Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology, and in particular to an easily detachable noise reduction component and a silencer. Background Technology

[0002] The use of microporous plates in silencers can significantly improve noise reduction. However, since silencers are often used in pipes, they come into contact with a lot of dust, which can easily clog the microporous plates, thus affecting the noise reduction effect. For example, the invention patent application with application number CN202311150155.9 allows the first and second connecting parts to make the first panel detachable. However, it is either a hinge or a detachable snap-fit. The hinge method cannot completely remove the first panel from the silencer, resulting in poor cleaning convenience. While the detachable snap-fit ​​method can completely remove the first panel from the silencer, the snap-fit ​​will cause poor stability of the first panel at the time of snap-fit, thus affecting the noise reduction of the silencer. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an easy-to-disassemble silencer component and silencer that can improve cleaning convenience while ensuring installation stability.

[0008] When the microporous sound-absorbing plate is housed within the mounting frame, and the two elastic abutment members protrude relative to each other from the two walls of the microporous sound-absorbing plate, the side of the microporous sound-absorbing plate away from each elastic abutment member and the side of each elastic abutment member away from the microporous sound-absorbing plate abut against the two walls of the corresponding abutment groove, and each elastic abutment member abuts against the bottom of the corresponding abutment groove.

[0009] In one embodiment, the number of elastic abutment members corresponding to any of the abutment grooves is two or more, and the two or more elastic abutment members are arranged along the extension direction of the abutment groove.

[0010] In one embodiment, when the microporous silencing plate is housed within a mounting frame and the two elastic abutment portions protrude relative to each other from the two sides of the microporous silencing plate, the microporous silencing plate is spaced apart from the bottom of each abutment groove near the periphery of each abutment groove.

[0011] In one embodiment, the resilient abutment is a spring sheet.

[0012] In one embodiment, the elastic abutment is rotatably connected to the microporous sound-absorbing plate via a rotating shaft.

[0013] In one embodiment, each of the elastic abutment members includes a first lever arm, a bending portion, and a second lever arm.

The first lever arm is rotatably connected to the microporous sound-absorbing plate, and the rotation axis of the first lever arm is the same as the thickness direction of the microporous sound-absorbing plate.

[0014] The bent portions of the two elastic abutment members protrude from the two circumferential walls of the microporous sound-absorbing plate, and can be recessed into the circumferential wall of the microporous sound-absorbing plate when the corresponding first lever arm rotates relative to the microporous sound-absorbing plate. The bent portion of each elastic abutment member is configured to elastically deform along the thickness direction of the microporous sound-absorbing plate so that the second lever arm moves toward the direction closer to the first lever arm.

[0015] When the microporous sound-absorbing plate is housed within the mounting frame, and the bent portions of the two elastic abutment members protrude relative to each other from the two walls of the microporous sound-absorbing plate, the side of the microporous sound-absorbing plate away from each of the first lever arms and the side of the second lever arm of each elastic abutment member away from the microporous sound-absorbing plate abut against the two walls of the corresponding abutment groove, and the bent portion of each elastic abutment member abuts against the bottom of the corresponding abutment groove.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] This utility model's easily detachable and assembleable sound-absorbing component allows the microporous sound-absorbing plate to be detachably housed within a mounting frame. Two elastic abutment members, at least partially protruding from both sides of the microporous sound-absorbing plate's periphery, can retract into the periphery of the plate when rotating relative to it. Specifically, when the elastic abutment members rotate relative to the microporous sound-absorbing plate, a portion of the elastic abutment member can extend beyond the outer side of the periphery and retract to the inner side. This facilitates the pushing of the microporous sound-absorbing plate into the mounting frame when the connecting member retracts to the inner side of the periphery. After the microporous sound-absorbing plate is pushed into the mounting frame, applying external force causes the elastic abutment members to rotate relative to the microporous sound-absorbing plate, thus accommodating the microporous sound-absorbing plate within the mounting frame. When the two elastic abutment parts protrude relative to each other from the two sides of the microporous sound-absorbing plate, the side of the microporous sound-absorbing plate away from each elastic abutment part and the side of each elastic abutment part away from the microporous sound-absorbing plate abut against the two groove walls of the corresponding abutment groove, and each elastic abutment part abuts against the bottom of the corresponding abutment groove, so that the part of the elastic abutment part protruding from the side wall of the microporous sound-absorbing plate extends into the abutment groove. With each elastic abutment part configured to elastically expand and contract along the thickness direction of the microporous sound-absorbing plate, the sound-absorbing plate and the elastic abutment parts are elastically engaged in the abutment groove together, which better ensures the installation stability of the microporous sound-absorbing plate in the installation, and the installation operation is simple, effectively improving the cleaning convenience of the microporous sound-absorbing plate.

