Abstract

A selectively actuatable lighter device is disclosed which includes a body defining reservoir for containing a combustible gaseous medium such as butane, and having a valve arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium. Such lighter can selectively produce sparks at a location proximate to the gaseous medium exit to ignite the gaseous medium. Such lighter device embodies a resiliently releasable valve actuator which normally prevents actuation of the valve. The valve actuator includes an interfering portion which is selectively movable to a position out of interference with an interfering portion of the lighter body, so that the gaseous medium may be released and ignited by the sparks. Once the valve actuator is depressed and released, it returns to its closed or latched position to prevent actuation of the valve to the open position. To 're-use' the lighter, the valve actuator must again be moved to an unlatched position so that the valve (22) can be actuated for subsequent ignition of the gaseous medium.

At first referring to accompanying drawing 1, it has shown a kind of lighter that is in inoperative or inactive state, and lighter of the present invention comprises 12, one valve actuators that can press 14 of a main part and the flint wheel 18 with toothed surfaces 19.This off working state preferably also is a kind of blocked state, and in this state, valve actuator 14 is in blocked position, thereby can not be pressed.When valve actuator was in its latched position, one of shell 12 stoped the interception of part (not shown) can prevent from valve actuator is pressed.Press valve actuator 14 fuel will be flowed out from a fuel nozzle, and the spark ignition that is produced by the toothed surfaces 19 of flint wheel assembly 18 and firestone friction.Unless the position of valve actuator 14 is nonlocking position by locked or idle position transition, otherwise by valve actuator 14 fuel is flowed out in any case, thereby also just can not make lighter work.Position shown in attached Fig. 1 and 2 generally preferably is called as " off-position ".
The structure of valve actuator and shell, shape and their mutual alignment can be diversified, and wherein valve actuator can move between its prevention on the shell or locked position and non-locked position.In Cui embodiment of the present invention, when valve actuator is positioned at blocked position, just can prevent from it is pressed; When valve actuator moves to non-locked position, then it can be pressed.Valve actuator is the slip inwardly of valve operator by its blocked position towards the motion of non-locked position in general.For the ease of understanding, the above-mentioned motion inwardly of valve actuator comprise valve operator any part any inwardly motion or the component of this motion.After user's mobile valve actuator, valve actuator is remained on the blocked position, and the user press with the relief valve automation after make it to return automatically to blocked position.
The user normally is held in the hand the main part of lighter, rotates flint wheel with the generation spark with its thumb towards the direction on the pressed surface of valve actuator, and pins valve actuator simultaneously, and fuel is flowed out from fuel or valve nozzle.By spark that flint wheel produced with ignited fuel.This is present most lighter, comprises the common structure that disposable lighter adopts.
Referring to accompanying drawing 2, it is the cross-sectional view of the lighter that is in locked state as shown in Figure 1.More particularly valve actuator 14 is installed in (as shown in Figure 1) between the two side 13, and this sidewall is made of the bossing on the sidewall of lighter main body 12.Valve actuator 14 is installed on the sidewall 13 in rotating mode.On each sidewall 13, formed microscler hole 13A (seeing accompanying drawing 1), be used for the extension of hopper door actuator, thereby valve actuator can be rotated around the hole, in the 13A of hole, moved inwardly and outwardly.Hole 13A can have multiple different shape, elongated hole for example, it has curvature portion, under these circumstances, the slip of valve actuator in the hole will cause valve actuator the extension up and/or motion down.Hole 13A has limited the motion of valve actuator.Valve actuator 14 is connected with hollow fuel nozzle within slidably being installed in valve pocket 28.Divide 23A that hollow fuel nozzle 20 is clamped in an opening of valve actuator 14 by flange 21, counterbalance spring 11 and flange extension, for example in groove.Flange 21 and flange extension divide the 23A should be sufficiently big, and its shape can prevent that fuel nozzle 20 from skidding off from the hole of valve actuator 14.In addition, as shown in Figure 2, spring 11 is to be located by the flange 23 that is connected with fuel nozzle 20.Flange 23 is installed on the nozzle in the mode identical with flange 21.Compression spring 30 is installed in the below of valve actuator 14, and it forces fuel nozzle 20 to be pressed downward within valve pocket 28 and the lighter main body 12.Compression spring 30 makes 14 pairs of springs 11 of valve actuator apply a power, and the latter then is applied to power flange 23, and nozzle 20 is pressed in valve pocket 28 and the main part 12, prevents that fuel from flowing out from nozzle 20.In addition, the bottom of valve actuator 14 divides contacting of 23A to limit near valve actuator 14 moving downward nozzle 20 with flange extension.In such structure, valve actuator 14 is to be used for by flange 21 being applied power nozzle being risen, so that allow fuel flow out.A valve (all not showing among the figure) is housed near the retraction end of nozzle 20, is used for only pressing valve actuator 14, when rising nozzle 20, just allow fuel flow out.
