Abstract
A handy oxygen generator including a casing defining a reaction chamber, an air accumulator and an air passage between the reaction chamber and the air accumulator, a hand pump for pumping air into the reaction chamber to increase its inside pressure, a chemical module mounted in the reaction chamber and containing two separated chemicals, a plunger mounted on the reaction chamber for operation by hand to break the chemical module, enabling the two chemicals to induce a chemical reaction and to release oxygen into the air accumulator during the chemical reaction, an air outlet pipe with an air filter suspending in the air accumulator, and a mouthpiece connected to the air outlet pipe for the user to breathes in oxygen from the air accumulator.
Claims6
A handy oxygen generator comprising:
- a casing defining a reaction chamber, an air accumulator, and an air passage between said reaction chamber and said air accumulator, said reaction chamber having a top-open mouth covered with a screw cap;
- an air intake pipe mounted in said reaction chamber, said air intake pipe having a bottom end coupled with an air filter element suspending inside said reaction chamber, and a top end coupled with a connector disposed outside said reaction chamber;
- an air pump connected to the connector of said air intake pipe and operated to pump air into said reaction chamber through said air intake pipe;
- a chemical module mounted in said reaction chamber and retained in place by said screw cap, said chemical module comprising a first chemical, a second chemical, and partition means adapted to separate said first chemical from said second chemical;
- plunger means mounted in a hole in said screw cap and having a handle disposed outside said screw cap for operation by hand;
- an air outlet pipe mounted in said air accumulator, said air outlet pipe having a bottom end coupled with air filter means suspending in said air accumulator, and a top end coupled with a connector disposed outside said air accumulator;
- and
- a mouthpiece connected to the connector of said air outlet pipe for breathing in air from said air outlet pipe;
- wherein when said plunger means is pressed down, said partition means of said chemical module is broken, causing said first chemical to mix with said second chemical and to induce a chemical reaction and to release oxygen during the chemical reaction, permitting released oxygen to pass from said reaction chamber into said air accumulator through said air passage and then to be breathed in by the user through said mouthpiece via said air outlet pipe.
