A wire-drawing inflatable air mattress and its manufacturing method

Abstract

This invention discloses a PVC-coated fabric inflatable mattress and its manufacturing method. The mattress includes a hollow, sealed mattress body with a main airbag chamber. A tension layer, made of PVC-coated fabric, is installed within the main airbag chamber. The upper and lower sides of the tension layer are made of PVC-coated polyester fabric, with densely packed filaments between the sides. The two ends of the tension layer are connected to the side walls of the main airbag chamber. After the main airbag chamber is inflated, the tension layer tightens and pulls the upper and lower walls of the mattress body, forming multiple taut, pressure-resistant blocks. When a pressure-resistant block is compressed, the surrounding uncompressed pressure-resistant blocks pull outwards through the tension of the tension layer, offsetting some of the pressure and significantly reducing localized depressions. A secondary airbag chamber is connected to the main airbag chamber through air holes on the chamber walls. After inflation, the secondary airbag chamber protrudes from the mattress surface, enhancing support stability and providing anti-slip edges. This invention has a reasonable structural design, dispersing localized pressure to the whole through the tension network of the internal fabric, effectively solving the problem of easy depressions in traditional inflatable mattresses.

Description

Technical Field

[0001] This invention relates to the field of air mattress technology, specifically to a wire-drawing inflatable air mattress and its manufacturing method. Background Technology

[0002] Existing air mattresses typically use a single-layer air chamber structure. They work by inflating a closed cavity with air, using air pressure to support the entire mattress. This structure is lightweight and easy to store and carry, making it widely used in camping, temporary accommodation, and as a home backup.

[0003] However, traditional single-layer airbag mattresses have significant performance defects in actual use. Because they rely entirely on air pressure for support, when a person lies down, the body weight creates localized pressure on the surface of the airbags, causing the pressure-bearing areas to sink significantly downwards, while the surrounding unpressurized areas retain their original height, forming noticeable "indentations." This localized collapse not only makes the mattress surface uneven but also forces the spine into a curved position, which can easily lead to lower back pain and seriously affect sleep quality with long-term use.

[0004] To address this issue, some products enhance support by increasing airbag thickness or inflation pressure. However, this often results in an overly hard surface and reduced comfort, and high-pressure inflation places higher demands on the sealing and durability of the materials. Other products incorporate simple internal straps or partitions, but due to structural design limitations, these straps are mostly point-like or linear connections, failing to form an effective overall tension network. This limits their ability to disperse localized downward pressure, and they still struggle to prevent denting.

[0005] Furthermore, traditional air mattresses typically have weak edge supports, making it easy for users to slip when turning over, reducing safety and comfort. At the same time, existing products still have significant room for improvement in areas such as inflation / deflation efficiency, internal structural durability, and ease of production and assembly.

[0006] Therefore, how to provide an air mattress that is lightweight, provides high rigidity support, effectively resists local indentation, and is comfortable and durable has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a wire-drawing inflatable air mattress, whose main advantage lies in the fact that when subjected to pressure, the pressure-resistant surface becomes smaller, achieving an effect comparable to traditional spring mattresses, thus effectively solving the problems existing in the prior art.

[0008] The objective of this invention is achieved through the following technical solution: A wire-drawing inflatable air mattress includes a mattress body with a hollow main air chamber. The main air chamber is inflated to make the mattress body stable. This inflated state is the usable state. In the deflated state, the mattress body can be folded and stored. The main air chamber has a tension layer that is connected to the main air chamber, allowing air to move freely between them. Inflating the main air chamber also inflates the tension layer. The two ends of the tension layer are connected to the side walls of the main air chamber. When the main air chamber is fully inflated, the tension layer is taut and tightens the two walls connected to it, forming multiple taut pressure-resistant blocks on the two walls. When one of the pressure-resistant blocks is subjected to pressure, the surrounding non-pressure-resistant blocks will pull outwards to reduce the degree of inward indentation of the pressure-resistant blocks and the overall indentation of the bed body surface. In other words, when a human torso / object comes into contact with a pressure-resistant block, the pressure-resistant blocks that are not in contact with the human torso / object can tighten the pressure-resistant blocks that are in contact with the human torso / object, reducing the degree of deformation of the pressure-resistant blocks that are in contact with the human torso / object, thereby enhancing the pressure resistance of the upper surface of the bed body and giving the bed body a superior support effect.

