Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioning accessories, and in particular relates to a low-noise DC silencer for air conditioning pipelines. Background Technology

[0002] In modern buildings and daily life, air conditioning systems have become an indispensable part, providing us with a comfortable indoor environment. However, with the widespread use of air conditioning systems, the noise generated during their operation has become increasingly prominent, becoming a significant factor affecting the quality of living and working environments. As an important component of air conditioning systems, the flow of air inside the air conditioning ducts is one of the main sources of noise. To address these issues, silencers have emerged.

[0003] However, mufflers currently on the market have some problems in actual use: First, traditional mufflers adopt an integrated design, which means that when a component in the muffler is damaged due to long-term use or needs to be cleaned regularly to maintain performance, users often have to replace the entire muffler. This not only increases maintenance costs but also wastes resources and reduces the economic efficiency of the product. Second, traditional mufflers often use a single silencing mechanism, resulting in poor silencing effect. Furthermore, the silencing effect of traditional mufflers is often fixed and difficult to adjust according to actual needs.

[0004] Therefore, it is essential to invent a low-noise DC silencer for air conditioning pipes. Summary of the Invention

[0005] The purpose of this invention is to provide a low-noise DC silencer for air conditioning pipelines, thereby solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a low-noise DC silencer for air conditioning pipelines, comprising an intake silencer pipe, a connecting pipe, a protrusion, and an exhaust silencer pipe. The intake end of the intake silencer pipe is fixed to the exhaust pipe of the air conditioning pipeline, and the exhaust end of the intake silencer pipe is threadedly connected to the connecting pipe. The other end of the connecting pipe is threadedly connected to the exhaust silencer pipe, wherein the other end of the exhaust silencer pipe is fixed to the intake pipe of the air conditioning pipeline. A protrusion is fixed to the outer surface of the connecting pipe.

[0008] Furthermore, the intake silencer pipe includes a first pipe body, a first baffle, sound-absorbing cotton, and a first cylinder. One end of the first pipe body is fixed to the exhaust pipe of the air conditioning pipe, and the other end of the first pipe body is connected to a connecting pipe by thread engagement. The first baffle is fixed inside the first pipe body by welding, wherein a through hole is opened in the middle of the first baffle, and sound-absorbing cotton is fixed on the side of the first baffle near the exhaust pipe of the air conditioning pipe. The first cylinder is fixed on the side of the first baffle away from the exhaust pipe of the air conditioning pipe, wherein the other end of the first cylinder is sealed, and several through holes are opened on the outer side of the first cylinder. With this arrangement, the sound-absorbing cotton and the first cylinder can absorb the noise generated by the gas.

[0009] Furthermore, the connecting pipe includes a second pipe body, a cross, an adjusting cylinder, and a reflector. The two ends of the second pipe body are respectively connected to the corresponding intake muffler and exhaust muffler by threaded engagement, and the outer side of the second pipe body is fixed with a protrusion by welding. The adjusting cylinder is fixed inside the second pipe body by the cross, and the adjusting cylinder is slidably disposed on the outer side of the first cylinder. Several reflectors are fixed to the inner wall of the second pipe body by welding. With this arrangement, the muffler effect of the first cylinder can be adjusted by the adjusting cylinder. In addition, the reflectors can guide some of the gas in the opposite direction to achieve gas counterflow, thereby achieving a muffler effect.

[0010] Furthermore, the exhaust muffler includes a third pipe, a second baffle, and a second cylinder. One end of the third pipe is connected to the second pipe via a threaded connection, and the other end of the third pipe is connected to the air intake pipe of the air conditioning system. The second baffle is fixed inside the third pipe by welding, and the second cylinder is fixed to the side of the second baffle near the connecting pipe by welding. The other end of the second cylinder is sealed, and the second cylinder is slidably disposed inside the adjusting sleeve. Several through holes are provided through the second cylinder. This arrangement enables the second cylinder to achieve a gas muffler effect, and the muffler effect of the second cylinder can be adjusted by adjusting the sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The intake muffler, connecting pipe and exhaust muffler of this utility model adopt a modular design. When a component is damaged or needs cleaning, it is not necessary to replace the entire muffler. Only the damaged or maintenance-required module needs to be operated, which greatly reduces maintenance costs and complexity.

[0013] 2. This utility model, through the arrangement of sound-absorbing cotton, a first cylinder, a reflector, and a second cylinder, can sequentially perform noise reduction treatment on the gas. The sound-absorbing cotton effectively absorbs the initial noise generated by the gas flow. The design of the first and second cylinders allows the gas to be dispersed and discharged when it passes through, further reducing noise. The reflector utilizes the principle of gas counterflow to consume gas energy and achieve additional noise reduction effect. These mechanisms work together to significantly improve the overall noise reduction performance of the silencer.

[0014] 3. By setting up an adjusting cylinder, this utility model can adjust the noise reduction effect of the adjusting cylinder on the first and second cylinders by adjusting the length of the thread engagement between the second tube body and the first and third cylinder bodies.
