Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to an airbag massage control box and an airbag massage device. Background Technology

[0002] In existing technologies, the control box of airbag massage devices has several problems. First, its large size not only increases the overall space occupied by the device, making it extremely inconvenient to place in a limited space, but also imposes a heavy burden when carrying and moving the device. Second, the air tank capacity is relatively small, which means that it may not be able to provide sufficient and stable air pressure during massage operations, affecting the quality and effect of the massage and failing to meet the user's need for long-term massage.

[0003] In practical use cases, such as at home, users may want to place the massage device in different locations like the living room, bedroom, or study. However, the control box is quite large, making it difficult to find a suitable place to put it, and it is prone to collisions with surrounding furniture or other items or taking up too much space. In commercial venues, such as massage parlors or gyms, the centralized placement of multiple massage devices with a large control box makes the already limited business space feel even narrower, reducing space utilization. Furthermore, the small capacity of the air tank results in insufficient air pressure during the massage, failing to achieve the ideal massage intensity and effect. Users need to frequently refill the air tank, increasing the complexity and inconvenience of use. Therefore, existing users have opted for larger capacity air tanks to increase massage air pressure, resulting in the entire airbag massage device occupying a larger space and significantly reducing its ease of use. Utility Model Content

[0004] The main purpose of this invention is to propose an airbag massage control box and an airbag massage device, which aims to reduce the size while improving ease of use.

[0005] To achieve the above objectives, this utility model proposes an airbag massage control box, which includes a shell, an air tank, an integrated air valve, an air pump, and a control circuit board. The shell has an inner cavity, and the air tank, the integrated air valve, the air pump, and the control circuit board are all installed in the inner cavity. The integrated air valve and the air pump are respectively connected to the air tank, and both the integrated air valve and the air pump are electrically connected to the control circuit board. One end of the integrated air valve forms multiple air inlet pipes with the air tank, and the other end of the integrated air valve is used to connect with multiple airbags to form multiple air outlet pipes.

[0006] In one embodiment, the integrated air valve includes at least four first solenoid valves, one end of each of the four first solenoid valves being connected in parallel to the air storage tank to form a plurality of air inlet pipes;

[0007] The other end of each of the four first solenoid valves is used to communicate with the corresponding airbags to form multiple air outlet pipes.

[0008] In one embodiment, the integrated gas valve further includes at least two second solenoid valves, each of which is adjacent to each of the first solenoid valves. One end of each of the two second solenoid valves is connected in parallel to the gas storage tank, and the other end of each of the two second solenoid valves is used to communicate with the corresponding air bladder. One of the second solenoid valves is energized and opened, while the other second solenoid valve is de-energized and closed, so that a pressure-holding pipeline is formed between the de-energized second solenoid valve and the gas storage tank.

[0009] In one embodiment, the outer wall of the integrated air valve is fitted with a first sponge pad.

[0010] In one embodiment, the first sponge pad is disposed around the circumferential outer wall of the integrated air valve.

[0011] In one embodiment, the control circuit board is located above the integrated air valve; the airbag massage control box also includes sound-absorbing cotton, which is located between the control circuit board and the integrated air valve.

[0012] In one embodiment, the outer wall of the air pump is fitted with a rubber sleeve, and the rubber sleeve is arranged around the peripheral wall of the air pump.

[0013] In one embodiment, a second sponge pad is provided on the top of the gas storage tank, and the second sponge pad is arranged around the circumferential outer wall of the gas storage tank.

[0014] In one embodiment, the housing includes:

[0015] upper shell; and

[0016] The lower shell is detachably connected to the upper shell and encloses the inner cavity. The inner wall of the lower shell is provided with a mounting partition, which divides the inner wall of the lower shell to form at least three mounting positions. The gas storage tank, the integrated gas valve, and the gas pump are respectively installed in one of the mounting positions, and the control circuit board and the integrated gas valve are located in the same mounting position.

[0017] This utility model also proposes an airbag massage device, the airbag massage device comprising:

[0018] Multiple airbags; and

[0019] As described above, the airbag massage control box is connected to a plurality of airbags so that the airbag massage control box controls the operation of the plurality of airbags.