[0031] This application provides an easily detachable and assembleable sound-absorbing assembly. The aforementioned easily detachable and assembleable sound-absorbing assembly includes at least one microporous sound-absorbing plate, a mounting frame, and at least two elastic abutment members. The microporous sound-absorbing plate is detachably housed within the mounting frame. Both elastic abutment members are rotatably connected to one side of the microporous sound-absorbing plate, and the rotation axis of each elastic abutment member is the same as the thickness direction of the microporous sound-absorbing plate. The mounting frame is provided with two abutment grooves, and the two elastic abutment members are correspondingly arranged with the two abutment grooves. At least partially, the two elastic abutment members protrude relative to the two peripheral walls of the microporous sound-absorbing plate, and when rotated relative to the microporous sound-absorbing plate, they can be recessed into the peripheral wall of the microporous sound-absorbing plate.

This facilitates the pushing of the microporous sound-absorbing plate into the mounting frame when the connector retracts into the inner side of the periphery. After the microporous sound-absorbing plate is pushed into the mounting frame, applying external force causes the elastic abutment members to rotate relative to the plate. Thus, when the microporous sound-absorbing plate is housed within the mounting frame, and the two... When the elastic abutment protrudes from both sides of the microporous sound-absorbing plate, the side of the microporous sound-absorbing plate away from each elastic abutment and the side of each elastic abutment away from the microporous sound-absorbing plate abut against the two groove walls of the corresponding abutment groove, and each elastic abutment abuts against the bottom of the corresponding abutment groove, so that the part of the elastic abutment protruding from the side wall of the microporous sound-absorbing plate extends into the abutment groove.

[0033] To better understand the easily detachable noise reduction component of this application, the following further explanation is provided:

[0034] Please refer to the following: Figures 1 to 5One embodiment of the easily detachable sound-absorbing assembly 10 includes at least one microporous sound-absorbing plate 100, a mounting frame 200, and at least two elastic abutment members 300. The microporous sound-absorbing plate 100 is detachably housed within the mounting frame 200. Both elastic abutment members 300 are rotatably connected to one side surface of the microporous sound-absorbing plate 100, with the rotation axis of each elastic abutment member 300 aligned with the thickness direction of the microporous sound-absorbing plate 100. The mounting frame 200 has two abutment grooves 201, with each elastic abutment member 300 corresponding to one of the two abutment grooves 201. At least partially, each elastic abutment member 300 protrudes from both sides of the microporous sound-absorbing plate 100 and can be recessed into the periphery of the microporous sound-absorbing plate 100 when rotated relative to it. Each elastic abutment member 300 is configured to elastically expand and contract along the thickness direction of the microporous sound-absorbing plate 100. When the microporous sound-absorbing plate 100 is housed within the mounting frame 200, and the two elastic abutment members 300 protrude relative to each other from the two walls of the microporous sound-absorbing plate 100, the side of the microporous sound-absorbing plate 100 away from each elastic abutment member 300 and the side of each elastic abutment member 300 away from the microporous sound-absorbing plate 100 abut against the two walls of the corresponding abutment groove 201, and each elastic abutment member 300 abuts against the bottom of the corresponding abutment groove 201.

[0035] The aforementioned easily detachable sound-absorbing component 10 allows the microporous sound-absorbing plate 100 to be detachably housed within the mounting frame 200. Two elastic abutment members 300, at least partially protruding from both sides of the microporous sound-absorbing plate 100, can be recessed into the periphery of the microporous sound-absorbing plate 100 when rotating relative to it. That is, when the elastic abutment members 300 rotate relative to the microporous sound-absorbing plate 100, a portion of the elastic abutment member 300 can protrude from the microporous sound-absorbing plate 100. The outer side of the peripheral wall of the sound plate 100 and the inner side of the retractable peripheral wall of the microporous sound-absorbing plate 100 facilitate the pushing of the microporous sound-absorbing plate 100 into the mounting frame 200 when the connector retracts into the inner side of the peripheral wall of the microporous sound-absorbing plate 100. After the microporous sound-absorbing plate 100 is pushed into the mounting frame 200, an external force is applied to cause the elastic abutment 300 to rotate relative to the microporous sound-absorbing plate 100, that is, the microporous sound-absorbing plate 100 is housed in the mounting frame 200. When the two elastic abutment members 300 protrude from the two walls of the microporous sound-absorbing plate 100, the side of the microporous sound-absorbing plate 100 away from each elastic abutment member 300 and the side of each elastic abutment member 300 away from the microporous sound-absorbing plate 100 abut against the two walls of the corresponding abutment groove 201, and each elastic abutment member 300 abuts against the bottom of the corresponding abutment groove 201, so that the part of the elastic abutment member 300 protruding from the side wall of the microporous sound-absorbing plate 100 extends into the abutment groove 201. With each elastic abutment member 300 configured to elastically expand and contract along the thickness direction of the microporous sound-absorbing plate 100, the sound-absorbing plate and the elastic abutment member 300 are elastically engaged in the abutment groove 201 together, which better ensures the installation stability of the microporous sound-absorbing plate 100 in the installation, and the installation operation is simple, effectively improving the cleaning convenience of the microporous sound-absorbing plate 100.

