Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sound-absorbing lampshades, and in particular to a disc lamp sound-absorbing lampshade with a flame-retardant sound-absorbing plate structure. Background Technology
[0002] Traditional lampshades have a relatively limited function, only providing basic light transmission and focusing. They cannot cope with the diverse noise pollution in modern home environments (such as low-frequency appliance noise and high-frequency human voice interference). Furthermore, their sound-absorbing structures are mostly made of a single material layer, resulting in poor adaptability to different noise frequencies. In addition, traditional lampshades are mostly made of ordinary fabric or plastic, which have problems such as poor flame retardancy, easy dust accumulation, and insufficient antibacterial properties. Moreover, their installation and disassembly are complicated, making them inconvenient for cleaning and maintenance.
[0003] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a disc lamp sound-absorbing lampshade with a flame-retardant sound-absorbing panel structure, so as to make it more valuable for industrial use. Utility Model Content
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a disc lamp sound-absorbing lampshade with a flame-retardant sound-absorbing panel structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A disc lamp sound-absorbing lampshade with a flame-retardant sound-absorbing panel structure includes a lampshade assembly and at least one suspension connection assembly mounted on the top of the lampshade assembly.
[0007] The lampshade assembly includes a cylindrical lampshade body, which is composed of a colored velvet decorative layer, a flame-retardant substrate layer and a breathable protective layer from the outside to the inside.
[0008] A gradient sound-absorbing layer is installed on the inner side of the flame-retardant substrate layer. The gradient sound-absorbing layer consists of at least two polyester fiber colored velvet sublayers with different porosities, and the porosity of each polyester fiber colored velvet sublayer increases in a gradient along the noise propagation direction.
[0009] As a further improvement of this utility model, a lampshade suspension connection part for matching with the suspension connection assembly is installed at the top center of the lampshade body.
[0010] As a further improvement of this utility model, a circular light-transmitting hole is provided on the inner side of the bottom of the lampshade body.
[0011] As a further improvement of this utility model, the colored velvet decorative layer is made of environmentally friendly recycled polyester fiber.
[0012] As a further improvement of this utility model, a nano-sized magnesium hydroxide flame retardant is embedded in the flame retardant substrate layer.
[0013] As a further improvement of this utility model, the breathable protective layer is a polytetrafluoroethylene microporous membrane.
[0014] As a further improvement of this utility model, the polyester fiber colored velvet sublayer has two layers. The porosity of the first polyester fiber colored velvet sublayer is 85%~90% and the thickness is 3~5mm. The porosity of the second polyester fiber colored velvet sublayer is 60%~70% and the thickness is 5~10mm.
[0015] As a further improvement of this utility model, a detachable decorative module is also installed on the outside of the lampshade body. The detachable decorative module is magnetically attached to the lampshade body.
[0016] As a further improvement of this utility model, the detachable decorative module includes one or more combinations of magnetic adsorption tassels, pleated patches and three-dimensional velvet flowers.
[0017] As a further improvement of this utility model, several temperature-sensitive color-changing strips are also installed on the outside of the lampshade body.
[0018] By means of the above solution, this utility model has at least the following advantages:
[0019] This invention provides basic structural strength and flame-retardant safety performance through a flame-retardant substrate layer, a soft touch and decorative effect through a colored velvet decorative layer, and a breathable protective layer to prevent dust from entering the sound-absorbing layer without affecting sound transmission, resulting in good overall performance.
[0020] This invention improves low-frequency sound absorption capability by installing a gradient sound-absorbing layer on the inner side of the flame-retardant substrate layer, resulting in a wide-band noise absorption coefficient of ≥0.85 in the 200~3500Hz range. Compared with traditional lampshades (which only have a sound absorption coefficient of 0.8 in the 400~2800Hz band), this invention improves low-frequency sound absorption capability by more than 30%, and can simultaneously cope with low-frequency noise from household appliances and high-frequency human voice interference, making it applicable to a wider range of scenarios.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0032] The first embodiment of this utility model:
[0033] like Figures 1-4 As shown, a disc lamp sound-absorbing lampshade with a flame-retardant sound-absorbing panel structure in this embodiment includes a lampshade assembly 1 and at least one suspension connection assembly 2 installed on the top of the lampshade assembly 1.
[0034] The lampshade assembly 1 includes a cylindrical lampshade body. A lampshade suspension connection part 3, adapted to the suspension connection assembly 2, is installed at the top center of the lampshade body. A circular light-transmitting hole 4 is provided on the inner side of the bottom of the lampshade body. The bottom of the suspension connection assembly 2 can be detachably connected to the lampshade suspension connection part 3, and the light-transmitting hole 4 can be used for light transmission of the lamp.
[0035] Among them, at least one mounting structure of the aforementioned suspension connection assembly 2:
[0036] It adopts a combination structure of lifting rod + angle joint + quick-release buckle. The metal lifting rod achieves stepless height adjustment from 0 to 30cm through the spiral engagement of the internal threaded sleeve and the outer rod; the angle adjustment joint has a built-in damping pivot, which can fix the lampshade at an angle of 0 to 45 degrees to adapt to different lighting areas (such as sofa area, bedside area); the quick-release buckle and the top slot of the lampshade adopt a one-button press unlock design, which can be quickly disassembled and assembled without tools, and is easy to clean.