In general, operation to valve actuator 14 is to make near valve actuator motion up nozzle 20, yet, in structure as shown in Figure 2, because the effect of counterbalance spring 21, the process that near valve actuator 14 is arranged in nozzle 20 that part moves upward at first, nozzle 20 remain on its downward position.More particularly, have only when being positioned near those a part of valve actuators 14 nozzle 20 one section enough distance that moves upward, when upper surface adjacent with nozzle 20 that makes valve actuator 14 and flange 21 contacted, nozzle 20 just can move upward.Comparatively ideal situation is: when lighter is in locked position, and when pressing valve actuator 14 down, owing between the prevention position 12A of the prevention position 14A of valve actuator and shell, have certain clearance, even if thereby valve actuator 14 is moved upward near nozzle 20, can not make nozzle 20 produce any motion that makes progress yet.Like this, when lighter is in blocked position,, fuel is flowed out even press valve actuator 14.This shows that in this certain clearance that leaves, so that blocked valve actuator can be pressed in the lighter of certain degree, it is useful adopting a counterbalance spring.
Lighter 10 further comprises a firestone 22, and it is contained in the hole 24 that is limited by the firestone of main body 22 and spring chamber 2g.Spring 26 is pushed down firestone 22 up, makes it to contact with the toothed surfaces 19 of flint wheel 18.Flint wheel 18 has toothed surfaces 19, be installed between the bossing 13 of sidewall in common mode and can rotate, it preferably have enough hardness also and firestone contact.Toothed surfaces 19 has suitable profile of tooth, allows to produce spark so that rub mutually with firestone 22 in toothed surfaces 19 when flint wheel 18 rotates.In addition, flint wheel 18 comprises suitable indentation 17, is convenient to allow the user rotate flint wheel 18 with finger.
Main body 12 comprises an inner chamber 15, wherein is filled with the fuel 9 such as butane, and it can gasify in common mode, produces gas medium, is flowed out by nozzle 20 under the control of a valve.Main body 12 is made by any one or more suitable materials, preferably is made of plastics.Have a radome on main body 12, it is preferably made by metal material, and its effect is to form a hurricane globe around flame, so that help fire fuel.
Except valve actuator and spring, flint wheel, firestone and spring and valve, main body 12 will comprise any part, parts, structure or the minor structure that reaches lighter in general.Therefore, said shell stops position 12A will be regarded as comprising any such parts and part or the like below.
