through the first exhaust port 311, it should be understood that part of the exhalation generated by the wearer is transmitted to the oxygen generating element 400 inserted between the upper shell 340 and the middle shell 330 through the first through hole 315 formed through the mask body 100 and the lower shell 310, and the second through hole 331 formed through the middle shell 330.

[0132] Furthermore, when part of the wearer's exhalation is delivered to the oxygen-generating element 400, the water vapor and carbon dioxide contained in the exhalation pass through the porous material bag 420 of the oxygen-generating element 400 and are delivered to the oxygen-generating compound 410 therein. It can be understood that oxygen is produced through a chemical reaction between water vapor, carbon dioxide, and the oxygen-generating compound 410.

[0133] At the same time, such as Figure 8 As shown, when a wearer wearing the mask body 100 inhales, oxygen generated from the oxygen-generating element 400 enters the interior of the mask body 100 through the second through hole 331 of the intermediate shell 330 and the first through hole 315 penetrating the mask body 100 and the lower shell 310. Therefore, it can be understood that oxygen is supplied to the wearer, enabling them to inhale oxygen into their body.

[0134] On the other hand, because the wearer's exhaled breath contains water vapor, carbon dioxide, etc., it has the characteristics of high density and high temperature. Therefore, such as Figure 7 As shown in (b), when the wearer exhales, valve 320 moves to open the first exhaust port 311. When exhaled air is discharged through the opened first exhaust port 311, the air density and temperature inside the mask body 100 decrease, and a low-pressure state may be formed.

[0135] Therefore, due to the low pressure formed inside the mask body 100, oxygen generated from the oxygen-generating element 400 can move into the mask body 100 through the second through hole 331 and the first through hole 315, thereby supplying it to the wearer.

[0136] In addition, while oxygen is supplied from the oxygen-generating element 400 through the wearer's inhalation or the low pressure formed inside the mask body, the lower end of the valve 320, which is not fixed, moves back to the first exhaust port 311 due to the wearer's inhalation to cover the first exhaust port 311, thereby preventing the inhalation of outside air.

[0137] As a result, when the wearer inhales, the first exhaust port 311 of the exhaust unit is blocked to prevent harmful external air from being transmitted to the wearer through the exhaust unit. At the same time, oxygen can be supplied from the oxygen-generating element 400, thereby protecting the wearer's respiratory system from harmful substances generated in the industrial environment and promoting smooth breathing.

[0138] Furthermore, since the partition portion 314 formed in the lower housing 310 is in close contact with the inner side of the intermediate housing 330, the space between the lower housing 310 and the intermediate housing 330 is vertically separated. This configuration prevents oxygen generated by the oxygen-generating element 400 from leaking to the outside through the second and third exhaust ports formed in the exhaust unit. Instead, oxygen generated in the oxygen-generating element 400 is directly delivered to the wearer through the first and second through holes formed in the upper part of the exhaust unit, thereby improving oxygen supply efficiency.

[0139] In other words, the dust mask of this invention allows the wearer to control the opening and closing of the exhaust unit through breathing, including exhalation and inhalation. The area within the exhaust unit is vertically divided by a partition, allowing the upper space to transmit the wearer's exhalation to the oxygen-generating element and serve as a channel for the movement of the generated oxygen; simultaneously, the lower space of the exhaust unit serves as a channel for the wearer's exhalation to escape to the outside. This configuration improves the wearer's breathing environment, prevents air pollution inside the mask body, and enables prolonged breathing even without an independent external oxygen supply.

[0140] The following will refer to Figures 9 to 13 This describes an industrial dust mask comprising an oxygen-generating element according to another embodiment of the present invention.

[0141] In another embodiment of the invention, such as Figure 9 and Figure 10 As shown, the exhaust unit may include a first housing 500 and a second housing 600.

[0142] The first housing 500 performs the same function as the aforementioned lower housing 310. The first housing 500 is formed in the region of the mask body 100 corresponding to any position in the wearer's mouth and nose. A fourth exhaust port 510 penetrating the mask body 100 is formed in the lower end region of the first housing 500 to allow the wearer's exhaled air to escape. The first housing 500 may include a valve 520 configured to cover the fourth exhaust port 510.

[0143] In this case, it should be understood that the fourth exhaust port 510 performs the same function as the aforementioned first exhaust port. Specifically, the fourth exhaust port 510 is formed at a predetermined size at any location corresponding to the wearer's mouth and nose. For example, the size of the fourth exhaust port 510 may be approximately 1 mm, and as... Figure 9As shown, multiple fourth exhaust ports 510 can be formed to ensure ventilation effect.

[0144] Furthermore, the number and size of the fourth exhaust port 510 according to another embodiment of the present invention can be changed or modified as needed, and the present invention is not limited thereto.

