The combination of a metal fixing ring and a magnetic ring allows the perforated plate to be directly fixed to the fixing holes on the underside of the laminar flow air supply ceiling by magnetic force, greatly saving installation time. When the perforated plate needs to be disassembled for cleaning, replacement, or repair, only a certain external force needs to be applied to overcome the magnetic attraction of the ring to separate the perforated plate from the metal fixing ring. Therefore, the perforated plate can be easily and quickly disassembled and assembled without additional tools, improving ease of use.

Description

Technical Field

[0001] This utility model belongs to the field of air supply ceiling technology, specifically relating to a sound-insulating laminar flow air supply ceiling. Background Technology

[0002] In cleanrooms, operating rooms, and other places with extremely high environmental requirements, ceiling-mounted air supply systems are key equipment for ensuring indoor air quality and airflow organization. However, traditional ceiling-mounted air supply systems have many problems in practical applications.

[0003] On the one hand, the structural design of traditional air-supply ceiling panels is prone to resonance of the panels themselves and internal components when airflow passes through, generating significant noise. This noise not only affects the comfort of people indoors, but in scenarios such as operating rooms, it may also interfere with the operation and judgment of medical staff, posing a potential threat to medical safety.

[0004] On the other hand, the installation of traditional air-supply ceiling panels is quite cumbersome, usually requiring multiple people to work together and using various tools for positioning and fixing. The installation process is time-consuming and labor-intensive, increasing maintenance costs and workload. Therefore, developing a new type of sound-insulating laminar flow air-supply ceiling that can solve the above problems is of significant practical importance. Utility Model Content

[0005] The purpose of this invention is to provide a soundproof laminar flow ceiling to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A soundproof laminar flow ceiling includes an air supply ceiling body, a base plate with a fixed area on the lower side of the air supply ceiling body larger than the base plate of the air supply ceiling body, an air inlet on the side of the air supply ceiling body, a mounting base installed on the upper side of the base plate, a rubber ring fixed on the lower side of the air supply ceiling body, and the base plate and the air supply ceiling body fixedly connected by the rubber ring. Multiple fixing holes are evenly distributed in the center of the base plate, and metal fixing rings are provided inside the fixing holes. A perforated plate matching the fixing hole and the metal fixing ring is fixed on the lower side of each fixing hole, and a magnet ring matching the metal fixing ring is fixed on the outer side of the perforated plate.

[0008] Multiple elastic rods are evenly fixed to the top inner side of the air supply ceiling body, and a vibrating hammer is fixed to the lower end of each elastic rod.

[0009] The magnet ring is a neodymium magnet strip.

[0010] A soft rubber pad is fixed to the upper side of the magnet ring.

[0011] A sealing ring is fixed to the outer ring of the base plate.

[0012] A ring of lights is installed on the outer bottom of the base plate.

[0013] This soundproof laminar flow ceiling system is connected to the base plate via rubber rings. The rubber rings, with their excellent elasticity and sealing properties, act as a buffer, reducing vibration transmission between the base plate and the ceiling body, thus lowering noise generated by vibration and improving sound insulation. The combination of metal fixing rings and magnetic rings allows the perforated plate to be directly fixed to the fixing holes on the underside of the laminar flow ceiling system via magnetic force, significantly saving installation time. When the perforated plate needs to be disassembled for cleaning, replacement, or maintenance, only a certain amount of external force needs to be applied to overcome the magnetic attraction force to separate the perforated plate from the metal fixing rings. This allows for easy and quick disassembly and assembly without additional tools, improving usability. The elastic rod and vibrating hammer utilize the inertial mass of the vibrating hammer, while the elastic rod converts the mechanical energy of vibration into heat energy for dissipation, thereby counteracting the vibration generated by the ceiling body and further enhancing the quietness of the laminar flow ceiling system. The neodymium magnetic strips have strong attraction (attraction ≥12kg / cm²). 2 This design ensures the perforated plate won't detach, guaranteeing its stability and thus the reliability of the laminar flow ceiling. The soft rubber pad on the upper side of the magnetic ring fills the gap between the perforated plate and the fixing ring, reducing the probability of air leakage and preventing vortex noise caused by airflow leakage from the edge of the perforated plate. The sealing ring on the outer ring of the base plate fills the gap between the base plate and other components of the surrounding ceiling, further reducing the vibration of the laminar flow ceiling and its impact on surrounding components, making the laminar flow ceiling quieter. The lighting installed on the outer ring at the bottom of the base plate provides auxiliary lighting for the operating room, enhancing the functionality of the laminar flow ceiling.

