Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple portable oxygen generator, and more particularly to a multi-chamber container in which a mixing liquid and a mixing base for generating oxygen by mixing are separately housed. And an oxygen generator that mixes at the time of use to generate oxygen.

[0002]

2. Description of the Related Art In recent years, as a portable simple oxygen generator not using an oxygen cylinder, an oxygen generating base such as sodium percarbonate and water are mixed in the presence of a catalyst, and oxygen is decomposed by a hydrogen peroxide decomposition reaction. There have been many proposals for generating. For example, Japanese Patent Application Laid-Open Nos. 4-154603 and 6-1
No. 07401, water is stored in a reaction tank and a washing tank, respectively, and a solid oxygen generating base and a catalyst are charged into the water in the reaction tank to wash the oxygen-containing gas generated by the decomposition reaction. Released as fine bubbles in the water of the tank, the mist of sodium carbonate was removed in the water of the washing tank, the water contained in the gas was removed using a filter in the flow path, and oxygen was taken out from the outlet. I have. Such an oxygen generator requires a container having a completely isolated reaction tank and a washing tank.

As a portable oxygen generator without a washing tank, for example, Japanese Utility Model Laid-Open No. 4-40650 discloses a plurality of oxygen generators divided by a partition wall capable of communicating a solid oxygen generating base, a catalyst and water. Oxygen generators that are housed separately in different housing chambers have been proposed. In this oxygen generator, only a component necessary for generating a predetermined amount of oxygen is stored in a flexible container, and a filter is mounted on the upper portion of the container instead of providing a washing tank. Here, mist such as sodium carbonate and water can be removed by extracting the generated oxygen through a filter. In such an oxygen generator, when the container is tilted or vibrated, or when air bubbles are generated by mixing the components and the level of the foaming liquid rises, a large amount of the mixed liquid is directly filtered. Contact Therefore, by using a filter having water repellency, the mixed liquid inside is prevented from flowing out.

However, a water-repellent filter can maintain water-repellency even when it comes into contact with water, but its water-repellency decreases when it comes into contact with an alkaline liquid. However, the aqueous solution of sodium percarbonate in the mixed solution is alkaline. Therefore, if a large amount of the mixed solution comes into contact during use, the water repellency is reduced, and moisture penetrates into the pores of the filter. As a result, the filter is closed and the oxygen permeability is deteriorated. In particular, since a portable oxygen generator generates a small amount of oxygen, if the oxygen permeability of the filter deteriorates, the amount of oxygen released cannot be secured.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a portable oxygen generator in which the amount of released oxygen is less likely to decrease during use. . Another object of the present invention is to provide a portable oxygen generator having good operability during use.

[0006]

An oxygen generator according to the present invention for achieving the above object contains a mixing liquid and a mixing base which generates oxygen by mixing the mixing liquid with the mixing liquid in the presence of a catalyst. The oxygen generator having a discharge hole for releasing the oxygen, containing the mixing liquid, the mixing base, and the catalyst, and a liquid chamber containing the mixing liquid and the mixing base. A first container partitioned by a mixing partition wall capable of communicating with a base chamber to be accommodated, and a container accommodating the first container, wherein the first container is disposed on a discharge hole side of the first container. And a second container which is covered with a filter in a liquid-tight manner by an outlet for taking out oxygen released from the container.

According to the oxygen generator of the present invention, first, the mixing chamber of the first container containing the mixing liquid and the mixing chamber of the mixing base communicate with each other through the mixing partition wall. Oxygen is generated by mixing the mixing base and the catalyst, and this oxygen is released from the discharge hole into the second container while containing the mist and moisture. At this time, the liquid mixture in the first container may flow out of the discharge hole together with oxygen. Then, the oxygen gas and the mixed solution are temporarily retained in the second container, whereby a part of the oxygen gas and the mist and the mixed solution are separated by gravity, and further filtered by a filter. , Only oxygen is withdrawn from the outlet of the second container.

