The utility model relates to an intelligent electric heating mosquito repellent killer comprising a stock solution box, mosquito repellent liquid and an electric heating body, wherein the mosquito repellent liquid is arranged in the stock solution box. The mosquito repellent killer is characterized in that the electric heating body is internally provided with a longitudinal through hole; an adsorption cotton core is arranged in the through hole in which the mosquito repellent liquid is arranged; and an intelligent controller with functions of multi-speed temperature control, time switch control and working converting function is arranged on the stock solution box. The utility model has the advantages that the electric heating body which is internally arranged can meet the requirement of effective volatilization of the stock solution box by adjusting the resistance value, thereby changing the feasible surface temperature; and a plurality of temperature regulation gears are preset by the intelligent controller; a fan which is additionally arranged can effectively accelerate the volatilization of the mosquito repellent liquid and can rapidly diffuse the space to be mosquito-repelled; and the intelligent controller can realize time-sharing or continuous work, thereby the mosquito repelling and killing requirements in special environments are met.
