Abstract:
A safety electronic lighter comprising:a housing having a first opening formed in an upper side thereof and a second opening formed in a lower side of said housing, each of said first and second opening having a groove formed in a perimeter edge thereof, each said groove having a pair of bilaterally disposed notches formed therein; a gas tank mounted in said housing in fluid communication with a flame tube for emitting a flame from said housing; electrical power supply means for generating electrical sparks at one end of said flame tube, said electrical power supply means including a battery, a high voltage coil and a battery power supply circuit coupled to said battery; an ignition control switch mounted in said housing and displaceable for electrical contact to said power supply means, said ignition control switch including (a) a first control knob disposed in said first opening of said housing and having a pair of bilaterally disposed projecting rods extending therefrom, said first control knob having a bottom chamber with bevel steps formed therein, (b) a first driving element disposed in said bottom chamber of said first control knob and having a plurality of bevel steps formed on top and bottom sides thereof, said bevel steps on said top side being engaged with said bevel steps within said bottom chamber of said first control knob, (c) a control bar having opposing top and bottom pins extending therefrom and a plurality of bevel steps surrounding said top pin, said first driving element being rotatably disposed on said top pin and said plurality of bevel steps on said bottom side of said first driving element being engaged with said plurality of bevel steps of said control bar, and (d) a spring disposed on said bottom pin for upwardly biasing said control bar, said first control knob being rotatable to displace said projecting rods within said groove to and from said notches; said first control knob being downwardly displaceable when said projecting rods are respectively disposed in said notches and blocked from downward displacement when said projecting rods are respectively disposed external to said notches; and a power control switch mounted in said housing at a location remote from said ignition control switch and electrically coupled to said electrical power supply means, said power control switch including (a) a second control knob disposed in said second opening of said housing and having a pair of bilaterally disposed projecting rods extending therefrom, said second control knob having a bottom chamber with bevel steps formed therein, (b) a second driving element disposed in said bottom chamber of said second control knob and having a plurality of bevel steps formed on top and bottom sides thereof, said bevel steps on said bottom side being engaged with said bevel steps within said bottom chamber of said second control knob, (c) a follower block having opposing top and bottom sides with a pin extending from said bottom side of said follower block and a plurality of bevel steps surrounding said pin, said second driving element being rotatably disposed on said pin and said plurality of bevel steps on said top side of said second driving element being engaged with said plurality of bevel steps of said follower block, (d) a push-button switch having an operating button coupled to said follower block, and (e) a spring disposed between said push-button switch and said follower block for downwardly biasing said follower block and said second control knob therewith, said second control knob being rotatable to displace said projecting rods thereof within said groove of said second opening to and from said notches respectively formed therein, said second control knob being upwardly displaceable when said projecting rods thereof are correspondingly disposed in said respective notches and blocked from upward displacement when said projecting rods are disposed external to said respective notches, whereby simultaneous actuation of said ignition control switch and said first power control switch discharges said electrical sparks.