[0009] In one embodiment, the tensioning layer is made of PVC filament fabric, which has high strength and tear resistance. It becomes rigid after inflation and can be rolled up and stored after deflation without affecting the storage effect of the bed body. The upper and lower sides of the PVC filament fabric are made of PVC coated polyester fabric. PVC coated polyester fabric is a functional composite material that combines polyvinyl chloride (PVC) coating with high-strength polyester base fabric. It combines the strength and toughness of polyester with the waterproof and weather-resistant properties of PVC. As the side where the tensioning layer is attached to the bed body, it can ensure that the bonding surface formed by the two is strong and durable. There is a filament between the two PVC coated polyester fabrics. The filament is made of polyester monofilament. The PVC coated polyester fabric is connected to the top and bottom walls of the main airbag chamber. In the inflated state, the filament becomes a rigid PVC filament fabric plate, and at the same time, the top and bottom walls of the main airbag chamber are assimilated into a rigid plate.

[0010] In one embodiment, the bed body is further provided with a secondary airbag chamber, which surrounds the upper and lower sides of the main airbag chamber and is interconnected with the main airbag chamber. After inflation, the main airbag chamber and the secondary airbag chamber expand. The secondary airbag chamber is located on the upper and lower sides of the bed body and serves to stabilize the bed body when it is placed.

[0011] In one embodiment, the bed body is provided with a partition wall that divides the bed body into a main airbag chamber and a secondary airbag chamber, serving as a partition and limiting the maximum expansion volume of the bed body. This controls the shape of the bed body from the inside out. The partition wall is provided with air passage holes, through which the main airbag chamber and the secondary airbag chamber are connected. By controlling the size of the air passage holes, the sides of the partition wall can be connected to the inner wall of the bed body, thereby controlling the cross-sectional profile of the bed body and limiting its thickness.

[0012] In one embodiment, the middle of the bladder wall is provided with a clearance slot to avoid the side wall of the bed body, preventing the bladder wall from squeezing the side wall of the bed body when it expands outward. The bladder wall is arc-shaped and connected to the upper and lower walls of the bed body when the bed body is inflated. At the same time, the side of the slot will press against the side of the bed body, providing outward support to the side wall of the bed body, making it less likely to sink inward. The four corners of the bladder wall are chamfered. The chamfered surfaces do not contact the side wall of the bed body when the bed body is inflated, effectively avoiding the four side edges of the bed body.

[0013] In one embodiment, there is an angle between the top and bottom walls of the bladder wall and the top and bottom walls of the bed body. When the bed body is in an inflated state, the angle between the top and bottom walls of the bladder wall and the top and bottom walls of the bed body is V-shaped, and this V-shaped angle and the side wall of the bed body form a secondary airbag chamber. The side wall of the bed body is divided into a sandwich structure by the bladder wall, wherein the middle layer is the main airbag chamber, and the upper and lower sides of the main airbag chamber are secondary airbag chambers. After the bladder wall is connected to the side wall of the bed body, its cross-section is triangular, which makes the secondary airbag chamber structure stable.

[0014] In one embodiment, the air vents are arranged in pairs and mirror images of each other on the left and right sides of the chamfered surface. The auxiliary airbag chamber is provided with at least one set of air vents to ensure air intake efficiency.

[0015] In one embodiment, when the bed body is in an inflated state, the auxiliary airbag chamber protrudes from the upper and lower surfaces of the bed body. The auxiliary airbag chamber surrounds the top and bottom walls of the bed body, increasing the contact area between the auxiliary airbag chamber and the ground, and ensuring the stability of the bed body when placed.

[0016] In one embodiment, the side wall of the bed body is also provided with an exhaust valve and an inflation component, wherein the exhaust valve is used for rapid exhaust, and the inflation component is an electric air pump that does not require manual inflation.

[0017] Secondly, the present invention also provides a manufacturing process for a wire-drawn inflatable air mattress, comprising the following steps: S1 Wire Pulling Inspection: Flatten the PVC wire pull cloth and inspect the wire pull in the middle of the PVC wire pull cloth to ensure that there are no broken wires, no delamination, and no missing wires; S2 Top and Bottom Wall Fabrication and Composite: The top and bottom walls of the bed body are cut out, and the top and bottom walls of the bed body are pressed onto the top and bottom walls of the tension layer using high-frequency technology; The top and bottom walls of the bed body are made of PVC composite polyester (polyester) fabric. S3 Internal Capsule Wall Welding: The capsule walls are cut out and the upper and lower side walls of the capsule walls are connected to the back of the top and bottom walls of the bed body through high-frequency technology. The capsule wall material is polyvinyl chloride; S4 sidewall welding: The sidewalls of the bed body are cut out, and the sidewalls of the bed body are connected to the sidewalls of the top and bottom walls of the bed body through high-frequency technology. The side walls of the bed body are made of PVC composite polyester (polyester) fabric. S5 component assembly: Install exhaust valves and inflation components on the side wall of the bed body; S6 Finished Product Inspection: Conduct quality inspection on the installed bed body. Beneficial effects

