The utility model discloses an automatic demisting device of a headlamp of an automobile, at least one first gas path is arranged between the middle part of a main gas inlet pipe of an engine and the headlamp, and each first gas path and a second gas path in the headlamp form an automatic demisting gas path; the part, connected with the main air inlet pipe, of the first air path is a rigid first air guide pipe, and the included angle between the airflow direction of the first air guide pipe and the airflow direction of the main air inlet pipe ranges from 0 degree to 90 degrees. Through the arrangement of the included angle between the first air guide pipe and the main air inlet pipe, high-speed air of the automobile main air inlet pipe automatically drives airflow between the headlamp and the main air inlet pipe to move, exchange of outside air and moisture in the headlamp is achieved, the water vapor content in the lamp is reduced, the demisting function is achieved, and the difficulty of space arrangement a
