[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1-Figure 6 The present invention provides an air mattress with a protective layer, which includes an air mattress body 1 and a protective layer 3 arranged on the upper surface of the air mattress body 1.

[0030] The inflatable mattress body 1 is used as a supporting carrier and is made of a flexible material. A sealed chamber is formed in the inflatable mattress body 1 to form an inflation chamber. After being inflated, it is in the shape of a rectangular parallelepiped. An air valve is provided on the side wall of the sealed chamber. The air valve is used to connect an air pump to inflate and evacuate the sealed chamber. The air valve has a valve core. When connected to the air pump, the valve core can be pushed open to connect the air pump and the inflation chamber. At this time, inflation and exhaust can be performed. At the same time, the valve core can be manually pressed to achieve manual pressure relief to adjust the inflation chamber pressure and achieve manual adjustment, thereby achieving soft and hard adjustment to maintain the comfort of the inflatable mattress. When all the internal gas is discharged, it can be folded and gathered, that is, the air pump can be manually pressed to achieve manual pressure relief to adjust the inflation chamber pressure and achieve manual adjustment, thereby achieving soft and hard adjustment to maintain the comfort of the inflatable mattress. The air valve serves as the operating end for inflation, exhaust and pressure relief adjustment; in the present embodiment, the inflatable mattress 1 is made of TPU material, which has good weather resistance and flexibility. Even after long-term use, it can maintain good physical properties and a long service life; in order to intuitively understand the internal air pressure state, in the present application, a pressure gauge interface is also provided on the side wall of the inflation cavity for installing a pressure gauge, so as to accurately display the internal air pressure and realize precise control of the softness and hardness of the mattress; the above-mentioned air valve and pressure gauge interface are located in the same position, which improves the convenience of operation and is convenient for processing and manufacturing. In the present application, it is arranged at the center position of the tail end of the mattress to facilitate inflation and deflation operations.

[0031] In the present application, a protective layer 3 is provided on the upper surface of the inflatable mattress body 1. The size of the protective layer 3 is substantially the same as that of the upper surface of the inflatable mattress body 1 so as to cover the entire upper surface of the inflatable mattress body 1. The edge 32 of the protective layer 3 is fitted and fixed to the upper surface or the edge of the inflatable mattress body 1; in the present application, the connection between the two can be achieved by an adhesive or ultrasonic welding or hot melting, so that the protective layer 3 is tightly combined with the inflatable mattress body 1 to ensure that it does not shift during use and has a high connection strength; in the present application, there is a gap between the lower surface of the protective layer 3 and the upper surface of the inflatable mattress body 1, thereby forming a cavity, which serves as a filling cavity, and an elastic layer 4 is provided in the filling cavity. The elastic layer 4 is made of an elastic material and has elasticity itself. By providing the above-mentioned protective layer 3 and elastic layer, a certain distance can be made between the upper surface of the entire mattress and the upper surface of the inflatable mattress body, thereby protecting the inflatable mattress body and avoiding friction during use. Or damage caused by sharp objects and air leakage, at the same time, the elastic layer 4 can effectively disperse the pressure of the human body, improve comfort, and extend the service life of the mattress. The elastic layer improves the thermal insulation of the mattress, and the user experience is good; the thickness of the elastic layer 4 can be adjusted according to user needs to further optimize the support effect; 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, to ensure that when users with different weights and sleeping habits use it, it can provide appropriate support and cushioning, reduce local pressure concentration, and improve sleep quality; in this application, the elastic layer 4 is a sponge, preferably, the elastic layer 4 is a closed-cell sponge, which is a sponge material with a unique structure. The pores inside it are independent of each other, and these pores are all closed. Using closed-cell sponge as the elastic layer of an inflatable mattress has a series of significant advantages, which make closed-cell sponge an ideal choice in the manufacture of inflatable mattresses. The following is a detailed explanation of the advantages of closed-cell sponge as the elastic layer of an inflatable 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 inflatable mattress, making it easier to carry and move.

[0034] Elasticity: Although the elasticity of closed-cell sponge is poorer than that of latex sponge and it is not easy to return to its original shape, it still has a certain elasticity and can provide the necessary support and rebound performance for the inflatable mattress. This elasticity helps the mattress maintain its shape when under pressure and is not easy to collapse, thereby improving the comfort of use and extending the service life of the mattress.

[0035] 2. Good durability;

[0036] Compression resistance: Closed-cell sponge has excellent compression resistance due to its unique closed-cell structure, which enables the mattress to withstand greater pressure without being easily deformed during long-term use.

