Description

Technical Field

[0001] This invention relates to the field of bedding, specifically to an air cushion and mattress. Background Technology

[0002] Existing mattresses include a mattress body and an outer cover that encloses the mattress body. The mattress body contains an air cushion, which comprises densely arranged unit air cushions. Adjacent unit air cushions within the same area are interconnected and their air pressure is regulated by an air pressure regulating component. This allows for precise adjustment of the firmness of different areas of the air cushion, ensuring that the air cushion provides appropriate support to different parts of the user's body and conforms to the surface of each part of the user's body, effectively increasing the contact area and thus improving lying comfort. Existing air pressure regulating components include air tubes and solenoid valves matched to each unit air cushion. By controlling the opening and closing of the solenoid valves, the connection and disconnection of each unit air cushion are controlled, thereby regulating the air pressure within the unit air cushion.

[0003] Because there is no space on the airbag cushion for solenoid valves, the solenoid valves corresponding to each unit bladder are all located in the control box outside the cushion body. Each solenoid valve needs to be connected to its corresponding unit bladder through a corresponding air tube. This results in a complex air tube layout structure that occupies a large volume within the cushion body. It also increases the diameter of the bundled tubing between the control box and the cushion body, making it prone to deformation and blockage due to bending under stress. This, in turn, affects the reliability of air pressure regulation within the corresponding unit bladder and impacts the user experience.

[0004] In addition, in order to simplify the tracheal structure, the number of independently adjustable areas was reduced. This resulted in a larger coverage area for each area, making it impossible to make precise and independent adjustments to smaller areas on the airbag cushion, or to make precise and independent adjustments to individual support units, thus affecting user comfort. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an airbag cushion and mattress with independently adjustable unit air pressure. A cavity is created between adjacent unit airbags within the airbag cushion, and an air tube and solenoid valve are housed within this cavity. This allows for independent adjustment of each unit airbag, improving the precision of firmness adjustment in the areas corresponding to each unit airbag on the airbag cushion. Furthermore, the cavity allows for the placement of the air tube and solenoid valve, with the solenoid valve connecting the air tube and unit airbag. Sharing the air tube simplifies the structure and facilitates processing, maintenance, and use.

[0006] This invention is achieved through the following method: an airbag cushion with independently adjustable unit air pressure, comprising a plurality of closely arranged unit airbags, adjacent unit airbags being isolated from each other and enclosing each other to form a cavity for installing an air pressure regulating component, the air pressure regulating component comprising an air tube and a solenoid valve disposed on the air tube, the cavity comprising a receiving cavity formed by adjacent unit airbags and vertically penetrating, and a channel for laying air tubes through each receiving cavity in series, the solenoid valve being disposed in the receiving cavity and communicating with adjacent unit airbags, so that the air pressure in each unit airbag can be independently adjusted through the corresponding solenoid valve. A cavity is set between adjacent unit bladders within the airbag cushion, and an air tube is laid along the cavity. A solenoid valve is set in the receiving cavity. The air tube can pass through each receiving cavity in sequence and connect with each unit bladder through the solenoid valve. This allows for independent adjustment of each unit bladder, improving the softness and hardness adjustment accuracy of the independent corresponding area on the airbag cushion. It also utilizes the reserved receiving cavity to provide installation space for the solenoid valve, ensuring that the air tube is independently connected to each unit bladder along the way through the solenoid valve. The shared air tube simplifies the structure, making it easier to process, maintain, and use. Furthermore, the deformation adjustment accuracy is improved by reducing the area of ​​the independently adjustable region, thus enhancing the user experience.

