[0002] An inflatable cushion is a cushion that has strong flexibility and elasticity and expands in volume after being inflated. The inflatable cushion is elastic and easy to rebound after deformation. Although it looks very thick after being inflated, when the air in it is emptied, the inflatable cushion becomes very light and can be folded into a very small volume and put into a backpack to take away. It is very convenient and easy to carry. Due to the outstanding advantages of inflatable cushions, it has been rapidly developed in recent years, with more and more varieties and people's requirements for it are getting higher and higher. Multi-cavity and explosion-proof inflatable cushions have emerged. However, ordinary multi-cavity inflatable cushions use honeycomb (column) and drawstring (I-shaped) structures. Although the number of cavities is increased, it also makes inflation more troublesome and prolongs the inflation time. Explosion-proof inflatable cushions are made of higher-strength materials, which increases the cost. In addition, the inflatable cushion is directly exposed to the outside and is easily damaged by external forces, shortening the service life of the inflatable cushion or even directly scrapping it.

[0026] An inflation pipe 3 is provided in the cushion body 1 , and the inflation pipe 3 includes an air nozzle 301 . The air nozzle 301 penetrates the cushion body 1 and is fixedly connected to the cushion body 1 . Air is inflated into the cushion body 1 and the protection cushion 2 through the air nozzle 301 .

[0027] An air cap 3011 is provided at one end of the air nozzle 301. The diameter of the air cap 3011 is smaller than that of the air nozzle 301. The air cap 3011 is movably connected to the air nozzle 301. The air cap 3011 can be inserted into the air nozzle 301 to prevent debris from entering the inflation pipe 3. A valve 3012 is provided on the side of the air nozzle 301 close to the air cap 3011. Half of the edge of the valve 3012 is fixedly connected to the air nozzle 301, and the other half is suspended in the air. When there is no external force, the valve 3012 is perpendicular to the side wall of the air nozzle 301 to block the air nozzle 301. The valve 3012 is made of high-elastic rubber and can immediately return to its original position under the action of its own plasticity.

[0028] The inflation pipe 3 includes a horizontal air channel 302, which is fixedly connected to the air nozzle 301. A plurality of upper air outlets 303 are provided on the upper portion of the horizontal air channel 302 to inflate the air cavity 101. The upper air outlets 303 are fixedly connected to the horizontal air channel 302. The horizontal air channel 302 penetrates through the side wall 102 of the cushion body and enters each air cavity 101. The horizontal air channel 302 is fixedly connected to the side wall 102 of the cushion body.

[0029] A lower air outlet 304 is provided at the lower part of the horizontal air channel 302 to inflate the protection pad 2. The lower air outlet 304 is fixedly connected to the horizontal air channel 302. The lower air outlet 304 passes through the pipeline inlet 203 and is movably connected to the pipeline inlet 203. The protection pad 2 can be separated from the pad body 1 and can be inflated at the same time.

[0030] Lay the protective pad 2 on a flat ground with the side wall 201 facing upward, spread out the pad body 1, and insert the lower air outlets 304 into the corresponding pipe inlets 203 one by one. The high elastic rubber around the pipe inlet 203 will then seal the gap between the lower air outlets 304 and the pipe inlet 203 to prevent the protective pad 2 from leaking. Smooth the pad body 1 with your hands so that the Velcro corresponding to the protective pad 2 and the pad body 1 are firmly attached to prevent the protective pad 2 and the pad body 1 from sliding relative to each other. Pull the lower air outlet 304 out of the pipe inlet 203 of the protective pad 2, causing the protective pad 2 to leak and lose its protective effect on the pad body 1. Unplug the air cap 3011, and insert the air needle of the external air pump into the air nozzle 301. Since half of the edge of the valve 3012 is in contact with the air nozzle 3 01 is sealed and connected, and the other half is suspended and made of high-elastic rubber. When not affected by external force, valve 3012 is perpendicular to the side wall of air nozzle 301 to block air nozzle 301. When the air needle of the external air pump is inserted, under the squeezing of the air needle, the suspended side of valve 301 rises inward to form a gap between the air nozzle 301 and the air needle. The air needle is inserted into the inflation pipe 3 from the gap, and the air pump is turned on to inflate the air nozzle 301. The air enters the horizontal airway 302 through the air needle.

Part of the air enters the middle air cavity 101 from the upper air outlet 303, and part of the air enters the protective pad 2 from the lower air outlet 304. Each air cavity 101 can be inflated at the same time, which is simple to operate and reduces inflation. After the inflation is completed, the air needle is pulled out, and the valve 3012 immediately returns to its original position under the action of its own plasticity, blocking the air nozzle 301, so that the air in the cushion body 1 and the protective pad 2 will not leak out, and the air cap 3011 is plugged back into the air nozzle 301 to prevent small objects from entering the air nozzle 301 to open the valve 3012, causing the cushion body 1 and the protective pad 2 to leak; the cushion body surface layer 103 and the protective pad surface layer 204 have the same structure and are composited with multiple materials, including PVC, carbon fiber and polyester fiber from the inside to the outside. PVC has strong flexibility, elasticity, dense texture and no air leakage. It is the base material of the cushion body 1 and the protective pad 2. Carbon fiber has high strength, low density and thin thickness, and basically does not increase the deadweight and cross-sectional size of the cushion body 1 and the protective pad 2, while restraining P The VC base layer will not explode due to huge deformation caused by excessive pressure, thereby extending the service life of the inflatable cushion. Polyester fiber has excellent wrinkle resistance and shape retention, which improves the comfort of the cushion body 1 and the protective pad 2 when they are in contact with the human body. The protective pad 2 is in direct contact with the ground and is easily damaged. When the protective pad 2 is damaged beyond repair, tear off the Velcro of the cushion body 1 and the protective pad 2, and pull out the lower air outlet 304 from the pipe inlet 203 of the protective pad 2, and then plug the lower air outlet 304 into the pipe inlet 203 of the new protective pad 2. There is no need to replace the cushion body 1 and the protective pad 2 at the same time, which reduces costs. After use, unplug the air cap 3011, and use an object like a cotton swab to press the valve 3012 backwards to squeeze out the air in the inflatable cushion, and then fold it for storage.
