Description

  The present invention relates to an improved structure of a kind of lighter safety device, and in particular, a kind of safety protection device is attached, and relates to a safety device for ignition due to unexpected collision.

  There are many types of lighter ignition systems known in the art. What is often seen is the rotation of the tooth form, which rubs the ignition stone to form a spark, ignites and releases gas (butane), and forms a flame. In another method, a piezoelectric element (a kind of transistor) is struck by a hammer to generate an electric spark, and a gas is ignited and released to form a flame.

  Since the lighter products of the above two types of ignition systems are not equipped with a safety device for the erroneous operation of the ignition mechanism, ignition due to unexpected collision is often found. For this reason, there is no influence on the convenience of use, and it is an issue for manufacturers to prevent the risk of ignition due to unexpected collision of the lighter.