[0007] Preferably, the unit bladders are arranged in a matrix. Unit bladders on the same straight line are interconnected to form bladder strips. The bladder strips are arranged parallel to each other and form channels along their length. The four adjacent unit bladders of adjacent bladder strips enclose each other to form the receiving cavity. The air tube includes an inflation tube connected to an external air source and an exhaust tube connected to the external space. The inflation tube and exhaust tube are laid along the channels and connected to each unit bladder along the way through a solenoid valve. The bladder strips are long and strip-shaped with undulating sidewalls. Adjacent bladder strips are parallel to each other and are enclosed by the undulating sidewalls to form the channels and receiving cavities, providing installation space for the air tubes and solenoid valves. The receiving cavity is used to install the solenoid valves and air tubes, and also runs vertically through the space to improve breathability. This allows moisture and sweat generated by the human body to diffuse downwards and outwards through the receiving cavity, ensuring that the user's surface is dry and improving comfort. Each unit capsule is equipped with an exhaust pipe and an inflation pipe along its edge, allowing for separate exhaust and inflation operations. Since the exhaust and inflation pipes can be used to perform exhaust and inflation operations on each unit capsule along both sides of the route, the number of air pipes can be reduced by sharing the air pipes, thereby simplifying assembly and making it easier to use and maintain.

[0008] Preferably, the exhaust pipe extends towards one end of the airbag strips and is bundled together to connect with the external space, while the inflation pipe extends towards the other end of the airbag strips and is bundled together to connect with an external air source. The exhaust pipe and inflation pipe extend towards both sides of the airbag pad and are bundled together to connect with a predetermined target object. This effectively utilizes the space at both sides of the airbag pad and prevents the exhaust pipe and inflation pipe from becoming entangled due to concentrated laying, facilitating assembly and maintenance. The exhaust pipe, after being bundled together towards one side of the airbag pad, connects to the external space, allowing air from each unit airbag to be discharged to the outside space, thus reducing the air pressure inside the unit airbag. The inflation pipe, after being bundled together towards the other side of the airbag pad, connects to the control box, supplying high-pressure air to each unit airbag to increase the air pressure inside the unit airbag. Two rows of airbag strips share one exhaust pipe and one inflation pipe, resulting in multiple exhaust pipes and inflation pipes on the airbag pad. These exhaust pipes and inflation pipes are bundled together when laid along the corresponding side edges of the airbag pad.

[0009] Preferably, the solenoid valve includes an inflation valve mounted on the inflation pipe and an exhaust valve mounted on the exhaust pipe. The inflation pipe and exhaust pipe are alternately laid within the channel. Each unit bladder can be connected to its corresponding inflation valve and exhaust valve via inflation nozzles and exhaust nozzles located in its side accommodating cavities, respectively, so that the air pressure inside each unit bladder can be independently adjusted. The inflation valve is located between the inflation pipe and the corresponding unit bladder and is used to control the connection between the inflation pipe and the unit bladder to perform the inflation operation; the exhaust valve is located between the exhaust pipe and the corresponding unit bladder and is used to control the connection between the exhaust pipe and the unit bladder to perform the exhaust operation. The airbag cushion comprises multiple parallel, spliced ​​airbag strips, giving the airbag cushion multiple parallel and equidistantly spaced channels. The inflation tube and deflation tube are alternately laid within the channels, ensuring that the inflation tube and deflation tube are set up separately and have corresponding channels, preventing them from getting tangled and facilitating assembly and maintenance. It also ensures that the inflation tube and deflation tube can be connected to the unit airbags on both sides of the channel, so that each unit airbag can be connected to the inflation tube and deflation tube on both sides and achieve independent air pressure adjustment.

[0010] Preferably, each receiving cavity in the channel is equipped with two inflation or deflation valves connected in series with the corresponding air tube. The receiving cavity is formed by four unit bladders arranged in a matrix. Each receiving cavity through which the air tube passes is connected to a unit bladder on one of the two side bladder strips through two solenoid valves, ensuring that each receiving cavity has the same number of solenoid valves, which facilitates processing and maintenance.

