[0002] A feature wall is a decorative element used in home décor, such as on the walls of the living room, sofa, entryway, and bedroom. A fresh air system, on the other hand, uses mechanical ventilation to force the circulation of indoor and outdoor air. It can continuously expel stale indoor air and introduce purified fresh air even when doors and windows are closed, providing residents or users with a healthy and comfortable breathing environment.

[0003] When integrating a fresh air system into a feature wall, the structural compatibility between the fresh air unit and the feature wall decorative layer is insufficient, lacking an integrated design scheme, and the installation process is relatively complicated. In addition, conventional fresh air units are large, and the feature wall frame and structure require a certain amount of space to accommodate the fresh air unit, resulting in a large space occupation and inconvenient dust accumulation and cleaning of the air vents. At the same time, it will cause air supply vibration and resonance with the overall decorative layer, leading to loosening and cracking at the joints of the decorative layer, which seriously affects the user experience and structural stability. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated fresh air ultra-thin background wall to solve the above problems.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solutions, including: Wall paneling is installed on the outside of the wall using segmented keel suspension for decorating the wall surface; The fresh air unit is installed in the keel cavity formed by the wall and the panel wall, and is used to supply air and purify the air. The fresh air unit is connected to the ventilation vent through an air supply duct, which is laid horizontally along the inside of the keel cavity. The panel wall includes a background wall, and a sound insulation and vibration damping component is provided between the background wall and the air supply duct and / or the wall.

In this invention, a composite felt layer is provided between the background wall and the wall and / or the air supply duct, a composite air layer is provided between the air supply duct and the wall, and a shock absorber layer is provided between the background wall and the segmented keel.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figures 1-7 As shown, in one embodiment, an integrated fresh air ultra-thin background wall includes: a panel wall covering 100 and a fresh air unit 400; For example, the panel wall 100 adopts a segmented hanging installation structure, which is suspended and fixed to the outside of the wall 300 through customized segmented keel 200. The keel spacing is precisely matched according to the size of the fresh air unit 400 and the decoration requirements, which not only ensures the installation stability of the panel wall 100, but also reserves reasonable installation space for the internal fresh air equipment. Meanwhile, as the main decorative element for interior walls, Panel Wall 100 allows users to choose different materials such as gypsum board, slab, and wood veneer to meet diverse decorative styles. In addition, the fresh air unit 400 is integrated into the keel cavity formed by the wall 300 and the panel wall 100. The cavity is divided and reinforced by the segmented keel 200 to form an independent equipment installation space, which not only avoids the fresh air unit 400 being directly exposed and affecting the decorative effect, but also reduces the noise leakage during equipment operation through the cavity structure. The airflow output end of the fresh air unit 400 is connected to the preset ventilation vent 600 through the air supply duct 500. The air supply duct 500 is laid horizontally inside the keel cavity, and the direction of the duct is adapted to the distribution of the keel, ensuring smooth airflow without occupying additional effective indoor space, thus achieving an optimized balance between equipment installation and space utilization.

[0021] In some embodiments, the panel wall 100 includes a background wall 110 made of commonly used decorative materials such as gypsum board, fiber cement board, and solid wood veneer. Its thickness is determined according to the structural strength requirements, ensuring both the flatness and aesthetics of the decorative layer and providing a certain level of basic sound insulation performance. To further enhance the vibration reduction and noise reduction effect, a sound insulation and vibration damping component 120 is provided between the background wall 110 and the air supply duct 500 and / or between the background wall 110 and the wall 300. This component can be flexibly configured according to the actual installation scenario to block the vibration transmission path and lay the foundation for subsequent noise reduction design.

