The present invention discloses a mosquito coil vortex combustion type concentration-controlled diffuser. The mosquito coil vortex combustion type concentration-controlled diffuser of the present invention is provided in a cylindrical shape to form 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. The upper body is formed to be connected to the upper side is provided with a blowing fan for forcing air through the suction port and discharged to the outside； Arranged on the inner lower side of the lower body to form a combustion chamber in which mosquito coils are burned, the coil-type mosquito coil is fixed to the bottom surface, and the upper surface is a combustion case having an open cylindrical shape, and air is supplied through the intake port to the side of the combustion case. Combustion vortex inlets formed through the inflow and combustion vortex blades provided at one end of each of the combustion vortex intakes to induce air to flow into the inner center to cause vortex, and are located on the upper surface of the combustion case to be shielded for combustion Combustion unit consisting of a damper control unit for guiding the gas in the lateral direction； 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 oper