According to the present invention, since the first container is accommodated in the second container and the filter is attached to the outlet of the second container, the first container is provided with a filter for the oxygen released from the first container. The water and mist of the mixture can be separated in the second container to extract only oxygen, and the mixture in the first container does not directly adhere to the filter. Without penetrating into the fine pores and blocking the oxygen permeability. In addition, since the outlet of the second container is disposed on the discharge hole side of the first container, the discharge hole of the first container can be disposed on the upper side by disposing the outlet of the second container on the upper side during use. Therefore, the mixed liquid is hardly released from the discharge hole, and the mixed liquid is less likely to adhere to the water-repellent filter.

Further, in the present invention, by providing the discharge hole of the first container in a discharge chamber partitioned by a dischargeable partition wall, the contents of the first container can be stored or transported. It can be prevented from being discharged into the second container. Further, in the first container, if the chamber for storing the liquid for mixing is arranged on the discharge hole side with respect to the chamber for storing the base for mixing, if the discharge hole is arranged on the upper side during use, the liquid for mixing is used as the base for mixing. It can be easily moved to the mixing side, and even if the mixing base is a powder or a liquid with low fluidity, the entire amount of the mixing base can be reliably mixed with the mixing liquid.

When the first container is housed in the second container, the user cannot touch the first container without opening the second container. By allowing the mixing partition wall of the first container to communicate with the second container via the second container, it is possible to operate the second container without opening the container, thereby improving operability during use.
In particular, when the mixing partition wall is formed by welding the resin layer on the inner wall surface of the first container so as to have easy peelability, the mixing partition wall is communicated only by pressing from the outside of the second container. Operability at the time of use can be improved.

When the discharge hole of the first container is closed by a discharge partition wall, the discharge partition wall is formed by welding the resin layer on the inner wall surface of the first container so as to have easy peelability. Then, if the mixing partition wall of the first container is communicated, the internal pressure is increased by oxygen generated from the mixed solution, and the internal pressure allows the communication of the discharge partition wall. Work is not required, and operability during use is improved.
Furthermore, when both the partition wall for mixing and the partition wall for release are welded so that the resin layer on the inner wall surface of the first container has easy peelability, the release partition wall has a higher peel strength than the partition wall for mixing. With this configuration, the order of communication between the two can be regulated, and the partition wall for discharge communicates first, and the contents of the first container are unnecessarily discharged from the discharge hole into the second container. There is no.

In the present invention, the mixing partition wall may be
A first partition section for partitioning the liquid chamber and the base chamber;
Alternatively, if the catalyst chamber is configured to include a second partition part that separates the catalyst chamber from the base chamber, the catalyst and the mixing base can be separated and stored, so that a small amount of the catalyst and the mixing base are released from the mixing base. It is possible to reliably prevent the components from reacting upon contact with the catalyst. In particular, when the first and second partition portions are provided continuously, when one of the first and second partition portions is peeled off at the time of use, the other partition portion continuous with the partition portion is continuously peeled off. Therefore, the mixing partitioning section that partitions the three or more storage chambers can be reliably communicated, and the operability during use can be further improved.

[0013]

Embodiments of the present invention will be described below. FIG. 1 is a front view showing an embodiment of the oxygen generator of the present invention, and FIG. 2 is a longitudinal sectional view thereof. In the drawing, reference numeral 10 denotes an oxygen generator, which includes a first container 1 containing a mixing liquid, a mixing base, and a catalyst, and a second container 2 containing the first container 1. ing. In the oxygen generator 10, the mixing liquid and the mixing base can be selected by appropriately combining substances that generate oxygen by mixing both in the presence of a catalyst. For example, a combination of an aqueous solvent as a liquid for mixing and sodium percarbonate as a base for mixing can be exemplified. The aqueous solvent is a liquid containing water, and may be water or an aqueous solution, and may contain other components such as a preservative and a coloring agent. Furthermore, it may be a suspension or a mixed solution containing a component that does not dissolve in water. The sodium percarbonate is a substance that generates hydrogen peroxide when mixed or dissolved with the aqueous solvent, and may be sodium percarbonate alone or may contain other components. As a form, a powder is preferable because it is easily mixed with an aqueous solvent, but a solid or bulk solid can be used.

