The air duct assembly 100 can improve the smoothness of the air flow, thereby reducing the noise generated when the air flow passes through the air duct.

It should be noted that the air duct assembly 100 may be used in a hair dryer, particularly an axial flow hair dryer, to improve the smoothness of the air flow through the air duct assembly 100, so as to reduce the noise generated when the air flow passes through the air duct, thereby solving the problem of the prior art that the axial flow hair dryer has a relatively large noise.

Specifically, as shown in fig. 1, fig. 2 and fig. 4, this air duct assembly 100 includes an air duct 10 and an air outlet duct 20, and as the name suggests, the air duct 10 and the air outlet duct 20 are both cylindrical structures, and the cylindrical structures have the structural characteristics of hollow inside, and meanwhile, both ends of the cylindrical structures both have openings, and both openings can communicate with the hollow structure inside each other.

For convenience of distinction and understanding, the two openings of the air guiding duct 10 are respectively referred to as the air inlet of the air guiding duct 10 and the air outlet of the air guiding duct 10, and similarly, the two openings of the air outlet duct 20 are respectively referred to as the air inlet of the air outlet duct 20 and the air outlet of the air outlet duct 20.

On the basis, as shown in fig. 1, fig. 2 and fig. 4, one end of the air duct 10 is fixedly connected to the air outlet duct 20, in other words, the air outlet of the air duct 10 is fixedly connected to the air inlet of the air outlet duct 20, so that the air flow can flow into the air duct 10 through the air inlet of the air duct 10, flow into the air outlet duct 20 through the air outlet of the air duct 10 and the air inlet of the air outlet duct 20, and finally flow out through the air outlet of the air outlet duct 20.

In addition, as shown in fig. 1 to 4, the air duct assembly 100 further includes a wind scooper 30, the wind scooper 30 includes a small diameter end 31 and a large diameter end 32, and as the name suggests, the diameters of the two ends of the wind scooper 30 are not equal, wherein one end has a smaller diameter, which is called the small diameter end 31, and the other end has a larger diameter, which is called the large diameter end 32. The actual dimensions of the small-diameter end 31 and the large-diameter end 32 are not particularly limited, and those skilled in the art should be able to make appropriate selections and designs according to the actual conditions.

On the basis, as shown in fig. 1 to 4, the wind scooper 30 is fixedly connected to an end of the wind guiding barrel 10 away from the wind outlet barrel 20 through the small diameter end 31, in other words, the small diameter end 31 of the wind scooper 30 is fixedly connected to the wind inlet of the wind guiding barrel 10, and the large diameter end 32 is used for being fixedly connected to the wind inlet barrel of the hair dryer, so that the airflow can flow into the wind guiding barrel 10 through the wind inlet barrel under the action of the wind scooper 30.

Because the wind scooper 30 includes the small diameter end 31 and the large diameter end 32, and the diameter of the large diameter end 32 is large, the effect of gradually gathering together can be achieved, and the diameter of the small diameter end 31 is small, the effect of flow direction limiting can be achieved, therefore, under the effect of the wind scooper 30, the airflow can flow more smoothly, and the noise generated when the airflow flows through the air duct is reduced.

As described above, the air duct assembly 100 includes the air duct 10, the air outlet duct 20 and the air guiding cover 30, one end of the air duct 10 is fixedly connected to the air outlet duct 20, so that the airflow can flow into the air duct 10 through the air inlet of the air duct 10, flow into the air outlet duct 20 through the air outlet of the air duct 10 and the air inlet of the air outlet duct 20, and finally flow out through the air outlet of the air outlet duct 20, the air guiding cover 30 includes the small diameter end 31 and the large diameter end 32, the air guiding cover 30 is fixedly connected to one end of the air duct 10 far from the air outlet duct 20 through the small diameter end 31, and the large diameter end 32 is used for being fixedly connected to the air inlet duct of the hair dryer, so that the airflow can flow into the air duct 10 through the air inlet duct under the action of the air guiding cover 30. Because the wind scooper 30 includes the small diameter end 31 and the large diameter end 32, and the diameter of the large diameter end 32 is large, the effect of gradually gathering together can be achieved, and the diameter of the small diameter end 31 is small, the effect of flow direction limiting can be achieved, therefore, under the effect of the wind scooper 30, the airflow can flow more smoothly, and the noise generated when the airflow flows through the air duct is reduced.

As shown in fig. 2 and 4, in the present embodiment, the cross-sectional shape of the air guiding cover 30 is a circular arc, and the circular arc is convex toward the axis of the air guiding duct 10. In short, the wind scooper 30 is in a trumpet shape, so that the air flow is guided into the wind guiding tube 10 more smoothly by utilizing the gradually converging structural characteristics of the trumpet shape.

As shown in fig. 1 to 4, in the present embodiment, a wind guiding blade 33 is disposed on a side of the wind guiding cover 30 close to the large diameter end 32, and the wind guiding blade 33 extends along a direction from the small diameter end 31 to the large diameter end 32. The extending direction of the wind guide blades 33 is adapted to the flowing direction of the airflow, so that the gathering and guiding effects of the wind scooper 30 on the airflow are improved through the wind guide blades 33.

As shown in fig. 3 and 4, in the present embodiment, the cross-sectional shape of the air guiding blade 33 is spiral, and the spiral rotating direction is matched with the rotating direction of the blade of the blower, so as to further improve the guiding effect of the air guiding blade 33 on the flowing direction of the air flow when the air flow passes through the air guiding cover 30, and thus the air flow can flow into the air guiding duct 10 more smoothly under the effect of the blade.

As shown in fig. 1 and 4, in the present embodiment, the diameter of the wind guide blade 33 near the small diameter end 31 is smaller than the diameter of the wind guide blade 33 near the large diameter end 32, so as to adapt to different structural characteristics of the small diameter end 31 and the large diameter end 32 of the wind scooper 30, and to guide the airflow into the wind scooper 10 more smoothly.

As shown in fig. 1 to 4, in the present embodiment, the wind guide blade 33 includes a plurality of wind guide blades 33, and the plurality of wind guide blades 33 are arranged at intervals along the circumferential direction of the wind scooper 30. Preferably, the plurality of wind guide blades 33 are uniformly distributed along the circumferential direction of the wind scooper 30.

Regarding the actual number of the guide vanes 33 and the distance between two adjacent guide vanes 33, those skilled in the art should be able to make reasonable selection and design according to the actual situation, and no specific limitation is made here.

As shown in fig. 3 and 4, in the present embodiment, a motor 40 and a fan blade 50 are disposed in the air duct 10, the fan blade 50 is mounted on an output shaft of the motor 40, and the fan blade 50 is located at a side of the motor 40 close to the air guiding cover 30, so that the motor 40 drives the fan blade 50 to rotate, thereby changing air pressures at two sides of the fan blade 50, and further introducing an air flow into the air duct 10.

As shown in fig. 2 and 4, in the present embodiment, the diameter of the end of the exhaust air duct 20 close to the air guiding duct 10 is larger than the diameter of the end of the exhaust air duct 20 far from the air guiding duct 10. In other words, the diameter of the air inlet of the air-out cylinder 20 is larger than the diameter of the air-out cylinder 20, so as to improve the wind force when the airflow flows out through the air outlet of the air-out cylinder 20, thereby improving the operation effect of blowing away the impurities on the ground.
