DETAILED DESCRIPTION OF THE INVENTION

[0050] The technical solutions in the embodiments of the invention are clearly and completely described below in conjunction with drawings in the embodiments of the invention. Obviously, the embodiments described below are merely illustrative ones, and are not all possible ones of the invention. All other embodiments obtained by those ordinarily skilled in the art based on the following ones without creative labor should also fall within the protection scope of the invention.

[0051] Embodiment 1 illustrates a low-resilience, compressible and automatically-formed mattress. As shown in FIGS. 1-5, the low-resilience, compressible and automatically-formed mattress includes an upper composite fabric 1, a low-resilience filamentous mattress body 2, a lower composite fabric 3 and an air nozzle 4; [0052] each of the upper composite fabric 1 and the lower composite fabric 3 is formed by a breathable fabric layer 5 located at the top, a plastic sealing layer 6 combined with the breathable fabric layer 5 and located in the middle, and a thin sponge transition layer 7 combined with the plastic sealing layer 6 and located at the bottom; [0053] the low-resilience filamentous mattress body 2 is a filament-wound mattress body and provided with voids spreading all over the low-resilience filamentous mattress body 2; [0054] after the upper composite fabric 1 is glued on an upper surface of the low-resilience filamentous mattress body 2 and the lower composite fabric 3 is glued on a lower surface of the low-resilience filamentous mattress body 2, edges are sealed to form a main sealed air chamber 81, and the air nozzle 4 is arranged on the main sealed air chamber 81; [0055] after the air nozzle 4 is turned on, the low-resilience filamentous mattress body 2 is able to prop up the upper composite fabric 1 to suck air automatically to form the mattress.

Synergy Effect of the Low-Resilience Filamentous Mattress Body and the Composite Fabrics:

[0056] The breathable fabric layer is located at the top of the composite fabric, is in direct contact with the human body and is soft and comfortable, thus providing a good sense of touch and improving sleep comfort; and the breathable fabric layer also has certain abrasion resistance and breathability to guarantee the durability and air circulation of the surface of the mattress, thus avoiding stuffiness and discomfort for users.

[0057] The plastic sealing layer is located in the middle and plays a key role in realizing solid combination between upper and lower layers and sealing the air chamber. Synthetic rubber has a good glue affinity and adhesiveness and may firmly glue together the breathable fabric layer and the thin sponge transition layer. The synthetic rubber also has good elasticity and flexibility, can deform properly when bearing the pressure from the human body to provide certain buffer and support force, and can also guarantee the shape stability to maintain the overall structure of the mattress. In addition, the synthetic rubber has good sealing performance and can effectively prevent gas in the main sealed air chamber from leaking to ensure the sealing performance of the mattress.

[0058] The thin sponge transition layer is located at the bottom and mainly functions for buffering and transition. Thin sponge has certain elasticity and softness and can further improve the comfort and flatness of the mattress to support the human body more gently. Moreover, the thin sponge transition layer can well connect the composite fabric and the low-resilience filamentous mattress body and eliminate a possible unevenness or hardness difference between the composite fabric and the low-resilience filamentous mattress body to make the structure of the whole mattress more compact and stable, thus improving the overall performance of the mattress.

[0059] The low-resilience filamentous mattress body is a filament-wound mattress body, and the filaments with a fibrous characteristic have a good glue affinity to enable the upper composite fabric, the lower composite fabric and the low-resilience filamentous mattress body to be tightly combined with glue. Such a solid combination with glue ensures that different layers of materials are not prone to separation and adhesive failure during long-term use, thus guaranteeing the stability and integrity of the overall structure of the mattress. The filaments are thin, long, soft and flexible, are intertwined to form the stable mattress body, can provide good sleep experience for users, and can also maintain good structural performance when bearing the weight of the human body and various external forces, thus prolonging the service life of the mattress. The mattress body is a filament-wound structure, which makes the mattress body loose and have a large number of voids inside.

[0060] The low-resilience filamentous mattress body and the composite fabrics work together to endow the automatically-formed mattress with the sleep experience of common mattresses and the ease of storage and allow the mattress to be quickly inflated to be formed automatically without external force.

[0061] Breathability: the breathable fabric layer has good breathability.

