Description

Technical Field

[0001] This utility model relates to the field of sound insulation device technology, and more particularly to the field of indoor water pipe sound insulation device technology, specifically a noise reduction and sound insulation device for PVC drain pipes in bathrooms. Background Technology

[0002] PVC drainage pipes are made primarily from sanitary-grade polyvinyl chloride resin and are typically used for drainage, particularly in bathrooms. In indoor bathrooms, the upstairs and downstairs units are usually connected by a single set of PVC drainage pipes. Therefore, when a neighbor's bathroom is draining water, the water flows through the upstairs drain pipe and into the upstairs bathroom's drainpipe. The impact between the water and the inner wall of the pipe creates noise. To mitigate this noise, a layer of sound-absorbing and insulating cotton is usually laid on the outside of the PVC drainage pipes.

[0003] In a published Chinese patent application (publication number CN217714117U), titled "Noise Reduction and Sound Insulation Device for PVC Drainage Pipes in Bathrooms," the prior art includes a drainage pipe and sound-insulating cotton covering the outside of the drainage pipe. A protective shell is provided outside the sound-insulating cotton, and the protective shell has a semi-circular cross-sectional shape. The shape of the sound-insulating cotton is adapted to the protective shell. Both ends of the protective shell are provided with insert rods and grooves, which are staggered. While this prior art allows the protective shells to be interlocked, directly fitting onto the outside of the drainage pipe, and multiple sets of protective shells can be interlocked to accommodate drainage pipes of different lengths, simplifying operation and improving the installation efficiency of the sound-insulating cotton, the use of limiting blocks and protrusions to limit the interlocking of the protective shells prevents slippage on the outside of the drainage pipe, allowing the protective shell to drive the sound-insulating cotton to perform sound insulation and noise reduction on the outside of the drainage pipe. However, this prior art has certain limitations in practical implementation. In practice, the gaps in the sound insulation material and the gaps in the protective shell are interconnected, making it easy for noise generated by the drain pipe to leak out through these gaps, thus resulting in limited sound insulation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a noise reduction and sound insulation device for PVC drain pipes in bathrooms, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a noise reduction and sound insulation device for PVC drain pipes in bathrooms, comprising multiple sound insulation components wrapped around the outer wall of the PVC drain pipe, with each component arranged sequentially end-to-end, and the head end of one component detachably connected to the tail end of an adjacent component; each sound insulation component consists of two sound insulation cover assemblies, which together form a cylindrical structure, and are detachably connected; each sound insulation cover assembly includes a shell and at least one sound insulation board, the sound insulation board being disposed on the inner wall of the shell, and the sound insulation board being made of either butyl rubber vibration damping board or sound insulation felt; the shell is made of either plastic or synthetic rubber material.

[0006] The gaps at the joints of the two soundproof panels in the soundproof component are misaligned with the gaps at the joints of the two shells; or, the contact surfaces of the two soundproof cover assemblies in the soundproof component are inclined.

[0007] Optionally, the housing may be made of either PVC or nitrile rubber.

[0008] Optionally, at least one first retaining plate is fixedly connected to the outer wall of one side of the housing, and a protrusion is fixedly connected to the side wall of the first retaining plate near the drain pipe; a first retaining groove is formed on the outer wall of the other side of the housing.

[0009] Optionally, in a soundproofing component, a first latch plate on one housing engages with a first latch groove on another housing.

[0010] Optionally, a second retaining plate is fixedly connected to one side of the outer wall of the housing, and a second retaining groove is provided on the other side of the outer wall of the housing.

[0011] Optionally, in two adjacent sound insulation components, the second locking plate of the housing engages with the second locking groove on the adjacent housing.

[0012] Optionally, one end of the soundproof cover assembly is an inwardly recessed inclined surface, the other end of the soundproof cover assembly is an outwardly convex inclined surface, and both sides of the soundproof cover assembly are inclined surfaces.

[0013] This utility model provides a noise reduction and sound insulation device for PVC drain pipes in bathrooms, which has the following beneficial effects:

[0014] 1. This bathroom PVC drain pipe noise reduction and sound insulation device strengthens sound insulation by misaligning the gaps at the joints of the two sound insulation panels with the gaps at the joints of the two shells. This prevents the gaps in the sound insulation panels from connecting with the gaps in the shells, thus enhancing the sound insulation effect. Compared with existing technologies, this significantly reduces the leakage of noise from the drain pipe through the gaps, greatly improving the sound insulation performance.

