Oxygen generators

Abstract

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.
