Describe the operation of actuation component 25 below in detail with reference to Fig. 6 and 8.With reference to Fig. 9, according to lighter 2 on the other hand, this lighter comprises bar assembly 10, the following describes the details of this assembly.Bar assembly 10 can be connected in housing 4 versatilely and/or separate formation with housing 4.This bar assembly 10 can rotate between Fig. 1 and primary importance shown in Figure 10 or closed position and the second place shown in Figure 13 or open position or the position of stretching out fully.When the closed position, this bar assembly is folded near housing 4, so that transportation and storage of lighter 2.When complete extended position, this bar assembly 10 is protruding, leaves housing 4.

With reference to Fig. 9 and 9A, this bar assembly 10 comprises the bar 101 that is fixedly connected on bottom parts 102.This bar 101 is cylindrical duct that metal is done, and this pipe can receive conduit 23 (as shown in Figure 1) and lead 28.This bar 101 also is included near the little protuberance 101a that forms one of bar free end.The little protuberance that perhaps will separate is connected in this bar.

With reference to Fig. 9 and 9A, bottom parts 102 can be contained in the recess 104 that forms on housing 4 the second ends 9.This recess 104 is between the side of housing 4.Therefore, make bar assembly 10 between these sides.

Bottom parts 102 comprises two main part 106a and 106b, is generally cylindrical shape, forms hole 108.According to shown in embodiment, main body 106a and 106b form groove 106c, make when main part 106a and 106b weld together, and form chamber 107 among this groove 106c.A kind of method that is used for welding the bottom parts sheet is a ultrasonic bonding, yet the invention is not restricted to this structure and the shape of bottom parts 102.

Main part 106b go up to form hole 109, illustrates as Figure 10 is clear, and this hole 109 is deep-slotted chip breakers, and this groove passes main part 106b and is communicated with chamber 107 (see figure 9)s that form in groove 106c and the groove.To describe the effect of deep-slotted chip breaker 109 below in detail.

With reference to figure 9, shell 4 comprises a pair of axostylus axostyle 101a and the 101b that is formed on its inner surface 112 again.Axostylus axostyle 101a is a male part, and axostylus axostyle 101b is a female part.The shape and size of these axostylus axostyles 101a and 101b are decided to be to make and the time can be in the same place by quick-snap in welding.Axostylus axostyle 101a and 101b can use ultrasonic bonding, and perhaps other known welding method of those of ordinary skill is welded.In another kind of alternative form, this axostylus axostyle 101a and 101b can separate certain distance.In case after the assembling, this axostylus axostyle 101a and 101b just extend in the hole 108, so that bar assembly 10 is connected in housing 4 rotationally.Therefore axostylus axostyle 101 constitutes the pivot P that the bar assembly rotates.The best horizontal expansion of this pivot P (promptly a side from housing 4 reaches the another side, and out of plumb is stretched out this side), and perpendicular to longitudinal axis L, yet within the scope of the invention, can comprise other orientation of pivot P.Housing 4 also comprises the liner 113 that is formed on housing 4 inner surfaces 112, so that bottom parts 102 is bearing in the recess 104.Bottom parts 102 also comprises a pair of selective erase parts in its relative both sides.For example, the O shape of a pair of rubber ring is fixed on the relative both sides of bottom parts, against liner 113.Can be with this friction means resistance of providing bar assembly 10 to rotate optionally around pivot P.

Get back to Fig. 1, lighter shell 4 also is included in the vertical wall 4f of front end 9.Bottom parts 102 also comprises the protuberance 106d that radially extends substantially.Cooperation between this wall 4f and the protuberance 106d can prevent that stopping bar 101 significantly surpasses complete extended position shown in Figure 13 along moving of direction W1.In addition, when the bar assembly is positioned at complete extended position, there is gap slightly at the protuberance 106d of vertical wall 4f and bottom parts 102.

With reference to figure 10-14, this lighter 2 has cam part 116, this cam part can releasably be located bar assembly 10 and be fixed on the diverse location in closed position (see figure 10) and the complete extended position (seeing Figure 13), and is positioned at the centre position (seeing Figure 11 and 12) between these two positions.Cam-follower 116 can also prevent user sufficient movement or slide trigger device 25 more specifically when bar assembly 10 is positioned at closed position shown in Figure 10, and lighter 2 is lighted, and can continue to prevent this big motion of trigger 25, forwarded the precalculated position to until bar assembly 10 and for example forwarded about 40 ° position to, will illustrate as following from the closed position.This stop of trigger 25 can prevent to light lighter or light flame, and method is to prevent to emit fuel.For example can prevent generation flame by preventing the generation spark.

With reference to Figure 15, cam-follower 116 is contained on the pillar 117 (clear illustrating among Fig. 9) that forms on the housing 4 rotationally.This cam-follower 116 comprises hub 118 and first and

second bonding parts

119 and 120, and stretch out from the both sides approximately relatively of hub 118 this bonding part.This hub 118 comprises the hole 118a that is used to receive pillar 117.First bonding part 119 comprises follower end 112, this end can with the cam face 124 interaction (see figure 9)s that are formed on the bottom parts 102.Second bonding part 120 comprises the second composition surface 126a that contacts with the first composition surface 62a (see figure 10) that forms on the trigger 25.Although in the drawings the first and

second composition surface

62a and 126a are expressed as

hook portions

62 and 126, the composition surface of other form that those of ordinary skill is known also is suitable for scope of the present invention.Other parts that hook 126 can alternatively engage lighter are attaching parts for example, to prevent to produce flame.

With reference to Figure 10, this cam-follower 116 makes 122 contacts of follower end and root along with cam face 124 by being shown the biasing member 128 counter-clockwise biasings of compression spring in the drawings again.On housing 4, form stand 130, and on first bonding part 119, form protuberance 132 (seeing Figure 15), so that biasing member 128 fix in position.This stand 130 and protuberance 132 are formed on the opposite parts in another embodiment.In addition, the biasing member 128 that is shown helical spring in the drawings can also be tension spring or leaf spring, perhaps the known biasing member that is fit to of other any type of those of ordinary skill.Follower end 124 can alternatively make cam-follower 116 have elasticity and be biased on the cam face 124.For example, this cam-follower 116 can be the elastomeric element of compression in housing 4, makes follower end 122 can be elastically biased toward on cam face 124.

Cam face 124 is a kind of running surfaces, comprises a series of first bonding part 134a-d, and these parts are expressed as brake component 134a-d in the drawings.The first bonding part 134a-d engages the servo-actuated end 122 of first bonding part 119.Brake component 134a-d is shown the groove that is formed on the bottom parts 102 in the drawings.This groove can receive servo-actuated end 122 to the outside bulge, make follower ends 122 radially to move inward, cam-follower 116 is clockwise rotated around pillar 117.The first brake component 134a is an angular cutouts in the illustrated embodiment, and greater than other brake component 134b-d, remaining brake component is the concave surface otch.Brake component 134a comprises inclined surface part 135, thus in follower end 122 along cam face 124 on the first brake component 134a when mobile, this inclined surface part 135 forms low pressure angle.Because this low pressure angle when biasing member 128 clockwise rotates at bottom parts 102, is compressed gradually, simultaneously the second brake component 134b is shifted to from the first brake component 134a in follower end 122, therefore, when making bar assembly 10 leave the closed position, make the user feel level and smooth little by little rotation.This low pressure angle has also reduced wearing and tearing and has acted on the pressure of cam-follower 116 and bottom parts 102.

