An electronic lighter with locking device comprises a gas storage chamber (13), a piezoelectric unit (15) and a gas outlet assembly (16) above the chamber. The piezoelectric unit includes a snapper (8) and a piezoelectric chunk (11). The gas outlet assembly (16) includes a pry plate (2) and a gas outlet valve (3). A slot (9) is made on the snapper (8), which has a circular open groove (92) at its end. A swinging button (7) is provided inside the slot (9), which is able to rotate and equipped with a long arm (72) that is able to rotate around the open groove (92). The piezoelectric chunk has a protrusion (111). When lighter is at a locking position, the button (7) is not allowed to move downward because its long arm (72) is located above the protrusion (111). For assuring the safety of lighter and preventing from incorrect operation, combined with the snapper, a locking mechanism is provided in this invention. If the swing button is at a locking position, the piezoelectric chunk will not produce electronic current to make a spark, and the inflammable gas cannot escape from the gas outlet even though pressing the snapper.
