Description

Technical Field

[0001] The invention relates to a life-saving towel which can generate oxygen in case of a fire or other critical situation, thereby maintaining life for a long time and can be used quickly and conveniently in case of a fire. Background Art

[0002] If a disaster such as a fire occurs, people may lose their lives due to the heat generated by the fire, but before that, the toxic gases produced flow into the human respiratory system. Therefore, even if they are not harmed by the fire, more people will die from suffocation due to smoke.

[0003] Therefore, when a fire occurs, it is important to avoid the flames, but what is more important is to prevent the inhalation of smoke containing toxic gases as much as possible in order to survive for a long time, wait for the arrival of rescuers, and ultimately increase the probability of survival.

[0004] In the event of a fire, people in critical situations often use a towel to block their mouths and noses to breathe, or soak a towel in water and then use it to block their mouths and noses to breathe. However, simply soaking a towel in water is not enough to sustain life for long periods of time. Therefore, there is an urgent need for a disaster safety product that can minimize the flow of toxic gases into the human respiratory system while also maintaining life for a longer period of time. Summary of the Invention

[0005] Problems to be solved by the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a life-saving towel that can block the flow of toxic gases into the human respiratory system in disaster situations such as fire, while supplying oxygen to the human respiratory system using an oxygen generator that generates oxygen independently, thereby maintaining life for a long time.

[0007] Another object of the present invention is to provide a life-saving towel that can prevent unnecessary oxygen production and damage to the product when the life-saving towel is not in use.

[0070] The advantages, features, and methods of the present invention will become apparent in conjunction with the accompanying drawings and the embodiments described in detail. However, the present invention is not limited to the embodiments described below and may be implemented in various forms. The purpose of these embodiments is to better illustrate the present invention and facilitate understanding by those skilled in the art. The present invention is limited only by the claims. Throughout this specification, like reference numerals refer to like elements. In the drawings, the sizes and relative sizes of layers and regions may be exaggerated for ease of illustration.

[0071] Terms such as “below,” “beneath,” “lower,” “above,” and “upper” that indicate relative positions in space are used to describe the relationship between one element or component and other elements and components.

[0072] For ease of explanation, terms such as "first" and "second" are used to refer to various elements, but these elements are not limited by these terms. These terms are intended solely to distinguish one element from another. Therefore, within the scope of the present invention, the first element described below may also be the second element.

[0073] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0074] Figure 1 A schematic exploded perspective view of a life-saving towel according to an embodiment of the present invention is shown.

[0075] See Figure 1According to an embodiment of the present invention, a life-saving towel comprises a filter sheet 100; an oxygen-generating container 200, which contains an oxygen-generating substance 10 and contacts and is bonded to one side of the filter sheet 100; an oxygen-generating container barrier frame 250, which contacts the other side of the filter sheet 100 and is bonded to the oxygen-generating container 200 with the filter sheet 100 placed in the middle, forming a plurality of empty spaces inside; and an oxygen-generating cover 300, comprising a bonding portion 350 formed on one side for bonding to the oxygen-generating container barrier frame 250 and contacting the other side of the oxygen-generating container barrier frame 250 to cover all the plurality of spaces of the oxygen-generating container barrier frame 250.

[0076] The oxygen generator container 200 can house the oxygen generator 10. One side is open to allow oxygen generated by the oxygen generator 10 to flow into the user's respiratory system, while the side and bottom portions are closed. Therefore, except for the open side, the other portions of the container can be sealed from the outside, providing a completely sealed structure when not in use with the oxygen generator cover 350.

