Abstract
Description
Technical Field
[0001] This utility model relates to the field of daily necessities technology, and in particular to an adjustable mattress. Background Technology
[0002] Traditional mattresses are mainly divided into two types: spring mattresses and airbag mattresses. Spring mattresses provide support through a metal spring system, which provides good support, but the firmness is fixed and cannot meet the personalized needs of different users. Airbag mattresses, on the other hand, adjust the firmness by inflating and deflating air, but due to the lack of a rigid support structure, they are prone to problems such as localized collapse and uneven distribution of support after long-term use.
[0003] Therefore, existing mattresses need to be improved to achieve intelligent adjustment of firmness while avoiding sagging.
[0004] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] To achieve the above objectives, this utility model provides an adjustable mattress, comprising two spaced-apart airbags, an inflation / deflation pump connected to the two airbags, and a spring layer located between the two airbags.
[0007] Optionally, the airbag cushion includes an airbag body surrounding the airbag cavity and a deformation-resistant component located inside the airbag body;
[0008] The anti-deformation component is connected to each wall of the airbag cavity to suppress the outward arching deformation of the airbag body after inflation.
[0009] Optionally, the anti-deformation component includes a plurality of first spacers arranged at intervals and in parallel, and a plurality of second spacers arranged at intervals and in parallel;
[0010] The first and second spacers intersect to divide the airbag cavity into several independent air chambers.
[0011] Optionally, the first and / or second spacers are provided with a plurality of vent holes that connect two adjacent independent air chambers.
[0012] Optionally, the inflation / deflation pump is connected to one of the independent air chambers at the edge location.
[0013] Optionally, the independent air chambers in the middle position are rhomboid in shape; the independent air chambers at the edge positions are triangular in shape.
[0014] Optionally, the anti-deformation component is connected to the airbag body via a stitch, and a sealant layer is applied to the stitch.
[0015] Optionally, the deformation-resistant components are ultrasonically welded to the airbag body.
[0016] Optionally, both the deformation-resistant component and the airbag body have a moisture-absorbing PU coating on their outer surfaces.
[0017] Optionally, a mattress cover is also included to enclose the two airbags and the spring layer, wherein the mattress cover has an installation port for the air pump to pass through at the location corresponding to the position of the air pump.
[0018] The beneficial effects of this utility model are as follows: It provides an adjustable mattress in which a spring layer is set between two spaced upper and lower double-layer air cushions to form a composite support structure.
[0019] Among them, the spring layer, as a rigid skeleton, provides basic resistance to deformation and maintains the integrity of the support plane when the airbag is completely depressurized, thus overcoming the creep and collapse defects of traditional airbag beds.
[0020] The upper and lower airbags are supported by an air pump to adjust the firmness. Users can adjust the internal pressure of the airbags to the required size according to their own needs, thereby obtaining a customized firmness support experience.
[0021] Therefore, the adjustable mattress provided by this utility model can achieve intelligent adjustment of firmness while avoiding the problem of sagging. Attached Figure Description

[0038] This utility model provides an adjustable mattress suitable for home, medical care and other scenarios. Through the composite support structure of spring layer and adjustable air bladder and intelligent inflation and deflation system, it solves the problems of traditional mattresses such as non-adjustable firmness, easy collapse and insufficient support and comfort, and achieves personalized sleep support and long-term use stability.
[0039] See Figures 1-3 In this embodiment, the adjustable mattress includes two spaced-apart airbags 1, an inflation / deflation pump 2 connected to the two airbags 1, and a spring layer (not shown in the figures) located between the two airbags 1.
[0040] The adjustable mattress also includes a mattress cover 3 that covers the two air cushions 1 and the spring layer, wherein the mattress cover 3 has an installation port for the air pump 2 to pass through at the position corresponding to the position of the air pump 2.
[0041] Optionally, the air pump 2 has a built-in wireless communication module to connect with terminals such as mobile phones, allowing users to control the air pump 2 for air inflation and deflation operations via a designated APP.
[0042] Of course, a momentary inflation button and a momentary deflation button can also be installed on the outer surface of the inflation / deflation pump 2, so that inflation / deflation operations can be performed by pressing the buttons.
[0043] The adjustable mattress provided by this utility model has a composite support structure formed by a spring layer between two spaced upper and lower double-layer airbag pads 1:
[0044] Among them, the spring layer, as a rigid skeleton, provides basic resistance to deformation and maintains the integrity of the support plane when the airbag is completely depressurized, thus overcoming the creep and collapse defects of traditional airbag beds.
[0045] The upper and lower airbags 1 are supported by an inflation and deflation pump 2 to adjust the hardness. Users can adjust the internal pressure of the airbags 1 to the required size according to their own needs, thereby obtaining a customized hardness support experience.
[0046] Therefore, the adjustable mattress provided by this utility model can achieve intelligent adjustment of firmness while avoiding the problem of sagging.
