Description

Technical Field

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

[0002] A bed is a common piece of furniture in daily life. A bed typically consists of a bed frame and a mattress. When in use, the mattress sits between the user and the bed frame, enhancing comfort. Mattresses are usually soft and resilient. Common mattresses include spring mattresses, foam mattresses, and latex mattresses. Different materials result in varying degrees of elasticity and support for the body, leading to different levels of comfort and sleep quality.

[0003] The elasticity of a mattress is generally fixed (not considering changes in elasticity due to aging). Mattresses with fixed elasticity have certain limitations. For example, different users have different needs regarding mattress elasticity; some prefer a softer feel, while others prefer a firmer feel. Mattresses with fixed elasticity cannot cater to the diverse needs of users. To address this issue, some mattresses incorporate multiple independent air chambers. The elasticity of the mattress is adjusted by inflating and deflating these air chambers, thus meeting the needs of different users. However, because these air chambers are independent and numerous, the number of connecting interfaces and solenoid valves is also large, resulting in a very complex structure.

[0004] In addition, when sleeping, people usually want a soft and supportive mattress to improve sleep quality. However, when turning over or getting up, a soft mattress can provide less support, making it difficult to turn over or get up, especially for women with less muscle mass and the elderly.

[0005] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects.

[0006] The above content is only used to help understand the technical solution of this application and does not constitute an admission that the above is prior art. Utility Model Content

[0020] Furthermore, the airbag support module includes a plurality of airbags spaced apart along a first direction, and a plurality of the support portions of each airbag are arranged along a second direction perpendicular to the first direction, wherein one of the first direction and the second direction is the length direction of the mattress and the other is the width direction of the mattress.

[0021] Furthermore, the airbag includes a plurality of support portion groups spaced apart along a first direction, each support portion group including a plurality of support portions spaced apart along a second direction, the first direction being perpendicular to the second direction, one of the first direction and the second direction being the length direction of the mattress, and the other being the width direction of the mattress.

[0022] Furthermore, the airbag support module includes only one airbag.

[0024] Furthermore, the airbag comprises an inelastic fabric that covers the entire cavity of the airbag;

[0025] The cross-section of the inflated airbag is circular;

[0026] During use, the internal air pressure of the airbag is not lower than one standard atmosphere.

[0027] Furthermore, the elastic support is made of a soft material and has multiple mounting holes communicating with its bottom surface. Each support part is disposed in one of the mounting holes, which are blind holes or through holes.

[0028] The first connecting tube is located outside the elastic support; or, the first connecting tube is embedded in the elastic support.

[0029] Furthermore, the elastic support body includes a plurality of arrayed helical springs, and each of the support portions is disposed within the inner hole of one of the helical springs.

[0030] Furthermore, the mattress also includes a soft layer at the bottom of the elastic support and a soft padding layer above the elastic support.

Moreover, the continuous airbags can reduce the number of airbags used, reduce the number of supporting parts, and simplify installation. On the other hand, by inflating and deflating the airbags, the support performance of the mattress can be adjusted to suit more users. After the mattress is inflated and hardened, it also facilitates the user's turning over and getting up. Attached Figure Description

[0066] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0067] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0068] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0069] Some embodiments of this utility model propose a mattress, such as Figure 1 and Figure 2 As shown, the mattress includes an elastic support body 1, an airbag support module 2, and an inflation / deflation system.

[0070] The elastic support element 1 is the main support carrier of the mattress. It can be made of soft materials such as foam or latex, or it can include a spring array. The material of the elastic support element 1 determines the type of mattress. For example, when the elastic support element 1 is foam, the mattress is a foam mattress; when the elastic support element 1 is latex, the mattress is a latex mattress; and when the elastic support element 1 includes a spring array, the mattress is a spring mattress.

[0071] Airbag support module 2 provides additional support, allowing the mattress's elasticity and support to be adjusted. For example... Figures 2 to 4 As shown, the airbag support module 2 includes at least one continuous airbag 20. A continuous airbag 20 means that the airbag 20 is a single piece, rather than multiple airbags 20 connected by components such as air tubes. This reduces the number of airbags used, decreases the number of supporting parts, and simplifies installation. The airbag 20 includes multiple spaced-apart support portions 200 and a first connecting tube portion 201 connecting two adjacent support portions 200. The support portions 200 are at least partially disposed within the elastic support body 1. In this specification, unless otherwise specified, "multiple" refers to two or more.

