[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] like Figure 1As shown, an embodiment of this utility model provides a particle damper, including a damping part 10 and a connecting part 20. The damping part 10 includes a damping box 11 and a sealing member 12. The damping box 11 has a receiving cavity 111 and a filling port 112 communicating with the receiving cavity 111. The receiving cavity 111 is used to hold damping particles. The damping particles are loaded into the receiving cavity 111 from the filling port 112. The sealing member 12 and the damping box 11 are detachably connected, for example, by threaded connection, snap-fit, suction, etc. The sealing member 12 seals the filling port 112. The connecting part 20 is connected to or integrally formed with the damping box 11. The connecting part 20 is used to connect with the structure to be damped.

[0029] In this design, the damping unit 10 is connected to the structure to be damped via the connecting part 20. The damping unit 10 includes a damping box 11 and a sealing member 12. When the particle damper needs filling, damping particles are added through the filling port 112 and stored in the receiving cavity 111. The sealing member 12 is used to seal the filling port 112 to prevent leakage of the damping particles in the receiving cavity 111. The sealing member 12 and the damping box 11 are detachably connected, facilitating the insertion and replacement of damping particles and allowing for the addition and removal of damping particles as needed. This allows the connecting part 20 of the particle damper to be connected to the structure to be damped first, and then the damping particles to be placed in the damping box 11. In other words, the damping particles do not need to be connected to the structure to be damped along with the particle damper. This avoids the problem of the damping device failing due to the high temperature generated during welding when the particle damper is connected to the structure to be damped, causing the damping particles in the receiving cavity 111 to become a single unit.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in some embodiments, the vibration damping box 11 includes a box body 113 and a box cover 114. The box body 113 and the connecting part 20 are connected or integrally formed. The receiving cavity 111 is located inside the box body 113, and the box cover 114 is connected to the box body 113 to close the opening of the receiving cavity 111. The filling port 112 is provided on the box cover 114. The receiving cavity 111 is provided to store vibration damping particles. The box cover 114 is connected to the box body 113 to close the opening of the receiving cavity 111 and prevent the vibration damping particles from leaking. The filling port 112 is provided on the box cover 114 so that the vibration damping particles can be put into the receiving cavity 111 without opening the box cover 114, which can realize the use of vibration damping particles. The box cover 114 and the box body 113 can be connected by welding. After welding is completed, the vibration damping particles are put into the receiving cavity 111, and then the filling port 112 is closed by the sealing part 12. In this way, the vibration damping particles are not affected by welding.

[0031] In some embodiments, the filling port 112 has an internal thread, and the sealing member 12 has an external thread, with the sealing member 12 and the filling port 112 being threadedly connected; or in some embodiments, the sealing member 12 is made of an elastic material, and a portion of the sealing member 12 is inserted into the filling port 112, in which case the sealing member 12 is a rubber stopper. This arrangement, utilizing the characteristics of the threaded connection or the elastic material, facilitates the installation and removal of the sealing member 12, while also ensuring a sealed connection between the sealing member 12 and the filling port 112, preventing the vibration-damping particles from leaking from the filling port 112 during equipment operation, thus enhancing the reliability of the particle damper.

[0032] In some embodiments, the lid 114 is disposed at the top of the housing 113, such as... Figure 1 , Figure 2 and Figure 4 As shown; or located on the side of the housing 113 away from the connecting part 20, such as Figure 3 As shown, the shape of the cover 114 matches the opening of the receiving cavity 111. The cover 114 and the box body 113 are welded together to form a sealed structure, ensuring that the vibration damping particles will not leak from the opening of the box body 113 under any circumstances.

[0033] In some embodiments, the side wall of the connecting portion 20 is provided with a groove 40 and the side wall of the damping box 11 is provided with a rib 30, or the side wall of the connecting portion 20 is provided with a rib 30 and the side wall of the damping box 11 is provided with a groove 40; the rib 30 and the groove 40 are mutually restrictive to limit the relative position of the damping box 11 and the connecting portion 20. Through the restrictive cooperation of the rib 30 and the groove 40, precise positioning between the damping box 11 and the connecting portion 20 is achieved. When installing the particle damper, it is ensured that the rib 30 and the groove 40 are accurately aligned and fixed to achieve the best connection effect. Furthermore, after achieving precise positioning between the damping box 11 and the connecting portion 20 through the restrictive cooperation of the rib 30 and the groove 40, the damping box 11 and the connecting portion 20 can be fixed by welding.

[0034] like Figure 1 As shown, both sides of the vibration damping box 11 are provided with protruding ribs 30, and the protruding rib 30 on either side engages with the groove 40 of the connecting part 20; or, both sides of the vibration damping box 11 are provided with grooves 40, and the groove 40 on either side engages with the protruding rib 30 of the connecting part 20. The protruding ribs 30 and grooves 40 are provided to limit the relative position of the connecting part 20 and the vibration damping box 11, preventing relative displacement when the connecting part 20 and the vibration damping box 11 are brazed and fixed.