[0018] 1. Superior support, comparable to a home mattress By utilizing the three-dimensional tension layer formed by the internal woven fabric, the bed surface is divided into multiple pressure-resistant blocks. When local pressure is applied, the surrounding blocks are pulled outward through the woven fabric, distributing the downward pressure to the entire bed surface and effectively resisting local indentation. This principle fundamentally solves the problem of "softness and collapse" in traditional air mattresses, making the bed surface firm and flat, greatly improving support rigidity, and providing healthy support for the spine.

[0019] 2. Zoned pressure resistance for a comfortable and stable feel. The pressure-resistant block at the top of the bed directly supports the human body, while the block below makes stable contact with the ground. The coordinated action of the upper and lower sections ensures both a comfortable fit to the body and the stability of the overall structure. In addition, the secondary air chambers surrounding the upper and lower surfaces not only enhance the overall stability of the bed, but the raised edges also effectively prevent rolling out of bed, improving the sense of security during sleep.

[0020] 3. Compact structure, combining durability and high efficiency. The design of the compartment walls and the avoidance slots ensures that the internal structure fits precisely after inflation, avoiding friction damage. The air vents enable rapid inflation and deflation between the main and auxiliary air chambers. The entire structure is made of high-strength PVC composite polyester fabric, which gives the bed excellent waterproof, wear-resistant and tear-resistant properties, greatly extending the product's service life.

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Example 1

[0029] Please see Figure 1-9 A type of inflatable air mattress includes a mattress body 1. The mattress body 1 is hollow, forming a main air chamber 2. The main air chamber 2 is provided with a tension layer 3, which is interconnected with the main air chamber 2, allowing air to move freely between them. The mattress body 1 is a hollow, sealed structure and is the basic load-bearing component of the air mattress. It is made of PVC composite polyester (polyester) fabric, which has waterproof, wear-resistant, and tear-resistant properties. The tension layer 3 is connected to the side walls of the main air chamber 2 at both ends. When the main air chamber 2 is filled with air, the tension layer 3 is tightened and stretched to the two walls connected to it, so that the two walls form multiple tight pressure-resistant blocks 4. When one of the pressure-resistant blocks 4 is under pressure, the pressure-resistant blocks 4 around it that are not under pressure will pull the pressure-resistant block 4 outward, reducing the degree to which the pressure-resistant block 4 sinks inward and reducing the degree of indentation of the overall surface of the bed body 1. In use: After the main air chamber 2 is inflated, the tension layer 3 and its filaments 6 form a three-dimensional support structure, which makes the top and bottom walls of the bed body 1 form multiple tension-resistant blocks 4. When a single tension-resistant block 4 is under pressure, the surrounding unpressurized tension-resistant blocks 4 pull the pressurized block outward through the tension of the tension layer 3, offsetting part of the pressure, significantly reducing the inward sinking of the pressurized block, thereby reducing the inward sinking of the overall surface of the bed body 1 and ensuring the rigidity of the support.

[0030] Preferably, the tension layer 3 is a PVC filament fabric, the upper and lower sides of the PVC filament fabric are PVC coated polyester fabric 5, the two PVC coated polyester fabrics 5 are connected by a filament 6, and the PVC coated polyester fabric 5 is connected to the top wall and bottom wall of the main airbag chamber 2.

[0031] By adopting the above technical solution, the tension layer 3 is set inside the main airbag chamber 2 and is made of PVC filament fabric. Among them: the top and bottom sides are PVC coated polyester fabric 5, and the middle is high-density polyester filament 6; The upper and lower ends of the tension layer 3 are fixedly connected to the side walls of the main airbag chamber 2. After the main airbag chamber 2 is inflated, the tension layer 3 is in a tense state and tightens the upper and lower walls of the bed body 1, so that the upper and lower walls form multiple independent tension and pressure-resistant blocks 4. The pressure-resistant block 4 located below the bed body 1 is in contact with the horizontal plane and resists pressure as a whole, while the pressure-resistant block 4 located above the bed body 1 is the side in contact with the human body and resists pressure only partially.