[0145] Simultaneously, valve 520 controls the opening and closing of the fourth exhaust port 510 through the wearer's breathing. For example... Figure 9 As shown, the area formed by valve 520 is larger than the area formed by the fourth exhaust port 510. An area at the upper or lower end of valve 520 is fixed to the outer surface of the mask body 100, such that valve 520 obscures the fourth exhaust port 510. It should be understood that the area of ​​valve 520 other than the fixed area can move according to the wearer's breathing, thereby controlling the opening and closing of the fourth exhaust port 510.

[0146] Specifically, refer to Figure 12 The valve 520 is configured such that when the wearer exhales through their mouth and nose, the freely movable portion of the valve 520 relative to the fixed area separates from the fourth exhaust port 510 to allow exhalation to pass through the fourth exhaust port 510. When the wearer inhales through their mouth and nose, the valve 520 blocks the fourth exhaust port 510 to prevent the inhalation of outside air.

[0147] In other words, such as Figure 12 As shown in (b), the unsecured portion of valve 520 moves outward away from the mask body 100 according to the wearer's exhalation. As valve 520 separates from the fourth exhaust port 510, the wearer's exhalation is discharged through the fourth exhaust port 510. Conversely, as... Figure 12 As shown in (a), depending on the wearer's inhalation, the unsecured portion of valve 520 moves back to the fourth exhaust port 510 to block the fourth exhaust port 510, thereby preventing the inhalation of outside air.

[0148] In other words, since exhalation is the process of air being expelled from the wearer and moving outward, while inhalation is the process of the wearer inhaling external air, when valve 520 is opened due to the wearer's exhalation, the water vapor and carbon dioxide contained in the exhalation are discharged through the fourth exhaust port 510. When valve 520 covers the fourth exhaust port 510 during the wearer's inhalation, it can prevent harmful external substances from being inhaled through the fourth exhaust port 510.

[0149] In another embodiment of the invention, such as Figure 9 As shown, it is preferred to understand that the number of valves 520 corresponds to the number of fourth exhaust ports 510. However, multiple fourth exhaust ports 510 can also be opened and closed using a single valve 520. In this case, it is preferable to make the valve 520 large enough to cover all of the multiple fourth exhaust ports 510, and the invention is not limited thereto.

[0150] At the same time, it is understandable that the function performed by the aforementioned valve 520 is the same as... Figure 8 The valve 320 shown in the embodiment of the present invention is the same.

[0151] Back Figure 9 A first coupling portion 530 may be formed in the first housing 500 for coupling with the second housing described later.

[0152] Specifically, the first coupling portion 530 is formed along the outer peripheral surface of the region where the fourth exhaust port 510 and valve 520 are formed. It is formed to be larger than the size of valve 520 so that a region of the second housing can be coupled thereto.

[0153] In this case, it is preferable to couple the first coupling portion 530 to the corresponding region of the second housing by means of a fitting. However, any coupling method can be used as long as the second housing can be coupled 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 couples with the second housing, the valve 520 moves according to the wearer's exhalation and opens the fourth exhaust port 510. This can be understood as the wearer's exhalation moving from the inside of the mask body 100 to the outside and simultaneously being transferred to the second housing, thereby generating oxygen in the second housing.

[0155] In another embodiment of the invention, such as Figures 10 to 13 As shown, the second housing 600 is coupled to the first housing 500 and includes a receiving space 610 for accommodating an oxygen-generating element 400, which produces oxygen through a chemical reaction with water vapor and carbon dioxide generated by the wearer's respiration. Specifically, the receiving space 610 is formed in its upper region, while a fifth exhaust port 620 is formed in its lower region for discharging the wearer's exhaled air from the fourth exhaust port 510 of the first housing 500 to the outside. A through hole 621 may be formed between the lower end of the receiving space 610 and the upper end of the fifth exhaust port 620.

[0156] In this case, the second housing 600 can be understood to have a form similar to the combination of the upper housing and the middle housing in the aforementioned embodiments. Furthermore, the fifth exhaust port 620 serves to expel the wearer's exhaled air to the outside, similar to the second and third exhaust ports described in the aforementioned embodiments.

[0157] A fifth exhaust port 620 extends from one side to the other of the second housing 600 adjacent to the first housing 500. For example... Figure 10 and Figure 11 As shown, multiple such exhaust ports can be formed to effectively expel exhaled air.

[0158] like Figure 11 and Figure 12 As shown, a through-hole 621 is formed between and through the fifth exhaust port 620 and the receiving space 610. Its purpose is to allow a portion of the wearer's exhalation, which would normally be discharged through the fourth exhaust port 510 and then through the fifth exhaust port 620, to be delivered to the receiving space 610 where the oxygen-generating element 400 is placed. Therefore, the through-hole 621 serves as a partial exhalation path.

