Description

Technical Field

[0001] This utility model belongs to the field of compressors and relates to a silencer structure, particularly to an air compressor silencer structure. Background Technology

[0002] During operation, the cylinders of an air compressor generate significant noise due to airflow impact and gas vibration. This noise not only affects the working environment but may also damage the hearing of operators.

[0003] To address the aforementioned problems, various improvements have been made to the air compressor cylinder. For example, Chinese patent literature discloses an air compressor with a silencer (application number CN202221118771.7), which includes a left cylinder assembly and a right cylinder assembly arranged opposite each other. Both the left and right cylinder assemblies have an intake chamber and an exhaust chamber. A silencer with a silencer chamber is provided between the left and right cylinder assemblies. The silencer chamber is divided by a filter element to form a silencer air inlet chamber and a silencer air outlet chamber. The silencer is provided with an air inlet silencer duct that connects the silencer air inlet chamber to the outside. The intake chambers of the left and right cylinder assemblies are respectively connected to the silencer air outlet chamber through ventilation ducts. An exhaust support pipe is connected through the silencer. The two ends of the exhaust support pipe are respectively inserted into the exhaust chambers of the left and right cylinder assemblies to realize the connection between the exhaust chambers of the left and right cylinder assemblies.

[0004] The aforementioned air compressor with a muffler is equipped with a muffler and an exhaust manifold, connecting the muffler to the air chamber of the left cylinder assembly and the air chamber of the right cylinder assembly. However, this technical solution still has the following shortcomings: Since the muffler is connected to the left and right cylinder assemblies through the exhaust manifold or intake manifold, its connection support relies solely on the exhaust manifold or intake manifold structure. The load-bearing capacity of this connection is poor. During transportation or other human factors, the muffler is easily subjected to force, which can easily lead to deformation or damage to the exhaust manifold, or even breakage, as well as unstable connection and damage to components. Furthermore, the cost of individual components and replacement costs are relatively high. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an air compressor muffler structure that solves these issues.

[0006] The purpose of this utility model can be achieved through the following technical solution: an air compressor muffler structure, including two cylinder assemblies arranged in opposite structures and a muffler assembly with a muffler cavity, wherein the cylinder assembly has an air cavity inside, characterized in that the muffler assembly is located between the two cylinder assemblies, and an installation step for limiting the installation of the muffler assembly is provided at the upper end of the cylinder assembly.

[0007] The mounting step is provided with a gas guide hole that allows gas to enter or exit and communicates with the inside of the gas chamber.

[0008] The silencing assembly includes a silencer for reducing aerodynamic noise and two connecting parts for connection and fixation. The connecting parts have an auxiliary cavity for secondary silencing and noise reduction and are interconnected with the silencing cavity. The connecting parts are also provided with air holes that cooperate with and communicate with the air holes.

[0009] The two connecting parts are fixedly installed on the mounting step and fastened together by fastening bolts;

[0010] Several connecting ribs are provided between the lower end of the connecting part and the silencer to improve the connection strength. The silencer is also provided with an air connector that facilitates the access and exit of the air source and is connected to the inside of the silencer cavity.

[0011] In the above-mentioned air compressor muffler structure, the cylinder assembly includes a cylinder body and a cylinder head, with the mounting steps and air guide holes located at the upper end of the cylinder head, forming an upper intake and exhaust structure.

[0012] In the above-mentioned air compressor muffler structure, the connecting ribs are distributed at intervals between the connecting part and the muffler connection to improve the compressive strength of the connection. The connecting ribs are arranged in a triangular structure, and the connecting part and the muffler can be integrally formed.

[0013] In the above-mentioned air compressor muffler structure, the auxiliary cavity and the muffler cavity are interconnected, forming a multi-layer muffler structure that reduces the aerodynamic noise of intake and exhaust.

[0014] Compared with existing technologies, the silencer structure of this air compressor has the following advantages:

[0015] 1. Optimized air intake and exhaust structure: By adopting an upper air intake and exhaust method, compared with the traditional side air intake and exhaust, this design optimizes the branch pipe structure, making the gas flow smoother and reducing unnecessary resistance and noise.

