Abstract

An anti-children lever type safety lighter comprises a completely covered break-wind which covers the whole head of the body. A slot, the top of which is narrower than the lower, is arranged on the side face of the break-wind, and a step is formed at a juncture. An end of a lever type pressing handle is hinged in a housing, while the other end of the pressing handle is exposed out of the housing after drilling through the slot, and a pivot, which presses on a piezoelectric cap, is arranged at the middle of the pressing handle. Moreover, the pressing handle trends to the step side all the time. When being reset upward along with the piezoelectric device after igniting, the pressing handle is clipped under the step, so that the pressing handle cannot be fully reset upward. For the fully reset of the pressing handle is prevented, the ignition cannot be carried out even when the pressing handle is pressed, and when in normal ignition, the operation can be carried out by horizontally pushing the pressing handle and fully resetting the pressing handle and the piezoelectric cap. Because the ignition action has to be finished successively, the ignition is hardly to be imitated by a child, who shall lose the interest after pressing the pressing handle as per the regular action for a plurality of times, so that the accidental ignition can be effectively prevented.

Description

A kind of anti-children's lever type safety lighter

Technical field

The utility model relates to a kind of lighter, especially refers to a kind of piezoelectric type lighter that has safeties, can prevent children's mis-ignition.

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.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of new piezoelectric type lighter that has safeties, can prevent children's mis-ignition is provided at above-mentioned prior art present situation, 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 lever type safety lighter 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, it is characterized in that described windshield is a full-enclosed, cover the whole head of body, be provided with a slit in the windshield side, the top of this slit is narrower than its underpart, and form a step at intersection, the described hand of pressing is a lever, the one end is in the enclosure hinged, its other end passes described slit and is exposed to outside the housing as the operating position, its middle part has a fulcrum and is pressed on the piezoelectricity cap, and this is pressed hand and is assembled into the trend with step one side of being partial to slit all the time, when after igniting use to finish, pressing hand and upwards resetting along with resetting of piezo-electric device, press under the step that hand is stuck in elongated slot, and it can't fully upwards be resetted.

Compared with prior art, the utility model has been broken through to stop in original design to press subordinate pressure or stop and has been pressed the principle that subordinate is depressed into the igniting stroke, propose in a creative way to stop to press the principle that hand resets fully, make that press hand just can't reach the igniting stroke next time when being pressed, the piezoelectricity cap of compressed thereupon piezo-electric device does not just reach the igniting stroke naturally yet, can't strike sparks, thereby prevent unexpected generation of striking sparks effectively.And to realize normal ignition, then press press hand before, must laterally promote to press hand earlier, remove windshield to pressing the spacing of hand, make and press hand and piezo-electric device and fully upwards reply and put in place, press down this moment again presses hand on earth, and the compression travel of the piezoelectricity cap of piezo-electric device will have enough igniting strokes as prior art, thereby makes the piezo-electric device normal ignition.Because igniting action of the present utility model needs one one afterwards to finish two different actions earlier, therefore for the more weak children of the coordination ability, be difficult to the imitation igniting, and children press hand and after can't lighting a fire all the time repeatedly directly pressing down with the routine action, can lose interest to this, no longer play; Simultaneously, in case, can not cause damage to lighter even the adult presses hand to pressing directly to press under the spacing situation of hand not removing in use yet.