[0020] The airbag massage control box of this utility model includes a shell, an air tank, an integrated air valve, an air pump, and a control circuit board. The shell has an inner cavity, in which the air tank, integrated air valve, air pump, and control circuit board are all installed. The integrated air valve and air pump are respectively connected to the air tank, and both are electrically connected to the control circuit board. One end of the integrated air valve forms multiple air inlet pipes with the air tank, and the other end is used to connect with multiple airbags to form multiple air outlet pipes. In this way, the three-dimensional integrated layout allows all components to share a sealed cavity, effectively reducing the overall size of the control box and enabling the device to be deployed normally in a confined space.

[0031] In existing technologies, the control box of airbag massage devices is too large, resulting in low space utilization, and insufficient air tank capacity leads to unstable air pressure. In home environments, users often face difficulties in placing the device, especially when used in multiple rooms, requiring repeated adjustments. In commercial venues, the problem of space congestion is even more pronounced when multiple devices are placed together. Insufficient air tank capacity causes air pressure fluctuations during massage, requiring users to frequently replenish the air, affecting the user experience.

[0032] To address the aforementioned issues and the conflict between control box volume and air pressure stability, the following analysis was conducted: First, the shortcomings of the existing dispersed layout were analyzed, revealing that independent component installation leads to low space utilization. Second, there is a direct correlation between air tank capacity and air pressure stability; simply increasing the air tank volume would further exacerbate the space constraint. Therefore, a three-dimensional spatial reconstruction of the air path system and control system was proposed, achieving a compact design through optimized internal component layout. Based on this, a linkage mechanism between the air tank and the air pump was established to achieve dynamic air pressure compensation within a limited volume.

[0033] Therefore, please refer to Figures 1 to 3 This application discloses an airbag massage control box, including a housing 10, an air tank 20, an integrated air valve 30, an air pump 40, and a control circuit board 50. The housing 10 has an inner cavity, in which the air tank 20, integrated air valve 30, air pump 40, and control circuit board 50 are all installed. The integrated air valve 30 and air pump 40 are respectively connected to the air tank 20, and both the integrated air valve 30 and air pump 40 are electrically connected to the control circuit board 50. One end of the integrated air valve 30 forms multiple air inlet pipes with the air tank 20, and the other end is used to connect with multiple airbags to form multiple air outlet pipes.

[0034] In this embodiment, the outer shell 10 refers to the enclosed structure that carries the internal components. The gas storage tank 20 refers to the container for storing compressed gas, which can be implemented using an aluminum alloy cylindrical structure, and its capacity can be designed to match the output power of the air pump 40. The integrated air valve 30 refers to a multi-channel air path control device. The air pump 40 refers to a gas pressure supply device, which can be implemented using a diaphragm air pump 40, with its air inlet connected to the external environment and its air outlet connected to the gas storage tank 20. The control circuit board 50 refers to the air path control unit, which can be implemented using a PCB board with a microprocessor, and controls the opening and closing sequence of the solenoid valve through a preset program. The air inlet pipe refers to the connection channel between the gas storage tank 20 and the integrated air valve 30, which can be implemented using a silicone hose with a quick-connect fitting. The air outlet pipe refers to the connection channel between the integrated air valve 30 and the airbag, which can be implemented using a PU tube with a one-way valve.

[0035] Specifically, the air tank 20, as the core air source, is connected to the integrated air valve 30 through multiple air inlet pipes, forming a parallel air circuit structure. When the control circuit board 50 issues a command, the corresponding solenoid valve in the integrated air valve 30 opens, and the compressed gas in the air tank 20 enters the solenoid valve cavity through the air inlet pipe, and is then delivered to the target airbag through the air outlet pipe. The air pump 40 monitors the pressure value in the air tank 20 in real time. When the pressure is detected to be lower than the set threshold, it automatically starts to replenish air to maintain a stable air source pressure. The control circuit board 50 controls the opening sequence and duration of each solenoid valve through programming to achieve rhythmic control of airbag inflation and deflation. The functional components are arranged in a three-dimensional stacked layout within the housing. The air tank 20 is arranged horizontally at the bottom of the housing, the integrated air valve 30 and the air pump 40 are arranged side by side above the air tank 20, and the control circuit board 50 is installed in the top space of the housing.