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

[0038] 3. Shock absorption performance;

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

[0040] 4. Adaptability and comfort;

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

[0042] Comfort: As the elastic layer of the air mattress, the closed-cell sponge can provide uniform support, disperse body pressure, reduce the number of tossing and turning, and thus improve sleep quality.

[0043] 5. Cost and environmental protection;

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

[0045] Therefore, as the elastic layer of the air mattress, the closed-cell sponge has many advantages, such as excellent physical properties, good durability, sound insulation and shock absorption, adaptability and comfort, cost and environmental protection, etc. These advantages make the closed-cell sponge an ideal choice in the manufacture of air mattresses, which can meet the requirements of different groups of people for mattress performance.

[0046] In the present application, the protective layer 3 includes a base layer and a fabric layer attached to the upper surface of the base layer, wherein the base layer is used as a connecting carrier for connecting to the inflatable mattress, and the fabric layer is used to improve the touch of the upper surface of the mattress, that is, to improve the comfort of use. In this embodiment, the base layer is made of the same material as the inflatable mattress body 1, that is, TPU material, so that the whole has high strength and durability, and good waterproofness and moisture resistance. The fabric layer is made of fabric fabric, which has good touch and is comfortable to use; TPU material has high strength characteristics, can withstand greater weight and pressure, and is not easy to break, which enables the inflatable mattress to maintain good shape and support performance during long-term use; TPU material has good wear resistance, can resist daily wear and tear, and extend the service life of the mattress; TPU inflatable mattress has excellent waterproof performance and can be used in a humid environment without being damaged by moisture, which is particularly important for outdoor camping and other scenes. It can effectively prevent the mattress from being damp due to rain or dew, and the moisture-proof performance helps to keep the inside of the mattress dry, prevent mold growth, and keep the mattress clean and hygienic.

[0047] In the present application, the filling cavity can be a sealed cavity. At the same time, a secondary air valve is provided on the side wall of the filling cavity for inflating and exhausting the filling cavity, which can increase the hardness of the upper surface. In order to avoid 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, which can avoid 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] At the same time, a brushed structure 2 is provided in the inflatable mattress body 1, and the brushed structure 2 includes an upper base fabric layer 21 and a lower base fabric layer 22 arranged in parallel, and a brushed 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 bonded and fixed to the upper surface of the inflation cavity by an adhesive or other means, and the lower base fabric layer 22 is bonded and fixed to the lower surface of the inflation cavity by an adhesive or other means. The brushed 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] At the same time, since a protective layer and an elastic layer are arranged on the upper surface, resulting in a difference in elasticity between the upper and lower surfaces, deformation is likely to occur after inflation. In order to avoid the above problems, in the present application, a balancing layer 5 is fitted and installed on 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 in a flat state after inflation to avoid deformation; the material of the balancing layer 5 is the same as that of the protective layer, which is TPU material in the present application, and can also improve the wear resistance of the lower surface and increase the service life.

[0050] The inflatable mattress with a protective layer of the present invention is provided with a protective layer, which can effectively protect the upper surface, improve wear resistance and service life, and has a heat preservation function, and is comfortable to use; at the same time, an elastic layer is provided between the protective layer and the inflatable mattress body, and the elastic layer can buffer pressure, improve comfort, and prevent local depression caused by long-term use; by providing the elastic layer, the distance between the upper surface of the mattress and the inflation cavity is increased, and the protection of the inflatable mattress body is further enhanced, and air leakage caused by damage caused by friction or sharp objects during use is avoided, and at the same time, the heat preservation is further improved; the elastic layer adopts closed-cell sponge, which is light in weight, good in elasticity, comfortable to use, and good in heat preservation; the filling cavity adopts The inflatable structure can adjust the hardness to meet different usage requirements, has a good user experience and a wide range of applications; the overall TPU material is used to make the overall mattress have higher strength and durability, good waterproof and moisture resistance, and a long service life; the brushed structure is set to enhance the overall stability of the mattress, prevent deformation after inflation, ensure uniform support during long-term use, and further improve the user experience; the balancing layer is set to make the upper and lower surfaces of the mattress have the same elastic coefficient, can produce synchronous expansion and contraction, avoid deformation, and have a good use effect; the inflatable mattress with a protective layer of the present invention has a compact structure, has a heat preservation function, is comfortable to use, has good wear resistance, has a certain anti-scratch function, and has a long service life.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