[0015] 2. This bathroom PVC drain pipe noise reduction and sound insulation device sets the contact surfaces of the two sound insulation cover components in an inclined manner, so that the gap between the two sound insulation cover components is set at an incline, that is, the gap is not perpendicular to the drain pipe. The noise generated by the drain pipe cannot pass through the gap in a straight line, thus avoiding the possibility of noise leakage from the gap, and greatly improving the sound insulation effect of the drain pipe.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0025] Example 1, please refer to Figures 1 to 5 The present invention provides a technical solution: a noise reduction and sound insulation device for PVC drain pipes in bathrooms, comprising multiple sound insulation components wrapped around the outer wall of the PVC drain pipe in the bathroom, and each sound insulation component is arranged in sequence and connected end to end, with the head end of one sound insulation component being detachably connected to the tail end of the adjacent sound insulation component.

[0026] The sound insulation component consists of two sound insulation cover assemblies, which together form a cylindrical structure. The two sound insulation cover assemblies are detachably connected.

[0027] The two soundproof enclosure components are combined to form a cylindrical structure and then clamped onto the outer wall of the PVC drainage pipe.

[0028] The soundproof enclosure assembly includes a housing 1 and at least one soundproof panel 2. The soundproof panel 2 is disposed on the inner side wall of the housing 1 and is made of either butyl rubber damping board or soundproof felt. The housing 1 is made of either plastic or synthetic rubber material.

[0029] The soundproof enclosure assembly employs a multi-layered soundproofing method to treat the PVC drainage pipe for sound insulation and noise reduction. Both the soundproof panel 2 and the shell 1 serve a soundproofing function. Simultaneously, the shell 1 also provides protection, acting as an outer layer to protect the soundproof panel 2.

[0030] The gap at the joint of the two sound insulation panels 2 in the sound insulation component is misaligned with the gap at the joint of the two shells 1.

[0031] Specifically, by misaligning the gaps at the joints of the two sound insulation panels 2 with the gaps at the joints of the two shells 1, the gaps in the sound insulation panels 2 and the gaps in the shells 1 are not connected, thus enhancing the sealing and sound insulation effect. Compared with existing technologies, this avoids the intensity of noise leakage from the drainage pipe through the gaps, greatly improving the sound insulation effect.

[0032] Specifically, the shell 1 is made of either PVC or nitrile rubber.

[0033] The housing 1 can also be made of other materials depending on the actual implementation needs. The housing 1 includes, but is not limited to, PVC material and nitrile rubber material.

[0034] Specifically, at least one first locking plate 3 is fixedly connected to the outer wall of one side of the housing 1, and a protrusion is fixedly connected to the side wall of the first locking plate 3 near the drain pipe. A first locking groove 4 is formed on the outer wall of the other side of the housing 1. In a sound insulation component, the first locking plate 3 on one housing 1 engages with the first locking groove 4 on the other housing 1.

[0035] In one soundproof component, two housings 1 are assembled using a snap-fit ​​method. The first snap-fit ​​plate 3 has a certain degree of flexibility. The first snap-fit ​​plate 3 can be made of plastic. The protrusion on the first snap-fit ​​plate 3 of one housing 1 snaps into the first slot 4 of the other housing 1.

[0036] Specifically, a second locking plate 5 is fixedly connected to the outer wall of one end of the housing 1, and a second locking groove 6 is provided on the outer wall of the other end of the housing 1. In two adjacent sound insulation components, the second locking plate 5 of the housing 1 engages with the second locking groove 6 on the adjacent housing 1.

[0037] In this configuration, in two adjacent soundproofing components, the second locking plate 5 of housing 1 engages with the second locking groove 6 on the adjacent housing 1, thereby enabling the assembly of the two adjacent soundproofing components. The second locking plate 5 has a certain degree of flexibility. The second locking plate 5 is made of plastic.

[0038] Example 2, please refer to Figures 1 to 5 The main difference between this embodiment and Embodiment 1 is that the contact surfaces of the two soundproof enclosure components in the soundproof component are inclined. One end of the soundproof enclosure component is an inwardly concave inclined surface, and the other end of the soundproof enclosure component is an outwardly convex inclined surface. Both sides of the soundproof enclosure component are inclined surfaces.

[0039] In this design, by setting the contact surfaces of the two soundproof cover components in the soundproofing component to be inclined, the gap between the two soundproof cover components is set at an angle, that is, the gap is not perpendicular to the PVC drain pipe. The noise generated by the PVC drain pipe cannot pass through the gap in a straight line, thus avoiding the possibility of noise leaking out through the gap and greatly improving the sound insulation effect of the drain pipe.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
