Abstract
Description
Technical Field
[0001] This utility model relates to the field of soundproof window technology, and in particular to a low wind resistance ventilation soundproof window. Background Technology
[0002] With the acceleration of urbanization, environmental noise pollution such as traffic noise and industrial noise is becoming increasingly serious, severely affecting the quality of life of residents. Traditional windows usually use single or double-glazed structures, which have a certain sound insulation effect, but when ventilation is needed, opening the windows will cause a large amount of noise to enter the room, failing to meet both ventilation and sound insulation requirements.
[0003] In existing technologies, some ventilated soundproof windows reduce noise by incorporating sound-absorbing channels or materials, but these suffer from problems such as complex structures, high costs, or low ventilation efficiency. For example, some designs use multi-layer perforated panels or labyrinth structures, which can improve sound insulation performance but result in high ventilation resistance and affect airflow; other solutions rely on electrically powered ventilation equipment, increasing energy consumption and maintenance costs. Furthermore, existing soundproof windows often struggle to balance high sound insulation with convenience, limiting their widespread application. Utility Model Content
[0004] The main purpose of this utility model is to provide a low wind resistance ventilation and sound insulation window, which aims to make the sound insulation window structure simple and have good sound insulation and ventilation performance.
[0005] To achieve the above objectives, this utility model proposes a low-wind-resistance ventilation and soundproof window, which includes a window frame, a window through hole, a first window structure on one side of the window through hole, and a second window structure on the other side. The first window structure and the second window structure are sandwiched together to form a ventilation cavity.
[0006] The window frame is symmetrically provided with a sound insulation structure along the vertical direction. The sound insulation structure passes through the ventilation cavity. The sound insulation structure has a sound insulation cavity opposite to the ventilation cavity. The end face of the sound insulation structure facing the sound insulation cavity has multiple sound-absorbing holes. The sound insulation structure is provided with sound insulation material facing the sound-absorbing holes.
[0007] In one embodiment of this application, the sound insulation structure includes a first sound insulation part and a second sound insulation part. The first sound insulation part is connected to the second window structure and has a guide part protruding towards the first window structure. The second sound insulation part is connected to the first window structure and has a guide groove recessed relative to the guide part. The sound insulation cavity is located between the guide part and the guide groove.
[0008] The end face of the second sound insulation part facing away from the guide groove has a buffer part protruding from the window frame.
[0009] In one embodiment of this application, the window frame has an encapsulation part at the end opposite to the sound insulation cavity of the first sound insulation part, the guide part and the encapsulation part surround to form an installation cavity, the installation cavity is disposed towards the ventilation cavity, and a buffer structure is provided inside the installation cavity.
[0010] In one embodiment of this application, the first window structure has an air inlet window at one end relative to the ventilation cavity, and the second window structure has an air outlet window at the other end relative to the ventilation cavity. The air inlet window and the air outlet window are rotatably connected to the window structure.
[0011] In one embodiment of this application, the window frame is provided with an adjustment cavity relative to the air inlet window and the air outlet window, the air inlet window and the air outlet window are both provided through the adjustment cavity, and a transmission structure is provided in the adjustment cavity;
[0012] The transmission structure includes an adjusting gear and a transmission shaft. There are at least two adjusting gears, which are respectively connected to the air inlet and air outlet. The two ends of the transmission shaft are provided with transmission gears relative to the adjusting gears, and the adjusting gears are driven to the transmission gears.
[0013] In one embodiment of this application, the second window structure is provided with an adjustment window relative to the air inlet window, and the adjustment window is rotatably connected to the adjustment cavity.
[0014] By adopting the above technical solution, this utility model has the following advantages:
[0015] 1. Low-resistance ventilation and soundproof windows can be functionally and structurally divided into a window frame that supports the entire window body. The window frame has window openings for installing glass and other structures. The glass structure installed on the window frame includes a first window structure and a second window structure. The first window structure and the second window structure can serve as the inner and outer windows of the ventilation and soundproof window. There is a ventilation cavity between the inner and outer windows that can physically insulate sound. When the inner and outer windows are open, the entire window can be used for ventilation. When closed, it can be used for sound insulation. The whole structure is simple and has a good sound insulation effect.