[0062] Uniform support: the low-resilience filamentous mattress body, as a main component for providing uniform support, is confined in a specified space of the main sealed air chamber, with the upper surface and the lower surface being glued on the composite fabrics, which seems that the whole mattress is full of straps, such that after the mattress is inflated, the surface of the mattress is flat indeed and uniformly supports the human body, the body pressure is effectively dispersed, pressure points on different parts of the human body are reduced, and the comfort is improved; and the low-resilience, compressible and automatically-formed mattress has the sleep experience of conventional mattresses.

[0063] Ease of storage: the low-resilience filamentous mattress body is a filament-wound structure, and the looseness and numerous voids brought by the filament-wound structure are of great advantage for storage; the low resilience of the low-resilience filamentous mattress body allows for a smaller filament diameter and a large clearance, such that the mattress may be ultimately compressed more easily. The mattress may be smoothly stored in a narrow suitcase, at the corner of a cabinet and in the trunk of an automobile, and the convenience and flexibility in use are greatly improved.

[0064] Automatic formation: when used, the mattress is spread on the ground or in other places, the air nozzle 4 is turned on, and the low-resilience filamentous mattress body is relieved from a compressed state; when the composite fabrics are propped up with a low resilience, a negative pressure is produced in the main sealed air chamber, air enters the main sealed air chamber from the outside until the air pressure in the main sealed air chamber comes into balance with the air pressure outside the main sealed air chamber, and at this moment, the mattress is formed automatically; then, the air nozzle 4 is turned off, and the mattress may be used normally without extra inflation. The main sealed air chamber may be further inflated with the mouth, an air pump or an automatic inflation structure to satisfy personal requirements for the firmness of the mattress. In this embodiment, the main sealed air chamber is further inflated via the air nozzle 4.

[0065] The low-resilience, compressible and automatically-formed mattress has the sense of security of conventional mattresses: in the aspect of structure, the low-resilience filamentous mattress body is a filament-wound structure and tightly glued with the upper and lower composite fabrics. The glue affinity of fibers of the filaments ensures that the low-resilience filamentous mattress body is firmly combined with the composite fabrics formed by the breathable fabric layer, the plastic sealing layer and the thin sponge transition layer to form a stable structure. Such a tight connection ensures that there are no loose or deformable portions in the mattress, and all layers fit each other as closely as conventional mattresses, thus avoiding a sense of emptiness caused by shaking of internal structures. When a user lies on the mattress, the body pressure of the user will be uniformly dispersed on the whole tightly glued mattress structure, and a sense of unease caused by empty regions due to the fluidity of gas and the lack of sufficient constraints of internal structure of conventional air mattresses is avoided. The filament-wound structure may deform properly according to the body curve and the pressure distribution to provide support force fitting the body. Compared with conventional air mattresses that provide support merely by means of gas, the support based on solid filamentous materials is firmer and more solid. Although the conventional air mattresses can provide buoyant support when full of gas, the gas will flow quickly to be redistributed once the human body moves, leading to an instantaneous loss of support or nonuniform support, and users will feel unstable and unsecure. In dynamic use, the filamentous mattress body of the mattress maintains stable support by virtue of its structural tensity and elasticity, thus providing a constant sense of security for users.

[0066] Embodiment 1 systematically solves the technical problems in the background art.

[0067] (1) The invention solves the technical problem that existing air mattresses restrain the expansion of the air chamber by means of straps or support pillars, and the number and strength of the straps and the ease of storage cannot be balanced, leading to a frequent occurrence of bulges and breakage of the straps.

[0068] Replacement of strap constraint with distributed solid support: the low-resilience filamentous mattress body adopts a filament-wound grid structure, is provided with voids spreading all over the mattress body and forms a three-dimensional support framework. Compared with linear traction of traditional straps, such a structure divides the air chamber into micro support cells by means of distributed support based on numerous fiber nodes to directly prevent partial overexpansion of gas. After the mattress is inflated, the gas pressure uniformly acts on the grid structure, and the surface of the mattress is directly supported by the solid framework and is be kept flat without straps, such that bulges caused by a deficiency or failure of straps are fundamentally avoided.

