Description

A kind of anti-children's lighter

Technical field

The utility model relates to a kind of lighter, particularly relates to a kind of anti-children's lighter.

Background technology

Existing piezoelectric type lighter generally comprises shell, be positioned at the piezo-electric device of shell, fuel chamber and air-valve assembly thereof, shell upper end be provided with piezo-electric device in the piezoelectricity cap offset press hand, need only press during use and press hand, the piezoelectricity cap of piezo-electric device is compressed thereupon, when its compression travel reaches the igniting stroke, the hammer of piezo-electric device Yin Qinei clashes into piezo-electric crystal and discharges high voltage electric energy, and send electric spark at place, the gas outlet of air-valve assembly by the galvanic circle, and air-valve assembly discharges combustion gas this moment simultaneously under the effect of pressing hand, and combustion gas runs into electric spark and promptly realizes sparking.

Original lighter does not have safeties mostly, the operation of promptly pressing hand is unrestricted, thereby can't prevent in transportation and carry and press hand because of unexpected percussion in the process and strike sparks that also can't stop children to miss sparking because of playing, its result causes contingencies such as fire easily.So in order to improve the security of lighter, people design various safeties, its principle mainly contains two kinds:

First kind to be safeties in nature stop presses hand and make it and can't be pressed, during sparking, then move earlier in safeties, it is removed pressing the obstruction of hand, press again and press hand and can strike sparks, as the patent No. is 96245667.5 Chinese utility model " the piezoelectric type lighter of band safeties ", the patent No. is 00264032.5 the disclosed scheme that comes to this of Chinese utility model " being provided with the lighter of locking key ", this class lighter is when reality is used, the user must press in the operation safeties and press hand, and two actions must be finished with a finger, not only need cooperative ability preferably, and must operate with bigger power, thereby prevented children's mis-ignition preferably, yet, this is provided with obstacle also for simultaneously normal sparking, on the other hand, owing to be subjected to the restriction of lighter volume, the piece volumes of safeties is less, in light weight, can not have enough intensity, the user tends to be eager sparking and has forgotten first operation safeties, directly firmly push in this case and press hand, very likely lighter is caused damage, and, this situation also occurs on one's body the children easily, owing to when normal running, operate for singly referring to, therefore appearing children is directly to press (many do not have the lighter of safeties be exactly like this igniting) of pressing that hand just can light a fire, under the ordering about of curiosity, he might go into overdrive directly to press and press hand in the hope of sparking, thereby lighter is caused damage;

Second kind is that safeties directly do not stop and press being pressed of hand, but stop it to press to the igniting stroke, even piezo-electric device is not enough in lighting a fire because of the stroke of piezoelectricity cap, as the patent No. is 97210601.4 Chinese utility model patent " safe electronic lighter " a kind of scheme that comes to this, it " is equipped with a rubber-like safety locking bar; safety lock club head end face is corresponding with operating parts guide groove top end face; distance h between the two is less than the igniting stroke of igniter; when sparking; the igniter operating parts is depressed; will slide relatively in the top of safe locking bar in the guide groove of operating parts in the igniter mounting groove in body, reach h when pressing down distance, near but do not reach the igniting stroke, two corresponding end faces of operating parts guide groove top and safety lock club head contact, produce a suitable resistance, stop operating parts to continue 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 be depressed into igniter and excite the required igniting stroke of high-voltage spark, the fuel gas that the some gas valve has discharged ".It has overcome the operational deficiencies of above-mentioned first kind of lighter preferably, promptly when children in when sparking imitation, pressing hand can be pressed, but can can't strike sparks because the igniting stroke is not enough, after repeatedly attempting, children will lose interest and no longer play, and lighter is also unlikely so damage.But because the action of the normal ignition of this scheme is still with conventional consistent, just need to strengthen the dynamics that presses down, thereby can't prevent children's mistake sparking that finger power is bigger, on the other hand, its safety lock club head end face and operating parts guide groove top are after multi-pass operation, contact surface between the two can become smooth because of wearing and tearing, thereby in use for some time, the safety lock club head can diminish gradually to the resistance at operating parts guide groove top, finally make the operator need not apply bigger power and just can easy to doly light a fire, thereby lost safety effect.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of new have safeties, simple in structure, the piezoelectric type lighter that can prevent children's mis-ignition at above-mentioned prior art, when directly pressing down at the safety position of not removing safeties when pressing hand, press that hand can be pressed but can can't strike sparks less than the igniting stroke because of piezo-electric device up to pressing down also.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: these anti-children's lighter, comprise shell, be positioned at the piezo-electric device of shell, seesaw, fuel chamber and air-valve assembly thereof and windshield, be provided with in the upper end of shell and press hand, the direct piezoelectricity cap with described piezo-electric device of inwall of pressing hand offsets, perhaps pressing the inwall of hand and the free end of described seesaw offsets, the stiff end of seesaw links to each other with described air-valve assembly, the fulcrum at seesaw middle part and the piezoelectricity cap of described piezo-electric device offset, it is characterized in that: described top movable of pressing hand is provided with when pushing open outward one day described piezo-electric device is resetted fully, the safety fastener that when pressing described piezo-electric device can't be resetted fully inwardly, this safety fastener have the blocking part that a free end with described seesaw that inwardly is provided with offsets.

As improvement, described safety fastener is the L type, and is wrapped in the described portion on hand of pressing, and first end of this L type safety fastener is connected with described top movable of pressing hand, and described blocking part is arranged on the bottom of first end of this L type safety fastener; The free end of this L type safety fastener extends to the described lateral wall of pressing hand, and the free end of this L type safety fastener has a projection, and the described lateral wall of pressing hand is provided with the groove that described projection is snapped in.

Preferably, it is characterized in that: first end of described L type safety fastener and the described top of hand of pressing are for being flexible coupling.

Compared with prior art, advantage of the present utility model is: by be provided with the safety fastener that can make described piezo-electric device reset fully, when pressing described piezo-electric device can't be resetted fully when pushing open outside one day inwardly in the top movable of pressing hand, by on safety fastener, establishing the blocking part that a free end with described seesaw that inwardly is provided with offsets, when safety fastener is pushed open outwardly, piezo-electric device resets fully, can light a fire; When pressing safety fastener and pressing hand, after once striking sparks smoothly, because safety fastener is pressed inwardly to latch in and pressed on hand, piezo-electric device can't reset fully, though this moment, snap close had pressing hand and can being pressed of safety fastener, but because the stroke of piezo-electric device is not enough, can not realize sparking, have only once more safety fastener is pushed open up, just can light a fire next time, novelty simple in structure, easy to use.
