Description

  The present invention relates to an oxygen generator used for inhaling oxygen for health promotion, recovery from fatigue after exercise, recovery of illness, and the like. The present invention relates to a nozzle ejected from a nozzle and a cartridge for the oxygen generator.

  An oxygen generation method in which a metal catalyst (hereinafter simply referred to as a catalyst) is allowed to act on a hydrogen peroxide solution (including a hydrogen peroxide adduct, the same in this specification) to generate oxygen is a peroxidation method. Hydrogen water does not fall under the category of dangerous goods under the Fire Service Law, and does not fall under the scope of regulation under the Poisonous and Deleterious Substances Control Law, and with an oxygen generator and catalyst, it has the great advantage that oxygen can be easily generated and sucked. For this reason, various oxygen generators have been proposed in which a catalyst is allowed to act on a hydrogen peroxide solution in a sealed reaction chamber to eject oxygen from a nozzle.

Such oxygen generators are disclosed in Patent Document 1 and Patent Document 2.
JP-A-8-253302 JP 2000-325789 A

However, in any of the above oxygen generators, hydrogen peroxide water is directly filled into the oxygen generator body, the catalyst is injected into the oxygen generator body in an unrestrained state, and both are brought into contact with each other. By closing the top lid on the generator body, oxygen is discharged from the oxygen discharge port.
Therefore, it takes some time until the lid is sealed after the catalyst is brought into contact with the hydrogen peroxide solution. Therefore, there is a problem that oxygen generated during the diffusion is diffused and the effective utilization rate is lowered. Moreover, there is a risk that the hydrogen peroxide solution and the catalyst may flow out to the surroundings by overturning the oxygen generator if it is sealed quickly. Furthermore, every time one oxygen generation reaction is completed, water generated by the reaction and the remaining catalyst are discharged from the oxygen generator main body and disposed, which is complicated and troublesome.

In view of this point, the oxygen generator is divided into a main body and a cartridge that can be attached to and detached from the main body, and the cartridge is separately provided with hydrogen peroxide and a colloidal catalyst, and the bottom of the main body is broken. An oxygen generator is provided that is configured to break a bag or the like containing a catalyst with a breaking member when the cartridge is connected to the bottom of the main body and inject the catalyst into hydrogen peroxide water when the cartridge is connected to the bottom of the main body. References 3, 4 and 5 disclose this.

However, in these prior arts, the catalyst is injected and mixed into the hydrogen peroxide solution every time an oxygen generation reaction is performed, and after the reaction is completed, the catalyst exists in a restrained state in the water. At the time of disposal, there is a problem that the catalyst affects the environment. And since the catalyst is expensive and can be used repeatedly, it is desirable to collect and recycle it. However, since it is mixed with the water in the cartridge, the oxygen generator user must collect the catalyst. Is practically impossible, and the problem of environmental destruction caused by discarded catalyst has not been solved. Furthermore, since recycling use of the catalyst has not been realized, it has been an impediment to reducing the oxygen suction cost.
For this reason, there has been a long-awaited appearance of an oxygen generator that can be used safely and safely at low cost, without the problem of environmental destruction caused by disposal.

  The present invention has been made to meet the above-described long-awaited needs. That is, the first object of the present invention is to provide an oxygen generator that can handle oxygen at a low cost without causing troublesome handling of hydrogen peroxide solution and catalyst, and without causing a problem of environmental influence of the catalyst. There is to do. The second problem is to provide an oxygen generator in which the catalyst is used uniformly and highly efficiently and the amount of oxygen generated is increased. The third problem is to prevent the hydrogen peroxide solution from being ejected together with oxygen even if it is accidentally knocked down during use. The fourth problem is to prevent the unreacted hydrogen peroxide solution from being mixed into the oxygen ejected from the nozzle. A fifth problem is to provide the above-described oxygen generator cartridge suitable for solving the first and second problems.

In order to solve the first problem, an oxygen generator according to the present invention has a cartridge housing space that is open on the upper surface and that can be exchangeably accommodated with a cartridge sealed with hydrogen peroxide water. A main body, a lid portion that is detachably coupled to the main body so as to seal the opening surface of the cartridge housing space, and a bottom surface of the lid portion, and the lid portion is coupled to the main body. The hydrogen peroxide is provided on the upper side of the edge of the seal breakage portion, the seal breakage portion opening the seal of the cartridge accommodated in the cartridge accommodation space, and the hydrogen peroxide A catalyst holding part for holding a catalyst that enters and contacts water to generate oxygen gas, and the lid part is generated by the reaction of the hydrogen peroxide solution and the catalyst. Nozzles for ejecting containing gas is characterized by being provided (claim 1).
With the above configuration, with the cartridge containing the hydrogen peroxide solution sealed in the main body, holding the lid and breaking the cartridge seal at the seal breaking portion, the catalyst holding portion is placed in the hydrogen peroxide solution. When the cover is attached to the main body and the opening surface of the main body is sealed, the hydrogen peroxide solution comes into contact with the catalyst, and oxygen gas is generated by the reaction and ejected from the nozzle. When the generation of oxygen is completed, water produced as a by-product during the generation of oxygen remains in the cartridge in addition to the solvent water. After separating the lid from the body, the cartridge can be removed and the water discarded. The catalyst is held in the catalyst holding unit.

