(Embodiment 1)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

  1 to 10, an oxygen-enriching means (hereinafter, referred to as an “oxygen-enriched membrane unit”) such as an oxygen-enriched membrane unit that increases the concentration of oxygen and generates so-called oxygen-enriched air is provided inside the main body 1. 2) are provided. The oxygen-enriched membrane unit 2 is composed of a flat membrane made of an organic polymer, and utilizes the difference in the speed of molecules passing through the membrane. The so-called oxygen-enriched air is obtained. The ratio of oxygen in ordinary air is about 21% (about 79% of nitrogen), but in the oxygen-enriched air after passing through the oxygen-enriched membrane unit 2 of the present embodiment, the ratio of oxygen is about 30% (about 70% nitrogen).

  As shown in FIGS. 6 and 7, the oxygen-enriched membrane unit 2 includes a plurality of modules 5 each having a substantially rectangular oxygen-enriched membrane 4 attached to both sides of a frame 3 having a mesh structure and having a passage between both membranes. It has a substantially rectangular parallelepiped unit structure, in which a part of the air flowing around the oxygen-enriched film 4 passes through the oxygen-enriched film 4 by sucking the inside of the passage of the frame 3 to form the frame 3. After entering the passage, oxygen-enriched air is obtained, and the obtained oxygen-enriched air is exhausted from the unit outlet 6, which is the only outlet of the oxygen-enriched membrane unit 2. The substantially rectangular parallelepiped oxygen-enriched membrane unit 2 is configured such that the substantially rectangular oxygen-enriched membrane 4, which is a component of the unit, is arranged such that the short side is substantially parallel to the air traveling direction (the front-rear direction of the main body 1 in the present invention). The long side is provided in the main body 1 so as to be substantially perpendicular to the traveling direction of the air.

  Inside the main body 1, outside air is sucked into the main body 1 from an intake port 7 provided on the back surface of the main body 1, sent to the oxygen-enriched membrane unit 2, passed through the oxygen-enriched membrane 4, and It has a blower (hereinafter, referred to as a “fan”) 9 such as a motor fan for discharging outside air except for the air sucked into the passage from an exhaust port 8 provided on a side surface of the main body 1 to the outside. I have. The fan 9 is provided on the downstream side of the oxygen-enriched membrane unit 2 and near the exhaust port 8, and a circuit 70 is provided on the opposite side of the fan 9 from the oxygen-enriched membrane unit 2. It is attached so as to be in a direction parallel to the frame 3.

  Reference numeral 10 denotes a suction means such as a pump (hereinafter, referred to as a “pump”), which is provided below the oxygen-enriched membrane unit 2 in the main body 1 and has cooling fans 10 b at both ends of a rotating shaft. The air around the film forming unit 2 is sucked from the oxygen-enriched film 4 into the passage of the frame 3 and sent downstream. Further, the pump 10 sends the oxygen-enriched air that has passed through the oxygen-enriched membrane 4 to a discharge port 12 provided on the side surface of the main body 1 through a silencing pipe 11 on the downstream side. The air is supplied to the “oxygen-enriched air discharge means” described later, which is connected to the outlet 12. In addition, a bellows pump having a high operating pressure is used as the pump 10 in order to increase the flow rate of the oxygen-enriched air against the passage pressure loss of the oxygen-enriched membrane 4. The silencing pipe 11 is provided substantially horizontally near the pump 10 in the main body to reduce pulsation and noise of the oxygen-enriched air coming out of the pump 10 while making it difficult for water droplets to accumulate therein. The cross-sectional area of the passage of the pipe 11 is larger than the cross-sectional areas of the front and rear passage portions.

  Further, the pump 10 is mounted on a sheet metal 37 as shown in FIG. 4, and is fitted and attached to a bottom boss of the main body 1 via vibration isolating materials 38 and 39. It is fastened by a washer 40 and a screw 41 for preventing the boss from coming off. Further, the main body 1 is provided with legs 42 having an anti-vibration function on the bottom surface. A thermal fuse 43 for preventing overheating of the motor 10a, which is a driving source of the pump 10, is attached by a cushion 45 so as to urge the motor 10a in a direction of contact with the motor 10a.

