Description

Technical Field

[0001] The utility model relates to the field of mufflers, in particular to a compressor muffler. Background Art

[0002] The operating characteristics of the compressor are to complete the suction, compression and exhaust process periodically. In addition to the mechanical friction noise between the parts, the suction and exhaust process will generate vibration and flow noise of compressed gas. These noises may be transmitted to the exhaust pipe and further spread to the room or the surrounding environment, causing unnecessary noise pollution. Therefore, in general, the compressor will add a muffler to reduce noise.

[0003] For example, the patent with authorization announcement number CN217129730U discloses an assembled compressor silencer, including a silencer body, a silencer base is installed at one end of the silencer body, a silencer top cover is installed at the other end of the silencer body, a mounting structure is slidably installed on the outside of the silencer body between the silencer base and the silencer top cover, a cleaning device is installed on the mounting structure, a guide plate is installed at the inner end of the silencer base and the silencer top cover, the guide plate is a ring structure, and the silencer body is fixed together with the silencer base and the silencer top cover by screws.

[0004] The above patent provides a cleaning device and an installation structure, so that the silencer of the compressor can be cleaned without being disassembled, thereby ultimately improving the convenience of cleaning the compressor silencer and also improving the cleaning efficiency of the compressor silencer; however, the disadvantage of the above patent is that the cleaning device will block the air intake structure of the silencer body, reducing the air intake efficiency of the compressor.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0024] See also Figure 1-5 The compressor silencer is similar to the patent in the background technology and also includes a silencer body 1. The innovation of this solution is that:

[0025] The bottom of the muffler body 1 is integrally formed with a lower connecting platform 2, and the top of the muffler body 1 is integrally formed with an upper connecting platform 3, wherein the lower connecting platform 2 and the upper connecting platform 3 are both in the shape of a truncated cone, wherein a lower connecting ring 5 is movably connected to the lower connecting platform 2, and an upper connecting ring 6 is movably connected to the upper connecting platform 3, wherein the major diameter of the upper connecting platform 3 should be smaller than the minor diameter of the lower connecting platform 2, so that the lower connecting ring 5 can pass over the upper connecting platform 3;

[0026] like Figure 5 As shown, the outer periphery of the muffler body 1 is also provided with a filter screen 8 in the form of a round tube with upper and lower openings.

[0027] At the same time Figure 4 As shown, the lower end of the filter screen 8 is stuck between the lower connecting platform 2 and the lower connecting ring 5, and the upper end of the filter screen 8 is stuck between the upper connecting platform 3 and the upper connecting ring 6. The upper and lower ends of the filter screen 8 are squeezed and deformed and stuck between the connecting platform and the connecting ring.

[0028] At the same time, the inclination angle of the outer wall of the upper connecting platform 3 is the same as the inclination angle of the inner wall of the upper connecting ring 6, and the height of the upper connecting ring 6 is smaller than the height of the upper connecting platform 3;

[0029] The inclination angle of the outer wall of the lower connecting platform 2 is the same as the inclination angle of the inner wall of the lower connecting platform 2, and the height of the lower connecting platform 2 is less than the height of the lower connecting platform 2;

[0030] In the embodiment of the present scheme, the lower connecting platform 2 and the upper connecting platform 3 are both in the shape of a truncated cone and are provided with external threads 4 on the surface, and the inner walls of the lower connecting ring 5 and the upper connecting ring 6 are provided with internal threads 7 adapted to the external threads 4; wherein the radial matching clearance of the internal and external threads is at least 0.10 mm;

[0031] In this solution, the filter screen 8 is a non-woven fabric, and the filter screen 8 can also be a flexible filter material in the prior art, such as synthetic fiber; the thickness of the filter screen 8 should be less than 0.05 mm;

[0032] To ensure that after the surface of the external thread 4 is covered with the filter screen 8, there is still a 0.05mm matching gap between the external thread 4 and the internal thread 7 after covering the filter screen 8, so as to avoid the thread from getting stuck and damaged;

[0033] When a lot of dust accumulates on the filter, the lower connecting ring 5 and the upper connecting ring 6 of the present solution can be rotated from the lower connecting platform 2 and the upper connecting platform 3, and then the filter can be pulled from the top of the muffler. At this time, the filter can be replaced or the filter can be cleaned and then installed;

[0034] In this solution, an easily replaceable tubular filter is used. Different from the mode of cleaning the muffler air inlet in the prior art, this solution uses an easily replaceable external filter, which also does not require the muffler to be disassembled for cleaning.

[0035] like Figure 6-7 As some embodiments of the present scheme, the difference from the above embodiments is that the side wall of the filter 8 is folded. Specifically, the side of the filter is arranged in a circular array with multiple folded layers 9. The advantage of this arrangement is that it increases the contact area of ​​the filter and improves the dust filtering effect.

In addition, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In the description of the present utility model, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "connection" and the like should be understood in a broad sense, for example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.