[0022] Understandably, the development of the dedicated fresh air unit 400 for the background wall 110 achieves precise adaptation between the equipment and the decorative layer structure. The external dimensions of the fresh air unit 400 are customized according to the internal space parameters of the keel cavity. The position and size of its ventilation interface perfectly match the reserved holes of the segmented keel 200 and the air outlet position of the panel wall 100, forming a standardized modular docking structure. During on-site installation, there is no need for additional cutting, drilling, or modification of the keel frame or panel wall 100. It only needs to be assembled and fixed according to the preset installation points, effectively reducing on-site adjustment procedures and greatly improving installation efficiency. At the same time, the modular adaptation design avoids the installation gap between the equipment and the decorative layer in traditional integrated solutions, ensuring the tightness and stability of the connection between the two, which not only improves the integrity of the overall structure and effectively reduces on-site adjustment procedures, but also effectively improves the compatibility between the panel wall 100 and the fresh air unit 400.

[0023] In some embodiments, the composite felt layer 121 is made of high-density sound insulation felt (surface density ≥3kg / ㎡), and its overlap width is strictly controlled to ≥50mm. The felt layer absorbs vibration energy through its own damping characteristics and suppresses the propagation of resonance waves. According to actual tests, this structure can reduce the operating noise of the equipment to ≤35dB and reduce the vibration transmission efficiency by 80% compared with the traditional solution, thus achieving the indoor quiet standard.

[0024] Correspondingly, a composite air layer 122 is set between the air supply duct 500 and the wall 300. The air layer has a built-in pyramid-shaped sharp-corner sound-reflecting plate. The sound-reflecting plate is made of flame-retardant foam material and the sharp-corner angle is designed to be 45°. By reflecting and absorbing low-frequency vibration waves from multiple angles, it further weakens the low-frequency noise generated by the operation of the fan and avoids structural abnormal noise caused by low-frequency resonance. In addition, the segmented keel 200 is fixedly connected to the wall 300 by expansion bolts and other expansion components. A shock absorber layer 123 is set between the background wall 110 and the segmented keel 200. JGD type rubber shock absorbers can be used. This type of shock absorber has good elastic recovery performance and damping characteristics. During installation, the rated load is accurately matched according to the actual weight of the fresh air unit 400. For example, for a fresh air unit 400 weighing 100kg, a shock absorber with a rated load of 150kg is selected, with a 50% safety margin reserved. This can effectively support the overall weight of the fresh air unit 400 and the background wall 110, and can also absorb the vibration energy generated by the operation of the equipment through the elastic deformation of the rubber material, completely blocking the transmission path of vibration to the decorative layer through the keel.

[0025] Understandably, the combination of low-noise fans and vibration-damping structures can effectively reduce equipment operating noise and absorb more than 90% of vibration energy, preventing vibration from being transmitted to the decorative layer through the keel and causing resonance. This ensures the overall structural stability of the background wall 110, eliminates abnormal noises and potential safety hazards caused by resonance, and completely solves the problem of resonance in the decorative layer.

[0026] In some embodiments, the duct is made of high-strength galvanized steel sheet with a thickness of 0.6mm, which ensures the structural strength of the duct, prevents deformation caused by airflow impact, and provides good corrosion resistance and sealing performance. The inner diameter of the duct is designed to be 120mm, and the laying distance is strictly controlled. The horizontal distance between the supply air duct 500 and the fresh air outlet 460 of the fresh air unit 400 is ≤300mm, which shortens the airflow transmission path and reduces airflow loss. The duct cross-section adopts a rectangular design, and its width-to-height ratio is strictly controlled within the range of less than 1.2:1. This ratio has been optimized through fluid dynamics simulation, which can reduce the turbulence phenomenon in the airflow within the duct. Compared with traditional circular ducts or rectangular ducts with unbalanced width-to-height ratios, it can increase the ventilation volume by about 20%, while the wind resistance change is controlled to less than 3%, achieving a balance between increased airflow and reduced energy consumption. The height-to-width ratio of the air duct can be flexibly adjusted according to the shape and space of the keel cavity. For example, the height can be appropriately compressed and the width increased in narrow areas to ensure that the air duct can be laid in close to the keel distribution without taking up extra space. Because the airflow direction and velocity of the inlet and outlet air duct 500 are different, when multiple duct sections are connected as a whole, the airflow counterbalances each other, which can significantly reduce the vibration of the duct itself. After the gypsum board ceiling is closed, the sealed space formed by the ceiling structure and the duct can further play a sound insulation role, reducing the overall operating noise by another 15%, achieving a double noise reduction effect.

