Description

[Detailed description of the invention] (Field of application of the invention) TECHNICAL FIELD This invention relates to a portable oxygen generation device.

(Prior Art) In the event of a fire outbreak, an oxygen deficiency accident, or the generation of harmful gases, there is a need for an oxygen generating device that is easy to carry and safe for evacuation or rescue purposes.

Alternatively, even in non-emergency situations such as those mentioned above, due to exhaust gas from cars or air pollution inside closed buildings, the living environment surrounding us becomes deficient in oxygen, especially in urban areas. Experts have pointed out that oxygen is a cause of deterioration of human health, and there is an increasing need to intentionally control oxygen intake on a daily basis.

Furthermore, inhalation of oxygen can also be used in cases of overwork, hangover, jet lag, etc. It is well known that fh has an extremely excellent healing effect. 4 Therefore, chemically reactive substances (e.g., sodium percarbonate,
A decomposition catalyst (composed of a combination of decomposition catalysts coated with a water-soluble substance) is reacted with water in a small, portable reaction tank to generate oxygen, which is then taken out to the outside via a humidifying tank filled with water. An oxygen generator was developed that was configured to allow oxygen to be inhaled.

However, as the reaction progresses after the start of the reaction with water, a kind of bumping state occurs, and water vapor or boiling water is ejected from the reaction tank into the humidifying tank through the communication pipe, contaminating the inside of the humidifying tank, and leaking to the outside. The problem was that the oxygen that was extracted had an odor.

In addition, in the case of bumping, the temperature and pressure within one reaction tank would increase rapidly, and as a result, there was a sufficient risk of explosion.

(Technical Problem) The technical problem of the present invention is to
It is possible to prevent the water in the humidifying tank from being contaminated as much as possible.
Furthermore, it is an object of the present invention to provide a portable oxygen generator configured to ensure sufficient safety even in the event of bumping.

(Technical Means) In order to achieve the above-mentioned technical problem, the present invention involves reacting a chemical reactant that causes a reaction and generates oxygen when mixed with water with water in a small portable reaction tank. In this device, a reserve tank is provided between the reaction tank and the humidification tank, and a reserve tank is provided between the reaction tank and the humidification tank, and the oxygen is generated through a humidification tank filled with water. It is an object of the present invention to provide a portable oxygen generating device configured such that the oxygen generated in the humidifying tank is sent to the humidifying tank via a reserve tank.

(Embodiment) According to the drawings, the portable oxygen generating device according to the present invention consists of a case body 1 and a lid body 2 hinged to the case body l, and this lid body 2 has an inner top portion. Backing sheet 3
It is a box-shaped synthetic resin item with a frame-shaped protrusion 4 attached at the approximate center of the inner top, and a disc-shaped seal protrusion adjacent to the protrusion 4. 5 is provided,
A locking 1F lever 7 having a locking portion 6 at its tip is attached to the front surface and is biased to rotate in one direction by a spring (not shown).

The case body 1 is, for example, a box-shaped one made of synthetic resin. Inside the case body 1, there is a reaction tank 8 approximately in the center, a reserve tank 9 surrounding the reaction tank 2, and a reserve tank 9. Adjacent to one side of the reserve tank 9 is a humidifying tank lO.
Each tank is open at the top. A shelf-like portion 8 is provided inside the upper part of the reaction tank 8.
The upper part of the reaction tank 8 and the upper part of the reserve tank 9 are communicated with each other through a communication hole 11.

A communication pipe 13 is attached to the humidification tank 10 side through a communication hole 12 provided in the upper part of the reserve tank 9, and the tip of this communication pipe 13 reaches the inner bottom of the humidification tank 10.

Furthermore, the front part of the case body l is provided with a recessed part 1a,
This recess 1a has an engaging part! b is provided.

On the other hand, a cartridge 14 for storing a chemical reaction substance is fitted into the top of the first reaction tank 8 .

This cartridge 14 has a water filling hole 15 and a capsule storage case 18, and this capsule storage case 1B has a bottom plate 1.
It has a structure in which the capsule storage case 1B is fitted with the capsule storage case 1B, and the inside is coated with a water-soluble substance such as sodium percarbonate 17 and a water-soluble substance stored in the case 18 that combines the two. Decomposition catalyst for certain manganese dioxide etc. 18
are stored in layers.

Next, to explain a usage example, if the cartridge 14 has been fitted to the upper part of the reaction tank 8 in advance, it will remain as it is; if not, this cartridge 14 will first be fitted.
After fitting the tank into the upper part of the reaction tank 8, water is poured into the water injection hole 15 and the upper part of the humidifying tank 10. To determine the amount of water to be poured into the case, if the case body is made of transparent material, provide a water level line to make it easier to see, or if not, prepare a water tank with a certain amount of water injected in advance. This is desirable.

