For prevent children especially young child cause burning because of the lighter improper use or the generation of fire incident, the many countries such as the U.S., Canada, Australia and each state of Europe have stipulated that all the lighter of selling in its market all must be provided with release mechanism, to prevent the generation of similar accident.In recent years, the ratio of electronic lighter institute's certificate in lighter gang is increasing, and the electronic lighter that development has release mechanism has become the manufacturing main target of lighter.

The purpose of this utility model provides a kind of not only safe in utilization but also easy to operate electronic lighter with new type of safe mechanism.

The utility model is realized in the following way: this electronic lighter comprises body, igniter, air-valve device.Be provided with a guide groove from top to bottom in the back skirt section of igniter operating parts.A rubber-like safety locking bar is housed in the igniter mounting groove in body.Safety lock club head end face is corresponding with operating parts guide groove top end face, and distance h between the two is less than the igniting stroke of igniter.The utility model has utilized the characteristic of piezoelectric ignition system device, during igniting, the operating parts of igniter must be depressed into the igniting stroke from top to bottom, just can make an energy abrupt release that impact spring is stored in the igniter in compression process, piezo-electric crystal produces and impacts relatively, cause the high voltage electric energy that is stored in the piezo-electric crystal and discharge, by conductor circuit the fire on the air-valve device is chewed the pipe gas outlet and cause high-voltage spark, lighter is lighted.The distance that presses down as operating parts does not reach the igniting stroke, and the impact spring of igniter just can not produce impact at the energy that this section compression process is stored, and makes operating parts return to the elastic force of origin-location and only can become.Owing in the utility model, be provided with above-mentioned release mechanism, during igniting, the igniter operating parts to be depressed, will slide in the guide groove of operating parts relatively in the top of safe locking bar.Reach h when pressing down distance, near but when not reaching the igniting stroke, two corresponding end faces of operating parts guide groove top and safety lock club head contact, and produce a suitable resistance, the prevention operating parts continues to move downward.This moment, igniter also can not excite high-voltage spark that lighter is lighted.Have only and continue consciously at this moment to apply bigger pressure to operating parts, operating parts guide groove top end face acts on safety lock club head end face, component on its horizontal direction will force safe locking bar to produce strain, operating parts just can continue to press down and reaches igniter and excite the required igniting stroke of high-voltage spark, the fuel gas that the some gas valve has discharged.Therefore children are when especially young child is plaied with fire, press down when being subjected to resistance at operating parts, or because of can not continuing consciously firmly operating parts to be depressed, or because of there not being enough strength to overcome the resistance of two opposing end surfaces generations, all lighter can't be lighted usually.After the adult has put fire, can get back to initial position automatically under the effect of operating parts back-moving spring elastic force in igniter, safe locking bar is also got back to initial position automatically under the screen resilience effect of himself, thereby guarantees the security performance of lighter.

The utility model compared with prior art has more following advantages,

1, security performance is good.The release mechanism that this lighter does not obviously expose has good disguise for children, and can prevent electronic lighter and producing, transporting and carry accidental collision impact in the process and the danger of lighting lighter.

2, easy to operate.During operation, do not have to change the habitual movement of operating electronic lighter before, only need increase the pressing action dynamics consciously.

3, whole release mechanism only increases a part, transforms a part, and is simple in structure, easy to manufacture, easy to assembly, adapts to produce in enormous quantities.

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

With reference to Fig. 1, Fig. 2, Fig. 3, the utility model is made up of body, air-valve device, igniter and safe locking bar 9.Body comprises oil storage tank 10, oil groove bottom 11, hurricane globe 5 and mounting bracket 2.Air-valve device comprises valve component 3, drainage core assembly 1, adjustable ring 4, opens element 7.Igniter comprises operating parts 8, engine firewall 13, lead 25, pressing plate 14, interior cover 15, impact spring 17, horizontal door bolt 19, hammer 24, back-moving spring 23, overcoat 20, piezoelectric crystal component 21 and anvil 22.The back skirt section of operating parts 8 has a guide groove 12 from top to bottom, and guide groove top end face is inclined-plane or cambered surface 16.Safe locking bar 9 is installed in the mounting groove of igniter in the body.Safe locking bar 9 is made by the good elastomeric material of intensity, and its underpart is fixed on the body.Safe locking bar 9 top end faces are inclined-plane or the cambered surface 18 relative with inclined-plane, guide groove top or cambered surface 16, and spacing distance between the two is h.The utility model has utilized piezoelectric crystal component 21 to be the intrinsic architectural characteristic of the igniter of core largely.In the pressing down of operating parts 8.Cover 15 has produced relative motion in making in overcoat 20.When this movement travel reaches igniter setting igniting stroke, horizontal door bolt 19 can lose the control of counter-blow hammer 24, the energy abrupt release that impact spring 17 is stored in this compression process, allowing 23 pairs of piezoelectric crystal components of hammer 21 produce impacts, the high voltage electric energy abrupt release that makes in the piezo-electric crystal to be stored, chew 6 two ports that close on mutually by conductor circuit giving vent to anger in lead 25 and air-valve assembly 3 and produce electric sparks, be used for igniting.Meanwhile, back-moving spring 23 also is compressed, and loses external force at operating parts 8 and does the time spent, and its screen resilience just makes horizontal door bolt 19, hammer 24, press-working spring 17, interior cover 15, pressing plate 14, operating parts 8 get back to initial position.Igniter is got back to original state, if operating parts 8, under the effect of external force, depression distance is less than the igniting stroke, the energy of being stored in the impact spring compression process will can not discharge owing to the control of horizontal door bolt 19, and cover 15, pressure 14, operating parts 8 recover the elastic force of initial positions in only can becoming, make whole igniter get back to original state together with the elastic force of back-moving spring 23, can not reach the igniting purpose.

With reference to Fig. 4, the inclined-plane of the inclined-plane at operating parts guide groove top or cambered surface 16 and safety lock club head or cambered surface 18 keep a spacer segment distance h.With reference to Fig. 5, during igniting, operating parts 8 moves downward under the effect of external force, and safe locking bar 9 first halfs just slide in guide groove 12, and when distance reached h, two corresponding inclined-planes or cambered surface 16 and inclined-plane or cambered surface 18 contacted.To operating parts 8 move downward the generation resistance, though this moment is by pressing plate 14, to opening the element 7 one end application of forces, air-valve device is opened, given vent to anger and chew 6 and begin venting, but because the stroke that operating parts 8 is depressed does not reach the igniting stroke, igniter can not produce spark, and lighter can't be lighted.With reference to Fig. 6, if will continue operating parts is pressed down, must impose bigger strength to operating parts 8 consciously, overcome two resistances that contact-making surface produced this moment, make 16 pairs of inclined-planes of inclined-plane or cambered surface or cambered surface 18 component in the horizontal direction, can force safe locking bar 9 to be out of shape left, the pressing down stroke and can reach or be slightly larger than the igniting stroke of operating parts 8, igniter just can be given vent to anger at air valve and be chewed a mouthful end generation spark this moment, and the fuel gas that discharges is thus lighted.After having put fire, unclamp operation part 8, operating parts 8 just can be got back to original state shown in Figure 4 under the effect of back-moving spring 23 screen resiliences.Safe locking bar also can be got back to original state by the elastic force of himself.
