[0002] At present, the kitchen flue and bathroom exhaust duct are concrete walls with prefabricated flues on the top, which require a large site, consume a lot of labor, and occupy construction time. After the installation of the prefabricated flue, the workload of protecting the finished product is large (because there are other professional constructions on the roof, such as air duct installation, which will damage the installed flue and cause damage to the four corners), and it also has a certain impact on the roof construction load; the finished flue relies on the chimney effect and natural exhaust. It is open on all sides, which can easily cause backflow, and even cause rain leakage in the flue when it is windy and rainy. Utility Model Content

[0003] The purpose of the utility model is to provide a blocking device above the flue in a kitchen or bathroom to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blocking device above the kitchen and bathroom flue, comprising an aluminum plate covering a concrete shaft, the aluminum plate being fixed to the top of the concrete shaft by rivets on all sides, and a non-powered turbine-type ventilation hood being connected to the top of the aluminum plate, and the non-powered turbine-type ventilation hood being communicated with the concrete shaft.

[0005] Preferably, the aluminum plate has a bent structure around it, and the bent structure around the aluminum plate is clamped on the flanges around the top of the concrete flue, and a sealant is provided at the connection between the aluminum plate and the concrete flue.

[0006] Preferably, a hole is opened at the center of the top of the aluminum plate, and the unpowered turbine type ventilating hood is installed on the hole, and sealant is provided around the unpowered turbine type ventilating hood and at the inner wall of the hole.

[0007] Preferably, the thickness of the aluminum plate is 5 mm.

[0008] Preferably, the cross-section of the unpowered turbine-type ventilating hood is a circular structure.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The flue sealing device of aluminum plate can achieve the effect of smooth exhaust of the entire exhaust flue. Through this sealing device, pipeline construction can be directly constructed. This aluminum plate sealing device saves a lot of space for material stacking on the construction site and saves the workload of finished product protection. It not only ensures the flue exhaust effect, but also has obvious economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS
