Abstract

The utility model relates to an electronic lighter capable of preventing error ignition, which comprises a casing with a gas storing chamber, a piezoelectric device, an outer head, a gas outlet valve, a flame nozzle, a press cover and a prizng board. The utility model is characterized in that a safety device preventing the press cover from pressing downward is arranged between the outer head and the press cover, wherein the safety device comprises a lock sheet of the press cover and a slide sheet, and the lock sheet of the press cover is arranged to be an elastic strip-shaped body. One end of the lock sheet of the press cover is fixedly connected with the upper part of the press cover, and the other end of the lock sheet of the press cover extends downward. The upper part of the outer side of the lock sheet of the press cover, which is corresponding to the outer head, is provided with a protrusion preventing the press cover from pressing downward and the slide sheet can be sheathed on the lock sheet of the press cover in an upward and downward slide mode. When the slide sheet slides upward and downward, the lock sheet of the press cover can elastically deform outward or inward. When the utility model is used, the slide sheet only needs to be poked downward to enable the lock sheet of the press cover to deform elastically. Therefore, the protrusion on the lock sheet of the press cover is disengaged from the stop of the outer head and the press cover can be pressed to realize ignition. The utility model has the advantage of simple and skillful structure, and on the basis of ensuring safety, use is more convenient.

Description

A kind of electronic lighter of anti-error sparking

Technical field

The utility model relates to a kind of lighter, specifically is a kind of safeties that have, and can prevent that children mistake strikes sparks or prevent in transportation and carry the electronic lighter of striking sparks because of unexpected percussion gland in the process.

Background technology

In order to improve the security of electronic lighter, prevent from transporting and carrying in the process and strike sparks because of unexpected percussion gland, or prevent that children from causing contingencies such as fire because of the electronic lighter of playing misses sparking, generally all is provided with safeties on electronic lighter.In the prior art, a kind of lighter is arranged, as the China Patent No. ZL 00264032.5 disclosed lighter that is provided with locking key, its structure comprises oil groove, is positioned at the piezoelectric device of oil groove, goes out pneumatic module, wherein piezoelectric device comprises and presses hand, piezoelectricity cap, piezoelectric blocks, go out pneumatic module and comprise air outlet valve and skid plate, it is characterized in that pressing and be provided with one between hand and the piezoelectric blocks and be "T"-shaped locking key, at locking key and press and be provided with a back-moving spring between the hand, the lower end of the montant of locking key and the left side of piezoelectric blocks or right side are inconsistent.When using, promote locking key, make locking key break away from the piezoelectric blocks upper end, push again and press hand and could strike sparks, after igniting finishes, back-moving spring resets locking key, recover lock-out state, though the safeties of the lighter of this structure can prevent maloperation, the security performance of lighter is increased, but these safeties still exist complex structure, problem that production cost is high, and must promote locking key simultaneously and implement push action with finger when using, might attend to one thing and lose sight of another like this, comparison inconvenience seems.

Summary of the invention

The purpose of this utility model is at above-mentioned existing problems and deficiency, and a kind of electronic lighter of guaranteeing to use on the safe basis more convenient anti-error sparking is provided.

The technical solution of the utility model is achieved in that

A kind of electronic lighter of anti-error sparking, comprise the casing that has gas dome, piezo-electric device, outer head, air outlet valve, fire is chewed and gland, wherein, be provided with skid plate between described air outlet valve and the gland, but the piezoelectricity pedestal of electronics is housed in described piezo-electric device comprises and is installed in the piezoelectric bar that elasticity is wherein pushed, described gland and piezoelectric bar upper surface are inconsistent, its characteristics are: be provided with the safeties that can stop that gland presses down between described gland and the outer head, described safeties comprise gland locking plate and slide, according to the dovetail groove principle, the gland locking plate is set to an end and fixedlys connected with the top of gland, the elasticity strip shape body that the other end extends downwards, the outer top, head position of the outside correspondence of gland locking plate is provided with the projection that can stop that gland presses down, described slide can slide up and down and be nested with on the gland locking plate, and can make the gland locking plate outwards or inwardly do the strain action when slide slides up and down.

In order to stop that effectively gland presses down, the top of above-mentioned projection is set to acclivitous inclined-plane, and the top of projection is set to the plane, and the bottom of projection is set to block the right angle face that outer head side top stops that gland moves down.For making slide effectively control gland locking plate strain, be provided with the space between above-mentioned gland locking plate and the gland two side, slide is provided with the mesopore that can be placed on the gland locking plate, and the slide both sides are provided with the movable gathering sill that clamps on the gland two side.

The utility model is owing to adopted the safeties that setting is made up of gland locking plate and slide between gland and outer head, the outer top, head position of the outside correspondence of gland locking plate is provided with the projection that can stop that gland presses down, slide can slide up and down and be nested with on the gland locking plate, and when sliding up and down, slide can make the gland locking plate outwards or inwardly make the version of strain action, simple and ingenious structure, production cost is low, need only be earlier during use slide be set aside and make the gland locking plate inwardly make strain to break away from outer head and stop, implementing to push the gland mode again strikes sparks, step is simply clear and definite, use more convenient, avoided lighter when sparking of original structure must finger to promote locking key simultaneously and implement the problem of attending to one thing and lose sight of another that push action may occur to take place, in the time will stopping working, unclamp the finger of pushing gland, gland resilience under the effect of the screen resilience of piezoelectric bar, simultaneously, because under the effect of gland locking plate back-off and gland locking plate sprung back power, drive slide and also up move, so just be returned to the nature of locking lighter.Simultaneously because slide has also improved the intensity of gland locking plate according to the structure setting of dovetail groove principle, prevent that effectively children from adopting bigger strength to push gland and cause the physical damage of safeties.The utility model electronic lighter can prevent effectively that children mistake from striking sparks or prevent in transportation and carry in the process and strike sparks because of unexpected percussion gland, and is safe and convenient to use.

Below in conjunction with accompanying drawing the utility model is further described.
