Description

Technical Field

[0001] This utility model relates to the field of mattress technology, and in particular to an airbag and mattress. Background Technology

[0002] Currently, to meet the personalized needs of different users for sleep comfort, smart mattresses that can adjust their firmness to adapt to the curves of the human body have appeared on the market. These mattresses typically use multiple independent air chambers as support units. By using a matching air pump, air valve, and air tube to inflate or deflate the air chambers, the air pressure inside the air chambers is changed, thereby achieving adjustment of the firmness of the mattress as a whole or in specific areas.

[0003] However, the aforementioned prior art has at least the following technical problems:

[0004] In this type of mattress, air bladders are the primary load-bearing support. Due to the repeated inflation and deflation of air bladders and valves over long periods, materials are prone to aging, wear, or loosening, posing a risk of air leakage. If any air bladder leaks and the air pressure cannot be maintained, the support function in that area will completely fail, causing the mattress surface to collapse and rendering the product unusable for a short period. This severely impacts user experience and product reliability.

[0005] To control operating noise, smart mattresses are typically equipped with small air pumps with limited power and air flow. When a wide range of firmness adjustments is needed, the air pump takes a long time to complete the inflation or deflation process due to the large internal volume of the air chambers. This results in slow adjustment response, long waiting times for users, and a less than ideal "smart adjustment" experience.

[0006] Therefore, how to improve the adjustment response speed of a smart mattress without increasing the power and noise of the air pump, while simultaneously solving the technical problem of complete failure of the support function due to air leakage of the airbag, is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] The main purpose of this invention is to provide an airbag and mattress to solve the above-mentioned technical problems.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] An airbag includes: an airbag body having an inner cavity and an air nozzle disposed thereon; and a breathable elastomer disposed in the inner cavity of the airbag body; wherein a predetermined airflow channel is formed between the outer surface of the breathable elastomer and the inner wall of the airbag body, the airflow channel being connected to the air nozzle, and the inner end of the air nozzle extending into the airflow channel or into the breathable elastomer.

[0010] The airflow channel extends along at least one edge of the breathable elastomer between the outer surface of the breathable elastomer and the inner wall of the airbag body.

[0011] The breathable elastomer has a cuboid structure, and the airflow channel is provided along at least one vertical edge of the breathable elastomer.

[0012] The breathable elastomer has a notch at the vertical edge, and the notch and the inner wall of the airbag body together form the airflow channel.

[0013] The inner end of the air nozzle extends into the breathable elastic body and faces the central region of the breathable elastic body.

[0014] The breathable elastomer has multiple interconnected channels inside, which are respectively connected to the inner cavity of the airbag body and the air nozzle.

[0015] The breathable elastomer is a sponge and / or a latex.

[0016] The volume of the breathable elastomer occupies 80% to 98% of the internal volume of the airbag body.

[0017] The volume of the breathable elastomer occupies 90% to 95% of the internal volume of the airbag body.

[0018] The airbag has a first support state and a second support state; the bottom surface of the breathable elastomer is fixedly connected to the inner bottom wall of the airbag body, and when the airbag is in the first support state, the top surface of the breathable elastomer abuts against the inner top wall of the airbag body.

[0019] When the airbag is in the second support state, a preset gap is formed between the top surface of the breathable elastomer and the inner top wall of the airbag body.

[0020] A mattress includes a plurality of air bladders as described above, the plurality of air bladders being arranged in an array.

[0021] It also includes an air source control system, which is connected to the air nozzles of the multiple airbags and is used to control the inflation or deflation of the multiple airbags.

[0022] The beneficial technical effects of this invention are as follows: By incorporating a breathable elastomer within the inner cavity of the airbag body, this elastomer, acting as a filler, occupies most of the internal volume, thereby reducing the net volume of gas required for inflation or deflation when adjusting firmness. Simultaneously, the pre-designed airflow channel formed between the breathable elastomer and the inner wall of the airbag body provides a low-resistance, high-efficiency flow path for the gas, ensuring rapid and uniform gas distribution within the airbag. Combined, these two features significantly shorten the inflation / deflation time of the airbag without increasing the power and noise of the air pump, solving the problems of slow adjustment and long waiting times for users in existing smart mattresses. Furthermore, by inserting the inner end of the air nozzle into the airflow channel or the breathable elastomer, the risk of the air nozzle opening being accidentally blocked by the inner wall of the airbag body under pressure is avoided.

