[0033] It should also be understood that the terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. As used in the description of the present utility model and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0034] It should be further understood that the term "and / or" used in the description of the present utility model and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0035] Please refer to Figures 1 to 5 , the device can be connected to a pipeline with noise propagation to perform noise cancellation on the noise output by the pipeline, so as to perform noise cancellation on the noise generated during the equipment production process, reduce the noise, and reduce the noise propagation, thereby improving the working environment.

[0036] Please refer to Figures 1 to 6 , a mobile noise cancellation device, comprising: a sound-absorbing box body 10, a throttle plate structure 30, sound-absorbing cotton, and a connector 20. A sound-absorbing cavity is provided in the sound-absorbing box body 10. The throttle plate structure 30 and the sound-absorbing cotton are respectively placed in the sound-absorbing cavity. The connector 20 is connected to the sound-absorbing box body 10, and the connector 20 communicates with the sound-absorbing cavity; the connector 20 is connected to an air flow pipeline with noise propagation in the equipment, and a plurality of sound-absorbing holes 33 are provided on the throttle plate structure 30.

[0037] The noise propagated by the air flow pipeline with noise propagation in the equipment enters the sound-absorbing cavity through the connector 20, diffuses through the sound-absorbing holes 33, and is combined with the sound-absorbing cotton for noise cancellation, so as to achieve the purpose of reducing noise and improving the working environment.

[0038] Among them, the sound-absorbing box body 10 is formed by enclosing an upper top plate, side plates and a bottom plate.

[0039] Specifically, the presence of the sound-absorbing holes 33 changes the path and speed of the air flow, causing the air flow to diffuse and disperse when passing through the throttle plate. This sudden change in cross-sectional area makes the propagation path of the noise complex, and part of the noise energy is effectively scattered or redirected, thereby reducing the noise intensity.

[0040] The sound-absorbing cotton has good sound-absorbing performance. It absorbs the energy of the sound wave, reduces the reflection and propagation of the sound wave, and further attenuates the noise in the sound-absorbing cavity.

[0041] The connector 20 connects the muffler box 10 to the air flow duct with noise propagation, ensuring that noise enters the muffler cavity through the duct. Due to the design of the muffler box 10, when the noise enters the muffler cavity, it will be processed by the throttle plate and sound-absorbing cotton, and part of the noise will be attenuated or reflected back into the duct, thus reducing the noise transmitted from the air flow duct to the outside.

[0042] The above device effectively reduces the propagation of noise by changing the path of the air flow, utilizing the discontinuity of the acoustic impedance, and the function of the sound-absorbing material.

[0043] In one embodiment, refer to Figures 6 to 8 , the above throttle plate structure 30 includes a first throttle plate 31 and a second throttle plate 32, and the muffler holes 33 on the first throttle plate 31 are arranged staggeredly with the muffler holes 33 on the second throttle plate 32.

[0044] The muffler holes 33 on the first throttle plate 31 are staggered with the muffler holes 33 on the second throttle plate 32. This arrangement effectively avoids the situation where noise directly penetrates through the throttle plate holes. The staggered hole positions make the air flow need to bypass more obstacles when passing through, increasing the path length of the noise, which helps to enhance the noise attenuation effect.

[0045] In one embodiment, refer to Figures 6 to 8 , Figure 9 and Figure 10 , the above first throttle plate 31 and second throttle plate 32 are arranged staggeredly in the muffler cavity.

[0046] The first throttle plate 31 and the second throttle plate 32 are arranged staggeredly, so that the air flow experiences multiple direction changes when passing through. This structure can effectively disperse and reduce the noise energy in the air flow. The staggered arrangement increases the complexity of the propagation path of the sound wave in the muffler cavity, making the noise more easily absorbed and attenuated.

[0047] In one embodiment, refer to Figures 6 to 8 , sound-absorbing cotton is placed between the above first throttle plate 31 and second throttle plate 32.

[0048] The sound-absorbing cotton is placed between the first throttle plate 31 and the second throttle plate 32. This position can effectively absorb the noise entering through the throttle plate holes. The fiber structure of the sound-absorbing cotton can absorb and block the energy of the sound wave, reducing the reflection and propagation of noise in the muffler cavity.

[0049] Through the design of throttle plates with staggered and interleaved arrangements, the noise passes through a more complex path, reducing the direct propagation, thereby improving the noise attenuation effect; the placement of sound-absorbing cotton further enhances the noise absorption rate, enabling more effective reduction of the noise generated by the equipment; the staggered arrangement of the throttle plate structure 30 avoids the direct passage of air flow, evenly disperses the air flow when passing through the sound-absorbing cavity, optimizes the contact between the air flow and the sound-absorbing material, and enhances the overall sound-absorbing effect.

[0050] In one embodiment, the above-mentioned connector 20 includes a throttle connector 20.

[0051] In one embodiment, please refer to Figures 1 to 7 , the above-mentioned mobile sound-absorbing device further includes a hub 40 and wheels. The hub 40 is connected below the sound-absorbing box body 10, and the wheels are connected to the hub 40.

