Abstract:
A cigarette lighter, comprising:a. a case having a bottom end and a top end;b. a lighter seat mounted on said top end of said case and having a protruding lock tongue integrally formed at one side of the lighter seat;c. a press-down button mounted on said top end of said case and located adjacent to said lighter seat, the press-down button having a pair of opposite sidewalls and a distal end wall forming a recess with a proximal end opening,d. a latch having a pair of opposite sidewalls, a proximal end wall and a top plate, the latch slidably mounted on top of said press-down button, where the pair of opposite sidewalls slidably engage with said pair of sidewalls of said press-down button, and the proximal end wall covers said proximal end opening of said recess;e. said proximal end wall of said latch having a socket aligned with said protruding lock tongue of said lighter seat;f. a coil spring disposed within said recess of said press-down button for biasing said latch to butt against said lighter seat such that said protruding lock tongue of said lighter seat engages said socket of said latch for preventing said press-down button from being pressed down to accidentally ignite said lighter; andg. a thumb piece mounted on said top plate of said latch for facilitating the lateral sliding of said latch;h. whereby when a user intends to use said cigarette lighter, said latch can be slid laterally against the spring force of said coil spring to disengage said protruding lock tongue of said lighter seat from said socket of said latch, thereby allowing said press-down button to be pressed down and ignite said cigarette lighter, and when the user releases said press-down button, it returns upwardly while said latch is biased back by said coil spring and said protruding lock tongue of said lighter seat automatically engages with said socket of said latch again, thereby locking said press-down button.