[0047] Optionally, the airbag pad 1 is made of butyl rubber. Butyl rubber has good airtightness, good ozone resistance, chemical corrosion resistance, flexural resistance, and heat aging resistance.
[0048] In this embodiment, the airbag cushion 1 includes an airbag body 101 surrounding the airbag cavity and an anti-deformation component 102 located inside the airbag body 101.
[0049] The anti-deformation component 102 is connected to each wall surface of the airbag cavity to suppress the outward arching deformation of the airbag body 101 after inflation.
[0050] Optionally, the anti-deformation component 102 can be made of a flexible polymer material with high elasticity and bending resistance. Specifically, the following solutions can be adopted:
[0051] ① High-strength TPU (thermoplastic polyurethane): It has good resilience and creep resistance, and is suitable for occasions that require repeated deformation;
[0052] ② Composite fabric structure: It is composed of polyester or nylon base fabric and silicone / rubber coating, which combines the flexibility of fabric and the interfacial adhesion of coating.
[0053] ③Aging-resistant rubber materials: such as butyl rubber or chloroprene rubber, which are particularly suitable for environments requiring moisture and oxidation protection;
[0054] ④ Modified PVC material: Improved flexibility at low temperatures through plasticizing treatment.
[0055] Generally, without the anti-deformation component 102, after the airbag cavity is inflated, all surfaces of the airbag body 101 will exhibit a shape that bulges outward from the center. This not only affects the aesthetics of the mattress, but also causes the top surface of the airbag body 101 to have insufficient flatness, resulting in a decrease in the user's sleep comfort.
[0056] After the anti-deformation component 102 is added, the anti-deformation component 102 will pull the various walls of the airbag cavity inward inside the airbag body 101, thereby suppressing the outward arching deformation of the airbag body 101 after inflation, so that the various surfaces of the airbag body 101 maintain a planar structure as much as possible, thereby improving aesthetics and sleep comfort.
[0057] The anti-deformation component 102 includes a plurality of first spacers 1021 arranged at intervals and in parallel, and a plurality of second spacers 1022 arranged at intervals and in parallel;
[0058] The first partition 1021 and the second partition 1022 intersect to divide the airbag cavity into several independent air chambers 103.
[0059] In this embodiment, the first spacer 1021 and / or the second spacer 1022 are provided with a plurality of vent holes connecting two adjacent independent air chambers 103. Optionally, both spacers are mesh structures to maximize inflation and deflation efficiency.
[0060] In this embodiment, the inflation / deflation pump 2 is connected to one of the independent air chambers 103 at the edge position. Since each pair of adjacent independent air chambers 103 is connected through a vent hole, the inflation / deflation pump 2 can connect to all independent air chambers 103 through each vent hole, thereby performing inflation / deflation operations on all independent air chambers 103.
[0061] Optionally, the independent air chambers 103 in the middle position are rhomboid in shape; the independent air chambers 103 at the edges are triangular in shape. The design of the independent air chambers 103 with the central rhomboid shape and the edges being triangular optimizes the distribution of support force and improves local support comfort.
[0062] In this embodiment, the anti-deformation component 102 is connected to the airbag body 101 via a stitch, and a sealant layer is applied to the stitch. The stitched connection greatly improves the connection strength between the spacer and the airbag body 101, making it less prone to breakage. After stitching, air leakage is likely at the needle holes, hence the sealant layer is used for sealing.
[0063] In some other embodiments, the anti-deformation component 102 and the airbag body 101 are ultrasonically welded, which can effectively connect them without leakage. Both the anti-deformation component 102 and the airbag body 101 are coated with a moisture-absorbing PU coating, which is not only environmentally friendly but also has good wear resistance. Furthermore, the airbag body 101 is made of butyl rubber, and since the interior of the airbag body 101 is dry, the inner surface does not need to be coated with a moisture-absorbing PU coating.
[0064] In summary, the adjustable mattress provided in this embodiment has the following advantages:
[0065] ① Spring layer composite support: A spring layer is set between the two airbag pads 1 as a rigid frame. When the airbags are depressurized, the integrity of the support plane is maintained, avoiding the collapse problem of traditional airbag mattresses.
[0066] ② Anti-deformation component 102 suppresses outward arching: The anti-deformation component 102 is connected to the wall of the airbag cavity to suppress outward arching deformation after inflation, keep the airbag surface flat, and improve comfort and aesthetics.
[0067] ③ Separating independent air chambers 103 by partition strips: The airbag cavity is divided into multiple independent air chambers 103 by intersecting first partition strips 1021 and second partition strips 1022, which enhances structural stability and optimizes support uniformity.
[0068] ④ Ventilation hole / mesh strip design: Ventilation holes or a mesh structure are set in the strip to improve inflation and deflation efficiency and ensure that the pressure of each independent air chamber 103 is adjusted synchronously.
[0069] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