[0077] The oxygen-generating material 10 may include activated carbon, 5 to 50 parts by weight of a metal peroxide per 100 parts by weight of the activated carbon, and 0.001 to 5 parts by weight of a catalyst. The activated carbon may be at least one selected from the group consisting of coconut, wood, and carbon. The metal peroxide may be at least one selected from the group consisting of calcium peroxide, magnesium peroxide, potassium peroxide, barium peroxide, and sodium peroxide. The catalyst may be at least one selected from the group consisting of a catalyst, catalase, potassium iodide, and manganese dioxide. As described above, the oxygen-generating device 200 may contain the oxygen-generating material 10 for generating oxygen and be sealed. Only when the oxygen-generating cover 300 is removed does the material absorb moisture and carbon dioxide from the air to produce pure oxygen. Therefore, in an emergency, while the user is shielded from harmful external gases through the filter sheet 100, the oxygen-generating material 10 contained within the oxygen-generating device 200 generates oxygen only between the filter sheet 100 and the user's respiratory system, thereby maintaining survival for a long period of time.

[0078] The oxygen-generating container barrier frame 250 can be coupled to the oxygen-generating container 200, contacting the side of the oxygen-generating container 200 that is not coupled to the filter sheet 100. The oxygen-generating container barrier frame 250 is coupled to the oxygen-generating container 200 with the filter sheet 100 positioned between the two sides. Furthermore, the oxygen-generating container barrier frame 250 has multiple holes formed inside to prevent the oxygen-generating substance 10 within the oxygen-generating container 200 from leaking out, further ensuring a more stable interior of the oxygen-generating container 200. Specifically, the oxygen-generating cover 300 is coupled to the oxygen-generating container barrier frame 250, ultimately completely blocking and sealing the oxygen-generating substance 10 from the outside.

[0079] Specifically, the oxygen-generating container barrier frame 250 can be constructed by intersecting frames horizontally to form multiple spaces within the frame. This allows the oxygen-generating cover 300 to be more stably attached to the oxygen-generating container barrier frame 250. In other words, the intersecting frames prevent the central portion of the oxygen-generating cover 300 from sag into the interior of the oxygen-generating container 200, thereby preventing physical damage to the oxygen-generating material 10 or the generation of oxygen that consumes the oxygen-generating material 10. When oxygen is needed, the multiple spaces formed within the intersecting frames allow oxygen to flow into the user's respiratory system.

[0080] The oxygen generator cover 300 is coated on one side with an adhesive portion 350 for bonding to the oxygen generator containment barrier frame 250. Therefore, it is securely bonded not only to the edge of the oxygen generator containment barrier frame 250 but also to the inner frame. This prevents the oxygen generator cover 300 from unintentionally separating and more securely blocks the oxygen-generating material 10 from the outside. When the life-saving towel of the present invention is not used but stored as an emergency item, the adhesive force of the adhesive portion 350 maintains the oxygen generator cover 300 in secure contact with the oxygen generator containment barrier frame 250. In emergencies such as fires, the oxygen generator cover 300 can be removed to generate oxygen from the oxygen-generating material 10 contained within the oxygen generator containment 200. Thus, the filter sheet 100 prevents toxic gases from entering the user's respiratory system through the spaces in the oxygen generator containment barrier frame 250, thereby extending survival time.

[0081] in addition, Figure 2 A schematic exploded perspective view of a life-saving towel according to another embodiment of the present invention is shown. Figure 3 To illustrate the combination Figure 2 Schematic diagram of the connection between the filter sheet of the life-saving towel and the oxygen cover. Figure 4 To illustrate the combination Figure 2 The schematic diagram of the connection between the filter sheet of the life-saving towel and the oxygen cover is to Figure 3 Schematic diagram of the combined thin film viewed from another direction.

[0082] See Figures 2 to 4In a life-saving towel according to another embodiment of the present invention, the oxygen-generating container 200 further includes an oxygen-generating container rib 210 formed on an edge portion; the filter sheet 100 includes a region formed as a space corresponding to the cross-section of the oxygen-generating container 200; and further includes an oxygen-generating container coupling frame 220 having a shape corresponding to the oxygen-generating container rib 210 and forming a space inside the edge portion. The oxygen-generating container 200 allows the oxygen-generating container rib 210 to contact the other side of the filter sheet 100, and the oxygen-generating container 200 passes through the region formed as the space of the filter sheet 100 and is provided on one side of the filter sheet 100; the oxygen-generating container coupling frame 220 is coupled and fixed to the oxygen-generating container rib 210 on one side of the filter sheet 100 in a state of passing through the oxygen-generating container 200 and sandwiching a portion of the filter sheet 100; the oxygen-generating container blocking frame 250 is directly coupled to the other side of the oxygen-generating container rib 210.

