[0033] This utility model proposes an airbag massage control box.

[0034] Please see Figures 1 to 3 In one embodiment of this utility model, the airbag massage control box includes a housing 10, an air pump 20, a first three-way air valve 30, a second three-way air valve 40, and a control board 50. The housing 10 has an inner cavity; the air pump 20 is installed in the inner cavity; the first three-way air valve 30 is installed in the inner cavity and communicates with the air pump 20; the second three-way air valve 40 is installed in the inner cavity and communicates with the first three-way air valve 30; and the second three-way air valve 40 is used to connect the first airbag 1 and the second airbag 2; the control board 50 is installed in the inner cavity and is electrically connected to the air pump 20, the first three-way air valve 30, and the second three-way air valve 40.

[0035] The outer casing 10 is the basic structure of the entire airbag massage control box, and its internal cavity provides space for the installation and housing of other components. The outer casing 10 not only protects the internal components but also provides structural support for the entire control box, ensuring the stability of each component during operation. The air pump 20 is the power source of the control box, responsible for generating airflow. Its main function is to compress and output air, providing the air pressure required for airbag inflation. The performance of the air pump 20 directly affects the inflation speed and air pressure stability of the airbags. The first three-way valve 30 is installed at the output end of the air pump 20, and its main function is to control the direction of airflow. By switching the state of the valve, the inflation and deflation functions of the airflow can be realized. The first three-way valve 30 typically has three ports, connected to the air pump 20, the second three-way valve 40, and the deflation channel, respectively. The second three-way valve 40 is connected downstream of the first three-way valve 30, and its main function is to further distribute the airflow. It has three ports, connected to the first three-way valve 30, the first airbag 1, and the second airbag 2, respectively. By controlling the state of the second three-way valve 40, independent inflation and deflation of the two airbags can be achieved. The control board 50 is the intelligent control center of the entire system, responsible for coordinating and controlling the operation of the air pump 20, the first three-way valve 30, and the second three-way valve 40. The control board 50 receives external commands or preset programs to control the operating status of each component, achieving precise control of airbag inflation and deflation.

[0036] When the control board 50 receives an inflation command, it first starts the air pump 20 to generate compressed air. The airflow enters the first three-way valve 30 through the output port of the air pump 20. Simultaneously, the control board 50 switches the first three-way valve 30 to the inflation state, allowing the airflow to flow through the first three-way valve 30 to the second three-way valve 40. Under the command of the control board 50, the second three-way valve 40 distributes the airflow to the first airbag 1 and the second airbag 2, thus inflating the airbags.

[0037] When the control board 50 receives a deflation command, it stops the air pump 20. Simultaneously, it switches the first three-way valve 30 to the deflation state, allowing the gas inside the airbag to escape through the deflation channel of the first three-way valve 30. The second three-way valve 40 maintains its corresponding state during the deflation process to ensure smooth airflow.

[0038] With precise control of the control panel 50, the first airbag 1 and the second airbag 2 can be independently inflated and deflated. For example, the control panel 50 can first control the second three-way valve 40 to inflate the first airbag 1, and then switch to inflate the second airbag 2, achieving an alternating inflation effect and enhancing the comfort and effectiveness of the massage.

[0039] This utility model's airbag massage control box employs a high-efficiency air pump 20, a precision three-way air valve, and a control board 50. The intelligent adjustment function of the control board 50 enables more precise air pressure regulation, improves the inflation and deflation speed of the airbag, and can meet users' needs for different massage intensities, thereby enhancing the massage effect and efficiency. Furthermore, the use of the three-way air valve effectively reduces noise during operation, improving the user experience.

[0040] In one embodiment, please refer to Figures 1 to 3 The first three-way valve 30 has a first outlet 30a, a second outlet 30b, and a third outlet 30c. The first outlet 30a and the second outlet 30b are located on the same side of the first three-way valve 30 and are interconnected. The third outlet 30c is located on the side of the first three-way valve 30 away from the first outlet 30a and is connected to the air pump 20. The second three-way valve 40 has a first air port 40a, a second air port 40b, and a third air port 40c. The first air port 40a and the second air port 40b are located on the same side of the second three-way valve 40 and are interconnected. The second air port 40b is used to communicate with the first airbag 1. The third air port 40c is located on the side of the second three-way valve 40 away from the first air port 40a and is used to communicate with the second airbag 2.

[0041] The first three-way vent valve 30, as a key component of the entire air circuit system, features a unique structural design. It has a first outlet 30a, a second outlet 30b, and a third outlet 30c. The first and second outlets 30a and 30b are located on the same side and are interconnected, facilitating smooth airflow switching between them under specific conditions. The third outlet 30c is located opposite the first outlet 30a and is connected to the air pump 20, responsible for introducing compressed air generated by the air pump 20 into the valve, providing the power source for inflating the airbag. The first three-way vent valve 30 uses electromagnetic control to switch the airflow direction, thereby enabling the inflation and deflation of the airbag.

