[0019] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a noise reduction device for a copper collecting pipe, including a pipe body 1. The pipe body 1 includes a first pipe section 5, a second pipe section 6 and a third pipe section 7. The first pipe section 5, the second pipe section 6 and the third pipe section 7 are fixedly connected in sequence. The cross-sectional shape of the first pipe section 5 is "T" shaped. A flow dividing plate 8 is fixedly arranged inside one end of the first pipe section 5. Reflective sound insulation coatings 4 are arranged on the inner walls of the first pipe section 5, the second pipe section 6 and the third pipe section 7. The first pipe section 5, the second pipe section 6 and the third pipe section 7 are all made of copper. By setting the first pipe section 5, the second pipe section 6 and the third pipe section 7, the diameter of the second pipe section 6 is smaller, which can stabilize the air pressure and decompose part of the air pulse, so that the third pipe section 7 can buffer the air pulse and suppress the generation of noise.

[0021] In this embodiment, the diameter specification of the left end of the first pipe section 5 is smaller than that of the right end. An arc-shaped surface is arranged at the connection of both ends of the first pipe section 5. The number of the second pipe sections 6 is four. One end of the second pipe section 6 is arranged on one side of the flow dividing plate 8. A flow dividing plate 8 is fixedly arranged at one end inside the third pipe section 7. The diameter specification of the third pipe section 7 is larger than that of the first pipe section 5. The arranged flow dividing plate 8 and the first pipe section 5 can separate the air pulse, and continue to buffer and reduce the air pulse through the increase of the diameter of the third pipe section 7, which is convenient for suppressing the generation of noise.

[0022] In this embodiment, one end of the first pipe section 5 and the opposite end of the third pipe section 7 are in the shape of a frustum of a cone. The second pipe section 6 is fixedly arranged between the frustums of the cone. The pipe body 1 forms a depression through the arrangement of the second pipe section 6, which is convenient for fixing the pipe body 1 through the depression position.

[0023] In this embodiment, a sound-absorbing cotton layer 3 is fixedly arranged on the outside of the pipe body 1. The sound-absorbing cotton layer 3 is attached to the outer wall of the pipe body 1. A rubber layer 2 is adhesively arranged on the outside of the sound-absorbing cotton layer 3. The arranged sound-absorbing cotton layer 3 can absorb the noise conducted by the pipe body 1, and the rubber layer 2 can insulate and reduce the noise of the pipe body 1, improving the sound insulation and noise reduction effect of the device. And through the rubber layer 2 and the sound-absorbing cotton layer 3, shock absorption can be carried out during installation.

[0024] When using the noise reduction device for the red copper collecting pipe, the first pipe section 5, the second pipe section 6 and the third pipe section 7 are fixedly welded in sequence. The diameter of the right end of the first pipe section 5 becomes larger, which can buffer the air intake, and the air is shunted into the interior of the second pipe section 6 through the shunt plate 8. The diameter of the second pipe section 6 is smaller, which can stabilize the air pressure. The diameter of the third pipe section 7 is larger, so that the third pipe section 7 can continue to buffer the air pulse, thereby suppressing the generation of noise. And by setting the reflective sound insulation coating 4 on the inner walls of the first pipe section 5, the second pipe section 6 and the third pipe section 7, it is convenient to reflect the noise generated by the air pulse through the reflective sound insulation coating 4 and block the transmission of noise to the outside. By setting the sound-absorbing cotton layer 3 and the rubber layer 2, it is convenient to insulate and dampen the pipe body 1, thereby reducing the noise of the indoor unit of the air conditioner. The depression on the outside of the second pipe section 6 is convenient for installing the pipe body 1, and the pipe body 1 is insulated and damped by the sound-absorbing cotton layer 3 and the rubber layer 2.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