[0072] The inflation / deflation system is used to inflate and deflate the airbag 20.

[0073] When the inflation / deflation system supplies air to the air chambers 20, the air chambers 20 become firmer, and the overall elasticity of the mattress decreases, resulting in higher support performance in the thickness direction (the mattress becomes firmer). When some of the air is released from the air chambers 20 through the inflation / deflation system, the air chambers 20 gradually shrink and soften, the overall elasticity of the mattress increases, and the support performance in the thickness direction decreases (the mattress becomes softer). Thus, by inflating and deflating the air chambers through the inflation / deflation system, the firmness of the air chambers 20 can be adjusted, thereby adjusting the support performance of the mattress. Adjusting the firmness of the mattress can provide a more comfortable user experience. For example, when sleeping, the mattress can be softened to improve sleep comfort, and when turning over or getting up, the mattress can be firmed to facilitate turning over or getting up. It is understandable that by using the air chambers 20 and the elastic support body 1 to provide support, the number and volume of the air chambers 20 required can be reduced, allowing the air chambers 20 to change the mattress's support performance more quickly during inflation and deflation, achieving better support performance with smaller air chambers 20.

[0074] Optionally, the support portion 200 includes at least one bent portion located within the elastic support 1.

[0075] In some embodiments, the support portion 200 includes a first tube portion 2000 and a second tube portion 2001 arranged in parallel, and a second connecting tube portion 2002 connecting the first tube portion 2000 and the second tube portion 2001. In two adjacent support portions 200, the second tube portion 2001 of the preceding support portion 200 and the first tube portion 2000 of the following support portion 200 are connected by the first connecting tube portion 200. It is understood that in the airflow path, the support portion 200 that the airflow passes through first is further forward, and the support portion 200 that the airflow passes through first is the foremost support portion 200. The second connecting tube portion 2002 is completely located within the elastic support body 1, and the first tube portion 2000 and the second tube portion 2001 are partially or completely located within the elastic support body 1 to adjust the support performance of the elastic support body 1.

[0076] Optionally, the first tube section 2000 and the second tube section 2001 are straight tubes, such as... Figure 2 As shown, the axial direction of the first tube 2000 and the second tube 2001 is aligned with the thickness direction of the mattress (i.e., α1 is 0°). When the support part 200 is inflated, its axial support performance can be significantly enhanced, giving the mattress a greater upper limit to its support performance. This means the mattress firmness can be adjusted more widely, resulting in better adaptability. Furthermore, it can more efficiently improve the mattress's support performance in the thickness direction, allowing the mattress to harden or soften faster, while maintaining better support in the thickness direction. Additionally, a thicker support layer can be constructed using airbags 20 with a relatively smaller diameter, achieving excellent support. Furthermore, the smaller overall volume of the airbags 20 allows for better support performance with a smaller air supply, further improving the speed and responsiveness of mattress firmness adjustments. Optionally, the outer diameter of the airbags 20 is between one and three inches. It is understood that the size of the airbags 20 will vary depending on the internal air pressure; the size of the airbags 20 can be based on the external dimensions when the internal air pressure is one standard atmosphere.

[0077] Understandably, in the above solution, the airbag 20 primarily expands and deforms horizontally when it hardens. Compared to solutions that mainly provide support through expansion and deformation in the thickness direction, this reduces the amount of deformation in the mattress thickness direction during airbag 20 inflation, decreasing the feeling of being pushed up and thus minimizing disturbance to the user, which is beneficial for ensuring the user's sleep quality. For example, the user's turning over can be detected after falling asleep. When a turning over occurs, airbag 20 is inflated to enhance support and assist in turning over, and the feeling of being pushed up when airbag 20 inflates is even smaller, making it less likely to disturb the sleeper.

[0078] The first connecting tube 201 and the second connecting tube 2002 can be strip-shaped (straight tube) or curved tube. Their shapes are determined by the distance between the two first tubes 2000 and the second tube 2001 they are connected to. For example, when the distance between the first tubes 2000 and the second tube 2001 is small, a curved tube shape can be used, and when the distance is large, a strip-shaped tube shape can be used. Figure 2 In the illustrated embodiment, the first connecting pipe portion 201 is in the shape of a straight pipe, and the second connecting pipe portion 2002 is in the shape of a bent pipe.

