The present invention discloses a vortex-burning type mosquito-fuel concentration-controlled diffuser. The vortex-burning type mosquito-combustion concentration-controlled diffuser of the present invention is provided in a cylindrical shape forming an accommodating space therein, however, a lower body having an intake port through which air is introduced from the outside and an upper surface is opened; 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. A combustion vortex suction port formed to flow through and provided at one end of each of the combustion vortex suction ports, and a combustion vortex wing which induces the inflow of air to cause vortex by extending protruding toward the inner center and is located on the upper surface of the combustion case A combustion unit provided with a shield and made of a damper control unit for guiding flow of combustion gas in a lateral direction; It is connected to the upper part of the lower body, and the dilution unit is installed inside. The upper case has a cylindrical upper case with the upper and lower surfaces open, and the upper side of the upper case is provided in a ring shape so that the combustion gas discharged forms an upward air stream. As it proceeds to the outside, the discharge flange having an upwardly inclined angle is supported and spaced apart by a plurality of support posts on the top of the discharge flange to form an outlet through which combustion gas is discharged. The upper body made of a discharge guide installed with a centrifugal blower fan to discharge the combustion gas through the outlet located in; It is fixed on the upper side of the combustion unit and the upper portion of the damper control part is accommodat
