Description

Technical Field

[0001] This utility model relates to the field of inflatable mattress technology, and in particular to an outdoor inflatable mattress that is comfortable to sleep on. Background Technology

[0002] Camping is a popular outdoor recreational activity, and camping mattresses are an essential piece of equipment. For portability and space efficiency, people often choose inflatable mattresses, which offer sufficient support and can be easily stored in a bag when not in use, maximizing space utilization. Traditional inflatable mattresses on the market typically consist of upper and lower sheets. These sheets are heat-sealed at high frequency to create a chamber, with air vents on the sides to allow air to fill and provide adequate support.

[0003] To enhance the comfort of air mattresses, current technologies typically involve improving the internal support structure; adjusting the surface undulations of the air chambers to mimic ergonomic curves and conform to the body's contours; or using a double-layer design, with a higher air pressure in the lower chamber for structural stability and a lower air pressure in the upper chamber for a soft feel. While these designs all improve comfort, they are relatively complex, have high production costs, and are susceptible to leaks if the upper layer cracks or ages, affecting the mattress's usability. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a comfortable outdoor inflatable mattress for sleeping.

[0005] The technical solution adopted by this utility model is as follows: a comfortable outdoor inflatable mattress, comprising, from top to bottom, an upper cover layer, a cushioning soft layer, a middle film layer, and a lower connecting layer, wherein the edges of the upper cover layer, the middle film layer, and the lower connecting layer are heat-sealed to form connecting ring edges; the cushioning soft layer is fixedly connected to the lower surface of the upper cover layer and located inside the inflatable mattress; a sealed inflation chamber is provided between the middle film layer and the lower connecting layer, the lower connecting layer has at least one inflation position, and a plurality of pull strap assemblies are provided between the middle film layer and the lower connecting layer.

[0006] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0007] Preferably, the cushioning layer is made of sponge material and is laid on the entire lower surface of the upper cover layer.

[0008] Preferably, the cushioning layer is fixed to the lower surface of the upper cover layer by adhesive or heat pressing.

[0009] Preferably, the buffer soft layer has a plurality of through holes arranged at intervals between each other.

[0010] Preferably, a heat-insulating aluminum film is fixedly adhered to the lower surface of the buffer soft layer.

[0011] Preferably, the inflation position is an inflation port, and the inflation port is provided with a cover.

[0012] Preferably, the pull strap assembly includes a first positioning piece fixed on the lower layer, a second positioning piece fixed on the intermediate film layer, and a pull strap disposed between the first positioning piece and the second positioning piece.

[0013] Preferably, the air mattress is in an inflated state, in which the air chamber is inflated and expands, and the intermediate membrane layer is stretched to fit against the heat-insulating aluminum film, or there is a gap between the intermediate membrane layer and the heat-insulating aluminum film.

[0014] Preferably, the intermediate film layer is a TPU film.

[0015] More preferably, the upper cover layer is the lower surface, and the upper surface of the lower bonding layer is both coated with a TPU film or a TPU coating.

[0016] Compared with the prior art, this utility model has the following beneficial effects:

[0017] 1. The space between the middle membrane layer and the lower layer is an inflatable chamber. Therefore, it is equivalent to adding an upper cover layer and a cushioning soft layer on top of the existing inflatable chamber. The design of the upper cover layer protects the user and allows direct contact with the human body, while the design of the cushioning soft layer can effectively increase the user's sleeping comfort.

[0018] 2. By setting an insulating aluminum film under the cushioning soft layer, the heat preservation effect of the air mattress can be effectively improved. During outdoor camping, users can lie on the air mattress, which is both comfortable and warm, making it very comfortable.

[0019] 3. Even if the upper cover layer cracks or ages, the air chamber will still remain airtight and will not affect the normal use of the air mattress. Attached Figure Description

[0033] Specific implementation plan:

[0034] Example 1:

[0035] See Figures 1-6 This utility model is a comfortable outdoor inflatable mattress, which includes, from top to bottom, an upper cover layer 1, a cushioning soft layer 5, a middle membrane layer 3, and a lower connecting layer 2. The edges of the upper cover layer 1, the middle membrane layer 3, and the lower connecting layer 2 are heat-sealed to form a connecting ring edge 8. The cushioning soft layer 5 is fixedly connected to the lower surface of the upper cover layer 1 and is located inside the inflatable mattress. A sealed air chamber is provided between the middle membrane layer 3 and the lower connecting layer 2. The lower connecting layer 2 has at least one air inflatable position. Several pull strap assemblies 4 are provided between the middle membrane layer 3 and the lower connecting layer 2.