[0036] Compared to existing technologies, traditional control boxes employ a split structure, resulting in low space utilization. This solution, however, utilizes a three-dimensional integrated layout, allowing all components to share a single sealed cavity. In existing technologies, the single-pipe connection between the air tank 20 and the air valve can easily lead to pressure fluctuations. This solution establishes redundant air paths through multiple air inlet pipes, ensuring balanced pressure distribution. In conventional solutions, the air pump 40 serves only as an independent air replenishment unit. This solution achieves intelligent linkage between the air pump 40 and the air tank 20 through a pressure sensing feedback mechanism, maintaining constant pressure within a limited volume.

[0037] The above technical solutions effectively reduce the overall size of the control box, allowing the device to be deployed normally even in confined spaces. The multi-airflow design ensures independent air supply to multiple airbags, preventing air pressure fluctuations from affecting the consistency of massage intensity. The intelligent linkage mechanism between the air pump 40 and the air tank 20 extends continuous working time and reduces the frequency of user intervention. The compact layout design enhances the product's portability and environmental adaptability while maintaining functional integrity.

[0038] Please see Figures 1 to 3 This application further proposes that the integrated air valve 30 includes at least four first solenoid valves 31, one end of the four first solenoid valves 31 is connected in parallel to the air tank 20 to form multiple air inlet pipes, and the other end of the four first solenoid valves 31 is used to communicate with the corresponding airbag to form multiple air outlet pipes.

[0039] In this embodiment, the first solenoid valve 31 refers to a valve element that can control the gas flow through an electrical signal. Specifically, it can be achieved by using an electromagnetic coil to drive the valve core to move, thereby enabling independent control of the air supply to the airbag. Parallel connection means that the inlet ends of multiple first solenoid valves 31 are connected to the same gas source interface of the gas storage tank 20. This can be achieved using branch pipelines or an integrated gas path block structure, thereby reducing the number of pipelines at the outlet of the gas storage tank 20 and compressing space occupation. The inlet pipeline refers to the gas passage from the gas storage tank 20 to the inlet end of the first solenoid valve 31. Specifically, it can be a straight short pipe or an internal gas passage design to reduce space waste caused by pipeline bends. The outlet pipeline refers to the gas passage extending from the outlet end of the first solenoid valve 31 to the corresponding airbag. Specifically, it can be a one-to-one connected straight-through pipeline layout to avoid airflow interference between airbags.

[0040] Specifically, by integrating the air inlet ends of at least four first solenoid valves 31 in parallel with the air tank 20, a shared air input path is formed, allowing each solenoid valve to share the air pressure resources of the air tank 20. When the control circuit board 50 sends an electrical signal to a specific solenoid valve, the corresponding air inlet and outlet pipes are connected, and gas is directly delivered from the air tank 20 to the target airbag via that solenoid valve. Because the four solenoid valves are arranged in a compact parallel layout, multiple air valves and their connecting pipes that would otherwise require independent installation are integrated into a single module, significantly reducing the space occupied within the control box. Simultaneously, each solenoid valve independently controls the outlet path of its corresponding airbag, ensuring that even with a limited capacity in the air tank 20, time-sharing control can prevent a sudden drop in air pressure caused by simultaneous inflation of multiple airbags, thus maintaining air pressure stability.

[0041] Compared to existing technologies, traditional solutions require each airbag to be equipped with an independent air valve and connected to the air tank 20, resulting in a large number of pipelines with a loose layout and a large space occupation. This solution, however, integrates the air source inputs of the four air valves into a single connection point through parallel connection, reducing the number of pipeline branches at the outlet of the air tank 20 and making the internal air circuit structure more compact. Furthermore, the dispersed arrangement of multiple air valves in existing technologies easily leads to pipeline bends and intersections, while this solution uses symmetrically arranged solenoid valve modules to make the air outlet pipelines radially connect directly to the airbags, further optimizing space utilization.

