       [0001]     This is a divisional application of a non-provisional application, application Ser. No. 10/298,392, filed Nov. 18, 2002, in which the benefit of domestic priority date is claimed. 
     
    
     BACKGROUND OF THE PRESENT INVENTION  
       [0002]     1. Field of Invention  
         [0003]     The present invention relates to a lighter and, in particular, to a sort of lighter having a flint igniter and using inflammable gas as fuel stored in liquidness.  
         [0004]     2. Description of Related Arts  
         [0005]     Currently, lighters using inflammable gas stored in liquidness (such as butane) as fuel usually consist of the following components: a) a housing, b) a fuel container with gas outlet valve, c) a gas outlet control lever for acting on the outlet valve of the fuel container, d) an assembly connected to said outlet valve composed of a nozzle, a gas mixing chamber, a diverting nozzle and a combustion chamber, e) an electronic igniter with ignition wires.  
         [0006]     As for 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 valve gas mixing chamber and then is injected from diverting nozzle to make a strong windproof torch with high temperature. Their ignition is an impact or induction—typed electronic ignition with wires. However, it had been known that such an electronic igniter has a few defects: 1) The times an 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 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 combustion chamber however has a high temperature which may take 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.  
         [0007]     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 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&#39;s passages or block the nozzle&#39;s mini-pores, in full or in part, to disable the formation of strong windproof torch during each ignition.  
         [0008]     Therefore, there is a need to improve its igniter so as to produce stable and high quality lighters.  
       SUMMARY OF THE PRESENT INVENTION

       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0033]     Referring to  FIG. 1 . The preferred embodiment of the lighter with flint igniter according to the present invention includes: a housing  1  with support frame  11 , a gas container  2  with outlet valve  23 , and an inlet valve  22  (that may be included) for replenishing liquid fuel, an outlet control lever  3  for acting on outlet valve  23  of gas container  2 , an assembly  4  connected with the gas diverting passage  231  of the outlet valve  23  and composed of a filter  41 , a quick flow nozzle  42 , a gas mixing chamber  43 , a diverting nozzle  44  and a combustion chamber  45 , igniter  5  for lighting up the gas from the combustion chamber  45 , igniter  5  for lighting up the gas from the combustion chamber  45 , a metal wire  46  that may be installed on the top of combustion chamber  45 . Said igniter  5  includes a flint ignition structure  51  at the side of combustion chamber  45  and candle flame outlet  52  provided between the combustion chamber  45  and flint ignition structure  51 . A second gas diverting pass  232  is provided between outlet valve  23  and assembly  4  and connected with the candle flame outlet  52  and has a gas flow 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 large diameter, and since the diameters of the mini-pores of the quick flow nozzle in the assembly  4  are between 0.05-0.15 mm, when diverted from the outlet valve  23  towards the assembly  4  and the candle flame outlet  52 , most of the gas enters the latter and is turned into flame, while the assembly  4  has only insufficient gas and can not make it become windproof torch. To obtain a proper windproof torch and flame to generate a windproof torch, a gas flow limitation structure  521  for flow distribution is provided in the candle flame outlet  52 , or the middle section of candle flame outlet  52  is narrowed to form the gas flow limitation structure  521  (refer to  FIG. 7 ), or candle flame outlet  52  may be configured with mini-pores with a preferred diameter between 0.05-0.2 mm similar to that in the quick flow nozzle  42  (refer to  FIG. 8 ) to limit the gas flow from candle flame outlet  52  and increase the gas flow towards assembly  4 . The flint ignition structure  51  includes an ignition wheel  511  with coarse edge, a flint  512  for generating spark after friction with the ignition wheel  511 &#39;s coarse face. Because the sparking end of the flint  512  is pressed down to contact with the coarse with the coarse surface of the ignition wheel  511 , and the contact point between the flint  512  and the coarse surface of the ignition wheel  511  is called as the sparking end. When housing  1 &#39;s cover  12  is opened, the outlet control lever  3  opens outlet valve  23  to release the gas. Through the action of the gas flow limitation structure  521 , partial gas goes through the gas diverting passage  231  and then gets into the filter  41  of highly dense mesh to get rid of the impurity an grease in the gas and thus prevents such impurity or grease from getting into the quick flow nozzle  42  and blocking the mini-pores of the quick flow nozzle  42 . Then the filtered gas gets into the quick flow nozzle  42  with the mini-pore&#39;s diameter between 0.05-0.15 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 the diverting nozzle  44  of combustion chamber  45  to form strong and stable gas, while the other partial gas goes through the second gas diverting passage  232  and goes out from the outlet port of candle flame outlet  52 . When the ignition wheel  511  is quickly rotated, the friction between