Referring to fig. 1-2, an air volume damper, installed on a sidewall of an oil smoke pipeline, comprises:

the driving motor 100 is directly fixed on the outer wall of the oil smoke pipeline;

the damping fan blade 200 is rotatably arranged in the oil smoke pipeline through the rotating shaft 300;

the rotating shaft 300 penetrates through the oil smoke pipeline, the driving motor 100 drives the rotating shaft 300 to rotate through a transmission piece, and the damping fan blade 200 and the rotating shaft 300 synchronously rotate. The rotating shaft 300 is rotatably mounted on the oil smoke pipeline through a bearing assembly, and the bearing assembly is used for fixing the rotating shaft 300 on one hand and can also be used for fixing the damping fan blade 200 on the other hand so as to prevent shaking. Through installing in the branch pipe that oil smoke pipeline and petticoat pipe are connected the amount of wind attenuator, when the amount of wind of the petticoat pipe that needs to be adjusted corresponding, driving motor 100 drives damping flabellum 200 through pivot 300 and rotates, adjusts the clearance of oil smoke pipeline to realize the independent air regulation of a plurality of petticoat pipes of commercial integrated petticoat pipe.

In this embodiment, notches for accommodating the bearing assembly are provided at two ends of the damping fan blade 200. The damping fan blade 200 is attached to the inner wall of the oil smoke pipeline as much as possible, so that the air quantity control effect is ensured.

Referring to fig. 3, in this embodiment, the bearing assembly includes a seal 500 to prevent oil smoke from escaping from the installation site. The tightness of the oil smoke pipeline is ensured.

In this embodiment, the damping fan blade 200 includes a first fan blade 210 and a second fan blade 220, where the first fan blade 210 and the second fan blade 220 are sleeved on the rotating shaft 300 and can slide along the rotating shaft 300;

the first fan blade 210 and the second fan blade 220 are provided with an adjusting chute 400, the first fan blade 210 and the second fan blade 220 are provided with an adjusting chute 400 to align, and an elastic bolt is arranged in the adjusting chute 400. In the commercial field, the fume duct is typically mounted at the ceiling. However, the ceiling has a limited installation height, so when the maximum air volume requirements at different fume ducts are not uniform, the heights of the fume ducts are uniform, differing in the widths of the fume ducts. And in order to ensure the universality of the damping fan blade 200, the damping fan blade 200 needs to have a length adjusting function so as to adapt to the oil smoke pipelines with different widths. When the length of the damping fan blade 200 needs to be adjusted, the elastic bolt is loosened, and the first fan blade 210 and the second fan blade 220 are pulled to the designated length, so that the damping fan blade is fixed by tightening the locking bolt. The adjusting chute 400 at the overlapping position of the first blade 210 and the second blade 220 is used for adjusting the length of the damper blade 200.

Referring to fig. 4, in this embodiment, the damping fan blade 200 is rectangular, and the first fan blade 210 and the second fan blade 220 are rectangular. For a fume duct with a rectangular cross section, rectangular damping fan blades 200 may be used.

Referring to fig. 5, in this embodiment, the damping fan blade 200 is circular, and the first fan blade 210 and the second fan blade 220 are semicircular. For the oil smoke pipeline with a circular cross section, a circular damping fan blade 200 can be adopted, wherein in order to ensure adjustability, the circular damping fan blade 200 is formed by splicing a first fan blade 210 and a second fan blade 220 which are in a semicircular rectangular shape.

In this embodiment, the transmission member is a reduction gear assembly. To ensure the progress of adjustment and the strength of torque, the driving motor 100 drives the rotation shaft 300 to rotate through a reduction gear set.

An oil smoke pipeline comprises the air quantity damper. The oil smoke pipeline is formed by splicing one section, and in actual installation, the air quantity damper is fixed in the oil smoke pipeline, and then the oil smoke pipeline with the air quantity damper is installed at a designated position.

In practical use, in order to make the air quantity adjustment more intelligent, a smoke sensor and a temperature sensor are often matched. During cooking, the temperature under the hood/ventilation ceiling may rise and steam or smoke may be generated. The sensor detects changes in smoke and temperature and adjusts the speed of the fan and damper as needed to maintain optimal air quality. Once the temperature returns to normal, all fumes and vapors disappear, the system returns the ventilation to a preset low level, preventing unnecessary heat loss by adjusting the fan speed and adjusting the damper.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
