Description

Safety lighter

It is the lighter of fuel with the liquefied gas that the utility model relates to a kind of, particularly is provided with the lighter of release mechanism.

For preventing children, especially young child causes burning because of the lighter improper use or the generation of fire incident, and all there is the lighter of release mechanism in many countries in development.As the lighter patent CN90110057.9 of U.S. BIC Corp., be can be provided with one and selectively move and can automatically reset safety latch at lighter and actuator (operating parts).During sparking, safety latch just can automatically reset and withstand the actuator afterbody and it can't be depressed open air valve, and lighter just can not beaten.The lighter patent CN91110840.8 of Thailand Thai Merry Co., Ltd. and for example is that locking piece is rotated and can makes on the position that operating parts moves when igniting, and the locking piece that is subjected to the spring turning effort after the igniting can not move the mobile status position to operating parts.So just when misfiring, pinned the igniting action of operating parts automatically.The release mechanism of these lighter all is to have increased a safety latch (locking piece) between operating parts and body.They must have two actions to light a fire when using.Like this, use and have a hunch loaded down with trivial details inconvenience.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, provides a kind of once to move the lighter that is provided with release mechanism of finishing igniting.

The utility model is achieved in that lighter comprises body, spark generator, air-valve device, intermediate support and valve opening device.The wiping fire wheel shaft of spark generator is made the even number polygon.It is big that the type hole width that matches with the fiery wheel shaft of wiping on the intermediate support becomes from top to bottom gradually, and its upper end width must can not rotate by the assurance wheel shaft therein, and the lower end width must guarantee that wheel shaft can rotate therein.Under normal conditions, when lighter did not use, the wiping of spark generator fire wheel was pulled to the upper end in intermediate support type hole by flint under the effect of flint spring power, wipe fiery wheel shaft and be in narrower position, type hole.At this moment, people wipe the igniting of fire wheel as habitually rotating, and then limit because of wheel shaft is subjected to intermediate support type hole, wipe fiery wheel and can not rotate, so can not light a fire.Applying a bigger downward pressure when give wiping the fire wheel consciously, making when wiping fiery wheel shaft and leaving the narrow porose area in type hole and enter wide porose area, could rotate like a cork and wipe the fire wheel and produce spark.Meanwhile, can light a fire with the same lever of pressing usually.Igniting finishes, and unclamps lever and wipes the fire wheel, and they all are returned to common position under the spring force effect.Like this, the utility model makes lighter be in safety or fired state by the sparking position that limits lighter wiping fire wheel, makes young child be difficult to grasp its ignition method, has good security.Simultaneously, concerning the adult, only need increase consciously wiping the dynamics that the fire wheel presses down, once action can be finished igniting, and is easy and simple to handle.

In addition, the utility model also has following advantage: (1) this lighter is provided with the release mechanism that obviously exposes, and for children good disguise is arranged.Lighter is lighted in the unconscious igniting action of simultaneously can avoiding again being grown up.(2) product structure is simple, needn't increase any part on former common lighter, and is easy to manufacture, easy to assembly, adapts to produce in enormous quantities.

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

With reference to Fig. 1, Fig. 2, the safety lighter is made up of body, spark generator, air-valve device, intermediate support and valve opening device.Body comprises oil storage tank 12, oil groove lid 10, hurricane globe 1 and cartridge assemblies 11.On oil groove lid 10, the air-valve device 9 that links to each other with cartridge assemblies 11 is housed.Air-valve device comprises that fire moving up and down chews pipe 7 and be enclosed within the outer adjustable ring 8 of air-valve assembly.The valve opening device be lever 4 be enclosed within fire chew the pipe 7 on.Spark generator comprises wiping fire wheel 2, flint spring 6, the flint 3 that is contained on the intermediate support 5.Intermediate support 5 is fixed on the oil groove lid 10.

With reference to Fig. 4, Fig. 5, the axle 13 of wiping fire wheel 2 is even number polygon (being quadrangle shown in the figure), and the type hole 14 of matching with the fiery wheel shaft 13 of wiping on the intermediate support 5 is designed to up-narrow and down-wide slotted hole, and lower end or two ends preferably are circular arc.It is big that the width W in type hole becomes from top to bottom gradually, and wide being slightly larger than of upper end hole wiped fiery wheel shaft opposite side distance from S, and less than wheel shaft catercorner length L, the lower end width is greater than the wheel shaft catercorner length.Guarantee to wipe the fire wheel and can not rotate, and can freely rotate in lower end, type hole in upper end, type hole.Intermediate support type hole 14 in vertical state, certain angle also can tilt.In addition, fillet preferably is processed at each angle of wiping fiery wheel shaft 13, can successfully slide into upper end, type hole so that wipe the fire wheel after having struck sparks in the lower end in intermediate support type hole.

The use of safety lighter is as follows: as shown in Figure 1, lighter is in a safe condition.Wiping fire wheel 2 is upwards headed into intermediate support 5 and wipes the position, a place, 14 upper end, type hole that fiery wheel shaft 13 matches by flint 3 by flint spring 6.The normal custom of this moment as connection is dialled changes wiping fire wheel 2, and then the width W because of a position is littler than the catercorner length L that wipes fiery wheel shaft, wipes fiery wheel shaft 13 can not rotate in the type hole, so the fiery wheel of wiping can not produce spark with the flint relative motion.Even hand was pinned lever 4 and mentioned fire and chew pipe 7 and open air valves and overflow combustion gas this moment, also can not catch fire.As shown in Figure 3,, only need pin and wipe fire wheel 2, to pressing down,, wipe the 14a place, type hole that fiery wheel shaft 13 leaves intermediate support 5 consciously, enter position, b place by flint 3 compression flint springs 6 if when needing with fire.The type hole width W of b place is greater than wiping fiery wheel shaft catercorner length L.The fire wheel is wiped in this moment as group commentaries on classics, then can rotate like a cork, with flint 3 relative motions generation spark.At this moment the lever 4 of pressing as usual is mentioned fire and is chewed pipe 7 and open air valves, and the combustion gas of overflowing is caught fire by spark ignition.With fire intact after, openhandedly open lever 4 and wipe fire wheel 2, lever 4 resets under the spring force effect of air-valve device; Wiping fire wheel then under the restoring force effect of flint spring 6, upwards pushes up it by flint 3, makes wiping fire wheel 2 be returned to original home a place.