It is desirable that the catalyst holding part is made of a net and contains a granular or massive catalyst therein (claim 2).
By making the catalyst holding part made of a net and holding the granular or massive catalyst therein, the contact efficiency between the catalyst and the hydrogen peroxide solution is increased.

Preferably, the catalyst holding part is configured to detachably hold a plurality of mesh cases holding the catalyst discretely in a case holding part provided above the seal breaking part. .
By using a plurality of net cases, the catalytic reaction between the catalyst and the hydrogen peroxide solution is promoted. Further, when the catalyst loses its effectiveness, the net case can be replaced.

It is desirable that the net case is formed by abutting the openings of two shells each having a large number of slits and joining them in a snap manner, and holding the granular catalyst in alignment with each of the slits ( Claim 4).
Since the granular catalyst is aligned in the slit, all the catalysts uniformly contact and react with the hydrogen peroxide solution.

The oxygen generator according to claim 3 or 4 includes an upper member in which the seal rupture portion is detachably coupled to the lid portion, and a lower member having an edge formed at the lower end portion so as to easily break the seal. A screw shaft is formed on one of the upper member and the lower member, and a screw hole is formed on the other of the upper member and the lower member. A lower holding portion having a groove extending radially upward on the member and opening upward, and an upper holding portion having a groove extending radially from the central hole corresponding to each groove of the lower member of the fracture portion and opening downward The upper holding portion is fixed at the same time as the upper member and the lower member are joined by passing through the screw shaft into the central hole and screwing into the screw hole, and the upper holding portion and the lower portion Opposing grooves in the holding part Network Case made catalyst retention can be configured to be fixed in (Claim 5).
With the above configuration, even if the lower member and the upper member of the seal breaking portion are not separated, if the two members are relatively rotated, the upper holding portion and the lower holding portion of the case holding portion are separated, so that they are held therebetween. The catalyst holding net case can be replaced and fixed again.

In order to solve the third problem, an oxygen generator according to the present invention has a serrated edge in which a seal rupture portion is provided radially along a conical surface having a tip at a lower end portion of a straight pipe, A holding part is provided on the outer surface of the straight pipe above the edge, and extends from the axis of the straight pipe toward the inner wall surface of the main body above the catalyst holding part, and the oxygen generator rolls over. In this case, an oxygen suction pipe having a suction port located above the water surface of the hydrogen peroxide solution is provided, and the straight pipe is provided with a weight on the opposite side of the oxygen suction pipe with respect to the axis. The upper end portion of the straight pipe is connected to a connecting portion fixed to the bottom surface of the lid portion so as to be rotatable about the axis of the straight pipe (Claim 6).
With the above configuration, when the oxygen generator rolls over, the fracture portion and the catalyst holding portion rotate around the axis of the straight pipe so that the weight is positioned vertically downward due to the moment of the weight, and the suction port of the oxygen suction pipe is Always above the waterline of the hydrogen peroxide solution.

  It is desirable that the oxygen suction pipe and the weight are provided in the upper part of the straight pipe (claim 7).

One end of the broken portion and the catalyst holding portion of the oxygen generator communicates with the suction port of the oxygen suction pipe, passes through the oxygen suction pipe from the suction port, and is folded back at the lower portion of the straight pipe. It is desirable to provide an oxygen induction tube extending from the bottom surface of the lid portion to the inside of the lid portion through the upper end portion of the tube.
With the above configuration, oxygen generated in the cartridge enters the oxygen induction tube from the suction port of the oxygen suction pipe, passes through the oxygen suction pipe, makes a U-turn near the lower portion of the straight pipe, and at the upper end of the straight pipe. Since it is guided into the connecting portion of the lid, oxygen gas is sent to the lid without being mixed with hydrogen peroxide.

It is preferable that the weight is held by a weight holding portion having a lower surface and an upper surface that are continuously inclined or arcuate on a side surface, and a saw-toothed edge is formed on the lower surface and the upper surface of the weight holding portion. Item 9).
If the lower and upper surfaces of the weight holding part are continuously sloped or arcuate on the side surfaces and serrated edges are formed on the lower and upper surfaces, the weight of the weight after the seal breakage part breaks the cartridge seal and enters. When the seal reaches the seal, the seal is easily broken.

In the invention of claim 6, the catalyst holding part, the edge of the seal breaking part, the straight pipe, the oxygen suction pipe and the connecting part are integrally configured as a unit, and the connecting part is attached / detached on the bottom surface of the lid part. It is desirable to be connected freely (claim 10).
With the above configuration, the catalyst holding part, the seal breaking part, the straight pipe, the oxygen suction pipe and the connecting part are detachably connected to the bottom wall of the lid part as a single component.

The above oxygen generator is provided with a secondary catalyst holding part in the lid part, and unreacted hydrogen peroxide contained in oxygen supplied from the main body into the lid part is held in the secondary catalyst holding part. It is desirable to contact with the catalyst (claim 11).
When the secondary catalyst holding part is provided in the nozzle, the unreacted hydrogen peroxide contained in the oxygen is brought into contact with the catalyst again before the oxygen supplied from the main body into the lid part is released from the nozzle. It is done.

