It includes an opening member 300 including a coupling protrusion 340 fitted to the filter sheet 100, characterized in that the liquid natural extract is impregnated.

In the filter sheet 100, the first filter sheet 110 on one side and the second filter sheet 120 on the other side may be connected to each other or integrally formed with respect to the left and right directions of the user's face. That is, as shown in FIG. 1, the left and right sides may be manufactured in a form facing each other in a mirror image and may be coupled to each other by fusion, but are not limited thereto, and may be integrally formed. The filter sheet 100 of the present invention is expressed as a combination of two filter sheets 110 and 120 through the drawings, but is not limited thereto, and various forms in which a filter is applied while covering the user's respiratory system may be applied. . Meanwhile, in the present invention, the first filter sheet 110 and the second filter sheet 120 are defined based on the left and right directions, and in fact, in FIG. 1, the right side is the first filter sheet 110, Although the left side is defined as the second filter sheet 120, they may be reversed left and right.

In addition, the filter sheet 100 may be formed by combining a single layer or multiple layers of a filter layer composed of, but not limited to, a melt blown filter layer, a filter layer composed of a polypropylene material and a material containing activated carbon, and a filter layer composed of fibers. It is not particularly limited, and various filters applied to a breathing mask widely known in the art or a gas mask for blocking toxic gas may be used.

The earring part 10 is coupled to both ends of the first filter sheet 110 and the second filter sheet 120 and hangs on the user's ears to fix the filter sheet 100 on the user's face. The earring portion 10 may be formed of elastic cloth or fiber material, but is not particularly limited thereto, and may exist in various shapes and materials.

The oxygen generator 200 is coupled to the first filter sheet 110 and is sealed on the outer surface of the first filter sheet 110 while accommodating the oxygen generating composition in the inner space, and the first filter sheet 110 The receptor 210 opened on the inner surface of the first filter sheet 110 through a part of the receptor 210, the receptor rib formed on the edge of the open portion of the receptor 210, and the first filter sheet 110 It includes a receiver fixing part 230 coupled to the receiver rib on the outer surface of the first filter sheet 110 with a part interposed therebetween. That is, the oxygen generator 200 is for accommodating an oxygen-generating composition that generates oxygen by contacting the user's breathing air or external air. When the oxygen-generating composition is not used, the open part of the receiver is the cover It is sealed by (400). On the other hand, in order to accommodate the oxygen generating composition therein, the receptor 210 may have a cross-sectional shape like a U-shape.

Since the receptor 210 penetrates and is coupled through a part of the first filter sheet 110, only the sealed portion is exposed on the outer surface of the first filter sheet 110, and the oxygen generating composition present inside is only directed toward the user. can be made open. As a result, when using the lifesaving mask, oxygen is generated only on the inner side, which is in contact with the user's respiratory tract, so that it proceeds to the user's respiratory tract. The receiver rib is in contact with the first filter sheet 110 on the inner side of the first filter sheet 110, and the outer side of the first filter sheet 110 and the receiver fixing part 230 having a shape corresponding to the receiver rib and each other. They can be joined by fusion. As a result, a part of the first filter sheet 110 is held between the receptor rib and the receptor fixing part 230, and eventually the receptor 210 can be fixed to the first filter sheet 110.

On the other hand, the oxygen generator is coupled to one surface of the receiver rib from the inside of the first filter sheet 110, and includes a plurality of perforated ventilation areas, and the oxygen generating composition accommodated in the receiver 210 flows out to the outside. It may include a receptor ventilation unit 220 to prevent it from becoming. As a result, it is possible to prevent the oxygen generating composition from leaking out to the outside while allowing ventilation so that the user can breathe the generated oxygen. Likewise, air or outside air generated from the user's breath can be transferred to the oxygen generating composition (when in use). On the other hand, the container ventilating part 220 may be sealed by the cover part 400 so that the oxygen generating composition does not come into contact with the outside when stored in a packaged state without using a lifesaving mask.

