Description

Technical Field

[0001] The invention relates to an oxygen generating composition capable of generating oxygen and adjusting the amount of oxygen generated and a device containing the same. Background Art

[0002] Recently, the occurrence and rescue of various man-made disasters are increasing, but in fact, compared with the demand, there is a lack of systematic response. This phenomenon is caused by social anxiety and imperfect disaster factors. Due to the failure to respond appropriately, it often develops into major accidents and casualties. In disaster and emergency rescue situations, the most likely phenomenon is the symptom of dyspnea caused by poor oxygen supply. Especially at the scene of a fire, the fierce burning phenomenon forms an updraft, which makes it impossible to supply oxygen to the disaster site, which poses a major threat to the trapped people at the scene or their emergency rescuers. At the same time, when the emergency patient reaches a state of shock due to fainting or various diseases, autonomic nerve paralysis will cause dyspnea, and enough oxygen cannot be delivered to the brain, resulting in impaired brain function or brain death. Therefore, in order to prevent disasters or prevent secondary disaster factors for workshop workers, countries or production sites are stepping up the pace to develop various gas masks that meet the actual conditions on the site.

[0003] So far, there are many types of gas masks that can be used on site. One of them is a gas mask that can protect the face, ensure vision, and filter the polluted external air with a filter so that the user can breathe in fresh air. This form is limited by the material of the filter, and the form of the filtered substance is limited. In most cases, the purpose is to remove dust, and the gas mask needs to be worn on the entire face, which will bring many inconveniences. In addition, the filter is too expensive, and there is a problem of excessive funds required.

[0004] Secondly, there are masks equipped with compressed air tanks. This type of mask connects the face to the air reservoir and breathes with prepared air, thereby ensuring the safety of the workers. In addition, the entire face is covered with glass to ensure vision. This method has a low application rate due to the large weight and volume of the product. In other words, due to the excessive weight, the user's dynamic range and diversity are reduced. In addition, due to the connection hose between the compressed air tank and the mask, the work efficiency is reduced and it may be difficult to ensure the field of vision. In addition, due to problems such as damage to various connection parts between the tank and the mask during work, there is a disadvantage of reduced work concentration.

[0005] In view of this, it is actually necessary to study an oxygen generating composition that is easy to use, can generate oxygen immediately, and can be used continuously and safely. Summary of the invention

[0039] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the embodiments of the present invention may be modified into a variety of different forms, and the scope of the present invention is not limited to the embodiments described below. Moreover, the embodiments of the present invention are used to more fully explain the present invention to those skilled in the art.

[0040] The oxygen generating composition according to an embodiment of the present invention comprises potassium peroxide (KO2) and calcium hydroxide (Ca(OH)2), wherein the weight ratio of the potassium peroxide to the calcium hydroxide is in the range of 8:2 to 5:5. Carbon dioxide transmitted by the respiratory organs of the user or carbon dioxide transmitted by the surroundings can trigger a reaction to generate water (H2O) through the calcium hydroxide, and the generated water causes the potassium peroxide to react, thereby promoting the generation of oxygen (O2).

[0041] For example, the oxygen generating composition of the present invention promotes the generation of oxygen by sequentially reacting, such as the following reaction formulas (1) and (2). That is, as shown in the following reaction formula (1), calcium hydroxide (Ca(OH)2) can generate calcium carbonate (CaCO3) and water (H2O) through carbon dioxide (CO2) generated in the mouth or nose of the user or flowing in from the surrounding area, and the water (H2O) generated according to the reaction formula (1) reacts with potassium peroxide (KO2) through the reaction of the following reaction formula (2) to generate oxygen (O2), potassium hydroxide (KOH) and hydrogen peroxide (H2O2) products, and finally generate oxygen.

