Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a breathing wall with an acoustic diffusion function. Background Art

[0002] A breathing wall is a ventilation device with air purification capabilities in buildings. It filters, purifies, and conditions air through an air handling system. Then, through the wall's conduction mechanism, it delivers clean, fresh air into the room, achieving excellent indoor air quality. During the breathing wall's ventilation process, the smooth flow of air is crucial for maintaining indoor air quality, protecting human health, and improving production efficiency.

[0003] The audition room is a scene that has certain requirements for air quality and relatively high requirements for acoustics. If central air conditioning is installed, the air outlet of the air conditioning's fresh air system will generate noise when the air enters, which will seriously affect the audition and recording effects. The existence of the breathing wall, if connected to the air conditioning's fresh air system, can solve the impact of the air conditioning system's ventilation noise.

[0004] Existing breathing walls generally only have air filtration, purification and regulation functions, and do not have acoustic diffusion functions. They are not suitable for some special application scenarios, such as listening rooms and recording studios, which have certain requirements for air quality and relatively high acoustic requirements. Therefore, they need to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model proposes a breathing wall with acoustic diffusion function, which can not only improve the air quality but also improve the acoustic diffusion effect, and has a simple structure and diverse functions.

[0006] To achieve the above technical solution, the utility model provides a breathing wall with acoustic diffusion function, including: a hanging bracket installed on a rough wall, a modularly designed acoustic diffusion breathing wall panel installed on the hanging bracket, an air duct installed at the bottom of the rough wall, the acoustic diffusion breathing wall panel and the air duct connected by a ventilation connecting pipe, the acoustic diffusion breathing wall panel includes a filter housing, an acoustic diffusion filter plate installed on the surface of the filter housing, the acoustic diffusion filter plate includes a filter bottom plate and diffusion fins, the filter bottom plate is fixed on the filter housing, and the diffusion fins are installed on the filter bottom plate, and air vents are provided at the upper and lower ends of the filter housing, the air vents of two adjacent filter housings are connected by a hollow module connecting pipe, a connecting air nozzle is installed on the bottom air vent of the filter housing at the bottom, the connecting air nozzle is connected to the air duct through the ventilation connecting pipe, and a vent cover is installed on the top air vent of the filter housing at the top.

[0007] In the above technical solution, the acoustic diffusion breathing wall panels utilize a modular design. Assembly requires only connecting the filter housings via modular connecting pipes, making production and installation extremely convenient. The filter base within the acoustic diffusion filter panels is molded from gypsum with diatomaceous earth and zinc oxide to create a microporous structure of 50-100 nanometers. This structure filters out PM2.5 and PM1.0 dust particles, as well as airborne viruses, bacteria, and other particles larger than 100 nanometers. Zinc oxide kills bacteria and viruses adhering to the surface, providing a sterilizing and mildew-proofing effect. The diffusion fins are made of solid wood and mounted on the surface of the filter base, facilitating sound diffusion within the room. In operation, when the external constant-temperature fresh air system applies positive pressure to the air duct, air enters the filter housing through the ventilation connecting pipe and exits through the surface of the acoustic diffusion filter panels. It is filtered by the filter base within the acoustic diffusion filter panels before being supplied as fresh air to the room. When the external constant-temperature fresh air system applies negative pressure to the air duct, indoor air passes through the acoustic diffusion filter panels, enters the filter housing, and is discharged through the associated piping. During the whole process, the acoustic diffusion filter panel can not only filter the air, but also diffuse the sound in the room.

[0008] Preferably, the hanging rack includes an upper hanging bar and a lower hanging bar spaced apart and arranged side by side, and the upper hanging bar and the lower hanging bar are fixed to the rough wall by angle brackets to facilitate the subsequent installation of the acoustic diffusion breathing wall panel.

[0009] Preferably, the top side end of the acoustic diffusion breathing wallboard is installed with an upper buckle lock, and the bottom side end of the acoustic diffusion breathing wallboard is installed with a lower buckle lock. The top of the acoustic diffusion breathing wallboard is locked to the upper hanging bar via the upper buckle lock, and the bottom of the acoustic diffusion breathing wallboard is locked to the lower hanging bar via the lower buckle lock. During actual installation, the acoustic diffusion breathing wallboard only needs to be hooked to the upper hanging bar and the lower hanging bar via the upper buckle lock and the lower buckle lock respectively. The construction is very convenient, and the hook-type structure makes the acoustic diffusion breathing wallboard subsequently removable, which is convenient for maintenance and replacement.