The cover part 400 is bonded to one surface of the oxygen generator 200 on the inner surface of the first filter sheet 110 to seal the oxygen generating composition therein, but includes a through hole formed by partially penetrating the cover part 400 . As already described, the cover part 400 is for sealing the oxygen generating composition present inside the oxygen generator 200 from the outside when the lifesaving mask is not used together with the receptor 210, and the through hole is open It is fitted and coupled by the coupling protrusion 340 of the member 300, so that the cover part 400 can be separated from the oxygen generator 200 and peeled off according to the movement of the second filter sheet 120.

The opening member 300 has one end extending from the outer plate 310 disposed on the outer surface of the second filter sheet 120 and the outer plate 310 to protrude toward the cover part 400, A coupling protrusion 340 penetrates the second filter sheet 120 and is fitted into the through hole of the cover part 400 . That is, the outer plate 310 of the opening member 300 is formed in a flat plate shape and is disposed while supporting the outer surface of the second filter sheet 120, and the coupling protrusion 340 extends from the outer plate 310 and protrudes. passes through the second filter sheet 120 and proceeds to the inner surface of the second filter sheet 120 and is again coupled to the cover part 400 disposed on the inner side, so that the inside and outside of the second filter sheet 120 is configured. It can be firmly fixed while existing in connection. Therefore, even when the second filter sheet 120 is moved toward the outer surface (so that the mask is unfolded in a folded state) and force is applied to the cover part 400, the outer plate 310 can stand firmly without being separated, and further The cover part 400 can be peeled off by the coupling protrusion 340 connected thereto. Therefore, when the user is not using the lifesaving mask, the filter sheets 110 and 120 of the mask exist in a folded state so that the first filter sheet 110 and the second filter sheet 120 face each other and overlap each other. While present, when the first filter sheet 110 and the second filter sheet 120 are unfolded to use the mask, the cover part 400 is opened by the configurations of the opening member 300 coupled to the second filter sheet 120. can be separated. Accordingly, the cover part 400 is naturally separated when the earring part 10 of the first filter sheet 110 and the second filter sheet 120 are spread away from each other without the need to separate the cover part 400 separately. It can be used immediately in an emergency situation. In other words, the cover part 400 opens the oxygen generator 200 by the opening member 300 when the first filter sheet 110 and the second filter sheet 120 of the filter sheet 100 are unfolded. It can be characterized as being separated from.

Meanwhile, the filter sheet 100 is impregnated with a liquid natural extract. Accordingly, in the event of a fire or the like, it is possible to respond more calmly in an emergency situation by providing a sense of security to the user while more effectively blocking harmful substances introduced from the outside. On the other hand, the natural extract includes at least one selected from the group consisting of propolis extract, green tea extract, tea tree extract, lavender extract, rosemary flower extract, peppermint extract, conmint leaf extract, matricaria extract, and water lily flower extract. It may be, but is not particularly limited thereto. On the other hand, the propolis extract, green tea extract, tea tree extract, lavender extract, peppermint extract, cornmint leaf extract, and matricaria extract can give a soothing effect to the sensitive skin of the user, and soothe the skin heated by heat. It can give a sedative effect. In addition, the rosemary flower extract can impart sterilization and disinfection effects to the skin, and the water lily flower extract can alleviate skin irritation.

On the other hand, the cover portion 400 is bonded to the receptor ventilation portion 220 while covering all of the receptor ventilation portion 220 to seal the oxygen generating composition inside the oxygen generator 200 (after all, the oxygen generator It is sealed by the coupling between the components of the cover and the components of the cover, or it is expressed as being sealed inside the oxygen generator for convenience of explanation.), the through-hole formed protrusion without contacting the receptor vent 220. area, and the coupling protrusion 340 of the opening member 300 may be coupled to the through hole formed in the protruding area of the cover part 400 . That is, the cover part 400 is formed to cover and cover the entire area of the receiver vent 220 or the receiver rib while being bonded to the receiver vent 220 to perform sealing, but is formed to be larger than that of the receiver ( 200) may form a protruding area not in contact with the structure. By forming a through hole in the protruding area and fitting and coupling the coupling protrusion 340 of the opening member 300 to the through hole formed in the protruding area, the cover part 400 can be easily separated with less force. .

