[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] See Figures 1-6 This utility model provides an inflatable mattress with a protective layer, which includes an inflatable mattress body 1 and a protective layer 3 disposed on the upper surface of the inflatable mattress body 1.

[0030] The air mattress body 1, serving as the support carrier, is made of flexible material. A sealed chamber is formed within the air mattress body 1, creating an inflation chamber. When inflated, it takes on a rectangular shape. An air valve is located on the side wall of the sealed chamber, connecting to an air pump for inflating and deflating the chamber. This valve has a valve core; when connected to the air pump, the valve core opens, connecting the pump and the inflation chamber. Inflation and deflation can then be performed. Simultaneously, the valve core can be manually pressed to manually release pressure, adjusting the inflation chamber pressure and thus achieving manual adjustment of firmness to maintain the comfort of the air mattress. When all internal air is expelled, it can be folded and collapsed. The air valve serves as the operating terminal for inflation, deflation, and pressure relief adjustment. In this embodiment, the air mattress 1 is made of TPU material, which has good weather resistance and flexibility, and can maintain good physical properties even after long-term use, resulting in a long service life. In order to intuitively understand the internal air pressure status, a pressure gauge interface is also provided on the side wall of the inflation chamber for installing a pressure gauge, thereby accurately displaying the internal air pressure and realizing precise control of the mattress firmness. The air valve and pressure gauge interface are located in the same position, which improves the convenience of operation and facilitates manufacturing. In this application, the valve is located at the center of the tail end of the mattress for easy inflation and deflation operations.

[0031] In this application, a protective layer 3 is provided on the upper surface of the air mattress body 1. The protective layer 3 is substantially the same size as the upper surface of the air mattress body 1, covering the entire upper surface of the air mattress body 1. The edge 32 of the protective layer 3 is fitted and fixed to the upper surface or edge of the air mattress body 1. In this application, the connection between the two can be achieved by adhesive, ultrasonic welding, or hot melting, so that the protective layer 3 and the air mattress body 1 are tightly bonded, ensuring that they do not shift during use and that the connection strength is high. In this application, there is a gap between the lower surface of the protective layer 3 and the upper surface of the air mattress body 1, thus forming a cavity. This cavity serves as a filling cavity, and an elastic layer 4 is provided inside the filling cavity. The elastic layer 4 is made of elastic material and is elastic in itself. By providing the above-mentioned protective layer 3 and elastic layer, a certain distance can be maintained between the entire upper surface of the mattress and the upper surface of the air mattress body, thereby protecting the air mattress body and preventing friction during use. Air leakage may occur due to damage from sharp objects, while the elastic layer 4 effectively disperses body pressure, improves comfort, extends the mattress's lifespan, and enhances its heat retention, resulting in a better user experience. The thickness of the elastic layer 4 can be adjusted according to user needs to further optimize support. In this embodiment, the thickness of the filling cavity (elastic layer) is greater than or equal to 5mm and less than or equal to 50mm, preferably 10mm-20mm, ensuring suitable support and cushioning for users of different weights and sleeping habits, reducing localized pressure concentration, and improving sleep quality. In this application, the elastic layer 4 is a sponge, preferably a closed-cell sponge. Closed-cell sponge is a sponge material with a unique structure where the internal pores are independent and closed. Using closed-cell sponge as the elastic layer of an air mattress has a series of significant advantages, making it an ideal choice in air mattress manufacturing. The following is a detailed explanation of the advantages of closed-cell sponge as the elastic layer of an air mattress:

[0032] 1. Excellent physical properties:

[0033] Density and weight: The density of closed-cell foam is usually between 0.03g / cm3 and 0.8g / cm3, which makes it relatively lightweight and helps reduce the overall weight of the air mattress, making it easy to carry and move.

[0034] Elasticity: Although closed-cell foam is less elastic than latex foam and does not easily return to its original shape, it still has a certain degree of elasticity, which can provide the necessary support and resilience for air mattresses. This elasticity helps the mattress maintain its shape under pressure and is less likely to collapse, thereby improving comfort and extending the life of the mattress.

[0035] 2. Good durability;

[0036] Compression resistance: Due to its unique closed-cell structure, closed-cell foam has excellent compression resistance, which allows the mattress to withstand greater pressure without easily deforming during long-term use.

