Abstract
Abstract A liquefied gas-fueled smoking lighter utilizing piezoelectric elements as the voltage generation source comprising a casing, a support frame structure disposed within and secured to said casing, a high voltage generation unit comprising piezoelectric elements received in said frame structure and pinched at their opposite ends by a pressure transfer plate and a washer, an eccentric cam disposed on said pressure transfer plate for applying a pressure to said piezoelectric elements, a valve manipulation lever fixedly mounted on the shaft of said cam and having said cam shaft as the axis of rocking movement, and a valve opening and closing member disposed adjacent to said lever with at least a portion of said member positioned in the path of rocking movement of said lever.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
A liquefied gas-fueled smoking lighter utilizing piezoelectric elements as the voltage generation source comprising a support frame structure disposed within and firmly secured to the casing of said lighter, a piezoelectric element unit disposed within said frame structure pinched at its opposite ends by a pressure transfer plate and a washer, an eccentric cam having a support shaft and operatively disposed on said pressure transfer plate for applying a pressure to said piezoelectric element unit, a valve manipulation lever mounted on said shaft of the cam and having its axis of rocking movement on the cam, a burner provided in said casing above said valve manipulation lever and having primary air intake bores, said burner including a gas guiding tube coaxially disposed therein, and a valve opening and closing member disposed adjacent to said lever with at least portion of the member disposed in the rocking movement passage of said manipulation lever.
Claim 2
Dependent Claim
58 words
A liquefied gas-fueled smoking lighter utilizing piezoelectric elements as the voltage generation source as set forth in claim 2, in which a pair of discharge electrodes are electrically connected to said piezoelectric element unit and disposed in said burner above said primary air intake bores with a portion thereof extending into a gas passage defined with the burner.
Claim 3
Dependent Claim
53 words
A liquefied gas-fueled smoking lighter utilizing piezoelectric elements as the voltage generation source as set forth in claim 3, in which said burner includes a porous member in the form of wire mesh which extends across said gas passage at a point above said primary air intake bores and below said discharge electrodes.
Claim 4
Dependent Claim
76 words
A liquefied gas-fueled smoking lighter utilizing piezoelectric elements as the voltage generation sOurce as set forth in claim 3, in which said burner includes sections comprising heat-resistant material such as porcelain and water-repelling material such as resin, respectively, and said pair of discharge electrodes are received in said burner with at least a portion of the electrodes projecting into said gas passage, at least a portion of said water-repelling section being disposed between said discharge electrodes.
Claim 5
Dependent Claim
44 words
A liquefied gas-fueled smoking lighter utilizing piezoelectric elements as the voltage generation source as set forth in claim 2, in which said gas guiding tube is utilized as a main gas spouting means and said gas passage is utilized as an auxiliary gas means.
Claim 6
Dependent Claim
63 words
A liquefied gas-fueled smoking lighter utilizing piezoelectric elements as the voltage generation source as set forth in claim 3, in which said pair of discharge electrodes provide a spark discharge gap which strikes out sparks for igniting a flow of gas passing through said gas passage and an intermediate auxiliary gap is series connected to said discharge gap and said piezoelectric element unit.
Claim 7
Dependent Claim
29 words
A liquefied gas-fueled smoking lighter utilizing piezoelectric elements as set forth in claim 7, in which said intermediate auxiliary gap is provided by a pair of opposite spherical electrodes.