[0042] Because the four solenoid valves can independently control the inflation and deflation sequence of the airbags, even if the capacity of the air tank 20 is not increased, the time-sharing air supply can still avoid insufficient air pressure caused by multiple airbags working simultaneously. This ensures that each airbag receives a continuous and stable air pressure supply during the inflation phase, thereby improving the uniformity of the massage intensity. For example, in a back massage scenario, the four airbags can inflate alternately, ensuring that each airbag receives full air supply from the air tank 20 during inflation, avoiding air pressure fluctuations caused by parallel airflow diversion.

[0043] Please see Figures 1 to 3 This application further proposes that the integrated air valve 30 includes at least two second solenoid valves 32, each of which is adjacent to each first solenoid valve 31. One end of each of the two second solenoid valves 32 is connected in parallel to the air tank 20, and the other end of each of the two second solenoid valves 32 is used to communicate with the corresponding airbag. One of the second solenoid valves 32 is energized and opened, while the other second solenoid valve 32 is de-energized and closed, so that a pressure-holding pipeline is formed between the de-energized second solenoid valve 32 and the air tank 20.

[0044] In this embodiment, the second solenoid valve 32 is an actuator that controls the flow of gas via electromagnetic control. Specifically, it can be implemented as a two-position, two-normally closed solenoid valve, which, in its de-energized state, can close the gas path to form a pressure-maintaining circuit. The pressure-maintaining pipeline refers to the closed gas path formed between the de-energized second solenoid valve 32 and the gas storage tank 20. Specifically, this can be achieved by connecting the internal channel of the second solenoid valve 32 to the outlet of the gas storage tank 20, used to maintain stable gas pressure within the pipeline. Adjacent arrangement means that the second solenoid valve 32 and the first solenoid valve 31 are physically adjacent within the valve assembly. Specifically, this can be achieved by integrating them into the same valve block to optimize the compactness of the gas path layout.

[0045] Specifically, in the integrated gas valve 30 structure where the second solenoid valve 32 and the first solenoid valve 31 are arranged adjacently, the two second solenoid valves 32 are connected in parallel with the gas storage tank 20, forming a gas path branch independent of the control of the first solenoid valve 31. When one of the second solenoid valves 32 is energized and opened, the gas in the gas storage tank 20 flows through the valve to the corresponding air bladder; the other second solenoid valve 32 is in the de-energized and closed state, and its internal channel forms a sealed space with the outlet of the gas storage tank 20, effectively trapping the gas pressure in the pipeline. By switching the on and off states of the two valves, the working position of the pressure-holding circuit can be dynamically selected without changing the capacity of the gas storage tank 20. This design eliminates the need for the air pump 40 to frequently start to replenish the gas pressure, while maintaining the pressure stability of the gas path system.

[0046] Compared to existing technologies, traditional solutions require increasing the volume of the gas storage tank (20) or adding an independent pressure-maintaining device to maintain stable gas pressure. This solution, however, uses the coordinated control of a solenoid valve to form a pressure-maintaining circuit, achieving the same gas pressure maintenance function with the same gas storage tank (20) capacity. Existing technologies require additional one-way valves or pressure sensors for linkage control, while this solution achieves this simply through the state switching of the solenoid valve, significantly simplifying the gas circuit system structure.

[0047] Through the above technical solution, this application achieves stable air pressure control within a limited space, solving the problem of frequent pressure replenishment required for small-capacity air tank 20 due to insufficient air pressure. The adjacent arrangement of the second solenoid valve 32 and the first solenoid valve 31 reduces pipeline length and avoids increasing equipment size due to the addition of pressure-maintaining devices. The coordinated on / off control of the two valves can effectively reduce the operating frequency of the air pump 40, extend the service life of the equipment, and ensure the continuity of air pressure output during the massage process.

[0048] Please see Figures 1 to 3 This application further proposes to cover the outer wall of the integrated air valve 30 with a first sponge pad 60.

[0049] In this embodiment, the first sponge pad 60 refers to an annular pad made of porous elastic material, specifically polyurethane sponge or rubber sponge, whose porous structure can absorb mechanical vibration energy through deformation. "Sleeving" refers to wrapping the sponge pad around the circumferential outer surface of the valve, which can be achieved by adhesive or snap-fit ​​fixing, so that the sponge pad forms a continuous contact surface with the outer wall of the valve.

