Definitions

  • the invention relates to a device for generating oxygen according to the preamble of claim 1.
  • the division of the device into reaction containers and transparent Bubble detection chamber reduces the usable area of the reaction container. This will result in the reaction vessel the dumping height, for example in the case of powder Oxygen generating agent, increased. In addition, the generated Oxygen the full water level in the vertical Flow through the bubble detection chamber, reducing the water pressure in the reaction vessel in which the oxygen generation process expires, is increased. Both the dumping height of the Oxygen generating agent as well as the pressure inside of the reaction container have a negative impact the oxygen production process.
  • the bubble detection chamber is according to the invention in the device arranged parallel to the lid immediately below it and therefore clearly visible from the top of the device.
  • oxygen bubbles present in the water are due to the transparent cover easily recognizable.
  • the water filling of the shell is separated from the inside of the reaction vessel in such a way that from there Oxygen can get into the bubble detection chamber one takes claim 8.
  • the special filter used according to the invention is said to Claim 9 preferably arranged centrally on the bottom of the shell be so that the oxygen at the lowest point of the Shell enters the water filling and then in the form of Bubbles get to the oxygen extraction opening.
  • the embodiment according to claim 10 ensures that the Oxygen bubbles relatively slow and over a relative great path along the transparent top wall of the bowl run.
  • the oxygen generating agent preferably consists of two separated chemical substances, especially in the form of Tablets and / or powder, according to P 196 02 149.9.
  • the device for generating oxygen an essentially cylindrical reaction vessel 2 with a gasket 6 interposed and detachably connectable, at least partially transparent Cover 3, the central and radially outside opposite an annular, slightly rising radially outward Area 9 has elevations 8 and 11 respectively. It is sufficient, if the cover 3 is transparent only in the annular region 9 is.
  • a ring segment 11 'in front on the top of which there is an oxygen removal opening 12 is arranged, for example a breathing mask for medical ventilation purposes a user can be connected.
  • the sieve 17 is weakly conical, the cone angle being at least 5 ° from the horizontal should be.
  • the cone shape can be radial from increasing or decreasing or alternating from the inside to the outside be rising and falling.
  • the screen 17 consists of a lattice-shaped Support structure 38 and one attached to its underside Plastic mesh with a mesh size of 200 ⁇ m to 400 ⁇ m.
  • spiral guide devices 32 are arranged, which is a radial flow from the inside out give an additional peripheral component.
  • the oxygen now formed rises in the water 13 in Form of bubbles 33 on that in the room above the height 15 enter so that there is an oxygen cushion forms. Due to the pressure generated in this way, the oxygen arrives along the arrows in the pipe section 23, then on the upper edge down into the annular gap 24 between the walls of the pipe section 23 and the elevation 8 of the cover 3, where it is in the form of bubbles in the ring shell 21 Immersed water and at the lower edge 34 of the Annular gap 24 along in the widening in the radial direction Space 16 between the annular area 9 and reaches the bottom 26. There the bubbles follow due to the Guide device 32 in approximately a spiral path, wherein by the user through the transparent area 9 can be observed well.
  • the Reaction container 2 in the lower area an inward Ring projection 10, which is about halfway up the bearing surface 5 for the ring sieve 17 is formed the one provided below with a plastic fabric 39 Support structure 38 rests, the tube 18 in the middle wearing.
  • the shell 21 ' is not a ring shell, rather than a circular horizontal cross section having continuous container formed in the Bottom in the middle a filter 35 is arranged, which the oxygen from the reaction vessel into the bubble detection chamber 16 or the water filling therein lets rise, but prevents the water from the shell 21 'flows into the reaction container 2.
  • an opening 40 is provided in which by means of a bayonet lock connection and a seal 36 a connector 37 is inserted, which is on the side of the oxygen removal opening 12 has.
  • the oxygen increases in shape of bubbles 33 along the path 41 indicated by dashed lines up to level 14, where it emerges from the water filling and through opening 40 and the interior of the hollow fitting 37 reaches the oxygen removal opening 12, where the Oxygen in a suitable form, for example by means of a Hose that can be discharged to the user.
  • the locking ring 43 can also be seen in FIGS. 3 and 4, which on the inside has a bayonet-type construction owns and in the closed state the lid 3 am Specifies reaction vessel 2.
  • the oxygen generated in the reaction container 2 must be at his Way to the removal opening 12 only the low water pressure of the water in the annular shell 21 overcome so that to produce highly visible oxygen bubbles no significant pressure losses accepted Need to become.
