安全型打火机 技术领域 TECHNICAL FIELD
本发明涉及一种按压式电子打火机, 特别涉及一种安全型打火机。 技术背景 The invention relates to a push-type electronic lighter, in particular to a safety type lighter. technical background
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

在所述的安全型打火机中, 所述中架上设置限制头盖旋转开启的挡块。 In the safety type lighter, a strong spring is installed in the piezoelectric device. '' According to another aspect of the present invention, a safety type lighter is provided, which includes a casing with an open upper end, a middle frame fixedly installed on one side of the open end of the casing, and a gas tank installed in the casing. , A piezoelectric device, a gas core device, an ignition port and a seesaw, and a head cover that is relatively rotatably mounted on the upper end of the gas tank. In addition, it also includes an elongated hole in the upper part of the gas tank, and an elongated hole is also provided in the middle frame corresponding to the elongated hole in the gas tank; a vertical integrally formed inside the top of the head cover The extended guide plate is provided with a horizontal pin at the lower end of the guide plate, and the horizontal pin passes through the elongated hole in the gas tank and the middle frame.

本发明的优点是, 开启打火机点火时, 头盖旋转碰到燃气箱或中架上的挡块后, 不能继续转动,.从而限制了头盖对压电装置作的压电动作, 此时只有在有意识地需 要点火时, 垂直往下按压头盖, 使处于水平位置的销子沿燃气箱 (及中架) 上的长 条形孔作向下运动, 才能压下压电装置, 产生火焰。 这样一来, 可防范无意识的自 动点火引起的火灾。 此外, 由于在压电装置里安装了一强力弹簧, 因此加大了压电 点火所需要的力, 使儿童即使在打开头盖的情况下, 也难以有足够的指力压下压电 装置, 从而可消除意外事故发生。 The invention has the advantage that when the lighter is turned on and ignited, the head cover cannot continue to rotate after hitting the stopper on the gas tank or the middle frame, thereby limiting the piezoelectric action of the head cover to the piezoelectric device. 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.