For ease of storage and storage stability, the cover part 400 may be firmly attached to the configuration of the oxygen generator 200. In this way, the cover part 400 is formed larger to secure the protruding area and protruding area By forming a through hole and connecting it to the connecting member (through the coupling protrusion 340), it is possible to secure a margin for applying force to separate the bonded portion of the cover part 400, and immediately when the user uses , and can easily separate the cover part 400.

On the other hand, the through hole of the cover part 400 is formed with respect to the filter sheet 100 so that the cover part 400 can be more easily separated while the filter sheets 110 and 120 are unfolded. ) and may be formed in an adjacent position. That is, the meaning that the through hole of the cover part 400 is formed at a position adjacent to the earring part 10 means that a configuration such as a coupling protrusion 340 coupled therewith or a connecting member associated therewith is located adjacent to the earring part 10. This means that the first filter sheet 110 and the second filter sheet 120 are subjected to force at a part far from the central part where the first filter sheet 110 and the second filter sheet 120 are coupled to each other, so that the cover part 400 is more easily separated and torn in other components. damage can be prevented from occurring.

More specifically, as shown in FIG. 4, one end to which the first filter sheet 110 and the second filter sheet 120 are connected and the other end to which the earring part 10 is formed are formed on the surface of the filter sheet 100.

2KO ₂ + 2H ₂ O → O ₂ + 2KOH + H ₂ O ₂

On the other hand, when the weight ratio of the potassium peroxide to the calcium hydroxide satisfies the range of 8:2 to 4:6, oxygen can be generated more quickly and more oxygen can be generated compared to the introduced carbon dioxide. Preferably, for example, the potassium peroxide to the calcium hydroxide ranges in weight ratio from 8:2 to 5:5, from 7:3 to 5:5, from 7.5:2.5 to 5.5:4.5, or from 7:2 to 5:4.5. It may range from 3 to 6:4. On the other hand, when the content of potassium peroxide is too large, for example, when the potassium peroxide to calcium hydroxide exceeds a ratio of 8:2 in weight ratio, moisture generated in the primary reaction with calcium hydroxide becomes a reaction paste with the powder compound, resulting in a reaction Delays may occur.

On the other hand, the oxygen generating composition may be characterized in that it further comprises manganese dioxide (MnO2). By including the manganese dioxide, more oxygen can be generated. For example, when H ₂ O ₂ is generated through the above reaction formula (2), oxygen and water are additionally generated through a reaction such as the following reaction formula (3), and the additionally produced water is again generated through the above reaction formula (2). ), it is possible to generate more oxygen.

Reaction equation (3)

For example, the manganese dioxide (MnO ₂ ) may be in the range of 5 to 20 parts by weight based on 100 parts by weight of the potassium peroxide and the calcium hydroxide. Oxygen can be generated more quickly while securing a sufficient oxygen generation amount within the above range.

On the other hand, the oxygen generating composition may be characterized in that it further comprises potassium nitrate (KNO ₃ ) or potassium chloride (KCl). In the process of the oxygen generating composition reacting with carbon dioxide and eventually generating oxygen by the water produced thereby, a rapid exothermic reaction may proceed, and eventually the oxygen generating composition may rise to a high temperature due to the high reaction temperature. there is. In this case, there may be a problem that the user's skin is damaged or the respiratory system is damaged by high temperature. By including potassium nitrate (KNO ₃ ) or potassium chloride (KCl) as described above, the heat generated by the reaction can be absorbed. As a result, the temperature of the oxygen-generating composition is prevented from being increased in the process of reacting and generating oxygen, so that the user can use the oxygen-generating composition more safely.