[0083] and Figure 1 Differently, according to another embodiment of the present invention, a life-saving towel can be coupled to the filter sheet 100 by placing the oxygen-generating container ribs 210 formed on the oxygen-generating container 200 between the oxygen-generating container coupling frame 220 and the filter sheet 100. Furthermore, the filter sheet 100 includes a region formed as a space corresponding to the cross-section of the oxygen-generating container 200. The oxygen-generating container ribs 210 formed on the edge of the oxygen-generating container 200 are arranged to contact the other side of the filter sheet 100, while the portion of the oxygen-generating container 200 that accommodates the oxygen-generating material 10 is provided on one side of the filter sheet 100 through the space of the filter sheet 100.

[0084] Specifically, the oxygen-generating container 200 is positioned on one side of the filter sheet 100, extending through the space provided by the filter sheet 100, while the oxygen-generating container ribs 210 support the opposite side of the filter sheet 100. The oxygen-generating container coupling frame 220 contacts the filter sheet 100 in the same direction as the oxygen-generating container 200 extending through the filter sheet 100 and provided on one side of the filter sheet 100. A space is formed inside the edge of the oxygen-generating container coupling frame 220, corresponding in shape to the oxygen-generating container ribs 210, thereby allowing the oxygen-generating container coupling frame 220 and the oxygen-generating container ribs 210 to adhere and bond to each other. Therefore, the oxygen-generating container coupling frame 220 and the oxygen-generating container ribs 210 can be coupled to the filter sheet 100 with a portion of the filter sheet 100 having the same horizontal cross-sectional shape interposed therebetween.

[0085] In other words, the oxygen-generating container 200 allows the oxygen-generating container rib 210 to contact the other side of the filter sheet 100, and the oxygen-generating container 200 is disposed on one side of the filter sheet 100, penetrating the region formed by the space of the filter sheet 100. The oxygen-generating container coupling frame 220 can be fixedly coupled to the oxygen-generating container rib 210 on one side of the filter sheet 100, penetrating the oxygen-generating container 200 and sandwiching a portion of the filter sheet 100. Furthermore, the oxygen-generating container rib 210 and the oxygen-generating container coupling frame 220 can be coupled by heat fusion, but this is not a limitation, and can be coupled to each other by physical means such as concave-convex coupling, penetrating a portion of the filter sheet 100 disposed therebetween, as needed.

[0086] When the oxygen-generating container rib 210 is placed on the other side of the filter sheet 100, the oxygen-generating container coupling frame 220 is coupled to the oxygen-generating container rib 210 along the same side as the oxygen-generating container 200 exposed to one side through the space passing through the filter sheet 100, so that the space for storing the oxygen-generating material 10 in the oxygen-generating container 200 is set on one side of the filter sheet 100, and on the other side of the filter sheet 100, the oxygen generated inside the oxygen-generating container 200 can flow only through the opening (opening) portion in the direction of the other side of the filter sheet 100, and on the other side of the filter sheet 100, the portion protruding beyond the horizontal plane of the filter sheet 100 can be reduced. In addition, the oxygen-generating container rib 210 is provided on the other side of the filter sheet 100, and the oxygen-generating container coupling frame 220 coupled thereto is coupled along a side direction of the filter sheet 100 where the exposed portion of the oxygen-generating container 200 is provided, thereby enabling the oxygen-generating container 200 to be more firmly coupled to the filter sheet 100 and maintain the coupled state even when a force is applied to separate the oxygen-generating cover 300.

