[0035] The second airbag 4 is arranged on the top of the first airbag 3 , and the second airbag 4 is arranged on the inner side of the wrapping layer 1 .

[0036] A connecting piece 41 is fixedly mounted on the inner side surface of the second airbag 4 . The top and bottom of the connecting piece 41 are respectively fixedly mounted on the top and bottom of the inner side surface of the second airbag 4 . A through hole 42 is formed inside the connecting piece 41 .

[0037] One end of the plurality of first one-way valves 13 is fixedly installed on one side of the first airbag 3 , and one end of the plurality of second one-way valves 16 is fixedly installed on the other side of the first airbag 3 .

[0038] One of the first one-way valves 13 is fixedly installed on one side of one end of the second airbag 4 , and one of the second one-way valves 16 is fixedly installed on the other side of one end of the second airbag 4 .

[0039] An anti-wear pad 2 is provided at the bottom of the wrapping layer 1 .

[0042] The working principle of the inflatable mattress with multiple layers and multiple air chambers provided by the utility model is as follows:

[0043] When in use, the user places the inflatable mattress in a suitable position, then connects the inflation pump and the inflation port 11, and then inflates the interior of the inflation port 11. At this time, the gas enters the first airbag 3 and the second airbag 4 respectively through the air inlet pipe 14 and the first one-way valve 13. At this time, since the interior of the first airbag 3 is divided into multiple separate air chambers by the partition 32, multiple first one-way valves 13 are installed on one side of the first airbag 3 for inflating each air chamber separately. When it is used subsequently, when one of them is punctured, it will not cause leakage of other air chambers. When it is necessary to pump air, the vacuum pump and the air release port 12 can be connected. At this time, the gas inside the multiple air chambers enters the interior of the air outlet pipe 15 through the multiple second one-way valves, and then is discharged through the air release port 12.

[0044] Compared with the related art, the inflatable mattress with a multi-layer and multi-air chamber structure provided by the utility model has the following beneficial effects:

[0045] By cooperating with each other through structures such as the second airbag 4, the first airbag 3, the sponge 31, the spacer 32, the inflation port 11, the deflation port 12, the first one-way valve 13, the air outlet pipe 15 and the second one-way valve 16, when in use, the interior of the first airbag 3 arranged at the bottom of the second airbag 4 can be divided into multiple separate air chambers, and air is supplied separately. This can protect the second airbag 4 and prevent the bottom of the inflatable mattress from being punctured, causing the entire air to leak and become unusable, thereby increasing the service life of the inflatable mattress.