[0042] Reaction (1)

[0043] Ca(OH)2+CO2→CaCO3+H2O

[0044] Reaction (2)

[0045] 2KO2+2H2O→O2+2KOH+H2O2

[0046] In addition, the weight ratio between the potassium peroxide and the calcium hydroxide satisfies the range of 8:2 to 4:6, oxygen can be generated more quickly, and more oxygen can be generated relative to the inflowing carbon dioxide. Preferably, the weight ratio of the potassium peroxide to the calcium hydroxide can be in the range of 8:2 to 5:5, or in the range of 7:3 to 5:5, or in the range of 7.5:2.5 to 5.5:4.5, or in the range of 7:3 to 6:4. In addition, when the content of potassium peroxide is too high, for example, when the weight ratio of the potassium peroxide to the calcium hydroxide exceeds the ratio of 8:2, the calcium hydroxide and the water generated in the primary reaction become powdery compounds and gelatinization reaction, and there is a problem of delayed reaction.

[0047] In addition, the oxygen generating composition may further include manganese dioxide (MnO2). The manganese dioxide is included to generate more oxygen. For example, when H2O2 is generated by the reaction formula (2), oxygen and water are further generated by a reaction as shown in the following reaction formula (3), and the further generated water is again passed through the process of the reaction formula (2) to generate more oxygen.

[0048] Reaction (3)

[0049]

[0050] For example, the manganese dioxide (MnO2) is in the range of 5 to 20 parts by weight relative to 100 parts by weight of the potassium peroxide and the calcium hydroxide. Within the range, sufficient oxygen generation can be ensured and oxygen can be generated more quickly.

[0051] In addition, the oxygen generating composition may further include potassium nitrate (KNO3) or potassium chloride (KCl). The reaction is that the oxygen generating composition reacts with carbon dioxide, and finally, oxygen is generated through the water generated thereby. During this process, a rapid exothermic reaction may occur, and as a result, the oxygen generating composition may heat up due to the high reaction temperature. At this time, the user may suffer from skin damage or respiratory damage due to high temperature. The inclusion of potassium nitrate (KNO3) or potassium chloride (KCl) can absorb the heat generated by the reaction, thereby causing the oxygen generating substance to react, thereby preventing the temperature from rising during the process of generating oxygen, and allowing the user to use the oxygen generating substance more safely.

[0052] For example, the potassium nitrate or potassium chloride is in the range of 100 to 240 parts by weight relative to 100 parts by weight of the potassium peroxide and the calcium hydroxide. Within the above range, sufficient oxygen generation can be ensured and thermal reaction can be effectively controlled.

[0053] Furthermore, the potassium nitrate or the potassium chloride is contained in a weight ratio of 3 to 5 times relative to the potassium peroxide. For example, the potassium nitrate or the potassium chloride is contained in a weight ratio of 3.5 to 4.5 times relative to the potassium peroxide. Within the above range, it is possible to extremely effectively prevent the oxygen generating substance from reacting while the temperature increases due to the exothermic reaction and the amount of oxygen generated decreases. That is, when the potassium nitrate or the potassium chloride is less than 3 times, the temperature increase control effect is very small, and when it exceeds 5 times, gelatinization occurs more frequently, which leads to a decrease in the amount of oxygen generated. Therefore, within the above range, more oxygen can be generated while the temperature is effectively controlled.

[0054] In addition, the oxygen generating composition may further include sodium bicarbonate (NaHCO3). The sodium bicarbonate generates excess oxygen when the oxygen generating composition undergoes an initial reaction, and generates excess oxygen immediately in critical situations, and in particular, generates a large amount of oxygen more rapidly in disaster situations, such as when toxic gases diffuse. For example, the substance generated by the reaction formula (1) and the reaction formula (2) may be alkaline, and as the sodium bicarbonate is added, the alkalinity is neutralized by an acid-base reaction, which can promote the reaction, so that the reaction of the reaction formula (1) and the reaction formula (2) becomes active. As a result, the sodium bicarbonate removes the KOH compound generated by the reaction formula (2) through the acid-base reaction, thereby causing the reaction to proceed more toward the product direction, causing more oxygen to be generated more rapidly.