[0016] 2. To ensure that the ventilated and soundproof window can isolate most of the external sound while allowing ventilation, a soundproof structure is installed within the window opening. This structure contains a soundproof cavity connected to the ventilation chamber. The soundproof structure is covered with sound-absorbing materials such as sound-absorbing cotton. Multiple sound-absorbing holes are arrayed on both sides of the soundproof cavity. When ventilation and soundproofing are required, the windows diagonally positioned in the first and second window structures are opened, connecting the ventilation cavity, soundproof cavity, and the outside. Airflow enters the soundproof cavity along one side of the ventilation cavity. The sound-absorbing holes capture sound and guide some of it towards the soundproof material (such as sound-absorbing cotton), causing sound to lose some energy as it passes through a hole. The numerous sound-absorbing holes arrayed on both sides of the soundproof cavity effectively improve sound insulation without compromising ventilation performance, thus enhancing the user experience.

[0023] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0025] Reference Figures 1 to 3 To achieve the above objectives, this utility model proposes a low wind resistance ventilation and sound insulation window, which includes a window frame 1, a window through hole 4, a first window structure 41 on one side of the window through hole 4, and a second window structure 43 on the other side. The first window structure 41 and the second window structure 43 are sandwiched together to form a ventilation cavity.
[0026] The window frame 1 is symmetrically provided with a sound insulation structure 5 along the vertical direction. The sound insulation structure 5 passes through the ventilation cavity. The sound insulation structure 5 is provided with a sound insulation cavity 52 opposite to the ventilation cavity. The end face of the sound insulation structure 5 facing the sound insulation cavity 52 has a plurality of sound-absorbing holes 51. The sound insulation material is provided inside the sound insulation structure 5 facing the sound-absorbing holes 51.
[0027] The low-resistance ventilation and soundproof window can be functionally and structurally divided into a window frame 1 that supports the entire window body. The window frame 1 has a window opening 4 for installing glass and other structures. The glass structure installed on the window frame 1 includes a first window structure 41 and a second window structure 43. The first window structure 41 and the second window structure 43 can serve as the inner and outer windows of the ventilation and soundproof window. There is a ventilation cavity between the inner and outer windows that can physically insulate sound. When the inner and outer windows are opened, the entire window can be used for ventilation. When closed, it can be used for sound insulation. The whole structure is simple and has a good sound insulation effect.
[0028] To ensure that the ventilated and soundproof window can block most of the external sound while ventilating, a sound insulation structure 5 is provided inside the window opening 4. The sound insulation structure 5 has a sound insulation cavity 52 connected to the ventilation cavity. The sound insulation structure 5 is covered with sound insulation materials such as sound-absorbing cotton. The sound insulation structure 5 has multiple sound-absorbing holes 51 arrayed on both sides of the sound insulation cavity 52. When ventilation and sound insulation are required, the windows of the first window structure 41 and the second window structure 43, which are diagonally arranged, are opened, so that the ventilation cavity, the sound insulation cavity 52 and the outside are connected. The wind enters the sound insulation cavity 52 along one side of the ventilation cavity. The sound-absorbing holes 51 can be used to capture sound and guide some of the sound towards the sound insulation material (sound-absorbing material, such as sound-absorbing cotton). When the sound passes through a sound-absorbing hole 51, a certain amount of energy is lost. The large number of sound-absorbing holes 51 arrayed on both sides of the sound insulation cavity 52 can effectively improve the sound insulation effect while keeping the overall structure simple, without affecting the ventilation performance, and can effectively improve the user experience.