[0050] Specifically, when the integrated air valve 30 is operating, the vibration generated by the opening and closing of the solenoid valve is transmitted to the sponge pad through the valve body housing 10. The sponge pad converts the vibration energy into heat energy through the compression deformation of the material's internal pores, thereby reducing the amplitude of vibration transmission to the housing 10. At the same time, the sponge pad covers the entire surface of the air valve's outer wall, forming a flexible isolation layer between it and adjacent components, preventing rigid collisions between the air valve and the inner wall of the housing 10 or components such as the air pump 40. This eliminates abnormal noises caused by contact friction and reduces the risk of wear on the outer wall of the air valve due to long-term vibration.

[0051] Through the above technical solution, this application realizes the absorption of vibration energy during the operation of the integrated air valve 30, reduces the overall noise level of the equipment, avoids direct friction contact between the outer wall of the air valve and other components, extends the service life of the air valve, and improves the stability and quietness of the control box.

[0052] Please see Figures 1 to 3 This application further proposes that a first sponge pad 60 is arranged around the circumferential outer wall of the integrated air valve 30.

[0053] In this embodiment, the first sponge pad 60 refers to a flexible sound-absorbing material with a porous structure, specifically polyurethane foam. Its internal pores can absorb mechanical vibration energy and attenuate sound wave transmission through deformation. The circumferential outer wall refers to the cylindrical side surface of the integrated air valve 30 extending along its axial direction. Specifically, it can be achieved by measuring the outer diameter of the air valve and cutting a sponge ring of corresponding size. The surrounding layout allows the sponge pad to form a 360-degree contact surface with the outer wall of the air valve.

[0054] Specifically, when the integrated air valve 30 vibrates radially under the opening and closing of the solenoid valve and the impact of airflow, the vibration energy is transferred to the porous structure of the first sponge pad 60, where it is converted into heat energy through material deformation and dissipated. The circumferential wrapping structure of the sponge pad covers the entire vibration transmission path of the outer wall of the air valve, blocking the channel for vibration waves to radiate outward through the inner wall of the outer shell 10. When the equipment is subjected to external impact or movement, the elastic properties of the sponge pad buffer the possible rigid contact between the air valve and the outer shell 10, avoiding direct collision between metal parts.

[0055] Through the above technical solution, this application can effectively suppress the propagation of mechanical noise generated during the operation of the integrated air valve 30 to the outside of the control box, reducing the sound pressure level during equipment operation. Simultaneously, it avoids hard collisions between the air valve and the inner wall of the housing 10 during vibration or movement, reducing the risk of metal fatigue and structural deformation, and extending the service life of the air valve assembly. The surrounding layout of the sponge pad eliminates the need for additional fixing structures, achieving multi-dimensional protection while maintaining the compactness of the control box.

[0056] Please see Figures 1 to 3 This application further proposes that the control circuit board 50 is located above the integrated air valve 30, and that a sound-absorbing cotton 70 is added between the control circuit board 50 and the integrated air valve 30.

[0057] In this embodiment, the control circuit board 50 being located above the integrated air valve 30 means that the two are arranged in layers vertically. Specifically, a mounting bracket or snap-fit ​​structure can be used to fix the circuit board in the area directly above the integrated air valve 30, thereby avoiding horizontal expansion of the width or length of the outer casing 10 and maintaining a compact distribution of internal components. The sound-absorbing cotton 70 refers to a flexible material layer with sound-absorbing and buffering properties. Specifically, it can be made of polyester fiber cotton or silicone sponge cut into sheets and filled in the gap between the bottom surface of the control circuit board 50 and the top surface of the integrated air valve 30. This physically isolates and absorbs the superposition and propagation of low-frequency noise generated by the mechanical vibration of the solenoid valve and high-frequency current noise from the circuit board.

[0058] Please see Figures 1 to 3 This application further proposes that the outer wall of the air pump 40 is fitted with a rubber sleeve 80, and the rubber sleeve 80 is arranged around the peripheral wall of the air pump 40.