[0069] Synergic sealing and improvement in tensile strength of the composite fabrics: the plastic sealing layer of the upper/lower composite fabric has high tensile strength and good sealing performance, replaces a traditional edge reinforcement design and restrains partial tensile deformation of the fabric caused by air pressure. The thin sponge transition layer fills in an interface gap between the fabric and the filamentous mattress body, eliminates stress concentration and avoids adhesive failure or breakage. The shape stability of the air chamber no longer relies on straps, and force is uniformly borne by means of the structural strength of materials.

[0070] (2) The invention solves the problem of the conflict between the flexible constraint of straps and the demand for load-bearing rigidity, that is, the invention solves the technical problems of sagging in certain parts, bulges on the edge and surface shaking caused by gas migration resulting from nonlinear deformation of straps, as elastic materials, under pressure.

[0071] Conversion from a support pattern based on traction of a limited number of force points to a support pattern based on force points densely distributed all over the mattress: when the human body applies a pressure to the mattress, the filamentous structure absorbs the pressure by means of plastic deformation of low-resilience materials rather than gas compression or strap stretching. Such a characteristic allows the deformation of a region under pressure to be uniformly transmitted by slight deformation of fiber nodes, thus preventing the migration of gas to a non-load-bearing region.

[0072] Improvement on the dynamic response ability: the grid structure of the filamentous mattress body imposes a three-dimensional constraint on the air chamber, and under the condition of a dynamic load such as turn-over of the body, an instantaneous pressure produced, for example, when users turn over, is quickly dispersed by means of the fiber nodes rather than the elastic resilience of straps, such that the amplitude of surface shaking is significantly reduced, and the stability of the mattress is close to the stability of conventional mattresses.

[0073] (3) The invention solves the problem of surface unevenness and shaking caused by the nonlinearity of gas, that is, the invention solves the technical problem that in a case where gas is used as a support medium, the gas will flow horizontally due to the redistribution of pressure when the mattress is under pressure, and traditional straps cannot control the gas flow in the mattress, leading to a lag in response.

[0074] Grid-based constraint of gas flow: an interstitial network of the filamentous mattress body divides the main sealed air chamber into numerous micro air chambers, and the gas flow is limited by fiber interspaces. When the human body applies a pressure to the mattress, the pressure produced by slight compression of gas is transmitted by fiber nodes, and the gas will not flow horizontally and freely, such that the formation of a dynamic pressure gradient is restrained. The filamentous structure plays a key role in bearing loads, and the gas merely functions as an auxiliary buffer medium. Even if the gas flows slightly, the gas flow will be quickly attenuated by the fiber interspaces to prevent an obvious pressure difference, thus eliminating surface unevenness and shaking caused by gas migration. By adopting such a design, the rigidity of the mattress is determined jointly by the initial pressure of gas and the filamentous structure rather than merely by the gas pressure, a nonlinear pressure-deformation relation is converted into a linear pressure-deformation relation, and responses better fit movements of the human body.

[0075] (4) The invention solves the problem of imbalance between support rigidity and physical comfort, that is, the invention solves the technical problem that the arrangement of support pillars in air mattresses improves partial rigidity, but sacrifices flexible fit of the air mattresses.

Balance Between Low Resilience and Comfort of the Grid Structure:

[0076] The filamentous mattress body adopts low-resilience materials and has both the function of support and the characteristic of flexible fitness: a grid framework formed by winding filaments provides basic structural strength and avoids sagging caused by the lack of gas pressure of traditional mattresses; the low-resilience materials with slow deformation fit the body curve and disperses the body pressures, such that the defect of single-point rigid support of support pillars is overcome.

[0077] (5) The invention solves the problem of decline in sleep quality caused by sleep experience defects, that is the invention solves the problem of sleep fragmentation caused by nonuniform body pressure and shaking resulting from a mismatch between the support principle of air mattresses and human sleep demands.

[0078] Fundamental change in the support principle: traditional air mattresses rely on the compressibility of gas and the elastic coupling of straps, while the mattress in Embodiment 1 adopts a support system with the grid filament structure as a main structure and gas as an auxiliary buffer, the pressure transmission mechanism is changed from nonlinear flow of gas into linear deformation of materials, and the support pattern of the mattress is the same as the support pattern of conventional mattresses. Specifically:

[0079] Uniform distribution of body pressure: under the combined action of the grid network and low resilience of the filamentous mattress body, the body pressure is uniformly dispersed by means of fiber nodes to prevent sagging in the middle and bugles on the edge of traditional air mattresses.