  Reference numeral 14 denotes a handle of the main body 1, which is provided so as to be rotatable about a rotation shaft 15. Reference numerals 16 and 17 denote an inner case left and an inner case right, respectively, which constitute an inner case in which the oxygen-enriched membrane unit 2 and the pump 10 are built, and bearing portions which directly receive the rotary shaft portion 15 of the handle 14 above each of them. 18 and 19 are provided integrally. Reference numeral 20 denotes a holding portion for hooking and holding the "oxygen-enriched air discharging means" described later when not used, and its outer end is a large diameter portion. The holding portion 20 is provided integrally with the rotation shaft portion 15 of the handle 14, and does not need to be separately provided on the side surface of the main body 1, and does not hinder the rotation of the handle 14. Further, since it is provided integrally with the rotating shaft portion 15, the design of the appearance does not have a sense of incongruity and is good.

  As shown in the schematic configuration diagram of the main part of FIG. 10, a solenoid valve 60 for switching the introduction of outside air is provided in a path between the pump 10 in the main body 1 and the unit outlet 6 of the oxygen-enriched membrane unit 2. Before the end of the operation, the electromagnetic valve 60 was opened for about 1 minute to suck outside air that did not pass through the oxygen-enriched membrane 4 and sent to the downstream side by the pump 10 to perform a blowing operation, whereby the air stayed in the pipe or the like. When high humidity air is ventilated and water droplets are generated, it is driven out to a "liquid pool" to be described later, so that a path on the way is easy to dry. As shown in FIG. 10, an HEPA filter 61 is provided upstream of the electromagnetic valve 60 for switching outside air introduction. When introducing outside air, the HEPA filter 61 removes 0.3 micron particles. It is configured to remove 99.7%. Note that the air blowing operation is automatically executed after a normal operation by a timer is completed and after a stop state for a predetermined time (10 seconds in this embodiment). Similarly, when the off switch is operated to stop the normal operation by the timer halfway, the operation is similarly stopped after the air blowing operation.

  On the other hand, reference numeral 13 shown in FIG. 8 denotes a headset unit or the like for supplying the user with the oxygen-enriched air sent to the discharge port 12 formed by a curved pipe rotatably attached to the side surface of the main body 1. The headset unit 13 is an oxygen-enriched air discharge unit (hereinafter, referred to as a “headset unit”). The headset unit 13 has a discharge port 21 for a user to suck oxygen-enriched air. In the path between the discharge port 12 and the headset unit 13 provided on the side surface of the main body 1, a liquid pool 22 and a flexible material such as vinyl chloride for connecting the discharge port 12 and the liquid pool 22 are provided. A first connection pipe 23 made of a transparent tube, and a flexible second connection pipe 24 made of a transparent tube made of vinyl chloride or the like for connecting the liquid reservoir 22 and the headset unit 13 are provided. The first connecting pipe 23 and the second connecting pipe 24 contain an antibacterial agent or an antistatic agent or both of them, and are connected to each other by a liquid reservoir 22 in a detachable manner.

  The headset unit 13 includes an earpiece left 25, an earpiece right 26, a headband 27 connecting the earpiece left 25 and the earpiece right 26, and an oxygen-enriched air discharge port 21. And a flexible joint 29 which is detachably connected to the bottom surface 28 of the left ear support portion 26, connects the bottom surface 28 to the discharge port 21, and is provided so as to be freely bent. The second connecting pipe 24 having one end connected to the liquid reservoir 22 has the other end attached to and detached from the bottom surface 28 of the left ear contact portion 25 of the headset unit 13, similarly to the flexible joint portion 29. They are freely connected.

  The main body portion of the liquid pool 22 is separable into two parts 22a and 22b by a screw method or a press-fitting method while maintaining airtightness by an O-ring, and the main body part is separated into two parts and accumulated inside. It is provided to be able to discharge water drops and the like. At this time, in the screw method, separation and connection are enabled by twisting within one rotation. Further, a pipe portion A30 and a pipe portion protruding into the liquid reservoir 22 from a connection portion between the liquid reservoir 22 and the first connection tube 23 and a connection portion between the liquid reservoir 22 and the second connection tube 24, respectively. B31 is provided, and the pipe part A30 and the pipe part B31 are provided so that the center axes of the pipes are shifted from each other.