[0037] The lampshade body is composed of a colored velvet decorative layer 11, a flame-retardant substrate layer 12, and a breathable protective layer 13 from the outside to the inside.
[0038] The colored velvet decorative layer 11 is made of environmentally friendly recycled polyester fiber, with a recycled component ratio of ≥60%, and the surface is treated with antibacterial agents, with an antibacterial rate of ≥99% against Escherichia coli and Staphylococcus aureus.
[0039] The flame-retardant substrate layer 12 contains nano-grade magnesium hydroxide flame retardant with an oxygen index ≥32% and has passed GB 8624-2012 B1 level flame retardant certification.
[0040] The breathable protective layer 13 is a polytetrafluoroethylene microporous membrane with an air permeability ≥500g / (m²). 2 • 24h) can block dust from entering the gradient sound-absorbing layer.
[0041] A gradient sound-absorbing layer is installed on the inner side of the flame-retardant substrate layer 12. The gradient sound-absorbing layer is composed of at least two polyester fiber colored velvet sub-layers with different porosities, and the porosity of each polyester fiber colored velvet sub-layer increases in a gradient along the noise propagation direction.
[0042] The polyester fiber colored velvet sublayer consists of two layers. The first layer (high-frequency sound-absorbing sublayer) has a porosity of 85%–90% and a thickness of 3–5 mm. The second layer (low-frequency sound-absorbing sublayer) has a porosity of 60%–70% and a thickness of 5–10 mm. The sound absorption coefficient is ≥0.85 within the noise frequency range of 200–3500 Hz, with a low-frequency absorption coefficient ≥0.82 (200–800 Hz) and a high-frequency absorption coefficient ≥0.88 (1000–3500 Hz).
[0043] This embodiment innovatively employs a high-frequency + low-frequency dual-layer gradient design, bonded to the inner side of the middle flame-retardant substrate. The high-frequency sound-absorbing sublayer (85%~90% porosity, 3~5mm thickness) targets high-frequency noise (1000~3500Hz, such as human voices and high-frequency noise from household appliances), capturing sound waves through dense micropores; the low-frequency sound-absorbing sublayer (60%~70% porosity, 5~10mm thickness) targets low-frequency noise (200~800Hz, such as the operating noise of air conditioners and refrigerators), achieving sound wave resonance dissipation through larger pores. The synergistic effect of the dual sublayers results in a sound absorption coefficient ≥0.85 across the entire frequency range (200~3500Hz), solving the problem of poor adaptability of traditional single sound-absorbing layers.
[0044] A detachable decorative module is also installed on the outside of the lampshade body, which is magnetically attached to the lampshade body. The detachable decorative module includes one or more combinations of magnetic tassels, pleated patches, and three-dimensional velvet flowers. It is connected to the outer colored velvet decorative layer by a hidden magnetic strip and can be replaced individually.
[0045] Several temperature-sensitive color-changing strips are also installed on the outside of the lampshade. The color-changing strips are made of thermochromic material, and they change from colorless to red when the inner layer temperature exceeds 60°C, indicating that the heat dissipation channel needs to be cleaned.
[0046] The second embodiment of this utility model:
[0047] In this embodiment, the outer layer of the lampshade body is made of beige colored velvet decorative layer 11 (65% recycled content), gradient sound absorption layer (4mm high-frequency sound absorption sub-layer, 8mm low-frequency sound absorption sub-layer), and suspension connection component 2 (maximum extension of the lifting rod is 30cm).
[0048] Installation and Operation: Connect the lampshade to the suspension assembly using the quick-release clips. Adjust the lifting rod to a height of 2.5m from the ground, and fix the lampshade at a 15-degree angle (facing the sofa area). After turning on the power, the intelligent control module automatically activates: When people are talking in the living room (noise level 60~70dB, 1000~2000Hz), the noise sensor detects excessive noise, and the high-frequency sound-absorbing sublayer efficiently absorbs human voice noise, reducing the indoor noise level to below 45dB.
[0049] The third embodiment of this utility model:
[0050] In this embodiment, the outer layer of the lampshade body is made of white velvet decorative layer 11 (60% recycled content), gradient sound absorption layer (5mm high-frequency sound absorption layer and 5mm low-frequency sound absorption layer), and adjustable hanging assembly (fixed angle of 30 degrees facing the desk).
[0051] Installation and Operation: Hang the lampshade above the desk, adjusting the height to 1.2m from the desktop. When the computer generates high-frequency fan noise (2000~3000Hz, 45dB), the high-frequency sound-absorbing sublayer quickly captures the sound waves, achieving a sound absorption coefficient of 0.88, reducing the noise level in the desk area to below 38dB. Periodically remove the lampshade using the quick-release clips; simply clean the inner breathable protective layer for easy maintenance.