Further, when the secondary catalyst holding part is provided, a water storage chamber for receiving water discharged from the secondary catalyst holding part is integrally provided in the nozzle, and the nozzle with the water storage chamber is detachably coupled to the lid part. (Claim 12).
With the above configuration, water generated when the unreacted hydrogen peroxide solution reacts with the secondary catalyst is stored in the water storage chamber.

The oxygen generator 4 according to claim 1 or 12 is provided with an oxygen gas cleaning portion that can be seen through from the outside between the bottom wall of the lid portion and the nozzle or the secondary catalyst holding portion, and is transparent to the oxygen gas cleaning portion. It is desirable that the cleaning liquid is filled (claim 13).
With the above configuration, the oxygen gas generated in the cartridge is purified when entering the oxygen gas cleaning section of the lid, and the cleaned state can be seen.

The oxygen generator cartridge according to the present invention, which is exchangeably housed and fixed in the oxygen generator main body, has a bottomed cylindrical body having an upper surface opening, in which hydrogen peroxide water is sealed, The opening is hermetically sealed with a seal that can be broken by a seal breaking portion of the oxygen generator (claim 14).
By the said structure, it can attach or detach easily to a main body. By holding the lid portion, the edge of the seal breaking portion is pushed into the seal to be broken, and the upper surface of the cartridge can be sealed with the lid portion as it is.

The cartridge seal is preferably made of a film that is not permeable to hydrogen peroxide and permeable to oxygen.
When sealed with this film, a small amount of oxygen generated inside during storage of unused cartridges escapes from the seal.

  According to the first aspect of the present invention, when a new cartridge is accommodated in the main body of the oxygen generator, the seal of the cartridge is broken at the broken portion of the lid, and the lid is fitted and fixed to the main body as it is. Oxygen is ejected from the tank, so that troublesome work at the start of use is unnecessary, and it is possible to cope with the case where quick oxygen inhalation is required. Also, after the generation of oxygen is completed, the catalyst is also removed when the lid is removed, so the cartridge in the main body can be easily removed and the water in it can be easily discarded. Then, oxygen can be generated again. Moreover, since the catalyst is held in the catalyst holding part, it can be recycled without any trouble. Therefore, simple and low-cost oxygen inhalation is possible.

  According to the second aspect of the present invention, the contact efficiency between the catalyst and the hydrogen peroxide solution is increased by making the catalyst holding portion made of a mesh, which can contribute to stable and reliable oxygen generation.

  According to the invention of claim 3, by using a plurality of net cases, the reaction between the catalyst and the hydrogen peroxide solution is promoted, the oxygen generation rate can be increased, and the catalyst loses its effectiveness. If this happens, oxygen can be inhaled quickly by replacing the case.

  According to the invention of claim 4, the mesh case is formed by abutting the openings of two shells each having a large number of slits and joining them in a snap-type manner. Reacts with the hydrogen peroxide solution evenly and uniformly, so that oxygen is generated with very high efficiency, and the oxygen generation amount or generation time as calculated can be obtained. Further, since the case can be opened and closed in a snap manner, the catalyst that has lost its effectiveness can be discarded and a new catalyst can be loaded.

  According to the invention of claim 5, the seal breaking portion is divided into an upper member that is detachably coupled to the lid portion and a lower member having an edge at the lower end portion. One of the upper member and the lower member is formed with a screw shaft, and the other is formed with a screw hole into which the screw shaft can be screwed and coupled. The case holding portion projects radially downward from the lower member of the seal rupture portion and has an upward opening groove, and extends downward from the center hole corresponding to each groove of the lower member of the seal rupture portion. And an upper holding portion having an opening groove. The upper holding portion is fixed to the upper holding portion and the lower holding portion at the same time as the upper holding portion and the lower holding portion are coupled to each other by connecting the upper member and the lower member by passing through the screw shaft into the central hole and screwing into the screw hole. A mesh case for holding the catalyst is fixed inside. Therefore, even if the lower member and the upper member are not separated, the two members are relatively rotated to separate the upper holding portion and the lower holding portion of the case holding portion, and the catalyst holding net held between them is made. The case can be easily replaced and fixed.

  According to the invention of claim 6, when the oxygen generator rolls over, the straight pipe having the catalyst holding portion of the seal breaking portion and the seal breaking edge is positioned so that the weight is positioned vertically downward by the moment of the weight. Since it rotates around, the inlet of the oxygen inlet pipe is always located above the surface of the hydrogen peroxide solution. Therefore, even if the roll is turned over, the hydrogen peroxide solution does not blow out from the nozzle.

  According to the seventh aspect of the present invention, since the oxygen suction pipe and the weight are provided on the upper part of the straight pipe, it is easy to integrally form them, and the production cost can be reduced. Separation of hydrogen peroxide solution and oxygen gas is performed in both the normal posture and rollover.