[0055] The sodium bicarbonate is contained in an amount of 20 to 40 parts by weight relative to 100 parts by weight of the potassium peroxide and the calcium hydroxide. Within the above range, a sufficient amount of oxygen generation can be ensured and oxygen can be generated more rapidly.

[0056] In addition, the oxygen generating composition may further include silicon dioxide (SiO2). In the process of the potassium peroxide and the calcium hydroxide reacting to generate oxygen, the agglomeration phenomenon may cause a reduction in the amount of oxygen generated. Further including the silicon dioxide can prevent such agglomeration phenomenon and achieve a sufficient amount of oxygen generated. The silicon dioxide is included in the range of 10 to 40 parts by weight or in the range of 10 to 30 parts by weight relative to 100 parts by weight of the potassium peroxide and the calcium hydroxide. In the above range, sufficient oxygen generation can be ensured and agglomeration can be prevented.

[0057] In addition, the oxygen generating composition of the present invention further comprises at least one component selected from the group consisting of frankincense, ylang-ylang, cinnamon, orange blossom, bergamot, lemongrass, sweet orange, lavender, rose, rosemary, sage, Roman chamomile and peppermint essential oils. The further inclusion of the above components can give the user a sense of stability together with the oxygen generated by the oxygen generating material.

[0058] More specifically, the frankincense essential oil is made from the resin of trees of the genus Boswellia, the main common components of which are a-pinene, limonene, a-thujene, myrcene, sabinene, and para-cymene, which have anxiety-relieving properties and effects on sleep and wakefulness.

[0059] In addition, the ylang-ylang essential oil is distilled and extracted from the flowers and stems of the ylang-ylang tree, and is composed of 150 molecules including monoterpenes, sesquiterpenes, aliphatic compounds, phenylpropanoids, and nitrogen-containing compounds. Benzylbenzoate, linalool, and benzyl alcohol are main components, which help relieve anxiety and have a calming effect.

[0060] In addition, the cinnamon essential oil is extracted from the brown bark of the Cinnamomum Verum tree, and most of its components are phenolic compounds. The main active compounds of sesquiterpene and monoterpene hydrocarbons can control adrenaline secretion, help treat depression, and give users a sense of stability.

[0061] In addition, the orange blossom essential oil is obtained by distilling the flowers of the sour orange tree, and is rich in limonene, b-myrcene, and b-pinene, which can significantly reduce the degree of stress and has an excellent effect in relieving menopausal symptoms.

[0062] In addition, the bergamot essential oil is extracted from the exocarp and mesocarp of bergamot fruit, and mainly consists of limonene, linalyl acetate, and linalool, which can minimize the symptoms of anxiety and mild mood disorders caused by stress. Bergamot essential oil intervenes in the relief of anxiety and has antidepressant properties, giving users a sense of stability.

[0063] In addition, the lemongrass essential oil is extracted from the leaves of lemongrass by hydrogenation distillation, and is mostly composed of citral such as neral and geranial. The compounds b-myrcene, limonene, citronellol, geraniol, 1,8-cineole, nerole, a-terpineol, burneol, eugenol, geranyl acetate, and elemicin contained in the component show a significant reduction effect on anxiety and subjective stress.

[0064] In addition, the sweet orange essential oil is a highly volatile compound d-limonene, b-myrcene, a-pinene, sabinene, linalool, geranial and neral, which is extracted from sweet orange bark through cold pressing. The sweet orange essential oil can significantly reduce the concentration of oxygenated hemoglobin in the right prefrontal cortex, increase comfort and strongly relieve anxiety.

