Definitions

  • the present invention relates to a portable oxygen generator.
  • Oxygen suppliers have become popular as means for speeding up recovery from fatigue after heavy physical exercise or the like.
  • An oxygen supplier of this type is shown in Japanese Patent Provisional Publication 61-85969, wherein a sealed container contains peroxide and catalyst into which water is put to generate oxygen. The oxygen is aspirated through a hose.
  • this supplier has no cleaning or humidifying channels for the generated oxygen, the oxygen is not suitable for direct human respiration. In particular, if aspirated for about five minutes or longer, the dry oxygen generated is liable to have a negative effect on the human body.
  • An oxygen generator comprises a container and a top lid.
  • the inside of the container is divided into a reaction chamber and a cleaning/humidifying chamber, which has gas outlet means adjacent the top.
  • a gas passage extends within the container, and opens at one end into an upper portion of the reaction chamber and at the other end into a lower portion of the other chamber.
  • the oxygen generator is made of plastic and includes a container 10 having an open top end.
  • the container 10 is formed with a top rim 11 and an outer flange 12 adjacent the top.
  • the inside of container 10 is partitioned into two chambers 13 and 14 by a vertical wall 16, which is formed integrally with a vertical tube 18.
  • the tube 18 has a top inlet which opens into an upper portion of the larger chamber 13 through a check valve 19.
  • This valve 19 is mounted pivotably on a horizontal axis 21, and has a hole 20 which is small enough to resist liquid flow from the first chamber 13.
  • the tube 18 has a bottom outlet port 22 formed with a number of blowout holes 24 with a diameter of 1-1.5 mm, which open into a lower portion of the smaller chamber 14.
  • a lid can fit tightly over the top rim 11 of container 10 and the top end of partition 16.
  • the lid 26 is formed with an outlet hole 28 over the smaller chamber 14.
  • the lid 26 has a pivotable latch 30 supported on a horizontal axis 32 on each side.
  • a decorative case or shell 34 surrounds the container 10 and has a top end engaging the flange 12. As shown in Fig. 3, the top end of case 34 is formed with a hook 36 extending outwardly adjacent and for engagement with each latch 30. The hook 36 is formed with a horizontally elongated groove 38 in its upper surface.
  • the container flange 12 further extends outwardly adjacent and along each case hook 36, and is formed with a horizontally elongates nail 40 in its lower surface for engagemwnt with the groove 38. This engagement reinforces the hook 36 and secures its engagement with the latch 30.
  • a cup-shaped plastic mask 42 has an open end 44 fitting over one's nose and mouth, and a pair of brackets or ears 46 for connection with a band (not shown).
  • the mask 42 has an oxygen inlet nozzle 48 formed therethrough at a lower position adjacent the other end and connected through a hose 50 to the lid hole 28.
  • the mask 42 has air inlet holes 52 formed therethrough near the nozzle 48.
  • the mask 42 also has exhaust slits 54 formed therethrough above the nozzle 48 and holes 52.
  • the total area of air holes 52 is such that the amount per unit time of air flowing therethrough from outside is 3 to 6 times that of oxygen supplied through the nozzle 48.
  • the oxygen concentration in the total volume of air is 40-60%. Therefore, when the amount of oxygen supplied through the nozzle 48 is 1.2-3 liters per minute, the amount of air taken in is in the range of 3.5-5.5 liters per minute, with a maximum of 9.5-11.3 liters per minute.
  • Reaction takes place in the first chamber 13 to generate oxygen. Because the reaction occurs in a large amount of water having a high thermal capacity, reaction heat is absorbed by the water so that the container 10 is not exposed directly to high heat.
  • the gas flows into the tube 18, expells the water from it into the second chamber 14, and is ejected as fine bubbles B through the small holes 24 into this chamber 14. While rising through the water in the second chamber 14, the oxygen is efficiently cleaned and humidified before filling the upper space of this chamber. The gas then flows through the hose 50 into the mask 42.