Referring to accompanying drawing 2, valve actuator 14 is positioned at its blocked position, wherein the position of the prevention part 12A of shell 12 and can prevent that valve actuator 14 is pressed.More particularly, when attempting to press valve actuator 14, the prevention part 12A of the prevention part 14A of valve actuator 14 and shell 12 contacts, and prevents the operation to valve, thereby prevents that fuel from flowing out.Valve actuator 14 can move inwardly, arrives the extreme position that they move up to the extension of valve actuator 14 in the 13A of hole, and this point 10-14 in conjunction with the accompanying drawings describes.In addition, on such position inwardly, the stopping part 14B of valve actuator preferably contacts with the formed part 12B that leans in the shell 12.On such position inwardly, the prevention part 14A of valve actuator 14 is the prevention part 12A of alignment housings no longer, thereby valve actuator 14 can be pressed, and by valve actuator nozzle 20 is lifted.A user who wishes the operation lighter at first must force the prevention part 14A disengaging of valve actuator and the state that is prevented from of the prevention part 12B of main body 12.Accomplish this point, the user must make valve actuator 14 move inwardly, makes to stop part 14A no longer to aim at prevention part 12A.In case the user moves valve actuator 14 fully inwardly, valve actuator 14 just will remain on its nonlocking position inwardly, unless press and the relief valve actuator, this point will be in the back in conjunction with the accompanying drawings 10-14 do detailed explanation.
Referring to accompanying drawing 3, it shows valve actuator 14 in greater detail.Valve actuator 14 comprise one can with finger down by surface 31, protrusion 36, a nozzle opening 38 and the valve actuator fit structure 37 such as the hole.Fit structure 37 comprises two recesses as shown in drawings, lays respectively at the both sides of valve actuator 14.Protrusion 36 is used for being meshed with elongated hole 13A on main body 12 sidewalls, can be that rotate in the axle center with protrusion 36 so that make valve operator, and valve actuator is slided in the 13A of hole.Nozzle opening 38 is used to accept fuel nozzle 20 parts, and it is clamped between flange 21 and 23.
Valve actuator 14 is to make with the material with enough shape stabilities and rigidity, so that make it can be on the relative position between the prevention part 12A of the prevention part 14A of valve actuator 14 and shell in the whole use of lighter.The valve actuator 14 the most handy polyether compounds that contain zinc or glass are made.Other materials that can be used for making valve actuator 14 are that aluminium and other contain the polymer of glass, for example polyether sulfone or its analog, and the combination of these materials.

Fit structure 37 and 39 can have multiple different shape, position and structure.Their concrete structure is unessential for the present invention.In addition, each in the fit structure 37 and 39 can comprise the independent structure of any reasonable number.Interaction between the fit structure 37 and 39 helps lighter is remained on its locking and the nonlocking position.
Accompanying drawing 4 is side views of valve actuator as shown in Figure 3, and it has shown two the recess 37A and the 37B of the fit structure 37 of valve actuator, and the prevention part 14A of valve actuator 14.In addition, accompanying drawing 4 has shown the fit structure 40 of valve actuator, and it comprises two part 40A and 40B as shown in drawings.
Referring to accompanying drawing 5, it has shown the bottom view of valve actuator 14 as shown in Figure 3.The part 35 of valve actuator 14 is used to accept spring 30 as shown in Figure 2.This part can adopt various form, for example prodger or partly stretch into recess or hole among the valve actuator.Fuel nozzle as shown in the figure by nozzle flange 21 and 23 and spring 11 (seeing accompanying drawing 2) remain among the nozzle opening 38, their diameter is greater than the width of nozzle opening 38.
Accompanying drawing 6 has shown employing a kind of piezoelectric type lighter of the present invention in the mode of block diagram.This piezoelectric type lighter comprises percussion hammer and fuel release member 64, sparking mechanism 66, selectable electronic cutoff switch 68, stops parts 70 and valve 71.This piezoelectric type lighter is worked in common mode, and different is that pressing of percussion hammer 64 is subjected to the restriction with the prevention parts 70 of mode work of the present invention.As shown in drawings, this percussion hammer device 64 comprises a such valve actuator of actuator can prevent to produce spark, more particularly, valve actuator can by electronics/or the energy supply that mechanical system is cut off the lighter structure prevent to produce spark.In addition, valve actuator both can be the outflow that only prevents fuel selectively, also can prevent the generation of spark and the outflow of fuel simultaneously.As shown in Figure 6, owing to stop parts 70 can prevent driving to percussion hammer 64 with respect to percussion hammer 64 residing positions, thereby this lighter is in blocked position.In addition, the switch 68 of washability is in the position of opening or cutting off.