[0065] In addition, the lavender essential oil is extracted from lavender flowers by steam distillation, and the main compounds are linalyl acetate, linalool, lavandul acetate, myrcene, terpinen-4-ol, terpineol, cis-linalool oxide, trans-linalool oxide, and ocimene. Lavender essential oil can be used to treat mild stress and anxiety, has a very beneficial effect on sleep quality and duration, and can effectively relieve the symptoms of anxiety.

[0066] In addition, the rose essential oil can be obtained by distilling Rosa Damascena flowers. Most of the components of rose essential oil are monoterpene alcohols. In addition, 2-phenylethyl alcohol, citronellol, geraniol, methyleugenol and eugenol can significantly improve sleep quality and intervene in anxiety relief by increasing blood oxygen saturation and reducing spontaneous wakefulness.

[0067] Rosemary essential oil is obtained by distilling the above-ground part, and is composed of 16 compounds, namely, cineole, camphor, a-pinene, camphene, and a-terpineol. a-Pinene has the property of alleviating anxiety and is effective in improving memory and mood.

[0068] Furthermore, the sage essential oil is obtained by distilling the entire aerial part of sage, and the linalool, a-terpineol, geraniol, geraniol acetate and myrcene acetate compounds contained therein interfere with the effects of antidepressants and show significant anxiety-relieving properties.

[0069] In addition, the Roman chamomile essential oil is an essential oil obtained by distilling the flowers of Roman chamomile, and contains isobutyl angelate, isoamyl angelate, and 2-methylbutyl isobutylrate as component compounds, which is effective as a psychological stimulant and has anxiety-relieving and calming effects.

[0070] Furthermore, the peppermint essential oil is obtained by steam distilling the leaves of peppermint. Among the composition consisting of more than 26 compounds, most of them are menthol and isomenthone, which can improve concentration and memory.

[0071] In addition, the oxygen generating composition contains the peppermint essential oil, which is contained in the range of 5 to 10 weight % relative to the total content of the oxygen generating composition. The lavender, rosemary, rose and sweet orange are contained in the range of 0.1 to 1.0 weight %.

[0072] Hereinafter, the oxygen generating composition of the present invention is further described in detail through specific test data.

[0073] Test Example 1 (Testing whether oxygen occurs)

[0074] 5 g of potassium peroxide (KO2) and calcium hydroxide (Ca(OH)2) were mixed in a weight ratio of 1:1 and allowed to stand. To test whether a chemical reaction occurred, a test was performed to detect the concentration of carbon dioxide (CO2) in the reactor at different times, and the results are shown in Figure 1In the test, an oxygen concentration detector, a carbon dioxide concentration detector, and a sample were placed in the chamber (size (inner diameter): 350mm x 298mm x 360mm) equipped with a stirring fan, and oxygen and carbon dioxide were sampled in the center of the chamber. The oxygen concentration detector used was the WT8811 model of WINTACT, and the carbon dioxide concentration detector used was the 2590-2A model of AHLBORN. Then, carbon dioxide was injected into the chamber at a concentration of 6,000 to 8,000umol / mol (ppm). Since the injection of carbon dioxide gas, the concentrations of oxygen and carbon dioxide were detected every 10 seconds for a total of 15 minutes, and repeated 3 times.

[0075] like Figure 1 As shown, when potassium dioxide (KO2) and calcium hydroxide (Ca(OH)2) are mixed, it is confirmed that the concentration of carbon dioxide decreases and the concentration of oxygen increases over time. The initial concentration of carbon dioxide is 0.2%, and after 10 hours, almost all of the carbon dioxide is converted into oxygen. It is confirmed that the initial concentration of oxygen is 12.5%, and the conversion reaction of carbon dioxide is carried out through chemical reaction, and after 10 hours, it increases to 14%. From the results of Test Example 1, it can be seen that when potassium dioxide (KO2) and calcium hydroxide (Ca(OH)2) are mixed in the present invention, carbon dioxide is converted into oxygen through chemical reaction.