[0079] In some embodiments, the airbag 20 is formed by bending a strip-shaped flexible tube. When the airbag 20 is not installed into the elastic support 1, it is strip-shaped, similar to the shape of a water hose. When uninflated, it is flat for easy storage and transportation. Bending allows the airbag 20 to be easily inserted into the elastic support 1, forming the support portion 200 and the first connecting pipe portion 201, etc. Thus, the airbag 20 forms a single continuous pipe, with a simple structure and manufacturing process, enabling large-scale fully automated production and lower production costs. Optionally, installation can be performed with the airbag 20 uninflated for ease of installation.

[0080] In some embodiments, such as Figure 5 and Figure 6 As shown, the airbag support module 2 also includes an elastic support rod 202 connected to the airbag 20. When the airbag 20 is not bent, the elastic support rod 202 extends along the length of the airbag 20. After the airbag 20 is bent, the elastic support rod 202 undergoes elastic deformation, creating a cavity at the corner of the airbag 20, preventing dead angles or blockages due to small corners, thus ensuring airflow. This facilitates reliable airflow to all parts of the airbag 20 during inflation and deflation, resulting in more consistent support performance between the mattress and the corresponding parts of the airbag support module 2.

[0081] In some embodiments, the elastic strut 202 is located inside the airbag 20, for example, as Figure 5 As shown, the elastic strut 202 is connected to the inner surface of the airbag 20. In other embodiments, such as... Figure 6 As shown, the elastic strut 202 is located outside the airbag 20 and is connected to the outer surface of the airbag 20. In some other embodiments, the elastic strut 202 is located within the material layers of the airbag 20, which is formed of multiple layers of material, with the elastic strut 202 located between two material layers.

[0082] Optionally, the flexible support rod 202 is made of metal wire.

[0083] The firmness of the part of the mattress corresponding to the airbag support module 2 is adjustable. The airbag support module 2 includes multiple arrayed support units 200, which make the firmness of a certain area of ​​the mattress adjustable.

[0084] In some embodiments, such as Figure 7 and Figure 8 As shown, the airbag support module 2 includes multiple airbags 20 spaced apart along a first direction. Multiple support portions 200 of each airbag 20 are arranged along a second direction perpendicular to the first direction. In this way, the support portions 200 of the multiple airbags 20 form an array distribution, providing dispersed point support to a certain area of ​​the mattress, thus making the required volume of the airbags 20 smaller. Figure 7 In the illustrated embodiment, the airbag support module 2 includes eight airbags 20. Figure 8 It shows Figure 7 A schematic diagram of one airbag 20. When the airbag support module 2 has multiple airbags 20, the volume of each airbag 20 is relatively smaller, which facilitates faster adjustment of the mattress firmness. Moreover, the firmness of each airbag 20 can be different, thus allowing the firmness of different parts of the mattress to be adjusted as needed.

[0085] In other embodiments, such as Figure 9 and Figure 10 As shown, the airbag 20 includes multiple support portion groups arranged along a first direction, and each support portion group includes multiple support portions 200 arranged at intervals along a second direction. In this way, each airbag 20 can form a larger area of ​​support, which can reduce the number of airbags 20 used and reduce the number of interfaces and their associated components. Figure 9 In the illustrated embodiment, the airbag support module 2 includes four airbags 20, each airbag 20 including two support portions arranged along a first direction. Optionally, as... Figure 10 As shown, the airbag support module 2 includes only one airbag 20. This makes the pressure inside the airbag 20 more consistent, providing a more uniform support force. At the same time, it reduces the number of interfaces and their associated parts, and makes it easier to control the pressure of the airbag 20.

[0086] Optionally, one of the first direction and the second direction is the length direction of the mattress, and the other is the width direction. In the embodiment shown in the accompanying drawings of this specification, the first direction is the length direction of the mattress, and the second direction is the width direction of the mattress.