[0087] In addition, the oxygen-generating container barrier frame 250 can be directly contacted with the other side of the oxygen-generating container rib 210 for combination, and the oxygen-generating container barrier frame 250 and the oxygen-generating container rib 210 are combined by making the oxygen-generating container combining hole 215 formed in the oxygen-generating container rib 210 be combined with the concave portion formed in the oxygen-generating container barrier frame 250 opposite thereto.

[0088] As described above, by sandwiching the filter sheet 100 between the oxygen-generating container ribs 210 and the oxygen-generating container coupling frame 220, the oxygen-generating container 200 is more firmly coupled to the filter sheet 100 while reducing the protrusion on the other side of the filter sheet 100, where oxygen is generated. This allows oxygen to flow into the user's respiratory system through the open portion of the oxygen-generating container 200. Furthermore, the oxygen-generating container barrier frame 250, coupled to the oxygen-generating container ribs 210, prevents the oxygen-generating material 10 from escaping to the outside through the open portion of the oxygen-generating container 200, allowing oxygen to be generated only when necessary from the open portion of the oxygen-generating container barrier frame 250.

[0089] The portion bonded to the filter sheet 100 is divided into the oxygen-generating container rib 210 and the oxygen-generating container bonding frame 220. While securing the oxygen-generating container 200 to the filter sheet 100, the oxygen-generating container barrier frame 250 is separately bonded to the oxygen-generating container rib 210. While ensuring the portion bonded to the oxygen-generating cover 300, the portion bonded to the filter sheet 100 and the portion bonded to the oxygen-generating cover 300 are separated from each other. Furthermore, when manufacturing a life-saving towel, the oxygen-generating container barrier frame 250 is separately bonded to seal the open portion while the oxygen-generating material 10 is placed in the oxygen-generating container 200. The oxygen-generating cover 300 is then bonded to the oxygen-generating container barrier frame 250, making the life-saving towel easier to manufacture. Furthermore, as described above, the oxygen-generating container barrier frames 250 intersect with each other, creating a space inside. This ensures the flow of oxygen while also allowing for stable bonding of the oxygen-generating cover 300.

[0090] in addition, Figure 5 is a perspective view of a life-saving towel according to an embodiment of the present invention, and Figure 6 To express in Figure 5 A cross-sectional view of the cross section of the filter sheet along AA'.

[0091] See Figure 5 and Figure 6 According to one embodiment of the present invention, a filter sheet suitable for a life-saving towel may include a first layer 110 made of a material containing rayon, a second layer 120 formed of a polypropylene material containing activated carbon and disposed on one side of the first layer 110, a third layer 130 formed of a meltblown filter element formed of polypropylene and disposed on one side of the second layer 120, a fourth layer 140 formed of a polypropylene material containing activated carbon and disposed on one side of the third layer 130, and a fifth layer 150 formed of a material containing rayon and disposed on one side of the fourth layer 140. The filter sheet 100, with the first to fifth layers 110, 150 disposed in this order, can block harmful external gases. For example, harmful gases such as carbon dioxide, formaldehyde, sulfur dioxide, nitrogen dioxide, and ammonia can be filtered.

[0092] Furthermore, the filter sheet contains natural extracts included in the first to fifth layers 110 to 150. The natural extracts include one or more selected from the group consisting of propolis extract, green tea extract, tea tree extract, lavender extract, rosemary flower extract, mint extract, peppermint leaf extract, chamomile extract, and water lily extract. The inclusion of these natural extracts can provide a sense of stability to a user using the life-saving towel in an emergency.

[0093] Furthermore, the first layer 110 and the fifth layer 150 weigh between 20g and 30g per 1m2 of width, the second layer 120 and the fourth layer 140 weigh between 35g and 45g per 1m2 of width, and the third layer 130 weighs between 20g and 30g per 1m2 of width. In the case of a filter sheet, a five-layer structure is formed to block harmful gases. While the second layer 120 and the fourth layer 140 contain activated carbon, which weakens breathability, within the weight ranges of the layers, breathability is maintained while blocking harmful gases, ensuring the user's breathing.

