[0048] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.
[0049] The embodiment of the present application discloses a soundproof ventilation window.
[0050] Reference Figure 1 , Figure 2 and Figure 3 A soundproof ventilation window comprises a ventilation chamber 10, a soundproof shell 20, a central shaft 30, a soundproof fan blade 40, an air supply fan blade 50, a driving member 60, a diverter plate 70 and a window frame 80, wherein a vent 81 is provided on one side of the window frame 80; the ventilation chamber 10 is arranged on the side wall of the window frame 80, and the ventilation chamber 10 is provided with an air inlet 11 and an air outlet 12, and the air outlet 12 is communicated with the vent 81; the soundproof shell 20 is accommodated in the ventilation chamber 10, and the soundproof shell 20 comprises a fan blade cover 21; the central shaft 30 is accommodated in the soundproof shell 20, and the central shaft 30 is abutted against two ends of the soundproof shell 20; the soundproof fan blade 40 is connected to the fan blade cover 21 and the side of the central shaft 30; the fan blade cover 21 is sleeved on the soundproof fan blade 40; and the fan blade cover 21 abuts against the side wall of the ventilation chamber 10.
[0051] A ventilation louver is provided at the vent 81 of the soundproof window frame 80, and the ventilation louver is provided with a vent 81. When wind enters the ventilation chamber 10 from the air inlet 11 of the ventilation chamber 10, the central shaft 30 rotates to drive the soundproof fan blade 40 to rotate, and the fan blade rotates to accelerate the flow of wind, so that the wind entering the room from the vent 81 is larger. The end of the soundproof shell 20 is connected to the end of the ventilation chamber 10 to prevent sound from leaking from the end of the soundproof shell 20. The fan cover 21 abuts against the side wall of the ventilation chamber 10 to prevent sound from leaking from the gap between the fan cover 21 and the ventilation chamber 10 when the soundproof fan blade 40 accelerates the wind flow. The soundproof fan blade 40 connects the fan cover 21 and the central shaft 30 to prevent sound from leaking from the gap between the fan cover 21 and the central shaft 30. When wind enters from one side of the ventilation chamber 10, the sound is restricted to the maximum extent possible, and the rotation of the soundproof fan blade 40 improves the ventilation and air supply capacity. It solves the problem that there is noise when the window is opened and the indoor ventilation is affected by closing the window.
[0052] Reference Figure 3 , at least two sound insulation blades 40 are respectively in contact with the inner wall of the ventilation chamber 10. The sound insulation blades 40 are set to be concave, and the sound insulation blades 40 rotate in the direction of the concave of the blades. The rotation of the blades accelerates the flow of wind. The sound insulation blades 40 can be provided with eight pieces, and the eight pieces are symmetrically arranged. The sound insulation blades 40 are connected to the sound insulation shell 20 and the central rotating shaft 30. When the sound insulation blades 40 rotate, two of the eight sound insulation blades 40 are located near the upper wall of the ventilation chamber 10, and two are located near the lower wall of the ventilation chamber 10. There are always at least two sound insulation blades 40 in the upper and lower parts respectively in contact with the sound insulation shell 20 at the inner wall of the ventilation chamber 10. The two layers of sound insulation blades 40 form a sound insulation cavity, which has a good sound insulation effect on the sound in the entire ventilation chamber 10.
[0053] Reference Figure 3 The abutment between the fan blade cover 21 and the ventilation chamber 10 is provided with wear-resistant material, and the fan blade cover 21 is correspondingly arranged with eight sound insulation fan blades 40, and the fan blade cover 21 is fixedly connected with the sound insulation fan blades 40. When the sound insulation shell 20 rotates relative to the ventilation chamber 10, at least two of the eight sound insulation shells 20 always abut against the upper wall of the ventilation chamber 10, and two are located to abut against the lower wall of the ventilation chamber 10. There are always at least two upper and lower sound insulation shells 20 respectively abutting against the ventilation chamber 10, so that the two layers of sound insulation fan blades 40 form a sound insulation cavity. The fan blade cover 21 rotates relative to the ventilation chamber 10, and the wear-resistant material on the top of the fan blade cover 21 reduces the wear of the contact part when the fan blade cover 21 rotates relative to the ventilation chamber 10.
[0054] Reference Figure 3The soundproof shell 20 also includes two soundproof tubes 22 arranged opposite to each other. The two soundproof tubes 22 are respectively located at the two ends of the ventilation chamber 10 and are coaxially fixedly connected to the central shaft 30. The soundproof fan blade 40 is installed between the two soundproof tubes 22, and the two ends of the soundproof fan blade 40 are respectively fixedly connected to the two soundproof tubes 22. A plurality of air supply fan blades 50 are also arranged between two adjacent soundproof fan blades 40, and the air supply fan blades 50 are arranged between the two soundproof tubes 22, and the air supply fan blades 50 are fixedly connected to the soundproof tubes 22. The air supply fan blades 50 are installed at the end of the soundproof shell 20, and the air supply fan blades 50 and the soundproof fan blades 40 are both arranged between the two soundproof tubes 22 and fixedly connected to the soundproof tubes 22, which can prevent sound from leaking out of the gap between the fan blades and the ventilation chamber 10. Multiple air supply fan blades 50 are inserted between the soundproof fan blades 40, which can accelerate the flow of wind and make the wind discharged from the vent 81 larger.
