JPH07103429A - Endurable nozzle capable of maintaining low flame combustion to prevent shutoff by slight vibration and breeze - Google Patents

Abstract

PURPOSE:To prevent flames from dying out, resisting vibration or breeze even if they are slight flames by cutting off the head of a pipe-shaped nozzle made of a thin walled metal so as to produce acute angle, such as an injection needle. CONSTITUTION:As the head of a pipe-shaped nozzle 1 which is made of a thin walled metal is cut off at an acute angle, an ignition port 3 is long and slender and oval in shape, which forms a tip nozzle rear wall 4 equivalent to the shape and forms a sharp tip 2 as well. As a result, when an exhaust gas is ignitied, the tip nozzle rear wall 4 engulfs flames and performs a guidance role, thereby serving as a role of a wind breakage wall. Furthermore, the ignition port 3 widens a suction area of oxygen in an open air and helps the combustion of fire while the sharp tip 2 promotes the combustion and burns red-hot immediately. Therefore, the exhaust gas makes it possible to keep the ignition for a long time with the constant red-hot tip 2 and repeat the ignition unless the tip is cooled even if the flames are temporarily shut off with temporary vibration of a breeze.

Detailed Description of the Invention

[0001]

[Industrial application] The main purpose is to heat a small pole with a weak flame rather than a high flame.

2. Description of the Related Art In a conventional gas burner nozzle, an igniting opening, which is ignited, is horizontally cut.

[0003]

When the ignition opening of the nozzle of the conventional gas burner is horizontally cut and the amount of discharged gas is large and there is a strong thermal power, it ignites without extinguishing it against some vibrations and breeze. However, in the case of a fine flame with a weak firepower, there was a problem that the fire would be extinguished even with a slight vibration or a slight wind. It is an object of the present invention to have a structure that does not extinguish a fire by enduring the slight flame or slight vibration or slight wind.

[0004]

In order to achieve the above object, the firing port is cut off at an acute angle like an injection needle.

[0005]

[Function] When the crater is cut off at an acute angle as described above, the area of the crater becomes elongated and wide, and the back wall of the crater is elongated, which serves as a guide wall for enclosing the flame and also has an effect as a windbreak wall. The bonfire prevents the breeze from the outside air, and the elongated crater has a long time to absorb a large amount of oxygen in the outside air, and the sharp tip burns quickly and burns cheaply, so the exhaust gas is constantly burning. Ignition can be made permanent by the sharpened tip, and even if it is extinguished by temporary vibration or breeze, it can be repeated as long as the tip does not cool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Explaining an embodiment with reference to the drawings, a nozzle (1) portion of a gas burner is a tubular pipe made of thin metal and its head is cut off at an acute angle like an injection needle to make a tip (2). ) And the crater back wall (4) that constitutes the crater (3), the flame (5) ignited continues burning while burning the crater back wall (4) and the tip (2) from the crater (3). Of.

[0007]

Since the present invention has been modified into the structure as described above, the following effects can be obtained.
Since the head of the nozzle made of a cylindrical pipe made of thin metal is cut off at an acute angle, the crater becomes elongated and elliptical and a crater back wall conforming to that shape is formed and a sharp tip is formed. Composed. Therefore, when the exhaust gas is ignited, the back wall of the crater formed along the crater wraps the flame and acts as a guide, and at the same time acts as a windbreak wall to protect the breeze. The absorption area is expanded to help the combustion of fire, and the sharp pointed end of the combustion accelerates and burns to promote complete combustion of the gas. Furthermore, even if the burnt tip is extinguished temporarily by vibration or slight wind, it will ignite quickly unless the tip is cooled, and the fine flame can continue burning by extinguishing and firing repeatedly.