[0042] The second three-way vent valve 40 also plays an important role in the air circuit system. It has a first air port 40a, a second air port 40b, and a third air port 40c. The first air port 40a and the second air port 40b are located on the same side and are interconnected. The second air port 40b is connected to the first airbag 1 and is used to inflate the first airbag 1. The third air port 40c is located on the other side and is connected to the second airbag 2, responsible for inflating the second airbag 2. The second three-way vent valve 40 works in conjunction with the first three-way vent valve 30, precisely distributing airflow through electromagnetic control to ensure that the two airbags can be independently inflated and deflated according to a preset program.

[0043] When the control panel 50 issues an inflation command, the air pump 20 starts, generating compressed air. The airflow first enters the third outlet 30c of the first three-way valve 30. Due to electromagnetic control, the airflow flows out from the first outlet 30a and enters the second three-way valve 40. In the second three-way valve 40, according to the command of the control panel 50, the airflow flows to the first airbag 1 through the first air port 40a and the second air port 40b, or to the second airbag 2 through the third air port 40c, completing the inflation process of the airbag.

[0044] During deflation, the control panel 50 controls the switching state of the first three-way valve 30 and the second three-way valve 40. The gas inside the airbag flows back to the second three-way valve 40 through the corresponding air port, then flows to the first three-way valve 30, and finally is discharged through the deflation channel of the first three-way valve 30, realizing the rapid deflation of the airbag.

[0045] When it is necessary to maintain the air pressure inside the airbag, the first three-way valve 30 and the second three-way valve 40, without being energized, use their internal mechanical structures to prevent the backflow of air, thereby maintaining the pressure of the airbag. The installation of the check valve 60 further ensures the stability of the air pressure and prevents the air pressure from dropping due to backflow.

[0046] This utility model's airbag massage control box uses a simple circuit to control the air valves. The coordinated operation of the dual air valves and the air pump 20 ensures precise air pressure control. Whether inflating, deflating, or maintaining pressure, the air pressure remains stable, thus providing a uniform massage effect. These technical effects collectively overcome the problems of cumbersome operation and unstable air pressure in existing technologies, bringing a new solution to the field of airbag massage devices.

[0047] In one embodiment, please refer to Figures 1 to 3 The airbag massage control box also includes a check valve 60, which is located between the air pump 20 and the third outlet 30c to prevent the gas from flowing back into the air pump 20 from the first three-way air valve 30.

[0048] The check valve 60 is a key component in the airbag massage control box, installed between the air pump 20 and the third outlet 30c of the first three-way valve 30. Its main function is to unidirectionally guide airflow, ensuring that gas can only flow from the air pump 20 to the first three-way valve 30 and cannot flow in the opposite direction. The check valve 60 achieves this function through an internal mechanical structure (such as a spring and valve core). When the air pressure generated by the air pump 20 exceeds a certain threshold, the valve core is pushed open, allowing gas to pass smoothly; when the air pump 20 stops working or the air pressure inside the airbag is higher than that on the air pump 20 side, the valve core closes under the action of spring force or air pressure difference, preventing gas from flowing back into the air pump 20.

[0049] During inflation, the air pump 20 starts and generates compressed air. The airflow enters the third outlet 30c of the first three-way valve 30 through the check valve 60. Due to the electromagnetic control, the first outlet 30a of the first three-way valve 30 opens, and the airflow flows to the second three-way valve 40. The second three-way valve 40 distributes the airflow to the corresponding airbags according to the instructions of the control panel 50. At this time, the check valve 60 is in the open state to ensure smooth airflow.

[0050] When deflation is required, the control panel 50 switches the first three-way valve 30 and the second three-way valve 40. Gas inside the airbag flows back to the second three-way valve 40 through the corresponding vent, and then back to the first three-way valve 30. At this time, due to the check valve 60, the gas does not flow back into the air pump 20, but is discharged through the deflation channel of the first three-way valve 30. The closure of the check valve 60 effectively prevents unnecessary load and wear on the air pump 20 during deflation.

[0051] In the pressure-holding state, the first three-way air valve 30 and the second three-way air valve 40 are not energized, using their internal structures to prevent airflow backflow. Simultaneously, the check valve 60 is also closed, further ensuring that the gas inside the airbag does not leak through the air pump 20. This dual protection mechanism allows the air pressure inside the airbag to remain stable, providing the user with a consistent massage effect.

[0052] In this embodiment, the airbag massage control box incorporates a check valve 60. The check valve 60 effectively prevents gas from flowing back into the air pump 20 during inflation and pressure holding, reducing wear and energy consumption of the air pump 20 and extending the device's lifespan. Simultaneously, the coordinated operation of the check valve 60 and the air valve ensures precise air pressure control, maintaining stable air pressure during inflation, deflation, and pressure holding, thereby providing a uniform and consistent massage effect.