[0036] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0037] like Figures 1-6 As shown, this utility model provides an airbag that aims to solve the technical problems of low inflation and deflation efficiency, slow response, and complete loss of support function when leaking air in existing airbags. The airbag includes: an airbag body 10 with an inner cavity 11 and an air nozzle 20 disposed thereon; and a breathable elastomer 30 disposed within the inner cavity 11 of the airbag body 10. A pre-defined airflow channel 40 is formed between the outer surface of the breathable elastomer 30 and the inner wall of the airbag body 10. The airflow channel 40 is connected to the air nozzle 20, and the inner end of the air nozzle 20 extends into the airflow channel 40 or into the breathable elastomer 30.

[0038] In this embodiment, as Figures 1-3As shown, the airbag includes an airbag body 10 and a breathable elastomer 30 disposed inside the airbag body 10.

[0039] The airbag body 10 is the outer shell constituting the airbag and has an inner cavity 11 for containing gas. The airbag body 10 can be made of a material with good airtightness and flexibility, such as thermoplastic polyurethane (TPU). An air nozzle 20 is provided on the wall of the airbag body 10, which is used to connect to an external air source control system 80 to realize the inflation or deflation of the airbag.

[0040] The breathable elastomer 30 is disposed within the inner cavity 11 of the airbag body 10. This breathable elastomer 30 itself has a porous structure (interconnected internal channels), allowing gas to pass through, thus possessing "breathable" characteristics. Simultaneously, the breathable elastomer 30 has the "elastic" characteristic of deforming under external force and returning to its original shape after the force is removed. Its main function is to fill part of the internal space of the airbag body 10, thereby reducing the net gas volume required for inflation and deflation, and to provide a certain amount of physical support when the airbag body 10 leaks air or has insufficient air pressure.

[0041] The key feature of this embodiment is that a pre-defined airflow channel 40 is formed between the outer surface of the breathable elastomer 30 and the inner wall of the airbag body 10. This airflow channel 40 is the main path for the rapid flow of gas inside the airbag. Specifically, the airflow channel 40 can be formed by controlling the overall external dimensions of the breathable elastomer 30 to be slightly smaller than the internal cavity 11 of the airbag body 10, thereby naturally forming a surrounding or locally existing gap between the two, which constitutes the airflow channel 40 described in this embodiment.

[0042] The airflow channel 40 and the air nozzle 20 are interconnected, so that gas entering from the outside through the air nozzle 20 can enter the airflow channel 40 and quickly diffuse along the channel to its corresponding area, thereby achieving rapid inflation. Conversely, during deflation, the gas in the inner cavity 11 can also be quickly gathered to the air nozzle 20 and discharged through the airflow channel 40.

[0043] To further ensure a smooth inflation / deflation process, the inner end of the air nozzle 20 extends into the airflow channel 40 or into the breathable elastomer 30.

[0044] When the inner end of the nozzle 20 is inserted into the airflow channel 40, it can ensure that the incoming and outgoing airflow directly acts on this most efficient flow path, avoiding the risk of the nozzle 20 opening being accidentally blocked by the breathable elastomer 30 or the inner wall of the airbag body 10.

[0045] In another alternative implementation, the inner end of the air nozzle 20 can also extend into the interior of the breathable elastomer 30. Since the breathable elastomer 30 itself is breathable, gas can also enter the interior of the breathable elastomer 30 through the air nozzle 20, and then diffuse through the breathable elastomer 30 to the airflow channel 40 and the entire inner cavity 11, thus achieving effective gas exchange.

