SPACE OXYGENATING DEVICE

PURPOSE:To provide a proper supplying of air having high concentration of oxygen which is more clean than that of the surrounding atmosphere into a limited space by a method wherein artificial oxygen is mixed with air under a proper concentration in a single form or together with chemical aromatic gas. CONSTITUTION:Either compressed oxygen bomb or oxygen producing device 2 is arranged outside of or inside of an athletic room 1, for example, a volume of oxygen supplied through a pipe 4 arranged from the room is automatically controlled by an automatic control mechanism 3 for controlling the volume of oxygen in response to various conditions in the athletic room 1, and then the oxygen is mixed with air and supplied from the injection ports 5 into the room 1. The oxygen remained in the room and the stained oxygen are suctioned through the inlet ports 6 made in the floor surface, for example, cleaned through the air cleaner mechanism 7 arranged on the floor surface etc. and again mixed with the new oxygen to follow the circulating cycle.