For example, the potassium nitrate or the potassium chloride may be characterized in that the range of 100 to 240 parts by weight based on 100 parts by weight of the potassium peroxide and the calcium hydroxide. It is possible to effectively control the exothermic reaction while having a sufficient amount of oxygen generation in the above range.

In addition, the potassium nitrate or the potassium chloride may be characterized in that it is included in the range of 3 to 5 times in weight ratio compared to the potassium peroxide, for example, the potassium nitrate or the potassium chloride is 3.5 in a weight ratio to the potassium peroxide It may be characterized in that it is included in the range of times to 4.5 times. In the above range, it is possible to very effectively prevent a temperature rise due to an exothermic reaction while the oxygen generating composition reacts, and also to prevent a reduction in the amount of oxygen generation. That is, when the potassium nitrate or potassium chloride is less than 3 times, the temperature increase control effect may be insignificant, and when it exceeds 5 times, a lot of paste phenomenon may occur and the amount of oxygen generation may be reduced. A positive amount of oxygen can be generated.

On the other hand, the oxygen generating composition may be characterized in that it further comprises sodium bicarbonate (NaHCO ₃ ). The sodium bicarbonate allows the oxygen-generating composition to generate excess oxygen during the initial reaction so that excess oxygen can be generated immediately in an emergency situation, especially in a disaster situation such as a fire in which toxic gases spread in large amounts more quickly of oxygen can be generated. For example, the materials produced by Reaction Formula (1) and Reaction Formula (2) may be basic, and by adding sodium bicarbonate, the corresponding basicity is neutralized by an acid-base reaction to obtain the reaction formula (1) and It can play a role of accelerating the reaction so that the reaction of Reaction Formula (2) proceeds actively. As a result, by removing the KOH compound produced by reaction formula (2) by acid-base reaction with sodium bicarbonate, it is possible to make the reaction proceed more toward the product and rapidly generate more oxygen.

The sodium bicarbonate may be characterized in that it is included in the range of 20 to 40 parts by weight based on 100 parts by weight of the potassium peroxide and the calcium hydroxide. Oxygen can be generated more quickly while securing a sufficient oxygen generation amount within the above range.

Meanwhile, the oxygen generating composition may further include silica (SiO ₂ ). During the process of reacting the potassium peroxide and the calcium hydroxide to generate oxygen, they can be agglomerated by agglomeration, which can reduce the amount of oxygen generation. can make it happen. The silica may be included in the range of 10 parts by weight to 40 parts by weight or 10 parts by weight to 30 parts by weight based on 100 parts by weight of the potassium peroxide and the calcium hydroxide. It is possible to prevent agglomeration while securing a sufficient amount of oxygen generation within the above range.

It can be characterized by doing.

Hereinafter, the oxygen generating composition applied to the lifesaving mask of the present invention will be described in more detail through specific experimental data.

Experimental Example 1 (Oxygen generation test)

5g of potassium peroxide (KO ₂ ) and calcium hydroxide (Ca(OH) ₂ ) were mixed at a weight ratio of 1:1, placed in a chamber, and the concentration of carbon dioxide (CO ₂ ) in the reactor was measured over time to verify the chemical reaction. A test was conducted, and the results are shown in FIG. 11 below. In the experiment, an oxygen concentration meter, a carbon dioxide concentration meter, and a sample were sequentially placed in a chamber equipped with a stirring fan (size (inner diameter): 350 mm x 298 mm x 360 mm), and oxygen and carbon dioxide were sampled in the center of the chamber. The oxygen concentration meter was WINTACT's WT8811 model, and the carbon dioxide concentration meter was AHLBORN's 2590-2A model. Thereafter, carbon dioxide was injected into the chamber at a concentration of 6,000 to 8,000 umol/mol (ppm), and the concentrations of oxygen and carbon dioxide were measured at 10-second intervals for 15 minutes from the time the carbon dioxide gas was injected, and repeated three times in total.