Accompanying drawing 7 has shown piezoelectric type lighter as shown in Figure 6 in the mode of block diagram, and it is in unlock state.More particularly, percussion hammer 64 can be driven percussion hammer 64 with respect to the position of stop 70.In addition, switch 68 is in the position of closure or connection.If adopt washability switch 68, for fire fuel, just must this switch of closure and make percussion hammer 64 be in nonlocking position.
After lighter is used, more specifically say so after valve actuator is pressed and is released, the present invention can automatically make valve actuator return its blocked position.Interaction between the fit structure 37 of valve actuator and the fit structure 39 of shell helps such returning automatically, and is the same with the cam 12B role shown in the accompanying drawing 10-14 as accompanying drawing 2.
In the use of lighter of the present invention, shown in accompanying drawing 1,8,9, the user is mobile valve actuator 14 (as shown in Figure 8) on direction inwardly at first, make the prevention part 14A of valve actuator 14 produce enough displacements, prevention relation (as shown in Figure 2) between the prevention part 12A of disengaging and shell 12, thereby final the permission pressed valve actuator 14, makes it to move down.For the ease of valve actuator 14 being remained on the position of a non-prevention, must make valve actuator do enough displacements inwardly, this point will 11 be done detailed explanation in conjunction with the accompanying drawings.
In addition, in case valve actuator 14 has been done enough displacements inwardly, the prevention part 14B of valve actuator just will be meshed with cam 12B or partly engagement, and the extension 36 of valve actuator will arrive the extreme position by determined its motion of hole 13A, the most nice here Fig. 2.Therefore, cam 12B also can play the effect of stop, and the motion inwardly of limiter valve actuator 14 is for the user provides benefit.(also can adopt other combination and the parts motion inwardly that comes the limiter valve actuator.) such motion inwardly makes lighter be in as shown in Figure 8 nonlocking position.Press valve actuator constantly at this, and suitably rotate flint wheel 18, just can make lighter work, also will make the part motion down as shown in Figure 9 of valve actuator 14 simultaneously.More particularly, when valve actuator 14 lifts nozzle 20, thereby when starting valve, the ignited fuel that the spark that is produced will flow out from fuel nozzle.Near valve actuator 14 lifting action fuel will be flowed out from fuel chamber nozzle makes fuel flow out by nozzle in the mode of gas medium, and lighted subsequently.
In addition, the surface 31 of pinning valve actuator 14 will make valve actuator move to its blocked position down, more particularly, when forcing valve actuator to move down, just force the prevention position 14B of valve actuator 14 to move and contact with cam 12B down, the latter moves valve actuator 14 outwardly.In this Cui scheme, in general valve actuator 14 is because the effect of cam 12B by its non-locked position towards moving outwardly of locked position at first, the fit structure 37 that it makes valve actuator produces displacements with respect to the fit structure 39 of shell, be then since when move up in the surface 31 of valve actuator 14 fit structure 39 be applied to power on the fit structure 37.
Like this, the prevention part 14A by making valve actuator is with respect to stoping part 12A to do enough displacements, and the lighter shown in the Cui embodiment of the present invention just can be by its blocked state-transition to nonlocking state.This point can realize by valve actuator 14 is slided fully inwardly.
Accompanying drawing 10-14 has shown no longer to aim at by the prevention part 14A that makes valve actuator and has stoped part 12A, thereby allowed lighter be in the required operating procedure of carrying out of unlock state.More particularly, accompanying drawing 10 has shown the valve actuator 14 that is in the lock state.Accompanying drawing 1 and 10 shown valve actuators 14 are in same locked state.Under such state, contact by the prevention part 14A of valve actuator 14 and the prevention part 12A of shell 12, when just having prevented on pointing the surface 31 that is pressed in valve actuator valve actuator 14 is pressed.As shown in Figure 10, because the prevention part 14A of valve actuator 14 is meshed with the prevention position 12A of shell 12, valve actuator 14 can not be done anyly further to move downward except the very little gap between them.For the ease of showing, not necessarily draw in proportion in the gap among the figure between prevention part 14A and the 12A.In addition, such gap neither be necessary for normal running of the present invention.