[0032] Preferably, the bed body 1 is also provided with a secondary airbag chamber 7, which surrounds the upper and lower sides of the main airbag chamber 2 and is interconnected with the main airbag chamber 2.

[0033] By adopting the above technical solution, the auxiliary airbag chamber 7 protrudes from the upper and lower surfaces of the bed body 1 after inflation, which not only enhances the support stability but also improves the comfort of use. At the same time, the horizontal height of the auxiliary airbag chamber 7 is higher than the height of the bed body 1, which can provide a boundary effect and play an interception role.

[0034] Preferably, the bed body 1 is provided with a dividing wall 8, which divides the bed body 1 into a main airbag chamber 2 and a secondary airbag chamber 7. The dividing wall 8 is provided with an air passage hole 9, and the main airbag chamber 2 and the secondary airbag chamber 7 are connected through the air passage hole 9.

[0035] By adopting the above technical solution, the main airbag chamber 2 and the auxiliary airbag chamber 7 can achieve free air circulation through the air holes 9 on the split chamber wall 8. When inflated, the two expand synchronously, and when deflated, the air can be quickly exchanged, improving the deflation efficiency. The split chamber wall 8 plays a separating role, dividing the bed body 1 into multiple chambers. During inflation, the airflow direction is as follows: Figure 9 As shown, the airflow enters the auxiliary airbag chamber 7 from the main airbag chamber 2 through the air passage 9; During exhaust, the air in the auxiliary airbag chamber 7 flows through the air passage 9 to the main airbag chamber 2, and then is discharged through the exhaust valve 13 provided on the side wall of the main airbag chamber 2.

[0036] Preferably, the middle part of the bladder wall 8 is provided with a clearance slot 10 for avoiding the side wall of the bed body 1. When the bed body 1 is inflated, the bladder wall 8 is arc-shaped and connected to the upper and lower walls of the bed body 1. At the same time, the side of the slot 10 will abut against the side of the bed body 1. The four corners of the bladder wall 8 are chamfered surfaces 11. The chamfered surfaces 11 do not contact the side wall of the bed body 1 when the bed body 1 is inflated.

[0037] By adopting the above technical solution, during the inflation process, the avoidance slot 10 is specifically designed to avoid the side wall of the bed body 1, ensuring that the compartment wall 8 can be precisely fitted with the bed structure after assembly, thus avoiding spatial interference. When the bed body 1 is in an inflated state, the bladder wall 8 naturally arcs and tightens the upper and lower walls of the bed body 1, achieving the effect of tightening the side of the bed body 1 from the inside. At the same time, the side of the avoidance slot 10 will tightly press against the side of the bed body 1, forming a support effect. The tightening and support interact to further ensure the shape of the bed body 1. The four corners are provided with chamfered surfaces 11. The chamfered surfaces 11 are designed with optimized curvature so that they will not come into contact with the side walls of the bed body 1 after the bed body 1 is fully inflated, effectively avoiding friction damage caused by compression.

[0038] Preferably, there is an angle 12 between the top and bottom walls of the bladder wall 8 and the top and bottom walls of the bed body 1. When the bed body 1 is in an inflated state, the angle between the top and bottom walls of the bladder wall 8 and the top and bottom walls of the bed body is V-shaped, and the V-shaped angle 12 and the side wall of the bed body 1 form a secondary air bladder chamber 7.

[0039] By adopting the above technical solution, an angle of 12 is preset between the top and bottom walls of the capsule wall 8 and the top and bottom walls of the bed body 1; The auxiliary airbag chamber 7 is constructed as follows: When the bed body 1 is fully inflated, under the action of the air pressure inside the airbag, the top wall of the airbag wall 8 will naturally form a regular V-shaped angle 12 with the top wall of the bed body 1. The top of the V-shaped angle 12 faces the main airbag chamber 2. The two side walls of the airbag wall 8 and the top wall of the bed body 1, and the bottom wall are the side walls of the bed body 1, together form a sealed auxiliary airbag chamber 7, so that the cross-sectional shape of the auxiliary airbag chamber 7 is triangular, ensuring that the auxiliary airbag chamber 7 has a stable air-containing space and support shape. The configuration of the lower auxiliary airbag chamber 7 is a mirror image of the configuration of the upper auxiliary airbag chamber 7.

