Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

As shown in fig. 1, the present invention does not disclose a double-layer air duct, which includes a duct body 1, wherein one end of the duct body 1 is a first butt end 2, and the other end of the duct body 1 is a second butt end, when two adjacent duct bodies 1 are connected, the first butt end 2 of one duct body 1 is butt-jointed with the second butt end 3 of the other duct body 1, and then the two adjacent duct bodies are fastened to realize the connection of the duct bodies 1. The utility model discloses in, a wind scooper 4 of the terminal surface fixedly connected with of first butt end 2, wind scooper 4 inserts in the second butt end 3 of another body 1 when connecting body 1, consequently, can set up wind scooper 4 and be the frustum of a cone shape to the diameter that makes wind scooper 4 increases in proper order to the direction that body 1 is close to first butt end 2 from the one end of keeping away from body 1 first butt end 2.

The utility model discloses in, as shown in fig. 3, wind scooper 4's distribution has the bloop 5 that runs through the wind scooper 4 inboard and outside on the surface, and bloop 5 adopts for the step hole to the step diameter of bloop 5 reduces from the outside of wind scooper 4 to the inboard gradually, when the air current was through bloop 5, because bloop 5 is gradually bigger at the ascending diameter of the flow direction of air current, therefore reduces the noise when the air current flows through bloop 5. Additionally, because the utility model discloses a wind scooper leads the air current in another body 1 from a body 1, and at this moment, the air current has avoided the butt joint of two bodies 1, that is to say, the air current can not flow through the butt joint of two bodies 1, therefore can not produce the noise through the butt joint of two bodies 1.

The utility model discloses in, when specifically setting up wind scooper 4, can be equipped with the clamping ring 6 that is used for with the 2 butt joints of first butt joint end at the big footpath end of wind scooper 4 to make wind scooper 4 and clamping ring 6 integrated into one piece, through this kind of structure, can effectively increase the area of connection of wind scooper 4 and first butt joint end 2, improved the installation intensity of wind scooper 4. In addition, when the connection ring 6 is installed, the connection ring 6 needs to be installed inside the first abutting end 2 so that the distance between the connection ring 6 and the end of the first abutting end 2 is greater than 0, and a retainer ring 12 which is engaged with the connection ring 6 is provided in the pipe body 1 to fix the connection ring 6. Specifically, the distance between the connecting ring 6 and the outer end of the first butt end 2 is 5-10 cm. The end face of the second abutting end 3 is provided with a pressing ring 7 for assembling with the connecting ring 6.

The utility model discloses in, as shown in fig. 1 and 2, the first flange 8 of tip fixedly connected with of first butt joint end 2, the tip fixedly connected with second flange 9 of second butt joint end 3, carry out the fastening through first flange 8 and second flange 9 between two adjacent bodys 1, be equipped with the first butt joint face 10 that is sinusoidal shape on the butt joint face of first flange 8, be equipped with first butt joint face 10 complex second butt joint face 11 on the butt joint face of second flange 9, through the setting of the first butt joint face 10 of curved and second butt joint face 11, can reduce the probability that the gas flow flows through the gap between first flange 8 and the second flange 9, thereby can further reduce the noise.
