The soft connection component 23 blocks the vibration conduction to reduce noise. The limiting copper sleeve 22 and the copper embedment 221 prevent the soft connection component 23 from expanding too much, and the protection component 3 prevents the upper component 21 and the limiting copper sleeve 22 from detaching due to vibration, thereby improving the stability and safety of the equipment, providing users with a quiet environment and extending the life of the equipment.

[0021] Furthermore, the upper end component 21 includes a first welding end 211 welded to one end of the compressor copper tube 1, the other end of the first welding end 211 is connected to a first connecting pipe 212, an upper end plate 213 is provided on the outer wall of the first connecting tube 212, one end of the first connecting tube 212 is sleeved with a first metal head 214, and the upper end plate 213 is connected to multiple protection components 3; the upper end component 21 serves to connect the compressor copper tube 1 and the soft connection component 23, ensuring that the refrigerant can flow smoothly from the compressor copper tube 1 into the soft connection component 23, and at the same time providing a connection point for the protection component 3, thereby enhancing the structural stability of the entire noise reduction mechanism 2.

[0022] Furthermore, the limiting copper sleeve 22 is sleeved on the outside of the first metal head 214, and the top of the limiting copper sleeve 22 is provided with a rubber ring 222 that matches the first metal head 214, and the side wall of the limiting copper sleeve 22 is provided with two symmetrically arranged bolts; the limiting copper sleeve 22 limits the expansion range of the soft connection component 23 to prevent the soft connection component 23 from bursting due to excessive internal pressure, thereby improving the service life and safety of the equipment. The rubber ring 222 can effectively prevent the conduction of sound and vibration, play a role in reducing noise and vibration, thereby reducing noise pollution during the operation of the equipment, reducing the adverse effects of vibration on the internal parts of the equipment and the installation position, and ensuring the stable operation of the equipment.

[0023] Furthermore, the copper embedment 221 can be detachably mounted on the limiting copper sleeve 22, and an arc groove cooperating with the soft connection component 23 is provided on one side of the copper embedment 221, and two bolt holes cooperating with the bolts are provided on the copper embedment 221; the copper embedment 221 cooperates with the limiting copper sleeve 22 to wrap and limit the soft connection component 23, further enhancing the protection of the soft connection component 23, ensuring that when the internal pressure changes, the soft connection component 23 will not be damaged due to excessive expansion, thereby ensuring the safe operation of the equipment.

[0024] Furthermore, the soft connection component 23 includes a silicone layer 231 and a metal fabric layer 232, one end of the silicone layer 231 is connected to the first metal head 214, the other end of the silicone layer 231 is connected to the lower end component 24, and the metal fabric layer 232 is sleeved on the outer wall of the silicone layer 231; the soft connection component 23 blocks the transmission of vibration sound and jitter through the soft connection, reduces noise, and provides a quieter use environment for users. At the same time, the combined design of the silicone layer 231 and the metal fabric layer 232 not only ensures the flexibility of the soft connection, but also improves the durability of the component.

[0025] Furthermore, the lower end component 24 includes a second connecting tube 241 connected to one end of the silicone layer 231, a lower end plate 242 is connected to the outer wall of the second connecting tube 241, the other end of the second connecting tube 241 is connected to a second welding end 243, and one end of the second connecting tube 241 is connected to a second metal head 244; the lower end component 24 cooperates with the soft connection component 23 to realize the circulation of the refrigerant, ensuring that the refrigerant can smoothly flow back from the soft connection component 23 to the compressor copper tube 1, completing the entire refrigeration cycle process.

[0026] Furthermore, the inner side walls of the second welding end 243 and the first welding end 211 are both funnel-shaped; the funnel-shaped configuration of the second welding end 243 and the first welding end 211 facilitates connection and circulation of the refrigerant, reduces resistance of the refrigerant during flow, and improves refrigeration efficiency.

