A chemical core for an oxygen generator. The chemical core is capable on ignition of producing oxygen by chemical reaction. A first end of the chemical core has a smaller cross-sectional area than a second end of the chemical core such that the ratio of the cross-sectional area of the second end to the cross-sectional area of the second end is 0.20:1 or more.

Oxygen generators

An oxygen generator comprising a housing and a chemical core within the housing, the chemical core being capable on ignition of producing oxygen by chemical reaction. An ignition apparatus within the housing is for igniting the chemical core, and a collection apparatus within the housing collects oxygen produced by the chemical core. The ignition apparatus comprises an ignition handle accessible from outside the housing, the ignition handle being arranged to be rotatable by hand, and an ignition block disposed within the housing, the ignition block being arranged, when rotated in contact with the chemical core, to ignite the chemical core. A thermal isolator between the ignition handle and the ignition block is arranged to transmit rotational force from the ignition handle to the ignition block.

An oxygen generator comprising a housing and a chemical core within the housing, the chemical core being capable on ignition of producing oxygen by chemical reaction. An ignition apparatus within the housing is for igniting the chemical core, and a collection apparatus within the housing collects oxygen produced by the chemical core. The collection apparatus comprises a cooling chamber having an inlet through which oxygen produced by the chemical core enters into the cooling chamber, and an outlet through which oxygen in the cooling chamber leaves the cooling chamber. The interior of the cooling chamber has at least one wall arranged in the path of oxygen flowing from the inlet to the outlet.

An oxygen generator comprising an oxygen generating unit including: (a) a chlorate oxygen generating candle for generating oxygen when ignited; and (b) an ignition device for igniting the candle to initiate oxygen generation from the candle. The candle is arranged during operation to sustain propagation of a plurality of burn fronts therethrough, the fronts propagating in different directions.