[0087] Understandably, a smaller number of airbags 20 can provide a larger number of support sections 200. For example, a single airbag 20 can form dozens or even hundreds of support sections 200. These support sections 200 constitute support points for the human body. The arrayed support sections 200, embedded in the elastic support body 1, not only provide rapidly adjustable support but also significantly reduce the total volume and volume change rate of the required airbags 20. A small amount of air entering or leaving the airbags can quickly alter their air pressure and elasticity. Furthermore, the upper ends of each support section 200 are not connected. The person lying on it applies vertical pressure to the support unit 200, while horizontal traction is almost negligible. This significantly improves the mattress's coverage, resulting in more consistent pressure across the body, thus preserving the excellent sleeping feel of traditional foam and spring mattresses.

[0088] The support portion 200 is constrained by the elastic support body 1. Optionally, after the airbag 20 is inflated (e.g., with an internal pressure of standard atmosphere), the support portion 200 located within the elastic support body 1 is radially constrained by the elastic support body 1, where radial refers to the direction perpendicular to the thickness direction of the mattress. After inflation, the first tube 2000 and the second tube 2001 abut against the elastic support body 1 in the radial direction, thereby being constrained by the elastic support body 1. The folded tubular airbag structure is dispersed and constrained by the elastic support body 1, which can significantly reduce the required volume of the airbag 20. At the same time, the soft surface of the airbag 20 is difficult to change volume under pressure due to the constraint, resulting in a higher elasticity change under the premise of adding or subtracting the same amount of gas, thereby quickly adjusting the support performance of the mattress. Optionally, after the airbag 20 is inflated, the first tube 2000 and the second tube 2001 come into contact to further enhance the constraint on the first tube 2000 and the second tube 2001.

[0089] In some embodiments, the elastic support 1 is made of a soft material, such as sponge, and has a plurality of mounting holes 11 communicating with its bottom surface 10. Each support portion 200 is disposed in one mounting hole 11. The mounting holes 11 can limit the position of the support portion 200 so that the support portion 200 can be in a relatively fixed position when inflated and deflated. Figure 1 In the illustrated embodiment, the mounting hole 11 is circular. It is understood that in other embodiments, the mounting hole 11 may be other shapes, such as rectangular, elliptical, elongated, or conforming to the shape of the inflated support portion 200, in order to better limit the support portion 200.

[0090] In some embodiments, such as Figure 2 As shown, the mounting hole 11 is a blind hole, and the top of the elastic support 1 has a spacer portion 13 located above the support portion 200, which can increase comfort. In other embodiments, such as Figure 11As shown, the mounting hole 11 is a through hole. Optionally, the mattress also includes a soft padding layer 50 located on top of the elastic support 1, which covers the mounting hole 11 to increase comfort. Optionally, the soft padding layer 50 is made of the same material as the elastic support 1.

[0091] In some embodiments, such as Figures 12 to 14 As shown, the elastic support body 1 includes a plurality of arrayed helical springs 12, with each support portion 200 disposed within the inner hole of a helical spring 12, the position of the support portion 200 being limited by the inner hole of the helical spring 12. The mattress also includes a soft padding layer 50 located on top of the elastic support body 1 to improve comfort. Optionally, when the airbag 20 is inflated, the support portion 200 compresses the helical spring 12, achieving binding with the helical spring 12 by tension alone. It should be noted that it is not necessary to have a support portion 200 within every helical spring 12; for example, a support portion 200 can be provided every other helical spring 12.

[0092] It is understood that the embodiment of the elastic support 1 including multiple arrayed helical springs 12 can be achieved by inserting airbags 20 into an existing spring mattress, with minimal changes to the original spring mattress processing.

[0093] In some embodiments, the mattress further includes a soft layer 51 located at the bottom of the elastic support 1. The soft layer 51 supports the bottom of the elastic support 1 and the airbag 20, thus better confining the airbag 20. For example, Figure 14 A schematic diagram is shown of a mattress that includes multiple arrayed helical springs 12 and a soft layer 51. The mattress also includes an annular layer 32 surrounding the elastic support 1. This annular layer 32 is also made of a soft material, such as foam or latex, and serves to restrain the elastic support 1 and improve lateral protection. For example, Figure 15 A schematic diagram is shown of a mattress that includes both an elastic support 1 made of soft material and a soft layer 51.