[0016] 2. Enhanced structural stability and load-bearing capacity: The connecting ribs are arranged in a triangular structure, and the connection part and the muffler can be integrally formed. This design significantly enhances the stability and load-bearing capacity of the entire muffler structure. The triangular structure can effectively disperse and bear forces and pressures from different directions. When subjected to external forces, it can evenly distribute the force to each side, thereby reducing the concentration of local stress and improving the overall durability.

[0017] 3. Multi-layer silencer structure reduces noise: The auxiliary chamber and the silencer chamber are interconnected, forming a multi-layer silencer structure. This design can effectively reduce the aerodynamic noise of intake and exhaust, improve the silencer's silencing effect, and make the air compressor quieter during operation.

[0018] 4. Easy to install and maintain: The muffler assembly is located between the two cylinder assemblies and is fixed by mounting steps and fastening bolts. This design makes the installation and disassembly of the muffler more convenient and quick, which is beneficial to the daily maintenance and upkeep of the air compressor.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the silencer structure of this air compressor includes two cylinder assemblies arranged in opposite directions and a silencer assembly with a silencer chamber 5. The cylinder assemblies have an internal air chamber. The silencer assembly is located between the two cylinder assemblies. An installation step 2 is provided at the upper end of the cylinder assembly for limiting the installation of the silencer assembly. An air guide hole 3 is provided on the installation step 2 for gas to enter or exit and communicate with the interior of the air chamber. The silencer assembly includes a silencer 10 for reducing aerodynamic noise and two connecting parts 4 for connection and fixation. The connecting parts 4 have an auxiliary chamber 6 for secondary noise reduction and communicate with the silencer chamber 5. An air hole 8 is also provided on the connecting parts 4 and communicates with the air hole 8. The two connecting parts 4 are limited and installed on the installation step 2 and fixed together by fastening bolts. Several connecting ribs 7 are provided between the lower end of the connecting parts 4 and the silencer 10 to improve the connection strength. The silencer 10 is also provided with an air connector 9 for easy access and exit of the air source and communicates with the interior of the silencer chamber 5. The above-mentioned structure optimizes the air intake and exhaust structure: By adopting a top-intake and exhaust method, compared with the traditional side-intake and exhaust, this design optimizes the branch pipe structure, making the gas flow smoother and reducing unnecessary resistance and noise. Enhanced structural stability and load-bearing capacity: The connecting rib 7 is arranged in a triangular structure, and the connecting part 4 and the silencer 10 can be integrally formed. This design significantly enhances the stability and load-bearing capacity of the entire silencer 10 structure. The triangular structure can effectively disperse and bear forces and pressures from different directions. When subjected to external forces, it can evenly distribute the force to each side, thereby reducing the concentration of local stress and improving overall durability. Multi-layer silencing structure reduces noise: The auxiliary chamber 6 and the silencing chamber 5 are interconnected, forming a multi-layer silencing structure. This design can effectively reduce the aerodynamic noise of intake and exhaust, improve the silencing effect of the silencer 10, and make the air compressor quieter during operation. Easy to install and maintain: The muffler assembly is located between the two cylinder assemblies and is fixed by the mounting step 2 and fastening bolts. This design makes the installation and removal of the muffler 10 more convenient and quick, which is beneficial to the daily maintenance and upkeep of the air compressor.

[0026] Prior to this, the cylinder assembly includes a cylinder block and a cylinder head 1, with its mounting step 2 and air guide hole 3 located at the upper end of the cylinder head 1, forming an upper intake and exhaust structure. This differs from the traditional side intake and exhaust, adopting an upper intake and exhaust method to optimize and reduce the branch pipe structure.

[0027] To elaborate further, the connecting ribs 7 are spaced apart between the connecting part 4 and the muffler 10 to improve the compressive strength of the connection. The connecting ribs 7 are arranged in a triangular structure, and the connecting part 4 and the muffler 10 can be integrally formed, enhancing the stability and load-bearing capacity of the structure. The triangular connecting ribs 7 can effectively disperse and bear forces and pressures from different directions. When subjected to external forces, the triangular structure can evenly distribute the force to each side, thereby reducing the concentration of local stress and improving the overall load-bearing capacity.

[0028] Priority is that the auxiliary cavity and the silencing cavity 5 are interconnected, which can form a multi-layer silencing structure, reducing the aerodynamic noise of intake and exhaust.