[0027] Furthermore, the tops of the copper insert 221 and the limiting copper sleeve 22 are provided with a plurality of I-shaped grooves, each of which is provided with a metal wedge 223 that matches the metal wedge 223, which is installed with the limiting copper sleeve 22 and the copper insert 221 by screws; when the internal pressure of the metal wedge 223 increases, the limiting copper sleeve 22 and the copper insert 221 are protected from wrapping and limiting the soft connection component 23, thereby improving the safety of the equipment. It is ensured that the soft connection component 23 can be effectively protected under various working conditions to prevent equipment failure caused by pressure changes.

[0028] Furthermore, the protection component 3 includes a metal belt 31, both ends of which are hinged with hinges 32, and the two hinges 32 are respectively connected to one side of the upper end plate 213 and one side of the limiting copper sleeve 22; the protection component 3 exerts tensile traction on the upper end component 21 and the limiting copper sleeve 22 at both ends, which plays a limiting role, avoids the separation of the two due to vibration, and improves the operation stability of the equipment; during the operation of the equipment, the protection component 3 can effectively reduce the loosening of components caused by vibration, extend the service life of the equipment, and ensure the safe and reliable operation of the equipment.

[0029] Working principle: 1. Installation process: First, cut off the center of the compressor copper tube 1, and plug the ports at the cut position into the two ends of the noise reduction mechanism 2 respectively, and connect the compressor copper tube 1 to the noise reduction mechanism 2 by welding. After completion, insert the copper insert 221 into the bayonet of the limit copper sleeve 22, and install the copper insert 221 and the limit copper sleeve 22 by bolts. In order to ensure the stability after installation, place two metal wedges 223 in the corresponding I-shaped groove cavity and install them by screws. Its main function is to ensure the limit when the internal pressure increases. The copper sleeve 22 and the copper insert 221 wrap and limit the soft connection component 23, so as to avoid the problem of the volume expansion and bursting of the soft connection component 23 caused by excessive internal pressure of the soft connection component 23, thereby improving the service life of the equipment and the safety of the equipment. After completion, multiple protection components 3 are connected to the limiting copper sleeve 22 and the upper component 21. When the equipment shakes, the upper component 21 and the limiting copper sleeve 22 at both ends can be stretched by the protection component 3 to limit the position and avoid the separation of the two due to vibration, thereby improving the stability of the equipment operation; 2. Noise reduction principle: The traditional compressor copper tube 1 can conduct vibration losslessly on the compressor copper tube 1 through a direct connection. The conducted vibration sound is loud and the vibration is violent. The soft connection of the soft connection component 23 makes it impossible for the vibration to be smoothly conducted to the lower end component 24 when it is conducted to the soft connection component 23, thereby cutting off the transmission of the vibration sound and vibration. In order to avoid the problem of excessive expansion of the soft connection component 23 causing damage to the material and causing leakage of the refrigerant, the equipment limits the expansion volume of the soft connection component 23 through a limiting copper sleeve 22. Therefore, a rubber ring 222 is provided at the connection between the limiting copper sleeve 22 and the first metal head 214. The rubber material of the rubber ring 222 is in contact, which can effectively avoid the conduction effect of sound and vibration, and play a role in reducing noise and vibration, thereby ensuring that the vibration conduction is blocked when the equipment is running, and avoiding the noise caused by vibration conduction and the loosening of the internal parts of the equipment and the loosening of the installation position caused by vibration conduction. 3. Working process: The compressor transports the refrigerant to the noise reduction mechanism 2 through the compressor copper tube 1. During the process, the temperature of the refrigerant will change. When the temperature rises, the air pressure in the tube will also increase accordingly, which will cause the soft connection component 23 to expand. In order to avoid excessive expansion that causes the material of the soft connection component 23 to be unable to withstand it, it is wrapped by a limiting copper sleeve 22 and a copper embedding block 221 to limit the expansion range of the soft connection component 23 to ensure the safe operation of the equipment.

[0030] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
