摘要： PURPOSE: To provide an oxygen generator capable of surely performing the thermal decomposition of a whole candle and also lowering the temperature of a housing by supplying oxygen generated by the thermal decomposition of an oxygen generating material induced by an ignition to the outside through a gap between a cylindrical body and a heat insulating material, and through the heat insulating material. CONSTITUTION: Since a ring-shaped airtight space 39 is formed between a cylindrical body 37 and a housing 40 in this oxygen generator, and a candle 32 is covered by a copper cylindrical body 37 which functions also as a heat insulating material, the quantity of heat conveyed to the housing 40 is extremely small. Therefore, the whole candle is heated uniformly by widely lowering the temperature of the housing 40, reducing the heat transmitted from the candle 32 to the space 39 as small as possible by means of the cylindrical body 37, and further effectively supplying the heat to the whole part of the candle 32 inside. Thus, from right hand side, the candle 32 generates oxygen by performing the thermal decomposition successively without an interruption in its halfway and the whole candle 32 is thermally decomposed to convert NaClO3 into NaCl. In this way, the prescribed amount of oxygen flow can be supplied to the outside following a prescribed pattern.

摘要： PROBLEM TO BE SOLVED: To provide an oxygen generator which is capable of generating a desired flow rate of oxygen by preventing the dislodgment and chipping of an oxygen generating agent without increasing the weight over the entire part too much and has excellent vibration resistance. SOLUTION: This oxygen generator is provided with a planar vibration resistant member 34 between a candle holder 68 for supporting one end of a candle 32 and a cap member 42 inserted with an ignition device part F' engaged with the center of this candle holder 68 so as to cover the one opening of a housing 40 in such a manner that this member engages with the central part of the ignition device part F'. The outer end 34a of this vibration resistant member 34 and the inside end 42b of the cap member 42 are engaged with the housing 40. In addition, the outside end 34a of the vibration resistant member 34 and the inside end 42b of the cap member 42 are coupled to each other.

摘要： PROBLEM TO BE SOLVED: To prevent the interruption of thermal cracking during its course by covering the outer periphery of a cylindrical heat insulating material packed with an oxygen generating agent with a cylindrical body made of a material having oxygen generating agent resistance and forming a space between the cylindrical body and a housing. SOLUTION: A hammer piston 48 is moved leftward of Fig. by a spring 47 and is brought into collision against a detonator 43 to generate sparks when a label 49 and a pin P are removed. A gunpowder section 33 and an initiator section 34 are then fired and oxygen is kept generated by thermal decomposition. The oxygen of high temp. flows in the outward direction of the diameter along the base of a candle holder 38 and flows leftward of Fig. by passing between the cylindrical body 37 made of the material having corrosion resistance, reaction inactiveness and heat resistance to the oxygen generating agent 32 and the cylindrical heat insulating material 36 and along the heat insulating material 36, thereby heating the candle 32 as the oxygen generating agent. The candle is thermally decomposed from rightward of Fig. and the heat is transferred leftward. The oxygen is thus successively generated and is cooled during the passage through a cylindrical opening 52a and a filter 53. The oxygen is then supplied from cooling and leading-out pipes 57a, 57b. A housing 40 is held at a lower temp. by the air heat insulating part of the space 39.
