Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an oxygen supply device that supplies an abundant amount of oxygen to the body for breathing assistance and recovery from fatigue immediately after sports or the like.

(Prior Art) Immediately after engaging in strenuous sports such as tennis, marathons, aerobics, and mountain climbing, the body tends to lack oxygen. Therefore, an example of an oxygen supply device that can easily replenish oxygen into the body for respiratory support and fatigue recovery was published in Japanese Patent Application Laid-Open No. 61-2229.
This is shown in Publication No. 06 and the like. In this method, sodium percarbonate, manganese monoxide, and water are separated and housed in a container by a partition wall, and when oxygen is generated, the partition wall is destroyed and the chemicals are mixed and reacted to chemically generate oxygen. It is designed to occur.

Another example of an oxygen supply device is one in which a low-pressure container is compressed and filled with pure oxygen, and the compressed oxygen is gradually discharged to supply oxygen.

(Problems to be Solved by the Invention) By the way, as described in JP-A-61-16724, inhaling oxygen at a concentration close to 100% into the body for a long time can cause pneumonia symptoms, neurological disorders, etc. It is known that it improves health. Therefore, when oxygen is used medically, pure oxygen is mixed and diluted with air and used at an oxygen concentration of 50% or less.

Therefore, in both the oxygen supply device disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 61-222906 and the oxygen supply device in which a low-pressure container is filled with oxygen, pure oxygen generated or discharged is diluted by mixing with air. An inhalation mask or mouthpiece, etc., through which pure oxygen is released into the body so as to be inhaled into the body, has a vent or an air introduction port that communicates with the outside air.

However, the mixing ratio of released pure oxygen and air varies greatly depending on the suction force and frequency of exhalation of the inhaler.
The desired dilution rate cannot always be obtained. In other words, if the suction force of the inhaler's exhaled air is weak and infrequent, the inside of the inhaler mask or mouthpiece is likely to be filled with released pure oxygen, and the amount of air introduced from the outside air is also small, resulting in a high concentration of oxygen. You will have to inhale oxygen. In addition, if the suction force of the inhaler's exhaled air is strong and frequent, a predetermined amount of pure oxygen is released into the inhaler mask or mouthpiece and is inhaled by the inhaler and introduced from the outside air. The amount of air is also large, and only a low concentration of oxygen can be inhaled.

The present invention was made in view of the above circumstances, and
An object of the present invention is to provide an oxygen supply device that discharges oxygen mixed and diluted with air to a desired concentration.

(Means for Solving the Problems) In order to achieve the above object, the oxygen supply device of the present invention has a turbo blower disposed at one end inside the main body case, and a turbo blower facing the discharge side of the turbo blower. A discharge port is opened in the outer circumferential wall of the main body case, and an intake [1 is opened on the outer circumferential wall of the main body case toward the other end side of the turbo blower,
An oxygen generator is removably attached to the other end side of the navigation body case, and a communication path is provided between the oxygen discharge port of the installed oxygen generator and the intake port to the intake port of the turbo blower. It is configured in a connected manner.

Furthermore, a shutter for adjusting the ventilation area may be provided at the intake port.

(Operation) Pure oxygen discharged from the oxygen generator and air from the intake port are sucked in by the turbo blower, mixed together, and discharged as oxygen at a predetermined concentration from the discharge port.

Furthermore, if a shutter for adjusting the ventilation area is provided at the intake port, the amount of air sucked from the intake air L] can be changed by adjustment by the shutter, and the concentration of oxygen discharged from the discharge port can be adjusted.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a longitudinal sectional view of one embodiment of the oxygen supply device of the present invention, FIG. 2 is an external perspective view of the oxygen supply device and chemical oxygen generator of FIG. 1, and FIG. (A),
(B) and (C) are partial longitudinal cross-sectional views showing the states of the shutter in "half open", "fully closed", and r fully open, respectively.

In the figure, a main body case 1 is made of resin, and a head portion 1a at the upper end is integrally formed with a body portion 1e at the lower end via a narrow neck portion 1b. This main body case 1 is large enough to be held with one hand. A motor 2 is fixed in the head 1a of the main body case 1 with its rotating shaft protruding downward, and a turbo-type blower, for example, a centrifugal fan 3 is disposed on the rotating shaft of the motor 2. . Further, a discharge outlet 4 is opened in the outer peripheral wall of the head 1a facing the discharge side of the centrifugal fan 3. Furthermore, a control switch 5 for switching the rotational drive of the motor 2 between "high speed", "low speed", and "stop" is provided on the head 1a. Note that 5a is an operation knob of the control switch 5.