In addition, valve actuator can cause certain motion down of valve actuator, the motion down on the surface of pressing 31 of the valve actuator of more specifically saying so usually towards the inside motion of its non-locked position.Therefore, when lighter was locked, it was desirable leaving a little gap between prevention part 14A and 12A.Yet, when the shape of hole 13A is different, when the moving of the surface of pressing 31 of valve actuator, just can not make it to produce motion down inwardly.
Referring to accompanying drawing 10, when valve actuator 14 was in latched position shown in it, because spring 30 acts on the power on the valve actuator 14, the fit structure 37 of valve actuator contacted with the fit structure 39 of shell.More particularly, the recess 37A on the fit structure 37 of valve actuator is meshed with bossing 39A on the shell fit structure 39.Valve actuator 14 by the locked position shown in it inwardly or motion outwardly force near those parts the fit structure 37 of valve actuator to be moved at first up, thereby spring 30 is further compressed.Therefore, under the situation that does not apply external force, lighter remains on blocked position as shown in Figure 10.In addition, when the extension 36 of valve actuator had reached its extreme position in the 13A of hole, any motion outwardly of blocked valve actuator was just prevented by this part, preferably sees Fig. 1.
Accompanying drawing 10 has also shown formed cam 12C in the shell, and it has two projectioies, lays respectively at the both sides of spring 30.As shown in Figure 10, the fit structure 40 of valve actuator is positioned at the top of cam 12C, and the fit structure 40 of cam 12C and valve actuator can have various shape, position and structure.Their concrete structure is unessential for the present invention.In addition, each cam 12C and fit structure 40 can have the unitary part or the parts of any reasonable number.Cam 12C and fit structure 40 are not necessary for operate as normal of the present invention, because their function can be finished by the stopping part 14B of cam 12B and valve actuator.
Accompanying drawing 11 shown valve actuators 14 have moved to its nonlocking position inwardly, and get ready for being pressed.Accompanying drawing 8 all is in identical nonlocking position with accompanying drawing 11 shown valve actuators.Valve actuator 14 with and blocking portion divide 14A as shown by arrows inwardly the motion, extension 36 up to valve actuator arrives their extreme positions inwardly in the 13A of hole, and/or the stopping part 14B of valve actuator contacts with cam 12B, thereby makes the prevention part 14A of valve actuator and the prevention part 12A of shell break away from the relation that stops.Because when valve actuator 14 moves to its nonlocking position fully inwardly, the fit structure 37 of valve actuator contacts with the fit structure 39 of shell, although 30 pairs of valve actuators 14 of spring have applied a power that trends towards making it to get back to latched position, but removing the power that is applied on the surface 31 that available finger presses still can not make valve operator get back to the position of its locking, but lighter is remained on as shown in Figure 11 the nonlocking position, till valve actuator is pressed.In other words, by applying suitable power on the surface 31 of pressing at the available finger of valve actuator, make valve actuator stop part 14A to move inwardly together with it, and then the fit structure 37 that makes valve actuator contacts with the fit structure 3g of shell again, the prevention part 14A disengaging of valve actuator and the prevention of shell are concerned, just get ready for operation lighter and generation flame.
More particularly, when the non-locked position that is in as shown in Figure 11, the recess 37B of valve actuator fit structure 37 is meshed with the protruding 39A of shell fit structure 39.The recess 37A of valve actuator fit structure 37 can be meshed by any way with the protruding 39B of shell fit structure 39.In addition, cam 12C be positioned at valve actuator fit structure 40B below.Although leave certain clearance as shown in the figure between cam 12C and fit structure 40B, such gap is not necessary concerning the operate as normal of lighter of the present invention.
