[0002] Screens, as traditional space partitions, have been widely used in offices, homes, and various commercial spaces. However, as people's demands for spatial aesthetics and functionality continue to increase, the limitations of traditional screens in terms of sound absorption, mobility, and aesthetic design are gradually becoming apparent.

[0003] Through searching and analyzing existing patent technologies, we found that existing screen technologies mainly have the following shortcomings: Limited sound absorption function: Most sound-absorbing screens on the market use a single sound-absorbing material or structure, using only ordinary sound-absorbing panels, which have limited absorption effect on mid-to-high frequency sounds and lack antibacterial function.

[0004] Low functional integration: Most screens have only one function, providing only basic partitioning functions, and lack multi-functional integration such as sound absorption, flame retardancy, and antibacterial properties.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a mobile circular screen with an antibacterial, flame-retardant, and sound-absorbing board structure, making it more valuable for industrial use. Utility Model Content

The movable casters 3 are detachably installed on the movable base 2 by a press-type latch and spring pin (not shown separately in the figure), which facilitates future replacement or maintenance.

[0028] The screen unit is composed of two semi-circular screens 4 spliced ​​together. A quick-release block 6 is provided on the inner side of the screen 4. A quick-release groove 5 distributed vertically is provided on the top inner side of the support frame 1. The quick-release block 6 is inserted into the quick-release groove 5 vertically. A clamping component 7 is installed on the top of the support frame 1.

[0029] The clamping assembly 7 includes a clamping top plate 9, on which a handle 10 is provided for easy gripping and application of force, facilitating the installation of the clamping assembly. A downward-protruding pressure block 11 is provided at the bottom of the clamping top plate 9, which inserts into the quick-release slot 5 and contacts the top of the lower quick-release block 6.

[0035] Porous sound-absorbing layer 16: Made of high-density polyester fiber sound-absorbing cotton or honeycomb cardboard, the interior is filled with a large number of interconnected tiny pores to effectively dissipate sound energy and reduce noise.

[0036] Porous foam iron backing layer 17: The innermost layer, which is an open-cell foam metal with a gradient pore structure. This layer not only has high strength, but its unique foam structure can greatly increase the sound wave propagation path. It converts sound energy into heat energy through friction and viscosity, and has a particularly good absorption effect on low-frequency noise. At the same time, it serves as a backing plate for protection.

[0037] A magnetic metal sheet is also embedded in the velvet veneer layer 13, which forms a magnetic attraction area on the surface of the screen 4, allowing the screen surface to attract magnetic items and expand its display and recording functions.

[0038] A curved LED light strip is installed on screen 4, and the curved LED light strip is powered by a USB interface. The curved LED light strip uses low voltage power supply and the interface is a standard USB Type-C interface, which can be powered by common USB power adapters or power banks to create ambient lighting.

[0039] Installation process: Secure the movable base 2 to the support frame 1 with screws, and snap the movable casters 3 into the mounting base of the movable base 2. When you hear a click, the installation is complete.

[0040] Lift the two semi-circular screens 4 vertically so that the quick-release blocks 6 on their inner sides are aligned with the quick-release slots 5 on the support frame 1.

[0041] Place the screen 4 downwards so that the quick-release block 6 falls completely into the bottom of the quick-release slot 5.

[0042] Align the pressure block 11 and positioning post 12 of the clamping assembly 7 with the uppermost quick-release block 6 and its positioning hole 8, and fasten the clamping top plate 9 to the top of the support frame 1 with screws. At this time, the pressure block 11 presses down to tighten the quick-release block 6, the positioning post 12 is inserted into the positioning hole 8, and the screen unit is firmly locked.

[0043] Usage process: Movement: Release the brake mechanism of the moving caster 3 to easily push the screen to the desired position.

[0044] Positioning: Once the screen reaches the designated position, press the brake mechanism of the movable caster 3 to fix it in place.

[0045] Functions and uses: The screen can effectively isolate and absorb environmental noise; its flame-retardant and antibacterial surface is easy to clean and maintain; materials can be pasted on the magnetic surface; it can be connected to a USB power source to light up LED light strips and create a comfortable lighting environment.

[0046] Disassembly and reassembly process: Unscrew the screws securing the top plate 9 and remove the clamping assembly 7.

Antibacterial Coating 14: Nano-titanium dioxide (TiO2) coating, applied to the inner side of the colored velvet finish layer using a roller coating process, with a dry film thickness of 8-12 μm. Tested according to GB / T 21866-2008, it exhibits an antibacterial rate of ≥99% against Escherichia coli and Staphylococcus aureus, and also possesses photocatalytic self-cleaning function. The nano-TiO2 coating is activated under indoor natural light, continuously inhibiting surface bacterial growth, and retains ≥95% of its antibacterial properties after daily wiping.

[0049] Flame-retardant substrate layer 15: Flame-retardant medium-density fiberboard (MDF FR), 12mm thick, conforming to EN 13501-1 B-s2, d0 flame-retardant standard (no burning drips, smoke toxicity level d0), formaldehyde emission ≤0.124mg / m³ 3 (E1 grade), and at the same time serves as a structural load-bearing layer to enhance the rigidity of the screen. Porous sound absorber 16: Two options are available: 1) Honeycomb cardboard (pore size 10mm, wall thickness 0.3mm, noise reduction coefficient NRC=0.75, sound absorption level II); 2) Polyester fiber sound-absorbing cotton (density 60kg / m³). 3 (10mm thick, 0.6-0.8 sound absorption coefficient at 250-2000Hz) converts heat energy through friction with sound waves via a porous structure.

[0050] Porous foamed iron backing layer 17: Gradient pore structure foamed iron, thickness 3mm, porosity 95%-98% (pore size gradually changes from 0.1mm on the surface to 10mm in the inner layer), open porosity ≥98%, bulk density 0.4g / cm³ 3 It absorbs low-frequency sound waves of 100-500Hz through resonance effect, while enhancing the overall heat dissipation of the board.

[0051] During negotiations, human voices (500-2000Hz) enter the honeycomb cardboard through the colored velvet veneer layer and are absorbed by pore friction (sound absorption coefficient 0.8); low-frequency noise from the air conditioner (150Hz) is attenuated by resonance through the foam iron backing layer, and the measured noise inside the screen is 20dB lower than that outside.
