[0024] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0025] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0027] This application provides a vibration damping device and an air conditioner to solve the problem of noise caused by pipe vibration. The following description will be provided in conjunction with the accompanying drawings.

[0028] Please see Figure 1 and Figure 2 This application provides a shock absorption device, including a shock absorption counterweight. The shock absorption counterweight has a receiving cavity, and a wave deflector 3 is provided on the cavity wall. At least part of the wave deflector 3 is deformable. The wave deflector 3 and the cavity wall together form a buffer channel 4, and the buffer channel 4 is filled with damping fluid.

[0029] The vibration damping device provided in this application embodiment clamps the vibration damping counterweight onto the vibrating pipe. When the pipe vibration is transmitted to the vibration damping counterweight, the damping fluid first absorbs the vibration energy. Part of the vibration mechanical energy is converted into the internal energy of the damping fluid, and the remaining vibration mechanical energy is converted into the kinetic energy of the damping fluid. This causes the damping fluid to tumble and generate a surge in the buffer channel. The surge impacts the baffle plate 3, causing at least part of the baffle plate 3 to deform. The kinetic energy of the damping fluid is converted into the internal energy of the baffle plate 3, thereby reducing the vibration of the pipe and solving the problem of noise generated by pipe vibration.

[0030] Please see Figure 1 and Figure 2 The shock-absorbing counterweights include a first shock-absorbing counterweight 1 and a second shock-absorbing counterweight 2. In this embodiment, the first shock-absorbing counterweight 1 and the second shock-absorbing counterweight 2 are made entirely of rubber. In other embodiments of this application, a buffer layer is provided on the first shock-absorbing counterweight 1 and the second shock-absorbing counterweight 2. The buffer layer covers the surface of the first shock-absorbing counterweight 1 and the surface of the second shock-absorbing counterweight 2, and the buffer layer is made of rubber.

[0031] Please see Figure 1 and Figure 2 The first shock-absorbing counterweight 1 has a connecting portion 12 on the side near the second shock-absorbing counterweight 2, and the second shock-absorbing counterweight 2 has a connecting portion 22 on the side near the first shock-absorbing counterweight 1. The connecting portion 22 has a connecting groove 221 that mates with the connecting portion 12. When the first shock-absorbing counterweight 1 and the second shock-absorbing counterweight 2 are connected, the connecting portion 12 is positioned in the connecting groove 221, and the groove wall of the connecting groove 221 abuts against and fits against the outer wall of the connecting portion 12. The side wall of the first shock-absorbing counterweight 1 has a first mounting opening 13 that communicates with a first pipe hole 11, and the side wall of the second shock-absorbing counterweight 2 has a second mounting opening 23 that communicates with a second pipe hole 21. A pipe can be installed into the first pipe hole 11 through the first mounting opening 13 and into the second pipe hole 21 through the second mounting opening 23. In addition, the opening direction of the first mounting opening 13 is opposite to the opening direction of the second mounting opening 23, thereby reducing the occurrence of the first shock-absorbing counterweight 1 and the second shock-absorbing counterweight 2 detaching from the pipe at the same time, and improving the stability of the shock-absorbing device installation.

[0032] Please see Figure 1 and Figure 2The first damping counterweight 1 has a first receiving cavity 14, and the second damping counterweight 2 has a second receiving cavity 24. Both the first receiving cavity 14 and the second receiving cavity 24 are equipped with a wave deflector 3. The wave deflector 3 includes multiple base plates 31 and multiple baffles 32. Each base plate 31 is fixedly connected to the cavity wall of the first receiving cavity 14 or the cavity wall of the second receiving cavity 24. The baffles 32 are fixedly connected to the base plate 31, so that the wave deflector 3, the cavity walls of the first receiving cavity 14 and the cavity walls of the second receiving cavity 24 together form a buffer channel 4, and the buffer channel 4 is filled with damping fluid. In this embodiment, the wave deflector 3 is made of rubber and is integrally formed with the first damping counterweight 1 or the second damping counterweight 2. In this embodiment, the damping fluid is a low-temperature resistant damping fluid, thereby preventing the damping fluid from failing in low-temperature environments.

[0033] When pipeline vibration is transmitted to the damping device, the damping fluid first absorbs the vibration energy. Part of the vibration's mechanical energy is converted into the damping fluid's internal energy, and the remaining mechanical energy is converted into the damping fluid's kinetic energy. This causes the damping fluid to tumble and generate surges within the first receiving cavity 14 or the second receiving cavity 24. These surges impact multiple anti-surge plates 3 within the first receiving cavity 14 or the second receiving cavity 24, causing the anti-surge plates 3 to undergo elastic deformation. The damping fluid's kinetic energy is then converted into the anti-surge plate's internal energy. Furthermore, since the first damping counterweight 1 and the second damping counterweight 2 are entirely made of rubber, their movement exhibits hysteresis. Under high-frequency pipeline vibration, the kinetic energy of the first damping counterweight 1 and the second damping counterweight 2 during movement partially cancels out the pipeline vibration energy, further enhancing the damping capacity of the first damping counterweight 1 and the second damping counterweight 2.

[0034] Please see Figure 1 and Figure 2 The shock-absorbing device also includes a retaining ring. A first storage groove 15 for accommodating the retaining ring is formed on the side wall of the first shock-absorbing counterweight 1, and a second storage groove 25 for accommodating the retaining ring is formed on the side wall of the second shock-absorbing counterweight 2. When the shock-absorbing device is secured to the pipe, the retaining ring is fitted onto the first shock-absorbing counterweight 1 and the second shock-absorbing counterweight 2 and accommodated in the first storage groove 15 and the second storage groove 25, thereby securing the first shock-absorbing counterweight 1 and the second shock-absorbing counterweight 2 tightly. The first storage groove 15 and the second storage groove 25 reduce the occurrence of the retaining ring slipping off the first shock-absorbing counterweight 1 and the second shock-absorbing counterweight 2. In this embodiment, the retaining ring can be a cable tie or a rubber band.

[0035] When it is necessary to fix a vibrating pipe, the first damping counterweight 1 is installed on the pipe, so that the pipe is inserted into the first pipe hole 11 through the first installation opening 13, and the wall of the first pipe hole 11 is tightly abutted against the side wall of the pipe. Then, the second damping counterweight 2 is installed on another pipe, so that the connecting part 12 is placed in the connecting groove 221. Finally, the first damping counterweight 1 and the second damping counterweight 2 are tied and fixed as a whole by a fixing ring, thereby realizing the fixation of the damping device to the vibrating pipe. This application also provides an air conditioner, which includes the damping device described above. Since the air conditioner has the above-mentioned damping device, it has at least some or all of the beneficial effects of the above-mentioned damping device, which will not be described in detail here.

[0036] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0037] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
