Burner device

Claim 2

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 valve means; said combustion device comprising a nozzle supporting member connected to 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 biased by a coiled spring, connected to said nozzle pipe and said air control cylinder, over said air intake hole, and a nozzle head at the extreme end of said nozzle pipe; and said ignition device comprising a piezo electronic unit within a casing connected to the body, 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

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 acted upon by a threadably mounted flow control member and a needle valve in said passage downstream of said control member; 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 biased by a coiled spring, connected to said nozzle pipe and said air control cylinder, over said air intake hole, a nozzle tip mounted in a forward end of said nozzle pipe, and a nozzle head fitted into said nozzle tip to form a passage extending through said nozzle tip and nozzle head 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 4

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 acted upon by a threadably mounted flow control member and a needle valve in said passage downstream of said control member; 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 biased by a coiled spring, connected to said nozzle pipe and said air control cylinder, over said air intake hole, a nozzle tip mounted in a forward end of said nozzle pipe, and a nozzle head fitted into said nozzle tip to form a passage extending through said nozzle tip and nozzle head 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 5

The burner device according to claim 2, 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 6

The burner device according to claim 3, wherein said 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 to said connecting member on a casing of the ignition device on the body.

Claim 7

The burner device according to claim 2, wherein said movable member of said piezo electronic unit has a pusher positioned externally of the casing.

Claim 8

The burner device according to claim 2, 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 9

The burner device according to claim 6, wherein an electrode base is provided within said tip cover, and said discharge electrode is provided on said electrode base.