[0021] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-5 As shown, a soundproof laminar flow air supply ceiling includes an air supply ceiling body 11, a base plate 12 with a fixed area larger than the air supply ceiling body 11 on the lower side, an air inlet 13 on the side of the air supply ceiling body 11, an mounting base 14 on the upper side of the base plate 12, a rubber ring 15 fixed on the lower side of the air supply ceiling body 11, and the base plate 12 and the air supply ceiling body 11 are fixedly connected by the rubber ring 15. A plurality of fixing holes 16 are evenly provided in the middle of the base plate 12, a metal fixing ring 17 is provided inside the fixing hole 16, a perforated plate 18 matching the fixing hole 16 and the metal fixing ring 17 is fixed on the lower side of each fixing hole 16, and a magnet ring 19 matching the metal fixing ring 16 is fixed on the outer side of the perforated plate 18.

[0023] In this utility model, the base plate 12 is fixed to the upper side of the ceiling by the mounting base 14, and the air inlet 13 is connected to the external air supply equipment. The soundproof laminar flow air supply ceiling is connected to the base plate 12 by the rubber ring 15. The rubber ring 15 has good elasticity and sealing performance, which can play a buffering role, reduce the vibration transmission between the base plate 12 and the air supply ceiling body 11, reduce the noise caused by vibration, and improve the sound insulation effect. The cooperation between the metal fixing ring 17 and the magnetic ring 19 allows the perforated plate 18 to be directly fixed in the fixing hole 16 on the lower side of the laminar flow air supply ceiling by magnetic force, which greatly saves the installation time. When it is necessary to disassemble the perforated plate 18 for cleaning, replacement or maintenance, only a certain external force needs to be applied to overcome the adsorption force of the magnetic ring 19, and the perforated plate 18 can be separated from the metal fixing ring 17. Therefore, the perforated plate 18 can be easily and quickly disassembled and assembled without additional tools, which improves the convenience of use.

[0024] Multiple elastic rods 21 are evenly fixed to the top inner side of the air supply ceiling body 11, and a vibrating hammer 22 is fixed to the lower end of the elastic rods 21.

[0025] The elastic rod 21 is usually made of elastic steel. The evenly distributed elastic rod 21 and the vibrating hammer 22 on the lower side utilize the inertial mass of the vibrating hammer 22 to convert the mechanical energy of vibration into heat energy for consumption, thereby offsetting the vibration generated by the air supply ceiling body 11, thereby further improving the sound insulation performance of the laminar flow air supply ceiling.

[0026] Magnet ring 19 is a neodymium magnet strip.

[0027] Neodymium magnetic strips have strong attraction (attraction force ≥ 12 kg / cm²). 2 This ensures that the perforated plate 18 will not fall off, thus guaranteeing the stability of the perforated plate 18 and ensuring the reliability of the laminar flow ceiling.

[0028] A soft rubber pad 41 is fixed on the upper side of the magnet ring 19.

[0029] The soft rubber pad 41 on the upper side of the magnet ring 19 can fill the gap between the perforated plate 18 and the fixing ring, thereby reducing the probability of air leakage in the laminar air supply ceiling and preventing vortex noise caused by air leakage from the edge of the perforated plate 18.

[0030] A sealing ring 51 is fixed to the outer ring of the base plate 12.

[0031] A ring of lights 61 is installed on the outer side of the bottom of the base plate 12.

[0032] The sealing ring 51 on the outer ring of the base plate 12 can fill the gap between the base plate 12 and other components of the surrounding ceiling, and can further reduce the vibration of the laminar flow ceiling and its impact on surrounding components, thereby making the laminar flow ceiling quieter. The lighting lamp 61 installed on the bottom outer ring of the base plate 12 can provide auxiliary lighting for the operating room and enhance the functionality of the laminar flow ceiling.

[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
