Technical Field
[0001] This utility model relates to the field of compressor parts technology, and in particular to a compressor muffler cover that is easy to disassemble and assemble. Background Technology
[0002] A compressor muffler cover is a noise reduction device installed on the outside of a compressor (usually covering the compressor's core working components, such as the motor and cylinders). It is primarily made of metal, high-strength plastic, or composite materials (such as modified polypropylene) for the outer shell, with internal sound-absorbing, sound-insulating, and damping materials. While not a core functional component of the compressor, it significantly reduces compressor noise during operation through structural design and material properties, making it a key component of the compressor noise reduction system.
[0003] Currently available compressor mufflers typically rely on a sound-absorbing filling layer fixed inside the end cover for sound absorption, achieving a good noise reduction effect. However, to ensure compressor heat dissipation, heat dissipation vents need to be reserved on the muffler cover, which easily allows external dust to enter the compressor through the vents. This makes it inconvenient to clean the dust adhering to the surface of the sound-absorbing filling layer, significantly increasing the convenience of muffler cover maintenance. Therefore, this application proposes a compressor muffler cover that can effectively block dust and is easy to clean and maintain, and is easy to disassemble and install. Utility Model Content
[0004] The purpose of this invention is to address the problem in the prior art that external dust can easily enter the compressor through the heat dissipation vents, and it is difficult to clean the dust adhering to the surface of the sound-absorbing filling layer inside the sound-absorbing cover. The invention proposes a compressor sound-absorbing cover that can effectively block dust and is easy to clean and maintain.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0030] Example
[0031] like Figures 1-5 As shown, this utility model proposes a compressor muffler cover that is easy to assemble and disassemble, including a shell 1. One end of the shell 1 has several arc-shaped heat dissipation vents 7. Inside the shell 1, several arc-shaped dust covers 2 are installed in a ring-like arrangement at equal intervals. At least three sets of arc-shaped dust covers 2 are provided, with several arc-shaped dust covers 2 arranged in the same set forming a circular structure. These multiple circular structures are distributed inside the shell 1 in a nested manner. Both ends of the aforementioned arc-shaped dust covers 2, which are far apart, have heat dissipation holes 21. Heat inside the compressor can be discharged outwards through the heat dissipation holes 21, ensuring the compressor's heat dissipation effect. External dust enters the arc-shaped dust cover 2 after passing through the arc-shaped heat dissipation vent 7, effectively intercepting external dust and preventing it from entering the compressor and adhering to the surface of the sound-absorbing filler layer. A shock-absorbing component 3 is fixedly installed at the bottom of the outer shell 1. Several pressure plates 35 are mounted on the shock-absorbing component 3. These pressure plates 35 press against the top of the matching semi-arc-shaped dust cover 2, ensuring that the arc-shaped dust cover 2 can be firmly installed inside the outer shell 1. The arc-shaped dust cover 2 can be disassembled by removing the pressure plates 35, making it convenient to clean the dust inside and effectively improving the convenience of maintaining the sound-absorbing cover.
[0032] like Figure 3 and Figure 4 As shown, in order to improve the dust interception effect of the arc-shaped dust cover 2, a filling cavity 22 is provided inside the arc-shaped dust cover 2. The sponge block is filled in the filling cavity 22. Since the sponge block is a porous material, the heat inside the compressor can pass through the pores on the sponge block and be discharged to the outside, so it will not affect the heat dissipation of the compressor. After the external dust enters the filling cavity 22, it can be absorbed and intercepted by the porous structure of the sponge block, which effectively improves the dust interception effect of the arc-shaped dust cover 2. When it is necessary to clean the dust inside the arc-shaped dust cover 2, the sponge block can be removed, which is convenient to operate.
[0033] Furthermore, in order to improve the stability of the arc-shaped dust cover 2 after installation, a docking frame 23 is fixedly installed at the open end of the arc-shaped dust cover 2. When the arc-shaped dust cover 2 is installed inside the outer shell 1, the docking frame 23 is inserted into the matching arc-shaped heat dissipation port 7 and tightly engaged with it, thus preventing the arc-shaped dust cover 2 from shaking and rotating, effectively improving its stability after installation.
