  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment)
Hereinafter, an oxygen enricher according to an embodiment of the present invention will be described with reference to the drawings.

  In FIG. 1, the oxygen enricher main body 1 is equipped with oxygen enrichment means for generating oxygen enriched air therein, and includes an intake section 2 for taking in ambient air, and an oxygen enricher. A discharge section 3 is provided through which oxygen-enriched air with an increased oxygen concentration is discharged inside the main body 1. A tube 5 that guides oxygen-enriched air to the vicinity of a user who is a driving operator is connected to the discharge unit 3. The other end of the tube 5 is connected to a headset 6 that is attached to the vicinity of the head when the operator sucks oxygen-enriched air, and a part of the headset 6 is supplied with oxygen-enriched air. A discharge port 7 is provided to discharge the liquid.

  In FIG. 2, the oxygen enricher main body 1 is configured in advance so that the operation switch 8 (which can also be used as a vehicle operation switch), the control means 9, and the environment or state in which the vehicle operator is sleepy. A drowsiness prediction unit 10 for predicting, a power supply unit 11, and an air conveyance unit 12 are provided. Based on the information of the drowsiness prediction unit 10, the control unit 9 sends the power of the power supply unit 11 to the air conveyance unit 12, In this configuration, the main body 1 is operated.

  And although not shown in figure, the oxygen enricher main body 1 is installed by the side of the seat seat in a vehicle, for example, and is connected with the DC voltage jack of a cigarette lighter as the power supply part 11, for example. Further, the oxygen enricher main body 1 contains an air pump as the air transfer means 12 and an oxygen enrichment film for separating oxygen and nitrogen as the oxygen enrichment means, so that the air transfer means 12 is operated. For example, air with an increased oxygen concentration (oxygen-enriched air) is discharged from the discharge unit 3 and is discharged from the discharge port 7 to the vicinity of the driver's mouth through the tube 5.

  Here, the vehicle may be any of cars, trains, airplanes, ships, and the like, and based on the information of the drowsiness prediction means 10, the user who is the driving operator is given oxygen-enriched air. Is intended to supply.

  Next, the principle of obtaining oxygen-enriched air will be described.

  An oxygen-enriched film as an oxygen-enriching means is composed of a flat film of an organic polymer and uses the difference in the speed of molecules passing through the film. It passes oxygen better than nitrogen in the air. Oxygen-enriched air with a high oxygen concentration is obtained. In normal air, the oxygen concentration is about 21% (about 79% nitrogen). The oxygen concentration and air volume of the oxygen-enriched air produced vary depending on the form and size of the oxygen-enriched film, but in this embodiment, the oxygen concentration of the oxygen-enriched air after passing through the oxygen-enriched film is It is about 30% (nitrogen is about 70%).

  The operation of the oxygen enricher configured as described above will be described.

  The information of the sleepiness prediction means 10 in the present embodiment is obtained here based on the brightness information outside the vehicle. As an example, in the case of an automobile, a light sensor is installed on a dashboard to detect the brightness of the traveling environment.

  When the driving operator gets into the vehicle, first, the headset 6 is attached to the head and the driving switch 8 is pressed. Then, the control unit 9 starts to monitor the information of the drowsiness prediction means 10, that is, the brightness information outside the vehicle. Time passes between the driving operations of the driving operator and it becomes evening, the outside of the vehicle becomes dark, the information from the optical sensor which is the drowsiness prediction means 10 becomes below a predetermined value, and the state is predetermined. If it continues for more than time, the control part 9 will drive the air conveyance means 12 before a driving operator feels sleepiness.

  When the air pump that is the air conveying means 12 starts operation, oxygen-enriched air begins to be discharged from the discharge port 7 at the mouth of the driver, and the driver can breathe high-concentration oxygen. Even though the body's body metabolism increases, the head begins to grow up and the surroundings become darker, preventing drowsiness and driving the vehicle more safely.

  At this time, if there is a change such as further darkening, if the controller 9 irregularly varies the discharge of the oxygen-enriched air from the air conveying means 12, in addition to the supply of the oxygen-enriched air, It is effective in preventing drowsiness. This is because if the amount of wind that hits the driver's mouth becomes irregular, a light stimulus is given to the driver's consciousness, so that the driver is less likely to feel sleepy. In addition, as a method of irregularly changing the discharge of oxygen-enriched air, various methods such as changing the discharge amount, the discharge speed, the discharge direction, or a combination thereof can be considered, and the method is not particularly limited. .

  Here, some other examples of the sleepiness prediction means 10 will be described.

  The information of the drowsiness prediction means 10 may be obtained based on the altitude information of the place where the vehicle travels. In other words, by using a pressure sensor that detects altitude and atmospheric pressure and installing it on the dashboard in the same way as an optical sensor, it becomes easier for the driver to feel drowsy due to environmental changes such as the oxygen concentration in the outside air decreasing. Since the oxygen-enriched air can be given according to the altitude and atmospheric pressure information, the driving operator can breathe air having a high oxygen concentration, and drowsiness can be prevented and driving can be performed more safely.

  The information of the drowsiness prediction means 10 may be obtained based on the sound information in the vehicle. In other words, by using a microphone that detects the voice of a person in the vehicle and a frequency sensor, drowsiness is induced from an unstimulated state for the driver that the voice in the vehicle is interrupted for a certain period of time or longer. Since the oxygen-enriched air can be supplied before, the driver can breathe air having a high oxygen concentration, can prevent drowsiness, and can drive more safely.

  The information of the drowsiness detection means 10 may be obtained based on the operation information of the wiper that removes raindrops on the windshield of the vehicle. In other words, by detecting the operation information of the wiper, it is possible to give oxygen-enriched air before the driver easily feels drowsy by seeing a regular constant rhythm of the wiper movement, so the driver can It is possible to breathe air with high oxygen concentration, prevent drowsiness, and drive more safely.

  As described above, in the present embodiment, it is possible to predict in advance that the driving operator of the vehicle is in an environment or a state in which drowsiness occurs, and to obtain optimal oxygen-enriched air. Can be prevented, and a highly usable oxygen enrichment machine that can operate the vehicle more safely can be provided.

  A plurality of examples of information of the drowsiness detection means 10 are shown, and some of them are touched, but the oxygen enricher main body 1 may be operated by appropriate combination information of these information. Further, the change in the generation state of oxygen-enriched air may be on / off of oxygen-enriched air, increase / decrease in oxygen-enriched air, change in supply interval, or the like.

  As described above, the oxygen enricher according to the present invention can obtain oxygen-enriched air before the driver feels drowsy, prevents drowsiness, and can operate the vehicle more safely. Since an oxygen enricher with high performance can be provided, it can be applied not only to automobiles but also to any use such as trains, airplanes, and ships.