[0059] In this embodiment, the rubber sleeve 80 refers to an elastic material layer wrapped around the outside of the air pump 40, which can be made of silicone or synthetic rubber. It absorbs vibration energy and blocks the vibration transmission path through its deformation capacity. The surrounding wall of the air pump 40 means that the rubber sleeve 80 covers the entire outer surface of the air pump 40 in a continuous annular structure. This can be achieved by integral molding or modular splicing, ensuring that the vibration energy of the air pump 40 during operation is uniformly absorbed without local leakage.

[0060] Specifically, when the air pump 40 operates and generates mechanical vibration, the rubber sleeve 80 converts the vibration energy into heat energy and dissipates it through elastic deformation, preventing the vibration from being transmitted outward through the outer casing 10 and generating noise. Since the rubber sleeve 80 covers the entire circumferential outer wall of the air pump 40, vibration energy cannot be directly transmitted from the contact point between the air pump 40 and the outer casing 10, thus eliminating noise amplification caused by localized rigid connections. Simultaneously, the rubber sleeve 80 forms a flexible isolation layer between the air pump 40 and the outer casing 10, reducing direct contact friction between the two and preventing structural wear or loosening of connections caused by long-term vibration.

[0061] Please see Figures 1 to 3 This application further proposes to provide a second sponge pad 90 around the circumferential outer wall of the gas storage tank 20 at the top.

[0062] In this embodiment, the second sponge pad 90 refers to a shock-absorbing component made of porous elastic material, specifically polyurethane sponge with a density of 25 kg / m³ to 35 kg / m³ and a thickness of, for example, 3 mm to 8 mm, surrounding and wrapping the junction area between the top and sidewall of the gas storage tank 20. This structure absorbs the mechanical vibration energy generated by gas pressure fluctuations in the gas storage tank 20 through elastic deformation, blocking the transmission path of vibration to surrounding components. The circumferential outer wall surrounding the gas storage tank 20 means that the sponge pad extends downwards along the top edge of the gas storage tank 20 to cover its outer wall surface. Specifically, this can be achieved by continuously attaching annular strips of sponge to the outer wall of the gas storage tank 20, with a coverage width, for example, 20% to 30% of the height of the outer wall of the gas storage tank 20. This arrangement allows the sponge pad to simultaneously buffer vertical vibrations at the top of the gas storage tank 20 and horizontal vibrations at the sidewall, preventing rigid collisions between the gas storage tank 20 and the inner wall of the outer casing 10.

[0063] Specifically, when changes in internal air pressure cause vibration in the gas storage tank 20, the second sponge pad 90 dissipates the vibration energy as heat through compression deformation within its internal pores, reducing the vibration amplitude. The wraparound design ensures the sponge pad evenly covers the vibration transmission area of ​​the top and side walls of the gas storage tank 20, reducing material fatigue caused by localized stress concentration. Simultaneously, the elastic support of the sponge pad maintains the gas storage tank 20 in a stable position within the limited installation space, preventing loosening or leakage at pipe connections due to vibration-induced displacement.

[0064] Please see Figures 1 to 3 This application further proposes that the outer shell 10 includes an upper shell 11 and a lower shell 12. The lower shell 12 is detachably connected to the upper shell 11 and encloses it to form an inner cavity. The inner wall of the lower shell 12 is provided with a mounting partition 13. The mounting partition 13 and the inner wall of the lower shell 12 are divided to form at least three mounting positions. The air tank 20, the integrated air valve 30, and the air pump 40 are respectively installed in one mounting position, and the control circuit board 50 and the integrated air valve 30 are located in the same mounting position.

[0065] In this embodiment, the detachable connection between the upper shell 11 and the lower shell 12 means that they are fixed together by snaps or screws to form a separable structure. Specifically, snap-fit ​​connectors or threaded connectors can be used to facilitate the opening and closing of the outer shell 10. The mounting partition 13 is a plate-like structure set on the inner wall of the lower shell 12. Specifically, it can be integrally formed with the inner wall of the lower shell 12 by injection molding process, and is used to divide the inner cavity space of the lower shell 12. The mounting position is an independent area formed by the mounting partition 13 and the inner wall of the lower shell 12. Specifically, it can be divided into spaces by asymmetrical geometry, and is used to fix the gas tank 20, the integrated gas valve 30, and the gas pump 40.