[0094] Optionally, the diameter of the support portion 200 is greater than or equal to half the diameter of the mounting hole 11 and the inner diameter of the coil spring 12, so that after the airbag 20 is inflated (e.g., when the internal air pressure is one standard atmosphere), the support portion 200 can be radially constrained by the elastic support body 1 (e.g., the mounting hole 11 or the wall of the inner hole), and the first tube portion 2000 and the second tube portion 2001 are also tightly attached together, which can better improve the support performance. Further optionally, the first tube portion 2000 and the second tube portion 2001 are directly glued together. In some embodiments, the first connecting tube portion 201 is embedded in the elastic support body 1, for example, referring to... Figure 16A groove 14 for accommodating the first connecting tube 201 can be formed on the bottom surface 10 of the elastic support 1 to accommodate the first connecting tube 201. This limits the position of the first connecting tube 201 and reduces the lifting sensation caused by the airbag 20 after inflation. In other embodiments, the first connecting tube 201 is located outside the elastic support 1 (below the bottom surface 10) and between the soft layer 51 and the elastic support 1. Optionally, such as... Figure 15 As shown, the top surface 310 of the soft layer 51 is provided with a groove 15 for placing the first connecting tube 201, so as to limit the first connecting tube 201 and reduce the lifting sensation generated after the airbag 20 is inflated.

[0095] In some embodiments, the mattress further includes a cover layer 5, which covers at least the elastic support 1 and the airbag support module 2. When the mattress includes a soft padding layer 50 and / or a soft layer 51, the cover layer 50 covers both the soft padding layer 50 and / or the soft layer 51. Figure 17 It shows Figure 14 The diagram shown illustrates the structure with the covering layer 5. Figure 18 It shows Figure 15 The diagram shown illustrates the structure with the covering layer 5. Figure 19 It shows Figure 16 The diagram shown illustrates the structure with a covering layer 5.

[0096] In some embodiments, the first connecting tube portion 201 is at least partially abutted on both sides along its thickness direction such that the first connecting tube portion 201 forms at least two channels 2010. For example... Figure 20 As shown, the first connecting tube portion 201 has a first portion 2011 and a second portion 2012 located above and below a horizontal plane 2013 passing through its center, respectively. The first portion 2011 is located on the upper side in the thickness direction of the first connecting tube portion 201, and the second portion 2012 is located on the lower side in the thickness direction of the first connecting tube portion 201. The first portion 2011 and the second portion 2012 are at least partially connected to form at least two channels 2010. Figure 21 It shows Figure 20 This is a schematic diagram showing the first portion 2011 and the second portion 2012 of the first connecting tube 201 partially connected. Optionally, the middle portions of the first portion 2011 and the second portion 2012 are connected to form two channels 2010 of the same size. Figure 20 and Figure 21As shown, the first connecting tube portion 201 has a top end 201a and a bottom end 201b in the thickness direction of the mattress. The top end 201a and the bottom end 201b are connected to form two channels 2010. Optionally, the connecting portion 201c of the first portion 2011 and the second portion 2012 extends along the axial direction of the connecting tube portion to improve the connection force. The first portion 2011 and the second portion 2012 can be connected by means of adhesive bonding, welding, or heat fusion.

[0097] By connecting the first part 2011 and the second part 2012, the thickness of the first connecting tube 201 after the airbag 20 is inflated can be significantly reduced. This minimizes the increase in size of the first connecting tube 201 after inflation, preventing excessive lifting of the elastic support body 1 even without grooves 14 and 15, thus reducing disturbance to the sleeping person. When grooves 14 and 15 are provided, their depth can be reduced, improving the uniformity of firmness across the mattress. Furthermore, the reduced thickness of the first connecting tube 201 after inflation after connecting the first part 2011 and the second part 2012 reduces the overall capacity of the airbag 20, allowing for faster inflation and deflation of the airbag 20 and increasing the speed of mattress firmness changes. It is understood that the connection between the first part 2011 and the second part 2012 is not limited to a single location; there could be two or more locations to further reduce the thickness of the first connecting tube 201 after inflation.

[0098] It is understood that in some embodiments, the second connecting pipe portion 2002 may also adopt the structure of the first connecting pipe portion 201 described above, for example... Figure 21 The structure shown.

