Oxygen generator with oxygen-producing column having center bore

An oxygen generator with an oxygen-producing having a center bore, comprising:

• an impact-activated ignition mechanism (100), an end cover (3), a cylinder (8), a bell-shaped hood (5), a thermally insulating inner cylinder (10), an oxygen-producing column (200), a thermally insulating material (9), a support bowl (12), a gas purification material (13), a safety valve (300), an isolation net (14), an oxygen-discharging end cover (15) and an oxygen-discharging joint (17);
• the cylinder (8) is provided with the end cover (3) at one end;
• the impact-activated ignition mechanism (100) is fixed on the end cover (3);
• the oxygen-producing column (200) is coaxially located with the cylinder, one end of the oxygen-producing column is connected to the impact-activated ignition mechanism (100), and the other end of the oxygen-producing column is connected to the support bowl (12);
• the support bowl (12) is connected to the isolation net (14) and configured for preventing generated impurities from passing through the oxygen-discharging end cover (15);
• the thermally insulating inner cylinder (10) is arranged on the outside of the oxygen-producing column (200) and the thermally insulating material (9), and configured for reducing heat generated by the oxygen-producing column (200) from being transferred to an external environment;
• the bell-shaped hood (5) is configured to cover a connection of the oxygen-producing column (200) and the impact-activated ignition mechanism (100);
• the support bowl (12) is arranged at a rear end of the oxygen-producing column (200), and filled therein with the gas purification material (13);
• the oxygen-discharging end cover (15) is arranged at a rear end of the gas purification material (13);
• the oxygen-discharging joint (17) is arranged on the oxygen-discharging end cover (15);
• the safety valve (300) is arranged on the oxygen-discharging end cover (15).