As shown in FIG. 11, when potassium dioxide (KO ₂ ) and calcium hydroxide (Ca(OH) ₂ ) were mixed, it was confirmed that the concentration of carbon dioxide decreased and the concentration of oxygen increased over time. It can be seen that almost all of the carbon dioxide is converted to oxygen after 10 hours at the initial concentration of 0.2%. It was confirmed that the concentration of oxygen increased from 12.5% at the beginning to 14% after 10 hours due to the conversion of carbon dioxide by a chemical reaction. As can be seen from the results of Experimental Example 1, it was confirmed that carbon dioxide was converted into oxygen through a chemical reaction when potassium dioxide (KO ₂ ) and calcium hydroxide (Ca(OH) ₂ ) of the present invention were mixed.

Experimental Example 2 (optimal oxygen generation mixing ratio)

While changing the compounding ratio of potassium peroxide (KO ₂ ) and calcium hydroxide (Ca(OH) ₂ ) as shown in Table 1 below, the total weight based on each compounding ratio was configured as 5 g, and the oxygen generation amount for each weight ratio was measured. By measuring the level of carbon dioxide, it was found that the amount of oxygen generated increased as the amount of carbon dioxide decreased, and the results of the amount of decrease of the corresponding carbon dioxide over time are shown in FIG. 12 below. On the other hand, the measurement of carbon dioxide was measured at room temperature using a test equipment using a water displacement method, and the amount of oxygen generation by composition ratio was predicted through the measurement of carbon dioxide.

EN ₂ Ca(OH) ₂ Formula 1 7 3 Formula 2 6 4 Mixing Ratio 3 5 5 Formula 4 4 6 Formula 5 3 7

As shown in the results of FIG. 12, the ratio of potassium peroxide (KO ₂ ) and calcium hydroxide (Ca(OH) ₂ ) is 7:3 (mixing ratio 1) and 6:4 (mixing ratio 2), the reduction of carbon dioxide It was confirmed that the most rapid progress occurred and the greatest decrease. In addition, the ratio of potassium peroxide (KO ₂ ) and calcium hydroxide (Ca(OH) ₂ ) is 5:5 (mixing ratio 3) and 4:6 (mixing ratio 4) at a ratio of 3:7 (mixing ratio 5) It was confirmed that a large amount of oxygen was generated due to a rapid decrease in carbon dioxide compared to the carbon dioxide. Through this, it was confirmed that a large amount of oxygen was quickly generated while carbon dioxide rapidly decreased within the range of the content ratio of the compounding ratio of the present invention. Therefore, it was confirmed that oxygen was generated very efficiently in the range of 8:2 to 4:6 in weight ratio of the potassium peroxide to the calcium hydroxide, preferably in the range of 8:2 to 5:5, or 7:3 to 5:5, or may be in the range of 7.5:2.5 to 5.5:4.5, and most preferably the range of 7:3 to 6:4 can produce an excellent oxygen generating effect. On the other hand, when the content of the potassium peroxide is too large and exceeds the ratio of 8:2 (for example, when the ratio is 9:1), the moisture generated in the first reaction with calcium hydroxide forms a reaction paste with the powder compound. It is preferable that the range of 8:2 to 4:6 is caused because the reaction is delayed.