[0094] in addition, Figure 7 FIG. 2 is a perspective view of a life-saving towel according to another embodiment of the present invention.

[0095] See Figure 7 , further comprising tapes 410 and 420 bonded to a surface of the filter sheet 100 that is exposed to the oxygen generator housing 200. The tapes 410 and 420 are bonded to the surface of one surface of the filter sheet 100 at both ends, while being separated at their intermediate portions. Specifically, the tapes 410 and 420 comprise a first tape 410 and a second tape 420, which are spaced apart on one surface of the filter sheet 100 with the oxygen generator housing 200 positioned at their central portions. The intermediate portions of the first tape 410 and the second tape 420, separated on the surface of the filter sheet 100, face each other across the oxygen generator housing 200.

[0096] The straps 410 and 420 are coupled to the side of the filter sheet 100 where the oxygen generator container 200 is exposed, so that the user can put his hands into the straps 410 and 420 to hold the oxygen generator container 200, thereby stably holding the life-saving towel and accurately identifying the part where oxygen is generated.

[0097] in addition, Figure 8 The figure is a perspective view of a filter sheet suitable for a life-saving towel according to another embodiment of the present invention.

[0098] See Figure 8 and refer again Figure 5 and 6, further comprising a plurality of cured balls formed of a thermosetting resin composition and spaced between the second layer 120 and the third layer 130 and between the third layer 130 and the fourth layer 140. Figure 5 and Figure 6 As described in [ 15 ], the filter sheet 100 of the present invention can be formed into a five-layer structure comprising a first layer 110 to a fifth layer 150. Cured balls are provided between the second layer 120 and the third layer 130, and between the third layer 130 and the fourth layer 140. The cured balls are cured by thermal compression, thereby further firmly bonding the second layer 120 and the third layer 130, and the third layer 130 and the fourth layer 140, ensuring air permeability. The cured balls exist as a thermosetting resin composition before the filter sheet 100 is finally completed. After application of heat and pressure, they are thermoset to form deformed cured balls. In this deformed state, they firmly bond the second layer 120 and the third layer 130, and the third layer 130 and the fourth layer 140.

[0099] Figure 9 For a rough representation Figure 8 A cross-sectional view of a cross section of a filter sheet, and Figure 10 To roughly represent Figure 9 A cross-sectional view of a cross section of a filter sheet undergoing heat treatment.

[0100] See Figure 9 and Figure 10 , a portion of the plurality of solidified balls is thermally solidified to exist in the form of deformed solidified balls, and the deformed solidified balls are bonded between the second layer and the third layer and between the third layer and the fourth layer. Figure 8 As shown, a plurality of solidified balls are provided and a portion thereof is heat-treated so as to solidify and firmly bond the layers. However, for the convenience of the manufacturing process, all solidified balls are in an unsolidified state because they are not subjected to heat transfer.

[0101] Figure 11 FIG1 is a schematic diagram schematically showing a filter sheet according to another embodiment of the present invention.

[0102] See Figure 11 On the horizontal surface of the life-saving towel, the solidified balls or deformed solidified balls are present at a higher density around the area P where the oxygen generator housing ribs and the oxygen generator housing barrier frame are joined, compared to other areas. This allows for a more secure bond between the oxygen generator housing ribs and the oxygen generator housing barrier frame, which are joined together by heat compression with the filter sheet 100 positioned therebetween.

[0103] Figure 12 FIG2 is a schematic diagram schematically showing a folded state of a life-saving towel according to another embodiment of the present invention. Figure 13 To express Figure 12The oblique view of the unfolded state of the life-saving towel, and Figure 14 To express Figure 12 Schematic diagram of the folded state of the life-saving towel. Figure 15 is a perspective view showing an oxygen production cover according to an embodiment of the present invention, and Figure 16 2 is a perspective view showing a cover opening component according to an embodiment of the present invention.

