[0044] Embodiment 1

[0045] See also Figure 1 and Figure 2 The inflatable sleeping pad provided in this embodiment comprises a sleeping pad layer 1 and an inflatable layer, wherein the lower end of the sleeping pad layer 1 is connected to the upper end of the inflatable layer;

[0046] The inflatable layer includes a plurality of independently inflated air cushion layer structures 2, and each layer of the air cushion layer structures 2 is connected to each other;

[0047] The air cushion layer structure 2 includes a cover film 21, a bottom film 22, a side film 23 and a pulling connector 24; one end of the pulling connector 24 is connected to the cover film 21, and the other end of the pulling connector 24 is connected to the bottom film 22; the side ends of the cover film 21 and the bottom film 22 are sealed and connected through the side film 23;

[0048] A gas charging and discharging port 27 is provided on the side membrane of each layer of the air cushion layer structure 2;

[0049] The bottom film 22 of the air cushion layer structure 2 on the upper layer is connected to the cover film 21 of the air cushion layer structure 2 on the lower layer, and the cover film 21 of the uppermost air cushion layer structure 2 is connected to the bottom end of the sleeping pad layer 1 .

[0050] The inflatable sleeping mat of this embodiment can adjust the height of the lower air cushion layer structure 2 by setting up a plurality of independently inflated air cushion layer structures 2, and inflate and deflate the air cushion layer structure 2 as needed, so that the inflatable sleeping mat meets the height adjustment requirements, and the upper layer remains inflated, so that the inflatable sleeping mat meets the support hardness requirements and will not become a support soft state, so that the inflatable sleeping mat can well take into account stability and comfort, and solves the problem in the prior art that the current outdoor inflatable sleeping mats cannot meet the requirements of both height and support hardness at the same time.

[0051] In the present embodiment, a double-layer connected air cushion layer structure 2 is adopted. When the height of the inflatable sleeping mattress needs to be lowered, the air can be deflated through the gas filling and discharging port 27 of the lower air cushion layer structure 2. After the gas is discharged, the height of the inflatable sleeping mattress is lowered to an appropriate height. At the same time, the upper air cushion layer structure 2 remains inflated, which meets the good support requirements. In this way, not only the height adjustment requirements of the inflatable sleeping mattress can be met, but also the support hardness requirements of the inflatable sleeping mattress can be met, and the inflatable sleeping mattress will not become a soft support state, so that the inflatable sleeping mattress can well take into account stability and comfort.

[0052] Of course, in other embodiments, a three-layer connected air cushion layer structure 2 or an air cushion layer structure 2 with more than three layers connected may also be provided. The specific number of layers of the air cushion layer structure 2 is not specifically limited and can be designed according to actual practicality.

[0053] In this embodiment, the side ends of the cover film 21 and the bottom film 22 are sealed by the side film 23, which can ensure the good sealing of the air cushion structure 2 and prevent air leakage during use. At the same time, it should be noted that the sealing connection between the cover film 21 and the side film 23 and the bottom film 22 and the side film 23 can be connected by hot pressing or bonding, and any connection method with a sealing effect meets the requirements. No specific limitation is made here.

[0054] In this embodiment, the bottom film 22 of the upper air cushion layer structure 2 and the cover film 21 of the lower air cushion layer structure 2 can realize a double-layer structure or a multi-layer structure by means of hot pressing, bonding, and sewing. For example, during hot pressing, the bottom film 22 of the upper air cushion layer structure 2 and the cover film 21 of the lower air cushion layer structure 1 are in close contact to complete the gluing process.

[0055] In this embodiment, the gas charging and discharging port 27 provided on the side membrane 23 of each layer of the air cushion layer structure 2 is provided with a closing cover, and the gas charging and discharging port 27 and the closing cover can be connected and sealed by means of snap-fitting or the like to prevent leakage.

[0056] In this embodiment, a gas charging and discharging port 27 is arranged on the side membrane 23 on the same side of each air cushion layer structure 2. By arranging the gas charging and discharging ports 27 of all air cushion layer structures 2 on the same side, it is convenient to adjust the inflation and deflation of each air cushion layer structure 2 at the same time.

[0057] In a specific implementation, when it is necessary to adjust the height of the inflatable sleeping mattress (lower the height), the lower air cushion layer structure 2 is deflated and the upper air cushion layer structure 2 is filled with gas. By setting the gas filling and discharging ports 27 of all the air cushion layer structures 2 on the same side, such an inflation and deflation process does not require specific search for each air cushion layer structure 2, and simultaneous inflation and deflation adjustment of each air cushion layer structure 2 can be facilitated.

[0058] In some specific embodiments, the gas charging and discharging port 27 can be set on the middle part of the side membrane 23, which can be more convenient for the corresponding inflation process. Of course, in other embodiments, the gas charging and discharging port 27 can also be set at the lower end of the side membrane 23, so that the deflation process is more convenient. However, the position of the side membrane 23 where the gas charging and discharging port 27 can be set is not specifically limited, and can be selected and designed according to actual conditions.