[0014] The catalyst is a substance having a catalytic action for generating oxygen by mixing a mixing liquid and a mixing base. In the case of a combination of an aqueous solvent and sodium percarbonate, the catalyst is generated from sodium percarbonate. Catalase, manganese chloride, manganese dioxide, and the like that exhibit a catalytic action in the decomposition reaction of hydrogen peroxide can be exemplified. First container 1
Is formed by welding a resin-made inflation tube into a flat shape, and has an innermost layer made of a mixture of polyethylene and polypropylene. This first
The container 1 is tightly welded at both ends 3a and 3b in the vertical direction in the figure, so that the periphery is airtightly closed, and furthermore, the innermost layer is welded so as to have easy peelability so as to partition the middle part up and down. A discharge partition 5 and a mixing partition 6 that can communicate with each other are formed. The mixing partition 6 includes a first partition 6a and a second partition 6b continuous from the first partition 6a. The peel strength of the release partition 5 is made higher than the peel strength of the mixing partition 6 by making the partition thicker or providing a plurality of partitions.

The release partition 5 and the first and second partitions 6a, 6b provide a discharge chamber 8 having a discharge hole 7 for releasing oxygen at the end 3a side, and a discharge chamber 8 below the discharge chamber 8. A liquid chamber 9 arranged on the side and containing an aqueous solvent, a base chamber 11 arranged below the liquid chamber 9 and containing sodium percarbonate powder, and also arranged below the liquid chamber 9 And a catalyst chamber 12 containing a catalyst. First
The shape, size, number and the like of the discharge holes 7 provided in the discharge chamber 8 of the container 1 can be appropriately set, and an opening area capable of easily releasing oxygen generated at the time of use can be secured, and the contents can be easily reduced. It is preferred that it is not so eluted. The position of the discharge hole 7 may be higher than the liquid level of the contents at the time of use. However, since the contents are foamed and the foaming liquid level rises at the time of use, the upper end of the first container 1 is moved upward. 3a
It is preferable to arrange on the side, that is, on the upper end 3a or in the vicinity thereof. Further, the discharge hole 7 may be provided on a part of the wall surface of the discharge chamber 8, but if provided on both opposing wall surfaces, when the oxygen generator is tilted or placed horizontally during use, one of the wall surfaces will have the contents. Even if it is arranged inside and closed, the other wall surface is arranged above the liquid level, so that it is possible to secure an oxygen release path, which is preferable.

The second container 2 for accommodating the first container 1 is made of a flexible resin, and is preferably a flat container. In the second container 2 of this embodiment, an outlet 15 for taking out the generated oxygen is arranged on the side of the discharge hole 7 of the first container 1, and the upper and lower ends 16 and 17 are welded to each other with a high strength and the outer portion is formed. The surrounding area is closed. The second container 2 has a width that can prevent the first container 1 from falling and tilting inside, for example, several meters from the width of the first container 1.
It has a width greater by m to several cm. In addition, a string member 27 is attached to the oxygen extraction unit 15 for use by hanging it around a user's neck or the like. The oxygen extracting portion 15 has a nozzle 18 having a vent and a filter 19 covering at least one end of the vent, and the filter 19 is filled with activated carbon. The shape of the nozzle 18 can be arbitrarily selected, and for example, a member for a user to suction can be attached to the nozzle 18. Also, the filter 19
Is not particularly limited as long as it has a large number of pores that do not allow micelles or water droplets of sodium carbonate generated at the time of use to pass therethrough, and can ensure a sufficient oxygen passage amount. In addition, when the liquid for mixing is an aqueous solvent, it is preferable to use a water-repellent filter. In this case, even if the material itself has water repellency, a material having no water repellency is provided with water repellency. There may be.

