Description

Child-proof starting lighter

Technical field

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

Background technology

Only need press when existing piezoelectric lighter uses and press hand; Make the piezoelectric compression stroke reach the igniting stroke; Hammer in the piezoelectricity clashes into ceramic particle and discharges high voltage electric energy; Send electric spark through the galvanic circle at place, air valve gas outlet, and air valve is emitted combustion gas this moment simultaneously under the effect of pressing hand, combustion gas runs into electric spark and promptly realizes sparking.

For improving the security of lighter, people design various safeties, and the lighter design principle of existing band safeties is divided into following two kinds basically: a kind of is " gravity lock " principle; Promptly press hand when igniting when depressing; Press hands movement to certain stroke, can run into a bigger elastic resistance, if want normal ignition; Then need conscious increasing to pressing the pressure of hand, could normal ignition.Like the Chinese utility model patent of the patent No. 97210614.4, employing be exactly this principle.Adopt the lighter of " gravity lock " principle design, concerning the less relatively children of finger power, played the effect that is difficult to strike sparks really, but, then be difficult to reach security purpose for the relatively large children of finger power.

Another kind is that locating part or stop member are set.Normally in the process that piezo-electric device is replied, utilize locating part to stop piezo-electric device is replied not in place, during normal ignition, must elder generation lift restrictions once more, make it be returned to the normal position, just can operate once more piezo-electric device by beating the back.The lighter of locating part or stop member is set, owing to make operation sequence complicated, thereby make children's mistake get fiery difficulty increasing ready.But the complicated of its operation sequence increased trouble also for normal the use.

The utility model content

The utility model technical problem to be solved is to overcome above-mentioned prior art to have defective, and a kind of piezoelectric lighter that adopts new safeties is provided, and directly presses hand and can not be pressed and can't strike sparks by beating when pressing hand, making not removing safeties.

For this reason; The technical scheme that the utility model adopts is following: child-proof starting lighter, and comprise housing and be installed in the hand of pressing on the housing, it is characterized in that; Said top of pressing hand is provided with " L " shape switch that can vertically rotate; This switch is connected on the housing through bearing pin, forms the breach that can be used with the switch vertical part on the lateral wall of housing, and the below of switch transverse part is provided with the torsion spring that is enclosed within on the pin; One end of this torsion spring leans on the inner bottom surface of switch transverse part, and the other end leans to be pressed on hand on the surface; When torsion spring was in the normal state, the switch vertical part placed in the breach and conflict on housing in its bottom, and pressing hand can't be pressed; After switch rotated an angle, torsion spring was in confined state, and switch vertical part and breach break away from, and press hand and are in the state that can be pressed.

The utility model makes to be pressed hand and can't be pressed under normal conditions; As will normally use, must make the vertical angle of rotating of switch earlier, switch vertical part and breach disengaging meanwhile must be pressed hand and just can light a fire by beating; Decontrol after the completion to be used and press hand, under the effect of piezo-electric device, press the hand answer and put in place, switch also returns to the position under the effect of torsion spring.Press on hand because the switch of the utility model is located at, push and press hand, as long as push switch.

When children use the utility model, finger is placed on the switch, because finger is less, when pressing switch, the angle that can't make switch rotation one that switch vertical part and breach are broken away from even firmly press switch, all can't be accomplished igniting usually.Even it is bigger that indivedual children point area, also can be through increasing the coefficient of elasticity of torsion spring, make the support force of torsion spring be far longer than children's pressing force, make children still can not be completed igniting.

As preferably, be in the normal state down, described pressing forms one on hand and is lower than case top and is positioned at the step of housing, and described switch places on the step.Switch is hidden in the housing, is difficult for maloperation and does not influence the profile of lighter, little with the shape differentiation of conventional lighter, safeties are difficult for being penetrated by children.

As preferably, described pin is positioned at the inboard of the center line of switch transverse part, and the run-on point that makes switch reduces the force distance of torsion spring as far as possible near the inboard of pressing hand, increases the required power of rotating switch, increases the difficulty of children's operation.

As preferably; Be in the normal state down, the inner upper surface formation one of said switch transverse part protrudes in the protuberance of case top, and protuberance makes things convenient for the operation of adult's arming; Protuberance is located at the inner upper surface of switch transverse part; Away from the center of switch transverse part, because the contact area of children's finger is less, the difficulty that children are operated.

As preferably, the bottom of switch transverse part is circular arc, reduces the frictional force that produces when switch rotates.

The beneficial effect that the utlity model has: 1. compared with prior art; The utility model has been broken through " gravity lock " or prevention piezo-electric device answer principle not in place in the existing design; Make under the normality that pressing hand can't be pressed under the effect of switch, thereby prevent the generation of accidental ignition effectively.Therefore the more weak or little children of finger area for the coordination ability are difficult to the imitation igniting; Even the strong or big children of finger area for the coordination ability also can increase children's operation easier through the coefficient of elasticity that increases torsion spring, avoid children to accomplish igniting.2. because the igniting of the utility model action is very simple concerning the adult in operation, only need to accomplish two actions, almost do not have the sensation of complex operation, preferably resolve the operation sequence complicated problems with a finger.

Below in conjunction with the Figure of description and the specific embodiment the utility model is described further.
