- As for windproof lighters, they are advantageous mainly in strong wind resistance, high combustion temperature and fast ignition, which all come out of its complex structure and high precision of their constituent parts, and the operation process thereof is that fuel gas from the outlet valves goes through the nozzle's mini-pore, forms a strong atomized flow in the gas mixing chamber and then is injected from diverting nozzle to make a strong windproof torch flame with high temperature. Their ignition is an impact or induction-typed electronic ignition with wires. However, it has been known that such an electronic igniter has a few defects: 1) The times of electronic ignition is extremely limited-no effective spark could be produced after 2,000-3,000 times of ignition. For a few of such lighters, their times of ignition may come up to above 5,000, but their manufacturing costs are high and once used over, they must be discarded; 2) The combustion chamber may be ignited only if the sparking point of the electronic ignition means be separated from the diverting nozzle for a certain distance and a height, or the rate of ignition success would be low or even the lighter fails to ignite. Because of such delicate requests for the separated distance and height result, the passing rate in the process of assembling the products is low, making the manufacturing cost raised; 3) The electronic igniter must have conductor wires which are covered with rubber or plastics for insulation, and the windproof combustion chamber however has a high temperature which may make the part of the conductor wires covered with rubber or plastic in the combustion chamber melted when the lighter being lighted up for a bit longer time, and further leads to deviated sparking and even failure of ignition. 4) The rubber or plastic cover of the conductor wires may be cut or pulled open during assembly process, which may result in electric leakage.
- Usually, the candlelight (flames) lighters using flint ignition are in various structures. Their gas outlet valves per se are the combustion heads, and as it is very simple in their structures and there is low requirement for igniting flames, the manufacturing cost is greatly reduced. In operation, the powder generated by friction between flint and igniting wheel produces sparks, lighting up the combustion head, and since the outlet valves have large ports and simple structures, the powder falling into the ports will not form a block therein. However, as the flame generated with such structure is weak, it is difficult to light up an article in open air, and it is particularly true when it is used to light up hard or thick tobacco. If, however, the flint ignition structure of the flame lighter is applied to the aforesaid windproof assembly to be used as a combustion head, as the dispersive sparks generated by the friction between flint and wheel are accompanied with powder, when in use, the powder will fall into diverting nozzles and narrow the nozzle's passages or block the nozzle's mini-pores, in full or in part, to disable the formation of strong windproof torch flame during each ignition.
- Therefore, there is a need to improve its igniter so as to produce stable and high quality windproof lighters.
- One of the main objectives of this invention is to provide a windproof lighter with a flint igniter composed of the flint ignition structure and candle flame outlet, wherein said flint igniter structure produces sparks lighting up fuel gas from the candle flame outlet and turns it into a flame which in turn ignites fuel gas in the combustion chamber of the windproof assembly so as to make a strong windproof torch flame with high temperature. And as the sparking end of the flint of said flint igniter structure is lower than the outlet of the combustion chamber or the support frame, the block of the diverting nozzles or quick flow nozzles by the powder generated by the flint when making sparks is effectively prevented and the life of use of the windproof lighter is prolonged.
- Another objective of this invention is to provide the windproof lighter with a flint igniter wherein a gas flow limitation structure is provided within the candle flame outlet with the single gas outlet valve structure, so as to adapt the candlelight flame and the windproof flame to the needs of the users.