In order to manufacture the oxygen generator 10 having such a configuration, the discharge hole 7 is formed on the upper end portion 3a side using a cylindrical resin molded body, and the first partition portion of the mixing partition portion 6 is formed. 6a and the second partition 6b are welded so as to have easy peelability, sodium percarbonate and the catalyst are accommodated in the base chamber 11 and the catalyst chamber 12, respectively, and the lower end 3b is welded strongly. on the other hand,
An aqueous solvent is accommodated in the liquid chamber 9 from the upper end 3a side, the release partition 5 is welded so as to have easy peelability, and the upper end 3 is welded strongly. When the oxygen generator 10 manufactured in this manner is used, the first partition 6 and the second partition 6b are welded with easy peelability. Container 2
By pressing the liquid chamber 9 from outside the mixing chamber 6
The first and second partition portions 6a and 6b are peeled off to communicate with each other. At this time, since the release partition 5 has a higher peel strength than the mixing partition 6, it does not peel.

First and second partition walls 6 of the mixing partition 6
When a and 6b are communicated with each other, since the liquid chamber 9 is disposed above the base chamber 11 and the catalyst chamber 12, all the aqueous solvents in the liquid chamber 9 descend to the positions of the base chamber 11 and the catalyst chamber 12. . This mixes the aqueous medium, sodium percarbonate, and the catalyst. When sodium percarbonate is mixed with the aqueous solvent, hydrogen peroxide is generated from the sodium percarbonate. The oxygen generator 10 generates oxygen by decomposing such hydrogen peroxide by the action of a catalyst contained in an aqueous solvent, such as catalase or manganese dioxide. In addition,
When manganese chloride is used as a catalyst, manganese chloride itself does not exhibit a catalytic action, but the precipitation of manganese carbonate generated by the combination of manganese ions generated from sodium percarbonate and manganese chloride by mixing. The substance exhibits a catalytic action.

When oxygen is generated, the internal pressure in the first container 1 increases, and the pressure causes the release partition 5 that separates the liquid chamber 9 and the release chamber 8 to separate and communicate with each other. It is possible to discharge from the inside of the first container 1 to the inside of the second container 2 via the discharge hole 7. As a result, oxygen generated in the first container 1 is discharged from the discharge port 7 of the first container 1 through the second container 2.
Released into At this time, impurities such as water, chlorine, and micelles of sodium carbonate are also released from the release hole 7 into the second container 2 together with oxygen. Further, bubbles may be generated in the mixed liquid in the first container 1 and the level of the foaming liquid may rise, and a part of the mixed liquid may be discharged from the discharge hole 7 into the second container 2. In the oxygen generator 10, such discharged matter is once released and retained in the second container 2 to separate impurities by gravity. Then, the discharged matter discharged into the second container 2 is discharged from the extraction unit 15 to the filter 19.
And activated carbon. Therefore, the fine particles and water droplets which are not separated in the second container and flow together with oxygen are filtered by the filter 19, and a small amount of gas other than oxygen, such as hydrogen peroxide and chlorine, is contacted with the activated carbon and adsorbed. Removed. Accordingly, substantially only oxygen can be extracted from the nozzle 16, and the oxygen generator 10 can be used. At the time of use, after the communication operation of the partition portion 6, it can be used by hanging it on the neck of the user using the string member 27. At this time, since the discharge hole 7 of the first container 1 and the take-out portion 15 of the second container 2 are provided on the same end side, the take-out portion 15 is orientated upward by hanging with the string member 27. Then, the discharge hole 7 of the first container 1 can also be oriented upward, so that the discharge hole 7 is not buried in the mixture in the first container 1 and is not closed. Furthermore, the first
Since the container 1 and the second container 2 are flexible and have a flat shape, the container 1 and the second container 2 are easily adapted to the user's body, are easily stabilized, and are easy to handle.