[0159] Accordingly, the wearer's exhaled breath moves through the through-hole 621 to the oxygen-generating element 400 held within the receiving space 610. Subsequently, as the water vapor and carbon dioxide in the exhaled breath chemically react with the oxygen-generating compound 410, oxygen is produced. It should be understood that the produced oxygen returns through the through-hole 621 and is delivered to the wearer's respiratory system via the fourth exhaust port 510.

[0160] In another embodiment of the invention, such as Figures 11 to 13 As shown, the second housing 600 may include an oxygen-generating element insertion portion 630 and a second coupling portion 640.

[0161] like Figure 11 As shown, the oxygen-generating element insertion portion 630 is formed in the second housing 600 at a position corresponding to the receiving space 610, allowing the oxygen-generating element 400 to be inserted into the receiving space 610 from the outside.

[0162] Preferably, the oxygen-generating element insertion portion 630 is formed in a circular shape so that the thin-film oxygen-generating element 400 can be rolled up and inserted. It should be understood that once the rolled-up oxygen-generating element 400 is inserted into the receiving space 610 within the second housing 600, it will unroll back from a rolled shape to a thin-film shape due to its shape-restoring force, thereby being fixed within the receiving space 610.

[0163] Meanwhile, it can be understood that the oxygen-generating element 400 according to this embodiment has the same configuration and function as the oxygen-generating element in the foregoing embodiments.

[0164] Specifically, the oxygen-generating element includes an oxygen-generating compound 410 and a bag body 420. The bag body may be formed from at least one material selected from Tyvek, elastic nonwoven fabric, polyamide, and polyethylene terephthalate. Because these materials have shape-restoring properties, it should be understood that they can return to their initial shape even after deformation.

[0165] Therefore, as Figure 11 As shown, when the rolled-up oxygen-generating element 400 is inserted through the insertion part 630, the shape-restoring force of the bag body 420 causes the element to expand and be fixed within the receiving space 610 of the second housing 600, as... Figure 12 As shown.

[0166] Therefore, by rolling the thin-film oxygen generating element 400 into a roll for insertion and allowing it to return to its film shape after entering the interior, the oxygen generating element 400 can be effectively prevented from falling off or escaping from the second housing 600.

[0167] Although not shown in the accompanying drawings, another embodiment of the invention may further include a retaining cover (not shown) capable of sealing the receiving space for housing the oxygen-generating element. Specifically, the retaining cover is formed to shield the insertion portion of the oxygen-generating element, which extends from the outer surface region of the second housing into the receiving space.

[0168] After the oxygen-generating element is rolled into a coil and inserted through the insertion part, a fixing cap with a shape corresponding to the insertion part is then inserted. By sealing the receiving space in this way, the oxygen-generating element can be prevented from falling out of the receiving space within the second housing, and the oxygen generated by the element can be prevented from leaking to the outside.

[0169] Back Figure 12 A second coupling portion 640 is formed on a surface of the second housing 600 adjacent to the mask body 100, so as to couple the second housing 600 to the first housing 500 formed on the mask body 100. Preferably understood as follows: Figure 9 and Figure 12 As shown, the second coupling portion 640 is shaped to be able to couple with the first coupling portion 530 of the first housing 500.

[0170] like Figure 12 As shown, the second coupling part 640 is preferably coupled to the first coupling part 530 via a fitting connection. However, in addition to the fitting method, any coupling method can be used as long as the second housing 600 can be stably coupled to the first housing 500 and kept fixed, and the present invention is not limited thereto.

[0171] The following will refer to Figure 12 and Figure 13 This describes the transport path of water vapor and carbon dioxide generated by the wearer's breathing in an industrial dust mask according to another embodiment of the present invention, the operation process of the valve, and the process by which an oxygen-generating element inserted in the second housing generates oxygen and delivers it to the wearer.

[0172] First, according to another embodiment of the invention, the second housing allows the wearer's exhaled air to be discharged from the fourth exhaust port through the fifth exhaust port. Simultaneously, it delivers the exhaled air to the receiving space where the oxygen-generating element is housed to produce oxygen. As the exhaled air is discharged through the fourth and fifth exhaust ports, a low-pressure state is created in the area between these exhaust ports, allowing the oxygen generated by the oxygen-generating element to be supplied to the wearer through the fourth exhaust port.

[0173] Specifically, the wearer's exhaled breath contains water vapor, carbon dioxide, etc., and therefore has high density and high temperature. Therefore, as... Figure 12 As shown in (b), when the wearer exhales, valve 520 moves to open the fourth exhaust port 510. When exhaled air is discharged through the opened fourth exhaust port 510, the air density and temperature inside the mask body 100 and in the area between the fourth exhaust port 510 and the fifth exhaust port 620 decrease, thereby creating a low-pressure state.

