Description

Technical Field

[0001] The invention relates to the technical field of building structure windows, in particular to a ventilation and sound-absorbing window with a membrane plate resonance structure. Background Art

[0002] In recent years, urban traffic has developed rapidly, and the traffic noise pollution caused by it has become increasingly serious. At the same time, good indoor ventilation is a necessary requirement for daily life. For this reason, ventilation and soundproofing window technology has become a common indoor noise reduction measure for buildings in noise pollution areas. Generally, ventilation and soundproofing windows can be divided into two types according to their ventilation characteristics: mechanical ventilation and natural ventilation.

[0003] The well-known industrial and civil ordinary windows have lighting, ventilation and heat preservation properties, but the sound insulation effect is poor, especially when the windows are opened for ventilation, they have no sound insulation effect. Outdoor environmental noise can directly enter the room and cause indoor noise pollution. When there is a high noise source indoors, it will also directly radiate to the outdoor environment and pollute the environment. In addition, the current windows are set to double-layer. When opening, the user needs to open the inner window first, and then manually open the outer window, which is very inconvenient. Summary of the invention

[0037] Furthermore, a connecting piece 205 is provided between the slip ring 202b and the rotating ring 202c, and the connecting piece 205 is used to connect the slip ring 202b with the rotating ring 202c. In the present embodiment, the connecting piece 205 includes a clamping block 205a provided on the outer wall of the slip ring 202b. There are two clamping blocks 205a, which are provided along the axial direction of the slip ring 202b. Then, a matching groove 205b matching with the clamping block 205a is provided on each rotating ring 202c, and the matching grooves 205b are all connected outwardly, so that after the slip ring 202b slides, the clamping block 205a can be inserted into the matching groove 205b.

[0038] Furthermore, in order to facilitate the operator to drive the slip ring 202b to slide, so that the slip ring 202b is connected to the upper rotating ring 202c and the lower rotating ring 202c respectively, a pull rod 205c is also fixed on the slip ring 202b, and the pull rod 205c is arranged in the horizontal direction, and then the pull rod 205c extends outward from the window frame 101, and a sliding hole for the pull rod 205c to move in the vertical direction is also opened on the window frame 101, and the sliding hole is connected to the window frame 101 outward, and then a first clamping hole 206 and a second clamping hole 207 are also opened on the window frame 101, the first clamping hole 206 is connected to the upper end of the sliding hole, and the second clamping hole 207 is connected to the lower end of the sliding hole.

When it is necessary to open the first outer rotating window 102a, it is only necessary to move the pull rod 205c downward so that the slide rod is connected to the rotating ring 202c at the lower end. At this time, the operator can open the second inner rotating window 103b. Utilizing this structure, the operator only needs to control the inner rotating window to open the corresponding outer rotating window, and the opened window will form a silencer passage, which cooperates with the silencer assembly 300 to achieve silencer.

[0042] Example 3

[0043] Reference Figure 2 This embodiment is different from the above embodiments in that: the sound-absorbing window 104 includes an outer window 301 arranged on the outside of the window frame 101 and an inner window 302 arranged on the inside of the window frame 101, the sound-absorbing component 300 includes a thin plate 303 arranged inside the sound-absorbing window 104 and an elastic membrane 304 arranged between the thin plate 303 and the sound-absorbing window 104, and the elastic membrane 304 divides the inside of the sound-absorbing window 104 into a thin film resonance cavity, wherein the film thickness is 0.01mm-0.1mm, and the thickness of the thin plate 303 is 1mm-5mm.

[0044] Furthermore, the soundproof window 104 includes an outer window 301 arranged near the outer side of the window frame 101 and an inner window 302 arranged near the inner side of the window frame 101. Both the inner window 302 and the outer window 301 cannot be opened. The distance between the inner window 302 and the outer window 301 is 50mm to 150mm. Sound-absorbing materials are pasted around the middle cavity. The sound-absorbing materials are sound-absorbing felt, and the perforated plate is pressed externally. The perforated plate is made of aluminum plate or aluminum-plastic plate, and the perforation rate is 3% to 10%. The window sashes are all made of double-layer glass, with a glass thickness of 3 to 8mm. The thickness of the double-layer glass is different. The outer glass is 2mm thicker than the inner glass. The inner and outer glass are not installed in parallel. The outer glass is inclined by 3° to 5°. The glass and the window frame 101 are sealed with rubber strips or sealants.

[0045] And the silencer component 300 is arranged between the inner window 302 and the outer window 301. In the present embodiment, the silencer component 300 includes a thin plate 303, which is a transparent plate made of polyethylene or polyvinyl chloride with high transparency. The thickness of the thin plate 303 is between 1 mm and 5 mm. The thin plate 303 is arranged parallel to the inner window 302 or the outer window 301. The four sides of the thin plate 303 are fixed and sealed to the four sides of the inner window 302 or the outer window 301, thereby forming a thin film resonance cavity between the thin plate 303 and the inner window 302 or the outer window 301. An elastic film 304 is also arranged on the thin plate 303. The elastic film 304 is elastic, made of polyethylene or polyvinyl chloride with high transparency, and the thickness of the film is between 0.01 mm and 0.1 mm.

[0046] Specifically, it is worth noting that in the present invention, only when the first outward-swinging window 102a and the second inward-swinging window 103b are opened or the second outward-swinging window 102b and the first inward-swinging window 103a are opened, the external sound passes through the ventilation duct 105 and the sound-absorbing window 104, ventilation is carried out and sound absorption is achieved at the same time, and after the outward-opening window 102 and the inward-opening window 103 are closed together, only the sealing sound insulation operation is performed.

[0047] The remaining structures are the same as those in Example 2.

[0048] The specific implementation principle of this embodiment is as follows: when the window is in a fully closed state, due to the sound insulation of the double-layer glass, the membrane plate structure and the additional sound absorption effect of the intermediate air layer, the indoor and outdoor propagation paths of noise can be effectively blocked, and the average sound insulation of ordinary windows is increased by 10dB to 20dB. During ventilation, since the left and right window sashes in the lower area can be opened inward and outward respectively, such as opening the outer sash of the left window sash in the lower area outward and the inner sash of the right window sash inward, the air inside and outside can be exchanged through the cavity between the middle window sashes. Conversely, if the inner sash of the left window sash is opened inward and the outer sash of the right window sash is opened outward, the purpose of indoor and outdoor air exchange can also be achieved. The sound insulation principle of the membrane and plate structure is that: the sound wave is incident on the elastic membrane 304 or the thin plate 303, and the elastic membrane 304 or the thin plate 303 vibrates under the excitation of the alternating pressure of the sound wave, and bends and deforms, resulting in friction loss inside the membrane and the plate, converting mechanical energy into heat energy. At the resonant frequency, the sound energy consumption is the largest. Since the noise is absorbed by the resonant cavity structure, the requirements of lighting and ventilation and effective sound insulation are achieved.