The invention is not restricted to shape and the structure of the 134a-d of brake component shown in the figure, brake component 134a-d can be lug, spine or the protuberance that for example is formed on the bottom parts 102, these lug engagement follower ends 122, and this end is radially outward moved, cause the cam-follower inhour to rotate.The present invention also is not limited to the number and the position of brake component shown in the figure.In addition, the present invention also is not limited to the shape and the structure of cam-follower 116 and end 122 and 126.For example in order to change carriage release lever assembly 10 necessary power, can change the structure of cam-follower 116, end 122,126 and brake component 134a-d, for example, also can change the structure of cam-follower 116, end 122,126 and brake component 134-d in order to change the necessary power of extended position that the bar assembly is maintained in its closed position or comprises the centre position.

With reference to Figure 10, lighter 2 its bar assemblies 10 that illustrate are positioned at the closed position again.Servo-actuated end 122 is biased on the first brake component 134a when this position, be positioned at pivot P at a distance of the first radial distance R ₁The position.Because the first brake component 134a comprises inclined surface 135,, preferably turn over 40 ° of hook 126 ability and hook 62 disengagements afterwards so this bar assembly 10 must turn over preset distance.When bar assembly 10 was positioned at the closed position, when perhaps angle of rotation was less than preset distance, this hook 126 still faced toward with the hook 62 of trigger 25, made will engage depressing the wall 26a and the 126a that actuate 25 o'clock hooks.Hook 62,126 can separate certain distance, and perhaps doing to become can local depression of trigger 25, is enough to light lighter 2 but can not be pressed down to, and perhaps doing to become fully can not depression of trigger 25.

When

hook

62 and 126 was engaged with each other, this hook wall 62a contacted with 126a.The hook wall 62a that illustrates in the drawings, the orientation of 126a are arranged essentially parallel to vertical axis V, and this axis normal is in longitudinal axis L and pivot P.This structure of hook 62,126 can increase trigger 25 is pressed down to is enough to light the needed power of lighter.

Hook wall

62a, 126a or can tilt, for

example hook wall

62a, 126a can tilt to and be arranged essentially parallel to straight line B1, make hook 62,126 interlockings, this straight line B1 and vertical axis V deviation angle γ.This hook structures can increase trigger 25 fully is pressed down to can light the needed power of lighter.The needed power of interlocking structure can be greater than the needed power of vertical wall structures.

Hook wall

62a, 126 or can be inclined to substantially parallel lines B2, this straight line and the angled δ of vertical axis V-arrangement.When applying predetermined power, this hook will be out of shape, and throw off.This hook structures can increase trigger 25 fully is pressed down to the needed power of lighter of lighting, but the degree that increases is vertically to be or little when the angle γ than

wall

62a and 126a.

According to hook 62 that is shown in Figure 10 and 126 embodiment, abundant depression of trigger 25 and light lighter 2 when bar assembly 10 is positioned at the closed position, but, because the interaction between the hook 62,126, need be with forward extended position or the bigger power of required power during a centre position therebetween to than bar assembly.When bar assembly 10 is positioned at the closed position, fully depression of trigger 25 can change to its size of power of lighting lighter 2 needed increases, and the method for change is for example to change the angle of

hook wall

62a, 126a and/or change the used material of manufacturing hook 62,126.

Bar assembly 10 is provided at the resistance that is not intended to rotation when being positioned at the closed position, because bar assembly 10 is to extended position or along first direction W ₁Rotation slided and compression biasing spring 28 along inclined surface 135 in follower end 122.Therefore, in order to rotate this assembly 10 when bar assembly 10 is positioned at the closed position, the user must apply mutually big power by contra stem assembly, just follower end 122 is moved on inclined surface 135 and compression biasing member 128.

Those of ordinary skill in the art should know and find out, also can change needed power by the geometry of selecting to have the biasing member 128 of special elastic constant and/or change cam face 124.Utilize these features bar assembly 10 releasably can be fixed on the closed position.With reference to Fig. 1, lighter 2 also is included in the selectivity protuberance (not shown) among the housing 4 recess 4f, so that releasably bar 101 is fixed on the closed position.

With reference to Figure 10 A, 11 and 12, lighter shown in the figure 2, bar assembly 10 are positioned at the position or the centre position of stretching out the part.As shown in figure 10, this bar assembly has central shaft C when original position _W1In first centre position, shown in Figure 10 A, bar assembly 10 turns over about 20 ° corner α, and this corner α is formed on the initial central shaft C of bar 101 _W1With central axis C shown in the figure _W20Between, this moment, follower end 122 (shown in dotted line) were positioned on the first brake component 134a.

In second centre position, as shown in figure 11, bar assembly 10 turns over about 45 ° corner α, and this corner α is formed on the initial central axis C of bar 101 _W1Central shaft C with position shown in the figure _W45Between, the end of servo-actuated at this moment 122 is positioned on the second product 134b.

In the 3rd centre position, as shown in figure 12, bar assembly 10 turns over about 90 ° corner α.This corner α is formed on the central axis C of bar 101 _W1Central axis C with position shown in the figure _W90Between, follower end 122 is positioned on the 3rd brake component 134c at this moment.

In the 4th centre position, as shown in figure 14, this bar assembly 10 turns over about 135 ° corner α.This corner α is formed on the initial central axis C of bar 101 _W1Central axis C with position shown in the figure _W135Between, follower end 122 is positioned in the middle of the 3rd brake component 134c and the 4th brake component 134d at this moment.

In the position of stretching out fully, as shown in figure 13, bar assembly 10 turns over about 160 ° corner α.This corner α is formed on the initial central axis C of bar 101 _W1Central axis C with position shown in the figure _W160Between, follower end 122 is positioned on the 4th brake component 134d at this moment.

With reference to Figure 10 A, with solid line cam-follower 116 is shown among the figure and is positioned at its initial position, be shown in broken lines and be positioned at the position that it moves radially.When bar 101 leaves 20 ° of angles of its initial position, inclined surface 135 in follower end 122 (being shown in dotted line) and the brake component 134a contacts, and cam following 116 rotates around pillar 117 a little, yet hook 126 (shown in dotted line) and hook 62 still align, thereby still engage when depression of trigger 25.Therefore in this position,, trigger 25 is moved to light lighter 2 if do not apply greater than the power that (is shown in Figure 11-12 and 14) in all the other centre positions and closed position (seeing Figure 13) lights lighter.

With reference to Figure 11-13, when laying respectively on these positions among second, third and the

4th brake component

134b, 134c and the 134d in follower end 122, this follower end all is positioned at the position that separates the second radial distance R2 with pivot P.This second radial distance R2 is greater than the first radial distance R1 (see figure 10), the result, when bar assembly 10 forwards centre and complete extended position to from above-mentioned closed position, first end 8 (see figure 1)s of housing 4 are just shifted in this follower end 122, cam-follower 116 is clockwise rotated around pillar 117, and hook 126 is no longer alignd with hook 62.Therefore in these three positions,

hook wall

62a and 126a do not engage when depression of trigger 25 fully.In Figure 11, be shown in broken lines cam-follower 116 and be positioned at its original position, be positioned at the distance that it moves radially and be shown in broken lines.In Figure 12-14, cam-follower 116 is shown is positioned at its other the position that moves radially.