[0027] Understandably, by optimizing the hydrodynamic characteristics of the air supply duct 500, vibration energy can be effectively absorbed, preventing vibration from being transmitted to the background wall 110 through the segmented keel 200 and causing resonance, thus ensuring the overall structural stability of the background wall 110 and eliminating abnormal noises and potential safety hazards caused by resonance.

[0028] In some embodiments, a high-efficiency thermal insulation layer is filled between the air supply duct 500 and the segmented keel 200. This thermal insulation layer is made of centrifugal glass wool or polyurethane foam, with a thermal conductivity ≤0.038W / (m²). K) has excellent thermal insulation performance, which can effectively reduce the heat exchange between the airflow in the duct and the indoor environment, avoid the problem of excessively low supply air temperature in winter and excessively high supply air temperature in summer, reduce air conditioning energy consumption, and achieve energy saving effect. During the filling process, the insulation layer completely fits the gap between the outer wall of the air duct and the keel, which can play a role in fixing the air supply duct 500, preventing the air duct from shifting or misaligning during equipment operation or long-term use, and solving the misalignment problem caused by poor compatibility between the equipment and the wall 300 in the traditional solution.

[0029] In some embodiments, an ultraviolet lamp assembly is embedded at the end of the air supply duct 500. The ultraviolet lamp is a UVC deep ultraviolet lamp with a wavelength of 254nm, and its irradiation range covers the air outlet area of ​​the duct. When fresh air flows through, it can quickly kill bacteria, viruses, mold and other microorganisms in the air, while inhibiting the growth of bacteria on the inner wall of the duct and at the air outlet. This design can not only improve the quality of the supplied air, but also reduce the problem of dust accumulation and odor caused by bacterial growth, and provide convenience for subsequent cleaning and maintenance, indirectly solving the problem of inconvenient cleaning of dust accumulation at the air outlet.

[0030] In some embodiments, the air supply duct 500 and the ventilation vent 600 are sealed and connected by a metal sleeve 700. The metal sleeve 700 is made of stainless steel, and its outer diameter is precisely matched with the inner diameter of the duct. The length of the sleeve is set according to the thickness of the wall 300, ensuring that one end of the sleeve is tightly connected to the duct, and the other end extends into the wall 300 and is fixed to the ventilation vent 600. The metal sleeve 700 can enhance the structural strength of the connection between the duct and the vent, and prevent the connection from loosening due to airflow impact. At the same time, the stainless steel material has good sealing properties to prevent airflow leakage. A rainproof cap 800 is provided on the outside of the ventilation vent 600. The cap is made of ABS engineering plastic, and its arc-shaped structure design can effectively prevent outdoor rainwater from flowing back into the duct. It can also intercept large particles of dust and debris from the outside, preventing them from entering the fresh air unit 400 and affecting the operation of the equipment. It plays a dual role of protection and dust prevention, and further ensures the long-term stable operation of the fresh air system.

[0031] Understandably, the design incorporates magnetic or snap-on detachable air vents. The vent frame is fixed to the panel wall 100 via magnetic attraction or snap-on fastening, allowing users to easily remove the vent without the need for screwdrivers or other specialized tools, simply by gently pulling it manually. This makes the operation convenient and efficient. The modular design, with its embedded UV light, detachable dust cover, and adjustable vent aspect ratio, allows for direct replacement without cleaning. The slender vent shape increases both airflow and return volume while reducing air velocity, preventing dust and hair from accumulating on the vent and solving the problem of difficult-to-clean dust accumulation in traditional vents. This effectively extends the internal cleaning cycle of the equipment, reduces maintenance costs, and enhances the user experience.