According to such an oxygen generator 10, the first
Since the water, mist, or mixed liquid released from the container 1 is once separated in the second container 2 and then oxygen is taken out, the mixed liquid and the like hardly adhere to the filter 18, so that the pores of the filter 18 Can be prevented from lowering oxygen permeability due to clogging of. In addition, since the outlet 15 of the second container 2 is arranged on the discharge hole 7 side of the first container 1, if the outlet 15 of the second container 2 is arranged on the upper side during use, the first container The first discharge hole 7 can also be arranged on the upper side, the mixed liquid is hardly discharged from the discharge hole 7, and the possibility that the mixed liquid adheres to the filter 18 is smaller. Further, the first container 1
Has a discharge chamber 8 partitioned by a discharge partition wall 9 that can communicate with the container, so that the contents of the first container can be transferred from the discharge hole 7 into the second container 2 during storage or transportation. It can be prevented from being released. Further, in the first container 1, the liquid chamber 9 is disposed closer to the discharge hole 7 than the base chamber 11, so that if the discharge hole 7 is disposed on the upper side during use, the mixing liquid will be closer to the mixing base. It can be easily moved, and even if the mixing base is a powder or a liquid with low fluidity, the entire amount of the mixing base can be reliably mixed with the mixing liquid.

Although the first container 1 is accommodated in the second container 2 in a liquid-tight manner, the partition wall 6 for mixing is the first container 1.
Since the resin layer on the inner wall surface of the second container 1 is welded so as to have easy peeling property, the partition wall 6 for mixing can be communicated only by pressing from the outside of the second container 1, and the second container 2
Can be operated without opening, and the operability at the time of use is good. In addition, since the release holes 7 of the first container 1 are welded so that the release partition walls 5 also have easy peelability, the release partition walls 5 can be communicated with oxygen generated during mixing, Communication work of the discharge partition wall 5 is unnecessary, and operability during use is good. Furthermore, since the discharge partition wall 5 has a higher peel strength than the mixing partition wall 6, the order of communication between the two can be regulated, and the discharge partition wall 5 communicates first to allow the first container 1 to communicate. The contents are not wastefully discharged from the discharge hole 7 into the second container 2. In addition, since the first partition 6a and the second partition 6b of the mixing partition 6 are provided continuously, the catalyst and the mixing base can be separated and stored, and the mixing can be performed. It is possible to reliably prevent a small amount of components released from the base material from coming into contact with the catalyst to progress the reaction, and to peel off one of the first partition portion 6a and the second partition portion 6b during use. And the other partition wall that is continuous with the partition wall can be continuously peeled off, and the mixing partition wall 6 can be reliably communicated, so that operability during use is good.

In the above-described embodiment, the first container has an inner layer made of a resin mixture having an easy peeling property and capable of being welded, and the inner layer is welded with an easy peeling property. In a multi-chamber container in which at least three or more chambers are partitioned by the formed communicable partition wall, the first communicable partition wall is continuous with the container end at both ends.
, And a multi-chamber container having a second partition wall that is continuous with the container end at one end and is continuous from the first partition wall. Alternatively, in combination with another container, it can be used for a container other than the oxygen generator, and can be used, for example, as a medical container. When used as a medical container, for example, a polyolefin-based resin, a polyvinyl alcohol-based resin, a polyacrylonitrile-based resin, a polyacrylic acid-based resin, a polyamide-based resin, or the like can be used as a material, and a polyolefin-based resin is particularly preferable. As this polyolefin resin, low,
Medium and low-density olefin resins such as high-density polyethylene and polypropylene; cyclic polyolefins; and two or more copolymers selected from lower olefin resins and / or cyclic polyolefins. Here, the resin mixture layer that is easily peelable and weldable is selected from resins having a suitable melting temperature difference, for example, a temperature difference of 8 ° C. or more from the resin material and having an appropriate compatibility. This is a layer made of a mixed resin mixture. By adjusting the welding temperature or the welding pressure, this resin mixture layer can be welded with ease of peeling or can be welded with high strength. Such a container presses a part of the accommodation chambers as described above, thereby forming the first
Since the partition part and the second partition part can be continuously peeled off at once, the communication operation is easy.

