Description

A kind of lighter with safety ignitor

Technical field

The utility model relates to a kind of disposable lighter with safety ignitor, and it has increased the mechanism of unexpected user's operation easier, more particularly, can prevent that children from unnecessarily using lighter.

Background technology

At present, the igniter of the lighter of selling on the market mostly is direct spark ignition type, particularly disposable lighter, even underage child also can be lighted easily, this has caused certain hidden danger to property loss and personal injury.Nowadays, many countries all pay much attention to the protection to children's safety, particularly America and Europe and wait some developed countries.Safety requirements to lighter is no exception, and now, U.S. government and U.S. consumer products safety association require each cigarette lighter to comprise that disposable lighter all need be equipped with safety device, unexpected or unnecessary light and prevents that children from lighting preventing.

As everyone knows, disposable lighter is very common, and price is also quite cheap, is impossible if be equipped with expensive and complicated safety device, because this will improve the cost of disposable lighter greatly.For the production cost that the disposable lighter of safety device is housed is reduced to minimum, one of prevailing disposable safe lighter is a driving wheel type disposable safe lighter.This disposable lighter comprises a cover drive wheel spark wheel and normally rotates the generation spark, thereby reaches the purpose of lighting.Its spark wheel must could be lighted a fire after the rotation of two drive wheel, and when driving wheel and spark wheel did not have physical property and contact, driving wheel dallied usually, so just can prevent that lighter is by unintended ignition.

General known simple type lighter comprises fuselage; head; on head, be provided with nozzles; fire ring; fan housing; bridge plate; spring; flint; support and sparking wheels; the spark wheel of sparking wheels; cincture is fixed together by axis; rotate simultaneously; stop simultaneously; and cincture is higher slightly than spark wheel; when the user can rotate spark wheel and cincture simultaneously with general strength; make spark wheel and flint that friction take place and produce spark; to discharge fuel if press down pressing plate simultaneously; can reach the purpose of lighting lighter, this type of simple and easy lighter can not prevent effectively that children from playing or because of the unintentional rotation spark wheel; cincture produces that spark causes lighting lighter and all kinds of danger that take place.

Be safe handling, prevent the danger that the mistake combustion produces, previous various corrective measures are concluded following several:

1, uses such lighter in order to limit underage child, need to increase the operation easier of general lighter.For this consideration U.S. Pat 7004750B2, each has openly described a characteristic that prevents that underage child from using, and all is the relieving mechanism by hindering gaseous fuel and presses down relieving ring and prevent lighter work.

This is equipped with the disposable lighter of safety ignitor, comprise the flint that two knee walls and the position between two knee walls are supported by a spring, make it to be adapted to rotatable igniter between two knee walls, the outer round surface of spark wheel has many teeth flint that rubs to produce spark.

The driven wheel element is the coaxial spark wheel that is wrapped between two support walls, each driving wheel comprises a driving wheel and a support footpath that outer round surface is arranged, these two are supported on the sizes of footpath forr a short time than two gears, and axis direction is mounted on the both sides of spark wheel to show two support breach between spark wheel both sides and two gears.And these two gears are assemblied in two knee walls by rotatable respectively, and spark wheel just can be driven in rotation when two gears are driven in rotation.

Each drives the interior abutment wall that cap comprises a driving ring and extends from the driving ring circumferential edges, each driving ring has a level and smooth outer round surface, an internal circular surfaces and a driving ring inner edge wall form an annular actuator chamber, the diameter of each actuator chamber is greater than the diameter of driving ring, and abutment wall has a central support posts to be respectively the driven wheel element to pass in each.Mesh driving wheel and rotation as lighting a fire then respectively by driving cap, light lighter thereby driving wheel produces spark with regard to the flint that drives the spark wheel friction spring and support.But because the existence of actuator chamber makes to be difficult to hold the optimum engagement of gear that drives cap and driving wheel, so has certain difficulty on the ignition operation.

2, another kind provides the disposable lighter with anti-child's opening device, as US 6,494, and 709 B1.The safety device that anti-child opens is installed in the lighter top, and its two ends are connected on the support outer wall on outer head both sides.The safety device that anti-child opens comprises a pair of emery wheel, and each emery wheel comprises a protective disc and connecting hiding ring, and the circular edge of protective disc vertically extends so that each emery wheel is fixed on the U font support.Each protective disc all has mesopore; wheel shaft can support and install two protective discs and corresponding two driving wheels at two ends by mesopore; the diameter of inner hiding ring is bigger than the external diameter of peripheral driving wheel; so that being arranged on to hide to enclose in surface and the driving wheel in the ring, encloses between the flank of tooth safe distance; the surface engaged of the driving wheel on two emery wheels and both sides; the width of hiding ring is shorter than the thickness of driving wheel, can expose in the part of the driving wheel on knuckle-tooth surface.

Igniter comprises that base section inserts spring groove and by spring-supported flint, shaggy spark wheel is on flint, wheel shaft by its both sides is installed in the supporting walls groove, the same axle of two driving wheels and emery wheel is installed in the emery wheel both sides respectively, the surface of each driving wheel is the circular gear teeth, and the diameter of driving wheel is greater than the diameter of emery wheel.

In order to light disposable lighter, the user's that grows up thumb must have a downward power, pin emery wheel surpass behind the safe distance he (she) just thumb can touch the edge of driving wheel.This is by the rotation driving wheel, drives emery wheel and lights disposable lighter.The security performance of this corrective measure is better, but comparatively speaking, and its manufacturing, design difficulty are bigger, cause cost to strengthen, and profit reduces.

3, the method for increase components and parts strengthens the security performance of lighter, as utilize the depression on the fuselage top of existing simple type lighter bridge plate below, increase the shell fragment control piece newly and constitute one group of safety switch, below the front end of this control piece, there is a vertical follow block (to annotate: up-narrow and down-wide, the upper-thin-lower-thick of this follow block), the plate body of control piece is provided with an impenetrating mouth, the dislocation state that the projection of utilizing control piece at ordinary times to be positioned at the impenetrating mouth of the top plate body when the next and bridge plate lower end forms, make bridge plate not press down, reach the safe effect that gas can't be excessive.If but inwardly push away and on when lifting control piece, then the impenetrating mouth of control piece plate body just in time upwards entangles on the projection of bridge plate below, makes control piece can not bring into play the effect that stops, this moment, bridge plate was fallen together with control piece, gas is released for igniting.And when rising on the bridge plate released position, utilize then that the control piece follow block is up-narrow and down-wide, the mutual squeezing action of the features of shape of upper-thin-lower-thick and shell fragment, make control piece maintain lower position, the projection of the bridge plate lower end after rise this moment is misplaced with the impenetrating mouth of control piece top plate body once more, recovers the safe condition that bridge plate can't press down.Certain security performance that strengthens lighter of this kind corrective measure, but the increase of its design, manufacturing cost also is conspicuous.

No matter adopt above-mentioned which kind of scheme, all exist because of design, assembling, raw-material increase cause cost and improve, the obvious decline of the rising of selling price or profit, thereby be difficult to the drawback promoted in practice.
