ABSTRACT:
A lighter device is described featuring a new burning system which is of a rugged structure and comprises relatively few parts which are easy to manufacture and to assemble. The novel burning system provides for reliable operation of the device over an extended period of operable life. The novel burning system comprises combined vaporizer-and-burner unit in the form of a short metal tube arrangement comprising two sections of metal tube axially aligned with one another. The upper section may have a larger diameter than the lower section. The combined vaporizer-and-burner unit is arranged as a separate member separately from and above the nozzle in a predetermined vertical distance therefrom. A perforated metal sheet partitions the two tube sections of the vaporizer-and-burner unit thus providing for additional intensive mixing and vaporizing the gas stream entering at the lower end of the unit and ambient air drawn into the unit by the gas jet. In the upper section of the vaporizer-and-burner unit there is a catalyzer wire which will provide for re-ignition of the gas/air mixture in case the lighter flame would become extinguished by ambient wind flow.