[0035] like Figure 1As shown, in some embodiments, the connecting part 20 and the vibration damping box 11 are separate structures, and the connecting part 20 and the vibration damping box 11 are welded together. Setting the connecting part 20 and the vibration damping box 11 as separate structures can prevent the vibration damping particles in the vibration damping box 11 from deteriorating due to high temperatures or other conditions in the structure to be fastened, thus affecting its vibration damping effect. Or as... Figure 2 , Figure 3 , Figure 4 As shown, the connecting part 20 and the vibration damping box 11 are an integral structure. By making the connecting part 20 and the vibration damping box 11 an integral structure, the vibration damping particles in the vibration damping box 11 can cover a larger area of ​​the structure to be fastened, thereby improving the vibration damping effect.

[0036] like Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments, the connecting portion 20 is welded to the structure to be vibration-damped. Or, as... Figure 4 As shown, the particle damper also includes a fastening structure 50, which detachably connects the connecting part 20 to the structure to be damped. By using welding or a fastening structure, a stable connection between the particle damper and the structure to be damped is achieved. Furthermore, by setting the fastening structure 50 to detachably connect the connecting part 20 to the structure to be damped, the flexibility of installation and disassembly of the particle damper is improved, facilitating connection with different structures to be damped and enhancing the versatility of the particle damper. At the same time, it avoids the change in the properties of the damping particles caused by welding the connecting part 20 to the structure to be damped, which would lead to a loss of damping effect. This design ensures both connection strength and facilitates equipment maintenance.

[0037] like Figure 4 and Figure 5 As shown, the connecting part 20 is a cylindrical structure, and it is sleeved onto the structure to be damped. The fastening structure 50 includes a fastening bolt 51. The side wall of the connecting part 20 has a through threaded hole 21, and the fastening bolt 51 is threadedly connected to the threaded hole 21. One end of the fastening bolt 51 is used to mate with the structure to be damped. By using the connection between the connecting part 20 and the structure to be damped, and the fixing effect of the fastening bolt 51, a tight connection between the particle damper and the equipment is ensured, improving the connection stability and vibration damping effect, while also facilitating assembly and disassembly.

[0038] In this embodiment, there are multiple fastening bolts 51, and the connecting part 20 includes a sleeve 22 and multiple reinforcing nuts 23. The sleeve 22 is connected to the vibration damping part 10, and the multiple reinforcing nuts 23 are fixed to the outer wall of the sleeve 22 along the circumference. Each threaded hole 21 penetrates the side wall of the sleeve 22 and a reinforcing nut 23, and each fastening bolt 51 is connected to a reinforcing nut 23. By increasing the number of fastening bolts 51 and reinforcing nuts 23, the connection strength and stability between the connecting part 20 and the vibration damping part 10 are improved. Even under heavy loads or severe vibrations, a good connection between the particle damper and the equipment can be ensured, achieving effective vibration reduction.

[0039] In some embodiments not shown, the vibration damping box 11 includes a box body 113, which is connected to or integrally formed with the connecting part 20. A receiving cavity 111 is located within the box body 113, and the opening of the receiving cavity 111 forms a filling port 112. The sealing element 12 is a box cover 114, which is detachably connected to the box body 113. The direct connection between the box body 113 and the connecting part 20 simplifies the structure of the particle damper while maintaining the detachable connection between the filling port 112 and the sealing element 12, facilitating the filling and replacement of vibration damping particles.

[0040] In some embodiments, the sealing element 12 and the housing 113 are snap-fitted or threaded together; the vibration damping box 11 also includes a seal disposed between the housing 113 and the sealing element 12. The snap-fit ​​or threaded connection, combined with the use of the seal, ensures the airtightness of the housing 113, prevents leakage of vibration damping particles, improves the reliability of the particle damper, and avoids the impact of particle leakage on equipment performance.

[0041] This utility model also provides an air conditioner, which includes an air conditioning pipe and the aforementioned particulate damper. The air conditioning pipe is connected to the particulate damper via a connection part 20. The vibration damping part 10 is connected to the air conditioning pipe through the connection part 20. The vibration damping part 10 includes a vibration damping box 11 and a sealing member 12. When the particulate damper needs filling, vibration damping particles are added through the filling port 112. The sealing member 12 and the vibration damping box 11 are detachably connected, facilitating the insertion and replacement of vibration damping particles, and allowing for immediate placement and removal of the particles as needed. That is, the vibration damping particles do not need to be connected to the air conditioning pipe along with the particulate damper. This avoids the problem of vibration damping failure caused by the high temperature generated during welding when the particulate damper is connected to the air conditioning pipe, which can cause the vibration damping particles to become a single unit.