  On the other hand, as shown in FIG. 9, the discharge port 21 provided in the headset unit 13 is configured such that the discharge port main body 21a and the lid band 21b can be freely opened and closed by a spring latch or the like. A sterilizing filter 34 (hereinafter referred to as "biosterilizing filter") such as a biosterilizing filter impregnated with an enzyme is provided on the downstream side near the surface with a high collection efficiency filter such as a HEPA filter of an antibacterial material amenitop ( Hereinafter, it is referred to as “HEPA filter of antibacterial material amenitop”) 35. Further, a spherical body 46 impregnated with a fragrance is incorporated. Then, the bio-sterilization filter 34 suppresses the activity of the caught bacteria and the like, and further suppresses the activity of the virus. The antibacterial material amenitop HEPA filter 35 removes 99.7% of 0.3 micron particles and controls the activity of bacteria and mold collected by the action of the antibacterial material amenitop. The spherical body 46 adds scent to the discharge air.

  In addition, 32 shown in FIG. 5 is an operation switch provided on the top surface of the main body 1, and 33 is also provided on the top surface of the main body 1, and displays the operation time by the selected timer or the energized state of the blowing operation. It is a lamp. Reference numeral 50 denotes an LED which is provided on the front of the main body 1 and is lit and displayed only during normal operation (supply of so-called oxygen-enriched air having a high oxygen concentration).

  Next, the operation of the present embodiment based on the above configuration will be described.

  When the operation time (any one of 10 minutes, 20 minutes, and 30 minutes) is set by a timer (not shown) included in the circuit 70 and the operation switch 32 is operated, the pump 10 mounted via the vibration isolator is operated. The control means (not shown) for supplying operating power to the power supply operates, the lamp 33 indicating the energized state lights up, the pump 10 operates according to the time set by the timer, and the fan 9 operates. Then, by operating the fan 9, outside air is sucked from the intake port 7 provided in the main body 1, and this outside air passes through the oxygen-enriched membrane unit 2 and is discharged from the exhaust port 8 to the outside of the main body. On the other hand, when the outside air passing through the oxygen-enriched membrane unit 2 passes through the oxygen-enriched membrane unit 2, air is sucked into the frame 3 of the oxygen-enriched membrane unit 2 by operating the pump 10. It becomes enriched air. The oxygen-enriched air is sent to the discharge port 12 and is discharged from the discharge port 12.

  At this time, since the fan 9 is provided near the exhaust port 8, the inside of the main body 1 becomes a negative pressure due to the operation of the fan 9, the outside air is sucked from the intake port 7, and the space between the intake port 7 and the exhaust port 8 is formed. Since the gas flows around the oxygen-enriched membrane unit 2 provided in the main body 1, the oxygen-enriched membrane can be provided without providing an intake passage from the intake port 7 through the periphery of the oxygen-enriched membrane unit 2 to the exhaust port 8, particularly in the main body 1. It becomes possible to carry outside air to the periphery of the chemical conversion unit 2. Further, as shown in FIG. 5, if a hole 36 is provided around the outer periphery of the pump 10, the inside of the main body 1 becomes negative pressure due to the operation of the fan 9. The pump 10 can also cool the pump 10 around the hole 36 because of the entry. Further, the cooling of the pump can be enhanced by the fan 10b provided on the shaft of the pump 10.

  In the substantially rectangular parallelepiped oxygen-enriched film unit 2, the shorter side of the substantially rectangular oxygen-enriched film 4 as a constituent member is substantially parallel to the traveling direction of air (the front-back direction of the main body 1 in the present embodiment). And the long side of the substantially rectangular oxygen-enriched film 4 is provided in the main body 1 so as to be substantially perpendicular to the traveling direction of the air. Become. That is, assuming that the traveling direction of the air flow and the long side of the oxygen-enriched film 4 are provided substantially in parallel, the oxygen concentration of the air passing through the side surface of the oxygen-enriched film 4 increases along the flow of the air. The more forward, the smaller the number of oxygen molecules on the way because they pass through the oxygen-enriched film 4. Therefore, the efficiency with which oxygen molecules pass through the oxygen-enriched film 4 becomes worse as it goes forward, but in the present embodiment, the short side of the oxygen-enriched film 4 is directed in the direction of travel of the air (in the present embodiment, the main body 1). (In the front-rear direction), the efficiency with which oxygen molecules pass through the oxygen-enriched film 4 does not deteriorate.

