The term "and / or" used in the specification of the present utility model includes any and all combinations of one or more related listed items.

[0032] Combine the following Figure 1-Figure 4 The utility model describes a ventilation sound insulation structure and a sound insulation window.

[0033] like Figure 1 As shown, in one embodiment, a ventilation and sound insulation structure includes a housing 100 , a fan 200 , an air guide plate 300 , a first sound insulation plate 400 , and a second sound insulation plate 500 .

[0034] The housing 100 has an air inlet 110 on one side and an air outlet 120 on the other side. The air inlet 110 is located outdoors, and the air outlet 120 is located indoors.

[0035] The fan 200 is installed in the housing 100 , and the fan 200 is a cross-flow fan.

[0036] The air guide plate 300 is fixed in the housing 100 .

[0037] The first sound insulation board 400 is fixed in the housing 100 , and the first sound insulation board 400 has a first through hole 410 .

[0038] The second sound insulation board 500 is fixed in the housing 100 . The second sound insulation board 500 and the first sound insulation board 400 are parallel to each other, and the second sound insulation board 500 has a second through hole 510 .

[0039] The first through holes 410 and the second through holes 510 are arranged alternately, and a fiber layer 600 is disposed between the first sound insulation board 400 and the second sound insulation board 500 .

[0040] When the ventilation and sound insulation structure is in use, the housing 100 is installed on the window, and then the fan 200 is able to control the exchange of indoor and outdoor airflows, thereby realizing the circulation of indoor airflow. The first through hole 410, the second through hole 510 and the gaps between the fibers inside the fiber layer 600 provide high porosity and specific surface area, which are conducive to the absorption of sound waves. At the same time, the fiber layer 600 can reduce the vibration amplitude of the sound waves and further reduce the sound intensity. The mutual cooperation between the first sound insulation board 400, the second sound insulation board 500 and the fiber layer 600 facilitates the reduction of the external urban noise pollution that affects the normal life and mental health of people indoors.

[0041] like Figure 3 As shown, in one embodiment, a plurality of first sound insulation columns 420 are fixedly connected between the first sound insulation board 400 and the wind guide board 300 .

[0042] Specifically, a plurality of second sound insulation columns 430 are fixedly connected between the first sound insulation board 400 and the wind guide plate 300 . The second sound insulation columns 430 are staggered with the first sound insulation columns 420 . The length of the first sound insulation columns 420 is greater than that of the second sound insulation columns 430 . The second sound insulation columns 430 are parallel to each other.

[0043] It should be additionally explained that a second groove 440 is formed on the outer wall of the first sound insulation column 420 .

[0044] When the sound waves of external noise are transmitted between the first sound insulation board 400 and the second sound insulation column 430, the propagation direction of the sound waves is first changed by the staggered first sound insulation columns 420 and the second sound insulation columns 430, and the propagation distance of the sound waves in the closed space is reduced by reflection and scattering, thereby reducing the intensity of echo and reverberation. The cavity formed between the first sound insulation columns 420 and the second sound insulation columns 430 of different lengths and the second groove 440 facilitates the absorption of the sound waves and converts them into heat energy or other forms of energy. At the same time, the sound waves resonate after entering the second groove 440, which facilitates the conversion of sound into heat energy and enhances the sound absorption effect.

[0045] like Figure 4 As shown, in one embodiment, the inner wall of the air guide plate 300 is fixedly connected with a first elastic net 310 and a second elastic net 320, the first elastic net 310 and the second elastic net 320 are parallel to each other, and the grids in the first elastic net 310 and the second elastic net 320 are staggered.

[0046] The first elastic net 310 and the second elastic net 320 arranged in a staggered grid are convenient for buffering the airflow entering the room, reducing the noise caused by the collision between the airflow and the ventilation and sound insulation structure under the action of a large impact force, and at the same time, it is convenient to rebound the external noise pollution to a certain extent.

[0047] like Figure 2As shown, in one embodiment, a filter screen 700 is fixedly connected to the inner wall of the housing 100, and the filter screen 700 is parallel to the first sound insulation board 400, so as to filter the airflow entering the room, thereby facilitating the provision of clean airflow.

[0048] In this embodiment, the inner wall of the shell 100 is provided with a slot 130 which is interference fit with the filter 700, the surface of the filter 700 is fixedly connected with an extension plate 710, the surface of the shell 100 is provided with a first groove 140 which is interference fit with the extension plate 710, and the extension plate 710 and the shell 100 are connected by bolts.

[0049] In this embodiment, a support frame 150 is fixedly connected to the side wall of the housing 100 , and a mounting hole 160 is formed on the support frame 150 .

[0050] Since the filter 700 is prone to dust accumulation during long-term use, the housing 100 needs to be removed from the window after being used for a period of time, and then the filter 700 needs to be disassembled and cleaned, thereby improving the filtering effect of the filter 700.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