[0010] Preferably, the upper buckle lock and the lower buckle lock have the same structure and both include a buckle lock bar, a base is provided at the bottom of the buckle lock bar, the hook is hinged in the base by a lower fixing screw, the locking hook is hinged to the hook by a locking hook fixing screw, a third spring limit screw and a fourth spring limit screw are provided on the hook, a second spring limit screw is provided on the base, the hook spring is sleeved on the lower fixing screw, and the left and right end edges of the hook spring extending outward are respectively in contact with the third spring limit screw and the second spring limit screw, the locking hook spring is sleeved on the locking hook fixing screw, and the left and right end edges of the locking hook spring extending outward are respectively in contact with the second spring limit screw and the fourth spring limit screw, and an upper limit slot block and a lower limit slot block are respectively provided at the upper and lower ends of the hook on the base. During actual installation, before the module is installed, the hook spring presses the hook into the lower limit slot, causing the locking hook to open and create a relaxed state. Once the module is properly installed, the hook is pressed into the upper limit slot, where the locking hook is pushed against the edge of the hook slot, creating a locked state. The installation process for the lower buckle lock is as follows: the wall panel hook slot is pressed down onto the hanging bar, then pushed toward the hanging bar. When the wall panel and the hanging bar are at right angles, the locking hook presses against the hanging bar, and the protruding small hook below locks the hanging bar securely, allowing the buckle lock to quickly and stably engage with the hanging bar, facilitating the rapid installation of the acoustic diffusion breathing wall panel.

[0011] Preferably, the left and right side ends of two adjacent filter housings are reinforced and connected by aluminum bars to enhance the connection strength between the two adjacent filter housings.

[0012] Preferably, the air duct is connected to the constant temperature fresh air system in the air conditioner to provide the breathing wall with air breathing power.

[0013] The beneficial effects of the acoustic diffusion breathing wall provided by the utility model are as follows: the acoustic diffusion breathing wall can improve both air quality and acoustic diffusion effects, has a simple structure and diverse functions, and the acoustic diffusion breathing wall panels adopt a modular design. During actual assembly, it only needs to connect the filter housings through modular connecting pipes, making production and installation very convenient. The filter base plate in the acoustic diffusion filter plate has an excellent filtering effect. The structural design of the diffusion fins facilitates the diffusion of sound indoors. In actual operation, when the external constant temperature fresh air system applies positive pressure to the air duct, air from the air duct enters the filter housing through the ventilation connecting pipe, is discharged from the surface of the acoustic diffusion filter plate, and is filtered by the filter base plate in the acoustic diffusion filter plate before providing fresh air to the room. When the external constant temperature fresh air system applies negative pressure to the air duct, the indoor air enters the filter housing through the acoustic diffusion filter plate and is discharged from the air duct through the relevant pipes. Throughout this process, the acoustic diffusion filter plate not only filters the air but also acoustically diffuses the sound indoors. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary persons in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment: A breathing wall with acoustic diffusion function.

[0023] Reference Figures 1 to 6As shown, a breathing wall with an acoustic diffusion function comprises: a hanger mounted on a rough wall 1, the hanger comprising an upper hanging bar 5 and a lower hanging bar 8 spaced side by side, the upper hanging bar 5 and the lower hanging bar 8 both being fixed to the rough wall 1 by angle codes to facilitate the subsequent installation of the acoustic diffusion breathing wall panel 2. An upper buckle 6 is installed on the top side end of the acoustic diffusion breathing wall panel 2, and a lower buckle 7 is installed on the bottom side end of the acoustic diffusion breathing wall panel 2. The top of the acoustic diffusion breathing wall panel 2 is locked to the upper hanging bar 5 by the upper buckle 6, and the bottom of the acoustic diffusion breathing wall panel 2 is locked to the lower hanging bar 8 by the lower buckle 7. During actual installation, the acoustic diffusion breathing wall panel 2 only needs to be hooked to the upper hanging bar 5 and the lower hanging bar 8 by the upper buckle 6 and the lower buckle 7 respectively. The construction is very convenient, and the hook-type structure is adopted, so that the acoustic diffusion breathing wall panel 2 can be disassembled later, which is convenient for maintenance and replacement.

[0024] Reference Figure 6 As shown, the upper lock buckle 6 has the same structure as the lower lock buckle 7, and both include a lock bar 611, which is fixed to the fixed aluminum bar 9 by an upper fixing screw 612. A base 610 is provided at the bottom of the lock bar 611, and the hook 64 is hinged in the base 610 by a lower fixing screw 68. The upper and lower ends of the hook 64 on the base 610 are respectively provided with an upper limit slot block 67 and a lower limit slot block 66, which are used to limit the maximum distance when the hook 64 moves up and down, respectively. The locking hook 61 is hinged to the hook 64 by a locking hook fixing screw 65. The hook 64 is provided with a third spring limiting screw 614 and a fourth spring limiting screw 615, and the base 610 is provided with a second spring limiting screw 613. The hook spring 69 is sleeved on the lower fixing screw 68, and the left and right ends of the hook spring 69 extending outward are respectively in contact with the third spring limiting screw 614 and the second spring limiting screw 613. The locking hook spring 62 is sleeved on the locking hook fixing screw 65, and the left and right ends of the locking hook spring 62 extending outward are respectively in contact with the second spring limiting screw 613 and the fourth spring limiting screw 615. During actual installation, before the acoustic diffusion breathing wall panel 2 is installed, due to the action of the hook spring 69, the hook 64 is pressed to the position of the lower limit slot block 66, and the locking hook 61 is opened, forming a relaxed state; when the acoustic diffusion breathing wall panel 2 is properly installed, the hook 64 is pressed to the upper limit slot block 67, and the locking hook 61 is pushed by the upper limit slot block 67 and pressed against the edge of the hook slot 63, forming a locked state. In this embodiment, the installation process of the upper lock 6 and the lower lock 7 is as follows: the wall panel hook slot is pressed downward onto the hanging strip, and then pushed in the direction of the hanging strip. When the wall panel is at right angles to the hanging strip, the locking hook 61 is pressed against the hanging strip, and the small hook protruding below clamps the hanging strip and tightens it, so that the lock and the hanging strip are quickly and stably engaged, so as to facilitate the rapid installation of the acoustic diffusion breathing wall panel 2.