FIG. 3 is a front view showing an oxygen generator according to another embodiment, and FIG. 4 is a longitudinal sectional view thereof. In this embodiment, the other parts of the first container 1 are formed in the same manner as in the above-described embodiment. In the first container 1, the liquid chamber 9 and the base chamber 11 are partitioned by the partition wall 6 for mixing. This embodiment is different from the above-described embodiment in that a catalyst chamber is not formed and that a mixing base is stored in a base chamber 11 in a state of being stored in an inner bag 30 having an opening. Here, the catalyst is catalase, which is contained in the liquid chamber 9 together with the aqueous solvent. The inner bag 30 housed in the base chamber 11 of the first container 1 is formed in a flat shape from a flexible resin, and has an opening 22 at a lower end 21. The upper end 23 facing the liquid chamber 9 is closed with a large number of pores 24 that cannot pass through the aqueous medium in a large amount, and both end portions 25 are closed. In the oxygen generator 20, sodium percarbonate powder is contained in such an inner bag 30, but sodium percarbonate not contained in the inner bag 30 may be present in the base chamber 11.
The base chamber 11 of the first container 1 is provided with a locking portion 26 that can lock the outer wall of the inner bag 30.

The oxygen generator 2 provided with such an inner bag 30
0 is the same as that of the oxygen generator 10 of the above embodiment in terms of usage. However, since the inner bag 30 is provided and the upper end 23 of the inner bag 30 is substantially closed, even when the aqueous solvent is lowered by connecting the mixing partition wall 6 at the start of use, the excess amount is directly reduced. Since it does not come into contact with the entire amount of sodium carbonate and comes into contact with sodium percarbonate existing outside the inner bag 20 and sodium percarbonate exposed from the opening portion 22, oxygen is generated. Does not occur. Further, even after the mixing, the aqueous solvent gradually enters the inside of the inner bag 20 through the opening 22 or the sodium percarbonate is gradually discharged from the opening 22 so that the aqueous solvent gradually contacts to generate oxygen. be able to. Therefore, according to the oxygen generator 20, the same operation and effect as those of the above-described embodiment can be obtained, and further, the generation speed of oxygen is stabilized during use, and the generation time of oxygen can be lengthened.

FIG. 5 is a front view showing still another embodiment, and FIG. 6 is a sectional view thereof. This oxygen generator 40
However, the configuration is the same as that of the above embodiment except that the configuration of the first container is different. Here, the liquid chamber 9 is disposed below the base chamber 11 and the catalyst chamber 12, and the discharge hole 7 is provided in the catalyst chamber 12 without providing a discharge hole chamber. When manganese dioxide is used as a catalyst, a slight amount of hydrogen peroxide gas is generated from the sodium percarbonate powder stored in the base chamber 11 during storage, and when this gas comes into contact with the catalyst, the decomposition reaction of hydrogen peroxide occurs during storage. May progress. Therefore, in the oxygen generator 40, if the release holes 7 are provided in the base chamber 11 and the catalyst chamber 12, the base chamber 11 and the catalyst chamber 12 communicate with each other via the inside of the second container 2. Therefore, the emission hole is formed only on one side.

The oxygen generator 40 can be used in the same manner as in the above-described embodiment, and the same effects can be obtained. In each of the above embodiments, each configuration can be changed without departing from the spirit of the present invention.
For example, a flexible container made of a resin is used as the first container and the second container, but a container made of another material such as a hard container may be used. In addition, the first
In the container described above, it is preferable to form a partition that is welded so as to have easy peelability as a partition that can communicate, but other configurations are possible as long as the partition can be connected.