[0104] See Figures 12 to 16 The oxygen-generating cover 300 includes an oxygen-generating cover protruding surface 310 protruding in one direction to prevent contact with the oxygen-generating container barrier frame 250, and an oxygen-generating cover through-hole 320 formed through the upper and lower sides of the oxygen-generating cover protruding surface 310. The filter sheet 100 also includes an opening component 600 separated from the position where it is combined with the oxygen-generating container 200 and one end of which is combined with the filter sheet 100. The other end of the opening component 600 is connected to the oxygen-generating cover through-hole 320.

[0105] The oxygen generator cover 300 can be bonded to the oxygen generator container barrier frame 250 to seal the oxygen generator material 10 within the oxygen generator cover 300 and the oxygen generator container 200. The oxygen generator cover protrusion 310 protrudes in one direction to prevent contact with the oxygen generator container barrier frame 250. Furthermore, an oxygen generator cover through-hole 320 is formed vertically through the protrusion 310 to allow the opening member 600 to engage. Furthermore, the filter sheet 100 further includes an opening member 600 spaced from the position where it is coupled to the oxygen generator container 200 and having one end coupled to the filter sheet 100. The other end of the opening member 600 is coupled to the oxygen generator cover through-hole 320. This allows the oxygen generator cover 300 to be easily separated through the opening member 600 when the folded filter sheet 100 is opened. In case of a fire or other emergency, or a power outage, it is difficult for the user to find the oxygen generator cover 300 or the user is unable to open the oxygen generator cover 300 due to panic. However, according to the present invention, the other end of the opening member 600 is connected to the through hole 320 of the oxygen generator cover. When the folded filter sheet 100 is opened to the oxygen generator cover, the user can open the oxygen generator cover 300. Figure 13 When used in the manner shown, the oxygen generating cover 300 is separated from the oxygen generating container barrier frame 250 at the same time, so that oxygen can be generated immediately.

[0106] In other words, one end of the opening member 600 penetrates and engages the filter sheet 100, and the other end engages the oxygen generator cover through-hole 320. Therefore, when the folded filter sheet 100 is opened with one end of the opening member 600 fixed to the filter sheet 100, the oxygen generator cover 300 can be peeled off through the oxygen generator cover through-hole 320 engaged at the other end.

[0107] Furthermore, the adhesive strength of the adhesive portion 350 attached to the oxygen-generating cover 300 can range from 25N / 25mm to 35N / 25mm at 50% humidity, and from 25N / 25mm to 35N / 25mm at 85% humidity. Within these ranges, the oxygen-generating cover 300 can achieve IPX8-rated waterproof and moisture-proof performance. Specifically, if the oxygen-generating cover 300 on which the adhesive portion 350 is formed has a width of 25mm and is formed on the front surface of one side of the oxygen-generating cover 300, when bonded to stainless steel and peeled at 180° at 23°C, 50% and 85% humidity, the adhesive strength can range from 25N / 25mm to 35N / 25mm. Alternatively, the adhesive strength can be expressed as peel force.

[0108] Because the oxygen-generating cover 300 has the moisture-proof strength as described above through the adhesive portion 350, it can prevent unnecessary oxygen generation when the life-saving towel is not used for storage. In addition, because the adhesive portion 350 is formed of the material and has the adhesive strength, the internal oxygen-generating substance 10 can be more effectively isolated from the external environment. That is, if the adhesive strength is not achieved, when the life-saving towel is folded for storage, moisture or air may flow into the oxygen-generating container 200, accidentally generating oxygen and increasing the internal volume of the oxygen-generating container 200, which may cause the oxygen-generating cover 300 to collide and peel off. However, within the numerical range, the above situation can be effectively prevented from occurring. In addition, within the range of the adhesive strength, the oxygen-generating cover 300 can be smoothly peeled off when necessary.