[0099] In some embodiments, when the internal air pressure of the airbag 20 is between one and 1.5 atmospheres, the volume change rate of the airbag 20 does not exceed 15%. The volume change rate of the airbag 20 can be adjusted by its material. Optionally, the airbag 20 comprises a non-elastic fabric that covers the entire cavity of the airbag 20. The fabric is soft and expands and deforms when the airbag 20 is inflated, but after the airbag 20 is inflated to one atmosphere, the volume of the airbag 20 remains essentially unchanged because the fabric does not undergo elastic deformation. Meanwhile, the support portion 200 is constrained by the elastic support body 1, thus better reducing the deformation of the mattress during the inflation and deflation of the airbag 20, resulting in greater comfort. The non-elastic soft fabric can be, for example, cotton, linen, polyester, or nylon. Optionally, the airbag 20 is made of a single-layer material with good airtightness. For example, a fusible organic material such as TPU, PP, PC, or polyester can be coated onto the fabric to give it good airtightness. The airbag 20 can also be made of two or more layers of material, with a soft, non-elastic fabric covering the outermost layer of the airbag 20, and the inner layer made of a highly airtight material.

[0100] Optionally, when the internal air pressure of the airbag 20 is between one standard atmosphere and the maximum working air pressure of the airbag 20, the volume change rate of the airbag 20 shall not exceed 15%. Further optionally, the maximum working air pressure of the airbag 20 is 1.5 standard atmospheres.

[0101] Understandably, since the volume (and size) of the airbag 20 changes little after inflating to one standard atmosphere, and its volume may even remain unchanged when the fabric is inelastic, the efficiency of changing its internal air pressure through inflation and deflation is higher, making it easier to quickly change the support performance of the airbag 20. Optionally, the cross-section of the inflated airbag 20 is circular, which reduces the possibility of changing its volume through deformation, further improving the efficiency of air pressure change. For example, an airbag with a square cross-section can change its volume through surface bending even if its surface is inelastic.

[0102] Optionally, during use, the internal air pressure of the airbag 20 is not lower than one standard atmosphere. That is, during use, the inflation and deflation of the airbag 20 is always carried out at a pressure greater than one standard atmosphere. In this way, the size of the airbag 20 changes less or even no longer during use. Inflation and deflation only bring about changes in support or elasticity, resulting in better comfort and less likelihood of disturbing the sleeper due to size changes.

[0103] In some embodiments, the airbag 20 has an opening at only one end, and the inflation / deflation system includes an air pump connected to the opening end, which inflates or deflates the airbag 20.

[0104] In other embodiments, the airbag 20 includes an inlet end 22 for gas entry and an outlet end 21 for gas exit. The inflation / deflation system includes an air supply device 3 and an air exhaust device 4. The air supply device 3 is connected to the inlet end 22 for supplying air to the airbag 20. The air exhaust device 4 is connected to the outlet end 21 for deflating the airbag 20.

[0105] In some embodiments, such as Figure 1 and Figure 22 As shown, the air supply device 3 includes an air tank 30 and an air pump 31 connected to the air tank 30. The air tank 30 includes an air inlet valve 300 connected to the air inlet end 22. The air pump 31 stores air in the air tank 30 and supplies air to the airbag 20 through the air tank 30. This allows the air pump 31 to replenish the air tank 30 when the person is not asleep (e.g., during the day), and the air tank 30 is used to inflate the airbag 20 when it needs inflation. Since the sound of the air tank 30 supplying air to the airbag 20 is quieter than the sound of the air pump 31 operating, inflating the airbag 20 through the air tank 30 while the person is asleep (e.g., at night) can reduce the impact on sleep. Optionally, the air pump 31 replenishes the air tank 30 during the day, and the air tank 30 supplies air to the airbag 20 at night to reduce the impact on nighttime rest.

[0106] In some embodiments, the venting device 4 includes a vent valve through which gas is discharged from the airbag 20. In other embodiments, the venting device 4 may also include an air pump to accelerate the outflow of gas from the airbag 20 by suction, thereby enabling it to soften more quickly.

[0107] In some embodiments, the covering layer 5 simultaneously covers the inflation / deflation system (air supply device 3 and air exhaust device 4) so ​​that the mattress can be transported and used as a whole. Optionally, both the air supply device 3 and the air exhaust device 4 are embedded within the elastic support body 1, making the whole unit easier to transport and use, and the elastic support body 1 can absorb noise, resulting in quieter air supply and exhaust sounds. It is understood that in other embodiments, the air supply device 3 and the air exhaust device 4 may also be located on the outside of the mattress. In this case, the covering layer 5 does not cover the air supply device 3 and the air exhaust device 4.

