The present invention discloses a mosquito coil vortex combustion-induced dilution diffuser. The mosquito coil vortex combustion-induced dilution diffuser of the present invention has a cylindrical shape that forms an accommodation space therein, and is provided with a plurality of support legs to be positioned at a predetermined height on the ground, and a suction port through which air flows from the outside is provided at the bottom. A main body unit formed; The body unit is detachably provided inside, and a coil-like mosquito coil is fixed on the bottom surface, and an upper surface has a cylindrical shape, and a plurality of vortex suction ports are formed at intervals on the outer surface, and one end of each of the vortex suction ports is formed. A combustion unit equipped with a vortex wing that induces air flowing into the inner center to form a vortex; It is a tube-shaped member with a front and rear surfaces arranged horizontally on the upper part of the combustion unit, and on one side there is a blowing unit that sucks air to perform a blowing action, and on the other side it gradually increases to discharge the sucked air. Exhaust unit having an expansion portion having a diameter expanded; It is provided to wrap the outer circumferential surface of the exhaust unit so that a space is formed therein, and is connected to an upper portion of the combustion unit through a connection pipe to provide a space through which mosquito scent smoke flows in, and the flow of mosquito scent smoke into the exhaust unit. It is composed of a dilution chamber provided with a plurality of nozzles to be sucked in by a pressure difference. The present invention is configured as described above, the mosquito coil vortex combustion-induced dilution diffuser improves the combustion efficiency while the air flowing into the combustion unit causes vortex, and the burned mosquito coil is induced into the exhaust unit by the air pressure difference. Since the concentration of ch
