ABSTRACT:
Disclosed is a rod-shaped gas igniter including an ignition nozzle, a finger-operative piezoelectric generator, a liquefied gas reservoir, means responsive to the operation of the piezoelectric generator for opening valve means associated with the liquefied gas reservoir, thereby permitting gas to flow to the ignition nozzle, an inner protecting hollow cylinder having longitudinal slots circumferentially spaced for ventilation and enclosing the ignition nozzle, and an outer metal hollow cylinder having longitudinal holes circumferentially spaced for ventilation and encircling the protecting hollow cylinder, the longitudinal slots and holes of the inner and outer hollow cylinders being staggered to each other. The staggering arrangement of slots and holes in the inner and outer hollow cylinders is effective to prevent direct invasion by air from the longitudinal holes of the outer hollow cylinder to the ignition nozzle, permitting the air to leave entrained dust and impurities on the slot adjoining portions of the inside hollow cylinder. Thus, dust-free air is supplied to the ignition nozzle.
