Lighter with replaceable fuel cartridge

Abstract

A lighter incorporates with a fuel supply arrangement which includes a replaceable fuel cartridge detachably received in a receiving cavity of a casing for storing a liquefied fuel, and a gas releasable valve extended from the replaceable fuel cartridge for controlling a flow of gas from the replaceable fuel cartridge. Therefore, a user is able to refill the fuel by simply replacing a used replaceable fuel cartridge with a new replaceable fuel cartridge which is fully pre-filled with fuel.

1 . A lighter, comprising: 
 a casing having a receiving cavity and an opening communicating said receiving cavity with outside;    a gas emitting nozzle appearing at a ceiling of said casing;    an ignition system supported by said casing for producing a spark toward said gas emitting nozzle; and    a fuel supply arrangement, which comprises:    a replaceable fuel cartridge detachably received in said receiving cavity through said opening for storing a liquefied fuel, wherein said replaceable fuel cartridge comprises a gas releasable valve coupling with said gas emitting nozzle for controlling a gas flow from said replaceable fuel cartridge;    a gas releasing lever, which is pivotally mounted on said replaceable fuel cartridge, having an actuating end coupled to said gas releasable valve and a driving end arranged when said driving end is depressed, said actuating end is pivotally lifted up for releasing said liquefied fuel from said replaceable fuel cartridge; and    a gas releasing arrangement comprising an actuator movably supported within said casing to engage with said driving end of said gas releasing lever in such a manner that when said actuator is moved to depress said driving end of said gas releasing lever, said gas releasable valve releases said gas to said gas emitting nozzle for being ignited.    
   
   
       2 . The lighter, as recited in  claim 1 , wherein said actuator comprises a lighter cap pivotally mounted to said casing for enclosing said ceiling of said casing and a driving lever having an upper portion coupling with said lighter cap and a lower portion slidably engaged with said driving end of said gas releasing lever such that when said lighter cap is pivotally and upwardly folded to expose said ceiling of said casing, said driving lever is driven to depress said driving end of said gas releasing lever for releasing said gas from said replaceable fuel cartridge.  
   
   
       3 . The lighter, as recited in  claim 1 , wherein said fuel supply arrangement further comprises a sheltering cap movably supported within said casing to detachably couple with said gas releasable valve when said replaceable fuel cartridge received in said receiving cavity, and a gas transferring conduit extended from said sheltering cap to said gas emitting nozzle for guiding said gas released from said replaceable fuel cartridge to said gas emitting nozzle.  
   
   
       4 . The lighter, as recited in  claim 2 , wherein said fuel supply arrangement further comprises a sheltering cap movably supported within said casing to detachably couple with said gas releasable valve when said replaceable fuel cartridge received in said receiving cavity, and a gas transferring conduit extended from said sheltering cap to said gas emitting nozzle for guiding said gas released from said replaceable fuel cartridge to said gas emitting nozzle.  
   
   
       5 . The lighter, as recited in  claim 3 , wherein said sheltering cap, having an interior chamber detachably accommodating an operating tip of said gas releasable valve therein, is allowed to upwardly pushed to allow said gas releasable valve being lifted up for releasing said gas.  
   
   
       6 . The lighter, as recited in  claim 4 , wherein said sheltering cap, having an interior chamber detachably accommodating an operating tip of said gas releasable valve therein, is allowed to upwardly pushed to allow said gas releasable valve being lifted up for releasing said gas.  
   
   
       7 . The lighter, as recited in  claim 4 , further comprising two guiding walls supported within said casing, wherein said sheltering cap is slidably mounted between said guiding walls such that said guiding walls guides a movement of said sheltering cap when said sheltering cap is upwardly pushed by said gas releasable valve.  
   
   
       8 . The lighter, as recited in  claim 6 , further comprising two guiding walls supported within said casing, wherein said sheltering cap is slidably mounted between said guiding walls such that said guiding walls guides a movement of said sheltering cap when said sheltering cap is upwardly pushed by said gas releasable valve.  
   
   
       9 . The lighter, as recited in  claim 7 , wherein each of said guiding walls has a transverse stopper ridge integrally and inwardly defined thereon, so that when said gas releasing valve is lifted up to push said sheltering cap upwardly, said stopper ridges block a further upward movement of said sheltering cap.  
   
   
       10 . The lighter, as recited in  claim 8 , wherein each of said guiding walls has a transverse stopper ridge integrally and inwardly defined thereon, so that when said gas releasing valve is lifted up to push said sheltering cap upwardly, said stopper ridges block a further upward movement of said sheltering cap.  
   
   
       11 . The lighter, as recited in  claim 4 , wherein said gas transferring conduit is a flexible gas tube allowing said gas to flow towards said gas emitting nozzle when said sheltering cap is pushed upwardly.  
   
   
       12 . The lighter, as recited in  claim 8 , wherein said gas transferring conduit is a flexible gas tube allowing said gas to flow towards said gas emitting nozzle when said sheltering cap is pushed upwardly.  
   
   
       13 . The lighter, as recited in  claim 10 , wherein said gas transferring conduit is a flexible gas tube allowing said gas to flow towards said gas emitting nozzle when said sheltering cap is pushed upwardly.  
   
   
       14 . The lighter, as recited in  claim 6 , wherein said fuel supply arrangement further comprises a sealing member mounted in said interior chamber of said sheltering cap to sealedly mount to said gas releasable valve for preventing said gas leaking when an operating tip of said gas releasable valve is slidably inserted into said interior chamber of said sheltering cap.  
   
   
       15 . The lighter, as recited in  claim 10 , wherein said fuel supply arrangement further comprises a sealing member mounted in said interior chamber of said sheltering cap to sealedly mount to said gas releasable valve for preventing said gas leaking when an operating tip of said gas releasable valve is slidably inserted into said interior chamber of said sheltering cap.  
   
   
       16 . The lighter, as recited in  claim 13 , wherein said fuel supply arrangement further comprises a sealing member mounted in said interior chamber of said sheltering cap to sealedly mount to said gas releasable valve for preventing said gas leaking when an operating tip of said gas releasable valve is slidably inserted into said interior chamber of said sheltering cap.  
   
   
       17 . The lighter, as recited in  claim 1 , further comprising means for applying an urging force against said gas releasing lever to push said actuating end thereof downwardly.  
   
   
       18 . The lighter, as recited in  claim 4 , further comprising means for applying an urging force against said gas releasing lever to push said actuating end thereof downwardly.  
   
   
       19 . The lighter, as recited in  claim 10 , further comprising means for applying an urging force against said gas releasing lever to push said actuating end thereof downwardly.  
   
   
       20 . The lighter, as recited in  claim 16 , further comprising means for applying an urging force against said gas releasing lever to push said actuating end thereof downwardly.
