Efficient and energy-saving air heating furnace

The utility model relates to an efficient and energy-saving air heating furnace which comprises a machine body, one end of the machine body is fixedly connected with a combustor, one end of the machine body is fixedly connected with a chimney, the other end of the machine body is fixedly connected with a heating pipe head, one end of the machine body is fixedly connected with a motor, and a combustion chamber is arranged on the inner wall of the machine body. And the inner wall of the combustion chamber is fixedly connected with a heating pipe. Through the arrangement of the cleaning frame, the combustor can generate smoke during heating, soot is adhered to the outer wall of the heating pipe after long-term use, so that the heat conduction efficiency is reduced, the heating efficiency of heat exchange liquid is reduced, and the use effect is poor, and at the moment, the cleaning frame is driven by the control motor to scrape soot impurities adhered to the outer wall; and through arrangement of springs, it can