[0036] In this embodiment, the connection between the edge of the upper cover layer 1, the edge of the middle film layer 3, and the edge of the lower connecting layer 2 can be achieved by high-frequency heat sealing, ultrasonic pressure welding, or heat sealing, and the optimal method can be selected according to different materials.

[0037] As a preferred embodiment of this invention, to enhance the heat retention effect of the air mattress, please refer to... Figure 3 As can be seen, a heat-insulating aluminum film is fixedly pasted on the lower surface of the buffer soft layer 5.

[0038] Then, please see Figures 1-3 As can be seen, the air mattress is in an inflatable state. In the inflatable state, the air chamber is inflated and expands, and the middle membrane layer 3 is stretched to fit with the heat-insulating aluminum film, or there is a gap between it and the heat-insulating aluminum film.

[0039] Note that after the inflation chamber is inflated, the space between the intermediate membrane layer 3 and the upper cover layer 1 is not inflated. Therefore, the upper cover layer 1 and the buffer soft layer 5 are actually stretched apart based on the inflation of the inflation chamber.

[0040] Since the edges of the upper cover layer 1, the middle film layer 3, and the lower layer 2 are fixed together by a high-frequency heat sealing process, and the heat-insulating aluminum film is fixed below the buffer soft layer 5, when the upper cover layer 1 and the buffer soft layer 5 are stretched open, the heat-insulating aluminum film will also be stretched open together. At this time, the heat-insulating aluminum film will adhere to the middle film layer 3. Of course, there may be a certain gap 7 between the two.

[0041] In this embodiment, the cushioning layer 5 is made of sponge and completely covers the lower surface of the upper cover layer 1. Furthermore, the cushioning layer 5 is fixed to the lower surface of the upper cover layer 1 by adhesive or heat pressing.

[0042] Since the cushioning layer 5 is made of sponge, it can be firmly fixed to the lower surface of the upper cover layer 1 by either adhesive or heat pressing.

[0043] Here, by laying a soft cushioning layer 5 made entirely of sponge material on the lower surface of the upper cover 1, when the user lies on top of the cover in an inflated state, they will feel very soft and have a great sleeping comfort.

[0044] Next, please refer to Figure 3 and Figure 4 As can be seen, in this embodiment, the buffer soft layer 5 is provided with a plurality of through holes 51 arranged at intervals.

[0045] Here, by setting multiple through holes 51 on the cushioning soft layer 5, on the one hand, the material effect of the cushioning soft layer 5 (improving the softness and comfort during the sleeping process) will not be affected, and on the other hand, the material cost of the cushioning soft layer 5 can be reduced.

[0046] Please see Figure 2 As can be seen in this embodiment, the inflation position is the inflation port 9, which is covered with a cap. After opening the cap, the user can inflate the inflation chamber by aligning the external air pump connector with the inflation port 9.

[0047] Please see Figure 3 , Figure 5 and Figure 6 In this embodiment, the pull strap assembly 4 includes a first positioning piece 42 fixed on the lower layer 2, a second positioning piece 43 fixed on the intermediate film layer 3, and a pull strap 41 disposed between the first positioning piece 42 and the second positioning piece 43.

[0048] The structure and working principle of the pull strap assembly 4 are existing technologies and will not be discussed in detail here. The pull strap assembly 4 is designed to provide structural support for the air chamber, thereby supporting the formation of the mattress's contour and ensuring that the air mattress does not deform during use.

[0049] More specifically, the intermediate film layer 3 is a TPU film, the upper cover layer 1 is the lower surface, and the upper surface of the lower connecting layer 2 are all coated with TPU film or TPU coating.

[0050] In this embodiment, the main materials of both the upper cover layer 1 and the lower cover layer 2 can be composite fabrics.

[0051] Here, since the middle film layer 3, the upper cover layer 1 (which is the lower surface), and the upper surface of the lower connecting layer 2 are all made of TPU, the edges of the upper cover layer 1, the middle film layer 3, and the lower connecting layer 2 can be sealed together using a high-frequency heat sealing process. This ensures that the air mattress will not leak air after inflation and is also more environmentally friendly.

[0052] Example 2: Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 7 Unlike Embodiment 1, the pull strap assembly 4 adopts a different structural design. In this embodiment, the first positioning piece 42 and the second positioning piece 43 are respectively disposed at the left and right ends of the lower connecting layer 2, and the pull strap 41 is disposed between the first positioning piece 42 and the second positioning piece 43, thereby forming a support structure different from that in Embodiment 1.

[0053] In practical applications, besides the pull belt assembly 4 disclosed in the two embodiments above, the pull belt assembly 4 can also be designed with other structures. Of course, these are all prior art, so they will only be briefly described here.

[0054] The above description of a comfortable outdoor inflatable mattress according to the present invention is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the inventive concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