[0109] Furthermore, the adhesive portion 350 maintains adhesive strength as described above to prevent the life-saving towel from contacting the outside (or reducing airtightness, allowing external factors to flow in) and generating oxygen when not in use. However, if the adhesive strength is too high, it will become difficult to peel off when the user attempts to use it. Therefore, when the folded filter sheet is opened by the opening member 600 coupled to the oxygen generator cover through-hole 320, the opening member 600 can provide a force sufficient to peel off the oxygen generator cover 300.

[0110] Furthermore, the oxygen-generating cover through-holes 320 can be separated into at least two or more. Since the oxygen-generating cover through-holes 320 are separated into at least two or more, even when the oxygen-generating cover 300, which is bonded within the above-described adhesive strength range, is peeled off with strong force, the oxygen-generating cover through-holes 320 will not be torn or damaged, and can be peeled off from the oxygen-generating container barrier frame 250 while being stably bonded to the opening member 600.

[0111] In addition, to specifically illustrate the cover-opening component 600, the cover-opening component 600 includes: an outer sheet support portion 610, which passes through the filter sheet 100 to support one side of the filter sheet 100, and has an area larger than the through-region; an inner sheet support portion 620, which extends from the outer sheet support portion 610 and passes through the filter sheet 100 to support the other side of the filter sheet 100, and has an area larger than the through-region; and a cover support portion 630, which extends from the inner sheet support portion 620 and passes through the oxygen-generating cover through hole 320 to support one side of the oxygen-generating cover through hole 320, and has an area larger than the through-region.

[0112] In addition, when the filter sheet 100 of the life-saving towel is folded, the outer sheet support portion 610, the inner sheet support portion 620, the cover support portion 630 and the oxygen-generating cover through hole 320 of the cover opening component 600 can be located on the same vertical line.

[0113] The lid opening member 600 includes an outer sheet support portion 610, an inner sheet support portion 620, and a lid support portion 630. The outer sheet support portion 610 extends through the filter sheet 100 to support one side of the filter sheet 100 and has a larger area than the through-hole area, thereby maintaining a fixed position without separating from the filter sheet 100. Furthermore, the inner sheet support portion 620 extends from the outer sheet support portion 610 and extends through the filter sheet 100 to support the other side of the filter sheet 100 and has a larger area than the through-hole area, thereby securing the filter sheet 100 between the outer sheet support portion 610 and the inner sheet support portion 620. Furthermore, the lid support portion 630 extends from the inner sheet support portion 620 and extends through the oxygen generator cover through-hole 320 to support one side of the oxygen generator cover through-hole 320 and has a larger area than the through-hole area, thereby maintaining a fixed position without separating from the oxygen generator cover through-hole 320. Therefore, since the filter sheet 100 fixed at the other end is unfolded by the cover opening member 600 , the oxygen generator cover 300 can be peeled off when the filter sheet 100 is away from the oxygen generator container barrier frame 250 .

[0114] Figure 17 For a rough representation Figure 16 Exploded oblique view of the opening part.

[0115] See Figure 17The inner sheet support portion 620 may further include an inner sheet support portion first connection portion 621 formed at one end, and an inner sheet support portion second connection portion 622 formed at the other end; the cover support portion 630 also includes a cover support portion connection portion 632 formed at the other end and combined with the inner sheet support portion first connection portion 621; the outer sheet support portion 610 also includes an outer sheet support portion connection portion 611 formed at the other end and combined with the inner sheet support portion second connection portion 622. That is, the cover support portion connection portion 632 can be connected to the inner sheet support portion first connection portion 621 formed on the inner sheet support portion 620, and the inner sheet support portion first connection portion 621 can be connected to the outer sheet support portion connection portion 611 formed on the outer sheet support portion 610 to form a mutually combined opening cover component. Through the mutual separation and combination of each component, the opening cover component can be easily assembled in the state of manufacturing the filter sheet 100, and the opening cover component can also be easily combined with the oxygen production cover through hole 320 of the oxygen production cover 300 connected thereto.

