A cylinder filled with oxygen is used, but it is large, not easy to use, and expensive. For this reason, an oxygen generator that is easy to use is desired.

In order to meet this requirement, Japanese Unexamined Patent Publication No. 54-93
There is one shown in Publication No. 896. This method generates oxygen using a chlorate mixture, and in this respect has the advantage that it can be used more easily than the method using an oxygen cylinder. However, the device shown here requires the removal of harmful impurities such as chlorine gas, and in order to absorb these and ensure the safety of the device, a complex and expensive device is required. turn into.

Here, in JP-A-54-26990, sodium percarbonate (NazcO3.3/2Hto2

[Object of the Invention J The present invention has been made in view of the above points, and
The purpose is to provide an oxygen generating device that can remove harmful hydrogen peroxide and the like and easily ensure safety as a device.

DISCLOSURE OF THE INVENTION Accordingly, the oxygen generating device according to the present invention includes sodium percarbonate 3, manganese dioxide or iron used as the catalyst 4,
Add metal salts such as copper and lead to water 5 and generate oxygen.
In an oxygen generator in which an oxygen generating section 8 and a suction section 7-9 are separated via a filter 15, the filter 1
5 is composed of a large number of micropores with a diameter of 3 to 5 μ-.
The above objective is achieved by passing through the filter 15 provided with a large number of micropores of ~5 μm to remove undecomposed hydrogen peroxide mist, carbon dioxide, manganese dioxide powder, etc. This is what I did.

The present invention will be described in detail below based on illustrated embodiments.

1 to 4 show an embodiment of the present invention, in which a container 1 formed into a bottomed cylindrical shape with an open top is made of a material such as polypropylene or polyethylene by blow molding or the like. Water 5 containing an aromatic agent is placed inside the container. A hollow cap 2 is fitted into the upper part of the container 1 and sealed by adhesion or welding to prevent water 5 in the container from leaking. This cap 2 is formed by Innoexi H blow molding or the like, and the small diameter lower end opening of the cap 2 is covered with an isolation film 7 made of polyethylene terephthalate film, aluminum foil, or a product N film of these. Suppose that it is pasted. The lower side of the cap 2 inside the container 1 serves as an oxygen generating section 8. On the other hand, an oxygen outlet 21 surrounded by a thin wall portion 11 is provided at the center of the upper surface of the cap 2, and a filter 15 is installed inside the oxygen outlet 21.
A planter 16 is suspended from the cap 1 into the cap 2. Furthermore, this cap 2 is integrally provided with a cover 22 in which a plurality of ventilation holes 17 are perforated, and the connection part between one end edge of the cover 22 and the cap 2 is used as a hinge part, and the cover 22 is inserted as shown in FIG. It is said to be reminiscent of something that happens.

When the cover 22 is opened, the suction section 7-9 is moved to h1 along with the side pieces 12 hanging down from both sides of the cover 22.
A notch 14 is provided in the cover 22 to prevent the nose from touching the nose.

Sodium percarbonate 3 is housed in the upper part of this cap 2, and catalyst 4 is housed in an isolation container 6 which is placed in the small diameter part at the bottom end of cap 2 and has an open bottom. It is housed in the cap 2 while being separated from the catalyst 4 by a container 6. Here, as the catalyst 4, in addition to manganese dioxide and iron as mentioned above, copper, nickel, cobalt, manganese, chromium,
Powders of metal salts such as lead, pananoum, tungsten, or their compounds are used, and these are prepared as solids coated with water-soluble substances that have different disintegration times in water, and then poured into water with sodium percarbonate3. When this occurs, oxygen is generated constantly within a certain period of time. The most preferable release means is one that simultaneously releases the isolation layers between the storage compartments, but it is also possible to use a method in which a catalyst such as water, sodium percarbonate, manganese dioxide, etc. is placed in the container at the time of use.

However, in this oxygen generator, take out the packaging device 3 shown in Figure wS1, open the cover 22 by raising it up as shown in Figures 2 and 4, and then push in the oxygen outlet 21. For example, the plunger 16 and isolation container 6 push and break the isolation film 7 whose peripheral edge is fixed to the lower opening edge of the cap 2, and the gap between the lower ends of the cap 2 is broken.
In order to open it, the isolation container 6 containing the catalyst 4 falls into the water 5 and the sodium percarbonate 3 also falls into the water.