Experimental Example 3 (Oxygen generation trend test by manganese dioxide and silica)

In a state in which 3.5 g of potassium peroxide and 2.1 g of calcium hydroxide were mixed, the amount of oxygen generation was measured by mixing the contents of manganese dioxide (MnO ₂ ) and silica (SiO ₂ ) according to the mixing ratio shown in Table 2 below, and the results are shown in FIG. 13 was

EN ₂ Ca(OH) ₂ MnO ₂ Silica (SiO ₂ ) Formula 6 3.5g 2.1g - - Formula 7 3.5g 2.1g 1g - Formula 8 3.5g 2.1g 1.5g - Formula 9 3.5g 2.1g 1g 0.75g Formula 10 3.5g 2.1g 1g 1.5g Formula 11 3.5g 2.1g 0.5g 1.5g

As shown in FIG. 13, it was confirmed that when manganese dioxide was added, more oxygen was generated compared to the case where it was not. That is, it was confirmed that a larger amount of oxygen was generated in the case of the compounding ratios 7 and 8 compared to the case where the manganese dioxide of the compounding ratio 6 was not added. In addition, it was confirmed that a greater amount of oxygen was generated in the case of blending ratios 9 to 11 in which a small amount of silica was added compared to the blending ratios 7 and 8 in which manganese dioxide was added and silica was not spread.

Experimental Example 4 (reaction temperature test)

A mixture of 3.5 g of potassium peroxide and 2.1 g of calcium hydroxide was reacted with water to measure the temperature over time, and the results are shown in FIG. 14 below. As shown in FIG. 14, when potassium peroxide and calcium hydroxide react with water to generate oxygen in a mixed state, it was confirmed that a high temperature appears due to a rapid exothermic reaction during the reaction.

Experimental Example 5 (exothermic reaction control test)

In a state where 2 g of calcium hydroxide is mixed with 3 g of potassium peroxide (KO ₂ ) as an oxygen generating composition The temperature generated over time was measured while changing the content of potassium nitrate (KNO ₃ ) to 3.0 g, 6.0 g, 9.0 g, and 12.0 g, respectively, and the results are shown in FIG. 15.

As shown in FIG. 15, when potassium peroxide is added, the initial calorific value can be reduced compared to FIG. 14 when potassium peroxide is not added, and the overall temperature can be lowered over time. In addition, when 12.0 g of potassium nitrate was mixed with 3 g of potassium peroxide, it was confirmed that the reaction heat was absorbed compared to other contents, the exothermic reaction was reduced, and the temperature was lowered, so that the oxygen generating composition could be used more stably. If the potassium nitrate is excessively increased by more than 5 times compared to the potassium peroxide, the exothermic reaction is suppressed, but a paste phenomenon may occur, and the amount of oxygen generation, which is the main purpose of the oxygen generating composition, may be reduced. Therefore, preferably, the potassium chloride may be included in the range of 3 to 5 times in weight ratio compared to the potassium peroxide, for example, the potassium nitrate or the potassium chloride is in the range of 3.5 to 4.5 times in weight ratio to the potassium peroxide It can be characterized by being included as. It is possible to suppress the exothermic reaction within the above range to lower the reaction temperature so that a sufficient amount of oxygen can be generated while stably using the oxygen generating composition.

Experimental Example 6 (reaction rate test by sodium bicarbonate)

When 3.5 g of potassium peroxide and 2.1 g of calcium hydroxide were mixed, when sodium bicarbonate (NaHCO ₃ ) was mixed and when not mixed, the amount of oxygen generation was measured by mixing with water, and the result of the amount of oxygen generation over time It is shown in Figure 16 below. As shown in FIG. 16, it was confirmed that oxygen was rapidly generated when sodium bicarbonate was added compared to when sodium bicarbonate was not added. This is because the KOH produced as a result of the chemical reaction of potassium peroxide and calcium hydroxide with carbon dioxide (CO ₂ ) and moisture (H ₂ O) is removed through an acid-base reaction with sodium bicarbonate (NaHCO ₃ ), thereby changing the direction of the reaction. It is understood that this is because it moves more toward the product. Therefore, it was confirmed that by adding sodium bicarbonate, the reaction proceeds more rapidly, so that oxygen can be immediately generated in an emergency.
