Description

The safe electronic lighter

It is fuel with the liquid gas that the utility model relates to a kind of, with the electronic lighter of piezoelectric ignition system, particularly is provided with the electronic lighter of release mechanism.

For prevent children especially young child cause the generation of fire incident because of the lighter improper use, the many countries such as the U.S., Canada, Australia and each state of Europe have all successively stipulated that the lighter of its market sale 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.Top and skirt section, back at the igniter operating parts have slotted eye.The rubber-like safety locking bar of in the slotted eye of operating parts top, packing into.Safe locking bar top has guide groove to match with operating parts top slotted eye and can slide along the horizontal direction of slotted eye.Safe locking bar middle part has boss to pass behind the operating parts outside the slotted eye of skirt section.During the lighter igniting, igniter must be depressed into the igniting stroke from top to bottom through operation, the energy that impact spring in the igniter is stored in compression process discharges, piezo-electric crystal produces and impacts relatively, causing the high voltage electric energy that is stored in the piezo-electric crystal discharges, by conductor circuit giving vent to anger on the air-valve device chewed the gas outlet and cause high-voltage spark, lighter is lighted.Because the utility model is provided with above-mentioned safety device, when connecting the reason condition habitually during the igniting of push spare, because of propped up the oil storage tank top edge of body in the middle part of the safety locking bar to the boss of outer process, limited the downward movement of operating parts, can not be by down-firing.Only deposit instantly by before the operating parts igniting, the safety lock club head that will be contained in earlier consciously on the operating parts inwardly pushes away a segment distance along operating parts top slotted eye, makes the correspondingly direction motion in body of boss at safe locking bar middle part, and boss gets out of the way the body top edge.At this moment, but just push spare is descending up to the piezoelectric ignition system stroke, and the piezo-electric crystal discharge produces the fuel gas that the spark ignition air valve has discharged.Therefore, children do not have the action of above-mentioned " consciously ", so lighter can not be lighted when especially young child is played this lighter.After having put fire, operating parts under the effect of back-moving spring elastic force, is got back to initial position automatically in igniter; Safe locking bar also is operated part and brings back to initial position, thereby guarantees the security performance of lighter.

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

1, security performance is good.Not only children there is good security, and can avoids electronic lighter to be lighted producing, transport and carry in the process once in a while collision impact.

2, simple to operate.This lighter operation change operating habit of electronic lighter in the past only need increase an action consciously and get final product.

3, easily manufactured.Whole release mechanism has only increased a part on primary electron lighter basis, simple in structure, adapts to produce in enormous quantities.

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

Fig. 1 is structural representation of the present utility model (being in initial position);

Fig. 2 is Fig. 1 right view;

Fig. 3 is the utility model igniter part-structure schematic diagram;

Fig. 4 is that the boss of the utility model safety locking bar leaves body top edge view;

Fig. 5 is the schematic diagram that the utility model is in ignition location.

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.Body comprises oil storage tank 10, hurricane globe 5 and support 2; Air-valve device comprises valve component 3, drainage core assembly 1, and flame adjusting ring 4, air valve are opened no part 7.Igniter comprises operating parts 8, engine firewall 13, lead 12, pressing plate 11, interior cover 14, impact spring 15, horizontal door bolt 16, hammer 17, back-moving spring 18, overcoat 19, piezo-electric crystal 20 and anvil 21.The top of operating parts 8 and skirt section, back respectively have a slotted eye 8A and 8B.Safe locking bar 9 is made by the good elastomeric material of intensity, and its top has guide groove 9E to match with the width of operating parts top slotted eye 8A, joins together with operating parts, can slide at the length direction of operating parts top slotted eye 8A after its chute 9E is stressed.Safe locking bar 9 middle parts have a boss 9A to pass the back skirt section slotted eye 8B of operating parts.Boss 9A is parallel to the glide direction of guide groove 9E, and its outwards outstanding height surpasses the inwall of body oil storage tank 10 and less than the length of slotted eye 8A.Instantly during press operation spare 8, boss 9A just props up oil storage tank 10 top edges, stops operating parts to move downward.For making safe locking bar in inactive state and motion process certain stability be arranged all, the bottom of safe locking bar 9 becomes Elastic Contact with overcoat 19 outer walls of the oil storage tank of body 10 inwalls and igniter.Present embodiment curves S shape (9B-9C-9D among the figure) with safe locking bar 9 bottoms, makes it easily stably to slide up and down.

During igniting, light a fire as habitually press down operating parts 8, then propped up the top edge of body oil storage tank 10 because of safety locking bar boss 9A, operating parts 8 can not descending (as Fig. 1).With reference to Fig. 2, Fig. 4, when before pressing operating parts down, earlier inwardly apply some thrust consciously at the safety lock masthead portion 9F place that protrudes in plane on the operating parts, safe locking bar upper guide groove 9E is moved inward along operating parts top slotted eye 8A, simultaneously, corresponding the following in safe locking bar middle part moves inward, and at this moment, safe locking bar boss 9A has just left the top edge of body oil storage tank 10.With reference to Fig. 3, Fig. 5, if this moment, press operating parts 8 down, interior cover 14 just produces in overcoat 19 and moves downward relatively, safe locking bar bottom 9C, the 9D point is then along overcoat 19 outer walls that cooperate with it, body oil storage tank 10 inwalls are to lower slider, when movement travel reaches the igniting stroke of igniter setting, the same with the ordinary electronic lighter, horizontal door bolt 16 has just lost the control of counter-blow hammer 17, the energy abrupt release that impact spring 15 is stored in compression process, allowing 17 pairs of piezo-electric crystals of hammer 20 produce impacts, the high voltage electric energy abrupt release that makes in the piezo-electric crystal to be stored is chewed 6 two ports that close on mutually by galvanic circle giving vent to anger in lead 12 and valve component 3 and is produced electric sparks.With it simultaneously, in the descending process of operating parts 8, the pressing plate 11 that is mounted in it has been pushed down the rear end of opening element 7, because the point action of support 2, the front end of opening element 7 has been mentioned to give vent to anger and is chewed 6 and opened air valve, and the electric spark that fuel gas is chewed port by gas kindles a fire.After having put fire, get back to original position under the effect of back-moving spring 18 screen resiliences that unclamp operation part 8, operating parts just can be in igniters.Simultaneously, safe locking bar 9 bottom 9C, 9D are along with operating parts 8 resets, and along outer casing outer wall, the body inwall upwards slides into original position; Top, middle part also reset under the effect of part self elastic force, skirt section, the boss 9A at middle part outstanding again operating parts 8 back slotted eye; Air valve is then closed under self intrasystem spring force effect.