As shown in Figure 11, on the surface that the available finger of valve actuator 14 is pressed, apply suitable finger pressure, will make lighter be in as shown in Figure 12 state, in this state, valve actuator is pressed, thereby allows fuel to flow out (not shown) by valve and nozzle.More particularly, so valve actuator 14 is pressed compression spring 30, forced fuel nozzle 20 to move to up and partly stretch out valve housing 28 and shell 12, this point will more be clear that in accompanying drawing 13.Like this fuel nozzle is lifted up and will make fuel by flowing out by valve and nozzle 20 in the chamber 15, the spark ignition that is produced by the toothed surfaces 19 of firestone 22 and flint wheel 18.As long as on valve actuator 14, keep enough pressure, will make fuel continue to flow out and burning.Shown in 1 accompanying drawing 12 and 13, near that part the prevention part 14A by valve actuator and the prevention part 12A of shell contacts, motion down that just can limiter valve actuator 14.
Shown in accompanying drawing 12 and 13, press the surface 31 of valve actuator, valve actuator 14 is moved down and towards export-oriented its blocked position.Such motion be since when valve actuator moves down the prevention part 14B of valve actuator and cam 12B by touching.Shown in accompanying drawing 12 and 13, such contact makes valve actuator 14 move outwardly that thereby fit structure 37 that a limited distance makes valve actuator breaks away from and the contacting of the fit structure 39 of shell, and the recess 37A that makes valve actuator fit structure 37 contacts with the protruding 39A of shell fit structure 39 at least in part.In addition, such motion also can make protruding 37C at least a portion ground of valve actuator fit structure 37 and contact at the protruding 39A of shell fit structure 39 and that part between the 39B.
Motion outwardly so also is because a part of 40B and cam 12C contacting when valve actuator moves down of valve actuator.Such contact valve actuator 14 one section limited distance of moving outwardly, thereby the fit structure 3g motion that makes the fit structure 37 of valve actuator with respect to shell like that as described above.Therefore, can think valve actuator by its nonlocking position (seeing accompanying drawing 11) towards the outside motion of its latched position (seeing accompanying drawing 12 and 13) at first since cam 12B and 12C cause.
Other parts of shell, for example its sidewall 13 can be used for driving other parts of valve actuator, so that make it to move outwardly when suitably pressing valve actuator.
As shown in Figure 14, when cancellation was applied to finger pressure on the valve actuator, valve actuator 14 was because spring 30 applied forces will be moved up, and flame will extinguish.Advantage is that when valve actuator 14 moves it is also towards its blocked position motion up.As in conjunction with the accompanying drawings as described in 12 and 13, press valve actuator it is moved outwardly, the recess 37B of valve actuator breaks away from and the contacting of the protruding 3gA of shell.Yet,, do not have motion fully outwardly yet and locked fully even valve actuator is pressed fully.Have only when valve actuator moves fully up and fully outwardly, it just can enter it by the fully locked position.
When valve actuator is pressed fully, the fit structure 37 of valve actuator has produced a bias force with respect to the position of the fit structure 3g of shell, it setovers valve actuator outwardly, and valve actuator is outwards moved towards its latched position.More particularly, part as the accompanying drawing 12 and the recess 37A of shell projection 39A shown in 13 and valve actuator contacts the power that produced, it valve actuator by its position that is pressed (seeing accompanying drawing 12) when its blocked position (seeing accompanying drawing 14) moves, valve actuator is setovered outwardly.In addition, 30 pairs of locking pieces 14 of the spring shown in accompanying drawing 12 and 13 have applied a bias force, trend towards making valve actuator to move outwardly.
The present invention who introduces above obviously can realize described purpose, yet the those of ordinary skill in the present technique field still can be made some improvement to the present invention.Following claim will comprise the improvement project of all employing essentiality contents of the present invention.
More particularly, the valve actuator that requires to be protected is not limited to use in disposable lighter.In addition, valve actuator of the present invention is not limited to only to move to its nonlocking position on inwardly the direction basically.Similarly, the interception of valve actuator also can realize by being positioned at other locational prevention parts.
