[0038] Combination Figure 1-4 , an inflatable sofa, comprising

[0039] The sofa body includes a first airbag 2 and a second airbag 3, wherein the first airbag 2 encloses a cylindrical accommodating chamber a; the second airbag 3 is located in the accommodating chamber a, and the second airbag 3 is connected to the first airbag 2 through a gas passage b; the first airbag 2 is provided with an inflation nozzle 23; specifically, the first airbag 2 and the second airbag 3 can be made of materials such as TPU composite, TPU, TPU flocking, PVC composite, PVC, PVC flocking, EVA composite, EVA, and EVA flocking; after cutting the pieces that meet the sofa shape design requirements, the pieces are spliced ​​or overlapped to form a sealed cavity so that it can withstand sufficient pressure; preferably, the splicing or overlapping parts can be connected by bonding, high-temperature welding or ultrasonic welding. In addition to its basic functions, the sofa also needs to have a better shape to enhance its market competitiveness. However, the shape of ordinary airbags after inflation is often round or cylindrical, which is difficult to meet various shape changes. Therefore, in order to enable the first airbag 2 and the second airbag 3 to achieve the required shape after inflation, the present embodiment further preferably provides a plurality of shaping reinforcements 22 / 32 in the first airbag 2 and the second airbag 3. By adaptively designing and cutting the shape and size of the shaping reinforcement and connecting the shaping reinforcement in the airbag, the shape change of the airbag can be restricted during the inflation process, so that it can expand and change according to the required shape of the design.

[0040] It should be noted that, in the present embodiment, the first airbag 2 forms the sofa backrest and the sofa armrest, and the second airbag 3 mainly supports the weight of the user; specifically, the height of the first airbag 2 at the sofa backrest is much higher than that of the second airbag 3, and the height is highest in the middle of the sofa backrest, and then transitions to the curved surface in front of the sofa and the height gradually decreases, forming a streamlined sofa armrest. The streamlined armrest is more ergonomically designed, making it more comfortable for users to lean on and at the same time having good support; then the first airbag 2 is basically level with the height of the second airbag 3 in the front of the sofa. When the user sits on the sofa, the buttocks are supported by the upper end of the second airbag, and the thighs are supported by the first airbag 2. The first airbag 2 is basically level with the height of the second airbag 3 in the front of the sofa, so that the buttocks can be fully supported, avoiding compression of the thighs and causing discomfort to the user.

[0041] The outer cover body 1 includes an outer periphery 11, an inner periphery 12, an upper piece 15 and a large bottom 14. The large bottom 14 is located below the sofa body, and the upper piece 15 is located above the second airbag 3; the outer periphery 11 and the inner periphery 12 are respectively covered on the outer side and the inner side of the first airbag 2, one end of the two is connected to each other, and the other end extends to the sofa base 4 and is fixedly connected to the large bottom 14; since the first airbag and the second airbag are connected through the gas passage b, and after the first airbag and the second airbag are installed, the inner periphery is located between the first airbag and the second airbag The gas passage b is located in the airbag passage 121. The airbag passage 121 can avoid the gas passage b and avoid affecting the gas passage b. The outer edge of the upper piece 15 is preferably connected to the inner piece 12 to shield the accommodating chamber a, thereby shielding the second airbag 3.

[0042] The sofa base 4 is fixedly arranged at the bottom of the sofa body, and is used to provide good support for the sofa body. Specifically, in this embodiment, the sofa base 4 preferably includes a base assembly 41, and the base assembly 41 is located between the second airbag 3 and the large bottom 14; the base assembly 41 includes a bottom plate 412, and the bottom plate 412 is covered with a bottom plate outer cover 411, and the bottom plate outer cover 411 is connected to the large bottom 14. Preferably, the bottom plate 412 is a wooden board. In this embodiment, the bottom plate is first covered with the bottom plate outer cover 411. The purpose is that in this embodiment, the second airbag 3 is directly located above the bottom plate 412. If the second airbag 3 is in direct contact with the bottom plate 412, the wear of the second airbag 3 will be aggravated during use, and its service life will be reduced. By separating the bottom plate outer cover 411 between the bottom plate and the second airbag 3, the second airbag 3 can be well protected and its service life can be extended. This embodiment further preferably extends the inner periphery 12 toward the sofa base 4 and then sews the outer cover 411 of the bottom plate together with the outsole 14 , which shortens the processing steps on the one hand and makes the structure more integrated on the other hand, and the connection strength and support stability will also be greatly improved.

