[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 2 to 7As shown, the air bag spring of the embodiment 1 has good stability, which comprises an air pipe base 16 with an air channel 1, a plurality of air bags 2 arranged above the air pipe base 16, and an air nozzle 8 connected to the air channel 1. The air channel 1 is a lumen of the air pipe base 16, the plurality of air bags 2 are connected to the top wall of the air channel 1 along the extension direction of the air channel 1, and the inner cavities of the air bags 2 are communicated with the air channel 1. In this embodiment, four air bags 2 are connected to the top wall of the air channel 1 as an example. The top wall of the air channel 1 and the bottom wall of the air bag 2 are connected by being attached to each other, and the top wall of the air channel 1 and the bottom wall of the air bag 2 which are attached to each other are respectively provided with matching through holes 4, so that the air channel 1 is communicated with the inner cavities of the air bags 2. The air pipe base 16 is provided with support structures which protrude outward along the horizontal direction on both sides of the air pipe base 16. The support structures are pipe base seats 17 which are integrally extended from the air pipe base 16. The pipe base seats 17 on both sides of the air pipe base 16 are in the same horizontal plane and the end portions of the pipe base seats 17 are closed. The air channel 1 extends and communicates with the lumens of the pipe base seats 17. In this embodiment, the pipe base seats 17 are arranged in pairs on both sides of the air pipe base 16. The axes of the two pipe base seats 17 arranged in pairs coincide with each other. Two pipe base seats 17 arranged in pairs are arranged below each air bag 2.

[0027] Since the air pipe base is provided with pipe base seats which protrude outward along the horizontal direction on both sides of the air pipe base along the length direction as support structures, the lumens of the pipe base seats are also inflated synchronously when the air channel is inflated. The end portions of the pipe base seats are closed. After the pipe base seats are inflated, they become horizontal support air columns which are distributed on both sides of the air pipe base. Figure 7 The circle marked B in the figure is a cross-shaped air column formed by two pipe base seats arranged in pairs and the air pipe base between the two pipe base seats after inflation. This support structure increases the contact area of the air bag spring at the bottom in the downward direction. The support stability of the air bag spring is improved. The air bag can also maintain good balance when it is pressed and will not sway or tilt. This ensures that the air bag can transmit massage stimulation upward, so that the air bag can work normally.

[0028] Further, each air bag 2 is composed of a plurality of square bag bodies 3 which are stacked vertically. In this embodiment, two square bag bodies are stacked and connected as an example. Each square bag body 3 is composed of two layers of square sheets 3-1 which are attached to each other along the circumference. Two square bag bodies 3 are connected by opening matching through holes 3-2 on the two layers of square sheets 3-1 which are adjacent to each other and continuously attaching and connecting them along the circumference of the through holes. When working, the square bag bodies are repeatedly inflated and deflated, and transmit massage stimulation upward. The surface of the square sheet corresponding to the top surface of the air bag is inflated. The entire surface of the sheet serves as a massage contact surface which transmits stimulation upward. The contact area is large and the massage effect is good. The plurality of square bag bodies which are stacked vertically can increase the inflation height of the air bag as a whole and increase the vertical stroke of the massage contact surface in the upward and downward directions. The massage intensity is also improved. The massage effect is improved by the combined action of the enlarged massage contact surface and the increased massage intensity.

[0029] Further, the tracheal seat 16 and the branch pipe seats 17 on both sides thereof are formed by sealing and adhering the upper sheet 5 and the lower sheet 6 along the circumferential edge, the upper sheet 5 and the lower sheet 6 are connected by the main sheet part in the middle and the plurality of auxiliary sheet parts arranged on both sides, the main sheet parts of the two sheets are adhered to form the tracheal seat 16 when the upper sheet and the lower sheet are sealed and adhered, the auxiliary sheet parts of the two sheets are adhered to form the branch pipe seats 17, the sealing and adhering between the upper sheet and the lower sheet is achieved by hot pressing welding, the corresponding tracheal seat and branch pipe seat and the corresponding pipe cavity are formed, the sealing and adhering can also be achieved by other existing technologies; the upper sheet 5 is provided with a plurality of through holes 4 matching the air bags along the distribution direction of the air bags 2, and the air nozzle 8 is connected to the upper sheet 5 or the lower sheet 6 or between the upper sheet and the lower sheet at the end of the tracheal seat 16.

[0030] The tracheal seat and the branch pipe seats on both sides are formed by sealing and adhering the upper sheet and the lower sheet along the circumferential edge, the main sheet part corresponding to the tracheal seat and the auxiliary sheet part corresponding to the branch pipe seat are arranged on the two sheets, the main sheet parts of the two sheets are adhered to form the tracheal seat when adhered, the auxiliary sheet parts of the two sheets are adhered to form the branch pipe seats, the adhering along the circumferential edge of the upper sheet and the lower sheet can form a cavity inside the two sheets as the pipe cavity of the tracheal seat and the branch pipe seat; the through holes matching the air bags are arranged on the upper sheet along the distribution direction of the air bags; the air nozzle is connected to the upper sheet or the lower sheet or between the two sheets at the end of the tracheal seat, and the air nozzle is preferably connected to the lower sheet in the embodiment.

[0031] Further, as shown in Figure 7 The connecting edge of the main sheet part and the auxiliary sheet part can also form a convex arc edge 18. The convex arc edge can increase the area of the adhering contact, improve the firmness and sealing performance of the adhering, and the convex arc edges on the two sheets are adhered correspondingly when the upper sheet and the lower sheet are adhered along the circumferential edge, and the sealing effect between the tracheal seat and the branch pipe seat is achieved.

[0032] In order to facilitate the connection of multiple air bag springs to form a matrix arrangement of air bag distribution, the two long sides of the upper sheet 5 and / or the lower sheet 6 are provided with outwardly extending sheet extension edges 7 at the corresponding through holes 4, and positioning holes 7-1 are formed in the sheet extension edges 7. The two air bag springs can be fixed by the overlapping of the two sheet extension edges, so that the two air bag springs are connected together. When the sheet extension edges are of uniform length, the spacing of the two air bag springs can be controlled by adjusting the overlapping of the two extension edges, so as to achieve the matrix distribution of the air bags at precise intervals. Moreover, the positions of the sheet extension edges correspond to the positions of the air outlet holes, and then the connection positions of the sheet extension edges also match the air bags. The sheet extension edges on both sides of the same air bag spring are perpendicular to the air bag distribution direction and symmetrically distributed on the left and right sides, which can also reduce the vibration of the air bag during inflation and deflation. The overlapping of the two sheet extension edges can be achieved by existing ultrasonic welding or hot press welding or other common techniques. When the upper and lower sheets are provided with corresponding sheet extension edges, the two sheets are of equal length and opposite to each other on the same side of the sheet extension edges, and are attached together when the upper and lower sheets are attached and connected. The positioning holes can further accurately control the overlapping length between the two sheet extension edges. As long as the positioning holes on the two overlapping sheet extension edges coincide, the overlapping length of the two sheet extension edges can be kept consistent, thereby accurately limiting the spacing distance of the two air bag springs. Adjusting the forward and backward positions of the positioning holes on the sheet extension edges can further adjust the spacing of adjacent air bag springs, thereby changing the distribution matrix of the air bags.