[0032] In some embodiments, the fresh air unit 400 includes a fresh air body, the outer shell of which is made of aerospace-grade aluminum alloy material and formed by precision die casting process. It has both excellent structural strength and achieves an extremely lightweight design. The thickness of the outer shell is strictly controlled to ≤80mm, providing core support for the ultra-thin background wall 110. The fresh air body is customized according to the actual size of the keel cavity. The surface of the outer shell is pre-set with standardized mounting holes. The spacing of the holes is precisely matched with the spacing of the segmented keel 200. During installation, the fresh air body is detachably fixed to the galvanized steel plate segmented keel 200 in the middle of the keel cavity of the background wall 110 through stainless steel bolts and other connectors, forming a strong rigid connection.

[0033] Understandably, the use of the ultra-thin fresh air unit 400 to replace traditional fresh air equipment is appropriate. Its width matches the keel spacing, and with the integrated flat air supply duct 500, the overall height is only 120mm, which can be embedded in a standard keel cavity with a width of 200mm, without the need to widen the wall 300. This keeps the total thickness of the background wall 110 within 120mm, which reduces the space occupied by 40% compared to the traditional solution with a thickness of ≥200mm, meeting the space requirements of small apartments. Therefore, the miniaturized and integrated fresh air unit 400 design reduces its thickness to half that of traditional equipment. By optimizing the nesting structure between the background wall 110 keel and the equipment, no additional installation space is required, effectively reducing the overall thickness of the background wall 110. While ensuring fresh air volume, this design effectively improves space utilization, making it particularly suitable for small apartments or scenarios with high space requirements. At the same time, by integrating multiple professional technical requirements and developing a standardized installation manual, the installation process, which originally required the cooperation of 3-4 professional trades, can be simplified to be completed by 1-2 specially trained construction teams. The installation cycle is shortened from 3-5 days to 1-2 days, reducing labor costs by 40%-50%. Furthermore, standardized operations reduce human error and improve the stability of installation quality.

[0034] In some embodiments, a first filter 410 is provided on one end face of the fresh air unit. The first filter 410 is a pre-filter (G4 grade), which mainly intercepts large particles of dust, hair, and other impurities in the air. A second filter 420 is provided on one side of the first filter 410. The second filter 420 is a HEPA high-efficiency filter (H13 grade), which can filter PM2.5, fine particulate matter, etc., with a filtration efficiency of ≥99.97%. An exchange core 430 is provided on one side of the second filter 420. The exchange core 430 is a total heat exchange core 430, made of hydrophilic aluminum foil or paper substrate, which can recover the temperature of the exhaust air. The system incorporates humidity control, allowing fresh air to exchange energy with exhaust air before entering the room, reducing the energy consumption of air conditioning or heating. A third filter 440, an activated carbon filter, is installed on one side of the exchange core 430 to adsorb harmful gases such as formaldehyde, benzene, and TVOC, removing odors. Fan modules 450 are symmetrically arranged on the outer sides of the first filter 410 and the third filter 440, respectively responsible for fresh air intake and exhaust. Driven by a DC brushless motor, the speed can be intelligently adjusted, and the air volume is automatically adjusted according to the detection data of the indoor air quality sensor to achieve on-demand ventilation, ensuring air quality while avoiding energy waste.

[0035] In some embodiments, the air vent is injection molded from ABS engineering plastic, which has the characteristics of impact resistance, high temperature resistance, and non-aging. The air vent is equipped with a removable dust filter (primary G3 grade) to further intercept dust and impurities in the air and prevent them from entering the fan and exchange core 430, thus extending the service life of the equipment. The outer side of the fresh air vent 460 is fitted with a composite flexible hose 900. The flexible hose is made of PVC and fiber cloth composite material, which has good flexibility and sealing performance and can adapt to slight angle adjustments during installation. The composite flexible hose 900 is securely connected to the air supply duct 500 by a stainless steel hose clamp. The tightening force of the hose clamp is adjustable to ensure that there is no air leakage at the connection. The symmetrically arranged fresh air vents 460 can evenly distribute airflow to each air supply duct 500, ensuring consistent ventilation in different areas of the room and avoiding the problem of insufficient local ventilation.