[0052] The hub 40 is a support component installed below the sound-absorbing box body 10, on which wheels are installed, enabling the sound-absorbing device to be easily moved. These wheels usually have a rotating shaft, allowing the device to roll smoothly on different surfaces.

[0053] In one embodiment, please refer to Figures 1 to 7 , a brake pad is installed on the hub 40.

[0054] The brake pad is installed on the hub 40 to fix the position of the device. By applying the brake, the wheels can be locked to prevent accidental movement of the device during use. The brake pad fixes the wheels to the ground through friction, increasing the stability of the sound-absorbing device.

[0055] In one embodiment, please refer to Figures 1 to 7 , the above-mentioned mobile sound-absorbing device further includes a handle 50, and the handle 50 is connected above the sound-absorbing box body 10.

[0056] The handle 50 is installed above the sound-absorbing box body 10 for operating and guiding the sound-absorbing device. Users can easily push or pull the sound-absorbing device through the handle 50 to move it between different positions.

[0057] In one embodiment, the material of the sound-absorbing box body 10 is 304 stainless steel, and the sound-absorbing box body 10 is specifically fabricated by laser cutting, programming, bending, and welding of 304 stainless steel.

[0058] In one embodiment, the material of the throttle connector 20 is 304 stainless steel, and the throttle connector 20 can be made of a pipeline and a quick-disconnect female connector.

[0059] In one embodiment, the above-mentioned first throttle plate 31 and the second throttle plate 32 are respectively fabricated by plasma cutting and machining of 5-mm thick steel plates.

[0060] In one embodiment, the material of the above-mentioned sound-absorbing cotton is a flame-retardant knitted felt material.

[0061] The above-mentioned mobile sound-absorbing device combines components such as a sound-absorbing box body 10, a throttle plate structure 30, and sound-absorbing cotton, and has the advantages of simple installation, easy operation, excellent sound-absorbing performance, and long-term use. It is designed to be independently supported, allowing for free expansion during operation and shutdown, thus avoiding applying additional loads to the exhaust pipe and ensuring the safety and reliability of the exhaust system. It can be equipped with special movable connection devices according to design requirements or user needs for easy operation. It is made of high-quality stainless steel and other materials, with excellent high-temperature resistance and corrosion resistance to ensure the durability of the equipment. The connection method between the device and the equipment adopts a joint docking type to achieve rapid switching.

[0062] Specifically, through modular design, each part of the sound-absorbing device (such as the sound-absorbing box body 10, the throttle plate structure 30, the sound-absorbing cotton, the connector 20, etc.) can be independently assembled and disassembled. This design makes the installation and maintenance processes more intuitive and simple. By using the connector 20, the sound-absorbing device can be easily connected or disconnected from the air flow pipe without complex tools or professional techniques.

[0063] Wheels 40 and tires are installed at the bottom of the device, enabling the sound-absorbing device to roll easily on different surfaces. Wheels with brake pads can fix the position of the device when needed to prevent accidental movement.

[0064] A handle 50 is installed on the sound-absorbing box body 10, enabling the operator to easily push or pull the sound-absorbing device and improving the convenience of operation.

[0065] By using a staggered arrangement of the first throttle plate 31 and the second throttle plate 32, the air flow experiences multiple direction changes when passing through, increasing the complexity of the sound wave propagation path, thereby improving the noise attenuation effect.

[0066] Using high-quality sound-absorbing cotton materials, such as flame-retardant knitted felt, can effectively absorb the energy of sound waves and reduce the reflection and propagation of sound waves.

[0067] A number of sound-absorbing holes 33 are designed on the throttle plate to change the path and speed of the air flow, making the noise propagation path more complex and thus reducing the noise intensity.

[0068] The sound-absorbing box body 10 and the throttle connector 20 are made of high-quality materials such as 304 stainless steel, with excellent high-temperature resistance and corrosion resistance, ensuring the durability and long-term stability of the equipment in various environments.

[0069] The sound-absorbing box body 10 and the throttle plate structure 30 undergo precise processing techniques, such as laser cutting and plasma cutting, to ensure the structural firmness and long-term stability.

[0070] Design an independent structure to avoid applying additional loads to the exhaust pipe, prevent unnecessary pressure on the pipe during the operation or shutdown of the device, and thus ensure the safety and reliability of the exhaust system.

[0071] For the above-mentioned mobile silencing device, by setting the silencing box body 10, the throttle plate structure 30, the sound-absorbing cotton and the connector 20, and a number of sound-absorbing holes 33 are provided on the throttle plate structure 30, the noise is input from the connector 20 into the sound-absorbing cavity, and is silenced by the sound-absorbing cotton, and the noise is dispersed through a number of sound-absorbing holes 33 to further reduce the sound intensity, so as to achieve silencing treatment for the noise generated during the equipment production process, reduce the noise, reduce the noise propagation, and thus improve the working environment.
