Abstract
The present invention is a oxygen generating device which comprises: a container having a mouth and a neck surrounding the mouth; a tank which has an annual flange for establishing a gas tight seal between the tank and the neck; a dome assembly which is engageable with the neck and extends upwardly to define a dome chamber above the neck; and means for permitting oxygen generated in the tank to flow into the dome chamber by bubbling through a liquid contained in the dome base; the dome base having an outlet connection through which oxygen can leave the chamber and where at least part of the dome is transparent so as to render the inside thereof visible from the outside of the dome.
Claims8
An oxygen generating device comprising:
- a dome;
- a base attachable to the dome forming a dome assembly, having a volume for containing the reaction of an oxygen gas producing source and which partitions the oxygen gas producing source from the inside of the dome assembly;
- a tank assembly attachable to the dome assembly for containing the oxygen gas producing source;
- an inlet between said base and said dome whereby oxygen formed by the oxygen gas producing source in the tank assembly passes from said base into said dome;
- humidifying means for delivering oxygen from said inlet into water to humidify the oxygen within the dome, wherein said humidifying means is a tube formed in a U-shape connecting the inlet to a bubble fitting submerged in water in the dome;
- said bubble fitting comprising an outlet for the oxygen gas delivered from the inlet to bubble through the water into the dome;
- and,
- an outlet in said dome for delivering oxygen out of the dome.
An oxygen generating device comprising:
- a cylindrical tank assembly, said assembly having a mouth, a threaded neck surrounding the mouth, and a tank attachable thereto having an annular flange for establishing a gas tight seal between the tank and neck;
- said tank having sufficient volume to contain a chemical reaction therein which produces oxygen gas;
- a cylindrical tank sleeve into which the cylindrical tank fits so as to be surrounded by said sleeve;
- attachment means at the base of the sleeve for connecting the sleeve to the cylindrical tank;
- a dome;
- a base partitioning the cylindrical tank from the inside of the dome, said base having a threaded wall that screws into the dome, and said base attachable to the threaded neck of the cylindrical tank;
- a gasket between the dome and base;
- a gasket between the base and the cylindrical tank;
- an inlet in said base whereby oxygen gas from the tank passes through said base into said dome;
- a bubble fitting outlet for bubbling oxygen from the inlet through water in the humidifier dome;
- a tube formed in a U-shape connecting the inlet to the bubble fitting outlet;
- and
- a recessed nipple outlet in the top of the dome for delivering oxygen out of the dome.
A portable oxygen generator having an open top tank and a dome detachably mounted atop said open top tanks said dome having a bottom formed with an inlet, a tube mounted within said dome that extends upwardly from said inlet to a selected height above said bottom and then downwardly to a bubble fitting tube opening located adjacent said dome bottom, and wherein said dome has an outlet located above said selected height, whereby oxygen generated in the tank may be passed through a body of water with a surface level below the selected height in the dome to become humidified and out of the dome as a humidified stream of oxygen without water entering the tank.
