PURPOSE: A straight exhaust pipe and an exhaust pipe using the straight exhaust pipe are provided to continuously and periodically clean the inner surface of the exhaust pipe including the straight exhaust pipe with a brush rotated by a motor, thereby preventing the degradation of ventilation performance or the blockage of the exhaust pipe even in a long-term usage. CONSTITUTION: A straight exhaust pipe and an exhaust pipe (1) using the straight exhaust pipe include a connection straight pipe (11), bearing brackets, a rotary shaft (S), and a brush unit (5). A connection pipe (12) is arranged on the periphery of the connection straight pipe. A flange is formed on the periphery of both sides of the connection straight pipe. The bearing brackets are installed on both sides of the connection straight pipe. A bearing is mounted on the center of the bearing bracket. A plurality of exhaust gas through-holes (42) is formed on the periphery of the bearing bracket. A rectangular groove and a rectangular shaft are formed on one end and the other end of the rotary shaft. The brush unit separates foreign materials adsorbed on the inner surface of the connection straight pipe by the rotation of the rotary shaft. |