[0011] Preferably, the receiving cavity is equipped with four inflation or deflation valves connected in series on the corresponding air tubes, so that the solenoid valves are spaced apart along the receiving cavity in the channel. The receiving cavity is formed by four unit capsules arranged in a matrix. The four solenoid valves are installed in the receiving cavity. The solenoid valves are connected to the air tubes and also communicate with the four unit capsules that form the receiving cavity. This effectively improves the space utilization efficiency of the receiving cavity and eliminates the need to install solenoid valves in each receiving cavity. The components with the corresponding number of solenoid valves are pre-assembled and integrated before being installed into the corresponding receiving cavities, which facilitates assembly and maintenance.

[0012] Preferably, the solenoid valve is a two-position two-way valve, including a first port connected to the trachea and a second port connected to the corresponding unit capsule. The solenoid valve can switch between an open state where the first port and the second port are connected and a closed state where the first port and the second port are disconnected. This ensures that the solenoid valve can connect the unit capsule to the corresponding trachea when it is switched to the open state, and can also disconnect the unit capsule from the corresponding trachea when it is switched to the closed state. During use, the trachea remains unobstructed and will not be blocked due to the opening and closing of the solenoid valve, ensuring that the trachea can be shared by all solenoid valves along the route.

[0013] Preferably, the inflation pipe and the exhaust pipe share the same channel and are connected to the pressure regulating nozzle on the corresponding unit bladder via the solenoid valve. The solenoid valve is a three-position three-way valve, including an inflation port connected to the inflation pipe, an exhaust port connected to the exhaust pipe, and a pressure regulating port connected to the pressure regulating nozzle. The solenoid valve can switch between an inflation state where the inflation port and the pressure regulating port are connected, an exhaust state where the exhaust port and the pressure regulating port are connected, and a pressure holding state where the inflation port, the exhaust port, and the pressure regulating port are isolated from each other. The inflation pipe and the exhaust pipe are laid in the same channel and can be connected to each unit bladder on both sides of the channel via the solenoid valve, thereby enabling independent pressure regulation of each unit bladder. When the solenoid valve is switched to the inflation state, the inflation port is connected to the pressure regulating port and disconnected from the exhaust port, thus inflating the unit bladder; when the solenoid valve is switched to the exhaust state, the inflation port is disconnected from the pressure regulating port and connected to the exhaust port, thus venting the unit bladder; when the solenoid valve is switched to the pressure holding state, the inflation port is disconnected from the pressure regulating port and disconnected from the exhaust port, thus holding the pressure in the unit bladder to ensure that the air pressure inside the unit bladder remains constant.

[0014] Preferably, the cavity is provided with four solenoid valves that are respectively connected to the adjacent unit bladders. The four solenoid valves are centrally located in one cavity and are respectively connected to the four unit bladders that enclose the cavity. The integrated arrangement of the solenoid valves facilitates disassembly and maintenance.

[0015] Preferably, the inflation tubes are spaced apart in the cavity. Since the inflation and deflation tubes can communicate with the unit bladders on both sides of the channel, air tubes can be spaced apart in each channel on the airbag cushion, effectively simplifying the pipeline structure and facilitating assembly and maintenance.

[0016] Preferably, the unit capsule is cylindrical, so that the cavity formed by the unit capsule is cylindrical, which increases the size of the cavity opening, facilitates the disassembly and assembly of the air pressure regulating component, and also improves the breathability and moisture wicking effect.

[0017] Preferably, the unit bladder has a square cross-section, with its diagonals arranged along the length of the bladder strip, so that adjacent unit bladders enclose a square-shaped receiving cavity. This utilizes unit bladders with their diagonals aligned to form a rectangular receiving cavity, effectively increasing the proportion of the vertical projected area of ​​the receiving cavity to the vertical projected area of ​​the airbag cushion. This facilitates the installation of air pressure regulating components and improves moisture and perspiration wicking.

[0018] Preferably, the unit capsule has a circular cross-section, which reduces the production difficulty of the unit capsule, facilitates mass production, and also provides a four-pointed star-shaped cavity for the pressure regulating component, making assembly and maintenance convenient.