[0046] Through the above structural design, the airbag in this embodiment, by incorporating a breathable elastomer 30 internally, reduces the volume of gas required to achieve the same support effect. Simultaneously, by constructing an airflow channel 40 connecting to the air nozzle 20, it ensures that the remaining gas space can be inflated and deflated quickly and efficiently, thereby significantly improving the adjustment response speed. Furthermore, when the airbag body 10 is accidentally damaged and leaks air, the internal breathable elastomer 30 can still provide basic physical support, preventing the support area from completely collapsing, significantly improving product reliability and user safety.

[0047] In one embodiment, the airflow channel 40 extends along at least one edge of the breathable elastomer 30 between the outer surface of the breathable elastomer 30 and the inner wall of the airbag body 10.

[0048] In this embodiment, as Figures 3-5 As shown, when the breathable elastomer 30 is placed in the inner cavity 11 of the airbag body 10, the overall external dimensions of the breathable elastomer 30 are designed to be slightly smaller than the corresponding dimensions of the inner cavity of the airbag body 10. Thus, a gap of a certain width will naturally form in the outer peripheral region of the breathable elastomer 30, which constitutes the airflow channel 40 of this embodiment. The term "edge" here specifically refers to the ridge or corner region formed by the intersection of two or more surfaces of the breathable elastomer 30. For example, when the breathable elastomer 30 is a polyhedral structure (such as a cuboid, hexagonal prism, etc.), its edge is its edge.

[0049] The airflow channel 40 extends continuously along the edge contour of the breathable elastomer 30, forming one or more interconnected channel networks. For example, if both the airbag body 10 and the breathable elastomer 30 are rectangular in plan view, the airflow channel 40 can be formed between any one, several, or all four sides of the breathable elastomer 30 and the inner wall of the airbag body 10. When gas enters through the nozzle 20, it can quickly circulate or flow towards the distal end of the airbag along this peripheral airflow channel 40, thereby achieving rapid pressure equalization throughout the airbag cavity 11. Similarly, during deflation, gas from all parts of the cavity 11 can also quickly converge to the nozzle 20 and be discharged along this efficient edge channel.

[0050] This edge-extending airflow channel 40 design has the following advantages:

[0051] First, since the airflow channels 40 are distributed along the edge of the breathable elastomer 30, the internal space of the airbag body 10 can be utilized to the maximum extent, ensuring that the gas can quickly reach all areas of the airbag, thereby improving the uniformity and efficiency of inflation and deflation.

[0052] Then, the airflow channel 40 extending along the edge provides multiple flow paths for the gas. Even if a local area is temporarily narrowed due to the deformation of the breathable elastomer 30, the gas can still flow normally through other paths, ensuring the smooth flow of air.

[0053] During inflation, gas enters through the nozzle 20 and quickly enters the airflow channel 40 extending along the edge of the breathable elastomer 30, rapidly diffusing throughout the entire inner cavity 11. During deflation, the gas in the inner cavity 11 also gathers through the edge airflow channel 40 and is discharged through the nozzle 20.

[0054] This airflow channel 40 design, which extends along the edge, improves the efficiency of gas flow, thereby further shortening the inflation and deflation response time of the airbag.

[0055] In one embodiment, the breathable elastomer 30 has a cuboid structure, and the airflow channel 40 is arranged along at least one vertical edge of the breathable elastomer 30.

[0056] In this embodiment, as Figure 5 As shown, the breathable elastomer 30 adopts a cuboid geometry, which has six regular faces and twelve edges. The inner cavity 11 of the airbag body 10 is also designed accordingly as a cuboid shape to accommodate the cuboid structure of the breathable elastomer 30. "Vertical edges" refer to the edges of the cuboid structure of the breathable elastomer 30 that extend along the direction of gravity (i.e., the vertical direction) when the airbag is in normal working condition (e.g., placed horizontally in the mattress 100).

[0057] When the cuboid-shaped breathable elastomer 30 is placed in the inner cavity 11 of the airbag body 10, a predetermined gap exists between one or more of its vertical edges and the corresponding corners of the inner wall of the airbag body 10. This gap, extending vertically, constitutes the airflow channel 40 described in this embodiment. This design makes the airflow channel 40 the main flow channel connecting the top and bottom of the airbag.