  Further, since the oxygen-enriched air is discharged from only one outlet, which is the unit outlet 6 of the oxygen-enriched membrane unit 2, the connection with the downstream pump 10 is simplified. Since the oxygen-enriched membrane unit 2 is arranged on the pump 10, the main body is small in size, the installation area is small, and the configuration is highly stable. In addition, since the circuit 70 is mounted in a direction in which the substrate is parallel to the frame 3, the size of the entire circuit can be reduced while utilizing the cooling airflow from the fan 9.

  Further, since the pump 10 uses a bellows pump having a high pressure during operation in order to increase the flow rate of the oxygen-enriched air against the pressure drop through the oxygen-enriched membrane 4, the pulsation and vibration of the conveyed air are increased. The noise-reducing pipe 11 and the vibration-proof material effectively act on this. Since the muffling pipe 11 is arranged substantially horizontally near the pump 10, the temperature of the inside is small, and even when high-humidity air is passed, dew condensation hardly occurs and water drops hardly accumulate.

  Here, the oxygen-enriched film 4 has a higher oxygen permeation speed than the nitrogen permeation speed, and particularly, in the present embodiment, the oxygen permeation speed is twice or more as high as the nitrogen permeation speed. Oxygen-enriched air can be obtained with a simple configuration.

  The vibration of the pump 10 is stabilized by the vibration isolating effects of the vibration isolating materials 38 and 39 and the legs 42 sandwiching the sheet metal 37, and the cushion 45 can suppress the propagation of the vibration while making the thermal fuse 43 contact the motor 10a.

  On the other hand, the oxygen-enriched air sent out from the unit outlet 6 of the oxygen-enriched membrane unit 2 by the pump 10 is discharged from the outlet 21 of the headset unit 13 through the first and second connecting pipes 23 and 24. However, since the discharge port 12 can be turned up and down, it is possible to prevent the connecting pipe from bending and preventing air from flowing. The water vapor contained in the oxygen-enriched air tends to go from the muffler pipe 11 and the discharge port 12 on the downstream side to the discharge port 21 of the headset unit 13, and furthermore, to the path from the unit discharge port 6 to the headset unit 13. Water droplets that have condensed on the way (for example, the first connection pipe 23) also try to go to the discharge port 21 of the headset unit 13. However, in this embodiment, since the liquid pool 22 is provided in the middle of the path (the first and second connecting pipes 23 and 24) connecting the main body 1 and the headset unit 13, most of the condensed water carried is Then, it collides with the inner wall or the like in the liquid pool 22 and is stopped in the liquid pool 22.

  In addition, the liquid pool 22 is easily opened and closed by a screw or the like within one rotation so that it can be easily attached and detached. Since the pipe section A30 and the pipe section B31 are provided so as to protrude inside, even if dew water accumulates in the liquid pool 22, This condensed water is difficult to flow out of the pool 22 to the second connecting pipe 24 or the like. Further, since the central axis of the pipe section B31 protruding into the liquid pool 22 is provided to be shifted from the central axis of the pipe section A30, the carried steam can also be transferred from the pipe section A30 to the pipe section. It is possible to prevent the air from directly flowing into B31 and also prevent the sound caused by the collision of the air currents between the pipes. For this reason, it is also possible to prevent discomfort caused by water droplets scattered from the outlet 21 of the headset unit 13 together with the oxygen-enriched air at the mouth of the user. Further, since the first and second connecting tubes contain an antibacterial agent and / or an antistatic agent, they can prevent propagation of various bacteria and adhesion of dust and can be used cleanly.

  Further, like the oxygen, the oxygen-enriched membrane 4 also has a higher water vapor permeability than nitrogen, and when operated in a humid atmosphere, a large amount of water vapor is contained in the oxygen-enriched air discharged from the unit outlet 6. Although it is included, the liquid pool 22 makes it possible to prevent damping, and the oxygen enrichment means using a polymer film such as the oxygen enrichment film 4 is particularly effective.

