Diesel filter with safe heating function

The utility model relates to the technical field of diesel filters, and discloses a diesel filter with a safe heating function, which comprises a filter shell, a mounting shell fixedly mounted on the outer surface of the filter shell, and a cover fixedly mounted at the top of the filter shell. According to the diesel oil filter with the safe heating function, the heating pieces are distributed on the outer surface of the filter shell, the conduction plate can be heated, heat is transmitted by the conduction plate, the filter shell is indirectly heated, and the situation that the heating pieces make direct contact with the filter shell, so that the filter shell is scalded is avoided; the conduction plates are evenly distributed on the outer surface of the filter shell, it can be guaranteed that the filter shell is evenly heated, meanwhile, the temperature sensor can detect the temperature in the filter shell, the pressure sensor can detect the pressure in the filter shell, the heating piece is properly control