[0019] Preferably, an upward-facing, exposed partition groove is provided at the top of the connection between adjacent unit bladders, allowing the tops of adjacent unit bladders to move relatively independently. Adjacent unit bladders are connected and fixed to each other through the middle and bottom of the connection, thus fixing their relative positions. The partition groove at the top of the connection allows for separation, enabling the tops of each unit bladder to deform and move freely according to external forces. This facilitates fitting and conforming to the supported object, effectively reduces the tensile force between adjacent unit bladders, and thus ensures effective shaping of the airbag cushion.

[0020] A mattress includes a mattress body and an outer cover enclosing the mattress body. The mattress body includes an airbag cushion, a surrounding edge, a bottom pad located beneath the airbag cushion, and a comfort pad placed on top of the airbag cushion. The airbag cushion is connected to a control box external to the mattress body via air tubes. The airbag cushion is located in the center of the mattress body. Each airbag unit can independently adjust its air pressure to allow for independent firmness adjustment of the top surface of the mattress body and its corresponding area. This satisfies the user's need for firmness adjustment while ensuring that the top surface of the mattress body conforms to the user's surface, improving lying comfort. The surrounding edge horizontally limits the airbag cushion, the comfort pad can reduce the feeling of foreign objects by deforming itself, and the bottom pad provides effective support for the airbag cushion, preventing the bottom of the airbag unit from shifting downwards and improving the reliability of firmness adjustment.

[0021] The beneficial effects of this invention are as follows: A cavity is provided between adjacent unit bladders within the airbag cushion, and an air tube is laid along the cavity. An electromagnetic valve is located within the receiving cavity. The air tube can sequentially pass through each receiving cavity within the cavity and connect to each unit bladder via the electromagnetic valve. This allows for independent adjustment of each unit bladder, improving the precision of softness / hardness adjustment in the area corresponding to each unit bladder on the airbag cushion. Furthermore, the reserved receiving cavity provides installation space for the electromagnetic valve, ensuring independent communication between the air tube and each unit bladder along the route via the electromagnetic valve. The shared air tube simplifies the structure, facilitating processing, maintenance, and use. Additionally, reducing the area of ​​the independently adjustable region improves deformation adjustment precision and enhances the user experience. Attached Figure Description

Detailed Implementation The essential features of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: This embodiment provides an airbag cushion with independently adjustable unit air pressure.

[0024] like Figure 1 The airbag shown includes several closely arranged unit bladders 2. Adjacent unit bladders 2 are isolated from each other and enclose each other to form a cavity for the installation of an air pressure regulating component. The air pressure regulating component includes an air tube and a solenoid valve installed on the air tube. The cavity includes a receiving cavity 3 formed by adjacent unit bladders 2 and vertically connected, and a channel 4 through which the air tubes are laid and connected in series with each receiving cavity 3. The solenoid valve is installed in the receiving cavity 3 and communicates with the adjacent unit bladder 2 so that the air pressure in each unit bladder 2 can be independently adjusted by the corresponding solenoid valve. A cavity is set between adjacent airbag strips 1 within the airbag cushion, and an air tube is laid along the cavity. A solenoid valve is set in the receiving cavity 3. The air tube can pass through each receiving cavity 3 in sequence and connect with each unit airbag 2 through the solenoid valve. This allows for independent adjustment of each unit airbag 2, improving the accuracy of softness and hardness adjustment in each area of ​​the airbag cushion. It also utilizes the reserved receiving cavity 3 to provide installation space for the solenoid valve, ensuring that the air tube is independently connected to each unit airbag 2 along the way through the solenoid valve. The shared air tube simplifies the structure, facilitates processing, maintenance and use, and improves the user experience.

[0025] In this embodiment, the unit capsules 2 are arranged in a matrix. Unit capsules 2 on the same straight line are connected to each other to form capsule strips 1. The capsule strips 1 are arranged parallel to each other and form channels along their length. The capsule strips 1 are formed by connecting the linearly arranged unit capsules 2, so that the capsule strips 1 have undulating sidewalls. Adjacent capsule strips 1 are spliced ​​in parallel and enclosed by the undulating sidewalls to form the cavity, providing installation space for the air pressure regulating component. Channels 4 are formed between adjacent capsule strips 1 along their length. The four adjacent unit capsules 2 of adjacent capsule strips 1 enclose the receiving cavity 3. The channel 4 is used for laying the air tube, and the receiving cavity 3 is used to install the solenoid valve, so that each unit capsule 2 is connected to the air tube through the corresponding solenoid valve to realize independent air pressure regulation.