Bar assembly 10 demonstrates the adjustable resistance to rotating.When the bar assembly is positioned at one and a plurality of high stick force position, for example being positioned at closed position (see figure 10), extended position (seeing Figure 13) and some centre position between closed position and extended position (seeing Figure 11 and 12), a brake component among the 122 contact brake component 134a-d of follower end.On the optional position in these high bar force position, when move and respectively by second, third or the 4th brake component 134b, 134c and 134d when radially outward mobile, the rotation of bar assembly 10 will make first's 119 compression biasing members 128 along cam face 124 follower end 122.Bar moves required power less than moving needed power from position shown in Figure 11 and 13, because brake component 134a has the surface portion 135 of inclination from the closed position.As mentioned above, the user must apply sizable power by contra stem assembly 10, could compress biasing member 128, makes follower end 122 shift out brake component, thus dwang assembly 10.Therefore, lighter 2 can be optionally location or fixing and be stabilized on the whichever only position in centre position or the extended position with unclamping.For example the centre position is suitable for lighting the candle of vibration, and the position of stretching out fully is suitable for lighting barbecue rack.Those of ordinary skill should know and that as can be seen cam face can have the many brake component 134a-d that separate various distances, thereby makes that different that bar assembly 10 has any number are closed, the combination of centre and extended position and these positions.Those of ordinary skill should also be appreciated that and as can be seen, in high stick force position and the low stick force position closing and can dispose any number between the extended position fully.In addition, the closed position can be high stick force position or low stick force position, and extended position also can be high stick force position or low stick force position fully.

With reference to Figure 14, lighter shown in the figure 2, bar assembly 10 are positioned at low stick force position.Shown in low stick force position, the bar assembly is that stretch out the part, with the closed position into about 135 ° of angles.Follower end 122 and is positioned at pivot and separates the 3rd radial distance R on the A point is pressed in cam face 124 between the 3rd brake component 134c and the 4th brake component 134d ₃The position.The 3rd radial distance R ₃Be the nominal diameter of cam face 124, thus follower end 122 if follower end 122 not with brake component 134a-d in arbitrary brake component on time, just be positioned at pivot P and separate the 3rd radial distance R ₃The position, the 3rd radial distance R ₃Greater than the first radial distance R ₁With the second radial distance R ₂, the result, the 3rd radial distance is located follower end 122 like this, makes hook 126 throw off and the engaging of hook 62.Therefore when cam face 124 that follower end 122 contacts between the brake component 134a-d, just can depression of trigger 25, light lighter.As mentioned above, be positioned at the closed position or, have only the trigger of prevention 25 athleticisms to prevent to light lighter at bar assembly 10 in about 40 ° of scopes from the closed position.This angle can change in another embodiment.

Still with reference to Figure 14, the bar assembly 10 among the figure is positioned at low stick force position, and wherein the follower end contacts the cam face 124 between brake component 134c and the d, so follower end 122 does not contact with d with brake component 134c.Be arranged in the required power in high stick force position of brake component 134a-d less than the follower end in these position dwang assembly 10 required power.In low bar force position, this bar assembly 10 still provides some resistances to rotation, because biasing member 128 is positioned at its maximum compressive state, make follower end 122 be pressed on the cam face 124, follower end 122 and cam face 124 between will produce frictional force when rotating at bar assembly 10 this moment.Therefore when bar assembly 10 was positioned at low stick force position, the user need only add little power just can overcome these frictional force, makes 10 rotations of bar assembly.High stick force status requirement because the user must provide extra power that biasing member 128 is further compressed, and makes follower end 122 shift out brake component 134a-d greater than the power of low stick force position with bigger power dwang assembly 10, this power.When follower end 122 was between brake component 134a and b and brake component 134b and c, this bar assembly was positioned at low stick force position equally.

When being in high stick force position, the geometry that can change brake component 134 and follower end 122 increases or reduces dwang assembly 10 desired power, brake component can be quite dark, therefore its size and dimension follower end 122 that can closely cooperate requires to increase very big power when being positioned at high stick force position.Perhaps, these brake components can be done very shallowly with respect to follower end 122 or have excessive size, thereby required power has only a small amount of increase when being positioned at high stick force position.

With reference to Figure 10 and 13, bar 101 with first direction W ₁Opposite second direction W ₂Motion the time, can make bar 101 shift to the closed position.When shifting to the closed position, this bar 101 plays aforesaid effect, because this bar centerlock (seeing Figure 11 and 12) releasably during movement.

With reference to figure 9A, be used in an embodiment of the conduit 23 on the lighter 2 shown in Figure 1 shown in the figure.Conduit 23 comprises flexible pipe 140, and this flexible pipe constitutes the fluid supplying passage 142 that fuel delivery unit is connected in nozzle 143.Therefore this flexible pipe can be transported to nozzle 143 from fuel delivery unit with fuel F (see figure 1).The material that flexible pipe 140 is fit to is plastics.Uninsulated electric lead 144 is configured in this passage 142, and reaches second end 148 of pipe 140 from first end 146 of flexible pipe 140, and the materials that lead 144 is fit to are copper etc.In this embodiment, lead 144 is the local helix that forms at least.This helix wraps up than other parts more tightly at some parts.In another embodiment, this lead 144 can not be spiral.Fuel connector 22 is connected in the first end 142 of pipe.Nozzle 143 usefulness connectors 147 are connected in second end 148 of pipe 140.Therefore lead 144 plays conductor, and charge transport to nozzle 143, is produced spark, fire fuel.Lead 144 can also strengthen flexible pipe 140, and the anti-bent resistance of twisting is provided.

Conduit 23, connector 147 and nozzle 143 are supported on a pair of guide and the insulating element 145, only illustrate one among the figure.In case this surrounds these parts to parts 145, just insulating element 146 is enclosed within on the end of parts 145.Configuration bar 101 then.

Shown in Fig. 1-1B and 16, pipe 140 is bearing among the hole 20b of keeper 20, and is connected in fuel connector 22, makes lead 144 pass the fuel connector, and electrically contacts with electrode 15b formation.Second end 148 of pipe 140 is connected in the nozzle 143 near bar 101 heads 152.Therefore pipe 140 can be transported to from fuel delivery unit 11 fuel F the nozzle 143 at bar assembly 10 tops 152 through passage 142.This nozzle 143 can selectivity comprise that best shape is the diffuser 154 of helical spring.

With reference to figure 1 and 11, conduit 23 and lead 28 extend through at least a portion of bar assembly 10 from housing 4 inside.At that end that is connected in bottom parts 102 near metallic rod 101, electrical connecting wire 28.Lead 28 is to small part around pipe on 140.Conduit 23 stretches to nozzle 140.Rotate with respect to housing 4 in order to help the bar assembly, conduit 23 and lead 28 extend through the hole 109 on the bottom parts 102, extend through chamber 107 (see figure 9)s in the bottom parts 102.This hole 109 preferably separates certain distance with pivot P.Therefore, when bar assembly 10 rotated with respect to housing 4, this conduit 23 and lead 28 just slided to end 109b from end 109a in arc-shaped slot.The length of conduit 23 and lead 28 also makes bar 101 to rotate.

In case bar assembly 10 moves on to part position that stretch out or that stretch out fully, this lighter just can be with two kinds of different pattern operations.With reference to figure 5, each pattern is designed to stop by different way undesirable operation of casual user.First operator scheme or high motivator pattern (being high force mode) are become to use a kind of pattern or another kind of pattern with second operator scheme or low motivator pattern (promptly low force mode) by structure.The high force mode of lighter 2 is mainly according to the difference of health, specifically stops casual user by mistake to operate lighter according to the strength feature between casual user and the user that has a mind to.In this pattern, in order to operate lighter, the user need act on very high motivator or operating physical force on the trigger 25.Perhaps, the power that operation lighter 2 needed strength may add greater than casual user under this pattern, but these power are positioned at the scope of the power that the user that has a mind to can add.