[0053] In one embodiment, please refer to Figures 1 to 3 A sound-absorbing cotton 70 is installed at the first outlet 30a to reduce the noise during the venting process.

[0054] The sound-absorbing cotton 70 is installed at the first outlet 30a of the first three-way vent valve 30, mainly used to reduce noise during the venting process. The sound-absorbing cotton 70 is a porous material that can absorb and disperse sound waves generated during venting, thereby significantly reducing noise. Its working principle is that through its internal porous structure, sound waves are continuously reflected and attenuated during propagation, ultimately achieving a noise reduction effect.

[0055] When deflation is required, the control panel 50 switches the first three-way vent valve 30 to the deflation state. The gas inside the airbag flows back to the first three-way vent valve 30 through the second three-way vent valve 40, and then exits from the first outlet 30a. At this time, the airflow passes through the sound-absorbing cotton 70, which absorbs and disperses sound waves through its porous structure, significantly reducing the noise during deflation.

[0056] In this embodiment, the airbag massage control box provides sound-absorbing cotton 70 at the first outlet 30a. The porous structure of the sound-absorbing cotton 70 effectively absorbs and disperses the sound waves generated by the airflow during deflating.

[0057] In one embodiment, please refer to Figures 1 to 3 The outer wall of the air pump 20 is provided with a first sponge pad 80.

[0058] The first sponge pad 80 is installed on the outer wall of the air pump 20, mainly to absorb the vibration and noise generated during the operation of the air pump 20. The sponge pad is a soft and elastic material that can effectively buffer the mechanical vibration generated by the air pump 20 during operation, reducing the vibration transmitted to the housing 10 and other components. At the same time, the sponge pad also has a certain sound insulation effect, which can block the propagation path of noise, thereby reducing the overall noise level of the equipment.

[0059] The air pump 20 is the power source for the airbag massage control box, responsible for generating compressed air. Its working principle involves a motor driving a piston or impeller to compress air and output it to the air circuit system. During operation, the air pump 20 will generate some vibration and noise. If this vibration and noise are not controlled, it will directly affect the user experience and comfort.

[0060] During inflation, the air pump 20 starts and generates compressed air. At this time, vibration and noise from the air pump 20 are inevitable. The first sponge pad 80, through its soft material and elastic structure, absorbs the vibration of the air pump 20, reducing the transmission of vibration to the outer casing 10 and other components. Simultaneously, the sound insulation effect of the sponge pad blocks some of the noise transmission, making the inflation process quieter.

[0061] In this embodiment, the airbag massage control box incorporates a first sponge pad 80 on the outer wall of the air pump 20. This first sponge pad 80 absorbs the mechanical vibrations generated during the operation of the air pump 20, reducing the transmission of vibrations to the outer casing 10 and other components, thereby lowering the overall noise level of the device. Simultaneously, the sound insulation effect of the sponge pad further blocks the propagation path of noise.

[0062] In one embodiment, please refer to Figures 1 to 3 The first sponge pad 80 is arranged around the outer wall of the air pump 20.

[0063] The first sponge pad 80 is a soft and highly elastic foam material designed in a ring shape, tightly and evenly surrounding the outer wall of the air pump 20. This surrounding layout ensures that vibrations of the air pump 20 in all directions are effectively absorbed and cushioned.

[0064] The surrounding sponge pad layout of this embodiment can absorb the vibration generated by the air pump 20 during operation from all directions, reduce the vibration transmitted to the housing 10 and other components, thereby reducing the overall noise level of the device.

[0065] In one embodiment, please refer to Figures 1 to 3 The outer walls of the first three-way vent valve 30 and the second three-way vent valve 40 are both provided with a second sponge pad 90.

[0066] The second sponge pad 90 is a soft and highly elastic foam material designed in a wraparound layout, tightly and evenly wrapping around the outer walls of the first three-way air valve 30 and the second three-way air valve 40. This wraparound design ensures that vibrations of the valves in all directions are effectively absorbed and buffered. The porous structure inside the sponge pad dissipates vibration energy through the compression and expansion of air, thereby achieving a shock absorption effect. At the same time, the smooth surface of the sponge pad allows it to fit tightly against the outer wall of the air valve, ensuring that it will not shift or loosen during operation, providing continuous and stable shock absorption and noise reduction functions.

[0067] During operation, the movement of the electromagnetic coil and valve core inside the air valve will generate certain vibrations and noise. If these vibrations are not controlled, they will be transmitted to the outer casing 10 and other components, affecting the stability and noise level of the equipment.