[0026] In this embodiment, a notch 22 is provided on the contact area of ​​the corresponding sidewall of the adjacent bladder strip 1 (e.g., Figure 8 As shown), the notches 22 are opened in the equal-height sections of the sidewalls of each unit capsule 2 within the same capsule strip 1. Adjacent capsule strips 1 are joined together and enclosed by the corresponding notches 22 to form a straight channel 4 (as shown). Figure 9 and 11 (As shown). Specifically, the opposing walls of adjacent airbag strips 1 are provided with contact areas, and the corresponding contact areas are tightly bonded together to form an airbag cushion. The corresponding contact areas are fixed together by heat fusion or adhesive bonding, which should be regarded as specific implementation of this embodiment.

[0027] In this embodiment, the air pipe includes an inflation pipe 5 connected to an external air source and an exhaust pipe 6 connected to the external space. The inflation pipe 5 and the exhaust pipe 6 are laid along the channel 4 and connected to each unit bladder 2 along the way via a solenoid valve. The exhaust pipe 6 connects to the external space, ensuring that the air inside the unit bladder 2 can be discharged to the external space through the exhaust pipe 6, thereby reducing the air pressure inside the unit bladder 2. The inflation pipe 5 connects to the external air source, typically a control box 17, ensuring that the unit bladder 2 receives high-pressure air generated by the control box 17, thereby increasing the air pressure inside the unit bladder 2. The unit bladder 2 is connected to both the exhaust pipe 6 and the inflation pipe 5, allowing the air pressure inside the unit bladder 2 to be independently and precisely adjusted as needed. This results in differentiated and independently adjustable firmness in different areas of the airbag cushion to meet usage requirements and improve user comfort.

[0028] In this embodiment, the airbag cushion includes several airbag strips 1, which are joined together to form multiple parallel channels 4. The exhaust pipe 6 and the inflation pipe 5 are alternately arranged on the channels 4 on the airbag cushion. Specifically, the channels 4 are sequentially arranged, with the exhaust pipe 6 located on odd-numbered channels 4 (first, third, fifth, etc.) and the inflation pipe 5 located on even-numbered channels 4 (second, fourth, sixth, etc.). This separate arrangement of the exhaust pipe 6 and inflation pipe 5 prevents entanglement and ensures that each airbag strip 1 has an exhaust pipe 6 and an inflation pipe 5 on both sides. This allows the unit airbags 2 on the airbag strip 1 to be inflated and deflated respectively by connecting to the exhaust pipes 6 and inflation pipes 5 on both sides, facilitating effective control of the air pressure inside each unit airbag 2.

[0029] In this embodiment, the exhaust pipe 6 extends to one end of the airbag strip 1 and is bundled together to connect with the external space. The inflation pipe 5 extends to the other end of the airbag strip 1 and is bundled together to connect with an external air source. The exhaust pipe 6 and the inflation pipe 5 are laid on both sides of the airbag pad. The exhaust pipes 6 located on the same side edge of the airbag pad are bundled together and laid along a unified path to connect with the external space. The inflation pipes 5 located on the other side edge of the airbag pad are bundled together and laid along a unified path to connect with the control box 17. This facilitates laying, simplifies the structure, and prevents tangling and knotting, ensuring that each air pipe maintains a smooth air path.

