[Detailed Description of the Invention] [Technical Field 1] The present invention relates to an oxygen generation device for assisting breathing and recovering from fatigue during emergencies or extreme sports, and in particular, an oxygen generation device using sodium percarbonate. It is related to the device.

[Background technology 1: Oxygen-filled cylinders are generally used as equipment for supplying oxygen in the event of a fire, an oxygen deficiency accident, or a hazardous outbreak, but these cylinders are large and easy to use. However, it is not possible and is expensive. For this reason, an oxygen generator that can be easily used is desired.

In order to meet this requirement, Japanese Unexamined Patent Publication No. 54-938
There is one shown in Publication No. 96. This method generates oxygen using a chlorate mixture, and in this respect it has the advantage of being easier to use than the method using an oxygen cylinder. however,
The system shown here requires the removal of harmful chlorine and other impurities, and in order to absorb these and ensure the safety of the device, it becomes complicated and expensive. .

Here, JP-A-54-26990 discloses sodium percarbonate A (Na2CO343/28202).
It has been shown that oxygen can be generated by contacting the catalyst with a suspension or an aqueous solution of the catalyst.

In this case, compared to the above-mentioned conventional example, it has the characteristics of being much easier to use, being safer and more reliable, and being inexpensive. However, even in this publication, there is no disclosure of the specific form in which sodium percarbonate and the catalyst are to be stored or used, and it is unclear how to commercialize a product that can actually be used. is awaited.

[Objective of the Invention] The present invention has been made in view of the above points, and its object is to easily store and use sodium percarbonate and a catalyst for oxygen generation. To provide oxygen generator.

[Disclosure of the Invention] Accordingly, the present invention provides a WS1 containing sodium percarbonate.
A storage section, a second storage section that stores a catalyst such as manganese dioxide or a metal salt, and a third storage section that stores water are provided in the container, and an opening means that opens the isolation layer between these storage sections. It is characterized by the fact that all the substances necessary for oxygen generation can be contained in a single container, and the oxygen generation reaction can be started immediately by simply opening the isolation layer using the opening means. is started.

As the catalyst here, in addition to manganese dioxide and iron as mentioned above, powders of metal salts such as copper, nickel, cobalt, manganese, chromium, lead, vanadium, tungsten or their compounds are used; A solid substance is coated with water-soluble substances each having a different disintegration time in water, and when it is put into water with sodium percarbonate, oxygen is generated in the feed stand within a certain period of time. The most preferable opening means is one that simultaneously opens the isolation layers between the storage sections.

The present invention will be described in detail below based on the illustrated embodiments.
Figures 4 to 4 show one embodiment of the present invention, which has a bottomed cylindrical shape with an open top, and the top opening is closed with a semi-dome-shaped cap 2 attached to the top end. Inside the container 1, there is placed sodium percarbonate 3 wrapped in an isolation layer 6 made of vinyl or aluminum material that partitions the interior of the container 1 into upper and lower parts. The isolation layer 7 applied to the upper surface of the layer 6 forms a chamber in which the catalyst 4 is housed. Water 5 is stored in the lower part of container 1.

The cap 2 is provided with a cylindrical part 28 which penetrates the isolation layer 6 and whose lower end opening reaches the storage part for the water 5 and in which a filter 9 is installed, and a hinge part 20 is provided on the outer surface. A hemispherical cover 22 covering the cap 2 is pivotally attached to the cap 2.

Although this cover 22 normally covers the cap 2, if the cover 22, which engages the protrusion 24 with the engagement groove 27 of the cap 2, is rotated, the cover 22 will cover the cap 2.
The catalyst 4 enters the container 1 through the groove 26 and breaks through the periphery of the isolation layer 6 and the isolation layer 7 with its pointed edge.
and percarbonate) into the water, and at this time, the gasket 25 attached to the cover 22
Since the groove 26 is sealed, the generated oxygen is transferred to the cylindrical portion 28.
The oxygen passes through the inside and is released from the oxygen release port 21 to the outside. The filter 9 installed in the cylindrical part 28 prevents mist etc. from passing through when this oxygen is generated, and also prevents water from coming out when falling. 6* formed by etc.
The semi-dome-shaped cap 2 functions as an inhalation mask.

Although it does not communicate with the inside of the container 1 containing the water 5, when the piston 31 is pushed in, the delaminations 6 and 7 at both corners are ruptured by this pressure, and the catalyst 4 and the sodium percarbonate 3 are poured into the water 5. As it falls, the oxygen release port 21 aligns with the hole 34 provided in the cylinder 33, and the generated oxygen is released to the outside through the oxygen release port 21. The amount by which the piston 31 is pushed is regulated by the engagement between the O-ring 32 and a groove on the inner surface of the cylindrical portion 33 .

In the case shown in FIG. 10, sodium percarbonate 3, catalyst 4, and water 5 are accommodated in the container 1 in the same manner as in the embodiments shown in FIGS. 1 to 4, but an opening means is provided. are different.

In addition, the lower end large diameter portion of the cylinder 40 is connected to the upper container 1.
By being press-fitted into the fitting cylinder 33 in 2, the internal volume of the catalyst 4 housing portion becomes smaller, and this pressure causes the isolation layer 7 to
is broken and the catalyst 4 falls into the water 5 through the holes in the isolation layer 6. In the figure, 41 is the inner surface of the isolation/I6 hole and the fitting cylinder 33
This is an O-ring that touches the inner surface.

In the case shown in FIGS. 18 and 19, a piston 31 penetrating the upper surface of the container 1 and freely movable up and down is provided with an oxygen release port 21 penetrating the container 1 at the lower end of the piston 31. The catalyst 4 is housed in the lower part of the piston 31, which has a large-diameter fitting part that fits into the hole of the isolation M6 core that partitions the interior into upper and lower parts, and further has a thin film isolation layer 7 stuck to the lower end opening. When the piston 31 is pushed in, the pores in the isolation layer 6 open and overcarbonate occurs.)+7um3
falls into the water 5, and the isolation layer 7 is torn by a protrusion 46 protruding from the lower edge of the hole in the isolation N6. In order to avoid an inadvertent pushing operation of the piston 31, an annular spacer 45 having a slit is fitted to the upper end of the piston 31. After removing the spacer 45, the piston 31 is pushed in and fabricated.

Still other embodiments are shown in FIGS. 20 and 22.

Here, a lower container 11 and an upper container 12 that can be rotated relative to the lower container 11 form a container 1, and the upper surface of the lower container 11 has a fan-shaped opening 50.
