The present invention discloses a vortex-burning type mosquito-fuel concentration-controlled diffuser. The vortex-burning type mosquito-repellent combustion concentration-controlled diffuser of the present invention is provided in a cylindrical shape that forms an accommodation space therein, but the lower body is formed with an inlet through which air is introduced from the outside, and an upper surface is opened, and an upper portion of the lower body is opened. It is formed to be connected to the upper side of the upper body is provided with a blowing fan for forcing air through the suction port and discharged to the outside； It is provided detachably inside the main body unit, and a coil-like mosquito coil is fixed on the bottom surface, and a combustion case having an open cylindrical shape is formed on the bottom surface, and a plurality of radial shapes are formed on the bottom surface of the combustion case. The long formed vortex intake and each one of these lower vortex intakes are provided to shield the upper surface of the combustion case and the vortex blades to induce the air that protrudes toward the inner center to induce air to form a vortex. Combustion unit consisting of a damper control unit for guiding flow； It is fixed to the upper side of the combustion unit and the upper portion of the damper control part is accommodated therein to form a dilution chamber into which combustion gas flows. The user's rotation by accommodating a plurality of dilution vortex inlets through which the air in the intake port flows, and dilution vortex blades and dilution cases that induce air into the inner center at one end of each dilution vortex intake to cause vortex. It is composed of a dilution unit consisting of a control case in which a plurality of control holes are formed at intervals on the side to control the opening amount of the dilution vortex intake under operation. The present invention configured as described above is capable of improving combustion