[0108] The intake valve 300 and the exhaust device 4 can be, for example, solenoid valves.

[0109] In some embodiments, such as Figure 23As shown, the airbag 20 has an inlet end 22 and an outlet end 21 with connectors 23 for connecting to an air pipe, facilitating connection of the inlet valve 300 and the exhaust device 4 via the air pipe. In other embodiments, the airbag 20 has rigid end caps 24 at its inlet end 22 and outlet end 21, and the end caps 24 have connectors 23 for connecting to an air pipe, facilitating connection of the inlet valve 300 and the exhaust device 4 via the air pipe. Of course, other methods can also be used in the art to connect the airbag 20 to the inlet valve 300 and the exhaust device 4.

[0110] In some embodiments, such as Figure 22 As shown, the mattress also includes a controller 40 and a pressure sensor 41 for detecting the air pressure of the airbag 20. Optionally, the pressure sensor 41 is at least partially located inside the airbag 20 for more accurate detection of the air pressure. The pressure sensor 41, the exhaust device 4, the intake valve 300, and the air pump 31 are all electrically connected to the controller 40. The controller 40 can control the intake valve 300 and the exhaust device 4 to operate according to the user's active operation, thereby adjusting the firmness of the mattress. The controller 40 can also control the intake valve 300 and the exhaust device 4 to operate according to the detection results of the pressure sensor 41, automatically adjusting the firmness of the mattress according to the internal program.

[0111] In addition to ensuring that the airbag 20 is accurately inflated and deflated to the required pressure range, the air pressure sensor 41 can also determine human activity through its signal characteristics. For example, it can determine whether a person is currently active or asleep, measure a person's heart rate when the person is relatively quiet, and detect movements such as turning over or twitching.

[0112] Understandably, the distribution of the airbags 20 determines the firmness of the mattress. In some embodiments, the airbags 20 are distributed throughout the entire elastic support 1, allowing for adjustment of the overall support performance of the mattress. In other embodiments, the airbags 20 are located in the middle of the mattress, with no airbags 20 at either end. Figure 25 The approximate location of the airbag support module 2 is indicated by a dotted line. Optionally, the length L1 of the airbag support module 2 should not be less than 45% of the length L2 of the mattress. Taking a 2m long mattress as an example, a 90cm long airbag support module 2 can be set in the middle of the mattress, and no airbag support module 2 can be set in the front and back 55cm positions. Figure 7 , Figure 9 and Figure 10As shown, the length L1 and width W1 of the airbag support module 2 refer to the distance between the outer edges of the two outermost support parts 200 in the width and length directions, respectively. Since the mattress is primarily supported in the middle area during rolling over, with the ends mainly supporting the head and legs and requiring less support, a central airbag support module 2, no less than 45% of the mattress's length L2, can meet the support requirements for rolling over. Optionally, the airbag support module 2 can be no more than 75% of the mattress's length L2 to reduce the length of the airbag 20, lowering costs. Furthermore, a shorter airbag 20 results in a smaller volume, allowing for faster adjustment of the mattress's firmness.

[0113] Understandably, since the airbag 20 does not cover the entire mattress, the support performance of different parts of the mattress will vary. Optionally, the airbag 20 can be pre-inflated with some gas to make the support performance of each part of the mattress basically the same, thereby improving the user experience.

[0114] Optional, in double beds, such as Figure 26 As shown, two sets of airbag support modules 2 can be used. The air pressure of the two sets of airbag support modules 2 can be adjusted independently. For example, each set of airbag support modules 2 can be equipped with a corresponding air supply device 3 and an air exhaust device 4 to adjust the firmness of the left and right sides of the mattress respectively, so as to adapt to the different needs of two people. Figure 26 The dashed lines in the diagram indicate the positions of the two airbag support modules 2.

[0115] It should be noted that, in the absence of conflict, the various embodiments described herein can be combined with each other to obtain more implementation schemes.

[0116] The above are merely specific embodiments of this utility model. Any improvements made based on the concept of this utility model shall be considered within the scope of protection of this utility model.