Here, the lower opening edge of the isolation container 6 that breaks the isolation film 7 is serrated. As a result, sodium percarbonate 3 is decomposed by the action of contact v&4, and oxygen is generated.
Oxygen is discharged from the oxygen discharge port 21 through the inside of the cap 2, and the user injects a mixture of oxygen discharged from the oxygen discharge port 21 and outside air sucked in from the vent 17 into the suction section 7-9. You will inhale it from put it here,
A filter 15 having a large number of micropores of 3 to 5 microns is installed in the oxygen outlet 21, and the filter 15 isolates the oxygen generating section 8 and the suction section 7-9. , it is possible to prevent mist etc. from passing through when oxygen is generated, and it is also possible to prevent water from coming out when falling. That is, although most of the gas generated within the container 1 is oxygen, some hydrogen peroxide may remain undecomposed and turn into a mist or gas.
It is said that when the atmosphere contains 1 to 2 ppm or more of peroxide water X, lys, it has an adverse effect on the human body. In addition, manganese dioxide powder (particle size of about 10 μm) used as a catalyst and a mist of aqueous sodium carbonate solution after the reaction may also be released into the atmosphere. This manganese dioxide is present in the atmosphere at a concentration of 5mg/
It is said that if it contains more than m', it will have an adverse effect on the human body. Also, since sodium carbonate has a pH of 11 and is highly alkaline, it irritates the skin, mucous membranes, eyes, etc. For this reason, the filter 15 is water repellent to aqueous solutions.
In addition, the sodium carbonate solution may pass through the filter 15 due to its water repellency, whether it is made of tetrafluoroethylene resin, polyethylene resin, etc., which have micropores that are 3 to 5 μm smaller than the 10 μm particle size of manganese dioxide. Furthermore, the manganese dioxide particles also do not pass through the fine pores of the filter 15, and the hydrogen peroxide mist and gas are decomposed by the many fine pores and are prevented from exiting the container 1. If the diameter of the micropores of the filter 15 is less than 3μ-, the ventilation resistance of the filter 15 becomes large, making it difficult for oxygen to be released from the inside of the container 1;
If the amount exceeds the above, the effect of removing the hydrogen peroxide mist and manganese dioxide powder will be reduced.

Further, in the present invention, an aromatic agent is placed in the water 5, so that the odor of the aromatic agent is added to the oxygen discharged from the oxygen discharge port 21. If there is an odor from the fragrance, the user will know that oxygen is being generated. As this aromatic agent, solid 7-ohm urethane impregnated with a fragrance, a mixture of a water-soluble substance such as alcohol and a fragrance, or a mixture of an oil-based substance and a fragrance can be used. The odor of the agent may be selected from citrus, non-tall, forest odor, etc., depending on the purpose of use and preference, and components such as phytoncide may be added.

In addition, FIG. 5 and PIS 6 show other embodiments,

However, in the embodiment shown in FIG. 5, the urethane 7-sum 18 is impregnated with fragrance, and a thin film filter made of tetrafluoroethylene resin or polyethylene resin is coated on both sides of the urethane 7-sum 18. 19 is laminated to form a filter 15. In the embodiment shown in FIG. 6, a thin film filter 19 is laminated on the lower surface of a urethane membrane 18 impregnated with fragrance. . If this is done, the scent of the fragrance will be emitted along with the oxygen when oxygen is generated, making it possible to confirm the oxygen generation and provide a psychologically refreshing feeling.

[Effect of the invention J As described above, in the present invention, the oxygen generating part and the suction part 7
In an oxygen generator that separates hydrogen peroxide and manganese dioxide through a filter, the filter is composed of a large number of micropores of 3 to 5 μm in size, so harmful mist of hydrogen peroxide and manganese dioxide are generated. The powder and the mist of the sodium carbonate aqueous solution after the reaction can be removed with a filter, and the safety of the oxygen generator can be ensured with a simple configuration. Moreover, by adding a fragrance or the like to the water in the container or impregnating the filter with a fragrance, the generation of oxygen can be detected, which can provide a psychologically refreshing effect.
