<p>The present invention relates to an oxygen supply elevator (100) which supplies oxygen to the internal space of the elevator or to a separate oxygen mask arranged in the elevator to enable people in the elevator to easily breath and remove smog or the like. The oxygen supply elevator (100) comprises an oxygen containing unit (10) arranged in a facility mounting space (S2) formed in an upper portion of the elevator and containing oxygen having a pressure higher than the atmospheric pressure; an oxygen supply unit (20) connected to the oxygen containing unit (10) through at least one communication channel (30) so as to supply oxygen to an oxygen supply space (S1) formed in the elevator; a valve unit (40) arranged on the communication channel (30) so as to adjust the flow rate of the oxygen discharged from the oxygen containing unit (10); and a control unit (50) connected to the valve unit (40) so as to determine whether to open/close the valve unit (40) or adjust the degree of opening/closure of the valve unit (40).</p> |
