Abstract
A utility lighter (1) with an ignition-resistant mechanism. The ignition-resistant function is performed by a cam mechanism (60) having a hub (61). The hub has three integral projections: the cam lever (80), the fuel-release lever (70), and the return spring (90). Integral to the cam lever is the safety button (120) which when depressed disengages the cam lever (80) from the stopper tab (110) of the trigger (100). The trigger (100) also has an inclined surface (111) below the stopper tab (110) which the cam lever (80) engages after the safety button (120) is depressed and the trigger (100) is pulled. Once the trigger (100) is pulled, the cam lever (80) moves along the inclined surface (111) rotating the cam mechanism (60). When the cam mechanism (60) is rotated the fuel-release lever (70) opens the fuel-release valve (31) allowing fuel to transfer through to the lighting rod (16). When the safety button is released the return spring (90) urges the cam mechanism (60) to rotate back to the initial locked position.
Description
Invention field
The present invention relates to general igniter, particularly have the igniter of virgin lock characteristic.
Background technology
Now, igniter obtains very general use.Multipurpose igniter discussed here generally includes the spark lever of a handgrip and an elongation.The shape of multipurpose igniter and using method have been compared several advantages with the method for common generation flame.Be apparent that most because spark lever is long, the operator of multipurpose igniter can be stood in away from the safe distance that is fired object, thereby avoid potential danger greatly.In addition, use igniter to be difficult to stretch into match or flame is lighted in narrow place at those.Yet, not understand in child or other staff of how safety and proper operation, such igniter is dangerous as any other ignition installation.Therefore be necessary for the multipurpose igniter and be equipped with security feature,, particularly child's dangerous or misuse is reduced to minimum to the babe in the wood.
Many inventions are conceived to this security consideration just.In general, these inventions are all considered to introduce a kind of safety device, forbid that trigger spark produces and/or the automatic work of combustion gas release function.For example, some multipurpose igniter has blocking device, and console panel machine 33 (Fig. 6 and Fig. 7) is got clogged in producing on the needed displacement of spark.In these igniters, locking device forbids that usually slip " on/off " switch 32 moves on to " on " position, also promptly uses other method, removes obturator from the active channel of console panel machine.
Though above-mentioned this class multipurpose igniter provides security to a certain degree, but still the space that is significantly improved.Particularly in these igniters, in case locking device (being the on/off switch) is disabled, igniter still is in nonlocking state, is triggered once more up to locking device.Therefore if the operator unties this locking device for using igniter, then forgotten keyed end firearm again again, the security feature of this igniter is just ineffective, is started once more until this locking device.
Other some inventions are attempted from stoping on the combustion gas relieving mechanism rather than stoping the plate machine operation to solve relevant safety problem.Certainly, the multipurpose igniter that comprises this device does not forbid that because of there being combustion gas to discharge flame produces, and is disengaged up to locking device on latched position.But in this class igniter, do not prevent the device that spark produces.Therefore this class igniter just part reach security purpose when using, still may produce and catch fire because the child holds such igniter near fuel gas source or near carpet, paper or other combustibles place.
In order to address the above problem, the locking device at each igniting back automatically exciting has been introduced in some invention.Thereby these igniters have two kinds of duties: lock-out state and duty.Under lock-out state, can not produce spark and flame.On the contrary, in working order, igniter is no longer locked, and can produce flame.
Thereby need one and can not only realize producing the desired Security Target of flame, can also make inexperienced user and/or child be difficult to keep the device of flame.Invention described here provides such combination.The present invention needs the safety switch of a projection at the igniter shell top, needs to pin simultaneously this button before producing flame with the plate machine.
Summary of the invention
Main purpose of the present invention is for the multipurpose igniter provides a kind of safety device, child and inexperienced user is difficult in starts this igniter accidentally.This security feature is a particular importance, because the child often is used as toy to igniter, also because igniter, has the movable part that attracts the child as toy.
Another object of the present invention is not only to avoid producing flame, also will avoid producing spark.As above-mentioned, for the igniter of forbidding the combustion gas releasing device is only arranged under lock-out state, the child still may produce spark when playing this igniter.According to the residing environment of child, if the child is making igniter near paper products or any combustible material, just may initiation fire.
Further purpose of the present invention is that an improved device is provided in the multipurpose igniter, obtains maximum security under the prerequisite that does not influence ease for use.The safety switch of Tian Jiaing has increased a simple steps for this reason, concerning the people who plans to use, the operation of this multipurpose igniter is equally simple as the multipurpose igniter that does not have security feature, but the people that non-plan is used has increased the operating procedure of alarm.
