现有技术中的按压式电子打火机包括机壳、 头盖、 燃气箱、 压电装置、 导气芯装置、 导气管和跷板。 当旋转打开头盖时， 头盖压下压电装置， 使压电装置产生火花， 进而点燃' 气体，产生火焰。 由于这种结构的打开头盖动作和点火动作是同时进行的， 即只要打开头 盖， 就会产生火焰， 因此容易因误压头盖， 而导致自动点火， 最终酿成火灾。此外， 儿童 的盲目玩弄， 也极易发生事故。 发明内容  The push-type electronic lighter in the prior art includes a casing, a head cover, a gas tank, a piezoelectric device, a gas core device, an air tube and a seesaw. When the head cover is rotated and opened, the head cover depresses the piezoelectric device, so that the piezoelectric device generates a spark, which in turn ignites the gas and generates a flame. Because the opening of the head cover and the ignition operation of this structure are performed simultaneously, that is, as long as the head cover is opened, a flame will be generated, so it is easy to cause automatic ignition by accidentally pressing the head cover and eventually cause a fire. In addition, children's blind play is also prone to accidents. Summary of the Invention

At this time, only When it is necessary to ignite consciously, press the head cover vertically downwards, so that the pins in the horizontal position move downward along the elongated holes in the gas tank (and the middle frame), so as to depress the piezoelectric device and generate a flame. This prevents fires caused by unintentional auto-ignition. In addition, because a strong spring is installed in the piezoelectric device, the force required for piezoelectric ignition is increased, making it difficult for children to press the piezoelectric device with sufficient finger force even when the head cover is opened. This can eliminate accidents.