Also, the torso 1. An opening 6 is provided at the lower end surface of the main body case 1, through which a chemical oxygen generator 7 can be inserted into the JH section lo, and is detachably attached to the main body case 1. This chemical oxygen generator 7 has a convex portion 7a protruding from its outer circumference, which engages with four parts provided on the inner circumferential wall of the opening 6 when it is attached, and the attached condition is stably maintained by a click action. . Also,
An intake port 8 is opened in the outer peripheral wall of the body IC, and a shutter 9 is movably disposed in the intake port 8. The intake port 8 has a plurality of elongated holes 8. ．． 8a- are bored at equal intervals with the opening width and non-opening width being the same. Further, the shutter 9 also has elongated holes 8a, 8. Elongated holes 9a, 9a-... are bored at the same intervals and the same width as... Furthermore, a control knob 9b is provided protruding from the shutter 9 so that it can be operated from the outside of the main body case 1. Then, as shown in FIG. 3(A), the long hole 81.8□ of the intake port 8 is opened by a click mechanism or the like.
..., the long hole 9m of the shutter 9, 9. -- is in a half-open state, and as shown in FIG.
1, 9, etc. do not overlap at all, and a "fully closed" state where the holes 8a, 8. - and the long hole 9 of the shutter 9. ．． 9. - is switched to the "fully open" state where all the marks overlap.

Further, this intake port 8 and the oxygen discharge lower b of the chemical oxygen generator 7 are communicated with the intake port of the centrifugal fan 3 via the neck portion 1b by a communication path IO. Further, a battery 11 for supplying power to the motor 2 via the control switch 5 is housed in the body portion 1e so as to be easily replaceable.

Here, the chemical oxygen generator 7 will be briefly explained. For example, granular sodium percarbonate as a hydrogen peroxide derivative and manganese dioxide as a decomposition catalyst sealed in a water-soluble paper bag are stored in a resin container. A water injection hole 7c is provided in the container, and is normally closed with a stopper 7d. Further, a breathable and water-impermeable membrane 7e is disposed to cover the oxygen discharge lower b. The chemical oxygen generator 7 has such a configuration, and when generating oxygen, a predetermined amount of water is poured into the container through the injection hole 7c. Then, the water-soluble paper bag containing manganese dioxide dissolves, and the manganese dioxide and sodium percarbonate react in the water, producing oxygen.

In this configuration, when replenishing oxygen that is insufficient in the body, water is poured into the chemical oxygen generator 7 and the chemical oxygen generator 7 is attached to the main body case 1. Then, the shutter 9 is set to "half open" and the control switch 5 is set to "low speed". Then, the oxygen generated by the chemical oxygen generator 7 and the air from the intake port 8 are sucked by the centrifugal fan 3, mixed, and the mixed and diluted oxygen is discharged from the discharge port 4. Here, the amount of air sucked through the intake port 8 is approximately constant depending on the ventilation area of the intake port 8 and the suction force of the centrifugal fan 3.

Further, the amount of oxygen generated from the chemical oxygen generator 7 can be considered to be approximately constant. Therefore, the oxygen discharged from the discharge port 4 is diluted to a predetermined concentration. Moreover, if the shutter 9 is set to the "fully open" state, the concentration of oxygen discharged from the discharge port 4 can be further reduced. Furthermore, if the shutter 9 is in the "fully closed" state, the discharge port 4
It is also possible to exhale pure oxygen that has not been diluted with air. If the chemical oxygen generator 7 is not injected with water and no oxygen is generated, the shutter 9 is set to "fully open", and the control switch 5 is set to "high speed", it can be used as a portable electric fan.

Note that the oxygen generator is not limited to the chemical oxygen generator 7 as in the above embodiment, but may be a low-pressure container compressed and filled with pure oxygen. The chemical oxygen generator 7 is not limited to the structure of the above embodiment, but may have any structure as long as it can chemically generate oxygen appropriately.

Further, instead of the centrifugal fan 3, an axial fan, mixed flow fan, or cross-flow fan may be used as the turbo blower. Further, the shutter 9 can be set to "half open", "fully closed", "-
The ventilation area of the intake air 118 is not limited to the three states of "fully open", but may be one in which the ventilation area of the intake air 118 can be adjusted steplessly. And furthermore,
The power source for the motor 2 is not limited to the battery 11 housed in the main body case l, but may also be a commercial AC power source that is suitably transformed and rectified.

(Effects of the Invention) Since the present invention is configured as described above, it achieves the following particularly excellent effects.

The air from the intake port and the oxygen generated by the oxygen generator are
Both are sucked in by a turbo blower, mixed together, and then discharged from a discharge port. The amount of air sucked from the intake port is approximately constant depending on the ventilation area of the intake air [:1] and the suction force of the turbo blower, and oxygen diluted to a substantially predetermined concentration is discharged from the discharge port. For this reason, oxygen can be easily replenished without causing any harm to health. Further, since the oxygen diluted with air is discharged as cool air by the turbo blower, a refreshing feeling can be obtained, which is useful immediately after sports.

Furthermore, if a shutter for adjusting the ventilation area is provided at the intake port to adjust the ventilation area, the dilution rate of oxygen can be adjusted as appropriate.
