Description

Technical Field

[0001] This utility model belongs to the field of inflatable product technology, specifically relating to an inflatable sleeping mat with a silver film. Background Technology

[0002] Traditional insulated air sleeping mats mostly use a single-layer or simple multi-layer structure, relying on the thermal insulation properties of the materials themselves to achieve heat retention. However, existing insulated air sleeping mats using a single-layer reflective film are unable to effectively block heat radiation, and heat is easily lost through air convection. If a multi-layer film is used, misalignment or separation between the layers can easily occur, leading to the failure of the insulation layer. Utility Model Content

[0003] The main purpose of this invention is to provide a thermal inflatable sleeping mat with a silver film. Through the alternating layering design of the silver film and the protective film, the specific opening layout and the welding point structure, the heat reflection path is optimized, the interlayer bonding force is enhanced, and the lightweight and durability are balanced, which significantly improves the thermal insulation performance and service life.

[0004] To achieve the above objectives, this utility model provides a thermal inflatable sleeping mat with a silver film. The thermal inflatable sleeping mat with a silver film includes an outer layer film, and the outer layer film contains three layers of silver film and two layers of protective film. A protective film is provided between two adjacent silver films.

[0005] The present invention provides an insulated inflatable sleeping pad with silver film. The three layers of silver film form a multi-reflective barrier, which effectively blocks the loss of heat radiation. The protective film serves as a spacer layer, which not only fixes the position of the silver film, but also enhances the pressure resistance of the sleeping pad through its high elasticity, preventing deformation after inflation.

[0006] In one possible implementation, the silver film has openings, with the openings in the upper and lower silver films aligned, and the openings in the middle silver film offset from those in the upper and lower silver films. The offset openings in the middle layer disrupt the heat radiation path, increase the number of heat reflections, and further improve the heat preservation efficiency.

[0007] In one possible implementation, a plurality of first weld points are provided between the two protective films. These first weld points are located within openings in the middle silver film and connect the two protective films. The first weld points fix the protective films at the openings in the middle silver film, preventing interlayer slippage and ensuring structural stability.

[0008] In one possible implementation, a second weld point is provided between the protective film and the inner surface of the outer layer of the sleeping mat, and the second weld point is located within the openings of the upper silver film and the lower silver film.

[0009] The second weld point integrates the outer membrane with the inner layer structure, preventing the outer membrane from expanding and separating during inflation.

[0010] In one possible implementation, the openings on the silver film are oblong. The rounded edges reduce stress concentration and lower the risk of fatigue cracking of the silver film due to repeated inflation and deflation.

[0011] In one possible implementation, the protective film is a TPU film or a plastic film. TPU film or silver film has good structural strength, which can stably fix the position of the silver film and improve the overall stability of the inflatable sleeping pad. Attached Figure Description

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0015] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0016] See attached diagram. Figure 1 , Figure 1 This is a schematic diagram of a thermal inflatable sleeping pad with a silver film provided in this application, as shown in the following figure. Figure 1 As shown, the present invention provides a thermal inflatable sleeping pad with silver film, including an outer layer film 1, wherein the outer layer film 1 is provided with three layers of silver film 2 and two layers of protective film 3, and a protective film 3 is provided between two adjacent layers of silver film 2.

[0017] The present invention provides an insulated inflatable sleeping pad with silver film. The three layers of silver film form a multi-reflective barrier, which effectively blocks the loss of heat radiation. The protective film 3 serves as a spacer layer, which not only fixes the position of the silver film 2, but also enhances the pressure resistance of the sleeping pad through its high elasticity, preventing deformation after inflation.

[0018] In one possible implementation, the silver film 2 has openings, with the openings in the upper and lower silver films aligned, and the openings in the middle silver film offset from those in the upper and lower silver films. The offset openings in the middle layer disrupt the heat radiation path, increase the number of heat reflections, and further improve the heat preservation efficiency.

[0019] In one possible implementation, a plurality of first weld points 41 are provided between the two protective films 3. The first weld points 41 are located within the openings of the middle silver film, and the first weld points 41 connect the two protective films 3. The first weld points 41 fix the protective films 3 at the openings of the middle silver film, preventing interlayer slippage and ensuring structural stability.

[0020] In one possible implementation, a second weld point 42 is provided between the protective film 3 and the inner surface of the outer layer film 1 of the sleeping mat. The second weld point 42 is located within the openings of the upper silver film and the lower silver film. The second weld point 42 integrates the outer layer film with the inner layer structure, preventing the outer layer film from expanding and separating during inflation.

[0021] In one possible implementation, the openings on the silver film 2 are oblong. The rounded edges reduce stress concentration and lower the risk of fatigue cracking of the silver film 2 due to repeated inflation and deflation.

[0022] In one possible implementation, the protective film is a TPU film or a plastic film. TPU film or silver film has good structural strength, which can stably fix the position of the silver film and improve the overall stability of the inflatable sleeping pad.