- Referring to FIG. 1. The preferred embodiment of the windproof lighter with flint igniter according to the present invention includes a
housing 1 withsupport frame 11, agas container 2 withoutlet valve 23, and an inlet valve 22 (that may be included )for replenishing liquid fuel, anoutlet control lever 3 for acting onoutlet valve 23 ofgas container 2, awindproof assembly 4 connected with thegas diverting passage 231 of theoutlet valve 23 and composed of afilter 41, aquick flow nozzle 42, agas mixing chamber 43, adiverting nozzle 44 and acombustion chamber 45,igniter 5 for lighting up the gas from thecombustion chamber 45, awindproof metal wire 46 that may be installed on the top ofcombustion chamber 45.Said igniter 5 includes aflint ignition structure 51 at the side ofcombustion chamber 45 andcandle flame outlet 52 provided between thecombustion chamber 45 andflint ignition structure 51. A secondgas diverting pass 232 is provided betweenoutlet valve 23 andwindproof assembly 4 and connected with thecandle flame outlet 52 and has a gasflow limitation structure 521, e.g. a sponge with dense multi-pores 521, provided therewithin. Normally for multiple gas passages, fuel gas always chooses to flow towards the passage with a larger diameter, and since the diameters of the mini-pores of the quick flow nozzle in thewindproof assembly 4 are between 0.05 mm-0.15 mm, when diverted from theoutlet valve 23 towards thewindproof assembly 4 and thecandle flame outlet 52, most of the gas enters the latter and is turned into flame, while thewindproof assembly 4 has only insufficient gas and can not make it become windproof torch flame. To obtain a proper windproof torch and a flame to generate a windproof torch, a gasflow limitation structure 521 for flow distribution is provided in thecandle flame outlet 52, or the middle section ofcandle flame outlet 52 is narrowed to form the gas flow limitation structure 521 (refer to FIG. 7), orcandle flame outlet 52 may be configured with mini-pores with a preferred diameter between 0.05 mm-0.2 mm similar to that in the quick flow nozzle 42 (refer to FIG. 8) to limit the gas flow fromcandle flame outlet 52 and increase the gas flow towardswindproof assembly 4. Theflint ignition structure 51 includes anignition wheel 511 with coarse edge, aflint 512 for generating spark after friction with theignition wheel 511, aspring 53 for pressing the sparking end of theflint 512 toignition wheel 511's coarse face. Because of thespring 53, the sparking end of theflint 512 is pressed down to contact with the coarse surface of theignition wheel 511, and the contact point between theflint 512 and the coarse surface of theignition wheel 511 is called as the sparking end. Whenhousing 1'scover 12 is opened, theoutlet control lever 3 opensoutlet valve 23 to release the gas. Through the action of the gasflow limitation structure 521, partial gas goes through thegas diverting passage 231 and then gets into thefilter 41 of highly dense mesh to get rid of the impurity and grease in the gas and thus prevents such impurity or grease from getting into thequick flow nozzle 42 and blocking the mini-pores of thequick flow nozzle 42. Then the filtered gas gets into thequick flow nozzle 42 with the mini-pore's diameter between 0.05 mm-0.15 mm. The gas sprinkled from the nozzle mixes with the gas in the gas mixing chamber to generate powerful mixed fuel gas which flows out from thediverting nozzle 44 ofcombustion chamber 45 to form strong and stable windproof gas, while the other partial gas goes through the secondgas diverting passage 232 and goes out from the outlet port ofcandle flame outlet 52. When theignition wheel 511 is quickly rotated, the friction betweenignition wheel 511's coarse surface andflint 512 generates dispersive sparks, lighting up the gas from thecandle flame outlet 520 into a flame (thus theigniter 5 of the windproof torch flame is formed). Instantly, this flame lights up the gas from the windproof assembly to generate a strong and high-temperature windproof flame. One of the key structures of the present invention is that thesparking end 5121 of theflint 512 is lower than the outlet of thecombustion chamber 45 or theend 110 of thesupport frame 11, which prevents the powder from theflint 512 from falling into thecombustion chamber 45 of thewindproof assembly 4 and blocking thediverting nozzle 44 or thequick flow nozzle 42. The top 110 of thesupport frame 11 refers to the upper point of thesupport frame 11 corresponding to the sparking direction of the flint 512 (refer to FIG. 9). To achieve better result, the sparkingend 5121 of theflint 512 is made at least 3 mm lower than theoutlet 451 of thecombustion chamber 45 or the top 110 of thesupport frame 11. Aseparation structure 8 is provided between thegas mixing chamber 43 of thewindproof assembly 4 and thecandle flame outlet 52 to prevent the powder generated when theflint ignition structure 51 sends the sparks to theport 520 of the candle flame outlet from falling into thegas mixing chamber 43 and blocking the mini-pores of thequick flow nozzle 42. Thecandle flame outlet 52 is lower than theoutlet port 451 of thecombustion chamber 45 so that the flame from theport 520 of the candle flame outlet can easily light up the windproof torch at its side. When thecover 12 is closed, theoutlet control lever 3 is released to close thegas valve 23 to extinguish the windproof torch and the fire. - Refer to FIG. 2 and FIG. 3. There is another preferred embodiment of the present invention, wherein the sliding