Incidentally, since the cartridge 14 itself is removable, water equalization lines may be drawn inside the reaction tank 8 and the humidifying tank IO. Of course, in this case, the reaction tank 8 requires the amount of water necessary for the reaction, but the humidification tank 1
It should also be taken into consideration that in the case of 0, it is better to fill the tank with water to one ton rather than half. There is no need to change the water in the humidifying tank IO every time it is used.

Once the appropriate amount of water has been injected, close the lid 2 and press down strongly on the front side. The protrusion 4 provided on the inner nape of the lid 2 will push the lid tab fitted onto the top of the capsule storage case 16. The pressed bottom plate lea comes off and the sodium percarbonate 17 and decomposition catalyst IB stored inside fall into the water together with the case 18, and the case 18 automatically breaks and the decomposition catalyst 18 inside is dispersed in the water together with sodium percarbonate 17, and the reaction begins.

This reaction follows the sequence in which sodium percarbonate dissolved in water is first dissociated by water into sodium carbonate and hydrogen peroxide, and of which hydrogen peroxide is decomposed into water and oxygen by the decomposition catalyst 1B.

When closing the lid body 2, it is necessary to push down the locking part 6 of the locking lever 7 until it fits into the four parts 1a of the case body l and engages with the engaging part 1b. When the lever 5 and the engaging portion 1b are engaged, the tops of the first reaction tank 8, reserve tank 9, and humidification tank 10 are simultaneously sealed by the seat backing 3. In addition, if the capsule storage case 16 and the water injection hole 15 facing each other are sealed at the same time by the fitting protrusion 4 and the seal protrusion 5, the oxygen inside the case body l will not escape from these parts to the outside. No. However, if the backing sheet 3 seals the top of the reaction tank 8 more completely, the sealing by the protrusion 4 and seal protrusion 5 may be omitted.

Thus, the oxygen generated in one reaction tank 8 is transferred to the communication hole 11.
is fed into the reserve tank 9 through the communication hole 1.
2, and reaches the inside of the humidification tank 10 via the communication pipe 13,
It passes through the water and reaches the inhalation mask 22 via the inhalation pipe 21 from the outlet 2o. Therefore, this inhalation mask 22 is pressed against the face and fixed with a tightening band 23 if necessary, and oxygen inhalation is performed.

In addition, in case of an emergency, in order to save as much time as possible, the cartridge 14 is fitted into the reaction tank 8 in advance, and water is poured into the reaction tank 8 and the humidifying tank 10. It would be better to use a usage method in which a filling is placed between the lid 2 and the case body 1 so as not to close, and when necessary, the filling is removed and the lid 2 is closed.

Even if the internal pressure in the reaction tank 8 increases due to the bumping phenomenon during the reaction, it is safe because the pressure escapes into the reserve tank 9, and if the reserve tank 9 is enclosed around the outer periphery of the reaction tank 8. This has the advantage that even if the reaction tank is destroyed by an explosion, it is safe because there is a spare tank 9 outside it.

Next, the connecting hole! Even if the reaction liquid in the reaction tank 8 overflows through the humidifying tank 1, it collects in the reserve tank 9 and is transferred to the humidifying tank 1.
Since it does not reach within 0, there is no need to worry about contaminating it, making it safe and sanitary.

For example, if a diaphragm 34 made of tetrafluoroethylene (trade name: Microtex) is attached to the outlet 22 to allow only gas to pass but not liquid, water vapor can become water droplets and be sent toward the inhalation mask. This has the advantage of being more hygienic.

Note that the reserve tank may be provided adjacent to one side of the reaction tank, and there is no particular limitation on its installation location, but the advantages of installing it around the outer periphery of the reaction tank are as described above. In addition to manganese dioxide, Fe, C
It may be composed of u, Go, Cr, Pb, V, W, or one or more compounds selected from these compounds, but when these are directly contacted with a solution of sodium percarbonate, one reaction occurs. These decomposition catalysts are dangerous because they proceed explosively, and the reaction ends in an extremely short period of time, making them useless. The method is such that it is hardened with water and gradually melts over the course of an hour.

Further, the sodium percarbonate may be replaced with a known peroxide compound such as hydrogen peroxide or urea peroxide, and it goes without saying that the decomposition catalyst may be used in a liquid state from the beginning.

In short, various known oxygen generation methods may be tried.

As explained in detail below, according to this invention, safety and hygiene are improved, so it can be used not only in emergencies, but also in emergency situations.
It is possible to increase the chances of easily inhaling oxygen even in normal times, to relieve an oxygen deficiency state in an emergency, and to greatly contribute to improving health.
