When the boiler is working, the flue gas it produces needs to be discharged through the flue.

[0003] The publication number authorized by China is CN215336424U, and it is named a patent for a boiler flue. The device includes a base, a smoke exhaust pipe and an inner cavity. A main body is fixed on the top of the base, and a smoke inlet is arranged at the bottom end of one side of the main body. A smoke exhaust pipe is fixed on the top of the other side of the main body, a filtering structure is arranged on one side of the smoke exhaust pipe, and an ash exhaust pipe is arranged at the bottom end of the smoke exhaust pipe.

[0006] 2. The device does not have a protective mechanism. When it is working, people nearby may be easily burned by accidentally touching the surface of the device.

[0007] In view of the above situation, technical innovation is carried out on the basis of the existing boiler flue. Utility Model Content

[0008] The purpose of the utility model is to provide a multifunctional flue to solve the problems raised in the above background technology.