[0025] The acoustic diffusion breathing wall panel 2 adopts a modular design and includes a filter housing 21. The surface of the filter housing 21 is mounted with an acoustic diffusion filter plate 22. The acoustic diffusion filter plate 22 includes a filter base plate 221 and diffusion fins 222. The filter base plate 221 is fixed to the filter housing 21, and the diffusion fins 222 are mounted on the filter base plate 221 and arranged perpendicularly to the filter base plate 221. The filter base plate 221 is formed by using gypsum with added diatomaceous earth and zinc oxide to form a microporous structure of 50-100 nanometers. It can filter out PM2.5 and PM1.0 dust, as well as viruses and bacteria floating in the air, and particles larger than 100 nanometers. Zinc oxide can kill bacteria and viruses attached to the surface, having a sterilizing and mildew-proofing effect. The diffusion fins 222 are made of solid wood and are arranged perpendicular to the filter base plate 221, which is conducive to the diffusion of indoor sound.

[0026] The filter housing 21 is provided with vents 26 at both ends. The vents 26 of two adjacent filter housings 21 are connected by a hollow modular connecting pipe 25. The bottom vent of the bottommost filter housing 21 is installed with a connecting air nozzle 23, which is connected to the air duct 4 via a ventilation connecting pipe 3. The top vent of the topmost filter housing 21 is installed with a vent cover 24 to seal the top vent 26. Screw holes 27 are provided on the left and right side ends of the two adjacent filter housings 21, and the left and right side ends of the two adjacent filter housings 21 are reinforced and connected by aluminum bars 9 to enhance the connection strength between the two adjacent filter housings 21.

[0027] An air duct 4 is installed at the bottom of the rough wall 1. The acoustic diffusion breathing wall panel 2 is connected to the air duct 4 through a ventilation connecting pipe 3. The air duct 4 is connected to the constant temperature fresh air system in the air conditioner to provide air breathing power for the breathing wall.

[0028] The breathing wall with acoustic diffusion function adopts a hanging buckle structure, which is easy to construct, has high installation efficiency, and is simple in structure, and has low production and installation costs. During actual installation, it is only necessary to fix the upper hanging bar 5 and the lower hanging bar 8 on the rough wall 1 by the angle code, and then the modular acoustic diffusion breathing wallboard 2 is locked on the upper hanging bar 5 and the lower hanging bar 8 by the upper buckle lock 6 and the lower buckle lock 7, thereby significantly improving the installation efficiency of the acoustic diffusion breathing wallboard 2, and in subsequent maintenance, the overall disassembly of the acoustic diffusion breathing wallboard 2 can be achieved, and the recycling of the acoustic diffusion breathing wallboard 2 is realized, which is green and environmentally friendly. The acoustic diffusion breathing wallboard 2 adopts a modular design, and it is only necessary to connect the filter housings 21 by the module connecting pipe 25 during actual assembly, and it is very convenient to produce and install. This breathing wall with acoustic diffusion function includes two working modes: exhalation and inhalation. When the constant temperature fresh air system applies positive pressure to the air duct 4, air enters the filter housing 21 from the air duct 4 through the ventilation connecting pipe 3 and the connecting pipe of the ventilation module, and is discharged from the surface of the acoustic diffusion filter plate 22. This is an exhalation process. When the constant temperature fresh air system applies negative pressure to the air duct 4, air enters the filter housing 21 from the acoustic diffusion filter plate 22 and is discharged from the air duct 4 through the relevant pipeline. This is an inhalation process. Since the filter bottom plate 221 in the acoustic diffusion filter plate 22 is formed by plaster with diatomaceous earth and zinc oxide molded to form a microporous structure of 50-100 nanometers, it can filter out PM2.5, PM1.0 dust, viruses, bacteria and other particles larger than 100 nanometers floating in the air. Zinc oxide can kill bacteria and viruses attached to the surface and has a bactericidal and mildew-proof effect. The diffusion fins 222 are made of solid wood and are arranged perpendicular to the filter bottom plate 221, which is conducive to the diffusion of indoor sound, thereby ensuring that the breathing wall can not only filter the air, but also acoustically diffuse the indoor sound.

[0029] The above description is only a preferred embodiment of the present invention, but the present invention should not be limited to the contents disclosed in the embodiment and the drawings. Therefore, any equivalent or modification completed without departing from the spirit disclosed in the present invention shall fall within the scope of protection of the present invention.
