Technical Field

[0001] This utility model relates to the field of silencer technology, and in particular to a miniature silent silencer. Background Technology

[0002] Pipeline end silencers are noise reduction devices installed at the end of pipelines. They absorb sound energy through internal sound-absorbing materials, thereby reducing the noise generated by fluid flow in the pipeline. This can effectively reduce noise pollution to the surrounding environment and improve the comfort of the working and living environment.

[0003] However, existing silencers have shortcomings. First, existing silencers only absorb noise by lining the interior with sound-absorbing material, resulting in poor noise reduction and failing to meet noise reduction requirements. Second, existing silencers lack a quick-release mechanism between the silencer and the pipe end, making it inconvenient to remove the silencer for cleaning and maintenance. Therefore, a miniature silent silencer is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a miniature silent silencer, which aims to improve the existing silencers that only absorb noise by setting a sound-absorbing material lining inside, resulting in poor noise reduction effect and failure to meet noise reduction requirements. It also addresses the problem that the existing silencers lack a quick disassembly and assembly structure between the silencer and the pipe end, making it inconvenient to remove the silencer for cleaning and maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a miniature silent silencer, comprising a cylinder and a tube, wherein an annular steel mesh is fixedly connected to the inner wall of the cylinder, and a sound-absorbing layer is filled between the cylinder and the annular steel mesh; a flow guiding component is installed on the inner wall of the annular steel mesh; an insertion head is fixedly connected to one end of the cylinder; a connecting ring is inserted into the inner wall of the insertion head, and the connecting ring is fixedly sleeved on one end of the tube; connecting seats are fixedly connected to both sides of the insertion head, and a limit component is installed on the inner wall of the connecting seat;

[0006] The flow guiding component includes several upper baffles, several lower baffles, and several sound-absorbing pads. Several upper baffles are uniformly and fixedly connected to the top of the inner wall of the annular steel mesh, and several lower baffles are uniformly and fixedly connected to the bottom of the inner wall of the annular steel mesh. Sound-absorbing pads are fixedly connected to one side of each upper baffle and one side of each lower baffle.

[0007] As a further description of the above technical solution:

The annular steel mesh 3 is used to support the sound-absorbing layer 2, and its mesh allows sound energy to pass through and be absorbed by the sound-absorbing layer 2. A flow guiding component is installed on the inner wall of the annular steel mesh 3 to guide airflow and weaken sound energy. An insertion head 9 is fixedly connected to one end of the cylindrical body 1. A connecting ring 11 is inserted into the inner wall of the insertion head 9, and the connecting ring 11 is fixedly sleeved on one end of the tube body 10.

[0032] Reference Figure 3The flow guiding component includes several upper baffles 7, several lower baffles 6, and several sound-absorbing pads 8. Several upper baffles 7 are uniformly fixed to the top of the inner wall of the annular steel mesh 3, and several lower baffles 6 are uniformly fixed to the bottom of the inner wall of the annular steel mesh 3, so that sound waves are reflected and refracted multiple times in it, consuming energy and achieving the effect of blocking noise. Sound-absorbing pads 8 are fixedly connected to one side of the upper baffles 7 and one side of the lower baffles 6, which can further absorb sound wave energy and improve the noise reduction effect.

[0033] Reference Figure 4 Limiting grooves 12 are provided on both sides of the connecting ring 11. The limiting component includes a through rod 14, a limiting block 15 and a spring 17. The through rod 14 is inserted and connected to the middle of one side of the connecting seat 13. One end of the through rod 14 is fixedly connected to the limiting block 15.

[0039] Reference Figure 1 A filter screen 5 is fixedly connected to the inner wall of the end cap 4 to prevent dust and impurities in the air from entering the silencer and to avoid clogging the mesh of the annular steel mesh 3, which would affect the noise reduction effect.

[0040] Working principle: Both the sound-absorbing layer 2 and the sound-absorbing pad 8 are made of sound-absorbing cotton. An annular steel mesh 3 and the sound-absorbing layer 2 are set on the inner wall of the silencer. Sound energy will pass through the mesh and be absorbed by the sound-absorbing layer 2, reducing noise. There are also staggered upper baffles 7 and lower baffles 6 in the annular steel mesh 3. The sound waves consume energy through multiple reflections and refractions, blocking noise. The side walls of the baffles have sound-absorbing pads 8, which can further improve the quietness effect and meet people's noise reduction needs. The insertion head 9 of the silencer is inserted into the connecting ring 11 at the end of the tube body 10. Under the action of the spring 17, the limiting block 15 can be inserted into the limiting groove 12 on the side wall of the connecting ring 11 to fix the position of the silencer. By pulling the pull rings 16 on both sides of the insertion head 9 at the same time, the limiting block 15 can be disengaged from the limiting groove 12 by the through rod 14, and the limiting can be released to remove the silencer body. It is convenient and quick to clean and maintain the silencer body.
