Description

A kind of safety lighter

Technical field

The utility model relates to a kind of lighter, detailed is the safety lighter that a kind of children of preventing operate sparking, it is simple in structure, elegant in appearance, be to utilize a dome portion to be sheathed on this flint wheel both sides, and the height of this dome portion is a little more than this friction pulley, to realize that people contact this dome portion earlier, further contacting this friction pulley again could strike sparks, and belongs to economical and practical igniter product.

Background technology

The wheeled lighter of known traditional friction, it has simple in structure, operation easily, and the characteristic that production cost is low, but this characteristic has serious potential safety hazard, wherein outstanding is the phenomenon that children play with lighter, to this phenomenon, European Union makes the CR rules and carries out mandatory provision, particular content is defined on the lighter must be installed on a safety lock, can prevent that children from playing with, reduce the purpose of sparking smoothly, be that further requirement is done in the security of lighter, but this regulation is beyond doubt to the most direct influence of wheeled lighter that rubs, because the maximum characteristics of such lighter are that friction pulley exposes, being convenient for people to point direct contact rotates, produce spark by its friction flint, lighting hydraulic pressure gas lights a fire, no matter wherein the weak point that exposes of this friction pulley is it is adult or child, can contact and order about rotation easily, mean, child can utilize this lighter to strike sparks, this has caused the generation of fire incident with regard to as easy as rolling off a log, in view of the above, manufacturer produces safety lighter miscellaneous one after another, comprising the lighter that has safety device, when described safety device is that mainly people strike sparks, this safety device of operation just can be struck sparks earlier, but for the production aspect, increase production cost beyond doubt, also increase simultaneously the complexity of its operation, even, also need the guide operation of specification for the comparatively complicated lighter of some safety devices, this causes the inconvenience of numerous people and producer, but is the matter of great urgency that must solve.

Moreover, use another problem of such wheeled lighter that rubs to be that people will play twice fire at least, just can light hydraulic pressure gas, that is to say, people's finger position need rotate at least twice friction pulley, reason is that the stroke of this friction pulley is short, there are gap the time of its friction spark that flint produces and the time that hydraulic pressure gas is discharged, cause spark to burn, finger just touches the outgas valve and discharges hydraulic pressure gas, thereby can not light a fire, and just need carry out secondary action, and on primary basis, owing to an amount of hydraulic pressure gas is arranged near friction pulley, forms certain combustion-supporting condition, as people when pivoting friction is taken turns again, spark can be lighted this hydraulic pressure gas this moment, realizes igniting.According to this twice sparking action, not only can increase the consumption of hydraulic pressure gas and flint, more be the problem of number of operations, because when gas release has contacted gap with the spark amount, its spark amount is more little, just need sparking repeatedly, perhaps improve the speed of finger pivoting friction wheel, just can finish igniting, therefore, for increasing friction pulley and the flint friction spark stroke that produces, then help once to finish the sparking action, that is to say, prolong the time of staying of spark, remain on and just can light the hydraulic pressure gas that is discharged before spark does not also extinguish, this just effectively reduces the consume of additional energy source, to guarantee the sparking quality.

Therefore, the consumer also appeals to have a kind of simple to operate, and safety again, can realize that more the lighter of once lighting a fire occurs, and for manufacturer, more is to reduce production costs and improves the security performance of lighter.

Summary of the invention

The utility model is to provide a kind of safety lighter, and its main purpose is simple in structure, and the safety device that does not need any complexity additionally is set is assisted, and also can realize the result of anti-children's operation, to avoid extra extra production to this safety device.

The utility model is to provide a kind of safety lighter, and its another purpose is to increase the stroke of lighter, to prolong the time of staying of spark, realizes that spark has the enough time to light hydraulic pressure gas.

Therefore, the utility model provides a kind of safety lighter, and it comprises:

One casing, it comprises a main body section and a cradle portion, wherein this cradle portion is positioned at the position, upper end of this main body section relatively, and supports this ignition device and this outgas device by this cradle portion;

One shell, it is the upper end that is positioned at this cradle portion, and be connected in this cradle portion, and this shell has an inner surface and an outer surface, nationality is made of the preset shape of this shell with this outer surface this inner surface, and by this cradle portion of EDGE CONTACT under the inner surface, this outer surface then is provided with an opening by this shell shape, the dual-side upper limb place of this opening is provided with a dome portion, and be clamped on this locating rack by the dome portion of these opening both sides, and the other end of this opening is a paralell, and is connected in this dome portion and forms an oblique platform shape.

Wherein, edge height outside this dome portion a little more than this friction pulley, and then makes this dome portion clamping in this friction pulley dual-side.

Wherein, the oblique angle of this paralell extends to this dome portion, and is placed earlier for finger by this paralell.

Wherein the paralell that this shell had is a horizontal shape, and it is to reduce the height of this shell.

Wherein this dome portion is arranged at this cradle portion, and with the top ends of this locating rack with the shape that fuses.

Therefore, the beneficial effects of the utility model are to utilize this dome portion a little more than this friction pulley, and effectively intercept children's finger touches to this friction pulley, to be difficult to the purpose of igniting, to define simultaneously, the obstruct of having only enough pressure to overcome this dome portion could be taken turns in contact friction, and, utilize this paralell and place, thereby prolong contacting of finger and friction pulley, prolong the sparking stroke of this friction pulley generation spark for finger position.