[0058] For example, the nozzle 20 can be located on the side wall of the airbag body 10 and connected to one of the airflow channels 40 located on the vertical edge. When inflating, the gas enters through the nozzle 20 and can first rapidly diffuse upward and downward along the vertical airflow channel 40, and then laterally penetrate into the interior of the breathable elastomer 30 and fill the entire inner cavity 11, thereby achieving rapid and uniform inflation. The deflation process is similar; the gas can quickly converge along the channel on the vertical edge to the nozzle 20 for discharge.

[0059] In a preferred embodiment, airflow channels 40 can be provided along all four vertical edges of the breathable elastomer 30. This forms a symmetrical and efficient gas flow network, further improving the speed and uniformity of inflation and deflation, and ensuring that the airbag can rise and fall smoothly during adjustment.

[0060] By designing the breathable elastomer 30 as a cuboid structure and setting the airflow channel 40 on its vertical edge, this embodiment provides a simple, well-defined, and efficient gas inflation and deflation scheme, thereby improving the airbag's adjustment response performance.

[0061] In one embodiment, the breathable elastomer 30 has a notch 50 at the vertical edge, and the notch 50 and the inner wall of the airbag body 10 together form the airflow channel 40.

[0062] In this embodiment, as Figure 5 As shown, the notch 50 is a modification of the cuboid structure of the breathable elastomer 30, for example, by removing a portion of material from one or more selected vertical edges through cutting, molding, or other forming processes to create a groove or chamfer. The notch 50 can have various cross-sectional shapes, such as a right-angled triangle (i.e., a chamfer), a rectangle, a trapezoid, or an arc.

[0063] When the breathable elastomer 30 with the notch 50 is placed in the inner cavity 11 of the airbag body 10, the surface of the notch 50 and the inner wall of the airbag body 10 (especially the corner area of ​​the inner cavity 11) together form a channel with a defined cross-sectional shape and size, which is the airflow channel 40. In other words, the notch 50 on the breathable elastomer 30 provides part of the boundary of the channel, while the inner wall of the airbag body 10 constitutes the remaining boundary of the channel. Together, they form a complete and unobstructed airflow channel 40.

[0064] Compared to gaps formed solely by dimensional differences, constructing the airflow channel 40 by setting a pre-formed notch 50 has the following advantages:

[0065] First, the notch 50 makes the shape and size of the airflow channel 40 more controllable. By controlling the depth, width, and length of the notch 50, the cross-sectional area of ​​the airflow channel 40 can be accurately adjusted, thereby optimizing the gas flow performance.

[0066] Secondly, the presence of the notch 50 ensures that even when the breathable elastomer 30 is compressed and deformed, the airflow channel 40 can still maintain a certain degree of openness, avoiding the problem of the channel being completely blocked and affecting gas flow.

[0067] Furthermore, this structural design and manufacturing process is relatively simple, and it can be directly processed during the production of the breathable elastomer 30 without the need for additional complex assembly procedures.

[0068] When gas enters from the nozzle 20, it can quickly enter the airflow channel 40 formed by the notch 50 and the inner wall of the airbag body 10, and flow and distribute efficiently along the channel.

[0069] By using this notch 50 to cooperate with the inner wall, this embodiment ensures the structural stability of the airflow channel 40 while further improving the inflation and deflation response speed and reliability of the airbag.

[0070] In one embodiment, the inner end of the air nozzle 20 extends into the breathable elastomer 30 and faces the central region of the breathable elastomer 30.

[0071] In this embodiment, as Figure 3 As shown, after the air nozzle 20 passes through the wall of the airbag body 10, its inner port portion continues to extend and inserts into the solid portion of the breathable elastomer 30. To achieve this structure, an insertion hole matching the inner end of the air nozzle 20 can be pre-formed on the breathable elastomer 30.