  According to the invention of claim 8, the oxygen induction tube passes through the oxygen suction pipe from the tip of the oxygen suction pipe, makes a U-turn at the lower part of the straight pipe, passes through the upper end of the straight pipe, and from the bottom surface of the lid. Since it extends to the inside of the lid portion, oxygen generated in the cartridge can be sent to the lid portion without mixing hydrogen peroxide water therein. In addition, since there is room in the length of the oxygen induction tube, even if the straight tube rotates as it rolls over and the oxygen induction tube is twisted, the restoring force of the tube acts in the opposite direction to the twist, and the twist Since it is returned, there is no fear of being blocked.

  According to the ninth aspect of the present invention, the lower surface and the upper surface of the weight are continuous with the side surface in an arc shape or inclined shape, and have a saw-toothed edge. It can enter smoothly to the required position inside. In addition, when the lid portion is separated from the main body, the weight shoulder portion can be smoothly escaped without being locked by the seal.

  According to the invention of claim 10, since the catalyst holding part, the seal breaking part, the straight pipe, the oxygen suction pipe and the connecting part are integrally provided in the unit, the seal breaking part and the catalyst holding part are attached to the lid part. It is easy to replenish and replace the catalyst or replace the worn seal rupture part.

  According to the invention of claim 11, since the oxygen gas supplied into the lid is brought into contact with the catalyst again in the secondary catalyst holding unit, the oxygen gas contains unreacted hydrogen peroxide solution. Also, when passing through the secondary catalyst holding part, it is completely changed to oxygen and ejected from the nozzle. Therefore, harmful unreacted hydrogen peroxide solution is prevented from being ejected from the nozzle.

  According to the twelfth aspect of the invention, the water generated when the unreacted hydrogen peroxide solution reacts with the secondary catalyst in the secondary catalyst holding part is stored in the water storage chamber without being discharged from the nozzle. Therefore, the indoor humidity does not increase unnecessarily during use of the oxygen generator, and water drops do not fall into the room. During the generation of oxygen, the generated water can be stored in the water storage chamber, and when no oxygen is generated, the nozzle can be removed from the lid and discarded.

  According to the invention of claim 13, since oxygen supplied from the main body to the lid portion can be seen to pass through the cleaning liquid of the oxygen gas cleaning section that can be seen through from the outside, whether or not oxygen is supplied to the nozzle. Can be easily confirmed. And since oxygen can be visually observed, it gives the user a sense of security and reliability.

  According to the fourteenth aspect of the present invention, the oxygen generator cartridge has a bottomed cylindrical body having an upper surface opening, in which hydrogen peroxide is enclosed, and the upper surface opening is broken by the seal breakage portion of the oxygen generator. It is convenient for safe handling of hydrogen peroxide solution, which is a raw material, and can be easily attached to and detached from the main body. Hold the lid and push the edge of the seal breakage part into the seal to open the breakage. Since the lid can be sealed as it is, oxygen can be generated with a minimum of labor.

  According to the fifteenth aspect of the present invention, the cartridge seal is made of a film that is not permeable to hydrogen peroxide solution and permeable to oxygen. Accidents such as rupture due to trace oxygen generated inside during storage can be prevented.

  Subsequently, the best mode of the present invention will be described with reference to the drawings.

  1 is a perspective view of an oxygen generator according to a first embodiment of the present invention, FIG. 2 is a longitudinal sectional view, and FIG. 3 is an exploded perspective view.

  The oxygen generator A according to the present invention includes a main body 100, a lid portion 200 that is detachably coupled to the upper portion of the main body 100, a seal breaking portion 300 that projects downward from the bottom surface of the lid portion, And a catalyst holding part 400 provided at the seal breaking part.

  The main body 100 is formed in a bottomed cylindrical shape, has a cartridge housing space 101 that opens upward, and is coupled to the upper outer peripheral surface so as to be separable by fitting rotation or reverse rotation with the lower periphery of the lid portion 200 as an example. The coupling means 102 is provided. Preferably, a cartridge mounting portion 103 having a width of about several mm along the opening surface of the cartridge housing space 101 is formed on the periphery of the upper end portion of the main body 100.

  Then, the following cartridge 500 can be exchangeably accommodated in the cartridge accommodating space 101 from the opening on the upper surface. That is, the cartridge 500 is formed in a bottomed cylindrical shape having substantially the same shape as the cartridge housing space 101, and hydrogen peroxide solution H2 O2 is sealed therein, and the opening surface of the cartridge is sealed with a seal 501. (See FIG. 3). An outward flange 502 is formed on the same upper surface as the opening surface of the cartridge 500, and the periphery of the seal 501 is joined to the upper surface of the flange 502.

  Since the hydrogen peroxide solution generates a trace amount of oxygen even when it is not in contact with the catalyst, if it is completely sealed, the internal pressure of the cartridge becomes high and the seal 501 may be ruptured. In order to avoid such an inconvenience, a seal 501 that is not permeable to hydrogen peroxide solution and permeable to oxygen is used. For such a seal, a composite film obtained by laminating a non-woven fabric of PET with a microporous polyolefin diameter film, for example, “Excelpe” manufactured by Mitsubishi Plastics, Inc. can be used. This film has a pore size larger than water vapor (up to about 1 angstrom) and smaller than a water droplet (about 100 μm). The water pressure resistance is 160 kPa, and moisture does not permeate below this pressure. Therefore, even if hydrogen peroxide solution is constantly decomposed and oxygen gas is generated, it will permeate through this film and breathe, so the inside of the cartridge is always kept at the same level as the external pressure, so the film will swell and tear. There is nothing. Therefore, the safety of the cartridge being transported is guaranteed.

