Burner having fuel control part

A burner having a fuel control part, comprising:

• an adaptor to which a fuel supply box for supplying fuel is connected, and having a fuel inlet;
• a combustion part configured to perform combustion while fuel injected from the fuel inlet is discharged through a flow path;
• a connection housing disposed between the adaptor and the combustion part, having a fuel supply path communicated with the fuel inlet and the flow path and configured to feed fuel of the fuel supply box to the combustion part;
• an inflow fuel control part provided at one side of the connection housing, the inflow fuel control part composed of a coupling member and a spindle being coupled to the coupling member, the coupling member protruding toward one side of the connection housing, and forming a communication space part and the spindle accommodated in the communication space part and having a tapered formed one end inserted in the fuel supply path configured to gradually control an opening degree of the fuel inlet by controlling a distance between the fuel inlet and the spindle, thereby controlling the amount of fuel injected into the fuel supply path;
• and
• a feed fuel control part provided at another side of the connection housing, the feed fuel control part including a pressure interworking valve composed of a pressing part and a head part extending from the pressing part, a return spring for returning the pressure interworking valve to an initial position when the pressure is released and an elastic control knob connected to one end of the return spring to control elasticity of the return spring, the head part being disposed inside the fuel supply path and having a tapered part formed on a circumferential surface thereof, the tapered part having a diameter gradually decreased toward a fuel flow direction, and the pressure interworking valve being configured to gradually move in the fuel flow direction when a pressure is applied into the fuel supply path by the fuel injected into the fuel supply path and thus control the amount of fuel supplied to the combustion part by controlling an open degree of the fuel supply path by the tapered part.
