Description

Technical Field

[0001] This utility model relates to the technical field of sofa inflation, and in particular to a pressure-maintaining gas regulating cavity assembly and a solenoid valve regulating assembly. Background Technology

[0002] In modern industrial and automated control systems, especially in the field of pneumatic control, such as air pump inflation systems for sofa cushions, precise control of the flow of fluid media (such as gas) is crucial. These systems often need to implement multi-mode functions, including but not limited to pressure maintenance, flow regulation, and direction control, to meet different application scenarios and user needs.

[0003] However, traditional gas control designs often rely on multiple independent control components, such as solenoid valves, to achieve these functions. These components are distributed and interconnected through complex piping and connectors. This distributed layout presents several challenges. First, the dispersed installation of multiple solenoid valves and other control components results in a large system footprint, increasing the size and weight of the equipment. This is a significant disadvantage for modern industrial equipment that strives for miniaturization and lightweight design.

[0004] Secondly, due to the large number and wide distribution of parts, the production and assembly process becomes extremely cumbersome, which not only increases manufacturing costs but also prolongs assembly time and reduces production efficiency. Furthermore, the complex piping connections increase the risk of system malfunctions, such as gas leaks and loose connections, causing significant inconvenience for later maintenance and upkeep. Utility Model Content

[0005] In order to overcome at least one of the defects described in the prior art, the present invention provides a pressure-holding gas regulating chamber assembly and a solenoid valve regulating assembly.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A pressure-holding gas regulating chamber assembly includes: a guide chamber, the guide chamber comprising linearly arranged transfer chambers and at least one airbag chamber, each airbag chamber having an airbag interface, and the transfer chamber having a transfer valve interface; an air inlet channel, the air inlet channel extending from the transfer chamber through the airbag chambers to form an air inlet interface; a venting channel, the venting channel extending from the transfer chamber through the airbag chambers to form a venting interface; and a pressure-holding chamber, the pressure-holding chamber being linearly integrated with the guide chamber and disposed within the transfer chamber. On the side away from the airbag cavity, the pressure-holding cavity includes a first interface and a second interface, the first interface being connected to the transfer valve interface; a control component, the control component including a transfer cavity control component, an airbag cavity control component, and a pressure-holding cavity control component, the transfer cavity control component being used to control the connection between the transfer cavity and the air intake channel or the air release channel, the airbag cavity control component being used to control the connection between the airbag cavity and the air intake channel or the air release channel, and the pressure-holding cavity control component being used to control the gas flow direction within the first interface and the second interface.

[0008] By adopting the above solution, the space required for dispersing control components is reduced through the linear integration of the transfer chamber, airbag chamber, and pressure-holding chamber. This makes the entire system more compact, thereby reducing the size and weight of the equipment and simplifying production and assembly. Furthermore, the simpler and clearer structure makes subsequent maintenance and upkeep easier.

[0009] Furthermore, the control component is a solenoid valve.

[0010] By adopting the above scheme, the solenoid valve achieves switching control through electromagnetic principles, enabling it to respond quickly to control signals and accurately control parameters such as gas flow and pressure, thus ensuring the stability of the production process.

[0011] Furthermore, it also includes a muffler, which is connected to the vent port.

[0012] By adopting the above solution, the sound waves generated during inflation and deflation can be effectively absorbed and reflected, thereby reducing the noise level.

[0013] Furthermore, the air intake channel and the air vent channel are spaced apart, and the gas flows through them alternately.

[0014] By adopting the above scheme, the interval setting can ensure that the gases do not interfere with each other during the flow process, thereby improving the gas flow efficiency, helping to reduce the resistance and pressure loss of the gas in the channel, and enabling the gas to enter and exit the cavity assembly more smoothly.

[0015] Furthermore, when air enters through the air intake port, the gas flows sequentially through the transfer valve port and the first port along the air intake channel and then flows out through the second port.