Another purpose of the present invention is that minimizing is unexpected, particularly the fire hazard that is caused by the child; Make the flame can not sustained combustion, unless carry out the function of two separation simultaneously, and the not continuous operation interruptedly of plate machine.
Last purpose of the present invention is when satisfying all security purposes, and the energy most convenient is in manufacturing, and an expense relevant with the parts manufacturing minimizes.
The purpose of this invention realizes by a cam gear of integrated several members.In a preferred embodiment, cam gear comprises a cam lever, a fuel-release lever and a back-moving spring.From safety point of view, the most important thing is that this cam gear comprises a cam lever at off-position lockplate machine.Usually the child just hopes by pulling the plate machine and is making igniter.But when doing like this, the plate machine does not move fully or basically, thereby can not produce spark or flame.Because the plate machine is locked in this position, child's pressing board machine repeatedly will be same unsuccessful outcome.
The unique method of pulling the trigger this igniter is to press safety switch.When doing like this, cam lever slave plate machine path shifts out, and the plate machine can be pressed now.Press safety switch and can cause that the combustion gas bar moves, according to the pressure size on the safety switch, fuel release valve may be opened and discharge combustion gas.Like this, second security-related key property of the present invention is that pressure very little on safety knobs just can the locking of release board machine.But such pressure can not discharge and produce the required enough combustion gas of flame.The situation person of the being to use flicking safety switch that most probable takes place is pulled the plate machine then, and this will produce spark.For lighting this spark, the user also need pin safety switch continuously to unlock, and this has just discharged enough combustion gas before the motor-driven work of plate, and produces spark and flame.
Press safety switch for the moment and unlock even above-mentioned steps has been guaranteed the child, still be difficult to produce flame, because also need to pin continuously safety switch.This is simple, is effectively notion also.But this still is a notion, and a child who moves back and forth igniter only understands this notion, could successfully use igniter.In most of the cases, child or do not know the purposes of safety switch, though or know, can not pin the sufficiently long time of safety switch simultaneously to produce flame.After through unsuccessful trial several times, the child has often just put igniter aside like this.
When the user no longer needed flame, the plate machine discharged.Thereby make back-moving spring in the cam gear can guarantee that cam lever, fuel-release lever and safety switch all get back to original fixed position, this also just automatically is locked in off working state to the plate machine again.
By top narration, can understand the present invention and realize its security purpose, and operation is unlike conventional multipurpose igniter trouble.Particularly the set position of safety switch makes in the hand that operates in the veteran of igniter and seems very simple.An adult who is familiar with the operation of multipurpose igniter only needs a finger just can keep flame.Thereby the user can use igniter safely, easily.
The unique texture of cam gear that the present invention comprises provides best safe dose, and it is very difficult that the child will hold this device, if not impossible words.The child can only have simple thinking notion.Like this, the child can attempt just to use the present invention by pulling the plate machine with conventional method.But because igniter has automatic locking apparatus, thereby can not pull the plate machine.After through unsuccessful trial several times, the child will put igniter aside.This is will use plate machine and safety switch simultaneously because the child must know before flame produces.For the child, be familiar with and hold this notion all too difficulty.
Even but child can learn the correct using method of igniter, also still can not actually use igniter.Because the relative position of plate machine and the safety switch given uses the present invention to need the user can catch the handle of igniter in hand, pulls the plate machine with forefinger, pins safety switch with thumb simultaneously.That is to say not only needs the action dexterity, also enough big hand will be arranged, i.e. Cheng Ren hand.In addition, igniter successfully uses and also needs certain strength, and child's finger is inaccessible.
In addition,, enough big hand is arranged also, and action is dexterous strong, but wants to produce flame, also must be familiar with second notion: just can keep flame when having only the plate machine to be in the percussion state even the child can grasp operating process.This is an elusive intelligence notion for the child.And the child promptly allows to association, uses the restriction also can be subjected to intelligence discussed above and muscle power.And an adult user can not have any problem in use the present invention, because except will operating two special buttons that are provided with simultaneously, do not have other requirement.
Except the advantage of above-described all secure contexts, the present invention has also obviously reduced cost, is very easy to manufacturing.Cam gear is integrated single parts, and it provides on the current market function of 3 separating components in most of multipurpose igniters at least.Moreover, two basic elements of character in the igniter 1: cam gear and safety switch can be enabled whole security features and igniter in making and using whole abilities to work.Imagine in addition these two parts are grouped together, thereby only need produce an integrated member.This can make manufacture process more save and make things convenient for certainly.
By to following the description of the drawings with to the detailed introduction of preferred embodiment, can know these and other advantage of the present invention more.