[0080] Dynamic stability: the quick response of the solid structure restrains surface shaking, reduces a sudden change of pressure when the sleep position is changed, and reduces stimuli to sympathetic nerves.

[0081] Physiologically adaptive design of material and structure: the breathable fabric layer of the composite fabrics is skin-friendly and breathable, the thin sponge transition layer functions as a buffer against pressure, the plastic sealing layer functions for maintaining the shape, and the composite fabrics and the filamentous mattress body construct a three-layer structure, including a contact layer, a buffer layer and a support layer, similar to the structure of conventional mattresses, and the mattress comprehensively satisfies human sleep demands in the sense of touch, pressure distribution and dynamic response; and the slow deformation of the low-resilience materials reduces vibration transmission when users turn over, creates a stable sleep environment, and solves, in principle, the problem of poor sleep experience caused by the support pattern of air mattresses.

[0082] (6) The invention systemically resolves the key contradiction

[0083] The key contradiction in the background art is the intrinsic conflict between flexible constraint support and dynamic uniform load-bearing, which roots in the use of elastic materials for indirect control of gas expansion in the prior art.

[0084] The mattress provided by the invention is innovated in the following aspects: [0085] Shape stability: the three-dimensional grid structure directly bears the pressure in the air chamber and keeps the surface flat without straps; [0086] Uniform support: the linear deformation of the low-resilience materials and pressure dispersion of the grid network realize a uniform distribution of the body pressure [0087] Dynamic response ability: the quick deformation response of the filaments eliminates the lag of gas flow and restrains shaking.

[0088] The sense of security of conventional mattresses: the filament-wound mattress body is tightly glued with the fabrics, such that the structure is stable, and solid support is realized.

[0089] Such an innovation is not merely a technical improvement, but a systematic breakthrough in low-resilience filaments, reticulate voids and support principle, fundamentally breaks through the performance bottleneck under the constraint of lightweight of existing air mattresses, allows air mattresses to have for the first time the sleep experience similar to that of conventional mattresses, reserves the key advantages of ease of storage and portability, and realizes automatic formation of the mattress.

[0090] Embodiment 2: This embodiment illustrates one low-resilience filamentous mattress body. As shown in FIGS. 1-2, by decreasing a filament diameter to reduce the use of filaments, the low-resilience filamentous mattress body 2 has a lower weight and resilience, still allowing for automatic formation and ultimate storage of the mattress.

[0091] In this embodiment, under the condition of maintaining the stability of the filament-wound structure, the filament diameter is decreased to greatly reduce the use of filaments in unit volume, and the load-bearing uniformity, dispersibility, glue affinity and low resilience of the filaments are reserved. The smaller filament diameter allows for better deformability of fibers in a compressed state and ultimate storage, and the weight of the mattress is equivalent to that of a conventional air mattress of the same size; the lightweight design reduces the overall weight of the mattress and makes the mattress portable; and the low resilience may still drive the main sealed air chamber to suck air automatically to realize automatic formation of the mattress.

[0092] Embodiment 3: This embodiment illustrates another low-resilience filamentous mattress body. As shown in FIGS. 1-2, by increasing a winding clearance of filaments to reduce the use of filaments, the low-resilience filamentous mattress body 2 has a lower weight and resilience, still allowing for automatic formation and ultimate storage of the mattress.

[0093] In this embodiment, by adjusting winging process parameters such as the winding angle and distance to increase the winding clearance, such that under the condition of guaranteeing support strength of the mattress body, the use of filaments is greatly reduced, and the low resilience of the filaments is maintained. The greater clearance reduces the overall rigidity of the filaments and improves the deformability of fibers in a compressed state to realize ultimate storage; the size of the mattress is one third the storage size of a sponge mattress body of the same size, and the weight of the mattress is close to the weight of conventional air mattress; the lightweight design reduces the overall weight and storage size of the mattress and makes the mattress portable; and the low resilience may still drive the main sealed air chamber to suck air automatically to realize automatic formation of the mattress.

