A cigarrette gas lighter is disclosed which enables a selection between a substantially clear flame (burning gas) which is windshielded or presents an increased resistance to the wind effect and a red natural flame which can be visually easily recognized, wherein the selection is facilitated. A cylinder member (3, 30) has an air inlet port (30a) at its lower end while a mixing tube (8) is formed with an air suction port (8b) in its lateral surface. A flame switching tube (7) surrounds the outer periphery of the mixing tube (8), and when it is located at its first position, the flame switching tube (7) closes the air suction port (8b) while an open/close member (7g) leaves the air inlet opening (30a) open. When the flame switching tube (7) is driven to its second position, the flame switching tube (7) opens the air suction port (8b) while the open/close member (7g) closes the air inlet opening (30a).
A lighter including a fuel tank (FT) including a gas discharge valve, a cylinder member (3), a nozzle member (7d) which projects into an internal space of the cylinder member from below, a gas guide sleeve (8) for guiding a fuel gas which finds its way out of the fuel tank (FT) through the gas discharge valve thereof to the nozzle member (7d), an air suction port (8b) formed in the lateral surface of the gas guide sleeve (8), and ignition means for igniting a fuel gas which is led through the nozzle member (7d) into the cylinder member (3);
A lighter according to claim I in which the ignition means comprises a piezoelectric high tension generator including an electrode mounted on the cylinder member (3) in opposing relationship with the nozzle member (7d), the second shutter member (7g) being mounted on the lateral surface of the first shutter member (7h), the first shutter member (7h) comprising a lower opening through which the gas guide sleeve (8) is inserted, a top opening (7a) in which the nozzle member (7d) is a press fit, and a lateral opening (7b) formed in the lateral surface at a location between the top opening (7a) and the second shutter member (7g), the lateral opening (7b) being closed by the gas guide sleeve (8) when the first shutter member (7h) is located at its first position and being located above the top end of the gas guide sleeve (8) to provide a communication between the gas guide sleeve (8) and the internal space within the cylinder member (3) when the first shutter member (7h) is located at its second position.
