The present invention discloses a vortex combustion type mosquito coil combustion concentration control diffuser. The vortex combustion type mosquito-scented combustion concentration control diffuser of the present invention is provided in a cylindrical shape forming an accommodation space therein, but the lower body has an intake port through which air is introduced from the outside and the upper surface is opened, and the upper part of the lower body The upper body is formed connected to and is provided with a blower fan for forcibly inhaling air through an inlet and discharging it to the outside； A combustion case having a cylindrical shape with a coil-type mosquito repellent fixed on the bottom surface and an open cylindrical shape on the top surface, and a plurality of radially formed radially on the bottom surface of the combustion case. Each end of the lower vortex suction port and the lower vortex suction port is provided to shield the upper surface of the combustion case and the lower vortex blades that protrude toward the inner center to induce the incoming air to form a vortex. Combustion unit consisting of a damper control unit to guide flow to； The dilution case is fixed to the upper side of the combustion unit and forms a dilution chamber in which the upper part of the damper control unit is accommodated and the combustion gas is introduced. The user rotates by accommodating a dilution vortex blade and a dilution case inside a plurality of dilution vortex inlets through which air from the intake port flows in, and at one end of each of these dilution vortex inlets, a dilution vortex blade that induces the air flowing toward the inner center to cause a vortex. It consists of a dilution unit consisting of a control case in which a plurality of control holes are formed at intervals on the side to adjust the opening amount of the dilution vortex inlet by operation. The present invention constituted as described above is capable of improving combustion effi