[0036] Please refer to the following: Figures 1 to 5 In one embodiment, the number of elastic abutment members 300 corresponding to any abutment groove 201 is two or more, and the two or more elastic abutment members 300 are arranged along the extension direction of the abutment groove 201, which further improves the installation stability of the microporous sound-absorbing plate 100 on the mounting frame 200.

[0037] Please refer to the following: Figures 1 to 5 In one embodiment, when the microporous sound-absorbing plate 100 is housed within the mounting frame 200 and the two elastic abutment members 300 protrude relative to each other from the two sides of the microporous sound-absorbing plate 100, the microporous sound-absorbing plate 100 is spaced apart from the periphery of each abutment groove 201 and the bottom of the abutment groove 201. This ensures that the sidewall of the microporous sound-absorbing plate 100 does not directly abut against the bottom of the abutment groove 201, but rather abuts against the abutment groove 201 through the elastic abutment members 300. This facilitates the removal of the microporous sound-absorbing plate 100 from the mounting frame 200.

[0038] In one embodiment, the elastic abutment is a spring sheet, which ensures the snap-fit ​​strength of the microporous sound-absorbing plate in the abutment groove through the elastic abutment.

[0039] In one embodiment, the elastic abutment is rotatably connected to the microporous silencing plate via a rotating shaft, which effectively ensures the stable rotation of the elastic abutment on the microporous silencing plate.

[0040] Please refer to the following: Figures 1 to 5 In one embodiment, each elastic abutment 300 includes a first lever arm 310, a bent portion 320, and a second lever arm 330. The first lever arm 310 and the second lever arm 330 are respectively connected to the two ends of the bent portion 320. The first lever arm 310 is rotatably connected to the microporous sound-absorbing plate 100, and the rotation axis of the first lever arm 310 is in the same direction as the thickness of the microporous sound-absorbing plate 100. Further, the bent portions 320 of the two elastic abutment members 300 protrude from the two peripheral walls of the microporous sound-absorbing plate 100, and can be recessed into the peripheral wall of the microporous sound-absorbing plate 100 when the corresponding first lever arm 310 rotates relative to the microporous sound-absorbing plate 100. The bent portion 320 of each elastic abutment member 300 is configured to elastically deform along the thickness direction of the microporous sound-absorbing plate 100, so that the second lever arm 330 moves toward the first lever arm 310. Furthermore, when the microporous sound-absorbing plate 100 is housed within the mounting frame 200, and the bent portions 320 of the two elastic abutment members 300 protrude relative to each other from the two walls of the microporous sound-absorbing plate 100, the side of the microporous sound-absorbing plate 100 away from each first lever arm 310 and the side of the second lever arm 330 of each elastic abutment member 300 away from the microporous sound-absorbing plate 100 abut against the two walls of the corresponding abutment groove 201, and the bent portion 320 of each elastic abutment member 300 abuts against the bottom of the corresponding abutment groove 201. This facilitates the elastic abutment member 300 extending smoothly into the abutment groove 201 and stably abutting against the bottom of the abutment groove 201, and better ensures the snap-fit ​​strength of the microporous sound-absorbing plate 100 in the abutment groove 201 through the elastic abutment member 300.

[0041] Please refer to the following: Figures 1 to 5 In one embodiment, the first lever arm 310, the bending portion 320 and the second lever arm 330 of each elastic abutment 300 are integrally formed, which improves the structural strength and compactness of the elastic abutment 300 and reduces the processing steps of the elastic abutment 300, thereby improving the processing and preparation efficiency of the easily disassembled and assembled sound-absorbing component 10.