[0016] By adopting the above scheme, the pressure and flow of gas are controlled by adjusting the opening of the control component, which helps to avoid chaotic gas flow inside the cavity, thereby improving the control accuracy and stability of the gas.

[0017] Furthermore, when the venting port is vented, gas flows into the venting channel from the second port and the airbag port and flows out from the venting port.

[0018] By adopting the above scheme, the gas can flow more flexibly during the venting process, which helps to optimize gas management. In scenarios where precise control of gas emission is required, the venting rate can be precisely controlled by adjusting the opening degree of the second interface and the airbag interface.

[0019] An electromagnetic valve control assembly employs a pressure-holding gas control chamber assembly, comprising: an assembly housing, wherein the control component is assembled within the assembly housing; a first flow guide connected to the assembly housing; a second flow guide connected to the first flow guide, wherein the pressure-holding chamber is disposed within the second flow guide, and the airbag interface, transfer valve interface, air inlet interface, first interface, and second interface all extend through the second flow guide.

[0020] By adopting the above scheme, the integrated setup achieves structural compactness. This not only reduces the floor space but also improves component integration, making the entire system simpler and more efficient. The optimized gas flow path through the pressure-holding gas regulation chamber component helps reduce energy consumption and costs. Precise control of the control components reduces unnecessary energy loss and waste.

[0021] Furthermore, the first flow guide is detachably connected to the second flow guide, and / or the first flow guide is detachably connected to the assembly housing.

[0022] By adopting the above solution, the first flow guide, the second flow guide, and the components between the assembly housing can be easily disassembled and reinstalled. This greatly simplifies the maintenance and replacement process, reduces maintenance costs, and improves work efficiency.

[0023] Furthermore, the first guide member is provided with a first connecting post, the second guide member is provided with a second connecting post, and a fastener is provided between the first connecting post and the second connecting post.

[0024] By adopting the above solution, a solid connection between the first and second flow guides is ensured, which not only helps prevent gas leakage but also guarantees the stable operation of the component in high-pressure or high-flow-rate gas environments.

[0025] Furthermore, the first guide member is provided with a snap-fit ​​protrusion, and the assembly housing is provided with a snap-fit ​​groove, wherein the snap-fit ​​protrusion and the snap-fit ​​groove are fixedly connected.

[0026] By adopting the above solution, the disassembly process is made simpler and maintenance efficiency is improved. At the same time, the tight fit between the snap-fit ​​protrusion and the snap-fit ​​groove helps to prevent gas leakage and component loosening.

[0027] In summary, the pressure-holding gas regulating chamber assembly and the solenoid valve regulating assembly provided by this utility model have the following technical effects:

[0028] 1. By linearly integrating the transfer chamber, air bladder chamber, and pressure holding chamber, the space required for distributed control components is significantly reduced. This compact design makes the entire system smaller, reducing the size and weight of the equipment, making it particularly suitable for modern industrial and automated control systems with strict space requirements;

[0029] 2. The integrated design of components simplifies the production and assembly process, reduces the number of parts and assembly steps, thereby lowering manufacturing costs and assembly time. This design improves production efficiency, enabling the system to be brought to market faster and meet user needs.

[0030] 3. The compact structure and high degree of integration help reduce the risk of gas leakage and loose connections, improving the stability and reliability of the system. Meanwhile, precise control of the components ensures the accuracy and stability of gas flow, meeting the needs of different application scenarios and users.

