The present invention discloses a mosquito coil vortex combustion-induced concentration controlled diffuser. The mosquito-directed vortex combustion-induced concentration-controlled 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 certain height on the ground, and a suction port through which air flows from outside at the bottom. Body unit is formed； The body unit is detachably provided inside, and the coil-like mosquito coil is fixed to the bottom surface, the upper surface has an open cylindrical shape, and the bottom surface is formed with a plurality of radial vortex intakes formed in a rim direction from the center to a radial direction. A combustion unit having a lower surface vortex blade protrudingly formed at each end of each lower surface vortex suction port to induce air flowing toward an 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 surround the outer circumferential surface of the exhaust unit so that a space is formed therein, and is connected to the 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 into the exhaust unit. A dilution chamber provided with a plurality of nozzles capable of being sucked in by a pressure difference； Consists of a concentration control unit having a valve pipe connected to the side of the connection pipe to form a passage through which external air flows, and a rotation control plate installed on the valve pipe to control the amount of opening and clos
