[0027] Embodiment 1:

[0028] See also Figure 1-7 A soundproof and light-shielding curtain structure includes a soundproof and light-shielding curtain body 10, wherein the soundproof and light-shielding curtain body 10 includes a sound-absorbing layer 11, a light-shielding layer 12, and an air cushion layer 14 connected together from the outside to the inside, and an inflation nozzle 15 is provided on the air cushion layer 14. Through the above structure, soundproof and light-shielding are achieved.

[0029] The sound absorbing layer 11, the light shielding layer 12 and the air cushion layer 14 may be bonded together, may be sewn together, or may be connected together by a combination of bonding and sewing.

[0030] Specifically, the sound absorbing layer 11 is made of high molecular weight acrylic resin fiber cloth, which is a viscoelastic damping material that plays the role of reflecting and consuming sound wave energy.

[0031] Furthermore, the outer surface of the sound absorbing layer 11 adopts a waffle pattern with a strong three-dimensional effect. The waffle shape is used to make the surface of the fabric have a large difference in convexity and concavity, so that the equivalent sound path of the sound wave in the fabric is lengthened, the sound loss is increased, and the noise reduction effect is improved.

[0032] The light shielding layer 12 is made of light shielding cloth.

[0033] The air cushion layer 14 adopts an inflatable air cushion structure, and the thickness of the air cushion structure after inflation is about 15 mm. The air cushion layer 14 is a prior art, for example, the structure of an air mattress. The air cushion layer 14 has a strong air pressure shock absorption effect, which can consume the energy of sound waves, reduce its sound energy and sound pressure level, thereby further improving the sound insulation and noise reduction effect, and can improve the flatness of the interior of the soundproof blackout curtain body 10 when in use.

[0034] Furthermore, a sound insulation layer 13 is connected between the light shielding layer 12 and the air cushion layer 14. The sound insulation layer 13 is made of acrylic resin fiber cloth, which plays a role in secondary loss of sound wave energy, further reducing the noise entering the inner space of the bed curtain, achieving the purpose of silencing and reducing noise, and improving the sleeping environment quality of the inner space of the bed curtain.

[0035] Embodiment 2:

[0036] See also Figure 2 , a bed curtain 20, the bed curtain 20 is a cover structure with a hollow interior, a frame 30 is installed inside the bed curtain 20, the side and top of the bed curtain 20 adopt the above-mentioned sound insulation and noise reduction blackout curtain structure, the bottom of the bed curtain 20 is a non-slip cloth, the side of the bed curtain 20 is provided with an entrance and exit, the bed curtain 20 is provided with a door curtain 21 at the entrance and exit, one end of the door curtain 21 is connected to the bed curtain 20, and the other end surface is connected to the bed curtain 20 through a zipper 22. The bed curtain 20 is supported by the frame 30, the bottom of the bed curtain 20 is a non-slip cloth, and the surrounding and top sides adopt the above-mentioned sound insulation and noise reduction blackout curtain structure. In this embodiment, the rectangular structure of the bed curtain 20, the surrounding and top sides of the bed curtain 20 can be formed by sewing five sound insulation and noise reduction blackout curtains, and the bottom of the bed curtain 20 is sewn with non-slip cloth. When in use, a mattress is laid on the non-slip cloth.

[0037] To facilitate assembly of the frame 30, see Figure 3-5 The skeleton 30 includes support rods 31 and connectors 32. Twelve support rods 31 form a rectangular parallelepiped frame structure through eight connectors 32. The connectors 32 are three-way structures in three directions of XYZ, and the support rods 31 are inserted into the connectors 32.

[0038] Embodiment three:

[0039] Since a good sound insulation and noise reduction effect is required, the inside of the bed curtain 20 is relatively closed, which causes air to stagnate. Figure 2-7 The bed curtain 20 is provided with an interpenetrating hole, and the support rod 31 located on one side or both sides of the top is a pipe fitting and passes through the connecting piece 32, and the support rod 31 passing through the connecting piece 32 passes through the interpenetrating hole again; the support rod 31 located on one side or both sides of the top is provided with an exhaust hole 311, and exhaust ports 312 are formed at both ends of the support rod 31; and an air supply device 40 is also included, and the air supply device 40 includes an air pump 43, and a pipe 42 is connected to the exhaust port of the air pump 43, and the pipe 42 passes into the bed curtain 20 from the interpenetrating hole. The air pump 43 is used to inject fresh air into the bed curtain 20, and the air in the bed curtain 20 enters the exhaust hole 311 on the support rod 31, and finally is discharged from the exhaust port 312. In this way, ventilation is ensured, and mosquitoes will not enter the bed curtain 20 from the interpenetrating hole when not in use.

[0040] When used, the insertion holes at both ends of the support rods 31 on one or both sides of the top of the bed curtain 20 are slightly larger than the diameter of the support rods 31. After the air cushion layer 14 is inflated, the diameter of the insertion holes becomes smaller, thereby closing the gap between the insertion holes and the support rods 31. Figure 6 The connecting member 32 is tightly matched with the support rod 31 , or a screw is screwed on the connecting member 32 to abut against the support rod 31 to prevent the connecting member 32 from sliding on the support rod 31 .

[0041] The support rod 31 can be made of stainless steel or iron paint tube with a diameter of 16-20 mm.

[0042] The air pump 43 is a small silent air pump, and the air pump 43 is located outside the bed curtain 20 .

[0043] Embodiment 4:

[0044] Based on Example 3, see Figure 7 The air supply device 40 further includes an air dispersion device 41, which is installed on the inner wall of the bed curtain 20, and is provided with air dispersion holes 411, and the pipeline 42 is connected to the air dispersion device 41. The air dispersion effect of fresh air entering the bed curtain 20 is improved.

[0045] In this embodiment, the wind dispersing device 41 is a bag-shaped structure, and the wind dispersing device 41 is attached to the inner wall of the bed curtain 20. Specifically, the wind dispersing device 41 can be attached to the top and side walls of the bed curtain 20 by Velcro.

[0046] The working principle or action process of the utility model is as follows:

[0047] When in use, the frame 30 is assembled in the bed curtain 20 of the integrated structure. Since the air cushion layer 14 in the bed curtain 20 has not been inflated at this time, the bed curtain 20 has a larger space than the frame 30, so that the frame 30 can be assembled. Then, the air pump is connected to the inflation nozzle 15, and the air is inflated into each air cushion layer 14 through the air pump. After the air cushion layer 14 is inflated, it expands inward, thereby squeezing the frame 30, so that the bed curtain 20 and the frame 30 are fixed. Then, the bed curtain 20 can be lifted onto the bed, and a mattress or cotton quilt can be placed on the protective layer.

[0048] Before entering the bed curtain 20 , the air pump 43 is first connected to a power source, and the air pump works to input fresh air into the bed curtain 20 .