[0042] Please refer to the following: Figures 1 to 5In one embodiment, a hand 400 is connected to the side of the second lever arm 330 of each elastic abutment 300 away from the microporous sound-absorbing plate 100. Each hand 400 is positioned to avoid the corresponding abutment groove 201, which is beneficial for the user to apply force to rotate and adjust the elastic abutment 300.

[0043] In one embodiment, the microporous sound-absorbing plate has multiple micropores, each micropore extending in the same direction as the thickness of the microporous sound-absorbing plate, and each micropore is positioned to avoid contact with the elastic abutment, thus ensuring the sound absorption and noise reduction effect of the microporous sound-absorbing plate.

[0044] This application also provides a muffler, including the easily detachable muffler assembly of any of the above embodiments. Further, please refer to... Figures 1 to 5 In this embodiment, the easily detachable sound-absorbing assembly 10 includes at least one microporous sound-absorbing plate 100, a mounting frame 200, and at least two elastic abutment members 300. The microporous sound-absorbing plate 100 is detachably housed within the mounting frame 200. Both elastic abutment members 300 are rotatably connected to one side of the microporous sound-absorbing plate 100, and the rotation axis of each elastic abutment member 300 is parallel to the thickness direction of the microporous sound-absorbing plate 100. The mounting frame 200 has two abutment grooves 201, and the two elastic abutment members 300 are correspondingly arranged with the two abutment grooves 201. At least partially, the two elastic abutment members 300 protrude from both sides of the microporous sound-absorbing plate 100, and when rotated relative to the microporous sound-absorbing plate 100, they can be recessed into the periphery of the microporous sound-absorbing plate 100. Each elastic abutment member 300 is configured to elastically expand and contract along the thickness direction of the microporous sound-absorbing plate 100. When the microporous sound-absorbing plate 100 is housed within the mounting frame 200, and the two elastic abutment members 300 protrude relative to each other from the two walls of the microporous sound-absorbing plate 100, the side of the microporous sound-absorbing plate 100 away from each elastic abutment member 300 and the side of each elastic abutment member 300 away from the microporous sound-absorbing plate 100 abut against the two walls of the corresponding abutment groove 201, and each elastic abutment member 300 abuts against the bottom of the corresponding abutment groove 201.

[0045] Compared with the prior art, the present invention has at least the following advantages:

[0046] The easily detachable and assembleable sound-absorbing component 10 of this utility model allows the microporous sound-absorbing plate 100 to be detachably housed within the mounting frame 200. Two elastic abutment members 300, at least partially protruding from the two circumferential walls of the microporous sound-absorbing plate 100, can be recessed into the circumferential walls of the microporous sound-absorbing plate 100 when rotating relative to it. That is, when the elastic abutment members 300 rotate relative to the microporous sound-absorbing plate 100, a portion of the elastic abutment member 300 can extend outwards. The outer side of the peripheral wall of the microporous sound-absorbing plate 100 is retractable to the inner side of the peripheral wall of the microporous sound-absorbing plate 100. This facilitates the pushing of the microporous sound-absorbing plate 100 into the mounting frame 200 when the connector retracts to the inner side of the peripheral wall of the microporous sound-absorbing plate 100. After the microporous sound-absorbing plate 100 is pushed into the mounting frame 200, an external force is applied to cause the elastic abutment 300 to rotate relative to the microporous sound-absorbing plate 100. That is, when the microporous sound-absorbing plate 100 is housed in the mounting frame 200... When the two elastic abutment members 300 protrude from the two walls of the microporous sound-absorbing plate 100, the side of the microporous sound-absorbing plate 100 away from each elastic abutment member 300 and the side of each elastic abutment member 300 away from the microporous sound-absorbing plate 100 abut against the two walls of the corresponding abutment groove 201, and each elastic abutment member 300 abuts against the bottom of the corresponding abutment groove 201, so that the part of the elastic abutment member 300 protruding from the side wall of the microporous sound-absorbing plate 100 extends into the abutment groove 201. With each elastic abutment member 300 configured to elastically expand and contract along the thickness direction of the microporous sound-absorbing plate 100, the sound-absorbing plate and the elastic abutment member 300 are elastically engaged in the abutment groove 201, which better ensures the installation stability of the microporous sound-absorbing plate 100 in the installation, and the installation operation is simple, effectively improving the cleaning convenience of the microporous sound-absorbing plate 100.

[0047] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