[0043] It is further preferred that the sofa base 4 also includes a support assembly 42, which is fixedly arranged below the base assembly 41 and is rotatable. Specifically, the support assembly includes a connecting plate 421, a rotating shaft 422 and a base 423. The connecting plate 421 has a screw mounting hole, and the support assembly 42 can be fixedly connected to the base assembly 41 by passing the screw through the screw mounting hole and screwing into the bottom plate 412. Since the bottom plate 412 is tightly covered by the bottom plate outer cover 411, and the bottom plate outer cover 411 is connected to the outer bottom 14 at the same time, after the first airbag and the second airbag are filled with air, the bottom plate 412 will be firmly tightened by the bottom plate outer cover 411, the outer bottom 14 and the inner bottom 12, so that the support assembly 42 can be firmly fixed to the bottom of the sofa body, and the sofa body can be stably supported. In addition, in this embodiment, due to the existence of the rotating shaft 422, the sofa body can be horizontally rotated, thereby improving the flexibility and convenience of the sofa. It should be noted that the rotatable support assembly here is the same as the prior art, and a sofa rotating base can be preferred. It should be noted that the outer cover body 1 in this embodiment, on the one hand, serves to beautify and protect the first airbag and the second airbag; on the other hand, it also serves to connect and stably connect and fix the first airbag, the second airbag and the base assembly, so that the support assembly can stably support the sofa body, and the problem of deflection and tipping will not occur during the user's use.

[0044] Considering that the sofa can provide the most basic support performance, its comfort is also a very important indicator for enhancing the user experience. For this reason, the present embodiment preferably also includes a sofa cushion 5, and the sofa cushion 5 is located above the second airbag. Specifically, the sofa cushion 5 includes an upper plate 52, and the upper plate 52 is located between the upper sheet 15 and the second airbag 3. A filler 51 is provided between the upper plate 52 and the upper sheet 15. Preferably, the upper plate 52 is made of EVA board, and the filler 51 is a flexible filler, such as sponge, cotton-like polyester fiber, etc., so that the upper plate 52 can reasonably distribute the weight of the user to the second airbag 3, and the flexible filler reduces the pressure on the user's buttocks and improves its comfort.

When the opening 711 is closed and the bag body 71 is squeezed, the gas in the bag body can be discharged from the inflatable port 73. Preferably, the material of the bag body 71 can be a woven fabric with a waterproof layer. Then, when the sofa needs to be inflated, it is only necessary to connect the inflation port 73 and the inflation nozzle 23 of the sofa, then fully expand the bag body 71, and then pinch the opening 711 and close the opening 711 by rolling the opening 711. Then, by further squeezing and rolling the bag body, the gas in the bag body can be forced to rush into the first airbag through the inflation port 73 and the inflation nozzle 23; the presence of the support strip 72 is more conducive to closing the opening 711 and convenient for rolling; after repeating the above actions many times, the first airbag and the second airbag can be filled.

[0046] In order to facilitate the carrying of the inflatable device 7, in this embodiment, the two ends of the bag opening 711 are preferably fixedly connected with connecting fasteners 74, and the connecting fasteners 74 are detachably connected with a shoulder strap, so that the shoulder strap can be connected when it is needed to be carried by hand or on the shoulder, thereby achieving hand carrying or shoulder carrying.