[0030] In this embodiment, the solenoid valve includes an inflation valve 8 disposed on the inflation pipe 5 and an exhaust valve 7 disposed on the exhaust pipe 6. The inflation pipe 5 and the exhaust pipe 6 are alternately laid in the channel 4. Each unit bladder 2 can be connected to the corresponding inflation valve 8 and exhaust valve 7 through inflation nozzles 20 and exhaust nozzles 21 disposed in the receiving cavities 3 on both sides, so that the air pressure in each unit bladder 2 can be adjusted independently. The section of the air pipe located in the receiving cavity 3 is connected to the corresponding unit bladder 2 through a series of solenoid valves, and the air pressure in the unit bladder 2 is adjusted by controlling the connection and disconnection relationship between the control bladder 2 and the air pipe. Specifically, the section of the inflation pipe 5 located in the receiving cavity 3 is connected to the corresponding unit bladder 2 through a series of inflation valves 8, and the unit bladder 2 is inflated by controlling the connection and disconnection relationship between the control bladder 2 and the inflation pipe 5; the section of the exhaust pipe 6 located in the receiving cavity 3 is connected to the corresponding unit bladder 2 through a series of exhaust valves 7, and the unit bladder 2 is vented by controlling the connection and disconnection relationship between the control bladder 2 and the air pipe.

[0031] In this embodiment, each receiving cavity 3 on the channel 4 is provided with two exhaust valves 7 or inflation valves 8 connected in series on the corresponding air pipe. An inflation nozzle 20 and an exhaust nozzle 21 are respectively provided on the same side of the end of the unit bladder 2. The inflation nozzle 20 is connected to the inflation pipe 5 through the inflation valve 8, and the exhaust nozzle 21 is connected to the exhaust pipe 6 through the exhaust valve 7. This allows each receiving cavity 3 to be equipped with two exhaust valves 7 or two inflation valves 8 depending on the type of air pipe inserted (e.g., ...). Figure 2 As shown in the figure, the number of solenoid valves in each cavity 3 is limited to ensure air permeability and improve the moisture removal effect of the airbag.

[0032] In this embodiment, the solenoid valve is a two-position two-way valve (e.g., Figure 3 As shown), it includes a first port 9 connected to the trachea and a second port 10 connected to the corresponding unit sac 2. The solenoid valve can switch between an open state where the first port 9 and the second port 10 are connected and a closed state where the first port 9 and the second port 10 are disconnected. When the solenoid valve is switched to the closed state (e.g. Figure 4 As shown), unit bladder 2 is disconnected from the trachea to ensure that unit bladder 2 effectively maintains the existing air pressure. When the solenoid valve switches to the open state (e.g. Figure 5 As shown in the diagram, unit bladder 2 is connected to the trachea, thereby enabling inflation or deflation operations. The solenoid valve is connected in series with the trachea, ensuring that the trachea remains unobstructed and can be shared by all the solenoid valves on it, effectively improving the utilization efficiency of the trachea, simplifying the pipeline structure, and facilitating assembly and maintenance.

[0033] In this embodiment, the unit capsule 2 is columnar, so that the receiving cavity 3 formed by the unit capsule 2 is columnar, and the cross-section of the unit capsule 2 is square (e.g., Figure 6 and 7 As shown), the diagonal of the unit capsule 2 is arranged along the length of the capsule strip 1, so that adjacent unit capsules 2 enclose and form a receiving cavity 3 with a square cross-section. Within the same capsule strip 1, the unit capsules 2 form undulating sidewalls by being tightly joined together, and then form a cavity by being joined together facing each other. In addition, the cross-section of the unit capsule 2 is circular (as shown). Figure 10 (As shown), it should also be regarded as a specific implementation of this embodiment.

[0034] Understandably, the unit capsule 2 can be modified to form unit modules of other shapes, so that the relative positions of adjacent unit capsules 2 are fixed and remain isolated and independent from each other. This facilitates assembly to form an airbag cushion, allows for independent air pressure adjustment of each unit capsule, and also provides the cavity. This should also be considered a specific implementation of this embodiment. The unit module preferably has a square structure with a 2x2, 3x3, or 4x4 layout, or a rectangular structure with a 2x3, 2x4, 3x4, or 3x6 layout.