The low force mode of lighter 2 is compared with high force mode, and more the recognition capability based on the user who has a mind to stops casual user to be not intended to operate lighter.Specifically be, second pattern mainly combines recognition capability and health difference, specifically is, stops the operation lighter according to stature feature between user who has a mind to and the casual user and craftsmenship.

Low force mode depends on that the user operates two parts of lighter, to change active force, changes to low motivator from high motivator, can light lighter when this masterpiece is used in lighter.Low force mode depends on that the user changes to low motivator position with the position of plunger part 63 from high motivator position.The user depresses latch 34, can promote plunger part 63.Behind the mobile plunger parts, the user just can light lighter as long as add less power on trigger.Low force mode can depend on intentionally and health difference and recognition capability difference between the casual user, method is for example to change shape, size or the position of latch with respect to trigger, perhaps alternatively or add this a kind of mode, actuate latch and needed power of trigger and distance in change.Requirement also can provide the resistance that requires level to being not intended to operation with particular order operation trigger and latch.

With reference to Fig. 5, an embodiment of the lighter 2 with high force mode and low force mode is described.Lighter shown in Fig. 3 and 5 has movable plunger part 63, and this plunger part is connected in latch 34 in operation.

In the initial or resting position of high force mode, as shown in Figure 5, plunger part 63 specifically is a part 66, is arranged in the part 56b of the otch 56 that is formed on the trigger 25.Therefore the vertical wall 56c of the wall 66a contact notch 56 of plunger part 63 is in high motivator position.When the user attempts to actuate trigger 25, vertical wall 66c will apply active force to vertical wall 66a, and this vertical wall is used in a masterpiece on the piston element 74 again, and this power is passed wall 76c and compressed spring 80.This spring 80 applies elastic force F _S, this elastic force is opposed the motion of trigger 25.At initial position spring 80 is not compress, and its length is D1.

In this embodiment, length D1 is substantially equal to the length between supporting member 4d and the piston element 76 end wall 76a.In another embodiment, length D1 can be greater than this length, thereby spring 80 is compressed when loading onto and is subjected to loading predeterminedly, and perhaps this length D1 can be less than this length.

In order under this high force mode, to actuate lighter, promptly when being positioned at slot-open-section 65b, part 66 actuates lighter, and the user needs at least with the first motivator F _T1Be added on the trigger 25, this active force is substantially equal to or greater than elastic force F _SWith all other reaction force F _OPThe (not shown) sum.This elastic force F _SComprise compression spring 80 needed power.Reaction force F _OPComprise in order to light lighter by various other elements that move and actuate and the power of assembly effect, the for example elastic force of the elastic force of back-moving spring 30 (seeing Figure 1B) in the piezoelectric unit 26, compression spring 53, the frictional force that produces by the actuation component motion and other active force that forms by various springs and biasing member, perhaps for actuating the power that lighter need overcome, these springs and biasing member constitute actuation component or actuating assembly, a fuel container part or are additional to these parts.Stop the concrete directed force F OP that lights lighter to depend on the structure and the design of lighter, therefore, will change to different lighter design from a kind of lighter design.In this pattern, if the power on the trigger of acting on is less than the first motivator F _T1, then can not light lighter.

As shown in Figure 6, will be equal to, or greater than the first motivator F at least as the user _T1Act on when actuating on 25, this trigger 25 is with displacement d, and plunger part 63 and piston element 75 compression springs 80.With reference to Figure 1B, this motion of trigger 25 makes the upper and lower part 26a and the b of piezoelectric unit 26 be under pressure together, cam part 32 will be moved on the 26a of top, valve actuator 14 is acted on the injection valve assembly 15, thereby valve rod 15a is moved forward, from compartment 2a, emit fuel F.When cam part contact valve driver element 14, between piezoelectric unit 26 and lead 144 (seeing Fig. 9 A), just form electricity and connect.Further depression of trigger 25 can make the hammer (not shown) in the piezoelectric unit hit the also piezoelectric device (not shown) in piezoelectric unit.Hit piezoelectric device or piezo-electric crystal and will produce electric pulse, these pulse edge lead 28 (see figure 1)s are sent to the little protuberance of bar 101, thereby form gap with nozzle 143.This spark also leads to valve actuator 14 from cam part 32, and then arrives valve rod 15a, and arrives electrode 15b and lead 144 through injection valve 15, arrives connector 150 and nozzle 143 then.Produce electric arc in the gap between nozzle 143 and bar 101, light the fuel of sending thus.

In high motivator pattern, when depression of trigger 25, the length D2 (see figure 6) of spring 80 is seen Fig. 5 less than length D1).In this pattern operating period, latch 34 remains essentially in the origin-location, and pillar 36a is because its position and travelling forward and do not stop trigger 25 motions in notch 60.

When unclamping trigger 25, back-moving spring 30 (seeing Figure 1B) in the piezoelectric device 26 and

spring

50 and 80 just move, and perhaps help piston element 74, plunger part 63 and trigger 25 to move to its initial resting position.Spring 16 (seeing Figure 1B) bias voltage valve actuator 14 is closed injection valve assembly 15 thus, stops fuel and carries.So just breath goes out by the flame of lighter emission.As a result, when unclamping trigger 25, this lighter is got back to its original state automatically, and promptly plunger part remains on high motivator position (see figure 5), in this position, needs high motivator to actuate trigger.

Lighter can be designed in order to light lighter in high motivator pattern, and the user must have predetermined strength.This lighter can selectivity structure like this, makes that the user can be with once motion or a finger are lighted lighter under high motivator pattern.

Perhaps, if the user who has a mind to do not wish with the first very high motivator F _T1(being high motivator) acts on this mode effect of trigger lighter, and the user who then has a mind to can operate lighter 2 with low motivator pattern (promptly low force mode), as shown in Figure 7.This operator scheme comprises repeatedly actuates motion, and in an illustrated embodiment, the user need carry out two kinds of actions for actuating, and two parts of lighter are moved.If the bar assembly (see figure 1) and the cam-follower 116 of rotation are housed in lighter, then lighter may comprise three kinds of actions in the operation of low motivator pattern, comprises the bar assembly is moved to extended position.

In the lighter of Fig. 7, low force mode comprises the position that changes plunger part 63 down, makes the motion of spring 80 non-confrontational triggers 25, and unopposed degree is identical with the degree of high force mode resistance.When low force mode, be substantially equal to or greater than the second motivator F _T2The masterpiece of (promptly low motivator) is used on the trigger 25, thereby lights lighter along with depressing latch.The second motivator F in this operator scheme _T2Preferably less than and optionally significantly less than the first motivator F _T1

As shown in Figure 7, in the low force mode of this embodiment, operation lighter 2 comprises that the free end 36 with latch 34 is pressed downwardly onto depressing position from initial position (shown in the dotted line) facing to trigger 25.Because operation between latch 34 and plunger part 63 interrelates, so the moving downward mobile pillar 36a of latch 34, this pillar makes the front end of plunger part 63 move downward again.When latch 34 and plunger part 63 were positioned at its depressing position, recess 70 (see figure 3)s received the pillar 36a of latch 34, the horizontal contact surface of the pillar when this groove 70 is formed on this position.

Latch can partly be depressed or fully depress, and obtains different results.According to the structure of lighter components, if latch is partly depressed, then wall 66a may contact vertical wall 56c, perhaps near vertical 56c.If latch 34 is pressed down to the vertical wall 56c that makes wall 66a contact or close actuation component 25, then lighter 2 still is in high force mode.If latch 34 is depressed into and makes that wall 66a is equal with wall 56c or be positioned under the wall 56c, then lighter slides into low force mode, perhaps is in low force mode.In some structure, lighter can be designed to, and when latch was depressed fully, plunger part 63 top 46 (see figure 4)s just complete and trigger 25 disengaged (for example below).