[0068] In this embodiment, the airbag massage control box provides a second sponge pad 90 on the outer wall of the first three-way air valve 30 and the second three-way air valve 40. The surrounding sponge pad layout can absorb the vibration generated during the operation of the air valve in all directions, reducing the vibration transmitted to the outer shell 10 and other components, thereby reducing the overall noise level of the device.

[0069] In one embodiment, please refer to Figures 1 to 3 The bottom wall of the inner cavity is provided with two mounting baffles 11, which are arranged symmetrically and each mounting baffle 11 encloses one side wall of the inner cavity to form a mounting position; the first three-way vent valve 30 and the second three-way vent valve 40 are respectively installed in the two mounting positions.

[0070] The inner cavity is the space inside the airbag massage control box housing 10, used to accommodate and install various components. Mounting baffles 11 are two symmetrical structures on the bottom wall of the inner cavity, which enclose one side wall of the inner cavity to form a mounting position. The main function of these baffles is to provide a stable mounting base for the first three-way air valve 30 and the second three-way air valve 40, ensuring that the air valves do not shift or loosen during operation.

[0071] During installation, the first three-way air valve 30 and the second three-way air valve 40 are respectively placed in the mounting positions formed by the mounting baffle 11 and one side wall of the inner cavity. The mounting baffle 11, through its structural design, ensures that the air valves are stable in the mounting positions, preventing shaking or displacement during equipment operation or movement.

[0072] During equipment operation, the mounting baffle 11 provides stable support for the air valve, ensuring that the air valve can accurately execute electromagnetic control commands. During inflation, deflation, and pressure holding, the air valve controls the airflow direction through the movement of its internal electromagnetic coil and valve core. The stability of the mounting baffle 11 ensures the operating accuracy of the air valve and reduces airflow control errors caused by vibration or displacement. During maintenance, the design of the mounting baffle 11 makes the disassembly and installation of the air valve more convenient.

[0073] In this embodiment, the airbag massage control box achieves stable installation of the first three-way air valve 30 and the second three-way air valve 40 by setting symmetrical mounting baffles 11 on the bottom wall of the inner cavity and using these baffles to form mounting positions with one side wall of the inner cavity. This design ensures that the air valves will not shift or loosen during operation, thereby improving the stability and reliability of the air circuit system.

[0074] This utility model also proposes a massage device; please refer to [link / reference]. Figure 3 The massage device includes a first airbag 1, a second airbag 2, and an airbag massage control box; the second airbag 2 is spaced apart from the first airbag 1; the second three-way air valve 40 of the airbag massage control box is connected to the first airbag 1 and the second airbag 2. The specific structure of the airbag massage control box is as described in the above embodiments. Since this massage device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0075] The first airbag 1 and the second airbag 2 are key actuators of the massage device. They are typically made of flexible materials and can inflate and deflate. The airbags are designed to apply pressure to the user's body parts when inflated, thus achieving a massage effect. The material and structure of the airbags determine their durability and the comfort of the massage.

[0076] The airbag massage control box is the core control unit of the entire massage device, responsible for coordinating and controlling the inflation and deflation process of the airbags. It includes key components such as the air pump 20, a three-way air valve, and a control board 50. By precisely controlling the distribution of airflow, the control box enables independent or coordinated control of the airbags, thereby providing diverse massage modes.

[0077] The second three-way air valve 40 is an important component in the airbag massage control box, responsible for distributing airflow to the first airbag 1 and the second airbag 2. It switches the airflow path via electromagnetic control to ensure that the airflow can accurately flow to the corresponding airbag according to the preset program.

[0078] When the control box receives an inflation command, the air pump 20 starts and generates compressed air. The airflow enters the second three-way air valve 40 through the air circuit system. According to the control command, the second three-way air valve 40 distributes the airflow to the first airbag 1 or the second airbag 2, thereby inflating the airbag. During inflation, the precise control of the air valve ensures stable and uniform airflow, thus providing a comfortable massage experience.

[0079] During the deflation process, the control box sends a deflation command, and the second and third air valves 40 switch states, allowing the gas inside the airbag to be expelled through the air passage system. The rapid response of the air valves ensures that the airbag can deflate quickly, preparing for the next round of massage.

[0080] During the pressure-holding process, the second and third air valves 40 remain in a specific state, preventing airflow and thus maintaining the air pressure inside the airbag. This pressure-holding function ensures that the airbag can continuously apply stable pressure to the body during the massage, enhancing the massage effect.

[0081] This invention's massage device, through the rational layout of the first airbag 1, the second airbag 2, and the airbag massage control box, and the precise control of the second three-way air valve 40, ensures that airflow is accurately distributed to each airbag, realizing independent inflation, deflation, and pressure maintenance functions for the airbags. This design not only improves the precision and effectiveness of the massage but also reduces noise and vibration by optimizing the air path system, thus enhancing the user experience.

[0082] 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.
