At the same time, the bearing can make the turbine spiral baffle automatically rotate on the connecting rod, resulting in a strong exhaust effect, improving the smoke exhaust effect, reducing noise, increasing suction, and saving costs.

[0006] Preferably, a sealing rubber ring is provided at one end of the edge of the turbine spiral baffle that contacts the boss of the main tube; the sealing rubber ring plays a sealing role to prevent the gas from returning.

[0007] Preferably, the connecting assembly includes a connecting head, which is located at the right end of 2, and the right end of the connecting head is provided with a plug-in slot of various diameters; the connecting head can be adapted to the diameters of smoke pipes of different range hoods, thereby improving applicability.

[0016] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0017] like Figures 1 to 5As shown, the right end of the mounting seat 1 is fixedly installed with a main body tube 2, the interior of the main body tube 2 is hollow, the inner diameter of the right end of the main body tube 2 is smaller than that of the left end, and multiple support frames 3 are axially and evenly installed at the inner left end of the main body tube 2, the vertical tube 4 is fixedly installed on the support frame 3, and a spring 5 is installed inside the vertical tube 4. The connecting rod 6 is slidably installed inside the vertical tube 4, and a boss is provided at the left end of the connecting rod 6. The right end of the connecting rod 6 is rotatably installed with a bearing 8 through a bearing 8. The right end of the main body tube 2 is provided with a boss matching the turbine spiral baffle 7, and a sealing rubber ring 9 is provided at the end where the edge of the turbine spiral baffle 7 contacts the boss of the main tube 2. The connector 10 is located at the right end of 2, and the right end of the connector 10 is provided with plug-in slots of various diameters. Mounting holes are provided at the four corners of the mounting seat 1, and two mounting blocks 11 are relatively installed inside the mounting seat 1, and the mounting blocks 11 are provided with fixing holes.

[0018] When the range hood is exhausting, the force of the smoke moving forward pushes the turbine spiral baffle 7 to move, and compresses the spring 5 through the connecting rod 6 to make the main tube 2 pass through. At the same time, the bearing 8 can make the turbine spiral baffle 7 automatically rotate on the connecting rod 6, producing a strong exhaust effect, improving the smoke exhaust effect, reducing noise, increasing suction, and saving costs. The sealing rubber ring 9 plays a sealing role to prevent the gas from returning. The connector 10 can be applied to the smoke pipe diameters of different range hoods, improving applicability. It is convenient to fix it to the wall through the installation hole and fixing hole, thereby improving the convenience during installation.