In order to actuate lighter under low force mode, the power that acts on the trigger is the second motivator F _T2At least must overcome aforesaid reaction force F _OP, just can actuate lighter.In addition, if plunger part 63 contact triggers 25, then second motivator also must overcome the frictional force that actuation component was produced by this contact between moving period.Yet this depends on that the user is that part is depressed latch or depressed latch fully, and the user not necessarily needs to overcome the extra elastic force F that is applied by spring 80 _S(see figure 5).Depress as fruit part, then the pattern of lighter depends on that vertical wall 66a is contact vertical wall 56c or contact trigger 25.Under the situation of vertical wall 66a contact vertical wall 56c, the user still must overcome because extension 66 still is arranged in the high-tension that slot-open-section 56b causes.

With reference to figure 8, under the situation of plunger part 63 contact slot-open-section 56a upper surfaces, must overcome the power that causes by contact.If depress fully, then the user does not need to overcome any elastic force, because wall 66a does not contact with wall 56c.As a result, hang down the second motivator F that force mode needs _T2The first motivator F less than high force mode requirement _T1If design lighter like this, make depressing fully of latch 34 that plunger part 63 and actuation component 25 are disengaged, then elastic force F _S(see figure 5) can be substantially zero.Therefore predetermined motivator is removed elastic force F _SAnd do not have active force outward basically, be zero.Yet the user must add the power that is enough to overcome other effect in the lighter and just can light lighter.

Under the low force mode of lighter shown in Figure 8, when trigger 25 was depressed, gap g (see figure 7) reduced.In addition, as shown in Figure 8, not compression of spring 80 has the original length D1, and piston remains on its original position, and spring 53 has been compressed, and trigger moves with respect to extension 66.Lighter is lighted under low force mode.When unclamping trigger 25 and latch 34, spring 30 in the piezoelectric device and back-moving spring 53 will make trigger 25 move to or help to move to original position.In addition, leaf spring 42 and spring 92 make latch 34 and plunger part 63 turn back to initial position.Therefore, lighter is got back to its initial position automatically, is positioned at high motivator position at initial position plunger part 63, and lighter needs high motivator just can light.

Preferably, in order to carry out low force mode, the user must have the skill and the recognition capability of predeterminated level, so that depress latch 34 and mobile trigger 25 according to correct order.Under low force mode, the user can press latch 34 and add motivator with different fingers with thumb.Lighter can design like this, makes just to add motivator after being preferably in latch 34 is depressed, and promptly carries out correct operating sequence and just can light lighter.Perhaps can adopt other operating sequence, the invention is not restricted to disclosed order, but also comprise the those of ordinary skill order that replaces as can be seen in order to actuate.For example, order can be that part is pulled out trigger, depresses latch, and then pulls out trigger fully.The lighter of low force mode also can utilize user intentionally and casual user's health difference, for example controls the interval of trigger and latch, perhaps regulates the operating physical force of latch, trigger or lighter, perhaps its shape and size.

In order to make lighter, make and actuate not too difficulty, high motivator F for the user who has a mind to _T1Preferably be not more than predetermined value, can think F for lighter shown in Figure 5 _T1Preferred value less than about 10kg, greater than about 5kg, preferably less than about 8.5kg, greater than about 6.5kg.Can think scope not use of the lighter of negative effect significantly for the user who has a mind to of this power, and the resistance that requires can be provided casual user's operation.These numerical example expressivitys, can be more either large or small at the operating physical force of high force mode than above-mentioned scope.

Those of ordinary skill in the art finds out that easily various factors can increase or reduce high motivator, and this motivator can make the user who has a mind to actuate easily.Traction that is provided by lighter design or the leverage of actuating trigger for example are provided these factors, and the coefficient of friction of lighter components and coefficient of elasticity, trigger structure, trigger are actuated the complexity, position component, size and dimension of action, the predetermined speed of actuating and the user's that has a mind to feature etc.For example position between trigger and the latch and/or relation and the user's that has a mind to hand is greatly or little.

The design of intraware, for example number of the structure of the structure of above-mentioned actuating assembly, bindiny mechanism, spring and all influence the user by the power that spring produces and light lighter to act on power on the trigger.For example, making trigger actuate the path needed power of moving along straight line can not equal to make trigger to actuate the path needed power of moving along non-rectilinear.Actuate and can require the user along a plurality of path movement triggers, so just make actuate more difficult.Have the preferred trigger that straight line is actuated the path although disclosed embodiment has illustrated, the ordinary person can find out obviously that the present invention can adopt the nonlinear path of actuating.

In the embodiment shown in fig. 7, the second motivator F of low force mode _T2Less than first motivator, preferably little about 2kg (but not necessarily).In the embodiment show in figure 7, low motivator F _T2Relatively good less than about 5kg greater than 1kg, more preferably greater than about 3kg.As mentioned above, these numerical value are exemplary, the invention is not restricted to these numerical value, because the numerical value of specific requirement is decided by many above-mentioned lighter design factors and casual user is operated the needed resistance of lighter.

One of lighter 2 is characterised in that, in high force mode, can carry out multiple actuate operation, as long as the user has added necessary motivator.Another feature of lighter is, under low force mode, can carry out multiple actuate operation, as long as the user depresses latch, and adds and lights needed necessary motivator of lighter and action.Specifically be, do not light that then the user can continue to depress latch, still under low force mode, actuate trigger once more and light flame if lighter is lighted a fire for the first time.

Lighter 202 at another embodiment shown in Figure 16 and the 16A.This lighter 202 is similar to the lighter 2 shown in Fig. 1-4.Lighter 202 comprises that having upper rib divides 246 trigger 225, this flank longitudinal extension.Trigger 225 also is included in the bonding part 226 of flank 246 both sides, matches with the bonding part 126 of cam-follower 216 parts in this bonding part.Lighter 202 also comprises the plunger part 263 (shown in Figure 16 A) that is slidingly connected to piston element 274.This plunger part 262 comprises U-shaped forward part and the cylindrical member 262a that extends back, and this cylindrical member receives the spring 280 of two high motivators.This spring 280 extend in the piston element 274.This spring 280 is pressed to plunger part 262 front end of lighter.This piston element 274 is connected in housing 204 rotationally and is upwards pressed by spring 292.

At high motivator position or initial position, shown in Figure 16 and 16A, this piston element 274 and plunger part 263 are aimed at top rib 246, if make depression of trigger 225 in this pattern, then spring 280 acts on elastic force Fs on the plunger part 263.This power must be overcome and just lighter can be lighted.

Under low motivator position or low force mode (as shown in figure 17), make latch 234 to pressing down, this latch makes the front end of piston element 274, thereby plunger part 263 (shown in Figure 16 A) is moved down, and makes plunger part 263 enter gap g (seeing Figure 16).Therefore, when depression of trigger 225, this upper rib divides 246 to move and not relative with spring 280 (shown in Figure 16 A) to the rear end 208 of lighter.When unclamping latch 234 and trigger 225, back-moving spring turns back to its initial position with the effect that is similar to the spring of spring 53 (see figure 1)s to this trigger in the piezoelectric unit owing to being subjected to.In addition, (effect of seeing Figure 160 turns back to its initial position owing to being subjected to spring 292 for piston element 274 and plunger part 263.As explanation to lighter 2 shown in Figure 1, can add other late spring, turn back to its initial position to help latch 23.Therefore in low motivator position, need actuate lighter than the low motivator in high motivator position, because when high motivator position, upper rib divides 246 to dock with plunger part 263, so have only the mainly motions of opposition triggers 225 of spring 280.And in low motivator position, above-mentioned frictional force or other mechanical resistance are ended trigger movement.In another embodiment, change lighter 202c, make its spring that can comprise any number 280, for example include only such spring.