  Further, the oxygen-enriched air discharged from the discharge port 12 provided on the side surface of the main body 1 passes through the first connecting pipe 23, the liquid reservoir 22, and the second connecting pipe 24, and the earpiece left 25. To the bottom surface 28. Then, the user moves the bendable flexible joint 29 that is attached to the bottom surface 28 of the ear pad left 25 and connects the bottom surface 28 and the discharge port 21, and moves the discharge port 21 to the user. By bringing the air closer to the mouth or the nose, the oxygen-enriched air discharged from the discharge port 21 can be sucked from the mouth or the nose.

  Here, the discharge port 21 has, on the upstream side near the surface thereof, a bio-sterilizing filter 34 in which an enzyme is attached to a honeycomb substrate, and on the downstream side near the surface, a HEPA filter 35 of an antibacterial material amenitop, respectively. The bio-sanitizing filter 34 suppresses the activity of the caught bacteria and the like, and further suppresses the activity of the virus. The HEPA filter 35 of the antibacterial material amenitop has a particle size of 99 μm. In addition to removing 7% and controlling the activity of fungi and mold collected by the action of the antibacterial material Amenitop, even if germs etc. are generated in the middle of the route, the germs etc. together with oxygen-enriched air can be removed by the user. Inhalation can be prevented at the final stage before the discharge port 21 to be sucked by the user. Further, since the discharge port 21 includes the discharge port main body 21a and the lid 21b, the filters and the spherical body 46 can be easily replaced. The spherical body 46 is formed by impregnating with a liquid, so that the volatilization amount of the fragrance can be restricted as compared with the liquid, the handling is easy, and the influence on the deterioration of the surrounding resin is small.

  In addition, since the flexible joint 29 is provided on the bottom surface 28 of the left ear part 25, it can be freely bent in any direction without being restricted by the wall surface of the left left ear part 25. That is, when the flexible universal joint 29 is provided on the side wall of the earpiece left 25, the wall becomes an obstacle and can be bent only in one direction, and the user mistakenly attaches the earpiece left 25. When mounted on the right side of the head, there occurs a problem that the flexible universal joint 29 cannot be bent near the mouth and nose of the user, but such a problem is also eliminated.

  Further, the first connecting pipe 23 and the second connecting pipe 24 for connecting the main body 1 and the headset unit 13 are detachably provided, so that the first connecting pipe 23 and the second connecting pipe 23 are respectively provided. When the inside of the tube 24 becomes dirty, it can be removed and washed, and the lengths of the first connecting tube 23 and the second connecting tube 24 can be freely adjusted. It becomes possible to match, and the usability is improved.

  Also, an inner case left 16 and an inner case right 17, which constitute an inner case containing the oxygen-enriched membrane unit 2 and the pump 10, which are main components in the main body 1 of the oxygen enricher, are provided integrally with each other. The rotating shaft 15 of the handle 14 fitted with the bearings 18 and 19 can directly receive the load of the inner case containing the oxygen-enriched membrane unit 2 and the pump 10 via the bearings 18 and 19.

  Therefore, even if other outer parts constituting the main body 1 are damaged, the handle 14 is not directly affected, and the handle 14 is detached from the main body 1 while carrying the main body 1 with the handle 14. The body 1 does not fall on the upper leg of the user's foot, and the safety is improved.

  Further, since the handle 14 is provided with the holding portion 20, when the headset unit 13 is not used, the holding portion 20 is provided with the first connecting pipe 23 made of a tube of vinyl chloride or the like. The connection tube 24 is wound around, or the headband 27 of the headset unit 13 is hooked on the holding portion 20, so that the headset unit 13 is not left unattended, and the handle 14 is turned compactly. It can be stored without obstructing. If the headset unit 13 is put in a bag and hooked on the holding portion 20, dust can be prevented from being adhered even when stored for a long period of time, and a power cord can be hung. When the bag containing the fragrance is lowered, the bag is located in front of the exhaust port 8, so that the scent diffusion effect is enhanced.