[0036] In some embodiments, the background wall 110 is equipped with an integrated access panel corresponding to the installation position of the fresh air unit 400. The panel can be designed with an aluminum alloy frame and a magnetic cover to facilitate the maintenance and cleaning of the fresh air unit 400.

[0037] For example, product verification was conducted in the living room of the model room in the product development and testing center after it was dismantled and modified.

[0038] Space surveying and demand matching: First, a precise survey of the site is conducted to record the net dimensions of the living room walls; customized component prefabrication, including custom square air outlet fresh air unit, custom irregular duct, and custom processing of fixed components; installation of fresh air unit and duct, installation of sound insulation and finishing layer, air volume testing and effect evaluation; Experimental Results: Continuous monitoring of the operation data of the fresh air system in the living room of the model room (for 1 month), recording PM2.5 filtration efficiency (≥99%) and equipment failure rate (0 failures), and judging the feedback on the ease of cleaning the air outlet (the time for disassembling and cleaning the magnetic air outlet is ≤2 minutes), providing data support for subsequent product iterations.

[0039] (I) Experimental verification of vibration energy absorption efficiency: Experimental model construction: A 1:1 scale experimental prototype was built in accordance with the "Standard for Vibration Isolation Design of Buildings" (GB / T51408-2021); Experimental group: JGD type rubber shock absorber and shock-absorbing felt pad combination (connection part between equipment and segmented keel) designed according to the scheme, with streamlined integrated air duct (inner wall smoothness Ra≤1.6μm); Control group: traditional rigid connection (equipment directly welded to segmented keel), with straight cylindrical air duct (inner wall Ra=6.3μm); Both groups used the same model of ultra-thin fresh air unit (operating speed 1500r / min, rated vibration acceleration 0.8m / s²).

[0040] Table 1 Comparison of detection indicators between experimental group and control group

[0041] (1) Energy absorption capacity of elastic shock-absorbing pad: Based on the test law of elastic materials, the shock absorption value of a 10mm thick shock-absorbing felt pad can reach more than 45% (far exceeding the upper limit of 28.9% for ordinary yoga mats). Combined with the damping characteristics of JGD rubber shock absorber (absorption efficiency ≥50% under rated load), the two work together to achieve a total absorption efficiency of over 90%. (2) Enhanced efficiency of duct optimization: The secondary vibration caused by airflow turbulence in traditional straight duct accounts for 35% of the total vibration energy of the equipment. The streamlined design reduces this part of the vibration by 90% by eliminating eddies, further improving the overall absorption efficiency.

[0042] (II) Resonance Suppression and Structural Stability Experiments (1) Resonance frequency test: The frequency sweep excitation method (frequency range 1-50Hz) was used. The experimental group had no resonance peak at 12Hz (the natural frequency of the decorative layer), while the control group showed a surge in amplitude at 12Hz (peak value reached 2.1mm), which is consistent with the conclusion that the resonance of 1-10Hz can be effectively eliminated in the semi-active vibration absorber experiment.

[0043] (2) Long-term stability verification: After 1000 hours of continuous operation, there was no visible vibration displacement on the surface of the decorative layer in the experimental group, and the abnormal noise detection value was ≤20dB (below the threshold of human hearing); a 0.8mm gap appeared at the connection between the decorative layer and the keel in the control group, and the resonance noise reached 42dB, posing a risk of panel detachment; (3) Industry standard compliance of experimental data and basis for meeting vibration absorption efficiency standards: The experimental data (92.3%) far exceeds the minimum requirement (equipment vibration isolation efficiency ≥60%) in the "Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering" (GB50243-2016), and is at the same level as the three-level vibration reduction system (absorption efficiency 90%-95%) commonly used in aerospace equipment.

[0044] (4) Resonance control standard fit: The experimental group had no resonance response in the 1-50Hz frequency band, which met the requirement of "indoor structural vibration acceleration of residential buildings ≤0.015m / s²" in the "Indoor Vibration Limits and Measurement Methods of Residential Buildings" (GB / T50355-2018), thus completely eliminating the risk of structural fatigue caused by resonance.