block 6 for closing and opening said candle flame outlet for gas flow is provided at the side of saidcandle flame outlet 52. Partialcandle flame outlet 52 may be made of flexible tubes for easy press of the slidingblock 6. Abutton 7 is provided at the side ofhousing 1, and the slidingblock 6 andbutton 7 are integrated as a whole. Areset spring 71 is arranged between the slidingblock 6 and thehousing 1. One end of theoutlet control lever 3 is below thebutton 7. When theignition wheel 511 is quickly rotated by a human finger, the quick friction between the coarse surface of theignition wheel 511 and the sparkingend 5121 generates dispersive sparks. Meanwhile, thebutton 7 is pressed down to further force down theoutlet control lever 3. Then, theoutlet control lever 3 makes theoutlet valve 23 release the gas. The gas goes through the secondgas diverting passage 232, gets into thecandle flame outlet 52 and gets out ofoutlet 520, and then is ignited into fire by the dispersive spark. Thus theigniter 5 of the windproof torch is formed. Then, refer to FIG. 3,push button 7 toward the inside, the slidingclock 6 instantly presses thecandle flame outlet 52 to seal the gas from thecandle flame outlet 52 and makes the gas flow towards thegas diverting passage 231 instead. Then the gas is supplied to thewindproof assembly 4 to provide powerful and stable mixed gas to the divertingnozzle 44 of thecombustion chamber 45 and ignited into strong and windproof fire with high temperature by the flame at its side. When the finger is off, thereset spring 71 pulls the slidingblock 6 away from thecandle flame outlet 52 and thebutton 7 returns to its position with the action of the outlet control lever. Then, the windproof torch and fire go off. - Refer to FIG. 4. There is another preferred embodiment of the present invention, wherein the principle of gas transmission from the
candle flame outlet 520 to thewindproof assembly 4 is the same as that of FIG. 2. The transmission is all through the candle flame outlet's closing and opening. The differences of transmission between FIG. 4 and FIG. 2 are: the coveringpiece 522 is provided between the secondgas diverting passage 232 and thecandle flame outlet 52. Thecovering piece 522 and thecandle flame outlet 52 are integrated as a whole. The sealingpiece 523 is provided on the outlet port of the secondgas flow passage 232. Ahole 524 is made on the side wall of the second gas-divertingpassage 232. Below thehole 524 is a sealingring 525 the outlet control lever. Then, the windproof torch and fire go off. - Refer to FIG. 4. There is another preferred embodiment of the present invention, wherein the principle of gas transmission from the
candle flame outlet 520 to thewindproof assembly 4 is the same as that of FIG. 2. The transmission is all through the candle flame outlet's closing and opening. The differences of transmission between FIG. 4 and FIG. 2 are: the coveringpiece 522 is provided between the secondgas diverting passage 232 and thecandle flame outlet 52. Thecovering piece 522 and thecandle flame outlet 52 are integrated as a whole. The sealingpiece 523 is provided on the outlet port of the secondgas flow passage 232. Ahole 524 is made on the side wall of the second gas-divertingpassage 232. Below thehole 524 is a sealingring 525 sealing with thecovering piece 522. When theignition wheel 511 is quickly rotated, the flint's sparkingend 5121 produces a dispersive spark and meanwhile, theoutlet gas button 31 moves down to make theoutlet control lever 3 raise theoutlet valve 23 to let out the gas. Then the gas goes through thehole 524 on the side wall of the secondgas diverting passage 232 and the gap between the secondgas diverting passage 232 and thecovering piece 522 to the candleflame outlet port 520. Then the gas is ignited by theflint ignition structure 51 into a flame. Thuswindproof igniter 5 is formed. When the human finger continues to press down theoutlet gas button 31, theoutlet gas valve 23 further moves up. Then T-shape sealing piece 523 in thesecond gas passage 232 blocks the inlet of thecandlelight outlet 526 and thesealing ring 525 between the secondgas diverting passage 232 and thecovering piece 522 blocks the gas flow to force the gas in the secondgas diverting passage 232 on theoutlet gas valve 23 to flow towards thefirst gas passage 231 and get into thewindproof assembly 4 to form a strong mixed gas incombustion chamber 45. Instantly, the flame at theport 520 of the candle flame outlet lights up the windproof gas incombustion chamber 45 at its side to form a strong high-temperature windproof torch. - Refer to FIG. 5 and FIG. 6. The structure is similar to that of FIG. 2 and FIG. 3. The difference is that