[0094] In Embodiments 2 and 3, by structural optimization (decreasing the filament diameter/increasing the clearance), a breakthrough is made in lightweight design, low resilience and ease of storage; meanwhile, by means of the glue affinity of the filaments and the stability of the wound structure, the mattress still has an automatic formation, a storage function and sleep experience the same as that of conventional mattresses after the use of materials is reduced.

[0095] Embodiment 4: This embodiment illustrates how to select the breathable fabric layer and the plastic sealing layer. As shown in FIG. 1: [0096] the breathable fabric layer 5 at least includes at least one of a cloth fabric layer and a flocked fabric layer.

[0099] Embodiment 5: This embodiment illustrates the thin sponge layer. As shown in FIG. 1, the thin sponge transition layer 7 is a thin sponge layer and has a thickness of 0.2-1 cm. Such a thickness guarantees soft touch and structural support, eliminates a hardness difference between the fabric and the mattress body and improves fitness and comfort; the thin structure reduces the use of materials, the overall thickness of the mattress is controllable, and the mattress occupies a small space when compressed to be stored, and is easy to store; and the appropriate thickness ensures that the upper and lower composite fabrics are in close fit with the filamentous mattress body, improves interlayer connection stability and avoids adhesive failures or separation of different layers.

[0100] Embodiment 6: This embodiment illustrates the filament diameter. As shown in FIGS. 1-2, the filament diameter is 0.2-0.5 mm. Such a filament diameter guarantees both the stability and softness of the filament-wound structure, prevents sagging when the mattress supports the human body, and provides an appropriate resilience force to drive the mattress to be formed automatically; by setting an appropriate filament dimeter range, unnecessary material consumption is reduced, the weight of the mattress is moderate, and both portability and durability are guaranteed; and the proper filament diameter allows for a suitable clearance between filaments, the mattress deforms easily to be stored when compressed, and when the mattress is decompress, the fabrics may be quickly propped up to produce a negative pressure to suck air to ensure smooth and automatic deformation of the mattress.

[0101] Embodiment 7: This embodiment illustrates a press type firmness-adjustable mattress. As shown in FIGS. 1-7, the press type firmness-adjustable mattress includes the low-resilience, compressible and automatically-formed mattress, an automatic inflation structure 9 and a check valve 95 arranged between the low-resilience, compressible and automatically-formed mattress and the automatic inflation structure 9, wherein air unidirectionally enters the low-resilience, compressible and automatically-formed mattress; and by pressing the automatic inflation structure 9, the mattress is further supplemented with air quickly to adjust firmness of the mattress.

The press type firmness-adjustable mattress is compressible, easy to store and automatically formed, allows for firmness adjustment by pressing and has the sleep experience of conventional mattresses.

As shown, the press type firmness-adjustable mattress further includes an additional sealed air chamber 82, the main sealed air chamber 81 and the additional sealed air chamber 82 communicate with each other by means of an air passage and form the whole mattress with two sealed air chambers, and the automatic inflation structure 9 is arranged on the additional sealed air chamber 82.

[0104] In this embodiment, the main sealed air chamber 81 and the additional sealed air chamber 82 communicate with each other by means of the air passage and form an integrated support structure, such that the air pressures in the air chambers are dynamically balanced the body pressure is dispersed, and the overall support uniformity of the mattress is improved; the automatic inflation structure 9 is arranged on the additional sealed air chamber 82 to be integrated with the mattress, such that the mattress looks harmonious and aesthetic, and the firmness of the mattress may be controlled more accurately; and air chambers of the double-chamber structure are flexibly connected by means of the air passage, such that wrinkles or damage is unlikely to occur when the mattress is folded, thus improving durability.

[0105] Embodiment 9: This embodiment illustrates the automatic inflation structure.

[0108] In this embodiment, the unidirectional inflation valve 93 is matched with the air vent 94 of the high-resilience breathable structure 92, air is quickly sucked from the outside when the high-resilience breathable structure 92 is pressed, and the unidirectional inflation valve 93 is automatically turned off to prevent air leakage when the high-resilience breathable structure 92 is released, such that the air supplement process is smooth; and the high-resilience breathable structure 92 deforms to squeeze gas when pressed and quickly restores when released, such that the air supplement efficiency is high.

[0109] Embodiment 10: This embodiment illustrates the high-resilience breathable structure.
