[0036] Furthermore, the sealing cloth 1 can be connected to the side cloth 4, and the sealing cloth 1 can also be connected to the connecting structure 5. Specifically, when the area of ​​the sealing cloth 1 is larger than the connecting structure 4, the sealing cloth 1 can be connected to the side cloth 4 or to the connecting structure 5; when the area of ​​the sealing cloth 1 is smaller than the connecting structure 5, the sealing cloth 1 can be connected to the connecting structure 5.

[0037] Embodiment 3

[0038] The connection structure 5 includes a top layer 6, a bottom layer 7 and a connection object 8, one side of the connection object 8 is connected to the top layer 6, and the other side of the connection object 8 is connected to the bottom layer 7. The connection structure 5 is a structure for enhancing the stability of the sleeping pad. The two sides of the connection object 8 are respectively connected to the top layer 6 and the bottom layer 7, which can make the surface of the inflatable sleeping pad, pillow or cushion very flat and enhance the load-bearing stability, and can enhance the support and comfort of the cushion layer.

[0039] The connector 8 is at least one of a wire drawing structure, a drawstring structure, and a column structure.

More preferably, the two ends of the connector 8 are connected to the top layer 6 and the bottom layer 7 respectively by plastic. The plastic can also be a material with adhesive properties, such as TPU, PV, and PU. The middle part of the connector 8 is a wire drawing, a drawstring, or a column. The top layer 6, the bottom layer 7 and the connecting object 8 constitute a brushed cloth (polyester fiber space brushed cloth), that is, the two ends of the connecting object 8 are fixedly connected to the top layer 6 and the bottom layer 7 respectively, and then a TPU / PVC film is laid on the outer side of the top layer 6 and the top layer 7; preferably, the top layer 6 and the bottom layer 7 can also be directly TPU / PVC film, or a patchwork cloth made of multiple material cloths, and the top layer 6 and the bottom layer 7 are used to connect the connecting object 8 in the middle.

[0040] More preferably, the lower end of the top layer 6 and the upper end of the bottom layer 7 can be fixedly connected to form a side cloth 4 structure, and the lower end of the top layer 6 and the upper end of the bottom layer 7 are connected so that a sealed cavity structure is formed between the top layer 6 and the bottom layer 7.

[0041] Embodiment 4

[0042] The connecting structure 5 also includes an annular side curtain 9, which is arranged next to the top layer 6 and the bottom layer 7; one end of the annular side curtain 9 located at the top layer 6 is connected to the top layer 6, and the other end is connected to the side cloth 4; one end of the annular side curtain 9 located at the bottom layer 7 is connected to the top layer 6, and the other end is connected to the side cloth 4.

[0043] One end of the annular side curtain 9 at the upper end is connected to the top layer 6, and the other end is connected to the side cloth 4, and one end of the annular side curtain 9 at the lower end is connected to the bottom layer 7, and the other end is connected to the side cloth 4. The annular side curtain 9 is used to strengthen the connection stability of the top layer 6 and the bottom layer 7 in the connection structure 5 and the side cloth 4, and increase the contact area of ​​the connection.

[0044] Furthermore, when the top layer 6 and the bottom layer 7 are directly connected to form the side fabric 4, the annular side curtain 9 is used to strengthen the connection stability between the top layer 6 and the bottom layer 7, that is, the annular side curtain 9 of the top layer 6 and the annular side curtain 9 of the bottom layer 7 are fixedly connected.

[0045] The annular side curtain 9 can be continuous and annularly closed, and the annular side curtain 9 has no gaps, such as an annular long strip. Further, the annular side curtain 9 can be in a discontinuous form, that is, the annular side curtain 9 is in a discontinuous transition form. For example, the annular side curtain 9 can be composed of four sub-side curtains around the cushion, and there are gaps between adjacent sub-side curtains. In other embodiments, the annular side curtain 9 can be composed of more than four sub-side curtains, and there are gaps between adjacent sub-side curtains. Furthermore, the annular side curtain 9 can be continuous and annularly closed, and the annular side curtain 9 has at least one through hole, which is used to allow the air on both sides of the annular side curtain 9 to pass through the through hole when air is poured into the inflatable cushion.