  The cartridge 500 having the above-described configuration can be perfectly stored in the cartridge storage space 101 of the main body 100, and the flange 502 is mounted on the cartridge mounting portion 103 and fixed.

  The lid part 200 has a lower peripheral wall 212 including a coupling means 211 that is detachably coupled to the coupling means 102 by fitting rotation or reverse rotation around the lower part of the upper outer peripheral wall 210 as an example on the upper part of the main body 100. Yes. A lower opening chamber 214 is formed at the center of the bottom surface of the bottom wall 213 of the lid portion 200, and a female connection portion 215 is formed around the lower portion of the chamber. As will be described later, oxygen gas generated in the cartridge is supplied to the chamber 214, and a filter 216 for removing water and other foreign matters that may be mixed with the oxygen gas is provided in the upper portion of the chamber 214. The oxygen that has passed through the filter is guided to the nozzle 230 via the air guide path 217 and the connecting pipe 218. Since the oxygen that has reached the nozzle 230 is pressurized, it can be ejected from the nozzle with a momentum that can reach the nostril of the oxygen generator user.

  A detachable unit U1 integrally provided with a seal rupture portion (hereinafter simply referred to as a rupture portion) 300 and a catalyst holding portion 400 is preferably detachably coupled to the female connection portion 215 of the lid portion 200. The detachable unit U1 has a shaft 301, and a cup-shaped male coupling portion 303 that can be detachably coupled to the female coupling portion 215 of the lid portion 200 by screwing is formed at an upper end portion thereof. A plurality of holes 303 penetrating in the vertical direction are provided at the bottom of the male connecting portion 303. Depending on the size and number of the holes 303, the pressure of oxygen generated in the cartridge 500 and gathered in the upper space is appropriately increased and discharged into the male connecting portion 303. Then, the oxygen gas generated in the cartridge 500 and discharged into the male connecting portion 303 flows into the female connecting portion 215. In the structure for coupling the detachable unit U1 and the lid part 200, the positional relationship between the male connecting part and the female connecting part may be reversed.

The breaking portion 300 has an edge (blade edge) 302 that can easily break the seal 501 when pushed down toward the seal 501 of the cartridge 500 at the lower end of the shaft 301.
The shaft 301 is provided with a catalyst holding unit 400 above the edge 302. The catalyst holding unit 400 is formed of a half-cut case made of a net that is open on one side and slits on the other side, and is detachably fitted to both side surfaces of the shaft 301. A granular or massive catalyst (not shown) is accommodated in the catalyst holding unit 400. Since the case is made of a net, when the catalyst holding unit 400 enters the hydrogen peroxide solution of the cartridge 500, the hydrogen peroxide solution flows through the catalyst holding unit 400 and comes into contact with the catalyst in the cartridge 500. Is used as a reaction chamber to generate oxygen.

  As the catalyst, a known metal catalyst that reacts with hydrogen peroxide solution to generate oxygen, for example, those described in JP 2000-325789 A and other publications can be used.

  In order to allow oxygen generated in the cartridge 500 to flow into the chamber 214 of the female connection part 215, a plurality of holes are formed in the side wall of the male connection part 303 of the breaking part 300 and the female connection part 215 of the lid part 200. However, these holes may be matched. In this case, it is possible to adjust the oxygen discharge speed or the pressure for ejecting oxygen from the nozzle 230 so as to reach the user's nostril according to the rotation angle of the fracture portion.

  When hydrogen peroxide reacts with the catalyst, it generates heat. In order to prevent burns even if the user grips the main body 100 of the oxygen generator main body during oxygen inhalation, is a heat insulating space provided between the main body 100 and the cartridge 500 accommodated therein? It is desirable to make the main body 100 with a heat insulating material.

  In order to generate oxygen using the oxygen generator A according to the first embodiment configured as described above, the lid portion 200 of the oxygen generator main body is separated from the main body 100 as shown in FIG. An unused cartridge 500 is accommodated in the opened cartridge accommodating space 101, and its flange 502 is placed and fixed on the cartridge placing portion 103 of the main body 100, and then the edge of the breaking portion 300 is held with the lid portion 200. 302 is pushed down toward the center of the seal 501 on the upper surface of the cartridge 500 to break the seal, and the lid part 200 is lowered as it is to fit the lower peripheral wall 212 of the lid part 200 to the upper peripheral part of the main body 100. And it rotates and it fixes by the coupling | bonding means 211,212 of the main body 100 with the cover part 200. FIG. During this time, the broken portion 300 and the catalyst holding portion 400 that have broken the seal 501 enter the hydrogen peroxide solution contained in the cartridge 500, so that the hydrogen peroxide solution contacts the catalyst held in the catalyst holding portion 400. As a result, oxygen is generated and gathers in the upper space of the cartridge 500, passes through the hole 301 in the upper portion of the fracture portion 300 into the female connection portion 215 of the lid portion 200, is purified by the filter 216, and then the nozzle The pressurized oxygen is ejected from 230.

