The pump 10, the oxygen enrichment membrane unit 2, and the fan 9 are arranged in this order from the front in the main body 1. It is installed. With the above arrangement, the flow of air from the intake port 7 to the exhaust port 8 in the main body 1 can be made smooth to improve the performance of concentrating oxygen in the air, and the air warmed by the heat of the pump 10 can be converted into oxygen. It can be sent to the enriched membrane unit 2 parts and concentrated.

  FIG. 16 is a schematic configuration diagram of a main part showing still another example of the arrangement of components in the in-vehicle oxygen enricher. The pump 10, the fan 9, and the oxygen enrichment membrane unit 2 are sequentially arranged from the front in the main body 1. In this arrangement, the pump 10 and the oxygen-enriched membrane unit 2 that provide resistance to air flow are distributed before and after the fan 9, and the fan 9 is arranged in the center, so that the air can smoothly flow from the air inlet 7 to the air outlet 8. The performance of flowing air and concentrating oxygen in the air can be improved.

  Next, the operation of the on-vehicle oxygen enricher based on the above configuration will be described.

  When the operation switch 32 of the operation control unit 51 is turned ON, the control means (operation control unit 51) for supplying the operation power to the pump 10 operates, the lamp 33 indicating the energized state is turned on, and the time set by the timer Accordingly, the pump 10 is operated and the fan 9 is operated. When the fan 9 is operated, 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 out of the main body 1 from the exhaust port 8. On the other hand, when the outside air passing through the oxygen-enriched membrane unit 2 passes through it, air is sucked into the frame 3 of the oxygen-enriched membrane unit 2 by the operation of the pump 10, and oxygen is easily passed from the place where oxygen easily passes. It becomes enriched air. The oxygen-enriched air is sent to the discharge port portion 12 and discharged from the discharge port portion 12.

  The oxygen-enriched air discharged from the discharge port portion 12 is discharged from the discharge portion 21 of the headset unit 13 through the first and second connecting pipes 23 and 24. Therefore, the user sets the headset unit 13 on the head, moves the flexible universal joint portion 29 and brings the discharge portion 21 close to the user's mouth and nose, thereby enriching the oxygen rich discharged from the discharge portion 21. It becomes possible to suck in the air from the mouth and nose.

  Further, as shown in FIG. 11, the discharge portion 21 of the blow grill unit 52, which is a blowout port of the oxygen-enriched air discharge means, is disposed in the vicinity of the blowout port 53 of the air conditioner mounted on the vehicle 55. In addition, an air flow of high-concentration oxygen that is blown out from the discharge unit 21 on the air flow blown out from the air conditioner can be supplied to the user's mouth. Further, as shown in FIG. 12, by disposing the discharge portion 21 of the blow grill unit 52 on the ceiling of the vehicle, the user can effectively be blown out by blowing an air flow of high-concentration oxygen from the ceiling toward the user. Can be supplied to the mouth.

  Furthermore, as shown in FIG. 13, the discharge part 21 of the ventilation grill unit 52 arrange | positioned in the vicinity of the blower outlet 53 of the air conditioning apparatus mounted in the vehicle 55, and the ventilation grill unit 52 arrange | positioned in the ceiling of the vehicle 55. As shown in FIG. By providing the switching valve 56 which is a switching means for selecting the switching of the high-concentration oxygen air from the discharge portion 21 of the blow grill unit 52 among the multiple blow grill units 52 disposed in the vehicle 55. The user can freely select whether to blow the flow, and by switching the switching valve 56, the blow grill unit 52, which is a blowout port for supplying an air flow of high-concentration oxygen, can be selected.

  Further, since the air inlet 7 is provided on two different surfaces on the front surface and the upper surface of the main body 1, even if one of the air inlets 7 is blocked by being placed on the seat 55a or the floor in the vehicle 55, the other side It is possible to prevent outside air from being completely blocked by sucking outside air from the air inlet 7 provided on the surface.

  In addition, since the air inlet 7 is provided on the upper surface of the main body 1, it is possible to prevent the air inlet 7 from being blocked by the seat 55 aa or the floor surface of the vehicle 55.

  Further, the operation control unit 51 is provided with a lamp 33 for displaying the operation state of the main body 1, and the operation state of the main body 1 can be confirmed by checking the operation control unit 51 part.

  In addition, when the filter 15 at the intake port 7 is clogged with a clogged state and the air flow rate in that portion is reduced, the flow rate sensor detects that the filter 15 is clogged. The lamp 50 is lit red to notify. When the notification lamp 50 is lit in red, it is possible to easily know the clogged state of the filter 15 and to prevent the intake port 7 from being used while being covered with dust.

  In the above embodiment, as the oxygen-enriched air discharge means, the headset unit 13 and the blow grill unit 52 that the user wears on the head are exemplified, but the present invention is not limited to this, and the neck or shoulder There is no hindrance even with the type that hangs on the part, and there is no hindrance even with the type that wraps around part of the arm or part of the body with Velcro (registered trademark) etc., and the type that is fastened to a part of clothing such as a tie with a pin etc. However, there is no problem. Of course, there is no problem even if it is a type that covers a part of the face using ears or the like like a dust mask.

  In the above embodiment, the LED is used as the display means, but it may be a lamp or the like, or may be changed in brightness or blinking instead of being lit, as long as it achieves the intended purpose. It may be configured in any way.

  Further, as shown in FIG. 14, when the main body 1 is installed under the seat 55a of the vehicle 55, the oxygen enricher that prevents the intake port 7 and the exhaust port 8 from being blocked by the vehicle seat and the floor surface. Can provide.

  Further, as shown in the schematic configuration diagram of the main part in FIG. 15, the pump 10, the oxygen-enriched membrane unit 2, and the fan 9 are arranged in this order from the front in the main body 1, thereby exhausting from the intake port 7 in the main body 1. The air flow to the mouth 8 can be made smooth to improve the performance of concentrating oxygen in the air, and the air warmed by the heat of the pump 10 can be sent to the oxygen-enriched membrane unit 2 and concentrated.

  In addition, as shown in FIG. 16, by arranging the pump 10, the fan 9, and the oxygen-enriched membrane unit 2 in this order from the front in the main body 1, Dispersing the oxygen-enriched membrane unit 2 and disposing the fan 9 in the center can improve the performance of smoothly flowing air from the intake port 7 to the exhaust port 8 and concentrating oxygen in the air.

  As described above, the in-vehicle oxygen enricher according to the present invention can be used comfortably without being blocked by the intake and exhaust ports even when used in a vehicle, such as automobiles, trains and airplanes. Applicable to oxygen enrichers used in various vehicles.
