Abstract
The utility model discloses a movable flue structure which comprises a flue fixing plate fixedly arranged in a combustion chamber, a first smoke flow channel is arranged between the flue fixing plate and the top of a combustion inner frame, a second smoke flow channel communicated with the first smoke flow channel is arranged between the flue fixing plate and a fireplace door, and a third smoke flow channel is arranged on the flue fixing plate. A flue moving part used for sealing or opening the third smoke flow channel is movably arranged at the third smoke flow channel, a flue connecting part is arranged at the upper end of the flue moving part, an ejector rod is arranged in the combustion chamber, one end of the ejector rod abuts against the flue connecting part, and the other end of the ejector rod is connected with the fireplace door. According to the wood-fired fireplace, through conversion between direct exhaust and non-direct exhaust of smoke, no obvious smoke is generated at any stage in the using process of the wood-fired fireplace, and environment protection is facilitated; and when the ejector rod does not eject the flue moving part, the flue moving part falls down through gravity to seal the third smoke flow channel, so that opening and closing are more convenient and simpler.