To explain one specific example, the cartridge 500 has 170 cc of 6% hydrogen peroxide solution, and the catalyst held in the fracture portion 300 is platinum carried on an aluminum carrier or palladium carried on an aluminum carrier. Continuously generated at a rate of 0.5 to 0.6 liter / min for 5 minutes. The theoretical value of the total amount generated is 3.4 liters.
Depending on the amount of aqueous hydrogen peroxide used, the amount of catalyst, and the contact rate, the oxygen generation amount and duration can be variously changed. Moreover, it is possible to arbitrarily adjust the oxygen generation amount per unit time and the duration by adjusting the reaction rate of the catalyst with the support.

  Since the tip of the nozzle 230 opens slightly upward, the ejected oxygen travels toward the user's nostril, so that the user can inhale the oxygen easily and reliably.

  After the generation of oxygen is completed, if the lid 200 is not separated from the main body 100, water generated by the reaction is present in the cartridge inside, but the opening of the cartridge is sealed. There is no problem such as water leakage even if it is accidentally overturned. Further, if the lid 200 is separated from the main body 100 and the cartridge 500 inside is taken out, the water generated in the cartridge can be easily discarded. Furthermore, when the cartridge is replaced with a new cartridge, the next oxygen inhalation can be performed. Since the catalyst is always held by the lid, troublesome work such as catalyst replacement or recovery is unnecessary regardless of cartridge replacement. Further, since the catalyst can be recycled for a long period of time, it is possible to reduce the oxygen suction cost.

  The second embodiment shown in FIG. 4 and subsequent drawings is an oxygen generator B in which the structure of the detachable unit U2, particularly the catalyst holding unit 400, is improved. 4 is a longitudinal sectional view corresponding to FIG. 2, FIG. 5 is a perspective view showing only the detachable unit, FIG. 6 is an exploded perspective view, and FIG. 7 is an exploded perspective view of the case of the catalyst holding portion.

  The catalyst holding unit 400 according to the first embodiment has a limit in the amount of catalyst that can be held, and thus cannot increase the amount of oxygen generated per unit time. In addition, since the contact efficiency between the catalyst and the hydrogen peroxide solution is unstable, there is a concern that the amount of generated oxygen and the generation time are not always as calculated.

  The detachable unit U2 according to the second embodiment is configured by dividing the shaft 301 into an upper member 301a and a lower member 301b, as shown in FIG. The upper member 301a has a cup-shaped female connecting portion 303 at the upper end as in the case of the first embodiment, and a screw hole 304 that opens downward is formed at the center of the lower end. 305 is a reinforcing rib and 306 is a flange.

The lower member 301b has a cross section + -shaped edge 302 for breaking the seal of the cartridge 500 at the lower end, and a screw shaft 307 that can be screwed into the screw hole 304 of the upper member is provided at the upper end of the central axis. It has been. On the upper surface of each edge 302 and the side surface of the central axis, lower holding portions 308 formed by grooves 308a and 308b that are continuous in an L-shape are provided radially about the central axis.
Between the lower end portion of the upper member 301a and the upper end portion of the lower member 301b, a plane + character-shaped upper holding portion 309 is provided as follows. That is, the upper holding portion 309 has a groove (not shown) that opens to face the lateral groove 308a of the lower holding portion 308, and has a hole 310 through which the screw shaft 307 of the lower member can be inserted. ing. Thus, the screw shaft 307 is inserted into the screw hole 310 of the upper holding part and screwed into the screw hole 304 of the upper member 301a, whereby the upper member 301a and the lower member 301b are integrally coupled, and the upper holding part and the lower part The case holding part which consists of a groove | channel which continues in a U shape is comprised by the holding | maintenance part. Then, by rotating the upper member 301a and the lower member 301b in one direction relatively, the interval between the facing grooves of the case holding portion can be increased, and by rotating in the opposite direction, the interval between the grooves can be reduced. it can.

  Reference numeral 410 in FIGS. 4 to 7 denotes a catalyst holding case constituting the catalyst holding unit 400E1. As shown in an enlarged view in FIG. 7, this case is composed of a shell body 410 a that is open on one side and has a plurality of rows of slits 411 on the bottom surface, and another shell body 410 b that has similar slits 412. By fitting the locking projections 414 provided on the other into the locking grooves 413 provided on one side (410a), the openings can be closed or opened. The slits 411 and 412 in each row can be aligned with a granular catalyst (not shown) having the same size, and when the two shells 410a and 410b are joined in the aligned state, The catalysts are fixed with equal gaps between them.