[0076] Test Example 2 (Optimal Oxygen Generation Ratio)

[0077] As shown in Table 1, the ratio of potassium peroxide (KO2) to calcium hydroxide (Ca(OH)2) was changed, and the total weight of each different ratio was set to 5g. The oxygen generation of each different weight ratio was tested. After understanding the oxygen generation, it was found that after testing the value of carbon dioxide, the oxygen generation increased as the carbon dioxide amount decreased. The results of the reduction of carbon dioxide over time are shown below. Figure 2 In addition, when detecting carbon dioxide, the test equipment using the substitution method in water was used to conduct normal temperature detection, and the amount of oxygen generated by different components was predicted through the detection of carbon dioxide.

[0078]

Table 1

[0079] <![CDATA[KO2]]> <![CDATA[Ca(OH)2]]> Ratio 1 7 3 Ratio 2 6 4 Ratio 3 5 5 Ratio 4 4 6 Ratio 5 3 7

[0080] From Figure 2The results shown confirm that when the ratio of potassium peroxide (KO2) to calcium hydroxide (Ca(OH)2) is 7:3 ratio (ratio 1) and 6:4 ratio (ratio 2), the reduction of carbon dioxide is the fastest and the reduction is the most. And, it has been confirmed that when the ratio of potassium peroxide (KO2) to calcium hydroxide (Ca(OH)2) is 5:5 ratio (ratio 3) and 4:6 ratio (ratio 4), the reduction of carbon dioxide is faster than that of 3:7 ratio (ratio 5), and more oxygen is generated. It can be confirmed that in the ratio content ratio range of the present invention, a large amount of oxygen is generated quickly while rapidly reducing carbon dioxide. Therefore, it can be confirmed that the weight ratio of the potassium peroxide to the calcium hydroxide is in the range of 8:2 to 4:6, and oxygen is generated extremely effectively. It is confirmed that, preferably, it is in the range of 8:2 to 5:5 or the range of 7:3 to 5:5 or the range of 7.5:2.5 to 5.5:4.5, and most preferably, it is in the range of 7:3 to 6:4, and the oxygen generation effect is good. In addition, when the content of potassium peroxide is too high and exceeds the ratio of 8:2 (for example, when it is equal to the ratio of 9:1), calcium hydroxide and the water generated in the primary reaction become powdery compounds and gelatinization reaction, which has the problem of delayed reaction. Therefore, the range of 8:2 to 4:6 is appropriate.

[0081] Test Example 3 (Test of oxygen generation trend of manganese dioxide and silicon dioxide)

[0082] In the state of mixing potassium peroxide 3.5g and calcium hydroxide 2.1g, the contents of manganese dioxide (MnO2) and silicon dioxide (SiO2) were set to the proportions shown in Table 2 below, and the amount of oxygen generated was detected. The results are shown below. Figure 3 middle.

[0083]

Table 2

[0084] <![CDATA[KO2]]> <![CDATA[Ca(OH)2]]> <![CDATA[MnO2]]> <![CDATA[Silicon dioxide (SiO2)]]> Ratio 6 3.5g 2.1g - - Ratio 7 3.5g 2.1g 1g - Ratio 8 3.5g 2.1g 1.5g - Ratio 9 3.5g 2.1g 1g 0.75g Ratio 10 3.5g 2.1g 1g 1.5g Ratio 11 3.5g 2.1g 0.5g 1.5g

[0085] like Figure 3 As shown in the figure, the situation when manganese dioxide was added and not added was compared, and it was confirmed that more oxygen was generated. That is, it was confirmed that the amount of oxygen generated in the ratios 7 and 8 was greater than when manganese dioxide was not added in the ratio 6. In addition, it was confirmed that the amount of oxygen generated in the ratios 9 to 11 with a small amount of silicon dioxide added was greater than that in the ratios 7 and 8 with manganese dioxide added and silicon dioxide not added.