[0029] See also Figures 1 to 3The sound insulation structure 5 includes a first sound insulation part 53 and a second sound insulation part 55. The first sound insulation part 53 is connected to the second window structure 43 and has a guide part 54 protruding towards the first window structure 41. The second sound insulation part 55 is connected to the first window structure 41 and has a guide groove 56 recessed relative to the guide part 54. The sound insulation cavity 52 is located between the guide part 54 and the guide groove 56.
[0030] The second sound insulation part 55 has a buffer part protruding from the end face opposite to the guide groove 56 and relative to the window frame 1.
[0031] In one embodiment of this application, the first window structure 41 is an outdoor window, the second window structure 43 is an indoor window, the first sound insulation part 53 of the sound insulation structure 5 is connected to the second window structure 43 and has a guide part 54 protruding towards the first window structure 41, while the second sound insulation part 55 has a guide groove 56 relative to the guide part 54. Through the above structure, the increased air intake and sound insulation cavity 52 can improve the sound insulation effect while minimizing the impact on ventilation performance.
[0032] See also Figure 3 The window frame 1 has a sealing part 11 at the end opposite to the first sound insulation part 53 and the sound insulation cavity 52. The guide part 54 and the sealing part 11 enclose and form a mounting cavity 12. The mounting cavity 12 is set towards the ventilation cavity and has a buffer structure inside.
[0033] The first sound insulation part 53 is connected to the interior. The window frame 1 is provided with a sealing part 11 relative to the first sound insulation part 53. The mounting cavity 12 enclosed by the sealing part 11 and the guide part 54 is used to set up a buffer structure. The buffer structure can be made entirely of sound insulation material. Sound insulation materials such as sound insulation cotton have good sound insulation effect and a certain buffering capacity. Because the ventilation cavity is connected to the guide part 54, a larger amount of buffer structure can be set in the mounting cavity 12, which can buffer the wind when it enters. The vibration generated by the wind hitting the guide part 54 can be absorbed by the buffer structure. It can effectively insulate sound while making the structure of the soundproof window itself stronger and effectively improving the service life of the window.
[0034] See also Figure 3 The first window structure 41 has an air inlet window 42 at one end relative to the ventilation cavity, and the second window structure 43 has an air outlet window 44 at the other end relative to the ventilation cavity. The air inlet window 42 and the air outlet window 44 are rotatably connected to the window structure.
[0035] The air inlet window 42 and the air outlet window 44 are located diagonally opposite the window opening 4, which can maximize the sound insulation effect of the sound insulation cavity 52.
[0036] See also Figures 1 to 2 The window frame 1 is provided with an adjustment cavity 2 relative to the air inlet window 42 and the air outlet window 44. The air inlet window 42 and the air outlet window 44 are both passed through the adjustment cavity 2. The adjustment cavity 2 is provided with a transmission structure 3.
[0037] The transmission structure 3 includes an adjusting gear and a transmission shaft. There are at least two adjusting gears, which are respectively connected to the air inlet window 42 and the air outlet window 44. The two ends of the transmission shaft are equipped with transmission gears relative to the adjusting gears, and the adjusting gears are driven to the transmission gears.
[0038] The window frame 1 is provided with an adjustment cavity 2. Two adjustment cavities 2 can be provided. Each of the two adjustment cavities 2 is provided with a set of transmission structures 3. The two transmission structures 3 are connected to the top and bottom of the window. The adjustment gear can rotate with the window. Both the adjustment gear and the transmission gear are bevel gears. They are connected to each other through two vertical bevel gears and through a transmission shaft. This allows the user to open the outer window when opening the inner window, which can effectively improve the user experience.
[0039] See also Figure 3 The second window structure 43 is provided with an adjustment window relative to the air inlet window 42, and the adjustment window is rotatably connected to the adjustment cavity 2.
[0040] An adjustable window can also be installed at the inner window. When the air inlet window 42 cannot be fully opened according to the user's needs, the user can directly adjust the air inlet window 42 by opening the adjustable window, which can effectively improve the user experience.
