HIGH EFFICIENCY OXYGEN GENERATOR OF TWIN TOWER TYPE

摘要

The purpose of the present invention is to provide an oxygen generator in which a configuration is simplified by changing the structure of the inner space of a cover body at one side of an absorption bed for discharging oxygen. The oxygen generator for storing concentrated oxygen gas by separating nitrogen and oxygen from compressed air comprises: a first cover body and a second cover body which are adherently installed at both sides of the adsorption bed in a longitudinal direction; a flexible space part which is installed in the inner space of the first cover body in order to be sealed from the outside, is connected to a first adsorption part and a second adsorption part by an adsorption part connection hole penetrated through the first cover body and is connected to an oxygen storage part through an oxygen supply hole penetrated through the first cover body; a first check valve safe receipt part and a second check valve safe receipt part which are installed to be in contact with the adsorption part connection hole in flexible space part; and a first check valve and a second check valve which are safely arrived in the first check valve safe receipt part and second check valve safe receipt part and blocks and opens the adsorption part connection hole by movement which closely attaches to and separates from the bottom of the first check valve safe receipt part and second check valve safe receipt part. The first check valve and second check valve include: a block plate which blocks the adsorption part connection hole by being closely attached to the adsorption part connection hole; a main body in which one end is blocked by the block plate and the other end is opened; an elastic body which elastically supports the block plate in order to be closely attached to the adsorption part connection hole; and an orifice hole which is formed to be penetrated in the block plate and connects the adsorption part connection hole and the flexible space part at all times.