[0066] Specifically, through the detachable upper shell 11 and lower shell 12 structure, the outer shell 10 can be quickly disassembled for the installation or maintenance of internal components. The mounting partition 13 extends along the inner wall of the lower shell 12, dividing the inner cavity into three independent mounting positions, allowing the gas tank 20, integrated air valve 30, and air pump 40 to be fixed in different mounting positions, avoiding physical interference between components. The control circuit board 50 and integrated air valve 30 are located in the same mounting position, utilizing their electrical connection characteristics to shorten wire length and reduce the space occupied by wiring. Thus, the spatial division and component positioning of the mounting partition 13 work together to achieve a compact arrangement of components within the limited inner cavity space, providing a spatial basis for the capacity expansion of the gas tank 20.

[0067] In some specific embodiments, the mounting partition 13 can be a vertical or inclined partition. For example, an L-shaped partition can be used to divide the inner cavity of the lower shell 12 into three asymmetrical mounting positions, wherein the air tank 20 is installed in the largest mounting position, the air pump 40 is installed in the mounting position with a shock-absorbing structure, and the integrated air valve 30 and control circuit board 50 are installed in the mounting position near the side wall of the outer shell 10.

[0068] Through the above technical solution, this application solves the problem of excessive volume caused by unreasonable internal component layout of the airbag massage control box. By dividing the space with the partition 13, the air tank 20, air pump 40 and integrated air valve 30 are arranged in a compact manner. The capacity of the air tank 20 is increased while keeping the volume of the outer shell 10 unchanged. At the same time, the co-installation layout of the control circuit board 50 and the integrated air valve 30 reduces circuit redundancy and further optimizes space utilization.

[0069] Please see Figure 2 This application further proposes an airbag massage device, including multiple airbags and an airbag massage control box, wherein the airbag massage control box is connected to the multiple airbags to control their operation.

[0070] In this embodiment, the airbag massage control box refers to a modular device comprising a housing 10, an air tank 20, an integrated air valve 30, an air pump 40, and a control circuit board 50. Specifically, a split housing 10 and mounting partition 13 can be used to achieve a compact layout of the internal components. The partition divides the space into multiple mounting positions to fix the air tank 20, air pump 40, and control circuit board 50, thereby reducing space occupation. The multiple airbags refer to independently controlled inflation units. Specifically, the integrated air valve 30 can be used to connect multiple pipelines to achieve independent inflation and deflation of each airbag. The pressure-maintaining pipeline is controlled by a solenoid valve to maintain stable air pressure, thereby avoiding frequent starting of the air pump 40.

[0071] Specifically, the air tank 20 is filled with compressed gas by the air pump 40, and multiple solenoid valves of the integrated air valve 30 are connected to different air bags to form independent air paths. The control circuit board 50 controls the opening and closing of the solenoid valves according to instructions to realize the inflation, pressure holding, or deflation of the air bags. The outer shell 10 adopts a detachable upper and lower shell structure 12, and the internal partition separates the air tank 20, air pump 40, and integrated air valve 30 into independent installation areas. The control circuit board 50 is arranged in the same area as the air valve to reduce electromagnetic interference. The rubber sleeve 80 on the outer wall of the air pump 40 and the sponge pad on the outer wall of the air valve are used to suppress vibration noise, and the sponge pad on the top of the air tank 20 further reduces the airflow impact noise.

[0072] Compared with existing technologies, the existing control box suffers from frequent air pressure fluctuations due to the small capacity of the air tank 20, and its large overall size makes it difficult to fit in confined spaces. This solution improves air storage efficiency by having the air tank 20 and air pump 40 work together, and the multi-pipe design of the integrated air valve 30 enables independent control of the airbag. The split-type outer shell 10 and partition layout compress the space volume, maintaining stable air pressure without increasing the size of the air tank 20, while also reducing the overall space occupied by the equipment.

[0073] Through the above technical solutions, the control box of the airbag massage device in home or commercial settings is reduced in size for flexible placement, the optimized capacity of the air tank 20 ensures a stable massage air pressure and reduces the number of inflations, the independent control of multiple airbags allows for precise adjustment of the massage intensity of different parts, and the pressure-maintaining pipeline avoids frequent start-stop of the air pump 40, reducing noise interference and extending the device's lifespan.

[0074] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