ignition wheel  511 &#39;s coarse surface and flint  512  generates dispersive sparks, lighting up the gas from the candle flame outlet  520  into a flame (thus the igniter  5  of the windproof torch is formed). Instantly, this flame lights up the gas from the assembly to generate a strong and high-temperature windproof torch. One of the key structures of the present invention is that sparking end  5121  of the flint  512  is lower than the outlet of the combustion chamber  45  of the end  110  of the support frame  11 , which prevents the powder from the flint  512  from falling into the combustion chamber  45  of the assembly  4  and blocking the diverting nozzle  44  or the quick flow nozzle  42 . The top  110  of the support frame  11  refers to the upper point of the support frame  11  refers to the upper point of the support frame  11  corresponding to the sparking direction of the flint  512  (refer to  FIG. 9 ). To achieve better result, the sparking end  5121  of the flint  512  is made at least 3 mm lower than the outlet  451  of the combustion chamber  45  or the top  110  of the support frame  11 . A separation structure  8  is provided between the gas mixing chamber  43  of the assembly  4  and the candle flame outlet  52  to prevent the powder generated when the flint ignition structure  51  sends the sparks to the port  520  of the candle flame outlet from falling into the mixing chamber  43  and blocking the mini-pores of the quick flow nozzle  42 . The candle flame outlet  52  is lower than the outlet port of  451  of the combustion chamber  45  so that the flame from the port  520  of the candle flame outlet can easily light up the windproof torch at its side. When the cover  12  is closed, the outlet control lever  3  is released to close the gas valve  23  to extinguish the windproof torch and the fire.  
         [0034]     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 said candle flame outlet  52 . Partial candle flame outlet  52  may be made of flexible tubes for easy press of the sliding block  6 . A button  7  is provided at the side of housing  1 , and the sliding block  6  and button  7  are integrated as a whole. A reset spring  71  is arranged between the sliding block  6  and the housing  1 . One end of the outlet control lever  3  is below the button  7 . When the ignition wheel  511  is quickly rotated by a human finger, the quick friction between the coarse surface of the ignition wheel  511  and the sparking end  5121  generates dispersive sparks. Meanwhile, the button  7  is pressed down to further force down the outlet control lever  3 . Then, the outlet control lever  3  makes the outlet valve  23  release gas. The gas goes through the second gas diverting passage  232 , gets into the candle flame outlet  52  and gets out of outlet  520 , and then is ignited into fire by the dispersive spark. Thus the igniter  5  of the windproof torch is formed. Then, refer to  FIG. 3 , push button  7  toward the inside, the sliding clock  6  instantly presses the candle flame outlet  52  to seal the gas from the candle flame outlet  52  and makes the gas flow towards the gas diverting passage  231  instead. Then the gas is supplied to the assembly  4  to provide powerful and stable mixed gas to the diverting nozzle  44  of the combustion chamber  45  and ignited into strong and windproof torch fire with high temperature by the flame at its side. When the finger is off, the reset spring  71  pulls the sliding block  6  away from the candle flame outlet  52  and the button  7  returns to its position with the action of the outlet control lever. Then, the windproof torch and fire go off.  
         [0035]     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 the assembly  4  is the same at that of  FIG. 2 . The transmission is all through the candle flame outlet&#39;s closing and opening. The differences of transmission between  FIG. 4  and  FIG. 2  are: the covering piece  522  is provided between the second gas diverting passage  232  and the candle flame outlet  52 . The covering piece  522  and the candle flame outlet  52  are integrated as a whole. The sealing piece  523  is provided on the outlet port of the second gas flow passage  232 . A hole  524  is made on the side wall of the second gas flow passage  232 . Below the hole  524  is a sealing ring  525  sealing with the covering piece  522 . When the ignition wheel  511  is quickly rotated, the flint&#39;s sparking end  5121  produces a dispersive spark and meanwhile, the outlet gas button  31  moves down to make the outlet control lever  3  raise the outlet valve  23  to let out the gas. The gas goes through the hole  524  on the side wall of the second gas diverting passage  232  and the gap between the second gas diverting passage  232  and the covering piece  522  to the candle flame outlet port  520 . Then the gas is ignited by the flint ignition structure  51  into a flame. Thus igniter  5  is formed. When the human finger continues to press down the outlet gas button  31 , the outlet gas valve  23  further moves up. Then T-shape sealing piece  523  in the second gas passage  232  blocks the inlet of the candlelight outlet  526  and the sealing ring  525  between the second gas diverting passage  232  and the covering piece  522  blocks the gas flow to force the gas in the second gas diverting  232  on the outlet gas valve  23  to flow towards the first gas passage  231  and get into the assembly  4  to form a strong mixed gas in combustion chamber  45 . Instantly, the flame at the port  520  of the candle flame outlet lights up the gas in combustion chamber  45  at its side to form a strong high-temperature windproof torch.  