[0040] Preferably, the air vents 9 are arranged in pairs and mirror images on the left and right sides of the chamfered surface 11, and the auxiliary airbag chamber 7 is provided with at least one set of air vents 9.

[0041] By adopting the above technical solution, air is opened on the split-cell wall 8 to realize air circulation between the main airbag chamber 2 and the auxiliary airbag chamber 7; preferably, they are arranged in pairs and mirrored on the left and right sides of the chamfered surface 11, and each auxiliary airbag chamber 7 is equipped with at least one set of air passages 9 to ensure uniform and efficient inflation / exhaust.

[0042] Preferably, when the bed body 1 is in an inflated state, the auxiliary airbag chamber 7 protrudes from the upper and lower surfaces of the bed body 2.

[0043] By adopting the above technical solution, the auxiliary airbag chamber 7 surrounds the upper and lower sides of the main airbag chamber 2 and is interconnected with the main airbag chamber 2; when the bed body 1 is in a fully inflated state, the auxiliary airbag chamber 7 will bulge outward along the upper and lower surfaces of the bed body to form a surrounding flange structure, which not only enhances the support stability, but also improves the comfort and anti-slip effect through the bulging shape.

[0044] Preferably, the side wall of the bed body 1 is also provided with an exhaust valve 13 and an inflation component 14.

[0045] By adopting the above technical solution, the exhaust valve 13 is used for rapid exhaust, and the inflation component 14 is an electric air pump, eliminating the need for manual inflation. Example 2

[0046] The present invention also provides a method for preparing the product disclosed in Example 1, the specific steps of which are as follows: A manufacturing process for a wire-drawing inflatable air mattress includes the following steps: S1 Wire Pulling Inspection: Flatten the PVC wire pull cloth and inspect the wire pull in the middle of the PVC wire pull cloth to ensure that there are no broken wires, no delamination, and no missing wires; S2 Top and bottom wall fabrication and bonding: Cut out the top and bottom walls of the bed body 1, and press the top and bottom walls of the bed body 1 onto the top and bottom walls of the tension layer 3 using high-frequency technology; The top and bottom walls of the bed body 1 are made of PVC composite polyester (polyester) fabric. S3 Internal capsule wall 8 welding: The capsule wall 8 is cut out and the upper and lower side walls of the capsule wall 8 are connected to the back of the top and bottom walls of the bed body 1 by high frequency technology. Among them, the capsule wall 8 is made of polyvinyl chloride; S4 Sidewall Welding: The sidewalls of the bed body 1 are cut out, and the sidewalls of the bed body are connected to the sidewalls of the top and bottom walls of the bed body 1 using high-frequency technology. The side wall of the bed body 1 is made of PVC composite polyester (polyester) fabric; S5 component assembly: Install an exhaust valve 13 and an inflation component 14 on the side wall of the bed body 1; S6 Finished Product Inspection: Conduct quality inspection on the installed bed body 1.

[0047] Working principle: When air is inflated into the bed body 1, the gas flows freely between the main air chamber 2 and the tension layer 3. The tension layer 3 is a three-dimensional structure made of PVC filament fabric. The PVC coated polyester fabric 5 on its upper and lower sides is tightly connected to the top and bottom walls of the bed body 1, respectively. The dense filaments 6 in the middle are straightened under air pressure, forming countless vertical "tendons". These taut wires 6 firmly hold the upper and lower walls of the bed body 1, dividing the originally soft surface of the main air chamber 2 into countless taut, pressure-resistant blocks 4. This forms a "prestressed" structure, making the entire bed surface resemble a drumhead that has been fully stretched. When a person lies on the bed, pressure is applied to a certain pressure-resistant block 4. At this time, since all the pressure-resistant blocks 4 are connected to each other through the tension layer 3, the pressure-resistant block 4 tries to sink inward. However, the pressure-resistant blocks 4 around it that are not under pressure will generate an outward and upward counter-pulling force through the tension layer 3, like the hands around it tightly holding the pressure-resistant block 4 and resisting its sinking. This "pulling the center out from the sides" mechanical mechanism distributes the localized downward pressure across the entire upper surface of the bed body 1, effectively counteracting the indentation caused by pressure and avoiding the "sinking" feeling of traditional air mattresses, providing rigid support close to that of a home mattress. The secondary air chambers 7 surrounding the bed body serve a stabilizing and edge-protecting function, preventing the user from slipping.

[0048] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