[0116] in addition, Figure 18 This is a schematic diagram of an oxygen production device combined with an oxygen production cover according to another embodiment of the present invention, as viewed from above. Figure 19 For viewing from one side Figure 18 Schematic diagram of the oxygen generator combined with the oxygen generator cover. Figure 20 For viewing from another side Figure 18 Schematic diagram of the oxygen production device combined with the oxygen production cover.

[0117] See Figures 18 to 20 , according to another embodiment of the present invention, the cover opening component includes: a cover support portion 630, one end of which passes through the oxygen-generating cover through-hole 320 and has a cross-section larger than the cross-section of the oxygen-generating cover through-hole 320 at the end; an outer sheet support portion 610, the other end of which passes through the filter sheet 100 and supports the filter sheet 100 on one side of the filter sheet 100, includes a cross-section larger than the cross-section of the through-region passing through the filter sheet 100 and is extended from the cover support portion 630; and an inner sheet support portion 620, which is formed in combination between the outer sheet support portion 610 and the oxygen-generating cover through-hole 320 and supports the filter sheet 100 on the other side of the filter sheet 100.

[0118] In addition, as described above, when the filter sheet 100 of the life-saving towel is folded, the outer sheet support portion 610, the inner sheet support portion 620, the cover support portion 630 and the oxygen-generating cover through-hole 630 of the cover opening member 600 can be located on the same vertical line. Figures 19 to 21The cover opening component may be formed with an outer sheet support portion 610 and a cover support portion 630, and an inner sheet support portion 620 is combined at the portion connecting the two components.

[0119] Figure 21 FIG1 is a schematic diagram schematically showing a filter sheet according to another embodiment of the present invention.

[0120] See Figure 21 The solidified balls described in the filter sheet are present at a higher density in the area TN surrounding the area T forming the lid opening member. Furthermore, during assembly of the lid opening member 600, the area of the filter sheet where the lid opening member 600 is located can be heated, thereby more firmly bonding the filter sheet 100 to the lid opening member 600 when the filter sheet 100 is positioned in the middle, thereby preventing the filter sheet 100 from being torn at this location.

[0121] in addition, Figure 22 This is a perspective view showing the ribs of the oxygen production container of the oxygen production device according to another embodiment of the present invention. Figure 23 To show that another embodiment of the present invention is combined with Figure 22 An oblique view of the oxygen production containment barrier frame of the oxygen production device.

[0122] See Figure 22 and 23 , it may also include an oxygen-generating containment body rib concave line 216 formed on the other side of the oxygen-generating containment body rib 210 and formed as a line concave inward, and extending along the edge of the oxygen-generating containment body rib 210 to form a single closed curve, and it may also include an oxygen-generating containment body barrier frame convex line 256 formed on one side of the oxygen-generating containment body barrier frame 250 and formed as a line protruding outward, and forming a single closed curve to correspond to the oxygen-generating containment body rib concave line 216 inserted into the oxygen-generating containment body rib concave line 216.

[0123] The oxygen-generating container rib concave lines 216 and the oxygen-generating container barrier frame convex lines 256 can be bonded together. An additional adhesive can be applied between the oxygen-generating container rib concave lines 216 and the oxygen-generating container barrier frame convex lines 256 to improve bonding and airtightness. The oxygen-generating container rib concave lines 216 and the bonded oxygen-generating container barrier frame convex lines 256 prevent leakage of the oxygen-generating substance contained therein from leaking or creating gaps between the oxygen-generating container barrier frame 250 and the oxygen-generating container ribs 210, thereby reducing airtightness.

The above embodiments are intended to illustrate the present invention only and are not intended to limit the present invention. Those skilled in the art will appreciate that the present invention may be modified, altered, or replaced with equivalents without departing from the spirit and scope of the present invention, and all such modifications, variations, or equivalents are intended to be encompassed by the claims of the present invention.