  In addition, water droplets (which can be almost eliminated by shortening the connection tube 24) from the second connection tube 24 made of a tube of vinyl chloride or the like to the headset unit 13 or the headset unit 13 Water droplets condensed inside are usually difficult to drain, and cannot be drained inside, accumulate, causing mold and bacteria to be generated, or inhaling into the human body together with oxygen-enriched air. In this embodiment, since the second connecting pipe 24 is detachably connected to the bottom surface 28 of the headset unit 13 in the present embodiment, the second connecting pipe 24 is simply attached to and detached from the bottom surface 28, so that the bottom surface 28 This makes it possible to easily drain the water droplets that have collected and accumulated in the water.

  In addition, this oxygen-enriching machine automatically performs air-blowing operation following normal operation, so that even if high-humidity air accumulates inside the equipment and piping due to use on rainy days, it can be replaced. This creates an environment where it is difficult for germs to propagate during storage. In addition, the display shows the operating state and the stopped state in the series, and in addition to the temporary stop state, the air volume during the blow operation is twice or more the air volume during the normal operation and the ventilation can be performed quickly The user is notified before the difference in the blowing sound at the time of the occurrence occurs, so that the user can remove the headset from being worn. Further, by providing a high-performance filter such as HEPA at a portion where air is taken in during the air blowing operation, it is possible to prevent bacteria from entering the piping.

  In addition, as shown in FIG. 12, a filter 80 having a water-repellent function such as silicon may be provided, for example, at an appropriate position in the supply path of oxygen-enriched air without providing a container-type liquid pool, to form a liquid pool. When water vapor tries to pass through the filter 80, it becomes water droplets due to the water-repellent function and accumulates on the upstream side of the filter 80, so that the passage of water vapor can be prevented, and the same as the liquid pool 22 in the previous embodiment. It is possible to achieve the effect of.

  Further, if a negative ion generator (not shown) is provided, and the negative ions generated by the negative ion generator are mixed with oxygen-enriched air to form a form that can be sucked by the user, the relaxing effect is expanded. You can also get it.

  In the above-described embodiment, a method of generating a high concentration of oxygen-enriched air using a difference in the speed at which molecules pass through a polymer flat membrane (flat membrane method) is used as the oxygen enrichment means. However, the present invention is not limited to this. A system using a hollow fiber membrane (hollow fiber membrane system), a system using adsorption and desorption of gas on a solid surface such as zeolite (PSA system), or an oxygen generator A similar effect can be obtained in a system (chemical system) utilizing a chemical reaction of a chemical substance such as a reaction of water with water.

  Further, in the headset 13 of the above-described embodiment, the earpiece left 25 and the earpiece right 26 are provided so as to be in contact with the ears, respectively. is there. In addition, there is no problem even if only one of the left ear part 25 and the right ear part 26 is provided. In this case, there is no problem even if the headband 27 is not provided.

  Further, in the headset 13 of the above embodiment, the flexible joint 29 having the discharge port 21 at the end thereof is connected to the ear pad left 25, but even if it is connected to the ear pad right 26, there is no problem. Not something.

  Further, in the headset 13 of the above embodiment, the second connection pipe 24 connected to the liquid pool 22 is connected to the ear pad left 25, but there is no problem even if the second connection pipe 24 is connected to the ear pad right 26. Things.

  Further, in the above-described embodiment, the headset unit 13 worn by the user on the head is exemplified as the oxygen-enriched air discharging means. However, the present invention is not limited to this. Also, there is no problem with the type of wrapping around the arm or torso with Velcro (registered trademark), and there is no problem with the type of tie or other clothing that is fixed with pins. A type that covers a part of the face using ears or the like, such as a dust mask, does not cause any problem.

  In the above-described embodiment, the liquid pool 22 is configured to be able to be separated and the water drops accumulated inside can be discharged. However, the present invention is not limited to this. As shown in FIG. The main body portion 22c is integrally formed, and a detachable drain cap 22d is provided on a part of the main body portion 22c by a screw method or a press-fitting method, and the drain cap 22d is removed from the main body portion 22c of the liquid pool 22. The same effect can be obtained even when the internal water is discharged. Of course, a fragrance such as the spherical body 46 may be put in the liquid pool 22.

  The liquid pool may be provided anywhere on the path to the discharge port 21, for example, on the bottom surface 28 of the ear pad left 25 itself or in the middle of the universal joint 29.