[0035] Understandably, the corresponding sidewalls of adjacent capsule strips 1 can be connected by connecting pieces 23 (e.g., Figure 12 As shown), connecting pieces 23 are intermittently arranged on the side wall of the bag strip 1 to form the notches 22 between adjacent connecting pieces 23, thereby using the corresponding notches 22 to enclose and form the channel 4 (as shown). Figure 13 (As shown), it should also be regarded as a specific implementation of this embodiment.

[0036] Example 2: Compared to Embodiment 1, this embodiment provides another type of airbag cushion.

[0037] like Figure 14 As shown, the receiving cavity 3 is equipped with four exhaust valves 7 or inflation valves 8 connected in series on corresponding air pipes, so that the solenoid valves are spaced apart along the receiving cavity 3 on the channel 4. The four unit bladders 2 arranged in a matrix can enclose a receiving cavity 3. The four exhaust nozzles 21 or four inflation nozzles 20 on the four unit bladders 2 are located in the same receiving cavity 3 and connected to the exhaust pipe 6 or inflation pipe 5 passing through the receiving cavity 3, so that the solenoid valves can be laid in a centralized manner, which not only facilitates the laying of control circuits, but also facilitates assembly and maintenance by pre-processing the components including the four solenoid valves.

[0038] In this embodiment, multiple consecutively arranged receiving cavities 3 are provided between adjacent bladder strips 1. The receiving cavities 3 are numbered sequentially. Solenoid valves are provided in the odd-numbered receiving cavities 3 (first, third, fifth, etc.), while no solenoid valves are provided in the even-numbered receiving cavities 3 (second, fourth, sixth, etc.). Furthermore, providing solenoid valves in even-numbered receiving cavities 3 and not providing solenoid valves in odd-numbered receiving cavities 3 should also be considered a specific implementation of this embodiment.

[0039] In this embodiment, the four solenoid valves within the same accommodating cavity 3 are connected in series on their corresponding air pipes (e.g., Figure 15 As shown, the trachea remains unobstructed, ensuring that it can be shared by solenoid valves along the route. The first port 9 of the solenoid valve is connected to the trachea, and the second port 10 is connected to the corresponding unit bladder 2. The solenoid valve switches between open and closed states to switch the connection between the trachea and the corresponding unit bladder 2, thereby enabling independent air pressure regulation for each unit bladder 2.

[0040] The other structures and effects of the airbag cushion described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0041] Example 3: Compared to Embodiment 1 or 2, this embodiment provides another type of airbag cushion.

[0042] like Figure 16 and 19 As shown, the inflation pipe 5 and the exhaust pipe 6 share the same channel 4 and are connected to the pressure regulating nozzle 19 on the corresponding unit bladder 2 via the solenoid valve. The solenoid valve is a three-position three-way valve. The exhaust pipe 6 and the inflation pipe 5, which pass through the same cavity, are connected to the corresponding unit bladder 2 via a solenoid valve (e.g., Figure 21As shown), this allows unit bladder 2 to perform inflation, deflation, and pressure holding operations in a staggered manner via a single solenoid valve. This simplifies the pipeline structure by reducing the number of solenoid valves, facilitating assembly and maintenance, and also ensures that each unit bladder 2 can independently adjust its air pressure. During installation, each unit bladder 2 is equipped with one solenoid valve, and the deflation pipe 6 and inflation pipe 5 used with the same unit bladder 2 are both located in the same cavity (e.g., Figure 22 As shown in the figure, it is convenient to connect and use with a solenoid valve.

[0043] In this embodiment, as Figure 20 As shown, a partition groove 24 is provided at the top of the connection between adjacent unit bladders 2. The partition groove 24 is exposed upwards. The tops of adjacent unit bladders 2 are independent of each other and can be independently stretched, extended, and twisted. This allows the tops of each unit bladder 2 to be independently adjusted according to the force applied. This effectively increases the freedom of movement of the tops of the unit bladders 2, making it easier to match and fit the supported object through deformation, thus improving support comfort. It also effectively limits the traction between adjacent unit bladders 2, ensuring that the relative positions between adjacent unit bladders 2 remain fixed, thereby effectively maintaining the contour of the airbag and providing stable support for the user.

