Description

Technical Field

[0001] This utility model relates to the technical field of connecting air valve structures, and in particular to a parallel valve connecting structure. Background Technology

[0002] The pneumatic massage system of a car massage chair mainly consists of an air source (air pump), an air circuit control valve assembly, a massage airbag assembly, and a control module. Its core function is to control the inflation / deflation of the airbags through air valves to simulate manual massage actions (such as squeezing and kneading). As users' demands for comfort increase, the system needs to meet the following requirements:

[0003] Precise zone control requires independent control of airbags in different areas such as the shoulders, waist, and legs to adapt to different body types and massage modes.

[0004] Existing air valves are usually individually controlled, with multiple airbags sharing a single air valve. This results in poor synchronization of inflation and deflation, making it impossible to achieve differentiated massage in different zones, leading to a monotonous user experience. The dispersed air pressure results in insufficient intensity and makes it impossible to perform complex movements such as wave-like massage.

[0005] There is a need for a new type of pneumatic control parallel valve connection structure for massage devices that can solve the problems mentioned above. Utility Model Content

[0006] This utility model provides a parallel valve connection structure, which solves the problem that the existing massager air valve control cannot achieve zoned differentiated massage and the user experience is monotonous by technically modifying the existing parallel valve.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A parallel valve connection structure includes several air valve units, a connecting air pipe, a plug, and a movable rubber nozzle. Adjacent air valve units are connected by the connecting air pipe, and the left and right ends of the connecting air pipe are respectively provided with a plug and a movable rubber nozzle. Two adjacent air valve units are fixedly connected by a fixed end.

[0009] Preferably, the air valve unit includes a housing, a rear cover, a wire frame, enameled wire, an iron core, a sealing structure, and an air nozzle. The upper end of the wire frame is fixedly connected to the rear cover, and the lower end of the wire frame is installed inside the housing. Enameled wire is sleeved on the outer periphery of the lower end of the wire frame. The enameled wire is connected to an external control system through a circuit connection wire. An iron core is installed inside the wire frame, and an air nozzle is connected to the bottom of the wire frame. The air nozzle passes through the housing and is connected to an external air source.

[0010] Preferably, the sealing structure includes a stop plate and a spring. The stop plate is disposed on the side of the iron core opposite to the air nozzle. The stop plate is used to close the air passage between the internal air passage of the iron core and the air nozzle. A spring is also disposed between the iron core and the air nozzle.

[0011] Preferably, the air nozzle is further provided with an annular groove, and an air nozzle sealing ring is installed in the annular groove, the air nozzle sealing ring being disposed in contact with the inner cavity of the wire frame.

[0012] Preferably, the outer side of the housing of the air valve unit is also provided with a fixing screw hole. The fixing end includes two iron plates and a screw. The two iron plates are arranged outside two adjacent air valve units, and the screw passes through the two iron plates and is fixedly connected to the air valve unit.

[0013] Preferably, a wire frame sealing ring is also installed at the junction of the connecting air passage at the upper end of the wire frame and the plug.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention features multiple air valve units connected in series. During use, a control signal energizes the enameled wire, generating a magnetic field in the coil. This magnetic field attracts the iron core, causing it to move upwards against spring resistance. Once the iron core moves upwards, the sealing ring between the air nozzle and the iron core disengages, opening the air nozzle channel. Compressed air enters from the air source at the bottom of the housing, passes through the vertical air passage within the wire frame, and enters the connecting air passage above. It then passes through the movable rubber air nozzle into the external airbag for inflation. The iron core remains in the attracted state, and the air nozzle remains open until the set pressure is reached, at which point the power is cut off. This application features multiple air valve units connected in series, each airbag or area equipped with an independent inflation / deflation valve (such as a two-position three-way valve). Precise control is achieved through electromagnetic drive, allowing for sequential control according to the control system to create a continuous massage effect.

[0016] The parallel solenoid valve structure integration design, by sharing the air intake channel and reusing the air path in a time-sharing manner, reduces the number of valve bodies and pipeline intersections, thus optimizing the spatial layout. Attached Figure Description

Detailed Implementation

[0022] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1-4 As shown, this utility model provides a parallel valve connection structure, including several air valve units 1, connecting air pipes 2, plugs 3 and movable rubber nozzles 4. Adjacent air valve units 1 are connected by connecting air pipes 2, and plugs 3 and movable rubber nozzles 4 are respectively provided at the left and right ends of the connecting air pipes. Two adjacent air valve units 1 are fixedly connected by fixed ends 6.