Figure 18 illustrates the lighter 302 of another embodiment.This lighter 302 is similar to the lighter 202 shown in Figure 17-18.This lighter 202 comprises that having the longitudinal extension upper rib divides 346 trigger 325.This trigger also is included in the bonding part 362 of these flank 346 both sides, matches with the bonding part 326 on the cam-follower in this bonding part.

Shown in Figure 19 A, this lighter 302 also comprises plunger part 363 and the piston element 374 that is roughly U-shaped.This plunger part is connected in piston element 374 slidably.High motivator spring 380 is configured between the support unit 304e of plunger part 374 and housing.This piston element 374 is connected in shell 304 slidably.This plunger part is upwards pressed by spring 392.

At high motivator position or initial position, as shown in figure 18, this plunger part 363 divides 346 to align with upper rib, if make that actuation component 325 is depressed in this pattern, then plunger part 363 and piston element 374 move backward, and with biasing spring 380 compressions, this biasing spring is with elastic force F _SAct on piston element 374, plunger part 363 and the trigger 325.This power must be overcome and just lighter can be lighted.

Under low motivator position or low force mode, shown in power 19, to pressing down latch 334, this latch make plunger part 363 in the front portion of piston element 374 to moving down, make that when depression of trigger 325 upper rib is divided 346 rear ends 308 that can shift to lighter on plunger part 363.As a result, plunger part is mobile piston parts 374 not, thereby biasing member 380 is not opposed the motion of trigger 325.

When unclamping latch 334, this latch 334 and plunger part 363 turn back to its initial position under spring 392 (seeing Figure 18) effect.As above, can also add that other late spring turns back to its initial position to help latch 334 in the face of the explanation of lighter 2 shown in Figure 1.Therefore, when low motivator position, can actuate lighter, because spring 380 just significantly stops the motion of trigger 325 when upper rib is divided 346 butt joint plunger parts 363 with the motivator that is lower than high motivator position.In low motivator position, above-mentioned frictional force and other power may stop the motion of trigger.

Figure 20 illustrates another embodiment lighter 402.This lighter is similar to lighter shown in Figure 12.Lighter 402 comprises fixing bar and actuating assembly, and this actuating assembly comprises the trigger 425 that is slidingly connected to housing 404.This actuating assembly also comprises rotatable parts 425a and connecting rod 425b.This connecting rod 425b has the upper rib that forms gap g and divides 425c.This actuating assembly has explanation in addition at U.S. Patent application No.09/704688.In lighter 402, light the front that assembly 426 is positioned at trigger 425.

This lighter 402 also comprises double mode assembly, and this assembly comprises that structure is similar to the plunger part 463 of Fig. 3 plunger part 63 and the piston element 474 that structure is similar to Fig. 3 piston element 74.Plunger part 463 is connected in piston element 474 rotationally.High motivator spring 480 is configured between piston element 474 and the support unit 404e.This piston element 474 is connected in housing 404 slidably, and plunger part 463 is upwards pressed by spring 492.

In high motivator position or initial position (as shown in figure 20), plunger part 463 divides 425c to face toward with the upper rib of connecting rod 425b, if make and depress trigger 425 under this pattern, then rotatable parts 425a will make connecting rod 425b travel forward, contact plunger parts 463.Therefore, plunger part 463 and piston element 474 will move backward, compression biasing member 480, thereby biasing member is with elastic force F _SAct on piston element 474, plunger part 463, connecting rod 425b, rotatable parts 425a and the trigger 425.This elastic force must be overcome and just lighter can be lighted.

Under low motivator position or low force mode, as shown in figure 21, latch 434 is moved down from its initial position (shown in the dotted line), this latch will make plunger part 463 move down in the front portion of piston element 474, thereby when depression of trigger 425, the upper rib of connecting rod 425b divides 425c to travel forward, and not relative with biasing member 480, because flank 425c is mobile piston parts 474 not, and plunger part 463 receives (shown in Figure 20) by gap g.When unclamping latch 434, this latch 434 and plunger part 463 are got back to its initial position under the effect of spring 492 (being shown in Figure 20).Therefore can light lighter with the motivator that is lower than high motivator position in low motivator position, because spring 480 just stops the motion of trigger 425 when flank 425c docks plunger part 463.

Figure 22 illustrates the lighter 502 of another embodiment.This lighter 502 is similar to lighter 2 shown in Figure 1.Lighter 502 comprises actuating assembly, and this assembly comprises the trigger 25 that slidably is connected in housing 504.This actuating assembly also comprises runner assembly 525a and connecting rod 525b.This connecting rod 525b has upper rib and divides 525c and engagement end portion 525d.This actuating assembly has explanation in addition in U.S. Patent application No.09/704988.In lighter 502, light the front that assembly 526 is positioned at trigger 525.

This lighter 502 comprises that also structure that structure is similar to the bar assembly 510 of Fig. 9-14 bar assembly 10 and has abutting end part 516a and a follower end 522 is similar to the cam-follower 516 of cam-follower 116 shown in Fig. 9-15.Be similar to lighter 2 shown in Fig. 9-14, this bar assembly 510 comprises cam face 524 and brake component 534a-d.

At the various centre positions and the complete extended position of bar assembly 510, with reference to lighter 2 explanations, cam-follower 516 can rotate like this, makes end 516a not aim at the engagement end portion 525d of connecting rod 525b as top.In this position, cam-follower 516 can make connecting rod 525b and trigger 525 carry out sufficient movement, and assembly 526 is lighted in pressurization thus, lights lighter.

Figure 23 illustrates the lighter 602 of another embodiment.This lighter 602 is similar to lighter 2 shown in Figure 1.This lighter 602 comprises the trigger 625 with bonding part 662, and this bonding part comprises hole 662a.This lighter also comprises cam-follower 616, and this follower comprises the part with bonding part 616a.In closed position and various centre position, as above in the face of the explanation of lighter 2, the structure of this cam-follower and size are decided to be bonding part 616a can conjugate foramen 662a, thereby can prevent that trigger 625 from fully sliding into lights lighter 602.

As above regard to the explanation of lighter 2, at the various centre positions and the complete extended position (as shown in figure 24) of bar assembly 610, these cam-follower 616 inhours are rotated, and make end 616a break away from hole 662.In this position, cam-follower 616 can make trigger 625 fully move to and light lighter.

Figure 25 illustrates the lighter 702 of another embodiment.This lighter 702 is similar to lighter shown in Figure 12.Lighter 702 comprises actuating assembly, and this assembly comprises the trigger 725 that is slidingly connected to housing 704.This lighter 702 also comprises bar assembly 710, and this assembly can slide with respect to housing 704.And the lighter shown in Fig. 9-14 2 is similar, and bar assembly 710 comprises cam face 724 and brake component 734a-d.Lighter 702 also comprises the cam-follower 716 with engagement end portion 716a and follower end 716b.The structure of this cam-follower 716 is similar to the structure of cam-follower 116 shown in Fig. 9-15.

When bar assembly 710 was positioned at closed position shown in Figure 25, the follower end 716b of cam-follower 716 entered the first brake component 734a, and the engagement end portion 716a of cam-follower 716 aims at the engagement end portion 762 of trigger 725.Therefore, when bar assembly 710 was positioned at the closed position, this cam-follower 716 can prevent trigger 725 abundant slips and light lighter 702.When emitting, just can light fuel unit 711 actuating piezoelectric unit 72b and fuel.In lighter 702, cam-follower 716 clockwise rotates when the bar assembly stretches out.