button 7 and slidingblock 6 are separated. - Refer to FIG. 7. There is another embodiment of the present invention, wherein one end of the
outlet control lever 3 is connected to one end of thecover 12 of thehousing 1. When thecover 12 is opened, theoutlet control lever 3 with one end connected to thecover 12 opens theoutlet valve 23 to let out the gas. Thebutton 7 is provided at thehousing 1's side. The slidingblock 6 and thebutton 7 are integrated as a whole. Thereset spring 72 is provided at thebutton 7's side and in thehousing 1 so as to enable thebutton 7 smoothly reset after operation. - Refer to FIG. 8. There is another embodiment of the present invention wherein the
windproof assembly 4 and theoutlet gas valve 23 are fixed together. In such case, the support frame 11of thehousing 1 and thewindproof assembly 4 can be separately structured. When theignition wheel 511 is quickly rotated, the quick friction between the coarse surface of theignition wheel 511 and the sparkingend 5121 gives out dispersive flame. Meanwhile, the finger presses downoutlet control lever 3 to make theoutlet valve 23 let out the gas. And the gasflow limitation structure 520 makes the gas fromoutlet gas valve 23 properly distributed to thewindproof assembly 4 and thecandle flame outlet 52. Then the dispersive spark lights up the gas at theoutlet 520 of thecandle flame outlet 52 into a flame. Thus thewindproof igniter 5 is formed. Meanwhile, the flame instantly lights up the gas inwindproof assembly 4 into a strong high-temperature windproof torch. As the support frame11 and thewindproof assembly 4 are of separately arranged structure, the heat of windproof torch in thewindproof assembly 4 is hard to be transmitted to thesupport frame 11 of thehousing 1 so that the user will not be burnt by the windproof flame. - Refer to FIG. 9. There is another embodiment of the present invention wherein the
outlet control lever 3 is movably arranged on theoutlet gas valve 23 And a slidingblock 6 is installed on theoutlet control lever 3. When the ignitingwheel 511 is quickly rotated, the dispersive spark is generated by friction between the coarse surface of the ignitingwheel 511 and the sparkingend 5121. Meanwhile, the finger presses down theoutlet control lever 3 to make theoutlet gas valve 23 let out the gas. Most gas goes through the secondgas diverting passage 232 and thecandle flame outlet 52 and then goes out theport 520 of the candle flame outlet, and then ignited into a flame by theflint ignition structure 51. Thus thewindproof igniter 5 is formed. When the finger presses theoutlet control lever 3 towards the inside, the slidingblock 6 fixed on theoutlet control lever 3 presses partial soft material of thecandle flame outlet 52 to close thecandle flame outlet 52. Meanwhile, the gas from theoutlet gas valve 23 instantly turns togas diverting passage 231 to provide thewindproof assembly 4 with mixed gas which is lighted up byigniter 5. Then the windproof light generates strong windproof torch and the flame goes off after the gas in thecandle flame outlet 52 is transmitted. - Refer to FIG. 10. There is another embodiment of the present invention wherein the
igniter 5 includes aflint ignition structure 51 provided at the side ofcombustion 45 and acandle flame outlet 52 provided on one side of theflint ignition structure 51. Theflint ignition structure 51 includes anignition wheel 511, aflint 512 and aspring 53 or anauxiliary wheel 5112 connected to the central axle of theignition wheel 511. When a user uses the lighter, his finger can turn theauxiliary wheel 5112 to drive theignition wheel 511. - Refer to FIG. 11. There is a second embodiment of the present invention wherein the lighter includes: a
housing 1 with asupport frame 11, afuel container 2 withoutlet valve 23, agas diverting passage 231 on theoutlet valve 23, awindproof assembly 4 connected with thegas diverting passage 231 on theoutlet valve 23 and composed of afilter 41, aquick flow nozzle 42, agas mixing chamber 43, a divertingnozzle 44 and acombustion chamber 45, and anigniter 5 lighting up the gas incombustion chamber 45. Saidcombustion chamber 45 may have awindproof metal wire 46 provided on the upper part thereof, and there is asecond outlet valve 23′ configured in thegas container 2, on which a secondoutlet control lever 3′ is configured thereon. Said igniter includes a flint ignition structure provided on the side of thecombustion chamber 45 and acandle flame outlet 52 provided between saidflint ignition structure 51 and saidcombustion chamber 45. Agas diverting passage 232′ is arranged between thesecond outlet valve 23′ and thecandle flame outlet 52. Saidcandle flame outlet 52 is