[0044] In this embodiment, the receiving cavity 3 is provided with four solenoid valves respectively connected to adjacent unit bladders 2, and the inflation pipes 5 are spaced apart in the cavity. The solenoid valve includes an inflation port 11 connected to the inflation pipe 5, an exhaust port 12 connected to the exhaust pipe 6, and a pressure regulating port 13 connected to the pressure regulating nozzle 19. The solenoid valve can switch between an inflation state where the inflation port 11 and the pressure regulating port 13 are connected, an exhaust state where the exhaust port 12 and the pressure regulating port 13 are connected, and a pressure holding state where the inflation port 11, the exhaust port 12, and the pressure regulating port 13 are isolated from each other. Because the solenoid valve has an inflation port 11, an exhaust port 12, and a pressure regulating port 13, it can simultaneously perform inflation, exhaust, and pressure holding operations. After installation, the solenoid valve can be installed in either the odd-numbered or even-numbered receiving cavities 3 of the same channel, or in either the odd-numbered or even-numbered cavities of the same airbag. This allows the airbag to install solenoid valves in only one-quarter of its receiving cavities 3, effectively reducing the number of solenoid valves, thereby simplifying the pipeline structure and facilitating assembly and maintenance.

[0045] In this embodiment, both the exhaust pipe 6 and the inflation pipe 5 are straight within the receiving cavity 3, because the inflation port 11 and the exhaust port 12 of the solenoid valve have different orientations. During installation, the inflation ports 11 of the solenoid valve are directly connected to the straight inflation pipe 5, effectively reducing the flow resistance of high-pressure air and improving inflation efficiency. The exhaust ports 12 of the solenoid valve have different orientations (e.g., Figure 18 As shown), the pressure regulating port 13 also has different orientations, and the exhaust port 12 of the solenoid valve is connected to the exhaust pipe 6 through an exhaust branch pipe (as shown). Figure 17As shown, this ensures smooth gas discharge and allows the exhaust port 12 to be set in any direction as needed, making it convenient for the pressure regulating port 13 to be connected to the pressure regulating nozzle 19 on the corresponding unit bladder 2 through the pressure regulating branch pipe, thus making reasonable use of the space inside the accommodating cavity 3.

[0046] The other structures and effects of the airbag cushion described in this embodiment are the same as those in Embodiment 1 or 2, and will not be repeated here.

[0047] Example 4: Compared to Embodiment 1, 2, or 3, this embodiment provides a mattress.

[0048] like Figure 23 The mattress shown includes a mattress body and an outer cover enclosing the mattress body. The mattress body includes an airbag cushion 18, a surrounding edge 14 around the airbag cushion 18, a base pad 15 located below the airbag cushion 18, and a comfort pad 16 laid on top of the airbag cushion 18. The airbag cushion 18 is connected to a control box 17 located outside the mattress body via air tubes. The airbag cushion 18 is located in the middle of the mattress body. Each unit 2 can adjust its air pressure independently to allow the firmness of corresponding areas on the top surface of the mattress body to be adjusted synchronously. This not only meets the user's needs for adjusting the firmness of the mattress body but also ensures that the top surface of the mattress body can match and conform to the user's surface, improving lying comfort.

[0049] In this embodiment, the perimeter 14 is annular and surrounds the airbag cushion 18, providing horizontal restraint to the airbag cushion 18. The vertical projection of the comfort pad 16 completely covers the top surface of the pad body, utilizing the deformation of the comfort pad 16 itself to reduce the feeling of foreign objects and improve lying comfort. The bottom pad 15 provides effective support for the airbag cushion 18, preventing the bottom of the unit bladder 2 from shifting downwards and improving the reliability of the firmness adjustment.

[0050] The other structures and effects of the airbag cushion described in this embodiment are the same as those in Embodiments 1, 2, or 3, and will not be repeated here.
