The invention discloses an electric warming fan convenient to adjust. The fan comprises a fixed frame, a positive and negative rotation motor is fixedly connected to the inner bottom wall of the fixedframe, the output end of the positive and negative rotation motor is fixedly connected with a thread rod, two symmetric sliding rails are fixedly connected to the inner wall of the fixed frame, firstsliding blocks are clamped into the sliding rails, one ends, away from the sliding rails, of the first sliding blocks are fixedly connected with first sliding rods, one ends, away from the first sliding blocks, of the first sliding rods are fixedly connected with pushing blocks, the end, away from the positive and negative rotation motor, of the thread rod penetrates the pushing blocks and extends into the pushing blocks, a pushing plate is fixedly connected to the upper surfaces of the pushing blocks, the side face, away from the pushing blocks, of the pushing plate is fixedly connected withan electric warming fan body, and a through groove is formed in the inner top wall of the fixed frame. According to the electric warming fan convenient to adjust, through structure cooperation, height adjusting of the electric warming fan can be achieved, use value of the electric warming fan is improved, and the fan is widely popularized.