connected with saidsecond outlet valve 23′ through thegas diverting passage 232′, and thecandle flame outlet 52 is lower than the outlet of saidcombustion chamber 45, such that the flame generated by thecandle flame outlet 52 may easily light up the windproof torch at its side. Theflint ignition structure 51 includes anignition wheel 511 with a coarse edge, aflint 512 for generating sparks at its friction with theignition wheel 511 and a spring means 53 for pressing said sparkingend 5121 of theflint 512 to contact with saidignition wheel 511. On the side of saidcandle flame outlet 52, a slidingblock 6 for closing and opening the flexible part of thecandle flame outlet 52, and abutton 7 is provided at the side of thehousing 1. The slidingblock 6 and thebutton 7 are integrated or separated (see FIG. 5), and thereset spring 72 may be installed on saidbutton 7. When thecover 12 is opened, one end ofcover 12 lifts up theoutlet control lever 3 and the secondoutlet control lever 3′ connected to theoutlet control lever 3 making theoutlet valve 23 and thesecond outlet valve 23′ release the gas. The diameter of the mini-pores of thequick flow nozzle 42 in thewindproof assembly 4 is between 0.05-0.15 and thus constitutes some resistance to gas flow, while thecandle flame outlet 52 usually has a larger hole for the gas flows through easily. So, the most of the gas, having come out of theoutlet valve 23′ and entered thecandle flame outlet 52, forms a gas flow at theoutlet 520. When the human finger quickly rotates theignition wheel 511, the dispersive spark generated at the quick friction between the coarse surface of theignition wheel 511 and the sparkingend 5121 lights up the gas from the candleflame outlet port 520 and turns it into a flame. Thus thewindproof igniter 5 is formed. And thereafter, when thebutton 7 is pressed towards the inside, the slidingblock 6 on thebutton 7 instantly presses thecandle flame outlet 52, blocking the gas flow in thecandle flame outlet 52, making the gas turn to theoutlet valve 23 and get into thewindproof assembly 4 and providing to the divertingnozzle 44 of thecombustion chamber 45 with a strong and stable mixed inflammable gas, which may instantly be ignited by the flame at its side to form a strong and high-temperature windproof torch. At the same time, the flame goes off. One of the key structures according to the present invention is that the sparkingend 5121 of theflint 512 is lower than theoutlet 451 of thecombustion 45,, or thetop end 110 of thesupport frame 11, and thus preventsflint 512's powder which would block the divertingnozzle 44 or thequick flow nozzle 42 from falling into thecombustion chamber 45 of thewindproof assembly 4 whenflint 512 sends spark to candle flame outlet. Thetop end 110 of thesupport frame 11 refers to the high point ofsupport frame 11 corresponding to the sparking direction of the flint 512 (refer to FIG. 9). A better results could be achieved if the sparkingend 5121 of theflint 512 is made 3 mm (or more) lower than theoutlet 451 of thecombustion chamber 45 or thetop end 110 of thesupport 11′ Aseparation structure 8 is provided between thegas mixing chamber 43 of thewindproof assembly 4 and thecandle flame outlet 52 to prevent the powder generated when theflint ignition structure 51 sends a spark to the candleflame outlet port 520 from falling into thegas mixing chamber 43 and blocking the mini-pores of thequick flow nozzle 42. - Refer to FIG. 12. The
flint igniter structure 51 sends spark to light up the gas at thecandle flame outlet 520 to generate the flame and light up the windproof torch. In operation, the flame and windproof torch exist at the same time. The main reason of the above is that the gasoutlet adjustment mechanism 230 enlarges the passage of theoutlet valve 23 and the gasoutlet adjustment mechanism 230′ narrows the passage of thesecond outlet valve 23′, making equal the distribution of gas in thewindproof assembly 4 and thecandle flame outlet 52, which further makes the flame and windproof torch occur simultaneously. - Refer to FIG. 13, similar to FIG. 12. The differences are: the
outlet adjustment mechanism 3 of theoutlet valve 23 has one end connected to one end of thecover 12. When thecover 12 is opened, the outlet valve releases the gas. The secondoutlet adjustment mechanism 3′ of thesecond outlet valve 23′ is in connection with theoutlet button 31 athousing 1's side. When theoutlet button 31 is pressed down, it makes thesecond outlet controller 3′ raise thesecond outlet valve 23′ and thus let out the gas. - The above preferred embodiments are only for description of the invention and cannot be construed as any limitation to the present invention. Those who are skilled in the art may make various changes and variation thereto within the spirit and scope of the present invention. Thus all the equivalent alternative technical solutions are to be deemed within the scope of the present invention which is defined by the claims herewith.