[0046] Embodiment 5

[0047] The sealing cloth 1 is breathable. In one embodiment, the sealing cloth 1 can be made of breathable materials, such as linen, cotton, woven fabric, etc., and the breathable effect is achieved through the gaps in the material itself; in another embodiment, the sealing cloth 1 material itself is not breathable, such as a plastic film, etc., and is provided with a plurality of air holes 12 to achieve breathability; there are other embodiments, such as using breathable materials such as linen, cotton, woven fabric, etc., and providing air holes 12 on the sealing cloth 1. The sealing cloth 1 is breathable, so that when storing, excess gas can be discharged without affecting storage, and ventilation is possible.

[0048] The sealing cloth 1 can be made of woven cloth, such as pure cotton and other materials. Pure cotton and other materials themselves have a certain air permeability. A number of air holes 12 can be set on the sealing cloth 1 to further enhance the air permeability of the sealing cloth 1; further, the sealing cloth 1 also uses non-woven cloth. The material of the non-woven cloth can be composed of polyethylene resin and polypropylene resin superimposed, or it can be TPU, PVC composite cloth, or TPU, PVC film, etc., or the sealing cloth 1 can be formed by splicing and stacking woven cloth and non-woven cloth; the non-woven cloth has high elasticity, and the air holes 12 are set on the non-woven cloth. Due to its high elasticity, the air permeability will increase according to the weight of the user, that is, when the user lies or leans on the cushion, the sealing cloth 1 is concave due to the weight. At this time, the non-woven cloth stretches, and the air holes 12 are stretched and enlarged accordingly to increase the air permeability. More preferably, the sealing cloth 1 can also be a nylon material or other elastic cloth. More preferably, the sealing cloth 1 can be a slightly breathable or non-breathable composite fabric, such as a sealing cloth 1 composed of three fabric layers, namely, the outermost layer of polyester material, the middle layer of film, and the innermost layer of lining warp knitted fabric. The fabric composed of this structure has low air permeability or almost negligible air permeability.

[0049] Furthermore, the air permeability of the sealing cloth 1 is achieved by fixing a partial area of ​​the lower side of the sealing cloth 1 and the upper side of the lower cushion layer 3. If there is one or more gaps in the connection between the sealing cloth 1 and the lower cushion layer 3, the structure can be used instead of the air holes 12 to achieve the purpose of not punching holes in the sealing cloth 1 while achieving air permeability. In particular, when there is one or more gaps in the connection between the sealing cloth 1 and the lower cushion layer 3, the annular side curtain 9 should be configured as a continuously sealed annular belt-shaped body. At this time, there are no through holes on the annular side curtain 9, and the air in the inflatable cushion will not penetrate into the area between the annular side curtain 9 and the side cloth 4.

[0050] When the fabric of the sealing cloth 1 is slightly breathable or non-breathable, the sealing cloth 1 can achieve the purpose of breathability by connecting with the underlying layer 3, that is, a partial area of ​​the lower side of the sealing cloth 1 is connected to a partial area of ​​the upper side of the underlying layer 3, and the connected area can be dispersed in a point-like manner on the lower side of the sealing cloth 1 and the corresponding position of the underlying layer 3, or it can be distributed in a discontinuous pattern or pattern on the lower side of the sealing cloth 1 and the corresponding position of the underlying layer 3. The connection can be a connection method such as bonding or hot melting. When in use, the sealing cloth 1 is compressed, squeezed, folded, etc., and work is performed. At this time, the gas between the sealing cloth 1 and the underlying layer 3 is squeezed out from the area where the sealing cloth 1 and the underlying layer 3 are not connected, thereby ensuring the overall breathability of the pad. In terms of appearance, the pattern formed by the connection can also increase the beauty of the pad.

Specifically, the handle 10 can be provided at the periphery or bottom of the side cloth 4. When the top layer 6 and the bottom layer 7 are connected to form the side cloth 4, the handle 10 can be provided at the bottom layer 7. If there is a position on the top layer 6 where the sealing cloth 1 is not laid, the handle 10 can be provided on the top layer 6. More preferably, the handle 10 can be one or more.

[0053] Embodiment 7

[0054] The side end of the lower cushion layer 3 is provided with an air nozzle 11. The side end of the lower cushion layer 3 is provided with an air nozzle 11 for inflation and deflation. Specifically, the air nozzle 11 can be arranged around the side cloth 4. When the top layer 6 and the bottom layer 7 are connected to form the side cloth 4, the air nozzle 11 can be arranged on the bottom layer 7. If there is a position on the top layer 6 where the sealing cloth 1 is not laid, the air nozzle 11 can be arranged on the top layer 6. More preferably, the air nozzle 11 can be one or more.

[0055] Embodiment 8
