Abstract

The utility model relates to a safety switch for an electronic igniter. A gas cylinder, a high voltage line and a power supply are arranged in a casing, an opening of the casing is pivoted with a button, and another opening of the casing is moveable provided with a safety switch. When the button and the safety switch are pressed simultaneously, the button is butted with a pull plate of the gas cylinder to make the gas in the gas cylinder flow out of an ignition tube of the electronic igniter. One end of a conducting strip of the button is connected with a contact point of the high voltage line, and a convex post of the safety switch pushes another conducting strip arranged on another contact point of the high voltage line. The second conducting strip is connected with the other end of the first conducting strip to make the high voltage line and the power supply switched on. Consequently, a high voltage generator of the high voltage line generates an electric arc at the position of the ignition tube. The electric arc ignites the gas to achieve the ignition efficiency.

Description

The safety switch of ignition

The utility model relates to a kind of safety switch of ignition, refers to a kind of ignition that is respectively equipped with a button and safety switch on a housing especially, and this button and safety switch are pressed on time simultaneously, and this igniter can be lighted flame.

The inventor once on November 2nd, 1998 application number be No. 98248301.5 ignition utility model patent case, as depicted in figs. 1 and 2, this case mainly ties up to and is equipped with a gas cylinder 2 and a high-tension line 3 in the housing 1, wherein, this gas cylinder gas export 20 be connected with a flexible pipe 22, the end in addition of this flexible pipe 22 is connected with an ignitron 24, this housing 1 is arranged with a sleeve pipe 16 and a contact tube 14 in regular turn in contiguous these ignitron 24 places, this gas export 20 also is pivoted with an arm-tie 26, and this high-tension line 3 joins with an ignitron 24 and a power supply 4 respectively, again, be movably equipped with a part of protruding key switch 10 that is exposed to outside the housing 1 on this housing 1, but these high-tension line 3 nationalitys are pushed this key switch 10 and are conducted with power supply 4, these key switch 10 1 ends also overlap mutually with arm-tie 26 1 ends, this housing 1 is close to these key switch 10 places in addition, be movably equipped with a catch 12, this catch 12 just can prop up key switch 10 bottom surfaces, so that key switch 10 can't be pushed the danger that meets accident to prevent touch of key-press by accident switch 10 downwards when non-use.