[0174] More specifically, such as Figure 12 As shown in (b), when the wearer exhales through their mouth and nose, the free-moving portion of valve 520 separates from the fourth exhaust port 510. The exhaled air discharged through the open fourth exhaust port 510 is then discharged to the outside through the fifth exhaust port 620. Simultaneously, air is delivered to the oxygen-generating element 400 disposed in the receiving space 610 through a through hole 621 formed in the second housing 600. It is preferably understood that during this process, the air density and temperature inside the mask body 100 and between the fourth and fifth exhaust ports decrease, resulting in the formation of a low pressure.

[0175] Furthermore, when the wearer exhales through the fourth exhaust port 510 and delivers it to the oxygen-generating element 400, the water vapor and carbon dioxide contained in the breath reach the oxygen-generating compound 410. Therefore, it can be understood that oxygen is produced through a chemical reaction between the oxygen-generating compound 410 and the water vapor and carbon dioxide.

[0176] At the same time, such as Figure 13 As shown, the oxygen generated by the oxygen-generating element 400, at the moment the fourth exhaust port 510 is opened, originates from the receiving space 610 where the oxygen-generating element 400 is housed, passes through the through hole 621 and the fifth exhaust port 620, and then enters the interior of the mask body 100 through the fourth exhaust port 510. This movement is caused by the low pressure generated in the area between the fourth exhaust port 510 and the fifth exhaust port 620, as well as the low pressure formed inside the mask body 100. Therefore, it can be understood that oxygen is supplied to the wearer.

[0177] In addition, when oxygen is supplied to the wearer, the wearer inhales the oxygen into their body through inhalation, and at the same time, such as Figure 12 As shown in (a), the unsecured portion of valve 520 is moved back to the fourth exhaust port 510 to cover the fourth exhaust port 510, which is understood to prevent the intake of outside air.

[0178] In other words, according to another embodiment of the present invention, an industrial dust mask including an oxygen-generating element generates oxygen by delivering the wearer's exhalation to the oxygen-generating element through a fourth exhaust port formed on a first shell on the mask body, and a fifth exhaust port and a through hole of a second shell coupled to the first shell. When the oxygen generated by the oxygen-generating element is delivered to the wearer through the low pressure inside the mask body and the low pressure in the area between the fourth and fifth exhaust ports formed by the wearer's exhalation, the wearer inhales the delivered oxygen. Preferably, the valve blocks the fourth exhaust port through the wearer's inhalation action, thereby preventing harmful external air from being delivered to the wearer through the fourth and fifth exhaust ports.

[0179] In summary, according to the embodiments of the present invention described above, an industrial dust mask comprising an oxygen-generating element of the present invention achieves the simultaneous discharge of the wearer's exhaled air to the outside through the exhaust unit and the transfer of a portion of the exhaled air to the oxygen-generating element to generate oxygen. By allowing the wearer to receive oxygen generated by the oxygen-generating element during inhalation, the mask effectively protects the wearer's respiratory system from harmful substances generated in industrial environments and promotes smooth breathing by supplying oxygen.

[0180] Furthermore, according to one embodiment of the present invention, by adding silica gel and carrageenan, which have excellent hygroscopic capacity, to the oxygen-generating compound constituting the oxygen-generating element in addition to the oxidant and stabilizer, moisture generated during oxygen generation can be absorbed. This has the effect of preventing low-temperature burns caused by moisture generated during the oxygen-generating process of the oxygen-generating compound.

[0181] Furthermore, according to one embodiment of the present invention, the oxygen-generating element has significant effects in assisting in the removal of coronaviruses, sterilization, antibacterial properties, deodorization, and the provision of fragrance and oxygen. Therefore, by applying the oxygen-generating element of the present invention to a dust mask, multiple effects such as virus removal, sterilization, antibacterial properties, deodorization, and the supply of fragrance and oxygen can be provided to the wearer while blocking harmful substances in industrial environments.

[0182] Furthermore, according to one embodiment of the present invention, by making the oxygen-generating element into the form of a thin film, the size of the exhaust unit into which the oxygen-generating element is inserted can be effectively reduced, thereby providing convenience for wearers of dust masks.

[0183] Furthermore, according to one embodiment of the invention, the internal region of the exhaust unit is vertically divided by a partition. Therefore, a portion of the wearer's exhalation is delivered to the oxygen-generating element through first and second through-holes formed in the upper part of the exhaust unit, while the remaining exhalation is discharged to the outside through first to third exhaust ports formed in the lower part. This regulates the amount of exhalation delivered to the oxygen-generating element, thereby improving oxygen production efficiency, improving the wearer's breathing environment, and preventing air pollution inside the mask body.

[0184] Furthermore, according to one embodiment of the invention, by vertically dividing the area within the exhaust unit, oxygen generated by the oxygen-generating element is directly delivered to the wearer through the upper first and second through holes. This prevents oxygen leakage to the outside and ensures an effective oxygen supply to the wearer.