[0072] The key to this embodiment is that the inner end of the air nozzle 20 not only extends into the breathable elastomer 30, but its opening direction also faces the central region of the breathable elastomer 30. Here, the "central region" should be understood as a three-dimensional spatial region located inside the breathable elastomer 30 and away from its various outer surfaces. Specifically, this central region can be defined as an internal virtual volume that maintains a predetermined distance from the top surface, bottom surface, and all sides of the breathable elastomer 30. In other words, the inner end of the air nozzle 20 is located inside the breathable elastomer 30, and there is a buffer distance made of the elastomer material between its position and any outer surface of the breathable elastomer 30.

[0073] This design has the following technical advantages:

[0074] First, by placing the opening of the air nozzle 20 in the central region of the breathable elastomer 30, the incoming and outgoing gas can diffuse more evenly in all directions or converge from all sides. Since the breathable elastomer 30 itself is breathable, the gas entering from the central region can act as a point source, permeating relatively evenly in all directions through the inherent porous structure or channels within the breathable elastomer 30. This achieves more uniform inflation and deflation of the entire airbag cavity 11, avoiding excessively high or low local pressure and improving the stability of the adjustment.

[0075] Secondly, the inner end of the air nozzle 20 is surrounded by a breathable elastomer 30. This structure can effectively prevent the opening of the air nozzle 20 from being accidentally blocked by the inner wall of the airbag body 10 when it is folded or compressed, ensuring that the air passage is always unobstructed and improving the reliability of the airbag operation.

[0076] By extending the inner end of the air nozzle 20 into the central area of ​​the breathable elastomer 30, this embodiment optimizes the distribution of airflow inside the airbag, which helps to achieve a smoother and more uniform inflation and deflation process, thereby improving the user's experience when adjusting the firmness.

[0077] In one embodiment, the breathable elastomer 30 has a plurality of interconnected channels inside, which are respectively connected to the inner cavity 11 of the airbag body 10 and the air nozzle 20.

[0078] In this embodiment, the multiple channels inside the breathable elastomer 30 are a concrete manifestation of its breathable properties (the channels are not individually labeled in the accompanying drawings). These channels can be naturally formed pore structures during the manufacturing process of the breathable elastomer 30, such as interconnected air pores formed during the foaming process of a sponge, or artificially pre-designed regular channels.

[0079] The connectivity of the channels is reflected in two aspects: on the one hand, these channels are connected to the air nozzle 20, so that the gas input from the air nozzle 20 can enter the internal channel network of the breathable elastomer 30; on the other hand, these channels are also connected to the inner cavity 11 of the airbag body 10, especially to the airflow channel 40 between the outer surface of the breathable elastomer 30 and the inner wall of the airbag body 10.

[0080] During inflation, the gas enters through the nozzle 20, first enters the channel directly connected to the nozzle 20, and then diffuses in all directions through the interconnected channel network inside the breathable elastomer 30. Finally, it enters the airflow channel 40 and other internal cavities 11 of the airbag body 10 through the channel outlet.

[0081] During the deflation process, the gas flows in the opposite direction. The gas distributed in various parts of the airbag body 10 enters the interior of the breathable elastomer 30 through the channel, and is discharged through the channel connected to the air nozzle 20 after being collected.

[0082] This multi-channel structural design improves the flow efficiency of gas inside the breathable elastomer 30, provides multiple parallel gas flow paths for rapid inflation and deflation, and also enhances the breathability of the breathable elastomer 30.

[0083] In one embodiment, the breathable elastomer 30 is a sponge and / or a latex.

[0084] In this embodiment, the sponge is a typical porous elastic material, made from polymers such as polyurethane through a foaming process. The sponge has a large number of interconnected pores, which give it excellent air permeability. Simultaneously, the sponge exhibits excellent elastic recovery properties, rapidly returning to its original shape after compression, providing stable physical support for the airbag.

[0085] Latex refers to porous elastic materials formed by foaming natural or synthetic latex. Latex also possesses a rich pore structure and good air permeability, and exhibits superior elasticity and durability. The elastic modulus and damping properties of latex enable it to provide a comfortable supportive feel.

[0086] In practical applications, either sponge or latex can be used alone as the breathable elastomer 30, or a combination of both can be used. For example, a composite structure of sponge and latex can be adopted to fully utilize the advantages of both materials.