[0031] 4. By optimizing the gas flow path and precisely controlling the components, this assembly helps reduce energy consumption and costs. It reduces unnecessary energy loss and waste, improving the system's economics and sustainability. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0041] See Embodiment 1 of this utility model. Figures 1-4As shown, a pressure-holding gas regulating chamber assembly is disclosed, including a guide chamber 1, an air inlet channel 2, a gas release channel 3, a pressure-holding chamber 4, and a control component 5. The guide chamber 1 includes a linearly arranged transfer chamber 11 and at least one airbag chamber 12. Preferably, there are three airbag chambers 12, each with an airbag interface 121 for connecting to an airbag in a sofa cushion. The airbags in the sofa cushion include, but are not limited to, leg airbags, seat airbags, lumbar support airbags, or back airbags. The transfer chamber 11 is provided with a transfer valve interface 111. The air inlet channel 2 extends from the transfer chamber 11 through the airbag chambers 12 to form the air inlet interface 21, which is used to connect to an air pump for inflation. The gas release channel 3 extends from the transfer chamber 11 through the airbag chambers 12 to form the gas release interface 31. The pressure-holding chamber 4 is linearly connected to the guide chamber 1. The control components are integrated into one unit and located on the side of the transfer chamber 11 away from the airbag chamber 12. The pressure-holding chamber 4 includes a first interface 41 and a second interface 42. The first interface 41 is connected to the transfer valve interface 111, and the second interface 42 is used to connect to the airbag of the sofa cushion, preferably a lumbar support airbag. The control component 5 includes a transfer chamber control component 51, an airbag chamber control component 52, and a pressure-holding chamber control component 53. The transfer chamber control component 51 is used to control the connection between the transfer chamber 11 and the air intake channel 2 or the air release channel 3. The airbag chamber control component 52 is used to control the connection between the airbag chamber 12 and the air intake channel 2 or the air release channel 3. The pressure-holding chamber control component 53 is used to control the gas flow direction in the first interface 41 and the second interface 42. By linearly integrating the transfer chamber 11, the airbag chamber 12, and the pressure-holding chamber 4, the space required for the dispersed installation of the control components 5 is reduced. This makes the entire system more compact, thereby reducing the size and weight of the equipment and simplifying production and assembly. The simpler and clearer structure also makes later maintenance and upkeep easier.

[0042] Preferably, the control component 5 is a solenoid valve. The solenoid valve achieves switching control through electromagnetic principles, can quickly respond to control signals, and accurately control parameters such as gas flow and pressure to ensure the stability of the production process.

[0043] Optionally, the vent port 31 is also connected to a silencer, which includes a silencer housing and silencer cotton. A silencer cavity is provided inside the silencer housing, and the vent port 31 communicates with the silencer cavity. A silencer outlet is provided on the silencer housing, and the silencer cotton is placed inside the silencer cavity. Gas flows into the silencer cavity through the vent port 31. The silencer cotton absorbs the airflow within the silencer cavity, reducing standing waves and resonance, thus lowering the venting noise. The gas finally flows out through the silencer outlet, effectively absorbing and reflecting the sound waves generated during inflation and deflation, thereby reducing the noise level.