[0086] Test Example 4 (Reaction Temperature Test)

[0087] In a state where 3.5 g of potassium peroxide and 2.1 g of calcium hydroxide were mixed, they were reacted with water, and the temperature that appeared over time was measured. The results are shown below. Figure 3 In. Figure 3As shown, in a state where potassium peroxide and calcium hydroxide are mixed, they are reacted with water to generate oxygen. At this time, it is confirmed that during the reaction, a high temperature is exhibited due to a rapid exothermic reaction.

[0088] Test Example 5 (Controlled Heating Response Test)

[0089] In the oxygen generating composition, 3 g of potassium peroxide (KO2) was mixed with 2 g of calcium hydroxide, and the content of potassium nitrate (KNO3) was changed to 3.0 g, 6.0 g, 9.0 g and 12.0 g respectively, and the temperature generated over time was detected. The results are shown below. Figure 5 middle.

[0090] like Figure 5 Compared with the case where potassium peroxide was added and not added, Figure 3 , which can reduce the initial heat generation and cool it down during the whole time. In addition, it has been confirmed that when 12.0g of potassium nitrate is mixed with 3g of potassium peroxide, the heat of reaction can be absorbed and the exothermic reaction can be reduced compared with other contents, and the oxygen generating composition can be applied more stably due to the cooling. When the potassium nitrate exceeds 5 times the potassium peroxide, although the exothermic reaction can be suppressed, gelatinization may occur, which may reduce the amount of oxygen generated, and the amount of oxygen generated is the main purpose of the oxygen generating composition. Therefore, preferably, the potassium chloride is contained in a range of 3 to 5 times the weight ratio of the potassium peroxide, for example, the potassium nitrate or the potassium chloride is contained in a range of 3.5 to 4.5 times the weight ratio of the potassium peroxide. In the range, the exothermic reaction can be suppressed, the reaction temperature can be lowered, the oxygen generating composition can be used stably, and sufficient oxygen can be generated.

[0091] Test Example 6 (Reaction Rate Test Using Sodium Bicarbonate)

[0092] In a state where 3.5 g of potassium peroxide and 2.1 g of calcium hydroxide were mixed, and then sodium bicarbonate (NaHCO3) was mixed without mixing, and then mixed with water, the amount of oxygen generated was detected, and the results of the amount of oxygen generated over time are shown below. Figure 6 In. Figure 6 As shown, it has been confirmed that oxygen can be generated more quickly when sodium bicarbonate is added than when no sodium bicarbonate is added. The reason is that the KOH generated by the chemical reaction between potassium peroxide and calcium hydroxide and carbon dioxide (CO2) and water (H2O) reacts with sodium bicarbonate (NaHCO3) to undergo an acid-base reaction and is removed, which further shifts the direction of the reaction to the product. It has been confirmed that the addition of sodium bicarbonate can make the reaction proceed faster and oxygen can be generated immediately in critical situations.

[0093] In addition, the present invention provides a device comprising the oxygen generating composition. The device comprising the oxygen generating composition of the present invention is described below.

[0094] The device described in one embodiment of the present invention may be a mask, which is in the following form: the oxygen generating composition is placed inside an end cap, and the end cap is attached to the filter of the mask. The end cap may include a mask layer so that when the mask is not in use and in storage, it is blocked from the outside and does not generate oxygen, and when the user uses the mask, the mask layer is separated from the end cap body, and oxygen is generated when the mask layer is separated. Thus, as described above, the oxygen generating substance begins to react with carbon dioxide sprayed from the mouth or nose of the user, and as a result, oxygen is generated for the user to inhale.

[0095] For example, the amount of potassium peroxide can be increased so that the oxygen generating composition can generate oxygen for a longer time when installed in a respiratory mask and used, and calcium hydroxide (Ca(OH)2) is included in the range of 20 to 30 parts by weight and potassium nitrate (KNO3) or potassium chloride (KCl) is included in the range of 30 to 50 parts by weight relative to 100 parts by weight of potassium peroxide (KO2), for example, KO25.0g, Ca(OH)21.25g and KCl2g. When the oxygen generating composition is stored in a respiratory mask with a separate end cap and used, the amount of potassium peroxide can be increased, thereby allowing it to generate oxygen for a long time, and a small amount of potassium chloride is added to control the initial calorific value.