[0087] In one embodiment, the volume of the breathable elastomer 30 occupies 80% to 98% of the internal volume of the airbag body 10.

[0088] In this embodiment, as Figure 3 As shown, the internal volume of the airbag body 10 refers to the total volume of its inner cavity 11 when the airbag body 10 is in its designed working shape (e.g., when filled with gas to standard pressure). The volume of the breathable elastomer 30 refers to the actual space volume occupied by the elastomer itself (excluding its internal pores).

[0089] When the volume ratio of the breathable elastomer 30 reaches 80%, the amount of gas that needs to be inflated into the air bladder can be reduced. According to the gas law, under the same pressure requirements, the reduction in available gas space directly reduces the amount of gas required for inflation, thereby significantly shortening the inflation time. At the same time, the 80% filling ratio ensures that the breathable elastomer 30 can provide sufficient physical support when the air bladder leaks, preventing significant sagging of the mattress surface 100.

[0090] Setting the upper limit to 98% ensures that a certain amount of gas space is still retained within the airbag, which is necessary for adjusting the firmness. If the volume ratio of the breathable elastomer 30 is too high (e.g., exceeding 98%), the remaining gas space will be too small, which may reduce the sensitivity of inflation / deflation adjustment and prevent the achievement of the desired firmness variation effect.

[0091] In one embodiment, the volume of the breathable elastomer 30 occupies 90% to 95% of the internal volume of the airbag body 10.

[0092] In this embodiment, when the volume ratio is between 90% and 95%, the inflation and deflation efficiency of the airbags can reach a relatively ideal level, while the support effect of the breathable elastomer 30 and the smoothness of air circulation also reach the optimal balance. For example, in a specific application, using high-resilience sponge with a volume ratio of 95% as the breathable elastomer 30 can ensure rapid response while maintaining a flat surface on the mattress 100 after the airbags are completely deflated, without significant sagging, resulting in an excellent user experience.

[0093] In one embodiment, the airbag has a first support state and a second support state; the bottom surface of the breathable elastomer 30 is fixedly connected to the inner bottom wall of the airbag body 10, and when the airbag is in the first support state, the top surface of the breathable elastomer 30 abuts against the inner top wall of the airbag body 10.

[0094] In this embodiment, the first support state can be understood as the airbag being in a low-pressure or no-pressure state. This occurs after the airbag has been completely deflated, or when the airbag leaks unexpectedly, causing a significant drop in pressure. When the airbag is in the first support state, the top surface of the breathable elastomer 30 abuts against the top wall inside the airbag body 10.

[0095] Specifically, such as Figure 1 As shown, in the first supported state, due to the lack of sufficient internal air pressure to support the airbag body 10, the airbag body 10 tends to contract or be flattened under external force (such as human body pressure). At this time, the internal breathable elastomer 30, due to its inherent size and elasticity, plays a major supporting role. The top surface of the breathable elastomer 30 presses upward against the inner top wall of the airbag body 10, while its bottom surface presses downward against the inner bottom wall of the airbag body 10, thereby supporting the overall height of the airbag and preventing it from collapsing completely. This contact state ensures that even without air pressure, the airbag can still provide effective physical support, guaranteeing the basic usability and safety of the product.

[0096] In one embodiment, when the airbag is in the second support state, a preset gap is formed between the top surface of the breathable elastomer 30 and the inner top wall of the airbag body 10.

[0097] In this embodiment, the second support state can be understood as the airbag being in a high-pressure or normal operating pressure state. This occurs when the airbag is inflated with sufficient gas to achieve a preset stiffness. When the airbag is in the second support state, a preset gap is formed between the top surface of the breathable elastomer 30 and the top wall inside the airbag body 10.

[0098] Specifically, when the airbag is inflated, as the air pressure increases, the gas pressure acts on the inner wall of the airbag body 10, causing it to expand outward. Under this action, the top surface of the breathable elastomer 30, which was originally in contact with the inner top wall of the airbag body 10 in the first supported state, will separate from the inner top wall of the inflated airbag body 10, thereby forming a preset gap between the two.