[0055] Reference Figure 3 , Figure 4 and Figure 5 The sound insulation tube 22 includes a circular plate 221 and a cylinder 222 coaxially fixedly connected to the circular plate 221 , the sound insulation shell 20 is coaxially rotatably connected to the ventilation bin 10 , the end of the fan cover 21 is detachably connected to the sound insulation shell 20 , and the cylinder 222 is embedded with the sound insulation fan blade 40 .
[0056] The fan blade cover 21 on the sound insulation shell 20 is detachable. Since the rotation speed of the sound insulation shell 20 relative to the ventilation chamber 10 is not slow, the wear-resistant material on the top of the fan blade cover 21 may be damaged. At this time, it is only necessary to remove the fan blade cover 21 from the sound insulation shell 20 and separate it from the sound insulation fan blade 40 to replace the fan blade cover 21, and there is no need to replace the entire sound insulation fan blade 40. After replacing a new fan blade cover 21 or a new wear-resistant material, the fan blade cover 21 is set on the sound insulation fan blade 40 and then snapped into the sound insulation shell 20 to complete the replacement of the wear-resistant material.
[0057] The circular plate 221 is fixedly connected to the end of the sound insulation shell 20 , and the cylinder 222 connects the circular plate 221 and the fan blade cover 21 . The cylinder 222 is sleeved and embedded outside the sound insulation fan blade 40 to prevent sound from leaking from the gap between the sound insulation shell 20 and the sound insulation fan blade 40 .
[0058] Reference Figure 4 and Figure 5 A rotating groove 2211 is provided at the end of the circular plate 221, and a protrusion 13 is provided in the ventilation chamber 10, and the rotating groove 2211 is rotatably connected to the protrusion 13. A rotating groove 2211 is provided at the end of the sound insulation shell 20, and the sound insulation shell 20 is rotatably connected to the protrusion 13 of the ventilation chamber 10 through the groove. The sound insulation shell 20 can rotate relative to the ventilation chamber 10, and at the same time, the groove and the protrusion 13 are arranged back and forth to isolate the sound as much as possible, and prevent the sound from leaking from the gap between the sound insulation shell 20 and the end of the ventilation chamber 10.
[0059] Reference Figure 3 and Figure 5 The driving member 60 passes through the protrusion 13 and the rotation groove 2211, and is connected to the central rotating shaft 30 and the sound insulation shell 20. The driving member 60 may be a motor 61, and the output shaft of the motor 61 is connected to the central rotating shaft 30 and the sound insulation shell 20, driving the central rotating shaft 30 and the sound insulation shell 20 to rotate, and the rotation of the central rotating shaft 30 and the sound insulation shell 20 drives the sound insulation blade 40 and the air supply blade 50 to rotate, which can accelerate the flow of wind and make the wind discharged from the vent 81 stronger.
[0060] Reference Figure 3 and Figure 6 The diverter plate 70 is arranged between the vent 81 and the ventilation chamber 10, and a through hole 71 is provided on the diverter plate 70, and the through holes 71 are distributed so that the aperture increases from the two sides to the middle. The ventilation louvers are arranged on the upper and lower sides and the left and right sides of the soundproof window. The sound is shielded after passing through the ventilation chamber 10, and the wind forms a chaotic wind with a large wind speed after passing through the ventilation chamber 10, and flows out from the upper and lower sides of the soundproof window. The diverter plate 70 diverts the wind flowing out from the upper and lower sides of the soundproof window. The diverter plate 70 is arranged on the side wall of the soundproof shell 20. A small part of the wind enters the ventilation louvers on the upper and lower sides of the soundproof window from the upper and lower sides of the diverter plate 70, and a large part of the wind flows to the middle of the soundproof window under the guidance of the guide plate. The aperture of the through hole 71 increases from the two sides to the middle, so that when the wind flows to the middle along the guide plate, there is still wind flowing out from the middle vent 81, so that the air volume flowing out of the vents 81 on all four sides remains roughly uniform.
[0061] The implementation principle of a soundproof ventilation window in this embodiment is as follows: wind enters the ventilation chamber 10 from one side of the ventilation chamber 10, and in the ventilation chamber 10, the central rotating shaft 30 and the soundproof shell 20 rotate to drive the soundproof fan blades 40 and the air supply fan blades 50 to rotate. The rotation of the fan blades accelerates the flow of wind, making the wind entering the room from the vent 81 stronger.
[0062] The end of the sound insulation shell 20 is rotatably connected to the end of the ventilation chamber 10 through the protrusion 13 and the rotation groove 2211 to prevent sound from leaking from the end of the sound insulation shell 20. The fan cover 21 is abutted against the upper and lower side walls of the ventilation chamber 10 through wear-resistant materials to prevent sound from leaking from the gap between the fan cover 21 and the ventilation chamber 10. The sound insulation fan blade 40 connects the fan cover 21 and the central shaft 30 to prevent sound from leaking from the gap between the fan cover 21 and the central shaft 30.
[0063] When wind enters from one side of the ventilation chamber 10, the sound is limited to the greatest extent possible, and the rotation of the sound insulation blades 40 and the air supply blades 50 improves the ventilation and air supply capacity, while the setting of the guide plate makes the wind flow more uniform when entering the room, thus solving the problem that there is noise when the window is open and the indoor ventilation is affected when the window is closed.
[0064] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
