OXYGEN CONDENSING APPARATUS

摘要

Disclosed is an oxygen condensing apparatus comprising a pair of adsorbing cylinders for causing compressed air to pass through an adsorbent of zeolite contained in a cylinder, to adsorb nitrogen selectively into the adsorbent thereby to produce oxygen, filter means for filtering the raw air for the compressed air, compressor means driven by a motor for acquiring the compressed air from the air filtered by the filter means, a rechargeable battery for an electric power supply to drive the motor drive and so on, a change valve changed to feed the compressed air alternately to the pair of adsorbing cylinders, and a container for reserving the oxygen produced. The compressor means includes a cylinder chamber, in which a piston driven reciprocally in the crank motions by the electric motor is guided in a sealed state, and a main housing having an air suction port formed therein, and is constituted such that the filter means and the compressor means are integrated through the air suction port.
