[0002] A fireplace is an indoor heating device that is independent or built into a wall. It uses combustible materials as energy and has a chimney inside. It originated from the heating facilities of Western homes or palaces and has been modernized. Usually, the installation of a fireplace depends on the structure of the house itself. The use of a fireplace requires supporting smoke exhaust equipment to exhaust the smoke generated by the combustion in the fireplace to the outside.

[0003] After searching, the patent with application number CN202020665922.5 discloses a smoke exhaust structure for a fireplace, which can adjust the height of the smoke exhaust pipe. However, the existing fireplace exhaust pipe is a single pipe, and the smoke generated is discharged upward under the action of hot air, but the natural smoke exhaust speed is slow. When the fireplace is just ignited, a large amount of smoke will be generated. If it cannot be discharged in time, it will spread to the entire room and endanger the health of the users. Therefore, an efficient auxiliary smoke exhaust structure for a fireplace is proposed. Utility Model Content