[0044] In this embodiment 1, the air inlet channel 2 and the air outlet channel 3 are spaced apart and arranged with alternating gas flow inside them. This spacing ensures that the gases do not interfere with each other during flow, thereby improving gas flow efficiency and reducing resistance and pressure loss within the channels. This allows the gas to enter and exit the cavity assembly more smoothly. Specifically, when the air pump starts inflating the air inlet port 21, the three airbag control components 52 respectively control the three airbag ports 12 to connect with the three airbag cavities 121, ensuring that the air inlet channel 2 is connected to the three airbag ports 12, while simultaneously connecting the three airbag ports 12 to the air outlet channel 3. The passage 3 remains closed; the transfer chamber control component 51 controls the connection between the transfer chamber 11 and the transfer valve interface 111, ensuring that the air intake channel 2 is connected to the transfer chamber 11, while keeping the transfer chamber 11 and the venting channel 3 closed; the pressure holding chamber control component 53 controls the gas flow direction in the pressure holding chamber to flow from the first interface 41 to the second interface 42, the air intake interface 21 takes in the gas, and the gas flows along the air intake channel 2 through the transfer valve interface 111 and the first interface 41 in sequence before flowing out from the second interface 42. At the same time, the three airbag chambers 12 will also inflate the airbags, achieving the effect of inflating the lumbar support airbag and the airbag, causing the sofa cushion to expand. When deflation is required, the airbag chamber control component 52 controls the three airbag chambers 12 to connect with the deflation channel 3, while keeping the three airbag chambers 12 closed to the air intake channel 2. The transfer chamber control component 51 controls the transfer chamber 11 to connect with the deflation channel 3, while keeping the transfer chamber 11 closed to the air intake channel 2. The pressure-holding chamber control component 53 controls the gas flow direction in the pressure-holding chamber to flow from the second interface 42 to the first interface 41. The gas in the lumbar support airbag flows from the first interface 41 through the second interface 42 and then enters the deflation channel 3 from the pressure-holding interface, finally exiting from the deflation interface 31. The gas in the sofa cushion airbag flows directly into the deflation channel 3 from the airbag interface 121 and finally exits from the deflation interface 31. The exited gas is then silenced by a muffler before being discharged. By adjusting the opening of the control component 5, the pressure and flow of the gas are controlled, which helps to avoid chaotic gas flow inside the chamber, thereby improving the control accuracy and stability of the gas. This allows the gas to flow more flexibly during the venting process, which helps to optimize gas management. In scenarios where precise control of gas emission is required, the venting rate can be precisely controlled by adjusting the opening degree of the second interface 42 and the airbag interface 121.

[0045] This utility model also relates to a solenoid valve control assembly, employing a pressure-holding gas control chamber assembly, including an assembly housing 6, a first flow guide 7, and a second flow guide 8. The control component 5 is assembled within the assembly housing 6. The first flow guide 7 is connected to the assembly housing 6, and the second flow guide 8 is connected to the first flow guide 7. The pressure-holding chamber 4 is disposed within the second flow guide 8. The airbag interface 121, the transfer valve interface 111, the air inlet interface 21, the first interface 41, and the second interface 42 all extend through the second flow guide 8. This integrated design achieves structural compactness. It not only reduces the floor space but also improves the integration of the components, making the entire system simpler and more efficient. The pressure-holding gas control chamber assembly optimizes the gas flow path, helping to reduce energy consumption and cost. Precise control of the control component 5 can reduce unnecessary energy loss and waste.

[0046] Preferably, the first flow guide 7 and the second flow guide 8 are detachably connected, and / or, the first flow guide 7 is detachably connected to the assembly housing 6. Optionally, the connection between the first flow guide 7 and the second flow guide 8 includes, but is not limited to, snap-fit, adhesive, screw-fit, or fixed connection. In this embodiment 1, the first flow guide 7 is provided with a first connecting post 71, the second flow guide 8 is provided with a second connecting post 81, and a fastener is provided between the first connecting post 71 and the second connecting post 81. The fastener can fix the first flow guide 7 and the second flow guide 8, so that the components between the first flow guide 7, the second flow guide 8, and the assembly housing 6 can be easily disassembled and reinstalled. This greatly simplifies the maintenance and replacement process, reduces maintenance costs, and improves work efficiency. At the same time, it ensures a stable connection between the first flow guide 7 and the second flow guide 8, which not only helps prevent gas leakage but also ensures the stable operation of the components in high-pressure or high-flow-rate gas environments.

[0047] Optionally, in this embodiment 1, the first flow guide 7 is provided with a snap-fit ​​protrusion 72, and the assembly housing 6 is provided with a snap-fit ​​groove 61. The snap-fit ​​protrusion 72 and the snap-fit ​​groove 61 are fixedly connected. This arrangement makes the disassembly process simpler and improves maintenance efficiency. At the same time, the tight fit between the snap-fit ​​protrusion 72 and the snap-fit ​​groove 61 helps prevent gas leakage and component loosening. In other embodiments, the first flow guide 7 and the assembly housing 6 are connected by, but not limited to, welding, fixed connection, or bonding.
