Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
228 words
A burner device comprising a fuel tank and body having a size capable of being gripped by hand, and a valve device, a combustion device and an ignition device which are connected to an upper portion of said body; said valve device having a passage to which fuel is supplied from said body, said passage being provided with a control member varied by a flow control member and an opening and closing needle valve; said combustion device comprising a nozzle supporting member connected to the side of the valve device and in communication with the passage, a nozzle pipe whose rear end is connected to said nozzle supporting member and bored with an air intake hole opened and closed by an air control cylinder rotatably and retractably fitted while permitting a coiled spring to act, and a nozzle head fitted into a nozzle tip at the extreme end of said nozzle pipe to form a passage into a main passage and a sub-passage; and said ignition device comprising a piezo electronic unit within a casing connected to the body, and an operating member which is moved along with a movable member of said piezo electronic unit to move forward said air control cylinder, said ignition device being electrically connected to a discharge electrode provided at the end of the combustion device and being directed at said nozzle head.
Claim 2
Dependent Claim
228 words
A burner device comprising a fuel tank and body having a size capable of being gripped by hand, and a valve device, a combustion device and an ignition device which are connected to an upper portion of said body; said valve device having a passage to which fuel is supplied from said body, said passage being provided with a control member varied by a flow control member and an opening and closing needle valve; said combustion device comprising a nozzle supporting member connected to the side of the valve device and in communication with the passage, a nozzle pipe whose rear end is connected to said nozzle supporting member and bored with an air intake hole opened and closed by an air control cylinder rotatably and retractably fitted while permitting a coiled spring to act, and a nozzle head fitted into a nozzle tip at the extreme end of said nozzle pipe to form a passage into a main passage and a sub-passage; and said ignition device comprising a piezo electronic unit within a casing connected to the body, and an operating member which is moved along with a movable member of said piezo electronic unit to move forward said air control cylinder, said ignition device being electrically connected to a discharge electrode provided at the end of the combustion device and being directed at said nozzle head.
Claim 3
Dependent Claim
46 words
The burner device according to claim 1, wherein said body is interiorly provided with a fuel filling valve, and a fuel supply pipe whose upper end extends through an upper plate of the body and having an upwardly-directed U-shaped pipe mounted on a lower end thereof.
Claim 4
Dependent Claim
45 words
The burner device according to claim 1, wherein sid valve device is secured to the body through a connecting member at the upper end of said fuel supply pipe and positioned at a right angle on a casing of the ignition device on the body.
Claim 5
Dependent Claim
24 words
The burner device according to claim 1, wherein said movable member of said piezo electronic unit has a pusher positioned externally of the casing.
Claim 6
Dependent Claim
41 words
The burner device according to claim 1, including a tip cover, and said nozzle head having a spline groove in the periphery at the rear thereof and is fitted into said nozzle tip to form said main passage and said sub-passage.
Claim 7
Dependent Claim
27 words
The burner device according to claim 1, wherein an electrode base is provided within said tip cover, and said discharge electrode is provided on said electrode base.