[0024] Furthermore, the air valve unit 1 includes a housing 11, a rear cover 12, a wire frame 13, an enameled wire 14, an iron core 15, a sealing structure 16, and an air nozzle 17. The upper end of the wire frame 13 is fixedly connected to the rear cover 12, and the lower end of the wire frame 13 is installed in the housing 11. The enameled wire 14 is sleeved on the outer periphery of the lower end of the wire frame 13. The enameled wire 14 is connected to the external control system through a circuit connection wire. An iron core 15 is installed inside the wire frame 13. The air nozzle 17 is connected to the bottom of the wire frame 13. The air nozzle 17 passes through the housing 11 and is connected to an external air source.

[0025] Furthermore, the sealing structure 16 includes a stop plate 161 and a spring 162. The stop plate 161 is disposed on the side of the iron core 15 opposite to the air nozzle 17. The stop plate 161 is used to close the air passage between the internal air passage of the iron core 15 and the air nozzle 17. The spring 162 is also disposed between the iron core 15 and the air nozzle 17. The spring 162 pushes the iron core 15 and the stop plate 161 to seal at the air nozzle 17. After the enameled wire 14 is energized, the iron core 15 is attracted, and the air nozzle 17 communicates with the internal air passage of the iron core 15.

[0026] Furthermore, the air nozzle 17 is also provided with an annular groove 171, and a sealing ring for the air nozzle 17 is installed in the annular groove 171. The sealing ring for the air nozzle 17 is disposed in contact with the inner cavity of the wire frame 13.

[0027] Furthermore, the outer side of the housing 11 of the air valve unit 1 is also provided with a fixing screw hole. The fixing end 6 includes two iron plates 61 and a screw 62. The two iron plates 61 are arranged outside two adjacent air valve units 1, and the screw 62 passes through the two iron plates 61 and is fixedly connected to the air valve unit 1.

[0028] Furthermore, in order to achieve a better sealing effect, a sealing ring for the wire frame 13 is also installed at the joint between the connecting air passage at the upper end of the wire frame 13 and the plug 3.

[0029] Inflation stage:

[0030] The control signal is energized through the enameled wire 14, generating a magnetic field in the coil. This magnetic field attracts the iron core 15, causing it to move upwards against the resistance of the spring 162. After the iron core 15 moves upwards, the sealing ring between the air nozzle 17 and the iron core 15 disengages, opening the air nozzle 17 channel. Compressed air enters from the air source at the bottom of the housing 11, passes through the vertical air passage within the wire frame 13, enters the connecting air passage above, and then passes through the movable rubber air nozzle 4 to inflate the external airbag. The iron core 15 remains in the attracted state, and the air nozzle 17 remains open until the set pressure is reached, at which point the power is cut off. This application features multiple air valve units 1 connected in series, each airbag or area equipped with an independent inflation / deflation valve (such as a two-position three-way valve). Precise control is achieved through electromagnetic drive, enabling sequential control according to the control system to create a continuous massage effect.

[0031] Exhaust phase:

[0032] When the enameled wire 14 is de-energized, the magnetic field disappears, the spring 162 pushes the iron core 15 back to its original position, the iron core 15 presses down on the air nozzle 17, and completely seals the air nozzle 17 channel through the sealing ring, cutting off the air source.

[0033] Each valve body's movable air nozzle 4 is independently connected to different air bags, and the main control system MCU individually controls the power supply of each valve body to achieve precise inflation in different zones.

[0034] Multiple valve bodies share the same air source input through the connecting air passage at the upper end of the wire frame 13. The air source is sealed at one end by the plug 3, and the other end is distributed to different air bags through the movable rubber nozzle 4.

[0035] This application is equipped with multiple air valve units 1 connected in series. Each airbag or area is equipped with an independent inflation / deflation valve (such as a two-position three-way valve). Precise control is achieved through electromagnetic drive. It can perform time-series control according to the control system to form a continuous massage effect.

[0036] The parallel solenoid valve structure integration design, by sharing the air intake channel and reusing the air path in a time-sharing manner, reduces the number of valve bodies and pipeline intersections, thus optimizing the spatial layout.
