The present invention discloses a dilution diffuser with a mosquito coil combustion concentration. The dilution diffuser for the concentration of combustion of mosquito coils of the present invention has a cylindrical shape that forms a combustion chamber, which is a space in which the mosquito coils are burned, and is supported by a plurality of legs to be positioned at a certain height on the ground, and an intake port through which air flows from the outside. Is formed, the bottom surface of the combustion unit is provided with a mosquito coil holder to support the coil-type mosquito coil； As a tube-shaped member disposed horizontally on the upper side of the combustion unit, one side is provided with a blowing unit that sucks air and blows air, and the other side is equipped with an expanded pipe having an expanded diameter to discharge sucked air. Exhaust unit； 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 for mosquito scented smoke to flow into the inside of the exhaust unit. It consists of a dilution chamber provided with a plurality of nozzles that can be sucked in by a car. The present invention configured as described above is guided to the inside of the exhaust unit by the pressure difference between the mosquito scent combusted in the combustion chamber and mixed and diluted with external air, thereby lowering the concentration of the chemical components contained in the scent of the mosquito scent, and consequently included in the mosquito scent. It is possible to minimize the damage caused by excessive exposure of harmful components to the human body, and in particular, it has a useful effect to increase the effectiveness of mosquito repellent because it can diffusely distribute mosquito-scented smoke of a uniform concentration over a relatively large space using a blower unit.