  As described above, the case 410E holding the catalyst in this way rotates the lower member 301b around the axis in a predetermined direction to open the space between the upper and lower case holding portions 308 and 309, and opens one side of each case to the case. After being fitted into the vertical groove 308b of the holding portion 308, it is pushed down along the vertical groove 308b to be fitted into the horizontal groove 308a of the case holding portion 308 for stabilization, and then the case holding portion 309 is fixed to the screw shaft 307. The upper side of each case 410E is fitted into the lateral groove. In this state, when the upper member 301a is reversely rotated in a predetermined direction and the screw shaft 226 is securely screwed into the screw hole 223, the upper member 301a and the lower member 301b are firmly connected, and the case holding portion 309 is connected to the flange 306. Each case 410 is fixed by being clamped between the upper end of the case holding portion 308.

  Since the catalyst holding case 410E1 of this embodiment holds each of the catalysts in alignment with each slit, all the catalysts are in contact with the hydrogen peroxide solution in a uniform state when immersed in the hydrogen peroxide solution of the cartridge. Therefore, the reaction can be performed evenly. Therefore, the oxygen generator B of this embodiment can exhibit a theoretical oxygen generation amount and oxygen generation time. Therefore, when the waste is disposed after the predetermined endurance period, it is possible to prevent the occurrence of a problem of environmental destruction due to the disposal of the poison or the hazardous material due to the unreacted catalyst.

  Furthermore, since a plurality of catalyst holding cases are provided, the amount of oxygen generated by one reaction can be easily and arbitrarily increased according to the purpose of use by selecting the number of the catalyst holding cases. Since the catalyst holding case can be opened and closed in a snap manner, the catalyst can be easily replaced at home without being an expert.

FIG. 8 and subsequent drawings show a third embodiment of the present invention. 8 is a longitudinal sectional view of the oxygen generator, FIG. 9 is a side view of the detachable unit, FIG. 10 is a sectional view taken along the line XX of FIG. 9, FIG. 11 is a sectional view taken along the line YY of FIG. It is a bottom view of a part. If the oxygen generators A and B of Examples 1 and 2 are brought down during use, the hydrogen peroxide solution in the cartridge 500 may be ejected from the nozzle 230. In the third embodiment, the hydrogen peroxide solution is prevented from being ejected even if it is knocked down during use.
In this oxygen generator C, the detachable unit U3 connected to the lid part 200 includes a male coupling part 303 coupled to the female coupling part 215 of the lid part 200, and a straight pipe 311 extending downward from the coupling part. The attachment / detachment unit U3 is constituted by integrally including a catalyst holding portion 400E2 provided at the lower portion of the straight pipe, the edge 302 of the fracture portion, the oxygen suction pipe 312 and the weight 313. Similarly to the previous embodiment, 215 may be a male connecting portion and 303 may be a female connecting portion.

  The male connecting portion 303 is provided with a connecting pipe 314 that protrudes downward from the center of the bottom surface and communicates the inside of the male connecting portion 303 downward. The upper end portion of the straight pipe 311 is telescopically fitted to the connecting pipe 314, and the straight pipe 311 is formed by bearings 315 such as ball bearings provided at a plurality of axial positions on the upper part of the connecting pipe 314 or the straight pipe 311. It is connected so as to be rotatable about an axis.

  The straight pipe 311 is composed of a single straight pipe. A catalyst holding part 400E2 is provided outside the lower part. An edge 302 for breaking the seal is provided at the lower end. The catalyst holding portion 400E2 is formed with a flange 415 at an axially spaced position on the outer peripheral surface of the straight pipe, and a plurality of covers 416 divided in the outer peripheral direction of the straight pipe are attached adjacent to each other, and snap type And are connected so as to exhibit the appearance of one cylindrical body. Before completing the connection, a granular catalyst mc is accommodated in a chamber 417 formed between the straight pipe 311, the flange 415, and the cover 416.

  As shown in FIG. 12, the edge 302 provided at the tip of the detachable unit U3 is formed in a radial shape, for example, a cross shape, along a conical surface having a vertex at the axial center of the straight pipe 311. If the edge 302 is formed not only at the tip of the straight pipe 311 but also at the lower end surface of the catalyst holding portion 400E2, the seal 501 can be easily penetrated to the catalyst holding portion 400E2 when the seal 501 of the cartridge 500 is broken. Therefore, it is preferable. Further, as shown in FIG. 9, each edge 302 is desirably formed in a sawtooth shape in order to improve the sharpness of the cartridge 500 with respect to the seal 501.

  The oxygen suction pipe 312 has a base end connected to an upper portion of the straight pipe 311 than the catalyst holding portion 400E2, and extends obliquely upward toward the inner wall surface of the main body 100 in a state where the detachable unit is accommodated in the main body 100. , Has a suction port at its tip. The height of the suction port from the axis of the straight pipe 311 is such that when the oxygen generator C is rolled over during use, the suction port is located above the water surface of the hydrogen peroxide solution H2 O2 in the cartridge 500. It is designed to exit, i.e. the waterline is below the inlet.