In the various centre positions of bar assembly 710 with fully during extended position (seeing Figure 26), cam-follower 716 rotates like this, make follower end 716b be arranged in brake component 734b-d, and engagement end portion 716a no longer aims at the bonding part 726 of trigger 725, these positions at bar assembly 710, cam-follower 716 can make trigger 725 fully mobile, to lighting assembly 726 pressurizations, lights lighter 702.As mentioned above, when follower end 716a was among the brake component 734a-d, this bar assembly 716 was positioned at high bar force position.Lighter 702 is done to become: in the various centre positions of bar assembly 710, trigger 725 can not fully move to lights lighter 702.

Figure 27 illustrates the lighter 802 of another embodiment.Lighter 802 is similar to lighter 2 shown in Figure 1.Lighter 802 comprises the housing 804 with supporting member 804a, and this supporting member is used for releasably bus or conductive component 890 being fixed in the housing 804.Before conductive component 890 is connected in housing 809, the not insulation end of lead 28 (shown in Figure 1B) and conductive component 890 formation are electrically contacted.This uninsulated end can be configured between conductive component 890 and the housing 804.This conductive component 890 thereby electric wire 28 is fixed in the housing 804 on these positions.

Trigger 825 is similar to above-mentioned trigger 25, is connected in piezoelectric unit 826, and comprises the electric conductor 892 that is electrically connected on piezoelectric unit electrode 29 (shown in Figure 1A).

With reference to Figure 27 and 28, when mounted, electric conductor 892 can slide along conductive component 890, and conductive component 890 and electric conductor 892 make lead 28 be electrically connected on electrode 29 (shown in Figure 1A and 1B).

With reference to Figure 29 and 29A, the lighter 2 of another embodiment shown in the figure.This lighter 902 is substantially similar to the lighter 2 shown in Fig. 1-4, and its difference only is described below.The shape and size of lighter 902 are decided to be to be depressed latch 934 needed power and can change with the operating sequence of operated latch lock assembly 934 and trigger 925.Specifically be, if user's depression of trigger 925 before depressing latch 934 increases just then depress breech lock 934 needed power.With reference to Figure 29, lighter 902 is positioned at high force mode among the figure, and trigger 925 is positioned at initial position.In this pattern,, then need the first breech lock power F if the user depressed breech lock 934 before depression of trigger 925 _L1Depress breech lock 934, and lighter 902 is switched to low force mode from high force mode.With reference to Figure 29 A, if user's depression of trigger 925 before attempting to depress breech lock 934 then needs the second breech lock power F _L2(this power can be and more preferably greater than the first breech lock power F _L1) depress breech lock 934, and lighter 902 is switched to low force mode from high force mode.Therefore, if when lighter 902 is in high force mode, the user attempts depression of trigger 925, depresses breech lock 934 subsequently, and lighter 902 is switched to low force mode, then breech lock power F _LTo increase, and can prevent and depress breech lock 934.

Cause breech lock power F _LAn exemplary architecture example of this variation is shown in Figure 29 and 29A.As shown in the figure, first composition surface 967 is incorporated into latch 934, and second composition surface 927 is incorporated into the part (for example wall 956c) of trigger 925.Only convenient for illustration, first composition surface 967 is illustrated as the inclined surface that is formed on the plunger part 963, and second composition surface 927 is shown the inclined surface that is complementary that is formed on the trigger 925, but can adopt other structure.For example first composition surface 967 can be formed on latch 934 or the piston element 974, and second composition surface 927 can be formed on the housing 904.

When lighter 902 is positioned at high force mode, and trigger 925 is when being positioned at initial position, as shown in figure 29, first composition surface 967 and second composition surface, 927 these spline structures, if make that the user wants to depress latch 934, lighter 902 is switched to low force position, and then plunger part 963 total motions will can not make first composition surface 967 and second composition surface 927 engage basically.So in this state, depress latch 934 and lighter 902 is switched to the low needed power F of force mode _L1Power and any occurrent frictional force that only need be able to overcome spring 992 and selectivity leaf spring 942 are just much of that.In lighter shown in Figure 29, first composition surface 967 and second composition surface, 967 distance of separation X, this distance is greatly to can be with the first breech lock power F _L1Latch 934 is switched to low force position.

If the user is depression of trigger 925 before depressing breech lock 934, shown in Figure 29 A, then the distance between first composition surface 967 and second composition surface 927 will reduce (distance table that reduces is shown X ').As a result, when the user depressed latch 934, first composition surface 967 engaged second composition surface 927.This joint is except by spring 992, the optionally resistance that forms of leaf spring 942 and the accidental frictional force that may occur and the outer resistance of depressing latch 934 that also produces, result, breech lock power F _L2Greater than breech lock power F _L1Specifically be, can make plunger part 963 shift to piston element 974 by depressing the interaction (slip between the inclined surface that for example is complementary) between first composition surface 967 and second composition surface 927 that latch 934 causes, and compression spring 980.This compression of spring 980 causes the additional friction of breech lock 934 motions.Can alternatively or add this mode, the interaction of first composition surface 967 and second composition surface 927 makes trigger 925 and/or latch 934 finger motion against the user, and forms the resistance of extra prevention latch 934 motions simultaneously.

Those of ordinary skill in the art should know and find out, should this spline structure lighter 902, make make first composition surface 967 and second composition surface 927 can local depression of trigger 925 before being engaged with each other (for example when beginning to depress latch 934, distance X can be greatly can not cause first composition surface, 967 contacts, second composition surface 927 to making the part of trigger 925 depress).In this case, the user can make the predetermined distance of trigger 925 motions before depressing latch 934, depressed latch 934 this moment and lighter 902 is switched to the low required power of force mode still to remain on the first breech lock power F _L1Yet during greater than preset distance, depress latch 934 required power and will be increased to the second breech lock power F at the move distance of trigger 925 _L2

With reference to Figure 30 and 30A, shown in the figure as the lighter 1002 of lighter 902 modified examples.This lighter 1002 is substantially similar to lighter 902, if be depression of trigger 1025 before depressing latch 1034, then can prevent the user to depress latch 1034 basically.Therefore, if the user is in high force mode depression of trigger 1025 at lighter 1002, and attempt to depress latch 1034 subsequently, lighter 1002 is switched to low force mode, then first composition surface 1067 will engage second composition surface 1027, thereby can prevent or stop latch 1034 to switch to low force position basically.By for example before depressing latch 1034, during depression of trigger 1025, first composition surface 1067 and second composition surface 1027 being formed surface or raised brim overlapping or butt joint just can realize this point.Shown in Figure 30 and 30A, engage 1067 and 1027 first and second and have little gap, make that first and

second composition surfaces

1067 and 1027 just engaged when only latch 1034 moved preset distance after trigger 1029 moves preset distance.Perhaps between first and

second composition surfaces

1067 and 1027, do not form the gap basically, make that these surfaces just contact before latch 1034 moves preset distance.

