Abstract

An oxygen rich air inhaler for use in stress relief and fatigue recovery has a casing, an inlet duct and an exhaust duct. The casing is separated into a compressor chamber and an adsorber chamber by a partition. The inlet duct has an inlet open to an end wall on the side of the adsorber chamber and provided at an upper portion of the adsorber chamber so as to communicate with the compressor chamber. The exhaust duct has an exhaust outlet open to an end wall on the side of the adsorber chamber and provided at a lower portion of the adsorber chamber so as to communicate with the compressor chamber. A suction fan and at least one compressor are disposed in the compressor chamber. At least two adsorbers, which communicate with the compressor via a selector valve, and an oxygen rich air tank, communicating air outlets of the adsorbers, are disposed in the adsorber chamber. An air inlet for the compressor and an exhaust outlet for air desorbed from the adsorbers are disposed downstream of the compressor chamber. An inhalation mask communicates with oxygen rich air tank for inhaling oxygen rich air.