[0037] Abrasion resistance: Closed-cell foam also has good abrasion resistance, which can resist daily wear and tear and keep the mattress flat and comfortable.

[0038] 3. Shock absorption performance;

[0039] Shock absorption performance: Closed-cell foam also has good shock absorption performance, which can absorb and disperse vibrations from the ground, providing users with a more stable sleep experience.

[0040] 4. Adaptability and comfort;

[0041] Adaptability: The texture and elasticity of closed-cell foam can be adjusted as needed to meet the different needs of people for mattress firmness and comfort.

[0042] Comfort: As the elastic layer of an air mattress, closed-cell foam provides even support, distributes body pressure, reduces the number of times you toss and turn, and thus improves sleep quality.

[0043] 5. Cost and environmental friendliness;

[0044] Cost-effectiveness: Compared to other high-end mattress materials, closed-cell foam has a lower production cost, which makes air mattresses more affordable and cost-effective.

[0045] Therefore, closed-cell foam, as the elastic layer of an air mattress, possesses numerous advantages, including excellent physical properties, good durability, sound insulation and shock absorption, adaptability and comfort, as well as cost and environmental friendliness. These advantages make closed-cell foam an ideal choice in air mattress manufacturing, capable of meeting the performance needs of diverse groups of people.

[0046] In this application, the protective layer 3 includes a base layer and a fabric layer adhered to the upper surface of the base layer. The base layer serves as a connecting carrier for connecting with the air mattress, while the fabric layer enhances the tactile feel of the mattress surface, thus improving comfort. In this embodiment, the base layer uses the same material as the air mattress body 1, namely TPU material, giving it high strength and durability, as well as good waterproof and moisture-proof properties. The fabric layer uses woven fabric, providing a pleasant feel and comfortable use. TPU material has high strength, capable of withstanding significant weight and pressure without easily breaking, allowing the air mattress to maintain good shape and support performance during long-term use. TPU material also has good abrasion resistance, resisting daily wear and tear and extending the mattress's lifespan. The TPU air mattress has excellent waterproof performance, allowing it to be used in humid environments without moisture damage, which is particularly important for outdoor camping and other scenarios. It effectively prevents the mattress from getting damp due to rain or dew, and its moisture-proof properties help keep the mattress dry inside, preventing mold growth and maintaining cleanliness and hygiene.

[0047] In this application, the filling cavity can be a sealed chamber. At the same time, a secondary air valve is provided on the side wall of the filling cavity for inflating and deflating the filling cavity, which can improve the hardness of the upper surface. In order to prevent the protective layer from bulging due to excessive pressure in the filling cavity, the upper and lower surfaces of the internal elastic layer are respectively attached to the inner surface of the protective layer and the upper surface of the inflatable mattress body. This can prevent the protective layer from bulging when the pressure is high, maintain the flatness of the upper surface of the mattress, and provide a good user experience.

[0048] Meanwhile, a wire-drawing structure 2 is provided inside the air mattress body 1. The wire-drawing structure 2 includes an upper base fabric layer 21 and a lower base fabric layer 22 arranged in parallel. A wire 23 is provided between the upper base fabric layer 21 and the lower base fabric layer 22. The upper base fabric layer 21 is attached and fixed to the upper surface of the air cavity by adhesive or other means, and the lower base fabric layer 22 is attached and fixed to the lower surface of the air cavity by adhesive or other means. The wire-drawing structure enhances the overall stability of the mattress, prevents deformation after inflation, ensures uniform support during long-term use, and further improves the user experience.

[0049] Meanwhile, due to the protective layer and elastic layer on the upper surface, there is a difference in elasticity between the upper and lower surfaces, which can easily cause deformation after inflation. To avoid the above problems, in this application, a balancing layer 5 is attached to the bottom surface of the inflatable mattress body 1. The balancing layer 5 can make the upper and lower surfaces of the inflatable mattress body have the same elastic (deformation) coefficient, ensuring that the mattress is flat after inflation and avoiding deformation. The material of the balancing layer 5 is the same as that of the protective layer, which is TPU material in this application. It can also improve the wear resistance of the lower surface and increase the service life.