In the exemplary embodiments shown in Figure 30 and the 30A, first and

second composition surfaces

1067 and 1027 are parallel to each other basically, yet first and

second composition surfaces

1067 and 1027 can be tilted in relation to each other face.In addition, though first and

second composition surfaces

1067 and 1027 are illustrated as horizontal plane (for example being arranged essentially parallel to the direction of motion Z of trigger 1025) substantially in the drawings, these composition surfaces can be the surfaces (for example tilting for direction Z) that tilts a little.In an exemplary embodiments, first composition surface 1067 and/or second composition surface 1027 can be with respect to direction Z about 5 ° of angles that tilt.Yet other angle also can tilt.Those of ordinary skill as can be seen, the structure shown in first composition surface 1067 and second composition surface 1027 are not limited to also can adopt other structure.For example first composition surface 1067 can be formed on the piston element 1074, and second composition surface 1027 can be formed on the housing 1004.In addition, first composition surface 1067 and/or second composition surface 1027 can be hook shape, other any joint shape perhaps known to the skilled.

When lighter 1002 is positioned at high force mode, and trigger 1025 is when being positioned at initial position, as shown in figure 30, first composition surface 1067 and second composition surface, 1027 distance of separation Y, if this distance Y should attempt to depress latch 1034 to the user greatly, lighter is switched low force position, and then total motion of plunger part 1063 will make first composition surface 1067 and second composition surface 1027 can not engage basically.Therefore in this state, the user can depress latch 1034, and lighter is switched to low force mode, as long as the breech lock power FL of effect can overcome the power and the accidental frictional force that occurs of spring 1092 and selectivity leaf spring 1042.

If the user is depression of trigger 1025 before depressing latch 1034, shown in Figure 30 A, then first composition surface 1067 is overlapped in second composition surface 1027.Therefore, first composition surface 1067 heads on second composition surface 1027 when the user depresses breech lock 1034, so just can stop or stop depressing of breech lock 1034 basically.In order to depress breech lock 1034 when first composition surface 1067 heads on second composition surface 1027, the user must apply sizable power, makes one or more lighter 1002 parts break or deformation.Therefore according to this embodiment, if before depressing breech lock 1034 depression of trigger 1025, can prevent basically that then the user from switching low force mode with breech lock 1034.

Those of ordinary skill in the art should know and find out, can construct lighter 1002 like this, make make first composition surface 1067 and second engage 1027 can local depression of trigger 1025 before being engaged with each other.In this case, the user can make trigger 1025 move preset distance before depressing breech lock 1034, and still can depress breech lock 1034, and lighter 1002 is switched to low force mode; Yet during greater than preset distance, this first and

second composition surface

1067 and 1027 will engage, thereby can stop or stop the motion of breech lock 1034 basically in trigger 1025 displacements.

With reference to Figure 31 and 31A, shown in the figure as the lighter 1102 of lighter 902 another modified examples.In this embodiment, before mobile breech lock 1134, make trigger 1125 move preset distance, the afunction (being that breech lock 1134 still can move to second position latching from first position latching, the still this function (for example lighter being switched to low force mode from high force mode) that can not realize breech lock 1134 that moves) of breech lock 1134 will be made.For example change the structure of breech lock 1134 and/or plunger part 1164, make when making trigger 1125 move preset distance before depressing breech lock 1134, this breech lock 1134 is thrown off with plunger part 1164 basically, so just can make the afunction of breech lock 1134.Specifically be, as shown in figure 31, when trigger 1125 is positioned at initial position (promptly not depressing position), pillar 1136a and plunger part 1164 are local at least each other facing to (for example overlapping a little), thereby depress latch 1134 and just can prevent plunger part 1164 to move on to low force position (not shown) from high force position (shown in the figure).Under state shown in Figure 31, require to depress breech lock 1134 and lighter 102 is switched to the low required breech lock power F of force mode _L1As long as it is just enough to overcome active force and any accidental frictional force that occurs of spring 1192 and selectivity leaf spring 1142.Yet shown in Figure 31 A, before depressing breech lock 1134, when making trigger 1125 move preset distance, pillar 1136 and plunger 1164 will move no longer aims at (for example without any overlapping), as a result, depressing breech lock 1134 can not make plunger part 1164 move to low force position from high force position.Under the described state of Figure 31 A, depress the required breech lock power F of breech lock 1134 _L2Only need big frictional force just enough, yet as mentioned above, the motion of breech lock 1134 can not switch to low force mode with lighter 1102 to the active force that can overcome selectivity leaf spring 1142 and any accidental appearance.Those of ordinary skill should be known and understand, shown in lighter 1102 is not limited to and illustrated structure, and can adopt the member of any number, make when before depressing breech lock 1134, making trigger 1125 move preset distance, make breech lock 1134 lose its function.

Those of ordinary skill in the art will be appreciated that, shown in lighter 902,1002,1102 is not limited to and illustrated structure, and can change breech lock power with the member of any number.Those of ordinary skill will be appreciated that, " double mode " breech lock that latch 934,1034 and 1134 is not limited to illustrate in the literary composition, and the technical staff can alternatively or add that a kind of mode controls other function of lighter.

Although various embodiment of the present invention has been described in the above, will be appreciated that the different characteristic of various embodiment can be used separately, perhaps use in combination.Therefore, the invention is not restricted to the specific embodiment described in the literary composition.In addition, should be understood that also that the design those skilled in the art can find out the various modified examples in spirit and scope of the invention.For example, can adopt the spirality helical spring of at least a concentric arrangement to replace insulated conductor 28 (being shown in Figure 1B) in conduit 23 outsides; In this case, spiral helical spring is minor insulation at least preferably, to prevent that the unwanted arc of beating takes place between spring and other lighter components.As another example, the bar assembly can alternatively be done to become and can rotate around different axis with respect to housing, perhaps does to become and can or slide with respect to the housing motion.As another example, in all embodiments, can use and have and do not have the biasing member that separates of getting back to its initial position after latch is depressed.When adopting the biasing member that separates, latch preferably can take place elastically-deformable.Know that as those of ordinary skill this modified example may require other remodeling, be electrically connected so that between piezoelectric unit and nozzle, form.

In addition, though in the embodiment that discusses now, low force mode depends on that the user operates two parts (for example trigger and breech lock), but at another embodiment, and low force mode depends on the user and operates another extra parts (for example trigger and two breech locks; Perhaps trigger, breech lock and fuel button release).

As another example, the plunger part in above-mentioned any one embodiment can form and locate like this, make the finger actuation of plunger part partly be positioned at the outside of housing, and the remainder of plunger part is positioned at housing.Therefore the plunger part finger of touching plunger part by the user is actuated part and just can be moved to low motivator position from high motivator position.In such an embodiment, lighter does not comprise latch.

In another example, lighter 2 (Fig. 1) can lack spring 53.In such an embodiment, plunger part 63 can be done to become and comprise protuberance and housing 4, and perhaps other parts can interact with this protuberance, make that when high force mode, spring 80 can be compressed and stop lighter to be lighted.When unclamping trigger after lighting under high force mode, this spring 80 makes it turn back to initial position.Yet under low force mode, can prevent that with the interaction of this protuberance high active force spring is compressed to and the identical degree of high force mode compression, make that to light the needed power of lighter lower.In this lighter, utilize the back-moving spring in the piezoelectric unit can make trigger after depressing, turn back to its initial position.

In addition, lighter comprises the double mode aspect of above-mentioned lighter, the dwang assembly aspect of lighter, the cam-follower aspect of lighter and the conduit aspect of lighter, and these aspects can be used separately or use in the mode of any combination.As a result, can use the feature of lighter 2 with independent mode or the mode that mutually combines or the mode that combines with other known feature.

Therefore, all appropriate variations examples that belong in the scope of the invention and the spirit that the technical staff finds out from invention described herein easily should be seen other embodiments of the invention as.In addition, these features of embodiment can be actuated the path with for example more complicated trigger of other RM and be combined, so that make actuating of lighter more difficult.Scope of the present invention is determined by claims.