[0096] In addition, the filter of the mask can be in a state of being immersed in a solution, so as to block harmful gases from the outside. In this case, the mask can be used as a gas mask for use in emergency situations such as fires. In this case, it is convenient for the user to wear the gas mask on his face, breathe oxygen with both hands free, and move to a safe place more quickly.

[0097] The device described in another embodiment of the present invention can be an oxygen-generating towel, which contains the oxygen-generating composition inside a storage cap, and the storage cap is combined with a towel-shaped cloth. The oxygen-generating towel can be in the following form: the towel itself is composed of multiple filter layers and is impregnated with a solution for blocking harmful substances. It can also be in the following state: a storage cap for storing the oxygen-generating substance is combined with the oxygen-generating towel. In addition, as in the mask, one side is combined with a mask layer. When the user is in a critical situation, the mask layer is separated to expose the oxygen-generating substance contained inside to the outside (separate the mask layer and open it), thereby generating oxygen, allowing the user to inhale the oxygen generated in the exposed part.

[0098] Preferably, when the oxygen generating composition is installed in an oxygen generating towel for emergency rescue in fire and the like, manganese dioxide may be further added to generate more oxygen initially, and calcium hydroxide (Ca(OH)2) may be contained in a range of 40 to 50 parts by weight, manganese dioxide may be contained in a range of 20 to 40 parts by weight, and potassium nitrate (KNO3) or potassium chloride (KCl) may be contained in a range of 80 to 120 parts by weight relative to 100 parts by weight of potassium peroxide (KO2), for example, KO2 3.0 g, Ca(OH)2 1.2 g, MnO2 1.0 g, and KCl 3 g. When the oxygen generating composition is stored in a separate end cap of an oxygen generating towel for emergency use, the manganese dioxide may be added to generate a large amount of oxygen immediately, and potassium chloride may be further contained to control the calorific value in order to suppress the exothermic reaction caused thereby.

[0099] In addition, another embodiment of the device using the oxygen generating composition of the present invention is a gas mask, which includes: an end cap, which contains the oxygen generating composition, a harmful gas filter layer, and the oxygen generating composition, and is combined with the harmful gas filter layer; and a hanging rope, which is combined with the two ends of the filter layer to facilitate the user to hang it on the ear. The harmful gas filter layer includes: an MB filter, which is composed of a melt-blown filter; a plurality of auxiliary filters, in which the MB filter is sandwiched, which are arranged on both sides of the MB filter and are composed of a material containing activated carbon in a polypropylene material; an outer layer, which is arranged on the outside of the plurality of auxiliary filters and is composed of artificial fibers; and a natural extract contained in the filter layer, the natural extract includes: one or more selected from the group consisting of the following extracts: propolis extract, green tea extract, tea tree extract, lavender extract, rosemary flower extract, peppermint extract, mint leaf extract, chamomile extract and water lotus extract.

[0100] The gas mask is formed with a harmful gas filter layer, and the harmful gas filter layer contains natural extracts to block external harmful gases, and in critical situations such as fire, prevent harmful gases from flowing into the user's respiratory organs, and the oxygen generating substance generates oxygen for the user's respiratory organs, which can maximize the user's long-term survival. Further, the two ends of the gas mask of the present invention are combined with hanging ropes for the user's ears, so that not only can harmful gases and oxygen delivery be blocked, but the user does not need to handle it with his hands, which is more convenient to avoid.

[0101] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the scope of the claims of the present invention will not be limited by these contents. It is obvious to those skilled in the art that various modifications and variations can be made without departing from the scope of the technical idea of ​​the present invention in the claims.