[0034] like Figure 1 and Figure 3 As shown, in order to improve the noise reduction performance of the silencing cover, annular silencing plates 8 are fixedly installed on the outer walls of several arc-shaped dust covers 2 arranged in the same group. The adjacent annular silencing plates 8 are staggered. Through multiple sets of staggered annular silencing plates 8, a multi-layer plate structure can be formed in the area between two adjacent arc-shaped dust covers 2, increasing the noise transmission path. In the process of frequent contact between noise and the multi-layer plate structure, the noise reduction effect is effectively achieved.
[0035] Furthermore, a damping cylinder 5 and a sound-absorbing cylinder 6 are inserted inside the outer casing 1. The sound-absorbing cylinder 6 is installed between the outer wall of the damping cylinder 5 and the inner wall of the outer casing 1. The damping cylinder 5 can be made of butyl rubber material and covers the inner side of the outer casing 1 or the surface in contact with the compressor to absorb vibration energy and reduce secondary noise. The sound-absorbing cylinder 6 can be made of polyester fiber cotton material and is attached to the inner side of the outer casing 1. Through its porous structure, it absorbs aerodynamic noise and enhances the sound absorption effect of the silencer cover.
[0036] Secondly, in order to facilitate the installation of the damping cylinder 5 and the sound-absorbing cylinder 6, several positioning rods 4 are fixedly installed on the inner bottom of the outer shell 1. When the positioning rods 4 pass through the holes drilled in the damping cylinder 5 and the sound-absorbing cylinder 6, the damping cylinder 5 and the sound-absorbing cylinder 6 can be positioned to prevent them from rotating. This not only facilitates the installation, but also improves the firmness of the installation.
[0037] like Figure 1 and Figure 5 As shown, in order to provide the vibration reduction effect of the muffler cover, the support cylinder 31, which constitutes the vibration reduction component 3, is fixedly installed at the bottom of the outer shell 1. Several rubber blocks 32 are embedded and engaged inside the support cylinder 31. Two adjacent rubber blocks 32 are engaged and connected. The contact plate 34 installed at the open end of the support cylinder 31 is engaged and connected with the matching rubber block 32. When the muffler cover is installed on the compressor, the contact plate 34 is in close contact with the motor end cover inside the compressor. During the operation of the motor, the multiple rubber blocks 32 can buffer the vibration generated by it, effectively providing the vibration reduction effect of the muffler cover.
[0038] Furthermore, to facilitate the disassembly of the arc-shaped dust cover 2, a sleeve 33 is tightly fitted onto the outer wall of the support cylinder 31. Several pressure plates 35 are fixedly installed on the outer wall of the sleeve 33. After removing the sleeve 33, the top of the arc-shaped dust cover 2 loses the pressure and positioning of the pressure plates 35, making it easy to pull the arc-shaped dust cover 2 out from the arc-shaped heat dissipation port 7 and facilitate its disassembly.
[0039] In this embodiment, the damping cylinder 5 installed inside the outer shell 1 first absorbs vibration energy and reduces secondary noise. The porous structure inside the sound-absorbing cylinder 6 absorbs aerodynamic noise. Combined with the annular sound-absorbing plate 8 installed on the outer wall of the arc-shaped dust cover 2, noise reduction is effectively achieved, ensuring the sound-absorbing performance of the sound-absorbing cover. When the sound-absorbing cover is installed on the compressor, the heat inside the compressor enters the stuffing cavity 22 through the heat dissipation hole 21 and is then discharged outward from the arc-shaped heat dissipation port 7, ensuring the heat dissipation effect of the compressor. Since the stuffing cavity 22 is filled with sponge blocks, when external dust enters the stuffing cavity 22, it absorbs the vibration energy and reduces secondary noise. The sponge block can absorb and intercept the dust, preventing it from entering the compressor and avoiding dust adhering to the surface of the sound-absorbing material inside the muffler cover, thus increasing the difficulty of cleaning. When it is necessary to clean the dust inside the arc-shaped dust cover 2, remove the outer shell 1 of the muffler cover and then remove the sleeve 33 from the support cylinder 31. Ensure that the arc-shaped dust cover 2 is no longer pressed and positioned by the pressure plate 35, and the arc-shaped dust cover 2 can be removed from the outer shell 1. At this time, the opening end of the arc-shaped dust cover 2 is unobstructed, making it easy to remove the sponge block that has absorbed the dust and to clean the intercepted dust, effectively improving the convenience of muffler cover maintenance.
[0040] The above specific embodiments are merely several optional embodiments of this utility model.