[0099] The formation of this pre-set gap is a direct manifestation of the airbag transitioning from physical support (first support state) to gas support (second support state). The existence of the gap indicates that the airbag's support force is mainly provided by internal air pressure at this point, and the airbag's firmness can be controlled by adjusting the air pressure. Simultaneously, this gap also becomes part of the gas flow within the inner cavity 11, facilitating rapid pressure equalization.

[0100] In summary, by defining the relative positional relationship of the internal components in the first and second support states, this embodiment clearly reveals how the airbag achieves seamless switching between support modes under different operating conditions (no air pressure / low air pressure vs. high air pressure): In the first support state, basic physical support is provided by the contact between the breathable elastomer 30 and the inner top wall of the airbag body 10; in the second support state, by forming a preset gap, adjustable support is provided by air pressure. This design ensures that the airbag can function under any circumstances, greatly improving the reliability and adaptability of the product.

[0101] like Figure 6 As shown, corresponding to the above-described airbag, this embodiment of the present invention also provides a mattress 100, which is designed to provide adjustable, responsive, and highly reliable sleep support. The mattress 100 includes a plurality of airbags as described in the preceding embodiments, the plurality of airbags being arranged in an array.

[0102] In this embodiment, the support layer of the mattress 100 consists of multiple independent airbags. These airbags can be arranged in a matrix, for example, in multiple rows and columns, to cover the entire effective support area of ​​the mattress 100. The number and layout of the airbags in the array can be flexibly designed according to the size of the mattress 100 (e.g., single or double) and functional requirements (e.g., whether zoned support is required). For example, in a double mattress 100, it can be set up with left and right sections, each containing an array of multiple airbags to achieve independent adjustment for different users.

[0103] Each airbag possesses the structural features described in the aforementioned embodiments, namely, it has an internal breathable elastomer 30 and an airflow channel 40, among other structures. Therefore, the support system of the entire mattress 100 inherits the advantages of a single airbag: rapid inflation and deflation response, and even in the event of leakage in any one or more airbags, the internal breathable elastomer 30 can still provide effective support, preventing localized deep collapse of the mattress 100 surface, thus ensuring the overall reliability of the mattress 100.

[0104] In one embodiment, the mattress 100 further includes an air source control system 80, which is connected to the air nozzles 20 of the plurality of air bladders and is used to control the inflation or deflation of the plurality of air bladders.

[0105] In this embodiment, as Figure 7 As shown, the gas source control system 80 is an integrated control unit, including:

[0106] Air source 81: For example, a small, low-noise air pump, used to provide compressed air to the airbags. Valve assembly 82: Composed of multiple solenoid valves and other valve components, each valve corresponding to control the inflation, pressure holding, and deflation of one or a group of airbags. Air line 83: Used to connect the air pump, valve assembly 82, and the air nozzles 20 of each airbag. Controller 84: A microprocessor (MCU) with a built-in control program, used to receive user commands and control the start / stop of the air pump and the opening / closing of the valve assembly 82 according to preset logic, thereby regulating the air pressure in each airbag. Control panel 85: Can be a remote control, mobile APP, etc., through which the user issues adjustment commands.

[0107] The air source control system 80 is connected to the air nozzles 20 of each airbag individually or in groups via air pipelines 83. When the system receives an adjustment command, the controller 84 drives the corresponding valve to open and starts the air pump to inflate the designated airbag, or opens the exhaust valve to deflate the designated airbag. Due to the rapid response characteristic of each airbag, the adjustment command of the air source control system 80 can be executed quickly, thereby realizing the rapid adjustment of the firmness of the mattress 100 as a whole or in different areas such as the shoulders, waist, and legs.

[0108] In summary, the mattress 100 of this embodiment solves the problems of slow adjustment and poor reliability of existing smart mattresses 100 by arranging multiple airbags with built-in breathable elastomers 30 in an array and integrating an air source control system 80, thus providing users with a mattress 100 that offers a better experience and is safer and more durable.