         [0036]     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 sliding block  6  are separated.  
         [0037]     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 the cover  12  of the housing  1 . When the cover  12  is opened, the outlet control lever  3  with one end connected to the cover  12  opens the outlet valve  23  to let out the gas. The button  7  is provided at the housing  1 &#39;s side. The sliding block  6  and the button  7  are integrated as a whole. The reset spring  72  is provided at the button  7 &#39;s side and in housing  1  so as to enable the button  7  smoothly reset after operation.  
         [0038]     Refer to  FIG. 8 . There is another embodiment of the present invention wherein the assembly  4  and the outlet gas valve  23  are fixed together. In such case, the support frame  11  of the housing  1  and the assembly  4  can be separately structured. When the ignition wheel  511  is quickly rotated, the quick friction between the coarse surface of the ignition wheel  511  and the sparking end  5121  gives out dispersive flame. Meanwhile, the finger presses down outlet control lever  3  to make the outlet valve  23  let out the gas. And the gas flow limitation structure  520  makes the gas from outlet gas valve  23  properly distributed to the assembly  4  and the candle flame outlet  52 . Then the dispersive spark lights up the gas at the outlet  520  of the candle flame outlet  52  into a flame. Thus the igniter  5  is formed. Meanwhile, the flame instantly lights up the gas in assembly  4  into strong high-temperature windproof torch. As the support frame  11  and the assembly  4  are of separately arranged structure, the heat of windproof torch in the assembly  4  is hard to be transmitted to the support frame  11  of the housing  1  so that the user will not be burnt by the windproof torch.  
         [0039]     Refer to  FIG. 9 . There is another embodiment of the present invention wherein the outlet control lever  3  is movably arranged on the outlet gas valve  23  And a sliding block  6  is installed on the outlet control lever  3 . When the igniting wheel  511  is quickly rotated, the dispersive spark generated by friction between the coarse surface of the igniting wheel  511  and the sparking end  5121 . Meanwhile, the finger presses down the outlet control lever  3  to make the outlet gas valve  23  let out the gas. Most gas goes through the second gas diverting passage  232  and the candle flame outlet  52  and then goes out the port  520  of the candle flame outlet, and then ignited into a flame by the flint ignition structure  51 . Thus the igniter  5  is formed. When the finger presses the outlet control lever  3  towards the inside, the sliding block  6  fixed on the outlet control lever  3  presses partial soft material of the candle flame outlet  52  to close the candle flame outlet  52 . Meanwhile, the gas from the outlet gas valve  23  instantly turns to gas diverting passage  231  to provide the assembly  4  with mixed gas which if lighted up by igniter  5 . Then the light generates strong windproof torch and the flame goes off after the gas in the candle flame outlet  52  is transmitted.  
         [0040]     Refer to  FIG. 10 . There is another embodiment of the present invention wherein the igniter  5  includes a flint ignition structure  51  provided at the side of combustion  45  and a candle flame outlet  52  provided on one side of the flint ignition structure  51 . The flint ignition structure  51  includes an ignition wheel  511 , a flint  512  and a spring  53  or an auxiliary wheel  5112  connected to the central axle of the ignition wheel  511 . When a user uses the lighter, his finger can turn the auxiliary wheel  5112  to drive the ignition wheel  511 .  