  The weight 313 is accommodated in a weight holding portion 316 formed on the opposite side of the oxygen suction pipe 312 with respect to the axis of the straight pipe 311. Inclined surfaces or curved surfaces 316a and 316b are provided on the lower surface and the upper surface of the portion of the weight holding portion 316 that protrudes further away from the straight pipe 311 than the vertical upper extension line of the outer peripheral surface of the catalyst holding portion 400E2. . Thus, after the edge 302 of the breaking portion 300 breaks the seal 501 of the cartridge 500, the catalyst holding portion 400AE penetrates the seal and enters the cartridge, and then the weight holding portion 316 hits the seal and beyond. The weight holding portion 316 can be smoothly moved down to the weight holding portion without being prevented from entering, and when the lid 200 is separated from the main body 100 when oxygen is completely generated. The upper surface 316b can be smoothly escaped without being locked to the seal 501. The lower surface 316 and the upper surface 316b of the weight holding portion 316 may also be provided with serrated edges.

  Returning to FIG. 8, a filter 317 is attached to the suction port of the oxygen suction pipe 312. The oxygen that has passed through the filter is passed through the oxygen suction pipe 312, and passes through the straight pipe 311 to the vicinity of the lower end thereof. After being extended, it is folded back in the vicinity of the lower end portion thereof, is again extended upward in the straight pipe 311, and extended through the connecting pipe 314 and into the male side connecting section 303 by the oxygen induction tube 318. , And is guided into the chamber 214 of the female side connecting portion 215. When the airtightness of the passage from the tip of the oxygen suction pipe 312 to the male connector 303 is high, the use of such a tube is unnecessary, but in this embodiment having a rotating part, a high degree of airtightness is required. Manufacturing to have a cost increases. By using the tube 318, an increase in manufacturing cost can be avoided. In addition, when the tube is folded back to have a sufficient length, it is effective that the tube is closed and the outflow of oxygen gas is prevented even when the straight pipe 311 rotates around the connecting pipe 314. Can be prevented.

  With the above configuration, when the oxygen generator C is in use, the inlet of the oxygen inlet pipe 312 faces upward above the water surface of the hydrogen peroxide solution H2 O2, so that oxygen generated by reaction with the catalyst is generated. The gas is guided from the inlet through the tube 318 into the female connector 215, passes through the filter 216, and is discharged from the nozzle 230. And if the user accidentally knocks down during use, or if an infant or pet animal falls down, it will lie down side by side, depending on the direction of the nozzle until it stops after rotating in some cases. The weight 250 is quickly rotated around the axis of the straight pipe so that the weight 250 is always on the lower side due to gravity, and when the weight 313 is directly below, the rotation stops. When the weight is present directly below, the suction port of the oxygen suction pipe 312 faces directly above and exists above the upper surface of the hydrogen peroxide solution. Therefore, even if the oxygen generator C is brought down, the hydrogen peroxide solution is effectively prevented from being blown out from the nozzle 230 via the connecting portions 303 and 215.

  8 is a secondary catalyst holding unit provided in front of the nozzle 230. The secondary catalyst holding unit 600 is formed in a cylindrical shape, has an inlet 601 on the air guide path 217 side, has an outlet 602 on the nozzle 230 side, and is used in the catalyst holding unit 400E2. The same catalyst mc is accommodated. The outlet 602 is formed in a detachable lid 603. Accordingly, it is possible to remove the lid 603 and replace the catalyst mc inside. By placing the secondary catalyst holding unit 600 on the upstream side of the nozzle 230, when a small amount of unreacted hydrogen peroxide is mixed in the oxygen gas discharged from the air guide path 217, the hydrogen peroxide solution Since the oxygen reacts with the catalyst mc while passing through the secondary catalyst holding unit 600, it is effective that only oxygen gas is ejected from the nozzle 230 and oxygen mixed with hydrogen peroxide is ejected. To be prevented.

  When the unreacted hydrogen peroxide solution reacts with the catalyst to generate oxygen in the secondary catalyst holding unit 600, a small amount of water is also generated at the same time. Since this water is not discharged from the nozzle 230, a water storage chamber 700 for receiving the water is provided between the secondary catalyst holding unit 600 and the nozzle 230. The water storage chamber 700 is formed integrally with the nozzle 230, and the end of the water storage chamber 700 is detachably fitted to the end of the main body 210 of the lid portion 200 via the packing 701. Sometimes, the nozzle 230 with the water storage chamber is removed so that the water stored in the water storage chamber 700 can be discarded.

  The reason why the outlet 602 of the secondary catalyst holding unit 700 is biased from the axis of the nozzle 230 is to separate the trace amount of water flowing out from the outlet of the secondary catalyst holding unit 700 from the oxygen gas toward the nozzle 230 as much as possible. Because.

  The air guide path 217 in FIG. 8 and the inlet 601 of the secondary catalyst holding unit 600 may be connected by a connecting pipe 218 as shown in FIG. However, the connecting tube 218 is not provided, and the chamber formed between the bottom wall 213 of the lid part 200 and the main body 210 is filled with a cleaning liquid such as water and is included in the oxygen gas discharged from the air guide path 217. If the cleaning chamber 219 for removing impurities is provided, and a part of the main body 210 of the lid 200 is made transparent so that the inside of the cleaning chamber can be seen through, the oxygen gas is purified and is hygienic. Appeal to the user. Also, whether the user sees the bubbles moving in the window, whether or not oxygen is generated, without judging the presence or absence of wind pressure by bringing his face or hand close to the nozzle, It can be confirmed visually.
