[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0025] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0027] Referring to the accompanying drawings, a pipeline noise reduction device includes a water inlet body 10, an elastic tube 20, and a support member 30. The elastic tube is cooperatively connected to the support member, which supports the elastic tube, ensuring that the elastic tube cannot be bent, thereby ensuring smooth water flow. The elastic tube can be made of soft rubber or silicone. The outer peripheral wall of the elastic tube and the inner peripheral wall of the water inlet body can be sealed together, thereby achieving a lateral sealing without the need for end face sealing, providing a sealing effect and stability. A sealed gas buffer chamber 40 is formed between the outer periphery of the elastic tube and the inner periphery of the water inlet body. When water flows on the outer periphery of the elastic tube, the gas buffer chamber can buffer the water flow. In other words, when normal water flows into the elastic tube, it will expand outward. However, under the reaction of the closed gas buffer chamber, the water flow is returned through the elastic tube to the elastic tube, achieving noise reduction. Alternatively, when the sound waves generated by the water flow enter this structure, reflection and interference will occur. At the same time, under the action of the sealed gas buffer chamber, some of the sound waves cancel each other, thereby reducing the energy of the sound waves and achieving the purpose of noise reduction. Referring to the accompanying drawings, a notch is provided on the inner circumference of the water inlet body. The notch is located between the two sealing fitting positions of the water inlet body and the elastic tube. The notch forms a gas buffer chamber through sealing with the elastic tube.

[0028] To reduce the generation of sound waves, the inner wall of the elastic tube is provided with rectifier bumps 21. Furthermore, before and after entering the elastic tube, a rectifier net 50 is provided at the water inlet and / or outlet of the elastic tube, which can also effectively reduce the generation of sound waves.

[0029] Preferably, the radial outer walls of the upper and lower ends of the elastic tube can be interference fit with the water inlet body. A notch 31 is provided on the peripheral side wall of the support member, so that the water flow, the elastic tube and the gas buffer chamber can interact stably without any interruption.

[0030] Reference Instructions Figure 1-Figure 3In the first embodiment of the present invention, the elastic tube is provided with a first protruding ring 22 on each of its upper and lower ends. The support member is sleeved around the outer circumferences of the first protruding rings. The outer circumference of the elastic tube between the two first protruding rings and the inner circumference of the support member form a space 60 for the elastic tube to expand outward. The elastic tube is also provided with a second protruding ring 23 on its upper and lower ends. The two first protruding rings are positioned between the two second protruding rings. The second protruding rings can seal against the inner circumferential wall of the water inlet body. A step surface 24 is formed between the first and second protruding rings, and the upper and lower ends of the support member abut against the step surface. The upper and lower ends of the elastic tube are provided with snap-fit portions 25, which are mated with a rectifier mesh.

[0031] Reference Instructions Figure 4-Figure 5 In the second embodiment of the present invention, the elastic tube is sleeved around the outer periphery of the support member. The upper and lower ends of the elastic tube are provided with raised rings 27, which can seal against the inner circumferential wall of the water inlet body. The upper end of the support member is provided with a first outwardly extending boss 32, with the upper end surface of the elastic tube abutting against the lower end surface of the first boss. The lower end of the elastic tube is provided with a second inwardly extending boss 28, with the lower end surface of the support member abutting against the upper end surface of the second raised ring.

[0032] More specifically, the present invention: 1. A closed gas buffer chamber is formed by radial interference sealing of the elastic tube. 2. When the water flow with pressure pulsation passes through the noise reduction device, the elastic tube in the gas buffer chamber that is in contact with the water flow will deform and react to the water flow, consuming the vibration energy of the water flow, thereby suppressing the vibration of the water flow and forming a noise reduction effect. 3. The water inlet and outlet are both designed with a rectifier network with multiple water flow channels, which effectively reduces the pulsation of the water flow velocity and achieves the effect of reducing noise. 4. The better the elasticity of the soft rubber supporting the elastic tube, the better the noise reduction effect, and the gas buffer chamber can also be connected to the atmosphere.

[0033] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