         [0041]     Refer to  FIG. 11 . There is a second embodiment of the present invention wherein the lighter includes: a housing  1  with a support frame  11 , a fuel container  2  with outlet valve  23 , a gas diverting passage  231  on the outlet valve  23 , a assembly  4  connected with the gas diverting passage  231  on the outlet valve  23  and composed of a filter  41 , a quick flow nozzle  42 , a gas mixing chamber  43 , a diverting nozzle  44  and a combustion chamber  45 , and an igniter  5  lighting up the gas in the combustion chamber  45 . Said combustion chamber  45  may have a metal wire  46  provided on the upper part thereof, and there is second outlet valve  23 ′ configured in the gas container  2 , on which a second outlet control lever  3 ′ is configured thereon. Said igniter includes a flint ignition structure provided on the side of the combustion chamber  45  and a candle flame outlet  52  provided between said flint ignition structure  51  and said combustion chamber  45 . A gas diverting passage  232 ′ is arranged between the second outlet valve  23 ′ and the candle flame outlet  52 . Said candle flame outlet  52  is connected with said second outlet valve  23 ′ through the gas diverting passage  232 ′, and the candle flame outlet  52  is lower than the outlet of said combustion chamber  45 , such that the flame generated by the candle flame outlet  52  may easily light up the windproof torch at its side. The flint ignition structure  51  includes an ignition wheel  511  with a coarse edge, a flint  512  for generating sparks at its friction with the ignition wheel  511  and a spring means  53  for pressing and sparking end  5121  of the flint  512  to contact with said ignition wheel  511 . On the side of said candle flame outlet  52 , a sliding block  6  for closing and opening the flexible part of the candle flame outlet  52 , and a button  7  is provided at the side of the housing  1 . The sliding block  6  and the button  7  are integrated or separated (see  FIG. 5 ), and the reset spring  72  may be installed on said button  7 . When the cover  12  is opened, one end of cover  12  lifts up the outlet control lever  3  and the second outlet control lever  3 ′ connected to the outlet control lever  3  making the outlet valve  23  and the second outlet valve  23 ′ release gas. The diameter of the mini-pores of the quick flow nozzle  42  in the assembly  4  is between 0.05-0.15 and thus constitutes some resistance to gas flow, while the candle flame outlet  52  usually has a larger hole for the gas flows through easily. So, the most of the gas, having come out of the outlet  23 ′ and entered the candle flame outlet  52 , forms a gas flow at the outlet  520 . When the human finger quickly rotates ignition wheel  511 , the dispersive spark generated at the quick friction between the coarse surface of the ignition wheel  511  and the sparking end  5121  lights up the gas from the candle flame outlet port  520  and turns it into a flame. Thus the igniter  5  is formed. And thereafter, when the button  7  is pressed towards the inside, the sliding block  6  on the button  7  instantly presses the candle flame outlet  52 , blocking the gas flow in the candle flame outlet  52 , making the gas turn to the outlet valve  23  and get into the assembly  4  and providing to the diverting nozzle  44  of the combustion 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 flames go off. One of the key structures according to the present invention is that sparking end  5121  of the flint  512  is lower than the outlet  451  of the combustion  45 , or the top end  110  of the support frame  11 , and thus prevents flint  512 &#39;s powder which would block the diverting nozzle  44  or the quick flow nozzle  42  from falling into the combustion chamber  45  of the assembly  4  when flint  512  sends spark to candle flame outlet. The top end  110  of the support frame  11  refers to the high point of support frame  11  corresponding to the sparking direction of the flint  512  (refer to  FIG. 9 ). A better results could be achieved if the sparking end  5121  of the flint  512  is made 3 mm (or more) lower than the outlet  451  of the combustion chamber  45  or the top end  110  of the support  11 ′ A separation structure  8  is provided between the gas mixing chamber  43  of the assembly  4  and the candle flame outlet  52  to prevent the powder generated when the flint ignition structure  51  sends a spark to the candle flame outlet port  520  from falling into the gas mixing chamber  43  and blocking the mini-pores of the quick flow nozzle  42 .  
         [0042]     Refer to  FIG. 12 . The flint igniter structure  51  sends spark to light up the gas at the candle 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 gas outlet adjustment mechanism  230  enlarges the passage of the outlet valve  23  and the gas outlet adjustment mechanism  230 ′ narrows the passage of the second outlet valve  23 ′, making equal the distribution of gas in the assembly  4  and the candle flame outlet  52 , which further makes the flame and windproof torch occur simultaneously.  
         [0043]     Refer to  FIG. 13 , similar to  FIG. 12 . The differences are: the outlet adjustment mechanism  3  of the outlet valve  23  has one end connected to one end of the cover  12 . When the cover  12  is opened, the outlet valve releases the gas. The second outlet adjustment mechanism  3 ′ of the second outlet valve  23 ′ is in connection with the outlet button  31  at housing  1 &#39;s side. When the outlet button  31  is pressed down, it makes the second outlet controller  3 ′ raise the second outlet valve  23 ′ and thus let out gas.

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.
